Retrospective service evaluation of a specialist weaning unit

Specialist weaning units (SWUs) aim to liberate patients with complex weaning failure from mechanical ventilation and facilitate their discharge from the ICU. This retrospective service evaluation reports the outcomes of a SWU at Wythenshawe Hospital, Manchester between 2017 and 2019. In total, 75.0% (n = 33/44) of patients survived to hospital discharge. Of these patients, 72.7% (n = 24/33) were self-ventilating. Overall, 1-year survival was 68.2% (n = 30/44), whilst 5-year survival was 52.3% (n = 23/44). Whilst this study is relatively small, these findings are encouraging and further support the case for SWUs.
