Circadian rhythm measured by step count in patients undergoing midline laparotomy for gynaecological conditions

Abstract

AbstractObjectiveWe 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.
