Despite the burden of venous thromboembolism (VTE) among surgical patients on health systems in Australia, data on VTE incidence and its variation within Australia are lacking. We aim to explore VTE and subsequent mortality rates, trends and variations across Australian acute public hospitals. A large retrospective cohort study using all elective surgical patients in 82 acute public hospitals during 2002-2009 in New South Wales, Australia. Patients underwent elective surgery within 2 days of admission, aged between 18 and 90 years, and who were not transferred to another acute care facility; 4 362 624 patients were included. VTE incidents were identified by secondary diagnostic codes. Poisson mixed models were used to derive adjusted incidence rates and rate ratios (IRR). 2/1000 patients developed postoperative VTE. VTE increased by 30% (IRR=1.30, CI 1.19 to 1.42) over the study period. Differences in the VTE rates, trends between hospital peer groups and between hospitals with the ...

Community, or non-professional, rugby has a high incidence of mild traumatic brain injury (mTBI). Risk of further mTBI, or long term consequences of repeat mTBI, is an emerging public health issue. To identify the time to recurrent mTBI and key predictors for time to recurrent mTBI among community rugby players. Prospective cohort study. Rugby union players from Sydney, Australia playing in grade, suburban and school-level community competitions. A cohort of 3 207 male players was recruited pre-season and followed between one and three playing seasons. Demographic information, player characteristics and concussion history was collected. Players sustaining an mTBI were recorded and information pertaining to the injury, recovery and return-to-play was collected over three months. Loss of consciousness and post-traumatic amnesia. Time to mTBI, namely, the number of hours of game exposure played up to the time the player sustained a first and repeat mTBI. Players were more likely to sus...

Aim: To compare rates of past reported traumatic brain injury (TBI) in a prisoner sample with those in a control group drawn from the same location of usual residence.
Method: The prisoner group comprised a consecutive sample of men (n 1⁄4 200) received into custody and screened by face- to-face interview. The control group comprised men (n1⁄4200) matched for location of usual residence screened by telephone interview. Participants were asked about past TBIs and screened for drug and alcohol abuse, impulsivity and dissocial personality disorder.
Results: Eighty-two per cent of prisoners and 71.5% of community participants reported at least one past TBI of any severity (i.e. with or without a loss of consciousness (LOC)) and 64.5% of prisoners and 32.2% of community participants reported at least one TBI associated with a LOC. Prisoners were more likely to report persisting side-effects of TBI and were much more likely to screen positive for impulsivity and dissocial personality disorder. Multivariate analyses found no significant association between TBI frequency or severity and custody/community group membership.
Conclusions: High reported rates of TBI in prisoner populations may reflect the excess of socio-demographic risk factors for TBI. Results of the current study do not support a role for TBI as causally related to criminal conduct.
