Assessing the completeness of reporting of observational studies in Colombian Journal of Anesthesiology. Cross sectional study

Introduction The STROBE statement (Strengthening the Reporting of Observational Studies in Epidemiology), consisting of 22 points, was published in 2007 with the aim of improving the reporting of observational research. Objective To determine the completeness of reporting of observational studies published in the Colombian Journal of Anaesthesiology between 2000 and 2013 using STROBE. Methods Cross-sectional study. The units of analysis were observational studies published in Colombian Journal of Anaesthesiology between 2000 (volume 28) and 2013 (volume 41). Of the randomly selected studies, 40% were included. The primary outcome was the completeness of the report of each study. Using two groups, the researchers applied the STROBE statement independently, supported by an arbitrator. Descriptive analyses, time series analyses and multiple linear regression analyses were used. Results Overall, 55 studies were identified and 22 (40%) were randomly chosen. The median overall completeness according to STROBE was 57% (95% CI: 48%-66%). Items with higher completeness in the reports were the Title and Introduction (89% each), followed by Methods (53%), Results (50%), and Discussion (58%). There were no significant differences between before and after the publication of STROBE. Conclusion The completeness of reporting of observational studies in the Colombian Journal of Anaesthesiology is close to 60%, according to results worldwide. No change was found as a result of the publication of the STROBE Statement in 2007
