RESUMO
BACKGROUND: Evaluate the misuse of proton pump inhibitors (PPIs) in geriatric long-term care (LTC) patients and improve caregiving by de-prescribing non-relevant PPIs in this population. AIM: This study was conducted in the long-term care department of the geriatric hospital Pierre-Garraud in Lyon. All patients receiving PPI for more than 8 weeks were included. A reassessment form was filled to evaluate the treatment benefit/risk ratio during a collegial consultation between the patient's referring physicians and pharmacists. During these consultations, the following possible decisions were taken: continuation, dose adjustment or gradual discontinuation of treatment. Patients' monitoring were performed one month and three months after discontinuation to detect any relapses and causes. RESULTS: Among the 113 patients included, 97 patients had their treatment re-evaluated by collegial consultation. Forty-four (45.4%) patients were treated in accordance with recommendations. For 24 of them, the indication was symptomatic recurrent gastroesophageal reflux disease. The treatment of more than half of the re-evaluated patients (54.6%) was gradually stopped. After the 3-month follow-up post-discontinuation, excluding patients who died during this period, 80.9% of the discontinuations were well-tolerated and only nine were resumed (19.1%). CONCLUSION: This study allowed a re-evaluation of PPI treatments in a high-risk population and offered a decision support tool focused on the benefit/risk balance of PPIs; 55% of treatments were considered irrelevant and could be stopped with 80% of good tolerance.
