Continous Monitoring of Vital Signs on Hospitalized Cancer Patients.

Clinical Data Validation of a Novel Continuous Vital Sign Monitoring System in Cancer Patients Background The Cortrium C3 device is a novel, inexpensive, chest-worn unit designed for measuring vital sign parameters. The unit is capable of logging and wireless transmitting data describing pulse, respiratory rate, body surface temperature, ambient temperature and accelerometer data (1,2). The C3 device is developed as a diagnostic tool in the medical practice to meet the demand for a modern reliable and open medical grad vital sign monitoring system. The device is based on state-of-the-art technologies and is produced using high quality off-the-shelf components. Although, new technologies may be of high value to the health care system, studies show that the quality of technologies vary and more empiric data is needed to either support or reject the advantages of using intelligent health technologies at home (3-5). Besides measuring the actual quality of C3, it is therefore also important to evaluate how patients experience quality in relation to C3 in addition to an evaluation of perspectives from the health professionals. Objective The objective of the study is to validate measurements of pulse, frequency of respiration, and temperature obtained with the C3 device by comparison with routinely used hospital equipment. Further, the objective is to gain knowledge about how patients experience to be monitored with C3 and how hospital staff experience working with C3. Design and participants The study is carried out on cancer patients at the Department of Oncology, Naestved Hospital, Region Zealand, Denmark (DONZ). Collaborating partners are Cortrium, University College Zealand and Sundhedsinnovation Zealand. The study consists of a quantitative and a qualitative part. The quantitative study is a cross-sectional study of paired measures of vital sign parameters (pulse, respiratory rate and temperature) measured by the C3 device and standard hospital equipment used at DONZ. The qualitative study is planned as observational studies and semi-structured interviews with patients, who have been monitored with C3 and health professionals who have been involved in treatment or care of monitored patients. Recruitment of participants will take place amongst newly hospitalized patients at DONZ. It is planned to include approximately 40 patients in February and March 2016. Side effects, risks and inconveniences No major side effects are related to wearing and being monitored by the C3 device. The device has been tested on healthy volunteers and reports of inconveniences are mostly related to the adhesive ECG-electrodes that can irritate the skin. However, a wide array of electrodes are commercially available to fit the individual needs. Some might find wearing the device stigmatizing and/or inconvenient. In addition, the C3 device is marked CE class I. Hence, requirements for prevention of adverse effects are met. As an example, this includes two fuses between the battery and the electrodes, minimizing the risk of current for the battery entering the body even in the event of device failure. The device has not yet been approved for commercialization. Ethics and anonymization All data collected in the study is done according to the guidelines of Good Clinical Practice (GCP) for medical device studies (6). All data is anonymized, and is protected according to national law: "Lov om behandling af personoplysninger". The project has been reported to "Datatilsynet" \[the Data Protection Agency\]. Test subjects are secured access to further information about the study through their assigned nurse or email and telephone. Approvals The study has been approved by the Danish Ethical Comity: SJ-460, and The Danish Medicines Agency: journal number 2015120113.
