Palliative care aims at improving the patient’s quality of life. The assessment of this quality of life (QoL) is crucial for the evaluation of palliative care outcome. Many patients require hospital admissions for symptom control during their cancer journey and most of them die in hospitals, although they would like to stay at home until the end of their lives. In 1986, the European Organization for Research and Treatment (EORTC) initiated a research programme to develop an integrated, modular approach for evaluating the quality of life of patients participating in international clinical trials. This questionnaire measures cancer patients’ physical, psychological and social functions and was used in a wide range of clinical cancer trials with large numbers of research groups and also in various other non-trial studies. The aim of this study was to evaluate the psychometric properties, especially the reliability, validity and applicability of the EORTC QLQ-C30 in a German sample of terminally ill cancer patients receiving palliative care in different settings. The questionnaire was well accepted in the present patient population. Scale reliability was good (pre-treatment 0.80) especially for the functional scale. The results support the reliability and validity of the QLQ-C30 (version 3.0) as a measure of the health-related quality of life in German cancer patients receiving palliative care treatment.

When conducting prevalence surveys pressure ulcers were found in participants clearly identified not to be at risk. This article determines and analyses persons in German hospitals and nursing homes who suffer from pressure ulcers but are not at risk. In the years 2002, 2003 and 2004 there were 7,097 nursing home residents and 23,966 hospital patients examined in annual pressure ulcer prevalence surveys. A risk assessment according to the Braden Scale was performed for each participant on the day of the survey. “Not at risk” participants were defined by Braden score cut-off > 20 points. There were 440 of 3,012 (14.6%) persons with pressure ulcer who were considered not to be at risk. In hospitals, 16.1% of all patients with pressure ulcers were not at risk, in nursing homes it was 8.2%. A high variance between medical specialties and individual institutions was found in the number of those not at risk but with pressure ulcer. In the group not at risk, persons with and without a pressure ulcer differed regarding activity and friction and shear in nursing homes. In hospitals those persons differed regarding age and all single items of the Braden scale apart from sensory perception. Pressure ulcers that are more severe, located at the hip or lower back or the origin of which is unknown are more likely to be considered to be at risk by the Braden risk assessment tool. The results may indicate insufficient abilities of the Braden scale for certain kind of pressure ulcer wounds.

Pressure ulcers and falls are frequent adverse events with negative impacts for hospital patients. Guidelines recommend risk assessment as the first step in prevention. Care dependency correlates with falls and pressure ulcers and the Care Dependency Scale showed a diagnostic validity comparable to that of specific risk assessment tools. The aim of this study was to establish a simple and valid screening index for the risk of falls and pressure ulcers in hospitals by using the Care Dependency Scale and to evaluate this index within two validation samples from different countries. Quantitative, cross-sectional data from two German surveys and one Dutch survey were analysed. A total of 305 Dutch and German hospitals with 21,880 patients took part. The diagnostic validity of the Care Dependency Scale was evaluated by computing receiver operator characteristics curves, the areas under the curves, sensitivity, specificity and positive and negative predictive values.The Scale demonstrated a good diagnostic validity for pressure ulcer risk screening in Dutch and German hospitals. The diagnostic validity regarding the risk for falls was satisfying in Germany and moderate in the Netherlands. Using the Care Dependency Scale for risk screening could reduce the necessity of further assessment by more than a half.
