Med (Anaesthesiology)--University of Limpopo(Medunsa Campus), 2010. / The purpose of this study was to interrogate the clinical relevance and cost effectiveness of the routine preoperative chest X-rays at DGMH. It was conducted as a descriptive cross-sectional prospective study of radiographic films in the Radiology department. A review of patients’ files and chest X-rays performed during a 6-month period from January to June 2008. Data from 100 patients’ files were included in the analysis. The age of patients ranged from 45 to 84years, the median age was 57years. The majority of patients younger than 50years were female, while the majority of male patients were over 50years. From a total of 100 patients only 8%(8 patients) were deemed unfit and consequently postponed or cancelled for further investigation and optimization. The cost for performing one routine chest X-ray was estimated to be R393 manpower, time and film inclusive, the total costs for the 100 patients included in this study being R39300. This study has provided some evidence that the routine preoperative chest X-rays can help in uncovering some abnormalities that were not apparent on clinical examination, it has pointed out that the impact of these uncovered abnormalities is very minimal on the planned surgery and that the costs associated with doing routine pre-operative chest X-rays can be substantial.

Yes / Lung cancer remains a major cause of preventable death and early diagnosis is critical to improving survival chances. The chest X-ray (CXR) remains the most common initial investigation, but clinical pathways need to support timely diagnosis through, where necessary, escalation of abnormal findings to ensure priority reporting and early CT scan. This single-centre study included a retrospective evaluation of a rapid lung cancer CXR pathway in its first year of operation (May 2018-April 2019). The pathway was initially designed for primary care referrals but could also be used for any CXR demonstrating abnormal findings. A parallel cross-sectional survey of radiographers explored their understanding, adherence and concerns regarding their role in the pathway operation. Primary care referrals on the rapid diagnostic pathway were low (n = 51/21,980; 0.2%), with 11 (21.6%) requiring a CT scan. A further 333 primary care CXR were escalated by the examining radiographer, with 100 (30.0%) undergoing a CT scan. Overall, 64 of the CT scans (57.7%) were abnormal or demonstrated suspicious findings warranting further investigation. There were 39 confirmed primary lung carcinomas, most with advanced disease. Survey responses showed that most radiographers were familiar with the pathway but some expressed concerns regarding their responsibilities and limited knowledge of CXR pathologies. This baseline evaluation of the rapid lung cancer pathway demonstrated poor referral rates from primary care and identified the need for improved engagement. Radiographer escalation of abnormal findings is an effective adjunct but underlines the need for appropriate awareness, training, and ongoing support. Engagement of the multiprofessional team is critical in new pathway implementation. Rapid diagnostic pathways can enable early diagnosis and the radiographer has a key role to play in their success.
