back to article 'Computer algo' blamed for 450k UK women failing to receive breast screening invite

Up to 270 women in the UK could have died of cancer due to a "computer algorithm failure" dating back to 2009 under the NHS' breast screening programme - British health secretary Jeremy Hunt said today. In a Parliamentary statement, Hunt said nearly half a million women between the age of 68 and 71 were not invited to their …

    Death by Computer

    What a time to be alive....... I'm sure some tech will end up taking the fall for this. Ignoring that they were probably under totally unreasonable time constraints and mismanagement.

    I bet they won't even be able to produce specification documentation for the project, leave out dreams like comprehensive testing reports.

    Sooner or later the IT industry will have its Harrow and Wealdstone rail crash incident and some probably really crap regulation will follow.

      It's not as simple as that. Screening is... screening. It gets you sent on for further investigation and tests, not straight on to treatment. Yes, there will still be false positives at the end of that process, but not at the screening false positive rate. That's the kind of thing you take into account when you decide whether to do a screening programme.

      Re: The real question is...

      I would have to say that your numbers are rather doubtful given that unless there are additional checks such as biopsies etc. before treatment then there's something very very wrong. But said people would not have been scared and didn't have to go through possibly painful follow up checks.

        If screening shows positive, the next step is ultra-sound. If ultra-sound finds something, the next step is a biopsy. If the biospy finds cancer, then treatment starts.

      I, Misogynist(ic wanker)

      Try and understand this concept - false positives just cause worry and stress.

      false negatives cause dead teens and women - including my ex partner who was effectively given a death sentence at 14 because the NHS flat out refused to test her for the cancer she actually had.

      BUT THERE IS NO FSCKING WAY you can spin this criminally negligent incompetence as any form of positive outcome.

      Even had I not lost a partner to cancer and had my own run in with it (a lot less serious thankfully) I'd happily beat your skull in with a claw hammer just for having the gall to write that comment.

      You should be so very happy I'm not responsible for your upcoming prostate exam because it'd involve sandpaper and a dab of jalapeño, and that'd be the fun part of the experience!

        Re: The real question is...

        I fully understand your comments, my wife has had a false NEGATIVE screening in October and repeated false negatives in April, however the surgeon realised that there was something wrong. It turned out that some cancers, even developed cancers do not show up on a screening test. Ultra sound guided biopsies of the right type plus MRI and CTI scans are needed. My wife is now starting her treatment next week.

        Please accept my sympathy over your loss.

        I am not entirely sure about your proposed prostrate investigation plan for the dumb nut. Surely a suitably heated old fashioned toasting fork should be used for both their examination and possible excision of any offending material.

        PS concern was expressed about a possible secondary site in my wife a 'false positive' in wankers nomenclature: a rapidly organised examination showed that the suspect item was not a problem, so treatment can go ahead, in spite of other unconnected existing problems, comorbidities in the jargon.

          Thanks Richard,

          I still really haven't recovered from what happened to her, still so very angry about how badly she was mistreated and abused, and the waste of it all. 10 years this September. I wouldn't trust the NHS as far as Prof. Hawking could throw them.

          I hope your wife recovers well, there are some herbal preparations that can help with nausea but you need to check them with the consultant - a good one for bruising is Arnica which is readily available (reduces bruising in general and after surgery). I think she's very lucky to have found a good consultant who's inclined to do a proper job..

          Ironically I got told for nine MONTHS I didn't have cancer, paid privately, and the dermatologist took less than 3 minutes to refer me to surgery. I've had abuse from my GP surgery for having the affrontery to get a second opinion and to be in charge of my own medication (for what would probably be called a co-morbidity (certainly would be if I went to Saudi)) to the point I changed surgeries and then after the second BCC showed up they cut it out and promptly lost the biopsy accidenteliberately.

          Certain people are about to find they're in the process of being sued.

          To top it all off I get told categorically, by an experienced GP, that BC Carcinoma CANNOT spread - 3 minutes on Google states a 1% metastatic rate - favourites being lung and brain... That GP has at least 25 years experience..

            With all due respect, when you're defending the high moral ground (and you were, very well), it's best not to throw it away like that.

            And, FWIW, my partner works in PHE on screening programmes. Any expectations that people may have about the omniscience of the NHS should be rapidly dispelled. It's an organisation of people, like any other. It's constrained by resources, but even more so by structures, policies and people, and things go wrong. Frequently. And whilst you may be angry, I can assure you that far more than 270 lives have been lost due to imperfections in screening since 2009. At the local level screening is art, at the national level it is statistics. I really wouldn't use the word "science" for screening, certainly until the accuracy of the techniques available are substantially more accurate than they are.

              If that was the only tantique usque gallus the NHS made I might be prepared to agree with you.


              I almost *died* from misprescribed medication and had medication I urgently needed buggered about with by a NHS GP who was nothing to do with my case and caused me and my family 3 years of hassle including contacting consultants behind my back.

              I had hip problems at 13, which misdiagnosed (actually flat feet) have caused me a lifetime of spinal pain to the point I'm off work and have more than once been curled up on the floor in agony.

              I have had important allergy information suspiciously deleted from my records which could have risked my life..

              I've had verbal abuse from GPs and hospital staff - surgeries and treatments denied despite the fact they're mandated..

              I've had bloods taken so badly I ended up seconds from intensive care..

              That's over and above the cancer situations I've detailed and not including working for the NHS in IT which to be blunt was more terrifying than all that put together - scanners being run by BBC Micros, lockdown passwords set by someone who'd since buggered off to Dubai and forgotten to mention what they were, oh and a patch deployment system that was somewhere to the left of guesswork..

              Did I forget to mention being prescribed Fentanyl as I requested (especially on the assumption on my part it was less addictive and safer than morphine - to which I have a family sensitivity (the local NHS effectively murdered my maternal grandmother with it, for her moderate flu, despite it being listed that SHE SHOULD ON NO ACCOUNT TAKE IT, even if Hell was freezing over at that very second)) - no one thought to mention it was up to 25x more addictive than morphine..

              Should I go on?

              True it might be accidental incompetence or misreading or just a single xx-phobic bigoted GP but there's an old military saying. "once is happenstance, twice is coincidence, three times is enemy action". Last I looked I was on somewhere around number seven or eight..

                May I respectfully suggest that requesting Class A, controlled medications should be left to Doctors rather than patients, particularly if you fail to read the warnings or understand that Fent is an opiate that's used to knock out Great Elephants. It's clearly labelled at every junction how addictive it is, as all opiates are.

                Sounds very odd to me that one of the most powerful and addictive controlled drugs were prescribed on request. I take oxycodone regularly and if I walked into any GP and asked for it, morphine or Fent I would be kicked out of the surgery. After the doctors finished laughing. If I'm not in handcuffs.

            Would it count as manslaughter? These people died of natural causes, and were going to anyway. Failing to spot that they needed treatment isn't really manslaughter, otherwise every single death of someone untreated would make a doctor liable.

            It's definitely a bad thing, but surely it's better to spot/treat/screen most people and miss a few than stop anyone trying to do this in the future for fear of litigation?

              Re: So manslaughter is OK

              Technically... Possibly.

              The important part is "were going to anyway".

              If it was a situation where the cancer had already staged and spread *and would have been in that condition* when the screening session was missed then probably it would be impossible to prove that a detection at a late stage and treatment would have resulted in a cure... Therefore you really couldn't argue manslaughter, at best medical negligence.

              However. If the cancer would have been detected before staging or very early I or II (for example in a very aggressive cancer like my partners (although that was also to do with her age)) and there is a reasonable chance that a cure could have been effected if it had been caught in time then manslaughter *could* be argued since, as I understand it, manslaughter means you either accidentally caused or *contributed to* by material actions or in this case inaction the death of the individual concerned - although whether it'd succeed is another matter.

              The problem is that it would be what lawyers call a "technically interesting" case which to quote the great Sam Vimes (I believe) is lawyerese for "$600 a day plus overtime, and it'll take months".

          Emotional damage and stress to all involved.

          I know of someone working giving out some of the screening invites. The "computer bug" they found, thankfully in time to send out late, but valid, invites... was as simple as the training saying "type search for cancer screening*" when it should have been "screening for cancer" and the new system missing the old systems search results due to wording ORDER.

          They felt horrible for the mistake, but in reality, how were they to know the system was setup with 2 different search terms (old and new) and did not bring up a per word result (screening + cancer) but only brought up a single term result ("cancer screening" exactly).

          *not actual term, as I was not working there so don't remember, and to protect identity etc.

            "how were they to know the system was setup with 2 different search terms (old and new) and did not bring up a per word result (screening + cancer) but only brought up a single term result ("cancer screening" exactly)."

            I can only speculate on how *they* could have known, but *I* would have known because the testing would have included identifying records (which could have been artificial test records, or anonymised real records, or perhaps just plain real records with suitable privacy precautions taken) containing one word, and both words, and no words, together and apart, testing search terms in all the various permutations, and the results compared with the expected output based on the identified test records.

            Whether by design or process or procedure or incompetence, what on the face of it sounds like a relatively simple test to consider and execute wasn't done. This is incompetence; spread across which levels (project, programming, testing, management, requirements, etc etc), I couldn't speculate, but this is incompetence.

      Yes you do learn from it. One of the key lessons learnt is that you test boundary conditions. The fact that rudimentary testing didn't spot the error suggests that the design of the algorithm and the testing both matched a specification which had the wrong age limit.

        c) Because one of the daily newspapers said something rude about something tangentially associated with the project

    No, people write computer programs, people provide the training data and managers sign off and release it. Other managers deploy it.

    See also Irish Cervical Cancer screening. Most of the experts told the managers the outsourcing to USA wouldn't work (they were detecting much less in trial), partly because USA screening was designed for annual tests and Irish tests are / were every three years. Most of the experts then resigned.

    It's the managers that are killing people. Manslaughter by deliberate negligence. Not computer algorithms.

      Worse is when blame is placed on an algorithm. Every choice made by an algorithm is decided by some person, usually for a specific reason. When you get screwed over it's because someone decided you should be, not because HAL decided not to open the pod Bay doors.

      All of this leads the general public to think that they're powerless against "computers, " and that problems are caused solely by technology, not by the people who implement it.

      Crikey it all started at age 14, makes me think of my daughters. Not knowing all the story, I assume you were probably not much older when you went through that with her... all my deepest sympathies!!! I do hope you are well surrounded by family and friends etc!

      The removal from certain lists entails removal from other, non-related, lists??? This is of course unacceptable and needs to be fixed! I could not find anything on that, though (found nothing after a quick few g00gle's and am a bit busy right now, will try again later), I would really like to make sure this gets fixed, has it been reported [on] ? This listing issue seems to be one list to rule them all, want out of one, get out of all ...

      As for racism, this seems to be a listing blunder. I'm not implying people making decisions in the UK's health system are never bigots, racists, homophobics, or whatever. But in this case it is much more likely a listing blunder, which, as your story implies, can kill, so we must make sure it gets fixed!

        The situation was nasty - involving hpv and familial abuse and that was by no means the worst of it. My rule of thumb is if you've a body part and it can get cancer - you are NEVER too young to get cancer in it. That's the excuse they gave her - you can't have cancer you're too young.

        If your girls are offered the vaccine I'd suggest they take it. Personally I'd make it mandatory. It took my partner almost a decade to die, some of it stuck in a hospital bed to the point if I showed her pictures of my parents garden or just pictures around the area she'd be in floods of tears.

        Unexplained weight loss, tiredness, back pain, bloating or fainting are signs and if doctors dismiss you get a second, third, fourth opinion..

        In teens you have very very little time to act because the sky high hormone levels overdrive the tumour - so what might take 10-15 years in an adult woman takes 10-15 months in a teenage girl.

        I've had another idea for said commentard involving testicles - pinky mice and my friendly but always hungry Western Hognose snakes. They're generally adorable little snakes that pretend to be rattlesnakes - but don't get between them and food, they're aggressive feeders and they chew a venom into the food which causes swelling in humans... Cue testicles that could have been used at Trafalgar in the 6 pounders (about apple sized) and (from my experience of finger and hand bites) swell up to the hardness of wood... Not that I'm vicious or anything...

        I'm not going to comment on this any more because it's starting to stress me. But just be aware that the symptoms of cancer in teenagers can be diffuse and difficult to pin down, and the No Hope Service are not necessarily your friend in this situation.

      Even if you can prove a person who died from breast cancer (and that'll be fun, as there are myriad ways to die from cancer that don't say "cancer" on the death certificate) you are still left having to show that had they received a call for screening AND they had responded (remember that 29% non attendance) AND the screening had picked up their cancer (remember false negatives) AND that result had triggered a course of treatment (bearing in mind what was available at the time) AND that course of treatment had been successful (because all treatments have a failure rate) THEN you might just be in with a chance.

        Many of the treatments would kill you, while a slow growing cancer wouldn't actually affect you in any way before you die of something age-related.

        More aggressive cancers are an entirely different thing, however those aren't generally found this way - or at least, not early enough to help.

        Check your breasts and your balls. Seriously, do that often.

    Noticing 45K missing invites a year does not require careful code analysis

    I'm guessing that would translate into at least 25K fewer visits per year, which an Accountant should have noticed even if eagle-eyed code reviewers didn't spot anything.

    Is this really the root cause?

    OK, so a faulty algo caused a bad problem. But why was there a faulty algo? Generally it's because of lack of testing. Why is there lack of testing? Generally because of lack of QA resources. And why is there a lack of QA resource? Outsourcing to the cheapest bidder because of some ideological ideals. If you do your IT on the cheap, it's not surprising that things go wrong.

    Hey Jeremy (Hunt)

    Hows about a screening programme for the cancer that kills more people in the UK than any other now...

    Namely, Prostate Cancer.

    No? If No then why not? Men are second class citizens when it comes to NHS cancer screening.

      Re: Hey Jeremy (Hunt)

      it isn't that simple. As someone who lost their dad to prostate cancer and my dads brother had it and his first cousin had it, I'm at a higher risk. I go and get a PSA test done every few years (I'm 47) but they have a high chance of a false positive so they aren't given universally and currently there isn't really any other tests around although work is being done to improve this. Its NOTHING to do with men being second class citizen its purely a medical issue. Nothing to see here move along

    Important correction

    This isn't pedantic, as it should set a lot of people's minds at rest, but this issue specifically affects women under NHS England. The issue didn't affect the "British" NHS and Hunt is not the "British" Health minister. Shona Robison, the Scottish Health Minister, has issued a statement to reassure Scottish patients that the issue does not affect NHS Scotland's systems.

    I realise how this comment could be construed, but please just take it as a correction of some incorrect information.

      Another correction but one of omission rather than error, you can still get a breast screening after you are 70 just you have to ask rather than being automatically invited. (

    Web developers seem all too prone to this

    The amount of websites that have been incorrectly coded to reject credit \ debit cards prior to the end of the month that the card is valid to is astonishing. Many just seem to check against the month number and totally disregard what day of the month it currently is.

    Yep, and about 1730 women between 68 and 71 who had a non-progressive cancer were spared an mastectomy, chemo and RT (which have their own morbidity and mortality, particularly in this age group).

    So don't bring out you hankies yet folks. At a guesstimate, probably fractionally less women died as a result of this "faulty algorithm".

    And yes, I am a surgeon dealing with breast cancer patients (among other things).

      Yep++. And if those 450K women had received their scans then your 1730 women would still have been spared, and you might have added a few more to their number and we could use our hankies for a better kind of crying. I have a horrible suspicion this was a cost cutting exercise and not a software fault (see my post read it here first, folks...)

    "There are a number of linked causes, [including] issues with the systems' IT and how ages are programmed into it," he said.

    I'm struggling to work out how that's anything but vaguely technical, "it's really complicated", speak for a massive bit of incompetence by a programmer, irrespective of what sort of time-scales they were working on.

    When they suddenly had a 70% reduction in people having breast screening tests did no one think to question it?

    Probably not the sort of app where you ship the minimum viable product.

    All theoretical as RIPE wouldn't OK drug treatment as not economically viable for women of that age

    The plan is working then - defund it, watch it break down, people cry "something must be done", hand it to the private sector as the solution.

    I wonder if this was a deliberate act rather than a fault. Trim a few of the edge cases, save a bit of money. There seems a bit of doubt about cancer testing for people at the top of the range and beyond, so they could, at a pinch, moralise about that. And where should the bottom edge be? 59? 61? You could console yourself abstractly about that. And money is saved so they can use that to save more lives immediately. I find it entirely plausible that something like that could happen in a huge bureaucracy, especially one under prolonged pressure from above to drive down costs. If only it wasn't for them meddling kids. Perhaps I'm becoming too cynical.

    What kind of monster calls their child 'Feremy'?

    It's guaranteed to get them a kicking every day of their lives at school, resulting in the kind of twisted psyche capable of "At this stage it is unclear whether any delay in diagnosis would have resulted in any avoidable harm or death"

    It never will be clear; Science isn't whatabouttery - you can't say what would have happened if you had done something else, only what did or (at a pinch) will happen after doing what you did/will do.

    How is a mind capable of that kind of utterance allowed out on even day release, never mind to run a national/governmental service?
