Trends in interstate abortion travel to Oregon following the Dobbs court decision.

OBJECTIVES: This study describes how interstate travel for abortion to the state of Oregon changed following the Dobbs decision. STUDY DESIGN: We conducted a retrospective cohort study using vital statistics data from the Oregon Health Authority of all medical and surgical abortions between 2015 and 2023. RESULTS: Following the Dobbs decision, 14.3% of abortions in Oregon were out-of-state residents, compared to 9.6% pre-Dobbs. Out-of-state individuals had significantly higher odds of having abortions in the second or third trimester and having a procedural abortion compared to their in-state counterparts. CONCLUSIONS: Following the Dobbs decision, interstate travel to Oregon increased significantly and represents a distinct population.

Risk of Adverse Neonatal Outcomes After Combined Prenatal Cannabis and Nicotine Exposure.

Importance: The prevalence of cannabis use in pregnancy is rising and is associated with adverse perinatal outcomes. In parallel, combined prenatal use of cannabis and nicotine is also increasing, but little is known about the combined impact of both substances on pregnancy and offspring outcomes compared with each substance alone. Objective: To assess the perinatal outcomes associated with combined cannabis and nicotine exposure compared with each substance alone during pregnancy. Design, Setting, and Participants: This retrospective population-based cohort study included linked hospital discharge data (obtained from the California Department of Health Care Access and Information) and vital statistics (obtained from the California Department of Public Health) from January 1, 2012, through December 31, 2019. Pregnant individuals with singleton gestations and gestational ages of 23 to 42 weeks were included. Data were analyzed from October 14, 2023, to March 4, 2024. Exposures: Cannabis-related diagnosis and prenatal nicotine product use were captured using codes from International Classification of Diseases, Ninth Revision, Clinical Modification, and International Statistical Classification of Diseases, Tenth Revision, Clinical Modification. Main Outcome and Measures: The main outcomes were infant and neonatal death, infants small for gestational age, and preterm delivery. Results were analyzed by multivariable Poisson regression models. Results: A total of 3 129 259 pregnant individuals were included (mean [SD] maternal age 29.3 [6.0] years), of whom 23 007 (0.7%) had a cannabis-related diagnosis, 56 811 (1.8%) had a nicotine-use diagnosis, and 10 312 (0.3%) had both in pregnancy. Compared with nonusers, those with cannabis or nicotine use diagnoses alone had increased rates of infant (0.7% for both) and neonatal (0.3% for both) death, small for gestational age (14.3% and 13.7%, respectively), and preterm delivery (<37 weeks) (12.2% and 12.0%, respectively). Moreover, risks in those with both cannabis and nicotine use were higher for infant death (1.2%; adjusted risk ratio [ARR], 2.18 [95% CI, 1.82-2.62]), neonatal death (0.6%; ARR, 1.76 [95% CI, 1.36-2.28]), small for gestational age (18.0%; ARR, 1.94 [95% CI, 1.86-2.02]), and preterm delivery (17.5%; ARR, 1.83 [95% CI, 1.75-1.91]). Conclusions and Relevance: These findings suggest that co-occurring maternal use of cannabis and nicotine products in pregnancy is associated with an increased risk of infant and neonatal death and maternal and neonatal morbidity compared with use of either substance alone. Given the increasing prevalence of combined cannabis and nicotine use in pregnancy, these findings can help guide health care practitioners with preconception and prenatal counseling, especially regarding the benefits of cessation.

Impact of the Dobbs decision on abortion services from a large tertiary center in Oregon.

OBJECTIVES: Evaluate the impact of the Dobbs vs Jackson decision on abortion care at an academic center in Oregon, a state with no legal restrictions on abortion. STUDY DESIGN: Electronic health records from patients who received an abortion at Oregon's largest tertiary hospital were utilized to compare the years before and after Dobbs. RESULTS: Monthly average abortions increased from 57.8 pre-Dobbs to 77.1 post-Dobbs (p = 0.001). This trend was associated with an increased proportion of out-of-state patients (14.3% vs 9.5%, p = 0.004) presenting with gestational duration ≥26 weeks (23.6% vs 3.7% in-state, p < 0.001). CONCLUSIONS: The Dobbs decision resulted in increased utilization of hospital-based abortion care in a protective state. IMPLICATIONS: This study reflects the critical role of protective states such as Oregon in preserving access to abortion services and the need for continued support to alleviate the impact of nationwide barriers to reproductive healthcare.

Cannabis and Pregnancy: A Review.

Importance: Prenatal cannabis use is rising and is a major public health issue. Cannabis use in pregnancy and during lactation has been associated with increased maternal and offspring morbidity and mortality. Objective: This review aims to summarize the existing literature and current recommendations for cannabis use during pregnancy or lactation. Evidence Acquisition: A PubMed, Cochrane Library, and Google Scholar literature search using the following terms was performed to gather relevant data: "cannabis," "cannabinoid," "delta-9-tetrahydrocannabinol," "THC," "cannabidiol," "fetal outcomes," "perinatal outcomes," "pregnancy," and "lactation." Results: Available studies on cannabis use in pregnancy and during lactation were reviewed and support an association with increased risk of preterm birth, neonatal intensive care unit admission, low birth weight, and small-for-gestational-age infants. Conclusion and Relevance: There is a critical need for research on the effects of cannabis use in pregnancy and during lactation. This is a necessary first step before furthering patient education, developing interventions, and targeting antenatal surveillance to ameliorate the adverse impacts on maternal and fetal health.

Adverse Perinatal and Neonatal Outcomes among Adolescent Pregnancies in the United States.

OBJECTIVE: Despite a downward trend in recent years, adolescent pregnancies in the United States remain higher than any other western country. Adolescent pregnancies have been inconsistently associated with adverse perinatal outcomes. The objective of this study is to investigate the association between adolescent pregnancies and adverse perinatal and neonatal outcomes in the United States. STUDY DESIGN: This is a retrospective cohort study of singleton births in the United States from 2014 to 2020 using national vital statistics data. Perinatal outcomes included gestational diabetes, gestational hypertension, preterm delivery <37 weeks (preterm birth [PTB]), cesarean delivery (CD), chorioamnionitis, small for gestational age (SGA), large for gestational age (LGA), and neonatal composite outcome. Chi-square tests were used to compare outcomes among adolescent (13-19 years) versus adult (20-29 years) pregnancies. Multivariable logistic regression models were used to examine association of adolescent pregnancies with perinatal outcomes. For each outcome, we utilized three models: unadjusted logistic regression, adjusted for demographics, and adjusted for demographics and medical comorbidities. Similar analyses were used to compare younger (13-17 years) and older (18-19 years) adolescent pregnancies to adults. RESULTS: In a cohort of 14,014,078 pregnancies, we found that adolescents were at an increased risk of PTB (adjusted odds ratio [aOR]: 1.12, 99% confidence interval (CI): 1.12-1.13) and SGA (aOR: 1.02, 99% CI: 1.01-1.03) compared with adult pregnancies. We also found that multiparous adolescents with a prior history of CD were at an increased risk of CD, compared with adults. For all other outcomes, adult pregnancies were at higher risk for adverse outcomes in the adjusted models. When comparing birth outcomes among adolescents, we found that older adolescents are at an increased risk of PTB, whereas younger adolescents are at an increased risk of both PTB and SGA. CONCLUSION: After adjusting for confounders, our study demonstrates adolescents have an increased risk of PTB and SGA, compared with adults. KEY POINTS: · Adolescents as a whole subgroup have an increased risk of PTB and SGA compared with adults.. · Younger adolescents have a risk of PTB and SGA, whereas older adolescents have a risk of PTB only.. · Adverse birth outcomes in adults are gestational diabetes, chorioamnionitis, LGA, and worse neonatal composite score..

Preventing eviction during pregnancy: a cost-effectiveness analysis of a theoretical safety-net program.

BACKGROUND: Eviction during pregnancy has been shown to be associated with adverse birth outcomes. A safety net program focused on covering the costs of rent during pregnancy may aid in preventing adverse complications. OBJECTIVE: This study aimed to evaluate the cost-effectiveness of a program covering the cost of rent to prevent eviction during pregnancy. STUDY DESIGN: A cost-effectiveness model using TreeAge software was designed to evaluate the cost, effectiveness, and incremental cost-effectiveness ratio associated with eviction compared to no eviction during pregnancy. The cost of eviction from a societal perspective was compared to the annual cost of housing in the no eviction group, which was estimated by the median contract rent in the United States from 2021 national census data. Birth outcomes included preterm birth, neonatal death, and major neurodevelopmental delay. Probabilities and costs were derived from the literature. The cost-effectiveness threshold was set at $100,000/QALY. We performed univariable and multivariable sensitivity analyses to assess the robustness of the results. RESULTS: In our theoretical cohort of 30,000 pregnant individuals aged 15 to 44 years facing eviction annually, the no eviction during pregnancy strategy was associated with 1427 fewer preterm births, 47 fewer neonatal deaths, and 44 fewer cases of neurodevelopmental delay compared to eviction. At the median cost of rent in the United States, the no eviction strategy was associated with increased quality-adjusted life-years and decreased costs. Therefore, the no eviction strategy was the dominant strategy. In univariate sensitivity analysis varying the cost of housing, no eviction remained the cost-effective strategy and was cost-saving when rent was below $1016 per month. CONCLUSION: The no eviction strategy is cost-effective and reduces cases of preterm birth, neonatal death, and neurodevelopmental delay. When rent is below the median of $1016 per month, no eviction is the cost-saving strategy. These findings suggest that policies supporting social programmatic implementation for rent coverage for pregnant people at risk of eviction have the potential to be highly beneficial in reducing costs and disparities in perinatal outcomes.

Association Between Rates of Down Syndrome Diagnosis in States With vs Without 20-Week Abortion Bans From 2011 to 2018.

Importance: Many states enacted 20-week abortion bans from 2011 to 2018. Such bans affect individuals who receive diagnoses of fetal anomalies and aneuploidy in the second trimester, preventing pregnant individuals from having the choice of whether or not to continue the pregnancy. Objectives: To examine the trends of neonatal Down syndrome rates and assess the association between enactment of 20-week abortion bans and rates of Down syndrome diagnosis. Design, Setting, and Participants: This population-based, historical cohort study used National Vital Statistics System data on 31 157 506 births in the US from 2011 to 2018. Statistical analysis was performed from May 2021 to February 2023. Exposure: States were categorized as those with or without a 20-week abortion ban enacted during the study period. Main Outcomes and Measures: Demographic characteristics between the ban and no-ban states were compared using χ2 tests and 2-sample t tests. Multivariable logistic regression evaluated the adjusted odds of Down syndrome among births in states that enacted 20-week abortion bans after the abortion ban enactment, adjusting for state, year of birth, maternal race and ethnicity, age, educational level, insurance, and number of prenatal visits. Results: The cohort consisted of 31 157 506 births (mean [SD] maternal age, 28.4 [5.9] years) in the United States, of whom 15 951 neonates (0.05%) received a diagnosis of Down syndrome at birth. A total of 17 states enacted 20-week abortion bans during the study period, and 33 states did not enact bans. In both states with and states without bans, the birth prevalence of neonatal Down syndrome increased over time; in states with bans, rates increased from 48.0 to 58.4 per 100 000 births; in states without bans, rates increased from 47.4 to 53.3 per 100 000 births. In multivariable logistic regression assessing the interaction of time and presence of a 20-week abortion ban, the odds of Down syndrome were higher in states that enacted 20-week abortion bans after enactment of the law compared with the years prior to enactment of the ban (adjusted odds ratio, 1.22; 95% CI, 1.11-1.35). Conclusions and Relevance: In the US from 2011 to 2018, neonatal Down syndrome diagnoses increased more in states that enacted 20-week abortion bans compared with states that did not enact bans. Because these abortion bans were enacted throughout the study period and are known to inhibit choice in patient decision-making, it is possible that the difference in the rates of diagnosis is associated with these policies.

Frailty is independently associated with worse outcomes and increased resource utilization following endometrial cancer surgery.

OBJECTIVE: Frailty has been associated with poorer surgical outcomes and is a critical factor in procedural risk assessment. The objective of this study is to assess the impact of frailty on surgical outcomes in patients with endometrial cancer. METHODS: Patients undergoing inpatient gynecologic surgery for endometrial cancer were identified using the 2005-2017 Nationwide Inpatient Sample database. The Johns Hopkins Adjusted Clinical Groups frailty-defining diagnosis indicator was used to designate frailty. Multivariate regression models were used to assess the association of frailty with postoperative outcomes and resource use. RESULTS: Of 339 846 patients, 2.9% (9868) were considered frail. After adjusting for patient and hospital characteristics, frailty was associated with a four-fold increase in inpatient mortality (adjusted OR (aOR) 4.1; p<0.001), non-home discharge (aOR 5.2; p<0.001), as well as increased respiratory (aOR 2.6; p<0.001), neurologic (aOR 3.3; p<0.001), renal (aOR 2.0; p<0.001), and infectious (aOR 3.2; p<0.001) complications. While frail patients exhibited increased mortality with age, the rate of mortality in this cohort decreased significantly over time. Compared with non-frail counterparts, frail patients had longer lengths of stay (7.6 vs 3.4 days; p<0.001) and increased hospitalization costs with surgical admission ($25 093 vs $13 405; p<0.001). CONCLUSIONS: Frailty is independently associated with worse surgical outcomes, including increased mortality and resource use, in women undergoing surgery for endometrial cancer. Though in recent years there have been improvements in mortality in the frail population, further efforts to mitigate the impact of frailty should be explored.

Impact of Frailty on Clinical Outcomes and Hospitalization Costs Following Elective Colectomy.

BACKGROUND: Frailty has been increasingly recognized as a risk factor for inferior surgical outcomes and greater resource use. The present study evaluated the impact of a coding-based frailty tool on outcomes of elective colectomy in a national cohort. STUDY DESIGN: Adults undergoing elective colectomy were identified in the 2016-17 Nationwide Readmissions Database. Frailty was defined using the Johns Hopkins 10-domain coding-based binary tool. Generalized linear models were used to examine the association of frailty with in-hospital mortality, nonhome discharge, hospitalization duration (LOS), and inflation-adjusted costs. Kaplan-Meier survival analysis and log-rank test was used to compare readmissions up to 1-year. RESULTS: Of 133 175 patients, 10.6% were considered frail. The most common resections were sigmoid (43.9%) and right (34.7%) while total colectomy was least common (2.8%). After adjustment, frailty was associated with greater odds of mortality (3.2, 95% CI 2.8-3.8) and nonhome discharge (6.0, 95% CI 5.5-6.4) as well as a $13,400-increment (95% CI 12,400-14,400) in costs and 4.4-day (95% CI 4.1-4.6) increase in LOS. Nonelective readmissions at 30 days were greater in frail than non-frail groups (14.7% vs. 10.4%, P < .001). CONCLUSION: Frailty is associated with inferior clinical outcomes and increased resource use following elective colectomy. Inclusion of frailty in risk models may facilitate risk stratification and shared decision-making.

National Trends in the Cost Burden of Pediatric Gunshot Wounds Across the United States.

OBJECTIVE: To characterize hospitalization costs attributable to gun-related injuries in children across the US. STUDY DESIGN: The 2005-2017 National Inpatient Sample was used to identify all pediatric admissions for gunshot wounds (GSW). Patients were stratified by International Classification of Diseases procedural codes for trauma-related operations. Annual trends in GSW hospitalizations and costs were analyzed with survey-weighted estimates. Multivariable regressions were used to identify factors associated with high-cost hospitalizations. RESULTS: During the study period, an estimated 36 283 pediatric patients were admitted for a GSW, with 43.1% undergoing an operative intervention during hospitalization. Admissions for pediatric firearm injuries decreased from 3246 in 2005 to 3185 in 2017 (NPtrend < .001). The median inflation-adjusted cost was $12 408 (IQR $6253-$24 585). Median costs rose significantly from $10 749 in 2005 to $16 157 in 2017 (P < .001). Compared with those who did not undergo surgical interventions, operative patients incurred increased median costs ($18 576 vs $8942, P < .001). Assault and self-harm injuries as well as several operations were independently associated with classification in the highest cost tertile. CONCLUSIONS: Admissions for pediatric firearm injuries were associated with a significant socioeconomic burden in the US, with increasing resource use over time. Pediatric gun violence is a major public health crisis that warrants further research and advocacy to reduce its prevalence and social impact.

Impact of hospital safety-net status on clinical outcomes following carotid artery revascularization.

BACKGROUND: High hospital safety-net burden has been associated with inferior clinical outcomes. We aimed to characterize the association of safety-net burden with outcomes in a national cohort of patients undergoing carotid interventions. METHODS: The 2010-2017 Nationwide Readmissions Database was used to identify adults undergoing carotid endarterectomy and carotid artery stenting. Hospitals were classified as low (LBH), medium, or high safety-net burden (HBH) based on the proportion of uninsured or Medicaid patients. Multivariable models were developed to evaluate associations between HBH and outcomes. RESULTS: Of an estimated 540,558 hospitalizations for a carotid intervention, 28.5% were at HBH. Patients treated at HBH were more likely to be admitted non-electively (28.7% vs 20.2%, P < .001), have symptomatic presentation (11.0% vs 7.7%, P < .001), and undergo carotid artery stenting (18.7% vs 8.9%, P < .001). After adjustment, HBH remained associated with increased odds of postoperative stroke (AOR 1.19, P = .023, Ref = LBH), non-home discharge (AOR 1.10, P = .026), 30-day readmissions (AOR 1.14, P < .001), and 31-90-day readmissions (AOR 1.13, P < .001), but not in-hospital mortality (AOR 1.18, P = .27). HBH was linked to increased hospitalization costs (ß +$2,169, P = .016). CONCLUSION: HBH was associated with postoperative stroke, non-home discharge, readmissions, and increased hospitalization costs after carotid revascularization. Further studies are warranted to alleviate healthcare inequality and improve outcomes at safety-net hospitals.

National trends and predictors of mastectomy with immediate breast reconstruction.

PURPOSE: This study aimed to evaluate national trends in utilization, resource use, and predictors of immediate breast reconstruction (IR) after mastectomy. METHODS: The 2005-2014 National Inpatient Sample database was used to identify adult women undergoing mastectomy. IR was defined as any reconstruction during the same inpatient stay. Multivariable regression models were utilized to identify factors associated with IR. RESULTS: Of 729,340 patients undergoing mastectomy, 41.3% received IR. Rates of IR increased from 28.2% in 2005 to 58.2% in 2014 (NP-trend<0.001). Compared to mastectomy alone, IR was associated with increased length of stay (2.5 vs. 2.1 days, P < 0.001) and hospitalization costs ($17,628 vs. $8,643, P < 0.001), which increased over time (P < 0.001). Predictors of IR included younger age, fewer comorbidities, White race, private insurance, top income quartile, teaching hospital designation, high mastectomy volume, and performance of bilateral mastectomy. CONCLUSION: Mastectomy with IR is increasingly performed with resource utilization rising at a steady pace. Our study points to persistent sociodemographic and hospital level disparities associated with the under-utilization of IR. Efforts are needed to alleviate disparities in IR.

Outcomes and resource use for liver transplantation in the United States: Insights from the 2009-2017 National Inpatient Sample.

INTRODUCTION: Liver transplantation (LT) is a life-saving treatment for end-stage liver disease patients that requires significant resources. We used national data to evaluate LT outcomes and factors associated with hospital resource use. METHODS: Using the National Inpatient Sample, we identified all patients undergoing LT from 2009 to 2017 and defined high-resource use (HRU) as having costs ≥ 90th percentile. Hierarchical regression models were used to assess factors associated with length of stay (LOS) and HRU. RESULTS: Over the study period, approximately 53,000 patients underwent LT, increasing from 5,582 in 2009 to 7,095 in 2017 (nptrend < 0.001). Morbidity and mortality were 42.2% and 3.9%, respectively, with a median post-LT LOS of 10 days. Hospitalization costs increased from $106,866 to $145,868 (nptrend < 0.001). Acute kidney injury (ß:4.7 days, P < .001) and end-stage renal disease (ESRD) with dialysis (ß:4.3 days, P < .001) were associated with greater LOS while the Northeast region (AOR:5.2, P < .001), ESRD with dialysis (AOR:3.4, P < .001), heart failure (AOR:2.5, P < .001), and fulminant liver disease (AOR:1.8, P = .01) were associated with HRU. CONCLUSION: The cost of LT has increased over time. Renal dysfunction, regional practice patterns, and patient acuity were associated with greater resource use. Transplanting patients before health deterioration may help contain costs, mitigate resource use, and improve LT outcomes.

Outcomes and Resource Use Associated With Acute Respiratory Failure in Safety Net Hospitals Across the United States.

BACKGROUND: Despite the frequency and cost of hospitalizations for acute respiratory failure (ARF), the literature regarding the impact of hospital safety net burden on outcomes of these hospitalizations is sparse. RESEARCH QUESTION: How does safety net burden impact outcomes of ARF hospitalizations such as mortality, tracheostomy, and resource use? STUDY DESIGN AND METHODS: This was a retrospective cohort study using the National Inpatient Sample 2007-2017. All patients hospitalized with a primary diagnosis of ARF were tabulated using the International Classification of Diseases 9th and 10th Revision codes, and safety net burden was calculated using previously published methodology. High- and low-burden hospitals were generated from proportions of Medicaid and uninsured patients. Trends were analyzed using a nonparametric rank-based test, whereas multivariate logistic and linear regression models were used to establish associations of safety net burden with key clinical outcomes. RESULTS: Of an estimated 8,941,334 hospitalizations with a primary diagnosis of ARF, 33.9% were categorized as occurring at low-burden hospitals (LBHs) and 31.6% were categorized as occurring at high-burden hospitals (HBHs). In-hospital mortality significantly decreased at HBHs (22.8%-12.6%; nonparametric trend [nptrend] < .001) and LBHs (22.0%-10.9%; nptrend < .001) over the study period, as did tracheostomy placement (HBH, 5.6%-1.3%; LBH, 3.5%-0.8%; all nptrend <.001). After adjustment for patient and hospital factors, an HBH was associated with increased odds of mortality (adjusted OR [AOR], 1.11; 95% CI, 1.10-1.12) and tracheostomy use (AOR, 1.33; 95% CI, 1.29-1.37), as well as greater hospitalization costs (ß coefficient, +$1,083; 95% CI, $882-$1,294) and longer lengths of stay (ß coefficient, +3.3 days; 95% CI, 3.2-3.3 days). INTERPRETATION: After accounting for differences between patient cohorts, high safety net burden was associated independently with inferior clinical outcomes and increased costs after ARF hospitalizations. These findings emphasize the need for health care reform to ameliorate disparities within these safety net centers, which treat our most vulnerable populations.

Impact of Frailty on Clinical Outcomes after Carotid Artery Revascularization.

BACKGROUND: Frailty has been increasingly recognized as an important risk factor for vascular procedures. To assess the impact of frailty on clinical outcomes and resource utilization in patients undergoing carotid revascularization using a national cohort. METHODS: The 2005-2017 National Inpatient Sample was used to identify patients who underwent carotid endarterectomy (CEA) or carotid stenting (CAS). Patients were classified as frail using diagnosis codes defined by the Johns Hopkins Adjusted Clinical Groups frailty indicator. Multivariable regression was used to evaluate associations between frailty and in-hospital mortality, postoperative stroke, myocardial infarction (MI), hospitalization costs, and length of stay (LOS). RESULTS: Of 1,426,343 patients undergoing carotid revascularization, 59,158 (4.2%) were identified as frail. Among frail patients, 79.4% underwent CEA and 20.6% underwent CAS. Compared to CEA, a greater proportion of patients undergoing CAS were frail (6.0% vs. 3.8%, P < 0.001). Compared to the nonfrail cohort, frail patients had higher rates of mortality (2.2% vs. 0.5%, P < 0.001), postoperative stroke (2.6% vs. 1.0%, P < 0.001), MI (2.2% vs. 0.8%, P < 0.001), and stroke/death (4.4% vs. 1.4%, P < 0.001). After adjustment, frailty was associated with increased odds of mortality (AOR = 1.59, 95% CI: 1.30-1.80, P < 0.001), stroke (AOR = 1.66, 95% CI: 1.38-1.83 P < 0.001), MI (AOR = 1.51, 95% CI: 1.29-1.72, P < 0.001), and stroke/death (AOR = 1.62, 95% CI: 1.45-1.81, P < 0.001). Furthermore, frailty was associated with increased hospitalization costs (ß = +$5,980, 95% CI: $5,490-$6,470, P < 0.001) and LOS (ß = +2.6 days, 95% CI: 2.4-2.8, P < 0.001). CONCLUSIONS: Frailty is associated with adverse outcomes and greater resource use for those undergoing carotid revascularization. Risk models should include an assessment of frailty to guide management and improve outcomes for these high-risk patients.

Frailty Is Independently Associated With Worse Outcomes After Elective Anatomic Lung Resection.

BACKGROUND: Frailty has been widely recognized as a predictor of postoperative outcomes. Given the paucity of standardized frailty measurements in thoracic procedures, this study aimed to determine the impact of coding-based frailty on clinical outcomes and resource use after anatomic lung resection. METHODS: All adults undergoing elective, anatomic lung resections (segmentectomy, lobectomy, pneumonectomy) from 2005 to 2014 were identified using the National Inpatient Sample. Patients were categorized as either frail or nonfrail on the basis of the presence of any frailty-defining diagnoses defined by the Johns Hopkins Adjusted Clinical Groups. Multivariable models were used to assess the independent association of frailty with in-hospital mortality, nonhome discharge, complications, duration of stay, and costs. RESULTS: Of an estimated 366,357 hospitalizations for elective lung resection during the study period, 4.4% were in frail patients. Patients who underwent pneumonectomy or were treated at low-volume hospitals were more commonly frail. Relative to nonfrail patients, frailty was associated with increased unadjusted mortality (9.1% vs 1.7%; P < .001) and nonhome discharge (44.7% vs 10.5%; P < .001). Frail patients had 3.47 increased adjusted odds of mortality across resection types (95% confidence interval, 2.94 to 4.09). Frailty conferred the greatest increase in mortality, complications, and resource use after pneumonectomy relative to lobectomy or segmentectomy, although significant differences were evident for all 3 operations. CONCLUSIONS: Frailty exhibits a strong association with inferior clinical outcomes and increased resource use after elective lung resection, particularly pneumonectomy. This readily available tool may improve preoperative risk assessment and allow for better selection of treatment modalities for frail patients with pulmonary disorders.

Factors associated with high-cost hospitalizations in elderly ovarian cancer patients.

OBJECTIVE: To characterize factors associated with high-cost inpatient admissions for ovarian cancer. METHODS: Operative hospitalizations for ovarian cancer patients ≥65 years of age were identified using the 2010-2017 National Inpatient Sample. Admissions with high-cost were defined as those incurring ≥90th percentile of hospitalization costs each year, while the remainder were considered low-cost. Multivariable logistic regression models were developed to assess independent predictors of being in the high-cost cohort. RESULTS: During the study period, an estimated 58,454 patients met inclusion criteria. 5827 patient admissions (9.98%) were classified as high-cost. Median hospitalization cost for this high-cost group was $55,447 (interquartile range (IQR) $46,744-$74,015) compared to $16,464 (IQR $11,845-$23,286, p < 0.001) for the low-cost group. Patients with high-cost admissions were more likely to have received open (adjusted odds ratio (AOR) 2.23, 1.31-3.79) or extended (AOR 5.64, 4.79-6.66) procedures and be admitted non-electively (AOR 3.32, 2.74-4.02). Being in the top income quartile (AOR 1.77, 1.39-2.27) was also associated with high-cost. Age and hospital factors, including bed size and volume of gynecologic oncology surgery, did not affect cost group. CONCLUSION: High-cost ovarian cancer admissions were three times more expensive than low-cost admissions. Fewer open and extended procedures with subsequently shorter lengths of stay may have contributed to decreasing inpatient costs over the study period. In this cohort of patients largely covered by Medicare, clinical factors outweigh socioeconomic factors as cost drivers. Understanding the relationship of disease-specific and social factors to cost will be important in informing future value-based quality improvement efforts in gynecologic cancer care.

National Trends in Immediate Breast Reconstruction: An Analysis of Implant-Based Versus Autologous Reconstruction After Mastectomy.

BACKGROUND: Many factors affect access to immediate breast reconstruction (IR) after mastectomy. The present study was performed to assess trends, outcomes, and predictors of IR techniques using a nationally representative cohort. METHODS: The 2009-2014 National Inpatient Sample (NIS) was used to identify adult women who underwent inpatient mastectomy with IR. Patients were compared by type of reconstruction: implant-based IR versus autologous reconstruction (AR). AR was classified as a microsurgical or pedicled flap procedure. Incidence, outcomes, and predictors were assessed using Chi squared univariate tests and multivariable logistic regression analyses. RESULTS: Of 194,073 women who underwent IR, 136,668 (70.4%) received implant-based IR and 57,405 (29.6%) received AR. Of those who underwent AR procedures, 31,336 (54.6%) received microsurgical flaps and 26,680 (46.5%) received pedicled flaps. Utilization of deep inferior epigastric perforator (DIEP) flaps increased significantly (28.6-42.5% of AR, P < 0.001). Predictors of AR were Black race [adjusted odds ratio (AOR) = 1.46, P < 0.001], lower Elixhauser Comorbidity Index (AOR = 1.25, P < 0.001), private insurance (AOR = 1.07, P = 0.030), body mass index (BMI) ≥ 30 kg/m2 (AOR = 1.38, P < 0.001), urban teaching hospital designation (AOR = 1.77, P < 0.001), and high hospital volume (AOR = 3.11, P < 0.001). Similar factors were associated with the use of microsurgical flaps. AR and microsurgical flaps were associated with higher rates of acute inpatient complications, resource utilization and length of stay (LOS) compared with implant-based IR and pedicled flaps, respectively. CONCLUSION: Implant-based IR remains the most common type of IR, although rates of microsurgical AR are on the rise. Follow-up of complications, costs, and quality-of-life measures may show that AR provides long-term high-value care despite upfront morbidity, cost, and use of hospital resources.

Impact of Hospital Volume on Outcomes of Elective Pneumonectomy in the United States.

BACKGROUND: Despite advances in surgical technique and perioperative management, pneumonectomy remains associated with significant morbidity and mortality. The purpose of this study was to examine the impact of annual institutional volume of anatomic lung resections on outcomes after elective pneumonectomy. METHODS: We evaluated all patients who underwent elective pneumonectomy from 2005 to 2014 in the National Inpatient Sample. Patients less than 18 years of age, or with trauma-related diagnoses, mesothelioma, or a nonelective admission were excluded. Hospitals were divided into volume quartiles based on annual institutional anatomic lung resection caseload. We studied the effect of institutional volume on inhospital mortality, complications, and failure to rescue, as well as costs and length of stay. RESULTS: During the study period, an estimated 22,739 patients underwent pneumonectomy, with a reduction in national mortality from 7.9% to 5.5% (P trend = .045). Compared with the highest volume centers, operations performed at the lowest volume hospitals were associated with 1.74 increased odds of mortality (95% confidence interval, 1.14 to 2.66). Despite similar odds of postoperative complications, low volume hospital status was associated with increased failure to rescue rates (18.3% vs 12.7%, P = .024) and adjusted odds of mortality (1.70; 95% confidence interval, 1.09 to 2.64) after any complication. CONCLUSIONS: High volume hospital status is strongly associated with reduced mortality and failure to rescue rates after pneumonectomy. Efforts to centralize care or disseminate best practices may lead to improved national outcomes for this high-risk procedure.
