A growing number of organisations in residential care for older people are working towards safe and inclusive environments for LGBT residents. In the Netherlands, these efforts are supported by an LGBT inclusion scheme called ‘Pink Passkey’. Drawing on critical organisational diversity studies, the paper understands inclusion as ‘accomplished’ in interactions across difference, and as always inherently partial (i.e. exclusion-producing). Qualitative methods are used to study the implementation process of the Pink Passkey in two nursing homes during one year. In sum, the paper contributes evidence of positive change associated with the use of the Pink Passkey as an inclusion scheme characterised by a long-term, open-ended and comprehensive approach. Compared to fixed-term projects and stand-alone measures described in previous LGBT ageing literature, an inclusion scheme helps to gain sustained attention to sexual and gender diversity (despite gaps in the implementation process), to normalise it more and to overcome opposition (though this does not disappear). The inclusion accomplished is, indeed, partial: bisexual, transgender and other gender non-conforming identities are less represented than gay and lesbian identities. Also, there is an emphasis on residents' agency to disclose LGBT identities and preferences, which excludes involuntary same-sex sexual expressions caused by disinhibited behaviour. The paper ends by suggesting disinhibited behaviour in older LGBT adults as an issue of interest to the wider literature on LGBT ageing, given the increasing prevalence of dementia and Parkinson's disease. Here, the role of care professionals who are able to understand and respond to bodily cues that echo struggles with otherness merits further consideration.
