QoL as determined by the Medical Outcome Study 36-item Short Form Survey (SF-36) was the main outcome measured.</p></div><div><h3>Results</h3><p>QoL outcomes were not lower in the classically more severe homozygous SS individuals when compared with the heterozygous SC patients. However, SF-36 scores were significantly lower in individuals using opioids daily compared with those who did not, in all age groups and for all diagnoses. When controlling for hydroxyurea use, the negative association between opioid use and QoL scores remained unchanged. QoL scores were significantly higher in those who were either on no medications or on hydroxyurea alone, as compared with those who were on opioids alone or on hydroxyurea and opioids concurrently. Disease severity scores were not different between medication groups.</p></div><div><h3>Conclusions</h3><p><span>SCD patients on daily opioids had poorer QoL scores than those who were not on opioids, independent of disease severity. Hydroxyurea had a positive impact on QoL, although that effect was not observed in patients also using chronic opioids.
