Cohort study of the mortality among patients in New York City with tuberculosis and COVID-19, March 2020 to June 2022.

Both tuberculosis (TB) and COVID-19 can affect the respiratory system, and early findings suggest co-occurrence of these infectious diseases can result in elevated mortality. A retrospective cohort of patients who were diagnosed with TB and COVID-19 concurrently (within 120 days) between March 2020 and June 2022 in New York City (NYC) was identified. This cohort was compared with a cohort of patients diagnosed with TB-alone during the same period in terms of demographic information, clinical characteristics, and mortality.

In-Person vs Electronic Directly Observed Therapy for Tuberculosis Treatment Adherence: A Randomized Noninferiority Trial.

Importance: Electronic directly observed therapy (DOT) is used increasingly as an alternative to in-person DOT for monitoring tuberculosis treatment. Evidence supporting its efficacy is limited.

Objective: To determine whether electronic DOT can attain a level of treatment observation as favorable as in-person DOT.

Cost of Tuberculosis Therapy Directly Observed on Video for Health Departments and Patients in New York City; San Francisco, California; and Rhode Island (2017-2018).

To assess costs of video and traditional in-person directly observed therapy (DOT) for tuberculosis (TB) treatment to health departments and patients in New York City, Rhode Island, and San Francisco, California. We collected health department costs for video DOT (VDOT; live and recorded), and in-person DOT (field- and clinic-based). Time-motion surveys estimated provider time and cost.

Using Video Technology to Increase Treatment Completion for Patients With Latent Tuberculosis Infection on 3-Month Isoniazid and Rifapentine: An Implementation Study.

Background: Since January 2013, the New York City (NYC) Health Department Tuberculosis (TB) Program has offered persons diagnosed with latent TB infection (LTBI) the 3-month, once-weekly isoniazid and rifapentine (3HP) treatment regimen. Patients on this treatment are monitored in-person under directly observed therapy (DOT). To address patient and provider barriers to in-person DOT, we piloted the use of a videoconferencing software app to remotely conduct synchronous DOT (video directly observed therapy; VDOT) for patients on 3HP.

A National Survey on the Use of Electronic Directly Observed Therapy for Treatment of Tuberculosis.

Context: An increasing number of tuberculosis (TB) programs are adopting electronic directly observed therapy (eDOT), the use of technology to supervise patient adherence remotely. Pilot studies show that treatment adherence and completion were similar with eDOT compared with the standard in-person DOT.

Objective: In December 2015, the National Tuberculosis Controllers Association administered an online survey to determine the extent to which eDOT is used in the United States.

Treatment for Tuberculosis Infection With 3 Months of Isoniazid and Rifapentine in New York City Health Department Clinics.

Background: Completion of treatment for tuberculosis infection (TBI) with 9 months of self-administered daily isoniazid (9H) has historically been low (<50%) among New York City (NYC) Health Department tuberculosis clinic patients. Treatment of TBI with 3 months of once-weekly isoniazid and rifapentine (3HP) administered under directly observed therapy (DOT) might increase treatment acceptance and completion.

Methods: The study population included patients diagnosed with TBI at 2 NYC Health Department tuberculosis clinics from January 2013 through November 2013.

Treatment Outcomes of Patients with Tuberculosis in New York City.

Context: Treatment completion for tuberculosis (TB) is one of the essential components of TB prevention and control. Delays in treatment completion and incomplete treatment can result in increased transmission, development of drug resistance, and increased morbidity and mortality. Understanding the reasons for poor treatment outcomes may help improve TB control efforts.

Strain-specific differences in two large Mycobacterium tuberculosis genotype clusters in isolates collected from homeless patients in New York City from 2001 to 2004.

We studied two large Mycobacterium tuberculosis genotype clusters associated with recent outbreaks in homeless persons to determine factors associated with these tuberculosis (TB) strains. Isolates from all culture-positive TB cases diagnosed from 1 January 2001 to 31 December 2004 were genotyped. Patients whose isolates had identical restriction fragment length polymorphism patterns and spoligotypes were considered clustered.

Which patients' factors predict the rate of growth of Mycobacterium tuberculosis clusters in an urban community?

Factors influencing tuberculosis cluster growth are poorly understood. The authors examined clusters of two or more culture-confirmed Mycobacterium tuberculosis cases between January 1, 2001, and December 31, 2003, that had insertion sequence 6110 (IS6110) restriction fragment length polymorphism and spoligotype patterns identical to those of another study case. Genotypes first seen in New York, New York, before or during 1993 were considered historical; recent strains were those first seen after 1993.

Health department costs of managing persons with suspected and noncounted tuberculosis in New York City, Three Texas counties, and Massachusetts.

Objectives: To describe persons with suspected (did not meet the national tuberculosis [TB] surveillance case definition) and noncounted TB (met the TB case definition but transferred and were counted by another jurisdiction) and estimate costs incurred by public health departments for managing them.

Methods: We reviewed TB registry, medical records, budgets, bills, salaries, organizational charts, and travel/activity logs from the year 2000 at health departments in New York City (NYC), three Texas (TX) counties (El Paso, Hidalgo, and Webb), and Massachusetts (MA). We also interviewed or observed personnel to estimate the time spent on activities for these patients.
