Patients injured at work are more likely to commence litigation and develop symptoms consistent with posttraumatic stress disorder. Nonreturn to work is associated with higher psychosocial morbidity. Return to work is predicted from event and recovery period variables.

Objectives: To determine the prevalence of post-trauma psychological problems among a cohort of male accident and emergency department patients admitted to hospital. To identify the changes in their psychological symptoms over an 18 month follow up period. Methods: A prospective cohort study of male accident and emergency department patients who were admitted for treatment of an injury. Baseline interview recorded demographic details and accident details. Standardised questionnaires measured baseline psychological state and personality type. Follow up at six weeks, six months, and 18 months after injury was by face to face interview or postal questionnaire and recorded progress since injury, and documented psychological status through the use of standardised questionnaires to detect psychiatric disorder and symptoms of post-traumatic stress disorder (PTSD). Results: 210 male patients were recruited into the study. Psychiatric disorder was identified in 47.6% of responders at six weeks, and 43.4% at six months after injury. This improved significantly at 18 months. PTSD symptoms were moderate in 25%-30% and severe in 5%-14% and did not change significantly over the study period. A significant relation was found between previous psychiatric history and psychological symptoms at 18 months after injury. No relation was identified between injury severity and psychological status after injury. Conclusion: This study finds a high prevalence of psychological distress in male accident and emergency department patients after injury. Although some symptoms resolve over the follow up period, a proportion remain and may be related to previous psychiatric history. There was no relation identified between severity of injury and psychological morbidity.

The intravenous drug use behaviour and HIV risk reduction strategies used by a group of Scottish inmates prior to prison, during imprisonment and as expected after release was investigated. From a sample of 559 inmates (480 males and 79 females) 27.5% were involved in IVDU prior to imprisonment, 7.7% on at least one occasion during a period of imprisonment and 14.7% expected to do so after release. Prior to imprisonment 17.3% had shared needles, 5.7% at some time during imprisonment and 4.3% expected to do so after release. Some form of HIV risk reduction strategies were practised by the majority of IVDU inmates prior to imprisonment, during imprisonment and were expected to continue after release. The most at risk inmates were those who continued to share injecting equipment without reduction and without sterilizing. The reduction in IVDU and needle sharing during imprisonment in comparison to prior to imprisonment was paralleled by a self-perceived reduction of personal risk from HIV during imprisonment.

Purpose. To determine diagnostic accuracy of kinetic visual field assessment by Octopus 900 perimetry compared with Goldmann perimetry. Methods. Prospective cross section evaluation of 40 control subjects with full visual fields and 50 patients with known visual field loss. Comparison of test duration and area measurement of isopters for Octopus 3, 5, and 10°/sec stimulus speeds. Comparison of test duration and type of visual field classification for Octopus versus Goldmann perimetry. Results were independently graded for presence/absence of field defect and for type and location of defect. Statistical evaluation comprised of ANOVA and paired t test for evaluation of parametric data with Bonferroni adjustment. Bland Altman and Kappa tests were used for measurement of agreement between data. Results. Octopus 5°/sec perimetry had comparable test duration to Goldmann perimetry. Octopus perimetry reliably detected type and location of visual field loss with visual fields matched to Goldmann results in 88.8% of results (K = 0.775). Conclusions. Kinetic perimetry requires individual tailoring to ensure accuracy. Octopus perimetry was reproducible for presence/absence of visual field defect. Our screening protocol when using Octopus perimetry is 5°/sec for determining boundaries of peripheral isopters and 3°/sec for blind spot mapping with further evaluation of area of field loss for defect depth and size.

Factors identifying individuals at-risk from psychological distress following injury include those related to the immediate response and the recovery phases of injury. Further development is needed to convert identified predictors into a comprehensive screening tool for clinical use.
