Many ICU interventions involve complex technical procedures or sophisticated mechanical devices [ eg extracorporeal membrance oxygenation (ECMO), continuous venovenous hemofiltration (CVVH), high-frequency oscillatory ventilation (HFOV)] that have a steep learning curve and that undergo almost continual evolution through the 'tinkering' of skilled and creative clinicians.
Many interventions that involve parents do not measure parental change, nor is it clear which intervention components are associated with improved parental outcomes.
Many self-management interventions involve group-based support or one-to-one consultations; a less expensive delivery option is potentially by telephone.
Many of these interventions involve online discussion boards, also known as discussion forums [ 3], to allow users to communicate with other likeminded peers.
Because system wide interventions involve many players and sub-systems in complex webs of interaction (both formal and informal), the pathways and impacts of these interventions are inherently unpredictable.
Many intervention studies involving HCDs and either exercise or drugs have been conducted to assess changes in abdominal fat distribution in obese subjects.
First, our incremental theory intervention involved many different activities some involving neuroscience, others involving peers, and still others involving discussions with teachers.
Second, many problems or behaviors that affect wellbeing do not require lengthy or complex interventions involving consultations, workshops, training, or support.
