This prospective observational before-after study evaluates the impact of a Mobile Geriatric Unit (MGU) on hospitalisation rates among nursing home residents. The study includes a 12-month control phase with usual care followed by a 12-month intervention phase during which the MGU is implemented. The MGU provides advanced on-site diagnostics and telemedicine-supported specialist consultation within nursing homes.
This prospective observational before-after study evaluates the impact of a Mobile Geriatric Unit (MGU) on hospitalisation rates among nursing home residents in Saarland, Germany. The study includes a 12-month control phase with usual care followed by a 12-month intervention phase with MGU implementation in 46 nursing homes. The MGU provides on-site advanced diagnostics (CT, X-ray, ultrasound, ECG, EEG, and laboratory testing) supported by telemedicine consultation with hospital specialists. A physician and radiology technician perform diagnostics in the nursing home, with results communicated to the general practitioner for treatment decisions within 48 hours. Usual care involves hospital referral and in-hospital diagnostics. The intervention aims to reduce avoidable hospital admissions by providing diagnostics and specialist input directly in the nursing home. The primary outcome is hospital admissions per person-year. Secondary outcomes include mortality, functional and cognitive status, quality of life (EQ-5D-5L), complications, healthcare costs, and 30-day hospitalisation-free survival. Eligible participants are nursing home residents with consent or proxy consent; those requiring immediate hospitalisation are excluded. Data are obtained from routine care and medical records, MGU documentation, structured assessments, and follow-up. Multilevel Poisson regression and interrupted time series analysis will be used. The study was approved by the Ethics Committee of Saarland (AZ 159-21) and conducted in accordance with the Declaration of Helsinki.

The MGU is a mobile diagnostic unit providing on-site diagnostics in nursing homes. It includes a 32-slice (64 slice reconstruction) whole body CT scanner, digital X-ray, portable ultrasound, ECG, EEG, and point-of-care laboratory diagnostics. A physician and radiology technician perform diagnostics on-site. Results are transmitted via telemedicine to hospital specialists and communicated to the general practitioner for treatment decisions within 48 hours.

The cognitive performance assessment is carried out through subjective evaluation by the nursing home's nursing staff at day 180.

Quality of life (EQ-5D-5L)
EQ-5D-5L is a standardised measure of health-related quality of life developed by the EuroQol Group and assesses health status in terms of five dimensions of health. The five levels in each dimension are worded as (1) 'not /no problems', (2) 'slight problems', (3) 'moderate problems', (4) 'severe problems' and (5) 'unable to' (mobility, self-care, usual activities), 'extreme' (pain/depression), or 'extremely' (anxiety/depression). Minimum value: 1 (best outcome) Maximum value: 5 (worst outcome)
