Creation and Adoption of Large Language Models in Medicine.

Importance: There is increased interest in and potential benefits from using large language models (LLMs) in medicine. However, by simply wondering how the LLMs and the applications powered by them will reshape medicine instead of getting actively involved, the agency in shaping how these tools can be used in medicine is lost. Observations: Applications powered by LLMs are increasingly used to perform medical tasks without the underlying language model being trained on medical records and without verifying their purported benefit in performing those tasks. Conclusions and Relevance: The creation and use of LLMs in medicine need to be actively shaped by provisioning relevant training data, specifying the desired benefits, and evaluating the benefits via testing in real-world deployments.

Integrating Client Tracker Tool Into Fistula Management: Experience From the Fistula Care Plus Project in the Democratic Republic of Congo, 2017 to 2019.

This study aimed to document the experience of integration and the contribution of the Client Tracker (CT) to female genital fistula (FGF) management and data quality in sites supported by the Fistula Care+ Project in the Democratic Republic of Congo (DRC), from 2017 to 2019. It was a parallel mixed methods study using routine quantitative data and qualitative data from in-depth interviews with the project staff. Quantitative findings indicated that CT forms were present in the medical records of 63% of patients; of these, 38% were completely filled out, and 29% were correctly filled out. Qualitative findings suggested that the level of use of CT in the management of FGF was associated with staff familiarity with the CT, staff understanding of concepts in the CT forms, and the CT-related additional workload. The CT has mainly contributed to improving data quality and reporting, quality of care, follow-up of fistula patients, and self-supervision of management activities. A possible simplification of the CT and/or harmonization of its content with existing routine forms, coupled with adequate continuous training of staff on record-keeping, would further contribute to maximizing CT effectiveness and sustainability.

Optimal Method for Reporting Prostate Cancer Grade in MRI-targeted Biopsies.

When multiple cores are biopsied from a single magnetic resonance imaging (MRI)-targeted lesion, Gleason grade may be assigned for each core separately or for all cores of the lesion in aggregate. Because of the potential for disparate grades, an optimal method for pathology reporting MRI lesion grade awaits validation. We examined our institutional experience on the concordance of biopsy grade with subsequent radical prostatectomy (RP) grade of targeted lesions when grade is determined on individual versus aggregate core basis. For 317 patients (with 367 lesions) who underwent MRI-targeted biopsy followed by RP, targeted lesion grade was assigned as (1) global Grade Group (GG), aggregated positive cores; (2) highest GG (highest grade in single biopsy core); and (3) largest volume GG (grade in the core with longest cancer linear length). The 3 biopsy grades were compared (equivalence, upgrade, or downgrade) with the final grade of the lesion in the RP, using κ and weighted κ coefficients. The biopsy global, highest, and largest GGs were the same as the final RP GG in 73%, 68%, 62% cases, respectively (weighted κ: 0.77, 0.79, and 0.71). For cases where the targeted lesion biopsy grade scores differed from each other when assigned by global, highest, and largest GG, the concordance with the targeted lesion RP GG was 69%, 52%, 31% for biopsy global, highest, and largest GGs tumors (weighted κ: 0.65, 0.68, 0.59). Overall, global, highest, and largest GG of the targeted biopsy show substantial agreement with RP-targeted lesion GG, however targeted global GG yields slightly better agreement than either targeted highest or largest GG. This becomes more apparent in nearly one third of cases when each of the 3 targeted lesion level biopsy scores differ. These results support the use of global (aggregate) GG for reporting of MRI lesion-targeted biopsies, while further validations are awaited.

How to Take a Good Clinical History in Cases of Allergic Reactions to Medications

The clinical history is the cornerstone of the doctor's work. When assessing patients consulting for a suspected hypersensitivity reactionto a drug, the details collected in the patient's clinical history are essential when deciding which tests to perform and for makingrecommendations about which drugs the patient should avoid and which can be taken. This area is especially important today, since manypatients are labeled as allergic to drugs, especially penicillins, without this being the case. This article reviews the importance of the clinicalhistory in a patient with a hypersensitivity reaction to a drug and considers which data should be collected. Likewise, a record-based modelis proposed to help standardize the clinical history (AU)

La historia clínica es la piedra angular del trabajo del médico. En el estudio de los pacientes que consultan por una supuesta reacción dehipersensibilidad a un fármaco, los detalles recogidos en la historia clínica del paciente son fundamentales para decidir el estudio quehay que realizar y para, al final, dar recomendaciones al paciente sobre los fármacos que debe evitar o que puede tomar. Actualmentecobra especial importancia este tema, dado que hay un elevado porcentaje de la población que, sin serlo, está etiquetada de alergiaa fármacos, sobre todo a las penicilinas. En este artículo se revisa la importancia que tiene la historia clínica ante un paciente con unareacción de hipersensibilidad a un fármaco y qué datos deben ser recogidos. Asimismo, se propone un modelo de ficha que puede ayudara la estandarización de la historia clínica (AU)

Dor e fatores associados em pacientes atendidos em um serviço de urgência odontológica no sul do Brasil / Pain and associated factors in patients attending an emergency dental service in southern Brazil

O objetivo deste estudo transversal foi avaliaro desfecho dor e fatores associados em pacientes atendidos em um serviço de urgência odontológica no sul do Brasil. Foram avaliados 137 prontuários provenientes de um projeto de extensão para capacitação em atendimento odontológico de urgência da Universidade Federal de Santa Maria (Santa Maria/RS), referentes ao período de abril de 2017 a dezembro de 2018. Os dados contidos na ficha clínica, autorrelatados pelos pacientes, foram coletados e variáveis relacionadas às características socioeconômicas, médicas e odontológicas foram submetidas à análise estatística descritiva e regressão de Poisson multivariada. A prevalência de dor nestes pacientes foi de 65,2%e a hipótese diagnósticamais prevalente foi de pulpite aguda irreversível (46,2% dos casos). A procura por atendimento foi maiorna faixa etária entre 40-59 anos (48,6%), no sexo feminino (64%), em pacientes sem nível superior (85,3%) e os dentes mais frequentemente tratados foram os posteriores (82,7%). Houve associação entre a presença de dor e variáveis médicas, sendo queos pacientes com mais de duas doençassistêmicas apresentaram maior prevalência de dor. O preenchimento inadequado dos prontuários odontológicos foi um achado comum, o que pode prejudicar o estabelecimento do perfil epidemiológico destes pacientes e o planejamento dos atendimentos futuros de forma eficiente, além de poder acarretar problemas jurídicos (AU).

This cross-sectional study aimed to evaluate the pain outcome and associated factorsin patients attending an emergency dental service in southern Brazil. One hundred and thirty-seven (137) patient records from an extension project for emergency dental care training at the Universidade Federal de Santa Maria (Santa Maria, RS, Brazil), relative to the period from April 2017 to December 2018, were evaluated. The data in the records, self-reported by the patients, were collected, and variables related to socioeconomic, medical and dental characteristics were subjected to descriptive statistical analysis and multivariate Poisson regression. The prevalence of pain in these patients was 65.2%, and the most prevalent diagnostic hypothesis was irreversible acute pulpitis (46.2% of the cases). The demand for care was greater in the age group between40-59 years (48.6%), in women (64%), in patients without university education (85.3%), and posterior teeth were the most frequently treated (82.7%). There was an association between the presence of pain and medical variables, being that patients with morethan two systemic diseases had a higher prevalence of pain. The inadequate completion of dental records was a common finding, which can impair the establishment of the epidemiological profile of these patients and the efficient planning of future dental care services, as well as cause legal problems (AU).

Study protocol for WHO and UNICEF estimates of global, regional, and national preterm birth rates for 2010 to 2019.

BACKGROUND: Preterm birth is a leading cause of death among children under five years. Previous estimates indicated global preterm birth rate of 10.6% (14.8 million neonates) in 2014. We aim to update preterm birth estimates at global, regional, and national levels for the period 2010 to 2019. METHODS: Preterm birth is defined as a live birth occurring before 37 completed gestational weeks, or <259 days since a woman's last menstrual period. National administrative data sources for WHO Member States with facility birth rates of ≥80% in the most recent year for which data is available will be searched. Administrative data identified for these countries will be considered if ≥80% of UN estimated live births include gestational age information to define preterm birth. For countries without eligible administrative data, a systematic review of studies will be conducted. Research studies will be eligible if the reported outcome is derived from an observational or intervention study conducted at national or sub-national level in population- or facility-based settings. Risk of bias assessments will focus on gestational age measurement method and coverage, and inclusion of special subgroups in published estimates. Covariates for inclusion will be selected a priori based on a conceptual framework of plausible associations with preterm birth, data availability, and quality of covariate data across many countries and years. Global, regional and national preterm birth rates will be estimated using a Bayesian multilevel-mixed regression model. DISCUSSION: Accurate measurement of preterm birth is challenging in many countries given incomplete or unavailable data from national administrative sources, compounded by limited gestational age assessment during pregnancy to define preterm birth. Up-to-date modelled estimates will be an important resource to measure the global burden of preterm birth and to inform policies and programs especially in settings with a high burden of neonatal mortality.

Structured Reporting of Computed Tomography Examinations in Post-Lung Transplantation Patients.

OBJECTIVE: The aim of this study was to evaluate the benefits and potential of structured reports (SR) for chest computed tomography after lung transplantation. METHODS: Free-text reports (FTR) and SR were generated for 49 computed tomography scans. Clinical routine reports were used as FTR. Two pulmonologists rated formal aspects, completeness, clinical utility, and overall quality. Wilcoxon and McNemar tests were used for statistical analysis. RESULTS: Structured reports received significantly higher ratings for all formals aspects (P < 0.001, respectively). Completeness was higher in SR with regard to evaluation of bronchiectases, bronchial anastomoses, bronchiolitic and fibrotic changes (P < 0.001, respectively), and air trapping (P = 0.012), but not signs of pneumonia (P = 0.5). Clinical utility and overall quality were rated significantly higher for SR than FTR (P < 0.001, respectively). However, report type did not influence initiation of further diagnostic or therapeutic measures (P = 0.307 and 1.0). CONCLUSIONS: Structured reports are superior to FTR with regard to formal aspects, completeness, clinical utility, and overall satisfaction of referring pulmonologists.

Modifying phrases in surgical pathology reports: introduction of Standardized Scheme of Reporting Certainty in Pathology Reports (SSRC-Path).

Pathologists often incorporate modifying phrases in their diagnosis to imply varying levels of diagnostic certainty; however, what is implied by the pathologists is not equivalent with what is perceived by the referring physicians and patients. This discordance can have significant implications in management, safety, and cost. We intend to identify lack of consistency in interpretation of modifying phrases by comparing perceived level of certainty by pathologists and non-pathologists, and introduce a standard scheme for reporting uncertainty in pathology reports using the experience with imaging reporting and data systems. In this study, a list of 18 most commonly used modifying phrases in pathology reports was distributed among separate cohorts of pathologists (N = 17) and non-pathology clinicians (N = 225) as a questionnaire survey, and the participants were asked to assign a certainty level to each phrase. All the participants had practice privileges in Brown University-affiliated teaching hospitals. The survey was completed by 207 participants (17 pathologists, 190 non-pathologists). It reveals a significant discordance between the interpretations of the modifying phrases between the two cohorts, with significant variations in subgroups of non-pathology clinicians. Also there is disagreement between pathologists and other clinicians regarding the causes of miscommunication triggered by pathology reports. Pathologists and non-pathology clinicians should be mindful of the potential sources of misunderstanding of pathology reports and take necessary actions to prevent and clarify the uncertainties. Using a standard scheme for reporting uncertainty in pathology reports is recommended.

Facilitating better postnatal care with women-held documents in The Gambia: a mixed-methods study.

BACKGROUND: Women-held documents are a basic component of continuity of maternity care. The use and completion of women-held documents following discharge could improve treatment and care for postnatal women. Using a mixed-methods study design, we aimed to assess the number, type, quality and completeness of women-held discharge documents, identify factors contributing to document completeness and facilitators or barriers for effective use of the documents. METHODS: Documents given to women at discharge from three hospitals in the Greater Banjul Area, The Gambia, were reviewed for content and quality. All women completed a questionnaire on the use of the documents. Poisson regression was used to estimate factors predicting document completion. Semi-structured interviews (n = 21) and focus groups (n = 2) were carried out with healthcare professionals (HCPs). RESULTS: Nearly all (n = 211/212; 99%) women were given a document to take home. The most complete document (maternal record) had on average 17/26 (65%) items completed and 10% of women held an illegible document. None of the women's sociodemographic or clinical characteristics predicted document completeness. The following facilitators for effective use of documents were identified from the women's responses to the questionnaire and interviews with HCPs: 94% of women thought written information is important, 99% plan to have postnatal check-ups and 67% plan to use their documents, HCPs understand the importance of the documents and were familiar with the document's use and content. The following barriers for effective use of documents were identified: HCPs had too many women-held documents to complete at discharge, there is no national protocol and HCPs think women do not understand the documents due to a lack of education and that women often lose or forget their documents. CONCLUSIONS: Women-held documents are well established in The Gambia; though quality and completeness needs improving. Future research should determine the impact of using only one document at discharge, protocols and training on completeness, among other outcomes, and on ways to ensure all women are using the documents for their postnatal care.

Validity of chemotherapy information derived from routinely collected healthcare data: A national cohort study of colon cancer patients.

BACKGROUND: We used a structured approach to validate chemotherapy information derived from a national routinely collected chemotherapy dataset and from national administrative hospital data. METHODS: 10,280 patients who had surgical resection with stage III colon cancer were included. First, we compared information derived from the national chemotherapy dataset (SACT) and from the administrative hospital dataset (HES) in the English NHS with respect to receipt of adjuvant chemotherapy (ACT). Second, we compared regimen and number of cycles in linked patient-level records. Third, we carried out a sensitivity analysis to establish to what extent the impact of ACT receipt differed according to data source. RESULTS: 6,012 patients (58 %) received ACT according to either dataset. Of these patients, 3,460 (58 %) had ACT records in both datasets, 1,649 (27 %) in SACT alone, and 903 (15 %) in HES alone. Of the 3,460 patients with records in both datasets, 3,320 (96 %) had matching regimens. There was good agreement on cycle number with similar proportions of patients recorded with a single cycle (6 % in SACT vs. 7 % in HES) and slightly fewer patients recorded with more than 8 cycles in SACT (32 % in SACT vs. 35 % in HES). 3-year cancer-specific mortality was similar for patients receiving ACT, regardless of whether a patient received ACT according to SACT alone (16.6 %), according to HES alone (16.8 %), or according to either SACT or HES (17.1 %). CONCLUSION: Routinely collected national chemotherapy data and administrative hospital data are highly accurate in recording regimen and number of chemotherapy cycles. However, chemotherapy information should ideally be captured from both datasets to avoid under-capture, particularly of oral chemotherapy from administrative hospital data, and to minimise bias.

Not discussed: Inequalities in narrative text data for suicide deaths in the National Violent Death Reporting System.

BACKGROUND: The rate of suicide in the US has increased substantially in the past two decades, and new insights are needed to support prevention efforts. The National Violent Death Reporting System (NVDRS), the nation's most comprehensive registry of suicide mortality, has qualitative text narratives that describe salient circumstances of these deaths. These texts have great potential for providing novel insights about suicide risk but may be subject to information bias. OBJECTIVE: To examine the relationship between decedent characteristics and the presence and length of NVDRS text narratives (separately for coroner/medical examiner (C/ME) and law enforcement (LE) reports) among 233,108 suicide and undetermined deaths from 2003-2017. METHODS: Generalized estimating equations (GEE) logistic and quasi-Poisson modeling was used to examine variation in the narratives (proportion of missing texts and character length of the non-missing texts, respectively) as a function of decedent age, sex, race/ethnicity, education, marital status, military history, and homeless status. Models adjusted for site, year, location of death, and autopsy status. RESULTS: The frequency of missing narratives was higher for LE vs. C/ME texts (19.8% vs. 5.2%). Decedent characteristics were not consistently associated with missing text across the two types of narratives (i.e., Black decedents were more likely to be missing the LE narrative but less likely to be missing the C/ME narrative relative to non-Hispanic whites). Conditional on having a narrative, C/ME were significantly longer than LE (822.44 vs. 780.68 characters). Decedents who were older, male, had less education and some racial/ethnic minority groups had shorter narratives (both C/ME and LE) than younger, female, more educated, and non-Hispanic white decedents. CONCLUSION: Decedent characteristics are significantly related to the presence and length of narrative texts for suicide and undetermined deaths in the NVDRS. Findings can inform future research using these data to identify novel determinants of suicide mortality.

Retention of patient-held medical records for chronic diseases in Mozambique.

INTRODUCTION: Non-Communicable Diseases (NCD) are becoming a public health problem in Mozambique and wider sub-Saharan Africa, and are driving changes to guaranty lifelong follow up of patients within the health systems. Patient-Held Medical Records (PHMR) are an option for this follow-up in under-resourced health systems. We designed a study to assess the rate of retention and quality of conservation of the PHMR. METHODS: we conducted a prospective observational study from November 2016 to October 2018 in a peri-urban hospital from in Mozambique. Consecutive newly diagnosed patients with cardiovascular disease were given PHMR. Data was collected after their first consultation and one year after. The retention and quality of conservation were assessed after 12 months. RESULTS: overall 134 PHMR were given to patients (24;17.9% children and 77;57.5% female), of which 121 (90.3%) retained at 12 months (90.9% in good conservation state). Most patients had on average four visits to health facilities during the study, all registered in the PHMR. Retention could not be confirmed in 13 patients who did not return the PHMR. CONCLUSION: PHMR retention rates were high in an urban low-income setting in Africa, with high quality of conservation, thus supporting its use to replace hospital paper-based medical files. Specific research is recommended on acceptability, quality of information registered and patient´s perception.
