The pattern of symptoms in patients receiving home based care in Bangwe, Malawi : a descriptive study

Abstract Background Home based care of HIV/AIDS patients is a health need recommended but not often available in Africa. Population based assessment helps to identify unmet health needs to plan services. Careful assessment and follow up of patients receiving home based care in a defined population of Bangwe, Malawi provides details of the frequency and severity of common symptoms. Methods Mortality and the incidence, duration and severity of common symptoms of patients in a defined population receiving home based care were measured over an eighteen month period. Results 358 patients, of whom 199 died, were studied. A third of patients died within 4 months of being first seen. About half the patients were unable to care for themselves on first assessment. Half were malnourished with a Body Mass Index (BMI) &lt; 18.5 kg/m2. Most patients had a mixture of symptoms at presentation. These symptoms responded to treatment usually within a fortnight. However a small proportion (5%) of patients suffered repeated episodes often as many as 6–9 times a year. Incidence rates are estimated. Conclusion Symptoms which are alleviated by simple treatments are common. The patients in whom symptoms recur need a responsive home based care service. Population based estimates of incidence and duration of disease and the visit work load allow an assessment of home based care needs in an urban setting in Africa. </jats:sec

Robotic path-planning through dynamic maps

Robotic global navigation is often based on the assumption that the world is static. It assumes that obstacles present in maps will be there later and new obstacles will be dealt with by a local planning algorithm. When robots interact in an environment inhabited by people, this assumption does not hold. People add dynamism to the world and, in order for robots to deal with this properly, these changes must be addressed. This project explores possible methods for representing dynamism in Robot Operating System (ROS) navigation software and methods for robots to navigate with this new information. It presents an adaptation of ROS software to handle the added complexity and compares the results of dynamic map-based navigation with traditional approaches. The results of this analysis find benefits in plan quality and indicate that the topic is deserving of further study. As this is a broad topic, many new areas for future work were uncovered that would allow full integration of this representation with existing ROS software

Using a community of practice to evaluate falls prevention activity in a residential aged care organisation: a clinical audit

Objective This study evaluates whether a community of practice (CoP) could conduct a falls prevention clinical audit and identify gaps in falls prevention practice requiring action. Methods Cross-sectional falls prevention clinical audits were conducted in 13 residential aged care (RAC) sites of a not-for-profit organisation providing care to a total of 779 residents. The audits were led by an operationalised CoP assisted by site clinical staff. A CoP is a group of people with a shared interest who get together to innovate for change. The CoP was made up of self-nominated staff representing all RAC sites and comprised of staff from various disciplines with a shared interest in falls prevention. Results All 13 (100%) sites completed the audit. CoP conduct of the audit met identified criteria for an effective clinical audit. The priorities for improvement were identified as increasing the proportion of residents receiving vitamin D supplementation (mean 41.5%, s.d. 23.7) and development of mandatory falls prevention education for staff and a falls prevention policy, as neither was in place at any site. CoP actions undertaken included a letter to visiting GPs requesting support for vitamin D prescription, surveys of care staff and residents to inform falls education development, defining falls and writing a falls prevention policy. Conclusion A CoP was able to effectively conduct an evidence-based falls prevention activity audit and identify gaps in practice. CoP members were well positioned, as site staff, to overcome barriers and facilitate action in falls prevention practice

Measuring and managing the work environment of the mid-level provider – the neglected human resource

BACKGROUND: Much has been written in the past decade about the health workforce crisis that is crippling health service delivery in many middle-income and low-income countries. Countries having lost most of their highly qualified health care professionals to migration increasingly rely on mid-level providers as the mainstay for health services delivery. Mid-level providers are health workers who perform tasks conventionally associated with more highly trained and internationally mobile workers. Their training usually has lower entry requirements and is for shorter periods (usually two to four years). Our study aimed to explore a neglected but crucial aspect of human resources for health in Africa: the provision of a work environment that will promote motivation and performance of mid-level providers. This paper explores the work environment of mid-level providers in Malawi, and contributes to the validation of an instrument to measure the work environment of mid-level providers in low-income countries. METHODS: Three districts were purposively sampled from each of the three geographical regions in Malawi. A total of 34 health facilities from the three districts were included in the study. All staff in each of the facilities were included in the sampling frame. A total of 153 staff members consented to be interviewed. Participants completed measures of perceptions of work environment, burnout and job satisfaction. FINDINGS: The Healthcare Provider Work Index, derived through Principal Components Analysis and Rasch Analysis of our modification of an existing questionnaire, constituted four subscales, measuring: (1) levels of staffing and resources; (2) management support; (3) workplace relationships; and (4) control over practice. Multivariate analysis indicated that scores on the Work Index significantly predicted key variables concerning motivation and attrition such as emotional exhaustion, job satisfaction, satisfaction with the profession and plans to leave the current post within 12 months. Additionally, the findings show that mid-level medical staff (i.e. clinical officers and medical assistants) are significantly less satisfied than mid-level nurses (i.e. enrolled nurses) with their work environments, particularly their workplace relationships. They also experience significantly greater levels of dissatisfaction with their jobs and with their profession. CONCLUSION: The Healthcare Provider Work Index identifies factors salient to improving job satisfaction and work performance among mid-level cadres in resource-poor settings. The extent to which these results can be generalized beyond the current sample must be established. The poor motivational environment in which clinical officers and medical assistants work in comparison to that of nurses is of concern, as these staff members are increasingly being asked to take on leadership roles and greater levels of clinical responsibility. More research on mid-level providers is needed, as they are the mainstay of health service delivery in many low-income countries. This paper contributes to a methodology for exploring the work environment of mid-level providers in low-income countries and identifies several areas needing further research

Barriers and attitudes influencing non-engagement in a peer feedback model to inform evidence for GP appraisal

<p>Abstract</p> <p>Background</p> <p>The UK general practitioner (GP) appraisal system is deemed to be an inadequate source of performance evidence to inform a future medical revalidation process. A long-running voluntary model of external peer review in the west of Scotland provides feedback by trained peers on the standard of GP colleagues' core appraisal activities and may 'add value' in strengthening the robustness of the current system in support of revalidation. A significant minority of GPs has participated in the peer feedback model, but a clear majority has yet to engage with it. We aimed to explore the views of non-participants to identify barriers to engagement and attitudes to external peer review as a means to inform the current appraisal system.</p> <p>Methods</p> <p>We conducted semi-structured interviews with a sample of west of Scotland GPs who had yet to participate in the peer review model. A thematic analysis of the interview transcriptions was conducted using a constant comparative approach.</p> <p>Results</p> <p>13 GPs were interviewed of whom nine were males. Four core themes were identified in relation to the perceived and experienced 'value' placed on the topics discussed and their relevance to routine clinical practice and professional appraisal: 1. Value of the appraisal improvement activity. 2. Value of external peer review. 3. Value of the external peer review model and host organisation and 4. Attitudes to external peer review.</p> <p>Conclusions</p> <p>GPs in this study questioned the 'value' of participation in the external peer review model and the national appraisal system over the standard of internal feedback received from immediate work colleagues. There was a limited understanding of the concept, context and purpose of external peer review and some distrust of the host educational provider. Future engagement with the model by these GPs is likely to be influenced by policy to improve the standard of appraisal and contractual related activities, rather than a self-directed recognition of learning needs.</p

Selecting HIV infection prevention interventions in the mature HIV epidemic in Malawi using the mode of transmission model

<p>Abstract</p> <p>Background</p> <p>Malawi is reassessing its HIV prevention strategy in the light of a limited reduction in the epidemic. No community based incidence studies have been carried out in Malawi, so estimates of where new infections are occurring require the use of mathematical models and knowledge of the size and sexual behaviour of different groups. The results can help to choose where HIV prevention interventions are most needed.</p> <p>Methods</p> <p>The UNAIDS Mode of Transmission model was populated with Malawi data and estimates of incident cases calculated for each exposure group. Scenarios of single and multiple interventions of varying success were used to identify those interventions most likely to reduce incident cases.</p> <p>Results</p> <p>The groups accounting for most new infections were the low-risk heterosexual group - the discordant couples (37%) and those who had casual sex and their partners (a further 16% and 27% respectively) of new cases.</p> <p>Circumcision, condoms with casual sex and bar girls and improved STI treatment had limited effect in reducing incident cases, while condom use with discordant couples, abstinence and a zero-grazing campaign had major effects. The combination of a successful strategy to eliminate multiple concurrent partners and a successful strategy to eliminate all infections between discordant couples would reduce incident cases by 99%.</p> <p>Conclusions</p> <p>A revitalised HIV prevention strategy will need to include interventions which tackle the two modes of transmission now found to be so important in Malawi - <b>concurrency and discordancy</b>.</p
