Assessing the quality of reporting of studies using Vascular Quality Initiative (VQI) data.

OBJECTIVE: The Society for Vascular Surgery Vascular Quality Initiative (VQI) has become an increasingly popular data source for retrospective observational vascular surgery studies. There are published guidelines on the reporting of data in such studies to promote transparency and rigor, but these have not been used to evaluate studies using VQI data. Our objective was to appraise the methodological reporting quality of studies using VQI data by evaluating their adherence to these guidelines. METHODS: The Society for Vascular Surgery VQI publication repository was queried for all articles published in 2020. The REporting of studies Conducted using Observational Routinely-collected Health Data (RECORD) statement and the Journal of American Medical Association-Surgical Section (JAMA-Surgery) checklist were utilized to assess the quality of each article's reporting. Five and three items from the RECORD statement and JAMA-Surgery checklist were excluded, respectively, because they were either inapplicable or nonassessable. Journal impact factor (IF) was queried for each article to elucidate any difference in reporting standards between high and low IF journals. RESULTS: Ninety studies were identified and analyzed. The median score on the RECORD checklist was 6 (of 8). The most commonly missed item was discussing data cleaning methods (93% missed). The median score on the JAMA-Surgery checklist was 3 (of 7). The most commonly missed items were the identification of competing risks (98% missed), the use of a flow chart to clearly define sample exclusion and inclusion criteria (84% missed), and the inclusion of a solid research question and hypothesis (81% missed). There were no differences in JAMA-Surgery checklist or RECORD statement median scores among studies published in low vs high IF journals. CONCLUSIONS: Studies using VQI data demonstrate a poor to moderate adherence to reporting standards. Key areas for improvement in research reporting include articulating a clear hypothesis, using flow charts to clearly define inclusion and exclusion criteria, identifying competing risks, and discussing data cleaning methods. Additionally, future efforts should center on creating tailored instruments to better guide reporting in studies using VQI data.

National Institutes of Health funding among vascular surgeons is rare.

BACKGROUND: The National Institutes of Health (NIH) is an essential source of funding for vascular surgeons conducting research. NIH funding is frequently used to benchmark institutional and individual research productivity, help determine eligibility for academic promotion, and as a measure of scientific quality. We sought to appraise the current scope of NIH funding to vascular surgeons by appraising the characteristics of NIH-funded investigators and projects. In addition, we also sought to determine whether funded grants addressed recent Society for Vascular Surgery (SVS) research priorities. METHODS: In April 2022, we queried the NIH Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER) database for active projects. We only included projects that had a vascular surgeon as a principal investigator. Grant characteristics were extracted from the NIH Research Portfolio Online Reporting Tools Expenditures and Results database. Principal investigator demographics and academic background information were identified by searching institution profiles. RESULTS: There were 55 active NIH awards given to 41 vascular surgeons. Only 1% (41/4037) of all vascular surgeons in the United States receive NIH funding. Funded vascular surgeons are an average of 16.3 years out of training; 37% (n = 15) are women. The majority of awards (58%; n = 32) were R01 grants. Among the active NIH-funded projects, 75% (n = 41) are basic or translational research projects, and 25% (n = 14) are clinical or health services research projects. Abdominal aortic aneurysm and peripheral arterial disease are the most commonly funded disease areas and together accounted for 54% (n = 30) of projects. Three SVS research priorities are not addressed by any of the current NIH-funded projects. CONCLUSIONS: NIH funding of vascular surgeons is rare and predominantly consists of basic or translational science projects focused on abdominal aortic aneurysm and peripheral arterial disease research. Women are well-represented among funded vascular surgeons. Although the majority of SVS research priorities receive NIH funding, three SVS research priorities are yet to be addressed by NIH-funded projects. Future efforts should focus on increasing the number of vascular surgeons receiving NIH grants and ensuring all SVS research priorities receive NIH funding.

Limited health literacy is common among vascular surgery patients.

BACKGROUND: Health literacy is a crucial aspect of informed decision-making, and limited health literacy has been associated with worse health care outcomes. To date, health literacy has not been examined in vascular surgery patients. Therefore, we conducted a prospective observational study to determine the prevalence and factors associated with poor health literacy in vascular surgery patients. METHODS: The Newest Vital Sign (Pfizer, New York, NY), a validated instrument, was used to appraise the health literacy of 150 patients who visited the outpatient vascular clinic at UF Health Shands Hospital between April 2022 and August 2022. Patients who scored a 4 (out of 6) or higher were classified as having adequate health literacy. Each study participant also completed a sociodemographic questionnaire. RESULTS: In total, 82 out of the 150 (54%) patients we screened had limited health literacy. The prevalence of limited health literacy varied and was independently associated with increased age (odds ratio 1.06; 95% [1.02 to 1.10], P = .004), having not attended college (high school diploma versus college+ odds ratio 3.5; 95% [1.26 to 10.1], P = .018), and African American race (odds ratio 5.3; 95% [1.59 to 22.3], P = .012). A total of 83% of African American patients had limited health literacy, compared to 49% of Asian and White patients. CONCLUSION: Most vascular surgery patients have limited health literacy. Increased age, fewer years of education, and African American race were associated with limited health literacy. Physicians caring for patients with lower health literacy should investigate and use communication strategies tailored to patients with limited health literacy.
