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 duration of episodes of intracranial hypertension is related to poor outcome, hence the need for prompt diagnosis. Numerous issues can lead to delays in the implementation of invasive intracranial pressure (ICP) monitoring, thereby increasing the dose of intracranial hypertension to which the patient is exposed. The aim of this prospective, observational, multicenter study was to assess the magnitude of this delay, evaluating the time required for initiation of invasive ICP monitoring, from indication (T1) to initiation of the maneuver (T2) when performed by neurosurgeons compared to intensive care physicians.

methodsWe evaluated the impact of the operator performing the maneuver (neurosurgeon vs. intensivist) on the T2-T1 time interval, where T1 represents the time at which indication for invasive ICP monitoring is declared, and T2 the time at which the maneuver starts, defined as the skin incision. The effect of the operator performing the maneuver was evaluated through a parametric survival model. Both intraparenchymal catheters (IPCs) and external ventricular drains (EVDs) were considered as invasive ICP monitoring devices. Invasive monitoring could be performed in intensive care unit (ICU) or in operating room (OR).

resultsA total of 112 patients were included into the final analysis; 39 IPCs were placed by intensivists within the ICU, and a total of 73 IPCs and EVDs by neurosurgeons both within the ICU and OR settings. The mean difference in T2-T1 time for IPCs placement in the ICU was 69 min (CI 50.1-94.8) in the intensivist group and 145 min (CI 103.4-202.9) in neurosurgeon group. The mean difference between these groups, 76 min, was found to be statistically significant (p-value = 0.0021). In the group treated by neurosurgeons, no statistically significant differences were found in timing between the ICU and the OR.

conclusionsInvasive ICP monitoring performed with IPCs in ICU begins earlier when performed by intensivists rather than neurosurgeons. This finding suggests the possibility to obtain a prompt diagnosis of intracranial hypertension when intensivists intervein directly at patient's bedside. Further studies are needed to confirm these findings and investigate their effect on outcome.
