Appendix H - Detailed Summary of Evidence
Table H.1.1. Study #1: Alsop, P. and LeCouteur, M. Measurable success from implementing an integrated OHS management system at Manningham City Council, Journal of Occupational Health & Safety - Australia & New Zealand. 1999; 15(6): 565-572.
What were the achievements and key learning experiences that were obtained through the implementation of a health and safety management program integrated into other management systems at Manningham City Council?
Experimental Design: TIME SERIES
Time series design, with yearly measures of financial benefits (premium rates) from 1992/93 to 1999/2000
Sample consisted of one municipal government (Manningham City Council, a metropolitan local government near Melbourne, Australia) employing >500 people. The municipality was located 15 km east of Melbourne, Australia.
Maintenance of Sample:
Some employment changes over the period of observation are reported, with a 25% reduction in the size of the workforce. An amalgamation and restructuring of business units took place that the authors suggested caused slower than expected progress.
Intervention: VOLUNTARY OHSMS
In May 1995, work began on the implementation of an OHSMS based on "various Australian and international standards" (not further described in article). It involved the integration of OHS management with Quality Management (ISO 9001), and Environmental Management (ISO 14001) Systems. Emphasis was on common corporate processes (e.g. training, procurement and supply, hazard identification and incident reporting, risk assessment and control) and those factors/risk exposures which were business-unit specific (e.g., tree cutting, lifting of frail aged). SafetyMAP Achievement levels sought and achieved (Initial Level Achievement since Aug ’98 for all operations and Advanced Level Achievement since June ’99 for largest business unit.) Intervention initiated by municipal government.
Data Collection, Data Transformation, and Measurement Properties:
Outcomes 6 Economic Outcomes
Workers Compensation Premiums 1991/92 to 1999/2000. Results also given for net premium rates for individual business units, in comparison to industry rate. We don’t, however, have the equivalent comparison from before OHSMS instituted.
