[Assessment of the severity of postoperative complications from the patient and doctor perspective]

Abstract

Aim of the study: This study compares doctors' and patients' assessments of the severity of postoperative complications reported by patients. Within the context of quality assurance and patient safety, the study aims to contribute to developing instruments to include patients' views for measuring postoperative complications.

Methods: In a questionnaire development study 474 patients who had undergone different kinds of surgery were given a questionnaire and asked whether postoperative complications occurred, and if so, to describe these complications in free text and assesses their severity as "slight, temporary" or "extensive". In an additional study, the patients' written descriptions of their complications were presented independently to two doctors (general practitioner [GP], orthopaedic surgeon) who were asked to assess the severity from their point of view. The physicians were not aware of the patients' or the other physician's assessments.

Results: 23.5 % of the patients participating in the survey reported postoperative complications in the questionnaire. Feedback from 80 of these patients included sufficient information for data analysis concerning the study's aim, including the description of their complication in free text. 47 (58.7 %) of these patients assessed their postoperative complications as being "slight, temporary", 33 (41.3 %) as being "extensive". The doctors, on the other hand, assessed the severity of the complications described by the patients much less often as "extensive" (GP: 20.0 %, orthopaedic surgeon: 11.3 %). In only 4 (12.0 %) of the 33 cases where the patient chose "extensive" both doctors also chose the assessment item "extensive". In 10 cases (30.3 %), one doctor's "extensive" assessment matched the patient's assessment, and in 19 cases (57.6 %) the patients but none of the doctors assessed the complications as being "extensive". There was a higher correlation between the GP's and the patients' assessments than between the orthopaedic surgeon's and the patients' ratings. Examples of patients' descriptions of their postoperative complications in free text as well as the corresponding assessments of patients and doctors are presented.

Conclusions: Patients' views and assessments of postoperative complications are different from doctors' views. Adequate instruments for measuring the occurrence and severity of postoperative complications should be developed bringing the patients' perspectives into the doctors' assessments. Also, it might be useful to include questions addressing information received pre- and postoperatively about the expected postoperative course as well as communication with patients in the case of complications.
