The Patient's Perspective
It is the aim of the Leopoldina Symposium “Mission-Innovation” to discuss interdisciplinary possibilities, challenges and responsibilities of telematik, eHealth and High Definition Medicine, as well as the resulting innovation potential in acute medicine so that we can apply it for the benefit of patients. In order to be able to evaluate the potential and the benefits for our patients, it is crucial to engage with the patient perspective
Embodiment of the Macbeth effect is mapped topographically onto the somatosensory cortex
The theory of embodied cognition claims that knowledge is represented in modal
systems derived from perception. Recent behavioral studies found evidence for
this hypothesis, for example, by linking moral purity with physical cleansing
(the Macbeth effect). Neurophysiological approaches provided further support
by showing an involvement of sensorimotor cortices for embodied metaphors.
However, the exact role of this brain region for embodied cognitions remains
to be cleared. Here we demonstrate that the involvement of the sensorimotor
cortex for the embodied metaphor of moral-purity is somatotopically organized.
Participants enacted in scenarios where they had to perform immoral or moral
acts either with their mouths or their hands. Results showed that mouthwash
products were particularly desirable after lying in a voice mail and hand wash
products were particularly desirable after writing a lie, thus demonstrating
that the moral-purity metaphor is specific to the sensorimotor modality
involved in earlier immoral behavior. FMRI results of this interaction showed
activation in sensorimotor cortices during the evaluation phase that was
somatotopically organized with respect to preceding lying in a voice mail
(mouth-area) or in a written note (hand-area). Thus, the results provide
evidence for a central role of the sensorimotor cortices for embodied
metaphors
Personal involvement is related to increased search motivation and associated with activity in left BA44 - a pilot study
Numerous studies explore consumer perception of brands in a more or less
passive way. This may still be representative for many situations or decisions
we make each day. Nevertheless, sometimes we often actively search for and use
information to make informed and reasoned choices, thus implying a rational
and thinking consumer. Researchers suggested describing this distinction as
low relative to high involvement consumer behavior. Although the involvement
concept has been widely used to explain consumer behavior, behavioral and
neural correlates of this concept are poorly understood. The current study
aims to describe a behavioral measure that is associated with high
involvement, the length of search behavior. A second aim of this study was to
explore brain activations associated with involvement by employing functional
magnetic resonance imaging (fMRI). We presented participants information cues
for different products and told them that they had to answer questions with
respect to these products at the end of the experiment. Participants were free
to stop the information search if they think they gathered enough information
or to continue with collecting information. Behavioral results confirmed our
hypothesis of a relationship between searching behavior and personal
involvement by demonstrating that the length of search correlated
significantly with the degree of personal involvement of the participants.
fMRI data revealed that personal involvement was associated with activation in
BA44. Since this brain region is known to be involved in semantic memory, the
results of this pilot study suggest that high involvement consumer behavior
may be linked to cognitive load and attention towards a product
Retrospective Study on Ganglionic and Nerve Block Series as Therapeutic Option for Chronic Pain Patients with Refractory Neuropathic Pain
Objective. Current recommendations controversially discuss local infiltration techniques as specific treatment for refractory pain syndromes. Evidence of effectiveness remains inconclusive and local infiltration series are discussed as a therapeutic option in patients not responding to standard therapy. The aim of this study was to investigate the effectiveness of infiltration series with techniques such as sphenopalatine ganglion (SPG) block and ganglionic local opioid analgesia (GLOA) for the treatment of neuropathic pain in the head and neck area in a selected patient group. Methods. In a retrospective clinical study, 4960 cases presenting to our university hospital outpatient pain clinic between 2009 and 2016 were screened. Altogether, 83 patients with neuropathic pain syndromes receiving local infiltration series were included. Numeric rating scale (NRS) scores before, during, and after infiltration series, comorbidity, and psychological assessment were evaluated. Results. Maximum NRS before infiltration series was median 9 (IQR 8–10). During infiltration series, maximum NRS was reduced by mean 3.2 points (SD 3.3, p < 0.001) equaling a pain reduction of 41.0% (SD 40.4%). With infiltration series, mean pain reduction of at least 30% or 50% NRS was achieved in 54.2% or 44.6% of cases, respectively. In six percent of patients, increased pain intensity was noted. Initial improvement after the first infiltration was strongly associated with overall improvement throughout the series. Conclusion. This study suggests a beneficial effect of local infiltration series as a treatment option for refractory neuropathic pain syndromes in the context of a multimodal approach. This effect is both significant and clinically relevant and therefore highlights the need for further randomized controlled trials
A Case of Right Alien Hand Syndrome Coexisting with Right-Sided Tactile Extinction
The alien hand syndrome (AHS) is a fascinating movement disorder. Patients
with AHS experience one of their limbs as alien, which acts autonomously and
performs meaningful movements without being guided by the intention of the
patient. Here, we report a case of a 74-years old lady diagnosed with an
atypical Parkinson syndrome by possible corticobasal degeneration. The patient
stated that she could not control her right hand and that she felt like this
hand had her own life. We tested the patient for ownership illusions of the
hands and general tactile processing. Results revealed that when blindfolded,
the patient recognized touch to her alien hand only if it was presented
separated from touch to the other hand (bilateral asynchronous touch).
Delivering touch synchronously to both the alien and the healthy hand resulted
in failure of recognizing touch to the alien hand (bilateral synchronous
touch). Thus, AHS here co-existed with right-sided tactile extinction and is
one of only very few cases in which the alien hand was felt on the right side.
We discuss the results in the light of recent research on AHS
Supplementing transcranial direct current stimulation to local infiltration series for refractory neuropathic craniocephalic pain: A randomized controlled pilot trial
Background: Some patients with neuralgia of cranial nerves with otherwise therapy-refractory pain respond to invasive therapy with local anesthetics. Unfortunately, pain regularly relapses despite multimodal pain management. Transcranial direct current stimulation (tDCS) may prolong pain response due to neuro-modulatory effects.
Methods: This controlled clinical pilot trial randomized patients to receive anodal, cathodal or sham-tDCS stimulation prior to local anesthetic infiltration. Pain attenuation, quality-of-life and side effects were assessed and compared with historic controls to estimate effects of tDCS stimulation setting.
Results: Altogether, 17 patients were randomized into three groups with different stimulation protocols. Relative reduction of pain intensity in per protocol treated patients were median 73%, 50% and 69% in anodal, cathodal and sham group, respectively (p = 0.726). Compared with a historic control group, a lower rate of responders with 50% reduction of pain intensity indicates probable placebo effects (OR 3.41 stimulation vs. non-stimulation setting, NNT 3.63). 76.9% (n = 10) of tDCS patients reported mild side-effects. Of all initially included 17 patients, 23.5% (n = 4) withdrew their study participation with highest proportion in the cathodal group (n = 3). A sample size calculation for a confirmatory trial revealed 120 patients using conservative estimations.
Discussion: This pilot trial does not support series of anodal tDCS as neuro-modulatory treatment to enhance pain alleviation of local anesthetic infiltration series. Notably, results may indicate placebo effects of tDCS settings. Feasibility of studies in this population was limited due to relevant drop-out rates. Anodal tDCS warrants further confirmation as neuro-modulatory pain treatment option
Diagnostic Performance of Self-Assessment for Constipation in Patients With Long-Term Opioid Treatment
Constipation is a prevalent comorbidity affecting ∼50% of patients with long-
term opioid therapy. In clinical routine different diagnostic instruments are
in use to identify patients under risk. The aim of this study was to assess
the diagnostic performance of an 11-item Likert scale for constipation used as
a self-assessment in opioid-treated patients. This trial was conducted as a
retrospective cohort study in Berlin, Germany. Patients with long-term opioid
therapy treated in 2 university-affiliated outpatient pain facilities at the
Charité hospital were included from January 2013 to August 2013. Constipation
was rated in a self-assessment using a numeric rating scale from 0 to 10 (Con-
NRS) and compared with results from a structured assessment based on ROME-III
criteria. Altogether, 171 patients were included. Incidence of constipation
was 49% of patients. The receiver-operating characteristic of Con-NRS achieved
an area under the curve of 0.814 (AUC 95% confidence interval 0.748–0.880, P <
0.001). Con-NRS ≥ 1 achieved sensitivity and specificity of 79.7% and 77.2%,
respectively. The positive predictive value and the negative predictive value
were 70.3% and 81.6%, respectively. Overall diagnostic performance of a
concise 11-item Likert scale for constipation was moderate. Although patients
with long-term opioid therapy are familiar with numeric rating scales, a
significant number of patients with constipation were not identified. The
instrument may be additionally useful to facilitate individualized therapeutic
decision making and to control therapeutic success when measured repetitively
Patients’ self‐reported physical and psychological effects of opioid use in chronic noncancer pain—A retrospective cross‐sectional analysis
Background: Strong opioids can have unintended effects. Clinical studies of strong opioids mainly report physical side effects, psychiatric or opioid use disorders. To date, too little attention has been paid to the psychological effects of opioids to treat patients with chronic noncancer pain (CNCP). This study aims to identify and measure (i) the nature and frequency of physical and psychological effects and (ii) the degree of physician counseling of patients with CNCP taking strong opioids.
Methods: Within a cross-sectional survey-conducted as part of a randomised controlled online intervention trial (ERONA [Experiencing the risk of overusing opioids among patients with chronic non-cancer pain in ambulatory care])-300 German CNCP patients were surveyed via patient-reported outcome measures regarding on both the side effects from their use of strong opioids as well as their counselling experience.
Results: Among the patients' reported effects, the psychological outcomes of the opioids in CNCP were: feeling relaxed (84%), fatigue (76%), dizziness (57%), listlessness (37%), difficulty with mental activities (23%), dulled emotions (17%) and poor memory (17%). Ninety-two per cent of the patients reported having received information about opioid effects, and 46% had discussed cessation of the opioid medication with their physicians before commencing the prescription.
Conclusions: In addition to the well-known physical side effects, patients with CNCP taking strong opioids experience significant psychological effects. In view of these effects, discontinuation of opioid therapy should be discussed early to ensure their benefits do not outweigh their harm.
Significance: In this study, patients with non-cancer pain notice that opioids they have taken do not only cause physical side effects but also may have an impact on their psyche and their emotions and, thus, may also affect quality of life substantially.

Perceived Severity of Stressors in the Intensive Care Unit: A Systematic Review and Semi-Quantitative Analysis of the Literature on the Perspectives of Patients, Health Care Providers and Relatives
The aim of this study was to synthesize quantitative research that identified ranking lists of the most severe stressors of patients in the intensive care unit, as perceived by patients, relatives, and health care professionals (HCP). We conducted a systematic literature search in PubMed, MEDLINE, EMBASE, PsycInfo, CINAHL, and Cochrane Library from 1989 to 15 May 2020. Data were analyzed with descriptive and semi-quantitative methods to yield summarizing ranking lists of the most severe stressors. We synthesized the results of 42 prospective cross-sectional observational studies from different international regions. All investigations had assessed patient ratings. Thirteen studies also measured HCP ratings, and four studies included ratings of relatives. Data indicated that patients rate the severity of stressors lower than HCPs and relatives do. Out of all ranking lists, we extracted 137 stressor items that were most frequently ranked among the most severe stressors. After allocation to four domains, a group of clinical ICU experts sorted these stressors with good to excellent agreement according to their stress levels. Our results may contribute to improve HCPs' and relatives' understanding of patients' perceptions of stressors in the ICU. The synthesized stressor rankings can be used for the development of new assessment instruments of stressors
Effectiveness of an intensive care telehealth programme to improve process quality (ERIC): a multicentre stepped wedge cluster randomised controlled trial
Purpose!#!Supporting the provision of intensive care medicine through telehealth potentially improves process quality. This may improve patient recovery and long-term outcomes. We investigated the effectiveness of a multifaceted telemedical programme on the adherence to German quality indicators (QIs) in a regional network of intensive care units (ICUs) in Germany.!##!Methods!#!We conducted an investigator-initiated, large-scale, open-label, stepped-wedge cluster randomised controlled trial enrolling adult ICU patients with an expected ICU stay of ≥ 24 h. Twelve ICU clusters in Berlin and Brandenburg were randomly assigned to three sequence groups to transition from control (standard care) to the intervention condition (telemedicine). The quality improvement intervention consisted of daily telemedical rounds guided by eight German acute ICU care QIs and expert consultations. Co-primary effectiveness outcomes were patient-specific daily adherence (fulfilled yes/no) to QIs, assessed by a central end point adjudication committee. Analyses used mixed-effects logistic modelling adjusted for time. This study is completed and registered with ClinicalTrials.gov (NCT03671447).!##!Results!#!Between September 4, 2018, and March 31, 2020, 1463 patients (414 treated on control, 1049 on intervention condition) were enrolled at ten clusters, resulting in 14,783 evaluated days. Two randomised clusters recruited no patients (one withdrew informed consent; one dropped out). The intervention, as implemented, significantly increased QI performance for 'sedation, analgesia and delirium' (adjusted odds ratio (99.375% confidence interval [CI]) 5.328, 3.395-8.358), 'ventilation' (OR 2.248, 1.198-4.217), 'weaning from ventilation' (OR 9.049, 2.707-30.247), 'infection management' (OR 4.397, 1.482-13.037), 'enteral nutrition' (OR 1.579, 1.032-2.416), 'patient and family communication' (OR 6.787, 3.976-11.589), and 'early mobilisation' (OR 3.161, 2.160-4.624). No evidence for a difference in adherence to 'daily multi-professional and interdisciplinary clinical visits' between both conditions was found (OR 1.606, 0.780-3.309). Temporal trends related and unrelated to the intervention were detected. 149 patients died during their index ICU stay (45 treated on control, 104 on intervention condition).!##!Conclusion!#!A telemedical quality improvement program increased adherence to seven evidence-based German performance indicators in acute ICU care. These results need further confirmation in a broader setting of regional, non-academic community hospitals and other healthcare systems
