RESUMO

BACKGROUND: Barriers to accessing hospice and palliative care have been well studied. An important yet less researched area is why people approaching the end-of-life decline a referral when they are offered services. This review focused on synthesising literature on patients in the last months of life due to a cancer diagnosis who have declined a referral to end-of-life care. METHODS: Six academic databases were systematically searched for qualitative literature published between 2007 and 2021. Two researchers independently reviewed and critically appraised the studies. Using meta-ethnographic methods of translation and synthesis, we set out to identify and develop a new overarching model of the reasons patients decline end-of-life care and the factors contributing to this decision. RESULTS: The search yielded 2060 articles, and nine articles were identified that met the review inclusion criteria. The included studies can be reconceptualised with the key concept of 'embodied decisions unfolding over time'. It emphasises the iterative, dynamic, situational, contextual and relational nature of decisions about end-of-life care that are grounded in people's physical experiences. The primary influences on how that decision unfolded for patients were (1) the communication they received about end-of-life care; (2) uncertainty around their prognosis, and (3) the evolving situations in which the patient and family found themselves. Our review identified contextual, person and medical factors that helped to shape the decision-making process. CONCLUSIONS: Decisions about when (and for some, whether at all) to accept end-of-life care are made in a complex system with preferences shifting over time, in relation to the embodied experience of life-limiting cancer. Time is central to patients' end-of-life care decision-making, in particular estimating how much time one has left and patients' embodied knowing about when the right time for end-of-life care is. The multiple and intersecting domains of health that inform decision-making, namely physical, mental, social, and existential/spiritual as well as emotions/affect need further exploration. The integration of palliative care across the cancer care trajectory and earlier introduction of end-of-life care highlight the importance of these findings for improving access whilst recognising that accessing end-of-life care will not be desired by all patients.

RESUMO

BACKGROUND: This study focuses on the provision of supportive care services and programmes for cancer survivors post-treatment in Aotearoa New Zealand (NZ). It aims to aid our understanding of an often challenging and fragmented phase of cancer survivorship, and lay the groundwork for future research into the development of survivorship care in NZ. METHODS: This study employed a qualitative design using semi-structured interviews with a range of healthcare providers (n = 47) involved in service provision for cancer survivors post active treatment, including supportive care providers; clinical and allied health providers; primary health providers; and Maori health providers. Data were analysed using thematic analysis. RESULTS: We found that cancer survivors in NZ face a range of psycho-social and physical issues post-treatment. The provision of supportive care to meet these needs is currently fragmented and inequitable. The key barriers to improved supportive care provision for cancer survivors post-treatment include a lack of capacity and resources within the existing cancer care framework; divergent attitudes to survivorship care within the cancer care workforce; and a lack of clarity around whose responsibility post-treatment survivorship care is. CONCLUSIONS: Post-treatment cancer survivorship should be established as a distinct phase of cancer care. Measures could include greater leadership in the survivorship space; the implementation of a survivorship model(s) of care; and the use of survivorship care plans; all of which could help improve referral pathways, and clarify clinical responsibility for post-treatment survivorship care.

RESUMO

Background: The benefits of palliative care programs are well documented. However, the effectiveness of specialist palliative care services is not well established. The previous lack of consensus on criteria for defining and characterizing models of care has restrained direct comparison between these models and limited the evidence base to inform policy makers. A rapid review for studies published up to 2012 was unable to find an effective model. Aim: To identify effective models of community specialist palliative care services. Design: A mixed-method synthesis design reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Prospero: CRD42020151840. Data sources: Medline, PubMed, EMBASE, CINAHL and the Cochrane Database of Systematic Reviews were searched in September 2019 for primary research and review articles from 2012 to 2019. Supplementary search was conducted on Google in 2020 for policy documents to identify additional relevant studies. Results: The search yielded 2255 articles; 36 articles satisfied the eligibility criteria and 6 additional articles were identified from other sources. Eight systematic reviews and 34 primary studies were identified: observational studies (n = 24), randomized controlled trials (n = 5), and qualitative studies (n = 5). Community specialist palliative care was found to improve symptom burden/quality of life and to reduce secondary service utilization across cancer and noncancer diagnoses. Much of this evidence relates to face-to-face care in home-based settings with both round-the-clock and episodic care. There were few studies addressing pediatric populations or minority groups. Findings from qualitative studies revealed that care coordination, provision of practical help, after-hours support, and medical crisis management were some of the factors contributing to patients' and caregivers' positive experience. Conclusion: Strong evidence exists for community specialist palliative care to improve quality of life and reducing secondary service utilization. Future research should focus on equity outcomes and the interface between generalist and specialist care.

RESUMO

INTRODUCTION: This study aimed to evaluate differential attainment during higher surgical training (HST; all specialties) related to three ethnic cohorts: White UK (WUKG), Black and Minority Ethnic UK Graduates (BMEUKG), and International Medical Graduates (IMG). METHOD: Anonymised records of 266 HSTs (126 WUKG, 65 BMEUKG, 75 IMG; 7 years) in a single UK Statutory Education Body were examined. Primary effect measures were Annual Record of Competency Progression Outcome (ARCPO) and Fellowship of the Royal College of Surgeons (FRCS) pass. RESULTS: ARCPOs related to ethnicity and specialty were similar with the exception of general surgery (GS) trainees, four of whom received ARCPO 4 (GS 4.9% (75% BME; p=0.025) vs all other 0%). ARCPO 3 was commoner in women (22/76, (28.9%) than men 27/190 (14.2%), OR 2.46, p=0.006). FRCS pass rates (WUKG vs BMEUKG vs IMG) were 76.9%, 52.9% and 53.9% respectively (p=0.064) but unrelated to gender (M 70.4% vs F 64.3%). On multivariable analyses: ARCPO 3 was associated with Female gender and Maternity Leave (OR 8.05, p=0.001); FRCS pass with ethnicity (OR 0.21, p=0.028) and Hirsch Indices of ≥5 (OR 11.17, p=0.001). CONCLUSION: Differential attainment was plain with BMEUKG FRCS performance almost a third poorer than WUKG, and women twofold more likely to receive adverse ARCPOs, with return from statutory leave independently associated with training extension. Focused counter measures targeted at non-operative technical skills (including academic reach), Keeping in Touch, Return to Work, and re-induction programmed support are urgently needed for trainees at risk.

RESUMO

BACKGROUND: This study aimed to evaluate core surgical training (CST) differential attainment related to coronavirus disease 2019 (COVID-19), gender and ethnicity. The hypothesis was that COVID-19 adversely influenced CST outcomes. METHODS: A retrospective cohort study of 271 anonymised CST records was undertaken at a UK Statutory Education Body. Primary effect measures were Annual Review of Competency Progression Outcome (ARCPO), Membership of the Royal College of Surgeons (MRCS) examination pass and Higher Surgical Training National Training Number (NTN) appointment. Data were collected prospectively at ARCP and analysed with non-parametric statistical methods in SPSS. RESULTS: CSTs numbering 138 completed training pre-COVID and 133 peri-COVID. ARCPO 1, 2 and 6 were 71.9% pre-COVID versus 74.4% peri-COVID ( P =0.844). MRCS pass rates were 69.6% pre-COVID versus 71.1% peri-COVID ( P =0.968), but NTN appointment rates diminished (pre-COVID 47.4% vs. peri-COVID 36.9%, P =0.324); none of the above varied by gender or ethnicity. Multivariable analyses by three models revealed: ARCPO was associated with gender [m:f 1:0.87, odds ratio (OR) 0.53, P =0.043] and CST theme (Plastics vs. General OR 16.82, P =0.007); MRCS pass with theme (Plastics vs. General OR 8.97, P =0.004); NTN with the Improving Surgical Training run-through programme (OR 5.00, P <0.001). Programme retention improved peri-COVID (OR 0.20, P =0.014) with pan University Hospital rotations performing better than Mixed or District General-only rotations (OR 6.63, P =0.018). CONCLUSION: Differential attainment profiles varied 17-fold, yet COVID-19 did not influence ARCPO or MRCS pass rates. NTN appointment fell by one-fifth peri-COVID, but overall training outcome metrics remained robust despite the existential threat.

RESUMO

BACKGROUND: Personal protective equipment (PPE) adversely affects pulmonary gas exchange and may result in systemic hypercapnic hypoxaemia and headache. This study aimed to determine what extent PPE affects cerebral symptoms, global cerebral blood flow, and cognitive functional performance. METHODS: Higher surgical trainees participated in a randomized, repeated-measures, crossover study, completing 60 min of laparoscopic surgical simulation in both standard operating attire and type 3 PPE. Measurements were collected at baseline and after 60 min of simulation. The primary outcome measure was headache. Headache was examined using the validated visual analogue scale (VAS) and Environmental Symptoms Questionnaire C (ESQ-C), global cerebral blood flow with duplex ultrasonography, and visuospatial and executive gross/fine motor function with grooved peg board (GPB) and laparoscopic bead (LSB) board tasks. RESULTS: Thirty-one higher surgical trainees (20 men, 11 women) completed the study. Compared with standard operating attire, PPE increased headache assessment scores (mean(s.d.) VAS score 3.5(5.6) versus 13.0(3.7), P < 0.001; ESQ-C score 1.3(2.0) versus 5.9(5.1), P < 0.001) and was associated with poorer completion times for GPB-D (61.4(12.0) versus 71.1(12.4) s; P = 0.034) and LSB (192.5(66.9) versus 270.7(135.3) s; P = 0.025) tasks. Wearing PPE increased heart rate (82.5(13.6) versus 93.5(13.0) beats/min; P = 0.022) and skin temperature (36.6(0.4) versus 37.1(0.5)°C; P < 0.001), but decreased peripheral oxygen saturation (97.9(0.8) versus 96.8(1.0) per cent; P < 0.001). Female higher surgical trainees exhibited higher peripheral oxygen saturation across all conditions. No differences were observed in global cerebral blood flow as a function of attire, time or sex. CONCLUSION: Despite no marked changes in global cerebral blood flow, type 3 PPE was associated with increased headache scores and cerebral symptoms (VAS and ESQ-C) alongside impaired executive motor function highlighting the clinical implications of PPE-induced impairment for cognitive-clinical performance.

RESUMO

AIM: Community specialist palliative care (SPC) in Aotearoa New Zealand is provided by independent hospices. Substantial increase in demand for palliative care is projected in the next 20 years. We aimed to describe the current landscape of SPC services across Aotearoa whilst incorporating an equity lens. METHODS: A descriptive cross-sectional survey was undertaken to describe aspects of hospice service and populations served. Survey links were emailed to clinical, or service leads of hospices identified via Hospice New Zealand Website. RESULTS: All eligible hospices (n=32) completed the online survey. All hospices provided care at home, with 94% (n=30) also providing care for patients in aged residential care facilities. All 32 hospices provided symptom management, family and carer support and bereavement care. Six hospices (19%) did not provide afterhours cover. Fifteen (47%) hospices did not have Maori cultural position and median full time equivalent across all hospices for such position was one day per week. Only nine (28%) hospices provided palliative medicine specialist training. CONCLUSION: Areas of inconsistency were highlighted including afterhours access and cultural support for Maori. The capacity of the present system to address current and future shortages of palliative medicine specialist is questioned.

RESUMO

BACKGROUND: In New Zealand, 34% of deaths occur in the hospital setting where junior doctors are at the frontline of patient care. The death rate in New Zealand is expected to double by 2068 due to the aging population, but many studies report that graduates feel unprepared to care for people near the end of life and find this to be one of the most stressful parts of their work. International guidelines recommend that palliative and end of life care should be a mandatory component of undergraduate medical education, yet teaching varies widely and remains optional in many countries. Little is known about how medical students in New Zealand learn about this important area of clinical practice. The purpose of this study was to investigate the organisation, structure and provision of formal teaching, assessment and clinical learning opportunities in palliative and end of life care for undergraduate medical students in New Zealand. METHODS: Quantitative descriptive, cross-sectional survey of module conveners in New Zealand medical schools. RESULTS: Palliative and end of life care is included in undergraduate teaching in all medical schools. However, there are gaps in content, minimal formal assessment and limited contact with specialist palliative care services. Lack of teaching staff and pressure on curriculum time are the main barriers to further curriculum development. CONCLUSIONS: This article reports the findings of the first national survey of formal teaching, assessment and clinical learning opportunities in palliative and end of life care in undergraduate medical education in New Zealand. There has been significant progress towards integrating this content into the curriculum, although further development is needed to address barriers and maximise learning opportunities to ensure graduates are as well prepared as possible.

RESUMO

Background and study aims This study aimed to assess the quality of endoscopy training in a UK Statutory Educational Body compared with Joint Advisory Group on Gastrointestinal Endoscopy Training standards (JETS). Methods A total of 28,298 training procedures recorded by 211 consecutive cross-specialty trainee endoscopists registered with JETS in 18 hospitals during 2019 were analyzed. Data included trainer and trainee numbers, training list frequency, procedures, direct observation of procedural skills (DOPS) completion, and key performance indicators. Results Annual median training procedures per hospital were 1395 (interquartile range (IQR) 465-2365). Median trainers and trainees per unit were 11 (6-18) and 12 (7-16), respectively, (ratio 0.8 [0.7-1.3]). Annual training list frequency per trainee was 13 (10-17), 35.0 % short of Joint Advisory Group (JAG) standard (n = 20, P = 0.001, effect size -0.56). Median points per adjusted training list were 11 (5-18). Median DOPS per trainee and trainer were three (1-6) and four (1-7) respectively; completing 0.2 DOPS (0.1-0.4) per list and amounting to six (2-12) per 200 procedures: fewer than half of the JAG standard (20 per 200) (P < 0.001, -0.61). Esophagogastroduodenoscopy median KPI: J maneuver 94 % (90-96), D2 intubation 93 % (91-96); Colonoscopy KPI: cecal intubation 82 % (72-90), polyp detection rate 25 % (18-34). Compound hospital score ranged from nine to 26 (median 17 [14-20]). Conclusions Important performance disparity emerged with three-fold variation in compound hospital training quality and most units underperforming compared with JAG standards. Trainees and training program directors should be aware of such metrics to improve quality endoscopy educational programs and consider formal adjuncts to optimize training.

RESUMO

Emotional regulation is increasingly gaining acceptance as a means to improve well-being, performance, and leadership across high-stakes professions, representing innovation in thinking within the field of surgical education. As one part of a broader cognitive skill set that can be trained and honed, emotional regulation has a strong evidence base in high-stress, high-performance fields. Nevertheless, even as Program Directors and surgical educators have become increasingly aware of this data, with emerging evidence in the surgical education literature supporting efficacy, hurdles to sustainable implementation exist. In this white paper, we present evidence supporting the value of emotional regulation training in surgery and share case studies in order to illustrate practical steps for the development, adaptation, and implementation of emotional regulation curricula in three key developmental contexts: basic cognitive skills training, technical skills acquisition and performance, and preparation for independence. We focus on the practical aspects of each case to elucidate the challenges and opportunities of introducing and adopting a curricular innovation into surgical education. We propose an integrated curriculum consisting of all three applied contexts for emotional regulation skills and advocate for the dissemination of such a longitudinal curriculum on a national level.

RESUMO

INTRODUCTION: Surgical career progression is determined by examination success and Annual Review of Competence Progression (ARCP) outcome, yet data on organisational skills are sparse. This study aimed to determine whether organisational skills related to Core Surgical Training (CST) outcome. Primary outcome measures include operative experience, publications, examination success (Membership of the Royal College of Surgeons or the Diploma in Otolaryngology-Head and Neck Surgery (MRCS/DO-HNS)) and ARCP outcome. METHODS: The study was conducted prospectively at three consecutive CST induction boot camps (2017-2019) providing clinical and simulation training for 125 trainees. Arrival time at course registration was the selected surrogate for organisational skills. Trainees were advised to arrive promptly at 8:45 for registration and that the course would start at 9:00. Trainee arrival times were grouped as follows: early (before 8:45), on time (8:45-8:59am) or late (after 9:00). Arrival times were compared with primary outcome measures. SETTING: Health Education and Improvement Wales' School of Surgery, UK. RESULTS: Median arrival time was 8:53 (range 7:55-10:03), with 29 trainees (23.2%) arriving early, 63 (50.4%) on-time and 33 (26.4%) late. Arrival time was associated with operative experience (early vs late; 206 vs 164 cases, p=0.012), publication (63.2% vs 18.5%, p=0.005), MRCS/DO-HNS success (44.8% vs 15.2%, p=0.029), ARCP outcome (86.2% vs 60.6% Outcome 1, p=0.053), but not National Training Number success (60.0% vs 53.3%, p=0.772). CONCLUSIONS: Better-prepared trainees achieved 25% more operative experience, were four-fold more likely to publish and pass MRCS, which aligned with consistent desirable ARCP outcome. Timely arrival at training events represents a skills-composite of travel planning and is a useful marker of strategic organisational skills.

RESUMO

OBJECTIVES: To compare proportional representation of healthcare specialty workers, in receipt of New Year Honours (NYHs) and examine system bias. DESIGN: Observational study of UK honours system including comparative analysis of proportional representation of the UK medical workforce. PARTICIPANTS: Recipients of NYHs from 2010 to 2019. MAIN OUTCOME MEASURES: Absolute risk of receiving an NYH, related to medical specialty, gender and geographical region. Relative risk (RR) of receiving an NYH for services to healthcare related to specialty. RESULTS: 11 207 NYHs were bestowed, with 368 (3.3%) awarded to healthcare professionals: 212 (57.6%) women, 156 (42.4%) men. The RR of a healthcare professional receiving an NYH was 0.76 (95% CI 0.68 to 0.84, p<0.001) when compared with the remaining UK workforce. Doctors received most NYHs (n=181), with public health, clinical oncology and general medicine specialties most likely to be rewarded (RR 20.35 (95% CI 9.61 to 43.08, p<0.001), 8.43 (95% CI 2.70 to 26.30, p<0.001) and 8.22 (95% CI 6.22 to 10.86, p<0.001)), respectively; anaesthetists received fewest NYHs (RR 0.52 (95% CI 0.13 to 2.10), p=0.305). Men were more likely to receive NYHs than women (OR 0.44, 95% CI 0.36 to 0.54; p<0.001). Two hundred and fifty-four NYHs (69.0%) were bestowed on residents of England (60, 16.3% London), 49 (13.3%) Scotland (p=0.003), 39 (10.6%) Wales (p<0.001) and 26 (7.1%) Northern-Ireland (p<0.001). CONCLUSIONS: Relative risk of receiving an NYH varied over 150-fold by specialty, twofold by gender and threefold by geographical location. Public health physicians are perceived to be the pick of the parade.

RESUMO

This study aimed to analyse the degree of relative variation in speciality-specific competencies required for Certification of Completion of Training (CCT) set by the UK Joint Committee for Surgical Training (JCST) 2021 curriculum. Regulatory body guidance related to operative and non-operative surgical skill competencies required for CCT were analysed and compared. Wide inter-speciality variation was demonstrated in the minimum number of logbook cases (median 815; range 54 to 2100), indexed operations (8; 5 to 24) and procedure-based assessments (35; 6 to 110). Academic competencies related to peer-reviewed publications, communications to learned societies and audits were aligned at zero, zero and three across specialities, respectively. Mandatory courses have been standardised with Advanced Trauma Life Support being the sole pre-requisite CCT for all. JCST certification guidelines have broadly standardised competency domains, yet large discrepancies persist regarding operative indicative numbers and assessments. This article serves as a definitive CCT guide regarding prevailing changes.

RESUMO

Graves' disease (GD) is an autoimmune disease caused by antibodies to the thyroid stimulating hormone receptor (TSHR). The FDA-cleared Thyretain™ TSI bioassay is a highly specific method to detect thyroid stimulating antibodies (TSAb/TSI) in the blood of patients with autoimmune thyroid disease (AITD), particularly GD. To simplify the workflow of this bioassay and to support a semi-quantitative result, we have generated a stable CHO-K1 cell line expressing both a chimeric TSH receptor (TSHR-Mc4) and a luciferase-based homogeneous cAMP biosensor (GS luciferase). Here, we describe a rapid, real-time, homogenous bioassay (Turbo™ TSI Bioassay) to directly assess the functional activity of TSI and produce results in International Units of IU/L. The Turbo™ TSI bioassay works by measuring changes in the intracellular cAMP level induced by a G-protein coupled receptor (G-PCR) signaling cascade which is triggered by the binding of TSI to the TSHR. Upon binding to cAMP, the GS luciferase reporter is activated through conformational changes and generates light that can be measured in intact cells with a luminometer. The LoD and LoQ of the assay were determined to be 0.016 IU/L and 0.03 IU/L, respectively and the preliminary assay cutoff was determined to be 0.024 IU/L by ROC analysis using the Thyretain™ TSI bioassay results as reference. The analytical performance of the Turbo™ TSI bioassay is comparable to the Thyretain™ TSI bioassay as evidenced by similar EC50 values for a TSHR stimulating monoclonal antibody (M22). The specificity of the Turbo™ TSI bioassay was demonstrated by showing no response to a high concentration of a human monoclonal TSHR blocking antibody (K1-70). The precision of the assay was excellent with an overall within-laboratory precision <15% CV. When testing 198 clinical samples, the positive and negative percent agreement between the Turbo™ TSI and the Thyretain™ TSI bioassays were 98.7% and 93.5%, respectively. While both bioassays yield equivalent analytical and clinical performances, the Turbo™ TSI bioassay is much simpler to perform. It does not require cell culture, sample dilution, washing or cell lysis steps, resulting in a dramatically reduced turnaround time from about 21 h to 60 min. In addition, the same cell line showed its capability of detecting thyroid blocking antibodies (TBAb/TBI) in a competitive format. The Turbo™ TSI bioassay is user-friendly and is a very promising advancement to aid the diagnosis of autoimmune thyroid disease (AITD).

RESUMO

BACKGROUND: A competition ratio (CR) indicates the ratio of total applications for a training post when compared with numbers of specialty posts available. This study aimed to evaluate CRs' influence on National Training Number (NTN) selection in a single UK Statutory Education Body. METHODS: Consecutive core surgical trainees numbering 154 (105 men, 49 women; median years since graduation: four) were studied over a 6-year period. Annual specialty specific CRs were obtained from Health Education England's website, and primary outcome measure was UK NTN appointment. RESULTS: Overall NTN appointment was 45.5%. Median CR was 2.36; range Oral & Maxillofacial Surgery 0.70 (2020) to Neurosurgery 22.0 (2020). Multivariable analysis revealed that NTN success was associated with: CR (OR 0.46, p=0.003), a single scientific publication (OR 6.25, p=0.001), cohort year (2019, OR 12.65, p=0.003) and Universal Annual Review of Competence Progression Outcome 1 (OR 45.24, p<0.001). CRs predicted NTN appointment with a Youden index defined critical ratio of 4.42; 28.6% (n=8) versus 49.2% (n=62), p=0.018. CONCLUSION: CRs displayed 30-fold variation, with CRs below 4.42 associated with twofold better NTN promotion, but strong clinical competence and academic reach again emerged as the principal drivers of career advancement.
