    Prevalences and Indications of Psychotropic Drug Prescriptions in Nursing Home Residents with Korsakoff Syndrome

    by Ineke J. Gerridzen, Els Doejaaren, Ruth B. Veenhuizen, Cees M. P. M. Hertogh, Karlijn J. Joling

    Psychotropic drugs (PD) are often prescribed to nursing home residents with Korsakoff syndrome (KS). It is unknown whether these drugs are prescribed correctly or whether they are prescribed off-label, for example, to treat behavioral symptoms. To get more insight into PD prescriptions, a descriptive study was performed. The type, category and indications of PD prescriptions of 285 participants were analyzed using medication charts and questionnaires. Behavioral symptoms were investigated with the Neuropsychiatric Inventory-Questionnaire. The results showed that atypical antipsychotics (57.1%) were prescribed more frequently than typical antipsychotics (49.3%). Of the antidepressants, selective serotonin/norepinephrine reuptake inhibitors (63.1%) were most frequently prescribed, followed by tricyclic antidepressants (23.4%). Of the benzodiazepines, anxiolytics (85.7%) were more prescribed than hypnotics (24.5%). Besides psychiatric disorders, PD were also prescribed to treat behavioral symptoms varying from 29.9% (antipsycho-tics) to 26.3% (benzodiazepines) and 9.3% (antidepressants). Furthermore, prescriptions were high if behavioral symptoms were present. To conclude, PD are often prescribed to residents with KS for an unapproved indication, namely behavioral symptoms. Additional research is needed to obtain further insight into the current prescribing culture and the effectiveness of PD. The insights thus obtained may, ultimately, contribute to the appropriate prescription of PD for people with KS.

    Factors Associated with ADL Dependence in Nursing Home Residents with Korsakoff’s Syndrome and Other Alcohol-Related Disorders: An Explorative Cross-Sectional Study

    by Eline S. Böhner, Bea Spek, Karlijn J. Joling, Yvonne Zwaagstra, Ineke J. Gerridzen

    Difficulties in performing activities of daily living (ADL) are common in patients with Korsakoff‘s syndrome (KS). The aim of this study was to identify factors associated with ADL dependence in nursing home residents with KS. This exploratory, cross-sectional study included 281 residents with KS from 9 specialized nursing homes in the Netherlands. We examined demographic, cognitive, somatic, and (neuro)psychiatric characteristics. ADL dependence was assessed with the Inter-RAI ADL Hierarchy Scale. Multivariable logistic regression analyses were used to identify factors associated with ADL dependence. Cognitive impairment (odds ratio [OR] = 7.46; 95% confidence interval [CI] = 2.10–30.5), female gender (OR = 3.23; CI, 1.21–8.78), staying in a nursing home for ≥5 years (OR = 3.12; CI, 1.24–8.33), and impaired awareness (OR = 4.25; CI, 1.56–12.32) were significantly associated with higher ADL dependence. Chronic obstructive pulmonary disease (COPD) was significantly associated with lower ADL dependence (OR = 0.31; CI, 0.01–0.84). The model explained 32% of the variance. The results suggest that when choosing interventions aimed at improving ADL functioning, special attention should be paid to residents living more than five years in the nursing home, with a female gender, with more severe cognitive impairments, and/or with COPD.

    Caregivers' perspectives on good care for nursing home residents with Korsakoff syndrome

    by Ineke J Gerridzen, Cees Mpm Hertogh, Karlijn J Joling, Ruth B Veenhuizen, Els Ml Verschuur, Tjeu Janssen, Marja F Depla

    Background: In the Netherlands, people with severe cognitive deficits due to Korsakoff syndrome are generally admitted to a specialized nursing home. Professional caregivers experience that these residents are often not aware of their deficits, and consequently, their willingness to accept care is relatively low. However, these residents need permanent support when performing daily tasks due to severe cognitive deficits. The combination of objective care needs and low subjective responsiveness makes caring for people with Korsakoff syndrome a complex undertaking. It is unknown how professional caregivers deal with this complex task and how they manage the associated ethical challenges. Objectives: The aim of this study was to explore the professional caregivers’ perspectives on good care for residents with Korsakoff syndrome. Methods: A qualitative study design was used. Data were collected via semi-structured interviews. The Framework Method was used for the thematic analyses of the interview data. Participants and research context: Five specialized nursing homes participated in this study. Twelve professional caregivers, including nurses, nursing assistants, and support workers, were selected based on the ability to provide rich information on the study topics and to capture a variety of demographic and professional characteristics. Ethical considerations: The institutional review board of the VU University Medical Center Amsterdam approved the research protocol. The study was conducted in accordance with the ethical principles for medical research involving human subjects. Findings: Three perspectives on good care emerged: (1) making daily life a joint effort, (2) being steadfast, and (3) treating with respect. Discussion and conclusion: Professional caregivers try to achieve responsiveness in people with Korsakoff syndrome in three different ways. These perspectives reflect fundamentally different views on the care relationship and the autonomy of the resident. By elucidating the three perspectives, we hope to promote the practitioners’ reflection on their own ideas about good care for people with Korsakoff syndrome.

    Awareness and its relationships with neuropsychiatric symptoms in people with Korsakoff syndrome or other alcohol‐related cognitive disorders living in specialized nursing homes

    by Ineke J. Gerridzen, Karlijn J. Joling, Marja F. Depla, Ruth B. Veenhuizen, Els M.L. Verschuur, Jos W.R. Twisk, Cees M.P.M. Hertogh

    Objectives: Impaired awareness of functional deficits is often observed in people with Korsakoff syndrome (KS) and may result in refusal of care, although this area has been understudied. This study aimed to investigate levels of impaired awareness and their relationships with neuropsychiatric symptoms (NPS) in people with KS residing in specialized nursing homes.Methods: A cross‐sectional, observational study was conducted among 215 residents with KS or other alcohol‐related cognitive disorders. Awareness was measured with the Patient Competency Rating Scale (PCRS). NPS and subsyndromes were measured with the Neuropsychiatric Inventory–Questionnaire (NPI‐Q). Adjusted multilevel regression analyses were performed to examine the relationships between the level of awareness and NPS.Results: The mean level of impaired awareness was 39.3 (SD = 19.9) indicating moderate impairment. Twenty‐nine percent of the residents had no or mildly impaired awareness; 37% were moderately impaired, and 34% were severely impaired. Residents with moderately impaired awareness showed more severe apathy than residents with no or mildly impaired awareness (difference 1.23; 95% CI 1.02‐1.48; p = 0.03). No associations were found between the level of awareness and other NPI outcomes. Cognitive functioning seems to have the strongest impact on the association between level of awareness and NPS in KS residents.Conclusions: Impaired awareness of functional deficits is highly common in KS residents; however, apart from apathy, is not significantly related with NPS. Additional research should further examine, which interventions are effective in dealing with impaired awareness in these people, particularly when apathy is present.

    Prevalence and severity of behavioural symptoms in patients with Korsakoff syndrome and other alcohol‐related cognitive disorders: a systematic review

    by Ineke J. Gerridzen, Wiltine G. Moerman‐Van Den Brink, Marja F. Depla, Els M. L. Verschuur, Ruth B. Veenhuizen, Johannes C. van der Wouden, Cees M. P. M. Hertogh, Karlijn J. Joling

    Objective: Experiences from clinical practice suggest that behavioural symptoms in patients with Korsakoff syndrome (KS) are a frequent problem. Knowledge about behavioural symptoms is important in understanding and managing these symptoms. The aim of this study is to review the prevalence and severity of behavioural symptoms in KS.Methods: Relevant articles were identified by searching Medline (PubMed), PsycINFO, Embase and CINAHL up to 4 June 2014. Two reviewers independently selected the studies, extracted their baseline data and assessed methodological quality using a standardized checklist.Results: Fifteen studies fulfilled the inclusion criteria. A diversity of diagnoses was used indicating that KS and other alcohol‐related cognitive disorders and terms were used interchangeably. None of the studies were primarily designed to estimate the prevalence or severity of behavioural symptoms in patients with KS. Most studies had serious methodological limitations. The reported prevalence estimates of behavioural symptoms in the included studies varied strongly. Most prevalent were depressive symptoms and disorders (2–50%, median 27%) and agitation and aggression (10–54%, median 27%). None of the reported, mean severity estimates met pathological thresholds. The highest severity estimates were found for apathy.Conclusions: Good quality studies on behavioural symptoms in patients with KS are lacking. Observational research designed to provide reliable estimates of the prevalence and severity of behavioural symptoms in patients with KS is needed. This could improve understanding and managing these symptoms and help care staff to better support the needs of this specific patient group. © 2016 The Authors.
