Abstract
In predialysis patients, the optimal treatment choices for controlling haemoglobin (Hb) are unknown, because targeting high Hb levels has negative effects--poorer survival--but possible positive effects as well--better health-related quality of life (HRQOL). Moreover, these effects may be different in specific subgroups (e.g. young versus elderly). In the PREPARE-2 follow-up study, incident predialysis patients were included (2004-2011) when referred to 1 of the 25 participating Dutch outpatient clinics. HRQOL was assessed at 6-month intervals with the short form-36 (SF-36) questionnaire [physical/mental summary measure and eight subscales (range 0-100)]. A linear mixed model was used to associate Hb [<11, ≥ 11 to <12 (reference), ≥ 12 to <13 and ≥ 13 g/dL] with HRQOL, stratified by prescription of anaemia medication (erythropoietin-stimulating agent (ESA)/iron) and age (young: <65 years and elderly: ≥ 65 years). Only elderly patients (n = 214) not prescribed ESA/iron and with a high Hb (≥ 13 versus ≥ 11 to <12 g/dL) had a statistically significant (P < 0.05) and/or clinically relevant (>3-5 points) higher physical [11.9, 95% confidence interval (CI) 1.7, 22.2] and mental (6.4, 95% CI -1.7, 14.6) summary score. High Hb was not associated with a higher HRQOL in elderly patients who were prescribed ESA/iron. However, only young patients (n = 157) prescribed ESA/iron and with a high Hb (≥ 13 versus ≥ 11 to <12 g/dL) had a higher physical (8.9, 95% CI 2.1, 15.8) and mental (6.2, 95% CI -0.4, 12.8) summary score. The association of Hb levels with HRQOL differs by age and use of ESA/iron medication on predialysis care. Therefore, medical care should aim for shared decision-making regarding the appropriate Hb target leading to more individualized care.
