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.

Abstract

backgroundWith the removal of total knee arthroplasty (TKA) from the Medicare inpatient-only list, outpatient TKA can now be offered, irrespective of payer, in multiple sites. We compared time- and cost-effectiveness of outpatient TKA performed in a hospital outpatient department (HOPD) to that at an inpatient academic medical center (AMC).

methodsWe reviewed all outpatient TKAs performed at our AMC and our HOPD from August 2018 to July 2019. Time efficiency by phase of care was determined, and cost data were obtained from the hospital financial department. Patient selection for outpatient surgery was identical for each site of care.

resultsWe identified 21 knees that had surgery at the HOPD and 65 knees that had surgery at the AMC. Demographics were similar in both groups. The AMC group had significantly longer in-facility to operating room (Δ (difference) = 33.5 minute,

conclusionsOutpatient TKAs performed in an HOPD spend significantly less time within the facility than the ones performed in an AMC and cost significantly less. It is expected that approval of Medicare TKAs at ambulatory surgery centers will further improve cost and efficiency.
