The role of digital surveillance during outbreaks: the Ghana experience from COVID-19 response.

Over the years, Ghana has made notable strides in adopting digital approaches to address societal challenges and meet demands. While the health sector, particularly the disease surveillance structure, has embraced digitization to enhance case detection, reporting, analysis, and information dissemination, critical aspects remain to be addressed. Although the Integrated Disease Surveillance and Response (IDSR) structure has experienced remarkable growth in digitization, certain areas require further attention as was observed during the COVID-19 pandemic. Ghana during the COVID-19 pandemic, recognized the importance of leveraging digital technologies to bolster the public health response. To this end, Ghana implemented various digital surveillance tools to combat the pandemic. These included the 'Surveillance Outbreak Response Management and Analysis System (SORMAS)', the digitalized health declaration form, ArcGIS Survey123, Talkwalker, 'Lightwave Health information Management System' (LHIMS), and the 'District Health Information Management System (DHIMS)'. These digital systems significantly contributed to the country's success in responding to the COVID-19 pandemic. One key area where digital systems have proved invaluable is in the timely production of daily COVID-19 situational updates. This task would have been arduous and delayed if reliant solely on paper-based forms, which hinder efficient reporting to other levels within the health system. By adopting these digital systems, Ghana has been able to overcome such challenges and provide up-to-date information for making informed public health decisions. This paper attempts to provide an extensive description of the digital systems currently employed to enhance Ghana's paper-based disease surveillance system in the context of its response to COVID-19. The article explores the strengths and challenges or limitations associated with these digital systems for responding to outbreaks, offering valuable lessons that can be learned from their implementation.

Using drones to transport suspected COVID-19 samples; experiences from the second largest testing centre in Ghana, West Africa.

BACKGROUND: The declaration of COVID-19 as a pandemic on March 11 2020, by the World Health Organisation prompted the need for a sustained and a rapid international response. In a swift response, the Government of Ghana, in partnership with Zipline company, launched the use of Unmanned Automated Vehicles (UAV) to transport suspected samples from selected districts to two foremost testing centres in the country. Here, we present the experiences of employing this technology and its impact on the transport time to the second largest testing centre, the Kumasi Centre for Collaborative Research in Tropical Medicine (KCCR) in Kumasi, Ghana. METHODS: Swab samples collected from suspected COVID-19 patients were transported to the Zipline office by health workers. Information on the samples were sent to laboratory personnel located at KCCR through a WhatsApp platform to get them ready to receive the suspected COVID-19 samples while Zipline repackaged samples and transported them via drone. Time of take-off was reported as well as time of drop-off. RESULTS: A total of 2537 COVID-19 suspected samples were received via drone transport from 10 districts between April 2020 to June 2021 in 440 deliveries. Ejura-Sekyedumase District Health Directorate delivered the highest number of samples (765; 30%). The farthest district to use the drone was Pru East, located 270 km away from KCCR in Kumasi and 173 km to the Zipline office in Mampong. Here, significantly, it took on the average 39 minutes for drones to deliver samples compared to 117 minutes spent in transporting samples by road (p<0.001). CONCLUSION: The use of drones for sample transport during the COVID-19 pandemic significantly reduced the travel time taken for samples to be transported by road to the testing site. This has enhanced innovative measures to fight the pandemic using technology.

Overview of preparedness and response to COVID-19 in Ghana.

The Coronavirus disease 2019 (COVID-19) outbreak in Ghana is part of an ongoing pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The first two cases of COVID-19 were confirmed in Ghana on 12th March 2020. COVID-19 was consequently declared a Public Health Emergency of National Concern, triggering several response actions, including enhanced surveillance, case detection, case management and contact tracing, closure of borders, suspension of international flights, ban on social gatherings and closure of schools. Preparedness and response plans were activated for implementation at the national, regional, district and community levels. Ghana's Strategic approaches were to limit and stop the importation of cases; detect and contain cases early; expand infrastructure, logistics and capacity to provide quality healthcare for the sick; minimise disruption to social and economic life and increase the domestic capacity of all sectors to deal with existing and future shocks. The health sector strategic frame focused on testing, treatment, and tracking. As of 31st December 2020, a total of 535,168 cases, including 335 deaths (CFR: 0.61%), have been confirmed with 53,928 recoveries and 905 active cases. All the regions have reported cases, with Greater Accra reporting the highest number. The response actions in Ghana have seen high-level political commitment, appropriate and timely decisions, and a careful balance of public health interventions with economic and socio-cultural dynamics. Efforts are ongoing to intensify non-pharmaceutical interventions, sustain the gains made so far and introduce COVID-19 vaccines to reduce the public health burden of the disease in Ghana. FUNDING: None declared.

Implementation of a percutaneous core needle biopsy training program: results from the University of Michigan-Komfo Anokye Teaching Hospital breast cancer research partnership.

PURPOSE: To describe a training program in percutaneous core needle biopsy implemented in conjunction with a breast cancer research collaboration between the University of Michigan (UM) and the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. METHODS: In July 2007 a Ghana-based training program for performance of core needle biopsy was jointly coordinated by the UM and KATH principal investigators (L.N. and B.A.). This course required less than 1 week for implementation. RESULTS: Following the training course (July 2007 through August 2008), 82 core needle biopsies of breast masses were performed at KATH. Of these, 56 had tissue specimens available for review at UM for comparison with KATH primary pathology reports. Forty-six of the 56 UM-reviewed cases (82%) had a KATH diagnosis of breast cancer; UM pathology review was in agreement with the cancer diagnosis in all 46 cases (100%). Ten of the 56 UM-reviewed cases (18%) had a KATH diagnosis of benign fibroadenoma/fibrocystic breast tissue; UM review was concordant in all ten cases (100% concordance for benign lesions). For the remaining 26 procedures we were unable to retrieve either the KATH pathology report or tissue blocks for UM review. DISCUSSION: The design and implementation of appropriate diagnostic biopsy programs is important for delivery of high-quality, efficient breast cancer care in developing nations. This study demonstrates a successful 1-week training program in percutaneous core needle biopsy for a multidisciplinary group of physicians. Further work is needed for similar programs to accurately identify and classify breast cancer internationally.

African ancestry and higher prevalence of triple-negative breast cancer: findings from an international study.

BACKGROUND: The study of breast cancer in women with African ancestry offers the promise of identifying markers for risk assessment and treatment of triple-negative disease. METHODS: African American and white American women with invasive cancer diagnosed at the Henry Ford Health System comprised the primary study population, and Ghanaian patients diagnosed and/or treated at the Komfo Anokye Teaching Hospital in Kumasi, Ghana constituted the comparison group. Formalin-fixed, paraffin-embedded specimens were transported to the University of Michigan for histopathology confirmation, and assessment of estrogen and progesterone receptors and HER-2/neu expression. RESULTS: The study population included 1008 white Americans, 581 African Americans, and 75 Ghanaians. Mean age at diagnosis was 48.0 years for Ghanaian, 60.8 years for African American, and 62.4 for white American cases (P=.002). Proportions of Ghanaian, African American, and white American cases with estrogen receptor-negative tumors were 76%, 36%, and 22%, respectively (P<.001), and proportions with triple-negative disease were 82%, 26%, and 16%, respectively (P<.001). All Ghanaian cases were palpable, locally advanced cancers; 57 (76%) were grade 3. A total of 147 American women were diagnosed as stage III or IV; of these, 67.5% (n=46) of African Americans and 44.6% (n=29) of white Americans were grade 3. Among palpable, grade 3 cancers, Ghanaians had the highest prevalence of triple-negative tumors (82.2%), followed by African Americans (32.8%) and white Americans (10.2%). CONCLUSIONS: Our study demonstrates progressively increasing frequency of estrogen receptor-negative and triple-negative tumors among breast cancer patients with white American, African American, and Ghanaian/African backgrounds. This pattern indicates a need for additional investigations correlating the extent of African ancestry and high-risk breast cancer subtypes.

Survival pattern of hemodialysis patients in Kumasi, Ghana: a summary of forty patients initiated on hemodialysis at a new hemodialysis unit.

To evaluate the survival pattern of hemodialysis patients at a dialysis unit in Kumasi, Ghana, through a retrospective (observational) study. Patients who were placed on hemodialysis at the dialysis unit at Komfo Anokye teaching hospital from October 25, 2006 to December 2007. The patients were followed from initiation of dialysis until December 31, 2007. The overall mortality was 14 (35.9%) on the incident population for the period and that for the first 90 days was 12 (32.4%) patients. Chronic glomerulonephritis was the underlying kidney disease in 35.9%. This was followed by hypertension (19.1%) and diabetes mellitus (15.4%), respectively. Cardiovascular diseases accounted for 42% of mortality. This was followed by septicemia (25%) from the access site and anemia (25%). Fifty percent of the patients were able to afford 20 sessions of hemodialysis before stopping. The most powerful predictors of survival were the duration of hemodialysis (P=0.05) and the number of hemodialysis sessions (P=0.02). Age at initiation of hemodialysis was not significant. First 90-day mortality of patients on hemodialysis is high in poor African countries. This is due partially to the late referral of patients and also the cost of the dialysis treatment. Efforts will have to be made to reduce the cost of the dialysis treatment. Reuse technology (of dialyzer, etc.) should be introduced to cut down the cost of hemodialysis. Peritoneal dialysis should also be introduced for highly motivated patients. Efforts should also be made to reduce the increasing incidence of kidney disease, and finally third-world countries should consider establishing kidney transplantation, that is cost effective.

Re-establishing a surgical pathology service in Kumasi, Ghana: case report and discussion of barriers and key elements of a successful collaboration between low- and high-resource countries.

At Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, a breakdown of technical equipment and lack of pathologists resulted in closure of the surgical pathology laboratory in 2004. At an international meeting in January 2005, 1 USA and 1 Norwegian pathologist were asked if their departments could help with the pathology problem at KATH. This article describes the proposals, the barriers encountered, and the key elements of the final successful collaboration between a low-resource and a high-resource country. The proposal to the USA hospital focused on receiving specimens for diagnosis. A detailed proposal was not developed, as several key operational barriers were identified early on, including legal issues, technical capacity issues, and staff capacity issues. The proposal to the University Hospital of North Norway (UNN) resulted in development of a 5-year plan to reestablish surgical pathology at KATH. Two KATH technicians came to UNN and trained in the histopathology laboratory for 3 months. On their return, they started producing slides at KATH. Since April 2006, weekly shipments of hematoxylin and eosin (H & E) stained slides have been sent to UNN by courier service. When needed, paraffin blocks are sent on request. In March 2006, 2 young Ghanaian physicians were received as trainees at the UNN to do full resident work and training with the aim of being approved as specialists in pathology in Ghana by 2010. Full surgical pathology service and training of new pathologists on site are expected to be reestablished at KATH by 2010.

Evaluation of a learner-designed course for teaching health research skills in Ghana.

BACKGROUND: In developing countries the ability to conduct locally-relevant health research and high quality education are key tools in the fight against poverty. The objective of our study was to evaluate the effectiveness of a novel UK accredited, learner-designed research skills course delivered in a teaching hospital in Ghana. METHODS: Study participants were 15 mixed speciality health professionals from Komfo Anokye Teaching Hospital, Kumasi, Ghana. Effectiveness measures included process, content and outcome indicators to evaluate changes in learners' confidence and competence in research, and assessment of the impact of the course on changing research-related thinking and behaviour. Results were verified using two independent methods. RESULTS: 14/15 learners gained research competence assessed against UK Quality Assurance Agency criteria. After the course there was a 36% increase in the groups' positive responses to statements concerning confidence in research-related attitudes, intentions and actions. The greatest improvement (45% increase) was in learners' actions, which focused on strengthening institutional research capacity. 79% of paired before/after responses indicated positive changes in individual learners' research-related attitudes (n = 53), 81% in intention (n = 52) and 85% in action (n = 52). The course had increased learners' confidence to start and manage research, and enhanced life-long skills such as reflective practice and self-confidence. Doing their own research within the work environment, reflecting on personal research experiences and utilising peer support and pooled knowledge were critical elements that promoted learning. CONCLUSION: Learners in Ghana were able to design and undertake a novel course that developed individual and institutional research capacity and met international standards. Learning by doing and a supportive peer community at work were critical elements in promoting learning in this environment where tutors were scarce. Our study provides a model for delivering and evaluating innovative educational interventions in developing countries to assess whether they meet external quality criteria and achieve their objectives.
