Enhancing patient safety: detection of in-hospital hazards and effect of training on detection (by training in a low-fidelity simulation Room of Improvement based on hospital-specific CIRS cases).

Importance: Adequate situational awareness in patient care increases patient safety and quality of care. To improve situational awareness, an innovative, low-fidelity simulation method referred to as Room of Improvement, has proven effective in various clinical settings.

Objective: To investigate the impact after 3 months of Room of Improvement training on the ability to detect patient safety hazards during an intensive care unit shift handover, based on critical incident reporting system (CIRS) cases reported in the same hospital.

Oral transmucosal fentanyl citrate analgesia in prehospital trauma care: an observational cohort study.

Background: Pain is one of the major prehospital symptoms in trauma patients and requires prompt management. Recent studies have reported insufficient analgesia after prehospital treatment in up to 43% of trauma patients, leaving significant room for improvement. Good evidence exists for prehospital use of oral transmucosal fentanyl citrate (OTFC) in the military setting.

Risk-Adjusted Mortality Rates as a Quality Proxy Outperform Volume in Surgical Oncology-A New Perspective on Hospital Centralization Using National Population-Based Data.

Purpose: Despite a long-known association between annual hospital volume and outcome, little progress has been made in shifting high-risk surgery to safer hospitals. This study investigates whether the risk-standardized mortality rate (RSMR) could serve as a stronger proxy for surgical quality than volume.

Methods: We included all patients who underwent complex oncologic surgeries in Germany between 2010 and 2018 for any of five major cancer types, splitting the data into training (2010-2015) and validation sets (2016-2018).

Ketamine vs. haloperidol for prevention of cognitive dysfunction and postoperative delirium: A phase IV multicentre randomised placebo-controlled double-blind clinical trial.

Study Objective: Delirium is frequently observed in the postoperative and intensive care unit (ICU) population. Due to the multifactorial origin of delirium and according to international guidelines (e.g.

A preoperative single dose of methadone for moderate-to-severely painful surgery reduces postoperative morphine consumption.

Background: Data from patient questionnaires reveal that the intensity of postoperative pain is widely underestimated. Insufficient pain control may contribute to impaired short- and long-term outcome. Preoperative administration of methadone might potentially improve postoperative pain control due to its long pharmacological half-life.

Background: There is a wide variation of perineural catheter (PNC) colonization rates in the literature. The impact of skin disinfection on PNC colonization and inflammation is not clear. The objective of this prospective, randomized clinical study was to investigate the influence of alcoholic skin disinfection before PNC removal on the detection of bacteria on PNC.

Performance Trends in Master Butterfly Swimmers Competing in the FINA World Championships.

Performance trends in elite butterfly swimmers are well known, but less information is available regarding master butterfly swimmers. We investigated trends in participation, performance and sex differences in 9,606 female and 13,250 male butterfly race times classified into five-year master groups, from 25-29 to 90-94 years, competing in the FINA World Masters Championships between 1986 and 2014.

Differences in age of peak marathon performance between mountain and city marathon running - The ‘Jungfrau Marathon’ in Switzerland.

The age of the best marathon performance has been well investigated for flat city marathon running, but not for mountain marathon running. The aim of this study was to determine the age of the best mountain marathon performance and to compare to results of a flat city marathon. Race times and ages of finishers of a mountain marathon with 1,830 m of altitude change (Jungfrau Marathon, Switzerland) and two flat city marathons (Lausanne Marathon and Zurich Marathon, Switzerland) were analysed using linear, non-linear and mixed-effects regression analyses.

Performance and age of African and non-African runners in World Marathon Majors races 2000-2014.

The age for the fastest marathoners is well investigated, but not the age and nationality of the fastest. We investigated the age of peak marathon performance for the annual top 100 women and men competing in four races of the "World Marathon Majors" (Boston, Berlin, Chicago and New York) and the "Stockholm Marathon" between 2000 and 2014 using mixed-effects regression analyses and one-way ANOVA. Race times of Ethiopian men decreased to 2:14 h:min, but remained unchanged for Kenyan (2:14 h:min), Moroccan (2:15 h:min) and South African (2:18 h:min) men.

Do women reduce the gap to men in ultra-marathon running?

The aim of the present study was to examine sex differences across years in performance of runners in ultra-marathons lasting from 6 h to 10 days (i.e. 6, 12, 24, 48, 72, 144, and 240 h).

Increased participation and improved performance in age group backstroke master swimmers from 25-29 to 100-104 years at the FINA World Masters Championships from 1986 to 2014.

Participation and performance trends in age group athletes have been investigated for different sport disciplines, but not for master swimmers. The knowledge on this topic is still missing for a particular stroke such as backstroke. Changes in participation and performance of male and female age group backstroke swimmers (≥25 years) competing in 50, 100 and 200 m pool swimming at the FINA World Masters Championships held between 1986 and 2014 were investigated using mixed-effects regression analyses.

[Ironman Triathlon].

Every year, thousands of triathletes try to qualify for the «Ironman Hawaii» (3,8 km swimming, 180 km cycling and 42,195 km running), the World Championship of long-distance triathletes. In this overview, we present the recent findings in literature with the most important variables with an influence on Ironman triathlon performance. The most important performance-influencing factors for a fast Ironman race time for both women and men are a large training volume and a high intensity in training, a large volume being more important than a high intensity, a low percentage of body fat, an ideal age of 30–35 years, a fast personal best in the Olympic distance triathlon (1,5 km swimming, 40 km cycling and 10 km running), a fast personal best in marathon running and origin from the United States of America.
