Hospital-level variation in the development of persistent critical illness

Interhospital variation in the non-operative management of uncomplicated appendicitis in adults

Background

Recent randomized trials have suggested non-operative management to be a safe alternative to appendectomy for acute uncomplicated appendicitis. Yet, there remains significant variability in treatment approach. This study sought to characterize center-level variation in non-operative management within a national cohort of adults presenting with appendicitis.

Methods

The 2016-2020 Nationwide Readmissions Database was queried to identify all adult (≥18 years) hospitalizations for acute uncomplicated appendicitis. Hierarchical, mixed-effects models were developed to ascertain factors linked with non-operative management. Bayesian methodology was applied to predict random effects, which were then used to rank centers by increasing hospital-attributed rate of non-operative management. Institutions with high center-specific rates of non-operative management (>90th percentile) were considered low-operating hospitals (LOH).

Results

Of an estimated 447,500 patients, 52,523 (11.7 %) were managed non-operatively. Compared to those undergoing appendectomy, the non-operative cohort was older, more commonly male, and of a higher comorbidity burden. Approximately 30 % in the variability of non-operative management was attributable to hospital effects, with absolute, risk-adjusted rates ranging from 0.5 to 22.5 %. Centers with non-operative management rates ≥90th percentile were considered LOH.Following risk adjustment, among patients undergoing appendectomy, care at LOH was linked with greater odds of postoperative infection, resource utilization, and non-elective readmission.

Conclusions

We identified significant interhospital variation in the utilization of non-operative management for acute uncomplicated appendicitis. Further, we found LOH to be associated with inferior outcomes following surgical management. Future work is needed to assess the care pathways that contribute to increased utilization of non-operative strategies, and disseminate best practices across institutions.

Center-level variation in hospitalization costs of pancreaticoduodenectomy for pancreatic cancer

BACKGROUND

Pancreaticoduodenectomy is a highly morbid operation with significant resource utilization. Using a national cohort, we examined the interhospital variation in pancreaticoduodenectomy hospitalization cost in the United States.

METHODS

Adults undergoing elective pancreaticoduodenectomy in the setting of pancreatic cancer were tabulated from the 2016-2020 Nationwide Readmissions Database. A 2-level mixed-effects model was developed to evaluate the interhospital variation in pancreaticoduodenectomy hospitalization costs. Institutions within the top decile of risk-adjusted expenditures were defined as high-cost hospitals. Multivariable regression models were fitted to examine the association between high-cost hospital status and outcomes of interest. To account for the effects of complications on expenditures, a subgroup analysis comprising of patients with no adverse events was conducted.

RESULTS

The study included an estimated 24,779 patients with a median hospitalization cost of $38,800. After mixed-effects modeling, 40.9% of the cost variation was attributable to hospital, rather than patient, factors. Multivariable regression models revealed an association between high-cost hospital status and greater odds of complications and longer length of stay. Among patients without an adverse event, interhospital cost variation remained significant at 61.0%, and treatment at high-cost hospitals was similarly linked to longer length of stay.

CONCLUSION

Our study identified significant interhospital variation in pancreaticoduodenectomy hospitalization costs in the United States. Although high-cost hospital status was associated with increased odds of complications, variation remained significant even among patients without an adverse event. These results suggest the important role of hospital practices as contributors to expenditures. Further efforts to identify drivers of costs and standardize pancreatic surgical care are warranted.

Interhospital variation in the nonoperative management of acute cholecystitis

BACKGROUND

Cholecystectomy remains the standard management for acute cholecystitis. Given that rates of nonoperative management have increased, we hypothesize the existence of significant hospital-level variability in operative rates. Thus, we characterized patients who were managed nonoperatively at normal and lower operative hospitals (>90th percentile).

METHODS

All adult admissions for acute cholecystitis were queried using the 2016-2019 Nationwide Readmissions Database. Centers were ranked by nonoperative rate using multi-level, mixed effects modeling. Hospitals in the top decile of nonoperative rate (>9.4%) were classified as Low Operative Hospitals (LOH; others:nLOH). Separate regression models were created to determine factors associated with nonoperative management at LOH and nLOH.

RESULTS

Of an estimated 418,545 patients, 9.9% were managed at 880 LOH. Multilevel modeling demonstrated that 20.6% of the variability was due to hospital factors alone. After adjustment, older age (Adjusted Odds Ratio [AOR] 1.02/year, 95% Confidence Interval [CI] 1.01-1.02) and public insurance (Medicare AOR 1.31, CI 1.21-1.43 and Medicaid AOR 1.43, CI 1.31-1.57; reference: Private Insurance) were associated with nonoperative management at LOH. These were similar at nLOH. At LOH, SNH status (AOR 1.17, CI 1.07-1.28) and small institution size (AOR 1.20, CI 1.09-1.34) were associated with increased odds of nonoperative management.

CONCLUSION

We noted a significant variability in the interhospital variation of the nonoperative management of acute cholecystitis. Nevertheless, comparable clinical and socioeconomic factors contribute to nonoperative management at both LOH and non-LOH. Directed strategies to address persistent non-clinical disparities are necessary to minimize deviation from standard protocol and ensure equitable care.

Urea to creatinine ratio as a predictor of persistent critical illness

INTRODUCTION

Persistent critical illness (PCI) is a syndrome in which the acute presenting problem has been stabilized, but the patient's clinical state does not allow ICU discharge. The burden associated with PCI is substantial. The most obvious marker of PCI is prolonged ICU length of stay (LOS), usually greater than 10 days. Urea to Creatinine ratio (UCr) has been suggested as an early marker of PCI development.

METHODS

A single-center retrospective study. Data of patients admitted to a general mixed medical-surgical ICU during Jan 1st 2018 till Dec 31st 2022 was extracted, including demographic data, baseline characteristics, daily urea and creatinine results, renal replacement therapy (RRT) provided, and outcome measures - length of stay, and mortality (ICU, and 90 days). Patients were defined as PCI patients if their LOS was >10 days. We used Fisher exact test or Chi-square to compare PCI and non-PCI patients. The association between UCr with PCI development was assessed by repeated measures linear model. Multivariate Cox regression was used for 1 year mortality assessment.

RESULTS

2098 patients were included in the analysis. Patients who suffered from PCI were older, with higher admission prognostic scores. Their 90-day mortality was significantly higher than non-PCI patients (34.58% vs 12.18%, p < 0.0001). A significant difference in UCr was found only on the first admission day among all patients. This was not found when examining separately surgical, trauma, or transplantation patients. We did not find a difference in UCr in different KDIGO (Kidney Disease Improving Global Outcomes) stages. Elevated UCr and PCI were found to be significantly associated with 1 year mortality.

CONCLUSION

In this single center retrospective cohort study, UCr was not found to be associated with PCI development.

Cost variation of nonelective surgery for ulcerative colitis across the United States

BACKGROUND

Although clinical outcomes of surgery for ulcerative colitis (UC) have improved in the modern biologic era, expenditures continue to increase. A contemporary cost analysis of UC operative care is lacking. The present study aimed to characterize risk factors and center-level variation in hospitalization costs after nonelective resection for UC.

METHODS

All adults with UC in the 2016-2020 Nationwide Readmissions Database undergoing nonelective colectomy or rectal resection were identified. Mixed-effects models were developed to evaluate patient and hospital factors associated with costs. Random effects were estimated and used to rank hospitals by increasing risk-adjusted center-level costs. High-cost hospitals (HCHs) in the top decile of expenditure were identified, and their association with select outcomes was subsequently assessed.

RESULTS

An estimated 10,280 patients met study criteria with median index hospitalization costs of $40,300 (IQR, $26,400-$65,000). Increased time to surgery was significantly associated with a +$2500 increment in costs per day. Compared with low-volume hospitals, medium- and high-volume centers demonstrated a -$5900 and -$8200 reduction in costs, respectively. Approximately 19.2% of variability in costs was attributable to interhospital differences rather than patient factors. Although mortality and readmission rates were similar, HCH status was significantly associated with increased complications (adjusted odds ratio [AOR], 1.39), length of stay (+10.1 days), and nonhome discharge (AOR, 1.78).

CONCLUSION

The present work identified significant hospital-level variation in the costs of nonelective operations for UC. Further efforts to optimize time to surgery and regionalize care to higher-volume centers may improve the value of UC surgical care in the United States.

Prolonged Mechanical Ventilation, Weaning, and the Role of Tracheostomy

Depending on the definitional criteria used, approximately 5% to 10% of critical adults will require prolonged mechanical ventilation with longer-term outcomes that are worse than those ventilated for a shorter duration. Outcomes are affected by patient characteristics before critical illness and its severity but also by organizational characteristics and care models. Definitive trials of interventions to inform care activities, such as ventilator weaning, upper airway management, rehabilitation, and nutrition specific to the prolonged mechanical ventilation patient population, are lacking. A structured and individualized approach developed by the multiprofessional team in discussion with the patient and their family is warranted.

Center-Level Variation in Hospitalization Costs of Transcatheter Aortic Valve Replacement

BACKGROUND

Using a nationally representative database, the present study evaluated the degree of center-level variation in the cost of transcatheter aortic valve replacement (TAVR).

METHODS

All adults undergoing elective, isolated TAVR were identified in the 2016 to 2018 Nationwide Readmissions Database. Multilevel mixed-effects models were used to identify patient and hospital characteristics associated with hospitalization costs. The random intercept for each hospital was generated and considered to be the baseline cost attributable to care at each center. Hospitals in the highest decile of baseline costs were classified as high-cost hospitals. The association of high-cost hospital status with in-hospital mortality and perioperative complications was subsequently assessed.

RESULTS

An estimated 119,492 patients, with a mean age of 80 years and a 45.9% prevalence of female sex, met the study criteria. Analysis of random intercepts indicated that 54.3% of variability in costs was attributable to interhospital differences rather than patient factors. Perioperative respiratory failure, neurologic complications, and acute kidney injury were associated with increased episodic expenditure but did not explain the observed center-level variation. The baseline cost associated with each hospital ranged from -$26,000 to $162,000. Notably, high-cost hospital status was not linked to annual TAVR caseload or to odds of mortality (P = .83), acute kidney injury (P = .18), respiratory failure (P = .32), or neurologic complications (P = .55).

CONCLUSIONS

The present analysis identified significant variation in the cost of TAVR, which was largely attributable to center-level rather than patient factors. Hospital TAVR volume and occurrence of complications were not drivers of the observed variation.

Clinician views on actionable processes of care for prolonged stay intensive care patients and families: A descriptive qualitative study

OBJECTIVES

To explore clinician perspectives on key actionable processes of care that may improve outcomes and experience of patients experiencing a prolonged (over 7 days) intensive care unit stay, and their family members.

RESEARCH METHODOLOGY

A descriptive qualitative interview study in the United Kingdom. We conducted online semi-structured interviews using video conferencing software (October 2020-August 2022). We used purposive sampling ensuring participation from a broad range of professions representing the interprofessional team in the United Kingdom. We used Framework Analysis methods to group actionable processes into the six themes of person-centred care. Analyses were informed by our previous scoping review and previous interviews with former patients and family members.

FINDINGS

We interviewed 24 staff participants and identified 36 actionable processes of care under six themes of person-centred care. Processes relating to communication (both establishing an effective communication method for the patient and staff communication with the patient and family), continuity of staff and care plans, and personalising the environment and routines, and allowing flexible family visiting were most frequently articulated. These processes were perceived as having a multifaceted impact on patient and family wellbeing, for example family visiting helping patient and family emotional wellbeing and staff communication with family; and establishing an effective communication method for patients reduced their anxiety, enhanced their involvement in their care and allowed staff to include them in ward rounds more efficiently.

CONCLUSION

We identified 36 actionable processes of care from interviews with intensive care staff, with an emphasis on enhancing patient autonomy through optimising communication and involvement in decision-making, participation of family, and continuity of staff and care plans.

IMPLICATIONS FOR CLINICAL PRACTICE

These 36 actionable processes of care will contribute to future development of quality improvement tools, which will be used to standardise the care of prolonged-stay intensive care patients and their families.

Expanded Criteria Donor Heart Allograft Utilization: National Trends and Outcomes

BACKGROUND

To examine recent trends in the use of expanded criteria donor organs in heart transplantation, this study assessed center-level variation in acceptance of these allografts and analyzed their posttransplantation outcomes.

METHODS

Adult (aged ≥18 years) heart transplant recipients between 2011 and 2022 were identified in the Organ Procurement and Transplantation Network database. Expanded criteria allografts were defined using a previously validated risk score. After stratifying centers by cumulative transplantation volume, those centers in the top tertile (≥23/year) were considered high volume. Subsequently, the ratio of transplantations using expanded criteria allografts to total transplantations was calculated for each high-volume center. On the basis of tertiles, centers were then categorized as high-, medium-, and low-use centers. The primary outcome was death after transplantation.

RESULTS

Of 23,290 transplantations performed, 5017 (22%) used expanded criteria donor allografts. High-volume heart transplantation centers performed 72% (3628) of these transplantations-1183 (75%) between 2011 and 2014, 1383 (73%) between 2015 and October 2018, and 1062 (68%) between November 2018 and June 2021. Compared with low-volume programs, undergoing expanded criteria heart transplantation at high-volume centers was associated with a significantly reduced hazard of mortality at 1 year (hazard ratio, 0.78; CI, 0.65-0.94; P = .01) and 5 years (hazard ratio, 0.85; CI, 0.75-0.98; P = .02). During the study period, survival rates 1 year after transplantation were similar across high-volume centers, regardless of their use of expanded criteria allografts.

CONCLUSIONS

Undergoing heart transplantation with an expanded criteria donor allograft at a high-volume transplantation center provides a significant survival benefit. Further, the use of more expanded criteria criteria organs, in the right clinical settings, does not negatively affect overall patient outcomes at high-volume centers.

Cost Variation in Bariatric Surgery Across the United States

BACKGROUND

High costs have been cited as a barrier to utilization of bariatric surgery despite the increasing prevalence of obesity in the United States. The present work characterizes the center-level variation and risk factors for increased hospitalization costs following bariatric operations.

STUDY DESIGN

The 2016-2019 Nationwide Readmissions Database was queried to identify all adults undergoing elective laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). Random effects were estimated using Bayesian methodology and used to rank hospitals by increasing risk-adjusted center-level costs.

RESULTS

Of an estimated 687,866 patients at an annual 2435 hospitals, 69.9% underwent SG and 30.1% RYGB, with median costs of $10,900 (interquartile range: 8600-14,000) and $13,600 (10,300-18,000), respectively. Hospitals in the highest tertile of annual SG and RYGB volume were associated with a $1500 (95% CI - 2,100, -800) and $3400 reduction in costs (95% CI -4,200, -2600). Approximately 37.2% (95% CI 35.8-38.6) of variation in hospitalization costs was attributable to the hospital. Hospitals in the top decile of center-level costs were associated with increased odds of developing complications (AOR 1.22, 95% CI 1.05-1.40) but not mortality.

CONCLUSION

The present work identified significant interhospital variation in the costs of bariatric operations. Further efforts to standardize costs may enhance the value of bariatric surgical care in the US.

Evaluation of hospital readmission rates as a quality metric in adult cardiac surgery

OBJECTIVE

To assess the reliability of 30-day non-elective readmissions as a quality metric for adult cardiac surgery.

BACKGROUND

Unplanned readmissions is a quality metric for adult cardiac surgery. However, its reliability in benchmarking hospitals remains under-explored.

METHODS

Adults undergoing elective isolated coronary artery bypass grafting (CABG), surgical aortic valve replacement/repair (SAVR) or mitral valve replacement/repair (MVR) were tabulated from 2019 Nationwide Readmissions Database. Multi-level regressions were developed to model the likelihood of 30-day unplanned readmissions and major adverse events (MAE). Random intercepts were estimated, and associations between hospital-specific risk-adjusted rates of readmissions and were assessed using the Pearson correlation coefficient (r).

RESULTS

Of an estimated 86 024 patients meeting study criteria across 298 hospitals, 62.6% underwent CABG, 22.5% SAVR and 14.9% MVR. Unadjusted readmission rates following CABG, SAVR and MVR were 8.4%, 9.3% and 11.8%, respectively. Unadjusted MAE rates following CABG, SAVR and MVR were 35.1%, 32.3% and 37.0%, respectively. Following adjustment, interhospital differences accounted for 4.1% of explained variance in readmissions for CABG, 7.6% for SAVR and 10.0% for MVR. There was no association between readmission rates for CABG and SAVR (r=0.10, p=0.09) or SAVR and MVR (r=0.09, p=0.1). A weak association was noted between readmission rates for CABG and MVR (r=0.20, p<0.001). There was no significant association between readmission and MAE for CABG (r=0.06, p=0.2), SAVR (r=0.04, p=0.4) and MVR (r=-0.03, p=0.6).

CONCLUSION

Our findings suggest that readmissions following adult cardiac surgery may not be an ideal quality measure as hospital factors do not appear to influence this outcome.

Acute clinical and financial outcomes of esophagectomy at safety-net hospitals in the United States

BACKGROUND

While safety-net hospitals (SNH) play a critical role in the care of underserved communities, they have been associated with inferior postoperative outcomes. This study evaluated the association of hospital safety-net status with clinical and financial outcomes following esophagectomy.

METHODS

All adults (≥18 years) undergoing elective esophagectomy for benign and malignant gastroesophageal disease were identified in the 2010-2019 Nationwide Readmissions Database. Centers in the highest quartile for the proportion of uninsured/Medicaid patients were classified as SNH (others: non-SNH). Regression models were developed to evaluate adjusted associations between SNH status and outcomes, including in-hospital mortality, perioperative complications, and resource use. Royston-Parmar flexible parametric models were used to assess time-varying hazard of non-elective readmission over 90 days.

RESULTS

Of an estimated 51,649 esophagectomy hospitalizations, 9,024 (17.4%) were performed at SNH. While SNH patients less frequently suffered from gastroesophageal malignancies (73.2 vs 79.6%, p<0.001) compared to non-SNH, the distribution of age and comorbidities were similar. SNH was independently associated with mortality (AOR 1.24, 95% CI 1.03-1.50), intraoperative complications (AOR 1.45, 95% CI 1.20-1.74) and need for blood transfusions (AOR 1.61, 95% CI 1.35-1.93). Management at SNH was also associated with incremental increases in LOS (+1.37, 95% CI 0.64-2.10), costs (+10,400, 95% CI 6,900-14,000), and odds of 90-day non-elective readmission (AOR 1.11, 95% CI 1.00-1.23).

CONCLUSIONS

Care at safety-net hospitals was associated with higher odds of in-hospital mortality, perioperative complications, and non-elective rehospitalization following elective esophagectomy. Efforts to provide sufficient resources at SNH may serve to reduce complications and overall costs for this procedure.

Timing and burden of persistent critical illnessin UK intensive care units: An observational cohort study

Background

Persistent critical illness is a recognisable clinical syndrome defined conceptually as when the patient's reason for being in the intensive care unit (ICU) is more related to their ongoing critical illness than their original reason for admission. Our objectives were: (1) to assess the day in ICU on which chronic factors (e.g., age, gender and comorbidities) were more predictive of survival than acute factors (e.g. admission diagnosis, physiological derangements) measured on the day of admission; (2) to assess the consistency of this finding across major patient subgroups and over time and (3) to compare case mix characteristics and outcomes for patients determined to develop persistent critical illness (based on ICU length of stay) with other patients.

Methods

Observational cohort study using a high-quality clinical database from the national clinical audit of adult critical care. 217 adult ICUs in England, Wales and Northern Ireland. 835,946 adult patients admitted to participating ICUs between 1 April 2009 and 31 March 2016. The main outcome measure was mortality at discharge from acute hospital.

Results

We fitted two statistical models ('chronic' and 'acute') and updated these based upon patients with an ICU length of stay of at least 1, 2, etc., up to 28 days. The discrimination of the chronic model first exceeded that of the acute model on day 11. Patients with longer stays (>10 days) comprised 9% of admissions but used 45% of ICU bed-days. After a mean ICU length of stay of 22 days and a subsequent 28 days in hospital, 30% died.

Conclusions

Persistent critical illness is commonly encountered in clinical practice and is associated with increased healthcare utilisation and adverse outcomes. Improvements in our understanding of the longer term outcomes and in the development of tools to aid prognostication are urgently required - for humane as well as health economic reasons.

Daily Oxygenation Support for Patients Hospitalized With SARS-CoV-2 in an Integrated Health System

BACKGROUND

Many COVID-19 studies are constructed to report hospitalization outcomes, with few large multi-center population-based reports on the time course of intra-hospitalization characteristics, including daily oxygenation support requirements. Comprehensive epidemiologic profiles of oxygenation methods used by day and by week during hospitalization across all severities are important to illustrate the clinical and economic burden of COVID-19 hospitalizations.

METHODS

This was a retrospective, multi-center observational cohort study of 15,361 consecutive hospitalizations of patients with COVID-19 at 25 adult acute care hospitals in Texas participating in the Society of Critical Care Medicine Discovery Viral Respiratory Illness Universal Study COVID-19 registry.

RESULTS

At initial hospitalization, the majority required nasal cannula (44.0%), with an increasing proportion of invasive mechanical ventilation in the first week and particularly the weeks to follow. After 4 weeks of acute illness, 69.9% of adults hospitalized with COVID-19 required intermediate (eg, high-flow nasal cannula, noninvasive ventilation) or advanced respiratory support (ie, invasive mechanical ventilation), with similar proportions that extended to hospitalizations that lasted ≥ 6 weeks.

CONCLUSIONS

Data representation of intra-hospital processes of care drawn from hospitals with varied size, teaching and trauma designations is important to presenting a balanced perspective of care delivery mechanisms employed, such as daily oxygen method utilization.

Biological signatures and prediction of an immunosuppressive status-persistent critical illness-among orthopedic trauma patients using machine learning techniques

BACKGROUND

Persistent critical illness (PerCI) is an immunosuppressive status. The underlying pathophysiology driving PerCI remains incompletely understood. The objectives of the study were to identify the biological signature of PerCI development, and to construct a reliable prediction model for patients who had suffered orthopedic trauma using machine learning techniques.

METHODS

This study enrolled 1257 patients from the Medical Information Mart for Intensive Care III (MIMIC-III) database. Lymphocytes were tracked from ICU admission to more than 20 days following admission to examine the dynamic changes over time. Over 40 possible variables were gathered for investigation. Patients were split 80:20 at random into a training cohort (n=1035) and an internal validation cohort (n=222). Four machine learning algorithms, including random forest, gradient boosting machine, decision tree, and support vector machine, and a logistic regression technique were utilized to train and optimize models using data from the training cohort. Patients in the internal validation cohort were used to validate models, and the optimal one was chosen. Patients from two large teaching hospitals were used for external validation (n=113). The key metrics that used to assess the prediction performance of models mainly included discrimination, calibration, and clinical usefulness. To encourage clinical application based on the optimal machine learning-based model, a web-based calculator was developed.

RESULTS

16.0% (201/1257) of all patients had PerCI in the MIMIC-III database. The means of lymphocytes (%) were consistently below the normal reference range across the time among PerCI patients (around 10.0%), whereas in patients without PerCI, the number of lymphocytes continued to increase and began to be in normal range on day 10 following ICU admission. Subgroup analysis demonstrated that patients with PerCI were in a more serious health condition at admission since those patients had worse nutritional status, more electrolyte imbalance and infection-related comorbidities, and more severe illness scores. Eight variables, including albumin, serum calcium, red cell volume distributing width (RDW), blood pH, heart rate, respiratory failure, pneumonia, and the Sepsis-related Organ Failure Assessment (SOFA) score, were significantly associated with PerCI, according to the least absolute shrinkage and selection operator (LASSO) logistic regression model combined with the 10-fold cross-validation. These variables were all included in the modelling. In comparison to other algorithms, the random forest had the optimal prediction ability with the highest area under receiver operating characteristic (AUROC) (0.823, 95% CI: 0.757-0.889), highest Youden index (1.571), and lowest Brier score (0.107). The AUROC in the external validation cohort was also up to 0.800 (95% CI: 0.688-0.912). Based on the risk stratification system, patients in the high-risk group had a 10.0-time greater chance of developing PerCI than those in the low-risk group. A web-based calculator was available at https://starxueshu-perci-prediction-main-9k8eof.streamlitapp.com/.

CONCLUSIONS

Patients with PerCI typically remain in an immunosuppressive status, but those without PerCI gradually regain normal immunity. The dynamic changes of lymphocytes can be a reliable biomarker for PerCI. This work developed a reliable model that may be helpful in improving early diagnosis and targeted intervention of PerCI. Beneficial interventions, such as improving nutritional status and immunity, maintaining electrolyte and acid-base balance, curbing infection, and promoting respiratory recovery, are early warranted to prevent the onset of PerCI, especially among patients in the high-risk group and those with a continuously low level of lymphocytes.

Variation in stroke care at the hospital level: A cross-sectional multicenter study

Introduction

Stroke is one of the leading causes of mortality and disability. Improving patient outcomes can be achieved by improving stroke care and adherence to guidelines. Since wide variation in adherence rates for stroke guidelines still exists, we aimed to describe and compare stroke care variability within Belgian hospitals.

Materials and methods

An observational, multicenter study was performed in 29 Belgian hospitals. We retrospectively collected patient characteristics, quality indicators, and time metrics from the last 30 consecutive patients per hospital, diagnosed with ischemic stroke in 2019 with structured questionnaires. Mean adherence ratios (%) ± SD (minimum – maximum) were calculated.

Results

We analyzed 870 patient records from 29 hospitals. Results showed large inter- and intrahospitals variations in adherence for various indicators. Almost all the patients received brain imaging (99.7%) followed by admission at a stroke unit in 82.9% of patients. Of patients not receiving thrombolysis, 92.5% of patients were started on antithrombotic drugs. Indicators with moderate median adherence but large interhospital variability were glycemia monitoring [82.3 ± 16.7% (26.7–100.0%)], performing clinical neurological examination and documentation of stroke severity [63.1 ± 36.8% (0–100%)], and screening for activities of daily living [51.1 ± 40.3% (0.0–100.0%)]. Other indicators lacked adequate adherence: swallowing function screening [37.0 ± 30.4% (0.0–93.3%)], depression screening [20.2 ± 35.8% (0.0–100%)], and timely body temperature measurement [15.1 ± 17.0% (0.0–60%)].

Conclusion

We identified high adherence to guidelines for some indicators, but lower rates with large interhospital variability for other recommendations also based on robust evidence. Improvement strategies should be implemented to improve the latter.

Postpartum Readmissions for Hypertensive Disorders in Pregnancy During the COVID-19 Pandemic

BACKGROUND

Hypertensive disorders in pregnancy are one of the most common causes of readmission in the postpartum period. Because of the COVID-19 pandemic, early hospital discharge was encouraged for patients who were medically stable, because hospitalization rates among SARS-CoV-2–infected patients steadily increased in 2020. The impact of an early discharge policy on postpartum readmission rates among patients with hypertensive disorders in pregnancy is unknown.

OBJECTIVE

This study aimed to compare the postpartum readmission rates of patients with hypertensive disorders in pregnancy before and after implementation of an early discharge policy owing to the COVID-19 pandemic.

STUDY DESIGN

This was a quality improvement, retrospective cohort study of postpartum patients with antenatal hypertensive disorders in pregnancy who delivered and were readmitted because of hypertensive disorders in pregnancy at the New York University Langone Health medical center from March 1, 2019 to February 29, 2020 (control cohort) and from April 1, 2020 to March 31, 2021 (COVID-19 cohort). During the pandemic, our institution introduced an early discharge policy for all postpartum patients to be discharged no later than 2 days postpartum during the delivery admission if deemed medically appropriate. The reduction in postpartum length of stay was accompanied by the continuation of patient education, home blood pressure monitoring, and outpatient follow-up. The primary outcome was the comparison of the readmission rates for patients with postpartum hypertensive disorders in pregnancy. Data were analyzed using Fisher's Exact tests, chi-square tests, and Wilcoxon rank-sum tests with significance defined as P<.05.

RESULTS

There was no statistical difference in the readmission rates for patients with postpartum hypertensive disorders in pregnancy before vs after implementation of an early discharge policy (1.08% for the control cohort vs 0.59% for the COVID-19 cohort). The demographics in each group were similar, as were the median times to readmission (5.0 days; interquartile range, 4.0–6.0 days vs 6.0 days; interquartile range, 5.0–6.0 days; P=.13) and the median readmission length of stay (3.0 days; interquartile range, 2.0–4.0 days vs 3.0 days; interquartile range, 2.0–4.0 days; P=.45). There was 1 intensive care unit readmission in the COVID-19 cohort and none in the control cohort (P=.35). There were no severe maternal morbidities or maternal deaths.

CONCLUSION

These findings suggest that policies calling for a reduced postpartum length of stay, which includes patients with hypertensive disorders in pregnancy, can be implemented without impacting the hospital readmission rate for patients with hypertensive disorders in pregnancy. Continuation of patient education and outpatient surveillance during the pandemic was instrumental for the outpatient postpartum management of the study cohort. Further investigation into best practices to support early discharges is warranted.

Informing the standardising of care for prolonged stay patients in the ICU: A scoping review of quality improvement tools

OBJECTIVES

To inform design of quality improvement (QI) tools specific to patients with prolonged intensive care unit (ICU) stay, we determined characteristics (format/content), development, implementation, and outcomes of published multi-component QI tools used in ICU irrespective of length of stay.

RESEARCH METHODOLOGY

Scoping review searching electronic databases, trial registries and grey literature (January 2000 to January 2022).

RESULTS

We screened 58,378 citations, identifying 96 studies. All tools were designed for use commencing at ICU admission except 3 tools implemented at 3, 5 or 14 days. We identified 32 studies of locally developed checklists, 28 goal setting/structured communication templates, 23 care bundles, and 9 studies of mixed format tools. Most (43 %) tools were designed for use during rounds, fewer tools were designed for use throughout the ICU day (27 %) or stay (9 %). Most studies (55 %) reported process objectives i.e., improving communication, care standardisation, or rounding efficiency. Most common clinical processes QI tools were used to standardise were sedation (62, 65 %), ventilation and weaning (55, 57 %), and analgesia management (58, 60 %). 44 studies reported the effect of the tool on patient outcomes. Of these, only two identified a negative effect - increased ICU length of stay and increased ICU days with pain and delirium.

CONCLUSION

Although we identified numerous QI tools for use in ICU settings, few were designed to specifically address actionable processes of care relevant to the unique needs of prolonged ICU stay patients. Tools that address these needs are urgently required.

Prevalence, characteristics, and longer-term outcomes of patients with persistent critical illness attributable to COVID-19 in Scotland: a national cohort study

BACKGROUND

Patients with COVID-19 can require critical care for prolonged periods. Patients with persistent critical Illness can have complex recovery trajectories, but this has not been studied for patients with COVID-19. We examined the prevalence, risk factors, and long-term outcomes of critically ill patients with COVID-19 and persistent critical illness.

METHODS

This was a national cohort study of all adults admitted to Scottish critical care units with COVID-19 from March 1, 2020 to September 4, 20. Persistent critical illness was defined as a critical care length of stay (LOS) of ≥10 days. Outcomes included 1-yr mortality and hospital readmission after critical care discharge. Fine and Gray competing risk analysis was used to identify factors associated with persistent critical Illness with death as a competing risk.

RESULTS

A total of 2236 patients with COVID-19 were admitted to critical care; 1045 patients were identified as developing persistent critical Illness, comprising 46.7% of the cohort but using 80.6% of bed-days. Patients with persistent critical illness used more organ support, had longer post-critical care LOS, and longer total hospital LOS. Persistent critical illness was not significantly associated with long-term mortality or hospital readmission. Risk factors associated with increased hazard of persistent critical illness included age, illness severity, organ support on admission, and fewer comorbidities.

CONCLUSIONS

Almost half of all patients with COVID-19 admitted to critical care developed persistent critical illness, with high resource use in critical care and beyond. However, persistent critical illness was not associated with significantly worse long-term outcomes compared with patients who were critically ill for shorter periods.

Defining value in cardiac surgery: A contemporary analysis of cost variation across the United States

Objective

Isolated coronary artery bypass grafting and aortic valve replacement are common cardiac operations performed in the United States and serve as platforms for benchmarking. The present national study characterized hospital-level variation in costs and value for coronary artery bypass grafting and aortic valve replacement.

Methods

Adults undergoing elective, isolated coronary artery bypass grafting or aortic valve replacement were identified in the 2016-2018 Nationwide Readmissions Database. Center quality was defined by the proportion of patients without an adverse outcome (death, stroke, respiratory failure, pneumonia, sepsis, acute kidney injury, and reoperation). High-value hospitals were defined as those with observed-to-expected ratios less than 1 for costs and greater than 1 for quality, whereas the converse defined low-value centers.

Results

Of 318,194 patients meeting study criteria, 71.9% underwent isolated coronary artery bypass grafting and 28.1% underwent aortic valve replacement. Variation in hospital-level costs was evident, with median center-level cost of $36,400 (interquartile range, 29,500-46,700) for isolated coronary artery bypass grafting and $38,400 (interquartile range, 32,300-47,700) for aortic valve replacement. Observed-to-expected ratios for quality ranged from 0.2 to 10.9 for isolated coronary artery bypass grafting and 0.1 to 11.7 for isolated aortic valve replacement. Hospital factors, including volume and quality, contributed to approximately 9.9% and 11.2% of initial cost variation for isolated coronary artery bypass grafting and aortic valve replacement. High-value centers had greater cardiac surgery operative volume and were more commonly teaching hospitals compared to low-value centers, but had similar patient risk profiles.

Conclusions

Significant variation in hospital costs, quality, and value exists for 2 common cardiac operations. Center volume was associated with value and partly accounts for variation in costs. Our findings suggest the need for value-based care paradigms to reduce expenditures and optimize outcomes.

Hospital re-admission after critical care survival: a systematic review and meta-analysis

Survivors of critical illness frequently require increased healthcare resources after hospital discharge. We undertook a systematic review and meta-analysis to assess hospital re-admission rates following critical care admission and to explore potential re-admission risk factors. We searched the MEDLINE, Embase and CINAHL databases on 05 March 2020. Our search strategy incorporated controlled vocabulary and text words for hospital re-admission and critical illness, limited to the English language. Two reviewers independently applied eligibility criteria and assessed quality using the Newcastle Ottawa Score checklist and extracted data. The primary outcome was acute hospital re-admission in the year after critical care discharge. Of the 8851 studies screened, 87 met inclusion criteria and 41 were used within the meta-analysis. The analysis incorporated data from 3,897,597 patients and 741,664 re-admission episodes. Pooled estimates for hospital re-admission after critical illness were 16.9% (95%CI: 13.3-21.2%) at 30 days; 31.0% (95%CI: 24.3-38.6%) at 90 days; 29.6% (95%CI: 24.5-35.2%) at six months; and 53.3% (95%CI: 44.4-62.0%) at 12 months. Significant heterogeneity was observed across included studies. Three risk factors were associated with excess acute care rehospitalisation one year after discharge: the presence of comorbidities; events during initial hospitalisation (e.g. the presence of delirium and duration of mechanical ventilation); and subsequent infection after hospital discharge. Hospital re-admission is common in survivors of critical illness. Careful attention to the management of pre-existing comorbidities during transitions of care may help reduce healthcare utilisation after critical care discharge. Future research should determine if targeted interventions for at-risk critical care survivors can reduce the risk of subsequent rehospitalisation.

Impact of frailty on persistent critical illness: a population-based cohort study

PURPOSE

Acute illness severity predicts mortality in intensive care unit (ICU) patients, however, its predictive value decreases over time in ICU. Typically after 10 days, pre-ICU (antecedent) characteristics become more predictive of mortality, defining the onset of persistent critical illness (PerCI). How patient frailty affects development and death from PerCI is unknown.

METHODS

We conducted a secondary analysis of data from a prospective binational cohort study including 269,785 critically ill adults from 168 ICUs in Australia and New Zealand, investigating whether frailty measured with the Clinical Frailty Scale (CFS) changes the timing of onset and risk of developing PerCI and of subsequent in-hospital mortality. We assessed associations between frailty (CFS ≥ 5) and mortality prediction using logistic regression and area under the receiver operating characteristics (AUROC) curves.

RESULTS

2190 of 50,814 (4.3%) patients with frailty (CFS ≥ 5) versus 6624 of 218,971 (3%) patients without frailty (CFS ≤ 4) developed PerCI (P < 0.001). Among patients with PerCI, 669 of 2190 (30.5%) with frailty and 1194 of 6624 without frailty (18%) died in hospital (P < 0.001). The time point defining PerCI onset did not vary with frailty degree; however, with increasing length of ICU stay, inclusion of frailty progressively improved mortality discrimination (0.1% AUROC improvement on ICU day one versus 3.6% on ICU day 17).

CONCLUSION

Compared to patients without frailty, those with frailty have a higher chance of developing and dying from PerCI. Moreover the importance of frailty as a predictor of mortality increases with ICU length of stay. Future work should explore incorporation of frailty in prognostic models, particularly for long-staying patients.

Prognostication in neurology

Prognosticating is central to primary palliative care in neurology. Many neurologic diseases carry a high burden of troubling symptoms, and many individuals consider health states due to neurologic disease worse than death. Many patients and families report high levels of need for information at all disease stages, including information about prognosis. There are many barriers to communicating prognosis including prognostic uncertainty, lack of training and experience, fear of destroying hope, and not enough time. Developing the right mindset, tools, and skills can improve one's ability to formulate and communicate prognosis. Prognosticating is subject to many biases which can dramatically affect the quality of patient care; it is important for providers to recognize and reduce them. Patients and surrogates often do not hear what they are told, and even when they hear correctly, they form their own opinions. With practice and self-reflection, one can improve their prognostic skills, help patients and families create honest roadmaps of the future, and deliver high-quality person-centered care.

Insights into the challenges faced by chronically critically ill patients, their families and healthcare providers: An interpretive description

OBJECTIVE

To describe and understand the challenges of patients with chronic critical illness (CCI), their families and healthcare providers during the disease trajectory.

METHODOLOGY/DESIGN

This qualitative study follows Thorne's methodology of interpretive description and was guided by the ethnographic method of observation and participation. Five cases, each comprising one patient with chronic critical illness their family members and several healthcare providers, were followed from the intensive care unit of a university hospital in Switzerland across different settings. In total, five patients with chronic critical illness, 12 family members and 92 healthcare providers (nurses, nursing students, care assistants, physiotherapists and occupational therapists and physicians) were observed.

FINDINGS

Regardless of the medical diagnoses and disease trajectories of the patients with chronic critical illness, all cases faced three main challenges: 1. Dealing with the unpredictability of the disease trajectory beyond the underlying disease. 2. Coping with the complexity of care. 3. Perceiving communication challenges despite all involved parties' dependency on it.

CONCLUSION

Unpredictability is not only a unique characteristic of the prolonged disease trajectory of patients with chronic critical illness, but also one of the main challenges of the participants. Therefore, the way unpredictability is handled is dependent on changes in the complexity of care and communication, highlighting the need for participation, information, empathy, clarity and honesty among all participants.

Actionable processes of care important to patients and family who experienced a prolonged intensive care unit stay: Qualitative interview study

AIM

To use positive deviance to identify actionable processes of care that may improve outcomes and experience from the perspectives of prolonged intensive care unit (ICU) stay survivors and family members.

DESIGN

Prospective qualitative interview study in two geographically distant settings: Canada (2018/19) and the United Kingdom (2019/20).

METHODS

Patient and family participant inclusion criteria comprised: aged over 18 years, ICU stay in last 2 years of over 7 days, able to recall ICU stay and provided informed consent. We conducted semi-structured in-person or telephone interviews. Data were analysed using a positive deviance approach.

RESULTS

We recruited 29 participants (15 Canadian; 14 UK). Of these, 11 were survivors of prolonged ICU stay and 18 family members. We identified 22 actionable processes (16 common to Canadian and UK participants, 4 Canadian only and 2 UK only). We grouped processes under three themes: physical and functional recovery (nine processes), patient psychological well-being (seven processes) and family relations (six processes). Most commonly identified physical/functional processes were regular physiotherapy, and fundamental hygiene and elimination care. For patient psychological well-being: normalizing the environment and routines, and alleviating boredom and loneliness. For family relations: proactive communication, flexible family visiting and presence with facilities for family. Our positive deviance analysis approach revealed that incorporation of these actionable processes into clinical practice was the exception as opposed to the norm perceived driven by individual acts of kindness and empathy as opposed to standardized processes.

CONCLUSION

Actionable processes of care important to prolonged ICU stay survivors and family members differ from those frequently used in ICU quality improvement (QI) tools.

IMPACT

Our study emphasizes the need to develop QI tools that standardize delivery of actionable processes important to patients and families experiencing a prolonged ICU stay. As the largest healthcare professional group, nurses can play an essential role in leading this.
