Over half of elective surgery cancellations in Major Ambulatory Surgery (MAS) units are preventable. Improving patient selection and resource management can reduce these disruptions and optimize surgical scheduling.
Area of Science:
- Health Services Research
- Surgical Management
- Healthcare Operations
Context:
- Major Ambulatory Surgery (MAS) units are crucial for efficient healthcare delivery.
- Minimizing elective surgery cancellations is a key performance indicator for hospital management.
- Understanding cancellation patterns is vital for operational improvement.
Purpose:
- To analyze the incidence and reasons for surgical cancellations in a Major Ambulatory Surgery unit.
- To identify preventable factors contributing to elective surgery cancellations.
- To provide recommendations for reducing surgery cancellations and improving resource allocation.
Summary:
- A retrospective study of 16,934 patients in an MAS unit from 1995-2009 revealed 701 (4.1%) cancellations.
- The primary reasons for cancellation included incorrect patient preparation (27.1%), lack of resources (25.2%), and acute intercurrent disease (25.7%).
- Over half (52.6%) of cancellations were deemed avoidable, highlighting significant potential for improvement.
Impact:
- Implementing improved pre-operative assessment protocols can reduce avoidable cancellations.
- Enhanced patient information campaigns can increase awareness of healthcare costs and reduce non-attendance.
- Optimizing resource management and scheduling can lead to more efficient MAS unit operations and better patient outcomes.

Truncation in Survival Analysis
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are observed.
