Compliance With Antidepressant Medication in Treatment of Functional Dyspepsia

February 10, 2015 updated by: Shengliang Chen, RenJi Hospital

Compliance With Antidepressant Medication in Treatment of Functional Dyspepsia: A Randomized Comparison of Different Prescribing Behaviors

The study hypothesis is appropriate clinician-patient communication that provides explanations of the reasons for psychoactive drug prescriptions based on the generation of FD symptoms and the drugs' effects might improve compliance with psychoactive agent regimens among FD patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Antidepressive agents have been proved to be effective in the treatment of functional dyspepsia (FD) patients. However, one of the factors that limit therapeutic benefit is the poor compliance with prescribed drugs. The possible reasons for lack of compliance include the patient's health beliefs (e.g., that people who took such agents is possibly considered insane in China), lack of knowledge about antidepressants (that they are addictive or can be stopped on recovery), and aversion to side effects. The investigators propose to examine whether different clinician-patient communication methods could affect adherence to antidepressant drugs in functional dyspepsia patients.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Compliance of Flupentixol-Melitracen
Time Frame: weeks 1, 2, 4, 8
The patients were asked to keep a diary to record their medication intake. At each visit (weeks 1, 2, 4, 8), the patient bring back the drug bottle and the diary, then the physician recorded the number of pills remaining in the bottle. Pills remained more than 20% at any visit or seven days of consecutive abstinence were adopted as the criterion for identifying therapy noncompliance.
weeks 1, 2, 4, 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Dyspepsia Symptom Questionnaire at Week 8
Time Frame: week 0 and 8
The severity of patients' dyspeptic symptoms were assessed using the Leeds Dyspepsia Questionnaire (LDQ) at week 0 and 8. The LDQ contains eight items about epigastric pain, retro-sternal pain, regurgitation, nausea, vomiting, belching, early satiety and dysphagia with six grades for each item and a sum of the eight symptom scores make the LDQ score.LDQ scores of 0 - 4 were classified as very mild dyspepsia, 4 - 8 as mild dyspepsia, 9 -15 as moderate dyspepsia, and > 15 as severe or very severe dyspepsia. The change of LDQ scores was calculated by LDQ scores of 8 weeks minus baseline, with lower values represent a better outcome.
week 0 and 8
Change From Baseline in Psychiatric Symptom on Hospital Anxiety and Depression Scale at Week 8
Time Frame: week 0 and 8
Each patient was surveyed using the Hospital Anxiety and Depression Scale to assess the psychiatric symptom at week 0 and 8.The HADS consists of 14 items, seven of which assess anxiety, and seven assess depression. The anxiety and depression subscales were calculated independently. The patients were asked to answer each item on a four-point (0 - 3) scale. Scores of 0 to 7 on either subscale can be regarded as within the normal range, scores of 8 to 10 are suggestive of the presence of the respective state, and scores of 11 or higher indicate the probable presence of the respective mood disorder. The change of HADS scores was calculated by HADS anxiety and depression scores of 8 weeks minus baseline, with lower values indicate better outcome.
week 0 and 8

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
