Implementation Study of Dementia Guidelines in Primary Care

Background Early diagnosis of dementia benefits both patient and caregiver. Nevertheless, dementia in primary care is currently under-diagnosed in developed countries. In several countries educational interventions were developed to improve dementia diagnosis and management in primary care. Some of these interventions were successful in increasing the number of dementia diagnoses and in changing attitudes and knowledge of health care staff. However, none of these interventions focussed on collaboration between GPs and nurses in dementia care. We developed a Dementia Training Program (DTP) aimed at stimulating collaboration in dementia primary care. We expect it to increase the number of cognitive assessments and dementia diagnoses, as well as to improve attitudes and knowledge of GPs and nurses.

Methods/Design The DTP is a complex educational intervention and consists of 2 workshops, a coaching program, and case-based consultations either face-to-face or by phone or e-mail, access to an internet forum, and a Computerized Clinical Decision Support System on dementia diagnostics and management. 100 duos of GPs and nurses will be recruited, from which 2/3 will be allocated to the intervention group and 1/3 to the control group. The effects of implementation of the DTP will be studied in an assessor blinded cluster-randomised controlled trial. Primary outcomes are the number of cognitive assessments and dementia diagnosis in a period of 9 months, starting after workshop participation of the duos. Secondary outcomes are measured on GP and nurse level: rate of adherence to national guidelines for dementia diagnosis, attitude, confidence and knowledge regarding dementia diagnosis and management; on patient level: number of emergency calls, visits and consultations and patient satisfaction; and on caregiver level: informal caregiver burden and satisfaction. Data will be collected from GPs' electronic medical dossiers, self registration forms and questionnaires. Statistical analysis will be performed by using MANOVA-method. Also, exploratory analyses will be performed, in order to gain insight into barriers and facilitators for implementation and the causal relations between the rate of success of the intervention components and the outcomes.
