13. The effect of Employee Assistance Programs use on healthcare utilization.
OBJECTIVE: To estimate the effect of Employee Assistance Program (EAP) use on healthcare utilization as measured by health claims. DATA SOURCES: A unique data set that combines individual-level information on EAP utilization, demographic information, and health insurance claims from 1991 to 1995 for all employees of a large midwestern employer. STUDY DESIGN:

15. Using Medicaid claims data to evaluate a large physician fee increase.
OBJECTIVE. This study demonstrates the use of Medicaid claims data in order to evaluate a threefold fee increase in physician fees for deliveries ($265 to $795), which the Maryland Medicaid program implemented in 1986. DATA SOURCES AND STUDY SETTING. The study used Maryland Medicaid claims data for years of service 1985-1988, and was done at the Maryland Dep

16. A more accurate method for measurement of tuberculocidal activity of disinfectants.
The current Association of Official Analytical Chemists method for testing tuberculocidal activity of disinfectants has been shown to be inaccurate and to have a high degree of variability. An alternate test method is proposed which is more accurate, more precise, and quantitative. A suspension of Mycobacterium bovis BCG was exposed to a variety of disinfect

17. FRAXA and FRAXE: Evidence against segregation distortion and for an effect of intermediate alleles on learning disability
There have been several claims of segregation distortion (meiotic drive) for loci associated with diseases caused by trinucleotide repeats, leading us to test for this phenomenon in a large study of the X-linked loci FRAXA and FRAXE. We found no evidence of meiotic drive in females and no convincing evidence in males, where the limitation of risk to daughter

18. Culture variability associated with the U.S. Environmental Protection Agency Tuberculocidal Activity Test Method.
Tuberculosis continues to be a major world health threat. The etiologic agent is among the vegetative organisms most resistant to chemical disinfection. Tuberculocidal efficacy testing for regulatory approval of chemical germicides has evolved considerably over the past decade. A method currently in use is the Environmental Protection Agency Tuberculocidal A

19. A suspension method to determine reuse life of chemical disinfectants during clinical use.
In-use testing of disinfectants is necessary to ensure efficacy over time. The current official procedure for testing disinfectants, the Association of Official Analytical Chemists (AOAC) use-dilution method, cannot be adapted to repeated sampling techniques of use-life testing. It is therefore necessary to use an alternative method when evaluating the activ

20. Self-recognition in primates: phylogeny and the salience of species-typical features.
Self-recognition has been explored in nonlinguistic organisms by recording whether individuals touch a dye-marked area on visually inaccessible parts of their face while looking in a mirror or inspect parts of their body while using the mirror's reflection. Only chimpanzees, gorillas, orangutans, and humans over the age of approximately 2 years consistently

21. Analysis of variations in mortality rates with small numbers.
OBJECTIVE. We present a Monte Carlo technique to evaluate if observed mortality rates differ from model-predicted rates for situations when the number of deaths is small. DATA SOURCES. We used Medicare hospital claims and model-predicted mortality rates from the Health Care Financing Administration (HCFA) for the 169 acute care hospitals in Georgia. The HCFA

22. Risk factors for radiogenic cancer: a comparison of factors derived from the Hanford survey with those recommended by the ICRP.
A model for cancer induction in man exposed to low doses of radiation and based on the analysis of a survey of workers from a nuclear fuel processing plant is examined and compared with that adopted by the ICRP to limit risks to radiation workers. It is shown that claims that ICRP has significantly underestimated the risk apply primarily to those exposed in

23. Factors affecting bargaining outcomes between pharmacies and insurers.
OBJECTIVE: To model the bargaining power of pharmacies and insurers in price negotiations and test whether it varies with characteristics of the pharmacy, insurer, and pharmacy market. DATA SOURCES/STUDY SETTING: Data from four sources. Pharmacy/insurer transactions were taken from Medstat's universe of 6.8 million pharmacy claims in their 1994 Marketscan da

24. Effects of the relative fee structure on the use of surgical operations.
OBJECTIVE. The goal is to develop a theoretical and empirical framework for investigating how the demand for an operation may be affected by the fee for the operation (the own-price) and by fees for other services provided by surgeons in the same specialty (the cross-price). The theory suggests an empirical test of whether surgeons create demand for surgery.
