We set out to determine standards that would enable the identification of persons at risk of Vitamin D (VitD) deficiency in our ward; the prevalence of deficiency in at risk patient group on a 25-bedded ward (Brunswick). Deficiencies were identified, managed according to local guidelines and care plans were updated to reflect this change.

Low VitD levels have been associated with depression, psychosis, schizophrenia, suicidality, treatment resistance and poor coping. However, serum VitD levels is not a routine investigation on inpatient psychiatric admissions. Factors associated with VitD deficiency include prolonged stay in inpatient units with limited exposure to sun; Inpatients’ diet; Self-neglect and social isolation.

Criteria for identifying patents who may be at increased risk was agreed.

These patients were approached, and consented to screening. Results of the investigation were discussed with patients and actioned according to need. Study period May 2015–July 2015.

We were unable to identify any criteria in use for identifying persons at risk in psychiatric services. The following criteria were agreed: Hospital stay for > 2 months and limited opportunities of leaving the ward (Detention); Transfer from another unit with a total of hospital stay > 2 months; Admission from the community with severe depression or history of social isolation.

7 patients (28%) were identified to be at increased risk. Of this, 6 patients (85.7%) were deficient and another 1 (14.3%) had insufficient level. Management was instituted.

If indicated, psychiatrists ought to consider monitoring VitD levels during inpatient stays and managing as appropriate.
