RN2LOP01 - OR Changeover Times
General Material Data Vendor Master (General Section)This documentation is copyright by SAP AG.
Purpose
OR changeover time statistics provide an overview of the changeover time between time stamps. Changeover time statistics are used as part of process optimization, unused resources can therefore be avoided.
The changeover time is the interval between the end of one surgery and the start of a new surgery. Changeover times can be determined for all time durations (transaction N2ZP, column "Type" = D) defined in Customizing. The evaluation algorithm inverts these durations as changeover times.
Example: The "incision-suture" duration leads to a changeover time of "suture surgery A - incision surgery B". In this way the evaluation inverts the duration of a selected time stamp as a "changeover time".
Integration
Prerequisites
Features
Selection
You can restrict the evaluation by institution, evaluation period and operating room. If you select the operating room, the building category is a required entry.
You can select whether only main surgeries are evaluated or whether main and secondary surgeries are evaluated together. Enter the suitable time stamp in accordance with this selection. You should ensure that the selected time stamps suit each other if you combine main and secondary surgeries for an evaluation (example: main surgery incision-suture time, secondary surgery incision-suture time).
Institution, evaluation period and time stamp are required entries for the main surgery.
Shift times
In the personnel shift times section you can enter the times for the start and end of the regular or late shift. Times outside of the regular and late shifts are considered on-call.
If the start of the regular shift contains the value 00:00:00, this means that the regular shift starts at 00:00. If the end of the regular shift contains the value 00:00:00, this means that no regular shift has been defined. If the regular shift is to end at midnight, enter 24:00:00 as the end of the regular shift.
If the end of the late shift contains the value 00:00:00, this means that no late shift has been defined. If the late shift is to end at midnight, enter 24:00:00 as the end of the late shift.
If you do not define any shift times, all fields must contain the value 00:00:00. All surgeries will then be evaluated as on-call.
If you select Include Plant Calendar, the system will add Saturdays, Sundays and public holidays to on-call duty.
You use the checkbox in front of the weekdays to explicitly define the weekdays that the evaluation is to be performed for. You also have to do this if you do not define any personnel shift times. The default setting is the definition of all working days. You can however define any other combination and save it in a selection variant. The system does not evaluate data for a weekday which has not been checked.
Standard Variants
Output
The changeover time is assigned to the preceding surgery. The system determines which shift a changeover time belongs to using the statistics-relevant time of previous surgery.
The evaluated changeover times are specified together with the "pair of patients" concerned and are grouped by date and operating room. For secondary surgeries there is the special feature that the same patient belongs to the two adjoining surgeries. You have the option to branch to the surgery monitor using the hotspot on the patient's name, this enables you to view the details for a secondary surgery for an evaluation with secondary surgeries. If a secondary surgery exists for a principal surgery, the relevant patient is flagged by "(P)" for a principal surgery and a "(S)" for a secondary surgery.
For overlapping changeover times (e.g. anesthesia end for surgery 1 overlaps with anesthesia start 2), the system displays the individual duration in the detailed display as negative. Negative values for changeover times do not go into the total, instead they are calculated as a changeover time with the value zero during totaling.
For changeover times which have the value zero, this value is displayed as a blank in the row with the corresponding surgeries.
Surgeries which do not have any time specifications cannot have any changeover times calculated for them.
Taking personnel shift times into account
The system outputs changeover times from the start of a shift to the first surgery within the shift time ("Start Time"), then from surgery to surgery, and then from the last surgery to the end of the shift time ("End Time"). The system does not group "Start Times" and "End Times" separately in the evaluation, instead you can identify them by the chronologically displayed changeover sequence.
Changeover times, which exceed a shift time boundary are assigned to a shift time according to the statistics-relevant time of the preceding surgery. A changeover time which exceeds the shift time boundary is cut at this boundary into an "end time" which still belongs to the shift time and into a "start time" which belongs to the next shift time.
A shift time (mainly the on-call shift) always ends at the 00:00 boundary and a new shift time begins which belongs to the next day. The result of this is that this shift (mainly the on-call shift) can occur twice within 24 hours and can therefore have two start times and two end times.
If a surgery exceeds the shift time boundary and it still belongs to the first shift time due to the statistics-relevant time, the changeover time relating to the shift time is then zero. The start time of the succeeding shift is shortened by the amount of time that the previous surgery extends into the succeeding shift. The shortened start time is flagged by "(-)" behind the "Start of Shift" text
If a surgery exceeds the 00:00 boundary and it still belongs to the previous day due to the statistics-relevant time, the changeover time relating to the shift time on the previous day is then zero. The start time of the following day is shortened by the amount of time that the previous surgery extends into the following day. The shortened start time is flagged by a "(-)" behind the "Start of Day" text
