Association of State Medicaid Expansion Status With Low Birth Weight and Preterm Birth.

Importance: Low birth weight and preterm birth are associated with adverse consequences including increased risk of infant mortality and chronic health conditions. Black infants are more likely than white infants to be born prematurely, which has been associated with disparities in infant mortality and other chronic conditions. Objective: To evaluate whether Medicaid expansion was associated with changes in rates of low birth weight and preterm birth outcomes, both overall and by race/ethnicity. Design, Setting, and Participants: Using US population-based data from the National Center for Health Statistics Birth Data Files (2011-2016), difference-in-differences (DID) and difference-in-difference-in-differences (DDD) models were estimated using multivariable linear probability regressions to compare birth outcomes among infants in Medicaid expansion states relative to non-Medicaid expansion states and changes in relative disparities among racial/ethnic minorities for singleton live births to women aged 19 years and older. Exposures: State Medicaid expansion status and racial/ethnic category. Main Outcomes and Measures: Preterm birth (<37 weeks' gestation), very preterm birth (<32 weeks' gestation), low birth weight (<2500 g), and very low birth weight (<1500 g). Results: The final sample of 15 631 174 births (white infants: 8 244 924, black infants: 2 201 658, and Hispanic infants: 3 944 665) came from the District of Columbia and 18 states that expanded Medicaid (n = 8 530 751) and 17 states that did not (n = 7 100 423). In the DID analyses, there were no significant changes in preterm birth in expansion relative to nonexpansion states (preexpansion to postexpansion period, 6.80% to 6.67% [difference: -0.12] vs 7.86% to 7.78% [difference: -0.08]; adjusted DID: 0.00 percentage points [95% CI, -0.14 to 0.15], P = .98), very preterm birth (0.87% to 0.83% [difference: -0.04] vs 1.02% to 1.03% [difference: 0.01]; adjusted DID: -0.02 percentage points [95% CI, -0.05 to 0.02], P = .37), low birth weight (5.41% to 5.36% [difference: -0.05] vs 6.06% to 6.18% [difference: 0.11]; adjusted DID: -0.08 percentage points [95% CI, -0.20 to 0.04], P = .20), or very low birth weight (0.76% to 0.72% [difference: -0.03] vs 0.88% to 0.90% [difference: 0.02]; adjusted DID: -0.03 percentage points [95% CI, -0.06 to 0.01], P = .14). Disparities for black infants relative to white infants in Medicaid expansion states compared with nonexpansion states declined for all 4 outcomes, indicated by a negative DDD coefficient for preterm birth (-0.43 percentage points [95% CI, -0.84 to -0.02], P = .05), very preterm birth (-0.14 percentage points [95% CI, -0.26 to -0.02], P = .03), low birth weight (-0.53 percentage points [95% CI, -0.96 to -0.10], P = .02), and very low birth weight (-0.13 percentage points [95% CI, -0.25 to -0.01], P = .04). There were no changes in relative disparities for Hispanic infants. Conclusions and Relevance: Based on data from 2011-2016, state Medicaid expansion was not significantly associated with differences in rates of low birth weight or preterm birth outcomes overall, although there were significant improvements in relative disparities for black infants compared with white infants in states that expanded Medicaid vs those that did not.

Are community health workers more effective in identifying persons in need of home and community-based long-term services than standard-passive approaches.

Consumers prefer home and community-based long-term care (LTC) services (HCBS) but lack information on those services. We examined the use of community health workers (CHWs) to find and help Medicaid beneficiaries with unmet LTC needs access HCBS compared to standard HCBS outreach approaches. We found that CHWs were very effective at finding persons with greater needs and were better able to help them access a greater range of HCBS services. We also found that five times fewer HCBS beneficiaries helped by CHWs had to use nursing home care services than those not helped by the CHWs despite the fact that their health status was poorer than those not helped by the CHWs. Our study provides evidence of the effectiveness of CHWs for HCBS service awareness and navigation.

Financial Performance of Hospitals in the Mississippi Delta Region Under the Hospital Readmissions Reduction Program and Hospital Value-based Purchasing Program.

BACKGROUND: Previous studies showed that the Hospital Readmissions Reduction Program (HRRP) and the Hospital Value-based Purchasing Program (HVBP) disproportionately penalized hospitals caring for the poor. The Mississippi Delta Region (Delta Region) is among the most socioeconomically disadvantaged areas in the United States. The financial performance of hospitals in the Delta Region under both HRRP and HVBP remains unclear. OBJECTIVE: To compare the differences in financial performance under both HRRP and HVBP between hospitals in the Delta Region (Delta hospitals) and others in the nation (non-Delta hospitals). RESEARCH DESIGN: We used a 7-year panel dataset and applied difference-in-difference models to examine operating and total margin between Delta and non-Delta hospitals in 3 time periods: preperiod (2008-2010); postperiod 1 (2011-2012); and postperiod 2 (2013-2014). RESULTS: The Delta hospitals had a 0.89% and 4.24% reduction in operating margin in postperiods 1 and 2, respectively, whereas the non-Delta hospitals had 1.13% and 1% increases in operating margin in postperiods 1 and 2, respectively. The disparity in total margins also widened as Delta hospitals had a 1.98% increase in postperiod 1, but a 0.30% reduction in postperiod 2, whereas non-Delta hospitals had 1.27% and 2.28% increases in postperiods 1 and 2, respectively. CONCLUSIONS: The gap in financial performance between Delta and non-Delta hospitals widened following the implementation of HRRP and HVBP. Policy makers should modify these 2 programs to ensure that resources are not moved from the communities that need them most.

Childhood Respiratory Morbidity after Late Preterm and Early Term Delivery: a Study of Medicaid Patients in South Carolina.

BACKGROUND: There is a growing body of research documenting an increased risk of neonatal morbidity for late preterm infants (LPI, 34(0/7) weeks to 36(6/7) weeks) and early term infants (ETI, 37(0/7) weeks to 38(6/7) weeks) compared with term infants (TI, 39(0/7) to 41(6/7) ); however, there has been little research on outcomes beyond the first year of life. In this study, we examined respiratory outcomes of LPI and ETI in early childhood. METHODS: South Carolina Medicaid claims data for maternal delivery and infant birth hospitalisations were linked to vital records data for the years 2000 through 2003. Medicaid claims for all infants were then followed until their fifth birthday or until a break in their eligibility. Infants born between 34(0/7) and 41(6/7) weeks were eligible. Infants with congenital anomaly, birthweight below 500 g or above 6000 g, and multiple births were excluded. We fit Cox proportional hazard models from which adjusted hazard ratio (HR) and 95% confidence interval (CI) were derived. RESULTS: A total of 3476 LPI, 12 398 ETI, and 25 975 term infants were included. Both LPI and ETI were associated with an increased risk for asthma (LPI: HR 1.24, 95% CI 1.10, 1.40; ETI: HR 1.12, 95% CI 1.06, 1.19), and bronchitis (LPI: HR 1.15, 95% CI 1.00, 1.34; ETI: HR 1.13, 95% CI 1.05, 1.2) at 3 to 5 years of age. CONCLUSIONS: Late preterm infants and early term infants are at increased risk for asthma and bronchitis.

Birth statistics of high birth weight infants (macrosomia) in Arkansas.

The incidence of macrosomia in Arkansas was relatively unchanged from 2004 to 2010 with the incidence being 7.7%. Some risk factors identified through the analysis of hospital discharge data include male fetus, gestational age, maternal weight gain during pregnancy, and pregestational and gestational diabetes.

Vulvodynia in Arkansas: a survey of Arkansas gynecologists' practice experience and management of vulvar pain.

The objective of this survey was to determine the level of experience OB/GYN (Obstetrics & Gynecology) physicians in the state of Arkansas have in seeing and managing patients with vulvar pain, commonly known as vulvodynia. The 8 question, anonymous survey was mailed to Arkansas OB/GYN physicians. The survey assessed the experience of the providers, the age range of their patients, and whether or not they treat and/or refer. Thirty of 182 surveys were returned for a rate of 16.4%. The survey revealed that physicians are moderately comfortable treating vulvodynia within their practice and refer mostly for treatment failure.

Associations of family-centered care with health care outcomes for children with special health care needs.

The objective of this study is to examine the association of family-centered care (FCC) with specific health care service outcomes for children with special health care needs (CSHCN). The study is a secondary analysis of the 2005-2006 National Survey of Children with Special Health Care Needs. Receipt of FCC was determined by five questions regarding how well health care providers addressed family concerns in the prior 12 months. We measured family burden by reports of delayed health care, unmet need, financial costs, and time devoted to care; health status, by stability of health care needs; and emergency department and outpatient service use. All statistical analyses used propensity score-based matching models to address selection bias. FCC was reported by 65.6% of respondents (N = 38,915). FCC was associated with less delayed health care (AOR: 0.56; 95% CI: 0.48, 0.66), fewer unmet service needs (AOR: 0.53; 95% CI: 0.47, 0.60), reduced odds of ≥1 h/week coordinating care (AOR: 0.83; 95% CI: 0.74, 0.93) and reductions in out of pocket costs (AOR: 0.88; 95% CI: 0.80, 0.96). FCC was associated with more stable health care needs (AOR: 1.11; 95% CI: 1.01, 1.21), reduced odds of emergency room visits (AOR: 0.90; 95% CI: 0.82, 0.99) and increased odds of doctor visits (AOR: 1.25; 95% CI: 1.14, 1.37). Our study demonstrates associations of positive health and family outcomes with FCC. Realizing the health care delivery benefits of FCC may require additional encounters to build key elements of trust and partnership.

Improved Health and Insurance Status Among Cigarette Smokers After Medicaid Expansion, 2011-2016.

OBJECTIVES: The high concentration of smokers among subgroups targeted by the Affordable Care Act and the historically worse health and lower access to health care among smokers warrants an evaluation of how Medicaid expansion affects smokers. We evaluated the impact of Medicaid expansion on smoking behavior, access to health care, and health of low-income adults, and we compared outcomes of all low-income people with outcomes of low-income current smokers by states' Medicaid expansion status. METHODS: We obtained data from the Behavioral Risk Factor Surveillance System (2011-2016) for low-income adults aged 18-64. We estimated multivariable linear ordinary least squares probability models using a quasi-experimental difference-in-difference approach to compare smoking behavior, access to health care, and health between people in expansion states and nonexpansion states and, specifically, on low-income adults and the subgroup of low-income current smokers. RESULTS: Compared with low-income smokers in nonexpansion states, low-income smokers in expansion states were 7.6 percentage points (95% confidence interval [CI], 5.7-9.6; P < .001) more likely to have health insurance, 3.2 percentage points (95% CI, 1.3-5.2; P = .001) more likely to report good or better health, and 2.0 percentage points (95% CI, -3.9 to -0.1; P = .044) less likely to have cost-related barriers to care. Health and insurance gains among current smokers in expansion states were larger relative to health gains (1.6 percentage points; 95% CI, 0.5-2.7; P = .003) and insurance gains (4.6 percentage points; 95% CI, 3.5-5.8; P < .001) of all low-income adults in these states. CONCLUSIONS: Greater improvements among low-income smokers in Medicaid expansion states compared with nonexpansion states could influence future smoking behaviors and warrant longer-term monitoring. Additionally, health and insurance gains among low-income smokers in expansion states suggest the potential for Medicaid expansion to improve health among smokers compared with nonsmokers.

Comparison of in-hospital and longer-term outcomes of hybrid and Norwood stage 1 palliation of hypoplastic left heart syndrome.

OBJECTIVES: The hybrid approach for the initial management of hypoplastic left heart syndrome shifts the risks of major open surgery from the vulnerable neonatal period to an older age. This study determined differences between the hybrid and the standard Norwood procedures in postoperative in-hospital mortality, renal failure, and survival to at least 2 years of age. METHODS: Data from the Pediatric Health Information System, a detailed hospital discharge database of 43 freestanding children's hospitals, were analyzed. The Pediatric Health Information System includes demographic information, diagnosis, and procedure and clinical service data. Instrumental variable regression techniques were used to estimate the predicted probability of in-hospital mortality, renal failure, and survival to 24 months of age for infants with hypoplastic left heart syndrome who received a hybrid or Norwood procedure. The statistical models controlled for demographics and comorbid chromosomal anomalies. RESULTS: A total of 3654 infants with hypoplastic left heart syndrome underwent intervention from 1998 to 2012. Of these, 242 underwent the hybrid approach and the remainder underwent the Norwood procedure. Instrumental variable models showed significantly reduced odds of patients who underwent the hybrid approach being diagnosed with renal failure (adjusted risk ratio [ARR], 0.48; 95% confidence interval [CI], 0.26-0.89); increased odds of surviving initial hospitalization (ARR, 1.28; 95% CI, 1.06-1.55); increased odds of survival, indicated by readmissions more than 6 months after initial hospitalization (ARR, 1.53; 95% CI, 1.05-2.22); and a decrease in length of stay by 20 days for the initial surgical hospitalization (95% CI, -27.4 to -13.9). CONCLUSIONS: The short term hospital-based outcomes and longer-term survival outcomes of the hybrid approach for hypoplastic left heart syndrome may be better than those of the Norwood procedure.

Increasing prevalence of medically complex children in US hospitals.

OBJECTIVE: In this study we used national data to determine changes in the prevalence of hospital admissions for medically complex children over a 15-year period. PATIENTS AND METHODS: Data from the Nationwide Inpatient Sample, a component of the Healthcare Cost and Utilization Project, was analyzed in 3-year increments from 1991 to 2005 to determine national trends in rates of hospitalization of children aged 8 days to 4 years with chronic conditions. Discharge diagnoses from the Nationwide Inpatient Sample were grouped into 9 categories of complex chronic conditions (CCCs). Hospitalization rates for each of the 9 CCC categories were studied both individually and in combination. Trends of children hospitalized with 2 specific disorders, cerebral palsy (CP) and bronchopulmonary dysplasia, with additional diagnoses in more than 1 CCC category were also examined. RESULTS: Hospitalization rates of children with diagnoses in more than 1 CCC category increased from 83.7 per 100,000 (1991-1993) to 166 per 100 000 (2003-2005) (P[r]<.001). The hospitalization rate of children with CP plus more than 1 CCC diagnosis increased from 7.1 to 10.4 per 100 000 (P=.002), whereas the hospitalization rates of children with bronchopulmonary dysplasia plus more than 1 CCC diagnosis increased from 9.8 to 23.9 per 100,000 (P<.001). CONCLUSIONS: Consistent increases in hospitalization rates were noted among children with diagnoses in multiple CCC categories, whereas hospitalization rates of children with CP alone have remained stable. The relative medical complexity of hospitalized pediatric patients has increased over the past 15 years.

Late preterm infants: birth outcomes and health care utilization in the first year.

OBJECTIVE: To distinguish the effects of late preterm birth from the complications associated with the causes of delivery timing, this study used propensity score-matching methods on a statewide database that contains information on both mothers and infants. METHODS: Data for this study came from Arkansas Medicaid claims data linked to state birth certificate data for the years 2001 through 2005. We excluded all multiple births, infants with birth defects, and infants at <33 weeks of gestation. Late preterm infants (LPIs) (34 to 36 weeks of gestation) were matched with term infants (37-42 weeks of gestation) according to propensity scores, on the basis of infant, maternal, and clinical characteristics. RESULTS: A total of 5188 LPIs were matched successfully with 15303 term infants. LPIs had increased odds of poor outcomes during their birth hospitalization, including a need for mechanical ventilation (adjusted odds ratio [aOR]: 1.31 [95% confidence interval [CI]: 1.01-1.68]), respiratory distress syndrome (aOR: 2.84 [95% CI: 2.33-3.45]), and hypoglycemia (aOR: 1.60 [95% CI: 1.26-2.03]). Outpatient and inpatient Medicaid expenditures in the first year were both modestly higher (outpatient, adjusted marginal effect: $108 [95% CI: $58-$158]; inpatient, $597 [95% CI: $528-$666]) for LPIs. CONCLUSIONS: LPIs are at increased risk of poor health-related outcomes during their birth hospitalization and of increased health care utilization during their first year.

Trends in hospitalizations for neonatal jaundice and kernicterus in the United States, 1988-2005.

CONTEXT AND OBJECTIVE: Recent reports have raised global concerns about a reemergence of kernicterus. Accurate information on the incidence of kernicterus is unavailable because of the rarity of the condition and the lack of a systematic surveillance strategy. We used nationally representative hospital discharge data to evaluate trends in the diagnosis and management of neonatal jaundice and the incidence of kernicterus in relation to the American Academy of Pediatrics hyperbilirubinemia clinical practice guideline. PATIENTS AND METHODS: The data came from the Healthcare Cost and Utilization Project family of databases. The Nationwide Inpatient Sample and the Kids' Inpatient Database were combined to generate trend data for the years 1988-2005. All neonatal discharges with primary or secondary International Classification of Diseases, Ninth Revision, Clinical Modification diagnoses codes for jaundice or kernicterus occurring within the first 30 days of life were selected with population incidence rates calculated from estimates of term and preterm newborn hospitalizations derived from the Healthcare Cost and Utilization Project data. To increase the reliability of identified kernicterus hospitalizations, newborns with a diagnosis of kernicterus and a procedure code for phototherapy or exchange transfusion were included as cases. RESULTS: Hospital diagnosis codes for kernicterus likely included a substantial number of rule-out cases, because approximately 70% did not include a procedure code for phototherapy or exchange transfusion. Including only cases with a procedure code for phototherapy or exchange transfusion resulted in 2.7 per 100000 diagnosed with kernicterus over the entire study period. A diagnosis code for jaundice was recorded for 15.6% of newborns. The diagnosis of jaundice and kernicterus differed according to race and gender. Rates also were elevated in preterm relative to term infants for both jaundice and kernicterus. Trends in diagnosis for newborn jaundice were u-shaped, with rates falling in the years before the initial American Academy of Pediatrics guideline (1988-1993) and increasing in the years after publication of the guideline (1997-2005). In contrast, the number of newborn hospitalizations with a diagnosis of kernicterus generally declined throughout the study period. Most of the decline in hospitalizations for term infants with a diagnosis of kernicterus occurred before and immediately after publication of the 1994 guideline, going from 5.1 per 100000 in 1988 to 1.5 per 100000 in the years from 1994 to 1996 and has since remained constant. CONCLUSIONS: Nationally representative hospital data indicate a declining incidence of hospitalizations with a diagnosis of kernicterus in newborn infants over the period 1988-2005. The decline occurred before and immediately after publication of the 1994 American Academy of Pediatrics guideline on hyperbilirubinemia. Epidemiologic findings were mostly consistent with other studies. Healthcare Cost and Utilization Project data provide an important system for monitoring hospitalizations of uncommon newborn conditions such as kernicterus.
