Pertinence du dosage systématique des vitamines B9 et B12 en court séjour gériatrique

Abstract : Folate and vitamin B12 deficiencies are particularly prevalent in elderly, and are responsible for impairing quality of life and increasing mortality. This study aimed to assess whether systematic dosage of vitamins B9 and B12 detects more deficiencies than dosage after clinical ou biological sign. 2 342 patients were hospitalized in geriatric short stay units in Bordeaux during year 2018. After having excluded patients under 75 years old, 2 055 patients were included. Then patients were separated in two groups, « systematic dosage » and « non-systematic dosage », depending on the unit they were hospitalized in. Datas concerning vitaminic status, clinical symptoms, medical history and some biological values were collected from medical and nursing records. We found a total of 175 vitamin deficiencies, with 82 cases (14,1%) in the « systematic dosage » group and 93 cases (6,3%) in the « non-systematic dosage » group. The difference was significant (X² = 32,8 ; p < 0,001). Systematic dosage therefore detects more deficiencies in vitamins B9 and B12. More studies are required to confirm these results and to determine the effects of supplementation on quality of life and survival.
