OBJECTIVE: This study was designed to compare, in a primary care
setting, the health care utilization of women who participated in a trauma
research study with the health care utilization of women who did not.
METHOD: Health care utilization in the 12 months before and the 12 months
after participation in trauma research was determined for both participants
(N = 116) and a group of control subjects (N = 100) matched for day of
service. RESULTS: Pairwise t test results indicated that for the women who
participated in the research, all measures of health care utilization
significantly increased in the 12 months after the trauma study; for the
control subjects, only the number of ongoing prescriptions significantly
increased. Sign tests confirmed that a significantly greater number of
research participants demonstrated a positive difference (increase in
utilization) for all health care variables, whereas only ongoing
prescriptions demonstrated a significant systematic increase among control
subjects. CONCLUSIONS: The findings suggest that participation in trauma
research may increase subsequent health care utilization.
