Assessing survival in non-small cell lung cancer brain metastases after stereotactic radiosurgery: before and after the start of the targetable mutation era.

PURPOSE: Targeted treatment options for non-small cell lung cancer (NSCLC) brain metastases (BMs) may be combined with stereotactic radiosurgery (SRS) to optimize survival. We assessed patient outcomes after SRS for NSCLC BMs, identifying survival trajectories associated with targetable mutations. METHODS: In this retrospective time-dependent analysis, we analyzed median overall survival of patients who received ≥ 1 SRS courses for BM from NSCLC from 2001 to 2021. We compared survival of patients with and without targetable mutations based on clinical variables and treatment. RESULTS: Among the 213 patients included, 87 (40.8%) had targetable mutations-primarily EGFR (22.5%)-and 126 (59.2%) did not. Patients with targetable mutations were more often female (63.2%, p <.001) and nonsmokers (58.6%, p <.001); had higher initial lung-molGPA (2.0 vs. 1.5, p <.001) and lower cumulative tumor volume (3.7 vs. 10.6 cm3, p <.001); and received more concurrent (55.2% vs. 36.5%, p =.007) and total (median 3 vs. 2, p <.001) systemic therapies. These patients had lower mortality rates (74.7% vs. 91.3%, p <.001) and risk (HR 0.298 [95%CI 0.190-0.469], p <.001) and longer median overall survival (20.2 vs. 7.4 months, p <.001), including survival ≥ 3 years (p =.001). Survival was best predicted by SRS with tumor resection in patients with non-targetable mutations (HR 0.491 [95%CI 0.318-757], p =.001) and by systemic therapy with SRS for those with targetable mutations (HR 0.124 [95%CI 0.013-1.153], p =.067). CONCLUSION: The presence of targetable mutations enhances survival in patients receiving SRS for NSCLC BM, particularly when used with systemic therapies. Survival for patients without targetable mutations was longest with SRS and surgical resection. These results inform best practices for managing patients with NSCLC BM based on driver mutation status.

Evaluation of methamphetamine assist packs: As-needed antipsychotics for self-management of methamphetamine-associated psychiatric toxicity.

BACKGROUND: Methamphetamine frequently causes substance-induced psychosis and related symptoms. There are currently no interventions to prevent or assist in self-management of these symptoms. METHODS: We evaluated a program providing "Methamphetamine Assist Packs" to patients who were seen in a psychiatric emergency services program for methamphetamine-induced psychosis. Methamphetamine Assist Packs included a small number of tablets of an antipsychotic medication (olanzapine), administration instructions, and referral information. We reviewed medical charts of patients who received Methamphetamine Assist Packs from January 2022 through May 2023 for sociodemographic and emergency visit characteristics. We assessed the changes between the number of psychiatric emergency visits before and after Methamphetamine Assist Pack receipt at two, six, and 12 months using generalized estimating equations. RESULTS: Ninety-two patients received a Methamphetamine Assist Pack, with a mean age of 40 years; 79 % were male and 49 % Black/African American; 77 % experienced housing instability or homelessness. The most common symptoms were suicidal ideation (54 %), paranoia or delusions (45 %), and hallucinations (40 %); 55 % were on involuntary psychiatric hold, 38 % required medications for agitation, and 18 % required seclusion or physical restraints. The rate of psychiatric emergency visits after Methamphetamine Assist Pack receipt was 0.68 and 0.87 times the rate prior to receipt at two and six months, respectively (p < 0.001). There was no difference at 12 months. CONCLUSIONS: Methamphetamine Assist Packs were associated with fewer psychiatric emergency visits for six months after receipt, and represent a promising intervention to address acute psychiatric toxicity from methamphetamine in need of further research.

Mobile Crisis Teams' Implementation in the Context of new Medicaid Funding Opportunities: Results from a National Survey.

This cross-sectional survey study describes characteristics of mobile crisis teams (MCTs) in the United States. Mobile crisis teams (MCTs) are increasingly recognized as essential responders to help those experiencing mental health crises get urgent and appropriate care. Recent enhanced federal funding is designed to promote adoption of MCTs, but little is known about their current structure and function and whether teams meet new Medicaid rules governing their utilization. Survey participants (N = 554) are a convenience sample of MCT representatives recruited through professional organizations, listservs, and individual email contacts from October 2021 - May 2022. Respondents most frequently identified themselves as MCT program director/manager (N = 237, 43%). 63% (N = 246) of respondents reported billing insurance for services provided (including Medicaid), while 25% (N = 98) rely on state or county general funds only. Nearly all respondents (N = 390, 98%) reported including behavioral health clinicians on their teams, and 71% (N = 281) reported operating on a 24/7 basis, both of which are required by Medicaid's enhanced reimbursement. Just over half of respondents (N = 191, 52%) reported being staffed with 11 or more FTE staff members, our estimated number required for adequate 2-person coverage on a 24/7 basis. MCTs are a popular policy initiative to reduce reliance on law enforcement to handle mental health emergencies, and enhanced federal funding is likely to expand their utilization. Federal rule makers have a role in establishing guidelines for best practices in staffing, billing, and outcomes tracking, and can help ensure that stable financing is available to improve stability in service delivery.

Impact of regional differences and neighborhood socioeconomic deprivation on the outcomes of patients with lower extremity wounds evaluated by a limb-preservation service.

OBJECTIVE: Management of lower extremity (LE) wounds has evolved with the establishment of specialized limb preservation services. Although clinical factors contribute to limb outcomes, socioeconomic status and community factors also influence the risk for limb loss. The Distressed Community Index (DCI) score is a validated index of social deprivation created to provide an objective measure of economic well-being in United States communities. Few studies have examined the influence of geographic deprivation on outcomes in patients with LE wounds. We examined relationships between socioeconomic deprivation and outcomes of inpatients evaluated by a dedicated limb preservation service (Functional Limb Extremity Service [FLEX]). METHODS: Inpatients referred to FLEX over a 5-year period were included. Wound, Ischemia, foot Infection (WIfI) staging was collected. DCI scores were determined using seven indices based on ZIP Code. Outcomes included any minor or major amputations, any endovascular or open LE revascularization, or wound care procedures. Disease etiology, demographic, and anthropometric data were collected. Associations between neighborhood deprivation and limb-specific outcomes were evaluated in models for the DCI and each of its components separately. RESULTS: A total of 677 patients were included. Thirty-eight percent were female, with a mean age of 64 years. Sixty percent had WIfI stage 3 or 4 risk of amputation, and 43% had WIfI stage 3 or 4 risk of revascularization. Mean ankle-brachial index and toe pressure were 0.96 (standard deviation [SD], 0.43) and 80 (SD, 57) mmHg. Thirty-five percent were non-White. Amputation was performed in 31% of patients, whereas 17% underwent revascularization. The mean distress score was 64 (SD, 24). Mean DCI scores did not differ across WIfI scores. Likewise, overall DCI distress score was not related to any of the outcomes in univariable or multivariable linear regression models. In univariable linear regression models for amputation, higher poverty rate (odds ratio for SD increase 1.20; 95% confidence interval, 1.02-1.42; P = .025) was significantly associated with the outcome. In multivariable models, neither DCI distress score nor any of its components remained significantly associated with the outcome. CONCLUSIONS: Despite known racial disparities in limb-specific outcomes, an aggregate measure of community level distress was not found to be related to outcomes. Although the poverty rate demonstrated a significant relationship with amputation in univariable analysis, this association was not found in multivariable models. Notably, non-White race emerged as a predictor of amputation, underscoring the importance of addressing racial disparities in LE outcomes. Further investigation of potential determinants of LE outcomes is needed, particularly the interaction of such factors with race.

Patient Flow and Reutilization of Crisis Services Within 30 Days in a Comprehensive Crisis System.

OBJECTIVE: Crisis services are undergoing an unprecedented expansion in the United States, but research is lacking on crisis system design. This study describes how individuals flow through a well-established crisis system and examines factors associated with reutilization of such services. METHODS: This cross-sectional study used Medicaid claims to construct episodes describing the flow of individuals through mobile crisis, specialized crisis facility, emergency department, and inpatient services. Claims data were merged with electronic health record (EHR) data for the subset of individuals receiving care at a crisis response center. A generalized estimating equation was used to calculate adjusted odds ratios for demographic, clinical, and operational factors associated with reutilization of services within 30 days of an episode's end point. RESULTS: Of 41,026 episodes, most (57.4%) began with mobile crisis services or a specialized crisis facility rather than the emergency department. Of the subset (N=9,202 episodes) with merged EHR data, most episodes (63.3%) were not followed by reutilization. Factors associated with increased odds of 30-day reutilization included Black race, homelessness, stimulant use, psychosis, and episodes beginning with mobile crisis services or ending with inpatient care. Decreased odds were associated with depression, trauma, and involuntary legal status. Most (59.3%) episodes beginning with an involuntary legal status ended with a voluntary status. CONCLUSIONS: Crisis systems can serve a large proportion of individuals experiencing psychiatric emergencies and divert them from more restrictive and costly levels of care. Understanding demographic, clinical, and operational factors associated with 30-day reutilization may aid in the design and implementation of crisis systems.

Contemporary outcomes for arterial reconstruction with non-saphenous vein cryo-preserved conduits.

OBJECTIVE: Cryopreserved (CP) products are utilized during challenging cases when autogenous or prosthetic conduit use is not feasible. Despite decades of experience with cadaveric greater saphenous vein (GSV), there is limited available data regarding the outcomes and patency of other CP products, specifically arterial and deep venous grafts. This study was designed to evaluate outcomes of non-GSV CP conduits in patients undergoing urgent, emergent, and elective arterial reconstruction at our institution. We hypothesized that non-GSV CP allografts have adequate patency and outcomes and are therefore a feasible alternative to GSV in settings where autologous graft is unavailable or prosthetic grafts are contraindicated. METHODS: This study was approved by the Institutional Review Board at our institution. We retrospectively reviewed charts of patients undergoing arterial reconstructions using CP conduits from 2010 to 2022. Data collected included demographics, comorbidities, smoking status, indications for surgery, indication for CP conduit use, anatomic reconstruction, urgency of procedure, and blood loss. Time-to-event outcomes included primary and secondary graft patency rates, follow-up amputations, and mortality; other complications included follow-up infection/reinfection and 30-day complications, including return to the operating room and perioperative mortality. Time-to-event analyses were evaluated using product-limit survival estimates. RESULTS: Of 96 identified patients receiving CP conduits, 56 patients received non-GSV conduits for 66 arterial reconstructions. The most common type of non-GSV CP product used was femoral artery (31 patients), followed by aorto-iliac artery (22 patients), and femoral vein (19 patients), with some patients receiving more than one reconstruction or CP product. Patients were mostly male (75%), with a mean age of 63.1 years and a mean body mass index of 26.7 kg/m2. Indications for CP conduit use included infection in 53 patients, hostile environment in 36 patients, contaminated field in 30 patients, tissue coverage concerns in 30 patients, inadequate conduit in nine patients, and patient preference in one patient. Notably, multiple patients had more than one indication. Most surgeries (95%) were performed in urgent or emergent settings. Supra-inguinal reconstructions were most common (53%), followed by extra-anatomic bypasses (47%). Thirty-day mortality occurred in 10 patients (19%). Fifteen patients (27%) required return to the operating room for indications related to the vascular reconstructions, with 10 (18%) cases being unplanned and five (9%) cases planned/staged. Overall survival at 6, 12, and 24 months was 80%, 68%, and 59%, respectively. Primary patency at 6, 12, and 24 months was 86%, 70%, and 62%, respectively. Amputation freedom at 6 months, 12 months, and 24 months was 98%, 95%, and 86%, respectively for non-traumatic indications. CONCLUSIONS: Non-GSV CP products may be used in complex arterial reconstructions when autogenous or prosthetic options are not feasible or available.

Neuropathy Screening for Patients with Peripheral Vascular Disease Helps to Identify Those at an Increased Risk of Amputation, Revascularization, and Death.

BACKGROUND: Peripheral neuropathy is associated with amputation risk among patients with diabetes mellitus and chronic limb-threatening ischemia (CLTI). Detection of peripheral neuropathy may help identify those who are at an increased risk, but the predictive ability of the screening tool used in patients with peripheral arterial disease (PAD) needs to be more clearly defined. METHODS: Patients referred to vascular surgery clinic for PAD were recruited from a single center. Exclusion criteria were a documented history of neuropathy or prior lower limb amputation. Screening utilized the Michigan Neuropathy Screening Instrument (MNSI). Scores >2.5 were considered abnormal and scores >4 were considered positive for peripheral neuropathy. Limb-specific outcomes of amputation and revascularization as well as a composite outcome including death were modeled using time to event analysis. RESULTS: 86 patients were recruited. Mean age was 67 ± 10.2 years, 30% were women, 24% were black. Mean ankle-brachial index was 0.74 ± 0.3. PAD symptoms at initial evaluation were claudication in 52% of patients and CLTI in 38% of patients. Neuropathy was present in 20% of the cohort with a significantly higher proportion in diabetics (34% vs. 3%; P = 0.0009). Neuropathy was more common in patients with CLTI compared to claudicants (36% vs. 9%; P = 0.011). Forty patients (47%) reached the composite outcome of amputation, revascularization, or death with a median time to event of 16 months. Abnormal MNSI examination was significantly associated with the increased risk of the composite outcome (hazard ratio = 3.19; P 0.0005). CONCLUSIONS: A significant proportion of patients presenting to vascular specialists for PAD have undiagnosed neuropathy. Patients with PAD and neuropathy have an increased risk of amputation, revascularization, and death. Expanding neuropathy screening in vascular surgery clinic visits may help to identify patients at higher risk.

Impact of San Francisco's New Street crisis response Team on Service use among people experiencing homelessness with mental and substance use disorders: A mixed methods study protocol.

Mobile crisis services for people experiencing distress related to mental health or substance use are expanding rapidly across the US, yet there is little evidence to support these specific models of care. These new programs present a unique opportunity to expand the literature by utilizing implementation science methods to inform the future design of crisis systems. This mixed methods study will examine the effectiveness and acceptability of the Street Crisis Response Team (SCRT), a new 911-dispatched multidisciplinary mobile crisis intervention piloted in San Francisco, California. First, using quantitative data from electronic health records, we will conduct an interrupted time series analysis to quantitatively examine the impacts of the SCRT on people experiencing homelessness who utilized public behavioral health crisis services in San Francisco between November 2019 and August 2022, across four main outcomes within 30 days of the crisis episode: routine care utilization, crisis care reutilization, assessment for housing services, and jail entry. Second, to understand its impact on health equity, we will analyze racial and ethnic disparities in these outcomes prior to and after implementation of the SCRT. For the qualitative component, we will conduct semi-structured interviews with recipients of the SCRT's services to understand their experiences of the intervention and to identify how the SCRT influenced their health-related trajectories after the crisis encounter. Once complete, the quantitative and qualitative findings will be further analyzed in tandem to assist with more nuanced understanding of the effectiveness of the SCRT program. This evaluation of a novel mobile crisis response program will advance the field, while also providing a model for how real-world program implementation can be achieved in crisis service settings.

Implementation of the 988 Suicide & Crisis Lifeline: Estimating State-Level Increases in Call Demand Costs and Financing.

BACKGROUND: Per federal law, "988" became the new three-digit dialing code for the National Suicide & Crisis Lifeline on July 16, 2022 (previously reached by dialing "1-800-283-TALK"). AIMS OF THE STUDY: This study aimed to produce state-level estimates of: (i) annual increases in 988 Lifeline call volume following 988 implementation, (ii) the cost of these increases, and (iii) the extent to which state and federal funding earmarked for increases in 988 Lifeline call volume are sufficient to meet call demand. METHOD: A 50 state pre-post policy implementation design was used. State-level Lifeline call volume data were obtained. For each state, we calculated the absolute difference in number of Lifeline calls in the four-month periods between August-November 2021 (pre-988 implementation) and August-November 2022 (post-988 implementation), and also expressed this difference as percent change and rate per 100,000 population. The difference call volume was multiplied by a published estimate of the cost of a single 988 Lifeline call (USD 82), and then by multiplied by three to produce annual, 12-month state-level cost increase estimates. These figures were then divided by each state's population size to generate cost estimates per state resident. State-level information on the amount of state (FY 2023) and federal SAMHSA (FY 2022) funding earmarked for 988 Lifeline centers in response to 988 implementation were obtained from legal databases and government websites and expressed as dollars per state resident. State-level differences between per state resident estimates of increased cost and funding were calculated to assess the extent to which state and federal funding earmarked for increases in 988 Lifeline call volume were sufficient to meet call demand. RESULTS: 988 Lifeline call volume increased in all states post-988 implementation (within-state mean percent change = +32.8%, SD = +20.5%). The total estimated cost needed annually to accommodate increases in 988 Lifeline call volume nationally was approximately USD 46 million. The within-state mean estimate of additional cost per state resident was +USD 0.16 (SD = +USD 0.11). The additional annual cost per state resident exceeded USD 0.40 in three states, was between USD 0.40- USD 0.30 in three states, and between USD 0.30 - USD 0.20 in seven states. Twenty-two states earmarked FY 2023 appropriations for 988 Lifeline centers in response to 988 (within-state mean per state resident = USD 1.51, SD = USD 1.52) and 49 states received SAMHSA 988 capacity building grants (within-state mean per state resident = USD 0.36, SD = USD 0.39). State funding increases exceeded the estimated cost increases in about half of states. CONCLUSIONS: The Lifeline's transition to 988 increased 988 Lifeline call volume in all states, but the magnitude of the increase and associated cost was heterogenous across states. State funding earmarked for increases in 988 Lifeline center costs is sufficient in about half of states. Sustained federal funding, and/or increases in state funding, earmarked for 988 Lifeline centers is likely important to ensuring that 988 Lifeline centers have the capacity to meet call demand in the post-988 implementation environment.

Boney abnormalities cause arterial, venous, and/or neurogenic thoracic outlet syndrome.

Background: Thoracic outlet syndrome (TOS) is a rare condition caused by compression of the neurovascular structures within the thoracic outlet. Different classifications of TOS exist depending on the neurovascular structure being compressed: neurogenic, venous, or arterial. Any of these forms can present independently or coexist with one other. TOS symptoms are sometimes precipitated by the presence of boney abnormalities that often require surgical intervention for ultimate resolution. This retrospective review will examine the presentations and outcomes of patients with TOS whose cause was a boney abnormality. Methods: A total of 73 patients who underwent thoracic outlet surgery between 2016 and 2021 were retrospectively reviewed via electronic medical records. Twelve (16%) patients demonstrated boney abnormalities on presentation causing their symptoms. The patients with boney abnormalities were analyzed based on venous, arterial, or neurogenic TOS diagnosis. Results: Of the 12 patients with boney abnormalities, 5 were classified as venous TOS, 6 patients as neurogenic TOS, and 1 as arterial TOS. The boney abnormalities were as follows: venous TOS: three clavicular fractures, one nonfused congenital clavicle, and one residual rib; neurogenic TOS: three fractured first ribs, one fractured clavicle, and two cervical ribs; and arterial TOS: fused first and second rib with bilateral cervical ribs and arterial compression. Postoperatively, there were no artery, vein, or nerve injuries. Five patients had a pneumothorax treated over night with a chest tube, and one patient had a superficial wound infection. The median hospital stay was 1 day. All patients completed physical therapy after surgery. All patients have symptom resolution at follow-up. Conclusions: Patients with boney abnormalities constitute about one-fifth of patients who can present with all three forms of TOS: neurogenic, arterial, and venous, and some will have more than one of these presentations. Results in patients undergoing surgery with boney abnormalities causing thoracic outlet syndrome are excellent with symptom resolution and without substantial complications.

Community, Hospital, and Patient Factors Contributing to Ethnoracial Disparities in Follow-Up After Psychiatric Hospitalization.

OBJECTIVE: This study used an ecosocial perspective to examine ethnoracial disparities in timely outpatient follow-up care after psychiatric hospitalization in a cohort of Medicaid recipients. METHODS: This retrospective analysis used 2012-2013 New York State Medicaid claims data for 17,488 patients ages <65 years who were treated in hospital psychiatric units and discharged to the community. Claims data were linked to other administrative data sets capturing key social conditions and determinants of mental health for non-Latinx White (White hereafter), non-Latinx Black (Black), Latinx, non-Latinx Asian/Pacific Islander (Asian/Pacific Islander), non-Latinx American Indian or Native Alaskan (American Indian or Native Alaskan), and other ethnoracial groups. Regression models were used to estimate the variations in disparities in timely follow-up care that were attributable to community, organization (i.e., hospital), and individual patient characteristics. RESULTS: Overall, 60.1% of patients attended an outpatient mental health visit within 30 days of discharge. Compared with the rate for White patients, the attendance rates were 9.5 percentage points lower for Black patients and 7.8 percentage points higher for Asian/Pacific Islander patients. No significant difference in attendance rates was found between Latinx and White patients. Community factors, specifically urban versus rural classification and county poverty status, accounted for the greatest variation in timely follow-up care in all comparisons. CONCLUSIONS: Efforts to increase connection to outpatient mental health follow-up care after psychiatric hospitalization should incorporate cultural and structural competencies to address social conditions and determinants of mental health that underly ethnoracial disparities.

Telemental health policies for college students during COVID-19.

Federal and institutional policy changes have accelerated the use of telemental health to care for college students distant from their mental health providers during the early part of the COVID-19 pandemic. Temporary measures have made telemental health more readily available, including relaxing of regulations related to interstate licensure, controlled substance prescribing, patient privacy, and reimbursement. Though early efforts are underway to sustain these changes during and in the wake of the pandemic, there are important areas in which federal and institutional policy are still lacking. Additional steps are needed to successfully implement and sustain telemental health for college students include ensuring student access to technology and Internet; proactive outreach to optimize the student's home environment, addressing concerns about safety and confidentiality; developing the means to track rapidly shifting telemental health policy changes; and developing centralized resources that enable remote providers to become familiar with involuntary commitment laws and emergency protocols.

Field Visit Contact Rate by Mobile Crisis Teams as a Crisis System Performance Metric.

OBJECTIVE: The authors investigated associations between rates of contact with individuals in distress during field visits by mobile crisis teams and client and referral source characteristics. METHODS: In this retrospective observational study of an urban mobile crisis program, call logs (N=2,581) were coded for whether an attempted field visit resulted in a client evaluation. Logistic regression analyses examined potential associations with client age, gender, race-ethnicity, primary language, living situation, insurance, and referral source. RESULTS: Contact was made with 77% of adults and 97% of children referred to mobile crisis teams. Field visit contact rates differed by age. Unsuccessful visits were more likely when the referral source was from institutional settings than from individuals. CONCLUSIONS: Approximately one-quarter of attempted field visits with adults by an urban mobile crisis team were not completed, particularly among referrals from institutional settings. As mobile crisis services proliferate, field visit contact rate could be a key performance metric for these critical services.

Excellent results seen with both transaxillary and infraclavicular approaches to first rib resection in patients with subclavian vein thrombosis.

BACKGROUND: Venous thoracic outlet syndrome (VTOS) is a debilitating condition with several well-documented treatment paradigms. We reviewed the outcomes from a large academic institution of patients who had undergone transaxillary first rib resection with delayed venography (TA) or infraclavicular first rib and subclavius muscle resection with concomitant venography (ICV) for VTOS with subclavian vein thrombosis. METHODS: We performed a retrospective review of the medical records of all patients who had undergone first rib resection and scalenectomy for VTOS with subclavian vein thrombosis at a single academic institution. The demographics, presentation, operative records, and outcomes were collected. Descriptive statistics were used to compare the two groups. RESULTS: A total of 73 patients had undergone first rib resection for VTOS during the study period. Of the 73 patients, 36 (49%) had presented with thrombosis of the subclavian vein and were included in the present review. Of the 36 patients, 26 (72%) had undergone TA and 10 (28%) had undergone ICV. No significant differences were seen between the two groups in female gender (54% vs 50%; P = 1.00) or age (28.7 years vs 29.5 years; P = .88). A higher percentage of the ICV group had undergone preoperative thrombolysis (70% vs 27%; P = .02). All the patients in the ICV group had undergone intraoperative balloon venoplasty at resection. The mean time from thrombosis to resection was 2.3 months. All of the TA group had undergone venography at 2 weeks postoperatively. Venography had revealed 15 stenotic veins requiring venoplasty, 8 widely patent veins, 1 acutely thrombosed vein, and 3 chronically occluded veins. The time from initial thrombosis to surgical intervention was 10 months for the patent group, 6 months for the stenotic group, and 4 months for the occluded group. In the TA group, 19% of the patients had required chest tube placement intraoperatively for pneumothorax. In the ICV group, complications included postoperative hematoma (n = 1), wound infection (n = 1), and hemothorax (n = 1). The mean length of stay was 1.04 days for the TA group and 2.00 days for the ICV group (P < .0001). The mean follow-up was 10.4 months and 15.8 months for the TA and ICV groups, respectively. No mortalities were reported. No differences in the vein patency rates were seen between the two groups at follow-up (TA, 93%; vs ICV, 100%; P = 1.00). All the patients were asymptomatic at follow-up. CONCLUSIONS: The outcomes for the patients who had undergone TA or ICV for subclavian vein thrombosis were excellent with no mortality and few complications. The subclavian vein patency rates were high, and all the patients were asymptomatic at follow-up.

A Rapid Review of "Low-Threshold" Psychiatric Medication Prescribing: Considerations for Street Medicine and Beyond.

OBJECTIVE: No widely accepted clinical guidelines, and scant directly applicable pragmatic research, are available to guide the prescription of psychiatric medications in "low-threshold" outpatient settings, such as street outreach, urgent care, and crisis care, as well as walk-in, shelter, and bridge and transition clinics. Providers frequently prescribe medications in these settings without patients' having firm psychiatric diagnoses and without medical records to guide clinical decision making. Persons who receive medications in these settings often seek help voluntarily and intermittently for mental illness symptoms. However, because of structural and individual factors, such patients may not engage in longitudinal outpatient psychiatric care. The authors reviewed the literature on psychiatric medication prescribing in low-threshold settings and offer clinical considerations for such prescribing. METHODS: The authors conducted a rapid literature review (N=2,215 abstracts), which was augmented with up-to-date clinical prescribing literature, the authors' collective clinical experience, and DSM-5 section II diagnostic criteria to provide considerations for prescribing medications in low-threshold settings. RESULTS: For individuals for whom diagnostic uncertainty is prominent, a symptom-based diagnostic and treatment approach may be best suited to weigh the risks and benefits of medication use in low-threshold settings. Practical considerations for treating patients with clinical presentations of psychosis and trauma, as well as mood, anxiety, and substance use disorders, in low-threshold settings are discussed. CONCLUSIONS: An urgent need exists to invest in pragmatic research and guideline development to delineate best-practice prescribing in low-threshold settings.

Automated Electronic Frailty Index is Associated with Non-home Discharge in Patients Undergoing Open Revascularization for Peripheral Vascular Disease.

BACKGROUND: Frailty is associated with adverse surgical outcomes including post-operative complications, needs for post-acute care, and mortality. While multiple frailty screening tools exist, most are time and resource intensive. Here we examine the association of an automated electronic frailty index (eFI), derived from routine data in the Electronic Health Record (EHR), with outcomes in vascular surgery patients undergoing open, lower extremity revascularization. METHODS: A retrospective analysis at a single academic medical center from 2015 to 2019 was completed. Information extracted from the EHR included demographics, eFI, comorbidity, and procedure type. Frailty status was defined as fit (eFI≤0.10), pre-frail (0.100.21). Outcomes included length of stay (LOS), 30-day readmission, and non-home discharge. RESULTS: We included 295 patients (mean age 65.9 years; 31% female), with the majority classified as pre-frail (57%) or frail (32%). Frail patients exhibited a higher degree of comorbidity and were more likely to be classified as American Society of Anesthesiologist class IV (frail: 46%, pre-frail: 27%, and fit: 18%, P = 0.0012). There were no statistically significant differences in procedure type, LOS, or 30-day readmissions based on eFI. Frail patients were more likely to expire in the hospital or be discharged to an acute care facility (31%) compared to pre-frail (14%) and fit patients (15%, P = 0.002). Adjusting for comorbidity, risk of non-home discharge was higher comparing frail to pre-frail patients (OR 3.01, 95% CI 1.40-6.48). DISCUSSION: Frail patients, based on eFI, undergoing elective, open, lower extremity revascularization were twice as likely to not be discharged home.
