The treatment of vascular malformations is aimed at improving symptoms; therefore, evaluating treatment from the patient's perspective is crucial. In this study, we report the development of the patient-reported outcome measure, the OVAMA Treatment Outcome questionnaire, which assesses treatment and outcomes in patients with vascular malformations. Additionally, we found that the OVAMA Treatment Outcome questionnaire has good content and construct validity.
Stor et al. (Thu,) studied this question.
