Abstract

The Model for End-Stage Liver Disease (MELD) score and ascites correlate with surgical morbidity and mortality. However, the MELD score does not account for ascites. We sought to evaluate whether the MELD score accurately risk stratifies patients with ascites. We analyzed the American College of Surgeons National Surgical Quality Improvement Program (2005-2014) to examine the risk-adjusted morbidity and mortality of cirrhotic patients with and without ascites undergoing colectomy for diverticulitis. Patients were stratified by MELD score, and the presence of ascites and outcomes were compared between patients with and without ascites to the reference group of low MELD and no ascites. Multivariable logistic regression was used to control for demographic factors and comorbidities. A total of 16,877 colectomies were analyzed. For each MELD stratum, patients with ascites have increased risk of complications compared to those without ascites (P < 0.05 unless indicated): low MELD ascites OR 1.13, P = 0.69, moderate MELD no ascites OR 1.37, moderate MELD ascites OR 2.06, high MELD no ascites OR 1.93, and high MELD ascites OR 3.54. These trends hold true for mortality: low MELD ascites OR 2.91, P = 0.063, moderate MELD no ascites OR 1.47, moderate MELD ascites OR 5.62, high MELD no ascites OR 3.04, and high MELD ascites OR 9.91. Ascites predicts an increased risk for postoperative morbidity and mortality for cirrhotic patients undergoing colectomy for all MELD classifications. These findings suggest that the MELD score significantly underestimates postoperative risk as it does not account for ascites.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 July 2018.
All research outputs
#14,378,457
of 23,028,364 outputs
Outputs from World Journal of Surgery
#2,793
of 4,262 outputs
Outputs of similar age
#189,798
of 333,763 outputs
Outputs of similar age from World Journal of Surgery
#65
of 89 outputs
Altmetric has tracked 23,028,364 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,262 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one is in the 31st percentile – i.e., 31% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 333,763 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 89 others from the same source and published within six weeks on either side of this one. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
