RESUMEN
OBJECTIVE: To assess the impact of the Health Care Homes (HCH) primary health care initiative on quality of care and patient outcomes. DESIGN, SETTING: Quasi-experimental, matched cohort study; analysis of general practice data extracts and linked administrative data from ten Australian primary health networks, 1 October 2017 - 30 June 2021. PARTICIPANTS: People with chronic health conditions (practice data extracts: 9811; linked administrative data: 10 682) enrolled in the HCH 1 October 2017 - 30 June 2019; comparison groups of patients receiving usual care (1:1 propensity score-matched). INTERVENTION: Participants were involved in shared care planning, provided enhanced access to team care, and encouraged to seek chronic condition care at the HCH practice where they were enrolled. Participating practices received bundled payments based on clinical risk tier. MAIN OUTCOME MEASURES: Access to care, processes of care, diabetes-related outcomes, hospital service use, risk of death. RESULTS: During the first twelve months after enrolment, the mean numbers of general practitioner encounters (rate ratio, 1.14; 95% confidence interval [CI], 1.11-1.17) and Medicare Benefits Schedule claims for allied health services (rate ratio, 1.28; 95% CI, 1.24-1.33) were higher for the HCH than the usual care group. Annual influenza vaccinations (relative risk, 1.20; 95% CI, 1.17-1.22) and measurements of blood pressure (relative risk, 1.09; 95% CI, 1.08-1.11), blood lipids (relative risk, 1.19; 95% CI, 1.16-1.21), glycated haemoglobin (relative risk, 1.06; 95% CI, 1.03-1.08), and kidney function (relative risk, 1.13; 95% CI, 1.11-1.15) were more likely in the HCH than the usual care group during the twelve months after enrolment. Similar rate ratios and relative risks applied in the second year. The numbers of emergency department presentations (rate ratio, 1.09; 95% CI, 1.02-1.18) and emergency admissions (rate ratio, 1.13; 95% CI, 1.04-1.22) were higher for the HCH group during the first year; other differences in hospital use were not statistically significant. Differences in glycaemic and blood pressure control in people with diabetes in the second year were not statistically significant. By 30 June 2021, 689 people in the HCH group (6.5%) and 646 in the usual care group (6.1%) had died (hazard ratio, 1.07; 95% CI, 0.96-1.20). CONCLUSIONS: The HCH program was associated with greater access to care and improved processes of care for people with chronic diseases, but not changes in diabetes-related outcomes, most measures of hospital use, or risk of death.

The association between socioeconomic status (SES) and alcohol-related diseases has been widely explored. Less is known, however, on whether the association of moderate drinking with all-cause mortality is modified by educational level (EL). Using harmonized data from 16 cohorts in the MORGAM Project (N = 142,066) the association of pattern of alcohol intake with hazard of all-cause mortality across EL (lower = primary-school; middle = secondary-school; higher = university/college degree) was assessed using multivariable Cox-regression and spline curves. A total of 16,695 deaths occurred in 11.8 years (median). In comparison with life-long abstainers, participants drinking 0.1-10 g/d of ethanol had 13% (HR = 0.87; 95%CI: 0.74-1.02), 11% (HR = 0.89; 0.84-0.95) and 5% (HR = 0.95; 0.89-1.02) lower rate of death in higher, middle and lower EL, respectively. Conversely, drinkers > 20 g/d had 1% (HR = 1.01; 0.82-1.25), 10% (HR = 1.10; 1.02-1.19) and 17% (HR = 1.17; 1.09-1.26) higher rate of death. The association of alcohol consumption with all-cause mortality was nonlinear, with a different J-shape by EL levels. It was consistent across both sexes and in various approaches of measuring alcohol consumption, including combining quantity and frequency and it was more evident when the beverage of preference was wine. We observed that drinking in moderation (≤ 10 g/d) is associated with lower mortality rate more evidently in individuals with higher EL than in people with lower EL, while heavy drinking is associated with higher mortality rate more evidently in individuals with lower EL than in people with higher EL, suggesting that advice on reducing alcohol intake should especially target individuals of low EL.

Changes in cell phenotype are thought to occur through the expression of groups of co-regulated genes within topologically associated domains (TADs). In this paper, we allocate genes expressed within the myometrium of the human uterus during the onset of term labour into TADs. Transformation of the myometrial cells of the uterus into a contractile phenotype during term human labour is the result of a complex interaction of different epigenomic and genomic layers. Recent work suggests that the transcription factor (TF) RELA lies at the top of this regulatory network. Using deep RNA sequencing (RNAseq) analysis of myometrial samples (n = 16) obtained at term from women undergoing caesarean section prior to or after the onset of labour, we have identified evidence for how other gene expression regulatory elements interact with TFs in the labour phenotype transition. Gene set enrichment analysis of our RNAseq data identified three modules of enriched genes (M1, M2 and M3), which in gene ontology studies are linked to matrix degradation, smooth muscle and immune gene signatures, respectively. These genes were predominantly located within chromosomal TADs suggesting co-regulation of expression. Our transcriptomic analysis also identified significant differences in the expression of long non-coding RNAs (lncRNA), microRNAs (miRNA) and TFs that were predicted to target genes within the TADs. Additionally, network analysis revealed 15 new lncRNA (MCM3AP-AS1, TUG1, MIR29B2CHG, HCG18, LINC00963, KCNQ1OT1, NEAT1, HELLPAR, SNHG16, NUTM2B-AS1, MALAT1, PSMA3-AS1, GABPB1-AS1, NORAD and NKILA) and 4 miRNA (mir-145, mir-223, mir-let-7a and mir-132) as top gene hubs with three TFs (NFKB1, RELA and ESR1) as master regulators. Together, these factors are likely to be involved in co-regulatory networks driving a myometrial transformation to generate an estrogen-sensitive phenotype. We conclude that lncRNA and miRNA targeting the estrogen receptor 1 and nuclear factor kappa B pathways play a key role in the initiation of human labour. For the first time, we perform an integrative analysis to present a multi-level genomic signature made of mRNA, non-coding RNA and TFs in the myometrium for spontaneous term labour.

PURPOSE: ICU strain (low number of available beds) may be associated with a delay and altered threshold for ICU admission and adverse patient outcomes. We aimed to investigate the impact of ICU strain on hospital mortality in critically ill patients admitted from wards across Australia and New Zealand. MATERIALS AND METHODS: Ward patient admitted to ICU and ICU bed data at 137 hospitals were accessed between January 2013 and December 2016. ICU strain was classified as low (≤0.5 patients admitted per available ICU bed in a 6-h block), medium (0.5 to ≤1) or high (>1). Logistic regression models were used to examine the relationship between ICU strain and hospital mortality. RESULTS: 57,844 ICU admissions were analysed, with the majority (64.4%) admitted to medium-strain ICUs. Those admitted to high-strain ICUs spent longer in hospital prior to ICU than medium-strain or low-strain ICUs. After adjusting for confounders those admitted to high-strain ICUs [OR 1.24 (95%CI 1.14-1.35)] or medium-strain ICUs [OR 1.18 (95%CI 1.09-1.27)], (p < 0.001) had a higher risk of death compared low-strain ICUs. CONCLUSION: ICU strain is associated with longer times in hospital prior to ICU admission and was associated with increased risk of death in patients admitted from ward.

AIM: To test the association of alcohol consumption with total and cause-specific mortality risk. DESIGN: Prospective observational multi-centre population-based study. SETTING: Sixteen cohorts (15 from Europe) in the MOnica Risk, Genetics, Archiving and Monograph (MORGAM) Project. PARTICIPANTS: A total of 142 960 individuals (mean age 50 ± 13 years, 53.9% men). MEASUREMENTS: Average alcohol intake by food frequency questionnaire, total and cause-specific mortality. FINDINGS: In comparison with life-time abstainers, consumption of alcohol less than 10 g/day was associated with an average 11% [95% confidence interval (CI) = 7-14%] reduction in the risk of total mortality, while intake > 20 g/day was associated with a 13% (95% CI = 7-20%) increase in the risk of total mortality. Comparable findings were observed for cardiovascular (CV) deaths. With regard to cancer, drinking up to 10 g/day was not associated with either mortality risk reduction or increase, while alcohol intake > 20 g/day was associated with a 22% (95% CI = 10-35%) increased risk of mortality. The association of alcohol with fatal outcomes was similar in men and women, differed somewhat between countries and was more apparent in individuals preferring wine, suggesting that benefits may not be due to ethanol but other ingredients. Mediation analysis showed that high-density lipoprotein cholesterol explained 2.9 and 18.7% of the association between low alcohol intake and total as well as CV mortality, respectively. CONCLUSIONS: In comparison with life-time abstainers, consuming less than one drink per day (nadir at 5 g/day) was associated with a reduced risk of total, cardiovascular and other causes mortality, except cancer. Intake of more than two drinks per day was associated with an increased risk of total, cardiovascular and especially cancer mortality.

OBJECTIVE: To determine the glycemic impact of dietary fat alone consumed without prandial insulin in individuals with T1D. RESEARCH DESIGN AND METHODS: Thirty participants with T1D (aged 8-18 years) consumed a test drink with either 20 g glucose or 1, 13, 26, 39, 51 g of fat with negligible carbohydrate/protein on 6 consecutive evenings, in a randomized order without insulin. Continuous glucose monitoring was used to measure glucose levels for 8 h postprandially. Primary outcome was mean glycemic excursion at each 30 min interval for each test condition. Generalized linear mixed models with a random effect for people with diabetes were used to test for an increase in blood glucose excursion with increasing quantity of fat. RESULTS: Glycemic excursions after 20 g glucose were higher than after fat drinks over the first 2 h (p < 0.05). Glycemic excursion for the fat drinks demonstrated a dose response, statistically significant from 4 h (p = 0.026), such that increasing loads of fat caused a proportionally larger increase in glycemic excursion, remaining statistically significant until 8 h (p < 0.05). Overall, for every 10 g fat added to the drink, glucose concentrations rose by a mean of 0.28 mmol L-1 from 330 min (95% CI 0.15 to 0.39, p < 0.001). CONCLUSIONS: Fat ingested without other macronutrients increases glucose excursions from 4 to 8 h after ingestion, in a dose dependent manner. These observations may impact on insulin dosing for high-fat foods in individuals with T1D.

BACKGROUND: Although post-traumatic stress disorder (PTSD) often co-occurs with depression and alcohol use disorder (AUD), treatment settings may not screen for PTSD symptoms. AIMS: To explore the effects of PTSD symptoms in participants seeking treatment for depression and alcohol misuse by capitalising on the DAISI (Depression and Alcohol Integrated and Single focussed Interventions) project. METHODS: Participants (N = 220) with current depressive symptoms and alcohol misuse were recruited from the DAISI project, a randomised controlled trial with four treatment arms. PTSD symptoms were assessed at baseline by the Posttraumatic Stress Diagnostic Scale and again at the 3-month assessment. RESULTS: McNemars t-test assessed for changes in PTSD symptom severity and PTSD symptom clusters at the 3-month assessment. Repeated measures multivariate analysis of variance assessed for changes in PTSD symptoms, by DAISI treatment allocation. At the 3-month assessment, participants with PTSD reported significant reductions in PTSD symptoms (except intrusion) and a lower rate of PTSD, and responded better to integrated depression-alcohol misuse CBT than to the alcohol/depression single-focussed or brief interventions. CONCLUSION: Integrated depression and alcohol misuse CBT may be effective for PTSD symptoms, but intrusions may need to be addressed specifically.

BACKGROUND: The implementation of evidence-based protocols for stroke management in the emergency department (ED) for the appropriate triage, administration of tissue plasminogen activator to eligible patients, management of fever, hyperglycaemia and swallowing, and prompt transfer to a stroke unit were evaluated in an Australian cluster-randomised trial (T3 trial) conducted at 26 emergency departments. There was no reduction in 90-day death or dependency nor improved processes of ED care. We conducted an a priori planned process influential factors that impacted upon protocol uptake. METHODS: Qualitative face-to-face interviews were conducted with purposively selected ED and stroke clinicians from two high- and two low-performing intervention sites about their views on factors that influenced protocol uptake. All Trial State Co-ordinators (n = 3) who supported the implementation at the 13 intervention sites were also interviewed. Data were analysed thematically using normalisation process theory as a sensitising framework to understand key findings, and compared and contrasted between interviewee groups. RESULTS: Twenty-five ED and stroke clinicians, and three Trial State Co-ordinators were interviewed. Three major themes represented key influences on evidence uptake: (i) Readiness to change: reflected strategies to mobilise and engage clinical teams to foster cognitive participation and collective action; (ii) Fidelity to the protocols: reflected that beliefs about the evidence underpinning the protocols impeded the development of a shared understanding about the applicability of the protocols in the ED context (coherence); and (iii) Boundaries of care: reflected that appraisal (reflexive monitoring) by ED and stroke teams about their respective boundaries of clinical practice impeded uptake of the protocols. CONCLUSIONS: Despite initial high 'buy-in' from clinicians, a theoretically informed and comprehensive implementation strategy was unable to overcome system and clinician level barriers. Initiatives to drive change and integrate protocols rested largely with senior nurses who had to overcome contextual factors that fell outside their control, including low medical engagement, beliefs about the supporting evidence and perceptions of professional boundaries. To maximise uptake of evidence and adherence to intervention fidelity in complex clinical settings such as ED cost-effective strategies are needed to overcome these barriers.

Objective The aim of this study was to estimate the difference between treatment costs in acute care settings and the level of funding public hospitals would receive under the activity-based funding model. Methods Patients aged ≥16 years who had sustained an incident traumatic spinal cord injury (TSCI) between June 2013 and June 2016 in New South Wales were included in the study. Patients were identified from record-linked health data. Costs were estimated using two approaches: (1) using District Network Return (DNR) data; and (2) based on national weighted activity units (NWAU) assigned to activity-based funding activity. The funding gap in acute care treatment costs for TSCI patients was determined as the difference in cost estimates between the two approaches. Results Over the study period, 534 patients sustained an acute incident TSCI, accounting for 811 acute care hospital separations within index episodes. The total acute care treatment cost was estimated at A$40.5 million and A$29.9 million using the DNR- and NWAU-based methods respectively. The funding gap in total costs was greatest for the specialist spinal cord injury unit (SCIU) colocated with a major trauma service (MTS), at A$4.4 million over the study period. Conclusions The findings of this study suggest a substantial gap in funding for resource-intensive patients with TSCI in specialist hospitals under current DRG-based funding methods. What is known about the topic? DRG-based funding methods underestimate the treatment costs at the hospital level for patients with complex resource-intensive needs. This underestimation of true direct costs can lead to under-resourcing of those hospitals providing specialist services. What does this paper add? This study provides evidence of a difference between true direct costs in acute care settings and the level of funding hospitals would receive if funded according to the National Efficient Price and NWAU for patients with TSCI. The findings provide evidence of a shortfall in the casemix funding to public hospitals under the activity-based funding for resource-intensive care, such as patients with TSCI. Specifically, depending on the classification system, the principal referral hospitals, the SCIU colocated with an MTS and stand-alone SCIU were underfunded, whereas other non-specialist hospitals were overfunded for the acute care treatment of patients with TSCI. What are the implications for practitioners? Although health care financing mechanisms may vary internationally, the results of this study are applicable to other hospital payment systems based on diagnosis-related groups that describe patients of similar clinical characteristics and resource use. Such evidence is believed to be useful in understanding the adequacy of hospital payments and informing payment reform efforts. These findings may have service redesign policy implications and provide evidence for additional loadings for specialist hospitals treating low-volume, resource-intensive patients.

OBJECTIVE: To describe uptake of hospital in the home (HIH) by major Australian hospitals and the characteristics of patients and their HIH admissions; to assess change in HIH admission numbers relative to total hospital activity. DESIGN: Descriptive, retrospective study of HIH activity, analysing previously collected census data for all multi-day hospital inpatient admissions to included hospitals during the period 1 January 2011 - 31 December 2017. SETTING, PARTICIPANTS: Nineteen principal referrer hospital members of the Health Roundtable in Australia. MAIN OUTCOME MEASURES: HIH admissions by diagnosis-related group (DRG); patient and admission characteristics. RESULTS: 80 167 of 2 185 421 admissions to the 19 hospitals included HIH care, or 3.7% (95% CI, 3.6-3.7%) of all admissions. Median length of stay for admissions including HIH (7.3 days; IQR, 3.1-14 days) was longer than that for those that did not (2.7 days; IQR, 1.6-5.1 days). For HIH admissions, the proportion of men was higher (54.4% v 45.9%), the proportion of patients who died in hospital was lower (0.3% v 1.4%), and re-admission within 28 days was less frequent (2.3% v 3.6%). The 50 DRGs with greatest HIH activity encompassed 65 811 HIH admissions (82.1%), or 8.4% (95% CI, 8.4-8.5%) of all admissions in these DRGs. HIH admission numbers grew more rapidly than non-HIH admissions, but the difference was not statistically significant. CONCLUSIONS: HIH care is most frequently provided to patients requiring hospital treatment related to infections, venous thromboembolism, or post-surgical care. Its use could be expanded in clinical areas where it is currently used, and extended to others where it is not. HIH activity is growing. It should be systematically monitored and reported to allow better overview of its use and outcomes.

BACKGROUND: Cardiac surgery results in complications for some patients that lead to a longer hospital stay and higher costs. This study identified the presurgery characteristics of patients that were associated with the cost of their hospital stay and estimated how much of that cost could be attributed to a bleeding event, defined as requiring 3 units or more of packed red blood cells or returning to the operating room for bleeding. We also identified the presurgery characteristics that were associated with the bleeding event. METHODS: This prospective cohort of patients (n = 1459) underwent cardiac surgery at 3 tertiary referral hospitals in Australia during 2014 and 2015. Clinical data included the variables held by the Australian and New Zealand Society of Cardiac and Thoracic Surgeons registry. Cost data were collected as part of a state-level hospital data collection. RESULTS: Many of the baseline patient characteristics were associated with the total cost of cardiac surgery. After adjusting for these characteristics, the cost of cardiac surgery was 1.76 (confidence interval, 1.64-1.90) times higher for patients who had a bleeding event (P < .001), thus resulting in a median increase in costs (in Australian dollars) of $33,338 (confidence interval, $21,943-$38,415). Several baseline characteristics were strongly associated with a bleeding event. CONCLUSIONS: The impact of a bleeding event on the cost of cardiac surgery is substantial. This study identified a set of risk factors for bleeding that could be used to identify patients for discussion at the heart team level, where measures to minimize the risk of transfusion may be initiated.

BACKGROUND: The National Surgical Quality Improvement Program (NSQIP) is widely used in North America for benchmarking. In 2015, NSQIP was introduced to four New South Wales public hospitals. The aim of this study is to investigate the agreement between NSQIP and administrative data in the Australian setting; to compare the performance of models derived from each data set to predict 30-day outcomes. METHODS: The NSQIP and administrative data variables were mapped to select variables available in both data sets where coding may be influenced by interpretation of the clinical information. These were compared for agreement. Logistic regression models were fitted to estimate the probability of adverse outcomes within 30 days. Models derived from NSQIP and administrative data were compared by receiver operating characteristic curve analysis. RESULTS: A total of 2240 procedures over 21 months had matching records. Functional status demonstrated poor agreement (kappa 0.02): administrative data recorded only one (1%) patient with partial- or total-dependence as recorded by NSQIP data. The American Society of Anesthesiologists class demonstrated excellent agreement (kappa 0.91). Other perioperative variables demonstrated poor to fair agreement (kappa 0.12-0.61). Predictive model based on NSQIP data was excellent at predicting mortality but was less accurate for complications and readmissions. The NSQIP model was better in predicting mortality and complications (receiver operating characteristic curve 0.93 versus 0.87; P = 0.029 and 0.71 versus 0.64; P = 0.027). CONCLUSIONS: There is poor agreement between NSQIP data and administrative data. Predictive models associated with NSQIP data were more accurate at predicting surgical outcomes than those from administrative data. To drive quality improvement in surgery, high-quality clinical data are required and we believe that NSQIP fulfils this function.

OBJECTIVE: To determine whether routine blood glucose assessment of patients admitted to hospital from emergency departments (EDs) results in higher rates of new diagnoses of diabetes and documentation of follow-up plans. DESIGN, SETTING: Cluster randomised trial in 18 New South Wales public district and tertiary hospitals, 31 May 2011 - 31 December 2012; outcomes follow-up to 31 March 2016. PARTICIPANTS: Patients aged 18 years or more admitted to hospital from EDs. INTERVENTION: Routine blood glucose assessment at control and intervention hospitals; automatic requests for glycated haemoglobin (HbA1c ) assessment and notification of diabetes services about patients at intervention hospitals with blood glucose levels of 14 mmol/L or more. MAIN OUTCOME MEASURE: New diagnoses of diabetes and documented follow-up plans for patients with admission blood glucose levels of 14 mmol/L or more. RESULTS: Blood glucose was measured in 133 837 patients admitted to hospital from an ED. The numbers of new diabetes diagnoses with documented follow-up plans for patients with blood glucose levels of 14 mmol/L or more were similar in intervention (83/506 patients, 16%) and control hospitals (73/278, 26%; adjusted odds ratio [aOR], 0.83; 95% CI 0.42-1.7; P = 0.61), as were new diabetes diagnoses with or without plans (intervention, 157/506, 31%; control, 86/278, 31%; aOR, 1.51; 95% CI, 0.83-2.80; P = 0.18). 30-day re-admission (31% v 22%; aOR, 1.34; 95% CI, 0.86-2.09; P = 0.21) and post-hospital mortality rates (24% v 22%; aOR, 1.07; 95% CI, 0.74-1.55; P = 0.72) were also similar for patients in intervention and control hospitals. CONCLUSION: Glucose and HbA1c screening of patients admitted to hospital from EDs does not alone increase detection of previously unidentified diabetes. Adequate resourcing and effective management pathways for patients with newly detected hyperglycaemia and diabetes are needed.

Background and Purpose- We aimed to evaluate the effectiveness of an intervention to improve triage, treatment, and transfer for patients with acute stroke admitted to the emergency department (ED). Methods- A pragmatic, blinded, multicenter, parallel group, cluster randomized controlled trial was conducted between July 2013 and September 2016 in 26 Australian EDs with stroke units and tPA (tissue-type plasminogen activator) protocols. Hospitals, stratified by state and tPA volume, were randomized 1:1 to intervention or usual care by an independent statistician. Eligible ED patients had acute stroke <48 hours from symptom onset and were admitted to the stroke unit via ED. Our nurse-initiated T3 intervention targeted (1) Triage to Australasian Triage Scale category 1 or 2; (2) Treatment: tPA eligibility screening and appropriate administration; clinical protocols for managing fever, hyperglycemia, and swallowing; (3) prompt (<4 hours) stroke unit Transfer. It was implemented using (1) workshops to identify barriers and solutions; (2) face-to-face, online, and written education; (3) national and local clinical opinion leaders; and (4) email, telephone, and site visit follow-up. Outcomes were assessed at the patient level. Primary outcome: 90-day death or dependency (modified Rankin Scale score of ≥2); secondary outcomes: functional dependency (Barthel Index ≥95), health status (Short Form [36] Health Survey), and ED quality of care (Australasian Triage Scale; monitoring and management of tPA, fever, hyperglycemia, swallowing; prompt transfer). Intention-to-treat analysis adjusted for preintervention outcomes and ED clustering. Patients, outcome assessors, and statisticians were masked to group allocation. Results- Twenty-six EDs (13 intervention and 13 control) recruited 2242 patients (645 preintervention and 1597 postintervention). There were no statistically significant differences at follow-up for 90-day modified Rankin Scale (intervention: n=400 [53.5%]; control n=266 [48.7%]; P=0.24) or secondary outcomes. Conclusions- This evidence-based, theory-informed implementation trial, previously effective in stroke units, did not change patient outcomes or clinician behavior in the complex ED environment. Implementation trials are warranted to evaluate alternative approaches for improving ED stroke care. Clinical Trial Registration- URL: http://www.anzctr.org.au.

RESUMEN
STUDY DESIGN: Record linkage study using healthcare utilization and costs data. OBJECTIVE: To identify predictors of higher acute-care treatment costs and length of stay for patients with traumatic spinal cord injury (TSCI). SUMMARY OF BACKGROUND DATA: There are few current or population-based estimates of acute hospitalization costs, length of stay, and other outcomes for people with TSCI, on which to base future planning for specialist SCI health care services. METHODS: Record linkage study using healthcare utilization and costs data; all patients aged more than or equal to 16 years with incident TSCI in the Australian state of New South Wales (June 2013-June 2016). Generalized Linear Model regression to identify predictors of higher acute care treatment costs for patients with TSCI. Scenario analysis quantified the proportionate cost impacts of patient pathway modification. RESULTS: Five hundred thirty-four incident cases of TSCI (74% male). Total cost of all acute index episodes approximately AUD$40.5 (95% confidence interval [CI] ±4.5) million; median cost per patient was AUD$45,473 (Interquartile Range: $15,535-$94,612). Patient pathways varied; acute care was less costly for patients admitted directly to a specialist spinal cord injury unit (SCIU) compared with indirect transfer within 24âhours. Over half (53%) of all patients experienced at least one complication during acute admission; their care was less costly if they had been admitted directly to SCIU. Scenario analysis demonstrated that a reduction of indirect transfers to SCIU by 10% yielded overall cost savings of AUD$3.1 million; an average per patient saving of AUD$5,861. CONCLUSION: Direct transfer to SCIU for patients with acute TSCI resulted in lower treatment costs, shorter length of stay, and less costly complications. Modeling showed that optimizing patient-care pathways can result in significant acute-care cost savings. Reducing potentially preventable complications would further reduce costs and improve longer-term patient outcomes. LEVEL OF EVIDENCE: 3.

BACKGROUND: The Quality in Acute Stroke Care Trial implemented nurse-initiated protocols to manage fever, hyperglycaemia and swallowing (Fever, Sugar, Swallow clinical protocols) achieving a 16% absolute improvement in death and dependency 90-day post-stroke. OBJECTIVE: To examine associations between 90-day death and dependency, and monitoring and treatment processes of in-hospital nursing stroke care targeted in the trial. DESIGN: Secondary data analysis from a single-blind cluster randomised control trial. SETTING: 19 acute stroke units in New South Wales, Australia. PARTICIPANTS: English-speakers ≥18 years with ischaemic stroke or intracerebral haemorrhage arriving at participating stroke units <48 h of stroke onset, excluding those for palliation and without a telephone. METHOD: Data from patients in the 10 intervention hospitals and the nine control hospitals in the QASC trial post-intervention cohort, who had both hospital process of care data and 90-day outcome data were included. Associations between independence at 90-day (modified Rankin Score ≤1) and processes of care for fever, hyperglycaemia, and dysphagia screening were examined using multiple logistic regression adjusting for treatment group, sex, age group, premorbid modified Rankin scale, marital status, education, stroke severity and correlation within hospitals. RESULTS: Of 1126 patients in the post-intervention cohort (intervention or control), 970 had both in-hospital processes of care data and 90-day outcome data. Patients had significantly lower odds of 90-day independence if, within the first 72 h of stroke unit admission, they had one or more: febrile event (≥37.5 °C) (OR 0.47; 95%CI:0.35-0.61; P < 0.0001), higher mean temperature (OR:0.25; 95%CI:0.14-0.45; P < 0.0001), finger-prick blood glucose reading ≥11 mmol/L (OR:0.61; 95%CI:0.47-0.79; P = 0.0002), higher mean blood glucose (OR 0.89; 95%CI:0.84-0.95; P = 0.0006), or failed the swallowing screen (OR 0.35; 95%CI:0.22-0.56; P < 0.0001). Patients had greater odds of independence when: venous blood glucose was taken on admission to hospital or within 2 h of stroke unit admission (OR 1.4; 95%CI:1.01-1.83; P = 0.04); finger-prick blood glucose was measured within 72 h of stroke unit admission (OR 1.3; 95%CI:1.02-1.55; P = 0.03); or when swallowing screening or assessment was performed within 24 h of stroke unit admission (OR 1.8; 95%CI:1.29-2.55; P = 0.0006). CONCLUSION: We have provided robust evidence of the importance of monitoring patients' temperature, blood glucose and swallowing status to improve 90-day stroke outcomes. Routine nursing care can result in significant reduction in death and dependency post-stroke.

INTRODUCTION: Traumatic spinal cord injuries have significant consequences both for the injured individual and the healthcare system, usually resulting in lifelong disability. Evidence has shown that timely medical and surgical interventions can lead to better patient outcomes with implicit cost savings. Potentially preventable secondary complications are therefore indicators of the effectiveness of acute care following traumatic injury. The extent to which policy and clinical variation within the healthcare service impact on outcomes and acute care costs for patients with traumatic spinal cord injury (TSCI) in Australia is not well described. METHODS AND ANALYSIS: A comprehensive data set will be formed using record linkage to combine patient health and administrative records from seven minimum data collections (including costs), with an existing data set of patients with acute TSCI (Access to Care Study), for the time period June 2013 to June 2016. This person-level data set will be analysed to estimate the acute care treatment costs of TSCI in New South Wales, extrapolated nationally. Subgroup analyses will describe the associated costs of secondary complications and regression analysis will identify drivers of higher treatment costs. Mapping patient care and health service pathways of these patients will enable measurement of deviations from best practice care standards and cost-effectiveness analyses of the different pathways. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the New South Wales Population and Health Services Research Ethics Committee. Dissemination strategies include peer-reviewed publications in scientific journals and conference presentations to enable translation of study findings to clinical and policy audiences.

BACKGROUND: Most trials of electronic alcohol screening and brief intervention (e-SBI) have been conducted in young people. The aim of this study was to evaluate the effect of e-SBI in adults with hazardous or harmful drinking. METHODS: This individually randomized, parallel, two-group, double-blind controlled trial was conducted in the outpatient department of a large public hospital in Australia. Consenting adults who scored 5-9 on the AUDIT-C (837/3225; 26%) were randomized in a 1:1 ratio by computer to screening alone (442/837; 53%) or to 10 min of assessment and personalized feedback on their alcohol consumption (comparisons with medical guidelines and age and sex-specific norms), peak blood alcohol concentration, expenditure on alcohol, and risk of alcohol dependence (395/837; 47%). The two primary outcomes, assessed six months after randomization, were the number of standard drinks (10 g ethanol) consumed by participants in the last seven days and their AUDIT score. RESULTS: 693/837 (83%) and 635/837 (76%) participants were followed-up at 6 and 12 months, respectively. There was no statistically significant difference between the groups in the median number of standard drinks consumed in the last seven days (intervention: 12; control: 10.5; rate ratio, 1.12 [95% confidence interval, 0.96-1.31]; P = .17) or in their median AUDIT score (intervention: 7; control: 7; mean difference, 0.28 [-0.42 to 0.98]; P = .44). CONCLUSION: These results do not support the implementation of an e-SBI program comprising personalized feedback and normative feedback for adults with hazardous or harmful drinking in the hospital outpatient setting.

Several animal and human studies have shown that zinc is associated with cellular damage and cardiac dysfunction. This study aims to investigate dietary zinc and the zinc-iron ratio, as predictors of incident cardiovascular disease (CVD) in a large longitudinal study of mid-age Australian women (aged 50-61 years). Data was self-reported and validated food frequency questionnaires were used to assess dietary intake. Energy-adjusted zinc was ranked using quintiles and predictors of incident CVD were examined using stepwise logistic regression. After six years of follow-up, 320 incident CVD cases were established. A positive association between dietary zinc intake, zinc-iron ratio and risk of CVD was observed even after adjusting for potential dietary and non-dietary confounders. Compared to those with the lowest quintile of zinc, those in the highest quintile (Odds Ratio (OR) = 1.67, 95% Confidence Interval (CI) = 1.08-2.62) and zinc-iron ratio (OR = 1.72, 95% CI = 1.05-2.81) had almost twice the odds of developing CVD (p trend = 0.007). This study shows that high dietary zinc intake and zinc-iron ratio is associated with a greater incidence of CVD in women. Further studies are required detailing the source of zinc and iron in diet and their precise roles when compared to other essential nutrients.

Data is scarce on early life exposure to arsenic and its association with malnutrition during infancy. This study followed the nutritional status of a cohort of 120 infants from birth to 9 months of age in an arsenic contaminated area in Bangladesh. Anthropometric data was collected at 3, 6 and 9 months of the infant's age for nutritional assessment whereas arsenic exposure level was assessed via tube well drinking water arsenic concentration at the initiation of the study. Weight and height measurements were converted to Z-scores of weight for age (WAZ-underweight), height for age (HAZ-stunting), weight for height (WHZ-wasting) for children by comparing with WHO growth standard. Arsenic exposure levels were categorized as <50 µg/L and ≥50 µg/L. Stunting rates (<-2 SD) were 10% at 3 months and 44% at both 6 and 9 months. Wasting rates (<-2 SD) were 23.3% at 3 months and underweight rates (<-2 SD) were 25% and 10% at 3 and 6 months of age, respectively. There was a significant association of stunting with household drinking water arsenic exposure ≥50 µg/L at age of 9 months (p = 0.009). Except for stunting at 9 months of age, we did not find any significant changes in other nutritional indices over time or with levels of household arsenic exposure in this study. Our study suggests no association between household arsenic exposure and under-nutrition during infancy; with limiting factors being small sample size and short follow-up. Difference in stunting at 9 months by arsenic exposure at ≥50 µg/L might be a statistical incongruity. Further longitudinal studies are warranted to establish any association.
