The end-of-study patient survey: methods influencing response rate in the AVID Trial.

Patient surveys are commonly distributed at the end of a multicenter clinical trial. This Antiarrhythmics Versus Implantable Defibrillators (AVID) substudy prospectively explored the relationship between methods used in distributing a survey and the quantity of responses received. AVID was a multicenter, randomized trial comparing survival in arrhythmia patients treated with antiarrhythmic drugs versus implantable defibrillators. At study termination, a patient satisfaction survey was mailed to the 664 surviving participants. Questions included reasons for study participation, study benefits and problems and quality of care. Survey mailings were stratified by four factors in a 2x2x2x2 factorial design: delivery mode (overnight vs. regular mail), certificate of appreciation, timing of administration ("early" vs. "late") and cover letter signed by a physician versus coordinator. Patients were randomly assigned to received one of 16 combinations of these four factors. Clinical characteristics and response rates were evaluated. Patients were more likely to return surveys delivered by overnight mail (75% vs. 68%, p=0.04), with no certificate of appreciation enclosed (75% vs. 68%, p=0.05) and administered close to the time of study closeout (79% vs. 72%, p=0.085). Compared to the 184 nonrespondents, the 456 (71%) respondents were older, Caucasian, lived with others, were high school graduates and less likely to have Medicare/Medicaid or HMO insurance (p<0.03). Physician recommendation was the most common reason cited for trial participation. Main benefits included increased knowledge of their medical condition and improved health. Reported problems included parking, transportation and excess clinic wait time. This randomized study demonstrated that methods of patient survey distribution affect the survey return rate. Additional studies should explore mechanisms for maximizing return rates.

[Communications between hospital laboratory personnel and physicians].

The availability of internet facilities have been spreading rapidly and widely over the past several years. We publish a laboratory data handbook every year and distribute this to physicians in our hospital. Recently we have moved the information to our web site of the Internet. Using the web site, physicians can refer to the information on a 24-hour basis. This information includes: reference ranges; correlation of data obtained by previous and new methods; procedures for ordering each type of laboratory test. Furthermore, anyone can send questions and opinions by E-mail through the web page. The graphs which show the average values of patient results for each day can be obtained by using our database. These graphs are useful for long-range quality management of precision. Another important application is displaying histograms showing the distribution of test results between patients with a specific disease and healthy subjects. The application is expected to facilitate progress in laboratory medicine.

Growth and determinants of access in patient e-mail and Internet use.

OBJECTIVES: To measure the rate of access to and use of the Internet and e-mail, to determine sociodemographic predictors of access, and to measure the change in Internet and e-mail access over a 1-year interval. DESIGN: Survey study. Comparison of data with those from a similar survey from 1998. SETTING: Emergency department of a large urban pediatric teaching hospital. PARTICIPANTS: Primary caretakers of pediatric patients or the patients themselves if aged 16 years or older. MAIN OUTCOME MEASURES: Use of and access to the Internet or e-mail. RESULTS: We surveyed 214 individuals: 72.8% use or have access to the Internet, e-mail, or both, an increase from 52.2% in the 1998 survey (P<.001), and 48.5% regularly use the Internet or e-mail, compared with 43.1% in 1998 (P = .32). Outside the home, access is primarily at work (52.2%), schools (8.9%), public libraries (11.5%), and friends' and relatives' houses (16.7%). Internet use and access are linearly correlated with income (r = 0.43; P<.001). White patients are more likely to have access (odds ratio, 2.6; 95% confidence interval, 1.3-5.4; P<.001) than black or Asian patients, whereas those of Hispanic ethnicity are less likely to have access (odds ratio, 0.20; 95% confidence interval, 0.09-0.43; P<.001). However, after adjustment for race and Hispanic ethnicity, only income was a significant predictor of family access to the Internet and e-mail. CONCLUSIONS: During the past year, many patients have gained access to the Internet and e-mail, although rates of regular use have remained steady. This access is often from outside the home. Furthermore, access is directly related to income and is unevenly distributed across racial and ethnic groups.

Physicians' and patients' attitudes toward manual medicine: implications for continuing medical education.

INTRODUCTION: Manual medicine (MM) is a physical modality infrequently used in primary care clinics. This study examines primary care physicians' experience with and attitudes toward the use of MM in the primary care setting, as well as patients' experience with and attitudes toward MM. METHODS: Surveys were distributed to a convenience sample of physicians (54.3% response rate) attending a 1-week primary care continuing medical education (CME) conference in Kentucky. Similar surveys were also mailed to a random sample of primary care patients (35.3% response rate) living in a service region in which most conference attendees practiced. RESULTS: Similar responses were obtained from physicians and patients. A majority (81% and 76%, respectively) of physicians and patients felt that MM was safe, and over half (56% of physicians and 59% of patients) felt that MM should be available in the primary care setting. Although less than half (40%) of the physicians reported any educational exposure to MM and less than one-quarter (20%) have administered MM in their practice, most (71%) respondents endorsed desiring more instruction in MM. The majority of those seeking additional educational exposure (56%) were willing to pay for MM training that included CME credit. DISCUSSION: This survey suggests that primary care physicians feel that there is currently insufficient education in MM. The majority of physicians and patients feel that MM is beneficial, safe, and appropriate for use in a primary care setting. Thus, there may be a rising demand for quality instruction in MM from physical medicine doctors and other licensed therapists who currently practice MM.

Surveying the elderly about health, medical care and living conditions. Some issues of response inconsistency.

A sample of elderly persons (75-84 years old) in Sweden was surveyed twice on home conditions, health and medical care. Two data collection methods were used: interviews and a mail survey. It has been shown that it is possible to carry out a mail survey (with low non-response) among the elderly in this group. However, what about other aspects of quality? Is it really possible to use a mail survey instead of the much more expensive and complicated techniques involved in interviewing? The results show that for certain groups of variables there are fairly large differences between how respondents reply in the mail survey and in personal interviews carried out by district nurses. These differences apply both to the degree of inconsistency in answers and to shifts in marginal distributions. Among other things, more ailments are mentioned at interview. The demand for information on the elderly and the differences between the methods in the cost of gathering this information make reliability and validity studies of methods of surveying the elderly increasingly important.

Asthma education in rural communities.

Asthma is a common disease of airway obstruction in school-aged children. Adequate management of asthma in children leads to fewer missed school days, fewer hospitalizations, fewer emergency room visits, and an increase in quality of life. Most asthma educational programs and evaluations have focused on urban rather than rural populations. The purpose of this study was to identify parental asthma needs, develop rural asthma education materials, and evaluate the effectiveness of these educational materials in improving the knowledge and asthma care effectiveness of parents of children with asthma in a rural community. Seven parents were contacted by telephone and administered a pre- and posttest questionnaire analyzing their level of knowledge about asthma and their quality of life. Asthma educational materials were mailed to all parents in the study before administering the posttest. Results indicated that all parents needed additional education about asthma, especially regarding medications. Pre- and posttest scores showed improvements in three areas of knowledge: long-term asthma medications, controlling roaches in the home, and daily peak flow monitoring. There was a significant improvement between pre- and posttest results from the activity domain of quality of life. Eighty-five percent of the parents reported that they had either initiated changes in their home, or planned to in the future, from reading the educational materials. The parents' response to the educational materials that they received by mail was positive, indicating that they may not have received enough information about how to care for children with asthma before our study. The data suggest that distribution of asthma educational materials in rural communities can increase parental knowledge about asthma and lead to positive changes in behavior that can improve their children's health.

Axillary brachial plexus block in two hundred consecutive patients.

Two hundred consecutive, minimally-sedated patients presenting for upper limb surgery were audited prospectively to determine the overall clinical success rate, extent of cutaneous neural blockade, reliability and complication rate of each indicator of axillary sheath entry, and degree of patient satisfaction. The axillary sheath was identified, using a 22 gauge, short-bevelled needle, by one of four indicators, whichever was elicited first (paraesthesia, arterial or venous puncture, or tethering by the axillary sheath). Alkalinized mepivacaine 1.2%, 50 ml then was injected. The cutaneous distribution of the block was mapped in the presence of minimal sedation. Anaesthesia was supplemented with peripheral nerve blocks where necessary. Patients were followed up with a mailed questionnaire and surgeon interview. The overall clinical success rate was 92.5%, improving to 99% with supplementary nerve blocks. Complete anaesthesia distal to the elbow was achieved in 85% of patients. Complications were common, but generally mild and transient: mild acute local anaesthetic toxicity, 3.5%; axillary tenderness and bruising, 12%; and dysaesthesias, 12.5%. Despite this, patient satisfaction was high (97%).

Child psychiatry practice patterns in Ontario.

OBJECTIVES: To examine the demographics, training, distribution, venues of practice, remuneration patterns, and professional affiliations of child psychiatrists in Ontario. METHOD: In July 1997, questionnaires were sent to 229 Ontario psychiatrists. A second mailing was sent to nonresponders in the fall of 1997. The overall response rate was 66.8%. RESULTS: Compared with other research regarding the ratio of child psychiatrists to children with mental health problems, Ontario fares relatively well (1:6148). Generally, Ontario child psychiatrists report having received formalized training in the speciality. Child psychiatrists are disproportionately concentrated in Toronto and in midsize cities with medical schools compared with rural regions. Out-reach services to smaller communities are provided by 30% of child psychiatrists, but it is not clear whether the services are sufficient and equitably available. Approximately 50% of current psychiatrists will be aged 65 years or older in 15 years, and it is unclear whether sufficient numbers will replace them. The profession appears to be reaching an equitable gender representation. Most child psychiatrists belong to the professional organizations that support the profession; however, they are least likely to belong to the Ontario Psychiatric Association (OPA). CONCLUSIONS: An optimal ratio of child psychiatrists per population served still needs to be determined, with special consideration given to the needs of rural communities. The small ratio of child psychiatrists to the population of children with mental health needs highlights the importance of collaborating with other medical and mental health professionals. Recruiting and retaining child psychiatrists will need to be monitored. Child psychiatrists in Ontario need a unified voice to address these issues.

Epidemiological field studies of animal populations.

Numerous survey designs have been developed for epidemiological field studies of human populations, most of which are also applicable to field studies of animal poulations. Each design has its own advantages and disadvantages. The final design selected for a particular study depends upon such factors as the overall purpose of the study, the geographic dimensions of the study area, the diseases incidence or prevalence and species to be studied as well as the planned use for the data. Population dynamics including the distribution and density of the species to be studied are factors that should also be considered in the initial design of a study. A surveillance system, using mailed questionnaire data and a subsequent survey using direct interviews of validate the data in a statewide study of swine birth defects are used to illustrate some of the techniques that can be applied to domestic animal populations in a fairly large geographic area. The type of data collected, its use and its limitations are also considered.

Thermoluminescence dosimetry and its applications in medicine--Part 2: History and applications.

Thermoluminescence dosimetry (TLD) has been available for dosimetry of ionising radiation for nearly 100 years. The variety of materials and their different physical forms allow the determination of different radiation qualities over a wide range of absorbed dose. This makes TL dosimeters useful in radiation protection where dose levels of microGy are monitored as well as in radiotherapy where doses up to several Gray are to be measured. The major advantages of TL detectors are their small physical size and that no cables or auxiliary equipment is required during the dose assessment. Therefore TLD is a good method for point dose measurements in phantoms as well as for in vivo dosimetry on patients during radiotherapy treatment. As an integrative dosimetric technique, it can be applied to personal dosimetry and it lends itself to the determination of dose distributions due to multiple or moving radiation sources (e.g. conformal and dynamic radiotherapy, computed tomography). In addition, TL dosimeters are easy to transport, and they can be mailed. This makes them well suited for intercomparison of doses delivered in different institutions. The present article aims at describing the various applications TLD has found in medicine by taking into consideration the physics and practice of TLD measurements which have been discussed in the first part of this review (Australas. Phys. Eng. Sci. Med. 17: 175-199, 1994).

Reliability and validity of health status measurement by the TAPQOL.

BACKGROUND: In addition to clinical measures in the evaluation of paediatric interventions, health related quality of life (HRQoL) is an important outcome. The TAPQOL (TNO-AZL Preschool children Quality of Life) was developed to measure HRQoL in preschool children. It is a generic instrument consisting of 12 scales that cover the domains physical, social, cognitive, and emotional functioning. AIMS: To evaluate the feasibility, score distribution, internal consistency, test-retest reliability, and discriminative and concurrent validity of the TAPQOL multi-item scales in preschool children, aged 2-48 months. Also to evaluate the feasibility, reliability, and validity separately for infants (2-12 months old) and toddlers (12-48 months old). METHODS: Parents of a random general population sample of 500 preschool children were sent a questionnaire by mail. A random subgroup of 159 parents who participated received a retest after two weeks. RESULTS: The response rate was 83% at the test and 75% at the retest. There were few missing answers. Six scales showed ceiling effects. Nine scales had Cronbach's alphas >0.70. In general, score distributions and Cronbach's alphas were comparable for infants and toddlers. Test-retest showed no significant differences in mean scale scores; two scales had intra-class correlations <0.50. Five scales showed significant differences between children with no conditions versus children with two or more parent reported chronic conditions. CONCLUSION: Results showed that the TAPQOL is a feasible instrument to measure HRQoL and support the reliability and discriminative validity of the majority of its scales for infants as well as toddlers.

[The status of perioperative pain therapy in Germany. Results of a representative, anonymous survey of 1,000 surgical clinic. Pain Study Group].

To evaluate the status of perioperative pain management we mailed a anonymous postal survey to all 2,254 surgical departments in Germany. We received answers from 1,000 clinics (44.4%) which were representative related to their regional distribution. We asked the responsible surgeons to report their organizational structure and responsibilities for treating pain patients, the significance of the problem, their methods of measuring pain, and the usage of different analgesic drugs and methods. In 47% the surgeon and the anesthesist together had responsibility for adequate postoperative pain treatment; in 33% and 14%, respectively, it was the surgeon and anesthesist alone. Only 41% knew the interdisciplinary statement on pain therapy of the Professional Societies of German Surgeons and Anaesthesists from 1992. Although the importance of postoperative pain is globally acknowledged, only 19.1% of all departments had a written concept for pain treatment. Pain was measured in only 11% of the clinics mainly by using the visual analogue scale. Most surgeons relieve pain solely with systemic drugs. Regional analgesia was used by 18% only 51% of the surgeons decide on the choice and dosage of analgesic therapy on the ward; 33% admit that pain therapy often starts after complaints of the patient. 70% of all surgeons never participated in a congress on pain. We conclude that postoperative pain management in most German surgical departments still lacks effectiveness, adequacy, and organizational and scientific background.

Trauma teams in Australia: a national survey.

BACKGROUND: Trauma teams have been associated with improved trauma patient outcomes. The present study seeks to estimate the use of trauma teams in Australian hospitals and describe their medical composition, leadership and criteria for activation. METHODS: Australian public hospitals with more than 100 beds, an emergency department and offering surgical services were identified. A survey assessing the presence, composition and means of activation of a trauma team was mailed to the 'Director, Emergency Department' of all identified hospitals. Three months later, all hospitals were contacted by telephone to complete and verify data collection. RESULTS: Questionnaires were distributed to 130 hospitals. After exclusion of hospitals that did not receive patients with traumatic injuries, and dedicated paediatric tertiary referral centres, 111 hospitals remained for analysis. Of these, 56% had an established trauma team, while 71% of hospitals without a trauma team claimed to have insufficient doctors to form one team. Ninety-five per cent of trauma teams were potentially activated by prehospital paramedic data (field triage). For 92% of trauma teams a combination of anatomical, physiological and mechanistic criteria were required for activation. The most common methods of mobilizing a trauma team were by dispatching a common call onto individual pagers (31%) or by paging trauma team members individually (31%). Fifty-eight per cent of trauma team leaders were emergency medicine specialists/registrars, while 8% of trauma teams were led by surgeons/registrars. Consultant surgeons were members of 23% of trauma teams and 74% of trauma teams consisted of more junior members after hours. Some form of trauma audit was engaged in by 64% of hospitals. CONCLUSIONS: Trauma teams are yet to be utilized by many Australian hospitals that provide trauma care. Australian surgeons presently have limited leadership roles and membership in trauma teams. Trauma audit can be more widely adopted in Australian hospitals.

Median nerve latency measurement agreement between portable and conventional methods.

A portable nerve conduction testing device was compared with a conventional method of measuring median nerve distal latencies. In a population-based study, a health questionnaire was mailed to a random sample of 3000 participants (aged 25 to 74 years). Two hundred and sixty-two responders with numbness and/or tingling in the median nerve distribution, and 125 asymptomatic responders underwent clinical examination as well as portable and conventional median nerve distal latency measurements. Motor latency measured with the portable device was on average 0.1 millisecond (ms) lower than motor latency measured with the conventional method (95% limits of agreement, -0.8-0.5 ms). Sensory latency (wrist-to-index finger) measured with the portable device was on average 0.3 ms lower than sensory latency (long finger-to-wrist) measured with the conventional method (95% limits of agreement, -0.7-0.1 ms). Strong correlations were found between the latencies measured by the portable and conventional methods (Pearson correlation coefficient, 0.90-0.93). The agreement between the portable and conventional methods in measuring median nerve distal latencies appears to be acceptable. The cut-off value for abnormal sensory latency needs to be lower for the portable than the conventional method if the present measurement techniques are used.

The occurrence and distribution of burnout among infectious diseases physicians.

The occurrence and distribution of the three dimensions of the burnout syndrome (emotional exhaustion, depersonalization, and lowered feelings of personal accomplishment) were studied among infectious diseases physicians. A written survey was mailed to the entire identified US population of infectious diseases physicians (n = 4328); a 46.3% response rate provided 1840 usable surveys. Statistical analyses of the data demonstrated that 43.5% of the physician sample reported high scores on emotional exhaustion, and 40.3% scored high on depersonalization. Personal accomplishment scores remained high, despite burnout levels, with 91.8% reporting high personal accomplishment. The highest percentage of burnout occurred among physicians in private practice settings (55%), followed by government settings (39%), and academia (37%). The high percentage of infectious diseases physicians experiencing burnout suggests the need for further research to establish trends, to determine if other types of physicians experience similar levels of burnout, to identify casual factors, and to develop avenues to reduce stress and facilitate coping.

The transtheoretical model of behavior change and smokers in southern Appalachia.

BACKGROUND: The southern Appalachian states show a high prevalence of smoking, with associated high rates of both heart disease and cancer, yet cultural differences raise questions concerning the applicability of the most frequently used model for smoking cessation, the transtheoretical model, for smokers from this region of the country. OBJECTIVE: To identify, by examining the applicability of the transtheoretical model for southern Appalachian smokers, the percentage of individuals in each of the five stages of change, the use of the processes of change from the trans-theoretical model, and the scores on recognized predictors of smoking cessation including the temptation to smoke, the perceived barriers to cessation, the pros and cons of smoking, and nicotine dependence. METHODS: This population-based, descriptive, cross-sectional study used a random sample of 3,800 telephone numbers, which were called up to eight times. The 659 smokers or former smokers who agreed to participate were mailed a written questionnaire consisting of six well-established scales that measure constructs from the transtheoretical model. The final sample consisted of 357 usable questionnaires. RESULTS: The distribution of smokers in northeastern Tennessee differed from national samples across the first three stages of change, with 56% in precontemplation, as compared with previous findings of 40% in national samples. The subjects' scores for the pros of smoking were similar across the stages of change in this sample, and although the scores for the cons differed significantly across the stages in the sample, post hoc analysis indicated that the only significant change occurred between precontemplation and contemplation. The scores for temptation to smoke did not differ significantly across the stages of change in this sample. DISCUSSION: Smokers from Appalachian Tennessee differ from smokers in other parts of the United States, and these findings raise questions about the applicability of the transtheoretical model for this population.

Paediatric trauma teams in Australia.

BACKGROUND: Trauma teams have been associated with improved survival probability of paediatric trauma patients. The present study seeks to estimate the use of trauma teams in Australian paediatric tertiary referral centres and describe their medical composition, leadership and criteria for activation. METHODS: Australian paediatric tertiary referral centres were identified. A structured questionnaire assessing the presence, composition and means of activation of a trauma team was mailed to the 'Director, Emergency Department' of all identified hospitals. Three months later, all hospitals were contacted by telephone to complete and verify data collection. RESULTS: Questionnaires were distributed to eight hospitals. Seventy-five per cent had an established trauma team. Hospitals without a trauma team claimed to have insufficient doctors to form a team and insufficient trauma caseload to justify a team. All trauma teams were potentially activated by prehospital paramedic data (field triage) and required a combination of anatomical, physiological and mechanistic criteria for activation. The two methods of mobilizing a trauma team were by dispatching a common call onto individual pagers (66%) or a specific trauma pager (33%) carried by trauma team members. Fifty per cent of hospitals had a two-tier, stratified trauma team response. All teams consisted of emergency, surgical and intensive care unit registrars. Trauma team leaders were emergency medicine specialists/registrars (33%), surgical registrars (33%) and non-defined (33%). Consultant surgeons were not members of any trauma team. Eighty-three per cent of trauma teams consisted of more junior members after hours. Fifty per cent of hospitals did not have a surgical registrar on site outside of business hours. Eighty-eight per cent of hospitals engaged in some form of trauma audit. CONCLUSIONS: Trauma teams are utilized by most Australian paediatric tertiary referral centres, with fairly uniform medical composition and criteria for activation. Paediatric surgeons presently have limited leadership roles and membership of Australian paediatric trauma teams.
