Choline Halide-Based Deep Eutectic Solvents as Biocompatible Catalysts for the Alternating Copolymerization of Epoxides and Cyclic Anhydrides.

Aliphatic polyesters have received considerable attention in recent years due to their biodegradability and biocompatible, mechanical, and thermal properties that can make them a suitable alternative to today's commercialized polymers. The ring-opening copolymerization (ROCOP) of epoxides and cyclic anhydrides is a route to synthesize a diverse array of polyesters that could be useful in many applications. However, the catalysts used rarely consider biocompatible catalysts in the case that any are left in the polymer. To the best of our knowledge, we report the first example of using deep eutectic solvents (DESs) as biocompatible catalysts for this target ROCOP with polymerization activity for at least six diverse monomer pairs. Choline halide salts are active for this polymerization, with dried salts showing polymerization slower than that of those conducted in air. Hydrogen bonding with water is hypothesized to enhance the rate-determining step of epoxide ring opening. While the presence of water improves the rate of polymerization, it also acts as a chain transfer agent, leading to smaller molar mass polymers than intended. Combining the choline halide salts with urea or ethylene glycol hydrogen bond donors in air led to DES catalysts that reacted similarly to the salts exposed to air. However, when generating these DESs in air-free conditions, they showed similar rates of polymerization without a drop in polymer molar mass. The hydrogen bonding provided by urea and ethylene glycol seems to promote the rate increase without serving as a chain transfer agent. Results reported herein display the promising potential of biocompatible catalyst systems for this ROCOP process as well as introducing the use of hydrogen bonding to enhance polymerization rates.

Optimizing Post-Acute Coronary Syndrome Dyslipidemia Management: Insights from the North American Acute Coronary Syndrome Reflective III.

INTRODUCTION: Despite contemporary practice guidelines, a substantial number of post-acute coronary syndrome (ACS) patients fail to achieve guideline-recommended LDL-C thresholds. Our study aimed to investigate this guideline recommendations-to-practice care gap. Specifically, we aimed to identify opportunities where additional lipid-lowering therapies are indicated and explore reasons for the non-prescription of guideline-recommended therapies. METHODS: ACS patients with LDL-C ≥1.81 mmol/L (70 mg/dL) despite maximally tolerated statin ± ezetimibe therapy (including those intolerant of ≥2 statins) were enrolled 1-12 months post-event from 27 Canadian and US sites from September 2018 to October 2020 and followed up for three visits during the 12 months post-event. We determined the proportion of patients who did not achieve Canadian/US guideline-recommended LDL-C thresholds, the number of patients who would have been eligible for additional lipid-lowering therapies, and reasons behind lack of escalation in lipid-lowering therapies when indicated. Individual patient and aggregate practice feedback, including guideline-recommended intensification suggestions, were provided to each physician. RESULTS: Of the 248 patients enrolled in the pilot study (median age 64 [57, 73] years, 31.5% female and STEMI 27.4%), 75.4% were on high-intensity statins on the first visit. A total of 18.5% of those who attended all 3 visits had an LDL-C measured only at the first visit which was above the threshold. After 1 year of follow-up, 51.9% of patients achieved LDL-C thresholds at either visit 2 or 3. In the context of feedback reminding physicians about guideline-directed LDL-C-modifying therapy in their individual participating patients, we observed an increase in the use of ezetimibe and PCSK9 inhibitor therapy at 3-12 months. This was associated with a significant lowering of the mean LDL-C (from 2.93 mmol/L [baseline] to 2.09 mmol/L [3-6 months] to 1.87 mmol/L [6-12 months]) and a significantly greater proportion of patients (from 0% [baseline] to 38.6% [3-6 months] to 53.4% [6-12 months]) achieving guideline-recommended LDL-C thresholds. The most prevalent reasons behind the non-intensification of LDL-C-lowering therapy with ezetimibe and/or PCSK9i were LDL-C levels being close to target, the pre-existing use of other lipid-lowering therapies, patient refusal, and cost. CONCLUSION: Although most patients post-ACS were on high-intensity statin therapy, almost 50% failed to achieve guideline-recommended LDL-C thresholds by 1-year follow-up. Furthermore, additional lipid-lowering therapies in this high-risk group were underprescribed, and this might be linked to several factors including potential gaps in physician knowledge, treatment inertia, patient refusal, and cost.

Evaluation of a graduate nurse residency program: A retrospective longitudinal study.

BACKGROUND: There is an urgency to retain nurses globally. Evidence has shown that nurse residency programs promote retention of new graduate nurses. However, there is a dearth of studies examining the impact of nurse residency programs longitudinally. AIM: To evaluate the impact of a transition-to-practice program on new graduate nurses' practice confidence and job satisfaction over 24 months. DESIGN: A retrospective longitudinal study. SETTING: A 1200-bed public tertiary academic hospital. PARTICIPANTS: New graduate nurses from local universities who joined the hospital and were enrolled in the Graduate Nurse Residency Program (n = 104). METHODS: The program was conducted for 24 months and consisted of modules on bedside knowledge and skills, and a mentorship program with senior nurse leaders. Practice confidence and job satisfaction were measured using the Casey-Fink graduate nurse experience survey. The survey was administered four times over the 24 months as part of the program. Data was analyzed using repeated measures ANOVA. RESULTS: Practice confidence increased and job satisfaction decreased over the 24 months. Practice confidence total score at 6 months and an extended probation period were factors associated with attrition during the 24-month clinical practice. CONCLUSIONS: This is the first longitudinal study to demonstrate the impact of a transition-to-practice program in a multiethnic Asian setting. The Graduate Nurse Residency Program enhanced the practice confidence of new graduate nurses.

Antithrombotic therapies in Canadian atrial fibrillation patients with concomitant coronary artery disease: Insights from the CONNECT AF + PCI-II program.

BACKGROUND: Selecting the appropriate antithrombotic regimen for patients with atrial fibrillation (AF) who have undergone percutaneous coronary intervention (PCI) or have had medically managed acute coronary syndrome (ACS) remains complex. This multi-centre observational study evaluated patterns of antithrombotic therapies utilized among Canadian patients with AF post-PCI or ACS. METHODS AND RESULTS: By retrospective chart audit, 611 non-valvular AF patients [median (interquartile range) age 76 (69-83) years, CHADS2 score 2 (1-3)] who underwent PCI or had medically managed ACS between August 2018 and December 2020 were identified by 68 cardiologists across eight provinces in Canada. Overall, triple antithrombotic therapy [TAT: combined oral anticoagulation (OAC) and dual antiplatelet therapy (DAPT)] was the most common initial antithrombotic strategy, with use in 53.8 % of patients, followed by dual pathway therapy (32.7 % received OAC and a P2Y12 inhibitor, and 4.1 % received OAC and aspirin) and DAPT (9.3 %). Median duration of TAT was 30 (7, 30) days. Compared to the previous CONNECT AF + PCI-I program, there was an increased use of dual pathway therapy relative to TAT over time (P-value <.0001). DOACs (direct oral anticoagulants) represented 90.3 % of all OACs used overall, with apixaban being the most utilized (50.5 %). Proton pump inhibitors were used in 57.0 % of all patients, and 70.1 % of patients on ASA. Planned antithrombotic therapies at 1 year were: 76.2 % OAC monotherapy, 8.3 % OAC + ASA, 7.9 % OAC + P2Y12 inhibitor, 4.3 % DAPT, 1.3 % ASA alone, and <1 % triple therapy. CONCLUSION: In accordance with recent Canadian Cardiovascular Society guideline recommendations, we observed an increased use of dual pathway therapy relative to TAT over time in both AF patients post-PCI (elective and emergent) and in those with medically managed ACS. Additionally, DOACs have become the prevailing form of anticoagulation across all antithrombotic regimens. Our findings suggest that Canadian physicians are integrating evidence-based approaches to optimally manage the bleeding and thrombotic risks of AF patients post-PCI and/or ACS.

Validation of a smartphone-based screening tool (Biliscan) for neonatal jaundice in a multi-ethnic neonatal population.

AIM: Neonatal jaundice is an important and prevalent condition that can cause kernicterus and mortality. This study validated a smartphone-based screening application (Biliscan) in detecting neonatal jaundice. METHODS: A cross-sectional prospective study was conducted at the neonatal unit in a tertiary teaching hospital between August 2020 and October 2021. All babies born at the gestation of 35 weeks and above with clinical jaundice or are recommended for screening of jaundice within 21 days of post-natal age were recruited. Using Biliscan, images of the babies' skin over the sternum were taken against a standard colour card. The application uses feature extraction and machine learning regression to estimate the bilirubin level. Independent Biliscan bilirubin estimates (BsB) were made and compared with total serum bilirubin (TSB) and transcutaneous bilirubin (TcB) levels. Bland Altman plots were used to establish the agreement between BsB and TSB, as well as TcB, using the clinically acceptable limits of agreement of ±35 µmol/L, which were defined a priori. Pearson correlation coefficient was assessed to establish the strength of the relationship between BsB versus TSB and TcB. Diagnostic accuracy was assessed through receiver operating characteristic curve analysis. RESULTS: Sixty-one paired TSB-BsB and 85 paired TcB-BsB measurements were obtained. Bland Altman plot for the entire group showed that 54% (33/61) of the pairs of TSB and BsB readings and 66% (56/85) of the pairs of TcB and BsB readings were within the maximum clinically acceptable difference of 35 µmol/L. Pearson r for BsB versus TSB and TcB was 0.54 (P < 0.001) and 0.66 (P < 0.001) respectively. Compared with TSB, the recommended gold standard measure for jaundice, Biliscan has a sensitivity of 76.92% and specificity of 70.83% for jaundice requiring phototherapy. The positive and negative predictive values in term infants were 93.3% and 36.9%, respectively. CONCLUSION: Our results suggest that there is moderate correlation and mediocre agreement between BsB and TSB, as well as TcB. Improvement to the application algorithm and further studies that include a larger population, and a wider range of bilirubin values are necessary before the tool may be considered for use in screening of jaundice in newborns.

Morphine and clinical outcomes in patients with ST segment elevation myocardial infarction treated with fibrinolytic and antiplatelet therapy: Insights from the TREAT trial.

BACKGROUND: Morphine is commonly used to relieve pain, anxiety and dyspnea in STEMI but it lowers blood pressure and delays the activity of oral antiplatelet agents. The impact of morphine on clinical outcomes remains unknown. This analysis was performed to determine if morphine use was associated with increased risk of adverse clinical events among STEMI patients treated with fibrinolytic therapy and clopidogrel or ticagrelor. METHODS: In the Ticagrelor in Patients with ST Elevation Myocardial Infarction Treated with Pharmacological Thrombolysis (TREAT) study, 3799 STEMI patients treated with fibrinolysis were randomized to receive clopidogrel or ticagrelor. Morphine use was left to the discretion of the treating physicians. In this pre-specified analysis, we evaluated clinical outcomes based on the use and timing of morphine administration. Outcomes were stratified by randomized treatment group. Multivariable analysis was performed using Inverse Probability Treatment Weighting (IPTW) weighting. RESULTS: Morphine was used in 53% of patients. After adjustment using IPTW weighting, morphine use was associated with higher hazard of reinfarction at 7 days (HR 4.9, P = .0006) and 30 days (HR 1.7, P = .04), and lower hazard of major bleeding (HR 0.37, P = .006). There was no significant difference in mortality at any time point. CONCLUSIONS: Among patients with STEMI treated with fibrinolytic therapy, morphine use was associated with a higher risk of early reinfarction and a lower risk of major bleeding but no difference in mortality.

Perfectly Alternating Copolymerization of Cyclic Anhydrides and Epoxides with Yttrium ß-Diketiminate Complexes.

Monometallic yttrium ß-diketiminate complexes are active and controlled catalysts for perfectly alternating ring-opening copolymerization of 1-butene oxide and phthalic anhydride under mild conditions. ß-Diketiminate ligands with pendant neutral donors were targeted to identify both the impact of donor strength and number of donors on rates of polymerization and the presence of undesirable side reactions. Initiating groups were also varied between alkyls, chlorides, and alkoxides. In the presence of a cocatalyst, the catalysts studied were active for polymerization with minimal side reactions, whereas lack of cocatalysts led to competing homopolymerization of epoxides. While a greater donor strength and a larger number of donors both increase the rate of polymerization, donor strength generally had a bigger impact when a cocatalyst was used. Additionally, alkoxide and chloride initiators proved to be the fastest, with alkyls being more sluggish. These subtle ligand changes significantly impacting polymerization activity lend promise to the facile tunability of rare earth metal complexes to be highly active for the target copolymerization, which renders further research in this area attractive and timely.

Use and outcomes of dual antiplatelet therapy for acute coronary syndrome in patients with chronic kidney disease: insights from the Canadian Observational Antiplatelet Study (COAPT).

Chronic kidney disease (CKD) increases the risk of adverse outcomes in acute coronary syndrome (ACS). The optimal regimen of dual antiplatelet therapy (DAPT) post-percutaneous coronary intervention (PCI) in CKD poses a challenge due to the increased bleeding and clotting tendencies, particularly since patients with CKD were underrepresented in randomized controlled trials. We examined the practice patterns of DAPT prescription stratified by the presence of CKD. The multicentre prospective Canadian Observational Antiplatelet Study (COAPT) enrolled patients with ACS between December 2011 and May 2013. The present study is a subgroup analysis comparing type and duration of DAPT and associated outcomes among patients with and without CKD (eGFR < 60 ml/min/1.73 m2, calculated by CKD-EPI). Patients with CKD (275/1921, 14.3%) were prescribed prasugrel/ticagrelor less (18.5% vs 25.8%, p = 0.01) and had a shorter duration of DAPT therapy versus patients without CKD (median 382 vs 402 days, p = 0.003). CKD was associated with major adverse cardiovascular events (MACE) at 12 months (p < 0.001) but not bleeding when compared to patients without CKD. CKD was associated with MACE in both patients on prasugrel/ticagrelor (p = 0.017) and those on clopidogrel (p < 0.001) (p for heterogeneity = 0.70). CKD was associated with increased bleeding only among patients receiving prasugrel/ticagrelor (p = 0.007), but not among those receiving clopidogrel (p = 0.64) (p for heterogeneity = 0.036). Patients with CKD had a shorter DAPT duration and were less frequently prescribed potent P2Y12 inhibitors than patients without CKD. Overall, compared with patients without CKD, patients with CKD had higher rates of MACE and similar bleeding rates. However, among those prescribed more potent P2Y12 inhibitors, CKD was associated with more bleeding than those without CKD. Further studies are needed to better define the benefit/risk evaluation, and establish a more tailored and evidence-based DAPT regimen for this high-risk patient group.

Cardiovascular risk factor management in patients with diabetes: Does management differ with disease duration?

AIMS: Our objective was to examine risk factor modification targets and treatment in relation to duration of diabetes. METHODS: The Diabetes Mellitus Status in Canada (DM-SCAN) study collected data on 5109 patients with type 2 diabetes mellitus (T2DM) in 2012 in primary care. We compared the prevalence of vascular complications, treatment targets, and interventions between patients with diagnosed diabetes duration ≤10 and > 10 years. RESULTS: Physicians more frequently assigned HbA1c (glycated hemoglobin) targets of 7.1-8.5% (54-69 mmol/mol) to patients with longer duration of diabetes (n = 1647) (19.8% vs 9.5%, p < 0.001). Patients with longer duration of diabetes were less likely to achieve HbA1c targets of ≤7.0% (53 mmol/mol) (39% vs. 55%, p < 0.001), had similar likelihood of achieving blood pressure targets of ≤130/80 mmHg (38% vs. 36%, p = 0.26) and were more likely to achieve LDL-C targets of ≤2.0 mmol/L (≤77.3 mg/dL) (63% vs. 53%, p < 0.001) compared to patients with shorter duration of diabetes (n = 3462). Achievement of all three targets between both groups were similar (13% vs. 13%, p = 0.82). Overall, patients with longer duration of diabetes were more likely to be prescribed anti-hyperglycemic, anti-hypertensive, lipid-lowering medications and referred for diabetes education. CONCLUSIONS: Only 13% of patients achieved glycemic, blood pressure, and LDL-C targets irrespective of duration of diabetes. Despite being managed with more medications, patients with longer duration of diabetes were less likely to achieve glycemic targets. More focus is needed on developing methods to bridge best care and real-world practice.

Treatment Inertia in Patients With Familial Hypercholesterolemia.

Background We studied care gap in patients with familial hypercholesterolemia (FH) with respect to lipid-lowering therapy. Methods and Results We enrolled patients with cardiovascular disease (CVD) or FH and low-density lipoprotein-cholesterol >2.0 mmol/L despite maximally tolerated statin therapy. During follow-up physicians received online reminders of treatment recommendations of 2009 patients (median age, 63 years, 42% women), 52.4% had CVD only, 31.7% FH only, and 15.9% both CVD and FH. Patients with FH were younger and more likely to be women and non-White with significantly higher baseline low-density lipoprotein-cholesterol level (mmol/L) as compared with patients with CVD (FH 3.92±1.48 versus CVD 2.96±0.94, P<0.0001). Patients with FH received less statin (70.6% versus 79.2%, P=0.0001) at baseline but not ezetimibe (28.1% versus 20.4%, P=0.0003). Among patients with FH only, 45.3% were at low-density lipoprotein target (≥ 50% reduction from pre-treatment level or low-density lipoprotein <2.5 mmol/L) at baseline and increasing to 65.8% and 73.6% by visit 2 and 3, respectively. Among patients with CVD only, none were at recommended level (≤2.0 mmol/L) at baseline and 44.3% and 53.3% were at recommended level on second and third visit, respectively. When primary end point was analyzed as a difference between baseline and last available follow-up observation, only 22.0% of patients with FH only achieved it as compared with 45.8% with CVD only (P<0.0001) and 55.2% with both FH+CVD (P<0.0001). Conclusions There is significant treatment inertia in patients with FH including those with CVD. Education focused on patients with FH should continue to be undertaken.

Use of antithrombotic therapy for secondary prevention in patients with stable atherosclerotic cardiovascular disease: Insights from the COordinated National Network to Engage Cardiologists in the antithrombotic Treatment of patients with CardioVascular Disease (CONNECT-CVD) study.

BACKGROUND: Although acetylsalicylic acid is the most commonly used antithrombotic agent for the secondary prevention of cardiovascular events, residual atherothrombotic risk has prompted a guideline recommendation for the addition of dual antiplatelet therapy (DAPT) or dual pathway inhibition (DPI) in high vascular risk patients. Accordingly, the CONNECT CVD quality enhancement initiative provides a contemporary "snapshot" of the clinical features and antithrombotic management of atherosclerotic cardiovascular disease (ASCVD) patients in Canada. METHODS: Canadian cardiologists (49 cardiologists from six provinces) undertook a retrospective chart audit of 10 ASCVD patients in their outpatient practice who met the Cardiovascular Outcomes for People Using Anticoagulation Strategy-like criteria from May 2018 to April 2019. RESULTS: Of the 492 (two cardiologists provided 11 patients) enroled, average age was 70 years, 25% were female, 39% had diabetes and 20% had atrial fibrillation. Prior revascularisation was common (percutaneous coronary artery intervention 61%, coronary artery bypass graft 39%), with 31% having multivessel disease. A total of 47% of patients had a Reduction of Atherothrombosis for Continued Health bleeding score of ≥11 (~2.8% risk of serious bleeding at 2 years). Single antiplatelet therapy (SAPT) alone was most commonly used (62%), while 22% were on DAPT alone. In total, 22% were on oral anticoagulation (OAC), with 16% being on non-vitamin K oral anticoagulant alone, 5% on DPI and 1% received triple therapy. CONCLUSIONS: In contemporary Canadian clinical practice of stable ASCVD patients, a large number of patients receive antithrombotic therapy other than SAPT. Further efforts are required to guide the appropriate selection of patients in whom more potent antithrombotic therapies may safely reduce residual risk.

Detection of atrial fibrillation in asymptomatic at-risk individuals.

BACKGROUND: Undiagnosed atrial fibrillation (AF) exposes unsuspecting patients to elevated stroke risks. The optimal algorithm for identifying patients who should be screened for AF remains undetermined. The objective of this study is to determine the AF burden in an asymptomatic, at-risk population. We also sought to investigate potential predictors of undiagnosed AF. METHODS: This registry is a prospective observational study assessing continuous ECG monitoring in screening for AF using a wearable single lead 7-day continuous monitoring device. Patients included were asymptomatic individuals, at risk for AF as determined by either 1) ≥65 years of age with ≥1 high risk factor or; 2) ≥75 years of age and ≥2 moderate risk factors. A multivariable logistic regression was used to explore the predictive value of certain patient characteristics in identifying patients susceptible to have undiagnosed AF. RESULTS: Among the 942 patients included, 25 patients (2.7%) had evidence of AF detected. Only 8 patients had AF duration ≥24 h. History of perioperative AF (OR: 3.25, 95%CI: 1.08-9.79, p = 0.036), age over 85 (OR: 4.71, 95%CI: 1.31-16.92, p = 0.017) and absence of cardiovascular disease (CVD) (OR: 0.27, 95%CI: 0.10-0.76, p = 0.013) were found to be predictive of undiagnosed AF. CONCLUSION: This study demonstrates the feasibility of office-based AF screening in at-risk population. The low rate of AF detection suggests that the optimal algorithm for identifying asymptomatic patients who would benefit from continuous screening remains unclear. Advanced age, history of perioperative AF and absence of CVD are variables that could be explored further.

Contemporary use of guideline-based higher potency P2Y12 receptor inhibitor therapy in patients with moderate-to-high risk non-ST-segment elevation myocardial infarction: Results from the Canadian ACS reflective II cross-sectional study.

BACKGROUND: After myocardial infarction, guidelines recommend higher-potency P2Y12 receptor inhibitors, namely ticagrelor and prasugrel, over clopidogrel. HYPOTHESIS: We aimed to determine the contemporary use of higher-potency antiplatelet therapy in Canadian patients with non-ST-elevation myocardial infarction (NSTEMI). METHODS: A total of 684 moderate-to-high risk NSTEMI patients were enrolled in the prospective Canadian ACS Reflective II registry at 12 Canadian hospitals and three clinics in five provinces between July 2016 and May 2018. Multivariable logistic regression modeling was performed to assess factors independently associated with higher-potency P2Y12 receptor inhibitor use at discharge. RESULTS: At hospital discharge, 78.3% of patients were treated with a P2Y12 receptor inhibitor. Among patients discharged on a P2Y12 receptor inhibitor, use of higher-potency P2Y12 receptor inhibitor was 61.4%. After adjustment, treatment in-hospital with PCI (OR 4.48, 95%CI 3.34-6.03, p < .0001) was most strongly associated with higher use of higher-potency P2Y12 receptor inhibitor, while oral anticoagulant use at discharge (OR 0.03, 95%CI 0.01-0.12, p < .0001), and atrial fibrillation (OR 0.40, 95%CI 0.17-0.98, p = .046) were most strongly associated with lower use of higher-potency P2Y12 receptor inhibitor. Use of higher-potency P2Y12 receptor inhibitor varied across provinces (range, 21.6%-78.9%). DISCUSSION: In contemporary Canadian practice, approximately 60% of moderate-to-high risk NSTEMI patients discharged on a P2Y12 receptor inhibitor are treated with a higher-potency P2Y12 receptor inhibitor. In addition to factors that increase risk of bleeding, interprovincial differences in practice patterns were associated with use of higher-potency P2Y12 receptor inhibitor at discharge. Opportunities remain for further optimization of evidence-based, guideline-recommended antiplatelet therapy use.

Glycemic Control and Cardiovascular Risk Factor Management in Adults With Type 2 Diabetes With and Without Chronic Kidney Disease Before Sodium-Glucose Cotransporter Protein 2 Inhibitors: Insights From the Diabetes Mellitus Status in Canada Survey.

OBJECTIVES: Optimal control of cardiovascular risk factors in adults with type 2 diabetes (T2D) and chronic kidney disease (CKD) is challenging. Limited data are available from the primary care setting on achievement of guideline-recommended targets in this population before the use of sodium-glucose cotransporter protein 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists. METHODS: The Diabetes Mellitus Status in Canada survey included 5,172 patients with T2D seen by primary care physicians (PCPs) in November 2012. We compared treatment targets and therapeutic interventions in patients with and without CKD. RESULTS: Compared with those without CKD (n=3,804), patients with CKD (n=1,368) were older, more likely to be female, had a longer duration of diabetes and had more vascular complications. Patients with CKD more frequently had a less stringent glycated hemoglobin (A1C) target of ≤8.0% set by PCPs (10.3% vs 20%, p<0.001), and fewer patients with CKD met the A1C target of ≤7.0% (50.9% vs 47.1%, p=0.016) than those without CKD. Both groups had a similar likelihood of achieving the blood pressure (BP) target of ≤130/80 mmHg (36.8% vs 34.8%, p=0.20), whereas patients with CKD more frequently achieved a low-density lipoprotein cholesterol target of ≤2.0 mmol/L (54.8% vs 61.3%, p<0.001). Overall, only 12.5% in both groups achieved all 3 targets (12.3% vs 13.3%, p=0.33). CONCLUSIONS: Only 1 of 8 patients with T2D achieved optimal glycemic, BP and cholesterol targets, regardless of the presence or absence of CKD. Although more medical interventions were used in patients with CKD, a lower proportion achieved guideline-recommended targets for A1C. These findings provide a benchmark for future comparison.

Reducing the incidence of phlebitis in medical adult inpatients with peripheral venous catheter care bundle: a best practice implementation project.

BACKGROUND: One major complication of the insertion of a peripheral venous catheter (PVC) is phlebitis, often resulting in delay of treatment, increased healthcare costs and prolonged hospitalization. AIMS: The current study sought to evaluate the effectiveness of a standardized PVC care bundle in increasing the compliance of PVC care and assessment and reduce the occurrences of phlebitis rates. METHODS: A pre and postimplementation audit approach was used in this study and adopted the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice program. This study was carried out in three phases over a 10-month period, from March 2017 to December 2017 across three medical wards in a hospital in Singapore with a sample size of 90 patients. The study involved educating nurses on phlebitis assessment, implementing a PVC care bundle and monitoring compliance. An audit tool comprising four criteria from the Joanna Briggs Institute Practical Application of Clinical Evidence System was developed. RESULTS: One-month and 3-month postimplementation findings revealed significant improvement in Criteria 1, 3 and 4 (P < 0.001) but no significant improvement in Criterion 2 (P > 0.05). Six-month postimplementation findings showed significant improvement in all four criteria (P < 0.05). An interesting finding was that the number of reported occurrences of phlebitis increased after implementing the PVC care bundle. DISCUSSION: The increase in phlebitis rates could be attributed to the care bundle facilitating prompt and early identification of phlebitis. Despite the initial increase in occurrences 1 month post implementation, the general effectiveness of the care bundle in reducing occurrences of phlebitis was seen 6 months post implementation. The effectiveness of the care bundle to reduce phlebitis rates may be even more evident across a longer implementation period. CONCLUSION: The current study showed that the implementation of a standardized PVC care bundle can significantly enhance the assessment and identification process of phlebitis and can aid in reducing the incidence of phlebitis. The nurses' compliance in practicing the PVC care bundle was determined by the post and preimplementation audits, thus, the audit approach was beneficial in translating evidence into practice.

Conducive environments reduce sleep disturbances and improve sleep quality: a quality improvement project.

AIM: The current implementation project aimed to improve patients' sleep quality in a hospital by implementing targeted interventions to reduce sleep disturbances. METHODS: The Silent Night project was implemented in two general units of an academic tertiary hospital. The project comprised three phases: preimplementation, implementation, and postimplementation. Patient surveys were administered to obtain patients' perspectives on the sources of noise disturbances at night. Noise-monitoring machines were installed in two wards to obtain objective data on noise levels at night. Concurrently, data were collected on noise-generating activities that were observed. RESULTS: The overall quality of sleep reported by patients improved by 17% (from 73.5 to 88.9%). Patients' survey reported reduced noise disturbances from direct care activities, environmental noise and medical equipment alarms. The mean noise level in the orthopedics unit reduced significantly from 57.04 to 55.22 dB with a corresponding decrease in noise generating activities by 60% (from 362 to 144). In the geriatric unit, the mean noise level increased from 51.36 to 53.12 dB but is within the National Environmental Agency's permissible noise level of 55 dB even though the noise generating activities reduced significantly by 92.2% (from 954 to 74). CONCLUSION: The 'Silent Night' project has successfully reduced noise disturbances generating from environment and nursing care activities and improved patients' sleep quality in the hospital. Sharing sessions regarding sources of noise and the 'Silent Night' poster promoted the awareness of noise disturbances in healthcare professionals, visitors, and patients.

Screening for congenital heart disease in a Singapore neonatal unit.

INTRODUCTION: Congenital heart disease (CHD) is a leading cause of infant mortality. The aim of this study was to evaluate the efficacy of a neonatal screening programme for CHD before the introduction of pulse oximetry. METHODS: This was a retrospective review of live births in the period 2003-2012. Cases of CHD were detected through prenatal ultrasonography and/or postnatal examination, and confirmed using two-dimensional echocardiography. Data was rigorously checked against multiple sources. The antenatal detection rate, sensitivity, specificity, predictive values and likelihood ratios of the screening programme were analysed for all cases of CHD and critical CHD. RESULTS: The incidence of CHD was 9.7 per 1,000 live births. The commonest CHD was ventricular septal defect (54.8%). The antenatal detection rate was three times higher in the critical CHD group (64.0%) compared to the group as a whole (21.1%). The sensitivity and specificity of screening was 64.5% and 99.7% for all CHD, and 92.9% and 99.1% for the critical CHD group, respectively. The positive likelihood ratio was 215 and 103, while the negative likelihood ratio was 0.36 and 0.07 for all CHD and critical CHD, respectively. CONCLUSION: The CHD screening programme had excellent specificity but limited sensitivity. The high positive likelihood ratios indicate that where sufficient risk factors for CHD are present, a positive result effectively confirms the presence of CHD. The low negative likelihood ratio for critical CHD indicates that, where prior suspicion for critical CHD is low, a negative result is reassuring.

Antithrombotic Therapy After Percutaneous Coronary Intervention in Patients With Atrial Fibrillation: Findings From the CONNECT AF+PCI Study.

BACKGROUND: In patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), selecting an antithrombotic regimen requires balancing risks of ischemic cardiac events, stroke, and bleeding. METHODS: We studied 467 patients with AF undergoing PCI in the time period from December 2015 to July 2018 identified via a chart audit by 47 Canadian cardiologists in the CONNECT AF+PCI (the Coordinated National Network to Engage Interventional Cardiologists in the Antithrombotic Treatment of Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) study, to determine patterns of initial antithrombotic therapy selection. RESULTS: The median (25th, 75th percentile) CHADS2 score was 2 (1, 3), and PCI was performed in the setting of acute coronary syndrome in 62.1%. Triple antithrombotic therapy (TAT) was the initial treatment in 62.7%, dual-pathway therapy in 25.7%, and dual antiplatelet therapy in 11.6%, with a temporal increase in use of dual-pathway therapy during the course of the study; median intended TAT duration was 1 (1, 3) month. Compared with patients selected for TAT, patients selected for dual-pathway therapy were less likely to have prior myocardial infarction (35.8% vs 25.8%, P = 0.045) and prior PCI (33.8% vs 23.3%, P = 0.03), and they received shorter total length of stents (38 [23, 56] vs 30 [20, 46] mm, P = 0.03). Patients selected for dual-pathway therapy had a higher prevalence of prior stroke/transient ischemic attack (13.0% vs 23.3%, P = 0.01). There was no difference in prevalence of anemia (21.5% vs 25.8%, P = 0.30). Use of dual-pathway therapy was similar among patients with acute coronary syndrome and those with stable disease (24.1% vs 28.2%, P = 0.32). CONCLUSIONS: Approximately one-quarter of AF patients undergoing PCI are treated with dual-pathway therapy in Canadian practice, with its use increasing during the studied period. Patients selected for dual-pathway therapy have less-complex coronary disease history and intervention.

INTRODUCTION: Les patients atteints de fibrillation auriculaire (FA) qui subissent une intervention coronarienne percutanée (ICP) et choisissent un schéma posologique antithrombotique ont besoin de peser les risques d'événements cardiaques d'origine ischémique, d'accidents vasculaires cérébraux et d'hémorragies. MÉTHODES: Les 467 patients atteints de FA ayant subi une ICP de décembre 2015 à juillet 2018 qui ont fait l'objet de notre étude ont été trouvés lors de la vérification des dossiers par 47 cardiologues canadiens de l'étude CONNECT AF+PCI ( Co ordinated N ational N etwork to E ngage Interventional C ardiologists in the Antithrombotic T reatment of Patients With A trial F ibrillation Undergoing P ercutaneous C oronary I ntervention) pour déterminer les schémas de sélection du traitement antithrombotique initial. RÉSULTATS: Le score CHADS2 médian (25e, 75e percentile) était de 2 (1, 3), et l'ICP avait été réalisée dans le cadre du syndrome coronarien aigu chez 62,1 % des patients. La trithérapie antithrombotique (TTA) était le traitement initial chez 62,7 % des patients, la bithérapie, chez 25,7 % des patients, et la bithérapie antiplaquettaire, chez 11,6 % des patients, mais il y avait une augmentation temporelle dans l'utilisation de la bithérapie durant l'étude; la durée médiane prévue de la TTA était de 1 (1, 3) mois. Comparativement aux patients sélectionnés pour la TTA, les patients sélectionnés pour la bithérapie étaient moins susceptibles d'avoir eu un infarctus du myocarde précédent (35,8 % vs 25,8 %, P = 0,045) et une ICP précédente (33,8 % vs 23,3 %, P = 0,03), et recevaient des endoprothèses de longueur totale plus courte (38 [23, 56] vs 30 [20, 46] mm, P = 0,03). Les patients sélectionnés pour la bithérapie montraient une prévalence plus élevée d'accidents vasculaires cérébraux/accidents ischémiques transitoires (13,0 % vs 23,3 %, P = 0,01). Il n'existait aucune différence dans la prévalence de l'anémie (21,5 % vs 25,8 %, P = 0,30). L'utilisation de la bithérapie était similaire chez les patients atteints d'un syndrome coronarien aigu et chez les patients dont la maladie était stable (24,1 % vs 28,2 %, P = 0,32). CONCLUSIONS: Dans la pratique canadienne, environ le quart des patients atteints de FA qui subissent une ICP sont traités par bithérapie, mais durant la période étudiée, son utilisation avait augmenté. Les patients sélectionnés pour la bithérapie ont des antécédents et des interventions liées aux maladies coronariennes moins complexes.
