ObjectiveWe aimed to investigate the circadian rhythm of patients undergoing gynaecological surgery using activity log data. MethodsThis is a planned secondary analysis of a randomised controlled trial dataset. The randomised controlled trial included 53 women undergoing midline laparotomy for gynaecological conditions (NCT02025387). A detailed activity log (number of steps per minute) was collected from 10 patients using a wearable activity tracker (Lifegram LA11M-BS, LG). The activity log data of the patients (N=10) were visualised by a pandas 1.4.2 documentation using google colab. ResultsPatients walked more during the day than at night, indicating a preserved circadian rhythm. Daily post-operative activity increased with the progress of the post-operative day. Nocturnal activity increased from postoperative day 3. ConclusionPostoperative activities of women who underwent midline laparotomy showed a preserved circadian rhythm.
