RESUMEN
With this paper, we walk out some central ideas about posthumanisms and the ways in which nursing is already deeply entangled with them. At the same time, we point to ways in which nursing might benefit from further entanglement with other ideas emerging from posthumanisms. We first offer up a brief history of posthumanisms, following multiple roots to several points of formation. We then turn to key flavors of posthuman thought to differentiate between them and clarify our collective understanding and use of the terms. This includes considerations of the threads of transhumanism, critical posthumanism, feminist new materialism, and the speculative, affirmative ethics that arise from critical posthumanism and feminist new materialism. These ideas are fruitful for nursing, and already in action in many cases, which is the matter we occupy ourselves with in the final third of the paper. We consider the ways nursing is already posthuman-sometimes even critically so-and the speculative worldbuilding of nursing as praxis. We conclude with visions for a critical posthumanist nursing that attends to humans and other/more/nonhumans, situated and material and embodied and connected, in relation.

OBJECTIVES: Opioids are commonly used for pain control after lower extremity amputations (LEA)-below the knee amputations (BKA) and above the knee amputations (AKA). Well-defined benchmarks for prescription requirements after amputation are deficient. This analysis evaluated opioid utilization after amputation to identify high-risk patients and provide recommendations for post-hospitalization opioid prescriptions at discharge. METHODS: Patients undergoing LEA (2008-2016) with identified peripheral vascular disease were selected from Cerner's Health Facts® database using ICD-9 and 10 diagnosis and procedure codes. Patient demographics, disease severity, comorbidities, and hospital characteristics were evaluated. Post-operative opioid medications administered intravenously and orally during the hospital stay were identified from the data and converted to Morphine Milligram Equivalent per day (MME/d) for an evaluation and comparison during the index hospitalization. Descriptive statistics were used to report continuous and dichotomous variables. Dichotomous variables are reported as n (%) and continuous variables are reported as mean ± standard deviation (SD). Chi-square and T-tests were used as appropriate. RESULTS: 2399 patients who underwent AKA or BKA with peripheral vascular disease were evaluated. Sixty-three percent of the cohort was male, 67% Caucasian, and 42% married, and 58% had a Charlson index >3. The majority of patients had an average length of hospital stay of 5.7 days (M = 5.72, SD = 4.56). Patient groups that used significantly higher MME/d in the early postop period included: BKA (29.2 vs 20.7, p = 0.006), males (62.6 vs 54.0, p < 0.0001), Caucasians (64.3 vs 44.7, p < 0.0001), younger patients (69.6 vs 54.0, p < 0.0001), and those at non-training institutions (66.7 vs 56.7, p < 0.0001). Patients whose hospital stay was greater than 6 days were found to have increased opioid utilization likely secondary to index complications. For those discharged by post-operative day 7, the mean MME utilized on postop day 1 was 59.5 and decreased to a mean MME/d utilization prior to discharge of 17.6. CONCLUSIONS: This analysis demonstrates that younger patients, males, patients with BKAs, and those who receive amputations for vascular disease at non-training institutions have higher post-operative opioid utilization during the hospital stay. At the time of discharge, patients utilized an average of 17.6 MME/d which equates to approximately three hydrocodone/acetaminophen 5/325 mg tablets per day. Based on these findings, vascular surgeons are likely over prescribing opioids at discharge and must be cognizant of appropriate dosing quantities. Prescriptions at discharge should reflect the daily utilization described from this analysis and tapered to avoid chronic utilization, overdose, and possible death.

This paper presents an overview of the process of entanglement at the 25th International Philosophy of Nursing Conference (IPNC) at University of California at Irvine held on August 18, 2022. Representing collective work from the US, Canada, UK and Germany, our panel entitled 'What can critical posthuman philosophies do for nursing?' examined critical posthumanism and its operations and potential in nursing. Critical posthumanism offers an antifascist, feminist, material, affective, and ecologically entangled approach to nursing and healthcare. Rather than focusing on the arguments of each of the three distinct but interrelated panel presentation pieces, this paper instead focuses on process and performance (per/formance) and performativity as relational, connected and situated, with connections to nursing philosophy. Building upon critical feminist and new materialist philosophies, we describe intra-activity and performativity as ways to dehierarchise knowledge making practices within traditional academic conference spaces. Creating critical cartographies of thinking and being are actions of possibility for building more just and equitable futures for nursing, nurses, and those they accompany-including all humans, nonhumans, and more than human matter.
RESUMEN
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: Endovascular aneurysm repair is the standard of care for abdominal aortic aneurysm repair, however data regarding adjunctive stenting at the time of endovascular aneurysm repair (EVAR) are limited. The study aims to evaluate outcomes of patients undergoing EVAR with and without adjunctive stenting. METHODS: Patients undergoing EVAR with stenting (EVAR-S) and without stenting (EVAR) (2008 - 2017) were selected from Cerner HealthFacts database using ICD-9 diagnosis and procedure codes. Chi-square analysis and multivariable logistic regression were used to evaluate the association of patient characteristics with medical and vascular outcomes. RESULTS: 4,957 patients undergoing EVAR procedures were identified (3,816 EVAR and 1,141 EVAR-S). Demographic analysis revealed that patients who underwent EVAR-S had higher Charlson comorbidity scores (2.35 vs. 2.13, P = 0.0001). EVAR-S was associated with a greater frequency of vascular complications such as thrombolysis/percutaneous thrombectomy (0.9% vs. 0.2%; P < 0.0004). There were no differences seen in access complications between EVAR and EVAR-S. Multivariable analysis revealed that EVAR-S was associated with prolonged length of stay (OR 1.37, 95% CI 1.03-1.82), readmission < 30 days (OR 1.36, 95% CI 1.11-1.68), major adverse cardiac events (OR 1.59, 95% CI 1.09-2.32), respiratory complications (OR 1.47, 95% CI 1.16-1.88) and renal failure (OR 1.57, 95% CI 1.16-2.11). CONCLUSION: Endovascular aneurysm repair with adjunctive stenting (EVAR-S) was associated with vascular complications requiring reintervention, although the overall rate was very low. As well, readmission within 30 days, cardiac complications, respiratory problems and renal failure were more likely when compared to standard EVAR. The need for adjunctive stenting acts as a marker for an overall sicker and more complex population, not just in terms of vascular complications but across all medical complications as well. Staging the procedure may be helpful in terms of spreading out the operative risk into smaller portions. Furthermore, consideration of a non-operative strategy should be discussed with the patient if the risk of the procedure outweighs the risk of aneurysm rupture in high-risk groups.

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.

Research has demonstrated a lack of support for hospice caregivers and a higher than average level of self-reported anxiety and depression. While online support groups are gaining popularity, few protocols have been published, little research has demonstrated the skills required to facilitate, and virtually no data has explored the clinical outcomes affiliated with participation in such groups. This paper presents the preliminary experience and results of a clinical trial testing the use of online support groups designed to both educate and provide social support to caregivers of hospice cancer patients. A detailed protocol outlines educational strategies, discussion questions, and a blueprint outlining ways to engage participants. A review of field notes completed by the interventionist reveal specific facilitation skills and strategies used to engage participants. Finally, preliminary analysis of 78 participants shows the group is having a statistically significant impact on the caregiver depression.

Despite the prominence of person-centred care (PCC) in nursing, there is no general agreement on the assumptions and the meaning of PCC. We sympathize with the work of others who rethink PCC towards relational, embedded, and temporal selfhood rather than individual personhood. Our perspective addresses criticism of humanist assumptions in PCC using critical posthumanism as a diffraction from dominant values We highlight the problematic realities that might be produced in healthcare, leading to some people being more likely to be disenfranchised from healthcare than others. We point to the colonial, homo- and transphobic, racist, ableist, and ageist consequences of humanist traditions that have influenced the development of PCC. We describe the deep rooted conditions that structurally uphold inequality and undermine nursing practice that PCC reproduces. We advocate for the self-determination of patients and emphasize that we support the fundamental mechanisms of PCC enabling patients' choice; however, without critical introspection, these are limited to a portion of humans. Last, we present limitations of our perspective based on our white*-cisheteropatriarchy** positionality. We point to the fact that any reimagining of models such as PCC should be carefully done by listening, following, and ceding power to people with diversity dimensions*** and the lived experience or expertise that exists from diverse perspectives. We point towards Black, queer feminism, and critical disabilities studies to contextualize our point of critique with humanism and PCC to amplify equity for all people and communities. Theory and philosophy are useful to understand restrictive factors in healthcare delivery and to inform systematic strategies to improve the quality of care so as not to perpetuate the oppression of groups of people with diversity dimensions. * We purposely capitalize Black and use lower case for white to decentre whiteness and as an intentional act of antiracism (see White Homework a podcast series by Tori W. Douglas). ** Cisheteropatriarchy describes people with intersecting identities of dominant social groups; cisgender is the gender identity that aligns with the gender you were assigned at birth, hetero means heterosexual, and patriarchy refers to structural systems of power based on maleness where women are often excluded and hold less power. *** With diversity dimensions, we refer to subjective lived experience and material realities of people that exist outside the 'dominant minorities' of white-cisheteropatriarchy, meaning groups of people in society who historically and currently hold more power and through this, structurally dominate the norms and possibilities of living for other people.

Forecasts predict a growing shortage of skilled nursing staff in countries worldwide. Nurse migration is already a common strategy used to address nursing workforce needs. Germany, the UK, and Australia are reviewed here as examples of destination countries for nurse migrants. Agreements exist between countries to facilitate nurse migration; however, it is not evident how nurse migrants have contributed to data on which these arrangements are based. We examined existing primary research on nurse migration, including educational needs and initiatives to support policymakers', stakeholders', and health professions educators' decisions on measures for ethical and sustainable nurse migration. We conducted a rapid evidence assessment to review available empirical research data which involved, was developed with, or considered migrant nurses to address the research question: what are the findings of research that directly involves migrant nurses in producing primary research data? A total of 56 papers were included. Four main themes were identified in this research data: Research does not clearly define what is meant by the term migrant nurses; discrimination is often reported by migrant nurses; language and communication competencies are important; and structured integration programs are highly valued by migrant nurses and destination healthcare employers.Migrant nurses continue to experience discrimination and reduced career opportunities and therefore should be included in research about them to better inform policy. Structured integration programs can improve the experience of migrant nurses by providing language support (if necessary), a country-specific bridging program and help with organisational hurdles. Not only researching migrant nurses but making them active partners in research is of great importance for successful, ethical, and sustainable migration policies. A broader evidence base, especially with regard to the views and experiences of migrant nurses and their educational support needs, should be promoted to make future immigration policy more needs-based, sustainable and ethically acceptable.

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: Because the treatment of intermittent claudication (IC) is elective, good short- and long-term outcomes are imperative. The objective of the present study was to examine the outcomes of endovascular management of IC reported in the Vascular Quality Initiative and compare them with the Society for Vascular Surgery guidelines for IC treatment to determine whether real-world results are within the guidelines. METHODS: Patients undergoing peripheral vascular intervention for IC from 2004 to 2017 with complete data and >9 month follow-up were included. The primary outcome measures were IC recurrence and repeat procedures performed ≤2 years after the initial treatment. RESULTS: A total of 16,152 patients met the inclusion criteria, with a mean age of 66 years. Of the 16,152 patients, 61% were men, 45% were current smokers, and 28% had been discharged without antiplatelet or statin medication. Adjusted analyses revealed that treatment of more than two arteries was associated with a shorter time to IC recurrence (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.09-1.31) and a shorter time to repeat procedures (HR, 1.25; 95% CI, 1.09-1.45). The use of atherectomy was also associated with a shorter time to IC recurrence (HR, 1.29; 95% CI, 1.08-1.33) and a shorter time to repeat procedures (HR, 1.31; 95% CI, 1.13-1.52). Discharge with antiplatelet and statin medications was associated with a longer time to IC recurrence (HR, 0.84; 95% CI, 0.78-0.91) and a longer time to repeat procedures (HR, 0.77; 95% CI, 0.69-0.87). Life-table analysis at 2 years revealed that only 32% of patients were free from IC recurrence, although 76% had not undergone repeat procedures. Stratified by anatomic treatment level, 37% of isolated aortoiliac interventions, 22% of aortoiliac and femoropopliteal interventions, 30% of isolated femoropopliteal interventions, and 20% of femoropopliteal and tibial interventions had remained free from IC recurrence at 2 years. CONCLUSIONS: Most patients treated with an endovascular approach to IC did not meet the Society for Vascular Surgery guidelines for long-term freedom from recurrent symptoms of >50% at 2 years. Many lacked preprocedure optimization of medical management. The use of atherectomy and treatment of more than two arteries were associated with poor outcomes after peripheral vascular intervention for IC, because only 32% of these patients were free from recurrent symptoms at 2 years. Even when risk factor modification is optimized before the procedure, vascular specialists should be aware of the association between atherectomy and multivessel interventions with poorer long-term outcomes and counsel patients appropriately before intervention.

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.

PURPOSE: Conventional clinic blood pressure (BP) measurements are routinely used for hypertension management and physician performance measures. We aimed to check home BP measurements after elevated conventional clinic BP measurements for which physicians did not intensify treatment, to differentiate therapeutic inertia from appropriate inaction. METHODS: We conducted a pre and post study of home BP monitoring for patients with uncontrolled hypertension as determined by conventional clinic BP measurements for which physicians did not intensify hypertension management. Physicians were notified of average home BP 2-4 weeks after the initial clinic visit. Outcome measures were the proportion of patients with controlled hypertension using average home BP measurements, changes in hypertension management by physicians, changes in physicians' hypertension metrics, and factors associated with home-clinic BP differences. RESULTS: Of 90 recruited patients who had elevated conventional clinic BP recordings, 65.6% had average home BP measurements that were <140/90 mm Hg. Physicians changed treatment plans for 61% of patients with average home BP readings of ≥140/90 mm Hg, whereas decisions to not change treatment for the remaining patients were based on contextual factors. Substituting average home BP for conventional clinic BP for 4% of patients from 2 physicians' hypertension registries improved the physicians' hypertension control rates by 3% to 5%. Greater body mass index and increased number of BP medications were associated with home BP measurement ≥140/90 mm Hg. Clinic BP levels did not estimate normal home BP levels. CONCLUSIONS: Documented home BP in cases of clinical uncertainty helped differentiate therapeutic inertia from appropriate inaction and improved physicians' hypertension metrics.

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.

Objectives Optical coherence tomography chronic total occlusion catheter, the Ocelot (Avinger Inc., Redwood City, CA), has been utilized to cross Trans-Atlantic Inter-Society Consensus D lesions. This study evaluated the preoperative computerized tomography angiography of chronic total occlusions in the superficial femoral artery to predict clinical success. Methods We reviewed all patients who underwent lower extremity procedures with the Ocelot catheter from June 2014 to August 2016. Patients who had a preoperative computerized tomography angiography were evaluated. Final outcomes, plaque morphology, lesion length, calcium surface area, lesion location, and patient characteristics were analyzed. Results A total of 107 patients underwent lower extremity interventions with the Ocelot catheter. Seventy patients had a preoperative computerized tomography angiography scan prior to lower extremity intervention and 77% (54) had Trans-Atlantic Inter-Society Consensus D lesions that were crossed. Mean age was 62.8 years and 68.6% were male. Mean chronic total occlusion length was 182.7 mm (170.8 mm crossed vs. 222.6 mm uncrossed, p = 0.03). Calcium distribution differed significantly ( p<.01): circumferential (14.8 vs. 12.5%); eccentric (85 vs. 62.5%); and complete calcium occlusion (0 vs. 25%) for lesions that were crossed and uncrossed, respectively. Significant differences ( p<.0001) were found when calcium occlusion was less than 50% (87 vs. 31%), 51-75% (9.3 vs. 31.2%), and 76-100% (3.7 vs. 37.5%). Total calcium length in crossed lesion was 51.6 mm, and 92.8 mm in uncrossed lesions ( p = 0.10). No significant differences were noted for patient gender, occlusion location (proximal, middle, and distal superficial femoral artery), and kidney function. Conclusion The Ocelot catheter is an effective method to cross long Trans-Atlantic Inter-Society Consensus D lesions. Superficial femoral artery lesions longer than 17 cm and focal plaque morphology, specifically a total cross-sectional area of calcium and a calcium surface area greater than 50% were most predictive of failure to cross Trans-Atlantic Inter-Society Consensus D superficial femoral artery lesions. Computerized tomography angiography is an effective tool to predict success for crossing chronic total occlusions using optical coherence tomography technology and a critical consideration for patient selection.

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.
