Evaluation of written prescription information provided in community pharmacies: a study in eight states

Abstract

Objectives: To develop three tools for assessing the quality of written information provided with new prescriptions in community pharmacies and to identify pharmacy, pharmacist, and patient characteristics associated with the dissemination and quality of that information.

Design: Observational study. Regression techniques were used to analyze the influence of pharmacy, pharmacist, and shopper (acting as patient) characteristics on outcome measures.

Participants: Trained shoppers (acting as patients) visited 306 randomly selected pharmacies in 8 states. Each shopper presented three prescriptions, answered questions according to a standard scenario, accepted the information offered, and paid for the prescriptions.

Main outcome measures: Percentage of shoppers receiving any written information; quality of written information as judged by an expert panel using explicit criteria.

Results: Shoppers received an information leaflet with 87% of the 918 prescriptions dispensed. Although most leaflets provided unbiased information, leaflet length and quality of information varied greatly. A majority of leaflets did not include adequate information about contraindications, precautions, and how to avoid harm. Shoppers were more likely to receive leaflets in chain pharmacies and pharmacies with more staff. Information quality also was higher in chain pharmacies. Shopper and pharmacist demographic characteristics were unrelated to the level or quality of written information after controlling for other factors.

Conclusion: The provision of patient leaflets is becoming a routine practice in the states studied. However, most leaflets do not meet quality criteria. It is important for pharmacists to become familiar with criteria for evaluating these leaflets and to take necessary action to improve their quality.
