It is desirable for pharmacists to confirm the laboratory data of individual patients before dispensing. However, it is difficult to dispense prescription medications after checking individual laboratory data for all patients due to time constraints. To assist in prescription audits, Shinshu University Hospital began including laboratory data on in-hospital prescriptions in April 2011. This study examined the impact of laboratory data included on in-hospital prescriptions on prescription questions. The contents of prescription questions after the inclusion of laboratory data on in-hospital prescriptions (October 1 - December 31, 2013) were compared with those before inclusion of laboratory data (October 1 - December 31, 2010). The rate of prescription questions was significantly higher after compared with before the inclusion of laboratory data (2.30％ vs 2.04％, respectively; P = 0.020). In particular, the number of prescription questions referring to laboratory data showed a 3.5-fold greater increase after the inclusion of laboratory data on inhospital prescriptions (P < 0.001). Prescription questions referring to laboratory data included on prescriptions were associated with a prescription revision rate of 65.6％. Prescription questions referring to laboratory data involved clarification of the doses of medications, such as levofloxacin and famotidine, in patients with impaired renal function. These results indicate that the inclusion of laboratory data on in-hospital prescriptions is useful for efficiently extracting those requiring clarification.
