Refining a case-mix measure for nursing homes: Resource Utilization Groups (RUG-III)

Supporting generalist nurses in the rural setting with the introduction of a clinical assessment process

The aim of this research was to evaluate the implementation of an assessment process for general nurses involved in providing end-of-life care. A mixed-method, three-phased study was conducted on a medical ward at a regional hospital in a rural setting. Participating nurses completed a questionnaire about their awareness levels of the five validated scales included in the assessment of patients receiving palliative care. Auditing of the completed assessment forms was conducted at the interim and post data collection points and focus groups were conducted in the final phase. Analysis of the data revealed that nurses were able to integrate the use of this assessment process into the care of this group of patients. The author concludes, while nurses working in rural settings require general clinical knowledge of a wide range of patient groups, validated assessment scales can assist them in the provision of evidence-based palliative care.

The Pediatric Home Care/Expenditure Classification Model (P/ECM): A Home Care Case-Mix Model for Children Facing Special Health Care Challenges

Case-mix classification and payment systems help assure that persons with similar needs receive similar amounts of care resources, which is a major equity concern for consumers, providers, and programs. Although health service programs for adults regularly use case-mix payment systems, programs providing health services to children and youth rarely use such models. This research utilized Medicaid home care expenditures and assessment data on 2,578 children receiving home care in one large state in the USA. Using classification and regression tree analyses, a case-mix model for long-term pediatric home care was developed. The Pediatric Home Care/Expenditure Classification Model (P/ECM) grouped children and youth in the study sample into 24 groups, explaining 41% of the variance in annual home care expenditures. The P/ECM creates the possibility of a more equitable, and potentially more effective, allocation of home care resources among children and youth facing serious health care challenges.

Does More Therapy in Skilled Nursing Facilities Lead to Better Outcomes in Patients With Hip Fracture?

BACKGROUND

Skilled nursing facilities (SNFs) have increasingly been providing more therapy hours to beneficiaries of Medicare. It is not known whether these increases have improved patient outcomes.

OBJECTIVE

The study objectives were: (1) to examine temporal trends in therapy hour volumes and (2) to evaluate whether more therapy hours are associated with improved patient outcomes.

DESIGN

This was a retrospective cohort study.

METHODS

Data sources included the Minimum Data Set, Medicare inpatient claims, and the Online Survey, Certification, and Reporting System. The study population consisted of 481,908 beneficiaries of Medicare fee-for-service who were admitted to 15,496 SNFs after hip fracture from 2000 to 2009. Linear regression models with facility and time fixed effects were used to estimate the association between the quantity of therapy provided in SNFs and the likelihood of discharge to home.

RESULTS

The average number of therapy hours increased by 52% during the study period, with relatively little change in case mix at SNF admission. An additional hour of therapy per week was associated with a 3.1-percentage-point (95% confidence interval=3.0, 3.1) increase in the likelihood of discharge to home. The effect of additional therapy decreased as the Resource Utilization Group category increased, and additional therapy did not benefit patients in the highest Resource Utilization Group category.

LIMITATIONS

Minimum Data Set assessments did not cover details of therapeutic interventions throughout the entire SNF stay and captured only a 7-day retrospective period for measures of the quantity of therapy provided.

CONCLUSIONS

Increases in the quantity of therapy during the study period cannot be explained by changes in case mix at SNF admission. More therapy hours in SNFs appear to improve outcomes, except for patients with the greatest need.

Heterogeneity of Characteristics among Housing Adaptation Clients in Sweden--Relationship to Participation and Self-Rated Health

The aim of the paper was to explore the heterogeneity among housing adaptation clients. Cluster analysis was performed using baseline data from applicants in three Swedish municipalities. The analysis identified six main groups: “adults at risk of disability”, “young old with disabilities”, “well-functioning older adults”, “frail older adults”, “frail older with moderate cognitive impairments” and “resilient oldest old”. The clusters differed significantly in terms of participation frequency and satisfaction in and outside the home as well as in terms of self-rated health. The identification of clusters in a heterogeneous sample served the purpose of finding groups with different characteristics, including participation and self-rated health which could be used to facilitate targeted home-based interventions. The findings indicate that housing adaptions should take person/environment/activity specific characteristics into consideration so that they may fully serve the purpose of facilitating independent living, as well as enhancing participation and health.

Trajectories of Disability Among Older Persons Before and After a Hospitalization Leading to a Skilled Nursing Facility Admission

OBJECTIVES

To identify distinct sets of disability trajectories in the year before and after a Medicare qualifying skilled nursing facility (Q-SNF) admission, evaluate the associations between the pre-and post-Q-SNF disability trajectories, and determine short-term outcomes (readmission, mortality).

DESIGN, SETTING, AND PARTICIPANTS

Prospective cohort study including 754 community-dwelling older persons, 70+ years, and initially nondisabled in their basic activities of daily living. The analytic sample included 394 persons, with a first hospitalization followed by a Q-SNF admission between 1998 and 2012.

MAIN OUTCOMES AND MEASURES

Disability in the year before and after a Q-SNF admission using 13 basic, instrumental, and mobility activities. Secondary outcomes included 30-day readmission and 12-month mortality.

RESULTS

The mean (SD) age of the sample was 84.9 (5.5) years. We identified 3 disability trajectories in the year before a Q-SNF admission: minimal disability (37.3% of participants), mild disability (44.6%), and moderate disability (18.2%). In the year after a Q-SNF admission, all participants started with moderate to severe disability scores. Three disability trajectories were identified: substantial improvement (26.0% of participants), minimal improvement (36.5%), and no improvement (37.5%). Among participants with minimal disability pre-Q-SNF, 52% demonstrated substantial improvement; the other 48% demonstrated minimal improvement (32%) or no improvement (16%) and remained moderately to severely disabled in the year post-Q-SNF. Among participants with mild disability pre-Q-SNF, 5% showed substantial improvement, whereas 95% showed little to no improvement. Of participants with moderate disability pre-Q-SNF, 15% remained moderately disabled showing little improvement, whereas 85% showed no improvement. Participants who transitioned from minimal disability pre-Q-SNF to no improvement post-Q-SNF had the highest rates of 30-day readmission and 12-month mortality (rate/100 person-days 1.3 [95% CI 0.6-2.8] and 0.3 [95% CI 0.15-0.45], respectively).

CONCLUSIONS

Among older persons, distinct disability trajectories were observed in the year before and after a Q-SNF admission. The likelihood of improvement in disability was greatly constrained by the pre-Q-SNF disability trajectory. Most older persons remained moderately to severely disabled in the year following a Q-SNF admission.

Comprehensive Care Plan Development Using Resident Assessment Instrument Framework: Past, Present, and Future Practices

Development of the comprehensive care plan (CCP) is a requirement for nursing homes participating in the federal Medicare and Medicaid programs, referred to as skilled nursing facilities. The plan must be developed within the context of the comprehensive interdisciplinary assessment framework-the Resident Assessment Instrument (RAI). Consistent compliance with this requirement has been difficult to achieve. To improve the quality of CCP development within this framework, an increased understanding of complex factors contributing to inconsistent compliance is required. In this commentary, we examine the history of the comprehensive care plan; its development within the RAI framework; linkages between the RAI and registered nurse staffing; empirical evidence of the CCP's efficacy; and the limitations of extant standards of practices in CCP development. Because of the registered nurse's educational preparation, professional practice standards, and licensure obligations, the essential contributions of professional nurses in CCP development are emphasized. Recommendations for evidence-based micro and macro level practice changes with the potential to improve the quality of CCP development and regulatory compliance are presented. Suggestions for future research are given.

Volume Matters: Returning Home After Hip Fracture

OBJECTIVES

To examine the effect of the relationship between volume (number of hip fracture admissions during the 12 months before participant's fracture) and other facility characteristics on outcomes.

DESIGN

Prospective observational study.

SETTING

U.S. skilled nursing facilities (SNFs) admitting individuals discharged from the hospital after treatment for hip fracture between 2000 and 2007 (N = 15,439).

PARTICIPANTS

Community-dwelling fee-for-service Medi-care beneficiaries aged 75 and older admitted to U.S. hospitals for their first hip fracture and discharged to a SNF for postacute care from 2000 to 2007 (N = 512,967).

MEASUREMENTS

Successful discharge from SNF to community, defined as returning to the community within 30 days of hospital discharge to the SNF and remaining in the community without being institutionalized for at least 30 days, was examined using Medicare administrative data, propensity score matching, and instrumental variables.

RESULTS

The overall rate of successful discharge to the community was 31%. Of the 15,439 facilities, the facility interquartile range varied from 0% (25th percentile) to 42% (75th percentile). An important determinant of variation in discharge rate was SNF volume of hip fracture admissions. Unadjusted successful discharge from SNF to community was 43.7% in high-volume facilities (>24 admissions/year), versus 18.8% in low-volume facilities (1-6 admissions/year). This facility volume effect persisted after adjusting for participant and facility characteristics associated with outcomes (e.g., adjusted odds ratio = 2.06, 95% confidence interval = 1.91-2.21 for volume of 25 vs 3 admissions per year).

CONCLUSION

In community-dwelling persons with their first hip fracture, successful return to the community varies substantially according to SNF provider volume and staffing characteristics.

Costs of care for people with dementia just before and after nursing home placement: primary data from eight European countries

BACKGROUND

Dementia is the most common cause of functional decline among elderly people and is associated with high costs of national healthcare in European countries. With increasing functional and cognitive decline, it is likely that many people suffering from dementia will receive institutional care in their lifetime. To delay entry to institutional care, many European countries invest in home and community based care services.

OBJECTIVES

This study aimed to compare costs for people with dementia (PwD) at risk for institutionalization receiving professional home care (HC) with cost for PwD recently admitted to institutional long-term nursing care (ILTC) in eight European countries. Special emphasis was placed on differences in cost patterns across settings and countries, on the main predictors of costs and on a comprehensive assessment of costs from a societal perspective.

METHODS

Interviews using structured questionnaires were conducted with 2,014 people with dementia and their primary informal caregivers living at home or in an ILTC facility. Costs of care were assessed with the resource utilization in dementia instrument. Dementia severity was measured with the standardized mini mental state examination. ADL dependence was assessed using the Katz index, neuropsychiatric symptoms using the neuropsychiatric inventory (NPI) and comorbidities using the Charlson. Descriptive analysis and multivariate regression models were used to estimate mean costs in both settings. A log link generalized linear model assuming gamma distributed costs was applied to identify the most important cost drivers of dementia care.

RESULTS

In all countries costs for PwD in the HC setting were significantly lower in comparison to ILTC costs. On average ILTC costs amounted to 4,491 Euro per month and were 1.8 fold higher than HC costs (2,491 Euro). The relation of costs between settings ranged from 2.4 (Sweden) to 1.4 (UK). Costs in the ILTC setting were dominated by nursing home costs (on average 94%). In the HC setting, informal care giving was the most important cost contributor (on average 52%). In all countries costs in the HC setting increased strongly with disease severity. The most important predictor of cost was ADL independence in all countries, except Spain and France where NPI severity was the most important cost driver. A standard deviation increase in ADL independence translated on average into a cost decrease of about 22%.

CONCLUSION

Transition into ILTC seems to increase total costs of dementia care from a societal perspective. The prevention of long-term care placement might be cost reducing for European health systems. However, this conclusion depends on the country, on the valuation method for informal caregiving and on the degree of impairment.

Who receives rehabilitation in canadian long-term care facilities? A cross-sectional study

PURPOSE

To describe the proportion of residents receiving occupational therapy (OT) and physical therapy (PT) and the factors associated with receiving PT in long-term care (LTC) facilities across five provinces and one territory in Canada.

METHODS

Using a population-based, retrospective analysis of cross-sectional data, the proportion of LTC facility residents in each province or territory receiving three different amounts (time and frequency) of PT, OT, or both before July 1, 2013, was calculated according to the Resource Utilization Groups-III rehabilitation classifications. Twenty-three variables from the Resident Assessment Instrument 2.0, such as age and cognition, were examined as correlates; those significant at p<0.01 were included in a multivariate logistic regression.

RESULTS

Between 63.7% and 88.6% of residents did not receive any PT or OT; 0.8%-12.6% received both PT and OT; 5.8%-29.5% received an unspecified amount of PT; 1.9%-7.0% received 45 minutes or more of PT 3 days or more per week; and fewer than 1% received 150 minutes or more of PT on 5 or more days per week. Province, age, cognitive status, depression, clinical status, fracture, multiple sclerosis, and self-rated potential for improvement were associated with PT irrespective of time intensity.

CONCLUSIONS

The proportion of LTC residents receiving rehabilitation services varies across Canada and appears to be associated with physical impairments and the potential for improvement; older residents with cognitive impairment or mood disorders are less likely to receive rehabilitation services. Future recommendations should consider what is driving the patterns of service use, determine whether the resources available are appropriate, and address the most appropriate goals for residents in LTC.

Incomplete assessments: towards a better understanding of causes and solutions. The case of the interRAI home care instrument in Belgium

The chronic diseases, comorbidities and rapidly changing needs of frail older persons increase the complexity of caregiving. A comprehensive, systematic and structured collection of data on the status of the frail older person is presumed to be essential in facilitating decision-making and thus improving the quality of care provided. However, the way in which an assessment is completed has a substantial impact on the quality and value of the results. This study examines the online completion of interRAI Home Care assessments, the possible causes for incomplete assessments and the consequences of these factors with respect to the quality of care received. Our findings indicate high nurse engagement and poor physician participation. We also observed the poor completion of items in predominantly medically- oriented sections characterized by, first, the fact that the assessors felt incapable of answering certain questions, second, the absence of required data or of a competent person to fill out the data, and third, the lack of tools necessary for essential measurements. The incompleteness of assessments has a clear negative influence on outcome generation. Moreover, without the added value of support outcomes, the improvement of care quality can be impeded and information technology can easily be seen as burdensome by the assessors. We have observed that multidisciplinary cooperation is an important prerequisite to establishing high-quality assessments aimed at improving the quality of care.

Functional disability and nursing resource use are predictive of antimicrobial resistance in nursing homes

OBJECTIVES

To use a simple measure of activities of daily living, wounds, and indwelling devices (urinary catheter, feeding tube) to predict prevalent, new, and intermittent multidrug-resistant organism (MDRO) acquisition in nursing home (NH) residents.

DESIGN

Secondary analysis, prospective cohort study.

SETTING

Southeast Michigan NHs (n = 15).

PARTICIPANTS

NH residents (N = 111, mean age 81) with two or more monthly visits (729 total).

MEASUREMENTS

Monthly microbiological surveillance for MDROs from multiple anatomic sites from enrollment until discharge or 1 year. The Arling scale, previously developed as a measure of NH residents' need (time-intensity) for nursing resources, was used to predict prevalent and time to new or intermittent acquisition (months) of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and antibiotic-resistant gram-negative bacteria (R-GNB) colonization using multiple-failure accelerated time-factor survival analysis, controlling for comorbidity, hospitalization, and antibiotic use in the prior month.

RESULTS

One-fifth of participants had a wound, and one-third had a device. There were 60 acquisitions of MRSA, 56 of R-GNB, and 15 of VRE. Expected time to acquisition was less than 1 year for MRSA (median 6.7 months) and R-GNB (median 4.5 months) and more than 1 year for VRE (median 40 months). Arling score was associated with earlier new MRSA and VRE acquisition. A resident with only mild functional impairment and no device or wound would be expected to acquire MRSA in 20 months, versus 5 months for someone needing the most-intense nursing contact.

CONCLUSION

MDRO acquisition is common in community NHs. Need for nursing care predicts new MDRO acquisition in NHs, suggesting potential mechanisms for MDRO acquisition and strategies for future interventions for high-risk individuals (e.g., enhanced barrier precautions).

[Resident assessment instrument. Application options and relevance for Germany]

The Resident Assessment Instrument (RAI) is a structured and standardized instrument to improve the quality of long-term care. It is based on the Minimum Data Set (MDS) 3.0 to generate clinical data for nursing planning. Further practical applications are calculation of the costs of nursing care (using a classification of residents), measurement and transparency of nursing home quality (using quality indicators) and epidemiological surveys (using uniform data from assessments). The RAI is used nationwide in the USA, to some extent in other countries and in Germany predominantly in the context of research. The paper briefly describes the historical development of the different RAI variations (particularly with respect to the MDS), presents the central utilization options and ends with a critical discussion of possibilities and limits of the RAI.

Cost drivers of inpatient mental health care: a systematic review

Aims. New reimbursement schemes for inpatient mental health care are imminent in the UK and Germany. The shared intention is to reflect cost differences between patients in reimbursement rates. This requires understanding of patient characteristics that influence hospital resource use. The aim of this review was to show which associations between mental health care per diem hospital costs and patient characteristics are supported by current evidence. Methods. A systematic review of the literature published between 1980 and 2012 was carried out. The search strategy included electronic databases and hand-searching. Furthermore, reference lists, citing articles and related publications were screened and experts were contacted. Results. The search found eight studies. Dispersion in per diem costs was moderate, as was the ability to explain it with patient characteristics. Six patient characteristics were identified as the most relevant variables. These were (1) age, (2) major diagnostic group, (3) risk, (4) legal problems, (5) the ability to perform activities of daily living and (6) presence of psychotic or affective symptoms. Two non-patient-related factors were identified. These were (1) day of stay and (2) treatment site. Conclusions. Idiosyncrasies of mental health care complicated the prediction of per diem hospital costs. More research is required in European settings since transferability of results is unlikely.

Characteristics of Long-Term–Care Facility Residents Associated With Receipt of Influenza and Pneumococcal Vaccinations

Background:

Studies have found residency in long-term–care facilities (LTCFs) a risk factor for influenza and pneumonia and have demonstrated that vaccinations against these diseases reduce the risk of disease. However, rates are below Healthy People 2010 goals of 90% for LTCFs. During 1999–2002, a multi-state demonstration project was conducted in LTCFs to implement standing orders programs for immunizations.

Objective:

Identify nursing home resident–specific characteristics associated with vaccination coverage at baseline.

Methods:

Facility-level data were collected from self-reported surveys of selected nursing homes in 14 states and from the On-line Survey and Certification Reporting System. Resident-level data, including demographics and physical functioning, were obtained from the Centers for Medicare & Medicaid Services' Minimum Data Set; 2000–2001 vaccination status was obtained by chart review. Influenza vaccination status reflected a single season, whereas pneumococcal vaccination status reflected vaccination in the past. Multilevel analysis was used to control for facility-level variation.

Results:

Of 22,188 residents sampled in 249 LTCFs, complete data were obtained for 20,516 (92%). The average coverage for immunizations was 58.5% ± 0.7% for influenza and 34.6% ± 0.3% for pneumococcal. On bivariate analyses, residents with cognitive, psychiatric, or neurologic problems were more likely to be vaccinated; those with accidental injuries, unstable conditions, or cancer were less likely to receive either vaccine. On multilevel analysis, the strongest resident characteristics associated with receipt of immunizations, controlling facility variation, were cognitive deficits and psychiatric illness.

Conclusion:

The variation in baseline vaccination coverage associated with LTCF resident characteristics supports the need for strategies to increase vaccination coverage in LTCFs.

Contemplating case mix: A primer on case mix classification and management

Case mix classifications are the frameworks that underlie many healthcare funding schemes, including the so-called activity-based funding. Now more than ever, Canadian healthcare administrators are evaluating case mix-based funding and deciphering how they will influence their organization. Case mix is a topic fraught with technical jargon and largely relegated to government agencies or private industries. This article provides an abridged review of case mix classification as well as its implications for management in healthcare.

Antipsychotic medication use in nursing homes: a proposed measure of quality

OBJECTIVE

The potential misuse of antipsychotic medications (APMs) is an ongoing quality concern in nursing homes (NHs), especially given recent black box warnings and other evidence regarding the risk of APMs when used in NH populations. One mechanism regulators could use is public reporting of APM use by NHs; however, there is currently no agreed-upon measure of guideline-inconsistent APM use. In this paper, we describe a proposed measure of quality of APM use that is based on Centers for Medicare and Medicaid Services (CMS) Interpretive Guidelines, Food and Drug Administration (FDA) indications for APMs, and severity of behavioral symptoms.

METHODS

The proposed measure identifies NH residents who receive an APM but do not have an approved indication for APM use. We demonstrate the feasibility of this measure using data from Medicaid-eligible long-stay residents aged 65 years and older in seven states. Using multivariable logistic regressions, we compare it to the current CMS Nursing Home Compare quality measure.

RESULTS

We find that nearly 52% of residents receiving an APM lack indications approved by CMS/FDA guidelines compared with 85% for the current CMS quality measure. APM guideline-inconsistent use rates vary significantly across resident and facility characteristics, and states. Only our measure correlates with another quality indicator in that facilities with higher deficiencies have significantly higher odds of APM use. Predictors of inappropriate use are found to be consistent with other measures of NH quality, supporting the validity of our proposed measure.

CONCLUSION

The proposed measure provides an important foundation to improve APM prescribing practices without penalizing NHs when there are limited alternative treatments available.

Surveying multiple health professional team members within institutional settings: an example from the nursing home industry

Quality improvement and cost containment initiatives in health care increasingly involve interdisciplinary teams of providers. To understand organizational functioning, information is often needed from multiple members of a leadership team since no one person may have sufficient knowledge of all aspects of the organization. To minimize survey burden, it is ideal to ask unique questions of each member of the leadership team in areas of their expertise. However, this risks substantial missing data if all eligible members of the organization do not respond to the survey. Nursing home administrators (NHA) and directors of nursing (DoN) play important roles in the leadership of long-term care facilities. Surveys were administered to NHAs and DoNs from a random, nationally representative sample of U.S. nursing homes about the impact of state policies, market forces, and organizational factors that impact provider performance and residents' outcomes. Responses were obtained from a total of 2,686 facilities (response rate [RR] = 66.6%) in which at least one individual completed the questionnaire and 1,693 facilities (RR = 42.0%) in which both providers participated. No evidence of nonresponse bias was detected. A high-quality representative sample of two providers in a long-term care facility can be obtained. It is possible to optimize data collection by obtaining unique information about the organization from each provider while minimizing the number of items asked of each individual. However, sufficient resources must be available for follow-up to nonresponders with particular attention paid to lower resourced, lower quality facilities caring for higher acuity residents in highly competitive nursing home markets.

Providing more home-delivered meals is one way to keep older adults with low care needs out of nursing homes

Programs that help older adults live independently in the community can also deliver net savings to states on the costs of long-term supports and services. We estimate that if all states had increased by 1 percent the number of adults age sixty-five or older who received home-delivered meals in 2009 under Title III of the Older Americans Act, total annual savings to states' Medicaid programs could have exceeded $109 million. The projected savings primarily reflect decreased Medicaid spending for an estimated 1,722 older adults with low care needs who would no longer require nursing home care--instead, they could remain at home, sustained by home-delivered meals. Twenty-six states could have realized net savings in 2009 from the expansion of their home-delivered meals programs, while twenty-two states would have incurred net costs. Programs such as home-delivered meals have the potential to provide substantial savings to some states' Medicaid programs.

Is the Life Space Assessment applicable to a palliative care population? Its relationship to measures of performance and quality of life

CONTEXT

The spatial environments that palliative care patients frequent for business and leisure constrict as their disease progresses and their physical functioning deteriorates. Measuring a person's movement within his or her own environment is a clinically relevant and patient-centered outcome because it measures function in a way that reflects actual and not theoretical participation.

OBJECTIVES

This exploratory study set out to test whether the Life-Space Assessment (LSA) would correlate with other commonly used palliative care outcome measures of function and quality of life.

METHODS

The baseline LSA, Australia-modified Karnofsky Performance Status Scale (AKPS), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative (EORTC QLQ-C15-PAL) scores from two large clinical trials were used to calculate correlation coefficients between the measures. Convergent validity analysis was undertaken by comparing LSA scores between participants with higher (≥70) and lower (≤60) AKPS scores.

RESULTS

The LSA was correlated significantly and positively with the AKPS, with a moderate correlation coefficient of 0.54 (P<0.001). There was a significant weak negative correlation between the LSA and the EORTC QLQ-C15-PAL, with a small coefficient of -0.22 (P=0.027), but a strong correlation between the LSA and the EORTC QLQ-C15-PAL item related to independent activities of daily living (r=-0.654, P<0.01). A significant difference in the LSA score between participants with higher (≥70) and lower (≤60) AKPS scores t(97)=-4.35, P<0.001) was found.

CONCLUSION

The LSA appears applicable to palliative care populations given the convergent validity and capacity of this instrument to differentiate a person's ability to move through life-space zones by performance status. Further research is required to validate and apply the LSA within community palliative care populations.

Dual Eligibility, Selection of Skilled Nursing Facility, and Length of Medicare Paid Postacute Stay

Medicare and Medicaid dual-eligible beneficiaries use more medical care and experience worse health outcomes than Medicare-only beneficiaries. This article points to a possible inefficiency in the skilled nursing facility (SNF) admission process, specifically that patients and SNFs are partially matched based on dual-eligibility status, and investigates its influence on patients' SNF length of stay. Using a set of fee-for-service beneficiaries newly admitted for Medicare-paid SNF care, we document two findings: (1) compared with Medicare-only patients, dual-eligibles are more likely to be discharged to SNFs with low nurse-to-patient ratios and (2) dual-eligibles are more likely to become long-stay nursing home residents than Medicare-only beneficiaries if treated in SNFs with low nurse-to-patient ratios. We conclude that changes in the current SNF care referral process have the potential to reduce excess SNF utilization by dual-eligible beneficiaries and could help reduce spending by both Medicare and Medicaid.

Variations in levels of care between nursing home patients in a public health care system

Background

Within the setting of a public health service we analyse the distribution of resources between individuals in nursing homes funded by global budgets. Three questions are pursued. Firstly, whether there are systematic variations between nursing homes in the level of care given to patients. Secondly, whether such variations can be explained by nursing home characteristics. And thirdly, how individual need-related variables are associated with differences in the level of care given.

Methods

The study included 1204 residents in 35 nursing homes and extra care sheltered housing facilities. Direct time spent with patients was recorded. In average each patient received 14.8 hours direct care each week. Multilevel regression analysis is used to analyse the relationship between individual characteristics, nursing home characteristics and time spent with patients in nursing homes. The study setting is the city of Trondheim, with a population of approximately 180 000.

Results

There are large variations between nursing homes in the total amount of individual care given to patients. As much as 24 percent of the variation of individual care between patients could be explained by variation between nursing homes. Adjusting for structural nursing home characteristics did not substantially reduce the variation between nursing homes. As expected a negative association was found between individual care and case-mix, implying that at nursing home level a more resource demanding case-mix is compensated by lowering the average amount of care. At individual level ADL-disability is the strongest predictor for use of resources in nursing homes. For the average user one point increase in ADL-disability increases the use of resources with 27 percent.

Conclusion

In a financial reimbursement model for nursing homes with no adjustment for case-mix, the amount of care patients receive does not solely depend on the patients’ own needs, but also on the needs of all the other residents.

[Description of the clinical complexity of patients admitted to long term care hospitals in Catalonia during 2003-2009]

INTRODUCTION

This work describes the clinical complexity of patients admitted to long term care hospitals between 2003 and 2009.

MATERIAL AND METHODS

Cross-sectional analysis of Minimum Basic Dataset for Social and Healthcare Units information system data for 47,855 admissions. Outcomes assessed were functional and cognitive status, Resource Utilization Groups III (RUG-III), resource use categories, coverage and intensity of therapies, diagnosis, comorbidities, and medical procedures. Descriptive analyses were performed by year of admission.

RESULTS

Dementia and acute cerebrovascular disease were the most frequent primary diagnoses, and showed a steady decline over time (8.8% and 2.3% decline), while family respite admissions and fractures increased (7.7% and 1.9%, respectively). The average functional and cognitive status of the treated population was similar across all years, although individuals with dependence in each Activity of Daily Living increased. The most frequent resource use categories were rehabilitation, reduced physical function, clinically complex care, and special care. A sharp increase in rehabilitation was observed during the study period (20.3%), while the other categories decreased. Increasingly more patients received rehabilitation therapy during their hospital stay (20.8%). Coverage increased particularly for physiotherapy (25.4%) and occupational therapy (17.4%).

CONCLUSION

The clinical complexity faced by long term care hospitals increased during 2003- 2009. The use of resources and provision of therapies show an increasing rehabilitation effort, possibly as a response to changes in the clinical complexity of the treated population, the standards of care, or the established information reporting practices.

Influence of patient characteristics on care time in patients hospitalized with schizophrenia

BACKGROUND

In the current Japanese payment system for the treatment of psychiatric inpatients, the length of hospital stay and nurse staffing levels are key determinants of the amount of payment. These factors do not fully reflect the costs of care for each patient. The objective of this study was to clarify the relationship between patient characteristics and their care costs as measured by "care time" for patients with schizophrenia.

METHODS

Patient characteristics and care time were investigated in 14,557 inpatients in 102 psychiatric hospitals in Japan. Of these 14,557 inpatients, data for 8,379 with schizophrenia were analyzed using a tree-based model.

RESULTS

The factor exerting the greatest influence on care time was "length of stay", so subjects were divided into 2 groups, a "short stay group" with length of stay ≦104 days, and "long stay group" ≧105 days. Each group was further subdivided according to dependence with regard to "activities of daily living", "psychomotor agitation", "verbal abuse", and "frequent demands/repetitive complaints", which were critical variables affecting care time. The mean care time was shorter in the long-stay group; however, in some long-stay patients, the mean care time was considerably longer than that in patients in the short-stay group.

CONCLUSION

The results of this study suggest that it is necessary to construct a new payment system reflecting not only length of stay and nurse staffing levels, but also individual patient characteristics.

Scaling functional status within the interRAI suite of assessment instruments

Background

As one ages, physical, cognitive, and clinical problems accumulate and the pattern of loss follows a distinct progression. The first areas requiring outside support are the Instrumental Activities of Daily Living and over time there is a need for support in performing the Activities of Daily Living. Two new functional hierarchies are presented, an IADL hierarchical capacity scale and a combination scale integrating both IADL and ADL hierarchies.

Methods

A secondary analyses of data from a cross-national sample of community residing persons was conducted using 762,023 interRAI assessments. The development of the new IADL Hierarchy and a new IADL-ADL combined scale proceeded through a series of interrelated steps first examining individual IADL and ADL item scores among persons receiving home care and those living independently without services. A factor analysis demonstrated the overall continuity across the IADL-ADL continuum. Evidence of the validity of the scales was explored with associative analyses of factors such as a cross-country distributional analysis for persons in home care programs, a count of functional problems across the categories of the hierarchy, an assessment of the hours of informal and formal care received each week by persons in the different categories of the hierarchy, and finally, evaluation of the relationship between cognitive status and the hierarchical IADL-ADL assignments.

Results

Using items from interRAI’s suite of assessment instruments, two new functional scales were developed, the interRAI IADL Hierarchy Scale and the interRAI IADL-ADL Functional Hierarchy Scale. The IADL Hierarchy Scale consisted of 5 items, meal preparation, housework, shopping, finances and medications. The interRAI IADL-ADL Functional Hierarchy Scale was created through an amalgamation of the ADL Hierarchy (developed previously) and IADL Hierarchy Scales. These scales cover the spectrum of IADL and ADL challenges faced by persons in the community.

Conclusions

An integrated IADL and ADL functional assessment tool is valuable. The loss in these areas follows a general hierarchical pattern and with the interRAI IADL-ADL Functional Hierarchy Scale, this progression can be reliably and validly assessed. Used across settings within the health continuum, it allows for monitoring of individuals from relative independence through episodes of care.

Diagnostic data for neurological conditions in interRAI assessments in home care, nursing home and mental health care settings: a validity study

Background

The interRAI suite of assessment instruments can provide valuable information to support person-specific care planning across the continuum of care. Comprehensive clinical information is collected with these instruments, including disease diagnoses. In Canada, interRAI data holdings represent some of the largest repositories of clinical information in the country for persons with neurological conditions. This study examined the accuracy of the diagnostic information captured by interRAI instruments designed for use in the home care, long-term care and mental health care settings as compared with national administrative databases.

Methods

The interRAI assessments were matched with an inpatient hospital record and emergency department (ED) visit record in the preceding 90 days. Diagnoses captured on the interRAI instruments were compared to those recorded in either administrative record for each individual. Diagnostic validity was examined through sensitivity, specificity and positive predictive value analysis for the following conditions: multiple sclerosis, epilepsy, Alzheimer’s disease and other dementias, Parkinson’s disease, traumatic brain injury, stroke, diabetes mellitus, heart failure and reactive airway disease.

Results

In the three large study samples (home care: n = 128,448; long-term care: n = 26,644; mental health: n = 13,812), interRAI diagnoses demonstrated high specificity when compared to administrative records, for both neurological conditions (range 0.80 – 1.00) and comparative chronic diseases (range 0.83 – 1.00). Sensitivity and positive predictive values (PPV) were more varied by specific diagnosis, with sensitivities and PPV for neurological conditions ranging from 0.23 to 0.94 and 0.14 to 0.77, respectively. The interRAI assessments routinely captured more cases of the diagnoses of interest than the administrative records.

Conclusions

The interRAI assessment collected accurate information about disease diagnoses when compared to administrative records within three months. Such information is likely relevant to day-to-day care in these three environments and can be used to inform care planning and resource allocation decisions.

Effect of hospital-SNF referral linkages on rehospitalization

OBJECTIVE

To determine whether the rate of rehospitalization is lower among patients discharged to skilled nursing facilities (SNFs) with which a hospital has a strong linkage.

DATA SOURCES/COLLECTION

We used national Medicare enrollment, claims, and the Minimum Data Set to examine 2.8 million newly discharged patients to 15,063 SNFs from 2,477 general hospitals between 2004 and 2006.

STUDY DESIGN

We examined the relationship between the proportion of discharges from a hospital and alternative SNFs on the rehospitalization of patients treated by that hospital-SNF pair using an instrumental variable approach. We used distances to alternative SNFs from residence of the patients of the originating hospital as the instrument.

PRINCIPAL FINDINGS

Our estimates suggest that if the proportion of a hospital's discharges to an SNF was to increase by 10 percentage points, the likelihood of patients treated by that hospital-SNF pair to be rehospitalized within 30 days would decline by 1.2 percentage points, largely driven by fewer rehospitalizations within a week of hospital discharge.

CONCLUSIONS

Stronger hospital-SNF linkages, independent of hospital ownership, were found to reduce rehospitalization rates. As hospitals are held accountable for patients' outcomes postdischarge under the Affordable Care Act, hospitals may steer their patients preferentially to fewer SNFs.

Is There Extra Cost of Institutional Care for MS Patients?

Throughout life, patients with multiple sclerosis (MS) require increasing levels of support, rehabilitative services, and eventual skilled nursing facility (SNF) care. There are concerns that access to SNF care for MS patients is limited because of perceived higher costs of their care. This study compares costs of caring for an MS patient versus those of a typical SNF patient. We merged SNF cost report data with the 2001–2006 Nursing Home Minimum Data Set (MDS) to calculate percentage of MS residents-days and facility case-mix indices (CMIs). We estimated the average facility daily cost using hybrid cost functions, adjusted for facility ownership, average facility wages, CMI-adjusted number of SNF days, and percentage of MS residents-days. We describe specific characteristics of SNF with high and low MS volumes and examine any sources of variation in cost. MS patients were no longer more costly than typical SNF patients. A greater proportion of MS patients had no significant effect on facility daily costs (P = 0.26). MS patients were more likely to receive care in government-owned facilities (OR = 1.904) located in the Western (OR = 2.133) and Midwestern (OR = 1.3) parts of the USA (P < 0.05). Cost of SNF care is not a likely explanation for the perceived access barriers that MS patients face.

Impact of cigarette smoking on utilization of nursing home services

INTRODUCTION

Few studies have examined the effects of smoking on nursing home utilization, generally using poor data on smoking status. No previous study has distinguished utilization for recent from long-term quitters.

METHODS

Using the Health and Retirement Study, we assessed nursing home utilization by never-smokers, long-term quitters (quit >3 years), recent quitters (quit ≤3 years), and current smokers. We used logistic regression to evaluate the likelihood of a nursing home admission. For those with an admission, we used negative binomial regression on the number of nursing home nights. Finally, we employed zero-inflated negative binomial regression to estimate nights for the full sample.

RESULTS

Controlling for other variables, compared with never-smokers, long-term quitters have an odds ratio (OR) for nursing home admission of 1.18 (95% CI: 1.07-1.2), current smokers 1.39 (1.23-1.57), and recent quitters 1.55 (1.29-1.87). The probability of admission rises rapidly with age and is lower for African Americans and Hispanics, more affluent respondents, respondents with a spouse present in the home, and respondents with a living child. Given admission, smoking status is not associated with length of stay (LOS). LOS is longer for older respondents and women and shorter for more affluent respondents and those with spouses present.

CONCLUSIONS

Compared with otherwise identical never-smokers, former and current smokers have a significantly increased risk of nursing home admission. That recent quitters are at greatest risk of admission is consistent with evidence that many stop smoking because they are sick, often due to smoking.

Trends in postacute care and staffing in US nursing homes, 2001-2010

OBJECTIVE

The objective of this study was to document the growth of postacute care and contemporaneous staffing trends in US nursing homes over the decade 2001 to 2010.

DESIGN

We integrated data from all US nursing homes longitudinally to track annual changes in the levels of postacute care intensity, therapy staffing and direct-care staffing separately for freestanding and hospital-based facilities.

SETTING

All Medicare/Medicaid-certified nursing homes from 2001 to 2010 based on the Online Survey Certification and Reporting System database merged with facility-level case mix measures aggregated from resident-level information from the Minimum Data Set and Medicare Part A claims.

MEASUREMENTS

We created a number of aggregate case mix measures to approximate the intensity of postacute care per facility per year, including the proportion of SNF-covered person days, number of admissions per bed, and average RUG-based case mix index. We also created measures of average hours per resident day for physical and occupational therapists, PT/OT assistants, PT/OT aides, and direct-care nursing staff.

RESULTS

In freestanding nursing homes, all postacute care intensity measures increased considerably each year throughout the study period. In contrast, in hospital-based facilities, all but one of these measures decreased. Similarly, therapy staffing has risen substantially in freestanding homes but declined in hospital-based facilities. Postacute care case mix acuity appeared to correlate reasonably well with therapy staffing levels in both types of facilities.

CONCLUSION

There has been a marked and steady shift toward postacute care in the nursing home industry in the past decade, primarily in freestanding facilities, accompanied by increased therapy staffing.

Development of a case-mix funding system for adults with combined vision and hearing loss

Background

Adults with vision and hearing loss, or dual sensory loss (DSL), present with a wide range of needs and abilities. This creates many challenges when attempting to set the most appropriate and equitable funding levels. Case-mix (CM) funding models represent one method for understanding client characteristics that correlate with resource intensity.

Methods

A CM model was developed based on a derivation sample (n = 182) and tested with a replication sample (n = 135) of adults aged 18+ with known DSL who were living in the community. All items within the CM model came from a standardized, multidimensional assessment, the interRAI Community Health Assessment and the Deafblind Supplement. The main outcome was a summary of formal and informal service costs which included intervenor and interpreter support, in-home nursing, personal support and rehabilitation services. Informal costs were estimated based on a wage rate of half that for a professional service provider ($10/hour). Decision-tree analysis was used to create groups with homogeneous resource utilization.

Results

The resulting CM model had 9 terminal nodes. The CM index (CMI) showed a 35-fold range for total costs. In both the derivation and replication sample, 4 groups (out of a total of 18 or 22.2%) had a coefficient of variation value that exceeded the overall level of variation. Explained variance in the derivation sample was 67.7% for total costs versus 28.2% in the replication sample. A strong correlation was observed between the CMI values in the two samples (r = 0.82; p = 0.006).

Conclusions

The derived CM funding model for adults with DSL differentiates resource intensity across 9 main groups and in both datasets there is evidence that these CM groups appropriately identify clients based on need for formal and informal support.

An evaluation of data quality in Canada's Continuing Care Reporting System (CCRS): secondary analyses of Ontario data submitted between 1996 and 2011

Background

Evidence informed decision making in health policy development and clinical practice depends on the availability of valid and reliable data. The introduction of interRAI assessment systems in many countries has provided valuable new information that can be used to support case mix based payment systems, quality monitoring, outcome measurement and care planning. The Continuing Care Reporting System (CCRS) managed by the Canadian Institute for Health Information has served as a data repository supporting national implementation of the Resident Assessment Instrument (RAI 2.0) in Canada for more than 15 years. The present paper aims to evaluate data quality for the CCRS using an approach that may be generalizable to comparable data holdings internationally.

Methods

Data from the RAI 2.0 implementation in Complex Continuing Care (CCC) hospitals/units and Long Term Care (LTC) homes in Ontario were analyzed using various statistical techniques that provide evidence for trends in validity, reliability, and population attributes. Time series comparisons included evaluations of scale reliability, patterns of associations between items and scales that provide evidence about convergent validity, and measures of changes in population characteristics over time.

Results

Data quality with respect to reliability, validity, completeness and freedom from logical coding errors was consistently high for the CCRS in both CCC and LTC settings. The addition of logic checks further improved data quality in both settings. The only notable change of concern was a substantial inflation in the percentage of long term care home residents qualifying for the Special Rehabilitation level of the Resource Utilization Groups (RUG-III) case mix system after the adoption of that system as part of the payment system for LTC.

Conclusions

The CCRS provides a robust, high quality data source that may be used to inform policy, clinical practice and service delivery in Ontario. Only one area of concern was noted, and the statistical techniques employed here may be readily used to target organizations with data quality problems in that (or any other) area. There was also evidence that data quality was good in both CCC and LTC settings from the outset of implementation, meaning data may be used from the entire time series. The methods employed here may continue to be used to monitor data quality in this province over time and they provide a benchmark for comparisons with other jurisdictions implementing the RAI 2.0 in similar populations.

Antipsychotic use in nursing home residents admitted with hip fracture

OBJECTIVES

To evaluate the association between receiving antipsychotics and the outcomes of a cohort of nursing home (NH) residents with and without presumed delirium after hip fracture.

DESIGN

Population-based cohort study.

SETTING

Eleven thousand one hundred nineteen nursing homes nationwide from January 1, 2000, to December 31, 2007.

PARTICIPANTS

First-time NH admissions with hip fracture (n = 77,759).

MEASUREMENTS

The Nursing Home Confusion Assessment Method was used to identify residents with no delirium, subsyndromal delirium, and full delirium. Propensity score reweighting was used, with analyses stratified according to delirium level.

RESULTS

In subjects with no delirium symptoms, approximately 5% (n = 3,250) received antipsychotic drugs. These individuals were less likely to be discharged home (odds ratio (OR) = 0.68, P < .001), had a higher likelihood of death before nursing home discharge (OR = 1.28, P = .03), stayed in nursing homes longer (β 2.83, P = .05), and had less functional improvement at discharge (β -0.47, P = .03). Receipt of antipsychotics in participants with mild delirium was associated with a lower likelihood of discharge home (OR = 0.74, P = .03).

CONCLUSION

In NH residents with hip fracture and no delirium symptoms, use of antipsychotics was associated with worse outcomes, with the exception of rehospitalization. No clear benefits were associated with antipsychotic use for those with presumed delirium.

Older Persons' Transitions in Care (OPTIC): a study protocol

BACKGROUND

Changes in health status, triggered by events such as infections, falls, and geriatric syndromes, are common among nursing home (NH) residents and necessitate transitions between NHs and Emergency Departments (EDs). During transitions, residents frequently experience care that is delayed, unnecessary, not evidence-based, potentially unsafe, and fragmented. Furthermore, a high proportion of residents and their family caregivers report substantial unmet needs during transitions. This study is part of a program of research whose overall aim is to improve quality of care for frail older adults who reside in NHs. The purpose of this study is to identify successful transitions from multiple perspectives and to identify organizational and individual factors related to transition success, in order to inform improvements in care for frail elderly NH residents during transitions to and from acute care. Specific objectives are to: 1. define successful and unsuccessful elements of transitions from multiple perspectives; 2. develop and test a practical tool to assess transition success; 3. assess transition processes in a discrete set of transfers in two study sites over a one year period; 4. assess the influence of organizational factors in key practice locations, e.g., NHs, emergency medical services (EMS), and EDs, on transition success; and 5. identify opportunities for evidence-informed management and quality improvement decisions related to the management of NH - ED transitions.

METHODS/DESIGN

This is a mixed-methods observational study incorporating an integrated knowledge translation (IKT) approach. It uses data from multiple levels (facility, care unit, individual) and sources (healthcare providers, residents, health records, and administrative databases).

DISCUSSION

Key to study success is operationalizing the IKT approach by using a partnership model in which the OPTIC governance structure provides for team decision-makers and researchers to participate equally in developing study goals, design, data collection, analysis and implications of findings. As preliminary and ongoing study findings are developed, their implications for practice and policy in study settings will be discussed by the research team and shared with study site administrators and staff. The study is designed to investigate the complexities of transitions and to enhance the potential for successful and sustained improvement of these transitions.
