The Austrian Institute for Health Technology Assessment (AIHTA) has investigated which key factors are essential in the planning, design, implementation and operation of so-called dementia quality registries. Finally, the AIHTA report formulates „good practice strategies“ for handling these registries by decision-makers in the health sector. Key findings concern data management, governance and reporting structures, data protection and the nature of quality indicators. An important conclusion of the study is that various interdisciplinary aspects from organisational, evaluation and outcome research must be taken into account when setting up and operating a dementia quality registry.
