Drafting Acute Kidney Injury Discharge and Follow-Up Letters

The problem

Acute kidney injury (AKI) admissions generate important discharge communication needs. The GP needs to know what happened, what the recovery trajectory was, what medications were changed, and what monitoring is required going forward. The patient needs to understand what happened, what signs of recurrence to watch for, and which medications to avoid.

AKI discharge letters are frequently inadequate in practice — too brief to be useful, or failing to specify the monitoring plan clearly enough for a GP who was not involved in the admission. A patient discharged after an AKI without clear written guidance on nephrotoxin avoidance and monitoring is at higher risk of recurrence.

How AI helps

An AI tool can draft a structured AKI discharge letter from your clinical bullet points. You specify the precipitant, the trajectory, the medication changes, and the ongoing monitoring plan. The tool produces a professional letter covering all the key sections. You check the accuracy and add what is missing.

The tool is also useful for drafting a patient-facing explanation of what happened — in plain language, explaining what AKI is, why it occurred, what to watch for, and which substances to avoid.

A real example

Dr Kwesi is a nephrologist reviewing a 72-year-old man being discharged after a hospital admission with AKI precipitated by dehydration during a gastrointestinal illness, in the context of pre-existing CKD Stage 3a. He recovered well with IV fluids and his creatinine has returned close to baseline. His ACE inhibitor (angiotensin-converting enzyme inhibitor) was held during the admission and is being restarted on discharge.

He opens an AI tool and types:

Draft a discharge letter to a GP following an AKI (acute kidney injury) 
admission.

Use these headings: Reason for Admission, Clinical Course, 
Investigations, Medication Changes, Discharge Plan, Actions for GP.

Clinical details:
- Patient: man, 72, background CKD Stage 3a
- AKI precipitant: dehydration secondary to gastrointestinal illness
- Hospital course: responded well to IV fluid resuscitation, 
  creatinine improving toward baseline over 4 days
- Medication changes: ACE inhibitor held during admission, 
  restarting on discharge (I will add specific drug and dose)
- Discharge creatinine: back to near baseline 
  (I will add specific value)
- Monitoring plan: GP to recheck renal function and electrolytes 
  in 2 weeks
- Sick day rules: patient counselled to hold ACE inhibitor and 
  other nephrotoxic medications during future episodes of 
  vomiting, diarrhoea, or reduced fluid intake, 
  and to seek medical advice early

Do not include specific drug names, doses, or lab values — 
I will add those.

The tool produces a structured letter. Dr Kwesi adds the specific creatinine values, drug names, and doses. He adjusts the sick day rules section to match his unit's standard sick day rules guidance. He adds his contact details. The letter is ready in eight minutes.

Things to watch for

Sick day rules language must match your unit's guidance. Sick day rules for patients with CKD and those on nephrotoxic medications vary between institutions. Replace the tool's general language with your unit's specific sick day rules documentation — or add a link or reference to your unit's patient information.

Medication changes must be verified. Which medications were held, which were restarted, and which were permanently stopped should come from your clinical records. The tool cannot generate this information accurately. Check the medication section against the actual discharge prescription.

The patient-facing explanation is a separate document. If you want a plain-language explanation for the patient as well as a GP letter, draft these separately. The clinical language appropriate for a GP letter is not appropriate for a patient who may have no medical background. Specify the audience clearly in each prompt.

Nephrology follow-up may be needed. For patients with CKD whose kidney function has not returned to baseline, or for patients with an unclear AKI precipitant, nephrology follow-up may be needed. Make this explicit in the discharge plan section — do not leave ambiguity about whether the patient should be seen again in nephrology or managed solely in primary care.

Remember: AI is a helpful assistant, not a clinician. You make the call.
