Summary of Research Project:
Historically, pulmonary hypertension (PH) in children was associated with dramatically shorter lifespans. Drug development has reduced this risk, but children with PH experience chest pain, exercise intolerance, and fainting spells that are an obstacle to participating in and enjoying the activities that define childhood. PH symptoms, chronic drug treatment and intense follow-up are all stresses on patient and family. The effect of this on children with PH has not been studied, as it is not recorded in doctors’ notes or in clinical trials. Patient-reported outcomes (PRO) identify aspects of the patient experience that are informative about health and are expressed in terms that make sense to and are important to patients and their families. PRO can then be measured and used in both research and clinical care. Health related quality of life (HRQOL) is one such PRO, measuring whether a person can participate in and enjoy age appropriate activities. Having more severe PH (and more severe symptoms) likely reduces HRQOL, but other factors likely also influence it. These are 1) presence of anxiety or depression, 2) patient’s outlook on life (in terms of optimism and resilience), and 3) parental stress levels. These factors can be measured with research questionnaires and combined with data collected during routine medical care to provide a complete assessment of the factors influencing HRQOL. We plan to study which of these factors affects HRQOL in a group of children with PH. Identifying factors that influence HRQOL is important because, doing so might make it possible to intervene on one or more of them and improve the health and well-being of children with PH, independent of the severity of the child’s disease.
