Compliance with recommended follow-up after percutaneous breast core biopsy.

OBJECTIVE: The purpose of this study was to use information from an established patient tracking system to evaluate patient outcome and assess patient compliance with recommended follow-up after percutaneous breast core biopsy. MATERIALS AND METHODS: All breast core biopsies performed from January 1994 through February 14, 1996, that used stereotaxic or sonographic guidance were reviewed. Clinical, imaging, and pathologic findings were correlated with patient outcomes established by recommended surgical and nonsurgical follow-up. RESULTS: Of 160 core biopsies in 153 women, 30 biopsies were performed on the basis of clinical complaints. One hundred thirty lesions were detected by mammography or sonography or both. Of the 70 lesions recommended for surgical excision, 52 (74%) had documented surgical outcomes. Mammographic surveillance was recommended for 90 lesions, of which 10 (11%) had resolved at the time of this study, 49 (54%) were on track toward 3-year lesion stability, 21 (23%) were being followed up elsewhere, four (4%) were lost to physicians, and six (7%) were lost to follow-up for other reasons. CONCLUSION: Known compliance with follow-up recommendations among these 153 patients who underwent breast core biopsy was higher for patients receiving surgical recommendation (74%) than for patients receiving imaging surveillance recommendation (54%). Problems tracking patients were caused both by loss of patients to follow-up and by incomplete reporting from referring physicians.

Inside guidelines: comparative analysis of recommendations and evidence in diabetes guidelines from 13 countries.

OBJECTIVE: To compare guidelines on diabetes from different countries in order to examine whether differences in recommendations could be explained by use of different research evidence. RESEARCH DESIGN AND METHODS: We analyzed 15 clinical guidelines on type 2 diabetes from 13 countries using qualitative methods to compare the recommendations and bibliometric methods to measure the extent of overlap in citations used by different guidelines. A further qualitative analysis of recommendations and cited evidence for two specific issues in diabetes care explored the apparent discrepancy between recommendations and evidence. RESULTS: The recommendations made in the guidelines were in agreement about the general management of type 2 diabetes, with some important differences in treatment details. There was little overlap in evidence cited by the guidelines, with 18% (185/1,033) of citations shared with any other guideline, and only 10 studies (1%) appearing in six or more guidelines. The measurable overlap in evidence between guidelines increases if multiple publications from the same study and the use of reviews are taken into account. Research originating from the U.S. predominated (40% of citations); however, nearly all (11/12) guidelines were significantly more likely to cite evidence originating from their own countries. CONCLUSIONS: Despite the variation in cited evidence and preferential citation of evidence from a guideline's country of origin, we found a high degree of international consensus in recommendations made for the clinical care of type 2 diabetes. The influence of professional bodies such as the American Diabetes Association may be an important factor in explaining international consensus. Globalization of recommended management of diabetes is not a simple consequence of the globalization of research evidence.

Achievement of American Diabetes Association clinical practice recommendations among U.S. adults with diabetes, 1999-2002: the National Health and Nutrition Examination Survey.

OBJECTIVE: To estimate the proportion of U.S. adults with diabetes who meet American Diabetes Association (ADA) clinical practice recommendations. RESEARCH DESIGN AND METHODS: Using data from the 1999-2002 National Health and Nutrition Examination Survey, 998 adults aged >/=18 years with self-reported diabetes were identified. The proportion of adults with diabetes meeting ADA recommendations for HbA(1c) (A1C), HDL cholesterol, LDL cholesterol, triglycerides, blood pressure, renal function, nutrient intake, smoking, pneumococcal vaccination, and physical activity was estimated. RESULTS: Among U.S. adults with diabetes in 1999-2002, 49.8% had A1C <7%; 27.4, 36.0, and 65.0% were classified as low risk for HDL cholesterol, LDL cholesterol, and triglycerides, respectively. Nearly 40% met blood pressure recommendations, 66% had normal renal function, and daily nutrient recommendations for protein, saturated fat, unsaturated fat, and fiber were met by 64.0, 48.3, 28.3, and 18.3%, respectively. Although >81% of the sample reported not smoking at the time of the exam, only 38.2% reported ever having had a pneumococcal immunization, and 28.2% reported getting the recommended level of physical activity. Race, age, duration of diabetes, and education affected achievement of ADA recommendations. CONCLUSIONS: Achievement of ADA clinical practice recommendations is far from adequate in U.S. adults with diabetes.

Consensus recommendations on diagnostic testing for the detection of paratuberculosis in cattle in the United States.

The report provided here contains a simplified set of diagnostic testing recommendations. These recommendations were developed on the basis of research funded by the USDA-Animal and Plant Health Inspection Service-Veterinary Services through a cooperative agreement. The report is intended to provide simple, practical, cost-effective consensus testing recommendations for cattle herds that are not enrolled in the US Test-Negative Program. The information has been reviewed by paratuberculosis (Johne's disease) experts at the USDA and academic centers as well as stakeholders in various segments of the cattle industry. The recommendations were accepted by the National Johne's Working Group and Johne's Disease Committee of the US Animal Health Association during their annual meetings in October 2006. The report is intended to aid veterinarians who work with cattle producers in the United States. The recommendations are based on information available up to October 2006. There is a paucity of large-scale, high-quality studies of multiple tests conducted on samples obtained from the same cattle. It is understood that there may be special circumstances that require deviation from these recommendations. Furthermore, as new information becomes available and assays are improved and their accuracy is critically evaluated, changes to these recommendations may be necessary.

[Italian consensus on EULAR recommendations 2005 for the management of hip osteoarthritis].

The recommendations for the management of osteoarthritis (OA) of the hip were proposed by EULAR in 2005. Among the most important objectives of the expert charged to provide these recommendations were their wide dissemination and implementation. Thus, the information generated can be used by each individual country to produce their own set of management guidelines and algorithms for treatment in primary care. According with that previously executed for the EU-LAR recommendation 2003 for the knee, the Italian Society of Rheumatology (SIR) has organised a Consensus on the EULAR recommendations 2005 for the management of hip OA. To obtain an acceptability as large as possible, the group of experts was composed by many physicians interested in the management of hip OA, including Orthopaedics, Rheumatologists, Physiatrists, and General Practitioners. Main aim of the Consensus was to analyse the acceptability and applicability of the recommendations according to own experience and local situations in the Italy. The results of this Consensus have demonstrated that a large majority of the EULAR recommendations are endorsed by the Italian experts. Furthermore, the final document of the Italian Consensus clearly indicated the need that the specialists involved in the management of hip OA strongly encourage the dissemination of the EULAR 2005 recommendations also in Italy.

Are recommendations about routine antenatal care in Australia consistent and evidence-based?

OBJECTIVE: To describe the variability and evidence base of recommendations in Australian protocols and national policies about six aspects of routine antenatal care. DESIGN: Comparison of recommendations from local protocols, national guidelines and research about number of visits, screening for gestational diabetes (GDM), syphilis, hepatitis C (HCV), and HIV, and advice on smoking cessation. SETTING: Australian public hospitals with more than 200 births/year, some smaller hospitals in each State and Territory, and all Divisions of General Practice were contacted in 1999 and 2000. We reviewed 107 protocols, which included 80% of those requested from hospitals and 92% of those requested from Divisions. MAIN OUTCOME MEASURES: Frequency and consistency of recommendations. RESULTS: Recommendations about syphilis testing were notable in demonstrating consistency between local protocols, national policies and research evidence. Most protocols recommended screening for GDM, despite lack of good evidence of its effectiveness in improving outcomes. Specific approaches to screening for GDM varied widely. Coverage and specific recommendations about testing for HIV and HCV were also highly variable. Smoking-cessation information and advice was rarely included, despite good evidence of the effectiveness of interventions in improving outcomes. No national policies about the number of routine visits and smoking cessation could be identified. There were inconsistent national policies for both HIV and GDM screening. CONCLUSIONS: Antenatal care recommended in protocols used in Australia varies, and is not always consistent with national policies or research evidence. Producing and disseminating systematic reviews of research evidence and national guidelines might reduce this variability and improve the quality of Australian antenatal care.

Association of body mass index to meeting physical activity recommendations.

OBJECTIVE: To investigate the association between BMI and physical activity based on the CDC-ACSM recommendation and a more demanding standard consistent with the IOM recommendation. METHODS: A random-digit-dialed survey (n=1810) used 2001 BRFSS questions to measure physical activity. RESULTS: Data revealed a monotonic association between BMI and physical activity level. Lower odds of meeting both recommendations were associated with higher BMI. The proportion meeting the CDC-ACSM recommendation was at least 3 times that of persons meeting the IOM-based recommendation. CONCLUSIONS: Meeting either recommendation was associated with BMI; however, a larger proportion of persons were meeting the less demanding CDC-ACSM recommendation.

Recommendations on population screening for colorectal cancer in New Zealand. Members of the National Health Committee Working Party on Population Screening for Colorectal Cancer.

The National Advisory Committee on Health and Disability invited a working party to make recommendations on population screening for colorectal cancer in New Zealand. Recent results from randomised controlled trials of screening with guaiac faecal occult blood tests have provided evidence that population screening could reduce mortality from colorectal cancer. However, given the modest potential level of benefit, the considerable commitment of health sector resources, and the small but real potential for harm, the working party does not recommend population screening for colorectal cancer with faecal occult blood tests in New Zealand. The working party does nto recommend pilot colorectal cancer screening programmes in New Zealand because pilot programmes cannot address the issues of concern: the modest potential benefit and the small, but real, potential for harm. The working party does not recommend faecal occult blood testing as a screening test for colorectal cancer in average-risk individuals outside a population screening programme. Those requesting screening by faecal occult blood test should be given information about the potential risks and benefits. Follow-up bowel investigations in the public health system cannot be guaranteed without an increased allocation of resources. As there is yet no evidence from randomised controlled trials that screening with flexible sigmoidoscopy, colonoscopy or double-contrast barium enema produces a reduction in colorectal cancer mortality, the working party does not recommend population screening with these modalities. Wider consultation and further consideration should be undertaken to develop appropriate advice on surveillance recommendations for groups identified to be at increased risk of colorectal cancer. These decisions should be reviewed as evidence of benefit from new types of faecal occult blood test and other screening modalities becomes available. The working party recognises that colorectal cancer is an important cause of morbidity and mortality and recommends that New Zealand participate in international research in this area.

The economic impact of clinical pharmacists' unsolicited recommendations.

Clinical pharmacists in a 580-bed teaching hospital reported all targeted recommendations that occurred during a 5-month evaluation period. Five types of clinical recommendations were identified: (1) to start drug therapy, (2) to stop drug therapy, (3) to increase drug dose, (4) to decrease drug dose, and (5) to suggest alternative drug therapy. Two thousand sixty-four unsolicited, accepted recommendations were submitted to the investigator by approximately eight holders of full-time equivalent positions dedicated to clinical pharmacy services during the evaluation period. Three hundred forty-four recommendations were selected (every sixth submitted recommendation) and evaluated for their economic impact. The costs of drugs, monitoring, and treatment for the drug regimens were compared before and after each recommendation. Three classes of drugs (antineoplastics, anti-infectives, and gastrointestinal agents) contributed more than 90% of the economic impact. The net economic impact of the evaluated recommendations was a cost saving of $4636.06; this extrapolated to a net cost saving of $34.10 per pharmacist-day.

Lifestyle modifications to prevent and control hypertension. 1. Methods and an overview of the Canadian recommendations. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations for health care professionals on lifestyle changes to prevent and control hypertension in otherwise healthy adults (except pregnant women). OPTIONS: For people at risk for hypertension, there are a number of lifestyle options that may avert the condition--maintaining a healthy body weight, moderating consumption of alcohol, exercising, reducing sodium intake, altering intake of calcium, magnesium and potassium, and reducing stress. Following these options will maintain or reduce the risk of hypertension. For people who already have hypertension, the options for controlling the condition are lifestyle modification, antihypertensive medications or a combination of these options; with no treatment, these people remain at risk for the complications of hypertension. OUTCOMES: The health outcomes considered were changes in blood pressure and in morbidity and mortality rates. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the period January 1996 to September 1996 for each of the interventions studied. Reference lists were scanned, experts were polled, and the personal files of the authors were used to identify other studies. All relevant articles were reviewed, classified according to study design and graded according to level of evidence. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: Lifestyle modification by means of weight loss (or maintenance of healthy body weight), regular exercise and low alcohol consumption will reduce the blood pressure of appropriately selected normotensive and hypertensive people. Sodium restriction and stress management will reduce the blood pressure of appropriately selected hypertensive patients. The side effects of these therapies are few, and the indirect benefits are well known. There are certainly costs associated with lifestyle modification, but they were not measured in the studies reviewed. Supplementing the diet with potassium, calcium and magnesium has not been associated with a clinically important reduction in blood pressure in people consuming a healthy diet. RECOMMENDATIONS: (1) It is recommended that health care professionals determine the body mass index (weight in kilograms/[height in metres]2) and alcohol consumption of all adult patients and assess sodium consumption and stress levels in all hypertensive patients. (2) To reduce blood pressure in the population at large, it is recommended that Canadians attain and maintain a healthy body mass index. For those who choose to drink alcohol intake should be limited to 2 or fewer standard drinks per day (maximum of 14/week for men and 9/week for women). Adults should exercise regularly. (3) To reduce blood pressure in hypertensive patients, individualized therapy is recommended. This therapy should emphasize weight loss for overweight patients, abstinence from or moderation in alcohol intake, regular exercise, restriction of sodium intake and, in appropriate circumstances, individualized cognitive behaviour modification to reduce the negative effects of stress. VALIDATION: The recommendations were reviewed by all of the sponsoring organizations and by participants in a satellite symposium of the fourth international Conference on Preventive Cardiology. They are similar to those of the World Hypertension League and the Joint National committee, with the exception of the recommendations on stress management, which are based on new information. They have not been clinically tested. SPONSORS: The Canadian Hypertension Society, the Canadian Coalition for High Blood Pressure Prevention and Control, the Laboratory Centre for Disease Control at health Canada, and the Heart and Stroke Foundation of Canada.

Physicians' recommendations for patients who undergo noncardiac surgery.

OBJECTIVE: To investigate how consulting physicians attempt to modify perioperative cardiac risk for patients who undergo noncardiac surgery by comparing the preoperative cardiac recommendations of consulting physicians in 2 university centres. DESIGN: Retrospective cross-sectional analysis. SETTING: Five hospitals affiliated with 2 Canadian universities. PATIENTS: Three hundred and eight preoperative consultations were evaluated in 297 patients who were 40 years of age or older and scheduled for noncardiac surgery. OUTCOME MEASURES: Cardiac drug recommendations at the preoperative consultation [corrected]; overall recommendations and practice variation between the 2 centres. RESULTS: The greatest changes in drug management suggested by consultants were the initiation of nitrates in 13% of the patients and a decrease in acetylsalicylic acid administration from 27% to 17%. Centre A physicians recommended adding an angiotensin-converting enzyme inhibitor 11% of the time, whereas centre B physicians recommended such an inhibitor in only 1% of the patients (p = 0.001). In patients taking acetylsalicylic acid at the preoperative consultation, Centres A and B physicians recommended withholding the drug 47% and 22% of the time, respectively (p = 0.03). These differences persisted between the 2 centres after controlling for physician estimates of risk. CONCLUSIONS: Consultants frequently recommended perioperative changes in the use of cardiac medications, and there were differences in practice patterns between the 2 centres. These differences may be affecting patient outcomes and highlight the need for randomized clinical trials to determine the impact of perioperative drug administration on bleeding, myocardial infarction and death.

Comparison of patients hemodialyzed for lithium poisoning and those for whom dialysis was recommended by PCC but not done: what lesson can we learn?

AIMS: To compare patients for whom hemodialysis was done for lithium poisoning and those for whom it was recommended by the poison control centre (PCC) but not done and to evaluate the effect of withholding hemodialysis on outcomes. METHODS: All lithium overdoses brought to the attention of the PCC were prospectively followed from January 1 to December 31, 1996. Patients for whom hemodialysis was done were compared with those for whom it was recommended but not done in terms of clinical presentation, lithium elimination half-life, need for transfer to another centre for hemodialysis, and outcome (death, or sequel or recovery). RESULTS: A total of 205 cases of lithium overdoses were collected including 110 with levels higher than 1.5 mmol/l. There were 12 acute lithium overdoses; no patients required hemodialysis and there were no sequel or deaths. There were 174 acute on chronic overdoses; hemodialysis was recommended in 9 patients but only 6 underwent hemodialysis; one patient died during hemodialysis but no other had sequel. There were 19 chronic poisonings; hemodialysis was recommended in 9 patients but only 2 had hemodialysis, a third patient underwent hemodialysis despite it not being recommended; one patient died without hemodialysis and one other had sequel after hemodialysis. No difference were observed between the groups for age, sex, type of poisoning (acute on chronic/chronic), levels (initial/peak/6 hours/extrapolated at 30 hours), time of presentation post-ingestion, presence of co-ingestants, symptoms and signs, Hansen and Amdisen grade, initial creatinine, time of recommendation to perform hemodialysis (daytime or nighttime), need to transfer patients to another centre to perform hemodialysis, and outcome. Patients with acute on chronic poisoning that were not hemodialyzed had longer elimination half-life than those for whom hemodialysis was done even before hemodialysis was performed: 50.1 +/- 13.6 h (n = 3) versus 12.9 +/-12.1 (n = 3) (p = 0.007), respectively. CONCLUSION: No difference was observed between patients for whom hemodialysis was done and those for whom it was recommended by PCC but not done. Despite the death of one patient clearly associated with voluntary withholding hemodialysis, sequel was not seen in that group. The indications for hemodialysis in lithium poisoning should be reconsidered to include only the more severe cases.

Recommendations for using fluoride to prevent and control dental caries in the United States. Centers for Disease Control and Prevention.

Widespread use of fluoride has been a major factor in the decline in the prevalence and severity of dental caries (i.e., tooth decay) in the United States and other economically developed countries. When used appropriately, fluoride is both safe and effective in preventing and controlling dental caries. All U.S. residents are likely exposed to some degree to fluoride, which is available from multiple sources. Both health-care professionals and the public have sought guidance on selecting the best way to provide and receive fluoride. During the late 1990s, CDC convened a work group to develop recommendations for using fluoride to prevent and control dental caries in the United States. This report includes these recommendations, as well as a) critical analysis of the scientific evidence regarding the efficacy and effectiveness of fluoride modalities in preventing and controlling dental caries, b) ordinal grading of the quality of the evidence, and c) assessment of the strength of each recommendation. Because frequent exposure to small amounts of fluoride each day will best reduce the risk for dental caries in all age groups, the work group recommends that all persons drink water with an optimal fluoride concentration and brush their teeth twice daily with fluoride toothpaste. For persons at high risk for dental caries, additional fluoride measures might be needed. Measured use of fluoride modalities is particularly appropriate during the time of anterior tooth enamel development (i.e., age <6 years). The recommendations in this report guide dental and other health-care providers, public health officials, policy makers, and the public in the use of fluoride to achieve maximum protection against dental caries while using resources efficiently and reducing the likelihood of enamel fluorosis. The recommendations address public health and professional practice, self-care, consumer product industries and health agencies, and further research. Adoption of these recommendations could further reduce dental caries in the United States and save public and private resources.

Access to elective vascular surgery within the recommended time according to emergency referrals.

BACKGROUND: Referral pattern is a potential confounding factor when waiting-list performance is reported across hospitals or periods. A common concern is the ability to accurately estimate proportions of patients undergoing surgery in the recommended time without considering emergency caseload. In this study, the relation between emergency referrals and the rate of elective admissions to hospital within the recommended time was estimated. DESIGN: A prospective cohort study. SETTING: An acute care hospital in Kingston, Ont. PATIENTS: Between 1994 and 1999, 1,173 consecutive patients accepted for elective vascular surgery. MAIN OUTCOME MEASURES: The proportion of patients who underwent surgery within the recommended time, and time to surgery. STUDY VARIABLES: The weekly number of emergency cases, enrolment periods, urgency and type of surgery. RESULTS: Overall, the proportion of patients who underwent surgery within recommended time was 0.45, (95% confidence interval [CI], 0.42-0.48). Adjusted for enrolment period, urgency and type of surgery, the estimated proportion was 0.57, (95% CI, 0.49-0.64). Compared with surgery for peripheral vascular disease, the odds of the procedure being done within the recommended time were 34% lower for aortic abdominal aneurysm repair and 41% lower for carotid endarterectomy. After adjustment for the case-mix and access attributes, the rate of elective admission within recommended time was on average 30% lower for weeks in which there were 1 to 2 emergency cases (rate ratio [RR] = 0.70, [95% CI, 0.53- 0.93]), and 39% lower for weeks with 3 or more emergency cases (RR = 0.61 [95% CI, 0.53-0.83]), relative to weeks with no emergency cases. CONCLUSIONS: When there is an increase in the number of emergency cases, a lower proportion of patients undergo elective surgery within the recommended time. Thus, when performance of surgical servces is evaluated, the probability of patients undergoing elective surgery on time should be adjusted relative to the number of emergency referrals.

Revised recommendations for HIV screening of pregnant women.

These guidelines replace CDC's 1995 guidelines, U.S. Public Health Service Recommendations for Human Immunodeficiency Virus Counseling and Voluntary Testing for Pregnant Women, and are for public- and private-sector service providers who provide health care for pregnant women. In 1998, the Institute of Medicine (IOM) published a report that recommended simple, routine, and voluntary human immunodeficiency virus (HIV) testing for all pregnant women in antenatal settings, given the effective interventions available to treat HIV-infected women and reduce risk for perinatal HIV transmission. In 1999, CDC convened consultation groups to discuss and comment on the IOM report. These guidelines are based on input from these meetings, the IOM report, and public comment on draft guidelines published in Fall 2000 in the Federal Register. These guidelines were also prompted by scientific and programmatic advances in the prevention of perinatally acquired HIV and care of HIV-infected women. These recommendations are consistent with the Revised Guidelines for HIV Counseling, Testing, and Referral. Major revisions from the 1995 guidelines include: emphasizing HIV testing as a routine part of prenatal care and strengthening the recommendation that all pregnant women be tested for HIV; recommending simplification of the testing process so that pretest counseling is not a barrier to testing; making the consent process more flexible to allow for various types of informed consent; recommending that providers explore and address reasons for refusal of testing; and emphasizing HIV testing and treatment at the time of labor and delivery for women who have not received prenatal testing and antiretroviral drugs. These guidelines recommend voluntary HIV testing to preserve a woman's right to participate in decisions regarding testing to ensure a provider-patient relationship conducive to optimal care for mothers and infants and to support a woman's right to refuse testing if she does not think it is in her best interest.

[Nutrition and health--recommendations of the Health Council of the Netherlands regarding energy, proteins, fats and carbohydrates].

The present report of the Health Council of the Netherlands, entitled 'Dietary reference intakes: energy, proteins, fats and digestible carbohydrates' is the second of a series of updated and revised recommendations in which the emphasis has shifted from nutritional deficiencies to the risks for some chronic diseases caused by the affluent nutrition of the 'developed' Western countries. The recommendation for total fat differs between people with an optimum weight and those who are overweight. The range for normal intake, from 20 to 40 energy per cent, has been enlarged due to a higher upper threshold. For persons who are already overweight, the narrower range from 20 to 30/35 energy percent has been maintained. Due attention should be given to the fatty acid composition of the fat and the favourable effects of unsaturated fatty acids on some chronic diseases, particularly coronary heart disease. The adequate intake of alpha-linolenic acid has been raised to 1 energy per cent while maintaining linoleic acid at 2 energy per cent. The benefits of the n-3-polyunsaturated fatty acids from fish are emphasised. Trans fatty acids should be limited to 1 energy per cent. The recommendation of 50 to 40 energy per cent for digestible carbohydrates from birth to old age is lower than in foreign recommendations. The estimate is derived from the production of endogenous glucose. No specific effects on chronic diseases are known. The recommended dietary allowances for protein are lower than those in the previous Dutch recommendation. They are now in line with most recommendations in other countries. With respect to the energy requirement, an abnormal level of physical activity should be reflected in a correction factor on the normal energy consumption.

[Laboratory variables and stratification of small-cell lung cancer patients: recommendations for therapeutic trials and for clinical practice guidelines].

OBJECTIVE: To identify, through a systematic review of the literature, the laboratory variables that, in addition to performance status and to extent of the disease, would allow a more accurate stratification of small-cell lung cancer patients who participate in chemotherapy trials, with or without radiotherapy. Secondary aim: to compare the results of our systematic review with the recommendations made in current clinical practice guidelines. METHODS: Update of two recently published systematic reviews, without meta-analysis, following the recommendations of the International Federation of Clinical Chemistry and Laboratory Medicine, and taking into account the Consolidated Standards of Reporting Trials statement. RESULTS: Of 1143 publications retrieved, exclusion and inclusion criteria allow us to include 13 studies in our review. The three variables which were the most often found significant in multivariate statistical analysis, were: pre-therapeutic levels of laboratory variables (13/13), performance status (12/13), and degree of tumour invasion (10/10). Among the laboratory variables, serum lactate dehydrogenase (LDH) is the only one that was quite consistently found to be of independent prognostic significance, with p values or hazard ratios quite close to those obtained with performance status, or with extent of the disease. The recommendations made in the four clinical practice guidelines that we retrieved, are often vague regarding laboratory variables, and sometimes they even contradict each others. CONCLUSIONS: Available evidence would support the recommendation that pretreatment LDH should be systematically measured in order to stratify patients in therapeutic trials. If other laboratory variables were to be measured in addition to LDH for this purpose, it seems that alkaline phosphatase (ALP), and to a lesser extent, sodium and white blood cell counts, might be the best suited ones. Nevertheless, further studies are necessary to more clearly support this latter recommendation. Available evidence would not support the measurement of any other laboratory variable in this context, before, during, or after treatment. Our recommendations are more in agreement with the recommendations made in the clinical practice guidelines that use evidence-based methods than with the guidelines that do not.

Physician agreement with US Preventive Services Task Force recommendations.

BACKGROUND: No large-scale work has yet assessed the reactions of physicians to the report of the US Preventive Services Task Force (USPSTF), despite its potential for fostering a consensus among practitioners. This study undertook a survey of family physicians to assess their agreement with the recommendations of the Task Force. METHODS: A survey containing the verbatim summary recommendations of the USPSTF was mailed to all 1784 active members of the Ohio Academy of Family Physicians. RESULTS: No evidence of selection bias was found among the 898 responding physicians. The average physician agreed with 88% of the recommendations. For a number of recommendations, however, particularly those in which the Task Force differed with the American Cancer Society, there was a high level of disagreement. Physician disagreement with the recommendations was associated with older age, not having completed a residency, male sex, less prior exposure to the USPSTF guidelines, and greater perception of the impracticality of applying them. CONCLUSIONS: The high level of agreement with most USPSTF recommendations implies that they represent an emerging consensus about which preventive services should be delivered. Attempts at USPSTF guideline dissemination should focus on recommendations with high agreement. Additional research is needed to assess the reasons for disagreement.
