COVID-19 pandemic raises various challenges faced by health workers in hospitals. This study explored strategies for overcoming challenges in caring for COVID-19 patients at hospitals in Indonesia based on healthcare workers’ experience. In-depth interviews were employed with 28 healthcare workers (physicians and nurses) who were purposively sampled. Data were collected via phone and analysed using the Colaizzi method. Five following challenges were found: difficulties in working with personal protective equipment (PPE), offline training for handling Covid and using PPE not being implemented evenly for all health workers, physical and psychological fatigue, difficulties in carrying out health education and assessment towards patients and families, and limited resources to cope with the COVID-19 pandemic. Meanwhile, some barriers require support from the government, public and hospital managers. The information gained from research on the strategies for caring for COVID-19 patients can contribute to better preparedness for hospitals and health workers facing the COVID-19 pandemic.
Background
Where each patient has all three conduits of internal mammary artery (IMA), saphenous vein graft (SVG) and radial artery (RA), most confounders affecting comparison between conduits can be mitigated. Additionally, since SVG progressively fails over time, restricting patient angiography to the late period only can mitigate against early SVG patency that may have occluded in the late period.
Methods
Research protocol driven conventional angiography was performed for patients with at least one of each conduit of IMA, RA and SVG and a minimum of 7 years postoperative. The primary analysis was perfect patency and secondary analysis was overall patency including angiographic evidence of conduit lumen irregularity from conduit atheroma. Multivariable generalized linear mixed model (GLMM) was used. Patency excluded occluded or “string sign” conduits. Perfect patency was present in patent grafts if there was no lumen irregularity.
Results
Fifty patients underwent coronary angiography at overall duration postoperative 13.1 ± 2.9, and age 74.3 ± 7.0 years. Of 196 anastomoses, IMA 62, RA 77 and SVG 57. Most IMA were to the left anterior descending territory and most RA and SVG were to the circumflex and right coronary territories. Perfect patency RA 92.2% was not different to IMA 96.8%, P = 0.309; and both were significantly better than SVG 17.5%, P < 0.001. Patency RA 93.5% was also not different to IMA 96.8%, P = 0.169, and both arterial conduits were significantly higher than SVG 82.5%, P = 0.029. Grafting according to coronary territory was not significant for perfect patency, P = 0.997 and patency P = 0.289. Coronary stenosis predicted perfect patency for RA only, P = 0.030 and for patency, RA, P = 0.007, and SVG, P = 0.032.
When both arterial conduits were combined, perfect patency, P < 0.001, and patency, P = 0.017, were superior to SVG.
Conclusions
All but one patent internal mammary artery or radial artery grafts had perfect patency and had superior perfect patency and overall patency compared to saphenous vein grafts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
