Abstract
Summary:
Introduction: The present article describes the development
and evaluation of a questionnaire with aid of which patients
can assess the quality of the perioperative phase. Using a
standardized and objective methodology the aim was to
design a simple patient-oriented tool for multidisciplinary
application.
Methods: A total of 397 patients, 64 relatives, and 123 representatives
of various medical disciplines participated in the
development and evaluation of the questionnaire. In seven
steps involving continuing evaluation, 198 potentially relevant
items were condensed to 33 questions covering the
major aspects of perioperative care impacting on the patient,
relatives, medical staff and nursing personnel.
Results: The final version of the questionnaire containing 33
questions that can be answered on a 4-point Likert scale is
presented. Initial results from 126 patients revealed good
patient acceptance of this new instrument. More than 90% of
the patients can complete the questionnaire within 10 minutes.
Internal reliability testing revealed a Crohnbach´s alpha
of 0.79.
Conclusion: The present PPP33 questionnaire differs from
all other instruments used to date, in particular in terms of
the objectivity of its development, its patient orientation and
its comprehensive, multidisciplinary approach. Not only
postoperative somatic disturbances are addressed, but also
all relevant aspects of the entire perioperative period.
Further evaluation must show whether the results obtained
with this new tool correlate with other major endpoints, such
as patient satisfaction.
