What you need to know

  • Listen carefully to the patient: frank psychotic symptoms (positive or negative) may not be apparent initially—be alert to sub-threshold symptoms such as problems with mood or sleep; alteration in personality, and functional decline

  • Take family concerns seriously and actively seek from them relevant information (or from school or university, as appropriate)

  • Accompaniment by family or carers at appointments can be particularly helpful, but ask your patient whether they also want to be seen alone during the appointment

Identification of psychotic symptoms in non-specialist settings is key to initiating timely pathways to care. A systematic review of 30 observational studies of pathways to care of first-episode psychosis showed that first contact was more usually through a physician than through emergency services.1 This article is aimed at generalists, primary care physicians, and hospital doctors, who play a critical role and who require a low threshold for referral for specialist assessment, sometimes before diagnosis is certain.2

Prompt intervention is key to improving outcome. However, patients rarely present complaining of hallucinations or delusions. Concerns that something is not quite right may first be raised to the generalist by family members, friends, neighbours, and school teachers.1

When to consider emerging psychosis

In very early stages, perceptual abnormalities and thought disorder may not be apparent, nor delusions well formed. Features may include:

  • Sleep disturbance

  • Anxiety, irritability, or depressive features

  • Social withdrawal

  • Unexplained decline in academic or vocational performance3

  • Incoherent or unusual speech

  • New or unusual preoccupation with mystical or religious themes

  • Concerns with hacking through internet or smartphones

Hallmark features are increasing distress and decline in functioning.456

How to approach psychotic symptoms:

An overview of symptoms is shown in figure 2. Psychosis maybe preceded by subtle changes in functioning and gathering intensity of distress. Be wary of dismissing unclear presentations as teenage angst or drug misuse. In the midst of diagnostic uncertainty, primary care providers can build rapport through repeat consultations.

Figure2

Fig 2 Overview of psychotic symptoms

Symptoms of anxiety or depression may precede psychosis and should not be assumed as the definitive diagnosis without prompting further exploration for psychotic symptoms. Positive symptoms may not be volunteered. Be prepared to actively seek out symptoms (see box 1). Sometimes these may only be inferred from behaviour.

Box 1: Specific questions to elicit psychotic symptoms and history

Starting the conversation
  • “It seems that there is quite a lot that is on your mind; I’d like to ask you a bit more about that and in particular about any worrying thoughts you might be having. Is that OK?

Eliciting psychotic symptoms
  • Have you been feeling that people are talking about you, watching you, or giving you a hard time for no reason?

  • Have you been feeling, seeing, or hearing things that others cannot?

  • Have you been spending more time alone?3

Establishing context
  • Have stressful or traumatic experiences affected you recently or in the past?

  • Is there any history in yourself or your family of mental health concerns?

  • Have you used any alcohol or other drugs recently?

Cultural background may also influence the experience of psychosis: in one UK observational study (n=123), Asian patients more commonly attributed psychosis to supernatural experiences than did white or black patients.7

Key features to elicit

  • Seek evidence of positive symptoms:

    • Hallucinations—Identify modality (commonly auditory) and content. Which features differentiate the hallucination from reality (for example, do others share the experience; are the voices attributed to people living at a distance)? Sometimes hallucinations may be suspected by observing the patient in conversation or gesturing or responding emotionally. Ask the patient what they are experiencing.

    • Delusions—Ask the patient about their belief and the basis for it. Is it shared by others or in keeping with cultural and religious norms? Can the patient consider alternative explanations? Are there paranoid, grandiose, or bizarre qualities? Does the patient believe that their thinking or actions are controlled by someone else (passivity)?

    • Thought disturbance—Does conversation with the patient maintain coherence? Does the patient jump from topic to topic (tangential) or veer off course gradually (circumstantial)?

  • Seek evidence of negative symptoms:

    • Alogia (poverty of speech)—Consider whether the conversation flows and whether the patient elaborates on their answers

    • Anhedonia (lack of pleasure in activities)—“Have you lost interest in activities that you used to enjoy before?”89

    • Flattened affect (lack of spontaneity or reactivity of mood)—Does the patient’s facial expressions and communication during the interview feel forced or stilted?

    • Avolition (lack of drive)—“How do you spend your time?”89

    • Social withdrawal—“Have you found yourself turning down any opportunities to go out with your friends? Do you prefer to be with others or your own?”89

  • Consider functional impairments affecting work, home, school, and relationships. Note the social network and history suggesting withdrawal from family and friends.10

  • Risk factors:

    • Ask about family history of mental illness

    • Have adverse experiences occurred in earlier life?

    • Ask about use of alcohol, nicotine, and other drugs. In particular ask about cannabis, given its association with psychosis onset11 and poor outcome1213

    • Are there current stresses?

    • Consider whether pregnancy or recent delivery is contributory (“post-partum psychosis”—for a review, see Florio et al14)

    • Is sleeplessness contributing?

    • A medication history is important—for example, corticosteroids can precipitate psychosis.

  • Assessing insight is important (see box 2). Good insight mediates engagement with treatment and self management, whereas poor insight increases risk of relapse.1617

Box 2: Insight in psychosis*

Insight in psychosis indicates the patient can recognise and accept that their experiences are abnormal and caused by a mental illness.15 It is not an all or nothing phenomena and may change over time. The domains of insight can be assessed by the following questions:

  • Identifying unusual experiences—How do you explain these experiences?

  • Awareness of illness—Do you think you have an illness? Could there be a mental health explanation to this?

  • Willingness to take treatment—Would you agree with taking medication or having therapy?

  • *Adapted from David15

What if the patient does not attend?

Patients may not directly present, and your first clue may come from others, sensing something may be wrong while often struggling to convince their relative to seek help. Families may feel overburdened or unsure where to turn, or the patient may lack an effective advocate. The primary care team is well placed to follow up missed appointments, use text reminders, and maintain contact with the family. If your patient does not attend appointments, consider undertaking a home visit.

It is good practice to obtain the patient’s consent when discussing the situation with carers. However, professional confidentiality is not broken by receiving information. If the patient does not want their history discussed with carers, it can be helpful to explore why—for example, if this is due to paranoid ideation. Even without consent, you can help family members to understand the nature of psychosis and general principles of treatment.

If your patient does agree, try to engage carers. In one large cohort study (n=549), the 10 year risk of unnatural death (including accidents and suicide) was decreased 90% in those with full family involvement at first contact.18

Risk assessment

Risks will depend on the patient, illness and environment. Consider:

  • Risk to self—Around 5% of patients with schizophrenia die from suicide.19 Greatest risk is around initial presentation and shortly after discharge from hospital.20 Ask about suicidal ideation, previous attempts and plans, and self harm. Consider accidental and non-accidental injury. Inquiring about self harm or suicidal ideation does not increase the likelihood of self harm.

  • Risk to others—Be particularly concerned if the patient voices delusional ideation regarding others. Ask about confrontation with others and forensic history. If needed, act promptly to ensure the safety of vulnerable individuals such as children or dependents, considering safeguarding arrangements as appropriate in your local area.

  • Command hallucinations—The presence of command hallucinations should raise concerns. What is being commanded? Is the patient able to not act on the hallucination?

  • Risk of self neglect—This includes nutritional risk (malnutrition, dehydration, Wernicke’s encephalopathy); poor personal hygiene (risk of infections, worsening of chronic medical conditions); and fire risks (does the patient smoke or live in a chaotic home environment?).

When to refer

Refer all cases of suspected psychotic disorder to specialist services.456 Frank psychotic symptoms accompanied by high levels of risk demand urgent action in conjunction with secondary care. Consider whether assessment by the crisis response team or hospital admission is required.

Tests and investigations

If possible undertake initial physical investigations (see box 3). However, no standard battery of baseline tests exists, nor any consensus on whether they should be undertaken in primary or secondary care.21 Against this, in the absence of clear indications of organic pathology (such as head trauma, delirium, seizures), if patients are too unwell or reluctant to have investigations this should not hinder referral and treatment.

Box 3: Baseline investigations

Assessment for organic causes will be guided by the nature of the presentation and usually includes the following.

  • Blood tests:

    • Full blood count

    • Urea and electrolytes

    • Liver and thyroid function tests

    • Urine sampling to rule out illicit drug use

    • If organic differential suspected or neurological features (such as focal neurology or seizures), test for HIV, syphilis (VDRL test), vitamin B12, anti-NMDA receptor antibodies

  • Consider neuroimaging (computed tomography of head or magnetic resonance imaging) particularly if neurological features (somnolence, seizures, recent head trauma) or abnormalities on neurological exam are present

  • Baseline metabolic assessment before starting antipsychotic medication:

    • Body weight and body mass index

    • Waist size

    • Serum cholesterol concentration

    • Fasting plasma glucose concentration

  • Offer a baseline electrocardiogram if the patient:

    • Has a history of cardiac risk

    • Is admitted to hospital

    • Starts certain medications (see Summaries of Product Characteristics of individual drugs5)

What to tell the patient and carers (box 4)

Box 4: How to approach the consultation—What patients and families tell us

  • Adopt a non-judgmental approach through what is said and not said. Listen and understand the patient’s version of reality, however bizarre it may appear, in order to discover more about what is going on in their world

  • Ask focused questions if psychosis is suspected and do not too readily dismiss symptoms as the results of depression, anxiety, or substance misuse

  • Avoid arguing with the patient—for example, by saying, “Of course there aren't devils under the bed.” It works better to say, “I understand that this is how it appears to you, but this is how it appears to me”

  • Be true to the person as they were when well. Remember hostility can be a symptom of the illness

  • Avoid diagnostic labels at too early a stage; instead, focus the discussion around the patient’s symptoms and experiences

  • Avoid using stigmatising language. For example, some patients prefer “a person who experiences schizophrenia” rather than “schizophrenic”

Involve patients and seek their views. Adopt a positive approach, explaining that psychosis is treatable and in many cases can be fully treated without recurrence. Explain your thinking and acknowledge if their view differs. Try to involve carers with the patient’s consent. When referring a patient, explain its purpose and who they are likely to see and when.

Education into practice

  • How might you assess for psychotic symptoms in someone presenting with subtle changes in functioning and increasing distress?

  • Are you aware of what mental health services are available locally for people presenting with symptoms suggestive of psychosis—both for referral and clinical advice and for patients to access if in crisis?

  • What things might you do differently as a result of reading this article?

A patient’s perspective

A few years ago I found that I was experiencing high degrees of anxiety, mainly at work. I went to the doctors at varying times. First I was given an online CBT course, then drowsy anti-histamine tablets, then SSRIs. I decided to stop taking the medication when I heard that I might be on it for life.

Eventually I was finding working in the office so hard that I began working at home. In isolation my health declined further until I could not work, and so I went off on sick leave. I felt drawn to New Age spiritual teachings and living in the moment, but this became an unhealthy obsession which played on my mind.

Eventually I decided to see a doctor who recognised my mental ill health, but I moved back to my parents and so found a new GP at home. But this new GP was slower to identify the problem and I was prescribed anti-anxiety medication. This was partly due to me not disclosing the fullness of my ill health, since I was slow to admit it to myself. The GP did not allow me to claim the medication on the NHS as he thought my illness would only be temporary. This turned out not to be the case.

I was eventually referred to a psychiatrist who recognised my psychosis and prescribed me anti-psychotic medication.
