Project Progress Update

Work Package One

Key Activities Completed

•       We have created a new dataset which has not previously existed. We identified addresses of 66,345 properties created through PD. Our dataset of PD addresses across England is now completed as far as we can take it.

•       We will now conduct some basic descriptive analysis of this dataset, e.g. number of homes created by each type of PD, average scheme size and so on.

•       We have begun the process of linking addresses to health data.

Current Status & Outputs

•       We will analyse issues such as access to green space, shops/services and morbidity (e.g. asthma prevalence) and mortality data.

•       We will profile the neighbourhood locations (e.g. neighbourhood deprivation data) to produce a portrait of PD housing across England and comparison with national average housing locations.

•       We will undertake additional enhanced analysis using WP2 survey data to explore in greater detail the health and well-being impacts of PDR housing participants. We will further explore the research question of what are the health needs of populations living in PD housing which cannot be obtained through data linkage with hospital episode statistics.

•       We will conduct additional analyses of health conditions using data collected on physical and mental health and subjective wellbeing that have been identified as key themes in the qualitative research.

Work Package Two

Key Activities Completed

• Quantitative Phase: A large-scale cross-sectional survey was successfully completed, collecting data from 1,029 residents across England.

• 
  Qualitative Phase: Rich qualitative data was gathered through:
  - 6 focus groups with 36 participants.
  - 75 semi-structured interviews and home assessments.

Current Status & Outputs

• The analysis of the WP2 data is complete, and the initial results are currently being disseminated and prepared for publication.

• Initial results have been successfully presented at two conferences. Several outputs are currently under review and in preparation for submission to peer-reviewed journals.
  We anticipate having further details on the final publication status and full findings available on the website soon.

Work Package Four

Key Activities Completed

•       Development of an integrated health impact and health-economic assessment framework linking indoor exposures and population health outcomes.

•       Identification and synthesis of epidemiological evidence, concentration–response functions, and baseline health data relevant to PD-related exposures.

•       Integration of WP4 methods with empirical monitoring data (WP2) and exposure modelling outputs (WP3).

 Current Status & Outputs:

•       The Analysis: Health risk and health-economic modelling are underway, integrating indoor exposure estimates with epidemiological evidence to quantify disease burden, mortality, and economic costs under baseline and alternative regulatory scenarios.

•       Publications Pipeline: Peer-reviewed manuscripts in preparation on (i) integrated health risk assessment of ambient air pollution in Great Britain and (ii) health-economic and policy-relevant cost–benefit analyses.
