More problems, more money: Identifying and predicting high-cost rescue after colorectal surgery.

Background: Successful rescue after elective surgery is associated with increased healthcare costs, but costs vary widely. Treating all rescue events the same may overlook targeted opportunities for improvement. The purpose of this study was to predict high-cost rescue after elective colorectal surgery. Methods: We identified adult patients in the National Inpatient Sample (2016-2021) who underwent elective colectomy or proctectomy. Rescued patients were defined as those who underwent additional major procedures. Three groups were stratified: 1) uneventful recovery; 2) Low-cost rescue; 3) High-cost rescue. Multivariable Poisson regression was used to identify preoperative clinical predictors of high-cost versus low-cost rescue. Results: We identified 448,590 elective surgeries, and rescued patients composed 4.8 %(21,635) of the total sample. The median increase in costs in rescued patients was $25,544(p < 0.001). Median total inpatient costs were $95,926 in the most expensive rescued versus $34,811 in the less expensive rescued versus $16,751 in the uneventfully discharged(p < 0.001). When comparing the secondary procedures between the less expensive and most expensive rescued groups, the most expensive had an increased proportion of reoperation (73.4 % versus 53.0 %,p < 0.001). When controlling for other factors and stratification by congestive heart failure due to an interaction effect, a reoperation was independently associated with high-cost rescue (RR with CHF = 3.29,95%CI:2.69-4.04; RR without CHF = 2.29,95%CI:1.97-2.67). Conclusions: High-cost rescue after colorectal surgery is associated with disproportionately greater healthcare utilization and reoperation. For cost-conscious care, preemptive strategies that reduce reoperation-related complications can be prioritized.

The association between severe maternal morbidity and mortality and race/ethnicity with community type in Maryland.

BACKGROUND: Severe maternal morbidity and mortality are increasing in the United States with continued healthcare disparities among Non-Hispanic Black women. However, there is sparse data on the disparities of severe maternal morbidity and mortality by race/ethnicity as it relates to community type. OBJECTIVE: To determine whether residing in rural communities increases the racial/ethnic disparities in severe maternal morbidity and mortality. DESIGN: This study is a cross-sectional analysis of women admitted for delivery from 2015 to 2020. A total of 204,140 adults who self-identified as women, were admitted for delivery, who resided in Maryland, and were between the ages 15 and 54 were included in our analysis. Community type was defined as either rural or urban. METHODS: A multivariable logistic regression, which included an interaction term between race/ethnicity and community type, was used to assess the effect of community type on the relationship between race/ethnicity and severe maternal morbidity and mortality. Data were obtained from the Maryland Health Service Cost Review Commission database. The primary outcome was a composite, binary variable of severe maternal morbidity and mortality. Exposures of interest were residence in either rural or urban counties in Maryland and race/ethnicity. RESULTS: Our study found that after adjusting for confounders, odds of severe maternal morbidity and mortality were 65% higher in Non-Hispanic Black women (odds ratio 1.65, 95% confidence interval: 1.46-1.88, p < 0.001) and 54% higher in Non-Hispanic Asian women (odds ratio 1.54, 95% confidence interval: 1.24-1.90, p < 0.001) compared to Non-Hispanic White women. The interaction term used to determine whether community type modified the relationship between race/ethnicity and severe maternal morbidity and mortality was not statistically significant for any race/ethnicity (Non-Hispanic Black women, p = 0.60; Non-Hispanic Asian women, p = 0.91; Hispanic women, p = 0.15; Other/Unknown race/ethnicity, p = 0.54). CONCLUSION: Although our study confirmed the known disparities in maternal outcomes by race/ethnicity, we found that residing in rural communities did not increase racial/ethnic disparities.

The impact of a statewide payment reform on transcatheter aortic valve replacement (TAVR) utilization and readmissions.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an increasingly used but relatively expensive procedure with substantial associated readmission rates. It is unknown how cost-constrictive payment reform measures, such as Maryland's All Payer Model, impact TAVR utilization given its relative expense. This study investigated the impact of Maryland's All Payer Model on TAVR utilization and readmissions among Maryland Medicare beneficiaries. METHODS: This was a quasi-experimental investigation of Maryland Medicare patients undergoing TAVR between 2012 and 2018. New Jersey data were used for comparison. Longitudinal interrupted time series analyses were used to study TAVR utilization and difference-in-differences analyses were used to investigate post-TAVR readmissions. RESULTS: During the first year of payment reform (2014), TAVR utilization among Maryland Medicare beneficiaries dropped by 8% (95% confidence interval [CI]: -9.2% to -7.1%; p < 0.001), with no concomitant change in TAVR utilization in New Jersey (0.2%, 95% CI: 0%-1%, p = 0.09). Longitudinally, however, the All Payer Model did not impact TAVR utilization in Maryland compared to New Jersey. Difference-in-differences analyses demonstrated that implementation of the All Payer Model was not associated with significantly greater declines in 30-day post-TAVR readmissions in Maryland versus New Jersey (-2.1%; 95% CI: -5.2% to 0.9%; p =0.1). CONCLUSIONS: Maryland's All Payer Model resulted in an immediate decline in TAVR utilization, likely a result of hospitals adjusting to global budgeting. However, beyond this transition period, this cost-constrictive reform measure did not limit Maryland TAVR utilization. In addition, the All Payer Model did not reduce post-TAVR 30-day readmissions. These findings may help inform expansion of globally budgeted healthcare payment structures.

National emergency department trends for endogenous endophthalmitis: an increasing public health challenge.

BACKGROUND/OBJECTIVE: To characterize incidence rates and identify risk factors for admission and mortality in patients with endogenous endophthalmitis (EE) in the United States (US). SUBJECTS/METHODS: Patients with EE were identified using the Nationwide Emergency Department (NEDS) Database from 2006 to 2017 in this cross-sectional study. Subjects were required to have diagnoses of both endophthalmitis and septicaemia using contemporary International Classification of Diseases diagnosis codes. Incidence rates, mortality rates and demographics were evaluated. Risk factors for admission and mortality were identified using weighted logistic regression analysis. RESULTS: A total of 6400 patients with EE were identified. Incidence increased from 0.10 (95% confidence interval [CI]: 0.07-0.12) per 100,000 in the US population in 2006 to 0.25 (95% CI: 0.21-0.30) in 2017 (p < 0.05). Most were female (55.4%), insured with Medicare (53.5%), were in the first income quartile earnings (29.3%) [bottom 25% income bracket], lived in the South (40.5%), and presented to metropolitan teaching hospitals (66.6%). Mortality increased from 8.6% (95% CI: 3.8-18.3%) in 2006 to 13.8% (95% CI: 9.7-19.2%) in 2017 (p = 0.94). Factors predicting admission included older age (odds ratio [OR] 32.59; [95% CI 2.95-359.78]) and intravenous drug use (OR 14.90 [95% CI: 1.67-133.16]). Factors associated with increased mortality included: human immunodeficiency virus infection/immune deficiencies (OR 2.58 [95% CI: 1.26-5.28]), heart failure (OR 2.12 [95% CI: 1.47-3.05]), and hepatic infections/cirrhosis (OR 1.89 [95% CI: 1.28-2.79]). Pneumonia and renal/urinary tract infections (UTI) were associated with both increased hospital admission [(pneumonia OR 9.64 (95% CI: 1.25-74.35, p = 0.030), renal/UTI OR 4.09 (95% CI: 1.77-9.48)] and mortality [(pneumonia OR 1.64 (95% CI: 1.17-2.29, p = 0.030), renal/UTI OR 1.87 (95% CI: 1.18-2.97)]. Patients with diabetes mellitus (DM) had decreased odds ratio for mortality (OR 0.49 [95% CI: 0.33-0.73]). CONCLUSION: EE has increased in incidence throughout US. The two systemic factors that conferred both an increase in mortality and admission were pneumonia, and renal/UTI. Additional exploration of the potential protective association of DM with decreased mortality in this context is needed.

Factors Associated with Length of Stay and Cost among Pediatric Hospitalizations with a Primary Ophthalmic Diagnosis.

PURPOSE: To investigate factors associated with prolonged length of stay and high cost among pediatric hospitalizations with a primary ophthalmic diagnosis. METHODS: This retrospective, cross-sectional study utilized data on pediatric admissions with a primary ophthalmic diagnosis from the multicenter 2016 Kids' Inpatient Database. Multivariable logistic regression models adjusted for demographic, hospital, and admission characteristics were used to evaluate factors associated with prolonged stay and high cost, defined as exceeding the 75th percentile (>4 days and $12,642, respectively). RESULTS: An estimated 6,811 pediatric hospitalizations with a primary ophthalmic diagnosis in the United States in 2016 were included. On adjusted analysis, a prolonged length of stay was more likely with Medicaid (vs. private insurance, OR = 1.19, 95% CI: [1.02, 1.40], p = .03), non-trauma (vs. trauma, OR = 2.77, 95% CI: [2.12, 3.63], p < .001) and urban teaching hospitals (vs. rural, OR = 3.48, 95% CI: [1.04, 11.69], p = .04). A high cost of stay was more likely with higher income levels (Quartile 3 vs. 1, OR = 1.30, 95% CI: [1.02, 1.67], p = .04; Quartile 4 vs. 1, OR = 1.49, 95% CI: [1.08, 2.05], p = .02), private insurance (vs. Medicaid, OR = 1.26, 95% CI: [1.04, 1.53], p = .02), Western hospitals (vs. South, OR = 2.74, 95% CI: [1.83, 4.12], p < .001), and trauma (vs. non-trauma, OR = 3.29, 95% CI: [2.57, 4.21], p < .001). Children and young adults had higher odds of prolonged stay, while adolescents and young adults had higher odds of high cost compared to toddlers (p < .05 for all). CONCLUSIONS: Additional work addressing the factors associated with higher resource utilization may help promote the delivery of quality inpatient pediatric eye care.

Do Cost Limitations of Extended Prophylaxis After Surgery Apply to Ulcerative Colitis Patients?

BACKGROUND: Colorectal surgery patients with ulcerative colitis are at increased risk of postoperative venous thromboembolism. Extended prophylaxis for thromboembolism prevention has been used in colorectal surgery patients, but it has been criticized for its lack of cost-effectiveness. However, the cost-effectiveness of extended prophylaxis for postoperative ulcerative colitis patients may be unique. OBJECTIVE: This study aimed to assess the cost-effectiveness of extended prophylaxis in postoperative ulcerative colitis patients. DESIGN: A decision analysis compared costs and benefits in postoperative ulcerative colitis patients with and without extended prophylaxis over a lifetime horizon. SETTING: Assumptions for decision analysis were identified from available literature for a typical ulcerative colitis patient's risk of thrombosis, age at surgery, type of thrombosis, prophylaxis risk reduction, bleeding complications, and mortality. MAIN OUTCOME MEASURES: Costs ($) and benefits (quality-adjusted life year) reflected a societal perspective and were time-discounted at 3%. Costs and benefits were combined to produce the main outcome measure, the incremental cost-effectiveness ratio ($ per quality-adjusted life year). Multivariable probabilistic sensitivity analysis modeled uncertainty in probabilities, costs, and disutilities. RESULTS: Using reference parameters, the individual expected societal total cost of care was $957 without and $1775 with prophylaxis (not cost-effective; $257,280 per quality-adjusted life year). Preventing a single mortality with prophylaxis would cost $5 million (number needed to treat: 6134 individuals). Adjusting across a range of scenarios upheld these conclusions 77% of the time. With further sensitivity testing, venous thromboembolism cumulative risk (>1.5%) and ePpx regimen pricing (<$299) were the 2 parameters most sensitive to uncertainty. LIMITATIONS: Recommendations of decision analysis methodology are limited to group decision-making, not an individual risk profile. CONCLUSION: Routine ePpx in postoperative ulcerative colitis patients is not cost-effective. This finding is sensitive to higher-than-average rates of venous thromboembolism and low-cost prophylaxis opportunities. See Video Abstract at http://links.lww.com/DCR/B818. SE APLICAN LAS LIMITACIONES DE COSTOS DE LA PROFILAXIS PROLONGADA DESPUS DE LA CIRUGA A LOS PACIENTES CON COLITIS ULCEROSA: ANTECEDENTES:Los pacientes de cirugía colorrectal con colitis ulcerosa tienen un mayor riesgo de tromboembolismo venoso posoperatorio. La profilaxis extendida para la prevención de la tromboembolia se ha utilizado en pacientes con cirugía colorrectal, aunque ha sido criticada por su falta de rentabilidad. Sin embargo, la rentabilidad de la profilaxis prolongada para los pacientes posoperados con colitis ulcerosa puede ser aceptable.OBJETIVO:Evaluar la rentabilidad de la profilaxis prolongada en pacientes posoperados con colitis ulcerosa.DISEÑO:Un análisis de decisiones comparó los costos y beneficios en pacientes posoperados con colitis ulcerosa con y sin profilaxis prolongada de por vida.AJUSTE:Los supuestos para el análisis de decisiones se identificaron a partir de la literatura disponible para el riesgo de trombosis de un paciente con colitis ulcerosa típica, la edad al momento de la cirugía, el tipo de trombosis, la reducción del riesgo con profilaxis, las complicaciones hemorrágicas y la mortalidad.PRINCIPALES MEDIDAS DE RESULTADO:Los costos ($) y los beneficios (año de vida ajustado por calidad) reflejaron una perspectiva social y se descontaron en el tiempo al 3%. Los costos y los beneficios se combinaron para producir la principal medida de resultado, la relación costo-efectividad incremental ($ por año de vida ajustado por calidad). El análisis de sensibilidad probabilística multivariable modeló la incertidumbre en probabilidades, costos y desutilidades.RESULTADOS:Utilizando parámetros de referencia, el costo total de atención social esperado individual fue de $957 sin profilaxis y $1775 con profilaxis (no rentable; $257,280 por año de vida ajustado por calidad). La prevención de una sola mortalidad con profilaxis costaría $5.0 millones (número necesario a tratar: 6.134 personas). El ajuste en una variedad de escenarios mantuvo estas conclusiones el 77% de las veces. Con más pruebas de sensibilidad, el riesgo acumulado de TEV (>1,5%) y el precio del régimen de ePpx (<$299) fueron los dos parámetros más sensibles a la incertidumbre.LIMITACIONES:Las recomendaciones de la metodología de análisis de decisiones se limitan a la toma de decisiones en grupo, no a un perfil de riesgo individual.CONCLUSIÓN:La profilaxis extendida de rutina en pacientes posoperados con colitis ulcerosa no es rentable. Este hallazgo es sensible a tasas de TEV superiores al promedio y oportunidades de profilaxis de bajo costo. Consulted Video Resumen en http://links.lww.com/DCR/B818.

Racial Disparities Associated With Reinterventions After Elective Endovascular Aortic Aneurysm Repair.

BACKGROUND: There are substantial racial and socioeconomic disparities underlying endovascular abdominal aortic aneurysm repair (EVAR) in the United States. To date, race-based variations in reinterventions following elective EVAR have not been studied. Here, we aim to examine racial disparities associated with reinterventions following elective EVAR in a real-world cohort. MATERIALS AND METHODS: We used the Vascular Quality Initiative EVAR dataset to identify all patients undergoing elective EVAR between January 2009 and December 2018 in the United States. We compared the association of race with reinterventions after EVAR and all-cause mortality using Welch two-sample t-tests, multivariate logistic regression, and Cox proportional hazards analyses adjusting for baseline differences between groups. RESULTS: At median follow-up of 1.1 ± 1.1 y (1.3 ± 1.4 y Black, 1.1 ± 1.1 y White; P = 0.02), a total of 1,164 of 42,481 patients (2.7%) underwent reintervention after elective EVAR, including 2.7% (n = 1,096) White versus 3.2% (n = 68) Black (P = 0.21). Black patients requiring reintervention were more frequently female, more frequently current or former smokers, and less frequently insured by Medicare/Medicaid (P < 0.05). After adjusting for baseline differences, the risk of reintervention after elective EVAR was significantly lower for Black versus White patients (HR 0.74, 95% CI 0.55-0.99; P = 0.04). All-cause mortality was comparable between groups (HR 0.81, 95% CI 0.33-2.00, P = 0.65). CONCLUSIONS: There are significant differences between Black and White patients in the risk of reintervention after elective EVAR in the United States. The etiology of this difference deserves investigation.

Systematic Undercoding of Diagnostic Procedures in National Inpatient Sample (NIS): A Threat to Validity Due to Surveillance Bias.

BACKGROUND AND OBJECTIVES: Health services research often relies on readily available data, originally collected for administrative purposes and used for public reporting and pay-for-performance initiatives. We examined the prevalence of underreporting of diagnostic procedures for acute myocardial infarction (AMI), deep venous thrombosis (DVT), and pulmonary embolism (PE), used for public reporting and pay-for-performance initiatives. METHOD: We retrospectively identified procedures for AMI, DVT, and PE in the National Inpatient Sample (NIS) database between 2012 and 2016. From January 1, 2012, through September 30, 2015, the NIS used the International Classification of Diseases, Ninth Revision (ICD-9) coding scheme. From October 1, 2015, through December 31, 2016, the NIS used the International Classification of Diseases, Tenth Revision (ICD-10) coding scheme. We grouped the data by ICD code definitions (ICD-9 or ICD-10) to reflect these code changes and to prevent any confounding or misclassification. In addition, we used survey weighting to examine the utilization of venous duplex ultrasound scan for DVT, electrocardiogram (ECG) for AMI, and chest computed tomography (CT) scan, pulmonary angiography, echocardiography, and nuclear medicine ventilation/perfusion () scan for PE. RESULTS: In the ICD-9 period, by primary diagnosis, only 0.26% (n = 5930) of patients with reported AMI had an ECG. Just 2.13% (n = 7455) of patients with reported DVT had a peripheral vascular ultrasound scan. For patients with PE diagnosis, 1.92% (n = 12 885) had pulmonary angiography, 3.92% (n = 26 325) had CT scan, 5.31% (n = 35 645) had cardiac ultrasound scan, and 0.45% (n = 3025) had scan. In the ICD-10 period, by primary diagnosis, 0.04% (n = 345) of reported AMI events had an ECG and 0.91% (n = 920) of DVT events had a peripheral vascular ultrasound scan. For patients with PE diagnosis, 2.08% (n = 4805) had pulmonary angiography, 0.63% (n = 1460) had CT scan, 1.68% (n = 3890) had cardiac ultrasound scan, and 0.06% (n = 140) had scan. Small proportions of diagnostic procedures were observed for any diagnoses of AMI, DVT, or PE. CONCLUSIONS: Our findings question the validity of using NIS and other administrative databases for health services and outcomes research that rely on certain diagnostic procedures. Unfortunately, the NIS does not provide granular data that can control for differences in diagnostic procedure use, which can lead to surveillance bias. Researchers and policy makers must understand and acknowledge the limitations inherent in these databases, when used for pay-for-performance initiatives and hospital benchmarking.

Quantifying The Costs of Creating and Maintaining Hemodialysis Access in An All-Payer Rate-Controlled Health System.

OBJECTIVES: The creation and maintenance of durable hemodialysis access is critically important for reducing patient morbidity and controlling overall costs within health systems. Our objective was to quantify the costs associated with hemodialysis access creation and its maintenance over time within a rate-controlled health system where charges equate to payments. METHODS: The Maryland Health Services Cost Review Commission administrative claims database was used to identify patients who underwent first-time access creation from 2012-2020. Patients were identified using CPT codes for access creation, and costs were accrued for the initial encounter and all subsequent outpatient access-related encounters. T-tests and Wilcoxon tests were used to compare reinterventions and access-related costs ($USD) between arteriovenous fistulae (AVF) and arteriovenous grafts (AVG). Multivariable modeling was used to quantify the association of access type with charge variation. RESULTS: Overall, 12,716 patients underwent first-time access creation (69.3% AVF vs. 30.7% AVG). There was no difference in freedom from reintervention between the two access types at any point following creation (HR: 1.03, 95%CI: 0.97-1.10); however, AVF were associated with a lower number of cumulative reinterventions (1.50 vs. 2.24) compared to AVG (P<0.0001). AVF was associated with lower overall costs in the year of creation ($9,388 vs. $13,539, P<0.0001), a difference that remained significant over the subsequent 3 years. The lower costs associated with AVF were present both in the costs associated with creation and subsequent maintenance. On multivariable analysis, AVF was associated with a $3,557 reduction in total access-related costs versus AVG (95%CI -$3828, -3287). CONCLUSION: AVF require fewer interventions and are associated with lower costs at placement and over the first three years of maintenance compared to AVG. The use of AVF for first-time hemodialysis access represents an opportunity for healthcare savings in appropriately selected patients with a high preoperative likelihood of AVF maturation.

Geographical socioeconomic disadvantage is associated with adverse outcomes following major amputation in diabetic patients.

OBJECTIVE: Socioeconomic disadvantage is a known predictor of adverse outcomes and amputation in patients with diabetes. However, its association with outcomes after major amputation has not been described. Here, we aimed to determine the association of geographic socioeconomic disadvantage with 30-day readmission and 1-year reamputation rates among patients with diabetes undergoing major amputation. METHODS: Patients from the Maryland Health Services Cost Review Commission Database who underwent major lower extremity amputation with a concurrent diagnosis of diabetes mellitus between 2015 and 2017 were stratified by socioeconomic disadvantage as determined by the area deprivation index (ADI) (ADI1 [least deprived] to ADI4 [most deprived]). The primary outcomes were rates of 30-day readmission and 1-year reamputation, evaluated using multivariable logistic regression models and Kaplan-Meier survival analyses. RESULTS: A total of 910 patients were evaluated (66.0% male, 49.2% Black), including 30.9% ADI1 (least deprived), 28.6% ADI2, 19.1% ADI3, and 21.2% ADI4 (most deprived). After adjusting for differences in baseline demographic and clinical factors, the odds of 30-day readmission was similar among ADI groups (P > .05 for all). Independent predictors of 30-day readmission included female sex (odds ratio [OR], 1.45), Medicare insurance (vs private insurance; OR, 1.76), and peripheral artery disease (OR, 1.49) (P < .05 for all). The odds of 1-year reamputation was significantly greater among ADI4 (vs ADI1; OR, 1.74), those with a readmission for stump complication or infection/sepsis (OR, 2.65), and those with CHF (OR, 1.53) or PAD (OR, 1.59) (P < .05 for all). CONCLUSIONS: Geographic socioeconomic disadvantage is independently associated with 1-year reamputation, but not 30-day readmission, among Maryland patients undergoing a major amputation for diabetes. A directed approach at improving postoperative management of chronic disease progression in socioeconomically deprived patients may be beneficial to reducing long-term morbidity in this high-risk group.

The Direct Healthcare Cost of Stargardt Disease: A Claims-Based Analysis.

Purpose: Stargardt disease (SD) is the most common juvenile macular degeneration and a leading cause of uncorrectable childhood blindness. The progressive and incurable nature of this chronic condition entails a long-term financial burden on affected individuals. The economic costs of SD have not been characterized in detail, so we aimed to estimate the direct healthcare cost of SD.Methods: Outpatient administrative claims data (2010-2014) for patients with SD were analyzed from the IBM® MarketScan® Commercial Claims and Encounters Database. Two comparison groups were selected: nonexudative age-related macular degeneration (AMD) and bilateral sensorineural hearing loss (SHL). Gross median payments per year of insurance coverage were calculated.Results: A total of 472,428 patients were analyzed (5,015 SD, 369,750 SHL and 97,663 AMD patients respectively). The payment per year of insurance coverage for SD (median: 105.58 USD, IQR: 50.53 USD-218.71 USD) was higher than that of SHL (median: 51.01 USD, IQR: 25.66 USD-121.66 USD, p < .001) and AMD (median: 76.20 USD, IQR: 38.00 USD-164.86 USD, p < .001). When adjusted for age, sex, year of first service, and type of benefit plan, the annual payment for SD was 47.83 USD higher than SHL (p < .001) and 17.34 USD higher than AMD (p < .001).Conclusions: There is a significant direct healthcare cost associated with SD. The annual per-patient cost of SD was higher than SHL, another condition that causes sensory impairment in people of all ages, and nonexudative AMD which causes a similar pattern of visual loss that typically begins later in life. The total lifetime per-patient cost of SD may exceed that of nonexudative AMD.

Persistent Opioid Use After Open Aortic Surgery: Risk Factors, Costs, and Consequences.

BACKGROUND: The incidence and financial impact of persistent opioid use (POU) after open aortic surgery is undefined. METHODS: Insurance claim data from opioid-naïve patients who underwent aortic root replacement, ascending aortic replacement, or transverse arch replacement from 2011 to 2017 were evaluated. POU was defined as filling an opioid prescription in the perioperative period and between 90 and 180 days postoperatively. Postoperative opioid prescriptions, emergency department visits, readmissions, and health care costs were quantified. Multivariable logistic regression identified risk factors for POU, and quantile regression quantified the impact of POU on postoperative health care costs. RESULTS: Among 3240 opioid-naïve patients undergoing open aortic surgery, 169 patients (5.2%) had POU. In the univariate analysis, patients with POU were prescribed more perioperative opioids (375 vs 225 morphine milligram equivalents, P < .001), had more emergency department visits (45.6% vs 25.4%, P < .001), and had significantly higher health care payments in the 6 months postoperatively ($10,947 vs $7223, P < .001). Independent risk factors for POU in the multivariable logistic regression included preoperative nicotine use and more opioids in the first perioperative prescription (all P < .05). After risk adjustment, POU was associated with a $2439 increase in total health care costs in the 6 months postoperatively. CONCLUSIONS: POU is a challenge after open aortic operations and can have longer-term impacts on health care payments and emergency department visits in the 6 months after surgery. Strategies to reduce outpatient opioid use after aortic surgery should be encouraged when feasible.

Is Geographic Socioeconomic Disadvantage Associated with the Rate of THA in Medicare-aged Patients?

BACKGROUND: Disparities in THA use may lead to inequitable care. Prior research has focused on disparities based on individual-level and isolated socioeconomic and demographic variables. To our knowledge, the role of composite, community-level geographic socioeconomic disadvantage has not been studied in the United States. As disparities persist, exploring the potential underlying drivers of these inequities may help in developing more targeted recommendations on how to achieve equitable THA use. QUESTIONS/PURPOSES: (1) Is geographic socioeconomic disadvantage associated with decreased THA rates in Medicare-aged patients? (2) Do these associations persist after adjusting for differences in gender, race, ethnicity, and proximity to hospitals performing THA? METHODS: In a study with a cross-sectional design, using population-based data from five-digit ZIP codes in Maryland, USA, from July 1, 2012 to March 31, 2019, we included all inpatient and outpatient primary THAs performed in individuals 65 years of age or older at acute-care hospitals in Maryland, as reported in the Health Services Cost Review Commission database. This database was selected because it provided the five-digit ZIP code data necessary to answer our study question. We excluded THAs performed for nonelective indications. We examined the annual rate of THA in our study population for each Maryland ZIP code, adjusted for differences across areas in distributions of gender, race, ethnicity, and distance to the nearest hospital performing THAs. Four hundred fourteen ZIP codes were included, with an overall mean ± SD THA rate of 371 ± 243 per 100,000 persons 65 years or older, a rate similar to that previously reported in individuals aged 65 to 84 in the United States. Statistical significance was assessed at α = 0.05. RESULTS: THA rates were higher in more affluent areas, with the following mean rates per 100,000 persons 65 years or older: 422 ± 259 in the least socioeconomically disadvantaged quartile, 339 ± 223 in the second-least disadvantaged, 277 ± 179 in the second-most disadvantaged, and 214 ± 179 in the most-disadvantaged quartile (p < 0.001). After adjustment for distributions in gender, race, ethnicity, and hospital proximity, we found that geographic socioeconomic disadvantage was still associated with THA rate. Compared with the least-disadvantaged quartile, the second-least disadvantaged quartile had 63 fewer THAs per 100,000 people (95% confidence interval 12 to 114), the second-most disadvantaged quartile had 136 fewer THAs (95% CI 62 to 211), and the most-disadvantaged quartile had 183 fewer THAs (95% CI 41 to 325). CONCLUSION: Geographic socioeconomic disadvantage may be the underlying driver of disparities in THA use. Although our study does not determine the "correct" rate of THA, our findings support increasing access to elective orthopaedic surgery in disadvantaged geographic communities, compared with prior research and efforts that have studied and intervened on the basis of isolated factors such as race and gender. Increasing access to orthopaedic surgeons in disadvantaged neighborhoods, educating physicians about when surgical referral is appropriate, and educating patients from these geographic communities about the risks and benefits of THA may improve equitable orthopaedic care across neighborhoods. Future studies should explore disparities in rates of appropriate THA and the role of density of orthopaedic surgeons in an area. LEVEL OF EVIDENCE: Level III, therapeutic study.

Characteristics of Orbital Floor Fractures in the United States from 2006 to 2017.

PURPOSE: To examine the incidence, characteristics, and economic burden of orbital floor fractures in the United States. DESIGN: Retrospective, longitudinal study of the Nationwide Emergency Department Sample (NEDS). PARTICIPANTS: Patients in the Emergency Department (ED). METHODS: The NEDS, a representative sample of all hospital-based EDs in the US, was used to identify and describe ED visits with a primary diagnosis of orbital floor fracture from 2006 to 2017. Linear regression was used to estimate the trends in annual incidence and inflation-adjusted ED charges. Logistic regression was used to assess variables associated with inpatient admission. MAIN OUTCOME MEASURES: Incidence, injury mechanisms, demographics, clinical characteristics, disposition, and economic burden. RESULTS: From 2006 to 2017, there were an estimated 350 379 ED visits in the US with a primary diagnosis of orbital floor fracture. The incidence increased by 47% over the study period (P < 0.001): from 7.7 (95% confidence interval [CI], 6.9-8.5) to 11.3 (95% CI, 10.0-12.6) per 100 000 population. The majority were male (67%), aged 21 to 44 years (46%), and from low-income households (32%). The most common cause was assault (43%), which was most frequent in young adults (65%) and increased modestly over time (3.5 to 4.5 per 100 000 population; P = 0.02). The second most common cause was falls (26%), most frequent in patients aged ≥65 years (86%) and more than doubled over time (1.6 to 3.5 per 100 000 population; P < 0.001). The rate of inpatient admission was 14%, with a higher likelihood for patients aged ≥65 years (odds ratio [OR], 2.21; 95% CI, 1.99-2.46; P < 0.001) and falls (OR, 1.54; 95% CI, 1.27-1.86; P < 0.001). The total inflation-adjusted ED charges over the study period exceeded $2 billion, with the mean charge per visit increasing 48% (P < 0.001): from $5881 (95% CI, 5499-6263) to $8728 (95% CI, 8074-9382). CONCLUSIONS: Orbital floor fractures are becoming an increasingly common and costly injury in the United States. Preventive strategies aimed at reducing assault and falls will be crucial to mitigate the burden of orbital floor fractures on the healthcare system.

Persistent Racial and Sex Disparities in Outcomes After Coronary Artery Bypass Surgery: A Retrospective Clinical Registry Review in the Drug-eluting Stent Era.

OBJECTIVE: The purpose of this study was to assess the temporal trends in 30-day mortality by race group for patients undergoing coronary artery bypass grafting (CABG) between 2011 and 2018 and to investigate the effect of race and sex on postoperative outcomes after CABG. SUMMARY BACKGROUND DATA: Cardiovascular diseases remain a leading cause of death in the United States with studies demonstrating increased morbidity and mortality for black and female patients undergoing surgery. In the post drug-eluting stent era, studies of racial disparities CABG are outdated. METHODS: We performed a retrospective analysis of the Society for Thoracic Surgeons database for patients undergoing CABG between 2011 and 2018. Primary outcome was 30-day mortality. Secondary outcomes included postoperative length of stay, surgical site infection, sepsis, pneumonia, stroke, reoperation, reintervention, early extubation, and readmission. RESULTS: The study population was comprised of 1,042,506 patients who underwent isolated CABG between 2011 and 2018. Among all races, Black patients had higher rates of preoperative comorbidities. Compared with White patients, Black patients had higher overall mortality (2.76% vs 2.19%, P < 0.001). On univariable regression, Black patients had higher rates of death, infection, pneumonia, and postoperative stroke compared to White patients. On multivariable regression, Black patients had higher odds of 30-day mortality compared to white patients [odds ratio (OR) = 1.11, 95% confidence interval (CI) 1.05-1.18]. Similarly, female patients had higher odds of death compared to males (OR = 1.26, 95% CI 1.21-1.30). CONCLUSIONS: In the modern era, racial and sex disparities in mortality and postoperative morbidity after coronary bypass surgery persist with Black patients and female patients consistently experiencing worse outcomes than White male patients. Although there may be unknown or underappreciated biological mechanisms at play, future research should focus on socioeconomic, cultural, and multilevel factors.

Male breast cancer: a closer look at patient and tumor characteristics and factors that affect survival using the National Cancer Database.

OBJECTIVE: To comprehensively describe the tumor and clinical characteristics of breast cancer in a cohort of male patients and to assess the factors that affect survival. BACKGROUND: Much of the standard care of male breast cancer is based on the diagnosis and treatment strategies of female breast cancer. However, important clinical differences between the two have been elucidated, which suggests the need for unique attention to male breast cancer. METHODS: We evaluated the records of male patients who were diagnosed with breast cancer between 2004 and 2015 using the National Cancer Database (NCDB). Data obtained were demographic characteristics, clinical and tumor data, type of therapy, as well as survival data. We used descriptive statistics to characterize our study population. We then performed a survival and Cox proportional hazards analysis. RESULTS: We identified 16,498 patients (median age: 63 years). Several treatment modalities were used, of which surgery was the most common (14,882 [90.4%]). The total follow-up time was 13 years (156 months). Five-year survival was 77.7% (95% CI 76.9-78.4) and 10-year survival was 60.7%. In a Cox proportional hazards model, mastectomy was associated with the greatest survival (hazard ratio [HR] 0.49; p < 0.001). CONCLUSION: We report what is to our knowledge the largest national population-based cohort of male breast cancer patients. Importantly, our data suggests that similar to female patients, several treatment modalities are significantly associated with improved survival in male patients, particularly surgery. Increasing age, black race, government insurance, more comorbidities, and higher tumor stages are associated with decreased survival.

New Persistent Opioid Use After Aortic and Mitral Valve Surgery in Commercially Insured Patients.

BACKGROUND: Deaths from prescription opioid overdose are dramatically increasing. This study evaluates the incidence, risk factors, and cost of new persistent opioid use after aortic valve replacement, mitral valve replacement, and mitral valve repair. METHODS: Insurance claims from commercially insured patients who underwent aortic valve replacement, mitral valve replacement, mitral valve repair, or aortic valve replacement and mitral valve replacement/repair from 2014 to 2016 were evaluated. New persistent opioid use was defined as opioid-naive patients who filled an opioid prescription in the perioperative period and filled opioid prescriptions between 90 and 180 days postoperatively. Multivariable logistic regression identified risk factors for new persistent opioid use. Quantile regression evaluated the impact of new persistent opioid use on total healthcare payments in the 6 months after discharge. RESULTS: Among 3404 opioid-naive patients undergoing aortic valve replacement, mitral valve replacement, or mitral valve repair, 188 (5.5%) had new persistent opioid use. Living in the southern United States (odds ratio, 1.89; 95% confidence interval, 1.35-2.63; P < .001) and increased opioids prescribed in the perioperative period (odds ratio, 1.009; 95% confidence interval, 1.006-1.012; P < .001) were independently associated with new persistent opioid use. After risk adjustment, new persistent opioid use was associated with a 2-fold higher number of emergency department visits (odds ratio, 2.21; 95% confidence interval, 1.61-3.03; P < .001) and a $5422 increase in healthcare payments in the 6 months after discharge. CONCLUSIONS: New persistent opioid use is a significant and costly complication after aortic and mitral valve surgery in privately insured patients. Variation in regional susceptibility and opioid prescribing suggests that standardization may help prevent this complication.

Predictors of new persistent opioid use after coronary artery bypass grafting.

OBJECTIVE: Deaths from prescription opioid overdose have quadrupled in the past 15 years, and no studies have evaluated appropriate opioid prescribing after cardiac surgery. The aim of this study is to quantify the amount of outpatient opioids prescribed to patients after coronary artery bypass grafting and determine the incidence and risk factors for new persistent opioid use after coronary artery bypass grafting. METHODS: Insurance claim data from privately insured opioid-naïve patients who underwent coronary artery bypass grafting from 2014 to 2016 were evaluated. New persistent opioid use was defined as patients who filled an opioid prescription in the perioperative period and filled opioid prescriptions between 90 and 180 days after surgery. Multivariable logistic regression was used to determine the preoperative and operative factors associated with new persistent opioid use. RESULTS: Among 7292 opioid-naïve patients undergoing coronary artery bypass grafting, 5628 (77.2%) filled opioid prescriptions in the perioperative period, and 590 (8.1%) had new persistent opioid use. Female gender (odds ratio [OR], 1.30; confidence interval [CI], 1.05-1.61; P = .018), anxiety (OR, 1.40; CI, 1.09-1.81; P = .009), tobacco use (OR, 1.34; CI, 1.08-1.65; P = .007), prior substance abuse (OR, 1.99; CI, 1.16-3.41; P = .013), chronic obstructive pulmonary disease (OR, 1.29; CI, 1.02-1.63; P = .037), living in the Southern United States (OR, 1.46; CI, 1.21-1.77; P < .001), and increased amount of opioids prescribed in the perioperative period (OR, 1.016; CI, 1.014-1.018; P < .001) were independently associated with new persistent opioid use. CONCLUSIONS: New persistent opioid use after coronary artery bypass grafting is surprisingly common. Prospective studies are needed to determine the opioid requirements of patients after coronary artery bypass grafting to prevent opioid dependence.

Characteristics of Open Globe Injuries in the United States From 2006 to 2014.

Importance: Open globe injuries can lead to substantial visual morbidity and lifelong sequelae. Interventions to reduce the burden of open globe injuries in the United States require a better understanding of these injuries through well-designed epidemiologic investigations. Objective: To examine the incidence, common injury mechanisms, and economic burden of open globe injuries in the United States. Design, Setting, and Participants: This retrospective, cross-sectional study of US nationwide emergency department (ED) data assessed all ED visits of patients with a primary diagnosis of open globe injury in the Nationwide Emergency Department Sample (NEDS) from January 1, 2006, to December 31, 2014. Data analysis was performed from August 29, 2018, to November 11, 2019. Main Outcomes and Measures: Annual incidence of open globe injuries by age, sex, mechanism of injury, and concomitant diagnosis, as well as median charges associated with open globe injuries and variables associated with hospitalization. Results: A total of 124 989 ED visits for open globe injuries were assessed, with an incidence of 4.49 per 100 000 population in the United States from 2006 to 2014 (mean [SD] age of study participants, 37.7 [22.5] years; 94 078 [75.3%] male). The incidence was highest in 2006 (5.88 per 100 000 population) and decreased by 0.3% per month between 2006 and 2014 (incidence rate ratio, 0.99; 95% CI, 0.99-0.99; P < .001). Open globe injuries occurred in 37 060 individuals (30.6%) of low socioeconomic status. The most common injury mechanism was being struck by or against an object or person (40 119 of all 124 989 injury mechanisms [32.1%]). Open globe injuries associated with falls increased 6.6% between 2006-2010 and 2011-2015 (95% CI, 1.04-1.08; P < .001) and were the most common injury mechanism in individuals older than 70 years. The total cost associated with open globe injuries was $793 million. The cost of ED visits increased from $865 during 2006-2010 to $1557 during 2011-2015. Inpatient costs similarly increased from $21 527 during 2006-2010 to $30 243 during 2011-2015. Conclusions and Relevance: The incidence of open globe injuries in the United States decreased from 2006 to 2014. Although the data are from 5 to 13 years ago, these findings appear to provide valuable information for targeting preventive measures toward individuals at highest risk; targeting young men with lower socioeconomic status and individuals 70 years or older at an increased risk of falls may help lower the incidence of open globe injuries.
