Interruptions in community pharmacies: Frequency, sources, and mitigation strategies.

Background: Interruptions constitute a key part of the communication strategy for healthcare providers, including community pharmacy personnel. Previous research in other healthcare environments has shown that interruptions are very common and may present as patient safety hazards. One 1999 study, conducted in community pharmacy settings, found that interruptions were prevalent and associated with dispensing errors. In the last 20 years, pharmacies have expanded patient services and implemented new technology. Yet, it is unknown how these changes have affected interruption sources and frequency.

Objective: The objective was to characterize the frequency and sources of pharmacist task interruptions that occur in community pharmacies.

Methods: A cross-sectional qualitative study design was used to evaluate the frequency and sources of pharmacist task interruptions in Wisconsin community pharmacies. The participants included 9 pharmacists and 9 technicians working in 2 independently-owned, 2 mass merchandise, and 2 hospital/clinical-affiliated pharmacies.

Results: Interruption rates ranged from 3 to 7 per hour across the 6 pharmacies. Sources of interruptions included: patients, technicians, self-initiated interruptions, technology used in the pharmacy, and a second pharmacist.

Conclusions: Interruptions are common in community pharmacies and the causes are multifactorial. Prudent management of interruptions in these work environments may involve improved technician training and better designs of pharmacy technology.
