“No show” appointment status was modeled as the measure of poor adherence to HIV primary care appointments. All “arrived” and “no show” visits from all study participants during the study period were included in these analyses. “Cancelled” visits, appointments not attended for which a patient notified the clinic they would miss the visit or was hospitalized, were excluded.
Binomial generalized estimating equation (GEE) models with an auto-regressive correlation structure, which accounts for the correlation of multiple observations nested within each patient. Adjusted model controls for other variables with numeric values displayed in the table.
Odds ratio for 10-years increments
The missed visit proportion (MVP) is a binomial ratio of the number of “no show” visits divided by the overall number of scheduled appointments (“arrived” and “no show”) during the study period.
