Resources Assessment for Penicillin Allergy Testing Performed by Pharmacists at the Patient's Bedside.

BACKGROUND: False penicillin allergies lead to increased antimicrobial resistance, adverse effects, and health care costs by promoting the use of broad-spectrum antibiotics. The Infectious Diseases Society of America recommends the implementation of allergy testing. OBJECTIVES: The primary objective of this research was to estimate the number of pharmacist full-time equivalents (FTEs) required for an intervention aimed at determining penicillin allergy in hospitalized patients. Acceptance of pharmacists' suggestions on antibiotic therapy are described. METHODS: A quasi-experimental study was conducted in a 712-bed university hospital involving hospitalized patients with a suspected penicillin allergy and an infection treatable with penicillin. The time required for the intervention, which included a questionnaire, penicillin allergy testing (skin-prick test, intradermal injection, and oral provocation test), and recommendations on antibiotic therapy were measured to calculate the number of pharmacist FTEs. RESULTS: A total of 55 patients were included. Scarification allergy testing was performed on 37, intradermal allergy test on 33, and oral provocation test on 26 patients. The intervention ruled out penicillin allergy in 26 patients, with no serious adverse effects. The intervention was associated with a median weekly pharmacist FTE of 0.15 (interquartile range = 0.12-0.25). The acceptance of pharmacists' suggestions was high and led to 9 patients being switched to an antibiotic with a narrower spectrum of activity. CONCLUSIONS AND RELEVANCE: This study describes penicillin allergy testing and the number of median weekly hospital pharmacist FTEs required, which was approximately 0.15. These data may aid in the implementation of this safe intervention that promotes narrower-spectrum antibiotherapy.

Does hospitalization influence patients' medication adherence and community pharmacists' interventions?

BACKGROUND: Medication adherence reduces disease morbidity. Data regarding changes in a patient's adherence before and after hospitalization and how this hospitalization influences a pharmacist's interventions are scarce. OBJECTIVE: To assess changes in adherence to cardiovascular and respiratory medications in the year preceding and following a hospitalization; explore patients' perceptions about medication adherence and the pharmacist's role; and describe pharmacists' interventions regarding medication adherence. METHODS: This cohort study included patients hospitalized for acute coronary syndrome, acute worsening of heart failure, or acute COPD exacerbations. Adherence to cardiovascular and respiratory medications was measured by calculating the proportion of days covered (PDC) from prescription refills. Patient interviews were completed to explore their perceptions about medication adherence and the role of the pharmacist. Community pharmacists were invited to complete an online survey and to participate in focus groups to discuss interventions to improve medication adherence. RESULTS: Medication adherence was assessed for 61 patients; the mean PDC was 69.8% 12 months before hospitalization and 72.4% 12 months following hospitalization. Patients reported that they felt the need to take their medications to prevent worsening of their disease. They were satisfied with current pharmaceutical services. A total of 136 questionnaires completed by pharmacists were analyzed and 9 participants attended the focus groups. Most pharmacists reported monitoring prescription renewals to assess adherence, with no significant influence from the hospitalization itself. The patient's interest was reported to be an important facilitator, whereas a lack of time and face-to-face interaction with patients who had their medication delivered to their home was reported a main barrier to interventions. This study was limited by a small sample size. CONCLUSIONS: Patient medication adherence did not significantly change following hospitalization. Hospitalization does not appear to significantly influence patient and pharmacist behavior towards medication adherence.
