Factors Influencing Drug Shortages and Their Resolution in South Korean Community Pharmacies

Purpose

Drug shortages directly affect the final stage in the pharmaceutical supply chain, prescription fulfillment in community pharmacies (CPs). This study investigated the current state of drug shortages, their resolution, and influencing factors within CPs.

Methods

A cross-sectional online survey was conducted among pharmacists working at pharmacies in Seoul between 7 and 31 October 2022. The survey gathered data on pharmacies and pharmacists' characteristics, drug distribution, information, communication, and administrative practices. Logistic regression was used to identify the factors influencing these rates. Regression results are presented as odds ratios (OR) and 95% confidence intervals (CIs).

Results

Of the 1200 pharmacists approached, 713 participated, yielding a response rate of 59.4%. After excluding incomplete responses, data from 671 respondents were analyzed. Pharmacies with higher prescription drug sales demonstrated a lower OR for drug shortages (OR=0.66, 95% CI=0.60-0.72) compared to those with lower sales volumes. Resolution rates were significantly higher when pharmacies were located near clinics (OR=3.30, 95% CI=2.3-4.74) and general hospitals (OR=3.45, 95% CI=2.35-5.07) compared to those without nearby medical facilities. Additionally, good communication with prescribers increased the resolution rates (OR=1.46, 95% CI=1.26-1.69).

Conclusion

This study examines the influence of pharmacy purchasing power on drug shortages, identifying proximity to healthcare facilities and communication with prescribers as factors affecting the resolution rates. These findings provide valuable insights for pharmacists, policymakers, and future researchers to optimize drug supply chain management and mitigate shortages in community settings.

Drug Shortage: Causes, Impact, and Mitigation Strategies

Drug shortage is a global issue affecting low, middle, and high-income countries. Many countries have developed various strategies to overcome the problem, while the problem is accelerating, affecting the whole world. All types of drugs, such as essential life-saving drugs, oncology medicines, antimicrobial drugs, analgesics, opioids, cardiovascular drugs, radiopharmaceutical, and parenteral products, are liable to the shortage. Among all pharmaceutical dosage forms, sterile injectable products have a higher risk of shortage than other forms. The causes of shortage are multifactorial, including supply issues, demand issues, and regulatory issues. Supply issues consist of manufacturing problems, unavailability of raw materials, logistic problems, and business problems. In contrast, demand issues include just-in-time inventory, higher demand for a product, seasonal demand, and unpredictable demand. For regulatory issues, one important factor is the lack of a unified definition of drug shortage. Drug shortage affects all stakeholders from economic, clinical, and humanistic aspects. WHO established global mitigation strategies from four levels to overcome drug shortages globally. It includes a workaround to tackle the current shortage, operational improvements to reduce the shortage risk and achieve early warning, changes in governmental policies, and education and training of all health professionals about managing shortages.
