The relationship between nurse contact time and patient outcomes: a retrospective observational study using Real-Time...

Area of Science:

• Healthcare Management
• Nursing Research
• Patient Outcomes

Background:

• Previous studies link higher nurse staffing to improved patient outcomes.
• The specific impact of direct nurse-patient contact time on outcomes is not well understood.
• Quantifying actual time spent in direct care is challenging.

Purpose of the Study:

• To investigate the relationship between nurse contact time and patient hospital outcomes.
• To quantify the association between direct nursing care duration and in-hospital mortality.
• To explore the utility of novel data sources for measuring patient-provider interactions.

Main Methods:

• Utilized a Real-Time Location System (RTLS) with Global Positioning System (GPS) sensors to track staff and patient movements.
• Estimated daily patient contact time with nursing staff, distinguishing direct bedside care.
• Analyzed the correlation between contact time and in-hospital mortality rates.

Main Results:

• Patients averaged 8 hours of contact with nurses daily, with 22 minutes of direct bedside care.
• A statistically significant association was found between total daily contact time and in-hospital mortality.
• Each 10-minute increase in daily contact time was associated with a 0.05% reduction in mortality.

Conclusions:

• Direct nurse-patient contact time is a significant factor in hospital patient outcomes.
• Novel tracking technologies can effectively measure patient-provider interaction time.
• Healthcare institutions should prioritize strategies to maximize meaningful patient-nurse contact time.
