Brief Summary:
This is a Hybrid design to primarily assess effectiveness, and to secondarily observe and collect data on the implementation of the service. This will allow the assessment of health-related outcomes and implementation outcomes to facilitate dissemination and replication if proven to be successful in other CBOs in Thailand, regionally, and globally.
Detailed Description:
Implementation Effectiveness To assess effectiveness, an interrupted time series (ITS) design. The counterfactual scenario (under which KP-led HCV test and treat had not been implemented) will be determined using routine service data collected from 15 months prior to the study implementation, and will provide a comparison for the evaluation of the impact of KP-led HCV test and treat by examining any change occurring in the primary outcomes in the post-implementation period during the 15 months of the study.
Implementation Strategies To assess implementation, Proctor's model was used to guide the selection of relevant implementation outcomes, which during this stage of implementation are acceptability, feasibility, and fidelity. Socio-ecological level, framework, and relevant constructs for each outcome are outlined below and in table 1.
1. Acceptability of KP-led HCV test and treat Acceptability refers to the perception that the service is agreeable and satisfactory. It will be measured using surveys at four socio-ecological levels, informed by different frameworks according to relevance
* Clients, pre-implementation: The Health Belief Model (HBM) will be used to design a survey to assess determinants that drive the acceptability of HCV test and treat services at the CBO. The HBM is one of the first theories of health behavior, and addresses the individual's perception of the threat posed by a health problem and factors influencing the decision to act. This assessment will be conducted pre-implementation, and findings will inform the design of implementation strategies targeting clients
* Clients, during implementation: To assess the acceptability and satisfaction of the same day HCV test and treat service, clients who initiated DAA treatment at the CBO will be asked to complete a standard survey on acceptability and satisfaction
* Providers: The Theory of Planned Behavior (TPB) will be used to design a survey to assess factors that influence the acceptability of HCV test and treat among KP-lay providers. The TPB examines the relations between an individual's belief, attitudes, intentions, behavior, and perceived control over that behavior. This assessment will be conducted pre-implementation, and findings will inform the design of implementation strategies targeting providers.
* CBO leadership: The Theory of Planned Behavior (TPB) will also be used to design a survey to assess factors that influence the acceptability of HCV test and treat among CBO leaderships. This assessment will be conducted pre-implementation, and findings will inform the design of implementation strategies targeting CBO leadership.
* Policy makers: The Consolidated Framework for Implementation Research (CFIR) will be used to produce interview guides to assess the acceptability of the service among key government stakeholders and policy makers.
2. Feasibility of providing KP-led HCV test and treat by KP-lay providers in CBOs
Feasibility refers to the extent to which the service can be successfully delivered within the CBO setting. It will be measured at two socio-ecological levels:
* Providers: Training records, and surveys and in-depth interviews informed by CFIR.
* CBO leadership: CFIR will be used to design surveys to assess relevant domains and constructs, and in-depth interviews will be conducted to further explore survey findings.
3. Fidelity of KP-led HCV test and treat implementation Fidelity refers to the extent to which the service was delivered as intended. It will be measured at the provider level using observation, checklists, and assessment of client records, guided by CFIR.
