The epidemiology of disability and occupation handicap resulting from major traumatic injury.

PURPOSE: To assess the prevalence of disability and handicap among survivors of major traumatic injury (injury severity score > 15) using a prospective population based cohort study design. The study was set in the former Yorkshire Health Region. SUBJECTS/METHODS: A cohort of 367 individuals identified as having received and survived major traumatic injury during the 12 month period October 1988-September 1989. OPCS disability scores and employment status at 5 years post injury were established through structured face-to-face interviews. RESULTS: Three hundred and four (84% response. 89% adjusted response) individuals were interviewed. Seventy-seven percent of these were male and they had a mean age (SEM) of 30.8 (1.06) years. Injuries were caused by road traffic accidents in 68% of the cases and were primarily orthopaedic and neurological in nature. At 5 years post injury 81.2% of individuals had some form of measurable disability principally relating to locomotion, behaviour, continence and intellectual functioning consistent with injury type. A third had an OPCS disability score of 5 or greater and approximately 1 in 12 were in the most severe categories of OPCS scores of 9-10 necessitating dependency on formal or informal carer assistance. Whilst five of the eight sub-scales of the SF36 showed correlation in severity proportion, general health perception and energy/vitality were higher in those with increasing disability as measured by the OPCS scale. Of those between the ages of 16-64 nearly half (49%) were not in paid employment at the time of follow up. CONCLUSION: A high prevalence of severe permanent disability, work disability and occupation handicap has been identified in a cohort of mainly young adult males following major traumatic injury resulting from road traffic accidents. Progress in accident prevention, injury reduction and the management of patients with serious injuries should be measured not only in terms of reduced mortality from such events but also in the long term disability and quality of life sequelea of survivors.

Positive association between self-reported fatty food consumption and factor VII coagulant activity, a risk factor for coronary heart disease, in 4246 middle-aged men.

Raised levels of factor VII coagulant activity (VIIc) have been reported to increase the incidence of CHD. Preliminary evidence from observational and experimental studies suggests that dietary fat intake is positively associated with VIIc. We explored this further in 4,246 men aged 45-69, who were found to be free of major CHD when screened for a primary prevention trial of antithrombotic medication. All men were asked about their consumption of fatty foods and changes in consumption in the last month. In the 9% of men who reported avoidance of fatty foods in the month before interview, age adjusted VIIc was 7.8% of standard (95% CI 5.1-10.6%) lower than in the remainder. Serum cholesterol and body mass index (BMI) were also significantly lower. The extent to which fat consumed in the past month had deviated from usual intake was significantly and positively related with VIIc, serum cholesterol and BMI. Thus, the VIIc difference between those eating much less fatty food than usual and those eating much more than usual was 11% of standard, with those eating their usual amount having an intermediate level. This study adds to the evidence that dietary fat intake influences VIIc and coagulability. The effect is rapid, so that much of the benefit of dietary fat reduction on thrombogenic risk in CHD is likely to occur within a short time. Thus, the results reinforce the value of a low fat diet, even in individuals with advanced atheroma, in whom dietary intervention has sometimes been considered unlikely to be effective.

The problems of monitoring tuberculosis in an inner-city health district: integrated information is required.

This paper discusses the difficulties in monitoring tuberculosis in an inner-city district health authority. Tuberculosis incidence was reviewed between 1981 and 1989 using several data sources: statutory notifications, hospital activity analysis, death certificates and chest clinic records. The overall notification rate declined but remained higher than national rates; the age-sex distribution was similar to national studies. However, interpretation was limited by the problems of small numbers, the difficulty in obtaining reliable numerator and denominator estimates of ethnic groups, the limited data available about sub-groups of concern such as the homeless, and finally by the incompleteness of the data. Improved methods of data linkage are required to facilitate more complete ascertainment and validation of the diagnosis.

Strenuous exercise, plasma fibrinogen, and factor VII activity.

OBJECTIVE: To assess the effect of physical activity on plasma fibrinogen and factor VII activity and thus on the risk of ischaemic heart disease. DESIGN: Cross sectional survey. SETTING: Ten group practices in the Medical Research Council's General Practice Research Framework. PATIENTS: 3967 men aged 45-69 attending screening clinics for the thrombosis prevention trial. METHODS: Structured interview to elicit the intensity and frequency of physical exercise during past month. Measurement of fibrinogen, factor VII activity, cholesterol concentration, blood pressure, and other indices of ischaemic heart disease risk. RESULTS: Strenuous exercise was associated with significantly lower fibrinogen concentrations than mild exercise, implying a difference of about 15% in the risk of ischaemic heart disease. Strenuous exercise was also associated with lower cholesterol concentrations. More frequent strenuous exercise was associated with lower factor VII activity. CONCLUSIONS: With the recognition of plasma fibrinogen as a strong index of ischaemic heart disease risk the results of this and other studies suggest a pathway through which the protective effect of strenuous exercise may partly be mediated and they provide doctors and patients with a valuable incentive towards prevention, particularly in those whose risk of ischaemic heart disease is substantially due to raised fibrinogen concentrations.
