Children with non-central nervous system tumors treated with platinum-based chemotherapy are at risk for hearing loss and cognitive impairments.

Background: Childhood cancer survivors (CCS) with chemotherapy induced sensorineural hearing loss (SNHL) are at risk for neurocognitive impairments. The purpose of this study was to determine the relationship between SNHL and cognitive function among CCS. Procedure: Inclusion: non-CNS solid tumor diagnosis; history of platinum chemotherapy (cisplatin and/or carboplatin); 8-17 years of age; off anti-cancer treatment for ≥6 months; and English speaking. Exclusion: history of intrathecal chemotherapy, cranial radiation, or baseline neurocognitive disorder. Participants completed the NIH Toolbox Cognition Battery at enrollment. T-tests were used to compare participants with normal hearing to those with hearing loss and the total sample with established Toolbox normative data (mean: 50; SD: 10). Results: Fifty-seven individuals enrolled; 52 completed full cognitive testing. Participants were on average 12.2 years of age and 7.0 years since treatment completion. Twenty-one participants (40%) received cisplatin, 27 (52%) carboplatin, and 4 (8%) received both. Fifteen participants (29%) demonstrated SNHL based on the better ear. CCS, regardless of the presence or absence of SNHL, demonstrated significantly lower mean cognitive skills compared to the normative sample in attention, executive function, language- vocabulary and oral reading, processing speed, and fluid, crystallized and total composite scores (all p < 0.01). Participants with SNHL had significantly lower crystallized composite (vocabulary, oral reading) than those with normal hearing (41.9 vs. 47.2, p < 0.05, Cohen's d = 0.62). Conclusions: CCS at risk for platinum induced hearing loss but without cranial radiation or intrathecal chemotherapy exposure demonstrate impaired cognitive skills and those with SNHL demonstrate lower crystallized composite scores.

Assessing quality of life in childhood cancer survivors at risk for hearing loss: a comparison of HEAR-QL and PROMIS measures.

Background: Childhood cancer survivors (CCS) exposed to platinum chemotherapy are at an increased risk of developing hearing loss and reporting decreased quality of life (QOL). This study compared two QOL measures; one developed for children with hearing loss, The Hearing Environments and Refection on Quality of Life (HEAR-QL), and one validated in CCS, the Patient-Reported Outcomes Measurement Information System (PROMIS), to assess their ability to evaluate QOL deficits in this population. Methods: Subject eligibility were restricted to CCS exposed to platinum-based chemotherapy but who were free of known risk factors for cognitive impairment, (non-central nervous system tumor, no cranial radiation, or intrathecal chemotherapy). Participants had to be between 8-17 years, have completed anti-cancer therapy for at least 6 months, and have an audiogram within 1 year, Participants completed the HEAR-QL-26 (7-12 years) or the HEAR-QL-28 (13-18 years) and the PROMIS. Independent samples and/or one sample T-tests were utilized to compare participants with normal hearing and hearing loss, and to compare outcome measures to normative HEAR-QL and PROMIS data. Non-parametric correlations were utilized to evaluate the relationship between QOL and demographic and medical variables, and QOL and severity of hearing loss. Results: Fifty-four CCS were evaluable. The mean age was 12.0 years. Twenty-eight participants (51.9%) received cisplatin, 30 (55.6%) carboplatin, and 4 (7.4%) received both. Twenty participants (37%) demonstrated hearing loss. Participants with hearing loss scored significantly lower on the HEAR-QL than those with normal hearing (mean: 70.3, SD: 21.7, vs mean: 88.0, SD: 9.3, p =.004 for the HEAR-QL-26; mean: 84.7, SD: 10.2 vs mean: 94.8, SD: 3.4, p =.040 for the HEAR-QL-28). Participants with normal hearing scored significantly lower on the HEAR-QL-26 than the normative mean (mean: 88, SD: 9.3, normative mean: 98, SD: 5, p =.000). The PROMIS failed to identify any differences in QOL between participants based on hearing status, or when compared to the normative mean. Conclusion: The HEAR-QL was more sensitive than the PROMIS in identifying QOL deficits in CCS at risk for hearing loss. The HEAR-QL should be considered in studies seeking to improve the QOL of CCS with hearing loss.

Prevalence of hearing screening failures in low-risk childhood cancer survivors.

BACKGROUND: We sought to estimate the frequency of hearing screening failures in pediatric cancer survivors at low risk for hearing loss and evaluate the feasibility of administering screenings in this population. PROCEDURE: Survivors in the St. Louis Children's Hospital Late Effects Clinic were recruited. Eligibility included (a) diagnosis of a pediatric cancer treated without platinum chemotherapy or cranial radiation, (b) at least 6 months from completion of therapy, (c) between the ages of 7 and 18 years, (d) cognitively/behaviorally able to participate, and (e) English speaking. Behavioral hearing screenings from 1000 to 8000 Hz were performed by trained personnel using a calibrated audiometer. A failed screen was defined by a participant not responding to two or more of the three screening attempts for at least one frequency in at least one ear. RESULTS: One hundred nine patients met eligibility criteria with 78 enrolled (71.5%). Diagnoses included leukemia (57.7%), sarcoma (11.5%), Wilms tumor (14.1%), lymphoma (12.8%), and other solid tumors (3.9%). The median age was 13.2 years (Q1-Q3: 9.6-15.4) and the median time from treatment completion was 3.7 years (Q1-Q3: 2.3-7.4). Eighteen patients (23%) failed the hearing screen (95% CI: 14%-34%). No demographic or treatment-related variables were significantly correlated to screening failure. Six screen failures (33%) underwent formal audiology assessments, with three demonstrating unilateral hearing loss: two conductive and one sensorineural. CONCLUSIONS: A significant fraction of pediatric cancer survivors at low risk for hearing loss failed hearing screening. Broader use of hearing screening should be considered.

Cisplatin Ototoxicity: Examination of the Impact of Dosing, Infusion Times, and Schedules In Pediatric Cancer Patients.

BACKGROUND: Sensorineural hearing loss is a well-known side effect of cisplatin (CDDP). There is limited research on the effect of dosing, infusion times, and schedules of cisplatin administration and their impact on hearing loss. METHODS: A retrospective review of 993 pediatric patients' medical and audiological charts from August 1990 to March 2015 was conducted using stringent inclusion criteria to characterize patients with hearing loss. 248 of these patients received CDDP. Of these, 216 patients had sufficient CDDP infusion data to assess for sensorineural hearing loss attributable to CDDP and its associated risk factors. Chart reviews were performed to extract clinical data including CDDP dosing information. Demographic and clinical characteristics were summarized by descriptive statistics, and univariate and multivariate logistic regressions were performed to examine the relationship between hearing loss and specific parameters of cisplatin administration (amount infused per dose, prescribed infusion time, total number of doses, number of doses per cycle, number of cycles, cumulative cisplatin exposure). Stepwise variable selection procedure was performed in the multivariate model building to extract the best subset of risk factors for the prediction of hearing loss and worsening ototoxicity grade using an established ototoxicity grading scale from the International Society of Pediatric Oncology (SIOP). RESULTS: A total of 153 patients with complete medical and audiologic data were evaluable for analysis. Hearing loss was identified in 72.6% of the patients. Multivariate analysis revealed that age [OR=0.90 (0.84-0.97), p-value=0.0086], radiation to any part of the body, [OR=3.20 (1.29-7.93), p-value=0.012], amount infused per dose (mg/m2) [OR=1.018 (1.002-1.033), p-value=0.029], and cumulative cisplatin exposure (mg/m 2) [OR=1.004 (1-1.008), p-value=0.027] were associated with hearing loss. Similar associations were also found between these risk factors and worsening SIOP grade. CONCLUSION: In one of the largest studies examining the influence of CDDP dosing and schedules on hearing loss, we found the amount of CDDP infused per dose is a significant risk factor. Considerations in designing regimens that reduce the amount of CDDP infused per dose may reduce the risk of hearing loss. Randomized prospective trials are needed.

Patient and Parent Decision-Making in the Setting of Chemotherapy-Induced Sensorineural Hearing Loss.

OBJECTIVES: Children with malignancies may be exposed to ototoxic therapies resulting in sensorineural hearing loss (SNHL). There is no consensus as to when intervention with amplification is necessary due to a variety of factors such as disease status, speech and language development, perceived difficulty with communication, and limitations of technology to fit these challenging losses. The decision to proceed with amplification after cancer can be difficult for patients and families. The purpose of this study is (1) to understand the decision-making (DM) process of childhood cancer survivors (CCSs) with SNHL and their parents and (2) to identify their decisional needs. DESIGN: Semi-structured interviews guided by the Ottawa's decision support framework were recorded and transcribed verbatim. Inclusion criteria were CCSs ages 8 to 30 years old with a Chang grade >1b SNHL and off-therapy; parents of this group were also eligible. Patients with active disease were excluded. Prompts inquired of sources of decisional conflict, role in DM, and DM behaviors. Inductive content analysis of the narrative qualitative data was used. RESULTS: Seven parents of CCSs and 6 CCSs participated. Themes in the CCS group included: (1) making sense of ototoxic SNHL; (2) desiring personalized education and treatment of SNHL; (3) playing an active role in the joint DM process; and (4) accepting hearing aids requires time and effort. The parent group shared the first and last theme with the CCS group and had two unique themes: (1) needing experts to respect the individual's journey to SNHL acceptance and (2) moving past the cancer experience to acceptance. Parents more often framed their DM within the context of already experiencing the trauma of cancer, whereas CCSs did not. One parent said, "You see all the rubble and you've lived through the devastation of the storm, but now you got to figure out what's broken." CCSs expressed bodily concerns regarding amplification, such as discomfort to the ear and difficulty in adjusting to the volume. The following needs were identified: early, re-enforced education regarding late effects risks; open communication among providers, CCSs, and parents; and audiogram result interpretations in patient- and parent-friendly language. CONCLUSIONS: Understanding the DM process from the CCS and parent's perspectives should be considered when providing counseling for hearing amplification in the setting of cancer-related SNHL. Earlier and consistent delivery of late effects education, open communication regarding risk for SNHL, and improved delivery of audiogram results should be targets for meeting unmet needs. These findings should inform the development of decision aids to reduce decisional conflict in this population.

Physician Support for Non-Physician Advanced Practice Providers for Persons With Cardiopulmonary Disease.

BACKGROUND: The use of non-physician advanced practice providers (NPAPP) has increased in the United States to offset shortages in the physician workforce. Yet there are still gaps in some locations where there is little to no access to quality health care. This study sought to identify whether physicians perceived a workforce gap and their level of interest in hiring an NPAPP with cardiopulmonary expertise to fill the perceived gap. METHODS: An American Association for Respiratory Care (AARC)-led workgroup surveyed 1,401 physicians in 6 different specialties. The survey instrument contained 32 closed-ended questions and 4 open-ended questions. RESULTS: 74% of the 1,401 physician respondents agreed or strongly agreed that there will be a future need for an NPAPP with cardiopulmonary expertise. Respondents from sleep, pediatrics, pulmonary, and critical care were most likely to indicate that there is a current need for an NPAPP. A majority of respondents perceived that the specialized NPAPP would improve efficiency and productivity (74%), patient experience (73%), and patient outcomes (72%). Interest in adding this NPAPP did not increase when participants were told to presume authority for hiring, budget, and reimbursement. CONCLUSIONS: These results indicate that there is both a need for and an interest in hiring an NPAPP with cardiopulmonary expertise. Having an NPAPP would boost physician efficiency and productivity, improve the patient care experience, and provide benefits that other clinicians are not trained to provide to persons with cardiopulmonary disease. Results suggest there should be continued efforts to develop the NPAPP role to add value for physicians and patients alike.

Prevalence of Ototoxicity Following Hematopoietic Stem Cell Transplantation in Pediatric Patients.

The use of hematopoietic stem cell transplantation (HSCT) is increasing for a variety of diseases. Ototoxicity from this procedure has not been extensively studied. A retrospective chart review examined 275 patients from this institution who underwent HSCT between January 1, 2007, and April 30, 2017. Data extracted included therapy before HSCT and the subsequent course of transplantation. Evaluable patients had complete medical records and interpretable audiograms available. Ototoxicity constituted significant threshold changes from baseline or changes in International Society of Pediatric Oncology/Boston Ototoxicity Grading Scale (SIOP) grade comparing audiogram results just before HSCT with those following the transplantation procedure. A total of 147 patients were evaluable. Ototoxicity was observed in 10.2% of the patients. Higher SIOP grade before HSCT was significantly associated with a higher risk of post-transplantation ototoxicity (P < .01). Previous cisplatin treatment (P < .0001), but not carboplatin or radiation treatment, was also associated with ototoxicity. Patients with a solid tumor or brain tumor (P < .0001) and those who received an autologous transplant (P = .0002) were also at increased risk. No post-transplantation event was significantly associated with ototoxicity. Ototoxicity affects a significant percentage of patients undergoing HSCT, and careful monitoring is needed to identify patients impacted by this procedure.

Prevalence and nature of hearing loss in a cohort of children with sickle cell disease.

BACKGROUND: Sickle cell disease (SCD) may cause injury to any organ, including the auditory system. Although the association of SCD and hearing loss has been described, the nature of this complication is unknown. We sought to establish the prevalence and nature of hearing loss in a referred cohort of children with SCD and to identify correlating disease- or treatment-associated factors. PROCEDURE: We conducted a retrospective review of patients with SCD < 22 years of age who had hearing evaluations between August 1990 and December 2014. Demographics, audiograms, and disease and treatment variables were analyzed. RESULTS: Two hundred and ten audiograms among 81 patients were reviewed, and 189 were evaluable. Seventy-two children constituted the referred cohort. Fourteen (19.4%) had hearing loss documented on at least one audiogram. Seven (9.7%) patients had only conductive hearing loss, and the loss persisted for up to 10.3 years. The median age of first identification was eight years. Six (8.3%) patients had hearing loss that was at least partially sensorineural. One patient's hearing loss was ambiguous. All sensorineural hearing losses were unilateral and 4/6 patients had prior documented normal hearing, indicating acquired loss. No correlations were identified. CONCLUSIONS: Both conductive and sensorineural hearing losses are more prevalent in our study population than those observed in the general pediatric population. In children with SCD, sensorineural hearing loss appears to be acquired and unilateral. Conductive hearing loss was identified in older children and can persist. Serial screening is needed for early detection and more prompt intervention in this population.

Asymmetric sensorineural hearing loss is a risk factor for late-onset hearing loss in pediatric cancer survivors following cisplatin treatment.

BACKGROUND: Ototoxicity is a significant complication of cisplatin treatment. Hearing loss can be symmetric or asymmetric, and may decline after therapy. This study examined the risks of asymmetric and late-onset hearing loss (LOHL) in cisplatin-treated pediatric patients with cancer. METHODS: A retrospective review of 993 patients' medical and audiological charts from August 1990 to March 2015 was conducted using stringent criteria to characterize patients with asymmetric hearing loss (AHL) or LOHL. Audiologic data were reviewed for 248 patients that received cisplatin to assess cisplatin-induced sensorineural hearing loss and its associated risk factors. RESULTS: Of the patients evaluable for AHL, 26% exhibited this finding. Of those evaluable for LOHL, 42% of the patients' hearing worsened more than 6 months after therapy completion. Radiation and type of cancer diagnosis were major risk factors for both AHL and LOHL. Furthermore, LOHL was linked to age of diagnosis, noncranial radiation, and longer audiologic follow-up. AHL was strongly associated with LOHL-60% of patients with AHL also had LOHL. Logistic regression analysis revealed that patients with AHL (OR 6.3, 95% CI: 2.2-17.8, P = 0.0005) or those receiving radiation (OR 3.2, 95% CI: 1.2-8.6, P = 0.02) were at greatest risk for LOHL. CONCLUSION: Children receiving cisplatin therapy are at risk for developing AHL and LOHL. Those that have received radiation and/or with AHL are at increased risk for further hearing decline. Long-term monitoring of these patients is important for early intervention as hearing diminishes.

Determining the prevalence of vestibular screening failures in pediatric cancer patients whose therapies include radiation to the head/neck and platin-based therapies: A pilot study.

BACKGROUND: Sensorineural hearing loss due to ototoxic cancer therapy is well established; effects on the vestibular system are unknown. We examined the feasibility of implementing vestibular screens for pediatric cancer survivors exposed to ototoxic agents. The prevalence of screening failures is reported. METHODS: Cancer survivors who were 6-17 years, at least 1-month posttreatment, and received ototoxic therapy (radiation to the head/neck, cisplatin, carboplatin) were eligible. Screening measures included (1) Pediatric Vestibular Symptom Questionnaire, (2) Modified Clinical Test of Sensory Interaction on Balance, and (3) Dynamic Visual Acuity. RESULTS: Vestibular screening failures were observed in 30 participants (60%). Patients with a brain tumor diagnosis were at increased risk for failures compared to nonbrain tumor patients (74.2% vs. 36.8%, P = 0.009). Patients who underwent brain surgery were at increased risk for failures compared to patients without brain surgery (71% vs. 42%, P = 0.043). Patients with a longer duration between end of treatment and vestibular screening had a reduced risk of failures, with an almost 20% decrease for each year between the time points (odds ratio = 0.812; 95% confidence interval: 0.683-0.964, P = 0.018). Receiving carboplatin correlated with a decreased risk of failure (P = 0.016), due to a negative correlation with other clinical risk factors (diagnosis of a brain tumor, major brain surgery) that are associated with vestibular screening failure. CONCLUSION: Vestibular screening failures are highly prevalent in childhood cancer survivors who received ototoxic therapy. Broad screening of this population and further characterization of these patients are warranted.

Treating Women Who Are Pregnant and Parenting for Opioid Use Disorder and the Concurrent Care of Their Infants and Children: Literature Review to Support National Guidance.

OBJECTIVES: The prevalence of opioid use disorder (OUD) during pregnancy is increasing. Practical recommendations will help providers treat pregnant women with OUD and reduce potentially negative health consequences for mother, fetus, and child. This article summarizes the literature review conducted using the RAND/University of California, Los Angeles Appropriateness Method project completed by the US Department of Health and Human Services Substance Abuse and Mental Health Services Administration to obtain current evidence on treatment approaches for pregnant and parenting women with OUD and their infants and children. METHODS: Three separate search methods were employed to identify peer-reviewed journal articles providing evidence on treatment methods for women with OUD who are pregnant or parenting, and for their children. Identified articles were reviewed for inclusion per study guidelines and relevant information was abstracted and summarized. RESULTS: Of the 1697 articles identified, 75 were included in the literature review. The perinatal use of medication for addiction treatment (MAT, also known as medication-assisted treatment), either methadone or buprenorphine, within comprehensive treatment is the most accepted clinical practice, as withdrawal or detoxification risks relapse and treatment dropout. Medication increases may be needed with advancing pregnancy, and are not associated with more severe neonatal abstinence syndrome (NAS). Switching medication prenatally is usually not recommended as it can destabilize opioid abstinence. Postnatally, breastfeeding is seen as beneficial for the infant for women who are maintained on a stable dose of opioid agonist medication. Less is known about ideal pain management and postpartum dosing regimens. NAS appears generally less severe following prenatal exposure to buprenorphine versus methadone. Frontline NAS medication treatments include protocol-driven methadone and morphine dosing in the context of nonpharmacological supports. CONCLUSIONS: Women with OUD can be treated with methadone or buprenorphine during pregnancy. NAS is an expected and manageable condition. Although research has substantially advanced, opportunities to guide future research to improve maternal and infant outcomes are provided.

Screening, Brief Intervention and Referral to Treatment (SBIRT): rationale, program overview and cross-site evaluation.

AIMS: Since 2003, the US Substance Abuse and Mental Health Services Administration, Center for Substance Abuse Treatment (SAMHSA, CSAT) has awarded 32 Screening, Brief Intervention and Referral to Treatment (SBIRT) grants to states, territories and tribal organizations to enhance services for persons with, or at risk for, substance use disorders. The grants supported an expansion of the continuum of care to include screening, brief intervention, brief treatment and referral to treatment in general medical and community settings. This paper describes the SAMHSA SBIRT program in the context of the scientific research that motivated its development, as well as the two cross-site evaluations that are the subject of subsequent papers in this Supplement. METHODS: A narrative review of research evidence pertaining to SBIRT and of the cross-site evaluation design that made it possible to determine whether the SAMHSA SBIRT grant program achieved its intended aims. The 11 programs within the two cohorts of grant recipients that were the subject of the cross-site evaluations are described in terms of SBIRT service components, performance sites, providers, management structure/activities and patient/client characteristics. CONCLUSION: The US SAMHSA SBIRT program is an effective way to introduce a variety of new services that extend the continuum of care for substance-involved individuals, ranging from early intervention with non-dependent substance users to referral of more serious cases to specialized substance abuse treatment.

Sustaining Screening, Brief Intervention and Referral to Treatment (SBIRT) services in health-care settings.

AIMS: To assess the sustainability of Screening, Brief Intervention and Referral to Treatment (SBIRT) services after cessation of initial start-up funding. DESIGN: Descriptive study with quantitative and qualitative data collected from 34 staff participants from six grantees (comprising 103 sites) funded previously through a large, federally supported SBIRT program. SETTING: Primary care out-patient clinics and hospitals in the United States. PARTICIPANTS: Thirty-four grantee-related staff members, including administrators, evaluators, key stakeholders and SBIRT service providers from six grantees. MEASUREMENTS: Changes to levels and types of service delivery activities after federal funding stopped, alternative sources of funding and obstacles to delivery of services. FINDINGS: Of the 103 original sites in the six SBIRT grantee programs, 69 sites continued providing services in some capacity (same as before, reduced, modified or expanded). Most of the 69 sites (67%) adapted and redesigned the delivery of SBIRT services post-initial grant funding. In addition, new sites were added after grant funding ended, bringing the total number of sites to 88. Analysis of participant responses identified four primary factors that influenced SBIRT sustainability: presence of champions, funding availability, systemic change and SBIRT practitioner characteristics. CONCLUSIONS: Almost 70% of the Screening, Brief Intervention and Referral to Treatment (SBIRT) services in the United States funded initially through a federal program were able to sustain operations after federal funding ceased and some expanded SBIRT services beyond the original sites. The key factors related to sustainability were securing new funding, having champions, adapting and making system changes and managing program staffing challenges.

Auditory complications in childhood cancer survivors: a report from the childhood cancer survivor study.

BACKGROUND: Studies have found associations between cancer therapies and auditory complications, but data are limited on long-term outcomes and risks associated with multiple exposures. PROCEDURE: The Childhood Cancer Survivor Study is a retrospective cohort investigating health outcomes of long-term survivors (5+ years) diagnosed and treated between 1970 and 1986 compared to a randomly selected sibling cohort. Questionnaires were completed by 14,358 survivors of childhood cancer and 4,023 sibling controls. Analysis determined the first occurrence of four auditory conditions in two time periods: diagnosis to 5 years post-diagnosis, and ≥ 5 years post-diagnosis. Multivariable analyses determined the relative risks (RR) and 95% confidence interval (CI) of auditory conditions by treatment exposure. RESULTS: Five or more years from cancer diagnosis, survivors were at increased risk of problems hearing sounds (RR = 2.3; 95% CI: 1.8-2.8), tinnitus (RR = 1.7; 95% CI: 1.4-2.1), hearing loss requiring an aid (RR = 4.4; 95% CI: 2.8-6.9), and hearing loss in 1 or both ears not corrected by a hearing aid (RR = 5.2; 95% CI: 2.8-9.5), when compared to siblings. Temporal lobe and posterior fossa radiation was associated with these outcomes in a dose-dependent fashion. Exposure to platinum compounds was associated with an increased risk of problems hearing sounds (RR = 2.1; 95% CI: 1.3-3.2), tinnitus (RR = 2.8; 95% CI: 1.9-4.2), and hearing loss requiring an aid (RR = 4.1; 95% CI: 2.5-6.7). CONCLUSIONS: Childhood cancer survivors are at risk of developing auditory complications. Radiation and platinum compounds are determinants of this risk. Follow-up is needed to evaluate the impact of auditory conditions on quality of life.

Late onset hearing loss: a significant complication of cancer survivors treated with Cisplatin containing chemotherapy regimens.

Cisplatin is a known ototoxic agent and has been associated with late onset hearing loss (LOHL) in children beyond completion of treatment. We completed a retrospective review of 160 patients yielding 59 who received cisplatin and had sufficient data to determine the presence of LOHL. LOHL was defined as a significant change in hearing thresholds 6 months past the last cisplatin therapy. A significant change was defined as a decrease of >15 dB in a frequency from 1 to 8 kHz in either ear, or a decrease of 10 dB at 2 or more frequencies in the same ear, compared with the previously entered audiogram. Hearing loss was classified using the Brock grading system for each ear. Of the 59 patients evaluated, 51% exhibited LOHL. Univariate analysis indicated LOHL was significantly associated with age of diagnosis (P=0.031), diagnosis of medulloblastoma (P=0.035), hearing aids (P=0.010), and cranial radiation (P=0.044), particularly to the posterior fossa (P=0.023). Multivariate analysis revealed only radiation to the posterior fossa (P=0.02) and the use of hearing aids (P=0.01) were significantly associated with LOHL. LOHL is a significant complication in childhood cancer survivors who receive cisplatin. Long-term audiologic monitoring after therapy is needed to identify the affected patients.

Encouraging physicians to screen for and intervene in substance use disorders: obstacles and strategies for change.

The scientific literature was reviewed to identify obstacles and effective ways to improve primary care physician screening, interventions, and management of patient substance use disorders (SUDs). Major obstacles identified are physician lack of skills and self-efficacy in patient counseling, inadequate training at all levels of medical education, and lack of reimbursement and other health care systems support for services to patients. Physician abuse of drugs does not appear to be a major obstacle. Physician attitudes about patients with SUDS and the effectiveness of treatment services need to be addressed. Research points to the use of a multifaceted change strategy. Key components include practice-based training emphasizing screening and counseling skills throughout medical education, clinical systems to ensure regular SUD services (screening, intervention, and referral) to patients, and reimbursement and coverage systems to support physician interventions and patient services.

Hearing loss in pediatric oncology patients receiving carboplatin-containing regimens.

Carboplatin is a well-established chemotherapeutic agent used to treat a variety of pediatric malignancies. Platinum analogues such as cisplatin are known to be ototoxic, but little is known regarding the ototoxicity of carboplatin. We performed a single institution retrospective chart review of pediatric oncology patients who received platinum-containing regimens from 1993 to 2002. Ninety-nine patients with sufficient medical and audiologic data were identified. Significant hearing loss was defined as a Brock grade 1 or higher. The incidence was compared among 3 treatment groups (carboplatin only, carboplatin and cisplatin, and cisplatin only). Significant hearing loss in patients receiving carboplatin only was rare, observed in only 1/25 (4%) of patients. In contrast, 19/27 (70%) of patients receiving carboplatin and cisplatin possessed significant hearing loss, as did 27/47 (57%) of those patients receiving cisplatin only P<0.001. The difference in hearing loss could not be explained by different cumulative exposures of the platinum agents. Carboplatin, when used without cisplatin, is rarely associated with severe hearing loss, even at high cumulative doses.

A national study of the substance abuse treatment workforce.

This study's purpose is to gain a current perspective on the substance abuse treatment field's workforce. The data are from the Retrospective Study of treatment professionals designed to document how the Treatment Improvement Protocols published by the Center for Substance Abuse Treatment have influenced the implementation of best practices. The Retrospective Study consisted of a two-wave cross-sectional survey with telephone follow-up. Data for this study were from demographic information on Wave 1 study participants, which had a response rate of 80.1% (N = 3,267). The results of the study showed that most treatment professionals are White (84.5%) and middle-aged (i.e., between 40 and 55 years old) and slightly more are female (50.5.0%) than male (49.5%). Treatment professionals tend to enter the field and stay in it, and almost 80.0% of respondents possess a bachelor's degree or higher. In addition, most treatment professionals are licensed or certified and treat clients from different racial and ethnic backgrounds than themselves. Implications for the provision of treatment services are discussed.
