Abstract
Background Although androgen deprivation therapy (ADT) for prostate cancer demonstrates improved overall and disease-free survival, it is associated with adverse effects such as obesity and metabolic syndrome that increase risk of cardiometabolic disease and diabetes type 2. ADT also leads to fatigue, depression and erectile dysfunction, which reduce quality of life (QoL). Lifestyle modification has shown promise in reducing obesity, metabolic syndrome and diabetes type 2 in other disease types. However, there is a paucity of data regarding the utility of lifestyle modification in men receiving ADT for prostate cancer. Methods The primary aim of the Comprehensive Lifestyle Improvement Program for Prostate Cancer-2 (CLIPP2) is to test the feasibility of conducting a 24-week lifestyle modification intervention in men on ADT for prostate cancer. Additionally, it will also determine the effect of this intervention on weight loss, cardiometabolic markers (secondary aim and markers of interest: serum glucose, insulin resistance, hemoglobin A1C and lipid panel), and QoL (tertiary aim). The intervention will be delivered weekly via telephone for the first 10 weeks and bi-weekly for the remaining 14 weeks. Questionnaires and serum samples will be collected at baseline, week 12, and week 24. Anthropometric measurements will be collected at baseline, week 6, week 12, week 18 and week 24. Results We hypothesize that the CLIPP2 intervention will produce a 7% weight loss that will result in improved markers associated with cardiometabolic disease and type 2 diabetes in the study population. Conclusion Results will provide insight into the role of lifestyle modification in addressing ADT adverse effects as well as provide preliminary data to inform the development of future lifestyle interventions in this area.

Abstract
AIMS To determine the prevalence of pain and its association with glycaemic control, mental health and physical functioning in patients with diabetes. METHODS Cross-sectional data from a multi-site, prospective cohort study of 11 689 participants with diabetes. We analysed the associations of pain severity and interference with glycated haemoglobin (HbA(1c)) measurements and Medical Outcomes Study SF-Mental and Physical Component Summary-12 (MCS-12 and PCS-12) scores. RESULTS Of participants, 57.8% reported moderate to extreme pain and, compared with those without pain, were somewhat older (60.8 vs. 59.9 years, P < 0.001), more obese (body mass index of 32.1 vs. 29.8 kg/m(2), P < 0.001), more likely to report being depressed or anxious (41.3 vs. 16.2%, P < 0.001) and more likely to report fair or poor health (48.5 vs. 23.1%, P < 0.001). Bivariate comparisons demonstrated that patients with extreme pain had higher HbA(1c) than those without pain (8.3 vs. 8.0%, P = 0.001). In multivariable analyses, pain was not associated with HbA(1c) (P = 0.304) but was strongly associated with worse MCS-12 (P < 0.001), PCS-12 (P < 0.001) and depression (P < 0.001). Depression was 1.3 (95% CI: 1.12, 1.96) times more likely in patients with moderate pain and 2.0 (95% CI: 1.56, 2.46) times more likely in patients with extreme pain. CONCLUSIONS Moderate to extreme pain was present in 57.8% of diabetic patients. Pain was strongly associated with poorer mental health and physical functioning, but not worse glycaemic control. Recognizing the high prevalence of pain and its strong association with poorer health-related quality of life may be important to improve the comprehensive management of diabetes.

Abstract
OBJECTIVE To discuss with pharmacists and patients with reactive airways disease their beliefs about pharmaceutical care and the pharmacist's role in health care, obstacles to providing pharmaceutical care in community pharmacies, and strategies to overcome these obstacles. DESIGN Two focus groups of patients, two focus groups of pharmacists. PARTICIPANTS Thirteen patients with reactive airways disease and 11 chain pharmacists. MAIN OUTCOME MEASURES Qualitative reports on the pharmacist's role in health care delivery and obstacles to implementing pharmaceutical care programs. RESULTS Pharmacists wished to provide pharmaceutical care, and patients were supportive of pharmacists' involvement in their health care. Both viewed counseling as an important role for pharmacists and believed that pharmacists should work with patients' physicians. Reported obstacles included lack of time, inadequate privacy, and pharmacists' lack of direct access to patients' physicians. Pharmacists and patients believed pharmacists should have access to patient-specific clinical data. CONCLUSION Focus groups provided valuable information for designing pragmatic pharmaceutical care. The obstacles and possible solutions identified through the discussions represent fertile ground for designing innovative pharmaceutical care programs.

Abstract
A pharmaceutical care program for patients with reactive airways disease (RAD) is described. A pharmaceutical care program for patients with RAD was developed and implemented at 36 CVS pharmacies. The impact on patient outcomes, pharmacist job satisfaction, and other variables is currently being evaluated in a controlled trial with more than 1100 patient enrollees. Guiding the program are the beliefs that pharmacists must have clinically relevant, patient-specific data to provide appropriate care; that pharmacists must have adequate training to provide pharmaceutical care; that the program must be sensitive to organizational barriers, particularly time demands; and that there must be ongoing support for the program. The program has five components: (1) computer display of patient-specific data for patients enrolled in the study, (2) distribution of tailored patient education materials, (3) use of a resource guide to facilitate the implementation of pharmaceutical care, (4) strategies to reinforce and facilitate the program, and (5) pharmacist training. While developed for community pharmacies, the program is applicable to most ambulatory care pharmacy practices. A pharmaceutical care program for patients with RAD was developed for use in community pharmacies.

Abstract
PURPOSE This study was designed to compare the effects of 2 programs that present diet and exercise components in a different sequence. METHODS At an urban YMCA, African American women with type 2 diabetes, aged 30 to 65, were randomly assigned to either 10 weekly sessions about healthy eating followed by 6 weekly sessions about exercise or to the reverse sequence. Sessions consisted of small group discussions and physical activity or food tasting. Primary outcomes were attendance, percent of calories consumed from fat, fruit and vegetable intake, and minutes of exercise per week. Measures were taken at baseline, and 4 and 12 months after the program. RESULTS The only group difference found at the 12-month follow-up was in diastolic blood pressure. Time effects for both groups combined included an increase in minutes of activity, an increase in vegetable intake, and a decrease in percent of calories consumed from fat. CONCLUSIONS This study does not provide definitive evidence of which sequence may be best to bring about behavior change. The effects of sequencing difficult behavioral changes such as diet modification and establishing an exercise habit deserve further study.

Abstract
As one of four work groups for the November 1999 conference on Behavioral Science Research in Diabetes, sponsored by the National Institute on Diabetes and Digestive and Kidney Diseases, the health care delivery work group evaluated the status of research on quality of care, patient-provider interactions, and health care systems' innovations related to improved diabetes outcomes. In addition, we made recommendations for future research. In this article, which was developed and modified at the November conference by experts in health care delivery, diabetes and behavioral science, we summarize the literature on patient-provider interactions, diabetes care and self-management support among underserved and minority populations, and implementation of chronic care management systems for diabetes. We conclude that, although the quality of care provided to the vast majority of diabetic patients is problematic, this is principally not the fault of either individual patients or health care professionals. Rather, it is a systems issue emanating from the acute illness model of care, which still predominates. Examples of proactive population-based chronic care management programs incorporating behavioral principles are discussed. The article concludes by identifying barriers to the establishment of a chronic care model (e.g., lack of supportive policies, understanding of population-based management, and information systems) and priorities for future research in this area needed to overcome these barriers.

Abstract
A survey was mailed to a probability sample of primary care physicians in Indiana to assess their use of and barriers to nutritional therapy for patients with type 2 diabetes. Most (62%) primary care physicians reported referring their type 2 diabetes patients for nutrition counseling, while 38% reported providing counseling themselves. Patient-centered barriers were most frequently cited as reasons for poor effectiveness of nutrition therapy. This differs from previous research that cites system-level factors as barriers.

Abstract
OBJECTIVE The purpose of this study was to assess the validity, reliability, and utility of the Diabetes Empowerment Scale (DES), which is a measure of diabetes-related psychosocial self-efficacy. RESEARCH DESIGN AND METHODS In this study (n = 375), the psychometric properties of the DES were calculated. To establish validity, DES subscales were compared with 2 previously validated subscales of the Diabetes Care Profile (DCP). Factor and item analyses were conducted to develop subscales that were coherent, meaningful, and had an acceptable coefficient alpha. RESULTS The psychometric analyses resulted in a 28-item DES (alpha = 0.96) with 3 subscales: Managing the Psychosocial Aspects of Diabetes (alpha = 0.93), Assessing Dissatisfaction and Readiness To Change (alpha = 0.81), and Setting and Achieving Diabetes Goals (alpha = 0.91). Consistent correlations in the expected direction between DES subscales and DCP subscales provided evidence of concurrent validity. CONCLUSIONS This study provides preliminary evidence that the DES is a valid and reliable measure of diabetes-related psychosocial self-efficacy. The DES should be a useful outcome measure for various educational and psychosocial interventions related to diabetes.

Abstract
OBJECTIVE To describe the practices of Indiana primary care physicians related to diabetic nephropathy screening and management. DESIGN Cross-sectional, observational. SETTING The state of Indiana. PARTICIPANTS Active primary care physicians (defined as general internists, family practitioners, and general practitioners) in Indiana who provided care for diabetic patients at the time of the survey (n = 1,018) MEASUREMENTS AND MAIN RESULTS Practice patterns relevant to microalbuminuria and overt albuminuria screening and management were assessed along two dimensions: the percentage of patients to whom the practices were applied and the frequency with which the practices were performed. Of 1,141 physicians who responded to the survey, 1,018 were eligible for analysis. Eighty-six percent of physicians reported screening more than half of their patients with type 1 diabetes for overt albuminuria, as did 82% of physicians for their patients with type 2 diabetes. Only 17% of physicians indicated performing microalbuminuria testing on more than half of their type 1 patients. Angiotensin-converting enzyme inhibitor agents were used frequently to treat abnormal urinary albumin excretion when hypertension was present, but less often when hypertension was absent. Physician specialty, year of graduation from medical school, practice location, and familiarity with the results of the Diabetes Control and Complications Trial were significant predictors of screening and treatment practice patterns. CONCLUSIONS Primary care physicians report practices that allow them to detect overt albuminuria but not microalbuminuria. Angiotensin-converting enzyme inhibitors are frequently used by physicians who test for microalbuminuria, but efforts to increase the detection of early renal damage are needed so that these agents and other therapeutic strategies may be employed at the earliest opportunity.

Abstract
This article describes the pilot study of an innovative medical school curriculum module that utilizes a modified problem-based learning (PBL) approach to teach medical students about management of diabetes mellitus. The PBL-based curriculum incorporated computer simulations and analysis of videotaped patient encounters in addition to independent study and group discussion. At the conclusion of the study, student knowledge and clinical decision-making skills were evaluated via questionnaires and examinations. Twenty-three students completed the workshop and all evaluation assessments. Students performed well on the case-study examinations (mean score of 3.39 out of 4) but not on the short answer essay examination, which assessed basic knowledge. Students rated the quality and appeal of the activities using Likert-type scales. In general, students perceived the activities as very worthwhile, with reasonable complexity and adequate time devoted to each activity. Students were very positive about the workshop and preceptor; 15 of the 16 items used to rate workshop appeal yielded mean scores greater than 4 (on a scale of 1 to 5, with 5 being the highest). The results of the pilot study suggest future enhancements that would further improve the outcomes of the training.

Abstract
OBJECTIVE To analyze eye care specialist referral patterns for the diabetic patients of primary care physicians. RESEARCH DESIGN AND METHODS In 1993, we conducted a census of primary care physicians to evaluate practice patterns relating to diabetes care in the state of Indiana. Using a logistic regression model and data from this census, we compared 1) physicians' odds of referring type II diabetic patients to an optometrist, as opposed to an ophthalmologist, with those of type I diabetic patients and 2) the referral odds ratios of type II to type I diabetic patients between metropolitan and nonmetropolitan counties. RESULTS Overall, 10% of the physicians in our study most often refer some patients to an optometrist. Physicians are more likely to refer their type II diabetic patients to an optometrist, as opposed to an ophthalmologist, than they are to refer type I diabetic patients, both before and after adjustment for covariates. Physicians who practice in metropolitan counties are 1.55 times more likely to refer their type II diabetic patients than their type I diabetic patients to an optometrist. In nonmetropolitan counties, physicians are 2.5 times more likely to refer their type II diabetic patients to an optometrist. The difference between metropolitan and nonmetropolitan physicians is significant (P = 0.027). CONCLUSIONS Some physicians mostly refer their diabetic patients to optometrists, instead of ophthalmologists, for eye examinations intended to discover early signs of diabetic eye disease. Type II diabetic patients are more likely to be referred to an optometrist, instead of an ophthalmologist, than are type I diabetic patients. In nonmetropolitan areas, the difference in referral patterns becomes even more marked.

Abstract
Sixty-one parents of children with insulin-dependent diabetes mellitus completed modified versions of the Hypoglycemic Fear Survey (HFS) and the Diabetes Quality of Life (DQOL) scale. They also indicated their child's history of hypoglycemic-related seizures or loss of consciousness (SLC) events. Parental HFS scores were significantly greater if their child had ever experienced a SLC event or experienced a SLC event within the past year. Parental HFS scores were positively correlated with general parental worry about their child having diabetes. Adolescent children who experienced a SLC event during the past year reported greater HFS scores, greater general worry about diabetes, and a greater negative impact of having diabetes compared with adolescents with no such history. Despite the greater fear of hypoglycemia in parents and adolescents, there was no significant difference in HbA1 values between children with or without any history of SLC events or children with or without a SLC event within the past year.

Abstract
BACKGROUND Diabetic retinopathy is a costly and prevalent complication of diabetes mellitus. OBJECTIVE To assess primary care physicians' self-reported practice patterns for the screening and detection of diabetic retinopathy relative to published guidelines. PARTICIPANTS AND METHODS All primary care physicians (defined as general internists, family practitioners, and general practitioners) in Indiana were identified and surveyed using a mailed questionnaire. Of 2390 physicians, 1508 (63%) responded and were determined to be eligible. Of these 1508 physicians, 1058 (70%) completed all or some of the eye care-related questions. For each eye care practice, physicians were asked to specify the proportion of patients to which the practice was applied and the frequency (eg, every 3 months) with which the behavior was performed, if appropriate. Physicians were also asked to distinguish between patients with type I (insulin-dependent) and type II (non-insulin-dependent) diabetes mellitus for each practice behavior. RESULTS Physicians' responses were classified as "high," "moderate," or "low" based on the American Diabetes Association guidelines. Forty-five percent of the physicians' responses were classified as high for referring all of their patients with type I diabetes mellitus to an eye care specialist annually as were 35% of the physicians' responses for referring their patients with type II diabetes mellitus. Fewer physicians reported high levels of routine in-office funduscopic examination. No relationship was found between the extent to which physicians performed an in-office funduscopic examination and patterns of referral to eye care specialists. Logistic regression analysis suggested that recent graduates and general internists are most likely to report behavior that is considered high (P < .05). CONCLUSION The diabetic retinopathy-related practice patterns of primary care physicians in Indiana differ significantly from published guidelines.

Abstract
Insulin dependent diabetes mellitus (IDDM) poses a large social and economic burden on society. There are now methods for identifying persons at risk for IDDM and increasing evidence suggest that it may be possible to delay or even prevent the clinical presentation of the disease. This raises the question of whether a prevention program for IDDM should be initiated through public health channels. Review of the literature suggests that in spite of the considerable societal burden associated with diabetes, there are currently no broadly applicable, effective methods for identifying persons at increased risk of developing IDDM nor are there proven strategies for its prevention when risk is established. Until strategies to identify persons at risk of IDDM and methods to prevent the onset of disease are established, a better use of limited resources may be the secondary and tertiary prevention of complications of the disease.

Abstract
The purpose of this study was to evaluate the efficacy of using a telecommunication system to assist in the outpatient management of pediatric patients with insulin-dependent diabetes. Metabolic control, patients' psychosocial status, family functioning, perceived quality of life, patterns of parental/child responsibility for daily diabetes maintenance, and nursing time-on-task were evaluated. One hundred six pediatric patients (mean age = 13.3 years) were randomly assigned to an experimental or control outpatient clinic for 1 year. Experimental subjects transmitted self-monitoring blood glucose data by modem to the hospital every 2 weeks. Transmitted data were reviewed by nurse practitioners who telephoned subjects to discuss regimen adjustments. Control subjects received standard care with regimen adjustments made by physicians. There were no significant between-group differences for metabolic control, rates of hospitalization or emergency-room visits, psychological status, general family functioning, quality of life, or parent-child responsibility. A significant decrease was noted in nursing time-on-task for experimental subjects.

Abstract
Diabetic retinopathy is the leading cause of new blindness in the 20 to 74-age group in the United States. The American Academy of Ophthalmology (AAO) and American Diabetes Association (ADA) have recommended guidelines for eye examination to assist primary care physicians in managing these patients. The purpose of this study is to investigate the patterns of diabetic eye care offered by primary care physicians in the State of Indiana. A survey questionnaire was sent to 1279 primary care physicians in central Indiana. Of those surveyed, 259 (20%) responded. Thirty-five percent of respondents stated that they never refer patients for ocular examination while 26% refer all patients. The remainder refer on a case-by-case basis. Patients who are not referred have their fundus examined only 70% of the time by the primary care physician and 96% of these examinations are performed with an undilated pupil. When referred, 20% of Type I patients are referred at the time of diagnosis and 50% by one year. Of the Type II patients, only 2% are referred at the time of diagnosis and 70% by one year. Ophthalmologists receive 75% of the referrals while optometrists receive 20%. Our results show that a significant number of primary care physicians in the State of Indiana do not follow the recommended guidelines set forth for diabetic eye care.

Abstract
PURPOSE Family practice (FP), General Practice (GP) and obstetrics-gynecology (OB/GYN) physicians were surveyed to determine whether they routinely referred pregnant patients with diabetes to an ophthalmologist, looked into the patient's eyes to screen for retinopathy, and dilated the eyes for fundi examination. METHODS Hospitals providing obstetrical services were contacted to identify primary-care physicians. Physicians identified as having obstetrical privileges were surveyed by mail to determine if they were actively providing obstetrical care. Physicians who provided both obstetrical and diabetes care were mailed a survey. RESULTS Of 668 physicians surveyed, 429 responded: 224 FPS, 184 OB/GYNS and 21 GPS. A relatively small percentage (27%) of physicians in both groups routinely refer all of their pregnant patients with pre-existing diabetes to an ophthalmologist. Family practice physicians were more likely to perform an eye exam to screen for retinopathy in patients with both pre-existing and gestational diabetes than OB/GYNS (p < .0005). Only 11% of FPS and no OB/GYNS reported that they dilated the eyes when performing a fundus examination (p = .04). CONCLUSION The physicians surveyed under-utilize recommended strategies for eye care of pregnant women with pre-existing diabetes. Based upon these results, we call for a recommitment to partnership of primary-care physicians and ophthalmologists in the detection and treatment of diabetic retinopathy during pregnancy.

Abstract
OBJECTIVE This study compared the performance of a new device that uses an IA to measure HbA1c in 9 min with a 1-microliter capillary blood sample with AC and CE methods in both nondiabetic and diabetic pediatric patients. RESEARCH DESIGN AND METHODS Two hundred seven pediatric subjects (103 nondiabetic, 104 with insulin-dependent diabetes mellitus) had HbA1c measured with the IA method and compared with total GHb values determined by AC and HbA1 by the CE method with the same whole-blood capillary aliquot. Glucose values were also obtained from the same blood samples. RESULTS Correlations and regression analyses show excellent correspondence between the three assays. The correlation between the AC and CE methods is 0.98 (P less than 0.001) with a slope of 1.615 +/- 0.0125 and intercept of 4.00 +/- 0.20. The correlation between the IA and AC methods is 0.99 (P less than 0.001) with a slope of 0.608 +/- 0.007 and intercept of 1.326 +/- 0.066. The correlation between the IA and CE methods is 0.97 (P less than 0.001), with a slope of 0.983 +/- 0.018 and intercept of 1.122 +/- 0.153. The average difference and average percentage difference between methods were also significant (P less than 0.001), reflecting the differences in GHb components measured. There was a significant correlation (P less than 0.001) between each method and glucose values (IA r = 0.72, AC r = 0.70, CE r = 0.73). Within-run precision for IA ranged from 1.7 to 3.5% and between-run precision 2.7 to 4.1%. CONCLUSIONS Study results suggest that the IA method gives extremely accurate and reliable values over the clinical range of interest. The instrument is small, portable, easy to use, and provides information within 9 min for both physicians and patients.

Abstract
Parental worries, specific to having a child with diabetes, have been associated with poor diabetes control. This study addressed three questions relating to this issue: Does parental worry affect the metabolic control of the child with IDDM? What specific aspects of diabetes are the most worrisome to parents? Do these concerns change with the child's age and disease duration? Parents of 93 children with IDDM were given a modified version of the Diabetes Quality of Life measure to evaluate diabetes-specific worries. No correlation was found between parental worry and the child's metabolic control. Parents of younger children expressed the largest amount of worry, yet the kinds of things that parents were most concerned about were the same, regardless of age or duration of the child's disease.

Abstract
OBJECTIVE To ascertain the strategies used by primary-care physicians for treating pregestational and gestational diabetes mellitus (GDM) during pregnancy, because many women with pregnancies complicated by these types of diabetes are treated by physicians who have no special training in intensive diabetes management. RESEARCH DESIGN AND METHODS Two hundred twenty-four family-practice (FP) physicians and 184 obstetrics/gynecology (OB/GYN) physicians were surveyed by mail. RESULTS When compared with OB/GYNs, FPs were less likely to screen all pregnant women for GDM (P = 0.03), use multiple-injection insulin regimens (P = 0.004) or self-monitoring of blood glucose (SMBG) (P = 0.01) for Pre-GDM patients, and refer these patients to a specialist for medical (P = 0.01) or ophthalmologic (P less than 0.001) care. FPs were more likely to implement insulin therapy (P = 0.003), SMBG (P = 0.02), and examine eyes for retinopathy (P less than 0.001) when treating gestational patients. CONCLUSIONS These data show that there are considerable discrepancies between the strategies used by FPs and OB/GYNs and also suggest that physicians in both groups are under-utilizing recommended treatment strategies described in publications targeted specifically to primary-care physicians. Increased exposure to and dissemination of guidelines for diabetes management and additional medical school and postgraduate education programs are recommended as methods to improve utilization of these strategies.

Abstract
The extent to which a sample of community based, primary care physicians follow current standards of care for the treatment of non-obese, insulin-requiring patients as defined and recently published by the American Diabetes Association (ADA) was studied. A total of 212 physicians responded with 191 indicating that they treat one or more non-obese, insulin-requiring patients. Of this sample, 97% used multiple injection, mixed insulin regimens. However, over 70% also used single injection regimens. Whereas 94% prescribed self-monitoring blood glucose (SMBG), only 31% did so for more than 75% of their patients and 37% did so for less than 50%. Twenty-five percent of respondents did not obtain HbA1 values on their patients. For respondents who do collect HbA1, only 28% did so for over 75% of their patients and 30% for less than 50%. Physicians with fewer patients were more likely to prescribe single injection insulin regimens (P = .02). Recent graduates from medical school also used HbA1's more frequently than earlier graduates (p = .001). These data suggest that while care practices recommended by the ADA are being implemented by primary care physicians, they are significantly underutilized.

Abstract
In the Diabetes Control and Complication Trial (DCCT), a Diabetes Quality of Life (DQOL) measure was developed to assess the psychosocial impact of intensified regimens. Its applicability for use with children and adolescents was limited by the exclusion criteria of the DCCT. In this study, the DQOL was modified for specific use in young diabetes populations. The result is an instrument composed of three intercorrelated scales--a Diabetes Life Satisfaction scale, a Disease Impact scale, and a Disease-Related Worries scale--with satisfactory levels of reliability. While the scale variances were independent of glycosylated hemoglobin values, they were related to adolescents' perception of their general health status. Self-perceived quality of life related to diabetes management is an important alternative outcome for diabetes education programs.

Abstract
We compared glycosylated hemoglobin (GHb) determined from capillary blood samples on paper strips with a standard microcolumn technique in a cross-sectional observational study with laboratories blinded to duplicate samples. Both the standard and the filter strip laboratories were provided with 80 uniquely identified blood samples from 40 individuals. Each laboratory ran duplicate analyses on each sample, yielding 160 GHb values. The within-laboratory correlations between blinded duplicates were 0.98 for the standard (microcolumn technique) and 0.94 for the filter paper (affinity technique) laboratories. The between-laboratory correlations ranged from 0.69 to 0.77. When classifying patients by quartile of glycemic control, the laboratories agreed on 60% of the patients. In an effort to identify sources of between-laboratory variability, varying quantities of blood were applied to strips and reanalyzed. Five microliter drops always yielded inflated estimates of GHb. These data suggest that the estimates of GHb obtained from mail-in paper strips, although internally consistent, differ in important ways from standard laboratory values, reemphasizing the need for caution in the interpretation of interlaboratory and intermethod comparisons.

Abstract
General pediatricians provide comprehensive care for many children with insulin-dependent diabetes mellitus. To assess and improve our ambulatory training program, we first evaluated diabetes-specific care behaviors by residents in their continuity clinics and then introduced a structured visit encounter form. Based on established guidelines provided to the residents, a chart audit indicated appropriate measurement of glycosylated hemoglobin 40% of the time, cholesterol 90% of the time, urine protein 50% of the time, and thyroxine 66.7% of the time. Height was plotted 23% of the time, blood pressure was noted 66% of the time, and ophthalmologic referrals were documented 60% of the time. Requests for assistance from nonphysician members of a multidisciplinary diabetes team were minimal. After introduction of the structured visit encounter form, care behaviors did not improve. New training approaches to prepare general pediatric residents to provide excellent diabetes care are needed.

Abstract
Many pediatric diabetes patients are cared for by community-based pediatricians. Training for pediatricians in optimal diabetes care should be based on both the recommendations of pediatric endocrinologists regarding optimal care and the practices of general pediatricians. Pediatric endocrinologists, general pediatricians, and pediatric residency coordinators were surveyed to assess the consonance of current recommendations, practices, and training in pediatric diabetes care. Not surprisingly, pediatric endocrinologists recommended more subspecialty care than pediatricians reported practicing. A major difference between endocrinologists and pediatricians emerged in the area of psychosocial support. A total of 85% of endocrinologists answered that there should be a mental health diabetes team member, but only 37% of pediatricians reported often or sometimes working with one to develop care plans. Pediatricians who provide complete diabetes care for most of their patients measure frequent glycosylated hemoglobin levels, obtain yearly lipid measurements marginally less often, and use urinary glucose measurements more often than recommended by pediatric endocrinologists. According to the descriptions of most pediatric residency training programs, multidisciplinary teams include a pediatrician, an endocrinologist, and a dietician. However, 25% do not include a social worker or nurse and 70% do not include a psychologist. Although most training programs operate on the assumption that their trainees will ultimately share responsibility with a subspecialist for diabetes care, in 26% of programs residents saw no diabetics in their continuity clinics. Most residents do not participate in providing diabetes education.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The Glucometer M Diabetes Management System includes a glucose-reflectance meter with memory that can interface with a microcomputer for data manipulation and analysis. We evaluated the system in a short-term randomized control trial to determine its impact on metabolic control, self-monitoring of blood glucose (SMBG) testing behaviors, regimen self-adjustment, understanding of insulin-dependent diabetes mellitus (IDDM) treatment, attitudes about SMBG, and perceived quality of patient-physician interaction. Twenty-nine adolescent subjects (experimental) with IDDM were randomly assigned the Glucometer M system for 4 mo. Twenty-eight control subjects used meters without memory. All subjects returned twice to the clinic at 2-mo intervals during the study. At clinic visits, both groups reviewed their SMBG data with their physician. Reviews on experimental subjects were conducted with computer-generated data formats. Control subject reviews used traditional logbooks. Both groups showed a significant drop in glycosylated hemoglobin during the study period (P less than .001); however, there were no between-group differences. There were also no differences in SMBG testing behavior or self-reported regimen self-adjustment between groups or within groups compared with baseline. Compared with control subjects, experimental subjects indicated a significant increase in self-reported understanding of IDDM treatment (P = .002), perceived importance of testing (P = .006), and the quality of interaction with their physician (P less than .001). These data suggest that use of computer-assisted SMBG systems in the outpatient setting does not improve metabolic control over 4 mo. It may, however, contribute to improving communication between the patient and health-care providers.

Abstract
Improving metabolic outcomes in children and adolescents with IDDM who are in chronically poor metabolic control is one of the most difficult tasks confronting health care providers. These patients have clinical histories characterized by recurrent episodes of diabetic ketoacidosis and the persistance of acute disease symptoms. Complex psychosocial factors play a critical role in the genesis of chronic poor control, and patients are often resistant to standard interventions. To guide treatment of these difficult patients, we have developed a stepwise intervention program that addresses psycho social issues and provides strategies for improving metabolic control. The steps include documentation of patient response to insulin and the correction of educational deficiencies, defining and renegotiating the family care role, confronting families' inappropriate perceptions of care, and legal interventions. Previous evaluation has shown that appli cation of this approach can nearly eliminate recurrent episodes of diabetic ketoacidosis.

Abstract
In this project we investigated the impact of a 12-week at-home aerobic fitness program on aerobic capacity and metabolic control of ten adolescents (four girls and six boys 12 to 14 years of age) with insulin-dependent diabetes mellitus. The adolescents had no prior experience with exercise training. The 45-minute program, designed by a physical therapist, consisted of a stretching, calisthenics, and "cool-down" routine set to popular music. It was taught to the youngsters in group sessions. Each adolescent was given audio- and videocassettes of the routine for home use that emphasized self-motivation in maintaining training. The youngsters were asked to exercise three times per week and were also taught how to adjust their insulin and diet for exercise. Aerobic fitness was determined by maximal oxygen uptake following a vigorous, continuous progressive cycling test; metabolic control was measured by glycosylated hemoglobin values. All of the adolescents reported greater than 85% completion of the program. The youngsters displayed a correspondingly significant increase in aerobic fitness as measured by maximal oxygen uptake: 40.39 +/- 8.87 v 44.86 +/- 12.89 mL/kg/min. Glycosylated hemoglobin levels (mean +/- SD) for the entire group were significantly reduced after the program (11.41 +/- 4.47% v 10.01 +/- 3.21%). Results of this study indicate that nonathletic adolescents with insulin-dependent diabetes mellitus can engage in self-motivated exercise training at home. If properly designed, such programs can improve aerobic fitness and may contribute to improvement in diabetes control.

Abstract
An arcade-style game, Betakid, was developed to provide diabetic children an opportunity to practice and evaluate skills in food and insulin dose selection. The user participates in the events through displays of text and graphics, occasionally accompanied by music. Choices are made concerning insulin dose, diet, and exercise. A displayed score indicates the appropriateness of the user's actions. Remediation is available after each decision. During the design and initial evaluation of Betakid, a number of lessons were learned about the application of computer-based simluations to diabetes education and care. The approach that was followed in developing Betakid, a summary of the characteristics of the simulation, and a list of suggestions for efficiently developing this type of project are presented.

Abstract
The medical and psychosocial findings concerning 15 adolescents with poorly controlled diabetes referred to a tertiary center are reviewed. While referring physicians usually attributed poor metabolic control to an unusual idiosyncratic pathophysiologic aspect of diabetes, all patients were managed by conventional treatment regimens. Psychosocial problems, including excessive school absence, depression, and social isolation were frequent in this population, and in eight families emotional factors appeared to contribute to the development and persistence of poor metabolic control. Eight patients accepted psychosocial intervention consisting of individual, family, and/or group counseling. Not one of the patients has been hospitalized for ketoacidosis in the subsequent 12-18-mo period, and their psychosocial functioning as adolescents is improved. Hemoglobin A1c levels remained elevated. Psychosocial factors in adolescents experiencing poor metabolic control should be addressed.

Abstract
Seven children and adolescents (aged 8 to 23 years, mean 16 years) with poorly controlled insulin-dependent diabetes mellitus were evaluated with a glucose-controlled insulin infusion system (GCIIS) to determine whether its use could help define appropriate long-term insulin treatment regimens and increase patient understanding and compliance with such regimens. The GCIIS-derived insulin regimen was characterized by a mean insulin requirement of 1.0 +/- 0.1 units/kg/day, with 55% of the total insulin dose given in the morning and 45% in the evening. Forty-eight percent of the total insulin was short acting. Both clinical and biochemical indices of metabolic control (HbA1c levels) improved after insulin dose readjustment based on GCIIS data. The continuous documentation of blood glucose levels provided by the GCIIS was valuable in educating patients about the interrelationship between insulin, exercise, and diet. Using GCIIS data, patients were taught to apply the new regimen flexibly to variations in activity and diet. Thus, the GCIIS can aid in the management of selected children and adolescents with insulin-dependent diabetes millitus. Insulin patterns derived from its use suggest that a flexible, twice daily regimen characterized by nearly equal proportions of short- and intermediate-acting preparations may be beneficial for other pediatric patients.
