Implementation of Differentiated Service Delivery Model of Care for People Living with HIV with Comorbidities
This is an implementation study evaluating differentiated service delivery model for the care of comorbidities for people living with HIV (PLWH). The Hybrid Type 3 study design is adopted, with the primary goal of evaluating implementation outcomes, and secondary goals of evaluating service and client outcomes according to the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework, including Proctor's Conceptual Framework for Implementation Outcomes, using mixed methods for data collection and analyses. PLWH will be identified from the Integrated Treatment Centre, an HIV clinic in Hong Kong, which provides care to around 3500 PLWH, with services including out-patient care of patients with human immunodeficiency virus (HIV) infection, antiviral therapy for HIV and hepatitis co-infection, and treatment of sexually transmitted diseases. PLWH with comorbidities will be asked to participate in a survey for willingness to participate. Those interested will be co-managed at the HIV Comorbidities Clinic at the Prince of Wales Hospital, where the DSD model of care is conducted. Evaluation of implementation outcomes will be performed at the end of the programme.
• PLWH eligible to participate in this study are PLWH aged 18 years or above
• followed up at the HIV Clinic, and with one or more cardiometabolic comorbidities, including hypertension, diabetes, hyperlipidaemia, metabolic-associated fatty liver disease, cardiovascular diseases, and cerebrovascular diseases. They will be eligible if HIV physicians consider them having sub-optimal control of their comorbidities, suspected of having complications, or would benefit from screening of complications resulting from their comorbidities. These indications are selected as they involve specialist care, including investigations and treatment, which are not available at the HIV Clinic.
