Patients' Health (patient + health)
Terms modified by Patients' Health Selected AbstractsManaging oral anticoagulation therapy: improving clinical outcomes.JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 6 2008A review Summary Many physicians are reluctant to prescribe oral anticoagulation therapy (OAT) because of the fear of haemorrhagic complications. Changes in patient health, lifestyle or diet and other drugs can alter the effectiveness of oral anticoagulants. These potential interferences, added to the fact that each individual has a different reaction to these drugs, requires that therapy is monitored regularly. This article aims to review those strategies which help to achieve optimal anticoagulation control and improve the outcomes of OAT. Relevant articles were identified through a search of MEDLINE and included publications reporting on intensity of anticoagulation, the initiation of therapy and the role of pharmacogenetics, the transition from primary to secondary care, management by specialized clinics using decision support software and home-testing. Implementation of these strategies would increase the use of oral anticoagulants by physicians and offers the potential to improve patient safety and reduce adverse events. [source] Optimal control of innate immune responseOPTIMAL CONTROL APPLICATIONS AND METHODS, Issue 2 2002Robert F. Stengel Abstract Treatment of a pathogenic disease process is interpreted as the optimal control of a dynamic system. Evolution of the disease is characterized by a non-linear, fourth-order ordinary differential equation that describes concentrations of pathogens, plasma cells, and antibodies, as well as a numerical indication of patient health. Without control, the dynamic model evidences sub-clinical or clinical decay, chronic stabilization, or unrestrained lethal growth of the pathogen, depending on the initial conditions for the infection. The dynamic equations are controlled by therapeutic agents that affect the rate of change of system variables. Control histories that minimize a quadratic cost function are generated by numerical optimization over a fixed time interval, given otherwise lethal initial conditions. Tradeoffs between cost function weighting of pathogens, organ health, and use of therapeutics are evaluated. Optimal control solutions that defeat the pathogen and preserve organ health are demonstrated for four different approaches to therapy. It is shown that control theory can point the way toward new protocols for treatment and remediation of human diseases. Copyright © 2002 John Wiley & Sons, Ltd. [source] Endotoxin Level Measurement in Hemodialysis Biofilm Using "The Whole Blood Assay"ARTIFICIAL ORGANS, Issue 6 2005Karine Marion-Ferey Abstract:, Biofilms have been found on the inner surface of silicone tubing inside dialysis machines. Endotoxin releasing from those biofilms increases the bioincompatibility of dialysis liquids and leads to long-term inflammatory complications among dialysis patients. Endotoxin measurement is recommended for the control of dialysis liquids. This article describes the use of a new method, the Whole Blood Assay (WBA), for endotoxin quantification in dialysis biofilms. Biofilms were suspended in sterile water by scraping the tubing samples. Diluted blood samples from healthy donors were stimulated overnight with the contaminated suspension. Stimulated mononuclear cells released IL-1, in response to endotoxins. IL-1, level was then measured using an ultrasensitive ELISA method. We demonstrated a semilogarithmic model in which the optical densities measured after the ELISA assay increases linearly with the levels of endotoxin. This model allowed the determination of the amount of endotoxins in biofilm samples with a detection limit of 0.032 EU/mL. Most of the time, the amounts of endotoxin measured by the WBA were higher than those measured by the Limulus Amoebocyte Lysate (LAL) assay. This study suggested the presence of "endotoxin-like" compounds different from the lipopolysaccharides that are not detected by the LAL assay. We concluded that the LAL is necessary but insufficient to have a representative quantification of endotoxins that could be hazardous to patient health. [source] Schizophrenia and weight management: a systematic review of interventions to control weightACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2003G. Faulkner Objective: Weight gain is a frequent side effect of antipsychotic medication which has serious implications for a patient's health and well being. This study systematically reviews the literature on the effectiveness of interventions designed to control weight gain in schizophrenia. Method: A systematic search strategy was conducted of major databases in addition to citation searches. Study quality was rated. Results: Sixteen studies met the inclusion criteria. Five of eight pharmacological intervention studies reported small reductions in weight (<5% baseline body weight). All behavioural (including diet and/or exercise) interventions reported small reductions in, or maintenance of, weight. Conclusion: Weight loss may be difficult but it is not impossible. Given the inconsistent results, the widespread use of pharmacological interventions cannot be recommended. Both dietary and exercise counselling set within a behavioural modification programme is necessary for sustained weight control. [source] Detention of the mentally ill in Europe , a reviewACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2002Martin Zinkler Objective:,The frequency of compulsory admission varies widely across Europe. Although there has been some research on a nation-wide level, no work has been done to compare mental health legislation in different countries in relation to detention rates and to patients' perception of hospital detention. Method:,Databases and government statistics were searched for regional, national and European data. Legal frameworks were compared and reviewed in relation to patients' and professionals' views. Results:,Nearly 20-fold variations in detention rates were found in different parts of Europe. Criteria for detention of the mentally ill are broadly similar when it comes to patients at risk to themselves or others. However different rules apply for involuntary treatment in the interest of the patient's health. Conclusion:,Variations in detention rates across Europe appear to be influenced by professionals' ethics and attitudes, sociodemographic variables, the public's preoccupation about risk arising from mental illness and the respective legal framework. [source] Obtaining a thorough sleep history and routinely screening for obstructive sleep apneaJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2008FNP-BC, Jamie Lamm RN Abstract Purpose: To present a clinical case study of obstructive sleep apnea (OSA) and discuss a potential correlation between OSA, unexplained distal pain symptoms, and pyschoemotional concerns. Data sources: A review of the scientific literature was performed on OSA using the Cumulative Index of Nursing and Allied Health Literature and MEDLINE. Conclusions: OSA is potentially life threatening and can have serious consequences to a patient's health. Many of the obvious signs of OSA occur at night, and the symptoms of OSA may correspond to a variety of other diseases. Clinicians should recognize a possible correlation between OSA and unexplained distal pain symptoms as well as psychoemotional concerns. These clinically associated conditions may be less apparent but may dramatically affect quality of life. By improving recognition and treatment of OSA, morbidity and mortality can be reduced and quality of life can be improved for patients and their families. Implications for practice: It is imperative that clinicians are attentive and take detailed histories to recognize the clinical signs and symptoms of OSA, paying more attention to the less obvious symptomatology that may be significantly impacting quality of life. [source] Topical antifungal drugs for the treatment of onychomycosis: an overview of current strategies for monotherapy and combination therapyJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 1 2005R Baran ABSTRACT Background, Onychomycosis is a relatively common disease accounting for up to 50% of all nail disorders and its prevalence rises with age. As onychomycosis is an important medical disorder affecting both patient's health and quality of life, it requires prompt and effective treatment. Objective, Topical antifungal nail lacquers have been formulated to provide efficient delivery to the nail unit. As both amorolfine and ciclopirox have proved useful as monotherapy for onychomycosis that does not involve the nail matrix area, the purpose of this article is to check if, when combined with oral agents, the effectiveness and scope of treatment can be improved further. Methods, Combining data for mycological cure with clinical success (nail morphology) provides a more exacting efficacy measure. Results, Clinical investigations have shown that the combination of oral therapies with antifungal nail lacquer can confer considerable advantage over monotherapy with either drug type. Conclusion, The improved effectiveness and economic advantages of combined topical/oral therapies benefit both patients and health providers; these treatment regimens therefore have an important role to play in the modern management of onychomycosis. [source] Impact of Provider Self-Management Education, Patient Self-Efficacy, and Health Status on Patient Adherence in Heart Failure in a Veterans Administration PopulationCONGESTIVE HEART FAILURE, Issue 1 2008Usha Subramanian MD To address the need for more information on predictors of adherence to heart failure (HF) self-management regimens, this study analyzed surveys completed by 259 HF patients receiving care at 2 Veterans Affairs hospitals in 2003. Linear multivariable regression models were used to examine general health status, HF-specific health status (Kansas City Cardiomyopathy Questionnaire) self-management education, and self-efficacy as predictors of self-reported adherence to salt intake and exercise regimens. Self-management education was provided most often for salt restriction (87%) followed by exercise (78%). In multivariable regression analyses, education about salt restriction (P=.01), weight reduction (P=.0004), self-efficacy (P=.03), and health status (P=.003) were significantly associated with patient-reported adherence to salt restriction. In a similar model, self-efficacy (P=.006) and health status (P,.0001), but not exercise education, were significantly associated with patient-reported exercise adherence. Findings suggest that provider interventions may lead to improved adherence with HF self-management and thus improvements in patients' health. [source] Surface electrical stimulation of the quadriceps femoris in patients affected by haemophilia AHAEMOPHILIA, Issue 6 2006F. QUEROL Summary., Eighteen sessions of surface electrical stimulation was applied to the quadriceps femoris of the left leg of ten male subjects affected by severe haemophilia A, while ten healthy subjects constituted the control group. The isometric strength, the electromyographic activity and the diameter of the rectus femoris were measured in both legs before and after a six-week treatment period. After the treatment, the people affected by haemophilia showed a gain in strength by 13.8% in the stimulated leg and by 17.1% in the non-stimulated one. No changes were detected in the electromyographic activity. On the contrary, the diameter of the rectus femoris of the stimulated leg increased in 24.34%, while no significant change was found in the nonelectrically stimulated leg. These results show for the first time that the application of electrical stimulation in haemophilic patients contributes to the gain and development of strength and trophism. The results also show that the surface electrical stimulation does not represent a threat to the patients' health, and that can be used for therapeutic purposes. [source] Predictors of entering 24-h care for people with Alzheimer's disease: results from the LASER-AD studyINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 11 2009Stephanie Habermann Abstract Objectives Many studies have investigated predictors of people with dementia entering 24-h care but this is the first to consider a comprehensive range of carer and care recipient (CR) characteristics derived from a systematic review, in a longitudinal cohort study followed up for several years. Methods We interviewed 224 people with Alzheimer's disease (AD) and their carers, recruited to be representative in terms of their severity, sex and living situation as part of the LASER-AD study; and determined whether they entered 24-h care in the subsequent 4.5,years. We tested a comprehensive range of characteristics derived from a systematic review, and used Cox proportional hazard regression to determine whether they independently predicted entering 24-h care. Results The main independent predictors of shorter time to enter 24-h care were the patient being: more cognitively or functionally impaired (hazard ratio (HR),=,1.09; 95% CI,=,1.06,1.12) and (HR,=,1.04 95% CI,=,1.03,1.05), having a paid versus a family carer (HR,=,2.22; 95% CI,=,1.39,3.57), the carer being less educated (HR,=,1.43; 95% CI,=,1.12,1.83) and spending less hours caring (HR,=,1.01; 95% CI,=,1.00,1.01). Conclusion As having a family carer who spent more time caring (taking into account illness severity) delayed entry to 24-h care, future research should investigate how to enable carers to provide this. Other interventions to improve patients' impairment may not only have benefits for patients' health but also allow them to remain longer at home. This financial benefit could more than offset the treatment cost. Copyright © 2009 John Wiley & Sons, Ltd. [source] Nursing students' perceptions of the importance of caring behaviorsJOURNAL OF ADVANCED NURSING, Issue 4 2008Zahra Khademian Abstract Title.,Nursing students' perceptions of the importance of caring behaviours Aim., This paper is a report of a study to determine the nursing students' perceptions of the importance of caring behaviours. Background., Caring has been considered as the essence of nursing. It is believed that caring enhances patients' health and well-being and facilitates health promotion. Nursing education has an important role in educating the nurses with adequate caring abilities. Method., Ninety nursing students (response rate 75%) responded to a questionnaire consisting of 55 caring behaviours adapted from items on Caring Assessment Questionnaire (Care-Q). Behaviours were ranked on a 5-point Likert-type scale. The caring behaviours were categorized in seven subscales: ,accessibles', ,monitors and follows through', ,explains and facilitates', ,comforts', ,anticipates', ,trusting relationship' and ,spiritual care'. Data were collected in Iran in 2003. Findings., The students perceived ,monitors and follows through' (mean = 4·33, SD = 0·60) as the most and ,trusting relationship' (mean = 3·70, SD = 0·62) as the least important subscales. ,To give patient's treatments and medications on time' and ,to do voluntarily little things,' were the most and least important caring behaviours, respectively. ,Explains and facilitates' statistically and significantly correlated with age (r = 0·31, P = 0·003) and programme year (r = 0·28, P = 0·025). Gender had no statistically significant influence on students' perceptions of caring behaviours. Conclusion., Further research is needed, using longitudinal designs, to explore nursing students' perceptions of caring behaviours in different cultures, as well as evaluation studies of innovations in curriculum and teaching methods to improve learning in relation to cultural competence and caring concepts. [source] Predictors of health-related quality of life in patients with chronic liver diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2009A. AFENDY Summary Background, Patient-reported outcomes like health-related quality of life (HRQL) have become increasingly important for full assessment of patients with chronic liver diseases (CLD). Aim, To explore the relative impact of different types of liver disease on HRQL as well as predictors of HRQL domains in CLD. Methods, Our HRQL databases with Short-Form 36 (SF-36) data were used. Scores for each of SF-36 scales (PF , physical functioning, RP , role functioning, BP , bodily pain, GH , general health, VT , vitality, SF , social functioning, RE , role emotional and MH , mental health, MCS , mental component score, PCS , physical component score) were compared between different types of CLD as well as other variables. Results, Complete data were available for 1103 CLD patients. Demographic and clinical data included: age 54.2 ± 12.0 years, 40% female, 761 (69%) with cirrhosis. Analysis revealed that age correlated significantly (P < 0.05) with worsening HRQL on every scale of the SF-36. Female patients had more HRQL impairments in PF, RP, BP, GH, VT and MH scales of SF-36 (, scale score: 6.6,10.7, P < 0.05). Furthermore, cirrhotic patients had more impairment of HRQL in every scale of SF-36 (, scale score: 6.6,43.0, P < 0.05). In terms of diagnostic groups, non-alcoholic fatty liver disease patients showed more impairment of HRQL. Conclusions, Analysis of this large CLD cohort suggests that a number of important clinicodemographic factors are associated with HRQL impairment. These findings contribute to the full understanding of the total impact of CLD on patients' health. [source] Process of Care Events in Transplantation: Effects on the Cost of HospitalizationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2010N. N. Egorova Deviations in the processes of healthcare delivery that affect patient outcomes are recognized to have an impact on the cost of hospitalization. Whether deviations that do not affect patient outcome affects cost has not been studied. We have analyzed process of care (POC) events that were reported in a large transplantation service (n = 3,012) in 2005, delineating whether or not there was a health consequence of the event and assessing the impact on hospital resource utilization. Propensity score matching was used to adjust for patient differences. The rate of POC events varied by transplanted organ: from 10.8 per 1000 patient days (kidney) to 17.3 (liver). The probability of a POC event increased with severity of illness. The majority (81.5%) of the POC events had no apparent effect on patients' health (63.6% no effect and 17.9% unknown). POC events were associated with longer length of stay (LOS) and higher costs independent of whether there was a patient health impact. Multiple events during the same hospitalization were associated with the highest impact on LOS and cost. POC events in transplantation occur frequently, more often in sicker patients and, although the majority of POC events do not harm the patient, their effect on resource utilization is significant. [source] Getting Real Performance Out of Pay-for-PerformanceTHE MILBANK QUARTERLY, Issue 3 2008SEAN NICHOLSON Context: Most private and public health insurers are implementing pay-for-performance (P4P) programs in an effort to improve the quality of medical care. This article offers a paradigm for evaluating how P4P programs should be structured and how effective they are likely to be. Methods: This article assesses the current comprehensiveness of evidence-based medicine by estimating the percentage of outpatient medical spending for eighteen medical processes recommended by the Institute of Medicine. Findings: Three conditions must be in place for outcomes-based P4P programs to improve the quality of care: (1) health insurers must not fully understand what medical processes improve health (i.e., the health production function); (2) providers must know more about the health production function than insurers do; and (3) health insurers must be able to measure a patient's risk-adjusted health. Only two of these conditions currently exist. Payers appear to have incomplete knowledge of the health production function, and providers appear to know more about the health production function than payers do, but accurate methods of adjusting the risk of a patient's health status are still being developed. Conclusions: This article concludes that in three general situations, P4P will have a different impact on quality and costs and so should be structured differently. When information about patients' health and the health production function is incomplete, as is currently the case, P4P payments should be kept small, should be based on outcomes rather than processes, and should target physicians' practices and health systems. As information improves, P4P incentive payments could be increased, and P4P may become more powerful. Ironically, once information becomes complete, P4P can be replaced entirely by "optimal fee-for-service." [source] | ||||||||||
