Objective:To use the best evidence of noninvasive mechanical ventilation related pressure injury prevention in the clinic guided by integrated promoting action on research implementation in health services framework (i-PARIHS) and evaluate its effect.Methods:This study is an unsynchronized before and after control study. Convenience sampling method was used to select patients receiving non-invasive mechanical ventilation from 7 wards of Beijing Hospital from October 2019 to September 2021. A total of 575 patients receiving non-invasive mechanical ventilation from October 2019 to September 2020 were included in the control group and 602 patients from October 2020 to September 2021 were included in the trial group. The control group adopted the usual care measures, and the trial group applied the prevention program for noninvasive ventilation related facial pressure injuries. The incidence of pressure injury was compared between the two groups. Nurses in 7 wards were investigated before and after the intervention program to compare the changes of knowledge level.Results:In the control group, there were 354 males, 221 females, aged (77.13 ± 14.49) years old; in the trial group there were 392 males, 210 females, aged (75.60 ± 14.27) years old. The incidence of pressure injury in the trial group was lower than the control group, but showed no significant difference ( P>0.05). In the control group, 11 cases suffered pressure injury, including 5 cases in stage 2, 6 cases in stage 3 and above. There were 9 cases in the trial group, including 8 in stage 2 and 1 in stage 3 and above. The severity of pressure injury in the trial group was lower than that in the control group, and the difference was significant ( χ2 = 3.83, 4.11, both P<0.05). The scores of the nurse′pressure injury knowledge increased from (6.77 ± 1.53) points to (7.15 ± 1.47) points, with a significant difference ( t = -2.31, P<0.05). Conclusions:Management of the prevention of noninvasive mechanical ventilation related facial pressure injury through evidence-based practice can reduce its incidence, reduce its severity, and it is beneficial to improve the clinical nurses' prevention knowledge and clinical practice level of facial pressure injury related to non-invasive mechanical ventilation.

Objective:To understand the status quo of the job preparedness among newly recruited nurses and analyze its influencing factors.Methods:Totally 355 newly recruited nurses who joined 5 Class Ⅲ Grade A hospitals nationwide between September 2021 and September 2022 were selected by convenience sampling and investigated by general information surveys, the Work Readiness Scale for Graduate Nurses and the Transition Shock of Newly Graduated Nurses Scale. Logistic regression was employed to analyze the influencing factors of the job preparedness among these newly recruited nurses.Results:A total of 355 questionnaires were distributed, and 350 valid responses were received, with a valid response rate of 98.6%. The overall score for the job preparedness of the newly recruited nurses was (271.05±49.97), with a standardized total score of (73.26±13.57). 208 individuals (59.4%) scored high (standardized total score ≥70), while 142 individuals (40.6%) scored low (standardized total score<70). Logistic regression analysis revealed that the department of employment, part-time job experience, harmonious relationships with classmates during schooling, and the level of transition shock were influencing factors for the job preparedness of the newly recruited nurses ( P<0.05) . Conclusions:The job preparedness of newly recruited nurses is influenced by various factors. Nursing educators and managers should adopt targeted educational and management strategies based on the nurses' different experiences, interpersonal relationships, department of employment, and level of transition shock to enhance their job preparedness.
