Background. Comprehensive geriatric assessment has been advocated as an effective way to first identify multidimensional needs and second to establish priorities for organizing an individual health care plan for community-dwelling elderly. This paper reports on the perception of an internationally evaluated assessment system for use in community care programmes, the Minimal Data Set-Home Care (MDS-HC©), by a group of experienced GP trainers. Objective. The primary study aim was to determine the perception of a standardized home care assessment system (MDS-HC©) by GP trainers in terms of acceptability, perceived clinical relevance, care planning empowerment and valorization of the GP. Methods. Sixty-five first-year GP trainees were educated about the MDS-HC© and the use of a first version of an electronic interface. Each trainee included two elderly patients, based on strict inclusion criteria. Prior to the assessment, GP trainers and trainees were invited to complete together a basic medical record on the basis of their knowledge of the included patients. Next, the collected data, covering the multiple domains by MDS-HC©, were introduced in the electronic interface by the trainee. Based on the collected data for each patient, a series of clinical assessment protocols (CAP's) were generated. Afterwards, these CAP's were critically discussed with the trainer. To investigate how the application of the MDS-HC© was perceived, a 21 Likert-type item scale was drawn up based on four dimensions regarding the tool. Results. The perception questionnaire had a good internal consistency (Cronbach's alpha 0.93). The first version of the electronic interface was considered not ‘user-friendly’ enough and the introduction of data time-consuming. The perception of the GP's about the overall clinical relevance of the MDS-HC© was found to have little added value for the GP in the establishment of a personal management plan. Conclusions. Many developments in health care result in an increasing demand for a standardized home care ...
