Getting to the heart of the issue: senior emergency resident electrocardiogram interpretation and its impact on quality assurance events.

OBJECTIVE: Electrocardiogram (ECG) interpretation skills are of critical importance for diagnostic accuracy and patient safety. In our emergency department (ED), senior third-year emergency medicine residents (EM3s) are the initial interpreters of all ED ECGs. While this is an integral part of emergency medicine education, the accuracy of ECG interpretation is unknown. We aimed to review the adverse quality assurance (QA) events associated with ECG interpretation by EM3s. METHODS: We conducted a retrospective study of all ED ECGs performed between October 2015 and October 2018, which were read primarily by EM3s, at an urban tertiary care medical center treating 56,000 patients per year. All cases referred to the ED QA committee during this time were reviewed. Cases involving a perceived error were referred to a 20-member committee of ED leadership staff, attendings, residents, and nurses for further consensus review. Ninety-five percent confidence intervals (CIs) were calculated. RESULTS: EM3s read 92,928 ECGs during the study period. Of the 3,983 total ED QA cases reviewed, errors were identified in 268 (6.7%; 95% CI, 6.0%-7.6%). Four of the 268 errors involved ECG misinterpretation or failure to act on an ECG abnormality by a resident (1.5%; 95% CI, 0.0%-2.9%). CONCLUSION: A small percentage of the cases referred to the QA committee were a result of EM3 misinterpretation of ECGs. The majority of emergency medicine residencies do not include the senior resident as a primary interpreter of ECGs. These findings support the use of EM3s as initial ED ECG interpreters to increase their clinical exposure.

Using the Boston Syncope Observation Management Pathway to Reduce Hospital Admission and Adverse Outcomes.

INTRODUCTION: In an age of increasing scrutiny of each hospital admission, emergency department (ED) observation has been identified as a low-cost alternative. Prior studies have shown admission rates for syncope in the United States to be as high as 70%. However, the safety and utility of substituting ED observation unit (EDOU) syncope management has not been well studied. The objective of this study was to evaluate the safety of EDOU for the management of patients presenting to the ED with syncope and its efficacy in reducing hospital admissions. METHODS: This was a prospective before-and-after cohort study of consecutive patients presenting with syncope who were seen in an urban ED and were either admitted to the hospital, discharged, or placed in the EDOU. We first performed an observation study of syncope management and then implemented an ED observation-based management pathway. We identified critical interventions and 30-day outcomes. We compared proportions of admissions and adverse events rates with a chi-squared or Fisher's exact test. RESULTS: In the "before" phase, 570 patients were enrolled, with 334 (59%) admitted and 27 (5%) placed in the EDOU; 3% of patients discharged from the ED had critical interventions within 30 days and 10% returned. After the management pathway was introduced, 489 patients were enrolled; 34% (p<0.001) of pathway patients were admitted while 20% were placed in the EDOU; 3% (p=0.99) of discharged patients had critical interventions at 30 days and 3% returned (p=0.001). CONCLUSION: A focused syncope management pathway effectively reduces hospital admissions and adverse events following discharge and returns to the ED.

Robot-assisted sialolithotomy with sialendoscopy for the management of large submandibular gland stones.

OBJECTIVES/HYPOTHESIS: The objectives of this study were to describe robot-assisted sialolithotomy with sialendoscopy (RASS) for the management of large palpable hilar submandibular gland (SMG) stones and analyze procedural success and lingual nerve damage following RASS in comparison to the combined transoral sialendoscopic approach. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review was performed on patients with large palpable hilar SMG stones managed with RASS following institutional review board approval. Large stones were defined as ≥5 mm, the upper limit that can be removed via sialendoscopy. Twenty-two patients between January 2012 and June 2014, with mean stone size of 12.3 mm, were identified. Data collected included symptoms of recurrence, postoperative lingual nerve function, and patient satisfaction at a mean follow-up of 14 months. Procedural success was defined as absence of symptom recurrence in conjunction with gland preservation. These measures were compared with the combined approach (CA) outcomes reported in the English literature. RESULTS: Procedural success was 100% (22/22) for our cohort. No patients reported symptoms of lingual nerve damage at follow-up, whereas four patients reported transient lingual nerve paresthesia (mean duration, 2.5 weeks). Mean patient satisfaction was 9.9 out of 10. Literature review identified 135 patients in the CA cohort. Procedural success rate for these patients was 75%, and lingual nerve damage was reported in 2% of patients. CONCLUSIONS: Our study demonstrates the safety and efficacy of RASS in the management of large SMG sialoliths. We attribute this preliminary success of RASS to the enhanced visualization, magnification, and technical advantages of the procedure. LEVEL OF EVIDENCE: 4.
