Emergency medical technician schedule modification: impact and implications during short- and long-term follow-up.
OBJECTIVE
To determine whether modifying work schedules from 24- to 12-hour shifts results in favorable improvements across a range of psychological and social variables among emergency medical technicians (EMTs).


METHODS
Sequential (before and after) surveys were completed voluntarily by EMTs at 1 month prior to, 2 months after, and 1 year after a workshift modification (change from 24- to 12-hour shifts). The surveys assessed job satisfaction, occupational burnout, and attitudes toward work schedules. The questionnaires were completed at emergency medical service stations.


RESULTS
Of 70 EMTs in the system, 51 (73%) completed the first 2 stages of this study; 35 (50%) completed all 3 stages. Paired-sample t-tests revealed significant differences between baseline and 2-month posttest scores on the following variables: the Maslach Burnout Inventory: Emotional Exhaustion Scale (less perceived exhaustion at 2 months); the Schedule Attitudes Survey: General Affect (perceived more positive view toward schedule at 2 months); Social/Family Impact (perceived less disruption of social/family life at 2 months); and Composite (less overall disruption in quality of life at 2 months). Statistically significant differences between baseline and 1-year posttest scores were found on the following: Schedule Attitudes Survey: General Affect (more positive view toward schedule at 1 year); Social/Family Impact (less disruption in social/family life at 1 year); and Composite (less overall disruption in quality of life at 1 year).


CONCLUSIONS
Modifying EMTs' work schedules from 24- to 12-hour shifts was associated with improvements in EMTs' general attitudes toward their schedules, less disruption of social and family life, and decreased levels of emotional exhaustion at 2 months after the change. While the improvements in EMTs' attitudes toward their schedules persisted at the 1-year follow-up, the measure of emotional exhaustion returned to baseline.
