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. [ABSTRACT FROM AUTHOR]

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.

Background: We aimed to investigate the association of hepatic steatosis with liver fibrosis and to assess the interactive effects of hepatic steatosis and insulin resistance on liver fibrosis in a nationally representative sample of United States adults. Methods: We conducted a cross-sectional analysis using data from National Health and Nutrition Examination Survey 2017 to 2018, which for the first time included transient elastography to assess liver stiffness and hepatic steatosis. We evaluated the association between hepatic steatosis (using controlled attenuation parameter [CAP]) and clinically significant liver fibrosis (defined as liver stiffness ≥7.5 kPa) using logistic regression with an interaction term for hepatic steatosis and insulin resistance (defined as homeostatic model assessment of insulin resistance ≥3.0). Results: Among adults undergoing transient elastography (n=2,023), 45.9% had moderate or greater hepatic steatosis and 11.3% had clinically significant liver fibrosis. After adjustment for demographic and metabolic factors, the odds of significant liver fibrosis increased as CAP score rose (odds ratio, 1.35 per standard deviation increment; 95% confidence interval, 1.11 to 1.64). We detected a significant interaction effect between CAP score and insulin resistance on the probability of significant liver fibrosis (P=0.016 for interaction). The probability of significant liver fibrosis increased in the presence of insulin resistance with increasing CAP score, while those without insulin resistance had low probability of significant liver fibrosis, even with high CAP scores. Conclusion: Individuals with hepatic steatosis had higher odds of fibrosis when insulin resistance was present. Our findings emphasize the importance of the metabolic aspects of the disease on fibrosis risk and suggest a need to better identify patients with metabolic associated fatty liver disease.

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 100 000 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 100 000, 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. [ABSTRACT FROM AUTHOR]

Background: Approximately 233,898 individuals in the Veterans Affairs healthcare network are hepatitis C virus (HCV)-infected, making the Veterans Affairs the single largest provider of HCV care in the USA. Direct-acting antiviral treatment regimens for HCV offer high cure rates. However, these medications pose an enormous financial burden, and whether HCV cure is associated with decreased healthcare costs is poorly defined.Aims: To measure downstream healthcare costs in a national population of HCV-infected patients up to 9 years post-HCV antiviral treatment, to compare downstream healthcare costs between cured and uncured patients, and to assess impact of cirrhosis status on cost differences.Methods: This is a retrospective cohort study (2004-2014) of hepatitis C-infected patients who initiated antiviral treatment within the United States Veterans Affairs healthcare system October 2004-September 2013. We measured inpatient, outpatient, and pharmacy costs after HCV treatment.Results: For the entire cohort, cure was associated with mean cumulative cost savings in post-treatment years three-six, but no cost savings by post-treatment year nine. By post-treatment year nine, cure in cirrhosis patients was associated with a mean cumulative cost savings of $9474 (- 32,666 to 51,614) per patient, while cure in non-cirrhotic patients was associated with a mean cumulative cost excess of $2526 (- 12,211 to 7159) per patient.Conclusions: Among patients with cirrhosis at baseline, cure is associated with absolute cost savings up to 9 years post-treatment compared to those without cure. Among patients without cirrhosis, early post-treatment cost savings are counterbalanced by higher costs in later years. [ABSTRACT FROM AUTHOR]

Rationale: Primary care providers (PCPs) frequently encounter sleep complaints, especially in regions with limited specialty care access.Objectives: The U.S. Department of Veterans Affairs Extension for Community Healthcare Outcomes (VA-ECHO) program (based on Project ECHO) has successfully provided rural PCP education in subspecialty areas, including hepatitis C. We describe the feasibility of an ECHO program for sleep medicine.Methods: ECHO creates a virtual learning community through video-teleconferencing, combining didactics with individualized clinical case review. We invited multidisciplinary providers to attend up to 10 stand-alone, 1-hour sessions. Invitees completed a needs assessment, which guided curriculum development. After program completion, we examined participant characteristics and self-reported changes in practice and comfort with managing sleep complaints. We surveyed participation barriers among invitees with low/no attendance.Measurements and Main Results: Of the 39 program participants, 38% worked in rural healthcare. Participants included nurse practitioners (26%), registered nurses (21%), and physicians (15%). Seventeen (44%) completed the summative program evaluation. Respondents anticipated practice change from the program, especially in patient education about sleep disorders (93% of respondents). Respondents reported improved comfort managing sleep complaints, especially sleep-disordered breathing, insomnia, and sleep in post-traumatic stress disorder (80% of respondents each). A follow-up survey of program invitees who attended zero to two sessions reported scheduling conflicts (62%) and lack of protected time (52%) as major participation barriers.Conclusions: Participants in a pilot sleep medicine VA-ECHO program report practice change and increased comfort managing common sleep complaints. Future work is needed to identify objective measures of return on investment and address participation barriers. [ABSTRACT FROM AUTHOR]

Background: Patients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed.Objective: To evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire-up to a year before surgery-were associated with the risk of postoperative complications.Design: This is a cohort study.Setting and Participants: Male Veterans Affairs (VA) patients were eligible if they had major noncardiac surgery assessed by the VA's Surgical Quality Improvement Program (VASQIP) in fiscal years 2004-2006, and completed the AUDIT-C alcohol screening questionnaire (0-12 points) on a mailed survey within 1 year before surgery.Main Outcome Measure: One or more postoperative complication(s) within 30 days of surgery based on VASQIP nurse medical record reviews.Results: Among 9,176 eligible men, 16.3% screened positive for alcohol misuse with AUDIT-C scores ≥ 5, and 7.8% had postoperative complications. Patients with AUDIT-C scores ≥ 5 were at significantly increased risk for postoperative complications, compared to patients who drank less. In analyses adjusted for age, smoking, and days from screening to surgery, the estimated prevalence of postoperative complications increased from 5.6% (95% CI 4.8-6.6%) in patients with AUDIT-C scores 1-4, to 7.9% (6.3-9.7%) in patients with AUDIT-Cs 5-8, 9.7% (6.6-14.1%) in patients with AUDIT-Cs 9-10 and 14.0% (8.9-21.3%) in patients with AUDIT-Cs 11-12. In fully-adjusted analyses that included preoperative covariates potentially in the causal pathway between alcohol misuse and complications, the estimated prevalence of postoperative complications increased significantly from 4.8% (4.1-5.7%) in patients with AUDIT-C scores 1-4, to 6.9% (5.5-8.7%) in patients with AUDIT-Cs 5-8 and 7.5% (5.0-11.3%) among those with AUDIT-Cs 9-10.Conclusions: AUDIT-C scores of 5 or more up to a year before surgery were associated with increased postoperative complications.

Background: The Department of Veterans Affairs is the largest US provider of hepatitis C treatment. Although antiviral regimens are becoming simpler, hepatitis C antivirals are not typically prescribed by primary care providers. The Veterans Affairs Extension for Community Health Outcomes (VA-ECHO) program was launched to promote primary care-based hepatitis C treatment using videoconferencing-based specialist support. We aimed to assess whether primary care provider participation in VA-ECHO was associated with hepatitis C treatment and sustained virologic response.Methods: We identified 4173 primary care providers (n = 152 sites) responsible for 38,753 patients with chronic hepatitis C infection. A total of 6431 patients had a primary care provider participating in VA-ECHO; 32,322 patients had an unexposed primary care provider. Exposure was modeled as a patient-level time-varying covariate. Patients became exposed after primary care provider participation in ≥1 VA-ECHO session. Multivariable Cox proportional hazards frailty modeling assessed the association between VA-ECHO exposure and hepatitis C treatment. Among treated patients, modified Poisson regression assessed the relationship between exposure and sustained virologic response.Results: After adjustment, exposed patients received significantly higher rates of antiviral treatment compared with unexposed patients (adjusted hazard ratio, 1.20; 95% confidence interval, 1.10-1.32; P <.01). The rate of primary care provider-initiated antiviral medication was 21.4% among treated patients reviewed on VA-ECHO teleconferences compared with 2.5% among unexposed patients (P <.01). No difference in adjusted rates of sustained virologic response was observed for patients with exposed primary care providers (P = .32), with similar crude rates for primary care providers versus specialists.Conclusions: National implementation of VA-ECHO was positively associated with hepatitis C treatment initiation by primary care providers, without differences in sustained virologic response.

The goal of this study was to describe the cohort of women prescribed PrEP at the Veterans Health Administration. We used a cross-sectional study of electronic health record data. We used descriptive statistics and calculated estimated average percent change by year of prescription. A total of 417 women were prescribed PrEP over the study period. The most substantial change over time in PrEP prescribing occurred among women aged 18-24, in Other race group, and in the Western US. Though PrEP prescribing increased since its approval, more research is needed to identify barriers and expand PrEP access for women Veterans., (© 2024.

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.

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., (© 2022 American Association for the Study of Liver Diseases.

Backgruound: We aimed to investigate the association of hepatic steatosis with liver fibrosis and to assess the interactive effects of hepatic steatosis and insulin resistance on liver fibrosis in a nationally representative sample of United States adults., Methods: We conducted a cross-sectional analysis using data from National Health and Nutrition Examination Survey 2017 to 2018, which for the first time included transient elastography to assess liver stiffness and hepatic steatosis. We evaluated the association between hepatic steatosis (using controlled attenuation parameter [CAP]) and clinically significant liver fibrosis (defined as liver stiffness ≥7.5 kPa) using logistic regression with an interaction term for hepatic steatosis and insulin resistance (defined as homeostatic model assessment of insulin resistance ≥3.0)., Results: Among adults undergoing transient elastography (n=2,023), 45.9% had moderate or greater hepatic steatosis and 11.3% had clinically significant liver fibrosis. After adjustment for demographic and metabolic factors, the odds of significant liver fibrosis increased as CAP score rose (odds ratio, 1.35 per standard deviation increment; 95% confidence interval, 1.11 to 1.64). We detected a significant interaction effect between CAP score and insulin resistance on the probability of significant liver fibrosis (P=0.016 for interaction). The probability of significant liver fibrosis increased in the presence of insulin resistance with increasing CAP score, while those without insulin resistance had low probability of significant liver fibrosis, even with high CAP scores., Conclusion: Individuals with hepatic steatosis had higher odds of fibrosis when insulin resistance was present. Our findings emphasize the importance of the metabolic aspects of the disease on fibrosis risk and suggest a need to better identify patients with metabolic associated fatty liver disease.

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., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2019 Wolters Kluwer Health, Inc.

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., Competing Interests: Conflicts of interest The authors declare no conflicts of interest that pertain to this work.

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.

Objective: To determine the relationship between travel distance and surveillance for hepatocellular carcinoma among veterans with cirrhosis., Data Sources: Veterans Health Administration (VHA) inpatient and outpatient administrative data were linked to geocoded enrollee files. CMS-VHA merged data were used to assess receipt of Medicare-financed non-VA imaging., Study Design: A retrospective cohort of US veterans diagnosed with cirrhosis between 2009 and 2015 was examined. First available abdominal imaging following the diagnosis of cirrhosis was analyzed separately as a function of travel distance to the nearest VA medical center (VAMC) and to the patient's assigned VA primary care provider. Veterans with dual use of Medicare and VA services were also examined for receipt of imaging outside of the VA., Principal Findings: Veterans who resided more than 30 miles from the nearest VAMC were less likely to receive any imaging for HCC surveillance. Among dual users, increased travel distance between the patient's residence and nearest VAMC was associated with an increased likelihood of receiving any abdominal imaging at non-VA facilities., Conclusion: Increased travel distance to the nearest VA medical center reduces the likelihood of receiving imaging for HCC surveillance in cirrhotic veterans. Future efforts should focus on reducing geographic barriers to HCC surveillance., (© Health Research and Educational Trust.)

Background: Cases of HIV, while infrequent, have been reported during tenofovir disoproxil fumarate/emtricitabine use as pre-exposure prophylaxis (PrEP). We describe the incidence of HIV and patterns of PrEP use within the Veterans Health Administration (VHA)., Methods: We conducted a retrospective cohort study among persons initiating PrEP in the VHA between July 2012 and April 2016 using national VHA data. We defined time on PrEP and time at risk of HIV exposure as the total time from the first PrEP fill to exhaustion of supply of the final PrEP prescription. We identified incident cases of HIV infection after PrEP initiation based on laboratory data. Medication adherence measures and days without pills were calculated using pharmacy fill data. We used a chart review to determine patient-reported PrEP use around the time of diagnosis., Results: We identified 825 unique patients initiating PrEP; they were 97% men and 67% white, with a mean age of 41 years. Six HIV infections were observed during the study period, yielding an HIV incidence of 0.8 (Poisson exact 95% confidence interval: 0.3 to 1.8) cases per 100 person-years. Two cases occurred during active PrEP use by self-report and perfect adherence based on fill data. Both were infected with viruses containing the M184V mutation. Four additional cases were diagnosed after self-reported discontinuation., Conclusions: HIV infection was rare in a nationwide cohort of PrEP users. Although most of the infections occurred during inconsistent PrEP use, infections during periods of high measured adherence were also observed. These findings highlight the importance of PrEP persistence during periods of risk.

Background: The Veterans Health Administration (VHA) provides care to the one of the largest cohorts of patients with advanced liver disease (ALD) in the USA., Aims: We performed a national survey to assess system-wide strengths and barriers to care for Veterans with ALD in this national integrated healthcare setting., Methods: A 52-item survey was developed to assess access and barriers to care in Veterans with ALD. The survey was distributed to all VHA medical centers in 2015. Results were analyzed using descriptive statistics., Results: One hundred and fifty-three sites responded to this survey. Multidisciplinary services were available on-site at > 80% of sites. Ninety-five percent of sites had mental health and addictions treatment available, with 14% co-locating these services within the liver clinic. Few sites (< 25%) provided pharmacologic treatment for alcohol use disorder in primary care or hepatology settings. Seventy-two percent of sites reported at least one barrier to liver-related care. Of the sites reporting at least one barrier, 53% reported barriers to liver transplant referral, citing complex processes and lack of staff/resources to coordinate referrals. Palliative care was widely available, but 61% of sites reported referring < 25% of their patients with ALD for palliative services., Conclusion: Multidisciplinary services for Veterans with ALD are widely available at VHA sites, though barriers to optimal care remain. Opportunities for improvement include the expansion of providers with hepatology expertise, integrating pharmacotherapy for alcohol use disorder into hepatology and primary care, streamlining the transplant referral process, and expanding palliative care referrals for patients with ALD.

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., (Copyright © 2019 AGA Institute.

To quantify health care facility-level variation in pre-exposure prophylaxis (PrEP) use in the Veteran's Health Administration (VHA); to identify facility characteristics associated with PrEP use. Retrospective analysis of the health care facility-level rate of PrEP initiation in VHA through June 30, 2017. Standardized PrEP initiation rates were used to rank facilities. Characteristics of facilities, prescribers, and PrEP recipients were examined within quartiles. Multiple linear regression was used to identify associations between facility characteristics and PrEP use. We identified 1600 PrEP recipients. Mean PrEP initiation rate was 20.0/100,000 (SD 22.8), ranging from 3.0/100,000 (SD 2.0) in the lowest quartile to 48.1/100,000 (SD 29.1) in the highest. PrEP prescribing was positively associated with proportions of urban dwellers and individuals < 45, tertiary care status, and location. Variability in PrEP uptake across a national health care system highlights opportunities to expand access in non-tertiary care facilities and underserved areas.

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., (Copyright © 2019 AGA Institute. Published by Elsevier Inc.

Objectives: To report demographics, regional variations, and indications for preexposure prophylaxis (PrEP) use for HIV prevention in the Veterans Health Administration (VHA)., Methods: We identified persons initiating tenofovir/emtricitabine for the PrEP indication in the United States between July 2012 and April 2016 in a VHA national database. We stratified PrEP use by provider type and VHA region. We calculated PrEP initiation rate for each region with VHA population data., Results: Of the 825 persons who initiated PrEP during the observation period, 67% were White and 76% were men who have sex with men. People who inject drugs and transgender persons represented less than 1% each of the cohort. The majority of PrEP initiations were clustered in 3 states, leading with California (28%) followed by Florida (9%) and Texas (8%). The Southeast had one of the lowest PrEP rates at 10 PrEP initiations per 100 000 persons in care. Infectious disease specialists issued more than two thirds of index PrEP prescriptions., Conclusions: Uptake of PrEP in the VHA is uneven along geographic and risk categories. Understanding the reasons behind these gaps will be key in expanding the use of this important prevention tool.

Background & Aims: We investigated the real-world effectiveness of sofosbuvir, ledipasvir/sofosbuvir, and paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD) in treatment of different subgroups of patients infected with hepatitis C virus (HCV) genotypes 1, 2, 3, or 4., Methods: We performed a retrospective analysis of data from 17,487 patients with HCV infection (13,974 with HCV genotype 1; 2131 with genotype 2; 1237 with genotype 3; and 135 with genotype 4) who began treatment with sofosbuvir (n = 2986), ledipasvir/sofosbuvir (n = 11,327), or PrOD (n = 3174), with or without ribavirin, from January 1, 2014 through June 20, 2015 in the Veterans Affairs health care system. Data through April 15, 2016 were analyzed to assess completion of treatments and sustained virologic response 12 weeks after treatment (SVR12). Mean age of patients was 61 ± 7 years, 97% were male, 52% were non-Hispanic white, 29% were non-Hispanic black, 32% had a diagnosis of cirrhosis (9.9% with decompensated cirrhosis), 36% had a Fibrosis-4 index score >3.25 (indicator of cirrhosis), and 29% had received prior antiviral treatment., Results: An SVR12 was achieved by 92.8% (95% confidence interval [CI], 92.3%-93.2%) of subjects with HCV genotype 1 infection (no significant difference between ledipasvir/sofosbuvir and PrOD regimens), 86.2% (95% CI, 84.6%-87.7%) of those with genotype 2 infection (treated with sofosbuvir and ribavirin), 74.8% (95% CI, 72.2%-77.3%) of those with genotype 3 infection (77.9% in patients given ledipasvir/sofosbuvir plus ribavirin, 87.0% in patients given sofosbuvir and pegylated-interferon plus ribavirin, and 70.6% of patients given sofosbuvir plus ribavirin), and 89.6% (95% CI 82.8%-93.9%) of those with genotype 4 infection. Among patients with cirrhosis, 90.6% of patients with HCV genotype 1, 77.3% with HCV genotype 2, 65.7% with HCV genotype 3, and 83.9% with HCV genotype 4 achieved an SVR12. Among previously treated patients, 92.6% with genotype 1; 80.2% with genotype 2; 69.2% with genotype 3; and 93.5% with genotype 4 achieved SVR12. Among treatment-naive patients, 92.8% with genotype 1; 88.0% with genotype 2; 77.5% with genotype 3; and 88.3% with genotype 4 achieved SVR12. Eight-week regimens of ledipasvir/sofosbuvir produced an SVR12 in 94.3% of eligible patients with HCV genotype 1 infection; this regimen was underused., Conclusions: High proportions of patients with HCV infections genotypes 1-4 (ranging from 75% to 93%) in the Veterans Affairs national health care system achieved SVR12, approaching the results reported in clinical trials, especially in patients with genotype 1 infection. An 8-week regimen of ledipasvir/sofosbuvir is effective for eligible patients with HCV genotype 1 infection and could reduce costs. There is substantial room for improvement in SVRs among persons with cirrhosis and genotype 2 or 3 infections., (Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Background & Aims: Cirrhosis and hepatocellular carcinoma (HCC) are predicted to increase in the United States but the accuracy of prior forecasts and the contributions from various liver disease etiologies remain unclear. We aimed to determine the burden of cirrhosis and HCC according to underlying cause from 2001 to 2013., Methods: We developed a national retrospective cohort of Veterans Affairs (VA) patients with the diagnosis of cirrhosis (n = 129,998) or HCC (n = 21,326) from 2001 to 2013. We used laboratory results, International Classification of Diseases, ninth edition (ICD-9) codes, and body mass index to identify underlying etiologies., Results: In 2013, VA provided care to 5,720,614 individuals, of whom 60,553 (1.06%) had cirrhosis and 7,670 (0.13%) had HCC. Hepatitis C virus (HCV) was present in an increasing proportion of cirrhosis and HCC between 2001 and 2013, reaching 48% of cirrhosis cases and deaths and 67% of HCC cases and deaths by 2013. Cirrhosis prevalence nearly doubled from 2001 to 2013 (664 to 1058 per 100,000 enrollees), driven by HCV and nonalcoholic fatty liver disease (NAFLD). Cirrhosis incidence ranged from 159 to 193 per 100,000 patient-years. Deaths in patients with cirrhosis increased from 83 to 126 per 100,000 patient-years, largely driven by HCV. HCC incidence was 2.5-fold increased from 17 to 45 per 100,000 patient-years. HCC mortality tripled from 13 to 37 per 100,000 patient-years, driven overwhelmingly by HCV, with much smaller contributions from NAFLD and alcoholic liver disease., Conclusions: Cirrhosis prevalence and mortality and HCC incidence and mortality increased from 2001 to 2013, driven by HCV, with a smaller contribution from NAFLD. If current trends continue, cirrhosis prevalence will peak in 2021. Health care systems will need to accommodate rising numbers of patients with cirrhosis and HCC., (Copyright © 2015 AGA Institute.

Background & Aims: We investigated the real-world effectiveness of triple therapy regimens against hepatitis C virus (HCV) and compared rates of sustained virologic response (SVR) between telaprevir-based and boceprevir-based regimens in a population-based study., Methods: We analyzed data on all patients in the Veterans Administration healthcare system who were infected with HCV genotype 1 and began treatment with pegylated interferon, ribavirin, and either boceprevir (n = 3696, 83%) or telaprevir (n = 759, 17%) from June 2011 to February 2013., Results: Patients treated with telaprevir were more likely to have baseline characteristics associated with not achieving SVR than patients treated with boceprevir. Fewer than half of patients eligible for short-duration regimens (28 weeks for boceprevir, 24 weeks for telaprevir) successfully completed treatment (37% for boceprevir, 27.5% for telaprevir); ∼25% discontinued early, and the remaining patients were treated for longer durations. Of the patients who were supposed to complete 48-week regimens, only 35% of boceprevir-treated and 34% of telaprevir-treated patients completed >44 weeks. The rate of SVR was 51.5% overall, 42.7% among patients with cirrhosis, 56.8% among treatment-naive patients, 64.2% among prior relapsers, 31.7% among prior partial responders, and 29.8% among prior null responders. There were no significant differences in rate of SVR between patients given boceprevir or telaprevir in the entire population or among subgroups. The most important predictors of failure to achieve SVR were IL28B genotype, high viral load, black race, diabetes, high aspartate aminotransferase to platelet ratio index or FIB-4 scores, low platelet counts, or low levels of low-density lipoprotein cholesterol. Erythropoietin use was not associated with SVR., Conclusions: In a nationwide analysis of veterans with HCV genotype 1 infection, rates of SVR were similar for those treated with boceprevir vs telaprevir. However, rates of treatment completion and SVR in real clinical practice were substantially lower than those in clinical trials., (Copyright © 2014 AGA Institute. Published by Elsevier Inc.

Background: Patients who screen positive for alcohol misuse on the Alcohol Use Disorder Identification Test Consumption Questionnaire (AUDIT-C ≥5 points) have significantly increased postoperative complications. Severe alcohol misuse (AUDIT-C ≥9 points) is associated with increased postoperative health care use; however, little is known about the prevalence of alcohol misuse in demographic and clinical subgroups of surgical patients., Methods: The prevalence of alcohol misuse was evaluated among 10,284 patients (9,771 men and 513 women) who underwent major noncardiac surgery in Veterans Affairs (VA) hospitals during the fiscal years 2004 to 2006 and completed the AUDIT-C. Sex-stratified analyses evaluated prevalence rates of alcohol misuse (AUDIT-C ≥5) and severe misuse (AUDIT-C ≥9) across demographic and clinical subgroups., Results: Overall, 1,607 (16%) men and 24 (5%) women screened positive for alcohol misuse (AUDIT-C ≥5) in the year before operation, with 4% and 2% screening positive for severe misuse (AUDIT-C ≥9), respectively. Alcohol misuse was more common among men who were <60 years of age, divorced or separated, current smokers, or American Stoke Association class 1 or 2, and those with cirrhosis/hepatitis or substance use disorders. Among patients with alcohol misuse, 36% of men and 58% of women were American Society of Anesthesiologists class 1 or 2, and most did not have diagnoses that were commonly associated with alcohol misuse., Conclusion: Alcohol misuse is relatively common in male surgical patients. Moreover, surgical patients undergoing operation who screen positive for alcohol misuse are often relatively healthy, without health problems that might alert providers to their alcohol misuse in the absence of screening., (Copyright © 2012 Mosby, Inc.

Background: Patients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed., Objective: To evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire-up to a year before surgery-were associated with the risk of postoperative complications., Design: This is a cohort study., Setting and Participants: Male Veterans Affairs (VA) patients were eligible if they had major noncardiac surgery assessed by the VA's Surgical Quality Improvement Program (VASQIP) in fiscal years 2004-2006, and completed the AUDIT-C alcohol screening questionnaire (0-12 points) on a mailed survey within 1 year before surgery., Main Outcome Measure: One or more postoperative complication(s) within 30 days of surgery based on VASQIP nurse medical record reviews., Results: Among 9,176 eligible men, 16.3% screened positive for alcohol misuse with AUDIT-C scores ≥ 5, and 7.8% had postoperative complications. Patients with AUDIT-C scores ≥ 5 were at significantly increased risk for postoperative complications, compared to patients who drank less. In analyses adjusted for age, smoking, and days from screening to surgery, the estimated prevalence of postoperative complications increased from 5.6% (95% CI 4.8-6.6%) in patients with AUDIT-C scores 1-4, to 7.9% (6.3-9.7%) in patients with AUDIT-Cs 5-8, 9.7% (6.6-14.1%) in patients with AUDIT-Cs 9-10 and 14.0% (8.9-21.3%) in patients with AUDIT-Cs 11-12. In fully-adjusted analyses that included preoperative covariates potentially in the causal pathway between alcohol misuse and complications, the estimated prevalence of postoperative complications increased significantly from 4.8% (4.1-5.7%) in patients with AUDIT-C scores 1-4, to 6.9% (5.5-8.7%) in patients with AUDIT-Cs 5-8 and 7.5% (5.0-11.3%) among those with AUDIT-Cs 9-10., Conclusions: AUDIT-C scores of 5 or more up to a year before surgery were associated with increased postoperative complications.
