The WARM Study is a Pilot Study That Aims to Investigate the Impact of Environmental Factors on Acute and Chronic Wounds, Mental Illness, and Social Factors Among People Experiencing Housing Emergencies in Augsburg.

Providing healthcare to homeless people is a key and challenging task, both for society as a whole and for medical and psychosocial professionals. It must be noted that the standard healthcare system is hardly used, or can only be used to an insufficient extent, by homeless people, and therefore does not comprehensively reach this group. One low-threshold and acceptance-oriented service outside the standard care system is the Johanniter-Hilfsmobil, which was established on June 3, 2024, as an innovative approach to healthcare for homeless people in Augsburg and will be scientifically examined in the following study. The aim is to compare acute and chronic wounds in people experiencing housing emergencies who are treated by the Johanniter-Hilfsmobil with those of patients who attend the outpatient wound clinic at the Clinic for Vascular Surgery at Augsburg University Hospital. In addition, a saliva test will be carried out to estimate the amount and type of substance consumed, and a survey will be conducted among drug-dependent test subjects who present themselves either via the Johanniter-Hilfsmobil or via the substitution outpatient clinic of the Clinic for Psychiatry, Psychotherapy, and Psychosomatics at Augsburg District Hospital. Another focus of research is the quantitative and qualitative analysis of the psychosocial living situation and environmental influences on users of the Johanniter-Hilfsmobil.
