RESUMEN
AIM: We investigated adverse events (AEs) in a Japanese intensive care unit (ICU) and evaluated the impact of cause-specific AEs on mortality and length of stay. DESIGN: A retrospective observational study in the ICU of an academic hospital. METHODS: We reviewed medical records with the Global Trigger Tool. RESULTS: Of the 246 patients, 126 (51%) experienced one or more AEs with an incidence of 201 per 1000 patient-days and 115 per 100 admissions. A total of 294 AEs were detected with 119 (42%) adverse drug events, 67 (24%) procedural complications, 63 (22%) surgical complications, 26 (9%) nosocomial infections, 5 (2%) therapeutic errors and 4 (1%) diagnostic errors. Adverse event (AE) presence was associated with length of ICU stay (ß = 2.85, 95% confidence interval [CI]: 1.09-4.61). Adverse drug events, procedural complications and nosocomial infections were strongly associated with length of ICU stay (ß = 2.38, 95% CI: 0.77-3.98; ß = 3.75, 95% CI: 2.03-5.48; ß = 6.52, 95% CI: 4.07-8.97 respectively).

AIM: The Intensive Care Unit Trigger Tool (ICUTT) was developed to detect adverse events (AEs) in intensive care unit (ICU) patients. The purpose of this study was to determine the validity and reliability of the Japanese version of the ICUTT (ICUTT-J). METHODS: The translation of ICUTT was carried out based on the guideline for translation of instruments. Subsequently, two review teams independently reviewed 50 patients' medical records using the ICUTT-J, and agreement regarding the presence and number of AEs was evaluated to ensure reliability. RESULTS: The ICUTT-J was submitted to the authors of the original ICUTT, who confirmed it as being equivalent to the original version. The item-content validity index and scale-content validity index were 1.00 and 1.00, respectively. Interrater reliability showed moderate agreement of κ = 0.52 in terms of the presence of AEs and linear weighting of κ = 0.49 (95% confidence interval, 0.28, 0.71) in terms of the number of AEs. CONCLUSION: This study's findings suggest that the ICUTT-J is valid and moderately reliable for use in ICUs.
RESUMEN
Epirubicin hydrochloride(EPI)is well known to cause phlebitis as a typical adverse drug reaction. By preventing the development of severe phlebitis, patients are expected to continue effective chemotherapy with EPI without a decrease in QOL. We have previously reported promising results of a new injection method to prevent phlebitis from occurring during EPI therapy thorough a prospective clinical trial in our hospital(Jpn J Cancer Chemother 36: 969-974, 2009). In the present study, we have compared the conventional injection method(EPI main -route method, n=15)with our new method, which has been consistently practiced at present(EPI sub -route method, n=77). We found that in the EPI main -route method, angialgia/phlebitis developed in 14 of 15 cases(Grade 3, 53. 3%), leading to alteration of the regimen in 3 cases. On the other hand, with the EPI sub -route method, incidence of angialgia/phlebitis was markedly decreased, and only 6 of 77 cases developed these adverse reactions(Grade 3, 0%). One possible explanation for these results is that the reduction of intimal stimulation by the EPI sub -route method might be caused by the dilution and washout of EPI with pre-medication, as well as the shortened infusion times of EPI. Therefore, on the basis of the above hypothesis, we conclude that the EPI sub-route method might be a more effective treatment for the expected prevention of angialgia/phlebitis.

The efficacy of local steroid injection on the extravasation of vesicant anticancer drugs is controversial. In this study, the efficacy of local steroid injection was evaluated macroscopically and histologically in the extravasation models of doxorubicin (DXR), vinorelbine (VNR), and paclitaxel (PTX)in rats. Macroscopically, gross skin lesions were reduced by local steroid injections in rats treated with DXR and VNR. PTX did not cause gross skin lesions in most rats regardless of local steroid injection. Histologically, however, DXR, VNR, and PTX all induced deep tissue lesions such as edema, inflammation, and necrosis. Therefore, the effect of local steroid injection seemed to be minimal. In particular, DXR induced extensive necrosis in the subcutaneous and muscle tissues. VNR-induced skin lesions were milder than those induced by DXR, but had full thickness. Lesions caused by PTX were the mildest. These findings suggest that although local steroid injections could serve a primary role in diluting anticancer drugs and reducing gross skin lesions by their anti-inflammatory effect, they have less ability for suppressing deep-tissue lesions developing over time.

Many patients complain of venous pain or develop phlebitis following treatment with epirubicin hydrochloride(EPI). To ensure effective and safe treatment with this drug, it is essential to deal with the adverse events associated with it appropriately. At our hospital, EPI was previously administered by drip infusion(diluted with 50mL of physiological saline)over 15 minutes after pretreatment(EPI main route). With this method of treatment, venous pain and phlebitis developed in 14 of 15 cases. In 3 of these 14 cases, the regimen was modified. Following this experience, EPI administration was switched to drip infusion from the fully-opened side tube used for pretreatment(EPI sub-route). Switching to this route resulted in a sharp decrease in the incidence of venous pain and phlebitis, to only 1 of 15 cases. Stimulation of vascular tunica intima by EPI has been considered a factor principally responsible for the venous pain and phlebitis seen after EPI therapy. To prevent these adverse reactions, it is necessary to modify the method of administration so that strong or long-term exposure of blood vessels to EPI can be reduced. The results of this study suggest that the EPI sub-route we devised is useful in achieving this goal.
