Laboratory tests are responsible for a large percentage of health care expenses in the United States. In a retrospective study of the outpatient test ordering by residents for hypertensive patients between the years 1980 and 1986 at the Department of Family Medicine at the Medical University of South Carolina, we found great variability in laboratory test ordering as well as an association between personality as measured by the Myers-Briggs Type Indicator (MBTI) and test ordering. Introverts ordered more than extroverts, and intuitives ordered more than sensors. This association was confirmed by a multiple regression analysis controlling for potential confounders of test ordering, such as severity of disease, the presence of coexisting diabetes mellitus, the demographic characteristics of the patient population, and the number of initial evaluations for hypertension. Elucidation of a relationship between resident personality and laboratory test ordering has important implications for planning intervention strategies to reduce excessive laboratory test ordering in ambulatory care.
在美国，实验室检查占医疗保健费用的很大比例。在对南卡罗来纳医科大学家庭医学系1980年至1986年间住院医师为高血压患者开出的门诊检查单进行的一项回顾性研究中，我们发现实验室检查单的开具存在很大差异，同时还发现迈尔斯-布里格斯类型指标（MBTI）所衡量的性格与检查单的开具之间存在关联。内向者开具的检查单比外向者多，直觉型的人开具的检查单比感觉型的人多。通过多元回归分析控制检查单开具的潜在混杂因素，如疾病严重程度、是否存在并存的糖尿病、患者群体的人口统计学特征以及高血压的初始评估次数，证实了这种关联。阐明住院医师性格与实验室检查单开具之间的关系，对于制定干预策略以减少门诊护理中过度开具实验室检查单具有重要意义。
