ElastoMeric Infusion Pumps for Hospital AntibioTICs

4 Background 4.1 Antibiotic resistance Antibiotic resistance (AMR) is when bacteria have changed (mutated) so they can survive the effects of antibiotics, meaning antibiotics are less effective. AMR is a major threat to health worldwide. In UK hospitals, at least a third of patients are on antibiotics at any given time. Hospital patients with serious infections are often given intravenous antibiotics (through a "drip" into a vein). Cutting down unnecessary antibiotic prescribing is key to reducing resistance.

4.2 Problems giving intravenous antibiotics Giving intravenous antibiotics takes a lot of nursing time. This is made worse if antibiotics are needed more than once a day. Nurses are the only staff who give intravenous antibiotics in hospitals, and there is a shortage of 40,000 nurses in the NHS. Because of this, it is common for doses to be missed. The COVID-19 pandemic has increased the pressure on nurses' time. It is not always practical to give antibiotics 4 or 6 times a day so less effective antibiotics may be used instead.

4.3 What can be done to help? Some antibiotics work better when given slowly into a vein all the time. EMPs are self-powered devices that deliver antibiotics in this way.

EMPs:

• are currently used to give antibiotics to patients in their own homes
• are not used to give antibiotics to patients in hospitals because the safety, benefits and value for money have not been confirmed
• could allow more nurse time for patient care by reducing the time to set up antibiotic drips.
• could make things better for patients by allowing them to move more, sleep better, recover faster and spend less time in hospital

4.4 Designs and methods used Patients who could have antibiotics through EMPs will be identified from clinical ward rounds. EMPs will be tested for safety in hospital patients, as well as value for money in the NHS by collecting information about costs, nursing time and length of hospital stay. Surveys of patients and nursing staff will be conducted to explore how EMPs could be best used in hospital.

4.5 Patient and public involvement (PPI) This research has been driven by patients who know how difficult it is to keep mobile when attached to drip stands; how disturbed sleep from drips being set up in the night affects their wellbeing; and, how they are concerned about missed doses of antibiotics. The project has been designed with input from a PPI representative (Co-investigator Thompson) who has reviewed all project plans and materials.

4.6 Dissemination Findings will be published in medical journals and presented at conferences/NHS patient events. Social media will be used to let people know what is found and infographics will be developed to help communicate findings using social media. If appropriate, funding will be sought for a full trial.
