BackgroundSustainability, or continued use of evidence-based interventions for long-term patient benefit, is the least studied aspect of implementation science. In this study, we evaluate sustainability of a Pediatric Early Warning System (PEWS), an evidence-based intervention to improve early identification of clinical deterioration in hospitalized children, in low-resource settings using the Clinical Capacity for Sustainability Framework (CCS).MethodsWe conducted a secondary analysis of a qualitative study to identify barriers and enablers to PEWS implementation. Semi-structured interviews with PEWS implementation leaders and hospital directors at 5 Latin American pediatric oncology centers sustaining PEWS were conducted virtually in Spanish from June to August 2020. Interviews were recorded, professionally transcribed, and translated into English. Exploratory thematic content analysis yielded staff perceptions on PEWS sustainability. Coded segments were analyzed to identify participant perception about the current state and importance of sustaining PEWS, as well as sustainability successes and challenges. Identified sustainability determinants were mapped to the CCS to evaluate its applicability.ResultsWe interviewed 71 staff including physicians (45%), nurses (45%), and administrators (10%). Participants emphasized the importance of sustaining PEWS for continued patient benefits. Identified sustainability determinants included supportive leadership encouraging ongoing interest in PEWS, beneficial patient outcomes enhancing perceived value of PEWS, integrating PEWS into the routine of patient care, ongoing staff turnover creating training challenges, adequate material resources to promote PEWS use, and the COVID-19 pandemic. While most identified factors mapped to the CCS, COVID-19 emerged as an additional external sustainability challenge. Together, these challenges resulted in multiple impacts on PEWS sustainment, ranging from a small reduction in PEWS quality to complete disruption of PEWS use and subsequent loss of benefits to patients. Participants described several innovative strategies to address identified challenges and promote PEWS sustainability.ConclusionThis study describes clinician perspectives on sustainable implementation of evidence-based interventions in low-resource settings, including sustainability determinants and potential sustainability strategies. Identified factors mapped well to the CCS, however, external factors, such as the COVID pandemic, may additionally impact sustainability. This work highlights an urgent need for theoretically-driven, empirically-informed strategies to support sustainable implementation of evidence-based interventions in settings of all resource-levels.

BackgroundPediatric Early Warning Systems (PEWS) reduce clinical deterioration, improve interdisciplinary communication, and provide cost savings; however, little is known about how these impacts are achieved or related. This study evaluates the multi-level impacts of PEWS in resource-limited pediatric oncology centers.MethodsWe conducted 71 semi-structured interviews including physicians (45%), nurses (45%), and administrators (10%) from 5 resource-limited pediatric oncology centers in 4 Latin American countries. Interviews were conducted in Spanish, transcribed, and translated into English. A code book was developed using a priori and inductively derived codes. Transcripts were independently coded by 2 coders, achieving a kappa of 0.8-0.9. Thematic content analysis explored perceived impacts of PEWS at the level of the patient, clinician, healthcare team, and institution.ResultsPEWS improved the quality of attention for patients, reducing morbidity and mortality. Clinicians felt more knowledgeable, confident, and empowered providing patient care, resulting in greater job satisfaction. PEWS affected team dynamics by improving interdisciplinary (ward and intensive care unit) and interprofessional (physicians and nurses) relationships and communication. This ultimately led to institutional culture change with emphasis on patient safety, collaboration with other centers, and receipt of institutional awards. Together, these impacts led to hospital-wide support of ongoing PEWS use.ConclusionsIn resource-limited hospitals, PEWS use results in multi-level positive impacts on patients, clinicians, teams, and institutions, creating a feedback loop that further supports ongoing PEWS use. These findings can guide advocacy for PEWS to various stakeholders, improve PEWS effectiveness, and inform assessment of other interventions to improve childhood cancer outcomes.

OBJECTIVE The objectives of this study were to determine the overall survival (OS) and event-free survival (EFS) rates of patients with medulloblastoma treated in a national pediatric hospital in Peru, as well as to identify demographic, clinical, imaging, postoperative, and histopathological characteristics and prognostic factors associated with OS and EFS. METHODS The authors conducted a retrospective study analyzing information from the medical records of children with a diagnosis of medulloblastoma who underwent surgical treatment at the Instituto Nacional de Salud del Niño—San Borja, a public hospital in Lima, Peru, from 2015 to 2020. Clinical-epidemiological variables, degree of disease extension, risk stratification, extent of resection, postoperative complications, status of oncological treatment received, histological subtype, and neurological sequelae were taken into account. The Kaplan-Meier method and Cox regression analysis were used to estimate OS, EFS, and prognostic factors. RESULTS Of the 57 children evaluated with complete medical records, only 22 children (38.6%) underwent complete oncological treatment. OS was 37% (95% CI 0.25–0.55) at 48 months. EFS was 44% (95% CI 0.31–0.61) at 23 months. High-risk stratification—meaning patients with ≥ 1.5 cm2 of residual postoperative tumor, those younger than 3 years, those with disseminated disease (HR 9.69, 95% CI 1.40–67.0, p = 0.02), and those who underwent subtotal resection (HR 3.78, 95% CI 1.09–13.2, p = 0.04)—was negatively associated with OS. Failure to receive complete oncological treatment was negatively associated with OS (HR 20.0, 95% CI 4.84–82.6, p < 0.001) and EFS (HR 7.82, 95% CI 2.47–24.7, p < 0.001). CONCLUSIONS OS and EFS of patients with medulloblastoma in the author’s milieu are below those reported in developed countries. Incomplete treatment and treatment abandonment in the authors’ cohort were also high compared with high-income country statistics. Failure to complete oncological treatment was the most important factor associated with poor prognosis, both in terms of OS and EFS. High-risk patients and subtotal resection were negatively associated with OS. Interventions are needed to promote the completion of adjuvant oncological therapy for medulloblastoma in the disadvantaged Peruvian population.

BACKGROUND: Low-grade gliomas (LGG) are the most common central nervous system (CNS) tumors in children. Peru is an index country for the Global Initiative for Childhood Cancer (GICC). As part of the Initiative, a multidisciplinary brain tumor team was formed in 2020 that includes five national reference centers: National Institute of Neoplastic Diseases, National Children’s Health Institute-San Borja, National Children’s Health Institute-Breña, Edgardo Rebagliati Martins National Hospital and Guillermo Almenara Irigoyen National Hospital. This multicenter study sought to evaluate the survival and prognostic factors of patients younger than 18 years diagnosed with LGG, an index cancer for the GICC. METHODS: A retrospective study included all patients diagnosed with LGG in the five centers between 2014 and 2018. We analyzed clinical characteristics, histology, and treatment modalities. We used the Kaplan-Meier method for survival. RESULTS: 194 patients were registered; 136 patients were included. M/F ratio was 1.2, mean age 7 years old. The most frequent location was infratentorial (42.2%), supratentorial (34.9%), optic/chiasm/sellar (11%) and brainstem (11.9%). The most frequent histological types were pilocytic astrocytoma (61%), diffuse astrocytoma (10.3%), oligodendroglioma (5.2%), and other low-grade neoplasms (23.5%). Surgery was performed in 109 patients (83.2%). Chemotherapy alone was used in 17 (12.5%), while radiotherapy in 20 (14.7%). Overall survival at 5 years was 82.9% (95% CI 73.3 - 89.4). Age younger than 3 years (p=0.002), diffuse histological type (p=0.04), and location in the brainstem (p=0.001) were factors associated with a worse prognosis. CONCLUSIONS: Within the framework of the GICC, this work is one of the first steps to understand the current context of pediatric CNS tumor care in Peru. Although the reported survival rate is about the GICC goal of 60%, further improvements in care are needed to increase survival to level closer to high-resource setting and decrease long term morbidity.
