In the present study, 116 clients calling an outpatient cocaine treatment clinic were randomly assigned to intake appointments scheduled either the same day, 1 day, 3 days, or 7 days later. Significantly more subjects scheduled 1 day later attended their intake appointments (72%), compared to those scheduled 3 days (41%) or 7 days (38%) later. Odds ratios indicate that subjects offered intake appointments approximately 24 h following their initial contact are more than four times as likely to attend their intakes as those scheduled later. This accelerated intake procedure allows clinics to reach more patients in need of services.
