OBJECTIVE	The aim of study was to evaluate setting-specific quality indicators ( QIs ) for shared-housing arrangements ( SHA ) regarding effects of a guided quality development process on resident 's quality of life ( QoL ) .
BACKGROUND	SHA are a specific German kind of small-scale living facilities for care-dependent persons with dementia .
BACKGROUND	SHA are disconnected from residential facilities and served by community care services .
METHODS	In a longitudinal cluster-randomised design 104 residents of 34 SHA were surveyed for 1 year ; the intervention group took part in a quality development process .
METHODS	QIs , physical and psychological health outcomes including QoL were surveyed .
RESULTS	During the 1 year follow-up , analyses show a positive trend regarding QI-outcomes in the intervention group , but no statistically significant differences could be proved regarding QoL .
CONCLUSIONS	Setting-sensitive QIs are absolutely essential to measure quality of care in multi-professional settings like SHA .
CONCLUSIONS	Further research as well as longer study intervals is essential .
