National Pulmonary Hypertension Audit

The Pulmonary Hypertension Audit measures the quality of care, activity levels, access rates and patient outcomes of pulmonary hypertension services in centres designated by the National Commissioning Group.

What does it measure?

The audit assesses the quality of care, activity levels, access rates and patient outcomes.

Outcome measures include:

  • pulmonary function tests
  • six minute walk (distance in metres)
  • echocardiography - reduction in peak pulmonary artery pressure
  • chest x-ray - reduction in cardiothoracic ratio
  • quality of life measures (v papworth protocol)
  • survival at 6 months and 1 year on prostaglandins and analogues


Information from the audit is used by clinicians and commissioners to inform clinical practice, service development, improvement and commissioning activities.

The audit helps to inform pulmonary hypertension services which are nationally commissioned by the National Commissioning Group (NCG), which oversees the national commissioning of highly specialised healthcare services.

Wherever possible patients should be treated by one of the designated centres. In January 2003, pdf icon national pulmonary hypertension standards [190kb] were produced for this nationally designated service.

All centres are required to meet the minimum standards for specialist units. The standards focus on clinical standards, outcome measures, level of activity and case mix.

Who manages the audit?

NHS Digital is working in collaboration with senior clinicians from the specialist centres. The National Pulmonary Hypertension Audit is commissioned by NHS England.
