BACKGROUND: Pulmonary embolism (PE) can be difficult to diagnose in elderly
patients because of the coexistent diseases and the combination of drugs that
they have taken. We aimed to compare the clinical diagnostic values of the Wells
score, the revised Geneva score and each of them combined with D-dimer for
suspected PE in elderly patients. METHODS: Three hundred and thirty-six patients
who were admitted for suspected PE were enrolled retrospectively and divided into
two groups based on age (?65 or <65 years old). The Wells and revised Geneva
scores were applied to evaluate the clinical probability of PE, and the positive
predictive values of both scores were calculated using computed tomography
pulmonary arteriography as a gold standard; overall accuracy was evaluated by the
area under the curve (AUC) of receiver operator characteristic curve; the
negative predictive values of D-dimer, the Wells score combined with D-dimer, and
the revised Geneva score combined with D-dimer were calculated. RESULTS:
Ninety-six cases (28.6%) were definitely diagnosed as PE among 336 cases, among
them 56 cases (58.3%) were ?65 years old. The positive predictive values of Wells
and revised Geneva scores were 65.8% and 32.4%, respectively (P < 0.05) in the
elderly patients; the AUC for the Wells score and the revised Geneva score in
elderly was 0.682 (95% confidence interval [CI]: 0.612-0.746) and 0.655 (95% CI:
0.584-0.722), respectively (P = 0.389). The negative predictive values of
D-dimer, the Wells score combined with D-dimer, and the revised Geneva score
combined with D-dimer were 93.7%, 100%, and 100% in the elderly, respectively.
CONCLUSIONS: The diagnostic value of the Wells score was higher than the revised
Geneva score for the elderly cases with suspected PE. The combination of either
the Wells score or the revised Geneva score with a normal D-dimer concentration
is a safe strategy to rule out PE.
