Connecting the learners: improving uptake of a nursing home educational program by focusing on staff interactions

PURPOSE OF THE STUDY

The CONNECT intervention is designed to improve staff connections, communication, and use of multiple perspectives for problem solving. This analysis compared staff descriptions of the learning climate, use of social constructivist learning processes, and outcomes in nursing facilities receiving CONNECT with facilities receiving a falls education program alone.

DESIGN AND METHODS

Qualitative evaluation of a randomized controlled trial was done using a focus group design. Facilities (n = 8) were randomized to a falls education program alone (control) or CONNECT followed by FALLS (intervention). A total of 77 staff participated in 16 focus groups using a structured interview protocol. Transcripts were analyzed using framework analysis, and summaries for each domain were compared between intervention and control facilities.

RESULTS

Notable differences in descriptions of the learning climate included greater learner empowerment, appreciation of the role of all disciplines, and seeking diverse viewpoints in the intervention group. Greater use of social constructivist learning processes was evidenced by the intervention group as they described greater identification of communication weaknesses, improvement in communication frequency and quality, and use of sense-making by seeking out multiple perspectives to better understand and act on information. Intervention group participants reported outcomes including more creative fall prevention plans, a more respectful work environment, and improved relationships with coworkers. No substantial difference between groups was identified in safety culture, shared responsibility, and self-reported knowledge about falls.

IMPLICATIONS

CONNECT appears to enhance the use of social constructivist learning processes among nursing home staff. The impact of CONNECT on clinical outcomes requires further study.

An advanced course in long term care for geriatric medicine fellows

Long term care deserves focused attention within a geriatric medicine fellowship curriculum to ensure that graduates are prepared not only for clinical care but also for the leadership, administrative, educational, quality improvement, and health policy aspects of their future roles. This report describes the curriculum development and program evaluation of an advanced course in long term care for geriatric medicine fellows and other graduate/post-graduate health professionals at Duke University. Course evaluation had 4 goals: (1) to determine how well the learning objectives were met; (2) to evaluate individual components of the course to improve subsequent offerings; (3) to determine whether additional topics needed to be added; and (4) to evaluate the effectiveness of the discussion forum component of the course. Learner self-efficacy improved within all competency areas but especially those of practice-based learning and system-based practice. Evaluation results led to curriculum revision that has maintained course relevance and sustained it within the larger geriatrics fellowship curriculum. Components of this course can be easily adapted to other curricular settings for fellows and residents.

Memory deficit associated with worse functional trajectories in older adults in low-vision rehabilitation for macular disease

OBJECTIVES

To examine whether performance on a brief memory test is related to functional outcomes in older individuals undergoing low-vision rehabilitation (LVR) for macular disease.

DESIGN

Observational cohort study of individuals receiving outpatient LVR.

SETTING

Academic center.

PARTICIPANTS

Ninety-one individuals (average age 80.1) with macular disease.

MEASUREMENTS

Memory was assessed at baseline using a 10-word list; memory deficit was defined as immediate recall of two or fewer words. Vision-related function was measured using the 25-item Visual Function Questionnaire (VFQ-25) administered at baseline and during subsequent interviews (mean follow-up, 115 days). Linear mixed models were constructed to compare average trajectories of four VFQ-25 subscales: near activities, distance activities, dependency, and role difficulty.

RESULTS

The 29.7% of participants with memory deficits tended to decline in ability to accomplish activities that involved near vision. Controlling for age, sex, and education, the functional trajectory of participants with memory deficit differed significantly from that of those with better memory (P = .002), who tended to report improvements in ability to accomplish near activities.

CONCLUSION

Of older adults receiving LVR for macular disease, those with memory deficits experienced worse functional trajectories in their ability to perform specific visually mediated tasks. A brief memory screen may help explain variability in rehabilitation outcomes and identify individuals who might require special accommodations.

Staff interaction strategies that optimize delivery of transitional care in a skilled nursing facility: a multiple case study

After hospitalization, more than 1.5 million older adults each year receive postacute care in skilled nursing facilities (SNFs). Transitional care services, designed to prepare older SNF patients (and their family caregivers) for their transitions from an SNF to home, have rarely been studied. Thus, we conducted a longitudinal, multiple case study of transitional care provided in an SNF to explore the care processes and staff interaction strategies that SNF staff members used to optimize delivery of transitional care. Using qualitative data from 89 interviews, 118 field observations, and 70 chart, or document reviews, we observed that transitional care services were not solely formalized processes, but rather were embedded in the interactions among older adult patients, their family caregivers, and members of interdisciplinary care teams. We found, moreover, that staff member interactions with patients and family caregivers increased the capacity of patient care teams for optimizing patient-centered care, information exchange, and coordination of transitional care.

Health care utilization before and after an outpatient ED visit in older people

BACKGROUND

Older adults in the United States receive a significant amount of care in the emergency department (ED), yet the associations between ED and other types of health care utilization have not been adequately studied in this population.

OBJECTIVES

The goals of this study were to examine the relationships between health care use before and after an ED visit among older adults.

METHODS

This retrospective cohort study examined health care use among 308 patients 65 years or older discharged from a university-affiliated ED. Proportional-hazards models were used to assess the relationship between pre-ED health care use (primary care physician [PCP], specialist, ED, and hospital) and risk of return ED visits.

RESULTS

Older ED patients in this study had visited other types of providers frequently in the previous year (median number of PCP and specialist visits, 4). Patients who used the ED on 2 or more occasions in the previous year were found to have visited their PCP more often than those without frequent ED use (median number of visits, 7.0 vs 4.0; P < .001). Despite more PCP use in this population, frequent ED use was associated with increased risk of a repeat ED visit (hazard ratio, 2.20; 95% confidence interval, 1.15-4.21), in models adjusted for demographics and health status.

CONCLUSION

Older adults who use the ED are also receiving significant amounts of care from other sources; simply providing additional access to care may not improve outcomes for these vulnerable individuals.

Project LIFE: a partnership to increase physical activity in elders with multiple chronic illnesses

The authors describe a medical center-based randomized trial aimed at determining the feasibility and effectiveness of partnering patients and primary-care providers with an exercise health counselor. Study participants included 165 veterans age 70 years and older. The primary end point was change in physical activity at 3 and 6 months comparing patients receiving high-intensity physical activity counseling, attention control counseling, and usual care after receiving standardized clinic-based counseling. We noted a significant Group x Time interaction (p = .041) for physical activity frequency and a similar effect for caloric expenditure (p = .054). Participants receiving high-intensity counseling and usual care increased physical activity over the short term, but those with usual care returned to baseline by the end of the study. The intervention was well received by practitioners and patients. We conclude that partnering primary-care providers with specialized exercise counselors for age- and health-appropriate physical activity counseling is effective.

Translating evidence-based falls prevention into clinical practice in nursing facilities: Results and lessons from a quality improvement collaborative

OBJECTIVES

To describe the changes in process of care before and after an evidence-based fall reduction quality improvement collaborative in nursing facilities.

DESIGN

Natural experiment with nonparticipating facilities serving as controls.

SETTING

Community nursing homes.

PARTICIPANTS

Thirty-six participating and 353 nonparticipating nursing facilities in North Carolina.

INTERVENTION

Two in-person learning sessions, monthly teleconferences, and an e-mail discussion list over 9 months. The change package emphasized screening, labeling, and risk-factor reduction.

MEASUREMENTS

Compliance was measured using facility self-report and chart abstraction (n = 832) before and after the intervention. Fall rates as measured using the Minimum Data Set (MDS) were compared with those of nonparticipating facilities as an exploratory outcome.

RESULTS

Self-reported compliance with screening, labeling, and risk-factor reduction approached 100%. Chart abstraction revealed only modest improvements in screening (51% to 68%, P < .05), risk-factor reduction (4% to 7%, P = .30), and medication assessment (2% to 6%, P = .34). There was a significant increase in vitamin D prescriptions (40% to 48%, P=.03) and decrease in sedative-hypnotics (19% to 12%, P = .04) but no change in benzodiazepine, neuroleptic, or calcium use. No significant changes in proportions of fallers or fall rates were observed according to chart abstraction (28.6% to 37.5%, P = .17), MDS (18.2% to 15.4%, P = .56), or self-report (6.1-5.6 falls/1,000 bed days, P = .31).

CONCLUSION

Multiple-risk-factor reduction tasks are infrequently implemented, whereas screening tasks appear more easily modifiable in a real-world setting. Substantial differences between self-reported practice and medical record documentation require that additional data sources be used to assess the change-in-care processes resulting from quality improvement programs. Interventions to improve interdisciplinary collaboration need to be developed.

Functional Incidental Training: A Randomized, Controlled, Crossover Trial in Veterans Affairs Nursing Homes

OBJECTIVES

To test the effects of a rehabilitative intervention directed at continence, mobility, endurance, and strength (Functional Incidental Training (FIT)) in older patients in Department of Veterans Affairs (VA) nursing homes.

DESIGN

Randomized, controlled, crossover trial.

SETTING

Four VA nursing homes.

PARTICIPANTS

All 528 patients in the nursing homes were screened; 178 were eligible, and 107 were randomized to an immediate intervention group (Group 1; n=52) and a delayed intervention group (Group 2; n=55).

INTERVENTION

Trained research staff provided the FIT intervention, which included prompted voiding combined with individualized, functionally oriented endurance and strength-training exercises offered four times per day, 5 days per week, for 8 weeks. Group 1 received the intervention while Group 2 served as a control group; then Group 2 received the intervention while Group 1 crossed over to no intervention. A total of 64 subjects completed the intervention phase of the trial.

MEASUREMENTS

Timed measures of walking or wheeling a wheelchair (mobility), sit-to-stand exercises, independence in locomotion and toileting as assessed using the Functional Independence Measure (FIM), one-repetition maximum weight for several measures of upper and lower body strength, frequency of urine and stool incontinence, and appropriate toileting ratios.

RESULTS

There was a significant effect of the FIT intervention on virtually all measures of endurance, strength, and urinary incontinence but not on the FIM for locomotion or toileting. The effects of FIT were observed when Group 1 received the intervention and was compared with the control group and when Group 2 crossed over to the intervention. Group 1 deteriorated in all measures during the 8-week crossover period. Within-person comparisons also demonstrated significant effects on all measures in the 64 participants who completed the intervention; 43 (67%) of these participants were "responders" based on maintenance or improvement in at least one measure of endurance, strength, and urinary incontinence. No adverse events related to FIT occurred during the study period.

CONCLUSION

FIT improves endurance, strength, and urinary incontinence in older patients residing in VA nursing homes. Translating these positive benefits achieved under research conditions into practice will be challenging because of the implications of the intervention for staff workload and thereby the costs of care.

Functional Incidental Training: Applicability and feasibility in the Veterans Affairs nursing home patient population

OBJECTIVE

To examine the applicability and feasibility of an intervention directed at improving continence, endurance, and strength (Functional Incidental Training [FIT]), for older patients in Veterans Administration (VA) nursing homes.

DESIGN

Data were collected during a randomized, controlled, crossover trial.

SETTING

Four VA nursing homes.

PARTICIPANTS

All 528 patients in the nursing homes were screened, 178 were eligible, and 107 were randomized into the trial. A total of 64 participants completed the intervention phase of the trial.

INTERVENTION

Trained research staff provided the FIT intervention, which included prompted voiding combined with individualized, functionally oriented endurance and strength training exercises offered four times per day, 5 days per week, for 8 weeks.

MEASURES

Descriptive data were collected relevant to the translation of the FIT intervention into everyday practice, including number of patients eligible and reasons for ineligibility, attrition rates and reasons for attrition, participant adherence to and satisfaction with FIT, and the costs of FIT relative to usual care.

RESULTS

One third of the 528 patients met the eligibility criteria. The major reasons for ineligibility were being continent, age under 60, and a short anticipated length of stay. Of the 146 patients enrolled in the trial, 85 (58%) dropped out during the 9- to 10-month project. Deterioration in health status, death, and discharge accounted for two thirds of the attrition. Adherence to FIT was in general high but variable. Participants completed prompted voiding plus at least one exercise in 75% of the FIT rounds offered. Of the 60 participants who completed the protocol and who could answer simple questions, 75% indicated they enjoyed FIT, but 62% indicated that the exercise was too frequent, and 28% indicated they were offered opportunities to toilet too often. Based on timed observations, the costs of FIT are about four times as high as usual continence care.

CONCLUSIONS

FIT is applicable to a substantial number of patients in VA nursing homes. The FIT protocol tested in this trial can be further refined and individualized based on patient preferences and adherence to various components of FIT in order to make it more feasible, efficient, and cost-effective in practice. The costs of maintaining an intervention such as FIT in all VA nursing home patients who may benefit, however, are high and must be justified largely by potential positive effects on function and quality of life, as opposed to cost savings resulting from the intervention.

A randomized controlled trial of the psychosocial impact of providing internet training and access to older adults

The Internet (electronic mail and the World Wide Web) may provide new opportunities for communication that can help older adults avoid social isolation. This randomized controlled trial assessed the psychosocial impact of providing Internet access to older adults over a five-month period. One hundred volunteers from four congregate housing sites and two nursing facilities were randomly assigned to receive Internet training or to a wait list control group. The pre & post measures included the UCLA Loneliness scale, modified CES Depression scale, a measure of locus of control, computer attitudes, number of confidants, and overall quality of life. Participants received nine hours of small group training in six sessions over two weeks. Computers were available for continued use over five months and the trainer was available two hours/week for questions. At the end of the trial, 60% of the intervention group continued to use the Internet on a weekly basis. Although there was a trend toward decreased loneliness and depression in intervention subjects compared to controls, there were no statistically significant changes from baseline to the end of trial between groups. Among Internet users (n = 29) in the intervention group there were trends toward less loneliness, less depression, more positive attitudes toward computers, and more confidants than among intervention recipients who were not regular users (n = 19) of this technology. Most elderly participants in this trial learned to use the Internet and the majority continued to use it on a weekly basis. The psychosocial impact of Internet use in this sample suggested trends in a positive direction. Further research is needed to determine more precisely, which older adults, residing in which environmental contexts are more likely than others to benefit from this rapidly expanding information and communication link.

Pain in nursing home residents: an exploration of prevalence, staff perspectives, and practical aspects of measurement

OBJECTIVE

To help rectify the underdiagnosis of chronic pain in frail nursing home residents by developing a new feasible pain self-report instrument, the structured pain interview; to use this new tool to estimate pain prevalence and staff's knowledge of residents' pain in two nursing homes; and to compare the performance differences of the structured pain interview and the commonly used 0-10 scale.

DESIGN

Cross-sectional survey.

SETTING

One 120-bed VA-affiliated and one 125-bed university-affiliated, community-based nursing home in Durham, North Carolina.

PATIENTS

One hundred fifty-eight chronic care nursing home residents without aphasia, acute illness, persistent vegetative status, or severe hearing impairment and 3 1 nursing home nurses.

OUTCOME MEASURES

Pain prevalence according to resident self-report and nurse report; stability of response to the structured pain interview and 0-10 scale over 1 month; agreement between residents and nurses on the structured pain interview and 0-10 scale.

RESULTS

Fifty-eight percent of the VA and 45% of the community nursing home residents reported pain. Forty-two percent at the VA and 20% at the community home were unable to respond to the 0-10 scale, compared with 7.5% and 14% using the structured pain interview. Stability of response to the structured pain interview at 1 month was 0.56 at the VA (nurse-resident agreement 0.38) and 0.72 in the community (nurse-resident agreement 0.07), which was very comparable to the 0-10 scale.

CONCLUSIONS

We have developed a highly feasible tool for examining pain prevalence in nursing homes. This tool uncovered considerable miscommunication regarding pain between residents and staff. Improvement in pain communication between nursing home residents and staff is needed, so that more effective pain treatment programs can be developed for this vulnerable population.

Screening methods for thyroid hormone disruptors

The U.S. Congress has passed legislation requiring the EPA to implement screening tests for identifying endocrine-disrupting chemicals. A series of workshops was sponsored by the EPA, the Chemical Manufacturers Association, and the World Wildlife Fund; one workshop focused on screens for chemicals that alter thyroid hormone function and homeostasis. Participants at this meeting identified and examined methods to detect alterations in thyroid hormone synthesis, transport, and catabolism. In addition, some methods to detect chemicals that bind to the thyroid hormone receptors acting as either agonists or antagonists were also identified. Screening methods used in mammals as well as other vertebrate classes were examined. There was a general consensus that all known chemicals which interfere with thyroid hormone function and homeostasis act by either inhibiting synthesis, altering serum transport proteins, or by increasing catabolism of thyroid hormones. There are no direct data to support the assertion that certain environmental chemicals bind and activate the thyroid hormone receptors; further research is indicated. In light of this, screening methods should reflect known mechanisms of action. Most methods examined, albeit useful for mechanistic studies, were thought to be too specific and therefore would not be applicable for broad-based screening. Determination of serum thyroid hormone concentrations following chemical exposure in rodents was thought to be a reasonable initial screen. Concurrent histologic evaluation of the thyroid would strengthen this screen. Similar methods in teleosts may be useful as screens, but would require indicators of tissue production of thyroid hormones. The use of tadpole metamorphosis as a screen may also be useful; however, this method requires validation and standardization prior to use as a broad-based screen.

Pain measurement in elders with chronic low back pain: traditional and alternative approaches

Pain evaluation typically relies upon the use of self-report instruments. The validity of these tools is questionable in many older adults, however, particularly those with cognitive impairment. Rating of pain behavior (e.g. grimacing, sighing) by an objective observer represents an alternative pain assessment strategy which has been validated in subjects of heterogeneous ages. The purpose of this study was to examine, in a group of community-dwelling elderly with low back pain and lumbosacral osteoarthritis, the concurrent validity of observational pain behavior rating techniques as compared with self-report instruments and the degree to which pain and pain behavior relate to disability. Thirty-nine cognitively intact subjects, age > 65 years, without depression, other sources of pain, or other known spinal pathology underwent the following measures: (1) pain self-report using the verbal 0-10 scale, vertical verbal descriptor scale, Arthritis Impact Measurement Scales and McGill Pain Questionnaire; (2) pain behavior was sampled during two protocols, one, identical to that used by Keefe and Block (Behav. Ther., 13 (1982) 363-375), that required subjects to sit, stand, walk, and recline for 1-2 minute periods (which we have labelled the traditional protocol), and a second, more demanding protocol that was designed to simulate activities of daily living that place a premium on axial movement (the 'ADL' protocol); (3) disability was assessed using the Roland questionnaire, a 6 month global disability question and the Jette Functional Status Index; and (4) radiographic evaluation of the lumbosacral spine; osteoarthritis was quantitated using a previously validated scoring system. Interrelationships among pain, pain behavior and disability measures were tested using canonical correlations. Self-reported pain was associated with pain behavior frequency; the association was stronger when the ADL protocol was used, as compared with the traditional protocol. The association between pain and disability was modestly strong with both self-report instruments and pain behavior observation when the ADL protocol was used, but not when the traditional protocol was used. Our findings suggest that pain behavior observation is a valid assessment tool in the elderly. In addition, it seems that observation of elders during performance of activities of daily living may be a more sensitive and valid way of assessing pain behavior than observing pain behavior during sitting, walking, standing, or reclining.

The reliability, validity, and stability of a measure of physical activity in the elderly

OBJECTIVE

To assess the reliability, validity, and stability of an accelerometer-based monitor of physical activity in an elderly population.

DESIGN

Six studies were conducted to assess the Tritrac, a newly available accelerometer capable of storing three-dimensional activity data collected in minute epochs. After initial bench testing, the waist-worn devices were assessed for test-retest reliability during sitting and treadmill walking at 1mph and 2mph. Validity testing examined the Tritrac's ability to discriminate between different levels of physical activity and also compared the Tritrac with an established wrist-worn acclerometer, the Actigraph. Stability of the measure was examined over a period of 3 to 7 days, and in a subset of subjects this measurement was performed for a second week.

SETTING AND SUBJECTS

Residents of a VA Nursing Home (n = 40; mean age = 76), participants in an in-home nonaerobic exercise program (n = 36; mean age = 77), and community participants in an aerobic exercise program (n = 10; mean age = 71).

RESULTS

Intraclass correlation coefficients (ICC) for both the bench testing and test-retest reliability were .97. The device discriminated among subjects independently categorized as sedentary, moderately active, or active (F = 49.4, p = .0001) and between specific activities of varying intensity (F = 114.5, p = .0001). Tritrac and Actigraph measurement comparison showed a correlation of r = .77, p = .0001. Stability of the measure was demonstrated by ICCs = .81 and .78 for mean activity values and proportion of time spent in sedentary activity, respectively. No significant differences were observed when comparing activity measured for two separate weeks.

CONCLUSION

The Tritrac is a reliable and valid instrument producing activity measurement that was stable over time in the elderly population we studied. During our longitudinal testing, 20% of the subjects did not comply with wearing the device; this noncompliance issue must be considered in any use of the Tritrac.

Weight of the evidence on the human carcinogenicity of 2,4-D

The phenoxy herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is widely used to control the growth of weeds and broadleaf plants. We convened a panel of 13 scientists to weigh the evidence on the human carcinogenicity of 2,4-D. The panel based its findings on a review of the toxicological and epidemiological literature on 2,4-D and related phenoxy herbicides. The toxicological data do not provide a strong basis for predicting that 2,4-D is a human carcinogen. Although a cause-effect relationship is far from being established, the epidemiological evidence for an association between exposure to 2,4-D and non-Hodgkin's lymphoma is suggestive and requires further investigation. There is little evidence of an association between use of 2,4-D and soft-tissue sarcoma or Hodgkin's disease, and no evidence of an association between 2,4-D use and any other form of cancer. Scientists on the panel were asked to categorize 2,4-D as a "known," "probable," "possible," or "unlikely" carcinogen or as a noncarcinogen in humans. The predominant opinion among the panel members was that the weight of the evidence indicates that it is possible that exposure to 2,4-D can cause cancer in humans, although not all of the panelists believed the possibility was equally likely: one thought the possibility was strong, leaning toward probable, and five thought the possibility was remote, leaning toward unlikely. Two panelists believed it unlikely that 2,4-D can cause cancer in humans.
