    AN INVESTIGATION OF THE RELATIONSHIP BETWEEN SAFETY CLIMATE AND MEDICATION ERRORS AS WELL AS OTHER NURSE AND PATIENT OUTCOMES

    PERSONNEL PSYCHOLOGY, Issue 4 2006
    DAVID A. HOFMANN
    Safety climate has been shown to be associated with a number of important organizational outcomes. In this study, we take a broad view of safety climate,one that includes not only the development and adherence to safety protocols, but also open and constructive responses to errors,and investigate correlates within the health care industry. Drawing on a random, national sample of hospitals, the results revealed that safety climate predicted medication errors, nurse back injuries, urinary tract infections, patient satisfaction, patient perceptions of nurse responsiveness, and nurse satisfaction. As hypothesized, the relationship between safety climate and both medication errors and back injuries was moderated by the complexity of the patient conditions on the unit. Specifically, the effect of the overall safety climate of the unit was accentuated when dealing with more complex patient conditions. [source]


    Effective management of adverse effects while on oral chemotherapy: implications for nursing practice

    EUROPEAN JOURNAL OF CANCER CARE, Issue 2010

    HARROLD K. (2010) European Journal of Cancer Care19, 12,20 Effective management of adverse effects while on oral chemotherapy: implications for nursing practice The publication of guidelines by the United Kingdom National Patient Safety Agency and the National Confidential Enquiry into Patient Outcome and Death which looked into deaths within 30 days of systemic anticancer therapy and the more recent position statement from the United Kingdom Oncology Nursing Society have all highlighted the need for an improvement in the care and management of patients receiving oral chemotherapy. While it is essential that patients are aware of the rationale behind dose interruption and modification if they are to effectively deal with toxicities and complications that may arise, they also require access to a clear line of communication in order to facilitate early intervention. The value of pre treatment patient education and ongoing support for these patients has already been extensively documented and while a multidisciplinary team approach in this is vital, nurses are ideally placed to take a leading role in these two aspects of treatment management. This article aims to detail and review current best management practices for the most commonly reported toxicities associated with capecitabine, an oral chemotherapeutic agent used in the management of patients with colorectal cancer. Only if both the patient and the health care professional supporting them are aware of best management practices will the impact of toxicities be minimised and treatment outcomes optimised.

    Surgical Excision of Acoustic Neuroma: Patient Outcome and Provider Caseload

    THE LARYNGOSCOPE, Issue 8 2003
    Fred G. Barker II
    Abstract Objectives/Hypothesis For many complex surgical procedures, larger hospital or surgeon caseload is associated with better patient outcome. We examined the volume,outcome relationship for surgical excision of acoustic neuromas. Study Design Retrospective cohort study. Methods The Nationwide Inpatient Sample (1996 to 2000) was used. Multivariate regression analyses were adjusted for age, sex, race, payer, geographic region, procedure timing, admission type and source, medical comorbidities, and neurofibromatosis status. Results At 265 hospitals, 2643 operations were performed by 352 identified primary surgeons. Outcome was measured on a four-level scale at hospital discharge: death (0.5%) and discharge to long-term care (1.2%), to short-term rehabilitation (4.4%), and directly to home (94%). Outcomes were significantly better after surgery at higher-volume hospitals (OR 0.47 for fivefold-larger caseload, P <.001) or by higher-volume surgeons (OR 0.46, P <.001). Of patients who had surgery at lowest-volume-quartile hospitals, 12.3% were not discharged directly home, compared with 4.1% at highest-volume-quartile hospitals. There was a trend toward lower mortality for higher-volume hospitals (P = .1) and surgeons (P = .06). Of patients who had surgery at lowest-caseload-quartile hospitals, 1.1% died, compared with 0.6% at highest-volume-quartile hospitals. Postoperative complications (including neurological complications, mechanical ventilation, facial palsy, and transfusion) were less likely with high-volume hospitals and surgeons. Length of stay was significantly shorter with high-volume hospitals (P = .01) and surgeons (P = .009). Hospital charges were lower for high-volume hospitals (by 6% [P = .006]) and surgeons (by 6% [P = .09]). Conclusion For acoustic neuroma excision, higher-volume hospitals and surgeons provided superior short-term outcomes with shorter lengths of stay and lower charges. [source]

    Is It Time for Clinicians to Routinely Track Patient Outcome?

    CLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 3 2003
    A Meta-Analysis
    Empirically supported psychotherapies, treatment guidelines, best practices, and treatment manuals are methods proposed to enhance treatment outcomes in routine practice. Patient-focused research systems provide a compatible and contrasting methodology. Such systems monitor and feed back information about a patient's progress during psychotherapy for the purpose of enhancing outcomes. A meta-analytic review of three large-scale studies is summarized and suggests that formally monitoring patient progress has a significant impact on clients who show a poor initial response to treatment. Implementation of this feedback system reduced deterioration by 4% to 8% and increased positive outcomes. Our interpretation of these results suggests that it may be time for clinicians routinely and formally to monitor patient treatment response. [source]

    Do Palliative Consultations Improve Patient Outcomes?

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2008
    David Casarett MD
    OBJECTIVES: To determine whether inpatient palliative consultation services improve outcomes of care. DESIGN: Retrospective telephone surveys conducted with family members of veterans who received inpatient or outpatient care from a Department of Veterans Affairs (VA) medical facility in the last month of life. SETTING: Five VA Medical Centers or their affiliated nursing homes and outpatient clinics. PARTICIPANTS: Veterans had received inpatient or outpatient care from a participating VA in the last month of life. One family member completed each survey. MEASUREMENTS: The telephone survey assessed nine aspects of the care the patient received in his or her last month of life: the patient's well-being and dignity (4 items), adequacy of communication (5 items), respect for treatment preferences (2 items), emotional and spiritual support (3 items), management of symptoms (4 items), access to the inpatient facility of choice (1 item), care around the time of death (6 items), access to home care services (4 items), and access to benefits and services after the patient's death (3 items). RESULTS: Interviews were completed with 524 respondents. In a multivariable linear regression model, after adjusting for the likelihood of receiving a palliative consultation (propensity score), palliative care patients had higher overall scores: 65 (95% confidence interval (CI)=62,66) versus 54 (95% CI=51,56; P<.001) and higher scores for almost all domains. Earlier consultations were independently associated with better overall scores (,=0.003; P=.006), a difference that was attributable primarily to improvements in communication and emotional support. CONCLUSION: Palliative consultations improve outcomes of care, and earlier consultations may confer additional benefit. [source]


    Quality Improvement and Changes in Diabetic Patient Outcomes in an Academic Nurse Practitioner Primary Care Practice

    JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 12 2005
    FAANP, Thomas A. Mackey PhD
    Purpose To examine a set of system interventions in the management of patients with diabetes and the outcomes of their care. Data sources Preintervention and postintervention data collected from electronic medical records. Conclusions The sample size was smaller than expected, contributing to a lack of statistical significance from preintervention to postintervention in the patient outcome measures. The systems-level variables that were under the direct control of the clinic staff (e.g., pneumococcal vaccine given) showed great improvement. In the preintervention period, the percentage of "yes" responses to the system-level variables ranged from 8 to 24 and jumped to 16 to 95 after the intervention. Implications for practice Unequivocally, this project demonstrated that systems-level changes result in improved care being provided to patients; however, these had minimal impact on the patient outcome variables. Promoting change in patient behavior is difficult, which may have contributed to the lack of significance in this area, while the variables under the direct control of the clinic staff were more easily changed.

    Predicting Coronary Heart Disease after Kidney Transplantation: Patient Outcomes in Renal Transplantation (PORT) Study

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2010
    A. K. Israni
    Traditional risk factors do not adequately explain coronary heart disease (CHD) risk after kidney transplantation. We used a large, multicenter database to compare traditional and nontraditional CHD risk factors, and to develop risk-prediction equations for kidney transplant patients in standard clinical practice. We retrospectively assessed risk factors for CHD (acute myocardial infarction, coronary artery revascularization or sudden death) in 23 575 adult kidney transplant patients from 14 transplant centers worldwide. The CHD cumulative incidence was 3.1%, 5.2% and 7.6%, at 1, 3 and 5 years posttransplant, respectively. In separate Cox proportional hazards analyses of CHD in the first posttransplant year (predicted at time of transplant), and predicted within 3 years after a clinic visit occurring in posttransplant years 1,5, important risk factors included pretransplant diabetes, new onset posttransplant diabetes, prior pre- and posttransplant cardiovascular disease events, estimated glomerular filtration rate, delayed graft function, acute rejection, age, sex, race and duration of pretransplant end-stage kidney disease. The risk-prediction equations performed well, with the time-dependent c-statistic greater than 0.75. Traditional risk factors (e.g. hypertension, dyslipidemia and cigarette smoking) added little additional predictive value. Thus, transplant-related risk factors, particularly those linked to graft function, explain much of the variation in CHD after kidney transplantation. [source]


    Disease remission and sustained halting of radiographic progression with combination etanercept and methotrexate in patients with rheumatoid arthritis,

    ARTHRITIS & RHEUMATISM, Issue 12 2007
    D. van der Heijde
    Objective The Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes (TEMPO) is a 3-year, double-blind, multicenter study evaluating the efficacy and safety of etanercept, methotrexate, and the combination of etanercept plus methotrexate in patients with active rheumatoid arthritis (RA). The results after 1 and 2 years of the study have been previously reported. Here we provide the 3-year clinical and radiographic outcomes and safety of etanercept, methotrexate, and the combination in patients with RA. Methods In this randomized, double-blind, multicenter TEMPO study, 682 patients received etanercept 25 mg twice weekly, methotrexate ,20 mg weekly, or the combination. Key efficacy assessments included the Disease Activity Score (DAS) and the DAS in 28 joints. Results Combination therapy resulted in significantly greater improvement in the DAS and in more patients with disease in remission than either monotherapy. This finding was confirmed by longitudinal analysis; patients receiving combination therapy were more than twice as likely to have disease in remission than those receiving either monotherapy. Independent predictors of remission included male sex, lower disease activity, lower level of joint destruction, and/or better physical function. Combination and etanercept therapy both resulted in significantly less radiographic progression than did methotrexate (P < 0.05). Etanercept and combination treatment were well tolerated, with no new safety findings. Conclusion Etanercept plus methotrexate showed sustained efficacy through 3 years and remained more effective than either monotherapy, even after adjustment for patient withdrawal. Combination therapy for 3 years led to disease remission and inhibition of radiographic progression, 2 key goals for treatment of patients with RA. [source]


    Peritoneal albumin leakage: 2 year prospective cardiovascular event occurrence and patient survival analysis

    NEPHROLOGY, Issue 8 2009
    RENGIN ELSURER
    SUMMARY: Aim: High peritoneal transport status is a determinant of morbidity and mortality in peritoneal dialysis (PD) patients. It was hypothesized that 24 h peritoneal albumin leakage predicted 2 year prospective cardiovascular outcome and survival in patients receiving PD. Methods: Sixty-six patients were included. A simplified peritoneal equilibration test was performed and 24 h peritoneal albumin leakage was calculated. Patients were followed up for 2 years. Patient outcome (alive or dead) and occurrence of a cardiovascular event were recorded. Results: During a 2 year follow-up period, 10 (15.2%) patients had suffered from a cardiovascular event and seven (10.6%) patients had died. Patients who had suffered from a cardiovascular event during the follow up period were older (54.0 ± 9.4 years vs 44.3 ± 14.5 years, P = 0.025), had lower serum pre-albumin concentrations (29.3 ± 10.0 g/dL vs 36.0 ± 9.2 g/dL, P = 0.034) and had higher 24 h peritoneal albumin leakage (median, 3.4 g/day (1.66,15.4 g/day) vs 2.4 g/day (0.76,7.31 g/day), P = 0.011) than patients who did not suffer from a cardiovascular event. In the Cox proportional hazards multivariate analysis of factors which differed significantly between patients with and without a cardiovascular event (age, serum pre-albumin and 24 h peritoneal albumin leakage), only advanced age (hazards ratio, 1.083; 95% confidence interval, 1.023,1.147, P = 0.006) was an independent predictor of a cardiovascular event. Conclusion: In contrast to the hypothesis, 24 h peritoneal albumin leakage is not a predictor of 2 year prospective cardiovascular outcome and patient survival. Only advanced age independently predicts the occurrence of a cardiovascular event in patients receiving PD. [source]


    Management and Outcome of Patients With Mucoepidermoid Carcinoma of Major Salivary Gland Origin: A Single Institution's 30-Year Experience,

    THE LARYNGOSCOPE, Issue 2 2008
    Katri Aro MD
    Abstract Background: Mucoepidermoid carcinoma (MEC) is one of the most frequent epithelial malignancies of the salivary glands. Prediction of clinical outcome of MEC is challenging. Material and Methods: We retrospectively reviewed 52 cases of MEC of major salivary gland origin diagnosed at the Department of Otolaryngology,Head and Neck Surgery, Helsinki University Central Hospital, Helsinki, Finland, during a 30-year period of 1976 to 2005. Criteria used for diagnosis were those of World Health Organization classifications valid at each time point, and criteria for grading were those recommended by Armed Forces Institute of Pathology fascicle (1996). Since 1993, the degree of cell proliferation was used at our institution as an adjunct tool when grading MEC. The majority of cases occurred in the parotid gland (n = 47, 90%) followed by the submandibular gland (n = 5, 10%). Results: We had 39% high-grade (HG), 14% intermediate-grade (IMG), and 44% low-grade (LG) MECs. T categories were T1, n = 18; T2, n = 16; T3, n = 9; T4, n = 9. Forty-nine (94%) patients were treated with curative intent. These patients underwent surgery, and 24 (49%) patients received postoperative radiotherapy. Follow-up time varied from 6 months to 9 years. Forty-five percent of HG-MEC patients and 67% of IMG-MEC patients developed locoregional failures or distant metastases during a 3-year follow-up as opposed to none of the LG-MEC patients. Of MEC patients with N0 neck, two HG-MEC patients and one IMG-MEC (8%) patient developed regional recurrence during follow-up. Conclusions: Patient outcome in the different grades of MEC suggests a need for overview of the treatment protocol, especially with regard to LG-MEC and IMG-MEC. The apparently unusual occurrence of locoregional failures and metastases in LG-MEC suggests a restrictive approach in surgical management. However, the frequent occurrence of such failures in IMG-MEC warrants an aggressive approach with these tumors. [source]


    NS13P A PROSPECTIVE COMPARISON OF TWO CERVICAL INTERBODY FUSION CAGES

    ANZ JOURNAL OF SURGERY, Issue 2007
    M. A. Hansen
    Purpose For some time the surgical management of chronic back pain has utilised interbody lumbar cages. Recently interbody cages for use in the cervical spine have been produced. Cervical cages provide initial stability during the fusion process. There is little literature comparing the performance of interbody cage systems due to their relative recent introduction. Methodology Patients with symptomatic cervical degeneration or traumatic lesions were treated with the dynamic ABC 2 Aesculap anterior cervical plating system and either the B-Braun Samarys or Zimmer cage systems. A single surgeon conducted all surgery. Pre- and post-operative radiological examinations were compared. Changes in disc height at affected and adjacent levels, lordosis and evidence of fusion were recorded. Patient outcome was measured with questionnaires. The modified Oswestry neck pain disability and Copenhagen neck disability scale scores were utilised to allow comparison between patients. Results A total of 43 patients were involved in the study (30 with the Zimmer cage system and 13 with the Samarys cage). Patient follow-up has been up to 12 months. Improvement in disability scores was shown in 90% of patients. Follow up imaging did not demonstrate subsidence of the cage or adjacent instability in either group. There was no statistical difference in complication rate between the two groups. Discussion Initial stability was provided by both interbody cervical spine cage system. Rates of fusion and symptomatic relief compared favourably to fusion involving autogenous bone graft without associated morbidity. Longer follow up is necessary to determine whether there is evidence of adjacent level instability or vertebral end-plate subsidence. [source]


    Emergency Use of Extracorporeal Membrane Oxygenation in Cardiopulmonary Failure

    ARTIFICIAL ORGANS, Issue 9 2009
    Matthias Arlt
    Abstract Severe pulmonary and cardiopulmonary failure resistant to critical care treatment leads to hypoxemia and hypoxia-dependent organ failure. New treatment options for cardiopulmonary failure are necessary even for patients in outlying medical facilities. If these patients are in need of specialized center treatment, additional emergency medical service has to be carried out quick and safely. We describe our experiences with a pumpless extracorporeal lung assist (PECLA/iLA) for out-of-center emergency treatment of hypercapnic respiratory failure and the use of a newly developed hand-held extracorporeal membrane oxygenation (ECMO) system in cardiac, pulmonary, and cardiopulmonary failure (EMERGENCY-LIFE Support System, ELS System, MAQUET Cardiopulmonary AG, Hechingen, Germany). Between March 2000 and April 2009, we used the PECLA System (n = 20) and the ELS System (n = 33) in adult patients. Cannulation was employed using percutaneous vessel access. The new hand-held ELS System consists of a centrifugal pump and a membrane oxygenator, both mounted on a special holder system for storing on a standard patient gurney for air or ground ambulance transfer. Bedside cannulation processes were uneventful. The PECLA System resulted in sufficient CO2 removal. In all ECMO patients, oxygen delivery and systemic blood flow could be restored and vasopressor support was markedly down. Hospital survival rate in the PECLA group was 50%, and 61% in the ECMO group. Out-of-center emergency treatment of hypercapnic pulmonary failure with pumpless extracorporeal gas exchange and treatment of cardiac, pulmonary, and cardiopulmonary failure with this new hand-held ECMO device is safe and highlyeffective. Patient outcome in cardiopulmonary organ failure could be improved. [source]


    Utility-Based Optimization of Combination Therapy Using Ordinal Toxicity and Efficacy in Phase I/II Trials

    BIOMETRICS, Issue 2 2010
    Nadine Houede
    Summary An outcome-adaptive Bayesian design is proposed for choosing the optimal dose pair of a chemotherapeutic agent and a biological agent used in combination in a phase I/II clinical trial. Patient outcome is characterized as a vector of two ordinal variables accounting for toxicity and treatment efficacy. A generalization of the Aranda-Ordaz model (1981,,Biometrika,68, 357,363) is used for the marginal outcome probabilities as functions of a dose pair, and a Gaussian copula is assumed to obtain joint distributions. Numerical utilities of all elementary patient outcomes, allowing the possibility that efficacy is inevaluable due to severe toxicity, are obtained using an elicitation method aimed to establish consensus among the physicians planning the trial. For each successive patient cohort, a dose pair is chosen to maximize the posterior mean utility. The method is illustrated by a trial in bladder cancer, including simulation studies of the method's sensitivity to prior parameters, the numerical utilities, correlation between the outcomes, sample size, cohort size, and starting dose pair.

    Rapid Emergency Department Intervention for Older People Reduces Risk of Functional Decline: Results of a Multicenter Randomized Trial

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2001
    DrPH, Jane McCusker MD
    OBJECTIVES: To determine the effectiveness of a two-stage (screening and nursing assessment) intervention for older patients in the emergency department (ED) who are at increased risk of functional decline and other adverse outcomes. DESIGN: Controlled trial, randomized by day of ED visit, with follow-up at 1 and 4 months. SETTING: Four university-affiliated hospitals in Montreal. PARTICIPANTS: Patients age 65 and older expected to be released from the ED to the community with a score of 2 or more on the Identification of Seniors At Risk (ISAR) screening tool and their primary family caregivers. One hundred seventy-eight were randomized to the intervention, 210 to usual care. INTERVENTION: The intervention consisted of disclosure of results of the ISAR screen, a brief standardized nursing assessment in the ED, notification of the primary care physician and home care providers, and other referrals as needed. The control group received usual care, without disclosure of the screening result. MEASUREMENTS: Patient outcomes assessed at 4 months after enrollment included functional decline (increased dependence on the Older American Resources and Services activities of daily living scale or death) and depressive symptoms (as assessed by the short Geriatric Depression Scale). Caregiver outcomes, also assessed at baseline and 4 months, included the physical and mental summary scales of the Medical Outcomes Study Short Form-36. Patient and caregiver satisfaction with care were assessed 1 month after enrollment. RESULTS: The intervention increased the rate of referral to the primary care physician and to home care services. The intervention was associated with a significantly reduced rate of functional decline at 4 months, in both unadjusted (odds ratio (OR) = 0.60, 95% confidence interval (CI) = 0.36,0.99) and adjusted (OR = 0.53, 95% CI = 0.31,0.91) analyses. There was no intervention effect on patient depressive symptoms, caregiver outcomes, or satisfaction with care. CONCLUSION: A two-stage ED intervention, consisting of screening with the ISAR tool followed by a brief, standardized nursing assessment and referral to primary and home care services, significantly reduced the rate of subsequent functional decline.

    Liver Transplantation Using Donation After Cardiac Death Donors: Long-Term Follow-Up from a Single Center

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2009
    M. E. De Vera
    There is a lack of universally accepted clinical parameters to guide the utilization of donation after cardiac death (DCD) donor livers and it is unclear as to which patients would benefit most from these organs. We reviewed our experience in 141 patients who underwent liver transplantation using DCD allografts from 1993 to 2007. Patient outcomes were analyzed in comparison to a matched cohort of 282 patients who received livers from donation after brain death (DBD) donors. Patient survival was similar, but 1-, 5- and 10-year graft survival was significantly lower in DCD (69%, 56%, 44%) versus DBD (82%, 73%, 63%) subjects (p < 0.0001). Primary nonfunction and biliary complications were more common in DCD patients, accounting for 67% of early graft failures. A donor warm ischemia time >20 min, cold ischemia time >8 h and donor age >60 were associated with poorer DCD outcomes. There was a lack of survival benefit in DCD livers utilized in patients with model for end-stage liver disease (MELD) ,30 or those not on organ-perfusion support, as graft survival was significantly lower compared to DBD patients. However, DCD and DBD subjects transplanted with MELD >30 or on organ-perfusion support had similar graft survival, suggesting a potentially greater benefit of DCD livers in critically ill patients.

    Laparoscopic anterior resection for rectosigmoid cancer: Patient outcomes after implementation of a clinical pathway

    ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 1 2010
    T.W. Hsu
    Abstract Introduction: A clinical pathway designed for a single type of laparoscopic colorectal surgery for cancer might be helpful in decreasing complication rates and total hospital costs. It has been reported to be effective in reducing costs and shortening length of hospital stays in many situations such as laparoscopic cholecystectomy, colon resection, total colectomy, and gastrointestinal bleeding, as well as when caring for patients in the intensive care unit. Materials and Methods: A clinical pathway, including surgical details and perioperative management, for patients undergoing laparoscopic anterior resection for rectosigmoid cancer was designed and implemented. From January 2003 to December 2006, it was applied to 80 patients. Results: The average length of a hospital stay for these patients was 9.06 d. The mean hospital stay and total cost decreased year by year. The overall complication rate was 8.75% without perioperative mortality, and 47.5% of patients with underlying diseases were treated safely. Discussion: Laparoscopic anterior resection for rectosigmoid cancer, with curative or palliative intent, was safe after standardization of surgical details and perioperative management. The total hospital costs for each patient was predictable and decreased year by year. [source]


    Patient outcomes and length of hospital stay after radical prostatectomy for prostate cancer: analysis of Hospital Episodes Statistics for England

    BJU INTERNATIONAL, Issue 5 2007
    Andrew Judge
    OBJECTIVE To investigate the morbidity and mortality after radical prostatectomy (RP) in relation to the numbers of RPs carried out at individual hospitals, as recent studies of complex surgery report worse outcomes in low-volume hospitals, and there has been a large increase in RPs for localized prostate cancer. METHODS We analysed hospital episode statistics data for all 18 027 RPs in English National Health Service hospitals between 1997 and 2004. RESULTS In multivariate analysis, there was a U,shaped association of hospital volume with mortality (P for nonlinear trend, 0.004), but this finding was based on only 59 (0.3%) deaths. The mean length of stay was 6 days and decreased by 2.96% (95% confidence interval, CI, 1.98,3.92; P < 0.001) per quintile increase in hospital volume. In all, 16.1% of men had 30-day in-hospital complications; 20.3% were readmitted with complications within a year. The odds of 30-day in-hospital wound/bleeding complications decreased by 6% (95% CI 1,11; P = 0.02), and miscellaneous medical complications decreased by 10% (0,19; P = 0.04) per increase in hospital volume quintile. For re-admissions within a year, the hazard of vascular complications decreased by 15% (6,22; P = 0.001), wound/bleeding complications decreased by 8% (2,13; P = 0.01) and genitourinary complications decreased by 5% (2,8; P = 0.002), per increase in hospital volume quintile. CONCLUSION In men undergoing RP the length of hospital stay and rates of some short- and long-term postoperative complications afterward are lower in high-volume hospitals. The magnitudes of these effects on the outcomes studied may be too small and inconsistent to indicate a policy of selective referral to high-volume hospitals. Quality of life and oncological outcomes, however, could not be investigated in this dataset. [source]


    Outcome of Pulmonary Valve Replacements in Adults after Tetralogy Repair: A Multi-institutional Study

    CONGENITAL HEART DISEASE, Issue 3 2008
    Thomas P. Graham Jr. MD
    ABSTRACT Objective., The purpose of this study was to assess the outcome of pulmonary valve replacement (PVR) in adults with moderate/severe pulmonary regurgitation after tetralogy repair, with particular emphasis on patient outcome, durability of valve repair, and improvement in symptomatology. Design/Setting/Patients., The project committee of the International Society of Congenital Heart Disease undertook a retrospective multi-institutional analysis of PVR. Seven centers participated in submitting data on 93 patients >18 years of age who had the operation performed and follow-up obtained. The average age of PVR was 26± years (median 27 years). Time of follow-up after replacement was 3 years (range 4 days,28 years). Outcomes/Measures/Results., Kaplan,Meier estimates of durability of PVR showed approximately 50% replacement at 11 years. There were two deaths at 6 and 12 months after valve replacement. Right ventricular (RV) size estimated by echocardiography from pre- to postoperative studies decreased in 81% (P < 0.001 testing for equal proportions), but RV systolic function increased in only 36% (P = 0.09). Ability index improved in 59% (P < 0.001) and clinical heart failure status improved in 57% with this problem before PVR. PVR did not improve arrhythmia status in a small group of patients. Conclusions., PVR is associated with low mortality, decrease in RV size and improvement in ability index, and uncertain effects on RV systolic function. Average valve durability was approximately 11 years. Criteria for PVR that will preserve RV function are not clearly identified, and management of these patients remains a difficult enterprise.

    ABSTRACT:, The proper method of biopsy and definitive surgical excision of cutaneous melanoma is vital for optimal patient outcome. Clearly, the present authors' understanding of the pathophysiology of cutaneous melanoma continues to change at a rapid pace. Indeed, as the present authors' research efforts begin to expose some of the mysteries of melanoma, so do they begin to better understand the intricacies of this dreaded cancer. This article will highlight methods of biopsy for melanoma and the management of the primary tumor. The present authors review current recommendations for excision margins for the primary tumor, usefulness of lymphoscintigraphy, timing of definitive surgical excision, and issues unique for head and neck melanoma.

    Effects of implementation of psychiatric guidelines on provider performance and patient outcome: systematic review

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2007
    S. Weinmann
    Objective:, To identify evidence from comparative studies on the effects of psychiatric guideline implementation on provider performance and patient outcome. Effects of different implementation strategies were reviewed. Method:, Articles published between 1966 and March 2006 were searched through electronic databases and hand search. A systematic review of comparative studies of structured implementation of specific psychiatric guidelines was performed. Rates of guideline adherence, provider performance data, illness detection and diagnostic accuracy rates were extracted in addition to patient relevant outcome data. Results:, Eighteen studies (nine randomized-controlled trials, six non-randomized-controlled studies and three quasiexperimental before-and-after studies) were identified. Effects on provider performance or patient outcome were moderate and temporary in most cases. Studies with positive outcomes used complex multifaceted interventions or specific psychological methods to implement guidelines. Conclusion:, There is insufficient high-quality evidence to draw firm conclusions on the effects of implementation of specific psychiatric guidelines. [source]


    Protein alterations in ESCC and clinical implications: a review

    DISEASES OF THE ESOPHAGUS, Issue 1 2009
    D.-C. Lin
    SUMMARY Esophageal squamous cell carcinoma (ESCC) is the predominant histological subtype of esophageal cancer in Asia, characterized by high incidence and mortality rate. Although significant progress has been made in surgery and adjuvant chemoradiotherapy, the prognosis of the patients with this cancer still remains poor. Investigation into protein alterations that occurred in tumors can provide clues to discover new biomarkers for improving diagnosis and guiding targeted therapy. Hundreds of papers have appeared over the past several decades concerning protein alterations in ESCC. This review summarizes all the dysregulated proteins investigated in the disease from 187 published papers and analyzes their contributions to tumor development and progression. We document protein alterations associated with tumor metastasis and the transition from normal esophageal epithelia to dysplasia in order to reveal the most useful markers for prediction of clinical outcome, early detection, and identification of high-risk patients for targeted therapies. In particluar, we discuss the largest and most rigorous studies on prognostic implications of proteins in ESCC, in which cyclin D1, p53, E-cadherin and VEGF appeared to have the strongest evidence as independent predictors of patient outcome.

    Prospective Study of Accuracy and Outcome of Emergency Ultrasound for Abdominal Aortic Aneurysm over Two Years

    ACADEMIC EMERGENCY MEDICINE, Issue 8 2003
    Vivek S. Tayal MD
    Abstract Determination of the presence of an abdominal aortic aneurysm (AAA) is essential in the management of the symptomatic emergency department (ED) patient. Objectives: To identify whether emergency ultrasound of the abdominal aorta (EUS-AA) by emergency physicians could accurately determine the presence of AAA and guide ED disposition. Methods: This was a prospective, observational study at an urban ED with more than 100,000 annual patient visits with consecutive patients enrolled over a two-year period. All patients suspected to have AAA underwent standard ED evaluation consisting of EUS-AA, followed by a confirmatory imaging study or laparotomy. AAA was defined as any measured diameter greater than 3 cm. Demographic data, results of confirmatory testing, and patient outcome were collected by retrospective review. Results: A total of 125 patients had EUS-AA performed over a two-year period. The patient population had the following characteristics: average age 66 years, male 54%, hypertension 56%, coronary artery disease 39%, diabetes 22%, and peripheral vascular disease 14%. Confirmatory tests included radiology ultrasound, 28/125 (22%); abdominal computed tomography, 95/125 (76%); abdominal magnetic resonance imaging, 1/125 (1%); and laparotomy, 1/125 (1%). AAA was diagnosed in 29/125 (23%); of those, 27/29 patients had AAA on confirmatory testing. EUS-AA had 100% sensitivity (95% CI = 89.5 to 100), 98% specificity (95% CI = 92.8 to 99.8), 93% positive predictive value (27/29), and 100% negative predictive value (96/96). Admission rate for the study group overall was 70%. Immediate operative management was considered in 17 of 27 (63%) patients with AAA; ten patients were taken to the operating room. Conclusions: EUS-AA in a symptomatic population for AAA is sensitive and specific. These data suggest that the presence of AAA on EUS-AA should guide urgent consultation. Emergency physicians were able to exclude AAA regardless of disposition from the ED. [source]


    A critical reappraisal of treatment response criteria in systemic mastocytosis and a proposal for revisions

    EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 5 2010
    A. Pardanani
    Abstract Mast cell disease (MCD) is a hematopoietic stem cell neoplasm that is associated with infiltration of one or more organs with cytologically abnormal mast cells (MC). MCD is frequently but not always associated with a KIT mutation and, in some cases, is associated with clonal expansion of non-MC lineage cells. In adults, there is almost always MC infiltration of the bone marrow, which is a cardinal feature of systemic mastocytosis (SM). While, as members of the wider community of physician scientists, we recognize the contribution of the current consensus treatment response criteria for SM, as individuals with more than average clinical experience in SM, we would like to point out their limitations and engage in a constructive discussion that will hopefully lead to a consideration for revisions. We present here an alternative proposal for treatment response assessments we believe is more objective, reproducible, and importantly, SM-subtype specific, given the recent progress in our understanding of the natural history of this disease. We believe this proposal is timely given the prospects for new clinical trials in SM, and the related regulatory aspects of new drug approval that are currently not adequately addressed. The intent of this exercise is not to undermine the complexity of the disease or previous work by other investigators, but to come up with ideas for response criteria that are more practical and consider meaningful patient outcome.

    Application of pharmacokinetic modelling to the routine therapeutic drug monitoring of anticancer drugs

    FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 4 2002
    Annick Rousseau
    Abstract Over the last 10 years, proofs of the clinical interest of therapeutic drug monitoring (TDM) of certain anticancer drugs have been established. Numerous studies have shown that TDM is an efficient tool for controlling the toxicity of therapeutic drugs, and a few trials have even demonstrated that it can improve their efficacy. This article critically reviews TDM tools based on pharmacokinetic modelling of anticancer drugs. The administered dose of anticancer drugs is sometimes adjusted individually using either a priori or a posteriori methods. The most frequent clinical application of a priori formulae concerns carboplatin and allows the computation of the first dose based on biometrical and biological data such as weight, age, gender, creatinine clearance and glomerular filtration rate. A posteriori methods use drug plasma concentrations to adjust the subsequent dose(s). Thus, nomograms allowing dose adjustment on the basis of blood concentration are routinely used for 5-fluorouracil given as long continuous infusions. Multilinear regression models have been developed, for example for etoposide, doxorubicin, carboplatin, cyclophosphamide and irinotecan, to predict a single exposure variable [such as area under concentration,time curve (AUC)] from a small number of plasma concentrations obtained at predetermined times after a standard dose. These models can only be applied by using the same dose and schedule as the original study. Bayesian estimation offers more flexibility in blood sampling times and, owing to its precision and to the amount of information provided, is the method of choice for ensuring that a given patient benefits from the desired systemic exposure. Unlike the other a posteriori methods, Bayesian estimation is based on population pharmacokinetic studies and can take into account the effects of different individual factors on the pharmacokinetics of the drug. Bayesian estimators have been used to determine maximum tolerated systemic exposure thresholds (e.g. for topotecan or teniposide) as well as for the routine monitoring of drugs characterized by a very high interindividual pharmacokinetic variability such as methotrexate or carboplatin. The development of these methods has contributed to improving cancer chemotherapy in terms of patient outcome and survival and should be pursued. [source]


    Sentinel node biopsy and head and neck tumors,Where do we stand today?

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 12 2006
    FCAP, Kenneth O. Devaney MD
    Abstract Background. Sentinel lymph node sampling may be studied profitably in series of patients with 1 tumor type, such as breast carcinoma, in 1 anatomic locale. The present work analyzes the efficacy of sentinel node sampling in a pathologically diverse group of lesions from an anatomically diverse region such as the head and neck; however, there are risks conflating the findings in different tumors with radically different behaviors, in the process producing muddled data. This report reviews the head and neck experience with sentinel sampling and concludes that certain tumor types that have a known propensity for aggressive behavior are the best candidates for trials employing sentinel node sampling; candidates include many cutaneous melanomas of the head and neck, oropharyngeal squamous carcinomas, and selected thyroid carcinomas. Despite the growing popularity of sentinel node sampling in a variety of regions of the body, however, at this juncture this technique remains an investigational procedure, pending demonstration of a tangible improvement in patient outcome through its use. It is recommended that studies of the efficacy of this technique strive, whenever possible, to segregate results of different tumor types in different head and neck locales from one another so as to produce more focused findings for discrete types of malignancies, and not group together tumor types that may in reality exhibit different biological behaviors. © 2006 Wiley Periodicals, Inc.

    Aims:, Multidrug resistance is a major impediment in chemotherapeutic treatment of ovarian carcinoma patients. The aim of this study was to investigate the expression of multidrug resistance-associated protein 1 (MRP1) and to assess the possible associations with clinicopathological variables and patient outcome in primary ovarian carcinoma. Methods and results:, Tumour specimens from 129 patients were obtained before chemotherapy and analysed by immunohistochemistry on tissue microarrays, and by real-time reverse transcriptase-polymerase chain reaction on RNA extracted from formalin-fixed paraffin-embedded tissue specimens using a new technique. Significantly increased MRP1 protein expression was observed in high-grade tumours (P = 0.005) and advanced International Federation of Gynaecology and Obstetrics stages (P = 0.036). On univariate Kaplan,Meier analysis, patients with higher expression of MRP1 protein had significantly decreased overall survival (P = 0.006). On multivariate Cox regression analysis, MRP1 protein expression retained its significance as an independent negative prognostic marker for overall survival (hazard ratio = 6.52, P = 0.003). Furthermore, MRP1 expression correlated with topoisomerase II, expression both at mRNA and protein level (P < 0.001 and P = 0.023, respectively). Conclusion:, In summary, in patients with primary ovarian cancer, overexpression of MRP1 is an adverse marker for patient outcome and cancer aggressiveness. Our data provide a translational basis for further clinical studies on the predictive value of MRP1 expression for response to chemotherapy. [source]


    Tenascin-C in primary malignant melanoma of the skin

    HISTOPATHOLOGY, Issue 4 2004

    Aims :,To investigate the expression and the prognostic role of glycoprotein Tenascin-C (Tn-C) in primary melanoma of the skin. Methods and results :,The immunohistochemical expression of Tn-C was studied in 98 primary melanomas and related to inflammation, invasion, and patient outcome. Patients were followed up for disease recurrence for 0.04,7.4 years (median 3.9) and for survival for 0.5 to 12.1 years (median 9.3). The expression of Tn-C was evaluated for each tumour invasion border; the stromal and intracytoplasmic Tn-C of the melanoma islets were also recorded. Tn-C is widely expressed in primary melanoma samples, the staining pattern varying from focal to diffuse in different parts of the tumour. No correlation existed between intensity of Tn-C staining and inflammation. No stromal Tn-C was detected at the upper dermal lateral border in 12 patients, nor at the deep, dermal or subcutaneous border in 14 patients. These patients showed better disease-free survival (DFS) than did those cases with focal or diffuse staining (P = 0.06, P = 0.05). Also, absence of intracytoplasmic Tn-C was a beneficial prognostic factor for DFS (P = 0.04). In multivariate analysis, tumour ulceration and intracytoplasmic Tn-C expression of melanoma cells were independent adverse prognostic factors for DFS. Conclusions :,In primary melanoma of the skin, absence of Tn-C in the stroma of invasion fronts and within tumour cells seems to be related to a more benign disease behaviour with a lower risk of developing metastases.

    Somatic NF1 mutation spectra in a family with neurofibromatosis type 1: Toward a theory of genetic modifiers,

    HUMAN MUTATION, Issue 6 2003
    Verena Wiest
    Abstract Neurofibromatosis type 1 (NF1), an autosomal dominantly-inherited disorder, is mainly characterized by the occurrence of multiple dermal neurofibromas and is caused by mutations in the NF1 gene, a tumor suppressor gene. The variable expressivity of the disease and the lack of a genotype/phenotype correlation prevents any prediction of patient outcome and points to the action of genetic factors in addition to stochastic factors modifying the severity of the disease. The analysis of somatic NF1 gene mutations in neurofibromas from NF1 patients revealed that each neurofibroma results from an individual second hit mutation, indicating that factors that influence somatic mutation rates may be regarded as potential modifiers of NF1. A mutational screen of numerous neurofibromas from two NF1 patients presented here revealed a predominance of point mutations, small deletions, and insertions as second hit mutations in both patients. Seven novel mutations are reported. Together with the results of studies that showed LOH as the predominant second hit in neurofibromas of other patients, our results suggest that in different patients different factors may influence the somatic mutation rate and thereby the severity of the disease.
