RESUMEN
OBJECTIVES: Patency for chronic total occlusions (CTO) of the superficial femoral artery (SFA) after endovascular interventions traditionally demonstrate a low 1-year patency ranging from 40%-60%. The optical coherence tomography (OCT) catheter (Avinger Inc., Redwood City, CA) uses light-based technology imaging to cross Trans-Atlantic Inter-Society Consensus D (TASC D) lesions intraluminally with direct intra-arterial visualization. Insufficient data exist evaluating intraluminal crossing with OCT imaging compared with traditional subintimal techniques. We evaluated outcomes for TASC D lesions crossed intraluminally. METHODS: A retrospective analysis of patients with SFA TASC D lesions crossed intra-arterially with the OCT catheter imaging. Descriptive statistics evaluated patient characteristics which included patient demographics, Rutherford scores, ABIs, CTA information, lesion categorization, as well as runoff score. Patency at baseline, 30-day, 6-month, and 1-year outcomes were compared using t-tests. Cumulative patency rates were evaluated using Kaplan-Meier analysis. RESULTS: 101 patients underwent elective intervention for SFA TASC D lesions with the OCT catheter. The crossing rate was 78.2%, mean lesion length was 16.2 cm, and runoff at the tibial level was 2.2 patent vessels. Mean age and BMI were 64 years and 29 kg/m2, respectively. Patient characteristics are male (57%); Caucasian (90%); ever smoking (85%); hypertension (82%), hyperlipidemia (70%), and diabetes (46%). Pre-operative computed tomography demonstrated SFA lesions were predominantly eccentric (91%) with mild to moderate calcification (90%). All underwent PTA, 87% were stented (mean stent length: 186.1 mm), mean crossing time was 13.4 min. Pre-operative, 30-day, 6-month, and 1-year post-operative mean Rutherford-Becker scores were 4, 1, 1, and 1, respectively (p < 0.0001). Mean pre-operative ABI was 0.49, compared to 0.84 at 30 days, 0.64 at 6 months, and 0.67 at 1 year (p < .0001). Duplex demonstrated 6- and 12-month primary patency of 89% and 75%; primary-assisted patency was 94% and 84%. CONCLUSIONS: The OCT imaging catheter successfully crossed long chronic total occlusions of the SFA using direct intra-arterial imaging. Compared to subintimal techniques, patients had high 1-year primary patency and prolonged symptom improvement with intraluminal crossing. These data suggest that intraluminal crossing of TASC D lesions may be superior to traditional subintimal crossing techniques.
RESUMEN
INTRODUCTION: Failure to Rescue (FTR), defined as mortality following a complication of care, is an important indicator of hospital care quality. Understanding risk factors associated with FTR in the elective Abdominal Aortic Aneurysm (AAA) population may help surgeons prevent operative mortality. METHODS: Elective open AAA repairs (2008-2018) were identified from Cerner's HealthFacts database using ICD-9 and ICD-10 diagnosis and procedure codes. Patient, hospital, and encounter characteristics were analyzed. Multivariate logistic regression models determined the relative contribution of patient and encounter characteristics leading to FTR. RESULTS: For 1761 patients who underwent open repair for nonruptured AAA, overall mortality was 6.1%. Of patients with one or more complications (40%), mortality was 9.6%, increasing to 21.5% for patients with ≥4 major complications. Complications of care most associated with death were myocardial infarction (MI), gastrointestinal (GI) bleeding, and pulmonary failure. After multivariable adjustment, FTR was associated with advanced age (odds ratio [OR] 1.19 for 5 y, 95% confidence interval [CI] 1.06-1.34); female sex (OR 1.74, 95% CI 1.12-2.70); congestive heart failure (OR 1.65, 95% CI 1.00-2.73); peptic ulcer disease (OR 3.99, 95% CI 1.18-13.5); diabetes (OR 4.90, 95% CI 1.90-12.6), and the number of complications of care. CONCLUSIONS: Complications of care were common following open elective AAA repair. The complications with the highest mortality included MI, GI bleeding, and respiratory failure. FTR was associated with female sex, comorbidities, and increasing numbers of complications of care. Often, the lowest occurring complications had the highest FTR. Adopting gender-specific assessment tools, a protocol-driven approach for perioperative GI prophylaxis, and preoperative MI risk mitigation may lead to reduced FTR.

Vascular surgery patients have a high incidence of unplanned hospital readmissions and complications. Previous research has not fully examined specific elements of the hospital discharge process for vascular surgery patients to identify issues that may contribute to readmissions. The objective of this qualitative descriptive study was to explore challenges identified by healthcare providers and patients regarding the discharge process from an academic vascular surgery service. Data were collected from eight focus group interviews and analyzed for relevant themes. Patients and healthcare providers identified several challenges within the standard discharge process, including ineffective communication, insufficient time for discharge education, and limitations accessing providers with post-discharge concerns. These obstacles may be ameliorated in part by specialized coordinators, caregiver support, and use of adaptive strategies outside of the current discharge process. The discharge challenges described by study participants likely contribute to adverse post-hospitalization outcomes, including unplanned hospital readmissions. A multifaceted approach that incorporates standardized discharge processes, as well as informal problem-solving strategies, is recommended to improve hospital discharge and outcomes for vascular surgery patients.

OBJECTIVE: Elective abdominal aortic aneurysm (AAA) repair for patients with a diagnosis of cancer has remained controversial. In the present study, we evaluated the in-hospital outcomes for patients who had undergone AAA repair in the setting of a cancer diagnosis. METHODS: Inpatients (2008-2018) who had undergone elective AAA repair were selected from the Cerner Health Facts database using International Classification of Diseases, ninth and tenth revision, procedure codes. We used χ2 analysis and logistic regression models to evaluate the association of patient characteristics with the medical and vascular outcomes. RESULTS: A total of 8663 patients who had undergone AAA repair were identified (270 with a cancer diagnosis and 8393 without a cancer diagnosis). No significant demographic differences were found between the two groups, except that more patients with a cancer diagnosis had undergone endovascular aneurysm repair (EVAR) than open aneurysm repair (88.2% vs 82.1%; P = .01). Male reproductive organ (24.8%) and lung (24.4%) cancer were the most common cancer diagnoses in the cohort. The unadjusted analysis revealed that patients with a cancer diagnosis were more likely to require remedial EVAR (relative risk, 3.47; 95% confidence interval [CI], 1.18-10.2) or reoperation for bleeding, infection, or thrombosis (relative risk, 1.59; 95% CI, 1.09-2.32). Multivariable analysis demonstrated that, overall, patients with a cancer diagnosis were more likely to require a prolonged length of stay (odds ratio [OR], 2.2; 95% CI, 1.5-3.3) and to have developed respiratory failure (OR, 2.1; 95% CI, 1.3-3.4) or infection (OR, 1.7; 95% CI, 1.2-2.4). Similar point estimates were found for men with and without a cancer diagnosis. However, women with a cancer diagnosis had a greater odds of a prolonged length of stay compared with women without a cancer diagnosis (OR, 2.6; 95% CI, 1.2-5.6). EVAR in the presence of a cancer diagnosis was also significantly associated with poor outcomes. CONCLUSIONS: Elective AAA repair for patients with a cancer diagnosis was associated with a prolonged length of stay and the development of infection, respiratory failure, and vascular-specific complications during the inpatient hospitalization. Given that differences in outcomes stratified by gender and treatment modality have been shown for patients with a cancer diagnosis, careful patient selection is important and reinforces the finding that cancer exerts negative systemic postoperative effects even when treated or quiescent.

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) has emerged as a minimally invasive alternative for repairing complex abdominal aortic aneurysms (AAA). Comparisons of outcomes for FEVAR and traditional endovascular aneurysm repair (EVAR) are limited. We evaluated outcomes following elective endovascular AAA repair with FEVAR or EVAR. METHODS: Hospitalizations for elective nonruptured AAA repair from 2014 to 2016 were selected from the Nationwide Readmissions Database (NRD) using ICD-9 and ICD-10 procedure and diagnosis codes. In-hospital mortality, length of stay (LOS), complications, 30-day readmission, and charges were evaluated. Multivariable logistic regression was used to control for confounding between groups. RESULTS: We identified 23,262 EVAR and 2,373 FEVAR with nonruptured elective procedures. In-hospital mortality was 0.14% for both groups (P = 0.99). Of those at risk for readmission (21,152 EVAR, 1,915 FEVAR), index LOS was greater for FEVAR compared to EVAR, 1.8 days versus 1.7 days (P = 0.028). There was no difference in procedure type based on hospital location (P = 0.37), teaching status (P = 0.17) or hospital size (P = 0.26). During the index hospitalization, pneumonia, renal, and respiratory complications were similar between groups (all P > 0.05). FEVAR patients were more likely to experience cardiac complications (P = 0.0098) or hemorrhage (P = 0.029). Total charges for the index stay were greater for FEVAR compared to EVAR ($125,381 vs. $113,513, P < 0.0001). All-cause 30-day readmission was similar between groups (7.0% EVAR vs. 8.0% FEVAR, P = 0.37), as were time to readmission (11.9 vs. 13.3 days, P = 0.16) and readmission charges ($53,967 vs. $56,617, P = 0.75). Renal failure was the most common readmission stay complication, with similar rates for EVAR and FEVAR patients (P = 0.22). Pneumonia was a more common complication during the readmission stay for EVAR patients (P = 0.004). Renal disease and chronic pulmonary disease were the most common comorbidities in the readmission stay for both groups. CONCLUSIONS: For patients with nonruptured elective AAA, FEVAR was not associated with increased mortality, length of stay, readmission, or most complications compared to traditional EVAR. Despite the increased technical complexity of cannulating and stenting visceral arteries with FEVAR, these data demonstrate that FEVAR carries a similar risk of renal, respiratory, and infectious complications compared to traditional EVAR. FEVAR patients were more likely to experience hemorrhagic and cardiac complications during the index hospitalization. EVAR patients were more likely to have pneumonia during readmission. The overall risk for readmission after an endovascular aortic repair was associated with female sex, greater age, chronic pulmonary disease, malignancy, and loss of function. Further investigations into the causes and prevention of 30-day readmissions are needed for both procedures.

BACKGROUND: Limited data exist evaluating preoperative hemoglobin A1c (HbA1c) in patients undergoing vascular procedures for peripheral arterial disease (PAD). This study evaluated the relationship of preoperative HbA1c on outcomes after open and endovascular lower extremity (LE) vascular procedures for PAD. METHODS: We selected patients with PAD admitted for elective LE procedures between September 2008 and December 2015 from the Cerner Health Facts® database using International Classification of Disease, Ninth Edition, Clinical Modification diagnosis and procedure codes. Bivariable analysis and multivariable logistic models examined the association of patient characteristics, procedure type, and preoperative HbA1c (normal < 6.5%, high ≥ 6.5%) with postsurgical outcomes that included infection, renal failure, respiratory or cardiac complications, length of stay, in-hospital mortality, and readmission. RESULTS: Of 4087 patients who underwent a LE vascular procedure for PAD, 2462 (60.2%) had a preoperative HbA1c recorded. The cohort was mostly male (60%), white (73%), and underwent endovascular intervention (77%). Patients with high HbA1c levels were more likely of black race (P < 0.02) and had significantly higher comorbidities (P < 0.0001). Elevated HbA1c was associated with diabetes (P < 0.0001) and cellulitis (P = 0.05) on unadjusted analysis. Multivariable logistic regression (adjusting for patient, hospital, comorbidity and procedural characteristics) revealed that elevated HbA1c was significantly associated with 30-day readmission (OR = 1.06, 95% confidence interval = 1.00-1.12), but was not associated with the other outcomes. An independent diagnosis of diabetes was not predictive of complications or readmission. CONCLUSIONS: Historic glucose control, as evidenced by a high preoperative HbA1c level, is not associated with adverse outcome, other than readmission, in patients undergoing LE procedures for PAD. Given the known association of high perioperative glucose levels with poor outcome following vascular procedures, this is suggestive of a more important effect of perioperative, as opposed to chronic, glucose control upon outcome. Thus, we suggest focusing efforts on creating standardized goal-directed guidelines for glucose control in the perioperative period for LE vascular procedures to potentially mitigate complications.

OBJECTIVE: Transition from the hospital to an outpatient setting is a multifaceted process requiring coordination among a variety of services and providers to ensure a high-quality discharge. Vascular surgery patients comprise a complex population that experiences high unplanned readmission rates. We performed a qualitative study to identify themes for process improvement for vascular surgery patients. A validated discharge process, RED (Re-Engineered Discharge), was used to identify additional actionable themes to create a more efficient discharge process tailored specifically to the vascular surgery population. METHODS: A prospective, qualitative analysis at a tertiary center using a semi-structured focus group interview guide was performed to evaluate the current discharge process and identify opportunities for improvement. Focus groups were Zoom recorded, transcribed into electronic text files, and were loaded into Dedoose qualitative software for analysis using a directed content analysis approach. Two researchers independently thematically coded each transcript, starting with accepted discharge components to identify new thematic categories. Prior to analysis, all redundancy of codes was resolved, and all team members agreed on text categorization and coding. RESULTS: Eight focus groups with a total of 38 participants were conducted. Participants included physicians (n = 13), nursing/ancillary staff (n = 14), advanced nurse practitioners (n = 2), social worker/dietitian/pharmacist (n = 3), and patients (n = 6). Transcript analyses revealed facilitators and barriers to the discharge process. In addition to traditional RED components, unique concepts pertinent to vascular surgery patients included patient complexity, social determinants of health, technology literacy, complexity of ancillary services, discharge appropriateness, and use of advanced nurse practitioners for continuity. CONCLUSIONS: Specific themes were identified to target and enhance the future vRED (vascular Re-Engineered Discharge) bundle. Thematic targets for improvement include increased planning, organization, and communication prior to discharge to address vascular surgery patients' multiple comorbidities, extensive medication lists, and need for complex ancillary services at the time of discharge. Other thematic barriers discovered to improve include provider awareness of patient health literacy, patient understanding of complex discharge instructions, patient technology barriers, and intrinsic social determinants of health in this population. To address these discovered barriers, organizational targets to improve include enhanced social support, the use of advanced nurse practitioners for education reinforcement, and increased coordination. These results provide a framework for future quality improvement targeting the vascular surgery discharge process.
RESUMEN
Facebook® is a popular platform for older adults, especially as they try to stay in contact with their family around the country. It is also a popular platform for hosting online support groups. The readily available, socially acceptable, and free platform holds many advantages not only for older adults but also for nurse researchers designing and implementing interventions for older adults. The literature is void of proven methods to measure individual engagement with the Facebook platform. The current article describes efforts to develop a measurement process and evaluate the impact that engagement with Facebook has on improved mental health outcomes for older adults. Scores were severely skewed and ranged from no engagement to very high engagement. Engagement differed based on sex, race, and living arrangements with patients. Further work in this area is needed if nurse researchers are to consider the role of engagement in social media interventions. [Journal of Gerontological Nursing, 48(7), 10-17.].

OBJECTIVE: A low albumin level has been associated with poor outcome, including death, in surgical patients. The mechanistic relationship, however, is more complex than simply nutritional. As studies are scant in the vascular population, we sought to examine the association of low albumin level with outcomes in patients undergoing open and endovascular lower extremity procedures for peripheral artery disease. METHODS: Patients with peripheral artery disease undergoing lower extremity procedures (2008-2015) were selected from Cerner Health Facts database (Cerner Corporation, Kansas City, Mo) using International Classification of Diseases, Ninth Revision diagnosis and procedure codes. Age, sex, disease severity, and other comorbidities were captured. Outcomes were identified using codes and encounter data. A χ2analysis and multivariable logistic regression were performed. RESULTS: There were 6170 patients evaluated; 4562 (74%) underwent endovascular procedures and 1608 (26%) underwent open surgery. Low albumin level (<3.5 g/dL) was associated with age ≥80 years (23.1% vs 16.3% normal; P < .0001), black race (21% vs 11.6% normal; P < .0001), tissue loss (38% vs 16.4% normal; P < .0001), and higher Charlson index (mean, 3.1 vs 2.2 in the normal group; P < .0001). Low albumin level was also associated with longer length of stay (4.9 vs 2.2 days normal; P < .0001), higher in-hospital mortality (1.9% vs 0.3% normal; P < .0001), and higher 30-day readmission (15% vs 12.7% normal; P = .02). Multivariable analysis demonstrated that low albumin level was strongly associated with in-hospital death (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.00-13.70), infection (OR, 2.51; 95% CI, 1.96-3.22), renal failure (OR, 2.61; 95% CI, 1.79-3.79), and cardiac complications (OR, 2.59; 95% CI, 1.69-3.96). After multivariable adjustment, there was no association between albumin level and 30-day readmission. CONCLUSIONS: Low preoperative albumin levels are associated with in-hospital death, prolonged length of stay, and severe morbidity after open and endovascular lower extremity procedures. As the majority of lower extremity procedures are elective, serious consideration should be given to deferring elective procedures until albumin levels have been optimized. Because of the pleiotropic effects of albumin, including antiplatelet and inflammatory function, study of this complex relationship may offer insights into how best to integrate this novel biomarker into vascular surgery decision-making.

OBJECTIVE: The current study evaluated all-cause 30-day readmissions after carotid endarterectomy. METHODS: Patients undergoing carotid endarterectomy were selected from the Cerner Health Facts® database using ICD-9-CM procedure codes from their index admission. Readmission within 30 days of discharge was determined. Chi-square analysis determined characteristics of the index admission (demographics, diagnoses, postoperative medications, and laboratory results) associated with readmission. Multivariate logistic regression models were used to identify characteristics independently associated with readmission. RESULTS: In total, 5257 patients undergoing elective carotid endarterectomy were identified. Readmission within 30 days was 3.1%. After multivariable adjustment, readmission was associated with end-stage renal disease (OR: 3.21, 95% CI: 1.01-10.2), hemorrhage or hematoma (OR: 2.34, 95% CI: 1.15-4.77), procedural complications (OR: 3.07, 95% CI: 1.24-7.57), use of bronchodilators (OR: 1.48, 95% CI: 1.03-2.11), increased Charlson index scores (OR: 1.22, 95% CI: 1.08-1.38), and electrolyte abnormalities (hyponatremia < 135 mEq/L (OR: 1.69, 95% CI: 1.07-2.67) and hypokalemia less than 3.7 mEq/L (OR: 2.26, 95% CI: 1.03-4.98)). CONCLUSIONS: Factors associated with readmission following carotid endarterectomy included younger age, increased comorbidity burden, end-stage renal disease, electrolyte disorders, the use of bronchodilators, and complications including bleeding (hemorrhage or hematoma). Of note, in this real-world study, only 40% of the patients received protamine, despite evidence-based literature demonstrating the reduced risk of bleeding complications. As healthcare moves towards quality of care-driven reimbursement, physician modifiable targets such as protamine utilization to reduce bleeding are greatly needed to reduce readmission, and failure to reduce preventable physician-driven complications after carotid interventions may be associated with decreased reimbursement.

OBJECTIVE: Neutrophil-lymphocyte ratio (NLR) has been associated with inferior outcomes after lower extremity interventions. NLR has been associated with systemic inflammation and atherosclerotic burden. We examined NLR, severity of peripheral artery disease (PAD), and outcomes after endovascular or open surgical procedures. METHODS: Inpatients undergoing lower extremity procedures (2008-2016) were selected from Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo) using International Classification of Diseases, Ninth Revision procedure codes. Disease severity was grouped into claudication, rest pain, and tissue loss. Outcomes were identified using International Classification of Diseases, Ninth Revision codes. NLR was calculated preoperatively and postoperatively. A χ2 analysis and multivariable logistic regression were performed. A receiver operating characteristic curve analysis was used to determine the cutoff for preoperative (low, <3.65; high, ≥3.65) and postoperative (low, <5.96; high, ≥5.96) NLR values. RESULTS: There were 3687 patients evaluated; 2183 (59%) underwent endovascular procedures and 1504 (41%) had open procedures. Compared with black patients, claudication was more frequent in white patients (81.7% vs 72.7%; P < .0001), and tissue loss was less common (12.9% vs 20.9%; P < .0001). NLR values were higher for patients with tissue loss than for patients with rest pain or claudication (4.89, 4.33, and 3.11, respectively; P < .0001). Open procedures were associated with higher postoperative NLR values than endovascular procedures (6.8 vs 5.2; P < .0001). Mean preoperative and postoperative NLR values were greater in patients with more severe PAD. Multivariable analysis demonstrated that preoperative high NLR was strongly associated with in-hospital death (odds ratio [OR], 5.4; 95% confidence interval [CI], 1.68-17.07), cardiac complications (OR, 2.9; 95% CI, 1.57-5.40), amputation (OR, 2.5; 95% CI, 1.65-3.87), renal failure (OR, 1.9; 95% CI, 1.18-2.93), respiratory complications (OR, 1.7; 95% CI, 1.09-2.76), and prolonged length of stay (OR, 1.9; 95% CI, 1.89-3.71). CONCLUSIONS: Preoperative and postoperative NLR significantly increases with disease severity for PAD, providing further evidence of NLR as a biomarker of a patient's systemic inflammatory state. After adjustment for confounders, NLR still remained strongly associated with death and other adverse outcomes after intervention for PAD. Further study of the clinical association of NLR with other vascular disorders, such as symptomatic carotid stenosis and symptomatic and ruptured aortic aneurysmal disease, is planned to guide individualized treatment to prevent stroke or aneurysm rupture.

OBJECTIVE: Peripheral artery disease (PAD) has been shown to affect health status and quality of life; however, the disability associated by specific anatomic level of disease is unknown. We evaluated patients presenting with claudication by anatomic level and used the Peripheral Artery Questionnaire (PAQ), a PAD-specific validated tool, to quantify patients' symptoms, function, treatment satisfaction, and quality of life. METHODS: The Patient-centered Outcomes Related to Treatment Practices in peripheral Arterial disease: Investigating Trajectories (PORTRAIT) registry is a multicenter, international, prospective study of patients with PAD. Anatomic level of PAD was stratified as follows: aortoiliac only, femoral-popliteal only, infrapopliteal only, and multilevel disease. Health status information was collected at baseline and at 3, 6, and 12 months using the PAQ. Student t-test, χ2 test, and linear mixed effects models were examined. RESULTS: Anatomic data were present in 623 (48.9%) of 1275 patients: 127 aortoiliac (20.4%), 221 femoral-popliteal (35.5%), 39 infrapopliteal (6.3%), and 236 multilevel disease (37.9%). Groups were similar by sex and race. Baseline PAQ summary scores differed between lesions, with multilevel disease having the lowest (poorest) estimated PAQ summary score (P = .014). Patients with aortoiliac disease were significantly younger, were more likely to be smokers, and presented with higher ankle-brachial index (all P < .05). Almost one-fourth of patients underwent an intervention by 3 months, 83% of which were endovascular. Repeated-measures analyses demonstrated a significant association between anatomic lesion and PAQ scores over time (P = .016), even after adjustment for age, sex, work status, ankle-brachial index, smoking, history of diabetes and chronic kidney disease, and country. Multilevel disease had the lowest adjusted average PAQ summary score over time (63.1; 95% confidence interval [CI], 60.8-65.5) and was significantly lower than aortoiliac (68.1; 95% CI, 64.8-71.4; P = .02) and femoral-popliteal (68.2; 95% CI, 65.8-70.6; P = .002) but not infrapopliteal (66.2; 95% CI, 60.5-72.0; P = .32). CONCLUSIONS: Overall, patients with claudication had similar health status on presentation by level of disease, yet patients with isolated aortoiliac disease fared significantly better over time with regard to quality of life and PAQ scores. Subset analysis demonstrated that patients undergoing interventions for aortoiliac disease and multilevel disease, which were primarily endovascular procedures, appeared to improve health status more over time compared with femoral-popliteal and infrapopliteal interventions. No significant benefits were found with intervention for femoral-popliteal disease or infrapopliteal disease compared with medical management. Treatment of aortoiliac and multilevel disease for claudication should be considered by clinicians as it may represent the greatest potential benefit for improving overall health status in patients with PAD. Further studies evaluating intervention compared with medical management alone are needed to further evaluate this finding.

OBJECTIVE: We evaluated the association between postoperative hyperglycemia and outcomes after abdominal aortic aneurysm (AAA) repair. METHODS: We used diagnosis and procedure codes (International Classification of Diseases, Ninth Revision, Clinical Modification) to identify patients who underwent open or endovascular repair of a nonruptured AAA from September 2008 to March 2014 from the Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo). We evaluated the association between postoperative hyperglycemia (glucose concentration >180 mg/dL) and infections, in-hospital mortality, readmission, patients' characteristics, length of hospital stay, and medications. Multivariable logistic models examined the association of postoperative hyperglycemia with in-hospital infection and mortality. RESULTS: Of 2478 patients, 2071 (83.5%) had good postoperative glucose control (80-180 mg/dL), and 407 (16.5%) had suboptimal control (hyperglycemia). Patients who had postoperative hyperglycemia experienced longer hospital stays (9.5 vs 4.7 days; P < .0001), higher infection rates (18% vs 8%; P < .0001), higher in-hospital mortality (8.4 vs 1.2%; P <.0001), and more acute complications (ie, acute renal failure, fluid and electrolyte disorders, respiratory complications). After adjusting for patients' characteristics and medications, multivariable logistic regression models demonstrated that patients receiving postoperative insulin had nearly 1.6 times the odds of having an infectious complication (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.12-2.2; P = .007) than those who did not. Hyperglycemic patients had 3.5 times the odds of in-hospital mortality (OR, 3.48; 95% CI, 1.78-6.80 [P = .0003]; 2.3% vs 1.2%; P < .001). When stratified by procedure type, patients with hyperglycemia who underwent endovascular repair had nearly 2 times the odds of an infectious complication (OR, 1.85; 95% CI, 0.98-3.51; P = .05) and 7.5 times the odds of in-hospital mortality (OR, 7.54; 95% CI, 1.95-29.1; P = .003). Patients who underwent an open AAA repair and who had hyperglycemia had three times the odds of dying in the hospital (OR, 3.05; 95% CI, 1.29-7.21; P = .01). CONCLUSIONS: Among patients undergoing elective AAA repair, approximately one in six had postoperative hyperglycemia. After AAA repair in patients with and without diabetes, postoperative hyperglycemia was associated with adverse events, including in-hospital mortality and infections. Compared with those who had open surgery, patients undergoing endovascular repair who had postoperative hyperglycemia had greater risk of infection and death. After controlling for insulin administration and postoperative hyperglycemia, a diabetes diagnosis was associated with lower odds of both infection and in-hospital mortality. Our study suggests that hyperglycemia may be used as a clinical marker as it was found to be significantly associated with inferior outcomes after elective AAA repair. This retrospective study, however, cannot imply causation; further study using prospective methods is needed to elucidate the relationship between postoperative hyperglycemia and patient outcomes.

Background: We conducted a retrospective cohort study of thirty-day readmission after abdominal aortic aneurysm (AAA) repair. Patients and methods: Inpatients (2009-2016) undergoing elective AAA repair were selected from the multicenter Cerner Health Facts® database using ICD-9 procedure codes. We identified characteristics associated with 30-day readmission with chi-square analysis and logistic regression. Results: 4,723 patients undergoing elective AAA procedures were identified; 3,101 endovascular aneurysm repairs (EVAR) and 1,622 open procedures. Readmission differed by procedure type (6.5 % EVAR vs. 9.3 % open, p =.0005). Multivariable logistic regression found that patients undergoing EVAR were less likely to be readmitted (OR 0.71, 95 % CI 0.54-0.92) than patients undergoing open repair. The following risk factors were associated with 30-day readmission following any AAA repair: surgical site infection during the index admission (OR 2.79, 95 % CI 1.25-6.22), age (OR 1.03, 95 % CI 1.01-1.05), receipt of bronchodilators (OR 1.34, 95 % CI 1.06-1.70) or steroids (OR 1.45, 95 % CI 1.04-2.02), serum potassium > 5.2 mEq/L (OR 1.89, 95 % CI 1.16-3.06), and higher Charlson co-morbidity scores (OR 1.12, 95 % CI 1.04-1.21). Subgroup analysis revealed that age (OR 1.02, 95 % CI 1.01-1.04), higher Charlson comorbidity scores (OR 1.20, 95 % CI 1.09-1.33), and receipt of post-operative bronchodilators (OR 1.39, 95 % CI 1.03-1.88) were risk factors for 30-day readmission following EVAR. After open procedures, readmission was associated with surgical site infection during the index admission (OR 2.91, 95 % CI 1.17-7.28), chronic heart failure (OR 2.18, 95 % CI 1.22-3.89), and receipt of post-operative steroids (OR 1.92, 95 % CI 1.24-2.96). The most common infections were pneumonia after open procedures and urinary tract infection after EVAR. Conclusions: The risk factor most associated with 30-day readmission after elective AAA repair was surgical site infection. Awareness of these risk factors and vulnerable groups may help identify high-risk patients who could benefit from increased surveillance programs to reduce readmission.

Background This study evaluated risk factors associated with 30-day readmission after open and endovascular lower extremity revascularization. Methods Patients admitted with peripheral artery disease and lower extremity procedures were selected from national electronic medical record data, Cerner Health Facts® (2008-2014). Thirty-day readmission was determined. Logistic regression models identified characteristics independently associated with readmission. Results There were 2781 open and 2611 endovascular procedures. Readmission was 10.9% (9.6% open versus 12.3% endovascular, p<.0001). Greater disease severity was associated with readmission for both groups. Readmission factors for lower extremity bypass: blood transfusions (OR 2.25, 95% CI 1.62-3.13), hyponatremia (OR 1.72, 95% CI 1.15-2.57), heart failure (OR 1.57, 95% CI 1.07-2.29), bronchodilators (OR 1.50, 95% CI 1.13-2.00), black race (OR 1.43, 95% CI 1.03-1.99), and hypokalemia (OR 0.43, 95% CI 0.20-0.95). Readmission factors for endovascular procedures: vasodilators (OR 1.63, 95% CI 1.22-2.16), end-stage renal disease (OR 1.43, 95% CI 1.02-2.01), fluid and electrolyte disorders (OR 1.44, 95% CI 1.00-2.06), hypertension (OR 1.33, 95% CI 0.99-1.76), coronary artery disease (OR 1.31, 95% CI 1.02-1.67), and diuretics (OR 1.30, 95% CI 1.01-1.70). Conclusions Readmission after lower extremity revascularization is associated with disease severity for both procedures. Factors associated with readmission following lower extremity bypass included heart failure, transfusions, hyponatremia, black race, and bronchodilator use. Risk factors for endovascular readmissions were often chronic conditions including coronary artery disease, kidney disease, hypertension, and hypertensive medications. Awareness of risk factors may help providers identify high-risk patients who may benefit from increased surveillance and programs to lower readmission.

OBJECTIVE: The effect of postoperative hyperglycemia in patients undergoing open and endovascular procedures on the lower extremities has not been fully characterized with regard to associated admission diagnoses, hospital complications, mortality, and 30-day readmission. This study evaluated the relationship of postoperative hyperglycemia on outcomes after lower extremity vascular procedures for peripheral artery disease. METHODS: Patients with peripheral artery disease admitted for elective lower extremity procedures between September 2008 and March 2014 were selected from the Cerner Health Facts (Cerner Corporation, Kansas City, Mo) database using International Classification of Diseases, Ninth Edition, Clinical Modification diagnosis and procedure codes. Using χ2 analysis, we evaluated the relationship of postoperative hyperglycemia (>180 mg/dL) with sociodemographic characteristics, acute and chronic diagnoses, infections, hospital length of stay (LOS), and 30-day readmission. An adjusted multivariable logistic model was used to examine the association of postoperative hyperglycemia with infection and LOS. RESULTS: Of 3586 patients in the study, 2812 (78%) had optimal postoperative glucose control, and 774 (22%) had suboptimal glucose control (hyperglycemia). On average, patients with postoperative hyperglycemia experienced longer hospital stays (6.9 vs 5.1 days; P < .0001), higher Charlson Comorbidity Index scores (3.4 vs 2.5, P < .0001), higher rates of infection (23% vs 14%, P < .0001), more acute complications (ie, fluid and electrolyte disorders, acute renal failure, postoperative respiratory complications), and chronic problems (ie, anemia, chronic heart disease, chronic kidney disease, and diabetes) than patients with optimal glucose control. Overall 30-day readmission was 10.9% and was similar between the groups (10.9% for both; P = .93). Major amputations did not differ between groups (P = .21). After adjusting for other risk factors using multivariable logistic regression, patients with hyperglycemia have 1.3-times the odds to have an infectious complication compared with those with optimal glucose control (odds ratio [OR], 1.34; 95% confidence interval [CI], 1.06-1.69) and 1.7-times the odds to have a hospital LOS >10 days (OR, 1.69; 95% CI, 1.32-2.15). As well, patients with postoperative hyperglycemia have 8.4-times the odds of dying in the hospital (OR, 8.40; 95% CI, 3.95-17.9). CONCLUSIONS: One in five patients undergoing vascular procedures had postoperative hyperglycemia. Postoperative hyperglycemia was associated with adverse events after lower extremity vascular procedures in patients with and without diabetes, including infection, increased hospital utilization, and mortality. No difference was found with respect to hospital readmission. Postprocedure glucose management may represent an important quality marker for improving outcomes after lower extremity vascular procedures.

INTRODUCTION: Family caregivers are socially isolated and burdened as they care for their loved one, often for many years. Internet support groups can address some of the barriers related to the social isolation, self-efficacy, and burden experienced during caregiving by connecting individuals with similar problems to one another. The purpose of the meta-analysis was to analyze the effect of Internet-based group support interventions on social support, self-efficacy, and burden. METHODS: A two-step search process was used to identify peer reviewed evidence to answer the research question. Multiple databases, including MEDLINE, Cochrane Database of Systematic Reviews, CINAHL, PsycINFO, and several others, were searched to identify systematic reviews from which to identify the final articles for data extraction. RESULTS: Seven systematic reviews identified 10 studies to answer the research question. A statistically significant effect was found from the interventions targeting social support and self-efficacy. We were unable to assess the effect of these interventions on caregiver burden due to the variance in measurement constructs. CONCLUSIONS: While it has been found that Internet group support interventions have a positive effect on social support and self-efficacy, the size and quality of studies are moderate, and thus, large-scale randomized controlled trials are needed for a higher level of evidence.

OBJECTIVE: Cilostazol, an antiplatelet agent with vasodilating properties, has not been well evaluated in conjunction lower extremity revascularization (LER). We evaluated the association between cilostazol and limb salvage after endovascular or open surgery for LER. METHODS: Patients aged ≥65 years undergoing LER were identified from 2007 to 2008 Medicare Provider Analysis and Review and Carrier files using International Classification of Diseases-9 Edition-Clinical Modification and Current Procedural Terminology-4 codes. Covariates included demographics, comorbidities, and disease severity. Use of cilostazol was identified using National Drug Codes and Part D files. Outcomes were compared using χ(2) and Kaplan-Meier analyses and Cox regression. RESULTS: We identified 22,954 patients undergoing LER: 8128 (35.4%) with claudication, 3056 (13.3%) with rest pain, and 11,770 (51.3%) with ulceration/gangrene. Among them, 1999 patients (8.7%) used cilostazol before LER. More patients received endovascular (14,353) than open (8601) procedures. Cilostazol users had fewer amputations than nonusers at 30 days (7.8% vs 13.4%), 90 days (10.7% vs 18.0%), and 1 year (14.8% vs 24.0%; P < .0001 for all). Cox proportional hazards regression with adjustment for age, gender, race, comorbidities, type of procedure, and atherosclerosis severity showed noncilostazol users were more likely to undergo amputation ≤1 year after surgery (hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.02-1.29; P = .02). Subgroup analyses using Cox proportional hazards models adjusted for age, gender, and comorbidities demonstrated significantly improved 1-year amputation-free survival for patients with renal failure (HR, 1.61; 95% CI, 1.28-2.02; P < .001) and diabetes (HR, 1.61; 95% CI, 1.36-1.92; P < .001) who were taking cilostazol. CONCLUSIONS: In patients undergoing LER, cilostazol use was associated with improved 1-year freedom from amputation. Patients with renal failure and diabetes also demonstrated a significant benefit from taking cilostazol. Further studies are needed to evaluate the benefits of cilostazol after LER.

OBJECTIVE: Assess the association between caregiver supervision and acute unintentional injury in young children; evaluate whether lower levels of supervision result in more severe injury. METHODS: A case cross-over study was conducted. Parents of children aged ≤4 years whose injuries required emergency department (ED sample) treatment or admission to the hospital (inpatient sample) were interviewed. Information on supervision (3 dimensions: proximity, attention, continuity) at the time of injury and 1â h before the injury (control time) was collected. An overall supervision score was created; a higher score indicates closer supervision. Hospital admission served as a proxy for injury severity. ORs and 95% CIs were calculated. RESULTS: Interviews were completed by 222 participants; 50 (23%) were in the inpatient sample. For each supervision dimension the inpatient sample had higher odds of injury, indicating effect modification requiring separate analyses for inpatient and ED samples. For both samples, proximity 'beyond reach' was associated with the highest odds of injury; compared with 1â h before injury, children were more likely to be beyond reach of their caregiver at the time of injury (inpatient sample: OR 11.5, 95% CI 2.7 to 48.8; ED sample: OR 2.9, 95% CI 1.8 to 4.9). Children with lower supervision scores had the greatest odds of injury (inpatient sample: OR 8.0, 95% CI 2.4 to 26.6; ED sample: OR 3.3, 95% CI 1.9 to 5.6). CONCLUSIONS: Lower levels of adult supervision are associated with higher odds of more severe injury in young children. Proximity is the most important supervision dimension for reducing injury risk.
