Behaviours of older adults and caregivers preparing for elective surgery: a virtually conducted mixed-methods research protocol to improve surgical outcomes

Posted: 2021-10-19 19:00:00
Introduction: Older adults (age ≥65 years) are pursuing increasingly complex, elective surgeries; and, are at higher risk for intraoperative and postoperative complications. Patients and their caregivers frequently struggle with the postoperative recovery process at home, which may contribute to complications. We aim to identify opportunities to intervene during the preoperative period to improve postoperative outcomes by understanding the preparatory behaviours of older adults and their caregivers before a complex, elective surgery. Methods and analysis: As a result of the COVID-19 pandemic, we will conduct this study via telephone and videoconferencing. Using a multiphase mixed-methods research design, we will collect data on 10-15 patient-caregiver dyads from a pool of older adults (across a spectrum of cognitive abilities) scheduled for an elective colorectal surgery between 1 July 2020 and 30 May 2021. We will collect quantitative and qualitative data before (T1, T2) and after (T3, T4) surgery. Preoperatively, participants will each complete a cognitive assessment and a semi-structured qualitative interview that focuses on their preparatory behaviours (T1). They will then answer questionnaires about mood, self-efficacy and home environment (T2). Three weeks following hospital discharge, participants will complete another qualitative interview focusing on a comparison of preoperative and postoperative preparedness (T3). Researchers will also collect information about the patient's medical conditions, the postoperative complications and healthcare utilisation from the patient's chart 30 days following discharge (T4). We will code and conduct thematic analysis of the qualitative data to identify salient themes. Quantitative data will be analysed using basic descriptive statistics to characterise the participants. We will integrate the qualitative and quantitative findings using results from the quantitative scales to group participants and with use of joint display analysis. Ethics and dissemination: Ethics approval was obtained from the University of Michigan IRB. Study findings will be disseminated through peer-reviewed journals and presentations at conferences. Keywords: adult surgery; colorectal surgery; geriatric medicine; qualitative research; statistics & research methods.

テルアビブ大学の研究者らによると、遺伝子変異PiZまたはPiSの保因者は、重度の病気や COVID-19 による死亡のリスクが高いことを示唆している。 これらの変異は、重度の感染症の場合に肺組織を損傷から保護するα1-アンチトリプシンタンパク質の欠損に繋がっているという。他の研究では、このタンパク質の欠乏が他の疾患の肺機能への炎症性損傷と関連していることがすでに知られている。 この研究は、テルアビブ大学サックラー医学部のDavid Gurwitz教授、Noam Shomron教授および修士課程候補のGuy…
