Effect of Eliminating Seropositive Canines on the Transmission of Visceral Leishmaniasis in Brazil

In Brazil, where Leishmania chagasi causes endemic American visceral leishmaniasis (AVL), the spread and maintenance of human disease are attributed to canine reservoirs. However, despite measures directed toward the elimination of infected canines, the incidence of human disease continues to increase. To evaluate the role of infected canines in the acquisition of AVL by humans, we undertook a controlled intervention study in three similar, but isolated, valleys of Pancas, Espírito Santo, Brazil. In the two experimental (intervention) valleys, infected dogs were eliminated whereas in the control valley, seropositive canines remained untouched. During the 12-month study period, human seropositivity rates, as measured by dot enzyme-linked immunosorbent assay, increased from 15% to 54% in the intervention valleys and from 14% to 54% in the control valley. The elimination of infected canines in the intervention valleys did not result in a statistically significant difference between the incidences of human serological conversion in the intervention and control valleys at either 6 (20% and 22%, respectively; P = .5961) or 12 months (26% and 27%, respectively; P = .9442). The role of humans as a significant reservoir for AVL is proposed as an explanation for the study results.

Parental Views on Withdrawing Life-Sustaining Therapies in Critically Ill Children

OBJECTIVE To broaden existing knowledge of pediatric end-of-life decision making by exploring factors described by parents of patients in the pediatric intensive care unit (PICU) as important/influential if they were to consider withdrawing life-sustaining therapies. DESIGN Quantitative and qualitative analysis of semi-structured one-on-one interviews. SETTING The PICUs at 2 tertiary care hospitals. PARTICIPANTS English- or Spanish-speaking parents who were older than 17 years and whose child was admitted to the PICU for more than 24 hours to up to 1 week. INTERVENTION Semi-structured one-on-one interviews. RESULTS Forty of 70 parents (57%) interviewed said they could imagine a situation in which they would consider withdrawing life-sustaining therapies. When asked if specific factors might influence their decision making, 64% of parents said they would consider withdrawing life-sustaining therapies if their child were suffering; 51% would make such a decision based on quality-of-life considerations; 43% acknowledged the influence of physician-estimated prognosis in their decision; and 7% said financial burden would affect their consideration. Qualitative analysis of their subsequent comments identified 9 factors influential to parents when considering withdrawing life-sustaining therapies: quality of life, suffering, ineffective treatments, faith, time, financial considerations, general rejection of withdrawing life-sustaining therapies, mistrust/doubt toward physicians, and reliance on self/intuition. CONCLUSION Parents describe a broad range of views regarding possible consideration of withdrawing life-sustaining therapies for their children and what factors might influence such a decision.

End-of-life care decisions in the PICU: roles professionals play.

Objective: Describe the roles and respective responsibilities of PICU healthcare professionals in end-of-life care decisions faced by PICU parents. Design: Retrospective qualitative study. Setting: University-based tertiary care children’s hospital. Participants: Eighteen parents of children who died in the pediatric ICU and 48 PICU healthcare professionals (physicians, nurses, social workers, child-life specialists, chaplains, and case managers). Interventions: In depth, semi-structured focus groups and one-on-one interviews designed to explore experiences in end-of-life care decision making. Measurements and Main Results: We identified end-of-life care decisions that parents face based on descriptions by parents and healthcare professionals. Participants described medical and nonmedical decisions addressed toward the end of a child’s life. From the descriptions, we identified seven roles healthcare professionals play in end-of-life care decisions. The family supporter addresses emotional, spiritual, environmental, relational, and informational family needs in a nondirective way. The family advocate helps families articulate their views and needs to healthcare professionals. The information giver provides parents with medical information, identifies decisions or describes available options, and clarifies parents’ understanding. The general care coordinator helps facilitate interactions among healthcare professionals in the PICU, among healthcare professionals from different subspecialty teams, and between healthcare professionals and parents. The decision maker makes or directly influences the defined plan of action. The end-of-life care coordinator organizes and executes functions occurring directly before, during, and after dying/death. The point person develops a unique trusting relationship with parents. Conclusions: Our results describe a framework for healthcare professionals’ roles in parental end-of-life care decision making in the pediatric ICU that includes directive, value-neutral, and organizational roles. More research is needed to validate these roles. Actively ensuring attention to these roles during the decision-making process could improve parents’ experiences at the end of a child’s life.

Chlamydia trachomatis infection in a rural population: the importance of screening men

This prospective observational cohort study describes the demographics, risk of re-infection, and geographical distribution of chlamydia infections in a rural North Carolina county. Data were collected between 1 November 1992 and 21 January 1994 from private physician reports and from screening patients at the county health department STD clinic. The overall chlamydia rate in the county was 563 cases per 100,000 person-years. Rates were highest among women, 15-19-year-olds and non-whites (662, 3982 and 1272 cases per 100,000 person-years, respectively). The 6-month cumulative incidence of re-infection was 10%. Geographic mapping of case rates showed contiguity among high-risk block groups. The rate in men, 449 cases per 100,000 person-years, was higher than expected. Issues concerning the development of screening programmes for men are discussed.

The Bereaved Parent Needs Assessment: A new instrument to assess the needs of parents whose children died in the pediatric intensive care unit

Objectives:To evaluate the reliability and validity of the Bereaved Parent Needs Assessment, a new instrument to measure parents’ needs and need fulfillment around the time of their child’s death in the pediatric intensive care unit. We hypothesized that need fulfillment would be negatively related to complicated grief and positively related to quality of life during bereavement. Design:Cross-sectional survey. Setting:Five U.S. children’s hospital pediatric intensive care units. Subjects:Parents (n = 121) bereaved in a pediatric intensive care unit 6 months earlier. Interventions:Surveys included the 68-item Bereaved Parent Needs Assessment, the Inventory of Complicated Grief, and the abbreviated version of the World Health Organization Quality of Life questionnaire. Each Bereaved Parent Needs Assessment item described a potential need and was rated on two scales: 1) a 5-point rating of importance (1 = not at all important, 5 = very important) and 2) a 5-point rating of fulfillment (1 = not at all met, 5 = completely met). Three composite scales were computed: 1) total importance (percentage of all needs rated ≥4 for importance), 2) total fulfillment (percentage of all needs rated ≥4 for fulfillment), and 3) percent fulfillment (percentage of important needs that were fulfilled). Internal consistency reliability was assessed by Cronbach’s &agr; and Spearman-Brown–corrected split-half reliability. Generalized estimating equations were used to test predictions between composite scales and the Inventory of Complicated Grief and World Health Organization Quality of Life questionnaire. Measurements and Main Results:Two items had mean importance ratings <3, and 55 had mean ratings >4. Reliability of composite scores ranged from 0.92 to 0.94. Total fulfillment was negatively correlated with Inventory of Complicated Grief (r = −.29; p < .01) and positively correlated with World Health Organization Quality of Life questionnaire (r = .21; p < .05). Percent fulfillment was also significantly correlated with both outcomes. Adjusting for parent’s age, education, and loss of an only child, percent fulfillment remained significantly correlated with Inventory of Complicated Grief but not with World Health Organization Quality of Life questionnaire. Conclusions:The Bereaved Parent Needs Assessment demonstrated reliability and validity to assess the needs of parents bereaved in the pediatric intensive care unit. Meeting parents’ needs around the time of their child’s death may promote adjustment to loss.

The Use of Family Conferences in the Pediatric Intensive Care Unit

BACKGROUND Data about pediatric intensive care unit (PICU) family conferences (FCs) are needed to enhance our understanding of the role of FCs in patient care and build a foundation for future research on PICU communication and decision making. OBJECTIVE The studys objective was to describe the use and content of PICU FCs. DESIGN The study design was a prospective chart review comparing patients who had conferences with those who did not, and a sub-analysis of patients with chronic care conditions (CCCs). SETTING/SUBJECTS The study setting was an academic PICU from January 2011 through June 2011. MEASUREMENTS Medical events under consideration were placement of tracheostomy or gastrostomy tube; initiation of chronic ventilation; palliative care involvement; use of extracorporeal membrane oxygenation, continuous renal replacement, or cardiopulmonary resuscitation; care limitation orders; death; length of stay; and discharge to a new environment. RESULTS From 661 admissions, we identified 74 conferences involving 49 patients. Sixty-four conferences (86%) were held about 40 patients with CCCs. Having a conference was associated with (p<0.05): length of PICU admission; palliative care involvement; initiation of chronic ventilation; extracorporeal membrane oxygenation; cardiopulmonary resuscitation; death; discharge to a new environment; and care limitation orders. Twenty-nine percent of patients who had a new tracheostomy or gastrostomy tube placed had a conference. We identified two categories of discussion topics: information exchange and future management. CONCLUSIONS Most identified FCs involved complex patients or patients who faced decisions affecting the childs quality of life or dying. For many patients who faced life changing decisions we did not identify a FC. Further research is needed to understand how to best utilize FCs and less formal conversations.

Communication During Pediatric Intensive Care Unit Family Conferences: A Pilot Study of Content, Communication, and Parent Perceptions

ABSTRACT While there is a robust literature describing family conferences (FCs) in adult intensive care units (ICUs), less information exists about FCs in pediatric ICUs (PICUs). We conducted a pilot study to describe the focus of discussion, communication patterns of health care team members (HTMs) and parents, and parents’ perspectives about clinician communication during PICU FCs. We analyzed data from 22 video- or audiorecorded PICU FCs and post-FC questionnaire responses from 27 parents involved in 18 FCs. We used the Roter Interaction Analysis System (RIAS) to describe FC dialogue content. Our questionnaire included the validated Communication Assessment Tool (CAT). FCs were focused on care planning (n = 5), decision making (n = 6), and updates (n = 11). Most speech came from HTMs (mean 85%; range, 65–94%). Most HTM utterances involved medical information. Most parent utterances involved asking for explanations. The mean overall CAT score was 4.62 (using a 1–5 scale where 5 represents excellent and 1 poor) with a mean of 73.02% “excellent” responses. Update and care-planning FCs had lower CAT scores compared to decision-making FCs. The lowest scoring CAT items were “Involved me in decisions as much as I wanted,” “Talked in terms I could understand,” and “Gave me as much information as I wanted.” These findings suggest that while health care providers spend most of their time during FCs relaying medical information, more attention should be directed at providing information in an understandable manner. More work is needed to improve communication when decision making is not the main focus of the FC.

Provider Perspectives on Use of Medical Marijuana in Children With Cancer

As more states legalize MM, we explore provider practices, knowledge, attitudes, and barriers regarding legal MM use in children with cancer. BACKGROUND: Although medical marijuana (MM) may have utility in the supportive care of children with serious illness, it remains controversial. We investigated interdisciplinary provider perspectives on legal MM use in children with cancer. METHODS: We sent a 32-item, cross-sectional survey to 654 pediatric oncology providers in Illinois, Massachusetts, and Washington characterizing MM practices, knowledge, attitudes, and barriers. Forty-eight percent responded; 44% (n = 288) were included in analyses. Providers were stratified by status as legally eligible to certify (ETC) for MM. We used Fisher’s exact and Wilcoxon rank tests and univariate and multivariate logistic regression models for group comparisons. RESULTS: The provider median age was 35 years (range 22–70 years); 33% were ETC (83 physicians; 13 Washington state advance practice providers). Thirty percent of providers received ≥1 request for MM in the previous month. Notably, only 5% of all providers knew state-specific regulations. ETC providers were more likely to know that MM is against federal laws (P < .0001). Whereas most providers (92%) reported willingness to help children with cancer access MM, in adjusted models, ETC providers were less likely to indicate approval of patient MM use by smoking, oral formulations, as cancer-directed therapy, or to manage symptoms (P < .005 for all). Forty-six percent of all providers cited the absence of standards around formulations, potency, or dosing to be the greatest barrier to recommending MM. CONCLUSIONS: Most pediatric oncology providers are willing to consider MM use in children with cancer and receive frequent inquiries. However, ETC providers endorse less favorable attitudes overall. The absence of standards is an important barrier to recommending MM.

Variations in Criteria and Practices for Heart Transplantation Listing Among Pediatric Transplant Cardiologists

Ethical issues in pediatric heart transplantation (Htx) include resource allocation, benefit, and burden assessment in high-risk recipients, and informed consent. Practice patterns and decision-making was investigated using an internet survey with 47-multiple choice items and vignette-based questions. Of 43 pediatric Htx cardiologists contacted, 28 (65%) responded. Respondents reported that an overall median 1-month survival of 73% (range 50–100%), 1-year survival of 70% (range 50–85%), 5-year survival of 50% (range 40–85%), and 10-year survival of 50% (range 25–85%) was adequate to offer Htx. Based on vignettes presented, 100% of those surveyed would offer Htx to a straightforward 12-year old with end-stage dilated cardiomyopathy and a 7-year old with hypoplastic left heart syndrome with protein losing enteropathy. Thirty percent of physicians would offer Htx to a patient status post a Fontan procedure with mutliple co-morbidities. Seventy-five percent of physicians would offer Htx despite proven non-adherence. Considerable variability exists in the practice patterns of pediatric heart transplant cardiologists with regards to decision-making while evaluating patients for listing. Disagreements among pediatric Htx cardiologists exist when there are concerns for non-adherence and associated multiple co-morbidities. Further work is needed to understand these variations and develop consensus for pediatric Htx organ allocation.

Biobanking in the Pediatric Critical Care Setting: Adolescent/Young Adult Perspectives

Biorepository research in children raises numerous ethical questions that are heightened in the pediatric intensive care unit (PICU) setting. We conducted a cross-sectional, interview-based study of 20 adolescent/young adult (A/YA) PICU patients and 75 parents of PICU patients to elucidate perspectives on biorepository research. A/YAs had a positive attitude toward biobanking. In young adults, comprehension was higher for knowledge of a choice to withdraw and participate in the research and lower for purpose, procedures, risks, and benefits of participation. All but one A/YA wanted to have a say in whether their samples would be used. Parent views on child assent were mixed; 55% of parents favored child involvement in decisions. Efforts should be made to improve comprehension by A/YAs and involvement of A/YAs in decisions.
