Return of Documentation Patterns
Some months ago now I posted on the idea of creating patterns for EMRs akin to the work that others have done in User Interface design and other areas, all based on Christopher Alexander’s work. We are close to embarking on attempting to build some specific documentation patterns now at the Health Authority. Not the full blown vision with breadth and depth of Alexandrian patterns, but specific, fairly uniform sections of reusable electronic clinical documentation.
These are sitting somewhere in between openEHR archetypes and templates in terms of scope and size. The hope and plan is that these can be designed in a way that they will form the building blocks for the various e-Forms in the multiple clinical information systems, increasing interoperability and care standardization while decreasing rethink for common items. Each pattern will be designed to be a clinical cluster of content that is part of a reusable assessment.
These documentation patterns can managed by a central group (in this case the CARB – Clinical Architecture Review Board) and used, with simpler guidelines, by documentation teams in each application design team. Request for new patterns would come back to the CARB so they can be reviewed and ensure that they are consistent.
Some example patterns include:
- Problem List
- Past Medical History
- Allergies
- Glasgow Coma Scale
- Vital Signs
Some patterns will likely have multiple versions. This could be for a few reasons: evolution of the pattern or there are needs to have different levels of detail in different settings. Patterns evolve over time with improved design: initial design included minimal structure, now it should be more structured and we know how better to structure it. Patterns in different context may need more or less information. Vital Signs is a good example of this – vitals in an ambulatory clinic are much simpler than they are in the ICU. Still the information that does overlap should be the same (e.g. weight, BP, etc). These would be multiple versions of the pattern. Neurovitals will likely be a separate pattern to complement vital signs.
We are early days now, just starting to ramp up the necessary clinical and informatics skills to do this work. The two daunting aspects are: can we crack the clinical content into a sufficient number of truly reusable patterns to make this useful? (and related) how are we going to standardize clinical documentation across a large region that is actively using multiple documentation standards (including many ‘local’ standards) across several care settings and professions.
