A trend analysis of incidents occurring in a healthcare facility should focus on which of the following areas?

A trend analysis of incidents occurring in a healthcare facility should focus on case mix index and staffing patterns. The case mix index helps to understand the types and complexity of cases being treated in the facility, which can provide insights into potential risk factors for incidents. Staffing patterns are crucial as they directly impact patient care and safety. By analyzing these two areas, healthcare facilities can identify patterns and trends in incidents, allowing them to implement targeted interventions and quality improvement initiatives to enhance patient safety and mitigate risks effectively. The other options do not directly address the core factors that contribute to incident trends in healthcare facilities.
