Chronic wounds have a major socioeconomic impact due to their frequency, chronicity, and societal costs. Patients experience substantial quality of life (QoL) impairments. The use of questionnaires for a continuous assessment of QoL and resulting interventions to improve the situation of the individual are an important cornerstone of a guideline-based wound care. The aim of this study was to investigate the validity of the Wound-QoL questionnaire. Patients with chronic wounds from two different centers were included in the prospective study. All patients completed the Wound-QoL and two other QoL questionnaires (European Quality of Life-5 Dimensions, EQ-5D, and Freiburg Life Quality Assessment for wounds, FLQA-wk) at baseline and at two more time points (4 and 8 weeks, respectively). Wound status was defined with an anchor question. Two hundred and twenty-seven patients (48.5% women) participated in the study. Mean age was 66.9 years (range 17-96, median 69.5). Indications were venous leg ulcers (40.1%), pyoderma gangraenosum (14.1%), diabetic or ischemic foot ulcers (5.3%), pressure ulcers (2.6%), and other etiologies (30.0%). The Wound-QoL showed good internal consistency, with high Cronbach's alpha in all the subscales and in the global scale in all time points (>0.8). Convergent validity was satisfactory since there were significantly (p ≤ 0.001) good correlations with the EQ-5D (range = 0.5-0.7) and FLQA-wk global score (r > 0.8) at every time point. Responsiveness was high, too. The Wound-QoL is a simple, valid tool for the longitudinal assessment of QoL in patients with chronic wounds. This questionnaire is suitable for use in clinical trials, quality of care studies and clinical routine.

BackgroundCommunication and information in order to reduce anxiety in the intensive care unit (ICU) has been described as area needing improvement. Therefore, the aim of this trial was to evaluate whether a structured information program that intensifies information given in standard care process reduces anxiety in ICU patients.MethodsMulticenter, two-armed, non-blinded, parallel-group randomized controlled trial in hospitals in the cities of Marburg, Halle, and Stuttgart (Germany). The trial was performed in cardiac surgery, general surgery, and internal medicine ICUs. Two-hundred and eleven elective and non-elective ICU patients were enrolled in the study (intervention group, n = 104; control group, n = 107). The experimental intervention comprised a single episode of structured oral information that was given in addition to standard care and covered two main parts: (1) A more standardized part about predefined ICU specific aspects – mainly procedural, sensory and coping information, and (2) an individualized part about fears and questions of the patient. The control group received a non-specific episodic conversation of similar length additional to standard care. Both conversations took place at the beginning of the ICU stay and lasted 10–15 minutes. Study nurses administered both interventions. The primary outcome ICU-related anxiety (CINT-Score, 0–100 pts., higher scores indicate higher anxiety) was assessed after admission to a regular ward.ResultsThe primary outcome could be measured in 82 intervention group participants and 90 control group participants resulting in mean values of 20.4 (SD 14.4) compared to 20.8 (SD 14.7) and a mean difference of −0.2 (CI 95% -4.5 to 4.1).ConclusionsA structured information intervention additional to standard care during ICU stay had no demonstrated additional benefit compared to an unspecific communication of similar duration. Reduction of anxiety in ICU patients will probably require more continuous approaches to information giving and communication.Trial registrationClinicalTrials.gov NCT00764933.

The extended use of breathing circuits for 48 and 72 h does not increase significantly the risk of contamination, provided that HME filters are changed separately for every patient.

BackgroundAccording to current evidence and psychological theorizing proper information giving seems to be a promising way to reduce patient anxiety. In the case of surgical patients, admission to the intensive care unit (ICU) is strongly associated with uncertainty, unpredictability and anxiety for the patient. Thus, ICU specific information could have a high clinical impact. This study investigates the potential benefits of a specifically designed ICU-related information program for patients who undergo elective cardiac, abdominal or thoracic surgery and are scheduled for ICU stay.Methods/DesignThe trial is designed as a prospective randomized controlled trial including an intervention and a control group. The control group receives the standard preparation currently conducted by surgeons and anesthetists. The intervention group additionally receives a standardized information program with specific procedural, sensory and coping information about the ICU.A measurable clinical relevant difference regarding anxiety will be expected after discharge from ICU. Power calculation (α = 0.05; β = 0.20; Δ = 8.50 score points) resulted in a required sample size of N = 120 cardiac surgical patients (n = 60 vs. n = 60). Furthermore, N = 20 abdominal or thoracic surgical patients will be recruited (n = 10 vs. n = 10) to gain insight to a possible generalization to other patient groups.Additionally the moderating effect of specific patient attributes (need for cognition, high trait anxiety) will be investigated to identify certain patient groups which benefit most.DiscussionThe proposed study promises to strengthen evidence on effects of a specific, concise information program that addresses the information needs of patients scheduled for ICU stay.

The improvement of surgical skills of trainees in Germany often occurs solely in the operating room. In recent years, several countries have established surgical skills labs as an essential part of surgical education, with the goal of improving and refining surgical skills before clinical application. Several years ago, training units were established by the industry wherein the curricula focused on products of the respective company. Selected training courses are still offered in a few clinics. Presently, laboratories which train the surgical skills of novices in an individually adapted form are lacking. A surgical skills lab with a comprehensive curriculum of training courses was introduced at the University Hospital of Marburg in 2005. The present article describes the development and introduction of such facilities. The authors are convinced that surgical skills labs will become increasingly important in German surgical education for improving patient safety in the operating room.
