Prevalence and associated factors of corneal blindness in Ningxia in northwest China

AIM:To describe the prevalence and demographic characteristics of corneal blindness in an urban and rural region of Ningxia,located in the northwest part of China.METHODS:A stratified,randomized sampling procedure was employed in the study,including urban and rural area of all age group.Visual acuity,anterior segment and ocular fundus were checked.Related factor of corneal disease,including age,gender,education status,ethnic group,location and occupation,were identified according to uniform customized protocol.An eye was defined to be corneal blindness if the visual acuity was【20/400 due to a corneal disease.RESULTS:Three thousand individuals(1290 from urban area and 1710 from rural area)participated in the investigation,with a response rate of 80.380%.The prevalence of corneal blindness was 0.023%in both eyes and 0.733%in at least one eye.The blindness in at least one eye with varied causes was present in 106participants(3.533%)and in bilateral eyes in 34participants(1.133%).The corneal diseases accounted for 20.754%of blindness in at least one eye and 20.588%of bilateral blindness.The prevalence of corneal disease was higher in older and Han ethnic group,especially those who occupied in agriculture and outdoor work.People with corneal blindness were more likely to be older and lower education.Rural population were more likely to suffer from bilateral corneal blindness than the urban population in≥59-year group(χ2=6.716,P=0.019).Infectious,trauma and immune corneal disease were the three leading causes of corneal disease.Trauma cornealdisease was more likely leading to blindness in one eye.However,infectious and immune corneal diseases make more contribution to the bilateral corneal blindness.CONCLUSION:Corneal blindness is a significant burden of in Ningxia population,encompassing a variety of corneal infections and trauma;the majority of those were avoidable.Health promotion strategies and good hygienic conditions have to be developed.

Evaluation and analysis of the effect of continuing education on nurses’physical restraint knowledge,attitude,and behavior

Objective:The objective of the study is to construct a training course for physical restraint(PR)evidence‑based practice project and apply it to verify its effect.Methods:A total of 162 nurses from five departments of a general hospital in Beijing were trained to compare the PR knowledge,attitudes,and behaviors of nurses before and after training.Results:The nurses were satisfied with the overall curriculum;the total scores of PR’knowledge,attitude and behavior of nurses after training were higher than before,and the difference was statistically significant(P<0.05);the total scores of nurses who received evidence‑related training before this training were higher than those of nurses who did not receive relevant training,and the difference was statistically significant(P<0.05).Conclusion:Continuing education can effectively improve nurses’knowledge,attitude,and behavior level of PR,ensure patient safety,and promote physical and psychological rehabilitation of patients.
