Problem

Arterial blood gasses (ABGs) account for an estimated 10-20% of all costs during an ICU stay. Non-clinically indicated ABGs increased costs of care, lengths of stay, ventilator days, and line days, increasing the risk of adverse outcomes in already vulnerable critically ill patients. A cardiac surgery intensive care unit (CSICU) within a large urban mid-Atlantic academic medical center accounted for 31% of the entire institution's ABG analyses between 2018-2019, was identified as a top utilizer due to inappropriate ordering practices compared to current guidelines.

Purpose

The purpose of this quality improvement project was to implement an algorithm using evidence-based guidelines that identified appropriate standardized clinical indications for ABGs, with the intention of reducing non-clinically indicated blood gas analyses orders within the CSICU. Anticipated outcomes of this practice change included decreasing the total volume of ABGs sent, resulting in reduced costs of care, lengths of stay, and improved morbidity and mortality rates.

Methods

An evidence-based ABG indication algorithm was created focusing on acute changes in oxygenation, ventilation, acid base balance; changes in hemodynamics, post-operative baseline, and for patient ABGs to correlate with extra-corporeal membranous oxygenation values. Routine ABGs for monitoring were eliminated. Implementation occurred over fourteen-weeks in the fall of 2020 following staff and provider education. Training emphasized the use of non-invasive monitoring such as pulse-oximetry and capnography. Compliance and gross laboratory totals and indications were obtained from weekly auditing.

Results

There was an 8.8% reduction in ABGs obtained and 32% decrease in ABGs per patient day. The most common indications were extra-corporeal membranous oxygenation (ECMO)-correlated ABGs, post-operative, and changes in oxygenation and/or ventilation; 7.8% were non-indicated.

Conclusions

Implementation of an ABG indication algorithm resulted in fewer ABGs sent, mostly due to a reduction in routine monitoring, and ABGs were more likely to be clinically indicated in response to an acute concern. Implementing an ABG indication algorithm is safe, feasible, and can lead to significant cost reductions for the institution.

Introduction

Chronic venous insufficiency (CVI) manifests in various clinical presentations ranging from asymptomatic but cosmetic problems to severe symptoms, such as lower limb edema, skin trophic changes, and ulceration. CVI substantially affects the quality of life and work productivity of the patients. Ayurveda, an ancient traditional medicine in India, evaluates the various pathological stages of CVI with a wide range of pathological conditions such as Siragranthi (venous abnormalities), Raktavaritavāta (disorders of vāta occluded by rakta ∼ blood), ApanaVaigunya (vitiated apānavāyu), Arsha (hemorrhoids), VataRakta (rheumatism due to rakta), Kushtha (integumentary disease) and Dushta Vrana (putrefied wound) depending upon the presentations of the patient. Ayurvedic texts mention Terminalia arjuna as a potential herb for treating various conditions related to the circulatory system. The drug is an effective anti-inflammatory, anti-oxidant, and anti-hypertensive and has a definite role in improving cardiovascular hemodynamics and wound healing. These attributes suggest that the potential of Terminalia arjuna needs to be explored as a promising venoactive drug.

Methods

This prospective observational study included 25 patients (31 limbs) with CVI who were treated with Tab Terminalia arjuna (Bark extract of Terminalia arjuna in a dose of 500 mg, given twice a day) and were observed on two visits on day 30 and day 90. Follow-up was carried out for three months to evaluate post-treatment complications or adverse effects. The clinical outcome assessment was done using Venous Clinical Severity Score (VCSS), and clinical grading was performed using clinical classification (C0 – C6) of CEAP (Clinical–Etiology–Anatomy–Pathophysiology) classification.

Results

The median VCSS score (of both limbs) during the third visit was comparatively lower than the first, with a statistically significant improvement at 0.05 level. Further, there was a substantial positive improvement in the clinical classification of CEAP among the patients in pre and post treatment phase.

Conclusion

The prospective observational study shows that Tab Terminalia arjuna is safe and effective in CVI, reducing the symptoms like pain, edema, inflammation, pigmentation, induration and also expediting ulcer healing.

Introduction

Screening for cardiovascular disease (CVD) followed by preventive medication is expected to reduce CVD (2,3,5). However, insufficient medication adherence may affect screening effectiveness (11-12). It remains uncertain which interventions are suitable to support citizens in their decision-making about taking CVD preventive medication.

Objective

We evaluated if and how three nurse-led telephone follow-up (TFU) calls supported citizens in making informed decisions regarding CVD preventive medication and thereby potentially strengthened their medication adherence.

Methods

Employing a theory-based evaluation design inspired by Dahler-Larsen (39-41), we developed and tested a programme theory describing if and how the TFU calls supported medical decision-making and potentially improved medication adherence. Data were collected via telephone.

Findings

We analysed 61 TFU calls collected between May 2017 and April 2019 and found that TFU calls supported participants’ reflections on preventive medication. TFU calls supported informed decision-making regarding initiating medication, allowing participants to consider personal preferences and values, including both opting for and abstaining from medication. The content of the TFU calls revolved around four crucial themes: I) understanding the purpose of taking the medicine; II) meaningfulness and joint reflection support the decision; III) relation to healthcare professionals; and IV) taking medication for the first time.

Conclusion

TFU calls effectively supported citizens' understanding and addressed their needs. Trusted healthcare professionals' recommendations were preferred for decisional support. Initiating CVD preventive medication was particularly challenging for citizens who had not previously taken such medication. We recommend scheduling TFU calls early: the first after one week, the second after one month and the third after six months.

The purpose of this study was to assess the efficacy of early cognitive training in enhancement of cognitive function in stroke patients. This research used a quasi-experimental design, 45 patients were divided into two groups, and sequential sampling was employed. The experimental group (n = 22) received two weeks of early cognitive training six times per week, whereas the control group (n = 23) received regular hospital care. The Indonesian version of the Montreal Cognitive Assessment was used to evaluate cognitive function (MoCA-Ina). On the second day of therapy, pre-test data were taken, and post-test data were gathered after the intervention. Statistical test outcomes The MoCA-Ina score changed considerably between the intervention and control groups (p = 0.000 and p = 0.003, respectively). Several tests determined that the score was p = 0.017; the score after the intervention was substantially different between the two groups. It means cognitive function improves after exercise in the acute phase.

Introduction

The Walking Impairment Questionnaire (WIQ) is a common and easy-to-use assessment of walking incapacity in people with claudication due to peripheral artery disease (PAD). It has four subscales: pain severity, walking distance, walking speed, and ability to climb stairs. It has not been translated into Gujarati, which limits its use in Indian subjects.

Aim

This study aims to translate and assess the validity and reliability of a Gujarati version of WIQ.

Materials and Methods

This study had three phases: 1. Forward and backward translation and Cultural adaptation of WIQ into the Gujarati language by two independent translators, 2. Face and content validation by six clinical reviewers and 10 participants with PAD and Type II diabetes, 3. Concurrent and construct validity, test-retest reliability, and internal consistency of Gujarati, the WIQ was assessed on 160 participants with PAD and Type II diabetes who had a mean Ankle Brachial Index (standard deviation) <0.40 (0.1). The concurrent and construct validity of the WIQ was analyzed by correlating the WIQ distance and speed score with 6-minute walk distance (6MWD) and speed and WIQ total score with the Medical Outcome Study Questionnaire Short Form 36 (SF-36) score using Pearson's correlation coefficient. Test-retest reliability was analyzed using an intraclass correlation coefficient (ICC) with a seven-day interval between two questionnaire applications. Internal consistency of the total WIQ score was determined using Cronbach's alpha.

Results

Following translation, the Gujarati WIQ was considered acceptable and understandable by people with PAD. There was excellent correlation between the WIQ distance score and 6-minute walk test distance (r = 0.95, P < .05)) , the WIQ speed score and 6-minute walk test speed score (r = 0.89, P < .05)) and the Gujarati WIQ total score and total score of physical functioning domain of SF- 36 (r = 0.99, P < .05). There was excellent test-retest reliability over 7 days for total WIQ score (ICC = 0.94). The Cronbach's alpha for internal consistency of 0.97 for total WIQ score were excellent. This demonstrates the sufficient homogeneity of the total questionnaire.

Conclusion

The Gujarati version of the WIQ is reliable and valid and can be used to assess self-reported walking impairment in Gujarati-speaking people with PAD and Type II Diabetes.

Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), has been an increasingly common post-surgical complication for surgical patients. In the United States, VTE has become a leading cause of preventable hospital death with more than half occurring after discharge and are directly linked to a recent (within 30 days) hospitalization or surgery [1]. In large, hospital-associated/acquired VTE (HA-VTE) are preventable through measures such as the use of risk stratification tools and chemoprophylaxis. The project institution, a community, academic, medical center, for multiple years has consistently remained a high outlier for postoperative VTE. Also, the choice of VTE chemoprophylaxis in surgical patients at the time of discharge depended on, and varied between, the individual prescribing physician. The goal was to implement and determine the efficacy of a standardized intervention tool, the Caprini risk assessment model (RAM), for reducing postoperative VTE complications and its influence on the physician's prescription of enoxaparin at discharge. Results: Risk assessment scoring pre-operatively increased from 0% baseline to 26.3% at Plan-Do-Study-Act (PDSA) cycle 1 and demonstrated a statistically significant change (p-value = 0.006). Risk assessment scoring pre-operatively was 42.9% by PDSA cycle 2 but was not statistically significantly different from PDSA cycle 1. Risk assessment scoring post-operatively (for eligible patients) remained the same throughout all three cycles at 0%. Appropriate prescription of anticoagulation declined from baseline (12.5%) to PDSA cycle 1 (0%), and improved at PDSA cycle 2 (33.3%), however no differences were significant (p-value 0.302). The National Surgical Quality Improvement Project (NSQIP) database showed a decline in VTE occurrences at the projects institution from baseline (1.02%, 6 occurrences, 2021) to PDSA cycle 2 (0.92%, 4 occurrences, 2022) when compared to the national benchmark (1.0%) for the first time since 2018. Given the significant national problem HA-VTE pose to the public, and the rise in occurrences, this quality improvement (QI) project is clinically relevant.

Background and Aim

Patients with Marfan syndrome, who present with a variety of symptoms and complex psychosocial problems, require interprofessional collaboration in their care. However, it is unclear how health care providers contribute to interprofessional collaboration for these patients. The purpose of this study was to determine the characteristics of interprofessional collaboration for patients with Marfan syndrome in the cardiovascular field.

Methods

Semi-structured interviews were conducted with health care specialists (5 physicians, 2 nurses, and 3 certified genetic counselors) were analyzed qualitatively.

Results

Based on the medical collaboration for the management of cardiovascular complications in patients and their relatives, interprofessional collaboration was identified, such as collaboration and cooperation between physicians and certified genetic counselors, and nursing practice to facilitate interprofessional collaboration. In addition, issues such as difficulties in dealing with and coordinating medical care for noncardiovascular complications, lack of specialist physicians, and lack of opportunities to collaborate with nurses were identified.

Conclusions

Effective interprofessional collaboration requires the acquisition of Marfan syndrome and genetic knowledge by healthcare providers and the development of a healthcare delivery system based on departments that can provide leadership. In addition, the assignment of nurses to work across organizational boundaries and effective collaboration between genetic counselors and nurses should be considered.

Objective

The use of medical compression stockings (MCS) in patients with peripheral arterial disease (PAD) and diabetes is the subject of an ongoing critical debate. While reducing leg edema of various origins by improving venous back flow, there is a concern about additional arterial flow obstruction when compression therapy is applied in pre-existing PAD. The aim of this study is to obtain further information on the use of class I MCS in patients with advanced PAD and to evaluate the framework conditions for a safe application.

Methods

The total collective (n = 55) of this prospective, clinical cohort study consisted of 24 patients with PAD Fontaine stage IIb and higher studied before revascularization, of whom 16 patients were examined again after revascularization, and 15 healthy participants included for reference. The microperfusion of the lower extremity of all participants was examined in a supine, elevated, and sitting position using the oxygen to see (O2C) method.

Results

The results indicate that leg positioning had the strongest influence on microcirculation (SO2 and flow: p = 0.0001), whereas MCS had no significant effect on the perfusion parameters (SO2: p = 0.9936; flow: p = 0.4967) and did not lead to a deterioration of values into critical ranges.

Conclusion

Mild medical compression therapy appears to be feasible even in patients with advanced PAD. Larger studies are warranted to observe any long-term effects, in particular for the treatment of reperfusion edema after revascularization.

Background

Peripheral arterial disease (PAD) is common in HIV patients and can be diagnosed noninvasively using the ankle-brachial index (ABI). The burden of PAD has not been investigated in Ghanaian HIV patients. We investigated the prevalence and risk factors associated with PAD in HIV patients at a periurban hospital in Ghana.

Methods

In a case-control design, ABI was measured in 158 cART-treated HIV patients, 150 cART-naïve HIV patients and 156 non-HIV controls with no clinical symptoms of CVDs. PAD was defined as ABI ≤ 0.9. A structured questionnaire was used to collect socio-demographic and clinical data. Fasting venous blood samples were collected to measure plasma levels of glucose, lipid profile, and CD4+ lymphocytes.

Results

The prevalence of PAD was 13.9% among cART-treated HIV patients, 21.3% among cART-naïve HIV patients, and 15.4% among non-HIV controls. Patients with PAD had increased odds of having low CD4+ cell counts [OR (95% CI) = 3.68 (1.41–12.85)]. In cART-treated HIV patients, those on TDF-based [5.76 (1.1–30.01), p = 0.038] and EFV-based [9.28 (1.51–57.12), p = 0.016] regimens had increased odds of having PAD.

Conclusion

In our study population, there was no difference in the prevalence of PAD between cART-treated HIV patients compared to cART-naïve HIV patients or non-HIV controls. Having a low CD4 cell count and being on TDF- or EFV-based regimens were associated with an increased likelihood of having PAD.
