Direct discharge from the intensive care unit improved patient flow in a resource-pressured health system

Critical care practice is constantly evolving. Pressures for bed availability in publicly funded healthcare systems have led to an increase in patients delayed in their discharge from critical care to the wards. This has resulted in more patients discharged directly home (DDH) from the intensive care unit (ICU). However, few formal pathways for DDH exist. We have performed a retrospective audit of the patients discharged home from our unit in the largest tertiary referral hospital in the Republic of Ireland from 2017 to 2022 to investigate their characteristics and the safety of this practice, given the understandable patient safety concerns raised. Results In total, 84 patients have been DDH from our unit between 2017 and 2022 from a total of 4747 patients. The overall rate of DDH increased year on year, and the vast majority of these patients were initially admitted from the emergency department or following elective major surgery. Most patients had an APACHE score of less than 11 points, and the majority were admitted for less than 3 days, with single organ failure. There was a gender divide, as greater than 60% of the patients admitted were male, with a mean age of 44. Conclusion DDH has been an important tool in improving patient flow through the hospital, avoiding unnecessary de-escalation to the ward for a select group of critical care patients. The re-admission rate in the year post-ICU discharge was very low, showing that DDH has not adversely impacted patient safety.
