Summary: The aim is to describe the trends in fall-related hospitalisations for older people living in aged care facilities. Over the 9-year period investigated, there were dramatic increases in fall-related hospitalisations. This worrying trend highlights that we may not be addressing falls in aged care facilities sufficiently. Introduction: The purposes of this study are to describe the trends in fall-related hospitalisations in older people living in aged care facilities and to compare these trends across different demographic groups and injury types. Methods: This study was conducted in Australia's second most populous state, Victoria. Aged care facilities in Australia provide high- and low-level nursing care for people who can no longer live independently. Included in this study were hospital admitted episodes of care which met the following criteria: age 65+ years at admission, an admission source indicating a transfer from an aged care facility, an external cause indicating a fall, a care type of 'acute', a Victorian postcode of residence, and an admission date between July 1, 2003 and June 30, 2012 (inclusive). Rate denominator data were Victorian aged care bed years. Results: Over the last 9 years, 7098 episodes of care met the inclusion criteria. The age-standardised rate of hospitalisation increased by 11 % (95 % confidence interval [CI] 9 %, 12 %) per year. Serious injury increased at a slower pace than less serious injury. The slowest rate increase was for hip fracture (incidence rate ratio: 1.03 (95 % CI 1.00, 1.06), the most common fracture type. Conclusions: Rates of fall-related hospitalisations in older people living in aged care facilities increased at a dramatic pace in the period studied. The relative slower increase in hip fracture may point towards changing referral practices, possible success in osteoporosis management, body mass index increases in older people living in aged care facilities or a combination of these factors.

Summary: In this longitudinal case-control study, acute fracture was associated with low serum testosterone, which was transient in 43 % of men. While assessment of gonadal status is part of the assessment of bone fragility, measurement of testosterone in the early period after fracture may overestimate the prevalence of androgen deficiency. Introduction: Measurement of circulating testosterone is recommended in the evaluation of bone fragility in men. Since acute illness can transiently decrease circulating testosterone, we quantified the association of acute fracture and serum testosterone levels. Methods: A case-control study was conducted involving 240 men with a radiologically confirmed minimal trauma fracture presenting to a tertiary referral hospital and 89 age-matched men without a history of minimal trauma fracture serving as controls. Follow-up testosterone levels 6 months after baseline were available for 98 cases and 27 controls. Results were expressed as the median and interquartile (IQR) range. Results: Compared to controls, cases had lower total testosterone [TT, 7.2 (3.5, 10.8) vs 13.6 (10.9, 17.1) nmol/L, p < 0.001]. The 143 cases treated as inpatients had lower testosterone levels than the 97 cases treated as outpatients [TT 4.7 (2.3, 8.1) vs 10.3 (7.5, 12.7) nmol/L, p < 0.001]. Group differences in calculated free testosterone (cFT) were comparable to the group differences in TT. At follow-up, in 98 cases, median TT increased from 6.5 nmol/L (3.2, 8.5) to 9.6 nmol/L (6.9, 12.0) p < 0.0001, and SHBG remained unchanged. Of cases with low testosterone, 43 % with TT <10 nmol/L and/or cFT <230 pmol/L at presentation were reclassified as androgen sufficient at follow-up. TT was unchanged in the controls. Conclusions: Low testosterone levels in men presenting with an acute fracture may, at least in part, be due to an acute, fracture-associated, stress response. To avoid over diagnosis, evaluation for testosterone deficiency should be deferred until recovery from the acute event. [ABSTRACT FROM AUTHOR]

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., (© 2014 The Authors.

Background: REACH (Realising Education and Access in Collaborative Health) is an initiative of  students of the University of Melbourne to improve access to primary health care services. It is driven by the voluntary commitment of over 120 students and is built upon the principles of collaboration, interprofessionalism and client-centered care. Summary of work: The feasibility of student-led clinics has been demonstrated with the operation of over 100 such clinics in North America. Senior students from Medicine, Physiotherapy, Nursing and Social Work attended a student-run clinics conference in Jacksonville, Florida, USA in 2010. On return, research was conducted to identify a local underserviced community appropriate for a clinic. On review of the literature, it was determined an interprofessional model of care would best serve this community. The student body engaged a local community health service as a project partner. The model of care at the REACH Clinic was developed by senior students from the schools of Medicine, Physiotherapy, Nursing and Social Work and managed by an interconnected student committee structure. The final consultation model involves a triage process and simultaneous consultation by two disciplines. This model of care was successfully implemented during a 4-week pilot period in October 2011., Results: Several issues were identified during the REACH pilot, with dissonance between the at-times competing principles in health care of interprofessionalism, client-centered care and efficient care., Conclusions: An interprofessional model of care was developed and successfully implemented in a 4-week pilot student-run clinic within an established community health service. While providing a free health service, this model facilitated interprofessional learning at both a clinical and management level and highlighted logistical and ideological challenges that served as the basis for further refinement of this model of community service .

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.

Background: Although hospital-acquired hyponatremia is well described, severe community-acquired hyponatremia has been studied less extensively., Aim: To assess characteristics and outcomes of patients admitted with severe hypotonic hyponatremia (SHH) (defined as serum sodium ≤ 120 mmol/L)., Methods: All patients with serum sodium of ≤ 120 mmol/L who were admitted to 2 large teaching hospitals from January 2000 to August 2007 were identified, and data were obtained from medical records. Main outcome measures were incidence of osmotic demyelination and mortality., Results: Two hundred fifty-five patients were admitted who had SHH (female to male ratio 2:1), and the mean age was 72 ± 14 years. The most common etiological factors were thiazide/indapamide diuretics (41%), syndrome of inappropriate antidiuretic hormone secretion (38%), and hypovolemia (24%). Inappropriately rapid correction of serum sodium (> 12 mmol/L over the first 24 hours) occurred in 37 patients (15%), with 4 patients (11%) developing osmotic demyelination. Patients who developed osmotic demyelination were more likely to be younger, abuse alcohol (3 of 4 patients), and have lower serum potassium levels. One patient had a hypoxic-anoxic episode at presentation. The patients also had a mean serum sodium increase in the first 24 and 48 hours of 21 ± 5 mmol/L and 28 ± 8 mmol/L, respectively. None of the patients with osmotic demyelination received hypertonic saline. None of the patients in whom the serum sodium increment was limited to ≤ 12 mmol/L developed osmotic demyelination. Overall, mortality was 10% and was not related to sodium level at presentation., Conclusions: Patients treated with thiazide or indapamide (particularly elderly women) may benefit from monitoring of serum sodium levels. Inappropriately rapid serum sodium correction is associated with osmotic demyelination, particularly in patients with risk factors for this condition. In contrast to what has been reported for hyponatremia in hospitalized patients, severity of hyponatremia on admission did not predict increased mortality in our patient population.

Invasive pneumococcal disease (IPD) notifications are used to monitor IPD vaccination programmes. We conducted sequential deterministic data-linkage between IPD notifications and hospitalization data in Victoria, Australia, in order to determine whether all diagnosed cases were being reported. The proportion of each relevant hospital admission ICD-10-AM code that could be linked to notified cases was calculated. Total and age-specific annual rates were calculated and compared for notified and non-notified cases. Total incidence was estimated using data-linkage results and application of a two-source capture-recapture method. The first 2 years of IPD surveillance in Victoria missed at least one-sixth of laboratory-confirmed IPD cases. Estimated annual IPD rate increased from 9.0 to 10.7/100,000 and rose even higher, to 11.5/100,000, with age-specific rates possibly reaching 90.0/100,000 children aged <2 years, when using capture-recapture. Strategies to improve notification and coding of hospitalized cases of IPD are required.

Objectives: To evaluate the cost-effectiveness of a multidisciplinary wound care team in the nursing home setting from a health system perspective., Methods: Pseudo-randomized pragmatic cluster trial with 20-week follow-up involving 342 uncomplicated leg and pressure ulcers in 176 residents located in 44 high-care nursing homes in Melbourne, Australia in 1999-2000. Twenty-one nursing homes (180 wounds in 94 residents) were assigned to the intervention arm and 23 to the control arm (162 wounds in 82 residents). Residents in the intervention arm received standardized treatment from a wound care team comprising of trained community pharmacists and nurses. Residents in the control arm received usual care., Results: More wounds healed during the trial in the intervention arm than in the control arm (61.7% versus 52.5%, P = 0.07). A Cox regression with shared frailty predicted that the chances of healing increased 73% for intervention wounds [95% confidence interval (CI) 20-150%, P = 0.003]. The mean treatment cost was $A616.4 for intervention and $A977.9 for control patients (P = 0.006). Most cost reduction was obtained from decreases in nursing time and waste disposal. The mean cost saving per wound, adjusted for baseline wound severity and random censoring, was $A277.9 (95% CI $A21.6-$A534.1)., Conclusions: Standardized treatment provided by a multidisciplinary wound care team saved costs and improved chronic wound healing in nursing homes. The main source of saving was in the cost of nursing time in applying traditional dressings and in the cost of their disposal.
