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

backgroundWe investigated the risk of bloodstream infections (BSI) and ventilator-associated lower respiratory tract (LRT) infections, including pneumonia (VAP) and tracheobronchitis (VAT), due to multidrug-resistant bacteria (MDRB) in colonized critical care patients attended in the medical intensive care unit (MICU) and surgical critical care unit (SCCU).

methodsObservational, unicentric study including 573 consecutive adult patients (median age of 66 years; range, 18–85 years) and comprising a total of 585 admissions. Universal MDRB screening cultures (from nasal, pharyngeal, rectal, and axillary sites) were regularly performed. Blood cultures and (semi)quantitative cultures of endotracheal or bronchoscopic specimens were performed and interpreted following consensus guidelines.

resultsColonization by MDRB was documented in 201 out of 585 admissions (34.4%), in which 261 MDRB were isolated, most frequently extended-spectrum beta-lactamase (ESBL)-producing Enterobacterales (n = 102) followed by MDR-S. maltophilia (n = 45), carbapenemase-producing Enterobacterales (n = 40), MDR-Gram-positive bacteria (n = 35), and MDR-P. aeruginosa (n = 28). There were 21 MDRB BSI, mostly caused by Gram-negative bacteria (95.8%). Colonization by MDRB was independently associated with subsequent MDRB BSI (HR14.1; 95% CI, 3.29–60.65 P < 0.001). MDRB were recovered in 157/430 admissions requiring invasive mechanical ventilation (36.5%) and there were 25 episodes of ventilator-associated LRT infections due to MDRB, mostly MDR-Gram-negative bacteria. Colonization by MDRB was independently associated with subsequent MDRB LRT infections (HR, 6.59; 95% CI, 2.67–16.26; P < 0.001).

conclusionMDRB colonization is a significant risk factor for the occurrence of MRDB-matched invasive infections in a mixed cohort of MICU and SCCU patients. MDRB screening cultures using a multi-site sampling approach may be useful for tailoring empirical antimicrobial treatments on an individual basis.
