Monitoring Depression Treatment Outcomes With the Patient Health Questionnaire-9

[Screening for psychiatric risk factors in a facial trauma patients. Validating a questionnaire]

INTRODUCTION

We recorded similarities between patients managed in the psychiatry department and in the maxillo-facial surgical unit. Our hypothesis was that some psychiatric conditions act as risk factors for facial trauma. We had for aim to test our hypothesis and to validate a simple and efficient questionnaire to identify these psychiatric disorders.

MATERIALS AND METHODS

Fifty-eight consenting patients with facial trauma, recruited prospectively in the 3 maxillo-facial surgery departments of the Marseille area during 3 months (December 2012-March 2013) completed a self-questionnaire based on the French version of 3 validated screening tests (Self Reported Psychopathy test, Rapid Alcohol Problem Screening test quantity-frequency, and Personal Health Questionnaire).

RESULTS

This preliminary study confirmed that psychiatric conditions detected by our questionnaire, namely alcohol abuse and dependence, substance abuse, and depression, were risk factors for facial trauma.

DISCUSSION

Maxillo-facial surgeons are often unaware of psychiatric disorders that may be the cause of facial trauma. The self-screening test we propose allows documenting the psychiatric history of patients and implementing earlier psychiatric care.

Pruritus is associated with severely impaired quality of life in patients with primary sclerosing cholangitis

OBJECTIVES

Quality of life, fundamental to the individual patient, has shown a lack of correlation with severity in research on several diseases. Thus, we aimed to identify factors associated with quality of life in patients with primary sclerosing cholangitis.

METHODS

The Short Form Health Survey and the Patient Health Questionnaire were used to assess quality of life and depression. Complete data sets of 113 patients were analyzed for correlation with sex, age, presence of concomitant inflammatory bowel disease and dominant stenosis, frequency of pruritus, and Mayo Risk Score.

RESULTS

Physical functioning decreased with age (P<0.001). Further, women experienced more prominent role limitations because of physical (P<0.03) and emotional (P<0.01) problems. Although patients' quality of life and depression scores were only slightly lower than normal, more frequent pruritus was associated with a considerable reduction in quality of life in terms of physical and social functioning, general and mental health, bodily pain, vitality, and roles (because of physical problems) (P<0.01). It did not differ significantly according to the Mayo Risk Score or the presence of dominant stenoses. Depression scores were only significantly affected in patients with more frequent pruritus.

CONCLUSION

Pruritus severely affects quality of life in patients with primary sclerosing cholangitis and is associated with depression to varying extents, although the most commonly used parameters of disease severity do not correspond to quality of life in these patients. These findings need to be considered with respect to treatment outcomes and indications for liver transplantation.

Decreasing the duration of untreated illness for individuals with anorexia nervosa: study protocol of the evaluation of a systemic public health intervention at community level

BACKGROUND

Anorexia nervosa (AN) is a mental disorder with grave burdens for affected individuals as well as for the healthcare system. One of the strongest predictors of a poor outcome is a long Duration of Untreated Illness (DUI), which is defined as the time between the onset of the disease and treatment initiation. Reducing the DUI is an important step to optimize care of individuals with AN. In order to achieve this aim, systemic public health interventions are necessary. Objective of this study is to evaluate a systemic public health intervention at Community level aiming to reduce the DUI in individuals with AN.

METHODS/DESIGN

The intervention includes the establishment of a network of health care professionals within the area of eating disorders (EDs), the development of an internet-based treatment guide, the presentation of informative short-films about EDs in cinemas and a corresponding poster campaign as well as a special outpatient clinic. For the evaluating study a pre-post between-subject design is chosen. The DUI, and the duration until first contact (DUC) with a health care professional, ED pathology as well as comorbidity are assessed before and after the systemic intervention is carried out.

DISCUSSION

The study attempts to provide evidence of the effectiveness of an ED-related systematic public health intervention. Additionally, the study will lead to a better understanding of the DUI, which is essential in order to improve care of individuals with AN.

Orthopaedic trauma patients and depression: a prospective cohort

OBJECTIVES

This study prospectively followed a cohort of orthopaedic trauma patients to identify risk factors that contribute to depression in patients with skeletal injuries.

DESIGN

Prospective cohort study.

SETTING

Level I trauma center.

PATIENTS

One hundred ten orthopaedic trauma patients admitted as inpatients.

INTERVENTION

None.

MAIN OUTCOME MEASUREMENTS

Patient Health Questionnaire (PHQ-9) scores.

RESULTS

One hundred ten patients were enrolled at the time of injury in which 22 patients had moderate-to-major depression and 36 patients had mild depression. Forty-eight patients completed the follow-up surveys that were taken, on average, 9 months after the date of injury. Factors that were significant for mild depression (PHQ-9 >4) at the time of injury included a history of illegal drug use (P = 0.037) and a lower Duke Social Support and Stress Scale (DUSOCS) support score (P = 0.002). The duke social support and stress scale score had a negative Pearson correlation coefficient with PHQ-9 (n = -0.18, P = 0.03). Factors that were significant for moderate-to-major depression (PHQ-9 >9) at the time of injury were a history of a psychiatric diagnosis (P = 0.0009) and unemployment at injury (P = 0.039). Both a history of psychiatric diagnosis and an elevated PHQ-9 score at the time of injury were predictors of having depression at 9 months (P = 0.02 and P = 0.001, respectively). Also, patients with Medicaid insurance had a significant increase in their depression scores at 9 months (P = 0.02).

CONCLUSION

Depression was quite prevalent in our patient sample. A previous psychiatric diagnosis predisposed patients to depression. The socioeconomic status was also a predictive factor for increased depression scores at 9 months. Patients with a higher feeling of support from friends and family had an inverse correlation for depression. Employment also seems to have a protective effect against depression. Surprisingly, the severity of injury did not affect the depression score. Targeted consultation with a mental health care provider may obviate any morbidity that is associated with depression in an injured patient.

HIV, multidrug-resistant TB and depressive symptoms: when three conditions collide

Background

Management of multidrug-resistant TB (MDR-TB) patients co-infected with human immunodeficiency virus (HIV) is highly challenging. Such patients are subject to long and potentially toxic treatments and may develop a number of different psychiatric illnesses such as anxiety and depressive disorders. A mental health assessment before MDR-TB treatment initiation may assist in early diagnosis and better management of psychiatric illnesses in patients already having two stigmatising and debilitating diseases.

Objective

To address limited evidence on the baseline psychiatric conditions of HIV-infected MDR-TB patients, we aimed to document the levels of depressive symptoms at baseline, and any alteration following individualized clinical and psychological support during MDR-TB therapy, using the Patient Health Questionnaire-9 (PHQ-9) tool, among HIV-infected patients.

Design

This was a retrospective review of the medical records of an adult (aged >15 years) HIV/MDR-TB cohort registered for care during the period of August 2012 through to March 2014.

Results

A total of 45 HIV/MDR-TB patients underwent baseline assessment using the PHQ-9 tool, and seven (16%) were found to have depressive symptoms. Of these, four patients had moderate to severe depressive symptoms. Individualized psychological and clinical support was administered to these patients. Reassessments were carried out for all patients after 3 months of follow-up, except one, who died during the period. Among these 44 patients, three with baseline depressive symptoms still had depressive symptoms. However, improvements were observed in all but one after 3 months of follow-up.

Conclusion

Psychiatric illnesses, including depressive symptoms, during MDR-TB treatment demand attention. Routine administration of baseline mental health assessments by trained staff has the potential to assist in determining appropriate measures for the management of depressive symptoms during MDR-TB treatment, and help in improving overall treatment outcomes. We recommend regular monitoring of mental health status by trained counsellors or clinical staff, using simple, validated and cost-effective tools.

Significance and costs of complex biopsychosocial health care needs in elderly people: results of a population-based study

OBJECTIVE

To improve health care for the elderly, a consideration of biopsychosocial health care needs may be of particular importance-especially because of the prevalence of multiple conditions, mental disorders, and social challenges facing elderly people. The aim of the study was to investigate significance and costs of biopsychosocial health care needs in elderly people.

METHODS

Data were derived from the 8-year follow-up of the ESTHER study-a German epidemiological study in the elderly population. A total of 3124 participants aged 57 to 84 years were visited at home by trained medical doctors. Biopsychosocial health care needs were assessed using the INTERMED for the Elderly (IM-E) interview. Health-related quality of life (HRQOL) was measured by the 12-Item Short-Form Health Survey, and psychosomatic burden was measured by the Patient Health Questionnaire.

RESULTS

The IM-E correlated with decreased mental (mental component score: r = -0.38, p < .0001) and physical HRQOL (physical component score: r = -0.45, p < .0001), increased depression severity (r = 0.53, p < .0001), and costs (R = 0.41, p < .0001). The proportion of the participants who had an IM-E score of at least 21 was 8.2%; according to previous studies, they were classified as complex patients (having complex biopsychosocial health care needs). Complex patients showed a highly reduced HRQOL compared with participants without complex health care needs (mental component score: 37.0 [10.8] versus 48.7 [8.8]; physical component score: 33.0 [9.1] versus 41.6 [9.5]). Mean health care costs per 3 months of complex patients were strongly increased (1651.1 &OV0556; [3192.2] versus 764.5 &OV0556; [1868.4]).

CONCLUSIONS

Complex biopsychosocial health care needs are strongly associated with adverse health outcomes in elderly people. It should be evaluated if interdisciplinary treatment plans would improve the health outcomes for complex patients.

Approach to the patient with multiple somatic symptoms

Primary care providers play a crucial role in the recognition and appropriate treatment of patients with multiple somatic complaints. Both the number of somatic symptoms and the persistence of symptoms are associated with co-occurring depression or anxiety disorders. It can be challenging to simultaneously address possible medical causes for physical symptoms while also considering an associated psychiatric diagnosis. In this article, strategies to improve the care and outcomes among these patients are described, including collaboration, education about the interaction between psychosocial stressors and somatic symptoms, regularly scheduled visits, focus on improving functional status, and evidence-based treatment of depression and anxiety.

Caregiving in heart failure: relationship quality is associated with caregiver benefit finding and caregiver burden

OBJECTIVE

To determine whether relationship quality is associated with caregiver benefit or burden and how depression influences these associations.

BACKGROUND

Caregivers influence outcomes of patients with heart failure (HF). Relationship quality, caregiver benefit and burden are key factors in the caregiving experience.

METHODS

Nineteen caregivers of HF outpatients completed measures of relationship quality, caregiver benefit, burden and depression. Associations were assessed using Pearson's correlations.

RESULTS

Relationship quality was positively associated with caregiver benefit (r = 0.45, P = 0.05) and negatively associated with burden (r = -0.80, P < 0.0001) and depression (r = -0.77, P = 0.0001). Relationship quality and burden remained associated after controlling for depression.

CONCLUSIONS

In this exploratory study, relationship quality was positively associated with caregiver benefit and negatively associated with burden. Future studies are needed to further understand these key caregiving factors, which may lead to opportunities to help caregivers see benefits and reduce burden.

Operating characteristics of PROMIS four-item depression and anxiety scales in primary care patients with chronic pain

OBJECTIVE

Depression and anxiety are prevalent in patients with chronic pain and adversely affect pain, quality of life, and treatment response. The purpose of this psychometric study was to determine the reliability and validity of the four-item Patient Reported Outcomes Measurement Information System (PROMIS) depression and anxiety scales in patients with chronic pain.

DESIGN

Secondary analysis of data from the Stepped Care to Optimize Pain care Effectiveness study, a randomized clinical trial of optimized analgesic therapy.

SETTING

Five primary care clinics at the Roudebush VA Medical Center (RVAMC) in Indianapolis, Indiana.

SUBJECTS

Two hundred forty-four primary care patients with chronic musculoskeletal pain.

METHODS

All patients completed the four-item depression and anxiety scales from the PROMIS 29-item profile, as well as several other validated psychological measures. The minimally important difference (MID) using the standard error of measurement (SEM) was calculated for each scale, and convergent validity was assessed by interscale correlations at baseline and 3 months. Operating characteristics of the PROMIS measures for detecting patients who had probable major depression or were anxiety-disorder screen-positive were calculated.

RESULTS

The PROMIS scales had good internal reliability, and the MID (as represented by two SEMs) was 2 points for the depression scale and 2.5 points for the anxiety scale. Convergent validity was supported by strong interscale correlations. The optimal screening cutpoint on the 4- to 20-point PROMIS scales appeared to be 8 for both the depression and anxiety scales.

CONCLUSIONS

The PROMIS four-item depression and anxiety scales are reasonable options as ultra-brief measures for screening in patients with chronic pain.

Predictors of postpartum depression

OBJECTIVE

To examine sociodemographic factors, pregnancy-associated psychosocial stress and depression, health risk behaviors, prepregnancy medical and psychiatric illness, pregnancy-related illnesses, and birth outcomes as risk factors for post-partum depression (PPD).

METHODS

A prospective cohort study screened women at 4 and 8 months of pregnancy and used hierarchical logistic regression analyses to examine predictors of PPD. The study sample include 1,423 pregnant women at a university-based high risk obstetrics clinic. A score of ≥10 on the Patient Health Questionnaire-9 (PHQ-9) indicated clinically significant depressive symptoms.

RESULTS

Compared with women without significant postpartum depressive symptoms, women with PPD were significantly younger (p<0.0001), more likely to be unemployed (p=0.04), had more pregnancy associated depressive symptoms (p<0.0001) and psychosocial stress (p<0.0001), were more likely to be smokers (p<0.0001), were more likely to be taking antidepressants (ADs) during pregnancy (p=0.002), were less likely to drink any alcohol during pregnancy (p=0.02), and were more likely to have prepregnancy medical illnesses, including diabetes (p=0.02) and neurologic conditions (p=0.02).

CONCLUSION

Specific sociodemographic and clinical risk factors for PPD were identified that could help physicians target depression case finding for pregnant women.

No significant difference in depression rate in employed and unemployed in a pair-matched study design

OBJECTIVES

The main objective of this study was to evaluate the differences of depression rate in employed and unemployed persons in the period of financial and economic crisis in Romania, in a pair-matched study design.

METHOD

The cross-sectional study uses a pair match design (395 pairs) of two groups of employed and unemployed persons. Other socio-demographic risk factors of depression (gender, age, marital status, residence, ethnicity, educational level, and profession) were controlled. The study was done in a historical period of economic crisis, 2009-2010. For the screening of depression we used the patient health questionnaire-9.

RESULTS

There were no statistical differences (p = 0.054) between the depression rates in the employed (17.98%) and unemployed (23.80%) samples. The depression rate in both groups was higher in females, age (51-55), marital status (divorced), living in the rural area, with a low level of education and poverty. Suicidal ideas are more frequent in men, employed persons with low level of education and in unemployed persons with medium level of education.

CONCLUSION

The exposure to short term unemployment status was not associated with change in depression rate in the period of financial and economic crisis in Romania, comparing with controls pair-matched. Unemployment status increases the depression rate only in vulnerable groups such as single or divorced women; and suicidal ideas were associated with the unemployment status (longer than 8 months) in men from rural area with medium level of education.

The patient health questionnaire-9: validation among patients with glaucoma

Background

Depression and anxiety are two common normal responses to a chronic disease such as glaucoma. This study analysed the measurement properties of the depression screening instrument - Patient Health Questionnaire-9 (PHQ-9) using Rasch analysis to determine if it can be used as a measure.

Methods

In this hospital-based cross-sectional study, the PHQ-9 was administered to primary glaucoma adults attending a glaucoma clinic of a tertiary eye care centre, South India. All patients underwent a comprehensive clinical evaluation. Patient demographics and sub-type of glaucoma were abstracted from the medical record. Rasch analysis was used to investigate the following properties of the PHQ-9: behaviour of the response categories, measurement precision (assessed using person separation reliability, PSR; minimum recommended value 0.80), unidimensionality (assessed using item fit [0.7–1.3] and principal components analysis of residuals), and targeting.

Results

198 patients (mean age ± standard deviation  = 59.83±12.34 years; 67% male) were included. The native PHQ-9 did not fit the Rasch model. The response categories showed disordered thresholds which became ordered after category reorganization. Measurement precision was below acceptable limits (0.62) and targeting was sub-optimal (−1.27 logits). Four items misfit that were deleted iteratively following which a set of five items fit the Rasch model. However measurement precision failed to improve and targeting worsened further (−1.62 logits).

Conclusions

The PHQ-9, in its present form, provides suboptimal assessment of depression in patients with glaucoma in India. Therefore, there is a need to develop a new depression instrument for our glaucoma population. A superior strategy would be to use the item bank for depression but this will also need to be validated in glaucoma patients before deciding its utility.

Emergency department-initiated palliative care for advanced cancer patients: protocol for a pilot randomized controlled trial

Background

For patients with advanced cancer, visits to the emergency department (ED) are common. Such patients present to the ED with a specific profile of palliative care needs, including burdensome symptoms such as pain, dyspnea, or vomiting that cannot be controlled in other settings and a lack of well-defined goals of care. The goals of this study are: i) to test the feasibility of recruiting, enrolling, and randomizing patients with serious illness in the ED; and ii) to evaluate the impact of ED-initiated palliative care on health care utilization, quality of life, and survival.

Methods/Design

This is a protocol for a single center parallel, two-arm randomized controlled trial in ED patients with metastatic solid tumors comparing ED-initiated palliative care referral to a control group receiving usual care. We plan to enroll 125 to 150 ED-advanced cancer patients at Mount Sinai Hospital in New York, USA, who meet the following criteria: i) pass a brief cognitive screen; ii) speak fluent English or Spanish; and iii) have never been seen by palliative care. We will use balanced block randomization in groups of 50 to assign patients to the intervention or control group after completion of a baseline questionnaire. All research staff performing assessment or analysis will be blinded to patient assignment. We will measure the impact of the palliative care intervention on the following outcomes: i) timing and rate of palliative care consultation; ii) quality of life and depression at 12 weeks, measured using the FACT-G and PHQ-9; iii) health care utilization; and iv) length of survival. The primary analysis will be based on intention-to-treat.

Discussion

This pilot randomized controlled trial will test the feasibility of recruiting, enrolling, and randomizing patients with advanced cancer in the ED, and provide a preliminary estimate of the impact of palliative care referral on health care utilization, quality of life, and survival.

Evaluation of a depression screening and treatment program in primary care for patients with diabetes mellitus: insights and future directions

PURPOSE

To evaluate a collaborative depression care program by assessing adherence to the program by internal medicine clinic (IMC) staff, and the program's effectiveness in treating depression in patients with diabetes mellitus. We also describe the rate of depression among patients with diabetes in the IMC.

DATA SOURCES

Data for this program were obtained from a de-identified disease registry and included 1312 outpatient IMC visits in adult patients with diabetes between March 2011 and September 2011.

CONCLUSIONS

Collaborative depression care results in high rates of screening for and identification of depression, high rates of antidepressant utilization, and improved depression scores; however, more focused interventions are needed to improve diabetes outcomes in patients with depression and diabetes.

IMPLICATIONS FOR PRACTICE

The results indicate that the multidisciplinary IMC staff can work together with patients to identify and monitor depression within primary care. This study provides valuable information about models of depression care that can be implemented and evaluated in a clinical setting.

Intervention to reduce excessive alcohol consumption and improve comorbidity outcomes in hypertensive or depressed primary care patients: two parallel cluster randomized feasibility trials

BACKGROUND

Many primary care patients with raised blood pressure or depression drink potentially hazardous levels of alcohol. Brief interventions (BI) to reduce alcohol consumption may improve comorbid conditions and reduce the risk of future alcohol problems. However, research has not established their effectiveness in this patient population. This study aimed to establish the feasibility of definitive trials of BI to reduce excessive drinking in primary care patients with hypertension or mild to moderate depression.

METHODS

Thirteen general practices in North East England were randomized to the intervention or control arm of one of two parallel pilot trials. Adult patients drinking excessively and diagnosed with hypertension or mild-to-moderate depression received the Alcohol Use Disorders Identification Test (AUDIT) by postal survey. Consenting respondents scoring more than 7 on AUDIT (score range 0 to 40) received brief alcohol consumption advice plus an information leaflet (intervention) or an information leaflet alone (control) with follow-up at six months. Measurements included the numbers of patients eligible, recruited, and retained, and the AUDIT score and systolic/diastolic blood pressure of each patient or the nine-item Patient Health Questionnaire (PHQ-9) score. Acceptability was assessed via practitioner feedback and patient willingness to be screened, recruited, and retained at follow-up.

RESULTS

In the hypertension trial, 1709 of 33,813 adult patients (5.1%) were eligible and were surveyed. Among the eligible patients, 468 (27.4%) returned questionnaires; 166 (9.6% of those surveyed) screened positively on AUDIT and 83 (4.8% of those surveyed) were recruited (50.0% of positive screens). Sixty-seven cases (80.7% of recruited patients) completed follow-up at six months. In the depression trial, 1,044 of 73,146 adult patients (1.4%) were eligible and surveyed. Among these eligible patients, 215 (20.6%) responded; 104 (10.0% of those surveyed) screened positively on AUDIT and 29 (2.8% of those surveyed) were recruited (27.9% of positive screens). Nineteen cases (65.5% of recruited patients) completed follow-up at six months.

CONCLUSIONS

Recruitment and retention rates were higher in the hypertension trial than in the depression trial. A full brief intervention trial appears feasible for primary care patients with hypertension who drink excessively. High AUDIT scores in the depression trial suggest the importance of alcohol intervention in this group. However, future work may require alternative screening and measurement procedures.

Novel Association of Rectal Evacuation Disorder and Rumination Syndrome: Diagnosis, Co-morbidities and Treatment

BACKGROUND

Patients with disorders of gastrointestinal function may undergo unnecessary treatment if misdiagnosed as motility disorders.

OBJECTIVE

To report on clinical features, medical, surgical and psychiatric co-morbidities, and prior treatments of a patient cohort diagnosed concurrently with non-psychogenic rumination syndrome and pelvic floor dysfunction (also termed rectal evacuation disorder).

METHODS

From a consecutive series (1994-2013) of 438 outpatients with rectal evacuation disorders in the practice of a single gastroenterologist at a tertiary care center, 57 adolescents or adults were diagnosed with concomitant rumination syndrome. All underwent formal psychological assessment or completed validated questionnaires.

RESULTS

All 57 patients (95% female) fulfilled Rome III criteria for rumination syndrome; rectal evacuation disorder was confirmed by testing of anal sphincter pressures and rectal balloon evacuation. Prior to diagnosis, most patients underwent multiple medical and surgical treatments (gastrostomy, gastric fundoplication, other gastric surgery, ileostomy, colectomy) for their symptoms. Psychological co-morbidity was identified in 93% of patients. Patients were managed predominantly with psychological and behavioral approaches: diaphragmatic breathing for rumination and biofeedback retraining for pelvic floor dysfunction.

CONCLUSIONS

Awareness of concomitant rectal evacuation disorder and rumination syndrome and prompt identification of psychological co-morbidity are keys to instituting behavioral and psychological methods to avoid unnecessary treatment.

Comparison of complementary and alternative medicine with conventional mind-body therapies for chronic back pain: protocol for the Mind-body Approaches to Pain (MAP) randomized controlled trial

BACKGROUND

The self-reported health and functional status of persons with back pain in the United States have declined in recent years, despite greatly increased medical expenditures due to this problem. Although patient psychosocial factors such as pain-related beliefs, thoughts and coping behaviors have been demonstrated to affect how well patients respond to treatments for back pain, few patients receive treatments that address these factors. Cognitive-behavioral therapy (CBT), which addresses psychosocial factors, has been found to be effective for back pain, but access to qualified therapists is limited. Another treatment option with potential for addressing psychosocial issues, mindfulness-based stress reduction (MBSR), is increasingly available. MBSR has been found to be helpful for various mental and physical conditions, but it has not been well-studied for application with chronic back pain patients. In this trial, we will seek to determine whether MBSR is an effective and cost-effective treatment option for persons with chronic back pain, compare its effectiveness and cost-effectiveness compared with CBT and explore the psychosocial variables that may mediate the effects of MBSR and CBT on patient outcomes.

METHODS/DESIGN

In this trial, we will randomize 397 adults with nonspecific chronic back pain to CBT, MBSR or usual care arms (99 per group). Both interventions will consist of eight weekly 2-hour group sessions supplemented by home practice. The MBSR protocol also includes an optional 6-hour retreat. Interviewers masked to treatment assignments will assess outcomes 5, 10, 26 and 52 weeks postrandomization. The primary outcomes will be pain-related functional limitations (based on the Roland Disability Questionnaire) and symptom bothersomeness (rated on a 0 to 10 numerical rating scale) at 26 weeks.

DISCUSSION

If MBSR is found to be an effective and cost-effective treatment option for patients with chronic back pain, it will become a valuable addition to the limited treatment options available to patients with significant psychosocial contributors to their pain.

A mixed methods exploration of family members'/friends' roles in a self-care intervention for depressive symptoms

OBJECTIVES

The aims of this exploratory study were to examine the: (1) family and friend (F/F) support patients reported receiving and F/F reported providing to patients while participating in a self-care intervention (SCI) for depressive symptoms and (2) associations between different types of F/F support and patients' use of the self-care tools in the SCI.

METHODS

Fifty-seven patients aged 40 + participating in an uncontrolled feasibility study of an SCI, completed structured telephone interviews about the support they received from F/F while participating in the SCI. Eighteen F/F completed questionnaires on the support they provided to patients during the SCI. Seven F/F participated in a post-study qualitative interview on their involvement in the SCI.

RESULTS

About 35% of patients reported receiving F/F support with the SCI. Patients' use of the behavioral tools was positively associated with patients' report of F/F support, and with F/F's report of instrumental support provided. F/F reported uncertainty about the type of support they should offer to patients in the SCI.

DISCUSSION

F/F involvement in SCIs for depressive symptoms may be helpful to patients and may foster adherence to these interventions. More research is warranted on the nature of such involvement from the perspective of patients and F/F.

The work and social adjustment scale: reliability, sensitivity and value

OBJECTIVE

To investigate the psychometric properties of the Work and Social Adjustment Scale (WSAS) as an outcome measure for the Improving Access to Psychological Therapy programme, assessing its value as an addition to the Patient Health (PHQ-9) and Generalised Anxiety Disorder questionnaires (GAD-7). Little research has investigated these properties to date.

METHODS

Reliability and responsiveness to change were assessed using data from 4,835 patients. Principal components analysis was used to determine whether the WSAS measures a factor distinct from the PHQ-9 and GAD-7.

RESULTS

The WSAS measures a distinct social functioning factor, has high internal reliability, and is sensitive to treatment effects.

CONCLUSIONS

The WSAS, PHQ-9 and GAD-7 perform comparably on measures of reliability and sensitivity. The WSAS also measures a distinct social functioning component suggesting it has potential as an additional outcome measure.

Evaluation of the role of training in the implementation of a depression screening and treatment protocol in 2 academic outpatient internal medicine clinics utilizing the electronic medical record

Systematic approaches to depression identification and management are effective though not consistently implemented. The research team implemented a depression protocol, preceded by training, in 2 faculty-resident practices. Medical assistants used the Patient Health Questionnaire (PHQ)-2 for initial screening; providers performed the PHQ-9. These were documented in the electronic medical record. Logistic regression was performed to assess the association of provider type, clinic site, and training attendance with documentation of PHQ-9 after positive PHQ-2s, and with repeat PHQ-9s after positive PHQ-9s. In logistic regression analysis, training attendance was positively associated with documentation of PHQ-9 after a positive PHQ-2 (odds ratio [OR] = 2.4 [confidence interval (CI) = 1.3-4.3]) and repeated documentation of a PHQ-9 after a positive PHQ-9 (OR = 2.5 [CI = 1.1-5.3]). This study describes the successful implementation of a stepped-care approach to depression care. The positive association of training with compliance with protocol procedures indicates the importance of training in the implementation of practice change.

The impact of depression and somatic symptoms on treatment outcomes in patients with chronic prostatitis/chronic pelvic pain syndrome: a preliminary study in a naturalistic treatment setting

AIM

The aim of this study was to evaluate the impact of depression and somatic symptoms on treatment outcomes in Korean male patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) attending a routine clinical practice.

METHODS

This was a 12-week prospective observational study (n = 80). The Korean version of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) to measure the severity of CP/CPPS, the Korean version of the Patient Health Questionnaire-9 (PHQ-9) to assess depression, the Korean version of the Patient Health Questionnaire-15 (PHQ-15) to evaluate somatisation and the Korean version of the EuroQol Questionnaire-5 Dimensions (EQ-5D), specifically the EQ-5D utility index and the EQ-5D visual analogue scale (EQ-5D VAS), to assess quality of life, were utilised and given at baseline and week 12. The primary and secondary end-points in this study were changes in the NIH-CPSI total score from baseline to week 12 according to depression and somatisation.

RESULTS

The change in NIH-CPSI total score was significantly higher in those without depression than in those with depression (p = 0.003), with a magnitude of difference of 2.8. The responder rate (a ≥ 4 point decrease in NIH-CPSI total score from baseline) was significantly higher in those without depression (42.9%) than in those with depression (17.2%, p = 0.023). However, significant differences were not observed between the two groups in the other outcome measures or in all study outcomes between subjects with or without somatisation. A logistic regression analysis revealed that the presence or absence of depression may be a principal predictor of response to treatment.

CONCLUSION

These preliminary results indicate that depression may have a negative impact on treatment outcome and is a likely predictor of response to treatment in patients with CP/CPPS. However, additional studies with adequate power and improved design are necessary to further support the present findings.

Patients from areas of high deprivation entered the service with more severe depression (M = 15.47, SD = 6.75), compared with patients from areas of low (M = 13.20, SD = 6.75) and medium (M = 14.44, SD = 6.64) deprivation. Patients in low, medium and high deprivation areas attained similar changes in depression score (ΔPHQ9: M = -6.60, SD = 6.41). Similar proportions of patients achieved the key performance indicator across initiative phase and deprivation categories.

CONCLUSIONS

QI methods improved access to mental health services; this paper finds no evidence for differences in clinical outcomes in patients, regardless of level of deprivation, interpreted as no evidence of inequity in the service with respect to this outcome.

Comparing CESD-10, PHQ-9, and PROMIS depression instruments in individuals with multiple sclerosis

PURPOSE

This study evaluated psychometric properties of the Patient Health Questionnaire-9 (PHQ-9), the Center for Epidemiological Studies Depression Scale-10 (CESD-10), and the 8-item PROMIS Depression Short Form (PROMIS-D-8; 8b short form) in a sample of individuals living with multiple sclerosis (MS).

RESEARCH METHOD

Data were collected by a self-reported mailed survey of a community sample of people living with MS (n = 455). Factor structure, interitem reliability, convergent/discriminant validity and assignment to categories of depression severity were examined.

RESULTS

A 1-factor, confirmatory factor analytic model had adequate fit for all instruments. Scores on the depression scales were more highly correlated with one another than with scores on measures of pain, sleep disturbance, and fatigue. The CESD-10 categorized about 37% of participants as having significant depressive symptoms. At least moderate depression was indicated for 24% of participants by PHQ-9. PROMIS-D-8 identified 19% of participants as having at least moderate depressive symptoms and about 7% having at least moderately severe depression. None of the examined scales had ceiling effects, but the PROMIS-D-8 had a floor effect.

CONCLUSIONS

Overall, scores on all 3 scales demonstrated essential unidimensionality and had acceptable interitem reliability and convergent/discriminant validity. Researchers and clinicians can choose any of these scales to measure depressive symptoms in individuals living with MS. The PHQ-9 offers validated cutoff scores for diagnosing clinical depression. The PROMIS-D-8 measure minimizes the impact of somatic features on the assessment of depression and allows for flexible administration, including Computerize Adaptive Testing (CAT). The CESD-10 measures 2 aspects of depression, depressed mood and lack of positive affect, while still providing an interpretable total score.

Risk factors for depression in patients undergoing hematopoietic cell transplantation

Despite the prevalence and known adverse impacts of depression after hematopoietic cell transplantation (HCT), little is known about the trajectory of depression occurring after HCT, or which pretransplantation risk factors might help predict new or worsening post-HCT depression. This secondary analysis evaluated the relationships between pre-HCT patient-reported outcomes and demographic characteristics and post-HCT depression. A total of 228 adult HCT patients were evaluated pre-HCT (T1) and again at 6 to 7 weeks post-HCT (T2), using touch-screen computers in the transplantation clinic during participation in a larger trial. Measures evaluated included the Symptom Distress Scale, the EORTC QLQ-C30 for quality of life, a single-item pain intensity question, and the Patient Health Questionnaire 9 for measurement of depression. At T1, rates of depression were quite low, with only 6% of participants reporting moderate or higher depression. At T2, however, the prevalence of moderate or higher depression was 31%. We observed a strong linear relationship in PHQ-9 scores between T1 and T2 (P < .0001). Depression score at T1 was a significant predictor of depression score at T2 (P = .03), as was poorer emotional function at T1 (P < .01). Our results indicate that post-HCT depression is common, even in patients with a low pre-HCT depression score. Frequent screening for symptoms of depression at critical time points, including 6 to 7 weeks post-HCT, are needed in this population, followed by referrals to supportive care as appropriate.

Patient activation, depression and quality of life

OBJECTIVE

"Patient activation" describes the extent to which individuals manage their own healthcare. This study evaluated the association of patient activation, depressive symptoms and quality of life in a primary care setting.

METHODS

278 patients who visited two primary care clinics were interviewed in the waiting room before their appointment or by telephone. Study participants completed the Patient Activation Measure (PAM), Patient Health Questionnaire-9 (PHQ-9) and Short Form-12 Health Survey (SF-12). Physicians assessed each participant's depression status immediately after the visit.

RESULTS

PAM scores correlated negatively with PHQ-9 (r=-0.35, p<0.0001) and positively with total SF-12 score (r=0.39, p<0.0001). Increased participant involvement by one-level increments on the PAM was predicted by their being in the 55 to 74-year age group and higher total SF-12 quartiles. Almost half of those scoring ≥10 on PHQ-9 were not considered depressed by their physician (false negatives, i.e. "hidden depression").

CONCLUSION

In primary care settings, PAM is easily administered and useful for general patients and for those with depressive symptoms.

PRACTICE IMPLICATIONS

Assessing patient activation will enable caregivers to monitor levels of self-care (activation) and potential adherence to health behavior recommendations. PHQ-9 screening could increase awareness of "hidden depression" in the primary care setting.

Combining cognitive-behavioral therapy and milnacipran for fibromyalgia: a feasibility randomized-controlled trial

OBJECTIVES

To evaluate the feasibility of a randomized-controlled trial and to obtain estimates of the effects of combined cognitive-behavioral therapy (CBT) and milnacipran for the treatment of fibromyalgia.

METHODS

Fifty-eight patients with fibromyalgia were randomized to 1 of the 3 treatment arms: (1) combination therapy (n = 20); (2) milnacipran+education (n = 19); and (3) placebo+CBT (n = 19). Patients received either milnacipran (100 mg/d) or placebo. Patients also received 8 sessions of phone-delivered CBT or educational instructions, but only from baseline to week 9. Assessments were conducted at baseline, week 9, and 21. The primary endpoints were baseline to week 21 changes in weekly average pain intensity and physical function (SF-36 physical function scale).

RESULTS

Compared with milnacipran, combination therapy demonstrated a moderate effect on improving SF-36 physical function (SE = 9.42 [5.48], P = 0.09, effect size = 0.60) and in reducing weekly average pain intensity (mean difference [SE] = -1.18 [0.62], P = 0.07, effect size = 0.67). Compared with milnacipran, CBT had a moderate to large effect in improving SF-36 physical function (mean difference [SE] = 11.0 [5.66], P = 0.06, effect size = 0.70). Despite the presence of concomitant centrally acting therapies, dropout rate was lower than anticipated (15% at week 21). Importantly, at least 6 out of the 8 phone-based therapy sessions were successfully completed by 89% of the patients; and adherence to the treatment protocols was > 95%.

CONCLUSIONS

In this pilot study, a therapeutic approach that combines phone-based CBT and milnacipran was feasible and acceptable. Moreover, the preliminary data supports conducting a fully powered randomized-controlled trial.

Assessing depression in cardiac patients: what measures should be considered?

It is highly recommended to promptly assess depression in heart disease patients as it represents a crucial risk factor which may result in premature deaths following acute cardiac events and a more severe psychopathology, even in cases of subsequent nonfatal cardiac events. Patients and professionals often underestimate or misjudge depressive symptomatology as cardiac symptoms; hence, quick, reliable, and early mood changes assessments are warranted. Failing to detect depressive signals may have detrimental effects on these patients' wellbeing and full recovery. Choosing gold-standard depression investigations in cardiac patients that fit a hospitalised cardiac setting well is fundamental. This paper will examine eight well established tools following Italian and international guidelines on mood disorders diagnosis in cardiac patients: the Hospital Anxiety and Depression Scale (HADS), the Cognitive Behavioural Assessment Hospital Form (CBA-H), the Beck Depression Inventory (BDI), the two and nine-item Patient Health Questionnaire (PHQ-2, PHQ-9), the Depression Interview and Structured Hamilton (DISH), the Hamilton Rating Scale for Depression (HAM-D/HRSD), and the Composite International Diagnostic Interview (CIDI). Though their strengths and weaknesses may appear to be homogeneous, the BDI-II and the PHQ are more efficient towards an early depression assessment within cardiac hospitalised patients.

Cost and outcome of behavioural activation versus cognitive behaviour therapy for depression (COBRA): study protocol for a randomised controlled trial

BACKGROUND

Cognitive behaviour therapy (CBT) is an effective treatment for depression. However, CBT is a complex therapy that requires highly trained and qualified practitioners, and its scalability is therefore limited by the costs of training and employing sufficient therapists to meet demand. Behavioural activation (BA) is a psychological treatment for depression that may be an effective alternative to CBT and, because it is simpler, might also be delivered by less highly trained and specialised mental health workers.

METHODS/DESIGN

COBRA is a two-arm, non-inferiority, patient-level randomised controlled trial, including clinical, economic, and process evaluations comparing CBT delivered by highly trained professional therapists to BA delivered by junior professional or para-professional mental health workers to establish whether the clinical effectiveness of BA is non-inferior to CBT and if BA is cost effective compared to CBT. Four hundred and forty patients with major depressive disorder will be recruited through screening in primary care. We will analyse for non-inferiority in per-protocol and intention-to-treat populations. Our primary outcome will be severity of depression symptoms (Patient Health Questionnaire-9) at 12 months follow-up. Secondary outcomes will be clinically significant change and severity of depression at 18 months, and anxiety (General Anxiety Disorder-7 questionnaire) and health-related quality of life (Short-Form Health Survey-36) at 12 and 18 months. Our economic evaluation will take the United Kingdom National Health Service/Personal Social Services perspective to include costs of the interventions, health and social care services used, plus productivity losses. Cost-effectiveness will explored in terms of quality-adjusted life years using the EuroQol-5D measure of health-related quality of life.

DISCUSSION

The clinical and economic outcomes of this trial will provide the evidence to help policy makers, clinicians and guideline developers decide on the merits of including BA as a first-line treatment of depression.

Integrated depression management: a proposed trial of a new model of care in a low vision rehabilitation setting

PURPOSE

Depression is a common problem among people with visual impairment and contributes to functional decline. This article presents a study protocol to evaluate a new model of care for those patients with depressive symptoms in which psychological treatment is integrated into low vision rehabilitation services. Low vision staff will be trained to deliver "problem solving therapy for primary care" (PST-PC), an effective psychological treatment developed specifically for delivery by non-mental health care staff. PST-PC is delivered in 8 weekly telephone sessions of 30-45 minutes duration and 4 monthly maintenance sessions. We predict this new integrated model of care will significantly reduce depressive symptoms and improve the quality of life for people with visual impairment.

METHODS AND DESIGN

A randomized controlled trial of PST-PC will be implemented nationally across low vision rehabilitation services provided by Vision Australia. Clients who screen positive for depressive symptoms and meet study criteria will be randomized to receive PST-PC or usual care, consisting of a referral to their general practitioner for more detailed assessment and treatment. Outcome measures include depressive symptoms and behaviors, quality of life, coping and psychological adjustment to visual impairment. Masked assessments will take place pre- and post-intervention as well as at 6- and 12-month follow-up.

CONCLUSION

We anticipate that this innovative service delivery model will lead to sustained improvements in clients' quality of life in a cost effective manner and provide an innovative service delivery model suitable for other health care areas in which depression is co-morbid.

Depression as a correlate of functional status of community-dwelling older adults: utilizing a short-version of 5-item Geriatric Depression Scale as a screening tool

Depression has been known to be associated with functional limitations in elderly populations and screening is an effective preventive approach. The purpose of this study was to examine the contribution of depression in explaining the functional status of community-dwelling older adults and to explore the utility of a short version 5-item Geriatric Depression Scale (GDS-5) as a screening tool.

DESIGN

Cross-sectional survey Settings: Six hospitals and communities served by home-delivery meal programs Participants: 529 individuals aged 60 years and older.

MEASUREMENTS

Using structured survey questionnaires, key variables including demographics, depression status, and two domains of functional status assessed by basic Activities of Daily Living (ADL) /Instrumental ADL (IADL) and mini-mental status (MMSE) were collected. To determine the unique contribution of depression in explaining functional status of participating older adults, hierarchical multiple regression was conducted.

RESULTS

The model explained 18 % of the total variance in physical function and 21 % of the total variance in cognitive function. Race/ethnicity and depression were significant predictors of functional status. In particular, entry of the depression variable resulted in a significant R square change of 7%, accounting for a unique portion of the ADL/IADL variance. In terms of cognitive function measured by MMSE, entry of the depression variable showed a small, but significant change. Older adults who were ethnic minorities and had depression were significantly more likely to report poor perceived physical and cognitive function. Hierarchical multiple regressions revealed that some personal factors such as age, education, race/ethnicity contributed to the explanatory model, and depressive symptoms significantly explained additional variance. GDS-5 was less reliable (Cronbach's alpha= 0.5) to assess depressive symptoms in this study.

CONCLUSION

Depression was a significant contributing factor to functional limitations of older adults. A short 5-item version of the GDS could be used to screen older adults, but two-tiered GDS-5/15 would be better alternative tool.

Depression Correlates with Increased Plasma Levels of Inflammatory Cytokines and a Dysregulated Oxidant/Antioxidant Balance in HIV-1-Infected Subjects Undergoing Antiretroviral Therapy

OBJECTIVE

Depression is the most common psychiatric diagnosis in the HIV/AIDS population and represents a risk factor for disease progression. Since HIV-1 infection is characterized by immunologic and metabolic disturbances, we want to study the effects of depression on different components related to pro-inflammatory and oxidative stress markers. We hypothesize that depression will lead to increased pro-inflammatory cytokine levels and altered antioxidant/oxidant balance.

METHODS

We included males and females who were ≥21 years of age, whose HIV-1 sero-status was confirmed by Western Blot, and who were currently undergoing antiretroviral treatment. Patients completed the participation consent form, a socio-demographic survey, and the Patient Health Questionnaire-9 (PHQ-9) for depression assessment. We isolated the plasma from participants' blood samples for viral load analysis (RT-PCR), T-cell counts (flow cytometry), and hematological parameters. A cytokine magnetic bead panel was used to measure interleukin-15 (IL-15), interferon gamma-induced protein 10 (IP-10), IL-12 and granulocyte colony-stimulating factor (G-CSF) levels. We also performed assays to determine the antioxidant activity of superoxide dismutase (SOD) and catalase and to measure the lipid peroxidation levels using malondialdehyde (MDA) and 8-isoprostane assays. Statistical comparisons and correlations at 5% level of significance were determined.

RESULTS

Our results show that subjects with mild/moderate to severe depression as assessed by PHQ-9 had a significantly decreased adherence to anti-retroviral treatment. Subjects with depression also had significantly lower levels of white blood cells (WBC) and platelets (PLT) than did the non-depressed group. The HIV⁺ subjects with depression had increased levels of IL-15, IP-10, IL-12 p40/p70 and G-CSF compared to their non-depressed counterparts. The latter had increased MDA and 8-isoprostane levels.

CONCLUSIONS

Our results suggest that HIV⁺ subjects with depressive symptoms have higher levels of inflammation and altered oxidant/antioxidant balance. Although the groups were small, this study strengthens the hypothesis that alterations in cytokines are associated with the mechanisms underlying depression symptoms.

Perceived discrimination and its associations with mental health and substance use among Asian American and Pacific Islander undergraduate and graduate students

OBJECTIVES

Racial discrimination experiences can negatively affect health. This study examined perceived discrimination and its relationship with mental health and substance use among Asian American and Pacific Islander (API) undergraduate and graduate students.

PARTICIPANTS

A total of 113 API students aged 18-35 completed the study during February-June, 2011.

METHODS

The authors conducted a cross-sectional, anonymous survey online. Dependent variables included mental health (depressive, anxiety, and somatic symptoms) and substance use (alcohol problems, use of tobacco, marijuana or hashish, and other illegal drugs).

RESULTS

Students' perceived discrimination were significantly, positively associated with depressive, anxiety, and somatic symptoms, but not with substance use. Ethnic identity moderated the relationship between perceived discrimination and somatic symptoms, but not depressive or anxiety symptoms.

CONCLUSIONS

These findings suggested the negative effect of racial discrimination on API students' mental health. The buffering effect of ethnic identity may increase resilience in these students when they face racial discrimination.

Rimonabant effects on anxiety induced by simulated public speaking in healthy humans: a preliminary report

OBJECTIVE

We investigated the hypothesis that rimonabant, a cannabinoid antagonist/inverse agonist, would increase anxiety in healthy subjects during a simulation of the public speaking test.

METHODS

Participants were randomly allocated to receive oral placebo or 90 mg rimonabant in a double-blind design. Subjective effects were measured by Visual Analogue Mood Scale. Physiological parameters, namely arterial blood pressure and heart rate, also were monitored.

RESULTS

Twelve participants received oral placebo and 12 received 90 mg rimonabant. Rimonabant increased self-reported anxiety levels during the anticipatory speech and performance phase compared with placebo. Interestingly, rimonabant did not modulate anxiety prestress and was not associated with sedation, cognitive impairment, discomfort, or blood pressure changes.

CONCLUSIONS

Cannabinoid-1 antagonism magnifies the responses to an anxiogenic stimulus without interfering with the prestress phase. These data suggest that the endocannabinoid system may work on-demand to counteract the consequences of anxiogenic stimuli in healthy humans.

PTSD symptom dimensions and their relationship to functioning in World Trade Center responders

Post-traumatic stress disorder (PTSD) symptoms are common among responders to the 9/11 attacks on the World Trade Center and can lead to impairment, yet it is unclear which symptom dimensions are responsible for poorer functioning. Moreover, how best to classify PTSD symptoms remains a topic of controversy. The present study tested competing models of PTSD dimensions and then assessed which were most strongly associated with social/occupational impairment, depression, and alcohol abuse. World Trade Center responders (n=954) enrolled in the Long Island site of the World Trade Center Health Program between 2005 and 2006 were administered standard self-report measures. Confirmatory factor analysis confirmed the superiority of four-factor models of PTSD over the DSM-IV three-factor model. In selecting between four-factor models, evidence was mixed, but some support emerged for a broad dysphoria dimension mapping closely onto depression and contributing strongly to functional impairment. This study confirmed in a new population the need to revise PTSD symptom classification to reflect four dimensions, but raises questions about how symptoms are categorized. Results suggest that targeted treatment of symptoms may provide the most benefit, and that treatment of dysphoria-related symptoms in disaster relief workers may have the most benefit for social and occupational functioning.

Factors associated with change in sexual transmission risk behavior over 3 years among HIV-infected patients in Tanzania

Background

The reduction of HIV transmission risk behaviors among those infected with HIV remains a major global health priority. Psychosocial characteristics have proven to be important correlates of sexual transmission risk behaviors in high-income countries, but little attention has focused on the influence of psychosocial and psychological factors on sexual transmission risk behaviors in African cohorts.

Methodology and Principal Findings

The CHAT Study enrolled a representative sample of 499 HIV-infected patients in established HIV care and 267 newly diagnosed HIV-infected individuals from the Kilimanjaro Region of Tanzania. Participants completed in-person interviews every 6 months for 3 years. Using logistic random effects models to account for repeated observations, we assessed sociodemographic, physical health, and psychosocial predictors of self-reported unprotected sexual intercourse. Among established patients, the proportion reporting any recent unprotected sex was stable, ranging between 6–13% over 3 years. Among newly diagnosed patients, the proportion reporting any unprotected sex dropped from 43% at baseline to 11–21% at 6–36 months. In multivariable models, higher odds of reported unprotected sex was associated with female gender, younger age, being married, better physical health, and greater post-traumatic stress symptoms. In addition, within-individual changes in post-traumatic stress over time coincided with increases in unprotected sex.

Conclusions and Significance

Changes in post-traumatic stress symptomatology were associated with changes in sexual transmission risk behaviors in this sample of HIV-infected adults in Tanzania, suggesting the importance of investing in appropriate mental health screening and intervention services for HIV-infected patients, both to improve mental health and to support secondary prevention efforts.

Feasibility and acceptability of a collaborative care intervention to improve symptoms and quality of life in chronic heart failure: mixed methods pilot trial

BACKGROUND

People with chronic heart failure (HF) suffer from numerous symptoms that worsen quality of life. The CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) intervention was designed to improve symptoms and quality of life by integrating palliative and psychosocial care into chronic care.

OBJECTIVE

Our aim was to determine the feasibility and acceptability of CASA and identify necessary improvements.

METHODS

We conducted a prospective mixed-methods pilot trial. The CASA intervention included (1) nurse phone visits involving structured symptom assessments and guidelines to alleviate breathlessness, fatigue, pain, or depression; (2) structured phone counseling targeting adjustment to illness and depression if present; and (3) weekly team meetings with a palliative care specialist, cardiologist, and primary care physician focused on medical recommendations to primary care providers (PCPs, physician or nurse practioners) to improve symptoms. Study subjects were outpatients with chronic HF from a Veteran's Affairs hospital (n=15) and a university hospital (n=2). Measurements included feasibility (cohort retention rate, medical recommendation implementation rate, missing data, quality of care) and acceptability (an end-of-study semi-structured participant interview).

RESULTS

Participants were male with a median age of 63 years. One withdrew early and there were <5% missing data. Overall, 85% of 87 collaborative care team medical recommendations were implemented. All participants who screened positive for depression were either treated for depression or thought to not have a depressive disorder. In the qualitative interviews, patients reported a positive experience and provided several constructive critiques.

CONCLUSIONS

The CASA intervention was feasible based on participant enrollment, cohort retention, implementation of medical recommendations, minimal missing data, and acceptability. Several intervention changes were made based on participant feedback.

Effect of communication skills training for residents and nurse practitioners on quality of communication with patients with serious illness: a randomized trial

IMPORTANCE

Communication about end-of-life care is a core clinical skill. Simulation-based training improves skill acquisition, but effects on patient-reported outcomes are unknown.

OBJECTIVE

To assess the effects of a communication skills intervention for internal medicine and nurse practitioner trainees on patient- and family-reported outcomes.

DESIGN, SETTING, AND PARTICIPANTS

Randomized trial conducted with 391 internal medicine and 81 nurse practitioner trainees between 2007 and 2013 at the University of Washington and Medical University of South Carolina.

INTERVENTION

Participants were randomized to an 8-session, simulation-based, communication skills intervention (N = 232) or usual education (N = 240).

MAIN OUTCOMES AND MEASURES

Primary outcome was patient-reported quality of communication (QOC; mean rating of 17 items rated from 0-10, with 0 = poor and 10 = perfect). Secondary outcomes were patient-reported quality of end-of-life care (QEOLC; mean rating of 26 items rated from 0-10) and depressive symptoms (assessed using the 8-item Personal Health Questionnaire [PHQ-8]; range, 0-24, higher scores worse) and family-reported QOC and QEOLC. Analyses were clustered by trainee.

RESULTS

There were 1866 patient ratings (44% response) and 936 family ratings (68% response). The intervention was not associated with significant changes in QOC or QEOLC. Mean values for postintervention patient QOC and QEOLC were 6.5 (95% CI, 6.2 to 6.8) and 8.3 (95% CI, 8.1 to 8.5) respectively, compared with 6.3 (95% CI, 6.2 to 6.5) and 8.3 (95% CI, 8.1 to 8.4) for control conditions. After adjustment, comparing intervention with control, there was no significant difference in the QOC score for patients (difference, 0.4 points [95% CI, -0.1 to 0.9]; P = .15) or families (difference, 0.1 [95% CI, -0.8 to 1.0]; P = .81). There was no significant difference in QEOLC score for patients (difference, 0.3 points [95% CI, -0.3 to 0.8]; P = .34) or families (difference, 0.1 [95% CI, -0.7 to 0.8]; P = .88). The intervention was associated with significantly increased depression scores among patients of postintervention trainees (mean score, 10.0 [95% CI, 9.1 to 10.8], compared with 8.8 [95% CI, 8.4 to 9.2]) for control conditions; adjusted model showed an intervention effect of 2.2 (95% CI, 0.6 to 3.8; P = .006).

CONCLUSIONS AND RELEVANCE

Among internal medicine and nurse practitioner trainees, simulation-based communication training compared with usual education did not improve quality of communication about end-of-life care or quality of end-of-life care but was associated with a small increase in patients' depressive symptoms. These findings raise questions about skills transfer from simulation training to actual patient care and the adequacy of communication skills assessment.

Psychometric properties of an automated telephone-based PHQ-9

OBJECTIVE

This study aims to evaluate the psychometric properties of an automated version of the Patient Health Questionnaire-9 (PHQ-9) to further facilitate its use in primary care. We automated the PHQ-9 using a computer telephony modality (interactive voice response system) called telephone-linked communication (TLC).

SUBJECTS AND METHODS

Eighty subjects were divided into four depression categories: none, mild, moderate, and severe. The automated questionnaire, TLC-PHQ-9, was administered to all subjects five times over a 3-month period, at intervals of 0 (T1), 1, 3, 4, and 4 (T5) weeks, respectively. The Inventory of Depressive Symptomatology (IDS) was administered (paper-and-pencil) at T1 and T5. We examined (1) reliability, (2) validity, (3) sensitivity and specificity, and (4) sensitivity to change.

RESULTS

(1) Test-retest reliability showed substantial agreement between T1 and T2, with a weighted kappa of 0.76 (95% confidence interval [CI] 0.67-0.85). Cronbach's coefficient alpha values ranged from 0.913 to 0.918 for each TLC-PHQ-9 assessment. (2) The weighted kappa of 0.78 (95% CI 0.70-0.87) for T1 and 0.73 (95% CI 0.63-0.83) for T5 showed strong agreement between TLC-PHQ-9 and IDS in all depression categories. (3) TLC-PHQ-9 demonstrated good sensitivity (82.4%) and very good specificity (90.7%) for moderate-plus depression and poorer sensitivity (54.2%) but very good specificity (97.8%) for severe-plus depression. (4) The weighted kappa of 0.53 (95% CI 0.35-0.70) indicated moderate agreement between TLC-PHQ-9 and IDS.

CONCLUSIONS

An automated telephony administration of the PHQ-9 appears to be a valid and reliable tool for monitoring depression symptoms and has strong fidelity across patients.

Total blood mercury levels and depression among adults in the United States: National Health and Nutrition Examination Survey 2005-2008

BACKGROUND

Mercury is a neurotoxicant linked with psychiatric symptoms at high levels of exposure. However, it is unclear whether an association is present at the low exposure levels in the US adult population.

MATERIALS AND METHODS

Cross-sectional associations of total blood mercury and depression were assessed in 6,911 adults age ≥20 in the National Health and Nutrition Examination Survey (NHANES), 2005-2008. The Patient Health Questionnaire-9 was used to assess depression (high likelihood of a depressive spectrum disorder diagnosis; score 5-27).

RESULTS

Unadjusted survey weighted logistic regression suggested that higher total blood mercury was associated with lower odds of depression (Odds Ratio  = 0.49, 95% Confidence Interval: 0.36-0.65, comparing the highest and lowest mercury quintiles). This association largely disappeared after adjustment for sociodemographic variables (income-poverty ratio, education, marital status). However, in age-stratified analyses, this inverse relationship remained in older adults (age ≥40) even after adjustment for sociodemographic variables. Simulation analyses adjusting for expected confounding effects of fish intake suggested that the inverse relationship among older adults may be plausibly attributed to residual confounding (Odds Ratio  = 0.75, 95% Confidence Interval: 0.50-1.12, comparing the highest and lowest mercury quintiles).

CONCLUSIONS

Higher total blood mercury was not associated with increased odds of depression. The lower odds of depression in older adults with higher total blood mercury may be due to residual confounding.

Effectiveness of collaborative care for depression in Italy. A randomized controlled trial

TRIAL DESIGN

This was a multicenter cluster-randomized controlled trial.

PARTICIPANTS

A total of 227 patients ≥18 years old with a new onset of depressive symptoms who screened positive on the first two items of the Patient Health Questionnaire-9 (PHQ-9) were recruited by primary care physicians (PCPs) of eight health districts of three Italian regions from September 2009 to June 2011.

INTERVENTION

PCPs of the intervention group received a specific collaborative care program including 2 days of intensive training, implementation of a stepped care protocol, depression management toolkit and scheduled meetings with a dedicated consultant psychiatrist.

OBJECTIVE

The objective was to determine whether a collaborative care program for depression management in primary care leads to higher remission rate than usual PCP care.

OUTCOMES

Outcome was clinical remission as expressed on PHQ-9 <5 at 3 months.

RANDOMIZATION

An independent researcher used computer-generated randomization to assign involved primary care groups to the two alternative arms.

BLINDING

PCPs and research personnel were not blinded.

RESULTS

The 223 PCPs enrolled recruited 227 patients (128 in collaborative care arm, 99 in the usual care arm). At 3 months (n=210), the proportion of patients who achieved remission was higher, though the difference was not statistically significant, in the collaborative care group. The effect size was of 0.11. When considering only patients with minor/major depression, collaborative care appeared to be more effective than usual care (P=.015).

CONCLUSIONS

The present intervention for managing depression in primary care, designed to be applicable to the Italian context, appears to be effective and feasible.

Rethinking the dose-response relationship between usage and outcome in an online intervention for depression: randomized controlled trial

Background

There is now substantial evidence that Web-based interventions can be effective at changing behavior and successfully treating psychological disorders. However, interest in the impact of usage on intervention outcomes has only been developed recently. To date, persistence with or completion of the intervention has been the most commonly reported metric of use, but this does not adequately describe user behavior online. Analysis of alternative measures of usage and their relationship to outcome may help to understand how much of the intervention users may need to obtain a clinically significant benefit from the program.

Objective

The objective of this study was to determine which usage metrics, if any, are associated with outcome in an online depression treatment trial.

Methods

Cardiovascular Risk E-couch Depression Outcome (CREDO) is a randomized controlled trial evaluating an unguided Web-based program (E-couch) based on cognitive behavioral therapy and interpersonal therapy for people with depression and cardiovascular disease. In all, 280 participants in the active arm of the trial commenced the program, delivered in 12 modules containing pages of text and activities. Usage data (eg, number of log-ins, modules completed, time spent online, and activities completed) were captured automatically by the program interface. We estimated the association of these and composite metrics with the outcome of a clinically significant improvement in depression score on the Patient Health Questionnaire (PHQ-9) of ≥5 points.

Results

In all, 214/280 (76.4%) participants provided outcome data at the end of the 12-week period and were included in the analysis. Of these, 94 (43.9%) participants obtained clinically significant improvement. Participants logged into the program an average of 18.7 times (SD 8.3) with most (62.1%, 133/214) completing all 12 modules. Average time spent online per log-in was 17.3 minutes (SD 10.5). Participants completed an average of 9 of 18 activities available within the program. In a multivariate regression model, only the number of activities completed per log-in was associated with a clinically significant outcome (OR 2.82, 95% CI 1.05-7.59). The final model predicted 7.4% of variance in outcome. Curve estimates indicated that significant logarithmic (P=.009) and linear (P=.002) relationships existed between activities completed per log-in and clinically significant change.

Conclusions

Only one objective measure of usage was independently associated with better outcome of a Web-based intervention of known effectiveness. The 4 usage metrics retained in the final step of the regression accounted for little outcome variance. Medium level users appeared to have little additional benefit compared to low users indicating that assumptions of a linear relationship between use and outcome may be too simplistic and further models and variables need to be explored to adequately understand the relationship.

Trauma history and depression predict incomplete adherence to antiretroviral therapies in a low income country

Background

As antiretroviral therapy (ART) for HIV becomes increasingly available in low and middle income countries (LMICs), understanding reasons for lack of adherence is critical to stemming the tide of infections and improving health. Understanding the effect of psychosocial experiences and mental health symptomatology on ART adherence can help maximize the benefit of expanded ART programs by indicating types of services, which could be offered in combination with HIV care.

Methodology

The Coping with HIV/AIDS in Tanzania (CHAT) study is a longitudinal cohort study in the Kilimanjaro Region that included randomly selected HIV-infected (HIV+) participants from two local hospital-based HIV clinics and four free-standing voluntary HIV counselling and testing sites. Baseline data were collected in 2008 and 2009; this paper used data from 36 month follow-up interviews (N = 468). Regression analyses were used to predict factors associated with incomplete self-reported adherence to ART.

Results

Incomplete ART adherence was significantly more likely to be reported amongst participants who experienced a greater number of childhood traumatic events: sexual abuse prior to puberty and the death in childhood of an immediate family member not from suicide or homicide were significantly more likely in the non-adherent group and other negative childhood events trended toward being more likely. Those with incomplete adherence had higher depressive symptom severity and post-traumatic stress disorder (PTSD). In multivariable analyses, childhood trauma, depression, and financial sacrifice remained associated with incomplete adherence.

Discussion

This is the first study to examine the effect of childhood trauma, depression and PTSD on HIV medication adherence in a low income country facing a significant burden of HIV. Allocating spending on HIV/AIDS toward integrating mental health services with HIV care is essential to the creation of systems that enhance medication adherence and maximize the potential of expanded antiretroviral access to improve health and reduce new infections.

Predictive validity and clinical utility of DSM-5 Somatic Symptom Disorder: prospective 1-year follow-up study

OBJECTIVE

To compare the predictive validity and clinical utility of DSM-IV somatoform disorders and DSM-5 Somatic Symptom Disorder (SSD) at 12-month follow-up.

METHODS

In a sample of psychosomatic inpatients (n=322, mean age=45.6 years (SD 10.0), 60.6% females) we prospectively investigated DSM-IV somatoform disorders and the DSM-5 diagnosis of SSD plus a variety of psychological characteristics, somatic symptom severity, and health-related quality of life at admission, discharge, and follow-up.

RESULTS

DSM-IV diagnoses and DSM-5 SSD similarly predicted physical functioning at follow-up; SSD also predicted mental functioning at follow-up. Bodily weakness, intolerance of bodily complaints, health habits, and somatic attribution at admission were significant predictors of physical functioning at follow-up. The change in physical functioning during inpatient therapy was a significant predictor for the course of physical functioning until follow-up.

CONCLUSIONS

Psychological symptoms appear to be predictively valid diagnostic criteria for the 12-month functional outcome in patients with SSD. Mental functioning can be better predicted by the DSM-5 diagnosis than by DSM-IV diagnoses. Not the change in single psychological features but in physical functioning during the treatment interval predicted the change in physical functioning until follow-up.

The EVIDENT-trial: protocol and rationale of a multicenter randomized controlled trial testing the effectiveness of an online-based psychological intervention

BACKGROUND

Depressive disorders are among the leading causes of worldwide disability with mild to moderate forms of depression being particularly common. Low-intensity treatments such as online psychological treatments may be an effective way to treat mild to moderate depressive symptoms and prevent the emergence or relapse of major depression.

METHODS/DESIGN

This study is a currently recruiting multicentre parallel-groups pragmatic randomized-controlled single-blind trial. A total of 1000 participants with mild to moderate symptoms of depression from various settings including in- and outpatient services will be randomized to an online psychological treatment or care as usual (CAU). We hypothesize that the intervention will be superior to CAU in reducing depressive symptoms assessed with the Personal Health Questionnaire (PHQ-9, primary outcome measure) following the intervention (12 wks) and at follow-up (24 and 48 wks). Further outcome parameters include quality of life, use of health care resources and attitude towards online psychological treatments.

DISCUSSION

The study will yield meaningful answers to the question of whether online psychological treatment can contribute to the effective and efficient prevention and treatment of mild to moderate depression on a population level with a low barrier to entry.
