Grouped and Ungrouped Sub and Non-Acute

Activity

Unpacking the differences

Why is this important now?

After 2014/15 Independent Hospital Pricing Authority (IHPA) will not price ungrouped SNAP activity

Out of scope for C’wealth ABF

42 % of expenditure in NSW ABF Facilities

Overview

•  What is Sub and Non Acute Care?

•  What does “grouped” and “ungrouped” mean?

•  Analysis of the differences

•  What next?

Sub and Non Acute care

l  Specialised multidisciplinary care

l  Functioning and quality of life.

l  Care needs and cost not explained by Diagnosis

What does grouped and ungrouped mean?

l  SNAP Class = Grouped

l  NO SNAP Class = Ungrouped

How did we get here?

1993

•  1996-1997 SNAP Costing and Classification Development Study

How did we get here?

•  1993 AHMAC casemix development plan

1996 1999

•  NSW- 1999 SNAP in “designated units”

2000 2011/2012

•  NHRA

•  NSW Interim Funding Model

•  NSW- SNAP in

“designated services”

How did we get here?

•  AN-SNAP version 2

•  NSW- SNAP in “designated units”

2007

•  AROC

•  PCOC

•  NSW- SNAP in “designated units”

2013 2014 2015

•  IHPA – “Care type per diems will not continue”

•  All NSW SNAP Activity is grouped

•  Further development of RVU’s

•  Meaningful Clinical data available for all SNAP activity

Where are we now, where do we want to go?

•  NSW- SNAP for all sub and non acute activity

Grouped Ungrouped

Question?

l  Are the ungrouped patients more similar to acute than sub-acute?

CLINICAL PRESENTATION

What DRG is that?

l  Are grouped and ungrouped episodes coming from the same pool of patients?

l  Analysis of the DRG assigned to the acute episode preceding either the grouped or ungrouped SNAP episode

The Way Forward

l  Ongoing analysis to inform classification development

l  Use cost data to identify areas of priority

l  Target clinicians and policy makers to ensure data is understood
