Pharmacy-based management for depression in adults

The evolving role of pharmacists in depression care: a scoping review

BACKGROUND

Worldwide, depression is known to contribute significantly to the global burden of disease. Considering pharmacists are among the most approachable healthcare providers, they are well-placed to assist people with depression achieve positive treatment outcomes.

AIM

The primary aim was to examine the evidence regarding pharmacists' roles in interventions, outcomes, and barriers to implementation within depression care globally, with the secondary aim focusing on the Arab region.

METHOD

A scoping review was conducted according to the PRISMA-ScR extension guidelines and the Joanna Briggs Institute framework, using Scopus, Cochrane, ProQuest, and Medline databases for studies worldwide and within the Arab region (22 Arab-league countries). Article selection, along with data extraction, analysis, and narrative synthesis were performed independently by two reviewers. Discrepancies were resolved by consensus.

RESULTS

Forty studies reporting various roles and services provided by pharmacists in depression management were included. Most articles (24) described studies on pharmacist-led specific/single interventions/management strategies, and 16 described studies in which pharmacists provided comprehensive or team-based services. The majority of studies reported positive impact on patient outcomes. In accordance with the secondary aim, only three studies assessed various pharmacists' services for people with depression in the Arab region. Barriers to effective depression-related care included time constraints and training needs.

CONCLUSION

This scoping review supports the expanding role of pharmacists in depression management. The interventions, impact, challenges, and research gaps identified serve as preliminary evidence for advocating for an expanded pharmacists' scope of practice in mental health, both globally and in the Arab region.

Interventions to Expand Community Pharmacists' Scope of Practice

BACKGROUND

The role of community pharmacists has evolved beyond the dispensing of medicines. The aim of this scoping review was to describe the interventions that expand the pharmacist's scope of practice within a community pharmacy setting and assess their effectiveness.

METHODS

We performed a scoping review to identify randomised controlled trials (RCTs), published worldwide from 2013 to 2024, which focused on interventions designed to expand pharmacists' scope of practice in the community. The review was undertaken in accordance with the Joanna Briggs Institute methodology for scoping reviews. To address the aim of this scoping review, the included RCTs were mapped to themes influenced by the Professional Practice Standards 2023 as developed by the Pharmaceutical Society of Australia: medication management, collaborative care and medication adherence.

RESULTS

Twelve studies demonstrated the potential to expand community pharmacists' scope of practice. Two RCTs resulted in no effect of the intervention. One RCT (conducted in Italy) led to an actual change to community pharmacists' scope of practice, with a statistically significant improvement in the proportion of patients with controlled asthma.

CONCLUSIONS

On the whole, this scoping review synthesised the findings of peer-reviewed RCT studies that revealed expanding community pharmacists' scope of practice may result in improved patient outcomes, a reduced burden for the healthcare system, and greater productivity.

Gaps in pharmaceutical care for patients with mental health issues: A cross-sectional study

Background

Mental health issues such as depression and anxiety are often underdiagnosed and undertreated. Medications are a primary method of managing mental health problems, and pharmacists therefore have a vital role in supporting patients and providing them with information about the safety and efficacy of mental health medications. However, the potential role of pharmacists in managing mental health issues in Jordan has not been well established.

Aim

This study aimed to assess Jordanian pharmacists’ attitudes and actual practices related to the provision of mental health services.

Method

This was an exploratory cross-sectional study that used a self-report questionnaire among a convenience sample of 347 pharmacists in Amman, the capital of Jordan.

Results

The participating pharmacists had positive attitudes towards providing care for patients with mental health problems. However, their actual practices did not resonate with their enthusiasm, particularly in terms of the long-term follow-up of disease symptoms and medication side effects and adherence. The participating pharmacists showed an eagerness to collaborate with their colleagues, but their level of actual cooperation was lower than desired. The most reported barrier to providing care for patients with mental health problems was the lack of education on mental health issues (71.5%), followed by the lack of privacy in pharmacy settings (53.9%).

Conclusion

To be effectively involved in the provision of care to mental health patients, pharmacists should receive adequate education/training related to mental health issues, and pharmacies should be redesigned to provide private areas for patient counseling.

A psychological intervention by community pharmacies to prevent depression in adults with subthreshold depression and long-term conditions: the CHEMIST pilot RCT

Background

Depression is common in people with long-term health conditions, and this combination can lead to worsened health outcomes and increased health-care costs. Subthreshold depression, a risk factor for major depression, is prevalent in this population, but many people remain untreated due to the demand on services. The community pharmacy may be an alternative setting to offer mental health support; however, insufficient evidence exists to support implementation.

Objectives

To conduct a feasibility study and pilot randomised controlled trial of a community pharmacy-delivered psychological intervention aimed at preventing depression in adults with long-term health conditions.

Design

A feasibility study with nested qualitative evaluation and an external pilot, two-arm, 1 : 1 individually randomised controlled trial with nested process and economic evaluations.

Setting

Community pharmacies in the north of England.

Participants

Adults aged ≥ 18 years with subthreshold depression and at least one long-term health condition.

Intervention

A bespoke enhanced support intervention (behavioural activation within a collaborative care framework) involving up to six sessions delivered by trained community pharmacy staff (intervention facilitators) compared with usual care.

Main outcome measures

Recruitment and retention rates, completeness of outcome measures and intervention engagement. The intended primary outcome was depression severity at 4 months, assessed by the Patient Health Questionnaire-9.

Results

In the feasibility study, 24 participants were recruited. Outcome measure completeness was 95–100%. Retention at 4 months was 83%. Seventeen participants (71%) commenced intervention sessions and all completed two or more sessions. Depression symptoms reduced slightly at 4 months. The process evaluation suggested that the intervention was acceptable to participants and intervention facilitators. In the pilot randomised controlled trial, 44 participants (target of 100 participants) were randomised (intervention, n = 24; usual care, n = 20). Outcome measure completeness was 100%. Retention at 4 months was 93%. Eighteen participants (75%) commenced intervention sessions and 16 completed two or more sessions. Depression symptoms reduced slightly at 4 months, with a slightly larger reduction in the usual-care arm, although the small sample size limits any conclusions. The process evaluation reported good acceptability of the intervention and identified barriers associated with study implementation and its impact on core pharmacy functions. The economic analysis revealed some indication of reduced resource use/costs associated with the intervention, but this is limited by the small sample size. Intervention costs were low.

Limitations

The main limitation is the small sample size due to difficulties with recruitment and barriers to implementing the study within existing pharmacy practices.

Conclusions

The community pharmacy represents a new setting to deliver a depression prevention intervention. Recruitment was a challenge and pharmacy staff encountered barriers to effective implementation of the study within busy pharmacy practice. Despite these challenges, good retention rates and intervention engagement were demonstrated, and process evaluation suggested that the intervention was acceptable in this setting. To the best of our knowledge, this is the first study to demonstrate that community pharmacy staff can be trained to deliver a depression prevention intervention.

Future work

Further work is needed to address barriers to recruitment, intervention delivery and implementation of psychological interventions in the community pharmacy setting.

Trial registration

This trial is registered as ISRCTN11290592.

The role of community pharmacists in depression management: a survey of attitudes, practices and perceived barriers

Background Community pharmacists play a significant role in depression care. Depression is a health priority in national health strategies around the world, including in Qatar. Objective To describe current practices, attitudes and perceived barriers of community pharmacists towards depression care, and to investigate factors associated with these practices. Setting Community pharmacies in Qatar. Method A cross-sectional online survey using an adapted survey instrument. Scores were measured on a five-point Likert scale. Descriptive univariate and bivariate analyses of study outcomes, followed by multivariate regression examining the association between pharmacists' practices and their attitudes, socio-demographic and professional characteristics. Main outcome measure Pharmacists' scores on self-reported attitudes towards depression and depression care practices and the number of perceived barriers for depression care. Result: 358 pharmacists (response rate 39%) completed the questionnaire. Pharmacists' attitudes to depression were moderately positive (mean score = 3.41, SD = 0.26) but involvement in depression care was very low (mean score = 2.64, SD = 0.94). Three major barriers were lack of access to patients' medical records (83.21%), lack of patients' insight on depression and the importance of treatment (81.85%), and lack of knowledge and training on mental health (79.63%). Female pharmacists and those graduated more than 10 years prior were significantly less involved in depression care compared to their counterparts (practice scores (95% CI) -4.36 (-7.46 to -1.26) and -7.51 (-15.10 to -1.35), respectively), while those who had access to private counselling area were more involved (practice score 3.39 (0.20 to 6.59). Pharmacists' depression practice score was positively associated with attitudes (p = 0.001). Conclusion Pharmacists' moderately positive attitudes were not reflected in their suboptimal depression-care practices. Action from policymakers is needed to improve pharmacists' practices and attitudes to depression.

Delivery of Pharmacogenetic Testing with or without Medication Therapy Management in a Community Pharmacy Setting

Objective

The delivery of pharmacogenetic (PGx) testing has primarily been through clinical and hospital settings. We conducted a study to explore the feasibility of delivering PGx testing through community pharmacies, a less-studied setting.

Methods

We conducted a cluster randomized trial of community pharmacies in North Carolina through two approaches: the provision of PGx testing alone or PGx testing with medication therapy management (MTM).

Results

A total of 150 patient participants were enrolled at 17 pharmacies and reported high satisfaction with their testing experience. Participants in the PGx plus MTM arm were more likely to recall a higher number of results (p=0.04) and more likely to clearly understand their choices for prevention or early detection of side effects (p=0.01). A medication or dose change based on the PGx results was made for 8.7% of participants.

Conclusion

Limited differences were observed in the provision of PGx testing as a standalone test or combined with MTM. A limited number of treatment changes were made based on PGx test results. Patient acceptance of PGx testing offered through the community pharmacy was very high, but the addition of MTM did not impact patient-reported perceptions about PGx testing or medication adherence.

Prognostic models for predicting relapse or recurrence of major depressive disorder in adults

BACKGROUND

Relapse (the re-emergence of depressive symptoms after some level of improvement but preceding recovery) and recurrence (onset of a new depressive episode after recovery) are common in depression, lead to worse outcomes and quality of life for patients and exert a high economic cost on society. Outcomes can be predicted by using multivariable prognostic models, which use information about several predictors to produce an individualised risk estimate. The ability to accurately predict relapse or recurrence while patients are well (in remission) would allow the identification of high-risk individuals and may improve overall treatment outcomes for patients by enabling more efficient allocation of interventions to prevent relapse and recurrence.

OBJECTIVES

To summarise the predictive performance of prognostic models developed to predict the risk of relapse, recurrence, sustained remission or recovery in adults with major depressive disorder who meet criteria for remission or recovery.

SEARCH METHODS

We searched the Cochrane Library (current issue); Ovid MEDLINE (1946 onwards); Ovid Embase (1980 onwards); Ovid PsycINFO (1806 onwards); and Web of Science (1900 onwards) up to May 2020. We also searched sources of grey literature, screened the reference lists of included studies and performed a forward citation search. There were no restrictions applied to the searches by date, language or publication status .

SELECTION CRITERIA

We included development and external validation (testing model performance in data separate from the development data) studies of any multivariable prognostic models (including two or more predictors) to predict relapse, recurrence, sustained remission, or recovery in adults (aged 18 years and over) with remitted depression, in any clinical setting. We included all study designs and accepted all definitions of relapse, recurrence and other related outcomes. We did not specify a comparator prognostic model.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened references; extracted data (using a template based on the CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS)); and assessed risks of bias of included studies (using the Prediction model Risk Of Bias ASsessment Tool (PROBAST)). We referred any disagreements to a third independent review author. Where we found sufficient (10 or more) external validation studies of an individual model, we planned to perform a meta-analysis of its predictive performance, specifically with respect to its calibration (how well the predicted probabilities match the observed proportions of individuals that experience the outcome) and discrimination (the ability of the model to differentiate between those with and without the outcome). Recommendations could not be qualified using the GRADE system, as guidance is not yet available for prognostic model reviews.

MAIN RESULTS

We identified 11 eligible prognostic model studies (10 unique prognostic models). Seven were model development studies; three were model development and external validation studies; and one was an external validation-only study. Multiple estimates of performance measures were not available for any of the models and, meta-analysis was therefore not possible. Ten out of the 11 included studies were assessed as being at high overall risk of bias. Common weaknesses included insufficient sample size, inappropriate handling of missing data and lack of information about discrimination and calibration. One paper (Klein 2018) was at low overall risk of bias and presented a prognostic model including the following predictors: number of previous depressive episodes, residual depressive symptoms and severity of the last depressive episode. The external predictive performance of this model was poor (C-statistic 0.59; calibration slope 0.56; confidence intervals not reported). None of the identified studies examined the clinical utility (net benefit) of the developed model.

AUTHORS' CONCLUSIONS

Of the 10 prognostic models identified (across 11 studies), only four underwent external validation. Most of the studies (n = 10) were assessed as being at high overall risk of bias, and the one study that was at low risk of bias presented a model with poor predictive performance. There is a need for improved prognostic research in this clinical area, with future studies conforming to current best practice recommendations for prognostic model development/validation and reporting findings in line with the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) statement.

Lived Experiences of a Sustained Mental Health Recovery Process Without Ongoing Medication Use

Serious mental health conditions have historically been considered lifelong conditions, with substantial literature supporting pharmaceutical approaches to remission. More recently, the recovery movement has emphasized lasting recovery, which can occur through a variety of pathways. With the traditional focus on medication, less is known about the recovery process of persons who achieve sustained recovery without ongoing medication use. This qualitative study used a grounded theory approach to explore the recovery process of 19 participants with diagnoses of schizophrenia, bipolar disorder, or major depression who were in recovery and not taking medications for at least twelve months. Participants identified internal recovery processes (cognitive changes, emotional processes, and spirituality/faith) leading to a perspective change about self and symptoms. Participants also identified external recovery processes including both support received and productive ways of giving back. The study findings highlight the importance of self-efficacy, emotion management, and social giving in mental health recovery.

Antidepressant treatment for postnatal depression

BACKGROUND

Depression is one of the most common morbidities of the postnatal period. It has been associated with adverse outcomes for women, children, the wider family and society as a whole. Treatment is with psychosocial interventions or antidepressant medication, or both. The aim of this review is to evaluate the effectiveness of different antidepressants and to compare their effectiveness with placebo, treatment as usual or other forms of treatment. This is an update of a review last published in 2014.

OBJECTIVES

To assess the effectiveness and safety of antidepressant drugs in comparison with any other treatment (psychological, psychosocial, or pharmacological), placebo, or treatment as usual for postnatal depression.

SEARCH METHODS

We searched Cochrane Common Mental Disorders's Specialized Register, CENTRAL, MEDLINE, Embase and PsycINFO in May 2020. We also searched international trials registries and contacted experts in the field.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of women with depression during the first 12 months postpartum that compared antidepressant treatment (alone or in combination with another treatment) with any other treatment, placebo or treatment as usual.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from the study reports. We requested missing information from study authors wherever possible. We sought data to allow an intention-to-treat analysis. Where we identified sufficient comparable studies we pooled data and conducted random-effects meta-analyses.

MAIN RESULTS

We identified 11 RCTs (1016 women), the majority of which were from English-speaking, high-income countries; two were from middle-income countries. Women were recruited from a mix of community-based, primary care, maternity and outpatient settings. Most studies used selective serotonin reuptake inhibitors (SSRIs), with treatment duration ranging from 4 to 12 weeks. Meta-analysis showed that there may be a benefit of SSRIs over placebo in response (55% versus 43%; pooled risk ratio (RR) 1.27, 95% confidence interval (CI) 0.97 to 1.66); remission (42% versus 27%; RR 1.54, 95% CI 0.99 to 2.41); and reduced depressive symptoms (standardised mean difference (SMD) -0.30, 95% CI -0.55 to -0.05; 4 studies, 251 women), at 5 to 12 weeks' follow-up. We were unable to conduct meta-analysis for adverse events due to variation in the reporting of this between studies. There was no evidence of a difference between acceptability of SSRI and placebo (27% versus 27%; RR 1.10, 95% CI 0.74 to 1.64; 4 studies; 233 women). The certainty of all the evidence for SSRIs was low or very low due to the small number of included studies and a number of potential sources of bias, including high rates of attrition. There was insufficient evidence to assess the efficacy of SSRIs compared with other classes of antidepressants and of antidepressants compared with other pharmacological interventions, complementary medicines, psychological and psychosocial interventions or treatment as usual. A substantial proportion of women experienced adverse effects but there was no evidence of differences in the number of adverse effects between treatment groups in any of the studies. Data on effects on children, including breastfed infants, parenting, and the wider family were limited, although no adverse effects were noted.

AUTHORS' CONCLUSIONS

There remains limited evidence regarding the effectiveness and safety of antidepressants in the management of postnatal depression, particularly for those with more severe depression. We found low-certainty evidence that SSRI antidepressants may be more effective in treating postnatal depression than placebo as measured by response and remission rates. However, the low certainty of the evidence suggests that further research is very likely to have an important impact on our effect estimate. There is a continued imperative to better understand whether, and for whom, antidepressants or other treatments are more effective for postnatal depression, and whether some antidepressants are more effective or better tolerated than others. In clinical practice, the findings of this review need to be contextualised by the extensive broader literature on antidepressants in the general population and perinatal clinical guidance, to inform an individualised risk-benefit clinical decision. Future RCTs should focus on larger samples, longer follow-up, comparisons with alternative treatment modalities and inclusion of child and parenting outcomes.

S116: Impact of incisional negative pressure wound therapy on surgical site infection after complex incisional hernia repair: a retrospective matched cohort study

INTRODUCTION

Incisional negative pressure wound therapy (iNPWT) may reduce surgical site infections (SSI), which can have devastating consequences after incisional hernia repair. Few comparative studies investigate the effectiveness of this wound management strategy in this population. The objective of this study is to determine the effect of iNPWT on the incidence of SSI after complex incisional hernia repair.

METHODS

All adult patients undergoing open incisional hernia repair at a single center from 2016 to 2019 were reviewed. A commercial iNPWT dressing was used at the discretion of the surgeon. Patients were grouped by type of dressing; iNPWT and standard sterile dressings (SSD). Coarsened exact matching was used to create balanced cohorts for comparison using age, sex, American Society of Anesthesiologists classification, wound classification, and surgical urgency. The primary outcome was the composite incidence of superficial and deep SSI within 30 days. Secondary outcomes included non-infectious surgical site occurrences (SSO), overall complications, length of stay (LOS), emergency department visits, and readmission at 30 days.

RESULTS

134 patients underwent complex hernia repair, with 114 patients included after matching (34 iNPWT, 51 SSD). Composite incidence of superficial and deep SSI was 19.3% (11.8% vs. 27.5%, p = 0.107), with significantly lower rates of deep SSI in patients receiving iNPWT (2.9% vs. 17.6%, p = 0.045). After accounting for residual differences between groups, iNPWT was associated with decreased incidence of composite SSI (RR 0.36, 95% CI [0.16, 0.87]). Median LOS was longer in patients with iNPWT (7 vs. 5 days, p = 0.001). There were no differences in SSO, overall complications, readmission, or emergency department visits.

CONCLUSION

In patients undergoing incisional hernia repair, the use of iNPWT was associated with a lower incidence of SSI at 30 days. Future studies should focus on cost effectiveness of iNPWT, its impact on long-term hernia recurrences, and the identification of patient selection criteria in this population.
