Background

We have a limited understanding of the biological underpinnings of symptoms in heart failure (HF).

Objectives

The purpose of this paper was to compare relationships between peripheral biomarkers of HF pathogenesis and physical symptoms between patients with advanced versus moderate HF.

Methods

This was a two-stage phenotype sampling cohort study wherein we examined patients with advanced HF undergoing ventricular assist device implantation in the first stage, and then patients with moderate HF (matched adults with HF not requiring device implantation) in the second stage. Linear modeling was used to compare relationships among biomarkers and physical symptoms between cohorts.

Results

Worse myocardial stress, systemic inflammation and endothelial dysfunction were associated with worse physical symptoms in moderate HF (n=48), but less physical symptom burden in advanced HF (n=48).

Conclusions

Where patients are in the HF trajectory needs to be taken into consideration when exploring biological underpinnings of physical HF symptoms.  相似文献

Background

In our prior study of 250 outpatient veterans with heart failure (HF), 58% had unrecognized cognitive impairment (CI) which was linked to worsened medication adherence. Literature suggests HF patients with CI have poorer clinical outcomes including higher mortality.

Objective

The study is to examine mortality rates in outpatients with HF and undiagnosed CI compared to their cognitively intact peers.

Methods

This is a retrospective study for all-cause mortality.

Results

During the 3-year follow up, 64/250 (25.6%) patients died: 20/106 (18.9%) with no CI, 29/104 (27.9%) with mild CI, and 15/40 (37.5%) with severe CI. Patients with CI were at increased risk for mortality (hazard ratio 1.82, p?=?0.038). Those with severe CI had the worst outcome (hazard ratio 2.710, p?=?0.011).

Conclusions

CI was an independent risk factor for mortality in patients with heart failure when controlling for age and markers of disease severity. Cognitive screening should be performed routinely to identify patients at greater risk for adverse outcomes.  相似文献

Background

The present study performed a meta-analysis of randomized and prospective trials to compare the outcomes of percutaneous coronary intervention (PCI) with stents versus coronary artery bypass graft surgery (CABG) for unprotected left main coronary artery (UPLM) stenosis.

Methods

The Cochrane Library, PubMed and EMBASE databases were systematically searched until July 2017. The Newcastle-Ottawa scale was used for quality assessment.

Results

A total of 19 studies with 16,900 participants were included. Pooled analysis showed no significant differences in all-cause mortality (odds ratio [OR] 0.94; 95% CI 0.74-1.20) and cardiac death (OR 1.04; 95% CI 0.74-1.47). However, subgroup analysis showed that PCI was associated with a low all-cause mortality rate at 30-day follow up (OR 0.48; 95% CI 0.26-0.89). The stroke rate in PCI was lower in short-term follow up (OR 0.45; 95% CI 0.23-0.88) and long-term follow up (OR 0.36; 95% CI 0.27-0.47). On the other hand, PCI was associated with higher risk of myocardial infarction (OR 1.59; 95% CI 1.34-1.88), repeat revascularization (OR 2.47; 95% CI 1.80-3.37) and target vessel revascularization (OR 2.10; 95% CI 1.72-2.57) compared to CABG in the pooled analysis.

Conclusions

The current evidence suggests that the risk of stroke was significantly reduced in PCI compared to that in CABG. Therefore, PCI is the preferred treatment for patients with a high risk of stroke. Additionally, in short-term follow up, PCI was reported to be safe and effective for UPLM patients compared to CABG. However, CABG caused fewer complications long term.  相似文献

Background

Endoscopic biliary decompression using bilateral self-expandable metallic stent (SEMS) placed using the stent-in-stent (SIS) technique is considered favorable for unresectable malignant hilar biliary obstruction (MHBO). However, occlusion of the bilateral SIS placement is frequent and revision can be challenging. This study was performed to investigate the efficacy, the long-term patency and the appropriate approach for revision of occluded bilateral SIS placement in unresectable MHBO.

Methods

From January 2011 to July 2016, thirty-eight patients with unresectable MHBO underwent revision of occluded bilateral SIS placement. Clinical data including success rates and patency of revision, were retrospectively analyzed.

Results

The technical success rate of revision was 76.3%. The clinical success rate of revision was 51.7% and mean patency of revision was 49.1 days. No significant predictive factor for clinical failure of revision was observed. The cell size of SEMS was not found to have significant effects on clinical success rates or revision patency.

Conclusions

Revision of occluded bilateral SIS placement for MHBO showed fair patency and clinical success rate. Revision method and cell size of SEMS were not found to influence clinical outcomes.  相似文献

Introduction

Practice guidelines recommend that patients with peripheral artery disease receive antiplatelets, statins, and angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). We sought to quantify the rates of prescribing these therapies in patients with peripheral artery disease in the literature.

Methods

We performed a systematic review and meta-analysis of treatment prescribing rates in observational studies containing peripheral artery disease patients published on or after the year 2000. We also assessed whether prescribing rates are increasing over time.

Results

A total of 86 studies were available for analysis. The aggregate sample size across all studies was 332,555. The pooled estimates for utilization of antiplatelets, statins, and ACE inhibitors or ARBs were 75% (95% confidence interval [CI], 71%-79%), 56% (95% CI, 52%-60%), and 53% (95% CI, 49%-58%), respectively. Statin use was directly related to publication year (+2.0% per year, P < .001), but this was not the case for antiplatelets (P?=?.68) or ACE inhibitors or ARBs (P?=?.066).

Conclusions

Although some improvement in statin prescribing has occurred in recent years, major practice gaps exist in the treatment of peripheral artery disease. Effective measures to close these gaps should be implemented.  相似文献

Purpose

This study aimed to determine changes in absolute and relative socioeconomic inequalities in hospital admissions for major cardiovascular causes among patients with diabetes in England.

Methods

We identified all patients with diabetes aged ≥45 years admitted to the hospital in England between 2004-2005 and 2014-2015 for acute myocardial infarction, stroke, percutaneous coronary intervention, or coronary artery bypass graft. We measured socioeconomic status using the Index of Multiple Deprivation. Diabetes-specific admission rates were calculated for each year by deprivation quintile. We assessed temporal changes using negative binomial regression models.

Results

Most admissions occurred among patients aged ≥65 years (71%) and men (63.3%). The number of admissions increased steadily from the least quintile to the most deprived quintile. Patients in the most deprived quintile had a 1.94-fold increased risk of acute myocardial infarction (95% confidence interval [CI], 1.79-2.10), 1.92-fold increased risk of stroke (95% CI, 1.78-2.07), 1.66-fold increased risk of coronary artery bypass graft (95% CI, 1.50-1.74), and 1.76-fold increased risk of percutaneous coronary intervention (95% CI, 1.64-1.89) compared with the least deprived group. Absolute differences in rates between the least and most deprived quintiles did not change significantly for acute myocardial infarction (P?=?.29) and were reduced for stroke, coronary artery bypass graft, and percutaneous coronary intervention (by 17.5, 15, and 11.8 per 100,000 patients with diabetes, respectively, P ≤ .01 for all).

Conclusions

Socioeconomic inequalities persist in diabetes-related hospital admissions for major cardiovascular events in England. Besides improved risk stratification strategies that consider socioeconomically defined needs, wide-reaching population-based policy interventions are required to reduce inequalities in diabetes outcomes.  相似文献

Background: Low resectability and poor survival outcome are common for hilar cholangiocarcinoma(HCCA), especially in advanced stages. The present study was to assess the clinical outcome of advanced HCCA, focusing on therapeutic modalities, survival analysis and prognostic assessment.Methods: Clinical data of 176 advanced HCCA patients who had been treated in our hospital between January 2013 and December 2015 were analyzed retrospectively. Prognostic effects of clinicopathological factors were explored by univariate and multivariate analysis. Survival predictors were evaluated by the receiver operating characteristic(ROC) curve.Results: The 3-year overall survival rate was 13% for patients with advanced HCCA. Preoperative total bilirubin(P = 0.009), hepatic artery invasion(P = 0.014) and treatment modalities(P = 0.020) were independent prognostic factors on overall survival. A model combining these independent prognostic factors(area under ROC curve: 0.748; 95% CI: 0.678–0.811; sensitivity: 82.3%, specificity: 53.5%) was highly predictive of tumor death. After R0 resection, the 3-year overall survival was up to 38%. Preoperative total bilirubin was still an independent negative factor, but not for hepatic artery invasion.Conclusions: Surgery is still the best treatment for advanced HCCA. Preoperative biliary drainage should be performed in highly-jaundiced patients to improve survival. Prediction of survival is improved significantly by a model that incorporates preoperative total bilirubin, hepatic artery invasion and treatment modalities.  相似文献

Background

Advances in cardiorespiratory monitoring have made the extracorporeal membrane oxygenation (ECMO) technique safer for the patient. Noninvasive, continuous tools are available, although data on their applications in the neonatal ECMO setting are lacking.

Objective

We retrospectively described the neonatal clinical application of this continuous, noninvasive ECMO monitor and compared the analyzed parameters from those derived from blood gas analysis.

Materials and methods

We performed 897 h of cardiorespiratory monitoring during neonatal venoarterial-ECMO (VA-ECMO) for four patients affected by (cardio-) respiratory failure, to compare the reliability of a noninvasive, continuous monitoring Spectrum M4® (M4) (Spectrum Medical, Gloucester, England) to an invasive, intermittent co-monitoring with blood gas analyzer (Radiometer Medical ApS, Brønshøj, Denmark).

Results

A range of 117 pairs (time-matched BGA-derived vs. M4-derived parameters) was retrospectively analyzed. T-test, linear regression and Bland–Altman analysis for hemoglobin, hematocrit, venous oxygen saturation, oxygen delivery, oxygen consumption, oxygen extraction ratio, oxygen partial pressure, and carbon dioxide partial pressure showed a strong relationship between the two monitors for all parameters analyzed (p < 0.0001).

Conclusions

Continuous, noninvasive cardiorespiratory monitoring appears to be feasible and reliable, although its accuracy needs to be verified in a more extensive cohort.  相似文献

Background

Efficient ampullary intervention is essential for endoscopic retrograde cholangiopancreatography (ERCP) in patients with a prior Billroth II gastrectomy. We retrospectively evaluated the safety and effectiveness of ampullary intervention using fully covered self-expandable metal stents (FCSEMSs) for the management of common bile duct (CBD) stones in a subset of patients with a history of Billroth II gastrectomy.

Methods

This retrospective analysis involved patients with a prior Billroth II gastrectomy who underwent ampullary intervention with FCSEMSs for the management of CBD stones. The factors associated with FCSEMSs placement, treatment success, and procedural complications were analyzed.

Results

A group of 15 patients (10 males; median age, 78 years) underwent biliary metal stent placement for high degree of CBD angulation (6), small or flat papilla with unclear margin (5), current use of double antiplatelet agents or an anticoagulant (2), unwanted instrumentation of the cystic duct (1), and insecure position of the scope (1). Ampullary intervention with FCSEMSs was successful in all patients. After dilating the ampulla of Vater and building a durable conduit with FCSEMSs immediately, CBD stones were removed successfully from all patients in a single session. A mild post-ERCP pancreatitis occurred in one patient, who recovered without complications.

Conclusion

Ampullary intervention with FCSEMSs is safe and effective for the management of CBD stones in a subset of patients with a history of Billroth II gastrectomy.  相似文献

Background

Laparoscopic anatomic hepatectomy remains challenging because of the complex interior structures of the liver. Our novel strategy includes the Glissonian approach and the major hepatic vein first, which serves to define the external and internal landmarks for laparoscopic anatomic hepatectomy.

Methods

Eleven cases underwent laparoscopic anatomic hepatectomy, including three right hepatectomies, three left hepatectomies, three right posterior hepatectomies, and two mesohepatectomies. The Glissonian approach was used to transect the hepatic pedicles as external demarcation. The major hepatic vein near the hepatic portal was exposed and served as the internal landmark for parenchymal transection. The liver parenchyma below and above the major hepatic vein was transected along the major hepatic vein. Fifty-nine subjects were used to compare the distance between the major hepatic vein and secondary Glisson pedicles among different liver diseases.

Results

The average operative time was 327 min with an estimated blood loss of 554.55 mL. Only two patients received three units of packed red blood cells. The others recovered normally and were discharged on postoperative day 7. The distance between right posterior Glissonian pedicle and right hepatic vein was shorter in the patients with cirrhosis than that without cirrhosis, and this distance was even shorter in patients with hepatocellular carcinoma.

Conclusion

The Glissonian approach with the major hepatic vein first is easy and feasible for laparoscopic anatomic hepatectomy, especially in patients with hepatocellular carcinoma and cirrhosis.  相似文献

Background

Little has been reported about protocol-driven outpatient palliative care consultation (OPCC) for advanced heart failure (HF).

Objectives

To describe evaluation practices and treatment recommendations made during protocol-driven OPCCs for advanced HF.

Methods

We performed content analysis of OPCCs completed as part of ENABLE CHF-PC, an early palliative care HF intervention, conducted at sites in the Northeast and Southeast. T-tests, Fisher's exact, and Chi-square tests were used to evaluate sociodemographic, outcome measures, and site content differences.

Results

Of 61 ENABLE CHF-PC participants, 39 (64%) had an OPCC (Northeast, n=27; Southeast, n=12). Social and medical history assessed most were close relationships (n=35, 90%), family support (n=33, 85%), advance directive status (n=33, 85%), functional status (n=30, 77%); and symptoms were mood (n= 35, 90%), breathlessness (n=28, 72%), and chest pain (n=24, 62%). Treatment recommendations focused on care coordination (n=13, 33%) and specialty referrals (n=12, 31%). Between-site OPCC differences included assessment of family support (Northeast vs. Southeast: 100% vs. 50%), code status (96% vs. 58%), goals of care discussions (89% vs. 41.7%), and prognosis understanding (85% vs. 33%).

Conclusion

OPCCs for HF focused on evaluating medical and social history, along with goals of care and code status discussions. Symptom evaluation commonly included mood disorders, pain, dyspnea, and fatigue. Notable regional differences were found in topics evaluated and OPCC completion rates.  相似文献

Background: Previous studies have emphasized the need to reduce tacrolimus(TAC) trough levels in the early post-liver transplantation(LT) period. However, whether late-period TAC trough levels influence the long-term outcomes of liver recipients is not clear.Methods: We enrolled 155 adult liver recipients survived more than 3 years after living donor liver transplantation because of non-malignant liver diseases. The maintenance immunosuppressive regimens were TAC monotherapy and combined therapy with mycophenolate mofetil. Patients were divided into three groups according to their late-period TAC trough levels: 3 ng/m L group, 3–5 ng/m L group, and5 ng/m L group. The complications and adverse effects of TAC were analyzed.Results: Each group showed similar rejection, graft loss and mortality. Patients achieved the 5 ng/m L state in less than 4 years had fewer new-onset diabetes, hyperlipidemia, de novo malignancies, and hepatitis B virus recurrence; the complications of renal dysfunction and hypertension rates were the same among these 3 groups.Conclusions: Collectively, our findings indicated that lower TAC trough levels in the late period of liver transplantation are safe, improve the long-term outcomes.  相似文献

Background

Accumulating evidence demonstrates that microRNAs (miRNAs) play essential roles in tumorigenesis and cancer progression of hepatocellular carcinoma (HCC). Average targets of a miRNA were more than 100. And one miRNA may act in tumor via regulating several targets. The present study aimed to explore more potential targets of miR-449a by proteomics technology and further uncover the role of miR-449a in HCC tumorigenesis.

Methods

Technologies such as iTRAQ-based quantitative proteomic were used to investigate the effect of miR-449a on HCC. The expression of c-Met and miR-449a was detected by qRT-PCR in HCC samples. Gain- and loss-of-function experiments were performed to identify the function and potential target of miR-449a in HCC cells.

Results

In HCC, miR-449a was significantly downregulated, while c-Met was upregulated concurrently. Quantitative proteomics and luciferase reporter assay identified c-Met as a direct target of miR-449a. Moreover, miR-449a inhibited HCC growth not only by targeting CDK6 but also by suppressing c-Met/Ras/Raf/ERK signaling pathway. Furthermore, the inhibition of c-Met expression with a specific siRNA significantly inhibited cells growth and deregulated the ERK pathway in HCC.

Conclusion

The tumor suppressor miR-449a suppresses HCC tumorigenesis by repressing the c-Met/ERK pathway.  相似文献

Background

The 2016 U.S. Preventive Services Task Force (USPSTF) guidelines for primary prevention statin therapy are more restrictive than the 2013 American College of Cardiology/American Heart Association (ACC/AHA) guidelines. There are important differences in how application of the risk thresholds from these guidelines would impact particular segments of the U.S. population.

Methods

Data from the National Health and Nutrition Examination Survey (2005-14) were used to determine statin eligibility across age, gender, and racial or ethnic group using criteria from the 2013 ACC/AHA and 2016 USPSTF guidelines. Proportions of the study population eligible for statins under the ACC/AHA 5% and 7.5% risk thresholds were compared with those eligible under the 2016 USPSTF 10% guidelines.

Results

Of the 5388 study participants, 34% were eligible for statin therapy under the USPSTF guideline compared with 43% under the Class I (7.5%) ACC/AHA treatment threshold and 53% under the Class IIa (5%) ACC/AHA treatment threshold. Moving from the USPSTF 10% threshold to the ACC/AHA 5% threshold increased statin eligibility for males ages 40-59 from 26%-48% (whites), from 19%-43% (Hispanics), and from 33%-74% (blacks). A similar disproportionate but less pronounced effect was seen when different risk thresholds were used for statin eligibility among women ages 40-59 across differing races and ethnicities.

Conclusions

In this sample of U.S. adults from the National Health and Nutrition Examination Survey database, full implementation of the higher USPSTF statin treatment threshold could lead to less overall statin use and disproportionately lower statin use among non-Hispanic blacks.  相似文献

Background: In general, para-aortic lymph node(LN16) metastasis has been considered as a contraindication for pancreatic resection. However, some pancreatic cancer patients with LN16 metastasis have been reported to survive for longer than expected after pancreatectomy. The purpose of this study was to determine whether pancreatic cancer patients with LN16 metastasis might benefit from surgery.Methods: We retrospectively reviewed 201 consecutive patients with invasive pancreatic ductal adenocarcinoma who underwent surgery at Osaka National Hospital between April 2003 and December 2012.These patients included 22 patients with LN16 metastasis who underwent an extended lymphadenectomy and 25 patients who underwent a palliative surgical biliary and gastric bypass. The clinicopathological data and outcomes were evaluated using univariate and multivariate analyses.Results: The overall survival of the patients with LN16 metastasis was poorer than that of the LN16-negative patients(P = 0.0014). An overall survival analysis of the LN16-positive patients stratified according to the preoperative CA19-9 level showed a significant difference between patients with a low preoperative CA19-9 level(≤360 U/mL) and those with a high preoperative CA19-9 level(360 U/mL)(P = 0.0301). No significant difference in overall survival of patients was observed between those with LN16 positivity and those who underwent bypass surgery. However, the overall survival of the LN16-positive patients with a CA19-9 level ≤360 U/mL(n = 11) was significantly higher than that of those who underwent bypass surgery(P = 0.0452).Conclusion: Surgical resection and extended lymphadenectomy remains an option for pancreatic cancer patients with LN16-positivity whose CA19-9 level is ≤360 U/mL.  相似文献

Background

Cerebral vasculitis caused by neurosyphilis is a re-emerging problem with diagnostic and treatment issues, especially for human immunodeficiency virus patients.

Methods

We present a case of relapsing syphilis-associated cerebral vasculitis, despite the recommended first-line antibiotic treatment, that was successfully treated with a second intravenous penicillin G course and corticosteroids.

Results

A 50-year old man went to the emergency department for bilateral episodes of red and painful eyes with progressive but severe visual acuity loss. He was diagnosed with bilateral panuveitis and neurosyphilis favored by an unknown human immunodeficiency virus infection with a CD4 count of 236 mm3. Despite appropriate and well-conducted treatment including intravenous penicillin G, short-term corticosteroid, and highly active antiretroviral therapy, a symptomatic relapse of the syphilis-associated cerebral vasculitis occurred. After a second course of penicillin and corticosteroids, he made a complete recovery.

Conclusions

Neurosyphilis and human immunodeficiency virus co-infection is a reappearing challenging situation that should be considered with care by physicians because recommended antibiotic treatment sometimes fails. Corticosteroid therapy should be discussed in case of cerebral vasculitis.  相似文献

Background: Autoimmune liver diseases(ALDs) consist of autoimmune hepatitis(AIH), primary biliary cirrhosis(PBC), primary sclerosing cholangitis(PSC), Ig G4-associated cholangitis and overlap syndromes.Patients with these diseases may gradually progress to end-stage liver diseases and need liver transplantation. The present study aimed to explore the prognosis of patients with ALDs after liver transplantation.Methods: The clinical data of 80 patients with ALD(24 cases of AIH, 35 of PBC, 15 of PSC and 6 of AIHPBC overlap syndromes) who underwent liver transplantation in Renji Hospital, Shanghai Jiao Tong University School of Medicine from June 2004 to September 2016 were collected retrospectively. The causes of death were analyzed and the postoperative cumulative survival rate was estimated by the Kaplan–Meier method. Recurrence and other complications were also analyzed.Results: Of the 80 patients, 18 were males and 62 were females. The average age was 50.5 years and the average Model for End-stage Liver Disease(MELD) score was 14.1. After a median follow-up of 19.8 months, 8 patients died. The 1-, 3-and 5-year cumulative survival rates were all 89.0%. Three cases of recurrent ALDs were diagnosed(3.8%) but they were not totally consistent with primary diseases. Biliary tract complication occurred in 10 patients(12.5%). The new onset of tumor was observed in 1 patient(1.3%). De novo HBV/CMV/EBV infection was found in 3, 8 and 3 patients, respectively.Conclusion: Liver transplantation is an effective and safe treatment for end-stage ALD.  相似文献

Background

Studies indicate that decision making and informed consent among patients considering left ventricular assist device (LVAD) support for advanced heart failure could be improved. In the VADDA (Ventricular Assist Device Decision Aid) trial, we tested a patient-centered decision aid (DA) to enhance the quality of decision making about LVAD therapy.

Methods

After an extensive user-centered design process, we conducted a multisite randomized trial of the DA compared with standard education (SE) among inpatients considering LVAD treatment for advanced heart failure The main outcome was LVAD knowledge at 1 week and 1 month after administration of the DA versus the SE, according to a validated scale. Secondary measures included prespecified quality decision making measures recommended by the International Patient Decision Aid Standards collaboration.

Results

Of 105 eligible patients, 98 consented and were randomly assigned to the DA and SE arms. Patients receiving the VADDA exhibited significantly greater LVAD knowledge than the SE group at 1 week of follow-up (P?=?.01) but not at 1 month (P?=?.47). No differences were found between DA and SE patients in rates of acceptance versus decline of LVAD treatment (85% vs 78%; P?=?.74). Recipients in the DA arm reported greater satisfaction with life after implantation compared with nonrecipients (28 vs 23 out of 30; P?=?.008), although both arms reported high satisfaction. Patients rated the DA high in acceptability and usability.

Conclusions

The VADDA enhances LVAD knowledge, particularly in the short term (1 week) during the peak period of decision making. The DA does not encourage decision direction and reflects patient, caregiver, and physician preferences for content and format.

Background: Little information is available about the relationship between restoration of common bile duct(CBD) diameter after endoscopic stone retraction and recurrence of CBD stones in elderly patients.The present study was to determine whether restoration of CBD diameter is a preventive factor for CBD stone recurrence in elderly patients who underwent endoscopic retrograde cholangiopancreatography(ERCP).Methods: From January 2006 to December 2010, 238 patients underwent the first and the second session of ERCP for the removal of CBD stones. Among them, 173 were over 65 years old. These patients were divided into recurrent group and non-recurrent group. Restoration of CBD diameter and patients' characteristics were compared.Results: There was no statistical difference in patients' characteristics, associated diseases, or ERCP-related complications between the two groups. Reduction of CBD diameter was significantly larger in the nonrecurrent group(2.7 ± 1.7 mm) compared to that in the recurrent group(1.4 ± 2.3 mm, P = 0.002). The proportion of patients with restoration of CBD diameter were significantly lower in the recurrent group(6/42, 14.3%) compared with that in the non-recurrent group(67/131, 51.1%)(P 0.01).Conclusions: There is an inverse relationship between restoration of CBD diameter and CBD stone recurrence. Therefore, patients without restoration of CBD diameter within 2 weeks after endoscopic stone removal should be monitored more frequently.  相似文献

Purpose

The red blood cell (RBC) folate test is a laboratory test with limited clinical utility. Previous attempts to reduce physician ordering of unnecessary laboratory tests, including folate levels, have resulted in only modest success. The objective of this study was to assess the effectiveness and impacts of restricting RBC folate ordering in the electronic health record (EHR).

Methods

This was a retrospective observational study that took place from January 2010 to December 2016 at a large academic healthcare network in Toronto, Canada. All inpatients and outpatients who underwent at least 1 RBC folate or vitamin B12 test during the study period were included. Ordering an RBC folate test was restricted to clinicians in gastroenterology and hematology. The option to order the test was removed from other physicians’ computerized order entry screens in the EHR in June 2013.

Results

RBC folate testing decreased by 94.4% during the study, from a mean of 493.0 ± 48.0 tests per month prior to intervention to 27.6 ± 10.3 tests per month after intervention (P < .001).

Conclusions

Restricting RBC folate ordering in the EHR resulted in a large and sustained reduction in RBC folate testing. Significant cost savings, estimated at more than a quarter of a million Canadian dollars over 3 years, were achieved. There was no significant clinical impact of the intervention on the diagnosis of folate deficiency.  相似文献
