N2  - Objectives 
    To determine if adherence to the recommended well-child care (WCC) visit schedule, independent of continuity of care (COC), is associated with lower risk of ambulatory care–sensitive hospitalizations (ACSH) and whether this association varies by chronic disease status.Design 
    Population-based, retrospective cohort study.Setting 
    Hawaii's largest health plan from 1999 to 2006.Participants 
    A total of 36 944 children aged 3.5 years or younger were eligible if they were enrolled prior to 2 months of age, had 4 or more outpatient visits during the study period, and had an enrollment period that overlapped with 1 or more WCC visit interval.Main Exposure 
    Patients' WCC visit adherence and COC index.Main Outcome Measure 
    Risk of ACSH (hazard ratio [HR]).Results 
    Overall, 8921 (24%) children had 1 or more chronic disease. The proportion of ACSH among healthy children vs those with 1 or more chronic disease were 3% (n = 751) and 7% (n = 645), respectively. For children with chronic disease, those with the lowest WCC visit adherence (0%-25%) had 1.9 times (HR, 1.9; 95% confidence interval [CI], 1.5-2.5) the risk of ACSH compared with those in the highest category (75%-100%). The risk of ACSH for children with chronic disease who fell into the lowest COC category (0-0.25) was 2.4 times (HR, 2.4; 95% CI, 1.7-3.5) higher than for those who fell into the highest category (0.75-1.0).Conclusions 
    For children with chronic disease, both low WCC visit adherence and COC are independently associated with an increased risk of ACSH. Providing access to a consistent source of primary care appears to be important to this vulnerable population.
