Abstract
BACKGROUND Hepatitis B virus (HBV) and latent tuberculosis infection are associated with a significant global burden, but both are underdiagnosed and undertreated. We described the screening patterns and risk factors for co-infection with latent tuberculosis and HBV within a large healthcare system. METHODS Using data from Kaiser Permanente Southern California during 2008-2019, we described HBV infections, defined as a positive HBV surface antigen, e-antigen, or DNA test, and latent tuberculosis, defined as a positive Mantoux tuberculin skin test or interferon-gamma release assay test. We estimated adjusted odds ratios (aOR) for co-infection among screened adults with either infection. RESULTS Among 1997 HBV patients screened for latent tuberculosis, 23.1% were co-infected, and among 35,820 patients with latent tuberculosis screened for HBV, 1.3% were co-infected. Among HBV patients, co-infection risk was highest among Asians compared with White race/ethnicity (29.4% vs 5.7%, aOR 4.78; 95% confidence interval [CI], 2.75-8.31), and persons born in a high-incidence country compared with low-incidence countries (31.0% vs 6.6%; aOR 4.19; 95% CI, 2.61-6.73). For patients with latent tuberculosis, risk of co-infection was higher among Asian (aOR 9.99; 95% CI, 5.79-17.20), or Black race/ethnicity (aOR 3.33; 95% CI, 1.78-6.23) compared with White race/ethnicity. Persons born in high-incidence countries had elevated risk of co-infection compared with persons born in low-incidence countries (aOR 2.23; 95% CI, 1.42-3.50). However, Asians or persons born in high-incidence countries were screened at similar rates to other ethnicities or persons born in low-incidence countries. CONCLUSIONS Latent tuberculosis risk is elevated among HBV patients, and vice versa. Risk of co-infection was highest among persons born in high-incidence countries and Asians. These findings support recent guidelines to increase HBV and tuberculosis screening, particularly among persons with either infection.

Abstract
OBJECTIVE The APEX-IUD (Association of Perforation and Expulsion of Intrauterine Devices) study evaluated the association of postpartum timing of intrauterine device (IUD) insertion, breastfeeding, heavy menstrual bleeding, and IUD type (levonorgestrel-releasing vs copper) with risks of uterine perforation and IUD expulsion in usual clinical practice. We summarize the clinically important findings to inform counseling and shared decision making. METHODS APEX-IUD was a real-world (using U.S. health care data) retrospective cohort study of individuals aged 50 years and younger with IUD insertions between 2001 and 2018 and with electronic health record data. Cumulative incidences of uterine perforation and IUD expulsion were calculated. Adjusted hazard ratios (aHRs) and 95% CIs were estimated from proportional hazards models with control of confounding. RESULTS Among the study population of 326,658, absolute risk of uterine perforation was low overall (cumulative incidence, 0.21% [95% CI 0.19-0.23%] at 1 year and 0.61% [95% CI 0.56-0.66% at 5 years]) but was elevated for IUDs inserted during time intervals within 1 year postpartum, particularly among those between 4 days and 6 weeks postpartum (aHR 6.71, 95% CI 4.80-9.38), relative to nonpostpartum insertions. Among postpartum insertions, IUD expulsion risk was greatest for insertions in the immediate postpartum period (0-3 days after delivery) compared with nonpostpartum (aHR 5.34, 95% CI 4.47-6.39). Postpartum individuals who were breastfeeding had a slightly elevated risk of perforation and lowered risk of expulsion than those not breastfeeding. Among nonpostpartum individuals, those with a heavy menstrual bleeding diagnosis were at greater risk of expulsion than those without (aHR 2.84, 95% CI 2.66-3.03); heavy menstrual bleeding also was associated with a slightly elevated perforation risk. There was a slightly elevated perforation risk and slightly lower expulsion risk associated with levonorgestrel-releasing IUDs compared with copper IUDs. CONCLUSION Absolute risk of adverse outcomes with IUD insertion is low. Clinicians should be aware of the differences in risks of uterine perforation and expulsion associated with IUD insertion during specific postpartum time periods and with a heavy menstrual bleeding diagnosis. This information should be incorporated into counseling and decision making for patients considering IUD insertion. FUNDING SOURCE Bayer AG. CLINICAL TRIAL REGISTRATION EU PAS register, EUPAS33461.

Abstract
Background Clinical risk scores were developed to estimate the risk of adult outpatients having a complicated urinary tract infection (cUTI) that was nonsusceptible to trimethoprim-sulfamethoxazole (TMP-SMX), fluoroquinolone, nitrofurantoin, or third-generation cephalosporin (3-GC) based on variables available on clinical presentation. Methods A retrospective cohort study (1 December 2017-31 December 2020) was performed among adult members of Kaiser Permanente Southern California with an outpatient cUTI. Separate risk scores were developed for TMP-SMX, fluoroquinolone, nitrofurantoin, and 3-GC. The models were translated into risk scores to quantify the likelihood of nonsusceptibility based on the presence of final model covariates in a given cUTI outpatient. Results A total of 30 450 cUTIs (26 326 patients) met the study criteria. Rates of nonsusceptibility to TMP-SMX, fluoroquinolone, nitrofurantoin, and 3-GC were 37%, 20%, 27%, and 24%, respectively. Receipt of prior antibiotics was the most important predictor across all models. The risk of nonsusceptibility in the TMP-SMX model exceeded 20% in the absence of any risk factors, suggesting that empiric use of TMP-SMX may not be advisable. For fluoroquinolone, nitrofurantoin, and 3-GC, clinical risk scores of 10, 7, and 11 predicted a ≥20% estimated probability of nonsusceptibility in the models that included cumulative number of prior antibiotics at model entry. This finding suggests that caution should be used when considering these agents empirically in patients who have several risk factors present in a given model at presentation. Conclusions We developed high-performing parsimonious risk scores to facilitate empiric treatment selection for adult outpatients with cUTIs in the critical period between infection presentation and availability of susceptibility results.

Abstract
Abstract
Background
Deleterious outcomes associated with IET are well documented among hospitalized patients with infections. However, scant data exist on the consequences of IET among adult OPs with cUTIs. This study evaluated the association between receipt of IET and 30-day ED/IP visits among adult OPs with cUTIs.
Methods
Retrospective cohort study among Kaiser Permanente Southern California members from 2017-20. Inclusion criteria were age ≥18 years; cUTI diagnosis during an OP visit; positive urine culture with antibiotic (AB) susceptibility results; receipt of AB ±3 days of index urine culture; and not hospitalized on day of OP visit. For OPs with multiple cUTIs, only the index cUTI was considered. IET was defined as failure to receive an AB with in vitro microbiologic activity against all recovered cUTI pathogens ±3 days of culture collection date. Outcomes included all-cause and cUTI-related ED/IP visits ≥3 days to ≤30 days from index culture date. Logistic regression was used to adjust for baseline differences between appropriateness groups.
Results
During study period, 25,980 OPs with cUTIs met study criteria. Mean age was 60 years, majority female (57%), and E. coli (66%) was the most common pathogen. IET was noted in 2656 (10%) of patients. Comparison of baseline characteristics between appropriateness groups is shown in Table. Comparison of 30-day all-cause and cUTI-related ED/IP visits between IET and appropriate empiric therapy (AET) is shown in Figure. In the logistic regression, receipt of IET was associated with an increase odds of 30-day all-cause ED/IP visits (adjusted odds ratio (aOR)= 1.3; 95% CI: 1.2-1.4) and 30-day cUTI-related ED/IP visits (aOR=1.5; 95% CI: 1.4-1.7), respectively. Figure
Conclusion
Thirty-day all-cause and cUTI-related ED/IP visits were significantly higher among adult OPs with cUTI who received IET. As culture and susceptibility results are frequently unknown at the time of empiric therapy selection, the findings highlight the critical need to use institution-specific antibiotic resistance risk stratification tools, in tandem with rapid diagnostic tests, to guide empiric antibiotic decisions among OPs with cUTIs as measures to ensure patients receive AET and maximize chances of a successful clinical outcome.

Abstract
Abstract
Background
Increased resistance rates to available oral antibiotics (ABs) contribute to delays in receipt of appropriate treatment and adverse outcomes among patients with cUTI in the OP setting. To optimize empiric AB selection in adult OPs with cUTIs, we developed CRSs using information available at presentation to estimate the risk of having a cUTI that was resistant to TMP-SMX, FQ, NIT, or 3GC.
Methods
Retrospective cohort study among Kaiser Permanente Southern California members from 2017-2020. Inclusion criteria: age ≥18 yrs; cUTI diagnosis during an OP visit; positive urine culture with antibiotic susceptibility results; receipt of antibiotic ±3 days of index urine culture, and not hospitalized on day of OP visit. Resistance to TMP-SMX, FQ, NIT, and 3GC on index urine culture was quantified. OPs were randomly split (60:40) into training and validation datasets. Covariates present on clinical presentation were collected. Least absolute shrinkage and selection operator logistic regression (LR) were used to develop separate models to estimate the likelihood of resistance to TMP-SMX, FQ, NIT, and 3GC. The prediction models were developed using training and validation datasets. For all 4 LR models, CRSs were calculated as the weighted sums of regression coefficients. Variables in each of the final LR models were assigned point(s), and an OP’s CRS for cUTI resistant to TMP-SMX, FQ, NIT, or 3GC was based on total points in each of the respective models.
Results
A total of 30,450 cUTIs among 26,326 OPs met study criteria. Mean age was 61, 54% were female, and E. coli (66%) was the most common pathogen. Resistance to TMP-SMX, FQ, NIT, and 3GC was 37%, 27%, 24%, and 19%, respectively. Baseline covariates and associated points for the 4 LR models are shown in Table 1. A CRS of 0, 5, 8, 12 corresponded to a >20% risk of resistance to TMP-SMX, FQ, NIT, or 3GC, respectively (Figure 1). Table 1.Baseline Clinical Covariates and Associated Point Values in Each of the 4 Clinical Risk Scores Covariates in each of the Final ResistanceFigure 1.Clinical Risk Scores for Resistance to TMP-SMX, FQ, NIT, and 3GC
Conclusion
We developed a high-performing parsimonious CRS to aid clinicians in appropriate treatment selection of adult OPs with cUTI. This tool can be used to facilitate empiric antibiotic selection and ensure adult OPs with cUTI have a greater probability of receiving early appropriate therapy. Given its high baseline resistance, TMP/SMX should not be considered for empiric therapy.

Abstract
PURPOSE The 'DSD Pathways' study was initiated to assess health status and patterns of care among people enrolled in large integrated healthcare systems and diagnosed with conditions comprising the broad category of disorders (differences) of sex development (DSD). The objectives of this communication are to describe methods of cohort ascertainment for two specific DSD conditions-classic congenital adrenal hyperplasia with 46,XX karyotype (46,XX CAH) and complete androgen insensitivity syndrome (CAIS). PARTICIPANTS Using electronic health records we developed an algorithm that combined diagnostic codes, clinical notes, laboratory data and pharmacy records to assign each cohort candidate a 'strength-of-evidence' score supporting the diagnosis of interest. A sample of cohort candidates underwent a review of the full medical record to determine the score cutoffs for final cohort validation. FINDINGS TO DATE Among 5404 classic 46,XX CAH cohort candidates the strength-of-evidence scores ranged between 0 and 10. Based on sample validation, the eligibility cut-off for full review was set at the strength-of-evidence score of ≥7 among children under the age of 8 years and ≥8 among older cohort candidates. The final validation of all cohort candidates who met the cut-off criteria identified 115 persons with classic 46,XX CAH. The strength-of-evidence scores among 648 CAIS cohort candidates ranged from 2 to 10. There were no confirmed CAIS cases among cohort candidates with scores <6. The in-depth medical record review for candidates with scores ≥6 identified 61 confirmed cases of CAIS. FUTURE PLANS As the first cohort of this type, the DSD Pathways study is well-positioned to fill existing knowledge gaps related to management and outcomes in this heterogeneous population. Analyses will examine diagnostic and referral patterns, adherence to care recommendations and physical and mental health morbidities examined through comparisons of DSD and reference populations and analyses of health status across DSD categories.

Abstract
BACKGROUND Intrauterine devices, including levonorgestrel-releasing and copper devices, are highly effective long-acting reversible contraceptives. The potential risks associated with intrauterine devices are low and include uterine perforation and device expulsion. OBJECTIVE This study aimed to evaluate the risk of perforation and expulsion associated with levonorgestrel-releasing devices vs copper devices in clinical practice in the United States. STUDY DESIGN The Association of Perforation and Expulsion of Intrauterine Devices study was a retrospective cohort study of women aged ≤50 years with an intrauterine device insertion during 2001 to 2018 and information on intrauterine device type and patient and medical characteristics. Of note, 4 research sites with access to electronic health records contributed data for the study: 3 Kaiser Permanente-integrated healthcare systems (Northern California, Southern California, and Washington) and 1 healthcare system using data from a healthcare information exchange in Indiana (Regenstrief Institute). Perforation was classified as any extension of the device into or through the myometrium. Expulsion was classified as complete (not visible in the uterus or abdomen or patient reported) or partial (any portion in the cervix or malpositioned). We estimated the crude incidence rates and crude cumulative incidence by intrauterine device type. The risks of perforation and expulsion associated with levonorgestrel-releasing intrauterine devices vs copper intrauterine devices were estimated using Cox proportional-hazards regression with propensity score overlap weighting to adjust for confounders. RESULTS Among 322,898 women included in this analysis, the incidence rates of perforation per 1000 person-years were 1.64 (95% confidence interval, 1.53-1.76) for levonorgestrel-releasing intrauterine devices and 1.27 (95% confidence interval, 1.08-1.48) for copper intrauterine devices; 1-year and 5-year crude cumulative incidence was 0.22% (95% confidence interval, 0.20-0.24) and 0.63% (95% confidence interval, 0.57-0.68) for levonorgestrel-releasing intrauterine devices and 0.16% (95% confidence interval, 0.13-0.20) and 0.55% (95% confidence interval, 0.44-0.68) for copper intrauterine devices, respectively. The incidence rates of expulsion per 1000 person-years were 13.95 (95% confidence interval, 13.63-14.28) for levonorgestrel-releasing intrauterine devices and 14.08 (95% confidence interval, 13.44-14.75) for copper intrauterine devices; 1-year and 5-year crude cumulative incidence was 2.30% (95% confidence interval, 2.24-2.36) and 4.52% (95% confidence interval, 4.40-4.65) for levonorgestrel-releasing intrauterine devices and 2.30% (95% confidence interval, 2.18-2.44) and 4.82 (95% confidence interval, 4.56-5.10) for copper intrauterine devices, respectively. Comparing levonorgestrel-releasing intrauterine devices with copper intrauterine devices, the adjusted hazard ratios were 1.49 (95% confidence intervals, 1.25-1.78) for perforation and 0.69 (95% confidence intervals, 0.65-0.73) for expulsion. CONCLUSION After adjusting for potential confounders, levonorgestrel-releasing intrauterine devices were associated with an increased risk of uterine perforation and a decreased risk of expulsion relative to copper intrauterine devices. Given that the absolute numbers of these events are low in both groups, these differences may not be clinically meaningful.

Abstract
BACKGROUND Intrauterine devices are effective instruments for contraception, and 1 levonorgestrel-releasing device is also indicated for the treatment of heavy menstrual bleeding (menorrhagia). OBJECTIVE To compare the incidence of intrauterine device expulsion and uterine perforation in women with and without a diagnosis of menorrhagia within the first 12 months before device insertion STUDY DESIGN: This was a retrospective cohort study conducted in 3 integrated healthcare systems (Kaiser Permanente Northern California, Southern California, and Washington) and a healthcare information exchange (Regenstrief Institute) in the United States using electronic health records. Nonpostpartum women aged ≤50 years with intrauterine device (eg, levonorgestrel or copper) insertions from 2001 to 2018 and without a delivery in the previous 12 months were studied in this analysis. Recent menorrhagia diagnosis (ie, recorded ≤12 months before insertion) was ascertained from the International Classification of Diseases, Ninth and Tenth Revision, Clinical Modification codes. The study outcomes, viz, device expulsion and device-related uterine perforation (complete or partial), were ascertained from electronic medical records and validated in the data sources. The cumulative incidence and crude incidence rates with 95% confidence intervals were estimated. Cox proportional hazards models estimated the crude and adjusted hazard ratios using propensity score overlap weighting (13-16 variables) and 95% confidence intervals. RESULTS Among 228,834 nonpostpartum women, the mean age was 33.1 years, 44.4% of them were White, and 31,600 (13.8%) had a recent menorrhagia diagnosis. Most women had a levonorgestrel-releasing device (96.4% of those with and 78.2% of those without a menorrhagia diagnosis). Women with a menorrhagia diagnosis were likely to be older, obese, and have dysmenorrhea or fibroids. Women with a menorrhagia diagnosis had a higher intrauterine device-expulsion rate (40.01 vs 10.92 per 1000 person-years) than those without, especially evident in the first few months after insertion. Women with a menorrhagia diagnosis had a higher cumulative incidence (95% confidence interval) of expulsion (7.00% [6.70-7.32] at 1 year and 12.03% [11.52-12.55] at 5 years) vs those without (1.77% [1.70-1.84] at 1 year and 3.69% [3.56-3.83] at 5 years). The risk of expulsion was increased for women with a menorrhagia diagnosis vs for those without (adjusted hazard ratio, 2.84 [95% confidence interval, 2.66-3.03]). The perforation rate was low overall (<1/1000 person-years) but higher in women with a diagnosis of menorrhagia vs in those without (0.98 vs 0.63 per 1000 person-years). The cumulative incidence (95% confidence interval) of uterine perforation was slightly higher for women with a menorrhagia diagnosis (0.09% [0.06-0.14] at 1 year and 0.39% [0.29-0.53] at 5 years) than those without it (0.07% [0.06-0.08] at 1 year and 0.28% [0.24-0.33] at 5 years). The risk of perforation was slightly increased in women with a menorrhagia diagnosis vs in those without (adjusted hazard ratio, 1.53; 95% confidence interval, 1.10-2.13). CONCLUSION The risk of expulsion is significantly higher in women with a recent diagnosis of menorrhagia. Patient education and counseling regarding the potential expulsion risk is recommended at insertion. The absolute risk of perforation for women with a recent diagnosis of menorrhagia is very low. The increased expulsion and perforation rates observed are likely because of causal factors of menorrhagia.

Abstract
IMPORTANCE Intrauterine device (IUD) expulsion increases the risk of unintended pregnancy; how timing of postpartum IUD insertion and breastfeeding are associated with risk of expulsion is relevant to the benefit-risk profile. OBJECTIVE To evaluate the association of postpartum timing of IUD insertion and breastfeeding status with incidence and risk of IUD expulsion. DESIGN, SETTING, AND PARTICIPANTS The Association of Perforation and Expulsion of Intrauterine Devices (APEX-IUD) cohort study included women aged 50 years or younger with an IUD insertion between 2001 and 2018. The breastfeeding analysis focused on a subcohort of women at 52 or fewer weeks post partum with known breastfeeding status. The study was conducted using data from electronic health records (EHRs) at 4 research sites with access to EHR: 3 Kaiser Permanente sites (Northern California, Southern California, Washington) and the Regenstrief Institute (Indiana). Data analysis was conducted from June to November 2019. EXPOSURES Timing of IUD insertion post partum was categorized into discrete time periods: 0 to 3 days, 4 days to 6 or fewer weeks, more than 6 weeks to 14 or fewer weeks, more than 14 weeks to 52 or fewer weeks, and non-post partum (>52 weeks or no evidence of delivery). Breastfeeding status at the time of insertion was determined from clinical records, diagnostic codes, or questionnaires from well-baby visits. MAIN OUTCOMES AND MEASURES Incidence rates and adjusted hazard ratios (aHRs) were estimated using propensity scores to adjust for confounding. RESULTS The full cohort included 326 658 women (mean [SD] age, 32.0 [8.3] years; 38 911 [11.9%] Asian or Pacific Islander; 696 [0.2%] Hispanic Black; 56 180 [17.2%] Hispanic other; 42 501 [13.0%] Hispanic White; 28 323 [8.7%] non-Hispanic Black; 137 102 [42.0%] non-Hispanic White), and the subcohort included 94 817 women. Most IUDs were levonorgestrel-releasing (259 234 [79.4%]). There were 8943 expulsions. The 5-year cumulative incidence of IUD expulsion was highest for insertions 0 to 3 days post partum (10.73%; 95% CI, 9.12%-12.61%) and lowest for insertions more than 6 weeks to 14 or fewer weeks post partum (3.18%; 95% CI, 2.95%-3.42%). Adjusted HRs using women with non-post partum IUD insertion as the referent were 5.34 (95% CI, 4.47-6.39) for those with postpartum insertion at 0 to 3 days; 1.22 (95% CI, 1.05-1.41) for those with postpartum insertion at 4 days to 6 or fewer weeks; 1.06 (95% CI, 0.95-1.18) for those with postpartum insertion at more than 6 to 14 or fewer weeks; and 1.43 (95% CI, 1.29-1.60) for those with postpartum insertion at more than 14 to 52 or fewer weeks. In the subcohort, 5-year cumulative incidence was 3.49% (95% CI, 3.25%-3.73%) for breastfeeding women and 4.57% (95% CI, 4.22%-4.95%) for nonbreastfeeding women; the adjusted HR for breastfeeding vs not breastfeeding was 0.71 (95% CI, 0.64-0.78). CONCLUSIONS AND RELEVANCE In this study of real-world data, IUD expulsion was rare but more common with immediate postpartum insertion. Breastfeeding was associated with lower expulsion risk.

Abstract
Background It is estimated that there are 1.59 million cases of chronic hepatitis B virus (HBV) infection (CHB) in the United States. HBV infection is highest among men and non-Hispanic Asian adults. CHB can lead to liver damage, cirrhosis, hepatocellular carcinoma, or death. However, the population that is most likely to develop severe outcomes is not as well-defined. Methods We evaluated electronic health record data from Kaiser Permanente Southern California adult members from 2008-2019 with at least 1 year of continuous membership, and with 2 successive, positive HBV lab results (HBV DNA, or HBsAg, or HBeAg) at least 6 months apart (indicative of CHB). Severe outcomes included incident hepatic decompensation, hepatocellular carcinoma (HCC), liver transplant and death, and prevalent and incident liver cirrhosis. For each outcome, we estimated the distribution of characteristics including age, sex, race/ethnicity, and lab values (alanine aminotransferase [ALT], alpha-fetoprotein [AFP], MELD score). Results Our final study population included 5,427 CHB-diagnosed patients with 411 (7.6%) cases of liver cirrhosis, 123 (2.3%) of hepatic decompensation, 65 (1.2%) of HCC, 8 (0.1%) of liver transplant, and 164 (3.0%) deaths. Compared to the total cohort, those who developed severe outcomes were older (median age for each outcome >50 years vs. 47 years in total CHB population). Among those with severe outcomes, the majority were male ( >56%) and Asian. Diabetes was more prevalent in patients with hepatic decompensation, HCC, and death versus the entire cohort (25% vs. 8%, respectively, P< 0.0001), and twice as prevalent among those with cirrhosis. All severe outcomes were associated with >2 x upper limit of normal ALT levels. Conclusion The characteristics of those with severe outcomes were consistent with those of overall CHB, although there was a 2-3 times higher prevalence of diabetes in those with severe outcomes. Identifying characteristics that are more prevalent in those with severe outcomes can help inform screening and management of CHB. Disclosures Ana Florea, PhD MPH, Gilead Inc.

Abstract
STUDY OBJECTIVES The most commonly prescribed antibiotics for patients with hospital-acquired bacterial pneumonia (HABP) and ventilator-associated bacterial pneumonia (VABP) due to Pseudomonas aeruginosa are the conventional anti-pseudomonal β-lactams (APBLs) (ie, ceftazidime, cefepime, meropenem, or piperacillin-tazobactam). Similar resistance mechanisms in P. aeruginosa affect the APBLs, and it is unclear if resistance to one APBL can affect the effectiveness of other APBLs. This exploratory, hypothesis-generating analysis evaluates the impact of APBL resistance among patients in the intensive care unit (ICU) with P. aeruginosa HABP/VABP who initially receive a microbiologically active APBL. DESIGN A retrospective cohort [GJ1] [LT2] study. SETTING Kaiser Permanente Southern California members (01/01/2011-12/31/2017). PATIENTS The study included adult patients admitted to the ICU with a monomicrobial P. aeruginosa HABP/VABP who received a microbiologically active APBL within 2 days of index P. aeruginosa respiratory culture. INTERVENTION Patients were stratified by presence of resistance to APBL on index P. aeruginosa (0 vs. ≥1 resistant APBL). MEASUREMENTS Primary outcomes were 30-day mortality and discharge to home. MAIN RESULTS Overall, 553 patients were included. Thirty-day mortality was 28%, and 32% of patients were discharged home. Eighty-eight patients (16%) had a P. aeruginosa HABP/VABP that was resistant to ≥1 APBL (other than active empiric treatment). Relative to patients with no APBL resistance, patients with resistance to ≥1 APBL had a higher 30-day mortality (adjusted odds ratio (aOR) [95% confidence interval (CI)]: 1.65 [1.02-2.66]) and were less likely to be discharged home (adjusted hazard ratio (aHR) [95% CI]: 0.50 [0.29-0.85]). CONCLUSION Further study is needed, but this exploratory analysis suggests that the full APBL susceptibility profile should be considered when selecting therapy for patients with P. aeruginosa HABP/VABP.

Abstract
BACKGROUND Intrauterine devices are effective and safe, long-acting reversible contraceptives, but the risk of uterine perforation occurs with an estimated incidence of 1 to 2 per 1000 insertions. The European Active Surveillance Study for Intrauterine Devices, a European prospective observational study that enrolled 61,448 participants (2006-2012), found that women breastfeeding at the time of device insertion or with the device inserted at ≤36 weeks after delivery had a higher risk of uterine perforation. The Association of Uterine Perforation and Expulsion of Intrauterine Device (APEX-IUD) study was a Food and Drug Administration-mandated study designed to reflect current United States clinical practice. The aims of the APEX-IUD study were to evaluate the risk of intrauterine device-related uterine perforation and device expulsion among women who were breastfeeding or within 12 months after delivery at insertion. OBJECTIVE We aimed to describe the APEX-IUD study design, methodology, and analytical plan and present population characteristics, size of risk factor groups, and duration of follow-up. STUDY DESIGN APEX-IUD study was a retrospective cohort study conducted in 4 organizations with access to electronic health records: Kaiser Permanente Northern California, Kaiser Permanente Southern California, Kaiser Permanente Washington, and Regenstrief Institute in Indiana. Variables were identified through structured data (eg, diagnostic, procedural, medication codes) and unstructured data (eg, clinical notes) via natural language processing. Outcomes include uterine perforation and device expulsion; potential risk factors were breastfeeding at insertion, postpartum timing of insertion, device type, and menorrhagia diagnosis in the year before insertion. Covariates include demographic characteristics, clinical characteristics, and procedure-related variables, such as difficult insertion. The first potential date of inclusion for eligible women varies by research site (from January 1, 2001 to January 1, 2010). Follow-up begins at insertion and ends at first occurrence of an outcome of interest, a censoring event (device removal or reinsertion, pregnancy, hysterectomy, sterilization, device expiration, death, disenrollment, last clinical encounter), or end of the study period (June 30, 2018). Comparisons of levels of exposure variables were made using Cox regression models with confounding adjusted by propensity score weighting using overlap weights. RESULTS The study population includes 326,658 women with at least 1 device insertion during the study period (Kaiser Permanente Northern California, 161,442; Kaiser Permanente Southern California, 123,214; Kaiser Permanente Washington, 20,526; Regenstrief Institute, 21,476). The median duration of continuous enrollment was 90 (site medians 74-177) months. The mean age was 32 years, and the population was racially and ethnically diverse across the 4 sites. The mean body mass index was 28.5 kg/m2, and of the women included in the study, 10.0% had menorrhagia ≤12 months before insertion, 5.3% had uterine fibroids, and 10% were recent smokers; furthermore, among these women, 79.4% had levonorgestrel-releasing devices, and 19.5% had copper devices. Across sites, 97,824 women had an intrauterine device insertion at ≤52 weeks after delivery, of which 94,817 women (97%) had breastfeeding status at insertion determined; in addition, 228,834 women had intrauterine device insertion at >52 weeks after delivery or no evidence of a delivery in their health record. CONCLUSION Combining retrospective data from multiple sites allowed for a large and diverse study population. Collaboration with clinicians in the study design and validation of outcomes ensured that the APEX-IUD study results reflect current United States clinical practice. Results from this study will provide valuable information based on real-world evidence about risk factors for intrauterine devices perforation and expulsion for clinicians.

Abstract
BACKGROUND Duration and number of power outages have increased over time, partly fueled by climate change, putting users of electricity-dependent durable medical equipment (hereafter, "durable medical equipment") at particular risk of adverse health outcomes. Given health disparities in the United States, we assessed trends in durable medical equipment rental prevalence and individual- and area-level sociodemographic inequalities. METHODS Using Kaiser Permanente South California electronic health record data, we identified durable medical equipment renters. We calculated annual prevalence of equipment rental and fit hierarchical generalized linear models with ZIP code random intercepts, stratified by rental of breast pumps or other equipment. RESULTS 243,559 KPSC members rented durable medical equipment between 2008 and 2018. Rental prevalence increased over time across age, sex, racial-ethnic, and Medicaid categories, most by >100%. In adjusted analyses, Medicaid use was associated with increased prevalence and 108 (95% confidence interval [CI] = 99, 117) additional days of equipment rental during the study period. ZIP code-level sociodemographics were associated with increased prevalence of equipment rentals, for example, a 1 SD increase in percent unemployed and CONCLUSIONS We observed some socioeconomic disparities among a growing electricity-dependent population. Our findings are consistent with the hypothesis that reliable electricity access is increasingly required to meet the health needs of medically disadvantaged groups.

Abstract
Background The most commonly prescribed antibiotics for PSA HAP/VAP are ASPBs: meropenem (MER), piperacillin/tazobactam (TZP),cefepime (FEP) and ceftazidime (CAZ). Similar resistance mechanisms in PSA affect these agents, and it is unclear if you can use a susceptible ASPB when the PSA is resistant to other ASPBs. This study evaluates the impact of ASPB resistance among pts with PSA HAP/VAP who initially received therapy with an ASPB to which PSA was susceptible. Methods A cohort study of Kaiser Permanente Southern California (KPSC) members (1/1/11-12/31/17) was performed. Inclusion criteria: (1) age ≥ 18 years; (2) HAP/VAP diagnosis; (3) monomicrobial PSA on a clinical respiratory culture (index PSA); (4) ICU at index PSA; (5) received MER, TZP, FEP or CAZ within ≤ 2 days of index PSA; (6) index PSA was susceptible to ASPB received; (7) no cystic fibrosis; (8) survived > 2 days post index PSA, and (9) ≥ 6 months of KPSC membership prior to index PSA. Pts were stratified by presence of resistance to MER, TZP, and FEP on index PSA (0 vs. ≥1 resistant ASPB). Outcomes: 30-day mortality and discharge to home. Results 560 patients were included. Mean (SD) age was 70.5 (14.2) years, 60% were male, and most had many comorbidities. Thirty-day mortality was 28%, and 32% were discharged home. Ninety-five (17%) received an active ASPB for PSA HAP/VAP that was resistance to ≥ 1 ASPB. Relative to pts with no ASPB resistance, pts with resistance ≥ 1 ASPB had higher 30-day mortality (32% vs. 27%) and were less likely to be discharged home (17% vs. 35%). In multivariate analyses, pts with resistance ≥ 1 ASPB had higher 30-day mortality (aOR=1.61 [CI: 1.01-2.56]) and were less likely to be discharged home (aHR [95%]: 0.5 [0.3-0.9]). Crude and Adjusted Associations Between Presence of Anti-Pseudomonal β-Lactam -Resistance (Reference= no ASPB resistance) and Outcomes among Adult, ICU patients with HAP/VAP due to PSA who received a Microbiologic Active Anti-Pseudomonal β-Lactam ![]()
Conclusion Despite receiving a microbiologic active agent within ≤ 2 days of their PSA HAP/VAP, pts with PSA that were resistant to ≥ 1 ASPB had worse outcomes relative to those that had no ASPB resistance. Further study is needed, but these findings suggest that the full ASPB susceptibility profile needs to be considered when selecting therapy for pts with PSA HAP/VAP. More studies are also needed to determine if alternative or combination therapies may be needed to maximize outcomes in PSA infection when there is resistance ≥ 1 ASPB.

Abstract
BACKGROUND Surveillance of ectopic pregnancy (EP) using electronic databases is important. To our knowledge, no published study has assessed the validity of EP case ascertainment using electronic health records. OBJECTIVE We aimed to assess the validity of an enhanced version of a previously validated algorithm, which used a combination of encounters with EP-related diagnostic/procedure codes and methotrexate injections. METHODS Medical records of 500 women aged 15-44 years with membership at Kaiser Permanente Southern and Northern California between 2009 and 2018 and a potential EP were randomly selected for chart review, and true cases were identified. The enhanced algorithm included diagnostic/procedure codes from the International Classification of Diseases, Tenth Revision, used telephone appointment visits, and excluded cases with only abdominal EP diagnosis codes. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall performance (Youden index and F-score) of the algorithm were evaluated and compared to the validated algorithm. RESULTS There were 334 true positive and 166 true negative EP cases with available records. True positive and true negative EP cases did not differ significantly according to maternal age, race/ethnicity, and smoking status. EP cases with only one encounter and non-tubal EPs were more likely to be misclassified. The sensitivity, specificity, PPV, and NPV of the enhanced algorithm for EP were 97.6%, 84.9%, 92.9%, and 94.6%, respectively. The Youden index and F-score were 82.5% and 95.2%, respectively. The sensitivity and NPV were lower for the previously published algorithm at 94.3% and 88.1%, respectively. The sensitivity of surgical procedure codes from electronic chart abstraction to correctly identify surgical management was 91.9%. The overall accuracy, defined as the percentage of EP cases with correct management (surgical, medical, and unclassified) identified by electronic chart abstraction, was 92.3%. CONCLUSIONS The performance of the enhanced algorithm for EP case ascertainment in integrated health care databases is adequate to allow for use in future epidemiological studies. Use of this algorithm will likely result in better capture of true EP cases than the previously validated algorithm.

Abstract
Accurate identification of transgender persons is a critical first step in conducting transgender health studies. To develop an automated algorithm for identifying transgender individuals from electronic medical records (EMR) using free-text clinical notes. The development and validation of the algorithm was based on data from an integrated healthcare system that served as a participating site in the multicenter Study of Transition Outcomes and Gender. The training and test datasets each contained a total of 300 individuals identified between 2006 and 2014. Both datasets underwent a full medical record review by experienced research abstractors. The validated algorithm was then implemented to identify transgender individuals in the EMR using all clinical notes of patients that received care between January 1, 2015 and June 30, 2018. Validation of the algorithm against the full chart review demonstrated a high degree of accuracy with 97% sensitivity, 95% specificity, 94% positive predictive value, and 97% negative predictive value. The algorithm classified 7,409 individuals (3.5%) as "Definitely transgender" and 679 individuals (0.3%) as "Probably transgender" out of 212,138 candidates with a total of 378,641 clinical notes. The computerized NLP algorithm can support essential efforts to improve the health of transgender people.

Abstract
Objective To validate algorithms identifying uterine perforations and intrauterine device (IUD) expulsions and to ascertain availability of breastfeeding status at the time of IUD insertion. Study design and setting Four health care systems with electronic health records (EHRs) participated: Kaiser Permanente Northern California (KPNC), Kaiser Permanente Southern California (KPSC), Kaiser Permanente Washington (KPWA), and Regenstrief Institute (RI). The study included women ≤50 years of age with an IUD insertion. Site-specific algorithms using structured and unstructured data were developed and a sample validated by EHR review. Positive predictive values (PPVs) of the algorithms were calculated. Breastfeeding status was assessed in a random sample of 125 women at each research site with IUD placement within 52 weeks postpartum. Results The study population included 282,028 women with 325,582 IUD insertions. The PPVs for uterine perforation were KPNC 77%, KPSC 81%, KPWA 82%, and RI 47%; PPVs for IUD expulsion were KPNC 77%, KPSC 87%, KPWA 68%, and RI 37%. Across all research sites, breastfeeding status at the time of IUD insertion was determined for 94% of those sampled. Conclusions Algorithms with a high PPV for uterine perforation and IUD expulsion were developed at 3 of the 4 research sites. Breastfeeding status at the time of IUD insertion could be determined at all research sites. Our findings suggest that a study to evaluate the associations of breastfeeding and postpartum IUD insertions with risk of uterine perforation and IUD expulsion can be successfully conducted retrospectively; however, automated application of algorithms must be supplemented with chart review for some outcomes at one research site due to low PPV.

Abstract
IMPORTANCE Treatment of patients with infections due to Pseudomonas aeruginosa has been complicated by increased antibiotic resistance rates, which contribute to delayed appropriate treatment and deleterious outcomes. OBJECTIVE To develop 2 clinical risk scores based on variables available at clinical presentation to estimate the risk of carbapenem resistance (CR) or extensive β-lactam resistance (EBR) among hospitalized, adult patients with P aeruginosa infections. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study included adult (age, ≥18 years) members of Kaiser Permanente Southern California (KPSC) with a P aeruginosa infection during hospitalization from September 1, 2011, through August 31, 2016, who received antibiotic therapy within 2 days of the culture date. Data were analyzed from July 2, 2017, through August 15, 2018. EXPOSURES Demographic, clinical, and laboratory covariates 1 year before the index culture date were evaluated. MAIN OUTCOMES AND MEASURES Pseudomonas aeruginosa was categorized as antibiotic susceptible, CR, or EBR (nonsusceptibility to carbapenems, ceftazidime, and combined piperacillin sodium and tazobactam sodium). Patients were randomly split (1:1) into training and validation data sets. The training data set was used to develop 2 prediction models using high-performance logistic regression with variable selection by Schwarz-Bayesian criterion. The models were translated into risk scores, with risk score points equaling the weighted sums of regression coefficients from the prediction model. The patient's risk was estimated as the inverse logit of the risk score. RESULTS Of the 7775 patients with 11 502 P aeruginosa infections included in the analysis, most were male (4308 [55.4%]) and non-Hispanic white (3927 [50.5%]). The mean (SD) age was 70.3 (15.5) years. Among 11 502 P aeruginosa infections, 2324 (20.2%) were CR, 9178 (79.8%) were non-CR, 1033 (9.0%) were EBR, and 10 469 were non-EBR (91.0%). The strongest predictors of resistance in the CR and EBR models were history of CR P aeruginosa infection (odds ratios [ORs], 8.80 [95% CI, 6.74-11.49] and 5.04 [95% CI, 3.88-6.54], respectively), tracheostomy (ORs, 3.49 [95% CI, 2.92-4.16] and 3.13 [95% CI, 2.50-3.91], respectively), and carbapenem use in the prior 30 days (ORs, 4.18 [95% CI, 3.29-5.31] and 2.26 [95% CI, 1.74-2.93], respectively). The models for CR and EBR performed well, with areas under the receiver operating characteristics curve of 0.81 or greater for the training and validation data sets. CONCLUSIONS AND RELEVANCE The findings of this study suggest that parsimonious risk scores can aid physicians in appropriate treatment selection during the critical period when P aeruginosa infection is suspected but antibiotic susceptibility results are not yet available.

Abstract
OBJECTIVE The Advisory Committee on Immunization Practices recommends Hepatitis B (HepB) vaccine for previously unvaccinated adults <60 years with diabetes mellitus. This observational retrospective cohort study assessed the impact of implementing electronic provider reminders on HepB vaccine initiation and 3-dose series completion rates among insured adults with diabetes aged 19-59 years old. RESEARCH DESIGN AND METHODS Difference-in-difference (DID) analyses compared changes in vaccine initiation and completion rates (ratio of the rate ratio [RRR] and 95% confidence interval [CI]) during 12 months pre- and post-implementation between intervention and control sites. We examined trends in vaccine initiation and completion rates by plotting monthly rates during the study period. We also calculated the overall HepB vaccine coverage rates with 95% CI among all adults with diabetes aged 19-59 years old at the start and end date of the study period. RESULTS Baseline HepB vaccine initiation and completion rates were similar at both the intervention and control sites. Gender, age, and race/ethnicity distributions within both sites were similar during the 12 months pre- and post-implementation. DID analyses demonstrated statistically significant differences in the changes of the annual vaccine initiation rates (RRR: 70.7, 95% CI: 62.8-79.6) and the third dose completion rates (RRR = 18.7, 95% CI: 14.2-24.8) between the two sites. The coverage increased significantly at the intervention site while it remained low at the control site. CONCLUSIONS Use of provider reminders is highly effective in increasing both HepB vaccine initiation and series completion rates among adults with diabetes.
