Dear Editor,
There is growing awareness of the potential challenges that may be associated with life after ICU survival. Post-ICU hospital readmission, long-lasting functional disability and cognitive impairment have been reported and are associated with reduction in quality of life and substantial utilisation of healthcare resources [1, 2]. The impact of such post-ICU sequelae urges us to develop smart strategies for post-ICU rehabilitation, aiming for an immediate and continuous process of physical and psychological stimulation of individual ICU patients, beyond physical and virtual institutional walls.
An essential component in this chain of events is the transfer from the ICU to the next care facility. Traditionally ICU patients are referred to a hospital ward. However, bridging the gap between the ICU and hospital wards has been cumbersome in long-stay ICU patients. Despite the widespread introduction of a large variety of step-down units, its results are far from unequivocal; for individual patients the gap remains unbridgeable, fuelling additional initiatives, including rapid response teams and liaison nurse services [3]. However, the majority of these interventions are technology-centred, system-oriented rather than patient-oriented, and none of these units are (additionally) equipped for rehabilitation.
Nursing-home rehabilitation units (NRU) traditionally incorporate multidisciplinary assessment of functional dependency, including physical, psychological and social deficits. A simultaneous goal setting for a variety of functional domains will be formulated, as a basis for tailor-made coordinated rehabilitation [4]. We hypothesized that, despite limitations in medico-technical support, direct step-down to an NRU could be a safe and suitable alternative for a specific group of severely disabled ICU patients.
To this end we performed a single-centre before–after study. Patients with an ICU length of stay (LOS) longer than 48 h, a hospital ward as first post-ICU step-down unit and an NRU as final destination were selected (indirect transfer group, ITG). In the second phase, after an intervention to redirect patient flow, patients with an ICU LOS longer than 48 h and a direct transfer to an NRU were prospectively included (direct transfer group, DTG). Baseline characteristics, LOS in subsequent treatment facilities, readmission rate, final discharge status and consecutive Barthel indices (BI) were recorded [5]. Non-parametric tests were applicable.
In a 5-year period we included 31 patients in the ITG and 24 patients in the DTG, representing 0.7 % of the total ICU population. At ICU discharge BI did not differ between groups [data are presented as median (IQR); ITG 2 (0–2) vs. DTG 2 (1–6), p = 0.15]. Severity of illness, days of mechanical ventilation and LOS ICU were significantly higher in the DTG (ESM). Primary endpoint, the BI at NRU discharge, was not different between groups [ITG 16 (14–18) vs. DTG 16 (11–18), p = 0.50; Fig. 1]. However, LOS post ICU was significantly longer in the ITG [ITG 74 (58–106) vs. DTG 46 (19–117), p = 0.03; Fig. 1]. In addition, hospital readmission rates, mortality and final discharge status did not differ between groups (ESM).
Our data suggest that an NRU as the first post-ICU step-down facility in functionally dependent patients may be associated with equal functional outcome in a shorter time frame, as compared to the traditional pathway. We hope this may fuel initiatives to focus on functional rather than medico-technical support in this specific group of long-stay ICU patients.
