RESUMO

BACKGROUND: A rapid and affordable point-of-care test is a priority for Neisseria gonorrhoeae control. WHO and Foundation for Innovative New Diagnostics (FIND) have a target product profile for a non-molecular N gonorrhoeae rapid point-of-care test that requires a clinical sensitivity of greater than 80% and a specificity over 95% to be considered useful in syndromic management; test turnaround time should be 30 min or under, and the test should cost less than US$3. A novel lateral flow assay (LFA) was developed to achieve that profile. METHODS: In this cross-sectional study we evaluated the performance of the novel N gonorrhoeae lateral flow assay (NG-LFA) at the primary health-care level in South Africa. Male patients with urethral discharge syndrome and female patients with vaginal discharge syndrome were recruited from five primary health-care facilities in the Buffalo City Metropolitan Municipality health district of South Africa. First-void urine specimens and nurse-collected vaginal swabs were tested in-facility with the NG-LFA and Xpert CT/NG PCR assay. N gonorrhoeae multi-antigen sequence typing (NG-MAST) was performed on all LFA positive specimens. FINDINGS: Between March 7, and Sept 19, 2022, we enrolled 200 male patients with urethral discharge and 200 female patients with vaginal discharge. The median age of male patients was 24 years (IQR 21-31 years), and the median age of female patients was 25 years (IQR 21-32 years). In addition, 23 male patients and 12 female patients who presented at the facility with a partner notification slip were enrolled of whom one (4%) and five (42%) were symptomatic, respectively. NG-LFA and Xpert results were available for all participants. In urine specimens, NG-LFA sensitivity was 96·1% (Wilson 95% CI 91·2-98·3; 123 LFA-positive among 128 PCR-positive specimens) and 91·7% in vaginal swab specimens (78·2-97·1; 33 LFA-positive among 36 PCR-positive). The specificity was 97·2% in urine specimens (90·4-99·2; 70 LFA-negative among 72 PCR-negative) and 96·3% in vaginal specimens (92·2-98·3; 158 LFA-negative among 164 PCR-negative). In 156 LFA-positive specimens, NG-MAST showed 93 different sequence types. INTERPRETATION: The novel NG-LFA had excellent clinical sensitivity and specificity in symptomatic male and female patients. The test met the optimal requirement for sensitivity and the minimal requirement for specificity specified in the target product profile. NG-LFA could provide an important tool to optimise clinical management and reduce excess antibiotic use in settings without direct access to laboratory testing. FUNDING: Global Antimicrobial Resistance Innovation Fund (GAMRIF) via FIND and National Institutes of Health.

RESUMO

In Southern and Eastern Africa, initiation of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been high among adolescent girls and young women (AGYW) offered PrEP. However, persistence and prevention-effective use of PrEP among this critical group continues to be a challenge. We conducted a qualitative sub-study of AGYW from the Community PrEP Study in Eastern Cape Province, South Africa who had high rates of pick up for monthly PrEP refills over two years, but differing levels of PrEP adherence based on tenofovir-diphosphate (TFV-DP) measurements in dried blood spots (DBS). Contrasting 22 AGYW with low versus high levels of TFV-DP in DBS, we qualitatively explored factors which influenced PrEP persistence vs. non-persistence, unique patterns of PrEP use (e.g., discarding or stockpiling), and participant recommendations for improving AGYW prevention-effective use of PrEP in the future. Results showed that PrEP misconceptions and mistrust among participants' social networks negatively influenced adherence. In comparison, supportive families and/or partners and personal trust that PrEP works positively influenced adherence. Those with low adherence described being motivated to come to the site for other study benefits (e.g., reimbursement money, snacks, sanitary pads) and discarding PrEP to avoid stigma associated with being seen with pills. Future PrEP implementation strategies should focus on involving families and partners in PrEP support for AGYW and minimizing PrEP stigma at a community level.Trial registration NCT03977181.

RESUMO

BACKGROUND: South Africa maintains an integrated health system where syndromic management of sexually transmitted infections (STI) is the standard of care. An estimated 2 million cases of Neisseria gonorrhoeae (N. gonorrhoeae) occur in South Africa every year. Point-of-care diagnostic tests (POCT) may address existing STI control limitations such as overtreatment and missed cases. Subsequently, a rapid lateral flow assay with fluorescence-based detection (NG-LFA) with a prototype reader was developed for N. gonorrhoeae detection showing excellent performance and high usability; however, a better understanding is needed for device implementation and integration into clinics. METHODS: A qualitative, time-series assessment using 66 in-depth interviews was conducted among 25 trained healthcare workers involved in the implementation of the NG-LFA. Findings were informed by the Normalization Process Theory (NPT) as per relevant contextual (strategic intentions, adaptive execution, and negotiation capacity) and procedural constructs (coherence, cognitive participation, collective action, reflexive monitoring) to examine device implementation within primary healthcare levels. Interviews were audio-recorded, transcribed, and then analyzed using a thematic approach guided by NPT to interpret results. RESULTS: Overall, healthcare workers agreed that STI POCT could guide better STI clinical decision-making, with consideration for clinic integration such as space constraints, patient flow, and workload. Perceived NG-LFA benefits included enhanced patient receptivity and STI knowledge. Further, healthcare workers reflected on the suitability of the NG-LFA given current limitations with integrated primary care. Recommendations included sufficient STI education, and appropriate departments for first points of entry for STI screening. CONCLUSIONS: The collective action and participation by healthcare workers in the implementation of the NG-LFA revealed adaptive execution within the current facility environment including team compositions, facility-staff receptivity, and STI management experiences. User experiences support future clinic service integration, highlighting the importance of further assessing patient-provider communication for STI care, organizational readiness, and identification of relevant departments for STI screening.

RESUMO

BACKGROUND: Compared to women, South African men are less likely to know their HIV status (78% vs. 89%), have suppressed viral loads (82% vs. 90%), or access HIV prevention services. To achieve epidemic control where heterosexual sexual behavior drives transmission, interventions to improve the uptake of HIV testing services (HTS) and prevention services must also target cis-gendered, heterosexual men. There is limited understanding of these men's needs and wants with regards to accessing pre-exposure prophylaxis (PrEP). METHODS: Adult men (≥ 18 years) from a peri-urban community in Buffalo City Municipality were offered community-based HTS. Those who received a negative HIV test result were offered community-based, same-day oral PrEP initiation. Men initiating PrEP were invited to participate in a study exploring men's HIV prevention needs and reasons for initiating PrEP. An in-depth interview guide, developed using the Network-Individual-Resources model (NIRM), explored men's perceived HIV acquisition risk, prevention needs, and preferences for PrEP initiation. Interviews were conducted by a trained interviewer in isiXhosa or English, audio-recorded and transcribed. Thematic analysis was used, guided by the NIRM to generate findings. RESULTS: Twenty-two men (age range 18-57 years) initiated PrEP and consented to study participation. Men reported elevated HIV acquisition risk associated with alcohol use and condom-less sex with multiple partners as facilitators driving PrEP initiation. They anticipated social support from family members, their main sexual partner and close friends for their PrEP use, and discussed other men as important sources of support for PrEP initiation. Nearly all men expressed positive views of people using PrEP. Participants believed HIV testing would be a barrier for men interested in accessing PrEP. Men recommended that access to PrEP be convenient, rapid, and community-based (i.e., not clinic-based). DISCUSSION: Self-perceived risk for HIV acquisition was a major facilitator for men's PrEP initiation. Although men expressed positive perceptions of PrEP users, they noted that HIV testing may be a barrier to PrEP initiation. Finally, men recommended convenient access points to facilitate PrEP initiation and sustained use. Gender-responsive interventions tailored to men's needs, wants, and voices will facilitate their uptake of HIV prevention services, and help to end the HIV epidemic.

RESUMO

Home-based service delivery has been used to improve access to HIV testing and antiretroviral initiation across sub-Saharan Africa, but it has yet to be leveraged to improve pre-exposure prophylaxis (PrEP) uptake. We interviewed 37 adolescent girls and young women (AGYW) in Eastern Cape, South Africa to explore why they chose to initiate PrEP or not following home-based HIV testing and referral for PrEP, and what influenced time to PrEP initiation. Participants reported that home visits provided a source of trusted information and a way to involve family members in their PrEP initiation decisions, motivating some to start PrEP. AGYW who initiated PrEP were more likely to qualitatively perceive themselves to be at high risk for HIV compared with those who never initiated PrEP. Integrating home-based HIV testing with PrEP education and referral may be a valuable way to reduce familial barriers and boost PrEP uptake among AGYW in South Africa.

RESUMO

BACKGROUND: In this study, the factors that influence the choice of place of delivery among expectant mothers in both rural and urban settings in the northern part of Ghana were identified and compared using the conceptual framework provided by Thaddeus and Maine. METHODS: A mixed-method study was used to examine expectant mothers and their responses related to factors that affect their choice of place of delivery through a concurrent triangulation using health professional interviews and a detailed participant survey. The sample consisted of 552 expectant mothers between the ages of 15 and 49 years. Individual interviews were conducted with 8 health professionals. There was also a focus group discussion with randomly selected pregnant women and lactating mothers. Themes were generated through open coding of the interview data, while multiple regression was performed to identify the factors associated with choice of place of delivery. RESULTS: Major preference (60.1%) was for home delivery among rural dwellers compared to 20.7% for urban participants. Statistically significant variables affecting the choice of place of delivery among study participants were found to be educational background, the experience of previous deliveries, the attitude of hospital staff toward pregnant women during labor, and frequency of accessing antenatal care. CONCLUSION: Majority of rural women prefer home delivery to facility delivery which is the opposite of the trend observed among urban women. The study's implications may lead to positive change where stakeholders develop and implement policies to promote health facility delivery for expectant mothers in Ghana.

RESUMO

OBJECTIVE: The effectiveness of household contact investigations is limited by low referral uptake for clinic-based TB testing by symptomatic household contacts. We qualitatively investigated the acceptability and perceived benefits of home-based TB testing using a portable GeneXpert-I instrument (GX-I) in an urban South African township. METHODS: In-depth interviews were conducted with household contacts tested and those that observed testing. Semi-structured interviews explored household contact's understanding of TB, perceptions of the GX-I device and testing procedures, confidentiality, willingness to refer others, and views on home- vs. clinic-based testing. Focus group discussions with home-based TB testing implementing staff assessed operational considerations for scale-up. Data were analysed using a constant comparison approach to qualitatively evaluate the acceptability and feasibility of home-based TB testing. RESULTS: Thirty in-depth interviews and two focus group discussions were conducted. Observing one's own sputum being tested resulted in an emergent trust in home-based TB testing, the GX-I device and one's test results. Home-based TB testing was considered convenient, helped to overcome apathy towards testing and mitigated barriers to clinic-based testing. Perceptions that home-based TB testing contributes to improved household and community health resulted in an emergent theme of alleviation of health insecurities. Operational concerns regarding inadvertent disclosure of one's diagnosis to household members and time spent in people's homes were identified. CONCLUSIONS: Home-based TB testing was acceptable and feasible. Individuals expressed belief in the machine by being able to witness the testing process. Though most themes mirrored qualitative studies of home-based HIV testing, the alleviation of health insecurities theme is unique to home-based TB testing. Future research must evaluate the impact of home-based TB testing on case finding yield, time-to-treatment initiation and household outcomes.


OBJECTIF: L'efficacité des enquêtes sur les contacts familiaux est limitée par le faible taux de respect de l'orientation pour le dépistage de la tuberculose (TB) en clinique par les contacts familiaux symptomatiques. Nous avons investigué qualitativement l'acceptabilité et les avantages perçus du dépistage de la TB à domicile à l'aide d'un dispositif portable GeneXpert-I (GX-I) dans une ville urbaine sud-africaine. MÉTHODES: Des entretiens approfondis ont été menés avec des contacts familiaux testés et ceux qui ont observé la pratique des tests. Des entretiens semi-structurés ont permis d'explorer la compréhension de la TB par les contacts familiaux, les perceptions sur le dispositif GX-I et les procédures de test, la confidentialité, la volonté de référer d'autres personnes et les opinions sur le dépistage à domicile ou en clinique. Des discussions de groupe focalisées avec le personnel chargé de la mise en œuvre du dépistage de la TB à domicile ont évalué les considérations opérationnelles pour le déploiement. Les données ont été analysées en utilisant une approche de comparaison constante pour évaluer qualitativement l'acceptabilité et la faisabilité du dépistage de la TB à domicile. RÉSULTATS: Trente entretiens approfondis et deux discussions de groupe ont été menés. L'observation de ses propres expectorations testées a conduit à une émergente de confiance dans le dépistage de la TB à domicile, le dispositif GX-I et les résultats des tests. Le dépistage de la TB à domicile était considéré comme pratique, aidait à surmonter l'apathie envers le dépistage et atténuait les obstacles au dépistage en clinique. La perception selon laquelle le dépistage de la TB à domicile contribue à l'amélioration de la santé des ménages et de la communauté a donné lieu à l'émergence du thème de la réduction des insécurités sanitaires. Des préoccupations opérationnelles concernant la divulgation par inadvertance de son diagnostic aux membres du ménage et le temps passé au domicile des personnes ont été identifiées. CONCLUSION: Le dépistage de la TB à domicile était acceptable et faisable. Les individus ont exprimé leur croyance en la machine en étant en mesure d'assister au processus de test. Bien que la plupart des thèmes reflètent des études qualitatives sur le dépistage du VIH à domicile, le thème de l'atténuation des insécurités sanitaires est unique au dépistage de la TB à domicile. Les recherches futures doivent évaluer l'impact du dépistage de la TB à domicile sur le rendement de la recherche des cas, le délai de mise en route du traitement et les résultats au sein des ménages.

RESUMO

Pre-exposure prophylaxis (PrEP) in pregnancy can reduce HIV incidence and vertical transmission. Healthcare providers (HCPs) play a critical role in delivering PrEP in antenatal care but little is known about HCP knowledge and attitudes about PrEP in pregnancy. We conducted a qualitative study in two healthcare facilities to assess HCPs' PrEP knowledge and perspectives relating to HIV prevention in pregnant women. Between January-March'19, we administered in-depth interviews among antenatal HCPs. We utilized a constant comparison approach to identify major qualitative findings. We enrolled 35 female HCPs (median age=43yrs. Fewer than half of HCPs had heard of PrEP before. Of those who had heard of PrEP, most felt that it was safe to take during pregnancy. Most HCPs described inaccurate PrEP knowledge regarding effectiveness, and most who knew about PrEP lacked clinical detail. HCPs highlighted important potential barriers to maternal PrEP use including: fear that PrEP may be unsafe, or belief that women must talk to partners/parents before initiating PrEP. Facilitators include good knowledge about serodiscordancy and vulnerability to seroconversion in pregnancy and desire to help women gain control overHIV prevention. We recommend integrating PrEP training into HIV testing and PMTCT nurse training to improve counseling and maternal PrEP delivery.

RESUMO

BACKGROUND: Sexually transmitted infections (STIs) during pregnancy result in neonatal morbidity and mortality, and may increase mother-to-child-transmission of HIV. Yet the World Health Organization's current syndromic management guidelines for STIs leaves most pregnant women undiagnosed and untreated. Point-of-care (POC) diagnostic tests for STIs can drastically improve detection and treatment. Though acceptable and feasible, poor medication adherence and re-infection due to lack of partner treatment threaten the programmatic effectiveness of POC diagnostic programmes. METHODS: To engender patient-provider trust, and improve medication adherence and disclosure of STI status to sexual partners, we trained study nurses in compassionate care, good clinical practices and motivational interviewing. Using qualitative methods, we explored the role patient-provider communications may play in supporting treatment adherence and STI disclosure to sexual partners. Nurses were provided training in motivational interviewing, compassionate care and good clinical practices. Participants were interviewed using a semi-structured protocol, with domains including STI testing experience, patient-provider communication, and HIV and STI disclosure. Interviews were audio-recorded, transcribed and analyzed using a constant comparison approach. RESULTS: Twenty-eight participants treated for Chlamydia trachomatis (CT), Trichomonas vaginalis (TV), and/or Neisseria gonorrhea (NG) were interviewed. Participants described strong communications and trusting relationships with nurses trained in patient-centered care training and implementing POC STI diagnostic testing. However, women described a delayed trust in treatment until their symptoms resolved. Women expressed a limited recall of their exact diagnosis, which impacted their ability to fully disclose their STI status to sexual partners. CONCLUSIONS: We recommend implementing patient health literacy programmes as part of POC services to support women in remembering and disclosing their specific STI diagnosis to sexual partners, which may facilitate partner treatment uptake and thus decrease the risk of re-infection.

RESUMO

Given the high HIV prevalence for men who have sex with men (MSM) and transgender women in South Africa, there is limited understanding of social determinants that influence antiretroviral treatment (ART) adherence. Although universal testing and treatment (UTT) is available, ART adherence remains suboptimal. We conducted focus groups with MSM and transgender women in order to understand factors influencing their ART adherence in Mpumalanga, South Africa. All focus groups were audio-recorded, transcribed and translated for analysis using a constant comparison approach, guided by the concept of Therapeutic Citizenship. We found there is medical mistrust of ART based on differing interpretations of HIV cure that may influence treatment adherence behaviors within social networks, and relationship desire had a significant influence on optimal ART adherence. Our findings suggest that clinics must provide interventions that integrate HIV disclosure and relationship skill-building to support optimal ART adherence for MSM and transgender women under UTT.

RESUMO

Background Sexually transmissible infections (STI) may increase the risk of mother-to-child transmission (MTCT) of HIV. However, diagnostic testing and targeted treatment of STI (STI-TT) during pregnancy is not standard care in South Africa. METHODS: A qualitative study was nested in a STI-TT intervention to investigate motivating and enabling factors associated with STI test results disclosure to sexual partners. A semi-structured interview protocol covered partner communication, HIV and STI disclosure, financial security and relationships dynamics. Interviews were conducted in participants' preferred language, audio-recorded, transcribed into English and analysed using a constant comparison approach. The study was conducted in two townships in Pretoria, South Africa. RESULTS: Twenty-eight HIV-positive pregnant women were interviewed. Based on the interviews, two disclosure experiences for women were identified - those with vulnerable experiences and those with self-enabling experiences within their partnerships. Vulnerable women discussed intimate partner violence (IPV) and fear of relationship dissolution as factors influencing their test result disclosure. Self-enabled women discussed their ability to talk with their partners about STI and HIV infections and the influence of multiple concurrent partnerships in the acquisition of HIV/STIs. Both groups of women were concerned about men's health behaviours, and all cited the health and development of their unborn child as a key motivator for test result disclosure. CONCLUSIONS: Improved counselling and support for pregnant women to disclose their STI test results to their partners may improve the impact of STI diagnostic testing during pregnancy by improving partner treatment uptake and thus reducing the risk of re-infection.

RESUMO

Excessive alcohol consumption has been shown to increase HIV risk for men who have sex with men (MSM) and compromise HIV prevention behaviors. However, there is limited contextual understanding of alcohol use for MSM in rural sub-Saharan African settings, which can inform and direct HIV interventions. Applying an adaptation of PhotoVoice, we worked with 35 HIV-positive MSM who created photo-essays about alcohol and HIV in Mpumalanga. A semi-structured protocol was used in focus group discussions that were audio-recorded, translated and transcribed. Transcript data and visual data of 24 photo-essays were analyzed using a constant comparison approach. We found that participants used alcohol to build and sustain social networks, meet sexual partners, and enhance sexual experience. Excessive alcohol use was common, which was associated with increased HIV risk behaviors within a community of MSM who maintained multiple partnerships. Our study suggests that HIV interventions need to address excessive alcohol use to mitigate the associated HIV risk at both the individual and community levels.

RESUMO

We explored to whom rural men who have sex with men (MSM) disclose their sexual identity and HIV status in Mpumalanga, South Africa. Participants were recruited using a modified snowball sampling method in order to complete a questionnaire. Descriptive and logistic regression analyses were conducted. There were 47 participants of whom 22 self-reported as HIV-positive. Most participants disclosed their sexuality and HIV status to immediate family members and gay-identified friends. We found that the longer someone had identified as MSM, the more likely they were to be HIV-positive and not go to clinic. Education and employment modified these findings. This study presents a broader picture of MSM in this rural African setting: that they do disclose their sexuality and HIV status to others in their community. However, more research is needed to develop these measures. We need to assess how long participants identify as MSM, how long they have been HIV-positive, and to whom they have disclosed these aspects of their lives to inform HIV prevention and treatment interventions for MSM in rural settings.

RESUMO

Global health training programs for undergraduate students are expanding in the United States, which includes Minority-Serving Institutions (MSIs), but capacity building is needed at MSIs to develop career pathways into the field, especially for those institutions that serve low-income students who live in communities with high health disparities. Often, global health pathways begin by building a global lens through the examination of local health issues coupled with international educational experiences. This approach is limited for students who come from low-income settings with limited funding for international experiences, and as a result, may not see the feasibility of a global health career. However, there may be opportunity in harnessing student motivations and participatory research methods to build interest in a global health career. This article outlines the course, Fundamentals of Global Health, offered at a public MSI in the Bronx. The course was grounded in the Geo-Social Pathway Framework and utilized PhotoVoice to engage students in individual research projects. A constant comparison method was used to analyze papers, photos, reflections, and presentations in order to identify themes. Analysis of course materials submitted by students suggests that they were motivated to examine health disparities using PhotoVoice and that they focused their research projects on their family and community health disparities, or aligned with educational or professional goals to address their community health needs. This course model may inform future training in global health for students at MSIs, but community-based participatory research priority funding is needed to sustain global health at these key institutions.

RESUMO

Rural South African men who have sex with men (MSM) are likely to be underserved in terms of access to relevant healthcare and HIV prevention services. While research in urban and peri-urban MSM populations has identified a range of factors affecting HIV risk in South African MSM, very little research is available that examines HIV risk and prevention in rural MSM populations. This exploratory study begins to address this lack by assessing perceptions of HIV risk among MSM in rural Limpopo province. Using thematic analysis of interview and discussion data, two overarching global themes that encapsulated participants' understandings of HIV risk and the HIV risk environment in their communities were developed. In the first theme, "community experience and the rural social environment", factors affecting HIV risk within the broad risk environment were discussed. These included perceptions of traditional value systems and communities as homophobic; jealousy and competition between MSM; and the role of social media as a means of meeting other MSM. The second global theme, "HIV/AIDS knowledge, risk and experience", focused on factors more immediately affecting HIV transmission risk. These included: high levels of knowledge of heterosexual HIV risk, but limited knowledge of MSM-specific risk; inconsistent condom and lubricant use; difficulties in negotiating condom and lubricant use due to uneven power dynamics in relationships; competition for sexual partners; multiple concurrent sexual partnerships; and transactional sex. These exploratory results suggest that rural South African MSM, like their urban and peri-urban counterparts, are at high risk of contracting HIV, and that there is a need for more in-depth research into the interactions between the rural context and the specific HIV risk knowledge and behaviours that affect HIV risk in this population.

RESUMO

Using data from four sites in three African countries, this community randomized study examined the association between childhood sexual and/or physical abuse (CSA and/or CPA) and HIV disclosure, HIV-related stigma, stress, and social support among adults with and without a history of abuse. A history of abuse among men was associated with higher levels of adult-reported stress and HIV-related stigma, and with significantly lower rates of HIV test result disclosure to current partners. Women with a history of CSA and/or CPA had significantly higher perceived stigma, discrimination and stress. Although childhood abuse was significantly associated with adult stress and stigmatization, participants with histories of CSA and/or CPA also reported significantly higher perceived social support compared to people without such experiences. These findings may reflect support received in response to disclosure of CSA or CPA or emotional ambivalence in relationships that have been found to be associated with child abuse. We conclude that it is critical for HIV prevention interventions to advocate for the primary prevention of child abuse, for early identification of adolescents and adults who report experiencing childhood abuse, and to address stigma and stress-related attitudinal, behavioral and relationship difficulties experiences as an aftermath of early abuse that increase their risk of HIV.

RESUMO

BACKGROUND: Over the past decade, the University of Nairobi (UoN) has increased the number of enrolled medical students threefold in response to the growing need for more doctors. This has resulted in a congested clinical training environment and limited opportunities for students to practice clinical skills at the tertiary teaching facility. To enhance the clinical experience, the UoN Medical Education Partnership Initiative Program Undertook training of medical students in non-tertiary hospitals around the country under the mentorship of consultant preceptors at these hospitals. This study focused on the evaluation of the pilot decentralized training rotation. METHODS: The decentralized training program was piloted in October 2011 with 29 fourth-year medical students at four public hospitals for a 7-week rotation. We evaluated student and consultant experiences using a series of focus group discussions. A three-person team developed the codes for the focus groups and then individually and anonymously coded the transcripts. The team's findings were triangulated to confirm major themes. RESULTS: Before the rotation, the students expressed the motivation to gain more clinical experience as they felt they lacked adequate opportunity to exercise clinical skills at the tertiary referral hospital. By the end of the rotation, the students felt they had been actively involved in patient care, had gained clinical skills and had learned to navigate socio-cultural challenges in patient care. They further expressed their wish to return to those hospitals for future practice. The consultants expressed their motivation to teach and mentor students and acknowledged that the academic interaction had positively impacted on patient care. DISCUSSION: The decentralized training enhanced students' learning by providing opportunities for clinical and community experiences and has demonstrated how practicing medical consultants can be engaged as preceptors in students learning. This training may also increase students' ability and willingness to work in rural and underserved areas.

RESUMO

The quality of cancer care delivery varies across different regions of Ghana, highlighting the need for improved access to quality healthcare services. Telemedicine has emerged as a promising solution to address this disparity, as it can reduce costs and improve access to healthcare services for cancer patients in remote areas. Despite the widely reported benefits of telemedicine, its adoption in low-resource settings has been slow due to several challenges. This study explores strategies for incorporating telemedicine into the current healthcare system in Ghana for the benefit of all patients especially those diagnosed with cancer. The study also highlights the current challenges and opportunities associated with the implementation and utilisation of telemedicine in Ghana. This research was a cross-sectional study conducted in Accra, Ghana that adopted a mixed-methods approach. Participants were selected through multi-stage probability sampling. Quantitative data were collected via a survey whereas qualitative data were obtained by means of in-depth interviews and focus group discussions among healthcare professionals, patients and key stakeholders in the telemedicine industry. The Statistical Program for the Social Sciences (version 21) was used to assemble, analyse and display the research data. The major challenges discussed centered on high initial investment costs, privacy and security concerns, poor internet connectivity, insufficient infrastructure and training of healthcare providers as well as the resistance to change among healthcare professionals. The study contributes to the understanding of telemedicine adoption in Ghana with findings underscoring the potential to address healthcare challenges while highlighting the need to overcome implementation obstacles. The study findings also provide valuable insights for policymakers, healthcare institutions and stakeholders to enhance telemedicine adoption in Ghana.

RESUMO

Cervical cancer (CC) is one of the leading causes of cancer-related deaths among females in Ghana. Despite the magnitude of the public health challenge posed by CC in Ghana, survival data as well as reported incidence and mortality rates are primarily based on studies conducted in the capital city of the country. Even though age at diagnosis is known to affect the overall survival of CC patients, the role of this factor in the prognosis of CC patients in Ghana has not been sufficiently explored. The aim of this study was to determine the 5-year survival rate of Ghanaian woman treated for CC at a large tertiary healthcare facility in Ghana. This research was a single-institution-based quantitative retrospective cohort study conducted among patients with histopathologically confirmed CC. Clinical and socio-demographic data were retrieved from patients' medical records. Data analysis was done using the Statistical Package for the Social Sciences software version 23. Kaplan Meier curves were used to present the survival rates and median survival time. The peak age at diagnosis was between 45 and 80 years with the modal age group of patients between 75 and 80 years. The mean age at diagnosis was 63.3 ± 15.7 years ranging from 27 to 104 years. The overall survival rates at 1, 3 and 5 years were 76.5%, 51.5% and 32.4%, respectively. The median survival time was 65.8 months. Age < 50 years was associated with higher survival estimates than age >50 years. The 5-year overall survival rate of CC patients reported in this study (32.4%) is relatively low compared with countries in the developed world but like previous reports at other healthcare facilities in Ghana as well as in other underdeveloped countries.

RESUMO

Introduction: above the age of 40, women are advised to begin breast examinations and screenings for early detection of breast cancer. The average glandular dose (AGD) provides dosimetric information about the quantity of radiation received by the mammary glands during mammographic exposures. There is, therefore, the need to analyse the radiation dose received by patients presenting for mammography examinations. Methods: a retrospective cross-sectional design was carried out on the data of 663 participants, conveniently sampled between the months of July 2021 and June 2022. Paired T-test was used to compare imaging parameters for cranio-caudal (CC), medio-lateral (ML), automatic exposure control (AEC), manual exposure control (MEC), and left and right breast. Pearson´s correlation was used to test for relationship between imaging parameters and AGD. Results: the mean AGD per exposure was 1.9 ± 0.7 mGy for CC projections and 2.3 ± 1.2 mGy for ML projections. The mean AGD per examination for the study was 4.1 ± 1.4 mGy. A positive correlation was found between AGD per examination and exposure factors (tube loading and tube voltage), compressed breast thickness, and compression force. Patient age had no statistically significant relationship with the AGD per examination. Conclusion: average glandular dose (AGD) was consistent with other findings in literature studies. It was also observed that MEC yielded lower AGD per exposure values than AEC. There was no significant difference in the mean AGD per exposure for left and right breasts.
