Healthcare (Basel) 2024; 12:1251. [PMID: 38998786 PMCID: PMC11241498 DOI: 10.3390/healthcare12131251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/10/2024] [Accepted: 06/16/2024] [Indexed: 07/14/2024] Open
Abstract
BACKGROUND Transabdominal ultrasound is used to detect fecal impaction, but the rectum is difficult to visualize without bladder urine or with gastrointestinal gas. OBJECTIVE We developed a transgluteal cleft approach that is unaffected by these factors and sought to determine if our ultrasound method could detect and classify fecal matter in the lower rectum using this approach. METHODS We classified ultrasound images from hospitalized patients into four groups: Group 1 (bowed and rock-like echogenic areas), Group 2 (irregular and cotton candy-like hyperechoic areas), Group 3 (flat and mousse-like hyperechoic areas), and Group 4 (linear echogenic areas in the lumen). Stool characteristics were classified as hard, normal, and muddy/watery. Sensitivity and specificity were determined based on fecal impaction and stool classification accuracy. RESULTS We obtained 129 ultrasound images of 23 patients. The sensitivity and specificity for fecal retention in the rectum were both 100.0%. The recall rates were 71.8% for Group 1, 93.1% for Group 2, 100.0% for Group 3, and 100.0% for Group 4. The precision rates were 96.6% for Group 1, 71.1% for Group 2, 88.9% for Group 3, and 100.0% for Group 4. Our method was 89.9% accurate overall. CONCLUSION Transgluteal cleft approach ultrasound scanning can detect and classify fecal properties with high accuracy.

NURSING REPORTS 2024; 14:140-147. [PMID: 38251190 PMCID: PMC10801476 DOI: 10.3390/nursrep14010012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/27/2023] [Accepted: 12/28/2023] [Indexed: 01/23/2024] Open
Abstract
Ultrasound hip screening is suitable for the early identification of developmental dysplasia of the hip (DDH). Newborn and infant home visits are good opportunities for hip screening in the community, but studies focusing on nurse-led screenings are lacking. Based on a pre-post design, this study aims to develop and evaluate an ultrasound training program to improve nurses' assessment skills in detecting DDH cases during newborn and infant home visits. Said educational program will include e-learning, hands-on seminars, and clinical training. The primary outcome will be the success rate of imaging standard planes (standardized images for hip assessment) in clinical training. The secondary outcomes will include knowledge test results, objective structured clinical examination scores, time required for imaging, and inter-rater reliability between nurses and physicians. The educational program will address the issue of missed and late detection of DDH cases in resource-limited communities. This study will demonstrate the feasibility of procedures and the effectiveness of the educational program in 2024. The protocol was registered in the University Hospital Medical Information Network Clinical Trial Registry before starting the study (no. UMIN000051929, 16 August 2023).

Abstract
BACKGROUND Asynchronous e-learning has become the mainstream choice since the transformation of learning formats by the coronavirus disease-19 pandemic. This scoping review aimed to examine the technologies used in asynchronous e-learning for the continuing education of clinical nurses and their modes of delivery and effectiveness. METHODS This scoping review covered the period between 2011 and 2023. Six databases were searched for relevant studies following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) protocol. RESULTS Sixty articles met the inclusion criteria. There was a noticeable trend toward using diverse technology-enabled and enhanced training (TEET) options after 2017. The enabling technological approaches, such as interactive online modules (25 articles) and video modules (25 articles), are described in the articles. The most commonly used enhancing technologies were scenario-based learning (nine articles), resource access (eight articles), computer simulation or virtual reality (three articles), and gamification (three articles). Among the outcomes, knowledge acquisition was the most commonly examined outcome (41 articles). CONCLUSIONS Notably, many interactive TEET modules were used in asynchronous e-learning. There were few studies on gamification, computer simulation or virtual reality, and scenario-based learning (techniques to enhance intrinsic motivation further). However, the adoption of asynchronous e-learning with advanced TEET options is anticipated to increase in the future. Therefore, objective outcome measures are required to determine the effects of such learning methods on knowledge acquisition and behavioral changes.

Abstract
BACKGROUND The effectiveness of point-of-care ultrasound (POCUS) for nurses has been demonstrated; however, only a limited number of nurses have been trained to perform POCUS. This article reports on a POCUS train-the-trainer program for nurse educators that targets lower urinary track dysfunction. METHOD Nurse educators (n = 38) were invited to participate in a POCUS train-the-trainer program, which comprised an e-learning module and a hands-on seminar. Acquisition of knowledge and skills were assessed after the module and seminar, respectively. RESULTS Questions from the "Basic Knowledge of Ultrasonography" test were answered correctly at a rate of 93.0% (SD, 8.5%). Measured values of bladder urinary volume using ultrasonography were in close agreement with actual values. All of the participants indicated that the program covered the content necessary to use in practice. CONCLUSION The POCUS train-the-trainer program equips nurse educators with the knowledge and skills needed for training nurses at their institutions. [J Contin Educ Nurs. 2021;52(8):375-381.].

SENSORS 2021; 21:s21113712. [PMID: 34073586 PMCID: PMC8199027 DOI: 10.3390/s21113712] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/16/2021] [Accepted: 05/24/2021] [Indexed: 11/16/2022]
Abstract
(1) Background: Ultrasound provides a radiation-free and portable method for assessing swallowing. Hyoid bone locations and displacements are often used as important indicators for the evaluation of swallowing disorders. However, this requires clinicians to spend a great deal of time reviewing the ultrasound images. (2) Methods: In this study, we applied tracking algorithms based on deep learning and correlation filters to detect hyoid locations in ultrasound videos collected during swallowing. Fifty videos were collected from 10 young, healthy subjects for training, evaluation, and testing of the trackers. (3) Results: The best performing deep learning algorithm, Fully-Convolutional Siamese Networks (SiamFC), proved to have reliable performance in getting accurate hyoid bone locations from each frame of the swallowing ultrasound videos. While having a real-time frame rate (175 fps) when running on an RTX 2060, SiamFC also achieved a precision of 98.9% at the threshold of 10 pixels (3.25 mm) and 80.5% at the threshold of 5 pixels (1.63 mm). The tracker's root-mean-square error and average error were 3.9 pixels (1.27 mm) and 3.3 pixels (1.07 mm), respectively. (4) Conclusions: Our results pave the way for real-time automatic tracking of the hyoid bone in ultrasound videos for swallowing assessment.

Diagnostic accuracy of ultrasound examination in detecting aspiration and pharyngeal residue in patients with dysphagia: A systematic review and meta-analysis. Jpn J Nurs Sci 2021; 18:e12396. [PMID: 33843140 DOI: 10.1111/jjns.12396] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 09/06/2020] [Accepted: 09/10/2020] [Indexed: 02/01/2023]
Abstract
AIM To estimate diagnostic accuracy of ultrasonography for detecting aspiration and pharyngeal residue in patients with dysphagia. METHODS A systematic search was conducted in MEDLINE (via PubMed), CINAHL, EMBASE, Ichushi-Web, and Cochrane Library databases to identify articles that showed diagnostic accuracy of ultrasonography for detecting aspiration and residue published in English and Japanese until August 2019. Cross-sectional studies, case-control studies, and cohort studies were included. The diagnostic accuracy results were extracted and the pooled estimated sensitivity and specificity were calculated. The risk of bias of the studies was assessed using the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies 2. The certainty of the evidence was assessed using the Grades of Recommendation Assessment, Development, and Evaluation methodology. RESULTS Five studies were included in this review. The pooled estimated sensitivity and specificity for detecting aspiration were 0.82 (95% CI: 0.72-0.89) and 0.87 (95% CI: 0.81-0.92), respectively. One study was included that evaluated ultrasound assessments of pharyngeal residue. The sensitivity and specificity were 0.62 (95% CI: 0.32-0.86) and 0.67 (95% CI: 0.22-0.96), respectively. The certainty of the evidence was low and very low for the diagnostic accuracy of aspiration and pharyngeal residue, respectively. CONCLUSION Ultrasound is a non-invasive method with good sensitivity and specificity in detecting aspiration as well as reference standards. While risk of bias and small number of studies limited the strength of this systematic review, our results suggested that ultrasound examination was useful as a bedside screening tool for detecting aspiration.
