Functional outcomes of posthospital care for stroke and hip fracture patients under medicare

Recovery of activities of daily living in older adults after hospitalization for acute medical illness

OBJECTIVES

To compare functional outcomes in the year after discharge for older adults discharged from the hospital after an acute medical illness with a new or additional disability in their basic self-care activities of daily living (ADL) (compared with preadmission baseline 2 weeks before admission) with those of older adults discharged with baseline ADL function and identify predictors of failure to recover to baseline function 1 year after discharge.

DESIGN

Observational.

SETTING

Tertiary care hospital, community teaching hospital.

PARTICIPANTS

Older (aged >or=70) patients nonelectively admitted to general medical services (1993-1998).

MEASUREMENTS

Number of ADL disabilities at preadmission baseline and 1, 3, 6, and 12 months after discharge. Outcomes were death, sustained decline in ADL function, and recovery to baseline ADL function at each time point.

RESULTS

By 12 months after discharge, of those discharged with new or additional ADL disability, 41.3% died, 28.6% were alive but had not recovered to baseline function, and 30.1% were at baseline function. Of those discharged at baseline function, 17.8% died, 15.2% were alive but with worse than baseline function, and 67% were at their baseline function (P<.001). Of those discharged with new or additional ADL disability, the presence or absence of recovery by 1 month was associated with long-term outcomes. Age, cardiovascular disease, dementia, cancer, low albumin, and greater number of dependencies in instrumental ADLs independently predicted failure to recover.

CONCLUSION

For older adults discharged with new or additional disability in ADL after hospitalization for medical illness, prognosis for functional recovery is poor. Rehabilitation interventions of longer duration and timing than current reimbursement allows, caregiver support, and palliative care should be evaluated.

Care home versus hospital and own home environments for rehabilitation of older people

BACKGROUND

Rehabilitation for older people has acquired an increasingly important profile for both policy-makers and service providers within health and social care agencies. This has generated an increased interest in the use of alternative care environments including care home environments. Yet, there appears to be limited evidence on which to base decisions.This review is the first update of the Cochrane review which was published in 2003.

OBJECTIVES

To compare the effects of care home environments (e.g. nursing home, residential care home and nursing facilities) versus hospital environments and own home environments in the rehabilitation of older people.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Specialised Register and Pending Folder, MEDLINE (1950 to March Week 3 2007), EMBASE (1980 to 2007 Week 13), CINAHL (1982 to March, Week 4, 2007), other databases and reference lists of relevant review articles were additionally reviewed. Date of most recent search: March 2007.

SELECTION CRITERIA

Randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series (ITS) that compared rehabilitation outcomes for persons 60 years or older who received rehabilitation whilst residing in a care home with those who received rehabilitation in hospital or own home environments.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data.

MAIN RESULTS

In this update, 8365 references were retrieved. Of these, 339 abstracts were independently assessed by 2 review authors, and 56 studies and 5 review articles were subsequently obtained. Full text papers were independently assessed by two or three review authors and none of these met inclusion criteria.

AUTHORS' CONCLUSIONS

There is insufficient evidence to compare the effects of care home environments versus hospital environments or own home environments on older persons rehabilitation outcomes. Although the authors acknowledge that absence of effect is not no effect. There are three main reasons; the first is that the description and specification of the environment is often not clear; secondly, the components of the rehabilitation system within the given environments are not adequately specified and; thirdly, when the components are clearly specified they demonstrate that the control and intervention sites are not comparable with respect to the methodological criteria specified by Cochrane EPOC group. The combined effect of these factors resulted in the comparability between intervention and control groups being very weak.

The price of bouncing back: one-year mortality and payments for acute stroke patients with 30-day bounce-backs

OBJECTIVES

To examine 1-year mortality and healthcare payments of stroke patients experiencing zero, one and two or more bounce-backs within 30 days of discharge.

DESIGN

Retrospective analysis of administrative data.

SETTING

Four hundred twenty-two hospitals in the southern and eastern United States.

PARTICIPANTS

Eleven thousand seven hundred twenty-nine Medicare beneficiaries aged 65 and older surviving at least 30 days with acute ischemic stroke in 2000.

MEASUREMENTS

One-year mortality and predicted total healthcare payments were calculated using log-normal parametric survival analysis and quantile regression, respectively. Models included sociodemographics, prior medical history, stroke severity, length of stay, and discharge site.

RESULTS

Crude survival at 1 year for the zero, one and two or more bounce-back groups was 83%, 67%, and 55%, respectively. The one bounce-back group had 49% shorter (time ratio (TR)=0.51, 95% confidence interval (CI)=0.46-0.56) and the two or more bounce-backs group had 68% shorter (TR=0.32, 95% CI=0.27-0.38) adjusted 1-year survival time than the zero bounce-back group. For high- and low-cost patients, adjusted predicted payments were greater with each additional bounce-back experienced.

CONCLUSION

Acute stroke patients experiencing bounce-backs within 30 days have strikingly poorer survival and higher healthcare payments over the subsequent year than their counterparts with no bounce-backs. Bounce-backs may serve as a simple predictor for identifying stroke patients at extremely high risk for poor outcomes.

Modifications of the FIM instrument under the inpatient rehabilitation facility prospective payment system

OBJECTIVES

To describe the modifications made to the FIM instrument when it was incorporated into the Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI), and to compare FIM data collected before and after the IRF prospective payment system (IRF-PPS) was implemented in 2002 for patients with stroke.

DESIGN

Year-by-year comparison of data of Medicare patients with stroke discharged in 1998-2003 from 411 IRFs that submitted data to the Uniform Data System for Medical Rehabilitation for each of those years.

RESULTS

In the pre-PPS period, admission motor FIM ratings decreased slightly, and discharge motor, admission cognitive, and discharge cognitive ratings remained stable. Between 2001 and 2003, all four ratings decreased: admission motor by 1.8 FIM units, discharge motor by 3.3 FIM units, and admission and discharge cognitive each by 1.0 FIM unit. The lower admission FIM ratings led to an increase in the mean case-mix index from 1.39 to 1.49.

CONCLUSIONS

The decrease in FIM ratings in the IRF-PAI/PPS years may reflect alterations in coding practices as a result of changed rules for rating the FIM instrument, "downcoding" leading to assignment into higher-paying categories, changes in the IRF patient population, and/or changes in IRF patient outcomes. Coding changes should be considered when comparing pre-PPS and PPS FIM data.

Assessing the effectiveness of postacute care rehabilitation

This commentary reviews a number of issues related to determining the effectiveness of postacute care including what it is (in terms of type and site of care), how to tease out the critical elements (what components of this multifaceted process are essential), the role of research designs (given the logistic difficulties of doing randomized trials, how can nonexperimental designs be used to the greatest advantage), how to assess the relation between treatment and outcomes, measurement issues (what, when, how), correcting for case mix, and potential payment schemes.

Impact of an Inpatient Rehabilitation Facility on Functional Outcome and Length of Stay of Burn Survivors

This study reviewed the use of an inpatient rehabilitation unit for burn survivors. We hypothesized that adult burn patients admitted earlier to inpatient rehabilitation have an equal or better functional outcome than those remaining in acute burn center for rehabilitation care. Functional Independence Measure (FIM) data were prospectively collected on our burn center admissions dating January 2002 to August 2003. National rehabilitation data were acquired from eRehabData and burn literature. A total of 217 adult patients survived until hospital discharge, with 21 (9.7%) discharged to inpatient rehabilitation (REHAB). REHAB had larger burn injuries, more inhalation injuries, higher incidence hand/foot burns, and longer length of stay (LOS). REHAB had lower FIM upon rehabilitation facility admission than national averages but greater FIM improvement during comparable rehabilitation LOS. Although our earlier rehabilitation admission strategy results in more frequent rehabilitation unit referrals, patients had shorter burn center LOS and greater FIM improvement compared with limited national burn patient functional outcome data currently available.

How much is postacute care use affected by its availability?

OBJECTIVE

To assess the relative impact of clinical factors versus nonclinical factors-such as postacute care (PAC) supply-in determining whether patients receive care from skilled nursing facilities (SNFs) or inpatient rehabilitation facilities (IRFs) after discharge from acute care.

DATA SOURCES AND STUDY SETTING

Medicare acute hospital, IRF, and SNF claims provided data on PAC choices; predictors of site of PAC chosen were generated from Medicare claims, provider of services, enrollment file, and Area Resource File data.

STUDY DESIGN

We used multinomial logit models to predict PAC use by elderly patients after hospitalizations for stroke, hip fractures, or lower extremity joint replacements.

DATA COLLECTION/EXTRACTION METHODS

A file was constructed linking acute and postacute utilization data for all medicare patients hospitalized in 1999.

PRINCIPAL FINDINGS

PAC availability is a more powerful predictor of PAC use than the clinical characteristics in many of our models. The effects of distance to providers and supply of providers are particularly clear in the choice between IRF and SNF care. The farther away the nearest IRF is, and the closer the nearest SNF is, the less likely a patient is to go to an IRF. Similarly, the fewer IRFs, and the more SNFs, there are in the patient's area the less likely the patient is to go to an IRF. In addition, if the hospital from which the patient is discharged has a related IRF or a related SNF the patient is more likely to go there.

CONCLUSIONS

We find that the availability of PAC is a major determinant of whether patients use such care and which type of PAC facility they use. Further research is needed in order to evaluate whether these findings indicate that a greater supply of PAC leads to both higher use of institutional care and better outcomes-or whether it leads to unwarranted expenditures of resources and delays in returning patients to their homes.

Significance of poor patient participation in physical and occupational therapy for functional outcome and length of stay

OBJECTIVES

To determine the frequency of poor patient participation during inpatient physical (PT) and occupational therapy (OT) sessions and to examine the influence of poor participation on functional outcome and length of stay (LOS).

DESIGN

Prospective observational study.

SETTING

University-based, freestanding acute rehabilitation hospital.

PARTICIPANTS

Two hundred forty-two inpatients, primarily elderly (age range, 20-96y), with a variety of impairment diagnoses (eg, stroke), who were admitted for inpatient rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The Pittsburgh Rehabilitation Participation Scale, the 13 motor items from the FIM instrument (FIM motor), LOS, and discharge disposition.

RESULTS

We categorized the sample into 3 groups: "good" participators were those for whom all inpatient PT and OT sessions were rated 4 or greater (n=139), "occasional poor" participators were those with less than 25% of scores rated below 4 (n=53), and "frequent poor" participators were those with 25% or more of scores rated below 4 (n=50). Change in FIM motor scores during the inpatient rehabilitation stay was significantly better for good and occasional poor participators, compared with frequent poor participators (mean FIM improvement: 23.2, 22.8, and 17.6, respectively; repeated-measures analysis of variance group by time interaction, P <.002). LOS was significantly longer for occasional poor participators, compared with good and frequent poor participators controlling for admission FIM differences (adjusted means: 13.9d, 11.0d, and 10.9d, respectively; analysis of covariance, P <.001).

CONCLUSIONS

Poor participation in therapy is common during inpatient rehabilitation and has important clinical implications, in terms of lower improvement in FIM scores and longer LOS. These results suggest that poor inpatient rehabilitation participation and its antecedents deserve further attention.

The HORIZON Recurrent Fracture Trial: design of a clinical trial in the prevention of subsequent fractures after low trauma hip fracture repair

OBJECTIVE

To present the novel design of a trial testing the safety and efficacy of a yearly bisphosponate, zoledronic acid, in preventing new clinical fractures in patients with recent low trauma hip fracture repair.

RESEARCH DESIGN AND METHODS

Randomized, placebo-controlled, triple-blind study. One hundred and fifteen clinical centers worldwide are recruiting approximately 1714 subjects aged 50 years and over (no upper age limit, median age of enrolled subjects to date 79 years) who have undergone surgical repair of a low trauma hip fracture in the preceding 90 days. Patients will be assigned at random to an intervention group (5 mg zoledronic acid intravenously yearly) or a control group (placebo infusion yearly). Both groups receive a loading dose of Vitamin D2 or D3 IM or orally, followed by 800-1200 IU Vitamin D and 1000-1500 mg elemental calcium orally on a daily basis. Concomitant therapy with calcitonin, hormone replacement therapy, selective estrogen receptor modulators, tibolone, and external hip protectors are allowed.

MAIN OUTCOME MEASURES

The primary endpoint is subsequent skeletal fractures as adjudicated by a clinical endpoints committee blinded to intervention status. Secondary outcomes include delayed hip fracture healing, changes in bone mineral density, and health resource utilization. Subjects will be recruited over a 3-4 year period and will be followed until 211 primary endpoints are accrued and adjudicated.

CONCLUSIONS

This randomized clinical trial is novel among osteoporosis therapies as it (1). targets hip fracture patients, a previously understudied group, and (2). uses only clinically evident fractures as the primary outcome. Ethical and practical considerations in studying this frail population are discussed.

Does Payment Structure Influence Change in Physical Functioning After Rehabilitation Therapy?

PURPOSE

To determine if there are differences by payment structure (Medicare managed care versus fee-for-service) in the duration and intensity of geriatric rehabilitation therapy treatments and measure their effect on change in physical functioning at discharge.

METHODS

Sixty-eight Medicare managed care (MCO) and 32 fee-for-service (FFS) subjects from 3 skilled nursing facilities (SNFs) in Southern California answered the physical functioning dimension of the Sickness Impact Profile (SIP-PFD) before and after rehabilitation therapy. Patient characteristics at admission, therapy treatments, and discharge physical functioning were compared by payment structure using chi-square and t-tests; logistic and ordinary least squares (OLS) regressions were employed to determine significant predictors of enrollment in managed care and change in physical functioning at discharge.

RESULTS

Payment structure yielded no significant differences in patient characteristics (physical functioning, socio-demographics, and clinical characteristics) at admission to rehabilitation. Compared to MCO subjects, FFS subjects received significantly more minutes per day (intensity) of rehabilitation therapy (Mean difference = - 16.90; t-test = - 4.504; p =.000). On average, all subjects reported significant, positive change in physical functioning from admission to discharge after rehabilitation (Mean change = 7.98, SD = 12.96; t-test = 6.157; p =.000); but change in physical functioning between MCO and FFS subjects was not significant.

CONCLUSIONS

Payment structure did not significantly influence change in physical functioning at discharge. Future studies, using a larger sample- size, should consider the effects of structural elements, process, and patient behavior on therapy treatments and physical functioning outcomes.

Case study of hip fracture in an older person

PURPOSE

To discuss proximal femoral (hip) fractures as the leading cause of hospitalization for injuries among older persons, using a case example that illustrates not only the orthopedic injury but also how an older person's chronic problems complicate the acute event.

DATA SOURCES

Extensive review of scientific literature on the conditions discussed, supplemented by the case study.

CONCLUSIONS

Hip fractures in older adults can present multiple challenges to care when complicated by preexisting or coexisting conditions. This case of an older man with a hip fracture emphasizes the resuscitation priorities for the patient found after a "long lie" and the impact of chronic alcoholism and malnutrition, which lead to serious complications.

IMPLICATIONS FOR PRACTICE

Careful physical and psychosocial assessment is important for determining the presenting problem and comorbid conditions. Priorities for postoperative management of hip fracture and its complications guide the nurse practitioner through the successful return of the patient to the community.

The contribution of hip fracture to risk of subsequent fractures: data from two longitudinal studies

BACKGROUND

The contribution of hip fracture to the risk of subsequent fractures is unclear.

METHODS

Data from the Baltimore Hip Studies and the Established Populations for Epidemiologic Studies of the Elderly (EPESE) were used. Baltimore subjects enrolled at the time of hip fracture ( n=549) and EPESE subjects without previous fractures at baseline ( n=10,680) were followed for 2-10 years. Self-reported nonhip skeletal fracture was the outcome, and hip fracture was a time-varying covariate in a survival analysis stratified by study site. The model was adjusted for race, sex, age, BMI, stroke, cancer, difficulty walking across a room, dependence in grooming, dependence in transferring, and cognitive impairment.

RESULTS

The rate of all subsequent self-reported fractures after hip fracture was 10.4 fractures/100 person-years. The unadjusted hazard of nonhip skeletal fracture was 2.52 (95% confidence interval 2.05 to 3.12) for subjects with hip fracture compared with subjects without; when adjusted for other known fracture risk factors the hazard ratio was 1.62 (1.30 to 2.02). Men and women had a similar relative risk increase. The increased risk of secondary fracture after hip fracture persisted over time.

CONCLUSIONS

A hip fracture is associated with a 2.5-fold increased risk of subsequent fracture, which is not entirely explained by prefracture risk factors. Careful attention to secondary prevention is warranted in these patients.

Care home versus hospital and own home environments for rehabilitation of older people

BACKGROUND

Rehabilitation for older people has acquired an increasingly important profile for both policy-makers and service providers within health and social care agencies. This growing demand for rehabilitation services has generated an increased interest in the use of alternative care environments, for example care home environments, for older persons' rehabilitation. At a time when there is pressure for policy decision-makers and service providers to explore the use of such care settings for the provision of rehabilitation for older people, there appears limited evidence on which to base decisions.

OBJECTIVES

The objective of this review is to compare the effects of care home environments (e.g. nursing home, residential care home and nursing facilities) versus hospital environments and own home environments in the rehabilitation of older people.

SEARCH STRATEGY

The following databases were searched. The Cochrane Effective Practice and Organisation of Care Specialised Register, the Cochrane Rehabilitation Specialist Register; Cochrane Controlled Trials Register (CCTR); MEDLINE (1966-2000); EMBASE (1980-2000), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982-2000): Science Citation Index (1982-2000); Social Science Citation Index (1982-2000); Best Evidence (1991-2000); HMIC (1979-2000); PsycINFO(1967-2000); ASSIA (1987-2000); Ageline (1978-2000); AgeInfo (1971-2000); Sociological Abstracts (1963-2000); System for Information on Grey Literature (SIGLE) (1980-2000); UK National Research Registers Project Database( Issue 1 2001); Architecture Publication Index (1977-2000). The following Journals were hand searched: Disability and Rehabilitation (1992-2000); Disability and Society (1986-2000); Archives of Physical Medicine and Rehabilitation (1985-2000); Journal of the American Geriatric Society (1980-2000); International Journal of Rehabilitation Research (1980-2000); American Journal of Physical Medicine and Rehabilitation (1980-2000) and: Clinical Rehabilitation (1992-2000). The reviewers also consulted subject area experts and obtained full text review articles and forward tracked any references from these sources.

SELECTION CRITERIA

Randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series (ITS) that compared rehabilitation outcomes for persons 60 years or older who received rehabilitation whilst residing in a care home with those for persons 60 years or older who received rehabilitation in hospital or own home environments. Primary outcomes included functional outcomes using activities of daily living measurement (both personal and instrumental). Secondary outcomes included subjective health status; quality of life measures; return to place of usual residency; all cause mortality; adverse effects; readmission to an acute care facility; patient and carer satisfaction; number of days in facility and number of days receiving rehabilitation.

DATA COLLECTION AND ANALYSIS

One reviewer (DW) completed the initial search and identified potential papers for inclusion. Abstracts for these papers were independently scrutinised by two reviewers (DW/MS) to assess their eligibility. Full text versions of potentially eligible papers were independently assessed by two reviewers (DW/MS). Papers that fulfilled the comparison inclusion criteria were then independently scrutinised by all reviewers to assess whether they met EPOC methodological criteria for inclusion.

MAIN RESULTS

The total yield from the initial search strategy was 19,457. A total of 1,247 abstracts were independently scrutinised by two reviewers (DW/MS) to assess their eligibility. Full text papers for 99 studies were obtained to assess if they fulfilled the review's comparison inclusion criteria. This process resulted in 12 papers being assessed further for methodological validity. However, none of these studies met the inclusion criteria.

REVIEWER'S CONCLUSIONS

There is insufficient evidence to compare the effects of care home environments, hospital environments and own home environments on older persons rehabilitation outcomes. Although the authors acknowledge that absence of effect is not no effect. There are three main reasons; the first is that the description and specification of the environment is often not clear; secondly, the components of the rehabilitation system within the given environments are not adequately specified and; thirdly, when the components are clearly specified they demonstrate that the control and intervention sites are not comparable with respect to the methodological criteria specified by Cochrane EPOC group (Cochrane 1998). The combined effect of these factors resulted in the comparability between intervention and control groups being very weak. For example, there were differences in the services provided in the intervention and control arms, due possibly to differences in dominant remuneration systems, nature of the rehabilitation transformation, patient characteristics, skill mix and academic status of the care environment.

Functional gains and therapy intensity during subacute rehabilitation: a study of 20 facilities

OBJECTIVES

To document patient, program characteristics, and therapy service provision in subacute rehabilitation across 3 types of facilities that provide subacute rehabilitation, to examine the determinants of therapy intensity, and to evaluate the contribution of rehabilitation services to functional gains.

DESIGN

A retrospective study linking administrative billing data and patients' functional assessment records.

SETTING

Twenty facilities part of the Uniform Data System for Medical Rehabilitation (UDSMR) subacute database

PARTICIPANTS

A total of 1976 billing records of patients with stroke, orthopedic, and debility impairments, discharged in 1996 and 1997, were retrieved and linked with the FIM trade mark instrument ratings from UDSMR subacute database.

INTERVENTIONS

Not applicable.

MAIN OUTCOMES MEASURES

Total therapy intensity and Rasch-transformed FIM domain gains (ie, gains in self-care, mobility, cognition).

RESULTS

Therapy intensity was mostly determined by impairment and facility type, although variances explained by the predictors were small. Patients in all 3 impairment groups made functional gains; gains were related weakly, although significantly, to therapy intensity and rehabilitation duration after controlling for other variables.

CONCLUSIONS

The provision of rehabilitation therapies varied across facilities. Skilled nursing facilities with subacute rehabilitation units tended to provide more therapies than subacute units in acute or rehabilitation hospitals.

Structure, process, and outcomes in stroke rehabilitation

BACKGROUND

The health services research framework of structure, process, and outcome is used commonly to examine quality of care, and it indicates that structure influences process, which in turn influences outcomes. However, little empirical work has been done to test this hypothesis, particularly for medical rehabilitation.

OBJECTIVES

To determine if, among stroke patients, (1) structure of care was associated with process of care, and (2) structure of care was associated with outcomes after adjusting for process.

RESEARCH DESIGN

Two-year, prospective study of 288 acute stroke patients in 11 VA medical centers, of whom 128 were included in the current analysis.

MEASURES

Structure of care: systemic organization, staffing expertise, and technological sophistication. Process of care: compliance with the AHCPR poststroke rehabilitation guidelines.

PATIENT CHARACTERISTICS

baseline prior walking ability and Functional Independence Measure (FIM) motor subscale.

OUTCOMES

the FIM motor subscale 6-months poststroke.

RESULTS

The combination of systemic organization and staffing expertise, along with technological sophistication, were independent predictors of process of care (beta coefficients 0.21, P<0.05 and 0.37, P<0.001, respectively). When controlling simultaneously for patient characteristics, structure and process of care, structure of care did not have and process of care did have a statistically significant association (beta coefficient 0.18, P<0.01) with functional outcomes.

CONCLUSIONS

Better process of care was associated with better 6-month functional outcomes, therefore improving process of care probably would improve stroke outcomes. However, our results indicate that improving key structure of care elements might facilitate improving process of care for stroke patients.

The impact of the 1997 Balanced Budget Amendment's prospective payment system on patient case mix and rehabilitation utilization in skilled nursing

PURPOSE

This study examines the impact of the post-acute prospective payment system (PPS) on Medicare-funded rehabilitation services in skilled nursing facilities (SNFs) and whether such impact varies under different payment mechanisms.

DESIGN AND METHODS

We interviewed 214 Medicare beneficiaries admitted to three SNFs in southern California for rehabilitation. We compared patients' admission characteristics and therapy utilization among those receiving post-acute rehabilitation before and after the implementation of PPS.

RESULTS

Patients admitted after PPS implementation were more likely to have orthopedic problems or stroke and poorer self-reported physical health. They had significantly shorter lengths of stay in rehabilitation and received significantly less therapy, although those in managed care had less reduction in treatment after SNF-PPS implementation than those in fee-for-service.

IMPLICATIONS

After SNF-PPS implementation, rehabilitation treatment levels in the study sites were reduced. Whereas changes in Medicare managed care were comparatively modest, we observed significant changes in intensity and duration of physical and occupational therapies in Medicare fee-for-service.

Clinical challenges in the care of frail older persons

The clinical challenges of meeting the needs of frail older persons are essentially those encompassed by chronic disease multiplied by the special problems presented by aging, namely the presentation and management of disease and the special syndromes associated with geriatrics. The need to develop an approach to the care of frail older persons reflects a more general need to address system reform for chronic disease. The steps include new roles for patients and their families, the use of information technology to monitor changes in patients' status more continuously and to intervene in a more timely way, and a re-evaluation of the use of personnel at all levels. At present, we know more about how to deliver effective chronic care than we practice. The barriers to implementation include both a general reluctance to change and negative financial incentives to implement what has been shown to be effective.

Adherence to postacute rehabilitation guidelines is associated with functional recovery in stroke

BACKGROUND AND PURPOSE

The purpose of this study was to determine if compliance with poststroke rehabilitation guidelines was associated with better functional outcomes.

METHODS

An inception cohort of 288 stroke patients in 11 Department of Veteran Affairs Medical Centers hospitalized between January 1998 and March 1999 were followed prospectively for 6 months. Data were abstracted from medical records and telephone interviews. The primary study outcome was the Functional Independence Motor Score (FIM). Secondary outcomes included Instrumental Activities of Daily Living (IADL), SF-36 physical functioning, and the Stroke Impact Scale (SIS). Acute and postacute rehabilitation guideline compliance scores (range 0 to 100) were derived from an algorithm. All outcomes were adjusted for case-mix.

RESULTS

Average compliance scores in acute and postacute care settings were 68.2% (SD 14) and 69.5% (SD 14.4), respectively. After case-mix adjustment, level of compliance with postacute rehabilitation guidelines was significantly associated with FIM motor, IADL, and the SIS physical domain scores. SF-36 physical function was not associated with guideline compliance. Level of compliance with rehabilitation guidelines in acute settings was unrelated to any of the outcome measures.

CONCLUSION

Greater levels of adherence to postacute stroke rehabilitation guidelines were associated with improved patient outcomes. Compliance with guidelines may be viewed as a quality-of-care indicator with which to evaluate new organizational and funding changes involving postacute stroke rehabilitation.

Outcomes and secondary prevention strategies for male hip fractures

OBJECTIVE

To assess clinical outcomes and determine whether osteoporosis assessment and secondary prevention strategies were performed for male veterans hospitalized for hip fractures.

DESIGN

Retrospective chart review for male veterans hospitalized for hip fracture from January 1993 through July 1999.

SETTING

The Veterans Affairs Medical Center, Madison, WI.

RESULTS

Medical charts were available for 46 of 53 male patients admitted for hip fracture during the study period. Three subjects were excluded because hip fracture was associated with high-impact trauma. Mean age of the 43 study patients was 72 years (range 43-91 y), and mean length of hospitalization was 16 days (median 11 d, range 3-108 d). Thirty-two (82%) of 39 veterans whose disposition was documented were discharged to a nursing home. Eleven (26%) of 43 men died within 12 months after fracture. Twelve (28%) had fractured previously. Four (10%) subsequently had another fracture. Three of 9 patients with documented ambulation status were ambulatory at 1 year. Three patients received a bone mass measurement within a prespecified time interval of 6 months subsequent to fracture. No patient's records included a diagnosis of osteoporosis either before or within 6 months after fracture. One-third of the patients had documentation of calcium or multivitamin supplementation at discharge. One patient was receiving calcitonin at the time of fracture and continued to receive it afterward. No other patient was prescribed antiresorptive therapy by the time of hospital discharge.

CONCLUSIONS

Male veterans with hip fractures received inadequate evaluation and treatment for osteoporosis, although a substantial portion had documentation of recurrent fractures. Education of clinicians and creation of algorithms for management of established osteoporosis may improve outcomes for these individuals.

Effects of using consumer and expert ratings of an activities of daily living scale on predicting functional outcomes of postacute care

To test the effects of using preference weights for activities of daily living (ADL) outcome measures derived from different sources, data from a large study of the outcomes of postacute care (PAC study) were analyzed using two different weightings for the ADL measures. Both were developed using the same magnitude estimation technique; one from a panel of long-term care experts (the expert rating system); the other from a group of elderly Medicare beneficiaries (the consumer rating system). Neither group was directly involved in the PAC study. Although ADL scores generated by both rating systems were highly correlated prior to hospitalization and at hospital discharge, the consumer and expert rating systems generated significantly different functional outcomes measured by the change of ADL scores with a few exceptions. Compared to the consumer rating system, the expert rating system generated a greater change in functional outcomes at each of three follow-up time points after hospital discharge. This study suggests that the choice of weights for ADL items is important.

Patterns of rehabilitation utilization after hip fracture in acute hospitals and skilled nursing facilities

BACKGROUND

Hospitalized hip fracture patients may receive physical therapy (PT) in acute and/or postacute settings. Patterns of PT use may vary by patient, clinical, and hospital characteristics. These patterns can be analyzed if the acute and postacute stays are linked.

OBJECTIVES

We classified the following patterns of PT use: acute PT only, skilled nursing facility (SNF) PT only, acute and SNF PT, and no PT. For each pattern, we compared (1) characteristics of hip fracture patients, (2) length of stay (LOS), and (3) discharge outcomes.

SUBJECTS

The study included 187,990 hospitalized hip fracture patients derived from Medicare administrative data.

MEASURES

Dependent variables were PT use patterns, acute hospital and SNF LOS, total episode days of care, and discharge destination. Independent variables were demographic, clinical, and facility characteristics. PT use patterns were also used as independent variables in the LOS and discharge destination models.

RESULTS

Patterns of PT use were influenced by demographic and clinical characteristics such as age, race, and surgery type. Similarly, different LOS measures and discharge destinations varied by the PT use patterns. Patients receiving acute PT had longer acute LOSs; however, those patients who were subsequently transferred to SNFs had shorter SNF LOSs and total episode days of care. Patients utilizing PT were more likely to be discharged to home after the acute or SNF stay.

CONCLUSIONS

Disparities in PT use exist for subgroups of patients such as the elderly and blacks. Providers should determine the most appropriate setting for initiation of PT to achieve better discharge outcomes with efficient use of resources.

The Minnesota model of subacute care

HealthPartners, a nonprofit managed care organization in Minneapolis, Minn., has developed an integrated system of care for seniors in clinics, hospitals, and subacute care centers. The organization contracts for subacute care with a few skilled nursing facilities distributed throughout the area. Concentration of patients in these facilities allows for the presence of a nurse-practitioner on site. The nurse-practitioner collaborates with a geriatrician to provide care for 15 to 20 seniors. This team uses principles of geriatric assessment to optimize utilization and outcomes for frail seniors.

Normative treatment guidelines in home care: building the case

To effectively market programs and maximize resources under a prospective payment system, home healthcare agencies need to look closely at standardizing treatment practices to link patient outcomes to the care provided. This article discusses the issues, methods, and processes used to test treatment guidelines and strategies to improve existing guidelines through evidence-based research.

Therapy use and discharge outcomes for elderly nursing home residents

This study examines therapy use and discharge outcomes (community discharge, mortality, or remaining in the facility) over a 90-day period for 1,419 elderly, post-acute care nursing home admissions in South Dakota. Subjects met criteria as rehabilitation candidates (i.e., absence of serious behavioral or medical conditions that would limit rehabilitation potential). Receipt of therapies was related significantly to age (younger), Medicare coverage, hip fracture or stroke diagnosis, absence of cancer diagnosis, and resident or staff expectations for functional improvement. Therapy use was related positively to community discharge and negatively to mortality when controlling for covariates such as age, marital status, payment source, functional status, cognitive status, and major diagnoses. Also, community discharge was related positively to the facility's volume of therapy provision and percentage of Medicare-covered stays.

Non-pharmacological interventions

The aim of non-pharmacological intervention for osteoporosis is to prevent, treat or alleviate the consequences of osteoporosis, the main one of which is fracture. Non-pharmacological interventions consist of a wide spectrum of treatment modalities to decrease pain, correct postural change, improve mobility, enable the patient to follow a normal social life and prevent (further) fracture. An exercise programme can increase bone mass in adolescents and adults, but in the elderly its main emphasis should be on improving muscle strength and balance in order to decrease the risk of falls. Physiotherapy is commonly prescribed to mobilize the patient after a fracture, to decrease muscle spasm and pain, and to improve balance and co-ordination. An orthesis or back support may be used to correct kyphosis and decrease pain. Medication for pain is often needed and should cover both acute severe pain following fracture and chronic pain caused by postural change. A hip fracture is the most severe consequence of osteoporosis. The risk of hip fracture can be decreased by pharmacological treatment to increase bone mass and bone strength. However, in the very elderly the occurrence of falling may be more important than the failure of bone strength. Hip protectors have recently become available and have been shown to decrease the risk of hip fracture after a fall. These shunt the energy from the trochanter away to the sides. Non-pharmacological approaches to treatment are often neglected in daily practice, the emphasis being instead on treatment with drugs that decrease bone resorption and thereby increase bone strength.

Quality of life related to fear of falling and hip fracture in older women: a time trade off study

OBJECTIVE

To estimate the utility (preference for health) associated with hip fracture and fear of falling among older women.

DESIGN

Quality of life survey with the time trade off technique. The technique derives an estimate of preference for health states by finding the point at which respondents show no preference between a longer but lower quality of life and a shorter time in full health.

SETTING

A randomised trial of external hip protectors for older women at risk of hip fracture.

PARTICIPANTS

194 women aged >/= 75 years enrolled in the randomised controlled trial or who were eligible for the trial but refused completed a quality of life interview face to face.

OUTCOME MEASURES

Respondents were asked to rate their own health by using the Euroqol instrument and then rate three health states (fear of falling, a "good" hip fracture, and a "bad" hip fracture) by using time trade off technique.

RESULTS

On an interval scale between 0 (death) and 1 (full health), a "bad" hip fracture (which results in admission to a nursing home) was valued at 0.05; a "good" hip fracture (maintaining independent living in the community) 0.31, and fear of falling 0.67. Of women surveyed, 80% would rather be dead (utility=0) than experience the loss of independence and quality of life that results from a bad hip fracture and subsequent admission to a nursing home. The differences in mean utility weights between the trial groups and the refusers were not significant. A test-retest study on 36 women found that the results were reliable with correlation coefficients within classes ranging from 0.61 to 0.88.

CONCLUSIONS

Among older women who have exceeded average life expectancy, quality of life is profoundly threatened by falls and hip fractures. Older women place a very high marginal value on their health. Any loss of ability to live independently in the community has a considerable detrimental effect on their quality of life.

A classification scheme for outcome indicators

PURPOSE

To provide a framework for classifying outcome indicators for a more comprehensive view of outcomes and quality.

METHODS

Review of outcomes literature published since 1974 from medicine, nursing, and health services research to identify indicators. Outcome indicators were clustered inductively.

FINDINGS

Three groups of outcome indicators were identified: patient-focused, provider-focused, and organization-focused. Although investigators tend to focus on a select few outcome indicators, such as patient satisfaction, quality of life, and mortality, many indicators exist to measure outcomes.

CONCLUSIONS

Selecting and integrating a wide array of outcome indicators from the various categories will provide a more balanced view of health care delivery as compared with focusing on a few common indicators or only one category.
