RESUMO
Little information is available regarding the current patterns of medication use in long-term dialysis centers. Therefore, we surveyed the medication records of 1,023 patients undergoing long-term dialysis therapy in 27 dialysis centers. The mean number of medications prescribed per patient was 7.7 +/- 0.54, increasing patient age, increasing duration of dialysis, in-center dialysis, and the presence of underlying diabetic and hypertensive nephropathy were associated with increased frequency of medication use. The use of multiple pharmacologic agents was associated with a high frequency of drug duplication (12%), potential dosage error (9%), potential significant drug interaction (15%), and use of contraindicated drugs (2.5%). A lack of individualization of the use of several pharmacologic agents was apparent. An extreme degree of center variability in drug use was also apparent. Periodic review of medication use should be undertaken in the long-term dialysis setting.
