作者： Nnenna Mba-Oduwusi Ifesinachi Eze Tochukwu Osuji Maxwell Obubu Tolulope Oyekanmi Oluwatosin Kolade Ozioma Oguguah jane Martins Nkata chuku Alozie Ananaba Rodio Diallo Firdausi Umar Sadiq Emmanuella Zamba Abiola Idowu InSiGHt Health consulting Limited Ikeja Nigeria Health Systems consult Limited Abuja Nigeria Bill & Melinda Gates Foundation Abuja Nigeria Lagos State Health Management Agency (LASHMA) Lagos Nigeria Health Facility Monitoring and Accreditation Agency (HEFAMAA) Ikeja Nigeria

Background: Nigeria, a nation grappling with rapid population growth, economic intricacies, and complex healthcare challenges, particularly in Lagos State, the economic hub and most populous state, faces the challenge of ensuring quality healthcare access. The overview of the effect of quality improvement initiatives in this paper focuses on private healthcare providers in Lagos State, Nigeria. The study assesses the impact of donor-funded quality improvement projects on these private healthcare facilities. It explores the level of participation, perceived support, and tangible effects of the initiatives on healthcare delivery within private healthcare facilities. It also examines how these initiatives influence patient inflow and facility ratings, and bring about additional benefits and improvements, provides insights into the challenges faced by private healthcare providers in implementing quality improvement projects and elicits recommendations for improving the effectiveness of such initiatives. Methods: Qualitative research design was employed for in-depth exploration, utilizing semi-structured interviews. Private healthcare providers in Lagos involved in the SP4FP Quality Improvement Project were purposively sampled for diversity. Face-to-face interviews elicited insights into participation, perceived support, and project effects. Questions covered participation levels, support perception, changes observed, challenges faced, and recommendations. Thematic analysis identified recurring themes from interview transcripts. Adherence to ethical guidelines ensured participant confidentiality and informed consent. Results: Respondents affirmed active involvement in the SP4FP Quality Improvement Project, echoing literature emphasizing private-sector collaboration with the public sector. While acknowledging positive influences on facility ratings, respondents highlighted challenges within the broader Nigerian healthcare landscape affecting patient numbers. Respondents c
