Feasibility Study of a Home Hospitalisation Strategy for Patients With Heart Failure (NWECHANCE)

NWE CHANCE Feasibility Study of a Home Hospitalisation Strategy for Patients With an Acute Episode of Heart Failure Using Integrated eHealth Applications.

This feasibility study is part of a larger interregional European project (NWE-Chance) financially supported by the 'Interreg North West Europe' program to develop and validate promising integrated eHealth applications combined with nanotechnology for hospitalisation of heart failure patients at home. For more information on this research project and the partners see http://www.nweurope.eu/nwe-chance

Patients participating in the NWE-Chance study will be transferred to their home supported by the integrated home hospitalisation platform and a daily visit by a specialised nurse. The home hospitalisation platform allows monitoring vital signs of patients by using the Sensium patch and a connected weighing scale and blood pressure meter of HC@home. Blood parameters like creatinine and potassium will be measured (daily) by using the Medimate lab-on-chip technology (more information below). Patients will get a smartphone to receive reminders for measurements of blood pressure and weight and will be able to see the evolution of their blood pressure and weight values. The patient application also contains educational information for the patient on home hospitalisation and on how to take the measurements correctly. Patients are treated by a team of specialised nurses under supervision of a cardiologist. The nurses visit patients at least once a day and are equipped with laboratory equipment and IV medication administering equipment. These devices and equipment are currently used in standard HF care and are not part of the newly developed home hospitalisation platform. Patients receive treatment similar to in-hospital treatment, according to the cardiologist's best knowledge and insight. In the case of Jessa Hospital, if there would be a need for IV medication during the home-hospitalisation period, this will lead to rehospitalisation of the patient and the ending of the intervention. In Isala, the nurses have a 24/7 duty service and can be called by patients or their relatives on their own initiative. In Jessa hospital and MUMC+, the nursing team can be contacted between 9 AM and 17 PM. During other hours, the patients can contact the cardiologist on call. In case of treatment failure or severe deterioration, patients will be transported to the hospital. In case of emergency, ambulances will transport patients to the hospital (conversion to regular hospitalisation). If in follow-up, condition worsens, the patient can be readmitted at home again. In theory, patients may undergo repeated hospitalisations at home. The home-hospitalisation period will last at least 5 days and can be extended, till a maximum of 13 days, after consultation of a cardiologist. Patient will be asked to fill in questionnaires to assess feasibility at the end of the home-hospitalisation period (last visit of nurse). At the last visit of the nurse, she will take all the devices with her.

The NWE-Chance feasibility study is an international, multicenter, single-arm prospective and interventional study.

The primary objective of the INTERREG NWE-Chance project is the development of an integrated home-hospitalisation platform and the assessment of the feasibility of a home hospitalisation strategy for heart failure patients.

The SUTAQ or the Service User Technology Acceptability Questionnaire is to measure acceptability and identify the characteristics of persons who were likely to reject technological health services Will be assessed after the home-hospitalisation in patients and staff. There are 20 questions that can be answered with 6 answer possibilities ranging from fully disagree to fully agree. These answered will be coded to numbers ranging from 1-6 (6 is fully agree, 1 fully disagree). The total score is 120 and the range for the score can be 20-120

SUS or the System Usability Scale will be used after the home-hospitalisation to assess the usability of the platform for the patients and staff. There are 10 questions in total with 5 answer possibilities ranging from totally agree to fully disagree. The answers will be coded to numbers (1-5) and 5 means totally agree and 1 is fully disagree. The total score is 50 and the range for the score can be 10-50

The satisfaction of the home-hospitalisation program questionnaire consist of 19 questions and will be used to assess the satisfaction of patients. There are 5 answer possibilities ranging from completely satisfied to very dissatisfied. The answers will be coded to numbers (1-5) and 5 means completely satisfied and 1 is very dissatisfied. The total score is 95 and the range for the score can be 19-95
