Position Paper: SGIM Sex- and Gender-Based Women's Health Core Competencies.

Women's health care has evolved significantly since it was first acknowledged as an integral part of internal medicine training more than two decades ago. To update and clarify core competencies in sex- and gender-based women's health for general internists, the Society of General Internal Medicine (SGIM) Women and Medicine Commission prepared the following Position Paper, approved by the SGIM council in 2023. Competencies were developed using several sources, including the 2021 Accreditation Council for Graduate Medical Education Program Requirements for Internal Medicine and the 2023 American Board of Internal Medicine Certification Examination Blueprint. These competencies are relevant to the care of patients who identify as women, as well as gender-diverse individuals to whom these principles apply. They align with pivotal advances in women's health and acknowledge the changing context of patients' lives, reaffirming the role of general internal medicine physicians in providing comprehensive care to women.

Effect of 5 weeks of oral acetazolamide on patients with pulmonary vascular disease: A randomized, double-blind, cross-over trial.

BACKGROUND: The carbonic anhydrase inhibitor acetazolamide stimulates ventilation through metabolic acidosis mediated by renal bicarbonate excretion. In animal models, acetazolamide attenuates acute hypoxia-induced pulmonary hypertension (PH), but its efficacy in treating patients with PH due to pulmonary vascular disease (PVD) is unknown. METHODS: 28 PVD patients (15 pulmonary arterial hypertension, 13 distal chronic thromboembolic PH), 13 women, mean±SD age 61.6±15.0 years stable on PVD medications, were randomised in a double-blind crossover protocol to 5 weeks acetazolamide (250mg b.i.d) or placebo separated by a ≥2 week washout period. Primary endpoint was the change in 6-minute walk distance (6MWD) at 5 weeks. Additional endpoints included safety, tolerability, WHO functional class, quality of life, arterial blood gases, and hemodynamics (by echocardiography). RESULTS: Acetazolamide had no effect on 6MWD compared to placebo (treatment effect: mean change [95%CI] -18 [-40 to 4]m, p=0.102) but increased arterial blood oxygenation through hyperventilation induced by metabolic acidosis. Other measures including pulmonary hemodynamics were unchanged. No severe adverse effects occurred, side effects that occurred significantly more frequently with acetazolamide vs. placebo were change in taste (22/0%), paraesthesia (37/4%) and mild dyspnea (26/4%). CONCLUSIONS: In patients with PVD, acetazolamide did not change 6MWD compared to placebo despite improved blood oxygenation. Some patients reported a tolerable increase in dyspnoea during acetazolamide treatment, related to hyperventilation, induced by the mild drug-induced metabolic acidosis. Our findings do not support the use of acetazolamide to improve exercise in patients with PVD at this dosing. GOV IDENTIFIER: NCT02755298.

Sleep Position Detection for Closed-Loop Treatment of Sleep-Related Breathing Disorders.

Reliable detection of sleep positions is essential for the development of technical aids for patients with position-dependent sleep-related breathing disorders. We compare personalized and generalizable sleeping position classifiers using unobtrusive eight-channel pressure-sensing mats. Data of six male patients with confirmed position-dependent sleep apnea was recorded during three subsequent nights. Personalized position classifiers trained using leave-one-night-out cross-validation on average reached an F1-score of 61.3% for supine/non-supine and an F1-score of 46.2% for supine/lateral-left/lateral-right classification. The generalizable classifiers reached average F1-scores of 62.1% and 49.1% for supine/non-supine and supine/lateral-left/lateral-right classification, respectively. In-bed presence ("bed occupancy") could be detected with an average F1-score of 98.1%. This work shows that personalized sleep-position classifiers trained with data from two nights have comparable performance to classifiers trained with large interpatient datasets. Simple eight-channel sensor mattresses can be used to accurately detect in-bed presence required for closed-loop systems but their use to classify sleep-positions is limited.

Future Pregnancy Considerations after Premature Birth of an Infant Requiring Intensive Care: A Qualitative Study.

BACKGROUND: Postpartum contraception counseling and method use vary widely among patients who had a preterm birth. We performed this study to explore what issues and concerns individuals with preterm infants requiring intensive care describe as influencing their postpartum contraceptive choices. METHODS: We conducted a qualitative study using semi-structured interviews with participants who gave birth to a singleton preterm infant admitted to the neonatal intensive care unit (NICU). We explored pregnancy, childbirth, postpartum care, and NICU experiences, as well as future reproductive plans and postpartum contraceptive choices. Two coders used a constant-comparative approach to code transcripts and identify themes. RESULTS: We interviewed 26 participants: 4 (15%) gave birth at less than 26, 6 (23%) at 26 to 27 6/7, 8 (31%) at 28 to 31 6/7, and 8 (31%) at 32 to 36 6/7 weeks of gestation. We identified three main themes related to future pregnancy plans and contraception choice. First, participants frequently described their preterm birth and their infants' NICU hospitalization as traumatic experiences that affected plans for future pregnancies. The loss of control in predicting or preventing a future preterm birth and uncertainty about their premature child's future medical needs resulted in participants wanting to avoid going through the same experience with another child. Second, participants chose contraception based on previous personal experiences, desired method features, and advice from others. Last, having a preterm birth did not result in any ambivalence among those who desired permanent contraception. CONCLUSIONS: Preterm birth influences future pregnancy plans. When discussing reproductive goals with patients, clinicians should be aware of potential trauma associated with a premature birth, assess for whether patients want to discuss contraception, and center the conversation around individual needs if patients do desire contraceptive counseling.

Bone infection: a clinical priority for clinicians, scientists and educators.

Bone infection has received increasing attention in recent years as one of the main outstanding clinical problems in orthopaedic-trauma surgery that has not been successfully addressed. In fact, infection may develop across a spectrum of patient types regardless of the level of perioperative management, including antibiotic prophylaxis. Some of the main unknown factors that may be involved, and the main targets for future intervention, include more accurate and less invasive diagnostic options, more thorough and accurate debridement protocols, and more potent and targeted antimicrobials. The underlying biology dominates the clinical management of bone infections, with features such as biofilm formation, osteolysis and vascularisation being particularly influential. Based on the persistence of this problem, an improved understanding of the basic biology is deemed necessary to enable innovation in the field. Furthermore, from the clinical side, better evidence, documentation and outreach will be required to translate these innovations to the patient. This review presents the findings and progress of the AO Trauma Clinical Priority Program on the topic of bone infection.

IgG4-specific responses in patients with Staphylococcus aureus bone infections are not predictive of postoperative complications.

The most prevalent pathogen in bone infections is Staphylococcus aureus; its incidence and severity are partially determined by host factors. Prior studies showed that anti-glucosaminidase (Gmd) antibodies are protective in animals, and 93.3 % of patients with culture-confirmed S. aureus osteomyelitis do not have anti-Gmd levels > 10 ng/mL in serum. Infection in patients with high anti-Gmd remains unexplained. Are anti-Gmd antibodies in osteomyelitis patients of the non-opsonising, non-complement-fixing IgG4 isotype? The relative amounts of IgG4 and total IgG against Gmd and 7 other S. aureus antigens: iron-surface determinants (Isd) IsdA, IsdB, and IsdH, amidase (Amd), α-haemolysin (Hla), chemotaxis inhibitory protein from S. aureus (CHIPS), and staphylococcal-complement inhibitor (SCIN) were determined in sera from healthy controls (Ctrl, n = 92), osteomyelitis patients whose surgical treatment resulted in infection control (IC, n = 95) or an adverse outcome (AD, n = 40), and post-mortem (PM, n = 7) blood samples from S. aureus septic-death patients. Anti-Gmd IgG4 levels were generally lower in infected patients compared to controls; however, levels among the infected were higher in AD than IC patients. Anti-IsdA, IsdB and IsdH IgG4 levels were increased in infected patients versus controls, and Jonckheere-Terpstra tests of levels revealed an increasing order of infection (Ctrl < IC < AD < PM) for anti-Isd IgG4 antibodies and a decreasing order of infection (Ctrl > IC > AD > PM) for anti-autolysin (Atl) IgG4 antibodies. Collectively, this does not support an immunosuppressive role of IgG4 in S. aureus osteomyelitis but is consistent with a paradigm of high anti-Isd and low anti-Atl responses in these patients.

Effectiveness and cost effectiveness of a stress management training for leaders of small and medium sized enterprises - study protocol for a randomized controlled-trial.

BACKGROUND: Leaders in small and medium-sized enterprises (SMEs) are exposed to increased stress as a result of a range of challenges. Moreover, they rarely have the opportunity to participate in stress management trainings. Therefore, KMU-GO (ger: Kleine und mittlere Unternehmen - Gesundheitsoffensive; en: small and medium-sized enterprises - health campaign) aims at conducting and evaluating such a stress management training. The focus of evaluation does not only lie on the effects on leaders participating but also on their employees. METHODS: The study is planned as a 2 × 3 mixed design with two groups (intervention and waiting control group) as a between factor and point in time (at baseline, 6 and 12 months later) as a within factor. We aim at collecting data from N = 200 leaders. Based on the results of a preceding assessment, an already successfully implemented stress management training was adapted to SME needs and now serves as the framework of this intervention. The stress management training comprises one and a half days and is followed by two booster sessions (each 180 min) about 3 and 6 months after the training. The main focus of this intervention lies on specifying leaders stress reactivity while at the same time investigating its effects on employees' mental health. Further dependent variables are leaders´ depression and anxiety scores, effort-reward imbalance, sick days and psychophysiological measures of heart rate variability, hair cortisol, and salivary alpha-amylase. Cost-effectiveness analyses will be conducted from a societal and employers' point of view. DISCUSSION: Stress management is a highly relevant issue for leaders in SMEs. By providing an adequate occupational stress management training, we expect to improve leaders´ and also employees` mental health, thereby preventing economic losses for SMEs and the national economy. However, collecting data from employees about the success of a stress management training of their leader is a highly sensitive topic. It requires a carefully planned proceeding ensuring for example a high degree of transparency, anonymity, and providing team incentives. TRIAL REGISTRATION: The KMU-GO trial is registered at the German Clinical Trial Register (DRKS): DRKS00023457 (05.11.2020).

Development and Pilot Testing of a Patient-Centered Web-Based Reproductive Decision Support Tool for Primary Care.

BACKGROUND: Patient-centered counseling to help women achieve their reproductive goals is an essential yet often absent component of primary care. OBJECTIVE: We developed and piloted MyPath, a novel web-based decision support tool integrating reproductive goals assessment, information about optimizing health before pregnancy, and contraceptive decision support, for use prior to primary care visits in the Veterans Administration (VA). DESIGN: We created MyPath using best practices for decision tool development, including a conceptual framework informed by theory and user-centered design with input from patients, providers, and scientific experts. We conducted a non-randomized pilot in two VA Women's Health primary care clinics. A control group (n = 28) was recruited prior to and intervention group (n = 30) recruited after introduction of MyPath into clinics. PARTICIPANTS: Women Veterans ages 18-44 with an upcoming visit scheduled with one of eight providers. INTERVENTIONS: After recruitment of controls, providers and staff received a brief introduction to MyPath. Patients scheduled to see providers in the intervention phase used MyPath on an iPad in the waiting room prior to their visit. MAIN MEASURES: Acceptability, feasibility, discussions about pregnancy and/or contraceptive needs, and contraceptive decision quality by a survey of participants and providers. KEY RESULTS: Nearly all participants who used MyPath reported they learned new information (97%) and would recommend it to other Veterans (93%). No providers reported that MyPath significantly increased workload. A greater proportion of intervention participants reported having discussions about reproductive needs in their visit compared to controls (93% vs 68%; p = 0.02). Intervention participants also experienced greater increases in pre-/post-visit knowledge and communication self-efficacy and a trend towards greater reduction in contraceptive decision conflict compared to controls. CONCLUSIONS: MyPath was highly acceptable to women, increased the proportion of primary care visits addressing reproductive needs, and improved decision quality without increasing providers' perceived workload. A larger randomized evaluation of effectiveness is warranted.

Deriving a dose and regimen for anti-glucosaminidase antibody passive-immunisation for patients with Staphylococcus aureus osteomyelitis.

Staphylococcus aureus (S. aureus) osteomyelitis remains a major clinical problem. Anti-glucosaminidase (Gmd) antibodies (1C11) are efficacious in prophylactic and therapeutic murine models. Feasibility, safety and pharmacokinetics of 1C11 passive immunisation in sheep and endogenous anti-Gmd levels were quantified in osteomyelitis patients. 3 sheep received a 500 mg intravenous (i.v.) bolus of 1C11 and its levels in sera were determined by enzyme-linked immunosorbent assay (ELISA) over 52 d. A humanised anti-Gmd monoclonal antibody, made by grafting the antigen-binding fragment (Fab) portion of 1C11 onto the fragment crystallisable region (Fc) of human IgG1, was used to make a standard curve of mean fluorescent intensity versus concentration of anti-Gmd. Anti-Gmd serum levels were determined in 297 patients with culture-confirmed S. aureus osteomyelitis and 40 healthy controls. No complications or adverse events were associated with the sheep 1C11 i.v. infusion and the estimated circulating half-life of 1C11 was 23.7 d. Endogenous anti-Gmd antibody levels in sera of osteomyelitis patients ranged from < 1 ng/mL to 300 µg/mL, with a mean concentration of 21.7 µg/mL. The estimated circulating half-life of endogenous anti-Gmd antibodies in sera of 12 patients with cured osteomyelitis was 120.4 d. A clinically relevant administration of anti-Gmd (500 mg i.v. = 7 mg/kg/70 kg human) was safe in sheep. This dose was 8 times more than the endogenous anti-Gmd levels observed in osteomyelitis patients and was predicted to have a half-life of > 3 weeks. Anti-Gmd passive immunisation has potential to prevent and treat S. aureus osteomyelitis. Further clinical development is warranted.

Copper intrauterine device placement 6-14 days after unprotected sex.

OBJECTIVE: To evaluate pregnancy risk following copper (CuT380A) intrauterine device (IUD) placement 6-14 days after unprotected intercourse. STUDY DESIGN: We used a combined dataset from four protocols in which participants had received a CuT380A IUD regardless of recent unprotected intercourse. At entry, participants had negative point of care urine pregnancy testing and reported all acts of unprotected intercourse in the two weeks prior to IUD placement. We identified a subset of women who had placement 6-14 days after unprotected intercourse and provided follow-up information on pregnancy status 2-4 weeks after IUD insertion. This follow-up within the four protocols included self -administered home urine pregnancy test (UPT) results 2-4 weeks after IUD placement or continued contact for up to 6 months. RESULTS: We identified 134 women who had a CuT380A IUD placed 6-14 days after unprotected intercourse and provided follow-up information on pregnancy status. Ninety-five (71%) participants reported UPT results 2-4 weeks after placement and the other 39 women were followed for 6 months after IUD placement to assess pregnancy status. Zero (97.5% CI 0-2.7%) participants reported a pregnancy within four weeks of CuT380A IUD placement. CONCLUSION: In these collected data, no women with recent unprotected intercourse became pregnant within 1 month of CuT380A IUD placement. IMPLICATION: These data indicate a low likelihood of pregnancy among women who reported unprotected intercourse 6-14 days preceding IUD insertion. For many women and their providers, these data may be sufficient to support same-day placement of a copper IUD rather than delaying IUD placement until the next menses.

A murine femoral ostectomy model with hardware exchange to assess antibiotic-impregnated spacers for implant-associated osteomyelitis.

Implant-associated osteomyelitis is a chronic infection that complicates orthopaedic surgeries. Once infected, 50 % of patients suffer treatment failure, resulting in high healthcare costs. While various small animal models have been developed to investigate the efficacy of prophylactic and therapeutic treatments, the minute scale of murine-model bone and hardware has been prohibitive for evaluating interventions with a complete implant exchange in the setting of an infected critical defect. To address this, the aim of the present study was to develop a murine femur model in which an initial mid-diaphyseal infection was established by surgical implantation of a titanium screw contaminated with bioluminescent Staphylococcus aureus (Xen36). 7 d after the infection was established, an ostectomy was performed to remove the middle segment (3 mm flanking the infected screw hole) and a bone-cement spacer, with or without impregnated gentamicin, was secured with a plate and screws to fix the septic segmental defect. Longitudinal bioluminescent imaging revealed a significant decrease in Xen36 growth following one-stage revision, with the antibiotic-impregnated spacer treated systemically with vancomycin (p < 0.05). This result was corroborated by a significant decrease in colony forming units (CFU) recovered from spacer, bone, soft tissue and hardware 12 d post-operative (p < 0.05). However, ~ 105 CFU/g Xen36 still persisted within the bone despite a clinical therapeutic regimen. Therefore, the model enables the investigation of new therapeutic strategies to improve upon the current standard of care in a mouse model of implant-associated osteomyelitis that employs reconstruction of a critical defect.

Intra-individual variability of long-chain fatty acids (C12-C24) in plasma and red blood cells.

Long-chain fatty acids (LCFA) play key roles in mammalian cells as sources of energy, structural components and signaling molecules. Given their importance in numerous physiological processes, the roles of LCFAs in health and disease have been extensively investigated. In the majority of studies, correlations are established using a single measurement in plasma or red blood cells (RBCs). Although a few studies have reported on reproducibility of individual fatty acid measurements, the comprehensive analysis of intra-individual LCFA variability has not been performed. Therefore, our goal was to determine intra-individual variability for the 22 most abundant LCFAs in both plasma and RBC samples collected from healthy individuals on a regular diet after overnight fasting. The measurements of LCFAs in RBCs were consistent throughout the course of study reflecting long-term nutritional status. In contrast, the results in plasma showed considerable LCFA intra-individual variability, even between fatty acids of the same type. Plasma intra-individual variability for omega-3 alpha-linolenic and eicosapentaenoic acids in some participants were >40% whereas the variability of docosahexaenoic acid was consistently <12.8%. Omega-6 linoleic and arachidonic acids also showed low variability in plasma. The results suggest that some LCFAs have less variability and would be more reliable as biomarkers. Reliability of biomarkers can have a profound impact on the research outcomes. Intra-individual variability of LCFAs should be taken into consideration in designing, conducting and interpreting results of clinical studies.

[Pulmonary hypertension in connective tissue disease]. / Pulmonale Hypertonie bei Kollagenosen.

Pulmonary arterial hypertension (PAH) is a major complication of systemic sclerosis (SSc) and screening is recommended for a timely initiation of disease-targeted drug therapy to modify disease progression. Patients with SSc-PAH have a better prognosis when detected and treated early. The PAH can occur in all disease stages and subsets of SSc. Regular screening tests, which are indicative for PAH, e.g. echocardiography, diffusion capacity, brain natriuretic protein (BNP) and a 6-min walking test, are recommended to enhance the suspicion, since clinical symptoms are unspecific and occur late in the course of PAH. In patients with suspected PAH, the diagnosis should be confirmed by right heart catheterization. A multidisciplinary approach in expert centres including rheumatologists and respiratory physicians and cardiologists specialized in pulmonary hypertension is mandatory for management of patients with SSc at risk for or with manifest pulmonary arterial hypertension.

Load transfer and periprosthetic fractures after total hip arthoplasty: Comparison of periprosthetic fractures of femora implanted with cementless distal-load or proximal-load femoral components and measurement of the femoral strain at the time of implantation.

BACKGROUND: Little is known about the causes and mechanisms underlying periprosthetic fractures around femoral components particularly in relation to the stem design. In an in vitro study 20 pairs of fresh cadaveric femora were loaded to fracture axially and transversally. FINDINGS: When proximal femoral strain was measured at the time of impaction of cementless stems the load transfer was determined by the underlying anatomy rather than by the shape of the stem, so that the so-called "load transfer" properties - proximal or distal - ascribed to stem designs are a myth. The axial-load and the transverse-load model were then exposed to loads to failure (fracture) and showed a biphasic pattern throughout independent of the impact direction. In the second phase, the fracture phase proper, the bone behaved like a brittle solid. Failure occurred very rapidly within less than 5 milliseconds. The forces to failure were between 2 and 11 kN. Most of the fractures (82.5%) occurred above the stem tip. INTERPRETATION: Note that the study was confined to early preosteointegration fractures. Neither the stem design nor the impact direction, i.e. on the knee or on the side of the hip, was related to the fracture morphology.

Cerebellar volume and cerebellocerebral structural covariance in schizophrenia: a multisite mega-analysis of 983 patients and 1349 healthy controls.

Although cerebellar involvement across a wide range of cognitive and neuropsychiatric phenotypes is increasingly being recognized, previous large-scale studies in schizophrenia (SZ) have primarily focused on supratentorial structures. Hence, the across-sample reproducibility, regional distribution, associations with cerebrocortical morphology and effect sizes of cerebellar relative to cerebral morphological differences in SZ are unknown. We addressed these questions in 983 patients with SZ spectrum disorders and 1349 healthy controls (HCs) from 14 international samples, using state-of-the-art image analysis pipelines optimized for both the cerebellum and the cerebrum. Results showed that total cerebellar grey matter volume was robustly reduced in SZ relative to HCs (Cohens's d=-0.35), with the strongest effects in cerebellar regions showing functional connectivity with frontoparietal cortices (d=-0.40). Effect sizes for cerebellar volumes were similar to the most consistently reported cerebral structural changes in SZ (e.g., hippocampus volume and frontotemporal cortical thickness), and were highly consistent across samples. Within groups, we further observed positive correlations between cerebellar volume and cerebral cortical thickness in frontotemporal regions (i.e., overlapping with areas that also showed reductions in SZ). This cerebellocerebral structural covariance was strongest in SZ, suggesting common underlying disease processes jointly affecting the cerebellum and the cerebrum. Finally, cerebellar volume reduction in SZ was highly consistent across the included age span (16-66 years) and present already in the youngest patients, a finding that is more consistent with neurodevelopmental than neurodegenerative etiology. Taken together, these novel findings establish the cerebellum as a key node in the distributed brain networks underlying SZ.

[The Aut-idem Rule and the Importance of Patient-Individual Selection of Inhalers for the Therapy of Airway Diseases in Practices of Pneumologists and General Practitioners - Assessment and Implementation by Pneumologists and General Practitioners]. / Aut-idem-Regelung und Inhalatorauswahl bei inhalativer Therapie in pneumologischen und hausärztlichen Praxen unter Alltagsbedingungen ­ Einschätzung und Umsetzung durch Pneumologen und Hausärzte.

Drug therapy of obstructive airway diseases mainly relies on inhaled medication. The success of this therapy depends primarily on the selection of the appropriate inhaler considering patient's choice and the correct application. The aut-idem-rule, an active exclusion of the optional substitution by the pharmacist, allows prescribing physicians to ensure the delivery of a particular inhaler, which was selected for that patient, who was trained to use specifically that inhaler. This survey shows that pneumologists and, to a greater extent general practitioners, do not consistently make use of this option, although they unanimously agree on the importance of targeted inhaler selection. As a result, patients may receive different inhalers in the pharmacy, where the inhaler is chosen under consideration of market-driven aspects such as rebate contracts or stock. This causes that patients get confused by the exchange of their inhaler. Thus the exchange of the inhaler by the pharmacist leads to uncertainty and application problems in patients. Hence, the success of the comparatively complex inhaled therapy is endangered. This could be prevented, if prescribing physicians were informed and supported consistently regarding the use of aut-idem exclusion to ensure an optimal therapy for each individual patient.

A large animal model for a failed two-stage revision of intramedullary nail-related infection by methicillin-resistant Staphylococcus aureus.

The treatment of chronic orthopaedic device-associated infection (ODRI) often requires multiple surgeries and prolonged antibiotic therapy. Despite this extensive treatment protocol, the procedure is associated with significant failure rates. Currently, no large animal model is available that recapitulates a failed revision. Therefore, our aim was to establish a large animal model for failed treatment of an ODRI in order to serve as a testbed for future interventional strategies. Adult Swiss Alpine sheep received an intramedullary nail in the tibia and a localised inoculum of either a methicillin-sensitive or methicillin-resistant Staphylococcus aureus (MSSA, MRSA respectively). After 8 weeks, when chronic infection had been established, the animals underwent a staged revision with debridement and temporary placement of an antibiotic-loaded cement spacer. Antibiotics were delivered systemically in a standard or pathogen-adapted manner. Debridement and implant exchange alone failed to treat the MSSA infection. Neither local therapy alone nor systemic therapy alone were effective in resolving infection with MSSA, but a combination of local and systemic therapy was effective against it. MRSA infection was not resolved by the combination of local and systemic antibiotics (standard or pathogen-adapted). A model for failed revision of MRSA infection is described despite the use of local and systemic antibiotics. Novel interventions may be assessed using this model, including antibiotic and non-antibiotic interventions.

Unintended Pregnancy and Contraceptive Use Among Women Veterans: The ECUUN Study.

BACKGROUND: Little is known about contraceptive care for the growing population of women veterans who receive care in the Veterans Administration (VA) healthcare system. OBJECTIVE: To determine rates of contraceptive use, unmet need for prescription contraception, and unintended pregnancy among reproductive-aged women veterans. DESIGN AND PARTICIPANTS: We conducted a cross-sectional, telephone-based survey with a national sample of 2302 women veterans aged 18-44 years who had received primary care in the VA within the prior 12 months. MAIN MEASURES: Descriptive statistics were used to estimate rates of contraceptive use and unintended pregnancy in the total sample. We also estimated the unmet need for prescription contraception in the subset of women at risk for unintended pregnancy. For comparison, we calculated age-adjusted US population estimates using data from the 2011-2013 National Survey of Family Growth (NSFG). KEY RESULTS: Overall, 62% of women veterans reported current use of contraception, compared to 68% of women in the age-adjusted US population. Among the subset of women at risk for unintended pregnancy, 27% of women veterans were not using prescription contraception, compared to 30% in the US population. Among women veterans, the annual unintended pregnancy rate was 26 per 1000 women; 37% of pregnancies were unintended. In the age-adjusted US population, the annual rate of unintended pregnancy was 34 per 1000 women; 35% of pregnancies were unintended. CONCLUSIONS: While rates of contraceptive use, unmet contraceptive need, and unintended pregnancy among women veterans served by the VA are similar to those in the US population, these rates are suboptimal in both populations, with over a quarter of women who are at risk for unintended pregnancy not using prescription contraception, and unintended pregnancies accounting for over a third of all pregnancies. Efforts to improve contraceptive service delivery and to reduce unintended pregnancy are needed for both veteran and civilian populations.

Racial and ethnic disparities in contraceptive knowledge among women veterans in the ECUUN study.

OBJECTIVE: To assess whether racial/ethnic disparities in contraceptive knowledge observed in the general US population are also seen among women Veterans served by the Veterans Affairs (VA) healthcare system. STUDY DESIGN: We analyzed data from a national telephone survey of 2302 women Veterans aged 18-44 who had received care within VA in the prior 12 months. Twenty survey items assessed women's knowledge about various contraceptive methods. Multivariable logistic regression was used to examine racial/ethnic variation in contraceptive knowledge items, adjusting for age, marital status, education, income, parity, and branch of military service. RESULTS: Contraceptive knowledge was low among all participants, but black and Hispanic women had lower knowledge scores than whites in almost all knowledge domains. Compared to white women, black women were significantly less likely to answer correctly 15 of the 20 knowledge items, with the greatest adjusted difference observed in the item assessing knowledge about the reversibility of tubal sterilization (adjusted percentage point difference (PPD): -23.0; 95% CI: -27.8, -18.3). Compared to white women, Hispanic women were significantly less likely to answer correctly 11 of the 20 knowledge items, with the greatest adjusted difference also in the item assessing tubal sterilization reversibility (PPD: -13.1; 95% CI: -19.5, -6.6). CONCLUSION: Contraceptive knowledge among women Veterans served by VA is suboptimal, especially among racial/ethnic minority women. Improving women's knowledge about important aspects of available contraceptive methods may help women better select and effectively use contraception. IMPLICATIONS: Providers in the VA healthcare system should assess and address contraceptive knowledge gaps as part of high-quality, patient-centered reproductive health care.
