Health-related quality of life (HRQL) is a central concept for understanding the outcomes of medical care. When used in cost-effectiveness analysis, HRQL is typically measured for conditions persisting over long time frames (years), and quality-adjusted life year (QALY) values are generated. Consequently, years are the basic unit of time for cost-effectiveness analysis results: dollars spent per QALY gained. However, shorter term components of health care may also affect HRQL, and there is increased interest in measuring and accounting for these events. In radiology, the short-term HRQL effects of screening and diagnostic testing may affect a test's cost-effectiveness, even though they may only last for days. The unique challenge in radiology HRQL assessment is to realistically tap into the testing and screening experience while remaining consistent with QALY theory. The authors review HRQL assessment and highlight methods developed to specifically address the short-term effects of radiologic screening and testing.
健康相关生活质量（HRQL）是理解医疗保健结果的核心概念。在成本效益分析中使用时，HRQL通常针对长期（数年）持续存在的病症进行测量，并生成质量调整生命年（QALY）值。因此，年份是成本效益分析结果的基本时间单位：每获得一个QALY所花费的美元数。然而，医疗保健的短期组成部分也可能影响HRQL，并且人们对测量和核算这些事件的兴趣日益增加。在放射学中，筛查和诊断测试对HRQL的短期影响可能会影响一项测试的成本效益，尽管这些影响可能只持续几天。放射学HRQL评估中的独特挑战是在与QALY理论保持一致的同时，切实地了解测试和筛查体验。作者回顾了HRQL评估，并强调了专门为解决放射学筛查和测试的短期影响而开发的方法。
