Outpatient Skull Base/Brain Tumor Clinic Visit No-Show Prediction
Introduction: Outpatient patient visit no-shows result in clinic workflow inefficiencies, delayed access to care, and opportunity costs for providers and staff. Early identification of patients likely to no-show could allow for targeted patient outreach or strategic clinic scheduling/overbooking. Predictors of clinic no-show among the skull base/brain tumor patient population have not been previously characterized.
Methods: All outpatient skull base/brain tumor clinic appointment records between 11/1/2017 and 5/1/2022 were extracted from the electronic health record (EHR) at a single institution. Appointments which were cancelled prior to the date of the visit were excluded. The primary outcome was a clinic visit to which a patient did not check in. Predictive covariates included patient demographics and appointment factors. A multivariable logistic regression model was created using a randomly selected training set of 66% of clinic visits. The model was applied to the remaining 33% validation set and predictive performance was assessed using receiver operating characteristic (ROC) analysis.
Results: Among 5,916 total clinic visits, 494 no-shows were identified. Odds ratios with 95% confidence intervals for the predictive value of variables included in the model are depicted in [Fig. 1]. Increased odds of no-show were seen with older age (OR = 1.02, p < 0.01, [Fig. 2]), greater number of prior no-shows (OR = 3.64, p < 0.01 for three or more prior no-shows) and longer lead time (number of days between appointment scheduling and appointment date, OR = 1.0002 per day of lead time, p = 0.04; [Fig. 3]). Categorical variables for marital status, tobacco use, insurance type, EHR mobile app enrollment, and appointment type each had statistically significant associations with no-show. No-show rates were similar across all providers; telehealth visits were not associated with increased rate of no-shows. When applied to the validation set, the model correctly classified 92.1% of visits, including 82.4% of no-shows. The area under the ROC curve was 0.76 ([Fig. 4]).
Conclusion: The predictive model derived from structured data within the EHR accurately predicted clinic no-shows. This model may be used for targeted patient outreach to improve clinic attendance as well as strategic overbooking to improve clinic operational efficiency.
