Long-term health effects of past COVID-19 in adults having preoperative anesthesia evaluation

Long-Term Clinical and Health Effects of Previous COVID-19 in Patients Presenting for Preoperative Anesthesia Evaluation

Observational Elazıg Fethi Sekin Sehir Hastanesi · NCT07435805

This project will see if adults with a prior confirmed COVID-19 infection who come to a preoperative anesthesia clinic have lasting health problems that could affect anesthesia and surgery planning.

What this trial studies

This cross-sectional observational project enrolls adults (≥18 years) who report laboratory-confirmed prior COVID-19 and present to a preoperative anesthesia clinic. Clinical data on the acute infection (severity, hospitalization, ICU admission, oxygen therapy, imaging) and current symptoms are collected through chart review and a post-COVID clinical questionnaire. The work is single-center at Fethi Sekin City Hospital and involves no interventions beyond standard preoperative assessment and questionnaire completion. Analyses will describe the prevalence and patterns of residual symptoms and relate them to prior illness severity and perioperative risk factors.

Who should consider this trial

Good fit: Adults aged 18 or older who present to the preoperative anesthesia clinic, have a self-reported laboratory-confirmed history of COVID-19, can provide informed consent, and are willing to complete the post-COVID questionnaire.

Not a fit: Patients without prior COVID-19, those under 18, or those with cognitive or communication barriers preventing reliable questionnaire responses are unlikely to benefit from this study's findings.

Why it matters

Potential benefit: If successful, the findings could help anesthesiologists recognize residual effects of COVID-19 and personalize perioperative risk assessment to reduce complications.

How similar studies have performed: Many observational studies have documented persistent multisystem symptoms after COVID-19, but few have specifically examined how these sequelae affect preoperative anesthesia evaluation, making this focus relatively novel.
