Task-shifted Adaptation of the WHO-PEN Intervention to Address Cardio-metabolic Complications in People Living With HIV in Zambia

Objective 1

Focus group discussion participants/implementation survey participants:

Inclusion:

• 18 years of age or older
• non-physician professional or lay/peer health care worker (HCW) involved with HIV and/or NCD service delivery.

Key Informant Interview (KII) participants:

• 18 years of age or older
• a senior Ministry of Health (MOH) policy maker or health official working at national level in Zambia involved in managing, coordinating, and/or overseeing health services for non-communicable diseases in Zambia.

In-depth interview participants:

• emancipated HIV-infected adults 18 years of age or older have a documented cardio-metabolic condition

Exclusion:

• any potential IDI, FGD, or KII participant if they are unwilling or unable to provide informed consent.

Objective 2:

Cross-sectional assessments:

Inclusion:

• HIV-infected
• aged 18 years and older
• seeking care at either of the two ACHIEVE-supported pilot sites who are screened for and/or found to have evidence of one or more of the cardio-metabolic conditions or risk factors.

Nested cohort participants:

Inclusion:

• documented HIV infection
• aged 18 years or older
• have one or more cardio-metabolic conditions or risk factors:
• obesity (defined as BMI > 30 kg/m^2);
• any current tobacco smoking;
• hypertension as defined by WHO PEN (i.e., systolic blood pressure (SBP) = 140 mmHg and/or diastolic blood pressure (DBP) = 90 mmHg);
• diabetes mellitus as defined by WHO PEN (i.e. random plasma glucose = 11.1 mmol/L, fasting plasma glucose = 7 mmol/L, and/or haemoglobin A1c = 48 mmol/mol);
• prediabetes (defined as having impaired fasting glucose of 6.1 to 6.9 mmol/L, impaired glucose tolerance with a two-hour, post-oral glucose tolerance test glucose =7.8 mmol/L but 4 mmol/L or low density lipoprotein =6 mmol/L); and/or 7) personal history or medication use for heart disease, heart failure, stroke, or other cardio-metabolic complication (including but not limited to coronary artery disease, cerebrovascular disease, myocardial infarction, stroke, or peripheral vascular disease).

IDI participants:

• HIV-infected
• 18 years of age who were enrolled in the nested cohort and had documented exposure to the TASKPEN intervention at a pilot site.

FGD participants:

• 18 years of age or older
• a non physician health care worker (NPHW) or community health worker (CHW)/ lay health provider involved with TASKPEN or integrated HIV/NCD service delivery generally familiar with HIV and/or NCD service delivery at their facility.

KII participants:

• 18 years of age or older
• a facility-level antiretroviral therapy (ART) or out-patient department (OPD) clinic manager/ in-charge or policy maker at district, provincial, or national level in Zambia; and generally familiar with HIV and/or NCD-related issues in their community.

Exclusion criteria

For the nested cohort component, investigators will exclude:

• adults who have no documented evidence of having established HIV care at the sites.
• people unlikely to remain at the site to the completion of the study follow-up.
• any potential IDI, FGD, or KII participant if they are unwilling or unable to provide written informed consent.
