[Holistic clarification of the need for intervention at the interface of rehabilitation and occupational medicine when work participation is at risk].

Introduction: For employees whose work participation is at risk, a comprehensive and workplace-oriented diagnosis is required in order to understand the health problems and to support affected persons with individual solutions. We developed a novel diagnostic service to ensure work participation that combines rehabilitative and occupational health medicine. The aim of this feasibility study was to evaluate the implementation and to analyze changes in health and working ability.

Methods: The observational study (German Clinical Trials Register: DRKS00024522) included employees with health restrictions and limited working ability. Participants received an initial consultation from an occupational health physician, a 2-day holistic diagnostics work-up at a rehabilitation center and up to four follow-up consultations. Questionnaire data collected at the initial consultation and at the first and last follow-up consultations included subjective working ability (0-10 points) and general health (0-10).

Results: Data from 27 participants were analyzed. The participants were 63% female and on average 46 years old (standard deviation, SD = 11.5). From the initial consultation to the final follow-up consultation, participants reported improvement in their general health (difference = 1.52; 95% confidence interval. CI: 0.37-2.67; d = 0.97).

Discussion and conclusion: The model project GIBI offers low-threshold access to a confidential, comprehensive and workplace-oriented diagnostic service to support work participation. Successful implementation of GIBI requires intensive cooperation between occupational health physicians and rehabilitation centers. To evaluate the effectiveness, a randomized controlled trial (n = 210) with a waiting list control group is currently underway.
