ABSTRACT

Importance: There is a lack of consensus regarding the interval of time-dependent postoperative mortality risk following acute coronary syndrome or stroke. Objective: To determine the magnitude and duration of risk associated with the time interval between a preoperative cardiovascular event and 30-day postoperative mortality. Design, Setting, and Participants: This is a longitudinal retrospective population-based cohort study. This study linked data from the Hospital Episode Statistics for National Health Service England, Myocardial Ischaemia National Audit Project and the Office for National Statistics mortality registry. All adults undergoing a National Health Service-funded noncardiac, nonneurologic surgery in England between April 1, 2007, and March 31, 2018, registered in Hospital Episode Statistics Admitted Patient Care were included. Data were analyzed from July 2021 to July 2022. Exposure: The time interval between a previous cardiovascular event (acute coronary syndrome or stroke) and surgery. Main Outcomes and Measures: The primary outcome was 30-day all-cause mortality. Secondary outcomes were postoperative mortality at 60, 90, and 365 days. Multivariable logistic regression models with restricted cubic splines were used to estimate adjusted odds ratios. Results: There were 877 430 patients with and 20 582 717 without a prior cardiovascular event (overall mean [SD] age, 53.4 [19.4] years; 11 577 157 [54%] female). Among patients with a previous cardiovascular event, the time interval associated with increased risk of postoperative mortality was surgery within 11.3 months (95% CI, 10.8-11.7), with subgroup risks of 14.2 months before elective surgery (95% CI, 13.3-15.3) and 7.3 months for emergency surgery (95% CI, 6.8-7.8). Heterogeneity in these timings was noted across many surgical specialties. The time-dependent risk intervals following stroke and myocardial infarction were similar, but the absolute risk was greater following a stroke. Regarding surgical urgency, the risk of 30-day mortality was higher in those with a prior cardiovascular event for emergency surgery (adjusted hazard ratio, 1.35; 95% CI, 1.34-1.37) and an elective procedure (adjusted hazard ratio, 1.83; 95% CI, 1.78-1.89) than those without a prior cardiovascular event. Conclusions and Relevance: In this study, surgery within 1 year of an acute coronary syndrome or stroke was associated with increased postoperative mortality before reaching a new baseline, particularly for elective surgery. This information may help clinicians and patients balance deferring the potential benefits of the surgery against the desire to avoid increased mortality from overly expeditious surgery after a recent cardiovascular event.

ABSTRACT

INTRODUCTION: An increasing number of people who have a history of acute coronary syndrome or cerebrovascular accident (termed cardiovascular events) are being considered for surgery. Up-to-date evidence of the impact of these prior events is needed to inform person-centred decision making. While perioperative risk for major adverse cardiac events immediately after a cardiovascular event is known to be elevated, the duration of time after the event for which the perioperative risk is increased is not clear. METHODS AND ANALYSIS: This is an individual patient-level database linkage study of all patients in England with at least one operation between 2007 and 2017 in the Hospital Episode Statistics Admitted Patient Care database. Data will be linked to mortality data from the Office for National Statistics up to 2018, for 30-day, 90-day and 1-year mortality and to the Myocardial Ischaemia National Audit Project, a UK registry of acute coronary syndromes. The primary outcome will be the association between time from cardiovascular event to index surgery and 30-day all-cause mortality. Additional associations we will report are all unplanned readmissions, prolonged length of stay, 30-day hospital free survival and incidence of new cardiovascular events within one postoperative year. Important subgroups will be surgery specific (invasiveness, urgency and subspecialty), type of acute coronary syndrome (ST or non-ST elevation myocardial infarction) and type of cerebrovascular accident (ischaemic or haemorrhagic stroke). ETHICS AND DISSEMINATION: Ethical approval for this observational study has been obtained from East Midlands-Nottingham 1 Research Ethics Committee; REC reference: 18/EM0403. The results of the study will be made available through peer-reviewed publications and via the Health Services Research Centre of the Royal College of Anaesthetists, London.

ABSTRACT

A 42-year-old woman presented to our hospital with weeks of worsening pain around her lower ribs. Preceding this, she was managed in primary care with anti-inflammatory drugs and physiotherapy for presumed costochondritis. Assessment in accident and emergency suggested a tender right upper quadrant with fever and neutrophilia. A surgical review of the patient was requested to assess for cholecystitis or delayed pancreatitis. On direct questioning, the patient's back pain was the predominating symptom with no neurological deficit. To assess for delayed pancreatitis, CT imaging was obtained, demonstrating unremarkable intra-abdominal organs. There was also the incidental finding of thickened prevertebral soft tissues anterior to T9 and T10 vertebrae, with vertebral endplate irregularity locally. Subsequent MRI demonstrated typical appearances of infective spondylodiscitis at this level. The patient made a good recovery with intravenous antimicrobials. This case highlights how vertebrodiscitis can present insidiously and unexpectedly, manifesting as abdominal pain.
