Vitamin D Insufficiency inVestigation Among hospitaLizeD Inpatients
Hypovitaminosis D is common in the adult population, it affects at least 1 billion people worldwide, and in particular 80% of the French population according to the National Institute for Public Health Surveillance. Hypovitaminosis D is accompanied or complicated by deleterious health manifestations such as bone, immune and cancer diseases, neuromuscular disorders and a propensity to fall, for example. Hypovitaminosis D has also been associated with more complicated care pathways (increase in the severity of the reason for hospitalization, length of hospitalization, risk of in-hospital death). Prevention of these clinical events depends on correcting vitamin D status.
In sick, dependent or fragile adults, natural intakes are generally insufficient. It is indeed accepted that hypovitaminosis D may not be treated effectively by dietary measures or by simple exposure to the sun in French latitudes. Drug supplementation is therefore necessary, with the objective of achieving a target concentration of circulating 25-hydroxyvitamin D (25 (OH) D) of 75 nmol / L (30 ng / mL) in this population.
Vitamin D supplementation, when properly conducted, corrects hypovitaminosis D, and has been associated with improved prognosis, especially life-saving, in therapeutic trials versus placebo. Such results lead the investigators to suggest that the identification and correction of hypovitaminosis D in hospitalized patients could represent a simple, effective and inexpensive strategy for improving hospital care pathways. In this perspective, the first step is to determine the prevalence, severity and clinical profile of hospitalized patients with hypovitaminosis D, as well as their course of care. To the investigators knowledge, there are no large-scale studies based on real-life data on this subject.
