Impact of diabetes specialist nurses on inpatient care: A systematic review

Abstract

Background People with diabetes have longer hospital stays and poorer clinical outcomes. Diabetes inpatient specialist nurses have been introduced to improve care. Aims To assess the evidence for the benefit of diabetes specialist nurses in the inpatient setting. Methods A systematic search of MEDLINE (ovid), Embase (ovid), CINAHL (EBSCO) and Web of Science core collection from January 1998 to September 2019 was performed using key terms for diabetes specialist nurses and hospital setting. Studies measuring patient care using any standardised or validated outcome measures after introduction of a dedicated diabetes specialist nurse or nursing team were eligible for inclusion and findings reported by narrative synthesis. Results There were 10 studies which met the inclusion criteria. One was a randomised controlled study and the remaining nine studies were before and after studies with three of them using a time series analysis methodology. The majority reported length of stay (LOS) and showed a reduction in median LOS by between 0.5 and 3 days. Reductions in bed occupancy ranged from 39% to 47%. There was a paucity of evidence for outcomes related to patient care with some measures limited to single studies. These included a 52% reduction in total drug errors, improved patient knowledge, higher patient satisfaction and improved glycaemic control post‐discharge. There was no reduction of mortality observed. Conclusions These studies suggest a reduction in LOS and improved clinical care for patients with diabetes after the introduction of diabetes inpatient specialist nurses. Future research should examine a range of benefits associated with diabetes inpatient specialist nurse delivered services, including reduction of inpatient complications such as infections and cardiovascular events.

Tests on a scale for measuring the core competencies of paediatric specialist nurses: An exploratory quantitative study

“…Most current studies lacked tools targeted at assessing the core competencies of paediatric specialist nurses. The aim of this study was to establish a scientific and practical core competency evalu- which is consistent with the general characteristics of diabetes nurses (Akiboye et al, 2021) and ICU nurses (Guangli et al, 2017).…”

Development of Quality Measures for Inpatient Diabetes Care and Education Specialists: A Call to Action

“…Other quality outcomes associated with inpatient DCES practice include decreased cost of care, fewer after-hours calls, reduced in-hospital medication errors, and increased patient knowledge and satisfaction. 7,17,23,[27][28][29] Another important aspect reported in the literature relates to the various models of care used to achieve clinical and financial outcomes. Successful models are commonly led by interdisciplinary teams, which focus on glycemic management, diabetes care and education, and coordinated efforts to implement system-wide, evidenced-based practices.…”

A Narrative Review of Specialist Parkinson’s Nurses: Evolution, Evidence and Expectation

“…In the early 1980s, a rheumatology nurse specialist role was developed at Leeds General Infirmary to meet demands on the service and noting patients in trials preferred the frequent, longer appointments with the research nurses, compared to the short, infrequent reviews by their physician [7]. Nurse-led care is now embedded within multiple disease areas, including diabetes [8], multiple sclerosis [9] and chronic rheumatological conditions [10].…”
