This measure tells us what percentage of all liver transplants in SF were among people who were HCV seropositive. This measure can be used to estimate the impact of HCV complications on people's livers over the years. A downward trend in this curve is desirable because it tells us that fewer liver diseases are caused by HCV. 

Description of Data: The percent of liver transplants performed on SF residents who were HCV seropositive. 

Time:

• Data time frame: 01/01/2007 - 11/2024
• Based on data as of 11/7/2024

Inclusion/Exclusion Criteria:

• Recipients of liver transplants: only includes people whose ZIP code of permanent residence at time of transplant is a SF ZIP code
  • a list of 51 SF ZIP codes were sent to UNOS
• # of LT related to hepatitis C was identified in one of two ways, HCV-related diagnosis or viral testing. 
• HCV Serostatus Positive is used to include patients with a positive HCV antibody test. 
• HCV NAT (viral testing) was not included. The UNOS research analyst ran the numbers and he found that only a small portion of recipients are tested for HCV NAT. 

Description of Data Source: United Network for Organ Sharing (UNOS) is the private, non-profit organization that manages the nation’s organ transplant system (the Organ Procurement and Transplantation Network (OPTN)) under contract with the federal government.
