Plain English summary of protocol

Background and study aims
Despite receiving adequate treatment, many tuberculosis (TB) survivors are left with post-tuberculosis complications, possibly due to lung tissue damage incurred during the active period of the disease. Current TB programs worldwide deliver quality care throughout the course of active TB treatment, yet often fail to provide organized follow-up once treatment ends. Post-tuberculosis lung disease (PTLD) is a prominent, yet underrecognized cause of chronic lung disease, managed similarly to chronic respiratory diseases with pharmacotherapy and/or personalized pulmonary rehabilitation interventions. Basic pulmonary rehabilitation packages for people finishing TB treatment are still lacking in low- and middle-income countries (LMICs). This study offers a protocol to evaluate the implementation of spirometry and symptom screening for PTLD among people who have completed TB treatment in a rural district in Mozambique.

Who can participate?
Patients aged ≥15 years of age enrolled in the NTCP at CHC with a GeneXpert-positive sputum

What does the study involve?
This study involves spirometry and symptom screening amongst those recently considered cured of TB to determine the prevalence of PTLD. All participants enrolled in the study will receive this intervention at baseline (upon enrollment) and at six-month follow-up. Using spirometry, Forced expiratory volume in one second (FEV1) and Forced Vital Capacity (FVC) will be measured in all participants.

What are the possible benefits and risks of participating?
This study will not likely benefit participants directly, but the knowledge gained from this study will be used to assist decision makers in determining a course of action for increasing spirometry screening coverage, optimizing the intervention’s impact, and translating our findings into evidence-based programming. There are no risks associated with participating in this study.

Scientific titleImplementation of spirometry screening for post-tuberculosis lung disease (PTLD) among adolescents and adults enrolled within the National Tuberculosis Control Program of Carmelo Hospital in Chókwè District, Mozambique: A hybrid type III effectiveness-implementation study protocol
Study objectivesAdaptations in the tuberculosis care and treatment care cascade that consider local, real-world inputs, will result in greater uptake in spirometry screening and subsequent treatment amongst persons recently completing tuberculosis treatment.

Health condition(s) or problem(s) studiedPulmonary lung function screening (spirometry) in persons completing 6 months of treatment for active TB
InterventionThis study involves pulmonary lung function screening (spirometry) in persons completing 6 months of treatment for active TB.

To document the prevalence of PTLD in patients enrolled at Carmelo Hospital (CHC), a prospective observational study will be conducted to introduce spirometry and symptom screening within the National TB Control Program (NTCP) at baseline (completion of six-months of TB treatment) and six months after completion of TB treatment. Patient enrollment into the spirometry screening program will continue for approximately three months following study initiation. Enrolled participants will complete standardized respiratory symptoms and quality of life questionnaires at each visit. Spirometry will be performed at each visit using spirometers that meet the International Organization for Standardization (IOS) standards.

For the qualitative portion of the study, a total of approximately 16-19 semi-structured key-informant interviews will be conducted that will include a minimum of two participants at the central level of the NTCP in Maputo (Mozambique’s capital city), two administrators of CHC, and one administrator at each of three selected peripheral health facilities. In addition, the study involves interviews with the three clinicians (1 physician, 1 medical technician, and 1 nurse) responsible for implementing the spirometry screening program at CHC, as well as all clinicians responsible for treating TB at each of the three selected peripheral health facilities (it is estimated there will be between two to three clinicians at each of the three health facilities).
Intervention typeProcedure/Surgery
Primary outcome measurePrevalence of post-tuberculosis lung disease amongst persons completing 6 months of treatment for active TB measured using spirometry and symptom screening at baseline (completion of 6 months of TB treatment) and at 6 months after completion of TB treatment.
Secondary outcome measuresSite-, provider-, and individual-level determinants that either promote or inhibit the successful adoption, implementation, and maintenance of the spirometry screening program will be measured using semi-structured key-informant interviews evaluating constructs from the Consolidated Framework for Implementation Research (CFIR), including perceptions about the intervention characteristics (e.g., facilitators, potential challenges, eligibility, and cost); outer setting factors influencing use (e.g., perception of patient needs and resources, demand creation, commitment); inner setting factors impacting uptake and fidelity to the intervention (e.g., resources needed, workload, standard operating procedures, infrastructure); characteristics of individuals (e.g., knowledge, competency, belief it can be done with quality); and process factors of implementation (e.g., fidelity, execution, and evaluation) within each health facility. These interviews will be performed after the completion of the spirometry portion of the study
