“…In Mandarin Chinese, for example, the number “four” has a similar pronunciation as “death”, while the number “eight” sounds like a word for “wealth.” Research has shown that in China, hotel rooms with “eight” in the price received higher ratings, and stock traders decided more quickly and were more likely to purchase lots ending in the number “eight” [ 7 , 8 , 9 ]. The association of these numbers with their connotational homophones is similar to the respective fame and infamy of lucky “seven” and unlucky “13” in Western culture.…”

Background: Actinic keratosis (AK) is a pre-cancerous skin condition caused by sun exposure. Number bias, a phenomenon that occurs when meaning other than numerical value is associated with numbers, may influence the reporting of AK removal. The present study aims to determine if number bias is affecting healthcare providers’ documentation of patient-provider encounters. Methods: A single-center retrospective chart review of 1415 patients’ charts was conducted at the University of Cincinnati Medical Center. To determine if there was a significant difference between even and odd-numbered AK removals reported, an exact binomial test was used. The frequency of removals per encounter was fitted to a zero-truncated negative binomial distribution to predict the number of removals expected. All data were analyzed with RStudio. Results: There were 741 odd and 549 even encounters. Odd removals were reported at a significantly greater frequency than even p < 0.001. Age may be contributing to the observed number bias (p < 0.001). One, two, and eight were reportedly removed more frequently, while nine, 13, and 14 were reportedly removed less frequently than expected, respectively. Conclusion: Number bias may be affecting clinicians’ documentation of AK removal and should be investigated in other clinical settings.
