Views from Multidisciplinary Oncology Clinicians on Strengthening Cancer Care Delivery Systems in Tanzania.

BACKGROUND: In response to the increasing burden of cancer in Tanzania, the Ministry of Health, Community Development, Gender, Elderly and Children launched National Cancer Treatment Guidelines (TNCTG) in February 2020. The guidelines aimed to improve and standardize oncology care in the country. At Ocean Road Cancer Institute (ORCI), we developed a theory-informed implementation strategy to promote guideline-concordant care. As part of the situation analysis for implementation strategy development, we conducted focus group discussions to evaluate clinical systems and contextual factors that influence guideline-based practice prior to the launch of the TNCTG. MATERIALS AND METHODS: In June 2019, three focus group discussions were conducted with a total of 21 oncology clinicians at ORCI, stratified by profession. A discussion guide was used to stimulate dialogue about facilitators and barriers to delivery of guideline-concordant care. Discussions were audio recorded, transcribed, translated, and analyzed using thematic framework analysis. RESULTS: Participants identified factors both within the inner context of ORCI clinical systems and outside of ORCI. Themes within the clinical systems included capacity and infrastructure, information technology, communication, efficiency, and quality of services provided. Contextual factors external to ORCI included interinstitutional coordination, oncology capacity in peripheral hospitals, public awareness and beliefs, and financial barriers. Participants provided pragmatic suggestions for strengthening cancer care delivery in Tanzania. CONCLUSION: Our results highlight several barriers and facilitators within and outside of the clinical systems at ORCI that may affect uptake of the TNCTG. Our findings were used to inform a broader guideline implementation strategy, in an effort to improve uptake of the TNCTGs at ORCI. IMPLICATIONS FOR PRACTICE: This study provides an assessment of cancer care delivery systems in a low resource setting from the unique perspectives of local multidisciplinary oncology clinicians. Situational analysis of contextual factors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline-concordant cancer care in Tanzania and comparable settings.

Developing Research Education Groups in African Cancer Centers: The Experience in Tanzania.

Research productivity and outcomes of junior researchers are usually correlated with the degree and quality of mentorship they receive. A bottom-up approach was followed to develop a research group at the Ocean Road Cancer Institute (ORCI), the major cancer center in Tanzania, to build upon the existing clinical and research resources and institutional global collaborations. The ORCI is a clinical center focused on radio- and chemo-therapy treatment of cancer patients from all over Tanzania. In addition, ORCI has a long-standing early detection program for educating women and screening them for cervical cancer. The ORCI physicians have been exposed to cancer research for the past 20 years through non-degree and degree training in the USA and Europe. In addition, US and European groups have been conducting collaborative research and training of oncologists and graduate students at ORCI. The exposure to research through the above-listed venues motivated the clinicians at ORCI to develop their own Research Club (RC) to learn about research methods, seek independent funding, and outline a research agenda for cancer research in Tanzania. However, it seems that mentorship is needed to help the RC members apply the lessons learned from didactic teaching. Mentorship is also needed to enable the RC members to utilize the enormous clinical and epidemiologic data generated by the institutional programs for prevention, treatment, and follow up of patients. This manuscript describes the inception of the program and its achievements, limitations, and suggested opportunities for improvement as a possible model for other LMICs.

Attitudes and Barriers to Research Among Oncology Trainees in East Africa.

BACKGROUND: East Africa is one of the fastest growing regions in the world and faces a rising burden of cancer; however, few people are equipped to effectively conduct research in this area. MATERIALS AND METHODS: A 31-item questionnaire was distributed to current trainees and recent graduates of the Master in Medicine in Clinical Oncology Program at Muhimbili University of Health and Allied Sciences in Tanzania. Areas that were assessed included (a) demographic information, (b) prior research training, (c) prior and current research activities, (d) attitudes toward the importance of research, and (e) supports and barriers to inclusion of research in an oncology career path. RESULTS: A total of 30 individuals responded to the survey, of whom 53% (n = 16) were male and 70% (n = 21) identified as current trainees. Among the majority of respondents, attitudes toward research were strongly favorable. Although only 37% (n = 11) reported receiving any formal training in research methodology, 87% (n = 26) reported intentions to incorporate research into their careers. The absence of protected time for research and lack of access to research funding opportunities were identified by a majority of respondents as critical barriers. CONCLUSION: A majority of current or recent oncology trainees in Tanzania desire to incorporate research into their careers, but most also lack adequate training in research methodology and longitudinal mentorship. Our future collaboration will focus on creation of appropriate research training curriculums and fostering an environment that catalyzes interprofessional development and transforms and extends context-specific cancer research in East Africa. IMPLICATIONS FOR PRACTICE: Current and recent oncology trainees in East Africa expressed a high enthusiasm for research, driven by a sense of urgency related to the burden from cancer that the region faces. This highlights the need for cancer research training and mentorship in this setting. This work hypothesizes that African principal investigators can operate effectively if proper attention is given to selection and provision of high-quality foundational didactic training to learn the theory and implementation of research as well as to the development of an environment conducive to mentoring.

Challenges and Outcomes of the First Stem Cell Transplant Program in Tanzania, East Africa.

Introduction: Due to the significant resources involved in creating HSCT programs there is a significant disparity in the availability of this treatment modality between the developed and developing countries. This manuscript details the process and the outcomes of the first HSCT program in East Africa which was started at Muhimbili National Hospital (MNH) in Dar-es-Salaam, Tanzania. Materials and Methods: Information and data were collected on the processes which had been implemented for starting the HSCT program at MNH. The details of the collaborations, training, infrastructure development, and acquisition of the biomedical equipment, as well as the actual process for HSCT, as well as the outcomes of treatment are described. Observations. The project has been detailed in 4 stages for ease of description: Stage 1: Preparatory work which was performed by the Government of Tanzania, as well as the administrators and clinicians from MNH (July 2017-September 2021). Stage 2: Exploratory gap analysis by the teams from MNH and International Haematology Consortium of HCG Hospital, India (HCG-IHC) in October 2021. Stage 3: Activities for closure of gaps (November 2021). Stage 4: Stem Cell Transplantation Camps (November 2021 to March 2022). 11 peripheral blood stem cell transplants were done in two camps, November 2021 (5 patients), and February 2022 (6 patients). 10 patients underwent autologous peripheral blood stem cell transplantation for multiple myeloma and 1 for lymphoma. The median duration of hospital stay was 19 ± 6 days. The median time for neutrophil engraftment, it was on 8.8 ± 0.8 days, and for platelet engraftment was 9.6 ± 2.4 days. Progression-free survival was 100%, and there was no mortality. Conclusion: Commonalities in the socioeconomic challenges in developing countries can be leveraged to create robust HSCT programs in other developing countries.

Feasibility and Clinical Acceptability of Automation-Assisted 3D Conformal Radiotherapy Planning for Patients With Cervical Cancer in a Resource-Constrained Setting.

PURPOSE: The Ocean Road Cancer Institute (ORCI) in Tanzania began offering 3D conformal radiation therapy (3DCRT) in 2018. Steep learning curves, high patient volume, and a limited workforce resulted in long radiation therapy (RT) planning workflows. We aimed to establish the feasibility of implementing an automation-assisted cervical cancer 3DCRT planning system. MATERIALS AND METHODS: We performed chart abstractions on 30 patients with cervical cancer treated with 3DCRT at ORCI. The Radiation Planning Assistant (RPA) generated a new automated set of contours and plans on the basis of anonymized computed tomography images. Each were assessed for edit time requirements, dose-volume safety metrics, and clinical acceptability by two ORCI physician investigators. Dice similarity coefficient (DSC) agreement analysis was conducted between original and new contour sets. RESULTS: The average time to manually develop treatment plans was 7 days. Applying RPA, automated same-day contours and plans were developed for 29 of 30 patients (97%). Of the 29 evaluable contours, all were approved with <2 minutes of edit time. Agreement between clinical and RPA contours was highest for the rectum (median DSC, 0.72) and bladder (DSC, 0.90). Agreement was lower with the primary tumor clinical target volume (CTVp; DSC, 0.69) and elective nodal clinical target volume (CTVn; DSC, 0.63). All RPA plans were approved with <4 minutes of edit time. RPA target coverage was excellent, covering the CTVp with median V45 Gy 100% and CTVn with median V45 Gy 99.9%. CONCLUSION: Automation-assisted 3DCRT contouring yielded high levels of agreement for normal structures. The RPA met all planning safety metrics and sustained high levels of clinical acceptability with minimal edit times. This tool offers the potential to significantly decrease RT planning timelines while maintaining high-quality RT delivery in resource-constrained settings.

A mixed methods needs assessment and gap analysis for establishment of a cancer research training program in East Africa.

BACKGROUND: The burden of non-communicable diseases (NCDs), including cancer, in Africa is rising. Policymakers are charged with formulating evidence-based cancer control plans; however, there is a paucity of data on cancers generated from within Africa. As part of efforts to enhance cancer research training in East Africa, we performed a needs assessment and gap analysis of cancer-related research training resources in Tanzania. METHODS: A mixed-methods study to evaluate existing individual, institutional, and national resources supporting cancer research training in Tanzania was conducted. Qualitative data were collected using in-depth interviews while quantitative data were collected using self-administered questionnaires and online surveys. The study also included a desk-review of policy and guidelines related to NCD research and training. Study participants were selected to represent five groups: (i) policymakers; (ii) established researchers; (iii) research support personnel; (iv) faculty members in degree training programs; and (v) post-graduate trainees. RESULTS: Our results identified challenges in four thematic areas. First, there is a need for coordination and monitoring of the cancer research agenda at the national level. Second, both faculty and trainees identified the need for incorporation of rigorous training to improve research competencies. Third, sustained mentoring and institutional investment in development of mentorship resources is critical to empowering early career investigators. Finally, academic institutions can enhance research outputs by providing adequate research infrastructure, prioritizing protected time for research, and recognizing research accomplishments by trainees and faculty. CONCLUSIONS: As we look towards establishment of cancer research training programs in East Africa, investment in the development of rigorous research training, mentorship resources, and research infrastructure will be critical to empowering local health professionals to engage in cancer research activities.

Feasibility Study of a Smartphone Application for Detecting Skin Cancers in People With Albinism.

PURPOSE: Albinism affects some facets of the eye's function and coloration, as well as hair and skin color. The prevalence of albinism is estimated to be one in 2,000-5,000 people in sub-Saharan Africa and one in 270 in Tanzania. People in Tanzania with albinism experience sociocultural and economic disparities. Because of stigma related to albinism, they present to hospitals with advanced disease, including skin cancers. Mobile health (mHealth) can help to bridge some of the gaps in detection and treatment of skin cancers affecting this population. METHODS: We assessed the feasibility of using a mobile application (app) for detection of skin cancers among people with albinism. The study was approved by the Ocean Road Cancer Institute institutional review board. Data, including pictures of the lesions, were collected using a mobile smartphone and submitted to expert reviewers. Expert reviewers' diagnosis options were benign, malignant, or unevaluable. RESULTS: A total of 77 lesions from different body locations of 69 participants were captured by the NgoziYangu mobile app. Sixty-two lesions (81%) were considered malignant via the app and referred for biopsy and histologic diagnosis. Of those referred, 55 lesions (89%) were biopsied, and 47 lesions (85%) were confirmed as skin malignancies, whereas eight (15%) were benign. CONCLUSION: With an increasing Internet coverage in Africa, there is potential for smartphone apps to improve health care delivery channels. It is important that mobile apps like NgoziYangu be explored to reduce diagnostic delay and improve the accuracy of detection of skin cancer, especially in stigmatized groups.

Development of a theory-driven implementation strategy for cancer management guidelines in sub-Saharan Africa.

BACKGROUND: Despite recent international efforts to develop resource-stratified clinical practice guidelines for cancer, there has been little research to evaluate the best strategies for dissemination and implementation in low- and middle-income countries (LMICs). Guideline publication alone is insufficient. Extensive research has shown that structured, multifaceted implementation strategies that target barriers to guideline use are most likely to improve adherence; however, most of this research has been conducted in high-income countries. There is a pressing need to develop and evaluate guideline implementation strategies for cancer management in LMICs in order to address stark disparities in cancer outcomes. METHODS: In preparation for the launch of Tanzania's first National Cancer Treatment Guidelines, we developed a theory-driven implementation strategy for guideline-based practice at Ocean Road Cancer Institute (ORCI). Here, we use the Intervention Mapping framework to provide a detailed stepwise description of our process. First, we conducted a needs assessment to identify barriers and facilitators to guideline-based practice at ORCI. Second, we defined both proximal and performance objectives for our implementation strategy. Third, we used the Capability, Opportunity, Motivation and Behavior/Behavior Change Wheel (COM-B/BCW) framework to categorize the barriers and facilitators, choose behavior change techniques most likely to overcome targeted barriers and leverage facilitators, and select a feasible mode of delivery for each technique. Fourth, we organized these modes of delivery into a phased implementation strategy. Fifth, we operationalized each component of the strategy. Sixth, we identified the indicators of the process, outcome, and impact of our intervention and developed an evaluation plan to measure them using a mixed methods approach. DISCUSSION: We developed a robust, multifaceted guideline implementation strategy derived from a prominent behavior change theory for use in Tanzania. The barriers and strategies we generated are consistent with those well established in the literature, enhancing the validity and generalizability of our process and results. Through our rigorous evaluation plan and systematic account of modifications and adaptations, we will characterize the transferability of "proven" guideline implementation strategies to LMICs. We hope that by describing our process in detail, others may endeavor to replicate it, meeting a widespread need for dedicated efforts to implement cancer guidelines in LMICs.
