16 Questions
What percentage of patients had fewer presentations to the Mater Hospital ED for exacerbations of pelvic pain in the 12 months after input from the PPPC clinic?
19%
What was the percentage reduction in the number of ED presentations for patients who were known to be presenters to ED for pelvic pain in the last 12 months?
63.9%
Did the length of stay (LOS) for patients who still presented to ED change after clinic attendance?
It remained the same
What was the percentage reduction in short stay admissions 12 months after clinic attendance?
75.8%
What was the estimated reduction in daily oral morphine milligram equivalents for regular opiate users?
356mg per day
What percentage of women had diagnostic procedures performed in the 12 months following clinic attendance?
1%
Why might there be no significant difference in the number of inpatient admissions despite reductions in ED presentations and explorative procedures?
Staff may be more likely to admit patients for representations related to intervention delivered by the service
What was the significance of the reduction in ED presentations for exacerbations of pelvic pain in the 12 months after input from the PPPC clinic?
p = 0.003
What was the primary outcome of the PPPC clinic's intervention on patients with pelvic pain?
Decreased number of ED presentations for exacerbations
Which of the following parameters showed no significant difference pre- and post-clinic attendance?
Number of inpatient admissions
What was the likely reason for the lack of significant difference in inpatient admissions?
Staff may be more likely to admit patients for representations related to interventions delivered by the service
What was the significance of the X21 value in the analysis?
It was a statistical measure of the significance of the results
Which group of patients showed a significant reduction in daily oral morphine milligram equivalents?
Those who were recognised regular opiate users
What was the outcome of the PPPC clinic's intervention on explorative procedures?
Few women had diagnostic procedures performed
Which of the following is a possible explanation for the results?
Staff may be more likely to admit patients for representations related to interventions delivered by the service
What was the significance of the 95% CI in the analysis?
It provided a range of values within which the true effect of the intervention likely lies
Study Notes
ED Presentation Results
- 19% fewer patients presented to the Mater Hospital ED for exacerbations of pelvic pain in the 12 months after clinic attendance compared to the 12 months prior.
- 63.9% reduction in the number of ED presentations in the 12 months after clinic attendance for patients who were known to be presenters to ED for pelvic pain in the last 12 months.
ED Length of Stay
- No difference in the length of stay for patients who still presented to ED in the 12 months after clinic attendance.
Admissions
- 21% of patients required short stay admissions pre-clinic compared to 7% post-clinic, resulting in a 75.8% decrease in the absolute numbers of short stay admissions.
- No difference in the occurrence of inpatient admissions.
Regular Opiate Use
- Significant reductions in daily opiate use and total daily oral morphine milligram equivalents for patients who were recognized regular opiate users.
- Estimated total reduction in daily oral morphine milligram equivalents of 356mg per day.
Surgery Performed
- Few women had diagnostic procedures performed in the 12 months following clinic attendance (1%).
- No significant change in the overall number of surgical procedures pre- and post-clinic attendance.
Inpatient Admissions
- Despite reductions in ED presentations, explorative procedures, and daily morphine milligram equivalents, there was no significant difference in the number of inpatient admissions.
- Hypothesis: staff may be more likely to admit patients for representations related to intervention delivered by the service (e.g., whilst opiate treatment is actively being weaned or shortly after surgery).
ED Presentation Results
- 19% fewer patients presented to the Mater Hospital ED for exacerbations of pelvic pain in the 12 months after clinic attendance compared to the 12 months prior.
- 63.9% reduction in the number of ED presentations in the 12 months after clinic attendance for patients who were known to be presenters to ED for pelvic pain in the last 12 months.
ED Length of Stay
- No difference in the length of stay for patients who still presented to ED in the 12 months after clinic attendance.
Admissions
- 21% of patients required short stay admissions pre-clinic compared to 7% post-clinic, resulting in a 75.8% decrease in the absolute numbers of short stay admissions.
- No difference in the occurrence of inpatient admissions.
Regular Opiate Use
- Significant reductions in daily opiate use and total daily oral morphine milligram equivalents for patients who were recognized regular opiate users.
- Estimated total reduction in daily oral morphine milligram equivalents of 356mg per day.
Surgery Performed
- Few women had diagnostic procedures performed in the 12 months following clinic attendance (1%).
- No significant change in the overall number of surgical procedures pre- and post-clinic attendance.
Inpatient Admissions
- Despite reductions in ED presentations, explorative procedures, and daily morphine milligram equivalents, there was no significant difference in the number of inpatient admissions.
- Hypothesis: staff may be more likely to admit patients for representations related to intervention delivered by the service (e.g., whilst opiate treatment is actively being weaned or shortly after surgery).
This quiz assesses understanding of the results of a pelvic pain clinic, including the reduction of ED presentations for exacerbations of pelvic pain. It evaluates knowledge of statistical analysis, including confidence intervals and p-values.
