Reliability and validity of a modified Colorado Symptom Index in a national homeless sample.

This study examined the reliability and construct validity of a modified version of the Colorado Symptom Index (MCSI), a brief, self-report measure of psychological symptomatology, in a study of interventions to prevent homelessness. Eight projects in a national, cooperative study collected new data at baseline, 6, and 12 months using a set of common measures as well as site-specific instruments. The pooled sample consisted of 1,381 persons in treatment for mental illness or substance abuse (or both), of which 84% had a history of homelessness. The analyses employed classical and Rasch methods to examine the MCSI's content validity, internal consistency and item quality, test/retest reliability, dimensionality, appropriateness for the sample, construct validity, and responsiveness to change. This 14-item scale was found to be a reliable and valid measure of psychological symptoms in this sample. Its content was consistent with other symptom measures, its high internal consistency and test-retest coefficients supported its reliability, its relationships to other measures indicated that it had good construct validity, and it was responsive to change. We conclude that the MC

An agency-based representative payee program and improved community tenure of persons with mental illness.

OBJECTIVE: Representative payee programs help severely mentally ill individuals manage money from their Social Security payments to cover expenses for necessities and to avoid homelessness and rehospitalization. This study examined a representative payee program operated by a community mental health center to determine the criteria used by clinicians and ease managers to refer clients to the program and to learn whether participation in the program was associated with reductions in hospitalization. METHODS: The retrospective study included 56 individuals with severe mental illness who were enrolled in the representative payee program at Community Counseling Centers of Chicago for one year and who also had received services from the agency for at least one year before enrollment. Criteria used to refer clients to the representative payee program were determined through chart reviews. Data on state hospitalizations before and after enrollment were available for the entire sample; additional data on Medicaid-funded private hospitalizations were available for a subset of 33 clients. RESULTS: The most common criteria for enrollment in the representative payee program were comorbid substance abuse or dependence (49 percent), a history of homelessness (33 percent), and frequent hospitalizations (32 percent). During the year of participation in the representative payee program, the mean number of days spent in state hospitals decreased markedly compared with the year before enrollment, from 68 days to seven days. A similar reduction was noted in the number of days spent in state and private hospitals, from 97 days to 15 days. CONCLUSIONS: Findings from this pre- and postintervention retrospective study are tentative in the absence of a more rigorous design. However, the results suggest that the representative payee program is quite effective in reducing hospital stays.

Characteristics of persons with mental illness in a representative payee program.

This study compared the characteristics of 56 clients with severe mental illness in a community mental health agency's representative payeeship program with those of 54 clients who did not participate in the program. Based on data from a two-year period, participants in the representative payee program were characterized by disability or financial distress, indicated by a diagnosis of schizophrenia, homelessness, lack of rent money, and lack of financial skills; long-term dependence on income from Social Security and services provided by the mental health system, evidenced by receipt of Supplemental Security Income and frequent hospitalizations; and lack of financial independence, as reflected by inability to earn income from employment and lack of financial support from family.

Prevalence of subacute patients in acute care: results of a study of VA hospitals.

Subacute care is a transitional level of care for medically stable patients who no longer require daily diagnostic/invasive care but require more intensive care than is typical in a skilled care facility. A Congressionally mandated study was undertaken to determine the number of VA patients with subacute needs being cared for in acute care. InterQual, Inc. subacute care criteria were retrospectively applied to 858 medical and surgical admissions from 43 VA hospitals. Over one-third contained at least one subacute day; with an average length of stay (LOS) of 12.7 days (SD = 12.4); of which 6.8 days were subacute. Patients with these admissions had significantly longer LOSs, were older, and were more likely to die or to be discharged to a nursing home. Diagnoses with subacute days included COPD, pneumonia, joint replacement, and cellulitis. Future studies should develop clinical pathways to prospectively manage admissions with subacute needs and then evaluate their effectiveness.

Case managed residential care for homeless addicted veterans. Results of a true experiment.

OBJECTIVES: The effectiveness of case-managed residential care (CMRC) in reducing substance abuse, increasing employment, decreasing homelessness, and improving health was examined. METHODS: A five-year prospective experiment included 358 homeless addicted male veterans 3, 6, and 9 months during their enrollment and at 12, 18, and 24 months after the completion of the experimental case-managed residential care program. The customary control condition was a 21-day hospital program with referral to community services. RESULTS: The experimental group averaged 3.4 months in transitional residential care with ongoing and follow-up case management for a total of up to 1 year of treatment. The experimental group showed significant improvement compared with the control group on the Medical, Alcohol, Employment, and Housing measures during the 2-year period. An examination of the time trends indicated that these group differences tended to occur during the treatment year, however, and to diminish during the follow-up year. CONCLUSIONS: Within groups, significant improvements were observed with time from baseline to all posttests on the four major outcomes. We learned, however, that veterans had access to and used significant amounts of services even without the special case-managed residential care program. This partially may account for improvements in the control group and may have muted the differences between groups.

Evaluation of a prospective payment system for VA contract nursing homes.

An evaluation of a pilot program for community nursing home care reimbursement by Department of Veterans Affairs Medical Centers (VAMCs) was undertaken. Eight VAMCs began using the Enhanced Prospective Payment System (EPPS) in 1992. These sites were compared to eight customary payment sites in a pretest/posttest quasi-experimental design. Outcomes included access to care, administrative workload, quality of care, and cost. As expected, per diem costs were significantly higher for EPPS than customary reimbursement patients ($106 vs. $87). However, EPPS sites placed veterans more quickly (81 days vs. 113 days; p < .01) than comparison sites and reduced administrative workload associated with placement. EPPS sites also increased the number of Medicare-certified homes under contract (76% vs. 54%) and placed significantly more veterans who received therapy (20% vs. < 1%). Savings in hospital days more than offset the increased cost of nursing home placement. Because the findings were attributed largely to a few veterans with long lengths of hospital stay, the early success of EPPS may diminish as the backlog of these long-stay patients decreases.

Gene therapy of cancer.

OBJECTIVE: To provide a review of the basic concepts and terminology of human genetics, the clinical application and risks of gene therapy, and ethical and societal issues. DATA SOURCES: Review articles, research studies, and book chapters related to genetics and human gene therapy. CONCLUSIONS: The genetic changes that play a role in the development of cancer have begun to be elucidated, and these discoveries have led to strategies to destroy cancers by correcting genetic defects or manipulating genes to induce tumoricidal activities. Gene therapy is a novel investigational intervention that is constantly evolving. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses will need an increased understanding of cellular biology, genetics, and genetics engineering. Major considerations for nursing practice include patient and family education, informed consent, side effects, and ethical and societal issues.

Impacts of foot orthoses on pain and disability in rheumatoid arthritics.

Rheumatoid arthritis (RA) frequently causes foot pain and swelling that affect ambulation. Pharmaceutical management of pain and disability is standard in clinical practice. The use of functional posted foot orthoses, as an adjunct to pharmaceutical treatment, is a promising treatment for managing foot pain and disability in RA. Its effectiveness, however, has not been rigorously evaluated. We performed a double-blind clinical trial using foot orthoses vs. placebo orthoses in the management of the rheumatoid arthritic foot, while subjects continued customary treatment. On the basis of findings of no effect on disability and pain measures, this study indicates no benefit of functional posted foot orthoses over placebos.

Can foot orthoses prevent hallux valgus deformity in rheumatoid arthritis? A randomized clinical trial.

Hallux valgus deformity is the most commonly observed forefoot deformity in patients with rheumatoid arthritis. This 5-year, double-blind, randomized clinical trial compared treatment orthoses with placebo orthoses for the prevention of hallux valgus deformity in the rheumatoid arthritic foot.One hundred and two subjects with active rheumatoid arthritis and with foot pain and minimal radiographic changes of the feet participated in the study. They were recruited from five arthritis clinics in the Chicago metropolitan area that are affiliated with or are teaching clinics of area medical schools. Patients were followed for 3 years.Eighty-one subjects completed the study. In a logistic regression analysis, the treatment group was 73% less likely to develop hallux valgus deformity compared with the control group (adjusted odds ratio 0.27, 95% confidence interval 0.078, 0.916 p = .04). These findings suggest that foot orthoses can prevent or slow the progression of hallux valgus deformity.

Patient education resources related to biotherapy and the immune system.

PURPOSE/OBJECTIVES: To provide cancer care professionals with insight into available patient education resources related to biotherapy. DATA SOURCES: Literature from pharmaceutical companies, national organizations, the National Cancer Institute, and individual cancer centers. DATA SYNTHESIS: Comprehensive, but not all-inclusive, list of booklets, videotapes, and fact sheets currently available to inform and instruct patients and families regarding biotherapy, injection techniques, the immune system, and reimbursement strategies. CONCLUSIONS: Using available materials eliminates the need to develop new products and standardizes patient instruction. IMPLICATIONS FOR NURSING PRACTICE: These products facilitate patient and family education to promote understanding of the disease and treatment plan. Increased understanding can lead to independence and confidence in self-care.

Radiographic measurement of hallux valgus in the rheumatoid arthritic foot.

OBJECTIVE: To develop a method which is objective and quantifiable, as well as reliable and valid for measuring the severity and progression of hallux valgus deformity (HVD). HVD is defined as an increase in the hallux abductus angle (HAA). METHODS: HAA drawn on plain anterioposterior radiographs of the foot was measured in 94 patients with rheumatoid arthritis. The intra and interrater reliability were analyzed. RESULTS: Findings were significant with interclass correlation coefficients ranging from 0.9 to 0.99. Detection of changes in HAA using this method were comparable to the judgment of a panel of experienced clinicians. CONCLUSION: This method is useful in detecting progression of HVD.

Adult day health care organizational and program characteristics.

A survey of 31 adult day health care (ADHC) programs assessed the extent to which the programs were implemented as intended by the VA. The study described and compared the host communities, ADHC organizational characteristics, program characteristics, and patient use of services. Four of the centers were operated by the Department of Veterans Affairs in VA Medical Center facilities. The remaining 27 centers were community providers serving veterans on contract through four additional VA Medical Centers. Veterans Administration programs were located in larger facilities, with lower client/staff ratios and fewer hours of operation than community contract programs. Patients on the average made 45 visits to the VA-ADHC programs and 58 visits to the contract ADHC programs. The VA and contract programs were generally found to have been implemented as planned, i.e., they followed VA guidelines for staffing, space, and equipment.

A short-term, three-year epidemiological study of median nerve sensitivity in practicing dental hygienists.

PURPOSE: Hand-intensive, repetitive motion procedures such as those performed by dental hygienists can lead to median nerve dysfunction which, left untreated, can degenerate into clinical carpal tunnel syndrome (CTS). Vibrometry has been used as a method for early detection of sensory nerve impairment. METHODS: A cohort of 16 university-educated dental hygienists was evaluated by means of programmed frequency stimuli for median nerve dysfunction at graduation and at one, two, and three years postgraduation. RESULTS: The results indicate that median nerve dysfunction was not detected in this cohort. However, further analysis suggests that a significant loss of median nerve sensitivity, or permanent "threshold shift," has occurred in the three years since graduation. CONCLUSION: Whether this is a harbinger of future events is unknown at this time.

Classification of adult day care: a cluster analysis of services and activities.

Using data from a 1986 national census survey of 774 adult day care (ADC) centers, this study (a) determined whether distinct classes of ADC could be identified based on measures of program services and activities, and (b) delineated the distinguishing characteristics of such classes on other available measures of structure, process, and client population. A cluster analysis of 10 "process" measures of services and activities identified 6 classes of ADC centers: Alzheimer's Family Care, Rehabilitation, High Intensity Clinical/Social, Moderate Intensity Clinical/Social, General Purpose, and Low Scoring. Validity was examined by developing a set of expectations for pairs of classes on other available variables. Of 12 expectations, 11 were supported by the statistical tests. Finally, profiles of the 6 classes were developed to describe the classes on 30 other characteristics. The findings clarify the settings to which previous ADC studies are generalizable and indicate a need for effectiveness studies on special classes of ADC.

A medicare adult day care model: proposed criteria and available supply.

The study on which this article is based addressed the issue of the proportion of adult day care centers (ADCs) existing in 1986 that would qualify for Medicare funding under the 1989 U.S. Senate Medicare Adult Day Care Amendments. It also estimated the impact of the criteria on two policy-relevant subgroups of ADCs-that is, Alzheimer's vs. non-Alzheimer's and rural vs. urban-using data from a 1986 national census survey of ADCs. The five proposed Medicare criteria and the percentage of ADCs meeting them were: services to be provided directly, 14.6%; multi-disciplinary team, 20%; services to be provided directly or indirectly, 16%; program activities, 42%; and other, 53%. Only 3% met all five criteria while 13% met four out of five. Alzheimer's centers met the criteria more often than non-Alzheimer's centers, while urban centers qualified more often than rural centers. Based on the findings, implications for Medicare funding policy are discussed.

Program factors that influence utilization of adult day care.

Health planners, policymakers, and providers urgently require methods and information that explain the factors that affect health services utilization. This information is especially critical for planning programs that are effective in maintaining the burgeoning elderly population in community care. In this study, correlation and regression analyses examined the characteristics of adult day care (ADC) centers that were associated with utilization as operationalized by demand for and actual attendance in 822 centers. Community, client population, services and activities, and structural characteristics were associated with demand per center whereas the social environment of the ADC center was not. The attendance rate was most strongly affected by services and activities and structural characteristics. The significance of the study, its limitations, and future directions for research are discussed.

Assessing the influence of adult day care on client satisfaction.

Using data collected from 74 adult day care centers, this study measured various program characteristics from four different categories of respondents--clients, caregivers, staff members, and administrators. The perceptions of these respondents were examined for their associations with each other and with client satisfaction. Three program characteristics, as perceived by clients, were significantly associated with client satisfaction (staff caring, general morale, and interior environment). The caregivers', staff members' and administrators' perceptions were not significantly associated with client satisfaction. In addition, most of these program component ratings were not significantly associated among clients, caregivers, staff members, and administrators.

A short-term epidemiological study of median nerve dysfunction in practicing dental hygienists.

The purpose of this study was to assess over time changes in median nerve function in a group of 20 students who entered the University of Minnesota dental hygiene program in 1986. This is a follow-up report on 16 of the 20 students who were evaluated two years postgraduation in 1990. Comparisons were made with prior evaluations of the subjects completed at graduation in 1988, and one year postgraduation in 1989. Digital vibrometry was used to evaluate median nerve sensibility threshold at each of the time periods studied. Analysis revealed that after one year of clinical practice, there was a mean sensibility threshold shift of 11.04% in the left median nerve and 8.42% in the right median nerve as measured by digital vibrometry. Results at two years postgraduation indicated that the threshold shift observed in an earlier study had been arrested. The reasons appeared to be twofold: (1) a period of work hardening with a concept of neuromuscular ligamentous tissue hypertrophy or adaptation to the rigors of dental hygiene practice, and/or (2) the practicing dental hygienist had learned to become more efficient in the provision of hygiene procedures. There were no reported symptoms of median nerve dysfunction and none of the subjects had been diagnosed as having CTS at any time during the two years since graduation. Continued evaluations will be necessary to determine whether the observations noted during the second year postgraduation evaluation indicated temporary or permanent slowing of the conditions necessary for the development of CTS.

Threats to internal validity in worksite health promotion program research: common problems and possible solutions.

Reviews of the research on worksite health promotion programs reveal that most studies are limited in their ability to draw clear inferences about program effects because the studies employed flawed research designs and/or analyses. Conclusions are often drawn about program effectiveness with little consideration given to alternative explanations for the findings. In an effort to promote improved research, this article uses the Cook and Campbell delineation of threats to valid causal inference to illustrate how the threats can operate in worksite health promotion program research as well as how they can be examined and controlled. Researchers, even those attempting to conduct true experiments, must consider the existence of all plausible threats to validity and control or rule them out before valid causal inferences can be drawn. The theoretical and design issues involved in worksite health promotion program research are presented, followed by a discussion of threats to internal validity.
