The clinical audit of vitamin D health promotion in one Australian general practice was undertaken by measuring health service use and serum 25-hydroxyvitamin D levels in 995 patients aged 45 to 49 years.
Over 3 years, 486 (51%) patients had a Medicare funded Health Assessment. More women (54%) were assessed than men (46%) p = 0.010. Mean 25-OHD was higher for men (70.0 nmol/l) than women (60.3 nmol/l) p < 0.001. More patients had their weight measured (50%) than 25-OHD tested (28%).
Among 266 patients who had a 25-OHD test, 68 (26%) had normal levels 80+ nmol/l, 109 (41%) were borderline 51-79 nmol/l, and 89 (33%) were low < 51 nmol/l. Mean 25-OHD was higher in summer (73.7 nmol/l) than winter (54.7 nmol/l) p < 0.001. Sending uninvited written information about 25-OHD had no effect on patients' subsequent attendance.
Health promotion information about vitamin D was provided to 50% of a targeted group of patients over a one-year period. Provision of this information had no effect on the uptake rates of an invitation to attend for a general health assessment.
