While the prognosis for abdominal aortic aneurysm (AAA) rupture is poor, ultrasound imaging is an accurate and reliable test for detecting AAAs before rupture.
To examine the benefits and harms of ...population-based AAA screening.
MEDLINE (1994 to July 2004) supplemented by the Cochrane Library, a reference list of retrieved articles, and expert suggestions.
Randomized trials of AAA population screening, population studies of AAA risk factors, and data on adverse screening and treatment events from randomized trials and cohort studies.
All studies were reviewed, abstracted, and rated for quality by using predefined criteria.
The authors identified 4 population-based randomized, controlled trials of AAA screening in men 65 years of age and older. On the basis of meta-analysis, an invitation to attend screening was associated with a significant reduction in AAA-related mortality (odds ratio, 0.57 95% CI, 0.45 to 0.74). A meta-analysis of 3 trials revealed no significant difference in all-cause mortality (odds ratio, 0.98 CI, 0.95 to 1.02). No significant reduction in AAA-related mortality was found in 1 study of AAA screening in women. Screening does not appear to be associated with significant physical or psychological harms. Major treatment harms include an operative mortality rate of 2% to 6% and significant risk for major complications.
The population screening studies focused on men and provided no information on racial or ethnic groups. No information was available on uninvited control group characteristics, so the importance of risk factors such as tobacco use or family history could not be assessed. Since all trials were conducted in countries other than the United States, generalizability to the U.S. population is uncertain.
For men age 65 to 75 years, an invitation to attend AAA screening reduces AAA-related mortality.
Objective:
This study estimated the prevalence of diagnosed depression and treatment among women before, during, and after pregnancies ending in live births.
Method:
A previously validated algorithm ...identified health plan members with at least one pregnancy between Jan. 1, 1998, and Dec. 31, 2001. Women with a pregnancy ending in one or more live births and continuously enrolled from 39 weeks before pregnancy through 39 weeks after pregnancy were eligible. Maternal depression was identified from the medical records. Depression treatment included antidepressant medication and or mental health visits. The authors examined the prevalence of depression and treatments received.
Results:
Among 4,398 continuously enrolled women with eligible pregnancies ending in live births, 678 (15.4%) had depression identified during at least one pregnancy phase; 8.7%, 6.9%, and 10.4% had depression identified before, during, and or after pregnancy, respectively. Among women with identified depression during the 39 weeks before pregnancy, 56.4% also had a depression diagnosis during pregnancy. Of women identified with depression during the 39 weeks following pregnancy, 54.2% had depression diagnoses either during or preceding pregnancy. Most women diagnosed with depression received antidepressant medications and or had at least one mental health visit. Having at least one mental health visit did not vary before, during, or after pregnancy; however, antidepressant use was lower during pregnancy than before or after pregnancy.
Conclusions:
Approximately one in seven women was identified with and treated for depression during 39 weeks before through 39 weeks after pregnancy, and more than half of these women had recurring indicators for depression.
In primary care settings, prevalence estimates of major depressive disorder range from 5% to 13% in all adults, with lower estimates in those older than 55 years (6% to 9%). In 2002, the U.S. ...Preventive Services Task Force (USPSTF) recommended screening adults for depression in clinical practices that have systems to ensure accurate diagnosis, effective treatment, and follow-up.
To conduct a targeted, updated systematic review for the U.S. Preventive Services Task Force about the benefits and harms of screening adult patients for depression in a primary care setting, the benefits of depression treatment in older adults, and the harms of depression treatment with antidepressant medications.
MEDLINE, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, PsycINFO (1998 to 2007), expert suggestions, and bibliographies of recent systematic reviews.
Fair- to good-quality randomized clinical trials or controlled clinical trials; systematic reviews; meta-analyses; and large observational studies of serious adverse events and early discontinuation due to adverse effects. All studies were published in English.
Two investigators abstracted, critically appraised, and synthesized 33 articles that met inclusion criteria.
Nine fair- or good-quality trials indicate that primary care depression screening and care management programs with staff assistance, such as case management or mental health specialist involvement, can increase depression response and remission. Benefit was not evident in screening programs without staff assistance in depression care. Seven regulatory reviews or meta-analyses and 3 large cohort studies indicate no increased risk for completed suicide deaths with antidepressant treatment. Risk for suicidal behaviors was increased in young adults (aged 18 to 29 years) who received antidepressants, particularly those who received paroxetine, but was reduced in older adults.
Examination of harms was limited to serious adverse events, and existing systematic reviews were primarily used. Additional studies published from 2007 to 2008 extend this review.
Depression screening programs without substantial staff-assisted depression care supports are unlikely to improve depression outcomes. Close monitoring of all adult patients who initiate antidepressant treatment, particularly those younger than 30 years, is important both for safety and to ensure optimal treatment.
Depression among youth is a disabling condition that is associated with serious long-term morbidities and suicide.
To assess the health effects of routine primary care screening for major depressive ...disorder among children and adolescents aged 7 to 18 years.
Medline, the Cochrane Central Registry of Controlled Trials, PsycInfo, the Cochrane Database of Systematic Reviews, recent systematic reviews, experts, and bibliographies from selected studies were the data sources. The studies selected were fair- and good-quality (on the basis of US Preventive Services Task Force criteria) controlled trials of screening and treatment (selective serotonin reuptake inhibitor and/or psychotherapy), diagnostic accuracy studies, and large observational studies that reported adverse events. Two reviewers quality-graded each article. One reviewer abstracted relevant information into standardized evidence tables, and a second reviewer checked key elements.
We found no data describing health outcomes among screened and unscreened populations. Although the literature on diagnostic screening test accuracy is small and methodologically limited, it indicates that several screening instruments have performed fairly well among adolescents. The literature on treatment efficacy of selective serotonin reuptake inhibitors and/or psychotherapy is also small but includes good-quality randomized, controlled trials. Available data indicate that selective serotonin reuptake inhibitors, psychotherapy, and combined treatment are effective in increasing response rates and reducing depressive symptoms. Not all specific selective serotonin reuptake inhibitors, however, seem to be efficacious. Selective serotonin reuptake inhibitor treatment was associated with a small absolute increase in risk of suicidality (ie, suicidal ideation, preparatory acts, or attempts). No suicide deaths occurred in any of the trials. CONCLUSIONS. Limited available data suggest that primary care-feasible screening tools may accurately identify depressed adolescents and treatment can improve depression outcomes. Treating depressed youth with selective serotonin reuptake inhibitors may be associated with a small increased risk of suicidality and should only be considered if judicious clinical monitoring is possible.
IMPORTANCE: Multifactorial dyslipidemia, characterized by elevated total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C), is associated with dyslipidemia and markers of ...atherosclerosis in young adulthood. Screening for dyslipidemia in childhood could delay or reduce cardiovascular events in adulthood. OBJECTIVE: To systematically review the evidence on benefits and harms of screening adolescents and children for multifactorial dyslipidemia for the US Preventive Services Task Force (USPSTF). DATA SOURCES: MEDLINE, Cochrane Central Register of Controlled Trials, and PubMed were searched for studies published between January 1, 2005, and June 2, 2015; studies included in a previous USPSTF evidence report and reference lists of relevant studies and ongoing trials were also searched. Surveillance was conducted through April 9, 2016. STUDY SELECTION: Fair- and good-quality studies in English with participants 0 to 20 years of age. DATA EXTRACTION AND SYNTHESIS: Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. MAIN OUTCOMES AND MEASURES: Outcomes included dyslipidemia (TC≥200 mg/dL or LDL-C≥130 mg/dL) and atherosclerosis in childhood; myocardial infarction and ischemic stroke in adulthood; diagnostic yield (number of confirmed cases per children screened); and harms of screening or treatment. Simulated diagnostic yield was calculated as initial screening yield × positive predictive value from a study with confirmatory testing. RESULTS: Screening of children for multifactorial dyslipidemia has not been evaluated in randomized clinical trials. Based on 1 observational study (n = 6500) and nationally representative prevalence estimates, the simulated diagnostic yield of screening for elevated TC varies between 4.8% and 12.3% (higher in obese children 12.3% and at the ages when TC naturally peaks—7.2% at age 9-11 years and 7.2% at age 16-19 years). One good-quality randomized clinical trial (n = 663) found a modest effect of intensive dietary counseling for a low-fat, low-cholesterol diet on lipid levels at 1 year in children aged 8 to 10 years with mild to moderate dyslipidemia; mean between-group difference in TC change from baseline was −6.1 mg/dL (95% CI, −9.1 to −3.2 mg/dL; P < .001). Between-group differences dissipated by year 5. The intervention did not adversely affect nutritional status, growth, or development over the 18-year study period. One observational study (n = 9245) found that TC concentration at age 12 to 39 years was not associated with death before age 55 years. CONCLUSIONS AND RELEVANCE: The diagnostic yield of lipid screening varies by age and body mass index. No direct evidence was identified for benefits or harms of childhood screening or treatment on outcomes in adulthood. Intensive dietary interventions may be safe, with modest short-term benefit of uncertain clinical significance.
Despite the success of cervical cancer screening programs, questions remain about the appropriate time to begin and end screening. This review explores epidemiologic and contextual data on cervical ...cancer screening to inform decisions about when screening should begin and end. Cervical cancer is rare among women younger than 20 years. Screening for cervical cancer in this age group is complicated by lower rates of detection and higher rates of false-positive results than in older women. Methods used to diagnose and treat cervical intraepithelial neoplasia have important potential adverse effects. High-risk human papillomavirus infections and abnormalities on cytologic and histologic examination have relatively high rates of regression. Accordingly, cervical cancer screening in women younger than 20 years may be harmful. The incidence of, and mortality rates from, cervical cancer and the proportion of U.S. women aged 65 years or older who have had a Papanicolaou smear within 3 years have decreased since 2000. Available evidence supports discontinuation of cervical cancer screening among women aged 65 years or older who have had adequate screening and are not otherwise at high risk. Further reductions in the burden of cervical cancer in older women are probably best achieved by focusing on screening those who have not been adequately screened.
Overview: Risky behaviors are a leading cause of preventable morbidity and mortality, yet behavioral counseling interventions to address them are underutilized in healthcare settings. Research on ...such interventions has grown steadily, but the systematic review of this research is complicated by wide variations in the organization, content, and delivery of behavioral interventions and the lack of a consistent language and framework to describe these differences. The Counseling and Behavioral Interventions Work Group of the United States Preventive Services Task Force (USPSTF) was convened to address adapting existing USPSTF methods to issues and challenges raised by behavioral counseling intervention topical reviews.
The systematic review of behavioral counseling interventions seeks to establish whether such interventions addressing individual behaviors improve health outcomes. Few studies directly address this question, so evidence addressing whether changing individual behavior improves health outcomes and whether behavioral counseling interventions in clinical settings help people change those behaviors must be linked. To illustrate this process, we present two separate analytic frameworks derived from screening topic tools that we developed to guide USPSTF behavioral topic reviews.
No simple empirically validated model captures the broad range of intervention components across risk behaviors, but the Five A’s construct—assess, advise, agree, assist, and arrange—adapted from tobacco cessation interventions in clinical care provides a workable framework to report behavioral counseling intervention review findings. We illustrate the use of this framework with general findings from recent behavioral counseling intervention studies. Readers are referred to the USPSTF (www.ahrq.gov/clinic/prevenix.htm or 1-800-358-9295) for systematic evidence reviews and USPSTF recommendations based on these reviews for specific behaviors.
The mission of the Patient‐Centered Outcomes Research Institute (PCORI) is to fund the production of high‐quality evidence that will enable patients and clinicians to make informed, personalized ...healthcare decisions. Since 2012, the PCORI has invested $177 million in patient‐centered comparative effectiveness research (CER) that specifically targets the health needs of older adults, with additional relevant studies in its broader portfolio. Developing the PCORI's research portfolio has provided us with significant insights into what factors to consider when conducting CER in older adult populations. When comparing the net benefit of two or more interventions for older adults, investigators should consider the following: absolute risk difference, competing risks, life expectancy, the difference between chronologic and physiologic age, the importance of patient preferences, and other potential drivers of variable treatment effects. Investigators should also engage older adults and their caregivers as partners throughout the research process. Their input helps to identify key outcomes of interest and insights about the conduct of the research. As the PCORI continues to support research that addresses the healthcare decisions of the rapidly growing older adult population, it needs to partner with patients and researchers to identify the most important questions to address.

An important barrier to the delivery of health behavior change interventions in primary care settings is the lack of an integrated screening and intervention approach that can cut across multiple ...risk factors and help clinicians and patients to address these risks in an efficient and productive manner.
We review the evidence for interventions that separately address lack of physical activity, an unhealthy diet, obesity, cigarette smoking, and risky/harmful alcohol use, and evidence for interventions that address multiple behavioral risks drawn primarily from the cardiovascular and diabetes literature.
There is evidence for the efficacy of interventions to reduce smoking and risky/harmful alcohol use in unselected patients, and evidence for the efficacy of medium- to high-intensity dietary counseling by specially trained clinicians in high-risk patients. There is fair to good evidence for moderate, sustained weight loss in obese patients receiving high-intensity counseling, but insufficient evidence regarding weight loss interventions in nonobese adults. Evidence for the efficacy of physical activity interventions is limited. Large gaps remain in our knowledge about the efficacy of interventions to address multiple behavioral risk factors in primary care.
We derive several principles and strategies for delivering behavioral risk factor interventions in primary care from the research literature. These principles can be linked to the “5A's” construct (assess, advise, agree, assist, and arrange-follow up) to provide a unifying conceptual framework for describing, delivering, and evaluating health behavioral counseling interventions in primary healthcare settings. We also provide recommendations for future research.
