RESUMO
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: 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: Little is known about national patterns of sexually transmitted infection (STI) testing and infections among people with substance use disorders (SUDs). METHODS: This study used a national retrospective analysis of people with SUDs receiving healthcare in the Veterans Health Administration in 2019 (N = 485,869). We describe testing rates, test positivity, and case rates for gonorrhea, chlamydia, syphilis, and HIV among individuals with alcohol, opioid, cocaine, and noncocaine stimulant use disorders in a national cohort of Veterans Health Administration patients. RESULTS: Test and case rates for all STIs were highest among people with noncocaine stimulant use. People with alcohol use disorder had the lowest testing rates but intermediate incidence for all STIs. People with multiple SUDs had higher incidence of all STIs than those with single SUDs. Mental health diagnoses and houselessness were common. The HIV test positivity was 0.14% to 0.36% across SUD groups. CONCLUSIONS: Sexually transmitted infection testing rates between SUD groups were discordant with their respective case rates. High STI rates in people with SUDs suggest a need for more comprehensive testing, particularly for those with noncocaine stimulant use and those with comorbid houselessness or mental health diagnoses.

Background: We performed a retrospective study of chlamydia, gonorrhea, syphilis, and human immunodeficiency virus (HIV) testing in the Veterans Health Administration (VHA) during 2019-2021. Methods: We determined the annual number of chlamydia, gonorrhea, syphilis, and HIV tests from 2019 through 2021 using electronic health record data. We calculated rates by age, birth sex, race, census region, rurality, HIV status, and use of preexposure prophylaxis. Results: The VHA system experienced a 24% drop in chlamydia/gonorrhea testing, a 25% drop in syphilis testing, and a 29% drop in HIV testing in 2020 versus 2019. By the conclusion of 2021, testing rates had recovered to 90% of baseline for chlamydia/gonorrhea, 91% for syphilis, and 88% for HIV. Declines and subsequent improvements in sexually transmitted infection (STI) testing occurred unequally across age, sex, race, and geographic groups. Testing for all 4 STIs in 2021 remained below baseline in rural Veterans. Excluding those aged <25 years, women experienced a steeper decline and slower recovery in chlamydia/gonorrhea testing relative to men, but quicker recovery in HIV testing. Asian Americans and Hawaiian/Pacific Islanders had a steeper decline and a slower recovery in testing for chlamydia/gonorrhea. Black and White Veterans had slower recovery in HIV testing compared with other race groups. People living with HIV experienced a smaller drop in testing for syphilis compared with people without HIV, followed by a near-total recovery of testing by 2021. Conclusions: After dramatic reductions from 2019 to 2020, STI testing rates returned to near-baseline in 2021. Testing recovery lagged in rural, female, Asian American, Hawaiian/Pacific Islander, and Black Veterans.

RESUMO
BACKGROUND: Analyses of electronic medical databases often compare clinical practice to guideline recommendations. These analyses have a limited ability to simultaneously evaluate many interconnected medical decisions. We aimed to overcome this limitation with an alternative method and apply it to the diagnostic workup of HIV, where misuse can contribute to HIV transmission, delay care, and incur unnecessary costs. METHODS: We used graph theory to assess patterns of HIV diagnostic testing in a national healthcare system. We modeled the HIV diagnostic testing guidelines as a directed graph. Each node in the graph represented a test, and the edges pointed from one test to the next in chronological order. We then graphed each patient's HIV testing. This set of patient-level graphs was aggregated into a single graph. Finally, we compared the two graphs, the first representing the recommended approach to HIV diagnostic testing and the second representing the observed patterns of HIV testing, to assess for clinical practice deviations. RESULTS: The HIV diagnostic testing of 1.643 million patients provided 8.790 million HIV diagnostic test results for analysis. Significant deviations from recommended practice were found including the use of HIV resistance tests (n = 3,007) and HIV nucleic acid tests (n = 16,567) instead of the recommended HIV screen. CONCLUSIONS: We developed a method that modeled a complex medical scenario as a directed graph. When applied to HIV diagnostic testing, we identified deviations in clinical practice from guideline recommendations. The model enabled the identification of intervention targets and prompted systemwide policy changes to enhance HIV detection.

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: 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: To measure the incidence of syphilis diagnoses among people with HIV vs those without HIV in a national multiyear retrospective cohort. METHODS: Treponemal and nontreponemal tests, HIV status, and demographic data were identified among all individuals receiving Veterans Health Administration (VHA) care between January 1, 2009, and December 31, 2019. Syphilis testing rates and incident syphilis diagnoses as defined by a laboratory algorithm were stratified by HIV status. RESULTS: Syphilis was diagnosed in 1.2% (nâ =â 2283) of 194 322 tested individuals in VHA care in 2019. Among individuals with HIV tested for syphilis, 6.1% met criteria for syphilis compared with 0.7% without HIV. Syphilis incidence in 2019 was 35/100 000, a 17% increase from 2009 (30/100 000). In 2019, syphilis incidence was 3381 per 100 000 persons among individuals with HIV and 19 per 100 000 in those without HIV. CONCLUSIONS: Using a laboratory-based diagnostic algorithm, a 178-fold difference in syphilis incidence was observed between individuals with and without HIV in 2019. US syphilis incidence data that incorporate HIV status are needed. Interventions to monitor and prevent sexually transmitted infections should address the role of HIV status.
RESUMO
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.

CONTEXT.: Disease guidelines specify universal alanine aminotransferase (ALT) thresholds for clinical decision-making, yet the effect of variability among ALT analyzers remains unclear. OBJECTIVE.: To compare ALT results from different analyzers from 2012-2017. DESIGN.: Veterans Health Administration (VHA) laboratories perform external ALT proficiency testing using standardized College of American Pathologists (CAP) samples in analyzers by 5 manufacturers. In this operational analysis, we evaluated 22 950 ALT values from 80 independent CAP samples tested at 223 laboratories. Using mixed effects modeling, we estimated the association between analyzer manufacturer and CAP outcome, adjusting for manufacturer, facility, and calendar year. We performed subgroup analyses on CAP samples with overall means near clinical guideline-specified thresholds, including less than 50 U/L (n = 10) and less than 35 U/L (n = 5). RESULTS.: The VHA used Abbott Laboratories (n = 3175; 14%), Beckman Coulter Diagnostics (n = 8723; 38%), Roche Diagnostics (n = 2595; 11%), Siemens Healthineers USA (n = 5713; 25%), and Vitros/Ortho Clinical Diagnostics (n = 2744; 12%) analyzers. The CAP samples (n = 80 samples, n = 22 950 tests) covered a wide range of mean ALT values (21-268 U/L). The average difference in mean ALT value per sample between the highest-reading and lowest-reading manufacturers was 15.4 U/L (SD = 1.8) for the 10 samples with mean ALT less than 50 U/L, and it was 10.4 U/L (SD = 3.6) overall (n = 80). In linear mixed effects modeling, we found statistically significant differences in ALT values between the different manufacturers in each year. CONCLUSIONS.: We found statistically and clinically meaningful differences between analyzers across the ALT spectrum in each year, including at ALT levels lower than 50 U/L and lower than 35 U/L. Universal ALT thresholds should be avoided as a trigger for clinical action until differences between analyzers can be resolved.

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.

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: 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.

Although widespread hepatitis A vaccination has dramatically decreased infection rates, a large proportion of VA patients in traditionally high-risk groups remains susceptible to infection.
RESUMO
To increase access, the National PrEP Working Group is expanding outreach outside of primary care and among nonspecialists, ensuring uniformly high-quality care and targeting high-risk populations.
RESUMO
Enhancing care of veterans infected with hepatitis B virus who are in VHA care includes providing clinical guidance, informatics tools, patient monitoring, and continuous evaluation of care.
