Do patients with low back pain remember physiotherapists' advice? A mixed-methods study on patient-therapist communication.

Objectives: The primary aim of this study was to determine if the advice physiotherapists think they provide to patients with low back pain (LBP) is what the patients remember and take away from the clinical encounter. The secondary aim was to determine which factors may influence the retention of this advice.

Methods: The first component of the study used questionnaires completed by patients and therapists after the initial visit. Related questionnaires of patients and therapists were screened for inconsistencies. The second component of the study involved semi-structured interviews.

Results: Ninety pairs of questionnaires were completed. Therapists provided patients with one (N = 90), two (N = 85) or three (N = 51) items of advice regarding the management of their LBP. All patients remembered the first item of advice, 92% remembered a second, and 67% remembered the third piece of advice. All items of advice were deemed either 'relevant' or 'very relevant' by 97% of the patients. After the analysis of 14 interviews, data saturation was reached. Four themes emerged from the data analysis of the interviews: (a) Evaluation type, (b) Exercise factors, (c) Patient concerns about their diagnosis, and (d) Patient expectations.

Discussion: In most cases, patients remembered what therapists told them and considered that the advice provided was relevant. Based on the qualitative data, patients were more likely to remember what therapists said when: (a) shared decision making was used during the initial encounter, (b) prescribed exercises were simple to perform and few in number, (c) patients' concerns about their diagnosis were addressed, and (d) patients' expectations were identified and addressed.
