Trend of Decreased Length of Stay in the Intensive Care Unit (ICU) and in the Hospital with Palliative Care Integration into the ICU

Palliative and end-of-life care practices for critically ill patients and their families in a peri-intensive care setting: A protocol for an umbrella review

OBJECTIVES

This umbrella review will summarize palliative and end-of-life care practices in peri-intensive care settings by reviewing systematic reviews in intensive care unit (ICU) settings. Evidence suggests that integrating palliative care into ICU management, initiating conversations about care goals, and providing psychological and emotional support can significantly enhance patient and family outcomes.

METHODS

The Joanna Briggs Institute (JBI) methodology for umbrella reviews will be followed. The search will be carried out from inception until 30 September 2023 in the following databases: Cochrane Library, SCOPUS, Web of Science, CINAHL Complete, Medline, EMBASE, and PsycINFO. Two reviewers will independently conduct screening, data extraction, and quality assessment, and to resolve conflicts, adding a third reviewer will facilitate the consensus-building process. The quality assessment will be carried out using the JBI Critical Appraisal Checklist. The review findings will be reported per the guidelines outlined in the Preferred Reporting Items for Overviews of Reviews statement.

RESULTS

This umbrella review seeks to inform future research and practice in critical care medicine, helping to ensure that end-of-life care interventions are optimized to meet the needs of critically ill patients and their families.

Benefits of Early Utilization of Palliative Care Consultation in Trauma Patients

OBJECTIVES

To determine the effects of palliative care consultation if performed within 72 hours of admission on length of stay (LOS), mortality, and invasive procedures.

DESIGN

Retrospective observational study.

SETTING

Single-center level 1 trauma center.

PATIENTS

Trauma patients, admitted to ICU with palliative care consultation.

INTERVENTION

None.

MEASUREMENTS AND MAIN RESULTS

The ICU LOS was decreased in the early palliative care (EPC) group compared with the late palliative care (LPC) group, by 6 days versus 12 days, respectively. Similarly, the hospital LOS was also shorter in the EPC group by 8 days versus 17 days in the LPC group. In addition, the EPC group had lower rates of tracheostomy (4% vs 14%) and percutaneous gastrostomy tubes (4% vs 15%) compared with the LPC group. There was no difference in mortality or discharge disposition between patients in the EPC versus LPC groups. It is noteworthy that the patients who received EPC were slightly older, but there were no other significant differences in demographics.

CONCLUSIONS

EPC is associated with fewer procedures and a shorter amount of time spent in the hospital, with no immediate effect on mortality. These outcomes are consistent with studies that show patients' preferences toward the end of life, which typically involve less time in the hospital and fewer invasive procedures.

The impact of daylight and window views on length of stay among patients with heart disease: A retrospective study in a cardiac intensive care unit

Background

Heart disease is the leading cause of death in the United States. The length of stay (LOS) is a well-established parameter used to evaluate health outcomes among critically ill patients with heart disease in cardiac intensive care units (CICUs). While evidence suggests that the presence of daylight and window views can positively influence patients' LOS, no studies to date have differentiated the impact of daylight from window views on heart disease patients. Also, existing research studies on the impact of daylight and window views have failed to account for key clinical and demographic variables that can impact the benefit of such interventions in CICUs.

Methods

This retrospective study investigated the impact of access to daylight vs. window views on CICU patients' LOS. The study CICU is located in a hospital in the southeast United States and has rooms of the same size with different types of access to daylight and window views, including rooms with daylight and window views (with the patient bed located parallel to full-height, south-facing windows), rooms with daylight and no window views (with the patient bed located perpendicular to the windows), and windowless rooms. Data from electronic health records (EHRs) for the time-period September 2015 to September 2019 (n=2936) were analyzed to investigate the impact of room type on patients' CICU LOS. Linear regression models were developed for the outcome of interest, controlling for potential confounding variables.

Results

Ultimately, 2319 patients were finally included in the study analysis. Findings indicated that patients receiving mechanical ventilation in rooms with access to daylight and window views had shorter LOS durations (16.8 h) than those in windowless rooms. Sensitivity analysis for a subset of patients with LOS ≤3 days revealed that parallel bed placement to the windows and providing access to both daylight and window views significantly reduced their LOS compared to windowless rooms in the unit (P=0.007). Also, parallel bed placement to the window significantly reduced LOS in this patient subset for those with an experience of delirium (P=0.019), dementia (P=0.008), anxiety history (P=0.009), obesity (P=0.003), and those receiving palliative care (P=0.006) or mechanical ventilation (P=0.033).

Conclusions

Findings from this study could help architects make design decisions and determine optimal CICU room layouts. Identifying the patients who benefit most from direct access to daylight and window views may also help CICU stakeholders with patient assignments and hospital training programs.

Characteristics, ICU Interventions, and Clinical Outcomes of Patients With Palliative Care Triggers in a Mixed Community-Based Intensive Care Unit

Objective: Integration of palliative care initiatives in the intensive care unit (ICU) benefit patients and improve outcomes. Palliative care triggers (PCTs) is a screening tool that aides in stratifying patients who would benefit most from an early palliative care approach. There is no consensus on PCT selection or best timing for implementation. We evaluated the clinical characteristics, ICU and palliative care interventions, and clinical outcomes of critically ill patients with PCT in a community-based mixed ICU. Methods: This retrospective study was conducted in a 44-bed adult, mixed ICU in a 407-bed community-based teaching hospital in Florida. Eleven PCTs were used as a screening tool during multidisciplinary rounds (MDRs). Patients were analyzed based on presence or absence of PCT as well as having met high (>2) versus low (<2) PCT. Data collected included patient demographics, ICU resource utilization and clinical outcomes. We considered a two-sided P value of less than .05 to indicate statistical significance with a 95% confidence interval. Results: Of 388 ICU patients, 189 (48.7%) met at least 1 PCT and 199 (51.3%) did not. The trigger group had higher Acute Physiology and Chronic Evaluation (APACHE) and Sequential Organ Failure Assessment (SOFA) scores within 24 h of ICU admission. The most common PCTs identified were ICU length of stay greater than 7 days or readmission to ICU, terminal prognosis and assisting family in transitioning goals of care. There were statistically significant differences in ICU resource utilization, palliative care interventions, and overall worse clinical outcomes in the trigger-detected group. Similar findings were seen in the cohort with high PCT (>2). Conclusions: Our study supports the implementation of a tailored 11-item palliative care screening tool to effectively identify ICU patients with high ICU and palliative care interventions and worse clinical outcomes.

Stakeholder engagement as a strategy to enhance palliative care involvement in intensive care units: A theory of change approach

BACKGROUND

Adult patients admitted to intensive care units in the terminal phase experience high symptom burden, increased costs, and diminished quality of dying. There is limited literature on palliative care engagement in ICU, especially in lower-middle-income countries. This study explores a strategy to enhance palliative care engagement in ICU through a stakeholder participatory approach.

METHODS

Theory of Change approach was used to develop a hypothetical causal pathway for palliative care integration into ICUs in India. Four facilitated workshops and fifteen research team meetings were conducted virtually over three months. Thirteen stakeholders were purposively chosen, and three facilitators conducted the workshops. Data included workshop discussion transcripts, online chat box comments, and team meeting minutes. These were collected, analysed and represented as theory of change map.

RESULTS

The desired impact of palliative care integration was good death. Potential long-term outcomes identified were fewer deaths in ICUs, discharge against medical advice, and inappropriate admissions; increased referrals to palliative care; and improved patient and family satisfaction. Twelve preconditions were identified, and eleven key interventions were developed. Five overarching assumptions related to contextual factors influencing the outcomes of interventions.

CONCLUSION

Theory of change framework facilitated the identification of proposed mechanisms and interventions underpinning palliative care integration in ICUs.

Healthcare Professionals' Perspective on Palliative Care in Intensive Care Settings: An Interpretive Descriptive Study

There is a growing need to integrate palliative care into intensive care units and to develop appropriate knowledge translation strategies. However, multiple challenges persist in attempts to achieve this objective. In this study, we aimed to explore intensive care professionals' perspectives on providing palliative and end-of-life care within an intensive care context. We used an interpretive description approach and interviewed 36 intensive care professionals at four hospitals in Saudi Arabia. Our findings reflect a discourse about end-of-life care driven by a do-not-resuscitate classification and challenges associated with family involvement in care goals. We provide key insights of importance for the development of strategies for the integration and knowledge translation of palliative care into intensive care contexts.

Impact of Palliative Care on Interhospital Transfers to the Intensive Care Unit

Community hospitals will often transfer their most complex, critically ill patients to intensive care units (ICUs) of tertiary care centers for specialized, comprehensive care. This population of patients has high rates of morbidity and mortality. Palliative care involvement in critically ill patients has been demonstrated to reduce over-utilization of resources and hospital length of stays. We hypothesized that transfers from community hospitals had low rates of palliative care involvement and high utilization of ICU resources. In this single-center retrospective cohort study, 848 patients transferred from local community hospitals to the medical ICU (MICU) and cardiac care unit (CCU) at a tertiary care center between 2016-2018 were analyzed for patient disposition, length of stay, hospitalization cost, and time to palliative care consultation. Of the 848 patients, 484 (57.1%) expired, with 117 (13.8%) having expired within 48 hours of transfer. Palliative care consult was placed for 201 (23.7%) patients. Patients with palliative care consult were statistically more likely to be referred to hospice (p<0.001). Over two-thirds of palliative care consults were placed later than 5 days after transfer. Time to palliative care consult was positively correlated with length of hospitalization among MICU patients (r=0.79) and CCU patients (r=0.90). Time to palliative consult was also positively correlated with hospitalization cost among MICU patients (r=0.75) and CCU patients (r=0.86). These results indicate early palliative care consultation in this population may result in timely goals of care discussions and optimization of resources.

Palliative care interventions in intensive care unit patients

PURPOSE

The integration of palliative care into intensive care units (ICUs) is advocated to mitigate physical and psychological burdens for patients and their families, and to improve end-of-life care. The most efficacious palliative care interventions, the optimal model of their delivery and the most appropriate outcome measures in ICU are not clear.

METHODS

We conducted a systematic review of randomised clinical trials and observational studies to evaluate the number and types of palliative care interventions implemented within the ICU setting, to assess their impact on ICU practice and to evaluate differences in palliative care approaches across different countries.

RESULTS

Fifty-eight full articles were identified, including 9 randomised trials and 49 cohort studies; all but 4 were conducted within North America. Interventions were categorised into five themes: communication (14, 24.6%), ethics consultations (5, 8.8%), educational (18, 31.6%), involvement of a palliative care team (28, 49.1%) and advance care planning or goals-of-care discussions (7, 12.3%). Thirty studies (51.7%) proposed an integrative model, whilst 28 (48.3%) reported a consultative one. The most frequently reported outcomes were ICU or hospital length of stay (33/55, 60%), limitation of life-sustaining treatment decisions (22/55, 40%) and mortality (15/55, 27.2%). Quantitative assessment of pooled data was not performed due to heterogeneity in interventions and outcomes between studies.

CONCLUSION

Beneficial effects on the most common outcomes were associated with strategies to enhance palliative care involvement, either with an integrative or a consultative approach. Few studies reported functional outcomes for ICU patients. Almost all studies were from North America, limiting the generalisability to other healthcare systems.

Electronic medical orders for life-sustaining treatment in New York State: Length of stay, direct costs in an ICU setting

OBJECTIVE

In the United States, approximately 20% patients die annually during a hospitalization with an intensive care unit (ICU) stay. Each year, critical care costs exceed $82 billion, accounting for 13% of all inpatient hospital costs. Treatment of sepsis is listed as the most expensive condition in US hospitals, costing more than $20 billion annually. Electronic Medical Orders for Life-Sustaining Treatment (eMOLST) is a standardized documentation process used in New York State to convey patients' wishes regarding cardiopulmonary resuscitation and other life-sustaining treatments. No study to date has looked at the effect of eMOLST as an advance care planning tool on ICU and hospital costs using estimates of direct costs. The objective of our study was to investigate whether signing of eMOLST results in any reduction in length of stay and direct costs for a community-based hospital in New York State.

METHOD

A retrospective chart review was conducted between July 2016 and July 2017. Primary outcome measures included length of hospital stay, ICU length of stay, total direct costs, and ICU costs. Inclusion criteria were patients ≥65 years of age and admitted into the ICU with a diagnosis of sepsis. An independent samples t test was used to test for significant differences between those who had or had not completed the eMOLST form.

RESULT

There were no statistical differences for patients who completed or did not complete the eMOLST form on hospital's total direct cost, ICU cost, total length of hospital stay, and total hours spent in the ICU.

SIGNIFICANCE OF RESULTS

Completing an eMOLST form did not have any effect on reducing total direct cost, ICU cost, total length of hospital stay, and total hours spent in the ICU.

Impact of major illnesses and geographic regions on do-not-resuscitate rate and its potential cost savings in Taiwan

Background/Purpose

Do-not-resuscitate (DNR) is a legal order that demonstrates a patient’s will to avoid further suffering from advanced treatment at the end of life. The concept of palliative care is increasingly accepted, but the impacts of different major illnesses, geographic regions, and health expenses on DNR rates remain unclear.

Methods

This study utilized the two-million National Health Insurance (NHI) Research Database to examine the percentage of DNR rates among all deaths in hospitals from 2001 to 2011. DNR in the study was defined as no resuscitation before death in hospitals. Death records were extracted from the database and correlated with healthcare information. Descriptive statistics were compiled to examine the relationships between DNR rates and variables including major illnesses, geographic regions, and NHI spending.

Results

A total of 126,390 death records were extracted from the database for analysis. Among cancer-related deaths, pancreatic cancer patients had the highest DNR rate (86.99%) and esophageal cancer patients had the lowest DNR rate (71.62%). The higher DNR rate among cancer-only patients (79.53%) decreased with concomitant dialysis (66.07%) or ventilator use (57.85%). The lower DNR rates in patients with either chronic dialysis (51.27%) or ventilator use (59.10%) increased when patients experienced these two conditions concomitantly (61.31%). Although DNR rates have consistently increased over time across all regions of Taiwan, a persistent disparity was noted between the East and the South (76.89% vs. 70.78% in 2011, p < 0.01). After adjusting for potential confounders, DNR patients had significantly lower NHI spending one year prior to death ($67,553), compared with non-DNR patients.

Conclusion

Our study found that DNR rates varied across cancer types and decreased in cancer patients with concomitant chronic dialysis or ventilator use. Disparities in DNR rates were evident across geographic regions in Taiwan. A wider adoption of the DNR policy may achieve substantial savings in health expenses and improve patients’ quality of life.

A systematic review of proactive psychiatric consultation on hospital length of stay

OBJECTIVE

Roughly half of general hospital patients may have a psychiatric issue that impacts care, yet most of these are not recognized during hospital admission. Proactive mental health screening offers an opportunity for timely identification and clinical attention to improve outcomes.

METHOD

We conducted a PRISMA systematic review of Pubmed, Embase, PsycINFO, and Cochrane Library for proactive models of psychiatric consultation to reduce hospital length of stay (LOS) in adult inpatients. For each study, we evaluated the level of evidence and defined the study sample, means of group allocation, screening process, interventions, and outcomes.

RESULTS

Of the 12 included studies, the 8 whose screening was informed by clinicians with mental health care expertise or whose providers were integrated with primary services reported a reduction in LOS. Two of these also reported favorable cost-benefit analyses. All positive studies represent versions of either psychiatrists embedded within medical or surgical settings or a multidisciplinary team-based model.

CONCLUSIONS

Proactive CL psychiatry with clinically-informed screening and integrated care delivery appear to reduce LOS. Further studies are needed to explore a broader range of outcomes, hospital populations beyond hospital medicine, and additional benefits of proactive integrated mental health care in the general hospital.

Characteristics, Outcomes, and Cost Patterns of High-Cost Patients in the Intensive Care Unit

Background

ICU care is costly, and there is a large variation in cost among patients.

Methods

This is an observational study conducted at two ICUs in an academic centre. We compared the demographics, clinical data, and outcomes of the highest decile of patients by total costs, to the rest of the population.

Results

A total of 7,849 patients were included. The high-cost group had a longer median ICU length of stay (26 versus 4 days, P < 0.001) and amounted to 49% of total costs. In-hospital mortality was lower in the high-cost group (21.1% versus 28.4%, P < 0.001). Fewer high-cost patients were discharged home (23.9% versus 45.2%, P < 0.001), and a large proportion were transferred to long-term care (35.1% versus 12.1%, P < 0.001). Patients with younger age or a diagnosis of subarachnoid hemorrhage, acute respiratory failure, or complications of procedures were more likely to be high cost.

Conclusions

High-cost users utilized half of the total costs. While cost is associated with LOS, other drivers include younger age or admission for respiratory failure, subarachnoid hemorrhage, or after a procedural complication. Cost-reduction interventions should incorporate strategies to optimize critical care use among these patients.
