Improving performance and self-efficacy of novice nurses using hybrid simulation-based mastery learning.

AIM: Acute chest pain is a commonly encountered symptom in hospital medical/surgical units; however, almost half of nurses in their second year of clinical experience in our facility have reported struggling to care for acute chest pain patients. We developed, implemented, and examined the effectiveness of a simulation-based, mastery learning clinical nursing educational program to improve self-efficacy and performance in caring for patients with acute chest pain. METHODS: The study adopted a single-site, single-cohort design using simulation-based performance assessment and self-efficacy surveys on a convenience sample of 37 second-year clinical nurse participants in multi-stage hybrid mastery learning educational intervention using asynchronous e-learning, and hands-on simulation training and assessment with feedback on caring for chest pain patients. Performance assessments and self-efficacy surveys were administered pre-, post-, and 5 months post-intervention. RESULTS: Clinical performance on the post- and 5 months follow-up assessments were significantly higher than those for the pre-test (P < .0001). The self-efficacy scores for the post- and the 5 months follow-up assessments were significantly higher than the pre-course scores (P < .0001). Participants' self-efficacy perceptions were positively correlated with their performances at 5 months post-intervention. CONCLUSION: Performance and self-efficacy of novice nurses in caring for acute chest pain patients improved significantly with the multi-stage hybrid mastery learning educational intervention, with improvements retained 5 months post-intervention. The results suggest the applicability of simulation-based mastery learning in a clinical setting for novice nurses to attain specific skills, and raise their self-perception of competence to care for patients in acute settings.

A Patient Safety Champion Program for Interprofessional Health Care Educators: Implementation and Outcomes.

INTRODUCTION: Health care educators are challenged with helping clinicians develop competencies beyond their foundational training. In health care systems where continuing professional development is not integral to practice, clinicians may have few opportunities. We describe the design, implementation, and evaluation of a professional development program in patient safety for Japanese clinical educators to acquire simulation instructional skills and become Patient Safety Champions at their organizations. METHODS: Mixed methods were used in a longitudinal pre/post study design. The Kirkpatrick evaluation model was used to evaluate outcomes of a workshop, overall program, on-site training experiences, and impact as Patient Safety Champions. Self-assessment data on skills and knowledge of patient safety, simulation instructional methods, interprofessional collaboration, and leadership were collected and analyzed. RESULTS: Eighty-nine percent of participants facilitated on-site patient safety training within 6 months of workshop completion. Skills and knowledge improvement were observed immediately postworkshop in four categories: patient safety, simulation instructional methods, interprofessional collaboration and communication, and leadership as a patient safety champion. Skills and knowledge increased at 6 months after facilitation of on-site safety training. Program mean satisfaction scores ranged from 84% to 92%. Mean Patient Safety Champion in-facility evaluations were 4.2 to 4.7 on a 5-point scale. DISCUSSION: High levels of knowledge, skill retention, and behavior change are attributed to goal setting, outcome-oriented pedagogy, and reflective sessions. The Patient Safety Champion model and experiential learning approach gave Japanese clinical educators in medicine, nursing, and pharmacy an opportunity to learn from each other in simulations reflecting the practice environment.

Triglyceride/low-density-lipoprotein cholesterol ratio is the most valuable predictor for increased small, dense LDL in type 2 diabetes patients.

BACKGROUND: Small, dense low-density lipoprotein (sd-LDL) increases in type 2 diabetes patients and causes arteriosclerosis. Non-high-density-lipoprotein cholesterol (non-HDL-C) is thought to be useful for predicting arteriosclerosis and sd-LDL elevation; however, there are no data about whether the triglyceride /low-density-lipoprotein cholesterol (TG/LDL-C) ratio is a valuable predictor for sd-LDL. METHODS: A total of 110 type 2 diabetes patients with hypertriglyceridemia were analyzed. No patients were treated with fibrates, but 47 patients were treated with statins. LDL-C was measured by the direct method. LDL-migration index (LDL-MI) using electrophoresis (polyacrylamide gel, PAG) was calculated, and a value ≥0.400 was determined to indicate an increase in sd-LDL. Simple regression analyses were carried out between LDL-MI and lipid markers. Receiver operating characteristic curves of lipid markers for predicting high LDL-MI were applied to determine the area under the curve (AUC), sensitivity, specificity, and cut-off point. RESULTS: LDL-MI correlated negatively with LDL-C (P = 0.0027) and PAG LDL fraction (P < 0.0001) and correlated positively with TGs, non-HDL-C, TG/LDL-C ratio, TG/HDL-C ratio, and non-HDL-C/HDL-C ratio among all study patients. Similar results were obtained for patients analyzed according to statin treatment. The AUCs (95% confidence interval) were 0.945 (0.884-1.000) for TG/LDL-C ratio and 0.614 (0.463-0.765) for non-HDL-C in patients without statins (P = 0.0002). The AUCs were 0.697 (0.507-0.887) for TG/LDL-C and 0.682 (0.500-0.863) for non-HDL-C in patients treated with statins. The optimal cut-off point for TG/LDL-C ratio for increased LDL-MI was 1.1 (molar ratio) regardless of statin treatment. The sensitivity and specificity of the TG/LDL-C ratio (90.0 and 93.9%, respectively) were higher than those of non-HDL-C (56.7 and 78.8%, respectively) in patients without statins. CONCLUSIONS: The TG/LDL-C ratio is a reliable surrogate lipid marker of sd-LDL and superior to non-HDL-C in type 2 diabetes patients not treated with statins.

A case of thyrotoxicosis-induced anemia in a patient with painless thyroiditis.

BACKGROUND: There have been several reports of secondary anemia associated with Graves' disease. There are no reports of secondary anemia resulting from thyrotoxicosis due to painless thyroiditis (silent thyroiditis). We report the case of a patient with pancreatic diabetes who developed anemia caused by thyrotoxicosis due to painless thyroiditis. CASE PRESENTATION: The patient was a 37-year-old man who visited the hospital complaining of fatigue, palpitations, and dyspnea. His hemoglobin was 110 g/l (reference range, 135-176), and mean corpuscular volume was 81.5 fl (81.7-101.6). His free thyroxine (FT4) was high, at 100.4 pmol/l (11.6-21.9); the free triiodothyronine (FT3) was high, at 27.49 pmol/l (3.53-6.14); TSH was low, at < 0.01 mIU/l (0.50-5.00); and TSH receptor antibody was negative. Soluble IL-2 receptor (sIL-2R) was high, at 1340 U/ml (122-496); C-reactive protein (CRP) was high, at 6900 µg/l (< 3000); and reticulocytes was high, at 108 109 /l (30-100). Serum iron (Fe) was 9.5 (9.1-35.5), ferritin was 389 µg/l (13-401), haptoglobin was 0.66 g/l (0.19-1.70. Propranolol was prescribed and followed up. Anemia completely disappeared by 12 weeks after disease onset. Thyroid hormones and sIL-2R had normalized by 16 weeks after onset. He developed mild hypothyroidism and was treated with L-thyroxine at 24 weeks. CONCLUSIONS: This is the first case report of transient secondary anemia associated with thyrotoxicosis due to painless thyroiditis. The change in sIL-2R was also observed during the clinical course of thyrotoxicosis and anemia, suggesting the immune processes in thyroid gland and bone marrow.

Case Report: Iliopsoas Hematoma during the Clinical Course of Severe COVID-19 in Two Male Patients.

Anticoagulation plays a major role in reducing the risk of systematic thrombosis in patients with severe COVID-19. Serious hemorrhagic complications, such as intracranial hemorrhage, have also been recognized. However, intra-abdominal hemorrhage is under-recognized because of its rare occurrence, despite high mortality. Here, we discuss two cases of spontaneous iliopsoas hematoma (IPH) likely caused by anticoagulants during the clinical course of COVID-19. We also explored published case reports to identify clinical characteristics of IPH in COVID-19 patients. The use of anticoagulants may increase the risk of lethal IPH among COVID-19 patients becsuse of scarce data on optimal dosage and adequate monitoring of anticoagulant effects. Rapid diagnosis and timely intervention are crucial to ensure good patient outcomes.

Umbilical catheterization training: Tissue hybrid versus synthetic trainer.

BACKGROUND: This study of umbilical catheterization deliberate practice training compared skill and knowledge outcomes of umbilical catheterization using a tissue-hybrid simulator (REAL) versus a synthetic simulated umbilical cord task trainer (ART). METHODS: This was a prospective randomized control study. Pediatric residents were randomized to REAL or ART umbilical catheterization deliberate practice training. Pre-post-training changes in skill performance and knowledge scores for REAL and ART groups were compared. Fidelity of REAL and ART were compared by neonatologists. RESULTS: Twenty-seven pediatric residents completed training. Post-training mean skill scores were improved compared to pre-test scores (REAL, P < 0.001; ART, P < 0.0001). Post-training skill, knowledge, and self-efficacy scores were not different between the REAL and ART groups. Fidelity of REAL was higher than ART for neonatologists (P < 0.01). CONCLUSIONS: The face validity of REAL was superior to ART, but resident umbilical cord deliberate practice training demonstrated no difference in skill, knowledge, and self-efficacy improvements between REAL and ART. Further studies on real patients are needed to evaluate the impact of using real or simulated umbilical cords for umbilical venous catheter/umbilical arterial catheter training.

Low level of serum HDL-cholesterol with increased sIL-2R predicts a poor clinical outcome for patients with malignant lymphoma and adult T-cell leukemia-lymphoma.

Low concentrations of high-density lipoprotein cholesterol (HDL-C) have been reported in patients with hematological malignancies. However, the proof of decreased HDL-C in hematological malignancies and its association with clinical outcomes remain unclear. We analyzed 140 Japanese patients with malignant lymphoma (ML) and adult T-cell leukemia-lymphoma (ATLL). HDL-C, LDL-C and soluble interleukin-2 receptor (sIL-2R) were measured. Treatment decisions were determined with established protocols. HDL-C was 0.98 ±â€¯0.45 mmol/l in patients and 1.51 ±â€¯0.35 mmol/l in controls (P < 0.001). LDL-C was lower in patients than in controls (2.76 ±â€¯0.96, 3.16 ±â€¯0.76 mmol/l, respectively, P < 0.001). HDL-C was the lowest in ATLL (0.81 ±â€¯0.37 mmol/l), modest in non-Hodgkin lymphoma (1.09 ±â€¯0.42 mmol/l) and the highest in Hodgkin's disease (1.14 ±â€¯0.68 mmol/l), (P = 0.0019). Inverse correlation was found between HDL-C and sIL-2R (r = -0.6584, P < 0.001). Categorized patients into 3 subgroups according to HDL-C (<0.52, 0.52-1.02 and ≥1.03 mmol/l), sIL-2R were the highest (median, 36,675; IQR, 17,180-92,600 U/mL) in patients with HDL-C < 0.52 mmol/l, modest (2386, 1324-8340) in HDL-C 0.52-1.02 mmol/l and the lowest (761, 450-1596) in HDL-C ≥ 1.03 mmol/l (P < 0.001). In Cox regression model, the lowest HDL-C levels, <0.52 mmol/l, were associated with poorer clinical outcome and the hazard ratio was 5.73 (95%CI, 3.09-10.50; P < 0.001). In Kaplan-Meier analysis according to HDL-C tertiles (<0.78, 0.78-1.10 and ≥1.11 mmol/l), patients with lowest HDL-C tertile showed inferior overall survival with a median follow-up of 23 months (P < 0.001). We concluded that cytokine-induced low levels of HDL-C in patients with ML and ATLL has independent prognostic significance, and suggesting an early indicator of poorer outcome.

Successful conservative management of a case of caustic esophagitis based on computed tomography assessment.

Case: We describe the case of a female patient who ingested approximately 100 mL of toilet bowl cleaner containing 9.5% hydrochloric acid in a suicide attempt. Upon admission for hematemesis and epigastric pain, she was alert and oriented with stable vital signs. Initial contrast-enhanced computed tomography (CT) demonstrated edematous changes with no evidence of upper gastrointestinal tract perforation. Endoscopy was not performed owing to the high risk of perforation. We managed this patient conservatively. Repeat contrast-enhanced CT revealed mediastinal emphysema on day 2, which resolved by day 6. The patient was subsequently discharged with no apparent strictures of the upper gastrointestinal tract. Outcome: Surgical interventions are frequently required following the ingestion of large amounts of highly concentrated hydrochloric acid; however, this patient was successfully managed conservatively. Conclusion: Contrast-enhanced CT is useful in the assessment of the respiratory and digestive systems and the prediction of potential complications.
