Introduction: Self-perceived health-related quality of life (HRQoL) of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) and their experience with the care received are important for improving their management. We conducted a study to assess both patient-reported outcomes (PROs) and how they interrelate.
Methods: This was a cross-sectional, observational study of consecutive patients with PAH and CTEPH attending pulmonary hypertension (PH)-specialized units at 25 hospitals in Spain. PRO measurements used included CAMPHOR/EQ-5D-5L questionnaires (HRQoL) and IEXPAC (healthcare experience). Patient characteristics were collected. Relationships were analysed with Pearson's correlation coefficient and linear regression analyses.
Results: A total of 185 patients with PAH and 93 patients with CTEPH aged 54.4 ± 14.4 and 64.8 ± 13.4 years were included: 63.6% and 72% were functional class (FC) I-II; median time from diagnosis was 3 and 2 years, respectively. Most patients with PAH received combination oral therapy. CAMPHOR scores indicated moderate-to-high impairment in the "activity" scale (PAH 21.6 ± 6.8; CTEPH 21.0 ± 6.3). EQ-5D-5L index and visual analogue scale (VAS) score (PAH 0.59 ± 0.15 and 65.55 ± 21.54; CTEPH 0.59 ± 0.13 and 66.95 ± 18.71, respectively) indicated moderate HRQoL impairment. HRQoL was mostly affected by FC. IEXPAC scores (PAH 7.08 ± 1.56 and CTEPH 7.13 ± 1.61) indicated good healthcare experience. In patients with PAH, the CAMPHOR "symptom" and "QoL" domains inversely correlated with the IEXPAC "patient self-management" factor.
Conclusion: In patients with long-standing PAH and CTEPH with good disease control, functional limitations greatly impact HRQoL while symptoms and generic QoL were less affected. Healthcare received was perceived as good; however, use of information and communication technologies, patient associations and promotion of self-management should improve for enhanced patient experience.
