Laparoscopic cholecystectomy in Brazil: analysis of 33,563 cases.

The authors present the results obtained in 33,563 laparoscopic cholecystectomies performed in Brazil from 1990 to 1995. Data were obtained by mailing questionnaires to 220 Services, 118 of which responded. The features included the year when the service started its activities, patient distribution by sex and age, surgical indications, prophylaxis with antibiotics, use of nasogastric and vesical catheters, technique used to produce pneumoperitoneum, intraoperative cholangiography, management of choledocholithiasis, necessity and causes of conversion to open surgery, surgical time, intra and postoperative complications, time of hospitalization, mortality, patient return to normal activities, and laparoscopic cholecystectomy in pregnancy. Analysis of the results demonstrated that the data are equivalent to those obtained in leading world countries and at times even better in terms of lesion of the main bile duct, time of hospitalization, etc.

A multiethnic cohort in Hawaii and Los Angeles: baseline characteristics.

The authors describe the design and implementation of a large multiethnic cohort established to study diet and cancer in the United States. They detail the source of the subjects, sample size, questionnaire development, pilot work, and approaches to future analyses. The cohort consists of 215,251 adult men and women (age 45-75 years at baseline) living in Hawaii and in California (primarily Los Angeles County) with the following ethnic distribution: African-American (16.3%), Latino (22.0%), Japanese-American (26.4%), Native Hawaiian (6.5%), White (22.9%), and other ancestry (5.8%). From 1993 to 1996, participants entered the cohort by completing a 26-page, self-administered mail questionnaire that elicited a quantitative food frequency history, along with demographic and other information. Response rates ranged from 20% in Latinos to 49% in Japanese-Americans. As expected, both within and among ethnic groups, the questionnaire data show substantial variations in dietary intakes (nutrients as well as foods) and in the distributions of non-dietary risk factors (including smoking, alcohol consumption, obesity, and physical activity). When compared with corresponding ethnic-specific cancer incidence rates, the findings provide tentative support for several current dietary hypotheses. As sufficient numbers of cancer cases are identified through surveillance of the cohort, dietary and other hypotheses will be tested in prospective analyses.

Internet health information use and e-mail access by parents attending a paediatric emergency department.

OBJECTIVES: To document internet access and health related usage patterns by families of children in a large paediatric emergency department (ED), and to discover if parents want the internet to become a tool for transferring medical test results. METHODS: This was a pre-tested, 21 item, interview conducted with parents at the paediatric ED in Toronto over 3 months. Descriptive statistics and frequency distributions were calculated and variables associated with parents wishing to access results electronically were examined. RESULTS: In total, 950 parents completed the interview (93%), of whom 87% reported routine internet access, 75% reported having an e-mail account, and 60% accessed their e-mail once or more a day. Over half (56%) reported searching the internet for health related information, with 8.5% of these searching immediately preceding their visit. Nearly three quarters (73%) indicated they would like to receive an e-mail containing the results of tests conducted in the ED; 66% of all respondents and 89% of those with e-mail indicated that they would like their child's primary care provider to receive information electronically. CONCLUSION: The majority of families have internet access and most want to receive medical information electronically and to send it to the primary provider. The vast use of internet for health related information emphasises the need to guide parents regarding reliable resources online, possibly as part of their ED visit.

Evaluation of two strategies for heart health promotion by direct mail in a low-income urban community.

BACKGROUND: The objective of this study was to evaluate the reach of mass mailings of heart health education print materials in a low-income, urban community. Materials included a monthly newsletter and a self-help behavior change kit, both distributed to all 12,789 households in the study community. METHODS: Recall, use, and self-reported impact of the materials were measured in a cross-sectional survey of a random sample of 345 adults conducted 2 weeks after distribution of the kit and 18 months after delivery of the first newsletter. RESULTS: Over one-third of the subjects (38.6%) recalled the newsletter and 27.9% had read one or more newsletters; 21.7% recalled the kit and 10.8% had read it. Few subjects had read both materials. Female gender and older age were independent correlates of having seen and read the newsletters. Older age, being widowed/separated/divorced, and infrequent physical activity were correlates of having seen and read the kit. CONCLUSIONS: Although the newsletter and kit formats might appeal to different segments of the population, mass mailings of heart health education print materials in a low-income urban community can reach large numbers of individuals. The cost effectiveness of repeated mailings of short, simple newsletters might be higher than a single mailing of a more complex behavior change kit.

A survey of residents and faculty regarding work hour limitations in surgical training programs.

HYPOTHESIS: Surgical faculty and residents have significantly different attitudes regarding work hour restrictions. SETTING: All general surgery residencies approved by the Accreditation Council for Graduate Medical Education (ACGME). PARTICIPANTS: All voluntarily participating surgical faculty and residents. MAIN OUTCOME MEASURES: Current hours worked, days off per month, and attitudes and opinions regarding the current surgical-training environment. METHODS: A 17-question survey instrument was mailed to the program directors of all ACGME-approved surgical-training programs in the United States. They were requested to distribute the survey to all faculty and residents for completion and to return the forms for analysis. RESULTS: Responses (N = 1653) were received from 46% of surgical-training programs. A significant difference was noted between faculty and resident responses in most categories. Most residents (87%) reported more than 80 duty hours per week, whereas 45% reported working more than 100 hours per week. Only 30% of residents reported an average of 1 day per week free of clinical activities. Although a minority of residents (43%) felt that their workload was excessive, 57% felt that their cognitive abilities had been impaired by fatigue. A significant number of residents (64%) and faculty (39%) believe that duty hour restrictions should be adopted. A minority of residents (20%) and faculty (47%) believe that the duration of residency training should be increased to compensate for duty hour restrictions. One quarter of residents regret choosing a career in surgery. CONCLUSIONS: Current duty hours for most surgical residents exceed the proposed ACGME limits. Although most residents support duty hour limits; surgical faculty are less supportive. Significant alterations in the current design and structure of surgical-training programs will be required to meet the ACGME guidelines.

Men, women and primary lung cancer--a Saskatchewan personal interview study.

In a previous study conducted by mail questionnaire and with a large proportion of surrogate responders, we found differences in smoking habits, age at diagnosis, tumour cell type distribution and occupational exposures between men and women who developed primary lung cancer. This study was designed to confirm those findings by conducting personal case interviews and extend them by examining the impact of certain biological factors. We have investigated demographic, smoking, occupational and medical history sex differences in cases with primary lung cancer by interviewing 273 male and 103 female cases diagnosed between November 1983 and July 1986. The females were significantly younger at diagnosis, a pattern consistent for all cell types. Squamous cell (40%), small cell anaplastic (20%) and adenocarcinomas (16%) were the most prevalent cell types in men. In women, similar frequencies of adenocarcinomas (32%) and squamous cell carcinomas (29%) occurred. Despite a higher prevalence of physician diagnosed allergy and asthma among women, minimal sex differences in the prevalence of atopy as measured by prick skin test were found. Female cases were more likely to be lifetime non-smokers (15% vs 3%), to have started smoking on average 3 years older and to smoke 6 fewer cigarettes per day. The mean pack years of female cases was significantly lower than males' for squamous, adenocarcinoma and small cell anaplastic tumours. The majority of these women had not been occupationally exposed to any substance known to be carcinogenic or to damage the lung. However, in a small subset of cases pulmonary function variables were as depressed in women as in men with significantly higher mean pack years.(ABSTRACT TRUNCATED AT 250 WORDS)

Analysis and prospects for curricular reform of medical schools in Southeast Europe.

AIM: To analyse the curricula of 16 medical schools in 6 countries in Southeast Europe in order to establish a prevailing standard curriculum against which a prospective curriculum reform could formulate its objectives. METHODS: Curricular information was gathered from a questionnaire sent via e-mail to the respective medical schools. The data collected ranged from the numbers of enrolled students to a breakdown of courses with distribution of instruction hours for certain teaching formats. For easier comparison the courses were clustered into 5 groups: pre-clinical, clinical, public health, liberal arts and electives. RESULTS: Belgrade has the highest number of undergraduate students, while Mostar has the lowest. Novi Sad, Foca/Srbinje, Zagreb, Split, Sofia, Ljubljana and Mostar have more than 5000 instruction hours, but Sarajevo lags behind with 4005 hours. Anatomy dominates the course load in Year 1, ranging from a share of 18.4% in Sofia to 11.3% in Novi Sad. Physiology dominates Year 2, ranging from 16.8% in Rijeka to 8.9% in Split, whereas in Year 3 the dominating course is pathology, reaching a peak of 13.7% in Sarajevo. Sofia has the highest number of class hours of clinical courses. The predominant public health courses are social medicine, family medicine and medical ecology. Medical English is taught at all medical schools (as electives in Ljubljana and Rijeka). CONCLUSION: There is considerable potential for curriculum improvement in the region. Teacher training, student participation, the definition of core competencies and the introduction of new methodologies should all be implemented in the process.

Integrating digital systems: commitment and collaboration.

One year ago, the radiology department at Ball Memorial Hospital, a 350-bed facility in Muncie, IN, was completely film-based. The need to support a new all-digital, 35-room emergency department (ED) hastened the facility's transition to a digital environment. Today, with the exception of mammography, the hospital's imaging services are now digital. To develop and implement the project, the hospital formed an internal implementation team. An independent consultant was also hired to evaluate the impact of these new technologies and to provide an estimated cost payback. After research, site visits, and vendor demonstrations, the hospital selected a single vendor for its picture archiving and communication system (PACS), digital radiography (DR), computed radiography (CR), and overall project management. The DR system was installed in the ED to provide digital image capture for a full range of trauma exams. The ED also initially began utilizing a Web-based PACS distribution originally implemented for after-hours teleradiology. The majority of the hospital's imaging studies are captured with 2 multi-cassette CR systems that serve 7 exam rooms in the radiology department. The hospital also installed remote operations panels to expedite entry of patient and exam information. Technologists readily embraced both CR and DR systems. The Web distribution system now transmits images to hospital-based computers and to 150 remote referring physicians. The PACS platform automatically e-mails key images and radiology reports to referring physicians. Authorized physicians can also request reports and images on an as-needed basis. The PACS vendor had previously performed multiple integrations with the radiology information system (RIS) vendor; the integration of PACS and RIS was extremely smooth. One of the critical components of a successful conversion is experienced, dedicated management. The hospital retained professional project management services to facilitate implementation and to ensure adequate training for all users.

Applying a stage model of behavior change to colon cancer screening.

BACKGROUND: There has been limited use of stages of change models in characterizing colorectal cancer (CRC) screening. We assess the applicability of the Precaution Adoption Model (PAPM) by determining the distribution of stages of adoption and by elucidating differences among stages. METHODS: The study is based on 1394 responses (69%) to a survey mailed in 2002 to patients in a primary care population. Survey measures included: self-reported CRC screening, sociodemographic characteristics, health system characteristics, attitudes and beliefs about CRC screening, perceived vulnerability to CRC, and worry about CRC. The main outcome was PAPM stage of adoption of CRC screening based on the ACS preferred guidelines: colonoscopy every 10 years alone or the combination annual FOBT plus sigmoidoscopy every 5 years. RESULTS: 57% were up-to-date with at least one test; 36% were up-to-date with the ACS preferred guidelines; provider recommendation, positive family history of CRC, and positive decisional balance score were significantly associated with higher compared to lower PAPM stages. CONCLUSIONS: The combination of PAPM stage assignment and other factors provides useful information for designing tailored interventions. There are special challenges in developing and interpreting PAPM stage assignments when a guideline offers multiple pathways to adherence and recommends a combination of two tests as a preferred option.

Firearm versus motor vehicle related spinal cord injury: preinjury factors, injury characteristics, and initial outcome comparisons among ethnically diverse groups.

OBJECTIVE: To determine the extent to which individuals with spinal cord injuries caused by firearms differed from those caused by motor vehicle crash (MVC) in terms of selected preinjury factors, injury characteristics and related treatment, and outcomes at discharge from rehabilitation; and to determine the effect of ethnicity on preinjury factors and outcome. DESIGN: Survey including interview of former rehabilitation inpatients and medical records review. SETTING: Model Spinal Cord Injury Care System centered at an urban, public rehabilitation medical center. PARTICIPANTS: Volunteer convenience sample of 164 men who were between the ages of 18 and 35 years at the time of injury and who were injured by firearm or MVC between January 1, 1980 and December 31, 1989. Subjects had completed rehabilitation at a rehabilitation center; they were non-Latino White, African-American, or Latino. Subjects were contacted by mail and telephone. The sample was comprised of 26% of the potential participants; however, differential follow-up rates were highly consistent with distribution of primary characteristics within the population of potential candidates. MAIN OUTCOME MEASURES: The Functional Independence Measure (FIM) and total and rehabilitation lengths of stay were the outcome measures. Groups and outcomes were also compared in terms of preinjury education, employment, and indicators of antisocial behavior, as well as neurological deficit, associated injuries, and surgical treatment. RESULTS: The firearm and MVC groups were different in terms of ethnic distribution. There were no non-Latino Whites in the firearm group and few African-Americans in the MVC group. With the exception of preinjury education, nonparametric and univariate tests showed differences between the firearm and MVC groups in terms of preinjury employment and indicators of antisocial behavior, associated injuries, surgical treatment, neurological deficit, and lengths of stay. Changes in FIM scores, however, were not different between etiologic or ethnic groups. Multiple regression indicated that injury severity accounted for the largest variance in outcomes and that preinjury factors, etiology, and ethnicity did not contribute significantly to the variance in outcome measures. CONCLUSIONS: Although preinjury factors are associated with ethnicity and minorities have higher proportions of SCI caused by firearms, these factors do not significantly influence rehabilitation outcomes at discharge. The primary factors influencing rehabilitation outcomes are related to the deficits, associated physical injuries, and related treatments common to the causes of the injury.

Providing consumers with information about the quality of health plans: the Consumer Assessment of Health Plans demonstration in Washington State.

BACKGROUND: In 1995 the Agency for Health Care Policy and Research began a five-year project, Consumer Assessment of Health Plans (CAHPS), to create instruments to collect data from consumers about their health care experiences, to develop sophisticated methods to convey these data to consumers, and to evaluate the value of these data to consumers who are selecting health plans. Results were obtained from one of the first CAHPS demonstration sites, the Washington State Health Care Authority. METHODS: The survey was distributed in May-June 1997 to 15,885 enrollees in 20 health plans; 8,204 (51.6%) surveys were completed. Survey results were summarized in a report that described the performance of plans, which was distributed to 97,000 enrollees, and reactions to the report were obtained from more than 1,500 individuals. RESULTS: Nearly everyone who was mailed the report said they saw it. A large proportion said they read most or all of it, and most thought the report was easy to understand, contained information needed to rate plans, and was helpful to learning about differences between plans. Those who used the CAHPS performance report were more likely to switch plans and to report that they were confident they had selected the best plan for their situation. DISCUSSION: The study was unique in that it attempted to evaluate whether employees read the performance report, how they reacted to it, and whether reading it influenced their decision to switch plans or their confidence that they had selected a suitable plan. Choosing a new plan probably stimulated more intense scrutiny of the report than not anticipating switching.

Use of a new combined vaccine in pediatric practices.

OBJECTIVE: On December 13, 2002, Pediarix, a combination vaccine that contains diphtheria, tetanus, acellular pertussis; hepatitis B; and inactivated polio vaccines, was licensed by the Food and Drug Administration for use in the primary immunization series. Use of this vaccine decreases the number of injections that children receive when completing their primary immunization series at the 2-, 4-, and 6-month well-child visits. The objective of this study was to determine the factors that influence the use of this combined vaccine in private pediatric practices, with particular attention to the perceived economic impact of Pediarix and actions taken to address this impact within the private pediatric setting. METHODS: A mail survey study was conducted of a random sample of 565 practicing pediatricians that was obtained from the American Medical Association Masterfile. Frequency distributions were developed for all responses, and the vaccine financing policies of the state of practice for each respondent were determined. Chi2 analysis was performed to assess any associations of the predictor variables with the outcome variables of interest, use or consideration of use of the Pediarix vaccine. Logistic regression was used to determine the independent association of the predictor variables with use or consideration of use of Pediarix. Regression models that did and did not include practice ownership as a predictor variable were developed. RESULTS: Response rate was 63% (N = 355). A total of 39% (n = 123) of the respondents' practices were purchasing Pediarix for use with their private patients. An additional 18% (n = 55) were considering purchasing the vaccine. Those who were in practices that were owned by hospitals or health systems were more likely than those who were in solo or group practices to purchase Pediarix for their private patients. Approximately half of the remaining respondents order Pediarix through their state immunization program. Among the 52% of respondents who did not, 23% reported that the vaccine was not yet available through their state program, and 47% stated that they did not want to use different vaccines for their public and private patients. Only 11% believed that Pediarix was not compatible with their other vaccine products. Physicians that currently were purchasing or considering purchasing Pediarix were more likely to be influenced by both parental and provider desire to decrease the number of injections at a single visit and the reduced time for immunization delivery. Fewer than 1% of respondents reported either having experienced or expecting to experience a significant decrease in practice revenue as a result of the use of Pediarix. CONCLUSIONS: Although use of the vaccine results in fewer administration fees for most physicians, the magnitude of the change seemed not to be significant for the majority of respondents or was outweighed by other factors. It also is possible that larger practices or buying cooperatives were able to negotiate discounted rates for Pediarix relative to the constituent products. This may have been a strategy of manufacturers and/or distributors to provide incentive for practices to switch to the combination product. Of note was the appreciation of respondents for the preferences of patients for fewer vaccines and, to a lesser degree, for the decrease in office staff time required to provide vaccination with multiple antigens when using Pediarix. Also, the role of the availability of a given vaccine through the Vaccines for Children program is important in its adoption into practice.

Maximizing worksite survey response rates through community organization strategies and multiple contacts.

BACKGROUND: Worksites are natural settings for health promotion. In many cases, the effectiveness of such interventions is appraised by surveying employees to assess worksite-wide changes in the targeted behavior. Little attention has been paid to increasing worksite survey response rates. One way is to utilize community organization strategies, which involve enlisting the individuals within a group to work together with researchers to affect the social environment. METHODS: Community organization strategies and multiple contacts were used to obtain responses from employees in five worksites involved in a smoking cessation project. Employee Advisory Board members in each worksite reviewed, adapted, and revised the survey distribution method, the messages that accompanied the survey, and the survey content. Three major survey waves were undertaken: a worksite effort, a home mailing (in the pilot worksite only), and a telephone call to nonrespondents. RESULTS: Response rates to a worksite-wide survey in one worksite the first year and four additional worksites the next year yielded 99.3% and 98.4% response rates, respectively. In the pilot worksite, 273 employees were eligible for the survey with 366 eligible employees in the four other worksites. Chi-square or analysis of variance computations were used, as appropriate, to test for differences in characteristics of respondents in the various data collection waves. DISCUSSION: These results suggest that there may be merit in adapting such community organization intervention methods for research applications.

[Fecal incontinence in community-dwelling elderly: findings from a study of prevalence, consultation of physicians, psychosocial aspects and treatment].

OBJECTIVE: To gain insight into the prevalence of faecal incontinence, looking for medical attention, treatment and the impact of faecal incontinence on the quality of life in community-residing men and women of 60 years and over. DESIGN: Enquiry and interview. METHOD: A questionnaire about the incidence of faecal incontinence and the request for help from the family doctor was mailed in 2000 to persons aged 60 and older listed in seven general practices in and round Nijmegen. In an interview with persons with faecal incontinence questions were asked about the need for assistance and the psychosocial consequences of the incontinence. RESULTS: Of the 3887 questionnaires mailed, 3345 were available for analysis, from 1536 males and 1809 females. The prevalence of faecal incontinence was 6%. The male-female distribution was equal and a rise in prevalence was seen with advancing age. One-third of the population discussed the incontinence with their physician, more women (58%) than men (42%). The faecal incontinence had hardly any impact on daily or social activities but the subjects did feel anxiety, shame or frustration. Treatment, if given (14/17), consisted of a prescription for diapers (n = 2) or of referral to an internist for examination of the intestines (n = 4). CONCLUSION: Faecal incontinence occurred in 6% of persons aged 60 or older living independently. Explicit looking for medical attention was not common. There were hardly any male-female differences. The most impact on the quality of life concerned the emotional wellbeing. Treatment had a little effect.

Attitudes of Iowa dental hygienists regarding self-regulation and practice.

PURPOSE: This study investigated Iowa dental hygienists' perceptions about education, practice, and licensure regarding issues related to self-regulation. Furthermore, it was the purpose of the study to determine if these perceptions were statistically related to membership in the American Dental Hygienists' Association (ADHA). METHODS: In October 1992, 150 Iowa dental hygienists were randomly selected to participate in a mail survey. The questionnaire included items on self-regulation, licensure, practice, supervision, delivery systems, and independent practice. Responses were analyzed by frequency distributions and the chi-square statistic. RESULTS: Ninety responses were received, representing 80% of the 112 subjects with valid Iowa addresses, but only 60% of the selected sample. Of the 36 variables analyzed, only two were statistically significantly different by ADHA membership. Thus, data were combined and reported for all respondents. The majority of Iowa dental hygienists (71.6%) believed dental hygiene was pursuing self-regulation to improve quality of care. They wanted more dental hygiene representation on licensure boards and almost 50% wanted separate boards. The majority of respondents favored control of dental hygiene practice and 70% wanted alternatives to the current dental hygiene care delivery system. Most respondents stated general supervision and independent practice would increase access to oral healthcare without increasing patients' risk of health problems. CONCLUSIONS: The majority of Iowa dental hygienists support the dental hygiene profession's goal of self-regulation. ADHA members and nonmembers have similar attitudes and opinions about dental hygiene self-regulation, licensure, delivery systems, and practice.

Adherence to National Cholesterol Education Program Treatment goals in postmenopausal women with heart disease. The Heart and Estrogen/Progestin Replacement Study (HERS). The HERS Research Group.

OBJECTIVES: To determine the proportion of volunteer women with established heart disease who have low-density lipoprotein cholesterol (LDL-C) levels at or below the National Cholesterol Education Program Adult Treatment Panel goals and to determine what factors are associated with levels above goal or not receiving lipid-lowering medication when indicated. DESIGN: Cross-sectional measurement of lipids and lipoproteins, blood pressure, height, weight, and other demographic and cardiovascular risk factors in 2763 postmenopausal women with heart disease. SETTING: At 18 centers throughout the United States, participants were recruited by means of lists of women with coronary heart disease from coronary units and catheterization laboratories, direct mail to age-eligible women, and advertisements. PATIENTS: Mean age of the cohort was 66.7 years (range, 44-79 years) and the distribution by race/ethnicity was 88.7% white, 7.9% African American, 2.0% Hispanic/Latina, 0.8% Asian/Pacific Islander, and 0.7% other. INTERVENTION: We report cross-sectional analysis of the cohort at baseline. OUTCOME MEASURES: We measured the frequency of achieving 1988 and 1993 Adult Treatment Panel treatment goals, and of being on a regimen of lipid-lowering medication. RESULTS: Although 47% of participants were taking a lipid-lowering medication, 63% did not meet the 1988 treatment goal of LDL-C level less than 3.4 mmol/L (130 mg/dL) and 91% did not meet the 1993 goal of LDL-C level less than 2.6 mmol/L (100 mg/dL). Factors independently associated with achieving the earlier goal were use of lipid-lowering medication, marital status, education, body mass index, exercise, hypertension, diabetes, gallbladder disease, and first diagnosis of coronary heart disease after 1990. Failure to use lipid-lowering medication was associated with age, being African American, marital status, body mass index, lack of exercise, alcohol consumption, current smoking, and first diagnosis of coronary heart disease before 1985. CONCLUSION: The majority of women enrolled in the trial had LDL-C levels that significantly exceeded the treatment goals set by the 1988 and 1993 Adult Treatment Panel guidelines. Better implementation of these guidelines among women with coronary disease would be highly desirable.

Frequency of daytime biochemical hypoglycaemia in insulin-treated diabetic patients: relation to daily median blood glucose concentrations.

The frequency and distribution of daytime biochemical hypoglycaemia (capillary blood glucose concentration below 3 mmol/l) was assessed in type 1 diabetic patients on conventional twice daily insulin therapy (n = 79) and on continuous subcutaneous insulin infusion (n = 20). Patients collected and mailed to the hospital blood for seven-point blood glucose profiles. For both treatment regimens the frequency of biochemical hypoglycaemia on individual days was inversely related to the median blood glucose concentration in a curvilinear manner (p less than 0.001). Hypoglycaemia was more frequent pre-prandially than post-prandially (p less than 0.01), and was evenly distributed during the day in patients on continuous subcutaneous insulin infusion. In patients on conventional therapy, however, pre-lunch hypoglycaemia was four times more frequent than pre-breakfast or pre-dinner hypoglycaemia (p less than 0.0001).

Staffing issues at open-heart centers offering both pediatric and adult perfusion service: 1998 survey results.

A survey directed to centers offering both pediatric and adult perfusion services was conducted to determine how pediatric cases were distributed among individual perfusionists in their departments. These centers were also asked what they believed the clinical activity level should be for a perfusionist each year to remain proficient in pediatric cardiopulmonary bypass. The questions were asked via e-mail and then followed up with telephone interviews as necessary. Out of the 100 centers contacted, 45 responded to the survey (43 North American, 2 European). Of the forty-five centers, forty-one provided both pediatric and adult perfusion services. Thirty-two centers (78%) offering adult as well as pediatric perfusion services distributed the pediatric caseload to a select group of perfusionists. Nine centers (22%) distributed the pediatric open-heart caseload to the entire staff. From the respondents, the average minimum number of pediatric cases believed necessary to remain proficient in pediatric perfusion was 42.8 cases annually. Centers having dedicated pediatric perfusionists had a slightly higher annual caseload than did those at non-specialized centers, despite practicing at institutions averaging fewer pediatric open-heart cases annually.
