To gain insight into which elements of the interpersonal care relationship (IPCR) are perceived as occurring (less) frequently and as (not) disturbing from the perspective of hospitalized older patients. A cross-sectional study in three Belgian hospitals. A convenience sample of patients aged 75years or older admitted to a non-geriatric ward were recruited between May 2017 and April 2019. The Interpersonal Geriatric care relationship (InteGer) tool was used to identify elements of the IPCR and was completed by the researchers through structured patient interviews. The mean total scale score for frequency was 3.74 (SD 1.51) [range 0-12]. On subscale level, the highest mean score was in the accessibility and the lowest mean score in the humanization subscale. Statistically significant differences between the hypothesized and experienced disturbance were observed in 18 of the 30 items. Ten items score in the category 'no action needed' (not occurring, not disturbing), nine items in the category 'remain attentive for patient experiences' (occurring, not disturbing), 10 items in the category 'further analyses or monitoring needed' (not occurring, disturbing) and one item in the category 'urgent action needed' (occurring and disturbing). Participants report mostly positive experiences related to the four subscales of the InteGer, that is, humanization, attentiveness, interest and accessibility. Insights from this study provide important opportunities in the context of care optimization for each category with the main focus on items with high experienced disturbance. The InteGer can be used for monitoring IPCR and formulating action points at ward and hospital level to further improve the IPCR and quality of care.
