Improving disclosure of medical errors: Including patients and family members in the disclosure process

Over the last decade, adverse events and medical errors have become a main focus of interest for the standards of quality and safety in the U.S. healthcare system (Weinstein & Henderson, 2009). Particularly when a medical error occurs, the disclosure of medical errors and its practices have become a focal point of the healthcare process. Patients and family members who have experienced a medical error might be able to provide knowledge and insight on how to improve the disclose process. However, patient and family member are not typically involved in the disclosure process, thus their experiences go unnoticed. ^ The purpose of this research was to explore how best to include patients and family members in the disclosure process regarding a medical error. The research consisted of 28 qualitative interviews from three stakeholder groups: Hospital Administrators, Clinical Service Providers, and Patients and Family Members. They were asked for their ideas and suggestions on how best to include patients and family members in the disclosure process. Framework Analysis was used to analyze this data and find prevalent themes based on the primary research question. A secondary aim was to index categories created based on the interviews that were collected. Data was used from the Texas Disclosure and Compensation Study with Dr. Eric Thomas as the Principal Investigator. Full acknowledgement of access to this data is given to Dr. Thomas. ^ The themes from the research revealed that each stakeholder group was interested and open to including patients and family members in the disclosure process and that the disclosure process should not be a "one-way" avenue. The themes gave many suggestions regarding how to best include patients and family members in the disclosure process of a medical error. Secondary aims revealed several ways to assess the ideas and suggestion given by the stakeholders. Overall, acceptability of getting the perspective of patients and family members was the most common theme. Comparison of each stakeholder group revealed that including patients and family members would be beneficial to improving hospital disclosure practices. ^ Conclusions included a list of recommendations and measureable appropriate strategies that could provide hospital with key stakeholders insights on how to improve their disclosure process. Sharing patients and family members experience with healthcare providers can encourage a shift in culture where patients are valued and active in participating in hospital practices. To my knowledge, this research is the very first of its kind and moves the disclosure process conversation forward in a patient-family member inclusion direction that will assist in improving disclosure practices. Future research should implement and evaluate the success of the various inclusion strategies.^

Modulatory effects of bag cell peptides in {\it Aplysia}: Behavioral and electrophysiological studies

Reproductive hormones have effects on the nervous system not directly related to reproductive function. In the rat, for example, luteinizing hormone releasing hormone has dramatic effects on learning and memory. The present work attempts to examine the effects of reproductive hormones on non-reproductive behaviors and the neural loci and mechanisms underlying these effects in Aplysia, an animal whose behaviors, reproductive hormones and neural circuitry have been well characterized.^ In Aplysia, the neurosecretory bag cells release several peptides that are responsible for eliciting egg laying. The effects of these peptides on the defensive tail-siphon withdrawal reflex, as well as sensitization of this reflex, were examined. Sensitization, a simple form of nonassociative learning, refers to the behavioral enhancement of a response to a test stimulus after the presentation of a strong stimulus, that may last minutes (short-term) or days (long-term). An extract of the bag cells (BCE) inhibited the baseline siphon component of the tail-siphon withdrawal reflex and suppressed long-term, but not short-term, sensitization of the reflex. Preliminary experiments suggest that BCE also affects the tail component of the tail-siphon withdrawal reflex.^ To determine the neural mechanisms underlying the inhibition of the baseline reflex, electrophysiological studies were performed using an in vitro analogue of the tail-siphon withdrawal reflex to examine the ability of BCE, as well as the individual bag cell peptides (BCPs), to modulate the circuitry of the reflex. Bag cell extract attenuated the synaptic strength of the monosynaptic connections between tail sensory neurons and tail motor neurons. When individually applied only $\beta$-BCP produced a similar attenuation. This effect of $\beta$-BCP was not dependent on changes in duration of the presynaptic action potential.^ An in vitro analogue of long-term sensitization training was developed to examine the mechanisms by which the BCPs may affect long-term sensitization of the tail-siphon withdrawal reflex. This analogue exhibited both short- and long-term facilitation of the connections between the tail sensory and motor neurons.^ The results of these behavioral and electrophysiological experiments suggest that the BCPs inhibit the tail-siphon withdrawal reflex, at least in part, by modulating the synaptic strength of the connections between the sensory neurons and motor neurons underlying the reflex. One candidate for this effect is $\beta$-BCP. Thus, the peptides which elicit egg laying may also serve other functions such as the inhibition of defensive reflexes. In addition, these experiments raise the possibility that BCPs may exert a long lasting effect ($>$24 hr), suppressing long-term sensitization of the tail-siphon withdrawal reflex. ^

cDNA cloning and expression of a novel cell surface-expressed \b heparan sulfate/heparin \b interacting \b protein (HIP) from human cell lines and functional studies of a synthetic HIP peptide

Heparan sulfate proteoglycans and their corresponding binding sites have been suggested to play an important role during the initial attachment of blastocysts to uterine epithelium and human trophoblastic cell lines to uterine epithelial cell lines. Previous studies on RL95 cells, a human uterine epithelial cell line, characterized a single class of cell surface heparin/heparan sulfate (HP/HS)-binding sites. Three major HP/HS-binding peptide fragments were isolated from RL95 cell surfaces by tryptic digestion and partial amino-terminal amino acid sequence from each peptide fragment was obtained. In the current study, using the approaches of reverse transcription-polymerase chain reaction and cDNA library screening, a novel cell surface $\rm\underline{H}$P/HS $\rm\underline{i}$nteracting $\rm\underline{p}$rotein (HIP) has been isolated from RL95 cells. The full-length cDNA of HIP encodes a protein of 259 amino acids with a calculated molecular weight of 17,754 Da and pI of 11.75. Transfection of HIP cDNA into NIH-3T3 cells demonstrated cell surface expression and a size similar to that of HIP expressed by human cells. Predicted amino acid sequence indicates that HIP lacks a membrane spanning region and has no consensus sites for glycosylation. Northern blot analysis detected a single transcript of 1.3 kb in both total RNA and poly(A$\sp+$) RNA. Examination of human cell lines and normal tissues using both Northern blot and Western blot analysis revealed that HIP is differentially expressed in a variety of human cell lines and normal tissues, but absent in some cell lines examined. HIP has about 80% homology, at the level of both mRNA and protein, to a rodent protein, designated as ribosomal protein L29. Thus, members of the L29 family may be displayed on cell surfaces where they participate in HP/HS binding events. Studies on a synthetic peptide derived from HIP demonstrate that HIP peptide binds HS/HP with high selectivity and has high affinity (Kd = 10 nM) for a subset of polysaccharides found in commercial HIP preparations. Moreover, HIP peptide also binds certain forms of cell surface, but not secreted or intracellular. HS expressed by RL95 and JAR cells. This peptide supports the attachment of several human trophoblastic cell lines and a variety of mammalian adherent cell lines in a HS-dependent fashion. Furthermore, studies on the subset of HP specifically recognized by HIP peptide indicate that this high-affinity HP (HA-HP) has a larger median MW and a greater negative charge density than bulk HP. The minimum size of oligosaccharide required to bind to HIP peptide with high affinity is a septa- or octasaccharide. HA-HP also quantitatively binds to antithrombin-III (AT-III) with high affinity, indicating that HIP peptide and AT-III may recognize the same or similar oligosaccharide structure(s). Furthermore, HIP peptide antagonizes HP action and promotes blood coagulation in both factor Xa- and thrombin-dependent assays. Finally, HA-HP recognized by HP peptide is highly enriched with anticoagulant activity relative to bulk HP. Collectively, these results demonstrate that HIP may play a role in the HP/HS-involved cell-cell and cell-matrix interactions and recognizes a motif in HP similar or identical to that recognized by AT-III and therefore, may modulate blood coagulation. ^

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. ^

The identification of child abuse in Harris County in 1998

Characteristics of child abuse cases are not well known. In this study I collected data on 70 child abuse cases that were reported to Children's Protective Services in Harris County in 1998. The purpose of this study was to determine the factors in Harris County that lead to the identification of physical and sexual abuse. In order to answer the questions of who, what, where and when relative to the discovery of abuse I applied the same questionnaire (see Appendix) to each of 35 Sexual Abuse case reports and to each of 35 Physical Abuse/Neglect case reports. Answers to the first four questions were arranged by frequency distribution to show the predominant reporter, the 10 most common indicators, the most common locale, and the most frequent timing. Tables of the age, sex, and ethnicity of the children indicate the identity of those whose victimization was most reported. In addition the relationship between the form questions and the characteristics of the children was explored. A comparison of Sexual Abuse cases with Physical Abuse/Neglect cases was conducted and the results were analyzed and recorded in the Tables. ^ Child maltreatment often has negative short and long term effects on children's mental health and development. Suicide, violence, delinquency, drug and alcohol abuse and other forms of criminality are frequently child abuse related. Early detection and treatment helps to alleviate the myriad mental and physical ailments that untreated victims present as adults. This translates into medical dollar savings. ^ The long term objectives of my research were to reduce the number of undetected and unreported child abuse cases in Harris County by formulating better educational programs and literature for medical professionals and other personnel who are in contact with children. ^

Spirituality of Thai Buddhists with chronic cardiovascular disease

Background. Advances in medical technology contribute to the survival rate of a growing number of persons with chronic illnesses. Individuals with chronic cardiovascular disease (chronic CVD) are among other chronically ill persons who add to the need for healthcare services. They need to cope and live with the chronic conditions and find a new balance to make sense of their lives. Thai Buddhists with chronic CVD may use their religious resources to cope with their illnesses because religious beliefs are reflected in patterns of living. The aims of the study were to: (a) explore how Thai Buddhists with chronic CVD construct the spiritual aspects of the illness experience, (b) explore how Thai Buddhists with chronic CVD may use their spiritual/religious resources as a means of coping with the illness, and (c) explore the impacts of spiritual/religious beliefs and/or practices on the daily lives of Thai Buddhists with chronic CVD. ^ Methods. Ethnography was employed and data were collected from December 1, 2007 to May 31, 2008 using in-depth interviews with 20 participants. Field notes were also recorded. ^ Findings. Three categories emerged from the study data: set of spiritual and biomedical beliefs and practices, integrated meanings, and positive consequences of the integration of spiritual and biomedical beliefs and practices. ^ Conclusions. The findings of the study suggest the importance of understanding and integrating spiritual needs into care of patients with chronic CVD. The findings revealed that the participants constructed ideas of their illness and meanings for living and coping with the illness, and integrated spiritual and biomedical beliefs and practices, resulting in positive outcomes. Further research could test interventions which facilitate such coping; for example, using reflective thinking and group support. Other studies might explore how age affects Buddhist views of the illness. ^

A global perspective on intimate partner violence during pregnancy: An analysis of twelve developing countries

Violence against women has been recognized as a significant worldwide human rights issue and public health problem. Women of reproductive age may be particularly at risk, and pregnancy may trigger or escalate violence. Using data available from Demographic and Health Surveys on 271,103 women of reproductive age (15-49) from Bolivia, Cameroon, Colombia, Dominican Republic, Egypt, Haiti, India, Kenya, Nicaragua, Peru, South Africa, and Zambia, this study examined the nature of domestic violence during pregnancy in developing countries, including prevalence, demographic and risk factors, maternal and child health outcomes, perpetrators of violence, help-seeking behavior, and social support. In the majority of countries analyzed, violence during pregnancy consistently occurred at approximately one-third the rate at which domestic violence occurred overall. Younger women and women with more children were particularly at risk. Abuse during pregnancy was significantly associated with history of a terminated pregnancy and under-5 child mortality in most countries, and with neonatal and post-neonatal mortality in most Latin American countries. Women who were abused during pregnancy were most often abused by their current or former husband or boyfriend and most never attempted to seek help. In most countries that examined social support, women abused during pregnancy had significantly less contact with family and friends. Implications for practice and research are discussed. ^

Functional analysis of the Galpha protein, GNA -3, in the development of Neurospora crassa using biochemical and genetic studies

Extracellular signals regulate fungal development and, to sense and respond to these cues, fungi evolved signal transduction pathways similar to those in mammalian systems. In fungi, heterotrimeric G proteins, composed of α, β, and γ subunits, transduce many signals, such as pheromones and nutrients, intracellularly to alter adenylyl cyclase and MAPK cascades activity. ^ Previously, the Gα proteins GNA-1 and GNA-2 were characterized in regulating development in the fungus Neurospora crassa. R. A. Baasiri isolated a third Gα, gna-3, and P. S. Rowley generated Δgna-3 mutants. GNA-3 belongs to a fungal Gα family that regulates cAMP metabolism and virulence. The Δ gna-3 sexual cycle is defective in homozygous crosses, producing inviable spores. Δgna-3 mutants have reduced aerial hyphae formation and derepressed asexual sporulation (conidiation), causing accumulation of asexual spores (conidia). These defects are similar to an adenylyl cyclase mutant, cr-1; cAMP supplementation suppressed Δ gna-3 and cr-1. Inappropriate conidiation and expression of a conidiation gene, con-10, were higher in Δ gna-3 than cr-1 submerged cultures; peptone suppressed conidiation. Adenylyl cyclase activity and expression demonstrated that GNA-3 regulates enzyme levels. ^ A Δgna-1 cr-1 was analyzed with F. D. Ivey to differentiate GNA-1 roles in cAMP-dependent and -independent pathways. Δ gna-1 cr-1 defects were worse than cr-1 and refractory to cAMP, suggesting that GNA-1 is necessary for sensing extracellular CAMP. Submerged culture conidiation was highest in Δgna-1 cr-1, and only high cell density Δgna-1 cultures conidiated, which correlated with con-10 levels. Transcription of a putative heat shock cognate protein was highest in Δgna-1 cr-1. ^ Functional relationships between the three Gαs was analyzed by constructing Δgna-1 Δgna-2 Δ gna-3, Δgna-1 Δgna-3, and Δgna-2 Δgna-3 strains. Δ gna-2 Δgna-3 strains exhibited intensified Δ gna-3 phenotypes; Δgna-1 Δgna-2 Δgna-3 and Δgna-1 Δ gna-3 strains were identical to Δgna-1 cr-1 on plates and were non-responsive to cAMP. The highest levels of conidiation and con-10 were detected in submerged cultures of Δ gna-1 Δgna-2 Δgna-3 and Δgna-1 Δgna-3 mutants, which was partially suppressed by peptone supplementation. Stimulation of adenylyl cyclase is completely deficient in Δgna-1 Δ gna-2 Δgna-3 and Δgna-1 Δ gna-3 strains. Δgna-3 and Δ gna-1 Δgna-3 aerial hyphae and conidiation defects were suppressed by mutation of a PKA regulatory subunit. ^
