Elderspeak in Acute Hospitals? The Role of Context, Cognitive and Functional Impairment.

Older adults are often exposed to elderspeak, a specialized speech register linked with negative outcomes. However, previous research has mainly been conducted in nursing homes without considering multiple contextual conditions. Based on a novel contextually-driven framework, we examined elderspeak in an acute general versus geriatric German hospital setting. Individual-level information such as cognitive impairment (CI) and audio-recorded data from care interactions between 105 older patients (M = 83.2 years; 49% with severe CI) and 34 registered nurses (M = 38.9 years) were assessed. Psycholinguistic analyses were based on manual coding (κ = .85 to κ = .97) and computer-assisted procedures. First, diminutives (61%), collective pronouns (70%), and tag questions (97%) were detected. Second, patients' functional impairment emerged as an important factor for elderspeak. Our study suggests that functional impairment may be a more salient trigger of stereotype activation than CI and that elderspeak deserves more attention in acute hospital settings.

Nurses' emotional tone toward older inpatients: Do cognitive impairment and acute hospital setting matter?

The emotional tone of nurses' voice toward residents has been characterized as overly controlling and less person-centered. However, it is unclear whether this critical imbalance also applies to acutely ill older patients, who represent a major subgroup in acute hospitals. We therefore examined nurses' emotional tone in this setting, contrasting care interactions with severely cognitively impaired (CI) versus cognitively unimpaired older patients. Furthermore, we included a general versus a geriatric acute hospital to examine the role of different hospital environments. A mixed-methods design combining audio-recordings with standardized interviews was used. Audio-recorded clips of care interactions between 34 registered nurses (M age = 38.9 years, SD = 12.3 years) and 92 patients (M age = 83.4 years, SD = 6.1 years; 50% with CI) were evaluated by 12 naïve raters (M age = 32.8 years, SD = 9.3 years). Based on their impressions of the vocal qualities, raters judged nurses' emotional tone by an established procedure which allows to differentiate between a person-centered and a controlling tone (Cronbach's α = .98 for both subscales). Overall, findings revealed that nurses used rather person-centered tones. However, nurses' tone was rated as more controlling for CI patients and in the geriatric hospital. When controlling for patients' functional status, both effects lost significance. To our knowledge, this is the first study that examined nurses' emotional tone in the acute hospital setting. Findings suggest that overall functional status of older patients may play a more important role for emotional tone in care interactions than CI and setting differences.

Communication behavior of cognitively impaired older inpatients : A new setting for validating the CODEM instrument.

BACKGROUND AND OBJECTIVE: Acutely ill older patients with cognitive impairment represent a major subgroup in acute care hospitals. In this context, communication plays a crucial role for patients' well-being, healthcare decisions, and medical outcomes. As validated measures are lacking, we tested the psychometric properties of an observational instrument to assess Communication Behavior in Dementia (CODEM) in the acute care hospital setting. As a novel feature, we were also able to incorporate linguistic and social-contextual measures. MATERIAL AND METHODS: Data were drawn from a cross-sectional mixed methods study that focused on the occurrence of elderspeak during care interactions in two German acute care hospitals. A total of 43 acutely ill older patients with severe cognitive impairment (CI group, Mage ± SD = 83.6 ± 5.7 years) and 50 without cognitive impairment (CU group, Mage ± SD = 82.1 ± 6.3 years) were observed by trained research assistants during a standardized interview situation and rated afterwards by use of CODEM. RESULTS: Factor analysis supported the expected two-factor solution for the CI group, i.e., a verbal content and a nonverbal relationship aspect. Findings of the current study indicated sound psychometric properties of the CODEM instrument including internal consistency, convergent, divergent, and criterion validity. CONCLUSION: CODEM represents a reliable and valid tool to examine the communication behavior of older patients with CI in the acute care hospital setting. Thus, CODEM might serve as an important instrument for researcher and healthcare professionals to describe and improve communication patterns in this environment.

Understanding depressive symptoms in nursing home residents: the role of frequency and enjoyability of different expanded everyday activities relevant to the nursing home setting.

Depressive symptoms are highly prevalent in nursing home (NH) residents. We assume that enjoyability, besides frequency of activities, is an important facet of expanded everyday activities (EEAs; Baltes et al., in: Baltes and Mayer (eds) The Berlin aging study, University of California Press, Berkeley, 2001) and affects residents' depressive symptoms. Furthermore, we assume that associations with depressive symptoms vary for different EEAs, namely contact with co-residents and staff and participation in organized in-home activities. To investigate these associations, longitudinal data from 160 residents (M age = 83.1 years, SD = 9.8 years, 73% female) of two German NHs, assessed across four measurement occasions each 3 months apart, were analyzed. Depressive symptoms were assessed by the Geriatric Depression Scale-Residential (GDS-12R); the frequency of EEAs and their enjoyabilities were assessed via proxy ratings and interviews, respectively. As data from the completed Long-Term Care in Motion intervention study were used, 49% of the sample also received a physical activity intervention. Generalized linear mixed models were run to test the hypothesized effects as flexibly as possible, accounting for non-normality of the GDS-12R and controlling for residents' intervention status. The results showed that the interaction effect of the enjoyability of contact with co-residents and contact frequency was relevant for residents' depressive symptoms rather than the effect of contact frequency alone. The frequency of staff contact was only marginally associated with fewer depressive symptoms. Further, enjoying participating in organized in-home activities was associated with fewer depressive symptoms. In conclusion, findings support our conceptually driven expectation of differential effects in terms of different EEAs on depressive symptoms.

Interactive effects of conditioned pain modulation and temporal summation of pain-the role of stimulus modality.

Conditioned pain modulation (CPM) and temporal summation of pain (TSP) are 2 experimental paradigms capturing endogenous pain modulation, which have repeatedly demonstrated clinical relevance. Conditioned pain modulation describes the inhibition of the pain response to a test stimulus (Ts) when a second noxious stimulus, the conditioning stimulus (CS), is concurrently applied. Temporal summation of pain describes the enhanced pain response to a series of stimuli compared with single stimuli. Temporal summation of pain-limiting effects of CPM are likely but may depend on the stimulus modality of the Ts. This study aimed at investigating these differential effects of stimulus modality. Thirty-five healthy volunteers completed 2 experimental blocks (Ts modality: pressure vs heat) in balanced order. Both blocks consisted of 3 conditions: baseline (no CS), CPM1 (nonpainful CS: 42°C water bath), and CPM2 (painful CS: 46°C water bath). Single stimuli and series of stimuli were alternatingly applied to assess TSP by means of a Numerical Rating Scale. Both TSP and CPM were successfully induced with no difference between the 2 Ts modalities. We also detected a significant interaction between TSP and CPM, with higher pain reduction for a series of Ts compared with single Ts during the painful CS. Interestingly, this interaction was modality-dependent: TSP for heat Ts was completely abolished by CPM, whereas this was not the case for pressure Ts. Our findings suggest different forms of central sensitization induced by TSP using either heat or pressure stimuli, which differ in their susceptibility to CPM. Clinical implications and directions for future research are discussed.

Does a physical activity program in the nursing home impact on depressive symptoms? A generalized linear mixed-model approach.

OBJECTIVES: Physical activity (PA) may counteract depressive symptoms in nursing home (NH) residents considering biological, psychological, and person-environment transactional pathways. Empirical results, however, have remained inconsistent. Addressing potential shortcomings of previous research, we examined the effect of a whole-ecology PA intervention program on NH residents' depressive symptoms using generalized linear mixed-models (GLMMs). METHOD: We used longitudinal data from residents of two German NHs who were included without any pre-selection regarding physical and mental functioning (n = 163, Mage = 83.1, 53-100 years; 72% female) and assessed on four occasions each three months apart. Residents willing to participate received a 12-week PA training program. Afterwards, the training was implemented in weekly activity schedules by NH staff. We ran GLMMs to account for the highly skewed depressive symptoms outcome measure (12-item Geriatric Depression Scale-Residential) by using gamma distribution. RESULTS: Exercising (n = 78) and non-exercising residents (n = 85) showed a comparable level of depressive symptoms at pretest. For exercising residents, depressive symptoms stabilized between pre-, posttest, and at follow-up, whereas an increase was observed for non-exercising residents. The intervention group's stabilization in depressive symptoms was maintained at follow-up, but increased further for non-exercising residents. CONCLUSION: Implementing an innovative PA intervention appears to be a promising approach to prevent the increase of NH residents' depressive symptoms. At the data-analytical level, GLMMs seem to be a promising tool for intervention research at large, because all longitudinally available data points and non-normality of outcome data can be considered.

Pushing the Boundaries: A Physical Activity Intervention Extends Sensor-Assessed Life-Space in Nursing Home Residents.

Background and Objectives: To determine whether a multicomponent, individually tailored intervention to promote physical activity (PA) enhances life-space (LS) utilization in nursing home (NH) residents and whether intervention effects can be sustained at follow-up after continuation of the program as part of institutional daily routines. Research Design and Methods: Pre-post-assessed controlled trial in two highly similar NHs with a 3month follow-up in 143 NH residents (intervention group: n = 78; control group: n = 65) and LS as primary outcome. The PA promoting intervention consisted of several components (group sessions; individual exercise; serious games training; competence training for staff) tailored to residents' individual functional capacity. LS was innovatively assessed via an indoor wireless sensor network including three assessment-specific LS parameters: overall LS score (LSSc), time spent away from the private room (TAFR), and the maximally distal zone from private room visited (MaxZ). To exploit the available intervention-control comparative data in the best way possible, a generalized linear mixed model approach was applied. Results: At post-test, intervention participants had a significantly higher overall LSSc, spent more TAFR, and had extended their MaxZ as compared to controls. At follow-up, a significant group difference remained for MaxZ. Discussion and Implications: A PA intervention in the NH setting impacts on LS utilization as measured using sensor-based assessment. The program has proven its practical sustainability when being handed over to NH personnel for continuation in daily practice. Further research is needed to determine whether an increase in LS utilization also impacts on social participation and quality of life.

Life-space and movement behavior in nursing home residents: results of a new sensor-based assessment and associated factors.

BACKGROUND: Studies on life-space (LS) and its determinants have previously been limited to community-dwelling subjects but are lacking in institutionalized older persons. The purpose of this study was to provide an advanced descriptive analysis of LS in nursing home residents and to identify associated factors based on an established theoretical framework, using an objective, sensor-based assessment with a high spatiotemporal resolution. METHODS: Cross-sectional study in two nursing homes in Heidelberg, Germany (n = 65; mean age: 82.9 years; 2/3 female). Changes of location in the nursing home (Transits) as well as time spent away from the private room (TAFR) were assessed using a wireless sensor network. Measures of physical, psychosocial, cognitive, socio-demographic, and environmental factors were assessed via established motor performance tests, interviews, and proxy-reports. RESULTS: LS of residents was largely restricted to the private room and the surrounding living unit (90%); 10% of daytime was spent outside the living unit and/or the facility. On average, TAFR was 5.1 h per day (±2.3; Range: 0-8); seven Transits (6.9 ± 3.2; Range: 0-18) were performed per day. Linear regression analyses revealed being male, lower gait speed, higher cognitive status, and lower apathy to be associated with more Transits; higher gait speed, lower cognitive status, and less depressive symptoms were associated with more TAFR. LS was significantly increased during institutional routines (mealtimes) as compared to the rest of the day. CONCLUSIONS: The sensor-based LS assessment provided new, objective insights into LS of institutionalized persons living in nursing homes. It revealed that residents' LS was severely limited to private rooms and adjacent living units, and that in institutional settings, daily routines such as meal times seem to be the major determinant of LS utilization. Gait speed, apathy, and depressive symptoms as well as institutional meal routines were the only modifiable predictors of Transits and/or TAFR, and thus have greatest potential to lead to an enhancement of LS when targeted with interventions.
