Abstract
OBJECTIVE Our objective was to gauge adherence to nationally endorsed protocols in implementation of pulse oximetry (POx) screening for critical congenital heart disease (CCHD) in infants after mandate by all states and to assess associated characteristics. STUDY DESIGN Between March and October 2019, an online questionnaire was administered to nurse supervisors who oversee personnel conducting POx screening. The questionnaire used eight questions regarding performance and interpretation of screening protocols to measure policy consistency, which is adherence to nationally endorsed protocols for POx screening developed by professional medical societies. Multilevel linear regression models evaluated associations between policy consistency and characteristics of hospitals and individuals, state of hospital location, early versus late mandate adopters, and state reporting requirements. RESULTS Responses from 189 nurse supervisors spanning 38 states were analyzed. Only 17% received maximum points indicating full policy consistency, and 24% selected all four options for potential hypoxia that require a repeat screen. Notably, 33% did not recognize ≤90% SpO2 as an immediate failed screen and 31% responded that an infant with SpO2 of 89% in one extremity will be rescreened by nurses in an hour rather than receiving an immediate physician referral. Lower policy consistency was associated with lack of state reporting mandates (beta = -1.23 p = 0.01) and early adoption by states (beta = -1.01, p < 0.01). CONCLUSION When presented with SpO2 screening values on a questionnaire, a low percentage of nurse supervisors selected responses that demonstrated adherence to nationally endorsed protocols for CCHD screening. Most notably, almost one-third of respondents did not recognize ≤90% SpO2 as a failed screen that requires immediate physician follow-up. In addition, states without reporting mandates and early adopter states were associated with low policy consistency. Implementing state reporting requirements might increase policy consistency, but some inconsistency may be the result of unique protocols in early adopter states that differ from nationally endorsed protocols. KEY POINTS · Low adherence to nationally endorsed protocols.. · Inconsistent physician follow-up to hypoxia.. · Reporting improved consistency with national policy..

Abstract
Importance Short interpregnancy intervals (SIPIs) are associated with increased risk of adverse maternal and neonatal outcomes. Disparities exist across socioeconomic status, but there is little information on SIPIs among women experiencing homelessness. Objective To investigate (1) differences in rates and characteristics of SIPIs between women experiencing homelessness and domiciled women, (2) whether the association of homelessness with SIPIs differs across races and ethnicities, and (3) whether the association between SIPIs of less than 6 months (very short interpregnancy interval [VSIPIs]) and maternal and neonatal outcomes differs between participant groups. Design, Setting, and Participants This cohort study used a Colorado statewide database linking the Colorado All Payer Claims Database, Homeless Management Information System, death records, and infant birth records. Participants included all women who gave birth between January 1, 2016, and December 31, 2021. Data were analyzed from September 1, 2022, to May 10, 2023. Exposures Homelessness and race and ethnicity. Main Outcomes and Measures The primary outcome consisted of SIPI, a binary variable indicating whether the interval between delivery and conception of the subsequent pregnancy was shorter than 18 months. The association of VSIPI with maternal and neonatal outcomes was also tested. Results A total of 77 494 women (mean [SD] age, 30.7 [5.3] years) were included in the analyses, of whom 636 (0.8%) were women experiencing homelessness. The mean (SD) age was 29.5 (5.4) years for women experiencing homelessness and 30.7 (5.3) years for domiciled women. In terms of race and ethnicity, 39.3% were Hispanic, 7.3% were non-Hispanic Black, and 48.4% were non-Hispanic White. Associations between homelessness and higher odds of SIPI (adjusted odds ratio [AOR], 1.23 [95% CI, 1.04-1.46]) were found. Smaller associations between homelessness and SIPI were found among non-Hispanic Black (AOR, 0.59 [95% CI, 0.37-0.96]) and non-Hispanic White (AOR, 0.57 [95% CI, 0.39-0.84]) women compared with Hispanic women. A greater association of VSIPI with emergency department visits and low birth weight was found among women experiencing homelessness compared with domiciled women, although no significant differences were detected. Conclusions and Relevance In this cohort study of women who gave birth from 2016 to 2021, an association between homelessness and higher odds of SIPIs was found. These findings highlight the importance of conception management among women experiencing homelessness. Racial and ethnic disparities should be considered when designing interventions.

Abstract
BACKGROUND A decrease in the incidence of Kawasaki disease during the COVID-19 pandemic has been reported globally. Yet, previous US studies utilized patient populations of limited size and geographic scope, leaving a knowledge gap regarding the national trend. Employing a large sample size will increase the generalizability of the results and allow for more detailed analyses. METHODS The observational study using the 2016-2020 National (Nationwide) Inpatient Sample examined changes in the Kawasaki disease hospitalization rate in pediatric patients during the COVID-19 pandemic. Sensitivity analyses examined hospitalizations between October and December each year, as the code for multisystem inflammatory syndrome in children was implemented in October 2020. RESULTS In total, 24,505 hospitalizations with Kawasaki disease diagnoses were examined. Hospitalization rates were 65.1 and 53.8 per 1,000,000 pediatric population during the prepandemic and pandemic periods, respectively. Sensitivity analyses showed an overall decrease of 36.1%, with larger decreases for patients 1-4 years old (49.6%), males (40.0%), Asians or Pacific Islanders (57.9%) and patients in the South (47.5%), compared with their counterparts. Associations of the pandemic period with longer lengths of stay and higher daily costs were detected (adjusted mean ratio 1.11; P < 0.01 for length of stay, and adjusted mean ratio 1.33, P < 0.01 for costs). CONCLUSIONS A decrease in the incidence of Kawasaki disease during the COVID-19 pandemic was observed nationwide in the United States. Contrary to a report from Japan, we did not observe a relationship between population density and a decrease in Kawasaki disease hospitalization. More detailed analyses in targeted geographical areas may provide further insights.

Abstract
We evaluated the association between implementation of state-mandated pulse oximetry screening (POS) and rates of emergency hospitalizations among infants with Critical Congenital Heart Disease (CCHD) and assessed differences in that association across race/ethnicity. We hypothesized that emergency hospitalizations among infants with CCHD decreased after implementation of mandated POS and that the reduction was larger among racial and ethnic minorities compared to non-Hispanic Whites. We utilized statewide inpatient databases from Arizona, California, Kentucky, New Jersey, New York, and Washington State (2010-2014). A difference-in-differences model with negative binomial regression was used. We identified patients with CCHD whose hospitalizations between three days and three months of life were coded as "emergency" or "urgent" or occurred through the emergency department. Numbers of emergency hospitalizations aggregated by month and state were used as outcomes. The intervention variable was an implementation of state-mandated POS. Difference in association across race/ethnicity was evaluated with interaction terms between the binary variable indicating the mandatory policy period and each race/ethnicity group. The model was adjusted for state-specific variables, such as percent of female infants and percent of private insurance. We identified 9,147 CCHD emergency hospitalizations. Among non-Hispanic Whites, there was a 22% (Confidence Interval [CI] 6%-36%) decline in CCHD emergency hospitalizations after implementation of mandated POS, on average. This decline was 65% less among non-Hispanic Blacks compared to non-Hispanic Whites. Our study detected an attenuated association with decreased number of emergency hospitalizations among Black compared to White infants. Further research is needed to clarify this disparity.

Abstract
INTRODUCTION The purpose of this study was to examine the association between prior emergency department (ED) visit or hospitalization and subsequent suicide attempt among homeless youth aged 10-17 years old. METHODS With New York statewide databases, a case-control design was conducted. Cases and controls were homeless patients with an ED visit or hospitalization due to suicide attempt (cases) or appendicitis (controls) between April and December. We examined ED and inpatient records for 90 days prior to the visit for suicide attempt or appendicitis. The primary exposure variable was prior healthcare utilization for any reason other than the following four reasons: mental health disorder, substance use, self-harm, and other injuries. Multivariable logistic regression models, with year fixed effect and hospital random effect, were used. RESULTS A total of 335 cases and 742 controls were identified. Cases had lower odds of prior healthcare utilization for any reason other than the four reasons listed above. (adjusted Odds Ratio [aOR]: 0.53, p-value = 0.03). CONCLUSIONS The association between prior healthcare utilization and decreased risk of suicide attempt among homeless youth may be due to comprehensive care provided during healthcare utilization. It may also reflect the presence of a social network that provided a protective effect.

Abstract
The suicide rate among adolescents and young adults in the United States increased 57% between 2007 and 2018, from 6.8 to 10.7 deaths per 100 000 individuals. Recent research characterized as alarming the increases in overall suicide rates among young Black and other racial/ethnic minority populations. To assess the temporal trends in overall suicide and firearm suicide mortality rates among non-Hispanic Black young adults, we conducted a sex-specific Joinpoint regression analysis to identify changing trends in these rates between 1999 and 2019. Data were obtained from the Centers for Disease Control and Prevention's Web-based Injury Statistics Query and Reporting System. Results showed an 84.5% increase in the firearm suicide rate among young Black men and a 76.9% increase among young Black women between 2013 and 2019. Additional research is needed to investigate potential population-level exposures during or before 2013 that may have influenced suicide and firearm suicide risk.

Abstract
ObjectiveTo assess differences in rates of postpartum hospitalisations among homeless women compared with non-homeless women.DesignCross-sectional secondary analysis of readmissions and emergency department (ED) utilisation among postpartum women using hierarchical regression models adjusted for age, race/ethnicity, insurance type during delivery, delivery length of stay, maternal comorbidity index score, other pregnancy complications, neonatal complications, caesarean delivery, year fixed effect and a birth hospital random effect.SettingNew York statewide inpatient and emergency department databases (2009–2014).Participants82 820 and 1 026 965 postpartum homeless and non-homeless women, respectively.Main outcome measuresPostpartum readmissions (primary outcome) and postpartum ED visits (secondary outcome) within 6 weeks after discharge date from delivery hospitalisation.ResultsHomeless women had lower rates of both postpartum readmissions (risk-adjusted rates: 1.4% vs 1.6%; adjusted OR (aOR) 0.87, 95% CI 0.75 to 1.00, p=0.048) and ED visits than non-homeless women (risk-adjusted rates: 8.1% vs 9.5%; aOR 0.83, 95% CI 0.77 to 0.90, p<0.001). A sensitivity analysis stratifying the non-homeless population by income quartile revealed significantly lower hospitalisation rates of homeless women compared with housed women in the lowest income quartile. These results were surprising due to the trend of postpartum hospitalisation rates increasing as income levels decreased.ConclusionsTwo factors likely led to lower rates of hospital readmissions among homeless women. First, barriers including lack of transportation, payment or childcare could have impeded access to postpartum inpatient and emergency care. Second, given New York State’s extensive safety net, discharge planning such as respite and sober living housing may have provided access to outpatient care and quality of life, preventing adverse health events. Additional research using outpatient data and patient perspectives is needed to recognise how the factors affect postpartum health among homeless women. These findings could aid in lowering readmissions of the housed postpartum population.

Abstract
Suicide remains the leading cause of death among homeless youth. We assessed differences in health-care utilization between homeless and nonhomeless youth presenting to the emergency department or hospital after a suicide attempt. New York Statewide Inpatient and Emergency Department Databases (2009-2014) were used to identify homeless and nonhomeless youth aged 10-17 who utilized health-care services following a suicide attempt. To evaluate associations with homelessness, we used logistic regression models for use of violent means, intensive care unit utilization, log-transformed linear regression models for hospitalization cost, and negative binomial regression models for length of stay. All models adjusted for individual characteristics with a hospital random effect and year fixed effect. We identified 18,026 suicide attempts with health-care utilization rates of 347.2 (95% confidence interval (CI): 317.5, 377.0) and 67.3 (95% CI: 66.3, 68.3) per 100,000 person-years for homeless and nonhomeless youth, respectively. Length of stay for homeless youth was statistically longer than that for nonhomeless youth (incidence rate ratio = 1.53, 95% CI: 1.32, 1.77). All homeless youth who visited the emergency department after a suicide attempt were subsequently hospitalized. This could suggest a higher acuity upon presentation among homeless youth compared with nonhomeless youth. Interventions tailored to homeless youth should be developed.

Abstract
OBJECTIVE Substance abuse, particularly among homeless youths, is a significant public health challenge in the United States. Detailed data about health care utilization resulting from this preventable behavior remain sparse. This study aimed to compare health care utilization rates related to substance abuse among homeless and nonhomeless youths. METHODS A secondary data analysis evaluated records of homeless and nonhomeless patients under age 25 with a primary diagnosis of substance abuse, identified in 2013 and 2014 New York Statewide Inpatient and Emergency Department (ED) Databases. Outcomes included ED visit rate, hospitalization rate, in-hospital mortality, cost, length of stay (LOS), intensive care unit (ICU) utilization, and revisit or readmission rate. Multivariable regression models with a year fixed effect and facility random effect were used to evaluate the association between homelessness and each outcome. RESULTS A total of 68,867 cases included hospitalization or an ED visit related to substance abuse (68,118 nonhomeless and 749 homeless cases). Rates of ED visits related to substance abuse were 9.38 and 4.96, while rates of hospitalizations related to substance abuse were 10.53 and 1.01 per 1,000 homeless and nonhomeless youths, respectively. Homeless patients were more likely to utilize and revisit the ICU, be hospitalized or readmitted, incur higher costs, and have longer LOS than nonhomeless youths (all p<0.01). CONCLUSIONS The hospitalization and ED visit rates related to substance abuse were 10 and two times higher among homeless youths compared with nonhomeless youths, respectively. Detailed observation is needed to clarify whether homeless youths receive high-quality care for substance abuse when necessary.

Abstract
IMPORTANCE A high cesarean delivery rate in US hospitals indicates the potential overuse of this procedure; however, underlying causes of the excessive use of cesarean procedures in the US have not been fully understood. OBJECTIVE To investigate the association between the probability of cesarean delivery at the patient-level and profit per procedure from cesarean deliveries. DESIGN, SETTING, AND PARTICIPANTS This observational, cross-sectional study used a nationally representative sample of hospital discharge data from women at low risk for cesarean birth who delivered newborns between 2010 and 2014 in the US. Data were gathered from the Nationwide Readmissions Database from the Healthcare Cost and Utilization Project, compiled by the Agency for Healthcare Research and Quality. Data cleaning and analyses were conducted between August 2019 and May 2020. EXPOSURES Hospital-level median value of profits from cesarean deliveries, defined as the difference between the charge and the cost for cesarean delivery calculated for each hospital. MAIN OUTCOMES AND MEASURES Our primary outcome was the individual-level probability of undergoing a cesarean delivery. We examined the association with the hospital-level median value of profits per procedure for cesarean delivery (defined as the difference between the charge and the cost for cesarean delivery) using hierarchical regression models adjusted for patient and hospital characteristics and year-fixed effects. RESULTS A total of 13 215 853 deliveries were included in our analyses (mean [SE] age, 27.4 [0] years), of which 2 202 632 (16.7%) were cesarean deliveries. After adjusting for potential confounders, pregnant women were more likely to have a cesarean birth when they delivered at hospitals with higher profits per procedure from cesarean deliveries. Women cared for at hospitals with the highest (adjusted odds ratio, 1.08; 95% CI, 1.02-1.14; P = .005) and second-highest profit quartiles (adjusted odds ratio, 1.07; 95% CI, 1.02-1.13; P = .007) had higher probabilities of a cesarean delivery compared with those cared for at hospitals in the lowest profit quartile. CONCLUSIONS AND RELEVANCE In this cross-sectional study of US nationally representative hospital discharge data, hospitals with higher profits per cesarean procedure were associated with an increased probability of delivering newborns through cesarean birth. These findings highlight the potential influence financial incentives play in determining a high cesarean delivery rate in the US.

Abstract
OBJECTIVE This study aims to describe differences in health care utilization between homeless and nonhomeless minors with diabetes. RESEARCH DESIGN AND METHODS Data from the Healthcare Cost and Utilization Project's Statewide Inpatient Database from New York for years 2009-2014 were examined to identify pediatric patients <18 years old with diabetes. Outcomes of interest included hospitalization rate, in-hospital mortality, admission through the emergency department (ED), diabetic ketoacidosis (DKA), hospitalization cost, and length of stay (LOS). Other variables of interest included age-group, race/ethnicity, insurance type, and year. Multivariate logistic regression models were used for in-hospital mortality, admission through ED, and DKA. Log-transformed linear regression models were used for hospitalization cost, and negative binomial regression models were used for LOS. RESULTS A total of 643 homeless and 10,559 nonhomeless patients were identified. The hospitalization rate was higher among homeless minors, with 3.64 per 1,000 homeless population compared with 0.38 per 1,000 in the nonhomeless population. A statistically significant higher readmission rate was detected among homeless minors (20.4% among homeless and 14.1% among nonhomeless, P < 0.01). Lower rates of DKA (odds ratio 0.75, P = 0.02), lower hospitalization costs (point estimate 0.88, P < 0.01), and longer LOS (incidence rate ratio 1.20, P < 0.01) were detected among homeless minors compared with nonhomeless minors. CONCLUSIONS This study found that among minors with diabetes, those who are homeless experience a higher hospitalization rate than the nonhomeless. Housing instability, among other environmental factors, may be targeted for intervention to improve health outcomes.

Abstract
Background Inadequate titers of pneumococcal antibody (PA) are commonly present among patients with recurrent respiratory infections. Objective We sought to determine the effect of the degree of inadequacy in baseline PA titers on the subsequent polysaccharide vaccine response, the incidence of sinusitis, and allergic conditions. Methods A total of 313 patients aged 6 to 70 years with symptoms of recurrent respiratory infections were classified by baseline-pPA (percentage of protective [≥1.3 µg/mL] PA serotypes/total tested serotypes) and postvaccination pPA (post-pPA): Group A (adequate baseline-pPA), Group B (inadequate baseline-pPA, adequate post-pPA, responders), and Group C (inadequate baseline-pPA, inadequate postpPA, nonresponders, specific antibody deficiency [SAD]). Immunity against Streptococcus pneumoniae was defined as adequate when the pPA was ≥70%. Each group and combined groups, Group AB (inadequate baseline-pPA), and Group BC (adequate post-pPA) were analyzed for demographics, history of sinusitis, recurrent sinusitis in the following year, allergic conditions, and association with inadequate individual serotype titers. Results Over 80% of patients with respiratory symptoms had inadequate baseline-pPA. Baseline-pPA and SAD prevalence are inversely related (odds ratio = 2.02, 95% CI: 1.15–3.57, P = .01). Inadequate serotype 3 antibody titer is highly associated with SAD (odds ratio = 2.02, 96% CI: 1.61–5.45, P < .01). The groups with inadequate pPA (Group B and C, or BC) had significantly higher percentage of patients with chronic rhinosinusitis (P < .001), allergic sensitization, and allergic rhinitis (P < .05). Group A contained higher percentage of patients with recurrent upper airway infections (P < .001). Conclusion Low baseline-pPA and low antibody titers to serotype 3 are highly associated with SAD, increased incidence of respiratory infections including CRS and allergic conditions.

Abstract
BACKGROUND Males and females are known to have varied responses to medical interventions. Our study aimed to determine the effect of sex on surgical outcomes after pyloromyotomy. MATERIALS AND METHODS Using the Kids' Inpatient Database for the years 2003-2012, we performed a serial, cross-sectional analysis of a nationally representative sample of all patients aged <1 y who underwent pyloromyotomy for hypertrophic pyloric stenosis. The primary predictor of interest was sex. Outcomes included mortality, in-hospital complications, cost, and length of stay. Regression models were adjusted by race, age group, comorbidity, complications, and whether operation was performed on the day of admission with region and year fixed effects. RESULTS Of 48,834 weighted operations, 81.8% were in males and 18.2% were in females. The most common reported race was white (47.3%) and most of the patients were ≥29 days old (72.5%). There was no difference in the odds of postoperative complications, but females had a significantly longer length of stay (incidence rate ratio, 1.28; 95% confidence interval [95% CI], 1.18-1.39; P ≤ 0.01), higher cost (5%, 95% CI, 1.02-1.08; P ≤ 0.01), and higher odds of mortality (odds ratio, 3.26; 95% CI, 1.52-6.98; P ≤ 0.01). CONCLUSIONS Our study demonstrated that females had worse outcomes after pyloromyotomy compared with males. These findings are striking and are important to consider when treating either sex to help set physician and family expectations perioperatively. Further studies are needed to determine why such differences exist and to develop targeted treatment strategies for both females and males with pyloric stenosis.

Abstract
BACKGROUND AND OBJECTIVES Asthma is widely prevalent among US children, particularly in homeless children, who often lack proper medication storage or the ability to avoid environmental triggers. In this study, we assess asthma-attributed health care use among homeless youth. We hypothesize that asthma hospitalization rates, symptom severity, and admission through the emergency department (ED) will be higher among homeless youth compared with nonhomeless youth. METHODS This secondary data analysis identified homeless and nonhomeless pediatric patients (<18 years old) with a primary diagnosis of asthma from New York statewide inpatient databases between 2009 and 2014. Hospitalization rate, readmission rate, admission through the ED, ventilation use, ICU admittance, hospitalization cost, and length of stay were measured. RESULTS We identified 71 837 asthma hospitalizations, yielding 73.8 and 2.3 hospitalizations per 1000 homeless and nonhomeless children, respectively. Hospitalization rates varied by nonhomeless income quartile, with low-income children experiencing higher rates (5.4) of hospitalization. Readmissions accounted for 16.0% of homeless and 12.5% of nonhomeless hospitalizations. Compared with nonhomeless patients, homeless patients were more likely to be admitted from the ED (odds ratio 1.96; 95% confidence interval: 1.82-2.12; P < .01), and among patients >5 years old, homeless patients were more likely to receive ventilation (odds ratio 1.45; 95% confidence interval: 1.01-2.09; P = .04). No significant differences were observed in ICU admittance, cost, or length of stay. CONCLUSIONS Homeless youth experience an asthma hospitalization rate 31 times higher than nonhomeless youth, with higher rates of readmission. Homeless youth live under uniquely challenging circumstances. Tailored asthma control strategies and educational intervention could greatly reduce hospitalizations.

Abstract
OBJECTIVE Regionalization directs patients to high-volume hospitals for specialized care. We investigated regionalization trends and outcomes in pediatric cardiac surgery. DATA SOURCES/STUDY SETTING Statewide inpatient data from eleven states between 2000 and 2012. STUDY DESIGN Mortality, length of stay (LOS), and cost were assessed using multivariable hierarchical regression with state and year fixed effects. Primary predictor was hospital case-volume, categorized into low-, medium-, and high-volume tertiles. DATA COLLECTION/EXTRACTION METHODS We used Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) to select pediatric cardiac surgery discharges. PRINCIPAL FINDINGS In total, 2841 (8.5 percent), 8348 (25.1 percent), and 22 099 (66.4 percent) patients underwent heart surgeries in low-, medium-, and high-volume hospitals. Mortality decreased over time, but remained higher in low- and medium-volume hospitals. High-volume hospitals had lower odds of mortality and cost than low-volume hospitals (odds ratio [OR] 0.59, P < 0.01, and relative risk [RR] 0.91, P < 0.01, respectively). LOS was longer for high- and medium-volume hospitals, compared to low-volume hospitals (high-volume: RR 1.18, P < 0.01; medium-volume: RR 1.05, P < 0.01). CONCLUSIONS Regionalization reduced mortality and cost, indicating fewer complications, but paradoxically increased LOS. Further research is needed to explore the full impact on health care utilization.

Abstract
OBJECTIVES Newborns hospitalized with unconjugated hyperbilirubinemia without critical comorbidities may receive intensive phototherapy (IP) in non-ICU levels of care, such as a mother-newborn unit, or ICU levels of care. Our aim was to compare outcomes between each level. METHODS Using hospital discharge data from 2005 to 2011 in New York's State Inpatient Database, we performed multivariate analyses to compare outcomes that included total cost of hospitalization, length of stay, 30-day readmission rate after IP, and the number of cases of death, exchange transfusion, and γ globulin infusion. We included term newborns treated with IP in their first 30 days of life and without diagnosis codes for other critical illnesses. Explanatory variables included level of care, sex, race, insurance type, presence or absence of hemolysis, hospital, volume of IP performed at each hospital, and year of hospitalization. RESULTS Ninety-nine percent of IP was delivered in non-ICU levels of care. Incidence of major complications was rare (≤0.1%). After adjusting for confounders, ICU level of care was not associated with difference in length of stay (relative risk: 1.2; 95% confidence interval [CI]: 0.91 to 1.15) or 30-day readmission rate (odds ratio: 0.74; 95% CI: 0.50 to 1.09) but was associated with 1.51 (95% CI: 1.47 to 1.56) times higher costs. CONCLUSIONS For otherwise healthy term newborns with jaundice requiring IP, most received treatment in a non-ICU level of care, and those in intensive care had no difference in outcomes but incurred higher costs. IP guideline authors may want to be more prescriptive about IP level of care to improve value.

Abstract
BACKGROUND/PURPOSE Despite policy efforts to support rural hospitals, little is known about the quality and safety of pediatric surgical care in geographically remote areas. Our aim was to determine the outcomes and costs of appendectomies at rural hospitals. METHODS The Kids' Inpatient Database (2003-2012) was queried for appendectomies in children <18 years at urban and rural hospitals. Outcomes (disease severity, laparoscopy, complications, length of stay (LOS), cost) were analyzed with bivariate and multivariable regression analysis. RESULTS Rural hospitals performed 13.6% of appendectomies. On multivariable analysis, rural hospitals were associated with higher negative appendectomy rates (OR 1.49, 95% CI 1.39-1.60, p < 0.001), decreased appendiceal perforation rates (OR 0.86, 95% CI 0.83-0.89, p < 0.001), less laparoscopy use (OR 0.48, 95% CI 0.47-0.50, p < 0.001), higher complication rates (OR 1.29, 95% CI 1.19-1.39, p < 0.001), shorter LOS (IRR 0.90, 95% CI 0.89-0.91, p < 0.001), and slightly increased costs (exponentiated log$ 1.02, 95% CI 1.01-1.02, p < 0.001) CONCLUSIONS: Rural hospitals care for fewer patients with advanced appendicitis but are associated with higher negative appendectomy rates, lower laparoscopy use, and higher complication rates. Additional studies are needed to identify factors that drive this disparity to improve the quality of pediatric surgical care in rural settings. TYPE OF STUDY Treatment/Cost Study (Outcomes).

Abstract
BACKGROUND Variations in the management of pediatric patients at children's hospitals (CHs) and non-CHs (NCHs) have been well described, especially within the trauma literature. However, little is known about the outcomes and costs of common general surgical procedures at NCHs. The purpose of this study was to evaluate the effect of CH designation on the outcomes and costs of appendectomy and cholecystectomy. METHODS The Kids' Inpatient Database (2003-2012) was queried for patients aged under 18 y who underwent appendectomy or cholecystectomy at CHs and NCHs. Outcomes analyzed included disease severity, complications, laparoscopy, length of stay (LOS), and cost. RESULTS Most of appendectomies and cholecystectomies were performed at NCHs. Overall, CHs cared for younger children were more likely to be teaching hospitals, had higher costs, and longer LOS. On multivariate analysis for appendectomies, CHs were associated with higher rates of perforated appendicitis (OR = 1.53, 95% CI = 1.42-1.66, P < 0.001), less complications (OR = 0.68, 95% CI = 0.61-0.75, P < 0.001), increased laparoscopy (OR = 2.93, 95% CI = 2.36-3.64, P < 0.001), longer LOS (RR = 1.13, 95% CI = 1.09-1.17, P < 0.001), and higher costs (exponentiated log $ = 1.19, 95% CI = 1.13-1.24, P < 0.001). Multivariate analysis for cholecystectomies revealed that CHs were associated with less laparoscopy (OR = 0.58, 95% CI = 0.50-0.67, P < 0.001), longer LOS (RR = 1.26, 95% CI = 1.19-1.34, P < 0.001), and higher costs (exponentiated log $ = 1.29, 95% CI = 1.22-1.37, P < 0.001) with similar complications. Independent predictors of LOS and cost included CH designation, negative appendectomy, perforated appendicitis, complications, younger age, black patients, and public insurance. CONCLUSIONS Variations in surgical management, outcomes, and costs after appendectomy and cholecystectomy exist between CHs and NCHs. CHs excelled in treating complicated appendicitis. NCHs effectively performed cholecystectomies. These differences in outcomes require further investigation to identify modifiable factors to optimize care across all hospitals for these common surgical diseases.

Abstract
BACKGROUND The purpose of our study was to assess the outcomes and costs of appendectomies performed at rural and urban hospitals. METHODS The National Inpatient Sample (2001-2012) was queried for appendectomies at urban and rural hospitals. Outcomes (disease severity, laparoscopy, complications, length of stay (LOS), and cost) were analyzed. RESULTS Rural patients were more likely to be older, male, white, and have Medicaid or no insurance. Rural hospitals were associated with higher negative appendectomy rates (OR = 1.26,95%CI = 1.18-1.34,p < 0.01), less laparoscopy use (OR = 0.65,95%CI = 0.58-0.72,p < 0.01), and slightly shorter LOS (OR = 0.98,95%CI = 0.97-0.99,p < 0.01). There was no consistent association with perforated appendicitis and no difference in complications or costs after adjusting for hospital volume. Yearly trends showed a significant increase in the cases utilizing laparoscopy each year at rural hospitals. CONCLUSIONS Rural appendectomies are associated with increased negative appendectomy rates and less laparoscopy use with no difference in complications or costs compared to urban hospitals.

Abstract
Variations in the management of adolescents at children's hospitals (CHs) and nonchildren's hospitals (NCHs) have been well described in the trauma literature. However, the effects of CH designation on outcomes after common general surgical procedures have not been investigated. The purpose of this study was to compare the outcomes and costs of adolescent cholecystectomies performed at CHs and NCHs. Within the California State Inpatient Database (2005–2011), we identified 8117 cholecystectomy patients aged 13 to 18 years at CHs and NCHs. Outcomes (laparoscopy, intraoperative cholangiogram, length of stay (LOS), and complications) and costs were analyzed. CHs cared for younger patients, more uninsured patients, and more black patients. NCHs were associated with higher laparoscopy use (95.7% vs 88.3%, P < 0.01), higher intra-operative cholangiogram rates (28.8% vs 11.9%, P < 0.001), shorter LOS (3.2 vs 5.0 days, P < 0.01), and lower costs by $5797 per patient ($11,219 vs $17,016, P < 0.01). Although there was no significant difference in overall complication rates, CHs had higher rates of infectious complications (2.0% vs 1.0%, P = 0.004). Adolescent cholecystectomies are safely performed at NCHs while achieving increased laparoscopy use, shorter LOS, and lower costs compared with CHs.

Abstract
BACKGROUND Highly-competent patient care is paramount to medicine. Quality training and patient accessibility to physicians with a wide range of specializations is essential. Yet, poor quality of life for physicians cannot be ignored, being detrimental to patient care and leading to personnel leaving the medical profession. In 2004, the Japanese government reformed postgraduate training for medical graduates, adding a 2-year, hands-on rotation through different specialties before the specialization residency was begun. Residents could now choose practice location, but it sparked concerns that physician distribution disparities had been created. Japanese media reported that residents were choosing specialties deemed to offer a higher quality of life, like Ophthalmology or Dermatology, over underserved areas like Obstetrics or Cardiology. To explore the consequences of Japan's policy efforts, through the residency reform in 2004, to improve physician training, analyzing ophthalmologist supply and distribution in the context of providing the best possible patient care and access while maintaining physician quality of life. METHODS Using secondary data, we analyzed changes in ophthalmologist supply at the secondary tier of medical care (STM). We applied ordinary least-squares regression models to ophthalmologist density to reflect community factors such as residential quality and access to further professional development, to serve as predictors of ophthalmologist supply. Coefficient equality tests examined predictor differences before and after 2004. Similar analyses were conducted for all physicians excluding ophthalmologists (other physicians). Ophthalmologist coverage in top and bottom 10% of STMs revealed supply inequalities. RESULTS Change in ophthalmologist supply was inversely associated with baseline ophthalmologist density before (P < .01) and after (P = .01) 2004. Changes in other physician supply were not associated with baseline other physician density before 2004 (P = 0.5), but positively associated after 2004 (P < .01). Inequalities between top and bottom 10% of ophthalmologist supply in STMs were large, with best-served areas maintaining roughly five times greater coverage than least-served areas. However, inequalities gradually declined between 1998 and 2012. CONCLUSIONS Ophthalmologist supply increased both before and after the 2004 reform, yet contrary to media reports, proceeded at a lesser rate than supply increases for other physicians. After 2004, geographical disparities decreased for ophthalmologists, while increasing for other physicians.
