Do Emergency Medicine Residents Prefer Resident-initiated or Attending-initiated Feedback?

BACKGROUND: Real-time feedback is crucial to improving physician performance. Emerging theory suggests that learner-initiated feedback may be more effective in changing performance than attending-initiated feedback, but little is known about how residents perceive resident- versus attending-initiated feedback. OBJECTIVES: The primary aim was to determine whether residents' satisfaction varied by learner-versus attending-initiated feedback encounters. We hypothesized that residents would be more satisfied with resident-initiated feedback. METHODS: This was a multicenter study of five emergency medicine residency programs. We developed a milestones-based, real-time feedback intervention that provided behavioral anchors for ED subcompetencies and prompted a feedback discussion. The intervention was implemented at all sites for a 3-month period from March to November 2014. Residents were asked to initiate one card per shift; attendings were also invited to initiate encounters and, in either instance, asked to provide one specific suggestion for improvement. Residents confidentially rated their satisfaction with feedback on a 10-point scale. Reported satisfaction was categorized as "very satisfied" (score of 10) versus "less than very satisfied" (score < 10). Logistic regression was used to assess the difference in satisfaction between resident- versus attending-initiated feedback, and random effects were used to account for the clustering of repeated ratings within resident and by site. RESULTS: A total of 785 cards was collected from five sites. Participation varied by site (range = 21-487 cards per site). Of the 587 cards with both feedback initiator and satisfaction data, 67% (396/587) were resident-initiated, and median satisfaction score was 10 (range = 4-10). There was no difference in the odds of being "very satisfied" by resident- vesus attending-initiated encounters (odds ratio = 1.08, 95% confidence interval = 0.41 to 2.83). CONCLUSIONS: Our results suggest that residents are likely to be as satisfied with self-initiated feedback as attending-initiated feedback. Further research is needed to determine whether resident-initiated feedback is more likely to be incorporated into practice and result in objective performance improvements.

Comparison of severity of illness scoring systems in the prediction of hospital mortality in severe sepsis and septic shock.

BACKGROUND: New scoring systems, including the Rapid Emergency Medicine Score (REMS), the Mortality in Emergency Department Sepsis (MEDS) score, and the confusion, urea nitrogen, respiratory rate, blood pressure, 65 years and older (CURB-65) score, have been developed for emergency department (ED) use in various patient populations. Increasing use of early goal directed therapy (EGDT) for the emergent treatment of sepsis introduces a growing population of patients in which the accuracy of these scoring systems has not been widely examined. OBJECTIVES: To evaluate the ability of the REMS, MEDS score, and CURB-65 score to predict mortality in septic patients treated with modified EGDT. MATERIALS AND METHODS: Secondary analysis of data from prospectively identified patients treated with modified EGDT in a large tertiary care suburban community hospital with over 85,000 ED visits annually and 700 inpatient beds, from May 2007 through May 2008. We included all patients with severe sepsis or septic shock, who were treated with our modified EGDT protocol. Our major outcome was in-hospital mortality. The performance of the scores was compared by area under the ROC curves (AUCs). RESULTS: A total of 216 patients with severe sepsis or septic shock were treated with modified EGDT during the study period. Overall mortality was 32.9%. Calculated AUCs were 0.74 [95% confidence interval (CI): 0.67-0.81] for the MEDS score, 0.62 (95% CI: 0.54-0.69) for the REMS, and 0.59 (95% CI: 0.51-0.67) for the CURB-65 score. CONCLUSION: We found that all three ED-based systems for scoring severity of illness had low to moderate predictive capability. The MEDS score demonstrated the largest AUC of the studied scoring systems for the outcome of mortality, although the CIs on point estimates of the AUC of the REMS and CURB-65 scores all overlap.

Evaluation of a modified early goal-directed therapy protocol.

OBJECTIVES: The study aimed to determine mortality in septic patients 2 years after introduction of a modified early goal-directed therapy (EGDT) protocol and to measure compliance with the protocol. DESIGN: This was an observational study of prospectively identified patients treated with EGDT in our emergency department (ED) from May 2007 through May 2008 and compared with retrospectively obtained data on patients treated before protocol implementation, from May 2004 to May 2005. SETTING: This study was conducted at a large tertiary-care suburban community hospital with more than 85 000 ED visits annually and 700 inpatient beds. PATIENTS: Patients with severe sepsis or septic shock were included in the study. INTERVENTIONS: A modified EGDT protocol was implemented. MEASUREMENTS AND MAIN RESULTS: A total of 216 patients were treated with our EGDT protocol, with 32.9% mortality (95% confidence interval [CI], 26.6%-39.2%); 183 patients (84.7%) had septic shock, with a mortality of 34.4% (95% CI, 28%-41%). Our control group of 205 patients had a 27.3% mortality (95% CI, 21.2%-33.5%), of which 123 had septic shock with a mortality of 43.1% (95% CI, 34%-52%). Early goal-directed therapy protocol compliance was as follows: 99% received adequate intravenous fluids, 99% had a central line, 98% had antibiotics in the first 6 hours, 28% had central oxygen saturation measured, 3.7% received dobutamine, and 19% were transfused blood. CONCLUSIONS: Although we found a trend toward decreased mortality in patients with septic shock treated with EGDT, with an absolute difference of 8.7%, this difference was not statistically significant. Compliance with individual elements of the protocol was variable.

Hyperkalemic distal renal tubular acidosis associated with Rett syndrome.

Renal function was studied in a 7-year-old girl with Rett syndrome (RS) complicated by persistent hyperchloremic hyperkalemic metabolic acidosis. The acidosis was associated with a urine pH above 5.5, positive urinary anion gap and decreased potassium excretion. Plasma renin activity, aldosterone and cortisol levels were normal. Therapy with sodium bicarbonate failed to lower urine pH below 5.5 or increase potassium excretion. Hydrochlorothiazide administration resulted in a fall in urine pH below 5.5 and an increase in potassium excretion as a result of increased distal sodium delivery and increased sodium reabsorption in the distal nephron. We conclude that a voltage-dependent type of derangement in the distal nephron, rather than aldosterone deficiency, is responsible for the impairment in urinary acidification observed in this patient. Early detection of impaired renal acidification in RS may prevent or slow the progression of growth failure.

An outbreak of foodborne botulism associated with food sold at a salvage store in Texas.

Foodborne botulism is caused by potent neurotoxins of Clostridium botulinum. We investigated a large outbreak of foodborne botulism among church supper attendees in Texas. We conducted a cohort study of attendees and investigated the salvage store that sold the implicated foods. We identified 15 cases of botulism (40%) among 38 church supper attendees. Nine patients (60%) had botulinum toxin type A detected in stool specimens. The diagnosis was delayed in 3 cases. Fifteen (63%) of 24 attendees who ate a chili dish developed botulism (relative risk, undefined; P<.001). The chili dish was prepared with "brand X" or "brand Y" frozen chili, "brand Z" canned chili, and hot dogs. An unopened container of brand X chili yielded type A toxin. Brand X chili was purchased at a salvage store where perishable foods were inadequately refrigerated. Our investigation highlights the need to improve clinicians' awareness of botulism. More rigorous and more unannounced inspections may be necessary to detect food mishandling at salvage stores.

Emergence of multidrug-resistant Salmonella enterica serotype Newport infections resistant to expanded-spectrum cephalosporins in the United States.

We describe a field investigation in New England that identified the emergence and epidemiology of new strains of multidrug-resistant Salmonella, Newport-MDRAmpC, and summarize the Center for Disease Control and Prevention's surveillance data for these infections. In Massachusetts, the prevalence of Newport-MDRAmpC among Salmonella serotype Newport isolates obtained from humans increased from 0% (0/14) in 1998 to 53% (32/60) in 2001 (P<.001). In a retrospective case-control study, infection with Newport-MDRAmpC was domestically acquired and was associated with exposure to a dairy farm. Isolates from both humans and cattle had indistinguishable or closely related antibiograms and pulsed-field gel electrophoresis patterns. Nationally, the prevalence of ceftriaxone-resistant Salmonella increased from 0.5% in 1998 to 2.4% in 2001; 85% of the isolates in 2001 were Newport-MDRAmpC, and at least 27 states have isolated these strains from humans, cattle, or ground beef. These data document the widespread emergence of Newport-MDRAmpC strains in the United States and show that the 5-fold increase in the prevalence of Salmonella resistant to expanded-spectrum cephalosporins, between 1998 and 2001, is primarily due to the emergence of Newport-MDRAmpC strains.
