The Retrospective Chart Review : Prevalence of Incidents Related to Brought-in Medicine / 社会薬学

<p>Consultations with patients who bring drugs, especially on the high risk drug list, to a hospital is an important role of pharmacists. However, many incident reports occur though pharmacists generally make an effort to check such medications. In Japan, incidents are mostly reported just in terms of numbers but not in terms of the prevalence of a target group. We aim to reveal the prevalence of incidents related to medicine brought-in by patients undergoing surgery in National Hospital Organization (NHO) hospitals. For our study, we extracted patients undergoing surgery who were prescribed antidiabetic agents from the Medical data bank (MIA) in NHO. Chart reviews were performed on patients to evaluate the number of incidents in relation to brought-in medicine. The prevalence of incidents of interest was 4.4% (41/931, 95%CL : 3.2-5.9%). Pre-avoidable incidents represented 56.1% (23/41, p<0.0001). We found that pharmacists play a role in making incidents less severe.</p>

Severe Bleeding and Perforation Are Rare Complications of Endoscopic Ultrasound-Guided Fine Needle Aspiration for Pancreatic Masses: An Analysis of 3,090 Patients from 212 Hospitals

BACKGROUND/AIMS: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for the pathological diagnosis of pancreatic masses, but patients are susceptible to severe bleeding and perforation. Because the incidence and severity of these complications have not been fully evaluated. METHODS: We aimed to evaluate severe bleeding and perforation after EUS-FNA for pancreatic masses using large-scale data derived from a Japanese nationwide administrative database. RESULTS: In total, 3,090 consecutive patients from 212 low- to high-volume hospitals were analyzed. Severe bleeding requiring transfusion or endoscopic treatment occurred in seven patients (0.23%), and no perforation was observed. No patient mortality was recorded within 30 days of EUS-FNA. The rate of severe bleeding in low-volume hospitals was significantly higher than that in medium- and high-volume hospitals (0.48% vs 0.10%, p=0.045). CONCLUSIONS: Severe bleeding and perforation following EUS-FNA for pancreatic masses are rare, and the procedure is safe.

The association of the number of comorbidities and complications with length of stay, hospital mortality and LOS high outlier, based on administrative data

<p><b>OBJECTIVES</b>With greater concern for efficient resource allocation and profiling of medical care, a case-mix classification was applied for the per-diem payment system in Japan. Many questions remain, one of which is the role of comorbidity and complication (CC) in grouping logic. We examined the association of the number of CC with the length of hospital stay (LOS) and hospital mortality as well as the proportion of LOS high outliers in 19 major diagnostic categories (MDCs).</p><p><b>METHODS</b>This study was a secondary data analysis embedded in a government research project, including anonymous claims and clinical data during a 4-month period from July 2002. Every 19 MDC, LOS, hospital mortality or proportion of LOS high outliers was compared by the number of CC and presence of any procedures.</p><p><b>RESULTS</b>From 82 special function hospitals, 241,268 patients were enrolled in this study. Among all patients, 50.5% were identified without any CCs, 32.4% with one or two, 13.4% with three or four, and 3.7% with over five CCs. The overall mean LOS was 22.15 days and hospital mortality 26.05 cases per 1,000 admissions. In any MDC, LOS and the proportion of outliers increased as the number of CC rose. The mortality rate increased prominently in the respiratory system and the hematology system.</p><p><b>CONCLUSIONS</b>This study demonstrated that the occurrence of more CC caused longer LOS and higher mortality in some major disease categories. Further study will clarify the association of the weighted CC with resource use through controlling procedures specific for MDC.</p>
