Older patients' aversion to antidepressants. A qualitative study

Effectiveness of the Program to Encourage Active, Rewarding Lives (PEARLS) to reduce depression: a multi-state evaluation

Introduction

An estimated 15% of community-dwelling older adults have depressive symptoms in the U.S. The Program to Encourage Active, Rewarding Lives (PEARLS) is an evidence-based program for managing late-life depression. PEARLS is a home/community-based collaborative care model delivered by community-based organizations to improve access to quality depression care. Trained staff actively screen for depression to improve recognition, teach problem-solving and activity planning skills for self-management, and connect participants to other supports and services as needed.

Methods

This study examined 2015-2021 data from 1,155 PEARLS participants across four states to assess PEARLS effectiveness to reduce depressive symptoms. The clinical outcomes were measured by the self-reported PHQ-9 instrument to assess changes in depressive symptoms scored as depression-related severity, clinical remission, and clinical response. A generalized estimating equation (GEE) model was fitted to examine changes in composite PHQ-9 scores from baseline to the final session. The model adjusted for participants' age, gender, race/ethnicity, education level, income level, marital status, number of chronic conditions, and number of PEARLS sessions attended. Cox proportional hazards regression models were conducted to estimate the hazard ratio for improvement of depressive symptoms (i.e., remission or response), while adjusting for the covariates.

Results

PHQ-9 scale scores significantly improved from baseline to their final sessions (mean difference = -5.67, SEM = 0.16, p < 0.001). About 35% of participants achieved remission with PHQ-9 score < 5. Compared to participants with mild depression, patients with moderate depression (HR = 0.43, 95%CI = 0.35-0.55), moderately severe depression (HR = 0.28, 95%CI = 0.21-0.38), and severe depression (HR = 0.22 95%CI = 0.14-0.34) were less likely to experience clinical remission with PHQ-9 score < 5, while adjusting for the covariates. About 73% achieved remission based on no longer having one or both cardinal symptoms. Compared to participants with mild depression, patients with moderate depression (HR = 0.66, 95%CI = 0.56-0.78), moderately severe depression (HR = 0.46, 95%CI = 0.38-0.56), and severe depression (HR = 0.38, 95%CI = 0.29-0.51) were less likely to experience clinical remission, while adjusting for the covariates. Nearly 49% of participants had a clinical response or a ≥ 50% decrease in PHQ-9 scores over time. There were no differences between the severity of depression groups based on the time to clinical response.

Discussion

Findings confirm that PEARLS is an effective program to improve depressive symptoms among older adults in diverse real-world community settings and can be a more accessible option for depressive older adults who are traditionally underserved by clinical care.

The Relationship Between Successful Aging and All-Cause Mortality Risk in Older Adults: A Systematic Review and Meta-Analysis of Cohort Studies

Background

This meta-analysis aimed to explore the effect of successful aging (SA) on all-cause mortality risk in older people to provide a theoretical basis for promoting SA.

Methods

PubMed, Embase, CINAHL, CNKI, and WanFang databases (inception to March 4, 2021) were searched for cohort studies to evaluate the relationship between SA and mortality in older people. A random-effects model was used to synthesis hazard ratio and 95% confidence intervals. Quality assessment was performed using the Newcastle–Ottawa scale. All statistical analyses were conducted in STATA 16.0.

Results

In total, 21,158 older adults from 10 studies were included in the current systematic review and meta-analysis. The SA group tended to have 50% lower risk of all-cause mortality than the non-SA group (pooled hazard ratio = 0.50, 95% confidence intervals: 0.35–0.65, P < 0.001; I² = 58.3%). The risk of all-cause mortality in older people increased by 17% for each unit increment in the healthy aging index (HAI) (I² = 0%, P = 0.964). Compared with the reference group (HAI 0-2), older people with HAI 3-4, HAI 5-6, and HAI 7-10 had 1.31-fold, 1.73-fold, and 2.58-fold greater risk of all-cause mortality, respectively. Subgroup analysis did not reveal possible sources of heterogeneity.

Conclusions

This meta-analysis suggests that older adults with SA reduced the risk of all-cause mortality by 50%. However, few interventional studies have been conducted. Therefore, healthcare providers must be aware of the relationship between SA and mortality risk and actively develop intervention methods for helping old people achieve SA.

Health Control Beliefs and Attitude Toward Treatment in Psychiatric and Non-Psychiatric Clinical Samples

Although there is accumulating evidence on the potential influencing factors of medication adherence, the knowledge about patients' attitudes and beliefs toward treatment is only partly utilized in adherence-improving strategies. Several internal and external factors determining adherence have been described regarding many chronic somatic diseases but in recent research, insight on psychiatric patients has been exclusively lacking. As a result, there is a scarcity of effective adherence-improving interventions. Identification of any specific differences or similarities between the attitudes toward treatment of psychiatric and non-psychiatric patients would help to support adherent behavior. We recruited 189 participants from four departments of general psychiatry (GEN PSYCH, n = 106), addictology (ADDICT, n = 42) and somatic diseases (NON PSYCH, n = 41). The Patient's Health Belief Questionnaire on Psychiatric Treatment (PHBQPT) was performed to assess the patients' attitude toward drug treatment, perceived health locus of control, and psychological reactance. The most robust difference of the PHBQT scores occurred between the GEN PSYCH and ADDICT subgroups. ADDICT patients scored significantly higher on the internal and external health locus of control and on the Psychological Reactance subscale as well. While GEN PSYCH subjects provided higher scores on the Positive Aspect of Medication compared to ADDICT persons. Interestingly, the only difference between the GEN PSYCH and NON-PSYCH groups was the more pronounced mistrust in physicians in the case of psychiatric patients. Our data suggest that mistrust toward medication does not differ in psychiatric and non-psychiatric samples, while the acceptance of the doctor's competency may be stronger in the non-psychiatric sample. The analysis of these factors provides information which could help us better understand this important issue and to develop more efficient interventions for improving adherence.

'I wanted to talk about it, but I couldn't', an H70 focus group study about experiencing depression in early late life

BACKGROUND

Knowledge about experiences of depression among younger-old adults from the general population is limited. The aim was to explore experiences of depression in early late life.

METHODS

Sixteen participants in the population-based Gothenburg H70 Birth Cohort Studies (12 women and 4 men) who had reported a history of depression between ages 60-70 took part in focus group discussions (n = 4). Data were analyzed using focus group methodology.

RESULTS

The analysis resulted in the overall theme 'I wanted to talk about it, but I couldn't'. The participants expressed unmet needs of communication about depression with family, friends, and healthcare staff. Participants wanted to know more about the causes and effects of depression, available treatment options and how to avoid recurrence. Lack of knowledge was a source of frustration; trust in health care providers was diminished. Being retired meant that opportunities for communication with co-workers were no longer available, and this made it harder to break negative thought and behavioral patterns. Being depressed meant losing one's normal self, and participants were grieving this. Thoughts of death and suicide were experienced in solitude; knowing that there was an escape could generate a feeling of comfort and control.

CONCLUSIONS

Younger-old adults have expressed a need to talk about their experiences of depression. They would like to know more about available treatments, potential side effects, and how to avoid recurrence. Care providers also need to be aware there is a need for an existential dialogue about death.

Use of the Patient Health Questionnaire (PHQ-9) in Practice: Interactions between patients and physicians

We analyze the use of nine-item Patient Health Questionnaire (PHQ-9), an instrument that is widely used in diagnosing and determining the severity of depression. Using conversation analysis, we show how the doctor deploys the PHQ-9 in response to the patient's doubts about whether she is depressed. Rather than relaying the PHQ-9 verbatim, the doctor deviates from the wording so that the response options are selectively offered to upgrade the severity of the patient's symptoms. This works in favor of a positive diagnosis and is used to justify a treatment recommendation that the patient previously resisted. This contrasted with the rest of the data set, where diagnosis was either not delivered (as patients are presenting with ongoing problems) or delivered without using the PHQ-9. When clinician-administered, the PHQ-9 can be influenced by how response items are presented. This can lead to either downgrading or upgrading the severity of depression.

Combining mirtazapine with SSRIs or SNRIs for treatment-resistant depression: the MIR RCT

BACKGROUND

Depression is usually managed in primary care and antidepressants are often the first-line treatment, but only half of those treated respond to a single antidepressant.

OBJECTIVES

To investigate whether or not combining mirtazapine with serotonin-noradrenaline reuptake inhibitor (SNRI) or selective serotonin reuptake inhibitor (SSRI) antidepressants results in better patient outcomes and more efficient NHS care than SNRI or SSRI therapy alone in treatment-resistant depression (TRD).

DESIGN

The MIR trial was a two-parallel-group, multicentre, pragmatic, placebo-controlled randomised trial with allocation at the level of the individual.

SETTING

Participants were recruited from primary care in Bristol, Exeter, Hull/York and Manchester/Keele.

PARTICIPANTS

Eligible participants were aged ≥ 18 years; were taking a SSRI or a SNRI antidepressant for at least 6 weeks at an adequate dose; scored ≥ 14 points on the Beck Depression Inventory-II (BDI-II); were adherent to medication; and met the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, criteria for depression.

INTERVENTIONS

Participants were randomised using a computer-generated code to either oral mirtazapine or a matched placebo, starting at a dose of 15 mg daily for 2 weeks and increasing to 30 mg daily for up to 12 months, in addition to their usual antidepressant. Participants, their general practitioners (GPs) and the research team were blind to the allocation.

MAIN OUTCOME MEASURES

The primary outcome was depression symptoms at 12 weeks post randomisation compared with baseline, measured as a continuous variable using the BDI-II. Secondary outcomes (at 12, 24 and 52 weeks) included response, remission of depression, change in anxiety symptoms, adverse events (AEs), quality of life, adherence to medication, health and social care use and cost-effectiveness. Outcomes were analysed on an intention-to-treat basis. A qualitative study explored patients' views and experiences of managing depression and GPs' views on prescribing a second antidepressant.

RESULTS

There were 480 patients randomised to the trial (mirtazapine and usual care, n = 241; placebo and usual care, n = 239), of whom 431 patients (89.8%) were followed up at 12 weeks. BDI-II scores at 12 weeks were lower in the mirtazapine group than the placebo group after adjustment for baseline BDI-II score and minimisation and stratification variables [difference -1.83 points, 95% confidence interval (CI) -3.92 to 0.27 points; p = 0.087]. This was smaller than the minimum clinically important difference and the CI included the null. The difference became smaller at subsequent time points (24 weeks: -0.85 points, 95% CI -3.12 to 1.43 points; 12 months: 0.17 points, 95% CI -2.13 to 2.46 points). More participants in the mirtazapine group withdrew from the trial medication, citing mild AEs (46 vs. 9 participants).

CONCLUSIONS

This study did not find convincing evidence of a clinically important benefit for mirtazapine in addition to a SSRI or a SNRI antidepressant over placebo in primary care patients with TRD. There was no evidence that the addition of mirtazapine was a cost-effective use of NHS resources. GPs and patients were concerned about adding an additional antidepressant.

LIMITATIONS

Voluntary unblinding for participants after the primary outcome at 12 weeks made interpretation of longer-term outcomes more difficult.

FUTURE WORK

Treatment-resistant depression remains an area of important, unmet need, with limited evidence of effective treatments. Promising interventions include augmentation with atypical antipsychotics and treatment using transcranial magnetic stimulation.

The value of an embedded qualitative study in a trial of a second antidepressant for people who had not responded to one antidepressant: understanding the perspectives of patients and general practitioners

BACKGROUND

Depression is the leading cause of disability worldwide, and is a major contributor to the overall global burden of disease. The number of prescriptions for antidepressants has risen dramatically in recent years yet up to 50% of patients who are treated for depression with antidepressants do not report feeling better as a result of treatment, and do not show the desired improvement on depression measures. We report a qualitative study embedded in a trial of second antidepressant for people who had not responded to one antidepressant, exploring the acceptability of a combination of antidepressants from the perspectives of both patients and practitioners, together with experiences of participating in a clinical trial.

METHODS

A qualitative study embedded in a randomized controlled trial investigating the effectiveness and cost-effectiveness of combining mirtazapine with Serotonin-Noradrenaline Reuptake Inhibitor (SNRI) or Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants versus SNRI or SSRI therapy alone (the MIR trial). 59 interviews were conducted with people who declined to participate in the trial, people who completed the study and people who withdrew from the intervention, and 16 general practitioners.

RESULTS

Across the data-sets, four main themes were identified: the hard work of managing depression, uncertainties over the value of a second antidepressant, help-seeking at a point of crisis, and attainment and maintenance of a hard-won equilibrium.

CONCLUSIONS

Exploring reasons for declining to participate in a trial of a second antidepressant in people who had not responded to one antidepressant suggests that people who are already taking one antidepressant may be reluctant to take a second, being wary of possible side-effects, but also being unconvinced of the logic behind such a combination. In addition, people describe being in a state of equilibrium and reluctant to make a change, reflecting that this equilibrium is 'hard-won' and they are unwilling to risk disturbing this. This makes some people reluctant to enrol in a clinical trial. Understanding a patient's view on medication is important for GPs when discussing antidepressants.

Talking about depression during interactions with GPs: a qualitative study exploring older people's accounts of their depression narratives

BACKGROUND

Older people can struggle with revealing their depression to GPs and verbalising preferences regarding its management. This contributes to problems for GPs in both detecting and managing depression in primary care. The aim of this study was to explore older people's accounts of how they talk about depression and possible symptoms to improve communication about depression when seeing GPs.

METHODS

Adopting a qualitative Interpretivist methodological approach, semi-structured interviews were conducted by IG based on the principles of grounded theory and situational analysis. GPs working in north east England recruited patients aged over 65 with depression. Data analysis was carried out with a process of constant comparison, and categories were developed via open and axial coding and situational maps. There were three levels of analysis; the first developed open codes which informed the second level of analysis where the typology was developed from axial codes. The typology derived from second level analysis only is presented here as older people's views are rarely reported in isolation.

RESULTS

From the sixteen interviews with older people, it was evident that there were differences in how they understood and accepted their depression and that this influenced what they shared or withheld in their narratives. A typology showing three categories of older people was identified: those who appeared to talk about their depression freely yet struggled to accept aspects of it (Superficial Accepter), those who consolidated their ideas about depression aloud (Striving to Understand) and those who shared minimal detail about their depression and viewed it as part of them rather than a treatable condition (Unable to Articulate). The central finding was that older people's acceptance and understanding of their depression guided their depression narratives.

CONCLUSIONS

This study identified differences between older people in ways they understand, accept and share their depression. Recognising that their depression narratives can change and listening for patterns in what older people share or withhold may help GPs in facilitating communication to better understand the patient when they need to implement alternative approaches to patient management.

Treatment Initiation for New Episodes of Depression in Primary Care Settings

BACKGROUND

Depression is prevalent and costly, but despite effective treatments, is often untreated. Recent efforts to improve depression care have focused on primary care settings. Disparities in treatment initiation for depression have been reported, with fewer minority and older individuals starting treatment.

OBJECTIVE

To describe patient characteristics associated with depression treatment initiation and treatment choice (antidepressant medications or psychotherapy) among patients newly diagnosed with depression in primary care settings.

DESIGN

A retrospective observational design was used to analyze electronic health record data.

PATIENTS

A total of 241,251 adults newly diagnosed with depression in primary care settings among five health care systems from 2010 to 2013.

MAIN MEASURES

ICD-9 codes for depression, following a 365-day period with no depression diagnosis or treatment, were used to identify new depression episodes. Treatment initiation was defined as a completed psychotherapy visit or a filled prescription for antidepressant medication within 90 days of diagnosis. Depression severity was measured with Patient Health Questionnaire (PHQ-9) scores on the day of diagnosis.

KEY RESULTS

Overall, 35.7% of patients with newly diagnosed depression initiated treatment. The odds of treatment initiation among Asians, non-Hispanic blacks, and Hispanics were at least 30% lower than among non-Hispanic whites, controlling for all other variables. The odds of patients aged  ≥ 60 years starting treatment were half those of patients age 44 years and under. Treatment initiation increased with depression severity, but was only 53% among patients with a PHQ-9 score of ≥ 10. Among minority patients, psychotherapy was initiated significantly more often than medication.

CONCLUSIONS

Screening for depression in primary care is a positive step towards improving detection, treatment, and outcomes for depression. However, study results indicate that treatment initiation remains suboptimal, and disparities persist. A better understanding of patient factors, and particularly system-level factors, that influence treatment initiation is needed to inform efforts by heath care systems to improve depression treatment engagement and to reduce disparities.

A randomized preference trial of cognitive-behavioral therapy and yoga for the treatment of worry in anxious older adults

Background

Worry is a common problem among older adults. Cognitive-behavioral therapy is the most studied nonpharmacological intervention and it has demonstrated efficacy in reducing late-life worry and anxiety. Although the evidence-base is smaller, yoga has been shown to reduce anxiety and stress. However, little is known about the relative effectiveness of these two nonpharmacological interventions. Further, the impact of patient preference on outcomes is unknown.

Purpose: The purpose to this study is to compare the effectiveness of cognitive-behavioral therapy (CBT) with yoga for improving late-life worry, anxiety, and sleep. We will also examine the effects of preference and selection on outcomes, adherence, and attrition.

Methods

We are conducting a two-stage randomized preference trial comparing CBT and yoga for the reduction of worry in a sample of anxious older adults. Five hundred participants will be randomized to either the preference trial (participants choose the intervention; N = 250) or to the randomized trial (participants are randomized to one of the two interventions; N = 250) with equal probability. CBT consists of 10 telephone-based sessions with an accompanying workbook. Yoga consists of 10 weeks of group yoga classes (twice a week) that is modified for use with older adults.

Conclusions

The study design is based on feedback from anxious older adults who wanted more nonpharmacological options for intervention as well as more input into the intervention they receive. It is the first head-to-head comparison of CBT and yoga for reducing late-life worry and anxiety. It will also provide information about how intervention preference affects outcomes.

A qualitative study on older primary care patients' perspectives on depression and its treatments - potential barriers to and opportunities for managing depression

Background

Depression is one of the most common mental disorders in old age and is associated with various negative health consequences for the affected individual. Studies suggest that patients’ views on depression have an impact on help-seeking behaviour and treatment. It is thus important to investigate the patient’s perspective in order to ascertain optimum management of depression in late life. However, studies on depression and its treatment exploring the perspectives of primary care patients 75 years or older, are rare.

Methods

Qualitative data was collected in semi-structured interviews with 12 primary care patients 75 years of age or older with symptoms of depression. Data was analysed using qualitative content analysis.

Results

The study’s results show the multifaceted views on and treatment of depression in primary care patients 75 years of age or older. Some patients seemed well informed about depression and believed in the efficacy of different treatments, such as medications or psychotherapy. However, some individuals had misconceptions about depression and its treatments. Patients mentioned that they would rather avoid talking about depression within their social network, in part of fear of negative reactions. Furthermore, participants believed that other people had little understanding for people with depression. Patients had different views on the relevance of the general practitioner’s (GP) role in treating depression; some patients believed that the GP had little importance in the treatment of depression.

Conclusions

This study identified positive views of primary care patients 75 years of age or older towards depression as well as views that might hinder optimal treatments. Exemplary implications for an improved management of depression are: educating older adults about depression via age-specific information and having professionals encourage patients in believing that depression is a recognised disorder.

Reducing Polypharmacy from the Perspectives of General Practitioners and Older Patients: A Synthesis of Qualitative Studies

BACKGROUND

Polypharmacy, common in elderly multimorbid adults, leads to increased iatrogenic health risks. Yet, no consistent approach to stopping medicines exists in primary healthcare.

OBJECTIVES

Our objective was to synthesize qualitative studies exploring the perspectives and experiences of general practitioners (GPs) and older patients in reducing polypharmacy and to discover approaches already being practiced.

METHODS

We conducted a search in the PubMed, Cochrane Library, Web of Science Core Collection, and Scopus databases to identify qualitative studies in the primary care setting addressing multimorbid older patients and polypharmacy reduction. The seven-step model of meta-ethnography allowed for cross-interpretation between studies considering their original context and developing theories.

RESULTS

A total of 14 studies from the perspectives of patients (n = 6) and providers (n = 8) were included, although discontinuing medicines only occurred as a sub-theme in patient studies. Emerging key concepts for patients were experimenting with medicines, attitudes and experiences towards medicines, necessity of prioritizing treatments, relationship to GP, and system-related contributors. For GPs, they covered assumptions about elderly patients, interface prescribing problems, evidence-based guidelines, failure to meet the challenge of complex decision-making, and solutions.

DISCUSSION

Complex medication regimens and uncertainties in decision making are challenges for both GPs and patients. For patients, symptom experiences with medicines, relationship with their prescriber, and fragmented care are at the forefront; for GPs, it is the decision-making responsibility in the context of unsuitable guidelines, time constraints, and deficient multidisciplinary co-operation. Heuristics such as prioritizing and individualizing treatments and relaxation of guidelines emerged. These strategies require professional awareness of the problem and establishing a trusting, patient-centered consultation style and supportive work conditions.

Conflict in Men's Experiences With Antidepressants

While men's experiences of depression and help seeking are known to be shaped by gender, there is little research which examines their experience of using antidepressants to treat this. This study is based on in-depth, narrative-style interviews with 20 New Zealand men who had used antidepressants. The analysis identified a number of areas of conflict in the men's accounts of using this medication. Conflict centered on the way taking antidepressants was seen as undermining personal control while also allowing users to take charge of their problems; facilitating general functioning while undermining sexual functioning; relieving emotional distress while undermining emotional vitality; and the tension participants felt between making autonomous judgments about the value of antidepressants and relying on the "expertise" of others. Participants negotiated these conflicts in a variety of ways. In some cases, antidepressants were positioned as being able to affirm aspects of traditional masculinity, while a smaller number of participants managed these conflicts by redefining aspects of their own masculinity in ways that contrasted with dominant constructions. This research is limited by the sample of older, more privileged men in the context of New Zealand culture which favors macho forms of masculinity. In similar contexts, mental health practitioners should be mindful of the conflicts that men might experience in relation to their antidepressant use. Facilitating men's exploration of these issues may enable them to make better decisions about treatment options or to provide more effective support to those who have opted for antidepressant treatment.

Evaluating antidepressant treatment prior to adding second-line therapies among patients with treatment-resistant depression

BACKGROUND

Patients with depression can be mistakenly labeled as treatment-resistant if they fail to receive an adequate first-line antidepressant trial. Adding second-line agents to the treatment regimens can create an additional burden on both the patients and the healthcare system.

OBJECTIVES

To determine if depressed patients receive an adequate antidepressant trial prior to starting second-line therapy and to investigate the association between the type of second-line treatment and severity of illness or depression among unipolar versus bipolar patients.

SETTING

Oklahoma Medicaid claims data between 2006 and 2011.

METHODS

Subjects were depression-diagnosed adult patients with at least two prescriptions of antidepressants followed by a second-line agent. Patients were categorized into one of three groups: an atypical antipsychotic, other augmentation agents (lithium, buspirone, and triiodothyronine), or adding antidepressants, based on the type of second-line therapy. An adequate trial was defined per the American Psychiatric Association guidelines. Factors associated with the type of treatment were tested using multinomial logistic regression models stratified by type of depression (unipolar vs. bipolar patients).

MAIN OUTCOME MEASURE

Variables used to measure receiving an adequate antidepressant trial included: trial duration, adherence, dose adequacy, and number of distinct antidepressant trials.

RESULTS

A total of 3910 patients were included in the analysis. Most subjects reached the recommended antidepressant dose. However, 28 % of patients had an antidepressant trial duration <4 weeks and only 60 % tried at least two antidepressant regimens prior to adding second-line therapy. Approximately 50 % of the subjects were non-adherent across all groups. Severity of illness and receipt of an adequate antidepressant trial were not predictors of the type of second-line treatment.

CONCLUSION

Many patients do not receive an adequate antidepressant trial before starting a second-line agent. The type of second-line treatment was independent of severity of depression. These findings support policies that require reviewing the recommended dose and duration of the first-line antidepressant before adding second-line agents. Healthcare providers need to review the patient's history and reconsider the evidence for prescribing second-line agents.

Starting antidepressant use: a qualitative synthesis of UK and Australian data

OBJECTIVE

To explore people's experiences of starting antidepressant treatment.

DESIGN

Qualitative interpretive approach combining thematic analysis with constant comparison. Relevant coding reports from the original studies (generated using NVivo) relating to initial experiences of antidepressants were explored in further detail, focusing on the ways in which participants discussed their experiences of taking or being prescribed an antidepressant for the first time.

PARTICIPANTS

108 men and women aged 22-84 who had taken antidepressants for depression.

SETTING

Respondents recruited throughout the UK during 2003-2004 and 2008 and 2012-2013 and in Australia during 2010-2011.

RESULTS

People expressed a wide range of feelings about initiating antidepressant use. People's attitudes towards starting antidepressant use were shaped by stereotypes and stigmas related to perceived drug dependency and potentially extreme side effects. Anxieties were expressed about starting use, and about how long the antidepressant might begin to take effect, how much it might help or hinder them, and about what to expect in the initial weeks. People worried about the possibility of experiencing adverse effects and implications for their senses of self. Where people felt they had not been given sufficient time during their consultation information or support to take the medicines, the uncertainty could be particularly unsettling and impact on their ongoing views on and use of antidepressants as a viable treatment option.

CONCLUSIONS

Our paper is the first to explore in-depth patient existential concerns about start of antidepressant use using multicountry data. People need additional support when they make decisions about starting antidepressants. Health professionals can use our findings to better understand and explore with patients' their concerns before their patients start antidepressants. These insights are key to supporting patients, many of whom feel intimidated by the prospect of taking antidepressants, especially during the uncertain first few weeks of treatment.

Why underserved patients do not consult their general practitioner for depression: results of a qualitative and a quantitative survey at a free outpatient clinic in Paris, France

BACKGROUND

The prevalence of depression in the general population is 5 to 10% but can exceed 50% in the most socially vulnerable populations. The perceptions of this disease are widely described in the literature, but no research has been carried out in France to explain the reasons for not consulting a general practitioner during a depressive episode, particularly in people in the most precarious situations. The objective of this study was to describe the reasons for not seeking primary care during a depressive episode in a socially vulnerable population.

METHODS

An exploratory sequential design with a preliminary qualitative study using a phenomenological approach. Subsequently, themes that emerged from the qualitative analysis were used in a questionnaire administered in a cross-sectional observational study at a free outpatient clinic in Paris in 2010. Lastly, a logistic regression analysis was performed.

RESULTS

The qualitative analysis revealed four aspects that explain the non-consulting of a general practitioner during a depressive episode: the negative perception of treatment, the negative perception of the disease, the importance of the social environment, and the doctor-patient relationship. The quantitative analysis showed that close to 60% of the patients who visited the free clinic were depressed and that only half of them had talked with a care provider. The results of the statistical analysis are in line with those of the qualitative analysis, since the most common reasons for not seeing a general practitioner were the negative perception of the disease (especially among the men and foreigners) and its treatments (more often among the men and French nationals).

CONCLUSIONS

Close to 50% of the depressed individuals did not seek primary care during a depressive episode, and close to 80% of them would have liked their mental health to be discussed more often by a health professional. Better information on depression and its treatments, and more-systematic screening by primary care personnel would improve the treatment of depressed patients, especially those in the most precarious situations.

Behavioral activation for depression in older adults: theoretical and practical considerations

Late-life depression (LLD) is a major public health concern that can have devastating effects on older individuals and their families. Behavioral theories predict that decreases in response-contingent positive reinforcement and increases in negatively reinforced avoidance behaviors, often accompanied by aversive life events, result in the selection and maintenance of depression. Based on these theories, behavioral activation treatments for depression are designed to facilitate structured increases in enjoyable activities that increase opportunities for contact with positive reinforcement. We discuss the applicability of behavioral models for LLD, and we briefly review current behavioral activation interventions for LLD with an emphasis on implications for future behavior-analytic research. Behavioral activation has been demonstrated to be effective in reducing depression and increasing healthy behavior in older adults. Potential challenges and considerations for future research are discussed. We suggest that applied behavior analysts and clinical behavior analysts are particularly well suited to improve and expand on the knowledge base and practical application of behavioral activation interventions with this population.

[Attitudes towards anti-depressive therapy: acceptance vs. stigmatization]

OBJECTIVE

The current study investigates the attitude towards antidepressant treatment among general public.

METHODS

A total of 234 probands (139 women and 95 men) were asked to complete individually provided questionnaires examining socio-demographic data, psychoeducational levels, as well as personal beliefs concerning antidepressant treatment and levels of present stigmatisation. Three scales were used to quantify stigmatisation levels-"Revised Perceived Devaluation Discrimination Scale"/"Revised Internalized Stigma of Mental Illness Scale"/"Attitudes Toward Mental Health Treatment Scale", "Revised Perceived Devaluation Discrimination Scale".

RESULTS

65 people (27.8 %) reported to have had one or more episodes of depression during their lifetime; 169 people (72.2 %) indicated to have never had any episode of that type before. The words "sickness" and "anxiety" were the terms primarily associated with the word "depression". It was a common belief among interviewees that lonely individuals or those not receiving social support have a higher risk of becoming depressed. We further found that people experience higher levels of internalized stigma when talking about their antidepressant drug-therapy, than the level of perceived stigma would suggest. Opposed to those not indicating depression depressed people indicated that they considered the use of antidepressant medication helpful and a good option, if necessary. Stigma can still be found among those not indicating depression as well as among those with symptoms of depression. Based on the current study we conclude that work in the field of destigmatisation is of great importance.

Patients' perspectives on antidepressant treatment in consultations with physicians

Patient perspectives on antidepressant treatment and physician attention, and responses toward these in consultations with patients diagnosed with depression, are rarely studied. We analyzed video-recorded consultations with general practitioners (GPs) and psychiatrists. We used conversation analysis and systemic functional linguistics and found that the perspectives patients expressed related to the possibility of achieving, and the inability to retain, a sense of agency. Patients also presented indirect expressions of shame and expressions suggesting alienation toward medical treatment. GPs attended to patient perspectives by talking about medication indirectly. When patients expressed their perspectives, GPs responded by being nonauthoritative but also without prompting patients to elaborate on their reflections. Psychiatrists responded authoritatively and never urged patients to reflect on their perspectives. Shared decision making did not take place because physicians did not explore patients' perspectives in depth or offer their expertise by taking these perspectives into consideration.

Health care providers' perspectives of medication adherence in the treatment of depression: a qualitative study

PURPOSE

Non-adherence to antidepressant medications is a significant barrier to the successful treatment of depression. The purpose of this study was to explore the perspectives of health care providers on antidepressant medication non-adherence in clinical practice.

METHODS

Individual semi-structured interviews were conducted with a purposive sample of 31 health care providers from a range of disciplines and settings in the state of New South Wales, Australia. Interviews focused on medication adherence issues in depression and participants' strategies in addressing them. Interviews were audio recorded, transcribed verbatim and thematically content analyzed using a constant comparison approach.

RESULTS

Participants acknowledged medication non-adherence to be a complex problem in depression, and attributed this problem to patient, medication and environmental-specific issues. Five approaches in addressing non-adherence were reported: patient education, building partnerships with patients, pharmacological management, developing behavioural skills and building supportive networks. Challenges to the management of non-adherence were lack of time and skills, assessment of medication adherence, transition period immediately post-discharge and conflicts in views between providers.

CONCLUSION

Participants were able to identify issues and strategies in addressing antidepressant non-adherence; however, barriers were also identified that could impact on providers' ability to address this issue effectively. More research is needed to develop effective multidisciplinary strategies that take into account providers' perspectives in improving adherence to antidepressant medications.

Predictors of Treatments Acceptable to Patients for Late-Life Depression

Objectives. Describe older patients' perceptions about depression and characteristics associated with acceptance of treatments. Design. Cross-sectional study. Setting. Three primary care clinics in Iowa. Participants. Consecutive sample of 529 primary care patients. Measurements. Depression screening tool (a 9-item patient health questionnaire [PHQ-9]) and questionnaire including sociodemographic data, patient attitudes about depression, and acceptability of different treatments. Results. Mean age was 71.9 years (range 60–93 years), 314 (59%) female. Among the 529 participants, 93 (17.5%) had history of depression and 60 (11.3%) had PHQ-9 scores of 10 or greater. Participants believed depression is a disease for which they would use medication and counseling. Accepting medications from primary physicians was strongly associated with a past history of depression (P < 0.01) and with agreeing that depression needs treatment (P < 0.01). Counseling was not acceptable for those believing that they can control depression on their own (P < 0.01). Older patients (P < 0.001) and those with higher education levels (P < 0.01) were less likely to accept herbs or supplements as treatment options. Willingness to discuss treatments with family was associated with not using alcohol as a treatment and acceptance of all other treatment options (P < 0.001). Conclusions. Attitude that depression is a disease and the willingness to discuss depression with family may enhance treatment acceptance.

What we talk about when we talk about depression: doctor-patient conversations and treatment decision outcomes

BACKGROUND

Efforts to address depression in primary care settings have focused on the introduction of care guidelines emphasising pharmacological treatment. To date, physician adherence remains low. Little is known of the types of information exchange or other negotiations in doctor-patient consultations about depression that influence physician decision making about treatment.

AIM

The study sought to understand conversational influences on physician decision making about treatment for depression.

DESIGN

A secondary analysis of consultation data collected in other studies. Using a maximum variation sampling strategy, 30 transcripts of primary care consultations about distress or depression were selected from datasets collected in three countries. Transcripts were analysed to discover factors associated with prescription of medication.

METHOD

The study employed two qualitative analysis strategies: a micro-analysis approach, which examines how conversation partners shape the dialogue towards pragmatic goals; and a narrative analysis approach of the problem presentation.

RESULTS

Patients communicated their conceptual representations of distress at the outset of each consultation. Concepts of depression were communicated through the narrative form of the problem presentation. Three types of narratives were identified: those emphasising symptoms, those emphasising life situations, and mixed narratives. Physician decision making regarding medication treatment was strongly associated with the form of the patient's narrative. Physicians made few efforts to persuade patients to accept biomedical attributions or treatments.

CONCLUSION

Results of the study provide insight into why adherence to depression guidelines remains low. Data indicate that patient agendas drive the 'action' in consultations about depression. Physicians appear to be guided by common-sense decision-making algorithms emphasising patients' views and preferences.

How patients understand depression associated with chronic physical disease--a systematic review

BACKGROUND

Clinicians are encouraged to screen people with chronic physical illness for depression. Screening alone may not improve outcomes, especially if the process is incompatible with patient beliefs. The aim of this research is to understand people's beliefs about depression, particularly in the presence of chronic physical disease.

METHODS

A mixed method systematic review involving a thematic analysis of qualitative studies and quantitative studies of beliefs held by people with current depressive symptoms. MEDLINE, EMBASE, PSYCHINFO, CINAHL, BIOSIS, Web of Science, The Cochrane Library, UKCRN portfolio, National Research Register Archive, Clinicaltrials.gov and OpenSIGLE were searched from database inception to 31st December 2010. A narrative synthesis of qualitative and quantitative data, based initially upon illness representations and extended to include other themes not compatible with that framework.

RESULTS

A range of clinically relevant beliefs was identified from 65 studies including the difficulty in labeling depression, complex causal factors instead of the biological model, the roles of different treatments and negative views about the consequences of depression. We found other important themes less related to ideas about illness: the existence of a self-sustaining 'depression spiral'; depression as an existential state; the ambiguous status of suicidal thinking; and the role of stigma and blame in depression.

CONCLUSIONS

Approaches to detection of depression in physical illness need to be receptive to the range of beliefs held by patients. Patient beliefs have implications for engagement with depression screening.

Under-treatment of depression in older persons

BACKGROUND

Due to the cross-sectional design of most existing studies, longitudinal characterization of treatment for depression in older persons is largely unknown.

METHOD

Seven hundred fifty-four men and women (aged 70+ years) underwent monthly assessments of mental health professional use and 18-month assessments of antidepressant medication use and depressive symptoms over 9 years. Scores of ≥20 on the Center for Epidemiological Studies-Depression (CES-D) scale denoted depression. We evaluated trends in depression treatment over time in the entire sample and among the depressed participants. Using generalized linear models, we determined characteristics associated with receiving treatment for depression in these groups and among those with persistent depression.

RESULTS

During the 9-year follow-up period (1998-2007), 339 (45.0%) of the participants reported depression treatment. Over time, antidepressant use alone decreased (p trend<0.001) while treatment with both antidepressants and a mental health professional increased (p trend=0.002). Of the 286 (27.9%) depressed participants, between 43% and 69% did not receive depression treatment during any 18-month interval. 30.5% of the 121 participants with persistent depression did not receive treatment during the study period. Increasing number of years of education, decreasing cognitive status score, and being physically frail were associated with a higher likelihood of receiving treatment in all models.

LIMITATIONS

Pre-baseline depression, pre-baseline treatment, and indication for treatment were unavailable.

CONCLUSIONS

Our findings indicate that the profile of treatment for depression in older persons has changed over time, that depressed older persons, including those with persistent depression, are under-treated, and that patient characteristics influence receipt of treatment.

Prevalence of anxiety and its correlates among older adults in Latin America, India and China: cross-cultural study

BACKGROUND

Anxiety is a common mental disorder among older people who live in the Western world, yet little is known about its prevalence in low- and middle-income countries.

AIMS

We investigated the prevalence of anxiety and its correlates among older adults in low- and middle-income countries with diverse cultures.

METHOD

Cross-sectional surveys of all residents aged 65 or over (n = 15 021) in 11 catchment sites in 7 countries (China, India, Cuba, Dominican Republic, Venezuela, Mexico and Peru) were carried out as part of the 10/66 collaboration. Anxiety was measured by using the Geriatric Mental State Examination (GMS) and the Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) diagnostic algorithm.

RESULTS

The age- and gender-standardised prevalence of anxiety varied greatly across sites, ranging from 0.1% (95% CI 0.0-0.3) in rural China to 9.6% (95% CI 6.2-13.1) in urban Peru. Urban centres had higher estimates of anxiety than their rural counterparts with adjusted (age, gender and site) odds ratios of 2.9 (95% CI 1.7-5.3). Age, gender, socioeconomic status and comorbid physical illnesses were all associated with a GMS/AGECAT diagnosis of anxiety, and so was disability (World Health Organization Disability Assessment Schedule II).

CONCLUSIONS

Anxiety is common in Latin America. Estimates from this region are similar to the ones from high-income European countries found in the literature. As demographic change will occur more rapidly in these countries, further research exploring the mental health of older people in developing areas is vital, with the inclusion of other specific anxiety disorders, along with evidence for strategies for supporting those with these disorders.

Acupuncture for the treatment of major depressive disorder: a randomized controlled trial

BACKGROUND

Over 50% of patients with major depressive disorder (MDD) either do not tolerate or do not respond to antidepressant medications. Several preliminary studies have shown the benefits of acupuncture in the treatment of depression. We sought to determine whether a 2-point electroacupuncture protocol (verum acupuncture) would be beneficial for MDD, in comparison to needling at nonchannel scalp points with sham electrostimulation (control acupuncture).

METHOD

Fifty-three subjects aged 18-80 years, recruited via advertisement or referral, were included in the primary analysis of our randomized controlled trial, which was conducted from March 2004 through May 2007 at UPMC Shadyside, Center for Complementary Medicine, in Pittsburgh, Pennsylvania. Inclusion criteria were mild or moderate MDD (according to the Structured Clinical Interview for DSM-IV Axis I Disorders) and a score of 14 or higher on the Hamilton Depression Rating Scale (HDRS). Exclusion criteria included severe MDD, seizure disorder or risk for seizure disorder, psychosis, bipolar disorder, chronic MDD, treatment-resistent MDD, and history of substance abuse in the prior 6 months. Patients were randomized to receive twelve 30-minute sessions of verum versus control acupuncture over 6 to 8 weeks. The HDRS was the primary outcome measure. The UKU Side Effect Rating Scale was used to assess for adverse effects.

RESULTS

Twenty-eight subjects were randomized to verum electroacupuncture and 25 to control acupuncture. The 2 groups did not differ with regard to gender, age, or baseline severity of depression. Both groups improved, with mean (SD) absolute HDRS score decreases of -6.6 (5.9) in the verum group and -7.6 (6.6) in the control group, corresponding to 37.5% and 41.3% relative decreases from baseline. There were no serious adverse events associated with either intervention, and endorsement of adverse effects was similar in the 2 groups.

CONCLUSIONS

We were unable to demonstrate a specific effect of electroacupuncture. Electroacupuncture and control acupuncture were equally well tolerated, and both resulted in similar absolute and relative improvement in depressive symptoms as measured by the HDRS.

Shared conceptualizations and divergent experiences of counseling among African American and white older adults

Research findings suggest that older adults prefer counseling for depression treatment; however, few older adults use counseling services. In this article we present the results of our analysis of semistructured interviews with 102 older adults to explore conceptualizations of counseling and impediments to use among African American and White older adults. We found that older adults believe counseling is beneficial; however, use was hindered in multiple ways. Older adults were skeptical about establishing a caring relationship with a professional. African American older adults did not mention social relationships to facilitate depression care, whereas White older adults described using personal relationships to navigate counseling services. African American older men were least familiar with counseling. Our findings suggest that African American and White older adults share a strong cultural model of counseling as beneficial; however, significant impediments exist and affect older adults differentially based on ethnicity.

Patient preferences for treatment of major depressive disorder and the impact on health outcomes: a systematic review

OBJECTIVE

To summarize the peer-reviewed literature on patient preferences for depression treatments and the impact of these preferences on the outcomes of treatment.

DATA SOURCES

Studies were identified via a systematic search conducted simultaneously in PsycINFO and MEDLINE using EBSCOhost and EMBASE. Publications were retrieved in March 2010.

STUDY SELECTION

Search terms included depression OR MDD OR major depressive disorder, patient preference, treatment preference, intervention preference, and pharmacotherapy preference. There were no restrictions on years of publication. The search was restricted to research articles written in English.

DATA EXTRACTION

Fifteen articles contained unique information on patient preferences for depression treatments and their impact on depression-related outcomes.

RESULTS

The patient preference literature includes a limited number of studies examining the impact of patient preferences on outcomes such as depression severity, treatment initiation, persistence and adherence, treatment engagement, the development of the therapeutic alliance, and health-related quality of life. The majority of the preference research has focused on comparisons of psychotherapy versus pharmacotherapy, with some limited information regarding comparisons of psychotherapies. Results from the research to date suggest that the impact of patient treatment preferences is mixed. The results also indicate that patient preferences have minimal impact on depression severity outcomes within the context of controlled clinical trials but may be more strongly associated with other outcomes such as entry into treatment and development of the therapeutic alliance. However, it is important to note that the literature is limited in that the impact of patient preference has been examined only through secondary analyses, and there have been few studies designed explicitly to examine the impact of patient preferences, particularly outside the context of controlled clinical trials.

CONCLUSIONS

Consideration of patient preferences for depression treatments may lead to increased treatment initiation and improved therapeutic alliance. However, despite treatment guidelines and suggestions in the literature, the value of and appropriate procedures for considering patient preferences in real-world treatment decisions deserves more careful study. Further research is needed, and future studies should be conducted in more naturalistic treatment settings that examine patient preferences for other specific approaches to depression treatments including preferences related to comparisons of individual pharmacotherapies and second-step treatments.

Long-term prescribing of antidepressants in the older population: a qualitative study

BACKGROUND

High rates of long-term antidepressant prescribing have been identified in the older population.

AIMS

To explore the attitudes of older patients and their GPs to taking long-term antidepressant therapy, and their accounts of the influences on long-term antidepressant use.

DESIGN OF STUDY

Qualitative study using in-depth semi-structured interviews.

SETTING

One primary care trust in North Bradford.

METHOD

Thirty-six patients aged > or =75 years and 10 GPs were interviewed. Patients were sampled to ensure diversity in age, sex, antidepressant type, and home circumstances.

RESULTS

Participants perceived significant benefits and expressed little apprehension about taking long-term antidepressants, despite being aware of the psychological and social factors involved in onset and persistence of depression. Barriers to discontinuation were identified following four themes: pessimism about the course and curability of depression; negative expectations and experiences of ageing; medicine discontinuation perceived by patients as a threat to stability; and passive (therapeutic momentum) and active (therapeutic maintenance) decisions to accept the continuing need for medication.

CONCLUSION

There is concern at a public health level about high rates of long-term antidepressant prescribing, but no evidence was found of a drive for change either from the patients or the doctors interviewed. Any apprehension was more than balanced by attitudes and behaviours supporting continuation. These findings will need to be incorporated into the planning of interventions aimed at reducing long-term antidepressant prescribing in older people.

WPA guidance on how to combat stigmatization of psychiatry and psychiatrists

In 2009 the WPA President established a Task Force that was to examine available evidence about the stigmatization of psychiatry and psychiatrists and to make recommendations about action that national psychiatric societies and psychiatrists as professionals could do to reduce or prevent the stigmatization of their discipline as well as to prevent its nefarious consequences. This paper presents a summary of the Task Force's findings and recommendations. The Task Force reviewed the literature concerning the image of psychiatry and psychiatrists in the media and the opinions about psychiatry and psychiatrists of the general public, of students of medicine, of health professionals other than psychiatrists and of persons with mental illness and their families. It also reviewed the evidence about the interventions that have been undertaken to combat stigma and consequent discrimination and made a series of recommendations to the national psychiatric societies and to individual psychiatrists. The Task Force laid emphasis on the formulation of best practices of psychiatry and their application in health services and on the revision of curricula for the training of health personnel. It also recommended that national psychiatric societies establish links with other professional associations, with organizations of patients and their relatives and with the media in order to approach the problems of stigma on a broad front. The Task Force also underlined the role that psychiatrists can play in the prevention of stigmatization of psychiatry, stressing the need to develop a respectful relationship with patients, to strictly observe ethical rules in the practice of psychiatry and to maintain professional competence.

Collaborative depression treatment in older and younger adults with physical illness: pooled comparative analysis of three randomized clinical trials

OBJECTIVE

There have been few comparisons of the effectiveness of collaborative depression care between older versus younger adults with comorbid illness, particularly among low-income populations.

DESIGN

Intent-to-treat analyses are conducted on pooled data from three randomized controlled trials that tested collaborative care aimed at improving depression, quality of life, and treatment receipt.

SETTINGS

Trials were conducted in oncology and primary care safety net clinics and diverse home healthcare programs.

PARTICIPANTS

Thousand eighty-one patients with major depressive symptoms and cancer, diabetes, or other comorbid illness.

INTERVENTION

Similar intervention protocols included patient, provider, sociocultural, and organizational adaptations.

MEASUREMENTS

The Patient Health Questionnaire (PHQ)-9 depression, Short-Form Health Survey-12/20 quality of life, self-reported hospitalization, ER, intensive care unit utilization, and antidepressant, psychotherapy treatment receipt are assessed at baseline, 6, and 12 months.

RESULTS

There are no significant differences in reducing depression symptoms (p ranged 0.18-0.58), improving quality of life (t = 1.86, df = 669, p = 0.07 for physical functioning at 12 months, and p ranged 0.23-0.99 for all others) patients aged between >/=60 years versus 18-59 years. Both age group intervention patients have significantly higher rates of a 50% PHQ-9 reduction (older: Wald chi[df = 1] = 4.82, p = 0.03; younger: Wald chi[df = 1] = 6.47, p = 0.02), greater reduction in major depression rates (older: Wald chi[df = 1] = 7.72, p = 0.01; younger: Wald chi[df = 1] = 4.0, p = 0.05) than enhanced-usual-care patients at 6 months and no significant age group differences in treatment type or intensity.

CONCLUSION

Collaborative depression care in individuals with comorbid illness is as effective in reducing depression in older patients as younger patients, including among low-income, minority patients. Patient, provider, and organizational adaptations of depression care management models may contribute to positive outcomes.

Treatment preference, engagement, and clinical improvement in pharmacotherapy versus psychotherapy for depression

Pharmacotherapy and psychotherapy are generally effective treatments for major depressive disorder (MDD); however, research suggests that patient preferences may influence outcomes. We examined the effects of treatment preference on attrition, therapeutic alliance, and change in depressive severity in a longitudinal randomized clinical trial comparing pharmacotherapy and psychotherapy. Prior to randomization, 106 individuals with MDD reported whether they preferred psychotherapy, antidepressant medication, or had no preference. A mismatch between preferred and actual treatment was associated with greater likelihood of attrition, fewer expected visits attended, and a less positive working alliance at session 2. There was a significant indirect effect of preference match on depression outcomes, primarily via effects of attendance. These findings highlight the importance of addressing patient preferences, particularly in regard to patient engagement, in the treatment of MDD.

Early discontinuation of antidepressant treatment and suicide risk among persons aged 50 and over: a population-based register study

BACKGROUND

As many as 47% of adults over age 50 discontinue treatment with antidepressants after redeeming only one prescription. The study aim was to assess the risk of suicide in adults aged 50+ who discontinue antidepressants at an early stage of treatment.

METHOD

Case control study of all individuals aged 50+ living in Denmark and who initiated antidepressant treatment between July 1st 1995 and December 31st 2000 (N=217,123). Hazard ratios were calculated using Cox regression analyses, propensity score matching techniques, and marginal structural models.

RESULTS

During the study period, 78,594 men and 138,529 women aged 50+ began treatment with an antidepressant medication, of whom 309 men and 229 women died by suicide. Men aged 50+ who discontinued treatment early had a suicide rate of 167 per 100,000 compared with 175 per 100,000 in those who continued refilling prescriptions; hazard ratio=0.98 [CI-95%: 0.78-1.23]. The suicide rate in women who discontinued treatment was 52 per 100,000 compared with 74 per 100,000 in those who continued refilling; hazard ratio=0.72 [CI-95%: 0.55-0.94]. Although people with previous psychiatric hospitalizations had greater risk of suicide than those without past hospital admissions, the difference was not significant in the adjusted model.

LIMITATIONS

Prescriptions redeemed at pharmacies are our only indicator of treatment adherence. Also, information on severity of depression was not available.

CONCLUSIONS

We did not find a lower suicide risk among people over age 50 who seemingly follow treatment in comparison with those who discontinued treatment with antidepressants at an early stage.

Behavioral intervention to promote smoking cessation and prevent weight gain: a systematic review and meta-analysis

AIMS

The prospect of weight gain discourages many cigarette smokers from quitting. Practice guidelines offer varied advice about managing weight gain after quitting smoking, but no systematic review and meta-analysis have been available. We reviewed evidence to determine whether behavioral weight control intervention compromises smoking cessation attempts, and if it offers an effective way to reduce post-cessation weight gain.

METHODS

We identified randomized controlled trials (RCTs) that compared combined smoking treatment and behavioral weight control to smoking treatment alone for adult smokers. English-language studies were identified through searches of PubMed, Ovid MEDLINE, CINAHL, EMBASE, PsycINFO and Cochrane Central Register of Controlled Trials. Of 779 articles identified and 35 potentially relevant RCTs screened, 10 met the criteria and were included in the meta-analysis.

RESULTS

Patients who received both smoking treatment and weight treatment showed increased abstinence [odds ratio (OR) = 1.29, 95% confidence interval (CI) = 1.01, 1.64] and reduced weight gain (g = -0.30, 95% CI = -0.57, -0.02) in the short term (<3 months) compared with patients who received smoking treatment alone. Differences in abstinence (OR = 1.23, 95% CI = 0.85, 1.79) and weight control (g = -0.17, 95% CI = -0.42, 0.07) were no longer significant in the long term (>6 months).

CONCLUSIONS

Findings provide no evidence that combining smoking treatment and behavioral weight control produces any harm and significant evidence of short-term benefit for both abstinence and weight control. However, the absence of long-term enhancement of either smoking cessation or weight control by the time-limited interventions studied to date provides insufficient basis to recommend societal expenditures on weight gain prevention treatment for patients who are quitting smoking.

Antidepressant adherence after psychiatric hospitalization among VA patients with depression

Depressed patients discharged from psychiatric hospitalizations face increased risks for adverse outcomes including suicide, yet antidepressant adherence rates during this high-risk period are unknown. Using Veterans Affairs (VA) data, we assessed antidepressant adherence and predictors of poor adherence among depressed veterans following psychiatric hospitalization. We identified VA patients nationwide with depressive disorders who had a psychiatric hospitalization between April 1, 1999 and September 30, 2003, received antidepressant medication, and had an outpatient appointment following discharge. We calculated medication possession ratios (MPRs), a measure of medication adherence, within 3 and 6 months following discharge. We assessed patient factors associated with having lower levels of adherence (MPRs < 0.8) after discharge. The criteria for 3- and 6-month MPRs were met by 20,931 and 23,182 patients respectively. The mean 3 month MPR was 0.79 (SD = 0.37). The mean 6 month MPR was 0.66 (SD = 0.40). Patients with poorer adherence were male, younger, non-white, and had a substance abuse disorder, but were less likely to have PTSD or other anxiety disorders. Poor antidepressant adherence is common among depressed patients after psychiatric hospitalization. Efforts to improve adherence at this time may be critical in improving the outcomes of these high-risk patients.

Primary-care patients' expectations and experiences of online cognitive behavioural therapy for depression: a qualitative study

OBJECTIVE

To explore expectations and experiences of online cognitive behavioural therapy (CBT) among primary-care patients with depression, focusing on how this mode of delivery impacts upon the therapeutic experience.

DESIGN

Qualitative study, using repeat semi-structured interviews with patients before and after therapy. The study was conducted in parallel with a randomized controlled trial examining the effectiveness and cost-effectiveness of online CBT for patients with depression.

PARTICIPANTS

Twenty-four patients with depression recruited from five general practices in southwest England, who were offered up to 10 sessions of CBT, delivered via the internet by a psychologist.

RESULTS

Most participants accessed the therapy from their home computer and found this to be a major advantage, in terms of convenience and fitting therapy into their daily routine, with any technical problems quickly resolved. Two key themes regarding expectations and experiences of online CBT were: developing a virtual relationship with a therapist, and the process of communicating thoughts and emotions via an online medium. Online CBT seems to be acceptable to, and experienced as helpful by, certain subgroups of patients with depression, particularly those who are familiar with computers, feel comfortable with writing their feelings down, enjoy the opportunities to review and reflect that written (or typed) communication offers are attracted to the 'anonymity' of an online therapeutic relationship and are open to the proactive requirements of CBT itself. However, on-line CBT may feed into the vulnerability of depressed people to negative thoughts, given the absence of visual cues and the immediate response of face-to-face interaction.

CONCLUSIONS

Online CBT has the potential to enhance care for patients with depression who are open to engaging in 'talking' (or typing) therapies as part of their treatment. If online CBT is to be provided via the NHS, it is important to establish patient preferences regarding this mode of delivery and ensure that referral practices are appropriately targeted. The results of our main trial will provide evidence regarding the effectiveness and cost-effectiveness of receiving therapy via this modality.

Older primary care patient views regarding antidepressants: A mixed methods approach

BACKGROUND: Generally, the efforts to predict antidepressant use from patient demographic factors have not been fruitful. AIM: Our objective was to generate hypotheses regarding antidepressant use among older primary care patients. METHODS: We utilized a mixed methods design that is both hypothesis-testing and hypothesis-generating. Adults aged 65 years and over were recruited from primary care practices and interviewed in their homes. We examined the personal characteristics of older adults according to antidepressant use (hypothesis-testing). Participants taking antidepressants and participants not taking antidepressants were asked open-ended questions about their views on treatment for depression. Themes related to use of antidepressants were examined (hypothesis-generating). RESULTS: Older adults taking antidepressants were more likely to be white and have more depression symptoms compared to older adults not taking antidepressants (p < 0.001 and p = 0.004, respectively). Positive and negative themes emerged when participants discussed antidepressant use. We linked quantitative data from the participants with the themes they endorsed to form an emerging theory about older adults' perceptions about antidepressant use. CONCLUSION: Few personal characteristics were associated with aatidepressant use. An improved understanding of how older adults view antidepressant use, derived from multiple methods, may inform clinical practice.

Untangling the complexities of depression diagnosis in older cancer patients

This review article discusses the complexities of diagnosing depression in older, geriatric cancer patients. There has been little research conducted with this population on the assessment, recognition, and treatment of depression, and thus increased attention is required to improve care for these individuals. Depressive symptoms often manifest themselves differently in both cancer patients and older patients, and therefore a modified and adapted way of assessment must be employed when thinking about diagnosing and treating these patients.

Making fewer depression diagnoses: beneficial for patients?

Currently, general practitioners actively search for depressive disorders in their patients. When they diagnose 'depressive disorder', they tell their patients that they have a disease and can be treated accordingly. This is probably an important reason for the huge prescription rates of anti-depressants. In doing so, general practitioners implement specialised, psychiatric diagnostic methods in a setting characterised by patients with symptoms that superficially may resemble those of depressive disorder but in reality mainly arise from normal problems in everyday life due to losses of valued relations or failure to achieve desired goals. We argue that it might be beneficial for patients if general practitioners, in a stepped care approach, hold back on specialised methods of psychiatry and instead use a more generalist approach as first step, in which patients' problems are formulated in their own words, and efforts are directed in helping patients regain their self-confidence to solve them. Our arguments for directing attention away from diagnosing depressive disorder are: depressive disorder is a diagnosis by agreement and therefore relative, so there are other ways to look at problems than though psychiatric glasses; depression has unclear boundaries with other mental disorders and with normality; depression is often not an adequate summary of the real problems of the patient; the patient often has a very different conception about what is wrong and often does not agree with the proposed presence of a mental disorder; to diagnose depressive disorder may have more disadvantages than advantages for the patient;. the efficacy of anti-depressants is very modest.

The development of valid subtypes for depression in primary care settings: a preliminary study using an explanatory model approach

A persistent theme in the debate on the classification of depressive disorders is the distinction between biological and environmental depressions. Despite decades of research, there remains little consensus on how to distinguish between depressive subtypes. This preliminary study describes a method that could be useful, if implemented on a larger scale, in the development of valid subtypes of depression in primary care settings, using explanatory models of depressive illness. Seventeen depressed Hispanic patients at an inner city general practice participated in explanatory model interviews. Participants generated illness narratives, which included details about symptoms, cause, course, impact, health seeking, and anticipated outcome. Two distinct subtypes emerged from the analysis. The internal model subtype was characterized by internal attributions, specifically the notion of an "injured self." The external model subtype conceptualized depression as a reaction to life situations. Each subtype was associated with a distinct constellation of clinical features and health seeking experiences. Future directions for research using explanatory models to establish depressive subtypes are explored.

Explaining patients' beliefs about the necessity and harmfulness of antidepressants

PURPOSE

Patients' beliefs about antidepressants vary widely and probably influence adherence, yet little is known about what underlies such beliefs. This study's objective was to identify the demographic and clinical characteristics that account for patients' beliefs about antidepressants.

METHODS

Participants were 165 patients with unipolar nonpsychotic major depression from primary care and psychiatry clinics who were participating in the baseline phase of a multistaged trial of medication and psychotherapy. Before patients started antidepressants, interview and self-report measures were used to assess treatment beliefs, depression features, and comorbid conditions. Linear multivariate regression was used to identify the strongest correlates of perceived medication necessity and harmfulness after adjusting for age, sex, education, and the random effects of patients within clinical site.

RESULTS

Perceived necessity was associated with older age (P <.001), more severe symptoms (P = .03), longer anticipated duration of symptoms (P=.001), and attribution of symptoms to chemical imbalance (P=.005). Perceived harmfulness was highest among patients who had not taken antidepressants before (P = .02), attributed their symptoms to random factors (P=.04), and had a subjectively unclear understanding of depression (P = .003). Neither belief was significantly associated with sex, education, age at first depressive episode, presence of melancholia or anxiety, psychiatric comorbidity, or clinical setting.

CONCLUSIONS

Skepticism about antidepressants is strongest among younger patients who have never taken antidepressants, view their symptoms as mild and transient, and feel unclear about the factors affecting their depression. Perhaps these patients would benefit the most from adherence promotion focusing on treatment beliefs.
