In this study, we investigated the effect of histamin H2 receptor antagonist (H2RA) or proton pump inhibitor (PPI) for the prevention of upper gastrointestinal lesions associated with low-dose aspirin. We carried out a retrospective study of 2811 patients who had been prescribed low-dose aspirin (Bayaspirin® 100 mg) for more than 30 days at Tokai University Hachioji Hospital from 2006 to 2008. We classified them into three groups: aspirin alone group (n=1103), aspirin with H2RA group (n=844) and aspirin with PPI group (n=864). Patients who developed upper gastrointestinal lesions were diagnosed with gastric ulcer, duodenal ulcer, gastritis or duodenitis by gastroscopy. We then compared the incidence of upper gastrointestinal lesions among the groups. The incidence in aspirin alone group, aspirin with H2RA group and aspirin with PPI group was 2.54%, 1.54% and 1.04%, respectively; that of aspirin with PPI group being significantly lower (p<0.05). Additively, the odds ratio (OR) of aspirin with H2RA group and aspirin with PPI group was 0.60 (95% confidence interval [95%CI]: 0.31-1.17) and 0.40 (95% CI: 0.19-0.86) as compared with aspirin alone group, respectively. The upper gastrointestinal lesions were developed within two years in all groups. Our results suggest that the combined administration of low-dose aspirin and PPI is effective for the prevention of upper gastrointestinal lesions associated with low-dose aspirin. Also, the pharmacists should be especially careful for upper gastrointestinal lesions development within two years after administration of low-dose aspirin, regardless of combined whether H2RA or PPI.

Low-dose aspirin-induced gastrointestinal lesions are becoming an important problem in clinical practice. In our investigation of such adverse effects, we obtained 4 important findings considered useful for physicians, as follows; 1) even when aspirin was given at a dose, the incidence rate of gastrointestinal lesions was higher than with other NSAIDs, 2) the odds ratios for gastrointestinal lesions induced by aspirin with a histamine H2 receptor antagonist and proton pump inhibitor were 0.6 and 0.4, respectively, as compared with aspirin alone, 3) it is difficult to administer aspirin, which exerts an antiplatelet effect, without inducing gastrointestinal lesions, and 4) these gastrointestinal lesions appears early, especially within 2 years after administration. We distributed a questionnaire to 41 physicians to confirm our findings, and compared high (n=20) and low (n=21) frequency aspirin prescription groups. The recognition rate of points 1 and 3 noted above in the high group was significantly elevated as compared to the low group, whereas there no significant difference in regard to the information in point 4 between the groups and the rate of recognition was low. Moreover, only 27% of the surveyed physicians were familiar with all 4 points. Prior to receiving this information, 17% of the physicians gave no related instructions their patients, which was reduced to 0% after receiving this information. Furthermore, 98% of those surveyed found the information to be useful. Our results suggest that these 4 points of information regarding potential adverse gastrointestinal effects of low-dose aspirin are useful for physicians.

In this study, we established a methodology to calculate the rate of overlooking a dispensing error (inspecting error rate) as a new index for the purpose of determining dispensing error and malpractice rates. Using data obtained from analyses of these error rates at our and two other hospitals, an inspecting error rate was calculated for each institution. Our results showed that inspecting errors occurred at a frequency 3-5 times greater as compared to dispensing errors at each of the examined hospitals. We concluded that construction of a higher quality safety management system would be enabled by incorporation of an inspecting error rate as a new index to evaluate medical safety in regard to dispensing of medicines and managing inspection accuracy.
