Monitoring clinical activity at the bedside in the intensive care unit (ICU) can provide useful information to evaluate nursing care and patient recovery. However, it is labour intensive to quantify these activities and there is a need for an automated method to record and quantify these activities. This paper presents an automated system, Clinical Activity Tracking System (CATS), to monitor and evaluate clinical activity at the patient's bedside. The CATS uses four Microsoft Kinect infrared sensors to track bedside nursing interventions. The system was tested in a simulated environment where test candidates performed different motion paths in the detection area. Two metrics, 'Distance' and 'Dwell time', were developed to evaluate interventions or workload in the detection area. Results showed that the system can accurately track the intervention performed by individual or multiple subjects. The results of a 30-day, 24-hour preliminary study in an ICU bed space matched clinical expectations. It was found that the average 24-hour intervention is 22.0minutes/hour. The average intervention during the day time (7am-11pm) is 23.6minutes/hour, 1.4 times higher than 11pm-7am, 16.8minutes/hour. This system provides a unique approach to automatically collect and evaluate nursing interventions that can be used to evaluate patient acuity and workload demand.

The Intensive Care Unit (ICU) is a therapeutic place for monitoring critically ill patients. However, it is a stressful area for the patients and it is causing them great anxiety. Previous studies have identified three groups of stressors in ICU namely; physical, psychological and environmental. The aims of this study were to determine the ICU stressors as experienced by patients and to determine the level of stressors felt by patients in ICU. A cross sectional study was done on 70 patients from two tertiary hospitals in Malaysia. A face-to-face interview with structured questionnaire was used for patients. Data collection occurred from 15 December 2006 to 31 January 2007. The five major ICU stressors perceived by patients were pain, being stuck with needles, boredom, missing their spouses and being too hot/cold. The ICU physical stressors were the major items ranked by post ICU patients. The findings from this study provided a set of baseline information to the health care providers, particularly ICU nurses in Malaysia, with which to provide better care for the patients in ICU.
