The high incidence of musculoskeletal disorders (MSDs) among healthcare workers suggests that the introduction of ergonomic interventions could be beneficial. While laboratory studies have clearly documented the efficacy of ergonomic devices, few studies have examined their effectiveness in the healthcare workplace.
This study evaluated a statewide program that provided ergonomic consultation and financial support for purchasing ergonomic devices, which aid in patient handling and lifting. Changes in MSD rates between baseline (1 year pre-intervention) and post-intervention (up to 2 years) periods were examined in 100 work units in 86 healthcare facilities.
The median MSD rate decreased from 12.32 to 6.64 per 200,000 employee-hours, a decrease greater than the secular trend for the study period (1999-2003).
This study suggests that ergonomic consultation and financial support for purchasing ergonomic equipment can be an effective intervention to reduce MSDs among healthcare workers.
医护人员中肌肉骨骼疾病（MSD）的高发病率表明，引入人体工程学干预措施可能有益。虽然实验室研究已明确证明人体工程学设备的功效，但很少有研究考察其在医疗工作场所的有效性。
本研究评估了一项全州范围的项目，该项目提供人体工程学咨询并为购买有助于患者搬运和抬举的人体工程学设备提供资金支持。在86家医疗机构的100个工作单位中，考察了干预前1年（基线期）和干预后（长达2年）期间MSD发生率的变化。
MSD发生率中位数从每200,000员工工时12.32降至6.64，降幅大于研究期间（1999 - 2003年）的长期趋势。
本研究表明，人体工程学咨询以及为购买人体工程学设备提供资金支持，可能是减少医护人员MSD的有效干预措施。
