Background: Detection of lifestyle risk factors by GPs is the first step required for intervention. Despite significant investment in preventive health care in general practice, little is known about whether GP detection of lifestyle risk factors have improved over time.Objectives: To examine whether sensitivity and specificity of GP detection of smoking, risky alcohol consumption and overweight and obesity has increased in patients presenting to see their GP, by comparing results from four Australian studies conducted between 1982 and 2011.Methods: Demographic characteristics of patient and GP samples and the prevalence, sensitivity and specificity of detection of each risk factor were extracted from published studies. Differences between GP and patient sample characteristics were examined. To identify trends over time in prevalence of risk factors, sensitivity and specificity of detection across studies and the Cochran-Armitage test for trend were calculated for each risk factor for the overall sample and by male and female subgroups.Results: There were no statistically significant changes in the sensitivity of GP detection of smoking or overweight or obesity over time. Specificity of detection of smoking increased from 64.7% to 98% (P < 0.0001) and decreased for overweight or obesity from 92% to 89% (P = 0.01). There was a small decrease in the sensitivity of detection of alcohol consumption (P = 0.02) and an increase in specificity (P = 0.01).Conclusions: Despite significant investment to increase GP detection and intervention for lifestyle risk factors, accurate detection of smoking, risky alcohol consumption and overweight and obesity occurs for less than two-thirds of all patients.

Background. People with a history of stroke or heart disease are at increased risk of future stroke; therefore, identification of risk factors by GPs is critical. Objectives. To compare the following among general practice patients with and without a history of stroke or heart disease: (i) self-reported prevalence rates of lifestyle risk factors; (ii) accuracy of GP detection of patient-reported risk factors and (iii) average proportion of patient-reported risk factors detected by GPs. Methods. Consecutive patients attending a participating general practice clinic were invited to participate in a cross-sectional touchscreen survey assessing lifestyle risk factors in 2010-11. The GP of each consenting patient completed a corresponding survey assessing the patient's risk factors. Demographic characteristics of patients and GPs were obtained. Results. Data from 51 GPs and 564 patients were analysed. Patients without a history of stroke or heart disease reported significantly higher rates of smoking (12%) and risky alcohol consumption (56%) than patients with a history of stroke or heart disease (6% and 36%, respectively). Low sensitivity of GP detection of risk factors was found for all risk factors for all patients. Patients with a history of stroke or heart disease have a significantly higher mean proportion of risk factors detected by their GP compared to patients without a history of stroke or heart disease (P = 0.00). Conclusion. Given low sensitivity and specificity of GP detection of risk factors among patients, alternate methods of identification are needed. Research is required to determine strategies to facilitate secondary care of patients with a history of stroke or heart disease by GPs. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was to explore the logistical and methodological strengths and weaknesses of some of the more common research designs which can be used to evaluate the impact of system- or population-level approaches for reducing alcohol-related harms. Method: This paper identifies studies that have evaluated system or population approaches to reduce alcohol-related harms. It highlights the tension caused by a desire for the most rigorous research designs, such as randomized controlled trials (RCTs), the most potentially efficacious interventions and the practical problems in applying the RCT to population-level research. Alternative research designs, which possess methodological rigour and are more feasible, are identified and described. The design with the strongest methodological characteristics and feasibility in allowing the evaluation of population interventions is considered to be the multiple baseline. Results: The multiple baseline design addresses potential problems of sample sizes, selection bias, the suitability and baseline stability of outcome measures, statistical analyses and the practicalities of conducting rigorous research in system- or population-level settings. Conclusion: The multiple baseline design has the capacity to allow methodologically and statistically stringent evaluations with relatively small sample sizes, low cost and fewer of the complications imposed by RCTs. Like all research designs it has limitations, but arguably represents the most practical and methodologically rigorous approach to the evaluation of system- or population-level strategies.

There is currently uncertainty regarding the relative performance of a retrospective diary (RD) and a quantity–frequency index (QFI) measure of weekly alcohol consumption. While some previous studies have found more consumption reported on an RD than a QFI, others have found the reverse. As yet, however, no study has compared computerized versions of these two measures. This cross-sectional study involved administration of a computerized survey in a community-based drug and alcohol treatment setting. Five hundred and eighty-six clients (420 males) attending counselling for a range of drug- and alcohol-related issues agreed to participate in the study. The major finding was that more alcohol consumption was reported on the RD, than on the QFI. Similarly, the RD detected a greater proportion of both heavy and high-risk drinkers than the QFI. It is argued that the RD may be preferable to the QFI as a measure of weekly alcohol consumption, for use in community-based treatment settings. [ABSTRACT FROM PUBLISHER]
