The U.S. Navy Surgeon General tasked the Center for Naval Analyses to evaluate the TRICARE demonstration project. This demonstration is an attempt to coordinate health care for the medical-eligible military population of 300,000 in the Tidewater area of Virginia. When TRICARE matures, it will integrate a series of military treatment facilities, a preferred provider network, and a health maintenance organization, under joint service management. The evaluation consists of a comparison of several measures of effectiveness, before and after TRICARE implementation. We will be comparing Tidewater with two other regions: southern California, which is under CRI (a managed care program), and North Carolina, which is under standard CHAMPUS. The evaluation will take about three years to complete. In the meantime, we have collected baseline data for Tidewater and the comparison sites. The purpose of this paper is to present the findings of the baseline analysis of access to, and satisfaction with, health care during the pre-implementation period. This is not an evaluation of TRICARE. The results will be helpful in interpreting subsequent changes in the components of the program after TRICARE implementation.

As part of the Tricare- Tidewater evaluation, CNA fielded a military beneficiary health care survey in the fall of 1992 to collect information on access, satisfaction, health status, and utilization. To supplement these data, and support the Tricare evaluation, we developed an administrative data set using claims data from the Civilian Health and Medical Program for the Uniformed Services (CHAMPUS), Biometrics records, and Medical Expense and Performance Reporting System (MEPRS) data. This administrative data set provides not only cost information but also detailed utilization records, including information about specific diagnoses and treatments. While working with the survey data, we observed internal inconsistencies in how people responded to the utilization section of the survey. These inconsistencies raised concerns about the veracity of the self-reported use measures. Given these concerns and the unique opportunity of having both survey and administrative measures of use for the same population, we thought it was appropriate to attempt to validate the self-reported utilization data against administrative records. In this paper, we compare the self-reported utilization data to the corresponding administrative utilization data, created from the CHAMPUS Quick Response Data File and Biometrics records, for a subset of our survey respondents. We look at incidences of overreporting and underreporting use in the survey data, and we attempt to explain these occurrences and the impact of this misreporting on aggre

To evaluate the TRICARE demonstration project in the Tidewater area of Virginia, we need to collect health care information about military beneficiaries that is not available from administrative records. We chose to acquire information on access, satisfaction, and health status from a mail survey. We conducted a baseline mail survey in the fall of 1992, before the start of TRICARE. We plan to conduct a follow-up survey in the winter of 1995. Our response rate for the baseline survey was lower than expected, with 38 percent of the adult beneficiaries responding. With high levels of nonresponse, one can never be sure that there isn't some degree of bias in the survey responses. Therefore, we feel strongly about trying to improve the response rate for the follow-up survey. We reworked our survey implementation plan and tested it on a small sample of Navy beneficiaries. We find that modifying the survey implementation process has a dramatic effect on the response rate. This paper discusses the modifications we made and how they specifically affect the response rate.

The Marine Corps provides Professional Military Education (PME) for its noncommissioned officers. Each level of training is designed to provide the leadership skills necessary for advancement in rank. This research memorandum shows that prior performance, time in grade, length to end of active service, and operational commitments affect the selection of eligible Marines into some of the resident courses.

The prevalence of alcohol and drug use in the Marine Corps and the effectiveness of programs to combat it are assessed in this study. The analysis is based on the answers to an anonymous survey administered to 18,000 randomly chosen enlisted and officer personnel. The survey results were compared to those of similar surveys in 1980 and 1982 to discern trends. The analysis showed that, while the proportion of drinkers has remained constant, the proportion of heavy drinkers declined by a factor of two from 1980 to 1983. Drug use showed an even sharper drop: from 37 percent of all Marines in 1980 to 17 percent in 1983. These trends are attributed to the Marine Corps education and urinalysis programs.

This is volume II of a two-volume report on the results of a study concerning alcohol and drug use in the Marine Corps. It contains eight appendixes presenting detailed data and analyses supporting the main text in Volume I. The questionnaire used in the survey is reproduced in appendix A; appendix B describes the survey methodology; appendix C contains tables giving the sizes of the populations and samples surveyed; appendix D addresses the accuracy of the results obtained from the survey; appendix E describes the composite measure, or index, developed for estimating the monthly consumption of alcoholic beverages; appendix F looks at the patterns of responses to the questionnaires and how consistent they were; appendix G contains tables showing the prevalence of alcohol and drug use by unit type, location, and pay grade; and appendix H shows the relationship between urinalysis test results and use of drugs at the time tested.

In this paper the feasibility of longer enlistment contracts for the Marine Corps was examined. In addition to reviewing the literature, the data concerning the effect of contract length on accessions and on attrition was examined. It was estimated that requiring an additional year of enlistment is equivalent to an 8-percent pay reduction. It was also found that attrition in the Marine Corps is not significantly affected by contract length. These findings show that the cost per useful service year for 5- and 6-year enlistments is generally lower than for 4-year enlistments.

A link between youths' attitudes toward military service and their subsequent enlistment behavior was tested. It was used to project DOD enlistments through the year 2000 under conservative assumptions. Enough qualified volunteers should be available to meet the DOD accession requirements programmed for the future.
