Evaluation of a pharmacist-led multidisciplinary approach to the treatment of latent tuberculosis in refugee patients in the primary care setting.

BACKGROUND

Treatment of latent tuberculosis infection (LTBI) is essential for refugee patients who have been relocated to the United States to prevent progression to active infection.

OBJECTIVE

This study aimed to determine the effectiveness of a multidisciplinary team approach, embedded within a primary care clinic, to treatment of LTBI in newly resettled refugee patients compared with a local health department.

METHODS

This was a single-center, retrospective chart review of newly resettled refugee patients 18-89 years old with a diagnosis of LTBI. The primary objective was completion rate of LTBI therapy within 1 year of resettlement. Secondary objectives were incidence of adverse events, regimen switches, and adherence rate.

RESULTS

A total of 58 patients were included in the study: 14 individuals through the multidisciplinary clinic and 44 individuals with the local health department. Completion of therapy within 1 year of resettlement was seen in 71.4% of patients (n = 10) in the multidisciplinary clinic compared with 72.7% (n = 32) at the health department. There were 7 patients who underwent a regimen switch, all of whom were in the health department arm. Adverse effects occurred in 14.2% of patients in the multidisciplinary clinic and 15.9% of patients in the health department arm. Treatment adherence was 98.6% in the multidisciplinary clinic and 90.5% in the local health department arm.

CONCLUSION

Use of a multidisciplinary team was successful in completion of LTBI treatment in refugee patients, helping to alleviate barriers to treatment completion by ensuring adherence and close follow-up.
