Impact of an integrated diabetes service involving specialist outreach and primary health care on risk factors for micro‐ and macrovascular diabetes complications in remote Indigenous communities in Australia

Interventions to improve primary healthcare in rural settings: A scoping review

BACKGROUND

Residents of rural areas have poorer health status, less healthy behaviours and higher mortality than urban dwellers, issues which are commonly addressed in primary care. Strengthening primary care may be an important tool to improve the health status of rural populations.

OBJECTIVE

Synthesize and categorize studies that examine interventions to improve rural primary care.

ELIGIBILITY CRITERIA

Experimental or observational studies published between January 1, 1996 and December 2022 that include an historical or concurrent control comparison.

SOURCES OF EVIDENCE

Pubmed, CINAHL, Cochrane Library, Embase.

CHARTING METHODS

We extracted and charted data by broad category (quality, access and efficiency), study design, country of origin, publication year, aim, health condition and type of intervention studied. We assigned multiple categories to a study where relevant.

RESULTS

372 papers met our inclusion criteria, divided among quality (82%), access (20%) and efficiency (13%) categories. A majority of papers were completed in the USA (40%), Australia (15%), China (7%) or Canada (6%). 35 (9%) papers came from countries in Africa. The most common study design was an uncontrolled before-and-after comparison (32%) and only 24% of studies used randomized designs. The number of publications each year has increased markedly over the study period from 1-2/year in 1997-99 to a peak of 49 papers in 2017.

CONCLUSIONS

Despite substantial inequity in health outcomes associated with rural living, very little attention is paid to rural primary care in the scientific literature. Very few studies of rural primary care use randomized designs.

Exploring the Reported Strengths and Limitations of Aboriginal and Torres Strait Islander Health Research: A Narrative Review of Intervention Studies

High quality intervention research is needed to inform evidence-based practice and policy for Aboriginal and Torres Strait Islander communities. We searched for studies published from 2008-2020 in the PubMed database. A narrative review of intervention literature was conducted, where we identified researcher reported strengths and limitations of their research practice. A total of 240 studies met inclusion criteria which were categorised as evaluations, trials, pilot interventions or implementation studies. Reported strengths included community engagement and partnerships; sample qualities; Aboriginal and Torres Strait Islander involvement in research; culturally appropriate and safe research practice; capacity building efforts; providing resources or reducing costs for services and communities; understanding local culture and context; and appropriate timelines for completion. Reported limitations included difficulties achieving the target sample size; inadequate time; insufficient funding and resources; limited capacity of health workers and services; and inadequate community involvement and communication issues. This review highlights that community consultation and leadership coupled with appropriate time and funding, enables Aboriginal and Torres Strait Islander health intervention research to be conducted. These factors can enable effective intervention research, and consequently can help improve health and wellbeing outcomes for Aboriginal and Torres Strait Islander people.

Improved metabolic parameters of people with diabetes attending an aboriginal health service in regional victoria

AIMS

To evaluate the baseline metabolic parameters and presence of diabetes complications in people with type 2 diabetes attending Rumbalara Aboriginal Co-operative in 2017 and compare it with other Aboriginal and Torres Strait Islander studies and Australian specialist diabetes services.

METHODS

Clinical and biochemical characteristics were determined, including diabetes type, age, weight, body mass index (BMI), blood pressure, micro- and macrovascular complications, glycosylated haemoglobin (HbA1c), haemoglobin, renal function, lipid profile, urine albumin:creatinine ratio, diabetes medications, renin angiotensin system inhibition therapies, HMG-CoA reductase inhibitors, and antiplatelet agents.

RESULTS

126 individuals had diabetes, 121 had type 2 diabetes. 113 identified as Aboriginal and/or Torres Strait Islander. Median age was 57.5 (48 - 68) years, median HbA1c was 7.8% (6.8 - 9.6), and median BMI 33.4kg/m² (29 - 42.3). Compared to other Australian Aboriginal and Torres Strait Islander populations, this population was older, had more obesity but with better glycaemia management. Compared to specialist diabetes services, this population was of similar age, with greater BMI but comparable HbA1c.

CONCLUSIONS

Aboriginal people living with type 2 diabetes attending this regional Aboriginal health service have comparable glycaemic management to specialist diabetes services in Australia, managed largely by primary care physicians with limited access to specialist care for the last five years.

Nurse-led vascular risk assessment in a regional Victorian Indigenous primary care diabetes clinic: An integrated Diabetes Education and Eye disease Screening [iDEES] study

AIM

The aim was to describe vascular risk factors in Australian adults with diabetes attending an Indigenous primary care nurse-led diabetes clinic.

DESIGN

This was a cross-sectional descriptive single-site study.

METHODS

Vascular risk factor data were extracted from the electronic health records of participants in the nurse-led integrated Diabetes Education and Eye disease Screening (iDEES) study at a regional Victorian Indigenous primary health-care clinic between January 2018 and March 2020.

RESULTS

Of 172 eligible adults, 135 (79%) provided data. Median (IQR) age was 56 (46-67) years; 89% were Indigenous; 95% had Type 2 diabetes of median (IQR) duration of 6 (2-12) years and 48 (36%) were male. Median HbA1c, blood pressure, cholesterol (total; LDL and HDL), triglycerides, eGFR, CRP and BMI were 8.0% (64 mmol/mol), 127/78 mm Hg, 4.2; 1.9; 1.1 mmol/L, 2.3 mmol/L, 89 ml/min/1.73 m² , 7.0 mg/L and 32.4 kg/m² . Of nine clinical risk factors, the median (IQR) number of risk factors at target was 4 (3-5) for women and 3 (2-5) for men, p_χ2  = 0.563. Clinical targets for BMI, HbA1c, blood pressure, triglycerides, total cholesterol, LDL cholesterol, urine albumin: creatinine ratio, HDL cholesterol and smoking were met by 14%, 34%, 38%, 39%, 44%, 52%, 54%, 62% and 64%, respectively.

CONCLUSION

A nurse-led model of integrated clinical risk factor assessment and diabetes education identified suboptimal levels of clinical risk factor control for avoiding diabetes chronic complications amongst Australian adults with diabetes in an Indigenous primary care setting.

IMPACT

A nurse-led model of diabetes care integrating clinical risk factor assessment into a diabetes education service is achievable. Understanding by stakeholders, including people with diabetes, their clinicians and health services, of the importance of regular monitoring of risk factors impacting diabetes complications is important. The novel nurse-managed iDEES primary-care model of care can assist.

TRIAL REGISTRATION

This study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12618001204235).

Barriers and enablers to health service access amongst people with diabetes: An exploration of the perceptions of health care staff in regional Australia

Healthcare staff are in a unique position of understanding client experiences, physiological impacts of client behaviour, the local healthcare system and the physical environment in which the services operate. Their perspectives may provide insights into the feasibility and effectiveness of existing models of diabetes care and suggestions for improvements to models of care (MoC). The objective of this qualitative study was to explore the experiences of healthcare staff delivering care for people with diabetes at the request of an existing healthcare service. Semi-structured interviews were conducted with 21 healthcare staff from three community health centres in one region of Victoria, Australia, in 2018. Interviews were audio-recorded and transcribed verbatim. Data were subject to qualitative content analysis and, subsequently, emerging themes were classified at individual, relationship, community and societal levels of the social-ecological model (SEM). Perceived barriers of access to health services using the current MoC included a lack of public transport, low socioeconomic status, job insecurity (resulting in an inability to take time away from work) and inflexible appointment times, all of which negatively impact diabetes management. Perceived enablers included having a co-located, multidisciplinary team, a holistic approach to diabetes management and motivation resulting from improvement in diabetes-related health outcomes. The findings indicate that there is potential to improve the service in this region by adopting a more integrated, team-focused and accessible MoC.

Progress and challenges for advanced practice nursing in Mexico and the United Kingdom

AIM

The aim of this study is to compare the advanced practice nursing development in Mexico with the United Kingdom.

BACKGROUND

In spite of the involvement of global and local bodies to establish and develop advanced practice nursing worldwide, progress remains variable due to the lack of homogeneity in health care systems and policies.

EVALUATION

Using thematic analysis from interviews of 29 health care professionals in Mexico, we identified four major issues that impact on the development of advanced practice nursing: (a) workforce, (b) organizational and institutional, (c) regulatory and legal and (d) academic and educational.

KEY ISSUES

Learning from the UK experience in relation to overcoming some of these issues has been insightful in terms of how advanced practice nursing skills in Mexican nurses can be developed.

CONCLUSIONS

Mexico is still in early stages of the development of APN. Based on the UK experience, the government may have to move forward to support higher level training, create labour market positions, establish new nursing functions, promote task-shifting and particularly implement solid regulation.

IMPLICATIONS FOR NURSING MANAGEMENT

The development of advanced practice nursing represents important challenges for training and practice of nursing in Mexico and the United Kingdom; therefore, interested actors will have to reach key agreements that could work as the foundations of an assertive planning process.

Feasibility of once weekly exenatide-LAR and enhanced diabetes care in Indigenous Australians with type 2 diabetes. (Long-acting-Once-Weekly-Exenatide laR-SUGAR, "Lower SUGAR" study)

AIMS

To assess the feasibility and metabolic effects of once weekly supervised injection of exenatide-LAR in addition to standard care in Indigenous Australians with type 2 diabetes.

METHODS

Two communities in Central Australia with longstanding specialist clinical outreach services were allocated by random coin toss to receive once-weekly exenatide-LAR injection with weekly nurse review and adjustment of medication for 20 weeks (community with exenatide-LAR) or to weekly nurse review in addition to standard care over 20 weeks (community without exenatide-LAR). The primary outcome was the feasibility of the intensive diabetes management model of care with and without weekly supervised exenatide-LAR. Secondary outcomes included change in HbA1c.

RESULTS

13 participants from community with exenatide-LAR and 9 participants from the community without exenatide-LAR were analysed. 85% of individuals in the community with exenatide-LAR and 67% in the community without exenatide-LAR attended more than half of clinic visits. Median difference in the change in HbA1c from baseline to final visit, adjusted for baseline HbA1c, between the community with exenatide-LAR and the community without exenatide-LAR was -3.1%, 95% CI (-5.80%, -0.38%; p = 0.03).

CONCLUSIONS

Weekly exenatide-LAR combined with weekly nurse review demonstrated greater improvements in HbA1c, highlighting its potential for use in remote communities. This article is protected by copyright. All rights reserved.

Effectiveness of a locality-based integrated diabetes care service on clinical outcomes

AIMS

To evaluate the effectiveness of a new locality-based integrated diabetes care service for people with Type 2 diabetes in an inner regional area.

METHODS

A quasi-experimental evaluation comparing baseline and follow up clinical data collected from general practices and specialist services participating in an integrated diabetes care programme in an inner-regional area. Patients had at least one specialist service consultation. The primary outcome was glycated haemoglobin (HbA1c).

RESULTS

Clinical data were collected for 178/239 patients (74.5% participation; aged 65± 11(SD) years, 46% female; median [interquartile range (IQR)] diabetes duration 19 (11.0-24.0) years from seven general practices over 33 months (median 18.5 months). There were reductions in HbA1c -0.7±1.6 % (8±18 mmol/mol) (p<0.001), systolic blood pressure -5.8±19.5 mmHg (p<0.001), diastolic blood pressure -2.4±14.3 mmHg (p=0.04), total cholesterol -0.5±1.3 mmol/l (p<0.001), low-density lipoprotein (LDL) -0.4±0.9 mmol/l (p<0.001), Body Mass Index -0.5±1.6 kg/m² (p<0.001), weight -1.8±4.7 kg (p<0.001). Urine albumin creatinine ratio [median (IQR)] at baseline was 3.0 mg/mmol (0.7-7) vs follow up 1.9 mg/mmol (0.8-5.5) p< 0.54).

CONCLUSIONS

Glycaemia and cardiovascular risk factors can be reduced in patients with long-standing Type 2 diabetes by moving to a locality based integrated primary-secondary care diabetes care service. This article is protected by copyright. All rights reserved.
