Self-management processes, sedentary behavior, physical activity and dietary self-management behaviors: impact on muscle outcomes in continuing care retirement community residents.

BACKGROUND: Despite the known benefits of non-sedentary behavior, physical activity, and protein and caloric intake to health and muscle mass, strength, and function, many older adults do not meet physical activity and dietary recommendations. A better understanding of the factors associated with sedentary behavior, physical activity and dietary self-management behaviors, and muscle outcomes (muscle mass, strength, and function) is needed, particularly among continuing care retirement community residents. The objective of this study was to examine the factors associated with sedentary behavior, physical activity and dietary self-management behaviors, and muscle outcomes among continuing care retirement community residents. It also aimed to determine whether sedentary behavior and physical activity and dietary self-management behaviors mediate the relationships between self-efficacy, goal congruence, aging expectations, social support, and muscle outcomes. METHODS: A sample of 105 continuing care retirement community residents (age > 70 years) participated in this correlational, cross-sectional study. Questionnaires on pain, self-efficacy, goal congruence, aging expectation, social support, and daily protein and caloric intake were administered. Physical activity and sedentary behavior (ActiGraph wGT3X-BT), muscle mass (ImpediMed SFB7), muscle strength (Jamar Smart Digital Hand Dynamometer), and muscle function (Short Physical Performance Battery) were measured. Multiple regression, logistic regression, and mediation analyses were performed. RESULTS: Low goal congruence predicted engagement in sedentary behavior and light physical activity. Higher levels of self-efficacy and social support were associated with increased likelihoods of achieving greater moderate physical activity and meeting daily recommendations for caloric intake, respectively. Self-efficacy and goal congruence predicted muscle function and strength. Moreover, sedentary behavior and achieving greater moderate physical activity were found to partially but significantly mediate the relationship between self-efficacy and muscle function. CONCLUSION: Future research should evaluate whether attempts to reduce sedentary behavior and promote physical activity and dietary self-management behaviors and muscle outcomes are more successful when modifications to the self-management process factors are also targeted.

Do Warmed Blankets Change Pain, Agitation, Mood or Analgesic Use Among Nursing Home Residents?

BACKGROUND: Pain, agitation, and thermal discomfort are common symptoms of older adults residing in nursing homes. Nonpharmacologic interventions are recognized as a best practice strategy for people living in nursing homes because of their low adverse effect profile and increased evidence of effectiveness. Warmed blankets have not been empirically tested for use in long-term care. AIMS: The purpose of this quality improvement project was to describe the use of warmed blankets in a nursing home setting and determine if use was associated with changes in pain, agitation, mood, or analgesic use. DESIGN: A pretest posttest design was used along with a comparison of intact groups. SETTINGS: The setting was one 160-bed skilled long-term care facility. PARTICIPANTS/SUBJECTS: There were 141 residents eligible since they did not have a condition that could be worsened by superficial heat. METHODS: Warmed blankets were unfolded and placed over residents with pain, agitation, or thermal discomfort. Short-term pain measures included use of the Revised FACES Pain Scale, the PAINAD (Pain Assessment in Advanced Dementia) scale, and the Brief Agitation Rating Scale. Long-term measures were taken from the electronic medical record. RESULTS: Of the 141 eligible residents, 24.1% (n = 34) received a warmed blanket over the 1- month study period. There were statistically significant decreases in both pain level and agitation among baseline, 20 minutes after application, and the subsequent shift assessments (p < .001). There were also long-term changes in the number of pain complaints (p = .040), severity of pain complaints (p = .009), and as-needed analgesic use (p = .011). There were no statistically significant differences between the treated group and comparison group on any long-term measures. CONCLUSIONS: Warmed blankets are a low-cost intervention with a high potential for bringing comfort to nursing home residents.

Evaluation of an ultraviolet room disinfection protocol to decrease nursing home microbial burden, infection and hospitalization rates.

BACKGROUND: The focus of nursing home infection control procedures has been on decreasing transmission between healthcare workers and residents. Less evidence is available regarding whether decontamination of high-touch environmental surfaces impacts infection rates or resident outcomes. The purpose of this study was to examine if ultraviolet disinfection is associated with changes in: 1) microbial counts and adenosine triphosphate counts on high-touch surfaces; and 2) facility wide nursing home acquired infection rates, and infection-related hospitalization. METHODS: The study was conducted in one 160-bed long-term care facility. Following discharge of each resident, their room was cleaned and then disinfected using a newly acquired ultraviolet light disinfection device. Shared living spaces received weekly ultraviolet light disinfection. Thirty-six months of pretest infection and hospitalization data were compared with 12 months of posttest data. Pre and posttest cultures were taken from high-touch surfaces, and luminometer readings of adenosine triphosphate were done. Nursing home acquired infection rates were analyzed relative to hospital acquired infection rates using analysis of variance procedures. Wilcoxon signed rank tests, The Cochran's Q, and Chi Square were also used. RESULTS: There were statistically significant decreases in adenosine triphosphate readings on all high-touch surfaces after cleaning and disinfection. Culture results were positive for gram-positive cocci or rods on 33% (n = 30) of the 90 surfaces swabbed at baseline. After disinfectant cleaning, 6 of 90 samples (7.1%) tested positive for a gram-positive bacilli, and after ultraviolet disinfection 4 of the 90 samples (4.4%) were positive. There were significant decreases in nursing home acquired relative to hospital-acquired infection rates for the total infections (p = .004), urinary tract infection rates (p = .014), respiratory system infection rates (p = .017) and for rates of infection of the skin and soft tissues (p = .014). Hospitalizations for infection decreased significantly, with a notable decrease in hospitalization for pneumonia (p = .006). CONCLUSIONS: This study provides evidence that the pulsed-xenon ultraviolet disinfection device is superior to manual cleaning alone for decreasing microbes on environmental surfaces, as well as decreasing infection rates, and the rates of hospitalization for infection. Results suggest that placing a stronger emphasis on environmental surface disinfection in long-term care facilities may decrease nursing home acquired infections.

Nurses' Experience With and Perception of Barriers to Promoting Mobility in Hospitalized Older Adults: A Descriptive Study.

The purpose of the current study was to examine nurses' barriers, including knowledge, attitude, and external barriers, to promoting physical activity in hospitalized older adults. Differences between the perceptions of barriers based on nurses' experience were also examined. A behavioral framework classifying nurse knowledge, nurse attitude, and external barriers was used for the study. Eighty-five nurses were recruited from two community-based hospitals in the Pacific Northwest. The findings suggest that nurses with varying levels of experience perceive a variety of barriers to promoting mobility in hospitalized older adults. Nurses with ≤5 years of experience perceived that they may lack knowledge and training to safely mobilize hospitalized patients and make appropriate referrals to therapists. Nurses' attitudes revealed that they collectively viewed the promotion of mobility as a priority, but novice nurses did not. Further, some nurses deferred the responsibility to promote mobility to other disciplines. [Journal of Gerontological Nursing, 43(11), 22-29.].

Patterns of New Physical Problems Emerging in Long-Term Care Residents With Dementia.

Individuals receiving skilled nursing care have multiple comorbid conditions that impact comfort and resource use. The current study describes variations in the trajectories of new physical problems emerging over 8 weeks and the predictive value for future health and behavior in a sample of 72 residents with dementia. Residents had two to 37 new physical problems occurring over 8 weeks. Sixty-five percent of the sample had five or more new problems and were identified by three unstable trajectories. Common problems, illnesses, and symptoms accounted for 28.2% of the variance in subsequent new physical problems (p < 0.001) and 25.7% of the variance in subsequent agitation (p < 0.001). This study found more new problems than earlier studies that only examined new acute illness. Findings suggest a higher intensity of need for skilled assessment and treatment than may be available in many long-term care organizations. [Journal of Gerontological Nursing, xx(x), xx-xx.].

Proton Pump Inhibitors and the Prescribing Cascade.

ACTIVITY OBJECTIVES: 1. Describe the prescribing cascade of proton pump inhibitors (PPI) in nursing home residents. 2. Identify the statistically significant factors related to the use of PPI and H2 receptor blockers. DISCLOSURE STATEMENT Neither the planners nor the authors have any conflicts of interest to disclose. The current study examined the use of proton pump inhibitor (PPI) drugs in 248 nursing home residents and factors associated with being prescribed a PPI. Ninety-three percent of residents taking a PPI had done so for longer than recommended durations. As anticholinergic burden, vitamin/supplement use, and number of oral products taken daily increased, residents were more likely to be taking a PPI. Higher anticholinergic burden (p = 0.031) and number of oral products taken daily (p = 0.04) were two statistically significant predictors in the final logistic regression model. Significant predictors of PPI use in the current study may be explained by the association between polypharmacy and dyspepsia and the lowering of esophageal sphincter pressure by anticholinergic drugs. High use of PPIs in nursing home residents may represent a prescribing cascade.

The implementation of the serial trial intervention for pain and challenging behaviour in advanced dementia patients (STA OP!): a clustered randomized controlled trial.

BACKGROUND: Pain (physical discomfort) and challenging behaviour are highly prevalent in nursing home residents with dementia: at any given time 45-80% of nursing home residents are in pain and up to 80% have challenging behaviour. In the USA Christine Kovach developed the serial trial intervention (STI) and established that this protocol leads to less discomfort and fewer behavioural symptoms in moderate to severe dementia patients. The present study will provide insight into the effects of implementation of the Dutch version of the STI-protocol (STA OP!) in comparison with a control intervention, not only on behavioural symptoms, but also on pain, depression, and quality of life. This article outlines the study protocol. METHODS/DESIGN: The study is a cluster randomized controlled trial in 168 older people (aged >65 years) with mild or moderate dementia living in nursing homes. The clusters, Dutch nursing homes, are randomly assigned to either the intervention condition (training and implementation of the STA OP!-protocol) or the control condition (general training focusing on challenging behaviour and pain, but without the step-wise approach). Measurements take place at baseline, after 3 months (end of the STA OP! training period) and after 6 months.Primary outcome measures are symptoms of challenging behaviour (measured with the Cohen-Mansfield Agitation Inventory (CMAI) and the Neuropsychiatric Inventory-Nursing Home version (NPI-NH)), and pain (measure with the Dutch version of the Pain Assessment Checklist for Seniors (PACSLAC-D) and the Minimum Data Set of the Resident Assessment Instrument (MDS-RAI) pain scale). Secondary outcome measures include symptoms of depression (Cornell and MDS-RAI depression scale), Quality of Live (Qualidem), changes in prescriptions of analgesics and psychotropic drugs, and the use of non-pharmacological comfort interventions (e.g. snoezelen, reminiscence therapy). DISCUSSION: The transfer from the American design to the Dutch design involved several changes due to the different organisation of healthcare systems. Specific strengths and limitations of the study are discussed. TRIAL REGISTRATION: Netherlands Trial Register (NTR): NTR1967.

New Problems and Iatrogenic Events Among Older Adults in the First 30 Days of Post-Acute Rehabilitation.

The current prospective study of 126 older adults examined the new problems and iatrogenic events developing in post-acute rehabilitation. Data were extracted from the electronic health record and a consensual agreement process was used for coding. Of the 578 new problems, 66% (n = 381) were not related to the primary problem treated at the hospital; 41.7% (n = 241) were iatrogenic adverse events. The median problem-free duration was 3 days and median duration to a moderate to severe problem was 8 days. Medication-related adverse events were common. This study did not show that comorbidity or functional level should be used in determining the likelihood of older adults developing new problems or iatrogenic events during post-acute rehabilitation. Inferential findings suggest older adults with a psychiatric diagnosis, cognitive impairment, or failure to thrive may require extra measures, such as comprehensive assessment and early intervention, to prevent new problems and iatrogenic events.

Do Daytime Activity, Mood and Unit Tumult Predict Nighttime Sleep Quality of Long-Term Care Residents?

Based on the premise that stressors can have a cumulative effect on people with dementia throughout the day that contributes to negative consequences later in the day, we examined if daytime activity, unit tumult, and mood were associated with sleep quality. A convenience sample of 53 long-term care (LTC) residents participated in this correlational study. Objective sleep quality was measured using actigraphy, and comorbid illness and level of dementia were control variables. Half of the sample had a sleep efficiency that was less than 80% and was awake for more than 90 min at night. Comorbid illness, negative mood at bedtime, and daytime activity level accounted for 26.1% of the variance in total sleep minutes. Census changes and the use of temporary agency staff were associated with poor sleep. Findings suggest daytime activity, mood at bedtime, and unit tumult should be considered when designing and testing interventions to improve sleep quality.

Nighttime Agitation in Persons with Dementia as a Manifestation of Restless Legs Syndrome.

OBJECTIVES: Nighttime agitation or "sundowning" is challenging for clinicians and caregivers to manage in older adults in the dementia stage of Alzheimer's disease (AD-D). Our research previously revealed that nighttime agitation might be a manifestation of restless legs syndrome (RLS). The current study aims to describe the characteristics of older adults with AD-D, nighttime agitation, and RLS, and to evaluate sleep disturbance and iron status in relation to nighttime agitation severity. DESIGN: An observational study with baseline descriptive and correlational data from a clinical trial. SETTING AND PARTICIPANTS: Long-term care (n = 69) and independent living (n = 7); age 82.91 ± 9.46 years, with AD-D, nighttime agitation, and RLS. MEASUREMENTS: Trained observers counted nighttime agitation behaviors. Independent variables were age; cognition measured by the Mini-Mental State Examination; minutes slept from actigraphy; transferrin saturation percentage (TS%) and transferrin from fasting blood samples; and illness severity using the Cumulative Illness Rating Scale for Geriatrics. Bivariate and multivariable linear regression models were generated. RESULTS: In the multivariable model, sleep minutes (P = .002) and TS% (P = .003) were negatively associated with frequency of nighttime agitation behaviors, and they explained 20% of the variance. Seventy-nine percent received 1 or more medications that worsen RLS symptoms, such as antihistamines and serotonin reuptake inhibitors. CONCLUSIONS AND IMPLICATIONS: We encourage clinicians to consider nighttime agitation as a manifestation of RLS. Treatment of iron deficiency indicated by low TS% and deprescribing medications that exacerbate RLS may decrease nighttime agitation, improve sleep, and enhance quality of life in older adults with AD-D.

The Association Between Physiological Sources of Pain and Sleep Quality in Older Adults With and Without Dementia.

The association of musculoskeletal pain, respiratory distress, gastrointestinal discomfort, and genitourinary pain to sleep quality in 89 persons with and without dementia was examined in the current exploratory, cross-sectional, observational quantitative design. Sources of pain were recorded, with 37.1% of the sample reporting urinary retention, 30.3% reporting genitourinary discomfort, and 53.9% reporting gastrointestinal discomfort. Mild scores of musculoskeletal pain and respiratory discomfort were elicited in >75% of the sample. An actigraph was used to measure sleep variables. Findings from this research illustrated dementia, gender, pillow use, respiratory distress, and urinary retention were statistically significantly associated with nighttime sleep quality. Results suggest comprehensive assessments of pain and sleep for older adults with and without dementia are needed. Developing and testing interventions that address factors contributing to sleep quality may improve outcomes. [Research in Gerontological Nursing, 13(6), 297-308.].

Restrictive Ventilatory Patterns in Residents of Continuing Care Retirement Communities.

Restrictive ventilatory patterns (RVPs) in older adults may contribute to morbidity and decreased quality of life. The purpose of this study was to begin to understand (a) the number of older adults residing in Continuing Care Retirement Communities with RVPs, (b) factors associated with RVP, and (c) whether RVP is associated with ambulation level. This descriptive study was conducted at three sites. RVP was evident in 34 of the 65 participants (52%), and 33 (97%) of these were either moderate or severely restricted. Dementia, dyspnea, kyphosis, and lower muscle strength were significant predictors of RVP. Eighty percent of the nonambulatory participants had RVP and 38% of the ambulatory participants had RVP. Designing interventions to address modifiable factors associated with RVP may prevent respiratory infections, help people to achieve better lung health, and increase physical activity tolerance.

Factors Related to Medication Self-Management in African American Older Women.

Individuals with multiple chronic diseases are often prescribed medications for each condition and thus must manage a drug regimen. Medication self-management is challenging for most individuals with chronic diseases, but it can be especially difficult for African American older women. This study investigated how medical mistrust, caregiver role strain, and other relevant variables may be associated with medication self-management behaviors (MSMB) among African American older women, and whether goal congruence and self-efficacy mediated the relationship between the predictor variables and MSMB. A sample of 116 African American older (age >50 years) women from central Milwaukee participated in this correlational, cross-sectional study. Although goal congruence and self-efficacy were not found to act as mediators, the main finding was that goal congruence, self-efficacy, and age predicted 30% of the variance in MSMB. The results suggest that it is essential to strengthen individual self-efficacy, determine the goals that individuals have for their medication regimen, and develop support mechanisms to help patients attain these goals to better manage chronic disease.

Semi-Recumbent Vibration Exercise in Older Adults: A Pilot Study of Methodology, Feasibility, and Safety.

OBJECTIVES: Older adults with impaired physical function are at risk for further functional decline in part due to limited ability to engage in regular exercise. Effective approaches to exercise in this vulnerable population are needed to improve functional capacity and optimize independence. METHODS: Thirty-two residential care apartment complex (RCAC) residents, age ≥70, with low short physical performance battery (SPPB) scores were recruited and randomly assigned to a crossover-design study exploring feasibility and safety of semi-recumbent vibration exercise in older adults living in one RCAC. The primary outcomes were retention and adherence rates and adverse events. RESULTS: The retention rate was 78%. Adherence rate was 79.7% and 78.6% during the vibration and control training sessions, respectively. Thirty-eight adverse events (AEs) occurred. Mild muscle soreness and knee pain were the only AEs related to vibration exercise. No serious adverse events (SAEs) were study-related. Participants were able to increase training intensity and load and rated the training enjoyable. CONCLUSION: Semi-recumbent vibration exercise was feasible, well tolerated, and safe in RCAC residents with reduced physical function. Future studies need to examine the effect of this type of exercise on physical function, mobility, falls, and quality of life.

Barriers to Promoting Mobility in Hospitalized Older Adults.

Hospitalized older adults who do not receive sufficient mobility are more likely to sustain negative health outcomes, including higher rates of mortality and institutionalization. Accordingly, the purpose of the current secondary data analysis was to examine the nurse-promoted mobility of hospitalized older adults and the association between nurses' barriers and nurse-promoted mobility. In addition, the relationship among patient severity of illness, proxy levels for function, and nurse-promoted mobility was examined. The final study sample included 61 nurses working in medical units caring for a total of 77 older adults. Findings suggest nurse knowledge gaps and attitude barriers could potentially influence the type and frequency of mobility they promote in older patients. A relationship was found between older patients with impaired mobility using assistive devices for mobility at home, and those at high risk for falls and nurses promoting more sedentary activity (e.g., chair sitting, walking in the room). Interestingly, nurses promoted significantly more sedentary mobility for patients with physical therapy orders. [Res Gerontol Nurs. 2018; 11(1):17-27.].

Feasibility and Pilot Testing of a Mindfulness Intervention for Frail Older Adults and Individuals With Dementia.

Mindfulness interventions have been beneficial for healthy adults and individuals experiencing a stressful medical or mental health diagnosis. The purposes of the current study were to: (a) determine feasibility of mindfulness for older adults in long-term residential settings, and (b) examine differences in outcomes between a mindfulness and cognitive activity. The current study is the first mindfulness study to include individuals in moderate and severe stages of dementia, and included 36 individuals with a range of cognitive abilities. A crossover design was used, and the intervention was feasible for continued practice by individuals with cognitive impairment. Statistically significant short-term changes in agitation, discomfort, anger, and anxiety were found. Nighttime sleep did not improve, but participants slept less during the day. Long-term changes in outcomes were not found. Mindfulness may be useful in decreasing emotional reactivity and improving well-being of older adults in long-term care. TARGETS: Individuals with multiple chronic conditions, including cognitive impairment. INTERVENTION DESCRIPTION: The Present in the Now (PIN) intervention is a mindfulness intervention with three components: attentional skill exercises, body awareness activities, and compassion meditation. MECHANISMS OF ACTION: Mindfulness acts to decrease emotional reactivity through cognitive and affective mechanisms of action and neural activation of the cingulate cortex, amygdala, and hippocampus. OUTCOMES: Agitation, affect, stress, sleep, discomfort, and communication of need. [Res Gerontol Nurs. 2018; 11(3):137-150.].

Psychosocial Factors Associated With Reduced Muscle Mass, Strength, and Function in Residential Care Apartment Complex Residents.

Sarcopenia is a major source of disability in older adults. However, limited data are available about sarcopenia components (i.e., muscle mass, strength, and function) and their relationship to psychosocial factors among older adults living in residential care apartment complexes (RCACs). The current study examined muscle mass, strength, and function and explored their relationship to self-efficacy for exercise, depressive symptoms, and social support in 31 RCAC residents. RCAC residents had lower muscle mass, strength, and function compared to values reported in studies of community-dwelling older adults. Men had higher muscle mass and strength than women. The current findings showed a trend for individuals with high self-efficacy, without depressive symptoms, and with strong social support to present numerically greater muscle mass, strength, and function. Further studies with larger samples are needed to confirm the current study findings and inform development of interventions implemented in RCAC settings. [Res Gerontol Nurs. 2018; 11(5):238-248.].

Muscle Mechanography: A Novel Method to Measure Muscle Function in Older Adults.

Muscle function decline is a commonly observed process that occurs with aging. Low muscle function, an essential component of sarcopenia, is associated with negative outcomes, including falls, fractures, and dependency. Although many tools have been developed and are used to assess muscle function in older adults, most have important limitations. Muscle mechanography is a novel method that can quantitatively assess muscle function by performing movements such as heel raises, chair rises, or jumps on a ground reaction force plate. It can also assess balance by measuring sway of the center of pressure. Muscle mechanography promises to have advantages over currently used tools, appears to have better reproducibility, and can assess a broader range of physical function-from master athletes to frail individuals. Older adults can safely perform muscle mechanography measurements. Further research is needed to determine whether muscle mechanography can predict outcomes such as falls, fractures, and mortality. [Res Gerontol Nurs. 2017; 10(1):17-24.].

Effects of the Serial Trial Intervention on discomfort and behavior of nursing home residents with dementia.

This study tested the effectiveness of the Serial Trial Intervention (STI), an innovative clinical protocol for assessment and management of unmet needs in people with late-stage dementia. A double-blinded randomized experiment was conducted in 14 nursing homes with 114 subjects. The treatment group had significantly less discomfort than the control group at posttesting and more frequently had behavioral symptoms return to baseline. The group of nurses using the STI also showed more persistence in assessing and intervening than control group nurses did. There was a statistically significant difference between the groups in the use of pharmacological, but not nonpharmacological, comfort treatments. Results suggest that the STI is effective and that effective treatment of discomfort is possible for people with late-stage dementia.
