<title>Background</title>
<p>Intensive care units (ICU) are central facilities of medical care in hospitals world-wide and pose a significant financial burden on the health care system.</p>
</sec>
<sec>
<title>Objectives</title>
<p>To provide guidance and recommendations for the requirements of (infra)structure, personal, and organization of intensive care units.</p>
</sec>
<sec>
<title>Design and setting</title>
<p>Development of recommendations based on a systematic literature search and a formal consensus process from a group of multidisciplinary and multiprofessional specialists from the German Interdisciplinary Association of Intensive Care and Emergency Medicine (DIVI). The grading of the recommendation follows the report from an American College of Chest Physicians Task Force.</p>
</sec>
<sec>
<title>Results</title>
<p>The recommendations cover the fields of a 3-staged level of intensive care units, a 3-staged level of care with respect to severity of illness, qualitative and quantitative requirements of physicians and nurses as well as staffing with physiotherapists, pharmacists, psychologists, palliative medicine and other specialists, all adapted to the 3 levels of ICUs. Furthermore, proposals concerning the equipment and the construction of ICUs are supplied.</p>
</sec>
<sec>
<title>Conclusion</title>
<p>This document provides a detailed framework for organizing and planning the operation and construction/renovation of ICUs.</p>

<title>Introduction</title>
<p>The first recommendations of the German Interdisciplinary Association of Intensive Care and Emergency Medicine (DIVI) from 2010 (<xref ref-type="bibr" rid="ref1">1</xref>) and the &#x201C;Recommendations on basic requirements for intensive care units: structural and organizational aspects&#x201D; published by the European Society of Intensive Care Medicine (ESICM) in 2011 (<xref ref-type="bibr" rid="ref2">2</xref>) have exerted their influence over more than 10&#x2009;years. Since that time the general framework in the public health sector, the economic conditions and medical advancements have significantly changed. Furthermore, various intensive care societies around the world have offered recommendations on their websites. It was the aim of the DIVI to provide a comprehensive and updated guidance and recommendations for the requirements of (infra) structure, personal, and organization of intensive care units. The following manuscript gives an overview over most of the key recommendations. An extensive presentation of the complete text including background information, rationales, references as well as methodology and definitions is provided on the DIVI&#x2019;s homepage (<xref ref-type="bibr" rid="ref3">3</xref>).</p>
</sec>
<sec id="sec7" sec-type="methods">
<title>Methods</title>
<p>A systematic literature search was performed in PubMed and Epistemonikos in May 2021 (search terms see <xref ref-type="supplementary-material" rid="SM1">Supplementary material 1</xref>) which identified 2,701 potential publications. Of these, 243 manuscripts were considered relevant und were studied in full text. In addition, relevant publications from their reference lists, recommendations of major intensive care societies and other related documents or webpages were used. The listing of all references used, ordered by recommendation, is presented in <xref ref-type="supplementary-material" rid="SM2">Supplementary material 2</xref>. The grade of recommendation was determined using the guidelines as suggested by Guyatt et al. (<xref ref-type="bibr" rid="ref4">4</xref>). A core group (CW, RR, AM, FH, vdH.T), together with the participating sections of the DIVI, suggested a first version of the recommendations (14 video conferences). During a 2-day conference the team of authors completed the recommendations and the whole manuscript was finalized on November 2, 2022.</p>

These intensive care units are able to stabilize patients with disturbed vital signs and treat them temporarily in such a way that the patients can be transferred to an intensive care unit of a higher level within a framework of cooperation agreements or at least written agreements between the partners.</p></list-item><list-item><p><italic>Advanced intensive care</italic> (level 2): Level 2 ICUs are equipped to provide complete care for most conservative and surgical ICU patients. Patients for whom necessary medical specialities are not provided (e.g., neurosurgery, cardiac surgery, organ transplant medicine) or who require special types of organ replacement procedures (e.g., ECMO/ECLS) ought to be transferred to level 3 intensive care units within the framework of cooperative agreements.</p></list-item><list-item><p><italic>Comprehensive intensive care</italic> (level 3): Level 3 hospitals offer the complete spectrum of intensive care and medical specialities, possibly distributed over various specialized intensive care units. They are adequately staffed and equipped for the care of highly complex patients. Usually, these are university hospitals or large academic teaching hospitals.</p></list-item>

<p>&#x002A; An <italic>intensivist</italic> is a board-certified specialist in anesthesiology, internal medicine, neurology/neurosurgery or surgery with an additional specialized two-year training in intensive care (Germany).

<title>Discussion</title>
<p>These recommendations are based on an up-to-date systematic literature search endorsed by a group of experts in intensive care that represent the German Interdisciplinary Association of Intensive Care and Emergency Medicine (DIVI). They cover a wide range of topics such as staffing with physicians, nurses, and therapists as well as with further specialists, e.g., pharmacists, experts in clinical microbiology, psychologists, experts in nutrition, palliative care, and many others. Recommendations, both on quality and quantity, of personal are given and adapted to the different levels of intensive care units in detail.</p>
<p>A potential limitation may be the German perspective. However, intensive care in high-income countries appears to be on a similar level world-wide. Furthermore, the recommendations are not only based on the international literature but also account for existing guidelines and recommendations from many countries with highly developed intensive care medicine. Although the quantity of sound scientific data with respect to organizational aspects of intensive care is constantly rising, there remain many unresolved questions or controversial findings. Therefore, many recommendations, albeit strong, are based much on expert opinion, experience, and common medical knowledge with only little scientific data substantiating them. Future findings may alter some of them.</p>

<title>Conclusion</title>
<p>This document provides a detailed framework for organizing and planning the operation and construction/renovation of ICUs. A 3-staged level of intensive care units with respect to staffing and equipment, and a 3-staged level of care with respect to the severity of illness are recommended. The recommendations for personal and infrastructure are adapted to the 3 levels of intensive care units.</p>
