An analysis of the shortage of registered nurses (RNs) in acute care hospitals in El Paso, Texas

The purpose of this analysis of the shortage of Registered Nurses (RNs) in acute care hospitals in El Paso, Texas, was to evaluate twenty-two specific organizational and/or patient care unit (nursing unit) characteristics that effect the retention and turnover of professional nurses. Vacancy Rates were used to measure the level of the shortage in each hospital and nursing unit in the study. Vacancy Rates are a function of both RN retention and RN turnover. Seventy-three patient care units in five acute care hospitals were included in the study population.^ Fredrick Herzberg's motivational - hygiene theory was used to explain the types of characteristics or factors that can effect worker dissatisfaction. Dissatisfiers (hygiene factors) are those work place characteristics that influence workers to leave the job. The twenty-two potentially dissatisfying work place characteristics were either organizational or patient care unit specific in nature. The focus of the study was to evaluate high vacancy rates caused by both low retention of RNs and high turnover rates. Retention and turnover are a function of workers (RNs) not staying in their jobs, therefore hygiene factors were appropriate characteristics to study.^ Various multivariate analysis techniques were used to assess both the individual and combined effects of the hygiene factors on Vacancy Rates, Retention and Turnover. Results suggest that certain organizational and patient care unit characteristics are associated with and have a statistically significant effect on vacancy rates, and the retention and turnover of RNs. The type of Hospital was of particular interest in this regards. For-Profit facilities were less effected by most of the study variables than the Not-for-Profits. ^

Factors determining the use of universal precautions by emergency department nurses

The Health Belief Model (HBM) provided the theoretical framework for examining Universal Precautions (UP) compliance factors by Emergency Department nurses. A random sample of Emergency Nurses Association (ENA) clinical nurses (n = 900) from five states (New York, New Jersey, California, Texas, and Florida), were surveyed to explore the factors related to their decision to comply with UP. Five-hundred-ninety-eight (598) useable questionnaires were analyzed. The responders were primarily female (84.9%), hospital based (94.6%), staff nurses (66.6%) who had a mean 8.5 years of emergency nursing experience. The nurses represented all levels of hospitals from rural (4.5%) to urban trauma centers (23.7%). The mean UP training hours was 3.0 (range 0-38 hours). Linear regression was used to analyze the four hypotheses. The first hypothesis evaluating perceived susceptibility and seriousness with reported UP use was not significant (p = $>$.05). Hypothesis 2 tested perceived benefits with internal and external barriers. Both perceived benefits and internal barriers as well as the overall regression were significant (F = 26.03, p = $<$0.001). Hypothesis 3 which tested modifying factors, cues to action, select demographic variables, and the main effects of the HBM with self reported UP compliance, was also significant (F = 12.39, p = $<$0.001). The additive effects were tested by use of a stepwise regression that assessed the contribution of each of the significant variables. The regression was significant (F = 12.39, p = $<$0.001) and explained 18% of the total variance. In descending order of contribution, the significant variables related to compliance were: internal barriers (t = $-$6.267; p = $<$0.001) such as the perception that because of the nature of the emergency care environment there is sometimes inadequate time to put on UP; cues to action (t = 3.195; p = 0.001) such as posted reminder signs or verbal reminders from peers; the number of Universal Precautions training hours (t = 3.667; p = $<$0.001) meaning that as the number of training hours increase so does compliance; perceived benefits (t = 3.466; p = 0.001) such as believing that UP will provide adequate barrier protection; and perceived susceptibility (t = 2.880; p = 0.004) such as feeling that they are at risk of exposure. ^

The effectiveness of a needleless intravenous system in prevention of percutaneous injury in two hospitals

This study assessed if hospital-wide implementation of a needleless intravenous connection system reduces the number of reported percutaneous injuries, overall and those specifically due to intravenous connection activities.^ Incidence rates were compared before and after hospital-wide implementation of a needleless intravenous system at two hospitals, a full service general hospital and a pediatric hospital. The years 1989-1991 were designated as pre-implementation and 1993 was designated as post-implementation. Data from 1992 were not included in the effectiveness evaluation to allow employees to become familiar with use of the new device. The two hospitals showed rate ratios of 1.37 (95% CI = 1.22-1.54, p $\le$.0001) and 1.63 (95% CI = 1.34-1.97, p $\le$.0001), or a 27.1% and a 38.6% reduction in overall injury rate, respectively. Rate ratios for intravenous connection injuries were 2.67 (95% CI = 1.89-3.78, p $\le$.0001) and 3.35 (95% CI = 1.87-6.02, p $\le$.0001), or a 62.5% and a 69.9% reduction in injury rate, respectively. Rate ratios for all non-intravenous connection injuries were calculated to control for factors other than device implementation that may have been operating to reduce the injury rate. These rate ratios were lower, 1.21 and 1.44, demonstrating the magnitude of injury reduction due to factors other than device implementation. It was concluded that the device was effective in reduction of numbers of reported percutaneous injuries.^ Use-effectiveness of the system was also assessed by a survey of randomly selected device users to determine satisfaction with the device, frequency of use and barriers to use. Four hundred seventy-eight surveys were returned for a response rate of 50.9%. Approximately 94% of respondents at both hospitals expressed satisfaction with the needleless system and recommended continued use. The survey also revealed that even though over 50% of respondents report using the device "always" or "most of the time" for intravenous medication administration, flushing lines, and connecting secondary intravenous lines, needles were still being used for these same activities. Compatibility, accessibility and other technical problems were reported as reasons for using needles for these activities. These problems must be addressed, by both manufacturers and users, before the needleless system will be effective in prevention of all intravenous connection injuries. ^

A study of the cost and effect of newborn screening for Congenital Adrenal Hyperplasia in Texas

Congenital Adrenal Hyperplasia (CAH), due to 21-Hydroxylase deficiency, has an estimated incidence of 1:15,000 births and can result in death, salt-wasting crisis or impaired growth. It has been proposed that early diagnosis and treatment of infants detected from newborn screening for CAH will decrease the incidence of mortality and morbidity in the affected population. The Texas Department of Health (TDH) began mandatory screening for CAH in June, 1989 and Texas is one of fourteen states to provide neonatal screening for the disorder.^ The purpose of this study was to describe the cost and effect of screening for CAH in Texas during 1994 and to compare cases first detected by screen and first detected clinically between January 1, 1990 and December 31, 1994. This study used a longitudinal descriptive research design. The data was secondary and previously collected by the Texas Department of Health. Along with the descriptive study, an economic analysis was done. The cost of the program was defined, measured and valued for four phases of screening: specimen collection, specimen testing, follow-up and diagnostic evaluation.^ There were 103 infants with Classical CAH diagnosed during the study and 71 of the cases had the more serious Salt-Wasting form of the disease. Of the infants diagnosed with Classical CAH, 60% of the cases were first detected by screen and 40% were first detected because of clinical findings before the screening results were returned. The base case cost of adding newborn screening to an existing program (excluding the cost of specimen collection) was $357,989 for 100,000 infants. The cost per case of Classical CAH diagnosed, based on the number of infants first detected by screen in 1994, was \$126,892. There were 42 infants diagnosed with the more benign Nonclassical form of the disease. When these cases were included in the total, the cost per infant to diagnose Congenital Adrenal/Hyperplasia was $87,848. ^

The role of substance abuse treatment in preventing human immunodeficiency virus transmission among injecting drug users

This exploratory study assesses the utility of substance abuse treatment as a strategy for preventing human immunodeficiency virus (HIV) transmission among injecting drug users (IDUs). Data analyzed in this study were collected in San Antonio, TX, 1989 through 1995 using both qualitative and quantitative methods. Qualitative data included ethnographic interviews with 234 active IDUs; quantitative data included baseline risk assessments and HIV screening plus interviews follow-up interviews administered approximately six months later to 823 IDUs participating in a Federally-funded AIDS community outreach demonstration project.^ Findings that have particularly important implications for substance abuse treatment as an HIV prevention strategy for IDUs are listed below. (1) IDUs who wanted treatment were significantly more likely to be daily heroin users. (2) IDUs who want treatment were significantly more likely to have been to treatment previously. (3) IDUs who wanted treatment at baseline reported significantly higher levels of HIV risk than IDUs who did not want treatment. (4) IDUs who went to treatment between their baseline and follow-up interviews reported significantly higher levels of HIV risk at baseline than IDUs who did not go to treatment. (5) IDUs who went to treatment between their baseline and follow-up interviews reported significantly greater decreases in injection-related HIV risk behaviors. (6) IDUs who went to treatment reported significantly greater decreases in sexual HIV risk behaviors than IDUs who did not go to treatment.^ This study also noted a number of factors that may limit the effectiveness of substance abuse treatment in reducing HIV risk among IDUs. Findings suggest that the impact of methadone maintenance on HIV risk behaviors among opioid dependent IDUs may be limited by the negative manner in which it is perceived by IDUs as well as other elements of society. One consequence of the negative perception of methadone maintenance held by many elements of society may be an unwillingness to provide public funding for an adequate number of methadone maintenance slots. Thus many IDUs who would be willing to enter methadone maintenance are unable to enter it and many IDUs who do enter it are forced to drop out prematurely. ^

A quality of life subscale for terminally ill cancer patients

A subscale was developed to assess the quality of life of cancer patients with a life expectancy of six months or less. Phase I of this study identified the major concerns of 74 terminally ill cancer patients (19 with breast cancer, 19 with lung cancer, 18 with colorectal cancer, 9 with renal cell cancer, 9 with prostate cancer), 39 family caregivers, and 20 health care professionals. Patients interviewed were being treated at the University of Texas M. D. Anderson Cancer Center or at the Hospice at the Texas Medical Center in Houston. In Phase II, 120 patients (30 with breast cancer, 30 with lung cancer, 30 with colorectal cancer, 15 with prostate cancer, and 15 with renal cell cancer) rated the importance of these concerns for quality of life. Items retained for the subscale were rated as "extremely important" or "very important" by at least 60% of the sample and were reported as being applicable by at least two-thirds of the sample. The 61 concerns that were identified were formatted as a questionnaire for Phase III. In Phase III, 356 patients (89 with breast cancer, 88 with lung cancer, 88 with colorectal cancer, 44 with prostate cancer, and 47 with renal cell cancer) were interviewed to determine the subscale's reliability and sensitivity to change in clinical status. Both factor analysis and item response theory supported the inclusion of the same 35 items for the subscale. Internal consistency reliability was moderate to high for the subscale's domains: spiritual (0.87), existential (0.76), medical care (0.68), symptoms (0.67), social/family (0.66), and emotional (0.61). Test-retest correlation coefficients also were high for the domains: social/family (0.86), emotional (0.83), medical care (0.83), spiritual (0.75), existential (0.75), and symptoms (0.81).^ In addition, concurrent validity was supported by the high correlation between the subscale's symptom domain and symptom items from the European Organization for Research and Treatment of Cancer (EORTC) scale (r = 0.74). Patients' functional status was assessed with the Eastern Cooperative Oncology Group (ECOG) Performance status rating. When ECOG categories were compared to subscale domains, patients who scored lower in functional status had lower scores in the spiritual, existential, social/family, and emotional domains. Patients who scored lower in physical well-being had higher scores in the symptom domain. Patient scores in the medical care domain were similar for each ECOG category. The results of this study support the subscale's use in assessing quality of life and the outcomes of palliative treatment for cancer patients in their last six months of life. ^

Effect of continuous gastric enteral feeding on tonometric measurement of gastric intramucosal carbon dioxide levels in healthy volunteers

Purpose. The aim of this research was to evaluate the effect of enteral feeding on tonometric measurement of gastric regional carbon dioxide levels (PrCO2) in normal healthy volunteers. Design and methods. The sample included 12 healthy volunteers recruited by the University Clinical Research Center (UCRC). An air tonometry system monitored PrCO2 levels using a tonometer placed in the lumen of the stomach via orogastric intubation. PrCO2 was automatically measured and recorded every 10 minutes throughout the five hour study period. An oral dose of famotidine 40 mg was self-administered the evening prior to and the morning of the study. Instillation of Isocal® High Nitrogen (HN) was used for enteral feeding in hourly escalating doses of 0, 40, 60, and 80 ml/hr with no feeding during the fifth hour. Results . PrCO2 measurements at time 0 and 10 minutes (41.4 ± 6.5 and 41.8 ± 5.7, respectively) demonstrated biologic precision (Levene's Test statistic = 0.085, p-value 0.774). Biologic precision was lost between T130 and T140 40 when compared to baseline TO (Levene's Test statistic = 1.70, p-value 0.205; and 3.205, p-value 0.042, respectively) and returned to non-significant levels between T270 and T280 (Levene's Test statistic = 3.083, p-value 0.043; and 2.307, p-value 0.143, respectively). Isocal® HN significantly affected the biologic accuracy of PrCO2 measurements (repeated measures ANOVA F 4.91, p-value <0.001). After 20 minutes of enteral feeding at 40 ml/hr, PrCO2 significantly increased (41.4 ± 6.5 to 46.6 ± 4.25, F = 5.4, p-value 0.029). Maximum variance from baseline (41.4 ± 6.5 to 61.3 ± 15.2, F = 17.22, p-value <0.001) was noted after 30 minutes of Isocal® HN at 80 ml/hr or 210 minutes from baseline. The significant elevations in PrCO2 continued throughout the study. Sixty minutes after discontinuation of enteral feeding, PrCO2 remained significantly elevated from baseline (41.4 ± 6.5 to 51.8 ± 9.2, F = 10.15, p-value 0.004). Conclusion. Enteral feeding with Isocal® HN significantly affects the precision and accuracy of PrCO2 measurements in healthy volunteers. ^

Culturally sensitive cancer education: Effect on knowledge, cancer fatalism, and participation in mobile mammography screening among African-American women

Purpose. To evaluate the effectiveness of a culturally sensitive educational intervention that used an African American lay survivor of breast cancer to increase knowledge of breast cancer, decrease cancer fatalism, and increase participation in mobile mammography screening among African American women. ^ Design. Experimental pretest/posttest design. ^ Setting. Two predominantly African American churches in a large southwestern metropolitan city. ^ Sample. Participants included 93 African American women, 40 years of age and older. Participants were randomly assigned to an intervention group (n = 48) or a control group (n = 45). ^ Methods. Pretest and post-test measures included the Breast Cancer Knowledge Test and the Powe Fatalism Inventory. In addition, demographic and breast screening practices were collected by questionnaire. The intervention group received a breast cancer educational testimonial from an African American lay survivor of breast cancer, who answered questions and addressed concerns, while stressing the importance of taking responsibility for one's own health and spreading disease prevention messages throughout the African American community. The control group viewed the American Cancer Society “Keep In Touch” video prepared specifically for African American women. Participants in both groups were given culturally sensitive educational materials designed to increase knowledge about breast cancer, and were instructed on breast self-examination by an African American registered nurse, using ethnically appropriate breast models. In addition, after the post-test, all eligible participants were given an opportunity to have a free mammogram via a mobile mammography unit parked at the church. ^ Findings. Participants in the intervention group had a significant increase (p = .03) in knowledge of breast cancer and a significant decrease (p = .000) in fatalism scores compared to those individuals in the control group. The intervention group had a 61% participation rate in screening, while the control group had a 39% participation rate in screening. However, the difference was not statistically significant at the .05 level (p = .07). ^ Conclusions. Results demonstrate that culturally sensitive breast cancer education is successful in increasing knowledge and decreasing cancer fatalism. While there was a trend toward behavior change in the intervention group, more research needs to be done in this area. ^

The pain experience of elderly hospice patients with cancer

Purpose/objectives. A grounded theory design was used to identify, describe, and generate a theoretical analysis of the pain experience of elderly hospice patients with cancer. ^ Sample. Eleven participants over the age of 65, receiving services from a for-profit hospice were interviewed in their homes. ^ Methods. Broad unstructured face to face audio-taped interviews were transcribed verbatim and analyzed using constant-comparative method of analysis. ^ Findings. Pain was described as a hierarchy of chronic, acute, and psychological pain with psychological pain as the worst. Suffering was the basic social problem of pain. Participants dealt with suffering by the basic social process of enduring. Enduring had two sub-processes, maintaining hope and adjusting. Trusting in a higher being and finding meaning were mechanisms of maintaining hope. Mechanisms of adjusting were dealing with uncertainty, accepting, and minimizing pain. ^ Implications for nursing practice. Nurses need to recognize and value the hard work of enduring to deal with suffering. Assisting elderly hospice patients with cancer to address the sub-processes of enduring and their mechanisms can foster enduring. ^

Developmental aspects of synaesthesia across the adult lifespan

In synaesthesia, stimuli such as sounds, words or letters trigger experiences of colors, shapes or tastes and the consistency of these experiences is a hallmark of this condition. In this study we investigate for the first time whether there are age-related changes in the consistency of synaesthetic experiences. We tested a sample of more than 400 grapheme-color synaesthetes who have color experiences when they see letters and/or digits with a well-established test of consistency. Our results showed a decline in the number of consistent grapheme-color associations across the adult lifespan. We also assessed age-related changes in the breadth of the color spectrum. The results showed that the appearance of primary colors (i.e., red, blue, and green) was mainly age-invariant. However, there was a decline in the occurrence of lurid colors while brown and achromatic tones occurred more often as concurrents in older age. These shifts in the color spectrum suggest that synaesthesia does not simply fade, but rather undergoes more comprehensive changes. We propose that these changes are the result of a combination of both age-related perceptual and memory processing shifts.

Internal and external effects on cognition: Evidence from memory training in very preterm-born children and cognition in patients with carotid artery stenosis before and after treatment

The present synopsis aims to integrate one study about memory training in very preterm-born children and two studies about cognition in patients with carotid artery stenosis before and after treatments. Preterm-born children are at increased risk of cognitive deficits and behavioural problems compared with peers born at term. This thesis determined whether memory training would improve cognitive functions in school-age very preterm-born children. Memory strategy training produced significant improvements in trained and non-trained cognitive functions; a core working memory training revealed significant effects on short-term memory and working memory tasks. Six months after training, children in both training groups showed better working memory performance than children in the waiting control group. This is evidence that memory training – an external influence on cognition – induces plastic changes in very preterm-born children. Patients with carotid artery stenosis are known to be at increased risk of cognitive impairment. We showed that patients with symptomatic or asymptomatic carotid artery stenosis were at higher risk for cognitive deficits than expected in a normative sample. This thesis seeks to link cognitive plasticity to internal factors like carotid stenosis. An external factor, which influences blood flow to the brain is the nature of the carotid artery stenosis treatment. Research on the effects of carotid artery stenosis treatment on cognition has produced inconsistent results. We found significant improvement in frontal lobe functions, visual memory and motor speed one year after treatment independent of the treatment type (best medical treatment, carotid artery stenting, carotid artery endarterectomy); providing evidence for ‘treatment-induced’ cognitive plasticity. Baseline performance was negatively associated with improvement in various cognitive functions after training in very preterm-born children and after treatment in patients with carotid artery stenosis. The present synopsis aims to integrate these findings into the current and relevant literature, and discuss consequences as well as methodological considerations resulting from the studies constituting the thesis at hand.

Zuni elders: Ethnography of American Indian aging

Problem/purpose. The specific aim of this focused ethnography was to provide insight into the experience of aging of the American Indian (AI) elder as demonstrated by one tribe, the Zuni of New Mexico. Discovering how Zuni elders construct the experience of aging and the associated behaviors allowed the researcher to deconstruct aging and then re-present it in a cogent description for this population. Such a description is lacking in the literature and will be useful in planning for culturally relevant eldercare services. ^ Methods. Ethnographic field techniques were used to sample from elders, pueblo members-at-large, activities, events and places. Over 1800 hrs were spent in the field spanning 14 months and five site visits, with the longest at almost 4 weeks. Developing codes for transcribed interviews, field notes, supplementary documents, photographs, videos, and artifacts was carried out during analysis. Categories and ultimately a cognitive map and model were developed which represented aging in Zuni Pueblo in 2000. ^ Findings. Zuni elders are aging in two worlds. Their primary world has been described as a sevenfold universe, a complicated structure with seven planes wherein the middle plane refers to themselves, a synthesis of all the other planes. The increasing influence of the white world has formed a ‘new middle’ out of which everyday aspects of aging are viewed. ^ Implications for nursing/gerontology. Nurses and others in gerontology must recognize that vast differences in worldviews are present between themselves and AI elders regarding health practices, spirituality, eating patterns, family roles, medicine, religion and countless other aspects of life. Their centuries old beliefs and practices drive these differences coupled with a collision with the white world. Making a paradigm shift using an appropriate lens with which to view these differences can only increase our understanding and efficacy in delivering culturally relevant care. ^

The illness experiences of patients and their family members living with congestive heart failure

Purpose. To investigate and understand the illness experiences of patients and their family members living with congestive heart failure (CHF). ^ Design. Focused ethnographic design. ^ Setting. One outpatient cardiology clinic, two outpatient heart failure clinics, and informants' homes in a large metropolitan city located in southeast Texas. ^ Sample. A purposeful sampling technique was used to select a sample of 28 informants. The following somewhat overlapping, sampling strategies were used to implement the purposeful method: criterion; typical case; operational construct; maximum variation; atypical case; opportunistic; and confirming and disconfirming case sampling. ^ Methods. Naturalistic inquiry consisted of data collected from observations, participant observations, and interviews. Open-ended semi-structured illness narrative interviews included questions designed to elicit informant's explanatory models of the illness, which served as a synthesizing framework for the analysis. A thematic analysis process was conducted through domain analysis and construction of data into themes and sub-themes. Credibility was enhanced through informant verification and a process of peer debriefing. ^ Findings. Thematic analysis revealed that patients and their family members living with CHF experience a process of disruption, incoherence, and reconciling. Reconciling emerged as the salient experience described by informants. Sub-themes of reconciling that emerged from the analysis included: struggling; participating in partnerships; finding purpose and meaning in the illness experience; and surrendering. ^ Conclusions. Understanding the experiences described in this study allows for a better understanding of living with CHF in everyday life. Findings from this study suggest that the experience of living with CHF entails more than the medical story can tell. It is important for nurses and other providers to understand the experiences of this population in order to develop appropriate treatment plans in a successful practitioner-patient partnership. ^

Resting and reactive blood pressure as predictors of ambulatory blood pressure in older hypertensive adults

Background. A review of the literature suggests that Hypertension (HTN) in older adults is associated with sympathetic stimulation that results in increasing blood pressure (BP) reactivity. If clinical assessment of BP captured sympathetic stimulation, it would be valuable for hypertension management. ^ Objectives. The study examined whether reactive change scores from a short BPR protocol, resting blood pressure (BP), or resting pulse pressure (PP) is a better predictor of 24 hour ambulatory BP and BP load in cardiac patients. ^ Method. The study used a single-group design, with both an experimental clinical component and an observational field component. Both components used repeated measurement methods. The study population consisted of 45 adult patients with a mean age of 64.6 ± 8.5 years who were diagnosed with cardiac disease and who were taking anti-hypertensive medication. Blood pressure reactivity was operationalized with a speech protocol. During the speech protocol, BP was measured with an automatic device (Dinamap 825XT) while subjects talked about their health and about their usual day. Twenty-four hour ambulatory BP measurement (Spacelabs 90207 monitor) followed the speech protocol. ^ Results. Resting SBP and resting PP were significant predictors of 24-hour SBP, and resting SBP was a significant predictor of SBP load. No predictors were significant of 24-hour DBP or DBP load. ^ Conclusions. Initial resting BP and PP may be used in clinical settings to assess hypertension management. Future studies are necessary to confirm the ability of resting BP to predict ABP and BP load in older, medicated hypertensives. ^

The illness narratives of Hispanic American women with coronary heart disease (CHD): An ethnographic approach

Purpose. To provide a descriptive representation of the illness narratives described by Hispanic American women with CHD. ^ Design. Focused ethnographic design. ^ Setting. One outpatient general medicine clinic, one nurse-managed health promotion clinic, and informants' homes in a large metropolitan city located in southeast Texas. ^ Sample. Purposeful sampling from two different sites resulted in 17 interviews being conducted with 14 informants. ^ Method. Focused ethnographic techniques were employed in the designation of participants for the study, data collection, analysis and re-presentation. Audiotaped interviews and fieldwork were transcribed verbatim and analyzed through an iterative process of data reduction, data display, drawing conclusions and verification. ^ Findings. The developing conceptual framework that emerged from the data is labeled after the overarching experience described by informants, the experience of Embodied Exhaustion. Embodied Exhaustion, as described in this study, refers to an ongoing, dynamic, indeterminate experience of mind-body exhaustion resulting from a complex constellation of biologic, psychological and social distresses occurring over the life course. The experience consists of three categories: Taking Care of Others, Wearing Down and Hurting Hearts. Two stabilizing forces were identified: Collective Self and Believing in God. ^ Conclusions. The findings of this study emphasize the importance of framing all research, theory and practice targeting Hispanic women with CHD within a sociocentric paradigm. Nursing is challenged to provide care that extends beyond the physical body of the patient to include the social context of illness, especially the family. ^
