RESUMEN
BACKGROUND: Estimated hepatitis C prevalence within the Veterans Health Administration is higher than the general population and is a risk factor for advanced liver disease and subsequent complications. We describe the hepatitis C care continuum within the Veterans Health Administration 1 January 2014 to 31 December 2022. METHODS: We included individuals in Veterans Health Administration care 2021-2022 who were eligible for direct-acting antiviral treatment 1 January 2014 to 31 December 2022. We evaluated the proportion of Veterans who progressed through each step of the hepatitis C care continuum, and identified factors associated with initiating direct-acting antivirals, achieving sustained virologic response, and repeat hepatitis C viremia. RESULTS: We identified 133 732 Veterans with hepatitis C viremia. Hepatitis C treatment was initiated in 107 134 (80.1%), with sustained virologic response achieved in 98 136 (91.6%). In those who achieved sustained virologic response, 1097 (1.1%) had repeat viremia and 579 (52.8%) were retreated for hepatitis C. Veterans of younger ages were less likely to initiate treatment and achieve sustained virologic response, and more likely to have repeat viremia. Stimulant use and unstable housing were negatively associated with each step of the hepatitis C care continuum. CONCLUSIONS: The Veterans Health Administration has treated 80% of Veterans with hepatitis C in care 2021-2022 and achieved sustained virologic response in more than 90% of those treated. Repeat viremia is rare and is associated with younger age, unstable housing, opioid use, and stimulant use. Ongoing efforts are needed to reach younger Veterans, and Veterans with unstable housing or substance use disorders.

BACKGROUND: The Veterans Affairs (VHA) is working to establish a population-based colorectal cancer screening program for average-risk patients using mailed fecal immunochemical testing (FIT). However, low response rates to mailed FIT may hinder success. Key features of mailed FIT programs, including the use of reminders, differ among various national programs, with limited evidence among veterans. OBJECTIVE: We sought to test whether using reminders, either via telephone call or text message, was effective in improving mailed FIT response rates. DESIGN: We conducted a prospective, randomized quality improvement trial ( ClinicalTrials.gov NCT05012007). Veterans who had not returned a FIT within 2 weeks of receiving the kit were randomized to one of three groups: (1) control (no reminder); (2) an automated telephone call reminder; or (3) an automated text message reminder. PARTICIPANTS: A total of 2658 veterans enrolled at VA Puget Sound Health Care System who were aged 45-75 and had an average risk of colorectal cancer. INTERVENTIONS: A single automated telephone call or text message reminder prompting veterans to return the FIT kit. MAIN MEASURES: Our primary outcome was FIT return at 90 days and our secondary outcome was FIT return at 180 days. KEY RESULTS: Participant average age was 62 years, 88% were men, and 66% White. At 90 days, both the phone and text reminder interventions had higher FIT return rates compared to control (intention-to-treat results (ITT): control 28%, phone 39%, text 38%; p<0.001). At 180 days, FIT kit return remained higher in the reminder interventions (ITT: control 32%, phone 42%, text 40%; p<0.001). CONCLUSIONS: Automated reminders increased colorectal cancer screening completion among average-risk veterans. An automated phone call or text message was equally effective. VHA facilities seeking to implement a mailed FIT program should consider using phone or text reminders, depending on available resources.

BACKGROUND: Reproductive age female individuals comprise the fastest-growing segment of Veterans Health Administration patients, but little is known about rates of reproductive health outcomes among those with chlamydia or gonorrhea infections. Our aim was to estimate the risk of pelvic inflammatory disease, ectopic pregnancy, infertility, and pelvic pain in female veterans tested for chlamydia or gonorrhea. METHODS: We performed a retrospective cohort analysis of female veterans tested for chlamydia or gonorrhea between January 1, 2010, and December 31, 2020. We calculated rates of pelvic inflammatory disease, ectopic pregnancy, infertility, and pelvic pain per 100,000 person-years and used Cox proportional hazards regression models to estimate the risk of these reproductive health conditions according to infection status after adjustment for age, race, ethnicity, military sexual trauma, mental health diagnoses, and substance use disorder. RESULTS: Of female veterans, 232,614 were tested at least once for chlamydia or gonorrhea, with a total of 1,665,786 person-years of follow-up. Of these, 12,971 had positive chlamydia or gonorrhea results (5.8%, 796 cases per 100,000 person-years). Compared with people who tested negative, those testing positive had double the risk of pelvic inflammatory disease (adjusted hazard ratio [aHR], 1.94; 95% confidence interval [CI], 1.81-2.07), 11% increased risk of infertility (aHR, 1.11; 95% CI, 1.04-1.18), 12% increased risk of pelvic pain (aHR, 1.12; 95% CI, 1.08-1.17), and 21% increased risk of any of these conditions (aHR, 1.21; 95% CI, 1.17-1.25). People with positive chlamydia or gonorrhea testing tended to have an increased risk of ectopic pregnancy (aHR, 1.14; 95% CI, 1.0-1.30). Among those with a positive test result, 2218 people (17.1%) had 1 or more additional positive test results. Compared with those with 1 positive test result, people with more than 1 positive test result had a significantly increased risk of pelvic inflammatory disease (aHR, 1.37; 95% CI, 1.18-1.58), infertility (aHR, 1.20; 95% CI, 1.04-1.39), and pelvic pain (aHR1.16; 95% CI, 1.05-1.28), but not ectopic pregnancy (aHR, 1.09; 95% CI, 0.80-1.47). CONCLUSIONS: Female veterans with positive chlamydia or gonorrhea results experience a significantly higher risk of pelvic inflammatory disease, infertility, and pelvic pain, especially among those with repeat infection.

BACKGROUND AND AIMS: The Veterans Health Administration (VHA) provides care for more than 80,000 veterans with cirrhosis. This longitudinal, multimethod evaluation of a cirrhosis care quality improvement program aimed to (1) identify implementation strategies associated with evidence-based, guideline-concordant cirrhosis care over time, and (2) use qualitative interviews to operationalize strategies for a manualized intervention. APPROACH AND RESULTS: VHA providers were surveyed annually about the use of 73 implementation strategies to improve cirrhosis care in fiscal years 2018 (FY18) and 2019 (FY19). Implementation strategies linked to guideline-concordant cirrhosis care were identified using bivariate statistics and comparative configurational methods. Semistructured interviews were conducted with 12 facilities in the highest quartile of cirrhosis care to specify the successful implementation strategies and their mechanisms of change. A total of 106 VHA facilities (82%) responded at least once over the 2-year period (FY18, n = 63; FY19, n = 100). Facilities reported using a median of 12 (interquartile range [IQR] 20) implementation strategies in FY18 and 10 (IQR 19) in FY19. Of the 73 strategies, 35 (48%) were positively correlated with provision of evidence-based cirrhosis care. Configurational analysis identified multiple strategy pathways directly linked to more guideline-concordant cirrhosis care. Across both methods, a subset of eight strategies was determined to be core to cirrhosis care improvement and specified using qualitative interviews. CONCLUSIONS: In a national cirrhosis care improvement initiative, a multimethod approach identified a core subset of successful implementation strategy combinations. This process of empirically identifying and specifying implementation strategies may be applicable to other implementation challenges in hepatology.

BACKGROUND: Mailed fecal immunochemical testing (FIT) programs are increasingly utilized for population-based colorectal cancer (CRC) screening. Advanced notifications (primers) are one behavioral designed feature of many mailed FIT programs, but few have tested this feature among Veterans. OBJECTIVE: To determine if an advanced notification, a primer postcard, increases completion of FIT among Veterans. DESIGN: This is a prospective, randomized quality improvement trial to evaluate a postcard primer prior to a mailed FIT versus mailed FIT alone. PARTICIPANTS: A total of 2404 Veterans enrolled for care at a large VA site that were due for average-risk CRC screening. INTERVENTION: A written postcard sent 2 weeks in advance of a mailed FIT kit that contained information on CRC screening and completing a FIT. MAIN MEASURES: Our primary outcome was FIT completion at 90 days, and our secondary outcome was FIT completion at 180 days. KEY RESULTS: Overall, unadjusted mailed FIT return rates were similar among control vs. primer arms at 90 days (27% vs. 29%, p = 0.11). Our adjusted analysis found a primer postcard did not increase FIT completion compared to mailed FIT alone (OR 1.14 (0.94, 1.37)). CONCLUSIONS: Though primers are often a standard part of mailed FIT programs, we did not find an increase in FIT completion with mailed postcard primers among Veterans. Given the overall low mailed FIT return rates, testing different ways to improve return rates is essential to improving CRC screening.

BACKGROUND: Guideline-adherent hepatitis B virus (HBV) care is critical for patients with HBV, particularly patients with HBV-human immunodeficiency virus (HIV) given increased risks of liver-related complications. However, a comprehensive assessment of HBV-related care in patients with HBV-HIV is lacking. METHODS: We retrospectively assessed adherence to HBV-related care guidelines in all patients with HBV-HIV and HBV monoinfection (HBV-M) in the national Veterans Health Administration healthcare system in 2019. RESULTS: We identified 1021 patients with HBV-HIV among 8323 veterans with chronic HBV. Adherence to HBV guidelines was similar or better in HBV-HIV versus HBV-M, including HBV treatment (97% vs 71%), biannual hepatocellular carcinoma (HCC) surveillance (55% vs 55%) for patients with cirrhosis, hepatitis A virus screening (69% vs 56%), hepatitis C virus screening (100% vs 99%), and on-therapy alanine aminotransferase monitoring (95% vs 96%). Compared with those seeing gastroenterology (GI) or infectious diseases (ID) providers, patients without specialty care were less likely to receive antiviral treatment (none, 39%; GI, 80%; ID, 84%) or HCC surveillance (none, 16%; GI, 66%; ID, 47%). These findings persisted in multivariable analysis. Compared with ID care alone, a higher proportion of patients with HBV-HIV seen dually by GI and ID received HCC surveillance (GIâ +â ID 73% vs ID 31%) and on-therapy HBV-DNA monitoring (GIâ +â ID, 82%; ID, 68%). CONCLUSIONS: Patients with HBV-HIV received similar or higher rates of guideline-adherent HBV-related care than patients with HBV-M. Patients with HBV-HIV under dual GI and ID care achieved higher quality care compared with ID care alone. Specialty care was independently associated with higher quality HBV care in patients with HBV-HIV and HBV-M.

BACKGROUND: Healthcare encounters for the diagnosis and treatment of sexually transmitted infections (STIs) are common and represent an opportunity to discuss and initiate HIV pre-exposure prophylaxis (PrEP). Little is known about how frequently PrEP is discussed and initiated in association with encounters for STIs. DESIGN: Retrospective cohort and nested case-control study, matched by STI date, in national Veterans Health Administration (VHA) facilities from January 2013 to December 2018. PARTICIPANTS: Veterans with a first STI diagnosis (i.e., early syphilis, gonorrhea, or chlamydia) based on ICD codes, excluding those with prior HIV diagnosis, prior PrEP use, or STI diagnosed on screening during a visit to initiate PrEP. MAIN MEASURES: Frequency of PrEP initiation within 90 days of healthcare encounter for STIs. In the case-control study, we performed a structured chart review from the initial STI-related clinical encounter and quantified frequency of PrEP discussions among matched patients who did and did not initiate PrEP in the following 90 days. KEY RESULTS: We identified 23,312 patients with a first STI, of whom 90 (0.4%) started PrEP within 90 days. PrEP initiation was associated with urban residence (OR = 5.0, 95% CI 1.8-13.5), White compared to Black race (OR = 1.7, 95% CI 1.0-2.7), and syphilis diagnosis (OR = 5.7, 95% CI 3.7-8.6). Chart review revealed that discussion of PrEP was rare among people with STIs who did not subsequently start PrEP (1.1%, 95% CI 0.1-4.0). PrEP initiation was associated with documentation of sexual history (80.0% of initiators vs. 51.0% of non-initiators, p < 0.01) and discussion of PrEP (52.2% vs. 1.1%, p < 0.01) during the initial STI diagnosis encounter. CONCLUSIONS: Discussion and initiation of PrEP were rare following healthcare encounters for STIs. Interventions are needed to improve low rates of sexual history-taking and discussion of PrEP during healthcare encounters for STIs.

BACKGROUND: United States (US) rates of sexually transmitted infection (STI) in women, especially gonorrhea and chlamydia, have increased over the past decade. Women Veterans may be at increased risk for STIs due to high rates of sexual trauma. Despite the availability of effective diagnostic tests and evidence-based guidelines for annual screening among sexually active women under age 25, screening rates for gonorrhea and chlamydia remain low in the US and among Veterans. OBJECTIVE: To examine patient characteristics and health system factors associated with gonorrhea and chlamydia testing and case rates among women Veterans in the Veterans Health Administration (VHA) in 2019. DESIGN: We performed a retrospective cohort study of all women Veterans in VHA care between January 1, 2018, and December 31, 2019. PARTICIPANTS: Women Veteran patients were identified as receiving VHA care if they had at least one inpatient admission or outpatient visit in 2019 or the preceding calendar year. KEY RESULTS: Among women under age 25, 21.3% were tested for gonorrhea or chlamydia in 2019. After adjusting for demographic and other health factors, correlates of testing in women under age 25 included Black race (aOR: 2.11, CI: 1.89, 2.36), rural residence (aOR: 0.84, CI: 0.74, 0.95), and cervical cancer screening (aOR: 5.05, CI: 4.59, 5.56). Women under age 25 had the highest infection rates, with an incidence of chlamydia and gonorrhea of 1,950 and 267 cases/100,000, respectively. Incidence of gonorrhea and chlamydia was higher for women with a history of military sexual trauma (MST) (chlamydia case rate: 265, gonorrhea case rate: 97/100,000) and those with mental health diagnoses (chlamydia case rate: 263, gonorrhea case rate: 72/100,000.) CONCLUSIONS: Gonorrhea and chlamydia testing remains underutilized among women in VHA care, and infection rates are high among younger women. Patient-centered, system-level interventions are urgently needed to address low testing rates.

We assessed hepatitis A (HepA) vaccine receipt among susceptible individuals in outbreak and matched nonoutbreak states. Difference-in-differences models and multivariable logistic regression were used to compare HepA vaccination rates in these states. In the postoutbreak year, there was a 112% increase in HepA vaccinations in outbreak states versus a 6% decrease in nonoutbreak states. Differences persisted in our multivariable model (adjusted odds ratio = 2.53; 95% confidence interval = 2.45, 2.61). HepA vaccination rates increased dramatically in outbreak states, but many individuals susceptible to hepatitis A virus remain unvaccinated.

Introduction: The Veteran Integrated Service Network (VISN) 20 Veterans Affairs-Extension for Community Healthcare Outcomes (VA-ECHO) program connects specialty and primary care providers (PCPs) across large geographic areas, utilizing video-teleconferencing with the intention of increasing access to care among underserved and isolated populations. No previously published work describes participation patterns of a multispecialty ECHO program. We describe the development of VISN 20 VA-ECHO program to inform the design and evaluation of ECHO programs. Methods: The participant cohort included VA-affiliated licensed health care professionals, including trainees, who attended at least one VISN 20 VA-ECHO session between April 2012 and December 2018. Participant characteristics reported include gender, clinical location, clinical specialty, discipline, and rurality. Results: Over the 6-year time frame, VISN 20 VA-ECHO offered 945 sessions in 14 clinical specialties and recorded 17,893 hours of attendance. The cohort included 1,346 participants, 74.3% of whom were female, 85.2% employed in medical centers, and 40.7% affiliated with primary care. Most participants (62.3%) attended one specialty exclusively; among all participants, 40% attended five or more sessions. Discussion: Although VA-ECHO was implemented to develop single specialty expertise among PCPs, our participant cohort represented a more diverse audience from a range of disciplines and specialties. Our experience may be valuable to other teams implementing ECHO programs. Conclusions: Through adaptability and strategies that actively promoted inclusion of a diverse audience, VISN 20 VA-ECHO expanded to include multiple clinical specialties and successfully engaged an audience across a large geographic area and beyond PCPs.
RESUMEN
BACKGROUND: Chlamydia trachomatis and Neisseria gonorrhoeae cases reached a record high in the United States in 2018. Although active-duty military service members have high rates of chlamydia and gonorrhea infection, trends in chlamydia and gonorrhea in the Veterans Health Administration (VHA) system have not been previously described, including among patients living with human immunodeficiency virus (HIV) and young women. METHODS: We identified all veterans in VHA care from 2009 through 2019. Tests and cases of chlamydia and gonorrhea were defined based on laboratory results in the electronic health record. Chlamydia and gonorrhea incidence rates were calculated each year by demographic group and HIV status. RESULTS: In 2019, testing for chlamydia and gonorrhea occurred in 2.3% of patients, 22.6% of women aged 18-24 years, and 34.1% of persons living with HIV. The 2019 incidence of chlamydia and gonorrhea was 100.8 and 56.3 cases per 100â 000 VHA users, an increase of 267% and 294%, respectively, since 2009. Veterans aged ≤34 years accounted for 9.5% of the VHA population but 66.9% of chlamydia and 42.9% of gonorrhea cases. Chlamydia and gonorrhea incidence rates in persons living with HIV were 1432 and 1687 per 100â 000, respectively. CONCLUSIONS: The incidence of chlamydia and gonorrhea rose dramatically from 2009 to 2019. Among tested persons, those living with HIV had a 15.2-fold higher unadjusted incidence of chlamydia and 34.9-fold higher unadjusted incidence of gonorrhea compared with those not living with HIV. VHA-wide adherence to chlamydia and gonorrhea testing in high-risk groups merits improvement.

BACKGROUND & AIMS: Patients with chronic hepatitis B (CHB) infection routinely undergo screening for hepatocellular carcinoma (HCC), but the efficacy of screening remains unclear. We aimed to evaluate the impact of screening with ultrasound and/or serum alpha-fetoprotein (AFP) on HCC-related mortality in patients with CHB. METHODS: We performed a matched case-control study of patients with CHB receiving care through the Veterans Affairs (VA) health administration. Cases were patients who died of HCC between 01/01/2004 and 12/31/2017, while controls were patients with CHB who did not die of HCC. Cases were matched to controls by CHB diagnosis date, age, sex, race/ethnicity, cirrhosis, antiviral therapy exposure, hepatitis B e antigen status, and viral load. We identified screening ultrasound and AFPs obtained in the 4 years preceding HCC diagnosis in cases and the equivalent index date in controls. Using conditional logistic regression, we compared cases and controls with respect to receipt of screening. A lower likelihood of screening in cases corresponds to an association between screening and reduced risk of HCC-related mortality. RESULTS: We identified 169 cases, matched to 169 controls. Fewer cases than controls underwent screening with either screening modality (33.7% vs. 58.6%) or both modalities (19.5% vs. 34.4%). In multivariable conditional logistic regression, screening with either modality was associated with a lower risk of HCC-related mortality (adjusted odds ratio [aOR] 0.21, 95% CI 0.09-0.50), as was screening with both modalities (aOR of 0.13; 95% CI 0.04-0.43). CONCLUSIONS: HCC screening was associated with a substantial reduction in HCC-related mortality in VA patients with CHB. LAY SUMMARY: Patients with hepatitis B infection have a high risk of developing liver cancer. It is therefore recommended that they undergo frequent screening for liver cancer, but whether this leads to a lower risk of dying from liver cancer is not clear. In this study, we show that liver cancer screening is associated with a reduction in the mortality from liver cancer in patients with hepatitis B infection.

OBJECTIVE: To describe the incidence and risk factors for mortality and morbidity in patients with cirrhosis undergoing elective or emergent abdominal surgeries. BACKGROUND: Postoperative morbidity and mortality are higher in patients with cirrhosis; variation by surgical procedure type and cirrhosis severity remain unclear. METHODS: We analyzed prospectively-collected data from the Veterans Affairs (VA) Surgical Quality Improvement Program for 8193 patients with cirrhosis, 864 noncirrhotic controls with chronic hepatitis B infection, and 5468 noncirrhotic controls without chronic liver disease, who underwent abdominal surgery from 2001 to 2017. Data were analyzed using random-effects models controlling for potential confounders. RESULTS: Patients with cirrhosis had significantly higher 30-day mortality than noncirrhotic patients with chronic hepatitis B [4.4% vs 1.3%, adjusted odds ratio (aOR) 2.80, 95% confidence interval (CI) 1.57-4.98] or with no chronic liver disease (0.8%, aOR 4.68, 95% CI 3.27-6.69); mortality difference was highest in patients with Model for End-stage Liver Disease (MELD) score ≥10. Among patients with cirrhosis, postoperative mortality was almost 6 times higher after emergent rather than elective surgery (17.2% vs. 2.1%, aOR 5.82, 95% CI 4.66-7.27). For elective surgeries, 30-day mortality was highest after colorectal resection (7.0%) and lowest after inguinal hernia repair (0.6%). Predictors of postoperative mortality included cirrhosis-related characteristics (high MELD score, low serum albumin, ascites, encephalopathy), surgery-related characteristics (emergent vs elective, type of surgery, intraoperative blood transfusion), comorbidities (chronic obstructive pulmonary disease, cancer, sepsis, ventilator dependence, functional status), and age. CONCLUSIONS: Accurate preoperative risk assessments in patients with cirrhosis should account for cirrhosis severity, comorbidities, type of procedure, and whether the procedure is emergent versus elective.

BACKGROUND: Patients with hepatitis C virus (HCV) frequently remain at risk for cirrhosis after sustained virologic response (SVR). Existing cirrhosis predictive models for HCV do not account for dynamic antiviral treatment status and are limited by fixed laboratory covariates and short follow up time. Advanced fibrosis assessment modalities, such as transient elastography, remain inaccessible in many settings. Improved cirrhosis predictive models are needed. METHODS: We developed a laboratory-based model to predict progression of liver disease after SVR. This prediction model used a time-varying covariates Cox model adapted to utilize longitudinal laboratory data and to account for antiretroviral treatment. Individuals were included if they had a history of detectable HCV RNA and at least 2 AST-to-platelet ratio index (APRI) scores available in the national Veterans Health Administration from 2000 to 2015, Observation time extended through January 2019. We excluded individuals with preexisting cirrhosis. Covariates included baseline patient characteristics and 16 time-varying laboratory predictors. SVR, defined as permanently undetectable HCV RNA after antiviral treatment, was modeled as a step function of time. Cirrhosis development was defined as two consecutive APRI scores > 2. We predicted cirrhosis development at 1-, 3-, and 5-years follow-up. RESULTS: In a national sample of HCV patients (n = 182,772) with a mean follow-up of 6.32 years, 42% (n = 76,854) achieved SVR before 2016 and 16.2% (n = 29,566) subsequently developed cirrhosis. The model demonstrated good discrimination for predicting cirrhosis across all combinations of laboratory data windows and cirrhosis prediction intervals. AUROCs ranged from 0.781 to 0.815, with moderate sensitivity 0.703-0.749 and specificity 0.723-0.767. CONCLUSION: A novel adaptation of time-varying covariates Cox modeling technique using longitudinal laboratory values and dynamic antiviral treatment status accurately predicts cirrhosis development at 1-, 3-, and 5-years among patients with HCV, with and without SVR. It improves upon earlier cirrhosis predictive models and has many potential population-based applications, especially in settings without transient elastography available.

BACKGROUND & AIMS: It is unclear if hepatocellular carcinoma (HCC) risk declines over time after hepatitis C virus (HCV) eradication. We analyzed changes in HCC annual incidence over time following HCV eradication and identified dynamic markers of HCC risk. METHODS: We identified 48,135 patients who initiated HCV antiviral treatment from 2000 through 2015 and achieved a sustained virologic response (SVR) in the Veterans Health Administration (29,033 treated with direct-acting antiviral [DAA] agents and 19,102 treated with interferon-based regimens). Patients were followed after treatment until February 14, 2019 (average 5.4 years), during which 1509 incident HCCs were identified. RESULTS: Among patients with cirrhosis before treatment with DAAs (n = 9784), those with pre-SVR fibrosis-4 (FIB-4) scores ≥3.25 had a higher annual incidence of HCC (3.66%/year) than those with FIB-4 scores <3.25 (1.16%/year) (adjusted hazard ratio 2.14; 95% confidence interval 1.66-2.75). In DAA-treated patients with cirrhosis and FIB-4 scores ≥3.25, annual HCC risk decreased from 3.8%/year in the first year after SVR to 2.4%/year by the fourth year (P=.01). In interferon-treated patients with FIB-4 scores ≥3.25, annual HCC risk remained above 2%/year, even 10 years after SVR. A decrease in FIB-4 scores from ≥3.25 pre-SVR to <3.25 post-SVR was associated with an approximately 50% lower risk of HCC, but the absolute annual risk remained above 2%/year. Patients without cirrhosis before treatment (n = 38,351) had a low risk of HCC, except for those with pre-SVR FIB-4 scores ≥3.25 (HCC risk 1.22%/year) and post-SVR FIB-4 scores ≥3.25 (HCC risk 2.39%/year); risk remained high for many years after SVR. CONCLUSIONS: Patients with cirrhosis before an SVR to treatment for HCV infection continue to have a high risk for HCC (>2%/year) for many years, even if their FIB-4 score decreases, and should continue surveillance. Patients without cirrhosis but with FIB-4 scores ≥3.25 have a high enough risk to merit HCC surveillance, especially if FIB-4 remains ≥3.25 post-SVR.

BACKGROUND & AIMS: Military veterans have been reported to have higher odds of hepatitis B virus (HBV) exposure after adjustment for demographic factors, family income, and birthplace. It is not clear whether military-related exposures are associated with risk of HBV exposure in veterans. METHODS: A random sample of veterans receiving care from 1998 through 2000 in the national Veterans' Health Administration system completed a risk factor survey and underwent phlebotomy analysis (N = 1146). Stored serum samples were reanalyzed to determine prevalence of HBV exposure (core antibody positive), infection (surface antigen or DNA positive), and immunity (surface antibody positive, surface antigen negative, and core antibody negative). Associations between military-related risk factors and HBV exposure were assessed using logistic regression. RESULTS: The prevalence values for infection, exposure, and immunity were 0.7% (95% CI, 0.3-1.5), 13.6% (95% CI, 11.5-16.1), and 6.2% (95% CI, 4.7-8.2), respectively. Evidence of HBV exposure was highest among respondents with traditional risk factors (such as drug use or high-risk sexual practices). More than half the individuals with HBV exposure (53%) reported no history of traditional risk factors; of these, 59.5% reported a history of combat exposure. After adjustment for demographic and traditional risk factors, service in a combat zone (adjusted odds ratio, 1.56; 95% CI, 1.01-2.41) and being wounded in combat (adjusted odds ratio, 1.79; 95% CI, 1.04-3.08) were associated independently with exposure to HBV. CONCLUSIONS: In an analysis of US military veterans, we found the prevalence of exposure to HBV to be highest among veterans with traditional risk factors but also independently related to military combat or being wounded in combat. Studies are needed to determine whether veterans with combat exposure before the era of universal vaccination should be screened for HBV exposure.

Decompensated cirrhosis is associated with high morbidity and mortality. However, no standardized quality measures (QMs) have yet been adopted widely. The Veterans Affairs (VA) Advanced Liver Disease Technical Advisory Group recently developed a set of six internal QMs to guide quality improvement efforts in cirrhosis in the domains of access to care, hepatocellular carcinoma surveillance, variceal surveillance, quality of inpatient care for upper gastrointestinal bleeding, and cirrhosis-related rehospitalizations. We aimed to (1) quantify adherence to cirrhosis QMs and (2) determine whether adherence was associated with all-cause mortality and health care use within a large national cohort of veterans with cirrhosis. We performed a retrospective study using data from the Veterans Outcomes and Costs Asociated with Liver Disease cohort of 121,129 patients newly diagnosed with cirrhosis from January 1, 2008, to December 31, 2016, at 128 VA facilities. The mean follow-up time was 2.7 years (interquartile range, 1.1-5.1 years). Adherence to outpatient access to specialty care was 71%, variceal surveillance was 32%, and early postdischarge care was 54%. In adjusted analyses, outpatient access to specialty care (hazard ratio [HR], 0.80; 95% confidence interval [CI], 0.78-0.82), hepatocellular carcinoma surveillance (HR, 0.92; 95% CI, 0.90-0.95), variceal surveillance (HR, 0.93; 95% CI, 0.89-0.99), and early postdischarge care (HR, 0.57; 95% CI, 0.54-0.60) were associated with lower all-cause mortality. Readmissions after 30 days (HR, 1.53; 1.46-1.60) and 90 days (HR, 1.88; 95% CI, 1.54-1.70) were associated with higher all-cause mortality. Higher adherence to QMs was also associated with lower inpatient health care use. Conclusion: Five of the six proposed VA cirrhosis QMs were measurable using existing data sources, associated with mortality and health care use, and may be used to guide future quality improvement efforts in cirrhosis.

BACKGROUND: In response to the development of highly effective but expensive new medications, policymakers, payors, and health systems are considering novel and pragmatic ways to provide these medications to patients. One approach is to target these treatments to those most likely to benefit. However, to maximize the fairness of these policies, and the acceptance of their implementation, the values and beliefs of patients should be considered. The provision of treatments for chronic hepatitis C (CHC) in the resource-constrained context of the Veterans Health Administration (VHA) offered a real-world example of this situation, providing the opportunity to test the value of using Democratic Deliberation (DD) methods to solicit the informed opinions of laypeople on this complex issue. METHODS: We recruited Veterans (n = 30) from the VHA to attend a DD session. Following educational presentations from content experts, participants engaged in facilitated small group discussions to: 1) identify strategies to overcome CHC treatment barriers and 2) evaluate, vote on, and modify/improve two CHC treatment policies - "first come, first served" (FCFS) and "sickest first" (SF). We used transcripts and facilitators' notes to identify key themes from the small group discussions. Additionally, participants completed pre- and post-DD surveys. RESULTS: Most participants endorsed the SF policy over the FCFS policy, emphasizing the ethical and medical appropriateness of treating the sickest first. Concerns about SF centered on the difficulty of implementation (e.g., how is "sickest" determined?) and unfairness to other Veterans. Proposed modifications focused on: 1) the need to consider additional health factors, 2) taking behavior and lifestyle into account, 3) offering education and support, 4) improving access, and 5) facilitating better decision-making. CONCLUSIONS: DD offered a robust and useful method for addressing the allocation of the scarce resource of CHC treatment. Participants were able to develop a modified version of the SF policy and offered diverse recommendations to promote fairness and improve quality of care for Veterans. DD is an effective approach for incorporating patient preferences and gaining valuable insights for critical healthcare policy decisions in resource-limited environments.

BACKGROUND & AIMS: Screening patients with cirrhosis for hepatocellular carcinoma (HCC) has been recommended. We conducted a matched case-control study within the US Veterans Affairs (VA) health care system to determine whether screening by abdominal ultrasonography (USS) and/or by measuring serum level of α-fetoprotein (AFP) was associated with decreased cancer-related mortality in patients with cirrhosis. METHODS: We defined cases (n = 238) as patients with cirrhosis who died of HCC from January 1, 2013 through August 31, 2015 and had been in VA care with a diagnosis of cirrhosis for at least 4 years before the diagnosis of HCC. We matched each case to 1 control (n = 238), defined as a patient with cirrhosis who did not die of HCC and had been in VA care for at least 4 years before the date of the matched case's HCC diagnosis. Controls were matched to cases by year of cirrhosis diagnosis, race and ethnicity, age, sex, etiology of cirrhosis, Model for End-Stage Liver Disease score, and VA medical center. We identified all USS and serum AFP tests performed within 4 years before the date of HCC diagnosis in cases or the equivalent index date in controls and determined by chart extraction (blinded to case or control status) whether these tests were performed for screening. RESULTS: There were no significant differences between cases and controls in the proportions of patients who underwent screening USS (52.9% vs 54.2%), screening measurement of serum AFP (74.8% vs 73.5%), screening USS or measurement of serum AFP (81.1% vs 79.4%), or screening USS and measurement of serum AFP (46.6% vs 48.3%) within 4 years before the index date, with or without adjusting for potential confounders. There also was no difference in receipt of these screening tests within 1, 2, or 3 years before the index date. CONCLUSIONS: In a matched case-control study of the VA health care system, we found that screening patients with cirrhosis for HCC by USS, measurement of serum AFP, either test, or both tests was not associated with decreased HCC-related mortality. We encourage additional case-control studies to evaluate the efficacy of screening for HCC in other health care systems, in which available records are sufficiently detailed to enable identification of the indication for USS and AFP tests.

BACKGROUND & AIMS: Despite increased risks for adverse effects in patients with cirrhosis, little is known about opioid prescriptions for this population. We aimed to assess time trends in opioid prescribing and factors associated with receiving opioids among patients with cirrhosis. METHODS: Among Veterans with cirrhosis, identified using national Veterans Health Administration data (2005-2014), we assessed characteristics of patients and their prescriptions for opioids. We calculated the annual proportion of patients receiving any opioid prescription. Among opioid recipients, we assessed prescriptions that were long-term (>90 days' supply), for high doses (>100 MME/day), or involved combinations of opioids and acetaminophen or benzodiazepine. We evaluated patient characteristics independently associated with long-term and any opioid prescriptions using mixed-effects regression models. RESULTS: Among 127,239 Veterans with cirrhosis, 97,974 (77.0%) received a prescription for an opioid. Annual opioid prescriptions increased from 36% in 2005 to 47% in 2014 (P < .01). Among recipients of opioids, the proportions of those receiving long-term prescriptions increased from 47% in 2005 to 54% in 2014 (P < .01), and19%-21% received prescriptions for high-dose opioids. Prescriptions for combinations of opioids and acetaminophen decreased from 68% in 2005 to 50% in 2014 (P < .01) and for combinations of opioids and benzodiazepines decreased from 24% to 19% over this time (P < .01). Greater probability of long-term opioid prescriptions was independently associated with younger age, female sex, white race, hepatitis C, prior hepatic decompensation, hepatocellular carcinoma, mental health disorders, nicotine use disorders, medical comorbidities, surgery, and pain-related conditions. CONCLUSION: Among Veterans with cirrhosis, 36%-47% were prescribed opioids in each year. Mental health disorders and hepatic decompensation were independently associated with long-term opioid prescriptions.
