Association of grip strength with quality of life in the chinese oldest old

Xie, B., & Ma, C. (2021). International Journal of Environmental Research and Public Health, 18(23). 10.3390/ijerph182312394
Abstract
Abstract
Emerging studies have suggested an association between grip strength and health-related quality of life (QOL). However, evidence for which specific domains of QOL are associated with grip strength remains limited and inconsistent. Particularly, such evidence is scarce in the oldest old, who constitute one of the most vulnerable populations. This cross-sectional study aimed to examine the association between grip strength and overall QOL as well as specific domains in the oldest old. It included 400 community-dwelling older adults aged 80 years or older from Shanghai, China. QOL was assessed using the WHO Quality of Life of Older Adults instrument, and grip strength was measured using a digital spring-type dynamometer. On average, the overall QOL score was 54.68 (SD = 12.05). Estimates of risk-adjusted linear regressions indicated that higher grip strength was associated with better overall QOL (β = 4.40, p < 0.001) as well as the domains of autonomy (β = 6.74, p <0.001); fulfillment with past, present, and future activities and achievements (β = 3.52, p = 0.004); and satisfaction with social participation (β = 6.72, p < 0.001). Our findings highlight the importance of maintaining or improving grip strength in delaying or reducing the decline in QOL among the community-dwelling oldest old. Also noteworthy is that the associations between grip strength and specific domains of QOL in the oldest old vary.

Continuity of Nursing Care in Home Health: Impact on Rehospitalization among Older Adults with Dementia

Ma, C., McDonald, M. V., Feldman, P. H., Miner, S., Jones, S., & Squires, A. (2021). Medical Care, 59(10), 913-920. 10.1097/MLR.0000000000001599
Abstract
Abstract
Background: Home health care (HHC) is a leading form of home and community-based services for persons with dementia (PWD). Nurses are the primary providers of HHC; however, little is known of nursing care delivery and quality. Objective: The objective of this study was to examine the association between continuity of nursing care in HHC and rehospitalization among PWD. Research Design: This is a retrospective cohort study using multiple years (2010-2015) of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency. Subjects: This study included 23,886 PWD receiving HHC following a hospitalization. Measures: Continuity of nursing care was calculated using the Bice and Boxerman method, which considered the number of total visits, nurses, and visits from each nurse during an HHC episode. The outcome was all-cause rehospitalization during HHC. Risk-Adjusted logistic regression was used for analysis. Results: Approximately 24% of PWD were rehospitalized. The mean continuity of nursing care score was 0.56 (SD=0.33). Eight percent of PWD received each nursing visit from a different nurse (no continuity), and 26% received all visits from one nurse during an HHC episode (full continuity). Compared with those receiving high continuity of nursing care (third tertile), PWD receiving low (first tertile) or moderate (second tertile) continuity of nursing care had an adjusted odds ratio of 1.33 (95% confidence interval: 1.25-1.46) and 1.30 (95% confidence interval: 1.22-1.43), respectively, for being rehospitalized. Conclusions: Wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.

Effect of social participation on the development of physical frailty: Do type, frequency and diversity matter?

Xie, B., & Ma, C. (2021). Maturitas, 151, 48-54. 10.1016/j.maturitas.2021.06.015
Abstract
Abstract
Background: Little is known about the longitudinal association between social participation and incident frailty in community-dwelling older adults in general and particularly in China. This study examined the impact of type, frequency and diversity of social participation on incident physical frailty at two-year follow-up. Method: Longitudinal data from three waves of the China Health and Retirement Longitudinal Study were used. Older adults who were non-frail and aged 60 years or more at baseline and had information on physical frailty at follow-up were included. Frailty was measured using the modified frailty phenotype criteria. Social participation was measured as the type, frequency and diversity of engagement in social activities, including interacting with friends, playing group games, participating in sports clubs, community-related organizations, and voluntary activities. Results: A total of 6959 eligible respondents were included. Playing group games (OR=0.73, 95%CI=0.55–0.96) or participating in the activities of sports clubs (OR=0.54, 95%CI=0.34–0.85) once or more times per week led to a decreased risk of developing frailty in two years whereas participating in voluntary activities occasionally (OR=0.50, 95%CI=0.30–0.84) had a protective effect on the development of frailty. More diverse social participation was significantly associated with lower risk of incident frailty at two-year follow-up. Conclusions: The association between social participation and onset of physical frailty differed by the specific type and frequency of the activities that older adults engaged in. Promoting social participation of various types and at an appropriate frequency may be a promising way to mitigate the burden associated with physical frailty among older adults.

Tang, X., Ge, S., Ma, C., Chen, X., Pei, Y., Zhou, L., & Wu, B. (2021). Journal of Transcultural Nursing, 32(2), 173-179. 10.1177/1043659620953191
Abstract
Abstract
Introduction: This study aimed to evaluate the quality of home care in China using the Home Care Quality Assessment Tool (HCQuAT). Method: We recruited 38 home health agencies in Shanghai, China, which included 18 in urban areas, 11 in suburban areas, and nine in rural areas. Data on quality of home care from each agency were collected by trained staff using the HCQuAT. Results: On average, these home health agencies scored 74.28/100.00 (SD = 6.80) on the HCQuAT, with an excellence rate of 39.5% and a failing rate of 23.7%. The mean scores on the structure quality module, process quality module, and outcome quality module were 71.2 ± 21.8, 86.6 ± 9.2, and 44.1 ± 37.5, respectively. Significant differences existed across geographic locations (p =.018). Discussion: Significant variations were identified in the quality of home care across quality modules and geographic locations. Outcome quality and quality in rural areas were lower than those for their counterparts.

Xie, B., Ma, C., Chen, Y., & Wang, J. (2021). Health and Social Care in the Community, 29(1), 294-303. 10.1111/hsc.13092
Abstract
Abstract
This cross-sectional study aimed to determine the prevalence of the co-occurrence of physical frailty and cognitive impairment and to identify its associated demographic, psychosocial and behavioural factors. Participants were recruited from 32 neighbourhoods using multistage sampling method in Xuhui District, Shanghai, China. A total of 1585 older adults were included who lived in community, were 75 years or older and without a clinical diagnosis of dementia. Based on the presences of frailty (using the modified frailty phenotype criteria) and/or cognitive impairment (using Chinese version Mini-Mental Status Examination stratified by educational level), the participants were classified into four groups: normal, cognitive impairment alone, frailty alone and co-occurrence. Multinomial logistic regression analyses were conducted to identify the demographic, psychosocial (depression, social participation and social support) and behavioural (sedentary lifestyle and sleep problems) characteristics associated with the co-occurrence of physical frailty and cognitive impairment. The prevalence of frailty alone, cognitive impairment alone and the co-occurrence of physical frailty and cognitive impairment in the study sample were 7%, 26.94% and 7.19% respectively. The results of multinomial logistic regression show the following characteristics significantly associated with the co-occurrence of physical frailty and cognitive impairment: advanced age (81–85 years old, Odds Ratio, OR = 1.99, 95% CI = 1.10–3.59; 86 years or older, OR = 6.43, 95% CI = 3.66–11.29), number of co-morbidities (OR = 1.34, 95% CI = 1.01–1.77), depression (OR = 3.88, 95% CI = 2.39–6.29), social participation (OR = 0.61, 95% CI = 0.39–0.96), sedentary lifestyle (OR = 2.69, 95% CI = 1.66–4.34) and sleep problems (insomnia occasionally, OR = 1.84, 95% CI = 1.07–3.17; insomnia every day, OR = 2.38, 95% CI = 1.33–4.26). The co-occurrence of physical frailty and cognitive impairment is a prevalent health issue in oldest old community-dwelling older adults. Advanced age, co-morbidity, depression, sedentary lifestyle and sleep problems are risk factors for cognitive frailty while good social participation may have a protective effect on it.

Where Are We and What Shall We Do Next? A Qualitative Study of the Quality of Home Care in Shanghai, China

Tang, X., Chen, X., Wu, B., Ma, C., Ge, S., Sun, H., & Zhou, L. (2021). Journal of Transcultural Nursing, 32(3), 276-285. 10.1177/1043659620911965
Abstract
Abstract
Introduction: With the increasing need for home care in Shanghai, China, it is crucial to ensure its quality. This study aimed to explore quality-related issues of home care in Shanghai, China, and identify strategies for improvement. Method: This is a descriptive qualitative study. Semistructured interviews were conducted among 27 individuals, including home care managers (n = 8), nurses (n = 10), and patients and/or their caregivers (n = 9). Colaizzi’s seven-step analysis method was used to guide data analysis. Results: Three themes emerged regarding the quality of home care in China: unsatisfactory structure quality, unsatisfactory process quality, and imperfect outcome quality evaluation system. Recommended strategies for quality improvement included issuing standards for home care evaluation, refining structure quality and process quality, and establishing an outcome quality evaluation system. Conclusions: Concerns about the quality of home care in China were identified by providers and patients. More research especially studies quantifying the care quality and its influencing factors are needed.

Ecker, S., Pinto, S., Sterling, M., Wiggins, F., & Ma, C. (2021). Geriatric Nursing, 42(6), 1556-1561. 10.1016/j.gerinurse.2021.10.007
Abstract
Abstract
This study aimed to examine the challenges and needs of certified nursing assistants (CNAs) working in nursing homes during the COVID-19 pandemic in the greater New York City area. Between September and November of 2020, a telephone survey was administered to and completed by 208 CNAs in the study area about various aspects of their working experience during COVID-19. CNAs reported significant exposure to COVID-19 and experienced additional emotional and financial strain due to the pandemic. CNAs also expressed the influence of COVID-19 on their work schedules and intent to continue working as CNAs, and strong interest in financial support and further training. This study offers empirical insights into the experiences of CNAs working in nursing homes during the pandemic, which are of unique value to inform future efforts to support CNAs and other long-term care providers in general and during public health emergencies in New York and beyond.

Extended afternoon naps are associated with hypertension in women but not in men

Yang, Y., Liu, W., Ji, X., Ma, C., Wang, X., Li, K., & Li, J. (2020). Heart and Lung, 49(1), 2-9. 10.1016/j.hrtlng.2019.09.002
Abstract
Abstract
Background: The impact of afternoon napping duration on the risk of hypertension has not been well established, particularly with regards to sex and age differences. Objective: To examine the association between afternoon napping duration and hypertension stratified by sex and age among Chinese adults over 45 years of age. Methods: The 2011–2012 survey of the China Health and Retirement Longitudinal Study (CHARLS) was used, including 7,980 participants. We conducted logistic regression models in the overall sample, and then stratified by sex and age groups. Results: Middle-aged and older women who napped over 90 min were 39% and 54% more likely to have hypertension, respectively; however, the associations were not significant in middle-aged and older men. Conclusion: Extended afternoon napping (≥90 min) was associated with hypertension in both the middle-aged women and older women but not in men. Future studies are needed to further examine the association and possible mechanisms.

Home health care services to persons with dementia and language preference

Ma, C., Herrmann, L., Miner, S., Stimpfel, A. W., & Squires, A. (2020). Geriatric Nursing, 41(2), 165-171. 10.1016/j.gerinurse.2019.08.016
Abstract
Abstract
Despite the rapid increase in the number of persons with dementia (PWD) receiving home health care (HHC), little is known of HHC services patterns to PWD of varied backgrounds, including language preference other than English. Analyzing data of 12,043 PWD from an urban home health agency, we found on average PWD received 2.48 skilled visits or 1.88-hour skilled care and 5.81 aide visits or 24.13-hour aide care weekly. Approximately 63% of the skilled visits were from nurses. More non-English preferred PWD received aide visits, compared to English preferred PWD (44% vs. 36%). The type and intensity of HHC services were associated with language preference; when stratified by insurance, non-English preference was still significantly associated with more HHC aide care. Our study indicated that HHC services (both type and amount) varied by language preference and insurance type as an indicator of access disparities was a significant contributor to the observed differences.
