Association of lower continuity of care with greater risk of emergency department use and hospitalization in children.

CONTEXT: The benefits of continuity of pediatric care remain controversial. OBJECTIVE: To determine whether there is an association between having a continuous relationship with a primary care pediatric provider and decreased risk of emergency department (ED) visitation and hospitalization. DESIGN: Retrospective cohort study. Setting and Population. We used claims data from 46 097 pediatric patients enrolled at Group Health Cooperative, a large staff-model health maintenance organization, between January 1, 1993, and December 31, 1998, for our analysis. To be eligible, patients had to have been continuously enrolled for at least a 2-year period or since birth and to have made at least 4 visits to one of the Group Health Cooperative clinics. MAIN EXPOSURE VARIABLE: A continuity of care (COC) index that quantifies the degree to which a patient has experienced continuous care with a provider. MAIN OUTCOME MEASURES: ED utilization and hospitalization. RESULTS: Compared with children with the highest COC, children with medium continuity were more likely to have visited the ED (hazard ratio [HR]: 1.28 [1.20-1.36]) and more likely to be hospitalized (HR: 1.22 [1.09-1.38]). Children with the lowest COC were even more likely to have visited the ED (HR: 1.58 [1.49-1.66]) and to be hospitalized (HR: 1.54 [1.33-1.75]). These risks were even greater for children on Medicaid and those with asthma. CONCLUSIONS: Lower continuity of primary care is associated with higher risk of ED utilization and hospitalization. Efforts to improve and maintain continuity may be warranted.

Utilization and cost of health care services for children with attention-deficit/hyperactivity disorder.

BACKGROUND: Despite an increasing prevalence of diagnosed attention-deficit/hyperactivity disorder (ADHD) among children, the impact of ADHD on utilization and costs of health care services is largely unknown. OBJECTIVE: To examine differences in health care utilization and costs between children with and without ADHD. DESIGN: Retrospective matched cohort study conducted from January 1 to December 31, 1997. Setting. Health maintenance organization in western Washington State. PARTICIPANTS: Children aged 3 through 17 years who were continuously enrolled in the health maintenance organization and used services during 1997 were eligible. Children were identified with ADHD if they had a diagnosis of ADHD or a prescription for a stimulant medication using automated patient files. Children without ADHD were randomly selected as controls and matched 4:1 to children with ADHD on age and sex. OUTCOME MEASURE: Utilization and costs of specific categories of health care services. Results. A total of 2992 children (5.2%) were identified with ADHD. Children with ADHD incurred significantly greater per capita total costs ($1465 vs $690) than children without ADHD. Children with ADHD had 9.9 times more outpatient mental health visits (1.35/year vs 0.14/year), 3.4 times more pharmacy fills (11.25/year vs 3.30/year), and 1.6 times more primary care visits (3.84/year vs 2.36/year) than children without ADHD. The adjusted incremental costs were estimated to be $375 (95% confidence interval: $336-$416) for children with ADHD alone and $812 (95% confidence interval: $671-$973) for children with ADHD plus coexisting mental health disorders. CONCLUSIONS: Children with ADHD use significantly more health care resources and incur significantly higher costs than children without ADHD. Coexisting mental health disorders substantially increase the cost of treating ADHD. Resource allocation decisions should consider the contributions of primary care, outpatient mental health, and pharmacy costs to the overall costs of care for children with ADHD.

The association between greater continuity of care and timely measles-mumps-rubella vaccination.

OBJECTIVES: This study assessed whether greater continuity of care is associated with timely administration of measles-mumps-rubella (MMR) vaccination. METHODS: We studied 11,233 patients continuously enrolled in Group Health Cooperative (GHC) from birth to 15 months. We used a preestablished index to quantify continuity of care based on the number of primary care providers in relation to the number of clinic visits. MMR vaccination status at 15 months was assessed with automated immunization data systems at GHC. RESULTS: In a logistic regression model, both medium continuity (odds ratio [OR] = 1.20, 95% confidence interval [CI] = 1.08, 1.33) and high continuity (OR = 1.36, 95% CI = 1.22, 1.52) were associated with increased likelihood of being immunized by 15 months compared with patients in the lowest tercile of continuity of care. CONCLUSION: Greater continuity of care is associated with more timely immunization.
