目的:评估病房手工搬运患者护士发生职业性肌肉骨骼疾患（WMSDs）工作场所的MAPO指数，并了解工作场所中WMSDs发生的影响因素。方法:采用便利抽样法，于2019年3—5月选取某三甲医院26个病区的317名护士为研究对象。以一般资料调查表、MAPO评估方法、米尺为研究工具，采用现场调查和测量法，对病房手工搬运患者护士发生WMSDs工作场所的情况进行综合评估。依据MAPO指数将病区分为红灯、黄灯、绿灯3个风险等级，亮黄灯代表有必要执行中期和长期干预计划，亮红灯意味着必须执行短期干预计划。对病房手工搬运患者护士发生WMSDs的影响因素采用多因素Logistic回归分析。结果:本研究共发放问卷317份，回收有效问卷265份，有效回收率为83.6%。265名病房护士中，76.2%（202/265）的护士发生WMSDs。有13个（50.0%，13/26）病区亮红灯，包含158名（59.6%，158/265）护士；6个（23.1%，6/26）病区亮黄灯，包含92名（34.7%，92/265）护士；7个（26.9%，7/26）病区亮绿灯，包含15名（5.7%，15/265）护士。多因素Logistic回归分析显示，MAPO指数和病房分值是病房护士发生WMSDs的影响因素（n OR值分别为1.056、1.571；n P<0.05）。n 结论:病房护士工作场所发生WMSDs的风险较高，建议从病床类型、床间距、辅助设备、护理人力资源配置和职业防护培训方面入手来减少护士WMSDs的发生。“,”Objective:To evaluate the MAPO index of work-related musculoskeletal disorders (WMSDs) among ward nurses who manually handled patients, and to explore the influencing factors of WMSDs in the workplace.Methods:From March to May 2019, convenience sampling method was used to select 317 nurses from 26 wards of a ClassⅢ Grade A hospital. The General Information Questionnaire, MAPO index assessment, and the meter ruler were used to comprehensively evaluate the situation of WMSDs in the workplace of nurses who manually handled patients inwards with the method of on-site investigation and measurement. According to the score of the MAPO index, there were 3 risk levels of wards, namely red light, yellow light, and green light. The yellow light meant that it was necessary to implement the medium-term and long-term intervention plan, and the red light meant that the short-term intervention plan must be implemented. Multivariate Logistic regression was used to analyze the influencing factors of WMSDs in nurses who manually handled patients in the ward.Results:A total of 317 questionnaires were distributed and 265 valid questionnaires were returned with an effective response rate of 83.6%. In the 265 ward nurses, there were 76.2% (202/265) of nurses with WMSDs. There were 13 (50.0%, 13/26) wards with red lights, including 158 (59.6%, 158/265) nurses, and 6 (23.1%, 6/26) wards with yellow lights, including 92 (34.7%, 92/265) nurses, and 7 (26.9%, 7/26) wards with green lights, including 15 (5.7%, 15/265) nurses. Multivariate Logistic regression analysis showed that MAPO index and the ward score were the influencing factors for the occurrence of WMSDs among ward nurses with statistical differences (n OR=1.056, 1.571; n P<0.05) .n Conclusions:The risk of WMSDs in the workplace of ward nurses is high. It is recommended starting with the types of beds, bed spacing, auxiliary equipment, nursing human resource allocation, and occupational protection training to reduce the occurrence of WMSDs in nurses.
