Healthcare in Nigeria's public hospitals often faces challenges related to patient satisfaction due to traditional gender biases in service delivery models. A mixed-methods approach involving surveys and qualitative interviews was employed to collect data from a representative sample of patients in various public hospitals across Nigeria. Analysis revealed that the introduction of gender-neutralized services led to an average increase of 15% in patient satisfaction scores, with notable improvements observed among both women and men who felt their specific needs were better addressed. The implementation of gender-neutral healthcare models significantly enhanced overall patient satisfaction in Nigerian public hospitals, particularly benefiting patients from traditionally marginalized groups. Public health authorities should continue to promote and implement gender-neutral healthcare practices to further improve service quality and patient outcomes.
