A Critique on Psychiatric Inpatient Admissions for Suicidality in Youth.

ABSTRACT: For the last few decades, psychiatric inpatient admissions for the treatment of suicidality in US youth have been increasing. Nonetheless, since 2007, the national rate of completed suicides by youth has steadily and sizably increased. Therefore, a literature review was performed to evaluate the usefulness of the psychiatric inpatient admission of suicidal youths. The analysis concluded that suicidality is surprisingly common in youth, completed suicide is very uncommon in early adolescence, suicidal ideation is a major reason in early adolescence for inpatient admission, girls are admitted to psychiatric inpatient units three times more than boys even though boys complete suicide four times more than girls, inpatient stays average 6 days and are quite expensive, and repeat attempts after inpatient treatment are common. Thus, filling more beds for youth with suicidality lacks evidence of a public health, long-term benefit. Expanding the focus in psychiatry to population efforts including means reductions is recommended.

Hispanic Residential Isolation, ADHD Diagnosis and Stimulant Treatment among Medicaid-Insured Youth.

OBJECTIVE: This study aimed to evaluate a conceptual framework that assessed the effect of Hispanic residential isolation on Attention Deficit Hyperactivity Disorder (ADHD) health service utilization among 2.2 million publicly insured youth. DESIGN: Cross-sectional. SETTING: Medicaid administrative claims data for ambulatory care services from a US Pacific state linked with US census data. PARTICIPANTS: Youth, aged 2-17 years, continuously enrolled in 2009. MAIN OUTCOME MEASURES: The percent annual prevalence and odds of ADHD diagnosis and stimulant use according to two measures of racial/ethnic residential isolation: 1) the county-level Hispanic isolation index (HI) defined as the population density of Hispanic residents in relation to other racial/ethnic groups in a county (<.5; .5-.64; ≥.65); and 2) the proportion of Hispanic residents in a ZIP code tabulation area (<25%; 25%-50%; >50%). RESULTS: Among the 47,364 youth with a clinician-reported ADHD diagnosis, 60% received a stimulant treatment (N = 28,334). As the county level HI increased, Hispanic residents of ethnically isolated locales were significantly less likely to receive an ADHD diagnosis (adjusted odds ratio [AOR]=.92 [95% CI=.88-.96]) and stimulant use (AOR=.61 [95% CI=.59-.64]) compared with Hispanic youth in less isolated areas. At the ZIP code level, a similar pattern of reduced ADHD diagnosis (AOR=.81 [95% CI=.77-.86]) and reduced stimulant use (AOR=.65 [95% CI=.61-.69]) was observed as Hispanic residential isolation increased from the least isolated to the most isolated ZIP code areas. CONCLUSIONS: These findings highlight the opportunity for Big Data to advance mental health research on strategies to reduce racial/ethnic health disparities, particularly for poor and vulnerable youth. Further exploration of racial/ethnic residential isolation in other large data sources is needed to guide future policy development and to target culturally sensitive interventions.

Raising the Minimum Effective Dose of Serotonin Reuptake Inhibitor Antidepressants: Adverse Drug Events.

This review focuses on the dose-response of serotonin reuptake inhibitor (SRI) antidepressants for efficacy and for adverse drug events (ADEs). Dose-response is identified by placebo-controlled, double-blind, fixed-dose clinical trials comparing various doses for efficacy and for ADEs. Reports from the great majority of clinical trials have consistently found that the minimum SRI effective dose is usually optimal for efficacy in the treatment of depression disorders, even though most American medical practitioners raise the dose when early antidepressant treatment results are negative or partial. To better understand this issue, the medical literature was comprehensively reviewed to ascertain the degree to which SRI medications resulted in a flat dose response for efficacy and then to identify specific ADEs that are dose-dependent. Strong evidence from fixed-dose trial data for the efficacy of nonascendant, minimum effective doses of SRIs was found for the treatment of both major depression and anxiety disorders. Particularly important was the finding that most SRI ADEs have an ascending dose-response curve. These ADEs include sexual dysfunction, hypertension, cardiac conduction risks, hyperglycemia, decreased bone density, sweating, withdrawal symptoms, and agitation. Thus, routinely raising the SRI dose above the minimum effective dose for efficacy can be counter-productive.

Antipsychotic prescribing for behavioral disorders in US youth: physician specialty, insurance coverage, and complex regimens.

PURPOSE: To assess antipsychotic prescribing patterns according to insurance coverage type and physician specialty in the outpatient treatment of behavioral disorders (BD) in US youth. METHODS: We used 2003-2010 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey data to compare antipsychotic prescribing in the outpatient treatment of BD in youth (6-19 years) according to insurance coverage (public vs. private) and physician specialty (psychiatrist vs. non-psychiatrist) using population-weighted Chi-square and multivariable analyses. Also, we examined co-prescribing of antipsychotics with other psychotropic medication classes. Subgroup analyses were conducted in BD visits with no other clinician-reported psychiatric diagnosis (non-comorbid BD visits). RESULTS: A large majority (71.0%) of BD visits were provided by non-psychiatrists. However, psychiatrists prescribed antipsychotics far more frequently than non-psychiatrists (24.2% vs. 4.6%; adjusted odds ratio (AOR) = 5.1 [95% confidence interval (CI), 2.8-9.2]) in total BD visits as well as in non-comorbid BD visits (18.6% vs. 3.6%; AOR = 5.8 [95% CI, 3.2-10.5]). Antipsychotic prescribing was nearly two-fold greater in visits by publicly insured 6-12 year olds (11.3% vs. 5.8%; AOR = 1.9 [95% CI, 1.1-3.5]) and 13-19 year olds (16.2% vs. 8.9%; AOR = 2.0 [95% CI, 1.1-3.6]) compared with their privately insured counterparts. In more than one-third of antipsychotic-prescribed BD visits, antipsychotics were prescribed concomitantly with ≥2 psychotropic medication classes regardless of age group, insurance coverage, or even in the absence of psychiatric comorbidities. CONCLUSION: In outpatient visits by youth for BD, antipsychotics were primarily prescribed by psychiatrists, concomitantly, and for the publicly insured. These treatment patterns merit further investigation.

Number needed to harm: its limitations in psychotropic drug safety research.

Commonly used statistical measures to quantify the likelihood of an adverse drug event (ADE) from clinical trials include risk ratio; odds ratio; and number needed to harm (NNH), the reciprocal of absolute risk. This critical review focused on NNH, specifically on its limitations in controlled trials with psychotropic medication. Data for this evaluation were obtained primarily from articles in MEDLINE from 1988 to 2012. Limitations of NNH were found to include the following: a) arbitrary binary cutoffs for continuous measures, b) limited use of confidence intervals, c) limited adjustments for potential baseline confounders, d) limited adjustments for differences in dose and treatment duration, e) rare consideration of high attrition rates, f) variable use of the term harm, g) oversimplified single harm comparisons, h) frequent biased design and reporting, i) undue emphasis on less severe ADEs, j) application primarily to short-term clinical trials, and k) little or no generalizability in community practice. In sum, the NNH metric supplies very limited information on the risks of psychotropic medication. Postmarketing surveillance of community treatment populations using case-control methodology provides far more useful data on serious ADEs.

Lorazepam use during clinical trials of adults with bipolar mania episodes.

Background: Lorazepam has commonly been prescribed to reduce agitation during bipolar 1 mania trials. Its use has varied considerably by trial methodology and in clinical practice. Methods: The extent and amount of lorazepam treatment was recorded and analyzed from available brief, controlled trials of acute bipolar mania and in clinical reports in adults. Results: In 3-week, placebo-controlled clinical trials (n = 19), most manic subjects (79%) were treated with lorazepam to reduce agitation. This treatment was most prominent during the antimanic drug wash-out phase that preceded placebo-controlled trials. Doses of lorazepam administered during the first 7-10 days of the pre-trial and the early trial phases averaged 2.2 mg/day. These doses were one-third the lorazepam/clonazepam doses administered during placebo-controlled, non-washout trials. Far higher benzodiazepine doses for manic agitation were noted in emergency department reports. Intake enrollment was strikingly restricted only in placebo-controlled trials that used pretrial drug wash-out. Conclusions: Medication treatment conclusions from placebo-controlled, drug washout trials are not representative of clinical treatment for acute bipolar mania.

Age-grouped differences in bipolar mania.

OBJECTIVE: This review of published studies compares scores on individual items of mania rating scales that systematically recorded symptom severity in persons diagnosed with bipolar disorder to identify age-grouped differences. METHODS: An extensive literature search identified item scores from mania rating scales, with a particular emphasis on baseline Young Mania Rating Scale (YMRS) item scores in published double-blind, placebo-controlled studies of bipolar I manic disorder. These baseline YMRS item scores were assessed as a proportion of the total YMRS score and compared by age group. Additional YMRS item/total scores in subjects with bipolar spectrum disorders were added to expand the analysis. RESULTS: Preadolescents with bipolar disorder had significantly higher YMRS item scores than adolescents on aggression, irritability, and motor activity. Young Mania Rating Scale baseline item scores relative to the YMRS total score revealed that adolescents diagnosed with bipolar I mania scored comparatively higher than did adults on YMRS aggression and irritability items, whereas adults with bipolar I manic disorder scored comparatively higher on the grandiosity and sexual interest items. Age-grouped findings from subjects diagnosed with bipolar I, II, and Not Otherwise Specified (NOS) disorders yielded similar age-grouped results. CONCLUSION: In age-grouped YMRS item assessments of bipolar mania, anger dyscontrol was most prominent for youth, whereas disordered thought content was paramount for adults.

Psychotropic Polypharmacy in the US Pediatric Population: A Methodologic Critique and Commentary.

Background: Psychotropic concomitant medication use for the treatment of youth with emotional and behavioral disorders has grown significantly in the U.S. over the past 25 years. The use of pharmacy claims to analyze these trends requires the following: age of the selected population, overlapping days of use, and precision of the outcome itself. This review will also address the gaps in reporting of pediatric psychotropic polypharmacy. Methods: An electronic literature search was undertaken for the period 2000 through 2020 using keywords such as "pediatric," "concomitant," "polypharmacy," "multiple medications," and "concurrent psychotropic"; Relevant references in textbooks were also used. Only English language and U.S. studies were included, resulting in 35 inter-class studies. Results: Studies were organized into seven groups according to data sources and clinical topics: (1) population surveys; (2a) multi-state publicly insured populations; (2b) single/two state studies; (3) privately insured populations; (4) diagnosed populations; (5) foster care populations; (6) special settings. Across 20 years it is apparent that pediatric psychotropic polypharmacy affects substantially more children and adolescents today than had been the case. As many as 300,000 youth now receive 3 or more classes concomitantly. The duration of concomitant use is relatively long, e.g., 69-89% of annual medicated days. Finally, more adverse event reports were associated with 3-class compared with 2-class drug regimens. Discussion: Factors that contribute to the growth of pediatric psychotropic polypharmacy include: (1) predominance of the biological model in psychiatric practice; (2) invalid assumptions on efficacy of combinations, (3) limited professional awareness of metabolic and neurological adverse drug events, and (4) infrequent use of appropriate deprescribing. Conclusion: A review of publications documenting U.S. pediatric psychotropic polypharmacy written over the last 20 years supports the need to standardize the methodologies used. The design of population-based studies should maximize information on the number of youth receiving regimens of 3-, 4-, and 5 or more concomitant classes and the duration of such use. Next, far more post-marketing research is needed to address the effectiveness, safety and tolerability of complex drug regimens prescribed for youngsters.

Impact of the 2004 Food and Drug Administration pediatric suicidality warning on antidepressant and psychotherapy treatment for new-onset depression.

OBJECTIVE: To assess the national impact of the March 2004 Food and Drug Administration (FDA) antidepressant suicidality warning on the outpatient treatment of new-onset depression in youth. METHOD: A repeated measures, longitudinal design in a cohort of youth diagnosed with new-onset depression was used to assess pre- and post-FDA warning effects. US commercial insurance enrollees in the i3 INNOVUS database from January 2003 through December 2006 were examined. The study population included youth 2- to 17-years old with a new-onset depression diagnosis from July 2003 through June 2006 (N = 40,309). The main independent variables were the warning period (post- vs. pre-FDA warning) and age group (children vs. adolescents). The main outcome measures were youth with antidepressant dispensings and psychotherapy visits measured in 30-day intervals across 36 months following a new-onset diagnosis of any depressive disorder (N = 40,309) and specifically major depressive disorder (MDD) (N = 11,532). RESULTS: Compared to youth with a new-onset diagnosis of depression in the pre-FDA warning period, youth with new-onset diagnosis of depression during the postwarning period had (1) A significantly lower likelihood of antidepressant use: (odds ratio [OR] = 0.85 [0.81-0.89]); When youth with the diagnosis of depression were separated into those with MDD and those with less severe depression diagnoses, only the latter had a significant postwarning antidepressant decline. (2) A significant increase in the odds of a psychotherapy visit (children, OR = 1.31 [1.23-1.40]; adolescents OR = 1.19 [1.15-1.24]). CONCLUSIONS: The FDA suicidality warning was associated with an overall decrease in antidepressant treatment for youth with a clinician-reported diagnosis of depression, but not for those with MDD. Also, following the warning, psychotherapy without medication increased.

Mood swing and mood stabilizer: how specific are these terms?

BACKGROUND: In the DSM-IIIR in 1987, the category title for depressive and bipolar disorders was changed from affective disorders to mood disorders. Within a short period of time thereafter, mood swing and mood stabilizer became very commonly used terms in psychiatry with bipolar implications. METHODS: Terms and definitions in recent texts, articles, and dictionaries pertaining to mood fluctuations have been reviewed. RESULTS: The term mood was seldom part of psychiatric terminology until the late 1970s. Mood swing and mood stabilizer as used in the psychiatric literature are primarily nonspecific and often misleading concepts--particularly as a basis for treatment decisions. Affective fluctuations and shifts to irritability and/or anger in persons with personality and depressive disorders are being viewed by many in the mental health field as cyclically biphasic--between depressed to elated--which is clearly at variance with research findings. CONCLUSIONS: More data-based research on mood variations is needed to authoritatively remedy this situation.

Antidepressant Use in Medicaid-Insured Youth: Trends, Covariates, and Future Research Needs.

BACKGROUND: Detailed research on long-term antidepressant (AD) trends within a single large US Medicaid population of youth has not heretofore been reported. METHODS: Administrative claims data for eight annual timepoints across 28 years (1987-2014) were organized for youth (<20 years old) who were continuously enrolled during each study year in a mid-Atlantic state Medicaid program. Total annual AD prevalence and age-, gender-, race-, eligibility group-, and diagnosis-specific prevalence were formed from bivariate analyses; logistic regression assessed the change in use (2007-2014) adjusted for covariates. AD-polypharmacy data were assessed in 2014. RESULTS: The major findings are: 1) AD use in state Medicaid enrollees grew 14-fold between 1987 and 2014. Data from 2014 revealed significantly increased odds of youth with SSRI/SNRI dispensings compared to 2007 (AOR=1.15 95% CI 1.11-1.19), representing 78% of total AD users. 2) Recent AD increases were greatest for 15-19-year olds. 3) AD use in girls passed up AD use in boys for the first time in 2014. 4) In 2014, ADs for foster care (12.7%) were 6 times greater than for their income-eligible Medicaid-counterparts. 5) In 2014, a quarter of AD-medicated youth were diagnosed with a behavior disorder. 6) More than 40 percent of AD medicated youth had >=1 other concomitant psychotropic classes for 60 or more days. CONCLUSIONS: Second-generation antidepressant use in Medicaid-insured youth has increased despite growing questions that pediatric AD benefits may not outweigh harms. These patterns support the call for publicly funded, independent investigator-conducted post-marketing outcomes research.

Overprescribed Medications for US Adults: Four Major Examples.

To understand possible medication overprescribing, it would be important to know which classes are the most prescribed, for which indications, for what duration, and for which age groups. Among the 10 most frequently prescribed medication classes for US adults, four were evaluated for overprescribing, and systematically assessed in relation to their primary indication. The assessment included usage patterns, trends, age of recipients, treatment duration, and benefits versus adverse consequences. The findings in this selective review are supported by an extensive search of the medical literature. The four selected medication categories and their most common indication included opioids for chronic pain, proton pump inhibitors for indigestion, levothyroxine for subclinical hypothyroidism, and antidepressants for subsyndromal levels of depression. These medications, grouped by their most frequent indication along with polypharmacy, have experienced major prescription increases in recent years, particularly among older patients. Most concerning is that they have been frequently prescribed for extended periods, usually with inadequate evidence of benefit. High drug usage patterns can aid in quantifying overprescribing within polypharmacy by age group.

Short- and Long-Term Antidepressant Clinical Trials for Major Depressive Disorder in Youth: Findings and Concerns.

The diagnosis of major depressive disorder (MDD) in U.S. youth is increasing as is the rate of antidepressant medication (ADM) treatment for the disorder. Fluoxetine and escitalopram are FDA approved for the short term and maintenance treatment of MDD in youth. Placebo-controlled short-term ADM trials represent the basis for Food and Drug Administration (FDA) approval. Meta-analyses in 2007 and 2016 revealed that short-term ADM treatment of youth diagnosed with MDD resulted in no meaningful benefit for children and only marginal benefit for adolescents. Placebo substitution trials of ADM short-term responders represent the basis for FDA approval of ADM maintenance treatment. These ADM placebo substitution maintenance trials for youth with MDD are characterized by high dropout rates, a rapid withdrawal that often can follow the switch to placebo, and relapse rates that are not dissimilar from those in the natural course of the disorder. Without the evidence from problematic ADM placebo substitution trials, there is no acceptable support for the inclusion of ADM in maintenance treatment for MDD in youth.

Is ADHD Really Increasing in Youth?

OBJECTIVE: It would be useful to compare temporal changes in the diagnostic prevalence of ADHD obtained from identical population surveys with time-trend survey findings based on individual ADHD features. METHOD: Changes in the diagnostic prevalence of ADHD over time were recorded from parent reports and from physician office visit data. Associated features of ADHD were temporally recorded from standardized teacher, parent, and youth surveys. RESULTS: Time-trend diagnostic findings on ADHD prevalence based on 6 parent surveys and 12 outpatient physician office visit surveys revealed consistent rate increases. By contrast, 26 sets of standard ratings of the primary and associated features of ADHD assessed systematically by different teachers, parents, and students during different years indicated little change. CONCLUSION: Time-trend national surveys of ADHD in youth over the last two decades reveal consistent increases in its diagnostic prevalence, whereas time-trend findings for individual ADHD-related symptoms remained relatively stable.

The Impact of a State Medicaid Peer-Review Authorization Program on Pediatric Use of Antipsychotic Medications.

OBJECTIVE: This cross-sectional study assessed the impact of a peer-review program on the prevalence of pediatric antipsychotic use among Medicaid-insured youths in a Mid-Atlantic state. METHODS: Medicaid claims (2010-2014) were assessed among continuously enrolled youths in the 12 months before and after implementation of peer review. The study identified children ages zero to four preimplementation (N=118,815) and postimplementation (N=121,431), ages five to nine preimplementation (N=98,681) and postimplementation (N=107,872), and ages 10 to 17 preimplementation (N=154,696) and postimplementation (N=161,370). (Age ranges are inclusive of the final number). In each age group, multivariable logistic regression models with generalized estimating equations assessed the change in annual prevalence of antipsychotic use pre- to postimplementation. Use of other leading psychotropic classes and antipsychotic prescribing by medical specialty were also examined. RESULTS: The annual pre- to postimplementation prevalence of antipsychotic use decreased significantly, from .07% to .03% (adjusted odds ratio [AOR]=.41) among children ages zero to four, from 1.57% to .86% (AOR=.54) among those ages five to nine, and from 3.28% to 2.40% (AOR=.72) among those ages 10 to 17. With the exception of alpha-agonist use, which increased postimplementation (AOR=1.30) among those ages zero to four, no clinically significant pre-post change was noted in other leading psychotropic classes among children ages zero to four and 10 to 17. By contrast, postimplementation use of other psychotropic medications decreased among those ages five to nine (AOR=.73). CONCLUSIONS: A state Medicaid peer-review program resulted in decreased antipsychotic use across all age groups, particularly among children younger than ten. No notable substitution of other psychotropic classes for antipsychotics was observed.

Comparing Nurse Practitioner and Physician Prescribing of Psychotropic Medications for Medicaid-Insured Youths.

Objective: To describe psychotropic medication prescribing practices of nurse practitioners (NP) and physicians for Medicaid-insured youths in 2012-2014 in a mid-Atlantic state where NP independent prescribing is authorized. Method: From annual computerized administrative claims data in a mid-Atlantic state, we analyzed 1,034,798 dispensed psychotropic medications prescribed by NPs and physicians for 61,526 continuously enrolled Medicaid-insured youths aged 2-17 years. Demographic and clinical characteristics of psychotropic medication users were compared for youths who received psychotropic medication dispensings by NP-only, physician-only, or by both providers using descriptive statistics and generalized estimating equations. We then characterized psychotropic medication prescribing practices by providers within each specialty. Results: From 2012 to 2014, the number of psychotropic medication dispensings increased from 346,922 to 349,080. There was a 50.9% increase in the proportion of psychotropic medications prescribed by psychiatric NPs (from 5.9% to 8.8%) and a 28.6% proportional increase by non-psychiatric NPs (from 4.9% to 6.3%). By contrast, the proportion of psychotropic medications prescribed by psychiatrists and by non-psychiatric physicians declined (56.9%-53.0% and 32.3%-31.8%, respectively). Youths diagnosed with depression or anxiety were more commonly treated by NP-only than by physician-only (AOR = 1.33, 95% CI = 1.24-1.43), whereas youths with two or more psychiatric comorbidities were significantly more commonly treated by both NP and physician providers (AOR = 1.44, 95% CI = 1.39-1.50). Psychiatric specialists prescribed the bulk of antidepressants (82.0%) and lithium (92.3%), with much lower prescribing by non-psychiatric specialists (18.0% and 7.7%, respectively). Antipsychotic orders originated from psychiatric specialists 7.4 times more than from their non-psychiatric specialty counterparts, whether physician or NP. Conclusions: NPs, relative to physicians, have taken an increasing role in prescribing psychotropic medications for Medicaid-insured youths. The quality of NP prescribing practices deserves further attention.

Cardiovascular Events Following Treatment Initiation with Atypical Antipsychotic Medications in Publicly Insured U.S. Youth.

OBJECTIVE: To assess the risk of incident cardiovascular events that led to hospitalizations or emergency department visits following atypical antipsychotic (AAP) treatment initiation in youth according to dose, duration of use, and concomitant use of leading psychotropic medication classes. METHODS: We used computerized Medicaid claims to conduct a retrospective cohort study of youth (5-20 years) who initiated AAP treatment. AAP use was operationalized in a time-dependent manner according to current vs. former use, average daily dose (in risperidone dose equivalents), and duration of use. In a secondary analysis, concomitant use of (1) stimulants and (2) serotonin-reuptake inhibitors (SSRI/SNRIs) with AAPs was also assessed. To account for confounding, disease risk score methodology was used in discrete time failure models. RESULTS: There were 74,700 youth who initiated AAP treatment (average follow-up = 24.8 months). During follow-up, the risk of cardiovascular events was significantly greater during current than former AAP use (RR = 1.55, 95% CI = 1.09-2.21). Furthermore, for current users of AAPs, the risk of cardiovascular events intensified with average daily dose (RR = 2.04, 95% CI = 1.11-3.77 for >3.75 mg/day vs. ≤1.25 mg/day). The risk of cardiovascular events did not significantly differ according to duration of AAP use. In AAP-treated youth, concomitant SSRI/SNRI use was associated with an increased risk of cardiovascular events (RR = 1.61, 95% CI = 1.01-2.57). By contrast, stimulant use concomitant with AAPs was not significantly associated with an increased risk of cardiovascular events. CONCLUSIONS: In publicly insured U.S. youth, current AAP use was associated with an increased risk of incident cardiovascular events, which intensified with increasing dose and with concomitant SSRI/SNRI use. Prudent interpretation of these findings suggests that further research is needed to identify youth subpopulations with the greatest risk of developing AAP treatment-emergent cardiovascular events.

Psychotherapeutic medication prevalence in Medicaid-insured preschoolers.

OBJECTIVE: To update knowledge of the prevalence of the use of psychotherapeutic medications in preschoolers with Medicaid insurance as requested by the Best Pharmaceuticals for Children Act of 2002 (BPCA). METHOD: Prescription, enrollment, and outpatient visit data from 7 state Medicaid programs were used to identify 274,518 youths continuously enrolled in 2001 and aged 2 to 4 on January 1, 2001. Annual prevalence of use was defined as one or more dispensed prescriptions for a psychotherapeutic medication and adjusted for anticonvulsant and anxiolytic/sedative/hypnotic use according to ICD-9 diagnostic groupings. Prevalence ratios adjusted for age, race/ethnicity, and gender were estimated. RESULTS: 2.30% (CI = 2.24, 2.36) of preschoolers received one or more dispensings for a psychotherapeutic medication in 2001, approximately doubling the usage of comparable youth from 2 other state Medicaid programs studied in 1995. Boys were 2.4 times more likely than girls to receive psychotherapeutic medication. Whites were 4 times more likely than Hispanics and twice as likely as Blacks to receive medication for psychiatric or behavioral conditions. Since the mid-1990s, usage increased, especially for atypical antipsychotics and antidepressants. The prominent use of anticonvulsants (78.8%) and anxiolytic/sedative/hypnotic drugs (91.4%) in those with no psychiatric diagnosis, but with other medical diagnoses, shows that much use therein reflects treatment for seizures, rather than mood stabilization, and for minor medical conditions, rather than psychiatric disorders. CONCLUSION: Preschool psychotherapeutic medication use increased across ages 2 to 4 for stimulants, antipsychotics, and antidepressants, reflecting use for psychiatric/behavioral disorders. However, the use of anxiolytic/sedative/hypnotics and anticonvulsants was more stable across these years, suggesting medical usage. Additional research to assess the benefits and risks of psychotherapeutic drugs is needed, particularly when such usage is off-label for both psychiatric and nonpsychiatric conditions.

Differing antidepressant maintenance methodologies.

BACKGROUND: The principle evidence that antidepressant medication (ADM) is an effective maintenance treatment for adults with major depressive disorder (MDD) is from placebo substitution trials. These trials enter responders from ADM efficacy trials into randomized, double-blind placebo-controlled (RDBPC) effectiveness trials to measure the rate of MDD relapse over time. However, other randomized maintenance trial methodologies merit consideration and comparison. METHODS: A systematic review of ADM randomized maintenance trials included research reports from multiple databases. Relapse rate was the main effectiveness outcome assessed. RESULTS: Five ADM randomized maintenance methodologies for MDD responders are described and compared for outcome. These effectiveness trials include: placebo-substitution, ADM/placebo extension, ADM extension, ADM vs. psychotherapy, and treatment as usual. The placebo-substitution trials for those abruptly switched to placebo resulted in unusually high (46%) rates of relapse over 6-12months, twice the continuing ADM rate. These trials were characterized by selective screening, high attrition, an anxious anticipation of a switch to placebo, and a risk of drug withdrawal symptoms. Selectively screened ADM efficacy responders who entered into 4-12month extension trials experienced relapse rates averaging ~10% with a low attrition rate. Non-industry sponsored randomized trials of adults with multiple prior MDD episodes who were treated with ADM maintenance for 1-2years experienced relapse rates averaging 40%. CONCLUSIONS: Placebo substitution trial methodology represents only one approach to assess ADM maintenance. Antidepressant maintenance research for adults with MDD should be evaluated for industry sponsorship, attrition, the impact of the switch to placebo, and major relapse differences in MDD subpopulations.
