Costs and outcomes of improving population health through better social housing: a cohort study and economic analysis.

OBJECTIVES

We sought to determine the impact of warmth-related housing improvements on the health, well-being, and quality of life of families living in social housing.

METHODS

An historical cohort study design was used. Households were recruited by Gentoo, a social housing contractor in North East England. Recruited households were asked to complete a quality of life, well-being, and health service use questionnaire before receiving housing improvements (new energy-efficient boiler and double-glazing) and again 12 months afterwards.

RESULTS

Data were collected from 228 households. The average intervention cost was £3725. At 12-month post-intervention, a 16% reduction (-£94.79) in household 6-month health service use was found. Statistically significant positive improvements were observed in main tenant and household health status (p < 0.001; p = 0.009, respectively), main tenant satisfaction with financial situation (p = 0.020), number of rooms left unheated per household (p < 0.001), frequency of household outpatient appointments (p = 0.001), and accident/emergency department attendance (p < 0.012).

CONCLUSIONS

Warmth-related housing improvements may be a cost-effective means of improving the health of social housing tenants and reducing health service expenditure, particularly in older populations.
