Treatment related problems in Jordanian hemodialysis patients.

Background Treatment related problems are any event or circumstance involving patient treatment that actually or potentially interferes with an optimum outcome for a patient. Hemodialysis patients have on average 5-6 comorbid conditions and require 8-12 medications each day making them vulnerable to treatment related problems. Objective This study aimed to investigate treatment related problems affecting Jordanian hemodialysis patients, as well as assessing the factors associated with them. Setting Three hemodialysis centers in Jordan. Method A cross sectional multi-centered study was conducted. Direct interviews and patient files were used to collect patient information. A validated data collection form was used. Main outcome measure The average number of treatment related problems per patient. Results 160 patients from three different Jordanian dialysis centers were included. The cohort was 53 ± 15.2 years old, been on dialysis for 5.9 ± 5.3 years, had 3.9 ± 1.8 comorbid conditions and took 10.2 ± 2.8 different medications. There were a total of 1018 treatment related problems, a treatment related problem occurred once every 1.47 drug exposures. Adverse events were the most commonly occurring treatment related problems (27%), followed by indication related errors and dosing errors (24% and 21%, respectively). The number of treatment related problems is positively associated with age, the number of comorbid conditions, the number of hospital admissions in the previous year and the number of medications taken by the patient. Conclusion In the Jordanian hemodialysis population, treatment related problems affect virtually all patients. Most patients suffered adverse drug events and/or had drug indication problems. The number of treatment related problems correlated positively with age and the number of medications taken by the patient. Those with more treatment related problems also had higher hospital admissions and longer admission periods. Serious measures should be made in order to reduce the number of treatment related problems affecting this vulnerable population.
