RESUMO
Compared to idiopathic pulmonary arterial hypertension (IPAH), patients with portopulmonary hypertension (POPH) have worse survival. Health disparities may contribute to these differences but have not been studied. We sought to compare socioeconomic factors in patients with POPH and IPAH and to determine whether socioeconomic status and/or POPH diagnosis were associated with treatment and health-care utilization. We performed a cross-sectional study of adults enrolled in the Pulmonary Hypertension Association Registry. Patients with IPAH (n = 344) and POPH (n = 57) were compared. Compared with IPAH, patients with POPH were less likely to be college graduates (19.6% vs. 34.9%, p = 0.02) and more likely to be unemployed (54.7% vs. 30.5%, p < 0.001) and have an annual household income below poverty level (45.7% vs. 19.0%, p < 0.001). Patients with POPH had similar functional class, quality of life, 6-min walk distance, and mean pulmonary arterial pressure with a higher cardiac index. Compared with IPAH, patients with POPH were less likely to receive combination therapy (46.4% vs. 62.2%, p = 0.03) and endothelin receptor antagonists (28.6% vs. 55.1%, p < 0.001) at enrollment with similar treatment at follow-up. Patients with POPH had more emergency department visits (1.7 ± 2.1 vs. 0.9 ± 1.2, p = 0.009) and hospitalizations in the six months preceding enrollment (1.5 ± 2.1 vs. 0.8 ± 1.1, p = 0.02). Both POPH diagnosis and lower education level were independently associated with a higher number of emergency department visits. Compared to IPAH, patients with POPH have lower socioeconomic status, are less likely to receive initial combination therapy and endothelin receptor antagonists but have similar treatment at follow-up, and have increased health-care utilization.
RESUMO
OBJECTIVE: To assess interrater reliability of the New York Heart Association/World Health Organization functional classification as applied by clinicians (defined as both physicians and nurses in this article) to patients with pulmonary arterial hypertension (PAH). PATIENTS AND METHODS: Between March 16 and August 31, 2007, a survey that described 10 hypothetical patients was completed by physicians and nurses attending a conference on PAH. Results were subsequently validated with physicians and nurses who were contacted online through the Pulmonary Hypertension Association. Respondents were asked to assign each patient's functional class as they would normally in clinical practice. RESULTS: The functional class evaluations were completed by 113 clinicians, 87 (77%) of whom had participated in PAH trials; 106 (94%) reported using functional class when determining therapy. Clinicians reported a broad range of factors they considered when evaluating functional class, and their assessments of functional class varied widely. The intraclass correlation coefficient was 0.58 for the initial patient survey and 0.62 for the online survey. At best, one patient was ranked as either class II (by 60 clinicians [53%]) or class III (by 53 [47%]). Clinicians' rankings spanned at least 3 functional classes for each of the other patients. Equally divergent rankings were observed among nurses and physicians. Cluster analysis identified clinicians' tendencies toward "higher" or "lower" functional class rankings. Of the 113 clinicians, 101 (89%) thought that the patients described resembled those seen in their practices. CONCLUSION: Despite the wide use of the New York Heart Association/World Health Organization functional class in clinical care and as a research tool, interrater agreement may be inadequate. Efforts to promote a uniform approach to evaluating functional class might help to standardize PAH care and research.

The effect of the new lung allocation score on ranking of patients on the waiting list and the number of transplants performed is not known. We assessed this effect on our lung transplant program and conducted a simulation of lung transplants for the first few months of the new system, using the old waiting lists. Patients with idiopathic pulmonary fibrosis had improved rankings and patients with emphysema had worse rankings, but the number of transplants for each disease category did not change significantly compared with the simulated transplants.
