Healthcare provider perspectives on parental refusal of medical interventions: A qualitative study

Background. Healthcare providers in pediatrics are faced with parents making medical decisions for their children. Refusal to consent to interventions can have life threatening sequelae, yet healthcare workers are provided little training in handling refusals. The healthcare provider's experience in parental refusal has not been well described, yet is an important first step in addressing this problem. ^ Specific aims. Describe: (1) the decision-making processes made by healthcare providers when parents refuse medical interventions for their children, (2) the source of healthcare workers' skills in handling situations of refusal, and (3) the perspectives of healthcare workers on parental refusals in the inpatient setting. ^ Methods. Nurses, physicians and respiratory therapists (RT) were recruited via e-mail at Texas Children's Hospital (TCH). Interview questions were developed using Social Cognitive Theory constructs and validated. One-on-one in-depth, one hour semi-structured interviews were held at TCH, audio recorded and transcribed. Coding and analysis were done using ATLAS ti. The constant comparative method was applied to describe emergent themes that were reviewed by an independent expert. ^ Results. Interviews have been conducted with nurses (n=6), physicians and practitioners (n=6), social workers (n=3) and RT (n=3) comprising 13 females and 5 males with 3–25 years of experience. Decision-making processes relate to the experience of the caregiver, familiarity with the family, and the acuity of the patient. Healthcare workers' skills were obtained through orientation processes or by trial-and-error. Themes emerged that related to the importance of: (1) Communication, where the initial discussion about a medical procedure should be done with clarity and an understanding of the parents' views; (2) Perceived loss of control by parents, a key factor in their refusal of interventions; and (3) Training, the need for skill development to handle refusals. ^ Conclusions. Effective training involving clarity in communication and a preservation of perceived control by parents is needed to avoid the current trial-and-error experience of healthcare workers in negotiating refusal situations. Such training could lessen the more serious outcomes of parental refusal. ^

Changing Tides and Changing Focus: Mapping the Challenges and Successes of One State's Implementation Of the Adoption and Safe Families Act of 1997

In 1997, the Adoption and Safe Families Act shifted from the preservation of families to an emphasis on safety, permanency, and well-being through expediting the termination of parental rights, establishing exceptions to the reasonable efforts clause of preserving the family, and fiscal incentives for finalizing adoptions. The current project assessed the role of a full service array in achieving the outcomes set forth in ASF A. Concept mapping was utilized to elicit information from participants (both urban and rural) regarding the identified research question. Participants recognized family preservation versus safety, community connections, mandates versus reality, and worker recruitment and retention as critical components for meeting ASFA goals. Perceived importance and level of success in implementing these services was also highlighted. Recommendations supported through the data are also provided.

The cDNA cloning of murine HIP /L29 and the functional analysis of HIP/L29 domains

Human heparin/heparan sulfate interacting protein/L29 (HIP/L29) is a heparin/heparan sulfate (Hp/HS) binding protein found in many adult human tissues. Potential functions of this protein are promotion of embryo adhesion, modulation of blood coagulation, and control of cell growth. While these activities are diverse, the ability of human HIP/L29 to interact with Hp/HS at the cell surface may be a unifying mechanism of action since Hp/HS influences all of these processes. A murine ortholog has been identified that has 78.8% homology over the entire sequence and identity over the N-terminal 64 amino acids when compared to human HIP/L29. Northern, Western, and immunohistochemical analysis shows that murine HIP/L29 mRNA and protein are expressed in a tissue specific manner. Murine HIP/L29 is enriched in the membrane fraction of NmuMG cells where it is eluted with high salt, suggesting that it is a peripheral membrane protein. The ability of murine HIP/L29 to bind Hp is verified by studies using native and recombinant forms of murine HIP/L29. A synthetic peptide (HIP peptide-2) derived from the identical N-terminal region of HIP/L29 proteins was tested for the ability to bind Hp and support cell adhesion. This peptide was chosen because it conforms to a proposed consensus sequence for Hp/HS binding peptides. HIP peptide-2 binds Hp in a dose-dependent, saturable, and selective manner and supports Hp-dependent cell adhesion. However, a scrambled form of this peptide displayed similar activities indicating a lack of peptide sequence specificity required for activity. Lastly, an unbiased approach was used to identify sequences within human and mouse HIP/L29 proteins necessary for Hp/HS binding. A panel of recombinant proteins was made that collectively are deficient in every human HIP/L29 domain. The activities of these deletion mutants and recombinant murine HIP/L29 were compared to the activity of recombinant human HIP/L29 in a number of assays designed to look at differences in the ability to bind Hp/HS. These studies suggest that each domain within human HIP/L29 is important for binding to Hp/HS and divergences in the C-terminus of human and mouse HIP/L29 account for a decrease in murine HIP/L29 affinity for Hp/HS. It is apparent that multiple domains within human and mouse HIP/L29 contribute to the function of Hp/HS binding. The interaction of multiple HIP/L29 domains with Hp/HS will influence the biological activity of HIP/L29 proteins. ^
