Trial summary

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… Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Diabetic patients needing an ambulance for hypoglycaemic events and ambulance staff attending these events.

Who may be able to join

  • Patients: Adults aged 18 years+ with diabetes experiencing hypoglycaemia needing an ambulance service response. Hypoglycaemia for this study was identified as a 'clinical impression' of 'hypoglycaemia' or 'diabetic problem'. Hypoglycaemia may also be identified according to ambulance guidelines1 as any blood glucose less than 4mmol/L.
  • Clinicians: Ambulance staff providing treatment and advice to people who have had a hypoglycaemic attack.

Who cannot join

  • Patients: Children under the age of 18 years.
  • Clinicians: Ambulance staff providing treatment and advice for incidents other than hypoglycaemia.

About this study

Official title: Effect of Implementing an Ambulance Clinician Delivered Hypoglycaemia Intervention ('Hypos Can Strike Twice') on Repeat Ambulance Calls, Attendances and Transportation to Hospital: Non-randomised Stepped Wedge and Process Evaluation

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.

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.

Aims and objectives

Aim: To evaluate the effect 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. "Hypos can strike twice" is a complex intervention involving ambulance staff providing treatment and advice to people who have had a hypoglycaemic attack to access follow-up care by the GP or specialist diabetes team as detailed in national ambulance (JRCALC) clinical guidelines supported by the provision of a "Hypos can strike twice" booklet which the patient can read when they are fully recovered from the cognitive and other effects of the hypoglycaemic episode.

Objectives

To investigate the effect of implementing the 'Hypo's can strike twice' on:

  1. Repeat ambulance calls and attendances for hypoglycaemia
  2. Recorded referrals to an appropriate healthcare professional (e.g. GP, nurse).
  3. Completed care bundle for hypoglycaemia (proportion of patients with all of blood glucose recorded before treatment, blood glucose recorded after treatment and treatment given for hypoglycaemia.
  4. Costs of implementation 'Hypo's can strike twice' intervention vs costs of health service resource use.
  5. To conduct a process evaluation to explore how 'Hypo's can strike twice' exerts its effects and can be scaled up if effective by understanding implementation, mechanisms of impact, and contextual factors using interviews and surveys

Methods

Non-randomised stepped wedge design with mixed-methods process evaluation.

Study groups in NCT04243200
Study groupRoleWhat they receive
Analyses of repeat ambulance calls and costsFor our analyses of repeat ambulance calls and costs we will use routine anonymised data from routine call-and-dispatch and clinical records data from EMAS for 12 months before the intervention was first introduced (September 2017) to at least 6 months after the final step of the introduction in April 2019, i.e. October 2019. This is likely to involve the analysis of an estimated 11916 cases so that we can implement a stepped wedge (non-randomised control)design .
Receives: Other: Hypos can strike twice
Survey of patients receiving interventionWe will survey about 447 patients who received the intervention in order to obtain data from a sample of n=96
Receives: Other: Hypos can strike twice
Survey of ambulance staffWe will send out surveys/questionnaires to all front-line ambulance staff (n=approximately 600)
Qualitative interviews of staffWe will sample 10-15 staff for qualitative interviews.
Qualitative interviews of patientsWe will sample 10-15 patients for qualitative interviews
Receives: Other: Hypos can strike twice

What is being measured

The primary outcome is the main question the study is designed to answer.
