[Change in patient satisfaction in outpatient chemotherapy unit--comparison in 2005 and 2008].

We investigated the influences of the treatment environment, in terms of the increased number of treatments, introduction of regimen assessment and registration system, and the levels of specialization of the concerned medical professionals on patient satisfaction. We compared our results with those of a previous survey conducted in the outpatient chemotherapy unit of Hirosaki University Hospital. The patients were satisfied with respect to the privacy considerations and waiting time. However, a decrease in the patient instruction time led to slightly lower patient satisfaction. We concluded that it is useful to evaluate the quality of treatment in terms of patient satisfaction in a hospital.

[Effect of preliminary medication on oxaliplatin hypersensitivity].

Oxaliplatin therapy is a standard treatment for advanced colorectal cancer, and oxaliplatin hypersensitivity is one of its side effects that should be particularly considered. In the present study, we observed a decrease in the incidence of oxaliplatin hypersensitivity since the introduction of preliminary medication involving the administration of escalated doses of steroids and the use of antihistamine agents. From the medical economics perspective, although the costs of the preliminary medication were generated, those for the treatment of oxaliplatin hypersensitivity, which were higher than the total cost of the preliminary medication, needed to be generated for all patients. Introduction of preliminary medication decreased the overall cost, since the medication decreased the incidence of hypersensitivity. Therefore, preliminary medication was recognized to be effective from the perspective of medical economics. The preliminary medication we introduced contributed to a safe, cost-effective, and high-quality treatment for advanced colorectal cancer by preventing oxaliplatin hypersensitivity.

[Survey on antiemetic therapy in ambulatory cancer chemotherapy and medical economics for standardization].

A cancer chemotherapy unit was established to support therapy for outpatients with cancer in Hirosaki University Hospital. It is essential to standardize antiemetic therapy, since a wide variety of the therapy provided to the unit from the diagnosis and treatment departments were conventional and empirical. We surveyed the use conditions and compatibility of the therapy based on reliable guidelines, and then considered the medical economics for standardization. In moderate-grade emetogenic chemotherapy, 5-HT(3) receptor antagonists tended to be used frequently instead of the recommended steroids. From this survey, the standardization of the cost of 5-HT(3) receptor antagonists and the relatively inexpensive steroids used in cancer chemotherapy might reduce either the nausea or vomiting suffered by patients with cancer and their economic burden as well.
