To evaluate whether quality improvement (QI) capacity-building in affiliated primary care practices could increase well care visit uptake.

Partners For Kids (PFK) is an accountable care organization caring for pediatric Medicaid beneficiaries in Ohio. PFK QI specialists recruited practices to develop QI projects around increasing well care visit rates (proportion of eligible children with well care visits during calendar year) for children aged 3-6 years and adolescents. The QI specialists supported practice teams in implementing interventions and collecting data through monthly or bimonthly practice visits.

Ten practices, serving more than 26 000 children, participated in QI projects for a median of 8.5 months (IQR 5.3-17.6). Well care visit rates in the QI-engaged practices significantly improved from 2016 to 2018 (P < .001 for both age groups). Over time, well care visit rates for 3- to 6-year-old children increased by 11.8% (95% CI 5.4%-18.2%) in QI-engaged practices, compared with 4.1% (95% CI 0.1%-7.4%) in non-engaged practices (P = .233). For adolescents, well care visit rates increased 14.3% (95% CI −2.6% to 31.2%) compared with 5.4% (95% CI 1.8%-9.0%) in QI-engaged vs non-engaged practices over the same period (P = .215). Although not statistically significant, QI-engaged practices had greater magnitudes of rate increases for both age groups.

Through practice facilitation, PFK helped a diverse group of community practices substantially improve preventive visit uptake over time. QI programs in primary care can reach patients early to promote preventive services that potentially avoid costly downstream care.
