Objective To compare the screening ability of the Timed Up and Go Test (TUG),Berg Balance Scale (BBS),Single Leg Stance (SLS) and Brief-Balance Evaluation Systems Test (Brief-BESTest) for fall risk in people with chronic obstructive pulmonary disease (COPD),and to provide references for clinical selection of appropriate screening tools for balance function. Methods From February 2020 to February 2021,a total of 86 COPD patients hospitalized in the department of respiratory and critical care medicine of a tertiary hospital in Guangdong were selected by convenience sampling method. Their balance abilities were assessed using the TUG,BBS,SLS and Brief-BESTest. Taking 3-month history of falls as the diagnostic standard,the identification ability of the 4 scales for falls was compared by Bayes discriminant analysis and the area under the receiver operating characteristic curve (AUC). Results The cross-validation accuracy of TUG,BBS,SLS and Brief-BESTest were 60.47%,68.60%,51.16% and 72.09%. The Brief-BESTest showed the biggest area under ROC curve (0.818),compared with BBS (0.758),TUG (0.686) and SLS (0.568). At the cutoff score of 14,the Brief-BESTest demonstrated a positive test accuracy of 0.786 with the sensitivity of 0.739,the specificity of 0.825. Conclusion Among the 4 balance function tests,brief-BESTest was the best at screening a history of falls in COPD patients. Brief-BESTest was recommended for clinical staff to assess balance and predict fall risk in patients with COPD.

Objective To understand the current situation of perioperative hypothermia management in 85 hospital operating rooms in Guangdong Provinces,so as to find out the deficiencies and provide references for the nursing practice in operating rooms. Methods A convenient sampling method was used to conduct a questionnaire survey on all the members of the Operating Room Professional Committee of Guangdong Nursing Association in February 2019. A self-developed questionnaire was used,including general information and the current management of perioperative hypothermia. Results A total of 85 valid questionnaires were received,with an effective recovery rate of 98.84%. 23（27.06%） hospitals have implemented pre-warming;Only 6 hospitals（7.06%） carried out perioperative hypothermia risk assessment. 21（48.84%） tertiary hospitals and 9（25.71%） secondary hospitals have established hypothermia emergency plans,with statistical differences（ χ ²=4.359,P=0.037）;in 25（58.14%） tertiary hospitals and 1（2.86%） secondary hospitals,the core temperature was measured by the same method before operation,and the difference was statistically significant（ χ ²=24.106,P<0.001）. 34（40.00%） hospitals required temperature handover after operation. 20 hospitals（23.53%） paid attention to the temperature regulation of patient transferring environment after operation. Conclusion Perioperative temperature management in 85 hospitals in Guangdong Province was incomplete. The implementation rates of pre-warming,risk assessment of hypothermia and establishment of emergency procedures,the same temperature measurement method of preoperative and intraoperative temperature,postoperative handover temperature,adjustment of the post-transport environment temperature are not high. Perioperative hypothermia prevention knowledge training and practice need to be strengthened and promoted.
