Costs in primary care of investigating symptoms suspicious of cancer in a defined population.

OBJECTIVES

To calculate total cost of investigating symptoms related to one of the four most common cancers: prostate, breast, colorectal, and pulmonary. Special attention was given to two non-specific and common symptoms: vertigo/dizziness and tiredness/fatigue.

DESIGN

Retrospective examination of patient records in a defined population.

SETTING

Primary health care (PHC) and hospital care.

MAIN OUTCOME MEASURES: Investigation costs of selected ICD codes.

RESULTS

In total 6812 patients with 14,541 ICD codes were investigated to a total cost per registered ICD code, with one of the selected diagnostic measures, of SEK 800. Some 50% of the costs were due to X-ray examinations of which colonic X-ray was the most expensive single procedure. Symptoms related to colorectal cancer were the most expensive to investigate with vertigo/dizziness and tiredness/fatigue examined separately. Tiredness/fatigue symptoms cost SEK 395 and vertigo/dizziness SEK 197 per registered code to investigate and none of them yielded a detected malignancy. The incidence of cancer was 0.7%. The average cost of diagnosing one malignancy was SEK 236,700, if all diagnostic activities could be justified only for detection of malignancies.

CONCLUSION

A high cost of diagnosing malignancy can be expected and justified, but many symptoms presented in PHC, such as tiredness/fatigue and vertigo/dizziness, have a relatively high investigation cost but detected no case of cancer in this study.
