RT Journal Article SR Electronic T1 Symptom severity and its effect on health-related quality of life over time in patients with pulmonary hypertension: a multisite longitudinal cohort study JF BMJ Open Respiratory Research JO BMJ Open Resp Res FD British Thoracic Society SP e000263 DO 10.1136/bmjresp-2017-000263 VO 5 IS 1 A1 Janelle Yorke A1 Christi Deaton A1 Malcolm Campbell A1 Linda McGowen A1 Paul Sephton A1 David G Kiely A1 Iain Armstrong YR 2018 UL http://bmjopenrespres.bmj.com/content/5/1/e000263.abstract AB Introduction The aim of this cohort study was to examine health-related quality of life (HRQoL) and symptomatology in patients with pulmonary hypertension (PH) and explore factors that influence its evolution over time.Methods A prospective longitudinal multisite cohort study. Participants were recruited from specialist UK PH centres and completed a questionnaire pack at baseline, 6, 12 and 18 months to assess HRQoL (emPHasis-10), dyspnoea, fatigue, sleep, anxiety and depression.Results 185 patients entered the study at baseline and 126 (68%) completed month 18. At baseline, patients had significant impairment of HRQoL, anxiety, depression, dyspnoea and severe fatigue. No significant changes, apart from a reduction in the Hospital Anxiety and Depression Scale-Anxiety score (P=0.04), were observed over 18 months. Depression and dyspnoea were predictors of HRQoL (P=0.002 and P=0.03, respectively). Oxygen use was also associated with diminished HRQoL and increased symptom severity.Conclusion Patients with PH experience high levels of symptom severity and the negative impact on HRQoL was unchanged over time. The use of oxygen therapy, in particular, was associated with a significant impact on HRQoL. Further study of factors impacting HRQoL and interventions that target a combination of physiological and psychosocial consequences of living with PH are needed.
