'Scandalous' plans to move major trauma care from places like West Middlesex Hospital to hospitals in central London will put the lives of Hounslow residents at risk, according to health campaigners.
NHS London is currently carrying out a consultation into proposals that would see specialist trauma and emergency surgery located at just four sites - St George's in Tooting, St Mary's in Paddington, The Royal London in East London and Kings in Camberwell.
But health campaigners said the plans, which they claim will see a reduction in services currently available at hospitals like the West Mid, will leave Hounslow and Heathrow airport 'dangerously exposed'.
Geoff Martin, of London Health Emergency, said: "It would be a scandal if this was just bundled through without engaging in a proper debate around the impact on local acute hospitals like those grouped around Heathrow Airport."
The pressure group has warned the moves could undermine the ability of hospitals like West Middlesex to respond to a major incident at Heathrow.
"Patients will be driven past lesser A&E units to the new centres," added the group's information director Dr John Lister. "Services now provided in many units will be run down or closed.
"The plans make little logistical sense. Looking down this list of selected centres is like reading a roll call of the most congested access routes and over-crowded hospitals in the capital.
"None of the boroughs with the largest populations would be close to a trauma centre, nor would any of London's airports or motorways."
The worries come just a week after the resignation of West Mid's chief executive Tara Donnely following revelations that eight patients waited over 12 hours in A&E for a bed during a chaotic day last month.
And the Chronicle reported last August how similar fears about the West Mid's ability to cope in the wake of a plane crash or terrorist attack emerged following plans to shut its on-site sterlisation unit.
West Middlesex Hospital declined to comment on potential problems that may stem from the new structure should a major incident happen at Heathrow.
But a spokesman insisted no services will be cut, adding: "The consultation is about improving access to specialist major trauma care for Londoners."
Meanwhile, Sharon Day, NHS Hounslow's director of public health, said: "I believe that these proposals will save lives in Hounslow. Our residents deserve better access to life-saving treatment if they suffer a stroke or serious trauma.
"The Healthcare for London proposals will mean residents across London will be closer to both specialist stroke units, and major trauma centres."
