Healthcare infrastructure and the provision of the healthcare system are the basic amenities for sustainable development that can improve health and wealth. Also, the healthcare system can improve with good infrastructure and providers for delivering healthcare intervention as per WHO guidelines. This chapter minutely executes the magnitude of the provision of different healthcare infrastructure and healthcare services, determines the most vulnerable slum neighborhoods and their perception of existing facilities, exhumes how far these facilities increase risk, and thoroughly evaluates the effectiveness of existing measures to inhibit problems of facilities that victimize the urban poor households. Finally, some situational environmental prevention measures have been provided to help taking necessary initiatives to curb this social issue. This chapter also focuses on the deficient areas of healthcare centers and thereby finds suitable areas for new healthcare centers incorporating all the physical and social aspects and the needs of the urban poor through the application of AHP, OLS, and geospatial analysis regarding the healthcare system hierarchy that can remove health disparities and reduces health-related problems.
