Impact of clinical pharmacy services on stress ulcer prophylaxis prescribing and related cost in patients with renal insufficiency

Abstract

Abstract Objectives Compared to the general population, chronic kidney disease patients are more vulnerable to gastrointestinal haemorrhage and its morbidity and mortality. Due to the fear of gastrointestinal bleeding consequences in these patients on the one hand, and the perception of general safety of acid suppressive medications on the other hand, inappropriate stress ulcer prophylaxis (SUP) seems to be encountered in nephrology wards. The objectives of this study were to evaluate appropriateness of acid suppression therapy in kidney disease patients and to assess the role of clinical pharmacists to decrease inappropriate SUP prescribing and related costs for these patients. Methods All inpatients at nephrology wards of a teaching hospital were assessed regarding appropriate SUP prescribing during a 6-month pre-intervention phase of the study without any clinical pharmacists' involvement in patients' management. Thereafter, during a 6-month post-intervention phase clinical pharmacists provided local SUP protocol and educational classes for physicians regarding appropriate SUP prescribing and participated actively in the patient-care team. Main findings The results showed significant relative reduction in inappropriate SUP prescribing and related cost in patients with renal insufficiency by about 44% and 67% respectively. Conclusion This study showed that implementing institutional guidelines, and active involvement of clinical pharmacists in the nephrology healthcare team, could reduce inappropriate SUP prescribing and related costs for these patients.
