A short intervention targeting psychosomatic care in older adults with complex health care needs- results of a randomized controlled trial.

OBJECTIVE: The aim of this randomized controlled trial (RCT) was to assess the efficacy of a short intervention targeting psychosomatic care in older adults with complex health care needs.

METHODS: Participants were recruited in the frame of the 11-year follow-up of a large population-based study by means of the INTERMED interview. The INTERMED-interview is an integrative assessment method to identify bio-psycho-social health care needs. Persons with high health care needs (interview score ≥ 17) were invited to take part. Participants were randomized with a 1:1 ratio to a control and an intervention group. The intervention group received a home visit conducted by a doctor trained in psychosomatic medicine. The primary hypothesis stated that the intervention group would have a better outcome with respect to health related quality of life (HRQOL) measured by the 12-Item Short-Form Health Survey (mental component score, MCS) six months after randomization (T1). Secondary outcomes were physical HRQOL, health care needs, depression, anxiety, and somatic symptom severity.

RESULTS: In total, 175 participants were included. At the three-year follow-up (T2), 97 participants (55.4 %) were included. At T1, we did not find a difference regarding MCS between the intervention and control groups. At T2, the intervention group showed significantly lower health care needs compared to the control group. Regarding HRQOL, depression, and somatic symptom severity the two groups did not differ at T2.

CONCLUSIONS: The primary hypothesis was not confirmed. However, results indicate that a short intervention with complex patients could lead to reduced bio-psycho-social health care needs.
