Writing a referral letter

This topic came up in conversation at the practice recently. Disclaimer – I am not the world’s best letter writer, and English was not my favourite topic at school!

This post is perhaps more an opener to think about how you are currently constructing your referrals, and how you can improve on this. Some people take the mail merge literally, and mail merge their last consultation, whereas some people like to write a life story of their patient. I must admit, I have been guilty of both of these in the past.

The most important point when considering referral letters is what are you asking the person on the end of the referral for. This should be the very first sentence of the referral. For example, if you think someone needs surgery then that’s what the referrer needs to know. Plus, you might wish to explain why you think the patient needs the procedure. An example might be “I would be grateful if you would see this 48 year old woman, who has been suffering recurrent episodes of cholecystitis, for consideration of a cholecystectomy”. Thus, the reader knows exactly what you’re thinking, and hopefully what the patient is expecting.

Leading on to the second point – make sure the referral reflects the conversation you had with the patient. If you’ve told the patient you’re referring them for one reason, and the letter makes it sound like it’s for something totally different, it is going to lead to a difficult consultation between the patient and whoever they have been referred to. So keep the story consistent. For example, if there are strict criteria in your area for knee replacements, and you know the patient doesn’t meet them, it is not helpful to tell them you are referring them for this. In reality, you are referring them to a specialist since you’ve exhausted the options, and you need to see if there’s anything available in secondary care that they can try whilst they don’t meet the threshold for replacement. It works in the opposite direction too – why are you referring someone with a hernia to a surgeon, if they don’t want to have surgery? You need to be clear what your patient’s agenda is, and clarify to them what your agenda is when referring.

The above is by far the most important part of writing a referral. The rest is just details, and, in some ways, is shaped by the referral processes local to you. Examples locally are the virtual gastroenterology and neurology clinics. They have been set up to manage the demand for these services locally. The process is simple – you refer to the clinic, they read the letters, they may provide some advice and not see the patient, they may book patients in for investigations first prior to review, or they might see the patient in clinic initially. As such, giving a good history is essential to them making the right decisions. So thats what you need to do. Go back to the days of having to present patients on the post-take ward round, or back in medical school, and present your patient. For example if there is pain – describe the pain. You need to describe the associated symptoms, and the duration of them. You need to include any relevant medical history or medication history. You don’t need to talk about their broken toenail back in 1984! Think about what you’d like to know if you could give patients forms to describe their symptoms in advance of your appointment. Imagine how much easier the consultation may be if you had a nice outline of everything before you saw the patient. (Remember we do have a rough outline as we at least have their medical history, current medications, etc. in front of us)

You don’t want to bore the reader, and you don’t want them to be digging through your letter to make sense of why a patient is being referred. This is why mail merge letters from the relevant consultation are not the most helpful. Your consultation notes are just that – your consultation notes – not you discussing the case with someone else. We often use abbreviations and incomplete sentences, and flit from one part of the history to another. Read the last consultation in the next patient’s notes you open and see if you feel that you know exactly what the writer was thinking, and whether it was an easy read! The other factor here, is a lot of surgeries undertake referral audits, and/or review referrals before they leave the building, which is another reason to make clear why you are making a referral and whether it lives up to peer scrutiny.

Another reason for writing a concise, clear referral is because it helps you. Writing or dictating the referral may prompt you to undertake some further investigation, or ask a few further questions prior to sending the referral off. I like to write my referral as soon as I have wound up the consultation, where possible, as all of the information is fresh in my mind, and I just find it a lot quicker.

Remember I said you don’t need to tell the patient’s life story? You really don’t! I know this because I have, once or twice, received a response thanking me for my ‘comprehensive’ history. Which I am pretty certain means they stopped reading it halfway through! Just give the relevant points!

I hope this is of use when you write your next referral!

Hypertension – the diagnosis

I’m covering this as it’s a common reason for consulting in primary care. What do you do when you pick up a high blood pressure as part of an examination for another presenting complaint? The answer should not be ‘ignore it and hope it goes away’!

As always, you can read the NICE guidance for all the ins and outs of hypertension diagnosis and management. What I’m going to do is give you some tips on what might be helpful during a consultation where someone has a raised blood pressure but no diagnosis of hypertension.

What I will say (and I can imagine this will become a familiar phrase) is that it is not easy to complete all of this in one 10 minute consultation. So it’s worth planning how to tackle this over a couple of consultations.

Most importantly, you need to know what raised blood pressure is. Here are the definitions to guide you:

  • Stage 1 Hypertension – clinic BP 140/90mmHg or higher AND subsequent 24h BP or home monitoring BP 135/85mmHg or higher
  • Stage 2 Hypertension – clinic BP 160/100mmHg or higher AND subsequent 24h BP or home monitoring BP 150/95mmHg or higher
  • Severe Hypertension – clinic systolic BP 180mmHg or higher OR clinic diastolic BP 110mmHg or higher

I think it’s fair to consider their reason for attendance, and whether this may be impacting upon their BP reading. The other important point is that your patient should be relaxed and quiet whilst the measurement is being taken. It’s a good time for you to complete your documentation. It can be hard to convince a patient to sit and say nothing! Also – make sure you’re using the correct cuff size – this really does impact upon the measurement.

If the BP is high on the first reading then measure it on the other arm also. You should have at least two measurements of BP if the initial one is >140/90. You may take a third if there is a significant difference between the first two. Document the lowest reading taken.

Your first consultation is likely to go as follows if you note a raised BP:

  • You will need to organise 24 hour (ambulatory – ABPM) BP monitoring OR home BP monitoring (HBPM). You might want to discuss these options with your patient. The ideal is ABPM.
  • You can also introduce the idea of hypertension and the lifestyle factors that might impact upon the patient’s BP. It gives them a bit of information to digest in the meantime, and it may allow them to consider how they can alter their lifestyle to make improvements.
  • You can also organise further investigations required to assess for target organ damage (kidneys, heart, eyes), and perform a cardiovascular risk assessment:
    • Bloods – renal function, lipids, HbA1c, liver function (if considering statin)
    • ECG – look for LVH, and REALLY helpful to have a baseline ECG
    • Urine – for albumin: creatinine ratio
    • Fundoscopy – you can look yourself but signposting them to an optician for a detailed check is helpful.
  • To complete a CVD risk assessment (a Q-risk in our case) we will need some information regarding family history of CVD, their height and weight (to calculate BMI), their smoking status, and checking their pulse for AF (which should ideally have been done prior to BP measurement since it can affect electronic BP recording)

You can see that after you’ve taken a history and reached the point of diagnosing a raised blood pressure (which may not have been their reason for attendance) there is quite a lot of explanation and planning to get on with! Don’t forget to address their actual reason for attendance if it wasn’t related to blood pressure.

NOTE – If you diagnose someone with severe hypertension, you need to consider starting an anti-hypertensive there and then. You should probably get on and get some bloods taken on the day to facilitate appropriate monitoring of the medications you have started (e.g. unless you have a recent renal function it is good to get one taken prior to starting an ACE inhibitor, since we need to monitor renal function after initiating said medication). You must also consider referral for same day specialist input if they have signs of papilloedema and/or retinal haemorrhage, or if they have symptoms to suggest an underlying cause e.g. phaeochromocytoma, or referral for investigation if this is possibly secondary hypertension.

The follow-up consultation is hopefully going to be straightforward if you have completed all of the above.

You are going to have the BP monitoring results and be able to diagnose hypertension, and which stage. You will also have the investigation results. This, in turn, allows you to manage the condition appropriately.

What are the lifestyle measures patients’ can take to reduce blood pressure? Did they have a think about these after the last consultation? Are there any changes they think they can realistically make?

  • Diet and exercise (including reducing salt intake, and reducing caffeine intake)
  • Quitting smoking
  • Reducing alcohol intake
  • Relaxation therapies

Who are we giving drug treatment to?

  • Stage 1 hypertension and < 80 years old with:
    • target organ damage
    • established CVD
    • 10-year CVD risk > 20%
    • Diabetes
    • Renal impairment
  • All stage 2 hypertension

Consider referral if < 40 years old with stage 1 hypertension and nil other risk factors, since CVD risk may be underestimated in this population. We need to be looking for a secondary cause in these individuals and offering detailed assessment.

Hypertension should be monitored through clinic readings (unless they have white coat hypertension, in which case home monitoring can be used).

Target BP in clinic is <140/90 if <80 years old or <150/90 if 80 year or older. (home monitoring is <135/85 for < 80years and <145/85 if 80 years or older).

I’m going to stop here.

Do you know which antihypertensives should be used in which groups?

Do you know the stepwise treatment for hypertension?

Do you know how different drugs should be monitored, and what common side effects you might experience with the different medications?

Contraception – the basics

This is one of the most common tutorial topics. Why? Because there’s so much to know, it’s a common reason for women consulting, and it’s something that we don’t spend much time thinking about during our hospital jobs – even Obstetrics and Gynaecology posts!

It’s daunting because there are so many options, and so many situations. Who can have what, and when? What are the side effects? How should it be used?

I am not going to talk about all the methods in-depth here. I thought I would start with a quick overview of the options available, and a fact or two about each to get us started. My knowledge is derived from the Faculty of Sexual and Reproductive Healthcare (FSRH) guidance and the online learning modules that comprise the DFSRH.

One thing I like to do when learning is relate clinical knowledge back to anatomy and physiology. I find that by doing this, things just make sense, and tend to stick in my mind better. So you might notice that this post relates back to the physiology of the menstrual cycle!

So what’s available?

Barrier Methods:

  • Male or female condoms
  • Diaphragms
  • Caps

I’m not going to discuss barrier methods any further!

Combined Hormonal Contraception (CHC):

  • Pills
  • Patch
  • Ring

Progesterone only methods:

  • Pills
  • Injection
  • Implant
  • IUS

Non- hormonal:

  • Copper IUD

You can see why it’s so confusing for both the patient, and the doctor! Within these methods – there are so many brands!

But who are the main players, where hormones are concerned, in the reproductive cycle?

Well we need FSH and LH release from the pituitary gland. These hormones are working on the ovaries to ensure maturation of oocytes occurs over the cycle, and to facilitate the release of one each month. As this is occurring there are changes occurring within the uterus to prepare for potential implantation, and subsequent pregnancy.

Feedback cycle

Why is it useful to know this physiology? Because it lets us work out how the different contraceptions might be working to prevent pregnancy, and how they may impact upon the woman’s bleeding patterns.

The cycle - a rough guide!

Thus, progesterone within combined hormonal contraception (CHC) impacts upon the feedback cycle of these hormones to eventually prevent the mid-cycle LH surge, along with it’s affects on cervical mucus. Oestrogen within CHC is acting upon the endometrium, and preventing follicular development.

Progesterone only methods are slightly more complex, because it depends a little on the specific progesterone, and how it’s given, as to how exactly it affects the cycle:

  • The injection suppresses ovulation
  • The progesterone only pill’s (POP) main action is via effects on cervical mucus, but may or may not suppress ovulation (desogestrel, found in brands such as Cerazette and Cerelle, suppresses ovulation in approximately 97% of cycles)
  • The implant often suppresses ovulation but this is not absolute, and certainly not towards the end of the 3 years.
  • Progesterone emergency contraception prevents the LH surge thus arresting follicular development and delaying ovulation
  • The IUS (e.g. Mirena) has it’s greatest effects on the endometrium and thickening of cervical mucus. It inhibits proliferation of the endometrium, thus making it thin and atrophic.

The Copper IUD, as a non-hormonal method, works by producing a foreign body reaction. It can also affect endometrial enzymes, and copper has a direct toxic effect on sperm and ova. It’s primary mechanism of action is the prevention of fertilisation. However, it can be used as an emergency contraception to prevent implantation.

With perfect use, all methods of hormonal contraception are very effective at preventing pregnancy. However, methods that require patient action (pills and the injection) tend to have higher pregnancy rates, and greater discrepancy in typical versus perfect use. The most effective method at preventing pregnancy is the implant. The Mirena IUS and the implant have a greater impact upon pregnancy prevention that female sterilisation.

That was an initial introduction to contraception. It gives you an idea of whats out there, how they work and how they link into the physiology of the menstrual cycle.

There is much more to know, in order to allow women to make informed choices, and help us consider what might be right, and safe, for the woman.

Let me know if you have any thoughts on the above – and through your comments give me an idea of where we should move on to next within the subject of contraception.
