Introduction
Conflicts between medical staff and service users in healthcare centers constitute a persistent social problem that imposes significant economic and moral costs on societies each year. A substantial part of these conflicts stems from perceived injustice and unfairness in healthcare service delivery. Social justice has become a central concern in citizens’ everyday experiences, and when individuals perceive that justice is undermined, they tend to question social norms, reduce social participation, and disengage from collective responsibilities. These dynamics are particularly critical in the health sector, where access to services is directly linked to life, well-being, and human dignity. In Mashhad, the limited number and spatial concentration of Social Security hospitals raise concerns regarding equitable spatial access and the broader context in which service users form perceptions of justice. Accordingly, this study addresses three main questions: (1) Are Social Security healthcare centers in Mashhad spatially distributed in an equitable manner? (2) How do service users perceive social justice when using these services? (3) Which factors are significantly associated with perceived justice?
Method
This study employed a descriptive–analytical design. In the spatial analysis phase, the distribution of Social Security hospitals and other medical facilities in Mashhad was examined to assess accessibility gaps using the P-Median model within a GIS framework. In the survey phase, data were collected from 300 service users visiting Social Security hospitals through a researcher-designed questionnaire. Content validity was confirmed by expert review, and reliability was verified using Cronbach’s alpha (0.83). Responses were measured on a five-point Likert scale. Data analysis was conducted using GIS tools and multivariate linear regression in SPSS.
Findings
The spatial analysis revealed that only two Social Security hospitals are currently active in Mashhad, forcing a considerable proportion of residents to incur high temporal and financial costs to access healthcare services. Survey results indicated that 38% of respondents reported low levels of perceived social justice, 48% reported moderate levels, and 14% reported high levels (table 1).

Regression analysis demonstrated that trust in staff competence, literacy level, perceived fairness, and sense of security significantly increased perceived justice, while feelings of alienation and residential neighborhood had a negative impact. Together, these variables explained 53% of the variance in perceived justice, highlighting the multidimensional nature of justice perceptions in healthcare settings (table 2).

Discussion
The findings indicate that although spatial accessibility constitutes an important contextual condition, service users’ perceptions of social justice are more strongly influenced by institutional and interactional factors. Consistent with the literature on procedural and distributive justice, trust in healthcare personnel, fairness in service provision, and a sense of security play a central role in shaping justice perceptions. Spatial inequality intensifies dissatisfaction by increasing access costs; however, it does not independently determine perceptions of justice. These results suggest that improving healthcare equity requires more than redistributing facilities across urban space. Enhancing service quality, strengthening institutional trust, and ensuring fair and respectful treatment of service users are crucial for reducing conflicts and improving patient satisfaction. Therefore, policy interventions should prioritize organizational reforms and patient-centered care alongside long-term spatial planning strategies.
