Early Initiation of Sacubitril/Valsartan in Patients With Acute Heart Failure and Renal Dysfunction: An Analysis of the TRANSITION Study.

BACKGROUND: Treatment of patients with heart failure with reduced ejection fraction (HFrEF) and renal dysfunction (RD) is challenging owing to the risk of further deterioration in renal function, especially after acute decompensated HF (ADHF). METHODS AND RESULTS: We assessed the effect of RD (estimated glomerular filtration rate of ≥30 to <60 mL/min/1.73 m2) on initiation, up-titration, and tolerability of sacubitril/valsartan in hemodynamically stabilized patients with HFrEF admitted for ADHF (RD, n = 476; non-RD, n = 483). At week 10, the target dose of sacubitril/valsartan (97/103 mg twice daily) was achieved by 42% patients in RD subgroup vs 54% in non-RD patients (P < .001). Sacubitril/valsartan was associated with greater estimated glomerular filtration rate improvements in RD subgroup than non-RD (change from baseline least squares mean 4.1 mL/min/1.73 m2, 95% confidence interval 2.2-6.1, P < .001). Cardiac biomarkers improved significantly in both subgroups; however, compared with the RD subgroup, the improvement was greater in those without RD (N-terminal pro-brain natriuretic peptide, -28.6% vs -44.8%, high-sensitivity troponin T -20.3% vs -33.9%) (P < .001). Patients in the RD subgroup compared with those without RD experienced higher rates of hyperkalemia (16.3% vs 6.5%, P < .001), investigator-reported cardiac failure (9.7% vs 5.6%, P = .029), and renal impairment (6.4% vs 2.1%, P = .002). CONCLUSIONS: Most patients with HFrEF and concomitant RD hospitalized for ADHF tolerated early initiation of sacubitril/valsartan and showed significant improvements in estimated glomerular filtration rate and cardiac biomarkers.

[Diagnosis and treatment of acute ischemic insults]. / Diagnose und Therapie des akuten ischämischen Insults.

In cases of stroke a distinction is made between a transient ischemic attack (TIA), a manifest ischemic infarction and cerebral hemorrhage. Cerebral ischemia can be caused by large vessel disease, small vessel disease, embolic causes, rare causes or stroke of unknown etiology. Acute diagnostic tests include a neurological examination, computed tomography (CT) and/or magnetic resonance imaging (MRI) with angiography, electrocardiography (ECG), and laboratory tests. The basic treatment of patients with TIA or acute ischemic infarction is performed in the stroke unit and includes monitoring of respiratory function, cardiac function, treatment of potential heart failure, detection of swallowing disorders, prophylaxis of thromboembolism, control of blood pressure and elevated blood sugar levels, and lowering of elevated body temperature. In patients with cardioembolic infarction, oral anticoagulation is initiated depending on the severity of the stroke and the size of the stroke on imaging.

Automatic Holter electrocardiogram analysis in ischaemic stroke patients to detect paroxysmal atrial fibrillation: ready to replace physicians?

BACKGROUND AND PURPOSE: The detection of paroxysmal atrial fibrillation (pAF) in patients presenting with ischaemic stroke shifts secondary stroke prevention to oral anticoagulation. In order to deal with the time- and resource-consuming manual analysis of prolonged electrocardiogram (ECG)-monitoring data, we investigated the effectiveness of pAF detection with an automated algorithm (AA) in comparison to a manual analysis with software support within the IDEAS study [study analysis (SA)]. METHODS: We used the dataset of the prospective IDEAS cohort of patients with acute ischaemic stroke/transient ischaemic attack presenting in sinus rhythm undergoing prolonged 72-h Holter ECG with central adjudication of atrial fibrillation (AF). This adjudicated diagnosis of AF was compared with a commercially available AA. Discordant results with respect to the diagnosis of pAF were resolved by an additional cardiological reference confirmation. RESULTS: Paroxysmal AF was finally diagnosed in 62 patients (5.9%) in the cohort (n = 1043). AA more often diagnosed pAF (n = 60, 5.8%) as compared with SA (n = 47, 4.5%). Due to a high sensitivity (96.8%) and negative predictive value (99.8%), AA was able to identify patients without pAF, whereas abnormal findings in AA required manual review (specificity 96%; positive predictive value 60.6%). SA exhibited a lower sensitivity (75.8%) and negative predictive value (98.5%), and showed a specificity and positive predictive value of 100%. Agreement between the two methods classified by kappa coefficient was moderate (0.591). CONCLUSION: Automated determination of 'absence of pAF' could be used to reduce the manual review workload associated with review of prolonged Holter ECG recordings.

Atrial fibrillation is frequent but does not affect risk stratification in pulmonary embolism.

BACKGROUND: Although prior studies indicate a high prevalence of atrial fibrillation (AF) in patients with pulmonary embolism (PE), the exact prevalence and prognostic impact are unknown. METHODS: We aimed to investigate the prevalence, risk factors and prognostic impact of AF on risk stratification, in-hospital adverse outcomes and mortality in 528 consecutive PE patients enrolled in a single-centre registry between 09/2008 and 09/2017. RESULTS: Overall, 52 patients (9.8%) had known AF and 57 (10.8%) presented with AF on admission; of those, 34 (59.6%) were newly diagnosed with AF. Compared to patients with no AF, overt hyperthyroidism was associated with newly diagnosed AF (OR 7.89 [2.99-20.86]), whilst cardiovascular risk comorbidities were more frequently observed in patients with known AF. Patients with AF on admission had more comorbidities, presented more frequently with tachycardia and elevated cardiac biomarkers and were hence stratified to higher risk classes. However, AF on admission had no impact on in-hospital adverse outcome (8.3%) and in-hospital mortality (4.5%). In multivariate logistic regression analyses corrected for AF on admission, NT-proBNP and troponin elevation as well as higher risk classes in risk assessment models remained independent predictors of an in-hospital adverse outcome. CONCLUSION: Atrial fibrillation is a frequent finding in PE, affecting more than 10% of patients. However, AF was not associated with a higher risk of in-hospital adverse outcomes and did not affect the prognostic performance of risk assessment strategies. Thus, our data support the use of risk stratification tools for patients with acute PE irrespective of the heart rhythm on admission.

[Embolic stroke of undetermined source (ESUS) : How much monitoring is necessary?] / ESUS ("embolic stroke of undetermined source") : Wie viel Monitoring ist nötig?

The clinical construct of embolic stroke of unknown source (ESUS) was first described in 2014. It is defined as cryptogenic ischemic stroke after the exclusion of a lacunar infarct, a significant (≥50%) stenosis of extracranial or intracranial arteries and a cardiac source of embolism. Initially, there was hope that these patients would benefit from anticoagulation. This was based on the suspicion that imaging criteria of stroke mimic features of embolism from cardiac sources or the great arteries. In two large randomized trials with 12,600 patients neither rivaroxaban nor dabigatran could reduce the risk of recurrent stroke. Based on these results, current research is focused on paroxysmal atrial fibrillation as a potential cause of stroke in these patients. Several randomized trials could show that by prolongation of monitoring to 30 days atrial fibrillation can be detected in approximately 10% of the patients. Using continuous monitoring (e. g. by implantable loop recorders) atrial fibrillation can even be detected in one quarter of the patients. Not all stroke patients can receive such an intensive monitoring. Therefore, this article summarizes the evidence and presents the resulting recommendations for patient selection and staged rhythm diagnostics and discusses a recently presented algorithm of an expert group for use in daily clinical practice.

[Baroreflex activation therapy : Indication and evidence in resistant hypertension and heart failure]. / Barorezeptoraktivierungstherapie : Indikation und Evidenz bei therapieresistenter Hypertonie und Herzinsuffizienz.

Baroreflex activation therapy (BAT) is a sympathoinhibitory procedure for treatment of therapy-resistant hypertension (rsHTN) and severe heart failure with reduced ejection fraction (HFrEF) that been available for several years. The double-blind, randomized Rheos Pivotal Trial demonstrated a blood pressure lowering effect in patients with rsHTN for the first-generation BAT device. A smaller randomized study in heart failure showed that the Barostim Neo system is safe and can improve heart failure symptoms and decrease neuroendocrine activation. However, for this unilateral system, which is currently in clinical use, no data from large randomized trials exist. Despite existing data for BAT in rsHTN and HFrEF, large randomized trials, showing reduction of blood pressure and cardiovascular events are still lacking. Therefore, BAT's efficacy and safety cannot be conclusively assessed.

[Atrial fibrillation as a comorbidity of heart failure]. / Vorhofflimmern als Komorbidität bei Herzinsuffizienz.

Atrial fibrillation and heart failure are diseases that frequently occur together in patients, and the prevalence of the two diseases will continue to increase in the future. Unfortunately, they exacerbate each other: the prognosis of patients with atrial fibrillation is poorer if there is heart failure, and the prognosis of heart failure patients with atrial fibrillation is poorer than the prognosis of heart failure patients without atrial fibrillation. In the past, studies on drug stabilization of sinus rhythm with antiarrhythmic drugs were not able to show any influence on the prognosis of patients. In these patients, it seems to be better to treat the atrial fibrillation interventionally. The CASTLE-AF study has just shown for the first time that isolation of the pulmonary vein to treat atrial fibrillation in heart failure patients has positive effects: hospital admissions for heart failure decreased and the overall survival improved. Further studies have shown that quality of life improves and performance is increased.

[Acute treatment and secondary prophylaxis of ischemic stroke : An excellent example for personalized medicine]. / Akuttherapie und Sekundärprophylaxe des ischämischen Schlaganfalls : Ein Musterbeispiel für personalisierte Medizin.

About a quarter of a million people in Germany suffer a stroke every year. Stroke is the most dreaded cardiovascular disease, even before myocardial infarction and heart failure. In the last two to three years, significant progress has been made in acute treatment, secondary prophylaxis in patients with patent foramen ovale, and the interdisciplinary evaluation of atrial fibrillation as the cause of the stroke. These new findings allow for more precise treatment.

Automatic detection of paroxysmal atrial fibrillation in patients with ischaemic stroke: better than routine diagnostic workup?

BACKGROUND AND PURPOSE: Prolonged electrocardiogram (ECG) monitoring after ischaemic stroke increases the diagnostic yield of paroxysmal atrial fibrillation (pAF). In order to facilitate the additional workload involved in ECG analysis due to prolonged monitoring times, we investigated the effectiveness of pAF detection with an automated software algorithm (SA) in comparison to the routine staff-based analysis (RA) during standard stroke-unit care. Therefore, patients with acute ischaemic stroke or transitory ischaemic attack presenting with sinus rhythmus on the admission ECG and no history of atrial fibrillation were prospectively included. METHODS: A 24-h Holter ECG assessment was performed using either RA based on a computer-aided evaluation and subsequent review by a cardiologist or a commercially available automated SA. In the case of discordant results concerning the occurrence of pAF between the two methods, the data underwent an independent external rating. RESULTS: Of 809 prospectively enrolled patients, 580 patients fulfilled the inclusion criteria. pAF was ultimately diagnosed in 3.3% of the cohort (19 patients). SA and RA correctly diagnosed pAF in 17 patients resulting in a comparable diagnostic effectiveness of the analysis methods (sensitivity: SA 89.5% vs. RA 89.5%; specificity: SA 99.3% vs. RA 99.1%; κ, 0.686; P < 0.001; 95% confidence interval, 0.525-0.847). RA revealed clinically relevant ECG abnormalities in an additional seven patients. CONCLUSIONS: Although it should not completely replace RA, SA-based evaluation of Holter ECG reaches a high diagnostic effectiveness for the detection of pAF and can be used for a rapid and resource-saving analysis of ECG data to deal with prolonged monitoring times.

[Assessment of subjective physical well-being in heart failure : Validation of the FEW16 questionnaire]. / Erfassung des subjektiven körperlichen Wohlbefindens bei Herzinsuffizienz : Validierung des FEW16-Fragebogens.

INTRODUCTION: Improvement in the quality of life (QoL) is a major goal of therapy for heart failure (HF) patients. Physical well-being as an important component of QoL has not yet been sufficiently covered by disease-specific assessment instruments. The aim of the study was to validate the questionnaire for assessing subjective physical well-being (FEW16) in HF patients with preserved ejection fraction (HFpEF) from the exercise training in diastolic heart failure (Ex-DHF­P) trial. METHOD: A total of 64 HFpEF patients (65 years, 56 % female) were randomized to usual routine treatment with (n = 44) or without training (n = 20). At baseline and 3 months, patients were clinically evaluated and assessed using appropriate questionnaires on the QoL (SF36), physical well-being (FEW16) and depression (PHQ-D). RESULTS: The FEW16 showed good values for Cronbachs' alpha coefficients (0.85-0.93). The cross-validity with SF36 and PHQ-D was highly significant but more so for psychological aspects. At baseline, the FEW16 score correlated with age, the subscale resilience with age and the 6 min walking distance test. At follow-up, the total and resilience scores had improved in the training group. In contrast to the SF36, the FEW16 did not detect differences between the groups in Ex-DHF­P. DISCUSSION: The FEW16 questionnaire showed good internal consistency and correlation with SF36, its total score and resilience had improved after training; however, it did not reflect different changes between the study groups. The FEW16 is therefore more suited to assess general/mental well-being than the subjective physical well-being.

[Pulmonary hypertension associated with left heart disease: recommendations of the Cologne Consensus Conference 2016]. / Pulmonale Hypertonie bei Linksherzerkrankungen: Empfehlungen der Kölner Konsensus-Konferenz 2016.

The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension are also valid for Germany. While the guidelines contain detailed recommendations regarding pulmonary arterial hypertension (PAH), they contain only a relatively short paragraph on other, much more common forms of PH such as PH due to left heart disease. Despite the lack of data, targeted PAH treatments are increasingly being used for PH associated with left heart disease. This development is of concern because of limited ressources and the need to base treatments on scientific evidence. On the other hand, PH is a frequent problem that is highly relevant for morbidity and mortality in patients with left heart disease, representing an unmet need of targeted PH therapies. It that sense, the practical implementation of the European Guidelines in Germany requires the consideration of several specific issues and already existing novel data. This requires a detailed commentary to the guidelines, and in some aspects an update already appears necessary. In June 2016, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany. This conference aimed to solve practical and controversial issues surrounding the implementation of the European Guidelines in Germany. To this end, several working groups were initiated, one of which was specifically dedicated to PH associated with left heart disease. This article summarizes the results and recommendations of this working group.

[Invasive treatment of hypertension : Update 2016]. / Interventionelle Hypertonietherapie : Update 2016.

Invasive treatment methods-more specifically renal denervation and baroreceptor activator therapy-have been used for the treatment of therapy-resistant hypertension for several years now. In particular, renal denervation has aroused great interest because it was easy to perform and the first studies provided very promising results. Meanwhile, however, three randomized, blinded studies have been published, and none showed a significant benefit of renal denervation compared to a sham procedure. In addition, in several studies it was demonstrated that intensification of drug therapy, particularly with spironolactone, is at least comparable. Carotid sinus node baroreceptor activator therapy tends to be superior to renal denervation, but the probe currently used is not optimal. The first results by inserting an arteriovenous shunt between the iliac artery and vein are promising, but lack long-term safety data. Currently, all invasive treatment procedures should be performed within the framework of studies or accurate register surveys.

[Interventional strategies in hypertension management]. / Interventionelle Strategien zur Behandlung der Hypertonie.

A number of invasive treatment approaches have become established in the management of severe treatment-resistant hypertension in recent years, including renal denervation and baroreceptor activation therapy. Both methods achieve their antihypertensive effect by influencing the autonomic nervous system. Renal denervation in particular has stimulated considerable interest, since it is simple to perform and initial studies have yielded highly promising results. However, enthusiasm has waned significantly since the initial euphoria. This is due to the fact that the first randomized placebo-controlled double-blind study showed the method to have no significant effect on blood pressure. This experience illustrates the importance of conducting double-blind studies. On the other hand, these results should not lead to renal denervation being shelved. On the contrary, it is worth attempting to improve the treatment and develop criteria to identify which patients it is likely to benefit. Although experience with baroreceptor activation therapy is significantly more limited, similar conclusions can be drawn on it, despite the fact that-in contrast to renal denervation-it achieved a blood pressure reduction of around 10 mmHg in a double-blind study. A potential novel treatment approach lies in creating an arteriovenous shunt between the iliac artery and vein, which has a particularly marked effect on diastolic blood pressure by reducing peripheral resistance. Therapy using brain stimulation of areas in the brainstem region responsible for blood pressure regulation is still at an experimental stage.

Reverse epidemiology in different stages of heart failure.

BACKGROUND: In heart failure (HF), traditional cardiovascular risk factors (RF) as body mass index (BMI), total cholesterol (TC) and systolic blood pressure (SBP) are associated with better survival. It is unknown at which time point along the disease continuum the adverse impact of these RF ceases and may 'start to reverse'. We analyzed the distribution of RF and their association with survival across HF stages. METHODS: We pooled data from four cohort studies from the German Competence Network HF. Employing ACC/AHA-criteria, patients were allocated to stage A (n=218), B (n=1324), C1 (i.e., New York Heart Association [NYHA] classes I & II; n=1134), and C2+D (NYHA III & IV; n=639). RESULTS: With increasing HF severity median age increased (63/67/67/70 years), whereas the proportion of females (56/52/37/35%), median BMI (26.1/28.8/27.7/26.6 kg/m(2)), TC (212/204/191/172 mg/dl), and SBP (140/148/130/120 mmHg) decreased (P<0.001 for trend for all). In the total cohort, higher levels of all RF were associated with better survival, even after extensive adjustment for multiple confounders. If analyses were stratified, however, a higher RF burden predicted better survival only in clinically symptomatic patients: hazard ratio (HR) per +2 kg/m(2) BMI 0.91 (95% confidence interval 0.88; 0.95); per +10 mg/dl TC 0.93 (0.92; 0.95); per +5 mmHg SBP 0.94 (0.92; 0.95). CONCLUSION: In this well-characterized sample of patients representing the entire HF continuum, reverse associations were only consistently observed in symptomatic HF stages. Our data indicate that the phenomenon of a "reverse epidemiology" in HF is subject to significant selection bias in less advanced disease.

[Diastolic heart failure]. / Diastolische Herzinsuffizienz.

BACKGROUND: Heart failure with preserved ejection fraction (i.e. diastolic heart failure) accounts for about half of heart failure cases. The aim of this review is to reflect current knowledge regarding the epidemiology, pathophysiology and treatment. RESULTS: Diastolic heart failure patients are principally elderly and predominantly female. Numerous pathophysiological alterations in this disease have been shown and recent therapeutic recommendations include control of cardiovascular risk factors and symptoms. New therapeutic options, such as inhibition of late sodium current, aldosterone receptor blockade, combined inhibition of AT1 receptor and the enzyme neprilysin, and phosphodiesterase 5 inhibition are discussed in this review and ongoing clinical trials are also briefly presented. CONCLUSION: Diastolic heart failure remains a cardiac disease which is difficult to treat; however, new study results allow a better definition of a population of patients who could benefit from specific therapies.

[Function of oesophagus and gastro-oesophageal reflux in patients with cystic fibrosis]. / Funktion der Speiseröhre und gastroösophagealer Reflux bei Patienten mit zystischer Fibrose.

Gastro-oesophageal reflux (GER) has a special meaning for patients with cystic fibrosis (CF). Twelve voluntary patients with CF up to the age of 25 underwent an oesophageal manometry and a 24-hour impedance-pH monitoring. These patients were without symptoms of GER. The examination proved an acid GER in 42 %. In the total population the frequency is ≤ 10 %. In 11 of 12 patients a pathologically low pressure of the lower oesophageal sphincter (LES) was found. No significant correlations between the DeMeester score and the pressure of the LES, the reflux and respiratory symptomatology, the lung function as well as the quality of life could be proven. However, there was a significant correlation between the DeMeester score and the acid clearance time. 37 % of the registered cough pushes were related to a GER, of which 78 % were associated with an acid GER. Therefore, coughing in patients with CF must not necessarily be caused by the underlying disease. The timely detection of a pathological GER in patients with CF, but without symptoms of GER, and its prompt therapy could protect the lung function.

Clinical predictors to identify paroxysmal atrial fibrillation after ischaemic stroke.

BACKGROUND AND PURPOSE: Detection of paroxysmal atrial fibrillation (pAF) after an ischaemic cerebrovascular event is of imminent interest, because oral anticoagulation as a highly effective secondary preventive treatment is available. Whereas permanent atrial fibrillation (AF) can be detected during routine electrocardiogram (ECG), longer detection duration will detect more pAF but might be resource consuming. The current study tried to identify clinical predictors for pAF detected during long-term Holter ECG and clinical follow-up. METHODS: Patients with acute ischaemic stroke were prospectively investigated with an intensified algorithm to detect pAF (7-day Holter ECG, follow-up investigations after 90 days and 1 year). RESULTS: Two hundred and eighty-one patients were included, 44 of whom had to be excluded since they presented with permanent AF and another 13 patients had to be excluded due to other causes leaving 224 patients (mean age 68.5 years, 58.5% male). Twenty-nine (12.9%) patients could be identified to have pAF during prolonged Holter monitoring, an additional 13 (5.8%) after follow-up investigations. Multivariate analysis identified advanced age [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01-1.08] as well as clinical symptoms >24 h (OR 5.17, 95% CI 1.73-15.48) and a history of coronary artery disease (OR 3.14, 95% CI 1.35-7.28) to be predictive for the detection of pAF. CONCLUSIONS: In acute stroke patients with advanced age, history of coronary artery disease and clinical symptoms >24 h, a prolonged Holter ECG monitoring and follow-up is warranted to identify pAF. This could increase the detection rate of patients requiring anticoagulation and may be able to reduce the risk of recurrent stroke in the case of successful anticoagulation of these patients.

[Recommendations for the treatment of heart failure : What's new?]. / Empfehlung zur Herzinsuffizienz : Was gibt es Neues?

Treatment escalation of chronic systolic heart failure depends on left ventricular function and symptoms of the patients. In symptomatic patients with severely reduced left ventricular function (ejection fraction ≤ 30 %), the following therapeutic approaches are recommended: (1) angiotensin-converting enzyme (ACE) inhibitors (angiotensin receptor blocker in case of ACE inhibitor intolerance); (2) ß-blockers; (3) mineralocorticoid receptor antagonists; (4) diuretics in case of signs and symptoms of congestion; (5) digitalis, in particular in patients with atrial fibrillation; (6) ivabradine in patients with sinus rhythm and a heart rate ≥ 75/min; (7) an implantable cardioverter defibrillator (ICD); (8) in case of left bundle branch block or wide QRS complex, cardiac resynchronization therapy (CRT; in most cases in combination with an implantable cardioverter defibrillator); (9) intravenous administration of iron in case of iron deficiency; (10) exercise training should be strongly recommended in patients with stable heart failure.

[Heart or brain? Problem patients at the interface between cardiology and neurology]. / Herz oder Hirn? Problempatienten an der Schnittstelle zwischen Kardiologie und Neurologie.

A large number of patients fall into a category at the interface between heart or brain and are expected to require thorough clinical knowledge from both the cardiological as well as the neurological point of view for further patient-oriented treatment. The current article therefore addresses this important issue and aims to provide important information for clinical decision making for those patients at the interface between heart and brain. Due to the clinical impact, patients with carotid stenosis, a patent foramen ovale or non-valvular atrial fibrillation are described in more detail in this article.

Making health care safer II: an updated critical analysis of the evidence for patient safety practices.

OBJECTIVES: To review important patient safety practices for evidence of effectiveness, implementation, and adoption. DATA SOURCES: Searches of multiple computerized databases, gray literature, and the judgments of a 20-member panel of patient safety stakeholders. REVIEW METHODS: The judgments of the stakeholders were used to prioritize patient safety practices for review, and to select which practices received in-depth reviews and which received brief reviews. In-depth reviews consisted of a formal literature search, usually of multiple databases, and included gray literature, where applicable. In-depth reviews assessed practices on the following domains: • How important is the problem? • What is the patient safety practice? • Why should this practice work? • What are the beneficial effects of the practice? • What are the harms of the practice? • How has the practice been implemented, and in what contexts? • Are there any data about costs? • Are there data about the effect of context on effectiveness? We assessed individual studies for risk of bias using tools appropriate to specific study designs. We assessed the strength of evidence of effectiveness using a system developed for this project. Brief reviews had focused literature searches for focused questions. All practices were then summarized on the following domains: scope of the problem, strength of evidence for effectiveness, evidence on potential for harmful unintended consequences, estimate of costs, how much is known about implementation and how difficult the practice is to implement. Stakeholder judgment was then used to identify practices that were "strongly encouraged" for adoption, and those practices that were "encouraged" for adoption. RESULTS: From an initial list of over 100 patient safety practices, the stakeholders identified 41 practices as a priority for this review: 18 in-depth reviews and 23 brief reviews. Of these, 20 practices had their strength of evidence of effectiveness rated as at least "moderate," and 25 practices had at least "moderate" evidence of how to implement them. Ten practices were classified by the stakeholders as having sufficient evidence of effectiveness and implementation and should be "strongly encouraged" for adoption, and an additional 12 practices were classified as those that should be "encouraged" for adoption. CONCLUSIONS: The evidence supporting the effectiveness of many patient safety practices has improved substantially over the past decade. Evidence about implementation and context has also improved, but continues to lag behind evidence of effectiveness. Twenty-two patient safety practices are sufficiently well understood, and health care providers can consider adopting them now.
