Tips for GP trainees working in psychiatry
• Treat the patients with dignity at all times. You will never regret it.• Try not to be afraid of psychiatry or psychiatric patients, you cannot
catch madness.• The psychiatric multidisciplinary team is less hierarchical than a
standard medical team – respect this. Recognising the skills and knowledge of the multidisciplinary team will enhance your ability to care for your patients.
• Most psychiatric units are very different from hospital wards. Remember that many psychiatric nurses are not trained or experienced in spotting medical problems and you should not expect them to… that's your job.
![Page 107: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/107.jpg)
• Know how neuroleptic malignant syndrome presents and how to manage it.• Attend a breakaway training course that shows you physical techniques to remove
yourself from violent encounters. Hopefully you will never have to use the skills, but you'll never regret having them, even when you have finished psychiatry and doing other jobs.
• Direct confrontation and shouting at agitated patients rarely calms the situation or leads to a favourable result. Always try to de-escalate tense situations. Offer oral medication before resorting to the intramuscular route.
• Always write up rapid tranquilisation on the ‘as required’ section of the patient's drug chart on all admissions. Write oral and intramuscular routes separately and remember that some drugs (for example, haloperidol) have different 24-hour maximum doses for oral and intramuscular routes.
• Check if a patient has been prescribed antipsychotics before.
![Page 108: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/108.jpg)
• Become fluent in the performance and recording of the mental state examination, you'll be doing a lot of it! Take a crib sheet with the headings on for the first few oncalls and clinics till it becomes second nature (as it will).
• Take drug charts and all admission forms to A&E when oncall in case you need to admit a patient. That way you can take care of all the paperwork at once.
• Make sure you know which consultant is oncall and their contact details. Find this out at the start
of the shift rather than out-of-hours when you need to speak to them urgently.
![Page 109: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/109.jpg)
• Initially you should be discussing all patients you see with a psychiatry consultant.
• Always do a risk assessment. Always ask about suicidal ideation, thoughts of self-harm and thoughts of harm towards others. Other domains of risk include vulnerability from others, self-neglect and psychosis. Remember that not all risks are predictable.
• If you ever think you need to call the consultant, do. But before you do, formulate the patient using the biopsychosocial precipitating/ predisposing/maintaining matrix. Be clear what the main areas of
risk are, and how likely you think they are to happen.
![Page 110: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/110.jpg)
• Learn the process, and become familiar with the paperwork of detaining patients under section 5:2 of the Mental Health Act. When you need to do this you don't want to be learning on the job and paperwork errors cause great headaches for the entire trust.
• Try to de-escalate situations before resorting to the Mental Health Act. If patients feel they have been listened to they can often be persuaded to stay informally.
• Think about any child protection issues.
![Page 111: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/111.jpg)
• Get in the habit of taking a personal alarm with you. Know how to use it. Know how to provide assistance to others who need it.
• Do not get involved in restraint unless you have proper training. Without it, restraint is very dangerous for the patient (and for you).
• People with personality disorders can be difficult to manage. They can bring up polarised feelings within you, and between your team (technically known as splitting). Try and get some exposure to the STEPPS programme for
borderline personality disorder.
![Page 112: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/112.jpg)
• Learn some cognitive behavioural therapy (CBT). If you can't attend a course get some teaching from your team psychologist. GPs pay good money to go on courses to get this experience! Make sure this training finds its way onto your CV.
• Listen to the nurses! They spend much much longer with the patients than you do and have a wealth of knowledge and experience that they are usually happy to share.
• Try to do some home visits with the community psychiatric nurses if appropriate.
• Let it be known that you are interested in seeing some mental health assessments performed by the consultants. This will give you insight into the process which will be useful when you are a GP.
![Page 113: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/113.jpg)
• Learn how to manage the core psychiatric diagnoses such as depression, schizophrenia, and bipolar disorder.
• Get a good chart to guide you when changing patients medications.• Try to become familiar with the side-effect profile of common or significant
psychotropic medications such as lithium, clozapine, the antipsychotics, and antidepressants.
• Learn to spot extrapyramidal side effects. Always write up procycladine ‘as required’
for patients who are on antipsychotics.
![Page 114: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/114.jpg)
• The Maudsley Guidelines are a fantastic resource.1
• Don't let your physical medicine slip – some psychiatrists have been out of the general hospital for long enough to feel deskilled in managing physical (that is, non-mental health) problems. Your team will often be looking for your leadership in this area.
• Remember to consider organic causes of psychiatric presentations.• Mental health stigma and prejudice is real and widespread. Make sure you are not
part of the problem.• Treating people with alcohol issues is difficult. Accept that until they become
motivated, you won't cure them.
![Page 115: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/115.jpg)
• Make sure you laugh. Psychiatry is emotionally demanding and without this release you will really struggle.
• Attend the Balint group, engage with the Balint group, write about the Balint group in your eportfolio (educational supervisors love it!).
• Always do a physical exam and blood tests when admitting a patient unless they really are too agitated. Try not to leave it to someone else to do the next day. It would be awful to miss a medical problem that could result in significant harm to the patient.
![Page 116: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/116.jpg)
• Regardless of your placement try to sit in on or get experience of Child and Adolescent Mental Health Services, Working Age Mental Health Services and Older People's Mental Health Services, liaison psychiatry, eating disorder services, and any other specialist clinics that you think will be useful or interesting.
• Remember that disinhibited older patients with dementia can be the population most prone to assaulting staff.
![Page 117: Terminology in psychiatry](https://reader035.vdocuments.site/reader035/viewer/2022062311/58ed22401a28ab73038b45bf/html5/thumbnails/117.jpg)
• When starting patients on SSRIs warn them that anxiety can get worse in the initial period. Also warn them that positive effects generally take at least 2 weeks and often a month to kick in.
• 1mg lorazepam = 5–10mg diazepam.2
• Always warn patients benzodiazepines are addictive (and antidepressents aren't).• Make your consultant's secretary your best friend. Make tea, offer biscuits, make them want to work for you.
