We will be sad to say goodbye to you. Thank you for being our chai-t "Grand
Pooh-Bah", you have done an excellent job and we really appreciate all the
meetings you have organised for us.
Are you free for a drink after chai-t on Friday? Would be good for us all to
have some farewell beers with you after your final meeting.
If the meeting ends up at DHHS perhaps we could go to the Coopers Inn nearby
afterwards (282 Exhibition St)?

Subject: [chai-t] February Meeting & Notes from November Meeting
Fellow Chai-Ters - Happy New Year. I'd like to say thanks to everyone who came
along to the meetings last year and especially to our presenters.
The next meeting will be held on Friday 26th February at 3pm. Venue to be
As my final contribution to Chai-T I intend to do a presentation on some
reporting I've developed using Excel Services. If you've got any "show and
tell" items please bring them along - show and tell items include updates on
developments in your health service. If you have any ideas for topics for
discussion please let me know.
As I'm now on long service leave pending retirement it's time for me to hand
over the Grand Pooh-Bah position to someone younger, smarter and better looking
than me so that opens it up to pretty much everyone. If you'd like to put your
hand up let me know. It's not an onerous task to co-ordinate the meetings.
Notes from the November meeting
There were presentations from Austin and Peninsula regarding WIES estimation
processes. The presentation by Dean Athan at Peninsula generated an
interesting discussion as Dean revealed that their coding audits generate
significant additional WIES that pays for the effort involved many times over.
I've attached the Austin presentation provided to me by Ray Robbins who
developed our WIES estimation model that stratifies our activity into groups
then uses a variety of approaches including general linear models. Ray now
believes that a better approach might be to estimate the DRG using roughly the
1. Using available data items at the time of separation for each episode
identify on or more DRGs that the episode might group to and calculate the
probability for each DRG. E.g. episode 123 might have a 50% probability of
falling into DRGx, 30% probability for DRGy and 20% probability of falling into
2. For each of the candidate DRGs calculate the WIES.
3. For each episode calculate an average of the WIES weighted according
to the probability for each DRG.
It would be easier to estimate the DRG for some episodes e.g. elective surgery
where the PPP is known etc. It sounds to me like an approach worth pursuing.
We also had a discussion about the setting of WIES targets and particularly the
calendarization (or phasing as the Finance people like to call it). One of the
challenges I find is that the monthly targets need to be adjusted for
differences in the number of week days and public holidays in each month year
on year. Chris Hamilton from Monash talked about their approach: They've
developed a web page that allows the units to enter their own calendarization
on a per specialty basis. I reckon this is a good approach as the users
obviously have a much better understanding of what will happening in their
See you at the next meeting.
