What this trial studies
This is a prospective, single-center registry enrolling adult patients undergoing vitamin D supplementation at the IRCCS Ospedale San Raffaele Endocrinology outpatient unit. About 1,000 patients will be enrolled and clinical, laboratory, and medical history data will be collected during routine visits according to standard diagnostic and therapeutic protocols. Treatments are prescribed as part of usual care, with the registry passively recording formulations, dosages, outcomes, and potential risk factors. Data collection will continue through 2029 with follow-up data retained for up to ten years to describe epidemiological trends and management patterns for hypovitaminosis D.
Who should consider this trial
Good fit: Adults aged 18 and over seen at the San Raffaele Endocrinology outpatient clinic who are starting or receiving any vitamin D supplementation and can provide informed consent.
Not a fit: People under 18, individuals unable to provide informed consent, and patients treated outside San Raffaele or not receiving vitamin D supplementation are not eligible and unlikely to benefit from this registry.
Why it matters
Potential benefit: If successful, the registry could help clinicians target vitamin D prescribing more effectively and better identify patients at risk of deficiency.
How similar studies have performed: Similar observational registries and cohort studies on vitamin D have generated useful epidemiological and risk-factor data but cannot prove causality for clinical outcomes.
