Clinical Officers Council Pre-Internship common mistakes
Clinical Officers Council Pre-Internship · Understand the traps and how to avoid them.
Closing a febrile or acutely ill medical patient on a single label (usually 'malaria' or 'typhoid') - writing the diagnosis and treatment on the clerk sheet without ever listing an alternative, and without ordering the one test that would exclude the dangerous mimic.
High local prevalence plus heavy outpatient queues reward fast pattern-matching; candidates rehearse diagnoses rather than reasoning, so the first plausible label ends the thinking.
What to do instead
Before writing the plan, force three lines: 'Working diagnosis', 'Must-not-miss' (e.g. meningitis, DKA, sepsis, pneumonia), and 'Test that discriminates'. If the discriminating test is unavailable, state the empirical cover and the review time.
Presenting an acute abdomen without documenting groin/scrotal examination in a male, without documenting hernia orifices, and without stating resuscitation orders (NPO, IV access, fluids, group and save, analgesia, consent, surgical review).
Candidates examine what the vignette emphasises and treat the clerking as a description task rather than a management task; the 'hidden' examination and the immediate orders feel optional.
What to do instead
Use a fixed acute-abdomen template that ends with 'exposures examined: hernial orifices, external genitalia, back, PR where indicated' and a resuscitation box completed for every patient before any definitive plan.
Describing a labour case without stating cervical dilatation, station/descent, membrane status, contraction frequency and the time of the last vaginal examination, so that no judgement about progress or obstruction can be made.
Candidates narrate the story chronologically instead of plotting the partograph; they have read about the partograph but never practised extracting its four data points from a case.
What to do instead
Rehearse a structured labour summary: 'At (time) dilatation was X cm, station Y, membranes Z, contractions 1 in N, caput/moulding present.' Then classify progress as normal, slow, or obstructed, and state the action and review interval.
Prescribing drugs or IV fluids for a child without recording the weight, or reusing an adult dose/volume; and assessing a sick child without counting respiratory rate and documenting the danger signs (unable to drink, vomiting everything, convulsions, lethargy, severe chest indrawing).
Weight is often not taken at triage in busy units, and candidates memorised adult regimens more thoroughly than mg/kg calculations; danger signs are recited only when the vignette names them.
What to do instead
Adopt a rule: no weight, no prescription - write weight at the top of the drug chart and calculate each dose aloud in mg/kg with the maximum stated. For every child under five, complete a WHO danger-sign screen and classify as pneumonia/dehydration/malnutrition before planning.
Calculating public health indicators with the wrong denominator - using total population for maternal mortality ratio (should be live births), or using live births for infant mortality rate (should be live births in the same year), and using incidence and prevalence interchangeably.
The formulas are learned as isolated equations without the epidemiological concept, and under exam pressure the familiar-sounding number is substituted into the denominator.
What to do instead
For each rate, write the numerator and denominator in words first ('deaths of children under 1 year ÷ live births in the same year × 1000'), sanity-check the magnitude (a ratio in the hundreds is plausible; one in the tens is not), then compute.
Presenting a fracture or joint injury with only a description of the radiograph and no record of distal pulses, capillary refill, sensation, motor function, or pain out of proportion - and no re-check after reduction or immobilisation.
The X-ray dominates the candidate's attention; neurovascular status feels like a formality and is assumed unchanged rather than tested.
What to do instead
Write a neurovascular box (pulses, CRT, sensation, active movement, compartment pain) before and after every reduction, cast or splint, plus the joint above and below; treat any deterioration as an emergency.
Writing a psychiatric management plan for a depressed or psychotic patient without recording suicidal ideation, previous attempts, current plan/means, risk to others, and the mental state examination.
Candidates focus on diagnosis and drug choice, believing risk assessment is only needed if the patient volunteers it; the vignette rarely says 'he wants to die'.
What to do instead
Make risk a mandatory section of every psychiatric note: ideation, intent, plan, means, prior attempts, protective factors, and the resulting level of observation and safety plan. Screen for an organic cause (thyroid, substance use, infection) in the same note.
Treating a 'red eye' with topical antibiotics without first recording visual acuity, checking for a fixed mid-dilated pupil, ciliary flush, corneal opacity, contact-lens use or penetrating injury - and treating ear discharge without palpating for mastoid tenderness or checking for facial nerve palsy.
Common, 'minor' presentations seduce candidates into a single-diagnosis shortcut, and the red-flag examination is repeated in textbooks but rarely practised as a checklist.
What to do instead
Memorise and verbalise the sight-threatening red flags (reduced acuity, pain, photophobia, proptosis, pupil abnormality, trauma, contact lens) and the mastoid/facial nerve check for ear complaints; escalate any positive flag the same day.
In a collapsed or multiply injured patient, skipping the primary survey and reassessment - going straight to imaging or to a definitive procedure - and giving drugs or shocks without the age/weight-appropriate dose or energy, or without listing reversible causes in an arrest.
The dramatic intervention attracts attention and the ABCDE sequence is recited in theory but abandoned under time pressure; candidates also underestimate how often a patient deteriorates after an intervention.
What to do instead
Structure every answer as 'A–E findings → intervention → immediate reassessment', and add a line for reversible causes (4 Hs and 4 Ts) in any arrest scenario. State the calculated dose/energy and the weight it was based on.
In ethics and law scenarios, taking consent from a relative for a competent adult, disclosing a patient's HIV status or diagnosis to a spouse or employer without addressing consent, or treating a minor or unconscious patient without documenting the best-interests/emergency justification.
Cultural norms about family involvement conflict with the legal default of individual autonomy; candidates answer from habit rather than from the four principles and the statute.
What to do instead
Answer with an explicit framework: does the patient have capacity? Is the decision voluntary and informed? If not, what is the legal basis (emergency necessity, next of kin for a minor, best interests)? Then state what is permitted, what is not, and what you will document - confidentiality is breached only with consent, legal duty, or a public-health justification you can name.
Failing to offer HIV testing and partner notification in a patient with a suggestive presentation, mis-stating the window for post-exposure prophylaxis, or writing an antiretroviral regimen without checking renal function, weight, adherence and interactions.
HIV is treated as a vertical programme topic rather than a routine part of every clinical encounter, and the time-critical numbers (72 hours for PEP, 28-day course, testing intervals) are memorised loosely.
What to do instead
Add 'HIV test offered and result' to every clerking template; memorise the three time-critical figures (PEP start within 72 hours, 28-day course, retest at 6 weeks/3 months) and the first-line regimen with its baseline tests, then state adherence and interaction counselling in the plan.
