A review of medical education and medical informatics

Physicians have considerable difficulty collecting and interpreting information from patients, dealing with the uncertainties associated with diagnosing and treating their patients, communicating precisely with one another, keeping up to date, and applying recommended procedures when indicated. Some of the advances in information technology may help physicians to manage information more effectively through more accessible, validated clinical indexes, data bases of diagnostic test characteristics, computerized audits of clinical activities with feedback, expert systems, on-line access to the medical literature, and other tools of medical informatics. Medical educators can catalyze this process by facilitating the introduction of information technology into academic clinical settings so that students can learn its use first-hand and by promoting the evolution of this and other aspects of medical informatics, a new discipline dedicated to the solution of information problems in health care. The potential roles for computer-aided instruction and centralized computer laboratories in medical schools are much less clear.     

IMIA Working Group 13: organizational impact of medical informatics

In 1993 the International Medical Informatics Association approved a working group whose purpose focused on the people and organizational issues surrounding the use of computers in health care. This article outlines two key concepts that act as the guiding principles for the working group's efforts. The concepts are: applying the knowledge of human behaviors toward the use of information or information technology within a health care environment and effectively incorporating human factors, culture, change, and organizational and human engineering in the medical informatics processes. These concepts are further supported by functional statements and a strategy to ensure the principles are effectively diffused in the medical informatics community. The concepts, functional statements and process were adopted by the working group and are outlined in this article.     

Wavelets and imaging informatics: a review of the literature

Modern medicine is a field that has been revolutionized by the emergence of computer and imaging technology. It is increasingly difficult, however, to manage the ever-growing enormous amount of medical imaging information available in digital formats. Numerous techniques have been developed to make the imaging information more easily accessible and to perform analysis automatically. Among these techniques, wavelet transforms have proven prominently useful not only for biomedical imaging but also for signal and image processing in general. Wavelet transforms decompose a signal into frequency bands, the width of which are determined by a dyadic scheme. This particular way of dividing frequency bands matches the statistical properties of most images very well. During the past decade, there has been active research in applying wavelets to various aspects of imaging informatics, including compression, enhancements, analysis, classification, and retrieval. This review represents a survey of the most significant practical and theoretical advances in the field of wavelet-based imaging informatics.     

The impact of gender on medical visit communication and patient satisfaction within the Japanese primary care context

Objective

This study was designed to address significant gaps in the predominantly western-centric research literature by examining the influence of gender concordance in medical communication and patient satisfaction within the Japanese context.

Factors influencing patient education in shared medical appointments: Integrative literature review

ObjectiveThis integrative literature review investigates the factors influencing patient education in Shared Medical Appointments.MethodsFollowing template analysis method, we used key concepts of the Social Cognitive Theory (SCT) and Social Constructivism as a priori themes. After detailed analysis of the included studies, we deduced subthemes, forming a final template. Based on this final template, we analysed our data again as a final check.ResultsWe included 22 studies. We found that the factors feeling of bonding, humour, feeling of safety, access to information, time, relationship participants-staff, modelling and self-regulation influence the education of SMA participants. Furthermore, we found that health care providers function both as leaders and peers.ConclusionWe found eight factors that influence the education of SMA participants. Health care providers exert influence on these factors, but in turn, they are also influenced by them in their transfer of knowledge.Practice implicationsIn order to create a climate of learning and to promote transfer of knowledge, these eight factors should be considered. Health care providers should be aware of their roles and they might need some extra skills for their leadership roles. This can also lead to practical implications for the curriculum in medical schools.     

Arthritis patient education: A review of the literature

Arthritis in one of the most prevalent chronic diseases and the number one disabler of the elderly. Even though arthritis is a major cause of morbidity and a contributor to early mortality, relatively few studies have been undertaken to examine effects of arthritis patient education. This review was undertaken to (1) provide a summary of arthritis patient education studies, (2) summarize the effectiveness of arthritis patient education in changing knowledge, behavior, psychological status, and health status, (3) address critical issues/problems in arthritis patient education study methodology, and (4) suggest guidelines for future design, implementation, and evaluation of arthritis patient education programs. In addition, we discuss implications of past studies for future practice.     

The impact of hormones on menopausal sexuality: a literature review

Menopause is associated with physiological and psychological changes that influence sexuality. During menopause, the primary biological change is a decrease in circulating estrogen levels. Estrogen deficiency initially accounts for altered bleeding and diminished vaginal lubrication. Continual estrogen loss often leads to numerous signs and symptoms, including changes in the vascular and urogenital systems. Alterations in mood, sleep, and cognitive functioning are common as well. These changes may contribute to lower self-esteem, poorer self-image, and diminished sexual responsiveness and sexual desire. Other important nonhormonal factors that affect sexuality are health status and current medications, changes in or dissatisfaction with the partner relationship, social status, and cultural attitudes toward older women. The problems in sexual functioning related to estrogen deficiency can be treated with hormone therapy that includes estrogens alone and estrogens combined with androgens. Vaginal lubricants and moisturizers also may be useful in ameliorating postmenopausal sexual complaints. This article reviews the literature on the impact of menopausal estrogen loss on sexuality and on the effect of hormone therapy on sexual function during menopause.     

Evaluating informatics applications--clinical decision support systems literature review.

This paper reviews clinical decision support systems (CDSS) literature, with a focus on evaluation. The literature indicates a general consensus that clinical decision support systems are thought to have the potential to improve care. Evidence is more equivocal for guidelines and for systems to aid physicians with diagnosis. There also is general consensus that a variety of systems are little used despite demonstrated or potential benefits. In the evaluation literature, the main emphasis is on how clinical performance changes. Most studies use an experimental or randomized controlled clinical trials design (RCT) to assess system performance or to focus on changes in clinical performance that could affect patient care. Few studies involve field tests of a CDSS and almost none use a naturalistic design in routine clinical settings with real patients. In addition, there is little theoretical discussion, although papers are permeated by a rationalist perspective that excludes contextual issues related to how and why systems are used. The studies mostly concern physicians rather than other clinicians. Further, CDSS evaluation studies appear to be insulated from evaluations of other informatics applications. Consequently, there is a lack of information useful for understanding why CDSSs may or may not be effective, resulting in making less informed decisions about these technologies and, by extension, other medical informatics applications.     

The impact of gender dyads on doctor–patient communication: A systematic review

Objective

Systematic review of evidence about the impact of gender dyads on clinician–patient communication.

Methods

Search of Medline, CINAHL and PsychINFO (1960–2007) and the British Library of grey literature, and hand searching of Patient Education and Counselling and Social Science and Medicine (2005–2007), returning 648 articles. Ten studies met all inclusion criteria.

Results

Gender dyads influenced the patient agendas elicited, talk content, communication style, non-verbal communication, the exhibition of power, and consultation length. Consultation length was studied and affected by gender dyads more frequently than any other phenomenon. Distinctive differences between the dyads were identified, largely as expected, but with some surprises. For example, female/female dyads were the most patient-centred, and had longer consultations containing the most talk. However they also contained the most bio-medical talk.

Conclusion

The evidence base is small, and a more rigorous approach to reporting quality indicators is needed. However, observed dyad differences may provide different opportunities for effective communication and clinical outcomes for patients. Further research with a primary focus on gender dyad effects is needed to test this.

Practice implications

Findings have implications for policy, healthcare organisations, and individual doctors alike, raising awareness about workforce issues and communication skills training needs in particular.     

Cultural differences in medical communication: A review of the literature

ObjectiveCulture and ethnicity have often been cited as barriers in establishing an effective and satisfying doctor–patient relationship. The aim of this paper is to gain more insight in intercultural medical communication difficulties by reviewing observational studies on intercultural doctor–patient communication. In addition, a research model for studying this topic in future research is proposed.MethodsA literature review using online databases (Pubmed, Psychlit) was performed.ResultsFindings reveal major differences in doctor–patient communication as a consequence of patients’ ethnic backgrounds. Doctors behave less affectively when interacting with ethnic minority patients compared to White patients. Ethnic minority patients themselves are also less verbally expressive; they seem to be less assertive and affective during the medical encounter than White patients.ConclusionMost reviewed studies did not relate communication behaviour to possible antecedent culture-related variables, nor did they assess the effect of cultural variations in doctor–patient communication on outcomes, leaving us in the dark about reasons for and consequences of differences in intercultural medical communication. Five key predictors of culture-related communication problems are identified in the literature: (1) cultural differences in explanatory models of health and illness; (2) differences in cultural values; (3) cultural differences in patients’ preferences for doctor–patient relationships; (4) racism/perceptual biases; (5) linguistic barriers. It is concluded that by incorporating these variables into a research model future research on this topic can be enhanced, both from a theoretical and a methodological perspective.Practice implicationsUsing a cultural sensitive approach in medical communication is recommended.     

The impact of patient and physician computer mediated communication skill training on reported communication and patient satisfaction

Objective

The objective was to evaluate parallel patient and physician computer-mediated communication skill training on participants’ report of skill use and patient satisfaction.

Methods

Separate patient and clinician web-tools comprised of over 500, 10-s video clips demonstrating patient-centered skills in various ways. Four clinician members of the American Academy of Family Physicians National Research Network participated by enrolling 194 patients into a randomized patient trial and 29 physicians into a non-randomized clinician trial of respective interventions. All participants completed baseline and follow-up self-report measures of visit communication and satisfaction.

Results

Intervention patients reported using more skills than controls in five of six skill areas, including identification of problems/concerns, information exchange, treatment adherence, shared decision-making and interpersonal rapport (all p < .05); post intervention, physicians reported using more skills in the same 5 areas (all p < .01). Intervention group patients reported higher levels of satisfaction than controls in five of six domains (all p < .05).

Conclusion

Communication skill training delivered in a computer mediated format had a positive and parallel impact on both patient and clinician reported use of patient-centered communication and in patient satisfaction.

Practice Implications

Computer-mediated interventions are cost and time effective thereby increasing patient and clinician willingness to undertake training.     

The impact of residents sitting at the bedside on patient satisfaction during team rounds

ObjectivesPatient satisfaction ratings are a priority for academic medical centers. Sitting during patient encounters has been recommended as a “best practice.”¹ A prior study showed that hospitalists had higher-rated communication skills when sitting compared to standing at the bedside during rounds.² It is unclear whether the same is true of resident-led team rounds.MethodsWe performed a cluster-randomized crossover trial assigning 18 internal medicine residents to sit or stand at the bedside during rounds.ResultsA total of 347 patients were surveyed to assess physician communication skills. Standing residents received higher ratings than sitting residents on 2 of 5 survey items and rounding duration did not differ. These results differ from prior work that suggests sitting is superior to standing^2–6.ConclusionWe suspect that one rounding member sitting, while all others stand, is not enough to impact patients’ perceptions. These results suggest that initiatives to optimize patient satisfaction on resident-staffed units should be focused elsewhere.Practice implicationsPatients do not have better impressions of physician communication skills when one team member is sitting and the rest are standing.     

The evolution of medical informatics in China: A retrospective study and lessons learned

BackgroundIn contrast to China’s giant health information technology (HIT) market and tremendous investments in hospital information systems the contributions of Chinese scholars in medical informatics to the global community are very limited. China would like to have a more important position in the global medical informatics community.ObjectiveA better understanding of the differences between medical informatics research and education in China and the discipline that emerged abroad will better inform Chinese scholars to develop right strategies to advance the field in China and help identify an appropriate means to collaborate more closely with medical informatics scholars globally.MethodFor the first time, this paper divides the evolution of medical informatics in China into four stages based on changes in the core content of research, the educational orientation and other developmental characteristics. The four stages are infancy, incubation, primary establishment and formal establishment. This paper summarizes and reviews major supporting journals and publications, as well as major organizations. Finally, we analyze the main problems that exist in the current disciplinary development in China related to medical informatics research and education and offer suggestions for future improvement.ConclusionsThe evolution of medical informatics shows a strong and traditional concentration on medical library/bibliographic information rather than medical (hospital information or patient information) information. Misdirected-concentration, a lack of formal medical informatics trained teaching staff and mistakenly positioning medical informatics as an undergraduate discipline are some of the problems inhibiting the development of medical informatics in China. These lessons should be shared and learned for the global community.     

A systematic review of the literature reporting on studies that examined the impact of interactive, computer-based patient education programs

Objective

To evaluate studies that examined the impact of interactive, computer-based education (ICBE) programs on patient education.

Methods

The Medline and CINAHL databases were searched to identify randomized controlled studies that evaluated the impact of ICBE programs.

Results

The 25 studies that met the selection criteria generally supported the ability of ICBE programs to promote knowledge gains. Results related to economic or clinical outcomes were less consistent. Significant variations were noted across studies in program features, implementation and integration strategies, and in comparison program attributes and quality. It is likely that these differences contributed to the disparity in findings across studies.

Conclusion

Although significant inconsistencies in results were noted, the research provided collective evidence that ICBE programs had the potential to add great value to the patient education process. Programs must be properly designed and implementation and integration processes effectively planned in order to achieve consistently positive outcomes.

Practice implications

Consideration of the “best practices” derived from the research and noted in this report will assist healthcare providers in designing, selecting, and implementing effective ICBE programs.     

The impact on mental health practitioners of the death of a patient by suicide: A systematic review

There is a growing body of research investigating the impact on mental health professionals of losing a patient through suicide. However, the nature and extent of the impact is unclear. This systematic review synthesizes both quantitative and qualitative studies in the area. The aim was to review the literature on the impact of losing a patient through suicide with respect to both personal and professional practice responses as well as the support received. A search of the major psychological and medical databases was conducted, using keywords including suicide, patient, practitioner, and impact, which yielded 3,942 records. Fifty-four studies were included in the final narrative synthesis. Most common personal reactions in qualitative studies included guilt, shock, sadness, anger, and blame. Impact on professional practice included self-doubt and being more cautious and defensive in the management of suicide risk. As quantitative study methodologies were heterogeneous, it was difficult to make direct comparisons across studies. However, 13 studies (total n = 717 practitioners) utilized the Impact of Event Scale, finding that between 12% and 53% of practitioners recorded clinically significant scores. The need for training that is focused on the impact of suicides, and the value placed upon informal support was often cited. The experience of losing a patient through suicide can have a significant impact on mental health professionals, both in terms of their personal reactions and subsequent changes to professional practice. The negative impact, however, may be moderated by cultural and organisational factors and by the nature of support available.     

Current issues of medical informatics

Due to the modern high standards of information technologies it is only natural to promote our medical care and to ensure a new quality of clinical services. Information technologies should be introduced into the medical field with due respect to clearly predetermined principles. Analyzed in the paper are the key reasons for a huge number of problems occurring in the sphere of medical informatics; optimal methods of medical-informatics introduction are defined.     

The effects of telephone consultation and triage on healthcare use and patient satisfaction: a systematic review

BACKGROUND: In recent years there has been a growth in the use of the telephone consultation for healthcare problems. This has developed, in part, as a response to increased demand for GP and accident and emergency department care. AIM: To assess the effects of telephone consultation and triage on safety, service use, and patient satisfaction. DESIGN OF STUDY: We looked at randomised controlled trials, controlled studies, controlled before/after studies, and interrupted time series of telephone consultation or triage in a general healthcare setting. SETTING: All healthcare settings were included but the majority of studies were in primary care. METHOD: We searched the Cochrane Central Register of Controlled Trials, EPOC specialised register, PubMed, EMBASE, CINAHL, SIGLE, and the National Research Register and checked reference lists of identified studies and review articles. Two reviewers independently screened studies for inclusion, extracted data, and assessed study quality. RESULTS: Nine studies met our inclusion criteria: five randomised controlled trials; one controlled trial; and three interrupted time series. Six studies compared telephone consultation with normal care; four by a doctor, one by a nurse, and one by a clinic clerk. Three of five studies found a significant decrease in visits to GPs but two found an increase in return consultations. In general at least 50% (range = 25.5-72.2%) of calls were handled by telephone consultation alone. Of seven studies reporting accident and emergency department visits, six showed no difference between the groups and one--of nurse telephone consultation--found an increase. Two studies reported deaths and found no difference between nurse telephone consultation and normal care. CONCLUSIONS: Although telephone consultation appears to have the potential to reduce GP workload, questions remain about its effect on service use. Further rigorous evaluation is needed with emphasis on service use, safety, cost, and patient satisfaction.     

The impact of environmental contaminants on extracellular vesicles and their key molecular regulators: A literature and database-driven review

Exposure to environmental chemicals is now well recognized as a significant factor contributing to the global burden of disease; however, there remain critical gaps in understanding the types of biological mechanisms that link environmental chemicals to adverse health outcomes. One type of mechanism that remains understudied involves extracellular vesicles (EVs), representing small cell-derived particles capable of carrying molecular signals such as RNAs, miRNAs, proteins, lipids, and chemicals through biological fluids and imparting beneficial, neutral, or negative effects on target cells. In fact, evidence is just now starting to grow that supports the role of EVs in various disease etiologies. This review aims to (1) Provide a landscape of the current understanding of the functional relationship between EVs and environmental chemicals; (2) Summarize current knowledge of EV regulatory processes including production, packaging, and release; and (3) Conduct a database-driven analysis of known chemical–gene interactions to predict and prioritize environmentally relevant chemicals that may impact EV regulatory genes and thus EV regulatory processes. This approach to predicting environmentally relevant chemicals that may alter EVs provides a novel method for evidence-based hypothesis generation for future studies evaluating the link between environmental exposures and EVs.     

Treatment of Japanese cedar pollinosis and its impact on patient satisfaction]

Japanese cedar pollinosis is a major public health problem in Japan because of its severe symptom and high prevalence. However, patient satisfaction by treatment is poor according to current reports. As the treatments, pre-seasonal medication and single peroral anti-allergic drug on demand are frequently used in Japan. Against conventional methods, we treated 301 patients with Japanese cedar pollinosis by persistent use of combined drugs (topical steroid, peroral anti-allergic drug and eye drop) without pre-seasonal medication in 2003. Immunotherapy was also used in 90 patients treated. As a result, 97% of patients was satisfied in this treatment and immunotherapy contributed to reduction in the amount of drug and high treatment outcome.
