Influence of Office Systems on Pediatric Vaccination Rates.

This study seeks to better understand the impact of practice-level factors on up-to-date (UTD) rates in children. We compared practice-level vaccination rates for 54 practices to survey data regarding office practices for staffing, vaccine delivery, reminder-recall, and quality improvement. Vaccination rates at 24 and 35 months were analyzed using t tests, analysis of variance, and linear regression. Private practices and those using standing orders had higher UTD rates at 24 months ( P = .01; P = .03), but not at 35 months. Having a pediatrician in the office was associated with higher UTD rates at both 24 and 35 months ( P < .01). Participating in a network and taking walk-in patients were associated with lower UTD rates ( P = .03; P = .03). As the percentage of publicly insured patients decreases, the UTD rate rises at 24 and 35 months ( r = -0.43, P = .001; r = -0.037, P = .007). Reported use of reminder recall-systems, night/evening hours, and taking walk-in patients were not associated with increased UTD rates.

Unfilled prescriptions in pediatric primary care.

BACKGROUND AND OBJECTIVES: Filling a prescription is the important first step in medication adherence, but has not been studied in pediatric primary care. The objective of this study was to use claims data to determine the rate of unfilled prescriptions in pediatric primary care and examine factors associated with prescription filling. METHODS: This retrospective observational study of pediatric primary care patients compares prescription data from an electronic medical record with insurance claims data. Illinois Medicaid provided claims data for 4833 patients who received 16953 prescriptions during visits at 2 primary care sites over 26 months. Prescriptions were compared with claims to determine filling within 1 day and 60 days. Clinical and demographic variables significant in univariate analysis were included in logistic regression models. RESULTS: Patients were 51% male; most (84%) spoke English and were African American (38.7%) or Hispanic (39.1%). Seventy-eight percent of all prescriptions were filled. Among filled prescriptions, 69% were filled within 1 day. African American, Hispanic, and male patients were significantly more likely to have filled prescriptions. Younger age was associated with filling within 1 day but not with filling within 60 days. Prescriptions for antibiotics, from one of the clinic sites, from sick/follow-up visits, and electronic prescriptions were significantly more likely to be filled. CONCLUSIONS: More than 20% of prescriptions in a pediatric primary care setting were never filled. The significant associations with clinical site, visit type, and electronic prescribing suggest system-level factors that affect prescription filling. Development of interventions to increase adherence should account for the factors that affect primary adherence.
