Abstract

Purpose

Performance status is an important factor in determining quality of life, the choice of treatment, and prognostic tool in patients. All scoring systems currently in use measure the patient’s performance subjectively. A new method of objective assessment of performance ECOG/WHO grades 2 and 3 was constructed and tested.

Methods

A performance meter—an adapted USB data logger with a mercury tilt switch—was constructed. The device was tested in a feasibility study on 33 residents of a retirement home. Parallel to the objective assessment, each resident gave their own estimate of their performance, and each resident was in turn assessed by the nursing staff.

Results

With the performance meter, 4 residents (12%) were assessed as PS ≥ 3 in comparison with 8 (24%) and 7 (21%) residents with an ECOG score ≥ 3 estimated by patients themselves and nursing staff respectively.

Conclusion

Subjective scoring—estimated by patients themselves and by nursing staff—showed underestimation of patients’ performance. In 12% of patients, a better performance score was observed with objective measurement in comparison with subjective assessment. Performance meter could be a useful tool for health care professionals for type of care decisions.
