Training in medical communication competence through video-based e-learning: How effective are video modeling and video reflection?

OBJECTIVE: The present study investigated the efficacy of the didactic approaches of video modeling (VM, best-practice examples), video reflection (VR, problem-based approach), and the combination of both (VMR) in fostering medical communication competence in a video-based digital learning environment. METHODS: N = 126 third-year medical students who participated in the pre-post study were assigned to either the intervention groups (VM, VR, and VMR) or the wait-list control group. The efficacy of the three approaches was assessed by means of a situational judgment test (SJT) of medical communication competence. To investigate the differences between the wait-list control and the intervention groups (H1), between the single-mode and combined conditions (H2), and between VM and VR (H3), we applied planned contrast analyses. RESULTS: The planned contrasts showed that the VR condition significantly improved learning outcomes in comparison to the VM condition (H3). The decreased mean scores of the VM condition offset the increased mean scores of VR, and thus no significant differences could be found in H1 and H2. CONCLUSIONS: Our study provides promising evidence that VR fosters medical communication competence more effectively than VM. PRACTICAL IMPLICATIONS: Medical students' learning in video-based digital environments can be facilitated by the use of interactive VR.

What Kind of Patients Receive Inpatient and Day-Hospital Treatment in Departments of Psychosomatic Medicine and Psychotherapy in Germany?

INTRODUCTION: Germany is one of the few countries with a medical specialty of psychosomatic medicine and psychotherapy and many treatment resources of this kind. OBJECTIVE: This observational study describes the psychosomatic treatment programs as well as a large sample of day-hospital and inpatients in great detail using structured diagnostic interviews. METHODS: Mental disorders were diagnosed according to ICD-10 and DSM-IV by means of Mini-DIPS and SCID-II. In addition to the case records, a modified version of the CSSRI was employed to collect demographic data and service use. The PHQ-D was used to assess depression, anxiety, and somatization. RESULTS: 2,094 patients from 19 departments participated in the study after giving informed consent. The sample consisted of a high proportion of "complex patients" with high comorbidity of mental and somatic diseases, severe psychopathology, and considerable social and occupational dysfunction including more than 50 days of sick leave per year in half of the sample. The most frequent diagnoses were depression, somatoform and anxiety disorders, eating disorders, personality disorders, and somato-psychic conditions. CONCLUSIONS: Inpatient and day-hospital treatment in German university departments of psychosomatic medicine and psychotherapy is an intensive multimodal treatment for complex patients with high comorbidity and social as well as occupational dysfunction.

Gender specific somatic symptom burden and mortality risk in the general population.

Gender specific all-cause mortality risk associated with a high somatic symptom burden (SSB) in a population-based cohort was investigated. The study population included 5679 women and 5861 men aged 25-74 years from the population-based MONICA/KORA Cohort. SSB was assessed following the Somatic Symptom Scale-8 and categorized as very high (≥ 95th percentile), high (60-95th percentile), moderate (30-60th percentile), and low (≤ 30th percentile). The impact of SSB on all-cause mortality risk within a mean follow-up period of 22.6 years (SD 7.1; 267,278 person years) was estimated by gender-specific Cox regression models adjusted for sociodemographic, lifestyle, somatic and psychosocial risk factors, as well as pre-existing medical conditions. Approximately 5.7% of men and 7.3% of women had very high SSB. During follow-up, 3638 (30.6%) mortality cases were observed. Men with a very-high SSB had 48% increased relative risk of mortality in comparison to men with a low SSB after adjustment for concurrent risk factors (1.48, 95% CI 1.20-1.81, p < .0001), corresponding to 2% increased risk of mortality for each 1-point increment in SSB (1.02; 95% CI 1.01-1.03; p = 0.03). In contrast, women with a very high SSB had a 22% lower risk of mortality (0.78, 95% CI 0.61-1.00, p = 0.05) and women with high SSB had an 18% lower risk of mortality (0.82; 95% CI 0.68-0.98, p = 0.03) following adjustment for concurrent risk factors. The current findings indicate that an increasing SSB is an independent risk factor for mortality in men but not in women, pointing in the direction of critical gender differences in the management of SSB, including women's earlier health care utilization than men.

[Chronic pain syndromes and other persistent functional somatic symptoms]. / Chronische Schmerzsyndrome und andere persistierende funktionelle Körperbeschwerden.

Somatic symptoms including pain are everyday human experiences. They usually result from a complex interaction of stimuli, interpretation and reaction, and are not necessarily proportional to structural damage. Persistent functional somatic symptoms can be associated with a significant impairment of quality of life and functioning, even without mental or somatic comorbidity. Dysfunctional experiences, expectancies and behavior, not only by patients but also by physicians, can increase the risk of chronification. From the outset, management should be graded with respect to the severity and biopsychosocial aspects, with thorough but cautious diagnostics and with psychoeducative, active and coping-oriented treatment.

Validation of the German version of the Bodily Distress Syndrome 25 checklist in a representative German population sample.

OBJECTIVE: The Bodily Distress Syndrome 25 (BDS 25) checklist is a self-report instrument that can be used for case finding of a BDS in both clinical practice and research. We assessed the reliability and the internal and external validity of the German version of the BDS 25 in a sample of the general German population. METHODS: The psychometric properties of the BDS 25 German were examined in a representative cross-sectional German population survey which included 2386 persons aged ≥14 years. Validation instruments included the Somatic Symptom Scale 8, the Giessen Subjective Complaints List 8 and the Patient Health Questionnaire 4. Participants were asked if they had been diagnosed with fibromyalgia or irritable bowel syndrome by a physician in the past. RESULTS: The acceptance was high. Only 81 (2.3%) single items were not answered. Internal consistency was sufficiently high for all four subscales and the total score (α > 0.800). Exploratory and confirmatory factor analysis revealed clear evidence for a four-factorial structure with cardiopulmonary, gastrointestinal, musculoskeletal and general symptoms. Moderate to high correlations with other measures of somatic and psychological symptom burden were found. In latent class analysis, the model featuring three classes with no, moderate and severe BDS symptoms evinced the best model fit. Participants with self-reported fibromyalgia and irritable bowel syndrome were mainly found in the moderate and severe BDS group. CONCLUSIONS: The BDS 25 German has excellent psychometric properties to screen for BDS in the general population.

Functional Somatic Symptoms.

BACKGROUND: Approximately 10% of the general population and around one third of adult patients in clinical populations suffer from functional somatic symptoms. These take many forms, are often chronic, impair everyday functioning as well as quality of life, and are cost intensive. METHODS: The guideline group (32 medical and psychological professional societies, two patients' associations) carried out a systematic survey of the literature and ana- lyzed 3795 original articles and 3345 reviews. The aim was to formulate empirically based recommendations that were practical and user friendly. RESULTS: Because of the variation in course and symptom severity, three stages of treatment are distinguished. In early contacts, the focus is on basic investigations, reassurance, and advice. For persistent burdensome symptoms, an extended, simultaneous and equitable diagnostic work-up of physical and psychosocial factors is recommended, together with a focus on information and self-help. In the pres- ence of severe and disabling symptoms, multimodal treatment includes further elements such as (body) psychotherapeutic and social medicine measures. Whatever the medical specialty, level of care, or clinical picture, an empathetic professional attitude, reflective communication, information, a cautious, restrained approach to diagnosis, good interdisciplinary cooperation, and above all active interventions for self-efficacy are usually more effective than passive, organ- focused treatments. CONCLUSION: The cornerstones of diagnosis and treatment are biopsychosocial ex- planatory models, communication, self-efficacy, and interdisciplinary mangagement. This enables safe and efficient patient care from the initial presentation onwards, even in cases where the symptoms cannot yet be traced back to specific causes.

The determination of tissue perfusion and collateralization in peripheral arterial disease with indocyanine green fluorescence angiography.

PURPOSE: Indocyanine green (ICG) fluorescence angiography is used to evaluate tissue perfusion in many different medical fields. This study aims to evaluate the value of ICG angiography in the determination of tissue perfusion in the PAD lower extremities. MATERIAL AND METHODS: In a prospective clinical study, ICG angiography was used to evaluate tissue perfusion and collateralization in 30 PAD patients. The perfusion index and maximum fluorescence intensity (MPI) were calculated as arterial perfusion parameters. RESULTS: Significant differences in the perfusion index were found for the different PAD stages (p < 0.001). Poor collateralization was associated with a significantly lower perfusion index than good collateralization (p = 0.003). A ROC analysis for the perfusion index showed a positive likelihood ratio of 6.00 and a negative likelihood ratio of 0.00 with an area under the curve of 0.949 to discriminate critical and non-critical PAD. CONCLUSION: ICG angiography is a promising diagnostic tool to quantify tissue perfusion and demonstrate critical limb ischemia and collateralization in lower extremities affected by PAD.

Early postoperative detection of tissue necrosis in amputation stumps with indocyanine green fluorescence angiography.

OBJECTIVE: Amputations of the lower extremity due to irreversible ischemic tissue loss are performed as distally as possible. Therefore, oftentimes wound-healing disorders develop, requiring additional surgical treatment. METHODS: The amputations stumps of 10 patients with irreversible ischemic tissue loss due to arteriosclerosis were investigated within 72 hours postoperatively with indocyanine green (ICG) fluorescence. RESULTS: For 6 of the investigated stumps, no perfusion deficit could be seen through fluorescence angiography. All stumps displayed primary healing. In the fluorescence angiography of 3 amputations, stump perfusions deficits predicted later tissue necrosis and had to be amputated again in a second operation. One amputation wound showed a small ICG perfusion deficit that represented a blood clot. CONCLUSION: Indocyanine green fluorescence angiography allows a perfusion analysis of amputation stumps and therefore a prediction of the expected tissue necrosis. This tool may allow reliable prediction of amputation level.
