Effect of pharmacist interventions in chronic kidney disease: a meta-analysis

Abstract

Background Pharmacists are uniquely placed with their therapeutic knowledge to manage people with chronic kidney disease (CKD). Data is limited regarding the impact of pharmacist interventions on economic, clinical, and humanistic outcomes (ECHO). Methods A systematic review and meta-analysis of randomized controlled trials (RCTs) of interventions with pharmacist input was conducted, which included adults with a diagnosis of CKD, including those with and without kidney replacement therapy. Data was extracted on ECHO: economic (e.g. healthcare-associated costs), clinical (e.g. mortality), and humanistic (e.g. patient satisfaction) outcomes. Where appropriate, a random-effects model meta-analysis generated a pooled estimate of effect. A direction of effect plot was used to summarize the overall effects for clinical outcome domains. Results 32 RCTs reported a total of 10 economic, 211 clinical, and 18 humanistic outcomes. Pharmacist interventions resulted in statistically significant improvements in systolic blood pressure and hemoglobin levels, but not in diastolic blood pressure, estimated glomerular filtration rate, creatinine, and low-density lipoprotein cholesterol levels. Mixed findings were reported for clinical and economic outcomes, whilst pharmacist interventions resulted in an improvement in humanistic outcomes such as patient satisfaction and patient knowledge. Conclusion Findings showed pharmacist interventions had mixed results for various outcomes. Future studies should be more robustly designed and take into consideration the role of the pharmacist in prescribing and deprescribing, the findings of which will help inform research and clinical practice.
