Progress in a social work writing course: Self-efficacy, course objectives, and skills

Although instructors express concerns about social work students’ writing skills, little research has been conducted. One remedy is a social work-focused writing course. This study assessed a required writing course with a sample of 49 baccalaureate students. From online pre- and post-test surveys, two student outcomes improved significantly: self-reported scores for writing self-efficacy and competence in course objectives. On-demand writing samples improved significantly based on anonymous rating by the course instructors; however, blind ratings found gains but not at a significant level. Improved outcomes were not associated with demographic or background characteristics. We discuss limitations of the study and implications for social work education

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

The effect of intended duration of clopidogrel use on early and late mortality and major adverse cardiac events in patients with drug-eluting stents

Background: The optimal duration of clopidogrel use for prevention of stent thrombosis with drug-eluting stent (DES) use is uncertain. Our objective was to determine whether the planned duration of clopidogrel at the time of percutaneous coronary intervention affected patient outcomes. Methods: We analyzed data from 2,980 patients who underwent percutaneous coronary intervention in the Melbourne Interventional Group registry who had 12-month follow-up. We compared outcomes at 30 days and 12 months according to planned duration of clopidogrel use. Results: Twelve-month mortality was significantly lower in patients with a DES with a longer (=12 months) planned duration of clopidogrel when compared with a shorter (=6 months) planned duration (2.8% vs 5.3%, P = .012). However, myocardial infarction, target-vessel revascularization, and overall major adverse cardiac events were similar in the longer- and shorter-duration clopidogrel strategies. In contrast, in patients receiving a bare-metal stent, mortality at 12 months was similar among the clopidogrel-duration strategies. Kaplan-Meier analysis demonstrated improved cumulative survival with planned clopidogrel use of =12 months (log rank P = .017), and the propensity score-adjusted odds ratio was 0.59 (95% confidence interval 0.35-0.99, P = .04). Premature cessation of clopidogrel in DES patients was documented in 5.2% of patients alive at 30-day follow-up, and these patients had increased 12-month mortality (10.6% vs 1.4%, P < .0001) and major adverse cardiac events (22.4% vs 12.0%, P = .005). Conclusions: These data suggest that in patients treated with DES, longer (=12 months) planned duration of clopidogrel results in reduced 12-month mortality and that premature cessation of clopidogrel results in significantly higher event rates. Randomized studies are urgently needed to address this issue. © 2009 Mosby, Inc

Outcomes after percutaneous coronary intervention of ostial lesions in the era of drug-eluting stents

Background: Ostial lesions are a difficult subset associated with suboptimal outcomes after percutaneous coronary intervention (PCI). The aim of this study was to analyze outcomes of ostial lesions in contemporary Australian interventional practice. Methods: The study population comprised 1,713 consecutive patients who underwent PCI for proximal lesions of the left anterior descending, left circumflex, and right coronary arteries, who were prospectively enrolled in the Melbourne Interventional Group Registry (February 2004-December 2006). We compared the in-hospital, 30-day, and 1-year outcomes of the 109 patients undergoing PCI for ostial, with the 1,604 patients with proximal nonostial lesions. Left main and bifurcation lesions were excluded. Results: Patients in the ostial group were older (mean age 68.8 ± 11 vs. 64.9 ± 12 years; P = 0.001), and there was a greater proportion of women (38.5% vs. 28.0%; P = 0.021). Other clinical characteristics were similar. The nonostial group were more likely receive a stent (94.6% vs. 87.2%; P = 0.005) but drug-eluting stents (DES) were deployed more often in the ostial group (47.9% vs. 66.1%; P < 0.0001). There was lower procedural success, with no significant difference in in-hospital death, bleeding or emergency PCI, but unplanned in-hospital coronary artery bypass grafting was more frequent in the ostial group (4.8% vs. 1.0%; P = 0.007). There was no difference in 30-day major adverse cardiac events. However, 12-month death (8.8% vs. 4%, log rank P = 0.032) and MACE (24.2% vs. 13.8%, log rank P = 0.005) were higher in the ostial group than the nonostial group with trends to increased incidence of myocardial infarction (6.6% vs. 4.7%, P = NS), and target vessel revascularization (13.2% vs. 7.9%, P = NS). Conclusion: In contemporary, Australian interventional practice, PCI for ostial lesions is associated with a high incidence of adverse outcome at one year despite the introduction of DES. © 2009 Wiley-Liss, Inc

Use of drug-eluting stents in Victorian public hospitals

OBJECTIVE: We aimed to assess the pattern of use of drug-eluting stents (DESs) in patients undergoing percutaneous coronary interventions (PCIs) in Victorian public hospitals. DESIGN, SETTING AND PATIENTS: Prospective study comparing the use of one or more DESs versus bare-metal stents (BMSs) only, in consecutive patients undergoing 2428 PCIs with stent implantation from 1 April 2004 to 31 December 2005 at seven Victorian public hospitals. MAIN OUTCOME MEASURES: Adherence to current Victorian Department of Human Services guidelines which recommend DES use in patients with high-risk features for restenosis (diabetes, small vessels, long lesions, in-stent restenotic lesions, chronic total occlusions and bifurcation lesions). RESULTS: Of the 2428 PCIs performed, at least one DES was implanted in 1101 (45.3%) and BMSs only were implanted in 1327 (54.7%). In 87.7% (966/1101) of PCI with DESs, there was at least one criterion for high risk of restenosis. DESs were more likely to be used in patients with diabetes (risk ratio [RR], 2.45; 95% CI, 2.02-2.97), small vessels (RR, 3.35; 95%CI, 2.35-4.76), long lesions (RR, 3.87; 95% CI, 3.23-4.65), in-stent restenotic lesions (RR, 3.98; 95%CI, 2.67-6.06), chronic total occlusions (RR, 1.30; 95% CI, 0.51-2.88) and bifurcation lesions (RR, 2.23; 95%CI, 1.57-3.17). However, 66.2% (1608/2428) of all PCIs were in patients eligible for DESs according to Victorian guidelines, and in 39.9% (642/1608) of these PCIs, a BMS was used. CONCLUSION: In Victorian public hospitals, DESs have been largely reserved for patients at high risk of restenosis in accordance with Department of Human Services guidelines. However, many patients with high-risk criteria for restenosis did not receive DESs. Greater use of DESs in these patients may improve outcomes by reducing the need for repeat revascularisation.5 page(s
