Global Capnography Project (GCAP): implementation of capnography in Malawi - an international anaesthesia quality improvement project.

The Lancet Commission on Global Surgery emphasised the importance of access to safe anaesthesia care. Capnography is an essential monitor for safe anaesthesia, but is rarely available in low-income countries. The aim of this study was twofold: to measure the prevalence of capnography in the operating theatres and in intensive care units; and to determine whether its introduction was feasible and could improve the early recognition of critical airway incidents in a low-income country. This is the first project to do this. Forty capnographs were donated to eight hospitals in Malawi. Thirty-two anaesthesia providers received a 1-day capnography training course with pre- and post-course knowledge testing. Providers kept logbooks of capnography use and recorded their responses to abnormal readings. On follow-up at 6 months, providers completed questionnaires on any significant patient safety incidents identified using capnography. In January 2017, at the commencement of the project, only one operating theatre had a capnograph. Overall, 97% and 100% 'capnography gaps' were identified in the theatres and intensive care units, respectively. The mean (SD) scores of our capnography multiple choice questionnaires improved after training from 15.00 (3.16) to 18.70 (0.99), p = < 0.001. The capnography equipment was appropriately robust and performed well. Six months following implementation, 24 (77%) anaesthesia providers reported recognising 44 oesophageal intubations and 28 (90%) believed that capnography had saved lives. This study has shown it is feasible to introduce capnography in a low-income country, resulting in early recognition of critical airway incidents and ultimately helping to save lives. Building on the experience of the first trial of pulse oximetry implementation in low-income countries in 2007, we believe this is one of the most important projects in anaesthesia safety in the last decade.
