Clinical Utility of Patient-Reported Outcome Instruments in the Management of Pulmonary Hypertension

Despite the greater sensitivity and specificity of disease-specific patient-reported outcome measures (PROM) to detect clinical change, only recently have such instruments been developed for pulmonary hypertension (PH), specifically pulmonary arterial hypertension (PAH) and chronic thromboembolic disease (CTEPH). Although these valuable tools are now being incorporated into clinical studies of PH, they have not yet reached widespread integration into routine clinical care.In this systematic review, we assess the psychometric properties of PROM developed for PH, compare PROM with other clinical outcomes in PH, and address the utility of PROM in clinical care.The authors performed a systematic search of papers published between January 1, 2006, and October 1, 2022, using the MEDLINE database to identify PROM developed and validated for PH. The identified PROM were found to have been developed only in groups with PAH and CTEPH. The authors evaluated the identified instruments according to established psychometric criteria. An additional search was performed to identify randomized controlled trials (RCTs)∖utilizing these PROM for comparison with clinical outcomes.From 527 papers retrieved, a total of 35 PROM were identified. Of these, 5 disease-specific instruments were included in the final analysis. While both Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) and XXX (emPHasis-10) performed well in patients with PAH and CTEPH with regard to their psychometric properties, emPHasis-10 demonstrated superior feasibility for use in clinical practice due to its concise format. The Pulmonary Arterial Hypertension-Symptoms and Impacts Questionnaire performed well in the authors' analysis, though additional data is needed regarding interpretability and feasibility.EmPHasis-10 demonstrated strong psychometric properties and the greatest feasibility for clinical use. Further study assessing the integration of PROM into routine clinical care for PH is needed.
