Antibody responses to SARS-CoV-2 spike protein in a cohort of renal transplant recipients following two-dose primary immunization - A Caribbean country's perspective.

This study compares the humoral immune response of a cohort of renal transplant recipients (RTRs), in Trinidad & Tobago following two-dose primary immunization with non-mRNA vaccines amidst the COVID-19 pandemic. RTRs along with healthy, age-and gender-matched controls received either the adenoviral vector vaccine, AstraZeneca-Vaxzevria (AZ) or the inactivated vaccine, Beijing CNBG-BBIBP- CorV/Sinopharm (SP). Samples were taken after completion of a two-dose primary immunization during the period November 2021 to December 2021, at a mean interval of 138 days following immunization. 38/72 RTRs (53 %) failed to generate any protective antibody responses, compared with 7/73 participants, approximately 10 % in the healthy, age and gender-matched control group. In the RTRs, there was no significant correlation of their antibody concentration with either the timing of sample collection or the interval since transplantation. The study provides necessary information about the humoral response after two- doses of non-mRNA vaccines in a group of transplant recipients.

Ovarian Cancer in the Older Manitoban Population-Treatment Tolerance and Cancer-Related Outcomes: A Manitoba Ovarian Cancer Outcomes (MOCO) Group Study.

BACKGROUND: In Canada, individuals with gynecologic reproductive organs (ovaries, fallopian tubes, uterus) over the age of 70 comprise a large proportion of epithelial ovarian cancer patients. These patients often have co-morbidities, polypharmacy, or decreased functional status that may impact treatment initiation and tolerance. Despite this, there is limited evidence to guide treatment for older patients diagnosed with ovarian epithelial carcinoma. METHODS: This is a retrospective study with data from Manitoba, Canada. The data were obtained from the Manitoba Ovarian Cancer Database, the Manitoba Cancer Registry, and electronic health records. All individuals with epithelial ovarian, fallopian tube, or peritoneal cancer diagnosed between 2009 and 2018 were identified. Patients aged > 70 at the time of diagnosis were included in the study cohort. RESULTS: Four hundred and forty individuals were included. The majority had advanced stage disease (56%). Moreover, 59% of patients received no chemotherapy. Of the patients who received chemotherapy, 20% received <2 cycles and 21% required a dose reduction due to toxicity. Univariable and multivariable analysis identified advanced stage (p < 0.001), treatment modality (p < 0.001), and advanced age at diagnosis (p < 0.001) with poorer overall survival. CONCLUSIONS: Our study demonstrated a high rate of chemotherapy dose reduction and discontinuation in the elderly epithelial ovarian cancer population. Further research is needed to identify risk factors for treatment discontinuation and intolerance in this population.

Trigger warnings as tools for learning-theorising an evolving cultural concept.

BACKGROUND: While definitions of trigger warnings vary, it is generally accepted that they caution about potential reactions arising from exposure to distressing material. Controversy surrounds use of warnings in education, with concerns noted regarding impacts on academic freedom, "coddling", thereby undermining resilience, reinforcement of traumatised identity and enablement of avoidance. Proponents of warnings position them as accommodations for those affected by trauma, enhancing inclusion, and suggest warnings empower choice and enable informed engagement in learning. A recent meta-analysis of warnings' efficacy demonstrated no effect on affective responses or comprehension. Findings regarding avoidance suggested warnings may increase engagement with material. Synthesis of heterogeneous results relating to context of warning application necessitates cautious interpretation of findings. Furthermore, controlled experimental designs do not reflect complex ecologies of social learning environments. METHODS: Evidence relating to warnings in healthcare professions education remains limited. We undertake a narrative review and synthesis of evidence regarding the role and functions of trigger warnings from a range of disciplines, to inform healthcare education practice. We apply this evidence in considering how warnings may act within a range of theoretical frameworks for healthcare professionals educations including andragogy, self-directed learning and, ultimately, transformative learning. Tensions between exposure to emotionally stimulating learning episodes and the necessity of emotion for learning while simultaneously attending to learners' needs and fulfilling educators' responsibilities are explored. We probe gaps and contentions in existing theoretical frameworks for learning, and consider implications of recognised limitations with reference to warnings. We summarise by proposing a conceptual model for the role of warnings that considers wider salient factors for fostering effective learning. DISCUSSION AND CONCLUSIONS: Difficulties associated with deriving contextually-relevant evidence and conclusions relating to warnings as an evolving cultural concept are highlighted. We propose warnings as tools to enable critical reflection and emotional literacy, to curate effective learning environments and support humanistic healthcare professional identity formation, within wider trauma-informed pedagogies and educator practice.

Twelve tips for implementing trigger or content warnings in healthcare professions education.

Trigger warnings are statements offering prior notification of sensitive content, allowing recipients to prepare for and avoid ensuing distress. Students are increasingly reporting expectations for warnings in classrooms and learning contexts. Discussions regarding use of warnings have clear relevance to healthcare education, which regularly explores sensitive content. Their use has been positioned as a measure for inclusive education and as a means to enhance trauma awareness and empathy. Expectations for warnings need to be considered in the context of preparedness for professional practice. This Twelve Tips paper explores the evidence in relation to warnings and its applicability to social learning contexts. These tips highlight considerations and strategies for the use of warnings in the context of healthcare education, balancing issues of inclusivity, learner and educator wellbeing, and professional preparedness. These discussions are situated within the context of current classroom-based healthcare education.

Development of consensus-driven SPIRIT and CONSORT extensions for early phase dose-finding trials: the DEFINE study.

BACKGROUND: Early phase dose-finding (EPDF) trials are crucial for the development of a new intervention and influence whether it should be investigated in further trials. Guidance exists for clinical trial protocols and completed trial reports in the SPIRIT and CONSORT guidelines, respectively. However, both guidelines and their extensions do not adequately address the characteristics of EPDF trials. Building on the SPIRIT and CONSORT checklists, the DEFINE study aims to develop international consensus-driven guidelines for EPDF trial protocols (SPIRIT-DEFINE) and reports (CONSORT-DEFINE). METHODS: The initial generation of candidate items was informed by reviewing published EPDF trial reports. The early draft items were refined further through a review of the published and grey literature, analysis of real-world examples, citation and reference searches, and expert recommendations, followed by a two-round modified Delphi process. Patient and public involvement and engagement (PPIE) was pursued concurrently with the quantitative and thematic analysis of Delphi participants' feedback. RESULTS: The Delphi survey included 79 new or modified SPIRIT-DEFINE (n = 36) and CONSORT-DEFINE (n = 43) extension candidate items. In Round One, 206 interdisciplinary stakeholders from 24 countries voted and 151 stakeholders voted in Round Two. Following Round One feedback, one item for CONSORT-DEFINE was added in Round Two. Of the 80 items, 60 met the threshold for inclusion (≥ 70% of respondents voted critical: 26 SPIRIT-DEFINE, 34 CONSORT-DEFINE), with the remaining 20 items to be further discussed at the consensus meeting. The parallel PPIE work resulted in the development of an EPDF lay summary toolkit consisting of a template with guidance notes and an exemplar. CONCLUSIONS: By detailing the development journey of the DEFINE study and the decisions undertaken, we envision that this will enhance understanding and help researchers in the development of future guidelines. The SPIRIT-DEFINE and CONSORT-DEFINE guidelines will allow investigators to effectively address essential items that should be present in EPDF trial protocols and reports, thereby promoting transparency, comprehensiveness, and reproducibility. TRIAL REGISTRATION: SPIRIT-DEFINE and CONSORT-DEFINE are registered with the EQUATOR Network ( https://www.equator-network.org/ ).

Using social media for patient and public involvement and engagement in health research: The process and impact of a closed Facebook group.

BACKGROUND: As part of a multifaceted approach to patient and public involvement and engagement (PPIE), alongside traditional methods, a closed Facebook group was established to facilitate PPIE feedback on various aspects of a project that used video-recording to examine risk communication in NHS Health Checks between June 2017 and July 2019. OBJECTIVE: To explore the process and impact of conducting PPIE through a closed Facebook group and to identify the associated benefits and challenges. METHODS: Supported by reflections and information from project meetings used to document how this engagement informed the project, we describe the creation and maintenance of the Facebook Group and how feedback from the group members was obtained. Facebook data were used to investigate levels and types of engagement in the closed Facebook group. We reflect on the challenges of using this method of engaging the public in health research. RESULTS: A total of 289 people joined the 'Risk Communication of Cardiovascular disease in NHS Health Checks' PPIE closed Facebook group. They provided feedback, which was used to inform aspects of the study, including participant-facing documents, recruitment, camera position and how the methodology being used (video-recorded Health Checks and follow-up interviews) would be received by the public. DISCUSSION: Using a closed Facebook group to facilitate PPIE offered a flexible approach for both researchers and participants, enabled a more inclusive method to PPIE (compared with traditional methods) and allowed rapid feedback. Challenges included maintaining the group, which was more labour intensive than anticipated and managing members' expectations. Suggestions for best practice include clear communication about the purpose of the group, assigning a group co-ordinator to be the main point of contact for the group, and a research team who can dedicate the time necessary to maintain the group. CONCLUSION: The use of a closed Facebook group can facilitate effective PPIE. Its flexibility can be beneficial for researchers, patients and public who wish to engage in the research process. Dedicated time for sustained group engagement is important. PATIENT OR PUBLIC CONTRIBUTION: Patient representatives were engaged with the development of the research described in this paper and a patient representative reviewed the manuscript.

Addressing inequitable access to hospice care.

The 'Lancet Commission on the Value of Death' proposes radical change and challenges the very core of hospice service provision. Without action, inequalities in access to hospice care will continue to be amplified. The COVID-19 pandemic brought increased needs and demands in the community setting but also provided opportunities for new palliative partnerships and ways of working. Returning to the status quo should not be an option. Rather moving towards a shared vision and purpose, which has the person and their community network at its centre, enables hospices to have a pivotal role and bring about more equitable palliative care.

Medical students' views on the value of trigger warnings in education: A qualitative study.

BACKGROUND: Trigger warnings-advance notification of content so recipients may prepare for ensuing distress-feature in discussions in higher education. Students' expectations for warnings in some circumstances are recognised, and some educators and institutions have adopted use. Medical education necessitates engagement with potentially distressing topics. Little is known about medical students' expectations regarding warnings in education. METHODS: All students from a 4-year graduate-entry UK medical degree programme were contacted via digital message outlining study details and were openly sampled. Qualitative methodology was chosen to explore participant expectations, experiences and meanings derived from experiences. Students participated in semi-structured interviews exploring perspectives on functions, benefits and drawbacks of trigger warnings in classroom-based medical education. We analysed interview transcripts using thematic analysis. RESULTS: Thirteen semi-structured, qualitative interviews were undertaken. Themes in the following areas were identified: (1) students' experiences influence understanding of trauma and trigger warnings, (2) warnings as mediators of learning experiences, (3) professional responsibilities in learning, (4) exposure to content, (5) professional ethos in medical education and (6) how to issue trigger warnings. Students recognised the term 'trigger warning', and that warnings are an accommodation for those affected by trauma. Students' conceptualisation of warnings was influenced by personal experiences and peer interactions both within and outside education. Students expressed both support and concerns about use of warnings and their ability to influence learning, assuming of responsibility and professional development. DISCUSSION: Diverse student opinions regarding warnings were identified. Most students suggested that warnings be used prior to topics concerning recognised traumas. Incremental exposure to distressing content was recommended. Students should be supported in managing own vulnerabilities and needs, while also experiencing sufficient formative exposure to develop resilience. Greater understanding of trauma prevalence and impacts and underpinnings of warnings amongst students and educators are recommended to optimise education environments and professional development.

The impact of Covid-19 pandemic on hospices: A systematic integrated review and synthesis of recommendations for policy and practice.

Background: The Covid-19 pandemic resulted in the development of numerous recommendations for practice and policy for specialist palliative care provided by hospices in United Kingdom (UK), as hospices were significantly affected by the pandemic and protections put in place.The aim of this review is to identify and synthesise recommendations or implications for policy and practice that have been generated for adult hospice specialist palliative care during the first 24 months of the Covid-19 pandemic. Methods: AMED, BNI, CINAHL, EMBASE, EMCARE, HMIC, Medline, PsycINFO, PubMed databases were searched for peer-reviewed papers, as well as hand searchers for grey literature. Literature relating to hospices and Covid-19 in the UK were included and a thematic synthesis of recommendations for hospice policy and practice was undertaken. Results: 858 articles were identified with 12 meeting the inclusion criteria. Fifty-eight recommendations or implications were identified: 31 for policy, 27 for practice, and 10 covering both. Recommendations were organised under ten themes. There were several recommendations seeking to secure hospice resources to mitigate the short-term impact of the pandemic, as well as those focused on longer-term implications such as core funding. The impact of the pandemic on the quality of hospice care was the focus for numerous recommendations around improving integration of hospice care in the community, provision of bereavement support and better use of Advance Care Plans (ACP). However, there were significant gaps related to carer visitation in hospices, inequities of palliative care, or hospice-at-home services. Conclusion: The Covid-19 pandemic and protections exposed several ongoing policy and practice needs, especially around hospice resources, while generating novel issues for hospices to address. Significant policy gaps remain to be addressed to mitigate the impact of the pandemic on the quality of hospice specialist palliative care.

Hospices in the UK faced many challenges during the first two-years of the Covid-19 pandemic. In this time several research studies and reviews took place that provided hospices with recommendations for how to adapt their policies and clinical practices. In this review we identified 12 documents that contained 58 recommendations for hospices' policy and practice. We grouped these recommendations together under ten key themes. We found that there were several recommendations aiming to secure hospice resources to mitigate the short and longer-term impacts upon hospice funding. The impact of the pandemic on the quality of hospice care was the focus for numerous recommendations around improving integration of hospice care in the community, provision of bereavement support and better use of Advance Care Plans (ACP). However, there were significant gaps related to carer visitation in hospices, inequities of palliative care, or hospice-at-home services.

'Give Us The Tools!': development of knowledge transfer tools to support the involvement of patient partners in the development of clinical trial protocols with patient-reported outcomes (PROs), in accordance with SPIRIT-PRO Extension.

OBJECTIVES: (a) To adapt the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT)-patient-reported outcome (PRO) Extension guidance to a user-friendly format for patient partners and (b) to codesign a web-based tool to support the dissemination and uptake of the SPIRIT-PRO Extension by patient partners. DESIGN: A 1-day patient and public involvement session. PARTICIPANTS: Seven patient partners. METHODS: A patient partner produced an initial lay summary of the SPIRIT-PRO guideline and a glossary. We held a 1-day PPI session in November 2019 at the University of Birmingham. Five patient partners discussed the draft lay summary, agreed on the final wording, codesigned and agreed the final content for both tools. Two additional patient partners were involved in writing the manuscript. The study compiled with INVOLVE guidelines and was reported according to the Guidance for Reporting Involvement of Patients and the Public 2 checklist. RESULTS: Two user-friendly tools were developed to help patients and members of the public be involved in the codesign of clinical trials collecting PROs. The first tool presents a lay version of the SPIRIT-PRO Extension guidance. The second depicts the most relevant points, identified by the patient partners, of the guidance through an interactive flow diagram. CONCLUSIONS: These tools have the potential to support the involvement of patient partners in making informed contributions to the development of PRO aspects of clinical trial protocols, in accordance with the SPIRIT-PRO Extension guidelines. The involvement of patient partners ensured the tools focused on issues most relevant to them.

Medical educators' views and experiences of trigger warnings in teaching sensitive content.

BACKGROUND: Trigger warnings-prior notification of topics so recipients may prepare for ensuing distress-are encountered widely in contemporary culture. Students at some universities have expressed expectations for trigger warnings. Medical education routinely exposes students to numerous potentially distressing topics. However, this topic remains understudied in medical education. Little is understood about educators' views or practice relating to warnings in the context of medical education. METHODS: Twenty medical educators from a medical degree programme in the UK participated in a semi-structured qualitative interview study, exploring medical educators' views and experiences of managing distressing situations and, specifically, their use of warnings. We analysed interview transcripts by thematic coding and identified themes. RESULTS: Analysis identified themes relating to educators' conceptualisation of trigger warnings and rationale for use, concerns about the use of warnings and the critical purpose of medical school in ensuring preparedness for clinical practice. Participants shared that warnings were given to empower students in approaching distressing topics and to enable engagement with learning. Warnings acknowledged that some experiences would be distressing and normalised and signalled acceptability of emotional responses. Decisions to use warnings were influenced by the nature of content and, reactively, in response to experiences of student distress. Terminology regarding trigger warnings was interpreted varyingly by participants. A broad variety of topics were identified as potentially sensitive. A number of concerns were noted regarding the use of warnings. DISCUSSION: Warnings alone did not fulfil educators' responsibility in supporting students' professional development, but may be a useful adjunct, signalling that self-care is valued and should be prioritised. Despite frequent use of warnings, individual educator practice was shaped by varying rationale. A framework that addresses competing tensions of preventing distress and supporting professional development is needed as part of a trauma-informed approach to medical education.

Quality improvement report: setting up a hospital at night service, limitations of bleep filtering and using an electronic task management system.

The 'hospital at night' concept was developed at a joint conference of the London Deanery and Clinical Staff in 2002, as an issue for education and service provision. At the start of the project, our trust had issues with both the structure of the hospital at night handover and the working practices overnight. The vision was to improve team working out of hours, expedite review of sick patients and reorganise care to seek a reduction in bleeps to medical junior doctors overnight in a way that all patients had access to the right person with the right skills for their needs at the right time. The hospital at night project at our hospital was started in 2019 by a multidisciplinary working group. We tried bleep filtering for 4 months and this was later followed on by the development of an electronic out of hour's task list as part of our hospital at night set-up. The bleep analysis data showed an improved distribution of workload but the process was dependent on individuals. The electronic task management system was built in pre-existing online software. The system helped prioritise and review tasks requested by nurses on medical wards. But it was not without its limitations. We worked with the local information technology (IT) team to improve speed and proposed developing an IT solution that is fast and not desktop based to ensure tasks can be assigned and viewed while on the go. The project was overall a success as it demonstrated positive feedback from junior doctors, improved perception of teamwork and ability to take rest breaks. It also demonstrated a drop in ward-based cardiac arrest rates. The hospital at night project at our trust remains a work in progress, but a lot of positive changes have been delivered.

What do we know about the impact of the Covid-19 pandemic on hospices? A collaborative multi-stakeholder knowledge synthesis.

Background: Prior to undertaking a study looking at the effects of the COVID-19 pandemic upon lived experiences of hospice services in the West Midlands, we sought to identify the range of issues that hospice service users and providers faced between March 2020 and July 2021, and to provide a report that can be accessed and understood by all interested stakeholders. Methods: We undertook a collaborative multi-stakeholder approach for scoping the range of potential issues and synthesising knowledge. This involved a review of available literature; a focus group with hospice stakeholders; and a collaborative knowledge exchange panel. Results: The literature on the effects of the COVID-19 pandemic on hospices remains limited, but it is developing a picture of a service that has had to rapidly adapt the way it provides care and support to its service users, during a period when it faced many fundamental challenges to established ways of providing these services. Results: The impacts of many of the changes on hospices have not been fully assessed. It is also not known what the effects upon the quality of care and support are for those with life-limiting conditions and those that care for them. We found that the pandemic has presented a new normative and service context in which quality of care and life itself was valued that is, as yet, poorly understood.

Low-grade serous carcinoma (LGSC): A Canadian multicenter review of practice patterns and patient outcomes.

OBJECTIVE: Patients with advanced low-grade serous carcinoma (LGSC) have poor long-term survival rates. As a rare histotype, there are uncertainties regarding the use of current therapies. Thus, we studied practice patterns and treatment outcomes as part of a national initiative to better understand and improve the care of women with advanced LGSC. METHODS: This retrospective cohort study was conducted in 5 Canadian referral institutions from 2000 to 2016. Data collection and pathology reporting were standardized. Outcome measures included overall survival (OS), progression-free survival (PFS), progression-free intervals (PFI), and time to next treatment (TTNT). Cox regression analysis was used to evaluate the effects of clinical and pathologic factors on outcomes and prognosis. RESULTS: There were 134 patients (stage II-IV) with a median follow-up of 32.4 months (range 1.6-228). Four primary treatments were compared across institutions: 1) surgery followed by chemotherapy (56%), 2) neoadjuvant chemotherapy (NACT) followed by surgery (27%), 3) surgery alone (9%), and 4) surgery followed by anti-hormone therapy (4%). Primary platinum/paclitaxel chemotherapy was used in 81%. Patients treated with NACT had worse PFS. Multivariable Cox regression analysis identified lesser residual disease, younger age, and primary peritoneal origin as variables significantly associated with better OS/PFS (p < 0.03). One institution had significantly better PFS than the others (p = 0.025), but this finding could be related to a higher frequency of primary peritoneal LGSC. PFI and TTNT intervals in patients with relapsed disease were not significantly different after the first relapse irrespective of treatment type. CONCLUSIONS: There are notable differences in practice patterns across Canada. This underscores the need for ongoing strategies to measure, evaluate and achieve optimal patient outcomes for women with advanced LGSC.

Subclinical thyroid dysfunction symptoms in older adults: cross-sectional study in UK primary care.

BACKGROUND: Subclinical thyroid dysfunction - abnormal serum thyrotrophin (thyroid-stimulating hormone; TSH) concentrations with normal free thyroxine (FT4) is common in older people. It remains unclear whether individuals with subclinical serum status experience an increased symptom profile. AIM: To compare the prevalence of those symptoms typically associated with overt thyroid dysfunction in older individuals with a subclinical and euthyroid serum profile. DESIGN AND SETTING: Cross-sectional study, nested within the Birmingham Elderly Thyroid Study (BETS); from 19 UK general practices. METHOD: Adults living in a community setting (aged ≥65 years), without overt thyroid dysfunction or associated treatment, self-reported the presence or absence of 18 symptoms (while serum result naïve). Serum concentrations of TSH and FT4 were measured to establish thyroid status. RESULTS: A total of 2870 individuals were screened: 2703 (94%) were categorised as euthyroid (normal), 29 (1%) subclinically hyperthyroid, and 138 (5%) subclinically hypothyroid. Symptoms were common in all groups. No significant differences in the prevalence of individual symptoms were observed between the euthyroid and subclinically hypothyroid groups nor in comparison with the subclinically hyperthyroid group. Multivariate logistic regression analysis failed to reveal an association between individual or multiple symptoms and subclinical status. CONCLUSION: Findings suggest that subclinical thyroid dysfunction does not confer a symptom burden in older individuals and support adherence to guidelines in the non-treatment of subclinical thyroid dysfunction. GPs may use the findings to reassure older people presenting with symptoms that subclinical thyroid dysfunction is an unlikely explanation. The presence of persistently abnormal TSH concentrations may be linked to long-term risks of cardiovascular disease, especially atrial fibrillation, but whether this should prompt treatment and whether such treatment alters vascular outcomes is unknown.

Exploring the use and quality of Internet discussion forums in pregnancy: A qualitative analysis.

BACKGROUND: The Internet is widely used as a source of health information to assist decision making in pregnancy. Concerningly, the quality of information shared on online pregnancy forums is unclear. Our objectives were to explore online pregnancy forum health-related use and evaluate quality of information shared. METHODS: This retrospective qualitative study had two phases of data collection and analysis. First, thematic analysis of a representative sample (n = 480) of posts explored motivators for forum use. Second, a subgroup (n = 153) of threads with clinical content was assessed for congruence with reputable sources. RESULTS: Common motivators for forum engagement were a desire for lived experience, unlimited access, and the opportunity to express emotions. Of 1098 responses sharing advice, information, or experience, 601 (54.7%) were accurate; 230 (20.9%) were erroneous, incomplete, or misleading; and 267 (24.3%) lacked credible evidence. Of these, 60 (5.5%) were potentially harmful. Responses often directed women to a health care practitioner, but concerningly, failed to refer ten women in need of urgent medical assessment. Few discussions were self-regulating, with only 12 of 230 (5.2%) poor-quality messages subsequently rectified. CONCLUSIONS: Exchange of information and emotional support among peers are key functions of online pregnancy forums. There is a modest prevalence of poor-quality or potentially harmful information but more concerningly a lack of peer moderation. We suggest health care practitioners ensure pregnant women have a clear understanding of when clinical consultation is required. Clinicians may wish to discuss the supportive community aspects of online forums in cases where offline support is lacking.

Stability of thyroid function in older adults: the Birmingham Elderly Thyroid Study.

BACKGROUND: Thyroid function tests (TFTs) are among the most requested tests internationally. However, testing practice is inconsistent, and potentially suboptimal and overly costly. The natural history of thyroid function remains poorly understood. AIM: To establish the stability of thyroid function over time, and identify predictors of development of overt thyroid dysfunction. DESIGN AND SETTING: Longitudinal follow-up in 19 general practices in the UK. METHOD: A total of 2936 participants from the Birmingham Elderly Thyroid Study (BETS 1) with a baseline TFT result indicating euthyroid or subclinical state were re-tested after approximately 5 years. Change in thyroid-stimulating hormone (TSH), free thyroxine (FT4), and thyroid status between baseline and follow-up was determined. Predictors of progression to overt dysfunction were modelled. RESULTS: Participants contributed 12 919 person-years; 17 cases of overt thyroid dysfunction were identified, 13 having been classified at baseline as euthyroid and four as having subclinical thyroid dysfunction. Individuals with subclinical results at baseline were 10- and 16-fold more likely to develop overt hypothyroidism and hyperthyroidism, respectively, compared with euthyroid individuals. TSH and FT4 demonstrated significant stability over time, with 61% of participants having a repeat TSH concentration within 0.5 mIU/L of their original result. Predictors of overt hypothyroidism included new treatment with amiodarone (odds ratio [OR] 92.1), a new diagnosis of atrial fibrillation (OR 7.4), or renal disease (OR 4.8). CONCLUSION: High stability of thyroid function demonstrated over the 5-year interval period should discourage repeat testing, especially when a euthyroid result is in the recent clinical record. Reduced repeat TFTs in older individuals is possible without conferring risk, and could result in significant cost savings.
