Nurse-led postdischarge telephone follow-up calls: A mixed study systematic review.

AIMS AND OBJECTIVES: To explore the quantitative and qualitative literature on the impact of nurse-led postdischarge telephone follow-up (TFU) call interventions on patient outcomes. BACKGROUND: Adverse patient outcomes such as postdischarge problems, premature contact with health systems, inability to self-manage conditions and hospital readmissions all have an impact on the health and well-being, and satisfaction of patients as well as a financial impact on healthcare systems. DESIGN: A mixed-study systematic review. REVIEW METHODS: A systematic search of CINAHL, Ebsco, PubMed, Quest and Cinch-Health databases was undertaken using the key terms "nurs*," "nurse-led," "nurse initiated," "discharge," "hospital," "telephone," "follow-up" and "telephone follow-up" to identify relevant original peer-reviewed studies published between 2010-2016. Ten articles were selected for inclusion. The selected papers were critically appraised. A sequential explanatory approach with a convergent synthesis was used to report findings following PRISMA guidelines. RESULTS: The findings demonstrate that nurse-led TFU interventions have the potential to improve patient outcomes. The studies suggest patient satisfaction with TFU is one of the strongest positive outcomes from the interventions. However, the results do not support improvement in patient readmission or mortality. CONCLUSIONS: Of the 10 studies reviewed, only two were methodologically strong limiting the conclusions that can be drawn from the current research on this topic. Telephone follow-up interventions improve patient satisfaction and have the potential to meet patient information and communication needs, improve self-management and follow-up appointment attendance and reduce postdischarge problems. Further research is required to explore patients' perceptions of the most useful content of TFU calls, the efficacy of TFU calls and nurses' perceptions and experiences of conducting TFU interventions. RELEVANCE TO CLINICAL PRACTICE: When conducted by a nurse, these interventions have the potential to enhance postdischarge care to patients and meet care needs. Patients perceive TFU as acceptable and are satisfied with this form of postdischarge care.

Sleep Disorders in Aboriginal and Torres Strait Islander People and Residents of Regional and Remote Australia.

STUDY OBJECTIVES: To compare the use of sleep diagnostic tests, the risks, and cofactors, and outcomes of the care of Indigenous and non-indigenous Australian adults in regional and remote Australia in whom sleep related breathing disorders have been diagnosed. METHODS: A retrospective cohort study of 200 adults; 100 Aboriginal and Torres Strait Islander and 100 non-indigenous adults with a confirmed sleep related breathing disorder diagnosed prior to September 2011 at Alice Springs Hospital and Cairns Hospital, Australia. RESULTS: Results showed overall Indigenous Australians were 1.8 times more likely to have a positive diagnostic sleep study performed compared with non-indigenous patients, 1.6 times less likely in central Australia and 3.4 times more likely in far north Queensland. All regional and remote residents accessed diagnostic sleep studies at a rate less than Australia overall (31/100,000/y (95% confidence interval, 21-44) compared with 575/100,000/y). CONCLUSION: The barriers to diagnosis and ongoing care are likely to relate to remote residence, lower health self-efficacy, the complex nature of the treatment tool, and environmental factors such as electricity and sleeping area. Indigeneity, remote residence, environmental factors, and low awareness of sleep health are likely to affect service accessibility and rate of use and capacity to enhance patient and family education and support following a diagnosis. A greater understanding of enablers and barriers to care and evaluation of interventions to address these are required. COMMENTARY: A commentary on this article appears in this issue on page 1255.

Obstructive sleep apnoea in adult indigenous populations in high-income countries: an integrative review.

BACKGROUND: Obstructive sleep apnoea is recognised as a common but under-diagnosed health issue. Currently, there is very little published data relating to the burden and impact of obstructive sleep apnoea among indigenous populations. The purpose of this review was to investigate the prevalence, impact, risk factors and treatment of obstructive sleep apnoea in indigenous populations in high-income countries. METHODS: An integrative review was conducted on 25 English language studies and reports that investigated obstructive sleep apnoea among indigenous populations in high-income countries. Studies that did not focus on indigenous populations in the results or discussion were excluded. Eligible studies were identified by searching PubMed, Web of Science and Google Scholar databases and reference lists of eligible studies. Publication dates range from 1998 to 2012. RESULTS: Synthesis of studies indicates the prevalence of obstructive sleep apnoea is higher and severity is greater in indigenous populations compared with non-indigenous populations. Comparable risk factors for obstructive sleep apnoea were identified in indigenous and non-indigenous populations, with only three studies identifying ethnicity as an independent risk factor. CONCLUSIONS: Indigenous populations in high-income countries are subject to an overall greater prevalence of obstructive sleep apnoea that is also more severe. A higher prevalence of obesity, alcohol and tobacco use and comorbid medical conditions associated with low socioeconomic status rather than indigenous status per se appears to explain this disparity.

Responses of Aboriginal and Torres Strait Islander Primary Health-Care Services to Continuous Quality Improvement Initiatives.

BACKGROUND: Indigenous primary health-care (PHC) services participating in continuous quality improvement (CQI) cycles show varying patterns of performance over time. Understanding this variation is essential to scaling up and sustaining quality improvement initiatives. The aim of this study is to examine trends in quality of care for services participating in the ABCD National Research Partnership and describe patterns of change over time and examine health service characteristics associated with positive and negative trends in quality of care. SETTING AND PARTICIPANTS: PHC services providing care for Indigenous people in urban, rural, and remote northern Australia that had completed at least three annual audits of service delivery for at least one aspect of care (n = 73). METHODS/DESIGN: Longitudinal clinical audit data from use of four clinical audit tools (maternal health, child health, preventive health, Type 2 diabetes) between 2005 and 2013 were analyzed. Health center performance was classified into six patterns of change over time: consistent high improvement (positive), sustained high performance (positive), decline (negative), marked variability (negative), consistent low performance (negative), and no specific increase or decrease (neutral). Backwards stepwise multiple logistic regression analyses were used to examine the associations between health service characteristics and positive or negative trends in quality of care. RESULTS: Trends in quality of care varied widely between health services across the four audit tools. Regression analyses of health service characteristics revealed no consistent statistically significant associations of population size, remoteness, governance model, or accreditation status with positive or negative trends in quality of care. CONCLUSION: The variable trends in quality of care as reflected by CQI audit tools do not appear to be related to easily measurable health service characteristics. This points to the need for a deeper or more nuanced understanding of factors that moderate the effect of CQI on health service performance for the purpose of strengthening enablers and overcoming barriers to improvement.

Sleep disordered breathing and polysomnography in Australia: trends in provision from 2005 to 2012 and the impact of home-based diagnosis.

STUDY OBJECTIVES: To describe the growth of publicly funded polysomnography (PSG) in Australia since 2004 and to compare this with earlier growth. METHODS: Longitudinal census-level data stratified by jurisdiction were retrieved from the Medicare Australia online database. RESULTS: There has been a near doubling in provision of PSG since the introduction of publicly funded in-home PSG under the Australian national Medicare program available to all Australian citizens in 2008. Overall annual PSG rates have risen from 339 in 2005 to 608 in 2012 per 100,000. This growth has exceeded that of comparable diagnostic procedures and all Medicare services overall. Queensland remains the leading jurisdiction per 100,000 Medicare enrollees for accessing Medicare-funded PSG. CONCLUSION: The continued growth in publicly funded PSG provision in Australia is unlikely to abate. The disparity in Australia between the estimated prevalence of sleep disorders, particularly obstructive sleep apnea, and the number of people having PSGs would suggest there remain a large number of undiagnosed cases. Support for the development of appropriate diagnostic and screening algorithms will be key in ensuring sustainable, effective, efficient, and accessible PSG services.
