Creation and validation of a semi-quantitative instrument to assess the confidence of pharmacists in medication consultation for patients with depression: The pharmacists' confidence scale about medication consultation for depressive patients (PCMCD)

A non-randomized, controlled, interventional study to investigate the effects of community pharmacists' cognitive behavioral therapy-based interventions on medication adherence and relevant indicators in patients with depression

BACKGROUND

The prevalence of depression is increasing in Japan. Pharmacists play an important role in helping patients use medicines effectively. Several studies had investigated the impact of community pharmacists on patient adherence to antidepressant therapy, and their results indicated that further study was warranted.

METHODS

This study was conducted from June 2019 to May 2020 using a cluster non-randomized, open-label, parallel-group design. Four community pharmacy stores in Osaka and Hyogo Prefectures, Japan, participated in the study, and enrolled patients with unipolar depression. In the intervention group (IG), patients received cognitive behavioral therapy (CBT)-based medication support, and their medication adherence and adverse drug reactions were monitored by telephone. In the control group (CG), the pharmacists engaged in routine interactions with the study participants. Before participating in this study, the intervention-group pharmacists attended a 5-hour training session on CBT-based medication support. The primary outcome of this study was medication adherence, assessed using the Drug Attitude Inventory (DAI)-10. Secondary outcomes included the changes from baseline at 6 months in the following variables: the Patient Health Questionnaire (PHQ)-9 total score, the EQ-5D-5 L (Euro-QOL 5 dimensions 5 levels) score, patient satisfaction, and the Pharmacists' Confidence Scale about Medication Consultation for Depressive Patients (PCMCD) score.

RESULTS

Four pharmacies (two in IG and two in CG) completed the intervention period. Results were obtained from 19 patients in the IG and 12 patients in the CG. In the IG, the mean DAI-10 score increased from 4.941 at baseline to 6.105, the mean PHQ-9 score decreased from 9.263 to 8.625, and the mean patient satisfaction score increased from 39.947 to 42.211. In the CG, the mean DAI-10 score decreased from 6.333 to 4.167, the mean PHQ-9 score increased from 9.333 to 12.923, and the mean patient satisfaction score decreased from 38.929 to 38.167.

CONCLUSION

CBT-based medication support provided by community pharmacists may improve patient medication adherence to antidepressant therapy and symptoms. Such support can be expected to facilitate better treatment of depressed patients and may also allow the duration of treatment to be shortened.

Pharmaceutical Care in Depression: A Survey of Stigma, Confidence, Attitudes, and Barriers

Purpose

Patients with depression are in high need of optimal pharmaceutical care as they have poor quality of life and functioning. However, little is known about the delivery of pharmaceutical care to patients with depression in Egypt. This study aimed to detect pharmacists' stigma of patients with depression, assess attitudes toward providing depression care, evaluate pharmacists' confidence with depression medication consultation, and identify barriers in providing pharmaceutical care to patients with depression.

Methods

A cross-sectional survey was posted on the social media websites of Egyptian pharmacists' groups and associations. The survey collected pharmacists' demographic information, then measured their confidence in medication consultation through the Pharmacists' Confidence scale about Medication Consultation for Depressive Patients (PCMCD), with items to assess stigma of patients with depression and attitudes toward providing care to patients with depression compared with other physical conditions. The pharmacists were also asked about the barriers to providing pharmaceutical care to patients with depression.

Results

Totally, 86 pharmacists completed the survey: 56 (65.1%) were aged 30 years or older, and 64 (74.6%) had more than five years of experience. The stigma of patients with depression was generally low. The mean (SD) PCMCD score was 51.4 (6.6), reflecting that most pharmacists were confident about medication consultation for patients with depression. Attitudes toward providing pharmaceutical care to patients with depression were generally positive but significantly lower than those reported for patients with other conditions. Lack of education on mental health was the most commonly reported barrier (81.2%) to providing pharmaceutical care to patients with depression.

Conclusion

Participants were confident about medication consultation with a positive attitude toward providing pharmaceutical care. Frequent mental health educational courses, tools, and other methods of consistent engagement that enhance practice, behaviors, and outcomes should be considered for Egyptian pharmacists to improve pharmaceutical care provided to patients with depression.
