BACKGROUND:Quality improvement (QI) initiatives reduce medical errors and are an important aspect of resident physician training. Many institutions have limited funding and few QI experts, making it essential to develop effective programs that require only modest resources. We describe a resident-led, hospitalist-facilitated limited root cause analysis (RCA) QI program developed to meet training needs and institutional constraints. METHODS:We initiated a monthly quality improvement conference (QIC) at the Mount Sinai Hospital in New York City, New York. Before each conference, a third-year resident investigated a patient care issue and completed a limited RCA. At the QIC, the findings were presented to the Internal Medicine residents, followed by a chief resident and hospitalist-facilitated group discussion. All proposed interventions were recorded, and selected interventions were later implemented. The success of these interventions in achieving permanent system-wide change or resident behavior change was tracked. Residents' views on the conferences were solicited via an anonymous questionnaire. RESULTS:Twenty conferences were held over the first 22 months of the program. Twenty-five (54%) of the 46 suggested interventions were initiated. Eighteen (72%) attempted interventions resulted in system-wide change or resident behavior change. Fifty-three residents evaluated the quality of the conferences. The majority believed the conferences were high quality (98%) and led to patient care improvements (96%). CONCLUSIONS:Resident-led modified RCAs are an effective method of integrating QI efforts into resident training. As front line providers, residents are uniquely positioned to identify and implement system changes that benefit patients. Conferences were implemented without overburdening facilitators or participants.

BACKGROUND:Clinical prediction rules (CPR) are tools that clinicians can use to predict the most likely diagnosis, prognosis, or response to treatment in a patient based on individual characteristics. CPRs attempt to standardize, simplify, and increase the accuracy of clinicians' diagnostic and prognostic assessments. The teaching tips series is designed to give teachers advice and materials they can use to attain specific educational objectives. EDUCATIONAL OBJECTIVES/OBJECTIVE:In this article, we present 3 teaching tips aimed at helping clinical learners use clinical prediction rules and to more accurately assess pretest probability in every day practice. The first tip is designed to demonstrate variability in physician estimation of pretest probability. The second tip demonstrates how the estimate of pretest probability influences the interpretation of diagnostic tests and patient management. The third tip exposes learners to various examples and different types of Clinical Prediction Rules (CPR) and how to apply them in practice. PILOT TESTING: We field tested all 3 tips with 16 learners, a mix of interns and senior residents. Teacher preparatory time was approximately 2 hours. The field test utilized a board and a data projector; 3 handouts were prepared. The tips were felt to be clear and the educational objectives reached. Potential teaching pitfalls were identified. CONCLUSION/CONCLUSIONS:Teaching with these tips will help physicians appreciate the importance of applying evidence to their every day decisions. In 2 or 3 short teaching sessions, clinicians can also become familiar with the use of CPRs in applying evidence consistently in everyday practice.

BACKGROUND:Cases of early-onset Alzheimer disease (AD) with an autosomal dominant inheritance pattern (familial AD [FAD]) are rare but have greatly advanced our understanding of the molecular pathogenesis of AD. We describe herein a kindred with very early-onset FAD (age, <40 years) with unusual pathological features and a novel mutation in the presenilin 1 (PSEN1) gene (S170F) and review the existing literature on very early-onset FAD. OBJECTIVE:To analyze the neuropathological and genetic features of a family with onset of AD in the third decade of life. DESIGN, SETTING, AND PARTICIPANTS/METHODS:The proband underwent full clinical assessment and postmortem examination at the Washington University Alzheimer's Disease Research Center, St Louis, Mo. Limited pathological samples and autopsy records of 2 affected family members were available. The proband underwent screening for mutations in genes linked with FAD. RESULTS:Dementia developed in 3 family members in this kindred at a mean age of 27 years; the proband had myoclonus, seizures, and rigidity, similar to findings in previously described kindreds with PSEN1 mutations. All 3 family members were confirmed to have AD by neuropathological examination. The proband also had widespread Lewy body pathology in the brainstem, limbic areas, and neocortex; specific staining for Lewy bodies was not performed in the other 2 family members. The proband had a single mutation (S170F) in exon 6 of the PSEN1 gene, which segregates with disease. CONCLUSIONS:A novel PSEN1 mutation causes very-early-onset FAD with associated Lewy bodies. To our knowledge, this kindred has the earliest reported onset of pathologically confirmed FAD and dementia with Lewy bodies.
