Adapting a mobile TB screening unit to provide integrated screening services and linkage to primary care.

Objective: We adapted a mobile TB screening unit to create an integrated screening program for noncommunicable diseases and TB, using community health worker (CHW) navigators to support linkage to care. We piloted the model in underserved communities of Lima, Peru, evaluating its feasibility, acceptability, and ability to continue supporting TB case detection.

Design: The program provided screening for TB, hypertension, diabetes, and depression and was rebranded to avoid TB-associated stigma.

Barriers and facilitators to tuberculosis diagnosis in Lima, Peru: a mixed methods study.

Background: Tuberculosis (TB) infectiousness decreases significantly with only a few days of treatment, but delayed diagnosis often leads to late treatment initiation. We conducted a sequential explanatory mixed methods study to understand the barriers and facilitators to prompt diagnosis among people with TB.

Methods: We enrolled 100 adults who started TB treatment in the Carabayllo district of Lima, Peru, between November 2020 and February 2022 and administered a survey about their symptoms and healthcare encounters.

Exploring the role of the private sector in tuberculosis detection and management in Lima, Peru: a mixed-methods patient pathway analysis.

In Latin America, little is known about the involvement of private healthcare providers in TB detection and management. We sought to gain a better understanding of current and potential roles of the private sector in delivering TB services in Peru. We conducted a mixed-methods study in Lima, Peru.

Person-centered strategies for delivering TB diagnostic services in Lima, Peru.

Setting: Lima, Peru.

Objective: To close the gap in TB diagnosis, TB diagnostic services must match care-seeking preferences. We sought to identify preferred strategies for delivering TB diagnostic services and to determine whether preferences differ among demographic groups.

The impact of the COVID-19 pandemic on patients' experiences obtaining a tuberculosis diagnosis in Peru: a mixed-methods study.

Background: The COVID-19 pandemic disrupted TB services worldwide, leading to diagnostic delays. There have been few published reports describing how the pandemic affected people's pathway to diagnosis from their own perspectives. We sought to evaluate the impact on the pandemic on people's experiences obtaining a TB diagnosis.

Geospatial analysis of reported activity locations to identify sites for tuberculosis screening.

Mobile screening units can help close tuberculosis case detection gaps. Placing screening units where people at high risk for undiagnosed tuberculosis preferentially spend time could make screening more resource-effective. We conducted a case-control study in Lima, Peru to identify locations where people with tuberculosis were more likely to spend time than community controls.
