Use of web-based data collection to evaluate analgesic administration and the decision for surgery in horses with colic

EQUINE VETERINARY JOURNAL, Issue 4 2005
N. A. WHITE
Summary Reasons for performing study: There is no current veterinary information with regard to data entry on a website. We therefore completed a prospective study on use of analgesics in relation to the need for abdominal surgery using a web-based survey instrument. Objectives: To establish an internet-based data entry system that could be used to record prospective data on horses with colic. Hypothesis: Failure of horses to respond to the initial administration of an analgesic is an indicator of the need for abdominal surgery. Methods: A survey was developed to determine if the response to administration of an analgesic during a veterinarian's first examination of a horse with colic was related to the need for surgery. Veterinarians were contacted via AAEP and ECN listservs requesting submission of cases using a log-in system at a data entry website. The survey was completed by submission of a data entry page. Results: Twenty-seven veterinarians submitted details of 119 cases of colic, 28 of which required surgery. The need for surgery was significantly associated with moderate or severe pain observed during the first examination compared to mild or no pain, and with constant pain or return of pain after administration of one or more analgesics and the need to administer a second analgesic treatment. Abnormal findings on rectal examination were not associated with the need for surgery, whereas total absence or decrease of intestinal sounds was significantly related to the odds that surgery was needed. The web-based data collection was successful in collecting all data points on the survey for each case. Conclusions: This study reinforced veterinarians' use of response to therapy as a way to determine the need for abdominal surgery. Potential relevance: When a specific diagnosis has not been made, lack of response or resumption of colic after analgesic administration should be considered as an indicator of the need for surgery. Web-based collection of data allows veterinary practitioners to participate in clinical research by providing prospective data. [source]


Dihydropyridine- and voltage-sensitive Ca2+ entry in human parathyroid cells

EXPERIMENTAL PHYSIOLOGY, Issue 7 2009
Keitaro Yokoyama
Patch-clamp and fluorescence measurements of cytoplasmic Ca2+ concentration ([Ca2+]i) were performed to directly detect extracellular Ca2+ entry into cultured parathyroid cells from patients with secondary hyperparathyroidism. Cells loaded with fluo-3 AM or fluo-4 AM showed a transient increase in fluorescence (Ca2+ transient) following 10 s exposure to 150 mm K+ solution in the presence of millimolar concentrations of external Ca2+. The Ca2+ transient was completely inactivated after 30,40 s exposure to the high-K+ solution, was reduced by dihydropyridine antagonists and was enhanced by FPL-64176, an L-type Ca2+ channel agonist. The electrophysiological and pharmacological properties of the whole-cell Ca2+ and Ba2+ currents were similar to those of L-type Ca2+ channels. The Ca2+ transients induced by 10 s exposure to 3.0 mm extracellular Ca2+ concentration ([Ca2+]o) were inhibited by dihydropyridine antagonists and were partly inactivated following 30,40 s exposure to the high-K+ solution. These results demonstrate, for the first time, that human parathyroid cells express L-type-like Ca2+ channels that are possibly involved in the [Ca2+]o -induced change in [Ca2+]i. This Ca2+ entry system might provide a compensatory pathway for the negative feedback regulation of parathyroid hormone secretion, especially in hyperplastic conditions in which the Ca2+ -sensing receptor is poorly expressed.

Central venous access for haemodialysis: prospective evaluation of possible complications

JOURNAL OF CLINICAL NURSING, Issue 2 2007
Denise De Andrade PhD
Aims and objectives., The combination of chronic renal insufficiency and haemodialysis represents a challenge for health professionals. Chronic renal insufficiency patients undergoing haemodialysis treatment through a temporary double-lumen catheter were prospectively studied in order to identify the type and frequency of local and systemic complications. Methods., A six-month period was established with a view to the inclusion of new cases. Data were acquired through interviews, clinical assessment and patient records, and entered into a Microsoft Excel database through a double entry system and exported to the Statistical Package Social Sciences software. Sixty-four patients were evaluated prospectively, of which thirty-eight (59.4%) were men and 35 (54.7%) required catheter insertion for immediate treatment. During the study period, 145 catheters were inserted, ranging from 1 to 7 implants per patient, 29 (45.3%) were single insertions and 127 (87.6%) catheters were inserted into the jugular vein. The catheters were left in place for an average of 30 days. Results., Forty-one (64%) presented inadequate functioning, after about 26 days. A febrile state occurred in 24 (37.5%) patients after 34 days, secretion at the catheter entry site in 27 (42.2% after 26 days and bloodstream infection was encountered in 34(53%) after 34 days. Of the 61 blood culture samples, thirty (49%) were positive for Staphylococcus aureus that was the microorganism most frequently isolated. Conclusion., The findings indicate worrying aspects such as the catheters permanence time, exposing patients to different complications, including infection. Furthermore, inadequate catheter functioning leads to inefficient haemodialysis treatment. Relevance to clinical practice., Knowledge about complications allows for systematic care planning, prevention and control actions. [source]


Oral quinolones in hospitalized patients: an evaluation of a computerized decision support intervention,

JOURNAL OF INTERNAL MEDICINE, Issue 4 2004

Abstract. Objective., To determine whether a computerized decision support system could increase the proportion of oral quinolone antibiotic orders placed for hospitalized patients. Design., Prospective, interrupted time-series analysis. Setting., University hospital in the south-eastern United States. Subjects., Inpatient quinolone orders placed from 1 February 2001 to 31 January 2003. Intervention., A web-based intervention was deployed as part of an existing order entry system at a university hospital on 5 February 2002. Based on an automated query of active medication and diet orders, some users ordering intravenous quinolones were presented with a suggestion to consider choosing an oral formulation. Main outcome measure., The proportion of inpatient quinolone orders placed for oral formulations before and after deployment of the intervention. Results., There were a total of 15 194 quinolone orders during the study period, of which 8962 (59%) were for oral forms. Orders for oral quinolones increased from 4202 (56%) before the intervention to 4760 (62%) after, without a change in total orders. In the time-series analysis, there was an overall 5.6% increase (95% CI 2.8,8.4%; P < 0.001) in weekly oral quinolone orders due to the intervention, with the greatest effect on nonintensive care medical units. Conclusions., A web-based intervention was able to increase oral quinolone orders in hospitalized patients. This is one of the first studies to demonstrate a significant effect of a computerized intervention on dosing route within an antibiotic class. This model could be applied to other antibiotics or other drug classes with good oral bioavailability. [source]


The diagnostic utility of magnetic resonance imaging in spondylarthritis: An international multicenter evaluation of one hundred eighty-seven subjects

ARTHRITIS & RHEUMATISM, Issue 10 2010
Ulrich Weber
Objective To systematically assess the diagnostic utility of magnetic resonance imaging (MRI) to differentiate patients with spondylarthritis (SpA) from patients with nonspecific back pain and healthy volunteers, using a standardized evaluation of MR images of the sacroiliac joints. Methods Five readers blinded to the patients and diagnoses independently assessed MRI scans (T1-weighted and STIR sequences) of the sacroiliac joints obtained from 187 subjects: 75 patients with ankylosing spondylitis (AS; symptom duration ,10 years), 27 patients with preradiographic inflammatory back pain (IBP; mean symptom duration 29 months), 26 patients with nonspecific back pain, and 59 healthy control subjects; all participants were age 45 years or younger. Bone marrow edema, fat infiltration, erosion, and ankylosis were recorded according to standardized definitions using an online data entry system. We calculated sensitivity, specificity, and positive and negative likelihood ratios (LRs) for the diagnosis of SpA based on global assessment of the MRI scans. Results Diagnostic utility was high for all 5 readers, both for patients with AS (sensitivity 0.90, specificity 0.97, positive LR 44.6) and for patients with preradiographic IBP (sensitivity 0.51, specificity 0.97, positive LR 26.0). Diagnostic utility based solely on detection of bone marrow edema enhanced sensitivity (67%) for patients with IBP but reduced specificity (88%); detection of erosions in addition to bone marrow edema further enhanced sensitivity (81%) without changing specificity. A single lesion of the sacroiliac joint on MRI was observed in up to 27% of control subjects. Conclusion This systematic and standardized evaluation of sacroiliac joints in patients with SpA showed that MRI has much greater diagnostic utility than has been documented previously. We present for the first time a data-driven definition of MRI-visualized positivity for SpA. [source]


Strategies to reduce medication errors with reference to older adults

INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2006
Brent Hodgkinson BSc (Hons) MSc GradCertPH GradCertEcon(Health)
Abstract Background, In Australia, around 59% of the general population uses prescription medication with this number increasing to about 86% in those aged 65 and over and 83% of the population over 85 using two or more medications simultaneously. A recent report suggests that between 2% and 3% of all hospital admissions in Australia may be medication related with older Australians at higher risk because of higher levels of medicine intake and increased likelihood of being admitted to hospital. The most common medication errors encountered in hospitals in Australia are prescription/medication ordering errors, dispensing, administration and medication recording errors. Contributing factors to these errors have largely not been reported in the hospital environment. In the community, inappropriate drugs, prescribing errors, administration errors, and inappropriate dose errors are most common. Objectives, To present the best available evidence for strategies to prevent or reduce the incidence of medication errors associated with the prescribing, dispensing and administration of medicines in the older persons in the acute, subacute and residential care settings, with specific attention to persons aged 65 years and over. Search strategy, Bibliographic databases PubMed, Embase, Current contents, The Cochrane Library and others were searched from 1986 to present along with existing health technology websites. The reference lists of included studies and reviews were searched for any additional literature. Selection criteria, Systematic reviews, randomised controlled trials and other research methods such as non-randomised controlled trials, longitudinal studies, cohort or case,control studies, or descriptive studies that evaluate strategies to identify and manage medication incidents. Those people who are involved in the prescribing, dispensing or administering of medication to the older persons (aged 65 years and older) in the acute, subacute or residential care settings were included. Where these studies were limited, evidence available on the general patient population was used. Data collection and analysis, Study design and quality were tabulated and relative risks, odds ratios, mean differences and associated 95% confidence intervals were calculated from individual comparative studies containing count data where possible. All other data were presented in a narrative summary. Results, Strategies that have some evidence for reducing medication incidents are: ,,computerised physician ordering entry systems combined with clinical decision support systems; ,,individual medication supply systems when compared with other dispensing systems such as ward stock approaches; ,,use of clinical pharmacists in the inpatient setting; ,,checking of medication orders by two nurses before dispensing medication; ,,a Medication Administration Review and Safety committee; and ,,providing bedside glucose monitors and educating nurses on importance of timely insulin administration. In general, the evidence for the effectiveness of intervention strategies to reduce the incidence of medication errors is weak and high-quality controlled trials are needed in all areas of medication prescription and delivery.
