The risk of TF varied between 1.8% (95% CI 0.4–5.1) and 12.4% (95% CI 7.9–18.4) for SP and 21.4% (95% CI 15.9–27) and 39.3% (95% CI 32.5–46.4) for VSP depending on the definition applied. Higher rates were associated with early changes in therapy by clinician in the absence of an obvious clinical rationale. Non‐adherence to treatment guidelines was observed for 70/169 (41.4%) and 67/201 (33.3%) of children with SP and VSP, respectively. Among children with SP, adherence to treatment guidelines was associated with the presence of wheeze on initial assessment (<italic>P</italic> = 0.02), while clinician non‐adherence to guideline‐recommended treatments for VSP tended to occur in children with altered consciousness (<italic>P</italic> < 0.001). Using propensity score matching to account for imbalance in the distribution of baseline clinical characteristics among children with VSP revealed no difference in TF between those treated with the guideline‐recommended regimen <italic>vs</italic>. more costly broad‐spectrum alternatives [risk difference 0.37 (95% CI −0.84 to 0.51)].</p> </sec> <sec id="tmi12368-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Before revising current pneumonia case management guidelines, standardised definitions of TF and appropriate studies of treatment effectiveness of alternative regimens are required.</p> </sec> </abstract>
