Hepatitis C virus micro-elimination in vulnerable populations before and during a global pandemic.

OBJECTIVE: to analyze a hepatitis C virus (HCV) microelimination strategy targeting vulnerable populations and the influence of the pandemic on its maintenance and outcomes. METHODS: in 2018, the Hepatology Unit implemented an HCV microelimination strategy for patients attending drug addiction care centers and Psychiatry Units such as the Alcoholism Treatment Unit. These centers reported suspected or confirmed cases of HCV infection directly to the hepatologists, who, after reviewing the clinical records, cite those patients if necessary. RESULTS: from June 2018 to February 2020, hepatologists were consulted on 37 anti-HCV positive patients, 31 of them were from Drug Addiction Care Centers, 5 from the Alcoholism Disorders Unit and 1 from the Department of Psychiatry. Fibrosis stage: F0-F1, 18 (50%); F2, 9 (25%); F3, 2 (4.2%); F4, 8 (20.8%). Female sex, 6 (16.7%). Required attending: Yes, 27 (73%). 25 (92.6%) went. Outpatient consultation: 10 (27%). Required treatment: 19 (51.3%). Sustained virological response: 19 (100%). Fibrosis stage of treated patients: F0-F1, 13 (68%); F2, 2 (11%); F3, 1 (5%); F4, 3 (16%). Patients from the Psychiatry Department during 2021: 11. 9 (82%) do not need to attend; 2 (18%): their situation is unknown. CONCLUSIONS: sustained communication with centers that care for populations at risk of active HCV infection is needed to detect cases, increase adherence to treatment, and rescue patients who require screening for hepatocarcinoma.

[Validation: reliable instruments needed. Attitude scale and an opinion poll]. / Validación: se necesitan instrumentos fiables.

The use of the scientific method in research and investigation in nursing requires avoiding subjectivity at all times. Professionals obtain data by means of instruments which must be operative, valid and reliable. The authors develop and verify two instruments: a nine question opinion poll which uses tests and retests, having a 93-40% concordance proportion. A Likert type attitude scale, applying the "t" in Student to 59 initial propositions, obtaining a definitive scale having 7 positive items and 7 negative ones which gave a 95% confidence level of statistical meaning for a bilateral test and which had 22 degrees of liberty. This study took place using a pilot group of 43 nurses, it was a practical shop exercise on research in nursing occurred in the Hospital, organized by the Nursing Administration and taught by the group coordinator.
