Factors Associated with Attention Deficit Hyperactivity Disorder Medication Use in Community Care Settings.

OBJECTIVES: To examine patient- and provider-level factors associated with receiving attention-deficit/hyperactivity disorder (ADHD) medication treatment in a community care setting. We hypothesized that the likelihood of ADHD medication receipt would be lower in groups with specific patient sociodemographic (eg, female sex, race other than white) and clinical (eg, comorbid conditions) characteristics as well as physician characteristics (eg, older age, more years since completing training). STUDY DESIGN: A retrospective cohort study was conducted with 577 children (mean age, 7.8 years; 70% male) presenting for ADHD to 50 community-based practices. The bivariate relationship between each patient- and physician-level predictor and whether the child was prescribed ADHD medication was assessed. A multivariable model predicting ADHD medication prescription was conducted using predictors with significant (P < .05) bivariate associations. RESULTS: Sixty-nine percent of children were prescribed ADHD medication in the year after initial presentation for ADHD-related concerns. Eleven of 31 predictors demonstrated a significant (P < .05) bivariate relationship with medication prescription. In the multivariable model, being male (OR, 1.34; 95% CI, 1.01-1.78; P = .02), living in a neighborhood with higher medical expenditures (OR, 1.11 for every $100 increase; 95% CI, 1.03-1.21; P = .005), and higher scores on parent inattention ratings (OR, 1.06; 95% CI, 1.03-1.10; P < .0001) increased the likelihood of ADHD medication prescription. CONCLUSIONS: We found that some children, based on sociodemographic and clinical characteristics, are less likely to receive an ADHD medication prescription. An important next step will be to examine the source and reasons for these disparities in an effort to develop strategies for minimizing treatment barriers.

Specific Components of Pediatricians' Medication-Related Care Predict Attention-Deficit/Hyperactivity Disorder Symptom Improvement.

OBJECTIVE: The development of attention-deficit/hyperactivity disorder (ADHD) care quality measurements is a prerequisite to improving the quality of community-based pediatric care of children with ADHD. Unfortunately, the evidence base for existing ADHD care quality metrics is poor. The objective of this study was to identify which components of ADHD care best predict patient outcomes. METHOD: Parents of 372 medication-naïve children in grades 1 to 5 presenting to their community-based pediatrician (N = 195) for an ADHD-related concern and who were subsequently prescribed ADHD medication were identified. Parents completed the Vanderbilt ADHD Parent Rating Scale (VAPRS) at the time ADHD was raised as a concern and then approximately 12 months after starting ADHD medication. Each patient's chart was reviewed to measure 12 different components of ADHD care. RESULTS: Across all children, the mean decrease in VAPRS total symptom score during the first year of treatment was 11.6 (standard deviation 10.1). Of the 12 components of ADHD care, shorter times to first contact and more teacher ratings collected in the first year of treatment significantly predicted greater decreases in patient total symptom scores. Notably, it was timeliness of contacts, defined as office visits, phone calls, or email communication, that predicted more ADHD symptom decreases. Office visits alone, in terms of number or timeliness, did not predict patient outcomes. CONCLUSION: The magnitude of ADHD symptom decrease that can be achieved with the use of ADHD medications was associated with specific components of ADHD care. Future development and modifications of ADHD quality care metrics should include these ADHD care components.

Impact of Mental Health Comorbidities on the Community-Based Pediatric Treatment and Outcomes of Children with Attention Deficit Hyperactivity Disorder.

OBJECTIVE: Children with attention deficit hyperactivity disorder (ADHD) often exhibit psychiatric comorbidities, which may impact illness presentation, diagnosis, and treatment outcomes. Guidelines exist for dealing with these complex cases but little is known about how comorbidities are being handled in community pediatric settings. The purpose of this study was to evaluate how mental health comorbidities affect community physicians' ADHD care practices and patients' symptom trajectories. METHOD: Medical charts of 319 children presenting at primary care clinics for ADHD-related concerns were reviewed. Physician assessment and treatment behaviors were extracted and parents rated ADHD symptoms at the time of diagnosis and at 3, 6, and 12 months. Baseline ratings were used to group children, as no comorbid mental health condition, internalizing, or externalizing comorbid condition. Multilevel analyses compared community physician care behaviors and ADHD symptom trajectories across groups. RESULTS: Approximately, 50 percent of the sample met screening criteria for a comorbid mental health condition. For children diagnosed with ADHD and treated with medication, community physician care largely did not differ across groups, but children with internalizing comorbidities made significantly smaller improvements in inattentive and hyperactive/impulsive symptoms compared with children with no comorbidities. CONCLUSION: Children with ADHD and mental health comorbidities, particularly internalizing disorders, exhibit less robust response to ADHD medication and may require additional testing before starting medication and/or alternative treatment approaches. Potential barriers to conducting comprehensive assessments and to providing multi-modal treatment are discussed.

Impact of a Web-Portal Intervention on Community ADHD Care and Outcomes.

BACKGROUND: The quality of care for children with attention-deficit/hyperactivity disorder (ADHD) delivered in community-based pediatric settings is often poor. Interventions have been developed to improve community-based ADHD care but have not demonstrated that better care results in improved patient outcomes. The objective of this study was to determine whether an ADHD quality improvement (QI) intervention for community-based pediatric practices improves patient outcomes. METHODS: A cluster randomized controlled trial was conducted in which 50 community-based pediatric primary care practices (213 providers) were randomized either to receive a technology-assisted QI intervention or to a control condition. The intervention consisted of 4 training sessions, office flow modification, guided QI, and an ADHD Internet portal to assist with treatment monitoring. ADHD treatment processes and parent- and teacher-rated ADHD symptoms over the first year of treatment were collected for 577 patients. RESULTS: Intent-to-treat analyses examining outcomes of all children assessed for ADHD were not significant (b = -1.97, P = .08). However, among the 373 children prescribed ADHD medication, there was a significant intervention effect (b = -2.42, P = .04) indicating greater reductions in parent ratings of ADHD symptoms after treatment among patients treated by intervention physicians compared with patients treated at control practices. There were no group differences on teacher ratings of ADHD symptoms. ADHD treatment care around medication was significantly better at intervention practices compared with control practices. CONCLUSIONS: A technology-assisted QI intervention improved some ADHD care quality and resulted in additional reductions in parent-rated ADHD symptoms among patients prescribed ADHD medications.

Relationship Between Attention-Deficit/Hyperactivity Disorder Care and Medication Continuity.

OBJECTIVE: To describe the relationships between attention-deficit/hyperactivity disorder (ADHD) care practices and subsequent medication use. METHOD: A retrospective cohort from a random sample of medical records in 50 pediatric practices with 188 providers, including 1,352 children who started ADHD medication, was studied. Independent variables included physician behaviors related to medication titration and monitoring of treatment response. Primary outcomes were number of days covered with ADHD medication during the first year of treatment and time from starting medicine to the first 30-day gap in medication supply. Multilevel modeling and Cox proportional hazards regression models were conducted. RESULTS: Children had an average medication supply of 217 days in the first year. Half experienced a 30-day gap in medication supply in the first 3 months. Nearly three-fourths had a medication adjustment in the first year with the first adjustment usually being a dosage change. The average time to the first medication adjustment was over 3 months. Physician's first contact with parents occurred in the first month of treatment for less than half, with the average time being over 2 months. Little variation related to ADHD care quality was accounted for at the physician level. Early titration and early contact were related to greater medication supply and continuity of treatment. CONCLUSION: Earlier physician-delivered ADHD care (e.g., contact with parent after starting medication and medication adjustment) is related to greater medication supply and continuity. It remains to be determined whether interventions that improve the quality of titration and monitoring practices for children with ADHD would also improve medication continuity.

Variability in ADHD care in community-based pediatrics.

BACKGROUND: Although many efforts have been made to improve the quality of care delivered to children with attention-deficit/hyperactivity disorder (ADHD) in community-based pediatric settings, little is known about typical ADHD care in these settings other than rates garnered through pediatrician self-report. METHODS: Rates of evidence-based ADHD care and sources of variability (practice-level, pediatrician-level, patient-level) were determined by chart reviews of a random sample of 1594 patient charts across 188 pediatricians at 50 different practices. In addition, the associations of Medicaid-status and practice setting (ie, urban, suburban, and rural) with the quality of ADHD care were examined. RESULTS: Parent- and teacher-rating scales were used during ADHD assessment with approximately half of patients. The use of Diagnostic and Statistical Manual of Mental Disorders criteria was documented in 70.4% of patients. The vast majority (93.4%) of patients with ADHD were receiving medication and only 13.0% were receiving psychosocial treatment. Parent- and teacher-ratings were rarely collected to monitor treatment response or side effects. Further, fewer than half (47.4%) of children prescribed medication had contact with their pediatrician within the first month of prescribing. Most variability in pediatrician-delivered ADHD care was accounted for at the patient level; however, pediatricians and practices also accounted for significant variability on specific ADHD care behaviors. CONCLUSIONS: There is great need to improve the quality of ADHD care received by children in community-based pediatric settings. Improvements will likely require systematic interventions at the practice and policy levels to promote change.
