GENDER DIFFERENCES IN INTERACTIONS AND WELL-BEING AMONG HOSPITALIZED PATIENTS LIVING WITH DEMENTIA

Abstract While the incidence of dementia is generally higher in women compared to men, gender differences in interactions and well-being in dementia is still unclear. This study examined gender differences in interactions and well-being among hospitalized patients living with dementia. A total of 140 hospitalized patients (53% female and 47% male) were included in the analysis. On average, the participants were 81.43 years old (SD= 8.29), had positive interactions with staff based on higher scores on Quality of Interaction Schedule, QUIS (5.81, SD= 1.36), and fair emotional well-being based on lower scores on Cornell Scale for Depression in Dementia, CSDD (7.79, SD= 5.59). Although men seemed to have more positive interactions (male=6.07, SD=1.13; female=5.59, SD=1.51) and greater wellbeing (male=7.52, SD=4.77; female=8.03, SD=6.25) than women, there were no statistically significant gender differences observed in linear models with appropriate covariates. Future work should continue to explore gender differences in interactions and well-being.

Gender differences in interactions and depressive symptoms among hospitalized older patients living with dementia

Alzheimer’s disease or a related dementia (ADRD) disproportionately affects women with two-thirds of individuals with ADRD comprised of women. This study examined gender-related differences in the quality of staff-patient interactions and depressive symptoms among hospitalized older patients living with dementia. This secondary analysis utilized baseline data of 140 hospitalized older patients with dementia who participated in the final cohort of a randomized controlled trial (ClinicalTrials.gov identifier: NCT03046121) implementing Family centered Function-focused Care (Fam-FFC). On average, the participants (male = 46.1%, female = 52.9%) were 81.43 years old (SD = 8.29), had positive interactions with staff and lower depressive symptoms based on Quality of Interaction Schedule (QUIS) scores and Cornell Scale for Depression in Dementia (CSDD) scores, respectively. Although males had more positive interactions (male = 6.06, SD = 1.13; female = 5.59, SD = 1.51) and lesser depressive symptoms (male = 7.52, SD = 4.77; female = 8.03, SD = 6.25) than females, no statistically significant gender differences were observed in linear models with appropriate covariates or multivariant analysis of covariant (MANCOVA). However, the multigroup regression conducted to further probe marginally significant moderation effect of gender and pain on staff-patient interactions demonstrated that greater pain was significantly related to lower quality or less positive staff-patient interactions for females compared to males (χ 2 diff (1) = 4.84, p = .03). Continued evaluation of gender differences is warranted to inform care delivery and interventions to improve care for hospitalized older patients with dementia.

Use of the Quality of Interactions Schedule (QuIS) in assessing negative staff-patient interactions in acute care settings for older people: A content validation study.

The Quality of Interactions Schedule (QuIS) is an observational tool to assess the quality of staff-patient interactions in a healthcare context. QuIS is a promising measure for the evaluation of compassionate care, particularly where care is being delivered to patient populations, such as older people, who may be excluded from self-completion data collection methods. This study investigates the content validity of QuIS in identification of negative staff-patient interactions in acute care. Staff-patient interactions (n=1598) on adult inpatient units with a high proportion of older patients in two UK National Health Service hospitals were observed and rated using QuIS. When rating interactions as negative quality, observers recorded brief field notes to explain the rating. Content analysis was used to develop categories of negative interaction type. These categories were compared with the QuIS negative interaction definitions. Eighty-eight negative ratings were accompanied by a field note that could be used in the analysis. Five interaction categories were identified: Patient calls for help, call not acknowledged; Staff focused on task and appear to ignore/not hear patient; Patient-led interactions appear dismissed or ignored; Patient prevented from doing something without explanation; Staff interact with each other or talk to relatives, not including patient. There was clear association between the derived categories and QuIS guidance for negative ratings. These findings support the validity of QuIS data in relation to measurement of interaction quality in acute care settings. Extending the research to a wider range of settings would be useful.

Reliability and Validity Testing of the Quantified Quality of Interaction Schedule.

The purpose of this study was to test the reliability and validity of the Quality of Interactions Schedule (QuIS) using a quantification scoring approach. Baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) study was used. A total of 553 residents participated. There was evidence of inter-rater reliability with Kappa scores of .86 to 1.00 and internal consistency based on the Rasch analysis (item reliability of .98). There was some support for validity based on item fit and hypothesis testing as resistiveness to care was significantly associated with total QuIS scores. This study supports the use of the quantified QuIS to evaluate the quality of interactions over time and to test interventions to improve interactions.

The Influence of Race and Gender on Staff-Resident Interactions in Nursing Homes

Communication and interactions are an integral part of care in long-term care settings. Resident variables, such as race and gender, shape communication and interaction between staff and residents. The Quality of Interactions Schedule (QuIS) was developed to measure the quality of verbal and nonverbal interactions among nursing staff and older adults initially for those in acute care and later used as well in a variety of long term care settings. A quantified measurement of the quality of interactions between residents and staff was created to quantify the QuIS. The purpose of this study was to describe the gender and racial differences in scored quality of interactions. Data for the present study was based on baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) implementation study. A total of 535 residents from 55 settings were included in the analyses. An analysis of covariance was conducted to determine a difference in QuIS scores between males and females while controlling for age. The second model tested for differences in QuIS scores between blacks and whites while controlling for age and gender. There was not a statistically significant difference in QuIS scores between male and female residents. There was a significant difference in QuIS scores between those who were black versus white, such that those who were black received more positive interactions from staff than those who were white. Future work should focus on a deeper examination of resident factors and staff factors that may influence these interactions.

The Quality of Interactions Between Staff and Residents With Cognitive Impairment in Nursing Homes

Background: Positive and effective staff–resident interactions are imperative to adequately assess and meet the needs of cognitively impaired residents in nursing homes and optimize their quality of life. Purpose: The purpose of this study was to quantify, describe, and analyze the interaction between staff and cognitively impaired residents in nursing homes, using the Quality of Interaction Schedule (QuIS). Specifically, the following aims were addressed— Aim 1: To quantify and describe the quality of interactions between staff and cognitively impaired residents in nursing homes. Aim 2: To analyze whether the quality of staff–resident interactions vary by resident cognitive status (moderate vs severe) and interaction characteristics (interaction location, interaction situation, interpersonal distance, type of staff, and resident level of participation). Method: This descriptive analysis utilized baseline data from the first 2 cohorts in a randomized clinical trial including 341 residents from 35 nursing homes. Results: Five hundred fifty-six staff–resident interactions were evaluated; majority were positive (n = 466, 83.8%) and the remaining were either neutral (n = 60, 10.8%) or negative (n = 30, 5.4%). The quality of interactions varied by interaction location, interpersonal distance, and resident participation. Conclusion: This study provides some current descriptive information about the quality of staff-resident interactions in nursing homes and the interaction characteristics that might impact these interactions. Future research should focus on decreasing the negative/neutral interactions and explore staff characteristics (e.g., gender, level of experience) and facility factors (e.g., size, ownership) that might influence the quality of interactions.

Association between Quality of Interactions Schedule ratings and care experiences of people with a dementia in general hospital settings: a validation study.

Establishing methods to evaluate interactions between hospital staff and patients with a dementia is vital to inform care delivery. This study aimed to assess the validity of Quality of Interactions Schedule (QuIS) ratings in relation to the care experiences of people with a dementia in a general hospital setting. Four hundred and ninety face-to-face interactions between staff and patients with a dementia (n = 107) on six medicine for older people wards in a UK National Health Service hospital were observed and rated using QuIS and the Psychological Well-Being in Cognitively Impaired Persons (PWB-CIP) tool. We also invited patient ratings for longer interactions (n = 217). Analyses explored associations between QuIS ratings, PWB-CIP ratings and patient ratings. When QuIS was rated negative, the mean researcher-rated patient psychological well-being was lower (PWB = 7.9 out of maximum score of 10) than when QuIS was non-negative (PWB = 8.8, p = 0.036). Negative QuIS ratings were associated with negative ratings on seven out of ten individual PWB-CIP items. When QuIS was rated negative, the associated patient rating was 4% less likely to be 'happy'. The patient was also 4% more likely to rate the interaction as 'kind'. Patients struggled to participate in care ratings. Some patients found responding to researcher questions difficult or not relevant, reflecting the need for development of more suitable methods in this field. Our findings of an association between lower quality QuIS-rated interactions and lower psychological well-being lend support to the use of QuIS with patient populations that include people with a dementia.

The Quality of Interactions Schedule (QuIS) and person-centred care: Concurrent validity in acute hospital settings.

BackgroundThere is a lack of consensus on how the practices of health care workers may be assessed and measured in relation to compassion. The Quality of Interactions Schedule (QuIS) is a promising measure that uses independent observers to assess the quality of social interactions between staff and patients in a healthcare context. Further understanding of the relationship between QuIS and constructs such as person-centred care would be helpful to guide its future use in health research.ObjectiveThis study aimed to assess the validity of QuIS in relation to person-centred care measured using the CARES® Observational Tool (COT™).Methods168 nursing staff-patient care interactions on adult inpatient units in two acute care UK National Health Service hospitals were observed and rated using QuIS and COT™. Analyses explored the relationship between summary and individual item COT™ scores and the likelihood of a negative (lower quality) QuIS rating.ResultsAs the degree of person-centred care improved, QuIS negative ratings generally decreased and positive social ratings increased. QuIS-rated negative interactions were associated with an absence of some behaviours, in particular staff approaching patients from the front (relative risk (RR) 3.7), introducing themselves (RR 3.1), smiling and making eye contact (RR 3.4), and involving patients in their care (RR 3.7).ConclusionThese findings provide further information about the validity of QuIS measurements in healthcare contexts, and the extent to which it can be used to reflect the quality of relational care even for people who are unable to self-report.

104 Exploring the Utility of the VERA Framework to Improve Communication between Nursing Students and People with Dementia in Long-term Care

Abstract Background Developed by Blackhall et al. (2011), the Validation, Emotion, Reassure, Activity (VERA) communication framework seeks to provide student nurses with a guide to provide person-centred care to people living with dementia. The framework aims to enable the caregiver to communicate with the person living with dementia in a respectful manner, and accept that there is both value and meaning to the person’s speech and behaviour. This paper presents the findings from a small pilot control pre-post study which aimed to explore the impact of the VERA framework to promote person-centred communication between student nurses and older people with dementia in long term care. Methods A control group of six students, received standard communication training and ten students received additional communication training using the VERA framework. Data was collected using the non-participant observational tool Quality of Interactions Schedule (QUIS) and three self-assessment questionnaires to assess student nurses’ confidence, dementia knowledge and communication skills. Results The results of this study found that those students who received the additional VERA communication training were observed to have a significantly (Mann-Whitney U test; p = <0.05) reduced number of negative interactions with people with dementia than those students who had received standard communication training alone. In addition, student nurses trained in the VERA framework showed a significant increase (Mann-Whitney U test; p = <0.05) in their confidence to care for people with dementia than those who had received standard communication skills training. Conclusion The study finding need to be interpreted with caution given the small sample size and the pilot nature of the study. Nevertheless, these findings indicate that the VERA framework has the potential to improve (1) person-centred communication between student nurses and older people with dementia and (2) students’ confidence to care for people with dementia.

Reliability, feasibility, and validity of the quality of interactions schedule (QuIS) in acute hospital care: an observational study

BackgroundResearch into relational care in hospitals will be facilitated by a focus on staff-patient interactions. The Quality of Interactions Schedule (QuIS) uses independent observers to measure the number of staff-patient interactions within a healthcare context, and to rate these interactions as ‘positive social’; ‘positive care’; ‘neutral’; ‘negative protective’; or ‘negative restrictive’. QuIS was developed as a research instrument in long term care settings and has since been used for quality improvement in acute care. Prior to this study, its use had not been standardised, and reliability and validity in acute care had not been established.MethodsIn 2014 and 2015 a three - phase study was undertaken to develop and test protocols for the use of QuIS across three acute wards within one NHS trust in England. The phases were: (1) A pilot of 16 h observation which developed implementation strategies for QuIS in this context; (2) training two observers and undertaking 16 h of paired observation to inform the development of training protocols; (3) training four nurses and two lay volunteers according to a finalised protocol followed by 36 h of paired observations to test inter-rater agreement. Additionally, patients were asked to rate interactions and to complete a shortened version of the Patient Evaluation of Emotional Care during Hospitalisation (PEECH) questionnaire.ResultsProtocols were developed for the use of QuIS in acute care. Patients experienced an average of 6.7 interactions/patient/h (n = 447 interactions). There was close agreement between observers in relation to the number of interactions observed (Intraclass correlation coefficient (ICC) = 0.97) and moderate to substantial agreement on the quality of interactions (absolute agreement 73%, kappa 0.53 to 0.62 depending on weighting scheme). There was 79% agreement (weighted kappa 0.40: P < 0.001; indicating fair agreement) between patients and observers over whether interactions were positive, negative or neutral.ConclusionsObservers using clear QuIS protocols can achieve levels of agreement that are acceptable for the use of QuIS as a research instrument. There is fair agreement between observers and patients’ rating of interactions. Further research is needed to explore the relationship between QuIS measures and reported patient experience.

Evaluation of the 'Ladder to the Moon, Culture Change Studio Engagement Programme' staff training: Two quasi-experimental case studies.

To evaluate the impact of the CCSEP on care home staff in two care settings for older people in one nursing home and one residential home. Care homes provide personal care and accommodation for older people. The English Dementia Strategy aims to improve the quality of service provision for people with dementia. This includes specific mention of improving the quality of life in care homes and as such includes objectives related to developing the workforce knowledge and skills. The Ladder to the Moon Culture Change Studio Engagement Programme (CCSEP) is a staff training approach based on the Positive Psychology framework that uses theatre- and film-based activities. This study used a wait-list controlled design. However, the data analysis plan was amended to reflect difficulties in data collection, and a quasi-experimental case study approach was consequently utilised. Outcome measures for staff attitudes and beliefs were as follows: Sense of Competence in Dementia Care Staff; Approaches to Dementia Questionnaire; Job Satisfaction Index; Brief Learning Transfer System Inventory; and Scale of Positive and Negative Experience. The Quality of Interaction Schedule (QUIS) was used to observe changes in staff-resident interaction. Fifty staff in two care homes completed the questionnaires and forty-one undertook formal CCSEP training. In Home A (nursing home), there was no significant change in any of the measures. In Home B (residential home), the QUIS showed an increase in positive interactions post intervention; a significant increase in the Building Relationship subscale of Sense of Competence; and a significant increase in staff sense of hopefulness towards people with dementia. The Brief Learning Transfer System Inventory showed a significant decrease post-intervention. The intervention did not significantly affect the happiness or job satisfaction of care home staff. The results of this study provide tentative evidence about the efficacy of this staff training programme. Some significant improvement in staff attitudes to people with dementia, staff sense of competence and positive staff-resident interactions were found in one of two homes. It is likely that the organisational problems affecting the other care home limited the implementation and therefore efficacy of the intervention there. The results therefore suggest that when a supportive management structure is in place, CCSEP may be more effective in improving staff attitudes, sense of competence and interactions with residents.

Inter-rater reliability of the QuIS as an assessment of the quality of staff-inpatient interactions.

BackgroundRecent studies of the quality of in-hospital care have used the Quality of Interaction Schedule (QuIS) to rate interactions observed between staff and inpatients in a variety of ward conditions. The QuIS was developed and evaluated in nursing and residential care. We set out to develop methodology for summarising information from inter-rater reliability studies of the QuIS in the acute hospital setting.MethodsStaff-inpatient interactions were rated by trained staff observing care delivered during two-hour observation periods. Anticipating the possibility of the quality of care varying depending on ward conditions, we selected wards and times of day to reflect the variety of daytime care delivered to patients. We estimated inter-rater reliability using weighted kappa, κw, combined over observation periods to produce an overall, summary estimate, {widehat{upkappa}}_w . Weighting schemes putting different emphasis on the severity of misclassification between QuIS categories were compared, as were different methods of combining observation period specific estimates.ResultsEstimated {widehat{upkappa}}_w did not vary greatly depending on the weighting scheme employed, but we found simple averaging of estimates across observation periods to produce a higher value of inter-rater reliability due to over-weighting observation periods with fewest interactions.ConclusionsWe recommend that researchers evaluating the inter-rater reliability of the QuIS by observing staff-inpatient interactions during observation periods representing the variety of ward conditions in which care takes place, should summarise inter-rater reliability by κw, weighted according to our scheme A4. Observation period specific estimates should be combined into an overall, single summary statistic {widehat{upkappa}}_{w random} , using a random effects approach, with {widehat{upkappa}}_{w random} , to be interpreted as the mean of the distribution of κw across the variety of ward conditions. We draw attention to issues in the analysis and interpretation of inter-rater reliability studies incorporating distinct phases of data collection that may generalise more widely.Electronic supplementary materialThe online version of this article (doi:10.1186/s12874-016-0266-4) contains supplementary material, which is available to authorized users.

Quantity and quality of interaction between staff and older patients in UK hospital wards: A descriptive study

BackgroundThe quality of staff-patient interactions underpins the overall quality of patient experience and can affect other important outcomes. However no studies have been identified that comprehensively explore both the quality and quantity of interactions in general hospital settings. Aims & objectivesTo quantify and characterise the quality of staff-patient interactions and to identify factors associated with negative interaction ratings. SettingData were gathered at two acute English NHS hospitals between March and April 2015. Six wards for adult patients participated including medicine for older people (n=4), urology (n=1) and orthopaedics (n=1). MethodsEligible patients on participating wards were randomly selected for observation. Staff-patient interactions were observed using the Quality of Interactions Schedule. 120h of care were observed with each 2h observation session determined from a balanced random schedule (Monday-Friday, 08:00-22:00h). Multilevel logistic regression models were used to determine factors associated with negative interactions. Results1554 interactions involving 133 patients were observed. The median length of interaction was 36s with a mean of 6 interactions per patient per hour. Seventy three percent of interactions were categorized as positive, 17% neutral and 10% negative. Forty percent of patients had at least one negative interaction (95% confidence interval 32% to 49%). Interactions initiated by the patient (adjusted Odds Ratio [OR] 5.30), one way communication (adjusted OR 10.70), involving two or more staff (adjusted OR 5.86 for 2 staff, 6.46 for 3+ staff), having a higher total number of interactions (adjusted OR 1.09 per unit increase), and specific types of interaction content were associated with increased odds of negative interaction (p<0.05). In the full multivariable model there was no significant association with staff characteristics, skill mix or staffing levels. Patient agitation at the outset of interaction was associated with increased odds of negative interaction in a reduced model. There was no significant association with gender, age or cognitive impairment. There was substantially more variation at ward level (variance component 1.76) and observation session level (3.49) than at patient level (0.09). ConclusionThese findings present a unique insight into the quality and quantity of staff-patient interactions in acute care. While a high proportion of interactions were positive, findings indicate that there is scope for improvement. Future research should focus on further exploring factors associated with negative interactions, such as workload and ward culture.

Quality of Staff Service User Interaction in Two Day Centres for Adults with Learning Disabilities

This study involves quality of interaction between Day Centre staff and Service-Users with Learning Disabilities in two Day Centres (Dc1 n=50, Dc2 n=247). The Quality of Interactions Schedule (QUIS) was applied within an eight month prospective design, involving 32 visits which constructed a ‘typical day’ composed of 20-30 minute observational sessions within each Day Centre. The largest proportions of interactions were of a positive nature (87%) across both Day Centres. More positive care interactions were seen in Dc1 and significantly higher rates of positive interactions in Dc1. The greatest use of Verbal and Non-verbal interaction was observed in Dc1. Service users initiated more of the interactions in Dc2. Lengthier verbal interactions were seen in Dc1 and conversely greater amounts of short verbal interactions were seen in Dc2. Within both centres time-tables that were inspected indicated similar proportions spent in: Work, Leisure, Education, Community and Social skills sessions. In comparison to previous studies a relatively low proportion of activities were community based and social skills orientated. Results are framed within comparable observational studies in Day Centres; differences in measurement characteristics employed (Cummins, 2000, 2002) and service evaluation of quality of life in Day centres for adults with Learning Disabilities. Reliability and validity of results were also examined.

The Quality of Interactions between Staff and Psychiatric Inpatients in a Nigerian General Hospital

We examined the quality of the staff’s interactions with patients, and its relationship with ward structure, patients’ satisfaction and outcome. The Quality of Interactions Schedule was used to observe interactions with patients in two acute admission wards. In 40 h, 101 interactions were observed; 60.4% were of negative quality, 35.6% were positive and 3.9% were neutral. The majority (42.6%) were of the negative restrictive type, with the patients’ freedom being curtailed without explanation. Significantly more interactions occurred at the proximal sections of the wards, where most ward activities took place. There were no significant gender and interward differences. Interactions were not associated with clinical outcome. The patients were significantly not satisfied with the items that related to the curtailment of their freedom. They are sensitive to the quality of staff interactions while appreciating staff contribution to their care. Training programs should include staff attitudes for the improvement of the overall quality of care.

An observational study to evaluate the impact of a specialist outreach team on the quality of care in nursing and residential homes

Observations of the quality of interaction between staff and residents were made to assess the impact of training and support provided to care staff in nursing and residential homes. Assessments were made before, during and at the end of the training intervention using an adaptation of the Quality of Interactions Schedule (QUIS: Dean et al ., 1993a) modified to avoid the ceiling effect of the original version. A significant increase in the proportion of time staff spent in positive interactions with residents was observed, both in terms of direct care (plessthan 0.002) and social contact (plessthan0.05) at the end of the training schedule. Levels of resident activity were also found to increase immediately after completion of training (plessthan0.001). The results suggest that changes in the quality of interaction between staff and residents can be obtained by providing regular training and support to care workers. These findings suggest that the training schedule used in the present study may have a positive impact on the quality of care provided in nursing and residential homes for the elderly.

The relationship between staff burnout/distress and interactions with residents in two residential homes for older people.

The main hypothesis was that staff burnout/distress would be negatively associated with the quantity and quality of social interactions between staff and residents. The subsidiary hypothesis hypothesis was that 'perceived involvement in decision-making' among staff would be positively associated with the quantity and quality of staff-resident interactions. Cross-sectional and within-group. Standardized self-report questionnaires completed by staff; and non-participant, time-sampling observation and coding of staff-resident interactions. SETTING. Two independent (not-for-profit) residential care homes for older people in the UK. 18 out of 24 residential workers completed questionnaires. The 12-item General Health Questionnaire (GHQ-12); the Maslach Burnout Inventory (MBI); the Perceived Involvement Personal Questionnaire (PIPQ); and the Quality of Interactions Schedule (QUIS). Staff who reported higher levels of personal accomplishment (ie lower levels of burnout on the personal accomplishment subscale) exhibited significantly more staff-resident interactions; and staff who perceived more involvement in decisions relating to their work showed significantly fewer negative staff-resident interactions. Staff distress, emotional exhaustion and depersonalization were not found to be significantly related to the quantity or quality of staff resident interactions. The results provide some support for the hypotheses. It appears that levels of personal accomplishment and perceived involvement in decision-making among staff may significantly influence the quantity and quality of staff-resident interactions in residential settings. However, the causal relationships are uncertain, and replication of these findings is required in other contexts.
