Background: With the rise of social media and other web-based platforms, there has been a shift in how medical research findings are disseminated. Questions/Purposes : We sought to investigate how often orthopedic surgeons use different knowledge-seeking methods and how confident they were in their ability to stay up-to-date. Methods : We distributed a 23-question survey to 120 orthopedic surgeons employed at a single tertiary-care metropolitan orthopedic hospital. The survey collected the surgeons' use of reference managers, RSS feeds, and preferred methods of staying up-to-date. Respondents were asked to report the number of hours they spent staying up-to-date per week and their success with keeping up with orthopedic specialty literature. Results : A total of 85 physicians responded (median age, 52 years); 83% of respondents who spent 3 or more hours a week in keeping up-to-date with the literature said they felt successful in doing so, while 40% of participants who spent less than 1 hour a week said they felt successful. Fifty-five percent of surgeons under the median age used social media, while only 29% of surgeons over the median age used social media. Conclusions : This survey suggests that spending only 1 to 2 hours per week was enough to make the orthopedic surgeons we surveyed feel confident that they were keeping up with the literature in their specialty. These findings also suggest that it may be more important for surgeons to choose a convenient method of literature review that will enable them to maximize time spent reading, rather than attempting to use any one source., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Peter D.

Epidemiological studies are essential in medicine and public health as they help identify risk factors and causes of diseases. Additionally, they are key to planning, implementing, and evaluating health interventions aimed at preventing and controlling the spread of diseases. Among these studies, analytical observational studies, such as cross-sectional, case–control, and cohort studies, are the most used. The validity of their results largely depends on the robustness of the design, execution, and statistical analysis. Objective: The objective of this study is to examine the most common errors in the selection of methodological design and statistical tests in analytical observational studies and to provide recommendations to correct them. Methodology: A comprehensive review of the available literature on methodology in epidemiological observational studies was conducted, focusing on cross-sectional, case–control, and cohort studies. Common errors in the selection of designs and statistical tests were identified and analyzed. Results and Conclusions: Errors in the selection of methodological design and statistical tests are common in epidemiological observational studies. Based on the identified errors, a series of recommendations is provided to improve the selection of methodological design and statistical tests, thereby increasing the reliability of the results in cross-sectional, case–control, and cohort studies.
