[Efficacy of a Dexamethasone Dose Escalation Regimen with a Cumulative Dose for Preventing Oxaliplatin Hypersensitivity Reactions].

Oxaliplatin is a platinum complex antineoplastic agent widely used for chemotherapy of colorectal cancer. However, one of its side effects is hypersensitivity reactions, the incidence of which increases with a cumulative dose, thereby posing a difficulty to continue oxaliplatin use. Our hospital changed the premedication of oxaliplatin in August 2009 and September 2012. We retrospectively investigated the usefulness of these premedication changes. The results showed no significant difference in the incidence of hypersensitivity between the control group(12.1%)and the group receiving H1 and H2-blockers (12.3%); however, the incidence of hypersensitivity was significantly reduced in the group receiving increased dexamethasone based on the number of courses(2.7%). Therefore, our regimen was found to be effective in preventing hypersensitivity reactions to oxaliplatin.

[Changes in Medical Safety Interventions Conducted by Ward-based Pharmacists since the Introduction of Their Services in Complex Medical Ward].

Despite an increase in the number of reports on medical safety interventions conducted by ward-based pharmacists, only a few reports have classified intervention cases in detail. We classified and compared the types of medical safety intervention conducted by ward-based pharmacists since the introduction of their services. The interventions were classified into: cases that were identified by pharmacists or through asking questions about physicians' prescriptions before dispensing medications (active interventions); and those in which pharmacy technicians could contribute to medical safety by receiving inquiries from patients or healthcare providers (passive interventions). The numbers of the two types of intervention were compared. The number of interventions significantly increased after the introduction of ward-based clinical pharmacy services. Especially, the numbers of cases identified during ward rounds conducted by ward-based pharmacists (active interventions) and those identified by receiving inquiries from physicians or nurses (passive interventions) significantly increased, possibly because the collection of patient information was performed more efficiently by conducting ward rounds, and an environment where physicians and nurses can easily make inquiries to pharmacists was established after increasing the time pharmacists spend on hospital wards. The results demonstrate that the introduction of ward-based clinical pharmacy services has improved communication with patients, facilitated information-sharing among physicians, nurses, and other healthcare providers, contributed to the safer management of pharmaceutical operations, and increased interest of patients.

[Nutritional assessment employing the malnutrition universal screening tool for patients with colorectal cancer undergoing outpatient chemotherapy].

OBJECTIVE: We surveyed the nutritional status of patients with colorectal cancer undergoing outpatient chemotherapy using the malnutrition universal screening tool(MUST)to examine its usefulness and association with adverse events. METHODS: We examined the use of the MUST and the incidences of adverse events in 34 patients with advanced or recurrent colorectal cancer who had undergone outpatient chemotherapy between April and December 2010. RESULTS: The high-risk patients requiring nutritional care intervention comprised 47. 1%(16 patients)of the study population, and these patients exhibited significant decreases in body weight and body mass index. The incidences of appetite loss and fatigue were significantly higher in the high-risk group than in the low-risk group. DISCUSSION: Precautions against adverse events may prevent a worsening of the nutritional status of patients with colorectal cancer. Thus, nutritional assessment is necessary in patients undergoing outpatient chemotherapy. Furthermore, the MUST appears to represent a very useful simplified nutritional screening method for the nutritional management for these patients.
