[Place of clinical pharmacist in the management of drugs in patients with hypertension]

Abstract

Purpose: To synthesize pharmacists' interventions made in the department of internal medicine and hypertension of university hospital of Toulouse and assess the impact on medication orders.

Methods: This is a single-center, prospective study using pharmacists' interventions recorded between September 2013 and March 2014 on the Act-IP(©) website of the French Society of Clinical Pharmacy. The clinical pharmacist is present everyday in the unit to establish the medication reconciliation of new patients (the process of comparing a patient's medication orders to all of the medications that the patient has been taking), and analysis of medication orders. When a risk of iatrogenic drug is identified, a therapeutic change is proposed to the prescriber.

Results: A total of 2491 medication orders were analyzed for 7 months, leading to 39 pharmacists' interventions (1.6 pharmacists' interventions per 100 medication orders). The most commonly identified drug-related problems were improper administration (33%, n=13), not prescribed drug (21%, n=8), non-conformity to guidelines (18%, n=7), supratherapeutic dose (15%, n=6), and 13% (n=5) targeted prescribed treatment not administered, underdosing, incorrect administration or drug interaction. The most relevant molecules were atorvastatin (10%), bromazepam (8%) and levothyroxine (8%) and only 2 interventions targeted antihypertensive drugs. The rate of physicians' acceptance was 92%.

Conclusion: Pharmacists' interventions mainly concern the co-prescriptions of antihypertensive drugs and very few antihypertensive drugs. The clinical pharmacist contributes to preventing iatrogenic in patients with hypertension with a very good acceptance by the clinician.
