Risk Prediction Models for Postoperative Decompensation and Infection in Patients With Cirrhosis: A Veterans Affairs Cohort Study.

ABSTRACT:

Background and aims

Patients with cirrhosis have an increased risk of postoperative mortality for a range of surgeries; however, they are also at risk of postoperative complications such as infection and cirrhosis decompensation. To date, there are no prediction scores that specifically risk stratify patients for these morbidities.

Methods

This was a retrospective study using data of patients with cirrhosis who underwent diverse surgeries in the Veterans Health Administration. Validated algorithms and/or manual adjudication were used to ascertain postoperative decompensation and postoperative infection through 90 days. Multivariable logistic regression was used to evaluate prediction models in derivation and validation sets using variables from the recently-published Veterans Outcomes and Costs Associated with Liver Disease (VOCAL)-Penn cirrhosis surgical risk scores for postoperative mortality. Models were compared with the Mayo risk score, Model for End-stage Liver Disease (MELD)-sodium, and Child-Turcotte-Pugh (CTP) scores.

Results

A total 4712 surgeries were included; patients were predominantly male (97.2 %), white (63.3 %), and with alcohol-related liver disease (35.3 %). Through 90 postoperative days, 8.7 % of patients experienced interval decompensation, and 4.5 % infection. Novel VOCAL-Penn prediction models for decompensation demonstrated good discrimination for interval decompensation (C-statistic 0.762 vs 0.663 Mayo vs 0.603 MELD-sodium vs 0.560 CTP; P < .001); however, discrimination was only fair for postoperative infection (C-statistic 0.666 vs 0.592 Mayo [P = .13] vs 0.502 MELD-sodium [P < .001] vs 0.503 CTP [P < .001]). The model for interval decompensation had excellent calibration in both derivation and validation sets.

Conclusion

We report the derivation and internal validation of a novel, parsimonious prediction model for postoperative decompensation in patients with cirrhosis. This score demonstrated superior discrimination and calibration as compared with existing clinical standards, and will be available at www.vocalpennscore.com.

Project description:Background & aimsStatins decrease portal pressure in patients with cirrhosis and increase survival times of patients who have bled from varices. However, statins can be hepatotoxic. It is important to determine whether long-term statin use will be beneficial or detrimental for patients with cirrhosis because physicians are reluctant to prescribe statins to patients with liver disease. We investigated the effects of statins on decompensation and survival times in patients with compensated cirrhosis.MethodsWe performed a retrospective cohort using the Veteran Affairs Clinical Case Registry, which contains nationwide data from veterans infected with the hepatitis C virus (HCV). We identified patients with compensated cirrhosis from January 1996 through December 2009. Statin use was according to filled prescriptions. Cirrhosis and decompensation were determined from International Classification of Diseases, 9th revision codes, using a validated algorithm.ResultsAmong 40,512 patients with HCV compensated cirrhosis (98% male; median age, 56 y), 2802 statin users were identified. We developed a propensity score model using variables associated with statin prescription, and new statin users were matched with up to 5 nonusers; 685 statin users were matched with 2062 nonusers. Discrimination of the propensity score model was 0.92. Statin users had a lower risk of decompensation (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.39-0.77) and death (HR, 0.56; 95% CI, 0.46-0.69), compared with nonusers. Findings persisted after adjustment for age, FIB-4 index score, serum level of albumin, model for end-stage liver disease and Child-Turcotte-Pugh scores (HR for decompensation, 0.55; 95% CI, 0.39-0.78), and death (HR, 0.55; 95% CI, 0.45-0.68).ConclusionsBased on data from the Veteran Affairs Clinical Case Registry, statin use among patients with HCV and compensated cirrhosis is associated with a more than 40% lower risk of cirrhosis decompensation and death. Although statins cannot yet be recommended widely for these patients, their use should not be avoided.

Project description:ImportanceMany veterans enrolled in the Veterans Affairs (VA) health care system have access to non-VA care through insurance and VA-purchased community care. Prior comparisons of VA and non-VA hospital outcomes have been limited to subpopulations.ObjectiveTo compare outcomes for 6 acute conditions in VA and non-VA hospitals for younger and older veterans using VA and all-payer discharge data.Design, setting, and participantsThis cohort study used a repeated cross-sectional analysis of hospitalization records for acute myocardial infarction (AMI), coronary artery bypass graft (CABG), gastrointestinal (GI) hemorrhage, heart failure (HF), pneumonia, and stroke. Participants included VA enrollees from 11 states at VA and non-VA hospitals from 2012 to 2017. Analysis was conducted from July 1, 2022, to October 18, 2023.ExposuresTreatment in VA or non-VA hospital.Main outcome and measuresThirty-day mortality, 30-day readmission, length of stay (LOS), and costs. Average treatment outcomes of VA hospitals were estimated using inverse probability weighted regression adjustment to account for selection into hospitals. Models were stratified by veterans' age (aged less than 65 years and aged 65 years and older).ResultsThere was a total of 593 578 hospitalizations and 414 861 patients with mean (SD) age 75 (12) years, 405 602 males (98%), 442 297 hospitalizations of non-Hispanic White individuals (75%) and 73 155 hospitalizations of non-Hispanic Black individuals (12%) overall. VA hospitalizations had a lower probability of 30-day mortality for HF (age ≥65 years, -0.02 [95% CI, -0.03 to -0.01]) and stroke (age <65 years, -0.03 [95% CI, -0.05 to -0.02]; age ≥65 years, -0.05 [95% CI, -0.07 to -0.03]). VA hospitalizations had a lower probability of 30-day readmission for CABG (age <65 years, -0.04 [95% CI, -0.06 to -0.01]; age ≥65 years, -0.05 [95% CI, -0.07 to -0.02]), GI hemorrhage (age <65 years, -0.04 [95% CI, -0.06 to -0.03]), HF (age <65 years, -0.05 [95% CI, -0.07 to -0.03]), pneumonia (age <65 years, -0.04 [95% CI, -0.06 to -0.03]; age ≥65 years, -0.03 [95% CI, -0.04 to -0.02]), and stroke (age <65 years, -0.11 [95% CI, -0.13 to -0.09]; age ≥65 years, -0.13 [95% CI, -0.16 to -0.10]) but higher probability of readmission for AMI (age <65 years, 0.04 [95% CI, 0.01 to 0.06]). VA hospitalizations had a longer mean LOS and higher costs for all conditions, except AMI and stroke in younger patients.Conclusions and relevanceIn this cohort study of veterans, VA hospitalizations had lower mortality for HF and stroke and lower readmissions, longer LOS, and higher costs for most conditions compared with non-VA hospitalizations with differences by condition and age group. There were tradeoffs between better outcomes and higher resource use in VA hospitals for some conditions.

Project description:Background & aimsThe impact of proton pump inhibitory (PPI) medications on adverse outcomes in cirrhosis remains controversial. We aimed to evaluate the association between PPI exposure and all-cause mortality, infection, and decompensation in a large national cohort.MethodsThis was a retrospective study of patients with cirrhosis in the Veterans Health Administration. PPI exposure was classified as a time-updating variable from the index time of the cirrhosis diagnosis. Inverse probability treatment weighting-adjusted Cox regression was performed with additional adjustment for key time-varying covariates, including cardiovascular comorbidities, gastrointestinal bleeding (GIB), and statin exposure.ResultsThe study included 76,251 patients, 23,628 of whom were on a PPI at baseline. In adjusted models, binary (yes/no) PPI exposure was associated with reduced hazard of all-cause mortality in patients with hospitalization for GIB (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.84-0.91; P < .001) but had no significant association in all others (HR, 0.99; 95% CI, 0.97-1.02; P = .58). However, cumulative PPI exposure was associated with increased mortality in patients without hospitalization for GIB (HR, 1.07 per 320 mg-months [omeprazole equivalents]; 95% CI, 1.06-1.08; P < .001). PPI exposure was significantly associated with severe infection (HR, 1.21; 95% CI, 1.18-1.24; P < .001) and decompensation (HR, 1.64; 95% CI, 1.61-1.68; P < .001). In a cause-specific mortality analysis, PPI exposure was associated with increased liver-related mortality (HR, 1.23; 95% CI, 1.19-1.28) but with decreased nonliver-related mortality (HR, 0.88; 95% CI, 0.85-0.91).ConclusionsPPI exposure is associated with increased risk of infection and decompensation in cirrhosis, which may mediate liver-related mortality. However, PPI use was associated with reduced all-cause mortality in those with prior GIB, suggesting benefit in the presence of an appropriate indication.
