Implementation of guideline-based care for depression in primary care

Racial Differences in Change in Physical Functioning in Older Male Veterans with HIV

Little is known about longitudinal change in physical functioning of older African American/Black and White HIV-infected persons. We examined up to 10 years of data on African American (N = 1,157) and White (N = 400) men with HIV infection and comparable HIV-negative men (n = 1,137 and 530, respectively), age 50-91 years from the Veterans Aging Cohort Study Survey sample. Physical functioning was assessed using the SF-12 (12-Item Short Form Health Survey) physical component summary (PCS) score. Mixed-effects models examined association of demographics, health conditions, health behaviors, and selected interactions with PCS score; HIV biomarkers were evaluated for HIV-infected persons. PCS scores were approximately one standard deviation below that of the general U.S. population of similar age. Across the four HIV/race groups, over time and through ages 65-75 years, PCS scores were maintained; differences were not clinically significant. PCS score was not associated with race or with interactions among age, race, and HIV status. CD4 and viral load counts of African American and White HIV-infected men were similar. Older age, low socioeconomic status, chronic health conditions and depression, lower body mass index, and smoking were associated with poorer PCS score in both groups. Exercising and, counterintuitively, being HIV infected were associated with better PCS score. Among these older African American and White male veterans, neither race nor HIV status was associated with PCS score, which remained relatively stable over time. Chronic disease, depression, and lack of exercise were associated with lower PCS score. To maintain independence in this population, attention should be paid to controlling chronic conditions, and emphasizing good health behaviors.

Depressive symptoms in late life in urban and semi-urban areas of South-West Greece: An undetected disorder?

OBJECTIVE

The objective of this study was to estimate the prevalence and probable under-diagnosis of depressive symptoms in elderly of an urban and semi-urban area in Greece.

MATERIALS AND METHODS

A cross-sectional study was conducted among the members of 4 days care centers for older people (KAPI), three in the municipality of Patras, West-Greece, and in one in Tripolis, Peloponnese, Greece. A total of 378 individuals took part in the study, aged >60 years. A questionnaire was developed to collect basic demographic data, including three questions from the European Health Interview Survey, regarding self-reported or by a physician-diagnosed depression. Moreover, to all participants the Greek validated version of the Geriatric Depression Scale-15 (GDS-15) was applied, to screen for depressive symptoms.

RESULTS

According to GDS-15, 48.1% of the studied population screened positive for depressive symptoms (38.6% moderate, 9.5% severe), whereas having ever been affected with chronic depression reported 19.0% by themselves. In 162 members of KAPI of Patras and in 106 of Tripolis, who never reported have been affected by depression and depressive symptoms were observed in 27.7% and 44.7%, respectively. In 28 individuals from Patras, who reported not to know if they have depression and in 10 from Tripolis, depressive symptoms were observed in 60.7% and 90%, respectively, applying the GDS-15.

CONCLUSION

Except the high prevalence, the present study reveals a remarkable under-detection of depressive symptoms in older adults. Various interventions in primary care are necessary so as to increase detection rates of depression among the elderly.

Screening for depression in the primary care population

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

The clinical effectiveness of stepped care systems for depression in working age adults: a systematic review

BACKGROUND

Stepped care service delivery models involve treatments that become increasingly intense through successive steps, with patients re-assigned via pre-defined decision criteria. This article reviews the clinical effectiveness of stepped care systems for depression in working age adults.

METHODS

Systematic literature review of quantitative clinical outcome evidence comprising 14 controlled and uncontrolled studies meeting specified criteria. Principal outcomes were (a) recovery rates, defined as patients no longer meeting clinical cut-off criteria for the specific outcome measure and (b) treatment response rates, defined as a 50% decrease in outcome measure score.

RESULTS

Stepped care systems had recovery rates ranging predominantly between 40% and 60% and response rates approximating 60%. Studies comparing stepped care with usual/enhanced usual care tended to find significant differences favouring stepped care. The median recovery odds ratio was 1.31 (interquartile intervals of 1.05 and 1.66; k=7 studies). The median comparative Cohen's d effect size estimate was 0.41 (interquartile intervals 0.25 and 0.45; k=5 studies).

LIMITATIONS

The inclusion of uncontrolled studies could be seen as reducing the overall quality of evidence and a meta-analysis was not included due to limitations with the available data.

CONCLUSIONS

Evidence suggested that stepped care interventions for depression are at least as effective as usual care. However, the clinical and organisational superiority of stepped care is yet to be scientifically verified. Differential benefits of stepped care may ultimately depend on service quality. Further research investigating and comparing the specific components and configurations of stepped care interventions are indicated.

Implementing evidence-based guidelines for managing depression in elderly patients: a Norwegian perspective

Depression in the elderly is common and exhibits a distinctive phenomenology, due to neurobiological, physiological, psychological and social changes related to ageing. Most elderly with depression are managed in primary health care. Although the number of scientific publications related to geriatric psychiatry has increased, there are still important gaps. Implementation of evidence-based guidelines for managing depression in primary care has had limited success, but has led to improvements compared to standard care. It is logical that the determinants (barriers and enablers) of implementing depression guidelines can be identified and can guide the selection of more effective implementation strategies that are tailored to address those determinants. We are testing that logic as part of a multinational implementation research project called 'Tailored Implementation for Chronic Diseases' (TICD). Our focus in Norway is on the management of depression in the elderly in primary care. We will identify the determinants of implementing evidence-based recommendations using various methods and comparing those methods. We will then use different methods to match the implementation interventions to the identified determinants and compare those methods. Finally, we will evaluate the resulting tailored implementation strategy in a randomized trial.

Stepped care treatment for depression and anxiety in primary care. a randomized controlled trial

BACKGROUND

Depressive and anxiety disorders are common in general practice but not always treated adequately. Introducing stepped care might improve this. In this randomized trial we examined the effectiveness of such a stepped care model.

METHODS

The study population consisted of primary care attendees aged 18-65 years with minor or major DSM-IV depressive and/or anxiety disorders, recruited through screening. We randomized 120 patients to either stepped care or care as usual. The stepped care program consisted of (1) watchful waiting, (2) guided self-help, (3) short face-to-face problem solving treatment and (4) pharmacotherapy and/or specialized mental health care. Patients were assessed at baseline and after 8, 16 and 24 weeks.

RESULTS

Symptoms of depression and anxiety decreased significantly over time for both groups. However, there was no statistically significant difference between the two groups (IDS: P = 0.35 and HADS: P = 0.64). The largest, but not significant, effect (d = -0.21) was found for anxiety on T3. In both groups approximately 48% of the patients were recovered from their DSM-IV diagnosis at the final 6 months assessment.

CONCLUSIONS

In summary we could not demonstrate that stepped care for depression and anxiety in general practice was more effective than care as usual. Possible reasons are discussed.

Steps for implementing collaborative care programs for depression

Numerous studies have demonstrated that collaborative care (care management) for depression improves outcomes, yet few clinics have implemented this evidence-based practice. To promote adoption of this best practice, our objective was to describe the steps needed to tailor collaborative care models for local needs, resources, and priorities while maintaining fidelity to the evidence base. Based on lessons learned from 2 multisite Veterans Affairs implementation studies conducted in 2 different clinical, organizational, and geographic contexts, we describe in detail the steps needed to adapt an evidence-based collaborative care program for depression for local context while maintaining highly fidelity to the research evidence. These steps represent a detailed checklist of decisions and action items that can be used as a tool to plan the implementation of a collaborative care model for depression. We also identify other tools (eg, decision support systems, suicide risk assessment) and resources (eg, training materials) that will support implementation efforts. These implementation tools should help clinicians and administrators develop informed strategies for rolling out collaborative care models for depression.

Time to depression treatment in primary care among HIV-infected and uninfected veterans

BACKGROUND

Multiple factors, including patient characteristics, competing demands, and clinic type, impact delivery of depression treatment in primary care.

OBJECTIVE

Assess whether depression severity and HIV serostatus have a differential effect on time to depression treatment among depressed patients receiving primary care at Infectious Disease or General Medicine clinics.

DESIGN

Multicenter prospective cohort, (Veterans Aging Cohort Study), comparing HIV-infected to uninfected patients.

PARTICIPANTS AND MEASURES

The total cohort consisted of 3,239 HIV-infected and 3,227 uninfected patients. Study inclusion criteria were untreated depressive symptoms, based on a Patient Health Questionnaire (PHQ-9) score of greater than 9, and no antidepressants or mental health visits in the 90 days prior to PHQ-9 assessment. Treatment was defined as antidepressant receipt or mental health visit within 90 days following PHQ-9 assessment. Depression severity based on PHQ-9 scores was defined as mild-moderate (greater than 9 to 19) and severe (20 or greater). Kaplan-Meier curves were used to estimate time to treatment by depression severity and HIV serostatus. Cox proportional hazards methods adjusted for covariates were used.

KEY RESULTS

Overall, 718 (11%) of the cohort met inclusion criteria, 258 (36%) of whom received treatment. Median time to treatment was 7 days [95% confidence interval (CI) = 4, 13] and was shortest for severely depressed HIV-infected patients (0.5 days; 95% CI = 0.5, 6, p = 0.04). Compared to mildly-moderately depressed uninfected patients, severely depressed HIV-infected patients were significantly more likely to receive treatment [adjusted hazard ratio (HR) 1.67, 95% CI = 1.07, 2.60), whereas mildly-moderately depressed HIV-infected patients (adjusted HR 1.10, 95% CI = 0.79, 1.52) and severely depressed uninfected patients (adjusted HR 0.93, 95% CI = 0.60, 1.44) were not.

CONCLUSIONS

In this large cohort, time to primary care treatment of depression was shortest among severely depressed HIV-infected patients. Regardless of HIV serostatus, if depression was not treated on the assessment day, then it was unlikely to be treated within a 90-day period, leading to the majority of depression being untreated.

What work has to be done to implement collaborative care for depression? Process evaluation of a trial utilizing the Normalization Process Model

Background

There is a considerable evidence base for 'collaborative care' as a method to improve quality of care for depression, but an acknowledged gap between efficacy and implementation. This study utilises the Normalisation Process Model (NPM) to inform the process of implementation of collaborative care in both a future full-scale trial, and the wider health economy.

Methods

Application of the NPM to qualitative data collected in both focus groups and one-to-one interviews before and after an exploratory randomised controlled trial of a collaborative model of care for depression.

Results

Findings are presented as they relate to the four factors of the NPM (interactional workability, relational integration, skill-set workability, and contextual integration) and a number of necessary tasks are identified. Using the model, it was possible to observe that predictions about necessary work to implement collaborative care that could be made from analysis of the pre-trial data relating to the four different factors of the NPM were indeed borne out in the post-trial data. However, additional insights were gained from the post-trial interview participants who, unlike those interviewed before the trial, had direct experience of a novel intervention. The professional freedom enjoyed by more senior mental health workers may work both for and against normalisation of collaborative care as those who wish to adopt new ways of working have the freedom to change their practice but are not obliged to do so.

Conclusions

The NPM provides a useful structure for both guiding and analysing the process by which an intervention is optimized for testing in a larger scale trial or for subsequent full-scale implementation.

Stepped care for depression and anxiety: from primary care to specialized mental health care: a randomised controlled trial testing the effectiveness of a stepped care program among primary care patients with mood or anxiety disorders

BACKGROUND

Mood and anxiety disorders are highly prevalent and have a large impact on the lives of the affected individuals. Therefore, optimal treatment of these disorders is highly important. In this study we will examine the effectiveness of a stepped care program for primary care patients with mood and anxiety disorders. A stepped care program is characterized by different treatment steps that are arranged in order of increasing intensity.

METHODS

This study is a randomised controlled trial with two conditions: stepped care and care as usual, whereby the latter forms the control group. The stepped care program consists of four evidence based interventions: (1) Watchful waiting, (2) Guided self-help, (3) Problem Solving Treatment and (4) Medication and/or specialized mental health care. The study population consists of primary care attendees aged 18-65 years. Screeners are sent to all patients of the participating general practitioners. Individuals with a Diagnostic and Statistical Manual of mental disorders (DSM) diagnosis of major depression, dysthymia, panic disorder (with or without agoraphobia), generalized anxiety disorder, or social phobia are included as well as individuals with minor depression and anxiety disorders. Primary focus is the reduction of depressive and anxiety symptoms. Both conditions are monitored at 8, 16 and 24 weeks.

DISCUSSION

This study evaluates the effectiveness of a stepped care program for patients with depressive and anxiety disorder. If effective, a stepped care program can form a worthwhile alternative for care as usual. Strengths and limitations of this study are discussed.

Clinic-level process of care for depression in primary care settings

Multi-component models for improving depression care target primary care (PC) clinics, yet few studies document usual clinic-level care. This case comparison assessed usual processes for depression management at 10 PC clinics. Although general similarities existed across sites, clinics varied on specific processes, barriers, and adherence to practice guidelines. Screening for depression conformed to guidelines. Processes for assessment, diagnosis, treatment, and follow-up varied to different degrees in different clinics. This individuality of usual care should be defined prior to quality improvement interventions, and may provide insights for introducing or tailoring changes, as well as improving interpretation of evaluation results.

Balancing rigour and relevance in guideline development for depression: the case for comprehensive cohort studies

PURPOSE

Clinical guidelines for the treatment of depression have not yet realized their potential for improving the delivery of the psychological therapies within national healthcare systems. Current guidelines emphasize treatment efficacy and issues in service delivery are relatively neglected. Hence, there is a hierarchy of evidence in which randomized efficacy trials are given primacy over naturalistic (i.e. practice-based) data. Such a strategy is inadequate to address important questions about best delivery of safe and acceptable psychological therapies and exacerbates divisions between research and practice communities.

METHODS

Selected narrative review.

RESULTS

Both randomized controlled trials and practice-based studies have shortcomings that can be ameliorated by the adoption of practical clinical trials embedded within large cohort studies - that is, comprehensive cohort studies.

CONCLUSIONS

Comprehensive cohort studies have the potential to deliver an evidence base which is both rigorous and relevant. This could satisfy the scientific community as well as allowing practitioners and service users to be fully involved and committed to the process of collecting evidence and implementing guidance. We argue this would be a sound foundation upon which to build an evidence base upon which to develop future clinical guidelines for depression.

A survey of primary care provider attitudes and behaviors regarding treatment of adult depression: what changes after a collaborative care intervention?

OBJECTIVE

To assess primary care provider (PCP) attitudes and self-reported behavior with regard to identifying and managing depression in adult patients before and after a chronic disease/collaborative care intervention.

METHOD

A self-administered cross-sectional survey was conducted in 6 targeted practices among 39 family practice physicians, family nurse practitioners, and residents before and after implementation of a depression in primary care project. In this project, the sites received tools and training in depression screening and guideline-concordant treatment, facilitated referral services for patients to access mental health providers, psychiatric phone consultation, patient education materials, and services of a depression care manager. The project was conducted from June 2003 through June 2006.

RESULTS

Comparison of responses prior to and after the intervention showed that significantly or nearly significantly larger proportions of PCPs endorsed the importance of depression as a patient presenting problem (p = .000), increased provision of supportive counseling (p = .13), more often identified counseling or therapy as effective (p = .07), and more often referred patients to mental health services (p = .001). PCPs also reduced their perception that treating depression is time consuming (p = .000).

CONCLUSIONS

After a chronic disease/collaborative care approach to depression treatment in primary care was implemented, PCP attitudes and behaviors about depression treatment were significantly modified. More guideline-concordant care, and increased collaboration with mental health services, was reported. Implications for future primary care depression intervention activities and research are discussed.

Prevalence of depression-PTSD comorbidity: implications for clinical practice guidelines and primary care-based interventions

BACKGROUND

Compared to those with depression alone, depressed patients with posttraumatic stress disorder (PTSD) experience more severe psychiatric symptomatology and factors that complicate treatment.

OBJECTIVE

To estimate PTSD prevalence among depressed military veteran primary care patients and compare demographic/illness characteristics of PTSD screen-positive depressed patients (MDD-PTSD+) to those with depression alone (MDD).

DESIGN

Cross-sectional comparison of MDD patients versus MDD-PTSD+ patients.

PARTICIPANTS

Six hundred seventy-seven randomly sampled depressed patients with at least 1 primary care visit in the previous 12 months. Participants composed the baseline sample of a group randomized trial of collaborative care for depression in 10 VA primary care practices in 5 states.

MEASUREMENTS

The Patient Health Questionnaire-9 assessed MDD. Probable PTSD was defined as a Primary Care PTSD Screen > or = 3. Regression-based techniques compared MDD and MDD-PTSD+ patients on demographic/illness characteristics.

RESULTS

Thirty-six percent of depressed patients screened positive for PTSD. Adjusting for sociodemographic differences and physical illness comorbidity, MDD-PTSD+ patients reported more severe depression (P < .001), lower social support (P < .001), more frequent outpatient health care visits (P < .001), and were more likely to report suicidal ideation (P < .001) than MDD patients. No differences were observed in alcohol consumption, self-reported general health, and physical illness comorbidity.

CONCLUSIONS

PTSD is more common among depressed primary care patients than previously thought. Comorbid PTSD among depressed patients is associated with increased illness burden, poorer prognosis, and delayed response to depression treatment. Providers should consider recommending psychotherapeutic interventions for depressed patients with PTSD.

Current practices in depression care

Despite improved awareness among the medical community concerning common mental health disorders, the high prevalence of depression in the United States remains unchanged and has been compounded by increasing evidence of gaps in mental health care for ethnic and racial minorities. Thus, there is a strong need for the timely creation of comprehensive educational initiatives aimed at improving the quality of care provided by mental health professionals and primary care physicians. Fundamental to this process is the examination of current treatment standards, as well as identification of practices that require improved physician education. Consistent use of appropriate screening tools, diagnostic accuracy and timeliness, continual assessment of illness severity, adherence to practice guidelines, and individualized patient care need heightened attention to improve outcomes. This article describes the most prevalent types of depression and summarizes current practices in depression care, with an emphasis on treatment standards and opportunities for improved performance.
