Strategies to improve outcomes of children with cancer in low-income countries

Sustainable care for children with cancer: a Lancet Oncology Commission

We estimate that there will be 13·7 million new cases of childhood cancer globally between 2020 and 2050. At current levels of health system performance (including access and referral), 6·1 million (44·9%) of these children will be undiagnosed. Between 2020 and 2050, 11·1 million children will die from cancer if no additional investments are made to improve access to health-care services or childhood cancer treatment. Of this total, 9·3 million children (84·1%) will be in low-income and lower-middle-income countries. This burden could be vastly reduced with new funding to scale up cost-effective interventions. Simultaneous comprehensive scale-up of interventions could avert 6·2 million deaths in children with cancer in this period, more than half (56·1%) of the total number of deaths otherwise projected. Taking excess mortality risk into consideration, this reduction in the number of deaths is projected to produce a gain of 318 million life-years. In addition, the global lifetime productivity gains of US$2580 billion in 2020-50 would be four times greater than the cumulative treatment costs of $594 billion, producing a net benefit of $1986 billion on the global investment: a net return of $3 for every $1 invested. In sum, the burden of childhood cancer, which has been grossly underestimated in the past, can be effectively diminished to realise massive health and economic benefits and to avert millions of needless deaths.

Science and health for all children with cancer

Each year ~429,000 children and adolescents aged 0 to 19 years are expected to develop cancer. Five-year survival rates exceed 80% for the 45,000 children with cancer in high-income countries (HICs) but are less than 30% for the 384,000 children in lower-middle-income countries (LMICs). Improved survival rates in HICs have been achieved through multidisciplinary care and research, with treatment regimens using mostly generic medicines and optimized risk stratification. Children’s outcomes in LMICs can be improved through global collaborative partnerships that help local leaders adapt effective treatments to local resources and clinical needs, as well as address common problems such as delayed diagnosis and treatment abandonment. Together, these approaches may bring within reach the global survival target recently set by the World Health Organization: 60% survival for all children with cancer by 2030.

CYP3A5 genotype and its impact on vincristine pharmacokinetics and development of neuropathy in Kenyan children with cancer

BACKGROUND

Vincristine (VCR) is a critical part of treatment in pediatric malignancies and is associated with dose-dependent peripheral neuropathy (vincristine-induced peripheral neuropathy [VIPN]). Our previous findings show VCR metabolism is regulated by the CYP3A5 gene. Individuals who are low CYP3A5 expressers metabolize VCR slower and experience more severe VIPN as compared to high expressers. Preliminary observations suggest that Caucasians experience more severe VIPN as compared to nonCaucasians.

PROCEDURE

Kenyan children with cancer who were undergoing treatment including VCR were recruited for a prospective cohort study. Patients received IV VCR 2 mg/m² /dose with a maximum dose of 2.5 mg as part of standard treatment protocols. VCR pharmacokinetics (PK) sampling was collected via dried blood spot cards and genotyping was conducted for common functional variants in CYP3A5, multi-drug resistance 1 (MDR1), and microtubule-associated protein tau (MAPT). VIPN was assessed using five neuropathy tools.

RESULTS

The majority of subjects (91%) were CYP3A5 high-expresser genotype. CYP3A5 low-expresser genotype subjects had a significantly higher dose and body surface area normalized area under the curve than CYP3A5 high-expresser genotype subjects (0.28 ± 0.15 hr·m² /l vs. 0.15 ± 0.011 hr·m² /l, P = 0.027). Regardless of which assessment tool was utilized, minimal neuropathy was detected in this cohort. There was no difference in the presence or severity of neuropathy assessed between CYP3A5 high- and low-expresser genotype groups.

CONCLUSION

Genetic factors are associated with VCR PK. Due to the minimal neuropathy observed in this cohort, there was no demonstrable association between genetic factors or VCR PK with development of VIPN. Further studies are needed to determine the role of genetic factors in optimizing dosing of VCR for maximal benefit.

Community resources support adherence to treatment for childhood cancer in El Salvador

OBJECTIVE

In order to reduce nonadherence and treatment abandonment of children with cancer in El Salvador, institutions located nearby the patients' homes were involved to provide support. Methodological approach: Health clinics and municipality offices in the patients' communities were asked to assist families who were not promptly located after missing hospital appointments, or those whose financial limitations were likely to impede continuation of treatment. Data was collected about the number of contacted institutions, the nature of help provided, staff's time investments, and parents' perceptions about the intervention.

FINDINGS

Local institutions (133 from 206 contacts) conducted home visits (83), and/or provided parents with money (55) or transportation (60). Parents found this support essential for continuing the treatment but they also encountered challenges regarding local institutions' inconsistencies. Nonadherence and abandonment decreased.

IMPLICATIONS

Economic burden was reduced on both the families and the hospital. Involvement of external institutions might become regular practice to support families of children with cancer.

Addressing regional disparities in pediatric oncology: Results of a collaborative initiative across the Mexican-North American border

BACKGROUND

Cancer is emerging as a major cause of childhood mortality in low- and middle-income countries. In Mexico, cancer is the number one cause of death in children aged 5-14. Until recently, many children with cancer from Baja California, Mexico, went untreated. We reasoned that an initiative inspired by the St. Jude Children's Research Hospital (SJCRH) "twinning" model could successfully be applied to the San Diego-Tijuana border region. In 2008, a twinning project was initiated by Rady Children's Hospital, SJCRH, and the General Hospital Tijuana (GHT). Our aim was to establish a pediatric oncology unit in a culturally sensitive manner, adapted to the local healthcare system.

PROCEDURE

An initial assessment revealed that despite existence of basic hospital infrastructure at the GHT, the essential elements of a pediatric cancer unit were lacking, including dedicated space, trained staff, and uniform treatment. A 5-year action plan was designed to offer training, support the staff financially, and improve the infrastructure.

RESULTS

After 7 years, accomplishments include the opening of a new inpatient unit with updated technology, fully trained staff, and a dedicated, interdisciplinary team. Over 700 children have benefited from accurate diagnosis and treatment.

CONCLUSIONS

Initiatives that implement long-term partnerships between institutions along the Mexican-North American border can be highly effective in establishing successful pediatric cancer control programs. The geographic proximity facilitated accelerated training and close monitoring of project development. Similar initiatives across other disciplines may benefit additional patients and synergize with pediatric oncology programs to reduce health disparities in underserved areas.

Medulloblastoma With Extensive Nodularity: Tailored Therapy in a Low-resource Setting

Treatment for medulloblastoma carries significant risks, particularly in resource-constrained settings. We report a case of a Mexican infant with desmoplastic/nodular medulloblastoma. Given the nature of her tumor, we developed a tailored regimen following subtotal resection to avoid both radiation therapy and the high-dose cisplatin therapy offered at most centers in the United States. The patient is in remission 4 years after the initial diagnosis. This case suggests an alternative treatment plan for this particular tumor variant that accommodates the limited resources of many centers around the world and avoids the risks associated with radiation therapy at a young age.

Cancer registration for cancer control in Latin America: a status and progress report

Cancer incidence by type has been included as a core indicator in the World Health Organization (WHO) Global Monitoring Framework for the Prevention and Control of Noncommunicable Diseases. The Global Initiative for Cancer Registry Development (GICR), coordinated by the International Agency for Research on Cancer (IARC), supports low- and middle-income countries to reduce disparities in cancer information for cancer control by increasing the coverage and quality of cancer registration. A baseline assessment has been performed at the IARC Regional Hub for Latin America using secondary and public information sources. Countries have been categorized according to the following criteria for population-based cancer registries (PBCRs): 1) "has no established PBCR (but some registration activity)," 2) "has established PBCR(s) but none of high-quality," and 3) "has established, high-quality PBCR(s) (regional or national)." Currently, in LatinAmerica, most countries have cancer control plans in place; PBCRs cover approximately20% of the region's population, though only 7% are deemed as having high-quality information. No information is available on the extent of use of the information generated by PBCRs for cancer control purposes. Though there are important advances in cancer registration in the region, there is still much to be done. This report also outlines key elementsfor improving cancer surveillance in the region, including 1) involvement of local stakeholders and experts, 2) integration of cancer registries into existing surveillance systems(accounting for the complexities and particularities of cancer surveillance), 3) improvementin data availability and quality, 4) enhanced communication and dissemination, and 5) better linkages between cancer registries and cancer planning and cancer research.

Improving Pediatric Cancer Care Disparities Across the United States-Mexico Border: Lessons Learned from a Transcultural Partnership between San Diego and Tijuana

In 2007, the 5-year survival rate for children with acute leukemia in Baja California, Mexico was estimated at 10% (vs. 88% in the United States). In response, stakeholders at St. Jude Children’s Research Hospital, Rady Children’s Hospital San Diego, and the Hospital General de Tijuana (HGT) implemented a transcultural partnership to establish a pediatric oncology program. The aim was to improve clinical outcomes and overall survival for children in Baja California. An initial needs assessment evaluation was performed and a culturally sensitive, comprehensive, 5-year plan was designed and implemented. After six years, healthcare system accomplishments include the establishment of a fully functional pediatric oncology unit with 60 new healthcare providers (vs. five in 2007). Patient outcome improvements include a rise in 5-year survival for leukemia from 10 to 43%, a rise in new cases diagnosed per year from 21 to 70, a reduction in the treatment abandonment rate from 10% to 2%, and a 45% decrease in the infection rate. More than 600 patients have benefited from this program. Knowledge sharing has taken place between teams at the HGT and Rady Children’s Hospital San Diego. Further, one of the most significant outcomes is that the HGT has transitioned into a regional referral center and now mentors other hospitals in Mexico. Our results show that collaborative initiatives that implement long-term partnerships along the United States–Mexico border can effectively build local capacity and reduce the survival gap between children with cancer in the two nations. Long-term collaborative partnerships should be encouraged across other disciplines in medicine to further reduce health disparities across the United States–Mexico border.

Asociación de Hemato-Oncología Pediátrica de Centro América (AHOPCA): a model for sustainable development in pediatric oncology

Bridging the survival gap for children with cancer, between those (the great majority) in low and middle income countries (LMIC) and their economically advantaged counterparts, is a challenge that has been addressed by twinning institutions in high income countries with centers in LMIC. The long-established partnership between a Central American consortium--Asociación de Hemato-Oncología Pediátrica de Centro América (AHOPCA)--and institutions in Europe and North America provides a striking example of such a twinning program. The demonstrable success of this endeavor offers a model for improving the health outcomes of children with cancer worldwide. As this remarkable enterprise celebrates its 15th anniversary, it is appropriate to reflect on its origin, subsequent growth and development, and the lessons it provides for others embarking on or already engaged in similar journeys. Many challenges have been encountered and not all yet overcome. Commitment to the endeavor, collaboration in its achievements and determination to overcome obstacles collectively are the hallmarks that stamp AHOPCA as a particularly successful partnership in advancing pediatric oncology in the developing world.

AMOR II: an effort to eradicate psychosocial barriers induced by immigration phenomenon in children with cancer

BACKGROUND

Immigration in the childhood cancer population constitutes a stressor factor because of high biopsychosocial vulnerability. In recent years the incidence of immigrant children in our unit has increased. Since 2005 we have developed a psychosocial program to overcome this challenge. Our objective is to assess its impact on the immigrant pediatric population.

PROCEDURE

We have compared new cases (n=114) from 2005 to 2010 with historical cases (n=95) from 1995 to 2004. We administered a long-term follow-up questionnaire allowing for the assessment of symptoms associated with biopsychosocial variables.

RESULTS

Most of our immigrant patients came from Latin America and we observed a significant increase of cases coming from Morocco and Romania. The most common diagnosis was hematological malignancies. From 2005 to 2010 the disease status was mainly initial, whereas in the period 1995 to 2004 most of the patients arrived with advanced disease. Socioeconomic variables amongst these patients tended towards low incomes, high unemployment, and economic difficulties. The implementation of the biopsychosocial protocol AMOR II improved adaptation (P=0.012), the amount and understanding of information received (P=0.002), and family emotional support (P=0.004).

CONCLUSIONS

In brief, our biopsychosocial protocol had significantly increased some psychosocial variables. However, immigration in Spain is still associated with economic difficulties, "aculturism" and failure to adapt.

Paediatric cancer in low-income and middle-income countries

Patterns of cancer incidence across the world have undergone substantial changes as a result of industrialisation and economic development. However, the economies of most countries remain at an early or intermediate stage of development-these stages are characterised by poverty, too few health-care providers, weak health systems, and poor access to education, modern technology, and health care because of scattered rural populations. Low-income and middle-income countries also have younger populations and therefore a larger proportion of children with cancer than high-income countries. Most of these children die from the disease. Chronic infections, which remain the most common causes of disease-related death in all except high-income countries, can also be major risk factors for childhood cancer in poorer regions. We discuss childhood cancer in relation to global development and propose strategies that could result in improved survival. Education of the public, more and better-trained health professionals, strengthened cancer services, locally relevant research, regional hospital networks, international collaboration, and health insurance are all essential components of an enhanced model of care.

Scaling up cancer care for children without medical insurance in developing countries: The case of Mexico

BACKGROUND

In 2006, the Mexican government launched the Fund for Protection Against Catastrophic Expenditures (FPGC) to support financially healthcare of high cost illnesses. This study aimed at answering the question whether FPGC improved coverage for cancer care and to measure survival of FPGC affiliated children with cancer.

PROCEDURE

A retrospective cohort study (2006-2009) was conducted in 47 public hospitals. Information of children and adolescents with cancer was analyzed. The coverage was estimated in accordance with expected number of incident cases and those registered at FPGC. The survival was analyzed by using Kaplan-Meier survival curves and Cox proportional hazards regression modeling.

RESULTS

The study included 3,821 patients. From 2006 to 2009, coverage of new cancer cases increased from 3.3% to 55.3%. Principal diagnoses were acute lymphoblastic leukemia (ALL, 46.4%), central nervous system (CNS) tumors (8.2%), and acute myeloid leukemia (AML, 7.4%). The survival rates at 36 months were ALL (50%), AML (30.5%), Hodgkin lymphoma (74.5%), Non-Hodgkin lymphoma (40.1%), CNS tumors (32.8%), renal tumors (58.4%), bone tumors (33.4%), retinoblastoma (59.2%), and other solid tumors (52.6%). The 3-year overall survival rates varied among the regions; children between the east and south-southeast had the higher risks (hazard ratio 3.0; 95% CI: 2.3-3.9) and 2.4; 95% CI: 2.0-2.8) of death from disease when compared with those from the central region.

CONCLUSION

FPGC has increased coverage of cancer cases. Survival rates were different throughout the country. It is necessary to evaluate the effectiveness of this policy to increase access and identify opportunities to reduce the differences in survival.

Strategies to improve care for children with cancer in Sub-Saharan Africa

Great progress has been made in the care of children with cancer in recent decades. Worldwide, more than 80% of children with cancer live in resource-limited countries where access to care is poor. Sub-Saharan Africa is the world's poorest region. Child mortality is high, caused by largely preventable and treatable conditions. Paediatric cancer accounts for only a small fraction of deaths and understandably receives little attention from local policy makers or global health agencies. The survival of children with cancer is very poor. Challenges to improving survival include advanced-stage disease at presentation, failure to start or complete treatment (abandonment), inadequate hospital infrastructure and medications, lack of trained health care providers, lack of cancer registration and follow-up and lack of treatment guidelines adapted to local medical facilities. We propose a stepwise approach that integrates paediatric cancer treatment with existing general paediatric care. Priority is given to interventions (improvement of supportive care, diagnostic facilities) that also improve general paediatric care. Minimal requirements for diagnostic procedures include complete blood counts, HIV and malaria tests, blood cultures, histopathology and simple imaging (X-ray and ultrasonography). Feasible interventions include adequate palliative care, curative treatment for Burkitt lymphoma and Wilms tumour and symptomatic treatment for Kaposi sarcoma.

UK-based real-time lymphoproliferative disorder diagnostic service to improve the management of patients in Ghana

The objective of the study was to evaluate the feasibility of a UK-based real-time service to improve the diagnosis and management of lymphoproliferative disorders (LPDs) in Ghana. Adult patients reporting to hospital with a suspected LPD, during a 1 year period, were prospectively enrolled. Bone marrow and/or lymph node biopsies were posted to the Haematology Malignancy Diagnostic Service (HMDS), Leeds, UK and underwent morphological analysis and immunophenotyping. Results were returned by e-mail. The initial diagnoses made in Ghana were compared with the final HMDS diagnoses to assess the contribution of the HMDS diagnosis to management decisions. The study was conducted at the two teaching hospitals in Ghana—Komfo Anokye, Kumasi and Korle Bu, Accra. Participants comprised 150 adult patients (≥12 years old), 79 women, median age 46 years. Bone marrow and lymph node biopsy samples from all adults presenting with features suggestive of a LPD, at the two teaching hospitals in Ghana, over 1 year were posted to a UK LPD diagnostic centre, where immunophenotyping was performed by immunohistochemistry. Molecular analysis was performed where indicated. Diagnostic classifications were made according to international criteria. Final diagnosis was compared to the initial Ghanaian diagnosis to evaluate discrepancies; implications for alterations in treatment decisions were evaluated. Median time between taking samples and receiving e-mail results in Ghana was 15 days. Concordance between initial and final diagnoses was 32% (48 of 150). The HMDS diagnosis would have changed management in 31% (46 of 150) of patients. It is feasible to provide a UK-based service for LPD diagnosis in Africa using postal services and e-mail. This study confirmed findings from wealthy countries that a specialised haematopathology service can improve LPD diagnosis. This model of Ghana–UK collaboration provides a platform on which to build local capacity to operate an international quality diagnostic service for LPDs.

Malnutrition and neutropenia in children treated for Burkitt lymphoma in Malawi

BACKGROUND

Infection in neutropenic children is a major cause of morbidity and mortality in children treated for cancer. In developing countries, children with cancer are often malnourished at diagnosis. In Blantyre, Malawi, children with Burkitt lymphoma are treated with a local protocol with limited toxicity. The aim of this study was to evaluate the incidence and outcome of febrile neutropenia during this treatment and the association with malnutrition at diagnosis.

METHODS

We documented nutritional status, febrile and/or neutropenic episodes, antibiotic therapy and short term outcome of all children with Burkitt lymphoma treated according to the local protocol and admitted from January 2007 to March 2008.

RESULTS

Fifty eight (69%) of 84 patients were acutely malnourished at diagnosis with an arm muscle area (AMA) below the 5(th) percentile. Malnutrition at diagnosis was associated with a significantly higher rate of profound neutropenia. This association remained significant (OR 12; 95% C.I. 1.5 - infinitely; P = 0.012) after control for clinical stage of disease, bone marrow involvement and HIV infection which are possible confounders. All patients with profound neutropenia, prolonged neutropenia and treatment related deaths were malnourished at diagnosis. Four (4.9%) of 81 patients died of treatment related causes; three of them due to a Gram negative septicaemia.

CONCLUSION

Acute malnutrition at diagnosis is associated with significantly more treatment related profound neutropenia. The intensity of chemotherapeutic regimens has to be adapted to the level of available supportive care and patients' nutritional status and tolerance to avoid unacceptable morbidity and mortality. This local treatment protocol for Burkitt lymphoma has a treatment related mortality of 5% in patients in Malawi.

Baseline status of paediatric oncology care in ten low-income or mid-income countries receiving My Child Matters support: a descriptive study

BACKGROUND

Childhood-cancer survival is dismal in most low-income countries, but initiatives for treating paediatric cancer have substantially improved care in some of these countries. The My Child Matters programme was launched to fund projects aimed at controlling paediatric cancer in low-income and mid-income countries. We aimed to assess baseline status of paediatric cancer care in ten countries that were receiving support (Bangladesh, Egypt, Honduras, Morocco, the Philippines, Senegal, Tanzania, Ukraine, Venezuela, and Vietnam).

METHODS

Between Sept 5, 2005, and May 26, 2006, qualitative face-to-face interviews with clinicians, hospital managers, health officials, and other health-care professionals were done by a multidisciplinary public-health research company as a field survey. Estimates of expected numbers of patients with paediatric cancer from population-based data were used to project the number of current and future patients for comparison with survey-based data. 5-year survival was postulated on the basis of the findings of the interviews. Data from the field survey were statistically compared with demographic, health, and socioeconomic data from global health organisations. The main outcomes were to assess baseline status of paediatric cancer care in the countries and postulated 5-year survival.

FINDINGS

The baseline status of paediatric oncology care varied substantially between the surveyed countries. The number of patients reportedly receiving medical care (obtained from survey data) differed markedly from that predicted by population-based incidence data. Management of paediatric cancer and access to care were poor or deficient (ie, nonexistent, unavailable, or inconsistent access for most children with cancer) in seven of the ten countries surveyed, and accurate baseline data on incidence and outcome were very sparse. Postulated 5-year survival were: 5-10% in Bangladesh, the Philippines, Senegal, Tanzania, and Vietnam; 30% in Morocco; and 40-60% in Egypt, Honduras, Ukraine, and Venezuela. Postulated 5-year survival was directly proportional to several health indicators (per capita annual total health-care expenditure [Pearson's r(2)=0.760, p=0.001], per capita gross domestic product [r(2)=0.603, p=0.008], per capita gross national income [r(2)=0.572, p=0.011], number of physicians [r(2)=0.560, p=0.013] and nurses [r(2)=0.506, p=0.032] per 1000 population, and most significantly, annual government health-care expenditure per capita [r(2)=0.882, p<0.0001]).

INTERPRETATION

Detailed surveys can provide useful data for baseline assessment of the status of paediatric oncology, but cannot substitute for national cancer registration. Alliances between public, private, and international agencies might rapidly improve the outcome of children with cancer in these countries.

Treatment of children with acute lymphoblastic leukemia in India using a BFM protocol

BACKGROUND

Limited data exists on the long-term treatment outcome and prognosis of childhood ALL in India.

PROCEDURE

Three hundred and seven children (1-14 years) with acute lymphoblastic leukemia (ALL) were treated with a modified BFM protocol 76/79 between 1985 and 2003. Treatment outcome and prognostic factors were evaluated.

RESULTS

The median age was 6 years; 78% had B lineage acute lymphoblastic leukemia and 22% had T lineage disease. Good prednisolone response was observed in 82% of cases. Two hundred and seventy-three children (91.6%) achieved complete remission; with 2% induction-related mortality and 6.4% having resistant disease. 52% of all evaluable patients and 56.8% of complete responders are in continuous complete remission (CCR) at a median follow up of 62 months (30-194 months). The median event free survival (EFS) was 114 months. The estimated 5 year overall survival, EFS and disease free survival was 59.8%, 56%, and 53.9%, respectively. The prognostic factors adversely affecting the EFS were poor prednisolone response, resistant disease and WBC count greater than 20 x 10(9)/L at diagnosis. The 5 year EFS in the favorable risk group (age 1-9 years, WBC count less than 20 x 10(9)/L and prednisolone good response) was 73.1 +/- 4.9%.

CONCLUSION

This report examines a cohort of children with ALL treated with a BFM protocol in India with adequate follow up and demonstrates the need for cost effective improvements.

Absolute lymphocyte count is a novel prognostic indicator in ALL and AML: implications for risk stratification and future studies

BACKGROUND

Leukemia is the leading cause of disease-related death in children, despite significant improvement in survival and modern risk stratification. The prognostic significance of absolute lymphocyte counts (ALC) was evaluated in young patients with acute myeloblastic leukemia (AML) and acute lymphoblastic leukemia (ALL).

METHODS

In all, 171 consecutive de novo cases of AML and ALL, age <or=21 years, were analyzed. Age, initial white blood cell count, cytogenetics, and bone marrow response were compared with lymphocyte, neutrophil, and platelet counts at weekly intervals during induction chemotherapy.

RESULTS

ALC is a significant independent predictor of relapse and survival. For example, in patients with AML an ALC on Day 28 of induction (ALC-28) <350 cells/microL predicts very poor survival, with a 5-year relapse-free survival (RFS) of only 10% (hazard ratio [HR] 3.7, P= .003). In contrast, an ALC-15 >350 cells/microL carries an excellent prognosis, with a 5-year overall survival (OS) of 85% (HR 0.2, P= .012). Similarly in ALL, an ALC-15 <350 cells/microL predicts poor survival, with a 6-year RFS of 43% (HR 4.5, P= .002), whereas an ALC-15 >350 cells/microL predicts excellent outcome, with a 6-year OS of 87% (HR 0.2, P= .018). Importantly, ALC remains a strong predictor in multivariate analysis with known prognostic factors.

CONCLUSIONS

ALC is a simple, statistically powerful measurement for patients with de novo AML and ALL. The results, when combined with previous studies, demonstrate that ALC is a powerful new prognostic factor for a range of malignancies. These findings suggest a need for further exploration of postchemotherapy immune status and immune-modulating cancer therapies.

Implementation of a data management program in a pediatric cancer unit in a low income country

INTRODUCTION

Pediatric cancer units in low-income countries lack data on which to base quality improvement initiatives. We implemented a data management program in the oncology unit of the children's hospital of Tegucigalpa, Honduras, and then we assessed training and supervision of data managers, data accuracy, and completeness as well as obstacles encountered.

METHODS

Training included 2 days of off-site hands-on instruction in the use of an online database, daily on-site supervision by physicians, periodic online meetings for education and problem-solving, and continuous e-mail support.

RESULTS

Of the 652 patients diagnosed with acute leukemia between July 1995 and June 2005, 150 (23%) had not yet been registered in the database at the time of audit and 65 (10%) had missing medical records. The remaining 437 charts (67%) were reviewed by an external auditor and compared to the data entered previously by the two trained data managers. Protocol information was incomplete in 30% of cases, and the cause of death was inaccurate in 18%. All other data were 99% accurate and 93%-100% complete. Obstacles included a limited medical records system, poor organization of the charts, missing records, inconsistently documented protocol information, data managers who lack a medical background, and slow or unreliable internet connections.

CONCLUSION

Data managers can be trained to effectively collect basic pediatric oncology data in a low-income country. Addressing inadequacies in the medical record system while providing specific training in protocol-based care and determination of cause of death for both physicians and data managers will improve data quality.
