Alphanumeric vs. Numeric Token Systems and the Healthcare Experience: Field Evidence from Healthcare Delivery in India
通过在印度诊所的实地实验，研究字母数字令牌相比纯数字令牌如何影响患者的疼痛感知、等待时间感知和满意度，发现字母数字令牌通常改善体验，但存在边界条件。
Long wait times for patients are an important health policy issue in many countries, especially developing countries in which there is generally poorer health infrastructure, appointments are not very common, and the opportunity cost of competing life priorities is high. In this research, we examine via field experiments in health clinics in India whether providing numeric versus alphanumeric wait tokens can affect pain perceptions of patients and whether the type of tokens can also affect their wait-time perception and visit satisfaction. Our research provides initial evidence that alphanumeric tokens, in most cases, lead to lower pain perception, lower wait-time perception, and higher satisfaction levels with the healthcare system compared with numeric tokens. However, this is not always true; we also demonstrate boundary conditions when numeric tokens perform better and when the differences between tokens are attenuated. We conducted field experiments in three separate clinics and vary the type of tokens (numeric versus alphanumeric) used to test multiple token operationalizations in varied healthcare contexts. We explain our findings using the cognitive strategy of wait-time perception and discuss why this strategy is helpful for a developing country. This paper was accepted by Matthew Shum, marketing.
