Systematic Review on Effectiveness of Patient/Nurse Navigation on Health Outcomes of Breast Cancer Patients

Abstract

Background: Continued advances in technology and cancer treatment have made cancer care more complex. A wide range of healthcare professionals are involved in the care and there is a potential for poor coordination and miscommunication. Hence there is a need to integrate and coordinate care to enhance quality care and improved health outcomes patient navigation approach was introduced by Dr Harold Freeman at Harlem Hospital Centre, the USA in 1990. Some literature identified nurses as a suitable candidate to assume this role. But there is a need to further explore the effectiveness of patient/nurse navigation program for its effectiveness on health outcomes such as anxiety, psychological distress, mood states, quality of life, symptom distress (nausea, vomiting, sleep disturbances) physical well being, psychological well being, coping, support and patient satisfaction. Aim: To synthesize the best available evidence on the effectiveness of patient/nurse navigation program in the care of women with breast cancer. Methods: This review was conducted according to Cochrane guidelines. An extensive literature search was conducted in PubMed, CINAHL, Proquest, Cochrane Library, IndMed (Indian database of studies) and Shodhganga, a reservoir of Indian theses from January 1990-January 2017 for relevant studies published in the English language. The search criteria were limited to randomized controlled trials with patient or nurse navigation interventions compared with routine/usual care interventions without patient/nurse navigator in women with diagnosis of breast cancer aged 18 years and above, at any stage of illness undergoing any treatment in a hospital setting, including inpatient and outpatient/ambulatory care and studies. Results: Out of 238 studies assessed for eligibility only 6 studies were assessed for methodological quality. Quality assessment was done by using Delphi checklist by two independent reviewers. The risks of bias in RCTs were assessed using Cochrane risk of bias tool. Due to the methodological heterogeneity of the studies, a meta-analysis was not performed. The reviewers categorized the main outcomes as quality of life, patient satisfaction with care, anxiety, psychological distress and physical problems and other outcomes (treatment adherence, barriers to care, diagnostic interval, timely access to care, time to completion of treatment, use of health care resources) and presented it in narrative form. Conclusion: This review provides evidence that navigation programs have some benefit on breast cancer patients' health outcomes. The findings from this review show that there are a limited number of studies reporting health outcomes of breast cancer patients from inpatient settings and especially no studies from Asian countries. This warrants the need for developing navigation programs in developing countries especially in Indian setting where no navigation programs are being reported in cancer care.
