The delivery of prevention programmes for cardiovascular disease and chronic obstructive pulmonary disease in Lodz by primary care physicians

Primary prevention in general practice - views of German general practitioners: a mixed-methods study

Background

Policy efforts focus on a reorientation of health care systems towards primary prevention. To guide such efforts, we analyzed the role of primary prevention in general practice and general practitioners’ (GPs) attitudes toward primary prevention.

Methods

Mixed-method study including a cross-sectional survey of all community-based GPs and focus groups in a sample of GPs who collaborated with the Institute of General Practice in Berlin, Germany in 2011. Of 1168 GPs 474 returned the mail survey. Fifteen GPs participated in focus group discussions. Survey and interview guidelines were developed and tested to assess and discuss beliefs, attitudes, and practices regarding primary prevention.

Results

Most respondents considered primary prevention within their realm of responsibility (70%). Primary prevention, especially physical activity, healthy eating, and smoking cessation, was part of the GPs’ health care recommendations if they thought it was indicated. Still a quarter of survey respondents discussed reduction of alcohol consumption with their patients infrequently even when they thought it was indicated. Similarly 18% claimed that they discuss smoking cessation only sometimes. The focus groups revealed that GPs were concerned about the detrimental effects an uninvited health behavior suggestion could have on patients and were hesitant to take on the role of “health policing”. GPs saw primary prevention as the responsibility of multiple actors in a network of societal and municipal institutions.

Conclusions

The mixed-method study showed that primary prevention approaches such as lifestyle counseling is not well established in primary care. GPs used a selective approach to offer preventive advice based upon indication. GPs had a strong sense that a universal prevention approach carried the potential to destroy a good patient-physician relationship. Other approaches to public health may be warranted such as a multisectoral approach to population health. This type of restructuring of the health care sector may benefit patients who are unable to afford specific prevention programmes and who have competing demands that hinder their ability to focus on behavior change.

Evaluation of a tailored implementation strategy to improve the management of patients with chronic obstructive pulmonary disease in primary care: a study protocol of a cluster randomized trial

BACKGROUND

Chronic obstructive pulmonary disease (COPD) remains a major health problem, strongly related to smoking. Despite the publication of practice guidelines on prevention and treatment, not all patients with the disease receive the recommended healthcare, particularly with regard to smoking cessation advice where applicable. We have developed a tailored implementation strategy for enhancing general practitioners' adherence to the disease management guidelines. The primary aim of the study is to evaluate the effects of this tailored implementation intervention on general practitioners' adherence to guidelines.

METHODS/DESIGN

A pragmatic two-arm cluster randomized trial has been planned to compare care following the implementation of tailored interventions of four recommendations in COPD patients against usual care. The study will involve 18 general practices (9 in the intervention group and 9 in the control group) in Poland, each with at least 80 identified (at the baseline) patients with diagnosed COPD. The nine control practices will provide usual care without any interventions. Tailored interventions to implement four recommendations will be delivered in the remaining nine practices. At follow-up after nine months, data will be collected for all 18 general practices. The primary outcome measure is physicians' adherence to all four recommendations: brief anti-smoking advice, dyspnea assessment, care checklist utilization and demonstration to patients of correct inhaler use. This measurement will be based on data extracted from identified patients' records. Additionally, we will survey and interview patients with chronic obstructive pulmonary disease about the process of care.

DISCUSSION

The results of this trial will be directly applicable to primary care in Poland and add to the growing body of evidence on interventions to improve chronic illness care.

TRIAL REGISTRATION

This trial has been registered with Clinical Trials Protocol Registration System.

Resveratrol attenuates left ventricular remodeling in old rats with COPD induced by cigarette smoke exposure and LPS instillation

The objective of this study was to investigate left cardiac damage and the cardioprotective effects of resveratrol in old rats with COPD. Rats 22 months old were divided into three groups: control (CTL), smoking and lipopolysaccharides (SM/LPS), and SM/LPS plus resveratrol (SM/LPS-Res). Cardiac function, pathology, oxidative stress, and apoptosis index were measured. Expression of myocardial SIRT1 was studied by real-time quantitative polymerase chain reaction (PCR) and Western blot detection. The heart weight-body weight ratio (LVW/BW) increased in the SM/LPS group compared with the CTL group. Both the LVW/BW and the area of fibrosis in the SM/LPS-Res group decreased compared with those in the SM/LPS group. 8-OHdG expression increased in cardiac tissue of rats in the SM/LPS group, which could be inhibited by resveratrol. Resveratrol significantly increased the activity of superoxide dismutase (SOD) and reduced the cardiac malonyldialdehyde (MDA) level in the SM/LPS-Res group. There was a significant decrease in the extent of cardiomyocyte apoptosis in the SM/LPS-Res group compared with the SM/LPS group. SIRT1 mRNA increased in the SM/LPS-Res group compared with the SM/LPS group. In conclusion, resveratrol attenuated cardiac oxidative damage and left ventricular remodeling and enhanced the decreased expression of SIRT1 in hearts of old rats with emphysema and thus might be a therapeutic modality for cardiac injury complicated in chronic obstructive pulmonary disease (COPD).

Stimulating preventive procedures in primary care. Effect of PIUPOZ program on the delivery of preventive procedures

INTRODUCTION

Educational meetings are one of the most frequently used strategies to change doctors' professional behavior; however, their effectiveness as a single intervention is limited. This study evaluated the effect of a multifactorial intervention, based on interactive workshops, on the GPs' knowledge and the delivery rates of preventive procedures in primary care.

MATERIAL AND METHODS

The study population comprised 106 GPs working in the Wielkopolska region recruited to the PIUPOZ program (Improving Quality in Primary Care). The intervention in the program consisted of lectures, interactive workshops and an audit, before and three months after the training. Trained medical students directly observed GPs to register which of 12 studied preventive procedures were performed during the consultation in patients aged 40+.

RESULTS

A total of 1060 consultations were recorded, during which 4899 preventive procedures were delivered: 2115 before and 2784 after workshops. The mean number of preventive procedures per patient before and after workshops was 3.84 and 5.25 respectively (p < 0.0001). The most commonly performed preventive procedures were blood pressure, blood glucose and lipid profile measurement. Mean number of correct answers for 16 questions in the initial knowledge test was 8.7 and 12.7 in the final test (p < 0.0001).

CONCLUSIONS

The observed number of delivered preventive procedures was below the recommended range. Preventive procedures based on laboratory tests were performed more often than lifestyle counseling.
