About this study
The current study aims to evaluate the impact of long (>5 days) and/or compulsory psychiatric inpatient care on subsequent healthcare utilization for self-harm and suicide in people with borderline personality disorder, a condition characterized by frequent self-harm.
The basis for this study is the diversity of clinical practices across Swedish regions. By categorizing clinics based on their practices with respect to long and/or compulsory psychiatric inpatient care, it is possible to explore the impact of these practices on subsequent somatic and psychiatric healthcare, including emergency care due to self-harm as well as on completed suicides.

All psychiatric clinics across Sweden authorized to administer compulsory care for adults, totalling 78 clinics will be included. Each clinic per specific calendar year will represent one participant, identified by the clinic's name and the respective year (e.g., Umeå2010, Linköping2013, Malmö2022).
Data collection will involve the utilization of the national registers to capture outcome measures and account for confounding factors. The participants will be ranked based on a composite variable, which includes the average number of days spent in inpatient compulsory care and other psychiatric inpatient care exceeding 5 days, among individuals diagnosed with BPD. The top quartile of participants will be compared with the bottom quartile.
- Being tested
- High degree of long (>5 days) and/or compulsory psychiatric inpatient care

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of healthcare visits due to self-harm
Number of healthcare visits due to self-harm in specialized inpatient or outpatient care, as defined in the NPR (X60-X84; Intentional self-harm) divided by the number of individuals diagnosed with BPD per clinic and calendar year.
Measured: 1 year
Number of deaths by suicide
Number of deaths by suicide (X60-X84; Intentional self-harm or Y10-34; Events of undetermined intent) in individuals diagnosed with BPD divided by the number of individuals diagnosed with BPD per clinic and calendar year.
Measured: 1 year
Number of deaths by suicide within 30 days after discharge
Number of deaths by suicide (X60-X84; Intentional self-harm or Y10-34; Events of undetermined intent) within 30 days after discharge, in individuals diagnosed with BPD divided by the number of individuals diagnosed with BPD, per clinic and calendar year
Measured: 1 year
Secondary outcomes (3)
Number of days between admissions to psychiatric inpatient care
Number of days between admissions to psychiatric inpatient care for people diagnosed with BPD divided by the number of individuals diagnosed with BPD per clinic and calendar year.
Measured: 1 year
Number of days between death by suicide and discharge
Number of days between death by suicide (X60-X84; Intentional self-harm or Y10-34; Events of undetermined intent) and discharge in individuals diagnosed with BPD. For this variable, death by suicide during inpatient admission will be labelled 0.
Measured: 1 year
Number of days in somatic (non-psychiatric) inpatient care after self-harm
Number of days in somatic (non-psychiatric) inpatient care after self-harm (X60-X84; Intentional self-harm) divided by the number of individuals diagnosed with BPD per clinic and calendar year.
Measured: 1 year
