Association of iron supplementation with risk of transfusion, hospital length of stay, and mortality in geriatric patients undergoing hip fracture surgeries: a meta-analysis.
Abstract
To assess the efficacy and safety of iron supplementation for perioperative anemia in geriatric patients with hip fracture. A systematic search was conducted for studies published using PubMed, EMBASE and Cochrane Library Databases that compared iron supplementation with placebo in patients undergoing hip fracture surgery. The outcomes were blood transfusion rate and volume, length of stay, infection and mortality (last follow-up). Sub-group and sensitivity analyses were performed in cases of substantial heterogeneity. The meta-analysis (6 studies: 1201 patients) indicated that iron supplements were not associated with reducing blood transfusion rate (OR 0.92, 95% CI 0.60-1.41; P = 0.69), but high heterogeneity (I2 = 61%) was detected and a significant association was found in sensitivity analysis of four studies (n = 637; OR 0.68, 95% CI 0.49-0.95; P = 0.02). A significant reduction was detected in transfusion volume (two studies: n = 234; MD - 0.45 units/patient, 95% CI - 0.74 to - 0.16; P = 0.002), hospital stay (five studies: n = 998; MD - 1.42, 95% CI - 2.18 to - 0.67; P = 0.0002) and caused no increased risk of mortality (five studies: n = 937; OR 0.94, 95% CI 0.65-1.36; P = 0.76) and infection (four studies: n = 701; OR ...Continue Reading

Anemia
Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
