Study on optimal utilization of Operation Theater

A study on Optimum Utilization
Of Operation Theater

Aim of study:
To maximize use of all resources of operation theater to improve its efficiency.

Objectives:
To find out gaps in process flow
To find out Turn Around Time in OT
To count utilization hours of OT
To measure cancelation & delayed rate
To collect data on unplanned surgeries
To calculate opportunity loss

Research Methodology:
Research Design: Exploratory design & descriptive study
Sources of Data:
Sample Size: My universe for study was 165 patients (based on average monthly surgeries). I took random sampling of 103 patients over a period of 20 days i.e.62%.
Sampling Process:

Graphical & Statistical analysis of Study:
Avg. OT Utilization in % (last six months)

Interpretation:
Cancellation rate v/s booking rate
Delayed rate
Unplanned surgeries
Excessive unnecessary booking of OT hours
~Utilized
37%

~Utilized
24%

OT 1 & 2

OT 3, 4 & 5

Time Motion Analysis:
I did hypothesis on Time Motion Study in that I had considered Wheel in time,
Reaching time to OT table, Wheel out time OT, Wheel out time recovery.
Null hypothesis is 10 min for Time difference between Wheel in time & Reaching time to OT table & it was rejected.
Null hypothesis is 30 min for Time difference between Wheel out time OT & Wheel out time Recovery & it was rejected

Opportunity Loss:
Apollo OT charge per Hour = Rs 2500
Opportunity loss due to cancellation = Unutilized Hours * Rs. 2500
= 249*2500
= Rs. 6, 22,500 (for 15 days)
