Evidence-practice gaps in lung cancer: A scoping review

Abstract

Lung cancer is a significant international health problem. Aligning clinical practice with evidence-based guideline recommendations has the potential to improve patient outcomes. This scoping review describes evidence-practice gaps across the diagnostic and management care pathway for lung cancer. We conducted searches of online databases Medline, PsychInfo, Cinahl and the Cochrane Library to identify studies published between 2008 and 2012. Of 614 articles screened, 65 met inclusion criteria. We identified seven evidence-practice gaps: (1) delays in timely diagnosis and referral; (2) curative and (3) palliative treatments are under-utilised; (4) older age and co-morbidities influence the use of treatments; (5) the benefits of multidisciplinary team review are not available to all lung cancer patients; (6) psychosocial needs are unmet; and (7) early referral to palliative care services is under-utilised. The scoping review highlighted three key messages: (1) there are significant challenges in the timely diagnosis and referral of lung cancer; (2) curative and palliative treatments, psychosocial support and palliative care are under-utilised in lung cancer management; and (3) variations in treatment utilisation appear to be associated with non-disease factors such as patient characteristics, provider practices and the organisation of health care services. Future research should focus on designing interventions to overcome variations in care.

“…Therapeutic advances can improve poor survival rates. It is, therefore, important patients with suspected lung cancer receive timely diagnosis and treatment, but there is marked heterogeneity in referral practice leading to avoidable delays [4].…”

Candida albicans Beta-Glucan Induce Anti- Cancer Activity of Mesenchymal Stem Cells against Lung Cancer Cell Line: An In-Vitro Experimental Study

“…Despite using conventional chemotherapy regimens and radiotherapy against cancer cells; because of emerging drug resistant stemness cells, relapses and metastasis, lung cancer treatment have been faced with many obstacles in many developed and developing countries of the world. To overcome these challenges in the treatment of lung cancer, use of natural compounds and supplements like beta-glucan has received much attention for their beneficial properties (Rankin et al, 2018).…”

“Yes, I have cancer, but I'm also lonely”; tackling a common problem in cancer care

“…Indeed, there are significant evidence gaps in many aspects of lung cancer early diagnosis and management. Rankin et al (2018) tackle "evidencepractice gaps" in lung cancer; there is disconnect between "best practice" and "actual practice" in many areas of health care-given the huge global burden of lung cancer, it is especially important to improve the evidence base, and encourage practice which is compliant with this evidence. Their review highlights challenges across the lung cancer journey-including timely diagnosis and referral, underutilisation of available treatments, psychosocial support and multidisciplinary team management.…”
