High use of pain, depression, and anxiety drugs in hemophilia: more than 3000 people with hemophilia in an 11-year Nordic registry study.

BACKGROUND

Pain is a common feature of hemophilia, but prevalence of depression and anxiety is less studied. Registry data on prescription drugs can provide an objective measure of the magnitude of these complications.

OBJECTIVES

To identify treatment patterns of prescribed pain, antidepressant, and antianxiety medications compared with those of matched controls in 4 Nordic countries.

METHODS

The MIND study (NCT03276130) analyzed longitudinal individual-level national data during 2007-2017. People with hemophilia (PwH) were identified from National Health Data Registers by diagnosis or factor replacement treatment and compared with population controls. Three subgroups were defined by the use of factor concentrates and sex (moderate-to-high factor consumption (factor VIII [FVIII] use of ≥40 IU/kg/week or FIX use of ≥10 IU/kg/week), low factor consumption, and women including carriers).

RESULTS

Data of 3246 PwH, representing 30,184 person-years, were analyzed. PwH (including children and adults) used more pain, depression, and anxiety medications compared with controls. This was most accentuated in the moderate-to-high factor consumption group and notably also observed in men with low factor consumption and women including carriers, usually representing a milder phenotype. A higher opioid use was observed across all age groups: 4- to 6-fold higher in the moderate-to-high factor consumption group and 2- to 4-fold higher in the low factor consumption group.

CONCLUSION

The consistent higher use of pain, depression, and anxiety medications among PwH compared with population controls, regardless of age, sex, or factor consumption, in broad national data suggests a need for improved bleed protection and hemophilia care for all severities including mild hemophilia.
