Three quarters of stays in psychiatric services for adults in PH last less than 3 months. Around 14.4% of the stays in the PH last less than one week. In the psychiatric services for adults in PDGH, almost 80% of stays last less than one month. One third of the stays even last less than one week. We can also observe that in PH, few stays end on the same day, while this happens more regularly in the PDGH.
Duration of stay in psychiatric services for adults in PH and PDGH
The average number of occupant days per year in a PDGH is significantly lower than in a PH. This is due to the acute treatment of patients that takes priority in a PDGH. In addition, the average number of occupant days per year remains about the same over the years, while in the PH it is shortened by an average of 20 days (26%) compared to 2005.
Evolution of the number of hospital stays
in psychiatric services for adults in PH and PDGH by age
 The average number of occupant days was calculated as the total number of occupant days in relation to the number of hospitalisations in a given year. As a result, this does not relate to the average duration of stay as the number of occupant days in a previous year was not taken into account. For this calculation, both partial and residential stays were taken into account.
