Description:OBJECTIVE
We investigated the association between teammate familiarity and workplace injury in the Emergency Medical Services (EMS) setting.
METHODS
We abstracted a mean of 29-months of shift records and Occupational Safety Health Administration injury logs from 14 EMS organizations with 37 total bases located in four U.S. Census regions. Total teammate familiarity was calculated for each dyad as the total number of times a clinician dyad worked together over the study period. We used negative binomial regression to examine differences in injury incidence rate ratios (IRR) by familiarity.
RESULTS
We analyzed 715,826 shift records, representing 4,197 EMS clinicians and 60,701 unique dyads. We determined the mean shifts per dyad was (5.9, SD 19.7), and quartiles of familiarity were 1 shift worked together over the study period, 2–3 shifts, 4–9 shifts, and ≥10 shifts worked together. More than half of all dyads worked one shift together (53.9%, n=32,739), 24.8% of dyads 2–3 shifts, 11.8% worked 4–9 shifts, and 9.6% worked ≥10 shifts. The overall incidence rate of injury across all organizations was 17.5 per 100 FTE, range 4.7 to 85.6 per 100 FTE. The raw injury rate was 33.5 per 100 FTEs for dyads with one shift of total familiarity, 14.2 for 2–3 shifts, 8.3 for 4–9 shifts, and 0.3 for ≥10 shifts. Negative binomial regression confirmed that dyads with ≥10 shifts had the lowest incidence of injury (IRR=0.03; 95%CI 0.02–0.04).
CONCLUSIONS
Familiarity between teammates varies in the EMS setting, and less familiarity is associated with greater incidence of workplace injury.
