The reliability and validity of two health status measures for evaluating outcomes of home care nursing.

The reliability, validity, and sensitivity of the Medical Outcome Study Short Form (SF-36) and the Quality of Life Profile: Senior Version (QOLPSV) for measuring outcomes of home care nursing were evaluated. Data were collected from 50 clients receiving home care nursing services. Twenty-two registered nurses and six registered practical nurses collected client and nursing data on each home visit. Client baseline and outcome measures were collected by two independent evaluators at admission and discharge from the home care service. Internal consistency reliability ranged from.76 to.94 for the eight subscales of the SF-36. Internal consistency reliability ranged from.47 to.82 for the nine subscales of the QOLPSV. The subscales of both instruments had minimal problems with missing responses. The SF-36 was found to be more sensitive than the QOLPSV to change over time. In addition, the subscales of the SF-36 were found to be more sensitive than the subscales of the QOLPSV to several of the nursing variables, such as intensity of the client's nursing condition and skill mix.

Multivariate modeling of missing data within and across assessment waves.

Missing data constitute a common but widely underappreciated problem in both cross-sectional and longitudinal research. Furthermore, both the gravity of the problems associated with missing data and the availability of the applicable solutions are greatly increased by the use of multivariate analysis. The most common approaches to dealing with missing data are reviewed, such as data deletion and data imputation, and their relative merits and limitations are discussed. One particular form of data imputation based on latent variable modeling, which we call Multivariate Imputation, is highlighted as holding great promise for dealing with missing data in the context of multivariate analysis. The recent theoretical extension of latent variable modeling to growth curve analysis also permitted us to extend the same kind of solution to the problem of missing data in longitudinal studies. Data simulations are used to compare the results of multivariate imputation to other common approaches to missing data.

Effects of an abilities-focused program of morning care on residents who have dementia and on caregivers.

OBJECTIVE: To conduct a controlled investigation to examine the effects of an abilities-focused program of morning care on the interaction behaviors and functioning of residents with dementia and on caregivers' interaction behaviors and perceptions of caregiving. DESIGN: A quasi-experimental, repeated measures design. SETTING: The study was conducted on four, nursing-home-level cognitive supports units in a geriatric care center. One of the units was randomly selected as the experimental unit; the other three served as controls. PARTICIPANTS: The final sample consisted of 40 residents (20 each in the experimental and three control groups) and 44 caregivers (16 on the experimental unit and 28 on the three control units). INTERVENTION: An educational program on delivering abilities-focused morning care, designed by the authors, was provided to caregivers on the experimental unit. MEASUREMENTS: Measures were taken at baseline and at 3 and 6 months postintervention with regard to residents' interaction behaviors, level of agitation, and level of function and to caregivers' interaction behaviors, perceived ease of caregiving, and level of stress. RESULTS: Repeated measures analysis of variance (RM-ANOVA) was used to compare the experimental and control groups in regard to changes in the outcomes over time. Results indicated that the abilities-focused program had statistically significant effects on (a) residents' personal attending and calm/functional behaviors, level of agitation, and levels of overall and social function, and (b) caregivers' verbal relevance and personal attending, relaxed, and social/flexible behaviors. CONCLUSIONS: The evidence suggests that both residents and caregivers benefit from morning care that is oriented toward the abilities of people with dementia.

A conceptual framework for evaluating the nurse practitioner role in acute care settings.

The conceptualization and enactment of the ACNP role varies across settings, potentially leading to variability in outcome achievement. A conceptual framework for evaluating the ACNP role is proposed. The framework is an adaptation of the Nursing Role Effectiveness Model which was developed to facilitate the identification and investigation of nursing-sensitive outcomes. The framework represents the complex system of interrelated factors that are present in the ACNP practice situation and that affect role effectiveness. It includes three components: (i) structure--encompassing patient, ACNP and organizational variables; (ii) process--consisting of the ACNP role components (clinician, educator, researcher and administrator) and the ways in which the role is enacted; and (iii) outcomes--including patient- and cost-related outcomes. The framework proposes specific relationships among the structure, process and outcomes components. Empirical support for the framework propositions is provided, based on a review of pertinent literature. Implications for future ACNP impact studies are discussed.

The therapeutic use of music for dyspnea and anxiety in patients with COPD who live at home.

The purposes of this repeated measures study were to examine the feasibility of using music as an intervention for dyspnea and anxiety in patients with chronic obstructive pulmonary disease (COPD) who live in their homes and to examine the effect of music on anxiety and dyspnea. Twenty-four participants who experienced dyspnea at least once a week were studied over a 5-week period. Baseline data were collected on Week 1. Measures of anxiety and dyspnea were taken on Week 2, prior to and immediately following the use of music. These measures were repeated on Week 5. There was a significant decrease in dyspnea following the use of music as reported in the music diary (p < .001). There was a significant decline in anxiety (p < .05) and dyspnea (p < .01) following the use of music on Week 2. There was no significant change in anxiety or dyspnea over the 5-week period.

Measuring the intervention in effectiveness research.

Inconsistent implementation of the intervention in the field setting presents a threat to the validity of the conclusions of an effectiveness study. Inconsistent implementation results in variability in the actual dosage of the intervention received by the participants, which leads to variability in outcomes achievement and, consequently, to Type II error. This article discusses the methodological implications of inconsistent intervention implementation and advances a strategy as a solution to this problem. The strategy proposes to quantify the dosage of the intervention as a continuous variable and to use this variable in the statistical analysis. The benefits of this strategy are illustrated with an empirical example from the Self-Help Intervention Project.

An abilities assessment instrument for elderly persons with cognitive impairment: psychometric properties and clinical utility.

In this article the psychometric properties of an Abilities Assessment Instrument (AAI), developed to assess the self-care, social, interactional and interpretive abilities of older people with cognitive impairment (CI) related to dementia, are described. The sample consisted of 112 institutionalized older men with CI and 60 institutionalized older men without CI. The psychometric evaluation of the AAI indicated that: (a) it is reliable in terms of test-retest (Pearson's r range .93-.99), interrater (Pearson's r range .95- .99), and internal consistency evaluations (Cronbach's alpha .90-.98), as well as through confirmatory factor analysis; and (b) that it is valid with respect to content validity (CVI 87.3%), concurrent validity (Pearson's r correlations ranging from -.67-.80 on the London Psychogeriatric Rating Scale [LPRS], and from -.76-.85 on the Functional Assessment Stages Scale [FAST]), and construct validity with significant differences between subjects with and without CI (t values ranging from 5.13-9.30). The AAI is a reliable and valid instrument that can be used to provide assessment data.

Use of the multitrait multimethod (MTMM) to analyze family relational data.

In this article, the authors propose the logic of the multitrait multimethod (MTMM) approach for analysis of data as an alternative solution for examining family relational data. Application of the MTMM logic permits the assessment of common perspectives shared by all family members and of the unique perspectives of individuals. The advantages of using this approach in family research include the ability to (a) maintain consistency between systems theory views of family-as-a-unit, and (b) delineate patterns of agreement, disagreement, or both among family members.

An analysis of the nurse practitioner role in palliative care.

The purpose of this study was to examine the nature and contribution of the nurse practitioner (NP) role in an oncology palliative clinic. Quantitative and qualitative data were collected from the practice of one NP. Data were obtained on the performance of the NP role functions. the characteristics of the patients seen by the NP, the interventions delivered by the NP, and the outcomes of care. Descriptive and content analyses were used to analyze the data. The results indicate that the NP in an oncology palliative care clinic engages primarily in the clinical component of the role. The emphasis is on symptom management, patient and family education and counseling, coordination of care, and maintaining continuity of care. The method followed in this case study to examine the contribution of the NP role could be used by other NPs to demonstrate the quality, effectiveness, and efficiency of their care.

Family medicine in Lebanon: the 10th anniversary.

Developing a family practice residency program was a logical step in addressing the needs for primary care in Lebanon. The American University of Beirut initiated a family practice residency program in 1979. The curriculum was structured following the guidelines of the American Academy of Family Physicians. Since its establishment, the program has participated in the design, launching, and maintenance of the family practice residency in Bahrain. Future plans include establishing other programs in the region and increasing community participation.

Linking outcomes to nurses' roles in health care.

As the health care industry refines quality assurance and quality improvement standards, the accountability of individual care providers is intensifying. Care providers work within a system of interdependent roles and functions and collaborate to attain the common goal of quality care. A conceptual model was developed which relates the achievement of specific outcomes to nurses' independent, dependent, and interdependent roles and functions. Empirical literature was used to identify outcomes associated with nurses' role functions. Outcomes associated with nurses' independent role functions included the prevention of complications, clinical outcomes, knowledge of diseases and treatments, satisfaction, and cost outcomes. Outcomes associated with nurses' dependent role included adverse incidents which caused problems or prolonged hospital stays. Outcomes associated with nurses' interdependent role included interdisciplinary team functioning.
