What is Effect of Drug‐test Interactions on Length of Hospital Stay about?

## Abstract ## Purpose To evaluate the impact of drug‐laboratory test interactions on the length of stay of hospitalised patients. ## Methods Observational study of 404 discharges from the Internal Medicine Services of a tertiary hospital. Databases with information on general data, medication and tests performed were linked with the potential interactions described in the literature. This revealed the potential interactions between drugs and laboratory tests (PIDL) in each patient. Several linear regression models, adjusted for confounders, were performed to test the effect of both the number of PIDL and their influence on tests results (false positive/negative) on the length of stay. ## Results A total of 19 741 PIDL were detected; 5954 could give rise to __potential false positive__ (PFP) results and 8442 to __potential false negative__ (PFN) ones. Each PFP was related to an increase of 0.051 days in stay duration (CI95% 0.001–0.102) and each PFN to 0.045 days (CI95% 0.008–0.081). Globally, 303 and 380 days of hospitalisation could be attributed to __false positives__ and __false negatives__, which could account for 9.8% of the total stay of these patients. ## Conclusions These
