Objective To investigate the preoperative design and application of the minimum foveolar translocation distance and angle of macular translocation. Methods The fundus fluorescein and indocyanine green an giographies were performed on 53 eyes of 53 patients with classic subfoveal choroidal neovascularization （SCNV）, including 42 with exudative age-related macular degeneration and 11 with high myopic macular degeneration. The actual area of macular SCNV and the minimum foveolar translocation distance and angle were analyzed. Results The actual area of SCNV was 0.39~18.00 mm2 with the mean of (3.08±3.22) mm2. The designed minimum superior translocation distance was 67~2 240μm with the mean of (845.72±425.23) μm；the minimum designed minimum inferior translocation distance was 53~2 430 μm with the mean of (912.17±547.77) μm. The minimum designed superior translocation angle was 1~32°with the mean of (13.23±6.6 8)°；the minimum designed inferior translocation angle was 1~35°with the mean of (14.06±8.46)°. The individual difference of the minimum designed superior and inferior translocation distance was more than 500 μm in 16 eyes （30.19 % ）, and the difference of translocation angle was more than 10°in 11（20.75%）. Conclusion Preoperative design of minimum translocation distance and angle of macular translocation may be helpful to choose the operation program. (Chin J Ocul Fundus Dis，2004，20：75-77)
Objective The ultimate goal of developing guidelines is for using them in clinical practice. In this study, an implementation evaluation tool was developed to promote the overall evaluation of guidelines and to improve their promotion and implementation. Methods The research group set up a team to formulate and establish a guideline implementation evaluation tool, through preliminary research, interviews, a systematic review of relevant literature, two expert consensus meetings and two Delphi expert consensus meetings to evaluate the guideline implementation tool. Experts were invited to give opinions and grades on the fields, items and overall implementation evaluation method of the tool. Results The evaluation tool for the implementation of guidelines included 5 fields, accessibility, communicability, performability, recognizability and applicability, with a total of 7 items. The scale-level CVIs in two rounds of Delphi expert consensus were 0.91 and 0.93. We collected opinions and suggestions and made some revisions and insertions without deleting any items based on the parameter that no items fulfilled the standard if mean <3.5, coefficient of variation >15% and I-CVI<0.78. Conclusion In this study, in order to provide a standard and method for the evaluation of guideline implementation, a guideline implementation evaluation tool has been developed and evaluated by clinically-related physicians and guideline formulation methodology experts. The guideline implementation evaluation tool presents satisfactory face and content validity. Empirical research is needed to verify the tool’s performance in evaluating guideline implementation.

Objective To evaluate the effect of teaching evidence-based medicine (EBM) in postgraduates. Methods One hundred and thirteen postgraduates in the second year grade selecting an EBM course were included. The course lasted four weeks (twice a week, 3 hours each time and total 21 hours). The courses were delivered in combination with cases. The teaching effect was evaluated by requesting the students to present an evidence-based case report on the five steps of evidence-based practice. Each teacher assessed the reports independently. Results The mean score of 107 EBM case reports was 51.35±11.38. Distribution of the mean score was nearly normal. Score distribution of the items: the full mark rate was 97% for case depiction and 62% for evidence searching. Stratified analysis: ① Formulating answerable clinical questions: the full mark rate was 88% for clear statement of patient type, 89% for clear statement of intervention, 35% for control and 36% for outcome statement, respectively. ② Searching evidence: the full marks rate was 95% for selecting relevant database, 90% for searching term, 68% for searching strategy and 79% for searching result depiction, respectively. ③ Critical appraisal of evidence: the full mark rate of critical appraisal of the clinical importance and validity of evidence was very low (35% and 7%respectively). ④ Evidence applying: the full mark rate of intervention’s benefit and risk for individual patient and patient’s value was higher than that of applying evidence to patients and intervention feasibility (24% and 21%, 16% and 12%). ⑤ Evaluation: the full mark rate of clinical result evaluation was higher than that of performance of evidence-based practice (55% and 17%). Conclusions Teaching EBM for postgraduates was successful, we need to strengthen the practice of critical appraisal and applying evidence for patients in the future EBM course.
ObjectiveTo analyze the roles of three scoring systems, i.e. Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ, Ranson’s criteria, and Sequential Organ Failure Assessment (SOFA), in predicting mortality in patients with severe acute pancreatitis (SAP) admitted to intensive care unit (ICU), and explore the independent risk factors for mortality in SAP patients.MethodsThe electronic medical records of SAP patients who admitted to ICU of West China Hospital, Sichuan University between July 2014 and July 2019 were retrospectively analyzed. Data of the first APACHE Ⅱ, Ranson’s criteria, SOFA score, duration of mechanical ventilation, the use of vasoactive drugs and renal replacement therapy, and outcomes were obtained. The receiver operator characteristic (ROC) curve was used to evaluate the value of APACHE Ⅱ score, Ranson’s criteria, and SOFA score in predicting the prognosis of SAP. Logistic regression models were created to analyze the independent effects of factors on mortality.ResultsA total of 290 SAP patients hospitalized in ICU were screened retrospectively, from whom 60 patients were excluded, and 230 patients including 162 males and 68 females aged (51.1±13.7) years were finally included. The ICU mortality of the 230 patients with SAP was 27.8% (64/230), with 166 patients in the survival group and 64 patients in the death group. The areas under ROC curves of APACHE Ⅱ, Ranson’s criteria, APACHE Ⅱ combined with Ranson’s criteria, and SOFA score in predicting mortality in SAP patients admitted to ICU were 0.769, 0.741, 0.802, and 0.625, respectively. The result showed that APACHE Ⅱcombined with Ranson’s criteria was superior to any single scoring system in predicting ICU death of SAP patients. The result of logistic regression analysis showed that APACHE Ⅱ score [odds ratio (OR)=1.841, 95% confidence interval (CI) (1.022, 2.651), P=0.002], Ranson’s criteria [OR=1.542, 95%CI (1.152, 2.053), P=0.004], glycemic lability index [OR=1.321, 95%CI (1.021, 1.862), P=0.008], the use of vasoactive drugs [OR=15.572, 95%CI (6.073, 39.899), P<0.001], and renal replacement therapy [OR=4.463, 95%CI (1.901, 10.512), P=0.001] contributed independently to the risk of mortality.ConclusionsAPACHE Ⅱ combined with Ranson’s criteria is better than SOFA score in the prediction of mortality in SAP patients admitted to ICU. APACHE Ⅱ score, Ranson’s criteria, glycemic lability index, the use of vasoactive drugs and renal replacement therapy contribute independently to the risk of ICU mortality in patients with SAP.

ObjectivesTo evaluate the quality of evidence-based guidelines for the treatment of female stress urinary incontinence, so as to provide evidence for clinical stress urinary incontinence management research.MethodsWebsite of the professional society, clinical practice guide website, Yimaitong website, PubMed, CNKI, WanFang Data and VIP databases were electronically searched to collect stress urinary incontinence management related guidelines from January 1st, 2014 to January 1st, 2019. Two reviewers independently screened literature, extracted data and evaluated the quality of included guidelines using Appraisal of Guidelines for Research and Evaluation (AGREE Ⅱ) and the characteristics of each guidelines were analyzed.ResultsWe identified totally 8 relevant evidence-based guidelines in this field. The average standardized scores in the 6 domains of AGREE II were 90.74% (scope and purpose), 78.71% (stakeholder involvement), 74.60% (rigor of development), 93.52% (clarity of presentations), 61.81% (applicability), and 91.67% (independence). The overall standardized scores of 8 guidelines were 77.70%, and the total scores were 5.31 (out of 7). For overall quality, 4 of them were grade A and 4 of them were grade B.ConclusionsThe overall quality of evidence-based guidelines for stress urinary incontinence is high, and scores in different fields are vary large. Fields of " stakeholder involvement”, " rigor of development” and " applicability” with lower scores still requires strengthening. The current guidelines for female stress urinary incontinence in China still fails to meet the standards of evidence-based guidelines, so the quality of the guidelines should be improved to improve guide clinical practice.
