In particular, issues regarding the documentation process, control and calibration of 4,000 pieces of medical equipment and the impact on staffing levels for in-house trained personnel to undertake the audits are described. The impact on the service to date, including benefits and drawbacks, is covered, along with aspirations for the future. Kuopio Hospitals adopted some techniques during the implementation process which did not work as successfully as others.
