False-Positive Newborn Screening Result and Future Health Care Use in a State Medicaid Cohort

OBJECTIVE: To compare health care visit rates between infants with false-positive and those with normal newborn screening (NBS) results. PATIENTS AND METHODS: We analyzed administrative claims of Medicaid-enrolled infants born in Michigan in 2006 and calculated the average number of outpatient, emergency department, and hospital visits for infants aged 3 to 12 months according to NBS results. We calculated an adjusted incidence rate ratio for each visit category, adjusting for covariates and accounting for interaction effects. RESULTS: Of the 49 959 infants in the analysis, 818 had a false-positive NBS result. We noted a significant interaction between gestational age and NBS results. We found that preterm, but not term, infants with false-positive results had more acute outpatient visits than their counterparts with normal NBS results. We found no difference in adjusted rates of other visit types (emergency department, inpatient, outpatient well) between infants with false-positive and normal NBS results, regardless of gestational age. CONCLUSIONS: Increased rates of acute outpatient visits among preterm infants with false-positive NBS screening results may be attributable to underlying chronic illness or parental anxiety. The absence of increased health care utilization among term infants may be unique to this Medicaid population or a subgroup phenomenon that was not detectable in this analysis.

Measuring Family HRQoL Spillover Effects Using Direct Health Utility Assessment

Background. Applications of cost-effectiveness analysis do not typically incorporate effects on caregiver quality of life despite increasing evidence that these effects are measurable. Methods. Using a national sample of US adults, we conducted 2 cross-sectional surveys during December 2011 and January 2012. One version asked respondents to value their own experience as the family member of a person with a chronic illness (experienced sample), and the other version asked respondents to value hypothetical scenarios describing the experience of having a family member with a chronic illness (community sample). Conditions included Alzheimer’s disease/dementia, arthritis, cancer, and depression. Using standard gamble questions, respondents were asked to value the spillover effects of a family member’s illness. We used regression analysis to evaluate the disutility (loss in health-related quality of life) of having a family member with a chronic illness by condition and relationship type, controlling for the respondent’s own conditions and sociodemographic characteristics. Results. For the experienced sample (n = 1389), regression analyses suggested that greater spillover was associated with certain conditions (arthritis, depression) compared with other conditions (Alzheimer’s disease, cancer). For the community sample (n = 1205), regression analyses indicated that lower spillover was associated with condition (cancer) but not the type of relationship with the ill family member (parent, child, spouse). Conclusions. The effects of illness extend beyond the individual patient to include effects on caregivers of patients, parents of ill children, spouses, and other close family and household members. Cost-effectiveness analyses should consider the inclusion of health-related quality of life spillover effects in addition to caregiving time costs incurred by family members of ill individuals.

Age and Sex Differences in Hospitalizations Associated with Diabetes

AIM To evaluate national trends in hospitalizations and hospital charges associated with diabetes over a recent 14-year period. METHODS We evaluated hospital discharges with a primary or secondary diagnosis of diabetes (250.xx)in the Nationwide Inpatient Sample (1993-2006). Outcomes included population-adjusted estimates of hospital discharges and hospital charges (2006

Inpatient Postpartum Long-Acting Reversible Contraception and Sterilization in the United States, 2008-2013

U.S.). RESULTS Overall, discharges associated with diabetes increased 65.3% (1,384/100,000 in 1993, 2,288/100,000 in 2006) over the 14-year period (p < 0.001 test for trend). The largest increase in hospitalizations occurred among adults 30-39 years of age, representing a 102% increase. Among young adults, increases among women were ∼1.3 times greater compared with men, for the 20-29 year (63% vs. 46%) and 30-39 year (118% vs. 85%) age groups, even after excluding pregnancy-related hospitalizations. Overall, women had higher rates of hospitalizations associated with diabetes compared with men, but there was evidence of an age by sex interaction, with higher rates of hospitalizations among women in the younger age groups and among men in the older age groups. Annual inflation-adjusted total charges for hospitalizations with diabetes increased 220% over the period. CONCLUSIONS Large increases in diabetes hospitalizations occurring among adults aged 30-39 years and young women signal a shift in the hospital burden of diabetes.

Changes in hospitals' credentialing requirements for board certification from 2005 to 2010

OBJECTIVE To measure rates of long-acting reversible contraception (LARC), including intrauterine devices and contraceptive implants, and tubal sterilization during delivery hospitalizations and correlates of their use. METHODS This retrospective cohort study used the 2008-2013 National Inpatient Sample, a publicly available all-payer database. We identified delivery hospitalizations with the International Classification of Diseases, 9th Revision, Clinical Modification codes for intrauterine device insertion, contraceptive implant insertion, and tubal sterilization. We used weighted multivariable logistic regression to examine associations between predictors (age, delivery mode, medical comorbidity, payer, hospital type, geographic region, and year) and likelihood of LARC and sterilization and to compare characteristics of LARC and sterilization users. RESULTS Our sample included 4,691,683 discharges, representing 22,667,204 delivery hospitalizations. Long-acting reversible contraception insertion increased from 1.86 per 10,000 deliveries (2008-2009) to 13.5 per 10,000 deliveries (2012-2013; P<.001); tubal sterilization remained stable (711-683 per 10,000 deliveries; P=.24). In multivariable analysis adjusting for all predictors, compared with neither LARC nor sterilization, LARC use was highest among women with medical comorbidities (count per 10,000 deliveries: 15.04, standard error 2.11, adjusted odds ratio [OR] 1.92, 95% confidence interval [CI] 1.72-2.13), nonprivate payer (13.50, standard error 2.14, adjusted OR 5.23, 95% CI 3.82-7.16), and at urban teaching hospitals (14.92, standard error 2.25, adjusted OR 20.85, 95% CI 12.73-34.15). Sterilization was least likely among women aged 24 years or younger (251.04, standard error 4.88, adjusted OR 0.12 95% CI 0.12-0.13, compared with 35 years or older) and most likely with cesarean delivery (1,568.74, standard error 20.81, adjusted OR 6.25, 95% CI 5.88-6.63). Comparing only LARC and sterilization users, LARC users tended to have nonprivate insurance (84.95% compared with 57.17%, adjusted OR 1.90, 95% CI 1.38-2.63) and deliver at urban teaching hospitals (94.65% compared with 45.47%, adjusted OR 38.39, 23.52-62.64) in later study years (2012-2013; 55.72% compared with 32.18%, adjusted OR 8.26, 95% CI 4.42-15.44, compared with 2008-2009). CONCLUSION Long-acting reversible contraception insertion increased from 1.86 to 13.5 per 10,000 deliveries but remained less than 2% of the sterilization rate. Inpatient postpartum LARC insertion is more likely among sicker, poorer women delivering at urban teaching hospitals.

Longitudinal influences of friends and parents upon unprotected vaginal intercourse in adolescents

OBJECTIVE In 2005, we conducted a study of the prevalence of board certification requirements for hospital privileging and found that one-third of hospitals did not require pediatricians to be board certified. In 2010, the American Board of Pediatrics implemented the Maintenance of Certification (MOC) program. To examine changes in the policies of hospitals regarding requirements for board certification, we surveyed privileging personnel at hospitals across the country. STUDY DESIGN Telephone survey between April 2010 and June 2010 of privileging personnel at a random sample of 220 hospitals. RESULTS Of the 220 hospitals, 23 were ineligible because they had no pediatricians on staff, and 26 hospitals refused to participate. The remaining 154 hospitals completed the survey, resulting in a 78% participation rate. Compared with our findings in 2005, in 2010 a greater proportion of hospitals now require board certification for general pediatricians (80% vs 67%, P = 0.141) and pediatric subspecialists (86% vs 71%, P = 0.048). Among these hospitals, a larger proportion (24% vs 4%) now requires board certification for all pediatricians at the point of initial privileging. However, a greater proportion of hospitals reported that they make exceptions to their board certification policies (99% vs 41%). CONCLUSION In the 5 years since our previous study, a larger proportion of hospitals now require pediatricians to be board certified, although the proportion of hospitals that make exceptions to this policy has increased twofold. Hospitals appear to be incorporating the MOC program into their privileging policies.

Change in settings for early-season influenza vaccination among US adults, 2012 to 2013

BACKGROUND Both friends and parents may influence occurrence of adolescent sexual intercourse, but these influences have not been studied together and prospectively. STUDY DESIGN We conducted a longitudinal analysis of a nationally representative sample of adolescents aged 15-18 years (n=6649), the National Longitudinal Study of Adolescent Health (Add Health). Baseline in-home and school interviews were conducted during 1995 and follow-up interviews in 1996. The main outcome measure was self-reported unprotected vaginal intercourse. RESULTS In models which adjusted for age, race, parental attitudes towards contraception and pregnancy, and adolescent sexual intercourse practices at baseline, having a friend who engaged in sexual intercourse at baseline, either unprotected (OR 2.2, 95% CI 1.6-3.2) or protected (OR 1.8, 95% CI 1.4-2.4), increased the odds of unprotected intercourse vs. never intercourse in the adolescent at follow-up (p<.001). A distant relationship with the father (OR 2.4, 95% CI 1.3-4.3) vs. a close relationship at baseline also increased the odds of unprotected intercourse at follow-up compared to never intercourse (p=.028). Parental attitudes were not associated with the outcome after consideration of the adolescents attitudes and baseline sexual practices. CONCLUSIONS Having a friend who engages in sexual intercourse, unprotected or protected, increases the risk of unprotected intercourse. Parental attitudes are less influential after consideration of adolescent baseline attitudes and sexual practices, suggesting that parental influences are strongest before 15 years of age. Our results suggest that early intervention among both parents and adolescents may decrease the risk of unprotected intercourse.

An Assessment of Public Preferences for Newborn Screening Using Best–Worst Scaling

Vaccination in non-medical settings is recommended as a strategy to increase access to seasonal influenza vaccine. To evaluate change in early-season influenza vaccination setting, we analyzed data from the National Internet Flu Survey. Bivariate comparison of respondent characteristics by location of vaccination was assessed using chi-square tests. Multinomial logistic regression was performed to compare the predicted probability of being vaccinated in medical, retail, and mobile settings in 2012 vs 2013. In both 2012 and 2013, vaccination in medical settings was more likely among elderly adults, those with chronic conditions, and adults with a high school education or less. Adults 18–64 without a chronic condition had a lower probability of vaccination in the medical setting, and higher probability of vaccination in a retail or mobile setting, in 2013 compared to 2012. Adults 18–64 with a chronic condition had no change in their location of flu vaccination. Elderly adults had a lower probability of vaccination in the medical setting, and higher probability of vaccination in a retail setting, in 2013 compared to 2012. Non-medical settings continue to play an increasing role in influenza vaccination of adults, particularly for adults without a chronic condition and elderly adults. Retail and mobile settings should continue to be viewed as important mechanisms to ensure broad access to influenza vaccination.

Insurance Among Young Adults With Inflammatory Bowel Disease: Changes Under the Affordable Care Act Dependent Provision

Objective To identify and quantify public preferences for attributes of newborn screening conditions. Study design We conducted an online national survey of the public (n = 502) to evaluate preferences for attributes of candidate newborn screening conditions. Respondents were presented with hypothetical condition profiles that were defined using 10 attributes with 2‐6 levels per attribute. Participants indicated whether they would recommend screening for a condition and which condition attributes were most and least important when making this decision (best–worst scaling). Difference scores were calculated and stratified by condition recommendation (recommend or not recommend for screening). Regression analyses were used to evaluate the effect of attributes on choice to screen or not screen. Results The number of babies diagnosed was important to those who would recommend newborn screening for a profile, and age at which the treatment would start was important to those who would not recommend newborn screening. Cost was considered to be a key attribute, and treatment effectiveness and impact of making the diagnosis through newborn screening were of low importance for both groups. Conclusion Public preferences identified through survey methods that provide an adequate baseline understanding of newborn screening can be used to inform newborn screening decisions.

Communication From Primary Care Practices Regarding Adolescent Immunization

Background: A total of 20% to 30% of patients with inflammatory bowel disease (IBD) present before age 18 years, eventually requiring transfer to adult care. Vulnerability during transfer may be exacerbated by loss of insurance. A provision of the Affordable Care Act (ACA) allows young adults (YAs) to remain on parental private insurance through age 25 years. There has been a decrease in uninsured YAs since its implementation in 2010. Little is known about whether insurance coverage of YAs with IBD has been affected. Objective: The aim of the present study was to determine whether the proportion of uninsured YAs with IBD has changed following the implementation of extended dependent eligibility under the ACA. Methods: We conducted a cross-sectional analysis of hospitalized patients with IBD, identified in the Nationwide Inpatient Sample (NIS) using diagnostic codes, to estimate proportions of insurance coverage during the years 2006–2013. We compared 19 to 25 year olds to 2 to 18 and 26 to 35 year olds, unaffected by the provision, to account for underlying trends. Results: From 2006 to 2010, 19 to 25 year olds had the highest proportion of uninsured, peaking at 14.1% in 2010. In 2011, the proportion decreased to 10.1%, below the proportion of uninsured 26 to 35 year olds (13.1%), remaining in this range through 2013. Private coverage increased in 2011 for 19 to 25 year olds, remaining stable for 26 to 35 year olds. Discussion: Previous research cited 5% uninsured among all hospitalized patients with IBD. Our study indicates a higher proportion for YAs, decreasing after the ACA. Lack of insurance increases vulnerability during transfer but may be modifiable through policy change. Furthermore, research should analyze the effects of Medicaid expansion and health care exchanges.
