ImportanceCarotid artery stenosis is atherosclerotic disease that affects extracranial carotid arteries. Asymptomatic carotid artery stenosis refers to stenosis in persons without a history of ischemic stroke, transient ischemic attack, or other neurologic symptoms referable to the carotid arteries. The prevalence of asymptomatic carotid artery stenosis is low in the general population but increases with age.ObjectiveTo determine if its 2014 recommendation should be reaffirmed, the US Preventive Services Task Force (USPSTF) commissioned a reaffirmation evidence review. The reaffirmation update focused on the targeted key questions on the potential benefits and harms of screening and interventions, including revascularization procedures designed to improve carotid artery blood flow, in persons with asymptomatic carotid artery stenosis.PopulationThis recommendation statement applies to adults without a history of transient ischemic attack, stroke, or other neurologic signs or symptoms referable to the carotid arteries.Evidence assessmentThe USPSTF found no new substantial evidence that could change its recommendation and therefore concludes with moderate certainty that the harms of screening for asymptomatic carotid artery stenosis outweigh the benefits.RecommendationThe USPSTF recommends against screening for asymptomatic carotid artery stenosis in the general adult population. (D recommendation).

ImportanceTobacco use is the leading preventable cause of disease, disability, and death in the US. In 2014, it was estimated that 480 000 deaths annually are attributed to cigarette smoking, including second hand smoke exposure. Smoking during pregnancy can increase the risk of numerous adverse pregnancy outcomes (eg, miscarriage and congenital anomalies) and complications in the offspring (including sudden infant death syndrome and impaired lung function in childhood). In 2019, an estimated 50.6 million US adults (20.8% of the adult population) used tobacco; 14.0% of the US adult population currently smoked cigarettes and 4.5% of the adult population used electronic cigarettes (e-cigarettes). Among pregnant US women who gave birth in 2016, 7.2% reported smoking cigarettes while pregnant.ObjectiveTo update its 2015 recommendation, the USPSTF commissioned a review to evaluate the benefits and harms of primary care interventions on tobacco use cessation in adults, including pregnant persons.PopulationThis recommendation statement applies to adults 18 years or older, including pregnant persons.Evidence assessmentThe USPSTF concludes with high certainty that the net benefit of behavioral interventions and US Food and Drug Associated (FDA)-approved pharmacotherapy for tobacco smoking cessation, alone or combined, in nonpregnant adults who smoke is substantial. The USPSTF concludes with high certainty that the net benefit of behavioral interventions for tobacco smoking cessation on perinatal outcomes and smoking cessation in pregnant persons is substantial. The USPSTF concludes that the evidence on pharmacotherapy interventions for tobacco smoking cessation in pregnant persons is insufficient because few studies are available, and the balance of benefits and harms cannot be determined. The USPSTF concludes that the evidence on the use of e-cigarettes for tobacco smoking cessation in adults, including pregnant persons, is insufficient, and the balance of benefits and harm

ImportanceLung cancer is the second most common cancer and the leading cause of cancer death in the US. In 2020, an estimated 228 820 persons were diagnosed with lung cancer, and 135 720 persons died of the disease. The most important risk factor for lung cancer is smoking. Increasing age is also a risk factor for lung cancer. Lung cancer has a generally poor prognosis, with an overall 5-year survival rate of 20.5%. However, early-stage lung cancer has a better prognosis and is more amenable to treatment.ObjectiveTo update its 2013 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on the accuracy of screening for lung cancer with low-dose computed tomography (LDCT) and on the benefits and harms of screening for lung cancer and commissioned a collaborative modeling study to provide information about the optimum age at which to begin and end screening, the optimal screening interval, and the relative benefits and harms of different screening strategies compared with modified versions of multivariate risk prediction models.PopulationThis recommendation statement applies to adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years.Evidence assessmentThe USPSTF concludes with moderate certainty that annual screening for lung cancer with LDCT has a moderate net benefit in persons at high risk of lung cancer based on age, total cumulative exposure to tobacco smoke, and years since quitting smoking.RecommendationThe USPSTF recommends annual screening for lung cancer with LDCT in adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery. (B recommendation) This recommendation replaces the 2013 U

ImportanceAge-related sensorineural hearing loss is a common health problem among adults. Nearly 16% of US adults 18 years or older report difficulty hearing. The prevalence of perceived hearing loss increases with age. Hearing loss can adversely affect an individual's quality of life and ability to function independently and has been associated with increased risk of falls, hospitalizations, social isolation, and cognitive decline.ObjectiveTo update its 2012 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening for hearing loss in adults 50 years or older.PopulationAsymptomatic adults 50 years or older with age-related hearing loss.Evidence assessmentBecause of a lack of evidence, the USPSTF concludes that the benefits and harms of screening for hearing loss in asymptomatic older adults are uncertain and that the balance of benefits and harms cannot be determined. More research is needed.RecommendationThe USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for hearing loss in older adults. (I statement).

ImportanceHypertension is a prevalent condition that affects approximately 45% of the adult US population and is the most commonly diagnosed condition at outpatient office visits. Hypertension is a major contributing risk factor for heart failure, myocardial infarction, stroke, and chronic kidney disease.ObjectiveTo reaffirm its 2015 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the benefits and harms of screening for hypertension in adults, the accuracy of office blood pressure measurement for initial screening, and the accuracy of various confirmatory blood pressure measurement methods.PopulationAdults 18 years or older without known hypertension.Evidence assessmentUsing a reaffirmation deliberation process, the USPSTF concludes with high certainty that screening for hypertension in adults has substantial net benefit.RecommendationThe USPSTF recommends screening for hypertension in adults 18 years or older with office blood pressure measurement. The USPSTF recommends obtaining blood pressure measurements outside of the clinical setting for diagnostic confirmation before starting treatment. (A recommendation).

ImportanceVitamin D is a fat-soluble vitamin that performs an important role in calcium homeostasis and bone metabolism and also affects many other cellular regulatory functions outside the skeletal system. Vitamin D requirements may vary by individual; thus, no one serum vitamin D level cutpoint defines deficiency, and no consensus exists regarding the precise serum levels of vitamin D that represent optimal health or sufficiency.ObjectiveTo update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening for vitamin D deficiency, including the benefits and harms of screening and early treatment.PopulationCommunity-dwelling, nonpregnant adults who have no signs or symptoms of vitamin D deficiency or conditions for which vitamin D treatment is recommended.Evidence assessmentThe USPSTF concludes that the overall evidence on the benefits of screening for vitamin D deficiency is lacking. Therefore, the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults cannot be determined.RecommendationThe USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults. (I statement).

ImportanceThe prevalence of overweight and obesity is increasing among persons of childbearing age and pregnant persons. In 2015, almost half of all persons began pregnancy with overweight (24%) or obesity (24%). Reported rates of overweight and obesity are higher among Black, Alaska Native/American Indian, and Hispanic women and lower among White and Asian women. Excess weight at the beginning of pregnancy and excess gestational weight gain have been associated with adverse maternal and infant health outcomes such as a large for gestational age infant, cesarean delivery, or preterm birth.ObjectiveThe USPSTF commissioned a systematic review to evaluate the benefits and harms of behavioral counseling interventions to prevent adverse health outcomes associated with obesity during pregnancy and to evaluate intermediate outcomes, including excess gestational weight gain. This is a new recommendation.PopulationPregnant adolescents and adults in primary care settings.Evidence assessmentThe USPSTF concludes with moderate certainty that behavioral counseling interventions aimed at promoting healthy weight gain and preventing excess gestational weight gain in pregnancy have a moderate net benefit for pregnant persons.RecommendationThe USPSTF recommends that clinicians offer pregnant persons effective behavioral counseling interventions aimed at promoting healthy weight gain and preventing excess gestational weight gain in pregnancy. (B recommendation).

ImportanceColorectal cancer is the third leading cause of cancer death for both men and women, with an estimated 52 980 persons in the US projected to die of colorectal cancer in 2021. Colorectal cancer is most frequently diagnosed among persons aged 65 to 74 years. It is estimated that 10.5% of new colorectal cancer cases occur in persons younger than 50 years. Incidence of colorectal cancer (specifically adenocarcinoma) in adults aged 40 to 49 years has increased by almost 15% from 2000-2002 to 2014-2016. In 2016, 26% of eligible adults in the US had never been screened for colorectal cancer and in 2018, 31% were not up to date with screening.ObjectiveTo update its 2016 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the benefits and harms of screening for colorectal cancer in adults 40 years or older. The review also examined whether these findings varied by age, sex, or race/ethnicity. In addition, as in 2016, the USPSTF commissioned a report from the Cancer Intervention and Surveillance Modeling Network Colorectal Cancer Working Group to provide information from comparative modeling on how estimated life-years gained, colorectal cancer cases averted, and colorectal cancer deaths averted vary by different starting and stopping ages for various screening strategies.PopulationAsymptomatic adults 45 years or older at average risk of colorectal cancer (ie, no prior diagnosis of colorectal cancer, adenomatous polyps, or inflammatory bowel disease; no personal diagnosis or family history of known genetic disorders that predispose them to a high lifetime risk of colorectal cancer [such as Lynch syndrome or familial adenomatous polyposis]).Evidence assessmentThe USPSTF concludes with high certainty that screening for colorectal cancer in adults aged 50 to 75 years has substantial net benefit. The USPSTF concludes with moderate certainty that screening for colorectal cancer in adults aged 45 to 49 years has mode

Importance:Dementia (also known as major neurocognitive disorder) is defined by a significant decline in 1 or more cognitive domains that interferes with a person's independence in daily activities. Dementia affects an estimated 2.4 to 5.5 million individuals in the United States, and its prevalence increases with age. Objective:To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on screening for cognitive impairment, including mild cognitive impairment and mild to moderate dementia, in community-dwelling adults, including those 65 years or older residing in independent living facilities. Population:This recommendation applies to community-dwelling older adults 65 years or older, without recognized signs or symptoms of cognitive impairment. Evidence Assessment:The USPSTF concludes that the evidence is lacking, and the balance of benefits and harms of screening for cognitive impairment cannot be determined. Recommendation:The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for cognitive impairment in older adults. (I statement).

Importance:In 2017, an estimated 7.9% of persons aged 12 to 17 years reported illicit drug use in the past month, and an estimated 50% of adolescents in the US had used an illicit drug by the time they graduated from high school. Young adults aged 18 to 25 years have a higher rate of current illicit drug use, with an estimated 23.2% currently using illicit drugs. Illicit drug use is associated with many negative health, social, and economic consequences and is a significant contributor to 3 of the leading causes of death among young persons (aged 10-24 years): unintentional injuries including motor vehicle crashes, suicide, and homicide. Objective:To update its 2014 recommendation, the USPSTF commissioned a review of the evidence on the potential benefits and harms of interventions to prevent illicit drug use in children, adolescents, and young adults. Population:This recommendation applies to children (11 years and younger), adolescents (aged 12-17 years), and young adults (aged 18-25 years), including pregnant persons. Evidence Assessment:Because of limited and inadequate evidence, the USPSTF concludes that the benefits and harms of primary care-based interventions to prevent illicit drug use in children, adolescents, and young adults are uncertain and that the evidence is insufficient to assess the balance of benefits and harms. More research is needed. Recommendation:The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of primary care-based behavioral counseling interventions to prevent illicit drug use, including nonmedical use of prescription drugs, in children, adolescents, and young adults. (I statement).

ImportanceAn estimated 12% of adults 18 years or older and 8% of adolescents aged 12 to 17 years report unhealthy use of prescription or illegal drugs in the US.ObjectiveTo update its 2008 recommendation, the USPSTF commissioned reviews of the evidence on screening by asking questions about drug use and interventions for unhealthy drug use in adults and adolescents.PopulationThis recommendation statement applies to adults 18 years or older, including pregnant and postpartum persons, and adolescents aged 12 to 17 years in primary care settings. This statement does not apply to adolescents or adults who have a currently diagnosed drug use disorder or are currently undergoing or have been referred for drug use treatment. This statement applies to settings and populations for which services for accurate diagnosis, effective treatment, and appropriate care can be offered or referred.Evidence assessmentIn adults, the USPSTF concludes with moderate certainty that screening by asking questions about unhealthy drug use has moderate net benefit when services for accurate diagnosis of unhealthy drug use or drug use disorders, effective treatment, and appropriate care can be offered or referred. In adolescents, because of the lack of evidence, the USPSTF concludes that the benefits and harms of screening for unhealthy drug use are uncertain and that the balance of benefits and harms cannot be determined.RecommendationThe USPSTF recommends screening by asking questions about unhealthy drug use in adults 18 years or older. Screening should be implemented when services for accurate diagnosis, effective treatment, and appropriate care can be offered or referred. (Screening refers to asking questions about unhealthy drug use, not testing biological specimens.) (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for unhealthy drug use in adolescents. (I statement).

Importance:Approximately 20 million new cases of bacterial or viral sexually transmitted infections (STIs) occur each year in the US, and about one-half of these cases occur in persons aged 15 to 24 years. Rates of chlamydial, gonococcal, and syphilis infection continue to increase in all regions. Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others. Serious consequences of STIs include pelvic inflammatory disease, infertility, cancer, and AIDS. Objective:To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on the benefits and harms of behavioral counseling interventions for preventing STI acquisition. Population:This recommendation statement applies to all sexually active adolescents and to adults at increased risk for STIs. Evidence Assessment:The USPSTF concludes with moderate certainty that behavioral counseling interventions reduce the likelihood of acquiring STIs in sexually active adolescents and in adults at increased risk, including for example, those who have a current STI, do not use condoms, or have multiple partners, resulting in a moderate net benefit. Recommendation:The USPSTF recommends behavioral counseling for all sexually active adolescents and for adults at increased risk for STIs. (B recommendation).

ImportanceCardiovascular disease (CVD) is a leading cause of death in the US. Known modifiable risk factors for CVD include smoking, overweight and obesity, diabetes, elevated blood pressure or hypertension, dyslipidemia, lack of physical activity, and unhealthy diet. Adults who adhere to national guidelines for a healthy diet and physical activity have lower cardiovascular morbidity and mortality than those who do not. All persons, regardless of their CVD risk status, benefit from healthy eating behaviors and appropriate physical activity.ObjectiveTo update its 2014 recommendation, the USPSTF commissioned a review of the evidence on behavioral counseling to promote a healthy diet and physical activity for CVD prevention in adults with cardiovascular risk factors.PopulationThis recommendation statement applies to adults 18 years or older with known hypertension or elevated blood pressure, those with dyslipidemia, or those who have mixed or multiple risk factors such as metabolic syndrome or an estimated 10-year CVD risk of 7.5% or greater. Adults with other known modifiable cardiovascular risk factors such as abnormal blood glucose levels, obesity, and smoking are not included in this recommendation.Evidence assessmentThe USPSTF concludes with moderate certainty that behavioral counseling interventions have a moderate net benefit on CVD risk in adults at increased risk for CVD.RecommendationThe USPSTF recommends offering or referring adults with CVD risk factors to behavioral counseling interventions to promote a healthy diet and physical activity. (B recommendation).

ImportancePrevalence of hypertension (both primary and secondary) in children and adolescents in the US ranges from 3% to 4%. Primary hypertension in children and adolescents occurs primarily in children older than 13 years and has no known cause but is associated with several risk factors, including family history and higher body mass index. Secondary hypertension occurs primarily in younger children and is most commonly caused by genetic disorders, renal disease, endocrine disorders, or cardiovascular abnormalities.ObjectiveTo update its 2013 recommendation, the USPSTF commissioned a review of the evidence on the benefits and harms of screening, test accuracy, the effectiveness and harms of treatment, and the association between hypertension and markers of cardiovascular disease in childhood and adulthood.PopulationThis recommendation statement applies to children and adolescents aged 3 to 18 years not known to have hypertension or who are asymptomatic.Evidence assessmentThe USPSTF concludes that the evidence to support screening for high blood pressure in children and adolescents is insufficient and that the balance of benefits and harms cannot be determined.RecommendationThe USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for high blood pressure in children and adolescents.

Dementia affects an estimated 2.4 to 5.5 million individuals in the United States, and its prevalence increases with age. Objective:To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on screening for cognitive impairment, including mild cognitive impairment and mild to moderate dementia, in community-dwelling adults, including those 65 years or older residing in independent living facilities. Population:This recommendation applies to community-dwelling older adults 65 years or older, without recognized signs or symptoms of cognitive impairment. Evidence Assessment:The USPSTF concludes that the evidence is lacking, and the balance of benefits and harms of screening for cognitive impairment cannot be determined. Recommendation:The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for cognitive impairment in older adults. (I statement).

Importance:In 2017, an estimated 7.9% of persons aged 12 to 17 years reported illicit drug use in the past month, and an estimated 50% of adolescents in the US had used an illicit drug by the time they graduated from high school. Young adults aged 18 to 25 years have a higher rate of current illicit drug use, with an estimated 23.2% currently using illicit drugs. Illicit drug use is associated with many negative health, social, and economic consequences and is a significant contributor to 3 of the leading causes of death among young persons (aged 10-24 years): unintentional injuries including motor vehicle crashes, suicide, and homicide. Objective:To update its 2014 recommendation, the USPSTF commissioned a review of the evidence on the potential benefits and harms of interventions to prevent illicit drug use in children, adolescents, and young adults. Population:This recommendation applies to children (11 years and younger), adolescents (aged 12-17 years), and young adults (aged 18-25 years), including pregnant persons. Evidence Assessment:Because of limited and inadequate evidence, the USPSTF concludes that the benefits and harms of primary care-based interventions to prevent illicit drug use in children, adolescents, and young adults are uncertain and that the evidence is insufficient to assess the balance of benefits and harms. More research is needed. Recommendation:The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of primary care-based behavioral counseling interventions to prevent illicit drug use, including nonmedical use of prescription drugs, in children, adolescents, and young adults. (I statement).

Importance:Approximately 20 million new cases of bacterial or viral sexually transmitted infections (STIs) occur each year in the US, and about one-half of these cases occur in persons aged 15 to 24 years. Rates of chlamydial, gonococcal, and syphilis infection continue to increase in all regions. Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others. Serious consequences of STIs include pelvic inflammatory disease, infertility, cancer, and AIDS. Objective:To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on the benefits and harms of behavioral counseling interventions for preventing STI acquisition. Population:This recommendation statement applies to all sexually active adolescents and to adults at increased risk for STIs. Evidence Assessment:The USPSTF concludes with moderate certainty that behavioral counseling interventions reduce the likelihood of acquiring STIs in sexually active adolescents and in adults at increased risk, including for example, those who have a current STI, do not use condoms, or have multiple partners, resulting in a moderate net benefit. Recommendation:The USPSTF recommends behavioral counseling for all sexually active adolescents and for adults at increased risk for STIs. (B recommendation).

ImportanceAn estimated 12% of adults 18 years or older and 8% of adolescents aged 12 to 17 years report unhealthy use of prescription or illegal drugs in the US.ObjectiveTo update its 2008 recommendation, the USPSTF commissioned reviews of the evidence on screening by asking questions about drug use and interventions for unhealthy drug use in adults and adolescents.PopulationThis recommendation statement applies to adults 18 years or older, including pregnant and postpartum persons, and adolescents aged 12 to 17 years in primary care settings. This statement does not apply to adolescents or adults who have a currently diagnosed drug use disorder or are currently undergoing or have been referred for drug use treatment. This statement applies to settings and populations for which services for accurate diagnosis, effective treatment, and appropriate care can be offered or referred.Evidence assessmentIn adults, the USPSTF concludes with moderate certainty that screening by asking questions about unhealthy drug use has moderate net benefit when services for accurate diagnosis of unhealthy drug use or drug use disorders, effective treatment, and appropriate care can be offered or referred. In adolescents, because of the lack of evidence, the USPSTF concludes that the benefits and harms of screening for unhealthy drug use are uncertain and that the balance of benefits and harms cannot be determined.RecommendationThe USPSTF recommends screening by asking questions about unhealthy drug use in adults 18 years or older. Screening should be implemented when services for accurate diagnosis, effective treatment, and appropriate care can be offered or referred. (Screening refers to asking questions about unhealthy drug use, not testing biological specimens.) (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for unhealthy drug use in adolescents. (I statement).

ImportancePotentially harmful mutations of the breast cancer susceptibility 1 and 2 genes (BRCA1/2) are associated with increased risk for breast, ovarian, fallopian tube, and peritoneal cancer. For women in the United States, breast cancer is the most common cancer after nonmelanoma skin cancer and the second leading cause of cancer death. In the general population, BRCA1/2 mutations occur in an estimated 1 in 300 to 500 women and account for 5% to 10% of breast cancer cases and 15% of ovarian cancer cases.ObjectiveTo update the 2013 US Preventive Services Task Force (USPSTF) recommendation on risk assessment, genetic counseling, and genetic testing for BRCA-related cancer.Evidence reviewThe USPSTF reviewed the evidence on risk assessment, genetic counseling, and genetic testing for potentially harmful BRCA1/2 mutations in asymptomatic women who have never been diagnosed with BRCA-related cancer, as well as those with a previous diagnosis of breast, ovarian, tubal, or peritoneal cancer who have completed treatment and are considered cancer free. In addition, the USPSTF reviewed interventions to reduce the risk for breast, ovarian, tubal, or peritoneal cancer in women with potentially harmful BRCA1/2 mutations, including intensive cancer screening, medications, and risk-reducing surgery.FindingsFor women whose family or personal history is associated with an increased risk for harmful mutations in the BRCA1/2 genes, or who have an ancestry associated with BRCA1/2 gene mutations, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are moderate. For women whose personal or family history or ancestry is not associated with an increased risk for harmful mutations in the BRCA1/2 genes, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are small to none. Regardless of family or personal history, the USPSTF found adequate evidence that t

ImportanceIn the United States, the rate of gonococcal ophthalmia neonatorum was an estimated 0.4 cases per 100 000 live births per year from 2013 to 2017. Gonococcal ophthalmia neonatorum can cause corneal scarring, ocular perforation, and blindness as early as 24 hours after birth. In the absence of ocular prophylaxis, transmission rates of gonococcal infection from mother to newborn are 30% to 50%.ObjectiveTo reaffirm the US Preventive Services Task Force (USPSTF) 2011 recommendation on ocular prophylaxis for gonococcal ophthalmia neonatorum.Evidence reviewThe USPSTF commissioned a reaffirmation evidence update to identify new and substantial evidence sufficient enough to change its prior recommendation.FindingsUsing a reaffirmation process, the USPSTF found no new data that would change its previous conclusion that topical ocular prophylaxis is effective in preventing gonococcal ophthalmia neonatorum and related ocular conditions. The USPSTF found no new data that would change its previous conclusion that there is convincing evidence that topical ocular prophylaxis of all newborns is not associated with serious harms. Therefore, the USPSTF reaffirms its previous conclusion that there is convincing evidence that topical ocular prophylaxis for all newborns provides substantial benefit.Conclusions and recommendationThe USPSTF recommends prophylactic ocular topical medication for all newborns to prevent gonococcal ophthalmia neonatorum. (A recommendation).

ImportancePerinatal depression, which is the occurrence of a depressive disorder during pregnancy or following childbirth, affects as many as 1 in 7 women and is one of the most common complications of pregnancy and the postpartum period. It is well established that perinatal depression can result in adverse short- and long-term effects on both the woman and child.ObjectiveTo issue a new US Preventive Services Task Force (USPSTF) recommendation on interventions to prevent perinatal depression.Evidence reviewThe USPSTF reviewed the evidence on the benefits and harms of preventive interventions for perinatal depression in pregnant or postpartum women or their children. The USPSTF reviewed contextual information on the accuracy of tools used to identify women at increased risk of perinatal depression and the most effective timing for preventive interventions. Interventions reviewed included counseling, health system interventions, physical activity, education, supportive interventions, and other behavioral interventions, such as infant sleep training and expressive writing. Pharmacological approaches included the use of nortriptyline, sertraline, and omega-3 fatty acids.FindingsThe USPSTF found convincing evidence that counseling interventions, such as cognitive behavioral therapy and interpersonal therapy, are effective in preventing perinatal depression. Women with a history of depression, current depressive symptoms, or certain socioeconomic risk factors (eg, low income or young or single parenthood) would benefit from counseling interventions and could be considered at increased risk. The USPSTF found adequate evidence to bound the potential harms of counseling interventions as no greater than small, based on the nature of the intervention and the low likelihood of serious harms. The USPSTF found inadequate evidence to assess the benefits and harms of other noncounseling interventions. The USPSTF concludes with moderate certainty that providing or referring pregnan

ImportanceApproximately 1.1 million persons in the United States are currently living with HIV, and more than 700 000 persons have died of AIDS since the first cases were reported in 1981. There were approximately 38 300 new diagnoses of HIV infection in 2017. The estimated prevalence of HIV infection among persons 13 years and older in the United States is 0.4%, and data from the Centers for Disease Control and Prevention show a significant increase in HIV diagnoses starting at age 15 years. An estimated 8700 women living with HIV give birth each year in the United States. HIV can be transmitted from mother to child during pregnancy, labor, delivery, and breastfeeding. The incidence of perinatal HIV infection in the United States peaked in 1992 and has declined significantly following the implementation of routine prenatal HIV screening and the use of effective therapies and precautions to prevent mother-to-child transmission.ObjectiveTo update the 2013 US Preventive Services Task Force (USPSTF) recommendation on screening for HIV infection in adolescents, adults, and pregnant women.Evidence reviewThe USPSTF reviewed the evidence on the benefits and harms of screening for HIV infection in nonpregnant adolescents and adults, the yield of screening for HIV infection at different intervals, the effects of initiating antiretroviral therapy (ART) at a higher vs lower CD4 cell count, and the longer-term harms associated with currently recommended ART regimens. The USPSTF also reviewed the evidence on the benefits (specifically, reduced risk of mother-to-child transmission of HIV infection) and harms of screening for HIV infection in pregnant persons, the yield of repeat screening for HIV at different intervals during pregnancy, the effectiveness of currently recommended ART regimens for reducing mother-to-child transmission of HIV infection, and the harms of ART during pregnancy to the mother and infant.FindingsThe USPSTF found convincing evidence that currently recommen

ImportanceAn estimated 1.1 million individuals in the United States are currently living with HIV, and more than 700 000 persons have died of AIDS since the first cases were reported in 1981. In 2017, there were 38 281 new diagnoses of HIV infection reported in the United States; 81% of these new diagnoses were among males and 19% were among females. Although treatable, HIV infection has no cure and has significant health consequences.ObjectiveTo issue a new US Preventive Services Task Force (USPSTF) recommendation on preexposure prophylaxis (PrEP) for the prevention of HIV infection.Evidence reviewThe USPSTF reviewed the evidence on the benefits of PrEP for the prevention of HIV infection with oral tenofovir disoproxil fumarate monotherapy or combined tenofovir disoproxil fumarate and emtricitabine and whether the benefits vary by risk group, population subgroup, or regimen or dosing strategy; the diagnostic accuracy of risk assessment tools to identify persons at high risk of HIV acquisition; the rates of adherence to PrEP in primary care settings; the association between adherence and effectiveness of PrEP; and the harms of PrEP when used for HIV prevention.FindingsThe USPSTF found convincing evidence that PrEP is of substantial benefit in decreasing the risk of HIV infection in persons at high risk of HIV acquisition. The USPSTF also found convincing evidence that adherence to PrEP is highly associated with its efficacy in preventing the acquisition of HIV infection; thus, adherence to PrEP is central to realizing its benefit. The USPSTF found adequate evidence that PrEP is associated with small harms, including kidney and gastrointestinal adverse effects. The USPSTF concludes with high certainty that the magnitude of benefit of PrEP with oral tenofovir disoproxil fumarate-based therapy to reduce the risk of acquisition of HIV infection in persons at high risk is substantial.Conclusions and recommendationThe USPSTF recommends offering PrEP with effective antiret

ImportanceScreening for hepatitis B virus (HBV) infection during pregnancy identifies women whose infants are at risk of perinatal transmission. Data from a nationally representative sample showed a prevalence of maternal HBV infection of 85.8 cases per 100 000 deliveries from 1998 to 2011 (0.09% of live-born singleton deliveries in the United States). Although there are guidelines for universal infant HBV vaccination, rates of maternal HBV infection have increased annually by 5.5% since 1998. Children infected with HBV during infancy or childhood are more likely to develop chronic infection. Chronic HBV infection increases long-term morbidity and mortality by predisposing infected persons to cirrhosis of the liver and liver cancer.ObjectiveTo update the 2009 US Preventive Services Task Force (USPSTF) recommendation on screening for HBV infection in pregnant women.Evidence reviewThe USPSTF commissioned a reaffirmation evidence update to identify substantial new evidence sufficient enough to change the prior recommendation. The USPSTF targeted its evidence review on the effectiveness and potential harms of screening and the effectiveness and harms of case management to prevent perinatal transmission.FindingsThe USPSTF previously found adequate evidence that serologic testing for hepatitis B surface antigen accurately identifies HBV infection. Interventions are effective for preventing perinatal transmission, based on foundational evidence and observational studies of US case management programs. In addition, there is evidence that over time, perinatal transmission has decreased among women and infants enrolled in case management, providing an overall substantial health benefit. Therefore, the USPSTF reaffirms its previous conclusion that there is convincing evidence that screening for HBV infection in pregnant women provides substantial benefit.Conclusions and recommendationThe USPSTF recommends screening for HBV infection in pregnant women at their first prenatal vi

ImportancePancreatic cancer is an uncommon cancer with an age-adjusted annual incidence of 12.9 cases per 100 000 person-years. However, the death rate is 11.0 deaths per 100 000 person-years because the prognosis of pancreatic cancer is poor. Although its incidence is low, pancreatic cancer is the third most common cause of cancer death in the United States. Because of the increasing incidence of pancreatic cancer, along with improvements in early detection and treatment of other types of cancer, it is estimated that pancreatic cancer may soon become the second-leading cause of cancer death in the United States.ObjectiveTo update the 2004 US Preventive Services Task Force (USPSTF) recommendation on screening for pancreatic cancer.Evidence reviewThe USPSTF reviewed the evidence on the benefits and harms of screening for pancreatic cancer, the diagnostic accuracy of screening tests for pancreatic cancer, and the benefits and harms of treatment of screen-detected or asymptomatic pancreatic cancer.FindingsThe USPSTF found no evidence that screening for pancreatic cancer or treatment of screen-detected pancreatic cancer improves disease-specific morbidity or mortality, or all-cause mortality. The USPSTF found adequate evidence that the magnitude of the benefits of screening for pancreatic cancer in asymptomatic adults can be bounded as no greater than small. The USPSTF found adequate evidence that the magnitude of the harms of screening for pancreatic cancer and treatment of screen-detected pancreatic cancer can be bounded as at least moderate. The USPSTF reaffirms its previous conclusion that the potential benefits of screening for pancreatic cancer in asymptomatic adults do not outweigh the potential harms.Conclusions and recommendationThe USPSTF recommends against screening for pancreatic cancer in asymptomatic adults. (D recommendation).

Importance:Breast cancer is the most common nonskin cancer among women in the United States and the second leading cause of cancer death. The median age at diagnosis is 62 years, and an estimated 1 in 8 women will develop breast cancer at some point in their lifetime. African American women are more likely to die of breast cancer compared with women of other races. Objective:To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on medications for risk reduction of primary breast cancer. Evidence Review:The USPSTF reviewed evidence on the accuracy of risk assessment methods to identify women who could benefit from risk-reducing medications for breast cancer, as well as evidence on the effectiveness, adverse effects, and subgroup variations of these medications. The USPSTF reviewed evidence from randomized trials, observational studies, and diagnostic accuracy studies of risk stratification models in women without preexisting breast cancer or ductal carcinoma in situ. Findings:The USPSTF found convincing evidence that risk assessment tools can predict the number of cases of breast cancer expected to develop in a population. However, these risk assessment tools perform modestly at best in discriminating between individual women who will or will not develop breast cancer. The USPSTF found convincing evidence that risk-reducing medications (tamoxifen, raloxifene, or aromatase inhibitors) provide at least a moderate benefit in reducing risk for invasive estrogen receptor-positive breast cancer in postmenopausal women at increased risk for breast cancer. The USPSTF found that the benefits of taking tamoxifen, raloxifene, and aromatase inhibitors to reduce risk for breast cancer are no greater than small in women not at increased risk for the disease. The USPSTF found convincing evidence that tamoxifen and raloxifene and adequate evidence that aromatase inhibitors are associated with small to moderate harms. Overall, the USPSTF determined that the net

Importance:Among the general adult population, women (across all ages) have the highest prevalence of asymptomatic bacteriuria, although rates increase with age among both men and women. Asymptomatic bacteriuria is present in an estimated 1% to 6% of premenopausal women and an estimated 2% to 10% of pregnant women and is associated with pyelonephritis, one of the most common nonobstetric reasons for hospitalization in pregnant women. Among pregnant persons, pyelonephritis is associated with perinatal complications including septicemia, respiratory distress, low birth weight, and spontaneous preterm birth. Objective:To update its 2008 recommendation, the USPSTF commissioned a review of the evidence on potential benefits and harms of screening for and treatment of asymptomatic bacteriuria in adults, including pregnant persons. Population:This recommendation applies to community-dwelling adults 18 years and older and pregnant persons of any age without signs and symptoms of a urinary tract infection. Evidence Assessment:Based on a review of the evidence, the USPSTF concludes with moderate certainty that screening for and treatment of asymptomatic bacteriuria in pregnant persons has moderate net benefit in reducing perinatal complications. There is adequate evidence that pyelonephritis in pregnancy is associated with negative maternal outcomes and that treatment of screen-detected asymptomatic bacteriuria can reduce the incidence of pyelonephritis in pregnant persons. The USPSTF found adequate evidence of harms associated with treatment of asymptomatic bacteriuria (including adverse effects of antibiotic treatment and changes in the microbiome) to be at least small in magnitude. The USPSTF concludes with moderate certainty that screening for and treatment of asymptomatic bacteriuria in nonpregnant adults has no net benefit. The known harms associated with treatment include adverse effects of antibiotic use and changes to the microbiome. Based on these known harms, the U

Importance:An abdominal aortic aneurysm (AAA) is typically defined as aortic enlargement with a diameter of 3.0 cm or larger. The prevalence of AAA has declined over the past 2 decades among screened men 65 years or older in various European countries. The current prevalence of AAA in the United States is unclear because of the low uptake of screening. Most AAAs are asymptomatic until they rupture. Although the risk for rupture varies greatly by aneurysm size, the associated risk for death with rupture is as high as 81%. Objective:To update its 2014 recommendation, the USPSTF commissioned a review of the evidence on the effectiveness of 1-time and repeated screening for AAA, the associated harms of screening, and the benefits and harms of available treatments for small AAAs (3.0-5.4 cm in diameter) identified through screening. Population:This recommendation applies to asymptomatic adults 50 years or older. However, the randomized trial evidence focuses almost entirely on men aged 65 to 75 years. Evidence Assessment:Based on a review of the evidence, the USPSTF concludes with moderate certainty that screening for AAA in men aged 65 to 75 years who have ever smoked is of moderate net benefit. The USPSTF concludes with moderate certainty that screening for AAA in men aged 65 to 75 years who have never smoked is of small net benefit. The USPSTF concludes that the evidence is insufficient to determine the net benefit of screening for AAA in women aged 65 to 75 years who have ever smoked or have a family history of AAA. The USPSTF concludes with moderate certainty that the harms of screening for AAA in women aged 65 to 75 years who have never smoked and have no family history of AAA outweigh the benefits. Recommendations:The USPSTF recommends 1-time screening for AAA with ultrasonography in men aged 65 to 75 years who have ever smoked.
