ADHD: Overdiagnosed and overtreated, or misdiagnosed and mistreated?
ABSTRACT
In today’s changing medical climate, physicians need to treat attention-deficit/hyperactivity disorder (ADHD) better and more cost-effectively. The authors review recommendations supported by recent research and offer simple practices that integrate medicine and behavioral health for patients with ADHD.
KEY POINTS
- Despite concerns about overdiagnosis and overtreatment, many children and youth diagnosed with ADHD still receive no treatment or insufficient treatment.
- Today, more children are prescribed drug therapy when ADHD is diagnosed, but the initial titration of medication is often done without sufficient physician supervision.
- ADHD symptoms improve with drug therapy, but improvement is inconsistently sustained due to poor treatment adherence.
- Drug therapy and behavioral therapy work together. Outcomes can be determined by measuring both improved behaviors and reduced symptoms.
BEHAVIORAL INTERVENTION
Although opinions vary as to the advantages of drug therapy vs behavioral intervention in ADHD, there is evidence that a combined approach is best.30–33 Pharmacotherapy works inside the skin to reduce symptoms of inattention and overactivity, and behavioral therapy works outside the skin to teach new skills.
A report from the US Centers for Disease Control and Prevention in 2016 stated that behavioral therapy should be the first treatment for young children with ADHD (ages 2 to 5), but noted that only 40% to 50% of young children with ADHD receive psychological services.36 At the same time, the use of pharmacotherapy has increased tremendously.
Beginning treatment with behavioral therapy rather than medicine has been found to be more cost-effective over time. For children ages 4 to 5, behavioral therapy is recommended as the first line by the clinical practice guidelines of the American Academy of Pediatrics.14 Beginning treatment with behavioral intervention has been shown to produce better outcomes overall than beginning with medication and indicates that lower doses may be used compared with pharmacotherapy that is not preceded by behavioral therapy.37 Findings also indicate that starting with behavioral therapy increases the cost-effectiveness of treatment for children with ADHD.38
Behavioral intervention has modest advantages over medicine for non-ADHD symptoms,42 as the practice satisfies the adage “pills don’t teach skills.”26 One advantage is that caregivers take an active role in managing child compliance, social interactions, and classroom deportment, as opposed to the relatively passive role of prescribing medicine only. Parents and teachers form collaborative partnerships to increase consistency and extend the reach of change. In the National Institute of Mental Health multimodal treatment study, the only children whose behavior normalized were those who used medicine and whose caregivers gave up negative, harsh, inconsistent, and ineffective discipline43; that is, parents changed their own behavior.
Parent training is important, as parents must often manage their children’s behavior on their own the best they can, with little coaching and assistance. Primary care physicians may often refer parents to established local programs for training, and ongoing coaching can ensure that skills acquired in such training programs continue to be systematically applied. Pharmacotherapy is focused almost solely on reducing symptoms, but reducing symptoms does not necessarily lead to improved functioning. A multimodal approach helps individuals adapt to demanding settings, achieve personal goals, and contribute to social relationships. Outcomes depend on teaching what to do as well as reducing what not to do. Behavioral therapy44 shaped by peers, caregivers, teachers, and other factors can be effectively remediate the difficulties of children with ADHD.
The disadvantages of behavioral therapy are that it is not readily available, adds initial cost to treatment, and requires parents to invest more time at the beginning of intervention. But behavioral therapy reduces costs over time, enhances ADHD pharmacotherapy, often reduces the need for higher dosing, reduces visits to the doctor’s office, maintains behavior improvement and symptom reduction in the long term, and significantly increases quality of care.42
A RECOMMENDED ADHD CARE PATH
How do we increase quality of care, reduce costs, and improve value of care for patients with ADHD? The treatment of ADHD as a chronic condition is collaborative. Several practices may be combined in a quality care path.
Follow up more frequently at the start of drug treatment
Physicians may give more frequent attention to the process of pharmacotherapy at the start of treatment. Pharmacotherapy is typically introduced by the prescribe-and-wait method, which often produces less than optimal dosing, limited treatment adherence, and inconsistent outcomes.45,46 Though the cost of giving a prescription is low, the cost for unsustained treatment is high, and this undermines the usefulness of medical therapy. The simple solution is systematic titration through frequent contact between the prescribing physician and the parents in the first few weeks of pharmacotherapy. Subsequent ongoing monitoring of adherence in the first year is likely to reduce costs over time.47
Achieve optimal dosing
Pharmacotherapy should be applied with a plan in mind to produce evidence that optimal dosing has been achieved, ie, improvement is consistently observed in school and home.48
If side effects occur, parents and physician must determine whether they outweigh the benefits. If the benefits outweigh the side effects, then the physician and parents should maintain treatment and manage side effects accordingly. If the side effects outweigh the benefits, the titration process should continue with different dosing or delivery until optimal dosing is achieved or until the physician determines that pharmacotherapy is no longer appropriate.
Though different procedures to measure optimal dosing are available, medication effectiveness can be determined in 7-day-per-dose exposure during a period when the child’s schedule is consistent. A consistent schedule is important, as medicine effects are difficult to determine during loosely defined schedules such as during school vacations or holidays. Involving multiple observers is important as well. Teachers, for example, are rarely consulted during titration49 though they are excellent observers and are with the child daily when medication is most effective.
