The decision to continue or discontinue treatment: experiences and beliefs of users of selective serotonin-reuptake inhibitors in the initial months--a qualitative study

Pharmacovigilance monitoring and treatment adherence in patients on antihypertensive drugs at a tertiary care centre

Background

Hypertension is one of the main factors contributing to the global burden of non-communicable diseases. Previous research has revealed that stress, bad lifestyle choices and a lack of knowledge about the disease are the main causes of hypertension that can be controlled. The key cause behind the prevalence of the condition is the lack of medication adherence by patients. This study aims to evaluate medication adherence in patients with hypertension through the Morisky Medication Adherence Scale (MMAS) and to observe any adverse drug reaction leading to non-adherence of medications.

Methods

A descriptive, cross-sectional study was conducted on 124 patients who attended the outpatient department of medicine. The descriptive tools were MMAS and causality scales for adverse drug reactions.

Result

The mean MMAS score was 5.20±1.29. Amongst the demographic profile, age, sex, comorbidities and duration of disease were significantly associated with decreased mean MMAS scores. Forty-two patients experienced drug reactions and only four patients were adherent to their medications.

Conclusion

Our study suggests that patients were poorly adherent to their medications. Effective interventions should be considered to improve adherence in patients. Monitoring for adverse drug reactions can lead to improved patient outcomes, whilst interventions to improve adherence can lead to better blood pressure control and reduced risk of cardiovascular events.

Experience of choice of treatment for adults with depression: a systematic review and meta-synthesis of qualitative research

BACKGROUND

Treatment choices for depression are preference-sensitive (no "single best option"). However, factors or attributes that can enhance or inhibit patient choice have not been fully explored.

AIMS

To synthesize the qualitative literature on facilitators and barriers to treatment choice, from the perspective of people with depression and healthcare practitioners.

METHODS

A systematic literature search identified eligible qualitative studies (Protocol registration no. CRD42019151352). Findings from 56 studies were meta-synthesized using a thematic analysis approach.

RESULTS

Overarching facilitators to treatment choice that resonated with both patients and healthcare practitioners included: a trusting and respectful patient-practitioner relationship; information and guidance tailored to the individual and their preferred level of involvement in the decision-making process; eliciting and incorporating patient preferences and individual needs in order to find the best patient-treatment match. Prominent barriers to treatment choice that emerged were: limited time available to explore treatment options; inadequate mental health training, knowledge, skills, and experience; lack of psychological treatment services and waiting times; inflexibility of services.

CONCLUSIONS

By focusing on the factors identified, practitioners can facilitate patient participation in decision-making, which has the potential to improve engagement with treatment and outcomes for adults with depression.

Understanding Australian general practice patients' decisions to deprescribe antidepressants in the WiserAD trial: a realist informed approach

OBJECTIVES

To evaluate how an approach to antidepressant deprescribing works, for whom, and in what contexts by (1) examining the experiences and perceptions of the approach for antidepressant users, (2) identifying the mechanisms of the approach and (3) describing what contexts are associated with antidepressant tapering.

DESIGN

This mixed methods study was informed by the principles of realist evaluation and was conducted in the first 3 months of participation in the WiserAD randomised control trial.

SETTING

General practice, Victoria, Australia.

PARTICIPANTS

13 antidepressant users from general practice participating in the WiserAD trial for antidepressant deprescribing.

INTERVENTION

A patient-facing, web-based structured support tool that consists of a personalised tapering schedule, an action plan for managing withdrawal symptoms, a daily mood, sleep and activity tracker and mental health nurse support.

PRIMARY/SECONDARY OUTCOME MEASURES

The outcomes of the study were revealed on data analysis as per a realist evaluation approach which tests and refines an initial programme theory.

RESULTS

The contexts of learnt coping skills, knowledge and perceptions of antidepressants and feeling well were evident. Outcomes were intention to commence, initiation of deprescribing and successful completion of deprescribing. Key mechanisms for antidepressant deprescribing were (1) initiation of the deprescribing discussion; (2) patient self-efficacy; (3) provision of structured guidance; (4) coaching; (5) mood, sleep and activity tracking and (6) feelings of safety during the tapering period.

CONCLUSIONS

The WiserAD approach to antidepressant deprescribing supported participants to commence and/or complete tapering. The refined programme theory presents the WiserAD pragmatic framework for the application of antidepressant deprescribing in clinical practice.

Patient Perceived Barriers and Enablers to Medication Adherence in the Treatment of Depression: A Qualitative Study

BACKGROUND

Depression affects approximately 280 million individuals globally and it is a leading cause of disability. Despite effective medication options, 50% of patients prematurely discontinue antidepressants within 6 months. We sought to understand patients' perspectives regarding their needs and expectations related to antidepressants.

OBJECTIVES

To identify and describe enablers and barriers that influence adult patients' medication adherence in depression treatment and to explore patients' educational needs on initiating or continuing antidepressant therapy.

METHODS

Qualitative descriptive study was conducted using individual, semi-structured interviews of adult patients with depression who were prescribed an antidepressant within 3 months of study recruitment at an urban primary care clinic in Toronto, Canada. Thirteen participants were interviewed. Interviews were recorded and transcribed verbatim for inductive thematic analysis.

RESULTS

Six themes emerged: safety and effectiveness of antidepressant, understanding of depression and its management, medication administration, healthcare experiences in the treatment of depression, and social influences and relationships. Barriers to adherence included adverse effects of antidepressants, preference for non-pharmacological therapies, uncertainty about therapeutic effects, and social stigma. In contrast, enablers were positive responses from antidepressants, fear of relapse, reminder aids, established routine, and a trusting patient-provider relationship. Participants desired access to reliable, evidence-based, and personalized educational information delivered through verbal, written, and digital formats to support antidepressant adherence.

CONCLUSION

To overcome the identified barriers, educational strategies should involve both patients and their prescribers to identify patient-specific needs and treatment goals, engage in shared decision-making, and maintain consistent follow-up to support antidepressant adherence.

A mixed-methods review and meta-synthesis of fears of recurrence and progression in people with mental health conditions

A fear that one's physical illness will recur or worsen has received substantial research attention over the past decade, most notably as fear of cancer recurrence. Indeed, such fear is known to be associated with poorer quality of life, adjustment, and psychopathology. However, fear of a recurrence or progression (FORP) of mental health conditions has received comparatively little study. The present review aimed to, 1) systematically review quantitative research on FORP in mental health regarding its association with age, gender, quality of life, mental health outcomes, and health behaviours, and 2) meta-synthesize qualitative research related to FORP to construct a transdiagnostic model. A qualitative meta-synthesis of 19 studies identified four subthemes underlying FORP (fear of symptoms, loss of progress, fear of death, and traumatic experiences). The three themes related to FORP were: inability to trust oneself, hypervigilance, and a low-risk low-reward lifestyle which was comprised of three subthemes (limiting relationships, limiting life goals, and fear of changing treatment). A quantitative systematic review of 15 studies found that FORP was strongly associated with worse quality of life, and greater depression, anxiety, psychotic symptoms, and medication adherence, but was not associated with age or gender. Hence, FORP can be understood transdiagnostically, and is generally associated with poorer mental health outcomes but may also predict adaptive health behaviours, such as appropriate medication adherence.

Disentangling pharmacological and expectation effects in antidepressant discontinuation among patients with fully remitted major depressive disorder: study protocol of a randomized, open-hidden discontinuation trial

BACKGROUND

Antidepressants are established as an evidence-based, guideline-recommended treatment for Major Depressive Disorder. Prescriptions have markedly increased in past decades, with a specific surge in maintenance prescribing. Patients often remain on antidepressants longer than clinically necessary. When attempting to stop, many patients experience adverse discontinuation symptoms. Discontinuation symptoms can be debilitating and hinder successful discontinuation. While discontinuation symptoms can result from pharmacological effects, evidence on nocebo-induced side effects of antidepressant use suggests that patients' expectations may also influence occurrence.

METHODS

To disentangle pharmacological and expectation effects in antidepressant discontinuation, patients with fully remitted Major Depressive Disorder who fulfill German guideline recommendations to discontinue will either remain on or discontinue their antidepressant. Participants' expectations will be manipulated by varying verbal instructions using an open-hidden paradigm. Within the open trial arms, participants will receive full information about treatment, i.e., high expectation. Within the hidden trial arms, participants will be informed about a 50% chance of discontinuing versus remaining on their antidepressant, i.e., moderate expectation. A total of N = 196 participants will be randomly assigned to either of the four experimental groups: open discontinuation (OD; n = 49), hidden discontinuation (HD; n = 49), open continuation (OC; n = 49), or hidden continuation (HC; n = 49). Discontinuation symptom load during the 13-week experimental phase will be our primary outcome measure. Secondary outcome measures include discontinuation symptom load during the subsequent 39-week clinical observation phase, recurrence during the 13-week experimental period, recurrence over the course of the complete 52-week trial evaluated in a time-to-event analysis, and stress, anxiety, and participants' attentional and emotional processing at 13 weeks post-baseline. Blood and saliva samples will be taken as objective markers of antidepressant blood serum level and stress. Optional rsfMRI measurements will be scheduled.

DISCUSSION

Until today, no study has explored the interplay of pharmacological effects and patients' expectations during antidepressant discontinuation. Disentangling their effects has important implications for understanding mechanisms underlying adverse discontinuation symptoms. Results can inform strategies to manage discontinuation symptoms and optimize expectations in order to help patients and physicians discontinue antidepressants more safely and effectively.

Self-reported reasons for reducing or stopping antidepressant medications in primary care: thematic analysis of the diamond longitudinal study

BACKGROUND

Current treatment guidelines advise that the deprescribing of antidepressants should occur around 6 months post-remission of symptoms. However, this is not routinely occurring in clinical practice, with between 30% and 50% of antidepressant users potentially continuing treatment with no clinical benefit. To support patients to deprescribe antidepressant treatment when clinically appropriate, it is important to understand what is important to patients when making the decision to reduce or cease antidepressants in a naturalistic setting.

AIM

The current study aimed to describe the self-reported reasons primary care patients have for reducing or stopping their antidepressant medication.

METHODS

Three hundred and seven participants in the diamond longitudinal study reported taking an SSRI/SNRI over the life of the study. Of the 307, 179 reported stopping or tapering their antidepressant during computer-assisted telephone interviews and provided a reason for doing so. A collective case study approach was used to collate the reasons for stopping or tapering.

FINDINGS

Reflexive thematic analysis of patient-reported factors revealed five overarching themes; 1. Depression; 2. Medication; 3. Healthcare system; 4. Psychosocial, and; 5. Financial. These findings are used to inform suggestions for the development and implementation of antidepressant deprescribing discussions in clinical practice.

Experience of antidepressant use and discontinuation: A qualitative synthesis of the evidence

WHAT IS KNOWN ON THE SUBJECT?: Rates of antidepressant prescribing have been increasing. Antidepressants are not effective for many people. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Participants described how in order to receive help they had to engage with a medical pathway in which their experiences were constructed as arising from a biochemical deficit. Antidepressant prescribing was identified as being the only option available and was associated with stigma. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health nurses have a role to play in providing treatment options for those experiencing depression. Mental health nurses need to provide evidence-based information about antidepressants support those experiencing depression to make informed choices. ABSTRACT: Introduction There are increased prescribing rates of antidepressants associated with an increase in the diagnosis of depression. However, antidepressants are not effective for many people. There is a gap in the existing literature for a synthesis of the experiences of those with lived experience of antidepressant use to better understand their use and impact given their ubiquitous use in mental health, primary care and other secondary and tertiary care settings. Mental health nurses play direct or indirect roles in both advocating for antidepressant use and monitoring adherence. Aims To identify how people prescribed antidepressants describe their experiences of the medication including its discontinuation? Method A meta-synthesis of qualitative studies examining patients' experiences of antidepressant medication. Ovid MEDLINE, EMBASE, PsychINFO and Cochrane Library databases were searched in May 2021. One reviewer screened titles and abstracts. Two reviewers independently reviewed the retrieved papers for eligibility and data extraction. The data synthesis was conducted using thematic analysis. Two reviewers independently conducted quality appraisals. Results Twenty-seven studies with a total of 2937 participants were identified for inclusion in this review. Four themes were identified across the studies: the only option available; stigma associated with 'biochemical deficit' not myself and the vicious cycle. Implications for practice Those seeking treatment for depression need to be provided with treatment options and evidence-based information about anti-depressants to provide them with the opportunity to make informed choices.

Polypharmacy and antidepressant acceptability in comorbid depression and type 2 diabetes: a cohort study using UK primary care data

Background

Polypharmacy may increase the risk of drug interactions, side effects, and poor adherence; however, the impact of polypharmacy on antidepressant acceptability in individuals with type 2 diabetes (T2DM) is unknown.

Aim

To investigate the association between number of prescribed medications and early antidepressant discontinuation in adults with T2DM.

Design and setting

Cohort study using UK primary care data from the Clinical Practice Research Datalink between 1 January 2000 and 31 December 2018.

Method

Cox regression with penalised B-splines was used to describe the association between the number of concurrently prescribed medications at the time of starting antidepressant treatment and each of the outcomes.

Results

A total of 73 808 individuals with comorbid depression and T2DM starting antidepressant treatment for the first time were identified. A median of 7 concurrent medications were prescribed. Within 32 weeks, 44.26% (n= 32 665) of participants discontinued antidepressant treatment altogether, and 11.75% (n= 8672) of participants switched antidepressant agents. An inverse relationship between the number of concurrent medications and discontinuing antidepressant treatment altogether was found. The median of 7 concurrent medications was associated with a 65.06% decrease in early antidepressant discontinuation; hazard ratio 0.45, 95% confidence interval = 0.37 to 0.55. No evidence of an association between the number of concurrent medications and switching antidepressant agents was found.

Conclusion

Early discontinuation of antidepressants is common in adults with T2DM; however, individuals with higher levels of concurrent polypharmacy may be more adherent to treatment. These are likely to represent individuals with worse physical or mental health. Individuals with lower levels of concurrent polypharmacy may benefit from adherence support.

Barriers and Facilitating Factors of Adherence to Antidepressant Treatments: An Exploratory Qualitative Study with Patients and Psychiatrists

This study examines the experiences and expectations of patients with depressive disorders regarding the disease and different antidepressants, as well as examining the barriers and facilitating factors that could affect their adherence to medications. An exploratory qualitative study was carried out. The study involved two focus groups made up of patients and caregivers and six semi-structured interviews with psychiatrists. In both cases, the participants were selected by intentional theoretical sampling, seeking maximum significance variation of social types. Prejudice about the side effects of medication was relevant. The importance of patients being well informed about the disease/treatments was noteworthy. The stigmatization of antidepressants by patients was identified as a barrier to medication adherence. The involvement of family members and the motivation of patients to be actively involved in the process to recover from the disease were identified as facilitating factors. The work carried out suggests the need for patients to have rigorous information about the disease/treatment to reduce the possible prejudices generated by beliefs. Maintaining greater contact and monitoring of patients/caregivers to help therapeutic adherence in patients with depressive disorders was also identified as being of great importance.

Factors Contributing to Medication Adherence in Patients with a Chronic Condition: A Scoping Review of Qualitative Research

INTRODUCTION

Medication adherence continues to be a significant challenge in healthcare, and there is a shortage of effective interventions in this area. This scoping review studied the patient-related factors of medication adherence.

METHODS

We searched Medline Ovid, Scopus, and Cochrane Library from January 2009 to June 2021 to find the most recent original qualitative studies or systematic reviews that addressed the patient-related factors of medication adherence in treating chronic conditions. We used the PRISMA-ScR checklist to ensure the quality of the study.

RESULTS

The initial search revealed 4404 studies, of which we included 89 qualitative studies in the scoping review. We inductively organized the patient-related factors causing barriers, as well as the facilitators to medication adherence. The studies more often dealt with barriers than facilitators. We classified the factors as patient-specific, illness-specific, medication-related, healthcare and system-related, sociocultural, as well as logistical and financial factors. Information and knowledge of diseases and their treatment, communication, trust in patient-provider relationships, support, and adequate resources appeared to be the critical facilitators in medication adherence from the patient perspective.

DISCUSSION AND CONCLUSIONS

Patients are willing to discuss their concerns about medications. Better communication and better information on medicines appear to be among the critical factors for patients. The findings of this scoping review may help those who plan further interventions to improve medication adherence.

The Subjective Experience of Using Medications: What We Know and the Paths Forward

Medications can cause bodily changes, where the associated benefits and risks are carefully assessed based on the changes experienced in the phenomenal body. For this reason, the phenomenology of Merleau-Ponty is an important theoretical framework for the study of experience related to the daily use of medications. The aim of this study was to discuss the contribution of a recently developed framework of the general ways people can experience the daily use of medications—resolution, adversity, ambiguity, and irrelevance—and present reflections about the little-understood aspects of this experience. However, some issues raised throughout this article remain open and invite us to further exploration, such as (1) the coexistence of multiple ways of experiencing the use of medications, by the same individual, in a given historical time; (2) the cyclical structure of this experience; (3) the impact of habit and routine on the ways of experiencing the daily use of medications; and (4) the contribution of the concept of existential feelings to this experience and its impact on patients’ decision-making. Therefore, the experience with the daily use of medications is a complex and multifaceted phenomenon that directs the decision-making process of patients, impacting health outcomes.

Reprint of: Psychosocial factors associated with pharmacists' antidepressant drug treatment monitoring

OBJECTIVE

Patients undergoing antidepressant drug treatment (ADT) may face challenges regarding its adverse effects, adherence, and efficacy. Community pharmacists are well positioned to manage ADT-related problems. Little is known about the factors influencing pharmacists' ADT monitoring. This study aimed to identify the psychosocial factors associated with pharmacists' intention to perform systematic ADT monitoring and report on this monitoring.

DESIGN

Cross-sectional study based on the Theory of Planned Behavior (TPB).

SETTING AND PARTICIPANTS

Community pharmacists in the province of Quebec, Canada.

OUTCOME MEASURES

Pharmacists completed a questionnaire on their performance of ADT monitoring, TPB constructs (intention; attitude; subjective norm; perceived behavioral control; and attitudinal, normative, and control beliefs), and professional identity. Systematic ADT monitoring was defined as pharmacists' reporting 4 or more consultations with each patient during the first year of ADT to address adverse effects, adherence, and efficacy. Hierarchical linear regression models were used to identify the factors associated with the intention and reporting of systematic ADT monitoring and Poisson working models to identify the beliefs associated with intention.

RESULTS

A total of 1609 pharmacists completed the questionnaire (participation = 29.6%). Systematic ADT monitoring was not widely reported (mean score = 2.0 out of 5.0), and intention was moderate (mean = 3.2). Pharmacists' intention was the sole psychosocial factor associated with reporting systematic ADT monitoring (P < 0.0001; R² = 0.370). All TPB constructs and professional identity were associated with intention (P < 0.0001; R² = 0.611). Perceived behavioral control had the strongest association.

CONCLUSION

Interventions to promote systematic ADT monitoring should focus on developing a strong intention among pharmacists, which could, in turn, influence their practice. To influence intention, priority should be given to ensuring that pharmacists feel capable of performing this monitoring. The main barriers to overcome were the presence of only 1 pharmacist at work and limited time. Other factors identified offer complementary intervention targets.

Causes of drug discontinuation in patients with major depressive disorder in China

BACKGROUND

This research was designed to investigate patient-reported and doctor-reported reasons for the discontinuation of pharmacological treatment in Chinese patients with major depressive disorder (MDD), which was part of the National Survey on Symptomatology of Depression (NSSD) from 2014 to 2015.

METHODS

This cross-sectional study included 649 patients who had discontinued antidepressant medications and 711 patients who had remained on them, selected from a group of 3516 candidates who have had at least one depressive episode. Differences in the two groups' sociodemographic factors, clinical characteristics, medication use, and self-reported reasons for drug discontinuation were compared via Student's t-test or chi-square test. Logistic regression analysis was then used to determine the association of all non-subjective dichotomous and ordinal categorical variables, including the additional 63 items of our physician-evaluated symptomatic assessment, with drug compliance.

RESULTS

Compared to the spontaneous drug discontinuation (SDD) group, the drug adherence (DA) group had significantly lower rates of the following: family history of mental disease (9.0% vs 13.6%), highest level of education achieved being post-graduate or above (1.6% vs 4.7%), smoking (5.8% vs 9.7%), and other health problems (33.9% vs 42.4%) (p's < 0.05). On the other hand, first-episode depression (48.5% vs 21.9%) and taking of mood stabilizer(s) (8.3% vs 5.6%) were higher in the former group than in the latter (p's < 0.05). Logistic Regression Analysis showed that five symptoms, such as depressed mood, were correlated positively with SDD, while another six symptoms, such as psychomotor retardation, were correlated negatively with it. The receiver operating characteristic (ROC) curve of this model yielded an area under the curve (AUC) of 0.701 (95% CI, 0.673-0.729). Notably, there were three main reasons given by patients in the DA group as to why they discontinued their medication(s): (1) concern about long-term side effects (36.1%), (2) no perceived need for taking said medication(s) long-term (34.2%), and (3) believing oneself to have been cured completely (30.0%).

CONCLUSIONS

The aforementioned factors may affect patient compliance and elicit maladaptive thinking even from patients with good educational backgrounds, increasing the risk of drug discontinuation. Compliance of pharmacological treatment might be improved by increasing clarification and elucidation of different symptom clusters to the patient and combating the main reasons for drug discontinuation.

Discontinuation Rates of Antidepressant Use by Dutch Soldiers

INTRODUCTION

Soldiers have a higher risk for developing psychiatric disorders that require treatment; often with antidepressants. However, antidepressants as well as the psychiatric disorder, may influence military readiness in several ways. In the general population, early discontinuation of antidepressant treatment is often seen. It is yet unknown whether this occurs to a similar extent in soldiers. The objective of this study was to evaluate discontinuation of antidepressant use by Dutch soldiers in the first 12 months after start and determinants thereof.

MATERIALS AND METHODS

Data were obtained from the military pharmacy. All Dutch soldiers who started using an antidepressant between 2000 and 2014 were included. Kaplan-Meier curves were constructed to estimate the discontinuation rate over time and the influence of each determinant on discontinuation rate was estimated using Cox regression.

RESULTS

About 25.9% of de 2479 starters had discontinued their antidepressant use after 1 month; after 3 and 6 months this number increased to 52.7% and 70.3%, respectively. Early discontinuation was higher in soldiers who received their first prescription from a neurologist or rehabilitation specialist (HR 1.85, 95% CI 1.55-2.21, HR 2.66 95% CI 1.97-3.58) compared to soldiers with a first prescription from a general practitioner. In addition, early discontinuation was lower in soldiers who were prescribed serotonin reuptake inhibitors and other antidepressants (HR 0.57, 95% CI 0.51-0.60, HR 0.63, 95% CI 0.55-0.73) and in soldiers between 40 and 50 years of age (HR 0.79, 95% CI 0.70-0.89).

CONCLUSION

More than half of the soldiers discontinued their prescribed antidepressant within 3 months and after 6 months, only 30% were still on antidepressants.

The use of psychotropic medications and non-pharmacological approaches in everyday life: a qualitative study of the lived experience

Increased consumption of psychotropic drugs has been noted in Brazil and other Western countries in the last few decades for different reasons. The objective of this study was to understand the lived experience of individuals who used psychotropic drugs to cope with the problems faced in daily life. A qualitative study guided by hermeneutic phenomenology was carried out. In-depth interviews were conducted. The experience was grouped into two themes: experience of using psychotropic and the search for non-pharmacological approaches. Psychotropics were considered necessary for regaining a point of equilibrium when the problems faced were recognized as having a high degree of difficulty. In some cases, the drugs were perceived as insufficient for solving the problem, leading or not to the search for alternatives to deal with the difficulty.

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.

Experiences with the daily use of medications among chronic hepatitis C patients

BACKGROUND

Subjective experiences with medication use are individual experiences that can impact health outcomes by contributing to problems related to such use.

OBJETIVES

The aim of the present study was to understand the experiences of chronic hepatitis C patients who were taking chronic medications, based on the phenomenology proposed by Merleau-Ponty and connection among this experience with the essential structures of the experience.

METHODS

Data were gathered from interviews conducted with ten individuals taking long-term medications at the Viral Hepatitis Outpatient Clinic of the Alfa Gastroenterology Institute of the Hospital das Clínicas, Federal University of Minas Gerais, Brazil. The content of field diaries kept during the interviews were also used. Thematic analysis was employed, enabling the identification of the ways in which individuals experienced their medication routines, which were then reorganized to encompass the essential structures of the experience.

RESULTS

The researchers identified four ways patients experience daily medication use, all anchored in corporeality: resolution, adversity, ambiguity, and irrelevance. The first three were based on the perspective that daily medication use is more than a mere mechanical action, involving changes in the phenomenal body, relieving, eliminating or causing symptoms in the physical body, normalizing life and symbolizing the disease.

FINAL CONSIDERATIONS

The present study allowed the researchers to infer that the same individual can even simultaneously experience daily medication use in different ways, depending on the disease and the medication in question. It also allowed for the understanding of the cyclical nature of experience with daily medication use, being that the introduction of a new medication can give rise to a new experience. The results point to the complexity of this experience, which requires formal education and places health professionals as responsible for this aspect of care.

Non-adherence to antidepressants among older patients with depression: a longitudinal cohort study in primary care

BACKGROUND

Depression is common among older adults and is typically treated with antidepressants.

OBJECTIVE

To determine the non-adherence rates to antidepressants among older adults in primary care, based on non-initiation, suboptimal implementation or non-persistence.

METHODS

We selected all patients aged ≥60 years and diagnosed with depression in 2012, from the Netherlands Institute for Health Services Research (NIVEL) Primary Care Database. Non-initiation was defined as no dispensing within 14 days of the first prescription; suboptimal implementation, as fewer than 80% of the days covered by dispensed dosages; and non-persistence, as discontinuation within 294 days after first dispense. First, we determined the antidepressant non-initiation, suboptimal implementation and non-persistence rates. Second, we examined whether comorbidity and chronic drug use were associated with non-adherence by mixed-effects logistic regression (non-initiation or suboptimal implementation as dependent variables) and a clustered Cox regression (time to non-persistence).

RESULTS

Non-initiation, suboptimal implementation and non-persistence rates were 13.5%, 15.2% and 37.1%, respectively. As the number of chronically used drugs increased, the odds of suboptimal implementation (odds ratio, 0.89; 95% confidence interval, 0.83-0.95) and of non-persistence (hazard ratio, 0.87; 95% confidence interval, 0.82-0.92) reduced.

CONCLUSIONS

Non-adherence to antidepressants is high among older patients with depression in primary care settings. Adherence is better when patients are accustomed to taking larger numbers of prescribed drugs, but this only provides partial explanation of the variance. GPs should be aware of the high rates of non-adherence. Emphasizing the importance of adhering to the optimal length of antidepressant therapy might be prudent first steps to improving adherence.

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.

Women's decision making about antidepressant use during pregnancy: A narrative review

BACKGROUND

Depression is common, particularly among women of childbearing age, and can have far-reaching negative consequences if untreated. Efficacious treatments are available, but little is known about how women make depression treatment decisions during pregnancy. The purpose of this narrative review is to interpretively synthesize literature on women's decision making (DM) regarding antidepressant use during pregnancy.

METHODS

The databases PubMed, CINAHL, and PsycINFO were searched between May 2015 and August 2017 for peer-reviewed, English-language papers using terms such as "depression," "pregnancy," and "DM." The literature matrix abstraction method was used to systematically abstract data from full articles that met criteria for inclusion.

RESULTS

Of the articles abstracted (N = 10), half did not cite a DM theory on which the work was based. Key aspects of DM for this population were need for information and decision support, desire for active participation in DM, reflection on beliefs and values, evaluation of treatment option sequelae, and societal expectations. Treatment DM for depression during pregnancy is particularly impacted by the stigma associated with depression and societal expectations of pregnant women related to medication use during pregnancy. These findings, however, were based on studies of predominantly Caucasian and well-educated women.

CONCLUSIONS

Women require a nonjudgmental environment, in which shared DM feels safe, to foster positive DM experiences and outcomes. Future research is needed to define how to best support women to make depression treatment decisions in pregnancy, with particular attention to DM in the second and third trimesters of pregnancy.

Development of a Strategic Tool for Shared Decision-Making in the Use of Antidepressants among Patients with Major Depressive Disorder: A Focus Group Study

Shared decision-making (SDM) has been recognized as an important tool in the mental health field and considered as a crucial component of patient-centered care. Therefore, the purpose of this study was to develop a strategic tool towards the promotion and implementation of SDM in the use of antidepressants among patients with major depressive disorder. Nineteen doctors and 11 major depressive disorder patients who are involved in psychiatric outpatient clinic appointments were purposively selected and recruited to participate in one of six focus groups in a large teaching hospital in Malaysia. Focus groups were transcribed verbatim and analyzed using a thematic approach to identify current views on providing information needed for SDM practice towards its implementation in near future. Patients&rsquo; and doctors&rsquo; views were organized into six major themes, which are; summary of treatment options, correct ways of taking medication, potential side effects of treatments related to patients, sharing of case study related to the treatment options, cost of treatment options, and input from pharmacist. The information may be included in the SDM tool which can be useful to inform further research efforts and developments that contribute towards the successful implementation of SDM into clinical practice.

The Development of a Community Pharmacy-Based Intervention to Optimize Patients' Use of and Experience with Antidepressants: A Step-by-Step Demonstration of the Intervention Mapping Process

Objective: To describe the development of a community pharmacy-based intervention aimed at optimizing experience and use of antidepressants (ADs) for patients with mood and anxiety disorders. Methods: Intervention Mapping (IM) was used for conducting needs assessment, formulating intervention objectives, selecting change methods and practical applications, designing the intervention, and planning intervention implementation. IM is based on a qualitative participatory approach and each step of the intervention development process was conducted through consultations with a pharmacists' committee. Results: A needs assessment was informed by qualitative and quantitative studies conducted with leaders, pharmacists, and patients. Intervention objectives and change methods were selected to target factors influencing patients' experience with and use of ADs. The intervention includes four brief consultations between the pharmacist and the patient: (1) provision of information (first AD claim); (2) management of side effects (15 days after first claim); (3) monitoring treatment efficacy (30-day renewal); (4) assessment of treatment persistence (2-month renewal, repeated every 6 months). A detailed implementation plan was also developed. Conclusion: IM provided a systematic and rigorous approach to the development of an intervention directly tied to empirical data on patients' and pharmacists' experiences and recommendations. The thorough description of this intervention may facilitate the development of new pharmacy-based interventions or the adaptation of this intervention to other illnesses and settings.

Patient perspectives on the role of community pharmacists for antidepressant treatment: A qualitative study

Objectives

Patients prescribed antidepressant drug treatment (ADT) for major depression report several needs in relation to their treatment, and a large proportion of these patients will end ADT prematurely. Community pharmacists may play an important role in monitoring ADT and supporting these patients. However, little is known about patient experiences of the services provided in community pharmacies. The objectives of this study were to 1) explore patients' experiences with the services community pharmacists provide for ADT and 2) identify potential avenues for improvement of pharmacists' services within the context of ADT.

Methods

A qualitative descriptive exploratory study was conducted among individuals diagnosed with major depression who had initiated ADT at some point in the 12 months prior to their participation in the study. A total of 14 persons recruited in a local health centre and a community-based organization participated in individual interviews. A thematic analysis of the interview transcripts was conducted.

Results

Pharmacists tend to concentrate their involvement in treatment at initiation and at the first refill when questions, uncertainties and side effects are major issues. Patients felt that the pharmacists' contributions consisted of providing information and reassurance; in these respects, their needs were met. Participants had few ideas as to what additional services pharmacists could implement to improve patients' experience with ADT. Patients' sole expectations were that pharmacists extend this information role to the whole length of the treatment and enhance the confidentiality of discussions in pharmacy.

Conclusion

Pharmacists should provide counselling throughout the entire treatment rather than passively waiting for patients to ask their questions. However, facilitation of open discussions may not be achieved unless confidentiality at pharmacies is secured.

Consumer-related factors influencing antidepressant adherence in unipolar depression: a qualitative study

PURPOSE

To explore factors which facilitate and negatively impact adherence, at initiation, implementation and discontinuation phases of adherence to antidepressant medicines.

PATIENTS AND METHODS

Semi-structured, face-to-face interviews were conducted with patients suffering from unipolar depression. The digitally audio-recorded and transcribed verbatim were used. Transcripts were thematically content analyzed and data managed using N-Vivo software.

RESULTS

Twenty-three interviews were conducted. The predominant factors facilitating initiation of therapy included self-motivation and severity of depression. Factors aiding persistence with therapy included belief in, and effectiveness of, antidepressants. Stigma and fear of adverse events inhibited initiation of therapy, whilst adverse events and ineffectiveness of antidepressants contributed to discontinuation. Patients with strong perceptions of the necessity and few concerns about antidepressants were more likely to adhere to treatment at all phases of adherence.

CONCLUSION

Different factors influence medication adherence at the different phases of adherence. These factors were based on individual perceptions about depression and its treatment, and actual experiences of antidepressant treatment. This information should be considered by health care professionals in delivering targeted and tailored interventions to foster adherence. Strategies to address medication non-adherence in unipolar depression patients should consider the phase of adherence and individual perceptions about depression and its treatment, along with previous experiences with treatment for depression.

Guidance by physicians and pharmacists during antidepressant therapy: patients' needs and suggestions for improvement

BACKGROUND

Guidance of patients treated with antidepressants is paramount for successful therapy. The aim was to assess patients' needs and suggestions for improvement of guidance by physicians and pharmacists during second generation antidepressant (SGA) therapy.

METHODS

Five focus group discussions were held with a total of 34 patients using an SGA. The discussions were conducted flexibly and responsively using a semi-structured topic list. All focus group discussions were video-recorded and transcripts were analyzed using ATLAS.ti for coding, thematic and open analysis.

RESULTS

Participants stated they were in need of better guidance. They suggested improving content of information during decisional moments, patient-health care professional communication and communication between health care professionals, and finally, organization of guidance. Barriers to achieving improved guidance were cited.

CONCLUSIONS

Content, communication and organization of guidance are pivotal for achieving optimal guidance. Participants mentioned their current experienced guidance had limitations and brought up solutions for improvement. A next step would be to discuss the suggested solutions with health care professionals to assess their views and to discuss the possibility for implementation. After implementation, future studies could be aimed at determination of its impact on patients' treatment efficacy, quality of life, treatment satisfaction and healthcare costs.

Experiences of wake and light therapy in patients with depression: A qualitative study

Wake therapy can reduce depressive symptoms within days, and response rates are high. To sustain the effect, it is often combined with light therapy. Few studies have focussed on factors related to patients' adherence to the regime, and none has used qualitative methods to examine their experience of these combined interventions. Therefore, the aim of the present study was to illuminate patients' experiences with wake and light therapy and factors related to adherence. Thirteen inpatients with depression were included. They participated in an intervention consisting of three wake therapies during the first week, 30 min of daily light treatment for the entire 9 weeks, and ongoing psychoeducation regarding good sleep hygiene. Patients kept a diary, and individual semistructured interviews were conducted. Data were analysed using qualitative content analysis. The participants' overall experience with the treatment was positive. Some experienced a remarkable and rapid antidepressant effect, whereas others described more long-term benefits (e.g. improved sleep and diurnal rhythm). Yet recovery was fragile, and patients were only cautiously optimistic. Social support was important for maintaining the motivation to stay awake and receive daily light therapy. Overall, participants found the treatment worthwhile and would recommend it to others with depression. The study revealed a lack of knowledge among participants about the connection between regular sleep patterns and depression. In conclusion, this study provides insight into patients' experiences, and knowledge that can contribute to guidelines for future adherence-promoting organization of wake and light therapy.

Long-term antidepressant use: a qualitative study on perspectives of patients and GPs in primary care

BACKGROUND

Antidepressant use is often prolonged in patients with anxiety and/or depressive disorder(s) compared with recommendations in treatment guidelines to discontinue after sustained remission.

AIM

To unravel the motivations of patients and GPs causing long-term antidepressant use and to gain insight into possibilities to prevent unnecessary long-term use.

DESIGN AND SETTING

Qualitative study using semi-structured, in-depth interviews with patients and GPs in the Netherlands.

METHOD

Patients with anxiety and/or depressive disorder(s) (n = 38) and GPs (n = 26) were interviewed. Innovatively, the interplay between patients and their GPs was also investigated by means of patient-GP dyads (n = 20).

RESULTS

The motives and barriers of patients and GPs to continue or discontinue antidepressants were related to the availability of supportive guidance during discontinuation, the personal circumstances of the patient, and considerations of the patient or GP. Importantly, dyads indicated a large variation in policies of general practices around long-term use and continuation or discontinuation of antidepressants. Dyads further indicated that patients and GPs seemed unaware of each other's (mismatching) expectations regarding responsibility to initiate discussing continuation or discontinuation.

CONCLUSION

Although motives and barriers to antidepressant continuation or discontinuation were related to the same themes for patients and GPs, dyads indicated discrepancies between them. Discussion between patients and GPs about antidepressant use and continuation or discontinuation may help clarify mutual expectations and opinions. Agreements between a patient and their GP can be included in a patient-tailored treatment plan.

ANTIDEPRESSANT ADHERENCE ACROSS DIVERSE POPULATIONS AND HEALTHCARE SETTINGS

BACKGROUND

Early adherence is key to successful depression treatment, but nearly 60% of patients discontinue antidepressants within 3 months. Our study aimed to determine factors associated with poor early adherence to antidepressants in a large diverse sample of patients.

METHODS

Six Mental Health Research Network healthcare systems contributed data for adults with depression and a new antidepressant start, defined by a washout period of at least 270 days, between January 1, 2010 and December 31, 2012. Pharmacy fill and self-reported race/ethnicity data were obtained from the electronic medical record. Patients had early adherence if they had a second antidepressant fill within 180 days of the first. We used logistic regression to investigate the relationship between early adherence and patient characteristics.

RESULTS

A total of 177,469 adult patients had 184,967 new episodes of depression with a filled antidepressant prescription. Patients refilled their antidepressants within 180 days in 71% of episodes. Race/ethnicity was a strong predictor of early adherence, with patients from racial/ethnic minorities other than Native Americans/Alaskan Natives less likely (adjusted odd ratios 0.50-0.59) to refill their antidepressants than non-Hispanic whites. Age, neighborhood education, comorbidity burden, provider type and engagement in psychotherapy were also associated with adherence. Other apparent predictors of early adherence, including neighborhood income, gender, and prior mental health hospitalizations, were no longer significant in the fully adjusted model.

CONCLUSIONS

Race/ethnicity was a robust predictor of early antidepressant adherence, with minority groups other than Native Americans/Alaskan Natives less likely to be adherent. Further research is needed to determine whether early nonadherence in specific minority populations is intentional, due to side effects or patient preference, or unintentional and appropriate for targeted interventions to improve adherence.

The effect of knowledge and expectations on adherence to and persistence with antidepressants

PURPOSE

Adherence to and persistence with antidepressants are often suboptimal. However, little is known about how patient knowledge and outcome expectations may influence antidepressant adherence and persistence.

METHOD

Individuals who had been prescribed their first antidepressant to treat depression in the preceding 6 months were recruited to an online survey via Facebook. Knowledge, education received, and initial outcome expectations were analyzed for associations with persistence and adherence.

RESULTS

Two hundred and twenty surveys were analyzed. A total of 117 participants had taken their antidepressant for at least 3 months; another 25 had never started or stopped after <3 months without consulting their doctor. Differences in expectations and various educational messages among persistent and nonpersistent participants were identified. Having received the instruction "don't stop it without checking with your doctor" was a significant independent predictor of persistence (odds ratio [OR] =5.9, 95% confidence interval [CI] =1.4-24.5). At the time of the survey, 82.7% of participants were taking an antidepressant and 77.9% were adherent. Significant independent predictors of adherence were a greater age (OR =1.1, 95% CI =1.0-1.2), knowledge (OR =1.6, 95% CI =1.1-2.3), being informed of common side effects (OR =5.5, 95% CI =1.1-29.0), and having discussed ways to solve problems (OR =3.9, 95% CI =1.1-14.5).

CONCLUSION

Improving outcome expectations and particular educational messages may increase adherence and persistence. Greater knowledge may enhance adherence. Further investigation is warranted to determine whether a focus on these simple educational messages will improve outcomes in patients who commence an antidepressant.

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.

Restarting antidepressant treatment following early discontinuation--a primary care database study

BACKGROUND

Many patients in primary care stop antidepressant treatment after only one prescription, so do not benefit from treatment. Some patients who stop initial antidepressant treatment go on to restart it, but neither the incidence of restarting nor the probability that patients who restart treatment subsequently complete an adequate course of treatment is known.

OBJECTIVE

To examine subsequent antidepressant use in patients who discontinued treatment after only one antidepressant prescription.

METHODS

We used a primary care database (over 1.2 million records) to study patients who commenced treatment with an eligible antidepressant between April 2007 and March 2008 and who stopped treatment for at least 1 month after the first prescription. We examined their subsequent antidepressant prescriptions to estimate the probability of restarting antidepressant treatment, the likelihood of continuing subsequent treatment and the patient characteristics associated with these.

RESULTS

Out of 24817 patients, 6952 (28%) patients discontinued antidepressant treatment after the first prescription. The cumulative probability of restarting treatment after early discontinuation was 8.6% (95% confidence interval [CI] 8.0-9.3) after 1 month off-treatment, and 24.1% (22.9-25.2) after 9 months off-treatment. The probability of those who restarted treatment continuing for 6 months or more was 29.3% (26.5-32.5).

CONCLUSIONS

Few patients who stop antidepressant treatment after the first prescription subsequently complete an adequate treatment course within the next year. Initiatives to promote adherence to appropriate antidepressant treatment should begin during the first prescription.

Adherence to anti-depressant medication: a medicine-taking career

The study of medicine taking is controversial as it often reveals a discrepancy between healthcare professionals' advice and patients' actual behaviour. Qualitative researchers have examined depressed people's adherence to prescriptions of antidepressants by exploring the meaning they impute to the medicine and their use of the medicine in the wider context of their everyday lives. This paper contributes to this area of research by means of a prospective research study focussing on depressed patients' perspectives on taking medicine and how they change through time. The study included consecutive semi-structured interviews with 16 people four times during the year following an admission to hospital for depression. Data were collected in 2008-2009 in the Region of Southern Denmark. The study was based on an interactionist conception of social career and data were analysed thematically. Findings indicated that participants were confronted with recurrent challenges related to being depressed and taking medicine, and they learned how to manage these challenges in a post-admission career with two distinct stages: the basic restitution stage and the frustrated search stage. Medicine-taking depended on a number of career moving tensions and problems. The basic restitution stage was characterised by the participants' readiness to take medicine in accordance with healthcare professionals' prescriptions and advice. Half of the participants experienced being challenged by unacceptable prolonged mental, social, and/or physical distress, and they moved to the frustrated search stage, which was characterised by an alternative perspective on taking medicine that included increased self-regulation and less involvement of healthcare professionals and next of kin. Healthcare professionals played a very peripheral role in most participants' lives and unsatisfactory interactions often isolated participants and left them to solve their own problems.

Knowledge, attitudes and beliefs of patients and carers regarding medication adherence: a review of qualitative literature

PURPOSE

The aim of this review is to cohere evidence on the knowledge, attitudes and beliefs of patients and carers regarding medication adherence. Medication adherence refers to "the extent to which the patient's action matches the agreed recommendations". Medication adherence is vital in preventing, managing and curing illnesses and, hence, is linked with positive health outcomes.

METHODS

A search was conducted using the following databases: CINAHL, Embase, PubMed and Web of Knowledge from inception to November 2013. Titles and abstracts were screened for inclusion in the review according to pre-defined inclusion and exclusion criteria. Studies were assessed for quality, and data were extracted into a data extraction form. Results were analysed thematically.

RESULTS

The final results included 34 articles. Eight analytical themes were identified: (i) beliefs and experiences of medicines, (ii) family support and culture, (iii) role of and relationship with health-care practitioners, (iv) factors related to the disease, (v) self-regulation, (vi) communication, (vii) cost and (viii) access. The theme, "beliefs and experiences of medicines", was present in 33 studies, with many discussing the influence that side effects have on medication adherence.

CONCLUSIONS

There are a number of variables that impact upon the knowledge, attitudes and beliefs of patients and carers regarding medication adherence. This review presents an overview of the analytical themes which offers the opportunity to examine interventions and their relative efficacies to increase medication adherence.

Factors predicting adherence to antidepressant treatment

PURPOSE OF REVIEW

Poor adherence and discontinuation of treatment are the major challenges of pharmacotherapy among patients with depression. This article reviews the factors predicting adherence to and persistence of antidepressant treatment identified in recent years.

RECENT FINDINGS

Study populations have been extended to subgroups of patients with depression or depressive patients with comorbid medical conditions. Some studies have investigated the issues by analysing medical claims databases. Socio-demographic variables, clinical features of depression, comorbidities, pharmacological factors, attitudes towards antidepressants, previous experiences of antidepressant treatment, patient-professional relationship and genes were found to be common factors. An older age, positive attitudes to antidepressants and previous experiences and vicarious experiences of depression or treatment were found to be factors predicting better adherence or persistence. Conversely, patients in minority groups, those with a low family income, pregnancy, experience of side effects, dissatisfaction with treatment and a poor patient-professional relationship were found to be associated with poorer adherence or persistence.

SUMMARY

The factors predicting adherence and persistence are complex and interactive. Different methods of studies have limitations in terms of exploring all these factors. Future studies should integrate these factors simultaneously and explore specific factors predicting adherence and persistence among subgroups of patients with depression.

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.

Pharmacist-patient communication on use of antidepressants: a simulated patient study in community pharmacy

BACKGROUND

Effective communication between community pharmacists and patients, particularly with a patient-centered approach, is important to address patients' concerns relating to antidepressant medication use. However, few studies have investigated community pharmacists' communication behaviors in depression care.

OBJECTIVE

To characterize community pharmacist-patient interactions during consultations involving use of antidepressants.

METHODS

Twenty community pharmacists received 3 simulated patient visits involving issues related to the use of antidepressants: 1) patient receiving a first-time antidepressant prescription; 2) patient perceiving lack of efficacy of antidepressants after 2 weeks of treatment, and 3) patient intending to discontinue treatment prematurely. All 60 encounters were audio-recorded and analyzed using the Roter Interaction Analysis System (RIAS), a quantitative coding system that characterizes communication behaviors through discrete categories. A patient-centeredness score was calculated for each encounter.

RESULTS

The majority of pharmacist communication was biomedical in nature (50.7%), and focused on providing therapeutic information and advice on the antidepressant regimen. In contrast, only 5.4% of pharmacist communication was related to lifestyle/psychosocial exchanges. There were also few instances of emotional rapport-building behaviors (8.6%) or information gathering (6.6%). Patient-centered scores were highest in the scenario involving a first-time antidepressant user, as compared to other scenarios involving issues with continued therapy.

CONCLUSIONS

Community pharmacists appeared to adopt a "medication-centered" approach when counseling on antidepressant issues. There is scope for improvement in patient-centered communication behaviors, particularly lifestyle/psychosocial discussions, facilitating patient participation, and emotional rapport-building. The RIAS appears suited to characterize brief consultations in community pharmacies and can provide a framework in guiding communication training efforts. Further research is needed to assess the impact of pharmacist communication behaviors on patient care outcomes.

Patient experiences of taking antidepressants for depression: a secondary qualitative analysis

BACKGROUND

Depression is one of the most commonly encountered mental health problems leading to significant morbidity and mortality and high medical and societal costs. Antidepressant prescribing in the UK has more than doubled in the last decade. There are a variety of factors that have been shown to affect a patient's experience of taking antidepressants The aim of this research was to explore patient narratives interviews about depression and its treatment in order to improve patient and health professional understanding of what it is like to use antidepressants.

METHODS

This study involved a supplementary secondary qualitative analysis of 80 in-depth narrative interviews from Healthtalkonline. Patients' experiences of using medicines for depression were explored in the context of their social, occupational and emotional impact, to identify any additional issues and to clarify what type of information people want to find after being prescribed a medicine. The interviews were conducted by the University of Oxford and had received ethical approval and been consented and copyrighted for this purpose. Data were analyzed thematically.

RESULTS

The most prominent theme was the coexistence of several conflicting issues around the use of medicines and participants were mostly influenced by the reality of their experiences, beliefs, attitudes and interaction with health care. Antidepressants appear to occupy a central place in many people' lives. Many people described how their medicines had helped them and how this served as a reinforcement to continue taking them in order to maintain a "normal life." Those who had stopped taking their antidepressants were likely to have experienced adverse reactions and had unsatisfactory interactions with health care professionals. A lack of information about antidepressants was a major cause of dissatisfaction often shaping attitudes to antidepressants'.

CONCLUSIONS

People's experiences with antidepressant use have a major impact on treatment continuation and hence treatment outcomes. Further studies are needed on depressed patients' beliefs about their depression and treatment and how they relate to different stages of illness, their interactions with health care and their adherence to antidepressants.

Duration and compliance with antidepressant treatment in immigrant and native-born populations in Spain: a four year follow-up descriptive study

Background

Non-compliance with antidepressant treatment continues to be a complex problem in mental health care. In immigrant populations non-compliance is one of several barriers to adequate management of mental illness; some data suggest greater difficulties in adhering to pharmacological treatment in these groups and an increased risk of therapeutic failure.

The aim of this study is to assess differences in the duration and compliance with antidepressant treatment among immigrants and natives in a Spanish health region.

Methods

Population-based (n=206,603), retrospective cohort study including all subjects prescribed ADT between 2007 and 2009 and recorded in the national pharmacy claims database. Compliance was considered adequate when the duration was longer than 4months and when patients withdrew more than 80% of the packs required.

Results

5334 subjects (8.5% of them being immigrants) initiated ADT. Half of the immigrants abandoned treatment during the second month (median for natives=3months). Of the immigrants who continued, only 29.5% presented good compliance (compared with 38.8% in natives). The estimated risk of abandoning/ending treatment in the immigrant group compared with the native group, adjusted for age and sex, was 1.28 (95%CI 1.16-1.42).

Conclusions

In the region under study, immigrants of all origins present higher percentages of early discontinuation of ADT and lower median treatment durations than the native population. Although this is a complex, multifactor situation, the finding of differences between natives and immigrants in the same region suggests the need to investigate the causes in greater depth and to introduce new strategies and interventions in this population group.

Patients' satisfaction with information and experiences with counseling on cardiovascular medication received at the pharmacy

OBJECTIVE

To assess the extent to which patients feel they have received enough information on cardiovascular drugs and experienced counseling at the pharmacy. In addition, to identify factors that are predictors for patient satisfaction with the information received.

METHODS

Fifteen community pharmacies participated. New and chronic users of cardiovascular medication received a questionnaire containing sociodemographic and health questions, a measure of satisfaction with information received (SIMS), beliefs about medication (BMQ), and frequency of pharmacy counseling.

RESULTS

Of the 578 respondents, 335 (58%) indicated to be unsatisfied with the information received on 3 or more SIMS items. Patients' age, beliefs about medication, duration of cardiovascular treatment and use of antithrombotics predicted patients' satisfaction with information received. Two-thirds of patients reported 'never' to have experienced 5 of 8 counseling activities at the pharmacy.

CONCLUSIONS

A considerable proportion of patients are unsatisfied with the information received on cardiovascular medication. The majority of patients have only received a limited scope of medication counseling at the pharmacy.

PRACTICE IMPLICATIONS

Information and counseling should be tailored to patients' needs and concerns about cardiovascular medication and the experience patients already have with treatment. Pharmacists could enhance their role in supporting patients using cardiovascular medication.
