Tuberculosis Mortalities Among In-patients at a Tertiary Hospital in Zambia Between 2018 and 2019 - The Spectrum of Clinical Presentations

Abstract

ABSTRACTTuberculosis (TB) has remained one of the most important public health diseases and a leading cause of mortality from a single infectious agent in the world. In-patient mortalities have remained relatively high despite massive investment towards TB elimination. This prompted us to undertake a TB mortality review aimed at understanding the spectrum of clinical presentations in TB mortalities among in-patients in a local hospital set up in Zambia.Files of 74 in-patient TB related mortalities that had occurred at Kitwe Teaching Hospital over a 12-month period between June 2018 and June 2019 were audited using a structured questionnaire. The descriptive data was analyzed using SPSS v 16.0 statistical software and Microsoft excel 2016.The audit revealed that 50 (67.6%) of the files were for male patients with a mean age of 39.2 ± 11.6 years. 60(80%) were HIV positive, 60(80%) resided in high-density residential areas. On presentation to hospital, the commonest symptoms included productive cough and fever [31(41.9%) and 30(40.5%) respectively]. HIV positive male patients were presenting in hyperdynamic state (mean pulse rate of 117.2 ± 32.4 per min). Other findings included signs of multi-organ involvement [hypoalbuminemia 9(12.2%), deranged renal function 8(10.8%) and deranged liver enzymes 9(12.2%)] before mortality occurred.The spectrum of clinical presentations among in-patients with TB in a tertiary hospital include the following; male gender, age younger than 50 years, being HIV positive, residing in a high-density residential area and presenting with unstable hemodynamics. There is a need to focus strategies targeted at strengthening early recognition of clinical instability among admitted TB patients for at-risk populations, including young to middle aged males who are HIV positive.
