Does vaginal estrogen use increase the risk for adverse cardiovascular outcomes?

NO. In general, nonoral estrogen use for menopausal symptoms is associated with a lower cardiovascular (CV) risk profile than oral estrogen use (strength of recommendation [SOR], B; meta-analysis of cohort studies). Vaginal estrogen use is associated with lower risk for coronary heart disease (CHD) and similar risk for myocardial infarction (MI), stroke, and deep vein thrombosis/pulmonary embolism (DVT/ PE) compared with nonuse (SOR, B; cohort studies). Vaginal estrogen therapy also is associated with lower CV-related mortality for 3 to 5 years compared withnonuse (SOR, B; cohort study). No high-quality randomized trials address this topic.

Does an early COPD diagnosis improve long-term outcomes?

It depends. A diagnosis of chronic obstructive pulmonary disease (COPD) made using screening spirometry in patients without symptoms does not change the course of the disease or alter smoking rates (strength of recommendation [SOR]: A, preponderance of evidence from multiple randomized controlled trials [RCTs]). However, once a patient develops symptoms of lung disease, a delayed diagnosis is associated with poorer outcomes (SOR: B, cohort studies). Active case finding (including the use of spirometry) is recommended for patients with risk factors for COPD who present with consistent symptoms (SOR: C, expert opinion).

Can family physicians accurately screen for AAA with point-of-care ultrasound?

Likely yes. Point-of-care ultrasound (POCUS) screening for abdominal aortic aneurysm (AAA) by nonradiologist physicians is 98% sensitive and 99% specific, compared with imaging performed by radiologists (strength of recommendation [SOR]: B, meta-analysis of diagnostic accuracy studies mostly involving emergency medicine physicians). European family physicians demonstrated 100% concordance with radiologist readings (SOR: C, very small subsequent diagnostic accuracy studies).

Room for Improvement: Rates of Birth Cohort Hepatitis C Screening in Primary Care Practices-A WWAMI Region Practice and Research Network Study.

Introduction: An estimated 2.4 million people in the United States live with hepatitis C. Though there are effective treatments for chronic hepatitis C, many infected individuals remain untreated because 40% to 50% of individuals with chronic hepatitis C are unaware of their hepatitis C status. In 2013, the United States Preventive Services Task Force (USPSTF) recommended that adults born between 1945 and 1965 should be offered one-time hepatitis C screening. The purpose of this study is to describe rates of birth cohort hepatitis C screening across primary care practices in the WWAMI region Practice and Research Network (WPRN). Methods: Cross-sectional observational study of adult patients born between 1945 and 1965 who also had a primary care visit at 1 of 9 participating health systems (22 primary care clinics) between July 31, 2013 and September 30, 2015. Data extracted from the electronic health record systems at each clinic were used to calculate the proportion of birth cohort eligible patients with evidence of hepatitis C screening as well as proportions of screened patients with positive hepatitis C screening test results. Results: Of the 32 139 eligible patients, only 10.9% had evidence of hepatitis C screening in the electronic health record data (range 1.2%-49.1% across organizations). Among the 4 WPRN sites that were able to report data by race and ethnicity, the rate of hepatitis C screening was higher among African Americans (39.9%) and American Indians/Alaska Natives (23.2%) compared with Caucasians (10.7%; P < .001). Discussion: Rates of birth cohort hepatitis C screening are low in primary care practices. Future research to develop and test interventions to increase rates of birth cohort hepatitis C screening in primary care settings are needed.

Patient Willingness to Have Tests to Guide Antibiotic Use for Respiratory Tract Infections: From the WWAMI Region Practice and Research Network (WPRN).

INTRODUCTION: The majority of consultations for acute respiratory tract infections (RTIs) lead to prescriptions for antibiotics, which have limited clinical benefit. We explored patients' willingness to have blood tests as part of the diagnostic work-up for RTIs, and patient knowledge about antibiotics. METHODS: Patients at 6 family medicine clinics were surveyed. Regression modeling was used to determine independent predictors of willingness to have venous and point-of-care (POC) blood tests, and knowledge of the value of antibiotics for RTIs. RESULTS: Data were collected from 737 respondents (response rate 83.8%), of whom 65.7% were women, 60.1% were white, and 25.1% were current smokers; patients' mean age was 46.9 years. Sex (female), race (white), and a preference to avoid antibiotics were independent predictors of greater level of antibiotic knowledge. A total of 63.1% were willing to have a venous draw and 79% a POC blood test, to help guide antibiotic decision-making. Non-American Indian/Alaskan Native race, current smoking, and greater knowledge of antibiotics were independent predictors of willingness to have a POC test. CONCLUSION: A large majority of patients seemed willing to have POC tests to facilitate antibiotic prescribing decisions for RTIs. Poor knowledge about antibiotics suggests better education regarding antibiotic use might influence patient attitudes towards use of antibiotics for RTIs.

Clinical Inquiry: What therapies alleviate symptoms of polycystic ovary syndrome?

Women with PCOS who are not seeking pregnancy commonly have symptoms such as excessive weight, hirsutism, and menstrual irregularities. This review focuses on interventions to manage those symptoms.

Clinical Inquiry: Do venlafaxine and gabapentin control hot flashes in women with a history of breast cancer?

Venlafaxine reduces hot flashes more than placebo in women with a history of breast cancer; adverse effects include dry mouth and constipation.
