A framework for assessing outcomes from newborn screening: on the road to measuring its promiseNewborn screening (NBS) is intended to identify congenital conditions prior to the onset of symptoms in order to provide early intervention that leads to improved outcomes. NBS is a public health success, providing reduction in mortality and improved developmental outcomes for screened conditions. However, it is less clear to what extent newborn screening achieves the long-term goals relating to improved health, growth, development and function. We propose a framework for assessing outcomes for the health and well-being of children identified through NBS programs. The framework proposed here, and this manuscript, were approved for publication by the Secretary of Health and Human Services' Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC). This framework can be applied to each screened condition within the Recommended Uniform Screening Panel (RUSP), recognizing that the data elements and measures will vary by condition. As an example, we applied the framework to sickle cell disease and phenylketonuria (PKU), two diverse conditions with different outcome measures and potential sources of data. Widespread and consistent application of this framework across state NBS and child health systems is envisioned as useful to standardize approaches to assessment of outcomes and for continuous improvement of the NBS and child health systems. SIGNIFICANCE: Successful interventions for newborn screening conditions have been a driving force for public health newborn screening for over fifty years. Organizing interventions and outcome measures into a standard framework to systematically assess outcomes has not yet come into practice. This paper presents a customizable outcomes framework for organizing measures for newborn screening condition-specific health outcomes, and an approach to identifying sources and challenges to populating those measures.

A pilot study evaluating a simple cardiac dysfunction score to predict complications and survival among critically-ill patients with traumatic brain injuryPURPOSE: To describe the frequency of cardiovascular complications and cardiac dysfunction in critically-ill patients with moderate-severe traumatic brain injury (msTBI) and cardiac factors associated with in-hospital survival. METHODS: Retrospective analysis of a prospective cohort study at a single Level-1 trauma center with a dedicated neuro-trauma intensive care unit (ICU). Adult patients admitted to the ICU with msTBI were consecutively enrolled in the prospective OPTIMISM study between November 2009 and January 2017. Cardiac dysfunction was measured using a combination of EKG parameters, echocardiography abnormalities, and peak serum troponin-I levels during the index hospitalization. These items were combined into a cardiac dysfunction index (CDI), ranging from 0 to 3 points and modeled in a Cox regression analysis. RESULTS: A total of 326 patients with msTBI were included. For every one-point increase in the CDI, the multivariable adjusted risk of dying during the patient's acute hospitalization more than doubled (adjusted HR 2.41; 95% CI 1.29-4.53). CONCLUSION: Cardiac dysfunction was common in patients with msTBI and independently associated with more severe brain injury and a reduction in hospital survival in this population. Further research is needed to validate the CDI and create more precise scoring tools.

Atrial flutter: Clinical risk factors and adverse outcomes in the Framingham Heart StudyBACKGROUND: Few epidemiologic cohort studies have evaluated atrial flutter (flutter) as an arrhythmia distinct from atrial fibrillation (AF). OBJECTIVE: The purpose of this study was to examine the clinical correlates of flutter and its associated outcomes to distinguish them from those associated with AF in the Framingham Heart Study. METHODS: We reviewed and adjudicated electrocardiograms (ECGs) previously classified as flutter or AF/flutter and another 100 ECGs randomly selected from AF cases. We examined the clinical correlates of flutter by matching up to 5 AF and 5 referents to each flutter case using a nested case referent design. We determined the 10-year outcomes associated with flutter with Cox models. RESULTS: During mean follow-up of 33.0 +/- 12.2 years, 112 participants (mean age 72 +/- 10 years, 30% women) developed flutter. In multivariable analyses, smoking (odds ratio [OR] 2.84, 95% confidence interval [CI] 1.54-5.23), increased PR interval (OR 1.28 per SD, 95% CI 1.03-1.60), myocardial infarction (OR 2.25, 95% CI 1.05-4.80) and heart failure (OR 5.22, 95% CI 1.26-21.64) were associated with incident flutter. In age- and sex-adjusted models, flutter (vs referents) was associated with 10-year increased risk of AF (hazard ratio [HR] 5.01, 95% CI 3.14-7.99), myocardial infarction (HR 3.05, 95% CI 1.42-6.59), heart failure (HR 4.14, 95% CI 1.90-8.99), stroke (HR 2.17, 95% CI 1.13-4.17), and mortality (HR 2.00, 95% CI 1.44-2.79). CONCLUSION: We identified the clinical correlates associated with flutter and observed that flutter was associated with multiple adverse outcomes.

Factors Associated with Mortality After Undergoing Thrombectomy for Acute Ischemic StrokeBackground: Mechanical thrombectomy is the gold standard for treating patients with certain acute ischemic stroke (AIS) due to large vessel occlusion (LVO). However, even with major advancements and increasing procedural volumes, acute endovascular therapy remains a high-risk procedure with a considerable 90-day mortality rate, affected by a variety of factors. Purpose: To investigate various clinical and procedural factors associated with 90-day mortality in patients undergoing mechanical thrombectomy for emergent treatment of AIS and determine which of these factors made unique contributions to post-thrombectomy prognosis. Methods: We examined a prospective registry of 323 patients treated with endovascular thrombectomy for AIS between 2016 and 2019 at a high-volume comprehensive stroke center in central Massachusetts. We developed two multivariable logistic regression models adjusting for the contributions of baseline characteristics and recanalization parameters, to identify potential predictors of mortality at 90 days. Results: Among 323 AIS patients treated with mechanical thrombectomy, the overall rate of successful recanalization was 86% and the overall post-procedure mortality rate was 29% by 90 days. After univariate analysis, a baseline multivariable model comprised of: history of stroke (OR 0.28, 95% CI 0.09 – 0.68), pre-stroke modified Rankin Scale (mRS 2: OR 3.75, 95% CI), severe admission National Institutes of Health Stroke Scale (NIHSS 21–42: OR 12.36, 95% CI 1.48 – 103.27), internal carotid artery (ICA) occlusion (OR 2.77, 95% CI 1.18 – 6.55), and posterior circulation occlusion (OR 2.69, 95% CI 1.06 – 6.83) was prognostic of 90-day mortality. A second multivariable model also found the procedural factors of: clot obtained after each pass (OR 0.49, 95% CI 0.24 – 1.00), successful recanalization (OR 0.21, 95% CI 0.06 – 0.8) and symptomatic intracranial hemorrhage (sICH; OR 17.89, 95% CI 5.22 – 61.29) to be identifiable predictors of post-thrombectomy mortality. Conclusion: Death within 90 days after thrombectomy was increased among patients with higher pre-stroke disability, higher stroke severity on admission, ICA or posterior occlusion, and those with sICH complication. A history of stroke, clot extraction after each device pass, and successful recanalization are associated with decreased 90-day mortality. These identifiable contributors may inform patient selection, prognosis evolution, and shared decision-making regarding emergent thrombectomy for treatment of AIS.

Fracture liaison services improve outcomes of patients with osteoporosis-related fractures: A systematic literature review and meta-analysisOBJECTIVES: This systematic review and meta-analysis evaluated the outcomes of patients with osteoporosis-related fractures managed through fracture liaison services (FLS) programs. METHODS: Medline, PubMed, EMBASE, and the Cochrane Library were searched (January 2000-February 2017 inclusive) using the keywords 'osteoporosis', 'fractures', 'liaison', and 'service' to identify randomised controlled trials and observational studies of patients aged > /=50years with osteoporosis-related fractures in hospital, clinic, community, or home-based settings who were managed using FLS. Risk of bias was assessed at outcome level. Meta-analysis followed a random-effects and fixed-effects model. Outcomes of interest were incidence of bone mineral density (BMD) testing, treatment initiation, adherence, re-fractures, and mortality due to osteoporosis treatment. RESULTS: A total of 159 publications were identified for the systematic literature review; 74 controlled studies (16 RCTs; 58 observational studies) were included in the meta-analysis. Overall, 41 of 58 observational studies and 12 of 16 RCTs were considered of high quality. Compared with patients receiving usual care (or those in the control arm), patients receiving care from an FLS program had higher rates of BMD testing (48.0% vs 23.5%) and treatment initiation (38.0% vs 17.2%) and greater adherence (57.0% vs 34.1%). Unweighted average rates of re-fracture were 13.4% among patients in the control arm and 6.4% in the FLS arm. Unweighted average rates of mortality were 15.8% in the control arm and 10.4% in the FLS arm. Meta-analysis revealed significant FLS-associated improvements in all outcomes versus non-FLS controls, with BMD testing increased by 24 percentage points (95% confidence interval [CI] 0.18-0.29), 20 percentage points for treatment rates (95% CI 0.16-0.25), and 22 percentage points for adherence (95% CI 0.13-0.31) and absolute risk of re-fracture reduced by five percentage points (95% CI -0.08 to -0.03) and mortality reduced by three percentage points (95% CI -0.05 to -0.01). CONCLUSION: FLS programs improved outcomes of osteoporosis-related fractures, with significant increases in BMD testing, treatment initiation, and adherence to treatment and reductions in re-fracture incidence and mortality.

Impact of COVID-19 on clinical outcomes of robotic retromuscular ventral hernia repairBackground: The COVID-19 pandemic disrupted the healthcare sector and forced hospitals to limit the number of elective procedures with the goal of reducing overcrowding of wards and thus viral transmission. Recent trends for ventral hernia repair have shifted towards retromuscular techniques, which normally require a longer length of stay. Therefore, the aim of this study is to investigate the impact of the COVID-19 pandemic on clinical outcomes of robotic retromuscular ventral hernia repair (rRVHR). Methods: Patients who underwent rRVHR up to 600 days before and after March 10, 2020, were included in this retrospective study and assigned to the pre- or post-COVID group depending on the date of their procedure. Pre-, intra-, and postoperative variables including patients' demographics, hernia characteristics, complications, and hernia recurrence were compared between both groups. Results: 153 (46% female) and 141 (51% female) patients were assigned to the pre- and post-COVID groups respectively. Median age was statistically different between both groups [pre-COVID: 57 (48-68) vs. post-COVID 55 (42-64) years, p = 0.045]. Median hospital length of stay (LOS) was 0 day (0-1) in both groups, and same day discharge were 61% pre-pandemic and 70% post-pandemic (p = 0.09). Mean postoperative follow-up was 39.2 (4.1-93.6) months. In total, 26 pre-COVID patients had postoperative complications, out of which 7 were pulmonary complications, whereas 23 complications were recorded in the post-COVID group, with only 3 pulmonary complications (p = 0.88). Rate of surgical-site events was comparable between both groups, and no recurrences were recorded. Conclusion: This is the first study to describe the impact of the COVID-19 on rRVHR. Hospital LOS was comparable between both groups. Rates of medical and hernia specific complications were not altered by the pandemic.

Predictors of mortality in the elderly after open repair for perforated peptic ulcer diseaseBACKGROUND: As the U.S. population ages and the number of emergent surgical repairs for perforated peptic ulcer disease (PUD) rise, contemporary national data evaluating operative outcomes for open surgical repair for perforated PUD among the elderly are lacking. MATERIALS AND METHODS: The National Surgical Quality Improvement Program (2007-2014) was queried for patients > /=65 y who underwent open surgical repair for perforated PUD. The primary outcome was 30-d mortality. Secondary outcomes included 30-d postoperative complications. Univariate and multivariable regression analyses were performed. RESULTS: Overall, 2131 patients underwent open surgical repair for perforated PUD. Among those who died, more used steroids preoperatively (15% versus 9%, P = 0.001) and fewer were independent preoperatively (55% versus 83%, P < 0.0001) compared to those who were alive 30-d postoperatively. Common postoperative complications were septic shock (15%) and pneumonia (12%). The overall 30-d mortality rate was 17.7%, with more deaths in subsequent decades of life (65-75 y 13% versus 75-84 y 18% versus > 85 y 24%, P < 0.0001). After adjustment for other factors, mortality was significantly associated with older age (85+ versus 65-74 y) (odds ratio [OR], 1.5; 95% confidence interval [CI], 0.8, 1.7), dependent functional status preoperatively ([OR], 0.2; 95% CI, 0.2, 0.3), and American Society of Anesthesiologist classification > /=4 (OR, 3.2; 95% CI, 2.4, 4.3). CONCLUSIONS: At U.S. hospitals, open surgical repair, the accepted treatment of perforated PUD, among the elderly is associated with significant 30-d morbidity and mortality rates that are unacceptably high in our contemporary era. Furthermore, mortality rates are associated with older age. Therefore, as the elderly population continues to increase in the United States, preoperative, perioperative, and postoperative measures must be taken to reduce this high morbidity and mortality rates.

Recent Trends in Oral Anticoagulant Use and Post-Discharge Complications Among Atrial Fibrillation Patients with Acute Myocardial InfarctionBackground: Atrial fibrillation (AF) is a common complication of acute myocardial infarction (AMI).The CHA2DS2VAScand CHADS2risk scoresare used to identifypatients with AF at risk for strokeand to guide oral anticoagulants (OAC) use, including patients with AMI. However, the epidemiology of AF, further stratifiedaccording to patients' risk of stroke, has not been wellcharacterized among those hospitalized for AMI. Methods: We examined trends in the frequency of AF, rates of discharge OAC use, and post-discharge outcomes among 6,627 residents of the Worcester, Massachusetts area who survived hospitalization for AMI at 11 medical centers between 1997 and 2011. Results: A total of 1,050AMI patients had AF (16%) andthe majority (91%)had a CHA2DS2VAScscore > 2.AF rates were highest among patients in the highest stroke risk group.In comparison to patients without AF, patients with AMI and AF in the highest stroke risk category had higher rates of post-discharge complications, including higher 30-day re-hospitalization [27 % vs. 17 %], 30-day post-discharge death [10 % vs. 5%], and 1-year post-discharge death [46 % vs. 18 %] (p < 0.001 for all). Notably, fewer than half of guideline-eligible AF patients received an OAC prescription at discharge. Usage rates for other evidence-based therapies such as statins and beta-blockers,lagged in comparison to AMI patients free from AF. Conclusions: Our findings highlight the need to enhance efforts towards stroke prevention among AMI survivors with AF.

Recovery Colleges Characterisation and Testing in England (RECOLLECT): rationale and protocolBackground: Recovery Colleges are a relatively recent initiative within mental health services. The first opened in 2009 in London and since then numbers have grown. They are based on principles of personal recovery in mental health, co-production between people with lived experience of mental health problems and professionals, and adult learning. Student eligibility criteria vary, but all serve people who use mental health services, with empirical evidence of benefit. Previously we developed a Recovery College fidelity measure and a preliminary change model identifying the mechanisms of action and outcomes for this group, which we refer to as service user students. The Recovery Colleges Characterisation and Testing (RECOLLECT) study is a five-year (2020-2025) programme of research in England. The aim of RECOLLECT is to determine Recovery Colleges' effectiveness and cost-effectiveness, and identify organisational influences on fidelity and improvements in mental health outcomes. METHODS: RECOLLECT comprises i) a national survey of Recovery Colleges, ii) a prospective cohort study to establish the relationship between fidelity, mechanisms of action and psychosocial outcomes, iii) a prospective cohort study to investigate effectiveness and cost-effectiveness, iv) a retrospective cohort study to determine the relationship between Recovery College use and outcomes and mental health service use, and v) organisational case studies to establish the contextual and organisational factors influencing fidelity and outcomes. The programme has been developed with input from individuals who have lived experience of mental health problems. A Lived Experience Advisory Panel will provide input into all stages of the research. Discussion: RECOLLECT will provide the first rigorous evidence on the effectiveness and cost effectiveness of Recovery Colleges in England, to inform their prioritising, commissioning, and running. The validated RECOLLECT multilevel change model will confirm the active components of Recovery Colleges. The fidelity measure and evidence about the fidelity-outcome relationship will provide an empirically-based approach to develop Recovery Colleges, to maximise benefits for students. Findings will be disseminated through the study website (researchintorecovery.com/recollect) and via national and international Recovery College networks to maximise impact, and will shape policy on how Recovery Colleges can help those with mental health problems lead empowered, meaningful and fulfilling lives.

Rhythm versus rate control for atrial fibrillation in heart failure with preserved ejection fractionBackground: There are few prospective studies assessing the benefits of rhythm control of atrial fibrillation (AF) in patients with heart failure and preserved ejection fraction (HFpEF), which accounts for 50% of all heart failure patients. Objective: Conduct a meta-analysis to assess the effects of rhythm control (ablation and/or antiarrhythmic medications) vs rate control on all-cause mortality in AF patients with HFpEF. Methods: Databases were searched for studies reporting the effect of rhythm control vs rate control on mortality in patients with HFpEF (Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar, and EBSCO CINAHL). The search was not restricted to time or publication status. The primary endpoint was all-cause mortality. The minimum duration of follow-up required for inclusion was 1 year. Results: The literature search identified 1210 candidate studies; 5 studies and 16,825 patients were included. The study population had 57% men with a mean age of 71± 2.5 years. Rhythm control for AF was associated with lower all-cause mortality (odds ratio 0.735, 95% confidence interval 0.665-0.813; P < .001) as compared to rate control. Conclusion: Rhythm control for AF in patients with HFpEF was associated with decreased all-cause mortality.

Single-Center Experience With Liver Transplant Using Donors With Very High Transaminase LevelsOBJECTIVES: Elevation of transaminases has been used as a marker of hepatic ischemic injury and as a crucial parameter for liver graft assessment. However, analysis of serum transaminases has limitations regarding the quantitative assessment of liver necrosis and is not a reliable predictor of outcomes. MATERIALS AND METHODS: We retrospectively reviewed the medical records of all liver transplants (N = 238) performed at the UMass Memorial Medical Center from 2009 to 2013. RESULTS: Fourteen liver grafts showed high peak aminotransferases alanine aminotransferase (ALT) and aspartate aminotransferase (AST) at > 1000 U/L. This high aminotransferase group was compared with 224 donors with low transaminase levels (ALT/AST < 1000 U/L). The high transaminase donors had a median peak AST level of 3216 U/L (range, 1823-13?030 U/L) and ALT level of 2677 U/L (range, 812-7080 U/L). The high transaminase donors showed higher levels of lactate dehydrogenase, international normalized ratio, total bilirubin, and gamma-glutamyltransferase compared with low transaminase donors; however, only lactate dehydrogenase results reached statistical significance. None of the grafts from the high transaminase donors showed primary nonfunction. Three-year graft and patient survival rates were similar in both groups (75% vs 80% [P = .48] and 72% vs 82% [P = .33], respectively). In an analysis of the discard rate of livers over a 10-year period in the United States using the Scientific Registry of Transplant Recipients database, the discard rate of livers with high aminotransferase levels was 69.14% compared with 22.23% for livers with low transaminase levels. CONCLUSIONS: Liver grafts from donors with high transaminase levels can lead to clinical results that are similar to liver grafts from donors who had lower peak transaminase levels.

The influence of payor status on outcomes associated with surgical repair of upper gastrointestinal perforations due to peptic ulcer disease in the United StatesBACKGROUND: An association between lack of insurance and inferior outcomes has been well described for a number of surgical emergencies, yet little is known about the relationship of payor status and outcomes of patients undergoing emergent surgical repair for upper gastrointestinal (UGI) perforations. We evaluated the association of payor status and in-hospital mortality for patients undergoing emergency surgery for UGI perforations in the United States. METHODS: Nationwide Inpatient Sample (NIS) was queried to identify patients between 18 and 64 years of age who underwent emergent (open or laparoscopic) repair for UGI perforations secondary to peptic ulcer disease (2010-2014). Primary outcome was in-hospital mortality. Secondary outcomes were major and minor postoperative complications. The main predictor outcome was insurance status (Private, Medicaid, Uninsured). Univariate and multivariable regression analyses were performed. Data were weighted to provide national estimates. RESULTS: 21,005 patients underwent surgical repair for UGI perforations. Patients with private insurance represented the largest payor group (47%). After adjustment of other factors, payor status was not a statistically significant predictor of in-hospital mortality (Medicaid vs. Private: [OR] 1.1; 95% [CI] 0.67-1.81; Uninsured vs. Private: OR 0.9, 95% CI 0.52-1.61). However, payor status remained a statistically significant predictor of major postoperative complications (Medicaid vs. Private [OR] 1.4; 95% CI 1.1, 1.8; Uninsured vs. Private [OR]1.2, 95% CI 0.9, 1.5) and minor postoperative complications (Medicaid vs. Private [OR] 1.4; 95% CI 1.1, 1.9; Uninsured vs. Private [OR]1.2, 95% CI 0.9, 1.6). CONCLUSIONS: Emergency surgery for UGI perforations is associated with high mortality and morbidity across all payor classes; however, Medicaid is a predictor for both major and minor postoperative complications. Preventing perforation through preventative measures will be key to reducing the burden of peptic ulcer disease across all populations.
