Purpose: Non-communicable diseases (NCDs), especially hypertension, diabetes mellitus and cancers, are a growing public health concern in Kenya, contributing significantly to morbidity and premature mortality. In response, Kenya has strengthened community-based health strategies, with Community Health Volunteers (CHVs) now known as Community Health Promoters (CHPs) playing a key role in early detection, health promotion, and linkage to care. The study aims to explore determinants and outcomes of NCD screening and linkage to care among CHVs in Nyeri County.
Methodology: A quasi-experimental study was conducted that utilized a mixed-method approach among CHVs in intervention and control groups across 10 community units in Nyeri County. Data on CHV sociodemographic characteristics, training, supervision, incentives, availability of screening tools, and community engagement were collected. NCDs outcomes included screening coverage, identification of hypertension and diabetes, and linkage to care. Logistic regression was used to identify determinants of CHV effectiveness.
Findings: Enhanced training, regular supervision, and access to screening tools were significantly associated with higher screening rates (AOR = 2.8, 95% CI: 1.9–4.1). CHVs in the intervention group screened 78% of eligible community members, compared with 52% in the control group (p < 0.001). Linkage to care was significantly higher in the intervention group (65% vs. 38%; p<0.01), and was positively influenced by follow-up mechanisms and community awareness. Notably, CHV experience (>2 years) and the presence of supportive community structures also predicted better performance.
Unique Contribution to Theory, Practice and Policy: Enhanced CHV programs significantly improve NCD screening and linkage outcomes. Strengthening CHV training, supervision, resource provision, and community engagement is vital for sustainable NCD control in Kenya and similar low-resource settings.
