Underlying diagnosis predicts patient-reported outcomes after revision total knee arthroplasty

To assess the association of underlying diagnosis with outcomes after revision total knee arthroplasty (TKA). For this cohort study we used prospectively collected data from the Mayo Clinic Total Joint Registry on all revision TKA patients from 1993 to 2005 with 2- or 5-year response to a validated knee questionnaire that assesses pain and function. We used logistic regression to assess the odds of moderate-severe activities of daily living (ADL) limitations and moderate-severe index knee pain 2 and 5 years after revision TKA. Odds ratios (ORs) and 95% CIs are presented. The underlying diagnosis for the 2- and 5-year cohorts was loosening, wear or osteolysis in 73% and 75%; dislocation, bone or prosthesis fracture, instability or non-union in 17% and 15%; and failed prior arthroplasty with components removed or infection in 11% and 11%, respectively. In multivariable adjusted analyses that included preoperative status, compared with patients with loosening/wear/osteolysis, patients with dislocation/fracture/instability/non-union had an OR of 2.1 for moderate-severe ADL limitation (95% CI 1.3, 3.1, P < 0.001) and those with failed prior arthroplasty/infection had an OR of 1.1 (95% CI 0.6, 1.8, P = 0.4). At 5 years, differences were no longer significant. In multivariable adjusted analyses, compared with patients with loosening/wear/osteolysis, patients with dislocation/fracture/instability/non-union had an OR of 2.0 for moderate-severe pain (95% CI 1.3, 3.1, P < 0.01) at 2 years and an OR of 2.1 (95% CI 1.3, 3.8, P = 0.01) at 5 years. Failed prior arthroplasty/infection was not significantly different than the reference category. Underlying diagnosis is independently associated with ADL limitations and pain after revision TKA. This information can help patients have realistic expectations of outcomes.

Trends in disability and related chronic conditions among the forty-and-over population: 1997–2010

BackgroundDownward trends in activity limitations among the older U.S. population have recently plateaued, while activity limitation among the pre-retirement population has increased. ObjectivesUpdate temporal trends in limitations in sensory and physical functions, instrumental activities of daily living (IADLs), and activities of daily living (ADLs) for the 40–64 and 65-and-over U.S. populations; assess the extent to which trends in education, smoking, and obesity could account for the trends in limitations; and examine trends in conditions cited as causes of limitations, their durations, and proportion of life spent with them. MethodsMultivariate analysis of the 1997–2010 National Health Interview Survey. ResultsFor the younger group, there have been increases in all limitations, except trouble hearing, which has declined. Increased obesity could account for the increases in vision, physical function, and IADL limitations. Musculoskeletal conditions, such as arthritis and back/neck problems, are frequently cited as causes of limitation, and there are growing roles for depression and nervous system conditions.For the 65-and-over group, there have been decreases in all limitations, except difficulty with physical functions, which is up. Increased education could account for the decline in ADL limitation, and increased obesity could account for increased difficulty with physical functions. Musculoskeletal conditions are also frequently cited as causes of limitation, but declines in heart- and vision-related limitations have been important. ConclusionTrends should continue to be monitored closely for both groups, since younger people have not experienced the improvements of the older group, but are its future members.

Health Impacts of Caregiving for Older Adults With Functional Limitations

To estimate the health impact, in terms of depression, self-rated health, and health services utilization, of providing care to older adults (75+) requiring human assistance in at least one activity of daily living (ADL) limitation. Data from 1,077 caregivers and 318 noncaregivers, interviewed in the Singapore Survey on Informal Caregiving, was used to examine differences in depressive symptoms, self-rated health, and number of outpatient visits in the last 1 month between caregivers and noncaregivers. Multivariate models for the outcomes, adjusting for characteristics of the caregiver/noncaregiver and care-recipient/potential care recipient, were run. Caregivers were more depressed, had poorer self-rated health, and had a higher rate of outpatient visits in the past month compared to noncaregivers. The study indicates the need for support services to family caregivers of older adults with ADL limitations.

Operative diagnosis for revision total hip arthroplasty is associated with patient-reported outcomes (PROs).

BackgroundLittle is known about the impact of the reason for revision total hip arthroplasty (THA) on the outcomes following revision THA. In this study, our objective was to assess the association of operative diagnosis with patient-reported outcomes (PROs) after revision THA.MethodsWe used prospectively collected data from the Mayo Clinic Total Joint Registry that collects pre- and post-operative pain and function outcomes using a validated Hip questionnaire, on all revision THAs from 1993–2005. We used logistic regression to assess the odds of moderate-severe index hip pain and moderate-severe limitation in activities of daily living (ADLs) 2- and 5-years after revision THA. We calculated odds ratios (OR) and 95% confidence intervals (CIs).ResultsFor the 2- and 5-year cohorts, the operative diagnosis was loosening/wear/osteolysis in 73% and 75%; dislocation/bone or prosthesis fracture/instability or non-union in 17% and 15%; and failed prior arthroplasty with components removed/infection in 11% and 11%, respectively. In multivariable-adjusted analyses that included preoperative ADL limitations, compared to patients with loosening/wear/osteolysis, patients with dislocation/fracture/instability/non-union had OR of 2.2 (95% CI, 1.3-3.5; p = 0.002) for overall moderate-severe ADL limitation and those with failed prior arthroplasty/infection had OR of 1.6 (95% CI, 1.0-2.8; p = 0.06). At 5-years, ORs were lower and differences were no longer significant. Moderate-severe pain did not differ significantly by diagnosis, at 2- or 5-years in multivariable adjusted analyses, with one exception, i.e. failed prior arthroplasty/infection had a trend towards significance with odds ratio of 1.9 (95% CI, 0.9-3.8; p = 0.07).ConclusionsOperative diagnosis is independently associated with ADL limitations, but not pain, at 2-years after revision THA. Patients should be informed of the risk of poorer short-term outcomes based on their diagnosis.

Stroke‐Associated Differences in Rates of Activity of Daily Living Loss Emerge Years Before Stroke Onset

To compare typical age-related changes in activities of daily living (ADLs) independence in stroke-free adults with long-term ADL trajectories before and after stroke. Prospective, observational study. Community-dwelling Health and Retirement Study (HRS) cohort. HRS participants who were stroke free in 1998 and were followed through 2008 (average follow-up 7.9 years) (N = 18,441). Strokes were assessed using self- or proxy-report of a doctor's diagnosis and month and year of event. Logistic regression was used to compare within-person changes in odds of self-reported independence in five ADLs in those who remained stroke free throughout follow-up (n = 16,816), those who survived a stroke (n = 1,208), and those who had a stroke and did not survive to participate in another interview (n = 417). Models were adjusted for demographic and socioeconomic covariates. Even before stroke, those who later developed stroke had significantly lower ADL independence and were experiencing faster independence losses than similar-aged individuals who remained stroke free. Of those who developed a stroke, survivors experienced slower pre-stroke loss of ADL independence than those who died. ADL independence declined at the time of stroke and decline continued afterwards. In adults at risk of stroke, disproportionate ADL limitations emerge well before stroke onset. Excess disability in stroke survivors should not be entirely attributed to effects of acute stroke or quality of acute stroke care. Although there are many possible causal pathways between ADL and stroke, the association may be noncausal. For example, ADL limitations may be a consequence of stroke risk factors (e.g., diabetes mellitus) or early cerebrovascular ischemia.

Comparison of Activities of Daily Living Ability of Older Adults Who Are Homebound and Nonhomebound

ABSTRACTThe objective of this study was to compare the activities of daily living (ADL) ability of older adults who were chronically homebound to older adults who were nonhomebound.The participants were 40 older adults 60 years of age or older, 20 homebound and 20 nonhomebound. The two groups did not differ in mean age, gender distribution, ethnicity, marital status, living situation, or type of housing. The older adults who were homebound had significantly more conditions than those who were nonhomebound.T tests revealed statically significant differences in the mean Assessment of Motor and Process Skills ADL motor and ADL process ability measures of older adults in the homebound and nonhomebound groups, with the latter group demonstrating higher ADL ability measures. Based on a power analysis indicating a need for 10 persons in each group, the nonhomebound group was subsequently divided into two subgroups, those who needed assistance to perform ADL from paid staff and/or family members and those who performed ADL independently. The results of two analyses of variance revealed that participants who were chronically homebound and those who were nonhomebound and had assistance had significantly lower ADL motor ability and ADL process ability than those who were nonhomebound and independent. The homebound group and the nonhomebound group with assistance did not differ significantly in ADL motor or ADL ability.The findings support the need for occupational therapists to provide services for older adults who have ADL limitations regardless of their homebound status.

Ethnic Disparities in Disability Among Middle-Aged and Older Israeli Adults

We examined the contribution of socioeconomic disadvantage and traumatic life events to ethnic disparities in disability among Israeli adults. We used data from the Survey of Health, Aging and Retirement in Europe (SHARE-Israel), a sample of Israeli adults aged 50 or older (N = 1,546). Disability measures included functional limitations, limitations in activities of daily living (ADL), and limitations in instrumental activities of daily living (IADL). Arabs and immigrants from the Former Soviet Union (FSU) experienced higher rates of functional limitations and limitations in IADLs compared to veteran Jews. The rate of having limitations in ADLs was similar for Arabs and veteran Jews, but was higher for FSU immigrants compared to veteran Jews. Inclusion of education, income, and traumatic life events attenuated, but did not eliminate ethnic disparities in disability. Identifying factors driving ethnic health disparities in Israel is imperative if we hope to achieve health equity.

Prognosis for Functional Deterioration and Functional Improvement in Late Life Among Community-Dwelling Persons

To examine how health-related, socioeconomic, and environmental factors combine to influence the onset of activity of daily living (ADL) limitations or prognosis for death or further functional deterioration or improvement among elderly people. A national representative sample with 2-year follow-up. Community-dwelling people. Included were 9447 persons (≥70 years of age) in the United States from the Second Longitudinal Study of Aging who were interviewed in 1994, 1995, or 1996. Self- or proxy-reported health conditions, ADLs expressed as 5 stages describing severity and pattern of limitations, and other baseline characteristics were obtained. A multinomial logistic regression model was used to predict stage transitions. Because of incomplete follow-up (17.7% of baseline sample), primary analyses were determined by multiple imputation to address potential bias associated with loss to follow-up. ADL stage transitions in 2 years (death, deteriorated, stable, and improved ADL function). In the imputed-case analysis, the percentages for those who died, deteriorated, were stable, and improved were 12.6%, 32.7%, 48.4%, and 6.2%, respectively. Persons at a mild stage of ADL limitation were most likely to deteriorate further. Persons at advanced stages were most likely to die. Married people and high school graduates had a lower likelihood of deterioration. The risk of mortality and functional deterioration increased with age. Certain conditions, such as diabetes, were associated both with mortality and functional deterioration; other conditions, such as cancer, were associated with mortality only, and arthritis was associated only with functional deterioration. Although overlap occurs, different clinical traits are associated with mortality, functional deterioration, and functional improvement. ADL stages might aid physical medicine and rehabilitation clinicians and researchers in developing and monitoring disability management strategies targeted to maintaining and enhancing self-care among community-dwelling older people.

Patient-level clinically meaningful improvements in activities of daily living and pain after total hip arthroplasty: data from a large US institutional registry

To characterize patient-level clinically meaningful improvements in pain and limitation of key activities of daily living (ADLs) after primary or revision total hip arthroplasty (THA). We analysed prospectively collected data from the Mayo Clinic Total Joint Registry to study clinically meaningful improvements in index hip pain severity and limitation in seven key ADLs (walking, climbing stairs, putting on shoes/socks, picking up objects, getting in/out of car, rising from a chair and sitting), from preoperative to 2- and 5-year post-THA. The primary THA cohort consisted of 6168 responders preoperatively, 5707 at 2 years and 3289 at 5 years postoperatively. The revision THA cohort consisted of 2063 responders preoperatively, 2682 at 2 years and 1627 at 5 years postoperatively. In the primary THA cohort, clinically meaningful pain reduction to mild or no hip pain at 2 years was reported by 94% with moderate and 91% with severe preoperative pain; respective proportions were 91% and 89% at 5-year follow-up. For revision THA, respective proportions were 84% and 77% at 2 years and 80% and 78% at 5 years. In the primary THA cohort, up to 4% with moderate and 17% with severe preoperative ADL limitation reported severe limitation in the respective activity 2 years post-primary THA; at 5 years, the respective proportions were up to 7% and 20%. Respective proportions for revision THA were up to 10% and 26% at 2 years and 13% and 30% at 5 years. These comprehensive data for patient-level clinically meaningful improvements in pain and seven key ADLs can help patients set realistic goals for improvement after THA.

Simulating the Impact of Long‐Term Care Policy on Family Eldercare Hours

To understand the effect of current and future long-term care (LTC) policies on family eldercare hours for older adults (60years of age and older) in Singapore. The Social Isolation Health and Lifestyles Survey, the Survey on Informal Caregiving, and the Singapore Government's Ministry of Health and Department of Statistics. An LTC Model was created using system dynamics methodology and parameterized using available reports and data as well as informal consultation with LTC experts. In the absence of policy change, among the elderly living at home with limitations in their activities of daily living (ADLs), the proportion of those with greater ADL limitations will increase. In addition, by 2030, average family eldercare hours per week are projected to increase by 41 percent from 29 to 41hours. All policy levers considered would moderate or significantly reduce family eldercare hours. System dynamics modeling was useful in providing policy makers with an overview of the levers available to them and in demonstrating the interdependence of policies and system components.

The Impact of Body Mass Index and Weight Changes on Disability Transitions and Mortality in Brazilian Older Adults

The aim of this study was to examine the association between body mass index and weight changes on disability transitions and mortality among Brazilian older adults. Longitudinal data from the Health, Well-Being, and Aging in Latin America and the Caribbean Study conducted in São Paulo, Brazil (2000 and 2006), were used to examine the impact of obesity on disability and mortality and of weight changes on health transitions related to disability. Logistic and multinomial regression models were used in the analyses. Individuals who were obese were more likely than those of normal weight to have limitations on activities of daily living (ADL), instrumental activity of daily living (IADL), and Nagi's limitations. Obesity was associated with higher incidence of ADL and IADL limitations and with lower recovery from Nagi's limitations. Compared to those who maintained their weight, those who gained weight experienced higher incidence of ADL and Nagi's limitations, even after controlling for initial body mass index. Higher mortality among overweight individuals was only found when the reference category was “remaining free of Nagi limitations.” The findings of the study underline the importance of maintaining normal weight for preventing disability at older ages.

2600 – Getting to the ‘heart’ of the matter: gender specificities in acute coronary syndromes

More than one in five women die from ischemic heart disease (IHD) and given their longer life expectancy, these numbers are expected to rise and so is the concomitant disability burden. Women are still under-represented in cardiovascular research with much of the knowledge from clinical trials conducted largely with men being applied to women, disregarding potential gender differences in both biomedical and psychosocial domains. Gender differences in both pathophysiology and biological risk factors may underlie distinct prevalence rates, symptom profiles and even medical outcomes. Not only do women have more persistent and atypical symptoms, but have more frequent hospitalizations, lower rates of general well-being and increased functional limitations in daily life activities. Gender related specificities regarding psychosocial risk factors might further explain this. The authors review the key issues on this topic and outline suggestions for future research. Ultimately, a better understanding of this matter will translate not only into improved clinical management of female patients but also genderspecific strategies in the prevention of CVD.

Trends and determinants of informal and formal caregiving in the community for disabled elderly people in Taiwan

Although family caregiving for elderly people has been the backbone of long-term care in Taiwan, it is not clear whether informal help from family members has diminished in recent years due to changes in social structure and traditions. The objective of this study is to examine the trend and the factors influencing the use of informal and formal caregiving among disabled elders in the community of Taiwan. Data were drawn from three waves of the Taiwan Longitudinal Study on Aging (TLSA) (1999, 2003, and 2007) to examine the receipt of help with activities of daily living (ADLs) in a nationally representative sample of Taiwanese elderly people aged 65 and older. Results showed the trend in having at least 1 of 6 ADL limitations in the community increased mildly in the past decade but a significant rise in the use of paid help compared to informal help between 1999 and 2007. Factors associated with higher likelihood of paid help use included better socio-economic status and more ADLs. However, those living with spouse only were much less likely to use paid help than those living with adult children. Findings suggest that future long-term care (LTC) policy in Taiwan should focus more on providing elders who live alone or with spouse only additional caregiving resource. Given the rapid growth of foreign care workers as primary source of caregiving, the government needs further monitoring to promote care quality and also strategies to develop needs-led home and community based care.

The Changing Relationship Between Obesity and Disability in Middle and Older Adults: 1997 and 2006 China Health and Nutrition Surveys

The Changing Relationship Between Obesity and Disability in Middle and Older Adults: 1997 and 2006 China Health and Nutrition Surveys

Activities of Daily Living, Chronic Medical Conditions, and Health-Related Quality of Life in Older Adults

This study investigated associations between chronic medical conditions, activities of daily living (ADL), and health-related quality of life (HRQOL). Our findings suggest that the number of ADL limitations reported by older adults is associated with their HRQOL. Findings from our analyses also suggest that the association between having multiple comorbid conditions and HRQOL is stronger for those with no ADL limitations than those with at least some limitations. These data will aid practitioners in determining the relative importance of chronic medical conditions and ADL limitations on HRQOL and demonstrate how ADL limitations and comorbid conditions may differentially impact HRQOL.

Older Asian Americans and Pacific Islanders with Activities of Daily Living (ADL) Limitations: Immigration and Other Factors Associated with Institutionalization

This study determined the national prevalence and profile of Asian Americans with Activities of Daily Living (ADL) limitations and identified factors associated with institutionalization. Data were obtained from 2006 American Community Survey, which replaced the long-form of the US Census. The data are nationally representative of both institutionalized and community-dwelling older adults. Respondents were Vietnamese (n = 203), Korean (n = 131), Japanese (n = 193), Filipino (n = 309), Asian Indian (n = 169), Chinese (n = 404), Hawaiian/Pacific Islander (n = 54), and non-Hispanic whites (n = 55,040) aged 55 and over who all had ADL limitations. The prevalence of institutionalized among those with ADL limitations varies substantially from 4.7% of Asian Indians to 18.8% of Korean Americans with ADL limitations. Every AAPI group had a lower prevalence of institutionalization than disabled Non-Hispanic whites older adults (23.8%) (p < 0.001). After adjustment for socio-demographic characteristics, Asian Indians, Vietnamese, Japanese, Filipino, and Chinese had significantly lower odds of institutionalization than non-Hispanic whites (OR = 0.29, 0.31, 0.58, 0.51, 0.70, respectively). When the sample was restricted to AAPIs, the odds of institutionalization were higher among those who were older, unmarried, cognitively impaired and those who spoke English at home. This variation suggests that aggregating data across the AAPI groups obscures meaningful differences among these subpopulations and substantial inter-group differences may have important implications in the long-term care setting.

Do Elderly People at More Severe Activity of Daily Living Limitation Stages Fall More?

The aim of this study was to explore how activity of daily living (ADL) stages and the perception of unmet needs for home accessibility features associate with a history of falling. Participants were from a nationally representative sample from the Second Longitudinal Survey of Aging conducted in 1994. The sample included 9250 community-dwelling persons 70 yrs or older. The associations of ADL stage and perception of unmet needs for home accessibility features with a history of falling within the past year (none, once, or multiple times) were explored after accounting for sociodemographic characteristics and comorbidities using a multinomial logistic regression model. The adjusted relative risk of falling more than once peaked at 4.30 (95% confidence interval, 3.29-5.61) for persons with severe limitation (ADL-III) compared those with no limitation (ADL-0) then declined for those at complete limitation (ADL-IV). The adjusted relative risks of falling once and multiple times were 1.42 (95% confidence interval, 1.07-1.87) and 1.85 (95% confidence interval, 1.44-2.36), respectively, for those lacking home accessibility features. Risk of falling appeared greatest for those whose homes lacked accessibility features and peaked at intermediate ADL limitation stages, presumably at a point when people have significant disabilities but sufficient function to remain partially active.

The relationship between body mass index prior to old age and disability in old age

To analyse the relationship between body mass index (BMI) in middle-age and disability status in old-age using data from the Melbourne Collaborative Cohort Study (MCCS). A total of 41 514 participants enroled in the MCCS between 1990-1994. Height and weight were measured at baseline and disability, defined as limitations to self-care activities of daily living (ADLs) and self-care plus mobility activities, was identified at follow-up (2003-2007). In all, 6300 participants were <65 years at baseline, 70 years at follow-up and not missing BMI at baseline or ADLs at follow-up. The association between BMI in six categories (BMI 18.5-22.5; 22.5-25; 25-27.5; 27.5-30; 30-35; 35+) and disability status was analysed using logistic regression. Models were stratified by sex, and sequentially adjusted for age, education, country of birth, then smoking, alcohol, fruit and vegetable intake, and physical activity. Adjusted odds ratios for composite self-care ADL and mobility limitations compared with BMI 18.5-22.5 kg m(-2) were 1.73 (95%CI 1.14-2.64) for BMI 30-35 kg m(-2) and 3.46 (1.78-6.73) for BMI 35+ kg m(-2) in males. In females, adjusted odds ratios were 1.29 (1.00-1.68) for BMI 22.5-25 kg m(-2), 1.74 (1.35-2.24) for BMI 25-27.5 kg m(-2), 2.58 (1.98-3.36) for BMI 27.5-30 kg m(-2), 2.74 (2.10-3.58) for BMI 30-35 kg m(-2) and 4.21 (3.12-5.88) for BMI 35+ kg m(-2). A graded relationship was observed between BMI and disability in males and females, across the continuum of BMI. These results highlight the importance of a healthy body weight at middle age in order to reduce the risk of disability in old age.

Correlates of the incidence of disability and mortality among older adult Brazilians with and without diabetes mellitus and stroke

BackgroundThe combined effect of diabetes and stroke on disability and mortality remains largely unexplored in Brazil and Latin America. Previous studies have been based primarily on data from developed countries. This study addresses the empirical gap by evaluating the combined impact of diabetes and stroke on disability and mortality in Brazil.MethodsThe sample was drawn from two waves of the Survey on Health and Well-being of the Elderly, which followed 2,143 older adults in São Paulo, Brazil, from 2000 to 2006. Disability was assessed via measures of activities of daily living (ADL) limitations, severe ADL limitations, and receiving assistance to perform these activities. Logistic and multinomial regression models controlling for sociodemographic and health conditions were used to address the influence of diabetes and stroke on disability and mortality.ResultsBy itself, the presence of diabetes did not increase the risk of disability or the need for assistance; however, diabetes was related to increased risks when assessed in combination with stroke. After controlling for demographic, social and health conditions, individuals who had experienced stroke but not diabetes were 3.4 times more likely to have ADL limitations than those with neither condition (95% CI 2.26-5.04). This elevated risk more than doubled for those suffering from a combination of diabetes and stroke (OR 7.34, 95% CI 3.73-14.46). Similar effects from the combination of diabetes and stroke were observed for severe ADL limitations (OR 19.75, 95% CI 9.81- 39.76) and receiving ADL assistance (OR 16.57, 95% CI 8.39-32.73). Over time, older adults who had experienced a stroke were at higher risk of remaining disabled (RRR 4.28, 95% CI 1.53,11.95) and of mortality (RRR 3.42, 95% CI 1.65,7.09). However, risks were even higher for those who had experienced both diabetes and stroke. Diabetes was associated with higher mortality.ConclusionsFindings indicate that a combined history of stroke and diabetes has a great impact on disability prevalence and mortality among older adults in São Paulo, Brazil.

Insufficient Help for Activity of Daily Living Disabilities and Risk of All‐Cause Hospitalization

To determine whether insufficient help for activity of daily living (ADL) disability, a potentially modifiable condition, significantly increases disabled older adults' risk of future hospital admissions. Prospective study. Community-living participants with ADL disabilities in the 1994, 1999, and 2004 National Long-Term Care Survey (NLTCS). Medicare recipients with one or more ADL disabilities completed 5,884 surveys. Times to hospital admission in the year after the NLTCS community survey were obtained from linked Medicare claims. Insufficient ADL help for each ADL limitation was determined from a series of questions common to the three NLTCS community surveys. Insufficient help for one or more ADL limitations was reported in 22% of surveys. Respondents to 3,629 surveys did not experience a hospital admission in the year after the survey. Of the remaining 2,255 surveys, one admission occurred for 382 surveys, two admissions for 525 surveys, three admissions for 193 surveys, and four or more admissions for 155 surveys. Participants reporting insufficient help were 14% (hazard ratio = 1.14, 95% confidence interval = 1.01-1.28) more likely to experience one or more hospitalizations than those who did not report insufficient help after controlling for demographic characteristics, comorbidities, prior hospitalizations, and level of ADL disability. Self-reports of insufficient help provide prognostic information beyond what typical health assessments can capture. Greater recognition and referral for insufficient help for ADL disability may result in lower rates of hospitalization in a population that is at high risk of hospitalization.
