Key aspects of psychosocial needs in palliative care - a qualitative analysis within the setting of a palliative care unit in comparison with specialised palliative home care.

BACKGROUND: The number of palliative care patients with complex needs is increasing in developed countries. In addition to physical aspects and symptom control, psychosocial aspects are of great importance for palliative care patients. The aim of this study was to understand which psychosocial aspects are important to patients, relatives and health professionals within the setting of a palliative care unit in comparison with specialised palliative home-care (SPHC). METHODS: We used a qualitative design based on semistructured interviews, which were coded via qualitative content analysis. The study took place in the state of Hesse, Germany, and data collection was conducted in 2017 (interviews from the ELSAH study, which was conducted in a SPHC) and 2018 (supplementary interviews conducted in a palliative care unit). The results from both settings were compared. RESULTS: In the palliative care unit, 10 health professionals, 11 patients and 8 relatives were interviewed. In the outpatient setting, we interviewed 30 health professionals, 14 patients and 14 relatives. We identified four key psychosocial issues related to palliative care that were relevant in both the inpatient and outpatient settings: care planning, patient-centred care, a protected environment with feelings of safety, and psychological well-being. In addition, immediate availability of medical staff, greater relief of the relatives and better accessibility of psychological care were more important in the inpatient setting than in the specialised palliative home care setting. CONCLUSIONS: Knowledge and application of the identified key issues may improve patient-centred palliative care. Accessibility of psychological care and immediate availability of medical staff may be important factors for enhancing psychological well-being in the inpatient palliative care setting. Consideration of the identified key issues may help to develop more collaborative transitions between the palliative care unit and the SPHC and may help to provide palliative care patients and their families with care that is appropriate and feasible for them. TRIAL REGISTRATION: The underlying comparative study of the outpatient setting of specialised palliative home-care (ELSAH) was registered within the German Clinical Trials Register DRKS-ID: DRKS00012421, ( https://drks.de/search/de/trial/DRKS00012421 ) on 19th May 2017.

Care practices of specialized outpatient pediatric palliative care teams in collaboration with parents: Results of participatory observations.

BACKGROUND: Collaboration between parents and professional care providers is an essential part of pediatric palliative care. As children are embedded in family systems and many of the patients are not able to communicate verbally, their parents are the primary interaction partners for palliative care providers. International standards for pediatric palliative care in Europe state that parents should be supported, acknowledged as the primary carers and involved as partners in all care and decisions. AIM: To find out through which care practices pediatric palliative care teams shape collaboration with parents in everyday care. DESIGN: Ethnographic method of participatory observations. Field notes were analyzed using thematic analysis. SETTING/PARTICIPANTS: Researchers accompanied three pediatric palliative care teams on home visits to eight different families caring for a child with life-limiting conditions. RESULTS: Care practices of palliative care teams were characterized by familiarity, a resource-oriented attitude, empowerment of parents, shared decision-making and support for parents. Palliative care teams not only provided palliative medical treatment for the children, but also developed a trusting care partnership with parents. The teams employed a sensitive and multifaceted communication style in their collaboration with parents. CONCLUSIONS: Care practices in pediatric palliative care require time, communication skills, and a high level of psychosocial competence, to develop a trusting, collaborative relationship with parents. This should be taken into consideration when establishing pediatric palliative care structures, preparing guidelines, training staff, and deciding upon appropriate remuneration.

Inductive foraging: patients taking the lead in diagnosis, a mixed-methods study.

BACKGROUND: Patient involvement in treatment decisions is widely accepted. Making a diagnosis, however, is still seen as a technical task mainly driven by physicians. Patients in this respect are perceived as passive providers of data. But, recent patient-centred concepts highlight the value of an active patient involvement in diagnosis. OBJECTIVE: We aim to reach a deeper understanding of how patients themselves contribute to the diagnostic process. METHODS: This is an observational study of patient consultations with their General Practitioner (GP) in 12 German practices. We performed a mixed-method qualitative and quantitative analysis of 134 primary care consultations. RESULTS: At the beginning of most consultations lies a phase where patients were invited to freely unfold their reason for encounter: This was named "inductive foraging" (IF). While patients actively present their complaints, GPs mainly listen and follow the presentation. This episode was found with every GP participating in this study. Ninety-one percent of consultations with diagnostic episodes were opened by IF. IF had a major contribution to the number of cues (diagnostic information) yielded in the diagnostic process. We illustrate a variety of tactics GPs make use of to invite, support, and terminate their patients in IF. CONCLUSION: IF was found to be a highly relevant strategy in the diagnostic process. Patient involvement through IF offered a major contribution of diagnostic cues. We hypothesize that a patient-centred approach improves diagnosis.

Making a diagnosis is a central part in medicine. Before advising treatments, physicians need to understand patients' complaints and ideally the reason for their symptoms. Generating an accurate diagnosis is often attributed to clinicians asking many specific questions and performing an array of tests. The patients' task in turn is passively answering "yes" or "no," or donating blood. In this study, we shed a different light on the phenomenon of diagnosis. We observed and recorded 295 primary care consultations. After each consultation, GPs were asked to reflect on their diagnostic thinking during the encounter. At the beginning of consultations, we witnessed a phase where patients were invited to freely report their complains and unfold their reason for encounter. Here, physicians mainly listened to their patients and motivated for further elaboration. We termed this phase "inductive foraging." GPs received the majority of diagnostic information (cues) during this phase. We therefore belief that an active patient involvement may improve diagnosis.

State-wide implementation of patient-reported outcome measures (PROMs) in specialized outpatient palliative care teams (ELSAH): A mixed-methods evaluation and implications for their sustainable use.

BACKGROUND: Such patient-reported outcome measures (PROMs) and patient-centered outcome measures as the Integrated Palliative Care Outcome Scale (IPOS), Phase of Illness, and IPOS Views on Care (IPOS VoC), facilitate patient-centered care and help improve quality. To ensure sustainability, implementation and usage should be adapted according to setting. When settings involve several distinct teams that differ in terms of views and working practices, it is more difficult to integrate outcome measures into daily care. The ELSAH study aimed to learn how health professionals working in specialized outpatient palliative care (SOPC) viewed the use of these outcome measures in daily care, and what they express is needed for successful sustainable, state-wide application. METHODS: We used a parallel mixed-methods design involving three focus groups (n = 14) and an online-survey based on normalization process theory (n = 76). Most participants were nurses and physicians from 19 SOPC-teams in Hesse, Germany. We used a triangulation protocol including convergence coding matrices to triangulate findings. RESULTS: The majority of health professionals were able to integrate the outcome measures into their working lives and said that it had become a normal part of their day-to-day work. To ensure their sustainable integration into daily care, the motivation and concerns of health professionals should be taken into consideration. Health professionals must clearly recognize how the measures help improve daily care and quality evaluation. CONCLUSIONS: To implement the outcome measures in a number of teams, it will be necessary to take individual team characteristics into account, because they influence motivation and concerncs. Further, it will be necessary to offer opportunities for them to engage in peer support and share information with other teams. The sustainable use of outcome measures in SOPC will require continuous support within each team as well as across teams. When several distinct teams are working in the same setting, a cross-team coordination unit can help to coordinate their work efficiently.

Integrating patient- and caregiver-reported outcome measures into the daily care routines of specialised outpatient palliative care: a qualitative study (ELSAH) on feasibility, acceptability and appropriateness.

BACKGROUND: The use of patient-reported outcome measures (PROM) and caregiver-reported outcome measures can raise the patient centeredness of treatment and improve the quality of palliative care. Nevertheless, the everyday implementation of self-report in patients and caregivers is complex, and should be adapted for use in specific settings. We aimed to implement a set of outcome measures that included patient and caregiver self- and proxy-reported outcome measures in specialised outpatient palliative care (SOPC). In this study, we explore how the Integrated Palliative Outcome Scale (IPOS), IPOS Views on Care (IPOS VoC) and the Short-form Zarit Caregiver Burden Interview (ZBI-7) can be feasibly, acceptably and appropriately implemented in the daily care routines of SOPC. METHODS: Five SOPC teams were trained, and used the outcome measures in daily practice. Team members were mainly nurses and physicians. To investigate their feedback, we used a multi-method qualitative design consisting of focus groups with SOPC-team members (n = 14), field notes of meetings and conversations with the SOPC teams. In an iterative process, we analysed the findings using qualitative content analysis and refined use of the outcome measures. RESULTS: We found that integrating patient and caregiver outcome measures into daily care routines in SOPC is feasible. To improve feasibility, acceptability and appropriateness, the resulting burden on patients and relatives should be kept to a minimum, the usefulness of the measures must be understood, they should be used considerately, and administration must be manageable. We removed ZBI-7 from the set of measures as a result of feedback on its content and wording. CONCLUSIONS: SOPC-team members have reservations about the implementation of PROM in SOPC, but with appropriate adjustments, its application in daily care is feasible, accepted and perceived as appropriate. Previous to use, SOPC-team members should be trained in how to apply the measures, in the design of manageable processes that include integration into electronic documentation systems, and in ongoing evaluation and support. They should also be taught how useful the measures can be. TRIAL REGISTRATION: May 19th, 2017, German Clinical Trials Register DRKS-ID: DRKS00012421 .

How can we ensure the success of specialised palliative home-care? A qualitative study (ELSAH) identifying key issues from the perspective of patients, relatives and health professionals.

BACKGROUND: Specialised palliative home-care supports patients with life-limiting diseases in their familiar surroundings. The number of palliative care teams and patients being cared for is increasing worldwide. To assess and improve quality, it is needed to understand, how specialised palliative home-care can be provided successfully. For this purpose we examined the views of all involved stakeholders. AIM: To identify the issues that patients, their relatives and involved health professionals view as important in ensuring the success of specialised palliative home-care. DESIGN: We used a qualitative design based on participant observations, interviews and focus groups following the principles of a Grounded Theory approach. SETTING/PARTICIPANTS: All specialised palliative home-care teams (n = 22) caring for adults in Hesse, Germany, participated. We conducted participant observations (n = 5), and interviewed patients (n = 14), relatives (n = 14) and health professionals working in or collaborating with specialised palliative home-care (n = 30). We also conducted focus groups (n = 4) with health professionals including a member check. RESULTS: Successful specialised palliative home-care needs to treat complex symptoms, and provide comprehensive care including organisation of care, involving relatives and addressing issues of death and dying. Sense of security for patients and relatives is key to enable care at home. Care delivery preferences include a focus on the quality of relationships, respect for individuality and the facilitation of self-determination. CONCLUSIONS: Consideration of the identified key issues can help to ensure successful specialised palliative home-care. Knowledge of these should also be considered when researching and assessing quality of care. TRIAL REGISTRATION: German Clinical Trials Register DRKS-ID: DRKS00012421; http://www.germanctr.de.

Coughing children in family practice and primary care: a systematic review of prevalence, aetiology and prognosis.

BACKGROUND: For evidence-based decision making, primary care physicians need to have specific and reliable information on the pre-test probabilities of underlying diseases and a symptom's course. We performed a systematic review of symptom-evaluating studies in primary care, following three research questions: (1) What is the prevalence of the symptom cough in children consulting primary care physicians? (2) What are the underlying aetiologies of cough and the respective frequencies? (3) What is the prognosis of children with cough? METHODS: Following a pre-defined algorithm and independent double reviewer ratings we searched MEDLINE and EMBASE. All quantitative original research articles in English, French or German were included if they focused on unselected study populations of children consulting a primary care physician for cough. We used the random effects model for meta-analysis in subgroups, if justifiable in terms of heterogeneity. RESULTS: We identified 14 eligible studies on prevalence, five on aetiology and one on prognosis. Prevalence estimates varied between 4.7 and 23.3% of all reasons for an encounter, or up to estimates of 60% when related to patients or consultations. Cough in children is more frequent than in adults, with lowest prevalences in adolescents and in summer. Acute cough is mostly caused by upper respiratory tract infections (62.4%) and bronchitis (33.3%); subacute or chronic cough by recurrent respiratory tract infection (27.7%), asthma (up to 50.4% in cough persisting more than 3 weeks), and pertussis (37.2%). Potentially serious diseases like croup, pneumonia or tuberculosis are scarce. In children with subacute and chronic cough the total duration of cough ranged from 24 to 192 days. About 62.3% of children suffering from prolonged cough are still coughing two months after the beginning of symptoms. CONCLUSION: Cough is one of the most frequent reasons for an encounter in primary care. Our findings fit in with current guideline recommendations supporting a thoughtful wait-and-see approach in acute cough and a special awareness in chronic cough of the possibility of asthma and pertussis. Further evidence of aetiological pre-test probabilities is needed to assess the diagnostic gain based on patient history and clinical signs for differential diagnoses of cough in children.

Prevalence, aetiologies and prognosis of the symptom cough in primary care: a systematic review and meta-analysis.

BACKGROUND: Cough is a relevant reason for encounter in primary care. For evidence-based decision making, general practitioners need setting-specific knowledge about prevalences, pre-test probabilities, and prognosis. Accordingly, we performed a systematic review of symptom-evaluating studies evaluating cough as reason for encounter in primary care. METHODS: We conducted a search in MEDLINE and EMBASE. Eligibility criteria and methodological quality were assessed independently by two reviewers. We extracted data on prevalence, aetiologies and prognosis, and estimated the variation across studies. If justifiable in terms of heterogeneity, we performed a meta-analysis. RESULTS: We identified 21 eligible studies on prevalence, 12 on aetiology, and four on prognosis. Prevalence/incidence estimates were 3.8-4.2%/12.5% (Western primary care) and 10.3-13.8%/6.3-6.5% in Africa, Asia and South America. In Western countries the underlying diagnoses for acute cough or cough of all durations were respiratory tract infections (73-91.9%), influenza (6-15.2%), asthma (3.2-15%), laryngitis/tracheitis (3.6-9%), pneumonia (4.0-4.2%), COPD (0.5-3.3%), heart failure (0.3%), and suspected malignancy (0.2-1.8%). Median time for recovery was 9 to 11 days. Complete recovery was reported by 40.2- 67% of patients after two weeks, and by 79% after four weeks. About 21.1-35% of patients re-consulted; 0-1.3% of acute cough patients were hospitalized, none died. Evidence is missing concerning subacute and chronic cough. CONCLUSION: Prevalences and incidences of cough are high and show regional variation. Acute cough, mainly caused by respiratory tract infections, is usually self-limiting (supporting a "wait-and-see" strategy). We have no setting-specific evidence to support current guideline recommendations concerning subacute or chronic cough in Western primary care. Our study presents epidemiological data under non non-pandemic conditions. It will be interesting to compare these data to future research results of the post-pandemic era.

Global Health as "umbrella term" - a qualitative study among Global Health teachers in German medical education.

BACKGROUND: The increasing impact of globalisation on healthcare demands new knowledge, skills and attitudes from healthcare professionals. One consequence of this is the rise of Global Health (GH) programs in health education all over the world. In Germany no consensus exists on what GH is and how it should be taught. This study used a grounded theory approach. We conducted eleven in-depth interviews with GH teachers in German medical education to ask them about their views on Global Health and the approaches they took in teaching these topics. Data collection and Analysis informed each other and followed an inductive approach. RESULTS: Our research identified three major questions: (1) What is GH? (2) What belongs to GH? (3) How can GH be taught? A central finding of our study is the understanding of GH as an umbrella term. We show how this understanding helps clarify the relation between GH and Public Health, International Health and Tropical medicine. At the core of GH we see the supraterritorial determinants of health. Surrounding the core, we describe a wide variety of topics that are a facultative, but not necessarily a compulsory part GH. One of the key characteristics of GH within all its aspects is its multidisciplinary nature. Based on this understanding we present models about the content of GH, how it can be taught and how GH teaching improves and strengthens overall medical education. CONCLUSIONS: This is to our knowledge the first study that conducts in-depth interviews with GH teachers to explore the practical understanding of GH in medical education. While the generalisability of our results needs to be subject of further research, the models presented can help shape the future discourse around GH and its integration into medical education.

Prevalence, aetiologies and prognosis of the symptom dizziness in primary care - a systematic review.

BACKGROUND: Dizziness is a common reason for consulting a general practitioner and there is a broad range of possible underlying aetiologies. There are few evidence-based data about prevalence, aetiology and prognosis in primary care. We aimed to conduct a systematic review of symptom-evaluating studies on prevalence, aetiology or prognosis of dizziness in primary care. METHODS: We systematically searched MEDLINE and EMBASE. Two independent researchers screened titles and abstracts according to predefined criteria. We included all studies evaluating the symptoms 'dizziness' or 'vertigo' as a reason for consultation in primary care. We extracted data about study population and methodology and prevalence, aetiology and prognosis. Two raters independently judged study quality and risk of bias. We investigated the variation across studies using forest plots, I2 and prediction intervals. Since we anticipated a great amount of clinical and unexplained statistical heterogeneity, we provided qualitative syntheses instead of pooled estimates. RESULTS: We identified 31 studies (22 on prevalence, 14 on aetiology and 8 on prognosis). Consultation prevalence differs between 1,0 and 15,5%. The most common aetiologies are vestibular/peripheral (5,4-42,1%), benign peripheral positional vertigo (4,3-39,5%), vestibular neuritis (0,6-24,0%), Menière's disease (1,4-2,7%), cardiovascular disease (3,8-56,8%), neurological disease (1,4-11,4%), psychogenic (1,8-21,6%), no clear diagnosis (0,0-80,2%). While studies based on subjective patient assessment reported improvement rates from 37 to 77%, these findings could not be confirmed when applying instruments that measure symptom severity or quality of life. CONCLUSION: There is a broad variety of possible underlying diseases for the symptom dizziness. There exist only few methodologically sound studies concerning aetiology and prognosis of dizziness.

Study protocol: evaluation of specialized outpatient palliative care in the German state of Hesse (ELSAH study) - work package I: assessing the quality of care.

BACKGROUND: In Germany, patients suffering from life-limiting conditions are eligible for specialized outpatient palliative care (SOPC). Evaluation of the quality of this service lacks currently integration of patient-relevant outcomes. There is also no scientific consensus how to prove quality of care in the special context of SOPC adequately. Existing quality reports are primarily based on descriptive structural data which do not allow for estimation of process quality or result quality. The ELSAH study ('Evaluation of Specialized Outpatient Palliative Care in the German state of Hesse') aims to choose - or, if necessary, to adopt - to evaluate and to implement a suit of measures to assess, evaluate and monitor the quality of specialized, home-based palliative care. METHODS: All 22 SOPC teams providing their services in the state of Hesse, Germany, participate in the ELSAH study. The study is divided in two phases: a preparation phase and a main study phase. Based on the findings of the preparation phase we have chosen a preliminary set of instruments including the Integrated Palliative Outcome Scale, Views on Care, Zarit Burden Interview, Phase of Illness, Goal Attainment Scaling, Eastern Cooperative Oncology Group Performance Status, Consumer Quality Indices Palliative Care and Sense of Security in Care. During the main study phase, we will use a mixed-methods approach to evaluate the instruments' psychometric properties (reliability, validity, feasibility and practicability), to identify barriers, facilitators and limitations of their routine use and to explore how their use affects the care within the SOPC setting. DISCUSSION: At the end of this study, an outcome- and patient-centered, validated measurement approach should be provided, adapted for standardized evaluations in SOPC across patient groups, palliative care services and regions nationwide. The standardized application of instruments should allow for making valid statements and comparisons of health care quality in SOPC based on process- and outcome-evaluation rather than relying on structural data only. Moreover, the instruments might directly influence the care of patients in palliative situations. TRIAL REGISTRATION: German Clinical Trials Register (DRKS-ID: DRKS00012421 ).

Verification and feedback for medical students: an observational study during general practice rotations.

PURPOSE OF THE STUDY: A general practice and family medicine rotation is mandatory as part of undergraduate medical education. However, little is known about the student-teacher interaction in this specific setting of ambulatory teaching. In this study we analysed how frequently preceptors verified students' history taking and clinical examination skills and how often they gave feedback. The type of feedback given was also categorised. METHODS: From April to December 2012, 410 individual patient consultations were observed in 12 teaching practices associated with the Philipps University Marburg, Germany. Material was collected using structured field-note forms and videotaping. Descriptive data analysis was performed. Informed, written consent was provided by all participants. RESULTS: We analysed 410 consultations which lasted 14.8 min on average. In 130 (31.7%) consultations students took the patient's medical history; 124 (95.4%) of these were verified by the general practitioner (GP). Physical examination was performed by students in 202 (49.3%) of consultations; 169 (81.9%) of these were verified by the GP. Feedback occurred in 132 (32.2%) of the 410 patient consultations. Feedback was mostly non-specific and positive (68.9%), and occurred during consultation with the patient present. Specific, negative feedback also occurred relatively frequently (29.5%). Specific, positive and non-specific, negative responses were rarely given. CONCLUSIONS: GPs should give feedback more frequently and when doing so, focus on specific feedback. GPs should be further instructed in different feedback techniques.

The differential diagnosis of tiredness: a systematic review.

BACKGROUND: Tiredness is one of the most frequent complaints in primary care. Although often self-limiting and frequently associated with psychosocial stress, patients but also their physicians are often uncertain regarding a serious cause and appropriate diagnostic work-up. We conducted a systematic review and meta-analysis of studies reporting on differential diagnosis of fatigue in primary care. METHODS: MEDLINE, EMBASE and conference abstracts were searched for primary care based studies of patients presenting with tiredness. Twenty-six studies were included. We report on anaemia, malignancy, serious organic disease, depression and the chronic fatigue syndrome (CFS) as causes of tiredness as presenting complaint. RESULTS: We found considerable heterogeneity of estimates which was reduced by limiting our analysis to high quality studies. Prevalences were as follows-anaemia: 2.8 % (CI (confidence interval) 1.6-4.8 %); malignancy: 0.6 % (CI 0.3-1.3 %); serious somatic disease: 4.3 % (CI 2.7-6.7 %); depression 18.5 % (CI 16.2-21.0 %). Pooling was not appropriate for CFS. In studies with control groups of patients without the symptom of tiredness, prevalence of somatic disease was identical to those complaining of tiredness. Depression, however, was more frequent among those with tiredness. CONCLUSIONS: Serious somatic disease is rare in patients complaining of tiredness. Since prevalence is similar in patients without tiredness, the association may not be causal. Extensive investigations are only warranted in case of specific findings from the history or clinical examination. Instead, attention should focus on depression and psychosocial problems.

Diagnosing skin disease in primary care: a qualitative study of GPs' approaches.

BACKGROUND: Skin diseases are a common reason for consulting a GP. This regular occurrence happens despite most GPs' lack of knowledge and training in skin disease. OBJECTIVES: We aimed to explore different diagnostic approaches of GPs in patients presenting with a dermatological problem. In addition, we aimed to identify strategies used by GPs to handle diagnostic uncertainty in these patients. METHODS: We conducted interviews (20-40 minutes) with 14 GPs using a semi-structured guideline. Recalling encounters with patients with skin disease, GPs described their individual diagnostic strategies. Interviews were taped and transcribed verbatim. Qualitative analysis was conducted by two independent raters using a deductive-inductive approach. RESULTS: We identified several aspects of a complex decision-making process in GPs' diagnostic management of patients with dermatological problems. In the general diagnostic workup, GPs used a broad spectrum of different strategies such as spot diagnosis, stepwise refinement, pattern recognition trigger or test of treatment. GPs reduced diagnostic uncertainty through the identification of red flags, the application of the test of time, therapeutic trials and asking for further advice, including patient referral. CONCLUSIONS: GPs encounter a broad range of dermatological problems in their daily work using a variety of strategies in the workup of these patients. However, in a significant number of patients, there remains diagnostic uncertainty that is mainly reduced by specialist referral. Regular training in the diagnosis and treatment of common dermatological diseases should be offered to all GPs.

Studies of the symptom dyspnoea: a systematic review.

BACKGROUND: To deal with patients suffering from dyspnoea, it is crucial for general practitioners to know the prevalences of different diseases causing dyspnoea in the respective area and season, the likelihood of avoidable life-threatening conditions and of worsening or recovery from disease. AIM: Aim of our project was to conduct a systematic review of symptom-evaluating studies on the prevalence, aetiology, and prognosis of dyspnoea as presented to GPs in a primary care setting. METHODS: We did a systematic review of symptom-evaluating studies on dyspnoea in primary care. For this we included all studies investigating the complaint "dyspnoea" as a primary or secondary consulting reason in general practice. Apart from qualitative studies, all kind of study designs independent from type of data assessment, outcome measurement or study quality were included. Symptom-evaluating studies from other settings than primary care and studies which exclusively included children (age <18 years) were excluded from the review. Studies selecting patients prior to recruitment, e.g. because of an increased probability for a particular diagnosis, were also excluded. RESULTS: This systematic review identified 6 symptom evaluating studies on dyspnoea in the primary care setting. The prevalence of dyspnoea as reason for consultation ranges from 0.87 to 2.59 % in general practice. Among all dyspnoea patients 2.7 % (CI 2.2-3.3) suffer from pneumonia. Further specification of underlying aetiologies seems difficult due to the studies' heterogeneity showing a great variety of probabilities. CONCLUSION: There is a great lack of empirical evidence on the prevalence, aetiology and prognosis of dyspnoea in general practice. This might yield uncertainty in diagnosis and evaluation of dyspnoea in primary care.

Teaching differential diagnosis in primary care using an inverted classroom approach: student satisfaction and gain in skills and knowledge.

BACKGROUND: Differential diagnosis is a crucial skill for primary care physicians. General practice plays an increasing important role in undergraduate medical education. Via general practice, students may be presented with an overview of the whole spectrum of differential diagnosis in regard to common symptoms encountered in primary care. This project evaluated the impact of a blended learning program (using the inverted classroom approach) on student satisfaction and development of skills and knowledge. METHODS: An elective seminar in differential diagnosis in primary care, which utilized an inverted classroom design, was offered to students. Evaluation followed a mixed methods design: participants completed a pre- and post-test, a questionnaire, and a focus group discussion. Interviews were transcribed verbatim and answers were grouped according to different themes. Test results were analysed using the Wilcoxon matched-pairs signed-ranks test. RESULTS: Participants (n = 17) rated the course concept very positively. Especially the inverted classroom approach was appreciated by all students, as it allowed for more time during the seminar to concentrate on interactive and practice based learning. Students (n = 16) showed a post-test significant overall gain in skills and knowledge of 33%. CONCLUSIONS: This study showed a positive effect of the inverted classroom approach on students' satisfaction and skills and knowledge. Further research is necessary in order to explore the potentials of this approach, especially the impact on development of clinical skills.

Causes of chest pain in primary care--a systematic review and meta-analysis.

AIM: To investigate the frequencies of different and relevant underlying etiologies of chest pain in general practice. METHODS: We systematically searched PubMed and EMBASE. Two reviewers independently rated the eligibility of publications and assessed the risk of bias of included studies. We extracted data to calculate the relative frequencies of different underlying conditions and investigated the variation across studies using forest plots, I(2), tau(2), and prediction intervals. With respect to unexplained heterogeneity, we provided qualitative syntheses instead of pooled estimates. RESULTS: We identified 11 eligible studies comprising about 6500 patients. The overall risk of bias was rated as low in 6 studies comprising about 3900 patients. The relative frequencies of different conditions as the underlying etiologies of chest pain reported by these studies ranged from 24.5 to 49.8% (chest wall syndrome), 13.8 to 16.1% (cardiovascular diseases), 6.6 to 11.2% (stable coronary heart disease), 1.5 to 3.6% (acute coronary syndrome/myocardial infarction), 10.3 to 18.2% (respiratory diseases), 9.5 to 18.2% (psychogenic etiologies), 5.6 to 9.7% (gastrointestinal disorders), and 6.0 to 7.1% (esophageal disorders). CONCLUSION: This information may be of practical value for general practitioners as it provides the pre-test probabilities for a range of underlying diseases and may be suitable to guide the diagnostic process.

Studies of the symptom abdominal pain--a systematic review and meta-analysis.

BACKGROUND: Diagnostic reasoning in primary care patients with abdominal pain is a complex challenge for GPs. To ensure evidence-based decision making for this symptom, GPs need setting-specific knowledge about the prevalence, potential risks for diseases and chance of recovery or risk of undesirable courses of disease. AIM: We conducted a systematic review of symptom-evaluating studies on prevalence, aetiology or prognosis of abdominal pain. METHODS: We included all studies evaluating the symptom 'abdominal pain' as a reason for consultation in primary care. We included all types of study designs except for qualitative studies. Studies focussed solely on children or settings other than primary care were also excluded. RESULTS: We identified 14 studies. Mean consultation prevalence is 2.8% for abdominal pain. In about one-third of patients the underlying cause of abdominal pain cannot be specified. The most common aetiologies are gastroenteritis (7.2-18.7%), irritable bowel disease (2.6-13.2%), urological cause (5.3%) and gastritis (5.2%). About 1 in 10 abdominal pain patients suffers from an acute disease like appendicitis (1.9%), diverticulitis (3.0%), biliary/pancreatic (4.0%) or neoplastic (1.0%) diseases needing immediate therapy. CONCLUSION: There is a high prevalence of patients consulting GPs for abdominal pain. The review identified a comparably high rate of acute underlying diseases in need of further investigation or therapy. At the same time, the underlying cause of the complaints often remains unexplained. Further symptom-evaluating studies are necessary, ideally using standardized methodology in order to gain sufficient evidence for developing much-needed guidelines and decision support tools.

Missing topics for a newly established general practice curriculum for medical students in Hesse - a qualitative study.

BACKGROUND: To address the declining numbers of general practitioners (GPs) in rural areas and a lack of medical students pursuing a career in primary care, a general practice-based curriculum coupled with additional university admissions for students has been established at three universities in Hesse, Germany. This study aims to analyze potential topics which students striving to become a GP will benefit from. Teaching such topics will prepare them for their chosen career and working in rural areas. We aimed to explore the views of both specialists and GPs on chief topics and necessary skills in primary care. METHODS: In our study we used semi-structured interviews with outpatient specialists and specialists in clinical practice and semi-structured group interviews with GPs in training. The topic guide addressed contents of the curriculum for medical students with an extracurricular focus (addressing additional topics) on primary care. Data analysis was carried out using qualitative content analysis according to Mayring. RESULTS: GPs in training and specialists agreed on the importance of knowledge in the fields of medical history, physical examination, communication as well as common diseases in primary care. Essential competences mentioned were: inducing medical treatment, decision-making and triage, conducting structured conversations, having patient knowledge (hard skills) as well as an interest in continuous learning, empathy, personal commitment, listening and down-to-earthness (soft skills). Case reports, symptom-based learning, practical training, lessons with simulated patients and the integration of role models were regarded as useful teaching methods. CONCLUSIONS: General practice-based curriculums should not only focus on the transfer of knowledge. Equally important is the training of soft and hard skills to prepare future GPs for their work in primary care. Special teaching methods as well as practical training should be the heart of a newly established curriculum.

Chest pain in primary care: is the localization of pain diagnostically helpful in the critical evaluation of patients?--A cross sectional study.

BACKGROUND: Chest pain is a common complaint and reason for consultation in primary care. Traditional textbooks still assign pain localization a certain discriminative role in the differential diagnosis of chest pain. The aim of our study was to synthesize pain drawings from a large sample of chest pain patients and to examine whether pain localizations differ for different underlying etiologies. METHODS: We conducted a cross-sectional study including 1212 consecutive patients with chest pain recruited in 74 primary care offices in Germany. Primary care providers (PCPs) marked pain localization and radiation of each patient on a pictogram. After 6 months, an independent interdisciplinary reference panel reviewed clinical data of every patient, deciding on the etiology of chest pain at the time of patient recruitment. PCP drawings were entered in a specially designed computer program to produce merged pain charts for different etiologies. Dissimilarities between individual pain localizations and differences on the level of diagnostic groups were analyzed using the Hausdorff distance and the C-index. RESULTS: Pain location in patients with coronary heart disease (CHD) did not differ from the combined group of all other patients, including patients with chest wall syndrome (CWS), gastro-esophageal reflux disease (GERD) or psychogenic chest pain. There was also no difference in chest pain location between male and female CHD patients. CONCLUSIONS: Pain localization is not helpful in discriminating CHD from other common chest pain etiologies.
