A strategy to increase appointment keeping in a pediatric clinic.
This paper reports the results of two related studies. The first, a prospective study, investigated the relationship between appointment keeping at a pediatric clinic and parents' self-perceived time utilization skills as measured by a subscale of Wessman's Temporal Experience Questionnaire (TEQ). Using a logistic regression analysis to adjust for the effect of telephone reminders, low scorers on the time utilization subscale were twice as likely as high scorers to miss their appointments. The second study was a test of the value of using knowledge of parents' subjective time perspectives as part of a strategy to increase appointment keeping. The goal of this study was to achieve equivalent missed appointment rates between high and low scorers on the TEQ. Parents attending the clinic were asked to complete the questionnaire, and they were then stratified into two groups. High scorers, those who initially had a low probability of missing appointments, received a single reminder. Low scorers, those who initially had a high probability of missing appointments, received two reminders. Two alternate forms of reminders were randomly allocated within each scoring strata. Equivalent missed appointment rates were observed between parents who scored low and those who scored high on the TEQ. The study also investigated two other questions. Information on the importance of the visit had no effect. Postcard reminders were as effective as telephone reminders and were more cost efficient.
