Background:

Weather patterns are well-known to affect human health and behavior and are often arbitrarily blamed for high no-show rates (NSRs). The NSR for outpatient gastrointestinal procedures ranges from 4% to 41% depending on the population and procedure performed. Identifying potential causes will allow for the optimization of endoscopy resource utilization.

Aim:

The aim of this study was to evaluate the effects of a day of the year and weather conditions have on NSRs for outpatient endoscopic procedures at a safety-net hospital in Cleveland, Ohio, United States.

Methods:

A 12-month, retrospective cohort study of the NSR for outpatient endoscopic procedures was performed using local weather data from January 1, 2017 to December 31, 2017. Data was assessed by analysis of variance/t test, and the χ 2 test was used to analyze weather impact on NSR.

Results:

A total of 7935 patients had an average …
