Scientific activity and working hours of physicians in university hospitals: results from the Innsbruck and Salzburg physician lifestyle assessment (TISPLA).

OBJECTIVE: Controllable lifestyle has become an important factor influencing career decision-making among physicians. In academic medicine, doctors are required to combine both patient care and research in their daily routine. Insufficient release of clinicians for research during contracted work hours may lead to increased weekly working hours in academic medical centers and deter medical graduates from academia. We tested for an association between numbers of scientific publications and an increased hourly workload among physicians. METHODS: This was a cross-sectional online survey among all salaried physicians working in the university hospitals of Innsbruck and Salzburg, Austria. The main outcome measures were the self-reported total number of scientific papers published in peer-reviewed medical journals over the past two years and self-reported working hours. RESULTS: Of 590 returned surveys, 393 were fully completed and included in the study. The sample was stratified into three groups according to scientific output in the past two years: Group A, >/= 6 publications; Group B, 1-5 publications; Group C, no publications. Men were more likely than women to have a scientific publication: in Group A there was a male predominance of 75%, whereas in Group C only 48% were men (P = 0.0034). A total of 59% (n = 232) of all participants had not published a scientific article in the past two years (Group C) and worked a mean of 58.3 +/- 12 h/week. Physicians in Group B (n = 113) had published 2.4 +/- 1.4 papers and worked 62.8 +/- 12.9 h/week; those in Group A (n = 48) had published 11.5 +/- 6.6 papers and worked 73 +/- 13.1 h/week (P < 0.0001). In Group A, research accounted for only 13.3% of total work time but for 60% of overtime hours, reflecting the fact that research was mainly performed during overtime. CONCLUSION: Research activity among clinicians in academic medical centers is associated with significantly increased overtime hours. Measures need to be taken to allow medical graduates an academic career at reasonable impairment of personal lifestyle.

Phase 1A safety assessment of intravenous amitriptyline.

UNLABELLED: The antidepressant amitriptyline is used as an adjuvant in the treatment of chronic pain. Among its many actions, amitriptyline blocks Na+ channels and nerves in several animal and human models. As perioperative intravenous lidocaine has been suggested to decrease postoperative pain, amitriptyline, because of its longer half-life time, might be more useful than lidocaine. However, the use of intravenous amitriptyline is not approved by the US Food and Drug Administration. We therefore investigated the adverse effects of preoperative intravenous amitriptyline in a typical phase 1A trial. After obtaining written Food and Drug Administration and institutional review board approval, we obtained written consent for preoperative infusion of amitriptyline in an open-label, dose-escalating design (25, 50, and 100 mg, n=5 per group). Plasma levels of amitriptyline/nortriptyline were determined, and adverse effects were recorded in a predetermined symptom list. Infusion of 25 and 50 mg amitriptyline appears to be well tolerated; however, the study was terminated when 1 subject in the 100-mg group developed severe bradycardia. Intravenous infusion of amitriptyline (25 to 50 mg over 1 hour) did not create side effects beyond dry mouth and drowsiness, or dizziness, in 2 of our 10 otherwise healthy participants receiving the 25- to 50-mg dose. An appropriately powered future trial is necessary to determine a potential role of amitriptyline in decreasing postoperative pain. PERSPECTIVE: Amitriptyline potently blocks the persistently open Na+ channels, which are known to be instrumental in various pain states. As this occurs at very low plasma concentrations, a single preoperative intravenous infusion of amitriptyline could provide long-lasting pain relief and decrease the incidence of chronic pain.
