Table 1 Introduction and score calculation method of AQI indicators
Indicators | Illustration | System configuration | Full score | Scoring formula |
|---|---|---|---|---|
Basic information | Patients'name,sex,age,height,weight,operation name, ASA classification, the formula and parameters of the analgesia pump, etc Number of basic information completed = maximum number of configurations -(number of unfilled basic information/number of patients) | Maximum:9.00 Minimum:0.00 | 10.00 | 10–10 × ((9- Number of basic information completed)/9) |
Average pressing times | Average pressing times = total pressing times/number of patients | Maximum:0.50 Minimum:0.00 | 5.00 | 5–5 × ((0.5- Average pressing times)/0.5) |
Evaluation rate | Evaluation rate = total number of evaluations/number of patients | Maximum:1.00 Minimum:0.00 | 15.00 | 15–15 × ((1- Evaluation rate)/1) |
Poor analgesia rate | Patients effectively press the automatic control button more than 4 times within 1 h Poor analgesia rate = total number of poor analgesia alarms/number of patients | Maximum:0.05 Minimum:0.00 | 10.00 | 10 × ((0.05- Poor analgesia rate)/0.05) |
Insufficient analgesia rate | Invalid pressing times ≥ 3 in one lock time. Insufficient analgesia rate = total number of analgesia insufficiency alarms/number of patients | Maximum:0.13 Minimum:0.00 | 10.00 | 10 × ((0.13- Insufficient analgesia rate)/0.13) |
insufficient analgesia treatment time | From the alarm of insufficient analgesia immediately to the treatment is completed and recorded in the system Insufficient analgesia treatment time = total treatment time/number of insufficient analgesia alarms | Maximum:120.00 min Minimum:30.00 min | 10.00 | 10 × ((120- Insufficient analgesia treatment time)/90) |
The rate of not power off after pump withdrawal | After pump withdrawal operation in the system, infusion is still recorded and PCA pump is still running The rate of not power off after pump withdrawal = Number of patients with infusion records after pump withdrawal/total number of patients | Maximum:0.50 Minimum:0.00 | 5.00 | 5 × ((0.5- The rate of not power off after pump withdrawal)/0.5) |
The rate of leaving service area | The patient side (PCA pump) leaves the local area network or the system failure that causes an alarm of leaving the service area, so that the patient's use of PCA pump cannot be observed in real time The rate of leaving service area = number of alarms of leaving service area/number of patients | Maximum:0.50 Minimum:0.10 | 5.00 | 5 × ((0.5- The rate of leaving service area)/0.4) |
Bubble incidence | Bubble incidence = total number of bubble alarms/number of patients | Maximum:0.50 Minimum:0.10 | 10.00 | 10 × ((0.5- Bubble incidence)/0.4) |
Blockage rate | Blockage rate = total number of blockage alarms/number of patients | Maximum:0.50 Minimum:0.10 | 10.00 | 10 × ((0.5- Blockage rate)/0.4) |
Drug utilization rate | Drug utilization rate per patient = input quantity/total solution Average drug utilization rate = total drug utilization rate/number of patients | Maximum:0.67 Minimum:0.50 | 10.00 | 10–10 × ((0.67- Average drug utilization rate)/0.17) |
