• W4376609160 abstract "<ns4:p><ns4:bold>Background: </ns4:bold>Under-5 pneumonia mortality remains high in low-income countries. In 2014 the World Health Organization (WHO) advised that children with chest indrawing pneumonia, but without danger signs or peripheral oxygen saturation (SpO<ns4:sub>2</ns4:sub>) < 90% be treated in the community, rather than hospitalized. In Malawi there is limited pulse oximetry availability.</ns4:p><ns4:p> <ns4:bold>Methods: </ns4:bold>Secondary analysis of 13,413 under-5 pneumonia cases in Malawi. Pneumonia associated case fatality ratios (CFR) were calculated by disease severity under the assumptions of the 2005 and 2014 WHO Integrated Management of Childhood Illness (IMCI) guidelines, with and without pulse oximetry. We investigated if pulse oximetry readings were missing not at random (MNAR).</ns4:p><ns4:p> <ns4:bold>Results: </ns4:bold>The CFR of patients classified as having non-severe pneumonia per the 2014 IMCI guidelines doubled under the assumption that pulse oximetry was not available (1.5% without pulse oximetry vs 0.7% with pulse oximetry, P<0.001). When 2014 IMCI guidelines were applied with pulse oximetry and a SpO<ns4:sub>2</ns4:sub> < 90% as the threshold for referral and/or admission, the number of cases meeting hospitalization criteria decreased by 70.3%. Unrecorded pulse oximetry readings were MNAR with an adjusted odds for mortality of 4.9 (3.8, 6.3), similar to that of a SpO<ns4:sub>2</ns4:sub> < 90%. Although fewer girls were hospitalized, female sex was an independent mortality risk factor.</ns4:p><ns4:p> <ns4:bold>Conclusions: </ns4:bold>In Malawi, implementation of the 2014 WHO IMCI pneumonia guidelines, without pulse oximetry, will miss high risk cases. Alternatively, implementation of pulse oximetry may result in a large reduction in hospitalization rates without significantly increasing non-severe pneumonia associated CFR if the inability to obtain a pulse oximetry reading is considered a WHO danger sign.</ns4:p>" @default.
