'Virtual experience' as an intervention before a positron emission tomography/CT scan may ease patients' anxiety and improve image quality.

INTRODUCTION: The aim of our study was to investigate the effect of a 'virtual experience' on reducing people's anxiety levels and improving image quality. METHODS: This study included 200 people who underwent 18 F-FDG PET/CT scan for the first time. Healthy people (n = 100) and patients (n = 100) were randomly divided into a control group and an intervention group. In the intervention group, we used a 'virtual experience' as an intervention before the scan. We used the Spielberger State-Trait Anxiety Inventory (STAI) and satisfaction questionnaires for evaluation. Additionally, the image quality was analysed. RESULTS: In the control group, more patients presented anxiety than healthy people (26(52%) versus 15(30%)) (P = 0.041). However, when the 'virtual experience' was provided, the number of cases of anxiety in the patient group decreased to 19(38%). Furthermore, patients in the intervention group had lower STAI-related scores than those in the control group (STAI-S: 37.08 ± 9.42 versus 43.34 ± 10.49, P = 0.109; STAI-T: 36.24 ± 9.55 versus 40.72 ± 9.00, P = 0.019). With respect to image quality, people who had higher STAI-related scores were more likely to have unqualified images. CONCLUSION: A 'virtual experience' provided by an audio-visual installation can ease patients' anxiety and improve image quality.

Cancer Patient Experience in a Nuclear Medicine Department: Comparison Between Bone Scintigraphy and 18F-FDG PET/CT.

Our objective was to assess the anxiety level in cancer patients undergoing nuclear medicine exams and to identify how professionals can improve patient experience. Methods: In total, 94 patients undergoing 99mTc-hydroxymethylene diphosphonate (99mTc-HDP) bone scintigraphy (BS) or 18F-FDG PET/CT completed 2 scan-experience questionnaires and the Spielberger State Anxiety Inventory (STAI-S) before the scan and after image acquisition. Results: Before the exam, the mean anxiety levels were higher for the 99mTc-HDP BS group than for the 18F-FDG PET/CT group. After the exam, the opposite was true. Both groups experienced a reduction in anxiety after the scan (prescan score, 51.75 for 99mTc-HDP BS and 44.67 for 18F-FDG PET/CT; postscan score, 36.70 for 99mTc-HDP BS and 38.82 for 18F-FDG PET/CT). The greatest anxiety factor for the 99mTc-HDP BS group was the duration of the exam (mean ± SD, 5.34 ± 2.08), whereas for the 18F-FDG PET/CT group it was the result (5.40 ± 1.80). Conclusion: Patients undergoing nuclear medicine exams in an oncologic context had significant anxiety levels before and after their scans. However, 99mTc-HDP BS and 18F-FDG PET/CT had different triggers. It is of extreme importance that health-care professionals be aware of these peculiarities and adjust their procedures accordingly.

Research Use of Ecological Momentary Assessment for Adverse Event Monitoring Following Amyloid-ß Results Disclosure.

As calls for transparency in human subjects research grow, investigators conducting Alzheimer's disease (AD) biomarker research are increasingly required to consider their ethical obligations regarding the return of AD biomarker test results to research participants. When disclosing these test results to potentially vulnerable participants, investigators may face unique challenges to identify adverse events, particularly psychological events. The purpose of this paper is to describe our research team's experience with developing and implementing a process for enhanced adverse event monitoring following the return of amyloid-ß (Aß) imaging results to research participants with mild cognitive impairment (MCI). Ethical and logistical considerations are presented along with preliminary findings from an ongoing randomized controlled trial of Aß imaging results disclosure in MCI. Following receipt of amyloid imaging results, participants underwent 14 days of adverse event monitoring using ecological momentary assessment (EMA), a strategy to capture health, behaviors, and mood as they occur in participants' natural settings in real time. EMA telephone calls were placed at random during waking hours to screen for mood changes. Investigators were alerted for positive depression, anxiety, suicidal ideation screenings, or for two days of failed call attempts. Preliminary feasibility of twenty-four participants with MCI who participated in EMA mood assessments was successfully completed 83% (SD = 0.4) of the time over 14 days with no alerts for anxiety or depression screening items. EMA, when used with standard adverse event monitoring, is a promising and novel approach to maximize early detection of negative psychological reactions following AD biomarker results disclosed in research settings.

Randomized Controlled Trial Examining Effects of Web-Based Information on Patient Satisfaction and Image Quality in 18F-FDG PET/CT Examinations.

Our aim was to compare the effect that having access, versus not having access, to web-based patient information on 18F-FDG PET/CT has on image quality and on patient satisfaction with their care during and knowledge about the examination, as well as to explore whether patients utilized and were satisfied with the web-based information. Methods: We recruited 148 patients between October 2015 and December 2016 and randomly assigned them to a standard-care group or an intervention group. Both groups received standard information about the 18F-FDG PET/CT examination, but the intervention group also received access to web-based information. A questionnaire was used to evaluate patient satisfaction with, knowledge about, and discomfort during the examination, and a masked assessment of image quality was conducted. Results: Overall satisfaction was high in both groups. The lowest satisfaction was with information about how the patients would receive the results of the examination. More patients in the intervention group than in the standard-care group knew how the 18F-FDG PET/CT examination would be conducted. Descriptive data suggest that image quality was slightly better in the intervention group than in the standard-care group, but none of the outcomes significantly differed between the groups. However, several obstacles were encountered during recruitment that led to insufficient power to detect differences. Also, only 54 of 75 patients (72%) in the intervention group utilized the web-based information. However, those who did utilize the information were satisfied with it and found it helpful. Conclusion: The effects of web-based information need to be investigated in a larger sample of patients. Having access to improved information before undergoing 18F-FDG PET/CT may help patients prepare for and undergo the examination. It may also improve image quality. However, this possibility needs to be investigated using image quality as the primary outcome. The results may be used to improve patient information and care and thereby optimize the 18F-FDG PET/CT procedure.

Patient perspectives on repeated MRI and PET/CT examinations during neoadjuvant treatment of esophageal cancer.

OBJECTIVE: The perceived burden of diagnostic tests by patients during the assessment of esophageal cancer warrants attention with the current increase in repeated imaging for purposes of disease monitoring during and after treatment. The purpose of this prospective study was to evaluate the experienced burden associated with repeated MRI and positron emission tomography with integrated CT (PET/CT) examinations during neoadjuvant treatment for esophageal cancer from the perspective of the patient. METHODS: In 27 patients receiving neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer MRI and PET/CT examinations were performed before nCRT, during nCRT and before surgery. The experienced burden during repeated MRI and PET/CT examinations was evaluated with a self-report questionnaire addressing discomfort, pain, anxiety and embarrassment, each measured on a 5-point Likert scale (1 = none; up to 5 = very much). In addition, a comparative assessment was used to rank MRI, PET/CT and baseline endoscopy. RESULTS: All scans were performed without the occurrence of an adverse event. Few patients experienced discomfort (mean score ±SD: 1.9 ± 1.0 for MRI vs 2.0 ± 1.0 for PET/CT, p = 0.586), pain (1.1 ± 0.4 for MRI vs 1.3 ± 0.7 for PET/CT, p = 0.059), anxiety (1.0 ± 0.2 for MRI vs 1.0 ± 0.2 for PET/CT, p = 1.000) and embarrassment (1.0 ± 0 for MRI vs 1.0 ± 0.2 for PET/CT, p = 0.317) during both MRI and PET/CT. Patients preferred MRI over PET/CT (67% vs 22%, respectively, p = 0.023), and MRI over endoscopy (59% vs 19%, respectively, p = 0.027). In the comparison between PET/CT and endoscopy, 59% of patients preferred PET/CT and 26% preferred endoscopy (p = 0.093). CONCLUSION: Repeated imaging with both MRI and PET/CT is generally well-tolerated for the assessment of response to treatment in esophageal cancer patients. Shorter acquisition times and altered body positioning during scanning will likely improve patient experience. Advances in knowledge: This paper demonstrates that MRI and PET/CT are generally well-tolerated imaging procedures for the assessment of response to treatment in esophageal cancer patients. When asked to rank different tests, patients preferred MRI over PET/CT and endoscopy.

Perceived patient burden and acceptability of whole body MRI for staging lung and colorectal cancer; comparison with standard staging investigations.

OBJECTIVE: To evaluate perceived patient burden and acceptability of whole body MRI (WB-MRI) compared to standard staging investigations, and identify predictors of reduced tolerance. METHODS: Patients recruited to multicentre trials comparing WB-MRI with standard staging scans for lung and colorectal cancer were invited to complete two questionnaires: a baseline questionnaire at recruitment, measuring demographics, comorbidities, and distress; and a follow-up questionnaire after staging, measuring recovery time, comparative acceptability/satisfaction between WB-MRI and CT (colorectal cancer) and PET-CT (lung cancer), and perceived scan burden (scored 1, low; 7, high).  Results: 115 patients (median age 66.3 years; 67 males) completed follow up and 103 baseline questionnaires. 69 (63.9%) reported "immediate" recovery from WB-MRI and 73 (65.2%) judged it "very acceptable". Perceived WB-MRI burden was greater than for CT (p < 0.001) and PET-CT (p < 0.001). High distress and comorbidities were associated with greater WB-MRI burden in adjusted analyses, with deprivation only approaching significance (adjusted regression ß = 0.223, p = 0.025; ß = 0.191, p = 0.048; ß = -0.186, p = 0.059 respectively). Age (p = 0.535), gender (p = 0.389), ethnicity (p = 0.081) and cancer type (p = 0.201) were not predictive of WB-MRI burden. CONCLUSION:  WB-MRI is marginally less acceptable and more burdensome than standard scans, particularly for patients with pre-existing distress and comorbidities.  Advances in knowledge: This research shows that WB-MRI scan burden, although low, is higher than for current staging modalities among patients with suspected colorectal or lung cancer. Psychological and physical comorbidities adversely impact on patient experience of WB-MRI. Patients with high distress or comorbid illness may need additional support to undergo a WB-MRI.

It's a question of endurance - Patients with head and neck cancer experiences of 18F-FDG PET/CT in a fixation mask.

PURPOSE: This study aimed to explore how patients with head and neck cancer experienced undergoing an 18F-fluoro-deoxy-glucose positrons emissions tomography/computed tomography (18F-FDG PET/CT) examination in a fixation mask. METHOD: Interviews were conducted with nine patients with known or suspected head and neck cancer who were scheduled for the examination for the first time. The phenomenological method according to van Manen and his four lifeworld existentials; lived space, lived body, lived time, and lived relation was used to analyse the interviews. RESULTS: The thoughts and feelings of the patients during the PET/CT examination varied, some found it very difficult, while others did not. However, for all the patients, it was an experience that required some form of coping to maintain composure for example distraction. CONCLUSIONS: PET/CT examnation in a fixation mask may be strenuous for some patients. Patients need more detailed information, including suggestions for coping behaviours, prior to the examination, as well as higher level of support during and after the examination. The results of this study may be used to improve patient care and optimize the procedure of PET/CT examination in a fixation mask.

Assessment of Whether Patients' Knowledge, Satisfaction, and Experience Regarding Their 18F-Fluoride PET/CT Examination Affects Image Quality.

UNLABELLED: The aim of this study was to investigate patients' previous knowledge, satisfaction, and experience regarding an (18)F-fluoride PET/CT examination and to explore whether any discomfort or pain during the examination was associated with reduced image quality. A further aim was to explore whether patients' health-related quality of life (HRQoL) was associated with their satisfaction and experience regarding the examination. METHODS: Between November 2011 and April 2013, 50 consecutive patients with a histopathologic diagnosis of prostate cancer who were scheduled for (18)F-fluoride PET/CT were asked to participate in the study. A questionnaire was used to collect information on the patients' previous knowledge and experience regarding the examination. Image quality was assessed according to an arbitrary scale. The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and the prostate cancer-specific module (QLQ-PR25) were used to assess HRQoL. RESULTS: Forty-six patients (96%) completed the questionnaire. Twenty-six percent did not at all know what a (18)F-fluoride PET/CT examination was. Most (52%-70%) were satisfied to a very high degree with the care provided by the nursing staff but were less satisfied with the information given before the examination. Image quality was similar between patients who were exhausted or claustrophobic during the examination and those who were not. No correlations between HRQoL and the patients' experience regarding (18)F-fluoride PET/CT were found. CONCLUSION: Most patients were satisfied with the care provided by the nursing staff, but there is still room for improvement, especially regarding the information provided before the examination. A long examination time may be strenuous for the patient, but there was no difference in image quality between patients who felt discomfort or pain during the examination and those who did not.
