New paper: Promoting health through housing improvements, education and advocacy: Lessons from staff involved in Wellington’s Healthy Housing Initiative

We know that poor housing conditions result in ill health for many New Zealanders, and we know which interventions are required to ensure good quality housing that supports health. Healthy Housing Initiatives intervene to improve the homes of kids who are hospitalised for illnesses that could be related to poor housing conditions. Some colleagues and I recently published and article which provides insights about housing and health, and explores views about the effectiveness of these Ministry of Health-funded programmes. The article is available open access here and a blog post summarising some our findings is below.

What can we learn from Healthy Housing Initiatives? New Evidence from the Wellington Well Homes scheme [repost from Public Health Expert] – Elinor Chisholm, Nevil Pierse, Cheryl Davies, Philippa Howden-Chapman

There is overwhelming evidence that  living in poor quality housing is devastating to health and that improving housing conditions can promote good health.  New Zealand research has shown how low indoor temperatures and mould impair children’s lung function (1,2), that almost 28,000 hospitalisations per year are for diseases potentially attributable to inadequate housing (3), that exposure to poor housing conditions is associated with increased risk of rheumatic fever (4), and that hazards and lack of safety features in the home increase the risk of injury (5). However, the good news is that there are effective interventions to reduce the harm caused by poor housing. These include: reducing draughts, installing insulation, and providing better heating and the money to pay for it. This increases indoor temperatures (6–8), which in turn improves respiratory symptoms. (1,7,8) Fixing up homes reduces the risk of injury (9) and providing better quality (public) housing reduces hospitalisations (10).

That’s why Healthy Housing Initiatives (HHIs) –  services aimed at improving the homes of kids who are hospitalised for illnesses that could be related to poor housing conditions –  make a lot of sense. Since  2013, HHIs have been rolled out in eight regions. In Wellington, for example, through Well Homes, low-income families are offered a visit from a health and housing assessor. The assessor will check out the home, offer tailored advice on heating and ventilation, and provide items such as beds, bedding, curtains, heaters, draught-stoppers, and mould-cleaning kits that can help make the home warmer or drier. If relevant they may offer to talk to the landlord to ask them to make repairs or improvements to the home. They can also refer on to other services, including public housing, insulation provision, budget advice, and an assessment by Work and Income to check households are receiving their full benefit entitlements. While the HHI services are funded by the Ministry of Health, the interventions offered, such as heaters, are funded by charities, so what’s offered depends on what different HHIs are able to fund.

Last year, we interviewed 21 staff members involved in delivering the Well Homes programme to learn about their experiences and to explore the advantages and challenges of this approach to health promotion. Participants reported really dire conditions in some cases – entering people’s homes, they could see grass through cracks in the floor, smell mould, and feel wet carpet through their socks.  Staff reported that providing items such as heaters, blankets and draught stoppers was useful because it enabled families to see an immediate improvement to their homes. As one participant explained, a heater is just a basic need to be warm, so it is going to impact them straight away”.  To another participant, the provision of such items was the “ethical” and “fair” approach to working with families:  “You don’t want to go talk to whānau about anything that we don’t have a solution for”. Other ways Well Homes workers were able to support clients were through sharing information on how to effectively ventilate and heat homes, in some cases tailoring their advice to fit in with the reality of people’s homes and budgets. As one participant explained, “we… advise around heating the most vulnerable person’s room if that’s the only place you can afford to heat.”

Other ways Well Homes helps is by advocating on behalf of clients – for example,, helping clients to access their Work and Income entitlements, or advocating to landlords to make improvements, sometimes through the Tenancy Tribunal processes. In the case of private landlords, it can be difficult. Participants reported that some landlords  “just often don’t see the point [of making improvements]”Participants blamed this on the lack of standards in the Residential Tenancies Act (RTA): “You can make suggestions but they don’t really have to do anything about it.”  In many cases, clients preferred that Well Homes workers did not contact landlords. As one participant explained, “there is a sense that if they try and rock the boat too much they will jeopardize their tenancy” Clients were particularly wary of asking for improvements if the tenancy relationship was under stress: “they won’t want to address it with the landlord especially if they are in rent arrears or they have asked for things before and they haven’t been done and they are worried about rent.” Participants noted that some people would be better served by public housing, yet long waiting lists meant that moving to public housing was not always a possibility. Participants also reported that some homeowners struggled to afford repairs that their homes urgently needed – while funding was available for insulation, for example, this was of no use if the roof leaked.

This study’s findings demonstrate that a programme that combines advocacy, practical interventions, and education for healthy housing, can make a real contribution to enhancing housing conditions. The literature suggests that the interventions provided by Well Homes, if implemented effectively, will contribute to improved health. However, our findings suggest that the lack of availability of social housing and wider systematic problems in the private rental housing market, as well as a lack of funding and regulatory support for housing improvements constrain the ability of HHI workers to do their jobs and effectively implement all the interventions that the housing requires. This limits the capability of this joint government and charitable programme to fulfil its potential. The recent changes to rental housing standards and new funding for housing improvements for homeowners may enhance the ability of HHI staff to improve the housing of Well Homes clients. It will be important to see whether they do. .

The perspectives of Well Homes workers shared in our article, some of which are summarized in this blog post, are likely to be useful in interpreting the results of our ongoing study, a quantitative analysis on the effects of the programme on children’s readmissions to hospital for housing-related health needs.
