Can ‘short lists’ facilitate the collection of data on ‘diagnosis’, ‘intervention’ and ‘presenting issue’ in community health and outpatient care services? Casemix 2008, Adelaide, Australia Joe Scuteri & Lisa Fodero
Community health and hospital outpatient services account for a large and growing proportion of the work of the NSW health system.
Little is known about the nature of the services provided, the patients receiving those services, and their ongoing needs and future demands.
Outpatient services increasingly substitute for same day patient services in NSW largely due to funding incentives, resulting in information loss.
New AHCAs will deliver reform “through recognition of the ways in which primary care and acute care interact; introduction of activity-based funding across the country … and strict performance measures”.
Need to capture community health and outpatient care data
Community Health and Outpatient Care Information Project
CHOCIP was developed by the NSW Health Department in response to this rapidly developing service delivery environment.
CHOCIP encompasses the collection of patient level data for hospital outpatient care clinics and publicly funded community health services.
Largest project of its type ever attempted in Australia and when complete will result in the annual collection of some 25 million unit records.
Project began in 2006 with three phases planned
Phase One: Where are we now? Where do we want to be? How do we get there?
Phase Two: Infrastructure development (current phase)
Phase Three: The roll out (expected start date 1 st July 2009)
The project methodology consisted of five major processes:
A range of classification systems were evaluated to assess their suitability as the underlying base for the short lists for the data elements diagnosis, intervention and presenting issue.
Draft short lists were developed for the three data elements for each of the 132 service types (i.e. 396 short lists) by reviewing the literature, conducting initial consultation with clinicians, and collecting and analysing any available (coded) data.
The draft short lists were refined by working with the Clinical Advisory Groups (CAGs) formed specifically to advise on the suitability of the short lists for one or more of the 132 service types (in progress at the time of preparing this paper).
The draft short lists will be pilot tested at 15 to 20 service delivery sites that are representative of community health and outpatient care services in NSW.
The pilot test results will be analysed (including frequency counts of the use of the short list categories) and the short lists will be refined and finalised.
Wide range of classification system already in use in NSW across community health and outpatient services;
care needed to be taken in choosing appropriate classification systems to ensure that existing data sets are protected while the consistency of what is collected in CHOCIP is preserved;
to choose between the leading classification system options, a set of evaluation criteria was formulated against which each option for each data element (diagnosis, intervention and presenting issue) was assessed.
ICD-10-AM (diagnosis and presenting issue) and ACHI (intervention) was one option.
A classification system specifically for community health services had been formulated as part of a major project to develop an enterprise system for community health, the Australian Classification and Terminology of Community Health (CATCH).
Other major candidate was ICPC-2 PLUS (for all data elements), which is primarily used in general practice settings in Australia.
Some in-scope services used CATCH and/or ICD-10-AM and ACHI but no services used ICPC-2 PLUS.
Many intervention categories in CATCH were based on ACHI codes.
There was a strong desire to link admitted patient data to outpatient and community health data for the same journey (e.g. breast cancer) so ICD-10-AM and ACHI were chosen.
Exceptions will be made for some services (eg domestic violence) where it is known that ICD-10-AM and ACHI do not provide a suitable framework.
Classification system evaluation results – community health
The service types classification developed by the NSW Health Department includes seven categories that relate to cardiology services are:
The first draft short lists for the cardiology unit, nfd were prepared by using admitted patient data for non-emergency inpatient admissions for patients with cardiac disease (AR-DRGs F60A to F75C).
These lists were submitted to the cardiology services CAG for review and refinement at a two-hour face-to-face meeting.
The meeting results were analysed to develop second draft short lists, which were circulated to CAG members by email for final review.

Audiology services represent a single service type in the NSW Health classification
12.02: Audiology/Audiometry Unit.
The first draft short lists were developed using an extract of CHIME data.
Unlike cardiology, where only admitted patient could be used, the CHIME data relate to non-admitted patient services.
The first draft short lists were discussed with two practising audiologists resulting in a refined second draft which was submitted to the audiology services CAG for review at a two-hour face-to-face meeting.
The resultant third draft short lists were circulated to CAG members for final review thereby producing the final draft.

The case studies illustrate the nature of the short lists development process as well as the different issues faced for the service types.
For all services, review of the available data assisted in the generation of some of the draft short lists, but the most important process was always refinement of the draft short lists by working directly with the CAGs.
It took considerable work to actively engaged clinicians in the process.
The short lists have been shown to be relevant to each service type, largely because of the homogeneity of patients and services within each service type.
The data resulting from the implementation of the short lists will be extremely valuable in planning, developing and funding community health and outpatient care services in NSW.
The final refinement process will consist of a pilot test of the short lists in 15 services across NSW, covering off at least one service type in each of the 132 categories across community health and outpatient services.
The pilot test will be conducted over a period of six weeks using manual data collection.
Results of the pilot test will be used to refine the short lists which will then be included in the CHOCIP Data Dictionary and enterprise systems.
The results will also be used to decide the nature of the glossary of terms that needs to be developed as well as to shape the maintenance process that is required to keep the short lists consistent with clinical practice.
