Nursing Staff’s Knowledge and Attitudes towards Dementia in an Indian Nursing Home: A Qualitative Interview Study

Abstract

Background: Despite the increased prevalence of dementia in India, there is reported to be little awareness of the disease. This could lead to a late diagnosis, a reduced number of choices regarding future care, and misinterpretation of the symptoms or neglect. Taking into consideration that most nurses caring for older people in the future will work with people with dementia, there is concern that they may not be able to meet the needs of this group of patients unless they have the necessary knowledge and a positive attitude.
Aim: To explore the knowledge about and attitude towards dementia among nursing staff working in residential care facilities for older people in India.
Method: An explorative and descriptive qualitative design was used. Two semi-structured focus group interviews were conducted with nursing staff working in 6 nursing homes in India. Qualitative content analysis was used. Ethical approval was granted by the Norwegian Social Science Data Services.
Findings: The participants highlighted the following 3 dimensions in relation to their knowledge of and attitudes toward dementia in residential care facilities in India: (1) people with dementia – a walking mystery; (2) we need to go along with them, but it is challenging; and (3) if we know, we can care for them in a better way.
Conclusion: The findings revealed a wide range of differences in attitude towards and inadequate knowledge of dementia among nursing staff. However, their overall attitudes toward people with dementia was positive.

Physical performance across the cognitive spectrum and between dementia subtypes in a population-based sample of older adults: The HUNT study

Abstract

Background: Literature on physical performance in older adults across the cognitive spectrum remains inconclusive, and knowledge on differences between dementia subtypes is lacking. We aim to identify distinct physical-performance deficits across the cognitive spectrum and between dementia subtypes.
Methods: 11,466 persons were included from the 70-year-and-older cohort in the fourth wave of the Trøndelag Health Study (HUNT4 70+). Physical performance was assessed with the Short Physical Performance Battery (SPPB), 4-meter gait speed, five-times-sit-to-stand (FTSS), grip strength and one-leg-standing (OLS). Clinical experts diagnosed dementia per DSM-5 criteria. Multiple linear and logistic regression were performed to analyze differences between groups. Age, sex, education, somatic comorbidity, physical activity and smoking status were used as covariates.
Results: Gait speed declined across the cognitive spectrum, beginning in people with subjective cognitive decline (SCD). Participants with mild cognitive impairment (MCI) additionally showed reduced lower-limb muscle strength, balance and grip strength. Those with dementia scored lowest on all physical-performance measures. Participants with Alzheimer’s disease (AD) had a higher SPPB sum score and faster gait speed than participants with vascular dementia (VaD) and Lewy body dementia (LBD); participants with VaD and LBD had lower odds of being able to perform FTSS and OLS than participants with AD.
Conclusions: Physical performance declined across the spectrum from cognitively healthy to SCD to MCI and to dementia. Participants with AD performed better on all assessments except grip strength than participants with VaD and LBD. Stage of cognitive impairment and dementia subtype should guide exercise interventions to prevent mobility decline and dependency.

Skrøpelighet blant eldre pasienter med hjemmesykepleie

Abstract

Originalartikkel
Bakgrunn:
Det er et politisk ønske at eldre personer med hjelpebehov skal kunne bo hjemme så lenge som mulig og motta helsetjenester utenfor institusjon. Denne gruppens grad av skrøpelighet samt risiko for akuttinnleggelser og død, er lite studert. Hensikten med prosjektet var å studere dette gjennom to år i en middelsstor norsk kommune.
Materiale og metode
Et utvalg pasienter i Sandefjord kommune, 65 år eller eldre, med ukentlig offentlig hjemmesykepleie ble inkludert. Pasientene gjennomgikk en geriatrisk vurdering i eget hjem hvert halvår i to år. Grad av skrøpelighet ble beregnet ved hjelp av Skrøpelighetsindeks (Frailty Index). Forekomst av dødsfall og akutte sykehusinnleggelser ble registrert i to år.
Resultater:
Av 271 forespurte pasienter ble 210 inkludert. 160 pasienter (76 %) ble klassifisert som moderat eller alvorlig skrøpelige. I løpet av observasjonsperioden ble det registrert 307 akuttinnleggelser med til sammen 1 235 liggedøgn i sykehus. Sammenliknet med pasienter med alvorlig skrøpelighet var pasienter med mild skrøpelighet sjeldnere innlagt på sykehus (hasardratio (HR) 0,33; 95 % konfidensintervall (KI) 0,19–0,60). 63 (30 %) av deltakerne døde i løpet av to års observasjonstid. Dødeligheten var høyest blant pasienter med alvorlig skrøpelighet. Ved justert Cox-regresjon var økende alder assosiert med økt risiko for død, men ikke med akuttinnleggelser.
Fortolkning:
Eldre pasienter som mottar hjemmesykepleie, har høy grad av skrøpelighet, og grad av skrøpelighet er assosiert med risiko for sykehusinnleggelser og død.

Construct Validity of the Questionnaire Quality From the Patients Perspective Adapted for Surgical Prostate Cancer Patients

Abstract

Patient-reported experience measures (PREMs) are important to capture the patients’ voice. No such measure is routinely used for evaluation after robotic-assisted radical prostatectomy for prostate cancer. The aim of this study was to adapt the short version of the PREM questionnaire quality from the patients’ perspective (QPP), and assess the construct validity of this version. Quality from the patients’ perspective assesses 4 dimensions of quality of care. Involving discussion with user representatives, the QPP short version was adapted by adding 7 context-specific questions based on items from the Expanded Prostate Cancer Index Composite for Clinical Practice. This short version was answered on smartphone or tablet by 265 patients. We used exploratory factor analysis to assess dimensionality. For comparison with previous publications of the QPP, the analysis was repeated after mean imputation of missing values. The factor analysis identified 7 factors among the 30 analyzed items included in the analysis, explaining 64.9% of the variance. After imputation of missing, 2 factors explained 48.6% of the variance. None of these analysis captured the 4 dimensions of the QPP.

Staff’s perspectives on the organization of homecare services to people with dementia—A qualitative study

Abstract

Aims
The aim of the study was to explore the experiences of homecare staff about the impact of the organization of homecare services for people with dementia.

Design
This study has a qualitative, exploratory design based on a phenomenological‐hermeneutic approach, using individual in‐depth interviews with homecare staff to collect data.
Methods
A convenience sample of 14 homecare staff from five municipalities participated in the study. Main topics introduced: (a) how homecare services for people with dementia are organized and (b) challenges in respondents’ everyday practice of caring for people with dementia. Interviews were conducted from October to December 2017.
Results
Three main themes were identified from the interviews. (a) Complexity and need for individualized facilitated homecare services; homecare services were described as complex in regard to both the patient and the service. The complexity of the service made it challenging to tailor the service to the individual patient. (b) The importance of trust and relationships; establishing trust in the relationship between the patient and the staff resulted in better‐quality care. This was crucial for identifying the patient’s need for help. (c) Organizational challenges; homecare services could be vulnerable to changes in the organization. Practical tasks and following the daily scheduled task list were often prioritized at the expense of an individually tailored service.

Impact of age and CYP2D6 genotype on exposure of zuclopenthixol in patients using long-acting injectable versus oral formulation-an observational study including 2044 patients

Abstract

Abstract

Purpose: Zuclopenthixol is an antipsychotic available as oral and long-acting injectable (LAI) formulations. The aim of this study was to investigate the effect of age on zuclopenthixol exposure during oral and LAI administrations without and with adjustment for CYP2D6 genotype.

Methods: Data on serum concentrations of zuclopenthixol and CYP2D6 genotype (available for 28.2% of the population) from patients using oral or LAI zuclopenthixol were included retrospectively from a therapeutic drug monitoring service during the period 2005-2019. As a measure of exposure, dose-adjusted serum concentration (C/D ratio) was used. Based on age, patients were grouped to older (≥ 65 years) or younger (18-64 years). Linear mixed model analyses without and with adjustment for CYP2D6 genotype were used.

Results: Serum concentrations of zuclopenthixol from 1145 (14.1% older) and 899 patients (24.6% older) in the LAI and oral groups were included, respectively. Compared with younger patients, older patients had a higher C/D ratio of zuclopenthixol for LAI (+ 25-33%, p < 0.001) and oral formulation (+ 25-29%, p ≤ 0.003) without and with adjustment for CYP2D6 genotype. The doses were lower in older versus younger patients (oral: – 30%; LAI: – 20%; p < 0.001). Compared with the younger LAI users without reduced CYP2D6 function, a higher C/D ratio was observed in the older LAI users with reduced CYP2D6 function (+ 104%, p < 0.001).

Conclusion: The present study showed that zuclopenthixol exposure increases in older patients and that the older LAI users with reduced CYP2D6 function are exposed to high serum concentrations. Also, the present study showed that similar dose reductions are required for oral and LAI users.

Impact of age and gender on paliperidone exposure in patients after administration of long-acting injectable formulations-an observational study using blood samples from 1223 patients

Abstract

Purpose: Paliperidone palmitate is an antipsychotic medication available as long-acting injectable (LAI) formulations. The aim of this study was to investigate the effect of age and gender on paliperidone exposure after administration of LAI formulations.

Methods: Data on serum concentrations of paliperidone from patients using LAI during were included retrospectively from a therapeutic drug monitoring (TDM) service. Information about dose was obtained from the requisition forms. As a measure of exposure, daily dose-adjusted serum concentration (C/D ratio) was used. Based on initial analysis of C/D ratios versus age, a breaking point close to 50 years was observed, thus deciding the grouping of patients as older (≥50 years) or younger (15-49 years). Linear mixed model analyses, allowing multiple measurements per patients, were used.

Results: In total, 1223 patients were included, whereof 1158 patients used paliperidone LAI in once-monthly intervals. In these patients (27.9% older), older patients had significantly higher paliperidone C/D ratio than younger patients (+20%, p<0.001). Compared to males, females had higher C/D ratio (+14%; p<0.001). Subsequently, older female users of once-monthly LAI intervals had 41% higher paliperidone C/D ratios compared to younger males (15.0 vs. 21.2 nM/mg; p<0.001). Compared to females aged 21-30 years, females with high age (≥70 years) had at least 105% higher paliperidone C/D ratio (p<0.001).

Conclusion: The present study shows that older age and female gender are associated with higher paliperidone exposure than younger age and males, respectively. Particularly, older female patients (>50 years) are likely exposed to high concentration and cautious dosing in this subgroup is required.

Quantifying physical activity in aged residential care facilities: A structured review

Abstract

Background: Engaging aged residential care (ARC) residents with physical activity (PA) may be a useful strategy to decelerate dependence and disability. It is unclear what volume, intensity and patterns of PA ARC residents participate in. This review aims to synthesize the literature to quantify the volume, intensity and pattern of PA that ARC residents participate in across differing care levels (e.g. low, intermediate, high, mixed), and make recommendations for future research.

Methods: 30 studies of 48,760 yielded were reviewed using systematic review strategies.

Results: Questionnaires and technological tools were used to assess PA, with accelerometers employed in 70% of studies. Overall, studies reported low volumes and intensities of PA across all care levels, and suggested limited variation in patterns of PA (e.g. little day-to-day variation in total PA). There was limited inclusion of people with cognitive impairment, potentially causing representativeness bias. Findings were limited by lack of consistency in methodological approaches and PA outcomes.

Discussion: Based on findings and limitations of current research, we recommend that total volume or low-light intensity PA are more useful interventional outcomes than higher-intensity PA. Researchers also need to consider which methodology and PA outcomes are most useful to quantify PA in ARC residents.

2D Virtual Reality-Based Exercise Improves Spatial Navigation in Institutionalized Non-robust Older Persons: A Preliminary Data Report of a Single-Blind, Randomized, and Controlled Study

Abstract

Background: Spatial navigation is a prodromal dementia marker. Exercise used alongside virtual reality improves many cognitive functions, but effects on spatial navigation are still unclear.
Objective: To investigate the effect of virtual reality-based physical exercise with 2D exergames on spatial navigation in institutionalized non-robust older persons.
Method: A total of 14 older persons (aged ≧ 60) were randomly allocated to the exergame (EG) and active control (ACG) groups. EG performed exercises with 2D exergames, while the ACG used the same movements as the EG, but without the use of virtual reality. Spatial navigation was assessed through the Floor Maze Test, where the immediate maze time (IMT) and delayed maze time (DMT) were recorded.
Results: Spatial navigation was enhanced in EG participants compared to ACG individuals. A significant (p = 0.01) IMT reduction between groups was observed, while DMT time without prior planning was significantly different at the significance threshold (p = 0.07).
Conclusions: Virtual reality-based exercise improves the spatial navigation of institutionalized non-robust older persons. This study should be replicated to confirm the findings reported herein.
