Abstract
PURPOSE To characterize antibiotic utilization for outpatient community-acquired pneumonia (CAP) in the United States. METHODS We conducted a cohort study among adults 18-64 years diagnosed with outpatient CAP and a same-day guideline-recommended oral antibiotic fill in the MarketScan® Commercial Database (2008-2019). We excluded patients coded for chronic lung disease or immunosuppressive disease; recent hospitalization or frequent healthcare exposure (e.g., home wound care, patients with cancer); recent antibiotics; or recent infection. We characterized utilization of broad-spectrum antibiotics (respiratory fluoroquinolone, β-lactam + macrolide, β-lactam + doxycycline) versus narrow-spectrum antibiotics (macrolide, doxycycline) overall and by patient- and provider-level characteristics. Per 2007 IDSA/ATS guidelines, we stratified analyses by otherwise healthy patients and patients with comorbidities (coded for diabetes; chronic heart, liver, or renal disease; etc.). RESULTS Among 263 914 otherwise healthy CAP patients, 35% received broad-spectrum antibiotics (not recommended); among 37 161 CAP patients with comorbidities, 44% received broad-spectrum antibiotics (recommended). Ten-day antibiotic treatment durations were the most common for all antibiotic classes except macrolides. From 2008 to 2019, broad-spectrum antibiotic use substantially decreased from 45% to 19% in otherwise healthy patients (average annual percentage change [AAPC], -7.5% [95% CI -9.2%, -5.9%]), and from 55% to 29% in patients with comorbidities (AAPC, -5.8% [95% CI -8.8%, -2.6%]). In subgroup analyses, broad-spectrum antibiotic use varied by age, geographic region, provider specialty, and provider location. CONCLUSIONS Real-world use of broad-spectrum antibiotics for outpatient CAP declined over time but remained common, irrespective of comorbidity status. Prolonged duration of therapy was common. Antimicrobial stewardship is needed to aid selection according to comorbidity status and to promote shorter courses.

Abstract
Objective To determine the relationship between severe acute respiratory syndrome coronavirus 2 infection, hospital-acquired infections (HAIs), and mortality. Design Retrospective cohort. Setting Three St. Louis, MO hospitals. Patients Adults admitted ≥48 hours from January 1, 2017 to August 31, 2020. Methods Hospital-acquired infections were defined as those occurring ≥48 hours after admission and were based on positive urine, respiratory, and blood cultures. Poisson interrupted time series compared mortality trajectory before (beginning January 1, 2017) and during the first 6 months of the pandemic. Multivariable logistic regression models were fitted to identify risk factors for mortality in patients with an HAI before and during the pandemic. A time-to-event analysis considered time to death and discharge by fitting Cox proportional hazards models. Results Among 6,447 admissions with subsequent HAIs, patients were predominantly White (67.9%), with more females (50.9% vs 46.1%, P = .02), having slightly lower body mass index (28 vs 29, P = .001), and more having private insurance (50.6% vs 45.7%, P = .01) in the pre-pandemic period. In the pre-pandemic era, there were 1,000 (17.6%) patient deaths, whereas there were 160 deaths (21.3%, P = .01) during the pandemic. A total of 53 (42.1%) coronavirus disease 2019 (COVID-19) patients died having an HAI. Age and comorbidities increased the risk of death in patients with COVID-19 and an HAI. During the pandemic, Black patients with an HAI and COVID-19 were more likely to die than White patients with an HAI and COVID-19. Conclusions In three Midwestern hospitals, patients with concurrent HAIs and COVID-19 were more likely to die if they were Black, elderly, and had certain chronic comorbidities.

Abstract
In a US adult population aged <65 years, attributable costs due to Clostridioides difficile infection (CDI) were highest in persons with hospital onset and lowest in those with community-associated CDI treated outside a hospital. The economic burden of CDI in younger adults underscores the need for additional CDI-preventive strategies.

Abstract
BACKGROUND The dimorphic mycoses (DMs) of the United States-Histoplasma, Coccidioides, and Blastomyces-commonly known as endemic mycoses of North America (in addition to Paracoccidioides) are increasingly being diagnosed outside their historical areas of endemicity. Despite this trend, the maps outlining their geographic distributions have not been updated in more than half a century using a large, nationwide database containing individual-patient-level data. METHODS This was a retrospective analysis of >45 million Medicare fee-for-service beneficiaries from 1 January 2007 through 31 December 2016. Diagnoses of histoplasmosis, coccidioidomycosis, and blastomycosis were defined by International Classification of Diseases, Ninth/10th Revision, codes. The primary outcome was the incidence of histoplasmosis, coccidioidomycosis, and blastomycosis for each US county. Clinically meaningful thresholds for incidence were defined as 100 cases/100 000 person-years for histoplasmosis and coccidioidomycosis and 50 cases/100 000 person-years for blastomycosis. RESULTS There were 79 749 histoplasmosis, 37 726 coccidioidomycosis, and 6109 blastomycosis diagnoses in unique persons from 2007-2016 across 3143 US counties. Considering all US states plus Washington, DC, 94% (48/51) had ≥1 county above the clinically relevant threshold for histoplasmosis, 69% (35/51) for coccidioidomycosis, and 78% (40/51) for blastomycosis. CONCLUSIONS Persons with histoplasmosis, coccidioidomycosis, and blastomycosis are diagnosed in significant numbers outside their historical geographic distributions established >50 years ago. Clinicians should consider DM diagnoses based on compatible clinical syndromes with less emphasis placed on patients' geographic exposure. Increased clinical suspicion leading to a subsequent increase in DM diagnostic testing would likely result in fewer missed diagnoses, fewer diagnostic delays, and improved patient outcomes.

Abstract
BACKGROUND Little is known about the clinical and financial consequences of inappropriate antibiotics. We aimed to estimate the comparative risk of adverse drug events and attributable healthcare expenditures associated with inappropriate versus appropriate antibiotic prescriptions for common respiratory infections. METHODS We established a cohort of adults aged 18 to 64 years with an outpatient diagnosis of a bacterial (pharyngitis, sinusitis) or viral respiratory infection (influenza, viral upper respiratory infection, nonsuppurative otitis media, bronchitis) from 1 April 2016 to 30 September 2018 using Merative MarketScan Commercial Database. The exposure was an inappropriate versus appropriate oral antibiotic (ie, non-guideline-recommended vs guideline-recommended antibiotic for bacterial infections; any vs no antibiotic for viral infections). Propensity score-weighted Cox proportional hazards models were used to estimate the association between inappropriate antibiotics and adverse drug events. Two-part models were used to calculate 30-day all-cause attributable healthcare expenditures by infection type. RESULTS Among 3 294 598 eligible adults, 43% to 56% received inappropriate antibiotics for bacterial and 7% to 66% for viral infections. Inappropriate antibiotics were associated with increased risk of several adverse drug events, including Clostridioides difficile infection and nausea/vomiting/abdominal pain (hazard ratio, 2.90; 95% confidence interval, 1.31-6.41 and hazard ratio, 1.10; 95% confidence interval, 1.03-1.18, respectively, for pharyngitis). Thirty-day attributable healthcare expenditures were higher among adults who received inappropriate antibiotics for bacterial infections ($18-$67) and variable (-$53 to $49) for viral infections. CONCLUSIONS Inappropriate antibiotic prescriptions for respiratory infections were associated with increased risks of patient harm and higher healthcare expenditures, justifying a further call to action to implement outpatient antibiotic stewardship programs.

Abstract
BACKGROUND Although hospital-onset Clostridioides difficile infection (CDI) is associated with significant healthcare costs, the economic burden of CDI with onset in other facilities or the community has not been well studied. METHODS Incident CDI cases were identified using 2011-2017 Medicare fee-for-service data. Controls were randomly selected in a 4:1 ratio matching to the CDI case surveillance definition. Inverse probability of exposure weights were used to balance on measured confounders. One-, 3-, and 5-year cumulative costs attributable to CDI were computed using a 3-part estimator (parametric survival model and pair of 2-part models predicting costs separately in intervals where death did and did not occur). RESULTS A total of 60 492 CDI cases were frequency-matched to 241 968 controls. One-, 3-, and 5-year adjusted attributable costs were highest for hospital-onset CDI at $14 257, $18 953, and $21 792, respectively, compared with hospitalized controls and lowest for community-associated CDI compared with community controls at $1013, $3161, and $6454, respectively. Adjusted 1-, 3-, and 5-year costs attributable to community-onset healthcare facility-associated CDI were $8222, $13 066, and $16 329 and for other healthcare facility-onset CDI were $5345, $6764, and $7125, respectively. CONCLUSIONS Economic costs attributable to CDI in elderly persons were highest for hospital-onset and community-onset healthcare facility-associated CDI. Although lower, attributable costs due to CDI were significantly higher in cases with CDI onset in the community or other healthcare facility than for comparable persons without CDI. Additional strategies to prevent CDI in the elderly are needed to reduce morbidity and healthcare expenditures.

Abstract
OBJECTIVE To evaluate risk factors for hospital-acquired infection (HAI) in patients during the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, including historical and concurrent cohorts. DESIGN Retrospective cohort. SETTING Three Missouri hospitals, data from 1st January 2017 to 30th September 2020. PARTICIPANTS Patients aged ≥18 years and admitted for ≥48 h. METHODS Univariate and multi-variate Cox proportional hazards models incorporating the competing risk of death were used to determine risk factors for HAI. A-priori sensitivity analyses were performed to assess the robustness of the urine-, blood- and respiratory-culture-based HAI definition. RESULTS The cohort included 254,792 admissions, with 7147 (2.8%) HAIs (1661 blood, 3407 urine, 2626 respiratory). Patients with SARS-CoV-2 had increased risk of HAI (adjusted hazards ratio 1.65, 95% confidence interval 1.38-1.96), and SARS-CoV-2 infection was one of the strongest risk factors for development of HAI. Other risk factors for HAI included certain admitting services, chronic comorbidities, intensive care unit stay during index admission, extremes of body mass index, hospital, and selected medications. Factors associated with lower risk of HAI included year of admission (declined over the course of the study), admitting service and medications. Risk factors for HAI were similar in sensitivity analyses restricted to patients with diagnostic codes for pneumonia/upper respiratory infection and urinary tract infection. CONCLUSIONS SARS-CoV-2 was associated with significantly increased risk of HAI.

Abstract
PURPOSE Acute otitis media (AOM) is a common indication for antibiotics in children. We sought to characterize the frequency of nonguideline concordant antibiotic therapy for AOM in the United States, by agent and duration. METHODS Using national administrative claims data (2016-2019), we identified children aged 6 months to 17 years with an oral antibiotic dispensed within 3 days of a new diagnosis of suppurative AOM. Use of nonguideline concordant agents and durations, defined based on national treatment guidelines, were summarized by age, race, rurality, region, and insurance type. Subsequent oral antibiotic dispensing within the year after AOM diagnosis was also evaluated. We created sunburst diagrams to visualize longitudinal patterns of within-person antibiotic utilization for AOM, by agent and duration. RESULTS We identified 789 424 eligible commercially-insured and 502 239 medicaid-insured children. Among commercially insured children, 35% received nonguideline concordant agents for AOM, including cefdinir (16%), amoxicillin-clavulanate (12%), and azithromycin (7%). Fewer children age <2 years received a nonguideline concordant initial agent (27%) compared to age ≥6 years (41%). More children age <2 years received three or more antibiotics over the following year (34% vs. 3% for children age ≥6 years). The most common treatment duration was 10 days for all ages; treatment duration for the initial antibiotic was nonguideline concordant for 95% and 89% of children age 2-5 years and ≥6 years, respectively. Patterns were similar for medicaid-insured children. CONCLUSIONS Nonguideline concordant antibiotic use is common when treating AOM in children, including use of broad-spectrum agents and longer-than-recommended antibiotic durations.

Abstract
IMPORTANCE Nonguideline antibiotic prescribing for the treatment of pediatric infections is common, but the consequences of inappropriate antibiotics are not well described. OBJECTIVE To evaluate the comparative safety and health care expenditures of inappropriate vs appropriate oral antibiotic prescriptions for common outpatient pediatric infections. DESIGN, SETTING, AND PARTICIPANTS This cohort study included children aged 6 months to 17 years diagnosed with a bacterial infection (suppurative otitis media [OM], pharyngitis, sinusitis) or viral infection (influenza, viral upper respiratory infection [URI], bronchiolitis, bronchitis, nonsuppurative OM) as an outpatient from April 1, 2016, to September 30, 2018, in the IBM MarketScan Commercial Database. Data were analyzed from August to November 2021. EXPOSURES Inappropriate (ie, non-guideline-recommended) vs appropriate (ie, guideline-recommended) oral antibiotic agents dispensed from an outpatient pharmacy on the date of infection. MAIN OUTCOMES AND MEASURES Propensity score-weighted Cox proportional hazards models were used to estimate hazards ratios (HRs) and 95% CIs for the association between inappropriate antibiotic prescriptions and adverse drug events. Two-part models were used to calculate 30-day all-cause attributable health care expenditures by infection type. National-level annual attributable expenditures were calculated by scaling attributable expenditures in the study cohort to the national employer-sponsored insurance population. RESULTS The cohort included 2 804 245 eligible children (52% male; median [IQR] age, 8 [4-12] years). Overall, 31% to 36% received inappropriate antibiotics for bacterial infections and 4% to 70% for viral infections. Inappropriate antibiotics were associated with increased risk of several adverse drug events, including Clostridioides difficile infection and severe allergic reaction among children treated with a nonrecommended antibiotic agent for a bacterial infection (among patients with suppurative OM, C. difficile infection: HR, 6.23; 95% CI, 2.24-17.32; allergic reaction: HR, 4.14; 95% CI, 2.48-6.92). Thirty-day attributable health care expenditures were generally higher among children who received inappropriate antibiotics, ranging from $21 to $56 for bacterial infections and from -$96 to $97 for viral infections. National annual attributable expenditure estimates were highest for suppurative OM ($25.3 million), pharyngitis ($21.3 million), and viral URI ($19.1 million). CONCLUSIONS AND RELEVANCE In this cohort study of children with common infections treated in an outpatient setting, inappropriate antibiotic prescriptions were common and associated with increased risks of adverse drug events and higher attributable health care expenditures. These findings highlight the individual- and national-level consequences of inappropriate antibiotic prescribing and further support implementation of outpatient antibiotic stewardship programs.

Abstract
PURPOSE/BACKGROUND Antipsychotic drugs are well established to alter circulating prolactin levels by blocking dopamine D2 receptors in the pituitary. Prolactin activates many genes important in the development of breast cancer. Prior studies have found an association with antipsychotic use and risk of breast cancer. METHODS/PROCEDURES The IBM MarketScan Commercial and Medicaid Databases were used to establish a large, observational cohort of women taking antipsychotics drugs compared with anticonvulsants or lithium. A new user design was used that required 12 months of insurance enrollment before the first antipsychotic or anticonvulsant/lithium prescription. Invasive breast cancer was identified using diagnostic codes. Multivariable Cox proportional hazards models were used to evaluate the risk of breast cancer with antipsychotic drug exposure controlling for age and other risk factors. FINDINGS/RESULTS A total of 914 cases (0.16%) of invasive breast cancer were identified among 540,737 women. Exposure to all antipsychotics was independently associated with a 35% increased risk of breast cancer (aHR [adjusted hazard ratio], 1.35; 95% confidence interval, 1.14-1.61). Category 1 drugs (high prolactin) were associated with a 62% increased risk (aHR, 1.62; 95% CI, 1.30-2.03), category 2 drugs a 54% increased risk (aHR, 1.54; 95% CI, 1.19-1.99), and category 3 drugs were not associated with breast cancer risk. IMPLICATIONS/CONCLUSIONS In the largest study of antipsychotics taken by US women, a higher risk between antipsychotic drug use and increased risk for breast cancer was observed, with a differential higher association with antipsychotic categories that elevate prolactin. Our study confirms other recent observational studies of increased breast cancer risk with antipsychotics that elevate prolactin.

Abstract
Fecal glucocorticoid metabolite (FGM) concentrations, activity, and personality were assessed for 35 fennec foxes (Vulpes zerda) to determine whether animals managed as ambassadors differed from exhibit or off-exhibit animals. A FGM assay, pedometer, and personality assessment tool were validated. Then, fecal samples and movement data were collected during winter and summer periods. Handling was recorded, and the personality of each fox was evaluated. Generalized linear mixed models assessed the relationships between FGM concentrations, activity, personality, handling, sex, season, rearing type, and role. FGM concentrations did not differ in relation to role or handling. Foxes were most active at night; the time of peak activity did not vary with role or handling. Foxes were more active in winter; males were more active than females, and ambassador foxes were more active than off-exhibit animals. Hand-reared foxes were more sociable, and, at one institution, ambassador foxes were more sociable than foxes in other roles. These results suggest that management for ambassador programs is not associated with changes in glucocorticoid production or circadian patterns but may increase activity and be associated with greater sociability.

Abstract
BACKGROUND AND AIMS Persons with opioid use disorder (OUD) and co-occurring alcohol use disorder (AUD) are understudied. We identified whether co-occurring AUD was associated with OUD treatment type, compared associations between treatment type and six-month treatment retention and determined whether co-occurring AUD moderated these relationships. METHODS We used an observational cohort study design to analyze insurance claims data from 2011 to 2016 from persons aged 12-64 with an opioid abuse or opioid dependence diagnosis and OUD treatment claim. Our unit of analysis was the treatment episode; we used logistic regression for analyses. RESULTS Of 211,047 treatment episodes analyzed, 14 % had co-occurring alcohol abuse or dependence diagnoses. Among persons with opioid dependence, persons with co-occurring alcohol dependence were 25 % less likely to receive medication treatment relative to those without AUD. Further, alcohol dependence was associated with decreased likelihood of treatment with buprenorphine (AOR 0.47, 95 % CI 0.44-0.49) or methadone (AOR 0.31, 95 % CI 0.28-0.35) and increased likelihood of treatment with extended-release (AOR 1.36, 95 % CI 1.21-1.54) or oral (AOR 1.73, 95 % CI 1.57-1.90) naltrexone relative to psychosocial treatment. Buprenorphine and methadone were associated with highest retention prevalence regardless of OUD or AUD severity. Co-occurring alcohol abuse or dependence did not meaningfully change retention prevalence associated with buprenorphine or methadone. Co-occurring AUD was not associated with improved retention among persons receiving either formulation of naltrexone. CONCLUSIONS Buprenorphine and methadone are associated with relatively high likelihood of treatment retention among persons opioid and alcohol dependence, but are disproportionately under-prescribed.

Abstract
BACKGROUND Important questions exist regarding the comparative effectiveness of alternative childhood vaccine schedules; however, optimal approaches to studying this complex issue are unclear. METHODS We applied methods for studying dynamic treatment regimens to estimate the comparative effectiveness of different rotavirus vaccine (RV) schedules for preventing acute gastroenteritis-related emergency department (ED) visits or hospitalization. We studied the effectiveness of six separate protocols: one- and two-dose monovalent rotavirus vaccine (RV1); one-, two-, and three-dose pentavalent rotavirus vaccine (RV5); and no RV vaccine. We used data on all infants to estimate the counterfactual cumulative risk for each protocol. Infants were censored when vaccine receipt deviated from the protocol. Inverse probability of censoring-weighted estimation addressed potentially informative censoring by protocol deviations. A nonparametric group-based bootstrap procedure provided statistical inference. RESULTS The method yielded similar 2-year effectiveness estimates for the full-series protocols; weighted risk difference estimates comparing unvaccinated children to those adherent to either full-series (two-dose RV1, three-dose RV5) corresponded to four fewer hospitalizations and 12 fewer ED visits over the 2-year period per 1,000 children. We observed dose-response relationships, such that additional doses further reduced risk of acute gastroenteritis. Under a theoretical intervention to fully vaccinate all children, the 2-year risk differences comparing full to observed adherence were 0.04% (95% CI = 0.03%, 0.05%) for hospitalizations and 0.17% (95% CI = 0.14%, 0.19%) for ED visits. CONCLUSIONS The proposed approach can generate important evidence about the consequences of delaying or skipping vaccine doses, and the impact of interventions to improve vaccine schedule adherence.

Abstract
OBJECTIVES Post-traumatic stress disorder, depression, and anxiety have all been found in parents of PICU survivors. How these research findings translate to actual use of mental health services by parents remains unknown. DESIGN Retrospective observational cohort study. SETTING Insurance claims data from 2006 to 2013 obtained from the IBM MarketScan Commercial Database. PATIENTS Parents of PICU survivors. INTERVENTIONS We examined rates of: 1) mental health diagnoses, 2) outpatient mental health visits, and 3) prescriptions for antidepressants and anxiolytics among parents, 6 months before and 6 months after their child's PICU admission, using each parent as their own control. MEASUREMENTS AND MAIN RESULTS Of the 95,070 parents identified, 9.5% received a new mental health diagnosis in the 6 months after their child's PICU hospitalization, which represented a 110% increase from pre-PICU rates. A smaller proportion of parents were given new prescriptions for antidepressants (3.4%) and anxiolytics (3.9%) in the 6 months after their child's PICU hospitalization. Mothers were twice as likely to receive a new mental health diagnosis and be taking a new medication than fathers in the post-PICU period. The parental diagnosis of acute stress disorder or post-traumatic stress disorder increased by 87% from the pre-PICU to the post-PICU period. CONCLUSIONS After their child's PICU hospitalization, the proportion of parents with a new mental health diagnosis nearly doubled. Mothers were at nearly twice the risk of receiving a new mental health diagnosis and receiving a new mental health medication compared with fathers. The proportion of parents receiving mental healthcare is much lower than the proportion reporting mental health symptoms in long-term outcomes studies. Whether this indicates a gap in healthcare delivery for parents with mental health symptoms remains unknown.

Abstract
BACKGROUND Preoperative opioid use is associated with increased health care use after elective abdominal surgery. However, the scope of preoperative opioid use and its association with outcomes have not been described in elective pulmonary resection. This study aimed to characterize prevalent preoperative opioid use in patients undergoing elective pulmonary resection and compare clinical outcomes between patients with and without preoperative opioid exposure. METHODS The study investigators assembled a retrospective cohort of adult patients undergoing elective pulmonary resection by using the IBM Watson Health MarketScan Database (2007 to 2015). The study compared opioid-naïve patients with patients with a history of preoperative opioid exposure (>0 morphine milligram equivalent prescription filled within 90 days before surgery). Multivariable logistic and linear regressions adjusting for patient sociodemographic, comorbidity, and operative characteristics were used to compare odds of postoperative complication, prolonged length-of-stay (>14 days), 30-day postdischarge emergency department visits, 90-day readmissions, and 90-day costs. RESULTS The study identified 14,373 patients, 4502 (31.3%) of whom had opioid exposure before pulmonary resection. In multivariable regression, patients with preoperative opioid exposure had significantly higher odds of experiencing a prolonged length of stay (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.11 to 1.58), 30-day emergency department visits (OR, 1.24; 95% CI, 1.01 to 1.41), and 90-day readmissions (OR, 1.41; 95% CI, 1.28 to 1.55). Adjusted 90-day costs were approximately 5% higher for patients with preoperative opioid use (P < .001). CONCLUSIONS One-third of patients who underwent pulmonary resection used opioids preoperatively and were at risk of experiencing adverse outcomes and having significantly higher health care use. They represent a unique high-risk population that will require novel, targeted interventions.

Abstract
BACKGROUND AND AIMS Adolescents with opioid use disorder (OUD) are an understudied and vulnerable population. We examined the association between age and six-month treatment retention, and whether any such association was moderated by medication treatment. METHODS In this retrospective cohort study, we used an insurance database with OUD treatment claims from 2006-2016. We examined 261,356 OUD treatment episodes in three age groups: adolescents (ages 12-17), young adults (18-25) and older adults (26-64). We used logistic regression to estimate prevalence of six-month retention before and after stratification by treatment type (buprenorphine, naltrexone, or psychosocial only). Insurance differences (commercial vs Medicaid) in medication treatment prevalence were also assessed. RESULTS Adolescents were less likely to be retained compared to adults (17.6 %; 95 % CI 16.5-18.7 % for adolescents; 25.1 %; 95 % CI 24.7-25.4 % for young adults; 33.3 %; 95 % CI 33.0-33.5 % for older adults). This disparity was reduced after adjusting for treatment type. For all ages, buprenorphine was more strongly associated with retention than naltrexone or psychosocial treatment. Adolescents who received buprenorphine were more than four times as likely to be retained in treatment (44.8 %; 95 % CI 40.6-49.0) compared to those who received psychosocial services (9.7 %; 95 % CI 8.8-10.8). Persons with commercial insurance were more likely to receive medication than those with Medicaid (73 % vs 36 %, (χ2 = 38,042.6, p < .001). CONCLUSIONS Age disparities in six-month treatment retention are strongly related to age disparities in medication treatment. Results point to need for improved implementation of medication treatment for persons with OUD, regardless of age or insurance status.

BACKGROUND High-dose influenza vaccine (HDV) is an alternative vaccination strategy in patients with end-stage renal disease (ESRD), though the safety of HDV has not been evaluated in this population. The objective of this study was to estimate the relative occurrence of adverse vaccine reactions in patients with ESRD following vaccination with HDV compared with standard-dose influenza vaccine (SDV). METHODS Using data from the United States Renal Data System, we identified patients with ESRD aged ≥ 65 years at influenza vaccination during yearly influenza seasons from 2010 through 2016. Patients were followed after vaccination to observe serious (anaphylaxis, angioedema, seizure, encephalopathy, Guillain-Barré syndrome [GBS], and short-term, all-cause mortality) and milder (urticaria/hives, rash, pain in limb, cellulitis, myalgia/myositis, fever, nausea and vomiting, diarrhea, and syncope) adverse events. Propensity score-weighted hazard ratios (HRs) and 95% confidence intervals (CIs) for HDV versus SDV were estimated with Cox proportional hazards models. RESULTS Of 520,876 vaccinations observed (mean age = 74.7 years at vaccination; 63% white race), 7.4% were HDV. For serious events, the weighted HRs were null for seizure, encephalopathy, and mortality and inestimable due to too few cases for anaphylaxis, angioedema, and GBS. For milder vaccine reactions, the weighted HRs demonstrated generally increased risks in the HDV group, including rash (HR = 1.86; 95% CI, 1.34-2.57), diarrhea (HR = 1.26; 95% CI, 1.07-1.50), pain in limb (HR = 1.23; 95% CI, 1.12-1.34), and myalgia/myositis (HR = 1.16; 95% CI, 1.04-1.30). CONCLUSIONS The risks of serious adverse events were low and similar between treatment groups; however, HDV recipients had increased risks of several milder adverse events compared with SDV recipients, consistent with clinical trial findings in the general population of older adults. These results add important information to inform the risk-benefit tradeoff of the use of HDV versus SDV in patients with ESRD.

Abstract
RATIONALE & OBJECTIVE Studies of patients on maintenance dialysis therapy suggest that standard-dose influenza vaccine (SDV) may not prevent influenza-related outcomes. Little is known about the comparative effectiveness of SDV versus high-dose influenza vaccine (HDV) in this population. STUDY DESIGN Cohort study using data from the US Renal Data System. SETTING & PARTICIPANTS 507,552 adults undergoing in-center maintenance hemodialysis between the 2010 to 2011 and 2014 to 2015 influenza seasons. EXPOSURES SDV and HDV. OUTCOMES All-cause mortality, hospitalization due to influenza or pneumonia, and influenza-like illness during the influenza season. ANALYTIC APPROACH Patients were eligible for inclusion in multiple yearly cohorts; thus, our unit of analysis was the influenza patient-season. To examine the relationship between vaccine dose and effectiveness outcomes, we estimated risk differences and risk ratios using propensity score weighting of Kaplan-Meier functions, accounting for a wide range of patient- and facility-level characteristics. For nonmortality outcomes, we used competing-risk methods to account for the high mortality rate in the dialysis population. RESULTS Within 225,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. We observed similar risk estimates for HDV and SDV recipients for mortality (risk difference, -0.08%; 95% CI, -0.85% to 0.80%), hospitalization due to influenza or pneumonia (risk difference, 0.15%; 95% CI, -0.69% to 0.93%), and influenza-like illness (risk difference, 0.00%; 95% CI, -1.50% to 1.08%). Our findings were similar among adults younger than 65 years, as well as within other subgroups defined by influenza season, age group, dialysis vintage, month of influenza vaccination, and vaccine valence. LIMITATIONS Residual confounding and outcome misclassification. CONCLUSIONS The HDV does not appear to provide additional protection beyond the SDV against all-cause mortality or influenza-related outcomes for adults undergoing hemodialysis. The additional cost and side effects associated with HDV should be considered when offering this vaccine. Future studies of HDV and other influenza vaccine strategies are warranted.

Abstract
PURPOSE Health plan disenrollment occurs frequently in commercial insurance claims databases. If individuals who disenroll are different from those who remain enrolled, informative censoring may bias descriptive statistics as well as estimates of causal effect. We explored whether patterns of disenrollment varied by patient or health plan characteristics. METHODS In a large cohort of commercially insured adults (2007-2013), we examined two primary outcomes: (a) within-year disenrollment between January 1 and December 30, which was considered to occur due to patient disenrollment from the health plan, and (b) end-of-year disenrollment on December 31, which was considered to occur due to either patient disenrollment from the health plan or withdrawal of the entire health plan from the commercial insurance database. In yearly cohorts, we identified factors independently associated with disenrollment by using log-binomial regression models to estimate risk ratios (RR) and 95% confidence intervals (CI). RESULTS Among 2 053 100 unique patient years, the annual proportion of within-year disenrollment remained steady across years (range, 13% to 14%) whereas the annual proportion of end-of-year disenrollment varied widely (range, 8% to 26%). Independent predictors of within-year disenrollment were related to health status, including age, comorbidities, frailty, hospitalization, emergency room visits, use of durable medical equipment, use of preventive care, and use of prescription medications. In contrast, independent predictors of end-of-year disenrollment were related to health plan characteristics including insurance plan type and geographic characteristics. CONCLUSIONS Differential risk of disenrollment suggests that analytic approaches to address selection bias should be considered in studies using commercial insurance databases.

Abstract
Association of Zoos and Aquariums (AZA) institutions provide a variety of benefits to visitors. However, one area that has received little study is the direct human health benefits from zoo and aquarium visits. With the increase in stress related non-infectious diseases in industrialized countries, understanding the extent of these benefits is important. We studied the effects on visitor stress of an experience at a touch tank exhibit featuring stingrays, sharks, and horseshoe crabs. Stress was measured by physiological and psychological parameters. Heart rate was recorded before, during, and after interacting with the animals, and mood was assessed before and after the experience using a psychological instrument. Multilevel models of heart rate show a quadratic trend, with heart rate elevated (b = -3.01, t = 26.4, P < 0.001) and less variable (b = 3.60, t = 15.9, P < 0.001) while touching the animals compared to before or after. Wilcoxon signed-rank tests on mood data suggest that most visitors felt happier (V = 174.5, P < 0.001), more energized (V = 743.5, P < 0.001), and less tense (V = 5618, P < 0.001) after the experience. This suggests that interacting with animals led to a physiological response during interactions reminiscent of a theme park experience along with a decrease in mental stress. The effects of confounding variables such as crowd size are also discussed. Further studies should be conducted to help deepen our understanding of the health benefits of experiences at AZA institutions.
