Scoping Review of Pharmacist-led Interventions in the Treatment of Latent Tuberculosis Infection

While the effectiveness of pharmacist interventions in the treatment of latent tuberculosis infection (LTBI) has been reported internationally, the role of pharmacists remains largely absent in Korea. This study aimed to examine the types and effects of pharmacist-led interventions during LTBI treatment and to derive implications for establishing the pharmacist’s role in the Korean context. A scoping review was conducted to identify and describe pharmacist-led interventions in LTBI care. Interventions have been implemented in diverse forms depending on the collaborative framework, including collaborative care models with primary care and community pharmacies, pharmacist-run clinics, or multidisciplinary team-based clinics. Throughout the LTBI treatment process, pharmacists, grounded in specialized clinical competencies, played multifaceted roles that contributed to improved treatment completion and patient safety. Their roles included patient education and counseling, adherence and adverse event management, ongoing support through follow-up and visit management, and collaboration with primary care providers or multidisciplinary teams. Our findings suggest the need to institutionalize the role of pharmacists in national LTBI management strategies in Korea and emphasize the importance of further research to build the evidence base for such initiatives.
