Toward Improved Implementation of Evidence-based Clinical Algorithms: Clinical Practice Guidelines, Clinical Decision Rules, and Clinical Pathways

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
Gary M. Gaddis MD
This is a summary of the consensus-building workshop entitled "Guideline Implementation and Clinical Pathways," convened May 15, 2007, at the Academic Emergency Medicine Consensus Conference, "Knowledge Translation in Emergency Medicine: Establishing a Research Agenda and Guide Map for Evidence Uptake." A new term, "evidence-based clinical algorithms" is suggested to encompass evidence-based information codified into clinical pathways, clinical practice guidelines, and clinical decision rules. Examples of poor knowledge translation (KT) relevant to the specialty of emergency medicine are identified, followed by brief descriptions of important research and concepts that inform the research recommendations. Four broad themes for research to improve the KT of evidence-based clinical algorithms are suggested: organizational factors, cognitive factors, social factors, and motivational factors. In all cases, research regarding optimizing KT for the subthemes identified by Glasziou and Haynes, "getting the evidence straight," and "getting the evidence used," are interwoven into the thematic research recommendations. Consensus was reached that the majority of research efforts to evaluate means to improve KT need to be centered on the factors that show promise to enhance "getting the evidence used," focused especially on organizational factors.

Validity of Revised Doppler Echocardiographic Algorithms and Composite Clinical and Angiographic Data in Diagnosis of Diastolic Dysfunction

ECHOCARDIOGRAPHY, Issue 10 2006
Kofo O. Ogunyankin M.D.
Background: Commonly used echocardiographic indices for grading diastolic function predicated on mitral inflow Doppler analysis have a poor diagnostic concordance and discriminatory value. Even when combined with other indices, significant overlap prevents a single group assignment for many subjects. We tested the relative validity of echocardiographic and clinical algorithms for grading diastolic function in patients undergoing cardiac catheterization. Method: Patients (n = 115), had echocardiograms immediately prior to measuring left ventricular (LV) diastolic (pre-A, mean, end-diastolic) pressures. Diastolic function was classified into the traditional four stages, and into three stages using a new classification that obviates the pseudonormal class. Summative clinical and angiographic data were used in a standardized fashion to classify each patient according to the probability for abnormal diastolic function. Measured LV diastolic pressure in each patient was compared with expected diastolic pressures based on the clinical and echocardiographic classifications. Result: The group means of the diastolic pressures were identical in patients stratified by four-stage or three-stage echocardiographic classifications, indicating that both classifications schemes are interchangeable. When severe diastolic dysfunction is diagnosed by the three-stage classification, 88% and 12%, respectively, were clinically classified as high and intermediate probability, and the mean LV pre-A pressures was >12 mmHg (P < 0.005). Conversely, the mean LV pre-A pressure in the clinical low probability or echocardiographic normal groups was <11 mmHg. Conclusion: Use of a standardized clinical algorithm to define the probability of diastolic function identifies patients with elevated LV filing pressure to the same extent as echocardiographic methods.

Patterns of care for men with prostate cancer after failure of primary treatment

CANCER, Issue 2 2006
Tracey L. Krupski MD
Abstract BACKGROUND. This study sought to determine trends in patterns of care after failure of primary prostate cancer treatment and to determine whether nonclinical factors influenced the receipt of secondary treatment. METHODS. The authors identified individuals treated for nonmetastatic prostate cancer in the years 1991,1999 from the linked databases of Medicare and the National Cancer Institute's Surveillance, Epidemiology, and End Results registry. The outcome of interest was receipt of secondary therapy. They performed Cox proportional hazard analyses to investigate the link between demographic and clinical characteristics and the likelihood of receiving secondary treatment after either surgery or radiation. RESULTS. Of 65,716 subjects who met our inclusion criteria, 10,200 (15%) received some form of secondary therapy. For men undergoing initial surgical or radiation therapy, tumor grade, year of diagnosis, and geographic region were associated with secondary therapy. No socioeconomic factors such as education, ethnicity, or income level were associated with secondary therapy. CONCLUSIONS. Patterns of care after primary prostate cancer therapy continue to vary regionally. Standardized clinical algorithms and utilization of prostate-specific antigen testing appear to have influenced secondary therapy rates. Cancer 2006. © 2006 American Cancer Society. [source]
