Methods
The study cohort was derived from the Nationwide Inpatient Sample (NIS) database from 1998 through 2010, a subset of the Healthcare Cost and Utilization Project sponsored by the Agency for Healthcare Research and Quality. The NIS is the largest publicly available all-payer inpatient care database in the United States, including data on approximately 7 million to 8 million discharges per year, and is a stratified sample designed to approximate a 20% sample of US community (nonfederal,
Results
Table 1 shows baseline characteristics of the study population. A total of 665 VSM procedures were available for analysis from 1998 to 2010. The mean age of the study cohort was 56.9 ± 0.6 years. Men constituted 40% of the cohort, with 52.8% being white. The mean CCI score for the cohort was calculated as 0.87 ± 0.04, with hypertension being the most common co-morbidity, present in 45.1% of the patients, while diabetes was present in 12.2% of those who underwent VSM. Most procedures were done
Discussion
Our study presents valuable real-world postprocedural data regarding VSM from the largest available inpatient care database. Postoperative mortality after VSM was noted to be high at 5.9% in our study on the basis a wide spectrum of real-world VSM experience from multiple community hospitals across the nation. Although earlier publications have reported similar13 and higher14 mortality rates, improving surgical experience has resulted in reductions in postoperative mortality and complication
