Delays in seeking, reaching and access to quality cancer care in sub-Saharan Africa: a systematic review

Clinicopathological features and management of obstructive jaundice at Queen Elizabeth Central Hospital, Malawi. A retrospective cohort analysis

Introduction

The diagnosis of obstructive jaundice (OJ) is a challenge and is often made late especialy in low-resource settings. There is a paucity of data on the aetiology and prognosis of patients with obstructive jaundice in Malawi and Sub-Saharan Africa. The objective of this study was to determine the aetiology, clinical presentations, and short-term treatment outcomes of patients managed for OJ in Malawi.

Methodology

A review of case notes of all patients admitted with a clinical diagnosis of OJ from 2012 to 2022 was done. We reviewed the clinical presentation, laboratory findings, management, intra and post-operative complications, and patient outcomes. Data was entered into an Excel spreadsheet and analysed using SPSS version 25.

Results

Of 26,796 patient admissions, 5339 (19.9%) were for non-trauma abdominal symptoms, of which 164 (0.6% of surgical admissions and 3% of abdominal symptoms) were for obstructive jaundice. Ages varied from 16 to 89 years. Females were 45 (58.4 %) of the population. The commonest presenting complaint was jaundice followed by abdominal pain and distention. The mean duration of symptoms at presentation was 8.5 weeks. The most frequent imaging modality was abdominal ultrasound 50(65 %). Twenty-six patients (33.8 %) were discharged with a diagnosis of obstructive jaundice of undetermined pathogenesis. The commonest diagnosis was pancreatic cancer 20(26.0 %) followed by Choledocholithiasis11(14.3 %). Patients younger than 50 years had the same likelihood of presenting with cancer as those older than 50 years.

Conclusion

It is important to have a high index of suspicion in all adult patients presenting with obstructive jaundice as patients younger than 50 years have a similar risk of malignancy as older patients.

Hypertensive crisis and its predictors in Africa: Systematic review and meta-analysis, 2024

Introduction

Hypertensive crises are a leading cause of visits to emergency departments, carrying grave health implications. A significant number of patients presenting with these crises have a known history of hypertension.

Objective

The aim of this systematic review and meta-analysis is to examine the combined prevalence of hypertensive crises among individuals with either a history of hypertension or unknown status (newly diagnosed with a hypertensive crisis).

Methods

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered with the Prospective Register of Systematic Reviews (PROSPERO). Research databases, including PubMed, Embase, Scopus, Africa Index Medicus, Science Direct, HINARI, and Google Scholar, were systematically searched. Study quality was evaluated using the Newcastle-Ottawa Scale, while publication bias was explored through Egger's regression test, funnel plots, and sensitivity analyses. Data collection adhered to the Joanna Briggs Institute (JBI) format. Meta-analysis was performed using STATA version 17, employing the random-effects DerSimonian-Laird model.

Results

Amongst the 15 studies analyzed, the application of the random-effects DerSimonian-Laird statistical model indicated that the prevalence of hypertensive crisis was determined to be 9.09 %, with a 95 % confidence interval (CI) ranging from 7.41 % to 10.77 %. Factors such as poor medication adherence (POR 5.00; 95 % CI: 3.61, 6.93), patients with comorbidities (POR 4.73; 95 % CI: 3.29, 6.80), patients with a history of hypertension (POR 5.64; 95 % CI: 4.57, 6.94), patients aged >65 (POR 2.77; 95 % CI: 2.16, 6.59), and excessive alcohol intake (POR 5.01; 95 % CI: 3.82, 6.58) were associated with higher odds of hypertensive crisis.

Conclusion

The findings indicate a markedly higher incidence of hypertensive crisis among hospital-presenting patients in Africa. Factors such as medication non-adherence, co-existing comorbidities, historical hypertension, being over 65, and alcohol misuse significantly contribute to this condition. These insights call for a comprehensive healthcare strategy that targets both the management of hypertension and its complications, aiming to improve the overall health outcomes of affected patients.

Impact of Medical Oncology-Focused Quality Programs on Cancer Care Around the World

Quality cancer care is efficient, accessible, coordinated, and evidence-based. Recognizing the necessary key components, development of pathways and guidelines to incorporate these key domains, and finally respectful adaptation to cultural differences can ensure that cancer care globally is of the highest quality. This quality care should be judged not only on how it optimizes health outcomes for patients, but also its impact on the care providers and the global community.

Access to oncology care in Mali: a qualitative study on breast cancer

BACKGROUND

Breast cancer is the most common cancer in terms of incidence and mortality among women worldwide, including in Africa, and a rapid increase in the number of new cases of breast cancer has recently been observed in sub-Saharan Africa. Oncology is a relatively new discipline in many West African countries, particularly Mali; thus, little is known about the current state of cancer care infrastructure and oncology practices in these countries.

METHODS

To describe the challenges related to access to oncology care in Mali, we used a qualitative approach, following the Consolidated Criteria for Reporting Qualitative Research (COREQ). Thirty-eight semistructured interviews were conducted with health professionals treating cancer in Mali (n = 10), women with breast cancer (n = 25), and representatives of associations (n = 3), and 40 participant observations were conducted in an oncology unit in Bamako. We used the theoretical framework on access to health care developed by Levesque et al. a posteriori to organise and analyse the data collected.

RESULTS

Access to oncology care is partly limited by the current state of Mali's health infrastructure (technical platform failures, repeated strikes in university hospitals, incomplete free health care and the unavailability of medicines) and exacerbated by the security crisis that has been occurring the country since 2012. The lack of specialist doctors, combined with limited screening campaigns and a centralised and fragmented technical platform in Bamako, is particularly detrimental to breast cancer treatment. Women's lack of awareness, lack of information throughout the treatment process, stereotypes and opposition to amputations all play a significant role in their ability to seek and access quality care, leading some women to therapeutically wander and others to want to leave Mali. It also leaves them in debt and jeopardises the future of their children. However, the high level of trust in doctors, the involvement of international actors, the level of social support and the growing influence of civil society on the issue of cancer also represent great current opportunities to fight cancer in Mali.

CONCLUSION

Despite the efforts of successive Malian governments and the commitment of international actors, the provision of health care is still limited in the country, entrenching global inequalities in women's bodies.

Barriers to optimal management of cancer pain in sub-Saharan Africa: a scoping review

Background

Although cancer is a significant issue in sub-Saharan Africa, and cancer pain is prevalent, there is insufficient data and research on the barriers to cancer pain management. Even in countries where evidence exists, few studies explore the links between these barriers, which makes it difficult to implement system-wide approaches to address them.

Methods

The search strategy was developed and conducted on databases including MEDLINE, Embase and Web of Science to identify peer-reviewed studies. Then, these retrieved studies were screened systematically to select papers that had met pre-specified criteria. The barriers were categorised into patient-, health professional- and health system-level domains. Then, the quality of the included papers was assessed using the mixed methods appraisal tool. Finally, a narrative synthesis was utilised to summarise the findings.

Results

Fourteen relevant articles from 19 sub-Saharan African countries were included in the scoping review. All the studies highlighted barriers to optimal cancer pain management. Healthcare system-related domains had the most frequently reported barriers. Approximately half of the included studies met 100% of the methodological quality criteria in the critical appraisal.

Conclusion

Improving pain management for cancer patients in sub-Saharan Africa requires further high-level research evidence on regulatory policies and interventional strategies, especially at the health system level, as most barriers to cancer pain treatment essentially stem from the healthcare system.

Socioeconomic status significantly impacts childhood cancer survival in South Africa

BACKGROUND AND AIMS

Significantly discrepant survival rates have been documented in single disease childhood cancer cohorts in South Africa; those from higher socioeconomic groups were shown to have a significantly lower risk of death than those from less affluent households. This study aimed to determine the impact of socioeconomic status (SES) on childhood cancer survival using pooled South African data.

METHODS

Five databases spanning January 2000 to December 2021 were interrogated. SES status was assigned based on a public sector annual household income classification. H0 households (formally unemployed) received free healthcare. H1, H2 and H3 (annual income > United States Dollar [USD] 19,000) households paid for healthcare relative to their income. The Spearman test assessed correlations between SES and disease stage in patients with solid tumours. Hazard ratios were determined using Cox regression modelling. The Kaplan-Meier procedure estimated overall survival (OS).

RESULTS

A total of 1598 children were eligible for analysis; 1269 had a solid tumour with a negative correlation between SES and stage (Spearman rho = -.178; p < .001). Patients with solid tumours and lower SES showed proportionately higher numbers of stage III and IV disease (p < .01). This proportion decreased with higher SES categories. In the multivariate analyses adjusted for sex, age, tumour type and stage, higher SES was associated with lower mortality risk (p < .001), indicating that the impact of SES on survival was in excess of any effect that could be explained by lower stage disease alone. There was a strong positive correlation between race and SES (Fisher's exact tests, p < .001) across all groups and all SES strata. Five-year OS was 85.3% in children from H3 households versus 46.3% in children from H0 households (p < .001).

CONCLUSION

SES significantly impacts childhood cancer survival for children with solid tumours in South Africa. SES is a robust surrogate for race in South Africa as a prognostic metric of disease outcome in childhood cancer. Advocacy to increase social support for impoverished patients is essential to achieve equitable improvements in outcomes treated with standardised national treatment guidelines.

Moving forward through consensus: a national Delphi approach to determine the top research priorities in prostate cancer in Uganda

OBJECTIVE

To identify key areas for research in prostate cancer (PC) in the Ugandan context by establishing the major health system, socioeconomic and clinical barriers to seeking, reaching and receiving high-quality cancer care.

DESIGN

Modified Delphi Technique.

SETTING

Government and private-not-for-profit hospitals.

METHODS

We applied a two-stage modified Delphi technique to identify the consensus view across cancer experts. In round 1, experts received a questionnaire containing 21 statements drawn from a systematic review identifying the reason for the delay in accessing cancer care. Each statement was scored out of 20. Statements scoring ≥15 from over 70% of participants were prioritised for inclusion while statements for which <30% of participants gave a score of ≥15 were excluded. Sixteen statements were included in round 2 as they did not receive consensus for inclusion or exclusion.

RESULTS

We found that the top six research priority areas arise from challenges including: (1) lack of diagnostic services-ultrasound, laboratory tests and biopsy facilities; (2) high costs of services, for example, surgery, radiotherapy, hormone therapy are unaffordable to most patients, (3) lack of essential medicines, (4) limited radiotherapy capacity, (5) lack of awareness of cancer as a disease and low recognition of symptoms, (6) low healthcare literacy. The lack of critical surgical supplies, high diagnostic and treatment costs were ranked highest in order of importance in round 1. Round 2 also revealed lack of diagnostic services, unavailability of critical medicines, lack of radiotherapy options, high costs of treatments and lack of critical surgical supplies as the top priorities.

CONCLUSION

These research priority areas ought to be addressed in future research to improve prompt PC diagnosis and care in Uganda. There is need to improve the supply of high-quality affordable anticancer medicines for PC patients so as to improve the survivorship from the cancer.

Cross-Cultural Adaptation and Psychometric Properties of the Swahili Version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-BR45 among Breast Cancer Patients in Tanzania

Breast cancer is the most frequent cancer in women in Africa and contributes to premature death and poor quality of life. This study aimed to determine the validity, reliability, and psychometric properties of the Swahili version of EORTC QLQ-BR45 among women with breast cancer in Tanzania. A cross-sectional study design with non-probability convenience sampling was employed. Data were collected in two tertiary hospitals and one national cancer institute; 414 participants completed the EORTC-QLQ-C-30 and EORTC-QLQ-BR45. The reliability of QLQ-BR45 was measured using Cronbach's alpha and McDonald's Omega coefficients. The factor structure of EORTC QLQ-BR45 was assessed using confirmatory factor analysis. The internal consistencies for the five dimensions were all above 0.7 indicating satisfaction, except for systemic therapy side effects with a marginal value of 0.594 and significant correlations between the dimensions of QLQ-C30 and BR45. The final model fit well to the data, with the comparative fit index = 0.953, Tucker-Lewis index = 0.947, root mean square error of approximation = 0.041 (90% CI: 0.035, 0.046), and standardized root mean square residual = 0.072. In conclusion, the QLQ BR45 Swahili version displayed good reliability, validity, and psychometric properties and can be used in Swahili-speaking Sub-Saharan countries.
