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

backgroundThe authorization process and coverage/reimbursement mechanisms for medical devices play critical roles in device adoption and usage. However, international variation in these processes remains poorly characterized, especially with regard to data transparency and the effects of reimbursement on usage.

methodsThis study examined publicly available databases, governmental agency recommendations and policies, and press releases from the United States, Canada, the United Kingdom, and the Netherlands to compare the regulatory approval processes and coverage/reimbursement mechanisms for 2 novel cardiovascular devices introduced in the early and late 2000's: the Watchman left atrial appendage occlusion device and the Impella percutaneous ventricular assist device. In addition to qualitative comparisons for each country, this study compared the date of the first regulatory review, time from submission to review completion, device approval date, agency approval requirements, number of review cycles, and necessity of postapproval studies as determined by the regulator, date of funding decision, final funding decision, and requirements for device reimbursement by relevant government payors.

resultsAuthorization data were easily accessible for the United States and Canada but extremely limited for the United Kingdom and the Netherlands. Chronologically, authorization occurred ≈10 years earlier in Europe (United Kingdom and the Netherlands) than in North America (United States and Canada) for both devices. The United States was the only country where the principal public payor (Medicare) explicitly reimbursed both procedures. The United States was similarly notable for more rapid adoption and higher utilization of both devices than the other countries, with the Watchman implanted at 3.4 devices per 100 000 adults annually and Impella used in 7 to 8 procedures per 100 000 people annually. In contrast, uptake was far lower in Canada and Europe.

conclusionsThis research provides insights into how differences among countries in authorization and reimbursement mechanisms may impact the adoption and usage of medical devices, and may inform future policies on these processes.
