RESUMO
Background: Several studies have justified use of chest computed tomography (CT) in diagnosis, evaluation of severity, treatment response, and complications of coronavirus disease 2019 (COVID-19) pneumonia. Increased utilization of CT in patients with known or suspected COVID-19 pneumonia has resulted in concerns of overuse, lack of protocol optimization, and radiation exposure. Aims: The study was conducted to develop and implement optimized protocol for chest CT for reducing radiation dose in adult patients suspected or diagnosed to have COVID-19 infection. Setting and Design: The study was conducted in the department of radiology of a rural tertiary care teaching hospital in western India. Clinical audit was used as a tool to impart and assess the impact of optimized chest CT protocol. Methods and Material: The pre-intervention audit included radiation dosimetry data, number of phases and length of scan of 50 adult patients, undergoing non-contrast chest CT scans in March 2021. A brief educational intervention outlining the parameters of optimized protocol was conducted on April 1, 2021.The post-intervention audit consisted of two cycles for 109 and 67 chest CT scans in the months April and May 2021. Results: The optimized protocol was found clinically adequate with a good inter-rater reliability. The compliance to the optimized protocol was weak in audit cycle 2, which improved significantly in audit cycle 3 after reinforcement. The mean (SD) per scan Computed Tomography Dose Index-Volume (CTDI-vol) reduced significantly across audit cycles [22.06 (12. 31) Vs. 10.58 (7.58) Vs. 4.51 (2.90) milli Gray, respectively, P < 0.001]. Similar findings were noted for Dose Length Product (DLP). Conclusion: Clinical audit of chest CT protocol and resultant radiation doses provided adequate feedback for dose optimization. A simple educational intervention helped achieve dose optimization.
RESUMO
BACKGROUND: The prevalence and pattern of skin diseases are influenced by the overall ecosystem of the region. There is a dearth of research about prevalence, health-care seeking, compliance, and treatment outcome in skin diseases among scheduled tribes. OBJECTIVES: The aim of this study is to understand the magnitude of skin diseases in tribal area of Dahod, Gujarat using a simple "Store and Forward" technique of teledermatology. MATERIALS AND METHODS: A cross-sectional study was conducted in 10 randomly selected villages of Dahod and Jhalod blocks of Dahod district of Gujarat during June-August 2017. Trained surveyors visited households randomly in different localities (called Faliya) of each village ensuring representativeness. Survey responses were captured on mobile-based MAGPI portal, and images of skin conditions were capture on smart phones, and de-identified images were transferred over WhatsApp. RESULTS: A total of 781 households were approached in 10 villages and 2214 participants consented. Among them, 549 were identified with suspected skin diseases, but 520 consented for photograph. The skin diseases were more prevalent among males, children, and elderly. Of 520, 44 (8.5%) could not be assess due to poor quality photograph and 35 (6.7%) did not have any clinically significant condition. Thus, of 2214 participants, 441 (20%) had skin diseases, and infections and eczema were major conditions constituting two-third of the skin diseases in the study population. The treatment-seeking behavior and compliance to treatment was poor. CONCLUSION: Considering the high prevalence of skin diseases in tribal villages of Dahod, Gujarat coupled with limited availability of trained dermatologist, new innovative avenues like teledermatology should be explored.
