Risk Factors for Mobility Decline in Community-Dwelling Older Adults: A Systematic Literature Review

Sleep disturbances and progression of mobility disability: Longitudinal findings from the Nurses' Health Study

Objective

To examine longitudinal associations between self-reported sleep disturbances and mobility disability progression among women, including subgroups with multiple sclerosis (MS), diabetes, and osteoarthritis (OA).

Methods

Prospective cohort study using data from Nurses' Health Study long-form questionnaires (2008, 2012, 2014, 2016). Logistic regression was used to quantify associations between sleep-related variables at baseline and subsequent increase in mobility disability.

Results

Of 70,303 women (mean age 73), 392 had MS, 7,302 had diabetes, and 24,099 had OA. Between 2008-2016, mobility disability increased by 16.9 % overall, 27.8 % in the MS subgroup, 27.0 % in the diabetes subgroup, and 23.7 % in the OA subgroup. Known/suspected obstructive sleep apnea was significantly associated with an increase in mobility disability between 2008 and 2016, overall (OR:1.4, 95 %CI:1.2,1.5), and in the diabetes (OR:1.5, 95 %CI:1.2,1.9) and OA subgroups (OR:1.2, 95 %CI:1.0,1.4), but not in the MS subgroup (OR:2.3, 95 %CI:0.6,8.9); however, across 2012-2016, this association was significant for MS (OR:4.0, 95 % CI:1.0,16.1). Suboptimal sleep duration was significantly associated with increased odds of mobility disability progression overall, but not in disease subgroups. Perception of adequate sleep was associated with lower odds of mobility disability progression overall (OR:0.82, 95 %CI:0.78,0.87) and for the OA subgroup (OR:0.83, 95 % CI:0.76,0.91). Excessive daytime sleepiness was associated with mobility disability progression overall (OR:1.2, 95 %CI:1.1,1.4) and for the OA subgroup (OR:1.2, 95 %CI:1.0,1.4).

Conclusions

Prevalent sleep disturbances could increase disability progression among women. Chronic disease populations may be uniquely vulnerable. Informed by these data, future research could offer new insight into sleep-based strategies to ameliorate mobility decline.

Virtual Assessment Protocols for Timed-Up-and-Go, 5-Repetition Chair Rise, and 1-Minute Sit-to-Stand Tests in Community-Dwelling Older Adults: Investigating Feasibility, Reliability, and Validity

OBJECTIVE

To develop and evaluate virtual assessment protocols for the Timed-Up-and-Go usual and fast pace, Chair Rise-5 repetition, and the 1-minute Sit-to-Stand tests and examine their feasibility, reliability, and validity.

DESIGN

This was a prospective cohort study, where participants engaged in up to 2 virtual assessments and data were collected prospectively for 1 year.

SETTING

Assessments took place in participants' homes in the community. Toolkits were delivered that included the required equipment and internet-enabled tablet.

PARTICIPANTS

Participants included a random sample of adults ≥65 years old who could walk 10 m without assistance from another person and communicate in English.

MAIN OUTCOME MEASURES

Falls and health care utilization data were collected for 1 year after initial assessments. Descriptive data were used to examine feasibility; intraclass correlation (ICC), and Pearson's/Spearman's correlation and areas under the curve (AUCs) were used to evaluate reliability and validity, respectively.

RESULTS

Sixty participants (mean age 76.6±5.6; 55% female) completed visit 1 and 52 completed visit 2. Technology issues were relatively common, yet no safety incidents occurred. All the virtual mobility tests demonstrated excellent test-retest (ICCs=0.86-0.95) and inter-rater (ICC=0.98-0.99) reliability. The tests had weak-to-moderate correlations with measures of physical function (r=-0.14 to -0.43) and physical activity (r=-0.19 to 0.32). Fifty-seven total falls were recorded by 28 participants (46%) over 1 year. The virtual mobility tests did not have adequate accuracy for predicting falls (AUCs=0.53-0.59), specialist (AUCs=0.48-0.60), family doctor (AUCs=0.48-0.59), or rehabilitation professional visits (AUCs=0.65-0.67), or hospitalizations (AUCs=0.56-0.63).

CONCLUSION

Results support the feasibility and reliability of virtual administration of the Timed-Up-and-Go usual and fast pace, Chair Rise-5 repitition, and 1-minute Sit-to-Stand tests. Clinicians and researchers can use the included manuals to conduct these tests virtually. Future research should examine the clinical utility of these tests for remote monitoring and mobility assessment.

The Impact of Pain on Mobility in Patients with Cancer

OBJECTIVES

Provide an overview of how pain impacts mobility in patients with cancer.

METHODS

A literature search was conducted in PubMed and on Google Scholar using search terms, cancer pain with mobility, acute and chronic pain syndromes, enhanced recovery after surgery, nursing care, and rehabilitation. Peer-reviewed research studies, review articles, and pain guidelines and position papers were reviewed to provide an overview on cancer pain, its impact on mobility, and the nurse's role in managing pain and optimizing mobility and functional outcomes.

RESULTS

Firty-two references were included in this overview. This body of literature is replete with studies on the management of pain; however, the tie between pain and mobility has not been well described aside from the breakthrough pain literature. This manuscript weaves these two important concepts together to better inform nurses and other clinicians regarding the importance of managing pain to even begin mobilizing patients, especially following surgery and for other painful conditions.

CONCLUSIONS

Oncology nurses play an integral role in assessing and managing cancer pain. It is important for nurses to recognize how their pain management interventions lead to improved mobility and functioning in patients with cancer.

IMPLICATIONS FOR NURSING PRACTICE

Nurses comprise the largest workforce around the globe and are well-equipped to assess and manage cancer pain in all cancer care settings. As leaders within the healthcare team, making recommendations to better control pain and communicating with other team members regarding the pain plan is essential in improving mobility in patients with cancer.

What mobility factors are critical to include in a comprehensive mobility discharge assessment framework for older adults transitioning from hospital-to-home in the community? An international e-Delphi study

PURPOSE

To prioritize and achieve consensus on mobility determinant factors [cognitive, financial, environmental, personal, physical, psychological, social] considered critical to include in the COmprehensive Mobility Discharge Assessment Framework (COMDAF) for older adults transitioning from hospital-to-home.

MATERIALS AND METHODS

We conducted a three-round modified e-Delphi process with 60 international experts (seven older adults, nine family caregivers, 24 clinicians, and 20 researchers) from nine countries with universal or near-universal health coverage. Expert members rated 91 factors identified from scoping reviews using a 9-point scale: not important (1-3), important (4-6), and critical (7-9).

RESULT

A total of 41 of 91 factors (45.1%) met the a-priori consensus criterion after three rounds: five cognitive, five environmental, two personal, 19 physical, six psychological, and six social factors. No financial factors reached a consensus. The older adult steering committee member recommended the addition of two environmental factors, resulting in 43 mobility factors included in the COMDAF.

CONCLUSIONS

We advanced a comprehensive mobility framework by developing, through consensus, 43 mobility factors to be assessed as part of a COMDAF. However, its use in hospital-to-home may not be feasible. Therefore, future research will determine the core mobility factors for COMDAF and which measurement instruments best measure these factors.

RELEVANCE

An interdisciplinary discharge rehabilitation team can utilize the COMDAF during hospital-to-home transition.Implications for rehabilitationMobility assessment following a hospital discharge is a complex process requiring an interdisciplinary discharge rehabilitation team.This study provided a comprehensive list of 91 factors across all seven mobility determinants (cognitive, environmental, financial, personal, physical, psychological, and social) for clinicians in other care settings to use as a starting point to determine which mobility factor should be assessed during older adults' hospital-to-home transition.This international e-Delphi study identified 43 factors within mobility determinants (cognitive, environmental, personal, physical, psychological, and social) to be included in a Comprehensive Mobility Discharge Assessment Framework to assess older adults' mobility during the hospital to home transition.Using these 43 factors, clinicians can identify which assessment tool is best suited to assess the factors while reflecting on the logistics and feasibility; this is the next phase of this project.

The Symptom Experience of Older Adults with Mobility Difficulties: Qualitative Interviews

Eighteen million older adults have mobility limitations, defined as difficulty walking a quarter of a mile or climbing stairs unassisted. Little is known about how symptom burden impacts mobility difficulty in older adults. Understanding the burden of symptoms responsible for mobility difficulties may be an area for intervention to improve mobility and to prevent adverse outcomes. We conducted 31 semi-structured qualitative interviews (one interview per participant) regarding the symptom burden experience associated with a current mobility difficulty. Thematic analysis revealed symptoms were limiting, were barriers to participation in daily activities, and produced a psychological and emotional burden that negatively impacted quality of life. Older adults employed various strategies to overcome the symptom burden. Participants also believed symptoms were a non-modifiable part of the aging process and at times felt disregarded by healthcare professionals. Future interventions should focus on reducing the symptom burden experience for older adults to improve mobility and prevent adverse outcomes.

Do the dual-task "8-foot up and go" tests provide additional predictive value for early detection of cognitive decline in community-dwelling older women?

BACKGROUND

The 8-Foot Up and Go (8UG) test is a widely used mobility assessment. Some dual-task mobility assessments have been developed to help detect cognitive decline.

AIMS

This study developed a dual-task version of 8UG test to investigate the dual-task 8UG performance and to evaluate the ability of dual-task 8UG test in detecting cognitive decline.

METHODS

A total of 101 eligible community-dwelling women aged 60-74 years were grouped into the mild cognitive impairment group (MCI, n = 49) and the non-cognitive impairment group (NCI, n = 52). The 8UG tests under single-task (ST), manual dual-task (MT), and cognitive dual-task (CT) conditions were performed respectively. The dual-task cost (DTC) and the correct response rate (CRR) were calculated to quantify the dual-task interference.

RESULTS

Participants spent more time in performing the 8UG test under dual-task conditions. No differences were observed between NCI and MCI groups for 8UG parameters under ST and MT conditions (p > 0.05). When executing CT, significant differences were found in the number of correct answers and CRR (p < 0.05). CRR showed the strongest ability to predict MCI with a cut-off point of 0.50 (71.2% sensitivity and 61.2% specificity).

DISCUSSION

Both manual and cognitive dual-task were found to interfere with the 8UG performance. CRR with cutoff point of 0.50 could be a potential predictor of MCI in community-dwelling older women.

CONCLUSIONS

The CRR of the cognitive dual-task 8UG test could be recommended as a potential predictor for the early detection of MCI in community-dwelling older women.
