Socioeconomic factors are associated with frequency of repeat emergency department visits for pediatric closed fractures

Racial Disparities Exist in 90-Day Unplanned Return to the Emergency Department Following Orthopaedic Trauma Surgery

OBJECTIVES

Racial disparities in healthcare outcomes exist, including in orthopaedic trauma care. The aim of this study was to determine the impact of race, social deprivation, and payor status on 90-day emergency department (ED) revisits among orthopaedic trauma surgery patients at a Level 1 trauma academic medical center.

METHODS

DESIGN

Retrospective chart review analysis.

SETTING

Level 1 trauma academic center in Durham, NC.

PATIENT SELECTION CRITERIA

Adult patients undergoing orthopaedic trauma surgery between 2017 and 2021.

OUTCOME MEASURES AND COMPARISONS

The primary outcome of this retrospective cohort study was 90-day return to the ED. Logistic regression analysis was performed for variables of interest [race, social deprivation (measured by the Area Deprivation Index), and payor status] separately and combined, with each model adjusting for distance to the hospital. Results were interpreted as odds ratios (ORs) of 90-day ED revisits comparing levels of the respective variables. Statistical significance was assessed at α = 0.05.

RESULTS

A total of 3120 adult patients who underwent orthopaedic trauma surgery between 2017 and 2021 were included in the analysis. Black race (OR = 1.47; 95% confidence interval [CI]: 1.17-1.84, P < 0.001) and Medicaid coverage (OR = 1.63, 95% CI: 1.20-2.21, P = 0.002) were significantly associated with higher odds of return to ED compared with non-Black or non-Medicaid-covered patients. While ethnic minority (Hispanic/Latino or non-White) was statistically significant while adjusting only for distance to the hospital (OR = 1.23, 95% CI: 1.00-1.50, P = 0.047), it was no longer significant after adjusting for the other sociodemographic variables (OR = 1.13, 95% CI: 0.91-1.39, P = 0.27). The weighted Area Deprivation Index was not associated with a difference in odds of return to ED in any adjusted models.

CONCLUSIONS

The results highlight the presence of racial and socioeconomic disparities in ED utilization, with Black race and Medicaid coverage significantly associated with higher odds of return to the ED. Future research should delve deeper into comprehending the root causes contributing to these racial and socioeconomic utilization disparities and evaluate the effectiveness of targeted interventions to reduce them.

Pediatric Trauma Recidivism: A Statewide Risk Factor Analysis of the Maryland Health Services Cost Review Commission (HSCRC)

BACKGROUND

National estimates suggest pediatric trauma recidivism is uncommon but are limited by short follow up and narrow ascertainment. We aimed to quantify the long-term frequency of trauma recidivism in a statewide pediatric population and identify risk factors for re-injury.

METHODS

The Maryland Health Services Cost Review Commission Dataset was queried for 0-19-year-old patients with emergency department or inpatient encounters for traumatic injuries between 2013 and 2019. We measured trauma recidivism by identifying patients with any subsequent presentation for a new traumatic injury. Univariate and multivariable regressions were used to estimate associations of patient and injury characteristics with any recidivism and inpatient recidivism.

RESULTS

Of 574,472 patients with at least one injury encounter, 29.6% experienced trauma recidivism. Age ≤2 years, public insurance, and self-inflicted injuries were associated with recidivism regardless of index treatment setting. Of those with index emergency department presentations 0.06% represented with an injury requiring inpatient admission; unique risk factors for ED-to-inpatient recidivism were age >10 years (aOR 1.61), cyclist (aOR 1.31) or burn (aOR 1.39) mechanisms, child abuse (aOR 1.27), and assault (aOR 1.43). Among patients with at least one inpatient encounter, 6.3% experienced another inpatient trauma admission, 3.4% of which were fatal. Unique risk factors for inpatient-to-inpatient recidivism were firearm (aOR 2.48) and motor vehicle/transportation (aOR 1.62) mechanisms of injury (all p < 0.05).

CONCLUSIONS

Pediatric trauma recidivism is more common and morbid than previously estimated, and risk factors for repeat injury differ by treatment setting. Demographic and injury characteristics may help develop and target setting-specific interventions.

Social Determinants of Health and Pediatric Emergency Department Outcomes: A Systematic Review and Meta-Analysis of Observational Studies

STUDY OBJECTIVE

Social determinants of health contribute to disparities in pediatric health and health care. Our objective was to synthesize and evaluate the evidence on the association between social determinants of health and emergency department (ED) outcomes in pediatric populations.

METHODS

This review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Equity Extension guidelines. Observational epidemiological studies were included if they examined at least 1 social determinant of health from the PROGRESS-Plus framework in relation to ED outcomes among children <18 years old. Effect direction plots were used for narrative results and pooled odds ratios (pOR) with 95% confidence intervals (CI) for meta-analyses.

RESULTS

Fifty-eight studies were included, involving 17,275,090 children and 103,296,839 ED visits. Race/ethnicity and socioeconomic status were the most reported social determinants of health (71% each). Black children had 3 times the odds of utilizing the ED (pOR 3.16, 95% CI 2.46 to 4.08), whereas visits by Indigenous children increased the odds of departure prior to completion of care (pOR 1.58, 95% CI 1.39 to 1.80) compared to White children. Public insurance, low income, neighborhood deprivation, and proximity to an ED were also predictors of ED utilization. Children whose caregivers had a preferred language other than English had longer length of stay and increased hospital admission.

CONCLUSION

Social determinants of health, particularly race, socioeconomic deprivation, proximity to an ED, and language, play important roles in ED care-seeking patterns of children and families. Increased utilization of ED services by children from racial minority and lower socioeconomic status groups may reflect barriers to health insurance and access to health care, including primary and subspecialty care, and/or poorer overall health, necessitating ED care. An intersectional approach is needed to better understand the trajectories of disparities in pediatric ED outcomes and to develop, implement, and evaluate future policies.

Poor socioeconomic status is associated with delayed femoral fracture fixation in adolescent patients

INTRODUCTION

Healthcare disparities continue to exist in pediatric orthopedic care. Femur fractures are the most common diaphyseal fracture and the leading cause of pediatric orthopedic hospitalization. Prompt time to surgical fixation of femur fractures is associated with improved outcomes.

OBJECTIVE

The objective of this study was to evaluate associations between socioeconomic status and timing of femoral fixation in adolescents on a nationwide level.

METHODS

The 2016-2020 National Inpatient Sample (NIS) database was queried using International Classification of Disease, 10th edition (ICD-10) codes for repair of femur fractures. Patients between the ages of 10 and 19 years of age with a principal diagnosis of femur fracture were selected. Patients transferred from outside hospitals were excluded. Baseline demographics and characteristics were described. Patients were categorized as poor socioeconomic status (PSES) if they were classified in the Healthcare Cost and Utilization Project's (HCUP) lowest 50th percentile median income household categories and on Medicaid insurance. The primary outcome studied was timing to femur fixation. Delayed fixation was defined as fixation occurring after 24 h of admission. Secondary outcomes included length of stay (LOS) and discharge disposition.

RESULTS

From 2016-2020, 10,715 adolescent patients underwent femur fracture repair throughout the United States. Of those, 765 (7.1 %) underwent late fixation. PSES and non-white race were consistently associated with late fixation, even when controlling for injury severity. Late fixation was associated with decreased rate of routine discharge (p < 0.01), increased LOS (p < 0.01) and increased total charges (p < 0.01).

CONCLUSION

Patients of PSES or non-white race were more likely to experience delayed femoral fracture fixation. Delayed fixation led to worse outcomes and increased healthcare resource utilization. Research studying healthcare disparities may provide insight for improved provider education, implicit bias training, and comprehensive standardization of care.

Racial and Ethnic Disparities in Pediatric Musculoskeletal Care

PURPOSE OF REVIEW

This article provides a review of recent published research studying racial, ethnic, and socioeconomic disparities in pediatric musculoskeletal care.

RECENT FINDINGS

Disparities in pediatric musculoskeletal care are demonstrated in two general realms: access to care and health outcomes. Though initiatives have been proposed or enacted to address disparities, underrepresented minorities and patients from lower socioeconomic statuses continue to face barriers across the spectrum of orthopedic care and poorer ultimate outcomes after both non-operative and operative management. Minority pediatric patients and those from lower socioeconomic statuses experience delays across the spectrum of orthopedic care for both urgent and non-urgent conditions. They wait longer between injury date and initial orthopedic evaluation, longer to receipt of diagnostic imaging, and longer to ultimate treatment than their counterparts. When finally able to obtain musculoskeletal care and treatment, they are at higher risk of poor in-hospital outcomes and inpatient complications, worse patient reported outcomes, and suboptimal pain management. In the outpatient setting, they receive less physical therapy and follow-up clinic visits, resulting in greater stiffness and strength deficits, and are ultimately less likely to meet return to sport criteria.

Epidemiology of pediatric cartilage restoration procedures in the United States: insurance and geography play a role

OBJECTIVES

The purpose of this study is to analyze the epidemiology of children and adolescents undergoing osteochondral autograft transplantation (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI) in the United States.

METHODS

The Pediatric Health Information System, a national database consisting of 49 children's hospitals, was queried for all patients undergoing OAT, OCA, and ACI between 2012 and 2018. Demographic information was collected for each subject. United States Census guidelines were used to categorize hospitals geographically. Univariate analysis was followed by purposeful entry multivariate regression to adjust for confounding factors.

RESULTS

A total of 809 subjects with a mean age of 15.4 ± 2.4 years were included in the analysis. Of these, 48.6% underwent OCA, 41.9% underwent OAT, and 9.5% underwent ACI. After adjusting for confounders in a multivariate model, ACI was 3.6 times more likely to be performed in patients with private insurance than those that were publicly insured (95% CI 1.6-8.0, p = 0.002). Furthermore, a patient in the Northeast was 33.1 times more likely to undergo ACI than in the West (95% CI 4.5-246.1, p = 0.001). OAT was performed most frequently in the West and Midwest (52.4% and 51.8% of the time, respectively; p < 0.001).

CONCLUSION

In the United States, there is substantial variation in the procedures performed for cartilage restoration in children and adolescents. Though ACI is the least commonly selected operation overall, it is significantly more likely to be performed on patients with private insurance and those in the Northeast.

Assessment of Ethno-racial and Insurance-based Disparities in Pediatric Forearm and Tibial Fracture Care in the United States

INTRODUCTION

Despite growing attention to healthcare disparities and interventions to improve inequalities, additional identification of disparities is needed, particularly in the pediatric population. We used state and nationwide databases to identify factors associated with the surgical treatment of pediatric forearm and tibial fractures.

METHODS

The Healthcare Cost and Utilization Project State Inpatient, Emergency Department, and Ambulatory Surgery and Services Databases from four US states and the Nationwide Emergency Department Sample database were quarried using International Classification of Diseases codes to identify patients from 2006 to 2015. Multivariable regression models were used to determine factors associated with surgical treatment.

RESULTS

State databases identified 130,006 forearm (1575 open) and 51,979 tibial fractures (1339 open). Surgical treatment was done in 2.6% of closed and 37.5% of open forearm fractures and 7.9% of closed and 60.5% of open tibial fractures. A national estimated total of 3,312,807 closed and 46,569 open forearm fractures were included, 59,024 (1.8%) of which were treated surgically. A total of 719,374 closed and 26,144 open tibial fractures were identified; 52,506 (7.0%) were treated surgically. Multivariable regression revealed that race and/or insurance status were independent predictors for the lower likelihood of surgery in 3 of 4 groups: Black patients were 43% and 35% less likely to have surgery after closed and open forearm fractures, respectively, and patients with Medicaid were less often treated surgically for open tibial fractures in state (17%) and nationwide (20%) databases.

CONCLUSIONS

Disparities in pediatric forearm and tibial fracture care persist, especially for Black patients and those with Medicaid; identification of influencing factors and interventions to address them are important in improving equality and value of care.

Socioeconomic Status Predicts Short-Term Emergency Department Utilization Following Supratentorial Meningioma Resection

Introduction By identifying drivers of healthcare disparities, providers can better support high-risk patients and develop risk-mitigation strategies. Household income is a social determinant of health known to contribute to healthcare disparities. The present study evaluates the impact of household income on short-term morbidity and mortality following supratentorial meningioma resection. Methods A total of 349 consecutive patients undergoing supratentorial meningioma resection over a six-year period (2013-2019) were analyzed retrospectively. Primary outcomes were unplanned hospital readmission, reoperations, emergency department (ED) visits, return to the operating room, and all-cause mortality within 30 days of the index operation. Standardized univariate regression was performed across the entire sample to assess the impact of household income on outcomes. Subsequently, outcomes were compared between the lowest (household income ≤ $51,780) and highest (household income ≥ $87,958) income quartiles. Finally, stepwise regression was executed to identify potential confounding variables. Results Across all supratentorial meningioma resection patients, lower household income was correlated with a significantly increased rate of 30-day ED visits (p = 0.002). Comparing the lowest and highest income quartiles, the lowest quartile was similarly observed to have a significantly higher rate of 30-day ED evaluation (p = 0.033). Stepwise regression revealed that the observed association between household income and 30-day ED visits was not affected by confounding variables. Conclusion This study suggests that household income plays a role in short-term ED evaluation following supratentorial meningioma resection.

Predictors of appointment adherence following operative treatment of pediatric supracondylar humerus fractures: which patients are not following up?

This study aims to identify characteristics associated with poor appointment adherence after surgical stabilization of supracondylar humerus fractures (SCHFX) in children. A retrospective review of 560 consecutive, surgically managed patients with SCHFX from 2010 to 2015 was performed. One missed follow-up appointment was classified as 'low adherence', whereas missing two or more appointments was classified as 'very low adherence'. Demographics, insurance status, estimated family income and distance from clinic were analyzed to identify differences in variables between adherent and low-adherent groups. Of 560, 121 (21.8%) missed one follow-up visit and 39/560 (7.1%) missed more than two visits. Age, gender, distance traveled, insurance status and primary language were nonpredictive. Estimated income <$50 000 was associated with a >200% increase in low adherence vs patients with estimated income >$50 000 (9.3 vs 3.8%; P = 0.012). African American patients had significantly lower adherence vs patients of other races (47.5 vs 19.6%; P < 0.0001). Ethnicity remained the only significant factor correlated to adherence after multivariate analysis. African Americans were three times more likely demonstrate low adherence (P = 0.0014). Ethnicity and estimated income <$50 000 were predictors of missing two or more visits. African American patients were four times more likely to miss two or more visits [odds ratio (OR), 4.17; P = 0.0026] than others; estimated income <$50 000 was associated with a two-fold increase in missing two or more visits (OR, 2.33; P = 0.035). By identifying at-risk patient populations, healthcare systems can adopt strategies to remove barriers of accessing follow-up care.

Race Predicts Unsuccessful Healing of Osteochondritis Dissecans in the Pediatric Knee

The purpose of this study was to evaluate the effect of race, insurance status, and socioeconomic status on successful or unsuccessful healing of osteochondritis dissecans (OCD) lesions in the pediatric knee. The authors retrospectively reviewed patients younger than 18 years who were treated for a knee OCD lesion between 2006 and 2017. Patients were required to have at least 6 months of clinical and radiographic follow-up to be included, unless complete healing was achieved sooner. The primary outcome of interest was healing of the OCD lesion based on radiographic and clinical examination. A total of 204 OCD lesions in 196 patients with a mean follow-up of 15.8±6.4 months were included. The mean age at initial presentation was 12.4±2.8 years. At most recent follow-up, 28 (13.7%) lesions did not show radiographic or clinical evidence of healing. Nonhealing lesions were found in 25.0% of Black children compared with 9.4% of White children (P=.02). After controlling for age, sex, sports participation, lesion size and stability, skeletal maturity, and operative vs nonoperative treatment in a multivariate model, Black children had 6.7 times higher odds of unsuccessful healing compared with their White counterparts (95% CI, 1.1-41.7; P=.04). In this study, Black children with OCD of the knee were significantly less likely to heal than were White patients, even when controlling for numerous other factors in a multivariate model. Although the exact etiology of this finding is unclear, future work should focus on the social, economic, and cultural factors that may lead to disparate outcomes.

Are there racial differences between patients undergoing surgery for shoulder instability? Data from the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability Group

BACKGROUND

The purpose of this study was to identify differences related to race in preoperative and intraoperative findings of patients undergoing operative treatment for shoulder instability.

METHODS

Data from the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort were used. Of 1010 patients, 995 provided race and ethnicity information and were included in the analyses. Demographic characteristics, injury history, radiographic and intraoperative findings, and preoperative patient-reported instability, pain, and function were compared (1) between white and minority patients and (2) in a subgroup analysis between white patients and the 3 largest minority groups. The Distressed Communities Index (DCI) score was recorded for each patient's home ZIP code. Multiple logistic regressions were performed to determine whether models consisting of race/ethnicity, insurance carrier, and/or DCI score were predictive of bone and cartilage loss at the time of surgery.

RESULTS

Compared with white patients, a greater percentage of US minority patients had ≥2 dislocations (68.0% vs. 57.1%, P = .01), which corresponded with more frequent articular cartilage lesions (62.2% vs. 51.0%, P = .007) and increased frequencies of glenoid bone loss > 10% (16.2% vs. 8.7%, P = .03) and Hill-Sachs lesions (68.6% vs. 56.0%, P = .004). Specifically, when compared with white patients, African American and Asian patients showed significantly increased frequencies of glenoid bone loss > 10% (19.7% of African American patients, 18.4% of Asian patients, and 8.9% of white patients; P = .01) and Hill-Sachs lesions (65.6%, 71.7%, and 52.4%, respectively; P = .02). Race was an independent predictor of articular cartilage lesions (P = .04) and the presence of Hill-Sachs lesions (P = .01). A higher DCI score (P = .03) and race (P = .04) were both predictive of having glenoid bone loss > 10%.

CONCLUSION

We found that minority race was associated with increased number of preoperative dislocations and increased frequency of articular cartilage and Hill-Sachs lesions at the time of surgery, and both minority race and an increased DCI score were associated with glenoid bone loss > 10%. Further research is needed to understand the underlying reason for these differences and to optimize care for all patients with shoulder instability.

How Do Race and Insurance Status Affect the Care of Pediatric Anterior Cruciate Ligament Injuries?

OBJECTIVE

To identify associations between race or insurance status and preoperative, intraoperative, and postoperative findings in a large cohort of pediatric anterior cruciate ligament (ACL) reconstructions.

DESIGN

Retrospective cohort study.

SETTING

Division of Orthopaedics at an urban tertiary care children's hospital.

PATIENTS

915 pediatric (<21) patients undergoing primary ACL reconstruction between January 2009 and May 2016.

INDEPENDENT VARIABLES

Insurance status and race.

MAIN OUTCOME MEASURES

Delay to surgery, concurrent meniscal injury, sports clearance, postoperative complications, physical therapy, range of motion, and isokinetic strength reduction.

RESULTS

Multivariate analysis revealed a significantly longer delay to surgery for black/Hispanic and publicly insured children compared to their counterparts (P = 0.02 and P = 0.001, respectively). Black/Hispanic patients were more likely to sustain irreparable meniscus tears resulting in meniscectomy than white/Asian patients (odds ratio 2.16, 95% confidence interval, 1.10-2.29, P = 0.01). Black/Hispanic and publicly insured children averaged fewer physical therapy (PT) visits (P < 0.001 for both). Nine months after surgery, black/Hispanic patients had significantly greater strength reduction than white/Asian patients. There were no differences in postoperative complications, including graft rupture, contralateral ACL injury, or new meniscus tear along the lines of race, although privately insured patients were more likely to suffer a graft rupture than publicly insured patients (P = 0.006).

CONCLUSIONS

After ACL rupture, black/Hispanic children and publicly insured children experience a greater delay to surgery. Black/Hispanic patients have more irreparable meniscus tears and less PT visits. Black/Hispanic patients have greater residual hamstrings and quadriceps weakness 9 months after surgery.

Inequalities in Pediatric Fracture Care Timeline Based on Insurance Type

INTRODUCTION

Socioeconomic and insurance status are often linked with limited access to health care. Despite several government-funded projects aimed at curtailing these barriers, pediatric orthopaedic patients continue to experience delays in receiving timely care for fracture treatments. This delay has been well-identified within the orthopaedic literature but, to our knowledge, has never been characterized based on timeline. Thus, the goal of this study is to evaluate the role of ethnicity, socioeconomic status, and insurance type on the timeline of pediatric patients to obtain orthopaedic care within our community.

METHODS

Pediatric patients presenting to our clinic for the treatment of one of 21 most common fractures were included. Patient demographics and the timeline of patient care were collected by retrospective chart review.

RESULTS

Government-funded insurance accounted for 60.6% of the 413 patients. These patients experienced significant (P < 0.001) delays in access to care when compared with commercial insurance patients; the time between injury and referral as well as the overall time from injury to orthopaedic evaluation was 2.8 and twofold greater at 4.4 days and 9.2 days, respectively. A strong correlation was established between income levels and insurance type.

DISCUSSION

Pediatric patients with a lower socioeconomic status are more likely to rely on government-funded insurance and experience delays in fracture evaluation.

Association Between Government Health Insurance Status and Physical Activity in American Youth

BACKGROUND

Health insurance plans provide health programming access and affect physical activity levels in American youth, leading to health disparities in American children. The primary purpose of the current study was to investigate the relationship between health insurance status and physical activity level in American youth.

METHODS

A national, United States census weighted cross-sectional survey was performed analyzing 2002 noninstitutionalized children living in the United States between the ages of 10 to 18 years, equally split by age and sex, with state of residency and race/ethnicity proportional to the 2010 census distribution. Multiple linear regression was performed to investigate the relationship between insurance status and activity level (measured by HSS Pedi-FABS activity score) while controlling for relevant demographic and socioeconomic covariables.

RESULTS

HSS Pedi-FABS activity scores were normally distributed with a mean of 15.4±8.5 points (of 30 possible points). Patients with an insurance status of "government/Medicaid," "other," or "none" each demonstrated significantly lower physical activity scores (14.2±8.5 vs. 13.6±9.0 vs. 10.1±8.5) than children with private insurance (16.5±8.2) (one-way ANOVA with Dunnett-adjusted pairwise comparisons, P<0.001), which remained statistically significant while controlling for Area Deprivation Index, age, gender, race/ethnicity, and Body Mass Index (β=-1.8, P<0.001).

CONCLUSIONS

Government/Medicaid health insurance status and lack of health care coverage are associated with low levels of physical activity in American children, even while controlling for socioeconomic confounders. Collaborative work between health care providers and community/ school-based programs may be a reasonable approach to expanding access to recreation, organized sports, and physical activity for publicly and uninsured children.

Large observational study on risks predicting emergency department return visits and associated disposition deviations

Objective

A common emergency department (ED) patient care outcome metric is 72-hour ED return visits (EDRVs). Risks predictive of EDRV vary in different studies. However, risk differences associated with related versus unrelated EDRV and subsequent EDRV disposition deviations (EDRVDD) are rarely addressed. We aim to compare the potential risk patterns predictive of related and unrelated EDRV and further determine those potential risks predictive of EDRVDD.

Methods

We conducted a large retrospective observational study from September 1, 2015 through June 30, 2016. ED Patient demographic characteristics and clinical metrics were compared among patients of 1) related; 2) unrelated; and 3) no EDRVs. EDRVDD was defined as obvious disposition differences between initial ED visit and return visits. A multivariate multinomial logistic regression was performed to determine the independent risks predictive of EDRV and EDRVDD after adjusting for all confounders.

Results

A total of 63,990 patients were enrolled; 4.65% were considered related EDRV, and 1.80% were unrelated. The top risks predictive of EDRV were homeless, patient left without being seen, eloped, or left against medical advice. The top risks predictive of EDRVDD were geriatric and whether patients had primary care physicians regardless as to whether patient returns were related or unrelated to their initial ED visits.

Conclusion

Over 6% of patients experienced ED return visits within 72 hours. Though risks predicting such revisits were multifactorial, similar risks were identified not only for ED return visits, but also for return ED visit disposition deviations.

The association between patient education level and economic status on outcomes following surgical management of (fracture) non-union

BACKGROUND

Socioeconomic disparities are an inherent and currently unavoidable aspect of medicine. Knowledge of these disparities is an essential component towards medical decision making, particularly among an increasingly diverse population. While healthcare disparities have been elucidated in a wide variety of orthopaedic conditions and management options, they have not been established among patients who present for treatment of an ununited fracture. The purpose of this study is to answer the following questions: 1) Following surgical management of (fracture) non-unions, are there differences in outcomes between differing ethnic groups? 2) Following surgical management of (fracture) non-unions, are there differences in outcomes between patients with differing education levels? 3) Following surgical management of (fracture) non-unions, are there differences in outcome between patients with differing incomes?

METHODS

Between September 2004 and December 2017, operatively treated patients who presented with a long bone fracture non-union were prospectively followed. These patients presented with a variety of fracture non-unions that underwent surgical intervention. Sociodemographic factors were recorded at presentation. Long-term outcomes were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, post-operative complications and physical exam at latest follow up. The SMFA is a 46-item questionnaire, assessing patient functional and emotional response to musculoskeletal ailments.

RESULTS

Three-hundred-twenty-nine patients met inclusion criteria. Patients with a lower education had worse long-term functional outcomes (P < 0.001) and increased pain scores (P = 0.002) at latest follow-up. Patients who made less than $50,000 annually had worse long-term functional outcomes (P = 0.002) and reported higher pain scores (P = 0.003) following surgical management of (fracture) non-unions. Multiple linear regression demonstrated education level to be an independent predictor of long-term functional outcomes following surgical management of (fracture) non-unions (B= -0.154, 95% Confidence Interval [CI]=-10.96 to -1.26, P = 0.014). No differences existed in outcomes or pain scores between those of different ethnic groups. No differences existed regarding post-operative complications and time to union between patients of different ethnic groups, educational levels and income status.

CONCLUSION

Patients with lower education levels and individuals who make less than $50,000 annually have worse functional outcomes following surgical management of (fracture) non-unions. Orthopaedic trauma surgeons should therefore be aware of these disparities, and consider early interventions aimed at optimizing patient recovery in these subsets.

Health Care Access Barriers Bring Children to Emergency Rooms More Frequently: A Representative Survey

Children may visit the emergency department (ED) regularly in part because they and their caregivers may be experiencing barriers to appropriate and timely pediatric care. However, assessing the wide range of potential barriers to access to care that children and their caregivers may experience is often a challenge. The objective of this study was to assess the barriers to pediatric health care reported by caregivers and to examine the association between those reported barriers to care with the frequency of children's ED visits in the past 12 months. Assessment of ED utilization and access to care barriers was made through a telephone interview survey conducted as part of a broader Community Health Needs Assessment in 2015. A weighted community sample of adult caregivers (N = 1057) of children between the ages of 0-17 residing in Miami-Dade, Broward, and Palm Beach counties, Florida were contacted. This study found that multiple ED visits (≥2 vs. 0) in the past 12 months by a child were most strongly associated with access to care barriers attributed to language and culture (relative risk [RR] = 2.51), trouble finding a doctor (RR = 1.86), scheduling an appointment (RR = 1.68), and transportation access (RR = 1.73). These findings suggest that access to care barriers experienced by households may exacerbate the risk of a child experiencing repeated visits to the ED in a year. Findings are discussed further in the context of actionable population health management strategies to reduce risk of frequent ED utilization by children.

Risk Factors Associated With Emergency Department Return Visits Following Trauma System Discharge

OBJECTIVES

Little evidence exists in the pediatric trauma literature regarding what factors are associated with re-presentation to the hospital for patients discharged from the emergency department (ED).

METHODS

This was a retrospective cohort study of trauma system activations at a pediatric trauma center from June 30, 2007, through June 30, 2013, who were subsequently discharged from the ED or after a brief inpatient stay. Returns within 30 days were reviewed. χ, Student t test, and univariate logistical regression were used to compare predictive factors for those returning and not.

RESULTS

One thousand eight hundred sixty-three patient encounters were included in the cohort. Seventy-two patients (3.9%) had at least 1 return visit that was related to the original trauma activation. Age, sex, language, race/ethnicity, ED length of stay, arrival mode, level of trauma activation, and transfer from an outside hospital did not vary significantly between the groups. Patients with public insurance were almost 2 times more likely to return compared with those with private insurance (odds ratio, 1.92; 95% confidence interval, 1.11-3.35). Income by zip code was associated with the risk of a return visit, with patients in neighborhoods at less than the 50th percentile income twice as likely to return to the ED (odds ratio, 2.15; 95% confidence interval, 1.30-3.54).

CONCLUSIONS

Patients with public insurance and those from low-income neighborhoods were significantly more likely to return to the ED after trauma system activation. These data can be used to target interventions to decrease returns in high-risk trauma patients.

Increasing rates of surgical treatment for paediatric diaphyseal forearm fractures: a National Database Study from 2000 to 2012

FOREARM

Purpose fractures are one of the most commonly sustained injuries in children and are often treated non-operatively. The purpose of this study was to estimate the rate of inpatient surgical treatment of paediatric forearm fractures over time using a large, publicly available, national database.

METHODS

The Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) was evaluated between 2000 and 2012. Forearm fractures and surgeries were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) diagnosis and procedure codes. Univariable and multivariable logistic regression were used to determine variables associated with greater proportion of surgical treatment. All statistical analyses were performed using SAS statistical software v.9.4 (SAS Institute Inc., Cary, NC, USA). Statistical significance was set at p < 0.05.

RESULTS

The database identified 30 936 forearm fracture admissions. Overall, 19 837 of these patients were treated surgically (64.12%). The percentage of patients treated with surgery increased from 59.3% in 2000 to 70.0% in 2012 (p < 0.001). Multivariable regression analysis found increased age (p < 0.001), more recent year (p < 0.001), male gender (p = 0.003) and admission to a children's hospital (p < 0.001) were associated with an increased proportion of patients receiving surgical treatment. Medicaid payer status was associated with a lower proportion of surgical treatment (p < 0.001).

CONCLUSIONS

The rate of operative treatment for paediatric forearm fractures admitted to the hospital increased over time. Increased surgical rates were associated with older age, male gender, treatment at a children's hospital and non-Medicaid insurance status.

Socioeconomic Factors Are Associated With Trends in Treatment of Pediatric Femoral Shaft Fractures, and Subsequent Implant Removal in New York State

BACKGROUND

Disparities exist in access to outpatient pediatric orthopaedic care. The purpose of this study was to assess whether disparities also exist in elective pediatric orthopaedic surgical procedures such as implant removal, and to determine which demographic and socioeconomic factors may be associated with differences in treatment.

METHODS

Children aged 7 to 18 inclusive who sustained femoral shaft fractures between the years 1997 and 2010 were identified in the New York State SPARCS database. Patient age, sex, race/ethnicity, insurance status, education, and poverty were identified. Factors associated with the method of fracture treatment were assessed through multivariate regression analysis. The subset of patients that received internal fixation were followed up until 2011 inclusive for implant removal. Factors associated with implant removal were assessed using a Cox proportional hazards survival analysis (time to implant removal).

RESULTS

Of the 3220 closed femoral shaft fractures identified, 2609 (81%) were treated with internal fixation, 9 (0.3%) had open treatment without implants, 203 (6.3%) were treated with external fixation, and 399 (12.4%) with closed methods. Patients with No Fault/Accident insurance by No Fault/Accident insurance were more likely to undergo internal fixation compared with patients with private insurance (P<0.001). Of the 3220 patients, 2572 were included in the implant removal subanalysis. Implant removal was performed in 725 (28.2%) patients. In the multivariate model, patients were more likely to undergo removal if they were younger (P<0.001), white [vs. black (P<0.001), vs. Hispanic (P=0.035), vs. other (P=0.001)], and lived in neighborhoods with less poverty (P=0.016). Insurance status was not a statistically significant predictor of implant removal.

CONCLUSIONS

There is an association between implant removal and younger age, white race, and higher socioeconomic status in children. Awareness of these disparities should prompt further evaluation of causation, whether it be from lack of evidence-based guidelines for implant removal, surgeon bias, variations in reimbursement, or disparities in access to care. Further study is recommended to better elucidate the indications for implant removal in children and the causes for the disparities identified here.

The Impact of Payer Source on Trauma Outcomes in a Pediatric Population

OBJECTIVES

Determine if there were differences in conclusions drawn regarding disparities in trauma outcomes based on literature-derived payer source definitions in a pediatric population.

PATIENTS AND METHODS

Retrospective registry review of admitted pediatric trauma patients (≤17 years of age) at a level II pediatric trauma facility. Eligible patients were categorized into 3 payer source definitions: definition 1: commercially insured, Medicaid, uninsured; definition 2: insured, uninsured; definition 3: commercially insured, underinsured. Logistic regression was used to determine the influence of payer source on outcomes.

RESULTS

Payer source was not significant in definition 1, 2, or 3 for intensive care unit length of stay (LOS), hospital LOS, medical consults, or mortality. For hospital disposition, payer source was significant in definition 1, the uninsured were 90% less likely than commercially insured to be discharged to continued care. In definition 2, the uninsured were 88% less likely than insured to be discharged to continued care. In definition 3, the underinsured were 57% less likely than commercially insured to be discharged to continued care.

CONCLUSIONS

Differences between the literature-derived definitions were not observed and therefore conclusions drawn did not differ across definitions. The investigation demonstrated payer source was not associated with in-hospital outcomes (intensive care unit LOS, hospital LOS, medical consults, and mortality), but was with posthospital outcomes. Findings warrant future examinations on the categorization of payer source in pediatric patients and hospital disposition to gain a greater understanding of disparities related to payer source in pediatric trauma, specifically in terms of posthospital care.

Medial Epicondyle Fractures in Children and Adolescents: Shifting Care from General Hospitals to Children's Hospitals?

OBJECTIVES

To determine if there is a shift in the treatment of children with medial epicondyle fractures toward children's hospitals, and to explore potential confounders of any observed effect.

STUDY DESIGN

The Healthcare Cost and Utilization Project Kids' Inpatient Database was used to examine the epidemiology of medial epicondyle fractures, particularly with attention to whether they were admitted to a general hospital or a children's hospital (defined as free-standing children's hospitals, specialty children's hospitals, and children's units within general hospitals). Age and insurance payer status were also collected and evaluated as potential confounders.

RESULTS

The proportion of medial epicondyle hospital discharges from children's hospitals increased (from 29%-46%; P < .001), and the proportion of discharges from general hospitals declined over the study period (from 71%-42%; P < .001). Age and insurance payer status both remained consistent throughout the study period and did not contribute to this finding.

CONCLUSIONS

This study demonstrates an increase in the proportion of discharges for pediatric medial epicondyle fractures from children's hospitals. Although this finding is likely multifactorial, it may represent increasing subspecialization and increasing medical liability when treating children. Children's hospitals should identify those conditions which will continue to increase in number and consider constructing clinical pathways in order to optimize delivery of care and resource utilization.

Low Vitamin D Levels in Children with Fractures: a Comparative Cohort Study

BACKGROUND

The currently accepted ranges for "normal" serum vitamin D have recently been challenged in adults on the basis that healthy bone metabolism requires higher levels of vitamin D than previously thought.

PURPOSE

The purpose of this study was to evaluate whether a new "biologically based" classification based on 25(OH)vitamin D levels that invoke an endocrine biomarker response (<20 ng/mL for deficiency and <32 ng/mL for insufficiency) is more appropriate for children with fractures than historical criteria.

METHODS

Serum 25(OH)vitamin D levels were collected from 58 children with acute low-energy fractures from an outpatient orthopedic clinic from 2009 to 2012. These vitamin D levels were compared with a cohort of 103 children with chronic kidney disease (CKD) from an adjacent clinic, a condition with acknowledged low levels of vitamin D. Then, the prevalence of vitamin D sufficiency in the fracture cohort was evaluated and compared using both historical guidelines and newer biologically based criteria.

RESULTS

25(OH)vitamin D levels in the fracture cohort did not differ from levels in the CKD cohort (27.5 vs. 24.6 ng/mL) indicating a similar distribution of vitamin D levels. This finding was consistent when controlling for significant covariables using linear regression analyses. In the fracture cohort, there was a discrepancy between historical and biologically based criteria in 64% of children.

CONCLUSIONS

The results of the current study suggest that fracture patients are more frequently vitamin D deficient than previously thought. This finding is more readily apparent when newer biologically based criteria for vitamin D sufficiency are used.
