Novice providers' success in performing lumbar puncture: a randomized controlled phantom study between a conventional spinal needle and a novel bioimpedance needle. BMC MEDICAL EDUCATION 2024; 24:520. [PMID: 38730411 PMCID: PMC11088096 DOI: 10.1186/s12909-024-05505-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 05/02/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Lumbar puncture (LP) is an important yet difficult skill in medical practice. In recent years, the number of LPs in clinical practice has steadily decreased, which reduces residents' clinical exposure and may compromise their skills and attitude towards LP. Our study aims to assess whether the novel bioimpedance needle is of assistance to a novice provider and thus compensates for this emerging knowledge gap. METHODS This randomized controlled study, employing a partly blinded design, involved 60 s- and third-year medical students with no prior LP experience. The students were randomly assigned to two groups consisting of 30 students each. They performed LP on an anatomical lumbar model either with the conventional spinal needle or the bioimpedance needle. Success in LP was analysed using the independent samples proportion procedure. Additionally, the usability of the needles was evaluated with pertinent questions. RESULTS With the conventional spinal needle, 40% succeeded in performing the LP procedure, whereas with the bioimpedance needle, 90% were successful (p < 0.001). The procedures were successful at the first attempt in 5 (16.7%) and 15 (50%) cases (p = 0.006), respectively. Providers found the bioimpedance needle more useful and felt more confident using it. CONCLUSIONS The bioimpedance needle was beneficial in training medical students since it significantly facilitated the novice provider in performing LP on a lumbar phantom. Further research is needed to show whether the observed findings translate into clinical skills and benefits in hospital settings.

Xie S, Grimstrup S, Nayahangan LJ, Wang Z, Wan X, Konge L. Using a novel virtual-reality simulator to assess performance in lumbar puncture: a validation study. BMC MEDICAL EDUCATION 2023; 23:814. [PMID: 37904177 PMCID: PMC10614418 DOI: 10.1186/s12909-023-04806-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 10/25/2023] [Indexed: 11/01/2023]
Abstract
BACKGROUND A lumbar puncture procedure's success depends on a competent physician minimizing the risk of failing to get a sample and avoiding complications such as post-dural headache. A new virtual-reality simulator might be helpful in deciding when a physician is competent to perform lumbar puncture. We aimed to investigate validity evidence for a simulator-based test in lumbar puncture and establish a pass/fail standard to allow a mastery learning training program. METHODS Validity evidence was investigated using Messick's framework by including participants who were novices, intermediates, or experienced in lumbar puncture. Each participant performed two lumbar puncture procedures on the simulator, and fifty-nine predefined simulator metrics were automatically recorded. Cronbach's alpha was used to explore internal consistency reliability. Intergroup comparisons were made using independent sample t-tests with Tukey's correction for multiple comparisons. The learning effect was explored using paired sample t-test analysis, and a pass/fail standard was established using the contrasting groups' method. RESULTS 73 novices, 18 intermediates, and 19 physicians performed the test resulting in a total of 220 procedures. 25 metrics (42.4%) had good discriminatory ability, and the reliability of these metrics was good, Cronbach's α = 0.81. The experienced physicians were significantly better than the novices (18.3 vs. 13.3, p < 0.001), and the pass/fail standard was established at 16 points. This standard resulted in 22 (30.1%) novices passing (i.e., false positives) and 5 (26.3%) physicians failing (i.e., false negatives). CONCLUSION This study provides validity evidence for a simulator-based test of lumbar puncture competence. The test can help ensure basic competence at the end of a simulation-based training program for trainees, i.e., a mastery learning training program.

Cureus 2023; 15:e34317. [PMID: 36860237 PMCID: PMC9970793 DOI: 10.7759/cureus.34317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/28/2023] [Indexed: 01/30/2023] Open
Abstract
Background Treatment-related pain and discomfort are two of the most common manifestations in children with acute lymphoblastic leukemia (ALL). Patients with ALL are usually treated with L-asparaginase (L-ASP) by intramuscular injection. Children receiving L-ASP chemotherapy must bear adverse reactions such as pain caused by intramuscular injections. The use of virtual reality (VR) distraction technology could be a non-pharmacological intervention to bolster patients' comfort and decrease anxiety and procedure-related pain within hospital settings. Methodology The study explored the potential benefits of VR as a psychological intervention to induce positive emotions and reduce pain levels in participants receiving L-ASP injections. Participants in the study had the opportunity to select a nature theme of their choosing during their treatment session. The study provided a noninvasive solution that promoted relaxation to reduce anxiety by shifting an individual's mood positively during treatment. The objective was met by measuring participants' mood and pain levels before and after the VR experience and participant satisfaction with the use of the technology. This mixed-methods study of children aged six to 18 received L-ASP between April 2021 and March 2022, using a Numerical Rating Scale (NRS) with sheer numbers ranging from 0 (no pain) to 10 (extreme or most pain possible). Semi-structured interviews were conducted to collect new data and explore participants' thoughts and beliefs about a particular topic. A total of 14 patients participated. Descriptive statistics and content analysis are used to describe the data analyzed. VR is an enjoyable distraction intervention for managing treatment-related pain in ALL with intramuscular chemotherapy. Results Eight of 14 patients found a reduction in perceived pain after wearing VR. During the intervention implementation, the primary caregivers felt that the patient's pain perception was more positive when using the virtual reality device, and there was less resistance and less crying. Conclusions This study describes changes and experiences associated with pain and physical discomfort in children with ALL receiving intramuscular chemotherapy. This teaching model is applied to developing medical personnel, providing information about the disease and daily care, and educating the participants' family members. This study may expand the usage of VR applications so that more patients can benefit from them.

Abstract
Virtual simulation (VS) as an emerging interactive pedagogical strategy has been paid more and more attentions in the undergraduate medical education. Because of the fast development of modern computer simulation technologies, more and more advanced and emerging VS-based instructional practices are constantly increasing to promote medical education in diverse forms. In order to describe an overview of the current trends in VS-based medical teaching and learning, this scoping review presented a worldwide analysis of 92 recently published articles of VS in the undergraduate medical teaching and learning. The results indicated that 98% of included articles were from Europe, North America, and Asia, suggesting a possible inequity in digital medical education. Half (52%) studies reported the immersive virtual reality (VR) application. Evidence for educational effectiveness of VS in medical students’ knowledge or skills was sufficient as per Kirkpatrick’s model of outcome evaluation. Recently, VS has been widely integrated in surgical procedural training, emergency and pediatric emergency medicine training, teaching of basic medical sciences, medical radiation and imaging, puncture or catheterization training, interprofessional medical education, and other case-based learning experiences. Some challenges, such as accessibility of VS instructional resources, lack of infrastructure, “decoupling” users from reality, as well as how to increase students’ motivation and engagement, should be addressed.
