Issues in the cross-national assessment of health technology.

With the growing international literature in economic evaluation and the rapid spread of new health technologies, there is a need to undertake, or at least interpret, economic evaluations on the international level. However, the ways in which cross-national differences affect the cost-effectiveness of health technologies or their evaluations have never been studied. This paper explores these issues by taking advantage of a unique situation in which the same economic evaluation of a new indication for a health technology was conducted simultaneously in four countries using an identical methodology. The study showed that if prior agreement on methods can be reached and local data applied, economic evaluations can be undertaken in a way that facilitates the extrapolation of results from country to country.

The cost effectiveness of auranofin: results of a randomized clinical trial.

In a 6-month randomized trial at 14 sites, the cost effectiveness of auranofin (AF) treatment for patients with rheumatoid arthritis was gauged in comparison with placebo. Measures of global health and of impacts on daily life suggest that the benefits of disease modification outweigh adverse effects after 4 and 6 months of treatment (p less than 0.01), with negligible differences between placebo and treated patients after 1 and 2 months. Additional medical costs directly associated with AF treatment amounted to $778/patient annually. Observed differences in less direct medical costs, help received, and earnings were not statistically significant.

The total cost of care and the use of pharmaceuticals in the management of rheumatoid arthritis: the Medi-Cal program.

Medicaid claims data were analyzed to investigate the prevalence and cost of rheumatoid arthritis (RA) in the Medi-Cal program. It was estimated that approximately 24,000 Medi-Cal recipients receive treatment for RA each year. The sample of Medi-Cal RAs studied averaged more than $2500 annually in total direct health care expenditures. The total cost of RA to Medi-Cal is projected to be $19.26 million (+/- $0.90 million) annually. Inclusion of possible gastrointestinal side effects of drug therapy increases the total cost to $20.49 million (+/- $0.91 million). While only 6.5% of the sample of RAs were hospitalized and 4.9% received nursing home care annually, these services are estimated to account for nearly 70% of RA-related expenditures. Less than 7% of Medi-Cal RAs receive disease modifying antirheumatic drugs (DMARDs). More than 75% of Medi-Cal RAs received aspirin or NSAIDs. These relieve pain and inflammation, but have not been demonstrated to halt the process of joint destruction.

Application of decision analysis to drug selection for formulary addition.

Decision analysis (DA) is a quantitative method for making decisions, incorporating both probabilistic data and value judgments, and clinical and economic outcomes. The P & T Committee at the Mary Hitchcock Memorial Hospital used this technique to aid in selection of a third-generation cephalosporin for formulary addition. Cost-specific data from this hospital, together with clinical data derived from the medical literature, and a panel of infectious disease specialists were used to compare costs associated with antibiotic regimens of three infections. Results show that ceftizoxime is the least costly treatment for hospital-acquired pneumonia and sepsis of unknown origin, whereas metronidazole plus gentamicin is the least costly regimen for intra-abdominal infections. This demonstrates that drugs with higher acquisition costs can, in some cases, be less expensive than drugs with lower acquisition costs when the total cost of drug therapy is considered.

Cost-effective choice of antimicrobial therapy for serious infections.

The authors evaluated the financial and health implications of treatment choices for three serious classes of infection: hospital-acquired pneumonia, intra-abdominal infection, and sepsis of unknown origin. Data were obtained from a systematic review of clinical literature and published data bases, by written questionnaire from a panel of infectious disease authorities, and from actual costs at a tertiary-care hospital. For pneumonia and sepsis, the third-generation cephalosporin evaluated (ceftizoxime) was found to be less expensive than other regimens, when costs of dose preparation and administration, monitoring, and toxicity were added to drug acquisition costs. The lowest-cost regimen for intra-abdominal infection was metronidazole plus gentamicin. Modest differences in efficacy would easily outweigh differences in toxicity, however, and could justify the use of more expensive regimens (e.g., mezlocillin plus gentamicin for hospital-acquired pneumonia, and cefoxitin plus gentamicin for intra-abdominal infection). If all regimens are assumed to be equally efficacious, then the third-generation cephalosporin was both lowest in cost and, owing to its low toxicity, greatest in net health benefit.
