RESUMO
BACKGROUND: Primary care patients and clinicians may prefer options other than second-generation antidepressants for the treatment of major depressive disorder (MDD). The comparative benefits and harms of antidepressants and alternative treatments are unclear. PURPOSE: To compare the benefits and harms of second-generation antidepressants and psychological, complementary and alternative medicine (CAM), and exercise treatments as first- and second-step interventions for adults with acute MDD. DATA SOURCES: English-, German-, and Italian-language studies from multiple electronic databases (January 1990 to September 2015); trial registries and gray-literature databases were used to identify unpublished research. STUDY SELECTION: Two investigators independently selected comparative randomized trials of at least 6 weeks' duration on health outcomes of adult outpatients; nonrandomized studies were eligible for harms. DATA EXTRACTION: Reviewers abstracted data on study design, participants, interventions, and outcomes; rated the risk of bias; and graded the strength of evidence. A senior reviewer confirmed data and ratings. DATA SYNTHESIS: 45 trials met inclusion criteria. On the basis of moderate-strength evidence, cognitive behavioral therapy (CBT) and antidepressants led to similar response rates (relative risk [RR], 0.90 [95% CI, 0.76 to 1.07]) and remission rates (RR, 0.98 [CI, 0.73 to 1.32]). In trials, antidepressants had higher risks for adverse events than most other treatment options; no information from nonrandomized studies was available. The evidence was too limited to make firm conclusions about differences in the benefits and harms of antidepressants compared with other treatment options as first-step therapies for acute MDD. For second-step therapies, different switching and augmentation strategies provided similar symptom relief. LIMITATION: High dropout rates, dosing inequalities, small sample sizes, and poor assessment of adverse events limit confidence in the evidence. CONCLUSION: Given their similar efficacy, CBT and antidepressants are both viable choices for initial treatment of MDD. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

Importance: Many adverse health outcomes are associated with obstructive sleep apnea (OSA). Objective: To review primary care-relevant evidence on screening adults for OSA, test accuracy, and treatment of OSA, to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Library, EMBASE, and trial registries through October 2015, references, and experts, with surveillance of the literature through October 5, 2016. Study Selection: English-language randomized clinical trials (RCTs); studies evaluating accuracy of screening questionnaires or prediction tools, diagnostic accuracy of portable monitors, or association between apnea-hypopnea index (AHI) and health outcomes among community-based participants. Data Extraction and Synthesis: Two investigators independently reviewed abstracts and full-text articles. When multiple similar studies were available, random-effects meta-analyses were conducted. Main Outcomes and Measures: Sensitivity, specificity, area under the curve (AUC), AHI, Epworth Sleepiness Scale (ESS) scores, blood pressure, mortality, cardiovascular events, motor vehicle crashes, quality of life, and harms. Results: A total of 110 studies were included (N = 46â¯188). No RCTs compared screening with no screening. In 2 studies (n = 702), the screening accuracy of the multivariable apnea prediction score followed by home portable monitor testing for detecting severe OSA syndrome (AHI ≥30 and ESS score >10) was AUC 0.80 (95% CI, 0.78 to 0.82) and 0.83 (95% CI, 0.77 to 0.90), respectively, but the studies oversampled high-risk participants and those with OSA and OSA syndrome. No studies prospectively evaluated screening tools to report calibration or clinical utility for improving health outcomes. Meta-analysis found that continuous positive airway pressure (CPAP) compared with sham was significantly associated with reduction of AHI (weighted mean difference [WMD], -33.8 [95% CI, -42.0 to -25.6]; 13 trials, 543 participants), excessive sleepiness assessed by ESS score (WMD, -2.0 [95% CI, -2.6 to -1.4]; 22 trials, 2721 participants), diurnal systolic blood pressure (WMD, -2.4 points [95% CI, -3.9 to -0.9]; 15 trials, 1190 participants), and diurnal diastolic blood pressure (WMD, -1.3 points [95% CI, -2.2 to -0.4]; 15 trials, 1190 participants). CPAP was associated with modest improvement in sleep-related quality of life (Cohen d, 0.28 [95% CI, 0.14 to 0.42]; 13 trials, 2325 participants). Mandibular advancement devices (MADs) and weight loss programs were also associated with reduced AHI and excessive sleepiness. Common adverse effects of CPAP and MADs included oral or nasal dryness, irritation, and pain, among others. In cohort studies, there was a consistent association between AHI and all-cause mortality. Conclusions and Relevance: There is uncertainty about the accuracy or clinical utility of all potential screening tools. Multiple treatments for OSA reduce AHI, ESS scores, and blood pressure. Trials of CPAP and other treatments have not established whether treatment reduces mortality or improves most other health outcomes, except for modest improvement in sleep-related quality of life.

Importance: Preschool vision screening could allow detection and treatment of vision abnormalities during a critical developmental stage, preserving function and quality of life. Objective: To review the evidence on screening for and treatment of amblyopia, its risk factors, and refractive error in children aged 6 months to 5 years to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Library, CINAHL, and trial registries through June 2016; references; and experts, with surveillance of the literature through June 7, 2017. Study Selection: English-language randomized clinical trials (RCTs) or prospective cohort studies that evaluated screening, studies evaluating test accuracy, RCTs of treatment vs inactive controls, and cohort studies or case-control studies assessing harms. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, and study quality; qualitative synthesis of findings. Studies were not quantitatively pooled because of clinical and methodological heterogeneity. Main Outcomes and Measures: Visual acuity, amblyopia, school performance, functioning, quality of life, test accuracy, testability, and harms. Results: Forty studies were included (N = 34â¯709); 34 evaluated test accuracy. No RCTs compared screening with no screening, and no studies evaluated school performance, function, or quality of life. Studies directly assessing earlier or more intensive screening were limited by high attrition. Positive likelihood ratios were between 5 and 10 for amblyopia risk factors or nonamblyogenic refractive error in most studies of test accuracy and were greater than 10 in most studies evaluating combinations of clinical tests. Inability to cooperate may limit use of some tests in children younger than 3 years. Studies with low prevalence (<10%) of vision abnormalities showed high false-positive rates (usually >75%). Among children with amblyopia risk factors (eg, strabismus or anisometropia), patching improved visual acuity of the amblyopic eye by a mean of less than 1 line on a standard chart after 5 to 12 weeks for children pretreated with glasses (2 RCTs, 240 participants); more children treated with patching than with no patching experienced improvement of at least 2 lines (45% vs 21%; P = .003; 1 RCT, 180 participants). Patching plus glasses improved visual acuity by about 1 line after 1 year (0.11 logMAR [95% CI, 0.05-0.17]) for children not pretreated with glasses (1 RCT, 177 participants). Glasses alone improved visual acuity by less than 1 line after 1 year (0.08 logMAR [95% CI, 0.02-0.15], 1 RCT, 177 participants). Conclusions and Relevance: Studies directly evaluating the effectiveness of screening were limited and do not establish whether vision screening in preschool children is better than no screening. Indirect evidence supports the utility of multiple screening tests for identifying preschool children at higher risk for vision problems and the effectiveness of some treatments for improving visual acuity outcomes.

IMPORTANCE: Five to ten percent of individuals with latent tuberculosis infection (LTBI) progress to active tuberculosis (TB) disease. Identifying and treating LTBI is a key component of the strategy for reducing the burden of TB disease. OBJECTIVE: To review the evidence about targeted screening and treatment for LTBI among adults in primary care settings to support the US Preventive Services Task Force in updating its 1996 recommendation. DATA SOURCES: MEDLINE, Cochrane Library, and trial registries, searched through August 3, 2015; references from pertinent articles; and experts. Literature surveillance was conducted through May 31, 2016. STUDY SELECTION: English-language studies of LTBI screening, LTBI treatment with recommended pharmacotherapy, or accuracy of the tuberculin skin test (TST) or interferon-gamma release assays (IGRAs). Studies of individuals for whom LTBI screening and treatment is part of public health surveillance or disease management were excluded. DATA EXTRACTION AND SYNTHESIS: Two investigators independently reviewed abstracts and full-text articles. When at least 3 similar studies were available, random-effects meta-analysis was used to generate pooled estimates of outcomes. MAIN OUTCOMES AND MEASURES: Sensitivity, specificity, reliability, active TB disease, mortality, hepatotoxicity, and other harms. RESULTS: The review included 72 studies (n = 51â¯711). No studies evaluated benefits and harms of screening compared with no screening. Pooled estimates for sensitivity of the TST at both 5-mm and 10-mm induration thresholds were 0.79 (5-mm: 95% CI, 0.69-0.89 [8 studies, n = 803]; 10 mm: 95% CI, 0.71-0.87 [11 studies; n = 988]), and those for IGRAs ranged from 0.77 to 0.90 (57 studies; n = 4378). Pooled estimates for specificity of the TST at the 10-mm and 15-mm thresholds and for IGRAs ranged from 0.95 to 0.99 (34 studies; n = 23â¯853). A randomized clinical trial (RCT) of 24 weeks of isoniazid in individuals with pulmonary fibrotic lesions and LTBI (n = 27â¯830) found a reduction in absolute risk of active TB at 5 years from 1.4% to 0.5% (relative risk [RR], 0.35 [95% CI, 0.24-0.52]) and an increase in absolute risk for hepatoxicity from 0.1% to 0.5% (RR, 4.59 [95% CI, 2.03-10.39]) for 24 weeks of daily isoniazid compared with placebo. An RCT (n = 6886) found that 3 months of once-weekly rifapentine plus isoniazid was noninferior to 9 months of isoniazid alone for preventing active TB. The risk difference for hepatoxicity comparing isoniazid with rifampin ranged from 3% to 7%, with a pooled RR of 3.29 (95% CI, 1.72-6.28 [3 RCTs; n = 1327]). CONCLUSIONS AND RELEVANCE: No studies evaluated the benefits and harms of screening compared with no screening. Both the TST and IGRAs are moderately sensitive and highly specific within countries with low TB burden. Treatment reduced the risk of active TB among the populations included in this review. Isoniazid is associated with higher rates of hepatotoxicity than placebo or rifampin.

BACKGROUND: Approximately 10% of ischemic strokes are caused by carotid artery stenosis (CAS). Estimated prevalence of asymptomatic CAS is 1%. PURPOSE: To evaluate evidence on screening and treating asymptomatic adults for CAS. DATA SOURCES: MEDLINE, the Cochrane Library, EMBASE, and trial registries through September 2013; MEDLINE through March 2014 for trials. STUDY SELECTION: Good- or fair-quality trials of screening, carotid endarterectomy (CEA), or stenting compared with medical therapy or of intensification of medical therapy; systematic reviews; multi-institution studies reporting harms; and externally validated risk-stratification tools. DATA EXTRACTION: Dual extraction and quality assessment. DATA SYNTHESIS: No trials compared screening with no screening or stenting with medical therapy or assessed intensification of medical therapy, and no externally validated, reliable risk-stratification tools were found. Given the specificity of ultrasonography (range, 88% to 94% for CAS ≥ 50% to ≥ 70%), its use in low-prevalence populations would yield many false-positive results. Absolute reduction of nonperioperative strokes was 5.5% (95% CI, 3.9% to 7.0%; 3 trials; 5223 participants) over approximately 5 years for CEA compared with medical therapy. The 30-day rates of stroke or death after CEA in trials and cohort studies were 2.4% (CI, 1.7% to 3.1%; 6 trials; 3435 participants) and 3.3% (CI, 2.7% to 3.9%; 7 studies; 17474 participants), respectively. Other harms of interventions included myocardial infarction, nerve injury, and hematoma. LIMITATIONS: Trials may have overestimated benefits and used highly selected surgeons. Medical therapy used in trials was outdated, and stroke rates have declined in recent decades. Harms may have been underreported. CONCLUSION: Current evidence does not establish incremental overall benefit of CEA, stenting, or intensification of medical therapy. Potential for overall benefit is limited by low prevalence and harms. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

IMPORTANCE: Alcohol use disorders cause substantial morbidity and early mortality yet remain greatly undertreated. Medications are considerably underused. OBJECTIVE: To conduct a systematic review and meta-analysis of the benefits and harms of medications (US FDA-approved and others) for adults with alcohol use disorders. DATA SOURCES: PubMed, Cochrane Library, PsycINFO, CINAHL, EMBASE, FDA website, and clinical trials registries (January 1, 1970, to March 1, 2014). STUDY SELECTION: Two reviewers selected randomized clinical trials (RCTs) with at least 12 weeks' duration that reported eligible outcomes and head-to-head prospective cohort studies reporting health outcomes or harms. DATA EXTRACTION AND SYNTHESIS: We conducted meta-analyses using random-effects models and calculated numbers needed to treat for benefit (NNTs) or harm (NNHs). MAIN OUTCOMES AND MEASURES: Alcohol consumption, motor vehicle crashes, injuries, quality of life, function, mortality, and harms. RESULTS: We included 122 RCTs and 1 cohort study (total 22,803 participants). Most assessed acamprosate (27 studies, n = 7519), naltrexone (53 studies, n = 9140), or both. The NNT to prevent return to any drinking for acamprosate was 12 (95% CI, 8 to 26; risk difference [RD], -0.09; 95% CI, -0.14 to -0.04) and was 20 (95% CI, 11 to 500; RD, -0.05; 95% CI, -0.10 to -0.002) for oral naltrexone (50 mg/d). The NNT to prevent return to heavy drinking was 12 (95% CI, 8 to 26; RD -0.09; 95% CI, -0.13 to -0.04) for oral naltrexone (50 mg/d). Meta-analyses of trials comparing acamprosate to naltrexone found no statistically significant difference between them for return to any drinking (RD, 0.02; 95% CI, -0.03 to 0.08) or heavy drinking (RD, 0.01; 95% CI, -0.05 to 0.06). For injectable naltrexone, meta-analyses found no association with return to any drinking (RD, -0.04; 95% CI, -0.10 to 0.03) or heavy drinking (RD, -0.01; 95% CI, -0.14 to 0.13) but found an association with reduction in heavy drinking days (weighted mean difference [WMD], -4.6%; 95% CI, -8.5% to -0.56%). Among medications used off-label, moderate evidence supports an association with improvement in some consumption outcomes for nalmefene (heavy drinking days per month: WMD, -2.0; 95% CI, -3.0 to -1.0; drinks per drinking day: WMD, -1.02; 95% CI, -1.77 to -0.28) and topiramate (% heavy drinking days: WMD, -9.0%; 95% CI, -15.3% to -2.7%; drinks per drinking day: WMD, -1.0; 95% CI, -1.6 to -0.48). For naltrexone and nalmefene, NNHs for withdrawal from trials due to adverse events were 48 (95% CI, 30 to 112) and 12 (95% CI, 7 to 50), respectively; risk was not significantly increased for acamprosate or topiramate. CONCLUSIONS AND RELEVANCE: Both acamprosate and oral naltrexone were associated with reduction in return to drinking. When directly compared with one another, no significant differences were found between acamprosate and naltrexone for controlling alcohol consumption. Factors such as dosing frequency, potential adverse events, and availability of treatments may guide medication choice.

BACKGROUND: Alcohol misuse, which includes the full spectrum from risky drinking to alcohol dependence, is a leading cause of preventable death in the United States. PURPOSE: To evaluate the benefits and harms of behavioral counseling interventions for adolescents and adults who misuse alcohol. DATA SOURCES: MEDLINE, EMBASE, the Cochrane Library, CINAHL, PsycINFO, International Pharmaceutical Abstracts, and reference lists of published literature (January 1985 through January 2012, limited to English-language articles). STUDY SELECTION: Controlled trials at least 6 months' duration that enrolled persons with alcohol misuse identified by screening in primary care settings and evaluated behavioral counseling interventions. DATA EXTRACTION: One reviewer extracted data and a second checked accuracy. Two independent reviewers assigned quality ratings and graded the strength of the evidence. DATA SYNTHESIS: The 23 included trials generally excluded persons with alcohol dependence. The best evidence was for brief (10- to 15-minute) multicontact interventions. Among adults receiving behavioral interventions, consumption decreased by 3.6 drinks per week from baseline (weighted mean difference, 3.6 drinks/wk [95% CI, 2.4 to 4.8 drinks/wk]; 10 trials; 4332 participants), 12% fewer adults reported heavy drinking episodes (risk difference, 0.12 [CI, 0.07 to 0.16]; 7 trials; 2737 participants), and 11% more adults reported drinking less than the recommended limits (risk difference, 0.11 [CI, 0.08 to 0.13]; 9 trials; 5973 participants) over 12 months compared with control participants (moderate strength of evidence). Evidence was insufficient to draw conclusions about accidents, injuries, or alcohol-related liver problems. Trials enrolling young adults or college students showed reduced consumption and fewer heavy drinking episodes (moderate strength of evidence). Little or no evidence of harms was found. LIMITATIONS: Results may be biased to the null because the behavior of control participants could have been affected by alcohol misuse assessments. In addition, evidence is probably inapplicable to persons with alcohol dependence and selective reporting may have occurred. CONCLUSION: Behavioral counseling interventions improve behavioral outcomes for adults with risky drinking. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

Opioid use disorder (OUD) and its consequences are a major public health concern. The partial agonist buprenorphine is a safe and effective treatment for OUD, but concerns about abuse, misuse, and diversion of buprenorphine have been raised. This narrative review examined the rates and motives for use of illicit buprenorphine in the United States. Findings from the 17 included studies suggest the majority of study participants using illicit buprenorphine do so for reasons related to misuse (to manage opioid withdrawal symptoms or achieve or maintain abstinence from other opioids). A smaller percentage of study respondents reported using buprenorphine for reasons related to abuse (to get high). There appears to be a gap between need for buprenorphine and access to adequate treatment. Attenuation of policy-related barriers and adoption of appropriate buprenorphine use by the treatment community are critical tools in the continued effort to reduce the burdens associated with OUD.

OBJECTIVES: To report the comparative benefits and harms of exercise and complementary and alternative medicine (CAM) treatments with second-generation antidepressants (SGA) for major depressive disorder (MDD). DESIGN: Systematic review and meta-analysis. SETTINGS: Outpatient clinics. SUBJECTS: Adults, aged 18 years and older, with MDD receiving an initial treatment attempt with SGA. INTERVENTIONS: Any CAM or exercise intervention compared with an SGA. OUTCOME MEASURES: Treatment response, remission, change in depression rating, adverse events, treatment discontinuation, and treatment discontinuation due to adverse events. RESULTS: We found 22 randomized controlled trials for direct comparisons and 127 trials for network meta-analyses, including trials of acupuncture, omega-3 fatty acids, S-adenosyl methionine, St. John's wort, and exercise. For most treatment comparisons, we found no differences between treatment groups for response and remission. However, the risk of bias of these studies led us to conclude that the strength of evidence for these findings was either low or insufficient. The risk of treatment harms and treatment discontinuation attributed to adverse events was higher for selective serotonin receptor inhibitors than for St. John's wort. CONCLUSIONS: Although we found little difference in the comparative efficacy of most CAM therapies or exercise and SGAs, the overall poor quality of the available evidence base tempers any conclusions that we might draw from those trials. Future trials should incorporate patient-oriented outcomes, treatment expectancy, depressive severity, and harms assessments into their designs; antidepressants should be administered over their full dosage ranges; and larger trials using methods to reduce sampling bias are needed.

BACKGROUND: Individualized decision making has been recommended for cancer screening decisions in older adults. Because older adults' preferences are central to individualized decisions, we assessed older adults' perspectives about continuing cancer screening later in life. METHODS: Face to face interviews with 116 residents age 70 or over from two long-term care retirement communities. Interview content included questions about whether participants had discussed cancer screening with their physicians since turning age 70, their attitudes about information important for individualized decisions, and their attitudes about continuing cancer screening later in life. RESULTS: Forty-nine percent of participants reported that they had an opportunity to discuss cancer screening with their physician since turning age 70; 89% would have preferred to have had these discussions. Sixty-two percent believed their own life expectancy was not important for decision making, and 48% preferred not to discuss life expectancy. Attitudes about continuing cancer screening were favorable. Most participants reported that they would continue screening throughout their lives and 43% would consider getting screened even if their doctors recommended against it. Only 13% thought that they would not live long enough to benefit from cancer screening tests. Factors important to consider stopping include: age, deteriorating or poor health, concerns about the effectiveness of the tests, and doctors recommendations. CONCLUSION: This select group of older adults held positive attitudes about continuing cancer screening later in life, and many may have had unrealistic expectations. Individualized decision making could help clarify how life expectancy affects the potential survival benefits of cancer screening. Future research is needed to determine whether educating older adults about the importance of longevity in screening decisions would be acceptable, affect older adults' attitudes about screening, or change their screening behavior.

BACKGROUND: Estimates of life expectancy assist physicians and patients in medical decision-making. The time-delayed benefits for many medical treatments make an older adult's life expectancy estimate particularly important for physicians. The purpose of this study is to assess older adults' beliefs about physician-estimated life expectancy. METHODS: We performed a mixed qualitative-quantitative cross-sectional study in which 116 healthy adults aged 70+ were recruited from two local retirement communities. We interviewed them regarding their beliefs about physician-estimated life expectancy in the context of a larger study on cancer screening beliefs. Semi-structured interviews of 80 minutes average duration were performed in private locations convenient to participants. Demographic characteristics as well as cancer screening beliefs and beliefs about life expectancy were measured. Two independent researchers reviewed the open-ended responses and recorded the most common themes. The research team resolved disagreements by consensus. RESULTS: This article reports the life-expectancy results portion of the larger study. The study group (n = 116) was comprised of healthy, well-educated older adults, with almost a third over 85 years old, and none meeting criteria for dementia. Sixty-four percent (n = 73) felt that their physicians could not correctly estimate their life expectancy. Sixty-six percent (n = 75) wanted their physicians to talk with them about their life expectancy. The themes that emerged from our study indicate that discussions of life expectancy could help older adults plan for the future, maintain open communication with their physicians, and provide them knowledge about their medical conditions. CONCLUSION: The majority of the healthy older adults in this study were open to discussions about life expectancy in the context of discussing cancer screening tests, despite awareness that their physicians' estimates could be inaccurate. Since about a third of participants perceived these discussions as not useful or even harmful, physicians should first ascertain patients' preferences before discussing their life expectancies.

AIMS: To assess the safety of buprenorphine compared with methadone to treat pregnant women with opioid use disorder. METHODS: We searched PubMed, Embase and the Cochrane Library from inception to February 2015 for randomized controlled trials (RCT) and observational cohort studies (OBS) that compared buprenorphine with methadone for treating opioid-dependent pregnant women. Two reviewers assessed independently the titles and abstracts of all search results and full texts of potentially eligible studies reporting original data for maternal/fetal/infant death, preterm birth, fetal growth outcomes, fetal/congenital anomalies, fetal/child neurodevelopment and/or maternal adverse events. We ascertained each study's risk of bias using validated instruments and assessed the strength of evidence for each outcome using established methods. We computed effect sizes using random-effects models for each outcome with two or more studies. RESULTS: Three RCTs (n = 223) and 15 cohort OBSs (n = 1923) met inclusion criteria. In meta-analyses using unadjusted data and methadone as comparator, buprenorphine was associated with lower risk of preterm birth [RCT risk ratio (RR) = 0.40, 95% confidence interval (CI) = 0.18, 0.91; OBS RR = 0.67, 95% CI = 0.50, 0.90], greater birth weight [RCT weighted mean difference (WMD) = 277 g, 95% CI = 104, 450; OBS WMD = 265 g, 95% CI = 196, 335] and larger head circumference [RCT WMD = 0.90 cm, 95% CI = 0.14, 1.66; OBS WMD = 0.68 cm, 95% CI = 0.41, 0.94]. No treatment differences were observed for spontaneous fetal death, fetal/congenital anomalies and other fetal growth measures, although the power to detect such differences may be inadequate due to small sample sizes. CONCLUSIONS: Moderately strong evidence indicates lower risk of preterm birth, greater birth weight and larger head circumference with buprenorphine treatment of maternal opioid use disorder during pregnancy compared with methadone treatment, and no greater harms.

STUDY QUESTION: What are the benefits and harms of second generation antidepressants and cognitive behavioral therapies (CBTs) in the initial treatment of a current episode of major depressive disorder in adults? METHODS: This was a systematic review including qualitative assessment and meta-analyses using random and fixed effects models. Medline, Embase, the Cochrane Library, the Allied and Complementary Medicine Database, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature were searched from January 1990 through January 2015. The 11 randomized controlled trials included compared a second generation antidepressant CBT. Ten trials compared antidepressant monotherapy with CBT alone; three compared antidepressant monotherapy with antidepressant plus CBT. SUMMARY ANSWER AND LIMITATIONS: Meta-analyses found no statistically significant difference in effectiveness between second generation antidepressants and CBT for response (risk ratio 0.91, 0.77 to 1.07), remission (0.98, 0.73 to 1.32), or change in 17 item Hamilton Rating Scale for Depression score (weighted mean difference, -0.38, -2.87 to 2.10). Similarly, no significant differences were found in rates of overall study discontinuation (risk ratio 0.90, 0.49 to 1.65) or discontinuation attributable to lack of efficacy (0.40, 0.05 to 2.91). Although more patients treated with a second generation antidepressant than receiving CBT withdrew from studies because of adverse events, the difference was not statistically significant (risk ratio 3.29, 0.42 to 25.72). No conclusions could be drawn about other outcomes because of lack of evidence. Results should be interpreted cautiously given the low strength of evidence for most outcomes. The scope of this review was limited to trials that enrolled adult patients with major depressive disorder and compared a second generation antidepressant with CBT, and many of the included trials had methodological shortcomings that may limit confidence in some of the findings. WHAT THIS STUDY ADDS: Second generation antidepressants and CBT have evidence bases of benefits and harms in major depressive disorder. Available evidence suggests no difference in treatment effects of second generation antidepressants and CBT, either alone or in combination, although small numbers may preclude detection of small but clinically meaningful differences.

AIM: To assess whether response to medications for alcohol use disorders varies by genotype. METHODS: Systematic review and meta-analysis. RESULTS: We found no studies that assessed the clinical utility of genotype-guided dosing strategies or genotype-guided medication selection, and none randomized by genotype. All included studies assessed the association between genotype and response to medication. Of 15 included studies, eight (n = 1365 participants) assessed variation in naltrexone response and polymorphisms of OPRM1. Our meta-analyses for return to heavy drinking found no significant difference between A allele homozygotes and those with at least one G allele, both without (risk difference: 0.26; 95% CI: -0.01-0.53; n = 174) and with inclusion of studies rated as high or unclear risk of bias (risk difference: 0.14; 95% CI: -0.03-0.3; n = 382). For all other polymorphism-medication pairs, we found just one eligible study. CONCLUSION: Estimates of effect for return to heavy drinking suggest it is possible that patients with at least one G allele of A118G polymorphism of OPRM1 might be more likely to respond to naltrexone, but confidence intervals were wide; additional studies are needed to improve confidence in the estimates.

BACKGROUND: Depression concomitant with chronic medical conditions is common and burdensome in primary care. OBJECTIVE: To assess the effectiveness of practice-based interventions for improving depression and chronic medical outcomes. DATA SOURCES: MEDLINE, Embase, the Cochrane Library, CINAHL, and PsycINFO from inception to June 11, 2012. STUDY SELECTION, APPRAISAL, AND SYNTHESIS: Two reviewers independently selected, extracted data from, and rated the quality of trials and systematic reviews. Strength of evidence (SOE) was graded using established criteria. RESULTS: Twenty-four published articles reported data from 12 studies, all at least 6 months long. All studies compared a form of collaborative care with usual or enhanced usual care. Studies evaluated adults with arthritis, cancer, diabetes, heart disease, HIV, or multiple medical conditions. Meta-analyses found that intervention recipients achieved greater improvement than controls in depression symptoms, response, remission, and depression-free days (moderate SOE); satisfaction with care (moderate SOE); and quality of life (moderate SOE). Few data were available on outcomes for chronic medical conditions. Meta-analyses revealed that patients with diabetes receiving collaborative care exhibited no difference in diabetes control compared with control groups (change in HbA1c: weighted mean difference 0.13, 95% confidence interval = -0.22 to 0.48 at 6 months; 0.24, 95% confidence interval = -0.14 to 0.62 at 12 months; low SOE). The only study to use HbA1c as a predefined outcome measure and a "treat-to-target" intervention for diabetes as well as depression, TEAMcare, reported significant reductions in HbA1c (7.42 vs 7.87 at 6 months; 7.33 vs 7.81 at 12 months; overall P < .001). LIMITATIONS: Few relevant trials reported on medical outcomes. CONCLUSIONS: Collaborative care interventions improved outcomes for depression and quality of life in primary care patients with varying medical conditions. Few data were available on medical outcomes. Future studies of concomitant depression and chronic medical conditions should consider measures of medical outcomes as primary outcomes.

Over the past 10 years, the field of health services and management research has seen renewed interest in the use of qualitative research methods. This article examines the volume and characteristics of qualitative research articles published in nine major health services and management journals between 1998 and 2008. Qualitative research articles comprise 9% of research articles published in these journals. Although the publication rate of qualitative research articles has not kept pace with that of quantitative research articles, citation analysis suggests that qualitative research articles contribute comparably to the field's knowledge base. A wide range of policy and management topics has been examined using qualitative methods. Case study designs, interviews, and documentary sources were the most frequently used methods. Half of qualitative research articles provided little or no detail about key aspects the study's methods. Implications are discussed and recommendations are offered for promoting the publication of qualitative research.

OBJECTIVE: Despite a growing understanding of late-life depression, few studies focus on the old-old, those 75 years and over. We wished to characterize depressive symptoms and determine the accuracy of two common screening instruments for major and minor depression in a population of old-old retirees. METHODS: Participants lived independently in one of two Continuing Care Retirement Communities and volunteered for an in-home interview about cancer screening attitudes. As part of this baseline interview, they were screened with the Geriatric Depression Scale (GDS) and the Center for Epidemiologic Studies-Depression (CES-D) scale. Those agreeing to a second interview received an evaluation using the Structured Clinical Interview for DSM-IV (SCID-IV), performed by a geriatric psychiatrist within two weeks of the initial interview. RESULTS: In an educated and cognitively intact group of retirees averaging 80 years of age, the GDS and CES-D performed poorly using standard cutpoints in detecting both major (sensitivity 60% for both) and minor (sensitivity 33% and 50%, respectively) depression. One in five participants had significant depression as confirmed by SCID-IV evaluation. Twelve percent had major depression and 7% had minor depression. Most participants had their first episode of either after age 60. CONCLUSIONS: Contrary to most studies evaluating the GDS and CES-D for accuracy in detecting late-life depression, these instruments at standard cutpoints performed poorly in this group of healthy older adults. The healthy old-old may require novel screening interventions to detect clinically significant depression.
