RESUMO
BACKGROUND: Hepatitis C virus (HCV) prevalence doubled among pregnant women from 2009 to 2014, reaching 3.4 per 1000 births nationwide. Infants exposed to HCV may acquire HCV by vertical transmission. National guidelines recommend that infants exposed to HCV be tested; however, it is unclear if these recommendations are being followed. Our objectives were to determine if infants exposed to HCV were tested and to determine hospital- and patient-level factors associated with differences in testing. METHODS: In this retrospective cohort study of infants exposed to HCV who were enrolled in the Tennessee Medicaid program, we used vital statistics-linked administrative data for infants born between January 1, 2005, and December 31, 2014. Infants were followed until 2 years old. Multilevel logistic regression was used to assess the association of HCV testing and hospital- and patient-level characteristics. RESULTS: Only 23% of 4072 infants exposed to HCV were tested. Infants whose mothers were white versus African American (96.6% vs 3.1%; P <.001), used tobacco (78% vs 70%; P <.001), and had HIV (1.3% vs 0.4%; P = .002) were more likely to be tested. Infants exposed to HCV who had a higher median of well-child visits (7 vs 6; P <.001) were more likely to be tested. After accounting for maternal and infant characteristics and health care use patterns, African American infants were less likely to undergo general testing (adjusted odds ratio 0.32; 95% confidence interval, 0.13-0.78). CONCLUSIONS: Testing occurred in <1 in 4 infants exposed to HCV and less frequently among African American infants. Public health systems need to be bolstered to ensure that infants exposed to HCV are tested for seroconversion.

OBJECTIVES: Neonatal abstinence syndrome (NAS) is a postnatal withdrawal syndrome experienced by some infants with opioid exposure. Hospital administrative data are commonly used for research and surveillance but have not been validated for NAS. Our objectives for this study were to validate the diagnostic codes for NAS and to develop an algorithm to optimize identification. METHODS: Tennessee Medicaid claims from 2009 to 2011 (primary sample) and 2016 (secondary sample; post-International Classification of Diseases, 10th Revision, Clinical Modification [ICD-10-CM]) were obtained. Cases of NAS were identified by using International Classification of Diseases, Ninth Revision, Clinical Modification code (2009-2011) 779.5 and ICD-10-CM code (2016) P96.1. Medical record review cases were then conducted by 2 physicians using a standardized algorithm, and positive predictive value (PPV) was calculated. Algorithms were developed for optimizing the identification of NAS in administrative data. RESULTS: In our primary sample of 112 029 mother-infant dyads, 950 potential NAS cases were identified from Medicaid claims data and reviewed. Among reviewed records, 863 were confirmed as having NAS (including 628 [66.1%] cases identified as NAS requiring pharmacotherapy, 224 [23.5%] as NAS not requiring pharmacotherapy, and 11 [1.2%] as iatrogenic NAS), and 87 (9.2%) did not meet clinical criteria for NAS. The PPV of the International Classification of Diseases, Ninth Revision, Clinical Modification code for NAS in clinically confirmed NAS was 91% (95% confidence interval: 88.8%-92.5%). Similarly, the PPV for the ICD-10-CM code in the secondary sample was 98.2% (95% confidence interval: 95.4%-99.2%). Algorithms using elements from the Medicaid claims and from length of stay improved PPV. CONCLUSIONS: In a large population-based cohort of Medicaid participants, hospital administrative data had a high PPV in identifying cases of clinically diagnosed NAS.

BACKGROUND AND OBJECTIVES: Little is known about opioid prescribing for children without severe conditions. We studied the prevalence of and indications for outpatient opioid prescriptions and the incidence of opioid-related adverse events in this population. METHODS: This retrospective cohort study between 1999 and 2014 included Tennessee Medicaid children and adolescents aged 2 to 17 without major chronic diseases, prolonged hospitalization, institutional residence, or evidence of a substance use disorder. We estimated the annual prevalence of outpatient opioid prescriptions and incidence of opioid-related adverse events, defined as an emergency department visit, hospitalization, or death related to an opioid adverse effect. RESULTS: There were 1 362 503 outpatient opioid prescriptions; the annual mean prevalence of opioid prescriptions was 15.0%. The most common opioid indications were dental procedures (31.1% prescriptions), outpatient procedure and/or surgery (25.1%), trauma (18.1%), and infections (16.5%). There were 437 cases of opioid-related adverse events confirmed by medical record review; 88.6% were related to the child's prescription and 71.2% had no recorded evidence of deviation from the prescribed regimen. The cumulative incidence of opioid-related adverse events was 38.3 of 100 000 prescriptions. Adverse events increased with age (incidence rate ratio = 2.22; 95% confidence interval, 1.67-2.96; 12-17 vs 2-5 years of age) and higher opioid doses (incidence rate ratio = 1.86 [1.45-2.39]; upper versus lower dose tertiles). CONCLUSIONS: Children without severe conditions enrolled in Tennessee Medicaid frequently filled outpatient opioid prescriptions for acute, self-limited conditions. One of every 2611 study opioid prescriptions was followed by an opioid-related adverse event (71.2% of which were related to therapeutic use of the prescribed opioid).

BACKGROUND: The use of opioids is increasing in children; therefore, opioid toxicity could be a public health problem in this vulnerable population. However, we are not aware of a published algorithm to identify cases of opioid toxicity in children using administrative databases. We sought to develop an algorithm to identify them. After review of literature and de-identified computer profiles, a broad set of ICD-9 CM codes consistent with serious opioid toxicity was selected. Based on these codes, we identified 195 potential cases of opioid toxicity in children enrolled in Tennessee Medicaid. Medical records were independently reviewed by two physicians; episodes considered equivocal were reviewed by an adjudication committee. Cases were adjudicated as Group 1 (definite/probable), Group 2 (possible), or Group 3 (excluded). RESULTS: Of the 195 potential cases, 168 (86.2%) had complete records for review and 85 were confirmed cases. The overall positive predictive value (PPV) for all codes was 50.6%. The PPV for codes indicating: unintentional opioid overdose (25/31) was 80.7%; intentional opioid overdose (15/30) was 50.0%, adverse events (33/58) was 56.9%, the presence of signs or symptoms compatible with opioid toxicity (12/47) was 25.5%, and no cases were confirmed in records from the two deaths. Of the confirmed cases, 65.8% were related to therapeutic opioid use. CONCLUSION: For studies utilizing administrative claims to quantify incidence of opioid toxicity in children, our findings suggest that use of a broad set of screening codes coupled with medical record review is important to increase the completeness of case ascertainment.

OBJECTIVE: Guidelines and quality of care measures for the evaluation of adolescent suicidal behavior recommend prompt mental health evaluation, hospitalization of high-risk youth, and specific follow-up plans-all of which may be influenced by sociodemographic factors. The aim of this study was to identify sociodemographic characteristics associated with variations in the evaluation of youth with suicidal behavior. METHODS: We conducted a large cohort study of youth, aged 7 to 18, enrolled in Tennessee Medicaid from 1995 to 2006, who filled prescriptions for antidepressants and who presented for evaluation of injuries that were determined to be suicidal on the basis of external cause-of-injury codes (E codes) and ICD-9-CM codes and review of individual medical records. Chi-square tests and logistic regression were performed to assess the relationship between sociodemographic characteristics and documentation of mental health evaluation, hospitalization, and discharge instructions. RESULTS: Of 929 episodes of suicidal behavior evaluated in an acute setting, rural-residing youth were less likely to be admitted to a psychiatric hospital (adjusted odds ratio [AOR] 0.72; 95% confidence interval [CI] 0.55-0.95) and more likely to be medically hospitalized only (AOR 1.92; 95% CI 1.39-2.65). Female subjects were less likely to be admitted to a psychiatric hospital (AOR 0.55; 95% CI 0.41-0.74) and more likely to be discharged home (AOR 1.44; 95% CI 1.01-2.04). Only 40% of those discharged to home had documentation of discharge instructions with both follow-up provider and date. CONCLUSIONS: In this statewide cohort of youth with suicidal behavior, there were significant differences in disposition associated with sociodemographic characteristics.

PURPOSE: To assess the safety of psychotropic medication use in children and adolescents, it is critical to be able to identify suicidal behaviors from medical claims data and distinguish them from other injuries. The purpose of this study was to develop an algorithm using administrative claims data to identify medically treated suicidal behavior in a cohort of children and adolescents. METHODS: The cohort included 80,183 youth (6-18 years) enrolled in Tennessee's Medicaid program from 1995-2006 who were prescribed antidepressants. Potential episodes of suicidal behavior were identified using external cause-of-injury codes (E-codes) and ICD-9-CM codes corresponding to the potential mechanisms of or injuries resulting from suicidal behavior. For each identified episode, medical records were reviewed to determine if the injury was self-inflicted and if intent to die was explicitly stated or could be inferred. RESULTS: Medical records were reviewed for 2676 episodes of potential self-harm identified through claims data. Among 1162 episodes that were classified as suicidal behavior, 1117 (96%) had a claim for suicide and self-inflicted injury, poisoning by drugs, or both. The positive predictive value of code groups to predict suicidal behavior ranged from 0-88% and improved when there was a concomitant hospitalization but with the limitation of excluding some episodes of confirmed suicidal behavior. CONCLUSIONS: Nearly all episodes of confirmed suicidal behavior in this cohort of youth included an ICD-9-CM code for suicide or poisoning by drugs. An algorithm combining these ICD-9-CM codes and hospital stay greatly improved the positive predictive value for identifying medically treated suicidal behavior.

OBJECTIVE: The purpose of this work was to estimate the incidence of medically treated thyroid disease in children with Down syndrome enrolled in Tennessee Medicaid (TennCare) during 1995-2005 and to determine whether rates increased after rerelease of American Academy of Pediatrics guidelines in 2001. PATIENTS AND METHODS: We conducted a population-based retrospective cohort study in which we identified children with Down syndrome by using TennCare files and birth certificates. We included 1- to 18-year-olds who were continuously enrolled in TennCare and did not fill a prescription for thyroid medication during a 90-day prestudy period. The rate of medically treated thyroid disease (prescription filled for thyroid medication) was the main outcome. We used Poisson regression to estimate rates of medically treated thyroid disease according to study year, age, gender, race, region of residence, and payer type. RESULTS: During the 11-year study period, 1257 children with Down syndrome (28% black, 72% white) met inclusion criteria. Overall, 10.8% filled a new prescription for thyroid medication. Rates of medically treated thyroid disease per 1000 child-years were 13.25 (1995-1997), 13.34 (1998-1999), 13.62 (2000-2001), 22.37 (2002-2003), and 22.51 (2004-2005). After adjusting for child age and race, there was an increased rate of medically treated thyroid disease in 2002-2003 and 2004-2005 compared with 1995-1997. In a comparison cohort of children without Down syndrome, there was a smaller increase in the rate of medically treated thyroid disease when comparing 2002-2003 and 2004-2005 with 1995-1997. CONCLUSIONS: Over the 11-year period, 10.8% of children with Down syndrome filled a new prescription for a thyroid medication. A 73% increase in the incidence of medically treated thyroid disease occurred after rerelease of American Academy of Pediatrics guidelines, which may have influenced screening.

OBJECTIVE: To test the hypothesis that children enrolled in Medicaid managed care health plans that provide asthma-specific communication to providers would be more likely to have adequate asthma medication filling. STUDY DESIGN: We conducted a historical cohort study of 4498 children (2-17 years old) with moderate-severe asthma in Washington State and Tennessee Medicaid managed care programs from 2000 to 2002. Interviews with health plans were conducted to identify communication strategies health plans used to improve asthma care by providers in the plan. The main outcome measure was guideline-recommended filling of asthma preventer medications. RESULTS: Children in plans that provided specific feedback to providers about asthma quality and notified providers when children had an asthma-related event had the highest mean days plus or minus SE of filling in the 365-day follow-up period (164.6 +/- 13 days) compared with children in plans with neither (135.3 +/- 10.8 days; P < .05). In children with the greatest asthma severity, enrollment in a plan with both features was associated with 27.1 additional days of filling (95% CI, 0.7-53.4 days) during the follow-up period. CONCLUSION: Health plan communication to providers was associated with increased preventer filling in children with moderate-severe asthma in 2 state Medicaid programs.

OBJECTIVE: To evaluate the effect of UK and US warnings placed in response to reports of suicidal thinking in pediatric patients receiving selective serotonin reuptake inhibitor and selective norepinephrine reuptake inhibitor antidepressants on antidepressant prescribing for children and adolescents. DESIGN: Interrupted time-series analysis of antidepressant prescriptions. SETTING: Tennessee's Medicaid program, January 1, 2002, through September 30, 2005. PARTICIPANTS: A mean of 405,000 children and adolescents aged 2 to 17 years qualified each month. Main Exposure Piecewise linear regression models were used to estimate the cumulative effect of the warnings, which were considered the exposure of interest. MAIN OUTCOME MEASURES: Monthly proportions of study children and adolescents who were new users of antidepressants, had discontinuity in antidepressant use, or were users of other psychotropic drugs. RESULTS: During the 2 years preceding the UK warning, there was no trend in the monthly proportions of new antidepressant users, with 23 new users per 10 000 persons per month. This proportion subsequently decreased 33% (95% confidence interval, 23% to 41%; P < .001) by 21 months following the UK warning. The reduction was most pronounced for the nonfluoxetine selective serotonin reuptake inhibitors and selective norepinephrine reuptake inhibitors, where initiations decreased 54% (95% confidence interval, 46% to 62%; P < .001). In contrast, new users of fluoxetine increased 60% (95% confidence interval, 9% to 135%; P = .02). There was no increase in discontinuations of antidepressants, and there was no evidence of substitution of other psychotropic drugs. CONCLUSION: The regulatory warnings led to decreased use of antidepressants in children and adolescents, but the clinical and public health consequences of this change are unknown.
