Hemodialysis patients' noncompliance with oral medications.
The purpose of this study was to describe the prevalence, severity, and patterns of noncompliance with prescribed medications among hemodialysis patients; and to identify patient, disease and/or treatment characteristics associated with noncompliance. Demographic and medical history information were collected from chart reviews and patient interviews. Compliance data were collected via self-report, pill count, and a medication event monitoring system (MEMS, Product of Aprex, a division of Apria Healthcare; Costa Mesa, CA). A total of 135 hemodialysis patients from 11 dialysis facilities in a large Midwestern metropolitan area participated. Overall, medication compliance rates were very low. Of the patient, disease, and treatment characteristics considered, only race was found to be associated with patient noncompliance; African-American patients had higher rates of noncompliance with both monitored medications. The results of this study confirm that noncompliance with medication regimens continues to be an unremitting problem for hemodialysis patients and that demographic, medical history, and treatment characteristics do not adequately explain this behavior. Also, estimates of patient compliance as measured by self-report, pill count, and microelectronic monitoring are disparate enough to suggest that relying exclusively on patients' self-report of compliance might be insufficient.
