Its complexity and impact on patients highlight the need for multidisciplinary care that can address the physical, psychological, and social aspects. Centers of excellence can ideally provide the necessary infrastructure, resources, and expertise to effectively treat HS. However, there are still no consolidated models of centers of excellence in HS, and establishing their foundations is an intricate research challenge. Purposely, design and co-creation as innovation techniques are helpful approaches to this type of research.Methods: In this study, we conducted a co-creation with consensus among HS specialists to propose the criteria and requirements to establish outpatient centers of excellence of HS in Brazil. We followed a linear process with mixed methods in 6 stages.Results: The process resulted in 10 categories for establishing outpatient centers, including their respective requirements, rationale, and classification. The categories include onboarding and welcoming; infrastructure and procedures; infusion therapy; flows and referrals; staffing; disease management; metrics during diagnosis; metrics during treatment; awareness and advocacy; research and education.Discussion: The idealized outpatient centers can play a role in the complete multidisciplinary treatment for HS and advancing the science of healthcare services by providing a focus for research, training, and translation of findings into practice.Keywords: hidradenitis suppurativa, centers of excellence, co-design, consensus, health services research, patient-centered care, community-based participatory research, healthcare innovation

Objectives: The scant data about non-cystic fibrosis bronchiectasis, including tuberculosis sequelae and impairment of lung function, can bias the preoperative physiological assessment. Our goal was to evaluate the changes in lung function and exercise capacity following pulmonary resection in these patients; we also looked for outcome predictors., Methods: We performed a non-randomized prospective study evaluating lung function changes in patients with non-cystic fibrosis bronchiectasis treated with pulmonary resection. Patients performed lung function tests and cardiopulmonary exercise tests preoperatively and 3 and 9 months after the operation. Demographic data, comorbidities, surgical data and complications were collected., Results: Forty-four patients were evaluated for lung function. After resection, the patients had slightly lower values for spirometry: forced expiratory volume in 1 s preoperatively: 2.21 l ± 0.8; at 3 months: 1.9 l ± 0.8 and at 9 months: 2.0 l ± 0.8, but the relationship between the forced expiratory volume in 1 s and the forced vital capacity remained. The gas diffusion measured by diffusing capacity for carbon monoxide did not change: preoperative value: 23.2 ml/min/mmHg ± 7.4; at 3 months: 21.5 ml/min/mmHg ± 5.6; and at 9 months: 21.7 ml/min/mmHg ± 8.2. The performance of general exercise did not change; peak oxygen consumption preoperatively was 20.9 ml/kg/min ± 7.4; at 3 months: 19.3 ml/kg/min ± 6.4; and at 9 months: 20.2 ml/kg/min ± 8.0. Forty-six patients were included for analysis of complications. We had 13 complications with 2 deaths. To test the capacity of the predicted postoperative (PPO) values to forecast complications, we performed several multivariate and univariate analyses; none of them was a significant predictor of complications. When we analysed other variables, only bronchoalveolar lavage with positive culture was significant for postoperative complications (P = 0.0023). Patients who had a pneumonectomy had a longer stay in the intensive care unit (P = 0.0348)., Conclusions: The calculated PPO forced expiratory volume in 1 s had an excellent correlation with the measurements at 3 and 9 months; but the calculated PPO capacity for carbon monoxide and the PPO peak oxygen consumption slightly underestimated the 3- and 9-month values. However, none of them was a predictor for complications. Better tools to predict postoperative complications for patients with bronchiectasis who are candidates for lung resection are needed., Clinical Trial Registration Number: Clinicaltrials.gov: NCT01268475., (© The Author(s) 2021.

Background: Bronchiectasis is a significant cause of morbidity. Surgical resection is a treatment option, but its main outcomes regarding quality of life (QOL) and physiologic consequences have not been addressed previously, to our knowledge. We aimed to evaluate the effect of surgical procedures on QOL, exercise capacity, and lung function in patients with bronchiectasis in whom medical treatment was unsuccessful., Methods: Patients with noncystic fibrosis in whom medical treatment was unsuccessful and who were candidates for lung resection were enrolled in a prospective study. The main measurements before lung resection and 9 months afterward were QOL according to the Short Form 36 Health Survey and World Health Organization Quality of Life Questionnaires, lung function test results, and the results of maximal cardiopulmonary exercise testing on a cycle ergometer., Results: Of 61 patients who were evaluated, 53 (50.9% male, age 41.3 ± 12.9 years) underwent surgical resection (83% lobectomies), and 44 completed the 9-month follow-up. At baseline, they had low QOL scores, mild obstruction, and diminished exercise capacity. After resection, 2 patients died and adverse events occurred in 24.5%. QOL scores improved remarkably at the 9-month measurements, achieving values considered normal for the general population in most dimensions. Functionally, resection caused mild reduction of lung volume; nevertheless, exercise capacity was not decreased. In fact, 52% of the patients improved their exercise performance. Multiple linear regression analysis showed that low QOL before resection was an important predictor of QOL improvement after resection (p = 0.0001)., Conclusions: Lung resection promotes a significant improvement in the QOL of patients with noncystic fibrosis bronchiectasis without compromising their exercise capacity., (Copyright © 2014 The Society of Thoracic Surgeons.
