Abstract

 Introduction. The essential objective of the registry systems is not only establishment of a comprehensive database, but also facilitating and improvement of the quality of patient management through reminding the medical staff of the time of certain evaluations (Questionnaires). Therefore, the response rate of centers to registries could possibly reflect this quality of the patient care. In this article, we are going to evaluate if centers’ response rate has any correlation with patients’ outcome.Methods. Between January 1995 and December 2006, from 26 PD centers, data on 1472 patients including demographic, clinical and laboratory characteristics, which were monthly collected through questionnaires were entered in “Hakim” (a Farsi database) and analyzed using STATA (9.0). The Pediatric centers and centers with less than 20 patients were excluded. In 14 remaining centers, the response rate to 108 questions were computed and the centers’ response rate were categorized as high, low, and average. Cox regression analysis was used to compare patient and technique survival in groups with different percentage of response rate. A P value < 0.05 was considered statistically significant.Results. The highest mean response rate for the 14 centers was 70%, the lowest was 19%, and the average for all centers was 47%. Cox regression analysis showed that patient survival was significantly higher in the center with the highest response rates (HR = 2.65; P = 0.007); similar result was found for technique survival (HR = 3.09; P = 0.004). It was also shown that, patient and technique survival for the centers with average response rate of less than 60% was significantly lower (HR = 1.48, P = 0.002 and HR = 1.98, P = 0.001, respectively). The analyses also showed that the higher patient and technique survival in the center with higher response rate was not due to higher hemoglobin or albumin level and higher number of patients with positive selection or lower age, BMI, systolic blood pressure, diastolic blood pressure, or lower number of diabetic patients in that center (P > 0.05). Conclusion. The quality of patient care and survival might be accessed through the mean level of response rate to questionnaires in centers. Thus, improvement in patient and technique survival could possibly be achieved through medical team education and center instructive programs.
