Reasons for contacting a crisis line and the initiation of emergency dispatches.

OBJECTIVE: To better understand processes of mental health crisis line utilization by examining associations between reasons for contacting a crisis line with the initiation of emergency dispatches (i.e., activation of 911 or local emergency services) in a national sample. METHODS: Contacts (i.e., calls, texts, email, and chats) to the Veterans Crisis Line (VCL) across 2017-2020 were used to examine associations among stated reasons for the contact and the use of an emergency dispatch. Hierarchical logistic regression models were used to determine the odds of an emergency dispatch by reason for the contact. RESULTS: Suicidal thoughts/crisis were present in 61.5% of contacts that ended in emergency dispatches and were associated with the largest adjusted odds of a dispatch, (Adjusted Odds Ratio [AOR] [95% CI] = 9.34 [9.21, 9.48]), followed by homicidal thoughts/crisis (AOR [95% CI] = 3.84 [3.73, 3.95]), and third-party concerns (AOR [95% CI] = 2.42 [2.37, 2.47]). Substance use/ addiction (AOR [95% CI] = 2.14 [2.10, 2.18]), abuse and violence (AOR [95% CI] = 1.89 [1.82, 1.96]), and physical health (AOR [95% CI] = 1.87 [1.84, 1.91]) were also associated with increased odds of a dispatch. CONCLUSIONS: Emergency dispatches are primarily used in response to imminent suicide risk but are also used in other potentially violent or lethal circumstances such as homicides, violence or abuse, and other crises. These findings highlight the role that crisis lines play in emergency service delivery, and the need to better understand how they are utilized under real world circumstances.

What Happens Next? Maintenance of Gains After Discharge From VA Residential PTSD Treatment.

ABSTRACT: Residential posttraumatic stress disorder (PTSD) treatment in the Department of Veterans Affairs is helpful for many Veterans, yet the majority experience symptom rebound after discharge. This study examined a national cohort of Veterans (n = 1872) who completed VA residential PTSD treatment and identified factors associated with maintenance of gains from discharge to 4-month follow-up. We generated three logistic regression models based on response profiles during residential treatment. In the "marginal responders" group, 1-3 "booster" sessions of PTSD treatment were associated with decreased odds of maintenance of gains (odds ratio [OR], 0.42), whereas in the "clinically significant responders" group, these sessions were associated with increased odds of maintenance of gains (OR, 2.89). Greater pain severity was associated with decreased odds of maintenance of gains in the "clinically significant responder" group (OR, 0.90). Results demonstrate several avenues for intervention including targeting pain severity and matching aftercare psychotherapy to Veteran residential treatment response.

Feasibility and Acceptability of Prolonged Exposure in Primary Care (PE-PC) for Posttraumatic Stress Disorder in Federally Qualified Health Centers: A Pilot Study.

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder that affects 6% of U.S. adults, yet is treated in only 30% of affected individuals and even fewer low-income individuals. One third of the nation's low-income individuals are treated in Federally Qualified Health Centers (FQHCs). Most of these facilities lack capacity to provide their patients with first-line, evidence-based treatments for PTSD such as Prolonged Exposure (PE). To address this problem, PE has been adapted for use in a primary care setting and demonstrated efficacy in a brief model for military service members (PE in Primary Care: PE-PC). The effectiveness of this treatment in civilian, low-resource settings such as FQHCs is unknown. This pilot study tested the feasibility and acceptability of PE-PC in 30 Michigan FQHC patients. High rates of therapy participation suggest that the intervention was feasible and acceptable. Semi-structured interview data from 10 patients and 5 FQHC providers indicated that the intervention was helpful and filled a critical need for effective PTSD treatment in the FQHC setting. Interviews also elucidated barriers such as transportation, provider training, and time commitment for patients and providers. These findings set the stage for a full-scale randomized controlled trial to test the effectiveness of PE-PC on PTSD symptoms in this low-resource, high-need setting.Trial registry ClinicalTrials.gov Identifier: NCT03711266.

The Prevalence and Incidence of Attention-deficit/Hyperactivity Disorder in the Veterans Health Administration From 2009 to 2016.

BACKGROUND: The prevalence and incidence of attention-deficit/hyperactivity disorder (ADHD) have increased substantially among children and adolescents over the past decade; however, little is known regarding trends in adult populations. OBJECTIVE: The objective of this study was to explore trends in the prevalence, incidence, and correlates of adult ADHD in a national sample of veterans receiving care at Veteran Affairs (VA) hospitals and clinics. RESEARCH DESIGN: A retrospective design was used to examine ADHD diagnosed in all VA primary care (PC) and mental health clinics (MHCs) from fiscal years (FYs) 2009 to 2016. Age-adjusted prevalence and incidence were calculated using direct standardization, and Poisson regressions modeled differences in trends between demographic groups. SUBJECTS: All veterans with VA PC or MHC visits during the observation period. MEASURES: ADHD incidence and prevalence, psychiatric comorbidity, neuropsychological evaluation. RESULTS: An annual average of 5.09 million (range: 4.63-5.42 million) VA patients attended a PC or MHC appointment between FY09 and FY16. During this period, age-adjusted annual prevalence increased 258% from 0.23% to 0.84% and incidence increased 240% from 0.14% to 0.48%. Black veterans and older veterans had the lowest prevalence and incidence across all years. Increases in prevalence and incidence occurred across all demographic subgroups. The proportion of patients who had a neuropsychological evaluation within 6 months before or after a new ADHD diagnosis decreased from 12.6% to 10.8% [χ(1)=16.59, P<0.001]. CONCLUSION: Overall increases and demographic differences in adult veterans diagnosed with ADHD suggest a growing need to establish the reliability of diagnostic practices to ensure appropriate and equitable care.

Associations Between the NIH Toolbox Adult Social Relationship Scales and Suicidal Ideation.

Various measures of social support have been associated with suicidal ideation (SI). However, a brief, consistent, multidimensional approach to social support assessment has not been established. We assessed the NIH Toolbox Adult Social Relationship (ASR) scales and their associations with the Beck Scale for Suicidal Ideation (BSI). Five ASR scales (emotional support, instrumental support, friendship, loneliness, perceived rejection) were used to predict BSI scores among psychiatric inpatients at baseline (N = 79) and at 3-months follow-up (N = 63). Mean BSI scores were 22.2 (SD 8.6) at baseline and 5.7 (SD 6.7) at follow-up. The ASR scales had high internal consistency (Cronbach's α = 0.93-0.96). Emotional support was associated with SI at baseline and 3-month follow-up. Instrumental support, loneliness and perceived rejection were associated with SI at baseline. Friendship was not associated with SI at either time-point. The ASR scales appear promising in differentiating aspects of social support most relevant to SI.

Opioid Prescribing After Opioid-related Inpatient Hospitalizations by Diagnosis: A Cohort Study.

BACKGROUND: Any opioid-related hospitalization is an indicator of opioid-related harm and should ideally trigger carefully monitored decreases in opioid prescribing after inpatient stays in many, if not most, cases. However, past studies on opioid prescribing after hospitalizations have largely been limited to overdose related visits. It is unclear whether prescribing is different for other opioid-related indications such as opioid dependence and abuse and how that may compare with hospitalizations for overdose. OBJECTIVE: To examine opioid-prescribing patterns before and after opioid-related hospitalizations for all opioid-related indications, not limited to overdose. RESEARCH DESIGN: Retrospective cohort analysis of Veterans Health Administration (VHA) administrative claims from 2011 to 2014. SUBJECTS: VHA patients who were hospitalized between fiscal years 2011 and 2014 and had at least 1 prescription opioid medication filled through the VHA pharmacy before their hospitalization. MEASURES: Opioid dispensing trajectories after hospitalization by opioid-related indication (ie, opioid dependence and/or abuse vs. overdose) compared with prescribing patterns for non-opioid-related hospitalizations. RESULTS: Overall, opioid dosage dropped significantly (66% for dependence/abuse, 42% for overdose, and 3% for nonopioid diagnoses; P<0.001) across all 3 categories when comparing dose 57-63 days after admission to 57-63 days before hospitalization. However, 47% of the patients remained on the same dose or increased their opioid dose at 60 days after an opioid-related hospitalization. After adjusting for covariates, patients with a primary diagnosis of dependence/abuse had higher odds of having their dose discontinued compared with those with overdose: odds ratio (OR) 2.17 (1.19-3.96). Patients with admissions for opioid dependence and/or abuse had a statistically significant higher prevalence of depression, posttraumatic stress disorder, anxiety, and substance use disorders compared with those with an opioid overdose hospitalization. CONCLUSIONS: Opioid prescribing and patient risk factors before and after opioid-related hospitalizations vary by indication for hospitalization. To reduce costs and morbidity associated with opioid-related hospitalizations, opioid deintensification efforts need to be tailored to indication for hospitalization.

Longitudinal patterns of PTSD symptom classes among US National Guard service members during reintegration.

PURPOSE: The purpose of this study was to identify posttraumatic stress disorder (PTSD) symptom groups and assess their longitudinal progression during their first year of reintegration among United States (US) National Guard (NG) service members. METHODS: A cohort of NG service members (n = 886) completed surveys at 6 and 12 months following their return from deployment to Iraq or Afghanistan. Latent class analysis (LCA) and latent transition analysis (LTA) were used to empirically derive groups based on their PTSD symptoms and examine their longitudinal course, respectively. RESULTS: The best fitting model at both assessments was the four-class model, comprising an asymptomatic class (6 months = 54%; 12 months = 55%), a mild symptom class with elevated hyperarousal symptoms (6 months = 22%; 12 months = 17%), a moderate symptom class (6 months = 15%; 12 months = 15%), and a severe symptom class (6 months = 10%; 12 months = 13%). Based on LTA, stability of class membership at the two assessments was 0.797 for the asymptomatic class, 0.453 for the mild class, 0.560 for the moderate class, and 0.580 for the severe class. Estimated transition probabilities were greater with respect to transitioning to less severe, rather than more severe, classes over time. CONCLUSIONS: The four latent PTSD classes were distinguished primarily by severity; however, the mild symptom class was characterized by higher levels of hyperarousal than other symptoms. Although the absolute number of individuals within classes remained fairly constant between 6 and 12 months, there was movement between severity classes. Most NG service members without symptoms continued to do well during the first year, with only an estimated 7% moving to the moderate or severe class.

Documentation of Evidence-Based Psychotherapy and Care Quality for PTSD in the Department of Veterans Affairs.

This study measured the prevalence of evidence-based psychotherapy (EBP) templated notes in VA and tested the hypothesis that template use would be associated with care quality for posttraumatic stress disorder (PTSD). Across 130 facilities, an average of 3.6% of patients with a PTSD diagnosis received at least one EBP template in 2015. Among patients receiving psychotherapy for PTSD, an average of 8.5% received an EBP template. In adjusted models, facility-level EBP template use was associated with a greater proportion of PTSD-diagnosed patients treated in specialty clinics, greater facility-level rates of diagnostic assessment, and greater facility-level rates of psychotherapy adequacy.

Predictors of PTSD Symptom Change Among Outpatients in the U.S. Department of Veterans Affairs Health Care System.

Although the U.S. Department of Veterans Affairs (VA) has prioritized care for posttraumatic stress disorder (PTSD), many patients with PTSD remain symptomatic. Patterns of PTSD symptom change are not well understood. Thus, the current study was designed to categorize and investigate potential predictors of symptom trajectories in patients with PTSD. The sample comprised 2,237 VA patients who were diagnosed with PTSD in 2013 and completed at least 4 PTSD Checklist (PCL) assessments over 12 weeks. Latent trajectory analysis was used to identify latent classes of patients based on PCL scores. Based on model fit indices, 3 trajectories were identified. Compared to patients in the mild-improving trajectory (21.9%), those in the severe-stable trajectory (34.3%) were more likely to be male, relative risk ratio (RRR) = 1.48, 95% CI [1.08, 2.02]; non-White, RRR = 1.77, 95% CI [1.33, 2.35]; Hispanic, RRR = 2.07, 95% CI [1.40, 3.04]; and have comorbid depression, RRR = 1.58, 95% CI [1.25, 1.99]. Compared to patients in the moderate-improving trajectory (43.8%), those in the severe-stable trajectory were more likely to have sleep disorders, RRR = 1.25, 95% CI [1.01, 1.55]. Our findings suggest that male veterans, minority veterans, and veterans with certain comorbid conditions may be less likely to achieve improved PTSD symptoms. Targeted efforts are needed to improve outcomes for PTSD patients on nonremitting trajectories and to improve the consistency of PTSD assessment across the VA health care system.

Pilot study of enhanced social support with automated telephone monitoring after psychiatric hospitalization for depression.

BACKGROUND: Following discharge, patients hospitalized for depression are at high risk for poor retention in outpatient care and adverse outcomes. AIMS: Pilot tests a post-hospital monitoring and enhanced support program for depression. METHOD: 48 patients at a Veterans Affairs Medical Center discharged following a depression-related inpatient stay received weekly visits or phone calls for 6 months from their choice of either a family member/friend (n = 19) or a certified peer support specialist (n = 29). Participants also completed weekly automated telephone monitoring calls assessing depressive symptoms and antidepressant medication adherence. RESULTS: Over 90% of participants were more satisfied with their care due to the service. The mean change from baseline to 6 months in depression symptoms was -7.9 (p < 0.05) according to the Patient Health Questionnaire and -11.2 (p < 0.05) according to the Beck Depression Inventory-II for those supported by a family member/friend, whereas those supported by a peer specialist had mean changes of -3.5 (p < 0.05) and -1.7 (p > 0.10), respectively. CONCLUSIONS: Increased contact with a chosen support person coupled with automated telephone monitoring after psychiatric hospitalization is an acceptable service for patients with depression. Those who received the service, and particularly those supported by a family member/friend, experienced reductions in symptoms of depression.

A Detailed Exploration Into the Association of Prescribed Opioid Dosage and Overdose Deaths Among Patients With Chronic Pain.

BACKGROUND: High opioid dosage has been associated with overdose, and clinical guidelines have cautioned against escalating dosages above 100 morphine-equivalent mg (MEM) based on the potential harm and the absence of evidence of benefit from high dosages. However, this 100 MEM threshold was chosen somewhat arbitrarily. OBJECTIVE: To examine the association of prescribed opioid dosage as a continuous measure in relation to risk of unintentional opioid overdose to identify the range of dosages associated with risk of overdose at a detailed level. METHODS: In this nested case-control study with risk-set sampling of controls, cases (opioid overdose decedents) and controls were identified from a population of patients of the Veterans Health Administration who were prescribed opioids and who have a chronic pain diagnosis. Unintentional fatal opioid analgesic overdose was measured from National Death Index records and prescribed opioid dosage from pharmacy records. RESULTS: The average prescribed opioid dosage was higher (P<0.001) for cases (mean=98.1 MEM, SD=112.7; median=60, interquartile range, 30-120), than controls (mean=47.7 MEM, SD=65.2; median=25, interquartile range, 15-45). In a ROC analysis, dosage was a moderately good "predictor" of opioid overdose death, indicating that, on average, overdose cases had a prescribed opioid dosage higher than 71% of controls. CONCLUSIONS: A clear cut-point in opioid dosage to distinguish between overdose cases and controls was not found. However, lowering the recommended dosage threshold below the 100 MEM used in many recent guidelines would affect proportionately few patients not at risk for overdose while potentially benefitting many of those at risk for overdose.

Self-Determination Theory and Outpatient Follow-Up After Psychiatric Hospitalization.

The objective of this study was to assess whether the constructs of self-determination theory-autonomy, competence, and relatedness-are associated with adherence to outpatient follow-up appointments after psychiatric hospitalization. 242 individuals discharged from inpatient psychiatric treatment within the Veterans Health Administration completed surveys assessing self-determination theory constructs as well as measures of depression and barriers to treatment. Medical records were used to count the number of mental health visits and no-shows in the 14 weeks following discharge. Logistic regression models assessed the association between survey items assessing theory constructs and attendance at mental healthcare visits. In multivariate models, none of the self-determination theory factors predicted outpatient follow-up attendance. The constructs of self-determination theory as measured by a single self-report survey may not reliably predict adherence to post-hospital care. Need factors such as depression may be more strongly predictive of treatment adherence.

Social networks, mental health problems, and mental health service utilization in OEF/OIF National Guard veterans.

PURPOSE: Low social support and small social network size have been associated with a variety of negative mental health outcomes, while their impact on mental health services use is less clear. To date, few studies have examined these associations in National Guard service members, where frequency of mental health problems is high, social support may come from military as well as other sources, and services use may be suboptimal. METHODS: Surveys were administered to 1448 recently returned National Guard members. Multivariable regression models assessed the associations between social support characteristics, probable mental health conditions, and service utilization. RESULTS: In bivariate analyses, large social network size, high social network diversity, high perceived social support, and high military unit support were each associated with lower likelihood of having a probable mental health condition (p < .001). In adjusted analyses, high perceived social support (OR .90, CI .88-.92) and high unit support (OR .96, CI .94-.97) continued to be significantly associated with lower likelihood of mental health conditions. Two social support measures were associated with lower likelihood of receiving mental health services in bivariate analyses, but were not significant in adjusted models. CONCLUSIONS: General social support and military-specific support were robustly associated with reduced mental health symptoms in National Guard members. Policy makers, military leaders, and clinicians should attend to service members' level of support from both the community and their units and continue efforts to bolster these supports. Other strategies, such as focused outreach, may be needed to bring National Guard members with need into mental health care.

A global logrank test for adaptive treatment strategies based on observational studies.

In studying adaptive treatment strategies, a natural question that is of paramount interest is whether there is any significant difference among all possible treatment strategies. When the outcome variable of interest is time-to-event, we propose an inverse probability weighted logrank test for testing the equivalence of a fixed set of pre-specified adaptive treatment strategies based on data from an observational study. The weights take into account both the possible selection bias in an observational study and the fact that the same subject may be consistent with more than one treatment strategy. The asymptotic distribution of the weighted logrank statistic under the null hypothesis is obtained. We show that, in an observational study where the treatment selection probabilities need to be estimated, the estimation of these probabilities does not have an effect on the asymptotic distribution of the weighted logrank statistic, as long as the estimation of the parameters in the models for these probabilities is n-consistent. Finite sample performance of the test is assessed via a simulation study. We also show in the simulation that the test can be pretty robust to misspecification of the models for the probabilities of treatment selection. The method is applied to analyze data on antidepressant adherence time from an observational database maintained at the Department of Veterans Affairs' Serious Mental Illness Treatment Research and Evaluation Center.

Reported barriers to mental health care in three samples of U.S. Army National Guard soldiers at three time points.

The military community and its partners have made vigorous efforts to address treatment barriers and increase appropriate mental health services use among returning National Guard soldiers. We assessed whether there were differences in reports of treatment barriers in 3 categories (stigma, logistics, or negative beliefs about treatment) in sequential cross-sectional samples of U.S. soldiers from a Midwestern Army National Guard Organization who were returning from overseas deployments. Data were collected during 3 time periods: September 2007-August 2008 (n = 333), March 2009-March 2010 (n = 884), and August 2011-August 2012 (n = 737). In analyses using discretized time periods and in trend analyses, the percentages of soldiers endorsing negative beliefs about treatment declined significantly across the 3 sequential samples (19.1%, 13.9%, and 11.1%). The percentages endorsing stigma barriers (37.8%, 35.2%, 31.8%) decreased significantly only in trend analyses. Within the stigma category, endorsement of individual barriers regarding negative reactions to a soldier seeking treatment declined, but barriers related to concerns about career advancement did not. Negative treatment beliefs were associated with reduced services use (OR = 0.57; 95% CI [0.33, 0.97]).

Psychiatric diagnoses, somatic disorders, and emergency dispatches among individuals who used a national suicide crisis line.

Crisis line responders initiate emergency dispatches by activating 911 or other local emergency services when individuals are determined to be at imminent risk for undesired outcomes. This study examined the association of characteristics, psychiatric diagnoses, and somatic symptoms with emergency dispatches in a national sample. Veterans Crisis Line data were used to identify contacts (i.e., calls, texts, chats, emails) that were linked with medical records and had a medical encounter in the year prior to contact. Hierarchical logistic regression clustered by responders was used to identify the association among demographics, psychiatric diagnoses, and somatic disorders, and emergency dispatches. Analyses examined 247,340 contacts from 2017 to 2020, with 27,005 (10.9%) emergency dispatches. Odds of an emergency dispatch increased with each diagnosis (three diagnoses Adjusted Odds Ratio [AOR] (95% CI) = 1.88 [1.81,1.95]). Odds were highest among individuals with substance use disorders (SUD) (alcohol AOR (95% CI) = 1.85 [1.80,1.91]; drugs AOR (95% CI) = 1.63 [1.58, 1.68]), which may be a result of intoxication or overdose during contact, requiring further research. Having more psychiatric and somatic conditions was associated with greater odds of an emergency dispatch, indicating that comorbidity contributed to the need for acute care.

Clinical Outcomes of Intravenous Ketamine Treatment for Depression in the VA Health System.

Objective/Background: Intravenous (IV) ketamine is effective for reducing symptoms of major depressive disorder in short-term clinical trials; this study characterized clinical outcomes of repeated infusions in routine clinical practice and the frequency and number of infusions used to sustain symptom improvement.Methods: Records of IV ketamine infusions for depression and associated Patient Health Questionnaire-9 (PHQ-9) scores were identified from Veterans Health Administration (VA) electronic medical records for patients treated in Fiscal Year 2020 and up to 12 months following the date of their first infusion.Results: Sample patients (n = 215) had a mean baseline PHQ-9 score of 18.6 and a mean of 2.1 antidepressant medication trials in the past year and 6.1 antidepressant trials in the 20 years prior to their first ketamine infusion. Frequency of infusions decreased from every 5 days to every 3-4 weeks over the first 5 months of infusions, with a mean of 18 total infusions over 12 months. After 6 weeks of treatment, 26% had a 50% improvement in PHQ-9 score (response) and 15% had PHQ-9 score ≤ 5 (remission). These improvements were similar at 12 and 26 weeks. No demographic characteristics or comorbid diagnoses were associated with 6-week PHQ-9 scores.Conclusions: While only a minority of patients treated with IV ketamine for depression experienced response or remission, symptom improvements achieved within the first 6 weeks were sustained over at least 6 months with decreasing infusion frequency. Further study is needed to determine optimal infusion frequency and potential for adverse effects with repeated ketamine infusions for depression.

Outcomes of Acceptance and Commitment Therapy for depression and predictors of treatment response in Veterans Health Administration patients.

BACKGROUND: Acceptance and Commitment Therapy for depression (ACT-D) is a promising depression treatment which has not been evaluated on a large scale within VA. This study aimed to evaluate ACT-D's effectiveness in a national, treatment-seeking sample of Veterans. METHODS: The sample comprised 831 Veterans who received a primary depression diagnosis and received at least two sessions of ACT-D during fiscal years 2015-2020. We used GLM to measure predictors of symptom change, treatment response (50 % reduction in PHQ-9 and AAQ-II scores), subthreshold depression symptoms (PHQ-9 < 10; AAQ-II < 27), and treatment completion. RESULTS: Veterans experienced an average reduction of 3.39 points on the PHQ-9 (Cohen's d = 0.56) and 3.76 points on the AAQ-II (Cohen's d = 0.43). On the PHQ-9, 40 % achieved subthreshold depression symptoms. On the AAQ-II, 36 % of Veterans achieved subthreshold psychological inflexibility scores. Service-connected disability rating for depression and higher levels of medical comorbidity were both related to lower levels of overall depression symptom change and treatment response. Substance use disorder and bipolar/psychosis diagnoses were associated with greater reductions in psychological inflexibility. LIMITATIONS: This is an observational study without a control group, so we were unable to compare the effectiveness of ACT-D to other usual care for depression. We were also unable to assess variables that can influence treatment success, such as therapist fidelity and patient engagement. CONCLUSIONS: ACT-D achieved similar improvements in depression as reported in controlled trials. Adaptations to ACT-D may be needed to improve outcomes for Veterans with depression and comorbid PTSD.

Analysis of veterans crisis line data: Temporal factors associated with the initiation of emergency dispatches.

PURPOSE: To identify temporal patterns of emergency dispatches as initiated by Veteran Crisis Line (VCL) responders and among moderate- and high-risk contacts. METHODS: Incidence rate ratios (IRRs) were used to examine the incidence of emergency dispatches among all 1,437,543 VCL contacts across 2019-2020. RESULTS: Emergency dispatches were initiated in 57,077 (4.0%) contacts. IRRs were elevated during Labor Day, IRR (95% CI) = 1.33 (1.15-1.54), and Independence Day, IRR (95% CI) = 1.22 (1.05-1.43), weekends, Saturdays, IRR (95% CI) = 1.04 (1.01-1.08), Sunday (reference), and 6 pm to 11:59 pm, IRR (95% CI) = 1.06 (1.04-1.09). IRRs for moderate- and high-risk contacts were higher on Memorial Day, IRR (95% CI) = 1.16 (1.00-1.33), Sunday (reference), and 6 pm to 11:59 pm (reference). CONCLUSIONS: The initiation of emergency dispatches fluctuates over time and were highest during Labor Day and Independence Day, weekends, and evenings. Moderate- and high-risk contact also fluctuate over time and were highest on Memorial Day, Sundays, and midnight to 5:59 am. VCL policy makers can use knowledge of temporal fluctuations to allocate public health resources for increased efficiency and greatest impact; however, additional research on temporal stability and generalizability is needed.

Guideline-concordant use of cognitive behavioral therapy for insomnia in the Veterans Health Administration.

OBJECTIVE: To characterize guideline-concordant use of cognitive behavioral therapy for insomnia vs. sleep medications among Veterans Health Administration patients. METHODS: Cognitive behavioral therapy for insomnia was identified from the text of psychotherapy notes within the Veterans Health Administration's electronic medical record. Patients that received first-line cognitive behavioral therapy for insomnia (ie, no prior insomnia treatment) were compared to those who first received a sleep medication in fiscal year 2021. RESULTS: Among 5,519,016 patients, first-line cognitive behavioral therapy for insomnia was received by 9313 (0.2%) whereas 225,618 (4.1%) were newly prescribed a sleep medication without prior cognitive behavioral therapy for insomnia. Patients over 60 years old and those with substance use disorders were less likely to receive first-line cognitive behavioral therapy for insomnia compared to other patients. CONCLUSIONS: Adherence to practice guidelines to provide cognitive behavioral therapy for insomnia as first-line treatment for insomnia disorder remains a challenge, highlighting the need to better integrate effective implementation strategies within therapist training programs. Targeted strategies may be needed for older patients or those with substance use disorders.
