Determination of drug-related problems among type 2 diabetes outpatients in a hospital in Vietnam: A cross-sectional study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDrug-related problems (DRPs) are common in clinical practice and occur at all stages of the medication process. The major factor contributing to DRPs is prescription, although patients' poor adherence to treatment is also a significant factor. This study evaluated type 2 diabetes outpatients in a hospital in Vietnam for drug-related problems (DRPs) and related variables.
methodsA cross-sectional descriptive study was conducted on 495 outpatients who met the criteria and 157 people agreed to participate in the interview. Medication order review and medication adherence review were used to identify DRPs. The types of DRP were based on the Pharmaceutical Care Network Europe (PCNE) categories version 9.0. The identification and assessment DRPs were carried out by clinical pharmacists and get agreed upon by physicians who had not directly prescribed patients who participated in the study.
resultsA total of 762 DRPs were identified via prescribing review process, the average number of DRP on each prescription was 1.54±1.07, while 412 DRPs were determined through patient interviewing. The most frequent DRPs were "ADR (Adverse Drug Reaction) occurring" (68.8%). The main causes were "patient is unable to understand instructions properly" or "patient is not properly instructed", "patient stores insulin inappropriately", "patient decides to use unnecessary drugs" and "patient intentionally uses/takes less drug than prescribed or does not take the drug at all for whatever reason" which accounted for 65.0%, 41.4%, 38.2%, and 28.7%, respectively. From the prescribing review, the most observed DRPs were "Inappropriate drug according to guidelines/formulary" and "No or incomplete drug treatment in spite of existing indication", accounting for 45.0% and 42.9%, respectively. There was a significant association between age (OR 3.38, 95% CI: 1.01-11.30), duration of diabetes (OR 3.61, 95%CI: 1.11-11.74), presence of comorbidity (OR 5.31, 95%CI: 1.97-14.30), polypharmacy (OR: 2.95, 95%CI: 1.01-8.72) and DRPs. In patients, poor knowledge of antidiabetic agents was the main reason to lack adherence and occurring ADR (OR 2.73, 95%CI: 1.32-5.66, p = 0.007 and OR 2.49, 95%CI: 1.54-4.03, p = 0.001 respectively).
conclusionDRPs occurred in the prescribing stage and relating to patient's behavior of drug administration was high. Clear identification of DRPs and the associated factors are essential for building the intervention process to improve effectiveness and safety in the treatment of type 2 diabetes mellitus patients.
