The discharge summary is one of the most critical documents in medicine. A poor discharge summary leads to medication errors, missed follow-ups, and patient readmission. A good one ensures seamless continuity of care between hospital and primary care. This guide covers exactly what to include, how to write it efficiently, and the mistakes that harm patients.
Why the Discharge Summary Matters
The discharge summary is often the only document a GP receives after a patient’s hospital admission. Studies consistently show that medication discrepancies in discharge summaries are a leading cause of preventable harm in the post-discharge period — responsible for an estimated 1 in 5 adverse drug events in primary care.
When a patient is readmitted within 30 days, the first thing the emergency team reaches for is the last discharge summary. If it is incomplete, inaccurate, or illegible, clinical decisions in the acute setting are made with insufficient information. The stakes are high.
Components of a Complete Discharge Summary
1. Patient Identification and Dates
Always include: full name, date of birth, NHS/hospital number, date of admission, date of discharge, and the admitting and discharging consultant and team.
2. Admission Diagnosis
State the reason for admission as documented at the time — even if it turned out to be incorrect. This is clinically and medico-legally important. For example: “Admitted with acute onset chest pain, initial diagnosis of possible ACS.”
3. Discharge Diagnosis
The final, confirmed diagnosis or diagnoses at discharge. If multiple problems were addressed, list all relevant ones. Use precise terminology rather than vague phrases. “Confirmed NSTEMI with peak troponin 1.8” rather than “heart problem.”
4. Clinical Course
A concise summary of what happened during the admission: key investigations, their results, procedures performed, clinical response to treatment, and complications if any. This should be narrative but efficient — the GP does not need a day-by-day diary; they need the key decision points.
5. Procedures Performed
List all significant procedures with dates: coronary angiography, joint aspirations, lumbar punctures, surgical procedures, endoscopies, etc.
6. Significant Investigation Results
Include only the clinically significant results — the ones that drove diagnosis or management decisions. Do not transcribe every blood test result. The GP needs to know peak troponin, lowest eGFR, positive microbiology cultures, and imaging findings. They do not need to know that the platelet count was 248.
7. Medications on Discharge — The Most Critical Section
This is the section most likely to cause patient harm if done incorrectly. The medications list must include:
- Every medication the patient is taking on discharge, with dose, frequency, and route
- New medications started during admission (clearly flagged)
- Medications stopped or changed during admission (with reason)
- Duration of any time-limited medications (e.g., “prednisolone reducing course: 40mg OD for 5 days, then 30mg OD for 5 days, then 20mg OD for 5 days…”)
- Any medications requiring monitoring (e.g., “warfarin — target INR 2–3, GP to monitor weekly initially”)
8. Allergies
Always document allergies and the nature of the reaction (anaphylaxis vs. intolerance vs. side effect). Never leave this blank.
9. Follow-up Plan
Specify exactly what follow-up is required:
- Outpatient appointments booked (specialty, timeframe)
- Appointments that need to be arranged by the GP
- Blood tests that need repeating and when
- Imaging that needs repeating or follow-up reporting
- Referrals made and pending
10. Pending Results
Explicitly list any results pending at discharge: microbiology cultures, histopathology, specialist test results. State who is responsible for following these up and what action is required if they are abnormal. “Urine culture pending — if positive, please treat as per sensitivity results. We will contact the patient directly if growth is significant.”
11. Reason for Any Medication Changes
If you stopped a medication that the patient was previously on, explain why. If you changed a dose, state the reason. GPs need this context to make safe prescribing decisions in follow-up.
12. Patient Information and Safety Netting
Document what information was given to the patient about their diagnosis, medications, and what to do if symptoms return. This includes written information leaflets, verbal safety netting, and who to contact in an emergency.
Common Discharge Summary Errors That Harm Patients
Medication errors
The most dangerous category. Includes: omitting medications the patient was taking, failing to flag new or changed medications, incorrect doses, failure to document duration for time-limited drugs, not specifying monitoring requirements for high-risk medications such as anticoagulants, lithium, or steroids.
Missing follow-up
Vague follow-up instructions (“GP to review as appropriate”) are not sufficient for complex patients. Be specific: “6-week cardiology outpatient appointment booked — patient informed. GP to repeat U&E at 1 week due to ACE inhibitor initiation.”
Pending results not flagged
Patients are discharged with culture results, biopsies, or scan reports pending every day. If these are not explicitly flagged with a clear action plan, they fall through the cracks. Never assume someone else is following up.
Incorrect diagnoses
Copying last admission’s diagnosis incorrectly, using wrong laterality, or transcribing lab values inaccurately. Always verify before completing.
Using AI to Write Discharge Summaries Efficiently
One of the most effective applications of AI documentation tools in clinical practice is discharge summary generation. With MedDraftPro’s AI Medical Report Generator, you can enter the key clinical details in bullet-point form and receive a fully structured discharge summary draft in seconds.
The critical step remains clinician review. Go through every section — medications especially — before submitting. AI tools eliminate the blank-page burden and ensure consistent structure; the clinician ensures clinical accuracy.
Timing: When to Write the Discharge Summary
Best practice is to complete the discharge summary at the time of discharge, or ideally earlier if the discharge is planned. Writing it after the patient has left, from memory, days later, leads to gaps and inaccuracies. In many trusts, completing the discharge summary is now a hard stop before the patient can formally be discharged.
Summary
A high-quality discharge summary requires the same clinical rigour as any other aspect of patient care. It is the last clinical act of a hospital admission and the bridge to safe community care. Master its structure, prioritise the medications section above all else, and use AI tools to improve efficiency without compromising accuracy.
