Using prospective methods to identify fieldwork locations favourable to understand divergences in health care accessibility

Central to this article is the issue of choosing sites for where a fieldwork could provide a better understanding of divergences in health care accessibility. Access to health care is critical to good health, but inhabitants may experience barriers to health care limiting their ability to obtain the care they need. Most inhabitants of low-income countries need to walk long distances along meandering paths to get to health care services. Individuals in Malawi responded to a survey with a battery of questions on perceived difficulties in accessing health care services. Using both vertical and horizontal impedance, we modelled walking time between household locations for the individuals in our sample and the health care centres they were using. The digital elevation model and Tobler’s hiking function were used to represent vertical impedance, while OpenStreetMap integrated with land cover map were used to represent horizontal impedance. Combining measures of walking time and perceived accessibility in Malawi, we used spatial statistics and found spatial clusters with substantial discrepancies in health care accessibility, which represented fieldwork locations favourable for providing a better understanding of barriers to health access.publishedVersio

Access to assistive technology in two Southern African countries

Background Millions of people in Southern Africa are deprived of basic human rights such as the right to education and work because of the large and growing unmet demand for assistive technologies (AT). Evidence is needed to better characterize the lack of AT access. Methods This study serves to identify the sociodemographic factors that are associated with access to AT in two countries in Southern Africa, Botswana and Swaziland. To achieve this aim, logistics regression was applied to a subset of variables from two Living Conditions Studies, nationally representative surveys that were conducted in Southern Africa (2014 and 2010). Results In Botswana, 44% of people who needed AT did not receive it, while in Swaziland the unmet need was 67%. Among the sociodemographic variables tested, the type of disability was the most important factor in determining AT access in both countries. The likelihood of AT access was highest in both countries for those who had mobility limitations (i.e., difficulty walking/climbing stairs) [Botswana: 6.4 odds ratio (OR) = 6.4., 95% confidence internal (CI) (3.6–11.3); Swaziland: OR = 3.2, CI (1.4–7.3)], in comparison to those with non-mobility types of disabilities. Conclusions These findings provide support for governments and other stakeholders in the AT sector to prioritize AT to address the large unmet demand, and expand the range of AT products provided so that people with hearing, seeing, self-care, communication and cognition difficulties have equal access to AT as those with mobility impairments. A step toward achieving these aims is to inventory AT product types that are commonly covered through the public sector in each country, and identify common gaps (e.g., daily living aids). Advancing the AT sector as a whole within Southern Africa will require large scale qualitative studies that achieve a comprehensive understanding of the bottlenecks in regional AT supply, procurement, and delivery systems

Perceptions and satisfaction of caregivers regarding rehabilitation services from selected rehabilitation centres in the Western Cape

BACKGROUND: Understanding caregivers’ views on rehabilitation services is important as it may assist in informing healthcare services and patient management. OBJECTIVES: The aim of this study was to explore caregivers’ perceptions and satisfaction regarding rehabilitation services in the Western Cape, South Africa, and to inform clinical practice and policy in this emerging field. METHOD: This study used a descriptive, qualitative design using in-depth interviews with conveniently selected participants. Interviews were conducted with 13 caregivers of patients with: amputations (3), cerebrovascular accidents (5) and neuromuscular disorders (5). Thematic content analysis was conducted with the transcripts. RESULTS: Four key themes emerged, which were (1) financial difficulties, (2) caregiver and therapist relationships, (3) facility management and (4) caregiver experience with service delivery. CONCLUSION: Based on the participants’ feedback, the rehabilitation services seem to be meeting the basic rehabilitation needs of the patients; however, the needs of the caregivers require attention

Perceived current needs, psychological distress and functional impairment in a war-affected setting: a cross-sectional study in South Sudan

Objectives To examine the current perceived needs of the general population in a war-affected setting, and to study the influence of perceived needs on the participants’ mental health status and functional impairment across genders. Methods A cross-sectional community survey (n=464) was conducted in war-affected South Sudan. Three regression models were analysed. Perceived needs were assessed with the Humanitarian Emergency Settings Perceived Needs Scale. Psychological distress was measured with the General Health Questionnaire and level of functioning by the Short Form Health Survey (SF-12). Results The most frequently expressed needs were related to drinking water, alcohol and drug use in the community and access to sanitation facilities. No gender differences were found regarding the level of perceived needs or the number of traumatic events. Higher level of perceived needs significantly predicted psychological distress and lower level of functioning even when numbers of experienced trauma events were taken into account. Conclusions The associations of higher level of needs and trauma experiences, on the one hand, and negative health outcomes on the other, necessitate a greater integration of interventions directed towards the population's perceived needs and mental health, particularly for those who have been exposed to trauma

How representative are organisations of persons with disabilities? Data from nine population-based surveys in low- and middle-income countries

Organisations of Persons with Disabilities (OPDs) are critical to promoting and protecting the rights of people with disabilities. However, little is known about the extent to which people with disabilities are aware and members of OPDs. This study uses data from nine population-based surveys in low- and middle-income countries to explore OPD awareness and membership. Across settings, about a third of people with disabilities were aware of OPDs and fewer than 15% were members. Awareness and membership were lower amongst older adults, women, people with difficulties communicating, remembering and with self-care, people with less education, in poverty and in rural areas. Underrepresentation of certain groups may indicate a need to seek out the voices of people less likely to be associated with OPDs. Further, low total membership may be a cause for concern in settings where OPDs are relied upon to deliver essential services in the absence of state structures

Pancreatobiliary versus intestinal histologic type of differentiation is an independent prognostic factor in resected periampullary adenocarcinoma

<p>Abstract</p> <p>Background</p> <p>Resectable adenocarcinomas in the pancreatic head, by definition "periampullary", originate from ampullary, duodenal, biliary, or ductal pancreatic epithelium. Typically, periampullary adenocarcinomas have either intestinal or pancreatobiliary type of differentiation, and the type of differentiation might be prognostically more important than the anatomic site of origin. The aim of the study was to determine whether the histologic type of differentiation is an independent prognostic factor in periampullary adenocarcinoma, and whether tumour origin predicts the prognosis in pancreatobiliary type carcinomas independently of resection margin involvement, tumour size, nodal involvement, perineural and vascular infiltration, and degree of differentiation.</p> <p>Methods</p> <p>Histopathologic variables in 114 consecutively resected periampullary adenocarcinomas of pancreatobiliary (n = 67) and intestinal (n = 47) type differentiation were evaluated using a standardized, systematic protocol for evaluation of the resected specimen (study group). Histologic type of differentiation and tumour origin were compared as predictors of survival, and the results were validated by comparison with a historical control group consisting of 99 consecutive pancreaticoduodenectomies performed before standardization of histopathologic evaluation. Associations between histopathologic variables were evaluated by Chi-square and Mann-Whitney tests. Survival was estimated by the Kaplan-Meier method, comparing curves using log-rank test, and by univariate and multivariable Cox regression analysis.</p> <p>Results</p> <p>Both in the study group (n = 114) and in the historical control group (n = 99), the histologic type of differentiation independently predicted survival, while tumour origin predicted survival only in univariate analysis. Independent adverse predictors of survival in the study group were pancreatobiliary type differentiation (p < 0.001; HR 3.1; CI 1.8–5.1), regional lymph node involvement (p < 0.001; HR 2.5; CI 1.5–4.4), vessel involvement (p = 0.012; HR 1.9; CI 1.2–3.1), and increasing tumour diameter (measured in cm, p = 0.011; HR 1.3; CI 1.1–1.5). For pancreatobiliary differentiated adenocarcinomas (n = 67), lymph node status, vessel involvement, and tumour diameter remained independent prognostic factors, while tumour origin did not independently predict the prognosis due to significant association with tumour size (p < 0.001) and lymph node involvement (p = 0.004).</p> <p>Conclusion</p> <p>Pancreatobiliary versus intestinal type of differentiation independently predicts poor prognosis after pancreaticoduodenectomy for periampullary adenocarcinoma. Lymph node involvement, vessel infiltration, and increasing tumour diameter are adverse predictors of survival in tumours with pancreatobiliary differentiation.</p

Resectable adenocarcinomas in the pancreatic head: the retroperitoneal resection margin is an independent prognostic factor

Pancreatic cancer is a lethal disease, and even after assumed margin-free pancreatoduodenectomy, most patients die within few years. The aims were to evaluate the importance of standardised histopathologic assessment for adequacy of reporting and survival estimates, and to report on prognostic factors in a setting of standardised histopathologic assessment. We performed immunohistochemical evaluation, slide review, and review of histopathologic reports from all pancreatoduodenectomies at Rikshospitalet University Hospital in 1980–2004. Reports from 1998-2004 at this institution were compared with reports from all other Norwegian institutions in the same period. Standardised histopathologic assessment and reporting was found necessary to avoid underestimation of poor prognostic factors, and to avoid misdiagnosis of tumours originating from non-pancreatic tissue (ampulla, distal bile duct, duodenum). Standardised histopathology was more important than surgical volume for completeness of reporting and for reliability of survival estimates, particularly with respect to lymph node evaluation. Immunostaining for MUC1 and MUC4 identified a subgroup of patients with particularly poor prognosis. Standardised histopathologic evaluation should be a first prerequisite to assure adequate histopathology after pancreatoduodenectomy. Immunostaining may identify tumour markers potentially targetable in future adjuvant treatments for pancreatic cancer

Disability and poverty – Reflections on research experiences in Africa and beyond

Background: Whilst broadly agreed in the literature that disability and poverty are closely interlinked, the empirical basis for this knowledge is relatively weak. Objectives: To describe and discuss the current state of knowledge and to suggest the need for further generation of knowledge on disability and poverty. Method: Two recent attempts at statistically analysing the situation for disabled people and a series of qualitative studies on disability and poverty are applied in a discussion on the state of current knowledge. Results: Firstly, the surveys confirm substantial gaps in access to services, and a systematic pattern of lower levels of living amongst individuals with disability as compared to non-disabled. Existing surveys are however not originally set up to study the disability – poverty relationship and thus have some important limitations. Secondly, the qualitative studies have shown the relevance of cultural, political and structural phenomena in relation to poverty and disability, but also the complexity and the contextual character of these forces that may sometimes provide or create opportunities either at the individual or the collective level. Whilst not establishing evidence as such, the qualitative studies contribute to illustrating some of the mechanisms that bring individuals with disability into poverty and keep them there. Conclusions: A longitudinal design including both quantitative and qualitative methods and based on the current conceptual understanding of both disability and poverty is suggested to pursue further knowledge generation on the relationship between disability and poverty

Development process in Africa: Poverty, politics and indigenous knowledge

Background: Persons with disability run the danger of not profiting from the development process due to exclusion from basic services and opportunities. Still, the knowledge base on exclusion mechanisms is relatively weak and there is a danger that important aspects are not addressed as they are hidden behind established understandings that are not critically scrutinised. Objectives: The main purpose of this article was to highlight critical thoughts on prevailing knowledge of the relationship between disability and poverty, the policy base for addressing the rights of persons with disability, and culture as a key component in continued discrimination. Method: This article aimed at integrating three papers on the above topics presented at the 2011 African Network for Evidence-to-Action on Disability (AfriNEAD) Symposium. The researchers have therefore thoroughly examined and questioned the relationship between disability and poverty, the influence of policy on action, and the role of culture in reproducing injustice. Results: The article firstly claims that there are limitations in current data collection practice with regards to analysing the relationship between poverty and disability. Secondly, ambitions regarding inclusion of persons with disability in policy processes as well as in implementation of policies are not necessarily implemented in an optimal way. Thirdly, negative aspects of culture in discrimination and bad treatment of disabled need to be highlighted to balance the discussion on disability and culture. Conclusion: A critical view of prevailing understandings of disability and development is key to producing the knowledge necessary to eradicate poverty amongst persons with disability and other vulnerable groups. Not only do we need research that is actually designed to reveal the mechanisms behind the disability–poverty relationship, we need research that is less tied up with broad political agreements that is not necessarily reflecting the realities at ground level
