Ultrasound as a diagnostic and management tool in hidradenitis suppurativa patients: a multicentre study.

BACKGROUND: It has been reported that clinical evaluation consistently underestimates the severity of hidradenitis suppurativa (HS). OBJECTIVE: To determine the usefulness of ultrasound as a diagnostic tool in HS compared with clinical examination and to assess the subsequent modification of disease management. METHODS: Cross-sectional multicentre study. Severity classification and therapeutic approach according to clinical vs. ultrasound examination were compared. RESULTS: Of 143 HS patients were included. Clinical examination scored 38, 70 and 35 patients as Hurley stage I, II and III, respectively; with ultrasound examination, 21, 80 and 42 patients were staged with Hurley stage I, II and III disease, respectively (P < 0.01). In patients with stage I classification as determined by clinical examination, 44.7% changed to a more severe stage. Clinical examination indicated that 44.1%, 54.5% and 1.4% of patients would maintain, increase or decrease treatment, respectively. For ultrasound examination, these percentages were 31.5%, 67.1% and 1.4% (P < 0.01). Concordance between clinical and ultrasound intra-rater examination was 22.8% (P < 0.01); intra-rater and inter-rater (radiologist) ultrasound agreement was 94.9% and 81.7%, respectively (P < 0.01). LIMITATIONS: The inability to detect lesions that measure ≤0.1 mm or with only epidermal location. CONCLUSION: Ultrasound can modify the clinical staging and therapeutic management in HS by detecting subclinical disease.

Implementation and Operation of an Integrated Quality Management System in Accordance With ISO 9001:2015 in a Dermatology Department. / Implantación y desarrollo de un sistema integrado de gestión de calidad según la norma ISO 9001:2015 en un Servicio de Dermatología.

Quality management systems (QMS) are tools that serve to structure, control and improve the usual activities that take place in an organization or service. The ISO 9001:2015 is an internationally recognized standard, which provides the necessary resources to help an organization to improve its performance, based on the principle of plan-do-control-act, in order to obtain continuous improvement. In the field of health, it is an essential tool for the management of the services offered to patients. The ISO quality certification allows to demonstrate compliance, according to established quality standards. The process of implementing a QMS follows several phases that culminate with the completion of an external audit, which once passed, allows obtaining the quality certification ISO 9001:2015. This article describes the steps to follow to obtain this certification in a Dermatology Service.
