Measuring change in activities of daily living in nursing home residents with moderate to severe cognitive impairment.

BACKGROUND: The objective of this study was to assess the responsiveness of the Minimum Data Set Activities of Daily Living (MDS-ADL) Scale to change over time by examining the change in physical function in adults with moderate to severe dementia with no comorbid illness who had been resident in a nursing home for over 90 days. METHODS: Longitudinal data were collected on nursing home residents with moderate (n = 7001) or severe (n = 4616) dementia in one US state from the US national Minimum Data Set (MDS). Severity of dementia was determined by the MDS Cognitive Performance Scale (CPS). Physical function was assessed by summing the seven items (bed mobility, transfer, locomotion, dressing, eating, toilet use, personal hygiene) on the MDS activities of daily living (ADL) Long Form scale. Mean change over time of MDS-ADL scores were estimated at three and six months for residents with moderate (CPS score of 3) and severe (CPS score of 4 or 5) dementia. RESULTS: Physical function in residents with moderate cognitive impairment deteriorated over six months by an average of 1.78 points on the MDS-ADL Long Form scale, while those with severe cognitive impairment declined by an average of 1.70 points. Approximately one quarter of residents in both groups showed some improvement in physical function over the six month period. Residents with moderate cognitive impairment experienced the greatest deterioration in early-loss and mid-loss ADL items (personal hygiene, dressing, toilet use) and residents with severe cognitive impairment showed the greatest deterioration in activities related to eating, a late loss ADL. CONCLUSION: The MDS-ADL Long Form scale detected clinically meaningful change in physical function in a large cohort of long-stay nursing home residents with moderate to severe dementia, supporting its use as a research tool in future studies.

Contribution of infection to increased mortality in women after cardiac surgery.

BACKGROUND: Women have higher mortality rates after coronary artery bypass graft (CABG) surgery compared with men. Explanations for this sex difference are controversial. The objective of this study was to assess whether infection contributes to the increased risk of mortality in women. METHODS: We conducted a cohort study of 9218 Michigan Medicare beneficiaries hospitalized for CABG surgery. The prevalence of infection at any site during hospitalization was determined. Patients were followed up for 100 days after surgery to assess vital status. Analyses were conducted using proportional hazards regression and population attributable risk. RESULTS: Women hospitalized for CABG surgery were more likely to have an infection than men (16.1% vs 9.8%, P<.001), regardless of age, race, type of admission, hospital volume, or presence of comorbidities. Infections of the respiratory tract, urinary tract, digestive tract, and skin and subcutaneous tissue were more common in women than in men. The risk of death in men increased 3-fold with infection, whereas the risk in women increased 1.8-fold. The interaction between infection and sex on mortality was significant after adjusting for age, type of admission, and presence of comorbidities (P = .008). The unadjusted percentage of deaths attributable to female sex was 13.9%, which decreased to 0.3% when adjusted for infection. Of the excess deaths in women, 96% could be accounted for by the differential distribution of infection between the sexes. CONCLUSION: The increased risk of mortality after CABG surgery in women may be explained by underlying differences in the prevalence of infection among men and women.

Risk adjustment methods for Home Care Quality Indicators (HCQIs) based on the minimum data set for home care.

BACKGROUND: There has been increasing interest in enhancing accountability in health care. As such, several methods have been developed to compare the quality of home care services. These comparisons can be problematic if client populations vary across providers and no adjustment is made to account for these differences. The current paper explores the effects of risk adjustment for a set of home care quality indicators (HCQIs) based on the Minimum Data Set for Home Care (MDS-HC). METHODS: A total of 22 home care providers in Ontario and the Winnipeg Regional Health Authority (WRHA) in Manitoba, Canada, gathered data on their clients using the MDS-HC. These assessment data were used to generate HCQIs for each agency and for the two regions. Three types of risk adjustment methods were contrasted: a) client covariates only; b) client covariates plus an "Agency Intake Profile" (AIP) to adjust for ascertainment and selection bias by the agency; and c) client covariates plus the intake Case Mix Index (CMI). RESULTS: The mean age and gender distribution in the two populations was very similar. Across the 19 risk-adjusted HCQIs, Ontario CCACs had a significantly higher AIP adjustment value for eight HCQIs, indicating a greater propensity to trigger on these quality issues on admission. On average, Ontario had unadjusted rates that were 0.3% higher than the WRHA. Following risk adjustment with the AIP covariate, Ontario rates were, on average, 1.5% lower than the WRHA. In the WRHA, individual agencies were likely to experience a decline in their standing, whereby they were more likely to be ranked among the worst performers following risk adjustment. The opposite was true for sites in Ontario. CONCLUSIONS: Risk adjustment is essential when comparing quality of care across providers when home care agencies provide services to populations with different characteristics. While such adjustment had a relatively small effect for the two regions, it did substantially affect the ranking of many individual home care providers.

Measuring depression in nursing home residents with the MDS and GDS: an observational psychometric study.

BACKGROUND: The objective of this study was to examine the Minimum Data Set (MDS) and Geriatric Depression Scale (GDS) as measures of depression among nursing home residents. METHODS: The data for this study were baseline, pre-intervention assessment data from a research study involving nine nursing homes and 704 residents in Massachusetts. Trained research nurses assessed residents using the MDS and the GDS 15-item version. Demographic, psychiatric, and cognitive data were obtained using the MDS. Level of depression was operationalized as: (1) a sum of the MDS Depression items; (2) the MDS Depression Rating Scale; (3) the 15-item GDS; and (4) the five-item GDS. We compared missing data, floor effects, means, internal consistency reliability, scale score correlation, and ability to identify residents with conspicuous depression (chart diagnosis or use of antidepressant) across cognitive impairment strata. RESULTS: The GDS and MDS Depression scales were uncorrelated. Nevertheless, both MDS and GDS measures demonstrated adequate internal consistency reliability. The MDS suggested greater depression among those with cognitive impairment, whereas the GDS suggested a more severe depression among those with better cognitive functioning. The GDS was limited by missing data; the DRS by a larger floor effect. The DRS was more strongly correlated with conspicuous depression, but only among those with cognitive impairment. CONCLUSIONS: The MDS Depression items and GDS identify different elements of depression. This may be due to differences in the manifest symptom content and/or the self-report nature of the GDS versus the observer-rated MDS. Our findings suggest that the GDS and the MDS are not interchangeable measures of depression.

Skilled nursing facility rehabilitation and discharge to home after stroke.

OBJECTIVE: To determine the relation between rehabilitation therapy (RT) intensity and time to discharge home for stroke patients in skilled nursing facilities (SNFs). DESIGN: Retrospective cohort study. We used regression analyses, stratified by expected outcome, and propensity score adjustment. Setting All SNFs in Ohio, Michigan, and Ontario, Canada. PARTICIPANTS: A cohort of residents, aged 65 and over, admitted from hospitals to SNFs with a diagnosis of stroke (N=23,824). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Time to discharge home from an SNF. RESULTS: RT was given to more than 95% of residents for whom discharge was expected within 90 days and to more than 60% of residents for whom discharge was uncertain or not expected. RT increased the likelihood of discharge to the community for all groups except those expected to be discharged within 30 days. The dose-response relation was strongest for residents with either an uncertain discharge prognosis or no discharge expected. CONCLUSIONS: Postacute residents with an uncertain prognosis are an important target population for intensive RT.

A national study showed that diagnoses varied by age group in nursing home residents under age 65.

OBJECTIVE: Those aged <65 in nursing homes (NHs) are substantially different from elderly residents. This study uses data gathered from the Resident Assessment Instrument's Minimum Data Set (MDS) to describe these relatively rare residents. STUDY DESIGN AND SETTING: The study uses MDS assessments of close to three-quarter million residents in nine states from 1994 to 1996. Residents are described within chronological age group (0-4, 5-14, etc.). Factor analysis is used to develop diagnostic clusters, and the prevalence of these clusters, functional problems, other conditions, and treatments is described for each group. RESULTS: Thirteen diagnostic clusters describe nearly 85% of all NH residents and highlight differences between age groups. Pediatric residents are substantially more physically and cognitively impaired than young adult residents, and have the highest case mix burden of care. The youngest population primarily has diagnoses related to mental retardation and developmental disabilities, young adults have the highest prevalence of hemi- and quadriplegia, while older residents are typified by increasing prevalence of neurological diagnoses. CONCLUSION: This study offers an initial description of NH residents <65. The prevalence of residents with unique conditions may suggest the need to modify the MDS assessment instrument.

Elder disability as an explanation for racial differences in informal home care.

PURPOSE: Adjusting for sociodemographic characteristics and disability levels, this study examines whether differences exist in the structure and function of community-dwelling Black and White frail elders' informal care networks. DESIGN AND METHODS: Data from in-person assessments of Michigan's Home and Community-Based Medicaid Waiver applicants were analyzed by using logistic and ordinary least squares regression. The sample consisted of 936 Black and 3,182 White frail elderly persons. RESULTS: When sociodemographic characteristics were controlled for, racial differences were found in all informal care components except out-of-home chores. Differences in functional components (amount of care, scope of assistance, and personal care) were largely accounted for by disability, whereas racial differences in the structural components (source of care, living arrangement, and sole caregiver) and in-home chores were not. IMPLICATIONS: Findings suggest that Blacks are not better off than Whites in the receipt of informal care. Although Black elders receive more informal help, this difference is primarily because Blacks are more disabled. This study calls for heightened awareness of disability among low-income Blacks and the potential burden experienced by their caregivers.

Insomnia and hypnotic use, recorded in the minimum data set, as predictors of falls and hip fractures in Michigan nursing homes.

OBJECTIVES: To examine the relationship between insomnia, hypnotic use, falls, and hip fractures in older people. DESIGN: Secondary analysis of a large, longitudinal, assessment database. SETTING: Four hundred thirty-seven nursing homes in Michigan. PARTICIPANTS: Residents aged 65 and older in 2001 with a baseline Minimum Data Set assessment and a follow-up 150 to 210 days later. MEASUREMENTS: Logistic regression modeled any follow-up report of fall or hip fracture. Predictors were baseline reports of insomnia (previous month) and use of hypnotics (previous week). Potential confounds taken into account included standard measures of functional status, cognitive status, intensity of resource utilization, proximity to death, illness burden, number of medications, emergency room visits, nursing home new admission, age, and sex. RESULTS: In 34,163 nursing home residents (76% women, mean age+/-standard deviation 84+/-8), hypnotic use did not predict falls (adjusted odds ratio (AOR)=1.13, 95% confidence interval (CI)=0.98, 1.30). In contrast, insomnia did predict future falls (AOR=1.52, 95% CI=1.38, 1.66). Untreated insomnia (AOR=1.55, 95% CI=1.41, 1.71) and hypnotic-treated (unresponsive) insomnia (AOR=1.32, 95% CI=1.02, 1.70) predicted more falls than did the absence of insomnia. After adjustment for confounding variables, insomnia and hypnotic use were not associated with subsequent hip fracture. CONCLUSION: In elderly nursing home residents, insomnia, but not hypnotic use, is associated with a greater risk of subsequent falls. Future studies will need to confirm these findings and determine whether appropriate hypnotic use can protect against future falls.

Skilled care requirements for elderly patients after coronary artery bypass grafting.

OBJECTIVES: To examine the extent to which elderly individuals use various skilled care facilities after coronary artery bypass grafting (CABG). DESIGN: Retrospective cohort study. SETTING: State of Michigan from 1997 to 1998. PARTICIPANTS: Residents aged 65 and older enrolled in Medicare who underwent CABG. MEASUREMENTS: Cumulative incidence of admission within 100 days of hospital discharge, relative risk (RR) of admission, readmission or extended stay at a skilled care facility, and length of stay in a skilled care facility. RESULTS: Fifty percent of patients aged 80 and older used a skilled care facility after CABG, with most requiring admission to a skilled nursing facility (SNF) or readmission to an acute-care hospital within 100 days after discharge. Patients aged 80 and older had a significantly higher risk of admission to a SNF (adjusted RR=3.3, 95% confidence interval (CI)=2.8-4.0) than did those aged 65 to 69, as did patients aged 75 to 79 (adjusted RR=2.2, 95% CI=1.8-2.6) and those aged 70 to 74 (adjusted RR=1.5, 95% CI=1.3-1.8). The length of time spent in skilled care facilities significantly increased with age (mean days=13.3 for aged 65-69, 16.9 for 70-74, 19.6 for 75-79, and 22.9 for 80 and older; P<.001). CONCLUSION: Older patients are more likely to be admitted to a SNF, be readmitted to an acute-care hospital, and have longer institutional stays after CABG. When balancing the risks and benefits of CABG, physicians, patients, families, and policy-makers need to carefully consider the likelihood of follow-up institutional care in elderly patients.

Estimating prognosis for nursing home residents with advanced dementia.

CONTEXT: Survival varies for patients with advanced dementia, and accurate prognostic tools have not been developed. A small proportion of patients admitted to hospice have dementia, in part because of the difficulty in predicting survival. OBJECTIVES: To identify factors associated with 6-month mortality in newly admitted nursing home residents with advanced dementia and to create a practical risk score to predict 6-month mortality in this population. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective cohort study of data from the Minimum Data Set (MDS). All Medicare or Medicaid licensed nursing homes in New York and Michigan were included. Participants had advanced dementia and were admitted to New York nursing homes between June 1, 1994, and December 30, 1998 (derivation cohort, n = 6799), and to Michigan nursing homes from October 1, 1998, through July 30, 2000 (validation cohort, n = 4631). MAIN OUTCOME MEASURES: MDS factors associated with 6-month mortality were determined in the derivation group, and the resulting mortality risk score was evaluated in the validation cohort. Risk score performance was compared with the cut point of 7c on the Functional Assessment Staging (FAST) scale. RESULTS: Among residents with advanced dementia, 28.3% (n = 1922) died within 6 months of nursing home admission in the derivation cohort; 35.1% (n = 1626) died in the validation cohort. The 6-month mortality rate increased across risk scores (possible range, 0-19): 0 points, 8.9% mortality; 1 to 2, 10.8%; 3 to 5, 23.2%; 6 to 8, 40.4%; 9 to 11, 57.0%; and at least 12, 70.0% in the validation cohort. The area under the receiver operating characteristic (AUROC) curve for predicting 6-month mortality was 0.74 and 0.70 in the derivation and validation cohorts, respectively. Our risk score demonstrated better discrimination to predict 6-month mortality (AUROC, 0.64 for a cutoff of > or =6 points vs 0.51 for FAST stage 7c). CONCLUSION: A risk score based on 12 variables from the MDS estimates 6-month mortality for nursing home residents with advanced dementia with greater accuracy than existing prognostic guidelines.

Payer incentives and physical rehabilitation therapy for nonelderly institutional long-term care residents: evidence from Michigan and Ontario.

OBJECTIVE: To examine the effect of payment incentives on the provision of rehabilitation therapy to non elderly nursing home residents. DESIGN: Retrospective cross-sectional study. SETTING: Nursing homes in Michigan or complex continuing care facilities in Ontario, Canada, in 1998 or 1999. PARTICIPANTS: Non elderly nursing home residents (N=5189) admitted to nursing homes. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The effect of payment on access to physical therapy (PT) and occupational therapy (OT) and total weekly time for each therapy type. RESULTS: A Medicare policy change from cost-based to a patient-specific case-mix payment method was associated with greater likelihood of receiving OT but reduced weekly minutes of PT and OT provided to residents. Medicare cost-based and private insurance were associated with greater likelihood of receiving OT and PT and more therapy time for both types of therapy compared with private-pay residents. Global budget payment was associated with greater access to PT but fewer weekly minutes of OT and PT. CONCLUSIONS: Little information exists to describe the characteristics and treatment of non elderly nursing home residents. This study found that many of these residents received rehabilitation and that residents whose care was paid for by more generous payers, such as Medicare, received more therapy than those paid for by less generous payers.

Case-mix adjustment and efficiency measurement.

AIMS: The importance of using valid case-mix systems in long-term care is addressed by comparing the predictive power of different case-mix models, and by applying them in the calculation of technical efficiency scores of care units. METHODS: To construct different case-mix models a statistical clustering technique (Automatic Interaction Detection) was used. Technical efficiency score were calculated using data envelopment analysis (DEA). RESULTS: The Resource Utilization Groups (RUG-III/22) classification explained 39% of resident specific cost, compared with 16% for a functional dependency scale in the Finnish patient information system HILMO. CONCLUSION: When assessing the economic performance of long-term care units it is important to pay attention to the predictive validity of the case-mix measure to be used. The choice of case-mix measure significantly affected how units were rated in efficiency.

Terminal care for persons with advanced dementia in the nursing home and home care settings.

BACKGROUND: Many older persons with advanced dementia receive terminal care in nursing homes, others remain in the community with home care services. OBJECTIVES: To describe and compare the end-of-life experience of persons dying with advanced dementia in the nursing home and home care settings. DESIGN: Retrospective cohort study. SETTING/SUBJECTS: Persons 65 years or older with advanced dementia who died within 1 year of admission to either a nursing home in Michigan between July 1, 1998 until December 31, 2000 (n = 2730), or the state's publicly funded home and community-based services from October 1, 1998 until December 31, 2001 (n = 290). MEASUREMENTS: Data were derived from the Minimum Data Set (MDS)-Nursing home Version 2.0 for the institutionalized sample, and the MDS-Home Care for the community-based sample. Variables from the MDS assessment completed within 180 days of death were used to describe the end-of-life experiences of these two groups. RESULTS: Nursing home residents dying with advanced dementia were older, had greater functional impairment, and more behavior problems compared to home care clients. Few subjects in the nursing home (10.3%) and home care (15.6%) cohorts were perceived to have less than 6 months to live. Only 5.7% of nursing home residents and 10.7% home care clients were referred to hospice. Hospitalizations were frequent: nursing home, 43.7%; home care, 31.5%. Pain and shortness of breath were common in both settings. End-of-life variables independently associated with nursing home versus home care included: hospice (adjusted odds ratio [AOR] 0.26, 95% confidence interval [CI], 0.16-0.43), life expectancy less than 6 months (AOR 0.31; 95% CI, 0.20-0.48), advance directives (AOR, 1.48; 95% CI, 1.11-1.96), pain (AOR, 0.38; 95% CI, 0.29-0.50), shortness of breath (AOR 0.20; 95% CI (0.13-0.28), and oxygen therapy (AOR, 2.47; 95% CI, 1.51-4.05). CONCLUSIONS: Persons dying with advanced dementia admitted to nursing homes have different characteristics compared to those admitted to home care services. Their end-of-life experiences also differ in these two sites of care. However, palliative care was not optimal in either setting.

Home care quality indicators (HCQIs) based on the MDS-HC.

PURPOSE: This study aimed to develop home care quality indicators (HCQIs) to be used by a variety of audiences including consumers, agencies, regulators, and policy makers to support evidence-based decision making related to the quality of home care services. DESIGN AND METHODS: Data from 3,041 Canadian and 11,252 U.S. home care clients assessed with the Minimum Data Set-Home Care (MDS-HC) were used to evaluate a series of indicators suggested by international experts and by focus groups conducted in Canada and the United States. Risk adjustment methods were derived and validated using data from Ontario and Michigan. RESULTS: Of the 73 original candidate HCQIs, 22 were retained for the final list of recommended indicators. All but three indicators include risk adjusters based on individual-level covariates. An agency-level risk adjustment was developed to correct for selection and ascertainment bias. IMPLICATIONS: The HCQIs are new tools providing a first step along the path of quality improvement for home care. These indicators can provide high-quality evidence on performance at the agency level and on a regional basis.

Is telephone screening feasible? Accuracy and cost-effectiveness of identifying people medically eligible for home- and community-based services.

PURPOSE: To determine the accuracy of a telephone-screening system to identify persons eligible for home- and community-based long-term care. DESIGN AND METHODS: Data from Michigan telephone screens were compared to data from in-person assessments using the Minimum Data Set for Home Care (MDS-HC). Weighted kappa statistics measured the level of agreement between the two assessments. RESULTS: Overall, recommendations based on the telephone screen produced a marginal match compared to recommendations based on in-person assessment. "False positives" (individuals scoring as more impaired on the telephone screen than in person) occurred in 27% of all cases, while "false negatives" (individuals scoring as less impaired on the telephone screen) only occurred among 6% of the callers. Neither individual screen questions, source of information, location of the individual, timing between screen and assessment, nor temporal changes accounted for mismatches. Telephone screens resulted in an 11% savings over the cost of providing in-person assessments to all program seekers. IMPLICATIONS: The telephone screen has utility as a broad targeting mechanism that allows agencies to avoid costly in-person assessments for all program seekers. Evidence does not support use of the telephone screen alone to determine either medical eligibility or a specific level of care.

Identifying older people at risk of abuse during routine screening practices.

OBJECTIVES: To examine the association between various characteristics of community-based older people and a constructed measure of potential elder abuse. DESIGN: Cross-sectional design. SETTING: Public community-based long-term care programs in Michigan. PARTICIPANTS: Individuals aged 60 and older seeking home and community-based services in Michigan between November 1996 and October 1997 (N = 701). MEASUREMENTS: Data were collected using the Minimum Data Set for Home Care (MDS-HC) assessment. The dependent variable is a constructed measure of potential elder abuse reflecting physical and emotional abuse and neglect. Independent variables include demographic characteristics; diagnoses; behavioral measures; and cognitive, physical, and social functioning. RESULTS: Several measures of social support and social function were strongly associated with the signs of a potentially abusive environment: brittle support (odds ratio (OR) = 3.5, 90% confidence interval (CI) = 1.5-8.1), older person feels lonely (OR = 2.4, 90% CI = 1.3-4.5), and older person expresses conflict with family/friends (OR = 2.3, 90% CI = 1.2-4.3). Home care participants' alcohol abuse, psychiatric illness, lack of ease interacting with others, and short-term memory problems were also significantly associated with the signs of potential elder abuse. CONCLUSIONS: The results of this study suggest that the signs of potential elder abuse are associated with a diminishing social network and poor social functioning, although some characteristics of the older person's health are contributing factors. Improved understanding of the link between those characteristics and potential abuse will help healthcare providers, case managers, and others identify older people at high risk of abuse.

Six-month cognitive improvement in nursing home residents with severe cognitive impairment.

The number of patients in nursing homes with severe cognitive impairment (SCI) is growing. The authors compared the characteristics and 6-month outcomes of a sample of nursing home residents with SCI to those of other residents. This cross-sectional and 6-month follow-up study used data from pooled 1990 and 1993 cohorts in the Resident Assessment Instrument Evaluation Study. The authors compared baseline characteristics of residents with SCI (n = 1304) with all others and evaluated 6-month improvement and associated factors in the SCI group. SCI residents had poorer nutrition and lower frequencies of most symptoms and chronic diseases. Fourteen percent showed 6-month cognitive improvement, associated with higher baseline function, antidepressant medication, and recent falls. Nursing home residents with SCI had possible underrecognition of medical problems and poor nutritional status. Measured improvement may indicate possible misclassification for some residents and potential for improvement for others.

Does quality influence consumer choice of nursing homes? Evidence from nursing home to nursing home transfers.

We estimated Cox proportional hazards models using assessment data from the Minimum Data Set to test whether nursing home residents and their proxies respond to quality of care by changing providers. Various indicators of poor quality increased the likelihood of transfer. Residents of for-profit homes or homes with excess capacity also were more likely to transfer. Inability to participate in care decisions and factors indicating frailty limited residents' ability to transfer. The apparent responsiveness to quality is encouraging. Nonetheless, because the absolute transfer rate is low, significant barriers to movement among nursing homes still may exist.
