Memory impairment following right hemisphere stroke: a comparative meta-analytic and narrative review.

We examined the evidence for widely held clinical beliefs about memory impairment following right hemisphere stroke (RHS), conducting both narrative and meta-analytic reviews of the literature [MEDLINE (1966-January 2003), PsycINFO (1974-January 2003), and CINAHL (1982-December 2002)]. We sought to determine whether RHS patients experience more problems with non-verbal memory than non-stroke controls (NSCs) and left hemisphere stroke (LHS) patients. Secondarily, we sought to determine whether RHS patients experience more problems with verbal memory than NSCs and fewer verbal memory problems than LHS patients. We also examined the effect of type of memory assessment (recall versus recognition) on reported findings. As regards non-verbal memory, narrative and meta-analytic reviews found that RHS patients had deficits relative to NSCs, on tests of both recall and recognition. The evidence for RHS non-verbal memory deficits relative to LHS was mixed in the narrative review, whereas the meta-analysis found RHS deficits on non-verbal recognition tests, but no difference between RHS and LHS patients on non-verbal recall tests. Deficits on recognition tests imply problems with early encoding of material or possibly its storage. Regarding verbal memory, the narrative review found that RHS patients performed more poorly than NSCs in about half of all studies. The meta-analytic review confirmed poorer RHS performance on tests of verbal recall, but none of the studies that compared RHS and NSCs on verbal recognition could be included in this type of review. The narrative review found mixed evidence as regards the performance of RHS and LHS patients on verbal memory tests, but the meta-analysis pointed to RHS superiority for both verbal recall and recognition. The relative strengths of both types of review are discussed.

Dietary supplements for body-weight reduction: a systematic review.

BACKGROUND: Compliance with conventional weight-management programs is notoriously poor, and a plethora of over-the-counter slimming aids are sold with claims of effectiveness. OBJECTIVE: The objective of the study was to assess the evidence from rigorous clinical trials, systematic reviews, and meta-analyses on the effectiveness of dietary supplements in reducing body weight. DESIGN: The study was a systematic review. Literature searches were conducted on Medline, Embase, Amed, Cinahl, and the Cochrane Library until March 2003. Hand searches of medical journals, the authors' own files, and bibliographies of identified articles were conducted. There were no restrictions regarding the language of publication. The screening of studies, selection, validation, data extraction, and the assessment of methodologic quality were performed independently by the 2 reviewers. To be included, trials were required to be randomized and double-blind. Systematic reviews and meta-analyses of dietary supplements were included if they were based on the results of randomized, double-blind trials. RESULTS: Five systematic reviews and meta-analyses and 25 additional trials were included and reviewed. Data on the following dietary supplements were identified: chitosan, chromium picolinate, Ephedra sinica, Garcinia cambogia, glucomannan, guar gum, hydroxy-methylbutyrate, plantago psyllium, pyruvate, yerba maté, and yohimbe. The reviewed studies provide some encouraging data but no evidence beyond a reasonable doubt that any specific dietary supplement is effective for reducing body weight. The only exceptions are E. sinica- and ephedrine-containing supplements, which have been associated with an increased risk of adverse events. CONCLUSIONS: The evidence for most dietary supplements as aids in reducing body weight is not convincing. None of the reviewed dietary supplements can be recommended for over-the-counter use.

Prospective peer review in surgical pathology.

Quality assurance (QA) in surgical pathology has focused primarily on retrospective audits of randomly selected cases. The authors describe an effective method of prospective audit for a selected class of surgical specimens--diagnostic biopsies--and document the benefits, additional staff time required and impact on turnaround time. Additionally, these results were compared with a retrospective review. During a 6-month period, all diagnostic surgical pathology biopsies (n = 2,694, 55% of all cases) were reviewed by a second pathologist before release of the final report. Errors detected were subdivided into four categories: (1) major: errors in diagnosis that could directly affect patient care; (2) diagnostic discrepancies: errors in diagnosis that should not affect patient care; (3) minor: correct diagnosis rendered, but report correction required to add supportive information; (4) clerical: typographical and grammatical errors. Thirty-two major errors were found, involving 1.2% of cases reviewed. This manner of review caused an increase in overall turnaround time from 1.62 days to 1.79 days, and an increase in turnaround time for diagnostic biopsies from 1.44 days to 1.50 days. Time spent in performing prospective peer review averaged 4 hours per day. For comparison, results were included from a retrospective review performed on 480 of the 5,556 cases accessioned in a 6-month period before the institution of prospective quality assurance. This retrospective review revealed eight major errors (1.7%). In conclusion, the prospective peer review of diagnostic biopsies yields sufficient benefits in increased accuracy of diagnostic reports to justify the slight increase in additional work by pathologists.

Peer review of teaching in medicine.

The design, development, and implementation of procedures for peer review of teaching are described. Peer review is one component of a comprehensive system to evaluate and improve teaching in a school of medicine. Colleague observations and judgments are used to augment student/resident ratings of teaching for purposes of instructional improvement and academic promotions. School policies have standardized evaluation criteria and instrumentation while granting departments flexibility in conducting peer review. Three different departmental peer review committee structures and procedures are reviewed. With the emphasis upon improvement, faculty acceptance of peer review of teaching has been positive. Peer review reports have had a positive impact on academic promotions. The inherent strengths and limitations of peer review of teaching are discussed in relation to the literature and to the medical school environment.

Successful peer review of courses: a case study.

The authors describe their school's system of peer review for courses, established in 1988 to facilitate faculty evaluation and continual course and curriculum improvement. (The system has been temporarily suspended while the school's new curriculum becomes established.) They explain how the system was created and then report how faculty reviews of courses over the five-year operation of the system compared with students' reviews of the same courses. The faculty and students' ratings were in agreement 75% of the time. When not in agreement, the students' ratings tended to upgrade courses that were not very demanding, had easy grading, and emphasized clinical details, often at the expense of basic concepts and the big picture. The authors then document how the work of the peer review system favorably influenced the transformation of the school's curriculum. They also provide guidelines for the creation and operation of a course review process that uses faculty peers. The authors maintain that the peer review system worked because it was run by a committee of experienced and respected teachers who had been selected by their peers, the other faculty. Additional reasons for its success were that the school's faculty supported and respected the committee and its work, that course directors helped evaluate their courses, and that peer reviewers took their work seriously despite having no remuneration, and the clearly positive impact of the review system on faculty interaction, faculty-student interaction, and the reform of the curriculum.

The challenges of IRB review and human subjects protections in practice-based research.

Practice-based research raises unique challenges with respect to human subjects protections and institutional review board (IRB) review. In this paper, three challenges posed by practice-based research are analyzed: (1) IRB review for clinician investigators who are not affiliated with an institution that has an IRB; (2) multiple IRB review; and (3) required human subjects protection training of key personnel. Investigators should be proactive in addressing required IRB review in practice-based research. In particular, they need to ensure that appropriate IRB review is obtained for all performance sites and plan for review for unaffiliated investigators. Practice-based research investigators and professional societies should educate IRB members and policy makers and publish articles regarding how IRBs might best address human subjects concerns in practice-based research. Furthermore, practice-based research investigators and professional societies should work with IRBs and the Office for Human Research Protections to facilitate centralized or cooperative review of practice-based research. Finally, practice-based research investigators need to ensure that their clinician investigators receive appropriate training in human subjects protection. Practice-based research investigators and professional societies can facilitate this process by helping to define and implement the appropriate training for busy practice-based research clinicians and office staff.

The quality of reports of critical care meta-analyses in the Cochrane Database of Systematic Reviews: an independent appraisal.

OBJECTIVE: To independently appraise the methodological quality of a sample of reports of meta-analyses that address critical care topics in the Cochrane Database of Systematic Reviews compared with the quality of reports published in regular journals, using a validated assessment instrument, the Overview Quality Assessment Questionnaire (OQAQ). DATA SOURCE: Studies were selected from a search of MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from 1994 to 2003, using multiple search terms for critical care and sensitive filters to identify meta-analyses. STUDY SELECTION: Two authors independently selected meta-analyses that addressed topics pertinent to critical care medicine. DATA EXTRACTION: Two authors independently extracted the data. The proportion of reports that met each component of the OQAQ was determined, as was the overall quality score. Meta-analyses published in the Cochrane Database of Systematic Reviews were compared with those published in regular journals. DATA SYNTHESIS: There were 36 reports of meta-analyses in the Cochrane Database of Systematic Reviews and 103 reports of meta-analyses published in regular journals; 11 of these were reports of Cochrane reviews. The meta-analyses published in the Cochrane Database of Systematic Reviews were more likely to fulfill most components of the OQAQ. The median overall OQAQ scores indicated significant methodological problems in the reports regardless of the source of publication, although the reports in the Cochrane database scored higher than those in regular journals (five compared with two, p<.001). Major methodological flaws, notably failure to appropriately refer to the validity of included studies, were found in meta-analyses in both the Cochrane Database of Systematic Reviews and regular journals (44.4% and 79.3%, respectively). CONCLUSIONS: Although the quality of reports of meta-analyses published in the Cochrane Database of Systematic Reviews is superior to the quality of reports of meta-analyses published in regular journals, there is significant room for improvement. Clinicians should critically appraise all reports of meta-analyses before considering the results, regardless of the source of publication.

The effect of income inequality and macro-level social policy on infant mortality and low birthweight in developed countries--a preliminary systematic review.

OBJECTIVE: To carry out a preliminary systematic review of literature to address the question - among rich nations (or states within nations) what is the evidence that income inequality and differences in macro-level social policy affect rates of infant mortality and low birthweight (LBW)? STUDY DESIGN: A systematic literature review. SEARCH STRATEGY: Medline database (1968-August 2003) was searched for empirical studies of the relationship between macro-level economic and social policies in rich nations and rates of infant mortality (IMR) and LBW. Cross-national comparison of infant mortality and LBW that did not compare the effects of macro-level economic and social policies was excluded from the review as were studies including less developed countries. Keywords representing IMR and LBW were entered into Medline along with exposures related to international comparison and macro-level policy. Abstracts obtained from the initial search were reviewed for relevant studies. Full papers of potentially relevant studies were obtained and reviewed for inclusion. Secondary search of papers cited in included papers was undertaken. For this review, papers were not excluded on the basis of quality although methodological limitations were commented on and taken into account in interpreting the results. Summary statistics were not estimated. RESULTS: Twelve studies, fulfilling the inclusion criteria, were identified. Ten studies examined the association of IMR with income inequality, eight of which reported a statistically significant positive association with higher levels of inequality after adjustment for a range of variables. Six studies reported significant positive associations of IMR with other indicators of less re-distributive social and economic policy. Associations with LBW were reported in four studies; three showed significant positive associations with higher levels of income inequality and one showed no association with low levels of parental leave entitlement. Methodological differences, particularly the wide range of variables used to adjust for confounding, make interpretation of the findings difficult. CONCLUSIONS: The results of this review represent a preliminary attempt to summarize the literature linking macro-level economic and social policies in rich nations with IMR and LBW. The findings, taking account of the methodological limitations of the review and of the included studies, suggest a statistically significant association between IMR and higher income inequality and other indicators of less re-distributive social policy. Only three studies examined the association of income inequality with LBW and, although they suggest a significant association, further studies will be needed to confirm this finding.

Health risks and occupational exposure to volatile anaesthetics--a review with a systematic approach.

AIMS AND OBJECTIVES: To provide practicing nurse anaesthetists with evidence based knowledge as to whether they are at risk handling volatile anaesthetics by answering the question: What are the health risks threatening health care personnel occupationally exposed to volatile anaesthetics? BACKGROUND: The interpretations of results from specific scientific studies vary and preliminary research results indicate that occupational exposure to volatile anaesthetics affects the health of operating room personnel. DESIGN: Review of scientific literature with a systematic approach. METHOD: The review included a systematic search in three major databases, a screening process of abstracts/articles followed by a quality assessment of the included studies. The screening process and the quality assessment were done independently by the six reviewers and followed specific protocols. RESULTS: A systematic search of The Cochrane Library, MedLine and CINAHL resulted in a screening of 413 abstracts of which 31 articles were assessed for quality, all done independently by the reviewers. Finally, the reviewers agreed upon how to interpret the results of the assessed articles. CONCLUSIONS: The 31 articles assessed covered areas such as genotoxic effects, neurobehavioural effects, immunology, and general health effects. In the scientific literature reviewed there is no evidence of occupational exposure to volatile anaesthetics either being associated with health risks or being harmless. Studies indicating a potential health risk are all investigating circumstances ignorant of modern environmental regulations and/or with no scavenging equipment. RELEVANCE TO CLINICAL PRACTICE: Although no answer has been given, this review illuminates the methodological difficulties encountered in designing studies. The result of this review further stresses the need for scientific knowledge in this area and enhances the extensive use of scavenging equipment.

Variations in the ability of general medical practitioners to apply two methods of clinical audit: A five-year study of assessment by peer review.

INTRODUCTION: Clinical audit has a central role in the NHS clinical governance agenda and the professional appraisal of medical practitioners in the UK. However, concerns have been raised about the poor design and impact of clinical audit studies and the ability of practitioners to apply audit methods. One method of making informed judgements on audit performance is by peer review. In the west of Scotland a voluntary peer review model has been open to general practitioners since 1999, while general practice trainees are compelled to participate as part of summative assessment. The study aimed to compare the outcomes of peer review for two methods of audit undertaken by different professional and academic groups of doctors. METHODS: Participants submitted a criterion audit or significant event analysis in standard formats for review by two informed general practitioners (GPs) using appropriate instruments. Peer review outcome data and the professional status of doctors participating were generated by computer search. Differences in proportions of those gaining a satisfactory peer review for each group were calculated. RESULTS: Of 1002 criterion audit submissions, 552 (55%) were judged to be satisfactory. GP registrars were significantly more likely than GP trainers (P < 0.001) and other established GP groups (P < 0.001) to gain a satisfactory peer review. GPs in non-training practices were less likely to achieve a satisfactory review than registrars (P < 0.001) and colleagues in training practices (P < 0.001). Of 883 SEA submissions, 541 (65%) were judged as satisfactory, with all groups gaining a similar proportion of satisfactory assessments, although GP registrars may have outperformed non-training practice GPs (P = 0.05). CONCLUSION: A significant proportion of GPs may be unable to adequately apply audit methods, potentially raising serious questions about the effectiveness of clinical audit as a health care improvement policy in general medical practice.

Two physiotherapists, one librarian and a systematic literature review: collaboration in action.

AIM: This paper explores the processes of collaboration between a librarian and two academic physiotherapists working on a systematic review jointly funded by the University of the West of England (UWE), Bristol, and the Royal National Hospital for Rheumatic Diseases (RNHRD), Bath, UK. The aim of this paper is to describe and evaluate some of the processes of collaboration between the three authors in their work in progress on a funded systematic literature review on the topic of hydrotherapy and pain. METHODS: The vehicle for describing and analysing these processes is a joint (National Health Service Trust and University) funded systematic literature review currently in progress on the topic of hydrotherapy and pain. RESULTS: Systematic review methodology is becoming increasingly complex and is rapidly developing its own research base. Librarian input is a key element in a successful systematic review. CONCLUSIONS: Systematic reviews play a critical role in informing healthcare delivery and research in the UK. The individual nature and inherent complexity of each review demands close collaboration between librarians, academics and clinicians. In addition to enhancing the reviews themselves, there are many other personal and institutional benefits of collaborative working. Consideration may need to be given to library staff structures and roles if these benefits are to be maximized and sustained.

Conflict of Interest Disclosure Policies and Practices in Peer-reviewed Biomedical Journals.

OBJECTIVE: We undertook this investigation to characterize conflict of interest (COI) policies of biomedical journals with respect to authors, peer-reviewers, and editors, and to ascertain what information about COI disclosures is publicly available. METHODS: We performed a cross-sectional survey of a convenience sample of 135 editors of peer-reviewed biomedical journals that publish original research. We chose an international selection of general and specialty medical journals that publish in English. Selection was based on journal impact factor, and the recommendations of experts in the field. We developed and pilot tested a 3-part web-based survey. The survey included questions about the presence of specific policies for authors, peer-reviewers, and editors, specific restrictions on authors, peer-reviewers, and editors based on COI, and the public availability of these disclosures. Editors were contacted a minimum of 3 times. RESULTS: The response rate for the survey was 91 (67%) of 135, and 85 (93%) of 91 journals reported having an author COI policy. Ten (11%) journals reported that they restrict author submissions based on COI (e.g., drug company authors' papers on their products are not accepted). While 77% report collecting COI information on all author submissions, only 57% publish all author disclosures. A minority of journals report having a specific policy on peer-reviewer 46% (42/91) or editor COI 40% (36/91); among these, 25% and 31% of journals state that they require recusal of peer-reviewers and editors if they report a COI. Only 3% of respondents publish COI disclosures of peer-reviewers, and 12% publish editor COI disclosures, while 11% and 24%, respectively, reported that this information is available upon request. CONCLUSION: Many more journals have a policy regarding COI for authors than they do for peer-reviewers or editors. Even author COI policies are variable, depending on the type of manuscript submitted. The COI information that is collected by journals is often not published; the extent to which such "secret disclosure" may impact the integrity of the journal or the published work is not known.

Optimal CINAHL search strategies for identifying therapy studies and review articles.

PURPOSE: To design optimal search strategies for locating sound therapy studies and review articles in CiNAHL in the year 2000. DESIGN AND METHODS: An analytic survey was conducted, comparing hand searches of 75 journals with retrievals from CINAHL for 5,020 candidate search terms and 17,900 combinations for therapy and 5,977 combinations for review articles. All articles were rated with purpose and quality indicators. Candidate search strategies were used in CINAHL, and the retrievals were compared with results of the hand searches. The proposed search strategies were treated as "diagnostic tests" for sound studies and the manual review of the literature was treated as the "gold standard." Operating characteristics of the search strategies were calculated. FINDINGS: Of the 1,383 articles about treatment, 506 (36.6%) met basic criteria for scientific merit and 127 (17.9%) of the 711 articles classified as a review met the criteria for systematic reviews. For locating sound treatment studies, a three-term strategy maximized sensitivity at 99.4% but with compromised specificity at 58.3%, and a two-term strategy maximized specificity at 98.5% but with compromised sensitivity at 52.0%. For detecting systematic reviews, a three-term strategy maximized sensitivity at 91.3% while keeping specificity high at 95.4%, and a single-term strategy maximized specificity at 99.6% but with compromised sensitivity at 42.5%. Three-term search strategies optimizing sensitivity and specificity achieved these values over 91% for detecting sound treatment studies and over 76% for detecting systematic reviews. CONCLUSIONS: Search strategies combining indexing terms and text words can achieve high sensitivity and specificity for retrieving sound treatment studies and review articles in CINAHL.

Nurse practitioner peer review: process and evaluation.

PURPOSE: To describe the initiation and evaluation of a nurse practitioner (NP) peer review program for a group of 15 NPs practicing at a Veteran's Affairs Medical Center. DATA SOURCES: Using a standardized review form, 15 NPs performed a peer review on a total of 163 medical records; each review was re-reviewed by 2 researchers who were also NPs. To determine the congruency of the reviews among the 15 NPs, the data were analyzed with Intraclass correlations (ICC) and ANOVA. CONCLUSIONS: A relatively low ICC (r = 0.37) was found for the 15 NPs. The ANOVA indicated that there were significant differences among the NPs (F = 11.92, p < .0001). IMPLICATIONS FOR PRACTICE: The outcome of a peer review process depends upon the motivation and values of the NPs, practice sites, and standardization of the format, as well as the degree of collective participation. Peer review can reveal charting deficiencies as well as identify topics for continuing education and risk management programs.

Computerized decision support for concurrent utilization review using the HELP system.

OBJECTIVE: Development and evaluation of computerized concurrent utilization review (UR) support taking advantage of a clinically rich computerized patient database. DESIGN: The Automated Support System for Utilization Review (ASSURE) applies the Appropriateness Evaluation Protocol (AEP) Day of Care criteria to computerized patient data in the HELP hospital information system. This paper reports the development, verification, and validation of ASSURE. MEASUREMENTS: Implementation correctness was verified by measuring agreement with a nurse reviewer, using separate sample sets for all 20 criteria for a total of 560 current inpatients. Usefulness in detecting inappropriate days of care was validated by two nurse reviewers who were crossed with manual and computer-assisted review methods in a blocked design for 168 current inpatients. Agreement with reviewers, sensitivity, specificity, positive predictive value, and negative predictive value were measured. RESULTS: Agreement was very good for satisfaction of criteria, and good for appropriateness of day of care. A patient day identified by ASSURE as potentially inappropriate would be twice as likely to be judged inappropriate by a reviewer as a randomly selected patient day. Review of the 10% of patient days identified as potentially inappropriate by ASSURE would identify approximately 21% of the inappropriate days of care. CONCLUSION: ASSURE is a clinically useful tool for screening adult acute care patients for inappropriate days of care, and promises to make a major contribution to reducing health care costs. The prognosis for successful routine clinical use is good.

Global priority setting for Cochrane systematic reviews of health promotion and public health research.

BACKGROUND: Systematic reviews of health promotion and public health interventions are increasingly being conducted to assist public policy decision making. Many intra-country initiatives have been established to conduct systematic reviews in their relevant public health areas. The Cochrane Collaboration, an international organisation established to conduct and publish systematic reviews of healthcare interventions, is committed to high quality reviews that are regularly updated, published electronically, and meeting the needs of the consumers. AIMS: To identify global priorities for Cochrane systematic reviews of public health topics. METHODS: Systematic reviews of public health interventions were identified and mapped against global health risks. Global health organisations were engaged and nominated policy-urgent titles, evidence based selection criteria were applied to set priorities. RESULTS: 26 priority systematic review titles were identified, addressing interventions such as community building activities, pre-natal and early infancy psychosocial outcomes, and improving the nutrition status of refugee and displaced populations. DISCUSSION: The 26 priority titles provide an opportunity for potential reviewers and indeed, the Cochrane Collaboration as a whole, to address the previously unmet needs of global health policy and research agencies.

Characteristics and quality of systematic reviews of acupuncture, herbal medicines, and homeopathy.

BACKGROUND: We aimed to describe the approaches and characteristics of systematic reviews on three major complementary therapies and to assess their methodological quality. METHODS: Systematic reviews of clinical trials of acupuncture, herbal medicines, and homeopathy were identified from a database developed for the Cochrane Collaboration Complementary Medicine Field. Information on conditions, interventions, methods, results, and conclusions was extracted using a pre-tested form; methodological quality was assessed using the Oxman scale. RESULTS: 115 reviews were included (39 on acupuncture, 58 on herbal medicine, 18 on homeopathy). Research questions were most specific in herbal medicine, and tended to be very general in homeopathy. The main comparison in most reviews was with placebo. The methodological quality of reviews was highly variable. Deficiencies were most frequent for the description of the selection process and the summary of the results of primary studies. CONCLUSION: Systematic reviews tend to approach different complementary therapies in different manner. Compared to a set of reviews on analgesic interventions methodological quality was slightly better on the average, but there is ample room for improvement in future complementary medicine reviews.

Prospective peer review in fine needle aspiration cytology. Another step toward quality assurance.

OBJECTIVE: To analyze the effects of a prospective peer review program on diagnostic accuracy in a routine cytopathology laboratory. STUDY DESIGN: For the study, 4,836 consecutive cases subjected to fine needle aspiration cytology (FNAC) over a one-year period were used. Nine pathologists performed both reporting and peer review functions. Disagreements were classified into "diagnostic errors" and "diagnostic discrepancies," depending on their impact on patient care. The effect of this review on turnaround time was statistically analyzed. A retrospective review of 4,025 cases from the preceding year was performed for comparison. RESULTS: Sixty-six cases with diagnostic disagreements were detected by prospective review. There were 28 diagnostic errors and 38 diagnostic discrepancies. The initial turnaround time for diagnostic FNAC in 90% of total cases was < 24 hours; mean delay for the remainder was 3.3 days. Prospective peer review added a further delay of 1 and 1.5 days, respectively. The number of diagnostic disagreements was significantly higher in the retrospective review (P < .01). CONCLUSION: Prospective peer review of diagnostic FNAC resulted in improved accuracy of diagnosis and reduced potential for inappropriate therapy; however, turnaround time was significantly increased.
