Official Title ICMJE | Warm Homes for Elder New Zealanders: a Community Trial of People With COPD | |||
Brief Summary | Aim The purpose of this study is to evaluate whether fuel subsidies reduce exacerbations of COPD among people aged over 55, and therefore whether providing such subsidies is a cost-beneficial policy initiative. The Warm Homes for Elder New Zealanders Study enrolled community-dwelling people aged over 55 with moderate or worse COPD. Prior to the study commencing the houses were insulated (if feasible, & the house-owner agreed). Data were collected on the health and energy use of the participants. The households randomly assigned to the "early" intervention group had a subsidy to their power account their first winter in the study. The subsidy was the intervention and was designed to enable the participants, if they chose to do so, to keep their house warmer during the winter. |

Detailed Description | Warm Homes for Elder New Zealanders (WHEZ) Background Although there has been considerable recent work on the prevention, management and causes of Chronic Obstructive Pulmonary Disease (COPD), the contribution of housing has not been well researched. This is despite the socio-economic patterning of COPD (Maori women have the highest rate of COPD that has been recorded for any group of women), and the relationship between socio-economic deprivation and housing conditions. It is likely that improved heating would reduce exacerbations of COPD as:
The percentage of people over 65 in New Zealand will increase from 12% to 22% over the next 25 years. Therefore it will become increasingly important to find cost-effective ways of reducing the morbidity of the older age group. As COPD is a significant cause of morbidity amongst older people, this study investigates a potentially cost effective intervention to reduce both the likelihood of expensive hospital stays and improve the quality of life for older people. Aim To evaluate whether fuel subsidies reduce exacerbations of COPD among people aged over 55, and therefore whether providing such subsidies is a cost-beneficial policy initiative. Potential Benefits The potential benefits of the study include reducing the burden of disease. The patients and their caregivers may experience improved quality of life. Hospitals may experience fewer patients requiring treatment during the winter. A cost-benefit analysis will quantify the benefits. |
