Archetype authoring attribution

2012-03-23 Thread Sam Heard
Hi David

 

As the aim for all is interoperability of these things, I would hope that
the information would be two way. I would suggest getting the new experts to
comment on CKM and then derive a 13606 archetype (this is described in the
13606 standard). I would like that to be a future part of CKM but understand
this may seem a little too controlling.

 

If we start creating clinical content specifications in lots of places it
will not really assist medicine a great deal. We estimate that it is costing
health care dearly to do this again, again and again. Particularly when
providers are interested in quality and sharing information.

 

That said, I would attribute the work to openEHR, the original authors,
contributors and any new expert inputs. The license is to openEHR so I guess
it is openEHR that needs attributing if you want to stay with the legal
requirement. The SA does mean that you have to share the derived work under
a similar license, something that some have been worried about. I am
interested in your views on this.

 

Cheers, Sam

Hello,

 

Back again with the licensing topic of archetypes, with a real use case.

 

We have been asked to help in creating a set of 13606 archetypes for breast
and prostate cancer. Although they will probably incorporate some new
requirements, the main source will be some of the openEHR archetypes
available at the CKM.

Assuming that the have adopted a CC-BY(-SA) license (I cannot recall which
is the state of that discussion), the doubts are the following:

 

- Converting the archetype to a new reference model is considered as a
derivation? Or the openEHR archetype is considered just as a reference
material as could be any textbook or paper?

- The author of the new archetype has to be the one of the openEHR archetype
(Ian McNicoll btw) or the person who in fact creates the new RM-based
archetype?

 

The underlying question here that should be clarified is to define which is
the extension of the concept derived work.

 

David

if it is the same archetype, then it is a derived work. Which is fine,

Multiple inheritance is easily implemented in Java and C# ... via interfaces.

The problem is that you often need to duplicate code. For example, in that 
diagram, VALUE_CLUSTER inherits from both ELEMENT and CLUSTER. In C# you can't 
do that, so you would probably declare ValueCluster as implementing two 
interfaces, IElement and ICluster; then you would copy the implementations of 
Element and Cluster into ValueCluster. Java would do something similar, 
although the naming convention of the interfaces might be different. (In C#, 
you might even decide to avoid some of the code duplication by using extension 
methods. Or maybe not ... it might cause more trouble than it solves.)

Suggestion to replace use of generics with inheritence in future RM versions

2012-03-23 Thread Grahame Grieve
Generally, you can do things in specifications that can't be
reproduced in actual implementations.
Since there is one specification, but many implementations, the list
of things that the specification
contains that aren't easy to implement varies widely between implementations.
The things that are hard to implement are sometimes also very useful
for expressing meaning
and purpose. So a good specification balances between using things
that are useful without
using things that are too hard to use.

With regard to generics, my normal implementation contexts do not
support generics (XML/XSD, old
versions of various languages), but I still find them useful in the
specifications and would prefer
the specification expressed itself cleanly

Of course, sharing these models is the only way to achieve global
agreements I do not know which kind of changed they would require for the
archetypes (if any) but I think they will be related to the real data
available at the EHR system of the hospital. So they will be probably very
localized changes. What clinicians have done right now is to translate most
of the archetypes into Spanish, and that can be very easily incorporate
into the openEHR CKM archetypes.

 That said, I would attribute the work to openEHR, the original authors,

There is no doubt about the attributions and original references that must
accompany the new archetypes (by the way, maybe in this sense the archetype
metadata could be improved. Diego Bosc? has been working on this topic for
his PhD). The question as I said before is about the authorship attribution
and the meaning of derived work. See below.

 - thomas



Probably the problem is not so simple. I will put different options of
things that can happen as an example  (any new case is welcome):

1- If I take an openEHR archetype and modify/specialize it as a new openEHR
archetype it is a derived work.
2- If I take an openEHR archetype and generate an implementation guide
document of it, it is a derived work. The change of the format does not
affect as you said.
3- If I take an openEHR archetype and generate software, schemas, etc. as
Thomas said in a different thread they are not derivative works, they are
original works based on the specification
4- If I take an openEHR archetype and generate another archetype of a
different reference model based on it (could be 13606, HL7 CDA or
whatever), is this a derivative work? The fact that the openEHR to 13606
conversion is nearly straightforward is not relevant here. It could be not
the case. At the end someone (or some automatic process) will have to
decide the correspondence between different reference models. For me this
is exactly the same case as point 3. Thus, should not be considered a
derivation but a new work which uses the original archetype as a reference,
as could have been any textbook or paper.
5- If I take an openEHR archetype and generate an HL7 CDA implementation
guide based on it, is this a derivative work? The answer to this depends on
the previous one. The fact of representing clinical models in a different
format (if we see ADL just as a format for defining models) should not
change the essence of the problem as we saw in point 2.

See that I'm just trying to set out the limits of the problem to find a
general rule if it is possible.

 and inheritance in an appendix of 
 Bertrand Meyer's Object Oriented Software Construction, 2nd edition. 
 (http://se.ethz.ch/~meyer/??publications/acm/geninh.pdf 
 http://se.ethz.ch/%7Emeyer/publications/acm/geninh.pdf seems to be the 
 original paper that the appendix is based upon.)

 Generics can be simulated in a language with inheritance, but there is a 
 cost:
 * Duplication of code.
 * Extra verbosity.

 I don't want to have either forced upon me. If I'm unfortunately forced to 
 use a language that doesn't support generics, then I can always simulate it 
 the generics with inheritance. But I certainly wouldn't want the specs to 
 be obfuscated by hacks like that, thanks very much ;-)

13606 revisited - list proposal

2012-03-23 Thread Thomas Beale
 
 like a structured series, mainly because ACTIONs usually need to get 
 recorded when they are done.

 IMO ACTION.time:DV_DATE_TIME could have the same semantics as 
 ACTION.data.events[0].time, if ACTION.data:HISTORY and 
 events[0]:POINT_EVENT.

 The easier example is a repetitive INSTRUCTION like give 5mg of XXX 
 for 10h every 30m:

   * The ACTION would register the same information structure
   * The proposed POINT_EVENT of the ACTION could record the
 information like the current ACTION.time attribute
   * There is a series of ACTIONS recorded for the same INSTRUCTION
 (instead of creating one ACTION instance for each XXX
 administration, one ACTION could handle all the information, time
 series and data, for all the susbtance administrations for the
 same INSTRUCTION/ACTIVITY).


 For example, a regular IV drug administration _could_ in theory be 
 represented by an ACTION with a HISTORY, each of whose events 
 described the action (say: admin Morphine 20 mg IV) but to achieve 
 this you would have to wait until all the administrations were done 
 before writing the data. So for some hours it would look like no drugs 
 were being administered, then a long series of them would suddenly 
 appear in the EHR stretching back... days?

 I can't see the difference with the current ACTION model: the ACTION 
 could be created when the administration starts, and the date/time of 
 that event could be written in INTERVAL_EVENT.time attribute, and when 
 the administration ends, the duration could be written in the 
 INTERVAL_EVENT.width.

 Maybe I'm missing something here, but that's whay I understand.

 I am not saying ACTION is perfect - there have been suggestions for 
 example that an ACTION + link + OBSERVATION structure should be 
 available for when the prescribed 'action' was in fact a new 
 observation, such as 'check patient reaction to drug'.

 It would be nice to discuss this proposals with more members of the 
 community. I'm not saying we need to do the changes, what I say is 
 lets discuss if we can improve the model in some way, analize the pros 
 and cons, and write down a decision. I mean: we need to try to not 
 leave these kind of discussions die on the maillist, this things are 
 valuable assets that could be explored/exploted in the future.

 Another question of time comes up with EVALUATION - e.g. the diagnosis 
 archetype. This is full of times, and tries to follow a disease course 
 model. Currently there is no RM class for this, but if a standardised 
 temporal disease model were agreed across medicine, I suppose there is 
 no reason why not. But it also is not a simple HISTORY - it is more 
 'bumpy'... and I don't know if there is any agreed standard model of this.

 Maybe is something like a HISTORYENTRY or a HISTORYCOMPOSITION?


 Thanks a lot for sharing,
 Kind regards,
 Pablo.

Units, Quantities, etc

2012-03-23 Thread Daniel Karlsson
, the question of units is thorny.
  Although we technical people would like to mandate UCUM or some other
  well-designed computable syntax, on its own, it won't work. There seem to 
  be
  two reasons for this:
  
  it doesn't take care of the need for a displayable form of units, e.g. the
  computable form 'mcg' or 'ug', where as the displayable is '?g' (Greek mu
  followed by 'g')
  it doesn't take care of 'units' like puffs, tablets, patches, vials, 
  strips,
  and other discrete delivery units
  it doesn't take care of discrete delivery units per time, e.g. '2 puffs /
  hour'
  
  Grahame and others have already done a lot of thinking on this here - 
  there
  are a lot of excellent examples from Linda Bird on the Singapore 
  programme.
  
  The more I think about the last two above, the more I think it is not 
  about
  quantities per se but about an administration directive (how the patient
  should take something). Trying to make Quantity do that kind of stuff
  doesn't make sense to me - there is obviously a Quantity to indicate the
  dose in scientific form, but another data element may be needed to 
  indicate
  how (in what discrete measures) to take the medication.
  
  I would therefore expect a distinct data element in the Medication Cluster
  archetype rather than a re-engineered Quantity type to deal with these 
  last
  two. For the first one - displayable v computable, we will need a CR to
  change DV_QUANTITY, and make it work like the FHIR Quantity - i.e. have a
  second units field.
  
  Some of my earlier thoughts are actually on the above wiki page - the
  concept of a DiscretisedQuantity type inheriting from Quantity, which I
  think is also a reasonable alternative.
  
  what do others think?
