title: Improving preventive service delivery through office systems.
abstract: OBJECTIVE
  Rates of childhood immunizations and other preventive services are lower in many practices than national goals and providers' own estimates. Office systems have been used in adult settings to improve the delivery of preventive care, but their effectiveness in pediatric practices is unknown. This study was designed to determine whether a group of primary care practices in 1 community could implement office-based quality improvement systems that would significantly improve their delivery of childhood preventive services. The study was part of a larger community-wide intervention study reported in a preceding study.
  
  
  METHODS
  All the major providers of primary care to children in 1 community were recruited and agreed to participate (N = 8 practices). Project staff worked on-site with improvement teams in each practice to develop tailored systems to assess and improve the delivery of immunizations and screening for anemia, tuberculosis, and lead exposure. Office-based quality improvement systems typically involved some combination of chart prescreening, risk assessment forms, Post-it prompts, flow-sheets, reminder/recall systems, and patient education materials. Office systems also often involved redistributing responsibilities among office staff.
  
  
  RESULTS
  All 8 participating practices created improvement teams. Project staff met with the practices 10 to 15 times over 12 months. After the period of office assistance, the overall rates for all preventive services except tuberculosis screening increased by amounts that were both clinically and statistically significant. Absolute percent improvements included: complete immunizations at 12 months, 7%; complete immunizations at 24 months, 12%; anemia screening, 30%; lead screening, 36%. The amount of improvement achieved varied considerably between practices.
  
  
  CONCLUSIONS
  Office systems and the principles of quality improvement that underlie them seem to be effective in improving the delivery of childhood preventive services. Important predisposing factors may exist within practices that affect the likelihood that an individual practice will make significant improvements. prevention, immunizations, improvement, office systems, primary care.
