Implementing a Preoperative Anemia Optimization Protocol for Cardiovascular Surgery Patients: A Quality Improvement Project.

BACKGROUND: Patients with anemia have poorer outcomes following cardiac surgery than do those without anemia. To improve outcomes, the Enhanced Recovery After Surgery cardiac recommendations include optimizing patients' condition, including treating anemia, before surgery. LOCAL PROBLEM: Despite implementing Enhanced Recovery After Surgery initiatives, a midwestern cardiothoracic surgery group recognized a care gap in preoperative patients with anemia. No standardized protocol was in use. METHODS: An anemia optimization protocol was developed for perioperative care of patients with anemia. Data from retrospective medical record review were analyzed to determine relationships between protocol use and secondary outcomes. The protocol was created using best evidence and expert consensus. Cardiac surgery and hematology specialists revised the protocol and agreed on a final version. The protocol was integrated into the consultation process for cardiac surgery patients. RESULTS: During the implementation period, 23 of 55 patients with anemia (42%) received interventions via the anemia optimization protocol. The mean quantity of packed red blood cells transfused perioperatively per patient was 1.9 U in the protocol group and 3.5 U in the nonprotocol group. In the subgroup of patients experiencing postoperative acute kidney injury, the mean increase in creatinine level was 0.65 mg/dL in the protocol group and 1.52 mg/dL in the nonprotocol group. Four patients in the protocol group (17%) and 6 patients in the nonprotocol group (19%) experienced postoperative acute kidney injury. CONCLUSION: Preoperative anemia is associated with poorer cardiac surgical outcomes. Incorporating the anemia optimization protocol into practice may mitigate the risk of postoperative complications for patients with anemia. Continued use of the protocol is recommended.

Elective Surgical Delays Due to COVID-19: The Patient Lived Experience.

BACKGROUND: This qualitative research explored the lived experiences of patients who experienced postponement of elective cardiac and vascular surgery due to coronavirus disease 2019 (COVID-19). We know very little about patients during the novel coronavirus pandemic. Understanding the patient voice may play an important role in prioritization of postponed cases and triage moving forward. METHODS: Utilizing a hermeneutical phenomenological qualitative design, we interviewed 47 individuals who experienced a postponement of cardiac or vascular surgery due to the COVID-19 pandemic. Data were analyzed and informed by phenomenological research methods. RESULTS: Patients in our study described 3 key issues around their postponement of elective surgery. Patients described robust narratives about the meanings of their elective surgeries as the chance to "return to normal" and alleviate symptoms that impacted everyday life. Second, because of the meanings most of our patients ascribed to their surgeries, postponement often took a toll on how patients managed physical health and emotional well-being. Finally, paradoxically, many patients in our study were demonstrative that they would "rather die from a heart attack" than be exposed to the coronavirus. CONCLUSIONS: We identified several components of the patient experience, encompassing quality of life and other desired benefits of surgery, the risks of COVID, and difficulty reconciling the 2. Our study provides significant qualitative evidence to inform providers of important considerations when rescheduling the backlog of patients. The emotional and psychological distress that patients experienced due to postponement may also require additional considerations in postoperative recovery.

Prioritizing cardiovascular surgical care in COVID-19 pandemic: Shall we operate or defer?

BACKGROUND: The coronavirus disease (COVID-19) has affected a large population across the world. Patients with cardiovascular disease have increased morbidity and mortality due to coronavirus disease. The burden over the health care system has to be reduced in this global pandemic to provide optimal care of patients with COVID-19, as well not compromising those who are in need of emergent cardiovascular care. METHODS: There is a very limited data published defining which cardiovascular procedures are to be performed or to be deferred in the COVID-19 pandemic. In this article, we have reviewed a few published guidelines regarding cardiovascular surgery in COVID-19 pandemics. CONCLUSION: After reviewing a few available guidelines regarding cardiovascular surgery in COVID-19, we conclude to perform only those surgeries which cannot be deferred to a certain period of time, to reduce the burden of the health care system of the country, provide optimal care to patients with COVID-19, and to protect health care workers and cardiovascular patients from COVID-19.

[Countermeasures and treatment for aortic acute syndrome with 2019 coronavirus disease].

The 2019 coronavirus disease(COVID-19) has cost a great loss to the health and economic property of Chines people. Under such a special circumstance, how to deal with such patients with acute aortic syndrome has become a serious challenge. Rapid diagnosis of concomitant COVID-19, safe and effective transportation, implementation of the interventional procedure, protection of vascular surgical team and postoperative management and follow-up of such patients have become urgent problems for us. Combined with the latest novel government documents, the literature and the experiences from Wuhan, we answered the above questions briefly and plainly. We also hope to inspire the national vascular surgeons to manage critical emergencies in vascular surgery and even routine vascular diseases with COVID-19, as a final point to limit the severe epidemic situation, and minimize the damage of COVID-19.

Artificial Neural Network: A Method for Prediction of Surgery-Related Pressure Injury in Cardiovascular Surgical Patients.

PURPOSE: The aim of this study was to build an artificial neural network (ANN) model for predicting surgery-related pressure injury (SRPI) in cardiovascular surgical patients. DESIGN: Prospective cohort study. SUBJECTS AND SETTING: One hundred forty-nine patients who had cardiovascular surgery were included in the study. This study was conducted in a 1000-bed teaching hospital in Eastern China where 250 to 350 cardiac surgeries are performed each year. METHODS: We performed a prospective cohort study among consecutive patients undergoing cardiovascular surgery between January and December 2015. The ANN model was built based on possible SRPI risk factors. The model performance was tested by a receiver operating characteristic curve and the C-index. A C-index from 0.5 to 0.7 is classified as having low accuracy, 0.7 to 0.9 as having moderate accuracy, and 0.9 to 1.0 as having high accuracy. We also compared the actual SRPI incidences based on the ANN stratification. RESULTS: Thirty-seven of 147 patients developed SRPIs, yielding an incidence rate of 24.8% (95% CI, 18.1-32.6). The C-index was 0.815, which showed the ANN model had a moderate prediction value for SRPI. According to the ANN model, the SRPI predicting incidence ranged from 6.4% to 67.7%. Surgery-related pressure injury incidences were significantly different among 3 risk groups stratified by the ANN (P < .05). CONCLUSION: We established an ANN model that provides moderate prediction of SRPI in patients undergoing cardiovascular surgical procedures. Identification and additional associated factors should be incorporated into the ANN model to increase its predictive ability.

Patients and physicians agree only partially in symptoms and clinical findings before and after treatment for varicose veins.

Objective Quality improvement in surgery has mainly been based on clinical database outcomes. This study compared variables from the patient-reported Aberdeen Varicose Vein Questionnaire with the Danish Clinical Vein Database, in order to reveal agreements and differences in symptoms and clinical findings. Methods In the period January-March 2011, 379 legs in 287 patients treated for varicose veins were registered in the Danish Clinical Vein Database and compared to the Aberdeen Varicose Vein Questionnaire. Results Patients and physicians agreed in reduction of symptoms after intervention with one or more complaints still present in 128 (93%) patients according to Aberdeen Varicose Vein Questionnaire compared to the Danish Clinical Vein Database with only 64 (47%) patients. Patients reported cosmetic complaints and teleangiectasies both before and after treatment (p < 0.001) more often than doctors. Conclusion The Aberdeen Varicose Vein Questionnaire has added valuable information to the dialogue between the doctor and patient on which symptoms expecting to improve and which not.

Swiss physicians' perspectives on advance directives in elective cardiovascular surgery.

BACKGROUND: When patients are incompetent, advance directives (AD) can help physicians take crucial medical decisions. However, prevalence remains low. The objective was to investigate physicians' perspectives and attitudes towards AD in order to determine potential targets for improvement. METHODS: Observational study by self-administered questionnaires to general practitioners and specialists potentially involved in the care of patients scheduled for major cardiovascular surgery in a Swiss canton. RESULTS: One-hundred and sixty-four 164 (40%) questionnaires were completed. Men: 116 (71%). Specialties: Internists: 73 (45%); General Practitioners: 50 (31%); Intensivists: 22 (13%); Cardiologists: 18 (12%). Eighty-five percent (138/162) physicians thought that AD were useful and 124/161 (77%) were ready to help patients write AD (to allow them to decide on their fate [115/124 {93%}] and to increase their ease in expressing their wishes [108/124 {87%}]). Men and cardiologists were least likely to do so. Factors associated with lower interest in promoting AD were not logistical but personal such as "the topic can induce fear (21/34 [62%]) or unease (16/34 [47%]), and lack of knowhow (15/34 [44])". 22/160 (14%) physicians had never heard about AD, especially men. CONCLUSION: Not all physicians knew the concept of AD. The majority thought that AD were useful and would help patients write them, in order to respect their autonomy. Personal-related factors such as feelings of inducing fear or harm patients were more important than logistic factors in impeding the promotion of AD. Emphasizing AD during medical school might present a potential target to increase AD prevalence, particularly in the preoperative setting.

[Diagnosis and treatment of aortic diseases : new guidelines of the European Society of Cardiology 2014]. / Diagnostik und Therapie von Aortenerkrankungen : Neue Leitlinien der Europäischen Gesellschaft für Kardiologie 2014.

In September 2014 the European Society of Cardiology issued guidelines for the diagnosis and treatment of aortic diseases in adults. Contrast-enhanced computed tomography (CT) represents the imaging modality of first choice as it is rapidly and almost ubiquitously available and can evaluate the entire aorta in a single-step examination. In patients with a high clinical suspicion of an acute aortic syndrome based on (family) history and symptoms, CT should be performed without further delay to confirm or refute the diagnosis. Diseases involving the ascending aorta remain a domain of open surgery, be it on an emergency basis in an acute type A dissection or electively in asymptomatic aneurysms with an aortic diameter >5.5 cm. The presence of risk factors (e. g. bicuspid aortic valve, Marfan syndrome and aortic dissection/rupture in the family history) may prompt earlier surgical repair at a lower threshold diameter. The treatment of descending aortic disease is primarily conservative including modification of cardiovascular risk factors. If indicated, endovascular aortic stent graft repair appears to be superior to open surgery for descending thoracic aortic disease or equivalent in the treatment of infrarenal abdominal aortic aneurysms. The management of aortic diseases related to genetic connective tissue diseases (e. g. Marfan syndrome, Loeys-Dietz syndrome and Ehlers-Danlos syndrome) is complex and requires special multidisciplinary expertise.
