Factors Affecting Adolescents' Willingness to Communicate Symptoms During Cancer Treatment: A Systematic Review from the Children's Oncology Group.

The purpose of this systematic review is to (1) synthesize evidence facilitators and barriers affecting adolescent willingness to communicate symptoms to health care providers (HCPs) and (2) create practice recommendations. The PICOT (Population, Intervention, Comparison, Outcome, Time) question guiding the review was, among adolescents with cancer, what factors affect their willingness to communicate symptoms to HCPs? Three databases, PubMed, CINAHL, and PsychINFO, were searched using keywords from the PICOT question. Inclusion criteria included original research studies with samples of at least 51% adolescents aged 10-18 years who were receiving or had received cancer treatment. Studies were included that evaluated outcomes related to willingness to communicate in general as well as communication of specific treatment symptoms. Exclusion criteria included systematic reviews and publications emphasizing cancer screening, cancer prevention, survivorship, or decision making. A total of 11 studies were included in the systematic review. Two of the studies focused on symptom communication; the remaining nine studies focused on general communication or the overlap between general and symptom communication. Barriers to symptom and/or general communication included negative expectations, health-related uncertainty, ambiguousness with assessments, unfamiliarity, restriction of information, perceived negative provider characteristics/behaviors, adolescent circumstance, worry about others' perceptions, and provider approach. Facilitators to symptom and/or general communication included open communication, perceived favorable provider characteristics/behaviors, seasoned adolescent, and patient-provider rapport. Five practice recommendations were developed from the evidence that supports general and symptom communication between adolescents who are receiving or have completed cancer treatment and their HCPs.

Interrater reliability of the Supports Intensity Scale (SIS).

The interrater reliability of the Supports Intensity Scale (SIS) was investigated under the condition that interviewers had to have been trained and/or experienced in its administration and scoring. Both corrected and noncorrected Pearson's product-moment coefficients were generated to assess interinterviewer, interrespondent, and mixed interrater reliability. The correlation coefficients for the SIS Support Needs Index Score and SIS subscale scores were considerably higher than coefficients reported in the SIS Users Manual that were derived from a similar study conducted with untrained, inexperienced interviewers.

Standardization of health care provider competencies for intrathecal access procedures.

INTRODUCTION: This quality improvement (QI) project addresses a method for experienced health care providers to maintain skill-based competence for intrathecal access procedures. METHODS: A prospective QI design using intrathecal access simulation to assess, educate, and evaluate skill competency. Simulation was used as a strategy to promote patient safety and standardize practice patterns. Pretest and posttest methodology using paired t tests were performed to assess anxiety, confidence, and knowledge. RESULTS: Fourteen pediatric providers participated in this QI project. There was a statistically significant improvement in confidence measuring intracranial pressure (ICP; t = -2.92, P = .013), performance-related overall anxiety (t = -2.132, P = .05) and administering intrathecal chemotherapy (t = -2.144, P = .053). Fifty percent of participants missed a medication error demonstrating confirmation bias. CONCLUSION: This simulation strategy resulted in improved confidence in measuring ICP, performance-related overall anxiety, and confidence in administering chemotherapy. Confirmation bias occurred during simulation testing for a medication error. We propose this method for maintaining clinical competencies in health care providers and introducing new skills to existing practices.

Incidence and patterns of neuraxis metastases in children with diffuse pontine glioma.

PURPOSE: We performed a retrospective study of patients with diffuse pontine glioma (DPG) who suffered neuraxis metastasis (NM) and characterized the incidence, clinical features, radiologic findings, and patterns of disease dissemination. METHODS: Magnetic resonance imaging (MRI) of brain and spine was used to assess NM. Some patients also underwent magnetic resonance spectroscopy (MRS) (6 patients) and fluorodeoxyglucose positron emission tomography (FDG-PET) scans (13 patients) to further evaluate areas of metastatic disease. Three patients had histologic confirmation of disease at the site of NM. RESULTS: Between 1986 and 2003, 18 of 96 patients (17.3%) with DPG developed NM. The median age at diagnosis was 8 years (range, 4-17). All patients had adjuvant chemotherapy and/or focal radiotherapy at diagnosis. The NM occurred at a median of 15 months from diagnosis of DPG (range, 3-96). Three patterns of NM were seen on MRI of brain and spine in these patients; 8 (39%) had parenchymal (PM), 4 (22%) leptomeningeal (PM), 2 (11%) subependymal, and in 5 a combination of two or more patterns. The MRS and FDG-PET scan of suspected areas of metastatic disease was consistent with tumor in 6 of 6 and 12 of 13 patients who underwent these procedures respectively. Three patients also had histologic confirmation of malignant glioma at the site of NM. Despite salvage therapy, all 18 patients have died of disease at a median of 5 months (range, 0.5-20) from diagnosis of neuraxis spread. CONCLUSION: Our study emphasizes the need for screening patients with DPG for NM at the time of recurrence.
