Pulse Oximeters and the issue of Skin Colour: A PATIENT SAFETY ISSUE!
It is 2023 and years after the issue of bias in readings when it comes pulse oximeters and Black Skin was first raised, it has still not been fixed, leading to harm being caused to Black patients due to incorrect readings that lead to delayed or improper treatment.
“Since the start of the pandemic, the popular medical device has been indispensable for measuring oxygen in the blood, but dangerously inaccurate in patients with darker skin. Now the FDA is in the hot seat and Black researchers are working on a cure”.- Forbes
According to a recent article in Forbes by Amy Feldman , in one year alone, 11 hospitals in and around Baltimore had sent home 1,012 Black patients who had dangerously low, life threatening, low oxygen levels despite having normal readings on Pulse Oximeters! That alone should send shivers down our spines if you look at the numbers globally, since these devices are used worldwide.
This is even more shocking given that during the pandemic ( which is still ongoing, with long lasting effects), people were encouraged to buy pulse oximeters and keep them at home, as a safety measure, because it was found that one indication of deteriorating health, despite one feeling well, was a low oxygen saturation level. But we have since found out that, they give false readings when it comes to those of us with darker skin!
Although the article focuses on the American population and their own regulatory bodies i.e the FDA, this has far reaching implications for patients everywhere, even here in the U.K, given that these devices are used in every hospital and around peoples homes and also the fact that the UK government is moving healthcare to the home via ‘Virtual Wards’ , which rely on data produced by these devices and others linked to phones or smart watches. If the bias in reading is not fixed, then i fear that more harm will be caused to a population that is already bearing the brunt of medical racism! We have not even touched on Clinical Research Trials!
While some manufactures are tweaking their devices to correct this huge, life threatening anomaly, there is still a danger posed by pulse oximeters that are manufactured abroad and sold online on sites like Amazon and online stores with the danger being that they have not passed rigorous testing and approval by regulatory bodies like the FDA in America and the Medicines and Healthcare products Regulatory Agency (MHRA) here in the UK.
I hope that the MHRA will follow their American counterparts in holding the manufactures of these devices to account and also protect the public from defective, life threatening pulse oximeters that are sold online and in stores, by allowing only tested, regulated and licensed pulse Oximeters, to be used in all clinical settings ( Research Included), as well as in our homes( with regards to those purchased online).
We should not be harmed or worse still, die because of the Colour of our SKIN!
