The future of critical care

The Future of Critical Care: Optimizing Technologies and a Learning Healthcare System to Potentiate a More Humanistic Approach to Critical Care

While technological innovations are the invariable crux of speculation about the future of critical care, they cannot replace the clinician at the bedside. This article summarizes the work of the Society of Critical Care Medicine–appointed multiprofessional task for the Future of Critical Care. The Task Force notes that critical care practice will be transformed by novel technologies, integration of artificial intelligence decision support algorithms, and advances in seamless data operationalization across diverse healthcare systems and geographic regions and within federated datasets. Yet, new technologies will be relevant and meaningful only if they improve the very human endeavor of caring for someone who is critically ill.

How do we identify the crashing traumatic brain injury patient - the intensivist's view

PURPOSE OF REVIEW

Over 40% of patients with severe traumatic brain injury (TBI) show clinically significant neurological worsening within the acute admission period. This review addresses the importance of identifying the crashing TBI patient, the difficulties appreciating clinical neurological deterioration in the comatose patient and how neuromonitoring may provide continuous real-time ancillary information to detect physiologic worsening.

RECENT FINDINGS

The latest editions of the Brain Trauma Foundation's Guidelines omitted management algorithms for adult patients with severe TBI. Subsequently, three consensus-based management algorithms were published using a Delphi method approach to provide a bridge between the evidence-based guidelines and integration of the individual treatment modalities at the bedside. These consensus statements highlight the serious situation of critical deterioration requiring emergent evaluation and guidance on sedation holds to obtain a neurological examination while balancing the potential risks of inducing a stress response.

SUMMARY

One of the central tenets of neurocritical care is to detect the brain in trouble. The first and most fundamental neurological monitoring tool is the clinical exam. Ancillary neuromonitoring data may provide early physiologic biomarkers to help anticipate, prevent or halt secondary brain injury processes. Future research should seek to understand how data integration and visualization technologies may reduce the cognitive workload to improve timely detection of neurological deterioration.

Fully automated life support: an implementation and feasibility pilot study in healthy pigs

Background

Automated systems are available in various application areas all over the world for the purpose of reducing workload and increasing safety. However, such support systems that would aid caregivers are still lacking in the medical sector. With respect to workload and safety, especially, the intensive care unit appears to be an important and challenging application field. Whereas many closed-loop subsystems for single applications already exist, no comprehensive system covering multiple therapeutic aspects and interactions is available yet. This paper describes a fully closed-loop intensive care therapy and presents a feasibility analysis performed in three healthy pigs over a period of 72 h each to demonstrate the technical and practical implementation of automated intensive care therapy.

Methods

The study was performed in three healthy, female German Landrace pigs under general anesthesia with endotracheal intubation. An arterial and a central venous line were implemented, and a suprapubic urinary catheter was inserted. Electrolytes, glucose levels, acid-base balance, and respiratory management were completely controlled by an automated fuzzy logic system based on individual targets. Fluid management by adaption of the respective infusion rates for the individual parameters was included.

Results

During the study, no manual modification of the device settings was allowed or required. Homoeostasis in all animals was kept stable during the entire observation period. All remote-controlled parameters were maintained within physiological ranges for most of the time (free arterial calcium 73%, glucose 98%, arterial base excess 89%, and etCO₂ 98%). Subsystem interaction was analyzed.

Conclusions

In the presented study, we demonstrate the feasibility of a fully closed-loop system, for which we collected high-resolution data on the interaction and response of the different subsystems. Further studies should use big data approaches to analyze and investigate the interactions between the subsystems in more detail.

Challenges encountered by critical care unit managers in the large intensive care units

BACKGROUND

Nurses in intensive care units (ICUs) are exposed regularly to huge demands interms of fulfilling the many roles that are placed upon them. Unit managers, in particular, are responsible for the efficient management of the units and have the responsibilities of planning, organising, leading and controlling the daily activities in order to facilitate the achievement of the unit objectives.

OBJECTIVES

The objective of this study was to explore and present the challenges encountered by ICU managers in the management of large ICUs.

METHOD

A qualitative, exploratory and descriptive study was conducted at five hospital ICUs in Gauteng province, South Africa. Data were collected through individual interviews from purposively-selected critical care unit managers, then analysed using the matic coding.

RESULTS

Five themes emerged from the data: challenges related to the layout and structure of the unit, human resources provision and staffing, provision of material resources, stressors in the unit and visitors in the ICU.

CONCLUSION

Unit managers in large ICUs face multifaceted challenges which include the demand for efficient and sufficient specialised nurses; lack of or inadequate equipment that goes along with technology in ICU and supplies; and stressors in the ICU that limit the efficiency to plan, organise, lead and control the daily activities in the unit. The challenges identified call for multiple strategies to assist in the efficient management of large ICUs.

Voices of family members and significant others in the tele-intensive care unit

BACKGROUND

Research suggests that tele-intensive care units (tele-ICUs) are associated with decreases in mortality rates, length of stay, and health care costs. However, little is known about the awareness and perceptions of the tele-ICU among patients' significant others.

OBJECTIVES

To assess whether patients' significant others were informed about the tele-ICU, what their preferences are regarding source and type of information about the tele-ICU, and what their perceptions are of the impact of the tele-ICU on patient care.

METHODS

A survey was conducted with a nonprobability, convenience sample of patients' significant others at 3 health systems.

RESULTS

Two-thirds of patients' significant others reported that they were uninformed about the tele-ICU and identified staff as the preferred source for this information. The 3 most important topics of information were patients' physical privacy, impact on patient care, and the technology. Most expressed favorable perceptions of the tele-ICU.

CONCLUSIONS

This pilot study demonstrated significant gaps in communication about the tele-ICU between staff and patients' significant others and revealed a preference to be informed about the tele-ICU by staff. Study findings will help define goals, objectives, and methods for further research to improve communication with patients' significant others about the tele-ICU.

Team working in intensive care: current evidence and future endeavors

PURPOSE OF REVIEW

It has recently been argued that the future of intensive care medicine will rely on high quality management and teamwork. Therefore, this review takes an organizational psychology perspective to examine the most recent research on the relationship between teamwork, care processes, and patient outcomes in intensive care.

RECENT FINDINGS

Interdisciplinary communication within a team is crucial for the development of negotiated shared treatment goals and short-team patient outcomes. Interventions for maximizing team communication have received substantial interest in recent literature. Intensive care coordination is not a linear process, and intensive care teams often fail to discuss how to implement goals, trigger and align activities, or reflect on their performance. Despite a move toward interdisciplinary team working, clinical decision-making is still problematic and continues to be perceived as a top-down and authoritative process. The topic of team leadership in intensive care is underexplored and requires further research.

SUMMARY

Based on findings from the most recent research evidence in medicine and management, four principles are identified for improving the effectiveness of team working in intensive care: engender professional efficacy, create stable teams and leaders, develop trust and participative safety, and enable frequent team reflexivity.

Monitoring costs in the ICU: a search for a pertinent methodology

Attempts to determine costs in the intensive care unit (ICU) were not successful until now, as they failed to detect differences of costs between patients. The methodology and/or the instruments used might be at the origin of this failure. Based on the results of the European ICUs studies and on the descriptions of the activities of care in the ICU, we gathered and analysed the relevant literature concerning the monitoring of costs in the ICU. The aim was to formulate a methodology, from an economic perspective, in which future research may be framed. A bottom-up microcosting methodology will enable to distinguish costs between patients. The resulting information will at the same time support the decision-making of top management and be ready to include in the financial system of the hospital. Nursing staff explains about 30% of the total costs. This relation remains constant irrespective of the annual nurse/patient ratio. In contrast with other scoring instruments, the nursing activities score (NAS) covers all nursing activities. (1) NAS is to be chosen for quantifying nursing activities; (2) an instrument for measuring the physician's activities is not yet available; (3) because the nursing activities have a large impact on total costs, the standardisation of the processes of care (following the system approach) will contribute to manage costs, making also reproducible the issue of quality of care; (4) the quantification of the nursing activities may be the required (proxy) input for the automated bottom-up monitoring of costs in the ICU.

Measuring tele-ICU impact: does it optimize quality outcomes for the critically ill patient?

AIMS

To determine the relationship between tele-ICU (intensive care unit) implementations and improvement in quality measures and patient outcomes.

BACKGROUND

Tele-ICUs were designed to leverage scarce critical-care experts and promised to improve patient quality.

EVALUATION

Abstracts and peer-reviewed articles were reviewed to identify the associations between tele-ICU programmes and clinical outcomes, cost savings, and customer satisfaction.

KEY ISSUES

Few peer-reviewed studies are available and many variables in each study limit the ability to associate study conclusions to the overall tele-ICU programme. Further research is required to explore the impact of the tele-ICU on patient/family satisfaction. Research findings are highly dependent upon the level of ICU acceptance.

CONCLUSIONS

The tele-ICU, in collaboration with the ICU team, can be a valuable tool for the enhancement of quality goals although the ability to demonstrate cost savings is extremely complex. Studies clearly indicate that tele-ICU nursing vigilance can enhance patient safety by preventing potential patient harm.

IMPLICATIONS FOR NURSING MANAGEMENT

Nursing managers and leaders play a vital part in optimizing the quality role of the tele-ICU through supportive modelling and the maximization of ICU integration.

Rationing in the intensive care unit: to disclose or disguise?

INTRODUCTION

Growing pressures to ration intensive care unit beds and services pose novel challenges to clinicians. Whereas the question of how to allocate scarce intensive care unit resources has received much attention, the question of whether to disclose these decisions to patients and surrogates has not been explored.

KEY CONSIDERATIONS

We explore how considerations of professionalism, dual agency, patients' and surrogates' preferences, beneficence, and healthcare efficiency and efficacy influence the propriety of disclosing rationing decisions in the intensive care unit.

CONCLUSIONS

There are compelling conceptual reasons to support a policy of routine disclosure. Systematic disclosure of prevailing intensive care unit norms for making allocation decisions, and of at least the most consequential specific decisions, can promote transparent, professional, and effective healthcare delivery. However, many empiric questions about how best to structure and implement disclosure processes remain to be answered. Specifically, research is needed to determine how best to operationalize disclosure processes so as to maximize prospective benefits to patients and surrogates and minimize burdens on clinicians and intensive care units.

Rule of rescue or the good of the many? An analysis of physicians' and nurses' preferences for allocating ICU beds

PURPOSE

To examine intensive care unit (ICU) clinicians' willingness to trade off societal benefits in favor of a small chance of rescuing an identifiable critically ill patient.

METHODS

We sent mixed-methods questionnaires to national samples of US ICU clinicians, soliciting their preferences for allocating their last bed to a gravely ill patient with little chance to survive, versus a deceased or dying patient for whom aggressive management could help others through organ donation.

RESULTS

Complete responses were obtained from 684 of 2,206 physicians (31.0%) and 438 of 988 nurses (44.3%); there was no evidence of non-response bias. Physicians were more likely than nurses to adhere to the "rule of rescue" by allocating the last bed to the gravely ill patient (45.9 vs. 32.6%, difference = 13.2%; 95% CI 9.1-17.3%). The magnitude of the social benefit to be obtained through organ donor management (5 or 30 life-years added for transplant recipients) had small and inconsistent effects on clinicians' willingness to prioritize the donor. In qualitative analyses, the most common reason for allocating the last bed to an identifiable patient (identified by 65% of physicians and 75% of nurses) was that clinicians perceived strong obligations to identifiable living patients.

CONCLUSIONS

More than one-third of ICU clinicians forewent substantial social benefits so as to devote resources to an individual patient unlikely to benefit from them. Such allegiance to the rule of rescue suggests challenges for efforts to reform ICU triage practices.

Surgical intensive care unit--the trauma surgery perspective

PURPOSE

This review addresses and summarizes the key issues and unique specific intensive care treatment of adult patients from the trauma surgery perspective.

MATERIALS AND METHODS

The cornerstones of successful surgical intensive care management are fluid resuscitation, transfusion protocol and extracorporeal organ replacement therapies. The injury-type specific complications and unique pathophysiologic regulatory mechanisms of the traumatized patients influencing the critical care treatment are discussed.

CONCLUSIONS

Furthermore, the fundamental knowledge of the injury severity, understanding of the trauma mechanism, surgical treatment strategies and specific techniques of surgical intensive care are pointed out as essentials for a successful intensive care therapy.
