GP and patient predictions of sick-listing duration: how well do they correspond? A prospective observational study.

OBJECTIVE

To explore how well physicians and patients predict sick-listing duration and the correspondence between their respective predictions. To study possible gender differences concerning prediction accuracy.

DESIGN

Prospective observational study.

SETTING

Two medium-sized primary care centres (PCC) in western Sweden.

SUBJECTS

GPs at the PCCs and attending patients sick-listed for > 14 days.

MAIN OUTCOME MEASURES

Sick-listing duration; patients' and GPs' predictions of the total duration of the individual patient's sick-listing.

RESULTS

A total of 127 patients (93 women, 34 men, mean age 45 years) and 10 GPs participated in the study. Neither the GPs nor the patients were able to predict the interval until return to work with high accuracy. The GPs' and the patients' perceptions concurred in only 26% of cases. There was a significant difference in the correspondence between the GPs' and patients' respective predictions of sick-listing duration compared with the actual duration. GPs' predictions were more accurate for medium-length duration (1.5-6 months), while patients' predictions were more accurate for long-duration (> 6 months) sick-listing. Patients with less education predicted long duration of sick-listing more accurately than those with more education. There was no significant difference between male and female patients' accuracy of prediction, or between GPs' accuracy of prediction of male vs. female patients' sick-listing duration.

CONCLUSIONS

Prediction of total sick-listing duration was hard for both GP and patient; their respective predictions corresponded in only one-quarter of the cases. No gender differences were observed in the accuracy of prediction.
