Assessment of drug-related problems in clinical nutrition patients

Medication use in clinical nutrition patients is affected by concomitant disease states and alterations in medication administration and delivery. The purpose of this evaluation was to document the number and type of drug-related problems that occurred and to evaluate the effect pharmacists had on the care of nutrition patients.

Patients were evaluated by a pharmacist who was part of the clinical nutrition team. Drug-related problems were identified and recommendations were made to resolve them. Acceptance of the recommendations and patient outcomes were documented.

After the evaluation of 440 patients, 220 pharmacist interventions were made. Interventions included 35 drug information requests and 185 recommendations made to solve identified drug-related problems in 126 patients. The most frequent drug-related problems were drug interactions (33/185) and untreated indications (24/185). Of 185 recommendations, 166 were accepted, and 19 were accepted with a modification. A total of 132 of 155 recommendations that were accepted or accepted with modification had a positive outcome: 45 patients responded, and 87 patients developed no complications. Six patients did not respond to the recommendation, and in 17 patients the outcome was unknown. Fifty-eight recommendations avoided potential adverse drug events.

Pharmacist intervention identified drug-related problems in almost 30% of clinical nutrition patients. The identification and resolution of the problems had a positive effect on patient care, as indicated by patient outcome and the avoidance of adverse drug events. The drug-related problem approach identified areas in which pharmacists can educate the health care team and ensure proper medication use in this patient population.
