Preoperative routine measurement of NT-proBNP predicts postoperative morbidity after non-cardiac surgery with intermediate or high surgical risk: an observational study.

ABSTRACT:

Background

Chronic heart failure (HF) is a common clinical condition associated with adverse outcomes in elderly patients undergoing non-cardiac surgery. This study aimed to estimate a clinically applicable NT-proBNP cut-off that predicts postoperative 30-day morbidity in a non-cardiac surgical cohort.

Methods

One hundred ninety-nine consecutive patients older than 65 years undergoing elective non-cardiac surgery with intermediate or high surgical risk were analysed. Preoperative NT-proBNP was measured, and clinical events were assessed up to postoperative day 30. The primary endpoint was the composite morbidity endpoint (CME) consisting of rehospitalisation, acute decompensated heart failure (ADHF), acute kidney injury (AKI), and infection at postoperative day 30. Secondary endpoints included perioperative fluid balance and incidence, duration, and severity of perioperative hypotension.

Results

NT-proBNP of 443 pg/ml had the highest accuracy in predicting the composite endpoint; a clinical cut-off of 450 pg/ml was implemented to compare clinical endpoints. Although 35.2% of patients had NT-proBNP above the threshold, only 10.6% had a known history of HF. The primary endpoint was the composite morbidity endpoint (CME) consisting of rehospitalisation, acute decompensated heart failure (ADHF), acute kidney injury (AKI), and infection. Event rates were significantly increased in patients with NT-proBNP > 450 pg/ml (70.7% vs. 32.4%, p < 0.001), which was due to the incidence of cardiac rehospitalisation (4.4% vs. 0%, p = 0.018), ADHF (20.1% vs. 4.0%, p < 0.001), AKI (39.8% vs. 8.3%, p < 0.001), and infection (46.3% vs. 24.4%, p < 0.01). Perioperative fluid balance and perioperative hypotension were comparable between groups. Preoperative NT-proBNP > 450 pg/ml was an independent predictor of the CME in a multivariable Cox regression model (hazard ratio 2.92 [1.72-4.94]).

Conclusions

Patients with NT-proBNP > 450 pg/ml exhibited profoundly increased postoperative morbidity. Further studies should focus on interdisciplinary approaches to improve outcomes through integrated interventions in the perioperative period.

Project description:BACKGROUND:Frailty is a frequent and underdiagnosed functional syndrome involving reduced physiological reserves and an increased vulnerability against stressors, with severe individual and socioeconomic consequences. A routine frailty assessment was implemented at our preoperative anaesthesia clinic to identify patients at risk. OBJECTIVE:This study examines the relationship between frailty status and the incidence of in-hospital postoperative complications in elderly surgical patients across several surgical disciplines. DESIGN:Retrospective observational analysis. SETTING:Single center, major tertiary care university hospital. Data collection took place between June 2016 and March 2017. PATIENTS:Patients 65 years old or older were evaluated for frailty using Fried's 5-point frailty assessment prior to elective non-cardiac surgery. Patients were classified into non-frail (0 criteria, reference group), pre-frail (1-2 positive criteria) and frail (3-5 positive criteria) groups. MAIN OUTCOME MEASURES:The incidence of postoperative complications was assessed until discharge from the hospital, using the roster from the National VA Surgical Quality Improvement Program. Propensity score matching and logistic regression analysis were performed. RESULTS:From 1186 elderly patients, 46.9% were classified as pre-frail (n = 556), and 11.4% as frail (n = 135). The rate of complications were significantly higher in the pre-frail (34.7%) and frail groups (47.4%), as compared to the non-frail group (27.5%). Similarly, length of stay (non-frail: 5.0 [3.0;7.0], pre-frail: 7.0 [3.0;9.0], frail 8.0 [4.5;12.0]; p < 0.001) and discharges to care facilities (non-frail:1.6%, pre-frail: 7.4%, frail: 17.8%); p < 0.001) were significantly associated with frailty status. After propensity score matching and logistic regression analysis, the risk for developing postoperative complications was approximately two-fold for pre-frail (OR 1.78; 95% CI 1.04-3.05) and frail (OR 2.08; 95% CI 1.21-3.60) patients. CONCLUSIONS:The preoperative frailty assessment of elderly patients identified pre-frail and frail subgroups to have the highest rate of postoperative complications, regardless of age, surgical discipline, and surgical risk. Significantly increased length of hospitalisation and discharges to care facilities were also observed. Implementation of routine frailty assessments appear to be an effective tool in identifying patients with increased risk. Now future studies are needed to investigate whether patients benefit from optimization of patient counselling, process planning, and risk reduction protocols based on the application of risk stratification.

Project description:Study designRetrospective review.ObjectiveCompare postoperative infection rates and 30-day outcomes in spine surgery patients with and without a preoperative urinary tract infection (UTI).Summary of background dataThere is mixed evidence regarding safety and risks when operating on spine patients with a preoperative UTI.MethodsUsing data from the American College of Surgeons National Surgical Quality Improvement Program, we identified all adult patients undergoing spine surgery between 2012 and 2017 with a preoperative UTI. Patients with other preoperative infections were excluded. Our primary outcome was any postoperative infection (pneumonia, sepsis, surgical site infection, and organ space infection). Our secondary outcomes included surgical site infections, non-infectious complications, return to operating room, and 30-day readmission and mortality. We used univariate, then multivariate Poisson regression models adjusted for demographics, comorbidities, laboratory values, and case details to investigate the association between preoperative UTI status and postoperative outcomes.ResultsA total of 270,371 patients who underwent spine surgery were analyzed. The most common procedure was laminectomy (41.9%), followed by spinal fusion (31.7%) and laminectomy/fusion (25.6%). Three hundred fourty one patients had a preoperative UTI (0.14%). Patients with a preoperative UTI were more likely to be older, female, inpatients, emergency cases, with a higher American Society of Anesthesiologists score, and a longer operating time (for all, P < 0.001). Patients with a preoperative UTI had higher rates of infectious and non-infectious complications, return to operating room, and unplanned readmissions (for all, P < 0.001). However, there was no significant difference in mortality (0.6% vs. 0.2%, P = 0.108). Even after controlling for demographics, comorbidities, labs, and case details, preoperative UTI status was significantly associated with more postoperative infectious complications (incidence rate ratio [IRR]: 2.88, 95% confidence interval [CI]: 2.25-3.70, P < 0.001).ConclusionPreoperative UTI status is significantly associated with postoperative infections and worse 30-day outcomes. Spine surgeons should consider delaying or cancelling surgery in patients with a UTI until the infection has cleared to reduce adverse outcomes.Level of evidence3.
