RESUMO
Introduction: Cancer rates are rising in low- and middle-income countries. While point-of-care ultrasound is now available globally and could serve to mitigate against this rise, its use in diagnosing cancers is inconsistent in lower-resourced healthcare contexts. This proof-of-concept study investigates the feasibility of an ultrasound training concept in a low-resource setting. It evaluates whether this educational concept led to improved knowledge and application of ultrasound diagnostics, cancer screening and staging and patient care. Material and methods: The curriculum was developed through expert exchange and is based on the World Health Organisation's Manual of Diagnostic Ultrasound. It consisted of two didactic components: an on-site training phase across 5 days for a total of 24 hours, and a digital follow-up phase involving the meeting of a bi-weekly tumor board online. The learning objectives of the on-site training were normal imaging and recognition of common pathologies of the abdominal organs, vessels, lymph nodes, female breasts and lungs. The virtual tumour boards met to discuss cases and ultrasound findings, thus aiding continuing professional development after the training sessions had concluded. The face-to-face course component was accompanied by tests given before and after training as well as an evaluation sheet (Likert-scale with 1 = 'completely/very good' and 7 'not at all/very poor'). Results: Of 20 participants from a rural hospital in Tanzania, a total of 16 were included in the analysis (clinical officers n = 6; medical officers n = 10). A significant increase in knowledge (p < 0.01) was measured both in the subjective self-assessment and in the theoretical competence tests. In multivariate linear regression, the status 'medical officers yes' (ß = 5.4; p = 0.04) had a significant influence on theory test results at T2. During the 24 virtual tumour board meetings, 28 cases were discussed and a continuous improvement in image acquisition quality was observed. Conclusion: The ultrasound education concept comes with a sustainable increase in clinical competence and improved oncological ultrasound screening locally. There is potential for the transfer of the concept to other locations, which can be explored in the future.
RESUMO
Cancer is becoming a massive public health burden in low- and middle-income countries (LMIC). 70% of all cancer deaths globally are attributed to LMIC while the incidence proportion is below 60%. The main reason for the higher mortality rate is "late-stage presentation" of patients with stage III or IV diseases when being diagnosed. Main reasons for this are limited (financial) resources, poor knowledge of health service provider about cancer, misbelieves and fear among patients as well as low health literacy rate. During the 1st International Conference on Hospital Partnerships, conducted by the German Agency for International Cooperation (GIZ), cancer specialists from seven LMIC and Germany discussed opportunities, challenges and solutions of the development of cancer services. Two days of in-depths discussion identified five topics to be playing a key role in the effort to reduce the cancer burden in LMIC: Health Policy & Financing, Barriers to Access, Capacity Building, Cancer Registries and Adapted Treatment Guidelines. By using mind-mapping technique, stakeholders, core topics, main and important topics were visualized and interconnections displayed. Many topics can be addressed through international cooperations but political willingness and commitment in the respective countries plays the crucial role. An essential contribution will be to assist policy makers in formulating and endorsing affordable and effective health policies. Another lesson learned from this workshop is the similarity of challenges among the participating representatives from different LMIC. The authors of this letter emphasize on the importance of building international long-term cooperations to advance oncology care on a global scale.
