Smoking and consistently high use of medical care among older HMO members
Smoking behavior of consistently high and low users of medical care services were compared in two groups of older health maintenance organization (HMO) members continuously enrolled for five years and a subgroup who were continuously enrolled for 10 years. Smokers and former smokers, combined, were more likely than never-smokers to be consistently high users of ambulatory services (52 percent vs 34 percent in the five-year group, and 45 percent v…
Consistently High Users of Medical Care Among the Elderly
This study identified consistently high and low users of medical care services in a group of older HMO members continuously enrolled for six years. Consistently high users made up 26% of the sample, but accounted for more than 50% of total outpatient contacts and hospital admissions. Average ambulatory care costs were more than four times greater for the high users compared with the low users. Consistently high users were older than consistently …
Utilization Patterns and Mortality of HMO Enrollees
Data from a 6-year follow-up period were used to analyze the mortality of adults who had been continuously enrolled in a prepaid group practice health maintenance organization (HMO) for the previous 7 years. Thirteen percent of the HMO members were classified as consistently high users of outpatient care. Even after adjustment for age, sex, and cigarette smoking, this high user group's mortality rates during the follow-up period were significantl…
Utilization Patterns Among Long-term Enrollees in a Prepaid Group Practice Health Maintenance Organization
Criteria used in this study established that 13% of long-term adult members of a prepaid group practice health maintenance organization (HMO) were consistently high users of outpatient medical care services. This population accounted for 31% of the total doctor office visits (DOVs), 35% of the hospital admissions, and 30% of the outpatient surgical services for long-term members. The most frequent reason for DOVs in this high user group was treat…

Two-hundred-fifty alcoholics were randomly assigned to a full benefit of 50 per cent copayment group before entering an HMO (health maintenance organization) alcoholism treatment program. Data on use of treatment services, use of medical care services, and drinking behavior were collected for one year after intake. The medical care utilization and drinking behavior data were compared to data for the year before intake. The two coverage groups wer…

The effect of outreach workers' educational efforts on disadvantaged preschool children's use of preventive services
A special program of outreach services was implemented to assist a poverty population to appropriately use health services in the Kaiser-Permanente Medical Care Program. A study was conducted to determine the effect of outreach workers' intervention on the use of preventive services by this population. Intially, families were divided into two groups, one with and one without outreach workers. Outreach workers (neighborhood health coordinators) we…
The Effect of Length of Membership Upon the Utilization of Ambulatory Care Services
The relationships between duration of membership and the use of outpatient medical care services for disadvantaged and general membership groups in a prepaid group practice were analyzed. The effects of duration of membership upon utilization rates during a six-year study period were estimated by retrospective cohort analyses. Rates were computed for successive three-month intervals. There were no significant start-up effects on use for new enrol…
Health Status, Socioeconomic Status, and Utilization of Outpatient Services for Members of a Prepaid Group Practice
When evaluating the effectiveness of medical care programs, one concern is whether receipt of care is based upon health care needs or upon socioeconomic status. This study describes the relation between health status and socioeconomic status and attempts to determine which has the greater effect on ambulatory care utilization. The study setting was an operating HMO serving a cross-sectional membership of nearly 200,000 persons. Outpatient utiliza…
A Study of the Power Structure of the Medical Community
The specific objectives of this study were to analyze the structure and bases of power within a local medical community and to determine the extent to which power is unitary or differentiated. The study was based upon responses to a questionnaire given to the total population of physicians in private practice in Windsor, Ontario, Canada. The response rate for the defined universe was 91 per cent or 326 physicians. A definite order of influence ch…
Unscheduled Use of Ambulatory Care Services
The objectives of this study were to describe changes over time in unscheduled use of ambulatory care services and to identify factors related to unscheduled use. The study setting was a prepaid group practice designed to provide services primarily by appointment. The data were obtained from Health Plan and Hospital Operating Statistics, an ongoing utilization study and a household interview survey. A major increase in unscheduled use of outpatie…
Determinants of Medical Care Utilization
The importance of the telephone in the American medical care system is only beginning to receive appropriate attention. Fast studies indicate that a significant proportion of new diseases and a significant proportion of all medical care contacts take place by phone. A study of telephone use in a prepaid group practice system is presented. Data on telephone utilization are analyzed to determine the significance of telephone utilization of the popu…
