Reducing psychotropic pharmacotherapy in patients with severe mental illness: a cluster-randomized controlled intervention study.

BACKGROUND: Many patients with mental illness receive psychotropic medicine in high dosages and from more than one drug. One of the consequences of this practice is obesity, which is a contributing factor to increased physical morbidity and premature death. METHODS: Our study was a cluster-randomized intervention study involving 6 facilities and 174 patients diagnosed with severe mental illnesses (73% schizophrenia). The intervention period was 12 months and consisted of teaching sessions with the staff and evaluating the patients' intake of psychotropic medication. At index, 44% met criteria for obesity and 76% met criteria for overweight. Waist circumferences were 108 cm for men and 108 cm for women. Olanzapine, clozapine and quetiapine were the most common prescribed antipsychotics. Mean values of daily doses of antipsychotic were 2.5. RESULTS: The intervention showed no significant differences between the intervention and control group regarding psychotropic treatment. At follow up, independent of intervention, patients receiving antipsychotic polypharmacy had a larger waist circumference compared with patients receiving antipsychotic monotherapy of 9.8 cm (1.5-18.1) (p = 0.028). DISCUSSION AND CONCLUSION: We found both a high prevalence of obesity and that the patients received treatment with antipsychotic polypharmaceutics in high dosages. Active awareness did not change practice and we must think of other ways to restrict treatment with psychotropics in this group of patients.

Risk factors for conversion from unipolar psychotic depression to bipolar disorder.

OBJECTIVES: Patients with unipolar psychotic depression (PD) are at high risk of developing bipolar disorder (BD). This conversion has important implications for the choice of treatment. This study, therefore, aimed to identify risk factors associated with diagnostic conversion from PD to BD. METHODS: We conducted a population-based, historical prospective cohort study by merging data from Danish registers. Patients assigned an ICD-10 diagnosis of PD between 1 January 1995 and 31 December 2007 were identified in the Danish Central Psychiatric Research Register and were followed until the development of BD, death, loss to follow-up, or 31 December 2007. Potential risk factors for conversion to BD, also defined through various Danish registers, were tested in multiple logistic regression analyses with risk expressed as adjusted odds ratios (AOR). RESULTS: We identified 8,588 patients with PD, of whom 609 (7.1%) developed BD during follow-up. The following characteristics were significantly associated with diagnostic conversion from PD to BD: early onset of PD [AOR = 0.99 (per year of increasing age), p = 0.044], recurrent depression [AOR = 1.02 (per episode), p = 0.036], living alone (AOR = 1.29, p = 0.007), receiving a disability pension (AOR = 1.55, p < 0.001), and the highest educational level being a technical education (AOR = 1.55, p < 0.001), short-cycle higher education (AOR = 2.65, p < 0.001), or medium-cycle higher education (AOR = 1.75, p < 0.001). CONCLUSIONS: Diagnostic conversion to BD was prevalent among patients with PD. The following characteristics were significantly associated with this conversion: early onset of PD, recurrent depression, living alone, receiving a disability pension, and the highest educational level being a technical education, short-cycle higher education, or medium-cycle higher education.

Systematic suicide risk assessment for patients with schizophrenia: a national population-based study.

OBJECTIVES: Systematic suicide risk assessment is recommended for patients with schizophrenia; however, little is known about the implementation of suicide risk assessment in routine clinical practice. The study aimed to determine the use of systematic suicide risk assessment at discharge and predictors of suicide attempt among hospitalized patients with schizophrenia in Denmark. METHODS: A one-year follow-up study was conducted of 9,745 patients with schizophrenia who were discharged from psychiatric wards and registered in a national population-based schizophrenia registry between 2005 and 2009. RESULTS: The proportion of patients receiving suicide risk assessment at discharge from a psychiatric ward increased from 72% (95% confidence interval [CI]=71%-74%) in 2005, when the national monitoring began, to 89% (CI=89%-90%) in 2009. Within one year after discharge, 1% of all registered patients had died by suicide and 8% had attempted suicide. One out of three patients who died by suicide had no documented suicide risk assessment before discharge. CONCLUSIONS: The use of systematic suicide risk assessment at discharge among patients with schizophrenia increased in Denmark between 2005 and 2009, in accordance with recommendations in national clinical guidelines and monitoring in a national clinical registry. Additional efforts are warranted to ensure a lower risk of suicidal behavior after hospital discharge.

Increasing mortality gap for patients diagnosed with schizophrenia over the last three decades--a Danish nationwide study from 1980 to 2010.

OBJECTIVE: The objective of this study is to describe secular trends in the average age of death in patients with schizophrenia and to compare these with the general population. METHODS: This is a longitudinal linkage study from 1 January 1980 to 31 December 2010 using the Danish Psychiatric Research Register and the Danish Cause of Death Register. Data were analyzed using descriptive statistics and survival analysis. RESULTS: The average age of death in the schizophrenia population (62.2 years; 95% CI, 61.9-62.5) was lower compared to the general population (73.4 years; 95% CI, 73.4-73.4), P<0.001. In the general population we found, for men, an average increase in the age of death of 0.28 years (95% CI, 0.27-0.28) per calendar year, and for women an increase in age of death of 0.31 years (95% CI, 0.31-0.32) per calendar year (both P<0.001). In contrast, age of death decreased in the schizophrenia population: the change in average age of death for males was 0.04 years (95% CI, -0.09 to 0.00) per calendar year (P<0.05), and the comparable estimate for females was -0.05 years (95% CI, -0.09 to 0.01) per calendar year (P<0.05). A similar pattern existed after acts of self-harm as cause of death were excluded from the analyses. Patients diagnosed with schizophrenia had an increased mortality rate compared with the general population (hazard ratio, 2.05; 95% CI, 2.01-2.09). CONCLUSIONS: On average, patients with schizophrenia die younger than the general population, independent of intentional self-harm as cause of death.

Mortality following treatment for cannabis use disorders: predictors and causes.

The aim of the study was to determine excess mortality associated with cannabis use disorders. Individuals entering treatment for cannabis use disorders were followed by use of Danish registers and standardized mortality ratios (SMRs) estimated. Predictors of different causes of death were determined. A total of 6445 individuals were included and 142 deaths recorded during 26,584 person-years of follow-up. Mortality was predicted by age, comorbid use of opioids, and lifetime injection drug use. For different causes of death the SMRs were: accidents: 8.2 (95% CI 6.3-10.5), suicide: 5.3 (95% CI 3.3-7.9), homicide/violence: 3.8 (95% CI 1.5-7.9), and natural causes: 2.8 (95% CI 2.0-3.7). Following exclusion of those with secondary use of opioids, cocaine, amphetamine, or injection drug use, SMRs for all causes of death remained significantly elevated except for homicide/violence. The study underlines the need to address mortality risk associated with cannabis use disorders.
