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

KDIGO clinical practice guideline for the care of kidney transplant recipients

The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline on the monitoring, management, and treatment of kidney transplant recipients is intended to assist the practitioner caring for adults and children after kidney transplantation. The guideline development process followed an evidence-based approach, and management recommendations are based on systematic reviews of relevant treatment trials. Critical appraisal of the quality of the evidence and the strength of recommendations followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach. The guideline makes recommendations for immunosuppression, graft monitoring, as well as prevention and treatment of infection, cardiovascular disease, malignancy, and other complications that are common in kidney transplant recipients, including hematological and bone disorders. Limitations of the evidence, especially on the lack of definitive clinical outcome trials, are discussed and suggestions are provided for future research.

Chronic neck pain following car crashes: a population-based study from Auckland, New Zealand

BACKGROUND

  In a setting with a 'no fault' universal government-funded accident compensation system, we undertook a study to (i) estimate the prevalence and predictors of chronic neck pain in car occupants surviving serious injury-producing crashes and (ii) compare the longer-term health-related quality of life of crash survivors with and without neck discomfort.

METHODS

  A prospective cohort study recruited hospitalized survivors aged ≥16 years and non-hospitalized drivers of cars involved in serious crashes in Auckland over a 10-month period. Participants completed a structured questionnaire at recruitment and 5 and 18 months later.

RESULTS

  Of the 268 participants, 50 (18.7%) reported neck pain or stiffness at 5 and 18 months following the crash. Of these, 70% noted the discomfort led to limitations in work and recreation. Depressive and post-traumatic stress symptoms at 5 months were associated with an increased risk of moderate to severe neck discomfort at 18 months. Participants with and without neck discomfort had significantly reduced health-related quality of life based on Short Form-36 scores.

CONCLUSION

  Significant neck discomfort limiting usual function is relatively common up to 18 months following crashes. The reductions in health status among crash survivors with and without neck pain reveal the complexities in attributing longer-term adverse outcomes to a particular condition in the absence of an appropriate comparison group. The findings indicate the need to manage judiciously comorbid conditions while prioritizing efforts to support crash survivors' return to their usual social roles and activities.

Screening for emotional distress in cancer patients: a systematic review of assessment instruments

Screening for emotional distress is becoming increasingly common in cancer care. This systematic review examines the psychometric properties of the existing tools used to screen patients for emotional distress, with the goal of encouraging screening programs to use standardized tools that have strong psychometrics. Systematic searches of MEDLINE and PsycINFO databases for English-language studies in cancer patients were performed using a uniform set of key words (eg, depression, anxiety, screening, validation, and scale), and the retrieved studies were independently evaluated by two reviewers. Evaluation criteria included the number of validation studies, the number of participants, generalizability, reliability, the quality of the criterion measure, sensitivity, and specificity. The literature search yielded 106 validation studies that described a total of 33 screening measures. Many generic and cancer-specific scales satisfied a fairly high threshold of quality in terms of their psychometric properties and generalizability. Among the ultrashort measures (ie, those containing one to four items), the Combined Depression Questions performed best in patients receiving palliative care. Among the short measures (ie, those containing five to 20 items), the Center for Epidemiologic Studies–Depression Scale and the Hospital Anxiety and Depression Scale demonstrated adequate psychometric properties. Among the long measures (ie, those containing 21–50 items), the Beck Depression Inventory and the General Health Questionaire–28 met all evaluation criteria. The PsychoSocial Screen for Cancer, the Questionnaire on Stress in Cancer Patients–Revised, and the Rotterdam Symptom Checklist are long measures that can also be recommended for routine screening. In addition, other measures may be considered for specific indications or disease types. Some measures, particularly newly developed cancer-specific scales, require further validation against structured clinical interviews (the criterion standard for validation measures) before they can be recommended.

Barriers to adherence and hypertension control in a racially diverse representative sample of elderly primary care patients

PURPOSE

To examine the effect of antihypertensive adherence on blood pressure and barriers to adherence in racially diverse elderly patients.

METHODS

Telephone survey of a representative sample of 300 of all 3416 hypertensive patients aged >70 from four urban primary care practices. From electronic records, we calculated subjects' annual mean systolic blood pressure. We asked about the last missed antihypertensive dose in six time intervals. Based on association with blood pressure control, non-adherence was defined as missing any dose in the past 3 months. Subjects were also asked about six domains of adherence barriers: health, personal support, drug coverage, medication filling and use, doctor-patient interaction and knowledge. All models adjust for demographics, treatment regimen and sampling weights.

RESULTS

The 202 subjects (67% response rate) were: female (65.9%), black (64.8%), mean age 77.4 years (5.49) and on mean 2.4 (SD 1.3) antihypertensive drugs. Mean annual systolic pressure for non-adherent subjects (22% of the cohort) was higher than adherent subjects (137.7 vs.133.4 mmHg, p = 0.065). After adjustment, the association between adherence and blood pressure was stronger in black than white patients (p = 0.007). In an initial model, being unaware of Medicare Part D had a lower adjusted odds ratio (AOR) of adherence (p < 0.05). In the final model, adherence barriers were: medication filling/use (run out of pills [AOR 0.25, CI 0.09-0.66] and 28% reduction per each of eight barriers); doctor-patient interaction (less important to discuss hypertension [AOR 0.32, CI 0.12-0.84]); and knowledge (38% lower AOR per incorrect answer about diseases unrelated to hypertension).

CONCLUSION

Self-reported adherence was associated with a higher blood pressure, especially in elderly black patients. To promote adherence, our data suggest targeting: filling prescriptions, prioritizing hypertension care and educating about effects of hypertension.

Sensitivity and specificity of the Beck Depression Inventory in cardiologic inpatients: how useful is the conventional cut-off score?

OBJECTIVE

The Beck Depression Inventory (BDI) is widely used for depression screening in various patient populations. However, there are still insufficient data about its sensitivity and specificity in nonpsychiatric patients. Furthermore, some research suggests that somatic BDI items heighten its sum score artificially in physically ill patients. The aim of the present study was to validate the conventional BDI cut-off score by examination of its sensitivity and specificity in a mixed sample of cardiac inpatients and compare it to a modified "cognitive-emotional" BDI (BDI(c/e)) after exclusion of somatic items.

METHODS

A total of 126 cardiologic inpatients were assessed. Receiver operating characteristic curves (ROC) were calculated for total BDI (BDI(t)) and BDI(c/e). Screening performance of cut-off scores was evaluated using the Youden Index (Y).

RESULTS

With the application of the conventional BDI cut-off score, ROC analysis revealed a moderate overall screening performance with Y=52.6 and an area under the curve (AUC) of 0.83. In contrast, Y improved to 57.5 at a cut-off score of >9, but screening performance was still not optimal. BDI(c/e) showed also a moderate screening performance (AUC=.82); Y was maximized at a cut-off score of >8 (Y=0.53.5). Again, no cut-off score provided optimal screening performance.

CONCLUSION

The BDI cannot be recommended as a formal screening instrument in cardiac inpatients since no cut-off score for either BDI(t) or BDI(c/e) combined both sufficiently high sensitivity and specificity. However, the shorter BDI(c/e) could be used as alternative to BDI(t) which may be confounded in physically ill patients. Generally, researchers should consider using alternative screening instruments (e.g., the Hospital Anxiety and Depression Scale) instead.

PTSD after severe vehicular crashes

PURPOSE

To describe predictors of PTSD after motor vehicle crashes (MVC).

METHODS

MVC patients were interviewed during their hospitalization and at 6 and 12 months post-injury. Interviews included information about behavioral factors, circumstances around the crash, recovery and PTSD screening. PTSD was defined as the development of 3 or more of 7 PTSD symptoms. Association of risk factors with PTSD development at 6 and 12 months was analyzed using contingency tables. Multiple regression models were built for the prediction of PTSD.

RESULTS

367 and 317 patients completed the 6 and 12 month interviews respectively. PTSD developed in 27.5 % (n=101) and 24.3 % (n=77) of the population at 6 and 12 months respectively. PTSD occurred more frequently among females, those with a previous history of depression, violent injury, or other traumatic events, and those whose crashes involved a fatality. Those who were culpable for the crash, age<30, and sustained brain injuries were less likely to develop PTSD at 6 months. Occupant position, education, marital status, alcohol problems, injury severity, heart rate, and blood alcohol + status did not show any significant association with PTSD. In the multiple logistic regression, female gender, history of depression, culpability, prior violent injury, and a fatality in the crash were associated with PTSD at 6 months. Only prior violent injury, and a death in same crash were predictors at one year.

CONCLUSION

PTSD occurs frequently after MVCs. Female gender, prior violent injury, death of another occupant and history of depression are associated with PTSD development.

Canadian Network for Mood and Anxiety Treatments (CANMAT) clinical guidelines for the management of major depressive disorder in adults. I. Classification, burden and principles of management

BACKGROUND

Major depressive disorder (MDD) is one of the most burdensome illnesses in Canada. The purpose of this introductory section of the 2009 revised CANMAT guidelines is to provide definitions of the depressive disorders (with an emphasis on MDD), summarize Canadian data concerning their epidemiology and describe overarching principles of managing these conditions. This section on "Classification, Burden and Principles of Management" is one of 5 guideline articles in the 2009 CANMAT guidelines.

METHODS

The CANMAT guidelines are based on a question-answer format to enhance accessibility to clinicians. An evidence-based format was used with updated systematic reviews of the literature and recommendations were graded according to the Level of Evidence using pre-defined criteria. Lines of Treatment were identified based on criteria that included evidence and expert clinical support.

RESULTS

Epidemiologic data indicate that MDD afflicts 11% of Canadians at some time in their lives, and approximately 4% during any given year. MDD has a detrimental impact on overall health, role functioning and quality of life. Detection of MDD, accurate diagnosis and provision of evidence-based treatment are challenging tasks for both clinicians and for the health systems in which they work.

LIMITATIONS

Epidemiologic and clinical data cannot be seamlessly linked due to heterogeneity of syndromes within the population.

CONCLUSIONS

In the eight years since the last CANMAT Guidelines for Treatment of Depressive Disorders were published, progress has been made in understanding the epidemiology and treatment of these disorders. Evidence supporting specific therapeutic interventions is summarized and evaluated in subsequent sections.

Brief depression screening with the PHQ-2 associated with prognosis following percutaneous coronary intervention with paclitaxel-eluting stenting

BACKGROUND

Depression is associated with adverse prognosis in cardiac patients, warranting the availability of brief and valid instruments to identify depressed patients in clinical practice.

OBJECTIVES

We examined whether the two-item Patient Health Questionnaire (PHQ-2) was associated with adverse events in percutaneous coronary intervention (PCI) patients treated with paclitaxel-eluting stenting (using the continuous score and various cutoffs), overall and by gender.

DESIGN

Prospective follow-up study.

PARTICIPANTS

Consecutive PCI patients (n = 796) seen at a university medical centre.

MEASUREMENTS

PHQ-2 at baseline. The study endpoint was an adverse event, defined as a combination of death or non-fatal myocardial infarction (MI) at follow-up (mean of 1.4 years).

RESULTS

At follow-up, 47 patients had experienced an adverse event. Using the continuous score of the PHQ-2 and the recommended cutoff > or =3, depressive symptoms were not associated with adverse events (ps > 0.05). Using a cutoff > or =2, depressive symptoms were significantly associated with adverse events (HR: 1.89; 95% CI: 1.06-3.35) and remained significant in adjusted analysis (HR: 1.90; 95% CI: 1.05-3.44). Depressive symptoms were associated with an increased risk of adverse events in men (HR: 2.69; 95% CI: 1.36-5.32) but not in women (HR: 0.76; 95% CI: 0.24-2.43); these results remained in adjusted analysis.

CONCLUSIONS

Depression screening with a two-item scale and a cutoff score of > or =2 was independently associated with adverse events at follow-up. The PHQ-2 is a brief and valid measure that can easily be used post PCI to identify patients at risk for adverse health outcomes.

The Cholesterol, Hypertension, and Glucose Education (CHANGE) study for African Americans with diabetes: study design and methodology

BACKGROUND

Cardiovascular disease (CVD) and diabetes account for over one third of the mortality difference between African Americans and white patients. The increased CVD risk in African Americans is due in large part to the clustering of multiple CVD risk factors.

OBJECTIVES

The current study is aimed at improving CVD outcomes in African-American adults with diabetes by addressing the modifiable risk factors of systolic blood pressure , glycosylated hemoglobin, and low-density lipoprotein cholesterol.

METHODS

A sample of African American patients with diabetes (N = 400) will receive written education material at baseline and be randomized to one of 2 arms: (1) usual primary care or (2) nurse-administered disease-management intervention combining patient self-management support and provider medication management. The nurse administered intervention is delivered monthly over the telephone. The nurses also interacts with the primary care providers at 3, 6, and 9 months to provide concise patient updates and facilitate changes in medical management. All patients are followed for 12 months after enrollment. The primary outcomes are change in glycosylated hemoglobin, systolic blood pressure, and low-density lipoprotein cholesterol over 12-months. Secondary outcomes include change in overall cardiovascular risk, aspirin use, and health behaviors.

CONCLUSION

Given the continued racial disparities in CVD, the proposed study could result in significant contributions to cardiovascular risk reduction in African-American patients.

Maternal depressive symptoms, depression, and psychiatric medication use in relation to risk of preterm delivery

PURPOSE

This study examined the associations among maternal depression, measured in several ways, psychiatric medication use in pregnancy, and preterm delivery (PTD).

METHODS

Data were collected from 3,019 women enrolled in the Pregnancy Outcomes and Community Health Study (1998-2004), a prospective study of pregnant women in five Michigan communities. Information on depressive symptoms, history of depression, and psychiatric medication use was ascertained through interviews at mid-pregnancy. These variables and other relevant covariates were incorporated into regression models with a binary outcome, that is, term (> or =37 weeks' gestation) as referent and PTD (<37 weeks' gestation). A second set of models used a multicategory outcome, namely, term as the referent and PTD further subdivided by gestational weeks and clinical circumstances.

MAIN FINDINGS

The odds of overall PTD was increased among women who used psychiatric medication during pregnancy and had either elevated levels of depressive symptoms at mid-pregnancy (adjusted odds ratio [AOR], 2.0; 95% confidence interval [CI], 1.1-3.6) or a history of depression before pregnancy (AOR, 1.6; 95% CI, 1.1-2.5). The combination of psychiatric medication use in pregnancy and depression, before pregnancy, or within pregnancy was most strongly linked to a medically indicated delivery before 35 weeks' gestation (AOR, 2.9 and 3.6, respectively).

CONCLUSIONS

There are at least two plausible explanations for these findings. First, psychiatric medication use in pregnancy may pose an excess risk of PTD. Second, medication use may be an indicator of depressive symptom severity, which is a direct or indirect (i.e., alters behavior) contributing factor to PTD.

Diagnostic accuracy of Spanish language depression-screening instruments

PURPOSE

To make decisions about implementing systematic depression screening, primary care physicians who serve Spanish-speaking populations need to know whether Spanish language depression-screening instruments are accurate. We aimed to review systematically the evidence regarding diagnostic accuracy of depression-screening instruments in Spanish-speaking primary care populations.

METHODS

We searched PubMed, PsycINFO, CINAHL, EMBASE, and Cochrane Libraries from inception to May 28, 2008, for studies examining the diagnostic accuracy of Spanish language depression case-finding instrument(s) administered to primary-care outpatients. Two authors independently assessed studies for inclusion and quality.

RESULTS

Twelve studies met inclusion criteria. In general primary care screening, the Spanish language version of the Center for Epidemiologic Studies-Depression scale (CES-D) had sensitivities ranging from 76% to 92% and specificities ranging from 70% to 74%. We found no US study reporting the accuracy of the Primary Care Evaluation of Mental Disorders (PRIME-MD-9) or the Patient Health Questionnaire (PHQ-9) depression module in Spanish-speakers. One fair-quality European study and 1 poor-quality study conducted in Honduras found the 9-item PRIME-MD had sensitivities ranging from 72% to 77% and specificities ranging from 86% to 100%. The 2-item PRIME-MD was 92% sensitive, but only 44% specific for depression in 1 US study. In geriatric outpatients, the 15-item Spanish language version of the Geriatric Depression Scale (GDS) had sensitivities ranging from 76% to 82%, and specificities ranging from 64% to 98%. In postpartum women, the Spanish language version of the Edinburgh Postnatal Depression Scale (EPDS) was 72% to 89% sensitive and 86% to 95% specific for major depression (2 non-US studies). The Spanish language version of the Postpartum Depression Screening Scale (PDSS) was 78% sensitive and 85% specific for combined major/minor depression (1 US study).

CONCLUSIONS

For depression screening in Spanish-speaking outpatients, fair evidence supports the diagnostic accuracy of the CES-D and PRIME-MD-9 in general primary care, the GDS-15-Spanish for geriatric patients, and the Spanish language versions of the EPDS or PDSS for postpartum patients. The ultrashort 2-item version of PRIME-MD may lack specificity in US Spanish-speakers.

Abbreviated brief symptom inventory for use as an anxiety and depression screening instrument in primary care

BACKGROUND

Screening for anxiety and depression in primary-care clinics has the potential to increase identification and treatment of affected patients. The feasibility of such screening, however, depends on the availability of quick, easily interpretable screening tools.

METHODS

In this pair of studies, a 4-item screening instrument was developed from the depression and anxiety scales of the Brief Symptom Inventory. One sample of undergraduate volunteers was used to identify pairs of items to be included in the screener. A second sample of primary-care patients was used to evaluate the performance of these items as compared to other measures of the same construct and a standardized clinical interview.

RESULTS

The studies suggest that 4 items from the Brief Symptom Inventory can be used to identify patients with depression and/or anxiety in primary care.

CONCLUSIONS

Circumstances under which this measure, compared to other measures such as the Patient Health Questionnaire, would be appropriate are discussed.

Screening for mood and anxiety disorders with the five-item, the three-item, and the two-item Mental Health Inventory

The Mental Health Inventory (MHI)-5 is an attractive, brief screening questionnaire for depression and anxiety disorders. It has been suggested that the three questions on depression (MHI-d) may be as good as the full MHI-5 in assessing depressive disorders. We examined the validity of the MHI-d and the MHI-a (the remaining two items on anxiety) in a large population-based sample of 7076 adults in the Netherlands. We also examined the validity of the MHI in assessing specific anxiety disorders. The presence of depressive and anxiety disorders in the past month was assessed with the Composite International Diagnostic Interview (CIDI), computerized version 1.1. ROC analyses indicated no significant difference between the MHI-5 (area under the curve of 0.93) and the MHI-d (area under the curve of 0.91) in detecting major depression and dysthymia. There was no difference either between the MHI-5 (area under the curve of 0.73) and the MHI-a (area under the curve 0.73) in detecting anxiety disorders. Both the MHI-5 and the MHI-a also seem to be adequate as a screener for some anxiety disorders (generalized anxiety disorder; panic disorder; obsessive-compulsive disorder), but not others, especially phobias (agoraphobia; social phobia; simple phobia).

Experience of a controlling or threatening partner among mothers with persistent symptoms of depression

OBJECTIVE

We evaluated the prevalence of symptoms of maternal depression (SMD) that continue beyond the postpartum period and the association between persistent SMD and reporting a controlling or threatening partner.

STUDY DESIGN

We combined data from a survey of mothers 2-6 months after delivery and its 2-year follow-up survey and analyzed the responses of 444 women who responded to both surveys. We focused on exposure to a controlling partner because this was the sole factor that was associated with persistent SMD in preliminary analysis.

RESULTS

Postpartum SMD was reported by 23% of the women. Among these women, 46% also reported SMD 2 years later. In bivariate analysis, a controlling partner was associated with persistent SMD (odds ratio, 6.9; 95% confidence interval, 1.5-31.8; P = .014).

CONCLUSION

Almost one-half of women with postpartum SMD continue to have symptoms 2 years later. Further research is needed to measure the strength of the association between controlling partners and persistent depression.

Specialty care and education associated with greater disease-specific knowledge but not satisfaction with care for chronic hepatitis C

BACKGROUND

Little is known about differences among hepatitis C virus (HCV) patients managed by generalists vs. specialists with respect to patient-centred outcomes, such as disease-specific knowledge, health-related quality of life (HRQoL) and satisfaction with care.

AIM

To examine selected patient-centred outcomes of HCV-related care provided in primary care, specialty care or both.

METHODS

A total of 629 chronic HCV patients completed a survey including an HCV knowledge assessment and validated instruments for satisfaction and HRQoL. Multivariable linear regression was used to compare outcomes between groups.

RESULTS

Adjusted total HCV knowledge score was lower among patients who did not attend specialty care (P < 0.01). Primary care and specialty patients did not differ in adjusted general HRQoL or satisfaction. Sixty percent of specialty patients underwent formal HCV education, which was associated with 5% higher knowledge score (P = 0.01). General HRQoL and patient satisfaction did not differ between primary care and specialty groups. Disease-specific knowledge and care satisfaction were independent of mental illness, substance abuse, socio-economic variables, history of antiviral treatment, formal HCV education and duration of time between last visit and survey completion.

CONCLUSIONS

Primary care patients with chronic HCV have lower adjusted disease-specific knowledge than specialty patients, but no difference in general HRQoL or patient satisfaction.

Implementation of Internet-based preventive interventions for depression and anxiety: role of support? The design of a randomized controlled trial

Background

Internet-based self-help is an effective preventive intervention for highly prevalent disorders, such as depression and anxiety. It is not clear, however, whether it is necessary to offer these interventions with professional support or if they work without any guidance. In case support is necessary, it is not clear which level of support is needed. This study examines whether an internet-based self-help intervention with a coach is more effective than the same intervention without a coach in terms of clinical outcomes, drop-out and economic costs. Moreover, we will investigate which level of support by a coach is more effective compared to other levels of support.

Methods

In this randomized controlled trial, a total of 500 subjects (18 year and older) from the general population with mild to moderate depression and/or anxiety will be assigned to one of five conditions: (1) web-based problem solving through the internet (self-examination therapy) without a coach; (2) the same as 1, but with the possibility to ask help from a coach on the initiative of the respondent (on demand, by email); (3) the same as 1, but with weekly scheduled contacts initiated by a coach (once per week, by email); (4) weekly scheduled contacts initiated by a coach, but no web-based intervention; (5) information only (through the internet). The interventions will consist of five weekly lessons. Primary outcome measures are symptoms of depression and anxiety. Secondary outcome measures are drop-out from the intervention, quality of life, and economic costs. Other secondary outcome measures that may predict outcome are also studied, e.g. client satisfaction and problem-solving skills. Measures are taken at baseline (pre-test), directly after the intervention (post-test, five weeks after baseline), 3 months later, and 12 months later. Analysis will be conducted on the intention-to-treat sample.

Discussion

This study aims to provide more insight into the clinical effectiveness, differences in drop-out rate and costs between interventions with and without support, and in particular different levels of support. This is important to know in relation to the dissemination of internet-based self-help interventions.

Behavioral medicine for migraine

Behavioral medicine is based on the biopsychosocial theory that biological, psychological, and environmental factors all play significant roles in human functioning. This article reviews empirically supported and efficacious behavioral approaches to the treatment and management of migraine including cognitive behavioral therapy and biobehavioral training (ie, biofeedback, relaxation training, and stress management). These techniques have demonstrated efficacy when learned and practiced correctly and may be used individually or in conjunction with pharmacologic and other interventions. Data are also reviewed regarding patient education, support groups, psychological comorbidities, modifiable risk factors for headache progression, strategies for enhancing adherence and motivation, and strategies for effective medical communication.

Use of a normal impairment factor in quantifying avoidable productivity loss because of poor health

OBJECTIVE

Growing evidence demonstrates a relationship between excess health risk and preventable productivity loss. There is a need to quantify how much lost productivity is avoidable through employer-sponsored health management interventions. This study introduced the Normal Impairment Factor (NIF) to recognize the amount of productivity loss that cannot be mitigated through health management interventions.

METHODS

A health assessment questionnaire was administered to 772,750 employees, representing 106 employers within five industry sectors. Researchers used multivariate regression procedures to examine the association between preventable health risks and self-reported productivity loss.

RESULTS

Back pain, mental well being, and stress risk were the strongest predictors of on-the-job productivity loss. A strong association was also detected between the number of health risks and productivity loss ranging from 3.4% for those at lowest risk (the NIF group) to 24.0% loss for those at risk for eight risks.

CONCLUSIONS

This study demonstrated the utility of the NIF in estimating the level of productivity loss that cannot be regained through health management interventions.

Accuracy of specific symptoms in the diagnosis of major depressive disorder in psychiatric out-patients: data from the MIDAS project

BACKGROUND

There is uncertainty about the diagnostic significance of specific symptoms of major depressive disorder (MDD). There is also interest in using one or two specific symptoms in the development of brief scales. Our aim was to elucidate the best possible specific symptoms that would assist in ruling in or ruling out a major depressive episode in a psychiatric out-patient setting.

METHOD

A total of 1523 psychiatric out-patients were evaluated in the Methods to Improve Diagnostic Assessment and Services (MIDAS) project. The accuracy and added value of specific symptoms from a comprehensive item bank were compared against the Structured Clinical Interview for DSM-IV (SCID).

RESULTS

The prevalence of depression in our sample was 54.4%. In this high prevalence setting the optimum specific symptoms for ruling in MDD were psychomotor retardation, diminished interest/pleasure and indecisiveness. The optimum specific symptoms for ruling out MDD were the absence of depressed mood, the absence of diminished drive and the absence of loss of energy. However, some discriminatory items were relatively uncommon. Correcting for frequency, the most clinically valuable rule-in items were depressed mood, diminished interest/pleasure and diminished drive. The most clinically valuable rule-out items were depressed mood, diminished interest/pleasure and poor concentration.

CONCLUSIONS

The study supports the use of the questions endorsed by the two-item Patient Health Questionnaire (PHQ-2) with the additional consideration of the item diminished drive as a rule-in test and poor concentration as a rule-out test. The accuracy of these questions may be different in primary care studies where prevalence differs and when they are combined into multi-question tests or algorithmic models.

Parental depressive symptoms: relationship to child development, parenting, health, and results on parent-reported screening tools

OBJECTIVE

To determine whether parents with depressive symptoms can accurately complete parent-reported developmental screens, and to explore effects of parental depressive symptoms on perceptions of children's health and parenting behaviors.

STUDY DESIGN

A total of 382 parent-child (ages 0 to 2 years) dyads from pediatric sites across 17 U.S. states were evaluated with the directly administered and parent-reported Brigance Infant Toddler Screen, the Brigance Parent-Child Interactions Scale, a child development and health rating scale, and a caretaker depression screen. Groups were compared by parental status by depression screening.

RESULTS

Fifteen percent of parents had positive scores on screening for depression. Parents with a positive screen result for depression were twice as likely to rate their children as below average or average and to perceive health problems in their children. Their children were 1.7 times more likely to perform below Brigance Screen cutoffs. Parents with a positive screen result for depression were as accurate as parents with a negative screen result for depression in identifying delayed or average development but were significantly less likely to rate their above-average children as such and reported fewer positive parenting practices.

CONCLUSION

Parents with a positive depression screen result were as accurate in identifying developmental problems as parents with a negative depression screen result. Parental depressive symptoms are negatively associated with parenting behaviors, parental perspective on health and development, and child outcomes, which supports screening for depression and intervening promptly.

Practical depression screening in residential care/assisted living: five methods compared with gold standard diagnoses

OBJECTIVE

To test the accuracy of five practical depression screening strategies in older adults residing in residential care/assisted living (RC/AL).

DESIGN

Cross-sectional screening study.

SETTING

Four RC/AL communities in North Carolina.

PARTICIPANTS

A total of 112 residents aged > or =65 and 27 staff members involved in their care.

MEASUREMENTS

Direct care staff was trained in and completed the Cornell Scale for Depression in Dementia, modified for use by long-term care staff (CSDD-M-LTCS). They additionally responded to a one-item question "Do you believe the resident is often sad or depressed?" and the Minimum Data Set Depression Rating Scale (DRS). Residents responded directly to the Geriatric Depression Scale (15-item version; GDS-15) and the Patient Health Questionnaire, 2-item version (PHQ-2). A geriatric psychiatrist performed gold standard diagnostic interviews using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Sensitivities and specificities were calculated for all instruments at predetermined cutpoints.

RESULTS

Gold standard diagnoses yielded 14% prevalence of major or minor depression. The CSDD-M-LTCS and one-item screen completed by caregivers failed to significantly discriminate depressed cases. The DRS yielded high specificity (0.85) but low sensitivity (0.47). For the two resident reported measures, the PHQ-2 had a sensitivity of 0.80 and specificity of 0.71, and the GDS-15, 0.60 and 0.75, respectively.

CONCLUSION

Measures completed by caregivers failed to adequately detect depression. Of the measures completed directly by residents, the PHQ-2 seems to have the best mix of brevity, sensitivity, and ease of administration.

The prevalence of depression in hereditary spastic paraplegia

OBJECTIVE

To evaluate the prevalence of depression and sensitivity and specificity of the single-item interview 'Are you depressed?' for people with hereditary spastic paraplegia in Estonia.

DESIGN

Single-item interview 'Are you depressed?' was used as a screening question for depression; all participants then completed the Beck Depression Inventory.

SETTING

People with hereditary spastic paraplegia identified from the epidemiological database who agreed to participate in the study.

MAIN MEASURES

Beck Depression Inventory, clinical interview.

RESULTS

The epidemiological database consisted of 59 patients with clinically confirmed diagnosis of hereditary spastic paraplegia. Forty-eight of these consented to participate in the study. The Beck Depression Inventory score was higher than cut-off point in 58% (28/48) and lower in 42% (20/48). Of the study group, 44% (21/48) had mild, 13% (6/48) moderate and one person revealed severe depression. There was a statistically significant correlation between Beck Depression Inventory score and level of mobility; no other significant correlations with other measures were detected. Of the participants, 54% (26/48) had subjective complaints about depression and answered 'Yes' to the single-item interview 'Are you depressed?'. The sensitivity of the one-item interview in the hereditary spastic paraplegia group was 75% and specificity 75%.

CONCLUSIONS

Our results show that mild depression is prevalent among people with hereditary spastic paraplegia. Although the single question may be helpful, it cannot be relied upon entirely when assessing a person for depression.

Does a single-item measure of depression predict mortality?

OBJECTIVE

To determine if a single-item measure of depression predicts mortality over 5 years.

DESIGN

Secondary analysis of a population-based cohort study.

SETTING

Province of Manitoba.

PARTICIPANTS

A total of 1751 community-dwelling adults aged 65 years or older.

MAIN OUTCOME MEASURES

Self-reported depression; age, sex, education, functional status, and cognition; death over 5 years. Depression was measured with 1 item drawn from the Center for Epidemiologic Studies Depression (CES-D) scale: "I felt depressed." Bivariate and multivariate analyses were conducted.

RESULTS

Those with self-reported depression had a 5-year mortality of 30.2% versus 19.7% in those without self-reported depression (P < .001, chi2). This association persisted after adjustment for age, sex, education, functional status, and cognition: adjusted odds ratio for mortality 1.35 (95% confidence interval 1.03 to 1.76). Among those with cognitive impairment, however, neither the CES-D scale nor the single-item measure predicted mortality.

CONCLUSION

A simple measure of depression drawn from the CES-D predicts mortality among cognitively intact community-dwelling older adults, but not among cognitively impaired older adults. Further study is needed in order to determine the usefulness of this question in clinical practice.

Problem-solving treatment and coping styles in primary care for minor depression

Research was undertaken to compare problem-solving treatment for primary care (PST-PC) with usual care for minor depression and to examine whether treatment effectiveness was moderated by coping style. PST-PC is a 6-session, manual-based, psychosocial skills intervention. A randomized controlled trial was conducted in 2 academic, primary care clinics. Those subjects who were eligible were randomized (N = 151), and 107 subjects completed treatment (57 PST-PC, 50 usual care) and a 35-week follow-up. Analysis with linear mixed modeling revealed significant effects of treatment and coping, such that those in PST-PC improved at a faster rate and those initially high in avoidant coping were significantly more likely to have sustained benefit from PST-PC.

Suicide Prevention with Adolescents

Background/Aims: Suicide is one of the most serious public health challenges; yet determining optimal methods for preventing suicide in adolescents continues to be an elusive goal. The aim of this study was to investigate possible benefits and untoward effects of suicide-prevention public service announcements (PSAs) for adolescents. Methods: Adolescent participants (N = 426; 56% female) were randomly assigned to one of three conditions: (a) a billboard simulation, (b) a 30-s TV ad simulation, and (c) a no-information condition. Results: The results of this study suggest some benefits for the information conveyed by the TV ad (e.g., more knowledgeable about depression). Few benefits were noted for adolescents who were exposed to billboard simulation, and the results raised substantial concerns about possible untoward effects, particularly in adolescents who were exhibiting depressive or suicidal symptoms. Billboard viewers were less likely to favor help-seeking attitudes, perceived PSAs as being less useful, and endorsed more maladaptive coping. Conclusions: More research is urgently needed so that well-intended efforts to prevent suicide can more optimally serve the desired goals.

Association of insomnia severity and comorbid medical and psychiatric disorders in a health plan-based sample: Insomnia severity and comorbidities

BACKGROUND

Insomnia is commonly associated with one or more comorbid illnesses. Data on the relationship between insomnia severity and comorbid disorders are still limited, especially with regard to the use of well-validated measures of insomnia severity.

METHODS

A total of 2086 health plan enrollees, over-sampling for those with insomnia based on health claims, completed a telephone survey between April and June of 2006. Participants were categorized using four insomnia severity categories and compared on their administrative health claims' psychiatric and medical comorbidities.

RESULTS

Controlling for age and gender, the odds ratio for having at least one psychiatric diagnosis was 5.04 (CI=3.24-7.84) for severe insomnia, 2.63 (CI=1.97-3.51) for moderate insomnia, and 1.7 (CI=1.30-2.23) for subthreshold insomnia compared with those with no insomnia. Similarly, the odds ratio for having treatment for at least one chronic disease was 2.83 (CI=1.84-4.35) for severe insomnia, 2.34 (CI=1.83-2.99) for moderate insomnia, and 1.55 (CI=1.25-1.92) for subthreshold insomnia compared with the no insomnia group.

CONCLUSIONS

Increasing insomnia severity is associated with increased chronic medical and psychiatric illnesses. Further research is needed to better understand associations between insomnia severity and individual psychiatric and chronic medical comorbidities.

Daytime Sleepiness and Functional Outcomes in Older Adults With Diabetes

Purpose

This secondary analysis examined the effect of excessive sleepiness on daytime function in older adults with diabetes from the National Sleep Foundation's Sleep and Aging poll.

Methods

Respondents were older adults (N = 1506; age range, 55-84 years) evaluated by telephone survey on their sleep duration, sleep disturbances, daytime functional outcomes, and self-reported height, weight, and comorbidities.

Results

Approximately 16% (n = 244) of the sample acknowledged a diagnosis of diabetes; they were older, had more comorbidities, had a higher body mass index (BMI), and were more likely to be sleepy during the daytime than nondiabetic respondents (all P < .05). Respondents with diabetes who reported frequent daytime sleepiness (n = 50; 20%) had significantly (P < .05) higher BMI, lower self-rated health, and more sleep disturbances than those who were not sleepy (n = 194). Sleepy respondents with diabetes also reported more frequent feelings of depression, decreased pleasure in life, naps, feeling drowsy, or dozing off while driving (all P < .05). Excessive sleepiness was significantly associated (P < .001) with an increased risk for depressive symptoms while controlling for BMI, age, and number of comorbidities.

Conclusions

These results indicate that sleep disturbances affect not only sleep quality but also daytime function in older adults with diabetes.

A systematic review of studies validating the Edinburgh Postnatal Depression Scale in antepartum and postpartum women

OBJECTIVE

The Edinburgh Postnatal Depression Scale (EPDS) is the most widely used screening tool for postpartum depression (PPD). We systematically reviewed the published evidence on its validity in detecting PPD and antepartum depression (APD) up to July 2008.

METHOD

Systematic review of validation studies of the EPDS included 1987-2008. Cut-off points of 9/10 for possible PPD, 12/13 for probable PPD and 14/15 for APD were used.

RESULTS

Thirty-seven studies met the inclusion criteria. Sensitivity and specificity of cut-off points showed marked heterogeneity between different studies. Sensitivity results ranged from 34 to 100% and specificity from 44 to 100%. Positive likelihood ratios ranged from 1.61 to 78.

CONCLUSION

Heterogeneity among study findings may be due to differences in study methodology, language and diagnostic interview/criteria used. Therefore, the results of different studies may not be directly comparable and the EPDS may not be an equally valid screening tool across all settings and contexts.

[Review of the guidelines of the Brazilian Medical Association for the treatment of depression (Complete version)]

OBJECTIVE

Depression is a frequent, recurrent and chronic condition with high levels of functional disability. The Brazilian Medical Association Guidelines project proposed guidelines for diagnosis and treatment of the most common medical disorders. The objective of this paper is to present a review of the Guidelines Published in 2003 incorporating new evidence and recommendations.

METHOD

This review was based on guidelines developed in other countries and systematic reviews, randomized clinical trials and when absent, observational studies and recommendations from experts. The Brazilian Medical Association proposed this methodology for the whole project. The review was developed from new international guidelines published since 2003.

RESULTS

The following aspects are presented: prevalence, demographics, disability, diagnostics and sub-diagnosis, efficacy of pharmacological and psychotherapeutic treatment, costs and side-effects of different classes of available drugs in Brazil. Strategies for different phases of treatment are also discussed.

CONCLUSION

The Guidelines are an important tool for clinical decisions and a reference for orientation based on the available evidence in the literature.

Training residents to employ self-efficacy-enhancing interviewing techniques: randomized controlled trial of a standardized patient intervention

BACKGROUND

Current interventions to enhance patient self-efficacy, a key mediator of health behavior, have limited primary care application.

OBJECTIVE

To explore the effectiveness of an office-based intervention for training resident physicians to use self-efficacy-enhancing interviewing techniques (SEE IT).

DESIGN

Randomized controlled trial.

PARTICIPANTS

Family medicine and internal medicine resident physicians (N = 64) at an academic medical center.

MEASUREMENTS

Resident use of SEE IT (a count of ten possible behaviors) was coded from audio recordings of the physician-patient portion of two standardized patient (SP) instructor training visits and two unannounced post-training SP visits, all involving common physical and mental health conditions and behavior change issues. One post-training SP visit involved health conditions similar to those experienced in training, while the other involved new conditions.

RESULTS

Experimental group residents demonstrated significantly greater use of SEE IT than controls, starting after the first training visit and sustained through the final post-training visit. The mean effect of the intervention was significant [adjusted incidence rate ratio for increased use of SEE IT = 1.94 (95% confidence interval = 1.34, 2.79; p < 0.001)]. There were no significant effects of resident gender, race/ethnicity, specialty, training level, or SP health conditions.

CONCLUSIONS

SP instructors can teach resident physicians to apply SEE IT during SP office visits, and the effects extend to health conditions beyond those used for training. Future studies should explore the effects of the intervention on practicing physicians, physician use of SEE IT during actual patient visits, and its influence on patient health behaviors and outcomes.

Depression screening using the Patient Health Questionnaire-9 administered on a touch screen computer

OBJECTIVE

To (1) evaluate the feasibility of touch screen depression screening in cancer patients using the Patient Health Questionnaire-9 (PHQ-9), (2) evaluate the construct validity of the PHQ-9 using the touch screen modality, and (3) examine the prevalence and severity of depression using this screening modality.

METHODS

The PHQ-9 was placed in a web-based survey within a study of the clinical impact of computerized symptom and quality of life screening. Patients in medical oncology, radiation oncology, and hematopoietic stem cell transplantation (HSCT) clinics used the program on a touch screen computer in waiting rooms prior to therapy (T1) and during therapy (T2). Responses of depressed mood or anhedonia (PHQ-2 cardinal depression symptoms) triggered additional items. PHQ-9 scores were provided to the oncology team in real time.

RESULTS

Among 342 patients enrolled, 33 (9.6%) at T1 and 69 (20.2%) at T2 triggered the full PHQ-9 by endorsing at least one cardinal symptom. Feasibility was high, with at least 97% completing the PHQ-2 and at least 96% completing the PHQ-9 when triggered and a mean completion time of about 2 min. The PHQ-9 had good construct validity. Medical oncology patients had the highest percent of positive screens (12.9%) at T1, while HSCT patients had the highest percent (30.5%) at T2. Using this method, 21 (6.1%) at T1 and 54 (15.8%) at T2 of the total sample had moderate to severe depression.

CONCLUSIONS

The PHQ-9 administered on a touch screen computer is feasible and provides valid depression data in a diverse cancer population.

Modifiable factors associated with changes in postpartum depressive symptoms

Up to 50% of mothers report postpartum depressive symptoms yet providers do a poor job predicting and preventing their occurrence. Our goal was to identify modifiable factors (situational triggers and buffers) associated with postpartum depressive symptoms. Observational prospective cohort telephone study of 563 mothers interviewed at 2 weeks and 6 months postpartum. Mothers reported on demographic factors, physical and emotional symptoms, daily function, infant behaviors, social support, and skills in managing infant and household. Mothers were categorized into four groups based on the presence of depressive symptoms at 2 weeks and at 6 months postpartum: never, always, late onset, and remission groups. Fifty-two percent did not have depressive symptoms at 2 weeks or at 6 months (never group), 14% had symptoms at both time points (always group), 10% had late onset, and 24% had early onset of symptoms with remission. As compared with women in the never group, women in the always and late onset groups had high-risk characteristics (e.g., past history of depression), more situational triggers (e.g., physical symptoms), and less robust social and personal buffers (i.e., social support and self-efficacy). As compared with the never group, mothers in the remission group had more situational triggers and fewer buffers initially. Changes in situational triggers and buffers were different for the four groups and were correlated with group membership. Situational triggers such as physical symptoms and infant colic, and low levels of social support and self-efficacy in managing situational demands are associated with postpartum depressive symptoms. Further research is needed to investigate whether providing education about the physical consequences of childbirth, providing social support, and teaching skills to enhance self-efficacy will reduce the incidence of postpartum symptoms of depression.

Reliability and validity of prehospital case finding for depression and cognitive impairment

OBJECTIVES

To evaluate the test-retest reliability, the concurrent criterion validity, and the construct validity of prehospital, emergency medical service (EMS) case finding for depression and cognitive impairment in older adults.

DESIGN

Cross-sectional study.

SETTING

Prehospital EMS system and hospital emergency department.

PARTICIPANTS

EMS providers and community-dwelling older adult (aged > or =60) patients.

INTERVENTIONS

Case finding instruments for depression (Patient Health Questionnaire-2; PHQ-2) and cognitive impairment (Six-Item Screener).

MEASUREMENTS

The reliability and validity of these instruments.

RESULTS

Moderate test-retest reliability was found for prehospital application of the PHQ-2 (kappa=0.50) and Six-Item Screener (kappa=0.52), fair concurrent criterion validity for depression (kappa=0.36), and slight to fair concurrent criterion validity for cognitive impairment (kappa=0.11-0.23). Construct validity was demonstrated using the Multitrait-Multimethod Matrix.

CONCLUSION

Moderate test-retest reliability and construct validity were demonstrated for prehospital case finding by EMS providers for cognitive impairment and depression using these instruments. Slight to fair concurrent criterion validity was found, a result that methodological limitations could explain. These findings provide additional support for the concept of using EMS providers to detect older adults at risk for these conditions. Further work is needed to confirm the validity and effectiveness of prehospital screening before such programs are implemented.

Depression in the elderly in Vellore, South India: the use of a two-question screen

BACKGROUND

Depression in the elderly is a common and disabling condition. The aim of the study was to evaluate the sensitivity and specificity of a two-question screen to identify depression and common mental disorders in the elderly.

METHOD

Residents of a ward in the town of Vellore were identified by a door-to-door survey from which 204 subjects aged over 60 years were selected for the study by systematic random sampling. They were screened using the two-question screen. The Revised Clinical Interview Schedule (CIS-R) was employed to confirm the diagnosis.

RESULTS

The prevalence of depression and common mental disorder, using the CIS-R standard, was found to be 31.5%. The two-question screen has a sensitivity of 93.8% and specificity of 48.2%.

CONCLUSIONS

The high sensitivity of the two-question screen makes it a useful screening method which can be employed by health workers in the field.

Xanthogranulomatous inflammation of the colon: a rare cause of cecal mass with bleeding

Xanthogranulomatous inflammation is a well-defined disease most frequently reported in the kidney and gallbladder. The occurrence of this disease in the colon is extremely rare, with only five cases of appendix vermiformis involvement in the literature. Its clinical importance is that it can be misinterpreted as a malignant process clinically and intraoperatively as well as in the imaging studies. In this report, a 57-year-old patient presented with a cecal mass that caused recurrent lower gastrointestinal bleeding and anemia, mimicking colon cancer. This is the first report of this lesion involving the cecum with typical macroscopic and microscopic features but with atypical clinical symptoms and findings.

A multicenter study of major depressive disorder among emergency department patients in Latin-American countries

This multicenter study estimated the prevalence of major depressive disorder (MDD) among emergency department patients in Latin America. To identify patients with MDD, we used a combination of DSM IV- criteria interview and a questionnaire screen including the center for Epidemiological Studies Depression Scale. We analyzed data from consecutive adult patients from hospitals in Argentina, Brazil, Chile, Colombia, and Mexico and described the demographic and health status differences between MDD and non-MDD patients. Prevalence of MDD ranges from 23.0 to 35.0%. The estimates are based on a total of 1,835 patients aged 18 years and over, with response rates of 83.0%. Compared to non-MDD patients, MDD patients were more likely to be middle-aged, female, smokers, of lower socioeconomic status, and to report a diagnosis of asthma or arthritis/rheumatism. Multivariate analysis identified a lower level of education, smoking, and self-reported anxiety, chronic fatigue, and back problems to be independently associated with MDD. Our data suggest that the prevalence of MDD is elevated among emergency department patients in Latin American countries. The integration of depression screening into routine emergency care merits serious consideration, especially if such screening can be linked to psychiatric treatment.

The relationships between depression and brain tumors

Depression is a common complication/co-morbidity in patients with brain tumors. Better understanding of the relationships between brain tumors and depression should lead to improvement in patient care. This paper reviews these relationships in order to direct further study to improve patient care, and hopefully, outcome. Both anatomic and physiological perturbations in the brain are likely involved in the associations between depression and brain tumors. Tumor treatments are also associated with depression. Depression has a significant negative impact on outcome in brain tumor patients. The role of treatment of depression in brain tumor patients has been scantly studied. Further investigation directed to these areas of knowledge deficit should benefit depressed patients with brain tumors.

Brief intervention for anxiety in primary care patients

To address the difficulty of assessing and managing multiple anxiety disorders in the primary care setting, this article provides a simple, easy-to-learn, unified approach to the diagnosis, care management, and pharmacotherapy of the 4 most common anxiety disorders found in primary care: panic, generalized anxiety disorders, social anxiety disorders, and posttraumatic stress disorder. This evidence-based approach was developed for an ongoing National Institute of Mental Health-funded study designed to improve the delivery of evidence-based medication and psychotherapy treatment to primary care patients with these anxiety disorders. We present a simple, validated method to screen for the 4 major disorders that emphasizes identifying other medical or psychiatric comorbidities that can complicate treatment; an approach for initial education of the patient and discussion about treatment, including provision of some simple cognitive behavioral therapy skills, based on motivational interviewing/brief intervention approaches previously used for substance use disorders; a validated method for monitoring treatment outcome; and an algorithmic approach for the selection of initial medication treatment, the selection of alternative or adjunctive treatments when the initial approach has not produced optimal results, and indications for mental health referral.
