Responding to National Patient Safety alerts for valproate and topiramate drugs |
Two National Patient Safety alerts mandated new measures for the use of valproate (a series of drugs used to manage epilepsy and bipolar disorder) and topiramate (a drug used to treat migraine symptoms). A dashboard has been developed for clinical specialists to identify patients who need medication reviews as a result of these changes. More information: |

Understanding the causes of diabetic lower limb amputations |
This study aims to prevent unnecessary lower limb amputations linked to diabetes. This is done by reviewing areas of best practice and where improvements can be made to provide consistently better outcomes. It started in response to an NHS Resolution study in June 2022 which reviewed clinical negligence claims for diabetes and lower limb complications, focusing on understanding the causes of above-the-ankle lower limb amputations. These amputations often start with ulceration and so are potentially preventable. More information: NHS Resolution. |

Home monitoring to avoid hospital admissions |
Some patients with heart conditions and COPD can be monitored at home using specialist equipment. If their condition deteriorates, healthcare professionals are alerted to provide appropriate care. Population health management data is being used to target this remote monitoring for patients where it will have the greatest impact.

Impact of COVD-19 on Breast Cancer |
A study analysing the impact of COVID-19 on patient outcomes of women diagnosed with breast cancer before, during and after the height of the pandemic across Cheshire and Merseyside. The plan is to analyse data to determine the impact of COVID-19 on patient delays to diagnosis and treatment, stage at diagnosis, treatment type and 1 year mortality from date of diagnosis for each of the three referral pathways (primary, secondary, NHS Breast Cancer Screening Programme) considering age, ethnicity and social economic status. The aim is to review how NHS Cheshire & Merseyside reacted to COVID-19, with results to be presented to local cancer services. |

Safe and Well hot spots analysis |
Cheshire and Mersey Fire and Rescue Services are working with NHS Cheshire and Merseyside to proactively visit homes most at risk of having an accidental fire. The data required for this is already in place, but GP practices are being asked to sign a data sharing agreement to support this work. Once that is complete a dashboard will be created, giving properties risk scores based on health and wellbeing factors in the NHS data. This score is calculated internally in the NHS. Nobody from the fire services will be given access to identifiable personal information. |

Healthy Air for Healthy Lungs - Indoor Air Quality Improvement Project |
St Helens Borough Council and Warrington Borough Council are working to improve indoor air quality.
Around 250 households in areas of deprivation will be given an indoor air quality monitor, have an indoor air quality assessment and receive health education and advice. This will be specifically targeted to households with children aged two to 10 years old that have an underlying respiratory illness, such as asthma.
This research is funded by a grant from the Department for Environment, Food and Rural Affairs and will work across six Air Quality Management Areas - four in St Helens and two in Warrington. |

Beyond CYP Transformation Programme Population Health Planning |
Child social care data has been requested to make it easier to support young people with complex needs in health and social care settings.
The Beyond programme, which is leading the Appropriate Places of Care work across Cheshire and Merseyside, has identified pressures on systems as a result of young people being placed in settings not suited to meeting their needs.
Programmes of system-wide change are working on addressing this, with access to this data being part of that to alleviate previous challenges of getting it from individual providers. |

Networked Data Lab (NDL) – Elective Waiting List management and Housing and Health study |
The Data into Action Programme and the Civic Health Innovation Lab at Liverpool University are working with the Health Foundation to evaluate the impact of elective surgery waiting lists and housing on health.
This is part of a national study collaborating with four other university data labs.
The insights will be used to identify local Cheshire and Merseyside interventions to support waiting list management and improve the health of patients waiting for surgery.
