RESUMO
BACKGROUND: Patient complaints are a perennial challenge faced by health care institutions globally, requiring extensive time and effort from health care workers. Despite these efforts, patient dissatisfaction remains high. Recent studies on the use of large language models (LLMs) such as the GPT models developed by OpenAI in the health care sector have shown great promise, with the ability to provide more detailed and empathetic responses as compared to physicians. LLMs could potentially be used in responding to patient complaints to improve patient satisfaction and complaint response time. OBJECTIVE: This study aims to evaluate the performance of LLMs in addressing patient complaints received by a tertiary health care institution, with the goal of enhancing patient satisfaction. METHODS: Anonymized patient complaint emails and associated responses from the patient relations department were obtained. ChatGPT-4.0 (OpenAI, Inc) was provided with the same complaint email and tasked to generate a response. The complaints and the respective responses were uploaded onto a web-based questionnaire. Respondents were asked to rate both responses on a 10-point Likert scale for 4 items: appropriateness, completeness, empathy, and satisfaction. Participants were also asked to choose a preferred response at the end of each scenario. RESULTS: There was a total of 188 respondents, of which 115 (61.2%) were health care workers. A majority of the respondents, including both health care and non-health care workers, preferred replies from ChatGPT (n=164, 87.2% to n=183, 97.3%). GPT-4.0 responses were rated higher in all 4 assessed items with all median scores of 8 (IQR 7-9) compared to human responses (appropriateness 5, IQR 3-7; empathy 4, IQR 3-6; quality 5, IQR 3-6; satisfaction 5, IQR 3-6; P<.001) and had higher average word counts as compared to human responses (238 vs 76 words). Regression analyses showed that a higher word count was a statistically significant predictor of higher score in all 4 items, with every 1-word increment resulting in an increase in scores of between 0.015 and 0.019 (all P<.001). However, on subgroup analysis by authorship, this only held true for responses written by patient relations department staff and not those generated by ChatGPT which received consistently high scores irrespective of response length. CONCLUSIONS: This study provides significant evidence supporting the effectiveness of LLMs in resolution of patient complaints. ChatGPT demonstrated superiority in terms of response appropriateness, empathy, quality, and overall satisfaction when compared against actual human responses to patient complaints. Future research can be done to measure the degree of improvement that artificial intelligence generated responses can bring in terms of time savings, cost-effectiveness, patient satisfaction, and stress reduction for the health care system.

The aim of this study was to identify the impact of staging on a six-months transition in Ultra-High Risk (UHR) youth. Subjects were enrolled at assessment; evolution was monitored for six months. Clinical determinants (unusual thought content, perceptual abnormalities, cognitive complaint, etc.) were collected. 37 non-psychotic and 39 UHR subjects were included. 13 UHR (35.2 %) experienced psychotic transition, while none of non-psychotic subjects did log-rank p < 0.001. Self-reported cognitive complaint was inversely associated to transition OR 0.13 95 % IC [0.03-0.64]. Unusual Thought Content was associated to psychotic transition 0R 8.57 95 % IC [1.17-63]. Self-reported cognitive complaint could be a protective transition marker in UHR.
RESUMO
Pediatric neurological emergencies are a significant concern, often leading to high rates of admission to pediatric intensive care units and increased mortality rates. In Saudi Arabia, the emergency department (ED) is the main entry point for most patients in the healthcare system. This study aimed to provide a comprehensive overview of pediatric neurology visits to the ED, analyzing patient demographics, clinical presentations, and outcomes. The retrospective study was conducted at a large tertiary care center and examined 960 pediatric patients with neurological emergencies out of 24,088 pediatric ED visits. The study population consisted mainly of male participants (56.5%) and 43.5% female participants, with a mean age of 5.29 ± 4.19 years. School-age children (6-12 years) represented the largest population group (29.1%), and over a third of patients were triaged as 'resuscitation' (n = 332, 34.6%). Seizures (n = 317, 33.0%) and postictal states (n = 187, 19.5%) were the most common reasons for seeking emergency care, accounting for over half of all cases. There were statistically significant differences in provisional diagnosis and chief complaints across different age groups (P >0.001 and P <0.001, respectively). The most common outcome was discharge (n = 558; 58.1%), and the mean length of stay was 10.56 ± 20.33 hours. Neuro-emergencies in pediatrics are a concern and a leading cause of mortality, morbidities, and increased hospital visits. The observed variations in presentation and outcomes across age groups further emphasize the importance of tailored approaches.

OBJECTIVE: Subjective cognitive decline (SCD) refers to self-reported memory loss despite normal cognitive function and is considered a preclinical stage of Alzheimer's disease. This study aimed to examine the mediating effects of depression and Instrumental Activities of Daily Living (IADL) on the association between the scoring of Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and Subjective Cognitive Decline Questionnaire (SCD-Q). METHODS: A sample of 139 community-dwelling older adults aged 65-79 with normal cognitive function completed the SCD-Q, a comprehensive neuropsychological battery, and functional/psychiatric scales. We conducted 1) a correlation analysis between SCD-Q scores and other variables and 2) a path analysis to examine the mediating effects of depression and IADL on the relationship between CDR-SB and SCD-Q. RESULTS: CDR-SB was found to be indirectly associated with SCD-Q, with depressive symptoms mediating this relationship. However, no direct association was observed between SCD-Q and CDR-SB. Additionally, IADL was not associated with SCD-Q and did not mediate the relationship between CDR-SB and SCD-Q. The model fit was acceptable (minimum discrepancy function by degrees of freedom divided [CMIN/DF]=1.585, root mean square error of approximation [RMSEA]=0.065, comparative fit index [CFI]=0.955, Tucker-Lewis index [TLI]=0.939). CONCLUSION: Our results suggest that SCD-Q is influenced by depressive symptoms, but not by IADL. The role of depressive symptoms as a mediator between CDR-SB and SCD-Q indicates that psychological factors may contribute to the perception of SCD. Therefore, interventions targeting depression may mitigate the concerns associated with SCD and reduce feelings of worse performance compared to others of the same age group.
RESUMO
OBJECTIVE: To analyse the litigation trends and the reasons for claims within the specialty of Urology, within the UK National Health Service (NHS), over a 16-year period. MATERIALS AND METHODS: Data were requested from NHS Resolution under the Freedom of Information Act 2000. This included the total number of claims in Urology, the number of these that were successful (settled or closed), and the costs in damages paid out per financial year between 2006 and 2022. A breakdown of the successful claims by their primary cause was also collected. These were coded into the categories: 'non-operative', 'intraoperative', 'postoperative', and 'other'. RESULTS: A total of 4124 litigation claims were made between 2006 and 2022 and 60.9% (2511/4124) of these claims were successful. In all, £145 million (British pounds) was paid out in damages. The number of successful claims increased 2.9-fold from the start to end of this 16-year period, and the costs in damages paid out increased 10-fold. Regarding primary causes for the successful claims, failure or delay in treatment (20.9%, 525/2511), failure or delay in diagnosis (14.5%, 364/2511), and intraoperative problems (9.1%, 229/2511) accounted for the highest proportion. Overall, non-operative causes for successful claims accounted for 73.3% (1840/2511), intraoperative for 20.1% (504/2511), and postoperative for 3.9% (98/2511). CONCLUSIONS: The number of successful urological litigation claims, and their associated costs is rising. The majority are due to non-operative causes, which may be partially explained by NHS waiting lists alongside the effects of the coronavirus disease 2019 (COVID-19) pandemic.
RESUMO
Objective: When chatting, people often forget what they want to say, that is, they suffer from subjective memory complaints (SMCs). This research examines the Association between sleep duration and self-reported SMC in a sample representing the entire United States. Methods: We examined data from 5567 individuals (aged 20-80) who participated in the National Health and Nutrition Examination Survey (2015-2018) to evaluate the association between sleep duration and SMC. Odds ratios (ORs) and a restricted cubic spline (RCS) curve were calculated with multiple logistic regression, and subgroup analysis was performed. Results: Approximately 5.8 % (3 2 3) reported SMC, and most are older people (1 6 3). RCS analysis treating sleep duration as a continuous variable revealed a J-shaped curve association between sleep duration and SMC. Self-reported sleep duration was significantly linked to a 33 % elevated risk of SMC (OR, 1.33; 95 % confidence interval [CI], 1.23-1.43; P < 0.001). In the group analysis, individuals who slept more than 8 h per day had a greater association of experiencing SMC than those who slept for 6-8 h/day (OR, 1.75; 95 % CI, 1.36-2.23; P < 0.001). In the analysis of age groups, the stable association between sleep duration and SMC was observed only in the 60-80 age bracket (OR, 1.59; 95 % CI, 1.09-2.33; P < 0.001). Conclusions: We found that people with self-report sleep duration exceeding 8 h are more likely to experience SMC, especially older adults. Improving sleep health may be an effective strategy for preventing SMC and cognitive impairment.
RESUMO
As propagandas de bebidas alcóolicas, além de serem mais frequentes do que outras mercadorias, também apresentam conteúdo que pode ter papel facilitador no uso dessa substância psicoativa, visto que, na maior parte delas, trazem ideias e sensações de prazer. Por isso, esta pesquisa consistiu na identificação e análise qualitativa de propagandas de cerveja que tiveram alguma denúncia feita ao ou pelo Conselho Nacional de Autorregulamentação Publicitária (Conar), nos últimos cinco anos (2015 a 2020), a partir do levantamento dessas denúncias no site do Conar e, posteriormente, foi realizada análise dos motivos condizentes com o código. Como resultado, constatou-se uma progressão nos alinhamentos entre as denúncias e as decisões, sendo encontrada maior dificuldade no alinhamento da infração em relação ao conteúdo das peças publici-tárias do que em questões técnicas.
Advertisements for alcoholic beverages, in addition to being more frequent than other goods, also present content that can play a role in facilitating the use of this psychoactive substance, since, in most of them, they bring ideas and sensations of pleasure. Therefore, this research consisted of the identification and qualitative analysis of beer advertisements that had any complaints made to or by the National Advertising Self-Regulation Council (Conar), in the last five years (2015 to 2020), based on the survey of these complaints on the website of Conar and, subsequently, an analysis of the reasons consistent with the code was carried out. As a result, there was a progression in the alignments between complaints and decisions, with greater difficulty being found in aligning the infraction in relation to the content of the advertising pieces than in technical issues.

Service failure is bound to happen, but dissatisfaction has always been undermined by scholars previously. The present study investigates dissatisfaction factors in travel decision-making leading towards re-travel intention with the help of the expectancy disconfirmation theory (EDT) model. Moreover, complaint behavior mediates the relationship between dissatisfaction and re-travel intention concerning the factors involved in it. For the findings, 434 real-time responses were collected through an offline survey following the lifetime value (LTV) approach. Kaiser-Meyer-Olkin (KMO) and Bartlett's tests were conducted to test the sphericity of the variables one by one. Furthermore, structural equation modeling (SEM) was implied to test the measurement and structural models. All the hypotheses supported and accepted the proposed research questions. The findings reveal that the dissatisfaction factors, with their interaction terms (transaction-based and experience-based), help study the variable dissatisfaction and its multifaceted concept in travel and tourism literature. Moreover, complaint behavior is identified as a key mediating factor in the relationship between dissatisfaction and re-travel intention, suggesting that commuters' response to dissatisfaction, including complaints, shapes their future re-travel intentions. The theoretical implications of the study are substantial, as it advances our understanding of commuter behavior in the context of public transport travel and tourism. Practically, the findings offer actionable insights for public transport authorities and service providers. Understanding the specific dissatisfaction factors influencing re-travel intention allows for targeted interventions to improve service quality and customer experience. Recognizing the importance of effective complaint management systems can help organizations better address customer grievances and mitigate the negative effects of dissatisfaction on re-travel intention.

INTRODUCTION: Identifying individuals at risk of developing dementia is crucial for early intervention. Mild cognitive impairment (MCI) and subjective memory complaints (SMCs) are considered its preceding stages. This study aimed to assess the utility of functional near-infrared spectroscopy (fNIRS) in identifying individuals with MCI and SMC. METHODS: One hundred fifty-one participants were categorized into normal cognition (NC); amnestic MCI (aMCI); non-amnestic MCI (naMCI); and mild, moderate, and severe SMC groups. Task-related prefrontal hemodynamics were measured using fNIRS during a visual memory span task. RESULTS: Results showed significantly lower oxyhemoglobin (HbO) levels in aMCI, but not in naMCI, compared to the NC. In addition, severe SMC had lower HbO levels than the NC, mild, and moderate SMC. Receiver operating characteristic analysis demonstrated 69.23% and 69.70% accuracy in differentiating aMCI and severe SMC from NC, respectively. DISCUSSION: FNIRS may serve as a potential non-invasive biomarker for early detection of dementia. HIGHLIGHTS: Only amnestic mild cognitive impairment (aMCI), but not non-amnestic MCI, showed lower oxyhemoglobin (HbO) than normal individuals. Reduced HbO was observed in those with severe subjective memory complaints (SMCs) compared to normal cognition (NC), mild, and moderate SMCs. Functional near-infrared spectroscopy measures were associated with performance in memory assessments. Prefrontal hemodynamics could distinguish aMCI and severe SMC from NC.

Past studies have highlighted the lack of independent formal complaint mechanisms as one of the most significant barriers to reporting interpersonal violence (IV) in sport. Some countries have since implemented complaint mechanisms specific to sport settings. Evaluations of similar mechanisms in other sectors could inform the development and implementation of complaint mechanisms for IV in sport. This rapid review included studies inside and outside the sport context to document the characteristics of complaint mechanisms of IV, barriers or limitations related to such mechanisms, and recommendations resulting from their evaluation. Following the Cochrane Rapid Reviews Interim Guidance, six databases were searched for peer-reviewed references in English or French, published between 2012 and 2022, and pertaining to the evaluation of formal reporting mechanisms of IV. The 35 references covered mechanisms mainly targeting IV in general (any type) or sexual violence specifically. Complaint mechanisms varied in scope and as a function of their setting, including work, university, military, and medical. We identified barriers and limitations concerning fear of consequences, lack of knowledge, lack of efficiency, lack of trust, and unsupportive culture. Finally, we documented 18 recommendations to improve complaint mechanisms of IV, spanning four categories: (a) organizational accountability, (b) awareness and accessibility, (c) adapted process, and (d) ongoing evaluation. This rapid review draws recommendations from various research disciplines and types of mechanisms to offer a comprehensive portrait of best practices. The findings show that numerous aspects of complaint mechanisms at multiple levels should be considered when developing and implementing complaint mechanisms of IV.
RESUMO
BACKGROUND: Computed tomography (CT) is frequently performed in the patients who admitted to the emergency department (ED), discharged but returned to ED within 72 h. It is unknown whether the main complaints of patients assist physicians to use CT effectively. This study aimed to find the association between chief complaints and the CT results. METHODS: This three-year retrospective cohort study was conducted in the ED of a tertiary medical center. Adult patients who returned to the ED after the index visit were included from 2019 to 2021. Demographics, pre-existing diseases, chief complaints, and CT region were recorded by independent ED physicians. A logistic regression model with an odds ratio (OR) and 95% confidence interval (CI) was used to determine the relationship between chief complaints and positive CT results. RESULTS: In total, 7,699 patients revisited ED after the index visit; 1,202 (15.6%) received CT. The top chief complaints in patients who received CT were abdominal pain, dizziness, and muscle weakness. Patients with abdominal pain or gastrointestinal symptoms had a significantly higher rate of positive abdominopelvic CT than those without it (OR 2.83, 95% CI 1.98-4.05, p < 0.001), while the central nervous system and cardiopulmonary chief complaints were not associated (or negatively associated) with new positive CT findings. CONCLUSION: Chief complaints of patients on revisit to the ED are associated with different yields of new findings when CT scans of the chest, abdomen and head are performed. Physicians should consider these differential likelihoods of new positive findings based on these data.

OBJECTIVE: The objective of this study was to examine in detail the complaints against veterinarians submitted by pet owners and evaluated by the Turkish Veterinary Medical Association in Türkiye, with the aim to create awareness among Turkish veterinarians about the nature of the complaints and how they might reduce the risk of making medical errors. SAMPLE: 127 files of complaints. METHODS: A total of 127 written complaints from pet owners filed between January 2012 and December 2021 were analyzed. The pet owners' complaints were subjected to a conventional content analysis to identify the primary, secondary, and tertiary themes. Each case was evaluated by a 3-level complaint-coding taxonomy. The first level included 3 domains (themes), namely clinical, management, and relationship, while the second level was ordered in a total of 7 subcategories of complaint types. Thereafter, the third-level minor themes were grouped into related subcategories. RESULTS: From 127 file complaints, 296 specific issues were identified. Of these, 62% were in the clinical domain, 24% in the management domain, and 14% about poor behavior of the attending veterinarians. The most common (43%) complaint was medical errors. CLINICAL RELEVANCE: An increased awareness of common medical errors should be promoted among Turkish veterinarians in order to reduce the risk of negligence and malpractice.

Background Patients often turn to online reviews as a source of information to inform their decisions regarding care. Existing literature has analyzed factors associated with positive online patient ratings among hand and wrist surgeons. However, there is limited in-depth analysis of factors associated with low patient satisfaction for hand and wrist surgeons. The focus of this study is to examine and characterize extremely negative reviews of hand and wrist surgeons on Yelp.com. Methods A search was performed using the keywords "hand surgery" on Yelp.com for eight major metropolitan areas including Washington DC, Dallas, New York, Phoenix, Los Angeles, San Francisco, Boston, and Seattle. Only single-star reviews (out of a possible 5 stars) of hand and wrist surgeons were included. The complaints in the 1-star reviews were then categorized into clinical and nonclinical categories. Result A total of 233 single-star reviews were included for analysis, which resulted in 468 total complaints. Of these complaints, 81 (18.8%) were clinically related and 351 (81.3%) were nonclinical in nature. The most common clinical complaints were for complication (24 complaints, 6%), misdiagnosis (16 complaints, 4%), unclear treatment plan (16 complaints, 4%), and uncontrolled pain (15 complaints, 3%). The most common nonclinical complaints were for physician bedside manner (93 complaints, 22%), financially related (80 complaints, 19%), unprofessional nonclinical staff (61 complaints, 14%), and wait time (46 complaints, 11%). The difference in the number of complaints for surgical and nonsurgical patients was statistically significant ( p < 0.05) for complication and uncontrolled pain. Clinical Relevance Patient satisfaction is dependent on a multitude of clinical and nonclinical factors. An awareness of online physician ratings is essential for hand and wrist surgeons to maintain and improve patient care and patient satisfaction. We believe the results of our study could be used to further improve the quality of care provided by hand and wrist surgeons.
RESUMO
Background: Postoperative nausea and vomiting (PONV) following atrial fibrillation (AF) ablation can cause considerable distress. Aim: Continuous intravenous propofol sedation with adaptive servo-ventilation (ASV) with or without an analgesic, pentazocine, during AF ablation was studied in 272 consecutive patients with paroxysmal, persistent, and long-standing persistent AF. The study objectives were to determine the incidence of PONV after AF ablation and to assess the predictive value of factors for PONV using the area under the receiver operating characteristic curve (AUC). Results: The present sedation maneuver was successfully accomplished with a low incidence of hypotension and without discontinuation of ablation or switching to general anesthesia, while maintaining an acceptable procedural time (102 ± 32 min). The incidence of PONV was 5.5% (15/272). Nausea occurred in nine patients after an average of 4.6 ± 3.5 h (range: 2-12 h) postablation, and vomiting with nausea occurred in six patients after an average of 4.5 ± 3.1 h (range: 1-9 h) postablation. The postablation interval did not differ significantly between the occurrence of nausea and nausea accompanied by vomiting. AUCs based on various factors, including the Apfel score, ranged from 0.55 to 0.67, indicating low accuracy in predicting PONV occurrence. Conclusions: The incidence of PONV after propofol sedation with ASV was the lowest (5.5%) reported to date. Scoring systems, which included the Apfel score, were ineffective in predicting PONV. The low PONV incidence in addition to the efficacy of propofol sedation with ASV revealed the adequacy of this regimen for AF ablation.
RESUMO
The need to grapple with hepatitis C-related stigma and discrimination in Australian health-care settings has been recognised in public policy, and work is underway to address it. But how likely are people to raise a complaint when they experience stigma or discrimination? And how effective and accessible are complaints mechanisms? Given complaint procedures are considered important parts of the delivery of safe and ethical health care, these are important questions that have yet to be substantially explored. Drawing on interviews with people with lived experience of hepatitis C (n = 30), this article considers how affected people feel about complaints processes and the act of complaining. Alongside these perspectives, we discuss complaint mechanisms, and the views of stakeholders who work with hepatitis C-affected communities in policy, health, legal and advocacy roles (n = 30) on the institutional and cultural dynamics of complaint. We draw on Sara Ahmed's Complaint! and Fraser et al.'s work on drug-related stigma to analyse these concerns that have yet to be researched, and argue that the (unlikely) prospect of successful complaint is a key part of the network of forces that perpetuate stigma, discrimination and disadvantage among people who have (lived with) hepatitis C. Although people with lived experience are often powerful advocates and acutely aware of the deficiencies in the quality of their treatment, our interviews suggest that the obstacles they face to accessing health care are seen as commonplace, intractable and insurmountable; and, that mechanisms for addressing them-where they exist at all-treat complaints in narrowly individualising terms and expose complainants to dismissal. Following Ahmed, we call for a 'troubling' of complaints-responding to them not as individual problems but rather as collective, structural concerns, necessitating new approaches.
RESUMO
Resting-state eyes-closed electroencephalographic (rsEEG) alpha rhythms are dominant in posterior cortical areas in healthy adults and are abnormal in subjective memory complaint (SMC) persons with Alzheimer's disease amyloidosis. This exploratory study in 161 SMC participants tested the relationships between those rhythms and seed-based resting-state functional magnetic resonance imaging (rs-fMRI) connectivity between thalamus and visual cortical networks as a function of brain amyloid burden, revealed by positron emission tomography and cognitive reserve, measured by educational attainment. The SMC participants were divided into 4 groups according to 2 factors: Education (Edu+ and Edu-) and Amyloid burden (Amy+ and Amy-). There was a statistical interaction (p < 0.05) between the two factors, and the subgroup analysis using estimated marginal means showed a positive association between the mentioned rs-fMRI connectivity and the posterior rsEEG alpha rhythms in the SMC participants with low brain amyloidosis and high CR (Amy-/Edu+). These results suggest that in SMC persons, early Alzheimer's disease amyloidosis may contrast the beneficial effects of cognitive reserve on neurophysiological oscillatory mechanisms at alpha frequencies and connectivity between the thalamus and visual cortical networks.

ISO 10993-1:2018 describes evaluating the biocompatibility profile of a medical device from a risk-based approach. This standard details the battery of information that should be considered within the assessment of a device, including raw material composition data, manufacturing processes, and endpoint testing. The ISO 10993/18562 series requires worst-case assumptions and exposure scenarios to be used in the evaluation, which may result in an over-estimation of patient safety risk. Currently, biocompatibility assessments evaluate each data set independently, and the consequence of this individualized assessment of exaggerated inputs is potential false alarms regarding patient safety. To evaluate these safety concerns, the ISO standards indicate that professional judgement should be used to estimate patient risk but does not provide guidance on incorporating a holistic review of the data into the risk assessment. Recalibrating these worst-case data to evaluate them in a weight-of-evidence (WoE) approach may provide a more realistic data set to determine actual patient risk. This proposed WoE framework combines understanding data applicability with a method for gauging the strength of data that can provide additional support for the final safety conclusion. Using a WoE framework will allow risk assessors to contextualize the data and utilize it to comprehensively estimate patient safety.

The aim of the present study was to investigate adverse effects of head injury, neck trauma, and chronic noise exposure on the complaint profile in people with Ménière's disease (MD). The study used a retrospective design. Register data of 912 patients with MD from the Finnish Ménière Federation database were studied. The data comprised case histories of traumatic brain injury (TBI), neck trauma and occupational noise exposure, MD specific complaints, impact related questions, and the E-Qol health-related quality of life instrument. TBI was classified based on mild, moderate, and severe categories of transient loss of consciousness (TLoC). The mean age of the participants was 60.2 years, the mean duration of the disease was 12.6 years, and 78.7% were females. Logistic regression analysis, linear correlation, and pairwise comparisons were used in evaluating the associations. 19.2% of the participants with MD had a history of TBI. The phenotype of participants with TBI was associated with frequent vestibular drop attacks (VDA), presyncope, headache-associated vertigo, and a reduction in the E-QoL. Logistic regression analysis explained the variability of mild TBI in 6.8%. A history of neck trauma was present in 10.8% of the participants. Neck trauma associated with vertigo (NTwV) was seen in 47 and not associated with vertigo in 52 participants. The phenotype of NTwV was associated with balance problems, VDA, physical strain-induced vertigo, and hyperacusia. Logistic regression analysis explained 8.7% of the variability of the complaint profile. Occupational noise exposure was recorded in 25.4% of the participants and correlated with the greater impact of tinnitus, hyperacusis, and hearing loss. Neither the frequency, duration, or severity of vertigo or nausea were significantly different between the baseline group and the TBI, NTwV, or noise-exposure groups. The results indicate that TBI and NTwV are common among MD patients and may cause a confounder effect.
RESUMO
INTRODUCTION: International medical graduates (IMGs) account for 41% of the UK doctor's workforce but often work in isolated roles, receive minimal constructive feedback regarding their work and offered limited opportunities for career progression. We conducted a survey researching the views of IMGs or doctors from ethnic minority backgrounds on the support given to them. METHODS: A survey was carried out on physician demographics, grade and date of first NHS appointment, familiarity and support offered in NHS, induction and study leave, Professional and Linguistic Assessments Board exams and General Medical Council (GMC) referrals. It was drafted via surveymonkey.co.uk platform and circulated via relevant closed medical groups. RESULTS: A total of 173 IMGs and 16 British trained doctors (controls) took the survey. In the IMGs first job, there was no dedicated supervisor, mentor, induction, shadowing period and study leave for 56%, 86%, 52%, 59% and 52%, respectively. Suggestions given for improvements included teaching sessions, mentors, work orientation, supernumerary period and paid induction by 80%, 78%, 76%, 61% and 41% respectively. While 59% of participants knew of another IMG referred to the GMC, the primary reasons given were lack of knowledge of NHS, bias, communication difficulties and cultural differences. CONCLUSION: This paper reflects the views of doctors regarding the support given to IMGs during their first NHS appointment and subsequent jobs in the NHS. IMGs require a focused and detailed induction, mentorship, educational and clinical supervision throughout their transition to the NHS.

OBJECTIVE: To identify predictors of chronic rhinosinusitis (CRS) in patients presenting with the chief complaint of nasal allergies. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary care, academic center. METHODS: Clinical and demographic characteristics were collected from participants who were patients presenting with the chief complaint of nasal allergies. From all participants, a 22-item Sinonasal Outcome Test (SNOT-22) was collected, and a modified Lund-Kennedy endoscopy score was calculated from nasal endoscopy. Association was sought between having CRS and variables of clinical and demographic characteristics, SNOT-22, and endoscopy score. RESULTS: A total of 219 patients were recruited and 91.3% were diagnosed with allergic rhinitis; 45.2% were also diagnosed with CRS. Approximately half of the patients with CRS reported no intranasal corticosteroid usage. Having CRS was associated with male sex (odds ratio [OR] = 2.29, 95% confidence interval [CI]: 1.30-4.04, P = .004), endoscopy score (OR = 1.96, 95% CI: 1.59-2.42, P < .001), and the SNOT-22 nasal subdomain score (OR = 1.07, 95% CI: 1.03-1.11, P = .001) related to SNOT-22 items: "need to blow nose," "thick nasal discharge," "sense of taste/smell," and "blockage/congestion of nose." At least moderate (item score ≥3) "blockage/congestion of nose" or "thick nasal discharge," mild "need to blow nose" (item score ≥2) or very mild decreased "sense of taste/smell" (item score ≥1), and any nasal endoscopy findings (endoscopy score ≥1) were statistically significant predictors of CRS. CONCLUSION: Moderate or more severe nasal obstruction or discharge symptoms, any decreased sense of smell/taste, or positive nasal endoscopy findings in patients believing they have allergic rhinitis should prompt further evaluation of CRS to avoid delays in treatment.
