RESUMEN

OBJECTIVE: To (1) investigate the extent to which recently published meta-analyses report trial funding, author-industry financial ties and author-industry employment from included randomised controlled trials (RCTs), comparing Cochrane and non-Cochrane meta-analyses; (2) examine characteristics of meta-analyses independently associated with reporting funding sources of included RCTs; and (3) compare reporting among recently published Cochrane meta-analyses to Cochrane reviews published in 2010. DESIGN: Review of consecutive sample of recently published meta-analyses. DATA SOURCES: MEDLINE database via PubMed searched on 19 October 2018. ELIGIBILITY CRITERIA FOR SELECTING ARTICLES: We selected the 250 most recent meta-analyses listed in PubMed that included a documented search of at least one database, statistically combined results from ≥2 RCTs and evaluated the effects of a drug or class of drugs. RESULTS: 90 of 107 (84%) Cochrane meta-analyses reported funding sources for some or all included trials compared with 21 of 143 (15%) non-Cochrane meta-analyses, a difference of 69% (95% CI 59% to 77%). Percent reporting was also higher for Cochrane meta-analyses compared with non-Cochrane meta-analyses for trial author-industry financial ties (44% versus 1%; 95% CI for difference 33% to 52%) and employment (17% versus 1%; 95% CI for difference 9% to 24%). In multivariable analysis, compared with Cochrane meta-analyses, the odds ratio (OR) for reporting trial funding was ≤0.11 for all other journal category and impact factor combinations. Compared with Cochrane reviews from 2010, reporting of funding sources of included RCTs among recently published Cochrane meta-analyses improved by 54% (95% CI 42% to 63%), and reporting of trial author-industry financial ties and employment improved by 37% (95% CI 26% to 47%) and 10% (95% CI 2% to 19%). CONCLUSIONS: Reporting of trial funding sources, trial author-industry financial ties and trial author-industry employment in Cochrane meta-analyses has improved since 2010 and is higher than in non-Cochrane meta-analyses.

RESUMEN

BACKGROUND: A previous study found that 2 of 29 (6.9%) meta-analyses published in high-impact journals in 2009 reported included drug trials' funding sources, and none reported trial authors' financial conflicts of interest (FCOIs) or industry employment. It is not known if reporting has improved since 2009. Our objectives were to (1) investigate the extent to which pharmaceutical industry funding and author-industry FCOIs and employment from included drug trials are reported in meta-analyses published in high-impact journals and (2) compare current reporting with results from 2009. METHODS: We searched PubMed (January 2017-October 2018) for systematic reviews with meta-analyses including ≥ 2 randomized controlled trials (RCTs) of patented drugs. We included 3 meta-analyses published January 2017-October 2018 from each of 4 high-impact general medicine journals, high-impact journals from 5 specialty areas, and the Cochrane Database of Systematic Reviews, as in the previous study. RESULTS: Among 29 meta-analyses reviewed, 13 of 29 (44.8%) reported the funding source of included trials compared to 2 of 29 (6.9%) in 2009, a difference of 37.9% (95% confidence interval, 15.7 to 56.3%); this included 7 of 11 (63.6%) from general medicine journals, 3 of 15 (20.0%) from specialty medicine journals, and 3 of 3 (100%) Cochrane reviews. Only 2 of 29 meta-analyses (6.9%) reported trial author FCOIs, and none reported trial author-industry employment. PROTOCOL PUBLICATION: A protocol was uploaded to the Open Science Framework prior to initiating the study. https://osf.io/8xt5p/ LIMITATIONS: We examined only a relatively small number of meta-analyses from selected high-impact journals and compared results to a similarly small sample from an earlier time period. CONCLUSIONS: Reporting of drug trial sponsorship and author FCOIs in meta-analyses published in high-impact journals has increased since 2009 but is still suboptimal. Standards on reporting of trial funding described in the forthcoming revised PRISMA statement should be adapted and enforced by journals to improve reporting.

RESUMEN

OBJECTIVE: Depression screening among children and adolescents is controversial. In 2009, the United States Preventive Services Task Force first recommended routine depression screening for adolescents, and this recommendation was reiterated in 2016. However, no randomized controlled trials (RCTs) of screening were identified in the original 2009 systematic review or in an updated review through February 2015. The objective of this systematic review was to provide a current evaluation to determine whether there is evidence from RCTs that depression screening in childhood and adolescence improves depression outcomes. METHOD: Data sources included the MEDLINE, MEDLINE In-Process, EMBASE, PsycINFO, Cochrane CENTRAL and LILACS databases searched February 2, 2017. Eligible studies had to be RCTs that compared depression outcomes between children or adolescents aged 6 to 18 years who underwent depression screening and those who did not. RESULTS: Of 552 unique title/abstracts, none received full-text review. No RCTs that investigated the effects of screening on depression outcomes in children or adolescents were identified. CONCLUSIONS: There is no direct RCT evidence that supports depression screening among children and adolescents. Groups that consider recommending screening should carefully consider potential harms, as well as the use of scarce health resources, that would occur with the implementation of screening programs.

RESUMEN

OBJECTIVE: Depression screening among children and adolescents is controversial, and no clinical trials have evaluated benefits and harms of screening programs. A requirement for effective screening is a screening tool with demonstrated high accuracy. The objective of this systematic review was to evaluate the accuracy of depression screening instruments to detect major depressive disorder (MDD) in children and adolescents. METHOD: Data sources included the MEDLINE, MEDLINE In-Process, EMBASE, PsycINFO, HaPI, and LILACS databases from 2006 to September 30, 2015. Eligible studies compared a depression screening tool to a validated diagnostic interview for MDD and reported accuracy data for children and adolescents aged 6 to 18 years. Risk of bias was assessed with QUADAS-2. RESULTS: We identified 17 studies with data on 20 depression screening tools. Few studies examined the accuracy of the same screening tools. Cut-off scores identified as optimal were inconsistent across studies. Width of 95% confidence intervals (CIs) for sensitivity ranged from 9% to 55% (median 32%), and only 1 study had a lower bound 95% CI ≥80%. For specificity, 95% CI width ranged from 2% to 27% (median 9%), and 3 studies had a lower bound ≥90%. Methodological limitations included small sample sizes, exploratory data analyses to identify optimal cut-offs, and the failure to exclude children and adolescents already diagnosed or treated for depression. CONCLUSIONS: There is insufficient evidence that any depression screening tool and cut-off accurately screens for MDD in children and adolescents. Screening could lead to overdiagnosis and the consumption of scarce health care resources.

RESUMEN

OBJECTIVE: Clinical practice guidelines disagree on whether health care professionals should screen women for depression during pregnancy or postpartum. The objective of this systematic review was to determine whether depression screening improves depression outcomes among women during pregnancy or the postpartum period. METHODS: Searches included the CINAHL, EMBASE, ISI, MEDLINE, and PsycINFO databases through April 1, 2013; manual journal searches; reference list reviews; citation tracking of included articles; and trial registry reviews. RCTs in any language that compared depression outcomes between women during pregnancy or postpartum randomized to undergo depression screening versus women not screened were eligible. RESULTS: There were 9,242 unique titles/abstracts and 15 full-text articles reviewed. Only 1 RCT of screening postpartum was included, but none during pregnancy. The eligible postpartum study evaluated screening in mothers in Hong Kong with 2-month-old babies (N=462) and reported a standardized mean difference for symptoms of depression at 6 months postpartum of 0.34 (95% confidence interval=0.15 to 0.52, P<0.001). Standardized mean difference per 44 additional women treated in the intervention trial arm compared to the non-screening arm was approximately 1.8. Risk of bias was high, however, because the status of outcome measures was changed post-hoc and because the reported effect size per woman treated was 6-7 times the effect sizes reported in comparable depression care interventions. CONCLUSION: There is currently no evidence from any well-designed and conducted RCT that screening for depression would benefit women in pregnancy or postpartum. Existing guidelines that recommend depression screening during pregnancy or postpartum should be re-considered.

RESUMEN

BACKGROUND: The United States Preventive Services Task Force (USPSTF) recommends screening adults for depression in primary care settings when staff-assisted depression management programs are available. This recommendation, however, is based on evidence from depression management programs conducted with patients already identified as depressed, even though screening is intended to identify depressed patients not already recognized or treated. The objective of this systematic review was to evaluate whether there is evidence from randomized controlled trials (RCTs) that depression screening benefits patients in primary care, using an explicit definition of screening. METHODS: We re-evaluated RCTs included in the 2009 USPSTF evidence review on depression screening, including only trials that compared depression outcomes between screened and non-screened patients and met the following three criteria: determined patient eligibility and randomized prior to screening; excluded patients already diagnosed with a recent episode of depression or already being treated for depression; and provided the same level of depression treatment services to patients identified as depressed in the screening and non-screening trial arms. We also reviewed studies included in a recent Cochrane systematic review, but not the USPSTF review; conducted a focused search to update the USPSTF review; and reviewed trial registries. RESULTS: Of the nine RCTs included in the USPSTF review, four fulfilled none of three criteria for a test of depression screening, four fulfilled one of three criteria, and one fulfilled two of three criteria. There were two additional RCTs included only in the Cochrane review, and each fulfilled one of three criteria. No eligible RCTs were found via the updated review. CONCLUSIONS: The USPSTF recommendation to screen adults for depression in primary care settings when staff-assisted depression management programs are available is not supported by evidence from any RCTs that are directly relevant to the recommendation. The USPSTF should re-evaluate this recommendation. Please see related article: http://www.biomedcentral.com/1741-7015/12/14 REGISTRATION: PROSPERO (#CRD42013004276).

RESUMEN

OBJECTIVE: Several practice guidelines recommend routine screening for psychological distress in cancer care. The objective was to evaluate the effect of screening cancer patients for psychological distress by assessing the (1) effectiveness of interventions to reduce distress among patients identified as distressed; and (2) effects of screening for distress on distress outcomes. METHODS: CINAHL, Cochrane, EMBASE, ISI, MEDLINE, PsycINFO, and SCOPUS databases were searched through April 6, 2011 with manual searches of 45 relevant journals, reference list review, citation tracking of included articles, and trial registry reviews through June 30, 2012. Articles in any language on cancer patients were included if they (1) compared treatment for patients with psychological distress to placebo or usual care in a randomized controlled trial (RCT); or (2) assessed the effect of screening on psychological distress in a RCT. RESULTS: There were 14 eligible RCTs for treatment of distress, and 1 RCT on the effects of screening on patient distress. Pharmacological, psychotherapy and collaborative care interventions generally reduced distress with small to moderate effects. One study investigated effects of screening for distress on psychological outcomes, and it found no improvement. CONCLUSION: Treatment studies reported modest improvement in distress symptoms, but only a single eligible study was found on the effects of screening cancer patients for distress, and distress did not improve in screened patients versus those receiving usual care. Because of the lack of evidence of beneficial effects of screening cancer patients for distress, it is premature to recommend or mandate implementation of routine screening.

RESUMEN

OBJECTIVES: To systematically review evidence on depression screening in coronary heart disease (CHD) by assessing the (1) accuracy of screening tools; (2) effectiveness of treatment; and (3) effect of screening on depression outcomes. BACKGROUND: A 2008 American Heart Association (AHA) Science Advisory recommended routine depression screening in CHD. METHODS: CINAHL, Cochrane, EMBASE, ISI, MEDLINE, PsycINFO and SCOPUS databases searched through December 2, 2011; manual journal searches; reference lists; citation tracking; trial registries. Included articles (1) compared a depression screening instrument to a depression diagnosis; (2) compared depression treatment to placebo or usual care in a randomized controlled trial (RCT); or (3) assessed the effect of screening on depression outcomes in a RCT. RESULTS: There were few examples of screening tools with good sensitivity and specificity using a priori-defined cutoffs in more than one patient sample among 15 screening accuracy studies. Depression treatment with antidepressants or psychotherapy generated modest symptom reductions among post-myocardial infarction (post-MI) and stable CHD patients (N = 6; effect size = 0.20-0.38), but antidepressants did not improve symptoms more than placebo in 2 heart failure (HF) trials. Depression treatment did not improve cardiac outcomes. No RCTs investigated the effects of screening on depression outcomes. CONCLUSIONS: There is evidence that treatment of depression results in modest improvement in depressive symptoms in post-MI and stable CHD patients, although not in HF patients. There is still no evidence that routine screening for depression improves depression or cardiac outcomes. The AHA Science Advisory on depression screening should be revised to reflect this lack of evidence.

RESUMEN

BACKGROUND: Depression is an important cause of disability among children and adolescents. Depression screening is one possible method for managing depression, and screening programs have been initiated in some school and medical settings. However, in 2005, the Canadian Task Force on Preventive Health Care and the United Kingdom National Institute of Clinical Excellence did not recommend depression screening among children and adolescents. By contrast, in 2009, the United States Preventive Services Task Force recommended that all adolescents, but not younger children, be screened for depression in medical settings with integrated depression management services, although no trials of screening were identified. The objectives of this systematic review are to evaluate in children and adolescents the accuracy of depression screening tools; depression treatment efficacy; whether depression screening improves depression outcomes; and potential harms related to depression interventions and screening. METHODS/DESIGN: Data sources will include the bibliographic databases MEDLINE, Cochrane CENTRAL, PsycINFO, EMBASE, LILACS and Web of Science, supplemented by reference harvesting of eligible articles, relevant systematic reviews, relevant guidelines and recommendations, and selected journals, and by searches for unpublished studies. Eligible studies will report data for children and adolescents aged 6 to 18 years. Eligible diagnostic accuracy studies must compare a depression screening tool to a validated diagnostic interview for major depressive disorder and report diagnostic accuracy data. Eligible treatment studies must be randomized controlled trials of pharmacological, psychotherapeutic, or other depression treatments commonly available for children and adolescents in pediatric, primary-care, and family medicine settings. Eligible screening studies must be randomized controlled trials that compare depression outcomes between children or adolescents who underwent depression screening versus those who did not. Studies of harms will include randomized controlled trials and observational studies that evaluate harms from depression screening or treatment. Two investigators will independently review titles and abstracts, followed by full article review. Disagreements will be resolved by consensus. Two investigators will independently extract the data, with discrepancies resolved via consensus. DISCUSSION: The proposed systematic review will determine whether there is sufficient evidence of benefits in excess of harms and costs to support screening for depression in childhood and adolescence.

RESUMEN

OBJECTIVES: To investigate the degree to which Cochrane reviews of drug interventions published in 2010 reported conflicts of interest from included trials and, among reviews that reported this information, where it was located in the review documents. DESIGN: Cross sectional study. DATA SOURCES: Cochrane Database of Systematic Reviews. SELECTION CRITERIA: Systematic reviews of drug interventions published in 2010 in the Cochrane Database of Systematic Reviews, with review content classified as up to date in 2008 or later and with results from one or more randomised controlled trials. RESULTS: Of 151 included Cochrane reviews, 46 (30%, 95% confidence interval 24% to 38%) reported information on the funding sources of included trials, including 30 (20%, 14% to 27%) that reported information on trial funding for all included trials and 16 (11%, 7% to 17%) that reported for some, but not all, trials. Only 16 of the 151 Cochrane reviews (11%, 7% to 17%) provided any information on trial author-industry financial ties or trial author-industry employment. Information on trial funding and trial author-industry ties was reported in one to seven locations within each review, with no consistent reporting location observed. CONCLUSIONS: Most Cochrane reviews of drug trials published in 2010 did not provide information on trial funding sources or trial author-industry financial ties or employment. When this information was reported, location of reporting was inconsistent across reviews.

RESUMEN

BACKGROUND: Several practice guidelines recommend screening for depression in cancer care, but no systematic reviews have examined whether there is evidence that depression screening benefits cancer patients. The objective was to evaluate the potential benefits of depression screening in cancer patients by assessing the (1) accuracy of depression screening tools; (2) effectiveness of depression treatment; and (3) effect of depression screening, either alone or in the context of comprehensive depression care, on depression outcomes. METHODS: Data sources were CINAHL, Cochrane, EMBASE, ISI, MEDLINE, PsycINFO and SCOPUS databases through January 24, 2011; manual journal searches; reference lists; citation tracking; trial registry reviews. Articles on cancer patients were included if they (1) compared a depression screening instrument to a valid criterion for major depressive disorder (MDD); (2) compared depression treatment with placebo or usual care in a randomized controlled trial (RCT); (3) assessed the effect of screening on depression outcomes in a RCT. RESULTS: There were 19 studies of screening accuracy, 1 MDD treatment RCT, but no RCTs that investigated effects of screening on depression outcomes. Screening accuracy studies generally had small sample sizes (median = 17 depression cases) and used exploratory methods to set sample-specific cutoff scores that varied substantially across studies. A nurse-delivered intervention for MDD reduced depressive symptoms moderately (effect size = 0.37). CONCLUSIONS: The one treatment study reviewed reported modest improvement in depressive symptoms, but no evidence was found on whether or not depression screening in cancer patients, either alone or in the context of optimal depression care, improves depression outcomes compared to usual care. Depression screening in cancer should be evaluated in a RCT in which all patients identified as depressed, either through screening or via physician recognition and referral in a control group, have access to comprehensive depression care.

RESUMEN

OBJECTIVE: The implantable cardioverter defibrillator (ICD) is used to treat life-threatening ventricular arrhythmias and in the prevention of sudden cardiac death. A significant proportion of ICD patients experience psychological symptoms including anxiety, depression or both, which in turn can impact adjustment to the device. The objective of this systematic review was to assess the prevalence of anxiety and depression or symptoms of anxiety and depression among adults with ICDs. METHODS: Search of MEDLINE®, CINAHL®, PsycINFO®, EMBASE® and Cochrane® for English-language articles published through 2009 that used validated diagnostic interviews to diagnose anxiety or depression or self-report questionnaires to assess symptoms of anxiety or depression in adults with an ICD. RESULTS: Forty-five studies that assessed over 5000 patients were included. Between 11% and 28% of patients had a depressive disorder and 11-26% had an anxiety disorder in 3 small studies (Ns=35-90) that used validated diagnostic interviews. Rates of elevated symptoms of anxiety (8-63%) and depression (5-41%) based on self-report questionnaires ranged widely across studies and times of assessment. Evidence was inconsistent on rates pre- versus post-implantation, rates over time, rates for primary versus secondary prevention, and for shocked versus non-shocked patients. CONCLUSION: Larger studies utilizing structured interviews are needed to determine the prevalence of anxiety and depression among ICD patients and factors that may influence rates of anxiety and depressive disorders. Based on existing data, it may be appropriate to assume a 20% prevalence rate for both depressive and anxiety disorders post-ICD implant, a rate similar to that in other cardiac populations.

RESUMEN

CONTEXT: Disclosure of conflicts of interest (COIs) from pharmaceutical industry study funding and author-industry financial relationships is sometimes recommended for randomized controlled trials (RCTs) published in biomedical journals. Authors of meta-analyses, however, are not required to report COIs disclosed in original reports of included RCTs. OBJECTIVE: To investigate whether meta-analyses of pharmacological treatments published in high-impact biomedical journals report COIs disclosed in included RCTs. DATA SOURCES AND STUDY SELECTION: We selected the 3 most recent meta-analyses of patented pharmacological treatments published January 2009 through October 2009 in each general medicine journal with an impact factor of at least 10; in high-impact journals in each of the 5 specialty medicine areas with the greatest 2008 global therapeutic sales (oncology, cardiology, respiratory medicine, endocrinology, and gastroenterology); and in the Cochrane Database of Systematic Reviews. DATA EXTRACTION: Two investigators independently extracted data on disclosed study funding, author-industry financial ties, and author employment from each meta-analysis, from RCTs included in each meta-analysis, and on whether meta-analyses reported disclosed COIs of included RCTs. RESULTS: Of 29 meta-analyses reviewed, which included 509 RCTs, only 2 meta-analyses (7%) reported RCT funding sources; and 0 reported RCT author-industry ties or employment by the pharmaceutical industry. Of 318 meta-analyzed RCTs that reported funding sources, 219 (69%) were industry funded; and 91 of 132 (69%) that reported author financial disclosures had 1 or more authors with pharmaceutical industry financial ties. In 7 of the 29 meta-analyses reviewed, 100% of included RCTs had at least 1 form of disclosed COI (pharmaceutical industry funding, author-industry financial ties, or employment), yet only 1 of these 7 meta-analyses reported RCT funding sources, and 0 reported RCT author-industry ties or employment. CONCLUSION: Among a group of meta-analyses of pharmacological treatments published in high-impact biomedical journals, information concerning primary study funding and author COIs for the included RCTs were only rarely reported.

RESUMEN

Forming implementation intentions ('If I encounter situation X, then I will perform behaviour Y!') increases the probability of carrying out goals. This study tested the hypothesis that mental imagery targeting key elements of implementation intentions further increases goal achievement. The residents of a student residence were assigned the goal of consuming extra portions of fruit every day for 7 days and randomly assigned to one of four conditions: control (active rehearsal), implementation intentions, goal intention mental imagery or mental imagery targeted to the implementation intentions. Among low fruit consumers, but not high fruit consumers, fruit consumption at follow-up was higher in the targeted mental imagery group than in the other group, with the lowest fruit consumption in the control group. The findings suggest that it may be beneficial to use targeted mental imagery when forming implementation intentions.

RESUMEN

OBJECTIVE: The most reliable evidence for evaluating healthcare interventions comes from well-designed and conducted randomized controlled trials (RCTs). The extent to which published RCTs reflect the efficacy of interventions, however, depends on the completeness and accuracy of published results. The Consolidated Standards of Reporting Trials statement, initially developed in 1996, provides guidelines intended to improve the transparency of published RCT reports. A policy of the International Committee of Medical Journal Editors, initiated in 2005, requires clinical trials published in member journals to be registered in publicly accessible registries prior to patient enrollment. The objective of this study was to assess the clarity of outcome reporting, proportion of registered trials, and adequacy of outcome registration in RCTs published in top behavioral health journals. METHODS: Eligible studies were primary or secondary reports of RCTs published in Annals of Behavioral Medicine, Health Psychology, Journal of Psychosomatic Research, and Psychosomatic Medicine from January 2008 to September 2009. Data were extracted for each study on adequacy of outcome reporting and registration. RESULTS: Of 63 articles reviewed, only 25 (39.7%) had adequately declared primary or secondary outcomes, whereas 38 (60.3%) had multiple primary outcomes or did not define outcomes. Only 13 studies (20.6%) were registered. Only 1 study registered sufficiently precise outcome information to compare with published outcomes, and registered and published outcomes were discrepant in that study. CONCLUSION: Greater attention to outcome reporting and trial registration by researchers, peer reviewers, and journal editors will increase the likelihood that effective behavioral health interventions are readily identified and made available to patients.

RESUMEN

OBJECTIVE: To assess the efficacy of a previsit questionnaire (PVQ), implemented without formal training, that was designed to screen for biomedical and psychosocial health issues and concerns among adolescent patients in a hospital-based primary care clinic, and to examine the subsequent action taken for health issues and concerns identified with the PVQ. DESIGN: Retrospective review of adolescent medical charts, using a pre-post design. SETTING: An outpatient primary care clinic located in an urban teaching hospital in Montreal, Que. PARTICIPANTS: A total of 210 adolescent patients aged 13 to 19 who visited the clinic between 2000 and 2004. MAIN OUTCOME MEASURES: The type (medical vs psychosocial) and number of issues detected and actions taken by physicians in one-to-one consultations with adolescent patients 2 years before (2000-2002) and 2 years after (2002-2004) PVQ implementation, as noted in the patients' medical charts. RESULTS: In total, 105 charts were reviewed for each group. An increase in the number of psychosocial issues was detected following the introduction of the PVQ. An increase in the frequency of action taken for psychosocial concerns and a decrease in the frequency of medical action taken by physicians were found after PVQ implementation. More notations related to psychosocial concerns were also found in the adolescents' charts after introduction of the PVQ. CONCLUSION: A PVQ is an effective strategy to improve adolescent screening for psychosocial issues and concerns. Implementing such a questionnaire requires no training and can therefore be easily incorporated into clinical practice.

RESUMEN

GOALS OF WORK: Distress is defined by the National Comprehensive Cancer Network as a multifactorial unpleasant emotional experience of a psychological, social, and/or spiritual nature that may interfere with the ability to cope effectively with cancer. We investigated the prevalence and associated symptoms of distress in newly diagnosed lung cancer patients. PATIENTS AND METHODS: Between November 2005 and July 2007, 98 newly diagnosed lung cancer patients completed an assessment. The Distress Thermometer (DT) and Edmonton Symptom Assessment Scale (ESAS) were used as screening tools. MAIN RESULTS: Fifty (51%) patients reported clinically significant distress (>or=4) on the DT. Of those, 26 (52%) patients reported high levels of depression, nervousness, or both on ESAS. The remaining 24 (48%) patients had elevated levels of distress but no significant depression or nervousness. A correlation between the DT and the total ESAS score was observed (Pearson correlation = 0.46). The ten items of the ESAS together explained 46% of the variability in DT scores. The depression and nervousness ESAS items were significant predictors of DT score (p < 0.01 for both items). However, once the two psychosocial items, depression and nervousness, were removed from the total ESAS score, leaving only physical symptoms and the sleeplessness item, the predictive power of the model decreased to R(2) = 0.12. CONCLUSIONS: The prevalence of distress in lung cancer patients is high. The DT appears to discriminate between physical and emotional distress. This easily measured score may determine which patients require further intervention for emotional distress.

RESUMEN

A number of long-term care facilities in North Carolina have adopted ways to improve the dining experience for long-term care residents. Wall murals and dining room themes help to create a pleasant atmosphere that also might stimulate resident imagination. Aroma therapies are also positive stimulants that increase the appetite and pleasure in eating. Flavor and food presentation are probably some of the most obvious modifications. We can all understand the desire to have our food taste and look good. There are probably even more ideas that could make eating in a nursing home more pleasant and home-like. Efforts Like these are critical to stemming weight loss among residents and also to maintaining resident independence to the extent possible. We hope more facilities across the state will use and build on these ideas as they try to maximize their residents' quality of life.
