Effects on health care use and associated cost of a home visiting program for older people with poor health status: a randomized clinical trial in the Netherlands

BACKGROUND: Home visiting programs have been developed to improve the functional abilities of older people and subsequently to reduce the use of institutional care services. The results of trials have been inconsistent and their cost-effectiveness uncertain. Home visits for a high-risk population rather than the general population seems a promising approach. We therefore studied the effects of a home visiting program for older people with poor health. This article describes the effects on health care use and associated cost. METHODS: We conducted a randomized clinical trial among 330 community-dwelling citizens, aged 70-84 years, in the Netherlands. Participants in the intervention group (n = 160) received eight home visits by a trained home nurse over an 18-month period; a multidimensional geriatric assessment of problems was included. The main outcomes are: admissions to hospital, nursing home, and home for older persons; contacts with medical specialists, general practitioners, and paramedics; and hours of home care help. The data on health care use were mostly obtained from computerized databases of various medical administration offices; the follow-up period was 24 months. RESULTS: Inpatient and outpatient health care use was similar for both groups, with the exception of a higher distribution of aids and in-home modifications in favor of the intervention group. No differences were found between the intervention and control group in health care cost. CONCLUSION: The home visiting program did not appear to have any effect on the health care use of older people with poor health and had a low chance of being cost-effective. We conclude that these visits are probably not beneficial for such persons within the health care setting in the Netherlands or comparable settings in other Western countries.     

Preventive home visits for community-dwelling frail elderly people based on Minimum Data Set-Home Care: Randomized controlled trial

Background:   Although preventive home visits for the elderly are mandatory in Japan, there has been little research into their effectiveness. The present study used the Minimum Data Set-Home Care (MDS-HC) as the basis for assessing community-dwelling frail elderly persons.
Methods:   The present study was a randomized controlled, community-based investigation of 368 elderly people aged 65 years and older who were dependent in the instrumental activities of daily living, but independent in activities of daily living. The participants were randomly assigned to an intervention group (184) or a control group (184). For 18 months, the intervention group received scheduled home visits by public health nurses who had been instructed that the primary objective of these visits was human interaction. The MDS-HC was used to assess the elderly person at each visit. The primary outcome was the EQ-5D score of the EuroQol and secondary outcomes were five items constituting the EQ-5D, self-rated health, and health behaviors. The types of advice given and subject compliance were also analyzed.
Results:   Intervention had no effect on the EQ-5D score, and positive results were limited to some aspects of health behavior. Subgroup analyses showed that the home visits were effective for elderly people who perceived their own health as poor at baseline, and for participants who complied with advice.
Conclusions:   The preventive home visits based on the MDS-HC were effective in selected groups of frail elderly people. Further modification in the use of the MDS-HC and more focused targeting are needed to make the visits more effective.     

Effect of preventive home visits for ambulatory housebound elders in Japan: a pilot study

BACKGROUND AND AIMS: Programs of preventive home visits for ambulatory housebound elders have not yet become established in Japan. The aim of this randomized pilot study was to investigate effects of such visits by public health nurses in Japan. METHODS: A randomized controlled study with 18-month follow-up was conducted in a small Japanese agricultural town. Participants (n=119) were ambulatory housebound elders aged 65 and over, who were able to walk but who went outdoors less than three times a week at baseline survey. They were randomly assigned to intervention (n=59) or control group (n=60). Intervention group subjects received preventive home visits by public health nurses over 18 months (mean home visits=4.3). Control group subjects received usual primary and community care. Activities of daily living (ADLs), functional capacity, self-efficacy for daily activities, self-efficacy for health promotion, depression, and social support were collected via questionnaire at baseline and at the 18-month follow-up point. RESULTS: At follow-up, 81.4% of intervention group subjects were still living at home vs 73.3% of control group subjects (NS). Simple group comparisons following repeated measures (ANCOVA) showed that the intervention group had higher ADL scores than the control group at follow-up (p=0.044). CONCLUSIONS: These pilot results suggest that home visits by public health nurses may be effective in helping to reduce ADL decline among ambulatory housebound elders.     

The effects of a targeted multicomponent delirium intervention on postdischarge outcomes for hospitalized older adults

PURPOSE: We sought to determine whether a multicomponent hospital-based intervention targeted toward risk factors for delirium had any effect on patient outcomes 6 months later. METHODS: We studied 705 patients aged 70 years or older who had been enrolled in a controlled trial of a multicomponent intervention at an academic medical center and who survived for at least 6 months after hospitalization. Outcomes included self-rated health, functional status, incontinence, depression, cognitive status, delirium, home health visits, homemaker visits, rehospitalization, and nursing home placement. RESULTS: Overall, there were no differences between the intervention and control groups for any of the 10 outcomes, except that incontinence was slightly less common in the intervention group (30% [103/344] vs. 37% [132/354], P = 0.02). Among high-risk patients, those in the intervention group had better self-rated health (among those with poor/bad self-rated health at baseline, P <0.001) and better functional status (among those with baseline functional impairment, P <0.001). There were no effects in the other six high-risk subgroups, including cognitive and behavioral outcomes (Folstein Mini-Mental State Examination, Geriatric Depression Scale, incontinence, and delirium) and health care utilization. CONCLUSION: In the group as a whole, we were unable to identify a lasting beneficial effect of the multicomponent intervention, although further efforts to identify appropriate subgroups for targeted interventions may be worthwhile. Other strategies are needed after hospital discharge to deter deterioration in susceptible elderly people.     

Community-based group exercise improves balance and reduces falls in at-risk older people: a randomised controlled trial

BACKGROUND: recent studies have found that moderate intensity exercise is an effective intervention strategy for preventing falls in older people. However, research is required to determine whether supervised group exercise programmes, conducted in community settings with at-risk older people referred by their health care practitioner are also effective in improving physical functioning and preventing falls in this group. OBJECTIVES: to determine whether participation in a weekly group exercise programme with ancillary home exercises over one year improves balance, muscle strength, reaction time, physical functioning, health status and prevents falls in at-risk community-dwelling older people. METHODS: the sample comprised 163 people aged over 65 years identified as at risk of falling using a standardised assessment screen by their general practitioner or hospital-based physiotherapist, residing in South Western Sydney, Australia. Subjects were randomised into either an exercise intervention group or a control group. Physical performance and general health measures were assessed at baseline and repeated 6-months into the trial. Falls were measured over a 12-month follow-up period using monthly postal surveys. RESULTS: at baseline both groups were well matched in their physical performance, health and activity levels. The intervention subjects attended a median of 23 exercise classes over the year, and most undertook the home exercise sessions at least weekly. At retest, the exercise group performed significantly better than the controls in three of six balance measures; postural sway on the floor with eyes open and eyes closed and coordinated stability. The groups did not differ at retest in measures of strength, reaction time and walking speed or on Short-Form 36, Physical Activity Scale for the Elderly or fear of falling scales. Within the 12-month trial period, the rate of falls in the intervention group was 40% lower than that of the control group (IRR=0.60, 95% CI 0.36-0.99). CONCLUSIONS: these findings indicate that participation in a weekly group exercise programme with ancillary home exercises can improve balance and reduce the rate of falling in at-risk community dwelling older people.     

A randomized trial of in-home visits for disability prevention in community-dwelling older people at low and high risk for nursing home admission

BACKGROUND: In-home preventive visits with multidimensional geriatric assessments can delay the onset of disabilities in older people. METHODS: This was a stratified randomized trial. There were 791 participants, community-dwelling people in Bern, Switzerland, older than 75 years. The participants' risk status was based on 6 baseline predictors of functional deterioration. The intervention consisted of annual multidimensional assessments and quarterly follow-up in-home visits by 3 public health nurses (nurses A, B, and C), who, in collaboration with geriatricians, evaluated problems, gave recommendations, facilitated adherence with recommendations, and provided health education. Each nurse was responsible for conducting the home visits in 1 ZIP code area. RESULTS: After 3 years, surviving participants at low baseline risk in the intervention group were less dependent in instrumental activities of daily living (ADL) compared with controls (odds ratio, 0.6; 95% confidence interval, 0.3-1.0; P = .04). Among subjects at high baseline risk, there were no favorable intervention effects on ADL and an unfavorable increase in nursing home admissions (P= .02). Despite the similar health status of subjects, nurse C identified fewer problems in the subjects who were visited compared with those assessed by nurses A and B. Subgroup analysis revealed that among low-risk subjects visited by nurses A and B, the intervention had favorable effects on instrumental ADL (P = .005) and basic ADL (P = .009), reduced nursing home admissions (P = .004), and resulted in net cost savings in the third year (US $1403 per person per year). Among low-risk subjects visited by nurse C, the intervention had no favorable effects. CONCLUSIONS: These data suggest that this intervention can reduce disabilities among elderly people at low risk but not among those at high risk for functional impairment, and that these effects are likely related to the home visitor's performance in conducting the visits.     

Effectiveness of a group outpatient visit model for chronically ill older health maintenance organization members: a 2-year randomized trial of the cooperative health care clinic

OBJECTIVES: To compare the effectiveness of Cooperative Health Care Clinic ((CHCC) group outpatient model for chronically ill, older health maintenance organization (HMO) patients) with usual care. DESIGN: Two-year, randomized, controlled trial conducted with recruitment from February 1995 through July of 1996. SETTING: Nonprofit group model HMO. PARTICIPANTS: Two hundred ninety-four adults (145 intervention and 149 usual care), aged 60 and older (mean age 74.1) with 11 or more outpatient visits in the prior 18 months, one or more self-reported chronic conditions, and expressed interest in participating in a group clinic. INTERVENTION: Monthly group meetings held by patients' primary care physicians. MEASUREMENT: Differences in clinic visits, inpatient admissions, emergency room visits, hospital outpatient services, professional services, home health, and skilled nursing facility admissions; measures of patient satisfaction, quality of life, self-efficacy, and activities of daily living (ADLs). RESULTS: Outpatient, pharmacy services, home health, and skilled nursing facility use did not differ between groups, but CHCC patients had fewer hospital admissions (P=.012), emergency visits (P=.008), and professional services (P=.005). CHCC patients' costs were $41.80 per member per month less than those of control patients. CHCC patients reported higher satisfaction with their primary care physician (P=.022), better quality of life (P=.002), and greater self-efficacy (P=.03). Health status and ADLs did not differ between groups. CONCLUSION: The CHCC model resulted in fewer hospitalizations and emergency visits, increased patient satisfaction, and self-efficacy, but no effect on outpatient use, health, or functional status.     

How do older patients and their GPs evaluate shared decision-making in healthcare?

Background

Physical activity shows potential in combating the poor outcomes associated with depression in older people. Meta-analyses show gaps in the research with poor trial design compromising certainty in conclusions and few programmes showing sustained effects.

Methods/design

The Depression in Late Life: an Intervention Trial of Exercise (DeLLITE) is a 12 month randomised controlled trial of a physical activity intervention to increase functional status in people aged 75 years and older with depressive symptoms. The intervention involves an individualised activity programme based on goal setting and progression of difficulty of activities delivered by a trained nurse during 8 home visits over 6 months. The control group received time matched home visits to discuss social contacts and networks. Baseline, 6 and 12 months measures were assessed in face to face visits with the primary outcome being functional status (SPPB, NEADL). Secondary outcomes include depressive symptoms (Geriatric Depression Scale), quality of life (SF-36), physical activity (AHS Physical Activity Questionnaire) and falls (self report).

Discussion

Due to report in 2008 the DeLLITE study has recruited 70% of those eligible and tests the efficacy of a home based, goal setting physical activity programme in improving function, mood and quality of life in older people with depressive symptomatology. If successful in improving function and mood this trial could prove for the first time that there are long term health benefit of physical activity, independent of social activity, in this high risk group who consume excess health related costs.

Effectiveness of a falls-and-fracture nurse coordinator to reduce falls: a randomized, controlled trial of at-risk older adults

OBJECTIVES: To assess the effectiveness of a community‐based falls‐and‐fracture nurse coordinator and multifactorial intervention in reducing falls in older people. DESIGN: Randomized, controlled trial. SETTING: Screening for previous falls in family practice followed by community‐based intervention. PARTICIPANTS: Three hundred twelve community‐living people aged 75 and older who had fallen in the previous year. INTERVENTION: Home‐based nurse assessment of falls‐and‐fracture risk factors and home hazards, referral to appropriate community interventions, and strength and balance exercise program. Control group received usual care and social visits. MEASUREMENTS: Primary outcome was rate of falls over 12 months. Secondary outcomes were muscle strength and balance, falls efficacy, activities of daily living, self‐reported physical activity level, and quality of life (Medical Outcomes Study 36‐item Short Form Questionnaire). RESULTS: Of the 3,434 older adults screened for falls, 312 (9%) from 19 family practices were enrolled and randomized. The average age was 81±5, and 69% (215/312) were women. The incidence rate ratio for falls for the intervention group compared with the control group was 0.96 (95% confidence interval=0.70–1.34). There were no significant differences in secondary outcomes between the two groups. CONCLUSION: This nurse‐led intervention was not effective in reducing falls in older people who had fallen previously. Implementation and adherence to the fall‐prevention measures was dependent on referral to other health professionals working in their usual clinical practice. This may have limited the effectiveness of the interventions.     

The internet-based arthritis self-management program: a one-year randomized trial for patients with arthritis or fibromyalgia

OBJECTIVE: To determine the efficacy of an Internet-based Arthritis Self-Management Program (ASMP) as a resource for arthritis patients unable or unwilling to attend small-group ASMPs, which have proven effective in changing health-related behaviors and improving health status measures. METHODS: Randomized intervention participants were compared with usual care controls at 6 months and 1 year using repeated-measures analyses of variance. Patients with rheumatoid arthritis, osteoarthritis, or fibromyalgia and Internet and e-mail access (n = 855) were randomized to an intervention (n = 433) or usual care control (n = 422) group. Measures included 6 health status variables (pain, fatigue, activity limitation, health distress, disability, and self-reported global health), 4 health behaviors (aerobic exercise, stretching and strengthening exercise, practice of stress management, and communication with physicians), 5 utilization variables (physician visits, emergency room visits, chiropractic visits, physical therapist visits, and nights in hospital), and self-efficacy. RESULTS: At 1 year, the intervention group significantly improved in 4 of 6 health status measures and self-efficacy. No significant differences in health behaviors or health care utilization were found. CONCLUSION: The Internet-based ASMP proved effective in improving health status measures at 1 year and is a viable alternative to the small-group ASMP.     

Fewer Emergency Readmissions and Better Quality of Life for Older Adults at Risk of Hospital Readmission: A Randomized Controlled Trial to Determine the Effectiveness of a 24-Week Exercise and Telephone Follow-Up Program

OBJECTIVES: To evaluate the effect of an exercise‐based model of hospital and in‐home follow‐up care for older people at risk of hospital readmission on emergency health service utilization and quality of life. DESIGN: Randomized controlled trial. SETTING: Tertiary metropolitan hospital in Australia. PARTICIPANTS: One hundred twenty‐eight patients (64 intervention, 64 control) with an acute medical admission, aged 65 and older and with at least one risk factor for readmission (multiple comorbidities, impaired functionality, aged ≥75, recent multiple admissions, poor social support, history of depression). INTERVENTION: Comprehensive nursing and physiotherapy assessment and individualized program of exercise strategies and nurse‐conducted home visit and telephone follow‐up commencing in the hospital and continuing for 24 weeks after discharge. MEASUREMENTS: Emergency health service utilization (emergency hospital readmissions and visits to emergency department, general practitioner (GP), or allied health professional) and health‐related quality of life (Medical Outcomes Study 12‐item Short Form Survey (SF‐12v2^?) collected at baseline and 4, 12, and 24 weeks after discharge. RESULTS: The intervention group required significantly fewer emergency hospital readmissions (22% of intervention group, 47% of control group, P=.007) and emergency GP visits (25% of intervention group, 67% of control group, P<.001). The intervention group also reported significantly greater improvements in quality of life than the control group as measured using SF‐12v2^? Physical Component Summary scores (F (3, 279)=30.43, P<.001) and Mental Component Summary scores (F (3, 279)=7.20, P<.001). CONCLUSION: Early introduction of an individualized exercise program and long‐term telephone follow‐up may reduce emergency health service utilization and improve quality of life of older adults at risk of hospital readmission.     

Home visits by an occupational therapist for assessment and modification of environmental hazards: a randomized trial of falls prevention

OBJECTIVE: To determine whether occupational therapist home visits targeted at environmental hazards reduce the risk of falls. DESIGN: A randomized controlled trial. SETTING: Private dwellings in the community in Sydney, Australia. PARTICIPANTS: A total of 530 subjects (mean age 77 years), recruited primarily before discharge from selected hospital wards. INTERVENTION: A home visit by an experienced occupational therapist, who assessed the home for environmental hazards and facilitated any necessary home modifications. MEASUREMENTS: The primary study outcome was falls, ascertained over a 12-month follow-up period using a monthly falls calendar. RESULTS: Thirty six percent of subjects in the intervention group had at least one fall during follow-up, compared with 45% of controls (P = .050). The intervention was effective only among subjects (n = 206) who reported having had one or more falls during the year before recruitment into the study; in this group, the relative risk of at least one fall during follow-up was 0.64 (95% confidence interval, 0.50-0.83). Similar results were obtained when falls data were analyzed using survival analysis techniques (proportional and multiplicative hazards models) and fall rates (mean number of falls per person per year). About 50% of the recommended home modifications were in place at a 12-month follow-up visit. CONCLUSIONS: Home visits by occupational therapists can prevent falls among older people who are at increased risk of falling. However, the effect may not be caused by home modifications alone. Home visits by occupational therapists may also lead to changes in behavior that enable older people to live more safely in both the home and the external environment.     

A Cluster-Randomized Trial of an Educational Intervention to Reduce the Use of Physical Restraints with Psychogeriatric Nursing Home Residents

OBJECTIVES: To investigate the effects of an educational intervention on the use of physical restraints with psychogeriatric nursing home residents.
DESIGN: Cluster-randomized trial.
SETTING: Fifteen psychogeriatric nursing home wards in the Netherlands.
PARTICIPANTS: In total, 432 psychogeriatric nursing home residents from 15 psychogeriatric nursing home wards in seven nursing homes were selected for participation; 404 consented, and 371 of these were available at baseline. Two hundred forty-one from 14 wards had complete data and were included in the data analyses.
INTERVENTION: The nursing home wards were assigned at random to educational intervention or control status. The educational intervention consisted of an educational program for nursing staff combined with consultation with a nurse specialist (registered nurse (RN) level).
MEASUREMENTS: Data were collected at baseline and 1, 4, and 8 months postintervention. At each measurement, the use of physical restraints was measured using observations of blinded, trained observers on four separate occasions over a 24-hour period. Other resident characteristics, such as cognitive status, were determined using the Minimum Data Set.
RESULTS: Logistic and linear regression analyses showed no treatment effect on restraint status, restraint intensity, or multiple restraint use in any of the three postintervention measurements. Furthermore, only small changes occurred in the types of restraints used with residents in the experimental group.
CONCLUSION: An educational program for nursing staff combined with consultation with a nurse specialist (RN level) had no effect on the use of physical restraints with psychogeriatric nursing home residents. In addition to restraint education and consultation, new measures to reduce the use of physical restraints with psychogeriatric nursing home residents should be developed.     

The effect of oral health on quality of life in an underprivileged homebound and non-homebound elderly population in Jerusalem

OBJECTIVES: To measure the effect of oral health on quality of life in elderly people in Jerusalem and to compare homebound and nonhomebound people.
DESIGN: A cross-sectional, purposive cluster sample.
SETTING: Community-based, one dental clinic, three geriatric day centers, and home visits.
PARTICIPANTS: Three hundred forty-four underprivileged people aged 60 and older, 64 of whom were homebound.
MEASUREMENTS: Score on the shortened version of the Oral Health Impact Profile (OHIP-14) (validated for Hebrew) was the dependent variable. One dental assistant conducted a structured interview, including universal variables, and one dentist examined dental status.
RESULTS: Average OHIP-14 level was 10.43. For total OHIP-14, the odds ratio comparing the homebound with the nonhomebound population was 2.06 ( P =.03). After multiple logistic regression, functional ability and education level reached independent significance for OHIP-14 level were.
CONCLUSION: Homebound elderly people reported greater difficulties than nonhomebound people in communication, eating, relaxation, and life satisfaction as related to oral health.     

Improving medication use in newly admitted home healthcare patients: a randomized controlled trial

OBJECTIVES: To test the efficacy of a medication use improvement program developed specifically for home health agencies. The program addressed four medication problems identified by an expert panel: unnecessary therapeutic duplication, cardiovascular medication problems, use of psychotropic drugs in patients with possible adverse psychomotor or adrenergic effects, and use of nonsteroidal antiinflammatory drugs (NSAIDs) in patients at high risk of peptic ulcer complications. It used a structured collaboration between a specially trained clinical pharmacist and the patients' home-care nurses to improve medication use. DESIGN: Parallel-group, randomized controlled trial. SETTING: Two of the largest home health agencies in the United States. PARTICIPANTS: Study subjects were consenting Medicare patients aged 65 and older admitted to participating agency offices from October 1996 through September 1998, with a projected home healthcare duration of at least 4 weeks and at least one study medication problem. INTERVENTION: Qualifying patients were randomized to usual care or usual care with the medication improvement program. MEASUREMENTS: Medication use was measured during an in-home interview, with container inspection at baseline and at follow-up (between 6 and 12 weeks) by interviewers unaware of treatment assignment. The trial endpoint was the proportion of patients with medication use improvement according to predefined criteria at follow-up. RESULTS: There were 259 randomized patients with completed follow-up interviews: 130 in the intervention group and 129 with usual care. Medication use improved for 50% of intervention patients and 38% of control patients, an attributable improvement of 12 patients per 100 (95% confidence interval (CI) = 0.0-24.0, P =.051). The intervention effect was greatest for therapeutic duplication, with improvement for 71% of intervention and 24% of control patients, an attributable improvement of 47 patients per 100 (95% CI = 20-74, P =.003). Use of cardiovascular medications also improved more frequently in intervention patients: 55% vs 18%, attributable improvement 37 patients per 100 (95% CI = 9-66, P =.017). There were no significant improvements for the psychotropic medication or NSAID problems. There was no evidence of adverse intervention effects: new medication problems, more agency nurse visits, or increased duration of home health care. CONCLUSIONS: A program congruent with existing personnel and practices of home health agencies improved medication use in a vulnerable population and was particularly effective in reducing therapeutic duplication.     

Long-Term Effect on Mortality of a Home Intervention that Reduces Functional Difficulties in Older Adults: Results from a Randomized Trial

OBJECTIVES: To evaluate the long-term mortality effect of a home-based intervention previously shown to reduce functional difficulties and whether survivorship benefits differ according to initial mortality risk level.
DESIGN: Two-group randomized trial with survivorship followed up to 4 years from study entry.
SETTING: Homes of urban community-living elderly people.
PARTICIPANTS: Three hundred nineteen adults aged 70 and older with difficulties performing daily activities.
INTERVENTION: Occupational and physical therapy sessions to instruct participants in compensatory strategies, home modifications, home safety, fall recovery techniques, and balance and muscle strength exercises.
MEASUREMENTS: Survival time was number of days between baseline interview and date of death, as determined using data from the National Death Index or December 31, 2005. Participants were stratified according to baseline mortality risk (low, moderate, high) using a prognostic indicator.
RESULTS: At 2 years, intervention participants (n=160) had a 5.6% mortality rate (n=9 deaths) and controls (n=159) a 13.2% rate (n=21 deaths; P =.02). Mortality rates remained lower for intervention participants up to 3.5 years from study entry. At 2 years, intervention participants with moderate mortality risk had a 16.7% mortality rate (n=16 deaths/96), compared with 28.2% for equivalent control group participants (n=24 deaths/85; P =.02). By 3 years, mortality rates were not statistically significantly different between the experimental and control groups.
CONCLUSIONS: The intervention extended survivorship up to 3.5 years and maintained statistically significant differences for 2 years. Subjects at moderate mortality risk derived the most intervention benefit. Findings suggest that the intervention could be a low-cost clinical tool to delay functional decline and mortality.     

Does investment in home visitors lead to better psychological health for HIV-affected families? Results from a quasi-experimental evaluation in South Africa

Children and families affected by HIV are at considerable risk for psychological distress. Community-based home visiting is a common mechanism for providing basic counseling and other services to HIV-affected families. While programs emphasize home visitor training and compensation as means to promote high-quality service delivery, whether these efforts result in measurable gains in beneficiaries' well-being remains largely unanswered. This study employs a longitudinal quasi-experimental design to explore whether these kinds of investments yield concomitant gains in psychological outcomes among beneficiaries. Baseline and follow-up data were collected over a two-year period from children aged 10–17 at the time of program enrollment and their caregivers, with 80% retention. In this sample of 1487 children and 918 caregivers, the psychological health outcomes of those enrolled in programs with home visitors who receive intensive training, organizational support, and regular compensation (termed “paraprofessional”) were compared to those enrolled in programs offering limited home visiting services from lay volunteers. Applying multilevel logistic regression, no measurable improvements were found among paraprofessional enrollees, and three outcomes were significantly worse at follow-up regardless of program model. Children's behavior problems became more prevalent even after adjusting for other factors, increasing from 29% to 35% in girls and from 28% to 43% in boys. Nearly one-quarter of girl and boys reported high levels of depression at follow-up, and this was a significant rise over time for boys. Rates of poor family functioning also significantly worsened over time, rising from 30% to 59%. About one-third of caregivers reported high levels of negative feelings at follow-up, with no improvements observed in the paraprofessional group. Results highlight that children's and caregivers' psychological outcomes may be relatively impervious to change even in paraprofessional home visiting models. Findings underscore the need for programs serving HIV-affected families to add focused evidence-based psychological interventions to supplement traditional home visiting.     

Lack of Effect of Tai Chi Chuan in Preventing Falls in Elderly People Living at Home: A Randomized Clinical Trial

OBJECTIVES: To evaluate the effectiveness of Tai Chi Chuan in fall prevention in elderly people living at home with a high risk of falling.
DESIGN: Randomized controlled trial.
SETTING: Two industrial towns in the western part of the Netherlands.
PARTICIPANTS: Two hundred sixty-nine elderly people (average age 77) living at home with a high risk of falling.
INTERVENTIONS: The intervention group received Tai Chi Chuan training for 1 hour twice a week for 13 weeks; the control group received usual care. Both groups received a brochure containing general information on how to prevent fall incidents.
MEASUREMENTS: Primary outcome was the number of falls over 12 months. Secondary outcomes were balance, fear of falling, blood pressure, heart rate at rest, forced expiratory volume during the first second, peak expiratory flow, physical activity, and functional status.
RESULTS: After 12 months, no lower fall risk in the Tai Chi Chuan group was observed than in the control group (adjusted hazard ratio=1.16; 95% confidence interval=0.84–1.60), and there were no significant intervention effects on the secondary outcome measures.
CONCLUSION: These results suggest that Tai Chi Chuan may not be effective in elderly people at a high risk of falling who live at home.     

Feeling better? Trends in general health status

OBJECTIVES: We addressed three questions: Have recent improvements in old-age disability been mirrored in changes in self-reported general health status? Are general health status trends similar for younger and older Americans? Have changes in general health status been uniform across demographic and socioeconomic groups? METHODS: Using logistic regression, we analyzed data from the 1982-2003 National Health Interview Surveys (n = 1,445,872 aged 18-69; n = 178,384 aged 70 and older). RESULTS: The proportion of people aged 70 and older reporting disability declined at 1.38% per year and the proportion 70 and older reporting poor/fair health declined at 1.85% per year. There was less of a decline in reports of poor/fair health at younger ages. Trends for the 18-69 population showed widening health disparities by income but narrowing of the race/ethnicity and education gaps. In the older population, there was no change for those aged 80-84 and 85 and older, the race/ethnicity gap persisted, and both education and income differentials widened over time. DISCUSSION: Declines in proportions reporting poor/fair health among the older population in recent decades mirror declines in disability. Although the younger population has not experienced such progress, its prevalence of poor/fair health is low throughout the 21-year analysis period. Of concern are the growing socioeconomic disparities in health for both younger and older populations.     

Brief Intervention for Problem Drinkers in a Chinese Population: A Randomized Controlled Trial in a Hospital Setting

Background:  Alcohol is a legal and accessible substance in Taiwan. As excessive alcohol has been linked to health and social problems, it is necessary to develop a brief, rapid, and low-cost tool to help health care providers deal with persons in Taiwan whose alcohol consumption has become hazardous or harmful to their health.
Methods:  A randomized controlled clinical trial with 6- and 12-month follow-ups was designed. Eighteen medical/surgical units at a medical center in northern Taiwan were randomly assigned to 2 groups: experimental ( n  = 9) and control ( n  = 9). Inpatients on the units were enrolled if they met the following criteria: were older than 18 years, had no severe psychiatric illness, and were not pregnant. The experimental group ( n  = 138) received the intervention, a 15-minute counseling visit in which nurses screened participants using the Alcohol Use Disorders Identification Test (AUDIT), provided a health promotion booklet for adults, and individually discussed the booklet contents with patients based on their drinking level (AUDIT score). The control group ( n  = 137) received no treatment. Patterns of alcohol consumption were determined by AUDIT scores at baseline, 6, and 12 months later.
Results:  Alcohol use disorders identification test scores decreased significantly in both groups at 6 months after the intervention, but did not differ significantly between the 2 groups. However, 12 months after the brief alcohol intervention, experimental subjects' AUDIT scores were significantly better than those of the control group.
Conclusions:  Our brief alcohol intervention provided a 12-month benefit for problem drinkers in Taiwan.
