Abstract Background Child healthcare services such as diphtheria-tetanus-pertussis (DPT3) vaccination are known to reduce childhood mortality and morbidity. However, inequalities in access to these services in developing countries continue to constrain global efforts aimed at improving child health. This study examines the impact and equity effect of a community-based primary healthcare programme known as the Ghana Essential Health Intervention Programme (GEHIP) on improving the uptake of childhood DPT3 immunisation coverage in a remote rural region of Ghana. Methods Using baseline and end-line household survey data collected from mothers, the effect of GEHIP’s community-based healthcare programme on DPT3 immunisation coverage is evaluated using difference-in-differences multivariate logistic regression models. Household wealth index and maternal educational attainment were used as equity measures. Results At end-line, both intervention and comparison districts recorded increases in DPT3 immunisation coverage although intervention districts had a relatively higher coverage than comparison districts (90% versus 88%). While children resident in intervention areas had slightly higher rates than children resident in comparison areas, regression results show that this difference was not statistically significant (DiD = 0.038, p-value = 0.102). There were also no significant equity disparities in the coverage of DPT3 vaccination for both household wealth index and maternal educational attainment. Conclusion DPT3 vaccination coverage in both study arms met the global vaccine action plan targets. However, because estimated effects are not significantly higher among treatment area children than among comparison districts counterparts, no equity/inequity effects of the community-based healthcare programme on DPT 3 coverage is evident.
