Most preoperative stress tests fail to comply with practice guideline indications and do not reduce cardiac events.

BACKGROUND: There is wide variation in stress test utilization before major vascular surgery and adherence to practice guidelines is unclear. We defined rates of stress test compliance at our institution and led a quality improvement initiative to improve compliance with American Heart Association (ACC/AHA) guidelines. METHODS: We implemented a stress testing order set in the electronic medical record at one tertiary hospital. We reviewed all patients who underwent elective, major vascular surgery in the 6 months before (Jan 1, 2022 - Jul 1, 2022) and 6 months after (Aug 1, 2022 - Jan 31, 2023) implementation. We studied stress test guideline compliance, changes in medical or surgical management, and major adverse cardiac events (MACE). RESULTS: Before order set implementation, 37/122 patients (30%) underwent stress testing within the past year (29 specifically ordered preoperatively) with 66% (19/29) guideline compliance. After order set implementation, 50/173 patients (29%) underwent stress testing within the past year (41 specifically ordered preoperatively) with 80% (33/41) guideline compliance. In the pre- and postimplementation cohorts, stress testing led to a cardiovascular medication change or preoperative coronary revascularization in 24% (7/29) and 27% (11/41) of patients, and a staged surgery or less invasive anesthetic strategy in 14% (4/29) and 4.9% (2/41) of patients, respectively. All unindicated stress tests were surgeon-ordered and none led to a change in management. There was no change in MACE after order set implementation. CONCLUSIONS: Electronic medical record-based guidance of perioperative stress testing led to a slight decrease in overall stress testing and an increase in guideline-compliant testing. Our study highlights a need for improved preoperative cardiovascular risk assessment prior to major vascular surgery, which may eliminate unnecessary testing and more effectively guide perioperative decision-making.

Data-driven collaborative QUality improvement in Cardiac Rehabilitation (QUICR) to increase program completion: protocol for a cluster randomized controlled trial.

BACKGROUND: Coronary heart disease (CHD) is the leading cause of deaths and disability worldwide. Cardiac rehabilitation (CR) effectively reduces the risk of future cardiac events and is strongly recommended in international clinical guidelines. However, CR program quality is highly variable with divergent data systems, which, when combined, potentially contribute to persistently low completion rates. The QUality Improvement in Cardiac Rehabilitation (QUICR) trial aims to determine whether a data-driven collaborative quality improvement intervention delivered at the program level over 12 months: (1) increases CR program completion in eligible patients with CHD (primary outcome), (2) reduces hospital admissions, emergency department presentations and deaths, and costs, (3) improves the proportion of patients receiving guideline-indicated CR according to national and international benchmarks, and (4) is feasible and sustainable for CR staff to implement routinely. METHODS: QUICR is a multi-centre, type-2, hybrid effectiveness-implementation cluster-randomized controlled trial (cRCT) with 12-month follow-up. Eligible CR programs (n = 40) and the individual patient data within them (n ~ 2,000) recruited from two Australian states (New South Wales and Victoria) are randomized 1:1 to the intervention (collaborative quality improvement intervention that uses data to identify and manage gaps in care) or control (usual care with data collection only). This sample size is required to achieve 80% power to detect a difference in completion rate of 22%. Outcomes will be assessed using intention-to-treat principles. Mixed-effects linear and logistic regression models accounting for clusters within allocated groupings will be applied to analyse primary and secondary outcomes. DISCUSSION: Addressing poor participation in CR by patients with CHD has been a longstanding challenge that needs innovative strategies to change the status-quo. This trial will harness the collaborative power of CR programs working simultaneously on common problem areas and using local data to drive performance. The use of data linkage for collection of outcomes offers an efficient way to evaluate this intervention and support the improvement of health service delivery. ETHICS: Primary ethical approval was obtained from the Northern Sydney Local Health District Human Research Ethics Committee (2023/ETH01093), along with site-specific governance approvals. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12623001239651 (30/11/2023) ( https://anzctr.org.au/Trial/Registration/TrialReview.aspx?id=386540&isReview=true ).

Potential impact of blood cholesterol guidelines on statin treatment in the U.S. population using interrupted time series analysis.

BACKGROUND: The 2013 ACC/AHA Guideline was a paradigm shift in lipid management and identified the four statin-benefit groups. Many have studied the guideline's potential impact, but few have investigated its potential long-term impact on MACE. Furthermore, most studies also ignored the confounding effect from the earlier release of generic atorvastatin in Dec 2011. METHODS: To evaluate the potential (long-term) impact of the 2013 ACC/AHA Guideline release in Nov 2013 in the U.S., we investigated the association of the 2013 ACC/AHA Guideline with the trend changes in 5-Year MACE survival and three other statin-related outcomes (statin use, optimal statin use, and statin adherence) while controlling for generic atorvastatin availability using interrupted time series analysis, called the Chow's test. Specifically, we conducted a retrospective study using U.S. nationwide de-identified claims and electronic health records from Optum Labs Database Warehouse (OLDW) to follow the trends of 5-Year MACE survival and statin-related outcomes among four statin-benefit groups that were identified in the 2013 ACC/AHA Guideline. Then, Chow's test was used to discern trend changes between generic atorvastatin availability and guideline potential impact. RESULTS: 197,021 patients were included (ASCVD: 19,060; High-LDL: 33,907; Diabetes: 138,159; High-ASCVD-Risk: 5,895). After the guideline release, the long-term trend (slope) of 5-Year MACE Survival for the Diabetes group improved significantly (P = 0.002). Optimal statin use for the ASCVD group also showed immediate improvement (intercept) and long-term positive changes (slope) after the release (P < 0.001). Statin uses did not have significant trend changes and statin adherence remained unchanged in all statin-benefit groups. Although no other statistically significant trend changes were found, overall positive trend change or no changes were observed after the 2013 ACC/AHA Guideline release. CONCLUSIONS: The 2013 ACA/AHA Guideline release is associated with trend improvements in the long-term MACE Survival for Diabetes group and optimal statin use for ASCVD group. These significant associations might indicate a potential positive long-term impact of the 2013 ACA/AHA Guideline on better health outcomes for primary prevention groups and an immediate potential impact on statin prescribing behaviors in higher-at-risk groups. However, further investigation is required to confirm the causal effect of the 2013 ACA/AHA Guideline.

Differences in provider approach to initiating and titrating guideline directed medical therapy in heart failure with reduced ejection fraction.

BACKGROUND: Despite the strong evidence supporting guideline-directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF), prescription rates in clinical practice are still lacking. METHODS: A survey containing 20 clinical vignettes of patients with HFrEF was answered by a national sample of 127 cardiologists and 68 internal/family medicine physicians. Each vignette had 4-5 options for adjusting GDMT and the option to make no medication changes. Survey respondents could only select one option. For analysis, responses were dichotomized to the answer of interest. RESULTS: Cardiologists were more likely to make GDMT changes than general medicine physicians (91.8% vs. 82.0%; OR 1.84 [1.07-3.19]; p = 0.020). Cardiologists were more likely to initiate beta-blockers (46.3% vs. 32.0%; OR 2.38 [1.18-4.81], p = 0.016), angiotensin receptor blocker/neprilysin inhibitor (ARNI) (63.8% vs. 48.1%; OR 1.76 [1.01-3.09], p = 0.047), and hydralazine and isosorbide dinitrate (HYD/ISDN) (38.2% vs. 23.7%; OR 2.47 [1.48-4.12], p < 0.001) compared to general medicine physicians. No differences were found in initiating angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARBs), initiating mineralocorticoid receptor antagonist (MRA), sodium-glucose transporter protein 2 (SGLT2) inhibitors, digoxin, or ivabradine. CONCLUSIONS: Our results demonstrate cardiologists were more likely to adjust GDMT than general medicine physicians. Future focus on improving GDMT prescribing should target providers other than cardiologists to improve care in patients with HFrEF.

A Bibliometric Analysis on Adherence to Reporting Standards for Endovascular Treatment of Chronic Lower Extremity Peripheral Artery Disease.

BACKGROUND: The treatment of chronic limb-threatening ischemia (CLTI) involves a broad spectrum of therapies including many new and emerging techniques. To standardize the results of studies examining this pathology and to allow critical analysis and comparison between studies, the Society for Vascular Surgery (SVS) recommended reporting standard guidelines for the endovascular management of CLTI in 2016. Research studies that do not adhere to complete reporting standards are often more ambiguous in impact and external validity, leading to bias and misinformation that has potentially damaging effects on clinical decision-making. We thus sought to examine adherence to and factors associated with noncompliance with these recommended guidelines. METHODS: A literature database search was conducted to include all clinical trials, randomized controlled trials, and retrospective comparative studies written in English examining the endovascular treatment of peripheral artery disease (PAD)/CLTI from January 2020 to August 2022. Systematic reviews, case reports, and meta-analysis were excluded. The manuscripts were reviewed for adherence with the SVS guidelines (overall and by guideline subcategories based on demographics, treatment methods, and outcomes), and factors associated with this adherence were determined. These data were used to calculate descriptive and comparative statistics. RESULTS: Fifty-four manuscripts were identified from this time frame. On average, articles reviewed reported on 42.0% of the SVS reporting standards (range, 25.0-65.2%, Fig 1) with 74.1% of articles (n = 40) not adhering to at least 50.0% of the standards. Manuscripts most completely followed guidelines regarding "patient factors" and were least likely to demonstrate adherence to the description of CLTI and study complications. Within the guideline subcategories, complete adherence to guidelines was not demonstrated in any manuscript in stent trials, disease outcome measures, technical outcome measures, patient factors and critical limb ischemia description, and complete adherence rates within the other subcategories was low (range, 5.6-18.6%). Studies conducted within the United States and those with industry sponsorship were more likely to adhere to >50% of the reporting standards (P < 0.05). Journal impact factor, year of publication, and number of authors had no correlation to the percent adherence to guidelines in specific categories or adherence overall. CONCLUSIONS: Adherence to reporting standard guidelines for endovascular treatment of lower extremity PAD specifically outlined by the SVS is suboptimal regardless of the quality of the journal the research is published in. Increasing adherence to reporting standards to provide a framework for comparison of studies across techniques used should be prioritized by authors, journal editors, and vascular societies.

Lessons Learned from Coronary Revascularization Appropriateness Statements for Application to Peripheral Artery Disease.

Appropriate Use Criteria (AUC) are evidence-based criteria developed in a methodologically robust manner with the input of expert providers across a wide range of disciplines and practice settings. AUC have been successfully implemented in the diagnosis and management of a wide range of cardiovascular disease processes. AUC have demonstrated clear potential for influencing meaningful change in practice patterns with regards to high-value, high-quality care in cardiovascular pathologies. Potential for similar impact in the management of peripheral artery disease, specifically for patients presenting with intermittent claudication (IC), may be limited due to unique challenges. These challenges include multidisciplinary interventionalists, variability in existing AUC across specialties, and financial incentives influencing physician behavior. AUC serve to benefit patients by improving outcomes, and adoption of AUC is a critical step toward improving the quality of care provided to patients with IC. Societal support is necessary for effective AUC implementation.

Improving delirium assessments in acute senior health: A quality improvement project for care of the older person.

BACKGROUND: Delirium is a common and reversible neurobehavioral condition with significant morbidity and mortality ramifications for older patients. Consequentially, clear guidelines exist pertaining to its swift identification and management. However, studies suggest that adherence to these guidelines are poor. This audit aimed to evaluate compliance to the National Institute for Health and Care Excellence's (NICE) delirium guidelines in an Acute Senior Health Unit (ASHU) and to present a single centre experience of a low-cost ward-based intervention for improving delirium guideline adherence. METHODS: A retrospective observational audit was conducted on patients admitted to ASHU between 01/07/2023 and 30/07/2023. Data on delirium assessments, diagnoses and causes of delirium were obtained through retrospective database searches. Posters and education based multidisciplinary team (MDT) interventions were designed and initiated following grounded thematic literature analysis and ward discussion. A methodically equivalent audit was then conducted between 01/09/2023 and 30/09/23. Data was anonymised and blinded and analysis was performed on SPSS V12.0. RESULTS: A total of 128 patients were included in the study. Initial audit revealed suboptimal compliance with NICE recommendations. Chi-square test of independence found that patients were statistically more likely to receive a full delirium assessment (1.9% vs. 56.6%, p = 0.001) and formal diagnosis (5.8% vs. 27.6%, p = 0.002) after the ward-based intervention. CONCLUSION: This study provides limited evidence in favour of low-cost MDT based interventions for improving adherence to NICE delirium guidelines and provides a 5-step framework for future studies. This study also explores the potential patient implications of these interventions. A repeat audit should be conducted to ensure lasting and sustainable change is achieved. TRIAL REGISTRATION/CLINICAL TRIAL NUMBER: AUDI003614.

Physiotherapists' adherence to Clinical Practice Guidelines in fibromyalgia: a cross-sectional online survey.

To evaluate the level of knowledge and adherence to Clinical Practice Guidelines on fibromyalgia of physiotherapists in Spain. A cross-sectional study using an ad-hoc online survey was implemented to assess aspects on the assessment, treatment, and decision of the length of the therapeutic approach on fibromyalgia. Based on the results, professionals were classified as adherent, partially adherent, or non-adherent. The level of agreement with several statements on the condition was also evaluated across the professionals surveyed to evaluate the potential consensus. A total of 240 physiotherapists met inclusion criteria, amongst which 68 (28.33%) were adherent. The academic level of studies (Chi-square = 48.601, p-value = 0.001) and having had previous training in fibromyalgia (Chi-square = 151.011, p-value = 0.001) displayed statistically significant differences across adherence-based groups. Consensus was reached for 15 out of 24 statements. Our findings highlight the presence of an acceptable level of knowledge and adherence to clinical practice guidelines in the field of fibromyalgia among physiotherapists in Spain.Practice implicationsOur results also reveal the existence of an evidence-to-practice gap in the field, with potential room for improvement: further efforts on promoting and reinforcing the importance of evidence-based therapies are needed, from university teaching plans to clinical updates for daily practice.

Interprofessional teams with and without nurse practitioners and the level of adherence to best practice guidelines in cardiac surgery: A retrospective study.

AIM: To examine the level of adherence to best-practice guidelines of interprofessional teams with acute care nurse practitioners (ACNPs) compared to interprofessional teams without ACNPs. DESIGN: A retrospective observational study was conducted in 2023. METHOD: A retrospective cohort was created including 280 patients who underwent a coronary artery bypass graft and/or a valve repair and hospitalised in a cardiac surgery unit of a university affiliated hospital in Québec (Canada) between 1 January 2019 to 31 January 2020. The level of adherence to best-practice guidelines was measured from a composite score in percentage. The composite score was created from a newly developed tool including 99 items across six categories (patient information, pharmacotherapy, laboratory tests, post-operative assessment, patient and interprofessional teams' characteristics). Multivariate linear and logistic regression models were computed to examine the effect of interprofessional teams with ACNPs on the level of adherence to best-practice guidelines. RESULTS: Most of the patients of the cohort were male and underwent a coronary artery bypass graft procedure. Patients under the care of interprofessional teams with ACNP were 1.72 times more likely to reach a level of adherence higher than 80% compared to interprofessional teams without ACNPs and were 2.29 times more likely to be within the highest quartile of the scores for the level of adherence to best-practice guidelines of the cohort. IMPACT: This study provides empirical data supporting the benefits of ACNP practice for patients, interprofessional teams and healthcare organisations. RELEVANCE FOR PRACTICE: Our findings identify the important contributions of interprofessional teams that include ACNPs using a validated instrument, as well as their contribution to the delivery of high quality patient care. REPORTING METHOD: This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: Guidelines for reporting observational studies guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Evaluating antibiotic prophylaxis adherence: Implications for surgical site infections and wound care management.

AIM: This study aimed to evaluate adherence to an antibiotic prophylaxis protocol and its impact on incidence of surgical site infection (SSI). MATERIALS AND METHOD: A prospective observational cohort study was conducted at a teaching hospital in São Paulo, Brazil, from September to November 2015. The population were adults who underwent surgery with surgical antibiotic prophylaxis. The main outcomes measured were incidence of SSI at 30-days postoperatively, protocol adherence and surgical wound complications. STROBE guidelines were followed. RESULTS: Among the 527 participants recruited, a 30-day follow-up was completed by 78.7 % (n = 415). Within this cohort, 57.6 % were females aged over 60 years (36.4 %). The incidence of SSI stood at 9.4 % (n = 39), with dehiscence being the most prevalent complication at 64.1 % (n = 25), followed by increased exudate at 51.3 % (n = 20). Notably, full adherence to the antibiotic prophylaxis protocol was low at 1.7 % (n = 7). The study observed a 60 % increased risk of SSI for every protocol mistake made. Alarmingly, 17.8 % (n = 74) of participants received antibiotic treatment exceeding the stipulated protocol duration. The overall mortality rate stood at 13.5 % (n = 56), with 1 % (n = 4) of these deaths attributed to SSI. CONCLUSION: There is a pressing global necessity to enhance antibiotic management, as underscored by this study's revelation of low adherence to the antibiotic prophylaxis protocol. This lack of adherence correlated with a notable incidence of SSI and subsequent wound complications. Nearly 20 % of participants received prolonged antibiotic treatment. Adhering strictly to the protocol could substantially impact SSI-related outcomes and enhance global antibiotic management.

Indication-based and patient-based hand hygiene performance among nurses working at a university hospital.

The traditional method of monitoring hand hygiene (HH) based on specific indications does not ensure that HH is performed for all required indications during patient care. This study aimed to compare HH performance rates (HHPRs) based on specific indications versus overall patient care among nurses at a university hospital. The study retrospectively analyzed HH monitoring data for 1398 indications from 543 patients and 190 nurses. Observations were conducted continuously, tracking a single healthcare worker from before patient contact until the end of the contact within a 30-min period. The indication-based HHPR was found to be 89.1%, while the patient-based HHPR was 78.1%. In the context of patient-based HHPR, the lowest rates were observed among nurses in the emergency room (48.3%) and those with less than 1 year of work experience (66.7%). Moreover, the largest discrepancy between indication-based and patient-based HHPR was noted among emergency room nurses with less than 1 year of experience. This significant difference underscores the need for patient-based HH monitoring, particularly for nurses in emergency settings and those with limited experience.

Adherence to suicide reporting guidelines by news shared on a social networking platform.

Rates of suicide in the United States are at a more than 20-y high. Suicide contagion, or spread of suicide-related thoughts and behaviors through exposure to sensationalized and harmful content is a well-recognized phenomenon. Health authorities have published guidelines for news media reporting on suicide to help prevent contagion; however, uptake of recommendations remains limited. A key barrier to widespread voluntary uptake of suicide-reporting guidelines is that more sensational content is perceived to be more engaging to readers and thus enhances publisher visibility and engagement; however, no empirical information exists on the actual influence of adherence to safe-reporting practices on reader engagement. Hence, we conducted a study to analyze adherence to suicide-reporting guidelines on news shared on social media and to assess how adherence affects reader engagement. Our analysis of Facebook data revealed that harmful elements were prevalent in news articles about suicide shared on social media while the presence of protective elements was generally rare. Contrary to popular perception, closer adherence to safe-reporting practices was associated with a greater likelihood of an article being reshared (adjusted odds ratio [AOR] = 1.19, 95% confidence interval [CI] = 1.10 to 1.27) and receiving positive engagement ("love" reactions) (AOR = 1.20, 95% CI = 1.13 to 1.26). Mean safe-reporting scores were lower in the US than other English-speaking nations and variation existed by publisher characteristics. Our results provide empirical evidence that improved adherence to suicide-reporting guidelines may benefit not only the health of individuals, but also support publisher goals of reach and engagement.

Use of Hepatocellular Carcinoma Surveillance in Patients With Cirrhosis: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) surveillance is associated with early tumor detection and improved survival; however, it is often underused in clinical practice. We aimed to characterize surveillance use among patients with cirrhosis and the efficacy of interventions to increase surveillance. APPROACH AND RESULTS: We performed a systematic literature review using the MEDLINE database from January 2010 through August 2018 to identify cohort studies evaluating HCC surveillance receipt or interventions to increase surveillance in patients with cirrhosis. A pooled estimate for surveillance receipt with 95% confidence intervals was calculated. Correlates of surveillance use were defined from each study and prespecified subgroup analyses. Twenty-nine studies, with a total of 118,799 patients, met inclusion criteria, with a pooled estimate for surveillance use of 24.0% (95% confidence interval, 18.4-30.1). In subgroup analyses, the highest surveillance receipt was reported in studies with patients enrolled from subspecialty gastroenterology/hepatology clinics and lowest in studies characterizing surveillance in population-based cohorts (73.7% versus 8.8%, P < 0.001). Commonly reported correlates of surveillance included higher receipt among patients followed by subspecialists and lower receipt among those with alcohol-associated or nonalcoholic steatohepatitis (NASH)-related cirrhosis. All eight studies (n = 5,229) evaluating interventions including patient/provider education, inreach (e.g., reminder and recall systems), and population health outreach strategies reported significant increases (range 9.4%-63.6%) in surveillance receipt. CONCLUSIONS: HCC surveillance remains underused in clinical practice, particularly among patients with alcohol-associated or NASH-related cirrhosis and those not followed in subspecialty gastroenterology clinics. Interventions such as provider education, inreach including reminder systems, and population health outreach efforts can significantly increase HCC surveillance.

STEP-WISE APPROACH TO THE MANAGEMENT OF SUBMACULAR HEMORRHAGE USING PNEUMATIC DISPLACEMENT AND VITRECTOMY: The Manchester Protocol.

PURPOSE: To evaluate a sequential approach of pneumatic displacement followed by vitrectomy (pars plana vitrectomy) in failed cases to deal with submacular hemorrhage (SMH) of various etiologies. METHODS: Retrospective, nonrandomized interventional case series of consecutive patients with SMH of up to 2 weeks' duration, who were treated with a stepwise approach. Step 1 involved intravitreal injection of 0.3 mL 100% C3F8 and recombinant tissue plasminogen activator 50 µg/0.1 mL. If unsuccessful, a prompt pars plana vitrectomy with subretinal recombinant tissue plasminogen activator 50 µg/0.1 mL and 20% SF6 gas tamponade was performed as a second attempt to displace the SMH. RESULTS: Thirty-one patients with SMH underwent pneumatic displacement; 24 (77.4%) had a successful outcome without further intervention. The mean presenting visual acuity of the "successful cohort" was 1.34 logMAR (20/440 Snellen), improving to 0.83 logMAR (20/135 Snellen) 1 month after treatment. Five of the seven patients with failed pneumatic displacement underwent pars plana vitrectomy with subretinal recombinant tissue plasminogen activator at an average of 5 days poststep 1, with successful SMH displacement in 3 patients, giving an overall success of 87.1% for this treatment protocol. CONCLUSION: A sequential approach of expansile gas injection followed by prompt pars plana vitrectomy, aided by recombinant tissue plasminogen activator at both steps, is a coherent, logical pathway to treat SMH with high anatomical and functional success.

Compliance With Preferred Reporting Items for Systematic Review and Meta-Analysis Individual Participant Data Statement for Meta-Analyses Published for Stroke Studies.

Background and Purpose: Individual-participant data meta-analyses (IPD-MA) are powerful evidence synthesis studies which are considered the gold-standard of MA. The quality of reporting in these studies is guided by the 2015 Preferred Reporting Items for Systematic Review and Meta-Analysis of Individual Participant Data (PRISMA-IPD) guidelines. The growing number of IPD-MA published for stroke studies calls for an assessment of the compliance of these studies with the PRISMA-IPD statement. Methods: PubMed and EMBASE were searched for MA in stroke published between January 1, 2016, and March 30, 2020, in journals with impact factor >2. Literature reviews, scoping reviews, and aggregate MA were excluded. The final articles were scored using the 31-item PRISMA-IPD checklist. Results were depicted using descriptive statistics. Compliance with each item in PRISM-IPD guideline was recorded. The study was defined as compliant to IPD analyses if it satisfied all IPD specific items. Results: From an initial set of 321 articles, 31 met the final eligibility for data extraction. Only 4 (13%) described the use of PRISMA-IPD guidelines in their methodology, while 8/31 (26%) used the old PRISMA guidelines and 19/31 (61%) followed none. Regardless of mention of using IPD specific guidelines, 42% (n=13) of studies were compliant with all 4 IPD specific domains. The poorest areas of compliance were bias assessment within (32%) and across (39%) studies, reporting protocol and registration (42%), and reporting of IPD integrity (48%). The median journal impact factor was similar between the compliant (median, 8.1 [interquartile range, 5.4­39.9]) and noncompliant (median, 6 [interquartile range, 4.5­16.2]) groups (P=0.24). Similarly, the journal, country of correspondence, number of authors, number of studies included in MA, study sample size, and funding source were statistically similar between the groups. Conclusions: For the published IPD-MA stroke studies, the compliance with PRISMA-IPD statement and compliance with 4 IPD specific items was suboptimal. The journal, author, and study-related factors were not associated with compliance. Additional scrutiny measures to ensure adherence to mandated guidelines might increase the compliance. Several avenues to improve compliance and ensure optimal adherence are discussed.

Adherence to Lung-Protective Ventilation Principles in Pediatric Acute Respiratory Distress Syndrome: A Pediatric Acute Respiratory Distress Syndrome Incidence and Epidemiology Study.

OBJECTIVES: To describe mechanical ventilation management and factors associated with nonadherence to lung-protective ventilation principles in pediatric acute respiratory distress syndrome. DESIGN: A planned ancillary study to a prospective international observational study. Mechanical ventilation management (every 6 hr measurements) during pediatric acute respiratory distress syndrome days 0-3 was described and compared with Pediatric Acute Lung Injury Consensus Conference tidal volume recommendations (< 7 mL/kg in children with impaired respiratory system compliance, < 9 mL/kg in all other children) and the Acute Respiratory Distress Syndrome Network lower positive end-expiratory pressure/higher Fio2 grid recommendations. SETTING: Seventy-one international PICUs. PATIENTS: Children with pediatric acute respiratory distress syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Analyses included 422 children. On pediatric acute respiratory distress syndrome day 0, median tidal volume was 7.6 mL/kg (interquartile range, 6.3-8.9 mL/kg) and did not differ by pediatric acute respiratory distress syndrome severity. Plateau pressure was not recorded in 97% of measurements. Using delta pressure (peak inspiratory pressure - positive end-expiratory pressure), median tidal volume increased over quartiles of median delta pressure (p = 0.007). Median delta pressure was greater than or equal to 18 cm H2O for all pediatric acute respiratory distress syndrome severity levels. In severe pediatric acute respiratory distress syndrome, tidal volume was greater than or equal to 7 mL/kg 62% of the time, and positive end-expiratory pressure was lower than recommended by the positive end-expiratory pressure/Fio2 grid 70% of the time. In multivariable analysis, tidal volume nonadherence was more common with severe pediatric acute respiratory distress syndrome, fewer PICU admissions/yr, non-European PICUs, higher delta pressure, corticosteroid use, and pressure control mode. Adherence was associated with underweight stature and cuffed endotracheal tubes. In multivariable analysis, positive end-expiratory pressure/Fio2 grid nonadherence was more common with higher pediatric acute respiratory distress syndrome severity, ventilator decisions made primarily by the attending physician, pre-ICU cardiopulmonary resuscitation, underweight stature, and age less than 2 years. Adherence was associated with respiratory therapist involvement in ventilator management and longer time from pediatric acute respiratory distress syndrome diagnosis. Higher nonadherence to tidal volume and positive end-expiratory pressure recommendations were independently associated with higher mortality and longer duration of ventilation after adjustment for confounding variables. In stratified analyses, these associations were primarily influenced by children with severe pediatric acute respiratory distress syndrome. CONCLUSIONS: Nonadherence to lung-protective ventilation principles is common in pediatric acute respiratory distress syndrome and may impact outcome. Modifiable factors exist that may improve adherence.

Endovascular interventions for claudication do not meet minimum standards for the Society for Vascular Surgery efficacy guidelines.

OBJECTIVE: Because the treatment of intermittent claudication (IC) is elective, good short- and long-term outcomes are imperative. The objective of the present study was to examine the outcomes of endovascular management of IC reported in the Vascular Quality Initiative and compare them with the Society for Vascular Surgery guidelines for IC treatment to determine whether real-world results are within the guidelines. METHODS: Patients undergoing peripheral vascular intervention for IC from 2004 to 2017 with complete data and >9 month follow-up were included. The primary outcome measures were IC recurrence and repeat procedures performed ≤2 years after the initial treatment. RESULTS: A total of 16,152 patients met the inclusion criteria, with a mean age of 66 years. Of the 16,152 patients, 61% were men, 45% were current smokers, and 28% had been discharged without antiplatelet or statin medication. Adjusted analyses revealed that treatment of more than two arteries was associated with a shorter time to IC recurrence (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.09-1.31) and a shorter time to repeat procedures (HR, 1.25; 95% CI, 1.09-1.45). The use of atherectomy was also associated with a shorter time to IC recurrence (HR, 1.29; 95% CI, 1.08-1.33) and a shorter time to repeat procedures (HR, 1.31; 95% CI, 1.13-1.52). Discharge with antiplatelet and statin medications was associated with a longer time to IC recurrence (HR, 0.84; 95% CI, 0.78-0.91) and a longer time to repeat procedures (HR, 0.77; 95% CI, 0.69-0.87). Life-table analysis at 2 years revealed that only 32% of patients were free from IC recurrence, although 76% had not undergone repeat procedures. Stratified by anatomic treatment level, 37% of isolated aortoiliac interventions, 22% of aortoiliac and femoropopliteal interventions, 30% of isolated femoropopliteal interventions, and 20% of femoropopliteal and tibial interventions had remained free from IC recurrence at 2 years. CONCLUSIONS: Most patients treated with an endovascular approach to IC did not meet the Society for Vascular Surgery guidelines for long-term freedom from recurrent symptoms of >50% at 2 years. Many lacked preprocedure optimization of medical management. The use of atherectomy and treatment of more than two arteries were associated with poor outcomes after peripheral vascular intervention for IC, because only 32% of these patients were free from recurrent symptoms at 2 years. Even when risk factor modification is optimized before the procedure, vascular specialists should be aware of the association between atherectomy and multivessel interventions with poorer long-term outcomes and counsel patients appropriately before intervention.

Differences in cervical cancer screening and follow-up for black and white women in the United States.

OBJECTIVE: To study differences in screening adherence and follow-up after an abnormal Pap test in Non-Hispanic Black (Black) and Non-Hispanic White (White) women. METHODS: An observational cohort study using 2010 National Health Interview Survey cancer module to examine HPV knowledge, screening behavior, and follow-up to abnormal Pap test in Black and White women 18 years of age or older without a hysterectomy. We fit logistic regression models to examine associations between race and primary outcome variables including: HPV awareness, Pap test in the last three years, provider recommended Pap test, received Pap test results, had an abnormal Pap test, recommended follow-up, and adhered to the recommendation for follow-up. RESULTS: Analyzing data for 7509 women, Black women had lower odds ratios [OR] for: 1) HPV awareness (71% vs 83%; OR = 0.42; 95% CI = 0.36-0.49); 2) reporting Pap screening was recommended (59% vs 64%; OR = 0.76; 95% CI = 0.66-0.88), and 3) acknowledging receipt of Pap results (92% vs 94%; OR = 0.64; 95% CI = 0.49-0.83). Group differences persisted after covariates adjustment. In adjusted models, Black women had higher odds of reporting recent Pap screening (84% vs 77%; OR = 1.7; 95% CI = 1.42-2.03), but reported lower odds of receiving a follow-up recommendation subsequent to abnormal test (78% vs 87%; OR = 0.54; 95% CI = 0.31-0.95). CONCLUSION: Black women reported higher cervical cancer screening adherence but lower rates of being informed of an abnormal Pap test and contacted for follow-up treatment. We recommend a multilevel approach to deliver culturally appropriate education and communication for patients, physicians, clinicians in training, and clinic level ancillary staff.

Adherence in Hypertension.

The global epidemic of hypertension is largely uncontrolled and hypertension remains the leading cause of noncommunicable disease deaths worldwide. Suboptimal adherence, which includes failure to initiate pharmacotherapy, to take medications as often as prescribed, and to persist on therapy long-term, is a well-recognized factor contributing to the poor control of blood pressure in hypertension. Several categories of factors including demographic, socioeconomic, concomitant medical-behavioral conditions, therapy-related, healthcare team and system-related factors, and patient factors are associated with nonadherence. Understanding the categories of factors contributing to nonadherence is useful in managing nonadherence. In patients at high risk for major adverse cardiovascular outcomes, electronic and biochemical monitoring are useful for detecting nonadherence and for improving adherence. Increasing the availability and affordability of these more precise measures of adherence represent a future opportunity to realize more of the proven benefits of evidence-based medications. In the absence of new antihypertensive drugs, it is important that healthcare providers focus their attention on how to do better with the drugs they have. This is the reason why recent guidelines have emphasize the important need to address drug adherence as a major issue in hypertension management.

Bone evaluation in paediatric chronic kidney disease: clinical practice points from the European Society for Paediatric Nephrology CKD-MBD and Dialysis working groups and CKD-MBD working group of the ERA-EDTA.

Mineral and bone disorder (MBD) is widely prevalent in children with chronic kidney disease (CKD) and is associated with significant morbidity. CKD may cause disturbances in bone remodelling/modelling, which are more pronounced in the growing skeleton, manifesting as short stature, bone pain and deformities, fractures, slipped epiphyses and ectopic calcifications. Although assessment of bone health is a key element in the clinical care of children with CKD, it remains a major challenge for physicians. On the one hand, bone biopsy with histomorphometry is the gold standard for assessing bone health, but it is expensive, invasive and requires expertise in the interpretation of bone histology. On the other hand, currently available non-invasive measures, including dual-energy X-ray absorptiometry and biomarkers of bone formation/resorption, are affected by growth and pubertal status and have limited sensitivity and specificity in predicting changes in bone turnover and mineralization. In the absence of high-quality evidence, there are wide variations in clinical practice in the diagnosis and management of CKD-MBD in childhood. We present clinical practice points (CPPs) on the assessment of bone disease in children with CKD Stages 2-5 and on dialysis based on the best available evidence and consensus of experts from the CKD-MBD and Dialysis working groups of the European Society for Paediatric Nephrology and the CKD-MBD working group of the European Renal Association-European Dialysis and Transplant Association. These CPPs should be carefully considered by treating physicians and adapted to individual patients' needs as appropriate. Further areas for research are suggested.
