Exploring Australian emergency department clinicians' knowledge,attitudes and adherence to the national peripheral intravenous catheter clinical care standard: A cross-sectional national survey

Objective

This study aimed to (i) capture clinicians' knowledge, attitude and adherence to the first Australian national peripheral intravenous catheter (PIVC) Clinical Care Standard, (ii) examine the instrument performance of the knowledge related questions and (iii) explore the educational needs for, and barriers to, Standard adherence among Australian ED clinicians.

Methods

A cross-sectional national online survey was conducted from March to June 2022, using a snowball sampling method. The survey used 5-point Likert scales and multiple-choice questions to capture respondents' knowledge, attitude and adherence to the Standard as well as the educational needs for, and barriers to, Standard adherence.

Results

In total, 433 ED nurses and doctors responded. Although nearly half (n = 206, 47.6%; 95% confidence interval [CI] 55.5–65.8) of respondents claimed that they were unfamiliar with the Standard, questions on PIVC knowledge yielded that most respondents had adequate knowledge of most of the key standards. Respondents' attitudes towards multiple intravenous insertion attempts and ongoing PIVC competency monitoring are not in agreement with the Standard. Self-reported practices regarding routine insertion of idle catheters (55%; 95% CI 49.9–59.9), using antecubital fossa as the first insertion site (84%; 95% CI 80–87), insertion without confidence (46%; 95% CI 41.2–51.1) and lack of routine reviewing the ongoing needs of PIVC (40%; 95% CI 35.3–45.1) were not aligned with the Standard. Unawareness of the Standard and non-practical recommendations were rated as the top barriers to Standard adherence.

Conclusion

The findings of the survey suggest that the Standard may need modification to align with the needs of ED clinicians. Future studies need to explore the applicability and relevancy of some recommendations in the ED settings as they may cause low adherence to the Standard.     

Staff knowledge,attitudes and practices regarding glycaemic management in adult intensive care units: A national survey

Background

Hyperglycaemia is common in critically ill adult patients. Many studies have identified the content, methods, and effects of glycaemic control but have not explored the effects of knowledge, attitudes, and practices (KAP) on glycaemic control in critically ill adults. Various factors also influence the KAP of intensive care unit (ICU) staff.

Aims

To assess KAP regarding glucose management for critically ill adults among nurses and medical professionals and identify the factors that influence their KAP in ICUs.

Methods

A multicentre cross-sectional survey.

Results

In total, 403/459 (response rate: 87.8%) participants from ICUs in nine tertiary hospitals in China participated in this study, 82.4% of whom were female and 93.4% of whom were nurses. The mean work experience was 8.88 years, and the mean critical care experience was 6.59 years. The scoring rate for the three dimensions of knowledge, attitudes, and practices were 82.35%, 87.69%, and 76%, respectively. We did not find any other factors affecting the KAP scores except for the level of knowledge awareness (p < 0.001), awareness of the importance (p < 0.001), and training for glucose control (p = 0.004).

Conclusion

ICU staff KAP regarding glycaemic control in critically ill adults among ICU professionals were acceptable in China. However, ICU professionals' current knowledge regarding nutrition, glucose variability, and skills related to glucose management could be improved.

Relevance to Clinical Practice

ICU educators should provide more skills-related training for healthcare professionals in the glycaemic management of critically ill adults. Moreover, the process of managing blood glucose in adult ICU patients is a collaborative, multidisciplinary team effort, with monitoring and feedback required during implementation.

Computed tomography diagnosis of tracheobronchopathia osteochondroplastica

Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease characterized by the presence of osseous and cartilaginous submucosal nodules projecting into the tracheobronchial tree. Most cases are asymptomatic and discovered incidentally at post‐mortem. We identified a case of TO on thoracic spiral CT and confirmed the diagnosis on bronchoscopy. This article reviews the imaging characteristics of TO, and shows the 3‐D virtual bronchoscopic and multiplanar reconstruction appearances of TO.     

The role of thyroid FNA cytology in pediatric malignant lesions: An overview of the literature

When one is dealing with pediatric thyroid lesions, fine‐needle aspiration is the first diagnostic tool for the correct characterization of these nodules. Despite the apparent infrequency of thyroid cancers in children, recent data from the National Cancer Institute prove that the incidence has been increasing, especially in adolescents. With the same data, a higher prevalence of well‐differentiated cancers can be estimated, with 90% diagnosed as papillary thyroid cancer. Nonetheless, some publications have demonstrated that some specific malignant variants are more frequent in children and have a more aggressive behavior that justifies the increased number of surgical procedures. For this reason, the American Thyroid Association recommends the performance of neck ultrasonography and fine‐needle aspiration cytology (FNAC) for the evaluation of pediatric thyroid nodules. Accordingly, as reported in adult thyroid series, several authors have documented the high sensitivity and diagnostic accuracy of FNAC in pediatric series; they have also shared the same problematic issues encountered in adult populations, mostly in the diagnosis of indeterminate lesions. To provide precise clinical and/or surgical management, the correct cytological identification of specific malignant histotypes/entities should be mandatory because lymph nodes, distant metastases, and extrathyroidal infiltration are more frequent within specific histotypes. A perusal of the literature shows that their identification has not been extensively studied and investigated in cytological samples. This review focuses on the analysis of data from the literature on the evaluation of malignancies and specific morphological features in pediatric thyroid lesions.
