RESUMEN
We sought to operationalize and validate data-driven approaches for identifying transgender individuals in the Veterans Health Administration (VHA) of the US Department of Veterans Affairs (VA) through a retrospective analysis using VA administrative data from 2006-2018. Besides diagnoses of gender identity disorder (GID), a combination of non-GID data elements was used to identify potentially transgender veterans, including 1) an International Classification of Diseases (Ninth or Tenth Revision) code of endocrine disorder, unspecified or not otherwise specified; 2) receipt of sex hormones not associated with the sex documented in the veteran's records (gender-affirming hormone therapy); and 3) a change in the veteran's administratively recorded sex. Both GID and non-GID data elements were applied to a sample of 13,233,529 veterans utilizing the VHA of the VA between January 2006 and December 2018. We identified 10,769 potentially transgender veterans. Based on a high positive predictive value for GID-coded veterans (83%, 95% confidence interval: 77, 89) versus non-GID-coded veterans (2%, 95% confidence interval: 1, 11) from chart review validation, the final analytical sample comprised only veterans with a GID diagnosis code (n = 9,608). In the absence of self-identified gender identity, findings suggest that relying entirely on GID diagnosis codes is the most reliable approach for identifying transgender individuals in the VHA of the VA.

OBJECTIVE: Electronic consultations (e-consults) are commonly used to obtain endocrinology input on clinical questions without a face-to-face visit, but sparse data exist on the resultant quality of care for specific conditions. We examined workups resulting in a thyroid nodule fine-needle aspiration (FNA) biopsy to investigate whether endocrinology e-consults were more timely and similarly guideline-concordant compared with endocrinology face-to-face visits and whether endocrinology e-consults were more guideline-concordant compared with workups without endocrinology input. METHODS: We retrospectively reviewed charts of 302 thyroid FNA biopsies conducted in the Veterans Affairs health system between May 1, 2017, and February 4, 2020 (e-consult, n = 99; face-to-face visit, n = 100; no endocrinology input, n = 103). We used t tests to compare timeliness, χ2 tests to compare the proportion of guideline-concordant workups, and multivariable linear and logistic models to control for demographic factors. RESULTS: FNAs preceded by an endocrinology e-consult had more timely workups compared with those preceded by endocrinology face-to-face visits in terms of days elapsed between referral and FNA biopsy (geometric mean 44.7 days vs 61.7 days, P = .01). The difference in the summary measure of guideline concordance across groups was not statistically significant (P =.38). CONCLUSION: E-consults were faster than face-to-face consults and similarly guideline-concordant compared with both face-to-face consults and no endocrinology input for workups resulting in FNA. Decisions about the appropriate use of e-consults for thyroid nodules should take into account these data while also considering the potential benefits of direct patient-endocrinologist interaction for complex situations.

BACKGROUND: Inappropriate testosterone use and variations in testosterone prescribing patterns exist in the Veterans Health Administration (VHA) despite the presence of clinical guidelines. OBJECTIVE: We examined system and clinician factors that contribute to patterns of potentially inappropriate testosterone prescribing in VHA. DESIGN: Qualitative study using a positive deviance approach to understand practice variation in high- and low-testosterone prescribing sites. PARTICIPANTS: Twenty-two interview participants included primary care and specialty clinicians, key opinion leaders, and pharmacists at 3 high- and 3 low-testosterone prescribing sites. APPROACH: Semi-structured phone interviews were conducted, transcribed, and coded using a priori theoretical constructs and emergent themes. Case studies were developed for each site and a cross-case matrix was created to evaluate variation across high- and low-prescribing sites. KEY RESULTS: We identified four system-level domains related to variation in testosterone prescribing: organizational structures and processes specific to testosterone prescribing, availability of local guidance on testosterone prescribing, well-defined dissemination process for local testosterone polices, and engagement in best practices related to testosterone prescribing. Two clinician-level domains were also identified, specifically, structured initial testosterone prescribing process and specified follow-up testosterone prescribing process. High- and low-testosterone prescribing sites systematically varied in the four system-level domains, while the clinician-level domains looked similar across all sites. The third high-prescribing site was unusual in that it exhibited the four domains similar to the 3 low-prescribing sites at the time of our visit. This site had greatly reduced its prescribing of testosterone in the interim. CONCLUSIONS: Findings suggest that local organizational factors play an important role in influencing prescribing. Sites have the potential to transform their utilization patterns by providing access to specialty care expertise, an electronic health record-based system to facilitate guideline-concordant prescribing, well-defined dissemination processes for information, guidance from multiple sources, and clarity regarding best practices for prescribing.

Testosterone supplementation has been widely used in those infected with human immunodeficiency virus (HIV) for hypogonadism, and wasting. But with effective antiretroviral therapy and increasing recognition of atherosclerotic disease and adults infected with HIV, the risks of inappropriate testosterone use in HIV-infected patients are far better recognized than previously. Testosterone use has expanded among U.S. males, but few studies have examined prescribing in those infected with HIV. In a national cohort of males with at least one outpatient prescription in the Veterans Health Administration (VHA), we examined 9475 HIV-infected males, including 2484 who had received testosterone and a randomly selected 6991 who had not. For comparison, we identified 1,387,241 uninfected males (189,369 had received testosterone and a randomly selected 1,197,872 had not). We determined rates of new and prevalent testosterone use, and also examined the adequacy of the diagnostic evaluation that had preceded testosterone initiation among our HIV-infected and uninfected testosterone groups. Our main results were as follows. HIV-infected men had higher rates of initiation (0.8% vs. 0.4% in FY09; p < 0.001) and prevalence of testosterone use (2.2% vs. 0.8% in FY08; p < 0.001) compared to the uninfected men across the entire period. Trends of prescribing for both groups followed a similar pattern, rising from FY08, reaching a peak in FY13, and then dipping in FY 14. Only 1.1% of HIV-infected patients had a fully guideline-concordant workup before starting testosterone therapy, compared to 3.5% of uninfected patients (p < 0.001). In conclusion, testosterone use among HIV-infected patients in the VHA system rose to a peak in FY13 and has decreased somewhat since. Only a small minority of HIV-infected patients who receive testosterone therapy from VHA have undergone an appropriate workup before starting therapy, suggesting an opportunity for improvement.

Patients who attribute their symptoms to HIV medications, rather than disease, may be prone to switching antiretrovirals (ARVs) and experience poor retention/adherence to care. Gastrointestinal (GI) symptoms (e.g., nausea/vomiting) are often experienced as a side effect of ARVs, but little is known about the relationship of symptom attribution and bothersomeness to adherence. We hypothesized that attribution of a GI symptom to ARVs is associated with a reduction in adherence, and that this relationship is moderated by the bothersomeness of the symptom. Data for our analysis come from the pre-randomization enrollment period of a larger study testing an adherence improvement intervention. Analyses revealed that patients with diarrhea who attributed the symptom to ARVs (compared to those who did not) had significantly worse adherence. We did not find a significant moderating effect of bothersomeness on this relationship. Incorporating patient beliefs about causes of symptoms into clinical care may contribute to improved symptom and medication management, and better adherence.

BACKGROUND: There has been concern about the growing off-label use of testosterone. Understanding the context within which testosterone is prescribed may contribute to interventions to improve prescribing. OBJECTIVE: To evaluate patient characteristics associated with receipt of testosterone. DESIGN: Cross-sectional. SETTING: A national cohort of male patients, who had received at least one outpatient prescription within the Veterans Affairs (VA) system during Fiscal Year 2008- Fiscal Year 2012. PARTICIPANTS: The study sample consisted of 682,915 non-HIV male patients, of whom 132,764 had received testosterone and a random 10% sample, 550,151, had not. MAIN MEASURES: Conditions and medications associated with testosterone prescription. KEY RESULTS: Only 6.3% of men who received testosterone from the VA during the study period had a disorder of the testis, pituitary or hypothalamus associated with male hypogonadism. Among patients without a diagnosed disorder of hypogonadism, the use of opioids and obesity were the strongest predictors of testosterone prescription. Patients receiving >100 mg/equivalents of oral morphine daily (adjusted odds ratio = 5.75, p < 0.001) and those with body mass index (BMI) >40 kg/m2 (adjusted odds ratio = 3.01, p < 0.001) were more likely to receive testosterone than non-opioid users and men with BMI <25 kg/m2. Certain demographics (age 40-54, White race), comorbid conditions (sleep apnea, depression, and diabetes), and medications (antidepressants, systemic corticosteroids) also predicted a higher likelihood of testosterone receipt, all with an adjusted odds ratio less than 2 (p < 0.001). CONCLUSIONS: In the VA, 93.7% of men receiving testosterone did not have a diagnosed condition of the testes, pituitary, or hypothalamus. The strongest predictors of testosterone receipt (e.g., obesity, receipt of opioids), which though are associated with unapproved, off-label use, may be valid reasons for therapy. Interventions should aim to increase the proportion of testosterone recipients who have a valid indication.

BACKGROUND: Improved anticoagulation control with warfarin reduces adverse events and represents a target for quality improvement. No previous study has described an effort to improve anticoagulation control across a health system. OBJECTIVE: To describe the results of an effort to improve anticoagulation control in the New England region of the Veterans Health Administration (VA). METHODS: Our intervention encompassed 8 VA sites managing warfarin for more than 5000 patients in New England (Veterans Integrated Service Network 1 [VISN 1]). We provided sites with a system to measure processes of care, along with targeted audit and feedback. We focused on processes of care associated with site-level anticoagulation control, including prompt follow-up after out-of-range international normalized ratio (INR) values, minimizing loss to follow-up, and use of guideline-concordant INR target ranges. We used a difference-in-differences (DID) model to examine changes in anticoagulation control, measured as percentage time in therapeutic range (TTR), as well as process measures and compared VISN 1 sites with 116 VA sites located outside VISN 1. RESULTS: VISN 1 sites improved on TTR, our main indicator of quality, from 66.4% to 69.2%, whereas sites outside VISN 1 improved from 65.9% to 66.4% (DID 2.3%, P < 0.001). Improvement in TTR correlated strongly with the extent of improvement on process-of-care measures, which varied widely across VISN 1 sites. CONCLUSIONS: A regional quality improvement initiative, using performance measurement with audit and feedback, improved TTR by 2.3% more than control sites, which is a clinically important difference. Improving relevant processes of care can improve outcomes for patients receiving warfarin.

BACKGROUND: Prescribing of exogenous testosterone is increasing. Because of the risks associated with testosterone, it is important to follow evidence-based procedures when initiating therapy. OBJECTIVE: We evaluated whether dispensing of testosterone was preceded by appropriate ascertainment of androgen deficiency, and consideration of potential contraindications, in accordance with practice guidelines. RESEARCH DESIGN: A cross-sectional study. SETTING: All outpatient clinics within Veterans Affairs (VA) during fiscal years 2009-2012 (FY09-FY12). SUBJECTS: A total of 111,631 men who had not previously received testosterone from VA, and received at least 1 testosterone dispensing during the study period. A 1-year "look-back" period was used to check for diagnostic tests that occurred before the first fill. MEASURES: Proportion who underwent appropriate diagnostic evaluation of androgen deficiency and ascertainment of contraindications for testosterone therapy during the year before receiving their first testosterone dispensing. RESULTS: New testosterone dispensing in VA increased from 20,437 in FY09 to 36,394 in FY12. Only 3.1% of men who received testosterone had 2 or more low (total or free) testosterone levels in the morning, LH and/or FSH level measured, and no contraindications to testosterone therapy. A total of 16.5% did not have their testosterone level checked at all. Among those prescribed therapy, 1.4% had prostate cancer, 7.6% had obstructive sleep apnea, and 3.5% had elevated hematocrit at baseline. CONCLUSIONS: Only a small proportion of men receiving testosterone in VA underwent appropriate testing, and some received this therapy despite important contraindications. Promoting a more uniform application of clinical guidelines may facilitate appropriate use of testosterone.

BACKGROUND: Warfarin is received by millions of patients in the United States and elsewhere and will remain the most commonly used anticoagulant for the foreseeable future. Percent time in therapeutic range (TTR) with warfarin is increasingly used as a performance measure. However, stakeholders have expressed concern that TTR lags behind changes in performance. Work in a larger study focused on the impact of shortening the conventional measurement period for TTR. METHODS: Some 124 sites within the Department of Veterans Affairs (VA) were examined during a seven-year period (fiscal years [FYs] 2008-2014 (April 1, 2007-September 30, 2014). The duration of time segments (2, 3, 4, 6 months) used to calculate TTR were varied, and these four durations were compared in terms of the number of patients retained per site, mean and median site TTR, and site performance rankings. RESULTS: Data were obtained on 295,237 unique patients who received anticoagulation. As the calculation window shortened, patients with better control (that is, higher TTR) were selectively excluded from the measurement because their laboratory values were more widely spaced. Site mean TTR was highest when the most patients were included (6 months: 950 patients; TTR 65.2%) and lowest when the fewest patients were included (2 months: 567 patients; TTR 60.0%). However, the 3-, 4-, and 6-month segments achieved similar results, each of which included more than 800 patients per site, with mean TTR across a narrow range (64.9%-65.2%). Site rankings were less highly correlated between the 2-month period and longer periods (r = 0.7- 0.8) but were otherwise 0.95 or higher, with a nearly perfect correlation (0.985) between the 4- and 6-month periods. CONCLUSIONS: When TTR is used to measure site-level performance, comparable results can be achieved using a 4- or a 6-month measurement period. On the basis of these results, the use of a 4-month period for future measurement efforts is recommended.

BACKGROUND: Patients with mental health conditions (MHCs) experience poor anticoagulation control when using warfarin, but we have limited knowledge of the association between specific mental illness and warfarin treatment outcomes. OBJECTIVE: To examine the relationship between the severity of MHCs and outcomes of anticoagulation therapy. DESIGN: Retrospective cohort analysis. PARTICIPANTS: We studied 103,897 patients on warfarin for 6 or more months cared for by the Veterans Health Administration during fiscal years 2007-2008. We identified 28,216 patients with MHCs using ICD-9 codes: anxiety disorders, bipolar disorder, depression, post-traumatic stress disorder, schizophrenia, and other psychotic disorders. MAIN MEASURES: Outcomes included anticoagulation control, as measured by percent time in the therapeutic range (TTR), as well as major hemorrhage. Predictors included different categories of MHC, Global Assessment of Functioning (GAF) scores, and psychiatric hospitalizations. KEY RESULTS: Patients with bipolar disorder, depression, and other psychotic disorders experienced TTR decreases of 2.63 %, 2.26 %, and 2.92 %, respectively (p < 0.001), after controlling for covariates. Patients with psychotic disorders other than schizophrenia experienced increased hemorrhage after controlling for covariates [hazard ratio (HR) 1.24, p = 0.03]. Having any MHC was associated with a slightly increased hazard for hemorrhage (HR 1.19, p < 0.001) after controlling for covariates. CONCLUSION: Patients with specific MHCs (bipolar disorder, depression, and other psychotic disorders) experienced slightly worse anticoagulation control. Patients with any MHC had a slightly increased hazard for major hemorrhage, but the magnitude of this difference is unlikely to be clinically significant. Overall, our results suggest that appropriately selected patients with MHCs can safely receive therapy with warfarin.

RESUMEN
Background: Gender-affirming hormone therapy (GAHT) is a common medical intervention sought by transgender and gender diverse (TGD) individuals. Initiating GAHT in accordance with clinical guideline recommendations ensures delivery of high-quality care. However, no prior studies have examined how current GAHT initiation compares to recommended GAHT initiation. Objective: This study assessed guideline concordance around feminizing and masculinizing GAHT initiation in the Veterans Health Administration (VHA). Methods: The sample included 4,676 veterans with a gender identity disorder diagnosis who initiated feminizing (n=3,547) and masculinizing (n=1,129) GAHT between 2007 and 2018 in VHA. Demographics and health conditions on veterans receiving feminizing and masculinizing GAHT were assessed. Proportion of guideline concordant veterans on six VHA guidelines on feminizing and masculinizing GAHT initiation were determined. Results: Compared to veterans receiving masculinizing GAHT, a higher proportion of veterans receiving feminizing GAHT were older (≥60 years: 23.7% vs. 6.3%), White non-Hispanic (83.5% vs. 57.6%), and had a higher number of comorbidities (≥7: 14.0% vs. 10.6%). A higher proportion of veterans receiving masculinizing GAHT were Black non-Hispanic (21.5% vs. 3.5%), had posttraumatic stress disorder (43.0% vs. 33.9%) and positive military sexual trauma (33.5% vs.16.8%; all p-values<0.001) than veterans receiving feminizing GAHT. Among veterans who started feminizing GAHT with estrogen, 97.0% were guideline concordant due to no documentation of contraindication, including venous thromboembolism, breast cancer, stroke, or myocardial infarction. Among veterans who started spironolactone as part of feminizing GAHT, 98.1% were guideline concordant as they had no documentation of contraindication, including hyperkalemia or acute renal failure. Among veterans starting masculinizing GAHT, 90.1% were guideline concordant due to no documentation of contraindications, such as breast or prostate cancer. Hematocrit had been measured in 91.8% of veterans before initiating masculinizing GAHT, with 96.5% not having an elevated hematocrit (>50%) prior to starting masculinizing GAHT. Among veterans initiating feminizing and masculinizing GAHT, 91.2% had documentation of a gender identity disorder diagnosis prior to GAHT initiation. Conclusion: We observed high concordance between current GAHT initiation practices in VHA and guidelines, particularly for feminizing GAHT. Findings suggest that VHA clinicians are initiating feminizing GAHT in concordance with clinical guidelines. Future work should assess guideline concordance on monitoring and management of GAHT in VHA.

Purpose: This study aimed to examine patient characteristics associated with receipt of gender-affirming hormone therapy in the Veterans Health Administration (VHA). Methods: This cross-sectional study included a national cohort of 9555 transgender and gender diverse (TGD) patients with TGD-related diagnosis codes who received care in the VHA from 2006 to 2018. Logistic regression models were used to determine the association of health conditions and documented social stressors with receipt of gender affirming hormone therapy. Results: Of the 9555 TGD patients, 57.4% received gender-affirming hormone therapy in the VHA. In fully adjusted models, patients who had following characteristics were less likely to obtain gender-affirming hormones in the VHA: Black, non-Hispanic versus white (adjusted odds ratio [aOR]: 0.61; 95% confidence interval [CI]: 0.52-0.72), living in the Northeast versus the West (aOR: 0.72; 95% CI: 0.62-0.84), a documented drug use disorder (aOR: 0.56; 95% CI: 0.47-0.68), ≥3 versus no comorbidities (aOR: 0.44; 95% CI: 0.34-0.57), and ≥3 versus no social stressors (aOR: 0.42; 95% CI: 0.30-0.58; all p<0.001). Younger patients aged 21-29 years were almost 3 times more likely to receive gender affirming hormone therapy in the VHA than those aged ≥60 (aOR: 2.98; 95% CI: 2.55-3.47; p<0.001). Conclusion: TGD individuals who were older, Black, non-Hispanic, and had more comorbidities and documented social stressors were less likely to receive gender-affirming hormone therapy in the VHA. Further understanding of patient preferences in addition to clinician- and site-level determinants that may impact access to gender-affirming hormone therapy for TGD individuals in the VHA is needed.
RESUMEN
PURPOSE: The complexity of patients with mental healthcare needs cared for by clinical pharmacists is not well delineated. We evaluated the complexity of patients with schizophrenia, bipolar disorder, and major depressive disorder (MDD) in Veterans Affairs (VA) cared for by mental health clinical pharmacist practitioners (MH CPPs). METHODS: Patients at 42 VA sites with schizophrenia, bipolar disorder, or MDD in 2016 through 2019 were classified by MH CPP visits into those with 2 or more visits ("ongoing MH CPP care"), those with 1 visit ("consultative MH CPP care"), and those with no visits ("no MH CPP care"). Patient complexity for each condition was defined by medication regimen and service utilization. RESULTS: For schizophrenia, more patients in ongoing MH CPP care were complex than those with no MH CPP care, based on all measures examined: the number of primary medications (15.3% vs 8.1%), inpatient (13.7% vs 9.1%) and outpatient (42.6% vs 29.7%) utilization, and receipt of long-acting injectable antipsychotics (36.7% vs 25.8%) and clozapine (20.5% vs 9.5%). For bipolar disorder, more patients receiving ongoing or consultative MH CPP care were complex than those with no MH CPP care based on the number of primary medications (27.9% vs 30.5% vs 17.7%) and overlapping mood stabilizers (10.1% vs 11.6% vs 6.2%). For MDD, more patients receiving ongoing or consultative MH CPP care were complex based on the number of primary medications (36.8% vs 35.5% vs 29.2%) and augmentation of antidepressants (56.1% vs 54.4% vs 47.0%) than patients without MH CPP care. All comparisons were significant (P < 0.01). CONCLUSION: MH CPPs provide care for complex patients with schizophrenia, bipolar disorder, and MDD in VA.

BACKGROUND: Warfarin is effective in preventing thromboembolic events, but concerns exist regarding its use in patients with substance abuse. OBJECTIVE: Identify which patients with substance abuse who receive warfarin are at risk for poor outcomes. DESIGN: Retrospective cohort study. Diagnostic codes, lab values, and other factors were examined to identify risk of adverse outcomes. PATIENTS: Veterans AffaiRs Study to Improve Anticoagulation (VARIA) database of 103,897 patients receiving warfarin across 100 sites. MAIN MEASURES: Outcomes included percent time in therapeutic range (TTR), a measure of anticoagulation control, and major hemorrhagic events by ICD-9 codes. RESULTS: Nonusers had a higher mean TTR (62 %) than those abusing alcohol (53 %), drugs (50 %), or both (44 %, p < 0.001). Among alcohol abusers, an increasing ratio of the serum hepatic transaminases aspartate aminotransferase/alanine aminotransferase (AST:ALT) correlated with inferior anticoagulation control; normal AST:ALT ≤ 1.5 predicted relatively modest decline in TTR (54 %, p < 0.001), while elevated ratios (AST:ALT 1.50-2.0 and > 2.0) predicted progressively poorer anticoagulation control (49 % and 44 %, p < 0.001 compared to nonusers). Age-adjusted hazard ratio for major hemorrhage was 1.93 in drug and 1.37 in alcohol abuse (p < 0.001 compared to nonusers), and remained significant after also controlling for anticoagulation control and other bleeding risk factors (1.69 p < 0.001 and 1.22 p = 0.003). Among alcohol abusers, elevated AST:ALT >2.0 corresponded to more than three times the hemorrhages (HR 3.02, p < 0.001 compared to nonusers), while a normal ratio AST:ALT ≤ 1.5 predicted a rate similar to nonusers (HR 1.19, p < 0.05). CONCLUSIONS: Anticoagulation control is particularly poor in patients with substance abuse. Major hemorrhages are more common in both alcohol and drug users. Among alcohol abusers, the ratio of AST/ALT holds promise for identifying those at highest risk for adverse events.

OBJECTIVE: We examined patient attitudes and beliefs and provider perspectives on patients' attitudes and beliefs towards testosterone therapy in Veterans Affairs (VA). METHODS: We used a thematic analysis approach to understand variation in patient attitudes and beliefs towards testosterone at six VA sites with high and low levels of testosterone prescribing in VA. Semi-structured phone interviews with 18 patients and 22 providers at these sites were transcribed and coded using a priori theoretical constructs and emergent themes. A cross-case matrix of coded data was used to evaluate themes related to patient-level factors. RESULTS: Patients' beliefs toward testosterone did not differ across sites. Patients, not providers, generally initiated conversations about testosterone. We identified five key domains related to patient beliefs and provider perceived patient beliefs towards testosterone: reasons for initiating testosterone, patient information sources and expectations about testosterone, receptivity towards discontinuation of testosterone, patient/provider engagement in information sharing, and self-advocacy by the patients in decision-making. CONCLUSIONS: Patient factors play an important role in testosterone prescribing decisions. PRACTICE IMPLICATIONS: By considering these patient factors, providers can potentially help create a partnership with patients and foster shared decision-making for testosterone and other, similar medications.

OBJECTIVE: Evictions are important social and behavioral determinants of health. Evictions are associated with a cascade of negative events that can lead to unemployment, housing insecurity/homelessness, long-term poverty, and mental health problems. In this study, we developed a natural language processing system to automatically detect eviction status from electronic health record (EHR) notes. MATERIALS AND METHODS: We first defined eviction status (eviction presence and eviction period) and then annotated eviction status in 5000 EHR notes from the Veterans Health Administration (VHA). We developed a novel model, KIRESH, that has shown to substantially outperform other state-of-the-art models such as fine-tuning pretrained language models like BioBERT and Bio_ClinicalBERT. Moreover, we designed a novel prompt to further improve the model performance by using the intrinsic connection between the 2 subtasks of eviction presence and period prediction. Finally, we used the Temperature Scaling-based Calibration on our KIRESH-Prompt method to avoid overconfidence issues arising from the imbalance dataset. RESULTS: KIRESH-Prompt substantially outperformed strong baseline models including fine-tuning the Bio_ClinicalBERT model to achieve 0.74672 MCC, 0.71153 Macro-F1, and 0.83396 Micro-F1 in predicting eviction period and 0.66827 MCC, 0.62734 Macro-F1, and 0.7863 Micro-F1 in predicting eviction presence. We also conducted additional experiments on a benchmark social determinants of health (SBDH) dataset to demonstrate the generalizability of our methods. CONCLUSION AND FUTURE WORK: KIRESH-Prompt has substantially improved eviction status classification. We plan to deploy KIRESH-Prompt to the VHA EHRs as an eviction surveillance system to help address the US Veterans' housing insecurity.

Purpose: Health disparities in transgender and gender diverse (TGD) veterans compared with cisgender veterans have been documented. However, there is a paucity of literature focused on older TGD veterans. We assessed health conditions and social stressors in older TGD veterans compared with matched cisgender veterans. Methods: Using gender identity disorder diagnosis codes, we identified 1244 TGD veterans (65+ years of age) receiving care in the Veterans Health Administration (VHA) from 2006 to 2018. These TGD veterans were then matched to 3732 cisgender veterans based on age, VHA site, and date of care in VHA. Results: In adjusted models, TGD veterans compared with cisgender veterans were less likely to have alcohol use disorder (adjusted odds ratio [AOR; 95% confidence interval]: [0.70; 0.58-0.85]), drug use disorder (0.59; 0.47-0.74), tobacco use (0.75; 0.65-0.86), and anxiety (0.74; 0.62-0.90). However, compared with cisgender veterans, TGD veterans were more likely to experience depression (1.63; 1.39-1.93), Alzheimer's disease (8.95; 4.25-18.83), cancer (1.83; 1.56-2.14), violence (1.82; 1.14-2.91), social/familial problems (2.45; 1.99-3.02), lack of access to care/transportation (2.23; 1.48-3.37), and military sexual trauma (2.59; 1.93-3.46). Furthermore, compared with cisgender veterans, TGD veterans were more likely to have documentation of a higher count of social stressors: 1 or more stressors (1.64; 1.38-1.95) and 2 or more stressors (1.22; 1.01-1.49). Conclusion: Despite significant disparities in social stressors and health conditions compared with cisgender veterans, TGD veterans had a lower likelihood of substance use and anxiety. Interventions are needed to mitigate social stressors and improve health among the older TGD veteran population.

Importance: Social determinants of health (SDOHs) are known to be associated with increased risk of suicidal behaviors, but few studies use SDOHs from unstructured electronic health record notes. Objective: To investigate associations between veterans' death by suicide and recent SDOHs, identified using structured and unstructured data. Design, Setting, and Participants: This nested case-control study included veterans who received care under the US Veterans Health Administration from October 1, 2010, to September 30, 2015. A natural language processing (NLP) system was developed to extract SDOHs from unstructured clinical notes. Structured data yielded 6 SDOHs (ie, social or familial problems, employment or financial problems, housing instability, legal problems, violence, and nonspecific psychosocial needs), NLP on unstructured data yielded 8 SDOHs (social isolation, job or financial insecurity, housing instability, legal problems, barriers to care, violence, transition of care, and food insecurity), and combining them yielded 9 SDOHs. Data were analyzed in May 2022. Exposures: Occurrence of SDOHs over a maximum span of 2 years compared with no occurrence of SDOH. Main Outcomes and Measures: Cases of suicide death were matched with 4 controls on birth year, cohort entry date, sex, and duration of follow-up. Suicide was ascertained by National Death Index, and patients were followed up for up to 2 years after cohort entry with a study end date of September 30, 2015. Adjusted odds ratios (aORs) and 95% CIs were estimated using conditional logistic regression. Results: Of 6â¯122â¯785 veterans, 8821 committed suicide during 23â¯725â¯382 person-years of follow-up (incidence rate 37.18 per 100â¯000 person-years). These 8821 veterans were matched with 35â¯284 control participants. The cohort was mostly male (42â¯540 [96.45%]) and White (34â¯930 [79.20%]), with 6227 (14.12%) Black veterans. The mean (SD) age was 58.64 (17.41) years. Across the 5 common SDOHs, NLP-extracted SDOH, on average, retained 49.92% of structured SDOHs and covered 80.03% of all SDOH occurrences. SDOHs, obtained by structured data and/or NLP, were significantly associated with increased risk of suicide. The 3 SDOHs with the largest effect sizes were legal problems (aOR, 2.66; 95% CI, 2.46-2.89), violence (aOR, 2.12; 95% CI, 1.98-2.27), and nonspecific psychosocial needs (aOR, 2.07; 95% CI, 1.92-2.23), when obtained by combining structured data and NLP. Conclusions and Relevance: In this study, NLP-extracted SDOHs, with and without structured SDOHs, were associated with increased risk of suicide among veterans, suggesting the potential utility of NLP in public health studies.

Context: Accurate measures to assess appropriateness of testosterone prescribing are needed to improve prescribing practices. Objective: This work aimed to develop and validate quality measures around the initiation and monitoring of testosterone prescribing. Methods: This retrospective cohort study comprised a national cohort of male patients receiving care in the Veterans Health Administration who initiated testosterone during January or February 2020. Using laboratory data and diagnostic codes, we developed 9 initiation and 7 monitoring measures. These were based on the current Endocrine Society guidelines supplemented by expert opinion and prior work. We chose measures that could be operationalized using national VA electronic health record (EHR) data. We assessed criterion validity for these 16 measures by manual review of 142 charts. Main outcome measures included positive and negative predictive values (PPVs, NPVs), overall accuracy (OA), and Matthews Correlation Coefficients (MCCs). Results: We found high PPVs (>78%), NPVs (>98%), OA (≥94%), and MCCs (>0.85) for the 10 measures based on laboratory data (5 initiation and 5 monitoring). For the 6 measures relying on diagnostic codes, we similarly found high NPVs (100%) and OAs (≥98%). However, PPVs for measures of acute conditions occurring before testosterone initiation (ie, acute myocardial infarction or stroke) or new conditions occurring after initiation (ie, prostate or breast cancer) PPVs were much lower (0% to 50%) due to few or no cases. Conclusion: We developed several valid EHR-based quality measures for assessing testosterone-prescribing practices. Deployment of these measures in health care systems can facilitate identification of quality gaps in testosterone-prescribing and improve care of men with hypogonadism.
