The Canadian Agricultural Injury Surveillance Program: a new injury control initiative.

The Canadian Agricultural Injury Surveillance Program (CAISP) is a national system, established in 1996, for monitoring injuries among the agricultural community. The program involves ongoing collection, analysis, interpretation and dissemination of injury data. These data are an important tool for the development and evaluation of Canadian farm safety programs. The ultimate goal of the program is to enhance the health and safety of Canadian farm workers and their families through preventive measures based upon a better understanding of the occurrence of farm injuries. This report provides a brief history of the surveillance system; a description of the program in terms of its objectives and the methods used for case identification and data collection; an overview of products from the initiative; and a discussion of some of the challenges encountered in developing a national surveillance system.

Hospital costs associated with agricultural machinery injuries in Ontario.

To assist those responsible for agricultural safety, we: (1) piloted an approach to costing hospitalized farm injuries; and, (2) described ambulance and inpatient costs associated with these injuries in Ontario. Hospital discharge records (hospital separations) for farm machinery injuries in Ontario (n = 1,610) were identified by ICD9-CM E-codes for 1985-1993. Ambulance costs were estimated by the Ontario Ministry of Health. For each case, the hospital costs were calculated by multiplying the case-specific resource intensity weight by the average inpatient cost per weighted case. The costs (1993 Canadian dollars) ranged from $768 to $62,643 and totaled $6.9 million over the study period. Males accounted for 89.8% of the total costs. Tractor injuries accounted for a large proportion of costs (34.3%). The median costs per case varied by type of machinery, ranging from $2,043 for ploughs/disks to $3,366 for augers. Entanglement injuries were responsible for the largest proportion of costs (40.7%), while tractor rollovers accounted for the highest median cost ($3,065). Although these figures represent a fraction of the total costs associated with farm injuries, the results provide one basis from which to justify and target preventive initiatives. This approach to costing may also be widely applicable to other health issues.

A population-based study of hospitalized injuries in Kingston, Ontario, identified via the Canadian Hospitals Injury Reporting and Prevention Program.

This report uses data from the Kingston and Region Injury Surveillance Program (KRISP), a subset of the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), to describe rates and identify patterns of hospitalized injury in Kingston and area. During 1994 and 1995, there were 998 reported hospitalizations for injury, resulting in an overall rate of 30.0 injuries per 10,000 per year (males: 30.3 per 10,000; females: 29.7 per 10,000). Major patterns of hospitalized injury were identified as priorities for intervention: 1) falls in all age groups, but especially those in children, and falls leading to hip and pelvic fractures among older adults, the majority of which occurred in residential settings; 2) motor vehicle and other transport injuries (e.g. motorcycle injuries) in all age groups; and 3) intentional injuries (e.g. fights) among males aged 20 64 years. Discussion focuses on the use of the surveillance system to set priorities for prevention and further research within this population.

The effect of the tricyclic antidepressant drug, nortriptyline on left ventricular ejection fraction and left ventricular volumes.

Eight patients with major depression but otherwise healthy underwent radionuclide cardiography before and during nortriptyline treatment. The second examination was performed when the nortriptyline plasma concentration was within the therapeutic range (60-150 micrograms X l-1). Heart rate, arterial blood pressure, left ventricular ejection fraction, left ventricular volumes, systolic pressure-volume ratio, and cardiac output were determined. Heart rate increased in mean by 13% (P less than 0.05). All other variables were unchanged. We conclude that nortriptyline in therapeutic doses produces no major adverse effect on left ventricular function. Routine radionuclide cardiography might be a suitable method to detect among those treated with tricyclic antidepressants the occasional susceptible patient. This may particularly apply to patients with known heart disease and to elderly patients.

Nicholson score for prescribing digoxin compared with Jellife nomogram.

A series of 84 medical inpatients were treated in random order with oral digoxin in doses calculated according to the newly introduced Nicholson score and the Jellife formula and nomogram. The daily dose of digoxin was lower (p less than 0.01) according to the Nicholson score (mean 2.1 digoxin tablets of 62.5 micrograms daily). The mean serum concentration of digoxin was also lower (p less than 0.01) according to the Nicholson score (1.27 nmol/l) than according to the Jellife nomogram (1.84 nmol/l). Estimated by the Nicholson score the serum concentration of digoxin was not optimal (p less than 0.01) and not within an acceptable therapeutic range (p less than 0.01) in more patients than when estimated by the Jellife nomogram. It is concluded that the Nicholson score is not suitable for medical inpatients.

The day-to-day variation in serum digoxin concentration. The Hørsholm digoxin study.

Serum digoxin concentration was measured in 70 medical patients 7 and 8 days after admission to hospital. The digoxin treatment taken at home was continued in hospital. There was no statistically significant difference between mean digoxin concentrations in samples taken at day 7 (1.52 nmol/l) and day 8 (1.48 nmol/l). The variation in serum digoxin concentration from day to day expressed as SD was 0.25 nmol/l; 95% confidence limits were +/- 0.51 nmol/l, and 99% confidence limits +/- 0.67 nmol/l. Variations in serum digoxin concentration were not correlated to age, sex, body weight, serum creatinine and the oral dose of digoxin.

The injury experience observed in two emergency departments in Kingston, Ontario during 'ice storm 98'.

OBJECTIVES: 1) To describe patterns of unintentional injury presenting for emergency medical care in Kingston, Ontario following the ice storm in January 1998; and 2) to provide recommendations for prevention during such situations. METHODS: Unintentional injuries related to the ice storm that presented at the two emergency departments in Kingston, Ontario were identified and described. RESULTS: A total of 254 injuries were identified. Injuries peaked the day following the onset of the ice storm and again 4-6 days following the storm. Common sources of injury included slips and falls on the ice (56%), activities related to clearing brush or trees (15%), and unintentional carbon monoxide poisonings (9%). CONCLUSIONS: While the number of injuries that presented during the storm and its aftermath was not unusual, the distribution of injuries by type did reflect the irregular nature of environmental conditions. This analysis provides useful information for public officials to use reviewing disaster plans and to generate recommendations for managing future occurrences.
