Do clinicians want recommendations? A multicenter study comparing evidence summaries with and without GRADE recommendations.

OBJECTIVES: Evidence-based clinical practice guidelines provide recommendations to assist clinicians in decision-making and to reduce the gap between best current research evidence and clinical practice. However, some argue that providing preappraised evidence summaries alone, rather than recommendations, is more appropriate. The objective of the study is to evaluate clinicians' preferences, and understanding of the evidence and intended course of action in response to evidence summaries with and without recommendations. STUDY DESIGN SETTING: We included practicing clinicians attending educational sessions across 10 countries. Clinicians were randomized to receive relevant clinical scenarios supported by research evidence of low or very low certainty and accompanied by either strong or weak recommendations developed with the GRADE system. Within each group, participants were further randomized to receive the recommendation plus the corresponding evidence summary or the evidence summary alone. We evaluated participants' preferences and understanding for the presentation strategy, as well as their intended course of action. RESULTS: One hundred eighty-nine of 219 (86%) and 201 of 248 (81%) participants preferred having recommendations accompanying evidence summaries for both strong and weak recommendations, respectively. Across all scenarios, less than half of participants correctly interpreted information provided in the evidences summaries (e.g., estimates of effect, certainty in the research evidence). The presence of a recommendation resulted in a more appropriate intended course of action for two scenarios involving strong recommendations. CONCLUSION: Evidence summaries alone are not enough to impact clinicians' course of action. Clinicians clearly prefer having recommendations accompanying evidence summaries in the context of low or very low certainty of evidence (Trial registration NCT02006017).

Resistance and clonality in Escherichia coli and Klebsiella spp. and relationship with antibiotic consumption in major Lebanese hospitals.

OBJECTIVES: Extended-spectrum ß-lactamases (ESBLs) are increasingly detected globally among Escherichia coli and Klebsiella spp. Studies show a link between inappropriate use of antibiotics and resistance. In this study, the profiles of ESBLs in E. coli and Klebsiella spp. isolated from three Lebanese hospitals and their relationship to antibiotic consumption were determined. METHODS: A total of 300 E. coli and 91 Klebsiella spp. isolates resistant to third- or fourth-generation cephalosporins were collected between May 2011 and December 2012. Antibiotic susceptibility and consumption data were also collected from 2010-2012. Double-disk synergy and Etest ESBL assays were performed, followed by PCR for ESBL genes. Pulsed-field gel electrophoresis (PFGE) was performed for representative isolates. Statistical analysis for consumption and susceptibility data over 3 years was performed. RESULTS: Similar to other Lebanese studies, CTX-M-15 was predominant. Among the Klebsiella spp. isolated in hospitals 1 and 2, 43% harboured four different ESBLs. Eight Klebsiella spp. and fourteen E. coli pulsotypes were detected, showing genetic diversity among isolates. A significant correlation was detected between total use of antimicrobial agents and resistance to various antibiotics. A correlation was also detected between use of penicillins and resistance to aztreonam, ceftazidime and ciprofloxacin, and use of third- and fourth-generation cephalosporins and resistance to ceftazidime, cefuroxime, cefoxitin and ciprofloxacin in Klebsiella spp. (P<0.05). CONCLUSIONS: This study shows the predominance of CTX-M-15 among cephalosporin-resistant E. coli and Klebsiella spp. in Lebanese hospitals. It also shows that the heightened use of antibiotics could be a driving factor for resistance emergence.

Risk Factors, Clinical Presentation, and Outcome of Acinetobacter baumannii Bacteremia.

Infections caused by Acinetobacter baumannii (AB), an increasingly prevalent nosocomial pathogen, have been associated with high morbidity and mortality. We conducted this study to analyze the clinical features, outcomes, and factors influencing the survival of patients with AB bacteremia. We retrospectively examined the medical records of all patients developing AB bacteremia during their hospital stay at a tertiary care hospital in Beirut between 2010 and 2015. Ninety episodes of AB bacteremia were documented in eighty-five patients. Univariate analysis showed that prior exposure to high dose steroids, diabetes mellitus, mechanical ventilation, prior use of colistin and tigecycline, presence of septic shock, and critical care unit stay were associated with a poor outcome. High dose steroids and presence of septic shock were significant on multivariate analysis. Crude mortality rate was 63.5%. 70.3% of the deaths were attributed to the bacteremia. On acquisition, 39 patients had septicemia. Despite high index of suspicion and initiation of colistin and/or tigecycline in 18/39 patients, a grim outcome could not be averted and 37 patients died within 2.16 days. Seven patients had transient benign bacteremia; three of which were treated with removal of the line. The remaining four did not receive any antibiotics due to withdrawal of care and died within 26.25 days of acquiring the bacteremia, with no signs of persistent infection on follow up. A prolonged hospital stay is frequently associated with loss of functionality, and steroid and antibiotic exposure. These factors seem to impact the mortality of AB bacteremia, a disease with high mortality rate and limited therapeutic options.

Etiology, seasonality, and clinical characterization of viral respiratory infections among hospitalized children in Beirut, Lebanon.

Acute respiratory tract viral infections occur worldwide and are one of the major global burdens of diseases in children. The aim of this study was to determine the viral etiology of respiratory infections in hospitalized children, to understand the viral seasonality in a major Lebanese hospital, and to correlate disease severity and the presence of virus. Over a 1-year period, nasal and throat swabs were collected from 236 pediatric patients, aged 16-year old or less and hospitalized for acute respiratory illness. Samples collected were tested for the presence of 17 respiratory viruses using multiplex real-time RT-PCR. Pathogens were identified in 165 children (70%) and were frequently observed during fall and winter seasons. Co-infection was found in 37% of positive samples. The most frequently detected pathogens were human Rhinovirus (hRV, 23%), Respiratory Syncytial Virus (RSV, 19%), human Bocavirus (hBov, 15%), human Metapneumovirus (hMPV, 10%), and human Adenovirus (hAdV, 10%). A total of 48% of children were diagnosed with bronchiolitis and 25% with pneumonia. While bronchiolitis was often caused by RSV single virus infection and hAdV/hBoV coinfection, pneumonia was significantly associated with hBoV and HP1V1 infections. No significant correlation was observed between a single viral etiology infection and a specific clinical symptom. This study provides relevant facts on the circulatory pattern of respiratory viruses in Lebanon and the importance of using PCR as a useful tool for virus detection. Early diagnosis at the initial time of hospitalization may reduce the spread of the viruses in pediatric units. J. Med. Virol. 88:1874-1881, 2016. © 2016 Wiley Periodicals, Inc.

Arthroscopic treatment of non-homogeneous calcifying tendinitis of the rotator cuff.

The purpose of this study is to investigate the clinical outcome of arthroscopic treatment for patients with non-homogeneous infiltrated calcifying tendinitis of the rotator cuff (type III), and to assess the optimal method for this arthroscopic treatment. We retrospectively reviewed the charts of 81 patients who underwent arthroscopic treatment for non-homogeneous infiltrated calcifying tendinitis of the rotator cuff (type III). Patients were divided into two groups: Group A (n = 31) consisted of patients who underwent excision of calcification, and Group B comprised patients who underwent acromioplasty alone (n = 50). The clinical outcome of treatment was assessed using Constant-Murley score. Twenty-three of the 81 patients were males and 58 were females. The mean duration of symptoms from onset to the first clinic visit was 3.88 years (SD ± 3.06 years). The right side was involved in 47 patients, the left side in 34 patients, and none had bilateral involvement. Patients from Group B had higher 16 improvement of their Constant-Murley score (from 48.96 to 88.06) when 17 compared to group A (from 45.39 to 67.23). Treatment of type III calcifying tendinitis is different than type I and II. Subacromial decompression may be considered in all patients suffering from type III non-homogeneous infiltrated calcifying tendinitis of the shoulder.

EFFECTS OF PREOPERATIVE ENOXAPARIN ON BLEEDING AFTER CORONARY ARTERY BYPASS SURGERY.

BACKGROUND: Low molecular weight heparins are replacing unfractionated heparin in practice prior to cardiac surgery. This study examines postoperative (post-op) bleeding indicators in patients who received enoxaparin and underwent elective isolated first time coronary artery bypass graft. METHODS: A total of 125 consecutive patients who underwent this procedure between 2009 and 2011 at one tertiary center were reviewed and divided into three groups: Group A (n = 50) received the last dose of enoxaparin between 12 and 24 hours before surgery, Group B (n = 25) received the last dose before 24 hours and Group C (n = 50) did not receive enoxaparin. Perioperative bleeding indicators and transfusion rates were compared. RESULTS: Preoperative patients' characteristics were comparable between the three groups. There were no perioperative deaths, return to the operating room for any reason, nor major bleeding. Post-op bleeding indicators were similar in the three groups. The average chest tube drainage at 24 hours post-op was 880 mL, 695 mL and 830 mL in Group A, B and C respectively (p = 0.71). Transfusion rates of red blood cells were not statistically different (Group A 56%, B 64% & C 62%; p = 0.747). In multivariate analysis, female gender, older age, and preoperative clopidogrel intake (stopped 5 days prior to surgery) were associated with higher transfusion rates. CONCLUSION: In elective first time coronary artery bypass graft patients who had no aspirin or clopidogrel intake 5 days prior to surgery, the use of enoxaparin up to 12 hours prior to skin incision does not increase the risk of post-op bleeding.

Nursing faculty teaching a module in clinical skills to medical students: a Lebanese experience.

Nursing faculty teaching medical students a module in clinical skills is a relatively new trend. Collaboration in education among medical and nursing professions can improve students' performance in clinical skills and consequently positively impact the quality of care delivery. In 2011, the Faculty of Medicine in collaboration with the Faculty of Health Sciences at the University of Balamand, Beirut, Lebanon, launched a module in clinical skills as part of clinical skills teaching to first-year medical students. The module is prepared and delivered by nursing faculty in a laboratory setting. It consists of informative lectures as well as hands-on clinical practice. The clinical competencies taught are hand-washing, medication administration, intravenous initiation and removal, and nasogastric tube insertion and removal. Around sixty-five medical students attend this module every year. A Likert scale-based questionnaire is used to evaluate their experience. Medical students agree that the module provides adequate opportunities to enhance clinical skills and knowledge and favor cross-professional education between nursing and medical disciplines. Most of the respondents report that this experience prepares them better for clinical rotations while increasing their confidence and decreasing anxiety level. Medical students highly appreciate the nursing faculties' expertise and perceive them as knowledgeable and resourceful. Nursing faculty participating in medical students' skills teaching is well perceived, has a positive impact, and shows nurses are proficient teachers to medical students. Cross professional education is an attractive model when it comes to teaching clinical skills in medical school.

Motives, beliefs and attitudes towards waterpipe tobacco smoking: a systematic review.

BACKGROUND: In spite of the negative health effects of waterpipe tobacco smoking, its use is becoming more common. The objective of this study is to systematically review the medical literature for motives, beliefs and attitudes towards waterpipe tobacco smoking. METHODS: We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science in January 2012. We included both quantitative and qualitative studies. We selected studies and abstracted data using standard systematic review methodology. We synthesized data qualitatively. RESULTS: We included 58 papers reporting on 56 studies. The main motives for waterpipe tobacco smoking were socializing, relaxation, pleasure and entertainment. Peer pressure, fashion, and curiosity were additional motives for university and school students while expression of cultural identity was an additional motive for people in the Middle East and for people of Middle Eastern descent in Western countries. Awareness of the potential health hazards of waterpipe smoking was common across settings. Most but not all studies found that the majority of people perceived waterpipe smoking as less harmful than cigarette smoking. Waterpipe smoking was generally socially acceptable and more acceptable than cigarette smoking in general. In Middle Eastern societies, it was particularly more acceptable for women's use compared to cigarette use. A majority perceived waterpipe smoking as less addictive than cigarette smoking. While users were confident in their ability to quit waterpipe smoking at any time, willingness to quit varied across settings. CONCLUSIONS: Socializing, relaxation, pleasure and entertainment were the main motives for waterpipe use. While waterpipe users were aware of the health hazards of waterpipe smoking, they perceived it as less harmful, less addictive and more socially acceptable than cigarette smoking and were confident about their ability to quit.

Influenza A (H1N1) 2009 pandemia. The experience of a tertiary care center in Beirut.

INTRODUCTION: In March 2009, a new influenza virus strain emerged, currently known as the 2009 pandemic H1N1 virus. The virus first appeared in Mexico and rapidly spread globally to reach a pandemic level in June of the same year. We describe here the experience of one major referral center in Beirut, Lebanon. MATERIALS AND METHODS: The laboratory department at St. George Hospital University Medical Center received respiratory specimens from hospital wards, the emergency department, in addition to a considerable proportion collected directly from "outpatients" in the lab. We used the real time RT-PCR as our main diagnostic test. We collected data about the patients from the laboratory information system and from the hospital medical records department. RESULTS: From mid-August 2009 till the end of January 2010, a total of 1771 specimens were analyzed, with 948 (53.5%) returning positive for influenza A (H1N1) by RT-PCR. Only 79 patients with H1N1 infection required hospitalization. Most of H1N1 confirmed patients were children and adolescents aged 5 to 17 years and young adults between 25 and 44 years. The most common symptoms at presentation were: fever, cough, shortness of breath, chills, rhinorrhea or nasal congestion, as well as gastrointestinal symptoms. Twenty-three patients required ICU care and eight patients died. The vast majority had an uncomplicated course of illness and was managed in an outpatient setting. CONCLUSION: The percentage of positive tests during the pandemia was significantly elevated, although few patients experienced drastic clinical outcomes.

Willingness of Lebanese physicians in the United States to relocate to Lebanon.

BACKGROUND: We recently proposed that Lebanon could become a regional 'academic hub' through the repatriation of emigrated Lebanese physicians who would then provide clinical services in the Arab Gulf region on a locum tenens basis. The objectives of this study were to assess the willingness of Lebanese medical graduates practicing in the United States of America to relocate to Lebanon and the Arab Gulf region and to explore the factors associated with this willingness. METHODS: In 2009 we surveyed Lebanese medical graduates practicing medicine in the United States. The questionnaire included questions about their willingness to relocate to Lebanon and to the Arab Gulf region and the associated timeframes. The questionnaire also included questions about family factors. We linked responders' answers to their personal, educational, and practice characteristics provided by the American Medical Association Physicians' Dataset. We conducted both descriptive and regression analyses. RESULTS: A total of 286 physicians participated in the survey (57% response rate). A majority (61%) was willing to relocate to Lebanon (51% possibly, 10% definitely). A third (33%) were willing to relocate to the Arab Gulf region (31% possibly, 2% definitely). About half (54%) were willing to relocate to Lebanon as a base for clinical missions to the Arab Gulf region (49% possibly, 5% definitely). Willingness to relocate to Lebanon was independently associated with Lebanese citizenship and the birthplace of the spouse being Lebanon, and inversely associated with US citizenship. Willingness to relocate to the Arab Gulf region was independently associated with being board certified, and inversely associated with being married, the age of the oldest child, and practicing in direct patient care. Willingness to relocate to Lebanon as a base was not independently associated with any factor. CONCLUSIONS: The findings of this study support the feasibility of the proposal of Lebanon becoming a regional 'academic hub'. Future research should explore other factors important for the feasibility of the proposal as well as actual relocation.

Acquired and genetic risk factors for deep vein thrombosis of lower extremities among Lebanese patients.

AIM: Venous thrombosis results from the interaction of environmental and genetic risk factors. These factors vary according to the ethnic and geographic distribution of the populations. The aim of this study is to define the role of acquired and genetic risk factors for venous thrombosis of lower extremities among Lebanese patients assessed in a university hospital and to discuss them according to the international literature. MATERIAL AND METHODS: From January 2005 to January 2010, 166 patients (72 males and 94 females) were diagnosed with lower extremity deep vein thrombosis. Mean age was 67 years (range: 25 to 96 years). RESULTS: The most frequently reported acquired risk factors for venous thrombosis in this study were advanced age, obesity, history of venous thromboembolism, immobilization, surgery, varicose veins and malignancy. Screening for prothrombotic genetic abnormalities was requested in patients with conditions highly suggestive of hypercoagulation state such as young patients, patients with spontaneous, recurrent or extensive venous thrombosis, patients with family history, oral contraceptives, air travel and pregnancy. All the 45 patients (27.1%) tested for thrombophilia were positive and were carriers for factors V-Leiden (17.4%), MTHFR C 677 T (16.8%), MTHFR A 1298 C (4.8%), II G 20210 A (1.8%) and V H 1299 R (1.2%) mutation. Twelve patients (7.2%) had increased homocysteine level. CONCLUSION: Advanced age is the most common risk factor for venous thrombosis in these series. Thrombophilia is the second most frequently observed risk factor and is related to the high prevalence of factor V-Leiden and MTHFR C 677 T mutation among the Lebanese population.

"Might" or "suggest"? No wording approach was clearly superior in conveying the strength of recommendation.

OBJECTIVE: To compare different wording approaches for conveying the strength of health care recommendations. STUDY DESIGN AND SETTING: Participants were medical residents in Canada and the United States. We randomized them to one of three wording approaches, each expressing two strengths of recommendation, strong and weak: (1) "we recommend," "we suggest;" (2) "clinicians should," "clinicians might;" (3) "we recommend," "we conditionally recommend." Each participant received one strong and one weak recommendation. For each recommendation, they chose a hypothetical course of action; we judged whether their choice was appropriate for the strength of the recommendation. RESULTS: The response rate was 77% (341/441). Most participants, in response to strong recommendations, chose hypothetical courses of action appropriate for weak recommendations. None of the wording approaches was clearly superior in conveying the strength of a recommendation. However, different approaches appeared superior depending on the strength and direction (for or against an intervention) of the recommendation. CONCLUSION: No wording approach was clearly superior in conveying the strength of recommendation. Guideline developers need to make the connection between the wording and their intended strength explicit.

The prevalence of waterpipe tobacco smoking among the general and specific populations: a systematic review.

BACKGROUND: The objective of this study was to systematically review the medical literature for the prevalence of waterpipe tobacco use among the general and specific populations. METHODS: We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included cohort studies and cross sectional studies assessing the prevalence of use of waterpipe in either the general population or a specific population of interest. Two reviewers used a standardized and pilot tested form to collect data from each eligible study using a duplicate and independent screening process. We stratified the data analysis by country and by age group. The study was not restricted to a specific context. RESULTS: Of a total of 38 studies, only 4 were national surveys; the rest assessed specific populations. The highest prevalence of current waterpipe smoking was among school students across countries: the United States, especially among Arab Americans (12%-15%) the Arabic Gulf region (9%-16%), Estonia (21%), and Lebanon (25%). Similarly, the prevalence of current waterpipe smoking among university students was high in the Arabic Gulf region (6%), the United Kingdom (8%), the United States (10%), Syria (15%), Lebanon (28%), and Pakistan (33%). The prevalence of current waterpipe smoking among adults was the following: Pakistan (6%), Arabic Gulf region (4%-12%), Australia (11% in Arab speaking adults), Syria (9%-12%), and Lebanon (15%). Group waterpipe smoking was high in Lebanon (5%), and Egypt (11%-15%). In Lebanon, 5%-6% pregnant women reported smoking waterpipe during pregnancy. The studies were all cross-sectional and varied by how they reported waterpipe smoking. CONCLUSION: While very few national surveys have been conducted, the prevalence of waterpipe smoking appears to be alarmingly high among school students and university students in Middle Eastern countries and among groups of Middle Eastern descent in Western countries.

Effects of water-pipe smoking on lung function: a systematic review and meta-analysis.

BACKGROUND: Although common in many Middle Eastern countries, water-pipe tobacco smoking, commonly known as water-pipe smoking (WPS), is increasingly popular in Western cultures. The primary objective of this study was to systematically review the effects of WPS on lung function. The secondary objective was to compare the effects of WPS and cigarette smoking on lung function. METHODS: We conducted a systematic review using the approach of the Cochrane Collaboration to search for, select, and abstract studies. We conducted two separate meta-analyses comparing water-pipe smokers with nonsmokers, and water-pipe smokers with cigarette smokers for each of three spirometric measurements (FEV1, FVC, and FEV1/ FVC). We used the standardized mean difference (SMD) to pool the results. RESULTS: Six cross-sectional studies were eligible for this review. Compared with no smoking, WPS was associated with a statistically significant reduction in FEV1 (SMD = -0.43; 95% CI, -0.58 to -0.29; equivalent to a 4.04% lower FEV1%), a trend toward lower FVC (SMD = -0.15; 95% CI, -0.34 to 0.04; equivalent to a 1.38% reduction in FVC%), and lower FEV1/ FVC (SMD = -0.46; 95% CI, -0.93 to 0.01; equivalent to a 3.08% lower FEV1/ FVC). Comparing WPS with cigarette smoking, there was no statistically significant difference in FEV1, FVC, and FEV1/ FVC. The six studies suffered from methodologic limitations. CONCLUSIONS: WPS negatively affects lung function and may be as harmful as cigarette smoking. WPS, therefore, is likely to be a cause of COPD.

Survey instruments used in clinical and epidemiological research on waterpipe tobacco smoking: a systematic review.

BACKGROUND: The primary objective was to systematically review the medical literature for instruments validated for use in epidemiological and clinical research on waterpipe smoking. METHODS: We searched the following databases: MEDLINE, EMBASE, and ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included papers reporting on the development and/or validation of survey instruments to measure waterpipe tobacco consumption or related concepts. Two reviewers used a standardized and pilot tested data abstraction form to collect data from each eligible study using a duplicate and independent screening process. We also determined the percentage of observational studies assessing the health effects of waterpipe tobacco smoking and the percentage of studies of prevalence of waterpipe tobacco smoking that have used validated survey instruments. RESULTS: We identified a total of five survey instruments. One instrument was designed to measure knowledge, attitudes, and waterpipe use among pregnant women and was shown to have internal consistency and content validity. Three instruments were designed to measure waterpipe tobacco consumption, two of which were reported to have face validity. The fifth instrument was designed to measure waterpipe dependence and was rigorously developed and validated. One of the studies of prevalence and none of the studies of health effects of waterpipe smoking used validated instruments. CONCLUSIONS: A number of instruments for measuring the use of and dependence on waterpipe smoking exist. Future research should study content validity and cross cultural adaptation of these instruments.

The effects of waterpipe tobacco smoking on health outcomes: a systematic review.

BACKGROUND: There is a need for a comprehensive and critical review of the literature to inform scientific debates about the public health effects of waterpipe smoking. The objective of this study was therefore to systematically review the medical literature for the effects of waterpipe tobacco smoking on health outcomes. METHODS: We conducted a systematic review using the Cochrane Collaboration methodology for conducting systematic reviews. We rated the quality of evidence for each outcome using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS: Twenty-four studies were eligible for this review. Based on the available evidence, waterpipe tobacco smoking was significantly associated with lung cancer [odds ratio (OR) = 2.12; 95% confidence interval (CI) 1.32-3.42], respiratory illness (OR = 2.3; 95% CI 1.1-5.1), low birth-weight (OR = 2.12; 95% CI 1.08-4.18) and periodontal disease (OR = 3-5). It was not significantly associated with bladder cancer (OR = 0.8; 95% CI 0.2-4.0), nasopharyngeal cancer (OR = 0.49; 95% CI 0.20-1.23), oesophageal cancer (OR = 1.85; 95% CI 0.95-3.58), oral dysplasia (OR = 8.33; 95% CI 0.78-9.47) or infertility (OR = 2.5; 95% CI 1.0-6.3) but the CIs did not exclude important associations. Smoking waterpipe in groups was not significantly associated with hepatitis C infection (OR = 0.98; 95% CI 0.80-1.21). The quality of evidence for the different outcomes varied from very low to low. CONCLUSION: Waterpipe tobacco smoking is possibly associated with a number of deleterious health outcomes. There is a need for high-quality studies to identify and quantify with confidence all the health effects of this form of smoking.

The use of electronic health records in the exam room and patient satisfaction: a systematic review.

BACKGROUND: Physicians may hesitate to implement electronic health record (EHR) systems because they fear a decrease in patient satisfaction. We conducted a systematic review to determine whether physician EHR use in the patient room affects patient satisfaction. METHODS: We searched the literature using MEDLINE (Ovid), EMBASE, CINAHL, Cochrane Library, PsycINFO, Proceedings First, and ProQuest Digital Dissertations. Our inclusion criteria were a description of physician EHR use in the examination room, EHR use in an outpatient setting, setting in the United States, publication year no earlier than 2000, and measurement of patient satisfaction. We included both qualitative and quantitative research. We included 7 articles in the final analysis: 3 cross-sectional, and 4 pre-design and post-design. RESULTS: Several studies had methodological concerns. Six studies found that physician EHR use had either a positive or neutral effect on patient satisfaction. One study found a negative effect on the physicians' perception of patient satisfaction. The reported statistical results from these studies were not homogenous enough for meta-analysis. CONCLUSION: Studies examining physician EHR use have found mostly neutral or positive effects on patient satisfaction, but primary care researchers need to conduct further research for a more definitive answer.

Awareness of body weight status among family medicine clinic patients.

OBJECTIVES: a) determine the prevalence of accurate perceptions of body weight status; b) assess awareness of risk and willingness to change; c) assess physicians' documentation of a weight problem. DESIGN: cross-sectional survey of 356 clinic patients. MEASURES: patient questionnaire; data extracted from charts. RESULTS: BMI averaged 34 for females, 31 for males. Twenty-five percent were overweight, 35% obese and 22% morbidly obese. Fifty-seven percent underestimated their weight status. Most obese and morbidly obese patients recognized the increased risk and wanted to change. Only the overweight patients who were accurate considered themselves at risk and wanted to change. Only 17% of office charts included the weight problem in the cumulative problem list. CONCLUSION: Despite the high prevalence of inaccurate perception of weight status, most patients were aware of risk and willing to change, except for the overweight patients. This subgroup would be a good target for an intervention to increase awareness.
