Table H.1.9. Study #9: Yassi, A. Utilizing data systems to develop and monitor occupational health programs in a large Canadian hospital, Methods of Information in Medicine. 1998; 37(2): 125-129.
To describe the methods used to implement this data system and some of the results attributable to utilizing databases, to guide occupational health programs in this hospital during the last 6 years.
Experimental Design: TIMES SERIES
Time series involving WCB Assessments for hospital and the overall health care industry in Manitoba. Time series covered yearly intervals 1990-1995.
The sample consists of one worksite, an acute and tertiary care teaching hospital in inner-city, Winnipeg. There are 6000 employees.
Maintenance of Sample:
Changes in workforce not mentioned (except increase in payroll $25 million (17%) from 1990-95); payroll in terms of dollars gradually increased over the period 1990-92 and then leveled from 1992-95. Thus, there seemed to be no major changes.
Intervention: VOLUNTARY OHSMS
The hospital's Department of Occupational and Environmental Medicine adopted a new risk assessment/risk management approach to occupational hazards (biological/chemical; physical; ergonomic; psychosocial). It consisted of: improved record-keeping (i.e., coding injuries); more systematic data collection and analysis, assisted by databases; hazard identification; risk assessment; planning programs to address risks; defining the programs’ objectives and standards; assigning the responsibility for particular programs to particular individuals; program evaluation or surveillance; performance measurement; and continuous improvement; economic evaluation.
Data Collection, Data Transformation, and Measurement Properties:
Outcomes 6 Economic Outcomes
One measure is the hospital’s Worker’s Compensation Board premium rate ($ per 100$ payroll). A second measure is the accumulated savings in worker’s compensation payments from 1991-95. This was calculated by first applying the hospital’s 1990 premium rate ($1.51 per $100 payroll) to each of the payroll values for the five years subsequent, in order to estimate what the premium payments would have been in the absence of the program. The amounts actually paid for each of those years were then subtracted from the respective estimated amounts, and the differences were the estimated annual savings.
