A cross-sectional study of Swiss ambulatory care services use by multimorbid patients in primary care in the light of the Andersen model.

Multimorbid patients in primary care reported high use of ambulatory healthcare services variably associated with the Andersen model's factors: healthcare use was associated with objective medical needs but also with contextual or individual predisposing or enabling factors. These findings emphasize the importance of adapting care coordination to individual patient profiles.
