**Author and Year** & **Purpose of Research** & **Key Findings** \\ \hline [PERSON], [PERSON], [PERSON], 2019 [29] & The article presents an open-source tabular tool as support in decisions on facility locations. & Using the tool in a healthcare case study, computer tests showed that comparable values can be optimally solved in decision making on the location of facilities. \\ \hline [PERSON] et al., 2019 [30] & The main objectives of the research are to devise a healthcare system, increase the level of coverage, and reduce operating costs. The study proposes a new multiple target mathematical model to form compact, balanced and adjacent districts in healthcare systems. The target functions reduce heterogeneous distortion and monitoring costs for hygiene and public healthcare. \\ \hline [PERSON] et al., 2019 [31] & This study provides useful information on the planning and design of urban green areas with specific characteristics that could improve their accessibility and aesthetic quality, particularly from the aspect of older adults. & The results show that the duration of visits to green areas positively affects the mental and social health of people. The statistical model showed that such a connection is particularly important to women and people with low social support and social capital. \\ \hline [PERSON] et al., 2020 [32] & The research focuses on disparities in the inequality of healthcare for older adults in spatial and temporal terms. & The findings may assist policymakers in the planning of healthcare services for the increasingly older population and with the provision of information on carers for prompt and efficient treatment. \\ \hline [PERSON] et al., 2020 [33] & The objective of this study is to examine the spatial access to primary, secondary and tertiary healthcare services for older adults with an explicit focus on fairness and equal distribution of geographic accessibility. \\ \hline [PERSON], [PERSON], [PERSON], 2020 [34] & The objective of this study is to examine the spatial access to primary, secondary and tertiary healthcare services for older adults with an explicit focus on fairness and equal distribution of geographic accessibility. \\ \hline [PERSON], 2020 [34] & The objective of this study is to examine the spatial access to primary, secondary and tertiary healthcare services for older adults. The analysis distribution of geographic accessibility. \\ \hline [PERSON], [PERSON], [PERSON], 2020 [34] & The goal of the review article was to select qualitative evidence to understand the participants’ reasons for their decisions on the locations of care for older adults. The analysis included 46 articles. & The main outcome is the differentiation of several reasons for each group of people participating in the decision-making process on the locations of care. The reasons are divided into three factors: retention, pull or push. Such a differentiation facilitates a more detailed and in-depth analysis of the motivation of various groups participating in this process. \\ \hline [PERSON], [PERSON], 2020 [35] & The purpose of the article is to study the questions of healthcare planning and focus on the potential of the GIS models in solving these questions by using analytical approaches, i.e., to use analytical approaches to solve the problem of healthcare planning using the GIS models. \\ \hline \hline \end{tabular} The results show that 91.1 per cent of the global population can reach a hospital/clinic if they have access to a motorised vehicle, but only 56.7 per cent can go on foot. Maps point out the additional vulnerability of individuals in low-income areas, where long travel times are related to higher transport costs.
