We developed a WeChat applet\u2013based National Remote Emergency System for Malignant Hyperthermia (MH-NRES) to provide a real-time emergency system to help Chinese anesthesiologists deal with MH crises. However, it is imperative that close attention should be paid to the usability of the applet.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Purpose<\/jats:title>\n                <jats:p>The objectives of this study were to (1) evaluate the usability of the applet-based MH-NRES for anesthesiologists; and (2) to test the validity and reliability of a modified mHealth app usability questionnaire.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A modified User Version of the Mobile Application Rating Scale (uMARS) was designed. Together with System Usability Scale (SUS) and Post-Study System Usability Questionnaire (PSSUQ), another two well-validated questionnaires, uMARS were then used to evaluate the usability of MH-NRES. The Cronbach alpha of the total score and the subscales of uMARS was calculated to evaluate the internal consistency. The correlation coefficients among three questionnaires were calculated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>In this study, 118 anesthesiologists provided responses to the questionnaire. The overall mean uMARS score was 4.43\u2009\u00b1\u20090.61, which ranged from 3 to 5. The mean PSSUQ score were in good to excellent range with mean of 6.02\u2009\u00b1\u20090.97, which ranged from 3.19 to 7. The overall SUS score was 76.0\u2009\u00b1\u200917.6, which ranged from 45 to 100. The total uMARS score had excellent internal consistency (Cronbach alpha\u2009=\u20090.984). uMARS and its subscales were strongly correlated with PSSUQ (coefficient 0.758\u20130.819, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and SUS (coefficient 0.535\u20130.561, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), respectively.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Data obtained from the usability evaluation questionnaires in this study indicated a high quality of the MH-NRES on the ease of use, satisfaction and perceived usefulness, which suggest this system might be a useful tool for anesthesiologists\u2019 education and management of MH crises.
