Improving death certificate completion: a trial of two training interventions.

The death certificate is an important medical document that impacts mortality statistics and health care policy. Resident physician accuracy in completing death certificates is poor. We assessed the impact of two educational interventions on the quality of death certificate completion by resident physicians. Two-hundred and nineteen internal medicine residents were asked to complete a cause of death statement using a sample case of in-hospital death. Participants were randomized into one of two educational interventions: either an interactive workshop (group I) or provided with printed instruction material (group II). A total of 200 residents completed the study, with 100 in each group. At baseline, competency in death certificate completion was poor. Only 19% of residents achieved an optimal test score. Sixty percent erroneously identified a cardiac cause of death. The death certificate score improved significantly in both group I (14+/-6 vs 24+/-5, p<0.001) and group II (14+/-5 vs 19+/-5, p<0.001) postintervention from baseline. Group I had a higher degree of improvement than group II (24+/-5 vs 19+/-5, p<0.001). Resident physicians' skills in death certificate completion can be improved with an educational intervention. An interactive workshop is a more effective intervention than a printed handout.

Death certificate completion: how well are physicians trained and are cardiovascular causes overstated?

PURPOSE: To determine the ability of residents in completing death certificates correctly. METHODS: A total of 4800 residents were asked to complete a survey and cause-of-death statement using a sample case of in-hospital death due to urosepsis, of whom 590 residents (12%) responded. A scoring scale designed based on instructions from the National Association of Medical Examiners and the American College of Pathologists was used to measure responses quantitatively. RESULTS: Overall performance was poor, with only 23% (n = 137) of responses in the optimal scoring range. The average score was influenced significantly by level of residency training, as well as previous experience, prior formal training, and awareness of the guidelines regarding death certificate completion. Optimal scores correlated with level of residency training and prior formal training in death certificate completion, suggesting the benefits of experience and instruction. Forty-five percent (n = 267) of respondents incorrectly identified a cardiovascular event as the primary cause of death. CONCLUSION: The residents in this study demonstrated suboptimal performance in death certificate completion. Cardiovascular events were often incorrectly identified as the primary cause of death. Formal training can improve performance and should be emphasized in medical schools and residencies.

Differential benefits and outcomes of tirofiban vs abciximab for acute coronary syndromes in current clinical practice.

Little comparative data exist for glycoprotein IIb/IIIa inhibitors in acute coronary syndromes (ACS). Two hundred twenty-eight patients were studied: 114 received tirofiban (TI) and 114 received abciximab (AB) for either unstable angina (UA) or myocardial infarction (MI). All patients received aspirin, heparin, and ticlopidine or clopidogrel. Baseline characteristics were similar between the 2 groups for admitting diagnosis (UA vs MI), age, gender, ejection fraction, diabetes mellitus, prior coronary artery disease, prior myocardial infarction (MI), prior bypass surgery, hypertension, congestive heart failure, hyperlipidemia, MI type (Q vs non-Q), or location. Drug administration time (mean) was 13 hours (AB) and 24 hours (TI). All AB was administered in the catheterization laboratory as compared to TI (34% in laboratory and 66% before laboratory). More AB patients received angioplasty or stent (92% vs 80%, p = 0.008) while more TI patients had CABG (10% vs 3%, p = 0.027). In-hospital complications including death, MI, urgent revascularization, cerebrovascular accidents or transient ischemic attacks, and access site bleeding were similar (p = NS). Multivariate predictors of events (odds ratios) were prior coronary artery bypass graft (2.3), diabetes (1.7), and prior percutaneous transluminal coronary angioplasty (1.7), but not the agent used. Over a mean follow-up of 13 months, the individual endpoints of death, MI, revascularization, or hospitalization were similar for both groups. The AB patients had improved freedom from revascularization (100% vs 81%, p = 0.015) in an emergent setting and TI patients had improved freedom from revascularization (93% vs 77%, p = 0.038) with elective procedures. Tirofiban and abciximab appear effective and safe when used for ACS when recommended dosing and precautions are followed. Major adverse outcomes are rare and bleeding complications uncommon.

Complementary roles of color-flow duplex imaging and intravascular ultrasound in the diagnosis of renal artery fibromuscular dysplasia: should renal arteriography serve as the "gold standard"?

OBJECTIVES: The purpose of this study was to compare color-flow duplex imaging (CFDI), intravascular ultrasound (IVUS), and renal arteriography in diagnosing renal artery (RA) fibromuscular dysplasia (FMD) and correlating with the hemodynamic response to balloon angioplasty (BA) in patients with drug-resistant hypertension. BACKGROUND: Renal arteriography is generally regarded as the gold standard for diagnosing RA FMD. The observation that CFDI and IVUS depicted endoluminal abnormalities suggestive of RA FMD in some patients with normal renal arteriograms prompted comparison of these modalities in a consecutive series of patients. METHODS: Twenty hypertensive patients with CFDI suggestive of RA FMD (mid-to-distal flow derangement and velocity augmentation) underwent renal arteriography, IVUS, and BA, with both immediate and long-term blood pressure (BP) response assessment. RESULTS: All patients were women, aged 31 to 86 years (mean 62 years). On IVUS, various endoluminal defects (eccentric ridges; fluttering membranes; spiraling folds) were depicted at locations predicted by CFDI and were uniformly identified at sites where arteriography depicted classic evidence of FMD (8 patients). However, similar defects were detected by IVUS when angiography was borderline (7 patients) or normal (5 patients). Balloon angioplasty eliminated (16 patients) or reduced (4 patients) the IVUS findings and lowered systolic BP in all (mean reduction 53 mm Hg, p < 0.0001). This reduction was maintained during follow-up of 4 to 22 (mean 13) months (mean reduction 44 mm Hg, p < 0.0001), independent of baseline angiographic appearance. CONCLUSIONS: Both CFDI and IVUS depict the blood flow and endoluminal abnormalities of RA FMD. Balloon angioplasty eliminates or improves IVUS findings and produces substantial, sustained BP reduction, an effect that is independent of baseline arteriographic appearance, calling into question the legitimacy of arteriography as the diagnostic gold standard.
