Patient and Societal Value Functions for the Testing Morbidities Index

Abstract: Background We developed preference-based and summated scale scoring for the Testing Morbidities Index (TMI) classification, which addresses short-term effects on quality of life from diagnostic testing before, during and after a testing procedure. Methods The two TMI value functions utilize multiattribute value techniques; one is patient-based and the other has a societal perspective. 206 breast biopsy patients and 466 (societal) subjects informed the models. Due to a lack of standard short-term methods for … Show more

“…12 A total of 10 attributes were assessed: (a) pain or discomfort before the test, (b) pain or discomfort during the test, (c) fear or anxiety before the test, (d) fear or anxiety during the test, (e) physical function after testing, (f) mental function after testing, (g) embarrassment during the test, (h) familiarity for cancer, (i) clinical history of breast biopsy or surgery and (l) overall satisfaction. The first six attributes (a-f) were strictly related to the procedures, whereas the latter (g-l) were not.…”

“…With use of the elicited values for each of the seven testing attributes, a TMI score was calculated for each patient's biopsy experience with the model described separately by Swan et al (13). The TMI instrument can be used to calculate three types of scores.…”

“…Preference-based or "utility" values for short-term health states, which are anchored on death (utility score = 0) and perfect health (utility score = 1.0) are useful for comparing different health states and are frequently used in cost-effectiveness analyses. With use of the models developed by Swan et al (13), these same 188 women had a mean preferencebased score for breast biopsy of 0.84 6 0.06. The psychometric and utility scores were strongly correlated (r = 0.94).…”

“…TMI was obtained before giving the results to patients to avoid biases related to the results of the examinations. According to previous works [10][11][12], TMI is a validated instrument for the assessment of short-term life quality related to diagnostic testing. It was slightly modified for the purpose of our study.…”
