|Aging Vitamin Deficiency||Behavioral: peer physician-applied recommendation to the physicians|
The investigators plan to get a complete sample of all inhabitants, so the only inclusion criterion is to get an informed consent either from the residents or from their relatives. The following data will be recorded: Year of birth, gender, height, weight, blood pressure and heart rate, daily calcium intake from diet, nursing home scales on pain, depression, dementia and activities of daily life, date of entry to the home, diagnosis and medication lists. From a venous blood sample the investigators get: calcium, phosphate, albumin, creatinin, 25-hydroxyvitamin D, parathormone (intact).
Primary endpoint: Proportion of medication lists of residents complying with federal recommendation on vitamin D and calcium supplementation.
Secondary endpoints: 25-hydroxyvitamin D levels, effect of an intervention with a nursing home-applied recommendation to the physicians.

Experimental: Entire group
A peer-applied guideline will be applied to the physicians.
Behavioral: peer physician-applied recommendation to the physicians
The peer physician-applied recommendation will include scientific information, practical recommendations to correctly supplement with calcium and vitamin D and a list of individual appraisals of the prescribed supplements among the residents.
- Proportion of compliance with federal recommendations [ Time Frame: up to 12 months ]We register the proportion of residents those calcium and vitamin D supplementation complies with Swiss federal recommendation.
- 25-hydroxyvitamin D serum levels [ Time Frame: up to 12 months ]We measure 25-hydroxyvitamin D serum levels among the residents.
- Effect of nursing home-applied recommendations to physicians [ Time Frame: up to 12 months ]We check the effect of a nursing-home-applied recommendation to the physicians in care of the residents concerning correct supplementation with vitamin D and calcium on a) proportion of compliance with federal recommendations, b) 25-hydroxyvitamin D serum levels and c) medication costs.
