What changes when it is healthcare & hospitals

Most RAG projects fail at retrieval, not generation, the model was fine, the right passage was never fetched. We benchmark retrieval separately, because that is where the accuracy actually lives.

In healthcare & hospitals, clinical safety and patient privacy mean nothing ships without human oversight and a complete audit trail. That single fact reshapes how rag & knowledge retrieval has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is patient triage and follow-up calls, usually integrated against LIS. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

Built by engineers who ship production systems, not by a practice that subcontracts the build. We hand over with runbooks, tests and a team that knows how it works, not a dependency.

RAG & Knowledge Retrieval workloads in healthcare & hospitals

  • discharge summary drafting
  • prior authorisation and insurance paperwork
  • appointment scheduling and reminders
  • clinical coding support
  • patient triage and follow-up calls

What is included

  • Ingestion pipeline for your real document formats
  • Chunking and embedding strategy tuned to your corpus
  • Hybrid keyword plus vector retrieval with reranking
  • Citations on every answer, traceable to the source page
  • Permission-aware retrieval that respects existing access rules
  • Retrieval quality benchmarked against a labelled question set

Questions from this sector

Is patient data safe?

We deploy inside your infrastructure or a compliant cloud region, with de-identification wherever the workload allows it and full access logging. Patient data does not leave the boundary you set.

Will clinicians accept it?

Only if it saves them time on the first day. We start with documentation burden, discharge summaries and notes, because that is the pain clinicians name first.

RAG or fine-tuning?

RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.

How accurate will it be?

We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.

Can it respect our existing permissions?

Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.

RAG & Knowledge Retrieval for healthcare & hospitals, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
