Reduce unequal access to prevention and follow-up. The State of London health chapter shows substantial borough differences in healthy life expectancy and premature cardiovascular mortality.

THE PLACE BEHIND THE OPPORTUNITY
The Greater London Authority's fourth Environment Strategy progress report documents the acceleration of the city's net-zero target to 2030 and work on buildings, neighbourhoods, resources, and adaptation. Policy guides discovery; retrofit customer demand and financing still need validation. Distinguish Greater London from individual boroughs, and strategic policy from service procurement.

RESEARCH HYPOTHESIS · TO VALIDATE LOCALLY
A proposed neighbourhood navigation service could help an authorised provider reconnect patients with preventive appointments and relevant community support. Begin with a specific missed-care pathway and a human team, not an unvalidated diagnostic promise.
An impact claim should survive a difficult question. Design the measurement before you design the success story.
Start in London. Define the people, geography and existing service before measuring a change.
Use the proposed experiment above as a starting question. Agree the local scope, duration, comparison and safeguards before beginning.
Ask what would have happened otherwise. Compare like with like and record how much uncertainty remains.
Completed appointments, time to follow-up, patient burden, and outcomes selected by the clinical team; assess differences between groups.
Protect patient confidentiality and clinical decision-making. A short access pilot cannot credibly claim to increase population life expectancy.

PUT IT IN PERSPECTIVE
WHO and the World Bank’s 2025 monitoring report estimates that 4.6 billion people lacked essential health-service access in 2023. Financial hardship estimates refer to 2022; publication year does not make either indicator a 2025 observation.WHO / World Bank
