The effect of the affordable warmth programme on internal environmental variables and respiratory health in a vulnerable group: a randomised trial


Osman, L., Douglas, G., Ayres, J., (School of Medicine, Medical Sciences and Nutrition, University of Aberdeen) Ludbrook, A., (HERU) Kyle, G., Milne, K., (Castlehill Housing Association) Lyon, J. (Aberdeen City Council) and Mackenzie, M. (Aberdeen Royal Infirmary)


Following assessment, participants were randomised to immediate home improvements (central heating and/or insulation) or a waiting list control group. Both groups were followed up in terms of respiratory health, indoor environment and admissions. The economic evaluation compared the costs of the interventions with the benefits achieved. Health benefits were measured in terms of hospital admissions and symptom scores. The comparisons between groups were mainly insignificant on an intention to treat basis resulting from both a failure to take up home improvements in the intervention group and home improvements taking place in the control group. A before and after analysis of those who had improvements, regardless of allocation, showed improvement in symptoms but not in admissions. This study also found that relatively few of these chronically ill patients lived in houses with low energy efficiency and so there was relatively little scope for improvement.
