Cross-checking to reduce adverse events resulting from medical errors in the emergency department: study protocol of the CHARMED cluster randomized study

A novel reflective practice intervention improves quality of care in the emergency department

INTRODUCTION

Most interventions to improve clinical outcomes in the emergency department (ED) are based on structural changes. This study embraced a different strategy and examined the impact of a reflective practice intervention (RPI) on ED quality of care.

METHODS

A pre-post-intervention quasi-experimental nested design was conducted between January 2017 and June 2018 in an Israeli public tertiary academic ED. Nighty-six ED teams (triage and staff nurses and a physician) were included pre and post RPI. Data were collected pre and post RPI at patient-triage nurse encounters using triage-accuracy questionnaires. Time to decision, length-of-stay, and hospitalization and mortality rates were retrieved from the medical charts of 1920 patients (20 per team).

RESULTS

Accurate triage was significantly higher post than pre intervention (4.84 ± 1.45 vs. 3.87 ± 1.48; range 1-7; p < .001), whereas time to decision (253.30 ± 246.75 vs. 304.64 ± 249.14 min), hospitalization rates (n = 291, 30.3% vs. n = 374, 39.0%; p < .001), and hospital length-of-stay (5.73 ± 6.72 vs. 6.69 ± 6.20; p = .04) significantly decreased.

CONCLUSIONS

By adapting organizational reflective practice principles to the ED dynamic environment, the RPI was associated with a significant improvement in ED quality-of-care measures.

Medication safety in emergency medical services: approaching an evidence-based method of verification to reduce errors

Lack of verification is often cited as a root cause of medication errors; however, medication errors occur in spite of conventional verification practices and it appears that human factors engineering (HFE) can inform the design of a more effective method. To this end, an HFE-driven process was designed and implemented in an urban, Midwestern emergency medical service agency. Medication error data were collected over a 54-month period, 27 months before and after implementation. A decrease in the average monthly error rate was realized for all medications administered (49.0%) during the post-intervention time period. The average monthly error rate for fentanyl, a commonly administered analgesic, demonstrated a 71.1% error rate decrease. This study is the first to evaluate the effectiveness of a team-based cross-check process for medication verification to prevent errors in the prehospital setting.

Effect of Systematic Physician Cross-checking on Reducing Adverse Events in the Emergency Department: The CHARMED Cluster Randomized Trial

IMPORTANCE

Emergency departments (ED) are environments that are at high risk for medical errors. Previous studies suggested that the proportion of medical errors may decrease when more than 1 physician is involved.

OBJECTIVE

To reduce the proportion of medical errors by implementing systematic cross-checking between emergency physicians.

DESIGN, SETTING, AND PARTICIPANTS

This cluster randomized crossover trial includes a random sample of 14 adult patients (age ≥18 years) per day during two 10-day period in 6 EDs (n = 1680 patients) in France.

INTERVENTIONS

Systematic cross-checking between emergency physicians, 3 times a day, which included a brief presentation of one physician's case to another, followed by the second physician's feedback to the first.

MAIN OUTCOMES AND MEASURES

Medical error in the ED, defined as an adverse event (either a near miss or a serious adverse event). The primary end point was identified using a 2-level error detection surveillance system, blinded to the strategy allocation.

RESULTS

Among the 1680 included patients (mean [SD] age, 57.5 [21.7] years), 144 (8.6%) had an adverse event. There were 54 adverse events among 840 patients (6.4%) in the cross-check group compared with 90 adverse events among 840 patients (10.7%) in the standard care group (relative risk reduction [RRR], 40% [95% CI, 12% to 59%]; absolute risk reduction [ARR], 4.3%; number needed to treat [NNT], 24). There was also a significant reduction rate of near misses (RRR, 47% [95% CI, 15% to 67%]; ARR, 2.7%; NNT, 37) but not of the rate of preventable serious adverse events (RRR, 29% [95% CI, -18% to 57%]; ARR, 1.2%; NNT, 83).

CONCLUSIONS AND RELEVANCE

The implementation of systematic cross-checking between emergency physicians was associated with a significant reduction in adverse events, mainly driven by a reduction in near misses.
