Does the Proportion of Same-Day and 24-Hour Appointments Impact Patient Satisfaction?

Background: The relationship between open access and patient satisfaction is mixed. Our study is the first to assess the relationship between open access appointment scheduling and patient satisfaction in the Military Health System (MHS). It is also unique in that we examine both same-day and 24-hour access through a relationship with satisfaction. Methods: We conducted a panel time-series analysis with general estimating equations on the Army population of outpatient facilities (N = 32), with 32 364 957 total observations. Our primary independent variables were the proportion of a facility’s appointments within 24 hours and same day from July 2013 to May 2015. Results: We identified that a higher proportion of same-day appointments is associated with increased patient satisfaction with the ability to see their provider when needed. We did not find the same result when examining access within 24 hours. Conclusions: Open access appointment scheduling appears to have a greater impact on patient satisfaction with timeliness of care if that appointment is made the same day the patient presents to the facility. Facilities should consider opening more of their schedule to accommodate same-day appointments. This can result in less costly primary care instead of emergency department usage
