    Chemotherapy administration rates are increasing yearly. When administering chemotherapy, health professionals benefit from knowing the onset time, incidence rate, and severity of its various side effects; however, these factors are often unclear. We propose that obtaining sufficient information about side effects would make these factors clearer. In Shizuoka Cancer Center, medical professionals obtain patient-reported outcomes of the chemotherapy side effects via paper-based measures, and utilize that information in their clinical practice. Problematically, this information is not accumulated. Thus, we developed an integrated operation system to accumulate and manage information on patient-reported outcomes. This study evaluated the clinical application of this system.

    This system had three functions, as follows: (1) management and printing of information recording sheets; (2) reading mark sheets and uploading information into the database; and (3) analysis result indication. The recording sheets were paper-based mark sheets for collecting patient-reported outcomes, with each sheet recording the occurrence of ten types of side effects over a week.

    To evaluate the system, we obtained patient-reported outcomes for up to three courses of chemotherapy (regimen of cisplatin + pemetrexed) from thirteen patients with non-small cell lung cancer. The graphs of the results enabled us to accurately determine the onset time, change in incidence rate, and change in severity of side effects; they further illustrated the characteristics of each side effect and the differences among the courses. In conclusion, the system collects sufficient information to clarify the onset time, incidence rate, and severity of side effects. It therefore seems useful for evaluating the effects of supportive care for chemotherapy.

    As the population ages and the number of older people living alone in Japan increases, creating a society in which they can continue to live safely in their home environments became a pressing issue. Currently proposed IT-based monitoring systems have some drawbacks such as bothersome restrictions and psychological burden. Recently, several systems that monitor essential utilities, and that were non-restraining, non-intrusive, and automatic, have been proposed, but few reports have been made on longer-term experiments. Focusing on “tap water,” which is critical to maintain life and changes in living activities, this study conducted a one-year monitoring of the elderly living alone based on their water usage data. The subjects were 8 seniors of 75 and over living alone in a remote area (2 males, 6 females; average age 84.6±4.2; seven in treatment of cardiovascular diseases). The water flow measured in time unit of five minutes was recorded in the cloud server to monitor the elderly’s water usage. The purpose of this study was to monitor the water usage pattern of the elderly living alone and to verify the time unit proper to infer their daily living activities and patterns. Analysis was conducted to see how they use water in different time units (hour, week, month, and season). Analyzing the relations between the living activities to be studied and the time units for data aggregation identified the time units proper to infer daily living activities, indicating that the system could be effective as a tool to monitor independent living of the elderly.
