Evaluation of a surgical training programme for clinical officers in Malawi.

BACKGROUND: Shortages of specialist surgeons in African countries mean that the needs of rural populations go unmet. Task-shifting from surgical specialists to other cadres of clinicians occurs in some countries, but without widespread acceptance. Clinical Officer Surgical Training in Africa (COST-Africa) developed and implemented BSc surgical training for clinical officers in Malawi. METHODS: Trainees participated in the COST-Africa BSc training programme between 2013 and 2016. This prospective study done in 16 hospitals compared crude numbers of selected numbers of major surgical procedures between intervention and control sites before and after the intervention. Volume and outcomes of surgery were compared within intervention hospitals between the COST-Africa trainees and other surgically active cadres. RESULTS: Seventeen trainees participated in the COST-Africa BSc training. The volume of surgical procedures undertaken at intervention hospitals almost doubled between 2013 and 2015 (+74 per cent), and there was a slight reduction in the number of procedures done in the control hospitals (-4 per cent) (P = 0·059). In the intervention hospitals, general surgery procedures were more often undertaken by COST-Africa trainees (61·2 per cent) than other clinical officers (31·3 per cent) and medical doctors (7·4 per cent). There was no significant difference in postoperative wound infection rates for hernia procedures at intervention hospitals between trainees and medical doctors (P = 0·065). CONCLUSION: The COST-Africa study demonstrated that in-service training of practising clinical officers can improve the surgical productivity of district-level hospitals.

'A melting pot of cultures' -challenges in social adaptation and interactions amongst international medical students.

BACKGROUND: The internationalisation of higher level education and the profiles - nationalities, ethnicities and cultural identities - of students who migrate to undertake higher level education programmes in a different country are increasingly complex. This article explores the way in which cultural backgrounds impact the student's experiences of an international medical school, and how these experiences have the potential to inform the development and design of student support services for those students who are not coping well with the transition. METHODS: Thirty one first year students were interviewed by sixteen second year students who were trained and supervised by an experienced researcher. Three focus group discussions were also held. RESULTS: While many international students had lived in more than one country and region and spoke several languages, most reported difficulties in forming intercultural friendships, especially interactions outside of the academic setting. Some of the challenges faced were similar to what has been reported in the literature, such as difficulties with language and loss of established friendship networks. Other challenges to emerge in this study were the complex interrelatedness of the daily life challenges facing international students regarding the forming and importance of intercultural relations, which is impacted by gender, the presence of alcohol, languages spoken (in addition to English, which was the language used for medical education), and the dominance of the regional grouping the student belongs to. CONCLUSION: The challenges of adaptation and intercultural relations are increasing in complexity and it is important for higher level institutions who enrol international students to understand the nature of the pressures these students experience, outside as well as within the academic environment, and to support them in managing these transitions.

'I think we are going to leave these cases'. Obstacles to surgery in rural Malawi: a qualitative study of provider perspectives.

OBJECTIVES: Surgical services at district level in Malawi are poor, yet the majority of the population resides in rural areas. This study aimed to explore the perceived obstacles to surgery from the perspective of the cadre directly responsible for surgical service delivery at district hospitals. METHODS: Qualitative interviews were conducted with 16 clinical officers (COs) receiving surgical training in eight public district hospitals and their 12 trainers. Thematic analysis of data was conducted using a top-down coding method. RESULTS: Despite readiness of the COs to conduct operations, other staff essential for surgery were sometimes unavailable to support them. Respondents attributed this to lack of skills, weak motivation or poor work ethic of their colleagues. Lack of commitment to do surgery, passiveness, lack of initiative in problem-solving and 'laziness' of surgical team members were among the reasons provided by study participants, accounting for unnecessary cancellations of elective surgery and inappropriate referrals of emergency cases. Other factors included infrastructure breakdowns and stock-outs of surgical supplies. There were instances where COs, and their supervisors, showed initiative in finding solutions to problems resulting from poor district hospital management practices. CONCLUSIONS: This study demonstrates how the motivation of surgical team members is a key factor in deciding whether or not to perform operations; and that shortages of supplies or infrastructure need not be an absolute obstacle to service delivery. Scale-up of surgical services at district level requires investments to improve surgical and anaesthetic skills, to strengthen human resources and facility management, and to ensure the availability of reliable infrastructure and essential supplies.

The use of technology enhanced learning in health research capacity development: lessons from a cross country research partnership.

BACKGROUND: With the recognition of the need for research capacity strengthening for advancing health and development, this research capacity article explores the use of technology enhanced learning in the delivery of a collaborative postgraduate blended Master's degree in Malawi. Two research questions are addressed: (i) Can technology enhanced learning be used to develop health research capacity?, and: (ii) How can learning content be designed that is transferrable across different contexts? METHODS: An explanatory sequential mixed methods design was adopted for the evaluation of technology enhanced learning in the Masters programme. A number of online surveys were administered, student participation in online activities monitored and an independent evaluation of the programme conducted. RESULTS: Remote collaboration and engagement are paramount in the design of a blended learning programme and support was needed for selecting the most appropriate technical tools. Internet access proved problematic despite developing the content around low bandwidth availability and training was required for students and teachers/trainers on the tools used. Varying degrees of engagement with the tools used was recorded, and the support of a learning technologist was needed to navigate through challenges faced. CONCLUSION: Capacity can be built in health research through blended learning programmes. In relation to transferability, the support required institutionally for technology enhanced learning needs to be conceptualised differently from support for face-to-face teaching. Additionally, differences in pedagogical approaches and styles between institutions, as well as existing social norms and values around communication, need to be embedded in the content development if the material is to be used beyond the pilot resource-intensive phase of a project.

Respiratory tract dendritic cells in paediatric asthma.

BACKGROUND: Airway dendritic cells (DC) are critical mediators of lung inflammation in asthma, but the characteristics of DC in the airways of healthy children, and children with asthma, are currently unknown. OBJECTIVE: We sought to identify changes in DC subset distribution and activation profile in paediatric asthma using flow cytometry to analyse induced sputum samples obtained from healthy and asthmatic children. METHODS: Lung function and atopic status were determined by spirometry and skin prick testing. Induced sputum samples were analysed using 7-colour flow cytometry to identify airway DC populations (lineage(-) HLA-DR(+) sputum cells expressing either CD11c as conventional DC or CD123 as plasmacytoid DC). RESULTS: Sputum samples containing lower airway plugs were obtained from 10 healthy children and 8 children with asthma. Lineage(-) HLA-DR(+) DC were successfully identified in all samples, and DC comprised a significantly higher proportion of sputum cells in children with asthma compared with age-matched healthy controls (1.29% vs. 0.67%, P = 0.02). DC expression of the costimulatory marker CD86 was significantly reduced in asthmatic children (73.4% vs. 59.7%, P = 0.04). Sputum DC also included numerous CD1c(+) cells (mean 57% of the total DC population) and low frequencies of cells expressing the subset markers CD141 or CD123, although the proportions of these did not differ between groups. CONCLUSIONS: Airway DC can be identified and characterized non-invasively using flow cytometry to analyse paediatric sputum samples. Our data reveal that children with steroid-treated asthma exhibit increased frequency of airway DC with reduced expression of the costimulatory marker CD86, suggesting altered trafficking and/or maturation of these cells either due to asthma or steroid therapies.

International students' experience of a western medical school: a mixed methods study exploring the early years in the context of cultural and social adjustment compared to students from the host country.

BACKGROUND: Few studies have addressed the challenges associated with international students as they adapt to studying medicine in a new host country. Higher level institutions have increasing numbers of international students commencing programmes. This paper explores the experiences of a cohort of students in the early years of medical school in Ireland, where a considerable cohort are from an international background. METHODS: A mixed exploratory sequential study design was carried out with medical students in the preclinical component of a five year undergraduate programme. Data for the qualitative phase was collected through 29 semi-structured interviews using the peer interview method. Thematic analysis from this phase was incorporated to develop an online questionnaire combined with components of the Student Adaptation to College Questionnaire and Student Integration Questionnaire. First year students were anonymously surveyed online. The Mokken Scaling procedure was used to investigate the students' experiences, both positive and negative. RESULTS: Three main themes are identified; social adjustment, social alienation and cultural alienation. The response rate for the survey was 49% (467 Respondents). The Mokken Scaling method identified the following scales (i) Positive experience of student life; (ii) Social alienation, which comprised of negative items about feeling lonely, not fitting in, being homesick and (iii) Cultural alienation, which included the items of being uncomfortable around cultural norms of dress and contact between the sexes. With the threshold set to H = 0.4. Subscales of the positive experiences of student life scale are explored further. CONCLUSIONS: Overall student adjustment to a western third level college was good. Students from regions where cultural distance is greatest reported more difficulties in adjusting. Students from these regions also demonstrate very good adaptation. Some students from the host country and more similar cultural backgrounds were also struggling. Acculturation is more complex than being associated with cultural distance and worthy of further exploration.

Genital herpes infection: a review.

Genital herpes infection is life-long and may result in painful and recurrent genital lesions, systemic complications, serious psychosocial morbidity, and rare but serious outcomes in neonates born to infected women, including permanent neurological handicap and death. Herpes simplex virus (HSV)-2 is the principal cause, with an increasing proportion of first-episode disease caused by HSV-1. Genital HSV transmission is usually due to asymptomatic viral shedding by people who are unaware that they are infected and clinical screening fails to detect most infections. Type-specific serological assays can distinguish the two viral subtypes, but these are expensive and currently restricted to a few research settings. Most infections are asymptomatic, or cause a mild illness which does not lead to health service attendance; but the limited evidence suggests a rise in disease incidence, perhaps related to a fall in HSV-1 age-specific prevalences. The prevalences of HSV genital infections increase with age and numbers of sexual partners, with higher rates in specific ethnic and low socioeconomic groups. However, infection is not restricted to high-risk populations. Antiviral agents, such as acyclovir, can reduce disease severity, prevent recurrences and shorten periods of viral shedding, but currently there are no effective population control measures. This may change with the advent of HSV vaccines, if their safety and long-term efficacy are confirmed. Possible applications for vaccines may include the suppression of disease and recurrences in patients with genital infections (immunotherapy), the prevention of viral transmission to their seronegative partners, and immunoprevention through vaccinating the latter. Economic evaluations of existing and potential control strategies, age-specific population HSV-1 and 2 seroprevalence studies for targeting future interventions, and cohort studies to elucidate the natural history of HSV-2 infections are needed.

An investigation of the role of fathers in immunization uptake.

BACKGROUND: Mothers, but not fathers, are the usual focus of strategies to maximize immunization coverage in low income countries. METHODS: A study of the immunization determinants of children aged 12-18 months was conducted in 1991 in the Eastern Region of Ghana using structured interviews of a population sample of 294 mothers and 170 (67%) of the children's fathers. RESULTS: Fathers were more likely than mothers to perceive that the fathers had participated in the decision to send children for immunizations. Where both parents reported that the father had participated in the decision, and he could speak English, the child was more likely to have completed the immunization schedule by 12 months (OR = 5.7, 95% confidence interval [CI]: 1.5-21.7), independently of other factors. Neither the father's participation, nor his ability to speak English, was independently associated with the child's immunization status. CONCLUSIONS: The results of the study suggest that, where fathers have a higher level of education, programmes which are designed to involve them in decisions about their children's use of preventive health services have the potential to increase timely immunization coverage levels.

PIP: Programs and strategies to maximize immunization coverage in low income countries generally focus upon mothers. 294 mothers of children aged 12-18 months and 170 (67%) of the children's fathers were interviewed in a 1991 study of immunization determinants in the Eastern Region of Ghana. Fathers were more likely than mothers to perceive that the fathers had participated in the decision to send children for immunizations. Where both parents reported the father's involvement in the decision making process, and the father could speak English, the child was more likely to have completed the immunization schedule by 12 months, independently of other factors. Neither the father's participation, nor his ability to speak English, was independently associated with the child's immunization status. These findings suggest that where fathers have a relatively higher level of education, programs involving them in decision making about their children's use of preventive health services may increase timely immunization coverage levels.

Shifting the paradigm in tuberculosis control: illustrations from India.

Drawing on literature from India and key contributions from social science, this paper asks and attempts to answer the question 'who is to blame for treatment failures in TB'? Some key lessons emerge: effective tuberculosis control cannot be achieved so long as the disease is considered in isolation from the social processes that maintain it, create the conditions facilitating its spread and act as barriers to care. Insights into the economic and social burdens incurred with a diagnosis of TB are essential to understand why many patients, especially the most disadvantaged, are unable to comply with treatment regimens. TB and health care interventions need to be appropriate to the health service contexts in which they are applied, and sensitive to the competing demands, needs and priorities of people's lives. The paper argues for the need to reorient TB control programmes towards enabling patients to obtain care. The problem of access emerges as central to people's ability to obtain and maintain appropriate therapy. Examples and characteristics of successful non-governmental projects, from which policy makers, programmers and practitioners could learn, are outlined and contrasted with more rigid directly observed treatment approaches. We conclude that treatment failures are not patient failures, and that TB control programmes need to address the social dimensions of TB, and adhere to the principles of good TB care, with the same commitment that is devoted to ensuring patients follow treatment guidelines. We suggest a paradigm shift away from a focus on diseased patients towards enabling health in the community.

Missed opportunities for immunizations at curative and preventive health care visits.

PIP: In Ghana, a population-based immunization coverage survey revealed missed opportunities at preventive and curative care visits among children 12-18 months old attending the local hospital in the eastern region of Ghana. Parent-held immunization cards do not have a place to record curative care visits. If pediatric patient's immunization schedules were not complete, health workers tracked down outpatient department (OPD) tickets and recorded the dates of previous visits to the OPD. 60.5% of 294 children were completely immunized. 21.4% had missed an opportunity during at least 1 visit to a clinic compared to 32% in a review of 10 studies from developing countries. Had health workers taken the opportunity to immunize children without a complete immunization schedule, the immunization coverage level would have been 66.7%. 56.9% of the 116 incompletely immunized children had received curative care at the local hospital. The researchers could obtain OPD numbers on only 39 of 66 children. They recovered hospital records for 32 children. The dates for all OPD visits were recorded on these records. The mothers of the remaining 27 tended to lose the flimsy OPD ticket. 30 of the 32 children had missed an opportunity for immunization, particularly for measles (24). 20 children needed only 1 more visit to complete the schedule. Had these opportunities not been missed at OPDs, immunization coverage could have increased to 70.7%. If all children who received curative care at the hospital had completed the schedule, immunization coverage would have increased even further to 83%. 75% of missed opportunities were for measles vaccination. Logistical problems at the hospital, shortage of community health nurses, and assumption of false contraindications by some hospital workers were responsible for missed opportunities. OPD nurses often referred children with incomplete immunization to the primary health care department, 20 m away. In conclusion, a comprehensive, integrated, home-based health record with all records of non-inpatient preventive and curative health events, including dates of immunization, is needed.^ieng

Young adults' preferred options for receiving chlamydia screening test results: a cross-sectional survey of 6085 young adults.

We investigated how young adults aged 18-29 years would like to be notified of chlamydia screening test results, and, when they test positive, their willingness and preferred mechanism for informing their partners. We conducted a cross-sectional survey of 6085 young adults and found that a call to their mobile phone was their preferred way of receiving positive test results (selected by 50%), followed by email. Text messages (short message service [SMS]) and calls to landline phones were unpopular options, selected by between 5 and 10%. Over 75% of respondents stated they would inform their current partner of a positive chlamydia diagnosis, and 50% would inform their previous partners. Most were willing to receive yearly reminders to go for a chlamydia test. Young adults preference for being informed of chlamydia test results by mobile phone call, rather than by email or SMS text, especially if they test positive, suggests they place high value on the security of the communication mechanism. Offering a range of mechanisms for receipt of test results may increase the acceptability and coverage of sexually transmitted infection (STI) control strategies.

Rectal adenocarcinoma following cranio-spinal radiotherapy for cerebellar medulloblastoma.

The authors present a case of a 16-year-old female diagnosed with rectal adenocarcinoma 10 years after receiving cranio-spinal radiotherapy for a cerebellar medulloblastoma. While the risk of a second malignancy is recognised to be increased in children previously treated with radiotherapy, rectal adenocarcinoma is a rare presentation. A child presenting with symptoms of weight loss and a change in bowel habit in a patient who has previously received radiotherapy should alert practitioners to the possibility of a colorectal malignancy.

Sexually transmitted infections -- factors associated with quality of care among private general practitioners.

OBJECTIVES: To study the factors associated with quality of sexually transmitted infection (STI) care among private general practitioners in Gauteng. METHODS: We analysed 1 194 records of patients attending 26 randomly selected GP practices in the first 3 months of 2000 and 2002, for 3 STI syndromes, namely urethral discharge, pelvic inflammatory disease and genital ulcers. We assessed adherence to nationally accepted STI treatment guidelines and analysed the influence of patient and practice-level variables on effectiveness of STI drug regimens and trends over time. RESULTS: After controlling for syndrome mix, district and time period, appropriate drug treatment for STIs was significantly associated with the client having medical aid (p < 0.001), recent graduation as a medical practitioner (p < 0.001) and male GP gender (p = 0.007). Between 2000 and 2002, STI care improved for clients with medical aids but for not cash clients. CONCLUSIONS: There was variation in the quality of prescribing for STIs among GPs and positive trends in this prescribing. There is a need for interventions that address the financial incentives that may hamper quality of STI care for cash clients.

Improving the quality of STI care by private general practitioners: a South African case study.

OBJECTIVES: Evaluation of an intervention to improve quality of sexually transmitted infections (STI) care among 64 private general practitioners (GPs) working in two urban districts in Gauteng Province, South Africa. METHODS: We implemented a multifaceted intervention, the core of which were four interactive continuing medical education seminars. Changes in STI treatment practices were evaluated through record reviews before and after the continuing medical education intervention in 17 randomly selected practices in the intervention districts and in nine randomly selected practices from a reference GP group (n = 34). RESULTS: There were statistically significant improvements in the quality of drug treatment for urethral discharge but not pelvic inflammatory disease among both intervention and reference GPs. CONCLUSIONS: Improvements in STI quality were possibly the result of a background secular trend rather than the intervention itself. Further research is needed on financial and other incentives to improved quality of STI care in the private sector environment.

HIV counselling and care programmes at the district level in Ghana.

The district hospital is the focus for the presentation of HIV-related disease in rural sub-Saharan Africa. Patients require not only medical care, but often economic support and counselling for themselves and their families. Psychosocial support should be provided at the hospital and in the home, the latter often being the preferred option. A team approach to HIV disease care and counselling, with careful selection and support of staff, and appropriate training in counselling skills is essential. A primary health care approach at the district level, mobilizing community participation and intersectoral support is necessary. Community Health Outreach Departments, as integral parts of the district hospital, are recommended and could pilot low-cost HIV hospital and home-care programmes.

PIP: The district has a typical population size of 100,000-300,000 people and is the most peripheral unit of local government and administration in many developing countries. It is also the focus for the organization and coordination of community health care and preventive and curative health services. Where HIV infection and related disease are concerned, individuals present at the district hospital in rural sub-Saharan Africa to obtain medical care along with economic support and counselling for themselves and their families. Psychosocial support should be provided at the hospital and especially in the home. The author outlines issues and problems to address in setting up an HIV counseling and care program at the district level. Sections consider HIV support and counseling, hospital and home-care programs, and the HIV counselling team. A team approach to HIV disease care and counseling is extremely important. Staff must be carefully selected and supported with appropriate training in counselling. A primary health care approach is called for with community participation and intersectoral support. Community health outreach departments are recommended as integral parts of the district hospital; they could even pilot low-cost HIV hospital and home care programs.

Improving the quality of private sector delivery of public health services: challenges and strategies.

Despite significant successes in controlling a number of communicable diseases in low and middle income countries, important challenges remain, one being that a large proportion of patients with conditions of public health significance, such as tuberculosis, malaria, or sexually transmitted diseases, seek care in the largely unregulated 'for profit' private sector. Private providers (PPs) often offer services which are perceived by users to be more attractive. However, the available evidence suggests that serious deficiencies in technical quality are often present. Evaluations of interventions to promote evidence-based care in high income countries have shown that multi-faceted strategies which increase provider knowledge have had some success in improving service quality. A wider range of factors needs to be considered in low and middle income countries (LMICs), especially factors which contribute to discrepancies between provider knowledge and practice. Studies have shown that PPs, especially, perceive or experience patient and community pressures to provide inappropriate treatments. LMIC governments also lack the capacity to enforce regulatory controls. Context-specific multi-faceted strategies are needed, including the local adaptation and dissemination to providers of relevant evidence, the education of patients and communities to adopt effective treatment-seeking and treatment-taking behaviour, and feasible mechanisms for ensuring and monitoring service quality, which may include a role for self-regulation by provider organizations or provider accreditation. Developing, implementing and evaluating strategies to improve the quality of service provision will depend on the involvement of the key stakeholders, including policy makers and PPs. Focusing on studies from Asia, Africa and Latin America, this paper develops a model for identifying the influences on PPs, mainly private medical practitioners, in their management of conditions of public health significance. Based on this, multi-faceted strategies for improving the quality of treatment provision are suggested. Interventions need to be inexpensive, practical, efficient, effective and sustainable over the medium to long term. Achieving this is a significant challenge.
