Walking a mile in Grandma’s shoes - medical students’ evaluation of a very simple online aging game to enhance their understanding of older patients

Background

Aging simulation games are established educational interventions to make older patients’ perspectives noticeable, raise awareness about their needs, and positively influence attitudes toward older adults. Due to the COVID-19 pandemic restrictions imposed on education, we replaced a classroom-based aging simulation course with a simple online equivalent. This consisted of short introductory screencasts, four downloadable Portable Document Format (PDF) files containing issue-specific audio and video links, quizzes, case studies, and prompts for reflection. We explored how well our self-directed simple online simulation succeeded in providing students with relevant insights and experiences, raising awareness about age-related difficulties, and enhancing understanding of older patients.

Methods

In this cross-sectional study, an anonymous post hoc online survey was conducted among 277 5th-year medical students eligible for the course at the Leipzig University in May 2020. The questionnaire addressed overall course evaluations, assessments of the individual PDF components (working enjoyment, personal insights, professional learning gain, enhanced understanding, increased interest in working with older patients), and students’ main insights from the course (free text). Descriptive statistical and qualitative content analyses were performed.

Results

The response rate was 92.4% (n = 256, mean age 25.7 ± 3.4 years, 59.8% women). Nearly all respondents reported that the course was well structured, easily understandable, and that processing was intuitive. The majority (82.8%) perceived the course as practice-oriented, 88.3% enjoyed processing, 60.3% reported having gained new professional knowledge, and 75.4% had new personal insights. While only 14.8% agreed that the online course could generally replace the real-world simulation, 71.1% stated that it enabled them to change their perspective and 91.7% reported enhanced understanding of older patients. PDF components containing audio and video links directly imitating conditions (visual or hearing impairment) were rated highest. Qualitative data revealed manifold insights on the part of the students, most frequently referring to aspects of professional doctor-patient interaction, knowledge about conditions and diseases, role reversal, and enhanced empathy.

Conclusion

Simple online aging simulations may be suitable to provide students with relevant insights and enhance their understanding of older patients. Such simulations could be alternatively implemented in health professionals’ education where resources are limited.

Management and treatment of long COVID symptoms in general practices: An online-based survey

Independent from initial severity, many patients develop persistent symptoms after infection with SARS-CoV-2, described as long COVID syndrome. Most of these patients are treated by general practitioners (GPs). As evidence-based treatment recommendations are still sparse, GPs must make their therapy decisions under uncertainty. We investigated (1) the most frequently observed long COVID symptoms in general practices and (2) GPs' applied treatment and rehabilitation plans for these symptoms. In total, 143 German GPs participated in an online-based survey between 05/2021 and 07/2021. We found that each GP practice was treating on average 12 patients with long COVID symptoms. Most frequently seen symptoms were fatigue and reduced performance. Current therapy options were rated as poor and loss of smell and taste, fatigue, or lack of concentration were perceived to be especially difficult to treat. The use of drug and non-drug therapies and specialist referrals focused primarily on physiological and less on psychosomatic/psychological rehabilitation and followed guidelines of similar conditions. Our results provide first insights into how GPs approach a newly emerging condition in the absence of guidelines, evidence-based recommendations, or approved therapies, and might inform about GP preparedness in future pandemics. Our results also emphasize a gap between the current knowledge of the long COVID manifestation and knowledge about effective rehabilitation.

[General practitioners' perception of integrated care using communication technologies: a secondary analysis of a focus group of the Horizon 2020 funded project POLYCARE]

BACKGROUND

Integrated healthcare models (IC) have the objective of reducing the costs of an increased use of health service as well as the strong sectoral fragmentation of the German health care system. However, no national approach has been implemented in primary care to date.

METHOD

Ten GPs from the Cologne/Bonn district (60% male; Ø age = 52 years [35-65]) were invited to a focus group in 2016. The interview was part of the Horizon 2020 funded POLYCARE study. A semi-structured guideline was used to assess feasibility of the POLYCARE study protocol. GPs also provided information about previous experience with and attitudes toward IC models and the relevant information and communication technologies (ICT), such as home-monitoring or communication software. This information was analyzed using a transcending secondary analysis to evaluate conditions for their successful implementation.

RESULTS

Participants reported little experience with IC and ICT. However, they reported being open to both and seeing potential for time savings, better networking opportunities, and increased quality of care for their patients. The integration of social services was considered as a chance of alleviating the burden of socio-medical tasks. Barriers to the introduction of IC and ICT were seen in the initial time investment, the lack of legal structures, the concern about overabundant data, and the susceptibility to failure.

CONCLUSION

The nationwide expansion of social services as well as ICT that is easy to use, less susceptible to failure, and compatible with existing structures show great potential for relieving GPs. Future research should address the concerns - such as financial and time expenses of introducing IC and ICT - of GPs by systematic investigation in long-term studies. The provision of an additional legal basis that is regulating the respective remuneration models as well as the rights and obligations of all parties, IC and ICT can play a greater role in future patient care.

Workshop with medical students on physicians' earning opportunities, workload and job satisfaction increases the attractiveness of working self-employed and working in general practice

BACKGROUND

Among the various factors identified as relevant for primary care career choice, financial considerations have been consistently shown to have an impact. In Germany, reliable and easily understandable information on physicians' earning opportunities in self-employed settings is difficult to obtain for medical students, leading to substantial misperceptions that may negatively affect respective career considerations. This study investigated medical students' evaluation of a 45-min evidence-based workshop on earning opportunities, workload and job satisfaction in different specialties and settings to examine its effect on the perceived attractiveness of working self-employed and working in general practice.

METHODS

The workshop was implemented as part of a mandatory general practice clerkship in the fourth study year (of six). Post-hoc evaluations of all participants between October 2017 and September 2018 (one cohort) were analysed cross-sectionally including descriptive statistics, subgroup comparisons and qualitative analysis of free-text answers regarding students' main insights.

RESULTS

Response rate was 98.1% (307/313). Participants were on average 25.0 years old, and 68.3% were women. Based on a ten-point scale ranging from 1 = 'no influence' to 10 = 'very big influence', 91.9% confirmed at least some (> = 2) and 57.3% a rather high (> = 5) influence of earning expectations on their career choice process. Regarding the workshop, 86.1% were overall satisfied, and 89.5% indicated they had gained new insights, primarily regarding earning opportunities in different specialties and work settings, and frequently regarding job satisfaction, workload and the structure of revenues and expenditures in a doctor's office (according to qualitative analysis). In the opinion of 89.8% of students, the provided learning content should be part of the undergraduate curriculum. More than half of participants reported an increase regarding the attractiveness of working self-employed and working as a general practitioner, most frequently regarding earning opportunities, but also in general and in respect to job satisfaction, cost-benefit ratio and workload. This increase was significantly higher among students favouring or at least considering a general practice career.

CONCLUSIONS

The workshop and its content were appreciated by the students and showed clear potential to usefully complement undergraduate curricula aiming at increasing or reinforcing students' interest in working self-employed and working in general practice.

The Impact of the COVID-19 Pandemic on Avoidance of Health Care, Symptom Severity, and Mental Well-Being in Patients With Coronary Artery Disease

The COVID-19 pandemic affected regular health care for patients with chronic diseases. However, the impact of the pandemic on primary care for patients with coronary artery disease (CAD) who are enrolled in a structured disease management program (DMP) in Germany is not clear. We investigated whether the pandemic affected primary care and health outcomes of DMP-CAD patients (n = 750) by using a questionnaire assessing patients' utilization of medical care, CAD symptoms, as well as health behavior and mental health since March 2020. We found that out of concern about getting infected with COVID-19, 9.1% of the patients did not consult a medical practitioner despite having CAD symptoms. Perceived own influence on infection risk was lower and anxiety was higher in these patients compared to symptomatic CAD patients who consulted a physician. Among the patients who reported chest pain lasting longer than 30 min, one third did not consult a medical practitioner subsequently. These patients were generally more worried about COVID-19. Patients with at least one worsening CAD symptom (chest pain, dyspnea, perspiration, or nausea without apparent reason) since the pandemic showed more depressive symptoms, higher anxiety scores, and were less likely to consult a doctor despite having CAD symptoms out of fear of infection. Our results provide evidence that the majority of patients received sufficient medical care during the COVID-19 pandemic in Germany. However, one in ten patients could be considered particularly at risk for medical undersupply and adverse health outcomes. The perceived infection risk with COVID-19 might have facilitated the decision not to consult a medical doctor.

The PostStroke-Manager - combining mobile, digital and sensor-based technology with personal assistance: protocol of the feasibility study

INTRODUCTION

Post stroke management has moved into the focus as it represents the only way to secure acute treatment effects in the long term. Due to individual courses, post stroke management appears rather challenging and is hindered by existing barriers between treatment sectors. As a novel concept, the PostStroke-Manager combines digital and sensor-based technology with personal assistance to enable intersectoral cooperation, best possible reduction of stroke-related disability, optimal secondary prevention, and detection of physical and psychological comorbidities.

METHODS

This prospective single-center observational study aims to investigate the feasibility of the PostStroke-Manager concept in an outpatient setting. Ninety patients who have suffered an ischemic or hemorrhagic stroke or transient ischemic attack will be equipped with a tablet and mobile devices recording physical activity, blood pressure, and electrocardiographic signals. Through a server-based platform, patients will be connected with the primary care physician, a stroke pilot and, if necessary, other specialists who will use web-based platforms. Via the tablet, patients will have access to an application with 10 newly designed components including, for instance, a communication tool, medication schedule, medical records platform, and psychometric screenings (e.g., depression, anxiety symptoms, quality of life, adherence, cognitive impairment). During the 1-year follow-up period, clinical visits are scheduled at three-month intervals. In the interim, communication will be secured by an appropriate tool that includes text messenger, audio, and video telephony. As the primary endpoint, feasibility will be measured by a 14-item questionnaire that addresses digital components, technical support, and personal assistance. The PostStroke-Manager will be judged feasible if at least 50% of these aspects are rated positively by at least 75% of patients. Secondary endpoints include feedback from professionals and longitudinal analyses on clinical and psychometric parameters.

PERSPECTIVE

This study will answer the question of whether combined digital and personal support is a feasible approach to post stroke management. Furthermore, the patient perspective gained regarding digital support may help to specify future applications. This study will also provide information regarding the potential use of remote therapies and mobile devices in situations with limited face-to-face contacts.

Electric pulse heating device for the analysis of solid/solid phase transformations

Ohmic pulse heating is applied to investigate diffusion and interface controlled solid-state phase transformations. The developed device uses extensive solid-state electronics providing a high current, low voltage approach that overcomes the limitations of existing setups, most notably the use of sample geometries that allow for the reliable measurement of local temperatures and their assignment to microstructures. Power for heating is supplied by a capacitor array with adjustable voltage, and the process is controlled by microcontrollers and a solid-state relay, which allows for controlled pulses that are adjustable in microseconds. Electric currents of up to 22 kA at 90 V can be realized by the setup. Electric data are monitored and collected during the experiments, and temperature data are captured using a high-resolution infrared camera at high frame rates (1200 fps). The capabilities of the setup are demonstrated by rapid heating (10⁶ K/s) and subsequent cooling of a brass sample. Two distinct areas of the sample are analyzed in detail, showing similar heating, but different cooling curves with rates of 10⁴ and 10² K/s. Local microstructure analysis shows that different phase transformation mechanisms were dominant, and thus, the setup fulfills its purpose.

Phase Identification in Multi-Phase Cu-Zn/Cu-Al Alloys with Macroscopic Concentration Gradients

In order to study concentration invariant phase transitions in Cu-Zn-Al alloys which occur in a very narrow concentration range samples with concentration gradients were produced. Cylinders made of brass and Cu-Al bronze were joined by diffusion bonding and subsequently annealed. The samples exhibit multi-phase regions (α, β, γ1, martensite) with changing compositions and very different chemical properties. Standard techniques for the metallographic preparation of Cu alloys usually target specific phases within limited concentration ranges. To evaluate the microstructure, a two-stage chemical etching method using sodium hydroxide solution and subsequent selective colour etching was successfully used to gain an overview of the phases present in different areas along the concentration gradient. For the characterization of martensite, its birefringent optical properties were utilized. In polarized light, details of the martensitic structure are revealed which would otherwise only be accessible by scanning electron methods.

Medical students' perspectives on earning opportunities of self-employed physicians - realistic and relevant for the process of career choice?

BACKGROUND

Several studies report a substantial impact of financial considerations on the process of specialty choice and the willingness to establish one's own practice. In Germany, reliable information on self-employed physicians' earning opportunities is basically available, but not easily accessible and understandable for medical students. Misperceptions might contribute to recruitment problems in some fields, particularly in general practice. In order to identify a possible need for action, we investigated current German medical students' level of information regarding future earnings, and whether net earnings of general practitioners and other physicians working self-employed are estimated realistically. Additionally, we explored students' self-assessments regarding the extent of the impact of expected earnings on their personal career choice process.

METHODS

We conducted a cross-sectional questionnaire survey among fourth year (of six) medical students at one medical school (Leipzig). The participants estimated the net earnings of different physicians working self-employed. These estimations were compared with actual earnings data derived from a large German practice panel.

RESULTS

Response rate was 73.6% (231/314). The participants' mean age was 24.9 years and 59.1% were women. On a 10-point scale ranging from 1 = 'no influence' to 10='very big influence', 92.6% of the participants described at least some (≥2) influence of earning expectations on their career choice process, and 66.2% stated this influence to be 5 or higher. Every fourth student (26.4%) would rather or definitely reject a certain specialty because of expected low earning opportunities. While 60.4% had already thought about future earnings, only 26.8% had obtained concrete information. Compared with the data derived from the practice panel, the participants substantially underestimated the earning opportunities in self-employed settings, including general practice (median: 4500 vs. 6417€). However, depending on the single estimations, between 87.7 and 95.6% of the students stated they were 'rather uncertain' or 'very uncertain' regarding their estimations.

CONCLUSIONS

Despite confirming a relevant impact of financial considerations on career choice, German fourth year medical students are not well informed about earning opportunities in self-employed settings. Providing easily understandable information could enhance transparency and might help students to consider financial issues of career choice on a realistic basis.

LeiKA: an optional German general practice teaching project for first-semester medical students: who is taking part and why? A cross-sectional study

OBJECTIVES

This study investigates students' adoption of LeiKA, a new extracurricular longitudinal general practice (GP) teaching project. LeiKA aims to attract a broad range of students, not only those who are already planning to become GPs. This study compares participants' and non-participants' characteristics, career preferences and job-related value orientations to assess the programme's initial potential to increase the number of students subsequently entering GP careers. Additionally, students' motives for taking part in the programme were explored.

DESIGN

We analysed administrative data and data from a cross-sectional questionnaire survey for the first three cohorts. LeiKA participants were compared with non-participants regarding baseline characteristics, career intentions and attitudes associated with GP careers. There was also a qualitative analysis of the reasons for taking part.

SETTING

Faculty of Medicine, University of Leipzig, Germany.

PARTICIPANTS

First-semester medical students in the years 2016-2018.

RESULTS

In the first 3 years, 86 of 90 LeiKA slots were taken, 9.0% (n=86/960) of those eligible to apply. LeiKA participants were a mean of 0.6 years older (LeiKA: 21.5 vs whole cohort: 20.9 years, p<0.001) and slightly more interested in long-term doctor-patient relationships (3.6 vs 3.3, scale from 1 'unimportant' to 5 'very important', p=0.018), but did not differ regarding other characteristics and attitudes. Although more participants definitely favoured a GP career (13.1% vs 4.9%, p=0.001), it was a possible option for most students in both groups (78.6% vs 74.0%). Early acquisition of skills and patient contact were the main motives for taking part, stated by 60.7% and 41.7% of the participants, respectively.

CONCLUSIONS

The extracurricular programme was taken up by a broad range of students, indicating its potential to attract more students to become GPs. The reasons for taking part that we identified may guide the planning of other similar projects.

Willingness, concerns, incentives and acceptable remuneration regarding an involvement in teaching undergraduates - a cross-sectional questionnaire survey among German GPs

BACKGROUND

Worldwide, many undergraduate general practice curricula include community-based courses at general practitioners' (GPs') offices. Usually the academic general practice departments collaborate with networks of affiliated teaching practices. To successfully master the challenge of network development and extension, more information is needed about GPs' willingness to be involved in different teaching formats, important influencing factors, incentives, barriers, and the need for financial compensation.

METHODS

In this cross-sectional study a questionnaire survey was conducted among all GPs working in Leipzig and environs (German postal code area 04). In addition to descriptive statistics, group comparisons and logistic regression were performed to reveal differences between GPs with and without an interest in teaching.

RESULTS

Response rate was 45.3% with 339 analyzable questionnaires. The average age was 52.0 years and 58.4% were women. Sixty-two participants stated that they were already involved in teaching undergraduates. Altogether 60.1% of all GPs and 53.5% among those who didn't teach yet were basically interested in being involved in undergraduate education. The interested GPs could imagine devoting on average 6.9 h per month to teaching activities. GPs interested in teaching were on average younger, were more actively involved in continuing education and professional associations, and more frequently had pre-existing teaching experiences. The willingness to teach differed substantially among teaching formats. GPs were more willing to teach at their own practices rather than at university venues and they preferred skills-oriented content. Comprehensive organization on the part of the university including long-term scheduling and available teaching materials was rated as most important to increase the attractiveness of teaching. Time restraints and decreased productivity were rated as the most important barriers. Interested GPs appreciated financial compensation, particularly for teaching at university venues, and demanded amounts of money corresponding to German GPs' hourly income.

CONCLUSIONS

The GPs' interest in undergraduate teaching is generally high indicating a substantial pool of potential preceptors. Recruitment strategies should consider the collaboration with institutions involved in residency and continuing education as well as with professional associations. Comprehensive organization by the responsible department should be promoted and time restraints and decreased productivity should be overtly addressed and financially compensated.

The Investigation of Suspected Fracture-a Comparison of Ultrasound With Conventional Imaging

BACKGROUND

Ultrasound imaging can be used to diagnose fractures in patients with acute trauma. Its main advantages over conventional imaging are the absence of radiation exposure and its greater availability.

METHODS

A systematic search in electronic databases (Medline, Embase, Cochrane CENTRAL) was supplemented by a manual search on the Internet and in the reference lists of pertinent publications. The QUADAS-2 instrument was used to assess the quality of the individual studies retrieved. In the metaanalysis, the sensitivity and specificity of the individual studies were pooled.

RESULTS

The available information on the diagnostic accuracy of ultrasound in the detection of fractures compared with that of conventional imaging (x-ray, CT, MRI) in patients with acute non-life-threatening trauma is summarized. The database search yielded 2153 hits, among which there were 48 studies that were suitable for inclusion in this review. The pooled sensitivity and specificity were 0.91 (95% confidence interval [0.90; 0.92]) and 0.94 [0.93; 0.95], although the analyzed studies were markedly heterogeneous (I²: sensitivity 74%, specificity 81%). The sensitivity of ultrasound was higher for the detection of fractures of the humerus, the forearm, the ankle, and the long bones in general, as well as fractures in children, and lower for fractures of the short bones of the hands and feet, and in adults.

CONCLUSION

Strong evidence supports the use of ultrasound imaging for certain indications in the detection of fractures.

Results of 115 Rubis II reverse thumb carpometacarpal joint prostheses with a mean follow-up of 10 years

The aim of this study was to assess the clinical and radiological results of the Rubis II thumb carpometacarpal joint reverse prosthesis, at a mean follow-up of 10 years. Between 1997 and 2008, 253 prostheses were implanted in 199 patients; 115 were reviewed. The survival after a mean of 10 years was 89%. At the last follow-up, 70% of prostheses were painless; the others reported moderate or intermittent pain. The satisfaction rate was 98%. The mean opposition was 9 on the Kapandji scale; the mean QuickDASH score was 30. Wrist, key and tip pinch strengths were comparable with the non-operated side. Of the 115 implants, one was radiologically loose (1%) and 15 had suffered dislocations (13%), 12 of which were caused by an injury. Eleven thumbs had revision surgery. This study confirms that the good clinical results of the Rubis II prosthesis are maintained in the medium and long term, and represents a useful alternative to trapeziectomy for selected patients.

Choosing to become a general practitioner - What attracts and what deters? An analysis of German medical graduates' motives

BACKGROUND

To be able to counter the increasing shortage of general practitioners (GPs) in many countries, it is crucial to remain up-to-date with the decisive reasons why young physicians choose or reject a career in this field.

MATERIALS AND METHODS

Qualitative content analysis was performed using data from a cross-sectional survey among German medical graduates (n = 659, response rate = 64.2%). Subsequently, descriptive statistics was calculated.

RESULTS

The most frequent motives to have opted for a GP career were (n = 74/81): Desire for variety and change (62.2%), interest in a long-term bio-psycho-social treatment of patients (52.7%), desire for independence and self-determination (44.6%), positively perceived work-life balance (27.0%), interest in contents of the field (12.2%), and reluctance to work in a hospital (12.2%). The most frequent motives to have dismissed the seriously considered idea of becoming a GP were (n = 207/578): Reluctance to establish a practice or perceived associated risks and impairments (33.8%), stronger preference for another field (19.3%), perception of workload being too heavy or an unfavorable work-life balance (15.0%), perception of too low or inadequate earning opportunities (14.0%), perception of the GP as a distributor station with limited diagnostic and therapeutic facilities (11.6%), perception of too limited specialization or limited options for further sub-specialization (10.6%), rejection of (psycho-) social aspects and demands in general practice (9.7%), and perceived monotony (9.7%).

CONCLUSION

While some motives appear to be hard to influence, others reveal starting points to counter the GP shortage, in particular, with regard to working conditions, the further academic establishment, and the external presentation of the specialty.

Who wants to become a general practitioner? Student and curriculum factors associated with choosing a GP career--a multivariable analysis with particular consideration of practice-orientated GP courses

OBJECTIVE

Because of the increasing shortage of general practitioners (GPs) in many countries, this study aimed to explore factors related to GP career choice in recent medical graduates. Particular focus was placed on the impact of specific practice-orientated GP courses at different stages of the medical undergraduate curriculum.

DESIGN

Observational study. Multivariable binary logistic regression was used to reveal independent associations with career choice.

SETTING

Leipzig Medical School, Germany.

SUBJECTS

659 graduates (response rate = 64.2%).

MAIN OUTCOME MEASURE

Choice of general practice as a career.

RESULTS

Six student-associated variables were found to be independently related to choice of general practice as a career: age, having family or friends in general practice, consideration of a GP career at matriculation, preference for subsequent work in a rural or small-town area, valuing the ability to see a broad spectrum of patients, and valuing long-term doctor-patient relationships. Regarding the curriculum, after adjustment independent associations were found with a specific pre-clinical GP elective (OR = 2.6, 95% CI 1.3-5.3), a four-week GP clerkship during the clinical study section (OR = 2.6, 95% CI 1.3-5.0), and a four-month GP clinical rotation during the final year (OR = 10.7, 95% CI 4.3-26.7). It was also found that the work-related values of the female participants were more compatible with those of physicians who opt for a GP career than was the case for their male colleagues.

CONCLUSION

These results support the suggestion that a practice-orientated GP curriculum in both the earlier and later stages of undergraduate medical education raises medical schools' output of future GPs. The findings are of interest for medical schools (curriculum design, admission criteria), policy-makers, and GPs involved in undergraduate medical education. More research is needed on the effectiveness of specific educational interventions in promoting interest in general practice as a career.

[Recruitment for general practice - relationship between practice-based curriculum and career choice]

BACKGROUND

Demographic change and recruitment problems in general practice are increasingly threatening an adequate primary care workforce in many countries. Medical schools play an important role in attracting young physicians to this field. The influence of the general practice curriculum on the career choice of graduates has not yet been sufficiently investigated.

METHODS

The present study combines continuously collected data of medical students concerning the participation in miscellaneous general practice courses with data of a later graduate survey.

RESULTS

Response rate was 64.2%. Although only 4.7% of the participants preferred a career in general practice at study entry, this specialty was, at 12.3%, the second most frequent career choice. Among the future general practitioners, only 18.5% had initially planned this career. The future general practitioners took part significantly more frequently in all facultative general practice courses. They reported more frequently to have met role models in general practice and to have gained experience in rural areas. Future general practitioners would more often prefer to work in rural areas in the future.

CONCLUSIONS

Overall, the present results indicate that a broad and practice-oriented general practice curriculum has the potential to attract medical students to the specialty.

Primary care research - trade-off between representativeness and response rate of GP teachers for undergraduates

PRINCIPLES

Low response rates are common in primary care research. Our study examines the representativeness of respondents in a survey among general practitioners (GPs). One special aim was to evaluate the representativeness of the subgroup of GP teachers for undergraduates (GPTUs) and to investigate the option of a panel of GPTUs.

METHODS

The representativeness of the respondents was assessed by the use of pooled public data to compare the respondents and all GPs in the German federal state of Saxony on the basis of socio-demographic and subject-specific characteristics. The representativeness of the GPTUs was examined in the same way. For the analysis, two-sided t-tests and Chi2 tests were used.

RESULTS

The total response rate was low (32.87%). The respondents were not a representative sample; in particular, they were more highly qualified than the mean. However, the response rate among the special group of university-associated GP teachers for undergraduates was significantly higher than among other general practitioners. Because of this, the creation of a panel of these GPTUs for further primary care research was investigated. Unfortunately, analysis of this group showed that GPTUs were not a representative sample as they tended to be younger and more highly qualified.

CONCLUSIONS

In general it is possible to create a panel of GPTUs to obtain higher response rates, but investigation of the panel's representativeness is definitely required. If the panel is not representative another option is the creation of a stratified sample according to the target population.

Insomnia: therapeutic approach

Insomnia is a common complaint. Transient and short-term insomnias usually result from stress or the use of certain pharmaceuticals or drugs and may be managed by reduced caffeine use, behavioral means, and/or pharmacologic treatment. Long-term insomnia is often a symptom of a medical or psychiatric condition or a primary sleep disorder. A diagnostic workup is expected; treatment should focus on the causative condition, as well as addressing the sleep problem itself. Established medications for the symptomatic treatment of insomnia include benzodiazepines, zolpidem, zaleplon, and certain antidepressant or occasionally antihistaminic drugs.

Delirious mania in the elderly

Delirious mania is a clinical syndrome in which the signs and symptoms of delirium manifest themselves in the context of a manic episode. Though there have been numerous descriptions and case reports of this syndrome, all have described mania as the presenting feature, with signs of delirium developing subsequently, and none of the vignettes have involved elderly patients. We report two cases of elderly individuals with mania who initially presented as in a delirium. Both of them experienced clear manic episodes, which were confirmed by their psychiatric histories and clinical responses to mood stabilizers. Mania needs to be in the differential diagnosis of elderly people presenting with confusion, disorientation, and perceptual changes, particularly in those with a history of bipolar disorder.

Hair loss in psychopharmacology

Medication-induced alopecia is an occasional side effect of many psychopharmaceuticals. Most of the mood stabilizer and antidepressant drugs can lead to this condition. Some antipsychotic and antianxiety agents induce alopecia. Hair loss is also related to hypothyroidism, which can be induced by lithium and other agents. Alopecia might not be reported by some people, but physicians should be aware of this potential problem which may contribute to noncompliance. Lithium causes hair loss in 12-19% of long-term users. Valproic acid and/ or divalproex precipitates alopecia in up to 12% of patients in a dose-dependent relationship. Incidences up to 28% are observed with high valproate concentration exposures. These pharmaceuticals also can change hair color and structure. The occurrence of carbamazepine-induced alopecia is at or below 6%. Hair loss is less common with other mood stabilizers. Tricyclic antidepressants, maprotilene, trazodone, and virtually all the new generation of antidepressants may on rare occasions lead to alopecia. The same applies to haloperidol, olanzepine, risperidone, clonazepam, and buspirone, but not to other neuroleptics, benzodiazepines, or barbiturates, selected antihistamines, and antiparkinsonians. Discontinuation of the medication or dose reduction almost always leads to complete hair regrowth. The therapeutic value of mineral supplements remains unclear.

Psychiatric aspects of parathyroid disease

Parathyroid diseases can present with psychiatric symptoms and can be recognized through determinations of serum electrolytes, especially the calcium level. Psychiatric evaluations should include a serum calcium concentration test, which is also essential in reassessment of patients poorly responsive to mental illness treatment. A magnesium and a phosphate assay may also be diagnostically helpful. Abnormality of divalent cation levels may provide evidence for consideration of, or ruling out, parathyroid disorders. Determinations of parathyroid hormone are performed if clinically indicated, and if abnormal divalent cation quantifications are confirmed. If parathyroid disease is identified, corrective endocrine therapies may diminish or even cure psychiatric aspects of parathyroid pathology. Failure to recognize a parathyroid disorder leaves an endocrine-induced mental dysfunction without proper treatment.

Prompt differentiation of Addison's disease from anorexia nervosa during weight loss and vomiting

An 18-year-old white woman had nausea, vomiting, weight loss, and a diagnosis of anorexia nervosa. Copper-colored skin was noted on physical examination, and serum chemistry values were normal. Subsequent fever, disorientation, and confusion led to the discovery of Addison's disease, which responded well to corticosteroid replacement therapy. Addisonian and anorexic patients exhibit clinical similarities, including nausea, vomiting, weight loss, abdominal pain, cold intolerance, hypothermia, and orthostasis. Other commonalities include prolongation of electrocardiographic PR and QT intervals and generalized slowing on electroencephalogram. Important differences include a brown color to the skin in Addison's disease instead of a yellowish color in anorexia. Addisonian patients also display hypocortisolism, hypoglycemia, and hyperkalemia, in contrast to the hypercortisolism, hyperglycemia, and hypokalemia seen in anorexia.

Divalproex: a possible treatment alternative for demented, elderly aggressive patients

Elderly, demented people often exhibit behavioral dyscontrol. Divalproex appears to be safe and effective in the management of this presentation. Twelve cases treated with divalproex all responded with improved emotional control. Patients became less verbally and physically disruptive and much more socially appropriate. Divalproex was well tolerated in this population with none of the subjects experiencing significant medicinal side effects. This uncontrolled report suggests that divalproex should be considered as a pharmacotherapy for aggressivity in cognitively impaired, elderly people.

How to treat coexistent mental illness and substance abuse

Integration of mental illness and substance abuse treatments is important for patients with "dual diagnosis", the coexistence of an emotional ailment and a chemical dependency. Such comorbidity is usually associated with a poor prognosis. Both disorders require appropriate therapy so that remission of psychiatric symptoms and maintenance of sobriety become reachable goals for these individuals. A joint therapeutic approach improves outcome, functional expectation, and community adjustment.

ECG intervals in acute bipolar and schizophrenic relapse

Psychosis in general and acute relapse of bipolar illness, in particular, are associated with elevated catecholamine excretion, cardiovascular changes, and changes in intracellular calcium concentration. In an effort to determine if these changes result in observable ECG abnormalities, we retrospectively examined ECG parameters of acutely disturbed bipolar and schizophrenic patients. There were no discrete patterns of abnormalities, and no significant differences were observed between the two patient groups. Most ECG changes in acutely hospitalized bipolar and schizophrenic patients appear to be benign.

A two-year follow-up on the effects of a smoking ban in an inpatient psychiatric service

The effects of prohibiting cigarette smoking on the behavior of patients on a 25-bed psychiatric inpatient unit were assessed immediately after implementation of a smoking ban and two years later. No major behavioral disruptions were observed after the ban. The number of calls for security assistance, physical assaults, instances of leather restraints and of seclusions, and discharges against medical advice did not increase significantly immediately after the restriction on smoking or two years later. Significantly more verbal assaults and prescribing of p.r.n. medications for anxiety occurred immediately after the ban but not two years later.

Unsuspected subdural hematoma as a differential diagnosis in elderly patients

Subdural hematomas are among the most common forms of intracranial hemorrhage encountered in clinical practice and are a surgically remediable cause of dementia. When the symptom presentation is subtle or diffuse, a subdural hematoma can be overlooked. This is especially true among elderly people who may exhibit unrelated, preexisting dementia or delirium. Particularly confusing is that such declines in intellectual capacity can also result from subdural hematoma. It is therefore essential that a thorough physical and neurologic assessment be done on all patients with cognitive deficiencies. This always includes brain imaging. Early recognition of a subdural hematoma is important, given its treatability and potential reversibility. We describe an elderly woman with new-onset cognitive deficit and gait dyspraxia. There was no evidence of trauma. Physical examination was otherwise unremarkable. Initially, she refused evaluation, but once a subdural hematoma was identified by a tomographic scan, a satisfactory outcome followed surgical intervention.

Obsessive-compulsive disorder. How to free patients from intrusive thoughts and rituals

The antidepressants clomipramine hydrochloride (Anafranil), fluoxetine hydrochloride (Prozac), and sertraline hydrochloride (Zoloft) are the main choices for pharmacologic treatment of obsessive-compulsive disorder. Often, drug doses for obsessive-compulsive disorder are higher than for depression, and improvement occurs more slowly and is often only partial. Behavior therapy involving exposure to feared objects or situations and prevention of ritualistic behavior complements pharmacologic treatment. Referral to a behavioral therapist may be necessary to achieve recovery.

Wilson's disease. Psychiatric manifestations may be the clinical presentation

It is important to consider Wilson's disease in patients with psychiatric signs and symptoms who also have abnormal liver function test results or neurologic findings, or both. Thorough evaluation of emotionally disturbed persons, including complete history taking, careful physical examination, and appropriate laboratory profile, generally rules out or arouses suspicion of Wilson's disease during routine screening. Laboratory abnormalities necessitate repeated studies and additional family and personal history taking with emphasis on possible Wilson's disease. Further workup may then be indicated. Prompt recognition and vigorous, consistent treatment can minimize symptoms and tissue damage. Identifying a case of Wilson's disease and seeing clinical aspects improve with appropriate therapy is gratifying.

Procedural complications of electroconvulsive therapy: assessment and recommendations

We surveyed procedural techniques in 804 routine clinical sessions of electroconvulsive therapy (ECT) over 4 2/3 years. No significant problems occurred. Side effects as agitation, physical complications such as urinary stasis, and protocol deviations such as failure to use the bite block were occasionally documented. Mechanical difficulties such as trouble gaining intravenous access and medicinal problems such as inappropriate dosing were rare. Our assessment resulted in a more precise method of diminishing the risks of ECT. For example, the chin is held manually, closing the mouth during delivery of the stimulus, to obviate oral trauma. Similarly, electrode contact is always verified visually and with the ECT machine "self-test" just before each treatment. Both cuff and electroencephalographic means are used to determine seizure timing. ECT is safe; a carefully applied protocol should make it safer.

Pharmacologic treatment strategies for the depressed, poorly responsive patient

Treatment-resistant depression implies a failure of response to an ample dose of antidepressant medicine, prescribed over a sufficient length of time. Assessing drug levels in the blood is often helpful in confirming the adequacy of antidepressant dosages. Augmentation of the pharmaceutical activity can be achieved by coadministration of lithium, triiodothyronine, and/or stimulants. Neuroleptics are also prescribed with the antidepressant when psychotic features accompany depression. Such enhancements to drug efficacy are usually an advantage over beginning a new medication because of shorter response time. When a decision is made to change the antidepressant, a structurally different option is more likely to induce a remission than a medication of similar configuration. Electroconvulsive therapy is the most powerful treatment choice for depressed patients, especially when suicidal or psychotic features are present.

Preventing suicide in older people

Prompt recognition of suicidal intent can prevent suicide in the elderly. Some psychiatric disorders, such as depression, psychoses and organic brain syndromes, can predispose these persons to suicide, as can medical disorders that result in pain, disability or dysfunction. Other factors that increase the risk for suicide include chemical dependency and changing life events. Anti-depressant medications with a low anticholinergic and sedative profile are preferred because of age-related physiologic changes. Electroconvulsive therapy is reserved for serious cases.

Violent patients. Are you prepared to deal with them?

The medical community is becoming increasingly concerned about violent patients in healthcare settings. Healthcare professionals should be trained to deal with aggressive patients, and they should have access to a room free of dangerous objects for evaluation and examination. Having security personnel stand by may be appropriate in some cases. Verbal intervention is the key to dealing with violent patients. The safest and most effective pharmacologic intervention is use of benzodiazepines, either alone or in conjunction with antipsychotic agents when indicated. Seclusion or restraint may be needed for some violent patients; in such situations, close patient monitoring and explicit documentation are essential. Physicians can be held liable for injuries patients sustain while being restrained, so staff members should receive instruction in safe physical intervention techniques.

Bupropion: overview and prescribing guidelines in depression

Bupropion is a new antidepressant medicine that is chemically distinct from previous agents. Clinical studies have shown it to be as effective as the standard antidepressant drugs currently used in the treatment of major depression. It is useful in patients resistant to other agents as well as in patients with atypical depression. Bupropion is 10 to 100 times less likely to induce cardiac conduction problems than the tricyclic drugs, and orthostatic hypotension is rare. Minimal anticholinergic effects account for its being generally well tolerated. The most common side effect is dry mouth. An epileptogenic potential is prominently reported. Because it may lower the convulsive threshold, bupropion is not recommended for individuals who may be predisposed to seizures. In people without an increased ictal risk factor, and when dosage is maintained at 450 mg/day or less in a divided schedule, the seizure rate is comparable to that of other antidepressant drugs.

Dementia: what to do

Dementia is a syndrome of acquired intellectual deterioration that interferes with personal or social functioning. Diagnosis requires historical information from the family and the mental status evaluation of orientation, recent memory, comprehension, calculation, and abstraction. Most dementias create permanent, even progressive cognitive deterioration, yet there are some presentations for which remission exists. Common reversible conditions include depression, drug toxicity, normal-pressure hydrocephalus, hypothyroidism, subdural hematoma, and neoplasm. Screening laboratory studies consist of urinalysis, chemistry profile, blood count, thyroid survey, vitamin B12 and folate measurements, serology, chest roentgenogram, computerized tomographic scan of the head, electroencephalogram, and electrocardiogram. Treatment focuses on potential reversibility, psychosocial issues, restoring deficits, and specific symptoms.

Dementia in the elderly

When are confusion and forgetfulness transient signs of normal aging, when are they signs of depression or a medical illness, and when are they signs of dementia? The authors describe clinical features and diagnostic studies that help establish the presence of dementia and discuss ways of coping with both remediable and less treatable types.
