Methodology

On the day of the study, a participating researcher (physician or resident) should to include patients for the study. These can be patients on regular nursing units of all specialties. Prior verbal consent should be obtained from the patient for participation in the study and this should be noted in the patient status. After obtaining consent, the questionnaire is given to the patient. This can be completed by the patient himself, if necessary with the support of the researcher. This takes about 10 minutes. The questionnaires should be collected back from the patients afterwards. The researchers complete the enclosed case-report form. This can be done right at the patient's bedside.
