Digital Alerts for Sepsis: a Qualitative Study

Sepsis is a common cause of serious illness and death with an estimated 123,000 cases and 46,000 deaths in the UK each year. Similarly, high levels of sepsis have been reported internationally, and sepsis is recognised by the World Health Organisation as a global health priority. Many countries have nationwide sepsis action plans and all UK hospitals have set targets to rapidly diagnose and treat patients with sepsis. Timely appropriately targeted intravenous antibiotics have been shown to be effective in improving outcomes for patients, with a 4% increase in odds of mortality for every hour's delay in administration of intravenous antibiotics.

The need for rapid treatment has led to the development of clinical criteria and 'screening tools' have been proposed to identify patients with sepsis. These include Sequential (Sepsis related) Organ Failure Assessment (Sofa), Systemic Inflammatory Response Syndrome (SIRS) criteria and in England the National Early Warning Score (NEWS), which was developed by the UK Royal College of Physicians. In December 2017, an updated version of NEWS, NEWS2 was published, which is recommended by NICE and the Royal College of Physicians as the most effective screening tool for sepsis in the UK. Available tools are based on current observations which clinicians are able to take and quickly calculate a score, but there is a paucity of evidence as to which tool to use and their effect on patient outcomes.

Potential pathways for the effectiveness of alerts when clinical deterioration is due to sepsis are likely to include an increase in the proportion of patients receiving intravenous antibiotics in one hour, and other 'sepsis six' measures. Improved communication and changes in dialogue between healthcare teams has been suggested as an important pathway for improvements in clinical outcomes. In addition, the introduction of sepsis alerts is often accompanied by treatment plans as well as education and training activities. Little is known about the contribution of these and other potential mediators on the effectiveness of alerts.

Previous qualitative research with healthcare professionals has highlighted problems in identification and management of sepsis including limits in professionals' capacity to identify sepsis, difficulties in handover of patients and errors in communication. These studies highlight both the requirement for healthcare professionals to feel confident in their assessment of patients and for clinical and organisations structures to work efficiently to provide optimal patient care. Previous qualitative research with patients has reported on patients' decisions to seek help with symptoms, experiences of hospitalisation and how patients have managed life after surviving sepsis. Additional studies with caregivers have described the burden on those caring for sepsis survivors and their role in advocating for their loved ones. Another study has looked at the words patients and call handlers use to describe symptoms of sepsis when patients seek help. These topics can help inform how patients and clinicians could use and potentially benefit from the use of digital alerts in hospitals.

This study is part of a wider programme of work seeking to determine the effectiveness of the introduction of digital alerts to improve outcomes of patients with sepsis. This component of the work seeks to explore healthcare professionals' and patients'/family members' views and experiences of deteriorating patient/sepsis alert systems in hospitals. This work will be undertaken within at least some of the NHS Trusts involved in the wider programme of work (Royal Berkshire NHS Foundation Trust, Oxford University Hospitals NHS Foundation Trust, University College London Hospitals NHS Foundation Trust, Imperial College Healthcare NHS Trust, Chelsea and Westminster Hospital NHS Foundation Trust and Cardiff \& Vale University Health Board) and potentially additional Trusts if required.

This is a qualitative study which includes three methods of data collection; observation of healthcare professionals working in hospitals, one-to-one interviews with healthcare professionals and interviews/focus groups with patients/family members.

Healthcare professionals will include doctors, nurses and other professionals who use, or help implement, deteriorating patient/sepsis alerts in NHS hospital Trusts. Patients/family members will include patients recruited from NHS trusts and community settings, who have previously had sepsis or are family members of patients who have had sepsis.

Interviews and focus groups will include topics which may be upsetting for some patients/family members or healthcare professionals. All participants will be made aware of sources of support available to them through the NHS and other relevant organisations. Patients and family members will have the option of taking part in a focus group or an individual interview depending on what they feel comfortable with.
