Background:
People with severe multiple sclerosis (PsMS) have multidimensional, complex needs. COCOS-MS is an exploratory study of the effect of cross-sectoral care and case management (CCM) on these patients' quality of life, palliative care needs, and psychological distress, as well as caregivers' burden.
Methods:
We conducted a randomized, controlled, phase II trial (DRKS00022771) with two parallel treatment arms: standard care versus CCM in addition to standard care over a 12-month period. A trial-specific CCM manual was used. The target variables were recorded in standardized fashion at baseline (T0) and every three months thereafter (T1 until the end of the intervention at T4, then T5 three months after the end of the intervention to determine sustainability). The primary endpoint was the change in the patients' quality of life (HALEMS) from baseline to month 12 in a group comparison. A modified intention-to-treat (mITT) was performed based on a mixed linear model with repeated measures over time (ARH1-structured covariance matrix). Values of p less than 0.05 were considered significant.
Results:
80 PsMS were randomly assigned 1:1 to one of the two treatment arms (male: female 1:2, median age 55 years [IQR 49-62], EDSS 6.5 [6-7.5], dropout rate 10%). There was no significant improvement in HALEMS after one year (T4) in the group comparison (-0.08 [-0.31, 0.15], p = 0.503; NNT = 22). Secondary endpoints such as subjective health status, psychological distress, and palliative care needs showed a clear response at the end of the intervention. After the intervention ended, the values approached the baseline level.
Conclusion:
The primary endpoint did not reach significance in this health services research feasibility study. For further development of the study design, the focus will be on the psychological and palliative factors in which PsMS-a reference group for long-term neurological conditions-were found to benefit from the CCM.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
