Objective To investigate the clinical treatment of nonpenetrated cornea trauma caused by crops. Methods Clinical data of 128 cases of nonpenetrated cornea trauma caused by crops were retrospectively analyzed. According to the interval time between occurrence of trauma and clinic visiting, the patients were divided into 3 groups:group A (33 cases,<24 h), group B (72 cases, 24 h≤interval time<1 week) and group C (23 cases, ≥ 1 week). The therapeutic effects and prognosis were analyzed. Results There was statistical difference in the incidence of corneal ulcer among group A, group B and group C: 6.1% (2/33), 62.5% (45/72) and 100.0% (23/23), χ2= 52.32, P<0.01. In group B, 12 cases were treated with conjunctival flap covering, 2 cases received keratoplasty and 2 cases undertook enucleation. In group C, 10 cases were treated with conjunctival flap covering, 4 cases received keratoplasty and 2 patients undertook enucleation finally. All the other patients were cured with local debridement and medical treatment. Conclusions Patients with nonpenetrated cornea trauma caused by crops may develop infectious keratitis, and prompt and proper treatment can avoid the secondary infection and improve the outcome. Local debridement in combination with iodophors disinfection can prevent the incidence of infectious keratitis. Conjunctival flap covering is an effective technique in the treatment of corneal ulcer caused by nonpenetrated cornea trauma.

Objective To analyse the effect on implementation of the International Guidelines for Clinical Treatment of Pressure Injuries within leadership-staff-performance improvement-information technology(LSPI)framework of quality improvement,therefore to provide theoretical insights in promoting the transformation of prevention and treatment practice guidelines to clinical practices.Methods A pre-and post-control study was in this study.A total of 101 005 inpatients admitted to our hospital between July 2019 and June 2020 were assigned to a control group,and the other 110 824 patients who were hospitalised between July 2020 and June 2021 were assigned to a trial group.The two groups were compared in terms of the promptness rate and accuracy of primary risk assessment,response rate of high-risk patients and incidence of pressure injury before and after implementation of the guideline.Results After implementation of the guideline,the promptness rate and the accuracy of primary risk assessment and the rate of preventive measures in high-risk patients increased from 86.73%to 96.25%,93.46%to 98.69%and 94.21%to 98.15%,respectively.The incidence of hospital pressure injury decreased from 0.77‰ to 0.29 ‰.All the differences were statistically significant(all P＜0.05).Conclusions Implementation of the International Guidelines for the Clinical Treatment of Pressure Injuries within the LSPI framework of quality improvement can improve the quality of process management in pressure injury and reduce the incidence of pressure injuries.Therefore,it can facilitate the guideline-based code of practice in the clinical practices.
