Sentinel event nil funding applies to the whole episode, not just the event cost. The Direction says “nil funding for a public hospital episode including a sentinel event.” This means that if a patient is admitted for hip replacement (which costs $20,000 under activity based funding) but suffers a retained swab (a sentinel event), the entire episode receives zero funding. The hospital loses revenue not just for the complication cost but for all the necessary care provided. This is a disproportionate penalty that could exceed the cost of the complication itself. Hospitals may react by trying to code the sentinel event as a HAC instead, which carries a less severe penalty.
HAC lists can change without notice. ACSQHC “develop[s] and amend[s] from time to time” the national list. This means IHPA’s funding model must be updated each time the list changes. Hospitals must track these updates or risk being penalised for a new HAC they did not anticipate. The Direction does not require a transition period for list amendments.
Risk adjustment may be inadequate. The design principles say changes “should not compromise state system financial sustainability.” But if risk adjustment is poor, hospitals that treat high risk populations will be penalised more, potentially leading to avoidance behaviour. The Direction acknowledges the need for refinement but does not guarantee that the final model will be risk adjusted properly. The shadow period is meant to identify problems, but the timeline (report due Nov 2017, implement July 2018) is tight.
State audit expectations are vague. The Direction requires IHPA to “have regard to” the intention that states audit medical records and coding. This does not impose a binding obligation on states to conduct audits. If states drag their feet, the data quality for HAC reporting will remain poor, and reduced funding will be based on inaccurate coding. IHPA cannot force states to audit; it can only encourage.
Definition of avoidable hospital readmission is provisional. The Direction says ACSQHC will develop a list of clinical conditions with condition specific timeframes. Until that list is published, no funding adjustments are made. But the Direction does not set a deadline for ACSQHC. This part of the direction could languish. Meanwhile, hospitals may not invest in reducing readmissions because they face no financial penalty yet.
The phrase “nil funding” may be interpreted differently for block funded hospitals. Block funded hospitals receive a lump sum for a range of services. How does IHPA apply nil funding to a single episode within a block funding arrangement? The Direction says “applying to all relevant episodes of care … in hospitals where services are funded on an activity basis and hospitals where services are block funded.” The application to block funded hospitals is ambiguous; IHPA will need to devise a method for adjusting block grants retrospectively, which adds administrative complexity.
No grandfathering for existing complications. The Direction applies to sentinel events occurring on or after 1 July 2017. For HACs, reduced funding applies from 1 July 2018 after the shadow period. There is no phase in for hospitals that already have high complication rates due to case mix. A hospital that provides risky procedures like cardiothoracic surgery will face penalties immediately, while a hospital that does only low risk procedures will not. The risk adjustment may partially address this, but it is not guaranteed.
The consultation obligation for readmissions does not require IHPA to adopt any particular model. Item 1(i)(c) says IHPA is to “undertake further public consultation to inform a future pricing and funding approach.” This is essentially a research project. No timeline is given. The COAG Health Council intentions (Item 2(iii)) say IHPA must provide additional advice on feasibility and financial implications, but again no implementation date. This part of the direction may produce little binding change.
The direction may conflict with other Commonwealth quality initiatives. The design principles say reforms should “complement existing national and state measures.” But nil funding for sentinel events could discourage truthful reporting. The hospital has a perverse incentive to code the event as something else (e.g., a HAC) to avoid zero funding. This could undermine the accuracy of national sentinel event data, which is used for benchmarking and safety monitoring.
