The Influence of Clinical, Treatment, and Healthcare System Characteristics on Psychiatric Readmission of Adolescents

This study examined predictors of readmission for a sample of 522 adolescents enrolled in Medicaid and admitted to three inpatient psychiatric hospitals in Maryland. Comprehensive data on clinical, treatment, and health care system characteristics were collected from archival sources (medical records, Medicaid claims, and the Area Resource File). Predictors of readmission were examined with bivariate (Kaplan Meier) and multivariate (Cox Regression) survival techniques. One-year readmission rates were 38% with the majority occurring within 3 months after discharge. Adolescent demographic (age and gender), clinical (severity of symptoms, comorbidity, suicidality) and family characteristics (level of family risk) were associated with readmission. However, treatment factors including type of aftercare, postdischarge living environment, medication noncompliance, and hospital provider were among the strongest predictors of readmission. Study findings underscore the importance of careful discharge planning and linkage to appropriate aftercare. The differing rates of readmission across hospitals also suggest that organizational level factors may play a vital role in determining treatment outcomes.

Suicide trends among elementary school-aged children in the United States From 1993 to 2012

IMPORTANCE Suicide is a leading cause of death among school-aged children younger than 12 years but little is known about the epidemiology of suicide in this age group. OBJECTIVE To describe trends in suicide among US children younger than 12 years by sociodemographic group and method of death. DESIGN, SETTING, AND PARTICIPANTS Period trend analysis of national mortality data on suicide in children aged 5 to 11 years in the United States from January 1, 1993, to December 31, 2012. Data were analyzed per 5-year periods, between 1993 to 1997 and 2008 to 2012. MAIN OUTCOMES AND MEASURES Number of suicide deaths and crude suicide rates. Period trends in rates of suicide were estimated using negative binomial regression incidence rate ratios (IRRs). RESULTS The overall suicide rate among children aged 5 to 11 years remained stable between 1993 to 1997 and 2008 to 2012 (from 1.18 to 1.09 per 1 million; IRR = 0.96; 95% CI, 0.90-1.03). However, the suicide rate increased significantly in black children (from 1.36 to 2.54 per 1 million; IRR = 1.27; 95% CI, 1.11-1.45) and decreased in white children (from 1.14 to 0.77 per 1 million; IRR = 0.86; 95% CI, 0.79-0.94). The overall firearm suicide rate (IRR = 0.69; 95% CI, 0.57-0.85) and firearm suicide rate among white boys (IRR = 0.72; 95% CI, 0.59-0.88) decreased significantly during the study. The rate of suicide by hanging/suffocation increased significantly in black boys (IRR = 1.35; 95% CI, 1.14-1.61), although the overall change in suicide rates by hanging/suffocation or other suicide methods did not change during the study. CONCLUSIONS AND RELEVANCE The stable overall suicide rate in school-aged children in the United States during 20 years of study obscured a significant increase in suicide incidence in black children and a significant decrease in suicide incidence among white children. Findings highlight a potential racial disparity that warrants attention. Further studies are needed to monitor these emerging trends and identify risk, protective, and precipitating factors relevant to suicide prevention efforts in children younger than 12 years.

Suicide in Elementary School-Aged Children and Early Adolescents

BACKGROUND AND OBJECTIVES: Suicide in elementary school–aged children is not well studied, despite a recent increase in the suicide rate among US black children. The objectives of this study were to describe characteristics and precipitating circumstances of suicide in elementary school–aged children relative to early adolescent decedents and identify potential within-group racial differences. METHODS: We analyzed National Violent Death Reporting System (NVDRS) surveillance data capturing suicide deaths from 2003 to 2012 for 17 US states. Participants included all suicide decedents aged 5 to 14 years (N = 693). Age group comparisons (5–11 years and 12–14 years) were conducted by using the χ2 test or Fisher’s exact test, as appropriate. RESULTS: Compared with early adolescents who died by suicide, children who died by suicide were more commonly male, black, died by hanging/strangulation/suffocation, and died at home. Children who died by suicide more often experienced relationship problems with family members/friends (60.3% vs 46.0%; P = .02) and less often experienced boyfriend/girlfriend problems (0% vs 16.0%; P < .001) or left a suicide note (7.7% vs 30.2%; P < .001). Among suicide decedents with known mental health problems (n = 210), childhood decedents more often experienced attention-deficit disorder with or without hyperactivity (59.3% vs 29.0%; P = .002) and less often experienced depression/dysthymia (33.3% vs 65.6%; P = .001) compared with early adolescent decedents. CONCLUSIONS: These findings raise questions about impulsive responding to psychosocial adversity in younger suicide decedents, and they suggest a need for both common and developmentally-specific suicide prevention strategies during the elementary school–aged and early adolescent years. Further research should investigate factors associated with the recent increase in suicide rates among black children.

Factors Associated with Antidepressant Adherence for Medicaid-Enrolled Children and Adolescents

Background: Antidepressants have been shown to be efficacious for the treatment of pediatric depression. However, many youths do not receive an adequate duration of treatment, and factors associated with nonadherence in this population remain poorly understood. Objective: To examine rates of antidepressant adherence for depressed youth and identify factors associated with adherence during the acute and continuation phases of treatment. Methods: A retrospective cohort analysis was conducted using claims data from a state Medicaid-enrolled population of 1650 youths (aged 5-17 years) with new episodes of depression between January 1, 2005, and December 30, 2007. These patients were treated with selective serotonin reuptake inhibitors or newer antidepressants and followed for 6 months from the first prescription fill date. Adherence measures were derived from the Health Plan Employer Data and Information Set (HEDIS) quality indicators on antidepressant management (3 months of continuous treatment for the acute phase and 6 months for the continuation phase) and assessed using the medication possession ratio. Multivariate logistic regression analyses evaluated the association between demographic, clinical, medication, and treatment factors, and adherence. Results: About half (49.5%) of the youths were adherent to antidepressant medication during the acute phase, and 42% of these were adherent during the continuation phase; 21% were adherent across both treatment phases. Optimal follow-up visits and adequate antidepressant dosing was associated with better adherence during both treatment phases, as was use of other psychotropic medications. Youths prescribed trazodone for sleep had higher adherence rates during the acute phase. Minority youths and adolescents had lower adherence rates during the acute phase. Youths in foster care had higher adherence rates during both treatment phases. Conclusions: Nonadherence with antidepressant medications is common among Medicaid-covered children and adolescents. Study findings underscore the need for clinicians to deliver guideline-concordant care, assess adherence, and develop interventions that improve adherence, particularly for vulnerable subgroups.

Psychotropic Medication Changes, Polypharmacy, and the Risk of Early Readmission in Suicidal Adolescent Inpatients

Background: Adolescents with acute suicidal ideation and attempts are frequently treated with psychotropic medications in psychiatric hospitals. However, little is known about whether pharmacologic interventions used to stabilize suicidal adolescents within inpatient settings are effective in reducing early readmission. Objective: To examine whether psychotropic medication changes and polypharmacy are associated with 30-day readmission rates for suicidal adolescents. Methods: We conducted a retrospective cohort study of 318 Medicaid-enrolled adolescents admitted for suicidal behaviors to 3 major inpatient psychiatric hospitals in Maryland. Comprehensive data on patient demographics, clinical factors, service history, and inpatient treatment practices were collected from hospital medical records. Medications prescribed prior to admission and during the hospital stay were matched and compared with regard to drug, dosage, and frequency of administration to identify the different types of medication changes. Multivariate Cox proportional hazard analysis was used to examine the association of medication changes and polypharmacy with readmission. Results: At least one medication change was made in 78% of suicidal adolescent inpatients, typically the addition of an antidepressant, mood stabilizer, or antipsychotic. At discharge, nearly one quarter (23%) of youths were prescribed 3 or more medications from different drug classes. Controlling for demographic and clinical factors, the addition of an antidepressant was associated with an 85% lower risk of readmission (HR 0.15; 95% CI 0.03 to 0.68). However, the use of 3 or more medications from different drug classes was associated with a 2.6 times higher risk of readmission (95% CI 1.03 to 6.52). Conclusions: In this sample of suicidal adolescents, antidepressant treatment was associated with a lower risk of readmission and polypharmacy was associated with a higher risk of readmission. Study findings highlight the need for quality improvement efforts that optimize pharmacologic treatment and physician decision making.

Trends in Psychotropic Polypharmacy Among Youths Enrolled in Ohio Medicaid, 2002–2008

OBJECTIVE This study examined polypharmacy patterns and rates over time among Medicaid-enrolled youths by comparing three enrollment groups (youths in foster care, with a disability, or from a family with low income). METHODS Serial cross-sectional trend analyses of Medicaid claims data were conducted for youths age 17 and younger who were continuously enrolled in Ohio Medicaid for a one-year period and prescribed one or more psychotropic medications during fiscal years 2002 (N=26,252) through 2008 (N=50,311). Outcome measures were any polypharmacy (three or more psychotropic medications from any drug class) and multiclass polypharmacy (three or more psychotropic medications from different drug classes). RESULTS Both types of polypharmacy increased across all three eligibility groups. Any polypharmacy increased from 8.8% to 11.5% for low-income youths (adjusted odds ratio [AOR]=1.12, 99% confidence interval [CI]=1.10-1.13), from 18.0% to 24.9% for youths with a disability (AOR=1.11, CI=1.09-1.13), and from 19.8% to 27.3% for youths in foster care (AOR=1.09, CI=1.07-1.11). Combinations associated with positive increases were two or more antipsychotics, two or more stimulants, and antipsychotics with stimulants. CONCLUSIONS Polypharmacy increased across all enrollment groups, with the highest absolute rates for youths in foster care. Both the overall prevalence and increases in prescriptions for drug combinations with limited evidence of safety and efficacy, such as the prescription of two or more antipsychotics, underscore the need for targeted quality improvement efforts. System oversight and monitoring of psychotropic medication use appears to be warranted, especially for higher-risk groups, such as youths in foster care and those from low-income households who were prescribed multiple antipsychotics.

Prioritizing Research to Reduce Youth Suicide and Suicidal Behavior

The goal of the National Action Alliance for Suicide Prevention is to reduce suicide and suicide attempts in the U.S. by 40% in the next decade. In this paper, a public health approach is applied to suicide prevention to illustrate how reductions in youth suicide and suicidal behavior might be achieved by prioritizing research in two areas: (1) increasing access to primary care-based behavioral health interventions for depressed youth and (2) improving continuity of care for youth who present to emergency departments after a suicide attempt. Finally, some scientific, clinical, and methodologic breakthroughs needed to achieve rapid, substantial, and sustained reductions in youth suicide and suicidal behavior are discussed.

Individual and Contextual-Level Factors Associated with Continuity of Care for Adults with Schizophrenia

This retrospective cohort study examined rates of conformance to continuity of care treatment guidelines and factors associated with conformance for persons with schizophrenia. Subjects were 8,621 adult Ohio Medicaid recipients, aged 18–64, treated for schizophrenia in 2004. Information on individual-level (demographic and clinical characteristics) and contextual-level variables (county socio-demographic, economic, and health care resources) were abstracted from Medicaid claim files and the Area Resource File. Outcome measures captured four dimensions of continuity of care: (1) regularity of care; (2) transitions; (3) care coordination, and (4) treatment engagement. Multilevel modeling was used to assess the association between individual and contextual-level variables and the four continuity of care measures. The results indicated that conformance rates for continuity of care for adults with schizophrenia are below recommended guidelines and that variations in continuity of care are associated with both individual and contextual-level factors. Efforts to improve continuity of care should target high risk patient groups (racial/ethnic minorities, the dually diagnosed, and younger adults with early onset psychosis), as well as community-level risk factors (provider supply and geographic barriers of rural counties) that impede access to care.

Access to Mental Health Services: Implementing an Integrated Solution

The Surgeon General’s report 2 on mental health called national attention to the public health relevance of pediatric mental disorders, citing encouraging news of an increasing number of evidence-based treatments, as well as the discouraging news that most youth struggling with mental disorders receive no mental health services and that even when services are accessed, they are often inadequate in quality and/or quantity. More than a decade later, still less than half of young people with a mental disorder obtain treatment. 3 Given that mental health and substance use disorders are risk factors for several leading and potentially remediable causes of death, such as accidents, violence, and suicide, this disturbing reality likely has serious consequences for morbidity and mortality in the pediatric- and transitional-aged population. For example, a growing body of evidence indicates that improving access to effective mental health care can reduce suicide risk in young people. 4

Benzodiazepine use and risk of mortality among patients with schizophrenia: a retrospective longitudinal study.

OBJECTIVE This study examined the association between benzodiazepine use alone or in combination with antipsychotics and risk of mortality in patients with schizophrenia. METHODS A retrospective longitudinal analysis was performed using Medicaid claims data merged with death certificate data for 18,953 patients (aged 18-58 years) with ICD-9-diagnosed schizophrenia followed from July 1, 2006, to December 31, 2013. Cox proportional hazard analyses were used to estimate the risk of all-cause mortality associated with benzodiazepine use; adjustment was made for a wide array of fixed and time-varying confounders, including demographics, psychiatric and medical comorbidities, and other psychotropic medications. RESULTS Of the 18,953 patients diagnosed with schizophrenia, 13,741 (72.5%) were not prescribed a benzodiazepine, 3,476 (18.3%) were prescribed benzodiazepines in the absence of antipsychotic medication, and 1,736 (9.2%) were prescribed benzodiazepines in combination with antipsychotics. Controlling for a wide array of demographic and clinical variables, the hazard of mortality was 208% higher for patients prescribed benzodiazepines without an antipsychotic (HR = 3.08; 95% CI, 2.63-3.61; P < .001) and 48% higher for patients prescribed benzodiazepines in combination with antipsychotics (HR = 1.48; 95% CI, 1.15-1.91; P = .002). Benzodiazepine-prescribed patients were at greater risk of death by suicide and accidental poisoning as well as from natural causes. CONCLUSIONS Benzodiazepine use is associated with increased mortality risk in patients with schizophrenia after adjusting for a wide range of potential confounders. Given unproven efficacy, physicians should exercise caution in prescribing benzodiazepines to schizophrenic patients.
