Interventions for helping patients to follow prescriptions for medications.

BACKGROUND BACKGROUND: Efforts to assist patients with adherence to prescribed, self-administered medications might improve the benefits and efficiency of health care. OBJECTIVES OBJECTIVE: To update an ongoing review summarising the results of randomised controlled trials (RCTs) of interventions to help patients follow prescriptions for medications, focusing on trials that measured both adherence and clinical outcomes. SEARCH STRATEGY: Computerised searches to July 1998 in MEDLINE, CINAHL, The Cochrane Library, International Pharmaceutical Abstracts (IPA), PsychInfo, Sociofile, and HSTAR; bibliographies in articles on patient adherence; articles in the reviewers' personal collections; and contact with authors. SELECTION CRITERIA: Articles were selected if they reported an unconfounded RCT of an intervention to improve adherence with prescribed medications, measuring both medication adherence and treatment outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive initial findings. DATA COLLECTION AND ANALYSIS: Information on study design features, interventions and controls, and findings were extracted by one reviewer (PM) and a research assistant and confirmed by two of the other reviewers. The studies were too disparate to warrant meta-analysis. MAIN RESULTS: For short-term treatments, one study, of counselling and written information, showed an effect on adherence and clinical outcome. Ten of 19 interventions for long-term treatments reported in 17 RCTs were associated with improvements in adherence, but only nine interventions led to improvements in treatment outcomes. Almost all of the interventions that were effective for long-term care were complex, including combinations of more convenient care, information, counselling, reminders, self-monitoring, reinforcement, family therapy, and other forms of additional supervision or attention. Even the most effective interventions did not lead to large improvements in adherence and treatment outcomes. Two studies showed that telling patients about adverse effects of treatment did not affect their adherence. REVIEWER'S CONCLUSIONS: The full benefits of medications cannot be realised at currently achievable levels of adherence. Current methods of improving adherence for chronic health problems are mostly complex and not very effective. More studies of innovative approaches to assist patients to follow medication prescriptions are needed.

The prevalence and incidence of medical conditions in healthy pharmaceutical company employees who volunteer to participate in medical research.

AIMS: Although clinical research in healthy volunteers is commonly performed there have been few studies of the value of the medical screening of subjects. The aim of this study was to investigate the prevalence and incidence of medical conditions found during the medical screening of 'healthy' subjects employed in a pharmaceutical company who volunteered to participate in medical research. METHODS: This was a retrospective study of the medical notes of all the subjects who volunteered for membership of the Zeneca Clinical Pharmacology Unit's healthy volunteer panel over a 4 year period from 1990 to 1994. The prevalence of medical conditions found at presentation was determined. The incidence of medical conditions during the 4 year observation period was also ascertained. Medical screening included a full medical history and examination, clinical chemistry, haematology and urinalysis screens, pulmonary function tests, ECGs, 24 h ambulatory cardiac monitoring and a request for information from the volunteer's General Practitioner. RESULTS: Prevalence-1293 subjects volunteered to join the panel of which 156 subjects (12%) were not accepted at presentation including 141 (10. 9%) for medical reasons. The most medical common reasons were; previously diagnosed medical conditions (3.3%), cardiovascular abnormalities (1.9%), abnormal liver function tests (1.9%), anaemia (1.2%), hyperlipidaemia (1.1%), excess alcohol intake (0.6%) and thyroid disease (0.5%). Incidence-36 of the 1137 volunteers (0.8% per year) accepted onto the panel subsequently developed medical conditions of which the most common were; anaemia (0.29% per year), cardiovascular abnormalities (0.13% per year) and vasovagal syncope (0.13% per year). CONCLUSIONS: This study demonstrates the importance of medical screening before healthy volunteers participate in clinical research.

The impact of dedicated medication nurses on the medication administration error rate: a randomized controlled trial.

BACKGROUND: Concerns about hospital medication safety mount as the pace of new drug releases accelerates. METHODS: We performed a randomized study at 2 hospitals (A and B) to examine whether the medication administration error rate could be decreased by having "dedicated" nurses focus exclusively on administering drugs. "Medication nurses," after receiving a brief review course on safe medication use, were responsible solely for drug delivery for up to 18 patients each. "General nurses," who did not attend the course, provided comprehensive care, including drug delivery, for 6 patients each. A direct observation technique was used to record drug errors, process-variation errors, and total errors. RESULTS: At both hospitals combined, the total error rate was 15.7% for medication nurses and 14.9% for general nurses (P<.84). Comparing hospitals, the total error rate for medication nurses at hospital B was significantly higher than it was at hospital A (19.7% vs 11.2%; P<.04). At hospital A, there was a significantly lower error rate for medication nurses than for general nurses in the surgical units (P<.01) but no significant differences in total errors comparing nurse types in the medical units (P<.77). CONCLUSIONS: This trial suggests that use of dedicated medication nurses does not reduce medication error rates. However, subgroup analysis indicates that medication nurses might be useful in some settings. The differences in findings at the 2 hospitals and their differences in medication-use processes reinforce the concept that medication errors are usually related to systems design issues.

U.S. citizens who graduated from medical schools outside the United States and Canada and received certification from the Educational Commission for Foreign Medical Graduates, 1983-2002.

PURPOSE: To provide a descriptive overview of international medical school graduates (IMGs), U.S. and non-U.S. citizens, who obtained their medical degrees outside of the United States and Canada, with a focus on where U.S. citizens received their medical education and how this choice has changed over time. METHOD: The study group included all IMGs (n = 143,926) certified by the Educational Commission for Foreign Medical Graduates (ECFMG) from 1983-2002. Descriptive statistics were calculated, including historical certification rates for non-U.S. citizen and U.S. citizen IMGs. For IMGs who were U.S. citizens (n = 18,762), the data were summarized by medical school and country of medical school. RESULTS: U.S. citizens who attended medical schools abroad were more likely to attend schools in Central America and the Caribbean than in any other geographic region. There was a steady decrease in the number of U.S. citizens graduating from European medical schools. Conversely, the number graduating from medical schools in India and Israel rose. Over the period studied, the regions of Africa, Oceania, and South America graduated relatively few U.S. citizens. CONCLUSIONS: From 1983-2002, U.S. citizens graduated from medical schools in Central America and the Caribbean more than any other geographic region. Studying the characteristics of medical schools in this region and their similarities to U.S. medical schools, such as a four-year curriculum, may explain why U.S. citizens are attracted to this region in large numbers. Additional studies focusing on the characteristics of medical schools that train IMGs, the performance of the graduates, and their posttraining practice patterns are warranted.

[Committee for Human Rights and Medical Ethics of the Croatian Medical Association].

The historical development of ethical standards and institutions of Croatian Medical Association is presented. The first standards were "Medical order and Community" in 1895 and the ethical codex under the name "Main principles of Medical dignity" in 1901 resp. 1921. According to the new Association's Statute in 1990 the first "Committee on Human Rights and Medical Ethics" was founded. Since 1995 the Committee operates as a common "Committee on Medical Ethics and Deontology" of Croatian Medical Association and of Croatian Medical Chamber. In short the activities of committees in both periods, 1991-1995 and 1995-1999 are presented, including the establishing of a new "Codex of Medical Ethics". Since 1999 the Croatian Medical Chamber divorced the cooperation with Croatian Medical Association and founded his own Committee. The Croatian Medical Association is now without ethical committee. The establishment of a new, common Committee of the Medical Association, Medical Chamber and Universities is suggested.

Dynamic viewer of medical events in electronic medical record.

Medical record should enable doctors to comprehend the patient's history and select suitable medical treatment. In paper based medical records, medical events (examination, treatment etc.) are recorded successively, and problem oriented recording is difficult to be applied to patients with much information and a long history. Consequently it is not easy to understand the patient's history from paper based medical records. In order to solve this problem, we developed the flow sheet system in our electronic medical record (EMR). To make a flow sheet, we analyzed the structure of the medical event data. In this paper we introduced the medical event information model for our EMR. Furthermore, we clarified the specification of the data presentation on the flow sheet. We developed the flow sheet on the basis of these analyses. Because there are 3 layers in the vertical axis of the flow sheet, many items of the medical event can be displayed on the screen. When user clicks the cell, the corresponding detail data including images are shown. This system functions to link medical event items with a problem, and shows the bundled items on the flow sheet when the user selects the problem. We implemented this system in Osaka University Hospital. The number of the types of medical events and those of detail events in inpatients are 5.0+1.7 (mean+SD) and 60+47, respectively. The medical doctors in Osaka University Hospital evaluated this system, and concludes that the flow sheet data presentation makes comprehension of the patient's history easier than paper based records. As to the function of bundling the items relevant to the problem, they feel it is especially useful for patients with chronic disease. Thus the flow sheet data presentation in EMR is useful for medical practice.

Critique of medical history education in Turkey's medical faculties.

In this article the curricula at the baccalaureate level of 18 medical faculties in our country that have Deontology-Medical Ethics and Medical History departments have been evaluated and classified, looking at the number of hours and topics. Our purpose for this study was, particularly from the aspect of medical history, to compare curricula in departments in which this class is given, to display shared and different directions, and to draw a general framework of medical history education in our country. The study was conducted between March and May 2004.A questionnaire with a total of 12 questions was sent by e-mail or fax to the related departments in the medical faculties. The data that were collected on the questionnaire included a) the year of foundation of the related department and the Medical Faculties that have Deontology-Medical History and Ethics Departments, b) the names of the faculties that have baccalaureate and doctoral programs, c) the number of teaching staff in these faculties, d) the length of medical history and ethics classes and their timing in semesters, e) the stated basic purpose and objectives of medical history classes, f) information about journals related to medical history in our country and g) organized ongoing medical history education. In this study qualitative and quantitative data were evaluated simultaneously, the purpose of medical history classes and the part that these classes play in developing the physicians' identity were assessed together with other results.

Meeting medical terminology needs--the Ontology-Enhanced Medical Concept Mapper.

This paper describes the development and testing of the Medical Concept Mapper, a tool designed to facilitate access to online medical information sources by providing users with appropriate medical search terms for their personal queries. Our system is valuable for patients whose knowledge of medical vocabularies is inadequate to find the desired information, and for medical experts who search for information outside their field of expertise. The Medical Concept Mapper maps synonyms and semantically related concepts to a user's query. The system is unique because it integrates our natural language processing tool, i.e., the Arizona (AZ) Noun Phraser, with human-created ontologies, the Unified Medical Language System (UMLS) and WordNet, and our computer generated Concept Space, into one system. Our unique contribution results from combining the UMLS Semantic Net with Concept Space in our deep semantic parsing (DSP) algorithm. This algorithm establishes a medical query context based on the UMLS Semantic Net, which allows Concept Space terms to be filtered so as to isolate related terms relevant to the query. We performed two user studies in which Medical Concept Mapper terms were compared against human experts' terms. We conclude that the AZ Noun Phraser is well suited to extract medical phrases from user queries, that WordNet is not well suited to provide strictly medical synonyms, that the UMLS Metathesaurus is well suited to provide medical synonyms, and that Concept Space is well suited to provide related medical terms, especially when these terms are limited by our DSP algorithm.

Scientific basis for the selection of emergency medical examination gloves for emergency medical technicians, paramedics, firefighters, and emergency department personnel. An update.

The use of powder-free natural rubber or latex-free emergency medical examination gloves is especially important to emergency medical technicians, paramedics, firefighters, and emergency department personnel to avoid eliciting an allergic reaction in the latex sensitized patient. The majority of our emergency medical technicians, paramedics, and firefighters are now wearing powder-free emergency medical examination gloves that comply with the stringent codes and standards established by the National Fire Protection Association (NFPA), while very few hospital emergency department personnel have been provided with NFPA-approved gloves. There are four well-defined goals of this report that will assist emergency medical services, fire departments, and hospitals in the selection and purchase of emergency medical examination gloves. First, we will review again the stringent regulations for emergency medical examination gloves that are outlined by the NFPA. This design and performance standard was devised by the NFPA to address protective clothing for emergency medical operations. The design and performance requirement of the emergency medical examination gloves were described in the NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 1997 Edition. As of September 2003, the emergency medical examination glove must meet the new design and performance requirements of emergency medical examination gloves discussed in NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 2003 Edition.

[History of medical ethics in Korea: focused on analysis of medical codes and covenants].

This article deals with the emergence of the codes of medical ethics and their change in Korean history. The modernized medical codes or covenants by the group of medical doctors has been made from the mid-twentieth century, although Korea has a long tradition of medical ethics, so called the Confucian medical ethics, Insul or Uido which were taken on very strong paternalistic characters. The history of the codes of medical ethics in contemporary Korea showed several revisions in 1961, 1965, 1979, and 1997 since the first establishment in 1955. Changes of political circumstances, the cultural level of the people, medical care system, and medical power leaded to the revisions. Throughout the revisions the codes or covenants of medical ethics in Korea has changed from simple translations of the codes by the World Medical Association and the American Medical Association to the reflexes of domestic medical situations; from the ones based on paternalistic doctor-patient relationship to more democratic ones; from the ones that only medical ethics were expressed to the ones that bioethics was expressed too.

Comparative analysis of knowledge, attitudes and perceptions about induced abortions among medical and non-medical students of Karachi.

OBJECTIVE: To determine the knowledge, attitudes and perceptions regarding induced abortions among university students of Karachi and compare these aspects among medical and non-medical students. STUDY DESIGN: Cross sectional opinion survey. METHODS: The study is a cross sectional opinion survey of medical and non-medical students from four educational institutions of Karachi using a pretested questionnaire. RESULTS: Of the 381 students interviewed, 201 were medical and 180 were non-medical. More medical students were aware of the correct definition of induced abortion. An encouraging finding was the awareness of our study population about the only legally acceptable circumstance for induced abortion in Pakistan, that is, if conceptus is a risk to maternal health (p<0.001). More medical students cited complications that were technical like uterine perforation (p<0.001), cervical trauma (p<0.001), DIC (p<0.001), and sepsis (p<0.001). More medical students thought induced abortion to be a health issue (p=0.001) as compared to non-medical students. Most of the medical students felt the need to modify Pakistan's law regarding abortion (p=0.008) especially for fetal anomalies (13.9%) and rape (7%). CONCLUSION: Though medical students were more knowledgeable about induced abortions as compared to the non-medical population, there is a need to improve awareness regarding induced and unsafe abortions and their consequences.

Pilot medical history and medications found in post mortem specimens from aviation accidents.

INTRODUCTION: Federal Aviation Administration (FAA) regulations require pilots to report all medications and medical conditions for review and consideration as to the overall suitability of the pilot for flight activities. METHODS: Specimens were collected by local pathologists from aviation accidents and sent to the Bioaeronautical Sciences Research Laboratory for analysis. The results of such tests were entered into the Forensic Case Management System. This database was searched to identify all pilots found positive for medications used to treat cardiovascular, psychological, or neurological conditions over the period January 1, 1993, through December 31, 2003. RESULTS: Toxicological evaluations were performed on 4143 pilots. Psychotropic drugs were found in 223 pilots. Cardiovascular medications were found in 149 pilots. Neurological medications were found in 15 pilots. Pilots reported psychological conditions in 14 of the 223 pilots found positive for psychotropic drugs. Only 1 of the 14 pilots reporting a psychological condition to the FAA reported the psychotropic medication found after the accident. Cardiovascular disease was reported by 69 of the pilots found with cardiovascular drugs in their system. Cardiovascular medications found in the pilots were reported by 29 of the 69 pilots reporting a cardiovascular condition. Only 1 of the 15 pilots reported having a neurological condition to the FAA; none of the pilots found with neurological medications reported the medication. CONCLUSIONS: Toxicology successfully identified 93% of the medications reported by the pilots. Pilots involved in fatal accidents taking psychotropic or neurological medications rarely reported the medication or their underlying medical condition to the FAA.

Medical history in the undergraduate medical curriculum.

History has long played a role in the education of American physicians, but the uses of medicine's past have changed over time. In the late nineteenth century, some physicians taught medical history to their students to supply a sense of continuity with professional traditions in times of rapid and bewildering change. Other physicians believed that instruction in medical history would impart a sense of refinement to medical practitioners. In the late twentieth century, medical history is increasingly viewed as a significant dimension of the professional, intellectual, and humanistic development of medical students. Further, it is one of the principal means by which recent, radical changes in health care can be given needed perspective. The knowledge that medicine and the medical sciences are fundamentally social enterprises is an important lesson for medical students. Through exposure to the history of health care, students also learn that medical knowledge is itself subject to change and is acquired in specific contexts. In the 1990s, medical history is taught in a variety of settings. In some schools, history is integrated into the teaching of medical humanities. Where medical history is institutionally distinct from the humanities, courses in medical history may be either elective or required. In order to reach students at every stage of their medical education, historians and clinicians can join forces to teach history in innovative and flexible programs.

Educational environment in traditional and innovative medical schools: a study in four undergraduate medical schools.

INTRODUCTION: The undergraduate curricula of medical schools in King Abdul Aziz University, Saudi Arabia, Umm Al-Qura University, Saudi Arabia and Sana'a University, Republic of Yemen are traditional, like most of the medical schools in the Middle East region. The curriculum in Dundee University Medical School, UK, claims to follow the prescriptions of the UK General Medical Council to be outcome based with three interlocking phases and students encouraged to take responsibility for their own learning. The aim of this study is to measure the educational environment, using the 50-item Dundee Ready Education Environment Measure (DREEM), in each medical school and to compare the educational environment as perceived by the responding students of the traditional medical schools in developing countries with that of the "modernised" medical school in Dundee University, UK. METHODS: The DREEM was administered to 1072 medical students in the four different universities. Using SPSS, data were expressed as means of scores. Comparisons between schools, years of study and gender were made using non-parametric tests. RESULTS: For all three traditional medical schools, the mean scores of the inventory were lower compared with Dundee Medical School. Students from traditional schools rated their learning and teaching environment significantly lower than their counterparts in Dundee Medical School. Similarly, they rated their academic self-perceptions, social-self perceptions and their atmosphere more poorly than the Dundee students. CONCLUSION: The DREEM provides useful diagnostic information about medical schools, whether it is in developing or western developed countries.

Effectiveness of a graduate medical education program for improving medical event reporting attitude and behavior.

OBJECTIVES: To evaluate the effectiveness of an educational program for improving medical event reporting attitude and behavior in the ambulatory care setting among graduate medical trainees. DESIGN: One group pre- and post-test study. SETTING: The University of Texas Southwestern Medical Center at Dallas Family Medicine Residency Program. PARTICIPANTS: All family practice residents (n = 30). INTERVENTION: Patient safety educational program implemented through an introductory lecture and 6 monthly conferences, June to December 2002, involving medical events that occurred in the ambulatory care setting. OUTCOME MEASURES: Medical event reporting attitude and behavior at baseline and at 6 month follow up, and barriers to medical event reporting at the 6 month follow up. RESULTS: Program attendance was significantly correlated with medical event reporting attitude and behavior change (rho = 0.525, p = 0.003). The median change in medical event reporting attitude and behavior was zero and not statistically significant (p = 0.566). Major barriers to medical event reporting were lack of time, extra paper work, and concern about career and personal reputation. CONCLUSIONS: Attending the patient safety educational program was key for promoting a positive medical event reporting attitude and behavior change among graduate trainees. Major barriers to medical event reporting were lack of time, extra paper work, and concern about career and personal reputation. Future research will need to focus on reducing these barriers and to evaluate the effectiveness of such a program over longer periods of time, since making a positive change in medical event reporting attitude and behavior must be made at the individual and organizational levels.

Medical costs attributed to depression among patients with a history of high medical expenses in a health maintenance organization.

BACKGROUND: While previous studies have compared medical utilization between depressed and nondepressed patients, we conducted a study that focused specifically on patients who had a history of high medical expenditures. METHODS: This study was designed to determine whether a positive screen for depression is predictive of continued high medical expenditures. Medical utilization data were obtained on 50,000 patients enrolled in the DeanCare health maintenance organization for 2 consecutive years. Consistent high utilizers were identified based on the medical utilization costs (paid by the health maintenance organization) for those 2 consecutive years, 1992 and 1993. A depression screen based on the Medical Outcomes Survey was mailed to 786 high utilizers. Their costs were determined for 1994. Regression analyses identified 1994 costs associated with depression, adjusting for age, sex, benefits package, and medical comorbidity. RESULTS: Depressed high utilizers were more likely than nondepressed high utilizers to have higher medical costs in 1994. Among high utilizers, depressed patients' 1994 costs were significantly higher ($5764 vs $4227; P < .001), although expenditures for depressed and nondepressed high utilizers were similar for the previous 2 years. The total medical cost associated with depression in 1994, adjusted for age, sex, benefits package, and medical comorbidity, was $1498 per patient. CONCLUSIONS: In the third year (1994), a positive Medical Outcomes Survey screen for depression in high utilizers was associated with $1498 in higher medical costs. The average actual amount spent on depression treatment accounted for only a small portion of total medical costs for depressed high utilizers in the third year.

Essential polyunsaturated fatty acid and lipid peroxide levels in never-medicated and medicated schizophrenia patients.

BACKGROUND: Reduced levels of membrane essential polyunsaturated fatty acids (EPUFAs) and increased levels of lipid peroxidation products (thiobarbituric acid reactive substances; TBARS) have been observed in chronic medicated schizophrenics. The relationship of EPUFA and TBARS to psychopathology is unclear, since their levels may be altered differentially by duration of illness and antipsychotic treatment. To minimize these confounds, their levels were compared among never-medicated patients in early illness, medicated patients and control subjects with similar lifestyle and common ethnic background. METHODS: RBC membrane EPUFAs, plasma TBARS, and various dimensions of psychopathology were measured using established procedures in never-medicated (n = 20) and medicated (n= 32) schizophrenia patients and in control subjects (n= 45). RESULTS: Reduced levels of EPUFAs, particularly arachidonic acid (AA) and docosahexaenoic acid (DHA), were found in never-medicated compared with control subjects; however, the reductions in levels of both AA and DHA were much smaller in medicated versus never-medicated patients; AA levels were similar to levels in control subjects. Only DHA levels were significantly reduced in medicated patients. Lower membrane AA levels were associated with increased levels of plasma TBARS in never-medicated patients. Lower levels of membrane EPUFAs and higher levels of plasma TBARS were associated with the severe symptoms in never-medicated versus medicated patients. CONCLUSIONS: Data indicate that reduced EPUFAs and increased TBARS exist in never-medicated patients, and these measures correlate with the severity of psychopathology indicating that the membrane EPUFA status may reflect the outcome of schizophrenia.

Using stated preference modeling to forecast the effect of medication attributes on prescriptions of alcoholism medications.

OBJECTIVE: The objective of this study was to forecast physicians' preferred rate of prescriptions of alcoholism medications given different medications attributes (i.e., efficacy, side effects, compliance, price, mode of administration, method of action). METHODS: Stated preference modeling was used. Data came from a survey of 1388 physicians specializing in addiction medication (65% response rate). Physicians were given four hypothetical scenarios, each in which they were asked to choose between prescribing one of two hypothetical alcoholism medications with given attributes or prescribing no medication. RESULTS: Prescribing decisions were elastic with respect to the efficacy of the medication (1.35 and 1.65 using two efficacy measures). A 10% increase in the percentage of patients who would remain abstinent on the medication would lead to a 13.5% increase in the percentage of patients prescribed the medication. Prescribing decisions were inelastic with respect of nonserious side effects (-0.24), compliance (0.80), and price (-0.25). The market share of alcoholism medications with extremely favorable characteristics (i.e., 80% abstinence rate, a 95% no heavy drinking rate, a 10% side effect rate, a 80% compliance rate, and a price of US dollars 0.25) was predicted to be 53%, and 47% of the population would not be prescribed a medication to prevent alcoholism. CONCLUSIONS: The market share of new medications to treat alcoholism among addiction specialists could surpass the low usage rates of existing medications if those medications have better attributes. However, prescription levels may not reach that expected for treatment of other diseases.
