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.

Assessing the Quality of Medical and Health Data From the 2003 Birth Certificate Revision: Results From New York City.

Objectives-A primary goal of the 2003 revision of the U.S. Standard Certificate of Live Birth was to improve data quality.This report evaluates the quality of selected 2003 revision-based medical and health data by comparing birth certificate data for New York City with information abstracted from hospital medical records.Methods-A random sample of records for 900 births occurring in New York City in 2013 was reviewed. Birth certificate and hospital medical records data were compared for these categories: pregnancy history, prenatal care, gestational age, birthweight, pregnancy risk factors, source of payment, characteristics of labor and delivery, fetal presentation, method of delivery, abnormal conditions of the newborn, infant living, and infant breastfed. Levels of missing data, exact agreement, kappa scores, sensitivity, and false discovery rates are presented where applicable. Results-Exact agreement or sensitivity between birth certificate and medical record data was high (90.0% or greater) for a number of items (e.g., number of previous cesarean deliveries, cephalic presentation, cesarean delivery, vaginal/spontaneous delivery, obstetric estimate of gestation [within 2 weeks], Medicaid as source of payment for the delivery, birthweight [within 500 grams]), but extremely low (less than 40.0%) for several items (e.g., gestational hypertension, previous preterm birth, augmentation of labor, assisted ventilation, maternal transfusion). Levels of agreement or sensitivity for several items (e.g., obstetric estimate of gestation at delivery [exact number of weeks], previous cesarean delivery, private insurance as the source of payment for delivery, and total number of prenatal care visits [within two visits]), were substantial (between 75.0% and 89.9%) or moderate (between 60.0% and 74.9%). Data quality often varied by hospital.

New blood donors in times of crisis: Increased donation willingness, particularly among people at high risk for attracting SARS-CoV-2.

BACKGROUND: Traditionally, during crises the number of new blood donors increases. However, the current coronavirus disease 2019 (COVID-19) pandemic created additional barriers to donate due to governmental prevention measures and increased personal health risks. In this report, we examined how the pandemic affected new donor registrations in the Netherlands, especially among groups with higher risk profiles for severe COVID-19. Additionally, we explored the role of media for blood donation and new donor registrations. STUDY DESIGN AND METHODS: We analyzed new donor registrations and attention for blood donation in newspapers and on social media from January until May 2020, in comparison to the same period in 2017 to 2019. RESULTS: After the introduction of nationwide prevention measures, several peaks in new donor registrations occurred, which coincided with peaks in media attention. Interestingly, people with a higher risk profile for COVID-19 (e.g., due to age or region of residence) were overrepresented among new registrants. DISCUSSION: In sum, the first peak of the current pandemic has led to increased new blood donor registrations, despite the associated increased health risks. Time and future studies will have to tell whether these new donors are one-off 'pandemic' donors or if they will become regular, loyal donors.

A small pilot study to evaluate the accuracy and feasibility of a novel automated voiding diary device for recording urine output measurements.

AIMS: Recording a voiding diary can be bothersome for patients and is sometimes inaccurate and unhygienic. This study aimed to develop and assess the accuracy and convenience of a novel device that automatically records the voiding diary by measuring pre- and post-void body weight. METHODS: We used this novel device for seven healthy volunteers and ten hospitalized patients. The examinees got on the device before and after voiding and the device recorded the voiding diary automatically. The examinees also manually recorded a voiding diary by collecting their urine in a cup and measuring its volume and weight. We examined the correlation between the traditional and the automated voiding diary to confirm the accuracy of voiding measurements using this device. Additionally, we investigated which measurement method was preferred by the participants. RESULTS: In the healthy volunteers group, there was a strong correlation between the voided urine weight recorded by the device and voided urine weight measured manually by the examinee (R2 = 0.9935). In the patients group, there was a strong (R2 = 0.9117) but lower correlation than that of the volunteers group, with an error of ±25 g 62% of the time, and ±50 g 82% of the time, respectively. All of the healthy volunteers and seven of the ten patients preferred using the automated voiding diary. CONCLUSIONS: This novel device recorded a reasonably accurate voiding diary for everyday clinical practice.

Using a Daily Diary Approach to Examine Substance Use and Negative Sexual Experiences Among College Students.

This article examined substance use and sexual behavior by conducting an analysis of college students' reported behaviors using a daily diary approach. By isolating particular sexual events across a 2-month period, we examined situational predictors of engagement in sex and of negative sexual experiences (coerced sex and/or sex that lacks perceived control) for college men and women. Data come from the daily diary sub-study of the Sexual Health Initiative to Foster Transformation. These data include 60 days of daily responses from 420 undergraduates at one New York City institution. This was a relatively diverse sample comprised of 49% women, 28% identifying as non-heterosexual, 60% non-white, and a roughly equal number of college freshman, sophomores, juniors, and seniors. Analyses examined the effects of alcohol use, binge drinking, marijuana use, and other drug use on sexual experiences. Between-person and within-person substance uses were related to an increased likelihood of having at least one sexual encounter during the study period. After adjusting for each participants' average substance use, both the number of alcoholic drinks consumed (AOR 1.13 (1.05-1.21)) and binge drinking scores (AOR 2.04 (1.10-3.79)) increased the likelihood of negative sex. Interaction analyses showed that compared to men, women were more likely to use alcohol and marijuana prior to sexual encounters. Given that sex and substance use are co-occurring, current prevention approaches should be paired with strategies that attempt to prevent negative sexual experiences, including sexual assault, more directly. These include consent education, bystander training, augmentation of sexual refusal skills, and structural change. Efforts promoting increased sex positivity might also help make all students, and women in particular, less likely to use substances in order to facilitate sex.

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.

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.

Structured reporting of brain MRI following mechanical thrombectomy in acute ischemic stroke patients.

BACKGROUND: To compare the quality of free-text reports (FTR) and structured reports (SR) of brain magnetic resonance imaging (MRI) examinations in patients following mechanical thrombectomy for acute stroke treatment. METHODS: A template for SR of brain MRI examinations based on decision trees was designed and developed in house and applied to twenty patients with acute ischemic stroke in addition to FTR. Two experienced stroke neurologists independently evaluated the quality of FTR and SR regarding clarity, content, presence of key features, information extraction, and overall report quality. The statistical analysis for the differences between FTR and SR was performed using the Mann-Whitney U-test or the Chi-squared test. RESULTS: Clarity (p < 0.001), comprehensibility (p < 0.001), inclusion of relevant findings (p = 0.016), structure (p = 0.005), and satisfaction with the content of the report for immediate patient management (p < 0.001) were evaluated significantly superior for the SR by both neurologist raters. One rater additionally found the explanation of the patient's clinical symptoms (p = 0.003), completeness (p < 0.009) and length (p < 0.001) of SR to be significantly superior compared to FTR and stated that there remained no open questions, requiring further consultation of the radiologist (p < 0.001). Both neurologists preferred SR over FTR. CONCLUSIONS: The use of SR for brain magnetic resonance imaging may increase the report quality and satisfaction of the referring physicians in acute ischemic stroke patients following mechanical thrombectomy. Trial registration Retrospectively registered.

The accuracy of administrative health data for identifying patients with rheumatoid arthritis: a retrospective validation study using medical records in Western Australia.

The use of administrative health datasets is increasingly important for research on disease trends and outcome. The Western Australian (WA) Rheumatic Disease Epidemiological Registry contains longitudinal health data for over 10,000 patients with rheumatoid arthritis (RA). Accurate coding for RA is essential to the validity of this dataset. Investigate the diagnostic accuracy of International Classification of Diseases (ICD)-based discharge codes for RA at WA's largest tertiary hospital. Medical records for a sample of randomly selected patients with ICD-10 codes (M05.00-M06.99) in the hospital discharge database between 2008 and 2020 were retrospectively reviewed. Rheumatologist-reported diagnoses and ACR/EULAR classification criteria were used as reference standards to determine accuracy measures. Medical chart review was completed for 87 patients (mean (± SD) age 64.7 ± 17.2 years), 67.8% female). A total of 80 (91.9%) patients had specialist confirmed RA diagnosis, while seven patients (8%) had alternate clinical diagnoses. Among 87 patients, 69 patients (79.3%) were fulfilled ACR/EULAR classification criteria. The agreement between the reference standards was moderate (Kappa 0.41). Based on rheumatologist-reported diagnoses and ACR/EULAR classification criteria, primary diagnostic codes for RA alone had a sensitivity of (90% vs 89.8%), and PPV (90.9% vs 63.6%), respectively. A combination of a diagnostic RA code with biologic infusion codes in two or more codes increased the PPV to 97.9%. Hospital discharge diagnostic codes in WA identify RA patients with a high degree of accuracy. Combining a primary diagnostic code for RA with biological infusion codes can further increase the PPV.

Evaluation of Radiology Reports by the Emergency Department Clinical Providers: A Message to Radiologists [Formula: see text].

OBJECTIVES: This study is an evaluation of the emergency department (ED) satisfaction with the current radiologic reporting system used at a major Northeastern academic medical center. The radiology reports are the main form of communication and usually the final product of any radiological investigation delivered to clinicians. The aim of this study was to improve current radiology reporting practices and to better tailor reports to match the needs and expectations of ED clinicians. METHODS: A 9-question online survey was sent to ED residents, fellows, faculty, and nurse practitioners/advanced practice providers at a major Northeastern academic medical center in the United States. For the open-ended section, coding and emergent theme categorization was conducted for quantification of responses. The survey was designed to evaluate the attitudes toward the structure, style, form, and wording used in reports. RESULTS: The response rate was 48.6% (68/140). The ED respondents were generally satisfied with radiology reports, their language, vocabulary, and clarity. They preferred the impression section to be before the findings in simple examinations and to stratify the reports according to emergency status for complex examinations. They did not like extended differential, hedge terms, and delayed reporting. Additionally, ED respondents recommended focused, fast reporting with considerable changes toward a more standardized report. CONCLUSIONS: This evaluation delivered a list of actionable recommendations. The top recommendation is to standardize reporting structure, style, and lexicon, in addition to being focused, timely, and brief.

Cardiac Arrest and Cardiopulmonary Resuscitation Outcome Reports: Update of the Utstein Resuscitation Registry Template for In-Hospital Cardiac Arrest: A Consensus Report From a Task Force of the International Liaison Committee on Resuscitation (American Heart Association, European Resuscitation Council, Australian and New Zealand Council on Resuscitation, Heart and Stroke Foundation of Canada, InterAmerican Heart Foundation, Resuscitation Council of Southern Africa, Resuscitation Council of Asia).

Utstein-style reporting templates provide a structured framework with which to compare systems of care for cardiac arrest. The 2004 Utstein reporting template encompassed both out-of-hospital and in-hospital cardiac arrest. A 2015 update of the Utstein template focused on out-of-hospital cardiac arrest, which makes this update of the in-hospital template timely. Representatives of the International Liaison Committee on Resuscitation developed an updated in-hospital Utstein reporting template iteratively by meeting face-to-face, by teleconference, and by online surveys between 2013 and 2018. Data elements were grouped by hospital factors, patient variables, pre-event factors, cardiac arrest and postresuscitation processes, and outcomes. Elements were classified as core or supplemental by use of a modified Delphi process. Variables were described as core if they were considered essential. Core variables should enable reasonable comparisons between systems and are considered essential for quality improvement programs. Together with core variables, supplementary variables are considered useful for research.

Detection of Deteriorating Patients on Surgical Wards Outside the ICU by an Automated MEWS-Based Early Warning System With Paging Functionality.

BACKGROUND: The establishment of early warning systems in hospitals was strongly recommended in recent guidelines to detect deteriorating patients early and direct them to adequate care. Upon reaching predefined trigger criteria, Medical Emergency Teams (MET) should be notified and directed to these patients. The present study analyses the effect of introducing an automated multiparameter early warning score (MEWS)-based early warning system with paging functionality on 2 wards hosting patients recovering from highly complex surgical interventions. METHODS: The deployment of the system was accompanied by retrospective data acquisition during 12 months (intervention) using 4 routine databases: Hospital patient data management, anesthesia database, local data of the German Resuscitation Registry, and measurement logs of the deployed system (intervention period only). A retrospective 12-month data review using the same aforementioned databases before the deployment of the system served as control. Control and intervention phases were separated by a 6-month washout period for the installation of the system and for training. RESULTS: Data from 3827 patients could be acquired from 2 surgical wards during the two 12-month periods, 1896 patients in the control and 1931 in the intervention cohorts. Patient characteristics differed between the 2 observation phases. American Society of Anesthesiologists risk classification and duration of surgery as well as German DRG case-weight were significantly higher in the intervention period. However, the rate of cardiac arrests significantly dropped from 5.3 to 2.1 per 1000 admissions in the intervention period (P < 0.001). This observation was paralleled by a reduction of unplanned ICU admissions from 3.6% to 3.0% (P < 0.001), and an increase of notifications of critical conditions to the ward surgeon. The primary triggers for MET activation were abnormal ECG alerts, specifically asystole (n = 5), and pulseless electric activity (n = 8). CONCLUSION: In concert with a well-trained and organized MET, the early deterioration detection of patients on surgical wards outside the ICU may be improved by introducing an automated MEWS-based early warning system with paging functionality.

Classification and reporting guidelines for the pathology diagnosis of placenta accreta spectrum (PAS) disorders: recommendations from an expert panel.

The terminology and diagnostic criteria presently used by pathologists to report invasive placentation is inconsistent and does not reflect current knowledge of the pathogenesis of the disease or the needs of the clinical care team. A consensus panel was convened to recommend terminology and reporting elements unified across the spectrum of PAS specimens (i.e., delivered placenta, total or partial hysterectomy with or without extrauterine tissues, curetting for retained products of conception). The proposed nomenclature under the umbrella diagnosis of placenta accreta spectrum (PAS) replaces the traditional categorical terminology (placenta accreta, increta, percreta) with a descriptive grading system that parallels the guidelines endorsed by the International Federation of Gynaecology and Obstetrics (FIGO). In addition, the nomenclature for hysterectomy specimens is separated from that for delivered placentas. The goal for each element in the system of nomenclature was to provide diagnostic criteria and guidelines for expected use in clinical practice.

Accuracy of Blood Transfusion Records in a Population-based Perinatal Data Registry.

BACKGROUND: Blood transfusion is frequently used as an indicator of severe maternal morbidity during pregnancy. However, few studies have examined its validity in population perinatal databases. METHODS: We linked a perinatal database from British Columbia, Canada, with the province's Central Transfusion Registry for 2004-2015 deliveries. Using the Central Transfusion Registry records for red blood cell transfusion as the gold standard, we calculated the sensitivity, specificity, positive predictive value, and negative predictive value of the perinatal database variable for red blood cell transfusion, overall and by transfusion risk factor status. We used multivariable logistic regression to examine whether outcome misclassification altered the odds ratios for different transfusion risk factors. RESULTS: Among 473,688 deliveries, 4,033 (8.5 per 1,000) had a red blood cell transfusion according to the Central Transfusion Registry. The sensitivity of the perinatal database transfusion variable was 72.3 [95% confidence interval (CI) = 72.2, 72.4]. Sensitivity differed according to the presence of many transfusion risk factors (e.g., 84.9% vs. 72.2% in deliveries with versus without uterine rupture). Odds ratios associated with some transfusion risk factors were exaggerated when the perinatal database transfusion variable was used to define the outcome instead of the Central Transfusion Registry variable, but 95% confidence intervals for these estimates overlapped. CONCLUSION: Blood transfusion was documented with reasonable sensitivity in this large population perinatal database. However, validity varied according to risk factor status. Our findings enable researchers to better account for outcome misclassification in studies of obstetrical transfusion risk factors.

Development and initial validation of the bronchiectasis exacerbation and symptom tool (BEST).

BACKGROUND: Recurrent bronchiectasis exacerbations are related to deterioration of lung function, progression of the disease, impairment of quality of life, and to an increased mortality. Improved detection of exacerbations has been accomplished in chronic obstructive pulmonary disease through the use of patient completed diaries. These tools may enhance exacerbation reporting and identification. The aim of this study was to develop a novel symptom diary for bronchiectasis symptom burden and detection of exacerbations, named the BEST diary. METHODS: Prospective observational study of patients with bronchiectasis conducted at Ninewells Hospital, Dundee. We included patients with confirmed bronchiectasis by computed tomography, who were symptomatic and had at least 1 documented exacerbation of bronchiectasis in the previous 12 months to participate. Symptoms were recorded daily in a diary incorporating cough, sputum volume, sputum colour, dyspnoea, fatigue and systemic disturbance scored from 0 to 26. RESULTS: Twenty-one patients were included in the study. We identified 29 reported (treated exacerbations) and 23 unreported (untreated) exacerbations over 6-month follow-up. The BEST diary score showed a good correlation with the established and validated questionnaires and measures of health status (COPD Assessment Test, r = 0.61, p = 0.0037, Leicester Cough Questionnaire, r = - 0.52,p = 0.0015, St Georges Respiratory Questionnaire, r = 0.61,p < 0.0001 and 6 min walk test, r = - 0.46,p = 0.037). The mean BEST score at baseline was 7.1 points (SD 2.2). The peak symptom score during exacerbation was a mean of 16.4 (3.1), and the change from baseline to exacerbation was a mean of 9.1 points (SD 2.5). Mean duration of exacerbations based on time for a return to baseline symptoms was 15.3 days (SD 5.7). A minimum clinically important difference of 4 points is proposed. CONCLUSIONS: The BEST symptom diary has shown concurrent validity with current health questionnaires and is responsive at onset and recovery from exacerbation. The BEST diary may be useful to detect and characterise exacerbations in bronchiectasis clinical trials.

Characterizing female patients with haemophilia A: Administrative claims analysis and medical chart review.

AIM: Haemophilia A (HA) is a male-predominant disorder, yet women and girls can have factor VIII (FVIII) deficiency with bleeding events requiring treatment. This study aimed to identify and characterize female patients with HA. METHODS: Administrative claims dated 01 January 2012-31 July 2016 were accessed for patients with 18 months' coverage by commercial or Medicare Advantage with Part D insurance. Patients were included by HA diagnoses or treatments and/or bleeding-related diagnoses or procedures, and excluded by haemophilia B or qualitative platelet disorder diagnoses. A sample of charts was examined for bleeding history, HA therapies and bleeding treatments. All-cause healthcare utilization and costs were also described. RESULTS: Among 353 patients meeting initial inclusion criteria, 86 charts were procured, with 8 patients identified as having HA. Their mean age was 60 ± 17 years and most were Medicare-insured. The mean Charlson Comorbidity Index score was 2.50 ± 2.56; the most prevalent comorbid conditions involved coagulation/haemorrhage, fluid/electrolyte balance and non-traumatic joint disorders. Over 18 months, a mean of 54 ambulatory visits and 120 pharmacy fills were observed; mean medical costs were $86 694 and pharmacy costs were $25 396. CONCLUSIONS: Identifying females with HA is challenging using healthcare claims, because diagnostic nomenclature is unclear for female patients treated for bleeding events. Although chart abstraction enhanced claims data, very few female patients were identified with HA. Nevertheless, even in a small sample, sizeable burden in comorbidity and healthcare use was observed. Improved nomenclature and coding for HA diagnoses for women and girls is key to improving research and treatment.

Hiding in plain sight-unreported osteoporotic vertebral fractures.

KEY POINTS: • Reporting of vertebral fractures has important clinical consequences and can be improved by routinely performing sagittal reformating and by the use of a standard nomenclature and classification.

Radiology reporting of osteoporotic vertebral fragility fractures on computed tomography studies: results of a UK national audit.

OBJECTIVES: To evaluate organisational reporting infrastructure and patient-related reporting data in the diagnosis of vertebral fragility fractures (VFFs) as demonstrated on computed tomography (CT). METHODS: Organisational and patient-specific questionnaires were developed by consensus between The Royal College of Radiologists, the Royal College of Physicians, and the Royal Osteoporosis Society. The patient-specific component of the audit involved analysis of CT reporting data acquired from 50 consecutive non-traumatic studies including the thoracolumbar spine. Ethical approval for this type of study is not required in the UK. All UK radiology departments with an audit lead (auditor) registered with The Royal College of Radiologists (RCR) were invited to participate in this retrospective audit. RESULTS: In total, 127 out of 202 departments (63%) supplied data to the study, with inclusion of 6357 patients. Overall, 1362/6357 patients (21.4%) had a fracture present on auditor review of the CT imaging. There was a lack of compliance with all audit standards: 79% of reports commented on the vertebrae (target 100%), fracture severity was mentioned in 26.2% (target 100%), the recommended terminology 'vertebral fracture' was used in 60.1% (target 100%), and appropriate onward referral was recommended in 2.6% (target 100%). CONCLUSIONS: The findings from this study should be used to provide impetus to improve the diagnosis and care for patients with osteoporotic VFFs. Solutions are multifactorial, but radiologist and local osteoporosis/fracture liaison service engagement is fundamental, combined with necessary development of electronic report notification systems and expansion of supporting fracture services. KEY POINTS: • Early detection and diagnosis of vertebral fragility fractures (VFFs) significantly reduce patient morbidity and mortality. This study describes the results of a retrospective UK-wide audit evaluating current radiology reporting practice in the opportunistic diagnosis of VFFs as demonstrated on computed tomography (CT) studies including the spine. • Key audit standards included comment made on bone integrity in primary report (target 100%), comment made on severity of fractures (90%), report used recommended terminology 'fracture' (100%), and report made appropriate recommendations for referral/further assessment (100%). The audit results demonstrated a lack of compliance with all audit standards; lack of compliance was most marked in the use of recommended terminology (achieved 60.3%), in relation to comment on fracture severity (achieved 26.2%) and for recommendation for referral/further assessment (achieved 2.6%). • Solutions are challenging and multifactorial but the opportunity exists for all radiologists to examine their practice and directly improve patient care.

Validity and reliability of subjective methods to assess sedentary behaviour in adults: a systematic review and meta-analysis.

BACKGROUND: Subjective measures of sedentary behaviour (SB) (i.e. questionnaires and diaries/logs) are widely implemented, and can be useful for capturing type and context of SBs. However, little is known about comparative validity and reliability. The aim of this systematic review and meta-analysis was to: 1) identify subjective methods to assess overall, domain- and behaviour-specific SB, and 2) examine the validity and reliability of these methods. METHODS: The databases MEDLINE, EMBASE and SPORTDiscus were searched up to March 2020. Inclusion criteria were: 1) assessment of SB, 2) evaluation of subjective measurement tools, 3) being performed in healthy adults, 4) manuscript written in English, and 5) paper was peer-reviewed. Data of validity and/or reliability measurements was extracted from included studies and a meta-analysis using random effects was performed to assess the pooled correlation coefficients of the validity. RESULTS: The systematic search resulted in 2423 hits. After excluding duplicates and screening on title and abstract, 82 studies were included with 75 self-reported measurement tools. There was wide variability in the measurement properties and quality of the studies. The criterion validity varied between poor-to-excellent (correlation coefficient [R] range - 0.01- 0.90) with logs/diaries (R = 0.63 [95%CI 0.48-0.78]) showing higher criterion validity compared to questionnaires (R = 0.35 [95%CI 0.32-0.39]). Furthermore, correlation coefficients of single- and multiple-item questionnaires were comparable (1-item R = 0.34; 2-to-9-items R = 0.35; ≥10-items R = 0.37). The reliability of SB measures was moderate-to-good, with the quality of these studies being mostly fair-to-good. CONCLUSION: Logs and diaries are recommended to validly and reliably assess self-reported SB. However, due to time and resources constraints, 1-item questionnaires may be preferred to subjectively assess SB in large-scale observations when showing similar validity and reliability compared to longer questionnaires.

Health care professionals' adherence to partograph use in Ethiopia: analysis of 2016 national emergency obstetric and newborn care survey.

BACKGROUND: The period around childbirth and the first 24 hours postpartum remains a perilous time for both mother and newborn. Health care providers' compliance to the World Health Organization modified partogram across the active first stage of labor is a graphic representation of a mother's condition that is used as a guide in providing quality obstetrics care. However, little evidence is documented on the health providers' adherence to the use of the partograph in Ethiopia, which limits health care providers' ability to improve quality care services. Therefore, this study assessed the adherence of partograph use and associated factors in Ethiopia. METHODS: Data from the Ethiopian 2016 National Emergency Obstetric and Newborn Care survey of 3,804 health facilities that provided maternity services were used. We extracted 2611 partograph charts over a 12 months period prior to the survey to review the proper recording of each component. Data analyses were performed using SPSS version 22.0 software. A logistic regression analyses was used to identify the association of explanatory variables with the outcome variable. A p-value of <0.05 was considered as cut off point to declare the significance association in the multivariable analysis. RESULTS: Of the total 2611 partographs reviewed, 561(21.5%) of them were fully recorded as per the WHO guideline. Particularly, molding in 50%, color of liquor in 70.5%, fetal heart beat in 93.3%, cervical dilation in 89.6%, descent in 63.2%, uterine contraction in 94.5%, blood pressure in 80.5%, pulse rate in 70.5%, and temperature in 53% were accurately recorded. The odds of adherence to partograph use were 1.4 in rural health facilities when compared to their counterparts (AOR=1.44; 95% CI: 1.15, 1.80, P- 0.002). CONCLUSION: This study revealed a poor level of adherence in partograph use in Ethiopia. Molding, maternal temperature and decent were the least recorded parameters of the partograph. The odds of completion of partograph were high in rural facilities. Strong supporting supervision and mentoring the health workers to better record and use of partograph are needed mainly in urban health facilities. Moreover in the future, interventional research should be conducted to improve the current rate of adherence.
