Defining Intensivists: A Retrospective Analysis of the Published Studies in the United States, 2010-2020.

OBJECTIVES: The Society of Critical Care Medicine last published an intensivist definition in 1992. Subsequently, there have been many publications relating to intensivists. Our purpose is to assess how contemporary studies define intensivist physicians. DESIGN: Systematic search of PubMed, Embase, and Web of Science (2010-2020) for publication titles with the terms intensivist, and critical care or intensive care physician, specialist, or consultant. We included studies focusing on adult U.S. intensivists and excluded non-data-driven reports, non-U.S. publications, and pediatric or neonatal ICU reports. We aggregated the study title intensivist nomenclatures and parsed Introduction and Method sections to discern the text used to define intensivists. Fourteen parameters were found and grouped into five definitional categories: A) No definition, B) Background training and certification, C) Works in ICU, D) Staffing, and E) Database related. Each study was re-evaluated against these parameters and grouped into three definitional classes (single, multiple, or no definition). The prevalence of each parameter is compared between groups using Fisher exact test. SETTING: U.S. adult ICUs and databases. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 657 studies, 105 (16%) met inclusion criteria. Within the study titles, 17 phrases were used to describe an intensivist; these were categorized as intensivist in 61 titles (58%), specialty intensivist in 30 titles (29%), and ICU/critical care physician in 14 titles (13%). Thirty-one studies (30%) used a single parameter (B-E) as their definition, 63 studies (60%) used more than one parameter (B-E) as their definition, and 11 studies (10%) had no definition (A). The most common parameter "Works in ICU" (C) in 52 studies (50%) was more likely to be used in conjunction with other parameters rather than as a standalone parameter (multiple parameters vs single-parameter studies; 73% vs 17%; p < 0.0001). CONCLUSIONS: There was no consistency of intensivist nomenclature or definitions in contemporary adult intensivist studies in the United States.

Flow-Sizing Critical Care Resources.

OBJECTIVES: To describe the factors affecting critical care capacity and how critical care organizations (CCOs) within academic centers in the U.S. flow-size critical care resources under normal operations, strain, and surge conditions. DATA SOURCES: PubMed, federal agency and American Hospital Association reports, and previous CCO survey results were reviewed. STUDY SELECTION: Studies and reports of critical care bed capacity and utilization within CCOs and in the United States were selected. DATA EXTRACTION: The Academic Leaders in the Critical Care Medicine Task Force established regular conference calls to reach a consensus on the approach of CCOs to "flow-sizing" critical care services. DATA SYNTHESIS: The approach of CCOs to "flow-sizing" critical care is outlined. The vertical (relation to institutional resources, e.g., space allocation, equipment, personnel redistribution) and horizontal (interdepartmental, e.g., emergency department, operating room, inpatient floors) integration of critical care delivery (ICUs, rapid response) for healthcare organizations and the methods by which CCOs flow-size critical care during normal operations, strain, and surge conditions are described. The advantages, barriers, and recommendations for the rapid and efficient scaling of critical care operations via a CCO structure are explained. Comprehensive guidance and resources for the development of "flow-sizing" capability by a CCO within a healthcare organization are provided. CONCLUSIONS: We identified and summarized the fundamental principles affecting critical care capacity. The taskforce highlighted the advantages of the CCO governance model to achieve rapid and cost-effective "flow-sizing" of critical care services and provide recommendations and resources to facilitate this capability. The relevance of a comprehensive approach to "flow-sizing" has become particularly relevant in the wake of the latest COVID-19 pandemic. In light of the growing risks of another extreme epidemic, planning for adequate capacity to confront the next critical care crisis is urgent.

A Rapid Response Team (RRT) System at a Cancer Center: Innovative Approaches to System Organization and Clinical RRT Pathways.

The Rapid Response Team (RRT) system at Memorial Sloan Kettering Cancer Center led by critical care medicine (CCM) advanced practice providers (APPs) expanded exponentially between 2009 and 2021. CCM-APPs are trained for care of critically ill patients as well as to oversee rapid response calls. The RRT is composed of a CCM-based RRT-APP, respiratory therapist, RRT-RN, and nursing supervisor. Since program inception, 11 RRT pathways and interventions have been developed and adjusted to improve multidisciplinary patient management. Pathways vary in complexity and require multidisciplinary collaboration. In some circumstances, the RRT patient may require transfer to outside facilities for services not provided at our oncology-based facility. RRT data are tracked across the hospital continuum with on-line reporting through RRT website dashboards. 2021 RRT data on electronic sepsis alerts, behavioral RRT and stroke alerts are presented. The RRT program is monitored through robust quality assurance. The APP-led RRT system's scope of care has been continuously expanded through the creation of RRT pathways to meet the increasingly complex medical needs of our patients.

Novel Technology Deployed for Remote Ventilator Management by Respiratory Therapists During the COVID-19 Pandemic: Lessons Learned.

A novel remote ventilator management (control) technology (Omnitool) was implemented for use with ICU patients during the COVID-19 pandemic to mitigate in-person respiratory therapist interactions and preserve personal protective equipment. In the latter half of 2020, eight mechanical ventilators were purchased and enabled for Omnitool deployment through the application of a vendor software option. Subsequently, these ventilators were outfitted with commercially available informatics hardware that permitted remote communication and management via the existing hospital network. In total, 17 patients with COVID-19 respiratory failure were placed on Omnitool enabled ventilators between January 1, 2021-April 30, 2021. The median Omnitool use days was 10. Deployment of a novel remote ventilator management technology is feasible; however, further study is needed to simplify the set up and utilization of the system. Future demands for remote ventilator management are predictable, whether in rural areas, military scenarios without adequate RT staffing, or in circumstances with new and easily transmissible toxic infections, and will continue to encourage the development of relatively easy to apply informatics-based solutions. Herein we share five lessons learned from our Omnitool deployment.

Analysis of Intent and Reason for Oncologic Therapy Administration in Cancer Patients Admitted to the Intensive Care Unit.

PURPOSE: To investigate the intent of, and reason for, administration of oncologic therapies in the intensive care unit (ICU). METHODS: Single center, retrospective, cohort study of patients with cancer who received oncologic therapies at a tertiary cancer center ICU between April 1, 2019 and March 31, 2020. Oncologic therapies included traditional cytotoxic chemotherapy, targeted therapy, immunotherapy, hormonal or biologic therapy directed at a malignancy and were characterized as initiation (initial administration) or continuation (part of an ongoing regimen). RESULTS: 84 unique patients (6.8% of total ICU admissions) received oncologic therapies in the ICU; 43 (51%) had hematologic malignancies and 41 (49%) had solid tumors. The intent of oncologic therapy was palliative in 63% and curative in 27%. Twenty-two (26%) patients received initiation and 62 (74%) received continuation oncologic therapies. The intent of oncologic therapy was significantly different by regimen type (initiation vs. continuation, p = <0.0001). Initiation therapy was more commonly prescribed with curative intent and continuation therapy was more commonly administered with palliative intent (p = <0.0001). Oncologic therapies were given in the ICU mainly for an oncologic emergency (56%) and because the patients happened to be in the ICU for a non-oncologic critical illness when their oncologic therapy was due (34.5%). CONCLUSION: Our study provides intensivists with a better understanding of the context and intent of oncologic therapies and why these therapies are administered in the ICU.

Intracardiac Thrombus in Transit Detected by Point-of-Care Ultrasound.

Pulmonary embolism (PE) is a condition with a high rate of morbidity and mortality if it is not recognized and treated in a timely fashion. Point-of-care ultrasound (POCUS) is a useful tool that can help clinicians make prompt diagnosis. We present a case where we diagnosed massive PE through visualizing an intracardiac thrombus in transit, and we highlight some important ultrasonographic features.

A Tale of Two Pulmonary Artery Catheters.

Innovative catheter-based therapies are increasingly being used for the treatment of patients with submassive pulmonary embolism. These patients may be monitored in the intensive care unit following insertion of specialized pulmonary artery catheters. However, the infusion catheters utilized in catheter-based therapies differ greatly from traditional pulmonary artery catheters designed for hemodynamic monitoring. As such, the critical care team will have to be familiar with the monitoring and management of these novel catheters. Important distinctions between the catheters are illustrated using a clinical case report.

A pilot survey of ventilated cancer patients' perspectives and recollections of early mobility in the intensive care unit.

PURPOSE: To determine the level of recall, satisfaction, and perceived benefits of early mobility (EM) among ventilated cancer patients after extubation in the intensive care unit (ICU). METHODS: A survey of patients' perceptions and recollections of EM was administered within 72 h of extubation. Data on recall of EM participation, activities achieved, adequacy of staffing and rest periods, strength to participate, activity level of difficulty, satisfaction with staff instructions, breathing management, and overall rating of the experience were analyzed. The Confusion Assessment Method for ICU (CAM-ICU) was used for delirium screening. RESULTS: Fifty-four patients comprised the study group. Nearly 90% reported satisfaction with instructions, staffing, rest periods, and breathing management during EM. Participants indicated that EM maintained their strength (67%) and gave them control over their recovery (61%); a minority felt optimistic (37%) and safe (22%). Patients who achieved more sessions and "out-of-bed" exercises had better recall of actual activities compared with those who exercised in bed. Overall, patients with CAM-ICU-positive results (33%) performed less physical and occupational therapy exercises. CONCLUSIONS: Ventilated cancer patients reported an overall positive EM experience, but factual memory impairment of EM activities was common. These findings highlight the needs and the importance of shaping strategies to deliver a more patient focused EM experience.

Characteristics and outcomes of patients with solid tumors receiving chemotherapy in the intensive care unit.

PURPOSE: The objective of this study was to evaluate the short- and long-term outcomes of adult patients with solid tumors receiving chemotherapy in the intensive care unit (ICU). METHODS: This was a retrospective single-center study comparing the outcomes of patients with solid tumors who received chemotherapy in the ICU with a matched cohort of ICU patients (by age, sex, and tumor type) who did not receive chemotherapy. Conditional logistic regression and shared frailty Cox regression were used to assess short-term (ICU and hospital) mortality and death by 12-month post-hospital discharge, respectively. RESULTS: Seventy-three patients with solid tumors who received chemotherapy in the ICU were successfully matched. The most common solid tumors included thoracic (30%), genitourinary (26%), and breast (16%). The ICU, hospital, and 12-month (post discharge)  mortality rates of patients who recieved chomtherapy in the ICU were 23%, 36%, and 43%, respectively. When compared to the matched cohort of patients who did not receive chemotherapy, patients who received chemotherapy had a significantly longer length of stay in the ICU (median 7 vs. 4 days, p < 0.001) and hospital (median 15 vs. 11 days, p = 0.011) but similar short-term ICU and hospital mortality rates (23% vs. 18% and 36% vs. 38%, respectively). Patients who received chemotherapy in the ICU were at a lower risk of death by 12 months (HR 0.31, p < 0.001) compared to the matched cohort on multivariable analysis. CONCLUSIONS: Patients with solid tumors who received chemotherapy had increased ICU and hospital length of stay compared to patients who did not. Although short-term mortality did not differ, patients who received chemotherapy in the ICU had improved long-term survival. Our data can inform critical care triage decisions to include patients who are to receive chemotherapy in the ICU.

Intensivists in U.S. Acute Care Hospitals.

OBJECTIVES: To determine the total numbers of privileged and full-time equivalent intensivists in acute care hospitals with intensivists and compare the characteristics of hospitals with and without intensivists. DESIGN: Retrospective analysis of the American Hospital Association Annual Survey Database (Fiscal Year 2015). SETTING: Two-thousand eight-hundred fourteen acute care hospitals with ICU beds. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 2,814 acute care hospitals studied, 1,469 (52%) had intensivists and 1,345 (48%) had no intensivists. There were 28,808 privileged and 19,996 full-time equivalent intensivists in the 1,469 hospitals with intensivists. In these hospitals, the median (25-75th percentile) numbers of privileged and full-time equivalent intensivists were 11 (5-24) and 7 (2-17), respectively. Compared with hospitals without intensivists, hospitals with privileged intensivists were primarily located in metropolitan areas (91% vs 50%; p < 0.001) and at the aggregate level had nearly thrice the number of hospital beds (403,522 [75%] vs 137,146 [25%]), 3.6 times the number of ICU beds (74,222 [78%] vs 20,615 [22%]), and almost twice as many ICUs (3,383 [65%] vs 1,846 [35%]). At the hospital level, hospitals with privileged intensivists had significantly more hospital beds (median, 213 vs 68; p < 0.0001), ICU beds (median, 32 vs 8; p < 0.0001), a higher ratio of ICU to hospital beds (15.6% vs 12.6%; p < 0.0001), and a higher number of ICUs per hospital (2 vs 1; p < 0.0001) than hospitals without intensivists. CONCLUSIONS: Analyzing the intensivist section of the American Hospital Association Annual Survey database is a novel approach to estimating the numbers of privileged and full-time equivalent intensivists in acute care hospitals with ICU beds in the United States. This methodology opens the door to an enhanced understanding of the current supply and distribution of intensivists as well as future research into the intensivist workforce.

Characteristics and outcomes of patients with hematologic malignancies receiving chemotherapy in the intensive care unit.

BACKGROUND: The objective of this study was to evaluate the short-term and long-term outcomes of adult patients with hematologic malignancies who received chemotherapy in the intensive care unit (ICU). METHODS: This was a retrospective, single-center study comparing the outcomes of patients with hematologic malignancies who received chemotherapy in the ICU with a matched cohort of ICU patients who did not receive chemotherapy. Conditional logistic regression and shared-frailty Cox regression were used to assess short-term (ICU and hospital) mortality and death by 12 months after hospital discharge, respectively. RESULTS: One hundred eighty-one patients with hematologic malignancies received chemotherapy in the ICU. The ICU and hospital mortality rates were 25% and 42% for chemotherapy patients and 22% and 33% for non-chemotherapy patients, respectively. Higher severity of illness scores on ICU admission were significantly associated with higher ICU mortality (odds ratio, 1.07; P < .001) and hospital mortality (odds ratio, 1.05; P ≤ .001). Six-month and 12-month survival estimates posthospital discharge were 58% and 50%, respectively. Compared with the matched cohort of patients who did not receive chemotherapy, those who did receive chemotherapy had a significantly longer length of stay in the ICU (median, 6 vs 3 days; P < .001) and in the hospital (median, 22 vs 14 days; P = .024). In multivariable analysis, the patients who received chemotherapy in the ICU had a trend toward a higher risk of dying by 12 months (hazard ratio, 1.45; P = .08). CONCLUSIONS: Short-term mortality was similar among patients with hematologic malignancies who did and did not receive chemotherapy in the ICU, although patients who received chemotherapy had increased resource utilization. These results may inform ICU triage and goals-of-care discussions with patients and their families regarding outcomes after receiving chemotherapy in the ICU.

Informatics for the Modern Intensive Care Unit.

Advanced informatics systems can help improve health care delivery and the environment of care for critically ill patients. However, identifying, testing, and deploying advanced informatics systems can be quite challenging. These processes often require involvement from a collaborative group of health care professionals of varied disciplines with knowledge of the complexities related to designing the modern and "smart" intensive care unit (ICU). In this article, we explore the connectivity environment within the ICU, middleware technologies to address a host of patient care initiatives, and the core informatics concepts necessary for both the design and implementation of advanced informatics systems.

Trends in Critical Care Beds and Use Among Population Groups and Medicare and Medicaid Beneficiaries in the United States: 2000-2010.

OBJECTIVES: To analyze patterns of critical care medicine beds, use, and costs in acute care hospitals in the United States and relate critical care medicine beds and use to population shifts, age groups, and Medicare and Medicaid beneficiaries from 2000 to 2010. DESIGN: Retrospective study of data from the federal Healthcare Cost Report Information System, American Hospital Association, and U.S. Census Bureau. SUBJECTS: None. INTERVENTIONS: None. SETTING: Acute care U.S. hospitals with critical care medicine beds. MEASUREMENTS AND MAIN RESULTS: From 2000 to 2010, U.S. hospitals with critical care medicine beds decreased by 17% (3,586-2,977), whereas the U.S. population increased by 9.6% (282.2-309.3M). Although hospital beds decreased by 2.2% (655,785-641,395), critical care medicine beds increased by 17.8% (88,235-103,900), a 20.4% increase in the critical care medicine-to-hospital bed ratio (13.5-16.2%). There was a greater percentage increase in premature/neonatal (29%; 14,391-18,567) than in adult (15.9%; 71,978-83,417) or pediatric (2.7%; 1,866-1,916) critical care medicine beds. Hospital occupancy rates increased by 10.4% (58.6-64.6%), whereas critical care medicine occupancy rates were stable (range, 65-68%). Critical care medicine beds per 100,000 total population increased by 7.4% (31.3-33.6). The proportional use of critical care medicine services by Medicare beneficiaries decreased by 17.3% (37.9-31.4%), whereas that by Medicaid rose by 18.3% (14.5-17.2%). Between 2000 and 2010, annual critical care medicine costs nearly doubled (92.2%; $56-108 billion). In the same period, the proportion of critical care medicine cost to the gross domestic product increased by 32.1% (0.54-0.72%). CONCLUSIONS: Critical care medicine beds, use, and costs in the United States continue to rise. The increasing use of critical care medicine by the premature/neonatal and Medicaid populations should be considered by healthcare policy makers, state agencies, and hospitals as they wrestle with critical care bed growth and the associated costs.

Critical Care Medicine Beds, Use, Occupancy, and Costs in the United States: A Methodological Review.

This article is a methodological review to help the intensivist gain insights into the classic and sometimes arcane maze of national databases and methodologies used to determine and analyze the ICU bed supply, use, occupancy, and costs in the United States. Data for total ICU beds, use, and occupancy can be derived from two large national healthcare databases: the Healthcare Cost Report Information System maintained by the federal Centers for Medicare and Medicaid Services and the proprietary Hospital Statistics of the American Hospital Association. Two costing methodologies can be used to calculate U.S. ICU costs: the Russell equation and national projections. Both methods are based on cost and use data from the national hospital datasets or from defined groups of hospitals or patients. At the national level, an understanding of U.S. ICU bed supply, use, occupancy, and costs helps provide clarity to the width and scope of the critical care medicine enterprise within the U.S. healthcare system. This review will also help the intensivist better understand published studies on administrative topics related to critical care medicine and be better prepared to participate in their own local hospital organizations or regional critical care medicine programs.

Critical Care Organizations in Academic Medical Centers in North America: A Descriptive Report.

OBJECTIVES: With the exception of a few single-center descriptive reports, data on critical care organizations are relatively sparse. The objectives of our study were to determine the structure, governance, and experience to date of established critical care organizations in North American academic medical centers. DESIGN: A 46-item survey questionnaire was electronically distributed using Survey Monkey to the leadership of 27 identified critical care organizations in the United States and Canada between September 2014 and February 2015. A critical care organization had to be headed by a physician and have primary governance over the majority, if not all, of the ICUs in the medical center. MEASUREMENTS AND MAIN RESULTS: We received 24 responses (89%). The majority of the critical care organizations (83%) were called departments, centers, systems, or operations committees. Approximately two thirds of respondents were from larger (> 500 beds) urban institutions, and nearly 80% were primary university medical centers. On average, there were six ICUs per academic medical center with a mean of four ICUs under critical care organization governance. In these ICUs, intensivists were present in-house 24/7 in 49%; advanced practice providers in 63%; hospitalists in 21%; and telemedicine coverage in 14%. Nearly 60% of respondents indicated that they had a separate hospital budget to support data management and reporting, oversight of their ICUs, and rapid response teams. The transition from the traditional model of ICUs within departmentally controlled services or divisions to a critical care organization was described as gradual in 50% and complete in only 25%. Nearly 90% indicated that their critical care organization governance structure was either moderately or highly effective; a similar number suggested that their critical care organizations were evolving with increasing domain and financial control of the ICUs at their respective institutions. CONCLUSIONS: Our survey of the very few critical care organizations in North American academic medical centers showed that the governance models of critical care organizations vary and continue to evolve. Additional studies are warranted to improve our understanding of the factors that can foster the growth of critical care organizations and how they can be effective.

Characteristics and Outcomes of Ethics Consultations in an Oncologic Intensive Care Unit.

OBJECTIVE: To evaluate the frequency, characteristics, and outcomes of ethics consultations in critically ill patients with cancer. DESIGN, SETTING, AND METHODS: This is a retrospective analysis of all adult patients with cancer who were admitted to the intensive care unit (ICU) of a comprehensive cancer center and had an ethics consultation between September 2007 and December 2011. Demographic and clinical variables were abstracted along with the details and contexts of the ethics consultations. MAIN RESULTS: Ethics consultations were obtained on 53 patients (representing 1% of all ICU admissions). The majority (90%) of patients had advanced-stage malignancies, had received oncologic therapies within the past 12 months, and required mechanical ventilation and/or vasopressor therapy for respiratory failure and/or severe sepsis. Two-thirds of the patients lacked decision-making capacity and nearly all had surrogates. The most common reasons for ethics consultations were disagreements between the patients/surrogates and the ICU team regarding end-of-life care. After ethics consultations, the surrogates agreed with the recommendations made by the ICU team on the goals of care in 85% of patients. Moreover, ethics consultations facilitated the provision of palliative medicine and chaplaincy services to several patients who did not have these services offered to them prior to the ethics consultations. CONCLUSION: Our study showed that ethics consultations were helpful in resolving seemingly irreconcilable differences between the ICU team and the patients' surrogates in the majority of cases. Additionally, these consultations identified the need for an increased provision of palliative care and chaplaincy visits for patients and their surrogates at the end of life.

A Case Series of Patients With Complex Airway Disease and Large Thyroid Tumors Anterior to the Trachea Precluding Tracheostomy.

BACKGROUND: This case series explores the management of respiratory failure in patients with large anterior tracheal thyroid tumors where tracheostomy is not an option. To our knowledge, this study is the first to address the challenges associated with caring for such patients. CASE SUMMARY: We present the clinical courses of four intubated adults with advanced thyroid cancer and complex airway issues that preclude surgical tracheostomy. Interventions included custom airway stents, long-term intubation, and oncological therapies. Ethical quandaries around patient autonomy and capacity emerged, exacerbated by the absence of viable exit strategies for prolonged intubation, notably the performance of a tracheostomy, causing emotional distress in patients, families, and staff. CONCLUSIONS: This study showcases the multifaceted challenges in medical, ethical, and emotional domains associated with managing intubated patients with complex disease precluding tracheotomies. We advocate for a nuanced, multidisciplinary, and personalized approach to confront unique issues in airway management, ethical considerations, and disposition.

EMPOWER: A Multi-Site Pilot Trial to Reduce Distress in Surrogate Decision-Makers in the ICU.

CONTEXT: Efforts to reduce the psychological distress of surrogate decision-makers of critically ill patients have had limited success, and some have even exacerbated distress. OBJECTIVES: The aim of this study was to determine the feasibility, acceptability, and preliminary efficacy of EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), an ultra-brief (∼2-hour), 6-module manualized psychological intervention for surrogates. METHODS: Surrogates who reported significant anxiety and/or an emotionally close relationship with the patient (n=60) were randomized to receive EMPOWER or enhanced usual care (EUC) at one of three metropolitan hospitals. Participants completed evaluations of EMPOWER's acceptability and measures of psychological distress pre-intervention, immediately post-intervention, and at 1- and 3-month follow-up assessments. RESULTS: Delivery of EMPOWER appeared feasible, with 89% of participants completing all 6 modules, and acceptable, with high ratings of satisfaction (mean=4.5/5, SD = .90). Compared to EUC, intent-to-treat analyses showed EMPOWER was superior at reducing peritraumatic distress (Cohen's d = -0.21, small effect) immediately post-intervention and grief intensity (d = -0.70, medium-large effect), posttraumatic stress (d = -0.74, medium-large effect), experiential avoidance (d = -0.46, medium effect), and depression (d = -0.34, small effect) 3 months post-intervention. Surrogate satisfaction with overall critical care (d = 0.27, small effect) was higher among surrogates randomized to EMPOWER. CONCLUSIONS: EMPOWER appeared feasible and acceptable, increased surrogates' satisfaction with critical care, and prevented escalation of posttraumatic stress, grief, and depression 3 months later.

Critical care medicine in the United States: addressing the intensivist shortage and image of the specialty.

Intensivists are increasingly needed to care for the critically ill and manage ICUs as ICU beds, utilization, acuity of illness, complexity of care and costs continue to rise. However, there is a nationwide shortage of intensivists that has occurred despite years of well publicized warnings of an impending workforce crisis from specialty societies and the federal government. The magnitude of the intensivist shortfall, however, is difficult to determine because there are many perspectives of optimal ICU administration, patient coverage and intensivist availability and a lack of national data on intensivist practices. Nevertheless, the intensivist shortfall is quite real as evidenced by the alternative solutions that hospitals are deploying to provide care for their critically ill patients. In the midst of these manpower struggles, the critical care environment is dynamically changing and becoming more stressful. Severe hospital bed availability and fiscal constraints are forcing ICUs to alter their approaches to triage, throughput and unit staffing. National and local organizations are mandating that hospitals comply with resource intensive and arguably unproven initiatives to monitor and improve patient safety and quality, and informatics systems. Lastly, there is an ongoing sense of professional dissatisfaction among intensivists and a lack of public awareness that critical care medicine is even a distinct specialty. This article offers proposals to increase the adult intensivist workforce through expansion and enhancements of internal medicine based critical care training programs, incentives for recent graduates to enter the critical care medicine field, suggestions for improvements in the critical care profession and workplace to encourage senior intensivists to remain in the field, proactive marketing of critical care, and expanded engagement by the critical care societies in the challenges facing intensivists.
