Distress among patients with congenital bleeding disorders followed at a comprehensive HTC was high and similar to that reported among patients with cancer. Future research should determine whether distress impacts clinical outcomes in patients with bleeding disorders as demonstrated in other chronic disorders.
Distress effects are widely examined in cross-sectional studies with less known about effects on future health. This review summarizes distress impacts on health among adults in prospective studies and describes available distress measurement tools. Four inter-disciplinary databases were searched. Effects of distress on mortality and other outcomes were reviewed and estimated in a meta-analysis. A total of 19 studies were assessed which incorporated 10 distress tools. Distress had a detrimental effect on health regardless of the population studied, distress tool used, and health outcome examined. There was an increased mortality risk among those reporting high versus low distress (pooled hazard ratio (95% confidence interval) = 1.29 (1.15–1.46)).
Introduction
The Patient‐Reported Outcomes Measurement Information System (PROMIS) provides measures of health status that assess physical, mental and social well‐being from the patient perspective. PROMIS measures are used in clinical practice and research across various patient populations but are not yet validated among patients with haemophilia.
Aim
Evaluate the sensitivity of PROMIS to indicators of haemophilia clinical severity and compare PROMIS measures to those from other PRO instruments.
Methods
Male adults with haemophilia (n = 115) completed the PROMIS‐29 short form which includes 4 questions for each of 7 domains: depression, anxiety, ability to participate in social roles and activities, physical function, pain interference, fatigue and sleep disturbance. Participant responses for each domain were scored on a T‐score metric with a mean of 50 and a standard deviation of 10 based on the original PROMIS reference sample of US adults. Participants also completed other generic and haemophilia‐specific health‐related quality of life questionnaires.
Results
Participants who experienced higher pain and depression levels reported significantly worse health in every PROMIS domain compared with their peers. Those who had recently needed to use crutches, visit an emergency department or were currently unemployed or disabled also reported poor PROMIS scores on most domains. Construct validity was supported by correlations between PROMIS domain scores and domain scores reported using the EQ‐5D‐5L and Haem‐A‐QoL.
Conclusion
The PROMIS instrument provides a potentially valuable tool to evaluate the impact of haemophilia and suggests usefulness in research and clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
