RESUMO
BACKGROUND: The translation of public health research evidence into policy is critical to strengthening the capacity of local health systems to respond to major health challenges. However, a limited amount of public health research evidence generated in developing countries is actually translated into policy because of various factors. This study sought to explore the process of health research knowledge translation into policy and to identify factors that facilitate or hinder the process in Zambia. METHODS: This work was an exploratory qualitative study comprising two phases. Firstly, a document review of health policies and strategic frameworks governing research was undertaken to understand the macro-environment for knowledge translation in Zambia. Secondly, key informant interviews were conducted with those responsible for health research and policy formulation. The study interviewed 15 key informants and a thematic analysis approach was used. RESULTS: The document review showed that there are policy efforts to promote knowledge translation through improvement of the research macro-environment. However, the interviews showed that coordination and linkage of the knowledge creation, translation and policy-making processes remains a challenge owing to lack of research knowledge translation capacity, limited resources and lack of knowledge hubs. Emerging local research leadership and the availability of existing stock of underutilized local health research data provide an opportunity to enhance knowledge translation to feed into policy processes in Zambia. CONCLUSIONS: Public health research knowledge translation into policy remains a challenge in Zambia. To enhance the uptake of research evidence in policy-making, this study suggests the need for improved coordination, financing and capacity-building in knowledge translation processes for both health researchers and policy-makers.

BACKGROUND: Adverse childhood experiences (ACEs) have been linked to long-term health outcomes, while the impact of such experience has not been investigated among Zambian youth. This study examined the associations of ACEs with individual and clusters of health risk behavior among college students in Zambia. METHOD: A total of 624 college students participated in this cross-sectional study. A self-administered questionnaire was used to collect information on their ACEs and health risk behaviors. RESULTS: There were 58.3% (364) reporting some forms of ACEs, with 27.6% (172), 16.3% (102), and 14.4% (90) being exposed to 1, 2, and ≥ 3 ACEs, respectively. The prevalence of health risk behaviors ranged from 6.0 to 34.2%. Overall, ACEs were associated with increased risk of smoking, binge drinking, suicide attempt, risky sexual behaviors, and illicit drug use. Logistic regression suggested that participants with ≥ 3 ACEs (OR, 3.62; 95% CI, 2.14-6.13) were more likely to engage in the unhealthy cluster, characterized by the presence of any health risk behavior, than those without ACE. CONCLUSION: ACEs were associated with individual and clustering of health risk behaviors among Zambia college students. Our study suggests that early intervention is needed to prevent long-term adverse health consequences in this population.

PURPOSE OF REVIEW: To systematically review recent findings on the role of immune cell activation in the pathogenesis of hypertension in people living with HIV (PLWH) and compare studies from Sub-Saharan Africa with what is reported in the USA and European literature according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RECENT FINDINGS: PLWH have an increased risk for development of hypertension and cardiovascular disease. Chronic immune activation contributes to hypertension but the inflammatory milieu that predisposes PLWH to hypertension is poorly understood. We identified 45 relevant studies from 13 unique African countries. The prevalence of hypertension in PLWH on antiretroviral therapy (ART) and the ART-naive PLWH ranged from 6 to 50% and 2 to 41%, respectively. Interleukin (IL)-17A, interferon (IFN)-γ, and higher CD4+ T cell counts were associated with hypertension in ART-treated participants. Targeting adaptive immune activation could provide improved care for hypertensive PLWH. Further research is needed to characterize the inflammatory milieu contributing to hypertension in PLWH especially in African populations where the global burden of HIV is the highest.

Risky sexual behaviors are important factors driving the HIV/AIDS epidemic. Although Zambia experiences a high HIV prevalence, especially among youth, there is a dearth of information regarding risky sexual behaviors among young adults. Therefore, we investigated the prevalence and associated factors of risky sexual behaviors among college students in Lusaka, Zambia. A cross-sectional study was conducted in February 2017 among 427 college students at the University of Zambia. Participants reported their sexual behaviors, sexual attitudes, and lifestyle using self-administered questionnaires. Multinomial logistic regression models were employed to assess potential determinants of risky sexual behaviors. Among the 205 students who reported ever having sex, 148 (72.2%) engaged in risky sexual behaviors in the last 12 months. Participants who were older (OR 1.30, 95% CI 1.12-1.51), engaged in low physical activity (OR 2.25, 95% CI 1.05-4.84), and reported liberal sexual attitudes (OR 1.88, 95% CI 1.02-3.47) were more likely to engage in any risky sexual behavior, while frequent alcohol use (OR 8.38, 95% CI 4.60-15.27) and suicide attempts (OR 6.42, 95% CI 2.03-20.29) predicted multiple risky sexual behaviors. In conclusion, this study indicates that Zambian college students' risky sexual behaviors are associated with multiple behavioral health risks. Future research should consider using a multiple-behavior change intervention.

BACKGROUND: The focus of the community anti-retroviral therapy Group model is on drug refill, adherence and support groups. However, laboratory services are completely neglected in this model, and stable patient still have to go to the clinic for blood draws after drugs refills from the community. Due to the introduction of new ART drugs, the guidelines now recommend the use of viral loads to guide decision in switching all patients from NNRTI to dolutegravir based first line ART regimens. But the national viral load testing coverage stands at 37% and and falls short of meeting the global UNAIDS and phlebotomy delivery system is congested. The purpose of this study was to identify the perceptions in decentralizing phlebotomy services into the community anti-retroviral therapy Group model. METHOD: A qualitative case study design was used. Data were collected through ten Focused group discussions among community anti-retroviral therapy Group members, community and health care workers at anti-retroviral therapy clinics and in-depth interviews with five key informants. Data were managed with the help of Nvivo version 10 and analyzed using thematic method. RESULTS: Positive perceptions were identified as those which contributed to decongesting phlebotomy rooms, reduced missing phlebotomy appointments, work Load, and lost results. Improved quality of phlebotomy service delivery and testing coverage, innovative access to laboratory services and encouraged patient's accountability. The negative perceptions were compromised sample integrity, inability to perform prevention control and patients less contact with clinicians. CONCLUSION: The study has demonstrated that decentralizing phlebotomy services within the CAG model has greater potential to improve the quality of services delivery for patients. In addition, it has perceived threats on the quality of specimen collected, patient's safety, and health care.

BACKGROUND: While health care needs assessments have been conducted among juveniles or adolescents by researchers in developed countries, assessments using an ethics framework particularly in developing countries are lacking. We analysed the health care needs among adolescents at the Nakambala Correctional Institution in Zambia, using the Beauchamp and Childress ethics framework. The ethics approach facilitated analysis of moral injustices or dilemmas triggered by health care needs at the individual (adolescent) level. METHODS: The research team utilized 35 in-depth interviews with juveniles, 6 key informant interviews and 2 focus group discussions to collect data. We analysed the data using thematic analysis. The use of three sources of data facilitated triangulation of data. RESULTS: Common health problems included HIV/AIDS, STIs, flu, diarrhoea, rashes, and malaria. Although there are some health promotion strategies at the Nakambala Approved School, the respondents classified the health care system as inadequate. The unfavourable social context which included clouded rooms and lack of adolescent health friendly services unfairly exposed adolescents to several health risks and behaviours thus undermining the ethics principle of social justice. In addition, the limited prioritisation of adolescent centres by the stakeholders and erratic funding also worsened injustices by weakening the health care system. Whereas the inadequate medical and drug supplies, shortage of health workers in the nearby health facilities and weak referral systems excluded the juveniles from enjoying maximum health benefits thus undermining adolescents' wellbeing or beneficence. Inadequate medical and drug supplies as well as non-availability of adolescent friendly health services at the nearest health facility did not only affect social justice and beneficence ethics principles but also threatened juveniles' privacy, liberty and confidentiality as well as autonomy with regard to health service utilisation. CONCLUSION: Adequately addressing the health needs in correctional institutions may require adopting an ethics framework in conducting health needs assessment. An ethics approach is important because it facilitates understanding of moral dilemmas that arise due to health needs. Furthermore, strategies for addressing health needs related to one ethics principle may have a positive ripple effect over other health needs as the principles are intertwined thus facilitating a comprehensive response to health needs.

BACKGROUND: In 2010 the government of the republic of Zambia stopped training traditional birth attendants and forbade them from conducting home deliveries as they were viewed as contributing to maternal mortality. This study explored positive and negative maternal health related experiences and effects of the ban in a rural district of Kazungula. METHODS: This was a phenomenological study and data were collected through focus group discussions as well as in-depth interviews with trained traditional birth attendants (tTBAs) and key informant interviews with six female traditional leaders that were selected one from each of the six zones. All 22 trained tTBAs from three clinic catchment areas were included in the study. Content analysis was used to analyse the data after coding it using NVIVO 8 software. RESULTS: Home deliveries have continued despite the community and tTBAs being aware of the ban. The ban has had both negative and positive effects on the community. Positive effects include early detection and management of pregnancy complications, enhanced HIV/AIDS prevention and better management of post-natal conditions, reduced criticisms of tTBAs from the community in case of birth complications, and quick response at health facilities in case of an emergency. Negatives effects of the ban include increased work load on the part of health workers, high cost for lodging at health facilities and traveling to health facilities, as well as tTBAs feeling neglected, loss of respect and recognition by the community. CONCLUSION: Countries should design their approach to banning tTBAs differently depending on contextual factors. Further, it is important to consider adopting a step wise approach when implementing the ban as the process of banning tTBAs may trigger several negative effects.

BACKGROUND: The emergence of Acquired Immunodeficiency Syndrome has highlighted the increased incidence and importance of the disease caused by Non-tuberculous Mycobacteria (NTM). While disease due to M. avium-intracellulare complex is apparently common throughout the world, other Non-tuberculous mycobacterial species have been isolated from both immunocompromised and immunocompetent individuals. The increasing number of infections caused by these organisms has made it clinically important to quickly identify mycobacterial species. The diagnosis of a pathogenic versus a non-pathogenic species not only has epidemiological implications but is also relevant to the demands of patient management. Since antibiotic treatment varies according to the species encountered, species identification would reduce the burden of some of these emerging opportunistic pathogens especially in immunocompromised patients and improve their quality of life. FINDINGS: A total of 91 NTM suspected isolates from four regions of Zambia were included in the study. These isolates were identified using the sequence analysis of the 16S-23S rRNA intergenic transcribed spacer (ITS) region of Mycobacteria. Fifty-four of the 91 (59%) isolates were identified as NTM and these included M. intracellulare (27.8%), M. lentiflavum (16.7%), M. avium (14.8%), M. fortuitum (7.4%), M. gordonae (7.4%), M. kumamotonense (3.7%), M. indicus pranii (3.7%), M. peregrinum (3.7%), M. elephantis (1.85%), M. flavescens (1.85%), M. asiaticum (1.85%), M. bouchedurhonense (1.85%), M. chimaera (1.85%), M. europaeum (1.85%), M. neourum (1.85%), M. nonchromogenicum (1.5%). CONCLUSION: The study has shown that DNA sequencing of the ITS region may be useful in the preliminary identification of NTM species. All species identified in this study were potentially pathogenic.

BACKGROUND: Research outputs in sub-Saharan Africa may be limited by a scarcity of clinical research expertise. In Zambia, clinical and biomedical postgraduate students are often delayed in graduation due to challenges in completing their research dissertations. We sought to strengthen institutional research capacity by supporting student and faculty researchers through weekly epidemiology and biostatistics clinics. METHODS: We instituted a weekly Analytical Support Clinic at the University of Zambia, School of Medicine. A combination of biostatisticians, clinical researchers and epidemiologists meet weekly with clients to address questions of proposal development, data management and analysis. Clinic sign-in sheets were reviewed. RESULTS: 109 students and faculty members accounted for 197 visits to the Clinic. Nearly all clients (107/109, 98.2%) were undergraduate or postgraduate students. Reasons for attending the Clinic were primarily for proposal development (46.7%) and data management/analysis (42.1%). The most common specific reasons for seeking help were data analysis and interpretation (36.5%), development of study design and research questions (26.9%) and sample size calculation (21.8%). CONCLUSIONS: The Analytical Support Clinic is an important vehicle for strengthening postgraduate research through one-on-one and small group demand-driven interactions. The clinic approach supplements mentorship from departmental supervisors, providing specific expertise and contextual teaching.
RESUMO
BACKGROUND: In response to Zambia's critical human resources for health challenges, a number of strategies have been implemented to recruit and retain health workers in rural and remote areas. Prior to this study, the effectiveness of these strategies had not been investigated. The purpose of this study was to determine the impacts of the various health worker retention strategies on health workers in two rural districts of Zambia. METHODS: Using a modified outcome mapping approach, cross-sectional qualitative and quantitative data were collected from health workers and other stakeholders through focus group discussions and individual interview questionnaires and were supplemented by administrative data. Key themes emerging from qualitative data were identified from transcripts using thematic analysis. Quantitative data were analyzed descriptively as well as by regression modelling. In the latter, the degree to which variation in health workers' self-reported job satisfaction, likelihood of leaving, and frequency of considering leaving, were modelled as functions of participation in each of several retention strategies while controlling for age, gender, profession, and district. RESULTS: Nineteen health worker recruitment and retention strategies were identified and 45 health care workers interviewed in the two districts; participation in each strategy varied from 0% to 80% of study participants. Although a salary top-up for health workers in rural areas was identified as the most effective incentive, almost none of the recruitment and retention strategies were significant predictors of health workers' job satisfaction, likelihood of leaving, or frequency of considering leaving, which were in large part explained by individual characteristics such as age, gender, and profession. These quantitative findings were consistent with the qualitative data, which indicated that existing strategies fail to address major problems identified by health workers in these districts, such as poor living and working conditions. CONCLUSIONS: Although somewhat limited by a small sample size and the cross-sectional nature of the primary data available, the results nonetheless show that the many health worker recruitment and retention strategies implemented in rural Zambia appear to have little or no impact on keeping health workers in rural areas, and highlight key issues for future recruitment and retention efforts.

BACKGROUND: Most African countries are facing a human resources for health (HRH) crisis, lacking the required workforce to deliver basic health care, including care for mothers and children. This is especially acute in rural areas and has limited countries' abilities to meet maternal, newborn, and child health (MNCH) targets outlined by Millennium Development Goals 4 and 5. To address the HRH challenges, evidence-based deployment and training policies are required. However, the resources available to country-level policy makers to create such policies are limited. To inform future HRH planning, a scoping review was conducted to identify the type, extent, and quality of evidence that exists on HRH policies for rural MNCH in Africa. METHODS: Fourteen electronic health and health education databases were searched for peer-reviewed papers specific to training and deployment policies for doctors, nurses, and midwives for rural MNCH in African countries with English, Portuguese, or French as official languages. Non-peer reviewed literature and policy documents were also identified through systematic searches of selected international organizations and government websites. Documents were included based on pre-determined criteria. RESULTS: There was an overall paucity of information on training and deployment policies for HRH for MNCH in rural Africa; 37 articles met the inclusion criteria. Of these, the majority of primary research studies employed a variety of qualitative and quantitative methods. Doctors, nurses, and midwives were equally represented in the selected policy literature. Policies focusing exclusively on training or deployment were limited; most documents focused on both training and deployment or were broader with embedded implications for the management of HRH or MNCH. Relevant government websites varied in functionality and in the availability of policy documents. CONCLUSIONS: The lack of available documentation and an apparent bias towards HRH research in developed areas suggest a need for strengthened capacity for HRH policy research in Africa. This will result in enhanced potential for evidence uptake into policy. Enhanced alignment between policy-makers' information needs and the independent research agenda could further assist knowledge development and uptake. The results of this scoping review informed an in-depth analysis of relevant policies in a sub-set of African countries.

BACKGROUND: Human resources for health (HRH) planning in Zambia, as in other countries, is often done by comparing current HRH numbers with established posts, without considering whether population health needs are being met. Service-based HRH planning compares the number and type of services required by populations, given their needs, with the capacity of existing HRH to perform those services. The objective of the study was to demonstrate the effectiveness of service-based HRH planning through its adaptation in two rural Zambian districts, Gwembe and Chibombo. METHODS: The health conditions causing the greatest mortality and morbidity in each district were identified using administrative data and consultations with community health committees and health workers. The number and type of health care services required to address these conditions were estimated based on their population sizes, incidence and prevalence of each condition, and desired levels of service. The capacity of each district's health workers to provide these services was estimated using a survey of health workers (n=44) that assessed the availability of their specific competencies. RESULTS: The primary health conditions identified in the two districts were HIV/AIDS in Gwembe and malaria in Chibombo. Although the competencies of the existing health workforces in these two mostly aligned with these conditions, some substantial gaps were found between the services the workforce can provide and the services their populations need. The largest gaps identified in both districts were: performing laboratory testing and interpreting results, performing diagnostic imaging and interpreting results, taking and interpreting a patient's medical history, performing a physical examination, identifying and diagnosing the illness in question, and assessing eligibility for antiretroviral treatment. CONCLUSIONS: Although active, productive, and competent, health workers in these districts are too few to meet the leading health care needs of their populations. Given the specific competencies most lacking, on-site training of existing health workers to develop these competencies may be the best approach to addressing the identified gaps. Continued use of the service-based approach in Zambia will enhance the country's ability to align the training, management, and deployment of its health workforce to meet the needs of its people.

BACKGROUND: The World Health Organization has promoted a shift towards the test-and-treat-all strategy to accelerate the elimination of HIV/AIDS. Zambia was one of the early African countries to adopt this strategy as the policy change was officially announced on national television by the republican president on 15th August 2017. This study explored the communication and implementation challenges of the HIV/AIDS policy change to test-and-treat-all in selected public health facilities in Lusaka District, Zambia. METHODS: A qualitative case study design was employed with a purposeful sample of policy makers, international partners, National AIDS Council representatives, health facility managers, and frontline health providers in selected tertiary, secondary and primary health facilities in the Lusaka District, Zambia. Thematic data analysis was performed using NVivo 12 Pro software. RESULTS: In total, 22 key informant interviews and 3 focus group discussions were conducted. The government relied on formal and informal channels to communicate the test-and-treat-all policy change to health providers. Whilst HIV policy changes were reflected in the National HIV/AIDS Strategic Framework, there was little awareness of this policy by the frontline providers. The use of informal communication channels such as verbal and text instructions affected health providers' implementation of the test-and-treat-all. Electronic and print media were ineffective in communicating the test-and-treat-all policy change to some sections of the public. Top-down stakeholder engagement, limited health worker training, and poor financing negatively affected the implementation of the test-and-treat-all policy change. Acceptability of the test-and-treat-all policy change was shaped by positive provider perceptions of its benefits, limited sense of policy ownership, and resistance by the non-treatment-ready patients. Furthermore, unintended consequences of the test-and-treat-all policy change on human resources for health and facility infrastructure were reported. CONCLUSION: Effective test-and-treat-all policy change communication is vital for successful policy implementation as it enhances interpretation and adoption among health providers and patients. There is a need to enhance collaboration among policy makers, implementers and the public to develop and apply communication strategies that facilitate the adoption of the test-and-treat-all policy changes to sustain gains in the fight against HIV/AIDS.
RESUMO
Strong cultures of mentorship and research remain underdeveloped at many African universities, threatening future knowledge generation essential for health and development on the continent. To address these challenges, a mentorship program was developed in 2018 at the University of Zambia with an aim to enhance the institutional culture of mentorship and to build institutional capacity through an innovative 'train the trainer' faculty development model. In this study, we documented perceptions of lived experiences related to mentorship culture by following trainers and trainees and their mentees over two years. We analyzed these perceptions to assess changes in institutional attributes regarding mentorship. We identified positive change in institutional culture towards mentorship, and this change appeared sustainable over time. However, a slight decrease in indicators for year two emphasizes the need for a continued culture of learning rather than assuming that one-off training will be sufficient to change culture.

The University of Zambia (UNZA) Mentor Training Program is conducted annually to strengthen the mentorship capacity of postgraduate programs for the health professions. This intensive five-session course trains faculty members in the mentorship of students. Established by senior UNZA leaders and US-based collaborators, this program was designed to address gaps in mentorship identified at the institutional level. Faculty facilitators developed the course curriculum and used a train-the-trainer model to ensure program sustainability. Participants were faculty members who mentor PhD and Master of Medicine students. To assess the program's impact, mentors and their mentees completed questionnaires on the mentor's mentoring competencies at the end of the course and 1 year later. Competency scores were compared longitudinally to quantify potential changes in mentoring behaviors. Mentors and mentees alike noted mentor growth in all competency domains from postcourse to 1 year later, providing evidence of a trend toward improvement in mentorship and that the program may have sustainable and positive effects on mentoring behaviors over time. Salient areas of growth corresponded to emphasized topics and discussions, including addressing diversity, aligning expectations, assessing capacities, motivating mentees, and fostering independence. These findings suggest that mentors internalized this content and transferred it to behavior change. The behavior changes may reveal a larger change in the institutional environment around the mentoring of students. The UNZA Mentor Training Program appears to have sustained impact after a year and should bode well for future benefits to students, faculty, and the institution.

Background and Objectives: Early and Enhanced Clinical Exposure immediately places postgraduate students in a clinical setting and incorporates continual hands-on instruction throughout their studies. It aims to motivate students by strengthening their academics, improving clinical and communication skills, and increasing their confidence. The underlying principles are to provide a clinical context and to ensure that the patient remains the centre of learning. The School of Nursing Sciences implemented this model in 2021 to produce hands-on Masters-level neonatal practitioners who can work in multidisciplinary clinical contexts. Therefore, this study explored the experiences of postgraduate nursing students on the Early and Enhanced Clinical Exposure model and draw implications for the future. Methods: A phenomenological study design was utilized at the University of Zambia, School of Nursing Sciences and comprised of eight Master of Science Neonatal Nursing students in their second year. Convenience sampling was used to select the study site and participants. Data was collected between 15th January 2023 and 31st January 2023 using an in-depth interview guide. Audio recording and notes were transcribed immediately after data collection. Data analysis was conducted using thematic analysis and codes and themes were constructed from the coded data. Ethical clearance and permission were sought before conducting the study. Results: Four major themes emerged from the study: identity and role confusion, challenging and hectic experiences, positive educational experiences, and personal and professional growth. These themes contributed to the promotion of evidence-based practice by helping students to assess, diagnose, and treat various conditions, as well as gain interest, experience, knowledge, and exposure. Conclusion: The model has a significant impact on motivation to learn, as evidenced by reported increased skill level with potential for use in clinical practice. It is recommended that it be implemented in all postgraduate programs for full-time students.
RESUMO
Background: Hypertension is common in people living with HIV (PLWH) on antiretroviral therapy (ART). In the general population and in experimental animal models, the incidence of hypertension is greater in males than in females, especially during the premenopausal period. However, it is not known whether there are sex differences in hypertension associated with HIV and ART, and the factors contributing to incident hypertension among PLWH have not been well characterized. In this study, we aimed to determine the time course, sex differences and factors associated with incident hypertension in PLWH initiating ART. Methods and results: We conducted a retrospective study in which we used programmatic data from the ART registry to identify sex differences in the determinants of incident hypertension among PLWH initiating the ART regimen from Livingstone University Teaching Hospital in Zambia and followed for 8 years. Males developed hypertension earlier, 2 years after initiating ART, compared to 6 years in females. In multivariable analysis, increasing age, baseline systolic blood pressure and baseline mean arterial pressure (MAP) were associated with increased risk for developing incident hypertension. Also, participants who switched to the integrase strand transfer inhibitor, dolutegravir (DTG) or the protease inhibitor, lopinavir boosted with ritonavir were 2 and 3 times more likely to develop hypertension when compared to those on non-nucleoside reverse transcriptase inhibitors (NNRTIs). However, these relationships were abrogated by sex, as self-reported male sex was the major contributor in predicting incident hypertension. While none of the factors remained significantly associated with incident hypertension upon multivariate analysis among females, body mass index (BMI), and use of protease inhibitors remained strongly associated with hypertension among males. Conclusion: Our results indicate that the use of protease inhibitors and BMI are important predictors of incident hypertension among males. Thus, blood pressure and BMI should be closely monitored, particularly in males living with HIV on protease inhibitors. In addition, identifying specific factors that protect females from developing hypertension early is important but remains to be determined.
RESUMO
BACKGROUND: High blood pressure (BP) is associated with high-salt consumption especially in sub-Saharan Africa. Although the pressor effect of salt is viewed as a chronic effect, some studies suggest that a salty meal may increase BP immediately in some individuals, and that this effect may cause endothelial dysfunction. Therefore, the aim of our research was to study the immediate pressor response to oral salt (IPROS) and its determinants, with the expectation that a simple methodology may be devised to diagnose it in the clinic or in low-resource environments. METHODS: We conducted a time series trial at Livingstone Central Hospital. We present data in 127 normotensive participants who ingested 2 g of sodium chloride; their BP was monitored for 120 minutes in intervals of 10 minutes. Sociodemographic and clinical data were collected. Descriptive and inferential statistics were used for analyses of data. RESULTS: Median age was 30 years (interquartile range, 22-46 years) and 52% were female patients. An increase of ≥10 mmHg in mean arterial pressure (MAP), considered a clinically significant IPROS, was present in 62% of participants. Systolic BP 30 minutes after the salt load was a significant predictor of IPROS, avoiding the need to calculate MAP in the clinic setting. CONCLUSIONS: We confirm the presence of an IPROS in a high proportion (62%) of otherwise normotensive participants. The average time course for this response was 30 minutes and its duration was sustained for the 120-minutes period of study in most of the participants. Prediction of IPROS by ∆SBP (change in systolic blood pressure) at 30 minutes allows for easy assessment of possible responder status in the clinic. Our data indicate that the IPROS to oral salt-loads in the range currently consumed by the Western world and African populations in single meals may increase the 24-hour BP load, which is a risk factor for hypertension and target organ damage. The relevance of our findings indicates the need to include dietary sodium assessment in the diagnosis, prevention, and management of high BP.
RESUMO
Background: An Advanced Practice Nurse is a generalist or specialized nurse who has acquired thorough graduate education a minimum of a master's degree. The need for Advanced Practice Nurses is increasingly recognized globally. This paper describes the process, which was undertaken by School of Nursing Sciences, University of Zambia in reviewing and developing advanced practice nursing and midwifery curricula which will be implemented using the Early and Enhanced Clinical Exposure model (EECE). Materials and Methods: The curricula development/review process utilized a modified Taba's Model which followed a step-by-step approach including: 1) desk review, 2) diagnosis of needs (needs assessment), 3) stakeholder consultations, 4) content development, 5) validations and approval from which several lessons were learnt and recommendations made. Findings and recommendations from different stages were used as a basis for reviewing and developing advanced practice nursing and midwifery curricula. Results: Desk review needs assessment and stakeholder consultations identified both strengths and weaknesses in the existing curricula. Major strengths were duration and core courses which met the minimum requirement for postgraduate nursing and midwifery training. Major weaknesses/gaps included some content that was too basic for the master's level and the delayed exposure to practicum sites which limited the development of advanced practice skills. Others were inadequate competence for advanced practice, inadequate research methodology course, lack of content to foster development of personal soft skills and predominant use of traditional teaching methods. Stakeholders recommended implementing advanced, clinical and hands-on Masters of Nursing and Midwifery programmes which resulted in the review of four existing and development of five demand-driven curricula. Conclusion: The reviewed and developed curricula were strengthened to close the identified gaps. Both the reviewed and developed curricula have been implemented using the Early and Enhanced Clinical Exposure Model with a view to producing Advanced Practice Nurses and Midwives who are competent to meet diverse health care needs and contribute to improving patient outcomes.
RESUMO
Introduction: There is a significant shortage of medical subspecialists in Zambia. The government of Zambia, through programmes at the Ministry of Health, spends considerable resources to send patients outside the country for subspecialist medical treatment. The objective of this analysis was to evaluate the current situation pertaining to medical subspecialty training at the University of Zambia School of Medicine (UNZASOM) and to illustrate the new programmes that are to be introduced. Methods: We collected data from formal desk reviews on the state of medical specialisation in Zambia, the UNZASOM graduation archives and patient referral records at the Ministry of Health (MoH). In addition, information on planned subspecialist programmes is presented. Results: From the first graduates in 1986up to 2019,UNZASOM produced 351medical specialists, 63 (18%) in Internal Medicine, 77 (22%) in Obstetrics &Gynaecology, 82 (23%) in Paediatrics&Child Health, 68 (19%) in General Surgery, 17 (5%) in Anaesthesia & Critical Care, 20 (6%) in Orthopaedics &Trauma and 8 (2%) in Urology. The remaining graduates were in Ophthalmology, Psychiatry, Infectious Diseases, Paediatric Surgery and Pathology contributing 1% each. To enhance medical subspecialist training at UNZASOM, new curricula for Breast Surgery, Urology, Glaucoma, Vitreo-retinalSurgery, Adult Gastroenterology, Forensic Pathology, Dermatology & Venereology, Ophthalmology, Gynaecological Oncology and Paediatric anaesthesia, Infectious Diseases, and Gastroenterology were developed. Since 2013, only 44% of patients requiring subspecialist treatment out of Zambia got assisted with the remainder still on the waiting list or having had bad outcomes. Conclusions: These programmes will provide an opportunity for accessible and affordable medical subspecialization training for Zambia and its neighbouring countries. With enhanced infrastructural support, the subspecialists will contribute toward enhanced healthcare provision and improvement in patient outcomes. They will also form a cohort of trainers to expand the space for quality training and skills building of specialists and subspecialists in the region and beyond.
