Given the high prevalence of anemia in LTC and its observed associations with specific clinical events, the current study evaluates in LTC residents the association of anemia and Hb level with a physical functioning index, the Carpenter et al. ADL score [26], and with an HRQOL index, the Minimum Data Set Health-Status Index (MDS-HSI) [27]. The gene discussed is GSTM1; the disease is anemia.
