Sociodemographic Factors Associated With Decreased Compliance to Prescribed Rehabilitation After Surgical Treatment of Knee Injuries in Pediatric Patients

Background: Rehabilitation is an important component of care in postsurgical knee patients, especially as it pertains to return to preinjury activity level. Despite the established significance of rehabilitation in improving outcomes after certain surgical procedures, there is a lack of investigation into compliance rates and factors that affect compliance in pediatric patients. Purpose/Hypothesis: The purpose of this study was to evaluate sociodemographic factors associated with noncompliance in pediatric patients after knee surgery to characterize health disparities in this population. Our hypothesis was that certain sociodemographic factors would be associated with decreased compliance. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A retrospective review of medical records was used to gather data on compliance rate, demographics, and socioeconomic factors for pediatric patients undergoing rehabilitation after knee surgery. Compliance rate was determined by counting the total scheduled appointments, cancellations, and no-shows (defined as visits for which patients did not show up and did not provide notification of cancellation). Various types of knee injuries were included in this study. Data were evaluated using bivariate analyses in addition to hierarchical linear and binary logistic regression to assess for associations between sociodemographic factors and compliance rate. Results: Our total sample size was 186 patients. When compared with patients from non-single-parent households, patients from single-parent households were found to have a lower rate of physical therapy compliance (72.2% vs 80.1%; P < .001), were less likely to reach the 85% compliance threshold (9.1% vs 42.4%; P < .001), and had an increased amount of cancellations and no-shows (16.7 vs 11.7 visits; P = .02). Although a small sample size, Hispanic/Latino patients were shown to have a lower achievement of the 85% compliance threshold compared with non-Hispanic/Latino patients (0% vs 38.2%; P = .04). Increased distance from the rehabilitation clinic was associated with lower achievement of the 85% compliance threshold (P = .033). Conclusion: Overall, there were several significant demographic and socioeconomic variables associated with rehabilitation compliance, specifically single-parent status, distance to rehabilitation clinic, and ethnicity. These results suggest potential predictors of decreased compliance that warrant prospective investigation.
