Key Characteristics and Mechanisms in Ventilator Weaning of Adult Intensive Care Patients-A Qualitative Study With Healthcare Professionals.
Article in Nursing in critical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundWeaning from mechanical ventilation appears to be a complex intervention as defined by the Medical Research Council Framework. However, there is a lack of theoretical insights into ventilator weaning, and the underlying causal mechanisms have not yet been uncovered sufficiently. To understand its complexity in theory and develop it in practice, a program theory is currently being developed in a multi-method study.
aimTo identify key characteristics and mechanisms in ventilator weaning of adult intensive care patients. STUDY
designIn this sub-study, we conducted semi-structured group discussions and workshops with 29 healthcare professionals in intensive care over 3 days in 2025 in Germany, using a qualitative design. The data were collected using audio recordings, field notes and photographs. After transcription, a deductive-inductive thematic analysis was performed.
findingsThe analysis revealed four principal themes: (1) complexity of ventilator weaning, (2) outcomes, (3) interventions and (4) links and relationships. The first theme combines factors such as definition and delimitation, dynamics, structure and individualization, which together describe the inherent complexity. The second theme covers different endpoints during the process, including preconditions and postconditions as well as intermediate, immediate and ultimate outcomes. The third theme comprises direct and indirect interventions, as well as nonprogram external factors. The fourth theme explores the connections between interventions, outcomes and contextual factors.
conclusionThe findings of this study support the understanding that ventilator weaning is a complex intervention. The identified interaction of the various interventions, outcomes and contextual factors needs to be theoretically organized and evaluated in future studies. RELEVANCE TO CLINICAL PRACTICE: Identifying the interactions between key characteristics in this process can improve HCPs' sensitivity to the effects of their own actions. A theoretical understanding of the mechanisms underlying ventilator weaning enables the targeted development and evaluation of a complex weaning intervention.
