About the PhD thesis
Knee replacement surgery is a frequently performed surgical procedure. The care of patients is organised around viewing the patient as an active participant with increased responsibility for managing their own care and rehabilitation postoperatively. Adequate information and guidance from health care professionals are fundamental care needs of the patients to help them manage their conditions and obtain the best possible outcomes. Some patients effectively manage pain and functional disability during their postoperative rehabilitation. Others, however, experience inadequate improvement in pain and function and require enhanced care to manage their conditions.
The overall aim of this thesis was to investigate the potential of identifying patients with enhanced care needs. Four studies were conducted as part of the thesis research. Study I was a systematic review to identify and synthesise knowledge of how the patients experience pre- and post-operative information provided by health care professionals. Study II was a descriptive correlational study using the Oxford knee score (OKS) as a proxy measure to identify the best predictors of patients who are likely to have enhanced care needs. Study III was a retrospective observational cohort study aiming to assess the potential of dividing the OKS into subscales for predicting clinically meaningful changes in pre- and postoperative pain and function. Study IV was a developmental study investigating whether machine learning models can be used to identify patients without clinically meaningful changes in pain and function who are likely to have enhanced care needs for managing pain and function.
The findings of the thesis pointed to the importance of early identification of patients with enhanced care needs for managing pain and functional limitations. The developed prediction models seem promising for identifying patients with inadequate improvement in pain and function who are likely to have enhanced care needs. Further studies should be undertaken to improve and validate the prediction models before implementation in clinical care.
