Screening and case finding instruments for depression

Workplace mental health screening: a systematic review and meta-analysis

Workplaces are an important location for population mental health interventions. Screening to detect employees at risk of or experiencing mental ill health is increasingly common. This systematic review and meta-analysis examined the efficacy of workplace mental health screening programmes on employee mental health, work outcomes, user satisfaction, positive mental health, quality of life, help-seeking and adverse effects. PubMed, PsycINFO, EMBASE, CENTRAL, Global Index Medicus, Global Health and SciELO were searched (database inception-10 November 2022) and results screened by two independent reviewers. Controlled trials evaluating screening of workers' mental health as related to their employment were included. Random effects meta-analysis was performed to calculate pooled effect sizes for each outcome of interest. Grading of Recommendations Assessment, Development and Evaluation was conducted to evaluate the certainty of findings. Of the 12 328 records screened, 11 were included. These reported 8 independent trials collectively assessing 2940 employees. Results indicated screening followed by advice or referral was ineffective in improving employee mental health symptoms (n=3; d=-0.07 (95% CI -0.29 to 0.15)). Screening followed by facilitated access to treatment interventions demonstrated a small improvement in mental health (n=4; d=-0.22 (95% CI -0.42 to -0.02)). Limited effects were observed for other outcomes. Certainty ranged from low to very low. The evidence supporting workplace mental health screening programmes is limited and available data suggest mental health screening alone does not improve worker mental health. Substantial variation in the implementation of screening was observed. Further research disentangling the independent effect of screening alongside the efficacy of other interventions to prevent mental ill health at work is required.

Screening for Major Depressive Disorder Using a Wearable Ultra-Short-Term HRV Monitor and Signal Quality Indices

To encourage potential major depressive disorder (MDD) patients to attend diagnostic sessions, we developed a novel MDD screening system based on sleep-induced autonomic nervous responses. The proposed method only requires a wristwatch device to be worn for 24 h. We evaluated heart rate variability (HRV) via wrist photoplethysmography (PPG). However, previous studies have indicated that HRV measurements obtained using wearable devices are susceptible to motion artifacts. We propose a novel method to improve screening accuracy by removing unreliable HRV data (identified on the basis of signal quality indices (SQIs) obtained by PPG sensors). The proposed algorithm enables real-time calculation of signal quality indices in the frequency domain (SQI-FD). A clinical study conducted at Maynds Tower Mental Clinic enrolled 40 MDD patients (mean age, 37.5 ± 8.8 years) diagnosed on the basis of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and 29 healthy volunteers (mean age, 31.9 ± 13.0 years). Acceleration data were used to identify sleep states, and a linear classification model was trained and tested using HRV and pulse rate data. Ten-fold cross-validation showed a sensitivity of 87.3% (80.3% without SQI-FD data) and specificity of 84.0% (73.3% without SQI-FD data). Thus, SQI-FD drastically improved sensitivity and specificity.

Translating measurement into practice: Brazilian norms for the Patient Health Questionnaire (PHQ-9) for assessing depressive symptoms

OBJECTIVE

To provide practical norms for measuring depressive symptoms using the Patient Health Questionnaire 9 (PHQ-9) in Brazil using a state-of-art psychometrics analysis.

METHODS

We used a large and representative Brazilian dataset from the 'Pesquisa Nacional de Saúde - 2019'(PNS-2019), which includes 90,846 Brazilian citizens. First, to assess the scale structure, we assessed the unidimensional model using Confirmatory Factor Analysis (CFA). Second, we used Item Response Theory (IRT) to characterize depressive symptoms´ distribution. Then, we linked summed- and meanbased PHQ-9 scores with the IRT-based score by using generalized additive models. Finally, we generated percentiles, T scores, and a newly developed score, called D scores (decimal scores), to describe the PHQ-9 norms for Brazilian population.

RESULTS

CFA revealed a good fit to the unidimensional model, showing to be invariant to age and sex. IRT captured item-level information of the latent trait (reliable from 1 to 3 standard deviations above the mean). Brazilian norms were presented using summed-, T-scores, and D-scores.

CONCLUSIONS

This is the first study to define Brazilian´s norms for the PHQ-9 among a large representative sample, using robust psychometric tools. More precise PHQ-9 scores are now available and may be widely used in primary and specialized clinical care settings.

Edinburgh Postnatal Depression Scale used in South Korea

Background: The Edinburgh Postnatal Depression Scale (EPDS), a validated screening tool for prenatal and postnatal depression, was included as a reimbursable item by the National Health Insurance Service of Korea in 2020. However, multiple Korean versions of the EPDS are used for public health programs and research. This study aimed to summarize the use of this scale in Korea and evaluate the distribution of validities, depression scores, and prevalence of depression according to Korean versions of the EPDS.Methods: Korean versions of the EPDS most frequently used in public health policies and programs were summarized through internet searches using snowball strategy. A systematic literature review was conducted to evaluate the prenatal and postnatal depression scores and prevalence of depression measured using different Korean versions of the scale.Results: We identified four Korean versions of the EPDS that are commonly used in public health programs and research. Among them, published evidence regarding validity and reliability was available for two versions. A review of 19 papers that assessed prenatal and postnatal depression using these versions showed large heterogeneity in scores and the prevalence of depression.Conclusion: When measuring prenatal and postnatal depression using the EPDS, characteristics of the scale must be considered when interpreting results. A standardized Korean version of the EPDS needs to be developed by comparing the validity and reliability of different Korean versions. A field manual for screening should also be developed and distributed.

Improving the precision of depression diagnosis in general practice: a cluster-randomized trial

BACKGROUND

Methods to enhance the accuracy of the depression diagnosis continues to be of relevance to clinicians. The primary aim of this study was to compare the diagnostic precision of two different diagnostic strategies using the Mini International Neuropsychiatric Interview (MINI) as a reference standard. A secondary aim was to evaluate accordance between depression severity found via MINI and mean Major Depression Inventory (MDI) sum-scores presented at referral.

METHODS

This study was a two-armed, cluster-randomized superiority trial embedded in the Collabri trials investigating collaborative care in Danish general practices. GPs performing case-finding were instructed always to use MDI when suspecting depression. GPs performing usual clinical assessment were instructed to detect depression as they would normally do. According to guidelines, GPs would use MDI if they had a clinical suspicion, and patients responded positively to two or three core symptoms of depression. We compared the positive predictive value (PPV) in the two groups.

RESULTS

Fifty-one GP clusters were randomized. In total, 244 participants were recruited in the case-finding group from a total of 19 GP clusters, and 256 participants were recruited in the usual clinical assessment group from a total of 19 GP clusters. The PPV of the GP diagnosis, when based on case-finding, was 0.83 (95% CI 0.78-0.88) and 0.93 (95% CI 0.89-0.96) when based on usual clinical assessment. The mean MDI sum-scores for each depression severity group indicated higher scores than suggested cut-offs.

CONCLUSIONS

In this trial, systematic use of MDI on clinical suspicion of depression did not improve the diagnostic precision compared with the usual clinical assessment of depression.

The trial was retrospectively registered on 07/02/2016 at ClinicalTrials.gov. No. NCT02678845 .

Accuracy of Self-Reported Items for the Screening of Depression in the General Population

INTRODUCTION

Though self-reported items (SRD, self-reported depression) are commonly used in health surveys and cohort studies, their metric properties as a depression indicator remain unclear. The aims were to evaluate the measurement properties of SRD using the Patient Health Questionnaire-8 (PHQ-8) as reference and to identify factors related to the agreement between both indicators.

METHODS

Data from the European Health Interview Survey in Spain in 2014/2015 (n = 22,065) were analyzed. Two indicators of depression were considered: SRD based on two items yes/no (positive: both yes), and the PHQ-8 (positive ≥ 10). Socioeconomic factors and use of health services were considered as independent variables. The prevalence of depression, sensitivity, specificity, global agreement, and positive and negative predictive values (PPV and NPV) of SRDs were evaluated using the PHQ-8 as a reference. Logistic regression models were fitted to determine factors associated with the agreement between indicators.

RESULTS

The prevalence of depression was lower when assessed with PHQ-8 (5.9%) than with SRD (7.7%). SRD sensitivity and PPV were moderate-low (52.9% and 40.4%, respectively) whereas global agreement, specificity, and NPV were high (92.7%, 95.1%, and 97.0%, respectively). Positive agreement was associated with marital status, country of birth, employment status, and social class. Negative agreement was related to all independent variables except country of birth.

CONCLUSIONS

SRD items tend to overestimate the current prevalence of depression. While its use in health surveys and cohorts may be appropriate as a quick assessment of possible depression, due to their low sensitivity, its use in clinical contexts is questionable.

Depression and experience of incarceration in North Central Nigeria: a situation analysis at Makurdi medium security prison

Background

Human rights watchdogs have described conditions in Nigerian correctional facilities and detention centers as damaging to the physical and mental health of inmates. While the prevalence of mental disorders is high, access to appropriate healthcare is grossly inadequate. Understanding the current state of prison inmates’ mental health and well-being is an essential first step to addressing this important issue. This study aims to document the mental health and experiences of incarceration of inmates of the largest medium security prison in Nigeria’s Benue State.

Methods

A cross-sectional survey and descriptive analysis was carried out with a random sample of 381 prison inmates of Benue State Makurdi Medium Security Prison. Survey tools included: (1) a structured questionnaire on participants’ experiences in prison, and (2) the Patient Health Questionnaire (PHQ-9), a screening tool for depression.

Results

Most participants were young men (95.5%, mean age 27.95) and had completed secondary school (63.5%). While prison authorities had identified only 27 participants as having a mental disorder, 144 (37.8%) screened positive for depression. Twenty six had received professional counseling while in prison. Of the six participants who were already taking a psychotropic medication at the time of imprisonment, four received medication after being imprisoned. Approximately half, (52%) of participants were dissatisfied with prison health care.

Conclusions

Despite the high prevalence of depression among prison inmates, few cases are detected and treated. Prison staff may not recognize depression as a mental disorder, and the mental health care available is generally poor. Inadequate mental health and social care not only affects prison inmates’ well-being, but may also impact recidivism and health outcomes upon release. Prison inmates should be screened routinely for depression and other less-commonly recognized mental health conditions, and appropriate treatment made available.

Improving depression outcomes among Australian primary care patients: protocol for a cluster randomised controlled trial

INTRODUCTION

Depression is a common and debilitating condition. In Australia, general practitioners (GPs) are the key providers of depression care. However, available evidence suggests that case finding for depression in primary care is poor. This study will examine whether a systematic approach to screening for depression and assessing patient preferences for depression care improves depression outcomes among primary care patients.

METHODS AND ANALYSIS

A cluster randomised controlled design will be used with general practice clinics randomly assigned to either the intervention (n=12) or usual care group (n=12). Patients who are aged 18 and older, presenting for general practice care, will be eligible to participate. Eighty-three participants will be recruited at each clinic. Participants will be asked to complete a baseline survey administered on a touch screen computer at their GP clinic, and then a follow-up survey at 3, 6 and 12 months. Those attending usual care practices will receive standard care. GPs at intervention practices will complete an online Clinical e-Audit, and will be provided with provider and patient-directed resources for depression care. Patients recruited at intervention practices who score 10 or above on the Patient Health Questionnaire-9 will have feedback regarding their depression screening results and preferences for care provided to their GP. The primary analysis will compare the number of cases of depression between the intervention and control groups.

ETHICS AND DISSEMINATION

The study has been approved by the University of Newcastle Human Research Ethics Committee, and registered with Human Research Ethics Committees of the University of Wollongong, Monash University and University of New South Wales. Results will be disseminated through peer-reviewed journal publications and conference presentations.

Medical student depression and its correlates across three international medical schools

BACKGROUND

Medical students have high rates of depression, anxiety, and burnout that have been found to affect their empathy, professional behaviors, and performance as a physician. While studies have examined predictors for burnout and depression in the United States (US), no study, to our knowledge, has compared depression in medical students cross-culturally, or has attempted to examine the effect of factors influencing rates including burnout, exercise, stress, unmet mental health needs, and region.

AIM

To examine rates of depression in three international cohorts of medical students, and determine variables that may explain these differences.

METHODS

Convenience samples of medical students from three countries (US, China, and a Middle Eastern country whose name remains anonymous per request from the school) were surveyed in this observational study. Using the Patient Health Questionnaire-2 (PHQ-2) and a modified Maslach Burnout Inventory, depression and burnout were examined among medical students from the three cohorts (n = 473). Chi-square test and analysis of variance were used to examine differences in demographics, behavioral, and psychological variables across these three schools to identify potentially confounding descriptive characteristics. Analysis of covariance compared depression and the emotional exhaustion component of burnout identified through Principal Component Analysis across countries. Multiple linear regression was used to analyze the impact of demographic, behavioral, and psychological variables on screening positive for depression.

RESULTS

Medical students from the Middle Eastern country had the highest rates of positive depression screens (41.1%), defined as a PHQ-2 score of ≥ 3, followed by China (14.1 %), and then the US (3.8%). More students in the Middle Eastern school had unmet mental health needs (50.8%) than at the medical school in China (34.8%) or the school in the US (32.8%) (Pearson chi-square significance < 0.05). Thus, PHQ-2 scores were adjusted for unmet mental health needs; however, the Middle Eastern country continued to have the highest depression. Adjusting for PHQ-2 score, medical students from the US scored the highest on emotional exhaustion (a measure of burnout). Demographic variables did not significantly predict medical student depression; however, lack of exercise, unmet mental health needs, stress, and emotional exhaustion predicted nearly half of depression in these cohorts. In comparison to the US, coming from the Middle Eastern country and China predicted higher levels of depression.

CONCLUSION

Depression rates differ in three international cohorts of medical students. Measured factors contributed to some observed differences. Identifying site-specific prevention and intervention strategies in medical student mental health is warranted.

Optimal primary care management of clinical osteoarthritis and joint pain in older people: a mixed-methods programme of systematic reviews, observational and qualitative studies, and randomised controlled trials

Background

Osteoarthritis (OA) is the most common long-term condition managed in UK general practice. However, care is suboptimal despite evidence that primary care and community-based interventions can reduce OA pain and disability.

Objectives

The overall aim was to improve primary care management of OA and the health of patients with OA. Four parallel linked workstreams aimed to (1) develop a health economic decision model for estimating the potential for cost-effective delivery of primary care OA interventions to improve population health, (2) develop and evaluate new health-care models for delivery of core treatments and support for self-management among primary care consulters with OA, and to investigate prioritisation and implementation of OA care among the public, patients, doctors, health-care professionals and NHS trusts, (3) determine the effectiveness of strategies to optimise specific components of core OA treatment using the example of exercise and (4) investigate the effect of interventions to tackle barriers to core OA treatment, using the example of comorbid anxiety and depression in persons with OA.

Data sources

The North Staffordshire Osteoarthritis Project database, held by Keele University, was the source of data for secondary analyses in workstream 1.

Methods

Workstream 1 used meta-analysis and synthesis of published evidence about effectiveness of primary care treatments, combined with secondary analysis of existing longitudinal population-based cohort data, to identify predictors of poor long-term outcome (prognostic factors) and design a health economic decision model to estimate cost-effectiveness of different hypothetical strategies for implementing optimal primary care for patients with OA. Workstream 2 used mixed methods to (1) develop and test a ‘model OA consultation’ for primary care health-care professionals (qualitative interviews, consensus, training and evaluation) and (2) evaluate the combined effect of a computerised ‘pop-up’ guideline for general practitioners (GPs) in the consultation and implementing the model OA consultation on practice and patient outcomes (parallel group intervention study). Workstream 3 developed and investigated in a randomised controlled trial (RCT) how to optimise the effect of exercise in persons with knee OA by tailoring it to the individual and improving adherence. Workstream 4 developed and investigated in a cluster RCT the extent to which screening patients for comorbid anxiety and depression can improve OA outcomes. Public and patient involvement included proposal development, project steering and analysis. An OA forum involved public, patient, health professional, social care and researcher representatives to debate the results and formulate proposals for wider implementation and dissemination.

Results

This programme provides evidence (1) that economic modelling can be used in OA to extrapolate findings of cost-effectiveness beyond the short-term outcomes of clinical trials, (2) about ways of implementing support for self-management and models of optimal primary care informed by National Institute for Health and Care Excellence recommendations, including the beneficial effects of training in a model OA consultation on GP behaviour and of pop-up screens in GP consultations on the quality of prescribing, (3) against adding enhanced interventions to current effective physiotherapy-led exercise for knee OA and (4) against screening for anxiety and depression in patients with musculoskeletal pain as an addition to current best practice for OA.

Conclusions

Implementation of evidence-based care for patients with OA is feasible in general practice and has an immediate impact on improving the quality of care delivered to patients. However, improved levels of quality of care, changes to current best practice physiotherapy and successful introduction of psychological screening, as achieved by this programme, did not substantially reduce patients’ pain and disability. This poses important challenges for clinical practice and OA research.

Limitations

The key limitation in this work is the lack of improvement in patient-reported pain and disability despite clear evidence of enhanced delivery of evidence-based care.

Future work recommendations

(1) New thinking and research is needed into the achievable and desirable long-term goals of care for people with OA, (2) continuing investigation into the resources needed to properly implement clinical guidelines for management of OA as a long-term condition, such as regular monitoring to maintain exercise and physical activity and (3) new research to identify subgroups of patients with OA as a basis for stratified primary care including (i) those with good prognosis who can self-manage with minimal investigation or specialist treatment, (ii) those who will respond to, and benefit from, specific interventions in primary care, such as physiotherapy-led exercise, and (iii) develop research into effective identification and treatment of clinically important anxiety and depression in patients with OA and into the effects of pain management on psychological outcomes in patients with OA.

Effects on work ability, job strain and quality of life of monitoring depression using a self-assessment instrument in recurrent general practitioner consultations: A randomized controlled study

BACKGROUND:

Depression reduces individuals’ function and work ability and is associated with both frequent and long-term sickness absence.

OBJECTIVE:

Investigate if monitoring of depression course using a self-assessment instrument in recurrent general practitioner (GP) consultations leads to improved work ability, decreased job strain, and quality of life among primary care patients.

METHODS:

Primary care patients n = 183, who worked. In addition to regular treatment (control group), intervention patients received evaluation and monitoring and used the MADRS-S depression scale during GP visit at baseline and at visits 4, 8, and 12 weeks. Work ability, quality of life and job strain were outcome measures.

RESULTS:

Depression symptoms decreased in all patients. Significantly steeper increase of WAI at 3 months in the intervention group. Social support was perceived high in a significantly higher frequency in intervention group compared to control group.

CONCLUSIONS:

Monitoring of depression course using a self-assessment instrument in recurrent GP consultations seems to lead to improved self-assessed work ability and increased high social support, but not to reduced job strain or increased quality of life compared to TAU. Future studies concerning rehabilitative efforts that seek to influence work ability probably also should include more active interventions at the workplace.

The psychometric properties of depression screening tools in primary healthcare settings: A systematic review

BACKGROUND

Consensus on a tool for depression screening among adults in primary healthcare (PHC) settings is lacking. This systematic review aimed to explore the psychometric properties of depression screening tools.

METHODS

A systematic literature search composed of four terms (screening AND psychometric AND depression AND primary healthcare) was conducted in PubMed, EMBASE, PsycINFO and MEDLINE, between January 1995 through October 2015. Studies that aimed to psychometrically test a depression screening tool among the general adult population in a PHC setting were included. Studies exploring the diagnostic properties of depression screening tools among specific populations were excluded.

RESULTS

Sixty publications, evaluating the psychometric properties of 55 tools or adaptations, were included. Studies were conducted in 24 countries and 18 languages on 48234 adults. The Patient Health Questionnaire-9 was the most evaluated tool with 14 studies evaluating its psychometric properties. Fifty-four studies reported on at least one measure of receiver operating characteristics. Sensitivity and specificity values ranged from 28% to 100% and 43% to 100%, respectively. Cronbach alpha values ranged from 0.56 to 0.94. Other forms of reliability and validity testing were less consistently and commonly reported.

LIMITATIONS

The inclusion of studies regardless of methodological quality or design may have limited generalizability, but allowed for a comprehensive and detailed overview of the current literature.

CONCLUSIONS

Depression screening tools vary in their psychometric properties. The PHQ-9 was the most extensively psychometrically tested tool. This systematic review may aid PHC professionals in choosing a depression screening tool for universal use as it provides a comprehensive overview of their psychometric properties.

Depression comorbidity in migraine

Migraine and Major Depressive Disorder (MDD) are highly prevalent conditions that can lead to significant disability. These conditions are often comorbid, and several studies shed light on the underlying reasons for this comorbidity. The purpose of this review article is to have a closer look at the epidemiology, pathophysiology, genetic and environmental factors, temporal association, treatment options, and prognosis of patients suffering from both conditions, to allow a better understanding of what factors underlie this comorbidity. Studies show that patients with migraine are 2-4-times more likely to develop lifetime MDD, predominantly due to similar underlying pathophysiologic and genetic mechanisms. There appears to be a bidirectional temporal association between the two conditions, although longitudinal studies are needed to determine this more definitively. Quality-of-life and health-related outcomes are worse for patients that suffer from both conditions. Thus, a careful assessment of the patient with access to appropriate resources and follow-up is paramount. Future studies in genetics and brain imaging will be helpful in further elucidating the underlying mechanisms in these comorbid conditions, which will hopefully lead to better treatment options.

The prevalence of depression and the accuracy of depression screening tools in migraine patients

OBJECTIVES

Migraine and depression are common comorbid conditions. The purpose of this study was to assess how well the Patient Health Questionnaire (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS) perform as depression screening tools in patients with migraine.

METHODS

Three hundred consecutive migraine patients were recruited from a large headache center. The PHQ-9 and HADS were self-administered and validated against the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV, a gold standard for the diagnosis of depression. Sensitivity, specificity, positive predictive value, negative predictive value and receiver-operator characteristic curves were calculated for the PHQ-9 and HADS.

RESULTS

At the traditional cut-point of 10, the PHQ-9 demonstrated 82.0% sensitivity and 79.9% specificity. At a cut-point of 8, the HADS demonstrated 86.5% sensitivity and specificity. The PHQ-9 algorithm performed poorly (53.8% sensitivity, 94.9% specificity). The point prevalence of depression in this study was 25.0% (95% CI 19.0-31.0), and 17.0% of patients had untreated depression.

CONCLUSIONS

In this study, the PHQ-9 and HADS performed well in migraine patients attending a headache clinic, but optimal cut-points to screen for depression vary depending on the goals of the assessment. Also, migraine patients attending a headache clinic have a high prevalence of depression and many are inadequately treated. Future studies are needed to confirm these findings and to evaluate the impact of depression screening.

Collaborative care for depression in general practice: study protocol for a randomised controlled trial

BACKGROUND

Depression is a common illness with great human costs and a significant burden on the public economy. Previous studies have indicated that collaborative care (CC) has a positive effect on symptoms when provided to people with depression, but CC has not yet been applied in a Danish context. We therefore developed a model for CC (the Collabri model) to treat people with depression in general practice in Denmark. Since systematic identification of patients is an "active ingredient" in CC and some literature suggests case finding as the best alternative to standard detection, the two detection methods are examined as part of the study. The aim is to investigate if treatment according to the Collabri model has an effect on depression symptoms when provided to people with depression in general practice in Denmark, and to examine if case finding is a better method to detect depression in general practice than standard detection.

METHODS/DESIGN

The trial is a cluster-randomised, clinical superiority trial investigating the effect of treatment according to the Collabri model for CC, compared to treatment as usual for 480 participants diagnosed with depression in general practice in the Capital Region of Denmark. The primary outcome is depression symptoms (Beck's Depression Inventory (BDI-II)) after 6 months. Secondary outcomes include depression symptoms (BDI-II) after 15 months, anxiety symptoms (Beck's Anxiety Inventory (BAI)), level of functioning (Global Assessment of Function (GAF)) and psychological stress (Symptom Checklist-90-Revised (SCL-90-R)). In addition, case finding (with the recommended screening tool Major Depression Inventory (MDI)) and standard detection of depression is examined in a cluster-randomized controlled design. Here, the primary outcome is the positive predictive value of referral diagnosis.

DISCUSSION

If the Collabri model is shown to be superior to treatment as usual, the study will contribute with important knowledge on how to improve treatment of depression in general practice, with major benefit to patients and society. If case finding is shown to be superior to standard detection, it will be recommended as the detection method in future treatment according to the Collabri model.

Patient Health Questionnaire-9 versus Edinburgh Postnatal Depression Scale in screening for major depressive episodes: a cross-sectional population-based study

Background

Major depressive episodes (MDE) are frequent at the population level and are generally associated with severe symptoms that impair performance of activities of daily living of individuals suffering from this condition. The aim of this study was to compare the accuracy of two tests that separately showed suitable properties in screening for MDE: the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS).

Methods

In a previous study, the sensitivity and specificity of the PHQ-9 and the EPDS in screening for MDE were compared with a structured diagnostic interview conducted by psychiatrics and psychologists using the Mini International Neuropsychiatric Interview as the gold standard. In a sample of adults living in the community in Pelotas, Brazil, the PHQ-9 and EPDS were applied at the same interview and the gold standard on a median of 17 days later. The interviews were carried out at the participant’s home.

Results

447 Individuals (191 men and 256 women) were assessed. The PHQ-9 and the EPDS results were concordant in 87.5% of the respondents, with a moderate agreement beyond what was expected by chance alone (kappa = 0.61). The areas below the ROC curves were not statistically different (82.1% for PHQ-9 and 83.5% for EPDS) (p = 0.291), thus indicating that the two tests had similar moderate accuracy.

Conclusions

PHQ-9 and EPDS may be applied with equal confidence in screening for MDE in the community.

Strategies to improve anxiety and depression in patients with COPD: a mental health perspective

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by progressive and only partially reversible symptoms. Worldwide, the incidence of COPD presents a disturbing continuous increase. Anxiety and depression are remarkably common in COPD patients, but the evidence about optimal approaches for managing psychological comorbidities in COPD remains unclear and largely speculative. Pharmacological treatment based on selective serotonin reuptake inhibitors has almost replaced tricyclic antidepressants. The main psychological intervention is cognitive behavioral therapy. Of particular interest are pulmonary rehabilitation programs, which can reduce anxiety and depressive symptoms in these patients. Although the literature on treating anxiety and depression in patients with COPD is limited, we believe that it points to the implementation of personalized strategies to address their psychopathological comorbidities.

Online screening and feedback to increase help-seeking for mental health problems: population-based randomised controlled trial

BACKGROUND

Community-based screening for mental health problems may increase service use through feedback to individuals about their severity of symptoms and provision of contacts for appropriate services.

AIMS

The effect of symptom feedback on service use was assessed. Secondary outcomes included symptom change and study attrition.

METHOD

Using online recruitment, 2773 participants completed a comprehensive survey including screening for depression (n=1366) or social anxiety (n=1407). Across these two versions, approximately half (n=1342) of the participants were then randomly allocated to receive tailored feedback. Participants were reassessed after 3 months (Australian New Zealand Clinical Trials Registry ANZCTR12614000324617).

RESULTS

A negative effect of providing social anxiety feedback to individuals was observed, with significant reductions in professional service use. Greater attrition and lower intentions to seek help were also observed after feedback.

CONCLUSIONS

Online mental health screening with feedback is not effective for promoting professional service use. Alternative models of online screening require further investigation.

Symptoms of generalized anxiety disorder but not panic disorder at age 15 years increase the risk of depression at 18 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort study

BACKGROUND

Generalized anxiety disorder (GAD) and panic disorder (PD) differ in their biology and co-morbidities. We hypothesized that GAD but not PD symptoms at the age of 15 years are associated with depression diagnosis at 18 years.

METHOD

Using longitudinal data from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort we examined relationships of GAD and PD symptoms (measured by the Development and Well-Being Assessment) at 15 years with depression at 18 years (by the Clinical Interview Schedule - Revised) using logistic regression. We excluded adolescents already depressed at 15 years and adjusted for social class, maternal education, birth order, gender, alcohol intake and smoking. We repeated these analyses following multiple imputation for missing data.

RESULTS

In the sample with complete data (n = 2835), high and moderate GAD symptoms in adolescents not depressed at 15 years were associated with increased risk of depression at 18 years both in unadjusted analyses and adjusting for PD symptoms at 15 years and the above potential confounders. The adjusted odds ratio (OR) for depression at 18 years in adolescents with high relative to low GAD scores was 5.2 [95% confidence interval (CI) 3.0-9.1, overall p < 0.0001]. There were no associations between PD symptoms and depression at 18 years in any model (high relative to low PD scores, adjusted OR = 1.3, 95% CI 0.3-4.8, overall p = 0.737). Missing data imputation strengthened the relationship of GAD symptoms with depression (high relative to low GAD scores, OR = 6.2, 95% CI 3.9-9.9) but those for PD became weaker.

CONCLUSIONS

Symptoms of GAD but not PD at 15 years are associated with depression at 18 years. Clinicians should be aware that adolescents with GAD symptoms may develop depression.

Validity of brief screening questionnaires to detect depression in primary care in Ethiopia

BACKGROUND

Brief depression screening questionnaires may increase detection of depression in primary care settings but there have been few validation studies carried out in typical populations in low-income countries.

METHODS

Cultural validation of the Patient Health Questionnaire (PHQ-9/PHQ-2), the 20-item Self-Reporting Questionnaire (SRQ-20) and the Kessler scales (K6/K10) was carried out in 306 adults consecutively attending primary care facilities in small towns in Ethiopia. To assess criterion validity, the gold standard assessment for presence of Major Depressive Disorder (MDD) was made by Ethiopian psychiatric nurses using the Mini International Neuropsychiatric Interview.

RESULTS

The prevalence of gold standard MDD was 5.9%, with irritability more common than depressed mood or anhedonia. The area under the receiver operating characteristic curve indicated good performance of the PHQ-9, SRQ-20, K6 and K10 (0.83-0.85) but only fair for the PHQ-2 (0.78). No cut-off score had acceptable sensitivity combined with adequate positive predictive value. All screening questionnaires were associated with disability and the PHQ-9 and SRQ-20 were associated with higher health service contacts, indicating convergent validity. Construct validity of all scales was indicated by unidimensionality on exploratory factor analysis.

LIMITATIONS

Test-retest reliability was not assessed.

CONCLUSIONS

Brief depression screening questionnaires were found to be valid in primary care in this low-income country. However, these questionnaires do not have immediate applicability in routine clinical settings. Further studies should evaluate utility of indicated screening embedded within health system changes that support MDD detection. Investigation of irritability as a core depression symptom is warranted.

Screening for depression in older adults on an acute medical ward: the validity of NICE guidance in using two questions

BACKGROUND

depression is common in older people in general hospital settings and associated with poor outcomes. This study aimed to evaluate the validity of two screening questions recommended by the UK National Institute for Health and Clinical Excellence (NICE).

METHODS

one hundred and eighteen patients aged over 65 years, admitted to acute medical wards at a teaching hospital, were interviewed in a standardised manner using relevant sections of the Present State Examination-Schedules for Clinical Assessment in Neuropsychiatry to identify depression according to ICD-10 criteria. Subsequently, participants completed the two depression screening questions and the 15-item version of the Geriatric Depression Scale (GDS-15).

RESULTS

a threshold of one or more positive responses to the two NICE depression screening questions gave a sensitivity of 100%, specificity of 71%, positive predictive value (PPV) of 49% and negative predictive value (NPV) of 100%. The GDS-15 optimal cut-off was 6/7 with a sensitivity of 80%, specificity of 86%, PPV of 62% and NPV of 94%. A two-stage screening process utilising the NICE two questions followed by the GDS-15 with these cut-offs gave a sensitivity of 80%, specificity of 91%, PPV of 71% and NPV of 94%.

CONCLUSION

the two depression questions perform well as an initial screening process for non-cognitively impaired older people in the acute medical setting. A positive response to either question would indicate that further assessment is required by a clinician competent in diagnosing depression in this population, or the possible use of a more detailed instrument such as the GDS-15 to reduce the number of false-positive cases.

Evidence-based guidelines for treating depressive disorders with antidepressants: A revision of the 2008 British Association for Psychopharmacology guidelines

A revision of the 2008 British Association for Psychopharmacology evidence-based guidelines for treating depressive disorders with antidepressants was undertaken in order to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in September 2012. Key areas in treating depression were reviewed and the strength of evidence and clinical implications were considered. The guidelines were then revised after extensive feedback from participants and interested parties. A literature review is provided which identifies the quality of evidence upon which the recommendations are made. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse and stopping treatment. Significant changes since the last guidelines were published in 2008 include the availability of new antidepressant treatment options, improved evidence supporting certain augmentation strategies (drug and non-drug), management of potential long-term side effects, updated guidance for prescribing in elderly and adolescent populations and updated guidance for optimal prescribing. Suggestions for future research priorities are also made.

Health screening for older people-what are the current recommendations?

The world population of older people is on the rise with improved health services. With longevity, older people are at increased risk of chronic non-communicable diseases (NCDs), which are also leading causes of death among older people. Screening through case finding in primary care would allow early identification of NCDs and its risk factors, which could lead to the reduction of related complications as well as mortality. However, direct evidence for screening older people is lacking and the decision to screen for diseases should be made based on comorbidity, functional status and life expectancy, and has to be individualised.

Screening and treatment of psychological distress in patients with metastatic colorectal cancer: study protocol of the TES trial

Background/Introduction

Psychological distress occurs frequently in patients with cancer. Psychological distress includes mild and severe forms of both anxious and depressive mood states. Literature indicates that effective management of psychological distress seems to require targeted selection of patients (T), followed by enhanced care (E), and the application of evidence based interventions. Besides, it is hypothesized that delivering care according to the stepped care (S) approach results in an affordable program. The aim of the current study is to evaluate the (cost)-effectiveness of the TES program compared to usual care in reducing psychological distress in patients with metastatic colorectal cancer (mCRC).

Methods

This study is designed as a cluster randomized trial with 2 treatment arms: TES program for screening and treatment of psychological distress versus usual care. Sixteen hospitals participate in this study, recruiting patients with mCRC. Outcomes are evaluated at the beginning of chemotherapy and after 3, 10, 24, and 48 weeks. Primary outcome is the difference in treatment effect over time in psychological distress, assessed with the Hospital Anxiety and Depression Scale. Secondary outcomes include quality of life, patient evaluation of care, recognition and management of psychological distress, and societal costs.

Discussion

We created optimal conditions for an effective screening and treatment program for psychological distress in patients with mCRC. This involves targeted selection of patients, followed by enhanced and stepped care. Our approach will be thoroughly evaluated in this study. We expect that our results will contribute to the continuing debate on the (cost-) effectiveness of screening for and treatment of psychological distress in patients with cancer.

Office-based screening of common psychiatric conditions

Depression and anxiety disorders are common conditions with significant morbidity. Many screening tools of varying length have been well validated for these conditions in the office-based setting. Novel instruments, including Internet-based and computerized adaptive testing, may be promising tools in the future. The best evidence for cost-effectiveness currently is for screening of major depression linked with the collaborative care model for treatment. Data are not conclusive regarding comparative cost-effectiveness of screening for multiple conditions at once or for other conditions. This article reviews screening tools for depression and anxiety disorders in the ambulatory setting.

Screening for depression in the primary care population

Despite strong efforts, the diagnosis and treatment of depression bring many challenges in the primary care setting. Screening for depression has been shown to be effective only if reliable systems of care are in place to ensure appropriate treatment by clinicians and adherence by patients. New evidence-based models of care for depression exist, but spread has been slow because of inadequate funding structures and conflicts within current clinical culture. The Affordable Care Act introduces potential opportunities to reorganize funding structures, conceivably leading to increased adoption of these collaborative care models. Suicide screening remains controversial.

Integrated primary care for patients with mental and physical multimorbidity: cluster randomised controlled trial of collaborative care for patients with depression comorbid with diabetes or cardiovascular disease

OBJECTIVE

To test the effectiveness of an integrated collaborative care model for people with depression and long term physical conditions.

DESIGN

Cluster randomised controlled trial.

SETTING

36 general practices in the north west of England.

PARTICIPANTS

387 patients with a record of diabetes or heart disease, or both, who had depressive symptoms (≥ 10 on patient health questionaire-9 (PHQ-9)) for at least two weeks. Mean age was 58.5 (SD 11.7). Participants reported a mean of 6.2 (SD 3.0) long term conditions other than diabetes or heart disease; 240 (62%) were men; 360 (90%) completed the trial.

INTERVENTIONS

Collaborative care included patient preference for behavioural activation, cognitive restructuring, graded exposure, and/or lifestyle advice, management of drug treatment, and prevention of relapse. Up to eight sessions of psychological treatment were delivered by specially trained psychological wellbeing practitioners employed by Improving Access to Psychological Therapy services in the English National Health Service; integration of care was enhanced by two treatment sessions delivered jointly with the practice nurse. Usual care was standard clinical practice provided by general practitioners and practice nurses.

MAIN OUTCOME MEASURES

The primary outcome was reduction in symptoms of depression on the self reported symptom checklist-13 depression scale (SCL-D13) at four months after baseline assessment. Secondary outcomes included anxiety symptoms (generalised anxiety disorder 7), self management (health education impact questionnaire), disability (Sheehan disability scale), and global quality of life (WHOQOL-BREF).

RESULTS

19 general practices were randomised to collaborative care and 20 to usual care; three practices withdrew from the trial before patients were recruited. 191 patients were recruited from practices allocated to collaborative care, and 196 from practices allocated to usual care. After adjustment for baseline depression score, mean depressive scores were 0.23 SCL-D13 points lower (95% confidence interval -0.41 to -0.05) in the collaborative care arm, equal to an adjusted standardised effect size of 0.30. Patients in the intervention arm also reported being better self managers, rated their care as more patient centred, and were more satisfied with their care. There were no significant differences between groups in quality of life, disease specific quality of life, self efficacy, disability, and social support.

CONCLUSIONS

Collaborative care that incorporates brief low intensity psychological therapy delivered in partnership with practice nurses in primary care can reduce depression and improve self management of chronic disease in people with mental and physical multimorbidity. The size of the treatment effects were modest and were less than the prespecified effect but were achieved in a trial run in routine settings with a deprived population with high levels of mental and physical multimorbidity.

Factors associated with risk of depression and relevant predictors of screening for depression in clinical practice: a cross-sectional study among HIV-infected individuals in Denmark

OBJECTIVES

Depression and psychiatric disorders are frequent among HIV-infected individuals. The aim of this study was to determine the prevalence of depression and describe the psychiatric history of HIV-infected individuals in an out-patient clinic in Denmark and to identify factors of clinical importance that may be used to identify patients at risk of depression.

METHODS

In 2013, 212 HIV-infected patients were included in a questionnaire study. We used the Beck Depression Inventory II (BDI-II) to assess the prevalence and severity of depressive symptoms. Patients with a BDI-II score ≥ 20 were offered a clinical evaluation by a consultant psychiatrist. Logistic regression was used to determine predictors associated with risk of depression.

RESULTS

Symptoms of depression (BDI-II score ≥ 14) were observed in 75 patients (35%), and symptoms of moderate to major depression (BDI-II score ≥ 20) in 55 patients (26%). There was also a high prevalence of co-occurring mental illness. In a multivariate model, self-reported stress, self-reported perception that HIV infection affects all aspects of life, self-reported poor health, not being satisfied with one's current life situation, previous alcohol abuse, nonadherence to antiretroviral therapy and previously having sought help because of psychological problems were independently associated with risk of depression.

CONCLUSIONS

Symptoms of depression and co-occurring mental illness are under-diagnosed and under-treated among HIV-infected individuals. We recommend that screening of depression should be conducted regularly to provide a full psychiatric profile to decrease the risk of depression and improve adherence and quality of life in this population.

Individual counseling is the preferred treatment for depression in breast cancer survivors

A substantial number of cancer patients experience depression. This study investigated treatment preferences for depression. Breast cancer survivors (N = 134) completed an anonymous survey asking preference and interest in three treatments for depression: individual counseling (IC), antidepressant medication (MED), or support groups (SG). Participants were recruited from a surgical oncology office and asked to complete the survey as they waited for their appointment. Preference was compared using Wilcoxon Signed Ranks tests. More than 50% ranked IC as first choice of treatment. Preference for IC was significantly higher than preference for MED and SG. Preference between MED and SG did not differ. Survivors prefered counseling for treatment of depression. Cancer centers should be prepared to provide preferred treatment methods, particulary as screening, and therefore management, of psychosocial distress is to be required.

Anxiety and depression-Important psychological comorbidities of COPD

Anxiety and depression are common and important comorbidities in patients with chronic obstructive pulmonary disease (COPD). The pathophysiology of these psychological comorbidities in COPD is complex and possibly explained by common risk factors, response to symptomatology and biochemical alterations. The presence of anxiety and/or depression in COPD patients is associated with increased mortality, exacerbation rates, length of hospital stay, and decreased quality of life and functional status. There is currently no consensus on the most appropriate approach to screening for anxiety and depression in COPD. Treatment options include psychological [relaxation, cognitive behavioural therapy (CBT), self-management] and pharmacological interventions. Although there is some evidence to support these treatments in COPD, the data are limited and mainly comprised by small studies. Pulmonary rehabilitation improves anxiety and depression, and conversely these conditions impact rehabilitation completion rates. Additional high quality studies are urgently required to optimise screening and effective treatment of anxiety and depression in patients with COPD, to enhance complex chronic disease management for these patients.

Standardization of the Colombian version of the PHQ-4 in the general population

BACKGROUND

The PHQ-4 is a widely used open access screening instrument for depression and anxiety in different health care and community settings; however, empirical evidence of its psychometric quality in Colombia is lacking. The objectives of the current study were to generate normative data and to further investigate the construct validity and factorial structure of the PHQ-4 in the general population.

METHODS

A nationally representative face-to-face household survey was conducted in Colombia in 2012 (n = 1,500). The item characteristics of the PHQ-4 items, including the inter-item correlations and inter-subscale correlations, were investigated. To measure the scale's reliability, the internal consistency (Cronbach's α) was assessed. For factorial validity, the factor structure of the PHQ-4 was examined with confirmatory factor analysis (CFA).

RESULTS

The Cronbach's alpha coefficient for the PHQ-4 was 0.84. The confirmatory factor analysis supported a two-factor model, which was structurally invariant between different age and gender groups. Normative data for the PHQ-4 were generated for both genders and different age levels. Women had significantly higher mean scores compared with men [1.4 (SD: 2.1) vs. 1.1 (SD: 1.9), respectively]. The results supported the discriminant validity of the PHQ-4.

CONCLUSIONS

The normative data provide a framework for the interpretation and comparisons of the PHQ-4 with other populations in Colombia. The evidence supports the reliability and validity of the two-factor PHQ-4 as a measure of anxiety and depression in the general Colombian population.

Adult depression screening in Saudi primary care: prevalence, instrument and cost

BACKGROUND

By the year 2020 depression would be the second major cause of disability adjusted life years lost, as reported by the World Health Organization. Depression is a mental illness which causes persistent low mood, a sense of despair, and has multiple risk factors. Its prevalence in primary care varies between 15.3-22%, with global prevalence up to 13% and between 17-46% in Saudi Arabia. Despite several studies that have shown benefit of early diagnosis and cost-savings of up to 80%, physicians in primary care setting continue to miss out on 30-50% of depressed patients in their practices.

METHODS

A cross sectional study was conducted at three large primary care centers in Riyadh, Saudi Arabia aiming at estimating point prevalence of depression and screening cost among primary care adult patients, and comparing Patient Health Questionnaires PHQ-2 with PHQ-9. Adult individuals were screened using Arabic version of PHQ-2 and PHQ-9. PHQ-2 scores were correlated with PHQ-9 scores using linear regression. A limited cost-analysis and cost saving estimates of depression screening was done using the Human Capital approach.

RESULTS

Patients included in the survey analysis were 477, of whom 66.2% were females, 77.4% were married, and nearly 20% were illiterate. Patients exhibiting depressive symptoms on the basis of PHQ9 were 49.9%, of which 31% were mild, 13.4% moderate, 4.4% moderate-severe and 1.0% severe cases. Depression scores were significantly associated with female gender (p-value 0.049), and higher educational level (p-value 0.002). Regression analysis showed that PHQ-2 & PHQ-9 were strongly correlated R = 0.79, and R2 = 0.62. The cost-analysis showed savings of up to 500 SAR ($133) per adult patient screened once a year.

CONCLUSION

The point prevalence of screened depression is high in primary care visitors in Saudi Arabia. Gender and higher level of education were found to be significantly associated with screened depression. Majority of cases were mild to moderate, PHQ-2 was equivocal to PHQ 9 in utility and that screening for depression in primary care setting is cost saving.

An interprofessional nurse-led mental health promotion intervention for older home care clients with depressive symptoms

Background

Depressive symptoms in older home care clients are common but poorly recognized and treated, resulting in adverse health outcomes, premature institutionalization, and costly use of health services. The objectives of this study were to examine the feasibility and acceptability of a new six-month interprofessional (IP) nurse-led mental health promotion intervention, and to explore its effects on reducing depressive symptoms in older home care clients (≥ 70 years) using personal support services.

Methods

A prospective one-group pre-test/post-test study design was used. The intervention was a six-month evidence-based depression care management strategy led by a registered nurse that used an IP approach. Of 142 eligible consenting participants, 98 (69%) completed the six-month and 87 (61%) completed the one-year follow-up. Outcomes included depressive symptoms, anxiety, health-related quality of life (HRQoL), and the costs of use of all types of health services at baseline and six-month and one-year follow-up. An interpretive descriptive design was used to explore clients’, nurses’, and personal support workers’ perceptions about the intervention’s appropriateness, benefits, and barriers and facilitators to implementation.

Results

Of the 142 participants, 56% had clinically significant depressive symptoms, with 38% having moderate to severe symptoms. The intervention was feasible and acceptable to older home care clients with depressive symptoms. It was effective in reducing depressive symptoms and improving HRQoL at six-month follow-up, with small additional improvements six months after the intervention. The intervention also reduced anxiety at one year follow-up. Significant reductions were observed in the use of hospitalization, ambulance services, and emergency room visits over the study period.

Conclusions

Our findings provide initial evidence for the feasibility, acceptability, and sustained effects of the nurse-led mental health promotion intervention in improving client outcomes, reducing use of expensive health services, and improving clinical practice behaviours of home care providers. Future research should evaluate its efficacy using a randomized clinical trial design, in different settings, with an adequate sample of older home care recipients with depressive symptoms.

Asking women about mental health and social adversity in pregnancy: results of an Australian population-based survey

BACKGROUND

Social adversity undermines health in pregnancy. The objective of this study was to examine the extent to which pregnant women were asked about their mental health and life circumstances in pregnancy checkups.

METHOD

Population-based postal survey of recent mothers in two Australian states.

FINDINGS

Around half of the 4,366 participants reported being asked about depression (45.9%) and whether they were anxious or worried about things happening in their life (49.6%); fewer reported being asked about relationship issues (29.6%), financial problems (16.6%), or family violence (14.1%). One in five women (18%) reported significant social adversity. These women were more likely to recall being asked about their mental health and broader social health issues. Far higher levels of inquiry were reported by women in the public maternity system with midwives more likely than doctors to ask about mental health, family violence, and other social hardships.

CONCLUSIONS

Routine pregnancy visits afford a window of opportunity for identifying and supporting women experiencing mental health problems and social adversity. Changing practice to take advantage of this opportunity will require concerted and coordinated efforts by practitioners and policy makers to build systems to support public health approaches to antenatal care.

Tablet-based screening of depressive symptoms in quito, ecuador: efficiency in primary care

Depression is a frequent yet overlooked occurrence in primary health care clinics worldwide. Depression and related health screening instruments are available but are rarely used consistently. The availability of technologically based instruments in the assessments offers novel approaches for gathering, storing, and assessing data that includes self-reported symptom severity from the patients themselves as well as clinician recorded information. In a suburban primary health care clinic in Quito, Ecuador, we tested the feasibility and utility of computer tablet-based assessments to evaluate clinic attendees for depression symptoms with the goal of developing effective screening and monitoring tools in the primary care clinics. We assessed individuals using the 9-item Patient Health Questionnaire, the Quick Inventory of Depressive Symptoms-Self-Report, the 12-item General Health Questionnaire, the Clinical Global Impression Severity, and a DSM-IV checklist of symptoms. We found that 20% of individuals had a PHQ9 of 8 or greater. There was good correlation between the symptom severity assessments. We conclude that the tablet-based PHQ9 is an excellent and efficient method of screening for depression in attendees at primary health care clinics and that one in five people should be assessed further for depressive illness and possible intervention.

There are no randomized controlled trials that support the United States Preventive Services Task Force Guideline on screening for depression in primary care: a systematic review

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).

Equations for converting scores between depression scales (MÅDRS, SRS, PHQ-9 and BDI-II): good statistical, but weak idiographic, validity

BACKGROUND

A variety of depression rating scales are currently used in clinical and research practice. As these scales are generally thought to correlate well, there may be some benefit in deriving equations to translate the score on one scale to that on another.

METHOD

Using pairwise ratings, we compared the Montgomery-Åsberg Depression Rating Scale (MÅDRS), Beck Depression Inventory II (BDI-II), Patient Health Questionnaire (PHQ-9) and Zung Self Rated Scale (SRS). The primary comparisons of interest were as follows: PHQ-9 and MÅDRS, PHQ-9 and BDI-II, SRS and MÅDRS, and SRS and PHQ-9. One hundred and fifty pairs of ratings were collected for each of these four comparisons, and these were used in a regression analysis to generate a predictive equation between scale pairs. The predictive equations were then tested for accuracy by using novel data.

RESULTS

There was a reasonably strong correlation between scales. Simple regression equations describe the relationships between certain permutations of the BDI-II, PHQ-9, SRS and MÅDRS well enough to allow the score on one scale to be estimated from the score on another. On average, the equations work well. However, when used to predict individual cases, they often fail.

CONCLUSION

It does appear that conversion equations for depression scores are precise enough to be of use when applied to averages; these might aid comparison of data across different studies, meta-analysis or instrument selection for clinical trials. But regarding scale translation at the idiographic level, the variability we have observed is so great that severe doubt is cast on the validity of such an approach.

Universal mental health screening in pediatric primary care: a systematic review

OBJECTIVE

Universal mental health screening in pediatric primary care is recommended, but studies report slow uptake and low rates of patient follow-through after referral to specialized services. This review examined possible explanations related to the process of screening, focusing on how parents and youth are engaged, and how providers evaluate and use screening results.

METHOD

A narrative synthesis was developed after a systematic review of 3 databases (plus follow-up of citations, expert recommendations, and checks for multiple publications about the same study). Searching identified 1,188 titles, and of these, 186 full-text articles were reviewed. Two authors extracted data from 45 articles meeting inclusion criteria.

RESULTS

Published studies report few details about how mental health screens were administered, including how clinicians explain their purpose or confidentiality, or whether help was provided for language, literacy, or disability problems. Although they were not addressed directly in the studies reviewed, uptake and detection rates appeared to vary with means of administration. Screening framed as universal, confidential, and intended to optimize attention to patient concerns increased acceptability. Studies said little about how providers were taught to explore screen results. Screening increased referrals, but many still followed negative screens, in some cases because of parent concerns apparently not reflected by screen results but possibly stemming from screen-prompted discussions.

CONCLUSIONS

Little research has addressed the process of engaging patients in mental health screening in pediatric primary care or how clinicians can best use screening results. The literature does offer suggestions for better clinical practice and research that may lead to improvements in uptake and outcome.

Screening for depression: a systematic review and meta-analysis

BACKGROUND

The Canadian Task Force on Preventive Health Care has a guideline on screening for depression among adults 18 years of age or older at average or high risk for depression. To provide evidence for an update of this guideline, we evaluated the literature on the effectiveness of screening for depression in adults.

METHODS

For the period 1994 to May 23, 2012, we searched the following electronic databases: MEDLINE, Embase, PsycINFO, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews. Randomized controlled trials, observational studies and systematic reviews with evidence for the benefits or harms of screening for depression were eligible for inclusion. We performed screening for relevance, extraction of data, analysis of risk of bias and quality assessments in duplicate. We used the generic inverse variance method to conduct a meta-analysis. To determine confidence in the effect, we analyzed the results according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

RESULTS

Five quasi-experimental studies (before-after design with a nonrandomized control group) met the inclusion criteria for this review. These studies reported on the effect of community-based screening for depression, with follow-up on the risk of suicide completion, for older residents in regions of rural Japan with high suicide rates. Meta-analysis showed that the screening program had a protective effect on the overall incidence of suicide completion (ratio of rate ratios [RRR] 0.50, 95% confidence interval [CI], 0.32-0.78). When sex was considered, the RRR indicated a significantly lower rate of suicide among women (RRR 0.37, 95% CI 0.21-0.66) but not among men (RRR 0.67, 95% CI 0.35-1.27). The overall GRADE rating applied to this evidence indicated very low quality. No studies addressing the harms of screening for depression met the inclusion criteria for the review.

INTERPRETATION

There is very limited research evidence allowing conclusions about the effectiveness of screening for depression in either average-risk or high-risk populations.

Educating family physicians to recognize and manage depression: where are we now?

OBJECTIVES

To consider what the barriers are to effective depression education; to understand what attitudes, knowledge, and skills doctors need to acquire, and finally to examine what we currently know about effective ways of training family physicians (FPs) about depression.

METHODS

A narrative review of the published literature compiled from searching reviews and original articles was conducted using the following key words: education, training, attitudes, depression, and primary care. Further relevant articles were identified from reference lists.

RESULTS

The identified barriers are FPs' attitudes and confidence toward recognizing and managing depression, the way in which they conceptualize depression, and the difficulties they face in implementing change in the systems in which they work. We, as educators, can identify what FPs need to know, and this should include novel ways of organizing care. However, of key importance is the need to address how more effective interventions may be provided, recognizing that FPs may be starting from many different points on 3 differing continua of attitude, skills, and knowledge in relation to depression.

CONCLUSIONS

We have to not only ensure that the content of what we teach is perceived as relevant to primary care but also review exactly how we go about providing it, using methods that will engage and stimulate doctors at differing stages of readiness to acquire new attitudes, skills, and knowledge about depression. However, we still need to find better ways of helping FPs to recognize and acknowledge their educational needs. Further research is also required to thoroughly evaluate these novel approaches to tailoring educational interventions.

Depression in primary care: current and future challenges

OBJECTIVES

To describe the current state of knowledge about detection and treatment of major depressive disorder (MDD) by family physicians (FPs), and to identify gaps in practice and current and future challenges.

METHODS

We reviewed the recent literature on MDD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, or International Classification of Diseases, Revision 10) in primary care, with an emphasis on systematic reviews and meta-analyses addressing prevalence, the impact of an aging population and of chronic disease on MDD rates in primary care, detection and treatment rates by FPs, adequacy of treatment, and interventions that could improve recognition and treatment.

RESULTS

About 10% of primary care patients are likely to meet criteria for MDD. The number of cases will increase as the baby boomer cohort ages and as the prevalence of chronic disease increases. The bidirectional relation between MDD and chronic disease is now firmly established. Detection and treatment rates in primary care remain low. Treatment quality is frequently inadequate in terms of follow-up and monitoring. Formal case management and collaborative care interventions are likely to provide some benefits.

CONCLUSIONS

Low detection rates and low treatment rates need to be addressed. Planned reassessment may improve detection rates when the FP is uncertain whether MDD is present, but further research is needed to determine why FPs frequently do not initiate treatment, even when MDD is detected. A caring, attentive FP who monitors depressed patients is likely to have considerable placebo effect. Greater focus on integrated, concurrent treatment for MDD and chronic physical diseases in the middle-aged and elderly is also required.

Postpartum depression screening: initial implementation in a multispecialty practice with collaborative care managers

Postpartum depression (PPD) has emerged as an important issue for pediatricians and family practitioners because of detrimental effects on children. PPD occurs in 10% to 22% of women who have recently given birth, but fewer than half of cases are recognized. Despite the impact of PPD, many primary care clinicians do not have systemic screening approaches implemented. This paper will review the development of a screening protocol for PPD in a multispecialty clinic, with the implementation utilizing depression care managers and the preliminary results of our process. Of the 333 screened examinations during the 4-month study, 38.1% (n = 127) were performed for the 2-month well child examination; 33.6% (n = 112) were for the 4-month examination, with 28.2% (n = 94) being performed for the 6-month well child examination. Only 15 (4.5%) were positive for possible depression with a screening compliance rate of 47.9%. No significant difference was noted in the timing of the well child visit with a positive screening test result, nor was there any difference in family medicine versus pediatric colleagues in the utilization of the screening or diagnosis of PPD. Implementation of PPD screening in a multispecialty clinic can be effective, given utilization of depression care managers.

A qualitative study of primary care professionals' views of case finding for depression in patients with diabetes or coronary heart disease in the UK

BACKGROUND

Routinely conducting case finding (also commonly referred to as screening) in patients with chronic illness for depression in primary care appears to have little impact. We explored the views and experiences of primary care nurses, doctors and managers to understand how the implementation of case finding/screening might impact on its effectiveness.

METHODS

Two complementary qualitative focus group studies of primary care professionals including nurses, doctors and managers, in five primary care practices and five Community Health Partnerships, were conducted in Scotland.

RESULTS

We identified several features of the way case finding/screening was implemented that may lead to systematic under-detection of depression. These included obstacles to incorporating case finding/screening into a clinical review consultation; a perception of replacing individualised care with mechanistic assessment, and a disconnection for nurses between management of physical and mental health. Far from being a standardised process that encouraged detection of depression, participants described case finding/screening as being conducted in a way which biased it towards negative responses, and for nurses, it was an uncomfortable task for which they lacked the necessary skills to provide immediate support to patients at the time of diagnosis.

CONCLUSION

The introduction of case finding/screening for depression into routine chronic illness management is not straightforward. Routinized case finding/screening for depression can be implemented in ways that may be counterproductive to engagement (particularly by nurses), with the mental health needs of patients living with long term conditions. If case finding/screening or engagement with mental health problems is to be promoted, primary care nurses require more training to increase their confidence in raising and dealing with mental health issues and GPs and nurses need to work collectively to develop the relational work required to promote cognitive participation in case finding/screening.

Systematic depression screening in high-risk patients attending primary care: a pragmatic cluster-randomized trial

BACKGROUND

Systematic screening for depression in high-risk patients is recommended but remains controversial. The aim of this study was to assess the effectiveness of such screening in everyday clinical practice on depression recognition.

METHODS

A pragmatic, cluster randomized, controlled study that randomized primary care physicians (PCPs) in Spain either to an intervention or control group. The intervention group (35-PCPs) received training in depression screening and used depression screening routinely for at least 6 months. The control group (34-PCPs) managed depression in their usual manner. Adherence to (1-6; never-very frequently), feasibility (1-4; unfeasible-very feasible), and acceptance (1-5; very poor-very good) of the screening were evaluated. Underrecognition (primary outcome) and undertreatment rates of major depressive disorder (MDD) in the two groups were compared 6 months after randomization in a random sample of 3737 patients assigned to these PCPs using logistic regression adjusting for the clustering effect.

RESULTS

No significant differences were found for recognition rates (58.0% vs. 48.1% intervention vs. control; OR [95%CI] 1.40 [0.73-2.68], p = 0.309). The undertreatment rate did not differ significantly either (p = 0.390). The mean adherence to depression screening was 4.4 ± 1.0 ('occasionally'), the mean feasibility was 3.1 ± 0.5 ('moderately feasible'), and the mean acceptance was 4.2 ± 0.6 ('good').

CONCLUSIONS

This research was not able to show effectiveness of the systematic screening for MDD in high-risk patients on depression recognition in primary care. The poor adherence to screening implementation could partially explain the results. These reflect the difficulties of putting into practice the clinical guidelines usually based on interventional research.

Integrated care: treatment initiation following positive depression screens

BACKGROUND

Primary Care-Mental Health Integration (PC-MHI) may improve mental health services access and continuity of care.

OBJECTIVE

To assess whether receipt of integrated PC-MHI services on the date of an initial positive depression screen influences receipt of depression treatment among primary care (PC) patients in the Veterans Health Administration.

DESIGN

Retrospective cohort study.

SUBJECTS

Thirty-six thousand, two hundred and sixty-three PC patients with positive depression screens between October 1, 2009 and September 30, 2010.

MAIN MEASURES

Subjects were assessed for depression diagnosis and initiation of antidepressants or psychotherapy on the screening day, within 12 weeks, and within 6 months. Among individuals with PC encounters on the screening day, setting of services received that day was categorized as PC only, PC-MHI, or Specialty Mental Health (SMH). Using multivariable generalized estimating equations (GEE) logistic regression, we assessed likelihood of treatment initiation, adjusting for demographic and clinical measures, including depression screening score.

KEY RESULTS

Patients who received same-day PC-MHI services were more likely to initiate psychotherapy (OR: 8.16; 95 % CI: 6.54-10.17) and antidepressant medications (OR: 2.33, 95 % CI: 2.10-2.58) within 12 weeks than were those who received only PC services on the screening day.

CONCLUSIONS

Receipt of same-day PC-MHI may facilitate timely receipt of depression treatment.
