The paper considers a problem at the intersection of sociology, anthropology, law and multidisciplinary public health research - health care accessibility during a sudden social crisis. The authors test the theoretical assumptions on the example of the covid-19 pandemic in Serbia, trying to understand the specific position of non-covid patients suffering from chronic non-communicable diseases and their perceptions regarding health care accessibility during the period of the pandemic. The empirical data on which the analysis was performed was collected with the help of focus group interviews. The sample consisted of interviewees - representatives of the association of patients suffering from chronic non-communicable diseases that burden the population of Serbia the most, who live on the territory of the Republic of Serbia without Kosovo and Metohija. The analysis shows that access to health care during the pandemic was limited and that the protocols that the state and the health care system were setting up in the process did not take into account the specific needs of this socially vulnerable group of patients. This, due to the impossibility for them to go through certain diagnostic procedures in time, receive adequate therapy and/or rehabilitation, in a large number of cases resulted in the deterioration of the clinical picture of the chronic disease from which they suffer. The paper presents theoretical and practical conclusions, which aim to show how important it is to incorporate theoretical and empirical insights from the social sciences and humanities in the conceptualization and future implementation of public health protocols for future social crises in order to reduce their potential syndemic effect.
