RESUMEN
Objective To evaluate the effects of simulation training based on the concept of experiential education on im-proving first aid skills of medical staff in nursing homes.Methods The assessment data of 120 medical staff participating in first aid simulation training in our nursing home from January 2020 to June 2023 were retrospectively analyzed.Using a self-controlled design,the changes in skills operation,reaction time,team cooperation,etc.were statistically analyzed.Results All indicators were significantly improved after training.The skill operation score increased by 12.4 points(P＜0.05),the average reaction time decreased by 5.2 seconds(P＜0.05),and the team cooperation score increased by 13.8 points(P＜0.05)compared with before training.Conclusion Simulation training based on the experiential education model can effectively improve the first aid skills and cooperation ability of medical staff,which is an important means to continuously improve the emergency response capac-ity in nursing homes.
RESUMEN
Objective To establish normal reference ranges for serum cystatin C (Cys C)in relatively healthy middle-aged and elderly(＞50 years)Chinese individuals.Methods A total of 1087 candidates were consecutively selected and serum Cys-C levels were measured by transmission turbidimetry.Frequency analysis and histogram were used to establish the 95％ confidence reference range according to methods provided by CLSI (C28-A2).Results Based on the definition and verification procedures for clinical laboratory reference ranges(CLSI C28-A2,second edition),Cys-C levels of 1087 participants fell within the range of 0.30-1.55 mg/L;Male participants had higher serum Cys-C levels than female participants(Z=-10.19,P＜0.01).The serum Cys-C level increased with age,regardless of gender(R =0.600,P＜ 0.01).Differences in Cys-C levels between age groups were statistically significant (x2=411.17,P＜ 0.01).The reference ranges of normal serum Cys-C levels for different age groups (50-,55-,60-,65-,70-,75-,) were 0.42-0.98mg/L,0.45-1.04mg/L,0.47-1.34mg/L,0.46-1.38mg/L,0.61-1.33mg/L,0.61-1.28 mg/L,respectively,for males,and 0.39-0.94mg/L,0.42-1.01mg/L,0.40-0.91mg/L,0.46-1.03mg/L,0.57-1.04mg/L,0.55-1.27mg/L,respectively,for females.Conclusions This study established preliminary normal serum Cys-C reference ranges for healthy middle-aged and elderly(＞ 50 years)individuals in this region,which can serve as parameters for disease diagnosis and treatment evaluation.
