Comprehensive tuberculosis control for patients at high risk for noncompliance

Area of Science:

• Public Health
• Infectious Diseases
• Clinical Medicine

Background:

• High rates of noncompliance with tuberculosis treatment regimens are a significant challenge in the United States.
• Vulnerable populations, including those with HIV, homelessness, and substance use disorders, often face barriers to completing tuberculosis therapy.
• Effective tuberculosis control requires innovative strategies to ensure patient adherence and treatment success.

Purpose of the Study:

• To evaluate the effectiveness of a comprehensive, hospital-based tuberculosis control program.
• To assess the impact of directly observed therapy (DOT) and integrated support services on treatment compliance and outcomes.
• To determine the feasibility of achieving high cure rates in a high-risk patient population.

Main Methods:

• Development and implementation of a multidisciplinary program at Bellevue Hospital, including medical, nursing, and social services.
• Referral of patients to an on-site directly observed therapy (DOT) program with incentives and outreach for missed appointments.
• Retrospective analysis of treatment compliance and bacteriologic cure rates for 113 referred patients from November 1992 to July 1993.

Main Results:

• Of 113 referred patients, 102 completed therapy, achieving a 99% bacteriologic cure rate.
• Common comorbidities included HIV infection, homelessness, illicit drug use, and alcoholism.
• The program successfully managed patients through on-site DOT, community-based DOT, home medication, and self-medication, with only 11 patients lost to follow-up.

Conclusions:

• A comprehensive hospital-based tuberculosis control program, incorporating directly observed therapy (DOT) and robust support systems, is highly effective.
• This model demonstrates success in achieving high treatment adherence and cure rates, even among patients with significant social and medical challenges.
• Integrated care approaches are crucial for overcoming noncompliance barriers in tuberculosis management.
