RESUMO

PURPOSE: Compare occurrence of self-inflicted injuries among transgender and gender diverse (TGD) youth to that of their cisgender peers while accounting for mental health diagnoses. METHODS: Review of electronic health records from three integrated health care systems identified 1087 transfeminine and 1431 transmasculine adolescents and young adults. Poisson regression was used to calculate prevalence ratios comparing the proportion of TGD participants with at least one self-inflicted injury (a surrogate for suicide attempt) before index date (first evidence of TGD status) to the corresponding proportions in presumed cisgender male and female referents matched on age, race/ethnicity, and health plan. Interactions between gender identities and mental health diagnoses were assessed on multiplicative and additive scales. RESULTS: TGD adolescents and young adults were more likely to have a self-inflicted injury, various mental health diagnoses, and multiple mental health diagnoses than their cisgender peers. The prevalence of self-inflicted injuries among TGD adolescents and young adults was high even in the absence of mental health diagnoses. Results were consistent with positive additive interaction and negative multiplicative interaction. CONCLUSIONS: Universal suicide prevention efforts for all youth, including those with no mental health diagnoses, and more intensive suicide prevention efforts for TGD adolescents and young adults and those with at least one mental health diagnosis are warranted.

RESUMO

BACKGROUND: The delivery of adult primary care (APC) shifted from predominately in-person to modes of virtual care during the COVID-19 pandemic. It is unclear how these shifts impacted the likelihood of APC use during the pandemic, or how patient characteristics may be associated with the use of virtual care. METHODS: A retrospective cohort study using person-month level datasets from 3 geographically disparate integrated health care systems was conducted for the observation period of January 1, 2020, through June 30, 2021. We estimated a 2-stage model, first adjusting for patient-level sociodemographic, clinical, and cost-sharing factors, using generalized estimating equations with a logit distribution, along with a second-stage multinomial generalized estimating equations model that included an inverse propensity score treatment weight to adjust for the likelihood of APC use. Factors associated with APC use and virtual care use were separately assessed for the 3 sites. RESULTS: Included in the first-stage models were datasets with total person-months of 7,055,549, 11,014,430, and 4,176,934, respectively. Older age, female sex, greater comorbidity, and Black race and Hispanic ethnicity were associated with higher likelihood of any APC use in any month; measures of greater patient cost-sharing were associated with a lower likelihood. Conditional on APC use, older age, and adults identifying as Black, Asian, or Hispanic were less likely to use virtual care. CONCLUSIONS: As the transition in health care continues to evolve, our findings suggest that to ensure vulnerable patient groups receive high quality health care, outreach interventions to reduce barriers to virtual care use may be warranted.

RESUMO

BACKGROUND: During the COVID-19 pandemic, more health care issues were being managed remotely. Urinary tract infections (UTIs) are being managed more often using telehealth although few reports compare the rate of UTI ancillary service orders placed and fulfilled during these visits. OBJECTIVES: We aimed to evaluate and compare the rate of ancillary service orders and order fulfillments in incident UTI diagnoses between virtual and in-person encounters. RESEARCH DESIGN: The retrospective cohort study involved 3 integrated health care systems: Kaiser Permanente (KP) Colorado, KP Georgia, and KP Mid-Atlantic States. SUBJECTS: We included incident UTI encounters from adult primary care data from January 2019 to June 2021. MEASURES: Data were categorized as: prepandemic (January 2019-March 2020), COVID-19 Era 1 (April 2020-June 2020), and COVID-19 Era 2 (July 2020-June 2021). UTI-specific ancillary services included medication, laboratory, and imaging. Orders and order fulfillments were dichotomized for analyses. Weighted percentages for orders and fulfillments were calculated using inverse probability treatment weighting from logistic regression and compared between virtual and in-person encounters using χ2 tests. RESULTS: We identified 123,907 incident encounters. Virtual encounters increased from 13.4% prepandemic to 39.1% in COVID-19 Era 2. Ancillary service orders from virtual encounters were not placed as often as in-person encounters. However, the weighted percentage for ancillary service order fulfillment across all services remained above 65.3% across sites and eras, with many fulfillment percentages above 90%. CONCLUSIONS: Our study reported a high rate of order fulfillment for both virtual and in-person encounters. Health care systems should encourage providers to place ancillary service orders for uncomplicated diagnoses, such as UTI, to provide enhanced access to patient-centered care.

RESUMO

BACKGROUND: The abrupt shift to virtual care at the onset of the COVID-19 pandemic had the potential to disrupt care practices in virtual behavioral health encounters. We examined changes over time in virtual behavioral health-care-related practices for patient encounters with diagnoses of major depression. METHODS: This retrospective cohort study utilized electronic health record data from 3 integrated health care systems. Inverse probability of treatment weighting was used to adjust for covariates across 3 time periods, prepandemic (January 2019-March 2020), peak-pandemic shift to virtual care (April 2020-June 2020), and recovery of health care operations (July 2020-June 2021). First virtual follow-up behavioral health department encounters after an incident diagnostic encounter were examined for differences across the time periods in rates of antidepressant medication orders and fulfillments, and completion of patient-reported symptoms screeners in service of measurement-based care. RESULTS: Antidepressant medication orders declined modestly but significantly in 2 of the 3 systems during the peak-pandemic period but rebounded during the recovery period. There were no significant changes in patient fulfillment of ordered antidepressant medications. Completion of symptom screeners increased significantly in all 3 systems during the peak-pandemic period and continued to increase significantly in the subsequent period. CONCLUSIONS: A rapid shift to virtual behavioral health care was possible without compromising health-care-related practices. The transition and subsequent adjustment period have instead been marked by improved adherence to measurement-based care practices in virtual visits, signaling a potential new capacity for virtual health care delivery.

RESUMO

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.

RESUMO

BACKGROUND: Risk of type 2 diabetes mellitus (T2DM) in transgender and gender diverse (TGD) persons, especially those receiving gender-affirming hormone therapy (GAHT) is an area of clinical and research importance. METHODS: We used data from an electronic health record-based cohort study of persons 18 years and older enrolled in 3 integrated health care systems. The cohort included 2869 transfeminine members matched to 28 300 cisgender women and 28 258 cisgender men on age, race/ethnicity, calendar year, and site, and 2133 transmasculine members similarly matched to 20 997 cisgender women and 20 964 cisgender men. Cohort ascertainment spanned 9 years from 2006 through 2014 and follow-up extended through 2016. Data on T2DM incidence and prevalence were analyzed using Cox proportional hazards and logistic regression models, respectively. All analyses controlled for body mass index. RESULTS: Both prevalent and incident T2DM was more common in the transfeminine cohort relative to cisgender female referents with odds ratio and hazard ratio (95% CI) estimates of 1.3 (1.1-1.5) and 1.4 (1.1-1.8), respectively. No significant differences in prevalence or incidence of T2DM were observed across the remaining comparison groups, both overall and in TGD persons with evidence of GAHT receipt. CONCLUSION: Although transfeminine people may be at higher risk for T2DM compared with cisgender females, the corresponding difference relative to cisgender males is not discernable. Moreover, there is little evidence that T2DM occurrence in either transfeminine or transmasculine persons is attributable to GAHT use.

RESUMO

BACKGROUND: The effect of gender affirming hormone therapy (GAHT) on clinical laboratory parameters, including levels of liver enzymes alanine aminotransferase (ALT) and aspartate transaminase (AST), is an area of uncertainty in transgender health. AIM: We sought to estimate the distribution parameters of liver enzyme levels among transmasculine (TM) and transfeminine (TF) persons receiving GAHT relative to the corresponding measures in cisgender reference groups, and to evaluate longitudinal changes in these laboratory measures following GAHT initiation. METHODS: The data for this longitudinal study included 624 TF and 438 transmasculine (TM) people as well as 4,090 cisgender males and 4,797 cisgender females enrolled in 3 integrated health systems. Time under observation was divided into 2 intervals: from the first blood test to the date of the first filled GAHT prescription and from GAHT initiation to the most recent ALT or AST measurement. Linear mixed models were used to compare changes in log-transformed ALT and AST values among transgender cohort members before and after GAHT initiation, and relative to the reference groups. The results were expressed as relative differences (in %) and the ratios of these differences (ratios-of-ratios) along with the 95% confidence intervals (CIs). OUTCOMES: Changes in ALT and AST levels among transgender people over time and relative to the corresponding changes in cisgender referents. RESULTS: Among TM study participants, the post GAHT ratios-of-ratios for AST were 1.61 (95% CI: 1.13, 2.31) and 1.57 (95% CI: 1.06, 2.31) relative to cisgender males and females respectively. For ALT, the corresponding comparisons yielded the ratios-of-ratios (95% CIs) of 2.06 (1.67, 2.54) and 1.90 (1.50, 2.40). No statistically significant changes were observed among TF participants. Other factors associated with higher liver enzyme levels included alcohol use/abuse and obesity. CLINICAL IMPLICATIONS: TM persons may experience modest increases in ALT and AST concentrations following testosterone initiation; however, clinical significance of the observed association remains unclear and requires further investigation. By contrast, feminizing GAHT is unlikely to induce appreciable changes in liver enzyme levels. STRENGTH AND LIMITATIONS: The strengths of this study are the longitudinal design and the ability to assemble an unselected cohort nested within large health systems. The main limitations include the lack of information on hormone levels and the inability to take into account GAHT doses and routes of administration. CONCLUSION: The influence of long-term GAHT on ALT and AST levels appears modest and not likely to reflect clinically meaningful changes in liver function. Hashemi L, Zhang Q, Getahun D, et al.

RESUMO

OBJECTIVE: To examine temporal changes in the number and demographic composition of transgender/gender non-binary (TGNB) population using data from integrated health care systems. METHODS: Electronic health records from Kaiser Permanente health plans in Georgia and Northern and Southern California were used to identify TGNB individuals, who sought care from January 2006 to December 2014, and the data were analyzed by year, site, age, and sex assigned at birth. RESULTS: In 2006, the number of TGNB people (and corresponding 95% CI) per 100 000 population were 3.5 (1.9, 6.3) in Georgia, 5.5 (4.8, 6.4) in Southern California, and 17 (16, 19) in Northern California. In 2014, these frequencies increased to 38 (32, 45), 44 (42, 46), and 75 (72, 78) per 100 000 population, respectively. When analyzed by age, the most rapid increase was observed among persons 18 to 25 years old, and this increase accelerated after 2010. The ratio of transmasculine to transfeminine persons also changed from 1:1.7 in 2006 to 1:1 in 2014 overall and from 1:1 in 2006 to 1.8:1 in 2014 among persons <18 years of age. CONCLUSION: This analysis confirms previous observations that the proportion of TGNB people is growing, especially among young adults. The composition of the TGNB population is also changing from predominantly transfeminine to roughly 1:1 overall and to predominantly transmasculine in children and adolescents.

RESUMO

INTRODUCTION: In patients with haemophilia, general psychological distress as measured by the National Comprehensive Cancer Network (NCCN) distress thermometer has been associated with pain, disability and increased healthcare utilization. AIMS: To develop and validate a measure of haemophilia-related distress. METHODS: After qualitative interviews, the Hemophilia-Related Distress Questionnaire (HRDq) was developed. To validate the HRDq, adults (≥18 years) with haemophilia were enrolled, reported demographic and clinical information, and completed the HRDq and other questionnaires that measured similar constructs. Analysis included factor analysis and assessment of internal consistency using Cronbach's α, convergent validity using Pearson's correlation coefficient, and discriminant validity by comparing subgroups of patients. Test-retest reliability was assessed using an intraclass correlation coefficient (ICC). RESULTS: Among 130 enrolled participants, 126 (median age=32.7 years) completed the 24 item HRDq in a median time of 5.4 minutes with overall HRDq scores ranging from 2 to 83 (median score=31.5; higher scores indicating higher distress). Assessment of convergent validity demonstrated a strong correlation (ρ>.60) of the HRDq total score with the NCCN Distress Thermometer, Haem-A-QoL total Score, and PROMIS-29 Profile social role domain and a mild to moderate correlation with all other questionnaire domains (.3-.59, p < .05). Distress was higher among those who had less education, were not employed, and were disabled and was not significantly different among those with severe compared with non-severe disease. Assessment of test-retest reliability demonstrated an ICC value of .84 (95% CI .71-.91) for the total score. CONCLUSIONS: The HRDq demonstrates good internal consistency, construct and discriminant validity, and retest reliability with a low responder burden.

RESUMO

BACKGROUND: Patients with cystic fibrosis (CF) are at risk for CF-related bone disease. Women with CF may use estrogen supplementation for reasons other than skeletal health. It is unknown whether estrogen therapy has a beneficial impact on skeletal health in women with CF. METHODS: In this retrospective cohort study of women with CF followed at a single CF center, the lumbar spine bone mineral density (BMD) of women with CF exposed to supplemental and not exposed to supplemental estrogen were compared. Spline function models included the main effect of estrogen exposure and the interaction between age and estrogen supplementation. RESULTS: Of the 145 subjects analyzed, 44 subjects were exposed to supplemental estrogen. The baseline characteristics of estrogen exposed and unexposed subjects were similar except for use of CF transmembrane conductance regulator modulators and anti-osteoporosis medications. Women exposed to estrogen reached peak BMD around 21 years of age, but women not exposed to estrogen reached peak BMD around 25 years of age. A significant interaction of age and estrogen supplementation indicated that the lumbar spine BMD trajectories differed by exposure group. CONCLUSIONS: Our study demonstrates that few women with CF of reproductive age are prescribed estrogen therapy. Furthermore, estrogen exposure up to age 21 is associated with improved BMD, but estrogen exposure after age 21 does not appear to be associated with improved BMD. Further studies are needed to understand the reasons for the low rates of estrogen use in young women with CF and the optimal timing, dose and formulation of estrogen prescription.

RESUMO

BACKGROUND: Propofol is a preferred agent for many pediatric sedation providers because of its rapid onset and short duration of action. It allows for quick turn around times and enhanced throughput. Occasionally, intravenous (IV) methohexital (MHX), an ultra-short acting barbiturate is utilized instead of propofol. OBJECTIVE: Describe the experience with MHX in a primarily propofol driven outpatient sedation program and to see if it serves as an acceptable alternative when propofol is not the preferred pharmacologic option. METHODS: Retrospective chart review from 2012 to 2015 of patients receiving IV MHX as their primary sedation agent. Data collected included demographics, reason for methohexital use, dosing, type of procedure, success rate, adverse events (AE), duration of the procedure, and time to discharge. RESULTS: Methohexital was used in 240 patient encounters. Median age was 4years (IQR 2-7), 71.8% were male, and 80.4% were ASA-PS I or II. Indications for MHX use: egg+soy/peanut allergy in 93 (38.8%) and mitochondrial disorder 9 (3.8%). Median induction bolus was 2.1mg/kg (IQR, 1.9-2.8), median maintenance infusion was 4.5mg/kg/h (IQR, 3.0-6.0). Hiccups 15 (6.3%), secretions requiring intervention 14 (5.8%), and cough 12 (5.0%) were the most commonly occurring minor AEs. Airway obstruction was seen in 28 (11.6%). Overall success rate was 94%. Median time to discharge after procedure completion was 40.5min (IQR 28-57). CONCLUSION: Methohexital can be used with a high success rate and AEs that are not inconsistent with propofol administration. Methohexital should be considered when propofol is not a preferred option.

RESUMO

BACKGROUND: Iron deficiency and anemia affect up to 50% to 75% of patients with inflammatory bowel disease (IBD). Iron deficiency in IBD may be difficult to diagnose because of the effect of inflammation on iron status biomarkers. Thus, there is a need for better methods to accurately determine iron status in IBD. OBJECTIVE: The aim of the study was to investigate the association of inflammation with hemoglobin content of reticulocytes (CHr) and the utility of CHr in comparison to standard iron biomarkers. METHODS: We conducted a cross-sectional study of children with IBD. Iron biomarkers (CHr, ferritin, soluble transferrin receptor [sTfR], hepcidin, hemoglobin) were measured along with systemic biomarkers of inflammation (C-reactive protein, α1-acid glycoprotein]. Spearman correlations were used to evaluate the relation of inflammation and iron biomarkers. The criterion standard for iron deficiency was defined as inflammation-corrected ferritin <15 µg/L or sTfR >8.3 mg/L. Receiver operating characteristic curves were used to estimate the prognostic values of all iron biomarkers to identify patients with iron deficiency. RESULTS: We analyzed data in 62 children ages 5 to 18 years. Sixty-nine percent of our subjects had Crohn disease and 31% had ulcerative colitis, of which 42% were girls and 53% African American. The prevalence of anemia was 32%, of iron deficiency was 52% using ferritin <15 µg/L or sTfR >8.3 mg/L, 39% using red blood cell distribution width of >14.5%, 26% using body iron stores of <0 mg/kg body weight, 25% using CHr of <28 pg, and 11% using mean corpuscular volume of <75 fL/cell. The prevalence of elevated CRP or AGP was 48%. After correcting ferritin and sTfR levels for inflammation, the prevalence of iron deficiency was 68%. CHr was correlated with C-reactive protein (rs -0.44, P < 0.001) and α1-acid glycoprotein (rs -0.37, P < 0.05). The optimal prognostic value for inflammation-adjusted CHr to predict iron deficiency was 34 pg (area under the receiver operating characteristic of 0.70), with 88% sensitivity and 30% specificity. CONCLUSIONS: Iron deficiency and anemia are common in this pediatric IBD cohort. All explored iron biomarkers, including CHr, were affected by inflammation and should be adjusted. A single iron biomarker is unlikely to best predict iron deficiency in pediatric IBD. Iron intervention studies are needed to examine the response of iron biomarkers to iron supplementation in the setting of inflammation.

RESUMO

We report results of a pilot study of high-dose vitamin D in sickle cell disease (SCD). Subjects were given a 6-week course of oral high-dose cholecalciferol (4000-100 000 IU per week) or placebo and monitored prospectively for a period of six months. Vitamin D insufficiency and deficiency was present at baseline in 82·5% and 52·5% of subjects, respectively. Subjects who received high-dose vitamin D achieved higher serum 25-hydroxyvitamin D, experienced fewer pain days per week, and had higher physical activity quality-of-life scores. These findings suggest a potential benefit of vitamin D in reducing the number of pain days in SCD. Larger prospective studies with longer duration are needed to confirm these effects.
