N2 - Objective To assess the structures for early and differential diagnosis of dementia in hospitals in Germany. Methods Written questionnaire to all German hospitals. Results 14 % of 1.758 hospitals responded. Of those, 52 % reported to offer a special service for early dementia diagnosis, mostly on an outpatient basis. The applied methods were in agreement with the national guideline for diagnosis and treatment of dementias, including technical diagnostics, such as neuroimaging and cerebrospinal fluid examinations. 46 % of the diagnostic spectrum were dementia. 41 % were either diagnosed as mild cognitive impairment (MCI) or as subjective cognitive decline (SCD). Conclusion Despite mostly insufficient reimbursement, a large proportion of the responding hospitals offer a specialized service, which largely adheres to guideline-based diagnostic procedures. The concepts of at-risk and prodromal stages of dementia seem to be largely established.

Methods: PubMed, PsycINFO, and Cochrane Library databases were searched in August 2018, with no restrictions in language or publication date. Two independent reviewers identified 33 eligible randomized controlled trials (RCTs) conducting a technology-based intervention for informal carers of PWD. Meta-analyses for the outcome measures caregiver depression and caregiver burden were conducted with subgroup analyses according to mode of delivery (telephone, computer/web-based, combined interventions). To assess methodologic quality, the Cochrane risk-of-bias assessment was rated. Results: Meta-analyses revealed a small but significant postintervention effect of technology-based interventions for caregiver depression and caregiver burden. Combined interventions showed the strongest effects. Conclusion: Technology-based interventions have the potential to support informal caregivers of PWD. Because of advantages such as high flexibility and availability, technology-based interventions provide a promising alternative compared with "traditional services," e.g., those for people living in rural areas. More high-quality RCTs for specific caregiver groups are needed.

T1 - Diverging awareness of postoperative delirium and cognitive dysfunction in German Health Care Providers JF - Clinical interventions in agins N2 - Purpose: Postoperative cognitive dysfunction (POCD) appears in up to 30% of patients suffering from postoperative delirium (POD). Both are associated with higher mortality and postoperative complications, prolonged hospital stays, and increased costs. Multi-modal models with pre-admission risk reduction counselling, perioperative monitoring, and training of multidisciplinary patient care providers have been shown to decrease the prevalence of both. The aim of our study is to understand how far those measures are known and implemented in routine care and to detect potential gaps in the current practice regarding risk communication and information flow between involved caregivers for patients at risk for POD/POCD. Patients and Methods: As part of a multicenter study, seven semi-structured focus group (FG) discussions with nurses and physicians from tertiary care hospitals (surgery, anesthesiology, and orthopedics, n=31) and general practitioners (GPs) in private practice (n=7) were performed. Transcribed discussions were analyzed using qualitative content analysis. Results: POD is present above all in the daily work of nurses, whereas physicians do not perceive it as a relevant problem. Physicians report that no regular risk assessment or risk communication was performed prior to elective surgery. Information about POD often gets lost during hand-offs and is not regularly reported in discharge letters. Thus, persisting cognitive dysfunction is often missed. The importance of standardized documentation and continuous education concerning risks, screening, and treatment was emphasized. The often-suggested pre-OP medication adjustment was seen as less important; in contrast, avoiding withdrawal was regarded as far more important. Conclusion: Altogether, it seems that standards and available best practice concepts are rarely implemented. In contrast to physicians, nurses are highly aware of delirium and ask for standardized procedures and more responsibility. Therefore, raising awareness regarding risks, screening tools, and effective preventive measures for POD/POCD seems an urgent goal. Nurses should have a central role in coordination and care of POD to prevent the risk for POCD.

This study included patients aged 65-90 from 1072 primary care practices who were first diagnosed with dementia between 2010 and 2013. Controls were matched (1:1) to cases for age, sex, and type of health insurance. The primary outcome was the diagnosis of hip fracture during the three-year follow-up period. A total of 53,156 dementia patients and 53,156 controls were included. A total of 5.3% of patients and 0.7% of controls displayed hip fracture after three years. Hip fracture occurred more frequently in dementia subjects living in nursing homes than in those living at home (9.2% versus 4.3%). Dementia, residence in nursing homes, and osteoporosis were risk factors for fracture development. Antidementia, antipsychotic, and antidepressant drugs generally had no significant impact on hip fracture risk when prescribed for less than six months. Dementia increased hip fracture risk in German primary care practices.

Methods: We investigated the reliability and validity of the 14-item PSS in a sample of 80 couples, each including one spouse who had been diagnosed with mild to moderate dementia (mean age 75.55, SD = 5.85, 38.7% female) and one spousal caregiver (mean age 73.06, SD = 6.75, 61.3% female). We also examined the factor structure and sensitivity of the scale with regard to gender differences. Results: Exploratory factor analysis of the PSS revealed a two-factor solution for the scale; the first factor reflected general stress while the second factor consisted of items reflecting the perceived ability to cope with stressors. A confirmatory factor analysis verified that the data were a better fit for the two-factor model than a one-factor model. The two factors of the PSS showed good reliability for patients as well as for caregivers ranging between alpha = 0.73 and alpha = 0.82. Perceived stress was significantly positively correlated with depressive symptomatology in both caregivers and patients. Mean PSS scores did not significantly differ between male and female patients nor did they differ between male and female caregivers. Conclusion: The present data indicate that the PSS provides a reliable and valid measure of perceived stress in dementia patients and their caregivers.

This study examines the relationships between ‘own DC’ and ‘perceived partner DC’ with depressive symptoms in couples coping with dementia on individual (actor effects) and cross-person (partner effects) levels. Method: 164 individuals (82 patients with early-stage dementia and their 82 caregiving partners; ND = 82 dyads) participated in this prospective study with measures (DC, depressive symptoms, and dementia severity) taken at baseline and at six months. Each partner evaluated their own and the perceived partner DC. Actor–partner interdependence models were applied to the resulting four independent evaluations. Results: Results differed substantially between patients and caregivers. DC was significantly related to patients’ but not to caregivers’ depressive symptoms, when adjustments were made for individual coping. Perceived partner DC showed a negative association with depressive symptoms in patients, whereas own DC was adversely related for actor as well as for partner effects across individuals. Conclusion: The adverse association between the own DC of the caregiver and the patient on depressive symptoms of the patient might be due to inappropriate efforts or to the loss of autonomy as a care-receiver. DC is important in both patients and caregivers, as shown by the negative association between perceived partner DC and depressive symptoms in the patients, which might inform interventions that target the couple as a whole.

JF - International psychogeriatrics N2 - Background: Given the well-established association between perceived stress and quality of life (QoL) in dementia patients and their partners, our goal was to identify whether relationship quality and dyadic coping would operate as mediators between perceived stress and QoL. Results: We found negative correlations between stress and QoL in both partners (QoL-AD: r = -0.62; p < 0.001; WHO-QOL Overall: r = -0.27; p = 0.02). Spousal caregivers had a significantly lower DCI total score than dementia patients (p < 0.001). Dyadic coping was a significant mediator of the relationship between stress and QoL in spousal caregivers (z = 0.28; p = 0.02), but not in dementia patients. Likewise, relationship quality significantly mediated the relationship between stress and QoL in caregivers only (z = -2.41; p = 0.02). Conclusions: This study identified dyadic coping as a mediator on the relationship between stress and QoL in (caregiving) partners of dementia patients. In patients, however, we found a direct negative effect of stress on QoL. The findings suggest the importance of stress reducing and dyadic interventions for dementia patients and their partners, respectively.

Our aim was to estimate dementia risk factors in German primary care patients. Methods: The case-control study included primary care patients (70-90 years) with first diagnosis of dementia (all-cause) during the index period (01/2010-12/2014) (Disease Analyzer, Germany), and controls without dementia matched (1:1) to cases on the basis of age, sex, type of health insurance, and physician. Practice visit records were used to verify that there had been 10 years of continuous follow-up prior to the index date. Multivariate logistic regression models were fitted with dementia as a dependent variable and the potential predictors. Conclusions: Risk factors for dementia found in this study are consistent with the literature. Nevertheless, the associations between statin, PPI and antihypertensive drug use, and decreased risk of dementia need further investigations.
