Multicenter Study Clinical Trial Controlled Clinical Trial
Advanced cardiac life support in out-of-hospital cardiac arrest.
The Ontario Prehospital Advanced Life Support (OPALS) Study tested the incremental effect on the rate of survival after out-of-hospital cardiac arrest of adding a program of advanced life support to a program of rapid defibrillation. ⋯ The addition of advanced-life-support interventions did not improve the rate of survival after out-of-hospital cardiac arrest in a previously optimized emergency-medical-services system of rapid defibrillation. In order to save lives, health care planners should make cardiopulmonary resuscitation by citizens and rapid-defibrillation responses a priority for the resources of emergency-medical-services systems.

Randomized Controlled Trial Multicenter StudyThe Clots in Legs Or sTockings after Stroke (CLOTS) 3 trial: a randomised controlled trial to determine whether or not intermittent pneumatic compression reduces the risk of post-stroke deep vein thrombosis and to estimate its cost-effectiveness.
Venous thromboembolism (VTE) is a common cause of death and morbidity in stroke patients. There are few data concerning the effectiveness of intermittent pneumatic compression (IPC) in treating patients with stroke. ⋯ Further research should test whether or not IPC improves survival in other groups of high-risk hospitalised medical patients. In addition, research into methods to improve adherence to IPC might increase the benefits of IPC in stroke patients.

Randomized Controlled Trial Multicenter Study
Frailty Related to Anesthesia guided by the Index "bispectraL" (FRAIL) study: study protocol for a randomized controlled trial.
Currently, patients older than 60 years of age represent 25% of the population and are at an increased risk during surgery. Therefore, reducing postoperative morbidity and mortality is a major concern in medical research and practice. Dependence on caregivers and cognitive impairment represent two major risk factors in the elderly, especially in frail patients after surgery under general anesthesia. In this context, continuous monitoring of the depth of anesthesia using a bispectral index (BIS) sensor may reduce the occurrence of impairments by gaining better control of the anesthetic depth. The first aim of this study is to compare manual versus automated administration of intravenous anesthetics with regard to 6-month functional decline in persons aged 70 years and older. The secondary objective includes an evaluation of the influence of the frail phenotype on self-sufficiency in elderly patients after general anesthesia. ⋯ This clinical study is designed to detect any postoperative complications and deaths related to the performance of the general anesthesia guided by the BIS sensor and the preoperative functional status of the elderly: robust, pre-frail, or frail.

Randomized Controlled Trial Multicenter Study Comparative Study
Effectiveness of a multifactorial falls prevention program in community-dwelling older people when compared to usual care: study protocol for a randomised controlled trial (Prevquedas Brazil).
Falling in older age is a major public health concern due to its costly and disabling consequences. However very few randomised controlled trials (RCTs) have been conducted in developing countries, in which population ageing is expected to be particularly substantial in coming years. This article describes the design of an RCT to evaluate the effectiveness of a multifactorial falls prevention program in reducing the rate of falls in community-dwelling older people. ⋯ This study is the first trial to be conducted in Brazil to evaluate the effectiveness of an intervention to prevent falls. If proven to reduce falls this study has the potential to benefit older adults and assist health care practitioners and policy makers to implement and promote effective falls prevention interventions.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial[Multicentre study of comparative efficacy of meropenem and combined regimens for empirical antibacterial therapy of severe nosocomial infections: results of clinical and pharmacoeconomic analysis].
Adequacy and effectiveness of empirical antibacterial therapy of severe nosocomial infections with meropenem vs. combined regimens of antibacterial therapy were investigated and the ratio of the cost and effectiveness of the compared regimens was evaluated. A prospective, randomized, open, comparative study of two initiative regimens of empirical antibacterial therapy of severe nosocomial infections was performed: meropenem in a daily dose of 1.5-3 g and the standard regimen with the use of betalactams and fluoroquinolones in combination with aminoglycosides and/or metronidazole. Patients with recorded diagnosis of nosocomial pneumonia (including the ventilator-associated one) or abdominal infection with the signs of severe sepsis and severity of APACHE II > 14 were enrolled. ⋯ The antibacterial therapy with the use of meropenem was assessed as adequate in 51 out of 56 patients (91.1%), that was 3 times as frequent as with the use of the standard antibacterial therapy (33.9%). The cost-effectiveness coefficient with the use of meropenem was 2.2 times lower vs. the control. Therefore, the empirical therapy of severe nosocomial infections with meropenem proved to be more adequate and from the economic viewpoint more advantageous vs. the standard combined regimens of antibacterial therapy, that was evident from significantly higher clinical and bacteriological efficacy of the treatment and decrease of the terms of the patients hospitalization in intensive care units (on the average by 5 days).
