Objective:To construct a risk assessment model based on probabilistic hesitant fuzzy set(PHFS)for pressure-related injuries in medical equipment,and analyze its application value in control and management for risk of pressure-related injuries in medical equipment in the department of emergency.Methods:The frequency of events caused by pressure-related injuries of equipment was counted as statistical method.Combined with the risk assessment factors of pressure-related injuries,the technique for order preference by similarity to ideal solution(TOPSIS)based on PHFS was used to evaluate the risk level of pressure-related injuries of equipment,and formulate corresponding measures for risk management of pressure-related injuries.A total of 120 used medical equipment at the Department of Emergency of the First Affiliated Hospital of Xi'an Jiaotong University from January 2024 to December 2024 were selected.Using the random number table method,60 equipment were managed with the conventional risk management mode for pressure-related injuries(conventional management mode),and the other 60 equipment were managed with risk assessment model based on PHFS(model management mode)for pressure-related injuries in medical equipment.The incidence of pressure-related injuries of equipment,scores of operational quality of equipment,incidence of pressure-related injuries at different staging were compared between two kinds of management modes.A self-made questionnaire was used to investigate the satisfactions of emergency doctors,nurses,patients,and medical engineers in the department of equipment,who used and managed equipment.Results:The scores of operational standardization,pressure controllability,and diagnostic comfort in the model management mode were respectively(93.36±4.56),(90.54±3.69)and(93.65±4.69)points,which were significantly higher than those in the conventional management mode,while the score of material sensitivity was(30.23±3.26)points,which was significantly lower than that in the conventional management mode(t=15.941,11.896,11.511,17.200,P<0.05).The incidences of occurring pressure-related injuries in the referred logs of diagnosis and treatment of respiratory equipment,monitoring equipment,infusion equipment,and oxygen supply equipment in the model management mode were significantly lower than those in the conventional management mode(x2=9.924,9.493,9.796,8.075,P<0.05).The incidences of stage 1,2,3,and 4 of pressure-related injuries of equipment in the model management mode were significantly lower than those in the conventional management mode(x2=7.209,6.985,8.048,7.473,P<0.05).The satisfactions of emergency doctors,nurses,patients,and medical engineers in the department of equipment for the clinical use of equipment in the model management mode were significantly higher than those in the conventional management mode(t=12.499,13.200,14.410,9.226,P<0.05).Conclusion:The risk assessment model based on PHFS for pressure-related injury of medical equipment can reduce the incidences of pressure-related injuries of medical equipment in the department of emergency,and improve the safety of using medical equipment,and enhance the service quality of clinical equipment,and increase the satisfaction for equipment in clinical applications.

Objective:To investigate the effect of preoperative continuous fascia iliaca compartment block (FICB) on perioperative opioids dosage and quality of postoperative recovery in elderly patients with frail.Methods:A prospective study method was used. Sixty elderly frail patients underwent selective unilateral femoral head replacement surgery from November 2022 to October 2024 in Sihui People′s Hospital were selected. The patients were divided into control group and FICB group by random digits table method with 30 cases each. The patients in control group did not receive continuous FICB before surgery, and the patients in FICB group received continuous FICB 1 d before surgery. The perioperative use of opioids and analgesic effect, operative time, intraoperative blood loss, postoperative hospital stay, quality of recovery-40 (QoR-40) score at discharge and postoperative complications were compared between the two groups.Results:A total of 57 patients completed the study, with 29 cases in the FICB group and 28 cases in the control group. There were no statistical differences in operative time, intraoperative blood loss and postoperative hospital stay between the two groups ( P>0.05). The sufentanil dosage of patient-controlled analgesia (PCA), perioperative nalbuphine dosage, frequency of perioperative visual analog score (VAS)>4 scores, rate of preoperative rescue analgesia, rate of postoperative rescue analgesia and pressing frequency of PCA in FICB group were significantly lower than those in control group: (94.1 ± 5.4) μg vs. (102.1 ± 6.1) μg, 0 (0, 0) mg vs. 10.0 (0, 20.0) mg, 3.0 (2.0, 5.0) times vs. 5.0 (4.0, 6.0) times, 3.4% (1/29) vs. 32.1% (9/28), 13.8% (4/29) vs. 39.3% (11/28) and 2.0 (1.0, 3.0) times vs. 4.0 (3.0, 5.0) times, and there were statistical differences ( P<0.01 or <0.05). The total QoR-40 score and physical comfort, pain scores in FICB group were significantly higher than those in control group: 156(153, 161) scores vs. 153 (148, 159) scores, 47 (45, 50) scores vs. 45 (43, 47) scores and 30 (29, 31) scores vs. 28 (25, 30) scores, and there were statistical differences ( P<0.05 or <0.01); there were no statistical differences in emotional state, physical independence and psychological support scores between the two groups ( P>0.05). The incidences of dizziness and nausea vomiting in FICB group were significantly lower than those in control group: 13.8% (4/29) vs. 42.9% (12/28) and 10.3% (3/29) vs. 35.7% (10/28), and there were statistical differences ( P<0.05); there were no statistical difference in the incidences of delirium, pulmonary infection and deep vein thrombosis in the lower extremities between the two groups ( P>0.05). Conclusions:Preoperative continuous FICB can reduce perioperative opioids dosage in elderly patients with frail, and improve early stage postoperative recovery quality.

Objective:To analyze the dosage distribution and the frequency of each dosage of high-risk tablets in the hospitalized patients in a children's hospital,and study whether the existing specifications of high-risk tablets meet the pediatrics clinical needs. Methods:All the prescriptions including high risk tablets were analyzed from 2014 to 2016 in Shanghai children's medical center. The frequency of every dosage of every drug was analyzed,and the current specifications were judged according to the frequency. New specifications were proposed when the existing specifications did not match the clinical needs. The new frequency of the proposed speci-fications was re-accounted for all the three-year prescriptions in order to evaluate whether the proposed new specifications met the clini-cal needs. Results:Among the five kinds of high-risk oral tablets,methotrexate tablets and vitamin A acid tablets were in accordance with the actual clinical requirements. Mercaptopurine tablets should add two specifications including 12.5 mg and 17 mg,and warfarin sodium tablets should add one specification(1.25 mg). Hydroxyurea tablets(250 mg) and warfarin sodium tablets(1 mg) were rec-ommended used in the children's hospital. Conclusion:The existing specifications of high-risk oral tablets can't fully meet the clini-cal needs,therefore,specifications still needs to be adjusted.
