– A patient with a nontraumatic vascular emergency is significantly less likely to die today than a decade ago, with few exceptions, according to a new national analysis looking at 10 years of data. Unsurprisingly, endovascular surgery rates climbed over the study period, as did rates of acute limb ischemia, said Todd Vogel, MD, who discussed the study at the annual meeting of the Midwestern Vascular Surgical Society.

With an objective of evaluating trends for management of nontraumatic vascular emergencies in the United States, Dr. Vogel, who is chief of vascular and endovascular surgery at the University of Missouri–Columbia, and his colleagues examined frequencies of vascular emergencies, mortality rates, and how open versus endoscopic procedure technique affected the data.

To do this, the investigators used the U.S. National Inpatient Sample from 2005 to 2014 to identify nontraumatic vascular emergencies.

Using ICD-9 clinical management diagnosis and procedure codes allowed the investigators to capture a wide array of vascular emergencies, Dr. Vogel said. These included ruptured abdominal, thoracic, and thoracoabdominal aortic aneurysms (rAAAs, rTAAs, and rTAAAs, respectively), as well as acute limb ischemia, acute mesenteric ischemia, and ruptured visceral artery aneurysms.

Among the outcomes analyzed in the study were a trend analysis looking at how outcomes changed over time and an analysis of in-hospital mortality. Dr. Vogel and his colleagues also examined hospital resource utilization including length of stay and total hospital cost, inflation adjusted to 2014 costs.

The prevalence of endovascular intervention increased sharply over the study period, as one would expect, Dr. Vogel said. “At the beginning, we had about 24% of patients getting endovascular intervention for vascular emergencies, and currently, it’s 36%.” (P for trend, less than .0001).

Mortality dropped steeply overall, with overall mortality going from 13.80% to 9.14% during the study period (P less than .0001). Much of this decrease could be attributed to mortality for open procedures decreasing by over a third, from 16.5% to 10.7%, over the study period (P less than .0001). Endovascular procedure–related mortality decreased from 8.3% to 7.9% (P = .03).

Ruptured abdominal and thoracic aortic aneurysms were much less likely to be fatal in 2014 than in 2005. The overall mortality rate for rAAA went from 41.4% to 27.6% (P less than .0001) and rates for rTAAs dropped overall from 41.2% to 23.0% (P = .002).

However, endovascular rTAA repair mortality jumped from 14.9% to 27.4% (P = .0003) while mortality for open procedures plummeted from 51.3% to 16.7% (P less than .0001).

In-hospital mortality for some conditions didn’t change much over time: rTAAA mortality, for example, increased, but by a nonsignificant amount (44.7% vs. 47.6%; P = .06). “Mortality rates for rTAAA have remained static, despite the advances in treatment,” Dr. Vogel said.

Discussing these “concerning” results, Dr. Vogel noted that the increase in mortality “suggests an increased use of endovascular repair on higher-risk patients.” The mortality rate for ruptured visceral artery aneurysms did not change significantly either (16.7% vs. 6.7%, P = .09).

Overall, patients were 44% female and 66% white. “Over half of the patients were aged 70 or greater,” he said.

Acute limb ischemia was by far the most common vascular emergency, accounting for 82.4% of the total. Next most common were rAAAs, which made up just 10.79% of the vascular emergencies studied.

Looking at hospitalization trends over time, acute limb ischemia showed a slight trend up over the study period, from an occurrence rate of about 8.2 per 100,000 individuals at the beginning to about 9.0 per 100,000 by 2014.

Acute mesenteric ischemia also trended up, from an occurrence rate of about 4 per 1 million individuals in 2005 to about 6 per 1 million in 2014; rAAAs trended down, from about 13 per 1 million to a little over 9 per 1 million over the study period.

Among the other vascular emergencies incurring hospitalization, rTAAAs and ruptured visceral artery aneurysms were both rare, occurring in fewer than 7 per 10 million individuals, but both showed a slight upward trend over the study period. Slightly more common were rTAAs, which occurred at a rate of about 12 per 10 million individuals at the beginning of the study period and at slightly less than 15 per 10 million by the end.

Looking at hospital resource utilization, length of stay dropped significantly (P less than .004), but costs, unsurprisingly, increased over the study period, from about $25,000 to about $30,000 per occurrence (P less than .0001).

“The overall frequency of vascular emergencies has significantly increased over time,” Dr. Vogel said, “but in subgroup analysis ruptured abdominal [aortic] aneurysms are decreasing.” As endovascular procedures have increased, “The overall mortality has decreased, so we actually are doing better.” Some of this drop “may be due to improved perioperative care” as well as the increase in endovascular utilization, he noted.

In sum, though mortality has generally improved as endovascular procedures have become more common in vascular emergencies, “increased implementation of endovascular repair may not always improve outcomes,” Dr. Vogel said, especially in the context of an increasingly complex and aging patient population.

Dr. Vogel reported no conflicts of interest and no outside sources of funding.

Opioids don’t treat pain better than ibuprofen after venous ablation surgery

– Compared with ibuprofen, opioid pain medication offered little benefit for pain control after venous ablation surgery, in the experience of one surgical center.

Sharing study results at a poster session at the annual meeting of the Midwestern Vascular Surgery Society, Jana Sacco, MD, and her colleagues found that patients who received opioid prescriptions after venous ablations did not have significantly different postsurgical pain than did those who received ibuprofen alone.

The study, conducted against the national backdrop of greater scrutiny of postsurgical opioid prescribing, was the first to look at post–venous ablation pain management strategies, said Dr. Sacco, a resident physician at Henry Ford Hospital, Detroit. Venous ablation surgery can improve quality of life for patients with varicose veins, but best practices for managing postprocedure discomfort had not been clear; some patients receive opioid pain medications, while others are directed to use ibuprofen as needed for pain control.

The retrospective, single-center study assessed pre- and postoperative pain for patients undergoing venous ablation procedures over a 2-year period, said Dr. Sacco.

Patients who were prescribed opioids were compared with patients who were simply asked to take ibuprofen for pain control.

Comparing preoperative to postoperative pain scores, Dr. Sacco and her colleagues defined a change of 2-3 points on a 0-10 Likert scale as “good” improvement; a change of 1 point was defined as “mild” improvement, and no change or worsening was defined as no improvement.

Of the 268 patients for whom postoperative follow-up data were available, 142 received opioid prescriptions, while 126 did not.

Across the entire group of patients studied, those who had moderate to severe preoperative pain had significant improvement in pain after their procedures.

Whether patients received opioid pain medication after their venous ablation was not correlated with the degree of improvement in postprocedure pain scores. Of those who saw no improvement, 30 patients (45%) received opioids and 36 (55%) did not. Of the 89 patients who saw mild postprocedure improvement in pain, 35 (40%) were not discharged on opioids, and of 65 patients who had good improvement in postprocedure pain, 44% were not discharged on opioids (P = .7 for difference across groups).

When Dr. Sacco and her fellow researchers examined such patient characteristics as sex, race, body mass index, smoking status, and CEAP venous severity classification, they did not see any significant differences in pain scores. Similarly, neither the type of procedure (radiofrequency or laser ablation) nor information on whether compression treatment was used was associated with a difference in pain scores.

Dr. Sacco and her coauthors noted that the study was limited by its retrospective nature and the fact that patients were all drawn from a single institution. Additionally, the investigators were only able to ascertain whether opioids had been prescribed, not whether – or how much – medication was actually taken by patients.

“Most patients report an improvement in symptoms after undergoing vein ablation procedures,” reported Dr. Sacco and her colleagues, and most patients also do well with nonopioid pain control regimens. “Overprescribing opioids exposes patients to the risk of narcotic overdose and chronic opioid use and should be used with caution for patients undergoing vein ablation surgery,” they wrote.

Dr. Sacco reported no outside sources of funding and no conflicts of interest.

Vascular programs without NIVL curriculum leave trainees feeling unprepared

– Many vascular surgery trainees felt unprepared to take the Registered Physician in Vascular Interpretation (RPVI) exam, according to a recent survey. However, trainees in a program without a structured noninvasive vascular laboratory (NIVL) curriculum felt particularly unprepared, said Daisy Chou, MD.

“There is wide variation in NIVL experience amongst vascular surgery training programs,” noted Dr. Chou, a vascular surgery fellow at the Ohio State University, Columbus. She presented survey results at the annual meeting of the Midwestern Vascular Surgical Society. The survey constructed by Dr. Chou and her colleagues went out to trainees in both 0+5 and 5+2 vascular surgery training programs in September, 2017, in 114 unique programs.

Eventually, trainees from just over half of the programs responded (N = 61 programs, 53.5%), said Dr. Chou. Using responses from individual trainees, the authors grouped programs into one of two categories: those whose trainees felt well prepared for the RPVI, and those whose trainees felt unprepared for the RPVI.

In addition to a yes/no question about preparedness, the survey also asked whether training programs had a structured curriculum; respondents were asked to identify specific NIVL-related training activities. The survey asked about individual didactic components, as well as whether the trainee spent individual time with an attending physician and hands-on time with vascular technologists. Respondents were asked about the amount of time, measured in half days per week, spent in the vascular laboratory.

Finally, the survey asked whether trainees took a pre-RPVI exam review course, and whether they passed the RPVI exam on their first attempt.

Overall, 34 of the programs with respondents (55.7%) had structured curricula; the same number included lectures. Twenty programs (32.8%) provided video content, and 29 (47.5%) used textbooks. Just 18 programs (29.5%) assigned articles.

One-on-one time spent with an attending physician and focused on NIVL techniques was reported for 32 programs (52.5%). More programs (n = 37; 60.7%) provided trainees hands-on experience with vascular technologists.

Most programs (n = 32; 52.5%) had trainees spending less than one half day per week in the vascular laboratory, according to survey respondents.

In terms of preparedness, respondents for over half of the programs did not respond to the question asking whether they felt prepared for the RPVI, presumably because they had not yet taken the exam. This, acknowledged Dr. Chou, was a significant limitation of the survey. There was a timing problem: Trainees were surveyed at the start of the 2017-2018 academic year, but the RPVI exam isn’t usually taken until the end of the final year of training, with review courses taken not long before that.

Of the 32 programs with trainees who reported taking the RPVI exam, 18 had trainees who felt unprepared, and 14 program had trainees who felt well prepared. About a quarter of programs (N = 15; 24.6%) had trainees who took a review course prior to taking the exam.

Dr. Chou and her colleagues then examined the survey responses another way, seeing what differentiated the programs whose trainees felt well prepared from those with trainees who felt unprepared.

Statistically, the clear standout was whether the program had a structured curriculum: The 14 programs with a structured curriculum all had students who reported feeling well prepared. Just one-third of the 18 programs with unprepared students had a structured curriculum, which was a significant difference (P = .0001).

Also, programs that assigned articles and those that gave formal lectures were more likely to have students who felt prepared to sit for the RPVI exam (P = .002 and .004, respectively). A higher number of programs that gave trainees hands-on time with vascular technologists had trainees who felt prepared, but the difference wasn’t quite statistically significant (P = .05).

Having taken a review course prior to the exam was associated with feeling well prepared (P = .03).

Dr. Chou and her colleagues performed a logistic regression analysis to arrive at the educational components associated with the highest odds for trainees feeling well prepared. Lectures and articles came out on top in this analysis (odds ratios for feeling well prepared, 15.88 and 15.97, respectively). Hands-on time with vascular technologists had an odds ratio of 5.12 for feeling prepared.

Taking a review course boosted preparedness as well, with an odds ratio of 11.85 for feeling well prepared for the RPVI exam. This created a bit of a conundrum for the investigators, said Dr. Chou: “All well prepared programs had a structured NIVL curriculum, but most of their trainees still took an RPVI review course, so it’s unclear if the structured curriculum or the review course is responsible for trainees feeling well prepared for the RPVI exam,” she said.

An important caveat to the analysis of survey results, said Dr. Chou, is that “It’s unknown how these results will translate into pass rates.

“Vascular surgery leadership should not leave NIVL education to review courses,” said Dr. Chou. The ultimate goal, she said, should be to achieve expertise in the service of providing better patient care. To this end, Dr. Chou and her coauthors recommend that a structured NIVL curriculum be incorporated into vascular surgery training, and that the program include time spent with vascular technologists, a formal lecture-based component, and structured reading, as is provided by a journal club.

Dr. Chou reported no conflicts of interest, and no external sources of funding.

– Many vascular surgery trainees felt unprepared to take the Registered Physician in Vascular Interpretation (RPVI) exam, according to a recent survey. However, trainees in a program without a structured noninvasive vascular laboratory (NIVL) curriculum felt particularly unprepared, said Daisy Chou, MD.

“There is wide variation in NIVL experience amongst vascular surgery training programs,” noted Dr. Chou, a vascular surgery fellow at the Ohio State University, Columbus. She presented survey results at the annual meeting of the Midwestern Vascular Surgical Society. The survey constructed by Dr. Chou and her colleagues went out to trainees in both 0+5 and 5+2 vascular surgery training programs in September, 2017, in 114 unique programs.

Eventually, trainees from just over half of the programs responded (N = 61 programs, 53.5%), said Dr. Chou. Using responses from individual trainees, the authors grouped programs into one of two categories: those whose trainees felt well prepared for the RPVI, and those whose trainees felt unprepared for the RPVI.

In addition to a yes/no question about preparedness, the survey also asked whether training programs had a structured curriculum; respondents were asked to identify specific NIVL-related training activities. The survey asked about individual didactic components, as well as whether the trainee spent individual time with an attending physician and hands-on time with vascular technologists. Respondents were asked about the amount of time, measured in half days per week, spent in the vascular laboratory.

Finally, the survey asked whether trainees took a pre-RPVI exam review course, and whether they passed the RPVI exam on their first attempt.

Overall, 34 of the programs with respondents (55.7%) had structured curricula; the same number included lectures. Twenty programs (32.8%) provided video content, and 29 (47.5%) used textbooks. Just 18 programs (29.5%) assigned articles.

One-on-one time spent with an attending physician and focused on NIVL techniques was reported for 32 programs (52.5%). More programs (n = 37; 60.7%) provided trainees hands-on experience with vascular technologists.

Most programs (n = 32; 52.5%) had trainees spending less than one half day per week in the vascular laboratory, according to survey respondents.

In terms of preparedness, respondents for over half of the programs did not respond to the question asking whether they felt prepared for the RPVI, presumably because they had not yet taken the exam. This, acknowledged Dr. Chou, was a significant limitation of the survey. There was a timing problem: Trainees were surveyed at the start of the 2017-2018 academic year, but the RPVI exam isn’t usually taken until the end of the final year of training, with review courses taken not long before that.

Of the 32 programs with trainees who reported taking the RPVI exam, 18 had trainees who felt unprepared, and 14 program had trainees who felt well prepared. About a quarter of programs (N = 15; 24.6%) had trainees who took a review course prior to taking the exam.

Dr. Chou and her colleagues then examined the survey responses another way, seeing what differentiated the programs whose trainees felt well prepared from those with trainees who felt unprepared.

Statistically, the clear standout was whether the program had a structured curriculum: The 14 programs with a structured curriculum all had students who reported feeling well prepared. Just one-third of the 18 programs with unprepared students had a structured curriculum, which was a significant difference (P = .0001).

Also, programs that assigned articles and those that gave formal lectures were more likely to have students who felt prepared to sit for the RPVI exam (P = .002 and .004, respectively). A higher number of programs that gave trainees hands-on time with vascular technologists had trainees who felt prepared, but the difference wasn’t quite statistically significant (P = .05).

Having taken a review course prior to the exam was associated with feeling well prepared (P = .03).

Dr. Chou and her colleagues performed a logistic regression analysis to arrive at the educational components associated with the highest odds for trainees feeling well prepared. Lectures and articles came out on top in this analysis (odds ratios for feeling well prepared, 15.88 and 15.97, respectively). Hands-on time with vascular technologists had an odds ratio of 5.12 for feeling prepared.

Taking a review course boosted preparedness as well, with an odds ratio of 11.85 for feeling well prepared for the RPVI exam. This created a bit of a conundrum for the investigators, said Dr. Chou: “All well prepared programs had a structured NIVL curriculum, but most of their trainees still took an RPVI review course, so it’s unclear if the structured curriculum or the review course is responsible for trainees feeling well prepared for the RPVI exam,” she said.

An important caveat to the analysis of survey results, said Dr. Chou, is that “It’s unknown how these results will translate into pass rates.
