An evaluation of the experiences of radiography students working on the temporary HCPC register during the COVID-19 pandemic

IntroductionThe COVID-19 pandemic has changed the world's perspective and had a profound impact on all those residing in the United Kingdom, resulting in unprecedented changes being made to the education and training of healthcare students. Universities and practice partners had to respond quickly and work in close collaboration with their wider system partners, Health Education England and the Department of Health, to ensure the changes made within the Health and Care Professions Council (HCPC) emergency measures were implemented.The aim was to explore the experiences of final year diagnostic and therapeutic radiography students who joined the HCPC temporary register during phase one of the COVID-19 pandemic.MethodsThis study was informed by a phenomenological approach, in which a purposeful sample of seventeen participants comprising of nine students, six practice educators and two academics were chosen to participate. Semi-structured interviews and focus groups were conducted to collect the data via a virtual platform.ResultsThe results highlighted three themes, professionalism and transition to registration, benefits and challenges of working through a pandemic, and emotional impact. Students described how they gained confidence and competence during their time on the temporary register and suggested that professional bodies could consider curriculum changes to encompass a final transitional placement similar to their experience. They said they had been well supported but felt a sense of loss having been denied the normal rite of passage associated with completion of their course and graduation.ConclusionThe results provide insight into how students, practice educators and academics transformed their practice to meet the necessary requirements whilst working during the first phase of the COVID-19 pandemic. They highlight the importance of having good support mechanisms in place and the rewards and challenges for students joining their professional register early.Implications for practiceSome consideration could be made to changing the curriculum in the future to allow for early temporary registration and paid Band 4 final placements for students working as assistant practitioners.     

An evaluation of the experiences of academics and practice educators who supported radiography students working on the temporary HCPC register during the COVID-19 pandemic

IntroductionThe COVID-19 pandemic has had a profound impact on all those residing in the United Kingdom, resulting in unprecedented changes being made to the education and training of healthcare students. Universities and practice partners had to respond quickly and work in close collaboration with Health Education England, to ensure the changes brought in by the Health and Care Professions Council (HCPC) emergency measures were implemented.The aim of this study was to explore the experiences of staff supporting final year diagnostic and therapeutic radiography students who joined the HCPC register early during phase one of the COVID-19 pandemic.MethodsThis study was informed by a phenomenological approach, in which a purposeful sample of eight participants comprising of six practice educators (PEs) and two academics. Semi-structured interviews and focus groups were conducted to collect the data via a virtual platform.ResultsThe results highlighted three themes, Competence and the transition to registration, Support mechanisms and Communication. Both academics and PEs described how they observed the new registrants gaining confidence and competence during their time on the temporary register and suggested that professional bodies could consider curriculum changes to encompass a final transitional placement similar to their experience. They suggested that having robust support mechanisms and communication in place are essential for the success of this initiative.ConclusionThe results provide insight into how PEs and academics supported new registrants to meet the necessary requirements of the HCPC register whilst working during the first phase of the COVID-19 pandemic. They highlight the importance of having robust support mechanisms and good communication in place to achieve this.Implications for practiceSome consideration could be made to changing the curriculum in the future to allow for early temporary registration and paid Band 4 final placements for students working as assistant practitioners.     

A qualitative analysis of radiography students' reflective essays regarding their experience of clinical placement during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic significantly impacted healthcare services and clinical placement for healthcare students. There is a paucity of qualitative research into radiography students’ experiences of clinical placement during the pandemic.MethodStudents in stages three and four of a 4-year BSc Radiography degree in Ireland wrote reflective essays regarding their experience of clinical placement during the COVID-19 healthcare crisis. Permission was granted by 108 radiography students and recent graduates for their reflections to be analysed as part of this study. A thematic approach to data analysis was used, allowing themes to emerge from the reflective essays. Two researchers independently coded each reflective essay using the Braun and Clarke model.ResultsFour themes were highlighted; 1) Challenges associated with undertaking clinical placement during the pandemic, such as reduced patient throughput and PPE-related communication barriers; 2) Benefits of clinical placement during the pandemic, in terms of personal and professional development and completing degree requirements to graduate without delay; 3) Emotional impact and 4) Supporting students in clinical practice. Students recognised their resilience and felt proud of their contribution during this healthcare crisis but feared transmitting COVID-19 to family. Educational and emotional support provided by tutors, clinical staff and the university was deemed essential by students during this placement.ConclusionsDespite the pressure hospitals were under during the pandemic, students had positive clinical placement experiences and perceived these experiences to have contributed to their professional and personal growth.Implications for practiceThis study supports the argument for clinical placements to continue throughout healthcare crisis periods, albeit with additional learning and emotional support in place.Clinical placement experiences during the pandemic prompted a deep sense of pride amongst radiography students in their profession and contributed to the development of professional identity.     

Radiography education in 2022 and beyond - Writing the history of the present: A narrative review

ObjectivesThe COVID-19 pandemic had a major effect on teaching and learning. This study aimed to describe a range of teaching, learning, and assessment strategies related to radiography education which have become more common due to the pandemic through a narrative literature review.Key findingsEducational change in radiography was accelerated by the disruption caused by the pandemic. Changes included the site and mode of teaching and conducting of assessment. While some of the digital transformation trends were introduced before the pandemic, others were further amplified during this period of time. Alternative solutions such as virtual reality technology, gamification, and technology-enhanced learning were especially salient and have the potential to mitigate challenges brought about by the pandemic. The use of technology in the clinical setting, in assessment, and to facilitate feedback, are important tools for improving learners' clinical skills performance. Collectively, these digital technologies can maximise learning and support mastery of knowledge, skills and attitudes.ConclusionThe pandemic has cast a new light on existing methodologies and pedagogies in education. This review suggests that digital technology is shaping teaching and learning within radiography education and also that educators cannot ignore this digital shift. With the digital trajectory, it would be highly useful to transform approaches to education within radiography to support learning as radiography education moves towards the new normal era.Implications for practiceDigital technology in education can help improve the learning experience for learners but educators need to be equipped with the technological skills and be adaptable to these changes. Continual sharing of experiences and knowledge among radiography educators is essential. Safety nets need to be in place to ensure digital inclusiveness and that no learner gets left behind due to the digital divide in education.     

Supporting radiography clinical placements in Ireland during the COVID-19 pandemic: The practice educators perspective

IntroductionThe COVID-19 pandemic has significantly impacted healthcare services and the clinical learning environment. Several studies have investigated radiography students' experiences of clinical placement during the pandemic; however, few have investigated the Clinical Practice Educator's (CPEs) perspective. CPEs play a pivotal role in supporting clinical education.MethodA qualitative study was conducted using a purposeful sample of twenty-two CPEs, each working in a different Irish hospital. Four semi-structured focus groups were used to gather data. To maintain reasonable homogeneity, CPEs who were new to the role (n = 8) were assigned a separate focus group from experienced CPEs (n = 14). Inductive thematic analysis was applied.ResultsCPEs experienced role expansion, particularly in managerial and administrative aspects of the role. They described arranging COVID-19 vaccinations locally for radiography students and the complexities of student rostering during the pandemic. CPEs perceived the pandemic to have impacted students' emotional wellbeing with ‘high anxiety levels’ and ‘loneliness’ being reported. They also perceived issues with clinical readiness and the student transition to clinical practice. Many challenges were faced by CPEs including arranging clinical recovery time for numerous students when sites were already at full capacity, fewer learning opportunities due to decreased patient throughput and range of imaging examinations, social distancing constraints, resistance from staff to student placements, and a shortage of staff for student supervision. Flexibility, communication, and multi-level support helped CPEs to fulfil their role.ConclusionThe results provide insight into how CPEs supported radiography clinical placements during the pandemic and into the challenges faced by CPEs in their role. CPEs supported student placement through multi-level communication, teamwork, flexibility, and student advocacy.Implications for practiceThis will aid understanding of the support mechanisms needed by CPEs to provide quality clinical placements.     

A review of the impact of the COVID-19 pandemic on pre-registration medical radiation science education

ObjectiveThe COVID-19 pandemic has changed traditional ways to provide pre-registration medical radiation science (MRS) (medical imaging and radiation therapy) education. This literature review explores the published pre-registration MRS education curriculum adaptations implemented in response to the pandemic and effects of the adaptations on stakeholders.Key findingsEleven articles were identified through a systematic literature search. The included articles covered the pre-registration MRS curriculum adaptations implemented in response to the pandemic in 12 countries of five continents. Through changing content delivery and assessment modes from face-to-face to online, non-practical classes and academic assessments could continue without significant interruptions. However, cancellation/postponement of practical classes and clinical placements was common during COVID-19 lockdown. Simulated learning was used by some institutions to replace some practical classes and placements. Among the stakeholders of MRS education (students, academics and clinical educators), the students were most affected. The main impacts were negative psychological effects and learning experiences. For the academics, they had common concerns about online learning quality and assessment integrity.ConclusionThis review of the early publications in the first year of the pandemic provides an illustration of the MRS curriculum adaptations implemented in five continents covering both English and non-English speaking countries and their effects on the stakeholders as yet. It is expected that more articles on this area will be published over time and hence allowing a more comprehensive review in the future.Implications for practiceThe included articles show provision of wellbeing support, good planning of online content delivery based on sound pedagogical approaches, implementation of computer-based simulation tools suitable for home-based learning environment and use of authentic online assessments would address the impacts on the students and academics.     

The global impact of the COVID-19 pandemic on clinical radiography practice: A systematic literature review and recommendations for future services planning

IntroductionWorldwide, reports and experiences indicate that there has been extensive re-organisation within diagnostic imaging and radiotherapy departments in response to the COVID-19 pandemic. This was necessary due to changes in workload and working practice guidelines that have evolved during the pandemic. This review provides a comprehensive summary of the global impact of the COVID-19 pandemic on radiography practice, service delivery and workforce wellbeing.MethodsA systematic review methodology was adopted to obtain data from primary studies of qualitative, quantitative, and mixed methods designs from databases (PubMed, Science Direct, Cumulative Index of Nursing and Allied Health Literature [CINAHL], and SCOPUS: all 2020 to present). The included articles were subjected to information extraction and results-based convergent synthesis.ResultsThe electronic database search yielded 10,420 articles after removal of duplicates. Of these, 31 articles met the final inclusion criteria with some (n = 8) fully focussed on radiotherapy workforce and service delivery. The pandemic impact on radiography practice is broadly themed around: training, communication, and information dissemination; infrastructure, technology, and clinical workflow; and workforce mental health and well-being.ConclusionGlobally, most radiographers received inadequate training for managing COVID-19 patients during the initial acute phase of the pandemic. Additionally, there were significant changes to clinical practice, working patterns and perceived increase in workload due to surges in COVID-19 patients and the consequent strict adherence to new infection protocols. These changes, coupled with fear emanating from the increased risk of the workforce to contracting the infection, contributed to anxiety and workplace-related stress during the pandemic.Implications for practiceLocal pandemic response strategies must be appropriately developed from standard protocols in readiness for safe clinical practice and well-being management training of practitioners.     

The impact of COVID-19 upon student radiographers and clinical training

IntroductionTo investigate student clinical placement concerns and opinions, during the initial COVID-19 pandemic outbreak and to inform educational institution support planning.MethodsBetween mid-June to mid-July 2020, educational institutions from 12 countries were invited to participate in an online survey designed to gain student radiographer opinion from a wide geographical spread and countries with varying levels of COVID-19 cases.Results1277 respondents participated, of these 592 had completed clinical placements during January to June 2020. Accommodation and cohabiting risks were identified as challenging, as was isolation from family, travel to clinical placements, and to a lesser extent childcare. Students stated they had been affected by the feeling of isolation and concerns about the virus whilst on placement. Overall 35.4% of all respondents were ‘Not at all worried’ about being a radiographer, however, 64.6% expressed varying levels of concern and individual domestic or health situations significantly impacted responses (p ≤ 0.05). Year 4 students and recent graduates were significantly more likely to be ‘Not worried at all’ compared to Year 2 and 3 students (p ≤ 0.05). The need for improved communication regarding clinical placements scheduling was identified as almost 50% of students on clinical placements between January to June 2020 identified the completion of assessments as challenging. Furthermore, only 66% of respondents with COVID-19 imaging experience stated being confident with personal protective equipment (PPE) use.ConclusionStudent radiographers identified key challenges which require consideration to ensure appropriate measures are in place to support their ongoing needs. Importantly PPE training is required before placement regardless of prior COVID-19 imaging experience.Implications for practiceAs the next academic year commences, the study findings identify important matters to be considered by education institutions with responsibility for Radiography training and as students commence clinical placements during the on-going global COVID-19 pandemic.     

How to safely and sustainably reorganise a large general radiography service facing the COVID-19 pandemic

ObjectivesThis paper aims to share our experience in reorganising our general radiography service during the coronavirus disease (COVID-19) pandemic from the viewpoint of a large tertiary referral medical centre.Key findingsRe-organization of the radiography workforce, patient segregation, and modification of routine radiographic practices are key measures to help radiographic services deal with the COVID-19 pandemic. Specific emphasis on deploying more mobile radiographic units, segregating equipment, developing consistent image acquisition workflows, and strict adherence to infection control protocols are paramount to minimize the possibility of in-hospital transmission and ensure a safe environment for both patients and staff. Streamlining communication channels between leadership and ground staff allows quick dissemination of information to ultimately facilitate safe provision of services.ConclusionCOVID-19 has drastically altered the way general radiography teams provide services. The institution of several key measures will allow hospitals to safely and sustainably provide radiographic services. To date, there have been zero incidences of radiographer healthcare worker transmission within our institution during the course of work.Implication for practiceRadiographers are facing the challenge of providing high-quality services while simultaneously minimizing pathogen exposure to staff and patients. Our experience may lend support to other radiographic services responding to the COVID-19 outbreak and serve as a blueprint for future infectious disease outbreak contingency plans.     

The impact of the Covid-19 pandemic on the mental health and work morale of radiographers within a conventional X-ray department

IntroductionThere is a plethora of literature that has described the negative impact of the COVID-19 pandemic on the mental health of healthcare staff worldwide. Our aim was to investigate the physical and mental demands of mobile x-ray imaging on radiographers during the first wave of the COVID-19 pandemic, within a local NHS Trust.MethodsA total of 16 participants from 1 NHS Trust took part within this study. Both quantitative and qualitative data was obtained through an online survey. Statistical data was obtained via the Trust Radiology Information System (RIS). Data was gathered for the thirteen weeks from 23rd March to 21st June 2020 (the first wave); direct comparison was made to the same period in 2019.ResultsThree key themes emerged from the data. These include mental health challenges/work morale in Radiology, demand of mobile imaging and departmental and Trust-wide mental health support. Results indicate a high demand in mobile imaging which has made a significant difference in the working life of some radiographers.ConclusionThe COVID-19 pandemic has significantly affected the mental health of a proportion of radiographers at this Trust. Results indicate high workload and demand in mobile imaging has made a significant difference to the working life of radiographers, specifically the ones who were relatively newly qualified.Implications for practiceTwo key interventions are proposed from this study. The first one is to provide and promote mental health support within radiology departments. The second is to encourage dual working on mobile x-ray examinations to help manage the emotional and physical burden.     

Online teaching and learning through the students’ eyes – Uncertainty through the COVID-19 lockdown: A qualitative case study in Gauteng province,South Africa

IntroductionIn South Africa, online learning has been adopted to maintain the momentum of learning. The need for social distancing has resulted in the cancellation of many face-to-face activities that comprised the curriculum within higher education. This study explored the experiences of undergraduate diagnostic radiography students of online teaching and learning during the COVID-19 lockdown period.MethodsA qualitative case study design was adopted. Purposive sampling was employed to select undergraduate diagnostic radiography students at the study institution. One-on-one online interviews were audio recorded with fourteen (n = 14) students from second to fourth year and were transcribed verbatim. Data were analysed through content analysis.ResultsTwo main themes emerged: (1) Maintaining balance in the new ‘normal’; (2) Enablers for an inclusive learning environment. The change in the method of teaching has highlighted the requirements for adequate teaching and learning. The students in the study were of the view that they deserve an equal opportunity to quality online education.ConclusionThe study reveals that the participants were concerned about the transition from face-to-face lectures to the online system. They felt they were required to adjust without adequate consideration of the prerequisites for the process, such as devices and data availability.Implications for practiceRadiography is both technical and theoretical. Therefore, the integration of online teaching and learning could be used to enhance digital literacy within the South African context.     

Online learning during the COVID-19 pandemic: Perceptions of allied health sciences undergraduates

IntroductionThe purpose of this study was to determine the perceptions of Allied Health Sciences undergraduates towards online learning during the COVID 19 outbreak.MethodsA cross-sectional study was conducted with undergraduates of the Faculty of Allied Health Sciences, University of Peradeniya, Sri Lanka. A self-administered online questionnaire consisted of four sections to evaluate demographic information; details of online learning; perspectives and challenges on online learning were used for data collection.ResultsA total of 518 responses were received from the five disciplines of radiography (32.8%), nursing (24.9%), medical laboratory sciences (18.2%), pharmacy (14.5%), and physiotherapy (9.7%), resulting in a 76.4% response rate. The majority preferred smartphones (73.2%) for online access, and Zoom is the most utilized online communicating platform (72.8%). The overall respondent's perception score ranged from 9 to 27 (Positive ≥ 18, Neutral = 18, Negative ≤ 18) with a mean (SD) of 20.4 (4.0). Even though the majority (59.7%) agreed that online learning is more comfortable to communicate than conventional learning, most respondents (48.3%) have a negative perception towards offering practical and clinical-based subjects online. Poor internet connections (67.0%) and the lack of electronic devices (53.3%) were the most significant challenges encountered during online learning.ConclusionThe majority of the students have a positive perception towards online learning. Online learning appears to be an efficient learning strategy when students have equal access to online facilities.Implications for practiceAlthough the allied health undergraduates faced several challenges, they demonstrated their versatility and acceptance of the online learning strategy during the COVID-19 pandemic. Therefore a well-structured online learning programme will be beneficial for students to continue their studies during a pandemic.     

The impact of teaching experimental research on-line: Research-informed teaching and COVID-19

IntroductionAs part of the BSc (Hons) Diagnostic Radiography programme students learn and undertake research relevant to their development as first post radiographers (dose optimisation and image quality) within the Research-Informed Teaching experience (RiTe). Due to the COVID-19 pandemic, the delivery of RiTe to our year 2 students was moved to an online format using Microsoft Teams and Blackboard Collaborate and focused on a key area of current practice - COVID-19 and chest X-ray imaging. Within RiTe students are placed into collaborative enquiry-based learning (CEBL) groups to share tasks, but to also support and learn from one another.MethodsAn online survey was used to explore the year 2 student cohort task value and self-efficacy of this online version of RiTe.ResultsA 73% (32/44) response rate was achieved. Students found the online version of RiTe to be a positive learning and development experience. There was strong agreement that they not only found it relevant to their area of practice (task-value), but also strongly agreed that they understood and could master the skills taught (self-efficacy).ConclusionThis online version of RiTe was effectively structured to help scaffold student learning and development of research data analysis skills despite the lack of face-to-face teaching. The students also valued the topic area (COVID-19 and chest X-ray imaging). A blended learning approach with RiTe will be used next year with a combination of collaborative online teaching and physical data collection and analysis in the university-based X-ray imaging laboratory. Further evaluation and data collection will also be undertaken.Implications for practiceUniversity-based empirical work in groups to learn about research can be replaced by an online mechanism whilst still maintaining task-value and acceptable self-efficacy.     

Coronavirus Disease 2019 (COVID-19) Pandemic Shifts Inpatient Imaging Utilization

ObjectiveThe coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on imaging utilization across practice settings. The purpose of this study was to quantify the change in the composition of inpatient imaging volumes for modality types and Current Procedural Terminology–coded groups during the COVID-19 pandemic.MethodsA retrospective study of inpatient imaging volumes in a large health care system was performed, analyzing weekly imaging volumes by modality types (radiography, CT, MRI, ultrasound, interventional radiology, nuclear medicine) in years 2020 and 2019. The data set was split to compare pre-COVID-19 (weeks 1-9) and post-COVID-19 (weeks 10-16) periods. Further subanalyses compared early post-COVID-19 (weeks 10-13) and late post-COVID-19 (weeks 14-16) periods. Statistical comparisons were performed using χ² and independent-samples t tests.ResultsCompared with 2019, total inpatient imaging volume in 2020 post-COVID-19, early and late post-COVID-19 periods, declined by 13.6% (from 78,902 to 68,168), 16.6% (from 45,221 to 37,732), and 9.6% (from 33,681 to 30,436), respectively. By week 16, inpatient imaging volume rebounded and was only down 4.2% (from 11,003 to 10,546). However, a statistically significant shift (P < .0001) in the 2020 composition mix was observed largely comprised of radiography (74.3%), followed by CT (12.7%), ultrasound (8%), MRI (2.4%), interventional radiology (2.3%), and nuclear medicine (0.4%). Although the vast majority of imaging studies declined, few Current Procedural Terminology–coded groups showed increased trends in imaging volumes in the late post-COVID-19 period, including CT angiography chest, radiography chest, and ultrasound venous duplex.DiscussionDuring the COVID-19 pandemic, we observed a decrease in inpatient imaging volumes accompanied by a shift away from cross-sectional imaging toward radiography. These findings could have significant implications in planning for a potential resurgence.     

Brachytherapy care during the COVID-19 pandemic: Practice statement from a cancer center in Wuhan,China

PurposeCOVID-19 broke out in late 2019 and rapidly spread around the world and became a pandemic. This highly contagious disease affects routine health care services and patients with cancer who are susceptible to it. Delivering brachytherapy on time is critical for patients with cancer to get better prognosis. The purpose of this study is to present workflow and standard for radiation centers to deliver brachytherapy and avoid cross-infection during the COVID-19 pandemic.Methods and MaterialsThis study combined previous literature and guidelines of precaution with clinical experience in the COVID-19 pandemic.ResultsA workflow covering patients' screening, health care workers’ precaution, training, and other aspects of the whole brachytherapy procedure was established.ConclusionsFrom the reopening of radiation center to mid-May in 2020, there is no hospital infection of COVID-19 in patients or health care workers. This recommendation is effective and helpful to other cancer centers.     

Management of patients with suspected or confirmed COVID-19, in the radiology department

ObjectivesFrom December 2019, a novel coronavirus disease named COVID-19 was reported in China. Within 3 months, the World Health Organization defined COVID-19 as a pandemic, with more than 370,000 cases and 16,000 deaths worldwide. In consideration of the crucial role of diagnostic testing during COVID-19, the aim of this technical note was to provide a complete synthesis of approaches implemented for the management of suspected or confirmed COVID-19 patients.Key findingsThe planning of a robust plan to prevent the transmission of the virus to patients and department staff members should be fundamental in each radiology service. Moreover, the speed of spread and the incidence of the pandemic make it necessary to optimize the use of personal protective devices and dedicated COVID-19 equipment, given the limited availability of supplies.ConclusionIn the management of radiographic and CT imaging, staff should take special precautions to limit contamination between patients and other patients or professionals.Implications for practiceAn isolated imaging room should be dedicated to suspected or confirmed COVID-19 cases, including radiography and CT scanners. This paper will provide guidance concerning disposable protective gear to be utilized, as well as on the cleaning and sanitation of radiology room and equipment.     

Prevalencia y factores de desgaste profesional en radiólogos durante la pandemia COVID-19

BackgroundThe coronavirus 2019 (COVID-19) epidemic spread throughout the world from the beginning of 2020, increasing healthcare professionals’ workloads and levels of physical and emotional stress.AimsTo determine the prevalence of burnout syndrome in Spanish radiologists during the COVID-19 pandemic and the factors associated with the development of this syndrome, and to compare these findings with those obtained before the pandemic.MethodsThis observation study took place between April 2020 and August 2020 (during the pandemic) through an online survey. A total of 150 responses were obtained. Demographic and work-related information was compiled. Burnout syndrome was measured with the Maslach Burnout Inventory Human Services Survey (MBI-HSS). The prevalence and characteristics of burnout syndrome obtained in this survey were compared with those of the same survey done in 2019. We performed a statistical analysis to identify possible risk factors and protective factors associated with this syndrome and to determine the homogeneity of the two samples.ResultsThe prevalence of burnout syndrome increased during the COVID-19 pandemic (49.3% vs. 33.6%, p = 0.002). No risk factors or protective factors that were valid both before and after the pandemic were identified. No correlations were identified between sociodemographic or work-related characteristics and burnout syndrome.ConclusionThis study demonstrates that burnout syndrome increased significantly in radiologists during the COVID-19 pandemic, affecting nearly half of all those who responded to the survey. These results underline the need to assess support for professional wellbeing of radiologists in Spain. No correlations were identified between burnout and gender, age, number of calls, years in the job, annual income, teaching, marital status, number of children, or type of contract.
