Teaching cardiac auscultation to trainees in internal medicine and family practice: does it work?

BACKGROUND: The general proficiency in physical diagnostic skills seems to be declining in relation to the development of new technologies. The few studies that have examined this question have invariably used recordings of cardiac events obtained from patients. However, this type of evaluation may not correlate particularly well with bedside skills. Our objectives were 1) To compare the cardiac auscultatory skills of physicians in training with those of experienced cardiologists by using real patients to test bedside diagnostic skills. 2) To evaluate the impact of a five-month bedside cardiac auscultation training program. METHODS: 1) In an academic primary care center, 20 physicians (trainees in internal medicine and family practice) and two skilled academic cardiologists listened to 33 cardiac events in 13 patients directly at bedside and identified the cardiac events by completing an open questionnaire. Heart sounds, murmurs and diagnosis were determined beforehand by an independent skilled cardiologist and were validated by echocardiography. Thirteen primary cardiologic diagnoses were possible.2) Ten of the physicians agreed to participate in a course of 45-minute sessions once a week for 5 months. After the course they listened again to the same patients (pre/post-interventional study). RESULTS: 1) The experts were the most skillful, achieving 69% recognition of heart sounds and murmurs and correct diagnoses in 62% of cases. They also heard all of the diastolic murmurs. The residents heard only 40% of the extra heart sounds and made a correct diagnosis in 24% of cases. 2) After the weekly training sessions, their mean percentage for correct diagnosis was 35% [an increase of 66% (p < 0.05)]. CONCLUSIONS: The level of bedside diagnostic skills in this relatively small group of physicians in training is indeed low, but can be improved by a course focusing on realistic bedside teaching.

Is it really worth the effort to renounce to 5 mm trocars?

Objective: Single port laparoscopy andNOTES aim at decreasing the number¦of trocars, at a price of increased technical difficulty and cost, without until now¦any proof of benefit for the patient.Morbidity related to 5 mm trocar sites (TS)¦is claimed to be low, but there are no good quality data on this topic. The aim¦of the present prospective study is to measure the morbidity and overall specific¦impact related to the 5 mm TS and compare them to larger TS.¦Methods:Wecollected prospectively data on 300 consecutive patients operated¦by laparoscopy in our institution between 2009 and 2010. Pain, morbidity,¦cosmetic, and overall patient discomfort were assessed specifically for each¦TS, using standardized questionnaires, at 3 time points: at discharge from¦the hospital, at 1 month and at 6 months after surgery. Results were compared¦between 5 mmand larger TS (10 mm, 12 mmand 15 mm).Trocar sites replaced¦by a minilaparotomy or a stoma were excluded from analysis. In this study we¦present the short-term results.¦Results: Three-hundred patients (mean age 47·5, women 55%) were operated¦with 1074 TS of which 477(44%) were 5 mm TS. Indication to laparoscopy was¦cholecystectomy (31·3%), appendectomy (26·6%), upper GI surgery (16·3%),¦colon resection (13·3%) or other (12·3%). Follow-up at 1 month was completed¦in 90%.¦The 5 mm TS had an infection rate of 0·2%, and a hematoma rate of 1·7%.¦VAS pain scores at the 5mm TS were ≤3 in 91·6% at rest and in 75·9% upon¦effort at discharge, and in 97% at 1 month. Median patient scar assessment¦score (PSAS) of the 5 mm TS at 1 month was 6 (IQR: 2-9) out of 60 (0 =¦best score). Overall discomfort of the 5 mm TS in a VAS scale was 0 in 77%¦and ≤3 in 95% of patients at 1 month. Morbidity, pain assessments, PSAS, and¦overall discomfort scores were all significantly better for 5 mm TS compared to¦larger TS.¦Conclusion: Morbidity, pain, cosmetic impact and overall patient's discomfort¦related to a 5 mm trocar site is extremely low. For this reason, any potential¦advantage related to omitting 5 mm trocars to perform the same type of surgery¦will be difficult to demonstrate.
