Therapeutic duplicate prescribing in Korean ambulatory care settings using the National Health Insurance claim data.
Article in International journal of clinical pharmacy, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundDuplicate prescribing is known to occur across health systems and is one of the most frequent drug related problems. Therapeutic duplication (TD) increases the risk of adverse drug reactions without additional therapeutic benefits.
objectivesThis study aimed to develop TD criteria concerning four drug categories which are acid-related disorder drugs, antimicrobials, antihypertensives, and lipid modifying drugs and to estimate the prevalence of therapeutic duplicate prescribing at the ambulatory care settings in Korea.
methodsTD criteria were developed using the WHO anatomical therapeutic chemical classification and modified with an expert consensus panel using the Delphi method. The prevalence of TD including ingredient duplication (ID) of four drug categories was examined using National Health Insurance claim database including 15 million patients during one month in 2009 (December). TD was defined as prescribing medications within the same category in the developed TD criteria list.
resultsThe numbers of patients who received acid-related disorder drugs, antimicrobials, antihypertensives, and lipid-modifying drugs in the study period were 10,049,292, 7,584,131, 4,349,945, and 1,425,292 respectively. In the field of acid-related disorder drugs prescribed, there were 0.3 % IDs and 2.5 % TDs within a prescription issued by one prescriber. There were 8.4 % IDs and 14.5 % TDs between prescriptions issued at different ambulatory visits. In the field of antimicrobial medicines, there were 0.1 % IDs and 2.6 % TDs within a prescription, while there were 5.0 % IDs and 7.6 % TDs between different prescriptions. Amongst the antihypertensives prescribed, there were 0.4 % IDs and 1.9 % TDs within a prescription, while there were 9.9 % IDs and 11.5 % TDs between prescriptions. Lastly, looking at lipid-modifying drugs prescribed, there were 0.3 % IDs and 0.5 % TDs within one prescription, while there were 8.9 % IDs and 9.4 % TDs between prescriptions.
conclusionThe prevalence of duplicate prescribing was substantial in the ambulatory care setting which is to be improved using the TD criteria developed from this study in the national drug utilization review system in Korea.
