A multi-site repeated prevalence study of medicine shortages in community pharmacies

Background: Medicine shortages are a global problem. Prior studies have focused on hospitals, and staff views, with less information on community practice. This study aimed to estimate the prevalence of medicine shortages in community pharmacies and potential impact on patients.

Method: Four community pharmacies (two urban, two rural) in Ireland recorded details of prescription request shortages per items dispensed. Data were gathered one study day per month from February to April 2023. A prevalence across sites was estimated and trends examined using a Poisson regression.

Results: There were 76 medicine requests defined as shortages out of 3734 prescription item requests, giving a mean shortage prevalence of 2% (95% CI 1.6-2.5%). There was a non-significant, 17%, increase in shortage rate across the study period (p = 0.256). Higher rates were observed in the two urban pharmacies. In total, 61/76 (80%) of shortages were associated with a delay in patient treatment.

Conclusion: Shortages are prevalent in community pharmacy and cause delays in patient treatment and increase in workload of pharmacy staff. Regulatory initiatives to address the issue at a manufacturer level have been proposed, although workforce planning, resourcing and professional role expansion are also required to protect pharmacy staff and patient outcomes.
