In-practice management versus quitline referral for enhancing smoking cessation in general practice: a cluster randomized trial

BACKGROUND AND OBJECTIVE GPs are an important source of smoking cessation advice. This research examined whether a model encouraging GP referral of patients who smoke to a specialist service would be acceptable and effective for increased smoking cessation when compared with a model of in-practice management. METHODS The study design was cluster randomized controlled trial. Practices were randomized to one of two interventions, at a rate of 1:2: (i) standard in-practice GP management or (ii) referral to a quitline service. The main outcome measures were sustained abstinence of >or=1 month duration at 3-month follow-up and >or=10 months duration at 12 months, using intention to treat analysis. RESULTS At 3-month follow-up, patients in the referral condition were twice as likely to report sustained abstinence than those in the in-practice condition [12.3% compared with 6.9%; odds ratio (OR) = 1.92 (95% confidence interval (CI) 1.17-3.13]. At 12-month follow-up, patients in the referral condition had nearly three times the odds of sustained abstinence [6.5% compared with 2.6%; OR = 2.86 (95% CI 0.94-8.71)]. The intervention effect was mediated by the amount of help received outside the practice. CONCLUSIONS This research provided evidence that GPs referring smokers to an evidence-based quitline service results in increased cessation. The benefit is largely due to patients in the referral condition receiving more external help than patients in the in-practice condition, as they received equivalent practice-based help. Where suitable services exist, we recommend that referral become the normative strategy for management of smoking cessation in general practice to complement any practice-based help provided.

Diabetes in rural towns: effectiveness of continuing education and feedback for healthcare providers in altering diabetes outcomes at a population level: protocol for a cluster randomised controlled trial.

BackgroundType 2 diabetes is one of the fastest growing chronic diseases internationally. The health complications associated with type 2 diabetes can be prevented, delayed, or improved via early diagnosis and effective management. This research aims to examine the impact of a primarily web-based educational intervention on the diabetes care provided by general practitioners (GPs) in rural areas, and subsequent patient outcomes. A population-level approach to outcome assessment is used, via whole-town de-identified pathology records.Methods/designThe study uses a cluster randomised controlled trial with rural communities as the unit of analysis. Towns from four Australian states were selected and matched on factors including rurality, population size, proportion of the population who were Indigenous Australians, and socio-economic status. Eleven pairs of towns from two states were suitable for the trial, and one town from each pair was randomised to the experimental group. GPs in the towns allocated to the experimental group are offered an intervention package comprising education on best practice diabetes care via an on-line active learning module, a moderated discussion forum, access to targeted and specialist advice through an on-line request form, and town-based performance feedback on diabetes monitoring and outcomes. The package is offered via repeated direct mail.DiscussionThe benefits of the outcomes of the trial are described along with the challenges and limitations associated with the methodology.Trial registrationAustralian New Zealand Clinical Trials Registry: ACTRN12611000553976

Simplifying screening for osteoporosis in Australian primary care: the Prospective Screening for Osteoporosis; Australian Primary Care Evaluation of Clinical Tests (PROSPECT) study.

Objective:Although bone density by dual-energy x-ray absorptiometry (DXA) is the standard measure for the diagnosis of osteoporosis, as a screening tool, it has significant cost and availability of DXA is not universal. Prospective Screening for Osteoporosis; Australian Primary Care Evaluation of Clinical Tests (PROSPECT) was a national study undertaken to establish an effective prescreening protocol to be used in primary care facilitating targeted radiological investigation for osteoporosis in older women. Methods:Two hundred sixty-seven primary care physicians recruited 2,466 women 70 years and older who had no previous diagnosis of osteoporosis in a community-based cross-sectional study. The main outcome measures used were lumbar spine and femoral neck T-scores on DXA and presence of a vertebral fracture on thoracolumbar x-ray. Participant characteristics, gap-on-wall occiput test, and rib-to-pelvis distance measurements were provided by each primary care physician. Results:Of the study population, 21.8% (95% CI, 19.9%-23.8%) had osteoporosis of the femoral neck and/or lumbar spine based on DXA, and 24.7% (95% CI, 22.5%-26.9%) had at least one vertebral fracture. Only 7.3% (95% CI, 6.2%-8.3%) had both osteoporosis and radiological vertebral fracture. Univariate and multivariate regression modeling of the demographic and clinical data collected resulted in a three-factor predictive tool for the diagnosis of osteoporosis and/or vertebral fracture that included the following variables: rib-pelvis distance greater than 2 fingerbreadths (yes/no), ever use of estrogen for more than 6 months (yes/no), and body mass index (<25, 25-30, >30 kg/m2). Only screening women classified as moderate to high risk by the tool DXA plus plain x-ray would then result in 14% of women 70 years or older who were not being screened, with 93% of cases being detected. Conclusions:The Prospective Screening for Osteoporosis; Australian Primary Care Evaluation of Clinical Tests tool will contribute to the diagnosis and management of osteoporosis by facilitating targeted screening and hence reducing the need for unnecessary radiology tests at the primary care level.

Poor uptake of an online intervention in a cluster randomised controlled trial of online diabetes education for rural general practitioners

BackgroundIn Australia, rural and remote communities have high rates of diabetes-related death and hospitalisation. General practitioners (GPs) play a major role in diabetes detection and management. Education of GPs could optimise diabetes management and improve patient outcomes at a population level. The study aimed to describe the uptake of a continuing medical education intervention for rural GPs and its impact on the viability of a cluster randomised controlled trial of the effects of continuing medical education on whole-town diabetes monitoring and control.MethodTrial design: the cluster randomised controlled trial involved towns as the unit of allocation and analysis with outcomes assessed by de-identified pathology data (not reported here). The intervention programme consisted of an online active learning module, direct electronic access to specialist advice and performance feedback. Multiple rounds of invitation were used to engage GPs with the online intervention content. Evidence-based strategies (e.g. pre-notification, rewards, incentives) were incorporated into the invitations to enrol in the programme. Recruitment to the programme was electronically monitored through the hosting software package during the study intervention period.ResultsEleven matched pairs of towns were included in the study. There were 146 GPs in the 11 intervention towns, of whom 34 (23.3%) enrolled in the programme, and 8 (5.5%) completed the online learning module. No town had more than 10% of the resident GPs complete the learning module. There were no contacts made by GPs regarding requests for specialist advice. Consequently, the trial was discontinued.ConclusionThere is an ongoing need to engage primary care physicians in improving diabetes monitoring and management in rural areas. Online training options, while notionally attractive and accessible, are not likely to have high levels of uptake, even when evidence-based recruitment strategies are implemented.Trial registrationAustralian New Zealand Clinical Trials Registry, identifier: ACTRN12611000553976.

Patterns of type 2 diabetes monitoring in rural towns: How does frequency of HbA1c and lipid testing compare with existing guidelines?

OBJECTIVE To indicate levels of monitoring of type 2 diabetes in rural and regional Australia by examining patterns of glycated haemoglobin (HbA1c) and blood lipid testing. DESIGN AND SETTING Retrospective analysis of pathology services data from twenty regional and rural towns in eastern Australia over 24 months. PARTICIPANTS Of 13 105 individuals who had either a single HbA1c result ≥7.0% (53 mmol mol-1 ); or two or more HbA1c tests within the study period. MAIN OUTCOME MEASURES Frequency of testing of HbA1c and blood lipids (cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and triglycerides) were compared with guideline recommendations. RESULTS About 58.3% of patients did not have the recommended 6-monthly HbA1c tests and 30.6% did not have annual lipid testing. For those who did not receive tests at the recommended interval, the mean between-test interval was 10.5 months (95% CI = 7.5-13.5) rather than 6 months for HbA1c testing; and 15.7 (95% CI = 13.3-18.1) months rather than annually for blood lipids. For those with at least one out-of-range test result, 77% of patients failed to receive a follow-up HbA1c test and 86.5% failed to receive a follow-up blood lipid test within the recommended 3 months. Patients less than 50 years of age, living in a more remote area and with poor diabetes control were less likely to have testing at the recommended intervals (P < 0.0001). CONCLUSIONS Although poor diabetes testing is not limited to rural areas, more intensive diabetes monitoring is likely to be needed for patients living in non-metropolitan areas, particularly for some subgroups.

Comparison of plain vertebral X-ray and dual-energy X-ray absorptiometry for the identification of older women for fracture prevention in primary care

Recently, the dual‐energy X‐ray absorptiometry (DXA) diagnostic cut‐off (T‐score) for Australian Pharmaceutical Benefits Scheme (PBS) supported primary fracture prevention therapy with alendronate for older women (>70 years) has been changed from −3.0 to −2.5.

Utility of learning plans in general practice vocational training: a mixed-methods national study of registrar, supervisor, and educator perspectives.

BackgroundLearning plans are a compulsory component of the training and assessment requirements of general practice (GP) registrars in Australia. There is a small but growing number of studies reporting that learning plans are not well accepted or utilised in general practice training. There is a lack of research examining this apparent contradiction. The aim of this study was to examine use and perceived utility of formal learning plans in GP vocational training.MethodsThis mixed-method Australian national research project utilised online learning plan usage data from 208 GP registrars and semi-structured focus groups and telephone interviews with 35 GP registrars, 12 recently fellowed GPs, 16 supervisors and 17 medical educators across three Regional Training Providers (RTPs). Qualitative data were analysed thematically using template analysis.ResultsLearning plans were used mostly as a log of activities rather than as a planning tool. Most learning needs were entered and ticked off as complete on the same day. Learning plans were perceived as having little value for registrars in their journey to becoming a competent GP, and as a bureaucratic hurdle serving as a distraction rather than an aid to learning. The process of learning planning was valued more so than the documentation of learning planning.ConclusionsThis study provides creditable evidence that mandated learning plans are broadly considered by users to be a bureaucratic impediment with little value as a learning tool. It is more important to support registrars in planning their learning than to enforce documentation of this process in a learning plan. If learning planning is to be an assessed competence, methods of assessment other than the submission of a formal learning plan should be explored.

The impact of a GP clinical audit on the provision of smoking cessation advice

AimTo investigate whether participation in a clinical audit and education session would improve GP management of patients who smoke.MethodsGPs who participated in an associated smoking cessation research program were invited to complete a three-stage clinical audit. This process included a retrospective self-audit of smoking cessation management practices over the 6 months prior to commencing the study, attending a 2.5 hour education session about GP management of smoking cessation, and completion of a second retrospective self-audit 6 months later. Twenty-eight GPs completed the full audit and education process, providing information about their smoking cessation management with 1114 patients. The main outcome measure was changes in GP management of smoking cessation with patients across the audit period, as measured by the clinical audit tool.ResultsThe majority of GPs (57%) indicated that as a result of the audit process they had altered their approach to the management of patients who smoke. Quantitative analyses confirmed significant increases in various forms of evidence-based smoking cessation management practices to assist patients to quit, or maintain quitting across the audit period. However comparative analyses of patient data challenged these findings, suggesting that the clinical audit process had less impact on GP practice than suggested in GPs self-reported audit data.ConclusionThis study provides some support for the combined use of self-auditing, feedback and education to improve GP management of smoking cessation. However further research is warranted to examine GP- and patient-based reports of outcomes from clinical audit and other educational interventions.
