Numerous nations are making concerted efforts to align with the demands of healthcare delivery, recognizing that the endurance and prosperity of a nation's economic and societal advancement hinge on the robustness of its healthcare sector. This is because poor healthcare can have a significant impact on the economic and social expectations of a nation's citizens. Hence, healthcare is an important unit in the Nigerian economy. This research aims to propose a link between the effect of service quality on patient satisfaction and loyalty in primary healthcare in Kano State. The formulation of the framework is based on a review of the literature on Service Quality. The paper presents a critical review of patient satisfaction, loyalty, and the Service model. For this paper, many books and articles from peer-reviewed papers published in international journals and conferences were reviewed throughout the research period. The proposed framework will assist policymakers in improving the dire condition of primary healthcare centers in Nigeria.
