RESUMEN

OBJECTIVE: To test the hypothesis that newborn infants cared for in hospitals with greater utilization of neonatal intensive care experienced fewer postdischarge adverse events. STUDY DESIGN: We developed 3 retrospective population-based cohorts of Texas Medicaid insured singletons born in 2010-2014 (very low birth weight [VLBW n = 11 139], late preterm [n = 57 509], and non-preterm [n = 664 447]) who received care in higher volume hospitals with level III/IV neonatal intensive care units (NICUs). Measures of NICU care were hospital-level risk adjusted NICU admission rates, special care days (days of nonroutine care) per infant, and the percent of intensive (highest billable care code) special care days. The units of analysis were hospitals (n = 80) and the primary outcome was an adverse event, (defined as admission, emergency department visit, or death) within 30 days postdischarge. RESULTS: Higher use of NICU care at a hospital level was not associated with lower postdischarge 30-day adverse event. Infants cared for in hospitals with above vs below median special care day rates experienced slightly higher postdischarge adverse event per 100 infants (VLBW: 14.01 [95% CI 12.74-15.27] vs 11.84 [10.52-13.16], P < .05; late preterm: 7.33 [6.68-7.97] vs 6.28 [5.87-6.69], P < .01; non-preterm: 4.47 [4.17-4.76] vs 3.97 [3.75-4.18], P < .01). Weak positive associations (Pearson correlations of 0.31-0.37, P < .01) were observed for adverse event with special care days; in no instance was a negative association observed between NICU utilization and adverse event. CONCLUSION: Higher utilization of NICU care was not associated with lower rates of short-term events suggesting that there may be opportunities to safely decrease admission rates and length of NICU stays.

RESUMEN

OBJECTIVE: To assess the contribution of maternal and newborn characteristics to variation in neonatal intensive care use across regions and hospitals. STUDY DESIGN: This was a retrospective population-based live birth cohort of newborn infants insured by Texas Medicaid in 2010-2014 with 2 subcohorts: very low birth weight (VLBW) singletons and late preterm singletons. Crude and risk-adjusted neonatal intensive care unit (NICU) admission rates, intensive and intermediate special care days, and imaging procedures were calculated across Neonatal Intensive Care Regions (n = 21) and hospitals (n = 100). Total Medicaid payments were calculated. RESULTS: Overall, 11.5% of live born, 91.7% of VLBW, and 37.6% of infants born late preterm were admitted to a NICU, receiving an average of 2 days, 58 days, and 5 days of special care with payments per newborn inpatient episode of $5231, $128 075, and $10 837, respectively. There was little variation across regions and hospitals in VLBW NICU admissions but marked variation for NICU admissions in late preterm newborn infants and for special care days and imaging rates in all cohorts. The variation decreased slightly after health risk adjustment. There was moderate substitution of intermediate for intensive care days across hospitals (Pearson r VLBW -0.63 P < .001; late preterm newborn -0.53 P < .001). CONCLUSIONS: Across all risk groups, the variation in NICU use was poorly explained by differences in newborn illness levels and is likely to indicate varying practice styles. Although the "right" rates are uncertain, it is unlikely that all of these use patterns represent effective and efficient care.

RESUMEN

OBJECTIVE: To characterize geographic variation in neonatal intensive care unit (NICU) admission rates across the entire birth cohort and evaluate the relationship between regional bed supply and NICU admission rates. STUDY DESIGN: This was a population-based, cross-sectional study. 2013 US birth certificate and 2012 American Hospital Association data were used to assign newborns and NICU beds to neonatal intensive care regions. Descriptive statistics of admission rates were calculated across neonatal intensive care regions. Multilevel logistic regression was used to examine the relationship between bed supply and individual odds of admission, with adjustment for maternal and newborn characteristics. RESULTS: Among 3 304 364 study newborns, the NICU admission rate was 7.2 per 100 births and varied across regions for all birth weight categories. IQRs in admission rates were 84.5-93.2 per 100 births for 500-1499 g, 35.3-46.1 for 1500-2499 g, and 3.5-5.5 for ≥2500 g. Adjusted odds of admission for newborns of very low birth weight were unrelated to regional bed supply; however, newborns ≥2500 g in regions with the highest NICU bed supply were significantly more likely to be admitted to a NICU than those in regions with the lowest (aOR 1.20 [1.03-1.40]). CONCLUSIONS: There is persistent underuse of NICU care for newborns of very low birth weight that is not associated with regional bed supply. Among larger newborns, we find evidence of supply-sensitive care, raising concerns about the potential overuse of expensive and unnecessary care. Rather than improving access to needed care, NICU expansion may instead further deregionalize neonatal care, exacerbating underuse.

RESUMEN

OBJECTIVES: To compare rates of typmanostomy tube insertions for otitis media with effusion with estimates of need in 2 countries. STUDY DESIGN: This cross-sectional analysis used all-payer claims to calculate rates of tympanostomy tube insertions for insured children ages 2-8 years (2007-2010) across pediatric surgical areas (PSA) for Northern New England (NNE; Maine, Vermont, and New Hampshire) and the English National Health Service Primary Care Trusts (PCT). Rates were compared with expected rates estimated using a Monte Carlo simulation model that integrates clinical guidelines and published probabilities of the incidence and course of otitis media with effusion. RESULTS: Observed rates of tympanostomy tube placement varied >30-fold across English PCT (N = 150) and >3-fold across NNE PSA (N = 30). At a 25 dB hearing threshold, the overall difference in observed to expected tympanostomy tubes provided was -3.41 per 1000 child-years in England and -0.01 per 1000 child-years in NNE. Observed incidence of insertion was less than expected in 143 of 151 PCT, and was higher than expected in one-half of the PSA. Using a 20 dB hearing threshold, there were fewer tube insertions than expected in all but 2 England and 7 NNE areas. There was an inverse relationship between estimated need and observed tube insertion rates. CONCLUSIONS: Regional variations in observed tympanostomy tube insertion rates are unlikely to be due to differences in need and suggest overall underuse in England and both overuse and underuse in NNE.

RESUMEN

OBJECTIVE: To measure prescription use intensity and regional variation of psychotropic and 2 important nonpsychotropic drug groups among children with autism spectrum disorders (ASDs) compared with children in the general population. STUDY DESIGN: Cross-sectional study of ambulatory prescription fills from Maine, Vermont, and New Hampshire all-payer administrative data, 2007-2010. RESULTS: Overall there were 13,100 children diagnosed with ASD (34,584 person years [PYs]) and 936,721 (1.7 million PYs) without ASD diagnosis. The overall prescription fill rate was 16.6 per PY in children with ASD and 4.1 per PY in the general population. Psychotropic use among children with ASDs was 9-fold the general population rate (7.80 vs 0.85 fills per PY); these children comprised 2.0% of the pediatric population but received 15.6% of psychotropics. Nonpsychotropic drug use was also higher in the population with ASD, particularly the youngest: among those under age 3 years, antibiotic use was 2-fold and antacid use nearly 5-fold the general population rate (3.2 vs 1.4 and 1.0 vs 0.2 per PY, respectively). Among children with ASDs, prescription use varied substantially across hospital service areas, as much as 3-fold for antacids and alpha agonists, more than 4-fold for benzodiazepines (5th to 95th percentile). CONCLUSIONS: The overall psychotropic and nonpsychotropic prescription intensity among children with ASDs is characterized by broad regional variation, suggesting diverse provider responses to pharmacotherapeutic uncertainty. This variation highlights a need for more research, practice-based learning, and shared decision making with caregivers surrounding therapy for children with ASDs.

RESUMEN

Importance: Knowledge of health outcomes among opioid-exposed infants is limited, particularly for those not diagnosed with neonatal opioid withdrawal syndrome (NOWS). Objectives: To describe infant mortality among opioid-exposed infants and identify how mortality risk differs in opioid-exposed infants with and without a diagnosis of NOWS compared with infants without opioid exposure. Design, Setting, and Participants: A retrospective cohort study of maternal-infant dyads was conducted, linking health care claims with vital records for births from January 1, 2010, to December 31, 2014, with follow-up of infants until age 1 year (through 2015). Maternal-infant dyads were included if the infant was born in Texas at 22 to 43 weeks' gestational age to a woman aged 15 to 44 years insured by Texas Medicaid. Data analysis was performed from May 2019 to October 2020. Exposure: The primary exposure was prenatal opioid exposure, with infants stratified by the presence or absence of a diagnosis of NOWS during the birth hospitalization. Main Outcomes and Measures: Risk of infant mortality (death at age <365 days) was examined using Kaplan-Meier and log-rank tests. A series of logistic regression models was estimated to determine associations between prenatal opioid exposure and mortality, adjusting for maternal and neonatal characteristics and clustering infants at the maternal level to account for statistical dependence owing to multiple births during the study period. Results: Among 1 129 032 maternal-infant dyads, 7207 had prenatal opioid exposure, including 4238 diagnosed with NOWS (mean [SD] birth weight, 2851 [624] g) and 2969 not diagnosed with NOWS (mean [SD] birth weight, 2971 [639] g). Infant mortality was 20 per 1000 live births for opioid-exposed infants not diagnosed with NOWS, 11 per 1000 live births for infants with NOWS, and 6 per 1000 live births in the reference group (P < .001). After adjusting for maternal and neonatal characteristics, mortality in infants with a NOWS diagnosis was not significantly different from the reference population (odds ratio, 0.82; 95% CI, 0.58-1.14). In contrast, the odds of mortality in opioid-exposed infants not diagnosed with NOWS was 72% greater than the reference population (odds ratio, 1.72; 95% CI, 1.25-2.37). Conclusions and Relevance: In this study, opioid-exposed infants appeared to be at increased risk of mortality, and the treatments and supports provided to those diagnosed with NOWS may be protective. Interventions to support opioid-exposed maternal-infant dyads are warranted, regardless of the perceived severity of neonatal opioid withdrawal.

RESUMEN

BACKGROUND: The success of neonatal intensive care in improving outcomes for critically ill neonates led to rapid growth of NICU use in the United States, despite a relatively stable birth cohort. Less is known about NICU use among late-preterm and term infants, although recent studies have observed wide variation in their care patterns. In this study, we measure special care days (SCDs) (intermediate or intensive), length of stay, and readmission rates among low-risk neonates across regions within 2 states. METHODS: In this retrospective cohort study, we analyzed data from Massachusetts (all payer claims) and Texas (BlueCross BlueShield) from 2009 to 2012. A low-risk cohort was defined by identifying newborns with diagnostic codes indicating a gestational age ≥35 weeks and birth weight ≥1500 g and excluding infants with diagnoses and procedures generally necessitating nonroutine care. Outcomes were measured across neonatal intensive care regions by diagnosis and payer type. RESULTS: We identified 255 311 low-risk newborns. SCD use varied nearly sixfold across neonatal intensive care regions. Use was highest among commercially insured Texas infants (8.42 per 100), followed by Medicaid-insured Massachusetts infants (6.67 per 100) and commercially insured Massachusetts infants (5.15 per 100). Coefficients of variation indicated high variation within each payer-specific cohort and moderate to high variation across each condition. No consistent relationship between regional SCD use and 30-day readmissions was identified. CONCLUSIONS: Use of NICU services varied widely across regions in this cohort of low-risk infants. Further investigation is needed to delineate outcomes associated with patterns of care received by this population.

RESUMEN

BACKGROUND: Despite the frequency of pediatric prescribing little is known about practice differences across small geographic regions and payer type (Medicaid and commercial). OBJECTIVE: The goal of this research was to quantify variation in prescription drug use among northern New England children. METHODS: Northern New England, all-payer administrative data (2007-2010) permitted study of prescriptions for 949 821 children ages 0 to 17 years (1.75 million person-years [PYs]; 54% Medicaid, 46% commercial). Age- and gender adjusted overall and drug group-specific prescription use was quantified according to payer type (Medicaid or commercial) and within payer type across 69 hospital service areas (HSAs). We measured prescription fills per PY (rate) and annual, mean percentage of the population with any drug group-specific fills (prevalence). RESULTS: Overall mean annual prescriptions per PY were 3.4 (commercial) and 5.5 (Medicaid). Generally, these payer type differences were smaller than HSA-level variation within payer type. HSA-level rates of attention-deficit/hyperactivity disorder drug use (5th-95th percentile) varied twofold in Medicaid and more than twofold in commercially insured children; HSA-level antidepressant use varied more than twofold within each payer type. Antacid use varied threefold across HSAs and was highest in infants where commercial use paradoxically exceeded Medicaid. Prevalence of drug use varied as much as rates across HSAs. CONCLUSIONS: Prescription use was higher among Medicaid-insured than commercially insured children. Regional variation generally exceeded payer type differences, especially for drugs used in situations of diagnostic and therapeutic uncertainty. Efforts should advance best pediatric prescribing discussions and shared decision-making.
