In compared outcomes of two SSRIs order 100 ml mentat ds syrup visa treatment associates, a TCA discount 100 ml mentat ds syrup fast delivery medications mobic, and a stepped conducting a cost analysis, the first challenge is to decide approach that began with a TCA that was replaced with an which costs are relevant for the comparison. Once this hurdle were lifetime medical costs, QALYs, and cost per QALY has been cleared, then the issue arises of how costs will be gained. The analysis for a base case found that lifetime medi- assigned. For example, if prescription costs during hospitali- cal costs ranged from $15,348 to $16,669 per patient, that zation are included in a pharmacoeconomic analysis, how QALYs gained ranged from 14. Should it be based per QALY gained ranged from $2,555/QALY to $6,346/ on actual acquisition costs, charges, or cost-to-charge ratios QALY. The model allowed certain factors, such as compli- as a percentage of the entire hospital bill? Cost-benefit analysis values the denominator in Analyzing the results of pharmacoeconomic studies re- dollars and calculates a return on investment. Cost-benefit quires the evaluator to assess the types of costs included in analysis allows comparison of alternatives that lead to dis- each study. Large variations in results can be attributable similar outcomes. Should a hospital open a gift shop or to different cost components (25). In the medical treatment provide a vaccination program for influenza? One major com- invested in a gift shop, there is a return of $1. Thus the vaccination program would be the more culties in estimating the cost of such informal care. A disadvantage of cost-benefit analy- result, investigators may account for those costs absorbed sis is that it requires all consequences to be valued in dollars. These costs include In health care, valuing in dollars such consequences as life things such as pain and suffering. Intangible costs are even years gained and disability days avoided may be considered more difficult to value in monetary terms. In diseases where difficult or unacceptable by many people. There are, however, many issues that affect the In many cases they are not included. Additional analysis conduct and interpretation of pharmacoeconomic analyses. Some of the principal issues are discussed in the following One mechanism to quantify intangible costs is a willing- sections. The study was designed to compare Costs a new antidepressant with TCAs. The drugs had similar Valuation of costs in pharmacoeconomic analyses can be efficacy but different adverse event profiles. There are two primary issues: first, which costs were asked to rank a series of adverse effects and then to should be included in an analysis, and second, how should quantify the maximum amount they would pay for a new those costs be valued. The costs of inputs in a pharmacoeco- drug that reduced each adverse event. On average, partici- nomic analysis typically include direct medical costs, direct pants were willing to pay an additional $14 per month to nonmedical costs, and indirect costs. Direct medical costs reduce the risk of blurred vision from 10% to 5%. When include costs such as physician visits, hospitalization, emer- asked their willingness to pay to avoid multiple simultane- gency department use, and pharmaceuticals. Examples of ous side effects, the range was $23 to $77 per month. Discount- forts to monitor or treat side effects, acute hospital care, ing costs is a concept that reflects the 'time value of money. Discounting reduces the value of dollars that will be realized more than a year in the future to reflect a present value.
