The purpose of the study is to develop and evaluate a new model for across services interaction with the use of welfare technology and telemedicine. The model includes innovative and new routines for the exchange of patient information, quality systems and procedures between the municipality and the hospital. This model will first be tested for use in intravenous antibiotic therapy. The results of the study will be used to further develop the service. In the larger context, it is desirable to provide knowledge that is transferable to other diagnostic groups, treatment methods and geographical areas.

This research-based innovation study has an evaluation approach with follow-up evaluation as the overall approach.

The pre-project was carried out with a qualitative approach under the auspices of SINTEF 2018/2019.

The main project consists of sub-study 1 and sub-study 2 (2020/2022).

Sub-study 1: The project use an iterative, user-centered service methodology with a qualitative approach. Here, SINTEF has the main responsibility for a qualitative summary after conducting interviews, observations and group discussions with patients, next of kins and health professionals regarding the development and testing / quality assurance of the new concept / service course for home treatment.

Sub-study 2: The approach here is quantitative. Descriptive data must be obtained from the hospital and municipal patient records, patient administration system (PAS) at Kristiansund hospital, alarm data from the Regional Response Center and pump log from the individual patient's infusion pump after home treatment.
