Community health workers are increasingly recognized as useful for improving health care and health outcomes for a variety of chronic conditions. Community health workers can provide social support, ...navigation of health systems and resources, and lay counseling. Social and cultural alignment of community health workers with the population they serve is an important aspect of community health worker intervention. Although community health worker interventions have been shown to improve patient-centered outcomes in underserved communities, these interventions have not been evaluated with sickle cell disease. Evidence from other disease areas suggests that community health worker intervention also would be effective for these patients. Sickle cell disease is complex, with a range of barriers to multifaceted care needs at the individual, family/friend, clinical organization, and community levels. Care delivery is complicated by disparities in health care: access, delivery, services, and cultural mismatches between providers and families. Current practices inadequately address or provide incomplete control of symptoms, especially pain, resulting in decreased quality of life and high medical expense. The authors propose that care and care outcomes for people with sickle cell disease could be improved through community health worker case management, social support, and health system navigation. This paper outlines implementation strategies in current use to test community health workers for sickle cell disease management in a variety of settings. National medical and advocacy efforts to develop the community health workforce for sickle cell disease management may enhance the progress and development of “best practices” for this area of community-based care.
Abstract Background Recent studies have demonstrated relatively high rates of percutaneous coronary interventions (PCIs) classified as “inappropriate.” The New York State Department of Health shared ...rates with hospitals and announced the intention of withholding reimbursement pending demonstration of clinical rationale for Medicaid patients with inappropriate PCIs. Objectives The objective was to examine changes over time in the number and rate of inappropriate PCIs. Methods Appropriate use criteria were applied to PCIs performed in New York in patients without acute coronary syndromes or previous coronary artery bypass graft surgery in periods before (2010 through 2011) and after (2012 through 2014) efforts were made to decrease inappropriateness rates. Changes in the number of appropriate PCIs were also assessed. Results The percentage of inappropriate PCIs for all patients dropped from 18.2% in 2010 to 10.6% in 2014 (from 15.3% to 6.8% for Medicaid patients, and from 18.6% to 11.2% for other patients). The total number of PCIs in patients with no acute coronary syndrome/no prior coronary artery bypass graft surgery that were rated as inappropriate decreased from 2,956 patients in 2010 to 911 patients in 2014, a reduction of 69%. For Medicaid patients, the decrease was from 340 patients to 84 patients, a decrease of 75%. For a select set of higher-risk scenarios, there were higher numbers of appropriate PCIs per year in the period from 2012 to 2014. Conclusions The inappropriateness rate for PCIs and the use of PCI for elective procedures in New York has decreased substantially between 2010 and 2014. This decrease has occurred for a large proportion of PCI hospitals.
Background There is currently no systematic approach to evaluating the severity of intraoperative adverse events (iAEs). Study Design A 3-phase project was designed to develop and validate a novel ...severity classification scheme for iAEs. Phase 1 created the severity classification using a modified Delphi process. Phase 2 measured the classification's internal consistency by calculating inter-rater reliability among 91 surgeons using standardized iAEs scenarios. Phase 3 measured the classification's construct validity by testing whether major iAEs (severity class ≥3) correlated with worse 30-day postoperative outcomes compared with minor iAEs (severity class <3). This was achieved by creating a matched database using American College of Surgeons NSQIP and administrative data, querying for iAEs using the Patient Safety Indicator #15 (Accidental Puncture/Laceration), and iAE confirmation by chart review. Results Phase 1 resulted in a 6-point severity classification scheme. Phase 2 revealed an inter-rater reliability of 0.882. Of 9,292 patients, phase 3 included 181 confirmed with iAEs. All preoperative/intraoperative variables, including demographics, comorbidities, type of surgery performed, and operative length, were similar between patients with minor (n = 110) vs major iAEs (n = 71). In multivariable logistic analysis, severe iAEs correlated with higher risks of any postoperative complication (odds ratio OR = 3.8; 95% CI, 1.9−7.4; p < 0.001), surgical site infections (OR = 3.7; 95% CI, 1.7−8.2; p = 0.001), systemic sepsis (OR = 6.0; 95% CI, 2.1−17.2; p = 0.001), failure to wean off the ventilator (OR = 3.2; 95% CI, 1.2−8.9; p = 0.022), and postoperative length of stay ≥7 days (OR = 3.0; 95% CI, 1.5−5.9; p = 0.002). Thirty-day mortalities were similar (4.5% vs 7.1%; p = 0.46). Conclusions We propose a novel iAE severity classification system with high internal consistency and solid construct validity. Our classification scheme might prove essential for benchmarking quality of intraoperative care across hospitals and/or individual surgeons.
Summary Background Coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are alternative treatments for multivessel coronary disease. Although the procedures have been ...compared in several randomised trials, their long-term effects on mortality in key clinical subgroups are uncertain. We undertook a collaborative analysis of data from randomised trials to assess whether the effects of the procedures on mortality are modified by patient characteristics. Methods We pooled individual patient data from ten randomised trials to compare the effectiveness of CABG with PCI according to patients' baseline clinical characteristics. We used stratified, random effects Cox proportional hazards models to test the effect on all-cause mortality of randomised treatment assignment and its interaction with clinical characteristics. All analyses were by intention to treat. Findings Ten participating trials provided data on 7812 patients. PCI was done with balloon angioplasty in six trials and with bare-metal stents in four trials. Over a median follow-up of 5·9 years (IQR 5·0–10·0), 575 (15%) of 3889 patients assigned to CABG died compared with 628 (16%) of 3923 patients assigned to PCI (hazard ratio HR 0·91, 95% CI 0·82–1·02; p=0·12). In patients with diabetes (CABG, n=615; PCI, n=618), mortality was substantially lower in the CABG group than in the PCI group (HR 0·70, 0·56–0·87); however, mortality was similar between groups in patients without diabetes (HR 0·98, 0·86–1·12; p=0·014 for interaction). Patient age modified the effect of treatment on mortality, with hazard ratios of 1·25 (0·94–1·66) in patients younger than 55 years, 0·90 (0·75–1·09) in patients aged 55–64 years, and 0·82 (0·70–0·97) in patients 65 years and older (p=0·002 for interaction). Treatment effect was not modified by the number of diseased vessels or other baseline characteristics. Interpretation Long-term mortality is similar after CABG and PCI in most patient subgroups with multivessel coronary artery disease, so choice of treatment should depend on patient preferences for other outcomes. CABG might be a better option for patients with diabetes and patients aged 65 years or older because we found mortality to be lower in these subgroups.

We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one active galactic nucleus (AGN) (NGC 3227) from a 2014 campaign. ...Our main goals are (1) to determine the black hole masses from continuum-Hβ reverberation signatures, and (2) to look for velocity-dependent time delays that might be indicators of the gross kinematics of the broad-line region. We successfully measure Hβ time delays and black hole masses for five AGNs, four of which have previous reverberation mass measurements. The values measured here are in agreement with earlier estimates, though there is some intrinsic scatter beyond the formal measurement errors. We observe velocity-dependent Hβ lags in each case, and find that the patterns have changed in the intervening five years for three AGNs that were also observed in 2007.
To evaluate the early and late health-related quality of life (QOL) outcomes among prostate cancer patients following stereotactic body radiation therapy (SBRT).
Patient self-reported QOL was ...prospectively measured among 864 patients from phase 2 clinical trials of SBRT for localized prostate cancer. Data from the Expanded Prostate Cancer Index Composite (EPIC) instrument were obtained at baseline and at regular intervals up to 6 years. SBRT delivered a median dose of 36.25 Gy in 4 or 5 fractions. A short course of androgen deprivation therapy was given to 14% of patients.
Median follow-up was 3 years and 194 patients remained evaluable at 5 years. A transient decline in the urinary and bowel domains was observed within the first 3 months after SBRT which returned to baseline status or better within 6 months and remained so beyond 5 years. The same pattern was observed among patients with good versus poor baseline function and was independent of the degree of early toxicities. Sexual QOL decline was predominantly observed within the first 9 months, a pattern not altered by the use of androgen deprivation therapy or patient age.
Long-term outcome demonstrates that prostate SBRT is well tolerated and has little lasting impact on health-related QOL. A transient and modest decline in urinary and bowel QOL during the first few months after SBRT quickly recovers to baseline levels. With a large number of patients evaluable up to 5 years following SBRT, it is unlikely that unexpected late adverse effects will manifest themselves.
Summary Natalizumab is a new treatment option for patients with active relapsing-remitting multiple sclerosis. In phase III studies, natalizumab was highly effective and well tolerated; however, ...three cases of progressive multifocal leucoencephalopathy (PML) were identified (estimated incidence of one per 1000; 95% CI 0·2–2·8; mean treatment period 17·9 months). In this Review we summarise the current information on PML, the three confirmed cases of PML, and the results of an extensive safety assessment of all patients treated with natalizumab. On the basis of these reviews, we make recommendations for appropriate selection of candidates for natalizumab and pretreatment assessments. In addition, a three-step diagnostic and management algorithm was developed to monitor natalizumab-treated patients with multiple sclerosis for PML and other opportunistic infections. The algorithm includes strategies for clinical, MRI, and laboratory assessments. Maintaining clinical vigilance allows for early suspension of natalizumab in potential cases of PML, thereby increasing the opportunity for immune reconstitution, which may improve prognosis if PML is confirmed.

Abstract Background Few recent studies have compared the outcomes of coronary artery bypass graft (CABG) surgery with percutaneous coronary interventions (PCIs) in patients with isolated (single ...vessel) proximal left anterior descending (PLAD) coronary artery disease in the era of drug-eluting stents (DES). Objectives The goal of this study was to compare outcomes in patients with PLAD who underwent CABG and PCI with DES. Methods New York’s Percutaneous Coronary Interventions Reporting System was used to identify and track all patients who underwent CABG surgery and received DES for isolated PLAD disease between January 1, 2008 and December 31, 2010, and who were followed-up through December 31, 2011. A total of 5,340 of 6,064 (88%) patients received DES. Patients were matched to vital statistics data to obtain mortality after discharge and matched to New York’s administrative data to obtain readmissions for myocardial infarction (MI) and stroke. To minimize selection bias, patients were propensity matched into 715 CABG and/or DES pairs, and 3 outcome measures were compared across the pairs. Results Kaplan-Meier estimates for CABG and DES did not significantly differ for mortality or mortality, MI, and/or stroke, but repeat revascularization rates were lower for CABG (7.09% vs. 12.98%; p = 0.0007). After further adjustment with Cox proportional hazards models, there were still no significant differences in 3-year mortality rates (CABG and/or DES adjusted hazard ratio (AHR): 1.14; 95% confidence interval CI: 0.70 to 1.85) or mortality, MI, and/or stroke rates (AHR: 1.15; 95% CI: 0.76 to 1.73), and the repeat revascularization rate remained significantly lower for CABG patients (AHR: 0.54; 95% CI: 0.36 to 0.81). Conclusions Despite the higher rating in current guidelines of CABG (Class IIa vs. Class IIb) for patients with isolated PLAD disease, there were no differences in mortality or mortality, MI, and/or stroke, although CABG patients had significantly lower repeat revascularization rates.
