Reducing Hospital Toxicity: Impact on Patient Outcomes.

Area of Science:

• Sleep Medicine
• Hospital Quality Improvement
• Patient Engagement

Background:

• Circadian rhythms govern 24-hour biological processes, influencing health.
• Hospital routines often disrupt patient sleep-wake cycles and control over health information.
• Disrupted circadian rhythms negatively affect patient health outcomes.

Purpose of the Study:

• To evaluate interventions aimed at improving circadian rhythms in hospitalized patients.
• To assess the impact of enhanced access to daily health information on patient outcomes.
• To determine if these measures improve overall hospital quality and safety.

Main Methods:

• A 2.5-year study involving 3425 medical-surgical patients.
• Intervention group (1185 patients) received sleep-supportive measures and an inpatient portal for health information.
• Control group (2240 patients) received standard care.

Main Results:

• Intervention patients showed improved sleep quality and quantity.
• Hospital length of stay was reduced by 8.6 hours (P=.04).
• 30- and 90-day readmission rates decreased by 16% and 12% (P≤.02), with higher self-rated mental health (P=0.03).

Conclusions:

• Modest changes to hospital routines can significantly improve the hospital environment.
• Enhancing sleep and patient access to health knowledge improves hospital outcomes.
• Optimizing sleep-wake patterns is a viable strategy for improving hospital quality and patient safety.
