Abstract (English)
Spatial accessibility is a crucial element in urban planning, as it ensures the optimal distribution of services. A method known as the Floating Catchment Area (FCA) uses provider-population ratios and cost to quantify access. In this study, four variations of FCA were employed in Metropolitan Iloilo-Guimaras to address the healthcare situation of the region. The procedure involved the acquisition of a network cost (i.e., travel time) and the definition of supply-demand zones, which generated a spatial accessibility index (SPAI). Using the Spearman Rank Correlation test, the mortality rates of each zone in the region were compared with their corresponding scores, which indicated the ideal model for the study area. By the end of the statistical analysis, the Enhanced Two-Step Floating Catchment Area Method (E2SFCA) showed a stronger relationship with the dependent variable. This was then used to optimize the healthcare system of the region. Three approaches were then explored, namely by capacity increase through renovation, integration of ambulance outposts, and construction of new healthcare facilities (HCFs). Using the initial zone-to-zone travel times obtained from the traffic simulation software, EMME, a preliminary basis for suggesting facilities was established. Experimenting with the capacity increase revealed zones that retain their poorly serviced status due to travel time, which is aggravated by distance decay. On the other hand, the integration of ambulance outposts demonstrated the impact of added coverage, while the construction of new HCFs proved to be the most effective, though it should be evaluated first by integrating ambulance outposts. After the optimization process, achieving the local standard of 1 hospital bed per 1,000 people required the construction of 1 primary HCF, 2 secondary HCFs, 1 tertiary HCF, and 5 ambulance outposts, while distributing 250 beds among existing HCFs. Meanwhile, reaching the international standard of 3:1000 needed an additional tertiary HCF, 2 ambulance outposts, and the distribution of 2,916 additional beds. Effectively, the FCA demonstrated its ability to propose alternatives to optimize a service network within an area.

Abstract (Filipino)
Ang spatial accessibility ay mahalagang elemento sa urban planning sapagkat tinitiyak nito ang pinakamainam na distribusyon ng mga serbisyo. Ang isang metodong kilala bilang Floating Catchment Area (FCA) ay gumagamit ng provider-population ratios (PPR) at cost upang masukat ang antas ng accessibility. Sa pag-aaral na ito, apat na baryasyon ng FCA ang ginamit sa Metropolitan Iloilo-Guimaras upang matugunan ang mga hamon sa sitwasyong pangkalusugan sa rehiyon. Kabilang sa proseso ang pagkuha ng network cost (hal., haba ng biyahe) at ang pagtukoy ng mga supply-demand zone, na nagbubunga ng spatial accessibility index (SPAI). Sa pamamagitan ng Spearman Rank Correlation test, inihambing ang mortality rates ng bawat sona sa rehiyon sa kanilang kaukulang mga iskor upang matukoy ang pinakamainam na modelo para sa lugar ng pag-aaral. Matapos ang estadistikal na pagsusuri, ipinakita ng Enhanced Two-Step Floating Catchment Area Method (E2SFCA) ang mas matibay na ugnayan sa dependent variable. Dahil dito, ito ang ginamit upang maging optimal ang sistema ng pangangalagang pangkalusugan sa rehiyon. Tatlong pamamaraan ang sinuri. Ito ay ang pagtaas ng kapasidad sa pamamagitan ng renovasyon, ang integrasyon ng mga ambulance outpost, at ang pagtatayo ng mga bagong healthcare facilities (HCFs). Gamit ang zone-to-zone travel times na nakuha mula sa traffic simulation software na EMME, nakabuo ng paunang batayan para sa pagrekomenda ng mga pasilidad. Ipinakita ng pagsusuri sa pagtaas ng kapasidad na may mga sonang nananatiling kulang sa serbisyo dahil sa travel time, na lalo pang pinalalala ng distance decay. Sa kabilang banda, ipinamalas ng integrasyon ng mga ambulance outpost ang epekto ng karagdagang sakop, samantalang napatunayang pinakamabisa ang pagtatayo ng mga bagong HCFs, bagaman nararapat muna itong suriin kasabay ng integrasyon ng mga ambulance outpost. Matapos ang proseso ng optimisasyon, ang pagkamit ng lokal na pamantayan na 1 hospital bed bawat 1,000 na tao ay nangangailangan ng pagtatayo ng isang pangunahing HCF, dalawang sekundaryang HCFs, isang tersiyaryong HCF, at limang ambulance outposts, kasama ang pamamahagi ng 250 kama sa mga umiiral na HCFs. Samantala, ang pag-abot sa internasyonal na pamantayan na 3:1000 ay nangangailangan ng karagdagang 1 tersiyaryong HCF, 2 ambulance outposts, at pamamahagi ng 2,916 karagdagang kama. Sa kabuuan, ipinakita ng FCA ang kakayahan nitong magmungkahi ng mga alternatibo upang maging optimal ang network sa loob ng isang lugar.
