Generic dispensing rates for substitutable drugs prescribed by general practitioners compared with other private ambulatory specialists: A study based on a French national reimbursement database.

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
backgroundThe use of generic drugs is a way for healthcare systems to reduce costs, particularly in ambulatory care. Several studies suggest that the prescriber's speciality is associated with the use of generic drugs, and that substitutable drugs prescribed by General Practitioners (GPs) are more often generic, but this association has never been studied in France. In the French legislative context, except in rare situations, all substitutable drugs prescribed should be dispensed in generic form.
objectivesCompare the generic drugs dispensing rate among substitutable drugs dispensed in community pharmacies prescribed by French private GPs with that of other private specialists, all other specialities combined (first objective) or each other speciality taken individually (second objective).
methodsWe used a sample of an open available semi-aggregated database from the 2019 French health insurance system database. We compared with logistic regression models GPs to all other specialities combined, then GPs to the 19 other specialties taken individually, only on the substitutable drugs they prescribe in common.
resultsIn 2019, 53.4% of the drugs prescribed by French private ambulatory physicians were substitutable drugs, and 81.5% of them were dispensed in generic form. After adjustment, the generic dispensing rate for substitutable drugs was significantly higher for GPs than for other specialties (ORa 0.74 [IC95% 0.72-0.76]). Thirteen of the nineteen other specialities taken individually, such as endocrinologists (ORa 0.64 [IC95% 0.57-0.72]) and cardiologists (ORa 0.60 [0.56-0.63]) had significantly lower generic dispensing rates than GPs. No other speciality had a rate significantly higher than GPs.
conclusionsSubstitutable drugs prescribed by French private GPs are more often dispensed in generic form than those from other private ambulatory specialties. To understand this result and optimise the use of generic drugs in outpatient settings, we need to study the different stages of drug use, from prescription by the physician to dispensing by the pharmacist and acceptance by the patient.
