RESUMO
Global cervical cancer incidence and mortality have remained a major public health problem. Depending on the quality and coverage of preventive programs, and the capacity of health care systems, different screening tests are used, with the Pap smear being the most widely implemented. Several difficulties have been reported in accessing timely detection, causing late cervical cancer diagnosis. Trying to close these gaps, new screening devices have been developed in recent years; however, there is a lack of knowledge about whether or not women perspective has been included in the design process and technological development of these devices. This scoping review aimed to describe and synthesize scientific literature on women's critical experiences with Pap smears to prospectively contribute to the design, development, and scale-up of cervical cancer screening devices. The electronic databases Web of Science, Scopus, PubMed, PsycINFO and SciELO were searched for relevant studies published between 2012 and 2021; finally, 18 qualitative studies were included. Experiences were classified into four categories: fear and embarrassment, speculum pain and discomfort, outcome distress and health service barriers. Critical experiences before, during, and after the test were analyzed in turn. In particular, during the test, women reported pain associated with the use of the speculum. The acceptability of new screening devices will largely depend on comfort during the test and timely delivery of results. This review provides a useful qualitative synthesis, not only to advance the design of novel devices but also for future implementation research in cervical screening services.
RESUMO
This article presents the design process of innovative prototypes for cervical cancer prevention in primary care centers located in low-income settings in Cali, Colombia, using the Human-Centered Design (HCD). The project was developed in collaboration with a public healthcare network comprised of 38 urban and rural centers with women between the ages of 25 and 65 years, healthcare providers of the cancer program, healthcare administrators and the general manager of said network. Our HCD process involved five stages: research, need synthesis, ideation and co-design process, prototyping and in-context usability testing. In practice, some of the stages are overlapped and iterated throughout the design process. We conducted observations, open-ended interviews and conversations, multi-stakeholder workshops, focus groups, systematic text condensation analyses and tests in real contexts. As a result, we designed four prototypes: (1) 'Encanto': An educational manicure service, (2) 'No le des la espalda a la citología': A media-based strategy, (3) An educational wireless queuing device in the waiting room, and (4) Citobot: A cervical cancer early detection device, system, and method. The tests carried out with each prototype showed their value, limitations and possibilities in terms of subsequent development and validation through public health research or clinical research. We recognize that a longer-term evaluation is required in order to determine whether the prototypes will be used regularly, integrated into cervical cancer screening services and effectively improve access to cytology as a screening test. We conclude that HCD is a useful for design-based prevention in the field of cervical cancer. The integration of this approach with public health research would allow the generation of evidence during to the formulation of policies and programs as well as optimize existing interventions and, ultimately, facilitate the scalability and financing of what actually works.
