Local anesthetic use by dentists in Ontario.

A mail survey to obtain data on the annual use of local anesthetics in dentistry was sent to each of the 6,271 certified dentists in Ontario in 1993. The survey asked dentists to identify the different types and total amounts of local anesthetics used in their practice yearly. A total of 2,426 dentists responded to the survey. Based on extrapolation of the data collected, it is estimated that more than 11,000,000 cartridges of local anesthetic are administered annually by dentists in Ontario. The distribution of use of specific types of local anesthetics and vasoconstrictors was also determined. Lidocaine with 1:100,000 epinephrine accounted for 23.4 per cent of all cartridges used, followed by articaine with 1:200,000 epinephrine (19.9 per cent), articaine with 1:100,000 epinephrine (17.9 per cent), prilocaine with 1:200,000 epinephrine (16.4 per cent), mepivacaine with 1:20,000 levonordefrin (6.4 per cent), and mepivacaine plain (6.3 per cent). Other anesthetics were used to a lesser degree. Further analysis revealed no statistically-significant differences in the use of local anesthetics among dentists who responded to the survey and non-responders. The results of this survey document the current use of local anesthetics in dentistry.

Performance of a self-administered mailed version of the Quality of Well-Being (QWB-SA) questionnaire among older adults.

OBJECTIVES: The Quality of Well-Being questionnaire is a measure of health-related quality of life (HRQoL) that has several desirable properties. Its widespread use has been hindered because it is difficult to administer. To overcome this limitation, a new self-administered form has recently been developed. This study examined the feasibility of using the Quality of Well-Being-Self-Administered (QWB-SA) questionnaire in an older population. METHODS: The Quality of Well-Being-Self-Administered questionnaire was sent to 430 community-dwelling individuals aged 65 years and older who were randomly selected from primary care physicians' offices. Response patterns, scaling distributions, and the acceptability of the survey were examined for all respondents. The results of the QWB-SA questionnaire were compared to the Sickness Impact Profile (SIP) and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) for those individuals who also had completed the latter two surveys approximately 10 months earlier and whose health had not changed substantially in the meantime. RESULTS: Three hundred and one older adults (70%) responded. The mean QWB-SA questionnaire score was 0.7035. The scores were not skewed, and there were no floor or ceiling effects. The mean time to complete the QWB-SA questionnaire was 14.2 minutes, which was significantly shorter than for the SIP (19.3 minutes) but significantly longer than for the SF-36 (12.5 minutes). Subjects rated their satisfaction with the QWB-SA questionnaire somewhat lower than for the SIP and similar to SF-36. Correlations between the QWB-SA questionnaire and the SIP and SF-36 were moderate and were generally stronger for measures of physical health than for other domains such as mental health. CONCLUSIONS: The self-administered QWB questionnaire was acceptable to older respondents, and it correlated with other measures of health-related quality of life. It can be considered as a candidate for some research applications among older adults.

Call and recall for cervical cancer screening in a developing country: a randomised field trial.

A randomised field trial was used to assess Mexican women's response to a mailed invitation for a Papanicolaou test. A sample of 4,802 women, 20 to 64 years old, chosen at random from the Mexican Social Security Institute Register were randomly assigned to an intervention and to a control group. A letter of invitation and a reminder were sent to the intervention group. A letter was also sent to the control group at the end of the follow-up period (8.5 weeks) in order to compare the response among women who received a letter in both groups. Cumulative incidence and incidence rates were used to determine the response and the speed of response, respectively. The response among women who had received the letter was 33.5% (efficacy) in the intervention group, while 5.9% (p<0.001) in the control group attended a Papanicolaou test. For the total of women invited, the response was 20.1% (effectiveness) and 3.3% (p<0.001), respectively. The response was greater in rural areas (rural vs. urban/suburban; p = 0.002) and eldest women (50-64 vs. 20-49; p = 0. 02). The response rate was 7 times grater in the intervention than in the control group (RR = 7.1; 95% CI 5.4-9.4; p < 0.001). A mailed invitation to have a Papanicolaou test substantially increases attendance by women who receive it. A mailed reminder improves results. This strategy could be implemented in addition to the ones already in use, mainly among rural and elderly women.

A comparison of cigarette smokers recruited through the Internet or by mail.

OBJECTIVES: To compare smokers recruited by mail or through the Internet. METHODS: A questionnaire was mailed to 19,352 inhabitants of Switzerland in 1998, in an effort to enroll them in a smoking cessation trial. The same questionnaire was also available on the Internet. Furthermore, we mailed a survey to a representative sample (n = 1000) of the population of Geneva, Switzerland, in 1996. In this study, we compare three groups: 1027 smokers recruited through the Internet, 2961 volunteer trial participants recruited by mail (response rate 16%), and 211 smokers in the representative sample also recruited by mail (response rate 75%). RESULTS: Smokers self-recruited through the Internet were younger, more educated, more motivated to quit smoking and smoked more cigarettes per day than smokers in the other samples. Compared to trial participants, Internet participants had more negative attitudes towards smoking, higher self-efficacy scores, and were more addicted to tobacco. The strength of associations between smoking-related variables was similar in Internet and trial participants. CONCLUSION: As expected, the three groups of smokers differed on several characteristics. However, bias in distributions of variables did not imply bias in associations between variables. Thus, Internet recruitment is a potentially useful method for analytical studies that focus on associations between variables.

Sixteen-year-old oral contraceptive users in Finland, 1981-1993.

While adolescent fertility and abortion rates continue to decline in Finland, regional variations in teenage pregnancies persist, particularly among 16-17-year-olds. We studied differences in the use of oral contraceptives (OCs) among 16-year-old girls according to sociodemographic variables between 1981 and 1993. Questionnaires were mailed to national samples (N = 462-1594) of 16-year-old girls biannually, giving response rates ranging from 86% to 91% (the Adolescent Health and Lifestyle Survey). The increasing trend in OC use levelled off in 1989 at around 17-19%. OC use was most frequent in the lower socioeconomic groups, least frequent in the rural areas, but did not vary significantly according to region of the country. The pace of adopting OCs did not vary across the socioeconomic groups or regions. The socioeconomic and regional distributions of OC use were consistent with previous studies on teenage sexual activity. The results suggest equal accessibility of family planning services; regional variation in pregnancy rates cannot be explained by unequal distribution of OC use.

Videoconferencing in psychiatry: a survey of use in northern Norway.

A survey of the use of videoconferencing in mental health care was carried out in northern Norway. A questionnaire was distributed to all user institutions in northern Norway at the same time that ISDN became available, in mid-1995. The questionnaire completion rate for locations recorded as participants in videoconferencing sessions was 62%. Within six months, a total of 1028 persons had participated in 140 videoconferencing sessions from 35 institutions. The purposes of videoconferencing included meetings (50%), supervision, training and teaching (31%), clinical consultations (14%) and tests or demonstrations (5%). The alternative forms of contact which videoconferencing replaced included travel (59%), no contact (25%), telephone (14%), and mail or fax (2%). No problems were reported in 55% of the sessions; in 19% there were audio problems, in 14% there were picture problems, in 5% attempts to connect failed and in 5% disconnection occurred. The majority of users (87%) reported that they were satisfied or very satisfied with the facility; 8% were uncertain and 5% were less satisfied or totally dissatisfied. Continued surveying will provide longitudinal data on the diffusion of telepsychiatry in northern Norway.

Tobacco control activities in U.S. dental practices.

The authors surveyed general dentists, periodontists, pediatric dentists and dental hygienists in three U.S. geographical regions to estimate the percentage who practiced tobacco use cessation activities in their dental offices. A total of 1,746 dentists and 723 dental hygienists completed either a long or short version of a mailed survey or telephone interview. The authors found that tobacco cessation activities are not a routine part of dental practice and that tobacco control activities and training vary by dentist type and geographical region.

The importance of decisional balance and self-efficacy in relation to stages of change for fruit and vegetable intakes by young adults.

PURPOSE: To examine the stages of change, decisional balance, and self-efficacy constructs in relation to fruit and vegetable intakes by young adults 18-24 years old. DESIGN: A cross-sectional project was conducted by 10 states in January-July 2000 to examine decisional balance and self-efficacy in relation to stage of change for increasing fruit and vegetable intake among young adults. SUBJECTS: In all, 1545 usable surveys were returned (response rate = 55%). More non-respondents were men and precontemplators than respondents. Sixty-one percent of respondents were women, 90.3% were white, and 49.7% were current students. SETTING: Alabama, Kansas, Maine, Michigan, Nebraska, New York, Rhode Island, Oregon, South Dakota, and Wisconsin. MEASURES: A telephone screening interview and a self-administered mail survey. ANALYSIS: Analysis of variance, principal components analysis, cluster analysis, and chi 2 test. RESULTS: From precontemplation to maintenance, a significant linear trend was found toward higher food intake and self-efficacy for fruits and vegetables. The patterns of shifts in the pros and cons across the stages resembled those of other health behaviors. The decisional balance items were further classified into five component factors that varied significantly in importance across the stages. Four subject clusters were derived (unconcerned, reluctant, exploring, and action-oriented); distribution of the clusters agreed with that of the five stages. CONCLUSIONS: This study supports applicability of the Transtheoretical Model for assessing fruit and vegetable consumption by young adults. Derivation of the four clusters implies the importance of including decisional balance and self-efficacy as outcome measures besides dietary behavior for evaluating the effectiveness of nutrition interventions.

State scholarship, loan forgiveness, and related programs: the unheralded safety net.

CONTEXT: In the mid-1980s, states expanded their initiatives of scholarships, loan repayment programs, and similar incentives to recruit primary care practitioners into underserved areas. With no national coordination or mandate to publicize these efforts, little is known about these state programs and their recent growth. OBJECTIVES: To identify and describe state programs that provide financial support to physicians and midlevel practitioners in exchange for a period of service in underserved areas, and to begin to assess the magnitude of the contributions of these programs to the US health care safety net. DESIGN: Cross-sectional, descriptive study of data collected by telephone, mail questionnaires, and through other available documents, (eg, program brochures, Web sites). SETTING AND PARTICIPANTS: All state programs operating in 1996 that provided financial support in exchange for service in defined underserved areas to student, resident, and practicing physicians; nurse practitioners; physician assistants; and nurse midwives. We excluded local community initiatives and programs that received federal support, including that from the National Health Service Corps. MAIN OUTCOME MEASURES: Number and types of state support-for-service programs in 1996; trends in program types and numbers since 1990; distribution of programs across states; numbers of participating physicians and other practitioners in 1996; numbers in state programs relative to federal programs; and basic features of state programs. RESULTS: In 1996, there were 82 eligible programs operating in 41 states, including 29 loan repayment programs, 29 scholarship programs, 11 loan programs, 8 direct financial incentive programs, and 5 resident support programs. Programs more than doubled in number between 1990 (n = 39) and 1996 (n = 82). In 1996, an estimated 1306 physicians and 370 midlevel practitioners were serving obligations to these state programs, a number comparable with those in federal programs. Common features of state programs were a mission to influence the distribution of the health care workforce within their states' borders, an emphasis on primary care, and reliance on annual state appropriations and other public funding mechanisms. CONCLUSIONS: In 1996, states fielded an obligated primary care workforce comparable in size to the better-known federal programs. These state programs constitute a major portion of the US health care safety net, and their activities should be monitored, coordinated, and evaluated. State programs should not be omitted from listings of safety-net initiatives or overlooked in future plans to further improve health care access. JAMA. 2000;284:2084-2092.

Generics market in Greece: the pharmaceutical industry's beliefs.

The aim of this study was to investigate the beliefs and perspectives of the pharmaceutical industry on generic medication in Greece. Questionnaires were mailed to all 58 members of the Hellenic Association of Pharmaceutical Companies from November 2002 to February 2003. The response rate was 52%, namely 30 questionnaires were completed and returned. The questionnaire requested information on companies' involvement in generics, their opinion on generics' characteristics and on public policies affecting the demand and supply of generic medication. A descriptive analysis of the outcomes, that is percentage comparison through binomial tests and Fisher tests, was performed. According to our findings, 43% of the respondents were involved in the production and distribution of generics and the mean period of their involvement was 12 years. The majority of the respondents were in favor of their companies' involvement in generics, despite the relatively small market share of generics in Greece; 9.7% of total pharmaceutical market in 2003. Bearing in mind that in Greece the promotion of generics is not encouraged, pharmaceutical companies believe that the mandatory introduction of bioequivalence studies is an indirect promotional strategy towards generics. Additionally, the majority declared that their main competitive advantages are their safety, efficacy and effectiveness as well as their economic benefit to the society. Finally, the respondents expressed their preference for the introduction of pharmacoeconomic submissions for drugs' reimbursement by social insurance funds.

A comparison of information retention at an initial orthodontic consultation.

The exchange of information is an everyday part of orthodontic treatment. However, the amount of information that is understood and retained, by patients and their parents, is not known. There has been very little research in the area of information retention in dentistry. This has implications with the demands for improved provision of information for patients. This questionnaire-based study, compared the effectiveness of written, verbal, and visual methods of providing orthodontic information. It assessed the retention of this information, by patients and parents, in both the short- and long-term. Twenty-eight patients and their parents, were allocated alternately into one of three groups, receiving written, verbal, or visual information. Short-term retention of knowledge was assessed 10-15 minutes after receiving the information and long-term retention rated by a second questionnaire mailed 8 weeks later. Overall, little difference was found between the three methods. The findings suggested that verbal information should not be given to patients unless supplemented by written and/or visual information, and that parents were more attentive to verbal instructions than their children.

Composite resin esthetic dentistry survey in New England.

This study collected information on various aspects of esthetic dentistry, including the time used and income produced while delivering treatment to noncarious teeth. A mail survey was sent to 521 randomly selected dentists in the six-state New England area (approximately 7% of the total active dentists in that region); the response rate was 74%. The results indicated that dentists are providing a substantial amount of esthetic treatment on noncarious teeth.

Combat and herbicide exposures in Vietnam among a sample of American Legionnaires.

A cross-sectional survey of 6810 randomly selected members of The American Legion in six states who served in the U.S. Armed Forces during the Vietnam Era was conducted by a mailed questionnaire. Combat stress was evaluated by a previously validated eight-item scale. Exposure to Agent Orange and other herbicides was estimated via exposure probability index previously developed by the authors which uses an algorithm based on the combined Air Force and Joint Services HERBS files of spray data. Two-fifths of the men had served in Southeast Asia, generally at the same time during which the major proportion of herbicides were used; the remaining subjects served elsewhere. Both combat and Agent Orange exposure exhibited distinct, meaningful distributions among Vietnam veterans with service in Southeast Asia and were also correlated with each other (r = 0.24). Our analysis demonstrates conclusively that mere presence in Vietnam cannot be used as a proxy for exposure to Agent Orange. Categorization of Vietnam veterans according to herbicide exposure can be successfully accomplished, based on an existing detailed herbicide application data base. This analysis, together with the consistent dose-related results obtained in this series of papers on health and behavioral effects, demonstrates the utility of questionnaire-derived herbicide and combat exposure measures for epidemiologic study of Vietnam veterans.

Secure HL7 transactions using Internet mail (Internet draft).

The document describes the applicability of the Internet standardisation efforts on secure electronic data interchange (EDI) transactions for Health Level-7 (HL7), an EDI standard for Healthcare used world-wide. The document heavily relies on the work in progress by the IETF EDIINT working group. It is in most parts a restatement of the EDIINTs requirements document and application statement 1 (AS#1) tailored to the needs of the HL7 audience. The authors tried to make the document as self consistent as possible. The goal is to give to the reader who is not a security or Internet standards expert enough foundational and detail information to enable him to build communication software that complies to the Internet standards. Even though the authors rely on and promote the respective Internet standards and drafts, they did not withstand from commenting on and criticising the work where they see upcoming problems in use with HL7 or other EDI protocols that have not been in the initial focus of the EDIINT working group. The authors make suggestions to add parameters to the specification of the MIME type for EDI messages in RFC 1767 in order to enhance functionality. The authors give use cases for a larger subset of disposition types and modifiers of message disposition notifications. One key issue where the document goes beyond the current EDIINT drafts is the concept of non-repudiation of commitment to an EDI transaction. Secure EDI transactions should be regarded as "distributed contracts," i.e. not only the sending and receiving of single messages should be non-refutable but also the connection between messages interchanges. In anticipation of this requirement HL7 usually requires a response message to be sent to acknowledge every transaction. The authors therefore have the requirement to securely couple an EDI response message to its request message. Given the current shape of RFC 1767 this is generally possible only if a response message is coupled with an MDN receipt and the combination of both signed by the responder. The document describes a protocol to bundle MDN and response that uses the MIME multi-part/related content type in RFC 2112.

Effects of vaccine information pamphlets on parents' attitudes.

OBJECTIVES: To describe how parents actually use federally mandated vaccine information pamphlets and to evaluate the pamphlets' effects on parents' opinions about vaccination. DESIGN: A controlled trial of vaccine information pamphlets based on a survey mailed to parents who either received (n = 140) or did not receive (n = 167) the pamphlets. STUDY POPULATION: Parents of infants aged 2 to 8 months in a suburban, mainly upper-middle class private group practice in northern California. RESULTS: More than 90% of parents believed that they had enough information to decide whether their child should be vaccinated, even among those who did not receive the pamphlets. Among parents who received the pamphlets, fewer than half (38%) read them thoroughly, and most (63%) said that they should be distributed only on the first visit for vaccinations. Parents who received the pamphlets did not differ from those who did not in terms of the proportions who would have liked more time to be spent discussing vaccines (34% vs 34%) or who were anxious about how the diphtheria and tetanus toxoids and pertussis vaccine would affect their child (60% vs 52%). CONCLUSIONS: Vaccine information pamphlets, when used as an adjunct to discussions with physicians and nurses, have little effect on the opinions of well-educated parents. Future research and policy changes might focus on how to make the contents of the pamphlets less frightening and on allowing greater flexibility in how they are distributed.

Dental services utilization between 1977 and 1995 by Finnish adolescents of different socioeconomic levels.

Equal distribution of health care services has long been a major goal of health policy in the Nordic countries. According to these guidelines, every child is expected to have an examination and treatment at least every second year. The aim of this study was to analyze the trends and, in particular, the socioeconomic differences in dental visits between 1977 and 1995. The data were collected as part of a nationwide research program, the Adolescent Health and Lifestyle Survey, which began in 1977. Every second year a self-administered questionnaire was mailed to a representative sample of 14-, 16- and 18-year-old Finns. The sample sizes in the surveys varied from 2422 to 9556, making a total of 56,605 subjects in the whole study. The response rates in different years varied from 77% to 88%. The percentage of adolescents visiting a dentist increased between 1977 and 1981 and thereafter remained stable. Dental visits seemed to correlate with the occupational and educational status of the parents up to 1983, but not after that. The Finnish primary oral health care policy seems to have gained a major objective by eliminating social inequality in dental service utilization among adolescents.

Overuse injuries in triathletes. A study of the 1986 Seafair Triathlon.

A questionnaire was mailed to 600 to 657 finishers in the Seafair Triathlon (July 20, 1986); 45% of those polled returned the questionnaire. Over the preceding year, 49% of the respondents suffered a training-related injury serious enough to cause them to stop training for at least 1 day, seek medical care, or take medicine, Seventy percent of the injuries were due solely or partly to running. The knee, shoulder, and ankle were most frequently affected. Female triathletes and those more than 40 years of age showed a similar injury incidence and distribution. Elite triathletes averaged more miles per week in each sport than the athletes as a whole and showed a higher incidence of injury (60%), although this was not a significant difference. Higher weekly swimming, cycling, and running mileages did not lead to a higher incidence of injury. The likelihood of injury was independent of age, sex, body mass index, mileage per week, or other training factors evaluated in the study.

The patient advocate view.

Inflammatory breast cancer (IBC) is considered a rare disease by researchers and clinicians, and is classified as such by the Office of Rare Diseases by having a prevalence of fewer than 200,000 affected persons in the United States [5]. To affected persons, their family and friends, however, IBC is not rare; it is real, it is here, it is pain, its treatment is often filled with its own pain. As with many other diseases, IBC demands that patients be their own best advocate; no one is pre-trained for this role, it is all on-the-job-training. The "IBC Community" is comprised of those who have been diagnosed with IBC, their family, their friends, and interested other persons. It is a passionate, committed community, knit together principally by the Internet, e-mail, and telephone. The Inflammatory Breast Cancer Research Foundation was founded in 1999 by advocates, and focuses on education and awareness of IBC symptoms, diagnosis, and treatment, as well as assisting researchers and clinicians investigate IBC, the results of which will be of diagnostic and treatment value.
