The views of health care professionals about selective decontamination of the digestive tract: an international, theoretically informed interview study.

Purpose: Selective decontamination of the digestive tract (SDD) as a prophylactic intervention improves hospital-acquired infection and survival rates. Uptake of SDD is low and remains controversial. This study applied the theoretical domains framework to assess intensive care unit clinicians' views about SDD in regions with limited or no adoption of SDD.

Clinical stakeholders' opinions on the use of selective decontamination of the digestive tract in critically ill patients in intensive care units: an international Delphi study.

Introduction: Selective decontamination of the digestive tract (SDD) is a prophylactic antibiotic regimen that is not widely used in practice. We aimed to describe the opinions of key 'stakeholders' about the validity of the existing evidence base, likely consequences of implementation, relative importance of their opinions in influencing overall practice, likely barriers to implementation and perceptions of the requirement for further research to inform the decision about whether to embark on a further large randomised controlled trial.

Methods: This was a Delphi study informed by comprehensive framework of possible determinants of health professionals' behaviour to study Critical Care practice in four countries.

Comparison of four methods for assessing the importance of attitudinal beliefs: an international Delphi study in intensive care settings.

Objectives: Behaviour change interventions often target 'important' beliefs. The literature proposes four methods for assessing importance of attitudinal beliefs: elicitation frequency, importance ratings, and strength of prediction (bivariate and multivariate). We tested congruence between these methods in a Delphi study about selective decontamination of the digestive tract (SDD).
