Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose: To assess the incidence and time course of symptomatic venous thromboembolism (VTE) events in patients during and following hospitalization for major orthopedic or abdominal surgery. Methods: Data were extracted from the Thomson Reuters MarketScan(®) Inpatient Drug Link File for surgical patients admitted between January 2005 and December 2008. The analysis included 8989 abdominal surgery patients and 4220 orthopedic surgery patients. The cumulative risks of VTE and VTE hazard were assessed over a 180-day evaluation period after the hospital admission date, using Kaplan-Meier analysis and LOESS regression, respectively. Results: In total, 305 (2.3%) patients experienced a symptomatic VTE event. These were most frequent during days 1-9 (78 events) and 10-19 (72 events). In all, 64% of events occurred after discharge. Venous thromboembolism hazard peaked at approximately 1.3 per 1000 person-days (day 8) following orthopedic surgery and at approximately 0.52 per 1000 person-days (day 11) following abdominal surgery. In-hospital pharmacologic prophylaxis was received by 88.3% and 30.2% of orthopedic and abdominal surgery patients, respectively, whereas pharmacologic prophylaxis following hospitalization was received by 41.3% and 3.0% of patients, respectively. Conclusions: The time course of VTE in major surgery patients suggests that VTE risk is highest during the first 19 days after admission and that considerable VTE risk extends into the period after discharge.
