Intensive communication: four-year follow-up from a clinical practice study

Area of Science:

• Critical Care Medicine
• Health Services Research
• Medical Communication

Background:

• Intensive communication strategies can improve patient outcomes in intensive care units (ICUs).
• Previous studies indicated that intensive communication reduced ICU length of stay and mortality.
• The durability of these effects required further investigation.

Purpose of the Study:

• To assess the long-term durability of an intensive communication intervention in an adult intensive care unit.
• To determine if the observed reductions in length of stay and mortality persisted after the initial study period.

Main Methods:

• A 4-year extension study was conducted, comparing outcomes of 2,361 adult medical patients to pre-intervention (134 patients) and post-intervention (396 patients) cohorts.
• Data collected included the number of communication sessions, ICU length of stay, and mortality rates.
• The study evaluated the consistency and efficiency of communication sessions over time.

Main Results:

• Intensive communication sessions were maintained at a similar frequency (1.5-1.6 per patient) but became more efficient with shorter durations.
• A significant and durable reduction in median ICU length of stay was observed (4 days pre-intervention, 3 days during and post-intervention).
• Intensive care unit mortality showed a significant and durable decrease (31.3% pre-intervention, 22.7% during, and 18% post-intervention).

Conclusions:

• Intensive communication is associated with sustained reductions in ICU length of stay and mortality for critically ill adult medical patients.
• The intervention's effectiveness is maintained even with more efficient application and without mandatory participation from non-direct caregivers.
• This approach supports appropriate use of advanced supportive technology, continuing it for survivors and withdrawing it when ineffective.
