Comparison of adverse maternal and perinatal outcomes between induction and expectant management among women with gestational diabetes mellitus at term pregnancy: a systematic review and meta-analysis.

BACKGROUND: Induction at 38-40 weeks of gestation has been broadly suggested for women with gestational diabetes mellitus (GDM), yet its benefits and risks remain unclear. This study aimed to systematically review and meta-analyze existing evidence on the effect of induction at term gestation among women with GDM. METHODS: We searched MEDLINE, EMBASE, Cochrane Libraries, and Web of Science from inception to June 2021. We included randomized controlled trials (RCTs) and observational studies comparing induction with expectant management among GDM term pregnancies. Primary outcomes included caesarean section (CS) and macrosomia. All screening and extraction were conducted independently and in duplicates. Meta-analyses with random-effects models were conducted to generate the pooled odds ratios (ORs) and 95% confidence intervals (CIs) using the Mantel-Haenszel method. Methodological quality was assessed independently by two reviewers using the Cochrane Risk of Bias Tool for RCTs and the Newcastle-Ottawa Scale for observational studies. RESULTS: Of the 4,791 citations, 11 studies were included (3 RCTs and 8 observational studies). Compared to expectant management, GDM women with induction had a significantly lower odds for macrosomia (RCTs 0.49 [0.30-0.81]); observational studies 0.64 [0.54-0.77]), but not for CS (RCTs 0.95 [0.64-1.43]); observational studies 1.03 [0.79-1.34]). Induction was associated with a lower odds of severe perineal lacerations in observational studies (0.59 [0.39-0.88]). No significant difference was observed for other maternal or neonatal morbidities, or perinatal mortality between groups. CONCLUSIONS: For GDM women, induction may reduce the risk of macrosomia and severe perineal lacerations compared to expectant management. Further rigorous studies with large sample sizes are warranted to better inform clinical implications.

Comparison of adverse perinatal outcomes between Asians and Caucasians: a population-based retrospective cohort study in Ontario.

BACKGROUND: Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. METHODS: We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. RESULTS: Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. CONCLUSION: There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

Higher success rates and satisfaction in difficult venous access patients with a guide wire-associated peripheral venous catheter.

STUDY OBJECTIVE: This study compares first pass success rates and patient and physician satisfaction scores of using a guide wire-associated peripheral venous catheter (GAPIV) vs a traditional peripheral venous catheter in difficult to obtain venous access patients. METHODS: A total of 200 patients were enrolled prospectively from a convenience sample in a large urban academic emergency department. Patients were included when they were deemed difficult access per study criteria. Patients were alternated to receiving either a traditional peripheral venous catheter or a GAPIV. The number of attempts, the number of catheters used, and patient and physician satisfaction scores were recorded. RESULTS: A total of 100 patients were enrolled into each group. First attempt success was 85% with GAPIV vs 22% with the traditional peripheral venous catheter (P < .0001). Sixty-two percent of patients required a second stick with the conventional catheter compared to 15% with the GAPIV. The average number of attempts overall for the GAPIV product was 1.2 with an SD of 0.4 attempts vs 1.9 and an SD of 0.6 attempts with the traditional peripheral venous catheter; P < .0001. Using a 5-point Likert scale, the GAPIV had a median patient satisfaction score of 5 at insertion compared with the traditional peripheral venous catheter score of 2; P < .0001. Median physician satisfaction with the GAPIV study device was 5 at time of insertion, compared to 3 for the traditional peripheral venous catheter. CONCLUSION: The GAPIV product demonstrated significantly higher first attempt success and patient satisfaction compared to a traditional peripheral venous catheter in difficult to obtain venous access patients. Physician satisfaction was also favorable due to ease of access, time, and efficiencies gained.

A microfluidic based in vitro model of synaptic competition.

Synaptic competition is widely believed to be central to the formation and function of neuronal networks, yet the underlying mechanisms are poorly described. To investigate synaptic competition in vitro, we have developed a novel two input pathway competition model using a 3-compartment microfluidic device. Axons from cultured rat cortical neurons from two different lateral compartments (inputs) innervate a common neuronal population in a separate central compartment. Inhibiting one input's activity, using the GABAAR agonist muscimol, resulted in increased synapse numbers and axon elongation of the opposing untreated (uninhibited) inputs in the central compartment. Time lapse imaging revealed that uninhibited inputs outgrew and outconnected their inhibited counterparts. This form of competition occurs during a sensitive period ending prior to 21 DIV and is NMDAR and CamKII dependent. Surprisingly, this form of plasticity was dependent on the age of the center compartment neurons but not of the competing inputs.

Long-acting injectables and risk for rehospitalization among patients with schizophrenia in the home care program in Taiwan.

We aimed at evaluating the relationship between medication and treatment effectiveness in a home care setting among patients with schizophrenia. Patients with schizophrenia hospitalized between 2004 and 2009 with a primary International Classification of Diseases, Ninth Revision, Clinical Modification code of 295 were identified from Psychiatric Inpatient Medical Claims Data released by the National Health Research Institute in Taiwan. Patients who joined the home care program after discharge and were prescribed long-acting injection (LAI) (the LAI group) or oral antipsychotic medications (the oral group) were included as study subjects. The final sample for the study included 810 participants in the LAI group and 945 in the oral group. Logistic regression was performed to examine the independent effect of LAI medication on the risk for rehospitalization within the 12-month observation window after controlling for patient and hospital characteristics and propensity score quintile adjustment. The unadjusted odds ratio for rehospitalization risk was 0.80 (confidence interval, 0.65-0.98) for the LAI group compared to the oral group. The adjusted odds ratio was further reduced to 0.78 (confidence interval, 0.63-0.97). Results remained unchanged when the propensity score quintiles were entered into the regression for further adjustment. In a home care setting, patients treated with long-acting antipsychotic agents are at a significantly lower risk for psychiatric rehospitalization than those treated with oral medication. Consequently, LAI home-based treatment for the prevention of schizophrenia relapse may lead to substantial clinical and economic benefits.

Why Female Smokers Have Poorer Long-Term Health Outcomes than Male Smokers: The Role of Cigarette Smoking During Pregnancy.

Objectives: Women's health status is better than men but the opposite is true for female smokers who usually have poorer long-health outcomes than male smokers. The objectives of this study were to thoroughly reviewed and analyzed relevant literature and to propose a hypothesis that may explain this paradox phenomenon. Methods: We conducted a search of literature from three English databases (EMBASE, MEDLINE, and Google Scholar) from inception to 13 November 2023. A combination of key words and/or subject headings in English was applied, including relevant terms for cigarette smoking, sex/gender, pregnancy, and health indicators. We then performed analysis of the searched literature. Results: Based on this review/analysis of literature, we proposed a hypothesis that may explain this paradox phenomenon: female smokers have worse long-term health outcomes than male smokers because some of them smoke during pregnancy, and the adverse effects of cigarette smoking during pregnancy is much stronger than cigarette smoking during non-pregnancy periods. Conclusion: Approval of our pregnancy-amplification theory could provide additional evidence on the adverse effect on women's long-term health outcomes for cigarette smoking during pregnancy.

Thyroid allostasis in drug-free affective disorder patients.

AIM: To assess the thyroid allostasis in drug-free patients with affective disorder. METHODS: Patients with major depressive disorder or bipolar disorder as drug-free, defined as those without psychiatric drugs exposure for at least 4 months before admission, from a tertiary hospital were recruited in this cross-sectional study. The primary outcomes were "structure parameters of thyroid homeostasis", which include "thyroid's secretory capacity" (SPINA-GT), "sum step-up activity of deiodinases" (SPINA-GD), the ratio of total to free thyroxine and "thyroid homeostasis central set point" (TSH index and "thyroid feedback quantile-based index" [TFQI]), calculated by TSH and thyroid hormones measured at admission. A healthy population and non-affective psychiatric disorder (schizophrenia) from the same catchment area were recruited as two comparison groups. RESULTS: A total of 1263 cases of major depressive disorder, 1619 cases of bipolar disorder, 1186 cases of schizophrenia, and 162 healthy controls were included in the study. Compared to healthy control, GD and ratio of total to free thyroxine were lower in affective disorders. Bipolar with mania episode had higher GT than bipolar with depressive episode and major depressive disorder (median level at 3.70 vs. 3.04 and 3.03, respectively). Compared with healthy control, schizophrenia had higher TSH index and TFQI, but no increase in these parameters in major depressive disorder and bipolar disorder. CONCLUSION: Affective disorders have a unique profile of thyroid allostasis with impaired step-up deiodinase activity and reduced serum protein binding of thyroid hormones, but no change in thyroid homeostasis central set point. Mania episode may be associated with higher thyroid secretory capacity.

Severe Mpox Among People With Advanced Human Immunodeficiency Virus Receiving Prolonged Tecovirimat in New York City.

Severe mpox has been observed in people with advanced human immunodeficiency virus (HIV). We describe clinical outcomes of 13 patients with advanced HIV (CD4 <200 cells/µL), severe mpox, and multiorgan involvement. Despite extended tecovirimat courses and additional agents, including vaccinia immune globulin, cidofovir, and brincidofovir, this group experienced prolonged hospitalizations and high mortality.

Piezoelectric tuning fork probe for atomic force microscopy imaging and specific recognition force spectroscopy of an enzyme and its ligand.

Piezoelectric quartz tuning fork has drawn the attention of many researchers for the development of new atomic force microscopy (AFM) self-sensing probes. However, only few works have been done for soft biological materials imaging in air or aqueous conditions. The aim of this work was to demonstrate the efficiency of the AFM tuning fork probe to perform high-resolution imaging of proteins and to study the specific interaction between a ligand and its receptor in aqueous media. Thus, a new kind of self-sensing AFM sensor was introduced to realize imaging and biochemical specific recognition spectroscopy of glucose oxidase enzyme using a new chemical functionalization procedure of the metallic tips based on the electrochemical reduction of diazonium salt. This scanning probe as well as the functionalization strategy proved to be efficient respectively for the topography and force spectroscopy of soft biological materials in buffer conditions.

Maternal glucose levels and future risk of developing cardiovascular disease: a systematic review and meta-analysis protocol.

INTRODUCTION: Hyperglycaemia during pregnancy has been considered as one of the risk factors for cardiovascular diseases (CVDs) among women. Although the evidence regarding the association between gestational diabetes mellitus (GDM) and subsequent CVD has been synthesised, there are no systematic reviews covering the evidence of the association among the non-GDM population. This systematic review and meta-analysis, therefore, aim to fill the gap by summarising existing evidence on the association between maternal glucose levels and the risk of future CVD in pregnant women with or without a diagnosis of GDM. METHODS AND ANALYSIS: This systematic review protocol was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines. Comprehensive literature searches were performed in the following electronic databases: MEDLINE, EMBASE and CINAHL to identify relevant papers from inception to 31 December 2022. All observational studies (case-control studies, cohort studies and cross-sectional studies) will be included. Two reviewers will perform the abstract and full-text screening based on the eligibility criteria through Covidence. The Newcastle-Ottawa Scale will be used to assess the methodological quality of included studies. Statistical heterogeneity will be assessed by using the I2 test and Cochrane's Q test. If the included studies are found to be homogeneous, pooled estimates will be calculated and meta-analysis will be performed using Review Manager 5 (RevMan) software. Random effects will be used to determine weights for meta-analysis, if needed. Pre-specified subgroup analysis and sensitivity analysis will be performed, if needed. The study results will be presented in the sequence of main outcomes, secondary outcomes and important subgroup analysis for each type of glucose level separately. ETHICS AND DISSEMINATION: Given no original data will be collected, ethics approval is not applicable for this review. The results of this review will be disseminated by publication and conference presentation. PROSPERO REGISTRATION NUMBER: CRD42022363037.

Who's Accountable? Low-Value Care Received By Medicare Beneficiaries Outside Of Their Attributed Health Systems.

Policy makers and payers increasingly hold health systems accountable for spending and quality for their attributed beneficiaries. Low-value care-medical services that offer little or no benefit and have the potential for harm in specific clinical scenarios-received outside of these systems could threaten success on both fronts. Using national Medicare data for fee-for-service beneficiaries ages sixty-five and older and attributed to 595 US health systems, we describe where and from whom they received forty low-value services during 2017-18 and identify factors associated with out-of-system receipt. Forty-three percent of low-value services received by attributed beneficiaries originated from out-of-system clinicians: 38 percent from specialists, 4 percent from primary care physicians, and 1 percent from advanced practice clinicians. Recipients of low-value care were more likely to obtain that care out of system if age 75 or older (versus ages 65-74), male (versus female), non-Hispanic White (versus other races or ethnicities), rural dwelling (versus metropolitan dwelling), more medically complex, or experiencing lower continuity of care. However, out-of-system service receipt was not associated with recipients' health systems' accountable care organization status. Health systems might improve quality and reduce spending for their attributed beneficiaries by addressing out-of-system receipt of low-value care-for example, by improving continuity.

Racial differences in low value care among older adult Medicare patients in US health systems: retrospective cohort study.

OBJECTIVE: To characterize racial differences in receipt of low value care (services that provide little to no benefit yet have potential for harm) among older Medicare beneficiaries overall and within health systems in the United States. DESIGN: Retrospective cohort study SETTING: 100% Medicare fee-for-service administrative data (2016-18). PARTICIPANTS: Black and White Medicare patients aged 65 or older as of 2016 and attributed to 595 health systems in the United States. MAIN OUTCOME MEASURES: Receipt of 40 low value services among Black and White patients, with and without adjustment for patient age, sex, and previous healthcare use. Additional models included health system fixed effects to assess racial differences within health systems and separately, racial composition of the health system's population to assess the relative contributions of individual patient race and health system racial composition to low value care receipt. RESULTS: The cohort included 9 833 304 patients (6.8% Black; 57.9% female). Of 40 low value services examined, Black patients had higher adjusted receipt of nine services and lower receipt of 20 services than White patients. Specifically, Black patients were more likely to receive low value acute diagnostic tests, including imaging for uncomplicated headache (6.9% v 3.2%) and head computed tomography scans for dizziness (3.1% v 1.9%). White patients had higher rates of low value screening tests and treatments, including preoperative laboratory tests (10.3% v 6.5%), prostate specific antigen tests (31.0% v 25.7%), and antibiotics for upper respiratory infections (36.6% v 32.7%; all P<0.001). Secondary analyses showed that these differences persisted within given health systems and were not explained by Black and White patients receiving care from different systems. CONCLUSIONS: Black patients were more likely to receive low value acute diagnostic tests and White patients were more likely to receive low value screening tests and treatments. Differences were generally small and were largely due to differential care within health systems. These patterns suggest potential individual, interpersonal, and structural factors that researchers, policy makers, and health system leaders might investigate and address to improve care quality and equity.

Improving patient flow in acute coronary syndromes in the face of hospital crowding.

BACKGROUND: The current paradigm for the evaluation of patients with suspected acute coronary syndromes (ACS) in the emergency department (ED) is focused on the identification of patients with active underlying coronary disease. The majority of patients evaluated in the ED setting do not have active underlying cardiac disease. OBJECTIVE: To measure the effect of bedside point-of-care (POC) cardiac biomarker testing on telemetry unit admissions from the ED. Furthermore, to evaluate the effect telemetry admissions have on ED length of stay (LOS) and overall hospital LOS. METHODS: Primary data were collected over two 6-month periods in an urban teaching hospital ED. This was an observational cohort study conducted pre- and post-availability of a POC testing platform for cardiac biomarkers. Major measures included number of overall telemetry admissions, ED LOS, hospital LOS, and disposition. Patients were followed at 30 days for significant cardiac events, repeat ED visit or admission, and death. RESULTS: In the post-implementation period there was a 30% (95% confidence interval [CI] 36-44%) reduction in admissions to telemetry with a 33% (95% CI 26-39%) reduction in ED LOS and a 20% (95% CI 7-34%) reduction in hospital LOS. There was a 62% reduction in overall mortality between the pre-implementation period and the post-implementation period (p=0.001). CONCLUSION: The focused use of a rapid cardiac disposition protocol can dramatically impact resource utilization, expedite patient flow, and improve short-term outcomes for patients with suspected ACS.

Higher central set point of thyroid homeostasis in drug-naïve patients affected by first episode schizophrenia.

AIM: To assess central set point of thyroid homeostasis in drug-naïve patients affected by first episode schizophrenia. METHODS: This cross-sectional study was conducted in Xinxiang city, Henan, China. Patients were drug-naïve patients affected by first episode schizophrenia, aged 14-50 years old and admitted to the "Second Affiliated Hospital of Xinxiang Medical University" from January 2018 to December 2018. Controls were healthy individuals who underwent annual health from Xinxiang city, a community population of the same age and time period. The parameters of "central set point of thyroid homeostasis" were measured by "thyroid-stimulating hormone (TSH) index" and "thyroid feedback quantile-based index". The parameters were compared between schizophrenia patients and controls. Linear regression models adjusted by age and sex were used to assess the association of schizophrenia with the parameters. RESULTS: A total of 235 patients and 121 controls were included in this study. Patients affected by schizophrenia had significantly higher prevalence of hyperthyroxinemia and levels of free T4, "TSH index", and "thyroid feedback quantile-based index" than controls. After adjusting age and sex, schizophrenia was independently associated with the higher level of "TSH index" (adjusted ß 0.33, 95 % confidence interval 0.17, 0.49) and "thyroid feedback quantile-based index" (adjusted ß 0.21, 95 % confidence interval 0.12, 0.30). The results with age and sex matched patients and controls were similar to those observed in the overall study population. CONCLUSION: Higher central set point may be the underlying mechanism of thyroid allostatic load in drug-naïve patients affected first episode schizophrenia.

Identifying and addressing conflicting results across multiple discordant systematic reviews on the same question: protocol for a replication study of the Jadad algorithm.

INTRODUCTION: An increasing growth of systematic reviews (SRs) presents notable challenges for decision-makers seeking to answer clinical questions. In 1997, an algorithm was created by Jadad to assess discordance in results across SRs on the same question. Our study aims to (1) replicate assessments done in a sample of studies using the Jadad algorithm to determine if the same SR would have been chosen, (2) evaluate the Jadad algorithm in terms of utility, efficiency and comprehensiveness, and (3) describe how authors address discordance in results across multiple SRs. METHODS AND ANALYSIS: We will use a database of 1218 overviews (2000-2020) created from a bibliometric study as the basis of our search for studies assessing discordance (called discordant reviews). This bibliometric study searched MEDLINE (Ovid), Epistemonikos and Cochrane Database of Systematic Reviews for overviews. We will include any study using Jadad (1997) or another method to assess discordance. The first 30 studies screened at the full-text stage by two independent reviewers will be included. We will replicate the authors' Jadad assessments. We will compare our outcomes qualitatively and evaluate the differences between our Jadad assessment of discordance and the authors' assessment. ETHICS AND DISSEMINATION: No ethics approval was required as no human subjects were involved. In addition to publishing in an open-access journal, we will disseminate evidence summaries through formal and informal conferences, academic websites, and across social media platforms. This is the first study to comprehensively evaluate and replicate Jadad algorithm assessments of discordance across multiple SRs.

Estimating the clinical impact of bringing a multimarker cardiac panel to the bedside in the ED.

OBJECTIVES: We examined the use of point-of-care (POC) testing of cardiac biomarkers against standard core laboratory testing to determine the time-savings and estimate a cost-benefit ratio at our institution. METHODS: We prospectively enrolled 151 patients presenting to the emergency department undergoing evaluation for acute coronary syndrome and conducted both central laboratory troponin T (TnT) testing at baseline and 6 hours as well as POC assays of creatine kinase MB, troponin I (TnI), and myoglobin at baseline and 2 hours. Sensitivity/specificity was calculated to measure the ability of the POC-accelerated pathway to identify enzyme elevations at rates parallel to our core laboratory. The time-savings were calculated as the difference between the median of the current protocol and the accelerated POC pathway. RESULTS: Troponin T tests were elevated in 12 patients, which were all detected by the accelerated pathway yielding a relative sensitivity of 100%. Time-saving between the accelerated pathway and core laboratory showed a saving of 390 minutes (6.5 hours). The accelerated POC pathway would have benefited 60% (95% confidence interval [CI], 52%-68%) of our patients with an estimated cost of $7.40 (95% CI, $6.40-$8.70) per direct patient care hour saved. CONCLUSION: Our data suggest that the use of an accelerated cardiac POC pathway could have dramatically impacted the care provided to a large percentage of our patients at a minimal cost per direct patient care hour saved.

Costs and Consequences of Eliminating a Routine, Point-Of-Care HIV Screening Program in a High-Prevalence Jail.

INTRODUCTION: This study aims to assess the public health impact of eliminating a longstanding routine HIV screening program and replacing it with targeted testing. In addition, costs, outcomes, and cost effectiveness of routine screening are compared with those of targeted testing in the Fulton County Jail, Atlanta, Georgia. METHODS: A published mathematical model was used to assess the cost effectiveness and public health impact of routine screening (March 2013-February 2014) compared with those of targeted testing (January 2018-December 2018) from a health system perspective. Costs, outcomes, and other model inputs were derived from the testing programs and the published literature, and the cost effectiveness analysis was conducted from 2019 to 2020. RESULTS: Routine screening identified 74 more new HIV infections over 1 year than targeted testing, resulting in an estimated 10 HIV transmissions averted and 45 quality-adjusted life-years saved, and was cost saving. The missed opportunity to diagnose infections because routine screening was eliminated resulted in an estimated 8.4 additional HIV transmissions and $3.7 million in additional costs to the healthcare system. CONCLUSIONS: Routine HIV screening in high-prevalence jails is cost effective and has a larger impact on public health than targeted testing. Prioritizing sustained funding for routine, jail-based HIV screening programs in high-prevalence areas may be important to realizing the national HIV prevention goals.

Low-Value Care at the Actionable Level of Individual Health Systems.

Importance: Low-value health care remains prevalent in the US despite decades of work to measure and reduce such care. Efforts have been only modestly effective in part because the measurement of low-value care has largely been restricted to the national or regional level, limiting actionability. Objectives: To measure and report low-value care use across and within individual health systems and identify system characteristics associated with higher use using Medicare administrative data. Design, Setting, and Participants: This retrospective cohort study of health system-attributed Medicare beneficiaries was conducted among 556 health systems in the Agency for Healthcare Research and Quality Compendium of US Health Systems and included system-attributed beneficiaries who were older than 65 years, continuously enrolled in Medicare Parts A and B for at least 12 months in 2016 or 2017, and eligible for specific low-value services. Statistical analysis was conducted from January 26 to July 15, 2021. Main Outcomes and Measures: Use of 41 individual low-value services and a composite measure of the 28 most common services among system-attributed beneficiaries, standardized to distance from the mean value. Measures were based on the Milliman MedInsight Health Waste Calculator and published claims-based definitions. Results: Across 556 health systems serving a total of 11 637 763 beneficiaries, the mean (SD) use of each of the 41 low-value services ranged from 0% (0.01%) to 28% (4%) of eligible beneficiaries. The most common low-value services were preoperative laboratory testing (mean [SD] rate, 28% [4%] of eligible beneficiaries), prostate-specific antigen testing in men older than 70 years (mean [SD] rate, 27% [8%]), and use of antipsychotic medications in patients with dementia (mean [SD] rate, 24% [8%]). In multivariable analysis, the health system characteristics associated with higher use of low-value care were smaller proportion of primary care physicians (adjusted composite score, 0.15 [95% CI, 0.04-0.26] for systems with less than the median percentage of primary care physicians vs -0.16 [95% CI, -0.27 to -0.05] for those with more than the median percentage of primary care physicians; P < .001), no major teaching hospital (adjusted composite, 0.10 [95% CI, -0.01 to 0.20] without a teaching hospital vs -0.18 [95% CI, -0.34 to -0.02] with a teaching hospital; P = .01), larger proportion of non-White patients (adjusted composite, 0.15 [95% CI, -0.02 to 0.32] for systems with >20% of non-White beneficiaries vs -0.06 [95% CI, -0.16 to 0.03] for systems with ≤20% of non-White beneficiaries; P = .04), headquartered in the South or West (adjusted composite, 0.28 [95% CI, 0.14-0.43] for the South and 0.22 [95% CI, 0.02-0.42] for the West compared with -0.09 [95% CI, -0.26 to 0.08] for the Northeast and -0.44 [95% CI, -0.60 to -0.28] for the Midwest; P < .001), and serving areas with more health care spending (adjusted composite, 0.23 [95% CI, 0.11-0.35] for areas above the median level of spending vs -0.24 [95% CI, -0.36 to -0.12] for areas below the median level of spending; P < .001). Conclusions and Relevance: The findings of this large cohort study suggest that system-level measurement and reporting of specific low-value services is feasible, enables cross-system comparisons, and reveals a broad range of low-value care use.

A nationwide study of the risk of all-cause, sudden death, and cardiovascular mortality among antipsychotic-treated patients with schizophrenia in Taiwan.

INTRODUCTION: Studies have reported higher risks of mortality for patients with schizophrenia, compared to the general population. This study aimed to evaluate the risk of all-cause, sudden death, and cardiovascular mortality among patients with schizophrenia in terms of types of antipsychotics. METHODS: A retrospective cohort study assessed the risk of mortality among antipsychotic-treated patients with schizophrenia. The study linked the Taiwan National Health Insurance (NHI) claims and National Register of Death databases from 2001 to 2015. Patients were hierarchically assigned to the following index antipsychotic treatment groups: atypical long acting injection (LAI), typical LAI, atypical oral, and typical oral. RESULTS: A total of 68,159 antipsychotic-treated patients with schizophrenia were analyzed. Under the hierarchical grouping, the largest percentages of patients were on atypical oral antipsychotic regimens (65.51%), followed by typical oral (14.00%), typical LAI (12.84%), and atypical LAI (7.65%). Typical oral patients had the highest incidence of all-cause mortality of 27.48 per 1000 patient-years and the atypical LAI group had the lowest incidence (13.95 per 1000 patient-years). Compared to typical oral users, there were lower risks of all-cause mortality for users of atypical LAI (aHR = 0.62, 95% CI: 0.47-0.81), typical LAI (aHR = 0.65, 95% CI: 0.55-0.78), and atypical orals (aHR = 0.55, 95% CI: 0.49-0.62). CONCLUSION: Compared to typical oral users, we found a lower risk of all-cause mortality, sudden death, and cardiovascular mortality among schizophrenia users of LAIs and oral atypicals. Further research is warranted to characterize the risk of mortality among users of more recently available LAIs in the Asia Pacific region and elsewhere.

Sources of Low-Value Care Received by Medicare Beneficiaries and Associated Spending Within US Health Systems.

This cross-sectional study examines referrals for low-value health care services and associated spending by ordering clinician among Medicare beneficiaries.
