Background and objectives: Up until recently no tool for quality assurance (QA) of outpatient pain therapy after outpatient surgery, which currently constitutes one third of all operations, was available with benchmarking capacity. The QUIPS (German abbreviation for quality assurance in postoperative pain therapy) questionnaire, that had primarily been developed and established for inpatient postoperative pain therapy, was to be optimized to not only incorporate the issues with regard to outpatient operations but also a revision for use in the clinical routine.
Material and methods: An interdisciplinary task force reviewed and optimized the QUIPS questionnaire. The optimized questionnaire was then used within the scope of outpatient surgery in their clinics. A total of 121 patients and 12 surgeons received a questionnaire on the first postoperative day containing questions on acceptance and understandability of the QUIPS patient outcome questionnaire.
Results: Of the patients 12 (9.9 %) did not understand the original question on special pain therapy procedures stated during the preoperative counseling. For 15 patients (12.4 %) the original questions on chronic or pre-existing pain were misleading and 4 out of the 12 surgeons (33 %) did not conclusively understand these questions. The optimized questionnaire modified the questions in the preoperative counseling in the segment of postoperative pain as follows: question E1 was changed to a yes/no answer. Question E13 was modified to "how content were you with respect to your post-operative pain therapy?" Question E14 was modified to "did you suffer from other pain prior to the operation, hence pain that continued in addition to the postoperative pain?" These changes improved the understandability of the QUIPS patient outcome questionnaire. Surgeons required on average 9.7 min (SD ±3.2 min) to complete the QUIPS documentation sheets and 83 % of the surgeons rated the optimized QUIPS module as usable in the daily routine. The new module QUIPSambulant will soon be available for download on the QUIPS internet website.
Discussion: By reducing items on the QUIPS documentation sheets with respect to items relevant for outpatient surgery and redesigning three questions in the patient outcome questionnaire, a new QUIPS module for the QA of postoperative pain in an ambulatory setting is now available for both patients and surgeons. The necessity for quality management (QM) with regard to postoperative pain therapy after outpatient surgery can be considered assured. To what extent the newly adapted QM tool QUIPSambulant will be deemed suitable in a routine hospital setting remains to be seen and requires ongoing investigation.
