Multimorbidity phenotypes in patients presenting to the emergency department with possible acute coronary syndrome

BackgroundMultimorbidity (> 2 conditions) increases the risk of adverse outcomes and challenges health care systems for patients with acute coronary syndrome (ACS). These complications may be partially attributed to ACS clinical care which is driven by single-disease-based practice guidelines; current guidelines do not consider multimorbidity. ObjectivesTo identify multimorbidity phenotypes (combinations of conditions) with suspected ACS. We hypothesized that: 1) subgroups of patients with similar multimorbidity phenotypes could be identified, 2) classes would differ according to diagnosis, and 3) class membership would differ by sex, age, functional status, family history, and discharge diagnosis. MethodsThis was a secondary analysis of data from a large multi-site clinical study of patients with suspected ACS. Conditions were determined by items on the Charlson Comorbidity Index and the ACS Patient Information Questionnaire. Latent class analysis was used to identify phenotypes. ResultsThe sample (n = 935) was predominantly male (68%) and middle-aged (mean= 59 years). Four multimorbidity phenotypes were identified: 1) high multimorbidity (Class 1) included hyperlipidemia, hypertension (HTN), obesity, diabetes, and respiratory disorders (COPD or asthma); 2) low multimorbidity (Class 2) included only obesity; 3) cardiovascular multimorbidity (Class 3) included HTN, hyperlipidemia, and coronary heart disease; and 4) cardio-oncology multimorbidity (Class 4) included HTN, hyperlipidemia, and cancer. Patients ruled-in for ACS primarily clustered in Classes 3 and 4 (OR 2.82, 95% CI 1.95–4.05, p = 0.001 and OR 1.76, 95% CI 1.13–2.74, p = 0.01). ConclusionIdentifying and understanding multimorbidity phenotypes may assist with risk-stratification and better triage of high-risk patients in the emergency department.

Impact of the COVID-19 Pandemic Crisis on the Health Care System in Less Developed Regions of Poland

Purpose: The aim of the study was to develop a model for assessing the satisfaction of patients of GP practice with access to health services in the Lubelskie Voivodeship, in terms of eliminating inequalities in the quality of these services and developing a scenario for the revitalization of the health care system in relation to the inhabitants of the underdeveloped region in the period after the cessation of pandemic. Design/Methodology/Approach: The research method included developing a research tool in the form of a survey questionnaire, validating the tool, conducting Phase I and II of the survey, and evaluating the performance of the outpatient specialty care subsystem. The analysis of the research results was directed at developing the assumptions of a model for restoring functionality and increasing resilience of the healthcare system. Findings: It was found that the level ofpatient satisfaction with the functioning of the health care system during a pandemic, both in the form of medical tele-consultation and in the form of direct contact with personnel in a health care facility, depends on the age and the level of education. There were no differences in terms of sex and place of residence (town, village). It was also found that the very limited availability of advanced diagnostic methods, showing an unfavorable trend in the period preceding the outbreak of the pandemic, deteriorated further and poses a critical threat to the functioning of the health care system for patients with chronic diseases (oncological, neurodegenerative etc.). Practical Implications: The results of the research will be used to construct a model for the reconstruction and revitalization of the health care system in the Lubelskie Voivodeship after the pandemic. Originality/Value: The study presents results of the current research. The development of the research results will be continued in order to construct a comprehensive model.

Estimation of the Number of Patients With Mitochondrial Diseases: A Descriptive Study Using a Nationwide Database in Japan.

To provide a better healthcare system for patients with mitochondrial diseases, it is important to understand the basic epidemiology of these conditions, including the number of patients affected. However, little information about them has appeared in Japan to date. To gather data of patients with mitochondrial diseases, we estimated the number of patients with mitochondrial diseases from April 2018 through March 2019 using a national Japanese health care claims database, the National Database (NDB). Further, we calculated the prevalence of patients, and sex ratio, age class, and geographical distribution. From April 2018 through March 2019, the number of patients with mitochondrial diseases was 3,629, and the prevalence was 2.9 (95% confidence interval [CI], 2.8-3.0) per 100,000 general population. The ratio of females and males was 53 to 47, and the most frequent age class was 40-49 years old. Tokyo had the greatest number of patients with mitochondrial diseases, at 477, whereas Yamanashi had the fewest, at 13. Kagoshima had the highest prevalence of patients with mitochondrial diseases, 8.4 (95% CI, 7.1-10.0) per 100,000 population, whereas Yamanashi had the lowest, 1.6 (95% CI, 0.8-2.7). The number of patients with mitochondrial diseases estimated by this study, 3,269, was more than double that indicated by the Japanese government. This result may imply that about half of all patients are overlooked for reasons such as low severity of illness, suggesting that the Japanese healthcare system needs to provide additional support for these patients.

The Demographics and Epidemiology of Infantile, Juvenile, and Adolescent Idiopathic Scoliosis in a Southern California Integrated Health Care System.

Prognostic study, Level III. The aim of this study was to determine the incidence and demographics of idiopathic scoliosis (IS) in a large cohort of children in a Southern California integrated healthcare system, and to identify the demographic or clinical factors associated with the greatest risk of IS. Although many authors have reported on the incidence and prevalence of IS in children, there have been few incidence studies in the United States on large, self-contained populations. A retrospective chart analysis was done on diagnosed cases of IS within our integrated health care system in patients under age 18 years during the entire 2013 calendar year. Patient demographics were recorded and the incidence of IS was determined. Odds ratios (ORs) for having IS and for having more severe initial curve magnitudes based on demographics were determined using logistic regression models. IS Incidence was 3.9, 28.6, and 393 per 100,000, respectively, for the infantile, juvenile, and adolescent group. The female incidence was more than twice that of males in all age groups. Multivariate logistic regression analysis showed Asians and non-Hispanic Whites had the highest OR of IS (OR 1.54 and 1.32 with 95% confidence interval [CI] 1.33-1.79 and 1.19-1.47). Whites, Blacks, and mixed-race patients had a significantly higher initial curve magnitude than Hispanics; females also had a significantly greater initial curve magnitude than boys (18.1° vs. 16.7°). Underweight patients had a 50% increased OR of IS versus normal weight (95% CI 1.16-1.94) with a progressively decreased OR of IS as weight increased. Our study of a large integrated healthcare system sheds light on the incidence of IS and the ORs based on weight, sex, and ethnicity/race. The overall incidence was lower overall than previously thought.Level of Evidence: 3.

Clinical and Financial Implications of Second-Opinion Surgical Pathology Review.

Second-opinion pathology review identifies clinically significant diagnostic discrepancies for some patients. Discrepancy rates and laboratory-specific costs in a single health care system for patients referred from regional affiliates to a comprehensive cancer center ("main campus") have not been reported. Main campus second-opinion pathology cases for 740 patients from eight affiliated hospitals during 2016 to 2018 were reviewed. Chart review was performed to identify changes in care due to pathology review. To assess costs of pathology interpretation, reimbursement rates for consultation Current Procedural Terminology billing codes were compared with codes that would have been used had the cases originated at the main campus. Diagnostic discrepancies were identified in 104 (14.1%) patients, 30 (4.1%) of which resulted in a change in care. In aggregate, reimbursement for affiliate cases was 65.6% of the reimbursement for the same cases had they originated at the main campus. High-volume organ systems with low relative consultation reimbursement included gynecologic, breast, and thoracic. Preventable diagnostic errors are reduced by pathology review for patients referred within a single health care system. Although the resulting changes in care potentially lead to overall cost savings, the financial value of referral pathology review could be improved.

Use of primary care services among patients with chronic skin disease seen by dermatologists

BackgroundSkin diseases, such as psoriasis, hidradenitis suppurativa, acne, and alopecia areata, have increasingly been linked to systemic and mental health comorbidities, such as depression. Although identification and management of these comorbidities is typically a part of primary care, some patients might not have an established relationship with a primary care provider and may only be seeing their dermatologist.ObjectiveTo examine the frequency with which dermatologists are the main contact within a health care system for patients with these chronic skin conditions.MethodsWe performed a retrospective cohort study using Optum's deidentified Clinformatics Data Mart Database. The primary outcome was the proportion of patients who established care with a dermatologist and had no encounters with a primary care provider during the subsequent year after this dermatology encounter.ResultsAcross each of the skin diseases evaluated, 21.6%-31.2% of men and 16.9%-26.2% of women had no primary care visits in the subsequent year after establishing care with their dermatologist.Conclusion and RelevanceFor many patients with chronic skin diseases, their dermatologist might be their only source of contact with the health care system. There may be an opportunity for dermatologists to improve the quality of care for our patients by screening for associated comorbidities.

A Retrospective Review of the Appropriateness of D-Dimer Ordering and Interpretation Using Wells' Clinical Probability Criteria

Introduction The D-dimer has been validated in diagnostic venous thromboembolism (VTE) algorithms. The high sensitivity of the assay allows for safe exclusion of VTE in patients with low clinical pre-test probability and a negative D-dimer. The Wells score for Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) are validated pre-test probability tools which help guide physicians on when to order a D-dimer in patients with suspected VTE. However, we suspect these scoring tools are often under-utilized by physicians leading to inappropriate D-dimer ordering and subsequent interventions. We sought to explore the landscape of D-dimer ordering at our institution. Methods We conducted a retrospective chart review of 482 patients in whom a D-dimer had been ordered over a 3-month period at the University of Alberta Hospital, a tertiary care teaching hospital in Edmonton, Canada. Charts were reviewed for patient demographics, specialty of ordering physician, apparent indication for ordering, patient risk factors for VTE and evidence of a pre-test probability (PTP) calculation. WIf no PTP score was documented, we retrospectively calculated Wells DVT or PE scores. VTE was deemed likely with a calculated Wells score for DVT ≧2 or Wells score for PE >4. In the case of high PTP for PE, patients should go directly to imaging and a D-dimer should not be performed. A cut off of ≥ 0.50 mg/L was deemed a positive D-dimer (STA-LIATEST). We also reviewed subsequent investigations thought to be influenced by interpretation of the D-dimer including: ventilation/perfusion (V/Q) and pulmonary angiography (CTPA) scans, and upper and lower extremity doppler ultrasound studies. We then used multivariable logistic regression analysis to evaluate the proportion of patients who received imaging despite a low PTP and negative D-dimer. Results Seventy eight percent of D-dimers were ordered by Emergency physicians while 15.3% were drawn on admitted patients, and 5.8% in the outpatient setting. The indication for ordering was unknown in 87 (17.5%) of cases. Pre-test probability scores were documented in only 8 (1.6%) of cases. All of those documented were the Wells PE score. When Wells DVT and PE scores were calculated retrospectively, 30.0% and 17.1% (87 cases) were deemed 'likely' for VTE, respectively. However, imaging was performed in 172 cases (34.6%), including in 36 cases despite a negative D-dimer result and low PTP. In contrast, 68 cases (17.2%) had a D-dimer performed with a high Wells PTP for PE despite the recommendation to proceed directly to imaging. VTE (either DVT or PE) was confirmed by imaging in 32 (18.6%) of cases, the majority (53.1%) had a high retrospective PTP. Conclusions Inappropriate ordering and interpretation of D-dimers remains a significant problem despite the implementation of clinical guidelines and pre-test probability algorithms, namely the Wells score for DVT and PE meant to guide physicians. This leads to unnecessary cost, radiation exposure, and prolonged contact with the health care system for patients. This suggests the need for quality improvement initiatives which draw physician's attention to pre-test probability tools which can curbing subsequent inappropriate investigations and improve patient care.

Time Between an Emergency Department Visit and Initiation of Physical Therapist Intervention: Health Care Utilization and Costs.

The aim of this study was to examine the association between the length of time between an emergency department (ED) visit and the subsequent initiation of physical therapist intervention for low back pain (LBP) on 1-year LBP-related health care utilization (ie, surgery, advanced imaging, injections, long-term opioid use, ED visits) and costs. This retrospective cohort study focused on individuals who consulted the ED for an initial visit for LBP. Claims from a single statewide, all-payers database were used. LBP-related health care use and costs for the 12months after the ED visit were extracted. Poisson and general linear models weighted with inverse probability treatment weights were used to compare the outcomes of patients who attended physical therapy early or delayed after the ED visit. Compared with the delayed physical therapy group (n=94), the early physical therapy group (n=171) had a lower risk of receiving lumbar surgery (relative risk [RR]=0.47, 95% CI=0.26-0.86) and advanced imaging (RR=0.72, 95% CI=0.55-0.95), and they were less likely to have long-term opioid use (RR=0.45, 95% CI=0.28-0.76). The early physical therapy group incurred lower costs (mean=$3,806, 95% CI=$1,998-$4,184) than those in the delayed physical therapy group (mean=$8,689, 95% CI=$4,653-$12,727). Early physical therapy following an ED visit was associated with a reduced risk of using some types of health care and reduced health care costs in the 12months following the ED visit. The ED is an entry point into the health care system for patients with LBP. Until now, the impact of the length of time between an ED visit and physical therapy for LBP has not been well understood. This study shows that swift initiation of physical therapy following an ED visit for LBP is associated with lower LBP-related health utilization for some important outcomes and lower LBP-related health care costs.

Identifying Palliative Patients in General Practice: Focusing on the Place of Death and the Vital Role of Specialized Home Palliative Care: An Observational Study.

Objectives: Specialist palliative care was introduced into the German health care system for patients at the end of life. The primary objective of this study was to assess whether the provision of specialist home palliative care (SHPC) for outpatients increased the likelihood of patients dying at home. Methods: We studied data collected in 2015 from a German statutory health insurance company covering 3.872 million people. We evaluated how many patients were identified as needing palliative care and whether these patients were able to stay at home until death. The data were ascertained from general practices in Baden-Wuerttemberg, a part of Germany. Palliative care patients were identified using the International Classification of Diseases (ICD)-10 code Z51.5 or the assigned medical billing code of the German fee schedule. Patients receiving care from an SHPC team were identified using the billing codes 01425 or 01426. Adjusted odds ratios were calculated for the place of death with multivariable logistic regression. Results: We found 21,190 (0.55%) palliative patients in the whole population. Of these, 19,507 (92.05%) patients received general palliative care and 1683 (7.95%) patients received specialist palliative care. Mortality rate across all patients was 1.08% (41,800) and mortality rate of palliative patients was 44.08% (9494). In total, 19,833 (47.5%) of the general population died in hospitals, as opposed to only 2208 (23.2%) among palliative patients. Further analysis revealed that of those palliative patients receiving SHPC, 160 (13.3%) died in hospitals as opposed to 2048 (24.7%) of those receiving general care. The probability of dying at home increases already with the label "palliative patient" and gets stronger if care is provided by a specialist palliative care team. Conclusion: Most palliative patients are able to die at home. Palliative care teams are responsible for a small part of these patients. Despite the high symptom burden in this group, most are able to die at home.

Epidemiologic Survey of Legionella Urine Antigen Testing Within a Large Wisconsin-Based Health Care System.

Legionella pneumophila pneumonia is a life-threatening, environmentally acquired infection identifiable via Legionella urine antigen tests (LUAT). We aimed to identify cumulative incidence, demographic distribution, and undetected disease outbreaks of Legionella pneumonia via positive LUAT in a single eastern Wisconsin health system, with a focus on urban Milwaukee County. A multilevel descriptive ecologic study was conducted utilizing electronic medical record data from a large integrated health care system of patients who underwent LUAT from 2013 to 2017. A random sample inclusive of all positive tests was reviewed to investigate geodemographic differences among patients testing positive versus negative. Statistical comparisons used chi-squared or 2-sample t-tests; stepwise regression followed by binary logistic regression was used for multivariable analysis. Positive cases identified by LUAT were mapped to locate hotspots; positive cases versus total tests performed also were mapped by zip code. Of all LUAT performed (n=21,599), 0.68% were positive. Among those in the random sample (n=11,652), positive cases by LUAT were more prevalent in the June-November time period (86.2%) and younger patients (59.4 vs 67.7 years) and were disproportionately male (70.3% vs 29.7%) (P<0.0001 for each). Cumulative incidence was higher among nonwhite race/ethnicity (1.91% vs 1.01%, P<0.0001) but did not remain significant on multivariable analysis. Overall, 5507 tests were performed in Milwaukee County zip codes, yielding 82 positive cases by LUAT (60.7% of all positive cases in the random sample). A potential small 2016 outbreak was identified. Cumulative incidence of a positive LUAT was less than 1%. LUAT testing, if done in real time by cooperative health systems, may complement public health detection of Legionella pneumonia outbreaks.

Elderly People With Drug-Related Problems Identified in the Emergency Department: Impact of Therapeutic Complexity on Consultations to the Health System

Different scales have been validated to assess the medication regimen complexity. However, the effect of this complexity on the risk of health care center consultations in patients with drug-related problems is unknown. This study’s objective is to evaluate the association between the Medication Regimen Complexity Index (MCRI) and the number of drugs prescribed and new consultations to the health care system in patients who visit an emergency service due to drug-related problems. This is a retrospective observational study. We included patients &gt;65 years who attended in an emergency service for drug-related problems. To identify variables associated with health care center reconsultation, a multivariate analysis was performed, including demographic and comorbidity variables, number of drugs prescribed, and MCRI value. Two hundred and one patients were included. A significant association was found between the prescription of more than five drugs (odds ratio [OR] = 2.50, 95% confidence interval [CI] = [1.08, 5.79]), an MCRI &gt; 20 (2.98 [1.46–6.09]), and an increase in the number of drugs prescribed (2.87 [1.57–5.21]) and its MCRI (2.06 [1.13–3.77]) at discharge and a new visit to the emergency department. An association was found between the prescription of more than five drugs, an MCRI &gt; 20, an increase in the number of drugs, and in MCRI value at discharge and a new visit to any other health care center. The number of prescribed drugs and the medication complexity of patients who visit the emergency department for drug-related problems was associated with an increase in the number of revisits to the emergency department and to other health care centers.

Primary Care and Emergency Department Management of the Patient With Duchenne Muscular Dystrophy

Primary care providers (PCPs) are usually the first point of contact with the health care system for patients with Duchenne muscular dystrophy (DMD), and patients often present to emergency departments in which providers have little experience in dealing with this condition. With this article, we give primary care and emergency medicine providers a background in the common issues that affect people with DMD. By acquiring some specialized knowledge about the multisystem medical complications of DMD and by applying general principles of primary care, such as timely immunization, anticipatory safety counseling, behavioral screening, and routine nutritional and developmental assessments, the PCP can be a valued and effective medical provider to patients with DMD. The PCP can provide access to and effective coordination among the patient's specialty caregivers. Moreover, the PCP can become a trusted advisor to the patient and his family about important medical decisions, as well as issues in the psychosocial, behavioral, and educational domains. This article also contains a "pocket guide" used to assess and manage common urgent medical problems that cause patients with DMD to seek care in the emergency department. With the background information discussed in this article, both PCPs and emergency medicine physicians can skillfully care for patients with DMD in their respective settings, optimizing patient outcomes.

ACUTE ARTICULAR SYNDROME. THE CONCEPT OF EMERGENCY CARE IN RHEUMATOLOGY

The absence of a current emergency care system for rheumatic patients makes the solution of this problem relevant. Objective: to create and test a health care system for patients with acute articular syndrome (AAS) and to analyze the distribution of patients according to the profile of hospitalization. Subjects and methods. The practice of providing medical care to patients with AAS was studied using the materials of the I.I. Dzhanelidze Research Institute of Emergency Care (RI of EC) in 2008 to 2015. The causes of hospital admissions were analyzed by taking into account the verified nosological diagnosis. Results and discussion. The incidence of AAS in the general flow of patients referred for hospitalization was analyzed; the most frequent causes of AAS were determined. Trends in the referral of rheumatic patients to inpatient and outpatient treatment were analyzed separately. The decrease in the proportion of rheumatic patients in need of inpatient treatment from 76.7 to 50.8% during the study allows optimization of the costs of the health care system. Conclusion. The presented concept of providing medical care to patients with AAS has proven its effectiveness as a result of its testing at the RI of EC from 2008 to the present time. This concept can be recommended for its introduction in other subjects of the Russian Federation.

P149: Do patients presenting to the emergency department with a mental health crisis have access to community healthcare resources?

Introduction: The emergency department (ED) is often the first point of access to the health care system for patients with an acute mental health crisis. Outpatient resources are limited, typically do not operate after hours, and patients and their families often lack sufficient information on where and how to access mental health services within their communities. The objective of this study was to determine which community healthcare resources patients attempted to access for their mental health condition prior to presenting to the ED. Methods: Between April 2016 to June 2017, a convenience sample of adult ( 18 years) patients presenting to an academic ED (annual census 65,000) with a mental health complaint were invited to complete a 23-item, paper-based survey. The questionnaire was pilot-tested and peer-reviewed for feasibility and comprehension. Results: Of the 200 patients who completed the survey, mean (SD) age was 37 (16) years and 96 (48%) were male. 20 (10%) patients were brought to the ED involuntarily by police services. 175 (88%) had been previously diagnosed with a mental health condition, the most common being depression and/or anxiety (n=134, 67%). 47 (24%) patients indicated they were currently only connected to a primary care provider, while 94 (47%) patients indicated they had existing relationships with multiple mental healthcare providers. 117 (59%) patients attempted to see an alternative healthcare provider prior to coming to the ED. 78 (39%) patients had a pending scheduled appointment with a healthcare provider for their mental health condition, 44 (56%) of which were within 7 days of their ED visit, but chose to seek care in the ED. 38 (19%) patients either had a referral with no appointment date set, or had an impending mental health appointment scheduled more than 30 days from their ED visit. Conclusion: These findings suggest that most patients seeking ED care during a mental health crisis do so despite being connected to alternative healthcare providers and outpatient services. Future studies should attempt to determine reasons why patients with mental health conditions seek care in the ED, and examine barriers to mental health care in the community and outpatient setting.

GP Practices as a One-Stop Shop: How Do Patients Perceive the Quality of Care? A Cross-Sectional Study in Thirty-Four Countries.

To contribute to the current knowledge on how a broad range of services offered by general practitioners (GPs) may contribute to the patient perceived quality and, hence, the potential benefits of primary care. Between 2011 and 2013, primary care data were collected among GPs and their patients in 31 European countries, plus Australia, Canada, and New Zealand. In these countries, GPs are the main providers of primary care, mostly specialized in family medicine and working in the ambulatory setting. In this cross-sectional study, questionnaires were completed by 7,183 GPs and 61,931 visiting patients. Moreover, 7,270 patients answered questions about what they find important (their values). In the analyses of patient experiences, we adjusted for patients' values in each country to measure patient perceived quality. Perceived quality was measured regarding five areas: accessibility and continuity of care, doctor-patient communication, patient involvement in decision making, and comprehensiveness of care. The range of GP services was measured in relation to four areas: (1) to what extent they are the first contact to the health care system for patients in need of care, (2) their involvement in treatment and follow-up of acute and chronic conditions, in other words treatment of diseases, (3) their involvement in minor technical procedures, and (4) their involvement in preventive treatments. Data of the patients were linked to the data of the GPs. Multilevel modeling was used to construct scale scores for the experiences of patients in the five areas of quality and the range of services of GPs. In these four-level models, items were nested within patients, nested in GP practices, nested in countries. The relationship between the range of services and the experiences of patients was analyzed in three-level multilevel models, also taking into account the values of patients. In countries where GPs offer a broader range of services patients perceive better accessibility, continuity, and comprehensiveness of care, and more involvement in decision making. No associations were found between the range of services and the patient perceived communication with their GP. The range of GP services mostly explained the variation between countries in the areas of patient perceived accessibility and continuity of care. This study showed that in countries where GP practices serve as a "one-stop shop," patients perceive better quality of care, especially in the areas of accessibility and continuity of care. Therefore, primary care in a country is expected to benefit from investments in a broader range of services of GPs or other primary care physicians.

Quality improvement primer part 2: executing a quality improvement project in the emergency department.

The topics of quality improvement (QI) and patient safety have become important themes in health care in recent years, particularly in the emergency department setting, which is a frequent point of contact with the health care system for patients. In the first of three articles in this series meant as a QI primer for emergency medicine clinicians, we introduced the strategic planning required to develop an effective QI project using a fictional case study as an example. In this second article we continue with our example of improving time to antibiotics for patients with sepsis, and introduce the Model for Improvement. We will review what makes a good aim statement, the various categories of measures that can be tracked during a QI project, and the relative merits and challenges of potential change concepts and ideas. We will also present the Model for Improvement's rapid-cycle change methodology, the Plan-Do-Study-Act (PDSA) cycle. The final article in this series will focus on the evaluation and sustainability of QI projects.

Outcomes for bipolar patients assessed in the French expert center network: A 2-year follow-up observational study (FondaMental Advanced Centers of Expertise for Bipolar Disorder [FACE-BD]).

A new health care system for patients with bipolar disorders was established in France under the auspices of Fondation FondaMental, based on thorough clinical assessment of patients and on close collaborations between expert centers and referring practitioners. We report the results of outcomes after 2years of observational follow-up of adult patients assessed within the network. A total of 984 patients were included in the study. We compared several parameters (e.g., mood episodes and hospitalization) 1year before inclusion and after 2 years of observational follow-up using the patient as his or her own control. Other outcomes were compared at baseline and during follow-up. We estimated the evolution of these parameters over a period of 2years using mixed models for continuous parameters and a generalized estimating equation (GEE) model for categorical variables, adjusting for potential confounding factors. Mean age was 42.7(±12.5) years and 58.8% were women. The number of hospitalization days decreased by 55% when comparing 1year before inclusion vs the follow-up period. In addition, patients showed a clear functional improvement associated with a reduction of residual mood symptoms, diminished psychiatric comorbidities, improvement of sleep and a better adherence to treatment. This study demonstrates an overall improvement of patients followed for 2years after an assessment in expert centers for bipolar disorders. This new organization based on a thorough clinical assessment and on personalized recommendations (drug treatments, psycho-social strategies and lifestyle measures) sent to health care professionals, and actively involving patients and families, improves the prognosis of BD patients.

RETRACTED ARTICLE: Development of a medical big-data mining process using topic modeling

With the development of convergence information technology, all of the spaces and objects of human living have become digitized. In the health- and medical-service areas, IT supports Internet of things (IoT)-based medical services and health-care systems for patients. Medical facilities have been advanced on the basis of such IoT devices, and the digitized information on human behaviors and health makes the delivery of efficient and convenient health care possible. Under the given circumstances, health and medical care have been researched. For some of this research, the patient-health data were collected using IoT-based medical devices, and they served as a tool for medical diagnosis and treatment. This study proposes the development of a medical big-data mining process for which topic modeling is employed. The proposed method uses the big data that are offered by the open system of the health- and medical-services big data from the Health Insurance Review and Assessment Service, and their application follows the guidelines of the knowledge discovery in big-data process for data mining and topic modeling. For the medical data regarding the topic modeling, the public structured health- and medical-services big data, Open API, and patient datasets were used. For the document classification in the semantic situation of a topic, the Bag of Words technique and the latent Dirichlet allocation method were applied to find the document association for the development of the medical big-data mining process. In addition, this study conducted a performance evaluation of the topic-modeling accuracy based on the medical big-data mining process and the topic-modeling efficiency, and the effectiveness of the proposed method was examined.

Hepatitis Action Plan and Changing Trend of Liver Disease in Japan: Viral Hepatitis and Nonalcoholic Fatty Liver Disease.

In Japan, the estimated number of chronic hepatitis B virus infections was 1.1 to 1.4 million, and that of chronic hepatitis C virus was 1.9 to 2.3 million in 2000. The mortality of hepatocellular carcinoma had been increasing and hit the peak at around 2002, which subsequently started to decrease. Japan has a national action plan for addressing viral hepatitis called Basic Act on Hepatitis Measures, established in 2009. In 2011, basic guidelines for promotion of control measures for hepatitis were issued, comprising nine principles in order to promote measures to prevent hepatitis B and C. According to these guidelines, national and local governments share screening costs for testing hepatitis B and C in residents who are over 40 years old. Thus, out-of-pocket expenses from examinees are nil or reduced to the minimum. In addition, for patients with chronic hepatitis B or C and on treatment, drug prices of nucleotide analogs, interferon (IFN) treatment, or IFN-free direct antiviral agents along with examination expenses should be covered by special programs for viral hepatitis. The national and local governments cover the amount in excess of 100 to 200 USD of the cost of treatment. The proportion of liver cancer with nonviral etiology has been increasing in Japan. For the screening and follow-up of patients with nonalcoholic fatty liver disease, we demonstrated that interleukin 34 is a feasible fibrosis marker. Several advantages have prevailed in the Japanese health care systems for patients with viral liver disease compared with those in countries in the Western Pacific region.

Trends in the Management of Patients With Kidney Failure in Alberta, Canada (2004-2013).

Background:Based on clinical practice guidelines, specific quality indicators are examined to assess the performance of a health care system for patients with end-stage renal disease (ESRD). We examined trends in the proportion of patients with ESRD referred late to nephrology, timing of dialysis initiation in those with chronic kidney disease, and proportion of patients with ESRD treated with pre-emptive kidney transplantation or peritoneal dialysis (PD).Design:This was a retrospective cohort study.Setting:The study was conducted in Alberta, Canada.Patients:Alberta residents aged 18 years or older with incident ESRD requiring renal replacement therapy between 2004 and 2013 were included.Measurements:Descriptive statistics, and log binomial and linear regression models were used for analysis.Methods:We determined the proportion of patients with ESRD who did not see a nephrologist within 90 days prior to starting dialysis (late referrals) and those who were receiving PD 90 days after dialysis initiation. Among those who had been seen by a nephrologist for at least 90 days, we also assessed the proportion who initiated dialysis with estimated glomerular filtration rate (eGFR) higher than or equal to 10.5 mL/min/1.73 m2, and underwent a pre-emptive transplant.Results:Our cohort included 5343 patients (mean age 61.8 years, 61.2% male). Over a 10-year period, there was a decrease in the proportion of late referrals (26.4% to 21.1%, P = .001). We also noted a decrease in the proportion of dialysis initiation with eGFR higher than or equal to 10.5 mL/min/1.73 m2 (21.2% to 14.7%, P < .001), with a significant increase in the proportion of patients initiating dialysis as an inpatient (38.8% to 45.2%, P = .001). There was a non-significant decrease in both the proportion of patients treated with a pre-emptive transplant and PD at 90 days over the 10-year period.Limitations:The use of administrative data restricted the availability of clinical data regarding underlying circumstances of each quality indicator, including patient symptoms, indications for dialysis initiation, and PD eligibility.Conclusions:We noted improvement in late referrals and early dialysis initiation over time. However, we also noted low and stable use of pre-emptive kidney transplantation and PD at 90 days, which warrants further exploration. These findings support the need for quality improvement initiatives designed to address these gaps in care and improve outcomes for patients with kidney failure.
