Analysis of Prehospital Scene Times and Interventions on Mortality Outcomes in a National Cohort of Penetrating and Blunt Trauma Patients.

BACKGROUND: Recent studies have suggested improved outcomes in victims of penetrating trauma managed with shorter prehospital times and limited interventions. The purpose of the current study was to perform an outcome analysis of patients transported following penetrating and blunt traumatic injuries. METHODS: We performed a descriptive retrospective analysis of the 2014 National Emergency Medical Services Information System (NEMSIS) public release research data set for patients presenting after acute traumatic injury. RESULTS: A total of 2,018,141 patient encounters met criteria, of which 3.9% were penetrating trauma. Prehospital cardiac arrest occurred in 0.5% blunt and 4.2% penetrating trauma patients. Emergency department (ED) mortality was higher in penetrating than blunt trauma patients (4.1% vs. 0.8%). Scene times were 18.1 ± 36.5 minutes for blunt and 16.0 ± 45.3 minutes for penetrating trauma. Mean scene time for blunt trauma patients who died in the ED was 24.9 ± 58.0 minutes compared with 18.8 ± 38.5 minutes for those admitted; for penetrating trauma, scene times were 17.9 ± 23.5 and 13.4 ± 11.6 minutes, respectively. Mean number of procedures performed for blunt trauma patients who died in the ED was 6.5 ± 4.3 compared with 3.1 ± 2.3 for those who survived until admission; for penetrating trauma, the numbers of procedures performed were 5.7 ± 3.4 and 2.6 ± 2.0, respectively. CONCLUSIONS: Although less frequent than blunt trauma, penetrating trauma is associated with significantly higher prehospital and ED mortality. Increased scene time and number of procedures was associated with greater mortality for both blunt and penetrating trauma. Further study is required to better understand any causal relationships between prehospital times and interventions and patient outcomes.

Time Motion Analysis: Impact of Scribes on Provider Time Management.

BACKGROUND: Scribes are unlicensed professionals trained in medical data entry. Limited data exist on the impact of scribes on provider time management in the emergency department (ED). Time-motion analysis is a tool utilized in business to capture detailed movements and durations to task completion. It offers a means to categorize how providers allocate their time during a clinical shift. OBJECTIVE: Evaluate the impact of scribes on how ED providers spend their time. METHODS: A prospective observational study was conducted to assess scribe impact on provider time utilization. Four research assistants (RAs) observed attending providers on 24 8-h control shifts (without a scribe), and 24 scribed shifts. RAs observed and categorized provider activity. Providers self-reported after-hours documentation times. Two-sample t-tests were used for normally distributed data, and Wilcoxon rank-sum tests were used for skewed data. All tests were two-sided, and p-values < 0.05 were considered statistically significant. RESULTS: Scribes decreased total documentation time both on shift (mean 55.3 vs. 36.4 min, p < 0.001) and post shift (mean 42.5 vs. 23.3 min, p = 0.038). They did not significantly decrease the amount of time spent reviewing the medical records or placing orders, nor did they have an impact on provider time spent at patients' bedside or time spent discussing patient care with team members. CONCLUSION: The presence of scribes decreased provider documentation time but did not change the amount of time spent at the bedside or communicating with other team members. Scribes may be a potential strategy to decrease the clerical burden.
