1 · What the graph read from 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.

2 · The registry

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

objectiveTo determine whether there was an increase in payments for neurologist-prescribed drugs, we performed a retrospective analysis of prescription claims in the Medicare Part D Prescriber Public Use Files from 2013 to 2017.

methodsWe included claims prescribed by providers with the taxonomy "neurology" and included drugs present in all 5 years. Drugs were designated in 2013 as generic (GEN), brand name only (BNO), and brand name prescribed even though a generic equivalent is available (BNGE). To observe payment trends, the percentage change in the per claim payment was compared between drug classes.

resultsWe included 520 drugs, of which 322 were GEN, 61 were BNO, and 137 were BNGE, representing 90,716,536 claims and generating payments of $26,654,750,720. While the number of claims from 2013 to 2017 increased only 7.6%, the total payment increased 50.4%. Adjusted for inflation, claim payments for GEN drug increased 0.6%, compared to significant increases in BNO and BNGE drugs of 42.4% and 45.0% (

conclusionsPayments for neurologist-prescribed brand name, but not generic, drugs in Medicare Part D increased consistently and well above inflation from 2013 to 2017. Unless the overall trend stabilizes or is reversed or high cost-to-claim drugs are addressed, this trend will place an increasing burden on the neurologic Medicare budget.
