Assessing the Feasibility and Implementation of Palliative Care Triggers in a Surgical Intensive Care Unit to Improve Interdisciplinary Collaboration for Patient and Family Care

Although palliative care focuses on supporting patients and families through serious illness, it is underutilized in the surgical intensive care unit (SICU). In 2020, patients in the SICU represented only 2.75% of our palliative team's consults. We hypothesize that utilization of palliative care triggers in the SICU will increase collaboration between SICU and palliative care teams and improve patient/family experiences. After reviewing our team's consultation records and the published literature, a consult trigger program was implemented for patients with a SICU length of stay >10 days, unplanned SICU readmission, or new diagnosis of metastatic cancer. A pre-intervention survey assessed SICU providers' perceptions of palliative care. Retrospective analysis evaluated qualitative and quantitative measures. 97% of SICU providers felt increased palliative care would be helpful. During the 6-month project, January 1, 2021 - June 30, 2021, our palliative team performed 27 triggered consults, representing 3.3% of the total 818 consults performed during this period and thus a 20% increase in SICU palliative consults. Triggered consults represented many primary surgical services and the most common consult reason was length-of-stay. All consults included discussions about goals of care and 16 of the 27 patients/families expressed restorative goals. Numerous notes documented family appreciation.

Neurosurgical Outcomes in Severe Traumatic Brain Injuries Between Service Lines: Review of a Single Institution Database

Severe traumatic injury (sTBI) continues to be a common source of morbidity and mortality. While there have been several advances in understanding the pathophysiology of this injury, the clinical outcome has remained grim. These trauma patients often require multidisciplinary care and are admitted to a surgical service line, depending on hospital policy. A retrospective chart review spanning 2019-2022 was completed using the electronic health record of the neurosurgery service. We identified 140 patients with a Glasgow Coma Scale (GCS) of eight or less, ages 18-99, who were admitted to a level-one trauma center in Southern California. Seventy patients were admitted under the neurosurgery service, while the other half were admitted to the surgical intensive care unit (SICU) service after initial assessment in the emergency department by both services to evaluate for multisystem injury. Between both groups, the injury severity scores that evaluated patients' overall injuries were not significantly different. The results demonstrate a significant difference in GCS change, modified Rankin Scale (mRS) change, and Glasgow Outcome Scale (GOS) change between the two groups. Furthermore, the mortality rate differed between neurosurgical care and other service care by 27% and 51%, respectively, despite similar Injury Severity Scores (ISS) (p=0.0026). Therefore, this data demonstrates that a well-trained neurosurgeon with critical care experience can safely manage a severe traumatic brain injury patient with an isolated head injury as a primary service while in the intensive care unit. Since injury severity scores did not differ between these two service lines, we further theorize that this is likely due to a deep understanding of the nuances of neurosurgical pathophysiology and Brain Trauma Foundation (BTF) guidelines.

Closed-PICU perioperative management of congenital tracheal stenosis

BACKGROUND

Perioperative management of congenital tracheal stenosis (CTS) is challenging. In the present study, compared the effect of closed-pediatric intensive care unit (PICU) perioperative management by pediatric intensivists and open-PICU management by surgeons. Outcomes in terms of ventilator-free days (VFD) and length of postoperative PICU stay in children with CTS were evaluated.

METHODS

This retrospective cohort study was conducted in a PICU in Japan. Children with CTS who underwent slide tracheoplasty were grouped according to whether they were perioperatively managed in an open (January 2015 to April 2016) or a closed (May 2016 to August 2019) PICU. Data were extracted from patients' medical records.

RESULTS

In total, 13 and 38 patients were included in the open- and closed-PICU groups, respectively. Compared to the open-PICU group, the closed-PICU group had shorter duration of muscle relaxant administration (median 4 vs 5 days; P < 0.001), earlier enteral nutrition (34/38 [90%] vs 1/13 [8%]; P < 0.001), more 28-day VFD (median 21 vs 20 days; P = 0.04), and shorter duration of postoperative PICU stay (median 16 vs 36 days; P = 0.002), but mortality did not differ significantly between the two groups (0/38 [0%] vs 1/13 [8%]; P = 0.25).

CONCLUSIONS

Closed-PICU perioperative management with pediatric intensivists' participation significantly increased 28-day VFD and reduced the length of postoperative PICU stay in patients with congenital tracheal stenosis.

Type of underlying fracture after the surgical treatment of geriatric trauma patients has no effect on mortality during intensive care treatment

AIM

Due to demographic change, the number of geriatric patients is still rising. Although hip fractures are the subject of current research, little is known about the remaining geriatric trauma entities. The aim of this study was to collect data of the age-related traumatological intensive care unit (ICU) population, its underlying diagnosis, and the influence on mortality and length of stay in the ICU.

METHODS

Geriatric trauma patients (aged ≥65 years) treated postoperatively in our surgical ICU were included in this retrospective observational study covering the period 2013-2017. In addition to the underlying fracture entities, patient characteristics, such as age, sex, Charlson Comorbidity Index, length of stay and mortality, were collected to identify possible independent predictive factors for mortality in the ICU using multivariate analysis.

RESULTS

During the observation period, 805 (60.5%) patients met the inclusion criteria. 47.6% of the patients suffered from a proximal femoral fracture. The total mortality rate during the stay in the ICU was 7.5%. Significant predictive factors for mortality in the ICU were Charlson Comorbidity Index (P < 0.001) and length of stay (P < 0.001). The different fracture types themselves were not a significant risk factor for mortality (P = 0.862).

CONCLUSION

Patients with proximal femoral fractures account for approximately half of the patients in intensive care. The mortality rate of these patients is no higher than that in geriatric trauma patients with other fractures. The progression is essentially influenced by the patient's comorbidities. Nowadays, the focus shifts from trauma care to the therapy of concomitant diseases. Nevertheless, this cohort, when adequately treated, shows a comparatively low mortality rate.

Barriers to High Quality End of Life Care in the Surgical Intensive Care Unit

End of life discussions frequently take place in surgical intensive care units, as a significant number of patients die while admitted to the hospital, and surgery is common during the last month of life. Multiple barriers exist to the initiation of these conversations, including: miscommunication between clinicians and surrogates, a paternalistic approach to surgical patients, and perhaps, conflicts of interest as an unwanted consequence of surgical quality reporting. Goal discordant care refers to the care that is provided to a patient that is incapacitated and that is not concordant to his/her wishes. This is a largely unrecognized medical error with devastating consequences, including inappropriate prolongation of life and non-beneficial therapy utilization. Importantly, hospice and palliative care needs to be recognized as quality care in order to deter the incentives that might persuade clinicians from offering these services.

Evaluating ethical sensitivity in surgical intensive care nurses

BACKGROUND AND AIM

Surgical intensive care nurses should have ethical sensitivity allowing them to identify ethical issues in order that they can recognize them and make the right decisions. This descriptive study was conducted with the aim of evaluating the ethical sensitivity of surgical intensive care nurses.

MATERIALS AND METHODS

The research was carried out with the participation of 160 nurses in six Turkish hospitals, four state, one university, and one private. The data were collected using the "Nurse Description Form" developed by the researcher and the "Ethical Sensitivity Questionnaire." The percent, mean, standard deviation, median, minimum and maximum values, significance test for the difference between two means, variance analysis, Mann-Whitney U test, and Kruskal-Wallis Variance Analysis test were used to evaluate the data.

ETHICAL CONSIDERATIONS

Ethical commission permission and the corporate permission of the hospitals were received before conducting the research.

RESULTS

It was determined that the ethical sensitivities of surgical intensive care nurses were moderate based on the Ethical Sensitivity Questionnaire total score and subdimension score averages. A statistical difference was determined between the Ethical Sensitivity Questionnaire total score of surgical intensive care nurses and the institution where they worked, the period of working in the occupation, and the period of working in the intensive care unit (p < 0.05).

CONCLUSION

Based on the results of the research, the organization of training and studies devoted to the elimination of ethical sensitivity differences between institutions and workers is suggested.

The Use of Lung Ultrasound in a Surgical Intensive Care Unit

Background

Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU).

Methods

This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016.

Results

The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively.

Conclusions

LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

Outcomes of post-cardiac surgery patients with persistent hyperlactatemia in the intensive care unit: a matched cohort study

BACKGROUND

Higher morbidity and mortality rates are seen amongst patients presenting with hyperlactatemia in the postoperative period. The purpose of this study was to determine the relationship between persistent elevations in lactate and poor ICU outcome in post-cardiac surgery patients.

METHODS

This was a retrospective matched cohort analysis of cardiac surgery patients undergoing bypass and/or valve surgery in a university hospital centre. Selection criteria were: cardiac bypass and/or valve surgery; admission to the ICU for > 24 h postoperatively; and peak lactate ≥ 3.0 mmol/L. Hyperlactatemic patients were matched to 2 normolactatemic patients. Multivariable conditional logistic regression was used to determine predictors of hyperlactatemia and mortality.

RESULTS

Four hundred sixty-nine post-cardiac surgery patients were admitted to the ICU for > 24 h. 144 of these patients had an arterial blood lactate ≥ 3.0 mmol/L. Amongst the mortalities, 78.9 % presented with hyperlactatemia. Independent risk factors predictive of a lactate ≥ 3.0 mmol/L were preoperative IABP insertion (RR 2.8, CI 1.1-7.2) and postoperative acute kidney injury (RR 3.2, CI 2.1-5.4). Patients whose lactate concentrations continued to increase >30 h postoperatively were more likely to die (RR 8.44 CI 2.50-28.53).

CONCLUSIONS

The persistence of hyperlactatemia is a more important determinant of postoperative outcome than the absolute value of the peak lactate concentration. A simple postoperative lactate washout does not sufficiently explain this lactate accumulation. Mortality is proposed to be secondary to a state of ongoing hypoperfusion.

Early extubation and fast-track management of off-pump cardiac patients in the intensive care unit

Off-pump surgery was the original approach to treating patients with cardiac disease in the era before cardiopulmonary bypass. With the advent and refinement of cardiopulmonary bypass, the use of this technique fell out of favor and was quickly surpassed by on-pump techniques. However, the limitations of bypass surgery, especially for coronary artery bypass procedures, was still significant, leading to renewed interest in this technique. Postoperative care for off-pump coronary artery bypass (OPCAB) surgery presents both a challenge and opportunity to the intensivist. OPCAB patients can be treated in a fast-track manner allowing rapid recovery and early extubation and discharge from the intensive care unit. This is supported through the use of protocols that help standardize care and set expectations for the post-cardiac care team. Importantly, complications that may delay recovery including hypothermia, hypotension, and bleeding must be recognized early and treated aggressively to prevent unwanted complications and intensive care delays. Finally, care of these patients has shifted to the post-anesthesia recovery room, making knowledge of the care of these patients in the early postoperative period essential for cardiac anesthesiologists. This article will discuss the care of OPCAB patients following surgery and include approaches to managing patients who return both intubated and extubated.

Quality Outcomes in the Surgical Intensive Care Unit after Electronic Health Record Implementation

BACKGROUND

The electronic health record (EHR) is increasingly viewed as a means to provide more coordinated, patient-centered care. Few studies consider the impact of EHRs on quality of care in the intensive care unit (ICU) setting.

OBJECTIVES

To evaluate key quality measures of a surgical intensive care unit (SICU) following implementation of the Epic EHR system in a tertiary hospital.

METHODS

A retrospective chart review was undertaken to record quality indicators for all patients admitted to the SICU two years before and two years after EHR implementation. Data from the twelve-month period of transition to EHR was excluded. We collected length of stay, mortality, central line associated blood stream infection (CLABSI) rates, Clostridium difficile (C. diff.) colitis rates, readmission rates, and number of coded diagnoses. To control for variation in the patient population over time, the case mix indexes (CMIs) and APACHE II scores were also analyzed.

RESULTS

There was no significant difference in length of stay, C. diff. colitis, readmission rates, or case mix index before and after EHR. After EHR implementation, the rate of central line blood stream infection (CLABSI) per 1 000 catheter days was 85% lower (2.16 vs 0.39; RR, 0.18; 95% CI, 0.05 to 0.61, p < .005), and SICU mortality was 28% lower (12.2 vs 8.8; RR, 1.35; 95% CI, 1.06 to 1.71, p < .01). Moreover, after EHR there was a significant increase in the average number of coded diagnoses from 17.8 to 20.8 (p < .000).

CONCLUSIONS

EHR implementation was statistically associated with reductions in CLABSI rates and SICU mortality. The EHR had an integral role in ongoing quality improvement endeavors which may explain the changes in CLABSI and mortality, and this invites further study of the impact of EHRs on quality of care in the ICU.

Invasive Candida infections in surgical patients in intensive care units: a prospective, multicentre survey initiated by the European Confederation of Medical Mycology (ECMM) (2006-2008)

A prospective, observational, multicentre study of invasive candidosis (IC) in surgical patients in intensive care units (ICUs) was conducted from 2006 to 2008 in 72 ICUs in 14 European countries. A total of 779 patients (62.5% males, median age 63 years) with IC were included. The median rate of candidaemia was 9 per 1000 admissions. In 10.8% the infection was already present at the time of admission to ICU. Candida albicans accounted for 54% of the isolates, followed by Candida parapsilosis 18.5%, Candida glabrata 13.8%, Candida tropicalis 6%, Candida krusei 2.5%, and other species 5.3%. Infections due to C. krusei (57.9%) and C. glabrata (43.6%) had the highest crude mortality rate. The most common preceding surgery was abdominal (51.5%), followed by thoracic (20%) and neurosurgery (8.2%). Candida glabrata was more often isolated after abdominal surgery in patients ≥60 years, and C. parapsilosis was more often isolated in neurosurgery and multiple trauma patients as well as children ≤1 year of age. The most common first-line treatment was fluconazole (60%), followed by caspofungin (18.7%), liposomal amphotericin B (13%), voriconazole (4.8%) and other drugs (3.5%). Mortality in surgical patients with IC in ICU was 38.8%. Multivariate analysis showed that factors independently associated with mortality were: patient age ≥60 years (hazard ratio (HR) 1.9, p 0.001), central venous catheter (HR 1.8, p 0.05), corticosteroids (HR 1.5, p 0.03), not receiving systemic antifungal treatment for IC (HR 2.8, p <0.0001), and not removing intravascular lines (HR 1.6, p 0.02).

There's no place like home: boarding surgical ICU patients in other ICUs and the effect of distances from the home unit

BACKGROUND

Intensive care units (ICUs) function frequently at capacity, requiring incoming critically ill patients to be placed in alternate geographically distinct ICUs. In some medical ICU populations, "boarding" in an overflow ICU has been associated with increased mortality. We hypothesized that surgical ICU patients experience more complications when boarding in an overflow ICU and that the frequency of these complications are greatest in boarders farthest from the home unit (HU).

METHODS

A 5-year (June 2005 to June 2010) retrospective review of a prospectively maintained ICU database was performed, and demographics, severity of illness, length of stay, and incidence of ICU complications were extracted. Distances between boarding patients' rooms and the HU were measured. Complications occurring in patients located in the same floor (BUSF) and different floor (BUDF) boarding units were compared and stratified by distance from HU to the patient room. Logistic regression was used to develop control for known confounders.

RESULTS

A total of 7,793 patients were admitted to the HU and 833 to a boarding unit (BUSF, n = 712; BUDF, n = 121). Boarders were younger, had a lower length of stay, and Acute Physiology and Chronic Health Evaluation II and were more often trauma/emergency surgery patients. Compared with in-HU patients, the incidence of aspiration pneumonia (2.2% vs. 3.6%, p < 0.01) was greater in BUSF patients and highest in those farthest from the HU (odds ratio [OR], 2.39; p = 0.01). Delirium occurred less often in HU than in BUDF patients (3.3% vs. 8.3 %, p < 0.01), and both delirium (OR, 6.09, p < 0.01) and ventilator-associated pneumonia (OR, 4.49, p < 0.05) were more frequent in patients farther from the HU.

CONCLUSION

Certain ICU complications occur more frequently in boarding patients particularly if they are located on a different floor or far from the HU. When surgical ICU bed availability forces overflow admissions to non-home ICUs, greater interdisciplinary awareness, education, and training may be needed to ensure equivalent care and outcomes.

Persistent inflammation and immunosuppression: a common syndrome and new horizon for surgical intensive care

Surgical intensive care unit (ICU) stay of longer than 10 days is often described by the experienced intensivist as a "complicated clinical course" and is frequently attributed to persistent immune dysfunction. "Systemic inflammatory response syndrome" (SIRS) followed by "compensatory anti-inflammatory response syndrome" (CARS) is a conceptual framework to explain the immunologic trajectory that ICU patients with severe sepsis, trauma, or emergency surgery for abdominal infection often traverse, but the causes, mechanisms, and reasons for persistent immune dysfunction remain unexplained. Often involving multiple-organ failure (MOF) and death, improvements in surgical intensive care have altered its incidence, phenotype, and frequency and have increased the number of patients who survive initial sepsis or surgical events and progress to a persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Often observed, but rarely reversible, these patients may survive to transfer to a long-term care facility only to return to the ICU, but rarely to self-sufficiency. We propose that PICS is the dominant pathophysiology and phenotype that has replaced late MOF and prolongs surgical ICU stay, usually with poor outcome. This review details the evolving epidemiology of MOF, the clinical presentation of PICS, and our understanding of how persistent inflammation and immunosuppression define the pathobiology of prolonged intensive care. Therapy for PICS will involve innovative interventions for immune system rebalance and nutritional support to regain physical function and well-being.
