This paper examines whether improving physical ergonomics working conditions affects worker productivity in a call centre with computer-intensive work. A field study was conducted at a catalogue retail service organization to explore the impact of ergonomics improvements on worker production. There were three levels of ergonomics interventions, each adding incrementally to the previous one. The first level was ergonomics training for all computer users accompanied by workstation ergonomics analysis leading to specific customized adjustments to better fit each worker (Group C). The second level added specific workstation accessories to improve the worker fit if the ergonomics analysis indicated a need for them (Group B). The third level met Group B requirements plus an improved chair (Group A). Productivity data was gathered from 72 volunteer participants who received ergonomics improvements to their workstations and 370 control subjects working in the same departments. Daily company records of production outputs for each worker were taken before ergonomics intervention (baseline) and 12 months after ergonomics intervention. Productivity improvement from baseline to 12 months post-intervention was examined across all ergonomics conditions combined, and also compared to the control group. The findings showed that worker performance increased for 50% of the ergonomics improvement participants and decreased for 50%. Overall, there was a 4.87% output increase for the ergonomics improvement group as compared to a 3.46% output decrease for the control group. The level of productivity increase varied by the type of the ergonomics improvements with Group C showing the best improvement (9.43%). Even though the average production improved, caution must be used in interpreting the findings since the ergonomics interventions were not successful for one-half of the participants.
BACKGROUND: Information technology, or IT, applications for dental practice continue to develop rapidly. More than 85 percent of all dentists use computers in their offices, and the number of clinical uses for the computer is on the rise. This article discusses the state of the art of several technologies, provides an integrative view of a technologically well-equipped office and offers several guidelines for technology purchasing decisions. CONCLUSIONS: Most administrative applications are relatively mature and are required for the smooth functioning of today's dental offices. Clinical applications--such as dental and medical health histories, charting, digital imaging, diagnostic and treatment applications, and decision support--vary in their degree of maturity. Most Internet applications-such as Internet-based scheduling and e-mail communication with patients--still are an optional adjunct for dental practices. PRACTICE IMPLICATIONS: Practitioners should develop a comprehensive plan for implementing or updating the IT infrastructure in their offices. Issues to be considered in technology purchasing decisions include usability, integration, work flow support, cost-benefit analysis and compliance with standards.
