Since its establishment, the NHIS has been providing financial access to healthcare services for members of the scheme and contributing to the financial resource of healthcare providers. Nonetheless, the overwhelming initial popularity of the NHIS has not translated into high enrolment and regular renewal of membership in recent years. Enrolment peaked during the early years of implementation and stagnated around 40% of the population between 2011 and 2015.11 Although every health insurance system, much so a practically voluntary system such as the NHIS, is subject to the natural attrition of its members, high drop-out rates are a huge concern especially for realising the overarching goal of UHC. In respect of the above-mentioned challenge, a community outreach registration intervention was piloted in the Kadjebi, Ketu North, and North Tongu districts of the Volta region, from October 2016 to December 2018 in two phases, in collaboration with the Korea Foundation for International Healthcare (KOFIH). Prior to the intervention study, a baseline study was conducted in 2015 in the region, which revealed that distance to the NHIS district office and lack of knowledge of the scheme were major barriers to enrolment.11 These findings informed the design of the community outreach intervention, which comprised expansion of unit- based registration centres and information, education and communication (IEC) to address the identified enrolment challenges and boost enrolment in the NHIS. Phase one of the intervention occurred from October 2016 to July 2017 and the findings showed significant improvement in enrolment in the Kadjebi district, where the expansion of the unit base registration centres took place. The IEC had little effect on enrolment in the Ketu North district, which was one of the intervention districts. In view of these findings, the pilot project was scaled up (phase II) only in the Kadjebi district from April to December 2018 with the hope to achieve more significant improvements in enrolment. In this paper, we investigated the effect of the intervention on NHIS enrolment and knowledge. We https://e-jghs.org https://doi.org/10.35500/jghs.2020.2.e8 2/12 Health insurance enrolment, knowledge and health services utilisation hypothesized that bringing the registration closer to the communities would increase enrolment in the NHIS and participants' knowledge of the scheme. We also investigated the effect of the intervention on utilisation of healthcare services 12 months prior to the follow-up survey. A few intervention studies have been conducted in Ghana12,13 and other LMICs.14-16 These studies employed similar interventions (subsidies, on-site enrolment/convenience sign-up, and education/information) and found short-term (12 months) positive and significant effects on health insurance enrolment. However, there are conflicting effects of the interventions on participants' knowledge of health insurance and utilisation of healthcare services. Whilst some of the studies found positive
