Investigating a Technologist-Driven Injection Technique in Lymphoscintigraphy at a Single Rural Center: A Retrospective Audit.

Our aim was to investigate the effectiveness of the technologist-driven injection technique of lymphoscintigraphy used at a rural hospital in Australia to identify the correct lymph node for sentinel lymph node biopsy (SLNB) in early-stage breast cancer patients. Methods: A retrospective audit was conducted using imaging and medical record data from 145 eligible patients who underwent preoperative lymphoscintigraphy for SLNB at a single center throughout 2013 and 2014. The lymphoscintigraphy technique included a single periareolar injection with subsequent dynamic and static images as required. Descriptive statistics, sentinel node identification rates, and imaging-surgery concordance rates were generated from the data. Additionally, χ2 analysis was used to examine the relationships between age, previous surgical intervention, and injection site and time until a sentinel node is visualized. The technique and statistical results were directly compared against multiple similar studies in the literature. Results: The sentinel node identification rate was 99.3%, and the imaging-surgery concordance rate was 97.2%. The identification rate was significantly higher than those of similar studies in the literature, and concordance rates were similar across studies. The findings demonstrated that age (P = 0.508) and previous surgical intervention (P = 0.966) did not influence the time it takes to visualize a sentinel node. Injection site did appear to have a statistically significant effect (P = 0.001), with injections in the upper outer quadrant correlating with increased times between injection and visualization. Conclusion: The reported lymphoscintigraphy technique for identifying sentinel lymph nodes for SLNB in early-stage breast cancer patients can be justified as an accurate and effective method that is time-sensitive and has outcomes comparable to those of successful studies in the literature.

Systemic disregard, demoralising occupational burnout, protective maturity: The 'lived' experience of nuclear medicine technologists and the impact of COVID-19.

OBJECTIVE: It has been shown that stress in the workplace can contribute to the development or worsening of mental health conditions, as well as having a negative impact on personal relationships and life outside of work. Therefore, prolonged job stress can be damaging to an individual's mental health and wellbeing, potentially leading to burnout. There is limited research surrounding the wellbeing of nuclear medicine technologists practicing globally, and more specifically in Australia. This interpretative phenomenological study seeks the lived experience of nuclear medicine technologists within a large metropolitan city in Australia, how these experiences and COVID-19 has impacted their wellbeing. METHODS: Five participants were recruited who had greater than five years working experience as a nuclear medicine technologist. Data was collected using semi-structured interviews conducted online via Zoom to accommodate COVID-19 restrictions. The data was transcribed and analysed according to interpretative phenomenological analysis (IPA) protocols. RESULTS: One superordinate theme: systemic regard, demoralizing burnout, protective maturity, overarched four subordinate themes: staying physically and psychologically safe; risk of burnout; maturity as protective against burnout; and COVID-19 drain. Pressures both prior to and during COVID-19 leave the participants feeling undervalued, discredited, and at risk of burnout. However, maturity brings confidence to incorporate their strengths in a more holistic view of life. Glimmers of positivity come from choices to alter their career path and the unexpected opportunities to spend time with family through COVID-19 restrictions. DISCUSSION: Overall, the participants of this study expressed a lack of positivity about their own individual experiences within their career. Occupational stress, caused by workplace bullying, increased workload and understaffing increased their risk of burnout. Although as the participants matured, their ability to cope with occupational stressors improved. The recent COVID-19 pandemic exacerbated the participants' risk of burnout. CONCLUSION: Due to a number of contributing workplace factors, exacerbated by the unexpected COVID-19 pandemic, participants in this study appeared to have an increased risk of developing burnout. However, maturity and life experience has helped mitigate this risk.

Agreement Between Dual-Energy X-ray Absorptiometry and Bioelectric Impedance Analysis for Assessing Body Composition in Athletes: A Systematic Review and Meta-Analysis.

OBJECTIVE: To compare dual-energy x-ray absorptiometry (DXA) and bioelectric impedance analysis (BIA) in the assessment of body composition in athletes. DATA SOURCES: A systematic review and meta-analysis was conducted collating peer-reviewed studies that compared BIA with DXA for the assessment of body composition in athletes that indexed in MEDLINE, CINAHL, EMBASE, and PsycINFO databases. MAIN RESULTS: After duplicate removal, 267 articles remained for full-text screening. Sixty-three studies remained for the final inclusion, with 8 focused on athletes (n = 461). Five studies were included in the meta-analysis and were rated as positive after risk of bias assessment, whereas the remaining were neutral. BIA overestimated fat-free mass (FFM) over DXA 2.78 (1.38-4.18) (mean difference ± 95% CI) with an effect size of 3.9( P < 0.001). CONCLUSIONS: BIA was found to overestimate total FFM when compared with DXA. Correlations are high between BIA and DXA; however, the limits of agreement are wide. Hence, BIA may not be a suitable substitute for DXA body composition scanning of athletes. Because of the low level of ionizing radiation exposure, the use of DXA should always be medically justified, and therefore, it is not recommended for repeat, longitudinal measurements in healthy subjects.We recommend that clinicians do not use BIA interchangeably with DXA in the assessment of body composition in athletes. Considerations should be made over the safety and appropriateness of DXA in young healthy adults. For long-term use, BIA can be warranted for athletes.PROSPERO Registration Number: CRD42020183777.

Health screening questionnaires used in the management of mental distress acquired during an injured worker's return to work: A scoping review.

BACKGROUND: Mental distress is often endured by injured workers participating in the rehabilitation or return to work process following a physical injury. Delays in detecting the onset and treating mental distress can lead to a diverse range of cognitive and behavioural changes that may precipitate psychological distress such as anxiety, depression, and posttraumatic stress. OBJECTIVE: The objective of this scoping review was to provide an overview of existing health questionnaires utilised by health care providers and affiliated researchers. It reviewed their effectiveness and suitability to detect mental distress endured by injured workers engaged in the return to work process. METHODS: A scoping review methodology was conducted using the Arksey and O'Malley framework which examined peer-reviewed articles published between 2000 and March 2020 comprising health questionnaires. Database searches included Medline, CINAHL, EMBASE and PsycINFO combining specific MeSH terms and key words. RESULTS: The full search identified 3168 articles. Following full screening a total of 164 articles reviewed the use of health questionnaires and specific criteria to determine their suitability. Most of the health questionnaires reviewed were used as screening measures for identifying both work and non-work-related psychological hazards. However, they were found to be limited in their application when considering all potential predictors of delayed return to work such as poor or stressful interactions with stakeholders, financial stress and the injured workers experience of the RTW process. CONCLUSION: Earlier identification of mental distress using an optimal MHSQ followed by appropriate intervention will reduce the risk of psychological injury becoming cumulative on a physical workplace injury. Without such complications, early return to work can be achieved with significant cost saving to the economy.

Relationship between Posture and Non-Contact Lower Limb Injury in Young Male Amateur Football Players: A Prospective Cohort Study.

Posture, a potentially modifiable injury risk factor, is considered important in injury screening/prevention in athletes, yet few studies investigate relationships between posture and injury. This prospective cohort study investigated whether static posture is associated with lower limb injury risk in male football players (n = 263). Nine aspects of static standing posture (left and right rearfoot, knee interspace, lateral knee, lumbar lordosis, thoracic kyphosis, scoliosis S and C, forward head) were assessed from photographs during the pre-season using the modified Watson and Mac Donncha scale, which was dichotomised for analysis (deviated or normal). Player characteristics (age, height, mass, body mass index, competition level), match/training exposure, and previous and in-season non-contact lower limb injuries were recorded. Binary logistic regression investigated relationships between posture and injury (previous and in-season). Eighty previous and 24 in-season lower limb injuries were recorded. Previous injury was not associated with any postural variable. In-season injury was associated with previous injury (OR = 3.04, 95% CI 1.20-7.68, p = 0.02) and having a normal thoracic curve compared to kyphosis (OR = 0.38, 95% CI 0.15-1.00, p = 0.05) but no other postural variables. Static postural deviations observed in male football players in the pre-season are not typically associated with non-contact lower limb injury risk; thus, they are unlikely to add value to pre-season screening programs.

Burnout in the disciplines of medical radiation science: A systematic review.

OBJECTIVE: Burnout is seen as an occupational phenomenon related to workplace stress. Professional groups within medical imaging and radiation science have been reported to suffer from burnout in the past, however research into the profession has been limited. This systematic review aims to evaluate literature measuring levels and prevalence of burnout in the professional groups within medical imaging and radiation science (MIRS). These being radiographers (radiological technologists), sonographers, radiation therapists (therapeutic radiographers) and nuclear medicine technologists. METHODS: Electronic databases including Medline, Embase, Psycinfo and CINAHL were searched to locate studies published in English from 2000 that used a questionnaire/survey to measure burnout in the MIRS population. Also included were studies that measured burnout in a larger healthcare group that included MIRS professionals, as long as the MIRS professionals were reported as a separate group. RESULTS: Sixteen articles met the inclusion criteria; two of these articles reported the same data and therefore were combined to leave 15 studies to review. Of the radiation therapy group, seven of the nine studies reported low or moderate burnout amongst their participants. One study reported high levels of burnout in the emotional exhaustion and depersonalisation domains, and another reported high emotional exhaustion levels. Within the other MIRS professions, five of the six studies reported moderate burnout. One group of sonographers had high levels of burnout in the emotional exhaustion domain. CONCLUSION: For the past 20 years, levels of burnout in MIRS professionals has remained relatively steady, with the majority of studies reporting moderate levels of burnout. However, more research is needed in radiographers, sonographers and nuclear medicine technologists. IMPLICATIONS FOR PRACTICE: Even though the review indicates moderate level of burnout, this needs addressing on an organisational and individual level to ensure stress in the workplace is managed before burnout becomes a significant issue.

Health and Lifestyle Factors of Australian Medical Radiation Workers: A Pilot Study Using Nuclear Medicine Technologists.

The health effects of chronic low-dose radiation exposure are a subject of worldwide debate. These effects are difficult to assess because all low-dose exposure mechanisms must be accounted for, including background exposure, personal medical examinations, and environmental exposure such as aviation, as well as lifestyle choices contributing to disease. The current literature recommends investigation of lifestyle factors to fill in these gaps. The aim of this study was to pilot-test a survey developed to assess health and lifestyle factors for Australian medical radiation workers. Methods: A cohort of nuclear medicine technologists (NMTs) was selected to test the survey. The survey consisted of 53 questions relating to demographics, employment, lifestyle, and health. Data from the 2017-2018 Australian National Health Survey were used to compare the lifestyle choices and health of the participants with those of the Australian general population. Results: In total, 101 participants pilot-tested the survey. Overall, Australian NMTs make better lifestyle choices (more exercise, more vegetable intake, lower rates of smoking and alcohol consumption) resulting in lower rates of obesity than the Australian general population. NMTs had a higher reported health status than the Australian population, with lower levels of psychologic distress. Given the low age of NMTs participating in the study, the cancer incidence rate may be higher than that reported for the Australian general population; however, a larger sample size is required to provide more definitive results. Conclusion: This pilot study demonstrated the feasibility of conducting a widespread survey to assess health and lifestyle factors for the Australian medical radiation worker cohort. Comparison of survey results with data for the entire Australian population have highlighted the potential to increase the number of lifestyle questions.

Exploring the evidence-practice gap in the use of plain radiography for acute abdominal pain and intestinal obstruction: a systematic review and meta-analysis.

AIM: Previous studies, some dating back several decades, have recommended that the use of plain abdominal radiography should be curbed, particularly with the growth of more accurate imaging modalities. However, evidence from referral data suggests that plain abdominal radiography continues to be a commonly requested examination. The aim of this review was to explore the gap between evidence and practice by re-examining the evidence using a robust methodology, investigating the diagnostic accuracy of plain abdominal radiography. METHODS: Studies were identified from electronic databases and reference lists. Eligible studies provided data as to the sensitivity and specificity of plain abdominal radiography for either acute abdominal pain (Group A) or suspected intestinal obstruction (Group B). Version 2 of the Quality Assessment of Diagnostic Accuracy Studies was used to assess the quality of studies and hierarchical summary receiver operator characteristic curves and coupled forest plots were generated. RESULTS: Four studies evaluated plain abdominal radiography for acute abdominal pain (Group A) and 10 for suspected intestinal obstruction (Group B). Two studies investigated both presentations and were included in both groups. Methodological quality of studies was moderately high, though incorporation bias was a common limitation. Sensitivity for Group A studies ranged from 30 to 46%, with specificity from 75 to 88%. For Group B, the range of sensitivity was 48 to 96% and specificity from 50 to 100%. CONCLUSION: The results suggest that use of plain abdominal radiography could be substantially reduced, particularly for patients with undifferentiated acute abdominal pain. While some guidelines exist, there is sound argument for clinical decision rules for abdominal imaging to inform evidence-based clinical decision-making and radiology referrals.

Musculoskeletal discomfort and use of computers in the university environment.

This cross-sectional study investigated musculoskeletal discomfort and computer use in university staff, through the use of online questionnaires. Results showed a high prevalence of staff reported musculoskeletal discomfort during the preceding year (80%), with neck (60%), shoulder (53%) and lower back discomfort (47%) being the most common. Most believed discomfort was caused by work, although neck discomfort was significantly less in those reporting excellent mental health (OR 0.44, p < 0.01). Computer navigation was performed primarily by mouse (77%); however, using a touch pad increased the odds (OR 1.17, p < 0.01) of wrist discomfort and the belief it was caused by work (OR 1.19, p < 0.01). Few staff attended ergonomic training (16%) or requested workstation assessments (26%). However, high rates of staff reporting musculoskeletal discomfort sought professional treatment (range: 35.2% wrist/hand to 65.0% shoulder). Strategies are needed to address uptake of preventive measures and reduce reliance on medical treatments following musculoskeletal discomfort in universities.

Research methods for formal consensus development.

AIM: This paper reviews three research methods for developing consensus. BACKGROUND: Consensus statements and guidelines are increasingly used to clarify and standardise practice, and inform health policy, when relevant and rigorous evidence is lacking. Clinicians need to evaluate the quality of practice guidelines to determine whether to incorporate them into clinical practice or reject them. Formal methods of developing consensus provide a scientific method that uses expert panel members to evaluate current evidence and expert opinions to produce consensus statements for clinical problems. DATA SOURCES: Online search for relevant literature was conducted in Medline and CINAHL. REVIEW METHODS: A literature review of consensus, consensus development and research methods papers published in English in peer-reviewed journals. DISCUSSION: The three methods of developing consensus discussed are the Delphi technique, nominal group technique and the consensus development conference. The techniques and their respective advantages are described, and examples from the literature are provided. The three methods are compared and a flowchart to assist researchers selecting an appropriate method is included. Online resources with information on the development and evaluation of clinical guidelines are reviewed. CONCLUSION: This paper will help researchers to select an appropriate research method for developing consensus statements and guidelines. IMPLICATIONS FOR RESEARCH/PRACTICE: When developing consensus guidelines for clinical practice, researchers should use a formal research method to ensure rigour and credibility.

Development of consensus statements for pregnancy screening in diagnostic nuclear medicine: a Delphi study.

UNLABELLED: Current radiation protection recommendations do not provide clear guidelines or advice on pregnancy screening strategies for diagnostic nuclear medicine procedures. Previous studies have reported on variations in current practice for pregnancy screening before diagnostic nuclear medicine procedures. The development of consensus statements aims to provide a consistent approach and assist nuclear medicine personnel to confidently question patients about their pregnancy status. METHODS: The Delphi technique was chosen for the research design. A panel consisting of 10 experienced nuclear medicine personnel from Australia and New Zealand was recruited. Panel members were provided with a summary of existing research. Consensus agreement was predefined as 80%. Questionnaires were developed and distributed to the panel members, with iterative analysis and feedback between survey rounds. Three survey rounds were conducted online using SurveyMonkey between December 2013 and June 2014. The round 1 questionnaire was developed from the results of a previous survey. It consisted of 30 questions designed to gather the opinions of the expert panel. After analysis of the round 1 responses, consensus statements were developed for round 2 and revised in round 3. RESULTS: Consensus was achieved for 16 statements. The statements recommend using verbal questioning with patient signature, defining the age range for questioning as 12-55 y, providing advice on the use of pregnancy testing, and questioning potentially difficult groups such as teenagers. A flowchart was included for comment in round 3. CONCLUSION: This was the first Australian study to develop consensus statements and a flowchart to assist nuclear medicine personnel in consistently and confidently questioning patients about their pregnancy status before diagnostic procedures. Implementation of these statements into clinical practice guidelines should reduce the possibility of inadvertent fetal irradiation.

Pregnancy screening strategies for potentially challenging patients before diagnostic nuclear medicine procedures: qualitative survey analysis.

UNLABELLED: Because of the ionizing radiation used in diagnostic nuclear medicine procedures, it is recommended that all female patients of childbearing age be questioned about their pregnancy status before the procedure begins. Several patient groups have been identified as potentially difficult to question: teenagers, unconscious or sedated patients, patients with language or cultural barriers, and patients with mental disability. Our aim was to capture the thoughts and opinions of nuclear medicine personnel in Australia and New Zealand regarding pregnancy screening strategies before diagnostic imaging procedures. METHODS: Members of the Australian and New Zealand Society of Nuclear Medicine were invited to complete an online survey. Section 4 consisted of open-response questions asking participants to describe the strategies they use to question a patient about pregnancy status in 4 potentially difficult clinical scenarios. The content of the responses was analyzed. RESULTS: For each question, 232 responses were recorded. The most commonly used strategies included questioning teenage girls away from their parents, referring to medical notes for unconscious patients, using an interpreter and visual aids for patients with language barriers, and asking a caregiver or relative of mentally disabled patients. Pregnancy testing was used when there was doubt about the patient's pregnancy status. Personal questions about menstrual and sexual history were often asked to determine the risk of pregnancy. CONCLUSION: The study revealed that a variety of strategies are used by nuclear medicine personnel in Australia and New Zealand to determine the pregnancy status of patients. A standardized practice guideline may be useful to ensure a consistent approach to questioning that would optimize the accuracy of pregnancy assessment and reduce the possibility of fetal irradiation.

Pregnancy screening strategies for diagnostic nuclear medicine: survey results from Australia and New Zealand.

UNLABELLED: The ionizing radiation used in diagnostic nuclear medicine procedures has the potential to cause biologic harm to a fetus. Although the risks are relatively small, it is recommended that all female patients of childbearing age be questioned regarding their pregnancy status before administration of the radiopharmaceutical. This can be a sensitive situation especially for certain types of patients, such as teenagers. Currently, there are no guidelines that detail how to question the patient. Previous studies have revealed the lack of a consistent approach in this area. The aim of this study was to investigate current practice for pregnancy screening before diagnostic nuclear medicine procedures in Australia and New Zealand and to determine whether a standardized practice guideline is required. METHODS: An online survey was administered via SurveyMonkey from October to December 2011. Members of the Australian and New Zealand Society of Nuclear Medicine were invited to participate. The survey consisted of 30 questions divided into 4 sections: demographics, policy and regulations, current practice, and open-ended clinical scenarios. RESULTS: Three hundred thirty-five responses were recorded from participants in all states and territories of Australia and New Zealand; 90% were nuclear medicine technologists. Participants reported a low awareness of radiation policy and regulations but demonstrated good knowledge of the relative risk to the fetus from commonly performed procedures. The most common minimum and maximum age to question patients was 12 y (32%) and 55 y (42%), respectively, although the range was from 10 to 60 y. Verbal questioning (44%) was the most commonly used approach. Pregnancy testing was used by 72%, usually if the patient indicated she was unsure of her pregnancy status. Responses to clinical scenarios were varied, and these will be discussed in a subsequent paper. CONCLUSION: The survey revealed a lack of awareness of government regulations and departmental policy regarding radiation protection. The study demonstrated wide variety in pregnancy screening strategies used to determine the pregnancy status of patients before diagnostic nuclear medicine procedures, indicating that a standardized practice guideline is required for Australia and New Zealand.

Determining the pregnancy status of patients before diagnostic nuclear medicine procedures: the Australian experience.

UNLABELLED: Ionizing radiation used in diagnostic nuclear medicine procedures has the potential to have biologic effects on a fetus. Nuclear medicine technologists (NMTs) therefore have a responsibility to ensure that they question all patients of childbearing age about their pregnancy status before starting any procedure, to avoid unnecessary fetal irradiation. In Australia, there are no clearly defined practice guidelines to assist NMTs in determining whom to question or how to question their patients. METHODS: Semistructured interviews were conducted with chief NMTs and staff NMTs in 8 nuclear medicine departments in Australia. Questions were based around 5 areas: regulations and policy, fetal radiation exposure, questioning of the patient, difficulties in determining pregnancy status, and the impact of the use of hybrid imaging. Audio files of the interviews were transcribed and coded. RESULTS: Topics were coded into 5 themes: policy and awareness of guidelines, questioning the patient, radiation knowledge, decisions and assumptions made by NMTs, and the use of pregnancy testing. There was a wide variation in practice between and within departments. NMTs demonstrated a lack of knowledge and awareness of the possible biologic effects of radiation. CONCLUSION: This study identified a need in Australia for nuclear medicine to arrive at a consensus approach to verifying a patient's pregnancy status so that NMTs can successfully question patients about their pregnancy status. Continuing education programs are also required to keep NMTs up to date in their knowledge.
