Swiss Study on Vitamin D and Calcium in Nursing Homes

Residents of nursing homes are endangered by malnutrition and vitamin D deficiency. Our study checks compliance with Swiss federal recommendations on vitamin D and calcium supplementation among residents of a Swiss nursing home. A peer physician-applied recommendation on compliance with the federal recommendations with individual evaluation of the residents will be sent to the physicians in care. After one year, data will be collected again.

About this study

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.

Treatment and study plan

peer physician-applied recommendation to the physicians

Behavioral

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.

Primary outcomes

  1. 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.

Secondary outcomes

  1. 25-hydroxyvitamin D serum levels

    Time frame: up to 12 months

    We measure 25-hydroxyvitamin D serum levels among the residents.

  2. 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.
