Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hepatitis C virus (HCV) is a leading cause of morbidity and mortality worldwide. This infection continues to represent a major global public health concern. This is why the introduction of potent antivirals for the treatment of HCV has been one of the major breakthroughs of the current medical era.

From a public health perspective, HCV prevalence will be eliminated if the available treatment also targets those most likely to transmit the virus. Despite this scientific advance, a systematic review from the U.S. described that of the 43% of patients aware of their HCV diagnosis, only 16% started treatment. Clearly, the long-known barriers to accessing this treatment must be broken down in order to administer these effective antivirals. The World Health Organization (WHO) has set the ambitious goal of eliminating viral hepatitis as a public health threat by 2030. This goal is really difficult to achieve, especially in low and middle-income countries. Particularly in Argentina, there is a need to improve diagnosis, access to care, and treatment of viral hepatitis. The prospect of viral hepatitis elimination in our country is daunting due to the complexity of the health system and the cost of implementing different strategies. The most pragmatic approach would be to break down national elimination targets into smaller targets for individual populations, for which treatment and prevention interventions can be delivered more quickly and efficiently. This concept is known as micro-elimination. Focusing on micro-elimination of viral hepatitis means working to achieve the WHO target in specific subpopulations. Subpopulations known to have a higher prevalence of HCV infection include prisoners, people who inject drugs, and patients requiring hemodialysis, among others.

Currently, patient unawareness of HCV infection represents one of the major barriers to treatment. In many cases, the diagnosis of HCV was established many years ago and patients do not seek treatment probably because they do not recognize the urgency of treating this asymptomatic infection. It is our goal, then, to identify the group of individuals who have been diagnosed with HCV infection but are not currently undergoing regular visits with health care professionals. This strategy is now called re-linking to the medical care of patients with chronic HCV.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The protocol consists of implementing a strategy to contact patients with HCV who have been lost to follow-up. Establish a single model of confidential information management.

Population. From a cohort of patients, a non-probabilistic sampling of subjects meeting the eligibility criteria will be performed

Study Variables - Demographic data: age, gender

HCV-related data:

* Hepatic complications such as hepatocarcinoma, ascites, encephalopathy, variceal hemorrhage and liver transplantation.
* Extrahepatic manifestations such as non-Hodgkin\'s lymphoma, cryoglobulinemia, porphyria cutanea tarda, cardiovascular disease, diabetes mellitus.
* Previous antiviral treatment with interferon-based or direct antiviral drugs.

Sources of information

* Patient contact: phone call and/or e-mail.
* Review of electronic medical records.

Patient contact strategy:

\- Patients identified as lost to follow-up will be contacted by telephone. Initially 3 calls will be made from Monday to Friday. If the patient is not located, he/she will be called on a Saturday and an e-mail will be sent (if available).

Possible outcomes after the intervention:

* Not contacted despite implemented strategy
* Death
* Treated at another center
* Contacted and candidate for follow-up

Measurement and data logging:

A specific form will be used to record the data, which will later be entered into a computerized database for subsequent analysis of the information. The research physicians who will be blinded will collect the exposure variables included in the survey to the results. Data for each patient will be obtained from the computerized medical record. Those patients with chronic HCV and whose disease course is unknown will be contacted by telephone to evaluate the status of their disease and to offer them, eventually, medical follow-up in our institution.

Ethics and Good Clinical Practices. The study protocol has been developed according to national standards for ethical, legal and juridical requirements, established in the Ministerial Resolution 1480/11 and international standards according to STROBE guidelines and according to ethical criteria of the Helsinki Declaration 2013, Nuremberg Code, Universal Declaration on Human Genome and Human Rights approved by the UNESCO General Conference 1997. As well as according to GCP standards (Good Clinical Practice). The confidentiality of all the data of each individual will be strictly maintained by means of the following strategies: the enrollment of the name, full ID and date of birth will be avoided, and will be replaced by coded data for the identification of the consequent methodologies according to this protocol.

Schedule of activities

* Medical records review phase: 6 months
* Phase of telephone calls: 3 months
* Results evaluation phase 3 months: end of the study and final variable measurements.

Expected results Describing, knowing, understanding the impact of the disease we expect to find a significant number of patients with chronic HCV who are lost to follow-up. Likewise, some of these patients will likely be in follow-up at other institutions.
