Expert comments

Comments on this technology were invited from clinical experts working in the field and relevant patient organisations. The comments received are individual opinions and do not represent NICE's view.

Four experts were familiar with and had used this technology before. Two continue to use the technology.

Level of innovation

Three experts consider the technology to be innovative. One believed it was a new variation on current methods of increasing oxygen to a wound. None of the experts believed the technology to have been superseded. Two noted alternative oxygen therapies, including hyperbaric oxygen therapy and a spray designed to deliver porcine haemoglobin to a wound bed. Neither of the alternative therapies mentioned are used in standard care.

Potential patient impact

Three experts believed the technology has the potential to reduce healing times in non-healing wounds. Two considered that the technology offers an alternative for people with complex wounds who have limited treatment options. One expert believed the technology might reduce pain and infection rate but felt there is little robust evidence to support this. Two believed the technology engages patients and may increase compliance. One believed that NATROX results in better quality tissue closure and is less invasive that alternative therapies. All experts believed people with chronic non-healing wounds would most benefit from this technology.

Potential system impact

Two experts believed NATROX could reduce the number of hospital visits. One also said that antibiotic use and amputation could reduce, with an overall reduction in secondary care costs. One expert believed NATROX could save nursing time because of faster healing and a need for fewer dressings. All experts considered that the technology will be cost saving if it reduces healing time. One expert commented that the technology could have a positive impact by introducing advanced wound therapies into the community care setting. Three believed the technology could reduce burden on the healthcare system. All agreed that only basic training is needed.

General comments

All experts agreed that this technology would be in addition to standard care. Two experts commented that occasionally the tubing kinks. One described accidental detachment when people have accidentally pulled the tubing. The company explained how to position the device to prevent kinking or pulling on the tube. Two experts also commented that charging the device overnight can be inconvenient, and some are not confident charging or wearing the device. Two experts believed an issue with using the device might be identifying patients that could manage it.
