Clinical assessment of speech correlates well with lung function during induced bronchoconstriction.

Tayler N, Grainge C, Gove K, Howarth P, Holloway J - NPJ Prim Care Respir Med (2015)

Bottom Line: There were no significant differences between professionals grouped by seniority or speciality.Speech can intuitively be estimated by health care professionals with moderate accuracy.This gives an evidence basis for the assessment in speech in acute asthma and may provide a new avenue for monitoring.

ABSTRACT
Clinical assessment of asthma often includes a crude assessment of speech, for example whether the patient can speak in full sentences. To date, this statement, despite appearing in national asthma guidelines, has not been related to lung function testing in asthma exacerbation. Seven asthmatics underwent a bronchial challenge and were then recorded reading a standardised text for 1 min. The recordings were played to 88 healthcare professionals who were asked to estimate FEV1% predicted. Health care professionals' estimations showed moderate correlation to FEV1% predicted (rho=0.61 P<0.01). There were no significant differences between professionals grouped by seniority or speciality. Speech can intuitively be estimated by health care professionals with moderate accuracy. This gives an evidence basis for the assessment in speech in acute asthma and may provide a new avenue for monitoring.

fig1: Actual and median estimated values of FEV1% predicted. Figure shows the FEV1% predicted of each recording, accompanied by the median estimated value and interquartile range for each track. FEV1, forced expiratory volume in 1 s.

Mentions: Estimated FEV1 from listening to speech showed a moderate correlation with measured FEV1 values (rho=0.61, P<0.01). The median absolute difference of assessor’s estimation compared with measured FEV1 was 10.6% (interquartile range 4–21.3%). This is shown in Figure 1.
