Provider Perceptions of Neuromuscular Blockade in ARDS

2017-06-07 21:23:21 | BioPortfolio


The proposed study will use qualitative methodology to understand health care provider perceptions of neuromuscular blockade (NMB) in patients with Acute Respiratory Distress Syndrome (ARDS). To achieve this goal the investigators will conduct a prospective ancillary study at four clinical centers participating in the NHLBI PETAL network as part of the ROSE (Reevaluation of Systemic Early Neuromuscular Blockade) clinical trial (NCT02509078). Using thematic content analysis of semistructured interviews with health care providers caring for patients enrolled in the ROSE trial the investigators will determine the barriers to NMB use and develop a framework for future NMB adoption in ARDS.


Efficient translation of clinical trial results into practice is an enduring challenge in critical care, with many critically ill patients not receiving evidence-based therapies proven to save lives. One approach to speed the translation of clinical trial evidence into practice is through qualitative research to better understand the barriers to evidence-based care and help design innovative interventions to overcome those barriers.. This work need not wait until the clinical trial is complete—an emerging literature highlights the value of qualitative research concurrent with the conduct of a clinical trial. Such research has several potential benefits, including facilitating implementation of the intervention in the real world, identifying the potential mechanism of action, and identifying contextual factors necessary for the treatments effectiveness.

The Reevaluation Of Systemic Early Neuromuscular Blockade (ROSE) study, conducted by the NHLBI PETAL Clinical Trials Network, is an ideal trial for which to perform a concurrent qualitative implementation study (NCT02509078). NMB has the potential to substantially reduce mortality in ARDS. Yet NMB remains incompletely adopted for reasons that are poorly understood but likely relate to clinical equipoise, historical concerns about safety, and the inherent difficulties in providing complex practices in the intensive care unit (ICU). A better understanding of provider views regarding NMB will provide essential data to aid interpretation of study results and design an implementation study should ROSE demonstrate a survival benefit with NMB.

To examine this issue the investigators will perform a prospective qualitative study using semi-structured interviews health care professionals providing direct care for patients enrolled in ROSE. A trained research coordinator will perform semi-structured interviews with consenting participants. Interviews will be transcribed and uploaded into commercially available qualitative data software. Trained qualitative researchers will read and code each interview based on Consolidated Framework for Implementation Research, a widely accepted conceptual theory of evidence-uptake.

Medical and Biotech [MESH] Definitions

The intentional interruption of transmission at the NEUROMUSCULAR JUNCTION by external agents, usually neuromuscular blocking agents. It is distinguished from NERVE BLOCK in which nerve conduction (NEURAL CONDUCTION) is interrupted rather than neuromuscular transmission. Neuromuscular blockade is commonly used to produce MUSCLE RELAXATION as an adjunct to anesthesia during surgery and other medical procedures. It is also often used as an experimental manipulation in basic research. It is not strictly speaking anesthesia but is grouped here with anesthetic techniques. The failure of neuromuscular transmission as a result of pathological processes is not included here.

The use of peripheral nerve stimulation to assess transmission at the NEUROMUSCULAR JUNCTION, especially in the response to anesthetics, such as the intensity of NEUROMUSCULAR BLOCKADE by NEUROMUSCULAR BLOCKING AGENTS.

Various salts of a quaternary ammonium oxime that reconstitute inactivated acetylcholinesterase, especially at the neuromuscular junction, and may cause neuromuscular blockade. They are used as antidotes to organophosphorus poisoning as chlorides, iodides, methanesulfonates (mesylates), or other salts.

A directed conversation aimed at eliciting information for psychiatric diagnosis, evaluation, treatment planning, etc. The interview may be conducted by a social worker or psychologist.

Cetyltrimethylammonium compounds that have cationic detergent, antiseptic, and disinfectant activities. They are used in pharmaceuticals, foods, and cosmetics as preservatives; on skin, mucous membranes, etc., as antiseptics or cleansers, and also as emulsifiers. These compounds are toxic when used orally due to neuromuscular blockade.
