Value of improving patient safety: Health economic considerations for rapid response systems-a rapid review of the literature and expert round table

Objectives Failure to rescue deteriorating patients in hospital is a well-researched topic. We aimed to explore the impact of safer care on health economic considerations for clinicians, providers and policymakers. Design We undertook a rapid review of the available literature and convened a round table of international specialists in the field including experts on health economics and value-based healthcare to better understand health economics of clinical deterioration and impact of systems to reduce failure to rescue. Results Only a limited number of publications have examined the health economic impact of failure to rescue. Literature examining this topic lacked detail and we identified no publications on long-term cost outside the hospital following a deterioration event. The recent pandemic has added limited literature on prevention of deterioration in the patients' home. Cost-effectiveness and cost-efficiency are dependent on broader system effects of adverse events. We suggest including the care needs beyond the hospital and loss of income of patients and/or their informal carers as well as sickness of healthcare staff exposed to serious adverse events in the analysis of adverse events. They are likely to have a larger health economic impact than the direct attributable cost of the hospital admission of the patient suffering the adverse event. Premorbid status of a patient is a major confounder for health economic considerations. Conclusion In order to optimise health at the population level, we must limit long-term effects of adverse events through improvement of our ability to rapidly recognise and respond to acute illness and worsening chronic illness both in the home and the hospital.
