Intermediate care units (IMCUs) have become increasingly important in the care of critical and semi-critical patients, particularly during the COVID-19 pandemic. However, there is still no clear definition of their structural characteristics, specialties, types of patients, and the benefits they provide. The aim of this work is to describe the current state of implementation and operation of IMCUs in hospitals and patient care. To achieve this goal, a systematic review was conducted in the Web of Science, Scopus and CINAHL databases, along with a hand search. The research yielded 419 documents, of which 26 were included in this review after applying inclusion and exclusion criteria. The results were highly diverse and were categorized based on the following topics: material resources, human resources, continuity of care, and patient benefits. Despite the different objectives outlined in the studies, all of them demonstrate the numerous benefits provided by an IMCU, along with the increased relevance of this type of unit in recent years. Therefore, this systematic review highlights the benefits of IMCUs in the care of critical patients, as well as the role of health workers in these units. [ABSTRACT FROM AUTHOR]

Purpose: To refine the admission criteria of the Acute Geriatric Community Hospital (AGCH) by defining its target group boundaries with (geriatric) hospital care and other bed-based intermediate care models in the Netherlands., Methods: A qualitative study consisting of a three-phase refinement procedure with case vignettes. Physicians, medical specialists, nurse practitioners, and physician assistants in hospitals (n = 10) or intermediate care facilities (n = 10) in the Netherlands participated. They collected case vignettes from clinical practice (phase one). The referral considerations and decisions for each case were then documented through surveys (phase two) and two focus groups (phase 3). For thematic data analysis, inductive and deductive approaches were used., Results: The combination of medical specialist care (MSC) and medical generalist care (MGC), is unique for the AGCH compared to other intermediate care models in the Netherlands. Compared to (geriatric) hospital care, the AGCH offers a more limited scope of MSC. Based on these findings, 13 refined admission criteria were developed such as 'The required diagnostic tests to monitor the effectiveness of treatment are available at the AGCH'. Besides admission criteria, additional clinical and organizational considerations played a role in referral decision-making; 10 themes were identified., Conclusion: This case vignette study defined the target group boundaries between the AGCH and other care models, allowing us to refine the AGCH admission criteria. Our findings may help to determine the required competencies of the interdisciplinary AGCH team and to develop triage instruments. The identified consideration themes can be used as conceptual framework in further research. The findings may also be of interests for healthcare systems outside the Netherlands who aspire to design integrated care for older people closer to home., (© 2024. The Author(s).)

Objective: During the COVID-19 pandemic, some centers converted intermediate care units (IMCUs) to COVID-19 ICUs (IMCU/ICUs). In this study, we compared adherence to lung protective ventilation (LPV) and outcomes for patients with COVID-19-related acute respiratory distress syndrome (ARDS) treated in an IMCU/ICU versus preexisting medical ICUs (MICUs)., Design: Retrospective observational study using electronic medical record data., Setting: Two academic medical centers from March 2020 to September 2020 (period 1) and October 2020 to May 2021 (period 2), which capture the first two COVID-19 surges in this health system., Patients: Adults with COVID-19 receiving invasive mechanical ventilation who met ARDS oxygenation criteria (Pao2/Fio2 ≤ 300 mm Hg or Spo2/Fio2 ≤ 315)., Interventions: None., Measurements and Main Results: We defined LPV adherence as the percent of the first 48 hours of mechanical ventilation that met a restrictive definition of LPV of, tidal volume/predicted body weight (Vt/PBW) less than or equal to 6.5 mL/kg and plateau pressure (Pplat) less than or equal to 30 cm H2o. In an expanded definition, we added that if Pplat is greater than 30 cm H2o, Vt/PBW had to be less than 6.0 mL/kg. Using the restricted definition, period 1 adherence was lower among 133 IMCU/ICU versus 199 MICU patients (92% [95% CI, 50-100] vs. 100% [86-100], p = 0.05). Period 2 adherence was similar between groups (100% [75-100] vs. 95% CI [65-100], p = 0.68). A similar pattern was observed using the expanded definition. For the full study period, the adjusted hazard of death at 90 days was lower in IMCU/ICU versus MICU patients (hazard ratio [HR] 0.73 [95% CI, 0.55-0.99]), whereas ventilator liberation by day 28 was similar between groups (adjusted subdistribution HR 1.09 [95% CI, 0.85-1.39])., Conclusions: In patients with COVID-19 ARDS treated in an IMCU/ICU, LPV adherence was similar to, and observed survival better than those treated in preexisting MICUs. With adequate resources, protocols, and staffing, IMCUs provide an effective source of additional ICU capacity for patients with acute respiratory failure., Competing Interests: Dr. Brodie reports receiving research support from and consults for LivaNova.
