- AIMS AND OBJECTIVES: Validation of the Swedish version of the Nursing Delirium Screening Scale as a screening tool for nurses to use to detect postoperative delirium in patients 70 years and older undergoing cardiac surgery.BACKGROUND: Delirium is common among old patients after cardiac surgery. Underdiagnosis and poor documentation of postoperative delirium is problematic, and nurses often misread the signs.DESIGN: A prospective observational study.METHODS: Patients (n = 142) scheduled for cardiac surgery were assessed three times daily by the nursing staff using the Nursing Delirium Screening Scale. Nursing Delirium Screening Scale was compared with the Mini Mental State Examination and the Organic Brains Syndrome Scale, evaluated day one and day four postoperatively. Delirium was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders - DSM-IV-TR criteria.RESULTS: A larger proportion of patients were diagnosed with delirium according to the Mini Mental State Examination and Organic Brains Syndrome Scale compared with the Nursing Delirium Screening Scale, both on day one and day four. The Nursing Delirium Screening Scale protocol identified the majority of hyperactive and mixed delirium patients, whereas several with hypoactive delirium were unrecognised.CONCLUSIONS: The Swedish version of the Nursing Delirium Screening Scale was easily incorporated into clinical care and showed high sensitivity in detecting hyperactive symptoms of delirium. However, in the routine use by nurses, the Nursing Delirium Screening Scale had low sensitivity in detecting hypoactive delirium, the most prevalent form of delirium after cardiac surgery. Nursing Delirium Screening Scale probably has to be combined with cognitive testing to detect hypoactive delirium.RELEVANCE TO CLINICAL PRACTICE: Nurses play a key role in detecting delirium. The Nursing Delirium Screening Scale was easy incorporated instrument for clinical practice and identified the majority of hyperactive and mixed delirium, but several of the patients with hypoactive delirium were unrecognised. Training of assessment and cognitive testing seems to be necessary to detect hypoactive delirium.

Journal article (peer-reviewed)abstract
- Background: Behavioral and psychological symptoms are common among cognitively impaired individuals and psychotropic drugs are widely used for their treatment. The aim of this study was to describe the prevalence and associated factors of psychotropic and anti-dementia drug use among old people with cognitive impairment living in geriatric care settings. Methods: The study comprised 2,019 cognitively impaired people living in geriatric care units in the county of Västerbotten, Sweden. Data concerning psychotropic and anti-dementia drug use, function in activities of daily living, cognitive function, and prevalence of behavioral and psychological symptoms were collected, using the Multi-Dimensional Dementia Assessment Scale. Results: Of the study population, 1,442 individuals (71%) were prescribed at least one psychotropic drug (antidepressants (49%), anxiolytics, hypnotics, and sedatives (36%), antipsychotics (25%)). Furthermore, 363 individuals (18%) received anti-dementia drugs. Associations between various behavioral and psychological symptoms were found for all psychotropic drug classes and anti-dementia drugs. Verbally disruptive/attention-seeking behavior was associated with all psychotropic drugs. Use of antipsychotics was associated with several behavioral and psychological symptoms, including aggressive behavior. Conclusion: The associations between behavioral and psychological symptoms and psychotropic drug use found in this study indicate that these drugs are prescribed to treat behavioral and psychological symptoms among cognitively impaired individuals despite limited evidence of their efficacy. Given the significant risk of adverse effects among old people with cognitive impairment, it is important to ensure that any medication used is both appropriate and safe.

Journal article (peer-reviewed)abstract
- Background Drug-related problems cause suffering for patients and substantial costs. Multi-dose drug dispensing is a service in which patients receive their medication packed in bags with one unit for each dose occasion. The electronic expert support system (EES) is a clinical decision support system that provides alerts if potential drug-related problems are detected among a patients’ current prescriptions, including drug–drug interactions, therapy duplications, high doses, drug-disease interactions, drug gender warnings, and inappropriate drugs and doses for geriatric or pediatric patients. Objective The aim of the study was to explore physicians’ views on the clinical relevance of alerts provided by EES. Furthermore we investigated if physicians performed any changes in drug treatment following the alerts and if there were any differences in perceived relevance and performed changes between different types of alerts and drugs. Setting Two geriatric clinics and three primary care units in Sweden. Method Prescribed medications for patients (n = 254) with multi-dose drug dispensing were analyzed for potential drug-related problems using EES. For each alert, a physician assessed clinical relevance and indicated any intended action. A total of 15 physicians took part in the study. Changes in drug treatment following the alerts were later measured. The relationship between variables was analyzed using Chi square test. Main outcome measure Physicians’ perceived clinical relevance of each alert, and changes in drug treatment following the alerts. ResultsPhysicians perceived 68 % (502/740) of EES alerts as clinically relevant and 11 % of all alerts were followed by a change in drug treatment. Clinical relevance and likelihood to make changes in drug treatment was related to the alert category and substances involved in the alert. Conclusion In most patients with multi-dose drug dispensing, EES detected potential drug-related problems, with the majority of the alerts regarded as clinically relevant and some followed by measurable changes in drug treatment.

Journal article (peer-reviewed)abstract
- Background: Behavioral and psychological symptoms, such as verbal or physical aggression, aberrant motor behaviors, psychotic symptoms, anxiety, depressive symptoms and apathy are common among people with dementia. The aim of the present study was to compare the one-week prevalence of behavioral and psychological symptoms and psychotropic drug treatment among people with cognitive impairment living in institutional care, in two large, comparable samples from 2000 and 2007. Methods: A comparison was made between two cross-sectional samples, collected in 2000 and 2007, comprising 4054 participants with cognitive impairment living in geriatric care units in the county of Västerbotten, Sweden. The Multi-Dimensional Dementia Assessment Scale (MDDAS) was used to assess cognitive impairment and behavioral and psychological symptoms. The use of psychotropic drugs was recorded. Results: Between 2000 and 2007, 15 out of 39 behavioral or psychological symptoms had become less common and no symptoms had become more common, after controlling for demographic changes. Four out of six behaviors within the cluster of aggressive behaviors had declined in prevalence. Patients prescribed anti-dementia drugs increased from 5.1% to 18.0% and antidepressant drug use increased from 43.2% to 49.1%, while anxiolytic, hypnotic, sedative and antipsychotic drug use remained largely unchanged. Conclusion: The prevalence of many behavioral symptoms had declined from 2000 to 2007, and among these changes, the decline in aggressive behaviors probably has the greatest clinical impact.

Journal article (peer-reviewed)abstract
- Depressive disorders are common among the very old, but insufficiently studied. The present study aims to identify risk factors for depressive disorders in very old age.The present study is based on the GERDA project, a population-based cohort study of people aged a parts per thousand yen85 years (n = 567), with 5 years between baseline and follow-up. Factors associated with the development of depressive disorders according to DSM-IV criteria at follow-up were analysed by means of a multivariate logistic regression.At baseline, depressive disorders were present in 32.3 % of the participants. At follow-up, 69 % of those with baseline depressive disorders had died. Of the 49 survivors, 38 still had depressive disorders. Of the participants without depressive disorders at baseline, 25.5 % had developed depressive disorders at follow-up. Baseline factors independently associated with new cases of depressive disorders after 5 years were hypertension, a history of stroke and 15-item Geriatric Depression Scale score at baseline.The present study supports the earlier findings that depressive disorders among the very old are common, chronic and malignant. Mild depressive symptoms as indicated by GDS-15 score and history of stroke or hypertension seem to be important risk factors for incident depressive disorders in very old age.

Journal article (peer-reviewed)abstract
- A few studies indicate that self reported physical activity is associated with the risk of fractures in middle-aged and elderly men. We investigated whether objectively measured physical fitness in young adulthood was associated with the risk of low-energy fractures later in life in men. Aerobic capacity and isometric muscle strength were measured in 435445 Swedish men that conscripted for military service from 1969-1978. Incident fractures were searched in national registers. During a median follow-up period of 35 years (range, 11-41 years), 8 030 subjects sustained at least one fracture, increasing the risk of death 1.8 times (95% CI = 1.6-2.0) during follow up. When comparing men in the lowest and highest decile of physical fitness, the risk of a fracture was 1.8 times higher (95% CI = 1.6-2.1) and that of hip fracture was 2.7 times higher (95% CI = 1.6-4.7). The risk of fracture was also 1.4-1.5 times higher when comparing the extreme deciles of muscle strength (p < 0.001 for all). In a subcohort of 1009 twin pairs, up to 22% of the variation in physical fitness and 27-39% of the variation in muscle strength was attributable to environmental factors unique to one twin, e.g. physical activity. In conclusion, low aerobic capacity and muscle strength in young adulthood are associated with an increased risk of low-energy fractures later in life, while a low-energy fracture is associated with an increased risk of death already in middle-aged men.

- IMPORTANCE: Young-onset dementia (YOD), that is, dementia diagnosed before 65 years of age, has been related to genetic mutations in affected families. The identification of other risk factors could improve the understanding of this heterogeneous group of syndromes.OBJECTIVE: To evaluate risk factors in late adolescence for the development of YOD later in life.DESIGN: We identified the study cohort from the Swedish Military Service Conscription Register from January 1, 1969, through December 31, 1979. Potential risk factors, such as cognitive function and different physical characteristics, were assessed at conscription. We collected other risk factors, including dementia in parents, through national register linkage.PARTICIPANTS: All Swedish men conscripted for mandatory military service (n = 488 484) with a mean age of 18 years.SETTING: Predominantly Swedish men born from January 1, 1950, through December 31, 1960.EXPOSURE: Potential risk factors for dementia based on those found in previous studies, data available, and quality of register data.MAIN OUTCOMES AND MEASURE: All forms of YOD.RESULTS: During a median follow-up of 37 years, 487 men were diagnosed as having YOD at a median age of 54 years. In multivariate Cox regression analysis, significant risk factors (all P < .05) for YOD included alcohol intoxication (hazard ratio, 4.82 [95% CI, 3.83-6.05]); population-attributable risk, 0.28), stroke (2.96 [2.02-4.35]; 0.04), use of antipsychotics (2.75 [2.09-3.60]; 0.12), depression (1.89 [1.53-2.34]; 0.28), father's dementia (1.65 [1.22-2.24]; 0.04), drug intoxication other than alcohol (1.54 [1.06-2.24]; 0.03), low cognitive function at conscription (1.26 per 1-SD decrease [1.14-1.40]; 0.29), low height at conscription (1.16 per 1-SD decrease [1.04-1.29]; 0.16), and high systolic blood pressure at conscription (0.90 per 1-SD decrease [0.82-0.99]; 0.06). The population-attributable risk associated with all 9 risk factors was 68%. Men with at least 2 of these risk factors and in the lowest third of overall cognitive function were found to have a 20-fold increased risk of YOD during follow-up (hazard ratio, 20.38 [95% CI, 13.64-30.44]).CONCLUSIONS AND RELEVANCE: In this nationwide cohort, 9 independent risk factors were identified that accounted for most cases of YOD in men. These risk factors were multiplicative, most were potentially modifiable, and most could be traced to adolescence, suggesting excellent opportunities for early prevention.

Journal article (peer-reviewed)abstract
- IMPORTANCE Observational studies have shown that obesity is a major risk factor for cardiovascular disease and death. The extent of genetic confounding in these associations is unclear. OBJECTIVE To compare the risk of myocardial infarction (MI), type 2 diabetes, and death in monozygotic (MZ) twin pairs discordant for body mass index (BMI). DESIGN, SETTING, AND PARTICIPANTS A cohort of 4046 MZ twin pairs with discordant BMIs (difference >0.01) was identified using the nationwide Swedish twin registry. The study was conducted from March 17, 1998, to January 16, 2003, with follow-up regarding incident outcomes until December 31, 2013. MAIN OUTCOMES AND MEASURES The combined primary end point of death or MI and the secondary end point of incident diabetes were evaluated in heavier compared with leaner twins in a co-twin control analysis using multivariable conditional logistic regression. RESULTS Mean (SD) baseline age for both cohorts was 57.6 (9.5) years (range, 41.9-91.8 years). During a mean follow-up period of 12.4 (2.5) years, 203 MIs (5.0%) and 550 deaths (13.6%) occurred among heavier twins (mean [SD] BMI, 25.9 [3.6] [calculated as weight in kilograms divided by height in meters squared]) compared with 209 MIs (5.2%) and 633 deaths (15.6%) among leaner twins (mean [SD] BMI, 23.9 [3.1]; combined multivariable adjusted odds ratio [OR], 0.75; 95% CI, 0.63-0.91). Even in twin pairs with BMI discordance of 7.0 or more (mean [SE], 9.3 [0.7]), where the heavier twin had a BMI of 30.0 or more (n = 65 pairs), the risk of MI or death was not greater in heavier twins (OR, 0.42; 95% CI, 0.15-1.18). In contrast, in the total cohort of twins, the risk of incident diabetes was greater in heavier twins (OR, 2.14; 95% CI, 1.61-2.84). Finally, increases in BMI since 30 years before baseline were not associated with the later risk of MI or death (OR, 0.97; 95% CI, 0.89-1.05) but were associated with the risk of incident diabetes (OR, 1.13; 95% CI, 1.01-1.26). CONCLUSIONS AND RELEVANCE In MZ twin pairs, higher BMI was not associated with an increased risk of MI or death but was associated with the onset of diabetes. These results may suggest that lifestyle interventions to reduce obesity are more effective in decreasing the risk of diabetes than the risk of cardiovascular disease or death.

Physical restraint use in institutional care of old people in Sweden in 2000 and 2007
- 2012
-
In: International psychogeriatrics. - 1041-6102 .- 1741-203X. ; 24:7, s. 1144-1152

Journal article (peer-reviewed)abstract
- Background: Physical restraint use is common in institutional care for old people and mainly used to prevent falls, despite the fall-preventive effect of physical restraints being questioned in previous research. The aim of the study was to investigate the use of physical restraints in Sweden in 2000 and 2007. Methods: Data were collected from two comparable census surveys conducted in all institutional care units for old people in 2000 (n = 3,669) and 2007 (n = 2,914). Information on residents' characteristics and physical restraint use was collected using the Multi-Dimensional Dementia Assessment Scale (MDDAS). Results: In 2000 16.0% (95% confidence interval (CI) 14.8%-17.2%) of the residents were restrained compared to 18.2% (95% CI 16.8%-19.6%) in 2007 (p = 0.017). Adjusting for residents' characteristics showed that residents in 2007 were more likely to be physically restrained, relative to the residents in 2000 (odds ratio (OR) 1.031, 95% CI 1.005-1.058, p = 0.017). In 2007 the residents had been restrained longer, and a higher proportion were restrained for unknown reasons. Conclusions: Physical restraint use is still common. Moreover, the findings of this study suggest a small increase (OR 1.031) in the prevalence of physical restraint use from 2000 to 2007 adjusted for residents' characteristics.
