Vitamin d deficiency/insufficiency practice patterns in a veterans health administration long-term care population: a retrospective analysis.
OBJECTIVE
To evaluate the prevalence of vitamin D deficiency/insufficiency in long-term care patients at a Veterans Health Administration (VHA) hospital and to assess treatment and follow-up of low vitamin D levels.


METHODS
Observational cohort study.


METHODS
VA hospital extended care center (ECC).


METHODS
2218 ECC patients between January 2001 and December 2006 were screened.


METHODS
Serum 25-hydroxyvitamin D (25[OH]D) level, vitamin D therapy regimen, time to follow-up, documented adverse event to vitamin D therapy.


RESULTS
Of 2218 patients admitted to the ECC during the study period, 229 (10%) had a vitamin D level measured. Among these 229 patients, 49% were vitamin D sufficient (25[OH]D > or =30 ng/mL), 14% were insufficient (25[OH]D=21-29 ng/mL), and 37% were deficient (25[OH]D < or =20 ng/mL). Sixty-nine percent of patients with low vitamin D levels received some form of vitamin D therapy, whereas 43% received treatment as well as follow-up evaluation of vitamin D status within 3 months. Only 13% received a formulation of vitamin D appropriate for the severity of their deficiency/insufficiency with concurrent calcium supplementation and had a repeat vitamin D level within 3 months.


CONCLUSIONS
Vitamin D levels were measured infrequently in long-term care patients. Among those monitored, the rate of vitamin D deficiency/insufficiency is high. Few patients with low vitamin D status received proper treatment and follow-up. These data support the need to educate physicians regarding the high prevalence of vitamin D insufficiency/deficiency among long-term care patients to ensure that patients with low vitamin D levels are identified and treated appropriately.
