To compare the impact of obesity on perioperative outcomes between open radical prostatectomy (ORP) and minimally invasive prostatectomy (MIP).
Using the National Surgical Quality Improvement Program (NSQIP) public use files for 2008-2013, we identified patients undergoing prostatectomy using current procedural terminology codes. Those without BMI or comorbidity information were excluded. BMI was treated as a categorical variable according to the World Health Organization classification. Demographic and comorbid conditions were compared between BMI groups and multivariable logistical regression was used to identify independent predictors of adverse perioperative events.
We identified 17,693 MIP and 4,674 ORP for analysis. Of the entire cohort, only 18.7% had a BMI within the normal range (18.5-24.9), while the remaining 81.3% were at least overweight (BMI>25). Class I, II, and III obesity accounted for 25.0%, 7.0% and 2.3% of the cohort; respectively. Overall, complications were higher with ORP (19.0%) than MIP (5.3%), which held true across all BMI categories. The rate of wound, renal, thromboembolic, infectious, neurologic, Clavien grade III-V, and overall complications among MIP were directly related to BMI. Only wound and renal complications were related to BMI in ORP. In multivariable analysis obesity was found to be an independent predictor of wound, renal and thromboembolic complications.
Obesity has a larger impact on morbidity for MIP compared to ORP. Overall morbidity, however, remains lower for MIP across all BMI groups.
This research output has an Altmetric Attention Score of 3. 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 10 January 2017.
All research outputs
#17,018,570
of 29,014,077 outputs
Outputs from Urology
#5,994
of 9,073 outputs
Outputs of similar age
#217,682
of 418,257 outputs
Outputs of similar age from Urology
#53
of 192 outputs
Altmetric has tracked 29,014,077 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,073 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 33rd percentile – i.e., 33% 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 418,257 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 192 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
