Bioterrorism Surveillance and Privacy
The threat of bioterrorism in the wake of the September 11, 2001, terrorist attacks cannot be ignored. Syndromic surveillance, the practice of electronically monitoring and reporting real-time medical data to proactively identify unusual disease patterns, highlights the conflict between safeguarding public health while protecting individual privacy. Both the Health Insurance Portability and Accountability Act and the Common Rule (which promulgate…
Cluster Randomized Trials
BACKGROUND: Cluster randomized trials (CRTs) offer unique advantages over standard randomized controlled clinical trials (RCTs) and observational methodologies, and may provide a cost-efficient alternative for answering questions about the best treatments for common conditions. OBJECTIVES: To describe health plan leaders' views on CRTs, identify barriers to conducting CRTs, and solicit recommendations for increasing the acceptability of CRTs. RES…
Effect of Increased Cost-Sharing on Oral Hypoglycemic Use in Five Managed Care Organizations
BACKGROUND: For patients with a chronic disease, increased cost-sharing for medications may lead to unintended consequences, including reduced use of medications essential for control of their disease. OBJECTIVE: The objective of this study was to estimate the effects of small ($1-6 per 30-day supply), moderate ($7-10), and large (>$10) increases in medication cost-sharing on 12-month trends in oral hypoglycemic (OH) use among adults with type 2 …
Risk Adjustment Using Automated Ambulatory Pharmacy Data
OBJECTIVES: Develop and estimate the RxRisk model, a risk assessment instrument that uses automated ambulatory pharmacy data to identify chronic conditions and predict future health care cost. The RxRisk model's performance in predicting cost is compared with a demographic-only model, the Ambulatory Clinical Groups (ACG), and Hierarchical Coexisting Conditions (HCC) ICD-9-CM diagnosis-based risk assessment instruments. Each model's power to forec…
Using Risk-Adjustment Models to Identify High-Cost Risks
BACKGROUND: We examine the ability of various publicly available risk models to identify high-cost individuals and enrollee groups using multi-HMO administrative data. METHODS: Five risk-adjustment models (the Global Risk-Adjustment Model [GRAM], Diagnostic Cost Groups [DCGs], Adjusted Clinical Groups [ACGs], RxRisk, and Prior-expense) were estimated on a multi-HMO administrative data set of 1.5 million individual-level observations for 1995-1996…
Community-Based Care and Risk of Nursing Home Placement
OBJECTIVE: To test the substitution hypothesis, that community-based care reduces the probability of institutional placement for at-risk elderly. RESEARCH DESIGN: The closure of the Social Health Maintenance Organization (Social HMO) at HealthPartners (HP) in Minnesota in 1994 and the continuation of the Social HMO at Kaiser Permanente Northwest (KPNW) in Oregon/Washington comprised a "natural experiment." Using multinomial logistic regression an…
The Sensitivity and Specificity of Forecasting High-Cost Users of Medical Care
OBJECTIVES: This study compares the ability of 3 risk-assessment models to distinguish high and low expense-risk status within a managed care population. Models are the Global Risk-Assessment Model (GRAM) developed at the Kaiser Permanente Center for Health Research; a logistic version of GRAM; and a prior-expense model. GRAM was originally developed for use in adjusting Medicare payments to health plans. METHODS: Our sample of 98,985 cases was d…
The Effect of Increased Prescription Drug Cost-Sharing on Medical Care Utilization and Expenses of Elderly Health Maintenance Organization Members
OBJECTIVES: The nature and extent of prescription drug benefits for the elderly are a continuing concern for health-care managers and policy makers. This study examined the impact of increased prescription drug cost-sharing on the drug and medical care utilization and expenses of the elderly. METHODS: Two groups of well-insured Medicare risk-based members of a large health maintenance organization (HMO) had their copayments increased in different…
An Empirical Analysis of Preferences in the 1983 Multicandidate Peruvian Mayoral Election
The 1983 four-candidate mayoral race in Lima, Peru, offers a chance to examine some notions from rational choice theory with empirical data. Data from a preelection Gallup poll test whether the winner-take-all plurality rule produced an undominated winner and an equilibrium result. The data produce a series of hypothetical pairwise races, assuming (by necessity) sincere voting and single-peaked preferences along an anti-incumbency dimension. Pref…
Age at first pregnancy in relation to age at menarche and year of birth in Caucasian, Japanese, Chinese and part-Hawaiian women living in Hawaii
A multiple regression analysis was undertaken to examine the relationship between age at first pregnancy and recollected age at menarche and sociological variables in Caucasian, Japanese, Chinese and part-Hawaiian parous women living in Hawaii. The analysis was conducted using the medical history records of 1198 Caucasian, 1770 Japanese, 453 Chinese and 578 part-Hawaiian women. Age at first pregnancy varied significantly among ethnic groups. Init…
