Value in Acute Care Surgery, Part 3: Defining Value in Acute Surgical Care - It Depends on the Perspective

ABSTRACT

The prior articles in this series have focused on measuring cost and quality in acute care surgery. This third article in the series explains the current ways of defining value in acute care surgery, based on different stakeholders in the healthcare system - the patient, the healthcare organization, the payer and society. The heterogenous valuations of the different stakeholders require that the framework for determining high-value care in acute care surgery incorporates all viewpoints.

Management of Uncomplicated Appendicitis in Adults: A Nationwide Analysis From 2018 to 2019

INTRODUCTION

Nonoperative management (NOM) of uncomplicated appendicitis (UA) has been increasingly utilized in recent years. The aim of this study was to describe nationwide trends of sociodemographic characteristics, outcomes, and costs of patients undergoing medical versus surgical management for UA.

METHODS

The 2018-2019 National (Nationwide) Inpatient Sample was queried for adults (age ≥18 y) with UA; diagnosis, as well as laparoscopic and open appendectomy, were defined by the International Classification of Diseases, 10th Revision, Clinical Modification codes. We examined several characteristics, including cost of care and length of hospital stay.

RESULTS

Among the 167,125 patients with UA, 137,644 (82.4%) underwent operative management and 29,481 (17.6%) underwent NOM. In bivariate analysis, we found that patients who had NOM were older (53 versus 43 y, P < 0.001) and more likely to have Medicare (33.6% versus 16.1%, P < 0.001), with higher prevalence of comorbidities such as diabetes (7.8% versus 5.5%, P < 0.001). The majority of NOM patients were treated at urban teaching hospitals (74.5% versus 66.3%, P < 0.001). They had longer LOS's (5.4 versus 2.3 d, P < 0.001) with higher inpatient costs ($15,584 versus $11,559, P < 0.001) than those who had an appendectomy. Through logistic regression we found that older patients had up to 4.03-times greater odds of undergoing NOM (95% CI: 3.22-5.05, P < 0.001).

CONCLUSIONS

NOM of UA is more commonly utilized in patients with comorbidities, older age, and those treated in teaching hospitals. This may, however, come at the price of longer length of stay and higher costs. Further guidelines need to be developed to clearly delineate which patients could benefit from NOM.

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters

INTRODUCTION

There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs).

METHODS

We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes. Within this sample, we analyzed characteristics and outcomes of patients with firearm-related injuries. The primary outcome was mortality; secondary outcomes were ED charges and length of stay.

RESULTS

Among the 25.2 million substance use disorder (SUD) patients in our analysis, 35,306 (0.14%) had a firearm-related diagnosis. Compared to other SUD patients, firearm-SUD patients were younger (33.3 versus 44.7 years, P < 0.001), primarily male (88.6% versus 54.2%, P < 0.001), of lower-income status (0-25th percentile income: 56.4% versus 40.5%, P < 0.001), and more likely to be insured by Medicaid or self-pay (71.6% versus 53.2%, P < 0.001). Firearm-SUD patients had higher mortality (1.4% versus 0.4%, P < 0.001), longer lengths of stay (6.5 versus 4.9 days, P < 0.001), and higher ED charges ($9269 versus $5,164, P < 0.001). Firearm-SUD patients had a 60.3% rate of psychiatric diagnoses. Firearm-SUD patients had 5.5 times greater odds of mortality in adjusted analyses (adjusted odds ratio: 5.5, P < 0.001).

CONCLUSIONS

Opioid-substance abuse patients with firearm injuries have higher mortality rates and costs among these groups, with limited discharge to postacute care resources. All these factors together point to the urgent need for improved screening and treatment for this vulnerable group of patients.

A Qualitative Study of Emergency Medicaid Programs From the Perspective of Hospital Stakeholders

INTRODUCTION

Uninsured patients often have poor clinical outcomes associated with lower access to care. Hospital Presumptive Eligibility (HPE) provides up to 60-d emergency Medicaid coverage for uninsured, low-income patients. After obtaining 60-d HPE, patients must file for ongoing Medicaid to sustain coverage; however, navigating HPE approval is complex. We conducted a qualitative study to understand (1) stakeholder perspectives on the application process and workflow and (2) facilitators and barriers to HPE approval to understand process improvement opportunities.

MATERIAL AND METHODS

We conducted semi-structured interviews between September-December 2021 with key stakeholders (social workers, financial counselors, case managers, and private third-party vendor representatives) involved in HPE coverage determination, screening, approval, and Medicaid sustainment at our institution. We performed a team-based thematic analysis to elicit factors influencing HPE screening and approval, and recommendations for process improvement.

RESULTS

Study participants described the HPE application and Medicaid approval processes. Patient-level barriers included information disclosure and immigration status, inability to contact patients or next-of-kin, and knowledge gaps about insurance acquisition and sustainment. System-level barriers included technical challenges with the state HPE application portal, inadequate staffing for patient screening, and short emergency department stays that limited opportunities to initiate HPE. Stakeholders proposed improvements in education, patient outreach, and logistics.

CONCLUSIONS

This qualitative study reveals the process of HPE approval and outlines barriers within HPE and Medicaid processing from the perspective of direct hospital stakeholders. We identified opportunities at the patient, hospital, and policy levels that could improve successful HPE application and approval rates.

Delayed hollow viscus injury with an occult seatbelt abrasion presenting as a small bowel obstruction

We present the case of a previously healthy 29-year-old male who presented with a small bowel obstruction in the absence of previous abdominal surgery who was found to have evidence of an occult seatbeltabrasion and ultimately multifocal hollow viscus injury secondary to blunt abdominal trauma at the time of exploratory laparotomy. Hollow viscus injury is a rare, but potentially life-threatening, complication of blunt abdominal trauma. While cross-sectional imaging is an important diagnostic tool, results must be considered within a patient's clinical context as delays in surgical management can lead to significant morbidity and mortality.

Glasgow Coma Scale Intubation Thresholds and Outcomes of Patients With Traumatic Brain Injury: The Need for Tailored Practice Management Guidelines

INTRODUCTION

This study aims to re-evaluate the GCS threshold for intubation in patients presenting to the ED with a traumatic brain injury to optimize outcomes and provide evidence for future practice management guidelines.

METHODS

We retrospectively reviewed the ACS-TQIP-Participant Use File (PUF) 2015-2019 for adult trauma patients 18 years and older who experienced a blunt traumatic head injury and received computerized tomography. Multivariable regressions were performed to assess associations between outcomes and GCS intubation thresholds of 5, 8, and 10.

RESULTS

In patients with a GCS ≤5, there were no differences in mortality (GCS ≤5: 26.3% vs GCS >5: 28.3%, adjusted P = .08), complication rates (GCS ≤5: 9.1% vs GCS >5: 10.3%, adjusted P = .91), or ICU length of stay (GCS ≤5: 5.4 vs GCS >5: 4.7, adjusted P = .36) between intubated and non-intubated patients. Intubated patients at GCS thresholds ≤8 (26.2% vs 19.1%, adjusted P < .0001) and ≤10 (25.6% vs 15.8%, adjusted P < .0001) had significantly higher mortality rates than non-intubated patients. Intubation at all GCS thresholds >5 resulted in higher rates of complications, H-LOS, and ICU-LOS when compared to non-intubated patients with the same GCS score.

CONCLUSION

A GCS ≤5 was the threshold at which intubation in TBI patients conferred an additional benefit in disposition without worsened outcomes of mortality, H-LOS, or ICU-LOS. Trauma societies and hospital institutions should consider revisiting existing guidelines and protocols concerning the appropriate GCS threshold for safer intubation and better outcomes among these patient population.

Trends in disparities research on trauma and acute care surgery outcomes: A 10-year systematic review of articles published in The Journal of Trauma and Acute Care Surgery

ABSTRACT

This is a 10-year review of The Journal of Trauma and Acute Care Surgery (JTACS) literature related to health care disparities, health care inequities, and patient outcomes. A retrospective review of articles published in JTACS between January 1, 2013, and July 15, 2022, was performed. Articles screened included both adult and pediatric trauma populations. Included articles focused on patient populations related to trauma, surgical critical care, and emergency general surgery. Of the 4,178 articles reviewed, 74 met the inclusion criteria. Health care disparities related to gender (n = 10), race/ethnicity (n = 12), age (n = 14), income status (n = 6), health literacy (n = 6), location and access to care (n = 23), and insurance status (n = 13) were described. Studies published on disparities peaked in 2016 and 2022 with 13 and 15 studies respectively but dropped to one study in 2017. Studies demonstrated a significant increase in mortality for patients in rural geographical regions and in patients without health insurance and a decrease in patients who were treated at a trauma center. Gender disparities resulted in variable mortality rates and studied factors, including traumatic brain injury mortality and severity, venous thromboembolism, ventilator-associated pneumonia, firearm homicide, and intimate partner violence. Under-represented race/ethnicity was associated with variable mortality rates, with one study demonstrating increased mortality risk and three finding no association between race/ethnicity and mortality. Disparities in health literacy resulted in decreased discharge compliance and worse long-term functional outcomes. Studies on disparities in JTACS over the last decade primarily focused on location and access to health care, age, insurance status, and race, with a specific emphasis on mortality. This review highlights the areas in need of further research and funding in the Journal of Trauma and Acute Care Surgery regarding health care disparities in trauma aimed at interventions to reduce disparities in patient care, ensure equitable care, and inform future approaches targeting health care disparities.

An Open-Source Curriculum to Teach Practical Academic Research Skills

Academic productivity is important for career advancement, yet not all trainees have access to structured research programs. Without formal teaching, acquiring practical skills for research can be challenging. A comprehensive research course that teaches practical skills to translate ideas into publications could accelerate trainees' productivity and liberate faculty mentors' time. We share our experience designing and teaching "A Practical Introduction to Academic Research", a course that teaches practical skills including building productive habits, recognizing common statistical pitfalls, writing cover letters, succinct manuscripts, responding to reviewers, and delivering effective presentations. We share open-source educational material used during the Winter 2022 iteration to facilitate curriculum adoption at peer institutions.

Bias in the trauma bay: A multicenter qualitative study on team communication

BACKGROUND

Team communication and bias in and out of the operating room have been shown to impact patient outcomes. Limited data exist regarding the impact of communication bias during trauma resuscitation and multidisciplinary team performance on patient outcomes. We sought to characterize bias in communication among health care clinicians during trauma resuscitations.

METHODS

Participation from multidisciplinary trauma team members (emergency medicine and surgery faculty, residents, nurses, medical students, emergency medical services personnel) was solicited from verified level 1 trauma centers. Comprehensive semistructured interviews were conducted and recorded for analysis; sample size was determined by saturation. Interviews were led by a team of doctorate communications experts. Central themes regarding bias were identified using Leximancer analytic software (Leximancer Pty Ltd., Brisbane, Australia).

RESULTS

Interviews with 40 team members (54% female, 82% White) from 5 geographically diverse Level 1 trauma centers were conducted. More than 14,000 words were analyzed. Statements regarding bias were analyzed and revealed a consensus that multiple forms of communication bias are present in the trauma bay. The presence of bias is primarily related to sex but was also influenced by race, experience, and occasionally the leader's age, weight, and height. The most commonly described targets of bias were females and non-White providers unfamiliar to the rest of the trauma team. Most common sources of bias were White male surgeons, female nurses, and nonhospital staff. Participants perceived bias being unconscious but affecting patient care.

CONCLUSION

Bias in the trauma bay is a barrier to effective team communication. Identification of common targets and sources of biases may lead to more effective communication and workflow in the trauma bay.

Insurance churn after adult traumatic injury: A national evaluation among a large private insurance database

BACKGROUND

Traumatic injury leads to significant disability, with injured patients often requiring substantial health care resources to return to work and baseline health. Temporary disability or inability to work can result in changes or loss of employer-based private insurance coverage, which may significantly impact health care access and outcomes. Among privately insured patients, we hypothesized increased instability in insurance coverage for patients with higher severity of injury.

METHODS

Adults 18 years and older presenting to a hospital with traumatic injury were evaluated for insurance churn using Clinformatics Data Mart private-payer claims. Insurance churn was defined as cessation of enrollment in the patient's private health insurance plan. Using Injury Severity Score (ISS), we compared insurance churn over the year following injury between patients with mild (ISS, <9), moderate (ISS, 9-15), severe (ISS, 16-24), and very severe (ISS, >24) injuries. Kaplan-Meier analysis was used to compare time with insurance churn by ISS category. Flexible parametric regression was used to estimate hazard ratios for insurance churn.

RESULTS

Among 750,862 privately insured patients suffering from a traumatic injury, 50% experienced insurance churn within 1 year after injury. Compared with patients who remained on their insurance plan, patients who experienced insurance churn were younger and more likely male and non-White. The median time to insurance churn was 7.7 months for those with mild traumatic injury, 7.5 months for moderately or severely injured, and 7.1 months for the very severely injured. In multivariable analysis, increasing injury severity was associated with higher rates of insurance churn compared with mild injury, up to 14% increased risk for the very severely injured.

CONCLUSION

Increasing severity of traumatic injury is associated with higher levels of health coverage churn among the privately insured. Lack of continuous access to health services may prolong recovery and further aggravate the medical and social impact of significant traumatic injury.

Non-surgical management and analgesia strategies for older adults with multiple rib fractures: A systematic review, meta-analysis, and joint practice management guideline from the Eastern Association for the Surgery of Trauma and the Chest Wall Injury Society

BACKGROUND

Chest wall injury in older adults is a significant cause of morbidity and mortality. Optimal nonsurgical management strategies for these patients have not been fully defined regarding level of care, incentive spirometry (IS), noninvasive positive pressure ventilation (NIPPV), and the use of ketamine, epidural, and other locoregional approaches to analgesia.

METHODS

Relevant questions regarding older patients with significant chest wall injury with patient population(s), intervention(s), comparison(s), and appropriate selected outcomes were chosen. These focused on intensive care unit (ICU) admission, IS, NIPPV, and analgesia including ketamine, epidural analgesia, and locoregional nerve blocks. A systematic literature search and review were conducted, our data were analyzed qualitatively and quantitatively, and the quality of evidence was assessed per the Grading of Recommendations Assessment, Development, and Evaluation methodology. No funding was used.

RESULTS

Our literature review (PROSPERO 2020-CRD42020201241, MEDLINE, EMBASE, Cochrane, Web of Science, January 15, 2020) resulted in 151 studies. Intensive care unit admission was qualitatively not superior for any defined cohort other than by clinical assessment. Poor IS performance was associated with prolonged hospital length of stay, pulmonary complications, and unplanned ICU admission. Noninvasive positive pressure ventilation was associated with 85% reduction in odds of pneumonia ( p < 0.0001) and 81% reduction in odds of mortality ( p = 0.03) in suitable patients without risk of airway loss. Ketamine use demonstrated no significant reduction in pain score but a trend toward reduced opioid use. Epidural and other locoregional analgesia techniques did not affect pneumonia, length of mechanical ventilation, hospital length of stay, or mortality.

CONCLUSION

We do not recommend for or against routine ICU admission. We recommend use of IS to inform ICU status and conditionally recommend use of NIPPV in patients without risk of airway loss. We offer no recommendation for or against ketamine, epidural, or other locoregional analgesia.

Developing an Inpatient Relationship Centered Communication Curriculum (I-RCCC) rounding framework for surgical teams

BACKGROUND

Morning rounds by an acute care surgery (ACS) service at a level one trauma center are uniquely demanding, given the fast pace, high acuity, and increased patient volume. These demands notwithstanding, communication remains integral to the success of surgical teams. Yet there are limited published curricula that address trauma inpatient communication needs. Observations at our institution confirmed that the surgical team lacked a shared mental model for communication. We hypothesized that creating a relationship-centered rounding conceptual framework model would enhance the provider-patient experience.

STUDY DESIGN

A mixed-methods approach was used for this study. A multi-pronged needs assessment was conducted. Provider communion items for Press Ganey and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys were used to measure patients' expressed needs. Faculty with experience in relationship-centered communication observed morning rounds and documented demonstrated behaviors. A five-hour workshop was designed based on the identified needs. A pre-and post-course Assessment and course evaluation were conducted. Provider-related patient satisfaction items were measured six months before the course and six months after the workshop.

RESULTS

Needs assessment revealed a lack of a shared communication framework and a lack of leadership skills for senior trauma residents. Barriers included: time constraints, patient load, and interruptions during rounds. The curriculum was very well received. The self-reflected behaviors that demonstrated the most dramatic change between the pre and post-workshop surveys were: I listened without interrupting; I spoke clearly and at a moderate pace; I repeated key points; and I checked that the patient understood. All these changed from being performed by 50% of respondents "about half of the time" to 100% of them "always". Press Ganey top box likelihood to recommend (LTR) and provider-related top box items showed a trend towards improvement after implementing the training with a percentage difference of up to 20%.

CONCLUSION

The Inpatient Relationship Centered Communication Curriculum (I-RCCC) targeting senior residents and Nurse Practitioners (NP) was feasible, practical, and well-received by participants. There was a trend of an increase in LTRs and provider-specific patient satisfaction items. This curriculum will be refined based on the study results and potentially scalable to other surgical specialties.

Quality care is equitable care: a call to action to link quality to achieving health equity within acute care surgery

Health equity is defined as the sixth domain of healthcare quality. Understanding health disparities in acute care surgery (defined as trauma surgery, emergency general surgery and surgical critical care) is key to identifying targets that will improve outcomes and ensure delivery of high-quality care within healthcare organizations. Implementing a health equity framework within institutions such that local acute care surgeons can ensure equity is a component of quality is imperative. Recognizing this need, the AAST (American Association for the Surgery of Trauma) Diversity, Equity and Inclusion Committee convened an expert panel entitled 'Quality Care is Equitable Care' at the 81st annual meeting in September 2022 (Chicago, Illinois). Recommendations for introducing health equity metrics within health systems include: (1) capturing patient outcome data including patient experience data by race, ethnicity, language, sexual orientation, and gender identity; (2) ensuring cultural competency (eg, availability of language services; identifying sources of bias or inequities); (3) prioritizing health literacy; and (4) measuring disease-specific disparities such that targeted interventions are developed and implemented. A stepwise approach is outlined to include health equity as an organizational quality indicator.

Building a Trainee-led Research Community to Propel Academic Productivity in Health Services Research

Academic productivity is an increasingly important asset for trainees pursuing academic careers. Medical schools and graduate medical education programs offer structured research programs, but providing longitudinal and individualized health services research education remains challenging. Whereas in basic science research, members at multiple training levels support each other within a dedicated community (the laboratory), health services research projects frequently occur within individual faculty-trainee relationships. An optimal match of expertise, availability, and interest may be elusive for an individual mentor-mentee pair. We aimed to share our experience building Surgeons Writing about Trauma (SWAT), a trainee-led research community that propels academic productivity by facilitating peer collaboration and opportunities to transition into independent researchers. We highlight challenges of health services research for trainees, present how structured mentorship and a peer community can address this challenge, and detail SWAT's operational structure to guide replication at peer institutions.

Introducing advanced surgical tasks simulation for surgical training

Acquiring surgical skills is one of the major objectives of surgical training. Trainees face increasing challenges to meet the continuously evolving surgical techniques and approaches during the limited time course of their surgical training. The limited availability of training tools for teaching advanced surgical skills is an additional barrier. Educators have increasingly used simulation tools for surgical skills training around the globe. However, current simulation training modules and curricula focus mainly on basic surgical skills. Hence, the development of advanced virtual simulation modules offers a precious laparoscopic training opportunity. This article provides an educational technology-based review and proposal (with selected examples) of simulation training modules on advanced surgical skills that can be used for advanced surgical training approaches.

Challenging Traditional Paradigms in Posttraumatic Pulmonary Thromboembolism

Importance

Pulmonary clots are seen frequently on chest computed tomography performed after trauma, but recent studies suggest that pulmonary thrombosis (PT) and pulmonary embolism (PE) after trauma are independent clinical events.

Objective

To assess whether posttraumatic PT represents a distinct clinical entity associated with the nature of the injury, different from the traditional venous thromboembolic paradigm of deep venous thrombosis (DVT) and PE.

Design, Setting, and Participants

This prospective, observational, multicenter cohort study was conducted by the Consortium of Leaders in the Study of Traumatic Thromboembolism (CLOTT) study group. The study was conducted at 17 US level I trauma centers during a 2-year period (January 1, 2018, to December 31, 2020). Consecutive patients 18 to 40 years of age admitted for a minimum of 48 hours with at least 1 previously defined trauma-associated venous thromboembolism (VTE) risk factor were followed up until discharge or 30 days.

Exposures

Investigational imaging, prophylactic measures used, and treatment of clots.

Main Outcomes and Measures

The main outcomes of interest were the presence, timing, location, and treatment of any pulmonary clots, as well as the associated injury-related risk factors. Secondary outcomes included DVT. We regarded pulmonary clots with DVT as PE and those without DVT as de novo PT.

Results

A total of 7880 patients (mean [SD] age, 29.1 [6.4] years; 5859 [74.4%] male) were studied, 277 with DVT (3.5%), 40 with PE (0.5%), and 117 with PT (1.5%). Shock on admission was present in only 460 patients (6.2%) who had no DVT, PT, or PE but was documented in 11 (27.5%) of those with PE and 30 (25.6%) in those with PT. Risk factors independently associated with PT but not DVT or PE included shock on admission (systolic blood pressure <90 mm Hg) (odds ratio, 2.74; 95% CI, 1.72-4.39; P < .001) and major chest injury with Abbreviated Injury Score of 3 or higher (odds ratio, 1.72; 95% CI, 1.16-2.56; P = .007). Factors associated with the presence of PT on admission included major chest injury (14 patients [50.0%] with or without major chest injury with an Abbreviated Injury Score >3; P = .04) and major venous injury (23 [82.1%] without major venous injury and 5 [17.9%] with major venous injury; P = .02). No deaths were attributed to PT or PE.

Conclusions and Relevance

To our knowledge, this CLOTT study is the largest prospective investigation in the world that focuses on posttraumatic PT. The study suggests that most pulmonary clots are not embolic but rather result from inflammation, endothelial injury, and the hypercoagulable state caused by the injury itself.

Out-of-Pocket Costs Among Patients With a New Cancer Diagnosis Enrolled in High-Deductible Health Plans vs Traditional Insurance

IMPORTANCE

The financial burden of a cancer diagnosis is increasing rapidly with advances in cancer care. Simultaneously, more individuals are enrolling in high-deductible health plans (HDHPs) vs traditional insurance than ever before.

OBJECTIVE

To characterize the out-of-pocket costs (OOPCs) of cancer care for individuals in HDHPs vs traditional insurance plans.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used the administrative claims data of a single national insurer in the US for 134 826 patients aged 18 to 63 years with a new diagnosis of breast, colorectal, lung, or other cancer from 2008 to 2018 with 24 months or more of continuous enrollment. Propensity score matching was performed to create comparator groups based on the presence or absence of an incident cancer diagnosis.

EXPOSURES

A new cancer diagnosis and enrollment in an HDHP vs a traditional health insurance plan.

MAIN OUTCOMES AND MEASURES

The primary outcome was OOPCs among individuals with breast, colon, lung, or all other types of cancer combined compared with those with no cancer diagnosis. A triple difference-in-differences analysis was performed to identify incremental OOPCs based on cancer diagnosis and enrollment in HDHPs vs traditional plans.

RESULTS

After propensity score matching, 134 826 patients remained in each of the cancer (73 572 women [55%]; median age, 53 years [IQR, 46-58 years]; 110 071 non-Hispanic White individuals [82%]) and noncancer (66 619 women [49%]; median age, 53 years [IQR, 46-59 years]; 105 023 non-Hispanic White individuals [78%]) cohorts. Compared with baseline costs of medical care among individuals without cancer, a breast cancer diagnosis was associated with the highest incremental OOPC ($714.68; 95% CI, $664.91-$764.45), followed by lung ($475.51; 95% CI, $340.16-$610.86), colorectal ($361.41; 95% CI, $294.34-$428.48), and all other types of cancer combined ($90.51; 95% CI, $74.22-$106.79). Based on the triple difference-in-differences analysis, compared with patients without cancer enrolled in HDHPs, those with breast cancer paid $1683.36 in additional yearly OOPCs (95% CI, $1576.66-$1790.07), those with colorectal cancer paid $1420.06 more (95% CI, $1232.31-$1607.80), those with lung cancer paid $467.25 more (95% CI, $130.13-$804.37), and those with other types of cancer paid $550.87 more (95% CI, $514.75-$586.99).

CONCLUSIONS AND RELEVANCE

Patients with cancer and private insurance experienced sharp increases in OOPCs compared with those without cancer, which was amplified among those with HDHPs. These findings illustrate the degree to which HDHPs offer poorer protection than traditional insurance against unexpected health care expenses. Coupled with the increasing cost of cancer care, higher cost sharing in the form of increasing enrollment in HDHPs requires further research on the potential clinical consequences through delayed or foregone care.

Virtual reality (VR) as a simulation modality for technical skills acquisition

Efforts continue to facilitate surgical skills training and provide accessible and safe training opportunities. Educational technology has played an essential role in minimizing the challenges facing traditional surgical training and providing feasible training opportunities. Simulation and virtual reality (VR) offer an important innovative training approach to enhance and supplement both technical and non-technical skills acquisition and overcome the many training challenges facing surgical training programs. To maximize the effectiveness of simulation modalities, an in-depth understanding of the cognitive learning theory is necessary. Knowing the stages and mental processes of skills acquisition when integrated with simulation applications can help trainees achieve maximal learning outcomes. This article aims to review important literature related to VR effectiveness and discuss the leading theories of technical skills acquisition related to VR simulation technologies.

Mortality After General Surgery Among Hospitalized Patients With Hematologic Malignancy

BACKGROUND

Hospitalized patients with hematologic malignancies (HMs) may require abdominal operations for complications of malignancy, treatment sequelae, or unrelated abdominal pathology. We determined predictors of mortality after emergency general surgery for patients with HM using national-level data.

MATERIALS AND METHODS

We analyzed the 2010-2014 National Inpatient Sample for International Classification of Disease, Ninth Revision, Clinical Modification codes for HM and abdominal operations, comparing adult patient encounters with abdominal operations with HM to those without HM. Multivariate logistic regression was performed to identify predictors of mortality.

RESULTS

Of the 7.9 million adult inpatient encounters where abdominal surgery was performed, 82,187 (1%) had concomitant diagnoses of HM. Mortality among patient encounters with HM was significantly higher than without HM (9.0% versus 2.0%; P < 0.0001). Patient encounters with HM and surgery and a diagnosis of acute abdominal pain had mortality rates as high as 41%. The median standardized risk ratio for death after the top 25 general surgery procedures was 2.9 (interquartile range: 2.2-3.8) among patients with HM. In adjusted analyses, odds of mortality among patients with HM undergoing surgery were increased by concomitant acute abdominal pain diagnosis (odds ratio [OR] = 2.6; P < 0.0001), coagulopathy (OR = 2.0; P < 0.0001), aplastic anemia (OR = 1.7; P < 0.0001), peripheral vascular disease (OR = 1.4; P = 0.001), and weight loss (OR = 1.3; P < 0.0001).

CONCLUSIONS

Although uncommon, surgery on patients with HM is associated with mortality rates nearly five times higher than the general surgical population. Patients with HM requiring surgical intervention may be at particularly high odds of death and postoperative complications.

Understanding Health Care Utilization and Mortality After Emergency General Surgery in Patients With Underlying Liver Disease

BACKGROUND

Mortality and complications are not well defined nationally for emergency general surgery (EGS) patients presenting with underlying all-cause liver disease (LD).

STUDY DESIGN

We analyzed the 2012-2014 National Inpatient Sample for adults (aged ≥ 18 years) with a primary EGS diagnosis. Underlying LD included International Classification of Diseases, Ninth Revision, Clinical Modification codes for alcoholic and viral hepatitis, malignancy, congenital etiologies, and cirrhosis. The primary outcome was mortality; secondary outcomes included complications, operative intervention, and costs.

RESULTS

Of the 6.8 million EGS patients, 358 766 (5.3%) had underlying LD. 59.1% had cirrhosis, 6.7% had portal hypertension, and 13.7% had ascites. Compared with other EGS patients, EGS-LD patients had higher mean costs ($12 847 vs $10 234, P < .001). EGS-LD patients were less likely to have surgery (26.1% vs 37.0%, P < .001) but for those who did, mortality was higher (4.8% vs 1.8%, P < .001). Risk factors for mortality included ascites (adjusted odds ratio [aOR] = 2.68, P < .001), dialysis (aOR = 3.44, P < .001), sepsis (aOR = 8.97, P < .001), and respiratory failure requiring intubation (aOR = 10.40, P < .001). Odds of death increased in both surgical (aOR = 4.93, P < .001) and non-surgical EGS-LD patients (aOR = 2.56, P < .001).

CONCLUSIONS

Underlying all-cause LD among EGS patients is associated with increased in-hospital mortality, even in the absence of surgical intervention.

Traumatic Injuries Due to Interpersonal and Domestic Violence in the United States

BACKGROUND

Domestic and intimate partner violence (DV) are under-reported causes of injury. We describe the health care utilization of DV patients, hypothesizing they are at increased risk of mortality.

METHODS

We queried the 2014 Nationwide Emergency Department Sample for adult patients (18 y and older) with a primary diagnosis of trauma. DV was abstracted using International Statistical Classification of Diseases, ninth Revision codes for partner or spouse intimate violence, abuse, or neglect. The primary outcome was mortality; secondary outcomes included admission rates and charges.

RESULTS

Among 14 million trauma patients, 654,356 (5.0%) had a diagnosis of DV. Compared with other trauma patients, DV patients were younger (34.6 versus 46.8 y, P < 0.001), more often male (69.5% versus 50.1%, P < 0.001), and more likely to be uninsured (31.5% versus 15.6%, P < 0.001). 9154 (1.4%) were injured because of intimate partner violence, of which 90.2% were female. Drug and alcohol abuse (22.2%), anxiety (1.8%), and depression (1.3%) were high among all DV trauma patients. DV emergency department charges were higher ($4462 versus $2,871, P < 0.001). In adjusted analyses, DV trauma patients had 2.1 higher odds of mortality (aOR: 2.31, P < 0.001). DV trauma patients were also associated with a $1516 increase in emergency department charges compared with non-DV trauma patients (95% CI: $1489-$1,542, P < 0.001).

CONCLUSIONS

Injuries related to all types of DV are emerging as a public health crisis among both genders. To mitigate under-reporting, it is important to identify at-risk patients and provide them with appropriate resources.

Impact of shelter-in-place order for COVID-19 on trauma activations: Santa Clara County, California, March 2020

Introduction

The shelter-in-place order for Santa Clara County, California on 16 March was the first of its kind in the USA. It was unknown what impact this order would have on trauma activations.

Methods

We performed a retrospective analysis of institutional trauma registries among the two American College of Surgeons Level 1 trauma centers serving Santa Clara County, California. Trauma activation volumes at the trauma centers from January to March 2020 were compared with month-matched historical cohorts from 2018 to 2019.

Results

Only 81 (3%) patients were trauma activations at the trauma centers in the 15 days after the shelter-in-place order went into effect on 16 March 2020, compared with 389 activations during the same time period in 2018 and 2019 (p<0.0001). There were no other statistically significant changes to the epidemiology of trauma activations. Only one trauma activation had a positive COVID-19 test.

Discussion

Overall trauma activations decreased 4.8-fold after the shelter-in-place order went into effect in Santa Clara County on 16 March 2020, with no other effect on the epidemiology of persons presenting after traumatic injury.

Conclusion

Shelter-in-place orders may reduce strain on healthcare systems by diminishing hospital admissions from trauma, in addition to reducing virus transmission.

Derivation and Validation of a Model to Predict 30-Day Readmission in Surgical Patients Discharged to Skilled Nursing Facility

OBJECTIVES

To identify factors associated with 30-day all-cause readmission rates in surgical patients discharged to skilled nursing facilities (SNFs), and derive and validate a risk score.

DESIGN

Retrospective cohort.

SETTING AND PARTICIPANTS

Patients admitted to 1 tertiary hospital's surgical services between January 1, 2011, and December 31, 2014 and subsequently discharged to 110 SNFs within a 25-mile radius of the hospital. The first 2 years were used for the derivation set and the last 2 for validation.

METHODS

Data were collected on 30-day all cause readmissions, patient demographics, procedure and surgical service, comorbidities, laboratory tests, and prior health care utilization. Multivariate regression was used to identify risk factors for readmission.

RESULTS

During the study period, 2405 surgical patients were discharged to 110 SNFs, and 519 (21.6%) of these patients experienced readmission within 30 days. In a multivariable regression model, hospital length of stay [odds ratio (OR) per day: 1.03, 95% confidence interval (CI) 1.02-1.04], number of hospitalizations in past year (OR 1.24 per hospitalization, 95% CI 1.18-1.31), nonelective surgery (OR 1.33, 95% CI 1.18-1.65), low-risk service (orthopedic/spine service) (OR 0.32, 95% CI 0.25-0.42), and intermediate-risk service (cardiothoracic surgery/urology/gynecology/ear, nose, throat) (OR 0.69, 95% CI 0.53-0.88) were associated with all-cause readmissions. The model had a C index of 0.71 in the validation set. Using the following risk score [0.8 × (hospital length of stay) + 7 × (number of hospitalizations in past year) +10 for nonelective surgery, +36 for high-risk surgery, and +20 for intermediate-risk surgery], a score of >40 identified patients at high risk of 30-day readmission (35.8% vs 12.6%, P < .001).

CONCLUSIONS/IMPLICATIONS

Among surgical patients discharged to an SNF, a simple risk score with 4 parameters can accurately predict the risk of 30-day readmission.

Financial Stability of Level I Trauma Centers Within Safety-Net Hospitals

BACKGROUND

Level I trauma centers often exist within safety-net hospitals (SNHs), facilities servicing high proportions of low-income and uninsured patients. Given the current health care funding environment, trauma centers within SNHs may be at particular risk. Using California as a model, we hypothesized that SNHs with trauma centers vary in terms of financial stability.

STUDY DESIGN

We performed a retrospective cohort study using data from publicly available financial disclosure reports from California's Office of Statewide Health Planning and Development. Safety-net hospitals were identified from the California Association of Public Hospitals and Health Systems. The primary outcomes metric for financial performance was operating margin.

RESULTS

California hospitals with Level I trauma centers were analyzed (11 SNH sites, 2 non SNH). The SNHs did not behave uniformly, and were clustered into county-owned SNHs (36%, n = 4) and nonprofit-owned SNHs (64%, n = 7). Mean operating margins for county SNHs, nonprofit SNHs, and non SNHs were -16.5%, 8.4%, and 9.5%, respectively (p < 0.001). From 2010 to 2015, operating margins improved for all hospitals, partly due to increases in the percent of insured patients and changes in payer mix. Nonprofit SNHs had a payer mix similar to that of non SNHs; county SNHs had the highest proportions of MediCal (California Medicaid) (45% vs 36% vs 12%, respectively, p < 0.001) and uninsured patients (17% vs 5% vs 0%, respectively, p < 0.001) compared with nonprofit SNHs and non SNHs, respectively.

CONCLUSIONS

The majority (85%) of Level I trauma centers are within SNHs, whose financial stability is highly variable. A group of SNHs rely on infusions of government funds and are therefore susceptible to changes in policy. These findings suggest deliberate funding efforts are critical to protect the health of the US academic trauma system.

A geospatial evaluation of timely access to surgical care in seven countries

OBJECTIVE

To assess the consistent availability of basic surgical resources at selected facilities in seven countries.

METHODS

In 2010-2014, we used a situational analysis tool to collect data at district and regional hospitals in Bangladesh (n = 14), the Plurinational State of Bolivia (n = 18), Ethiopia (n = 19), Guatemala (n = 20), the Lao People's Democratic Republic (n = 12), Liberia (n = 12) and Rwanda (n = 25). Hospital sites were selected by pragmatic sampling. Data were geocoded and then analysed using an online data visualization platform. Each hospital's catchment population was defined as the people who could reach the hospital via a vehicle trip of no more than two hours. A hospital was only considered to show consistent availability of basic surgical resources if clean water, electricity, essential medications including intravenous fluids and at least one anaesthetic, analgesic and antibiotic, a functional pulse oximeter, a functional sterilizer, oxygen and providers accredited to perform surgery and anaesthesia were always available.

FINDINGS

Only 41 (34.2%) of the 120 study hospitals met the criteria for the provision of consistent basic surgical services. The combined catchments of the study hospitals in each study country varied between 3.3 million people in Liberia and 151.3 million people in Bangladesh. However, the combined catchments of the study hospitals in each study country that met the criteria for the provision of consistent basic surgical services were substantially smaller and varied between 1.3 million in Liberia and 79.2 million in Bangladesh.

CONCLUSION

Many study facilities were deficient in the basic infrastructure necessary for providing basic surgical care on a consistent basis.
