Study indicates “encouraging” health benefits from Clean Air Zone

Research examining Bradford’s Clean Air Zone (CAZ) has uncovered “early evidence” of enhanced public health, potentially leading to cost savings for the NHS. The findings from Born in Bradford (BiB), a research initiative monitoring the health of the city’s inhabitants, indicated that approximately 600 fewer respiratory patients were consulting GPs monthly, on average, a year following the CAZ’s implementation. Prof Rosie McEachan, the report’s author, described these indications as “hugely encouraging” but emphasized their status as “interim findings”. The comprehensive research is projected to conclude in an additional two years. Implemented by Bradford Council in September 2022, the CAZ established daily fees for commercial vehicles with the highest emissions entering specific areas of the city. This initiative constituted a component of a broader clean air strategy for the city, encompassing additional measures like offering grants to entities such as businesses and taxi drivers for vehicle upgrades. The research contrasted a two-year span from 2018 to 2020, prior to the plan’s inception, with a comparable duration between 2021 and 2023. Subsequently, it examined the volume of patients consulting their GP or emergency departments for issues related to respiratory or cardiovascular health. The investigation revealed a monthly reduction of 598 GP appointments for patients experiencing respiratory health problems, alongside 134 fewer monthly consultations for individuals with cardiovascular concerns. Preliminary data suggested that the decreased demand on GP appointments might be saving the NHS over £30,000 every month. Prof McEachan stated that these findings held “very significant” importance for a city such as Bradford, which “historically has high levels of respiratory and cardiovascular ill health”. She commented: “By improving pollution levels, reducing pollution, we’re seeing this knock-on improvement in the health of the population and that’s resulting in reduced healthcare burden for our very hard-pressed NHS doctors and nurses who are on the front line.” Nevertheless, Prof McEachan emphasized that these were “interim findings” and, due to the overlap of some research with the Covid-19 pandemic, the team would require “another couple of years” to “fully disentangle” the effects of clean air policies. Previous investigations by BiB had indicated that air pollution might contribute to 35% of GP consultations for breathing difficulties and 49% of A&E visits. Dr Katherine Hickman, a Bradford GP and West Yorkshire respiratory lead, stated that surges in air pollution could be “absolutely debilitating” for certain patients. She remarked: “They’re getting more symptoms, they’re having to use their reliever inhaler more and more, to the point that they present acutely at their GP for a course of steroids, or worst-case scenario, ending up in A&E.“We know that if we reduce air pollution it has benefits across the board, but it really does benefit those patients whose symptoms are triggered by air pollution.” Bradford Council leader Susan Hinchliffe commented: “The Clean Air Zone is proving that we can improve air quality and our residents are staying healthier as a result.” For highlights from West Yorkshire, tune into BBC Sounds, view the most recent episode of Look North, or submit a story you believe warrants coverage here.
