- Bipolar disorder has long been associated with increased risks for suicidality; though factors associated with dying by suicide remain obscure. Here, we retrospectively examine the associations between the different phases of bipolar illness and other common comorbidities with death by suicide in the 120 days following each discharge for Swedes first admitted as inpatients for bipolar disorder during the years 2000-2014. Data on admissions and suicide deaths were extracted from the Swedish National Patient Register and the Cause of Death Register, respectively. ICD-10 diagnostic codes were used to define the phases: depressive, manic, mixed, and other; and the comorbidities: specific substance use disorders, attention deficit hyperactivity disorder, and personality disorders. Extended Cox regressions were employed to model the time to death by suicide as a function of the bipolar phases, comorbidities, and other important control variables. Our analysis included 60,643 admissions by 22,402 patients over an observation time of 15,187 person-years. Overall, 213 (35.7%) of all suicides occurred within 120 days of discharge. Upon adjustment and compared to the depressive phases, manic phases were significantly associated with a far lower hazard of dying by suicide (HR 0.34, 95% CI: 0.21–0.56, p < 0.001), though mixed phases were not (HR 0.92, 95% CI: 0.48–1.73, p = 0.957). With regard to comorbidity, only sedative use disorder remained significantly associated with dying by suicide upon adjustment (HR 2.08, 95% CI: 1.41–3.06, p = 0.001). Vigilant monitoring of patients post discharge and of prescription practices are recommended.

- Background: The influence of gender on bipolar disorder is controversial and it is unclear if inpatient care differs between men and women. Here, we investigate for gender differences in the inpatient length of stay for Swedes admitted for bipolar disorder and explore other factors that could explain any observed association. Methods: Admission data were extracted from the Swedish National Patient Register and included all patients first admitted to a psychiatric inpatient unit with a bipolar disorder diagnosis, circa 2005–2014. Patients were then retrospectively followed for subsequent hospitalizations. Diagnostic subtypes were categorized by ICD-10 clusters: depressive, depressive with psychotic features, manic, manic with psychotic features, mixed, and other. Psychotropic therapies preceding the corresponding admissions were attained from the Prescribed Drug Register. Mixed-effects zero-truncated negative binomial regressions were employed to model the length of stay per admission. Results: Analysis included 39,653 admissions by 16,271 inpatients (60.0% women). Overall, when compared to men, women spent 7.5% (95% CI: 4.2–11.0%, p < 0.001) extra days hospitalized per admission. However, upon adjusting for candidate confounders, including the bipolar subtype, and selected comorbidities and psychotropics, the association weakened wherein women then spent 3.7% (95% CI: 0.1–6.9%, p = 0.028) extra days hospitalized per admission. Limitations: The integrity of register data can be variable and the adherence to outpatient dispensed psychotropics could not be validated. Conclusion: Although the influence of gender on the bipolar disorder inpatient length of stay is evident, other factors attenuate and better explain this crude observation.

Tidskriftsartikel (refereegranskat)abstract
- Background: Long-term pharmacological maintenance therapy is often essential among people with bipolar disorder to reduce the need for inpatient care. Sex-specific responses to maintenance therapies are expected but remain largely unknown. Here, we examined for sex-specific associations between common maintenance therapies for bipolar disorder with inpatient rehospitalizations following patients' index discharges during 2006–2014. Methods: Population-based data on maintenance therapies and rehospitalizations were extracted from Swedish national registries. We adopted the within-individual design to compare the time on- vs. off- maintenance therapy for males and females, respectively. Extended stratified Cox proportional hazards regression models were employed to quantify the rate of rehospitalization as a function of common maintenance drugs and other important time-varying control variables. Results: Our primary analysis included 22,681 bipolar disorder rehospitalizations by 6,400 males and 9,588 (60.0%) females over an observation time of 62,813 person-years. The time spent on- vs. off- maintenance lithium, lamotrigine, quetiapine, or olanzapine was statistically significant upon adjustment among either sex for reducing the rate of bipolar rehospitalizations. Adjusted sex-specific statistically significant associations were also observed. Among females, the time on- (vs. off-) long-acting injectable risperidone reduced the rate of bipolar rehospitalizations by 73% (56–84%), carbamazepine by 44% (18–62%), aripiprazole by 29% (13–42%), and valproate by 23% (11–33%); whereas among males, ziprasidone by 65% (41–79%). Conclusion: The effectiveness of most maintenance therapies is generally comparable and uniform among both males and females. Despite some statistically significant sex-specific associations, estimates for each drug were fairly consistent between sexes.
