Data Challenges in Addressing Chronic Kidney Disease in Low- and Lower-Middle-Income Countries.

ABSTRACT: The burden of chronic kidney disease (CKD) is growing globally, particularly in low- and lower-middle-income countries (LLMICs) where access to treatment is poor and the largest increases in disease burden will occur. The individual and societal costs of kidney disease are well recognized, especially in developed health care systems where treatments for the advanced stages of CKD are more readily available. The consequences of CKD are potentially more catastrophic in developing health care systems where such resources are often lacking. Central to addressing this challenge is the availability of data to understand disease burden and ensure that investments in treatments and health resources are effective at a local level. Use of routinely collected administrative data is helpful in this regard, however, the barriers to developing a more systematic focus on data collection should not be underestimated. This article reviews the current tools that have been used to measure the burden of CKD and considers limitations regarding their use in LLMICs. A review of the literature investigating the use of registries, disease specific databases and administrative data to identify populations with CKD in LLMICs, which indicate these to be underused resources, is included. Suggestions regarding the potential use of administrative data for measuring CKD burden in LLMICs are explored.

Project description:An estimated 23 million infants are still not being benefitted from routine immunization services. We assessed how many children failed to be fully immunized even though they or their mothers were in contact with health services to receive other interventions.Fourteen countries with Demographic and Health Surveys and Multiple Indicator Cluster Surveys carried out after 2000 and with coverage for DPT (Diphtheria-tetanus-pertussis) vaccine below 70% were selected. We defined full immunization coverage (FIC) as having received one dose of BCG (bacille Calmette-Guérin), one dose of measles, three doses of polio, and three doses of DPT vaccines. We tabulated FIC against: antenatal care (ANC), skilled birth attendance (SBA), postnatal care for the mother (PNC), vitamin A supplementation (VitA) for the child, and sleeping under an insecticide-treated bed-net (ITN). Missed opportunities were defined as the percentage of children who failed to be fully immunized among those receiving one or more other interventions.Children who received other health interventions were also more likely to be fully immunized. In nearly all countries, FIC was lowest among children born to mothers who failed to attend ANC, and highest when the mother had four or more ANC visits Côte d'Ivoire presented the largest difference in FIC: 54 percentage points (pp) between having four or more ANC visits and lack of ANC. SBA was also related with higher FIC. For instance, the coverage in children without SBA was 36 pp lower than for those with SBA in Nigeria. The largest absolute difference on FIC in relation to PNC was observed for Ethiopia: 31 pp between those without and with PNC. FIC was also positively related with having received VitA. The largest absolute difference was observed in DR Congo: 41 pp. The differences in FIC among whether or not children slept under ITN were much smaller than for other interventions. Haiti presented the largest absolute difference: 16 pp.Our results show the need to develop and implement strategies to vaccinate all children who contact health services in order to receive other interventions.

Project description:BackgroundDelays to cancer diagnosis exist, resulting in worse survival outcomes for many cancers. Interventions targeting delays and barriers to cancer diagnosis and treatment have been investigated, but mostly in high-income countries. We conducted a systematic literature review to identify and characterize the interventions studied across cancers, within low- and middle-income countries (LMICs).MethodsThis systematic review forms part two of a wider study examining solutions to delays and barriers in cancer early diagnosis in LMICs. A comprehensive literature search was conducted on November 27, 2017, encompassing published studies from the preceding 15 years. We extracted study design, population, and intervention, and reported outcome measures from each study. Results were presented by target of interventions (general vs. health care professionals). A narrative synthesis was used to summarize intervention efficacy.ResultsOf 10,193 abstracts returned, 25 were included, consisting of studies across World Health Organization geographical regions, examining breast, cervix, childhood, prostate, head and neck, and gastric cancers. Altogether, 11 intervention studies targeted the general population, 12 targeted health care professionals, and 2 targeted both. The majority (17/25) of studies reported interventions focusing on patient and diagnosis-related barriers early in the cancer care pathway. Most studies reported knowledge score as primary outcome measure (17/25); few (6/25) reported on clinically relevant measures such as reducing disease stage at presentation or diagnostic time interval. Effectiveness of interventions was demonstrated for some cancers only.ConclusionMore interventions reporting clinically relevant measures and using standardized methods and outcomes are required to improve our ability to effectively improve cancer early diagnosis in LMICs.Implications for practicePrior to this study, the extent of intervention literature in cancer early diagnosis in low- and middle-income countries had not been characterized. This study aimed to outline and characterize interventions across all cancer types and across all countries. This systematic review demonstrated that interventions have been investigated targeting both the general population and health care professionals. Furthermore, this review demonstrates that the majority of studies report knowledge as an outcome measure, rather than clinically significant measures that improve cancer-related outcomes, such as delay intervals or downstaging of disease. Future interventions should address clinically relevant measures to better assess efficacy of interventions.
