The effect of changes in primary attending doctor coverage frequency on orthodontic treatment time and results.

Abstract

To determine whether changes in primary attending (PA) doctor coverage frequency caused an increase in orthodontic treatment time or a decrease in the quality of treatment results in a postgraduate orthodontic clinic. The effect of T1 Peer Assessment Rating (PAR) scores on PA doctor coverage frequency, treatment times, and results was also evaluated. A sample of 191 postorthodontic subjects was divided into three groups based on PA doctor coverage (high, medium, or low). Treatment times, treatment results, and other variables were compared between the three PA coverage groups. Additionally, the sample was divided into three groups based on T1 PAR scores. Attending coverage frequency, treatment times, and results were compared between the T1 PAR groups. No statistically significant differences were found in treatment time (P = .128) or results (P = .052). There were no statistically significant differences in the mean scores for T1 PAR (P = .056), T2 PAR (P = .602), patient age at T1 (P = .747), total appointments (P = .128), missed appointments (P = .177), or cancelled appointments (P = .183). Statistically significant differences were found between the low T1 PAR group and the medium and high T1 PAR groups (attending coverage, P = .008; results, P < .001; treatment time, P = .001). Under the conditions of this study, variations in PA doctor coverage frequency did not lengthen orthodontic treatment or reduce the quality of treatment results. Low T1 PAR scores were associated with less PA coverage, less change in PAR, and shorter treatment times.
