RESUMO

PURPOSE: This study seeks to improve the understanding of physician leaders' leadership work challenges. DESIGN/METHODOLOGY/APPROACH: The subjects of the empirical study were physician leaders (n = 23) in the largest central hospital in Finland. FINDINGS: A total of five largely identity-related, partially paradoxical dilemmas appeared regarding why working as "just a leader" is challenging for physician leaders. First, the dilemma of identity ambiguity between being a physician and a leader. Second, the dilemma of balancing the expected commitment to clinical patient work by various stakeholders and that of physician leadership work. Third, the dilemma of being able to compensate for leadership skill shortcomings by excelling in clinical skills, encouraging physician leaders to commit to patient work. Fourth, the dilemma of "medic discourse", that is, downplaying leadership work as "non-patient work", making it inferior to patient work. Fifth, the dilemma of a perceived ethical obligation to commit to patient work even if the physician leadership work would be a full-time job. The first two issues support the findings of earlier research, while the remaining three emerging from the authors' analysis are novel. PRACTICAL IMPLICATIONS: The authors list some of the practical implications that follow from this study and which could help solve some of the challenges. ORIGINALITY/VALUE: This study explores physician leaders' leadership work challenges using authentic physician leader data in a context where no prior empirical research has been carried out.

RESUMO

BACKGROUND: Claudication and critical limb threatening ischemia are significant causes of mortality in the elderly. The gold standard of superficial femoral artery (SFA) revascularization is thus far considered to be the femoropopliteal bypass. The aim of this study was to compare mid-term patency between drug-eluting stents (DESs) and prosthetic bypass grafts (BSX). Studies have reported comparable results for both the methods. METHODS: Forty-six patients with claudication or rest pain due to a 5-25 cm SFA occlusion were randomized between DES and BSX groups. The follow-up period was 24 months, and the primary outcome measure was overall patency. Secondary outcome measures were primary and primary assisted patency, change in ankle-brachial index (ABI), and amputation-free survival. RESULTS: Forty-one patients were eventually analyzed. Six-month secondary patency was 91% (DES) versus 83% (BSX) (P = 0.450). The corresponding numbers at 12 months in the DES and BSX groups were 74% and 80% (P = 0.750), respectively. At 24 months, the respective numbers were 56% and 71% (P = 0.830). There were no statistically significant differences in primary or assisted primary patency at 1, 6, or 12 months. CONCLUSION: There were no demonstrable differences in patency rates or clinical outcomes such as ABI or major amputations between DES and BSX. Although underpowered, the results suggest noninferiority of the DES compared with prosthetic bypass surgery. TRIAL REGISTRATION: The trial was preregistered at ClinicalTrials.org (NCT01450722).

RESUMO

CONTEXT: Atrial fibrillation (AF) is the most common arrhythmia to occur after cardiac surgery. An exaggerated inflammatory response has been proposed to be one etiological factor. OBJECTIVE: To test whether intravenous corticosteroid administration after cardiac surgery prevents AF after cardiac surgery. DESIGN, SETTING, AND PATIENTS: A double-blind, randomized multicenter trial (study enrollment August 2005-June 2006) in 3 university hospitals in Finland of 241 consecutive patients without prior AF or flutter and scheduled to undergo first on-pump coronary artery bypass graft (CABG) surgery, aortic valve replacement, or combined CABG surgery and aortic valve replacement. INTERVENTION: Patients were randomized to receive either 100-mg hydrocortisone or matching placebo as follows: the first dose in the evening of the operative day, then 1 dose every 8 hours during the next 3 days. In addition, all patients received oral metoprolol (50-150 mg/d) titrated to heart rate. MAIN OUTCOME MEASURE: Occurrence of AF during the first 84 hours after cardiac surgery. RESULTS: The incidence of postoperative AF was significantly lower in the hydrocortisone group (36/120 [30%]) than in the placebo group (58/121 [48%]; adjusted hazard ratio, 0.54; 95% confidence interval, 0.35-0.83; P = .004; number needed to treat, 5.6). Compared with placebo, patients receiving hydrocortisone did not have higher rates of superficial or deep wound infections, or other major complications. CONCLUSION: Intravenous hydrocortisone reduced the incidence of AF after cardiac surgery. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00442494.

RESUMO

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia to occur after cardiac surgery, with an incidence of 20% to 40%. AF is associated with postoperative complications, including increased risk of stroke and need of additional treatment, as well as prolonged hospital stay and increased costs. It has been shown that prophylactic oral administration of beta-blocker therapy reduces the incidence of postoperative AF after cardiac surgery. However, it is possible that absorption of drugs is impaired after cardiopulmonary perfusion associated with cardiac surgery. The purpose of this prospective, controlled, randomized trial was to study compare intravenous and per oral metoprolol administration in the prevention of AF after cardiac surgery. METHODS AND RESULTS: 240 consecutive patients who were scheduled to undergo their first on-pump coronary artery bypass graft (CABG), aortic valve replacement, or combined aortic valve replacement and CABG were randomized to receive 48-hour infusion of metoprolol or oral metoprolol starting on the first postoperative morning. Patients were excluded if they had contraindications for beta-blocker or had to stay >1 day in the intensive care unit. Dosage of metoprolol was adjusted according to heart rate. The dosage was 1 to 3 mg/h in the intravenous group and from 25 mg twice per day to 50 mg 3 times per day in the oral group. The incidence of postoperative AF was significantly lower in the intravenous group than in the oral group (16.8% versus 28.1%, P=0.036). No serious adverse effects were associated with intravenous metoprolol therapy. CONCLUSIONS: Our study suggests that intravenous metoprolol is well-tolerated and more effective than oral metoprolol in the prevention of AF after cardiac surgery.
