Methods
A retrospective data analysis was done using patient data collected from January 5, 2004 to January 27, 2005 by the Christiana Care Health System (CCHS) bariatric surgery program. The University of Delaware and CCHS institutional review boards approved the performance of the retrospective data analysis.
The patients selected had completed all the requirements of the preoperative bariatric surgery program and had undergone weight loss surgery. The 375 selected patients had undergone either
Results
The test of the full model with groups 1, 2, 3, and 4 added against a constant-only model was statistically reliable [calculated by chi-square (14, n = 375) = 67.55, P <.001], indicating that the variables, as a set, reliably distinguished between adherence and nonadherence. The model with 4 groups correctly classified 67.8% of the cases of adherence and nonadherence when all 14 predictors were in the model. Table 2 lists the estimates, standard errors, Wald test statistics, odds ratios [exp
Discussion
Of the 14 independent variables used, 5 were statistically significant predictors of a patient's adherence to follow-up care. In group 1, the psychological variables that assessed depression (Beck Depression Inventory) and eating habits (Eating Attitudes Test) were not significant. Our findings related to depression are in contrast to the findings of a meta-analysis of 569 adherence studies that reported depression to be significantly related to adherence [17]. In the present study, depression
Conclusion
Adherence with postoperative appointments has been shown to be associated with improved patient outcomes. We identified 5 significant predictor variables that affect patient adherence to postoperative appointments after bariatric surgery. The predictors that indicated more likely adherence were increasing patient age, being single, and being employed. The predictors that indicated less likely adherence were self-payment for appointments and a greater BMI. Incorporation of the identified
