Background In March 2020 lockdown due to the COVID-19 pandemic forced Polish Medical Universities to implement e-learning. The aim of the study was to evaluate the perception of e-learning by students of Medical Universities in Poland. Material and methods Survey was performed nationwide via the Internet from 30th November 2020 to 10th February 2021. Six hundred fifteen (615) medical students completed the survey. The study questionnaire included questions concerning sociodemographic data, perception of lecturers’ effectiveness, assessment of stationary and online classes, changes in learning habits and restrictions on education, and advantages and disadvantages of e-learning. Results The respondents reported that 96.1% of lectures, 85.5% of seminars, and 40.0% of clinical classes were implemented by e-learning. The lectures conducted by e-learning were assessed as good and very good by 78.4% and seminars by 51.2% of respondents. While the clinical classes conducted by e-learning were assessed as bad and very bad by 62.9% of respondents. The most frequently indicated limitations of e-learning were the quality of the content and available materials (26.9%), restrictions in direct contact with the lecturer (19.6%), Internet connection (16.8%), and home conditions (13.8%). Only 4% of the students had to buy or retrofit computer equipment. Any other limitations were indicated by 9.7% of the respondents. Conclusions Students were highly accepting of lectures and seminars conducted in the form of e-learning, but not laboratory and clinical classes. The main problems in e-learning are the quality of the classes conducted and the Internet connection. The students expect e-learning classes to be conducted in real-time, with direct, face-to-face contact with the lecturer.

Total hip arthroplasty (THA) is one of the most frequent orthopedic procedures worldwide and its surgical volume is constantly growing. To address the patients' restricted access to healthcare resources and limited one-on-one contact with the surgeon during the COVID-19 pandemic, we created a reliable source of information for patients undergoing THA. The use of mHealth is increasing with access to modern technology in Poland. Information related to health issues is the second most common web search performed by older adults. Our project aimed to create the first Polish mobile application for THA patients: Endopedia. Endopedia was developed for the Android platform based on a survey performed among patients and a collection of frequently asked questions on patients' internet forums. The content was adapted to the elderly and visually impaired requirements. mHealth solutions should not replace one-on-one conversation, but they can provide substantial support for patients in conditions of limited information.
