P117 Changes in prescription of home non-invasive ventilation (NIV) in Southern Adelaide Local Health Network (SALHN) from 2016 – 2020

Abstract

Abstract Background Long term NIV is established therapy for patients with chronic type 2 respiratory failure (T2RF) due to neuromuscular disorders and obesity hypoventilation syndrome (OHS) without significant OSA. There is emerging evidence that COPD patients with T2RF also benefit from NIV. In our centre, there appears to be an increase in the prescription of long term NIV to patients over time, with 60% of all active long term NIV patients commencing therapy from 2017 onwards. In this study we will determine if (i) there has been increased provision of long term NIV to ward patients recovering from acute T2RF, (ii) there has been an increase in patients with COPD and T2RF commenced on long term NIV, (iii) there are patients with OHS and comorbid OSA who can be changed from NIV to CPAP and (iv) there is adequate follow up for patients who initiated NIV in the ward acutely. Methods Retrospective, observational study using a pre-existing database of all current and previous patients commenced on NIV from July 2016 to July 2020. Progress to date All active long term NIV patients have been identified and a database (n= 220) created containing all relevant information including date and place of NIV initiation and indication. Intended outcome and impact This audit will objectively assess the growth of our NIV service to facilitate better allocation of resources. It will also determine if our commencement and management of those on long term NIV is aligned with current evidence and best practice guidelines.
