简要总结
This study will assess the effectiveness the "Hypos can strike twice" intervention on people with diabetes experiencing hypoglycaemia (or "hypo", meaning low blood sugar). The intervention should help prevent recurrence of "hypos", improve patients' future health, reduce calls to ambulance services and thus reduce NHS pressures and costs.
Hypoglycaemia affects increasing numbers of people with diabetes. It is a side effect of treatment with insulin or certain tablets, where blood glucose (sugar) falls causing the brain to malfunction. In mild cases this can lead to sweating, drowsiness and confusion; in more severe cases, coma can occur needing medical assistance for recovery, and if prolonged can be fatal. It results in 1% of calls to ambulance services.
The "Hypos can strike twice" intervention involves ambulance staff providing treatment to patients experiencing hypos and advising them to access follow-up care by their GP/specialist diabetes team. This is backed up by giving patients a "Hypos can strike twice" information booklet which they can read when they recover.
Universities of Lincoln and Leicester are working with East Midlands Ambulance Service NHS Trust and patient groups on this study. The "Hypos can strike twice" intervention has now been implemented by ambulance services in Leicester, Northamptonshire, Nottinghamshire, Derbyshire and Lincolnshire from October 2018-May 2019.
The investigators will analyse data from the ambulance services before, during and after the introduction of the 'Hypos can strike twice' intervention to evaluate the effect of the intervention on repeat ambulance calls and attendances for hypoglycaemia and the costs and consequences of implementing it. The investigators will also interview/survey ambulance staff who provided the intervention and patients who received it, to understand how and why it works (or does not) and how, if it works, it could be scaled up over a larger geographical area. The duration of this study is 1 year.
详细描述
Research question
What is the effect on repeat ambulance calls and attendances for hypoglycaemia and what are the costs and consequences of implementing the 'Hypo's can strike twice' intervention to patients with diabetes and hypoglycaemia attended by East Midlands Ambulance Service NHS Trust in the East Midlands region of the UK?
Background
Severe hypoglycaemia (defined as cognitive impairment severe enough to require external assistance for recovery) frequently requires an ambulance resulting in Emergency Department attendance or hospital admission. Severe hypoglycaemia constitutes around 1% of 1.7 million emergency ambulance calls in England and Scotland resulting in 100 thousand paramedic attendances and estimated costs in England of £13.6 million annually. Hypoglycaemia is associated with adverse consequences including higher mortality, morbidity and health service costs due to hospital attendance/admission. It is also frightening for both patients and relatives and impairs quality of life and productivity, leading to poor long term control.
