Development of the nursing home Resident Assessment Instrument in the USA.

BACKGROUND: the nursing home Resident Assessment Instrument (RAI) includes a set of core assessment items, known as the Minimum Data Set (MDS), for assessment and care screening and more detailed Resident Assessment Protocols in 18 areas that represent common problem areas or risk factors for nursing home residents. Its primary use is clinical, to assess residents on admission to the nursing home, at least annually thereafter and on any significant change in status and to develop individualized, restorative plans of care. AIM: to describe the content and development of the RAI, including US testing for MDS item reliability and validity of the RAI, and the results of a 4-year evaluation of the effects of its clinical use. CONCLUSIONS: the evaluation found that implementation of the RAI was associated with significant improvements in a variety of measures of process quality, resident functional outcomes and reduced hospitalization. Other uses of the RAI data in the USA-including payment using resident classification systems and, with RAI-based outcome-oriented quality indicators, quality assurance activities-and the status of RAI use in other countries are also summarized.

Rehabilitation in nursing homes: a cross-national comparison of recipients.

OBJECTIVE: to examine the prevalence of therapy use in nursing homes in selected countries and to describe the characteristics of nursing home residents who receive therapy. DESIGN and SAMPLING: the design of the study is cross-sectional, using Minimum Data Set (MDS) assessments of nursing home residents. The sample includes all nursing home residents in six US states (n = 273491), in Copenhagen, Denmark (n = 3451), Reyjkavik, Iceland (n = 1254), and selected locations in Italy (n = 1089) and Japan (n = 1255). METHOD: we determined who had received physical or occupational therapy treatments in the last 7 days. Demographic and clinical characteristics of recipients were compared relative to other nursing home residents within each country. RESULTS: in the five countries, the prevalence of receiving therapy was 31% (Iceland), 30% Japan), 23% (Denmark), 14% (Italy) and 11% (USA). Substantial proportions of the recipients were over the age of 85, were clinically stable and had been in the nursing home for longer than 90 days. Across all countries, residents with poorer activities of daily living (ADL) scores but good cognitive scores were more likely to receive therapy than other residents. Rehabilitation nursing, an adjunct to therapy, was concentrated on residents with poor ADL scores. CONCLUSIONS: substantial numbers of long-stay residents receive therapy in nursing homes, including those over the age of 85 years and those with cognitive impairment. Hence, future rehabilitation outcome studies can involve these previously understudied patient populations.

Comparisons of restraint use in nursing homes in eight countries.

BACKGROUND: the use of restraints in nursing homes varies among countries and institutions. However, in many countries, no reliable data exist, although restraints use is acknowledged. METHOD: we compare data of the type of restraints used (trunk, limb or chair that prevents rising) and the intensity of its use in eight countries: Denmark, France, Iceland, Italy, Japan, Spain, Sweden and the USA. We report these data in total and for groups of residents with similar functional abilities and cognitive performance, thus avoiding to a certain extent the case-mix differences between samples from different countries. RESULTS: the total use of restraints in these cross-sectional samples showed a very low prevalence in Denmark, Iceland and Japan (less than 9%). Between 15 and 17% were seen in France, Italy, Sweden and the USA, while Spain showed almost 40%. These major differences among the countries persist, even when one controls for physical and cognitive abilities. There are also differences in the types and intensity of restraints used in different countries. In all countries, there is a constant increase in use of restraints with increasing activities of daily living difficulties and cognitive dysfunction.

Using the Resident Assessment Instrument for quality enhancement in nursing homes.

BACKGROUND: in some current policy discussions concerning long-term care, the emphasis has been almost solely on the costs of care. This dialogue must be replaced with a discussion of value, which emphasizes both the costs of care and quality of care. While the Resident Assessment Instrument (RAI) was originally designed as a multidimensional assessment tool aimed at improving clinical practice, it can also provide the foundation for a comprehensive data base that can be used to assess and monitor the quality of care. AIMS and CONCLUSIONS: using data from four sites (in Denmark, Iceland, Italy and the USA) and eight indicators of quality that could be derived from single assessments, we demonstrate how quality might be measured and compared using the RAI. Although this is for illustrative purposes only it does show how this data base can provide invaluable information to providers about the quality of care within their facilities. It can also allow consumers and purchasers to evaluate the relative performance of different providers.

Changes in advance care planning in nursing homes before and after the patient Self-Determination Act: report of a 10-state survey.

OBJECTIVE: The Patient Self-Determination Act (PSDA) implemented in 1991 has focused national attention on the right of patients to be involved in decision-making and on the use of written advance directives. We report changes in advance care planning with the PSDA and other historical events in nursing homes in 10 states. DESIGN: Pre- and Post-observational cohort study. PATIENTS: Nursing home residents, residing in 270 long-term care facilities in 10 states, stratified to ensure representation of urban and rural facilities in each state. In 1990, 2175 patients were sampled, and 2088 different patients from the same facilities were sampled in 1993. Six-month follow-up was obtained at both time periods. MAIN OUTCOME MEASURES: Advance care planning was defined as the documentation in the medical record of a living will, a durable power of attorney, a "Do Not Resuscitate" (DNR) order, a "Do Not Hospitalize" (DNH) order, or an order to forgo artificial nutrition or hospitalization. RESULTS: The rate of chart documentation of living wills increased from 4.2% in 1990 to 13.3% in 1993, and DNR orders increased dramatically from 31.1% to 51.5%. The rates of DNH and orders to forgo artificial hydration and nutrition remained less than 8% in both years. We found striking variations in advance care planing among the 10 states. In 1990, having a DNR order varied from 10.1% to 69.2% across the 10 states. With the exception of Oregon, where 69.2% of patients already had a DNR order, the states saw a 1.5 to 3.1 times increase in the rate of DNR orders in 1993 compared with 1990. CONCLUSION: With the implementation of the PSDA, there was modest increase in documentation of living wills, but DNH and orders to forgo artificial hydration and nutrition remained the same. There was a substantial increase in DNR orders that began before the PSDA implementation. This increase was associated both with the implementation of the PSDA and the increased debate about the appropriateness of CPR for nursing home residents. This increase varied considerably among geographic areas from the 10 states. Future research is needed to understand this geographic variation.

The OBRA-87 nursing home regulations and implementation of the Resident Assessment Instrument: effects on process quality.

OBJECTIVE: To characterize changes in key aspects of process quality received by nursing home residents before and after the implementation of the national nursing home Resident Assessment Instrument (RAI) and other aspects of the Omnibus Budget Reconciliation Act (OBRA) nursing home reforms. DESIGN: A quasi-experimental study using a complex, multistage probability-based sample design, with data collected before (1990) and after (1993) implementation of the RAI and other OBRA provisions. SETTING AND PARTICIPANTS: Two independent cohorts (n > 2000) of residents in a random sample of 254 nursing facilities located in metropolitan statistical areas in 10 states. INTERVENTION: OBRA-87 enhanced the regulation of nursing homes and included new requirements on quality of care, resident assessment, care planning, and the use of neuroleptic drugs and physical restraints. One of the key provisions, used to help implement the OBRA requirements in daily nursing home practice, was the mandatory use of a standardized, comprehensive system, known as the RAI, to assist in assessment and care planning. OBRA provisions went into effect in federal law on October 1, 1990, although delays issuing the regulations led to actual implementation of the RAI during the Spring of 1991. MEASUREMENTS AND ANALYSES: Research nurses spent an average of 4 days per facility in each data collection round, assessing a sample of residents, collecting data through interviews with and observations of residents, interviews with multiple shifts of direct staff caregivers for the sampled residents, and review of medical records, including physician's orders, treatment and care plans, nursing progress notes, and medication records. The RNs collected data on the characteristics of the sampled residents, on the care they received, and on facility practices. The effect of being a member of the 1990 pre-OBRA or the 1993 post-OBRA cohort was assessed on the accuracy of information in the residents' medical records, the comprehensiveness of care plans, and on other key aspects of process quality while controlling for any changes in resident case-mix. The data were analyzed using contingency tables and logistic regression and a special statistical software (SUDAAN) to assure proper variance estimation. RESULTS: Overall, the process of care in nursing homes improved in several important areas. The accuracy of information in residents' medical records increased substantially, as did the comprehensiveness of care plans. In addition, several problematic care practices declined during this period, including use of physical restraints (37.4 to 28.1% (P < .001)) and indwelling urinary catheters (9.8 to 7% (P < .001)). There were also increases in good care practices, such as the presence of advanced directives, participation in activities, and use of toileting programs for residents with bowel incontinence. These results were sustained after controlling for differences in the resident characteristics between 1990 and 1993. Other practices, such as use of antipsychotic drugs, behavior management programs, preventive skin care, and provision of therapies were unaffected, or the differences were not statistically significant, after adjusting for changes in resident case-mix. CONCLUSION: The OBRA reforms and introduction of the RAI constituted an unprecedented implementation of comprehensive geriatric assessment in Medicare- and Medicaid-certified nursing homes. The evaluation of the effects of these interventions demonstrates significant improvements in the quality of care provided to residents. At the same time, these findings suggest that more needs to be done to improve process quality. The results suggest the RAI is one tool that facility staff, therapists, pharmacy consultants, and physicians can use to support their continuing efforts to provide high quality of care and life to the nation's 1.7 million nursing home residents.

Association of the Resident Assessment Instrument (RAI) with changes in function, cognition, and psychosocial status.

OBJECTIVE: To evaluate the impact of the Resident Assessment Instrument (RAI) on changes in nursing home residents' functional status, cognitive status, and psychosocial well-being. DESIGN: A quasi-experiment involving the collection of longitudinal data on two cohorts of nursing home residents. One cohort was assessed before the implementation of the RAI, and the other was assessed after the implementation of the new assessment process. SETTING AND PARTICIPANTS: Over 2000 nursing home residents in 267 nursing homes located in 10 geographic areas were assessed during the pre-RAI period. In the post-RAI period, 2000 new residents in 254 of the same facilities were assessed. INTERVENTION: RAI implementation began in October 1990 and continued until October 1991. The RAI includes a structured, multidimensional resident assessment and problem identification system designed to form the basis for residents' care plans. MEASUREMENTS: All residents were assessed at baseline and at 6 months using the Minimum Data Set for Nursing Home Resident Assessment and Care Screening (MDS) and its protocols. All data were collected by research nurses employed and trained by the research team. RESULTS: Implementation of the RAI significantly reduced the rate of decline in seven of the nine outcomes under consideration. Reductions in improvement were also observed in all outcomes. In activities of daily living, social engagement, and cognitive function, the reduced decline far outweighed any reductions in improvement. In mood problems, problem behaviors, and understanding others, however, reductions in improvement were greater than any reductions in decline. Changes in the rates of decline and improvement were not uniform across all residents. CONCLUSION: The RAI may have improved the quality of care of nursing home residents by reducing overall rates of decline in important areas of resident function. However, this innovation may have generated trade-offs in that it may have reduced improvement rates in some areas of function. The system's implementation also seems to have focused staff's attention on the needs and strengths of specific subpopulations of residents. Revisions of the RAI must assist staff in generalizing their efforts to all residents and to increasing improvement rates, especially in areas related to mood and behavior.

Effect of the National Resident Assessment Instrument on selected health conditions and problems.

OBJECTIVE: To evaluate the effect of the implementation of the National Resident Assessment Instrument (RAI) system on selected conditions representing outcomes for nursing home residents. DESIGN: Quasi-experimental, pre-/post-design, with assessments at baseline and 6-month follow-up. SAMPLE: Two thousand one hundred twenty-eight residents from 268 nursing homes in 10 states before RAI implementation, and 2,088 from 254 of the same nursing homes after implementation. MEASURES: From the full RAI Minimum Data Set, measures of dehydration, falls, decubitus, vision problems, stasis ulcer, pain, dental status (poor teeth), and malnutrition were examined at baseline and 6 months later. Poor nutrition was evaluated using a body mass index score below 20 and vision using a 4-level scale; other conditions were represented by their presence or absence. Decline and improvement were computed as the changes in level between baseline and follow-up, limiting the sample to those who could manifest each such change. MAIN RESULTS: Of eight health conditions representing poorer health status, dehydration and stasis ulcer had significantly lower prevalence after the implementation of the RAI (1993) compared with 1990. At the same time, there was an increase in the prevalence of daily pain. Fewer residents declined over 6 months in nutrition and vision after implementation. Although for these two conditions there were also significantly reduced rates of improvement, the net was an overall reduction in the 6-month rate of decline for all residents. Pain also demonstrated a decline in the postimplementation rate of improvement. The combined eight conditions showed reductions in the rates of both decline and improvement. CONCLUSIONS: Several outcomes for nursing home residents improved after implementation of the RAI. Of the four conditions for which there are significant declines in prevalence or outcome changes, three are specifically addressed in the care planning guidelines incorporated the RAI system (all except stasis ulcer, although there is a RAP for decubitus ulcer). Pain, the only other condition with a significant result --an increase in baseline prevalence--also has no RAP. Although the changes might be ascribed otherwise, they support the premise that the RAI has directly contributed to improved outcomes for nursing home residents.

Sinonasal undifferentiated carcinoma: CT and MR imaging of an uncommon neoplasm of the nasal cavity.

PURPOSE: To determine the computed tomographic (CT) and magnetic resonance (MR) imaging appearance of sinonasal undifferentiated carcinoma. MATERIALS AND METHODS: Findings from 11 patients with histopathologically proved sinonasal undifferentiated carcinoma were retrospectively reviewed. All 11 patients had undergone CT, and six of them had undergone MR imaging. RESULTS: The tumors usually were large (larger than 4 cm in maximum dimension in eight patients), had poorly defined margins, and arose within the ethmoid sinuses and superior nasal cavity. The aggressive nature of the tumor was demonstrated by bone destruction (n = 10) and by invasion of adjacent structures, including paranasal sinuses (n = 10), anterior fossa (n = 7), orbits (n = 4), pterygopalatine fossa (n = 2), parapharyngeal space (n = 1), and cavernous sinus (n = 1). On contrast material-enhanced CT scans, all tumors were enhanced to varying degrees. They tended to be noncalcified (n = 10) and often caused sinus obstruction (n = 10). MR signal intensity of the lesions was isointense to muscle on T1-weighted images in all six patients and iso- to hyperintense on T2-weighted images in five patients. Heterogeneous enhancement of tumors was seen on gadolinium-enhanced images. CONCLUSION: Sinonasal undifferentiated carcinoma cannot be distinguished from other tumors of this region (with the possible exception of melanoma) on the basis of imaging features.

The normal anterior commissure of the glottis.

OBJECTIVE: We characterized the normal width of the anterior commissure of the glottis by measuring its dimensions on CT scans obtained in patients who had no laryngeal disorders. SUBJECTS AND METHODS: CT scans of patients referred for cervical CT myelography were prospectively reviewed by a single board-certified radiologist. Axial images through the anterior commissure (localized by vocal process of the arytenoid cartilage, the vocal muscle, or both) were magnified on the viewing console of the CT scanner. Window and level were chosen to simulate our routine settings for CT scans of the neck. Anteroposterior width of the anterior commissure was measured using an electronic ruler with 1-mm marks. RESULTS: Sixty-five patients were prospectively evaluated. Nine patients were excluded because of substantial motion artifact, and another 18 were excluded because CT images did not include the entire larynx. Thus, the final study group included 38 patients. The average width of the anterior commissure was 1.02 +/- 0.56 mm. The width was less than or equal to 1.1 mm in 22 (58%) of 38 patients. The width was less than or equal to 1.7 mm in 35 (92%) of 38 patients. Forty-two percent (16 of 38 patients) had anterior commissures wider than 1.0 mm. The maximum width of 2.2 mm was seen in only one patient. CONCLUSION: The mean width of the anterior commissure was approximately 1.0 mm. However, 42% of patients had anterior commissures wider than 1.0 mm. In our series, using an upper limit of 1.6 mm as a normal measurement for the anterior commissure would have included 92% of patients, and an upper limit of 2.1 mm would have encompassed the mean plus two SDs.

Accuracy and precision of CT angiography in a model of carotid artery bifurcation stenosis.

PURPOSE: To determine optimal acquisition parameters and measurement techniques for CT angiography of the carotid bifurcation. METHODS: Anatomic phantoms were created in which the diameter of the carotid artery stenoses ranged from 15% to 95%. Initially, we compared the accuracy of stenosis determination obtained by using various values of section collimation and table pitch. Subsequently, applying the combination of collimation and pitch that yielded the greatest longitudinal coverage without degradation in accuracy, we compared the accuracy of measurements performed with various display algorithms, including axial, magnified axial, maximum intensity projection (MIP), and shaded surface display (SSD) images. Last, we determined the effect on accuracy of varying both window and level settings. The standard of reference for all measurements was considered to be caliper measurements made of the models at the time of their construction. RESULTS: CT angiography was highly accurate for determining the percentage of stenosis; the average difference between CT angiographic measurements and the standard of reference was less than 1% for all parameter combinations and measurement techniques. Precision varied among the measurement techniques. Magnified axial images provided more precise measurements than either the MIP or SSD images. Although there was a trend toward improved precision with the use of magnified versus unmagnified axial images and MIP versus SSD images, neither of these comparisons reached statistical significance. Systematic error was produced by changing the level setting from that halfway between the luminal density and vessel wall density. Random error was introduced by using window settings greater than zero. CONCLUSION: CT angiography was highly accurate and precise for determining percentage of stenosis. The highest precision was attained by using magnified axial images with the level halfway between luminal density and vessel wall density and with the window set to zero.

Measurement choices in multi-site studies of outcomes in dementia.

This paper summarizes the measurement choices made by selected current or recently completed multi-site projects with a common emphasis on measuring outcomes in dementia. Information on number of items and scoring, reason(s) for selecting the measure, and reliability and validity of the measure (either citations providing this information or a report of pertinent unpublished findings) is presented for eight domains: cognition, behavioral symptoms, physical health status, physical functioning and self-care abilities, quality of life, family/staff caregiver outcomes, service use, and cost. We found considerable reliance on the published literature as a guide to measurement choice, motivated largely by measures' superior psychometric properties, their ubiquity in the literature, and/or their brevity or ease of use. There is still evidence of "starting from scratch" in some domains, however. To the extent that these projects reflect the state of the art in dementia-relevant outcomes research, we conclude that comparison of outcomes across studies will continue to be problematic. However, as long as dissemination of methodological as well as substantive findings continues to characterize outcome studies in dementia, there is hope that a more congruent view of how to assess key outcomes in dementia will emerge.

The potential for using administrative and clinical data to analyze outcomes for the cognitively impaired: an assessment of the minimum data set for nursing homes.

Quite frequently, data from administrative or clinical data sets are not considered suitable for research because of concerns about their validity and reliability. The authors discuss the important role that such data sets may play in the future of health care. To provide an indication that all administrative and clinical data bases do not provide inferior data, the authors compare the internal consistency and predictive validity of information from three statewide administrative/clinical databases, focusing on nursing home residents with comparable data from a research database. These databases contain information gathered using the Minimum Data Set (MDS) for Nursing Home Resident Assessment and Care Screening. The two dimensions of status considered in this illustration are cognition and physical function. The results of this comparison indicate that the assessment data in three statewide clinical/administrative databases are as reliable and valid as the data found in the research database. Finally, the authors discuss the precepts one might follow in developing clinical/administrative databases that provide good data. These precepts also can be used as guidelines in the evaluation of the probable usefulness of such databases for assessing outcomes among cognitively impaired nursing home residents.

Facility and area variation affecting the use of physical restraints in nursing homes.

OBJECTIVES: Various individual characteristics increase a nursing home resident's likelihood of being mechanically restrained. However, there is not good information on the role played by facility characteristics and geographic area in determining the likelihood of physical restraint use. This study investigates the importance of individual, facility, and area indicators in determining the likelihood of restraint use. METHODS: This research uses data on 2,000 nursing home residents receiving care in more than 250 nursing homes in 10 different areas. Resident-level data were collected in 1990 by research nurses using the Minimum Data Set for Nursing Home Resident Assessment and Care Screening. Facility-level data were gathered by telephone interviews with facility staff. The relations among the variables were investigated using contingency tables and multivariate logistic regression models. RESULTS: Controlling for residents' physical and cognitive function, facility characteristics and location had a significant impact on restraint practices. Those facilities with low nurse staffing were more likely to restrain residents. Furthermore, controlling for these factors, restraint practices varied significantly across the geographic areas in the study. CONCLUSIONS: Like hospitals, nursing homes exhibit significant interfacility and regional variation in their clinical practices. Future analyses of nursing home care might benefit from considering both factors in much finer detail.

Measuring program performance in methadone treatment using in-treatment outcomes: an illustration.

Quality measurement and quality assurance in substance abuse treatment have, over the past few years, become a major policy issue. In addition, there is interest in the degree to which client outcomes can play a role in measuring treatment program performance. This article discusses the movement toward outcome-based performance measurement in substance abuse treatment. Examples of the products that such a performance measurement system might produce are provided. Why outcomes must be case-mix adjusted is discussed. In addition, using data from 18 methadone programs and more than 2,000 methadone clients from the Treatment Outcome Prospective Study, an illustration of case-mix-adjusted performance measurement is provided.

Validation of the Minimum Data Set Cognitive Performance Scale: agreement with the Mini-Mental State Examination.

BACKGROUND: Almost all nursing homes in the United States are required by the 1987 Omnibus Budget Reconciliation Act to assess each resident's functional, medical, psychosocial, and cognitive status using a standard instrument known as the Minimum Data Set (MDS). We report a validation study to show that the MDS Cognitive Performance Scale (CPS), a cognitive measure generated from 5 MDS items (comatose status, decision making, short-term memory, making self understood, and eating) can be used to detect cognitive impairment as defined by the Mini-Mental State Examination (MMSE). METHODS: Two hundred subjects were randomly recruited from 8 nursing home facilities in North Carolina. Two medical students administered the MMSE, while a geriatric research nurse was responsible for collecting MDS cognitive items, which included the 5 items required for generating CPS scores. Cognitive impairment was defined by MMSE scores adjusted for education. Agreement between the CPS and the MMSE in identifying cognitively impaired subjects was then evaluated. RESULTS: The CPS showed substantial agreement with the MMSE in the identification of cognitive impairment; the sensitivity was .94 (95% confidence interval [CI]: .90, .98), the specificity was .94 (95% CI: .87, .96), and the diagnostic accuracy as measured by the area under the receiver operating characteristics (ROC) curve was .96 (95% CI: .88, 1.0). CONCLUSIONS: The MDS Cognitive Performance Scale, when performed by a trained research nurse using recommended protocols, provides a valid measure of cognitive status in nursing home residents.

Reliability estimates for the Minimum Data Set for nursing home resident assessment and care screening (MDS).

The MDS is a core set of items, definitions, and response categories used to assess all of the nation's 1.5 million nursing home residents who reside in facilities participating in the Medicare or Medicaid programs. Further, the Health Care Financing Administration (HCFA) has proposed a rule that would require facilities to computerize MDS data and submit it to state and federal agencies, paving the way for a national database. This article describes the process of testing the reliability of the MDS items in 13 nursing homes in five states. The results demonstrate that MDS data gathered in a research effort attain reliabilities that make such data useful. MDS items met a standard for excellent reliability (i.e., intraclass correlation of .7 or higher) in key areas of functional status, such as cognition, ADLs, continence, and diagnoses. Sixty-three percent of the items achieved reliability coefficients of .6 or higher. Eighty-nine percent of the items in the MDS achieved .4 or higher.
