Abstract Background Prostate cancer is the most common internal malignancy in Australian men, and although most patients have good survival outcomes, treatment toxicities can impair function, leading to diminished quality of life for prostate cancer survivors. Socioeconomic disadvantage and geographical remoteness have been shown to be related to worse oncologic outcomes, and it is expected that they would similarly influence functional outcomes in prostate cancer. Methods Using data from the Victorian Prostate Cancer Outcomes Registry (n = 10,924), we investigated functional outcomes as measured by the Expanded Prostate Cancer Index Composite-26 (EPIC-26) following prostate cancer treatment, focusing on associations with socioeconomic status and geographical remoteness and controlling for clinicopathologic characteristics. A single composite score was developed from the five separate EPIC-26 domains for use in geo-mapping. Results A total of 7690 patients had complete EPIC-26 data, allowing mapping hotspots of poor function using our composite score. These hotspots were observed to relate to areas of socioeconomic disadvantage. Significant heterogeneity in outcomes was seen in urban areas, with hotspots of good and poor function. Both socioeconomic disadvantage and geographical remoteness were found to predict for worse functional outcomes, although only the former is significant on multivariate analysis. Conclusions Geo-mapping of functional outcomes in prostate cancer has the potential to guide health care service provision and planning. A nuanced policy approach is required so as not to miss disadvantaged patients who live in urban areas. We have demonstrated the pot

BACKGROUND: Robot-assisted radical prostatectomy (RARP) rates have been increasing worldwide despite a lack of evidence of superior patient-reported outcomes (PROs) compared to open radical prostatectomy (ORP). METHODS: This retrospective study included men who contributed data to the Prostate Cancer Outcomes Registry-Victoria (PCOR-Vic), underwent ORP or RARP between January 2014 and May 2018, and completed the EPIC-26 questionnaire 12 months post-surgery. Urinary and sexual bother items, the urinary incontinence domain score, the urinary irritative/obstructive domain score, the sexual domain score and the pad usage item from the EPIC-26 questionnaire were compared between the two cohorts. Unmatched and propensity score matched cohorts were used to determine if there were differences in urinary and sexual PROs between ORP and RARP after accounting for the patient case-mix and surgeon characteristics. RESULTS: Of 3826 patients undergoing radical prostatectomy (RP), 1047 received ORP and 2779 received RARP. Propensity score matching reduced the magnitude of the observed differences in four out of six outcomes (urinary bother, urinary incontinence domain, pad usage and sexual domain). Using a propensity score matched cohort, there were no statistically significant differences for RARP patients, compared to ORP patients, in terms of urinary bother (Rd = 0.47%, P = 0.707), urinary incontinence domain scores (Coeff = - 0.84, P = 0.506), urinary irritative/obstructive domain scores (Coeff = 1.03, P = 0.105), pad usage (Rd = - 0.75%, P = 0.771) and sexual bother (Rd = - 0.89%, P = 0.731). RARP patients had slightly higher sexual domain scores (Coeff = 3.65, P = 0.005). CONCLUSION: There were no differences in urinary PROs between ORP and RARP when assessed 12 months post-surgery. The sexual domain slightly favoured RARP, however this was not deemed clinically significant.

OBJECTIVE: Feeling depressed and lethargic are common side effects of prostate cancer (PCa) and its treatments. We examined the incidence and severity of feeling depressed and lack of energy in patients in a population based PCa registry. METHODS: We included men diagnosed with PCa between 2015 and 2019 in Victoria, Australia, and enrolled in the Prostate Cancer Outcomes Registry. The primary outcome measures were responses to two questions on the Expanded Prostate Cancer Index Composite (EPIC-26) patient reported instrument: problems with feeling depressed and problems with lack of energy 12 months following treatment. We evaluated associations between these and age, cancer risk category, treatment type, and urinary, bowel, and sexual function. RESULTS: Both outcome questions were answered by 9712 out of 12,628 (77%) men. 981 patients (10%) reported at least moderate problems with feeling depressed; 1563 (16%) had at least moderate problems with lack of energy and 586 (6.0%) with both. Younger men reported feeling depressed more frequently than older men. Lack of energy was more common for treatments that included androgen deprivation therapy than not (moderate/big problems: 31% vs. 13%), irrespective of disease risk category. Both outcomes were associated with poorer urinary, bowel, and sexual functional domain scores. CONCLUSIONS: Self-reported depressive feelings and lack of energy were frequent in this population-based registry. Problems with feeling depressed were more common in younger men and lack of energy more common in men having hormonal treatment. Clinicians should be aware of the incidence of these symptoms in these at-risk groups and be able to screen for them.

BACKGROUND: National cardiac registries are increasingly used for informing health policy, improving the quality and cost-effectiveness of patient care, clinical research, and monitoring the safety of novel treatments. However, the quality of registries is variable. We aimed to assess the characteristics and quality of national cardiac registries across all subspecialties of cardiac care. METHODS: Publications relating to national cardiac registries across six cardiac subspecialty domains were identified by searching MEDLINE and the Google advanced search function with 26 438 citations and 4812 full-text articles reviewed. RESULTS: A total of 155 registries, representing 49 countries, were included in the study. Of these, 45 related to coronary disease or percutaneous coronary intervention, 28 related to devices, arrhythmia, and electrophysiology, 24 related to heart failure, transplant, and mechanical support, 21 related to structural heart disease, 21 related to congenital heart disease, and 16 related to cardiac surgery. Enrollment was procedure-based in 60% and disease-based in 40%. A total of 73.10 million patients were estimated to have been enrolled in cardiac registries. Quality scoring was performed using a validated registry grading system, with registries performing best in the use of explicit variable definitions and worst in assessment of data reliability. Higher quality scores were associated with government funding, mandated enrollment, linkage to other registries, and outcome risk adjustment. Quality scores and number of registries within a country were positively correlated with each other and with measures of national economic output, health expenditure, and urbanization. CONCLUSIONS: There has been remarkable growth in the uptake of national cardiac registries across the last few decades. However, the quality of processes used to ensure data completeness and accuracy remain variable and few countries have integrated registries covering multiple su

OBJECTIVES: To perform a systematic review and meta-analysis of the literature to understand the variation in the reporting of neuroendocrine staining and determine the influence of reporting neuroendocrine staining at diagnosis on patient outcomes. METHODS: Medical databases were searched to identify studies in which adenocarcinoma specimens were stained with any of the following four neuroendocrine markers: chromogranin A (CgA), neuron-specific enolase (NSE), synaptophysin and CD56. The prevalence of neuroendocrine staining and correlation of the prevalence of neuroendocrine staining to patient outcomes were analysed using a random-effects model. All statistical tests were two-sided. RESULTS: Sixty-two studies spanning 7616 patients were analysed. The pooled prevalence for the most common marker, CgA (41%), was similar to that of NSE (39%) and higher than that of synaptophysin (31%). The prevalence of CgA staining was significantly influenced by reporting criteria, where objective thresholds reduced the variation in prevalence to 26%. No correlation was found between CgA prevalence and tumour grade. Patients positive for CgA staining using objective criteria had more rapid biochemical progression (hazard ratio [HR] 1.98, 95% confidence interval [CI] 1.49 to 2.65) and poorer prostate cancer-specific survival (HR 7.03, 95% CI 2.55 to 19.39) compared to negative patients, even among those with low-risk cancers. CONCLUSION: Discrepancies in the reported prevalence of neuroendocrine cells in adenocarcinoma are driven by the inconsistent scoring criteria. This study unequivocally demonstrates that when neuroendocrine cell staining is assessed with objective criteria it identifies patients with poor clinical outcomes. Future studies are needed to determine the exact quantifiable thresholds for use in reporting neuroendocrine cell staining to identify patients at higher risk of progression.

BACKGROUND: Accurate pre-operative imaging plays a vital role in patient selection for surgery and in allocating stage-appropriate therapies to patients diagnosed with pancreatic cancer (PC). This study aims to: (1) understand the current diagnosis and staging practices for PC; and (2) explore the factors (barriers and enablers) that influence the use of a pancreatic protocol computed tomography (PPCT) or magnetic resonance imaging (MRI) to confirm diagnosis and/or accurately stage PC. METHODS: Semi-structured interviews were conducted with radiologists, surgeons, gastroenterologists, medical and radiation oncologists from the states of New South Wales (NSW) and Victoria, Australia. Interviews were conducted either in person or via video conferencing. All interviews were recorded, transcribed verbatim, de-identified and data were thematically coded according to the 12 domains explored within the Theoretical Domains Framework (TDF). Common belief statements were generated to compare the variation between participant responses. FINDINGS: In total, 21 clinicians (5 radiologists, 10 surgeons, 2 gastroenterologists, 4 medical and radiation oncologists) were interviewed over a four-month-period. Belief statements relevant to the TDF domains were generated. Across the 11 relevant domains, 20 themes and 30 specific beliefs were identified. All TDF domains, with the exception of social influences were identified by participants as relevant to protocol-based imaging using either a PPCT or MRI, with the domains of knowledge, skills and environmental context and resources being offered by most participants as being relevant in influencing their decisions. CONCLUSIONS: To maximise outcomes and personalise therapy it is imperative that diagnosis and staging investigations using the most appropriate imaging modalities are conducted in a timely, efficient and effective manner. The results provide an understanding of specialists' opinion and behaviour in relation to a PPCT or MRI an

Purpose The Upper Gastrointestinal Cancer Registry (UGICR) was developed to monitor and improve the quality of care provided to patients with upper gastrointestinal cancers in Australia. Participants It supports four cancer modules: Pancreatic, oesophagogastric, biliary and primary liver cancer. The pancreatic cancer (PC) module was the first module to be implemented, with others being established in a staged approach. Individuals are recruited to the registry if they are aged 18 years or older, have received care for their cancer at a participating public/private hospital or private clinic in Australia and do not opt out of participation. Findings to date The UGICR is governed by a multidisciplinary steering committee that provides clinical governance and oversees clinical working parties. The role of the working parties is to develop quality indicators based on best practice for each registry module, develop the minimum datasets and provide guidance in analysing and reporting of results. Data are captured from existing data sources (population-based cancer incidence registries, pathology databases and hospital-coded data) and manually from clinical records. Data collectors directly enter information into a secure web-based Research Electronic Data Capture (REDCap) data collection platform. The PC module began with a pilot phase, and subsequently, we used a formal modified Delphi consensus process to establish a core set of quality indicators for PC. The second module developed was the oesophagogastric cancer (OGC) module. Results of the 1 year pilot phases for PC and OGC modules are included in this cohort profile. Future plans The UGICR will provide regular reports of risk-adjusted, benchmarked performance on a range of quality indicators that will highlight variations in care and clinical outcomes at a health service level. The registry has also been developed with the view to collect patient-reported outcomes (PROs), which will further add to our understanding

© 2018 Background: Best practise care optimises survival and quality of life in patients with pancreatic cancer (PC), but there is evidence of variability in management and suboptimal care for some patients. Monitoring practise is necessary to underpin improvement initiatives. We aimed to develop a core set of quality indicators that measure quality of care across the disease trajectory. Methods: A modified, three-round Delphi survey was performed among experts with wide experience in PC care across three states in Australia. A total of 107 potential quality indicators were identified from the literature and divided into five areas: diagnosis and staging, surgery, other treatment, patient management and outcomes. A further six indicators were added by the panel, increasing potential quality indicators to 113. Rated on a scale of 1–9, indicators with high median importance and feasibility (score 7–9) and low disagreement (<1) were considered in the candidate set. Results: From 113 potential quality indicators, 34 indicators met the inclusion criteria and 27 (7 diagnosis and staging, 5 surgical, 4 other treatment, 5 patient management, 6 outcome) were included in the final set. Conclusions: The developed indicator set can be applied as a tool for internal quality improvement, comparative quality reporting, public reporting and research in PC care.

Prevention of cancer-associated thromboembolism (TE) remains a significant clinical challenge and priority world-wide safety initiative. In this prospective non-small cell lung cancer (NSCLC) cohort, longitudinal TE risk profiling (clinical and biomarker) was undertaken to develop risk stratification models for targeted TE prevention. These were compared with published models from Khorana, CATS, PROTECHT, CONKO, and CATS/MICA. The NSCLC cohort of 129 patients, median follow-up 22.0 months (range 5.6-31.3), demonstrated a hypercoagulable profile in >75% patients and TE incidence of 19%. High TE risk patients were those receiving chemotherapy with baseline fibrinogen ≥ 4 g/L and d-dimer ≥ 0.5 mg/L; or baseline d-dimer ≥ 1.5 mg/L; or month 1 d-dimer ≥ 1.5 mg/L. The model predicted TE with 100% sensitivity and 34% specificity (c-index 0.67), with TE incidence 27% vs. 0% for high vs. low-risk. A comparison using the Khorana, PROTECHT, and CONKO methods were not discriminatory; TE incidence 17⁻25% vs. 14⁻19% for high vs. low-risk (c-index 0.51⁻0.59). Continuous d-dimer (CATS/MICA model) was also not predictive of TE. Independent of tumour stage, high TE risk was associated with cancer progression (HR 1.9, p = 0.01) and mortality (HR 2.2, p = 0.02). The model was tested for scalability in a prospective gastrointestinal cancer cohort with equipotency demonstrated; 80% sensitivity and 39% specificity. This proposed TE risk prediction model is simple, practical, potent and can be used in the clinic for real-time, decision-making for targeted thromboprophylaxis. Validation in a multicentre randomised interventional study is underway (ACTRN12618000811202).

OBJECTIVES: To summarise and evaluate evidence from men who had not been diagnosed with prostate cancer about their perspectives on prostate care and prostate cancer. DESIGN: A systematic review of qualitative research, on the perspectives of non-cancerous men regarding prostate cancer prevention and care. SETTING: A wide range of settings including primary and secondary care. PARTICIPANTS: Men from varied demographic backgrounds ranging between 40 to 80 years of age. DATA SOURCES: Three databases (Ovid MEDLINE, Informit, PsychInfo) and Google Scholar were searched for peer-reviewed papers in English reporting research using qualitative methods (in-depth or semistructured interviews and focus groups). REVIEW METHODS: Thematic analysis using inductive and deductive codes. Thematic synthesis was achieved through iterative open, axial and thematic coding. RESULTS: Eight papers (reporting seven studies conducted in Australia, UK and Germany) met inclusion criteria. Four major themes were identified: understanding prostate cancer, masculinity and prostate cancer, barriers to prostate healthcare and managing prostate health. It was reported that men often did not understand screening, prostate anatomy or their prostate cancer risk, and that concerns about masculinity could deter men from seeking health checks. There was evidence of a need to improve doctor-patient communication about case finding. CONCLUSION: Further investigation is required to identify and understand any differences in the perspectives and experiences of men who have not been diagnosed with prostate cancer in metropolitan and regional areas, especially where there may be variations in access to healthcare.

Two common goals for restoration are rapid plant establishment and long-term plant persistence. The success of transplanted populations may be jeopardized if the donor transplants are not genetically diverse, and/or poorly matched to their new environment. Here, we test the effects of local adaptation and plot-level genetic diversity on the early establishment phase of a threatened seagrass species, Posidonia australis, by performing a reciprocal transplant experiment across two genetically and geographically distinct populations in southeastern Australia. Posidonia australis is a long-lived, slow-growing species that has no seed bank, and the successful transplantation of live shoots and seedlings is the only available restoration method. Our results show a strong effect of local adaptation and genetic diversity on P. australis survivorship and performance over the first 6 months following transplantation. High-genetic diversity plots displayed higher survival rates and exhibited reduced productivity and increased carbohydrate reserves within the rhizome. This suggests that high-diversity plots included shoots that were conserving energy stores by actively reducing growth rates during the early stages of transplantation. The lowest diversity plots exhibited high leaf and root productivity and corresponding low carbohydrate reserves. This may be a sign of stress in the low-diversity transplants, potentially explaining the very low survival rate. We suggest that future restoration efforts source donor transplants from multiple local sources to ensure both local adaptation and sufficient genetic diversity to increase the likelihood of early establishment success.

AIM: This study aims to assess characteristics of patients with prostate cancer for whom clinical T stage category (cT) was not documented in the medical record and assess whether specialists had concordant conclusions regarding cT based on digital rectal examination (DRE) notes. METHODS: Data from the Prostate Cancer Outcome Registry - Victoria (PCOR-Vic) were interrogated. Four specialists independently assigned cT to DRE notes. Words, or part thereof, associated with agreement between clinicians were identified. RESULTS: Of the 10 587 men, cT was documented in 8758 (82.7%) cases. Multivariate analysis indicated that poor cT documentation was associated with older patient age (odds ratio [OR] 0.80, 95% confidence interval [CI] 0.66-0.99 if 75.1-85 years; OR 0.50, 95%CI 0.36-0.72 if >85 years); diagnosis via transperineal compared to transrectal ultrasound-guided biopsy (TRUS) (OR 0.68, 95%CI 0.51-0.91); diagnosed in a private hospital (OR 0.85, 95%CI 0.75-0.96); and a diagnostic Gleason score of >8 compared to ≤6 (OR 0.59, 95%CI = 0.48-0.73). cT was more likely documented in men diagnosed via transurethral resection of prostate (OR 2.06, 95%CI 1.64-2.58) compared to TRUS and/or if receiving treatment in a radiotherapy center (OR 3.44, 95%CI 2.80-4.23 for external beam radiotherapy; OR 3.57 95%CI 2.44-5.23 for brachytherapy and OR 1.34, 95%CI 1.06-1.69 for combination surgery and radiotherapy) compared to those undergoing radical prostatectomy. Agreement in cT assignment ranged from kappa of 0.158 to 0.582. Stem word components in DRE notes associated with poorest level of agreement were "abnorm," "hard," "nodul" and those with highest level of agreement were terms "benign" and "smooth." CONCLUSIONS: Mode of diagnosis/subsequent treatment, and cancer characteristics were associated with cT documentation. Third party interpretation of clinical notes is problematic.

OBJECTIVE: To inform the development of a patient-reported outcome measure, the aim of this study was to identify which symptoms and feelings following percutaneous coronary intervention (PCI) are most important to patients. DESIGN: Discrete-choice experiment consisting of two hypothetical scenarios of 10 symptoms and feelings (pain or discomfort; shortness of breath; concern/worry about heart problems; tiredness; confidence to do usual activities; ability to do usual activities; happiness; sleep disturbance; dizziness or light-headedness and bruising) experienced after PCI, described by three levels (never, some of the time, most of the time). Preference weights were estimated using a conditional logit model. SETTING: Four Australian public hospitals that contribute to the Victorian Cardiac Outcomes Registry (VCOR) and a private insurer's claim database. PARTICIPANTS: 138 people aged >18 years who had undergone a PCI in the previous 6 months. MAIN OUTCOME MEASURES: Patient preferences via trade-offs between 10 feelings and symptoms. RESULTS: Of the 138 individuals recruited, 129 (93%) completed all 16 choice sets. Conditional logit parameter estimates were mostly monotonic (eg, moving to worse levels for each individual symptom and feeling made the option less attractive). When comparing the magnitude of the coefficients (based on the coefficient of the worst level relative to best level in each item), feeling unhappy was the symptom or feeling that most influenced perception of a least-preferred PCI outcome (OR 0.42, 95% CI 0.34 to 0.51, p<0.0001) and the least influential was bruising (OR 0.81, 95% CI 0.67 to 0.99, p=0.04). CONCLUSION: This study provides new insights into how patients value symptoms and feelings they experience following a PCI.

OBJECTIVE: To determine the effects of laparoscopic radical prostatectomy (LRP), or robot-assisted radical prostatectomy (RARP) compared with open radical prostatectomy (ORP) in men with localized prostate cancer. MATERIALS AND METHODS: We performed a comprehensive search using multiple databases (CENTRAL, MEDLINE, EMBASE) and abstract proceedings, with no restrictions on the language of publication or publication status, up until 9 June 2017. We included all randomized or pseudo-randomized controlled trials that directly compared LRP and RARP with ORP. Two review authors independently examined full-text reports, identified relevant studies, assessed the eligibility of studies for inclusion, extracted data and assessed risk of bias. We performed statistical analyses using a random-effects model and assessed the quality of the evidence according to Grading of Recommendations Assessment, Development and Evaluation (GRADE). The primary outcomes were prostate cancer-specific survival, urinary quality of life and sexual quality of life. Secondary outcomes were biochemical recurrence-free survival, overall survival, overall surgical complications, serious postoperative surgical complications, postoperative pain, hospital stay and blood transfusions. RESULTS: We included two unique studies in a total of 446 randomized participants with clinically localized prostate cancer. All available outcome data were short-term (up to 3 months). We found no study that addressed the outcome of prostate cancer-specific survival. Based on one trial, RARP probably results in little to no difference in urinary quality of life (mean difference [MD] -1.30, 95% confidence interval [CI] -4.65 to 2.05; moderate quality of evidence) and sexual quality of life (MD 3.90, 95% CI: -1.84 to 9.64; moderate quality of evidence). No study addressed the outcomes of biochemical recurrence-free survival or overall survival. Based on one trial, RARP may result in little to no difference in overall surgical c

BACKGROUND: The development, monitoring, and reporting of indicator measures that describe standard of care provide the gold standard for assessing quality of care and patient outcomes. Although indicator measures have been reported, little evidence of their use in measuring and benchmarking performance is available. A standard set, defining numerator, denominator, and risk adjustments, will enable global benchmarking of quality of care. OBJECTIVE: To develop a set of indicators to enable assessment and reporting of quality of care for men with localised prostate cancer (PCa). DESIGN, SETTING, AND PARTICIPANTS: Candidate indicators were identified from the literature. An international panel was invited to participate in a modified Delphi process. Teleconferences were held before and after each voting round to provide instruction and to review results. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Panellists were asked to rate each proposed indicator on a Likert scale of 1-9 in a two-round iterative process. Calculations required to report on the endorsed indicators were evaluated and modified to reflect the data capture of the Prostate Cancer Outcomes Registry-Australia and New Zealand (PCOR-ANZ). RESULTS AND LIMITATIONS: A total of 97 candidate indicators were identified, of which 12 were endorsed. The set includes indicators covering pre-, intra-, and post-treatment of PCa care, within the limits of the data captured by PCOR-ANZ. CONCLUSIONS: The 12 endorsed quality measures enable international benchmarking on the quality of care of men with localised PCa. Reporting on these indicators enhances safety and efficacy of treatment, reduces variation in care, and can improve patient outcomes. PATIENT SUMMARY: PCa has the highest incidence of all cancers in men. Early diagnosis and relatively high survival rates mean issues of quality of care and best possible health outcomes for patients are important. This paper identifies 12 important measurable quality indicators

© 2017 John Wiley & Sons Ltd The purpose of this study was to provide in-depth insight into men's experiences of prostate cancer, specifically: perceived stigma and self-blame, social isolation, unmet need and help-seeking. A qualitative descriptive approach was used. Semi-structured interviews were undertaken with 20 men diagnosed with prostate cancer, and thematic analysis was undertaken. Some participants perceived a stigma associated with prostate cancer and cancer in general, which sometimes acted as a barrier to disclosure. Self-blame and internalisation of cause was not a prominent issue. Participants’ descriptions of emotional distress, social isolation and anxiety demonstrated the impact of prostate cancer. Social isolation was most commonly reported as a physical consequence of treatment and/or side effects. Participants felt both support and ongoing care were limited at post-treatment. Most did not seek or receive help for emotional or psychosocial problems from a formal source due to anticipated awkwardness, autonomous coping, not burdening others, unwanted sympathy and retaining privacy. Prostate cancer can cause considerable emotional and social burden for some men, and many are unlikely to seek or receive help. Men, and their support networks, require active encouragement throughout diagnosis, treatment and follow-up to overcome barriers and access additional support, particularly for sexual, emotional and psychosocial issues.

Introduction Advance care planning (ACP) is a process between a person, their family/carer(s) and healthcare providers that supports adults at any age or stage of health in understanding and sharing their personal values, life goals and preferences regarding future medical care. The Australian government funds a number of national initiatives aimed at increasing ACP uptake; however, there is currently no standardised Australian data on formal ACP documentation or self-reported uptake. This makes it difficult to evaluate the impact of ACP initiatives. This study aims to determine the Australian national prevalence of ACP and completion of Advance Care Directives (ACDs) in hospitals, aged care facilities and general practices. It will also explore people’s self-reported use of ACP and views about the process.Methods and analysis Researchers will conduct a national multicentre cross-sectional prevalence study, consisting of a record audit and surveys of people aged 65 years or more in three sectors. From 49 participating Australian organisations, 50 records will be audited (total of 2450 records). People whose records were audited, who speak English and have a decision-making capacity will also be invited to complete a survey. The primary outcome measure will be the number of people who have formal or informal ACP documentation that can be located in records within 15 min. Other outcomes will include demographics, measure of illness and functional capacity, details of ACP documentation (including type of document), location of documentation in the person’s records and whether current clinical care plans are consistent with ACP documentation. People will be surveyed, to measure self-reported interest, uptake and use of ACP/ACDs, and self-reported quality of life.Ethics and dissemination This protocol has been approved by the Austin Health Human Research Ethics Committee (reference HREC/17/Austin/83). Results will be submitted to international peer-reviewed journals and

© 2017 Evans, Vergés and Poore. Seagrasses that are predominantly clonal often have low levels of genetic variation within populations and predicting their response to changing conditions requires an understanding of whether genetic variation confers increased resistance to environmental stressors. A higher level of genetic diversity is assumed to benefit threatened species due to the increased likelihood of those populations having genotypes that can persist under environmental change. To test this idea, we conducted an in situ shading experiment with six geographically distinct meadows of the threatened seagrass Posidonia australis that vary in genetic diversity. Different genotypes within meadows varied widely in their physiological and growth responses to reduced light during a simulated short-term turbidity event. The majority of meadows were resistant to the sudden reduction in light availability, but a small subset of meadows with low genotypic diversity were particularly vulnerable to the early effects of shading, showing substantially reduced growth rates after only 3 weeks. Using the photosynthetic performance (maximum quantum yield) of known genotypes, we simulated meadows of varying genetic diversity to show that higher diversity can increase meadow resilience to stress by ensuring a high probability of including a high-performing genotype. These results support the hypothesis that complementarity among genotypes enhances the adaptive capacity of a population, and have significant implications for the conservation of declining P. australis meadows close to the species range edge on the east coast of Australia, where the genotypic diversity is low.

OBJECTIVES: To establish a Prostate Cancer Outcomes Registry-Australia and New Zealand (PCOR-ANZ) for monitoring outcomes of prostate cancer treatment and care, in a cost-effective manner. MATERIALS AND METHODS: Stakeholders were recruited based on their interest, importance in achieving the monitoring and reporting of clinical practice and patient outcomes, and in amalgamation of existing registries. Each participating jurisdiction is responsible for local governance, site recruitment, data collection, and data transfer into the PCOR-ANZ. To establish each local registry, hospitals and clinicians within a jurisdiction were approached to voluntarily contribute to the registry following relevant ethical approval. Patient contact occurs following notification of prostate cancer through a hospital or pathology report, or from a cancer registry. Patient registration is based on an opt-out model. The PCOR-ANZ is a secure web-based registry adhering to ISO 27001 standards. Based on a standardised minimum data set, information on demographics, diagnosis, treatment, outcomes, and patient reported quality of life, are collected. RESULTS: Eight of nine jurisdictions have agreed to contribute to the PCOR-ANZ. Each jurisdiction has commenced implementation of necessary infrastructure to support rapid rollout. PCOR-ANZ has defined a minimum data set for collection, to enable analysis of key quality indicators that will aid in assessing clinical practice and patient focused outcomes. CONCLUSION: PCOR-ANZ will provide a useful resource of risk-adjusted evidence-based data to clinicians, hospitals, and decision makers on prostate cancer clinical practice.

BACKGROUND: Lung cancer remains a major disease burden in Victoria (Australia) and requires a complex and multidisciplinary approach to ensure optimal care and outcomes. To date, no uniform mechanism is available to capture standardized population-based outcomes and thereby provide benchmarking. The establishment of such a data platform is, therefore, a primary requisite to enable description of process and outcome in lung cancer care and to drive improvement in the quality of care provided to individuals with lung cancer. MATERIALS AND METHODS: A disease quality registry pilot has been established to capture prospective data on all adult patients with clinical or tissue diagnoses of small cell and non-small cell lung cancer. Steering and management committees provide clinical governance and supervise quality indicator selection. Quality indicators were selected following extensive literature review and evaluation of established clinical practice guidelines. A minimum dataset has been established and training and data capture by data collectors is facilitated using a web-based portal. Case ascertainment is established by regular institutional reporting of ICD-10 discharge coding. Recruitment is optimized by provision of opt-out consent. RESULTS: The collection of a standardized minimum data set optimizes capacity for harmonized population-based data capture. Data collection has commenced in a variety of settings reflecting metropolitan and rural, and public, and private health care institutions. The data set provides scope for the construction of a risk-adjusted model for outcomes. A data access policy and a mechanism for escalation policy for outcome outliers has been established. CONCLUSIONS: The Victorian Lung Cancer Registry provides a unique capacity to provide and confirm quality assessment in lung cancer and to drive improvement in quality of care across multidisciplinary stakeholders.

OBJECTIVE: To describe the characteristics of patients with and without positive surgical margins (PSMs) and to analyse the impact of PSMs on secondary cancer treatment after radical prostatectomy (RP), with short-term follow-up. PATIENTS AND METHODS: We analysed data from 2385 consecutive patients treated using RP, who were notified to the Prostate Cancer Registry by 37 hospitals in Victoria, Australia between August 2008 and February 2012. Independent and multivariate models were constructed to predict the likelihood of PSMs. Independent and multivariate predictors of secondary treatment after RP in the initial 12 months after diagnosis were also assessed. RESULTS: Data on PSM status were collected for 2219/2385 (93%) patients. In total 592/2175 (27.2%) RPs resulted in PSMs; 102/534 (19.1%) in the low-risk group, 317/1218 (26.0%) in the intermediate-risk group, 153/387 (39.5%) in the high-risk group, and 9/11 (81.8%) in the very-high-risk disease group of patients. Patients having surgery in a hospital where <10 RPs occur each year were significantly more likely to have a PSM (incidence rate ratio [IRR] 1.44, 95% confidence interval [CI] 1.07-1.93) and those in the intermediate-, high- or very-high-risk groups (IRR 1.34, 95% CI 1.09-1.65, P = 0.007, IRR 1.96, 95% CI 1.57-2.45, P < 0.001 and IRR 3.81, 95% CI 2.60-5.60, P < 0.001, respectively) were significantly more likely to have a PSM than those in the low-risk group (IRR 2.50, 95% CI 1.23-5.11, P = 0.012). Patients with PSMs were significantly less likely to have been treated at a private hospital than a public hospital (IRR 0.76, 95% CI 0.63-0.93, P = 0.006) or to have undergone robot-assisted RP (IRR 0.69, 95% CI 0.55-0.87; P = 0.002) than open RP. Of the 2182 patients who underwent RP in the initial 12 months after diagnosis, 1987 (91.1%) received no subsequent treatment, 123 (5.6%) received radiotherapy, 47 (2.1%) received androgen deprivation therapy (ADT) and 23 (1.1%) received a combination of radiothera

BACKGROUND: The need to improve patient safety has been identified as a major priority for health reform in developed countries, including Australia. We investigated the implementation and appropriateness of Variable Life Adjusted Displays as a quality control procedure to monitor "in-control" versus "out-of-control" processes in Victorian public hospitals. METHODS: Victorian Admitted Episode Data from Department of Human Services, Victoria for 2004-7 were used. The VLAD is a plot of a cumulative sum of the difference in expected outcome (range 0-1) and observed outcome (0 or 1) for sequential separations. Three outcomes were assessed: in-hospital mortality for acute myocardial infarction, stroke and heart failure. Logistic regression was used to obtain a realistic measure of expected mortality over the period 2004-5, adjusting for covariates and comorbidities, to estimate expected mortality risk for the separations between 2005-7. VLAD were plotted for the years 2005-7, by the 11 hospitals with the highest frequency of separations. Signalling limits for 30%, 50% and 75% risk decrease and risk increase were determined and plotted for each VLAD utilizing risk-adjusted cumulative sum techniques. This is a likelihood-ratio test statistic for signalling. If the VLAD signalled by intersecting with a limit, the limit was reset. RESULTS: The three logit models displayed reasonable fit to the observed data. There were n = 2999 separations in the AMI model, n = 3598 in the HF model and n = 1922 in the stroke model. The number of separations plotted by VLAD ranged from n = 126 to n = 648. No signals were observed in 64%, 55% and 18% of VLAD for AMI, HF and stroke respectively. For AMI and HF 9% of hospitals signalled at least once for each of 30%, 50% and 75% risk increase, whereas this was 45% for stroke. Hospitals signalling at least once for risk decrease ranged from 18% to 36% across the levels of risk and outcomes. No VLAD signalled for both risk decrease and increase. C
