Analyses with the addition of the included studies in older adults (GOAL) and in younger adults14 trended further toward favoring behavioral interventions, but remained nonstatistically significant (rate ratio 0.52, 95% CI 0.22 to 1.2; 6 studies, 2,255 subjects).

b

Four studies reported data on accidents in adults. Studies were not designed or powered to detect differences in these outcomes. The best available evidence comes from Project TrEAT (N=774),15 which reported outcomes after 48 months of followup. The study found lower numbers of motor vehicle crashes with fatalities (0 vs. 2), motor vehicle crashes with nonfatal injuries (20 vs. 31), and motor vehicle crashes with property damage only (67 vs. 72), that were not statistically significantly different between the intervention and control groups. Two studies (Anderson 1992 and Scott 1990) reported accident scores (from an alcohol-related problems scale), both with endpoint scores numerically favoring the intervention group.16, 17 Neither found a significant change from baseline data for the intervention group or for the control group. One study conducted in Thailand reported alcohol-related accidents (1 in the intervention group and 4 in the control group) and alcohol-related traffic accidents (3 in the intervention group and 5 in the control group).18

Summary effect sizes and data are from Project TrEAT, as it provided the best evidence (due to design, sample size of 774, risk of bias, and duration of followup). For hospitalizations, two smaller studies of shorter duration reported no statistically significant difference between groups for hospitalization outcomes, but Senft and colleagues (N=516) reported a slightly lower percentage of subjects hospitalized in the intervention group than the control group at 24 months that was not significant (21.2% vs. 22.0%, p=0.81) and a trend toward fewer mean hospital days for those hospitalized (4.7 vs. 6.6, p=0.37); Lock and colleagues (N=127) reported no significant difference between groups for hospital inpatient stays. 48-month cost data are from the societal perspective.15, 19

e

Two 12-month studies reported no difference in change in mean life quality scores between the intervention and control groups (0 vs. 0 and -0.3 vs. -0.3).16, 17 A nurse-led intervention (N=127) reported no significant differences between the intervention and control groups at 6 or 12 months for change in SF-12 physical or mental health scores.20
