Case-finding instruments for depression. Two questions are as good as many

Chronic diseases and related risk factors among low-income mothers

The aim is to describe the burden of chronic disease and related risk factors among low-income women of reproductive age. We analyzed population-based data from the 2005-2006 Pregnancy Risk Assessment Monitoring System (PRAMS) for 14,990 women with a live birth in 7 states. We examined the prevalence of selected chronic diseases and related risk factors (preexisting diabetes, gestational diabetes, chronic hypertension, pregnancy-induced hypertension, obesity, smoking or binge drinking prior to pregnancy, smoking or excessive weight gain during pregnancy, and postpartum depressive symptoms) by Federal Poverty Level (FPL) (≤100% FPL; 101-250% FPL; >250% FPL). Approximately one-third of women were low-income (≤100% FPL), one-third were near-low-income (101-250% FPL), and one-third were higher-income (>250% FPL). Compared to higher-income women, low-income women were significantly more likely to smoke before or during pregnancy (34.2% vs. 14.4%, and 24.8% vs. 5.4%, respectively), be obese (22.2% vs. 16.0%), experience postpartum depressive symptoms (23.3% vs. 7.9%), have 3 or more chronic diseases and/or related risk factors (28.1% vs. 14.4%) and be uninsured before pregnancy (48.9% vs. 4.8%). Low-income women of reproductive age experienced a higher prevalence of selected chronic diseases and related risk factors. Enhancing services for these women in publicly-funded family planning clinics may help reduce disparities in pregnancy and long-term health outcomes in the poor.

Geographically-based discrimination is a social determinant of mental health in a deprived or stigmatized area in Japan: a cross-sectional study

Perceived discrimination has been shown to be associated with health. However, it is uncertain whether discrimination based on geographical place of residence (geographically-based discrimination), such as Buraku or Nishinari discrimination in Japan, is associated with health. We conducted a cross-sectional study (response rate = 52.3%) from February to March 2009 in a Buraku district of Nishinari ward in Osaka city, one of the most deprived areas in Japan. We implemented sex-stratified and education-stratified multivariate regression models to examine the association between geographically-based discrimination and two mental health outcomes (depressive symptoms and diagnosis of mental illness) with adjustment for age, socioeconomic status, social relationships and lifestyle factors. A total of 1994 persons aged 25-79 years (928 men and 1066 women) living in the district were analyzed. In the fully-adjusted model, perceived geographically-based discrimination was significantly associated with depressive symptoms and diagnosis of mental illness. It was more strongly associated among men or highly educated people than among women or among less educated people. The effect of geographically-based discrimination on mental health is independent of socioeconomic status, social relationship and lifestyle factors. Geographically-based discrimination may be one of the social determinants of mental health.

Major depressive disorder in patients with rheumatoid arthritis

OBJECTIVE

To investigate the point prevalence of major depressive disorder (MDD) as diagnosed by the Mini-International Neuropsychiatric Interview (M.I.N.I) in patients with rheumatoid arthritis (RA) and to determine whether MDD is related to features of RA disease, such as disease activity or physical dysfunction.

METHODS

Of the patients with RA who participated in the IORRA survey conducted in October 2005, 162 were evaluated using the M.I.N.I., the Center for Epidemiologic Studies-Depression (CES-D) scale, and the two-question depression screen for MDD. RA clinical features were obtained from the concomitant IORRA cohort database. Relationships between MDD and RA disease features were analyzed by the Wilcoxon rank sum test and Pearson's chi-square test.

RESULTS

The point prevalence of MDD as diagnosed by the M.I.N.I. was 6.8 % in our Japanese patients with RA. The percentage of depressive patients was determined to be 23.5, 17.3, or 7.4 % according to the CES-D scale with cut-off points of 16, 19, or 27, respectively, and 14.2 % according to the two-question depression screen. The best cut-off point for CES-D for risk of MDD diagnosed by M.I.N.I. in this study was determined to be 23, with 11.7 % depressive patients having the highest sum of sensitivity and specificity. No relationship between MDD and RA disease activity was detected.

CONCLUSION

By using the well-established structural interview instrument M.I.N.I., we determined the point prevalence of MDD in the RA patients enrolled in this study to be 6.8 %, leading to the conclusion that concomitant MDD does not seem to influence disease activity in RA patients.

Predicting 7-day and 3-month functional outcomes after an ED visit for acute nontraumatic low back pain

BACKGROUND

Recent work has shown that two-thirds of patients report functional disability 1 week after an emergency department (ED) visit for nontraumatic musculoskeletal low back pain (LBP). Nearly half of these patients report functional disability 3 months later. Identifying high-risk predictors of functional disability at each of these 2 time points will allow emergency clinicians to provide individual patients with an evidence-based understanding of their risk of protracted symptoms.

OBJECT

The aim of the present study was to determine whether 5 high-risk features previously identified in various primary care settings predict poor functional outcomes among patients in the ED. The hypothesized predictors are as follows: LBP-related functional disability at baseline, radicular signs, depression, a work-related injury, or a history of chronic or recurrent LBP before the index episode.

METHODS

We conducted a prospective observational cohort study of patients in the ED with a chief complaint of nontraumatic LBP, which the ED attending physician classified as musculoskeletal. We interviewed patients in the ED before discharge and performed a baseline assessment of functional disability using the 24-item Roland-Morris questionnaire. We also trichotomized the patient's baseline history of LBP into chronic (defined as 30 straight days with continuous LBP or a history of acute exacerbations more frequently than once per week); episodic (acute exacerbations more frequently than once per year but less frequently than once per week), or rarely/never (less frequently than once per year or no history of LBP). We performed telephone follow-up 1 week and 3 months after ED discharge using a scripted closed-question data collection instrument. The primary outcome was any functional limitation attributable to LBP at 1 week and 3 months, defined as a score greater than zero on the Roland-Morris questionnaire. We used logistic regression, adjusted for age, sex, and educational level, to assess the independent association between functional disability and each of the 5 hypothesized predictors listed above.

RESULTS

We approached 894 patients for participation and included 556. We obtained follow-up on 97% and 92% of our sample at 1 week and 3 months, respectively. Two of the 5 hypothesized variables predicted functional disability at both time points: higher baseline Roland-Morris score (odds ratio [OR], 4.3; 95% confidence interval [CI], 2.6-6.9) and chronic LBP (OR, 2.3; 95% CI, 1.1-4.8) were associated with 7-day functional disability. These same 2 variables predicted functional disability 3 months after ED discharge-higher baseline Roland-Morris score (OR, 2.3; 95% CI, 1.4-3.9) and chronic LBP (OR, 2.8; 95% CI, 1.5-5.2). The remaining 3 hypothesized predictors (depression, radicular signs, and on-the-job injury) did not predict functional outcome at either time point.

CONCLUSIONS

Patients in the ED with worse baseline functional impairment and a history of chronic LBP are 2 to 4 times most likely to have poor short- and longer-term outcomes.

Case identification of depression in patients with chronic physical health problems: a diagnostic accuracy meta-analysis of 113 studies

BACKGROUND

Depression is more likely in patients with chronic physical illness, and is associated with increased rates of disability and mortality. Effective treatment of depression may reduce morbidity and mortality. The use of two stem questions for case finding in diabetes and coronary heart disease is advocated in the Quality and Outcomes Framework, and has become normalised into primary care.

AIM

To define the most effective tool for use in consultations to detect depression in people with chronic physical illness.

DESIGN

Meta-analysis.

METHOD

The following data sources were searched: CENTRAL, CINAHL, Embase, HMIC, MEDLINE, PsycINFO, Web of Knowledge, from inception to July 2009. Three authors selected studies that examined identification tools and used an interview-based ICD (International Classification of Diseases) or DSM (Diagnostic and statistical Manual of Mental Disorders) diagnosis of depression as reference standard. At least two authors independently extracted study characteristics and outcome data and assessed methodological quality.

RESULTS

A total of 113 studies met the eligibility criteria, providing data on 20,826 participants. It was found that two stem questions, PHQ-9 (Patient Health Questionnaire), the Zung, and GHQ-28 (General Health Questionnaire) were the optimal measures for case identification, but no method was sufficiently accurate to recommend as a definitive case-finding tool. Limitations were the moderate-to-high heterogeneity for most scales and the facts that few studies used ICD diagnoses as the reference standard, and that a variety of methods were used to determine DSM diagnoses.

CONCLUSION

Assessing both validity and ease of use, the two stem questions are the preferred method. However, clinicians should not rely on the two-questions approach alone, but should be confident to engage in a more detailed clinical assessment of patients who score positively.

Use of the Patient Health Questionnaire-2 to predict suicidal ideations in patients taking varenicline

Varenicline, when taken for smoking cessation, has been associated with suicidal ideations (SI), but the incidence and risk factors for SI are largely unknown. The aim of this paper was to describe the incidence and pretreatment patient factors that are associated with SI when taking varenicline. We conducted a smoking cessation trial of 217 patients at a single center, all of whom took varenicline. Between 6 and 18 months after study completion (when the risk for SI became known), we successfully contacted 72 (response rate 33%) and queried them for SI during varenicline treatment. Of these, 4 (6%) had SI. Self-reported history of depression was not associated with SI (p = 0.11), but depressive symptoms at the time of varenicline initiation as measured by the Patient Health Questionnaire-8 (p = 0.004) and Patient Health Questionnaire-2 (p = 0.007) were associated with SI. The Patient Health Questionnaire-2 (which is only two questions) had a sensitivity of 75% and a specificity of 90% to predict SI. We conclude that current depressive symptoms, not necessarily a history of depression, are associated with SI when taking varenicline for smoking cessation. Providers should consider screening for depressive symptoms before treatment with varenicline. (Am J Addict 2012;00:1-7).

Prevalence and co-occurrence of upper and lower functional gastrointestinal symptoms in patients eligible for bariatric surgery

BACKGROUND

Obesity is considered as a risk factor for many functional digestive disorders. The aim of the present study was to evaluate the prevalence and the association of functional digestive symptoms affecting the upper and the lower digestive tract in patients eligible for bariatric surgery.

METHODS

Before surgery, 120 consecutive patients with normal upper endoscopy (7.5% males, mean BMI 44 ± 6 m/kg(2)) have filled a standard questionnaire in order to evaluate the presence of depressive symptoms and functional digestive disorders according to the Rome criteria. The major symptoms (esophageal, gastroduodenal, anorectal, and abdominal pain) were coded as dichotomous variables. Data analysis was performed using multivariate logistic regression with a backwards selection procedure adjusted only for the variables that were significant in univariate analysis (p < 0.05).

RESULTS

Functional symptoms were present in 89% of the subjects (2.5 functional digestive symptoms/subject). Depression symptoms were found in 43% of the patients. Esophageal symptoms were independent predictors for the presence of gastric, bowel, and anorectal symptoms. Functional abdominal pain and bowel symptoms were present, respectively, in 19% and 84% of the patients. Approximately half of the patients have specific functional bowel disorders (28.6% constipation, 18% irritable bowel syndrome, 18% diarrhea, 1% bloating) and 35.7% have non-specific bowel disorders. Anorectal symptoms were found in 40% of the patients: difficult defecation in 32% and fecal incontinence in 9.8% of the patients. Depression was an independent predictor for anorectal symptoms.

CONCLUSIONS

This study shows the high prevalence of functional bowel symptoms in patients complaining of morbid obesity.

An assessment of the screening performance of a single-item measure of depression from the Edmonton Symptom Assessment Scale among chronically ill hospitalized patients

CONTEXT

Few studies have examined the validity of using a single item from the Edmonton Symptom Assessment Scale (ESAS) for screening for depression.

OBJECTIVES

To examine the screening performance of the single-item depression question from the ESAS in chronically ill hospitalized patients.

METHODS

A total of 162 chronically ill inpatients aged 65 and older completed a survey after admission that included the well-validated, 15-item Geriatric Depression Scale (GDS-15) and four single-item screening questions for depression based on the ESAS question, using two different time frames ("now" and "in the past 24 hours") and two response categories (a 0-10 numeric rating scale [NRS] and a categorical scale: none, mild, moderate, and severe).

RESULTS

The GDS-15 categorized 20% (n = 33) of participants as possibly being depressed with a score ≥ 6. The NRS for depression "now" achieved the highest level of sensitivity at a cutoff ≥ 1 (68.8%), and an acceptable level of specificity was obtained at a cutoff of ≥ 5 (82.2%). For depression "in the past 24 hours," a cutoff of ≥ 1 achieved a sensitivity of 68.8% and a cutoff of ≥ 7 a specificity of 80.3%. For the categorical scale, a cutoff of "none" provided the best level of sensitivity for depression "now" (65.6%) and "in the past 24 hours" (81.3%), with an acceptable level of specificity being obtained at ≥"mild" (68.8%) and ≥"moderate" (68.8%), respectively.

CONCLUSION

These single-item measures were not effective in screening for probable depression in chronically ill patients regardless of the time frame or the response format used, but a cutoff of ≥ 5 or "mild" or greater did achieve sufficient specificity to raise clinical suspicion.

An internet survey of use, opinions and preferences for smoking cessation medications: nicotine, varenicline, and bupropion

INTRODUCTION

We assessed use, compliance and preferences among smoking cessation medications in a "real world" sample of current and former smokers.

METHODS

Internet survey on a smoking cessation website (French/English, 2008-2010) to assess use of nicotine replacement therapies (NRT), varenicline, and bupropion.

RESULTS

There were 885 participants (39% current smokers, 61% former smokers), the majority of the sample (70%) was female. The most frequently used medications were, in order: patches (40%), varenicline (23%), nicotine gum (16%), nicotine lozenge/tablet (10%), bupropion (8%), and inhaler (3%). Satisfaction, perceived relief of craving/withdrawal and effectiveness were best for varenicline and lowest for gum. In current users, duration of use was longest for gum (121 days), lozenge/tablet (152 days) and shortest for patch (25 days). Daily use was good for lozenge (9 pieces/day) but less than recommended for gum (6 pieces/day) and inhaler (2 plugs/day). People who tried more than 1 medication found varenicline more effective and satisfactory than NRT or bupropion; and users preferred patch to gum. By smoking status, former smokers had more education, reported greater use of medications (daily, over time) and reported more satisfaction with medications than current smokers.

CONCLUSIONS

An Internet survey showed smoking cessation medications differed significantly in perceived effectiveness, satisfaction, and smoking status (former vs. current smoking). Except for lozenge/tablet, insufficient daily use remained a problem with acute NRTs. For all medications, improving outcome may require better instruction for proper use, approval of new indications (precessation) or development of new medications that bypass compliance issues that undermine success.

Lack of preparation, physical health after childbirth, and early postpartum depressive symptoms

BACKGROUND

Prior research has not examined the association of patient expectations or preparation by providers for the postpartum experience with depressive symptoms. We investigated whether lack of preparation for the postpartum experience and physical health after uncomplicated childbirth were associated with early postpartum depressive symptoms.

METHODS

We conducted a telephone survey of 720 early postpartum mothers in New York City. Mothers reported on depressive symptoms, physical symptoms, provider preparation for the postpartum experience, and other factors.

RESULTS

Nearly 39% of patients reported depressive symptoms; 24% did not feel adequately prepared by their provider for the postpartum experience. Mothers reported a range of physical symptoms: 98% reported daily vaginal bleeding, 79% reported cesarean section or episiotomy site pain, 82% reported breast pain, and 32% reported urinary incontinence. Patients who reported inadequate preparation by their provider were more likely to report depressive symptoms compared with patients who reported adequate preparation (53% vs. 35%, p < 0.001). In a multivariable model predicting postpartum depressive symptoms, adjusted odds ratios (ORs) remained elevated for perceived lack of preparation for the postpartum experience, more physical symptoms, and more physical functional limitations.

CONCLUSIONS

Further research is needed to investigate whether preparing patients for expected health consequences after pregnancy may reduce the incidence of early postpartum depressive symptoms.

Low back pain

The Orthopaedic Section of the American Physical Therapy Association (APTA) has an ongoing effort to create evidence-based practice guidelines for orthopaedic physical therapy management of patients with musculoskeletal impairments described in the World Health Organization’s International Classification of Functioning, Disability, and Health (ICF). The purpose of these low back pain clinical practice guidelines, in particular, is to describe the peer-reviewed literature and make recommendations related to (1) treatment matched to low back pain subgroup responder categories, (2) treatments that have evidence to prevent recurrence of low back pain, and (3) treatments that have evidence to influence the progression from acute to chronic low back pain and disability.

Diagnostic accuracy of case-finding questions to identify perinatal depression

BACKGROUND

Guidelines for perinatal mental health care recommend the use of two case-finding questions about depressed feelings and loss of interest in activities, despite the absence of validation studies in this context. We examined the diagnostic accuracy of these questions and of a third question about the need for help asked of women receiving perinatal care.

METHODS

We evaluated self-reported responses to two case-finding questions against an interviewer-assessed diagnostic standard (DSM-IV criteria for major depressive disorder) among 152 women receiving antenatal care at 26-28 weeks' gestation and postnatal care at 5-13 weeks after delivery. Among women who answered "yes" to either question, we assessed the usefulness of asking a third question about the need for help. We calculated sensitivity, specificity and likelihood ratios for the two case-finding questions and for the added question about the need for help.

RESULTS

Antenatally, the two case-finding questions had a sensitivity of 100% (95% confidence interval [CI] 77%-100%), a specificity of 68% (95% CI 58%-76%), a positive likelihood ratio of 3.03 (95% CI 2.28-4.02) and a negative likelihood ratio of 0.041 (95% CI 0.003-0.63) in identifying perinatal depression. Postnatal results were similar. Among the women who screened positive antenatally, the additional question about the need for help had a sensitivity of 58% (95% CI 38%-76%), a specificity of 91% (95% CI 78%-97%), a positive likelihood ratio of 6.86 (95% CI 2.16-21.7) and a negative likelihood ratio of 0.45 (95% CI 0.25-0.80), with lower sensitivity and higher specificity postnatally.

INTERPRETATION

Negative responses to both of the case-finding questions showed acceptable accuracy for ruling out perinatal depression. For positive responses, the use of a third question about the need for help improved specificity and the ability to rule in depression.

Comparison of two depression measures for predicting stroke outcomes

OBJECTIVES

Little is known about the effect of lifetime history of depression on ischemic stroke outcomes. This study compared a measure of current symptoms of depression at the time of the stroke and a measure of lifetime history of depression for their ability to predict quality of life and functioning at 3 and 12 months after stroke.

METHODS

A cohort of 460 ischemic stroke patients from the 2005 Greater Cincinnati/North Kentucky Stroke Study was assessed within 2 weeks of the stroke, including the 10-item Center for Epidemiological Studies Depression Scale (CESD) for current symptoms of depression. Lifetime history of depression was also assessed by a 2-question measure at 3 and 12 months after stroke. Two outcome measures, Stroke Specific Quality of Life (SSQOL) and the modified Rankin Scale (mRS) to assess functional status, were also collected at 3 and 12 months.

RESULTS

Of the 322 survivors included in the analysis, 52.2% reported depression on at least one measure. Both current symptoms and lifetime history of depression predicted poor functional outcomes and poor quality of life at 3 and 12 months, after adjustment for age, race, sex, prior stroke, baseline functional status, and stroke severity. The combination of depression measures was a better predictor of poor outcomes than either measure alone.

CONCLUSION

Depression by either measure was a frequent, substantial, and independent predictor of poor outcomes at 3 and 12 months after stroke. Stroke outcomes studies should further examine the predictive value of assessing both depressive symptoms at the time of the stroke and lifetime history of depression.

Resident physician well-being and assessments of their knowledge and clinical performance

BACKGROUND

Medical knowledge and clinical performance ratings are major criteria for assessing the competence of resident physicians. However, these assessments may be influenced by residents' mental health. The relationship between residents' well-being and empathy and assessments of their global performance remains unclear.

OBJECTIVE

To determine whether resident well-being and empathy are associated with assessments of their medical knowledge and clinical performance.

DESIGN, SETTING, AND PARTICIPANTS

We studied 730 clinical performance assessments completed by peers, supervising residents, and allied health professionals; 193 mini-clinical evaluation exercise (mini-CEX) evaluations; and 260 in-training examinations (ITE) of Mayo Clinic internal medicine residents between January 2009 and August 2010. Multivariate generalized estimating equations were used to evaluate associations between residents' well-being and empathy and assessments of their knowledge and clinical performance.

MEASUREMENTS

Independent variables were empathy using the Interpersonal Reactivity Index (IRI), burnout using the Maslach Burnout Inventory, depression using a standardized two-question screening instrument, and quality of life using a Linear Analog Self-Assessment item and the Medical Outcomes Study Short Form (SF-8). Dependent variables were mini-CEX, ITE, and the validated six-item Mayo clinical performance assessment.

RESULTS

202 residents (64.7%) provided both well-being and at least one category of assessment data. In multivariate models, residents' scores on the IRI empathy measure of "the tendency to adopt the psychological view of others" were associated with higher peer ratings on "desirability as a physician for a family member" (beta = 0.023, 95% CI = 0.007-0.039, p = 0.004). Additionally, burnout was associated with higher supervisor ratings of communication (beta = 0.309, 95% CI = 0.100-0.517, p = 0.004). There were no observed associations between ITE or mini-CEX scores and resident quality of life, burnout, fatigue, depression, or empathy.

CONCLUSIONS

Most dimensions of resident well-being were not associated with residents' knowledge scores and assessments of their clinical performance by other members of the health care team, which supports the trustworthiness of these measures. Nonetheless, correlations of resident empathy and burnout with assessments completed by peers and supervising residents suggest that some ratings of residents may be influenced by interpersonal factors.

The channel capacity of a diagnostic test as a function of test sensitivity and test specificity

We apply the information theory concept of "channel capacity" to diagnostic test performance and derive an expression for channel capacity in terms of test sensitivity and test specificity. The expected value of the amount of information a diagnostic test will provide is equal to the "mutual information" between the test result and the disease state. For the case in which only two test results and two disease states are considered, mutual information, I(D;R), is a function of sensitivity, specificity, and the pretest probability of disease. The channel capacity of the test is the maximal value of I(D;R) for a given sensitivity and specificity. After deriving an expression for I(D;R) in terms of sensitivity, specificity, and pretest probability, we solve for the value of pretest probability that maximizes I(D;R). Channel capacity is obtained by using this value of pretest probability to calculate I(D;R). Channel capacity provides a convenient and meaningful single parameter measure of diagnostic test performance. It quantifies the upper limit of the amount of information a diagnostic test can be expected to provide about a patient's disease state.

Should methodological filters for diagnostic test accuracy studies be used in systematic reviews of psychometric instruments? A case study involving screening for postnatal depression

BACKGROUND

Challenges exist when searching for diagnostic test accuracy (DTA) studies that include the design of DTA search strategies and selection of appropriate filters. This paper compares the performance of three MEDLINE search strategies for psychometric diagnostic test accuracy (DTA) studies in postnatal depression.

METHODS

A reference set of six relevant studies was derived from a forward citation search via Web of Knowledge. The performance of the 'target condition and index test' method recommended by the Cochrane DTA Group was compared to two alternative strategies which included methodological filters. Outcome measures were total citations retrieved, sensitivity, precision and associated 95% confidence intervals (95%CI).

RESULTS

The Cochrane recommended strategy and one of the filtered search strategies were equivalent in performance and both retrieved a total of 105 citations, sensitivity was 100% (95% CI 61%, 100%) and precision was 5.2% (2.6%, 11.9%). The second filtered search retrieved a total of 31 citations, sensitivity was 66.6% (30%, 90%) and precision was 12.9% (5.1%, 28.6%). This search missed the DTA study with most relevance to the DTA review.

CONCLUSIONS

The Cochrane recommended search strategy, 'target condition and index test', method was pragmatic and sensitive. It was considered the optimum method for retrieval of relevant studies for a psychometric DTA review (in this case for postnatal depression). Potential limitations of using filtered searches during a psychometric mental health DTA review should be considered.

Diurnal Evening Type is Associated with Current Smoking, Nicotine Dependence and Nicotine Intake in the Population Based National FINRISK 2007 Study

AIMS: To examine whether smoking habits, nicotine dependence (ND) and plasma cotinine levels differ by diurnal type. DESIGN: Data originated from the national FINRISK 2007 survey. Regression analyses were calculated to examine the association between diurnal type and smoking status, ND, and nicotine intake. PARTICIPANTS: 7091 FINRISK participants with smoking and diurnal type information and a subset of 1746 ever smokers with detailed smoking, and ND assessments. MEASUREMENTS: Diurnal type assessed with a six-item sum scale was categorized as morning, intermediate and evening type. Smoking status was determined as current (daily or occasional), former, and never smokers. ND was measured with the Fagerström Test for Nicotine Dependence (FTND), the Hooked on Nicotine Checklist (HONC), and the Nicotine Dependence Syndrome Scale (NDSS). For current smokers, plasma cotinine was analyzed as biochemical measurement of nicotine intake. FINDINGS: Evening type was associated with current smoking (OR=1.66, 95% CI 1.40, 1.97). A significant association with diurnal type was seen for FTND among men (beta= -0.46, 95% CI -0.72, -0.21), sexes combined for HONC (beta= -0.31, 95% CI -0.52, -0.11) and NDSS (beta= -0.86, 95% CI -1.43, -0.29) and for cotinine among men (beta= -0.73, 95% CI -1.16, -0.29). Adjustment for depressive symptoms attenuated the association of diurnal type with NDSS to be non-significant. CONCLUSIONS: Diurnal type was associated with multiple ND measures and nicotine intake, interestingly more so among men. Evening type persons are at higher risk of dependence, but depressive symptoms attenuates this association clearly.

Diabetes mellitus and comorbid depression: improvement of both diseases with milnacipran. A replication study (results of the Austrian Major Depression Diabetes Mellitus study group)

Comorbid depression is common in patients with type 2 diabetes mellitus and is associated with greater mortality risk and a higher incidence of diabetic complications and decreased quality of life. In an earlier pilot study, we found that treatment with the serotonin norepinephrine reuptake inhibitor antidepressant, milnacipran, significantly improved metabolic parameters in diabetic patients with comorbid depression who had an antidepressant response. We sought to replicate these results in a larger cohort (n = 135). Patients received milnacipran and metformin for 6 months and metabolic parameters and depressive symptoms were measured at baseline and after 3 and 6 months. At the end of the study, 72.6% of patients had an antidepressant response (≥50% reduction of baseline Beck Depression Inventory score). Overall, there was significant improvement in the metabolic and anthropometric parameters measured. The number of patients with glycated hemoglobin > 8% (>63.9 mmol/mol), an indicator of poor metabolic control requiring intensive therapeutic intervention, decreased from 31.9% at baseline to 11.9% during the study. As found in the pilot study, levels of total cholesterol and triglycerides were only significantly decreased in antidepressant responders. Body weight was significantly reduced in both responders and nonresponders but the effect size was significantly greater in the responder group. In contrast to the pilot study, fasting blood glucose and glycated hemoglobin were significantly decreased to a similar extent in both antidepressant-responders and nonresponders. The present study thus replicates some of the original findings. The main difference between the present and the pilot study is that in the larger cohort significant reductions in fasting blood glucose and glycated hemoglobin were found in all patients irrespective of whether or not they responded to antidepressant treatment. The present data underline the importance of diagnosis and treatment of comorbid depression in patients with type 2 diabetes mellitus with milnacipran.

Combination use of Beck Depression Inventory and two-question case-finding instrument as a screening tool for depression in the workplace

OBJECTIVES

The present study aimed to validate screening tools that could be used to identify depression among workers.

DESIGN

Diagnostic test study.

SETTINGS

Workers from three Japanese companies agreed to participate.

PARTICIPANTS

Recruitment for the group 1 occurred between January 2001 and February 2004, and 89 participants (81 men and 8 women with a mean age of 38.4±6.6 years) (98.8%) took part in the study. Recruitment for the group 2 occurred between July 2000 and February 2004, and 1500 participants (1408 men and 92 women with a mean age of 40.9±7.2 years) (94.2%) took part in the study. Demographic data are shown in supplementary table 1.

PRIMARY AND SECONDARY OUTCOME MEASURES

the Beck Depression Inventory (BDI) and a two-question case-finding instrument (TQI) were administered to 89 workers and Mini-International Neuropsychiatric Interview was conducted to verify the diagnosis of depression. A second group of 1500 workers completed the BDI and TQI to detect possible sample bias for the distribution of depression. Specificity, sensitivity and positive predictive value were calculated in order to obtain the optimal cut-off scores for BDI and TQI and receiver operating characteristic curves, and Youden Index were applied to further refine the optimal cut-off scores.

RESULTS

When paired together, BDI score ≥10 and TQI score of 2 adequately identified workers who had major depressive disorder and those who had other psychiatric disorders that are frequently comorbid with major depressive disorder.

CONCLUSIONS

The combination of BDI score ≥10 and TQI score of 2 can adequately screen for current and potential cases of depression among workers. Furthermore, BDI and TQI offer the advantage of being relatively easy to administer to a large number of workers. Early detection of depression could improve treatment outcomes and decrease economic burden.

Longer term health of young and middle-aged adults following unintentional falls at home resulting in hospitalisation

Unintentional falls at home are a common cause of admissions to hospital amongst young and middle-aged adults. This population-based study investigated the longer-term health, physical and psychological outcomes following such injuries, and the predictors of these sequelae.

METHOD

Individuals aged 25-60 years admitted to hospital in the Auckland region between July 2005 and June 2006 following an unintentional fall at home were interviewed soon after the injury (baseline) and 15-months following the injury. Information collected at baseline on pre-injury status was analysed in relation to changes in general health and functioning, psychological outcomes, and role limitations at follow-up.

RESULTS

Of the 328 participants eligible for study, 251 (77%) completed the follow-up interview. Reductions in general health and overall functioning (compared with pre-injury status) were reported by 25% and 43% of participants, respectively. In multivariate analyses, predictors of specific adverse outcomes at follow-up included increasing age (reduction in functioning), lower limb injuries (reductions in general health and functioning); female gender (psychological sequelae); injury severity score ≥9 (anxiety and depression); and length of hospital stay (fear of falling and post-traumatic stress symptoms).

CONCLUSIONS

The significant longer-term reductions in health and levels of functioning reveal the importance of strengthening efforts to prevent falls amongst young and middle-aged adults, and identifying groups at increased risk of longer-term disability who could benefit from targeted interventions.

Recognizing cognitive and psychiatric changes in the post-highly active antiretroviral therapy era

Amid numerous complications that plague the health and quality of life of people living with HIV, neurocognitive and psychiatric illnesses pose unique challenges. While there remains uncertainty with respect to the pathophysiology surrounding these disorders, their adverse implications are increasingly recognized. Left undetected, they have the potential to significantly impact patient well being, adherence to antiretroviral treatment and overall health outcomes. As such, early identification of HIV-associated neurocognitive disorders (HAND) and psychiatric illnesses will be paramount in the proactive management of affected patients. The present review focuses on strategies to ensure optimal screening and detection of HAND, depression and substance abuse in routine practice. For each topic, currently available screening methods are discussed. These include identification of risk factors, recognition of relevant symptomatology and an update on validated screening tools that can be efficiently implemented in the clinical setting. Specifically addressed in the present review are the International HIV Dementia Scale, a novel screening equation and algorithm for HAND, as well as brief, validated, verbal questionnaires for detection of depression and substance abuse. Adequate understanding and usage of these screening mechanisms can ensure effective use of resources by distinguishing patients who require referral for more extensive diagnostic procedures from those who likely do not.

The reach of depression screening preceding treatment: are there patterns of patients' self-selection?

This study evaluated the reach of depression screening followed by treatment programs for subsyndromal depression and explored demographic and clinical characteristics of patients who were reached versus those who were not. A two-item Patient Health Questionnaire-Depression was sent to 4196 type 2 diabetic patients. Positively screened patients were interviewed to assess the severity of depression, and those with subclinical symptoms were invited to treatment groups. The reach of screening procedure was evaluated by the total response rate, proportion of positive depression screenings, and proportion of eligible patients entering treatment programs. Predictors of responsiveness to screening and of participation in treatment were determined using logistic regression. Of the 34% of patients who returned the questionnaire (n = 1442), 40% reported depressive symptoms and a need for professional help (n = 581). Age (OR = 1.06, 95% CI = 1.05-1.08), BMI (OR = 1.02, 95% CI = 1.00-1.04), HbA1C (OR = .92, 95% CI = .86-.99), and LDL-cholesterol (OR = .90, 95% CI = .81-1.00) correlated with response to screening. Willingness to accept treatment was predicted by professional status (OR = 3.24, 95% CI = 1.53-6.87), education (OR = 1.21, 95% CI = 1.05-1.38), and BMI (OR = .91, 95% CI = .85-.98). Older patients with better diabetes control were more likely to be reached by postal screening for depressive symptoms. Professionally inactive, better-educated persons and those with lower BMI were more likely to participate in the intervention for subsyndromal depression.

Patterns and predictors of treatment initiation and completion in patients with chronic hepatitis C virus infection

OBJECTIVES

Guidelines for hepatitis C (HCV) strongly recommend antiviral treatment for patients with more severe liver disease given their increased risk of developing cirrhosis and other liver-related complications. Despite the proven benefits of therapy, 70%-88% of patients chronically infected with HCV do not undergo treatment. The goal of this paper is to describe patterns of treatment initiation among patients with both mild and severe disease and to assess the factors that are associated with treatment initiation and completion.

METHODS

Subjects completed previously validated questionnaires to ascertain sociodemographic characteristics, choice predisposition, and clinical characteristics prior to meeting with the hepatologist to discuss treatment initiation and were followed for 12 months. We examined the association between patient characteristics and treatment patterns controlling for liver disease severity.

RESULTS

Of the 148 eligible subjects entered into our study, 55 (37%) initiated treatment during the 12-month follow-up period. Of the 86 subjects with severe liver disease, 43 (50%) initiated treatment. Financial barriers and geographic access to care were the most common reasons for treatment deferral. Of the 55 patients initiating treatment, 24 (44%) discontinued treatment, with intolerance of side effects being the most common reason for discontinuation. After adjusting for liver disease severity, patient choice predisposition (prior to discussion with their provider) was strongly associated with initiation of treatment, while sociodemographic characteristics were not.

CONCLUSION

Treatment initiation did align with current recommendations (patients with severe disease were more likely to initiate treatment), however, rates of treatment initiation and completion were low. Patient choice predisposition is the strongest predictor of treatment initiation, independent of disease severity. Improving individualized treatment outcomes for patients with chronic HCV requires efforts at identifying patients' choice predisposition, and improving access for those wishing to initiate therapy.

Implementation of a stroke self-management program: A randomized controlled pilot study of veterans with stroke

Secondary stroke prevention is championed as guideline care; yet there are no systematic programs offered. We developed a stroke self-management program to address this gap and pilot test the program. We conducted a randomized controlled trial at two Veterans Administration (VA) hospital sites where we recruited patients with an acute stroke to receive either the stroke program or an attention-control protocol over a 12-week period following hospital discharge. The stroke program included six sessions that facilitated stroke self management focusing on increasing self-efficacy to recover from stroke and engage in secondary stroke risk factor management. We surveyed outcomes at baseline, 3 and 6 months. We conducted an intention to treat analysis comparing the intervention to the control group on changes of outcomes between baseline and follow-up modeled by a linear model with fixed effects for treatment, visit, and the treatment by visit interaction adjusting for baseline. We recruited 63 participants (33 control and 30 intervention) who were hospitalized with a primary diagnosis of ischemic stroke. We found trends in differences between groups on self-efficacy to communicate with physicians, weekly minutes spent in aerobic exercise, and on dimensions of stroke-specific quality of life. This pilot study demonstrated the feasibility of delivering a stroke self-management program to recent stroke survivors in a healthcare organization. The program also demonstrated improvements in patient self-efficacy, self-management behaviors, specific dimensions of stroke-specific quality of life compared to a group that received an attention placebo program.

Internet-based CBT for depression with and without telephone tracking in a national helpline: randomised controlled trial

Background

Telephone helplines are frequently and repeatedly used by individuals with chronic mental health problems and web interventions may be an effective tool for reducing depression in this population.

Aim

To evaluate the effectiveness of a 6 week, web-based cognitive behaviour therapy (CBT) intervention with and without proactive weekly telephone tracking in the reduction of depression in callers to a helpline service.

Method

155 callers to a national helpline service with moderate to high psychological distress were recruited and randomised to receive either Internet CBT plus weekly telephone follow-up; Internet CBT only; weekly telephone follow-up only; or treatment as usual.

Results

Depression was lower in participants in the web intervention conditions both with and without telephone tracking compared to the treatment as usual condition both at post intervention and at 6 month follow-up. Telephone tracking provided by a lay telephone counsellor did not confer any additional advantage in terms of symptom reduction or adherence.

Conclusions

A web-based CBT program is effective both with and without telephone tracking for reducing depression in callers to a national helpline.

Comparing abrupt and gradual smoking cessation: a randomized trial

AIMS

To compare abrupt and gradual smoking cessation.

DESIGN AND SETTING

Randomized trial and observational study, Internet, 2007-2010.

PARTICIPANTS

Smokers with no strong preference for abrupt or gradual quitting were randomly assigned to quitting immediately (n=472), or to gradually reducing their cigarette consumption over 2 weeks and then quit (n=502). Smokers who strongly preferred to quit abruptly were instructed to do so immediately (n=2456), those who strongly preferred gradual were instructed to reduce their cigarette consumption over 2 weeks, then quit (n=1801). Follow-up was conducted 4 weeks after target quit dates.

FINDINGS

Those who preferred abrupt quitting were the most motivated to quit and the most confident in their ability to quit. At follow-up, quit rates were 16% in those who preferred abrupt cessation, 7% in those who preferred gradual cessation and 9% in those who had no preference (p<0.001). In the latter group, quit rates were equal for those randomized to abrupt or gradual (9%, p=0.97). In those who expressed a strong preference for either method, there were interactions between quitting method, motivation to quit and confidence in ability to quit: those who had low levels of motivation or low levels of confidence were more likely to quit at follow-up if they preferred and used abrupt rather than gradual.

CONCLUSIONS

In those who had no strong preference for either method, abrupt and gradual produced similar results. Those who preferred and used the abrupt method were more likely to quit than those who preferred and used the gradual method, in particular when they had low motivation and confidence.

Prevalence and psychosocial correlates of depressive symptoms among adolescents and adults with Klinefelter syndrome

PURPOSE

To determine the prevalence and psychosocial correlates of depressive symptoms among adolescents and adults with Klinefelter syndrome.

METHODS

Individuals (n = 310) aged 14-75 years with self-reported Klinefelter syndrome were recruited from regional and national support networks to complete a web-based survey. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Perceived consequences (Illness Perceptions Questionnaire), perceived stigma (Perceived Social Stigmatization Scale), and coping (Ways of Coping Checklist-Revised) were also measured and evaluated as correlates of depressive symptoms.

RESULTS

Overall, 68.8% of the study participants reported clinically significant levels of depressive symptoms as indicated by a Center for Epidemiologic Studies Depression Scale score ≥16. The use of emotion-focused coping strategies (P < 0.01), perceptions of stigmatization (P < 0.01), perceived negative consequences of Klinefelter syndrome (P < 0.01), and the importance of having children in the future (P < 0.05) were all significantly associated with depressive symptoms.

CONCLUSIONS

Individuals with Klinefelter syndrome may be at increased risk for depression. Routine screening for depressive symptoms and appropriate referral and evaluation may be warranted.

Loss of interest, depressed mood and impact on the quality of life: cross-sectional survey

BACKGROUND

Depressive symptoms and chronic disease have adverse effects on patients' health-related quality of life (H-RQOL). However, little is known about this effect on H-RQOL when only the two core depressive symptoms - loss of interest and depressed mood - are considered. The objective of this study is to investigate H-RQOL in the presence of loss of interest and depressed mood at a general medical outpatient unit.

METHODS

We evaluated 553 patients at their first attendance at a general medical outpatient unit of a teaching hospital. H-RQOL was assessed with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Depressed mood and loss of interest were assessed by the Primary Care Evaluation of Mental Disorders (PRIME-MD)-Patient Questionnaire. A physician performed the diagnosis of chronic diseases by clinical judgment and classified them in 13 possible pre-defined categories. We used multiple linear regression to investigate associations between each domain of H-RQOL and our two core depression symptoms. The presence of chronic diseases and demographic variables were included in the models as covariates.

RESULTS

Among the 553 patients, 70.5% were women with a mean age of 41.0 years (range 18-85, SD ± 15.4). Loss of interest was reported by 54.6%, and depressed mood by 59.7% of the patients. At least one chronic disease was diagnosed in 59.5% of patients; cardiovascular disease was the most prevalent, affecting 20.6% of our patients. Loss of interest and depressed mood was significantly associated with decreased scores in all domains of H-RQOL after adjustment for possible confounders. The presence of any chronic disease was associated with a decrease in the domain of vitality. The analysis of each individual chronic disease category revealed that no category was associated with a decrease in more than one domain of H-RQOL.

CONCLUSION

Loss of interest and depressed mood were associated with significant decreases in H-RQOL. We recommend these simple tests for screening in general practice.

Mental health and HIV sexual risk behavior among patrons of alcohol serving venues in Cape Town, South Africa

BACKGROUND

Alcohol-serving venues in South Africa provide a location for HIV prevention interventions due to risk factors of patrons in these establishments. Understanding the association between mental health and risk behaviors in these settings may inform interventions that address alcohol use and HIV prevention.

METHODS

Participants (n = 738) were surveyed in 6 alcohol-serving venues in Cape Town to assess post-traumatic stress disorder (PTSD) and depression symptoms, traumatic experiences, sexual behavior, and substance use. Logistic regression models examined whether traumatic experiences predicted PTSD and depression. Generalized linear models examined whether substance use, PTSD, and depressive symptoms predicted unprotected sexual intercourse. Men and women were analyzed separately.

RESULTS

Participants exhibited high rates of traumatic experiences, PTSD, depression, alcohol consumption, and HIV risk behaviors. For men, PTSD was associated with being hit by a sex partner, physical child abuse, sexual child abuse and HIV diagnosis; depression was associated with being hit by a sex partner, forced sex and physical child abuse. For women, both PTSD and depression were associated with being hit by a sex partner, forced sex, and physical child abuse. Unprotected sexual intercourse was associated with age, frequency and quantity of alcohol use, drug use, and PTSD for men and frequency and quantity of alcohol use, depression, and PTSD for women.

CONCLUSION

Mental health in this setting was poor and was associated with sexual risk behavior. Treating mental health and substance-use problems may aid in reducing HIV infection. Sexual assault prevention and treatment after sexual assault may strengthen HIV prevention efforts.

Depression, screening and quality of life in chronic kidney disease

INTRODUCTION

To determine the prevalence of positive screens for depression and to assess quality of life (QoL) and usefulness of the brief and easily administered Patient Health Questionnaire-2 (PHQ-2) for depression screening in the chronic kidney disease (CKD) population; and to explore the relationship between depressive symptoms and markers of inflammation.

METHODS

Seventy-one adult patients with estimated glomerular filtration rate <60 mL/min/1.73 m or proteinuria, but not on dialysis, were enrolled. QoL was assessed using the Short Form-36. The Center for Epidemiological Studies Depression Scale (CES-D) and PHQ-2 were used to screen for depression. Serum ferritin, albumin, C-reactive protein and hematocrit were also measured as markers of inflammation.

RESULTS

The PHQ-2 and CES-D were significantly correlated (P < 0.05). Positive scores on the CES-D or PHQ-2 had significantly lower Short Form-36 scores. Mean hemoglobin values were significantly lower in patients who screened positive for depression either by CES-D (12.2 ± 1.7 versus 13.2 ± 1.7, P < 0.05) or by PHQ-2 (12 ± 1.6 versus 13.4 ± 1.6, P < 0.01). Neither PHQ-2 nor CES-D correlated with other markers of inflammation in this sample.

CONCLUSION

Both the CES-D and the PHQ-2 can identify patients with CKD who need further evaluation for depression. The PHQ-2 seems to be a useful screen for depression and impaired QoL in a renal clinic setting. Patients with CKD and lower hemoglobin may be at greater risk for depression than those with normal values.

The 'help' question doesn't help when screening for major depression: external validation of the three-question screening test for primary care patients managed for physical complaints

BACKGROUND

Major depression, although frequent in primary care, is commonly hidden behind multiple physical complaints that are often the first and only reason for patient consultation. Major depression can be screened by two validated questions that are easier to use in primary care than the full Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. A third question, called the 'help' question, improves the specificity without apparently decreasing the sensitivity of this screening procedure. We validated the abbreviated screening procedure for major depression with and without the 'help' question in primary care patients managed for a physical complaint.

METHODS

This diagnostic accuracy study used data from the SODA (for 'SOmatisation Depression Anxiety') cohort study conducted by 24 general practitioners (GPs) in western Switzerland that included patients over 18 years of age with at least a single physical complaint at index consultation. Major depression was identified with the full Patient Health Questionnaire. GPs were asked to screen patients for major depression with the three screening questions 1 year after inclusion.

RESULTS

Of 937 patients with at least a single physical complaint, 751 were eligible 1 year after index consultation. Major depression was diagnosed in 69/724 (9.5%) patients. The sensitivity and specificity of the two-question method alone were 91.3% (95% CI 81.4 to 96.4) and 65.0% (95% CI 61.2 to 68.6), respectively. Adding the 'help' question decreased the sensitivity (59.4%; 95% CI 47.0 to 70.9) but improved the specificity (88.2%; 95% CI 85.4 to 90.5) of the three-question method.

CONCLUSIONS

The use of two screening questions for major depression was associated with high sensitivity and low specificity in primary care patients presenting a physical complaint. Adding the 'help' question improved the specificity but clearly decreased the sensitivity; when using the 'help' question, four out of ten patients with depression will be missed, compared to only one out of ten with the two-question method. Therefore, the 'help' question is not useful as a screening question, but may help discussing management strategies.

Depression screening and treatment among nonpregnant women of reproductive age in the United States, 1990-2010

INTRODUCTION

Whether routine screening for depression among nonpregnant women of reproductive age improves identification and treatment of the disorder remains unclear. We conducted a systematic review of the literature to address 5 key questions specific to this population: 1) What are the current national clinical practice recommendations and guidelines for depression screening; 2) What are the prevalence and predictors of screening; 3) How well do screening tools detect depression; 4) Does screening lead to diagnosis, treatment, and improved outcomes; and 5) What are the most effective treatment methods?

METHODS

We searched bibliographic databases for full-length articles published in English between 1990 and 2010 that addressed at least 1 of our key questions.

RESULTS

We identified 5 clinical practice guidelines pertinent to question 1, and 12 systematic reviews or post-hoc analyses of pooled data that addressed questions 3 through 5. No systematic reviews addressed question 2; however, we identified 4 individual studies addressing this question. Current guidelines do not recommend universal screening for depression in adults, unless staff supports are in place to diagnose, treat, and follow up patients. Reported screening rates ranged from 33% to 84% among women. Several validated screening tools for depression exist; however, their performance among this population is unknown. Screening in high-risk populations may improve the patient's receipt of diagnosis and treatment. Effective treatments include exercise, psychotherapy, and pharmacotherapy.

CONCLUSION

More research is needed on whether routine screening for depression among women of reproductive age increases diagnosis and treatment of depression, improves preconception health, and reduces adverse outcomes.

A randomised evaluation of CollAborative care and active surveillance for Screen-Positive EldeRs with sub-threshold depression (CASPER): study protocol for a randomized controlled trial

Background

Depression accounts for the greatest burden of disease among all mental health problems, and is expected to become the second-highest amongst all general health problems by 2020. By the age of 75, 1 in 7 older people meet formal diagnostic criteria for depression. Efforts to ameliorate the burden of illness and personal suffering associated with depression in older people have focussed on those with more severe depressive syndromes. Less attention has been paid to those with mild disorders/sub-threshold depressive syndromes but these patients also suffer impairments in their quality of life and level of functioning.

Methods/Design

The CASPER study has been designed to assemble an epidemiological cohort of people over 75 years of age (the CASPER cohort), from which we will identify those eligible to participate in a trial of collaborative care for sub-threshold depression (the CASPER trial).

We aim to undertake a pragmatic randomised controlled multi-centre trial evaluating the effectiveness and cost-effectiveness of collaborative care; a low intensity psychological intervention in addition to usual general practitioner care versus usual general practitioner care alone. General practitioners from practices based in the North of England will be asked to identify potentially eligible patients over the age of 75 years. Patients will be sent a letter inviting them to participate in the study.

We aim to recruit approximately 540 participants for the CASPER trial. A diagnostic interview will be carried out to ascertain trial eligibility with the major depressive episode module of the Mini International Neuropsychiatric Interview (M.I.N.I.), eligible participants randomised to either the intervention or usual care. The primary outcome will be measured with the Patient Health Questionnaire-9 (PHQ-9) and additional quality of life measures will be collected. Data will be collected at baseline, 4 and 12 months for both trial and cohort participants.

Validity of two case finding questions to detect postnatal depression: a review of diagnostic test accuracy

BACKGROUND

Postnatal depression (PND) is a serious condition associated with negative consequences for the wellbeing of mother and infant. In the UK routine screening for PND is not currently recommended, although the use of two case finding questions in routine practice to identify PND has been advocated in policy guidance. The diagnostic test accuracy (DTA) of the two questions has been reviewed in general population samples; however a review of their validity in postnatal populations is unknown. The aim of this rapid review was to identify studies of DTA of two case finding questions (2CFQ) for PND detection.

METHODS

DTA studies were included which compared the 2CFQ to gold standard diagnostic criteria. Sources searched included Medline, PsychInfo, Medion, ARIF and cited reference search via Web of Science.

RESULTS

Seven studies were identified which used a two question instrument to detect PND. Only one study compared the 2CFQ to standardised diagnostic criteria in a USA postnatal population. The test reported 100% sensitivity and 62% specificity at 4 postnatal weeks. The test was excellent at 'ruling out' PND given a negative response to both questions. False positive rates were high indicating unnecessary follow-up for a substantial number of women.

CONCLUSION

The review found limited evidence for use of the 2CFQ approach to detect PND. Further primary research should be undertaken to assess the DTA of the 2CFQ approach recommended for use in UK postnatal populations; this will ultimately inform the utility of current UK policy guidance.

Impact of the QOF and the NICE guideline in the diagnosis and management of depression: a qualitative study

BACKGROUND

The National Institute for Health and clinical Excellence (NICE) depression guideline (2004) and the updated Quality and Outcomes Framework (QOF) (2006) in general practice have introduced the concepts of screening severity assessment, for example using the Patient Health Questionnaire 9 (PHQ-9), and 'stepped care' for depression.

AIM

To explore primary care practitioner perspectives on the clinical utility of the NICE guideline and the impact of the QOF on diagnosis and management of depression in routine practice.

DESIGN AND SETTING

Qualitative study using focus groups from four multidisciplinary practice teams with diverse populations in south Yorkshire.

METHOD

Four focus groups were conducted, using a topic guide and audiotaping. There were 38 participants: GPs, nurses, doctors in training, mental health workers, and a manager. Data analysis was iterative and thematic.

RESULTS

The NICE guideline, with its embedded principles of holism and evidence-based practice, was viewed positively but its impact was compromised by resource and practitioner barriers to implementation. The perceived imposition of the screening questions and severity assessments (PHQ-9) with no responsive training had required practitioners to work hard to minimise negative impacts on their work, for example: constantly adapting consultations to tick boxes; avoiding triggering open displays of distress without the time to offer appropriate care; positively managing how their patients were labelled. Further confusion was experienced around the evolving content of psychological interventions for depression.

CONCLUSION

Organisational barriers to the implementation of the NICE guideline and the limited scope of the QOF highlight the need for policy makers to work more effectively with the complex realities of general practice in order to systematically improve the quality and delivery of 'managed' care for depression.

Multivariate graphical methods provide an insightful way to formulate explanatory hypotheses from limited categorical data

OBJECTIVE

Graphical methods for generating explanatory hypotheses from limited categorical data are described and illustrated.

STUDY DESIGN AND SETTING

Univariate, bivariate, multivariate, and multiplicative graphical methods were applied to clinical data regarding very ill older persons. The data to which these methods were applied were limited as to their nature (e.g., nominal categorical data) or quality (e.g., data subject to measurement error and missing values). Such limitations make confirmatory inference problematic but might still allow for meaningful generation of new explanatory hypotheses in some cases.

RESULTS

A striking feature of the graphical results from this study's major illustrative application was that posttraumatic stress disorder (PTSD) after intensive care unit discharge occurred rarely and nearly always co-occurred with two or more other mental health conditions. These results suggest the explanatory hypothesis that PTSD in this context is less attributable to single traumatic causes than to acute illnesses contributing to a cascade of mental health decrements.

CONCLUSION

Illustrative applications of a sequence of graphical procedures yield more informative and less abstract representations of limited data than do descriptive statistics alone, and by doing so, they aid in the formulation of explanatory hypotheses.

Screening for postpartum depression in a pediatric emergency department

OBJECTIVE

The objective was to determine whether a 3-question version of the Edinburgh Postpartum Depression Scale (EPDS) performs as well as the full EPDS in screening for postpartum depression in a pediatric emergency department (PED).

METHODS

Mothers of infants younger than 6 months presenting to an urban PED were enrolled. After the PED encounter, mothers were asked about demographics, health problems, insurance status, social support, food and housing security, and 3 questions from the EPDS. Mothers then completed the full EPDS. The primary outcome was the score on the full EPDS. Agreement between the 3 questions and the full EPDS for screening positive was measured. Test performance characteristics for screening positive with the 3 questions were calculated. Logistic regression determined the association between sociodemographic characteristics and screening positive. Provider impression of maternal depressive symptoms was recorded.

RESULTS

Of 195 mothers enrolled, 23% screened positive using the EPDS; 34% screened positive using the 3 questions (κ = 0.74). Compared with the EPDS, sensitivity of the 3 questions was 100%. Number of children younger than 5 years at home and having food and housing concerns were associated with screening positive. Of 44 mothers who screened positive on the full EPDS, providers identified 14 (32%) as having depressive symptoms or possibly being depressed.

CONCLUSIONS

Three questions from the EPDS performed similarly to the full EPDS in screening for postpartum depressive symptoms in a PED. Future studies are needed to confirm these findings and examine whether screening improves maternal and child health outcomes and quality-of-life concerns.

Factors associated with inappropriate weight loss attempts by early adolescent girls in Japan

Attempting to lose weight by normal or underweight adolescent girls is a serious issue in many countries. It has been reported that the mode of attempted weight loss does not differ between normal weight and overweight girls. These inappropriate weight loss attempts (IWLA) by normal or underweight adolescent girls is associated with various health issues, but factors associated with IWLA have only been marginally elucidated. In this study, we applied a single multivariate regression analysis to clarify independent factors for IWLA. Study subjects were 134 pairs of early adolescent girls (aged 12-15) and their mothers. In addition to IWLA, many factors including height, weight, body image, perceived weight status, depressive symptoms, media influence and self-esteem were surveyed in both mothers and daughters and subjected to multivariate analysis. Approximately half of girls surveyed had IWLA, even though all were of normal weight and 62.9% knew that they were of normal weight. IWLA were independently associated with depressive symptoms (OR (95% CI); 2.80 (1.21-6.50), p=0.016) independent of actual or perceived weight status. Factors significantly associated with IWLA by the girls were percentage deviation of weight from standard weight (%DW) and media influence on the girls themselves, and media influence on and self-esteem of their mothers. IWLA, which were frequently observed among early adolescent girls even among those of normal weight, were closely related to depressive status. IWLA were significantly associated with not only factors related to the girls (1.09 (1.04-1.14), p=0.001), but also with maternal psychological factors (1.06 (1.00-1.13), p=0.035) conveyed by the media. Future prospective or interventional studies are required to clarify whether these factors could be targeted in an effort to prevent IWLA.

How do the PHQ-2, the PHQ-9 perform in aging services clients with cognitive impairment?

OBJECTIVE

To examine the performance of the Patient Health Questionnaire-2 (PHQ-2) and the PHQ-9 in detecting current major depressive episode (MDE) in aging services care management clients who screen positive for cognitive impairment (CI).

METHODS

Cross-sectional observational study of 236 care management clients ages ≥60 years recruited from an Upstate NY aging services agency. The test characteristics of the PHQ-2 and PHQ-9 to screen for depression were calculated using the Structured Clinical Interview for DSM-IV (SCID) to identify MDE (gold standard). CI was identified with the Six-Item Screen (SIS).

RESULTS

Participants had a mean age of 77 years, 68% female, 16% non-white, and 26% had less than a high school education. 16% of participants had CI identified by ≥2 errors on SIS. Of these, 41% had positive PHQ-2 (scores ≥3), 43% had positive PHQ-9 (scores ≥10), while 24% met criteria for MDE. In the sample with CI, the PHQ-2, using a cutoff of 3, had sensitivity = 0.78, specificity = 0.71, and receiver operating characteristic (ROC) area under the curve (AUC) = 0.81, compared with 0.79, 0.82, and 0.88, respectively, for those without CI. In the sample with CI, the PHQ-9, using a cutoff of 10, had sensitivity = 0.89, specificity = 0.71, and AUC = 0.85, compared with 0.85, 0.89, and 0.91, respectively, for those without CI.

CONCLUSIONS

Cognitive status should be considered when using the PHQ as a depression screener due to poorer specificity in seniors with CI.
