AIM To organize post-procedure satisfaction data into a useful reference and analyze patient-centered parameters to find trends that influence patient satisfaction.METHODS A robust database of two cohorts of outpatients that underwent an endoscopic procedure at Georgetown University Hospital at two separate three-month intervals ranging from November 2012 to January 2013 and November 2015 to January 2016 was compiled.Time of year was identical to control for weather/seasonal issues that may have contributed to the patient experience.The variables recorded included age,sex,body mass index(BMI),type of procedure,indication for procedure,time of the procedure,length of the procedure,type of prep used,endoscopist,satisfactory score,and comments/reasons for score.For continuous variables,differences in averages were tested by two sample t-test,Wilcoxon rank sum test,and ANOVA as appropriate.For categorical variables,differences in proportions between two groups were tested byχ2 test.Correlation test and linear regression analyses were conducted to examine relationships between length of procedure and continuous predictors.A P value<0.05 used to indicate statistically significant relationship.RESULTS The primary outcome of this study was to assess if telephone outreach after an endoscopic intervention was a satisfactory method of obtaining post-procedure satisfaction scores from patients at a tertiary care center.With the addition of post-procedure calls,instilled in January 2014,the response rate was 40.5%(508/1256 patients)from a prior completion rate of 3.4%(31/918)with the mail out survey initially.There was a statistically significant improved response rate pre and post intervention with P<0001.The secondary outcome of this study was to assess if we could use predictive analytics to identify independent predictors of procedure length,such as gender,age,type of procedure,time of procedure,or BMI.The combined pre and post intervention data was used in order to optimize the power to identify independent predictors o
