Effect of a computer-guided, quality improvement program for cardiovascular disease risk management in primary health care: the treatment of cardiovascular risk using electronic decision support cluster-randomized trial

Background— Despite effective treatments to reduce cardiovascular disease risk, their translation into practice is limited. Methods and Results— Using a parallel arm cluster-randomized controlled trial in 60 Australian primary healthcare centers, we tested whether a multifaceted quality improvement intervention comprising computerized decision support, audit/feedback tools, and staff training improved (1) guideline-indicated risk factor measurements and (2) guideline-indicated medications for those at high cardiovascular disease risk. Centers had to use a compatible software system, and eligible patients were regular attendees (Aboriginal and Torres Strait Islander people aged ≥35 years and others aged ≥45 years). Patient-level analyses were conducted using generalized estimating equations to account for clustering. Median follow-up for 38 725 patients (mean age, 61.0 years; 42% men) was 17.5 months. Mean monthly staff support was <1 hour/site. For the coprimary outcomes, the intervention was associated with improved overall risk factor measurements (62.8% versus 53.4% risk ratio; 1.25; 95% confidence interval, 1.04–1.50; P=0.02), but there was no significant differences in recommended prescriptions for the high-risk cohort (n=10 308; 56.8% versus 51.2%; P=0.12). There were significant treatment escalations (new prescriptions or increased numbers of medicines) for antiplatelet (4.3% versus 2.7%; P=0.01), and BP lowering (18.2% versus 11.0%; P=0.02) but not lipid-lowering medications. Conclusions— In Australian primary healthcare settings, a computer-guided quality improvement intervention, requiring minimal support, improved cardiovascular disease risk measurement but did not increase prescription rates in the high-risk group. Computerized quality improvement tools offer an important, albeit partial, solution to improving primary healthcare system capacity for cardiovascular disease risk management.

Buckle up safely (Shoalhaven): a process and impact evaluation of a pragmatic, multifaceted preschool-based pilot program to increase correct use of age-appropriate child restraints

Objective: To conduct a process and impact evaluation of a multifaceted education-based pilot program targeting correct use of age-appropriate restraints in a regional setting with a high proportion of Aboriginal and Torres Strait Islander families. Methods: The program was delivered in 2010 in 3 early learning centers where 31 percent of the children were of Aboriginal and Torres Strait Islander descent. Each component of the program was assessed for message consistency and uptake. To measure program effectiveness, participating children were matched 1:1 by age, language spoken at home, and annual household income with 71 children from the control arm of a contemporaneous trial. The outcome measure in the control and program centers (a 4-category ordinal scale of restraint use) was compared using ordinal logistic regression accounting for age of the parent. Results: Process evaluation found that though program components were delivered with a consistency of message, uptake was affected by turnover of all staff at one center and by parents experiencing difficulty in paying for subsidized restraints at each of the centers. Impact evaluation found that children from the centers receiving the program had nearly twice the odds of being in a better restraint category than children matched from the control group (adjusted odds ratio [ORadj] = 2.06, 95% confidence interval [CI], 1.09–3.90). Conclusions: This was a pragmatic study reflecting the real-life issues of implementing a program in preschools where 57 percent of families had a low income and turnover of staff was high. Despite these issues, impact evaluation showed that the integrated educational program showed promise in increasing correct use of age-appropriate restraints. The findings from this pilot study support the use of an integrated educational program that includes access to subsidized restraints to promote best practice child restraint use among communities that include a high proportion of Aboriginal and Torres Strait Islander families in New South Wales. Future trials in similar settings should consider offering more support in centers with high turnover of staff and offering alternative methods of payment when families experience financial difficulties in purchasing the subsidized restraints. If proven in larger trials, this approach could reduce death and injuries in child passengers in this vulnerable group.

Gender inequalities in cardiovascular risk factor assessment and management in primary healthcare

Objectives To quantify contemporary differences in cardiovascular disease (CVD) risk factor assessment and management between women and men in Australian primary healthcare services. Methods Records of routinely attending patients were sampled from 60 Australian primary healthcare services in 2012 for the Treatment of Cardiovascular Risk using Electronic Decision Support study. Multivariable logistic regression models were used to compare the rate of CVD risk factor assessment and recommended medication prescriptions, by gender. Results Of 53 085 patients, 58% were female. Adjusting for demographic and clinical characteristics, women were less likely to have sufficient risk factors measured for CVD risk assessment (OR (95% CI): 0.88 (0.81 to 0.96)). Among 13 294 patients (47% women) in the CVD/high CVD risk subgroup, the adjusted odds of prescription of guideline-recommended medications were greater for women than men: 1.12 (1.01 to 1.23). However, there was heterogeneity by age (p <0.001), women in the CVD/high CVD risk subgroup aged 35–54 years were less likely to be prescribed the medications (0.63 (0.52 to 0.77)), and women in the CVD/high CVD risk subgroup aged ≥65 years were more likely to be prescribed the medications (1.34 (1.17 to 1.54)) than their male counterparts. Conclusions Women attending primary healthcare services in Australia were less likely than men to have risk factors measured and recorded such that absolute CVD risk can be assessed. For those with, or at high risk of, CVD, the prescription of appropriate preventive medications was more frequent in older women, but less frequent in younger women, compared with their male counterparts.

Overcoming barriers to use of child car seats in an urban Aboriginal community—formative evaluation of a program for Aboriginal Community Controlled Health Services

BackgroundLittle is known about the barriers to use of child car seats in Australian Aboriginal communities, or the acceptability of programs to increase appropriate car seat use. This formative evaluation sought to consult and partner with Aboriginal Community Controlled Health Services (ACCHS) to develop and evaluate the feasibility and acceptability of a program intended to improve optimal use of child car seats.MethodsFocus groups were conducted with parents and carers of Aboriginal children to identify the barriers and facilitating factors for child car seat use, and staff of two ACCHS were interviewed to inform program development. Following the implementation of the resulting multi-faceted program, consisting of staff training, education, hands-on demonstrations and a subsidised car seat distribution scheme, interviews were conducted to assess process issues and acceptability with 13 staff members.ResultsParents and carers in the focus groups reported a lack of awareness of child car seat use, confusion about the right car seats for different aged children but agreed about the importance of safety and community responsibility to keep children safe in cars. Interviews with service staff informed an approach to deliver relevant information. Information and resources were delivered to families, while the car seat distribution scheme supplied 33 families with child car seats. Following the conclusion of the program, staff reported that the program was relevant to their role. They also valued the car seat distribution scheme. Staff training in selection and installation of car seats increased confidence in staff knowledge.ConclusionsWe developed a program to promote child car seat use in ACCHS, which focused on developing capacity, made use of existing infrastructure and developed resources for use in this setting. The program shows promise as a means to promote child car seat use in Aboriginal communities; however, the impact on child car seat use will need to be evaluated in a larger scale prospective trial.

An Exploration of Underrepresentation of Aboriginal Cancer Patients Attending a Regional Radiotherapy Service in Western Australia

Travel logistics impede Aboriginal patients’ uptake of cancer treatments and is one reason for the poorer outcomes of Aboriginal people with cancer. This research examined benefits of a newly established rurally based radiotherapy unit in southwest Western Australia (WA), and included exploring the experience of Aboriginal patients and possible reasons for Aboriginal people’s underrepresentation in treatment. Semi-structured in-depth interviews with 21 service providers involved in the treatment and care of people with cancer, and 3 Aboriginal patients with cancer who undertook radiotherapy at the Service were undertaken. Data were subject to thematic analysis involving immersion in the data for familiarization, inductive coding, investigator discussion and refining of emerging themes and triangulation of patient and provider interviews. Aboriginal cancer patients were positive about the treatment and support they had received, highlighting the often complex challenges faced by rural Aboriginal cancer patients in accessing and maintaining treatment. Service providers offered suggestions for small numbers presenting to the Service, including late presentation, potential perceptions of cultural insensitivity on the part of service providers, out-of-pocket costs and under-ascertainment of Aboriginal status. The Service has put in place practices and initiatives to support patient health and wellbeing, including making the facility more welcoming towards Aboriginal people and ensuring culturally appropriate care.

Cancer support services: Are they meeting the needs of rural radiotherapy patients?

This paper examines the supportive care in place to meet the needs of patients receiving radiotherapy at a regional oncology service in Bunbury, Western Australia. Semi-structured in-depth interviews with 21 service providers and 17 adults diagnosed with cancer who underwent radiotherapy at the Service were recorded, transcribed and analysed thematically. Key themes relevant were co-operation and collaboration of interdisciplinary team members; support from organisations to assist with accommodation, transport, emotional support and provision of practical assistance, as well as barriers to accessing support. Most participants were positive about the support available, recognising the needs of rural radiotherapy patients for assistance with travel, accommodation and psychosocial support to help deal with the stressors they face. Collaboration between the various service providers maximised the support available to patients but the drop off in psychosocial support once the intensity of treatment was completed was identified as a weakness in the support available. The support system, established around a regional radiotherapy service, was enhanced by the collaborative professional relationships developed among service providers. The service extends beyond clinical service delivery by recognising financial, logistical and psychosocial support needs, factors to be considered to ensure rural radiotherapy patients are provided with holistic care.

“He’s the Number One Thing in My World”: Application of the PRECEDE-PROCEED Model to Explore Child Car Seat Use in a Regional Community in New South Wales

We explored the factors influencing the use of age-appropriate car seats in a community with a high proportion of Aboriginal families in regional New South Wales. We conducted a survey and three focus groups with parents of children aged 3–5 years enrolled at three early learning centres on the Australian south-east coast. Survey data were triangulated with qualitative data from focus groups and analysed using the PRECEDE-PROCEED conceptual framework. Of the 133 eligible families, 97 (73%) parents completed the survey including 31% of parents who reported their children were Aboriginal. Use of age-appropriate car seats was reported by 80 (83%) of the participants, and awareness of the child car seat legislation was high (91/97, 94%). Children aged 2–3 years were less likely reported to be restrained in an age-appropriate car seat than were older children aged 4–5 years (60% versus 95%: χ2 = 19.14, p < 0.001). Focus group participants highlighted how important their child’s safety was to them, spoke of the influence grandparents had on their use of child car seats and voiced mixed views on the value of authorised child car seat fitters. Future programs should include access to affordable car seats and target community members as well as parents with clear, consistent messages highlighting the safety benefits of using age-appropriate car seats.
