Do physicians assess lifestyle health risks during general medical examinations? A survey of general practitioners and obstetrician-gynecologists in Quebec

BACKGROUND: In Canada several guidelines have been published for the screening of lifestyle health risks during general medical examinations. The authors sought to examine the extent to which such screening practices have been integrated into medical practice, to measure physicians'' perceived level of difficulty in assessing these risks and to document physicians'' evaluation of their formal medical training in lifestyle risk assessment. METHODS: An anonymous mail survey was conducted in 1995 in Quebec with a stratified random sample of 1086 general practitioners (GPs) and with all 241 obstetrician-gynecologists (Ob-Gyns). The authors evaluated the proportion of physicians who reported routine assessment (with 90% or more of their patients) of substance use, family violence and sexual history during general medical examinations of adult and adolescent patients; the proportion of those who find inquiring about these issues difficult; and the proportion of those who evaluated their medical training in lifestyle risk assessment as adequate or excellent. RESULTS: The overall response rate was 72.6%. Among adult patients, 82.2% of the GPs reported routinely assessing tobacco use, 67.2% alcohol consumption, 34.2% illicit drug use and 3.2% family violence; the corresponding proportions for assessment among adolescent patients were 77.1%, 61.8%, 52.9% and 5.6%. Comparatively fewer Ob-Gyns reported routinely assessing these issues (56.1%, 28.6%, 20.4% and 1.3% respectively among adults and 62.7%, 35.2%, 26.8% and 2.8% respectively among adolescents). In the area of sexual history, condom use was routinely assessed by more Ob-Gyns than GPs (47.0% v. 28.2%); however, the proportion of Ob-Gyns and GPs was equally low for assessing number of partners (24.8% and 23.1%), sexual orientation (18.8% and 16.9%) and STD risk (26.2% and 21.2%). The vast majority of GPs and Ob-Gyns reported finding it difficult to assess family violence (86.5% and 93.0%) and sexual abuse (92.7% and 92.4% respectively). Over 80% of the physicians felt that they had had adequate or excellent medical training in assessing risk behaviours for heart disease and STD risk. The proportion who felt this way about their training in screening for illicit drug use, family violence and sexual abuse ranged between 12.7% and 31.6%. INTERPRETATION: Although morbidity and mortality associated with smoking, alcohol consumption, illicit drug use, unsafe sexual practices, family violence and sexual abuse have been well documented, routine screening for these risk factors during general medical examinations has yet to be integrated into medical practice.     

District programme to reduce smoking: effect of clinic supported brief intervention by general practitioners.

By encouraging and supporting general practitioners to undertake brief intervention on a routine basis smokers'' clinics could reach many more smokers than are willing to attend for intensive treatment. In a study with 101 general practitioners from 27 practices 4445 cigarette smokers received brief intervention with the support of a smokers'' clinic, brief intervention without such support, or the general practitioners'' usual care. At one year follow up the numbers of smokers who reported that they were no longer smoking cigarettes were 51 (13%), 63 (9%), and 263 (8%), respectively (p less than 0.005). After an adjustment was made for those cases not validated by urine cotinine concentrations the respective success rates were 8%, 5%, and 5%. Use of nicotine chewing gum was associated with higher self reported success rates. General practitioners providing supported brief intervention encouraged not only more smokers to use the gum but also more effective use; gum users in this group reported a success rate of 27% at one year. Compliance by the general practitioners in recording smoking state averaged 45%, and significantly higher success rates were reported by patients whose smoking state had been recorded. Brief intervention by general practitioners with the support of a smokers'' clinic thus significantly enhanced success rates based on self reports. Better results might be obtained if general practitioners'' compliance with the procedure could be improved and if they encouraged more of their patients to try nicotine gum. Collaboration of this kind between a smokers'' clinic and local general practitioners could deliver effective help to many more smokers than are likely to be affected if the two continue to work separately.     

Public health: Youth substance use and abuse: challenges and strategies for identification and intervention

Public health initiatives to distribute nicotine replacement therapy free of charge as a means of promoting smoking cessation are ongoing. Are there enough smokers interested in using nicotine replacement therapy to have a substantial impact on the prevalence of smoking if this aid were distributed free to all interested smokers? We conducted a telephone survey of 825 randomly selected daily smokers aged 18 years or older who had smoked at least 10 cigarettes per day at some point in their lives. Overall, 58.9% of the respondents said they would be interested in nicotine replacement therapy if it were offered for free. Of those interested, almost all (93.8%) said that they would use the nicotine replacement therapy to help them quit for good. There were differences in the levels of interest: smokers who intended to quit were more interested in using the nicotine replacement therapy than those who planned to reduce or maintain their smoking.Nicotine replacement therapy significantly increases a smoker''s chances of quitting.¹ It is widely available in Canada and can be obtained over the counter, usually at a cost to the consumer. Several public health initiatives have explored the advantages of free distribution of nicotine replacement therapy as a means of promoting smoking cessation.^2,3 Based on the popularity of these mass distribution efforts, it has been suggested that giving free nicotine replacement therapy to all interested smokers could have an important impact on the prevalence of smoking.²This statement assumes that a substantial proportion of smokers would actually be interested in receiving free nicotine replacement therapy and would use it in an attempt to quit. Previous studies^4,5 have reported a high level of interest among smokers; however, their results may reflect a response bias rather than a true intention to use nicotine replacement therapy. Health care professionals need to know how receptive smokers are to using nicotine replacement therapy. We sought to evaluate smokers'' attitudes by asking novel questions about their interest in receiving free nicotine replacement therapy and what they would do if they received it.     

Raynaud's phenomenon in forestry workers in Quebec.

A survey of 1540 forestry workers in Quebec found a prevalence of Raynaud''s phenomenon of 30.5% among chain-saw users and 8.7% among nonusers. Prevalence was related directly to duration of use of the chain-saw. The mean interval (+/- the standard deviation) between the time the chain-saw was first used and the onset of Raynaud''s phenomenon was 7.8 +/- 5.6 years. After 20 years of chain-saw use over 50% of the population had Raynaud''s phenomenon. Relative risks among those using a chain-saw for more than 10 years were 3.60 for nonsmokers and 6.55 for smokers. Other factors associated with the phenomenon included a family history of nonoccupational Raynaud''s phenomenon, previous injuries to the arms, climate and type of residence during the wood-cutting season. Decreased work capacity, interference with leisure activities and changes in professional orientation often resulted from this disease. These problems should be taken into account when disability compensation is being considered.     

Diversion programs for impaired physicians.

Nine states have legislated impaired physician programs administered by state medical boards (2), by independent agencies (4), or by medical societies through contracts with medical boards (3). All other state programs are administered by medical societies. California''s diversion program has been in effect for more than 10 years. It was the first program for alcohol- and drug-addicted physicians in the country administered by the state agency that also disciplines physicians. Of the physicians who enrolled in this program, 72% have completed it successfully. A total of 618 physicians have been accepted into the program since its inception, with 247 physicians currently participating.     

The Effect of “In Favor of Myself”: Preventive Program to Enhance Positive Self and Body Image among Adolescents

Background

Positive self-esteem, emotional well-being, school achievements and family connectedness are considered protective factors against health-compromising behaviors.This study examined the effect of an interactive, community-based, media literacy and dissonance wellness program, In Favor of Myself, on the self-image, body image, eating attitudes and behavior of young adolescents. A preliminary cohort study was conducted among 972 program participants who did not take part in the controlled trial. Over 75% of participants said they would recommend the program to their friends.

Methods

A controlled trial was conducted to evaluate program acceptability, efficacy and effectiveness among 259 participants (210 in the intervention group and 49 in the control group), aged 12–14 years, who completed questionnaires during at least two assessment times. Program materials were provided, along with leaders'' training, in order to ensure quality program delivery and creation of a wide network of committed program leaders.

Results

The program significantly reduced drive for thinness and self-worth contingent upon others'' approval, the gap between current body figure and ideal figure, and the impact of mood on girls'' self-image. Superiority was found among those participating in the intervention group with respect to recognizing media strategies, the influence of media on desire to change, and the influence of appearance on self-confidence and drive for thinness.

Conclusions

In Favor of Myself shows promising results for strengthening adolescents'' ability to cope with the challenges of their life stage. Suggestions for improving In Favor of Myself are presented.     

Efficacy of genotype notification to Japanese smokers on smoking cessation—An intervention study at workplace

Objectives: It is well-known that smoking causes many diseases including cancers. Informing smokers of their genotypes associated with the vulnerability to the harms of smoking may be effective measures for smoking cessation. The present study examined the effects of genotype notification of an oncogene (L-myc) genotype to smokers on their behavior to quit smoking. Methods: Subjects were 562 employees of a bank who answered to be a smoker for a questionnaire used at annual health checkup at workplace from July to December 2002. Those enrolled on August, October, and December were allocated into the genotype notification group (intervention group), and the rest into the controls. Among 286 smokers allocated into the intervention group, 257 participants (89.9%) agreed to genotype testing. One year after the enrollment, a follow-up questionnaire survey was conducted for all smokers including controls. Results: Those who stated to have quitted smoking were 22 (8.0%) among the 276 controls and 15 (5.8%) among the 257 genotype notified participants, providing that the odds ratio (OR) of cessation for the intervention was 0.64 (95% confidence interval, 0.32–1.28). No psychological problems associated with genotype notification were observed. Conclusion: The present study did not show positive effects of genotype notification on smoking cessation rate. To elevate the cessation rate, methods to explain and notify genotypes should be improved.     

Prevalence of hardcore smoking in England,and associated attitudes and beliefs: cross sectional study

Objective To quantify the prevalence and characteristics of hardcore smokers in England.Design Cross sectional survey.Setting Interview in respondents'' household.Participants 7766 adult cigarette smokers.Main outcome measures Hardcore smoking defined by four criteria (less than a day without cigarettes in the past five years; no attempt to quit in the past year; no desire to quit; no intention to quit), all of which had to be satisfied.Results Some 16% of all smokers were categorised as hardcore. Hardcore smoking was associated with nicotine dependence, socioeconomic deprivation, and age, rising from 5% in young adults aged 16-24 to 30% in those aged ≥ 65 years. Hardcore smokers displayed distinctive attitudes towards and beliefs about smoking. In particular they were likely to deny that smoking affected their health or would do so in the future. Prevalence of hardcore smoking was almost four times higher than in California.Conclusion Hardcore smoking presents a serious challenge to public health efforts to reduce the prevalence of smoking, but the proportion of hardcore smokers does not necessarily increase as overall prevalence in a population declines. More hardcore smokers could be persuaded to quit, but this will require interventions that are targeted to the particular needs and perceptions of both socially disadvantaged and older smokers.     

A smoking cessation intervention program for family physicians.

Family physicians are able to approach many patients who smoke but are often hesitant to help them quit. Lack of knowledge about effective interventions is a major reason for this hesitancy. The important components that have been tested in physician-initiated smoking cessation interventions are advice to quit, information about the risks of smoking and techniques for quitting, nicotine gum, setting a date for quitting and offers of supportive follow-up visits. We describe a cessation program developed for family physicians that incorporates these factors into three types of visits over a 2-month period: the challenge visit, which occurs during a regular office visit and focuses on advice and setting a date to quit; the quit-date visit, which involves instructing patients on the proper use of nicotine gum, if applicable, and confirming their desire to quit; and four supportive follow-up visits, which provide continuing encouragement for 2 months and allow physicians to monitor withdrawal symptoms, relapses and other problems. Such a program can be effectively incorporated into a general practice.     

Web-based smoking cessation intervention that transitions from inpatient to outpatient: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: E-health tools are a new mechanism to expand patient care, allowing supplemental resources to usual care, including enhanced patient-provider communication. These applications to smoking cessation have not yet been tested in a hospitalized patient sample. This project aims to evaluate the effectiveness and cost-effectiveness of a tailored web-based and e-message smoking cessation program for current smokers that, upon hospital discharge, transitions the patient to continue a quit attempt when home (Decide2Quit). DESIGN: A randomized two-arm follow-up design will test the effectiveness of an evidence- and theoretically-based smoking cessation program designed for post-hospitalization. METHODS: 1488 patients aged 19 or older, who smoked cigarettes in the previous 30 days, are being recruited from 27 patient care areas of a large urban university hospital. Study eligible hospitalized patients receiving tobacco cessation usual care are offered study referral. Trained hospital staff assist the 744 patients who are being randomized to the intervention arm with registration and orientation to the intervention website. This e-mail and web-based program offers tailored messages as well as education, self-assessment and planning aids, and social support to promote tobacco use cessation. Condition-blind study staff assess participants for tobacco use history and behaviors, tobacco use costs-related information, co-morbidities and psychosocial factors at 0, 3, 6, and 12 months. The primary outcome is self-reported 30-day tobacco abstinence at 6 months follow-up. Secondary outcomes include 7-day point prevalence quit rates at 3, 6, and 12 months follow-up, 30-day point prevalence quit rates at 3 and 12 months, biologically confirmed tobacco abstinence at 6-months follow-up, and multiple point-prevalence quit rates based on self-reported tobacco abstinence rates at each follow-up time period. Health care utilization and quality of life are assessed at baseline, and 6 and 12 months follow-up to measure program cost-effectiveness from the hospital, health care payer, patient, and societal perspectives. DISCUSSION: Given the impact of tobacco use on medical resources, establishing feasible, cost-effective methods for reducing tobacco use is imperative. Given the minimal hospital staff burden and the automated transition to a post-hospitalization tailored intervention, this program could be an easily disseminated approach. Trial Registration: Current Intervention Trial NCT01277250.     

Improving communication skill training in patient centered medical practice for enhancing rational use of laboratory tests: The core of bioinformation for leveraging stakeholder engagement in regulatory science

Requests for laboratory tests are among the most relevant additional tools used by physicians as part of patient''s health problemsolving. However, the overestimation of complementary investigation may be linked to less reflective medical practice as a consequence of a poor physician-patient communication, and may impair patient-centered care. This scenario is likely to result from reduced consultation time, and a clinical model focused on the disease. We propose a new medical intervention program that specifically targets improving the patient-centered communication of laboratory tests results, the core of bioinformation in health care. Expectations are that medical students training in communication skills significantly improve physicians-patient relationship, reduce inappropriate use of laboratorial tests, and raise stakeholder engagement.     

Use of automobile seat restraints by children in two Canadian cities.

A telephone survey was conducted in Montreal and Calgary to determine the extent to which parents use safety restraints for their children in cars, the types of restraints used and the factors associated with such use. Of the combined sample 39% reported that their child regularly used a restraint, and 47% of the children in Montreal and 55% of those in Calgary wore an age-appropriate safety device. Birth order and the child''s and the respondent''s ages were significantly related to the use of restraints. However, the respondent''s use of seatbelts was the factor most likely to affect the rate of use of restraints for children. Although a large proportion of the parents with younger children owned a carseat, one in four did not use it regularly. Parents who did not use carseats believed they were useless or dangerous; many preferred to hold the child in their laps or arms. The seatbelt law in Quebec and the existence of a carseat rental program in Calgary appear to have had some influence on the rate of the use of restraints for children.     

Ontario Maternal Serum Screening Program: practices,knowledge and opinions of health care providers

OBJECTIVE: To determine the practices, knowledge and opinions of health care providers regarding a prenatal genetic screening program in Ontario. DESIGN: Cross-sectional self-reported survey. SETTING: Ontario. PARTICIPANTS: Random sample of 2000 family physicians, all 565 obstetricians and all 62 registered midwives in the province. Among subjects who were eligible (those providing antenatal care or attending births) the response rates were 91% (778/851), 76% (273/359) and 78% (46/59) respectively. MAIN OUTCOME MEASURES: Which patients were offered maternal serum screening (MSS), how results were being communicated, knowledge of the test''s sensitivity, likes and dislikes about MSS and recommendations regarding the program. RESULTS: Most (97%) of respondents stated that they were offering MSS to the pregnant women in their practices; 88% were offering it routinely to all pregnant women (87% of the family physicians, 90% of the obstetricians and 100% of the midwives). Most (92%) of the respondents stated that they communicate positive results to their patients personally as soon as they are received; 23% did so for negative results. The respondents correctly identified the initial positive rate but underestimated the false-positive rate. About one-third did not respond to these knowledge questions. Of those who gave feedback on the screening program, 50% recommended that it not be changed, 29% suggested that it be changed, and 22% recommended that it be scrapped. CONCLUSIONS: Participation in the Ontario Maternal Serum Screening Program by health care providers has been good, although knowledge about MSS is far from ideal. Many providers have reservations about the program. In light of concerns raised about the high false-positive rate and the anxiety such results generate in pregnant women, there is a need for more education of providers and patients and a better understanding of women''s experiences with genetic screening.     

"They're doing people a service"-qualitative study of smoking, smuggling, and social deprivation

ObjectivesTo examine the behaviour and attitudes related to smoking and contraband tobacco products among smokers in two socially deprived areas.DesignCross sectional study with qualitative semistructured interviews, augmented by smokers'' day grid.SettingTwo areas of socioeconomic deprivation in Edinburgh.Participants50 male and 50 female smokers aged 25-40 years randomly selected from general practitioners'' lists from two health centres, each located in an area of deprivation.ResultsMost smokers wanted to quit but felt unable to because of the importance of smoking in their daily routine and their addiction to nicotine. Strategies for maintaining consumption levels in the face of increasing cigarette prices and low income included purchasing contraband cigarettes and tobacco. Vendors were contacted through social networks, family, and friends as well as common knowledge of people and places, particularly pubs where contraband was available. Most users of contraband considered that smugglers were providing a valuable service. Purchasing contraband tobacco was viewed as rational in the face of material hardship. Many smokers criticised the government for its high tobacco taxation and the lack of local services to help them to stop smoking.ConclusionsSmokers in deprived areas perceive a lack of support to help them to stop smoking. Cigarette and tobacco smuggling is therefore viewed positively by low income smokers as a way of dealing with the increasing cost of cigarettes. Smokers in areas of deprivation may thus show little support for tackling smuggling until more action is taken to deal with the material and personal factors that make it difficult for them to quit.

What is already known on this topic

Areas of deprivation have the highest rates of smoking and lowest levels of cessationAround 25-30% of cigarettes consumed in the United Kingdom are contrabandWe know little about the attitudes of smokers in these areas to smuggled cigarettes or whether and how they access them

What this study adds

In such areas the easy availability of cheap tobacco products through contraband networks works against many smokers'' desire to quitGiven the perceived lack of support to help them to stop smoking, this smuggling network is viewed positively by low income smokers as a way of dealing with the increasing cost of cigarettesSmokers in areas of deprivation may thus show little support for tackling smuggling until more action is taken to address the material and personal factors that make it difficult for them to quit     

Does breathing other people's tobacco smoke cause lung cancer?

The available epidemiological studies of lung cancer and exposure to other people''s tobacco smoke, in which exposure was assessed by whether or not a person classified as a non-smoker lived with a smoker, were identified and the results combined. There were 10 case-control studies and three prospective studies. Overall, there was a highly significant 35% increase in the risk of lung cancer among non-smokers living with smokers compared with non-smokers living with non-smokers (relative risk 1.35, 95% confidence interval 1.19 to 1.54). Part of this increase was almost certainly caused by the misclassification of some smokers as non-smokers. As smokers, who are more likely to get lung cancer than non-smokers, tend to live with smokers this misclassification probably exaggerated the estimated increase in risk. Adjustment for this error reduced the estimate to 30% (relative risk 1.30), but as people who live with non-smokers may still be exposed to other people''s smoke this estimate was revised again to allow for the fact that a truly unexposed reference group was not used. The increase in risk among non-smokers living with smokers compared with a completely unexposed group was thus estimated as 53% (relative risk of 1.53). This analysis, and the fact that non-smokers breathe environmental tobacco smoke, which contains carcinogens, into their lungs and that the generally accepted view is that there is no safe threshold for the effect of carcinogens, leads to the conclusion that breathing other people''s tobacco smoke is a cause of lung cancer. About a third of the cases of lung cancer in non-smokers who live with smokers, and about a quarter of the cases in non-smokers in general, may be attributed to such exposure.     

Effectiveness of the Quick Medical Reference as a diagnostic tool

A number of computer-based systems with diagnostic capabilities have been developed for internal medicine. Quick Medical Reference (QMR) is one such program. The authors describe key features of QMR and report on their study of its effectiveness as a diagnostic tool. They investigated how frequently the correct diagnosis would appear among the 5 highest ranked diagnoses generated by QMR. The charts of 1144 consecutive patients admitted to a teaching unit were retrospectively screened. Eligible cases included those referred for investigation of an undiagnosed illness with an objectively proven final diagnosis (n = 154). Two physicians familiar with, but not experts in, the use of QMR entered clinical information abstracted from the patients'' charts into the program. Physician A obtained the correct diagnosis in 62 (40%) of the 154 cases, and physician B was successful in 56 (36%) of the cases. The authors use study cases to illustrate QMR''s strengths and weaknesses.     

Improving benzodiazepine prescribing in family practice through review and education.

Indications for and dosages of four commonly prescribed benzodiazepines were recorded at a family medicine centre with the aid of a computerized data collection system. Four guidelines were then developed for appropriate prescribing of these drugs: (a) benzodiazepines should be used less frequently with increasing age; (b) short-acting drugs are preferable to long-acting drugs; (c) patients 65 years of age and over should receive half the daily dose prescribed for younger patients; and (d) use of these drugs for more than 1 month should be discouraged. After a year''s observation it was evident that none of the guidelines were being followed. The 30 physicians in the practice were then informed of the findings by an educational program. Another 6 months of observation showed a reduction in the prescribing of benzodiazepines to patients 65 years of age and over, a significant shift to the use of short-acting benzodiazepines, and some reduction in the daily dose and duration of administration of diazepam. Thus, such a review of drug prescribing in family practice can be a practical and effective method of improving prescribing patterns.     

Acupuncture in Nevada

Nevada''s Senate Bill 448 was signed into law by Governor Mike O''Callaghan on 20 April 1973. The law permits the practice of Chinese medicine, including acupuncture, by practitioners who do not have to be physicians. The state legislature rapidly approved it with only two dissenters, one of them a physician.Similar legislation may be considered in other states this year.
