NHS update on recording patient sex and gender identity

You seem oddly over invested in this issue. Do you have a trans relative?

You are conflating a lot of different things here.

No one is arguing that clinicians should be misled or that patients should receive treatment based on false information. The question is whether there should be a mandate for birth sex to be routinely and universally displayed across all clinical encounters - whether that is proportionate, justified and the impact of such a rule on the privacy of trans patients.

Nor does recording a person's gender necessarily amount to "false information". In many healthcare interactions, a person's gender is the more relevant demographic characteristic, while birth sex is a separate piece of clinical information that may or may not be relevant depending on the context.

The debate is about how healthcare systems should record and disclose different types of information—not about whether clinicians should be deceived.

If clinical decisions about test results from samples are made only reference to the information on the label then sex on sample labels would be needed. (I suspect decisions are not in fact made only by reference to the label.)

Yes, I imagine that M/F is automatically printed out as part of the identifier for a particular patient (name/dob/nhs or hospital number/sex). The sex will be taken into account, if applicable, when the clinician reviews the results and will be downloaded from the notes (not the sample bottle, which is long gone).

Both should be free to make those decisions for themselves as adults with legal capacity who have a right to make decisions about disclosure and access to personal information and decisions about their own healthcare.

You have a right to refuse healthcare. You don't have the right to demand it or request it on the basis of false information that you provide. You don't have the "right" knowingly to decieve a healthcare provider into giving you incorrect and possibly harmful treatment for your sex. It's unfair to the person treating you, as much as anything else.

I'm struggling with how this plays out in practice. Telephone call... Voice often sounds like natal sex. Visually, very few would pass. If you can neither see nor hear the patient, you have to know the sex to make a sound clinical assessment.

This whole thread was started with the OP declaring what was in the best interests of trans people, and I waded in to object to that for reasons clearly outlined in my initial posts.
There are two trans people on this thread: one who would like a birth sex marker on his medical record and the other who would not. Both should be free to make those decisions for themselves as adults with legal capacity who have a right to make decisions about disclosure and access to personal information and decisions about their own healthcare.

The evidence base on how to interpret these values in trans patients receiving gender-affirming hormone treatment is poor

Is there any need to read past that sentence? Using uncertain evidence about endocrinology is a very weak reason to record either birth sex or hormone-treatment sex as a primary reference.

"The evidence base on how to interpret these values in trans patients receiving gender-affirming hormone treatment is poor, but we suggest that
the use of the assigned sex at birth is most appropriate, with the exception of haematocrit as that is testosterone sensitive, so a male refence range
should be used in those treated with testosterone."

Agreed.

Not all tests necessarily follow this pattern of course, but there's is plenty of evidence that some often do. The point is that the picture is complex and mixed and it's not always evidence which marker is more relevant - that entirely depends on the clinical context.

The reason birth sex is sensitive information for trans people is that it can reveal that they are trans.

This is the root of the problem. I think it's unreasonable for society to indulge the idea that being trans is shameful or something to be sensitive about. I don't think society can afford to do so. If we give up the idea that someone's trans status can reasonably be expected to be kept secret then pretty much all problems go away.

That's very interesting. There was a recent trans Reddit thread (with photographs) where a trans person was showing how they had covered up their sex marker on their wristband with a bit of tape. Perhaps not all hospitals are following that standard?

I'm am not trans. Birth sex isn't typically sensitive data for people who aren't trans. The reason birth sex is sensitive information for trans people is that it can reveal that they are trans.

So you are not trans but arguing on behalf of trans people? If so why are you ignoring the lived experience of a trans person who thinks like every other sensible person that sex absolutely needs to be on your medical record.

You seem over invested in this issue. Do you have a trans relative?

I think both. If someone has been taking wrong sex hormones it may mess with results. Would also possibly apply to women on HRT. I'd assume results that aren't what expected would warrant further investigation. Whether the results are wrong because of disease or hormones.

Nope

no one changes sex

the relevant baseline will remain that of your sex

Ooh! Citations and summaries of specfic examples please!

Because that sounds like wishful thinking. I'd have thought that baseline data would either be the same as their birth sex or specific to people of that sex who've been on hormones for a long time, and only rarely the same baseline as the other sex.

But I'm always happy to learn better from people with the facts at their fingertips.

Never happened to me. I was on testosterone for 15 years, and none of the many levels that kept getting checked ever strayed out of the female range.

Except one, of course: testosterone in the blood.

Nor did my endocrinologist, who is a specialist in trans care too, ever inform me that should I be checked for this or that, I needed to inform the practitioner that I was trans because my levels could be in the male range. That never came up.

There should be four identifiers: Forename, Surname, Date of Birth, NHS number.

Most Trusts will also include a hospital number unique to that Trust.

For trans people who are on hormonal therapies (and have been for 6-12 months), the relevant baseline data may well be that related to their gender and not their birth sex.

I have no problem revealing my birth sex with clinicians, people on the internet or anyone else. It's on my medical records, and assumed based on my appearance, name etc in almost every encounter in my life. I'm am not trans. Birth sex isn't typically sensitive data for people who aren't trans. The reason birth sex is sensitive information for trans people is that it can reveal that they are trans.

Well, from what I've seen and experienced, you ultimately only have two broad options as a trans person: be sensible or be paranoid.

If you're sensible, pretty much anything can be smoothed over quickly and efficiently. You spend most of your life being comfortable in your presentation around people. People can focus on their job around you. You can be relaxed in new situations.

If you're paranoid, molehills become mountains. You second-guess everything people say and do, looking for reasons to be hurt. People have to walk on eggshells around you all the time. You stress in advance before every single new situation.

I've seen people in both camps. I never saw the point of even trying the second one, and went straight to the first. I've never regretted it.

“So, in a not fun twist to the tale ending, and despite everything the NHS has put in place to prevent this exact situation from happening, this is how things have ended up anyway.
I’ve been allocated an identity, a ‘gender’ — one that I haven’t actually agreed with I may add — and my sex has vanished.
Is your medical record like mine? Sex erased, gender identity assigned instead?The only way to find out is to submit your own subject access request as I did. But my prediction is that you’ll find something similar on your own record. You may well have been allocated a ladybrain or a manbrain on your medical record, and your biological sex may be missing.

Given the explicit directions and warnings of possible catastrophes by the architects of the NHS data system, it is astounding to learn those clear directions have gone unheeded.
“The term ‘Gender’ is now considered too ambiguous to be desirable or safe”
I think the NHS should probably urgently consider that whilst their sex and gender design guidance was exemplary, their execution of it has failed, horribly, and that failure is now exposing patients to actual, physical risk.
The NHS have monumentally screwed up here. There are very real risks to having patient medical records that do not capture sex, but which instead log only purported masculine or feminine feelings, changeable at will, or at the careless keystroke of an administrative assistant or busy healthcare professional. And a field which can be altered and edited easily is a field which exposes a patient to risk. Should sex be easily editable? No, it should be cast-iron locked down, and it should be the field used for every significant clinical application. And it should be sex, not gender that is the measure used to analyse patient outcomes for diseases, treatments. And it should be sex, not gender, that is the characteristic used to segregate wards for privacy.
Should sex ever be unpopulated? Categorically, NO.
Gender, for those — and ONLY for those — that wish to have their feelings noted on their medical records, should remain the preserve of polite honorifics and pronouns in correspondence. Administrative communication purposes. Not medical treatment, not national screening programmes, not data analysis of medical outcomes and treatment.”

That all sounds, dare I say it, sensible? You recognise that it's a genuine mishap and move on. They apologise for the inadvertent slip, much as someone who was called 'Mr' might say 'actually, it's Dr...'

Exactly, and that’s what’s happened in practice, see the work of Anne Harper-Wright that I linked below. The sex field isn’t populated, instead, every woman in the country has essentially been assigned a lady brain.
