Trauma-induced insurance instability: Variation in insurance coverage for patients who experience readmission after injury

Emergency Medicaid enrollment after traumatic injury predicts long-term health care utilization

BACKGROUND

Injured patients have high rates of uninsurance, which is associated with worse outcomes. Insurance linkage programs that connect patients to Medicaid coverage can prevent catastrophic costs for patients. Less is known about the long-term impact of insurance enrollment. We examined health care utilization for previously uninsured patients, hypothesizing that newly insured patients postinjury would use health care more than those remaining uninsured.

METHODS

We linked institutional trauma registry data to the electronic medical record to identify injured patients aged 18 to 64 years from 2017 to 2021. Patients admitted without insurance and then retroactively insured (RI) during hospitalization were compared with patients with preestablished Medicaid (Medicaid insured [MI]) and those remaining uninsured. We compared demographic and injury characteristics and future health care utilization, including hospitalizations, emergency department (ED) visits, and clinic visits, among groups at 30 days and 12 months postinjury. Patient-reported outcomes (PROs) 6 months after injury were compared by group for a subset of patients participating in an ongoing study of long-term PROs.

RESULTS

We compared 494 RI patients with 1,706 MI and 148 uninsured patients. Retroactively insured patients were younger, more likely to have penetrating injuries, and longer hospitalization than other groups. There was a significant increase in ED and clinic visits and hospital admissions at 30 days and 12 months between RI and uninsured patients ( p < 0.001). Using multivariable logistic regression, RI was associated with higher future ED utilization, hospital admissions, and specialist visits at 30 days and 12 months compared with uninsured patients. Of the 265 patients with 6-month PROs, Medicaid coverage was not associated with any significant difference in physical function or anxiety.

CONCLUSION

Patients enrolled in insurance postinjury are more likely to use health care in the future than patients without insurance, but the downstream effects are less clear. Health insurance is a necessary step but not independently sufficient to optimize care and improve health outcomes.

Awaiting insurance coverage: Medicaid enrollment and post-acute care use after traumatic injury

BACKGROUND

Lack of insurance after traumatic injury is associated with decreased use of postacute care and poor outcomes. Insurance linkage programs enroll eligible patients in Medicaid at the time of an unplanned admission. We hypothesized that Medicaid enrollment would be associated with increased use of postacute care, but also with prolonged hospital length of stay (LOS) while awaiting insurance authorization.

METHODS

We linked trauma registry and EMR data to identify patients ages 18 years to 64 years admitted from 2017 to 2021 to a Level I trauma center. Patients admitted without insurance and retroactively insured (RI) during hospitalization were compared with patients with established Medicaid (MI) and those remaining uninsured (UI). We measured postacute care use including home health care, rehabilitation, and skilled nursing facilities. We tested the association between insurance status and discharge disposition and LOS (primary outcome) using multivariable negative binomial regression. Direct costs were compared between groups.

RESULTS

We compared 494 RI patients to 1706 MI and 148 UI patients. Retroactively insured patients had longer hospitalization (median LOS [interquartile range], 4 days [2-9 days]) than other groups (MI, 4 [2-8] and UI 2 [1-3]), p < 0.001). Retroactively insured patients were more likely to be discharged with home health care and to inpatient rehabilitation than UI patients ( p < 0.001). After adjusting for injury and management characteristics, RI was associated with longer LOS compared with MI for patients discharged to inpatient facilities ( p < 0.001). Median costs for RI patients discharged to a facility were $10,284 higher than MI patients, ranging from $8,582 for Injury Severity Score <9 to $51,883 for Injury Severity Score ≥25.

CONCLUSION

Enrollment in Medicaid after traumatic injury is associated with postacute care use, but the current enrollment process may delay discharge. Streamlining insurance enrollment and permitting discharge with pending application status could reduce unnecessary hospital days, saving costs and improving improve patient experience.

Do emergency Medicaid programs improve post-discharge health care access for trauma patients? A statewide mixed-methods study

BACKGROUND

Hospital presumptive eligibility (HPE) emergency Medicaid programs offset patient bills at hospitalization and can provide long-term Medicaid coverage. We characterized postdischarge outpatient health care utilization among HPE Medicaid trauma patients and identified patient access facilitators and barriers once newly insured. We hypothesized utilization would be increased among HPE trauma patients compared with other HPE patients, but that challenges in access to care would remain.

METHODS

We performed a convergent mixed methods study of California HPE beneficiaries using a 2016 to 2021 customized statewide longitudinal claims dataset from the Department of Health Care Services. We compared adults 18 years and older with a diagnosis to other HPE patients. Patients were tracked for 2 months postdischarge to evaluate health care utilization: outpatient specialist visits, emergency room (ER) visits, readmissions, and mental health. Thematic analysis of semistructured interviews with HPE Medicaid patients aimed to understand facilitators and barriers to access to care (n = 20).

RESULTS

Among 199,885 HPE patients, 39,677 (19.8%) had a primary diagnosis of trauma. In the 2 months postdischarge, 40.8% of trauma vs. 36.6% of nontrauma accessed outpatient specialist services; 18.6% vs. 17.2% returned to ED, 8.4% vs. 10.2% were readmitted; and 1.4% vs. 1.8% accessed mental health services. In adjusted analyses, trauma HPE patients had 1.18 increased odds of accessing outpatient specialist services ( p < 0.01). Patients cited HPE facilitators to accessing care: rapid insurance acquisition, outpatient follow-up, hospital staff support, as well as ongoing barriers to access (HPE program information recall, lack of hospital staff follow up postdischarge, and difficulty navigating a complex health care system).

CONCLUSION

Hospital presumptive eligibility Medicaid is associated with higher rates of outpatient specialist visits and fewer readmissions following injury, suggesting improved trauma patient access. Opportunities to improve appropriateness of health care utilization include more robust and longitudinal education and engagement with HPE Medicaid patients to help them navigate newfound access to services.

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 health care system-the patient, the health care 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.

Hospital Presumptive Eligibility Emergency Medicaid Programs: An Opportunity for Continuous Insurance Coverage?

BACKGROUND

Lack of health insurance is a public health crisis, leading to foregone care and financial strain. Hospital Presumptive Eligibility (HPE) is a hospital-based emergency Medicaid program that provides temporary (up to 60 d) coverage, with the goal that hospitals will assist patients in applying for ongoing Medicaid coverage. It is unclear whether HPE is associated with successful longer-term Medicaid enrollment.

OBJECTIVE

To characterize Medicaid enrollment 6 months after initiation of HPE and determine sociodemographic, clinical, and geographic factors associated with Medicaid enrollment.

DESIGN

This was a cohort study of all HPE approved inpatients in California, using claims data from the California Department of Healthcare Services.

SETTING

The study was conducted across all HPE-participating hospitals within California between January 1, 2016 and December 31, 2017.

PARTICIPANTS

We studied California adult hospitalized inpatients, who were uninsured at the time of hospitalization and approved for HPE emergency Medicaid. Using multivariable logistic regression models, we compared HPE-approved patients who enrolled in Medicaid by 6 months versus those who did not.

EXPOSURES

HPE emergency Medicaid approval at the time of hospitalization.

MAIN OUTCOMES AND MEASURES

The primary outcome was full-scope Medicaid enrollment by 6 months after the hospital's presumptive eligibility approval.

RESULTS

Among 71,335 inpatient HPE recipients, a total of 45,817 (64.2%) enrolled in Medicaid by 6 months. There was variability in Medicaid enrollment across counties in California (33%-100%). In adjusted analyses, Spanish-preferred-language patients were less likely to enroll in Medicaid (aOR 0.77, P <0.001). Surgical intervention (aOR 1.10, P <0.001) and discharge to another inpatient facility or a long-term care facility increased the odds of Medicaid enrollment (vs. routine discharge home: aOR 2.24 and aOR 1.96, P <0.001).

CONCLUSION

California patients who enroll in HPE often enroll in Medicaid coverage by 6 months, particularly among patients requiring surgical intervention, repeated health care visits, and ongoing access to care. Future opportunities include prospective evaluation of HPE recipients to understand the impact that Medicaid enrollment has on health care utilization and financial solvency.

Changes in payer mix of new and established trauma centers: the new trauma center money grab?

Background

Although timely access to trauma center (TC) care for injured patients is essential, the proliferation of new TCs does not always improve outcomes. Hospitals may seek TC accreditation for financial reasons, rather than to address community or geographic need. Introducing new TCs risks degrading case and payer mix at established TCs. We hypothesized that newly accredited TCs would see a disproportionate share of commercially insured patients.

Study design

We collected data from all accredited adult TCs in Pennsylvania using the state trauma registry from 1999 to 2018. As state policy regarding supplemental reimbursement for underinsured patients changed in 2004, we compared patient characteristics and payer mix between TCs established before and after 2004. We used multivariable logistic regression to assess the relationship between payer and presentation to a new versus established TC in recent years.

Results

Over time, there was a 40% increase in the number of TCs from 23 to 38. Of 326 204 patients from 2010 to 2018, a total of 43 621 (13.4%) were treated at 15 new TCs. New TCs treated more blunt trauma and less severely injured patients (p<0.001). In multivariable analysis, patients presenting to new TCs were more likely to have Medicare (OR 2.0, 95% CI 1.9 to 2.1) and commercial insurance (OR 1.6, 95% CI 1.5 to 1.6) compared with Medicaid. Over time, fewer patients at established TCs and more patients at new TCs had private insurance.

Conclusions

With the opening of new centers, payer mix changed unfavorably at established TCs. Trauma system development should consider community and regional needs, as well as impact on existing centers to ensure financial sustainability of TCs caring for vulnerable patients.

Financial toxicity part II: A practical guide to measuring and tracking long-term financial outcomes among acute care surgery patients

ABSTRACT

Acute care surgery (ACS) patients are frequently faced with significant long-term recovery and financial implications that extend far beyond their hospitalization. While major injury and emergency general surgery (EGS) emergencies are often viewed solely as acute moments of crisis, the impact on patients can be lifelong. Financial outcomes after major injury or emergency surgery have only begun to be understood. The Healthcare Economics Committee from the American Association for the Surgery of Trauma previously published a conceptual overview of financial toxicity in ACS, highlighting the association between financial outcomes and long-term physical recovery. The aims of second-phase financial toxicity review by the Healthcare Economics Committee of the American Association for the Surgery of Trauma are to (1) understand the unique impact of financial toxicity on ACS patients; (2) delineate the current limitations surrounding measurement domains of financial toxicity in ACS; (3) explore the "when, what and how" of optimally capturing financial outcomes in ACS; and (4) delineate next steps for integration of these financial metrics in our long-term patient outcomes. As acute care surgeons, our patients' recovery is often contingent on equal parts physical, emotional, and financial recovery. The ACS community has an opportunity to impact long-term patient outcomes and well-being far beyond clinical recovery.

Do hospital-based emergency Medicaid programs benefit trauma centers? A mixed-methods analysis

INTRODUCTION

Hospital Presumptive Eligibility (HPE) is a temporary Medicaid insurance at hospitalization, which can offset patient costs of care, increase access to postdischarge resources, and provide a path to sustain coverage through Medicaid. Less is known about the implications of HPE programs on trauma centers (TCs). We aimed to describe the association with HPE and hospital Medicaid reimbursement and characterize incentives for HPE participation among hospitals and TCs. We hypothesized that there would be financial, operational, and mission-based incentives.

METHODS

We performed a convergent mixed methods study of HPE hospitals in California (including all verified TCs). We analyzed Annual Financial Disclosure Reports from California's Department of Health Care Access and Information (2005-2021). Our primary outcome was Medicaid net revenue. We also conducted thematic analysis of semistructured interviews with hospital stakeholders to understand incentives for HPE participation (n = 8).

RESULTS

Among 367 California hospitals analyzed, 285 (77.7%) participate in HPE, 77 (21%) of which are TCs. As of early 2015, 100% of TCs had elected to enroll in HPE. There is a significant positive association between HPE participation and net Medicaid revenue. The highest Medicaid revenues are in HPE level I and level II TCs. Controlling for changes associated with the Affordable Care Act, HPE enrollment is associated with increased net patient Medicaid revenue ( b = 6.74, p < 0.001) and decreased uncompensated care costs ( b = -2.22, p < 0.05). Stakeholder interviewees' explanatory incentives for HPE participation included reduction of hospital bad debt, improved patient satisfaction, and community benefit in access to care.

CONCLUSION

Hospital Presumptive Eligibility programs not only are a promising pathway for long-term insurance coverage for trauma patients but also play a role in TC viability. Future interventions will target streamlining the HPE Medicaid enrollment process to reduce resource burden on participating hospitals and ensure ongoing patient engagement in the program.

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.

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.

Evaluating emergency Medicaid program policy changes during the Covid-19 pandemic

Background

Trauma patients are twice as likely to be uninsured as the general population, which can lead to limited access to post-injury resources and higher mortality. The Hospital Presumptive Eligibility (HPE) program offers emergency Medicaid for eligible patients at presentation. The HPE program underwent several changes during the Covid-19 pandemic, we quantify the program’s success during this time, and seek to understand features associated with HPE approval.

Material and Methods

A mixed-methods study at a Level I trauma center using explanatory sequential design, including: 1) a retrospective cohort analysis (2015-2021) comparing HPE approval before and after Covid-19 policy changes; 2) semi-structured interviews with key stakeholders.

Results

589 patients listed as self-pay or Medicaid presented after March 16, 2020, when Covid-19 policies were first implemented. Of these, 409 (69%) patients were already enrolled in Medicaid at hospitalization. Among those uninsured at arrival, 160 (89%) were screened, and 98 (61%) were approved for HPE. This marks a significant improvement in the pre-pandemic HPE approval rate (48%). In adjusted logistic regression analyses, the Covid-19 period was associated with an increased likelihood of HPE approval (vs. pre-pandemic: aOR, 1.64; p = 0.005). Qualitative interviews suggest that mechanisms include state-based expansion in HPE eligibility and improvements in remote approval such as telephone/video conferencing.

Conclusion

The HPE program experienced an overall increased approval rate and adapted to policy changes during the pandemic, enabling more patients’ access to health insurance. Ensuring that these beneficial changes remain a part of our health policy is an important aspect of improving access to health insurance for our patients.

Emergency Medicaid programs may be an effective means of providing sustained insurance among trauma patients: A statewide longitudinal analysis

BACKGROUND

Hospital Presumptive Eligibility (HPE) is a temporary Medicaid insurance at hospitalization that offsets costs of care, increases access to postdischarge resources, and provides patients with a path to sustain coverage through Medicaid. Because HPE only lasts up to 60 days, we aimed to determine Medicaid insurance status 6 months after injury among HPE-approved trauma patients and identify factors associated with successful sustainment.

METHODS

Using a customized longitudinal claims data set for HPE-approved patients from the California Department of Health Care Services, we analyzed adults with a primary trauma diagnosis (International Classification of Diseases version 10) who were HPE approved in 2016 and 2017. Our primary outcome was Medicaid sustainment at 6 months. Univariate and multivariate analyses were performed.

RESULTS

A total of 9,749 trauma patients with HPE were analyzed; 6,795 (69.7%) sustained Medicaid at 6 months. Compared with patients who did not sustain, those who sustained had higher Injury Severity Score (ISS > 15: 73.5% vs. 68.7%, p < 0.001), more frequent surgical intervention (74.8% vs. 64.5%, p < 0.001), and were more likely to be discharged to postacute services (23.9% vs. 10.4%, p < 0.001). Medicaid sustainment was high among patients who identified as White (86.7%), Hispanic (86.7%), Black (84.3%), and Asian (83.7%). Medicaid sustainment was low among the 2,505 patients (25.7%) who declined to report race, ethnicity, or preferred language (14.8% sustainment). In adjusted analyses, major injuries (ISS > 16) (vs. ISS < 15: adjusted odds ratio [aOR], 1.51; p = 0.02) and surgery (aOR, 1.85; p < 0.001) were associated with increased likelihood of Medicaid sustainment. Declining to disclose race, ethnicity, or language (aOR, 0.05; p < 0.001) decreased the likelihood of Medicaid sustainment.

CONCLUSION

Hospital Presumptive Eligibility programs are a promising pathway for securing long-term insurance coverage for trauma patients, particularly among the severely injured who likely require ongoing access to health care services. Patient and provider interviews would help to elucidate barriers for patients who do not sustain.

Financial Burden of Traumatic Injury Amongst the Privately Insured

OBJECTIVE

We sought to evaluate the overall financial burden associated with traumatic injury amongst patients with private insurance and assess the effect of high deductible plans on out-of-pocket costs (OOPCs).

SUMMARY OF BACKGROUND DATA

Traumatic injury can be a source of unexpected financial burden for households. However, the effect of increasing participation in higher cost-sharing private health insurance plans remains unknown.

METHODS

We conducted a retrospective cohort observational study, using the Clinformatics Data Mart Database, a nationwide single-payer administrative claims database to identify US adults who required emergency department services or hospital admission for single traumatic injury from 2008 to 2018. A 2-part model using a logistic regression and a generalized linear model with gamma distribution and log link was used to evaluate 12-month OOPCs after traumatic injury. Multivariable logistic regression was used to evaluate the likelihood of catastrophic health expenditure (CHE) after injury.

RESULTS

Of 426,945 included patients, 53% were male, 71% were white, and median age was 42 years. Patients faced monthly OOPC of $660 at the time of their injury. High deductible plan enrollment was associated with an increase of $1703 in 12-month OOPC after trauma, compared to those covered by traditional health plans. In addition to high deductible health plan enrollment, worsening injury severity and longer hospital stays were also associated with increased 12-month OOPC after trauma. Non-white minorities paid less 12-month OOPC after trauma compared to non-Hispanic white patients, but also used fewer services. Overall, the incidence of CHE was 5%; however high-deductible health plan enrollees faced a 13% chance of CHE.

CONCLUSIONS

Privately insured trauma patients face substantial OOPCs at the time of their injuries. High-deductible health plans are associated with increased financial vulnerability after trauma.

Acquisition of Medicaid at the time of injury: An opportunity for sustainable insurance coverage

INTRODUCTION

Uninsured trauma patients are at higher risk of mortality, limited access to postdischarge resources, and catastrophic health expenditure. Hospital Presumptive Eligibility (HPE), enacted with the 2014 Affordable Care Act, enables uninsured patients to be screened and acquired emergency Medicaid at the time of hospitalization. We sought to identify factors associated with successful acquisition of HPE insurance at the time of injury, hypothesizing that patients with higher Injury Severity Score (ISS) (ISS >15) would be more likely to be approved for HPE.

METHODS

We identified Medicaid and uninsured patients aged 18 to 64 years with a primary trauma diagnosis (International Classification of Diseases, Tenth Revision) in a large level I trauma center between 2015 and 2019. We combined trauma registry data with review of electronic medical records, to determine our primary outcome, HPE acquisition. Descriptive and multivariate analyses were performed.

RESULTS

Among 2,320 trauma patients, 1,374 (59%) were already enrolled in Medicaid at the time of hospitalization. Among those uninsured at arrival, 386 (40.8%) acquired HPE before discharge, and 560 (59.2%) remained uninsured. Hospital Presumptive Eligibility patients had higher ISS (ISS >15, 14.8% vs. 5.7%; p < 0.001), longer median length of stay (2 days [interquartile range, 0-5 days] vs. 0 [0-1] days, p < 0.001), were more frequently admitted as inpatients (64.5% vs. 33.6%, p < 0.001), and discharged to postacute services (11.9% vs. 0.9%, p < 0.001). Patient, hospital, and policy factors contributed to HPE nonapproval. In adjusted analyses, Hispanic ethnicity (vs. non-Hispanic Whites: aOR, 1.58; p = 0.02) and increasing ISS (p ≤ 0.001) were associated with increased likelihood of HPE approval.

CONCLUSION

The time of hospitalization due to injury is an underused opportunity for intervention, whereby uninsured patients can acquire sustainable insurance coverage. Opportunities to increase HPE acquisition merit further study nationally across trauma centers. As administrative and trauma registries do not capture information to compare HPE and traditional Medicaid patients, prospective insurance data collection would help to identify targets for intervention.

High Cost and Resource Utilization of Frostbite Readmissions in the United States

BACKGROUND

Frostbite is a high morbidity, high-cost injury that can lead to digit or limb necrosis requiring amputation. Our primary aim is to describe the rate of readmission following frostbite injury. Our secondary aims are to describe the overall burden of care, cost, and characteristics of repeat hospitalizations of frostbite-injured people.

METHODS

Hospitalizations following frostbite injury (index and readmissions) were identified in the 2016 and 2017 Nationwide Readmission Database. Multivariable logistic regression was clustered by hospital and additionally adjusted for severe frostbite injury, gender, year, payor group, severity, and comorbidity index. Population estimates were calculated and adjusted for by using survey weight, sampling clusters, and stratum.

RESULTS

In the two-year cohort, 1,065 index hospitalizations resulted in 1,907 total hospitalizations following frostbite injury. Most patients were male (80.3%), lived in metropolitan/urban areas (82.3%), and nearly half were insured with Medicaid (46.4%). Of the 842 readmissions, 53.7% were associated with complications typically associated with frostbite injury. Overall, 29% of frostbite injuries resulted in at least one amputation. The average total cost and total LOS of readmissions was $236,872 and 34.7 days. Drug or alcohol abuse, homelessness, Medicaid insurance, and discharge AMA were independent predictors of unplanned readmission. Factors associated with multiple readmissions include discharge AMA and Medicare Insurance, but not drug or alcohol abuse or homelessness. The population-based estimated unplanned readmission rate following frostbite injury was 35.4% (95% CI 32.2 - 38.6%).

CONCLUSIONS

This is the first study examining readmissions following frostbite injury on a national level. Drug or alcohol abuse, homelessness, Medicaid insurance, and discharge AMA were independent predictors of unplanned readmission, while only AMA discharge and Medicare insurance were associated with multiple readmissions. Supportive resources (community and hospital-based) may reduce unplanned readmissions of frostbite injured patients with those additional risk factors.

Unplanned readmission after traumatic injury: A long-term nationwide analysis

BACKGROUND

Long-term outcomes after trauma admissions remain understudied. We analyzed the characteristics of inpatient readmissions within 6 months of an index hospitalization for traumatic injury.

METHODS

Using the 2010 to 2015 Nationwide Readmissions Database, which captures data from up to 27 US states, we identified patients at least 15 years old admitted to a hospital through an emergency department for blunt trauma, penetrating trauma, or burns. Exclusion criteria included hospital transfers, patients who died during their index hospitalizations, and hospitals with fewer than 100 trauma patients annually. After calculating the incidences of all-cause, unplanned inpatient readmissions within 1 month, 3 months, and 6 months, we used multivariable logistic regression models to identify predictors of readmissions. Analyses adjusted for patient, clinical, and hospital factors.

RESULTS

Among 2,763,890 trauma patients, the majority had blunt injuries (92.5%), followed by penetrating injuries (6.2%) and burns (1.5%). Overall, rates of inpatient readmissions were 11.1% within 1 month, 21.6% within 6 months, and 29.8% within 6 months, with limited variability by year. After adjustment, the following were associated with all-cause 6 months inpatient readmissions: male sex (adjusted odds ratio [aOR], 1.10; 95% confidence interval [95% CI], 1.09-1.10), comorbidities (aOR, 1.21; 95% CI, 1.21-1.22), low-income quartiles (first and second) (aOR, 1.08; 95% CI, 1.07-1.10 and aOR, 1.04; 95% CI, 1.03-1.06, respectively), Medicare (aOR, 1.65; 95% CI, 1.62-1.69), Medicaid (aOR, 1.51; 95% CI, 1.48-1.53), being treated at private, investor-owned hospitals (aOR, 1.15; 95% CI, 1.12-1.18), longer hospital length of stay (aOR, 1.01; 95% CI, 1.01-1.01) and patient disposition to short-term hospital (aOR, 1.55; 95% CI, 1.49-1.62), skilled nursing facility (aOR, 1.43; 95% CI, 1.42-1.45), home health care (aOR, 1.27; 95% CI, 1.25-1.28), or leaving against medical advice (aOR, 1.85; 95% CI, 1.78-1.92).

CONCLUSION

Unplanned readmission after trauma is high and remains this way 6 months after discharge. Understanding the factors that increase the odds of readmissions within 1 month, 3 months, and 6 months offer a focus for quality improvement and have important implications for hospital benchmarking.

An investigation of social determinants of health and outcomes in pediatric nonaccidental trauma

OBJECTIVES

Nonaccidental trauma (NAT) is a leading cause of pediatric mortality and disability. We examined our institution's experience with NAT to determine if socioeconomic status is correlated with patient outcomes.

METHODS

NAT cases were reviewed retrospectively. Socioeconomic determinants included insurance status and race; outcomes included mortality, discharge disability and disposition. Correlations were identified using t test, Fisher's exact test, and logistic regression.

RESULTS

The cohort comprised of 337 patients, with an overall uninsured rate of 5.6%. This rate was achieved by insuring 64.7% of the cohort after admission. Non-survivors were more likely to have no insurance coverage (14.8% versus 4.8%, p = 0.041). Regression revealed that uninsured had 8 times (95% CI 1.7-38.7, p = 0.008) higher in-hospital mortality than those with insurance when controlling for injury severity. Additionally, injury severity score ≥ 15, transfer from outside hospital, need for ICU or operative treatment were predictive of mortality. Adjusted risk factors for severe disability at discharge did not include insurance status or race, while ISS ≥ 15 and ICU stay were predictive.

CONCLUSIONS

There are significant associations of insurance status with pediatric NAT outcomes, highlighting that determinants other than disease severity may influence mortality and morbidity. High-risk patients should be identified to develop strategies to improve outcomes.
