Abstract
Introduction
Enhanced care units (ECU) are a novel concept, targeting the gap between ward-level and critical care. They care for patients requiring intensive medical or nursing care, who may not require, desire, or be suitable for, escalation above ward care (Society of Acute Medicine and Intensive Care Society, 2022). The ECU at Barnet Hospital opened in March 2022, and, because of the local population demographic, admits a high number of older patients living with frailty. We aimed to assess the performance of the ECU for this subset of patients.
Methods
A retrospective audit of electronic records of 75 randomly selected patients admitted to ECU between March and August 2023. Data were gathered on Clinical Frailty Score (CFS) at baseline, comorbidity, escalation status, APACHE II illness severity score, and outcome measures.
Results
The majority of patients in the sample, 52 of 75 (69.3%), were over 65 years of age with an average of 69.1 years. Baseline frailty score was high, with a modal CFS of 6. Of these patients, 32 (61.5%) had a DNACPR, and 16 (30.8%) had treatment ceiling at ECU level. Illness severity was similar across CFS groups, with a mean APACHE II score of 15.2 (representing a 25% mortality risk). Overall mortality in the over 65s was 23.1% (12/52), without significant change when stratified by CFS. Mortality in the under 65s was 8.7% (2/23).
Conclusions
Acutely unwell patients with frailty may benefit from ECU level care. In our centre, we found no significant increase in mortality linked to a higher frailty score. We suggest that this may represent good case selection by clinicians experienced in working with frailty: admitting patients with more reversibility and targeting therapies towards reversible causes. Limitations remain, especially in assessing illness severity, as the assessment tools are not targeted to this cohort.
