Clinical continuity and the recovery objective

The question is not how long until systems are restored. It is how long the organization can deliver safe care without them.

Abstract

Clinical continuity and the recovery objective

Summary

In most sectors a recovery time objective is a commercial decision. In healthcare it is a clinical one, and that changes both the number and who is entitled to set it.

This paper argues that recovery planning should be built backwards from clinical downtime tolerance, examines why the restoration sequence must be agreed clinically in advance, and sets out why a rehearsal without clinical participation validates the technology and misses the point.

Key findings

Four things this paper argues

If you read nothing else, read these. The analysis that follows sets out the evidence for each.

01

The recovery objective is a clinical number, not an IT preference

How long the organization can deliver safe care on paper is the constraint. IT should be told the number rather than choose it.

02

The restoration sequence must be agreed clinically before an incident

Not everything restores at once, and deciding the order during an event wastes the hours that matter most.

03

Identity restores first, and this is routinely underestimated

Nothing else can be restored until people can authenticate, and identity recovery is the least rehearsed part of most plans.

04

An IT-only rehearsal validates the technology and misses the point

The exercise that produces useful findings runs the downtime procedures at realistic volume with clinical leadership present.

Analysis

The argument in full

Starting from the clinical procedure

Every provider has downtime procedures — paper forms, manual processes, verbal handover. Most were written years ago, few have been rehearsed recently, and almost none have been tested at the scale a real event would require.

The recovery plan should be built backwards from these. How long can the organization deliver safe care without systems? That number, produced by clinical leadership, sets the recovery objective.

This inverts the usual sequence, in which IT proposes an objective based on what infrastructure can achieve and clinical leadership is asked to accept it. The inversion matters because a technically achievable target that does not match clinical tolerance is the wrong target regardless of how well it is delivered.

The restoration sequence

Not everything can be restored simultaneously, so the order has to be decided in advance and agreed clinically.

Identity first, because nothing else can be restored until people can authenticate — and because identity recovery is consistently the least rehearsed element of a recovery plan. Then the clinical record, and specifically the read-only access path to it. Then scheduling and patient flow, which determine whether the organization can operate at all. Then diagnostics and results routing, where delays translate directly to clinical risk. Then revenue cycle, which matters enormously and is genuinely not first.

Writing this down before an incident converts a series of contested decisions under pressure into an executed plan.

  • Identity and authentication, rehearsed as a distinct step
  • The clinical record, including the read-only access path
  • Scheduling and patient flow
  • Diagnostics and results routing
  • Revenue cycle, which is important and is not first

What the rehearsal has to include

An IT-only recovery exercise validates the technology and misses the point.

The exercise that produces useful findings involves clinical leadership, runs the downtime procedures for a realistic period, and tests whether the paper process works at volume rather than in principle. Every provider we have seen do this properly has found something significant, which is the argument for doing it deliberately rather than discovering it during an event.

The findings are usually not technical. They concern where the downtime forms are stored, whether staff have ever used them, whether a ward can actually operate on paper for the period the plan assumes, and who is authorised to declare an incident. All of these are cheap to fix on a planned Saturday and expensive to discover otherwise.

Framework

Something you can apply without us

Every paper in this series ends with a framework you can run internally. We would rather you used it and reached your own conclusion than took ours on trust.

Framework

Building recovery backwards

Five stages, starting with a clinical question.

1

Ask

Clinical leadership states how long safe care can continue without systems.

2

Sequence

Agree the restoration order clinically, in advance, and write it down.

3

Protect

Immutable backups isolated from the production domain, with identity recovery rehearsed.

4

Rehearse

Run downtime procedures at realistic volume with clinical leadership present.

5

Fix

Assign every finding an owner and a date. A rehearsal without follow-up was a training exercise.

Implications

What this means, depending on your seat

The same argument lands differently across an executive team. These are the three versions worth separating.

For the Chief Medical or Nursing Officer

For the CIO

For the board

We run a coverage and recovery assessment across the estate and facilitate the rehearsal with your clinical and IT leadership together, which is the part that produces the useful findings.
