Outpatient specialist clinics for pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension in the Nordic countries.

Pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension are rare conditions that require complex interventions by multidisciplinary teams. The European Society of Cardiology (ESC)/the European Respiratory Society (ERS) 2015 guidelines included recommendations for pulmonary hypertension (PH) referral centers including minimum number of patients, staff, facilities, and network. The aim of the present study was to investigate how the PH-specialist centers in the Nordic countries are presently organized. A descriptive, questionnaire was sent to all PH-specialist centers in the Nordic countries in 2018. Sixteen of 20 PH-specialist centers completed the questionnaire. Seven centers (43%) followed less than 50 patients and three centers (19%) followed 125 patients or more. All had a physician or nurse attending or available at the clinic and eight had support staff such as physiotherapists, counsellors, dieticians, or psychologists directly connected to the center. Twelve centers were available by telephone five days or more per week. Nine centers offered a nurse-led outpatient clinic and of those, six had nurses delegated to make protocol-led changes in pulmonary arterial hypertension-specific treatment. Half of the centers had cooperation with a patient organization. All centers except one used international guidelines to guide care and treatment. More than half of the Nordic PH-specialist centers adhered to the ESC/ERS 2015 guidelines recommendations for volumes and staff in 2018, but there is potential for improvement. However, when formulating recommendations of patient volumes in guidelines, the situation for the geographical large but sparsely populated Nordic countries needs to be considered.
