Evolution of quality of life in patients with Korsakoff's syndrome in a long-term care facility

Development and preliminary evaluation of the QUALIKO: an observational quality of life instrument for patients with Korsakoff's syndrome

Background

To develop a Korsakoff-specific measure of quality of life (QoL), to be rated by professional caregivers, and to field-test its psychometric properties in a sample of patients with Korsakoff’s syndrome (KS) living in a specialized nursing home.

Methods

A research version of the QUALIKO was developed based on an existing instrument for dementia (the QUALIDEM), literature review and two rounds of surveys among expert professionals involved in the care for patients with KS. Next, QoL was independently rated using the preliminary QUALIKO for 77 patients with KS by two primary caregivers.

Results

The research QUALIKO consisted of 48 items describing observable behaviors across ten aspects of QoL relevant to patients with KS. Six items demonstrated poor scalability in the field test. The remaining 42 items all formed subscales with moderate to strong scalability according to Mokken scale analysis. Reliability was acceptable to good across both raters for all subscales (Mokken rho’s = 0.70–0.90), except for the two 2-item subscales of negative affect and positive self-image (Mokken rho’s = 0.47–0.71). Inter-observer agreement was excellent for five subscales (ICCs = 0.75–0.89) and fair to moderate for the other five subscales (ICCs = 0.59–0.72). The multidimensional internal structure was confirmed and all subscales were significantly correlated with primary caregivers’ global ratings of QoL except for positive self-image. Missing item values were low and floor and ceiling effects acceptable for most subscales.

Conclusions

The QUALIKO holds promise as a feasible, reliable, and valid measure of QoL in residential KS patients. Future research in larger samples is needed to confirm the psychometric dimensionality of the instrument, to gather normative data and to examine its test-retest reliability.

Quality of Life and Pain Medication Use in Persons With Advanced Dementia Living in Long-Term Care Facilities

OBJECTIVES

In residents with dementia living in a long-term care facility (LTCF), un(der)treated pain may trigger behavioral disturbances, mood syndromes, and deterioration of physical functioning and self-maintenance. Because these factors can have considerable impact on the quality of life (QoL), this study aimed to (1) compare characteristics of persons with advanced dementia living in LTCFs with and without pain medication; (2) compare QoL in these persons with and without pain, stratified by type of pain medication use; and (3) explore associations between the use of paracetamol and QoL in persons with advanced dementia living in LTCFs.

DESIGN AND SETTING

This study analyzed baseline data from the Communication, Systematic Assessment and Treatment of Pain, Medication Review, Occupational Therapy, and Safety Study; a multicenter, cluster-randomized effectiveness-implementation clinical hybrid trial in 67 Norwegian LTCF clusters.

PARTICIPANTS

In total, 407 LTCF residents (rural and urban areas) aged ≥65 years, with Functional Assessment Staging scores of 5-7 (ie, moderate to advanced dementia).

MAIN OUTCOME MEASURE

QoL as assessed by the 6 QUALIDEM (validated questionnaire to measure QoL in persons with dementia living in LTCF) domains applicable to persons with moderate to severe dementia. The association between QoL and paracetamol was estimated using linear mixed-effect models, adjusting for confounding variables.

RESULTS

62.0% used pain medication (paracetamol, opioids, or both). QoL was lower in residents using pain medication, compared with those without pain medication [mean QUALIDEM score 68.8 (standard deviation 17.4 vs) 75.5 (standard deviation 14.6), respectively, P < .001). Multilevel analysis showed that paracetamol use was not associated with QoL.

CONCLUSIONS AND IMPLICATIONS

Persons with advanced dementia living in LTCF using pain medication have a lower QoL compared with those not using pain medication. These results are of key importance for the clinician because they stress the need for regular medication review and pain management. When measured cross-sectionally, use of paracetamol is not associated with increased QoL.

The effect of errorless learning on psychotic and affective symptoms, as well as aggression and apathy in patients with Korsakoff's syndrome in long-term care facilities

ABSTRACTObjectives:Errorless learning is a promising rehabilitation principle for learning tasks in patients with amnesia, including patients with Korsakoff's syndrome. Errorless learning might possibly also contribute to decreases in behavioral and psychiatric problems, as patients in long-term care facilities become more independent after training. The aim of this study was to examine the effects of errorless learning on potential changes in psychotic and affective symptoms, aggression and apathy, in contrast with a control group who received care as usual.

METHODS

The current study is a quasi-experimental study on errorless learning and psychotic and affective symptoms, aggression, and apathy in patients with Korsakoff's syndrome, living in long-term care facilities for patients with Korsakoff's syndrome (KS) in the Netherlands. The GIP-28, HoNOS-ABI, and NVCL-20 were administered to a group of patients with KS who received errorless learning training (n = 51) and a patient control group who received care as usual (n = 31). Wilcoxon Signed-Rank Tests were performed to examine psychotic and affective symptoms, aggression, and apathy at baseline and at follow-up in the errorless learning group and the control group.

RESULTS

Errorless learning training effectively reduced psychotic symptoms (including provoked confabulations), affective symptoms, and agitation/aggression. There were no significant changes (increases nor decreases) in the control group. Levels of apathy were stable over time in both groups.

CONCLUSIONS

Results with respect to psychotic and affective symptoms, aggression, and apathy are discussed in depth. Patients with KS can become more autonomous in a cared for setting using errorless learning principles. This might also result in decreases in behavioral and psychiatric problems in patients.

The effect of errorless learning on quality of life in patients with Korsakoff's syndrome

BACKGROUND

Errorless learning (EL) is a promising rehabilitation principle for (re)learning instrumental activities in patients with amnesia, including patients with Korsakoff's syndrome (KS). Successfully (re)learning tasks might improve the sense of competence and independence, and subsequently the quality of life. Quality of life in patients with KS has received limited attention, and no studies have been conducted to experimentally examine the effect of EL on quality of life in patients in this patient group.

MATERIALS AND METHODS

The QUALIDEM, an observation scale for quality of life, was completed by professional nurses before and after EL training in a group of fifty-one patients with KS. This scale was also completed for a group of thirty-one control patients receiving care as usual but no EL training.

RESULTS

Quality of life was significantly increased on eight of the nine subscales in the Korsakoff group who participated in an EL training. There was a trend toward a significant increase in "positive affect" (ie, the ninth subscale). In contrast, no changes over time were found on any of the subscales in the control group that did not participate in any EL training.

CONCLUSION

Despite severe memory impairments, patients with KS still have the potential to (partially) (re)learn tasks using EL. This potential should be exploited, as the successes of (re)-learning might improve the quality of life of Korsakoff patients in nursing homes.
