Spots Global Cancer Trial Database for Primary Care Transfer for Thyroid Cancer Patients

Study Description

Brief Summary: Introduction: Differentiated thyroid cancer (DTC) is the most common endocrine malignancy. It presents low recurrence rates (2-5%) and the consensus of DTC recommends long-term follow-up, without a definition of maximum follow-up time. The use of Telehealth is a strategy that aims to optimize the transition of care for patients from tertiary care to primary health care, helping to follow up these patients. Objective: To evaluate the impact of the care transition between specialized care and primary health care of patients with DTC using telemedicine solutions. Design / Patients: Randomized clinical trial. Patients with DTC with excellent response (without evidence of disease) after initial treatment. Interventions / Outcomes: Patients will be randomized to follow-up in face-to-face consultations in tertiary care or transfer of care to primary care with support from the Telehealth Center of Rio Grande do Sul. After 18 months, all patients will be evaluated, the primary outcome being DTC recurrence rate. Outcomes related to quality of life and use of the health system will also be evaluated. Both follow-up strategies are expected to be equivalent, making it possible to optimize the use of the health system.

Detailed Description: Differentiated thyroid cancer (DTC) is the most frequent malignant neoplasm of the endocrine system, accounting for approximately 95% of the cases of carcinomas in this system. DTC is considered to be an indolent behavioral neoplasm with low rates of morbidity and mortality (mean survival in 10 years from 93 to 98%), being one of the malignancies with a greater chance of cure. In recent years, the use of the initial treatment response, called "dynamic risk classification", has been advocated in order to better estimate the risk of unfavorable outcomes in patients with DTC. Using this classification, the recurrence rate in the contemporary CDT cohorts has been shown to be very low, at a household of 1-5%. In a cohort of our center, which evaluated 786 patients, the recurrence rate in the group of 357 patients classified as excellent response after the initial treatment was 2.8%, and none of these patients presented structural relapse (median follow-up of 4 years). Thus, it is possible to affirm that most of the patients classified as having an excellent response after initial treatment are permanently free of disease. However, the main consensus on the management of DTC recommends long-term follow-up, not defining the maximum follow-up time. This follow-up consists of consultations in specialized centers (preferably with endocrinologists), laboratory tests (TSH, thyroglobulin and antithyroglobulin antibody) and imaging. In Brazil, the health network is characterized by the heterogeneity of hospital structures regarding the incorporation of technologies and service complexity, with a concentration of financial resources and specialized personnel in large cities and regional imbalance. Within this context, specialized outpatients with high complexity face overcrowding (of patients already under follow-up) and restricted access (to patients in need of follow-up). In this sense, transferring the care of follow-up patients in specialized hospitals to primary care level in their place of origin to maintain follow-up brings benefits to individuals and the system as a whole. The structure of referral of patients to the different levels of care in the Brazilian public health system occurs through the reference and counter-referral system, a fundamental point to guarantee the accessibility, universality, and integrality of care. It is understood as a counter-referral to a primary care level, with a lower degree of complexity, and should be the health unit closest to the patient's home. Facilitating mechanisms of reference and counter-reference processes are fundamental to guarantee the principle of integrality, adequate patient care and rational use of resources. One of the formats for developing health care support and continuing education activities are teleconsulting, which are consultations recorded and performed among workers, health professionals and managers, through telecommunication instruments, with the purpose of clarifying doubts about clinical procedures, health actions and issues related to the work process. It is known that this type of systematic intervention based on practice is one of the most effective ways to promote permanent health education. The use of telehealth, through teleconsulting, for cases referred by primary care physicians to tertiary services is a strategy that aims to qualify and reduce referral lists for other medical professionals. Likewise, the use of telehealth emerges as a counter-referral strategy for patients already served by tertiary care for primary care units, ensuring patient and physician security of adequate management and assisted return for tertiary care, when necessary. In this study, 472 patients with a diagnosis of DTC consecutively attended at the thyroid clinic of the Hospital de Clínicas of Porto Alegre and who presented excellent response to the initial treatment will be invited to participate in the study, and then randomized to two follow-up strategies: 1. Control group: patients will remain in care at the HCPA thyroid disease outpatient clinic; 2. Intervention group: outpatient discharge with telehealth support. Patients with definitive postoperative hypoparathyroidism and/or postoperative vocal cord paralysis requiring tracheostomy will be excluded. All patients will be evaluated by the study team after completing 18 of follow-up. Clinical, laboratory (TSH, thyroglobulin and antithyroglobulin antibody) and imaging (cervical ultrasonography) for DTC relapse will be evaluated in this follow-up visit. The primary endpoint will be the DTC recurrence rate. This will be divided into biochemistry (when there are only signs of disease in laboratory tests) and structural (when demonstrated by clinical or imaging examination). Outcomes related to quality of life and use of the health system will also be evaluated. Both follow-up strategies are expected to be equivalent in relation to DTC recurrences, potentially enabling optimization of the use of the health system.
