Effect of pressure ulcers on the survival of long-term care residents

BACKGROUND: Past studies have emphasized that patients with pressure ulcers are at high risk of dying. However, it remains unclear whether this increased risk is related to the ulcer or to coexisting conditions. In this study we examined the independent effect of pressure ulcers on the survival of long-term care residents. METHODS: We evaluated all 19,981 long-term care residents institutionalized in Department of Veterans Affairs (VA) long-term care facilities as of April 1, 1993. Baseline resident characteristics and survival status were obtained by merging data from five existing VA data bases. Survival experience over a 6-month period was described using a proportional hazards model. RESULTS: Pressure ulcers were present in 1,539 (7.7%) long-term care residents. Residents with pressure ulcers had a relative risk of 2.37 (95% CI = 2.13, 2.64) for dying as compared to those without ulcers. After adjusting for 16 other measures of clinical and functional status, the relative risk associated with pressure ulcers decreased to 1.45 (95% CI = 1.30, 1.65). No increased risk of death was noted for residents with deeper ulcers. CONCLUSIONS: Pressure ulcers are a significant marker for long-term care residents at risk of dying. After adjusting for clinical and functional status, however, the independent risk associated with pressure ulcers declines considerably. The fact that larger ulcers are not associated with greater risk suggests that other unmeasured clinical conditions may also be contributing to the increased mortality associated with pressure ulcers.     

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.     

Nurse staffing and quality of care in nursing facilities

A study of 198 nursing facilities in Maryland tested the hypotheses that: 1) the presence of more RNs improves the quality of nursing care; and 2) increased numbers of all types of nursing staff improve the quality of nursing care, based on a multidimensional measure of quality of nursing care. Findings indicate that the ratio of RNs to residents is directly related to a measure of resident rights deficiencies. In addition, the ratio of total nursing staff to residents is directly related to a lower overall deficiency index and a higher quality of care score.     

MDS+ RAP items associated with pressure ulcer prevalence in newly institutionalized elderly: study I

All federally funded facilities are required to use the Minimum Data Set Plus (MDS+) for functional assessment of their residents. Within the MDS+ there are 18 specific conditions addressed through Resident Assessment Protocols (RAPs). There is a RAP for pressure ulcers but the validity of the pressure ulcer RAP items has not been documented. The purpose of this study was to determine which pressure ulcer RAP items correlate with pressure ulcer prevalence in newly institutionalized elderly and whether inclusion of nutritional status information to the correlated RAP items increases association with pressure ulcer prevalence. Data were collected through a retrospective chart review of 990 residents over age 65 at 8 nursing homes. Five pressure ulcer RAP items were predictive of pressure ulcer prevalence 19.76% of the time. When nutritional status markers were added in a logistic regression, pressure ulcers were correctly predicted 32.3% of the time. In clinical practice, the pressure ulcer RAP needs to include nutritional status information to accurately reflect pressure ulcer risk.     

Use of Veterans Affairs Health Care Services by Veterans Receiving Addiction Treatment in Washington State.

The authors describe characteristics of treatment use among veterans who had addiction treatment in non-Veterans Affairs (VA) facilities in Washington state and who used health care services, including addiction treatment, in VA facilities. From 1996 through 2000, 2,649 VA patients received addiction treatment in Washington state facilities, with 56% (n = 1,489) also receiving some VA specialty addiction treatment and the remaining 44% (n = 1,160) receiving VA health care services unrelated to addiction treatment. Among all veterans receiving addiction treatment in VA facilities in Washington state (n = 11,663), 11% also had treatment in non-VA centers. Over the more than 4-year period, female veterans seen in both systems were less likely to receive VA specialty addiction treatment than were male veterans (40% vs. 58%). This article shows that a significant number of veterans received addiction treatment in both VA and non-VA facilities in Washington state.

Inpatient hospital utilization among veterans with traumatic spinal cord injury

OBJECTIVE: To describe the pattern of inpatient hospital utilization, up to 15 years after injury, among a cohort of veterans with service-connected traumatic spinal cord injury (SCI). PATIENTS: A cohort of 1,250 male veterans, with traumatic SCI occurring between 1970 and 1986, who visited the VA within 1 year of injury, was assembled from VA administrative files; diagnosis was verified by examining hospital discharge summaries. DESIGN: Computerized record linkage among Department of Veterans Affairs (VA) administrative files was used to determine patterns of inpatient hospital utilization. MAIN OUTCOME MEASURE: Pattern of inpatient admissions and length of stay (LOS). RESULTS: Patients were typically white males injured in their mid-twenties. The initial VA hospitalization began approximately 6 weeks after injury and lasted 4 to 7 months, depending on injury level and completeness. Subsequent hospitalizations usually lasted approximately 10 days, but 22% of stays exceeded 1 months. Most hospitalizations took place in specialized SCI Centers. Comparing the 1980s with the 1970s, patients in the 1980s entered VA facilities sooner after injury, were more likely to visit SCI Centers, and had shorter initial stays. Rates for the incidence of rehospitalization decreased rapidly in years 2-5 after injury and declined less rapidly thereafter. Occupancy rates and proportion rehospitalized followed similar patterns. The incidence rate for persons with complete quadriplegia was approximately twice that of patients with incomplete paraplegia. Between 1970 and 1991, both the rehospitalization incidence rate and LOS decreased by approximately 20%. Only 10% of patients accounted for 46% of the total LOS. LOS during the first five years was predictive of later LOS. CONCLUSIONS: The pattern of rehospitalization in VA facilities was generally consistent with that of the Model Systems. Efforts toward preventing rehospitalization should target persons with previous high utilization.     

Primary care within the VA: the firm model

Many of the VA medical centers are reorganizing total care across a continuum that includes outpatient, inpatient, long-term, and home based care, into interdisciplinary firms. The goals of reorganization are to improve patient access to care and continuity of care, to improve housestaff education by assigning a specific panel of patients for the residents to follow longitudinally in a variety of situations supervised by the same mentors, and to enhance research in primary care issues. Preliminary results show increased patient satisfaction and improvements in both quality of care and increased efficiency in its delivery. Many large health care organizations might be expected to reorganize care delivery around a similar interdisciplinary team concept.     

Psychotherapy in long-term care: II. Evidence-based psychological treatments and other outcome research.

This article is the 2nd of 2 that together examine 3 domains important to providing high-quality, evidence-based services to long-term care (LTC) facility residents: policy and advocacy, practical considerations, and outcome research. Older adults who reside in LTC facilities have a very high rate of mental health difficulties. Psychologists have been able to provide services to this population through Medicare since the late 1980s, and empirical findings on treatment approaches are important in guiding psychotherapists to more helpful intervention. The focus of this article is outcome research in LTC settings. This article emphasizes evidence-based psychological treatments (EBTs) but also examines other scientifically supported approaches and discusses the strengths and limitations of focusing on EBTs, as well as general issues in the relation between science and practice in the provision of psychotherapy in LTC settings.

Private health insurance and veterans use of Veterans Affairs care. RATE Project Committee. Rate Alternative Technical Evaluation

OBJECTIVES: This study examined the effect of private health insurance on the use of medical, surgical, psychiatric, and addiction services for patients eligible for publicly supported care. METHODS: The authors assembled administrative databases describing 350,000 noninstitutionalized veterans who had been discharged from a Veterans Affairs (VA) inpatient medicine or surgery bed section during a 1-year period. Patient use of care was followed for 1 year after the index discharge. Patient insurance information came from Medical Care Cost Recovery Billing and Collection files obtained separately from each of 162 VA Medical Centers. Distances between VA and non-VA sources of care were estimated from the Health Care Financing Administration's Hospital Distance File. RESULTS: Insured patients were less likely to seek surgical care but were 12 times (65 years of age and older) and 73 times (63 years of age and younger) more likely to initiate outpatient medical visits than were their counterparts, adjusted for patient demographic, diagnostic, and index facility characteristics. Patients who had private health insurance also were 3.4 (> or = 65) and 2.6 (< or = 64) times less likely to use VA surgical care in response to changes in available surgical staff-to-patient ratios than were their uninsured counterparts. CONCLUSIONS: Private health insurance may substitute (reduce) or complement (increase) the continued use of publicly supported health care services, depending on patient age, care setting, and service type.     

Automating and improving the data quality of a nursing department quality management program at a university hospital

BACKGROUND: The development and implementation of a relational database program for nursing quality management at a university hospital was stimulated by a lack of consistent data management and analysis tools in the existing noncomputerized program. PROGRAM DEVELOPMENT AND IMPLEMENTATION: An initial software prototype implemented in the critical care service included data collection instruments for five areas: medication errors, patient falls, returns to an intensive care unit within 48 hours, hospital-acquired skin breakdown, and unplanned extubations. Access to the database was limited and paper reports only were disseminated on a scheduled basis. In a second phase, the database is being deployed throughout the nursing department using a local area network. Nurse managers will enter and interact with the quality database online and have access to graphics, reports, and action plan development. POSSIBLE ERRORS: A wide range of potential errors influences decisions on how to collect, store, retrieve, and process quality management data. Each type of error affects the nurse manager's ability to identify significant patterns or trends that are amenable to intervention. There is no right way of constructing and implementing a quality improvement database; only an optimum balance between cost, complexity, and efficacy. SUMMARY AND CONCLUSIONS: Initial feedback from end uses has been positive. A three-year experience with a personal computer database suggests that the personal computer-based information technology is appropriate for small to medium applications and can support departmentwide CQI efforts. A case scenario using simulated data is included to illustrate the use of computerized reports in assessing and taking action on an increase in falls.     

An empirical test of the structure, process, and outcome quality paradigm using resident-based, nursing facility assessment data

This study distinguishes between organizational characteristics, regarded as exogenous structural indicators of quality, and those identified as endogenous indicators of structural care (SC), and investigates the degree to which measures of SC vary by ownership mode (defined by four combinations of chain affiliation and profit status) for 142 certified and licensed nursing facilities (NFs) in a southern state. Structural care measures include: licensed and unlicensed staffing, licensed therapists, and case mix-adjusted direct care expenditures. In addition, seven (four process and three outcome) facility-level, risk-adjusted process, and outcome quality scales are developed from 39 resident-level quality indicators. A causal mode of NF quality arranged according to the structure, process and outcome paradigm is specified and estimated using path analysis. Organizational data derive from the 1991 Medicaid Cost Report; process and outcome quality measures were developed from the Minimum Data Set Plus Resident Assessment Instrument. Using the percentage of Medicaid and private pay residents as covariates, there was a significant overall multivariate effect due to ownership mode on the SC measures. Although there were several significant direct effects, the overall path model was unconfirmed. The multivariate results suggest that some organizational characteristics of structure quality may be more appropriately considered exogenous to causal quality models and therefore have indirect (versus direct) effects on process or outcome quality indicators. The path analysis implies that the structure-process-outcome paradigm may not accurately capture the way NF health care is delivered. Research which considers alternate NF quality paradigms needs to be done with samples that are more representative of national proportions of each ownership mode.     

Applying case mix adjustment in profiling primary care physician performance

This project was conducted with two objectives: developing a simple and meaningful performance efficiency index for profiling primary care physician (PCP) practice patterns and testing the explanatory power of the ambulatory care group case mix system in controlling for variation in patients' resource needs. The findings indicate that large administrative databases can provide valuable information for health services management. However, effort should be made to focus on methodological issues in analyzing those data sources. Conventional demographic risk adjustment factors (age and sex) are not adequate. Greater priority needs to be given to developing and applying additional risk adjustment systems to maximize the value of large administrative databases in profiling the relative efficiency of PCPs.     

Chemotherapeutics for treatment of influenza and other viral respiratory tract infections in children

Regardless of the primary care model used in the long-term care facility, each of the three approaches offers quality care improvement and greater consistency for residents at reduced costs. Of the three, an all licensed nursing staff model could best meet the higher acuity levels of residents and the disintegrating availability of qualified nursing assistants. If nurses are unable to "sell" this model to administration, it may be helpful to pilot the concept one one unit for a period of time and compare resident, family, and staff satisfaction with that of a similar unit. Also, it is critical to compare the financial implications, including cost per resident per day and rate of staff turnover, to weigh the model's effectiveness. This small sampling of five facilities indicates the average cost per resident per day is $10 less when using either the primary team or all licensed staff models than in facilities of comparable size. Hospitals have already passed the time when they have had to work smarter, leaner, and more efficiently. Can long-term care facilities afford not to do the same?     

Assessing influenza immunization rates in Medicare managed care plans: a comparison of three methods

BACKGROUND: In an effort to improve care delivered to Medicare beneficiaries, the Health Care Financing Administration (HCFA) has encouraged competitive Medicare risk plans to collaborate on quality improvement projects. PRO-West, a private, nonprofit quality improvement organization, fostered a collaboration of all Medicare risk plans in Washington State in order to assess and improve influenza immunization rates among seniors enrolled in managed care. METHODOLOGY: After the 1994-1995 influenza immunization season, immunization rates were determined for each participating plan from administrative data and medical record review. In the 1995-1996 season, these methods were supplemented with a telephone survey. The survey was used to identify perceived barriers to immunization and to estimate immunization rates. RESULTS: Immunization rates, as estimated by administrative data and medical record review, were similar for both years. The average immunization rate using administrative data for the 1995-1996 flu season was 60.6% (range, 42.8% to 72.3%). The estimated rate increased to 77.8% (95% confidence interval, 75.3% to 80.3%) when the telephone survey data were added. Medical record review contributed little additional information. CONCLUSIONS: Influenza immunization rates for seniors enrolled in Medicare risk plans in Washington State exceed those reported for fee-for-service Medicare beneficiaries. Telephone surveys resulted in higher and probably more valid estimates of influenza immunization rates than did analysis of administrative data and medical records. Plans with lower rates can emulate "benchmark" plans that are explicit about the methods they use to achieve high coverage rates. Medicare risk health plans competing in the same markets can collaborate in quality assessment activities in an effective manner.     

Position changes for residents in long-term care

The purpose of this study in long-term care facilities was to determine the factors associated with the common pressure ulcer prevention practice of turning and positioning of residents. The study showed there was a deficit in performance of two-hour turning, but not in knowledge that turning should be done. The chief reason for the aides' performance deficit was a lack of specific assignment to the task as well as a lack of time and staff. Head nurses and directors of nursing acknowledged these problems and also cited copious paperwork that prevented them from spending the necessary time to monitor compliance to facility policies on turning and positioning.     

HOMSTRAD: a database of protein structure alignments for homologous families

We describe a database of protein structure alignments for homologous families. The database HOMSTRAD presently contains 130 protein families and 590 aligned structures, which have been selected on the basis of quality of the X-ray analysis and accuracy of the structure. For each family, the database provides a structure-based alignment derived using COMPARER and annotated with JOY in a special format that represents the local structural environment of each amino acid residue. HOMSTRAD also provides a set of superposed atomic coordinates obtained using MNYFIT, which can be viewed with a graphical user interface or used for comparative modeling studies. The database is freely available on the World Wide Web at: http://www-cryst.bioc.cam. ac.uk/-homstrad/, with search facilities and links to other databases.     

Socioeconomic differences in 'avoidable' mortality in Sweden 1986-1990

BACKGROUND: 'Avoidable' mortality is commonly studied as an indicator of the outcome of health care. In this study socioeconomic differences in avoidable mortality in Sweden from 1986 to 1990 are analysed and related methodological issues discussed. METHODS: The 1985 Swedish Population and Housing Census was linked to the National Cause of Death Register 1986-1990. Mortality from potentially 'avoidable' causes of death was analysed for the age group 21-64 years. Analyses were performed for different socioeconomic groups, blue-collar workers, white-collar workers and the self-employed as well as for individuals outside the labour market. Standardized Mortality Ratios were calculated using standardization by age and sex. RESULTS: For all indicators studied, the death rates for those not in work were higher than for people at work. The largest differences were found for chronic bronchitis, diabetes, bacterial meningitis, ulcer of the stomach and duodenum, chronic rheumatic heart disease, asthma and hypertensive and cerebrovascular disease. For these causes of death the risk of dying was between 3.1 and 7.5 times greater in the non-working population than in the work-force. The differences in avoidable mortality between blue-collar workers and white-collar workers and the self-employed were, however, much smaller. For most of the indicators no significant differences were found. For ulcers of the stomach and duodenum, however the death rate for blue-collar workers was 2.8 times higher than those for other categories in work. CONCLUSIONS: The small difference in mortality outcome for different socioeconomic groups within the work-force indicates an equal quality of care for these groups. The greatly increased risk among the non-working population, however, is a warning sign. These results may be due to a 'healthy worker' effect. The measurement of socioeconomic differences in mortality may be dependent on the time-period chosen between occupational exposure and mortality outcome.     

Urinary incontinence in patients in long-term institutional care. Results of an international study in 8 countries

BACKGROUND: Urinary incontinence (UI) represents a prevalent nursing problem in geriatric facilities. Yet, comparison of the Czech Republic with countries using different chronic care system has not been conducted. METHODS AND RESULTS: Data from INTERRAI international database from 8 countries: Czech Republic, Denmark, France, Iceland, Italy, Japan, Sweden and USA have been evaluated in the sample of 280,271 nursing home residents. Prevalence of bladder and bowel incontinence and correlates with selected clinical factors have been determined and national samples compared with the results of 1080 patients in the Czech Republic. Prevalence of UI reached from 42.9% in Japan to 65.2% in France. France and CR belong to countries with the highest prevalence of both bladder and bowel incontinence. Cognitive impairment and dependency in ambulation are factors significantly associated with UI in all countries (p < 0.001). Immobility, age, gender and urinary tract infection reached the statistical significance only in some countries. CONCLUSIONS: High prevalence of bladder and bowel incontinence has been demonstrated in an extended sample of nursing home residents. Common protocol Resident Assessment Instrument-Minimum Data Set (RAI-MDS) and creation of a large cross-national database are opening up possibilities for a new level of clinical research in geriatrics.     

Admission to hospitals with on-site cardiac catheterization facilities :impact on long-term costs and outcomes

BACKGROUND: Admission to a hospital with a capability for cardiac procedures is associated with a higher likelihood of referral for a cardiac procedure but not with a better short-term clinical outcome. Whether there are differences in long-term mortality and resource consumption is not clear. We sought to determine whether elderly Medicare patients with acute myocardial infarction admitted to hospitals with on-site cardiac catheterization facilities have lower long-term hospital costs and better outcomes than patients admitted to hospitals without such facilities. METHODS AND RESULTS: As part of the Cooperative Cardiovascular Project pilot in Connecticut, we conducted a retrospective cohort study using data from medical charts and administrative files. The study sample included 2521 patients with acute myocardial infarction covered by Medicare from 1992 to 1993. The cardiac catheterization rate was higher in the hospitals with facilities (38.6% versus 26.9%; P<0.001), but the revascularization rate was similar (20.5% versus 19.5%) during the initial episode of care and at 3 years (29.7% versus 29.7%). Mortality rates were similar for patients admitted to the 2 types of hospitals at 30 days (OR, 1.08; 95% CI, 0.83 to 1.42) and at 3 years (OR, 1.02; 95% CI, 0.83 to 1.26). The adjusted readmission rates were significantly lower among patients admitted to hospitals with cardiac catheterization facilities (OR, 0.76; 95% CI, 0.61 to 0.94). However, the overall mean days in the hospital for the 3 years after admission was 25.9 for patients admitted to hospitals with facilities and 24.6 for the other patients (P=0.234). Adjusting for baseline patient characteristics, there was no significant difference in the 3-year costs between patients admitted to the 2 types of hospitals. CONCLUSIONS: With higher rates of cardiac catheterization and lower readmission rates, patients admitted to hospitals with on-site cardiac catheterization facilities did not have significantly different hospital costs compared with patients admitted to hospitals without these facilities. There was also no significant difference in short- or long-term mortality rates.
