RESUMO
BACKGROUND: The demand for healthcare services during the COVID-19 pandemic was excessive for less-resourced settings, with intensive care units (ICUs) taking the heaviest toll. OBJECTIVE: The aim was to achieve adequate personal protective equipment (PPE) use in 90% of patient encounters, to reach 90% compliance with objectives of patient flow (OPF) and to provide emotional support tools to 90% of healthcare workers (HCWs). METHODS: We conducted a quasi-experimental study with an interrupted time-series design in 14 ICUs in Argentina. We randomly selected adult critically ill patients admitted from July 2020 to July 2021 and active HCWs in the same period. We implemented a quality improvement collaborative (QIC) with a baseline phase (BP) and an intervention phase (IP). The QIC included learning sessions, periods of action and improvement cycles (plan-do-study-act) virtually coached by experts via platform web-based activities. The main study outcomes encompassed the following elements: proper utilisation of PPE, compliance with nine specific OPF using daily goal sheets through direct observations and utilisation of a web-based tool for tracking emotional well-being among HCWs. RESULTS: We collected 7341 observations of PPE use (977 in BP and 6364 in IP) with an improvement in adequate use from 58.4% to 71.9% (RR 1.2, 95% CI 1.17 to 1.29, p<0.001). We observed 7428 patient encounters to evaluate compliance with 9 OPF (879 in BP and 6549 in IP) with an improvement in compliance from 53.9% to 67% (RR 1.24, 95% CI 1.17 to 1.32, p<0.001). The results showed that HCWs did not use the support tool for self-mental health evaluation as much as expected. CONCLUSION: A QIC was effective in improving healthcare processes and adequate PPE use, even in the context of a pandemic, indicating the possibility of expanding QIC networks nationwide to improve overall healthcare delivery. The limited reception of emotional support tools requires further analyses.

BACKGROUND: Intravenous drug use, sexual promiscuity and a longer cohabitation period are considered risk factors for familial transmission of hepatitis C virus. The relative importance of this type of transmission is a subject of controversy. AIM: To study familial clustering of hepatitis C virus infection and its risk factors. MATERIAL AND METHODS: HCV positive patients (91 with chronic hepatitis, 88 with cirrhosis, nine with hepatic carcinoma and 29 hemophiliacs) were the index cases. HCV antibodies were measured by ELISA and the type of relationship with the index case was investigated in 317 family members. RESULTS: Positive anti HVC antibodies were detected in 12 of 243 family members of patients with chronic liver disease and in none of the family members of patients with hemophilia. Of these, five were couples of an index case with a long cohabitation period. Ten members had an index case with a severe liver disease (three with Child C cirrhosis and seven with liver carcinoma). CONCLUSIONS: Family transmission of HCV infection is uncommon in Chile. The association of severe liver disease and family transmission could be due to a higher viral load as responsible for transmission during the early periods of a long lasting disease.
