Before project launch, key materials were prepared, including informed consents, posters, informational leaflets, patient cards, social media posts, standard operating procedures, patient management plans and patient registries. Necessary medical supplies (rapid tests for HIV, syphilis, hepatitis B and C, lancets, sterile pads, gloves and personal protective equipment) were secured.

The main field activity took place at the Health Care Centre for Ukrainian refugees in Bratislava (Rovniankova 1), operated by EQUITA and the Bratislava Administrative Region. The screening offer was promoted through posters, leaflets distributed to patients, and social media channels (Facebook, Instagram, Telegram). Testing was provided during regular operating hours to all patients.

A psychologist was available throughout the project to support patients with reactive results, help arrange appointments for laboratory confirmation and specialist care, and accompany patients if requested. Confirmatory diagnostics and treatment pathways were pre-arranged with University Hospital Bratislava (Dermatovenerology Clinic for syphilis; Infectious Diseases Clinic for HIV and viral hepatitis).

Rapid testing using capillary blood was conducted. Participants signed informed consent before testing. Four drops of finger-prick blood were applied to rapid test plates, with results available after 10 minutes. Patient IDs, anonymized codes and results were recorded. Regardless of results, all patients received basic counselling on the screened diseases and prevention. In reactive cases, patients were informed immediately, referred for confirmation, and provided psychological support. Confirmed patients received clinical evaluation and treatment covered by state health insurance. Medical and administrative supplies at the facility were replenished weekly.

A second field activity, "Health Day," was implemented at the Assistance Centre on Bottova Street, operated by the Municipality of Bratislava. Partners included the Regional Public Health Authority, the Bratislava Association of Medical Students and SCORA, and EQUITA. The event was promoted through posters and social media. Participants were offered rapid testing for HIV, syphilis, hepatitis B and C, as well as basic cardiovascular screening and stool tests for occult bleeding. Informational brochures, condoms, menstrual aids and patient cards were distributed.
