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. ^

An ethnographic study of home remedy use for African-American children

Background and significance. The use of herbs and other remedies by adult and elderly African-Americans has been documented. However, little is understood regarding the use of herbs for African-American children. The purpose of this study was to document and describe the historical and present day uses of herbal and other remedies, specifically for the health and illness of African-American children. This information will provide health care providers with a better understanding of their African-American patients. This information may also contribute to the emerging appreciation of indigenous uses of phytotherapeutics. ^ Methods. A focused ethnographic approach was used to describe the cultural context, including the beliefs, values, customs, and behaviors of a particular culture. The use of intensive fieldwork, including participant observation, audiotaped formal interviews, photographs, and specimen collection of plants helped to describe herb use in this population. Information on the growing, harvesting, preparation, and storage of these plant remedies, as well as the amount and dosage of these compounds was collected in a typology. Detailed information was gathered to discern how, when, and under what conditions these remedies were used and their expected results. Further data collection focused on the history of herbal use, and explanations for how and why informants thought the herbs work. ^ Setting and participants. The setting for this study was in East Texas and field work extended over the period of one year. Thirty African-Americans, age 38 to 98, were interviewed for the study. The African-American population in this area has been relatively stable, with roots dating back prior to the reconstruction period, which allowed excellent historical information. Informants were chosen by a nominated sampling technique starting with two key informants knowledgeable about the use of home remedies for children. ^ Findings. The findings of this study suggest that African-American children in East Texas have a long history of receiving herbs and home remedies for health promotion and illness. Data further suggests that there is a strong connection between spirituality and the health beliefs and practices of this community. This spiritual component underlies the accuracy of oral recall for remedies that have been used over many generations and the use of natural folk remedies. A typology of the herbal remedies was developed with folk and Latin name, herb place of origin, known scientific properties, and informant folk usage and dosage information. ^

Assessment of readiness to initiate antiretroviral therapy

An important factor in determining a patient's adherence to antiretroviral therapy is the patient's commitment to follow the regimen. This suggests that therapy should be initiated when the patient is willing to commit to the regimen. Starting when the patient is ready may be more important than the laboratory values suggested by various guidelines. In order to increase understanding of patient readiness for antiretroviral therapy HIV infected patients were surveyed to determine the factors that influenced their decision to initiate antiretroviral therapy and to continue to adhere to therapy once started. A sample of 83 HIV infected patients who were currently on antiretroviral regimens completed a 25-item investigator-developed questionnaire. The questionnaire sought information on the length of time from learning of HIV positive status and readiness to initiate therapy. The questionnaire also addressed demographic, psychological and social factors thought to be associated with readiness for adhering to therapy. (Abstract shortened by UMI.)^

Barriers and facilitators to nurses' acceptance of and implications for injury rates of an IV catheter safety device

This study has the purpose of determining the barriers and facilitators to nurses' acceptance of the Johnson and Johnson Protectiv®* Plus IV catheter safety needle device and implications for needlestick injuries at St. Luke's Episcopal Hospital, Houston, Texas. A one-time cross-sectional survey of 620 responding nurses was conducted by this researcher during December, 2000. The study objectives were to: (1) describe the perceived (a) organizational and individual barriers and facilitators and (b) acceptance of implementation of the IV catheter device; (2) examine the relative importance of these predictors; (3) describe (a) perceived changes in needlestick injuries after implementation of the device; (b) the reported incidence of injuries; and (c) the extent of underreporting by nurses; and (4) examine the relative importance of (a) the preceding predictors and (b) acceptance of the device in predicting perceived changes in needlestick injuries. Safety climate and training were evaluated as organizational factors. Individual factors evaluated were experience with the device, including time using it and frequency of use, and background information, including nursing unit, and length of time as a nurse in this hospital and in total nursing career. The conceptual framework was based upon the safety climate model. Descriptive statistics and multiple and logistic regression were utilized to address the study objectives. ^ The findings showed widespread acceptance of the device and a strong perception that it reduced the number of needlesticks. Acceptance was notably predicted by adequate training, appropriate time between training and device use, solid safety climate, and short length of service, in that order. A barrier to acceptance was nurses' longtime of use of previous needle technologies. Over four-fifths of nurses were compliant in always using the device. Compliance had two facilitators: length of time using device and, to a lesser extent, safety climate. Rates of compliance tended to be lower among nurses in units in which the device was frequently used. ^ High quality training and an atmosphere of caring about nurse safety stand out as primary facilitators that other institutions would need to adopt in order to achieve maximum success in implementing safety programs involving utilization of new safety devices. ^

The relationship between leadership practices and a medication safety regime

Errors in healthcare are commonplace and have significant impact on mortality, morbidity, and costs. Other high-risk industries are credited with strong safety records. These successes are due in part to a strong, committed organizational culture and their leadership. A consistent pattern of effective leadership behaviors; creating change, establishing a vision and strategic actions, and enabling and inspiring the organization's members to act, is present in these high-risk industries. This research examined the relationship between leadership practices and a medication safety regime. The hypothesis is strong leadership practices have a positive relationship with the degree of sophistication of a medication safety program (safety performance). Leadership was used as a surrogate for organizational culture and was measured in this research through the Kouzes and Posner's Leadership Practices Inventory. The Institute of Medicine's 14 Selected Strategies to Improve Medication Safety was used to measure the development of a medication safety regime. Leadership practices towards safety were assessed by surveying 2,478 critical care Registered Nurses in the greater Houston area. A response rate of 19% was achieved. Thirteen hospitals participated in the medication safety regime assessment. Data from 386 RN respondents from 53 institutions provided an overall description of unit (ICU) and organization (hospital) leader's practices towards safety. There is some recognition of the medical error problem and that leaders exhibit moderate levels of leadership practices to promote safety. There were no differences noted in unit and hospital leaders' behaviors, with the exception that unit leaders promote change and enable staff to act more often than hospital leaders. There were no statistically significant relationships between overall leadership, or individual leadership practices and the organization's safety performance. There was a significant relationship between leadership and safety performance when other factors in organizational culture were considered. Teaching and Magnet hospitals also exhibited stronger behaviors towards safety. Organizational culture, as measured by academic affiliation and Magnet recognition, is strongly related to safety performance as measured by the degree of development of a medication safety regime. ^

Adherence to a lifestyle physical activity program: Trends over time and associations with processes of change and physical activity

Research on lifestyle physical activity interventions suggests that they help individuals meet the new recommendations for physical activity made by the Centers for Disease Control and Prevention (CDC) and the American College of Sports Medicine (ACSM). The purpose of this research was to describe the rates of adherence to two lifestyle physical activity intervention arms and to examine the association between adherence and outcome variables, using data from Project PRIME, a lifestyle physical activity intervention based on the transtheoretical model and conducted by the Cooper Institute of Aerobics Research, Dallas, Texas. Participants were 250 sedentary healthy adults, aged 35 to 70 years, primarily non-Hispanic White, and in the contemplation and preparation stages of readiness to change. They were randomized to a group (PRIME G) or a mail- and telephone-delivered condition (PRIME C). Adherence measures included attending class (PRIME G), completing a monthly telephone call with a health educator (PRIME C), and completing homework assignments and self-monitoring minutes of moderate- to vigorous physical activity (both groups). In the first results paper, adherence over time and between conditions was examined: Attendance in group, completing the monthly telephone call, and homework completion decreased over time, and participants in PRIME G were more likely to complete homework than those in PRIME C. Paper 2 aimed to determine whether the adherence measures predicted achievement of the CDC/ACSM physical activity guideline. In separate models for the two conditions, a latent variable measuring adherence was found to predict achievement of the guideline. Paper 3 examined the association between adherence measures and the transtheoretical model's processes of change within each condition. For both, participants who completed at least two thirds of the homework assignments improved their use of the processes of change more than those who completed less than that amount. These results suggest that encouraging adherence to a lifestyle physical activity intervention, at least among already motivated volunteers, may increase the likelihood of beneficial changes in the outcomes. ^

Temporal variations of dyspnea, fatigue, and lung function in chronic lung disease

Background. Research investigating symptom management in patients with chronic obstructive pulmonary disease (COPD) largely has been undertaken assuming the homeostatic construct, without regard to potential roles of circadian rhythms. Temporal relations among dyspnea, fatigue, peak expiratory flow rate (PEFR) and objective measures of activity/rest have not been reported in COPD. ^ Objectives. The specific aims of this study were to (1) explore the 24-hour patterns of dyspnea, fatigue, and PEFR in subjects with COPD; (2) examine the relations among dyspnea, fatigue, and PEFR in COPD; and (3) examine the relations among objective measures of activity/rest and dyspnea, fatigue, and PEFR in COPD. ^ Methods. The repeated-measures design involved 10 subjects with COPD who self-assessed dyspnea and fatigue by 100 mm visual analog scales, and PEFR by peak flow meter in their home 5 times a day for 8 days. Activity/rest was measured by wrist actigraphy. Single and population mean cosinor analyses and correlations were computed for dyspnea, fatigue, and PEFR; correlations were done among these variables and activity/rest. ^ Results. Circadian rhythms were documented by single cosinor analysis in 40% of the subjects for dyspnea, 60% for fatigue, and 60% for PEFR. The population cosinor analysis of PEFR yielded a significant rhythm (p < .05). The 8-day 24-hour means of dyspnea and fatigue was moderately correlated (r = .48, p < .01). Dyspnea and PEFR, and fatigue and PEFR, were weakly correlated in a negative way (r = −.11, p < .05 and r = −.15, p < .01 respectively). Weak to moderate correlations (r = .12–.34, p < .05) were demonstrated between PEFR and mean activity level measured up to 4 hours before PEFR measurement. ^ Conclusions. The findings suggest that (1) the dyspnea and fatigue experienced by COPD patients are moderately related, (2) there is a weak to modest positive relation between PEFR and activity levels, and (3) temporal variation in lung function may not affect the dyspnea and fatigue experienced by patients with COPD. Further research, examining the relations among dyspnea, fatigue, PEFR, and activity/rest is needed. Replication of this study is suggested with a larger sample size. ^

Outcomes and cost effectiveness of treating type 2 diabetes with a nurse case manager following treatment algorithms versus primary care physicians

Background. Diabetes places a significant burden on the health care system. Reduction in blood glucose levels (HbA1c) reduces the risk of complications; however, little is known about the impact of disease management programs on medical costs for patients with diabetes. In 2001, economic costs associated with diabetes totaled $100 billion, and indirect costs totaled $54 billion. ^ Objective. To compare outcomes of nurse case management by treatment algorithms with conventional primary care for glycemic control and cardiovascular risk factors in type 2 diabetic patients in a low-income Mexican American community-based setting, and to compare the cost effectiveness of the two programs. Patient compliance was also assessed. ^ Research design and methods. An observational group-comparison to evaluate a treatment intervention for type 2 diabetes management was implemented at three out-patient health facilities in San Antonio, Texas. All eligible type 2 diabetic patients attending the clinics during 1994–1996 became part of the study. Data were obtained from the study database, medical records, hospital accounting, and pharmacy cost lists, and entered into a computerized database. Three groups were compared: a Community Clinic Nurse Case Manager (CC-TA) following treatment algorithms, a University Clinic Nurse Case Manager (UC-TA) following treatment algorithms, and Primary Care Physicians (PCP) following conventional care practices at a Family Practice Clinic. The algorithms provided a disease management model specifically for hyperglycemia, dyslipidemia, hypertension, and microalbuminuria that progressively moved the patient toward ideal goals through adjustments in medication, self-monitoring of blood glucose, meal planning, and reinforcement of diet and exercise. Cost effectiveness of hemoglobin AI, final endpoints was compared. ^ Results. There were 358 patients analyzed: 106 patients in CC-TA, 170 patients in UC-TA, and 82 patients in PCP groups. Change in hemoglobin A1c (HbA1c) was the primary outcome measured. HbA1c results were presented at baseline, 6 and 12 months for CC-TA (10.4%, 7.1%, 7.3%), UC-TA (10.5%, 7.1%, 7.2%), and PCP (10.0%, 8.5%, 8.7%). Mean patient compliance was 81%. Levels of cost effectiveness were significantly different between clinics. ^ Conclusion. Nurse case management with treatment algorithms significantly improved glycemic control in patients with type 2 diabetes, and was more cost effective. ^

A focused ethnographic study of community social capital

Social capital, a relatively new public health concept, represents the intangible resources embedded in social relationships that facilitate collective action. Current interest in the concept stems from empirical studies linking social capital with health outcomes. However, in order for social capital to function as a meaningful research variable, conceptual development aimed at refining the domains, attributes, and boundaries of the concept are needed. An existing framework of social capital (Uphoff, 2000), developed from studies in India, was selected for congruence with the inductive analysis of pilot data from a community that was unsuccessful at mobilizing collective action. This framework provided the underpinnings for a formal ethnographic research study designed to examine the components of social capital in a community that had successfully mobilized collective action. The specific aim of the ethnographic study was to examine the fittingness of Uphoff's framework in the contrasting American community. A contrasting context was purposefully selected to distinguish essential attributes of social capital from those that were specific to one community. Ethnographic data collection methods included participant observation, formal interviews, and public documents. Data was originally analyzed according to codes developed from Uphoff's theoretical framework. The results from this analysis were only partially satisfactory, indicating that the theoretical framework required refinement. The refinement of the coding system resulted in the emergence of an explanatory theory of social capital that was tested with the data collected from formal fieldwork. Although Uphoff's framework was useful, the refinement of the framework revealed, (1) trust as the dominant attribute of social capital, (2) efficacy of mutually beneficial collective action as the outcome indicator, (3) cognitive and structural domains more appropriately defined as the cultural norms of the community and group, and (4) a definition of social capital as the combination of the cognitive norms of the community and the structural norms of the group that are either constructive or destructive to the development of trust and the efficacy of mutually beneficial collective action. This explanatory framework holds increased pragmatic utility for public health practice and research. ^

Evaluating the March of Dimes NICU Family Support Program: Parent Support for Neonatal Transport

The purpose of the pilot study was to work in collaboration with the March of Dimes Family Support Team and the University of Connecticut Health Center (UCHC) to develop an evaluation instrument for the assessment of the Transport Module implemented by The March of Dimes Neonatal Intensive Care Unit (NICU) Family Support Program initiative at the UConn Health Center. A literature review of the topic illustrated the need for continuing research of successful family support interventions for parents experiencing the transport of their high-risk infant to a tertiary care NICU immediately after delivery. NICU staff members and the March of Dimes Organization can utilize the evaluation instrument created for this study to identify parent support needs and the effectiveness of module implementation across the country. Effective family support will increase parent confidence and decrease anxieties that are often associated with the birth of a pre-term infant.

Evaluation of the March of Dimes Family Support Program with Focus on Parent to Parent Support

The March of Dimes NICU Family Support Program provides families with support specialists, educational materials, and community resources to aide in the emotional and physical adaptation to a new life with a premature infant. Parent-to-parent support has been shown to more effective than group support because the new NICU parent is able to connect on a more personal level with an experienced NICU parent. The purpose of the research was to develop and implement an evaluation instrument to assess the effectiveness of the March of Dimes NICU Family Support Program (MODFSP) in the NICU at the UConn Health Center, specifically parent-to-parent support. Steps involved in the process included determining areas of focus for the instrument, developing items based on MODFSP materials and literature review, piloting the materials on parents with infants in the NICU (with IRB approval), and utilizing descriptive statistics through SPSS Version 14 to assess the results from the instrument content. Qualitative items were also included in the evaluation, and descriptive qualitative methods, as appropriate, were used to analyze those items. The findings have supported the literature in that all parents that participated in parent to parent support agreed the program was beneficial in assisting them with their transition to life with a premature infant. In addition to evaluating the new NICU parent’s opinions of the program, researchers evaluated the staff and volunteer parents that were involved in the program. The results also revealed that the new NICU parent’s fear, anxiety, and stress decreased after the parent-to-parent interactions. The preliminary results were encouraging that the MODFSP has implemented an effective parent-to-parent support program to support parents through their time of crisis.

The meaning of informal BMT caregiving

Objectives. The aims of this qualitative descriptive exploratory study were to (1) describe informal caregiver commitment in informal caregiving; (2) describe caregiver expectations in informal caregiving; (3) describe caregiver role negotiation in informal caregiving, (4) identify other important caregiver energy sources; and (5) refine the conceptual model of Informal Caregiving Dynamics based on the study results. ^ Methods. Participants were 40 informal caregivers of blood and marrow transplant patients being treated at a comprehensive cancer center who told their caregiving stories in an audiotaped dialogue. Patients consented to have their caregivers contacted about the study and to have information collected from their medical records. To address the specific aims, the dialogues were analyzed for major elements and themes with an adaptation of the descriptive exploratory method. ^ Findings. Commitment was redefined as enduring caregiver responsibility that inspires life changes to make the patient a priority. Commitment calls caregivers to supportive presence and self-affirming loving connection with the patient. Expectation management was defined as envisioning the future and yearning to return to normal. Expectation management includes taking one day at a time, gauging behavior from past experiences with the patient, and reconciling anticipated to actual treatment twists and turns. Role negotiation was defined as appropriate pushing by the caregiver toward patient recovery and independence after getting a handle on complex care that demands shared responsibilities. Role negotiation happens as caregivers determine action with attention to patient voice and vigilantly bridge communication between patients and the health care system. Three additional energy sources of caring for self, gaining insight, and connecting with others, were identified and added to the model as underpinnings for commitment, expectation, and role negotiation respectively. ^ Discussion and implications. Methods of supporting informal caregivers that deserve investigation include consistent acknowledgment of caregiver contribution to patient care; provision of clear, present-focused information; opportunities to reconcile expectations with outcomes by developing a coherent caregiving story; and encouragement to maintain good health habits while caregiving. Patient contribution to the dynamics of caregiving warrants future research attention as does change in energy sources over time as a caregiver. ^

A focused ethnographic study of women in recovery from alcohol abuse

Alcohol abuse and its related problems are among the most pervasive health and social concerns in the United States (U.S.) today. Women are especially vulnerable to the physical and social devastation of alcohol abuse. Yet, although there is extensive research about alcohol drinking patterns, treatment strategies, and early recovery, there is little information about the factors that facilitate successfully sustained abstinence in women. The purpose of this study was to examine and describe the common factors to successful recovery from alcohol abuse among women and to place these factors within both the context of their social networks and the larger social environment. This study draws from the population of New Mexico, where alcohol-related deaths are the highest of any state in the U.S. and the leading cause of death for individuals under the age of 65 years. The study was a focused ethnography of women who had successfully maintained long-term recovery from alcohol abuse. As an ethnographic study, data collection included participant observation, in-depth interviews with 21 women, and the collection of historical and current culturally relevant data. A purposive sampling plan was used to maximize the selection of participants who had used traditional and non-traditional approaches to recovery. As such, the analysis of the success narratives revealed two distinct findings: the first that women used several different trajectories to achieve long-term recovery. Three trajectory typologies were identified from the success narratives and labeled, A.A. as ceremony, A.A. as grounding, and Recovery as self-management. ^ However, within each of these trajectories, variations in successful recovery were seen. The second major finding was that all women articulated an overarching theme of connections as an indispensable aspect of sustained recovery. The success narratives demonstrated the powerful role that connections played in their long-term recovery and the analysis distinguished two unifying concepts of connections—those that focused beyond self (spirituality, social support, and pets) and those that focused toward self (self-nurturance, agency, and identity). This discussion will focus on the implications for clinical practice related to both women who are still actively abusing alcohol and for those who are successfully maintaining long-term recovery. ^

Factors affecting the symptom burden in chronic heart failure

Background. Heart failure (HF) is a health problem of epidemic proportions and a clinical syndrome that leads to progressively severe symptoms, which contribute significantly to the burden of the disease. Several factors may affect the symptom burden of patients with HF, including physiological, psychological, and spiritual factors. This study was designed to examine the inter-relationship of physiological, psychological, and spiritual factors affecting symptoms for patients with HF. ^ Objectives. The aims of this study were to examine symptom burden of heart failure patients related to: (1) the physiological factor of brain natriuretic peptide (BNP); (2) the psychological factor of depression; (3) the spiritual factors of self transcendence and purpose in life; and (4) combined effects of physiological, psychological and spiritual factors. One additional aim was to describe symptom intensity related to symptom burden. ^ Methods. A cross-sectional non-experimental correlational design was used to examine factors affecting symptom burden in 105 patients with HF from a southwestern medical center outpatient heart failure clinic. Both men and women were included; average age was 56.6 (SD = 16.86). All measures except BNP were obtained by patient self-report. ^ Results. The mean number of symptoms present was 8.17 (SD = 3.34) with the three most common symptoms being shortness of breath on exertion, fatigue, and weakness. The mean symptom intensity was 365.66 (SD = 199.50) on a summative scale of visual analogue reports for 13 symptoms. The mean BNP level was 292.64 pg/ml (SD = 57 1.11). The prevalence rate for depression was 43.6% with a mean score of 3.48 (SD = 2.75) on the Center for Epidemiological Studies - Depression scale (CES-D 10) scale. In a multivariate analysis, depression was the only significant predictor of symptom burden (r = .474; P < .001), accounting for 18% of the variance. Spirituality had an interaction effect with depression (P ≤ .001), serving as a moderator between depression and symptom burden. ^ Conclusion. HF is a chronic and progressive syndrome characterized by severe symptoms, hospitalizations and disability. Depression is significantly related to symptom burden and this relationship is moderated by spirituality. ^

The impact of a brief foot care intervention for persons with diabetes

Purpose of the study. The purpose of this randomized controlled clinical trial was to determine if a brief intervention would improve foot self-care behaviors in adult patients with Type 2 diabetes who presented to the emergency department for non-emergent care in a predominantly Hispanic southwestern border community. ^ Methods. A pre-post-test, three-group design was used to compare the foot self-care behaviors of patients who received usual care to those who received lower extremity amputation (LEA) risk assessment and to those who received LEA risk assessment plus a brief foot self-care intervention. After being randomized into 3 groups (N = 167), baseline assessments of demographics, diabetes history, acculturation, and the Summary of Diabetes Self Care Activities (SDSCA) questionnaire and Modified Insulin Management Diabetes Self Efficacy Scale (MIMDSES) were completed in English or Spanish. At one-month, 144 (84%) participants were available for follow-up by the research assistant masked to group assignment. ^ Results. At baseline, significant differences in foot self-care behaviors and self monitoring blood glucose were noted based on ethnicity and gender. Men had significantly lower confidence in their ability to manage their diabetes overall. There was a significant difference between baseline and follow up self reported foot self-care behaviors within the intervention group (t (47) = −4.32, p < .01) and the control group (t (46) = −2.06, p < .05). There were no significant differences between groups for self-reported foot self-care behaviors. There was a significant difference in observed foot self-care behaviors between groups (F(2,135) = 2.99, p < .05). Self-efficacy scores were positively correlated with self-reported self-care behaviors. ^ Conclusions. This predominantly Hispanic population with type 2 diabetes reported performing diabetes self-care behaviors less than five days a week. There were within group changes, but no significant between group changes in reported self-care behaviors. However, at the one month follow up, there were significant differences between groups in observed foot self-care behaviors with the intervention group demonstrating the most accurate behaviors. Differences based on gender and ethnicity emphasize the need to individualize diabetes education. Priorities for culturally competent diabetes education, approaches to increasing self-efficacy and future research directions are suggested. ^
