Background Postoperative delirium is considered a serious complication in elderly patients. Elderly patients often suffer from several concomitant diseases. The reduced physical condition can increase the risk of cardiac, pulmonary and neurocognitive complications during and after surgery. SARS-CoV-2 infection primarily affects the respiratory tract but can also damage other organ systems such as the heart and brain. Given the wide range of pulmonary, cardiac and neurocognitive complications caused by SARS-CoV-2, these risks must be given special consideration during planned surgical procedures. Both surgical procedures and anesthesia are risk factors for postoperative complications in themselves. The specific impact of prior SARS-CoV-2 infection on perioperative complications in elderly patients has not been sufficiently researched. The aim of this study is to understand how a previous SARS-CoV-2 infection influences the occurrence of perioperative complications. Methods In this case-control study, the data of patients over 60 years of age undergoing elective surgery are analyzed. Subjects are divided into two groups based on their SARS-CoV-2 infection status: those with a documented previous infection and those without. Confirmation of infection will be based on written evidence and anamnestic information. The primary endpoint of the examination is the occurrence of delirium within the first five postoperative days. In addition, further cardiac, pulmonary and neurocognitive complications are recorded in the perioperative period. The occurrence of postoperative delirium is recorded during the daily ward round in the first five days after the operation. The 3DCAM test and the 4AT are used for this purpose. In addition, the CAM-ICU will be used in the intensive care unit. The recruitment will include 266 patients. Statistical analyses will be performed to determine the correlation between a previous SARS-CoV-2 infection and the observed clinical outcomes. Discussion The results of this study will provide new insights into the impact of prior SARS-CoV-2 infection on perioperative complications in elderly patients undergoing elective surgery.

Importance Cardiovascular and renal consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been studied intensively in high-risk groups, but the consequences of mild infection for the general population, particularly beyond the acute phase of infection, remain unclear. Objective To examine long-term associations between SARS-CoV-2 infection and cardiovascular and kidney disease (CVD, KD) in the general population, with emphasis on age and vaccination status at the time of infection, mild infection, and SARS-CoV-2 variant. Design Register-based cohort study. Setting Denmark Participants All Danish residents with ≥1 PCR test for SARS-CoV-2 infection, March 2020-December 2022. Exposure Positive PCR test for SARS-CoV-2 infection. Main Outcomes Hazard ratios for 15 CVD outcomes and six KD outcomes, comparing persons testing positive for SARS-CoV-2 infection and persons who only ever tested negative for infection. Results The cohort for CVD analyses included 4,508,489 persons without pre-existing CVD (median follow-up 25.2 months/person, interquartile range [IQR] 21.7-27.5 months); 2,698,261 persons (59.8%) tested positive for SARS-CoV-2 infection during the study period. The cohort for the KD analyses included 5,150,480 persons without pre-existing KD (median follow-up 25.1 months, IQR 21.7-27.4 months), 2,983,233 (57.9%) of whom tested positive for infection. SARS-CoV-2 infection was associated with slight increases in the risks of pulmonary embolism, venous embolism/thrombosis, arrhythmias, chronic renal failure, unspecified renal failure, and other/unspecified KD up to a year after infection; infection was not associated with the other disease groups tested. The strongest associations between SARS-CoV-2 infection and CVD and KD were observed among unvaccinated persons and persons infected with earlier (pre-omicron) variants. Conclusions and Relevance We found little evidence that infection with SARS-CoV-2 was associated with increased long-term risks of CVD or KD in the general population. Increased CVD risks associated with SARS-CoV-2 infection appeared limited to three outcomes (pulmonary embolism, venous embolism/thrombosis, arrhythmias) and the potential increases in risk were small. Our KD results also suggested that any persistent risks associated with SARS-CoV-2 infection were minimal; however, these findings need to be confirmed in other populations. Most importantly, in a largely vaccinated population, long-term CVD and KD risks differed little for omicron-infected and uninfected persons. Question Does SARS-CoV-2 infection increase the long-term risks of cardiovascular disease (CVD) or kidney disease (KD) in a general population cohort with predominantly mild infection? Findings In a cohort study of 4.5 million persons that compared SARS-CoV-2 test-positive and test-negative persons, relative risks were slightly increased for 6 of 21 CVD and KD outcomes up to 1 year after infection. Among vaccinated individuals and omicron-infected persons, existing associations diminished dramatically. Meaning In the general population, long-term increases in CKD and KD risks associated with infection were small, limited to a few outcomes, and attenuated with vaccination and the omicron variant. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study was funded by the Lundbeck Foundation. ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.
