1.1ED Encounters303NSW and VIC were the only jurisdictions to provide ED encounter data for analysis in this costing study. The data was provided state-wide by NSW with interpreter required as the only CALD patient indicator. Victoria provided ED data for each of the 4 LHNs, with both preferred language and interpreter required available to identify CALD patient encounters. 1.1.1Cost per weighted activity unit comparisons304The weighted activity unit emergency department calculator for 2014/15 was applied to each emergency department presentation in the samples provided. The calculator will produce a higher price weight for the following:
305The purpose of this test is to identify whether CALD patient groups are more expensive after controlling for URG and Indigenous status (as previously discussed, the CALD results presented relate to non-Indigenous CALD patients). 306Overall findingsThe raw cost per weighted activity unit showed that CALD patients in NSW have a lower cost per weighted activity unit than non-CALD patients (-5.2% (PL) and -3.5% (IR)), while CALD patients in VIC have a higher cost per weighted activity unit than non-CALD patients (+12.5% (PL) and +17.1% (IR)). The higher cost per weighted activity unit in Victoria is purely age-driven, due to the under-estimation of costs for elderly patients within the URG classification system for CALD and non-CALD patients. In fact, when comparing CALD cost per weighted activity unit to non-CALD cost per weighted activity unit for patients of the same age group, the CALD cost is lower than the non-CALD cost. 307After standardising for differences in age distribution between CALD and non-CALD, the age-standardised cost per weighted activity unit for CALD patients is lower than the age-standardised cost per weighted activity unit for non-CALD patients in both states, ranging from -11% (NSW-IR) to -2.3% (VIC-IR). 308On the basis of the cost data presented, an adjustment to the NEP model for ED is not supported: in both NSW and VIC, the CALD cost per weighted activity unit is lower than the non-CALD cost per weighted activity unit when the comparison is performed for patients of the same age-group.
311Table 5.2.1.1 Difference in cost between cost per weighted activity unit between CALD and non-CALD groups
328Note: PL – preferred language as CALD indicator; IR – interpreter required as CALD indicator Results were statistically significant for all tests at 95% confidence except for VIC (IR) 1.1.1Encounter costThe following tests used encounter cost data to understand the difference between the costs of treating the CALD patients compared an average patient. A summary of these results is shown in Table 5.2.2.1. Average cost per encounter was mixed between the jurisdictions. NSW indicated lower average costs for CALD patients by up to 4.8%. VIC data however, indicated higher average costs by as much as approximately 12%. The previous weighted activity unit analysis indicates that this effect is largely age-driven. Pathology and imaging costs were analysed to understand whether usage of these services by CALD patients were contributing to any cost differences in ED presentations. CALD patients in NSW had a lower average pathology cost, while CALD patients in VIC had a higher average pathology cost by as much as 5.4%. The difference in imaging costs between CALD patients and an average patient were less pronounced, with marginal variation identified between CALD patients and an average patient. Table 5.2.2.1: Difference in cost per encounter; including pathology and imaging.
Note: PL – preferred language as CALD indicator; IR – interpreter required as CALD indicator. All results were significant at 95% confidence. 1.1.2Encounter length of stay329Analysis was performed on ED encounters to understand the difference in ED duration for CALD and sample site patients. 330In NSW where interpreter requirement indicated CALD patients, encounters were estimated to be 7.5% longer for the URGs sampled (Table 5.2.3.1). This supports a similar finding in the acute setting for length of stay. 331The VIC data supplied for analysis did not contain a field for encounter length or admission and separation times so results for this test are available for NSW ED data only. 332Table 5.2.3.1: Difference in ED length of stay
Note: PL – preferred language as CALD indicator; IR – interpreter required as CALD indicator All results were significant at 95% confidence. 1.1.1Encounter volume333The purpose of this test was to understand proportion of CALD patient encounters relative to overall volume of ED presentations by triage category. 334The analysis showed consistently across the jurisdictions and indicators tested, a higher proportion of CALD patients in Triage 1 URGs (admitted and non-admitted encounters). In VIC, around 8-10% of these Triage 1 URG volumes were made up of CALD patients. 335The data available indicates CALD patients have a higher representation in more urgent encounters, which may be indicative of higher complexities and therefore higher costs.
337These differences are significant and support the finding of acute encounters, that the average CALD patient age was older than that of the sample site. The difference in average age noted in the ED setting is larger in magnitude compared to that of acute encounters. 338Table 5.2.5.1: Difference in average age
