Prospective evaluation of patient-reported anxiety and experiences with adaptive radiation therapy on an MR-linac. Tech Innov Patient Support Radiat Oncol 2024; 29:100240. [PMID: 38445180 PMCID: PMC10912905 DOI: 10.1016/j.tipsro.2024.100240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 02/13/2024] [Accepted: 02/26/2024] [Indexed: 03/07/2024] Open
Abstract
Purpose An integrated magnetic resonance scanner and linear accelerator (MR-linac) was implemented with daily online adaptive radiation therapy (ART). This study evaluated patient-reported experiences with their overall hospital care as well as treatment in the MR-linac environment. Methods Patients pre-screened for MR eligibility and claustrophobia were referred to simulation on a 1.5 T MR-linac. Patient-reported experience measures were captured using two validated surveys. The 15-item MR-anxiety questionnaire (MR-AQ) was administered immediately after the first treatment to rate MR-related anxiety and relaxation. The 40-item satisfaction with cancer care questionnaire rating doctors, radiation therapists, the services and care organization and their outpatient experience was administered immediately after the last treatment using five-point Likert responses. Results were analyzed using descriptive statistics. Results 205 patients were included in this analysis. Multiple sites were treated across the pelvis and abdomen with a median treatment time per fraction of 46 and 66 min respectively. Patients rated MR-related anxiety as "not at all" (87%), "somewhat" (11%), "moderately" (1%) and "very much so" (1%). Positive satisfaction responses ranged from 78 to 100% (median 93%) across all items. All radiation therapist-specific items were rated positively as 96-100%. The five lowest rated items (range 78-85%) were related to general provision of information, coordination, and communication. Overall hospital care was rated positively at 99%. Conclusion In this large, single-institution prospective cohort, all patients had low MR-related anxiety and completed treatment as planned despite lengthy ART treatments with the MR-linac. Patients overall were highly satisfied with their cancer care involving ART using an MR-linac.

Study on the positivity rate and influencing factors of anxiety in pregnant women during the first fetal magnetic resonance examination: A cross-sectional study. PLoS One 2024; 19:e0297177. [PMID: 38252667 PMCID: PMC10802940 DOI: 10.1371/journal.pone.0297177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 12/30/2023] [Indexed: 01/24/2024] Open
Abstract
OBJECTIVE This study investigated the positive rate and related influencing factors of anxiety screening in pregnant women during the first fetal magnetic resonance examination. METHODS A total of 303 pregnant women who met the criteria for magnetic resonance pregnancy examination in a Grade III maternity hospital from December 2021 to December 2022 were included by the convenience sampling method. A cross-sectional survey was conducted before the examination using the General Situation Questionnaire and Self-rating Anxiety Scale (SAS). RESULTS The positive rate of anxiety was 31.02% (94/303), and the average score of anxiety was 45.71±9.84. Univariate analysis results showed that age, educational level, occupation, place of residence, per capita monthly income, and number of pregnancies were related to the anxiety status of pregnant women in the fetal magnetic resonance examination (P<0.05). The results of logistic regression analysis showed that the factor of college degree [OR: 2.168, 95% CI: (1.119, 4.273)] in the classification of cultural level and country factor [OR: 2.162, 95% CI: (1.066, 4.385)] in the classification of place of residence had an impact on the anxiety score of pregnant women in the fetal magnetic resonance examination (P<0.05). CONCLUSIONS The positive rate of anxiety screening of pregnant women before the first prenatal magnetic resonance examination is high. A low education level and living in the countryside will increase the probability of anxiety in pregnant women during magnetic resonance examination. Based on the above research results, it is suggested that medical institutions pay attention to the mental health of pregnant women, improve mental health care services, and reduce the adverse psychological problems caused by prenatal examination.

Hudson DM, Heales C. "I think this could be a big success" - A mixed methods study on practitioner perspectives on the acceptance of a virtual reality tool for preparation in MRI. Radiography (Lond) 2023; 29:851-861. [PMID: 37406474 DOI: 10.1016/j.radi.2023.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 06/17/2023] [Accepted: 06/19/2023] [Indexed: 07/07/2023]
Abstract
INTRODUCTION A key part of a radiographer's role within MRI is providing the required emotional support to help patients succeed with a scan. Being informed is important; whilst information leaflets and videos are commonly used, these can be limited in their representation of the experience. Virtual reality tools are being shown to reasonably replicate a scan experience, having a positive impact on patient satisfaction and anxiety. The aim was to obtain the views of practitioners on the use and implementation of such a tool in practice. METHODS A mixed methods study was conducted looking at the use of a virtual scan experience for patients prior to MRI. Nine radiographers attended two focus group sessions to see the tool and undergo a virtual experience. Following this, a survey based on the technology acceptance model was completed along with a semi-structured discussion about its use. RESULTS Perceived usefulness, ease of use, attitude and intention to use were all positive towards the virtual scan tool. All practitioners saw value in such a tool and how it could be implemented within practice, highlighting areas for improvement and development. CONCLUSION The practitioner's perspective was that access to such a virtual scan experience could be of use to better prepare and support those patients needing extra support before a real scan. Acknowledgement of having time to discuss patient concerns was noted and this could provide a means of doing so away from busy scanning lists whilst not taking up additional time. IMPLICATIONS FOR PRACTICE Use of VR tools could be a conduit through which trust and rapport are built in advance away from busy scanning lists, thereby not impacting on operational throughput and hindering efficiency.

Abstract
This study aimed to compare the effectiveness of virtual reality (VR) simulation as a patient preparation method for Magnetic Resonance Imaging (MRI) examinations. A total of 138 participants were divided into VR and non-VR groups. The study found that anxiety levels were significantly different between the VR group before and during MRI exams (p<.001), but there was no significant difference in the non-VR group (p=.138). Noise, space, and strapping were moderately correlated with anxiety levels. The study suggests that VR could be an accessible pre-medical procedure option, improving patient experience, future treatment planning, and reducing costs associated with premature MRI exams.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) generates patient anxiety (PA) and, therefore, it is important to understand individual and contextual variables that may cause it. In study one, we explored those anxiety predictors. In study two, we examined the effect of the experience of MRI on PA comparing anxiety pre- to post-MRI. METHODS PA was measured with an anxiety and stress scale in an interview format. Data collection occurred at a public hospital with MRI outpatients aged 18 or older. In study one (n = 204), participants answered the questionnaire immediately after experiencing the MRI and the data were analyzed through structural equation modeling. In study two (n = 242), participants answered the questionnaire before and after the examination and the data were analyzed through Bayesian statistics. RESULTS Being female, having a higher education level (EL), and not receiving information about the examination predicts higher PA after MRI. Patients with prior information have a decrease in PA from pre- to post-MRI. Those who do not have no change in PA. In low-educated patients, PA also decreases and no changes occur in highly educated patients. CONCLUSION This study provides health professionals with valuable indicators about patients who are more likely to perceive and express anxiety during MRI.

Abstract
INTRODUCTION This study investigated whether a 360° virtual counselling environment (360°VCE) was more effective at decreasing patients' anxiety than routine standard of care counselling for patients undergoing coronary computed tomography angiography (CCTA), and if there was any difference in the process times for both of these groups. METHODS A total of 86 patients underwent CCTA in this randomised controlled trial. Patients were randomly assigned to intervention and control groups. The 360°VCE was developed using spherical panoramic images and non-immersive 360° technology. The primary outcome, anxiety, was measured using the State-Trait Anxiety Inventory (STAI). The secondary outcome, CCTA process time, was measured from the time of arrival in the department until end of examination. RESULTS Pre-scan anxiety was lower among patients in the 360°VCE group immediately before CCTA in comparison to patients in the control group (p = 0.015). Women demonstrated higher levels of anxiety than men in both groups. No between-group differences were discerned in CCTA process time. CONCLUSION Access to 360°VCE can reduce patients' pre-CCTA anxiety levels. IMPLICATIONS FOR PRACTICE The presented results can be used to improve patient counselling and care, reduce anxiety among patients undergoing CCTA, and optimise the CCTA examination procedure.

Abstract
Background While magnetic resonance imaging (MRI) is one of the most efficient diagnostic methods used today, some patients may find an MRI examination to be a frightening experience. The proximity to the machine during screening and being in a confined space can cause a feeling of claustrophobia. Severe anxiety during MRI screening can cause the patient to move, which lowers the quality of the imaging and diagnostic test, and can result in the early termination of the MRI examination and the patient declining further testing. Objectives The objective of this study is to evaluate MRI examination-associated anxiety among Saudi Arabia's general population in the western region of the country. Methods Altogether, 465 participants who had undergone an MRI examination in the western region of Saudi Arabia were recruited for this cross-sectional study. We used the Magnetic Resonance Imaging-Anxiety Questionnaire (MRI-AQ) to collect data. Results Regarding anxiety symptoms, 82.8% of the participants believed that they had control over the event, 80.2% were concerned beforehand, 74% required more specific information, just 48% had difficulty breathing, and 51% were panicked. On the other hand, 57.4% felt safe, 56.8% were calm, and 49.2% were relaxed. The majority of the participants (55.9%, 260) reported moderate MRI-related anxiety. Conclusion More than half of our respondents had mild to moderate MRI-related anxiety. The majority needed more detailed information, panicked, and had breathing problems. Statistically, females showed a significantly higher level of anxiety compared with male participants.

Abstract
INTRODUCTION Magnetic Resonance Imaging remains an anxious experience for many, often exhibiting as fear of enclosed spaces. A useful metric to assess its prevalence and impact in practice is premature termination due to claustrophobia. Incidence varies and depends on many factors such as the physical nature of the imaging equipment and examination being undertaken, as well as the patient themselves. METHODS Scan appointment data from between April 2019-March 2021 was extracted and reviewed. Analysis included the type of scanner used, patient age, sex, examination area, funding source, attendance and completion status. Binomial logistic regression was performed to look for any relevant predictors of failure to scan due to claustrophobia. RESULTS Overall incidence of incomplete examinations due to claustrophobia was 0.76%. Whilst the majority of scans were performed on conventional systems, those undergoing Open scans were over three times more likely to fail a scan due to claustrophobia, whilst those undergoing UpRight scanning were half as likely. Likelihood of claustrophobia increases with females, those between 45-64years of age, funded by the NHS and entering the scanner head first or having a head scan. CONCLUSION Incidence of incomplete scanning is below 1% but with the potential for further reduction with implementation and use of improved scanner design and technology. Understanding the impact of other variables is also useful to raise awareness of those at greater risk of claustrophobia. However, there are wider influences beyond data alone to consider and account for. IMPLICATIONS FOR PRACTICE Whilst occurrence of claustrophobia is low, there remains a cost impact, as well as an importance in understanding the patient experience. Drawing on operational data can help provide a limited, generalised view to support service improvement.

Abstract
A method for the continuous detection of heart rate (HR) in signals acquired from patients using a sensor mat comprising a nine-element array of fiber Bragg gratings during routine magnetic resonance imaging (MRI) procedures is proposed. The method is based on a deep learning neural network model, which learned from signals acquired from 153 MRI patients. In addition, signals from 343 MRI patients were used for result verification. The proposed method provides automatic continuous extraction of HR with the root mean square error of 2.67 bpm, and the limits of agreement were -4.98-5.45 bpm relative to the reference HR.

This results in significant costs and delays to healthcare service provision due to appointment cancellations or patients' inability to complete MRI examinations. Radiographers may use several strategies to effectively manage patients with claustrophobia during MRI. This study aimed to determine radiographer's confidence in managing patients with claustrophobia and evaluate the perceived effectiveness of the intervention approaches employed. METHODS With institutional ethical approval, an online survey was conducted (15th September to 9th November 2020) among Kuwaiti MRI radiographers. The survey was designed to obtain information relating to participant demographics and the perceived confidence of radiographers in their use of interventions to manage claustrophobia during MRI procedures. Data obtained were analysed using the Statistical Package for the Social Sciences (v.26). RESULTS A total of 144 valid responses were obtained. Of the respondents, 82% (n = 118) were confident that they could support claustrophobic patients during MRI examinations. Almost all respondents (97.9%, n = 141) employed various claustrophobia reduction and relaxation techniques to improve patient experience and increase scan completion rates. There was a significant association between radiographer's level of education (rs = +0.18, p = 0.028) and experience (rs = +0.33, p < 0.001) with their confidence managing claustrophobic patients. While participating radiographers considered lectures and training the most effective methods to improve their skills in managing such patients, educating claustrophobic patients prior to their MRI scan was the most effective technique for facilitating scan completion. CONCLUSION Kuwaiti MRI radiographers are confident in applying different claustrophobic management techniques to improve patient compliance. Patient education, through supportive discussion, prior to their MRI examination was identified as the most effective intervention for managing claustrophobia. IMPLICATIONS FOR PRACTICE Patient education before MRI examination is necessary to enhance their experience and optimise scan completion rates. In addition, it is essential that MR radiographers develop their practical competence in supporting patients with claustrophobia during their scans.
