Abstract

Reducing sex risk behaviors among high-risk injection drug users (IDUs) and crack smokers is a continuing challenge for HIV prevention. Based on a longitudinal study of sexually active Puerto Rican IDUs and crack smokers in New York (n=573) and Puerto Rico (n=264), baseline predictors of changes in sex risk (number of unprotected sex acts) at 6- and 36-month follow-up interviews were examined. In New York, predictors of higher sex risk were being younger, having primary partners, having more other sex partners, never exchanging sex, having lower self-efficacy for reducing sex risk behaviors and being HIV-negative, and these predictors were significant at both postbaseline periods. In Puerto Rico, short-term predictors included being male, having primary partners, never exchanging sex, lower sex risk norms and lower self-efficacy. However, only having primary partners was significant in longer-term behaviors. Results indicated the need for enhancing self-efficacy and for developing risk reduction strategies related to community differences.

Abstract

Objective. To analyze corporate governance arrangements and quality and financial performance outcomes among large multi-facility nursing home corporations (chains) that pursue stakeholder value (profit maximization) strategies. Study Design. To establish a foundation of knowledge about the focal phenomenon and processes, we conducted an historical (1993-2005) case study of one of the largest chains (Sun Helathcare Inc.) that triangulated qualitative and quantitative data sources. Data Sources. Two main sets of information were compared: (1) corporate sources including Sun's Security Exchange Commission (SEC) Form 10-K annual reports, industry financial reports, and the business press; and (2) external sources including, legal documents, press reports, and publicly available California facility cost reports and quality data. Principal Findings. Shareholder value was pursued at Sun through three inter-linked strategies: (1) rapid growth through debt-financed mergers; (2) labor cost constraint through low nurse staffing levels; and (3) a model of corporate governance that views sanctions for fraud and poor quality as a cost of business. Conclusions. Study findings and evidence from other large nursing home chains underscore calls from the Institute of Medicine and other bodies for extended oversight of the corporate governance and performance of large nursing home chains.

Abstract

Objective: To identify processes affecting agency for safety among perinatal nurses, physicians, and certified nurse-midwives. Design: Grounded theory, as informed by Strauss and Schatzman. Setting: Two academic perinatal units in the western United States. Participants: Purposive sample of 12 registered nurses, 5 physicians, and 2 certified nurse-midwives. Findings: Agency for safety (the willingness to take a stand on an issue of concern) fluctuated for all types of providers depending on situational context and was strongly influenced by interpersonal relationships. While physicians and certified nurse-midwives believed that they valued nurses' contributions to care, their units had deeply embedded hierarchies. Nurses were structurally excluded from important sources of information exchange and from contributing to the plan of care. Nurses'confidence was a key driver for asserting their concerns. Confidence was undermined in novel or ambiguous situations and by poor interpersonal relationships, resulting in a process of redefining the situation as a problem of self. Conclusions: Women and babies should not be dependent on the interpersonal relationships of providers for their safety. Clinicians should be aware of the complex social pressures that can affect clinical decision making. Continued research is needed to fully articulate facilitators and barriers to perinatal safety.

Abstract

The association between socioeconomic status (SES) and current regular alcohol use was examined separately for urban and rural residents of Hubei, China, using the third Chinese National Health Service Survey conducted in 2003. A probability sample of 15,609 respondents, ages 15 through 101 years, was selected from the study base. Alcohol use was a dichotomized variable (current regular users vs. others). Multivariate analyses incorporated four SES indicators: income, education, occupation, and house size. Investigation of status discrepancy indicated that income was positively associated with the likelihood of current regular alcohol use, whereas education was negatively associated. For both urban and rural residents, likelihood of current regular alcohol use was smallest for those in the highest education and lowest income category. Further research, which factors in quantity and frequency, is needed to understand how alcohol use among Chinese urban and rural populations impacts their health.

Abstract

Objective: To explore the practice of midwifery within a busy urban tertiary hospital birth setting and to present findings on the relationships between nurses and midwives in providing maternity care. Design/Method: A focused ethnography on midwifery practice conducted over 2 years (2004-2006) in a teaching hospital serving a primarily Medicaid-eligible population in Northern California. Data were collected through participant observations and in-depth interviews with midwives (N = 11) and nurses (N = 14). Practices and relationships among the midwives and nurses were examined in an ethnographic framework through thematic analysis. Findings: Two themes described the nature of nursing-midwifery relationships: tension and teamwork. Tension existed in philosophic approaches to care, definitions of safe practice, communication, and respect. Teamwork existed when the midwives and nurses worked in partnership with the woman to develop a plan of care. Changes were brought about to improve the midwife-nurse relationship during the conduct of the study. Conclusions: Midwives and nurses experienced day-to-day challenges in providing optimal care for childbearing women. The power of effective teamwork was profound, as was the tension when communication broke down. Failure to include nurses resulted in impaired translation of evidence into practice. All stakeholders in birth practices and policy development must be involved in future research in order to develop effective maternity care models.

Abstract

Background. The hepatitis C virus (HCV) is hyper-endemic in injecting drug users. There is also excess HCV among non-injection drug users who smoke, snort, or sniff heroin, cocaine, crack, or methamphetamine. Methods. To summarize the research literature on HCV in drug users and identify gaps in knowledge, we conducted a synthesis of the relevant research carried out between 1989 and 2006. Using rigorous search methods, we identified and extracted data from published and unpublished reports of HCV among drug users. We designed a quality assurance system to ensure accuracy and consistency in all phases of the project. We also created a set of items to assess study design quality in each of the reports we included. Results. We identified 629 reports containing HCV prevalence rates, incidence rates and/or genotype distribution among injecting or non-injecting drug user populations published between January 1989 and December 2006. The majority of reports were from Western Europe (41%), North America (26%), Asia (11%) and Australia/New Zealand (10%). We also identified reports from Eastern Europe, South America, the Middle East, and the Caribbean. The number of publications reporting HCV rates in drug users increased dramatically between 1989 and 2006 to 27-52 reports per year after 1998. Conclusion. The data collection and quality assurance phases of the HCV Synthesis Project have been completed. Recommendations for future research on HCV in drug users have come out of our data collection phase. Future research reports can enhance their contributions to our understanding of HCV etiology by clearly defining their drug user participants with respect to type of drug and route of administration. Further, the use of standard reporting methods for risk factors would enable data to be combined across a larger set of studies; this is especially important for HCV seroconversion studies which suffer from small sample sizes and low power to examine risk factors.

Whether it's already touching your facility or its impact is still to come, this crisis will test your skills as a manager. Understanding what's driving the shortage and what's predicted will help you choose the best strategies for addressing its causes and dealing with its consequences.

Abstract

This article describes the role of a committee in the Graduate School of Nursing at the University of Massachusetts, Worcester, that is referred to as the research advisory committee. It was developed to sustain the research mission, to facilitate faculty scholarship, and to provide a venue for presubmission grant review (hence called mock review) in a graduate school of nursing that is not considered "research intensive." We present its historical framework, the development of a mock review process, faculty accomplishments thus far, and our plans for the future. It is hoped that our experiences of building and supporting faculty research efforts in a research dynamic environment may provide guidance for others working in similar institutions.

Abstract

There is a real danger that measurable tasks and procedures can be misconstrued for nursing practice in contemporary healthcare organizations focused on the measurement of quality, safety, and productivity. This study uses the work of Patricia Benner to address the complex nature of nursing practice and discusses why the chief nursing officer must create an environment within the organization for the practice to be fully lived out if he or she is to be successful as the leader of the discipline.

Abstract

The aims of this replication study were to determine if subgroups of oncology outpatients receiving active treatment could be identified based on their experience with the symptoms of fatigue, sleep disturbance, depression, and pain; whether patients in these subgroups differed on selected demographic, disease, and treatment characteristics; and if patients in these subgroups differed on functional status and quality of life (QOL). A convenience sample of 228 oncology outpatients was recruited from seven outpatient settings in Israel. Patients completed a demographic questionnaire, a Karnofsky Performance Status score, the Multidimensional Quality of Life Scale-Cancer, the Lee Fatigue Scale, the General Sleep Disturbance Scale, the Center for Epidemiological Studies-Depression Scale, and a numeric rating scale of worst pain intensity. Cluster analysis was used to identify the patient subgroups based on their symptom experience. Four relatively distinct patient subgroups were identified based on their experiences with the above symptoms (i.e., low levels of all four symptoms (32.9%), low levels of pain and high levels of fatigue (18.0%), high levels of pain and moderate levels of fatigue (42.5%), and high levels of all four symptoms (6.6%). No differences were found among the four subgroups on any demographic, disease, or treatment characteristics. The subgroup of patients who reported high levels of all four symptoms reported the worst functional status and poorest QOL. In conclusion, differences in the symptom experience of oncology outpatients suggest that patients may harbor different phenotypic characteristics (e.g., environmental or physiologic) or genetic determinants for experiencing symptoms that are independent of demographic, disease, and treatment characteristics.

Abstract

Fatigue is the most common and distressing symptom reported by patients undergoing radiation therapy (RT). However, limited information is available on the trajectories of fatigue, as well as on the predictors of interindividual variability in fatigue. This study evaluated a sample of patients who underwent RT for prostate cancer to examine how ratings of evening and morning fatigue changed from the time of simulation to four months after the completion of RT and to investigate whether specific patient, disease, and symptom characteristics predicted the initial levels of fatigue and/or characteristics of the trajectories of evening and morning fatigue. Using hierarchical linear modeling, a large amount of interindividual variability was demonstrated in the trajectories of evening and morning fatigue. Findings from this study suggest that younger men with a higher level of fatigue at the time of the simulation visit were at increased risk for higher levels of evening and morning fatigue over the course of RT. In addition, the level of morning fatigue over the course of RT appears to depend on the patient's level of depression at the time of the simulation visit. In future studies, the use of hierarchical linear modeling as an analytic tool will assist in the identification of patients who are most at risk for prolonged fatigue trajectories. This type of analysis may lead to the identification of subgroups of patients who are at higher risk for negative outcomes and who require different types of interventions for the fatigue associated with RT.

Abstract

Colecta-PALM is a Web-based application delivered on PDAs that provides behavioral messaging based on risk assessment responses for HIV patients. Usability testing was undertaken with 15 people living with HIV.AIDS (PWLHA) in two clinics in Lima. Sixty percent (9/15) were somewhat/very satisfied with Colecta-PALM, with usefulness rated 3.7/5. Users found the tool innovative, interesting, easy to use, educational, trustworthy, private, and non-judgmental. Colecta-PALM was well-received and easily usable by most.

Abstract

Congenital heart defects (CHDs) are the most common of all birth defects. For many newborns with a CHD, prenatal versus postnatal detection is associated with substantially decreased morbidity and mortality risks. Although technological advances in fetal echocardiography have led to an increased capacity to detect CHDs prenatally, pregnancies without an identified risk factor are not routinely screened. With the aim of identifying pregnancies at increased risk for CHDs, this study examined the relationship between CHDs and typically collected second trimester biomarker data collected on a large population-based sample of singleton pregnancies with one or more second trimester screen positive result for Down syndrome, trisomy 18 (T-18), Smith-Lemli-Opitz syndrome (SLOS), or a neural tube defect (NTD). Where possible, logistic models for cases and controls were built and potential referral models were tested among study subsamples with information on the presence or absence of CHDs reported pre- and perinatally. When considered in combination, screen positive for T-18, screen positive for SLOS, nuchal fold measurement ≥ 5 mm, and/or having an adjusted hCG multiple of the median ≥ the 95th centile detected 42.7% of all pregnancies with a CHD in the combined subsample (where co-occurrence with chromosomal defects was not considered) and detected 29.7% of all pregnancies with a CHD in the no-chromosomal defect subsample. A nuchal fold measurement ≥ 5 mm detected 18.2% of those with a CHD in the Down syndrome subsample and an adjusted hCG multiple of the median (MoM) ≤ 5th centile detected 92.9% of those with a CHD in the T-18 subsample.

Abstract

Violence against women is a major public health concern. This paper describes an educational strategy to increase nursing students' understanding of the experience of violence and to foster recognition and intervention with victims of violence. Students in an elective course were asked to critically reflect on the personal stories of victims/survivors of violence. The assignment provided four learning opportunities that include examination of societal myths on sexual victimization, understanding the lived experience of the victim, exploration of personal beliefs and values, and the relationship of the individual's experience to theoretical content of the course. Students gave permission for the use of quotes from papers to illustrate the learning opportunities.
