- Description: Objective: To estimate the burden of hospitalised fall-related injury in community-dwelling older people in Victoria. Methods: We analysed fall-related, person-identifying hospital discharge data and patient-level hospital treatment costs for community-dwelling older people aged 65+ years from Victoria between 1 July 2005 and 30 June 2008, inclusive. Key outcomes of interest were length of stay (LOS)/episode, cumulative LOS (CLOS)/patient and inpatient costs. Results: The burden of hospitalised fall-related injury in community-dwelling older people aged 65+ years in Victoria was 284,781 hospital bed days in 2005-06, rising to 310,031 hospital bed days in 2007-08. Seventy-one per cent of episodes were multiday. One in 15 acute care episodes was a high LOS outlier and 14% of patients had ≥1 episode classified as high LOS outlier. The median CLOS/patient was nine days (interquartile range 2-27). The annual costs of inpatient care, in June 2009 prices, for fall-related injury in community-dwelling people aged 65+ years in Victoria rose from $213 million in 2005-06 to $237 million in 2007-08. The burden of hospitalised fall-related injury in community-dwelling older women, people aged 85+ years and those with comorbidity was considerable. Conclusions: The burden of hospitalised fall-related injury in community-dwelling older people aged 65+ years in Victoria is significantly more than previously projected. Importantly, this study identifies that women, patients with comorbidity and those aged 85+ years account for a considerable proportion of this burden. Implications: A corresponding increase in falls prevention effort is required to ensure that the burden is properly addressed.

- Description: Background: Nearly half to 60% of falls in community-dwelling older people aged 65+ years result in physical injuries and 20%–50% of these require medical attention, including emergency department visit and hospitalisation. Fallers who stay in hospital longer than would be expected based on the primary injury diagnosis create an excess financial burden on the health system and represent a priority target group for fall prevention. Objectives: To identify and characterise high-length-of-stay (HLOS) patients among community-dwelling older people aged 65+ years hospitalised for fall-related injury. Methods: We analysed hospital discharge data from Victoria, Australia, to identify and characterise HLOS patients among community-dwelling older people aged 65+ years hospitalised for fall-related injury. We defined an episode as HLOS if the length of stay (LOS) was more than three times the average LOS for a particular diagnosis-related group. Results: Between 2005/06 and 2007/08 6822 patients (14.2% of the study group of which 73.8% were women) had ≥1 episode classified as HLOS. The HLOS patients accounted for 19.9% of episodes and 39.9% of bed days. HLOS patients were similar to non-HLOS patients in terms of indigenous status, in-hospital mortality and ethnicity. However, HLOS patients were older, less likely to be married, less likely to have hospital insurance and more likely to have comorbidity than non-HLOS patients. Significance/Contribution to the Field: This study identifies priority groups for a targeted prevention approach.

- Description: Background: Studies comparing internally linked (person–identifying) and unlinked (episodes of care) hospital discharge data (HDD) on hip fractures have mainly focused on incidence overestimation by unlinked HDD, but little is known about the impact of overestimation on patient profiles such as comorbidity estimates. In view of the continuing use of unlinked HDD in hip fracture research and the desire to apply research results to hip fracture prevention, we concurrently assessed the accuracy of both incidence and comorbidity estimates derived from unlinked HDD compared to those estimated from internally linked HDD. Methods: We analysed unlinked and internally linked HDD between 01 July 2005 and 30 June 2008, inclusive, from Victoria, Australia to estimate the incidence of hospital admission for fall-related hip fracture in community-dwelling older people aged 65+ years and determine the prevalence of comorbidity in patients. Community-dwelling status was defined as living in private residence, supported residential facilities or special accommodation but not in nursing homes. We defined internally linked HDD as the reference standard and calculated measures of accuracy of fall-related hip fracture incidence by unlinked HDD using standard definitions. The extent to which comorbidity prevalence estimates by unlinked HDD differed from those by the reference standard was assessed in absolute terms. Results: The sensitivity and specificity of a standard approach for estimating fall-related hip fracture incidence using unlinked HDD (i.e. omitting records of in-hospital deaths, inter-hospital transfers and readmissions within 30 days of discharge) were 94.4% and 97.5%, respectively. The standard approach and its variants underestimated the prevalence of some comorbidities and altered their ranking. The use of more stringent selection criteria led to major improvements in all measures of accuracy as well as overall and specific comorbidity estimates. Conclusions: This study strongly supports the use of linked rather than unlinked HDD in injury research. In health systems where linked HDD are unavailable, current approaches for identifying incident hip fractures may be enhanced by incorporating additional evidence-based criteria.
