Variation in Rate of Attention-Deficit/Hyperactivity Disorder Management by Primary Care Providers

Prevalence of attention-deficit hyperactivity disorder (ADHD): systematic review and meta-analysis

BACKGROUND

The estimates of attention-deficit hyperactivity disorder (ADHD) prevalence across various studies are significantly variable, contributing to uncertainty in ADHD prevalence estimation. Previous systematic reviews and meta-analyses have attributed this variability primarily to the methodological characteristics of the studies, including the diagnostic criteria, source of information, and impairment requirement for the diagnosis.

METHODS

Review identified studies reporting ADHD prevalence in representative samples of children and adults in Europe and worldwide. Studies that were conducted in the general population were included. We focused on studies that report ADHD prevalence based on clinical diagnosis (clinical diagnostic criteria based on the Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases criteria, other diagnostic tools, such as various scales or interviews based on clinical diagnostic criteria). PubMed/Medline was searched to identify relevant articles published until 2024/2/01. The study was registered in PROSPERO (CRD42020200220) and followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic review and meta-analysis.

RESULTS

In total, 117 studies were subjected to full evaluation. In the meta-analysis, 103 studies representing 159 independent datapoints were included. The overall prevalence of ADHD in register studies was 1.6%, 95% CI [0.9; 3.0], in survey studies 5.0%, 95% CI [2.9; 8.6], in one-stage clinical studies 4.2%, 95% CI [2.9; 6.0], and in two-stage clinical studies 4.8%, 95% CI [4.0; 5.8].

CONCLUSIONS

Exact comparisons among studies with different diagnostic criteria and types of sampling can impact prevalence estimates. When comparing data from methodologically different studies, these factors need to be considered.

Progress and Pitfalls in the Provision of Quality Care for Adults With Attention Deficit Hyperactivity Disorder in Primary Care

OBJECTIVE

Quality care for attention deficit hyperactivity disorder (ADHD) in adults has lagged behind other psychiatric disorders. We sought to assess how the achievement of quality measures (QMs) for diagnosing and treating ADHD in adults has changed over time.

METHOD

We assessed 10 QMs in electronic health records (EHRs) from primary care and behavioral health clinics from 2010 to 2020 for 71,310 patients diagnosed with ADHD.

RESULTS

The achievement of QMs increased over time (p < .001). Some showed increases to high levels; others remained low throughout the observation period. No patients achieved more than six of 10 QMs in any year. Small but significant effects for sex, race, ethnicity, practice ownership, practice type, and age.

CONCLUSION

Increase in quality care from 2010 to 2020 along with clear evidence that more efforts are needed to improve quality of care for adults with ADHD seen in primary care.

Primary Care Diagnosis and Treatment of Attention-Deficit/Hyperactivity Disorder in School-Age Children: Trends and Disparities During the COVID-19 Pandemic

OBJECTIVE

The aim of this study was to assess rates of primary care provider (PCP) diagnosis and treatment of school-age children with attention-deficit/hyperactivity disorder (ADHD) during the COVID-19 pandemic compared with prepandemic years and to investigate disparities in care.

METHOD

We retrospectively analyzed electronic health records from all primary care visits (in-person and telehealth) of children aged 6 to 17 years seen between January 2016 and March 2021 in a community-based primary health care network (n = 77,298 patients). Study outcomes are as follows: (1) number of primary care visits, (2) number of visits with ADHD diagnosis (ADHD-related visits), (3) number of PCP prescriptions for ADHD medications, (4) number of patients with first ADHD diagnoses, and (5) number of first PCP prescriptions of ADHD medications. Interrupted time series analysis evaluated changes in rates of study outcomes during 4 quarters of the pandemic year (March 15, 2020-March 15, 2021) compared with prepandemic years (January 1, 2016-March 14, 2020). Patient demographic characteristics during prepandemic and pandemic years were compared.

RESULTS

ADHD-related visits dropped in the first quarter of the pandemic year by 33% (95% confidence interval, 22.2%-43.6%), returning to prepandemic rates in subsequent quarters. ADHD medication prescription rates remained stable throughout the pandemic year. Conversely, rates of first ADHD diagnoses and first medication prescriptions remained significantly lower than prepandemic rates. The proportion of ADHD-related visits for patients living in low-income neighborhoods was lower in the pandemic year compared with prepandemic years.

CONCLUSION

Ongoing treatment for school-age children with ADHD was maintained during the pandemic, especially in high-income families. Socioeconomic differences in ADHD-related care emphasize the need to improve access to care for all children with ADHD in the ongoing pandemic and beyond.

Caring for adolescents and young adults with attention-deficit/hyperactivity disorder in primary care: seizing opportunities to address youth mental health needs

PURPOSE OF REVIEW

To provide primary care providers (PCPs) with updated practical guidance around the assessment and management of attention-deficit/hyperactivity disorder (ADHD) in adolescents and young adults (AYA).

RECENT FINDINGS

Of the three different presentations of ADHD delineated in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the Predominantly Inattentive presentation is the most common among AYA. Multiple rating scales exist to assist clinicians in identifying ADHD symptoms and monitoring treatment effects. Importantly, ADHD frequently persists into adulthood with negative impacts in many life domains if left untreated. It is important for PCPs to provide support for AYA as they transition to adulthood, as treatment adherence often drops sharply at that time, and, once treatment is discontinued, it is rarely restarted. Further, clinicians should be aware of the negative psychological, behavioral, and social impacts that COVID-19 has had on AYA with ADHD.

SUMMARY

AYA with ADHD often seek care first from PCPs. However, diagnosis and management of ADHD among AYA are challenging, and many clinicians feel ill-equipped, creating concern that many youth may go undiagnosed and untreated. Despite these long-standing challenges, recent advances have opened up critical opportunities for PCPs to proactively address ADHD in primary care settings and make a profound impact on youth as they seek to realize their full potential.

Attention-Deficit/Hyperactivity Disorder in 2- to 5-Year-Olds: A Primary Care Network Experience

OBJECTIVE

To assess 1) rates of primary care provider (PCP) diagnosis of attention-deficit/hyperactivity disorder (ADHD) in young children, 2) documented PCP adherence to ADHD clinical practice guidelines, and 3) patient factors influencing PCP variation in diagnosis and management.

METHODS

Retrospective cohort study of electronic health records from all office visits of children aged 2 to 5 years, seen ≥2 times between 2015 and 2019, in 10 practices of a community-based primary health care network. Outcomes included ADHD diagnosis (symptom or disorder), and adherence to guidelines in 1) comorbidity documentation at or after ADHD diagnosis, 2) ADHD medication choice, and 3) follow-up of medicated patients. Logistic regressions assessed associations between outcomes and patient characteristics.

RESULTS

Of 29,408 eligible children, 195 (0.7%) had ADHD diagnoses. Of those, 56% had solely symptom-level diagnoses (eg, hyperactivity); 54% had documented comorbidities. ADHD medications were prescribed only to 4- to 5-year olds (40 of 195 [21%]); 85% received stimulants as first-line medication; 48% had follow-up visits within 2 months. Likelihood of ADHD diagnosis was higher for children with public or military insurance (odds ratio [OR] 1.94; 95% confidence interval [CI] 1.40-2.66; OR 3.17; 95% CI 1.93-4.96). Likelihood of comorbidity documentation was lower for older ADHD patients (OR 0.48; 95% CI 0.32-0.71) and higher for those with military insurance (OR 3.11; 95% CI 1.13-9.58).

CONCLUSION

PCPs in this network frequently used symptom-level ADHD diagnoses in 2- to 5-year olds; ADHD diagnosis rates were below estimated population prevalence, with evidence for sociodemographic disparities. PCP comorbidity documentation and choice of stimulant medications were consistent with guidelines. Rates of timely follow-up were low.

Developmental-Behavioral Pediatrics 13 Years After the First Board Certification: Evolving Subspecialty

OBJECTIVE

To examine and define the evolving subspecialty of developmental-behavioral pediatrics (DBP) by analyzing workforce surveys presubspecialty and postsubspecialty certification.

METHODS

In 2015, an electronic workforce survey was sent to the members of the American Academy of Pediatrics Section on DBP and Council on Children with Disabilities and the Society for DBP. Answers from the 1998 survey for respondents with subspecialty fellowship training were compared.

RESULTS

Compared with the 1998 group of 265 DBPs, the 368 DBPs in the 2015 group were older, more female, and more diverse. In both groups, ≥80% evaluated and treated autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and developmental delays, but significantly (p < 0.001) fewer cared for children with physical disabilities (e.g., cerebral palsy [58% to 41%], multihandicapped [53% to 39%], neonatal follow-up [47% to 31%], and spina bifida [26% to 13%]) and other disorders (e.g., failure to thrive and obesity/eating disorders [27% to 15%]). Time for new patient and return visits remained the same (1.5 hours and 0.7 hours). Pediatric generalists and family practice physicians initiated most referrals; fewer 2015 DBPs (p < 0.001) reported school districts (83% to 70%) and more reported pediatric subspecialty (57% to 77%; p < 0.001) referrals. Acknowledgment of the need for more community DBP specialists increased from 66% to 80% (p < 0.001).

CONCLUSION

Survey data indicated that the workforce is aging and changing. ADHD, ASD, and developmental delays are solidifying as the defining clinical focus of DBP. Current trends can identify training needs, facilitate recruitment, and advocate for system change to support the DBP workforce to respond to the great need.
