“…Another study, conducted in Melbourne, Australia, incorporated the travel time from priority areas to palliative medicine and hospital services as estimates of accessibility thereby identifying the most vulnerable areas with respect to COVID-19 to be those where people were generally ≥ 65 years old and/or where people lived with disabilities [ 34 ]. While a study in Colombia found a high degree of spatial heterogeneity for ICU supplies in the study area by employing the E2SFCA to evaluate available ICU supplies for every thousand inhabitants in the Manizales-Villa María metropolitan area during the COVID-19 pandemic [ 35 ], results based on the same technique in Chicago, USA suggest that southern Chicago needs additional health care resources and that vulnerable populations often resided in areas with too low spatial accessibility [ 36 ].…”

Background There are only limited studies on access to COVID-19 vaccines and identifying the most appropriate health centres for performing vaccination in metropolitan areas. This study aimed to measure potential spatial access to COVID-19 vaccination centres in Mashhad, the second-most populous city in Iran. Methods The 2021 age structure of the urban census tracts was integrated into the enhanced two-step floating catchment area model to improve accuracy. The model was developed based on three different access scenarios: only public hospitals, only public healthcare centres and both (either hospitals or healthcare centres) as potential vaccination facilities. The weighted decision-matrix and analytic hierarchy process, based on four criteria (i.e. service area, accessibility index, capacity of vaccination centres and distance to main roads), were used to choose potential vaccination centres looking for the highest suitability for residents. Global Moran’s index (GMI) was used to measure the spatial autocorrelation of the accessibility index in different scenarios and the proposed model. Results There were 26 public hospitals and 271 public healthcare centres in the study area. Although the exclusive use of public healthcare centres for vaccination can provide the highest accessibility in the eastern and north-eastern parts of the study area, our findings indicate that including both public hospitals and public healthcare centres provide high accessibility to vaccination in central urban part. Therefore, a combination of public hospitals and public healthcare centres is recommended for efficient vaccination coverage. The value of GMI for the proposed model (accessibility to selected vaccination centres) was calculated as 0.53 (Z = 162.42, P < 0.01). Both GMI and Z-score values decreased in the proposed model, suggesting an enhancement in accessibility to COVID-19 vaccination services. Conclusions The periphery and poor areas of the city had the least access to COVID-19 vaccination centres. Measuring spatial access to COVID-19 vaccination centres can provide valuable insights for urban public health decision-makers. Our model, coupled with geographical information systems, provides more efficient vaccination coverage by identifying the most suitable healthcare centres, which is of special importance when only few centres are available.

Background: Limited studies have been conducted on access to COVID-19 vaccines and identifying the most appropriate health centres for performing vaccination in metropolitan areas. This study aimed to measure potential spatial access to COVID-19 vaccination centres in Mashhad, the second-most populous city in Iran.Methods: The age structure of the urban census tracts was integrated into the enhanced two-step floating catchment area model to improve accuracy. The model was developed based on three different scenarios: only public hospitals, only public healthcare centres, and the top 20% healthcare centres were employed as potential vaccination facilities. The weighted decision-matrix and analytic hierarchy process based on four criteria (i.e. service area, accessibility index, capacity of vaccination centres, and distance to main roads) were used to choose potential vaccination centres with the highest suitability for residents.Results: Our findings indicate that including the both public hospitals and public healthcare centres can provide high accessibility to vaccination in central parts of the urban areas. However, using only public healthcare centres for vaccination can provide higher accessibility to vaccination sites in the eastern and north-eastern parts of the study area. Therefore, a combination of public hospitals and public healthcare centres is recommended for efficient vaccination coverage.Conclusions: Measuring spatial access to COVID-19 vaccination centres can provide valuable insights for urban public health decision-makers. Our model, coupled with geographical information systems (GIS), provides more efficient vaccination coverage by identifying the most suitable healthcare centres, which is of special importance when only few centres are available.

“…Additionally, the spread has accelerated to the point where it has reached a large number of countries throughout the world. Given the great level of influence, it may have on developing countries, where health and hospital capability is smaller than that of developed countries, COVID-19 has been declared as a pandemic ( Escobar et al, 2020 ).…”

“…A study by Escobar et al (2020) used the E2SFCA model to evaluate the existing ICU supply per thousand people in the Manizales-Villamaría Metropolitan Area, considering the current hospital capacity and the average travel time to the hospital network. The results obtained by the E2SFCA method were compared with those obtained by analysis of minimum roads and their correlation with the economic conditions of the studied areas and allowed identifying the areas that would be neglected regarding different scenarios, which is a necessary stage in developing a successful prevention programs.…”
