Experimentální: Primary Health Care Centers in the Federal Capital Territory
10 primary healthcare centers in Nigeria's Federal Capital Territory who previously demonstrated capacity to deliver hypertension care in HTN 1.0.
|
This study uses an interrupted time series design to compare diabetes screening, diagnosis, treatment, and control across a 12-month pre-implementation period and a 24-month implementation period in 10 primary healthcare centers in Nigeria's Federal Capital Territory.
Sites previously demonstrated capacity to deliver hypertension care and will continue hypertension services while expanding to diabetes care through the HEARTS diabetes module (HEARTS-D).
Pre-implementation includes registry setup and provision of glucometers without diabetes treatment training.
Implementation includes HEARTS-D training, supply provision, expansion of the drug revolving fund to diabetes medicines, and quarterly supportive supervision.
Description: Oral biguanide used as first-line glucose-lowering therapy within the HEARTS-D stepped-care protocol.
Dosing per protocol: 500 mg once daily (Step 1), 1000 mg once daily (Step 2), 1000 mg twice daily (Step 3 and Step 4).
Supplied through the expanded drug revolving fund during the implementation period.
Oral sulfonylurea used as add-on therapy at Step 4 of the HEARTS-D stepped-care protocol when blood glucose remains uncontrolled on metformin.
Starting dose 1 mg once daily, titrated by 1-2 mg to a maximum of 8 mg daily.
Supplied through the expanded drug revolving fund during the implementation period.
Point-of-care capillary blood glucose monitor with compatible single-use test strips and lancets, used at participating primary health centers for diabetes screening, diagnosis, and monitoring per WHO HEARTS-D.
Glucometers and test strips are provided to all sites during pre-implementation (registry setup) and replenished during implementation through the supply chain and drug revolving fund.
Ostatní jména:
Structured training of CHEWs on the HEARTS-D protocol covering diabetes screening, diagnosis, stepped-care treatment, follow-up, and referral, delivered at the start of the implementation period and reinforced by quarterly supportive supervision visits with audit-and-feedback throughout the 24-month implementation period.

Difference in 6-month rolling average diabetes screening in eligible adults (random plasma glucose with hyperglycemia symptoms; fasting plasma glucose if ≥18 y and BMI >25 kg/m²; or HbA1c) per WHO HEARTS-D, pre- vs. implementation
Časové okno: 36 months

Primary effectiveness outcome: The primary outcome will be the difference in the 6-month rolling average of the diabetes screening among eligible patients, screening defined as a random plasma glucose screening among adults with symptoms of hyperglycemia or a fasting plasma glucose among adults > 18 years old and body mass index > 25 kg/m2 in accordance with HEARTS-D, between the pre-implementation and implementation periods.
Hemoglobin A1c may also be used if available.
