Background: The postpartum haemorrhage (PPH) rate in Victoria in 2009 for women having their first birth, based on information reported to the Victorian Perinatal Data Collection (VPDC), was 23.6% (primiparas). Prior to 2009 PPH was collected via a tick box item on the perinatal form. Estimated blood loss (EBL) volume is now collected and it is from this item the PPH rate is calculated. Periodic assessment of data accuracy is essential to inform clinicians and others who rely on these data of their quality and limitations. Aims: This paper describes the results of a state‐wide validation study of the accuracy of EBL volume and EBL‐related data items reported to VPDC. Materials and methods: PPH data from a random sample of 1% of births in Victoria in 2011 were extracted from source medical records and compared with information submitted to the VPDC. Accuracy was determined, together with sensitivity, specificity, positive predictive value and negative predictive value for dichotomous items. Results: Accuracy of reporting for EBL ≥ 500 mL was 97.2% and for EBL ≥ 1500 mL was 99.7%. Sensitivity for EBL ≥ 500 mL was 89.0% (CI 83.1‐93.0) and for EBL ≥ 1500 mL was 71.4% (CI 35.9–91.8). Blood product transfusion, peripartum hysterectomy and procedures to control bleeding were all accurately reported in >99% of cases. Conclusions: Most PPH‐related data items in the 2011 VPDC may be considered reliable. Our results suggest EBL ≥ 1500 mL is likely to be under‐reported. Changes to policies and practices of recording blood loss could further increase accuracy of reporting. [ABSTRACT FROM AUTHOR]

Objective To examine urban-rural differences and individual risk factors for a late stage of breast cancer at diagnosis in Australian women. Design Individual-level longitudinal data were linked with cancer registry data from New South Wales (New South Wales Cancer Registry linked by the Centre for Health Record Linkage (CHeReL)), Queensland (Queensland Cancer Registry) and Victoria (The Cancer Council Victoria). Setting Participants were drawn from the Australian Longitudinal Study on Women's Health 1946-1951 cohort (n = 13 715). Participants The sample included 195 women identified from the linked cancer registry data with a breast cancer diagnosis. Interventions Rural or urban residence was measured using Accessibility/Remoteness Index of Australia Plus (ARIA+). Individual characteristics and socio-demographic variables examined included survey year, menopausal status, country of birth, education and marital status. Main outcome measures A late stage of breast cancer at diagnosis was defined based on the TNM Classification of Malignant Tumours. Results A late stage of breast cancer diagnosis was observed in 36% of women residing in urban areas and 40% of women residing in rural areas. After adjusting for individual characteristics, we found that obesity was the strongest risk factor for a late stage of breast cancer at diagnosis. Conclusions Given that women are becoming increasingly obese, and that the rate of obesity is higher in the Australian rural population, this paper provides further evidence for targeting interventions for obesity, particularly in rural Australia, as a public health priority.

Objective This paper aims to describe cancer survival and examine association between survival and socio-demographic characteristics across Barwon South- Western region ( BSWR) in Victoria, Australia. Design This study is based on the retrospective cohort database of patients accessing oncology services across BSWR. Setting Six rural and three urban hospital settings across the BSWR. Participants The participants were patients who were diagnosed with cancer in 2009. Main outcome measures Overall survival (OS) of participants was the main outcome measure. Results Total of 1778 eligible patients had four-year OS for all cancers combined of 59.7% (95% CI, 57.4-62.0). Improved OS was observed for patients in the upper socio-economic tertile (64.2%; 95% CI, 60.9-67.5) compared to the middle (59.3%; 95% CI, 55.5-63.1) and lowest tertiles (49.6%; 95% CI, 44.2-54.9) ( P < 0.01). On multivariate analyses, higher socio-economic status remained a significant predictor of OS adjusting for gender, remoteness and age ( HR [hazard ratio] 0.81; 95% CI 0.74-0.89; P < 0.01). Remoteness was significantly associated with improved OS after adjusting for age, gender and socio-economic status ( HR 0.86; 95% CI, 0.77-0.97; P = 0.01). Older age ≥70 years compared to <70 years conferred inferior OS ( HR 3.08; 95% CI, 2.64-3.59; P < 0.01). Conclusions Our study confirmed improved survival outcomes for patients of higher socio-economic status and younger age. Future research to explain the unexpected survival benefit in patients who lived in more remote areas should examine factors including the correlation between geographical residence and eventual treatment facility as well as compare the BSWR care model to other regions' approaches.

ABSTRACT Aims This paper examined whether or not: (a) care-giver 'alcohol abuse' is associated with recurrent child maltreatment; (b) other 'risk factors' affect this relationship; and (c) which of alcohol abuse or other drug abuse plays a stronger role. It also examined (d) how children and families where alcohol-related child abuse was identified were managed by child protection services (CPS) in Victoria, Australia. Design, setting and participants Using anonymized data from Victorian CPS, repeat cases were examined involving 29 455 children identified between 2001 and 2005. Measurements Carer alcohol abuse, other drug abuse, mental ill-health, carer experience of abuse as a child, child age and gender, family type, socio-economic variables and level of child protection service intervention as recorded in the CPS electronic database were examined as risk factors for recurrence, using bivariate and multivariate techniques. Findings Almost one-quarter of children in CPS experienced a recurrent incident of child maltreatment in a 5-year period. Where carer alcohol abuse was identified children were significantly more likely to experience multiple incidents compared with children where this was not identified ( P < 0.001), as were children where other family risk factors (including markers of socio-economic disadvantage) were identified. The majority of children whose carers were identified with alcohol abuse experienced either repeat incidents or interventions (84%), although almost three-quarters of these children were managed without resort to the most serious outcome, involving court orders. Conclusions Alcohol and drug abuse in carers are important risk-factors for recurrent child maltreatment after accounting for other known risk factors; the increased risk appears to be similar between alcohol and drug abuse.

Background and Purpose The purpose of this paper was to determine if the Six-minute Walk Test (6MWT) was a reliable exercise test for patients referred to cardiac rehabilitation when up to three tests were performed and to determine if test scores differed according to between-test time interval. Methods Thirty adults aged 63 ± 7.9 years referred to cardiac rehabilitation participated in a repeated measures reliability trial. Participants completed three 6MWTs within a one-week period. Participants were randomly allocated to one of three groups: on the first day, Group A completed three walks, Group B completed two walks and Group C completed one walk. Relative reliability was expressed in a ratio (ICC2,1), and absolute reliability was expressed in metres (95% confidence intervals) for group and individuals. Results The 6MWT demonstrated a high level of relative reliability (intraclass correlation coefficients [ICC] = 0.94) across the three walks. There was no statistically significant difference between the test scores of the three groups. However, there was an increase in distance walked from the first to the second to the third 6MWT. Absolute reliability indicated that a change of at least 44 m would be required to be interpreted as true change in a group, and at least 95 m to be interpreted as true change in an individual with 95% confidence. Conclusion Three 6MWTs completed in relatively short timeframes were not sufficient for reliable results as there was an increase in the distance walked, and relatively large increases in distances would be required to be interpreted as change. It did not make any difference whether the tests were all completed on one day or over one week. This study highlighted problems that may arise when relying on reliability coefficients alone to interpret reliability. These results suggest that the 6MWT may not have sufficient reliability to be a suitable test to evaluate exercise tolerance in patients referred to cardiac rehabilitation.
