An economic evaluation of the Prioritising Responses Of Nurses To deteriorating patient Observations (PRONTO) clinical trial.

BACKGROUND: Early recognition and response to clinical deterioration reduce the frequency of in-hospital cardiac arrests, mortality, and unplanned intensive care unit (ICU) admissions. This study aimed to investigate the impact of the Prioritising Responses Of Nurses To deteriorating patient Observations (PRONTO) intervention on hospital costs and patient length of stay (LOS). METHOD: The PRONTO cluster randomised control trial was conducted to improve nurses' responses to patients with abnormal vital signs. Hospital data were collected pre-intervention (T0) at 6 months (T1) and 12 months (T2) post-intervention. The economic evaluation involved a cost-consequence analysis from the hospital's perspective. Generalised estimating equations were used to estimate the parameters for regression models of the difference in costs and LOS between study groups and time points. RESULTS: Hospital admission data for 6065 patients (intervention group, 3102; control group, 2963) were collected from four hospitals for T0, T1 and T2. The intervention cost was 69.61 A$ per admitted patient, including the additional intervention training for nurses and associated labour costs. The results showed cost savings and a shorter LOS in the intervention group between T0 - T1 and T0 - T2 (cost differences T0 - T1: -364 (95% CI -3,782; 3049) A$ and T0 - T2: -1,710 (95% CI -5,162; 1,742) A$; and LOS differences T0 - T1: -1.10 (95% CI -2.44; 0.24) days and T0 & T2: -2.18 (95% CI -3.53; -0.82) days). CONCLUSION: The results of the economic analysis demonstrated that the PRONTO intervention improved nurses' responses to patients with abnormal vital signs and significantly reduced hospital LOS by two days at 12 months in the intervention group compared to baseline. From the hospital's perspective, savings from reduced hospitalisations offset the costs of implementing PRONTO.

The association between loneliness with health service use and quality of life among informal carers in Australia.

OBJECTIVE: The demanding nature of caregiving and limited social support can lead to informal carers experiencing loneliness, which can impact their well-being and overall health service use (HSU). The study aims to examine the association between loneliness with HSU and Health state utility values among informal carers in Australia. METHODS: Data were derived from three waves (2009, 2013, and 2017) of the nationally representative longitudinal Household Income and Labour Dynamics of Australia (HILDA) survey, focusing on adult informal carers. Outcome measures included visits to the General Practitioner, the number of hospital admissions, and the SF-6D score. Generalized Estimating Equations (GEE) analysis was conducted to explore the associations between loneliness and HSU, as well as loneliness and utility values (based on SF-6D) while adjusting for age, sex, education, marital status, income, and physical/mental health conditions. RESULTS: After controlling for covariates, lonely carers reported lower utility values (IRR = 0.91, 95%CI [0.89, 0.93], p < 0.001) compared to non-lonely carers. Lonely carers reported a higher number of GP visits (IRR = 1.18, 95% CI [1.04, 1.36], p < 0.05) as well as a higher likelihood of visiting specialists (AOR = 1.31, p = 0.046) and hospital doctors (AOR = 1.42, p = 0.013) compared to the non-lonely carers. CONCLUSIONS: The findings of this study highlight the relationship between loneliness on both healthcare utilization and carers' overall well-being. Addressing loneliness through targeted interventions and social support systems can help improve health outcomes and potentially reduce the overall healthcare costs among informal carers in Australia.

Vital sign assessment and nursing interventions in medical and surgical patients with rapid response system triggers.

AIM(S): To explore vital sign assessment (both complete and incomplete sets of vital signs), and escalation of care per policy and nursing interventions in response to clinical deterioration. DESIGN: This cohort study is a secondary analysis of data from the Prioritising Responses of Nurses To deteriorating patient Observations cluster randomised controlled trial of a facilitation intervention on nurses' vital sign measurement and escalation of care for deteriorating patients. METHODS: The study was conducted in 36 wards at four metropolitan hospitals in Victoria, Australia. Medical records of all included patients from the study wards during three randomly selected 24-h periods within the same week were audited at three time points: pre-intervention (June 2016), and at 6 (December 2016) and 12 months (June 1017) post-intervention. Descriptive statistics were used to summarise the study data, and relationships between variables were examined using chi-square test. RESULTS: A total of 10,383 audits were conducted. At least one vital sign measurement was documented every 8 h in 91.6% of audits, and a complete set of vital signs was documented every 8 h in 83.1% of audits. There were pre-Medical Emergency Team, Medical Emergency Team or Cardiac Arrest Team triggers in 25.8% of audits. When triggers were present, a rapid response system call occurred in 26.8% of audits. There were 1350 documented nursing interventions in audits with pre-Medical Emergency Team (n = 2403) or Medical Emergency Team triggers (n = 273). One or more nursing interventions were documented in 29.5% of audits with pre-Medical Emergency Team triggers and 63.7% of audits with Medical Emergency Team triggers. CONCLUSION: When rapid response system triggers were documented, there were gaps in escalation of care per policy; however, nurses undertook a range of interventions within their scope of practice in response to clinical deterioration. RELEVANCE TO CLINICAL PRACTICE: Medical and surgical ward nurses in acute care wards frequently engage in vital sign assessment. Interventions by medical and nurgical nurses may occur prior to, or in parallel with calling the rapid response system. Nursing interventions are a key but under-recognised element of the organisational response to deteriorating patients. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Nurses engage in a range of nursing interventions to manage deteriorating patients, (aside from rapid response system activation) that are not well understood, nor well described in the literature to date. IMPACT: This study addresses the gap in the literature regarding nurses' management of deteriorating patients within their scope of practice (aside from RRS activation) in real world settings. When rapid response system triggers were documented, there were gaps in escalation of care per policy; however, nurses undertook a range of interventions within their scope of practice in response to clinical deterioration. The results of this research are relevant to nurses working on medical and surgical wards. REPORTING METHOD: The trial was reported according to the Consolidated Standards of Reporting Trials extension for Cluster Trials recommendations, and this paper is reported according to the Strengthening the Reporting of Observational Studies in Epidemiology Statement.

Cost-Utility and Cost-effectiveness of MoodSwings 2.0, an Internet-Based Self-management Program for Bipolar Disorder: Economic Evaluation Alongside a Randomized Controlled Trial.

BACKGROUND: Internet-delivered psychosocial interventions can overcome barriers to face-to-face psychosocial care, but limited evidence supports their cost-effectiveness for people with bipolar disorders (BDs). OBJECTIVE: This study aimed to conduct within-trial cost-effectiveness and cost-utility analyses of an internet-based intervention for people with BD, MoodSwings 2.0, from an Australian health sector perspective. METHODS: MoodSwings 2.0 included an economic evaluation alongside an international, parallel, and individually stratified randomized controlled trial comparing an internet-based discussion forum (control; group 1), a discussion forum plus internet-based psychoeducation (group 2), and a discussion forum plus psychoeducation and cognitive behavioral tools (group 3). The trial enrolled adults (aged 21 to 65 years) with a diagnosis of BD assessed by telephone using a structured clinical interview. Health sector costs included intervention delivery and additional health care resources used by participants over the 12-month trial follow-up. Outcomes included depression symptoms measured by the Montgomery-Åsberg Depression Rating Scale (MADRS; the trial primary outcome) and quality-adjusted life years (QALYs) calculated using the short-form 6-dimension instrument derived from the 12-item version of the short-form health survey. Average incremental cost-effectiveness (cost per MADRS score) and cost-utility (cost per QALY) ratios were calculated using estimated mean differences between intervention and control groups from linear mixed effects models in the base case. RESULTS: In total, 304 participants were randomized. Average health sector cost was lowest for group 2 (Aus $9431, SD Aus $8540; Aus $1=US $0.7058) compared with the control group (Aus $15,175, SD Aus $17,206) and group 3 (Aus $15,518, SD Aus $30,523), but none was statistically significantly different. The average QALYs were not significantly different among the groups (group 1: 0.627, SD 0.062; group 2: 0.618, SD 0.094; and group 3: 0.622, SD 0.087). The MADRS scores were previously shown to differ significantly between group 2 and the control group at all follow-up time points (P<.05). Group 2 was dominant (lower costs and greater effects) compared with the control group for average incremental cost per point decrease in MADRS score over 12 months (95% CI dominated to Aus $331). Average cost per point change in MADRS score for group 3 versus the control group was dominant (95% CI dominant to Aus $22,585). Group 2 was dominant (95% CI Aus $43,000 to dominant) over the control group based on lower average health sector cost and average QALY benefit of 0.012 (95% CI -0.009 to 0.033). Group 3, compared with the control group, had an average incremental cost-effectiveness ratio of dominant (95% CI dominated to Aus $19,978). CONCLUSIONS: Web-based psychoeducation through MoodSwings 2.0 has the potential to be a cost-effective intervention for people with BD. Additional research is needed to understand the lack of effectiveness for the addition of cognitive behavioral tools with the group 3 intervention.

Use of an audit with feedback implementation strategy to promote medication error reporting by nurses.

AIMS AND OBJECTIVES: To outline the development and effect of an audit with feedback implementation strategy that intended to increase the rate of voluntary medication error reporting by nurses. BACKGROUND: Medication errors are a serious global health issue. Audit with feedback is a widely used implementation strategy that has potential to modify nurses' reporting behaviour and improve medication error reporting rates. DESIGN: Quasi-experimental implementation study (fulfilling the TIDieR checklist) with two pairs of matched wards at a private hospital in Australia was conducted from March 2015-September 2016. One ward from each pair was randomised to either the intervention or control group. METHOD: Nurses within intervention wards received audit with feedback on a quarterly basis over a 12-month implementation period. Control wards underwent quarterly audits only (without feedback). Feedback consisted of a one-page infographic poster, with content based on medication error data obtained from audits and the hospitals' risk management system (RiskMan). The primary outcome-rate of medication errors reported per month-was determined in both groups at pre-implementation, implementation and postimplementation phases. Differences between groups were compared using generalised linear mixed models with Poisson distribution and log link. RESULTS: A nonsignificant intervention effect was found for rate of medication errors reported per month. Interestingly, when combining data from both groups, a significant increasing time trend was observed for medication errors reported per month across pre-implementation and implementation phases (80% increase). CONCLUSIONS: The audit with feedback strategy developed in the present study did not effectively influence the voluntary reporting of medication errors by nurses. RELEVANCE TO CLINICAL PRACTICE: Despite the lack of intervention effects, the use of a published checklist to optimise the reporting quality of this study will contribute to the field by furthering the understanding of how to enhance audit with feedback implementation strategies for nurses.

The impact of translated reminder letters and phone calls on mammography screening booking rates: Two randomised controlled trials.

INTRODUCTION: Participation in mammographic screening for breast cancer in Australia is approximately 54% among the general population, but screening among women from some culturally and linguistically diverse (CALD) backgrounds is lower. BreastScreen Victoria apply strategies to increase screening including reminder letters and phone calls; however, these are usually provided in English. Using intervention strategies generated from the Ophelia (OPtimise HEalth LIteracy and Access) community co-design process, translated mammography reminder letters and in-language phone calls were tested within two randomised control trials (RCTs). METHODS AND ANALYSIS: Women aged 50-75 years who were due for their 2-yearly screening mammography (for RCT#1) or were under-screened, i.e. ≥27 months since last screen (for RCT#2) were randomised into intervention or control groups. RCT#1 compared sending women routine reminder letters (English only) with translated (Arabic or Italian) letters. RCT#2 compared reminder telephone calls to women in their preferred language (Arabic or Italian) to no telephone call. The primary outcome for each trial was screening booking rates within 14-days. Primary outcomes were tested using Pearson's chi-square test. Rates within language group (incidence ratio: IR) were compared using the Cochran-Mantel-Haenszel test. RESULTS: For RCT#1 (letters) 1,032 women were randomised into the intervention arm or to usual care. Uptake of screening bookings was similar between both groups, with no differences observed by language group. For RCT#2 (phone calls), 195 women were randomised to the intervention group or to usual care. Overall, 64.2% of women in the intervention arm and 6% in the control arm booked a screening appointment within 14 days (p<0.0001). The IR (95%CI) of booking was 10.1 (3.9, 26.3) times higher among Italian women, and 11.6 (2.9, 46.5) times higher among Arabic women in the intervention compared to usual care groups. DISCUSSION AND CONCLUSION: A service improvement initiative derived from community members and breast screen providers was found to be highly effective. This evidence informed the service provider, BreastScreen Victoria, who have implemented these improvements into routine practice to improve screening among CALD groups and reduce health inequalities.

Economic evaluation of a phase III international randomised controlled trial of very early mobilisation after stroke (AVERT).

OBJECTIVES: While very early mobilisation (VEM) intervention for stroke patients was shown not to be effective at 3 months, 12 month clinical and economical outcomes remain unknown. The aim was to assess cost-effectiveness of a VEM intervention within a phase III randomised controlled trial (RCT). DESIGN: An economic evaluation alongside a RCT, and detailed resource use and cost analysis over 12 months post-acute stroke. SETTING: Multi-country RCT involved 58 stroke centres. PARTICIPANTS: 2104 patients with acute stroke who were admitted to a stroke unit. INTERVENTION: A very early rehabilitation intervention within 24 hours of stroke onset METHODS: Cost-utility analyses were undertaken according to pre-specified protocol measuring VEM against usual care (UC) based on 12 month outcomes. The analysis was conducted using both health sector and societal perspectives. Unit costs were sourced from participating countries. Details on resource use (both health and non-health) were sourced from cost case report form. Dichotomised modified Rankin Scale (mRS) scores (0 to 2 vs 3 to 6) and quality adjusted-life years (QALYs) were used to compare the treatment effect of VEM and UC. The base case analysis was performed on an intention-to-treat basis and 95% CI for cost and QALYs were estimated by bootstrapping. Sensitivity analysis were conducted to examine the robustness of base case results. RESULTS: VEM and UC groups were comparable in the quantity of resource use and cost of each component. There were no differences in the probability of achieving a favourable mRS outcome (0.030, 95% CI -0.022 to 0.082), QALYs (0.013, 95% CI -0.041 to 0.016) and cost (AUD1082, 95% CI -$2520 to $4685 from a health sector perspective or AUD102, 95% CI -$6907 to $7111, from a societal perspective including productivity cost). Sensitivity analysis achieved results with mostly overlapped CIs. CONCLUSIONS: VEM and UC were associated with comparable costs, mRS outcome and QALY gains at 12 months. Compared with to UC, VEM is unlikely to be cost-effective. The long-term data collection during the trial also informed resource use and cost of care post-acute stroke across five participating countries.

Association between area-level socioeconomic status, accessibility and diabetes-related hospitalisations: a cross-sectional analysis of data from Western Victoria, Australia.

OBJECTIVE: Hospitalisation rates for many chronic conditions are higher in socioeconomically disadvantaged and less accessible areas. We aimed to map diabetes hospitalisation rates by local government area (LGA) across Western Victoria, Australia, and investigate their association with socioeconomic status (SES) and accessibility/remoteness. DESIGN: Cross-sectional study METHODS: Data were acquired from the Victorian Admitted Episodes Dataset for all hospitalisations (public and private) with a diagnosis of type 1 or type 2 diabetes mellitus during 2011-2014. Crude and age-standardised hospitalisation rates (per 1000 population per year) were calculated by LGA for men, women and combined data. Associations between accessibility (Accessibility/Remoteness Index of Australia, ARIA), SES (Index of Relative Socioeconomic Advantage and Disadvantage, IRSAD) and diabetes hospitalisation were investigated using Poisson regression analyses. RESULTS: Higher LGA-level accessibility and SES were associated with higher rates of type 1 and type 2 diabetes hospitalisation, overall and for each sex. For type 1 diabetes, higher accessibility (ARIA category) was associated with higher hospitalisation rates (men incidence rate ratio [IRR]=2.14, 95% CI 1.64 to 2.80; women IRR=2.45, 95% CI 1.87 to 3.19; combined IRR=2.30, 95% CI 1.69 to 3.13; all p<0.05). Higher socioeconomic advantage (IRSAD decile) was also associated with higher hospitalisation rates (men IRR=1.25, 95% CI 1.09 to 1.43; women IRR=1.32, 95% CI 1.16 to 1.51; combined IRR=1.23, 95% CI 1.07 to 1.42; all p<0.05). Similarly, for type 2 diabetes, higher accessibility (ARIA category) was associated with higher hospitalisation rates (men IRR=2.49, 95% CI 1.81 to 3.43; women IRR=2.34, 95% CI 1.69 to 3.25; combined IRR=2.32, 95% CI 1.66 to 3.25; all p<0.05) and higher socioeconomic advantage (IRSAD decile) was also associated with higher hospitalisation rates (men IRR=1.15, 95% CI 1.02 to 1.30; women IRR=1.14, 95% CI 1.01 to 1.28; combined IRR=1.13, 95% CI 1.00 to 1.27; all p<0.05). CONCLUSION: Our observations could indicate self-motivated treatment seeking, and better specialist and hospital services availability in the advantaged and accessible areas in the study region. The determinants for such variations in hospitalisation rates, however, are multifaceted and warrant further research.

Association Between Statin Use and Depressive Symptoms in a Large Community-Dwelling Older Population Living in Australia and the USA: A Cross-Sectional Study.

BACKGROUND: Statin use has been frequently associated with depressive symptoms in an older population. However, the nature of this association is uncertain in the literature. In this study, we aimed to investigate the association of statin intake and the prevalence of depressive symptoms in healthy community-dwelling older adults living in Australia and the USA. METHODS: We analysed baseline data from 19,114 participants, over 70 years of age (over 65 years of age, if from an ethnic minority). The association of self-reported statin use and prevalence of depressive symptoms, as measured by a validated depression scale [Center for Epidemiological Studies Depression Scale (CES-D 10)], was determined using logistic regression models. Multivariable logistic models were implemented to account for important demographics and other lifestyle and socioeconomic factors, such as sex, age, living status, education and smoking history. RESULTS: A total of 5987 individuals were statin users. Of those, 633 (10.6%) had depressive symptoms (CES-D 10 cut-off ≥ 8), compared with 1246 (9.5%) of the non-statin users. In the unadjusted model, statin use was associated with an increase in prevalence of depressive symptoms (odds ratio 1.13, confidence interval 1.02-1.25, p = 0.02). However, after adjusting for important demographic and socioeconomic factors, the use of statins was not significantly associated with depressive symptoms (odds ratio 1.09, confidence interval 0.98-1.20, p = 0.11). In secondary analyses, only simvastatin was marginally associated with an increased prevalence of depressive symptoms. Statins were associated with a decreased prevalence of depressive symptoms in individuals with severe obesity (body mass index > 35 kg/m2) and an increased prevalence in participants between 75 and 84 years of age. CONCLUSION: This study in a large community-dwelling older population did not show any association of statins with late-life depressive symptoms, after accounting for important socioeconomic and demographic factors. Confounding by indication is an important issue to be addressed in future pharmacoepidemiologic studies of statins.

Variation in the prevalence of depression and patterns of association, sociodemographic and lifestyle factors in community-dwelling older adults in six low- and middle-income countries.

BACKGROUND: Data from the World Health Organization Study on global AGEing and adult health (SAGE) were used to estimate the prevalence of depression in older adults in six low- and middle-income countries (LMICs), namely China, Ghana, India, Mexico, the Russian Federation, and South Africa, and to examine the relationship between demographic and lifestyle characteristics and depression. METHOD: A total of 33,421 participants aged ≥ 50 years were included. A set of diagnostic questions from the World Mental Health Survey was used within SAGE to define depression. RESULTS: The crude population prevalence of depression was 7.4% [95%CI: 6.5%-8.3%] ranging from 1.5% in China to 15.2% in India. It was higher in females 8.6% [7.6%-9.6%] compared to males 6.1% [5.0%-7.2%]. The age-standardized prevalence of depression was 7.8% [6.3%-9.6%] in pooled data, 8.9% [6.9%-11.1%] in females and 6.6% [4.6%-9.0%] in males. Greater fruit (0.89[0.84-0.93]) and vegetable intake (0.94 [0.89-1.00]) was associated with a lower prevalence of depression. Furthermore, those who were older, female, underweight, and with lower education and lower wealth, had higher prevalence of depression. LIMITATIONS: The cross-sectional design of this study precluded conclusions on causality. CONCLUSION: In nationally-representative samples of older adults in six LMICs, an average of one in every 13 participants suffered from depression. The prevalence of depression varied considerably between countries, sexes, and with wealth and educational disadvantage. Increased fruit and vegetable intake appeared to co-occur with significantly lower rates of depression, suggesting diet as a modifiable factor for addressing depression burden.

The SMILES trial: an important first step.

The SMILES trial was the first intervention study to test dietary improvement as a treatment strategy for depression. Molendijk et al. propose that expectation bias and difficulties with blinding might account for the large effect size. While we acknowledge the issue of expectation bias in lifestyle intervention trials and indeed discuss this as a key limitation in our paper, we observed a strong correlation between dietary change and change in depression scores, which we argue is consistent with a causal effect and we believe unlikely to be an artefact of inadequate blinding. Since its publication, our results have been largely replicated and our recent economic evaluation of SMILES suggests that the benefits of our approach extend beyond depression. We argue that the SMILES trial should be considered an important, albeit preliminary, first step in the field of nutritional psychiatry research.

Social marketing and community mobilisation to reduce underage alcohol consumption in Australia: A cluster randomised community trial.

BACKGROUND AND AIMS: In many countries adolescent alcohol use is a major health problem. To supplement national policies, it is important to trial community interventions as a potential strategy to prevent adolescent alcohol use. METHODS: This study evaluated a multicomponent community intervention that included community mobilisation, social marketing, and the monitoring of alcohol sales to minors. Evaluation was a clustered randomised trial design with 14 intervention and 14 control communities. Prior to randomisation, communities were matched on socioeconomic status and location. Intervention communities were not blinded. PARTICIPANTS: 3545 Year 8 students (M = 12 years) were surveyed at baseline from 75 schools; 3377 students were surveyed post intervention in 2013 from 54 schools. OUTCOMES: It was hypothesised that the primary outcome, individual alcohol consumption in last 30 days, after the intervention would be 15% lower in intervention communities. Secondary outcomes were consumption in the past year and intention not to drink before age 18. RESULTS: The intervention communities showed larger relative reductions compared to the controls in last 30-day consumption and past year (10%), but not significantly different. A significantly lower proportion of participants in the intervention community (63%), compared to the controls (71%), reported intending to drink before 18 years old. Subgroup analysis identified regional and state differences for some secondary measures. CONCLUSIONS: Intervention assignment was associated with lower adolescent intention to drink before the age of 18. However, more intensive and longer-term intervention may be required to measure significant differences in behaviour change. TRIAL REGISTRATION: ACTRN12612000384853.

Evaluating the Impact of the Dementia Care in Hospitals Program (DCHP) on Hospital-Acquired Complications: Study Protocol.

Despite the increasing number of older people, many with cognitive impairment (CI), in hospitals, there is yet to be an evaluation of hospital-wide interventions improving the management of those with CI. In hospitalized patients with CI, there are likely to be associations between increased complications that impact on outcomes, length of stay, and costs. This prospective study will evaluate the effectiveness of an established hospital CI support program on patient outcomes, patient quality of life, staff awareness of CI, and carer satisfaction. Using a stepped-wedge, continuous-recruitment method, the pre-intervention patient data will provide the control data for usual hospital care. The intervention, the Dementia Care in Hospitals Program, provides hospital-wide CI awareness and support education, and screening for all patients aged 65+, along with a bedside alert, the Cognitive Impairment Identifier. The primary outcome is a reduction in hospital-acquired complications: urinary tract infections, pressure injuries, pneumonia and delirium. Secondary outcome measures include cost effectiveness, patient quality of life, carer satisfaction, staff awareness of CI, and staff perceived impact of care. This large-sample study across four sites offers an opportunity for research evaluation of health service functioning at a whole-of-hospital level, which is important for sustainable change in hospital practice.

The epidemiology of hip fractures across western Victoria, Australia.

BACKGROUND: Hip fractures are associated with considerable morbidity and mortality. Hip fracture incidence varies across different levels of accessibility/remoteness and socioeconomic status (SES). As part of the Ageing, Chronic Disease and Injury Study, we aimed to map the pattern of hip fractures across the western region of the Australian state of Victoria, which contains a range of remoteness levels and SES. METHODS: Data on hip fractures resulting in hospital admission were extracted from the Victorian Admitted Episodes Dataset (VAED) for men and women aged 40+years during 2010-2013 inclusive. An age-adjusted incidence rate (per 10,000population/year) was calculated for the entire region. Crude incidence rates and length of acute care hospital stay (excluding rehabilitation) were calculated for each Local Government Area (LGA). The impact of aggregated age, accessibility/remoteness index of Australia (ARIA) and SES on hip fracture rates aggregated across LGAs was determined using Poisson regression. RESULTS: For men, the age-standardised rate of hospitalisations for hip fracture across the whole region was 19.2 per 10,000population/year (95%CI 18.0-20.4) and for women, 40.0 (95%CI 38.3-41.7). The highest incidence rates for both sexes occurred in the less accessible LGAs of Yarriambiack and Hindmarsh, as well as the LGA with the lowest SES, Central Goldfields. In both sexes, approximately two thirds of individuals were discharged from acute hospital care within 14days. Increasing age, higher remoteness and lower SES were all associated with higher hip fracture rates. CONCLUSION: Crude incidence rates varied by location. Given that a high proportion of patients had acute hospital care of ≤14days, and accessibility and SES were associated with hip fracture rates, these results can inform policy and provide a model for other groups to conduct similar research in their local environment.

Pharmacy Diabetes Screening Trial: protocol for a pragmatic cluster-randomised controlled trial to compare three screening methods for undiagnosed type 2 diabetes in Australian community pharmacy.

INTRODUCTION: With the rising prevalence of type 2 diabetes in Australia, screening and earlier diagnosis is needed to provide opportunities to intervene with evidence-based lifestyle and treatment options to reduce the individual, social and economic impact of the disease. The objectives of the Pharmacy Diabetes Screening Trial are to compare the clinical effectiveness and cost-effectiveness of three screening models for type 2 diabetes in a previously undiagnosed population. METHODS AND ANALYSIS: The Pharmacy Diabetes Screening Trial is a pragmatic cluster randomised controlled trial to be conducted in 363 community pharmacies across metropolitan, regional and remote areas of Australia, randomly allocated by geographical clusters to one of three groups, each with 121 pharmacies and 10 304 screening participants. The three groups are: group A: risk assessment using a validated tool (AUSDRISK); group B: AUSDRISK assessment followed by point-of-care glycated haemoglobin testing; and group C: AUSDRISK assessment followed by point-of-care blood glucose testing. The primary clinical outcome measure is the proportion of newly diagnosed cases of type 2 diabetes. Primary outcome comparisons will be conducted using the Cochran-Mantel-Haenszel test to account for clustering. The secondary clinical outcomes measures are the proportion of those who (1) are referred to the general practitioner (GP), (2) take up referral to the GP, (3) are diagnosed with pre-diabetes, that is, impaired glucose tolerance or impaired fasting glucose and (4) are newly diagnosed with either diabetes or pre-diabetes. The economic outcome measure is the average cost (direct and indirect) per confirmed new case of diagnosed type 2 diabetes based on the incremental net trial-based costs of service delivery and the associated incremental longer term health benefits from a health funder perspective. ETHICS AND DISSEMINATION: The protocol has been approved by the Human Research Ethics Committees at University of Sydney and Deakin University. Results will be available on the Sixth Community Pharmacy Agreement website and will be published in peer reviewed journals. TRIAL REGISTRATION NUMBER: ACTRN12616001240437; Pre-results.

Prioritising Responses Of Nurses To deteriorating patient Observations (PRONTO) protocol: testing the effectiveness of a facilitation intervention in a pragmatic, cluster-randomised trial with an embedded process evaluation and cost analysis.

BACKGROUND: Vital signs are the primary indicator of physiological status and for determining the need for urgent clinical treatment. Yet, if physiological signs of deterioration are missed, misinterpreted or mismanaged, then critical illness, unplanned intensive care admissions, cardiac arrest and death may ensue. Although evidence demonstrates the benefit of early recognition and management of deteriorating patients, failure to escalate care and manage deteriorating patients remains a relatively frequent occurrence in hospitals. METHODS/DESIGN: A pragmatic cluster-randomised controlled trial design will be used to measure clinical effectiveness and cost of a facilitation intervention to improve nurses' vital sign measurement, interpretation, treatment and escalation of care for patients with abnormal vital signs. A cost consequence analysis will evaluate the intervention cost and effectiveness, and a process evaluation will determine how the implementation of the intervention contributes to outcomes. We will compare clinical outcomes and costs from standard implementation of clinical practice guidelines (CPGs) to facilitated implementation of CPGs. The primary outcome will be adherence to the CPGs by nurses, as measured by escalation of care as per organisational policy. The study will be conducted in four Australian major metropolitan teaching hospitals. In each hospital, eight to ten wards will be randomly allocated to intervention and control groups. Control wards will receive standard implementation of CPGs, while intervention wards will receive standard CPG implementation plus facilitation, using facilitation methods and processes tailored to the ward context. The intervention will be administered to all nursing staff at the ward level for 6 months. At each hospital, two types of facilitators will be provided: a hospital-level facilitator as the lead; and two ward-level facilitators for each ward. DISCUSSION: This study uses an innovative, networked approach to facilitation to enable uptake of CPGs. Findings will inform the intervention utility and knowledge translation measurement approaches. If successful, the study methodology and intervention has potential for translation to other health care standards.

Cost of high prevalence mental disorders: Findings from the 2007 Australian National Survey of Mental Health and Wellbeing.

OBJECTIVE: The aim of this project was to detail the costs associated with the high prevalence mental disorders (depression, anxiety-related and substance use) in Australia, using community-based, nationally representative survey data. METHODS: Respondents diagnosed, within the preceding 12 months, with high prevalence mental disorders using the Confidentialised Unit Record Files of the 2007 National Survey of Mental Health and Wellbeing were analysed. The use of healthcare resources (hospitalisations, consultations and medications), productivity loss, income tax loss and welfare benefits were estimated. Unit costs of healthcare services were obtained from the Independent Hospital Pricing Authority, Medicare and Pharmaceutical Benefits Scheme. Labour participation rates and unemployment rates were determined from the National Survey of Mental Health and Wellbeing. Daily wage rates adjusted by age and sex were obtained from Australian Bureau of Statistics and used to estimate productivity losses. Income tax loss was estimated based on the Australian Taxation Office rates. The average cost of commonly received Government welfare benefits adjusted by age was used to estimate welfare payments. All estimates were expressed in 2013-2014 AUD and presented from multiple perspectives including public sector, individuals, private insurers, health sector and societal. RESULTS: The average annual treatment cost for people seeking treatment was AUD660 (public), AUD195 (individual), AUD1058 (private) and AUD845 from the health sector's perspective. The total annual healthcare cost was estimated at AUD974m, consisting of AUD700m to the public sector, AUD168m to individuals, and AUD107m to the private sector. The total annual productivity loss attributed to the population with high prevalence mental disorders was estimated at AUD11.8b, coupled with the yearly income tax loss at AUD1.23b and welfare payments at AUD12.9b. CONCLUSION: The population with high prevalence mental disorders not only incurs substantial cost to the Australian healthcare system but also large economic losses to society.

Minimising post-operative risk using a Post-Anaesthetic Care Tool (PACT): protocol for a prospective observational study and cost-effectiveness analysis.

INTRODUCTION: While the risk of adverse events following surgery has been identified, the impact of nursing care on early detection of these events is not well established. A systematic review of the evidence and an expert consensus study in post-anaesthetic care identified essential criteria for nursing assessment of patient readiness for discharge from the post-anaesthetic care unit (PACU). These criteria were included in a new nursing assessment tool, the Post-Anaesthetic Care Tool (PACT), and incorporated into the post-anaesthetic documentation at a large health service. The aim of this study is to test the clinical reliability of the PACT and evaluate whether the use of PACT will (1) enhance the recognition and response to patients at risk of deterioration in PACU; (2) improve documentation for handover from PACU nurse to ward nurse; (3) result in improved patient outcomes and (4) reduce healthcare costs. METHODS AND ANALYSIS: A prospective, non-randomised, pre-implementation and post-implementation design comparing: (1) patients (n=750) who have surgery prior to the implementation of the PACT and (2) patients (n=750) who have surgery after PACT. The study will examine the use of the tool through the observation of patient care and nursing handover. Patient outcomes and cost-effectiveness will be determined from health service data and medical record audit. Descriptive statistics will be used to describe the sample and compare the two patient groups (pre-intervention and post-intervention). Differences in patient outcomes between the two groups will be compared using the Cochran-Mantel-Haenszel test and regression analyses and reported as ORs with the corresponding 95% CIs. CONCLUSIONS: This study will test the clinical reliability and cost-effectiveness of the PACT. It is hypothesised that the PACT will enable nurses to recognise and respond to patients at risk of deterioration, improve handover to ward nurses, improve patient outcomes, and reduce healthcare costs.

The spatial distribution of esophageal and gastric cancer in Caspian region of Iran: an ecological analysis of diet and socio-economic influences.

Recent studies have suggested a systematic geographic pattern of esophageal cancer (EC) and gastric cancer (GC) incidence in the Caspian region of Iran. The aims of this study were to investigate the association between these cancers and the region's dietary and socioeconomic risk factors and to map EC and GC after adjustment for the risk factors and the removal of random and geographic variations from area specific age standardised incidence ratios (SIRs). We obtained cancer data from the Babol cancer registry from 2001 to 2005, socioeconomic indices from the Statistical Centre of Iran, and dietary patterns from the control group in a case control study conducted in the study region. Regression models were fitted to identify significant covariates, and clusters of elevated rates were identified. We found evidence of systematic clustering for EC and GC in men and women and both sexes combined. EC and GC SIRs were lower in urban areas, and were also lower in areas of high income. EC SIRs were lower in areas with higher proportions of people having unrestricted food choice and higher in areas with higher proportions of people with restricted food choice. EC and GC were associated with aggregated risk factors, including income, urbanisation, and dietary patterns. These variables represent the influence of improved lifestyle which has coincided with a decrease in upper gastrointestinal cancer frequency over recent decades but which has not necessarily been uniform throughout the region.
