Abstract
Background. Despite extensive professional debate regarding the optimal thrombolytic therapy strategy in acute myocardial infarction (AMI), patient preferences have not been explored. Methods. Preferences among patients with known or suspected coro nary artery disease for treatment with tissue plasminogen activator (tPA) or streptoki nase (SK) for AMI were determined using a questionnaire presenting GUSTO-1 trial and drug cost data. Preferences were based on consideration of 30-day mortality (M) alone, hemorrhagic stroke rate (SR) alone, overall preference (M + SR), drug acqui sition costs, and the estimated annual costs of using a single agent to treat all AMIs. Cost-related responses were provided under payer designations of self, third-party insurance, and federal government. Results. The response rate was 81% (101/125 patients). tPA was preferred by 84%, and SK by 66%, for M alone and SR alone, respectively (χ 2, p < 0.01). Overall preference (M + SR) favored tPA (78%, p < 0.01). tPA preference decreased to 43% considering drug acquisition costs under the self- pay option (p < 0.01 vs M + SR). Similar trends of lesser magnitude were also ob served for the third-party and government-payer options. Conclusions. Under condi tions of zero cost and consideration of mortality plus stroke-risk data, tPA was preferred overall due to its lower mortality. Introduction of drug-cost data significantly shifted the preference toward SK, particularly under the self-payer designation. Patient prefer ences for thrombolytic therapy in AMI indicate tradeoffs between clinical attributes and cost, and should assist in framing medical debate and decision making. Key words: patient preferences; thrombolytic therapy; acute myocardial infarction; streptokinase; tissue plasminogen activator.
