Previous studies report that individuals diagnosed with borderline personality disorder have been met by negative attitudes from healthcare professionals and their care needs have often been neglected during hospitalizations. When symptoms of emotional instability are combined with self-harm, the resulting crisis often becomes difficult to handle for patients and healthcare professionals. To meet their care needs during these crises, an intervention called 'brief admission' (BA) has been developed. The purpose of BA is to provide a timeout, in situations of increased stress and threat, in order to foster self-management in a safe environment. In the present study, we explored the following research questions: What are patients' experiences with BA? What do patients consider to be the key components of BA? What improvements are considered relevant by patients? A qualitative design was employed, and 15 patients (13 females, 2 males; mean age 38.5 ± 12.9, range 20-67 years) were interviewed using a semi-structured interview guide. Thematic analyses were performed, which yielded four themes related to the patients' experiences: 'a timeout when life is tough', 'it is comforting to know that help exists', 'encouraged to take personal responsibility', and 'it is helpful to see the problems from a different perspective'. Four themes also described the key components: 'a clear treatment plan', 'a smooth admission procedure', 'a friendly and welcoming approach from the staff', and 'daily conversations'. Lastly, three themes described areas for improvements: 'feeling guilty about seeking BA', 'room occupancy issues', and 'differences in staff's competence'. Collectively, the findings indicate that BA constructively supports patients with emotional instability and self-harm during a period of crisis.
