Survival from lung cancer remains low, yet is the most common cancer diagnosed worldwide. With survival contrasting between the main histological groupings, small-cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), it is important to assess the extent that geographical differences could be from varying proportions of cancers with unspecified histology across countries. Lung cancer cases diagnosed 2010-2014, followed until 31 December 2015 were provided by cancer registries from seven countries for the ICBP SURVMARK-2 project. Multiple imputation was used to reassign cases with unspecified histology into SCLC, NSCLC and other. One-year and three-year age-standardised net survival were estimated by histology, sex, age group and country. In all, 404 617 lung cancer cases were included, of which 47 533 (11.7%) and 262 040 (64.8%) were SCLC and NSCLC. The proportion of unspecified cases varied, from 11.2% (Denmark) to 29.0% (The United Kingdom). After imputation with unspecified histology, survival variations remained: 1-year SCLC survival ranged from 28.0% (New Zealand) to 35.6% (Australia) NSCLC survival from 39.4% (The United Kingdom) to 49.5% (Australia). The largest survival change after imputation was for 1-year NSCLC (4.9 percentage point decrease). Similar variations were observed for 3-year survival. The oldest age group had lowest survival and largest decline after imputation. International variations in SCLC and NSCLC survival are only partially attributable to differences in the distribution of unspecified histology. While it is important that registries and clinicians aim to improve completeness in classifying cancers, it is likely that other factors play a larger role, including underlying risk factors, stage, comorbidity and care management which warrants investigation.

BACKGROUND: Preoperative goals of care (GOC) and code status (CS) discussions are important in achieving an in-depth understanding of the patient's care goals in the setting of a serious illness, enabling the clinician to ensure patient autonomy and shared decision making. Past studies have shown that anesthesiologists are not formally trained in leading these discussions and may lack the necessary skill set. We created an innovative online video curriculum designed to teach these skills. This curriculum was compared to a traditional method of learning from reading the medical literature. METHODS: In this bi-institutional randomized controlled trial at 2 major academic medical centers, 60 anesthesiology trainees were randomized to receive the educational content in 1 of 2 formats: (1) the novel video curriculum (video group) or (2) journal articles (reading group). Thirty residents were assigned to the experimental video curriculum group, and 30 were assigned to the reading group. The content incorporated into the 2 formats focused on general preoperative evaluation of patients and communication strategies pertaining to GOC and CS discussions. Residents in both groups underwent a pre- and postintervention objective structured clinical examination (OSCE) with standardized patients. Both OSCEs were scored using the same 24-point rubric. Score changes between the 2 OSCEs were examined using linear regression, and interrater reliability was assessed using weighted Cohen's kappa. RESULTS: Residents receiving the video curriculum performed significantly better overall on the OSCE encounter, with a mean score of 4.19 compared to 3.79 in the reading group. The video curriculum group also demonstrated statistically significant increased scores on 8 of 24 rubric categories when compared to the reading group. CONCLUSIONS: Our novel video curriculum led to significant increases in resident performance during simulated GOC discussions and modest increases during CS discussions. Further development and refinement of this curriculum are warranted.

BACKGROUND: Emergency general surgery (EGS) encompasses a heterogeneous population of acutely ill patients, and standardized methods for determining disease severity are essential for comparative effectiveness research and quality improvement initiatives. The American Association for the Surgery of Trauma (AAST) has developed a grading system for the anatomic severity of 16 EGS conditions; however, little is known regarding how well these AAST EGS grades can be approximated by diagnosis codes in administrative databases. METHODS: We identified adults admitted for 16 common EGS conditions in the 2012 to 2017q3 National Inpatient Sample. Disease severity strata were assigned using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes based on AAST EGS anatomic severity grades. We evaluated whether assigned EGS severity (multiple strata or dichotomized into less versus more complex) were associated with in-hospital mortality, complications, length of stay, discharge disposition, and costs. Analyses were adjusted for age, sex, comorbidities, hospital traits, geography, and year. RESULTS: We identified 10,886,822 EGS admissions. The number of anatomic severity strata derived from ICD-9/10-CM codes varied by EGS condition and by year. Four conditions mapped to four strata across all years. Two conditions mapped to four strata with ICD-9-CM codes but only two or three strata with ICD-10-CM codes. Others mapped to three or fewer strata. When dichotomized into less versus more complex disease, patients with more complex disease had worse outcomes across all 16 conditions. The addition of multiple strata beyond a binary measure of complex disease, however, showed inconsistent results. CONCLUSION: Classification of common EGS conditions according to anatomic severity is feasible with International Classification of Diseases codes. No condition mapped to five distinct severity grades, and the relationship between increasing grade and outcomes was not consistent across conditions. However, a standardized measure of severity, even if just dichotomized into less versus more complex, can inform ongoing efforts aimed at optimizing outcomes for EGS patients across the nation. LEVEL OF EVIDENCE: Prognostic, level III.

BACKGROUND: Emerging data indicate a resurgence of availability and harms of amphetamine-type stimulant (ATS) use. This study examined ATS overdose-involved emergency department (ED) visit trends and visit characteristics associated with ATS overdose. METHODS: Data from the Healthcare Cost and Utilization Project's (HCUP) 2010-2017 Nationwide Emergency Department Sample identified ATS overdose-involved visits. Predicted trend lines from 2010 to 2015 were fit using weighted logistic regression forany or only ATS-involved overdose using ICD-9-CM discharge diagnosis codes; percentage change from 2016 to 2017 used ICD-10-CM. Multivariable logistic regression examined characteristics in 2017 associated with only ATS-involved overdoses compared to drug overdoses not involving ATS. RESULTS: Every year from 2010 to 2015 the odds of any ATS overdose-involved ED visits increased 11 % (odds ratio [OR]: 1.11, 95 % CI: 1.09, 1.14) and 7 % for only ATS overdose-involved visits (OR: 1.07, 95 % CI: 1.04, 1.10). From 2016 to 2017, any and only ATS overdose-involved visit rates increased 19.1 % and 20.5 %, respectively (P < .05). In 2017, ATS overdose-involved visits (N = 42,428) accounted for 4.4 % of all drug overdose visits (N = 956,266). In adjusted regression models, characteristics more prevalent among patients with only ATS overdose included Western region; micropolitan and noncore urbanization levels; unintentional, undetermined, and assault intents; and cardiovascular effects. CONCLUSIONS: Our findings, coupled with the rising availability of ATS and related harms, underscore the expansion of current substance use and overdose prevention and response efforts to address stimulant use, particularly among groups at risk. Research to identify additional individual and community-level risk factors for increasing ATS overdose is warranted.

In the International Classification of Diseases, 10th Revision (ICD-10) two opposing principles are combined and mixed: atheoreticity that is necessary for the natural classification and commitment to nosology. Implementation of these principles requires a two-stage qualification. The first stage should be narrative detailed syndromological qualifications with identification of psychotic level of disorders. As for the second stage, the qualification should be nosological, based on complete clinical analysis, which is far from being possible to realize at once. ICD-10, specifically brought to nosological certainty, may remain the natural foundation for nosological qualification. Implementation of the syndromic qualification at the first stage will allow to consider nosological features of each syndrome at the second stage and to expand the list of criteria in different clusters. Such a suggestion opens the prospect for subsequent revisions of the ICD and allows to direct our efforts and those of practitioners to the unified channel, where the statistical goals would not be implemented at the expense of the research ones.

In everyday clinical work, psychiatrists encounter patients who present with symptoms spanning several diagnostic categories, e.g., showing signs of a psychosis, depression, and anxiety. This raises the critical question of which symptoms hold precedence over other and, by extension, which diagnosis is the right diagnosis. ICD-10 and DSM-5 do not provide unambiguous answers to this question and therefore psychiatry remains exposed to diagnostic disagreement with consequences for treatment and research. We explored symptom distribution in a sample of 98 first-admission psychiatric patients. We extracted and categorized singular symptoms into symptom domains: anxiety, mania, delusions, hallucinations, first-rank symptoms, and negative symptoms. Most symptoms were seen in most disorders. We found symptoms of depression and anxiety in almost all patients. Thus, just counting symptoms do not seem to be a valid way to make diagnoses. We elaborately discuss these issues in the context of the differential-diagnosis between schizophrenia and depression. Finally, we suggest that a combination of a criteria- and Gestalt-based approach to diagnosing mental disorders may contribute to counteract some of the current differential-diagnostic confusion.

BACKGROUND: Previous research to describe the impact of foot involvement in psoriatic arthritis has used the Leeds Foot Impact Scale in Rheumatoid Arthritis (LFIS-RA) in the current absence of any psoriatic arthritis foot-specific tools. However, the LFIS-RA is a rheumatoid arthritis disease-specific outcome measure and its content validity for evaluating the experiences of people with psoriatic arthritis-related foot involvement is unknown. The study objective was to determine the content validity of the LFIS-RA for assessing people with psoriatic arthritis, using the International Classification of Functioning, Disability and Health (ICF) as the frame of reference. METHOD: Concepts within each item of the LFIS-RA were linked to the best-matched ICF categories using established linking rules, which enable a systematic and standardised linking process. All concepts were independently linked to the ICF by 2 investigators with different professional backgrounds, which included occupational therapy and podiatry. The list of ICF categories derived from previous research that pertained to the foot in psoriatic arthritis was then compared with the ICF categories linked to the LFIS-RA. The comparison was undertaken in order to determine the extent to which concepts important and relevant to people with psoriatic arthritis-related foot involvement were addressed. RESULTS: Thirty-five distinct ICF categories were linked to the LFIS-RA, which related to body functions (44%), activities and participation (35%), environmental factors (16%) and body structure (5%). In comparison with the ICF categories derived from concepts of the foot in psoriatic arthritis previously defined, the LFIS-RA provided coverage of key constructs including pain, functioning, daily activities, footwear restrictions and psychological impact. Other concepts of importance in psoriatic arthritis such as skin and toenail involvement, self-management and paid employment were not addressed in the LFIS-RA. CONCLUSION: Content validity of the LFIS-RA to determine the impact of foot functional impairments and disability in people with psoriatic arthritis was not supported by the results of this study. Future work should consider the development of a psoriatic arthritis foot-specific patient reported outcome measure, using the LFIS-RA as an important foundation.

This article provides a brief overview of the changes from ICD-10 to ICD-11 regarding the classification of mental, behavioral, or neurodevelopmental disorders. These changes include a new chapter structure, new diagnostic categories, changes in diagnostic criteria, and steps towards dimensionality. Additionally, we review evaluative field studies of ICD-11, which provide preliminary evidence for higher reliability and clinical utility of ICD-11 compared with ICD-10. Despite the extensive revision process, changes from ICD-10 to ICD-11 were relatively modest in that both systems are categorical, classifying mental phenomena based on self-reported or clinically observable symptoms. Other recent approaches to psychiatric nosology and classification (eg, neurobiology-based or hierarchical) are discussed. To meet the needs of different user groups, we propose expanding the stepwise approach to diagnosis introduced for some diagnostic categories in ICD-11, which includes categorical and dimensional elements.â©.
Este artículo entrega una breve descripción de los cambios de la CIE-10 a la CIE-11 con respecto a la clasificación de los trastornos mentales, conductuales o trastornos del neurodesarrollo. Estos cambios incluyen una nueva estructura del capítulo, nuevas categorías diagnósticas, cambios en los criterios diagnósticos y pasos hacia un enfoque dimensional. Además, se revisan los estudios de campo de evaluación para la CIE-11, que proporcionan evidencia preliminar de una mayor confiabilidad y utilidad clínica de la CIE-11 en comparación con la CIE-10. A pesar del extenso proceso de revisión, los cambios de la CIE-10 a la CIE-11 fueron relativamente pocos en el sentido de que ambos sistemas son categoriales y clasifican los fenómenos mentales en base a síntomas auto-reportados o que sean clínicamente observables. Se discuten otros enfoques recientes de la nosología y de la clasificación psiquiátrica (por ejemplo, basados en la neurobiología o de acuerdo a jerarquías). Para satisfacer las necesidades de diferentes grupos de usuarios, se propone expandir el enfoque gradual del diagnóstico introducido para algunas categorías diagnósticas de la CIE-11, que incluye elementos categoriales y dimensionales.
Cet article propose un aperçu des évolutions entre la CIM-10 et la CIM-11 concernant la classification des troubles mentaux, comportementaux ou neurodéveloppementaux. Un nouveau chapitre, de nouvelles catégories diagnostiques, des critères diagnostiques modifiés et des étapes dimensionnelles ont été ajoutés. De plus, nous examinons les données préliminaires issues d'études de terrain d'évaluation de la CIM-11, en faveur d'une plus grande fiabilité et utilité de cette dernière comparée à la CIM-10. Les modifications de la CIM-10 vers la CIM-11 sont relativement modestes malgré une révision étendue, les deux systèmes restant catégoriels et les troubles mentaux étant classés d'après des symptômes auto-rapportés ou cliniquement observables. Nous analysons d'autres approches récentes de la nosologie et de la classification psychiatriques (selon la neurobiologie ou hiérarchiquement par exemple). Certaines catégories diagnostiques de la CIM-11 pourraient bénéficier selon nous de cette méthode progressive en incluant des éléments catégoriels et dimensionnels.

PURPOSE: The CHA2 DS2 -VaSc and HAS-BLED risk scores are commonly used in the studies of oral anticoagulants (OACs). The best ways to map these scores to the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes is unclear, as is how they perform in various types of OAC users. We aimed to assess the distributions of CHA2 DS2 -VaSc and HAS-BLED scores and C-statistics for outcome prediction in the ICD-10-CM era using different mapping strategies. METHODS: We compared the distributions of CHA2 DS2 -VaSc and HAS-BLED scores from various mapping strategies in atrial fibrillation patients before, during, and after ICD-10-CM transition. We estimated the C-statistics predicting the 90-day risk of hospitalized stroke (for CHA2 DS2 -VaSc) or hospitalized bleeding (for HAS-BLED) in patients identified at least 6 months after the ICD-10-CM transition, overall and by anticoagulant type. RESULTS: Forward-backward mapping produced higher CHA2 DS2 -VaSc and HAS-BLED scores in the ICD-10-CM era compared to the ICD-9-CM era: the mean difference was 0.074 (95% confidence interval 0.064-0.085) for CHA2 DS2 -VaSc and 0.055 (0.048-0.062) for HAS-BLED. Both scores had higher C-statistics in patients taking no OACs (0.697 [0.677-0.717] for CHA2 DS2 -VaSc; 0.719 [0.702-0.737] for HAS-BLED) or direct OACs (0.695 [0.654-0.735] for CHA2 DS2 -VaSc; 0.700 [0.673-0.728] for HAS-BLED) than those taking warfarin (0.655 [0.613-0.697] for CHA2 DS2 -VaSc; 0.663 [0.6320.695] for HAS-BLED). CONCLUSIONS: Existing mapping strategies generally preserved the distributions of CHA2 DS2 -VaSc and HAS-BLED scores after ICD-10-CM transition. Both scores performed better in patients on no OACs or direct OACs than patients on warfarin.

In 2019, the World Health Assembly approved the International Classification of Diseases, 11th Revision (ICD-11), which included a traditional medicine chapter. This means that traditional medicine (TM) is incorporated into the mainstream medicine of the world. For TM to contribute to human health, the role of ICD-11, chapter 26 (ICD-11-26), is important. Since the ICD-11-26 is "a union set of harmonized traditional medicine conditions of the Chinese, Japanese, and Korean classifications," it is advisable to supplement the essential patterns while maintaining the already adopted patterns. The ICD-11-26 was originated from the World Health Organization International Standard Terminologies on Traditional Medicine in the Western Pacific Region (WHO-IST), and the WHO-IST is the world's most authoritative TM standard terminology system with an emphasis on traditional and conventional expression. In addition, it includes patterns that are widely used in TM clinical practice and have representative prescriptions at the same time. Therefore, future revisions of ICD-11-26 should make WHO-IST the main reference. Based on this spirit, this proposed revision is a modification of ICD-11-26's structure, order, and expression (English translation) with more essential patterns.

In China, parents who have lost their only child and remained childless are labelled Shidu () parents. Previous research suggests high levels of psychological distress in this population, yet little is known regarding the prevalence of prolonged grief disorder (PGD) based on the new ICD-11 formulation. The present study examined prevalence rates and associated factors of prolonged grief disorder in this population. 1030 Chinese Shidu parents (381 male, 643 female) who were recruited through convenient sampling completed questionnaires assessing grief severity. Multiple linear regression models were used to examine socio-demographic, loss-related and self-reported number of chronic physical conditions associated with PGD symptoms. Results showed prevalence rate was 35.5% based on the ICD-11 PGD criteria, which was almost twice as that of Prigerson et al. (2009) criteria. Younger age of parents, being a mother, living in a rural place, lower monthly income per capital, shorter time since loss and more comorbid chronic physical conditions were related to severer PGD symptoms. The present findings revealed high rates of PGD experienced by Chinese Shidu parents and identified key risk factors which can be used for future prevention or intervention designs in this population.

INTRODUCTION: ICHD-3 criteria for chronic migraine (CM) include a mixture of migraine and tension-type-like headaches and do not account for patients who have a high frequency of migraine but no other headaches. MATERIALS AND METHODS: Patients from the Danish Headache Center and their relatives with ICHD-3 defined CM were compared with patients with high frequency episodic migraine (HFEM). Danish registries were used to compare the socioeconomic impact in these two groups. A Russian student population was used to determine the generalizability of the number of patients fulfilling CM and the proposed diagnostic criteria for CM. RESULTS: There was no difference in the demographic profile between the two groups in the Danish cohort. The number of lifelong or annual attacks (p > 0.3), comorbid diseases, or self-reported effect of triptans (p = 1) did not differ. HFEM patients purchased more triptans than CM patients (p = 0.01). CM patients received more early pension (p = 0.00135) but did not differ from HFEM patients with regard to sickness benefit (p = 0.207), cash assistance (p = 0.139), or rehabilitation benefit (p = 1). DISCUSSION: Patients with HFEM are comparable to CM patients with regard to chronicity and disability. We therefore suggest classifying CM as ≥ 8 migraine days per month (proposed CM), disregarding the need for ≥ 15 headache days per month. The proposed diagnostic criteria for CM approximately doubled the number of patients with CM in both the Danish and the Russian materials. Extending the definition of CM to include patients with HFEM will ensure that patients with significant disease burden and unmet treatment needs are identified and provided appropriate access to the range of treatment options and resources available to those with CM. CONCLUSION: Patients with migraine on eight or more days but not 15 days with headache a month are as disabled as patients with ICHD-3 defined CM. They should be included in revised diagnostic criteria for chronic migraine.

OBJECTIVE: To conduct a systematic review to describe how administrative health databases have been used to study depression and anxiety in patients with rheumatic diseases and to synthesize the case definitions that have been applied. METHODS: Search strategies to identify articles evaluating depression and anxiety among individuals with rheumatic diseases were employed in Medline, Embase, CINAHL, Cochrane Database of Systematic Reviews, and PsycINFO. Studies included were those using administrative health data and reporting case definitions for depression and anxiety using International Classification of Diseases (ICD) codes. We extracted information on study design and objectives, administrative health database, specific data sources (e.g., inpatient, pharmacy records), ICD codes, operational definitions, and validity of case definitions. RESULTS: Of the 36 studies included in this review, all studies assessed depression, and 13 studies (36.1%) evaluated anxiety. A number of specific ICD-9/10 codes were consistently applied to identify depression and anxiety, but the overall combination of ICD codes and operational definitions varied across studies. Twenty-four studies reported operational definitions, and 19 of these studies (79.2%) combined claims from more than 1 type of administrative data source (e.g., inpatient, outpatient). Validated case definitions were used by 6 studies (16.7%), with sensitivity estimates for depression and anxiety case definitions ranging from 33% to 74% and 42% to 76%, respectively. CONCLUSION: We identified numerous case definitions used to evaluate depression and anxiety among individuals with rheumatic diseases within administrative health databases. Recommendations include using case definitions with demonstrated validity as well as operationalizing case definitions within multiple data sources.

CONTEXT: On October 1, 2015, the United States transitioned from using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) to ICD-10-CM. Continuing to monitor the burden of neonatal abstinence syndrome (NAS) after the transition presently requires use of data dependent on ICD-9-CM coding to enable trend analyses. Little has been published on the validation of using ICD-9-CM codes to identify NAS cases. OBJECTIVE: To assess the validity of hospital discharge data (HDD) from selected Florida hospitals for passive NAS surveillance, based on ICD-9-CM codes, which are used to quantify baseline prevalence of NAS. DESIGN: We reviewed infant and maternal data for all births at 3 Florida hospitals from 2010 to 2011. Potential NAS cases included infants with ICD-9-CM discharge codes 779.5 and/or 760.72 in linked administrative data (ie, HDD linked to vital records) or in unlinked HDD and infants identified through review of neonatal intensive care unit admission logs or inpatient pharmacy records. Confirmed infant cases met 3 clinician-proposed criteria. Sensitivity and positive predictive value were calculated to assess validity for the 2 ICD-9-CM codes, individually and combined. RESULTS: Of 157 confirmed cases, 134 with 779.5 and/or 760.72 codes were captured in linked HDD (sensitivity = 85.4%) and 151 in unlinked HDD (sensitivity = 96.2%). Positive predictive value was 74.9% for linked HDD and 75.5% for unlinked HDD. For either HDD types, the single 779.5 code had the highest positive predictive value (86%), lowest number of false positives, and good to excellent sensitivity. CONCLUSIONS: Passive surveillance using ICD-9-CM code 779.5 in either linked or unlinked HDD identified NAS cases with reasonable validity. Our work supports the use of ICD-9-CM code 779.5 to assess the baseline prevalence of NAS through 2015.

Background: The International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) Injury Severity Score (ICISS) is a risk adjustment model when injuries are recorded using ICD-9-CM coding. The trauma mortality prediction model (TMPM-ICD9) provides better calibration and discrimination compared with ICISS and injury severity score (ISS). Though TMPM-ICD9 is statistically rigorous, it is not precise enough mathematically and has the tendency to overestimate injury severity. The purpose of this study is to develop a new ICD-10-CM injury model which estimates injury severities for every injury in the ICD-10-CM lexicon by a combination of rigorous statistical probit models and mathematical properties and improves the prediction accuracy. Methods: We developed an injury mortality prediction (IMP-ICDX) using data of 794,098 patients admitted to 738 hospitals in the National Trauma Data Bank from 2015 to 2016. Empiric measures of severity for each of the trauma ICD-10-CM codes were estimated using a weighted median death probability (WMDP) measurement and then used as the basis for IMP-ICDX. ISS (version 2005) and the single worst injury (SWI) model were re-estimated. The performance of each of these models was compared by using the area under the receiver operating characteristic (AUC), the Hosmer-Lemeshow (HL) statistic, and the Akaike information criterion statistic. Results: IMP-ICDX exhibits significantly better discrimination (AUCIMP-ICDX, 0.893, and 95% confidence interval (CI), 0.887 to 0.898; AUCISS, 0.853, and 95% CI, 0.846 to 0.860; and AUCSWI, 0.886, and 95% CI, 0.881 to 0.892) and calibration (HLIMP-ICDX, 68, and 95% CI, 36 to 98; HLISS, 252, and 95% CI, 191 to 310; and HLSWI, 92, and 95% CI, 53 to 128) compared with ISS and SWI. All models were improved after the extension of age, gender, and injury mechanism, but the augmented IMP-ICDX still dominated ISS and SWI by every performance. Conclusions: The IMP-ICDX has a better discrimination and calibration compared to ISS. Therefore, we believe that IMP-ICDX could be a new viable trauma research assessment method.
