The Guttman scale and Saidin index are commonly used to measure the availability of expensive medical devices such as CT, MRI, and PET. However, they do not account for critical aspects that larger-sized hospitals have two or more per medical device (modality). This study developed an alternative measure of the aggregated estimates of technology availability in hospitals. The quantity-adjusted technology level (QATL) index - accommodates multiple medical technologies (modalities) and the number of hospitals’ installments - compared with the Saidin index. According to the results of the empirical study, the statistically significant factors between the Saidin index and the QATL index are not much different. However, it is noteworthy that the coefficients of Tobit regression analysis in the tertiary hospitals were slightly larger in the QATL index than in the Saidin index. Evidence shows that the QATL index was meaningful in measuring hospital input resources. Based on the empirical test, this paper discussed the construct validity of the QATL index and presented future research directions.
