[Statement on the lower age limit for outpatient adenotomies and tonsillotomies]

At the beginning of 2023, there have been significant changes to the regulations for outpatient surgery in Germany, which were set out in a trilateral self-administration agreement between the umbrella association of statutory health insurance companies, the German Hospital Association and the Federal Association of Statutory Health Insurance Physicians. Among other things, a catalog stated circumstances under which an operation should not be carried out on an outpatient basis or should only be carried out with doubt. This catalog explains the patient's age: up to the first year of life, inpatient performance of a service can be justified. This formulation in itself means that children from one year of age on should regularly undergo outpatient surgery.In the german scientific societies for otolaryngology, head and neck surgery as well as for anesthesiology and intensive care medicine, doubts arose as to whether this age limit could also be scientifically justified for operations in the throat such as adenotomy or tonsillotomy.A search was carried out in international guidelines and in the international literature and the statements were evaluated. The results of this literature search were discussed with representatives of the Pediatric Otorhinolaryngology Working Group (AG PädHNO) of the German Society for Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) and the scientific working group for pediatric anesthesia (WAKKA) of the German Society for Anesthesiology and Intensive Care Medicine (DGAI) in conferences.The consensus revealed that a strict age limit of the first year of life is not appropriate for the outpatient performance of adenotomies and tonsillotomies. First of all, specifying a strict age limit is questionable because, regardless of age, a number of other medical and social factors influence the responsible performance of outpatient operations. Furthermore, the age limit of one year is not considered appropriate in view of literature, guidelines and practical experience in the international area. The assessment of the literature and the consideration of the implementation in the international area make an age limit in the range of 2-3 years seem more appropriate.This review provides the responsible doctors with a variety of insights, aspects and arguments so that they can make their decision to carry out these operations on an outpatient or inpatient basis appropriately and responsibly.

[Structure and establishment of the German Cochlear Implant Registry]

Hearing rehabilitation of patients with severe hearing loss or deafness using cochlear implants (CI) is a very successful but also complex and lifelong process that requires high quality standards for structure, process, and results. Medical registries represent an ideal tool for conducting quality control relevant to care while at the same time collecting scientific data. Therefore, at the initiative of the Executive Committee of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery (DGHNO-KHC), a Germany-wide CI registry (the German Cochlear Implant Register, DCIR) was to be established. The following goals were to be achieved: 1) legal and contractual basis for the register; 2) definition of the register contents; 3) development of evaluation standards (hospital-specific and national annual reports); 4) development of a logo; 5) practical operation of the registry. After defining a catalog of services that defines the content, structure, and operation of the DCIR, a registry operator with audiological expertise was sought. After considering various offers, the registry was technically implemented in cooperation with the provider INNOFORCE (Ruggell, Liechtenstein) as registry operator. This also included the realization of an interface for data transfer from previously existing databases and development of a data protection concept for productive operation of the DCIR under the scientific leadership of the DGHNO-KHC Executive Committee. Since January 2022, it has been possible for participating hospitals to enter pseudonymized data into the DCIR. To date, 75 hospitals in Germany have contractually agreed to participate in the registry. During the first 15 months, data from over 2500 implants in over 2000 patients were registered in the DCIR. The work presented here describes the structuring, development, and successful establishment of the DCIR. Introduction of the DCIR represents an important milestone of future scientifically based quality control in CI care. The registry presented here can therefore be considered as an example for other areas of medical care and thus also sets an international standard.

Conception and implementation of a certification system for quality control of cochlear implant treatment in Germany

A standardized and structured process is indispensable for optimal hearing rehabilitation with cochlear implants (CI). The Executive Committee of the German Society of Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC), initiated the conception of a certification program and a Whitepaper based on the Association of the Scientific Medical Societies in Germany (AWMF) clinical practice guideline (CPG) describing the current medical standards of CI care in Germany. The goal was to independently confirm implementation of this CPG and make this information publicly available. With the support of an independent certification organization, successful implementation of the CI-CPG by a hospital would then be verified and confirmed by awarding the "Cochlear implant-provision institution" (Cochlea-Implantat-versorgende Einrichtung, CIVE) quality certificate. A structure for implementation of a certification system was developed based on the CI-CPG. The following steps were required: 1) conception of a quality control system for certification of hospitals working in accordance with the CI-CPG; 2) development of required structures for an independent review of quality-relevant structure, process, and result parameters; 3) development of a standard procedure for independent certification of hospitals; 4) development of a certificate and a logo to demonstrate successful certification; 5) practical implementation of the certification. Following design of the certification program and the required organizational structure, the certification system was successfully launched in 2021. Applications for the quality certificate could be formally submitted from September 2021. A total of 51 off-site evaluations were performed by December 2022. In the first 16 months from introduction, 47 hospitals were successfully certified as CIVE. In this period, 20 experts were trained as auditors, who have since then carried out 18 on-site audits in hospitals. In summary, the conceptual design, structure, and practical implementation of a certification program for quality control in CI care was successfully implemented in Germany.

Magnetron sputter deposition of Ta2O5-SiO2 quantized nanolaminates

Quantized nanolaminates are a type of optical metamaterials, which were discovered only recently. Their feasibility was demonstrated by atomic layer deposition and ion beam sputtering so far. In this paper, we will report on the successful magnetron sputter deposition of quantized nanolaminates based on Ta₂O₅-SiO₂. We will describe the deposition process, show results and material characterization of films deposited in a very wide parameter range. Furthermore, we will show how quantized nanolaminates deposited by magnetron sputtering were used in optical interference coatings such as antireflection and mirror coatings.

Treatment management and outcome of polytraumatized patients in a German certified trauma center - comparing standard versus maximum care

German hospitals are classified as basic, standard and maximum care facilities within the German trauma networks. The Municipal Hospital Dessau was upgraded in 2015 as a maximum care provider. The aim of this study is to investigate whether a change in treatment management and outcome of polytraumatized patients has occurred afterwards. The study compared polytraumatized patients, treated in the Dessau Municipal Clinic as a standard care facility (DessauStandard) from 2012-2014 vs. those treated in the Dessau Municipal Clinic as a maximum care facility (DessauMax) from 2016-2017. Data of the German Trauma Register were analysed using the chi-square test, t-test and odds ratios with 95% confidence intervals.In DessauMax (238 patients; Ø 54 years, SD 22.3; ♂ 160, ♀ 78), the shock room time with 40.7 min (SD 21.4) was shorter than in DessauStandard (206 patients; Ø 56.1 years, SD 22.1; ♂ 133, ♀ 73 ) with 49 min (SD 25.1) (p=0.001). The transfer rate of 1.3% (n=3) to another hospital was lower in DessauMax (p=0.01). DessauStandard had 9 (4%) thromboembolic events and DessauMax 3 (1.3%) (p=0.7). Multiorgan failure was more common in DessauStandard, (16%) than in DessauMax (1.3%; p=0,001). DessauStandard showed a mortality of 13.1% (n=27), and DessauMax 9.2% (n=22) (p=0.22; OR=0.67, 95% CI, 0.37-1.23). The GOS in DessauMax (4.5, SD 1.2) was higher than in DessauStandard (4.1, SD 1.3) (p=0.002).The Dessau Municipal Clinic as a maximum care facility has achieved improved shock room time, fewer complications, lower mortality and an improved outcome.

The impact of a structured one-day seminar on disease-specific knowledge, lifestyle habits and disease impairment in ANCA-associated vasculitis. Results of a randomized, controlled study

OBJECTIVE

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a complex, chronic autoimmune disease, and its diagnosis triggers considerable anxiety and uncertainty for those affected. There are currently no valid data describing the impact of disease-specific patient education on the disease knowledge, subjective impairment, and changes in lifestyle habits related to AAV.

METHOD

We designed a one-day educational programme to serve AAV patients with information about their disease and its treatment. Patients were randomized into an intervention group and a waiting list control group. Increase in knowledge was measured with a multiple-choice test. The intervention group completed the questionnaire before, directly after, and 3 months after the seminar, while the waiting list control group was additionally tested 3 months before the seminar to rule out non-specific learning. Furthermore, we investigated the burden of the disease and the impact of our intervention on this burden.

RESULTS

Compared with the control group, the intervention increased the knowledge (mean ± sd score difference 2.2 ± 1.0, 95% confidence interval 0.1-4.3, p = 0.04). From the patients' point of view, their understanding of the disease had improved and the subjective impairment caused by their rheumatic disease had decreased. There was a tendency to include disease-relevant behaviour, such as nasal care or dietary recommendations, more often in everyday life.

CONCLUSION

A one-day seminar is suitable to increase the disease-specific knowledge of patients with AAV in a sustainable manner. In addition, our measure positively affected the disease-relevant behaviour.

Quality of life assessment in breast cancer patients during palliative treatment in Indonesia

Background

This study aimed to prospectively assess quality of life (QOL), QOL domains, and pain severity in advanced stage breast cancer patients during palliative oncology treatment in Indonesia.

Methods

Advanced stage breast cancer patients > 18 years (n = 160) who began palliative oncology treatment were enrolled in the study using convenience sampling. They completed the EORTC QLQ-C15-PAL questionnaire and pain severity (Visual Analogue Scale, VAS) score at three-time points (baseline (T0), three-(T1) and six-months (T2) follow-up). The repeated measures analysis of variance (ANOVA) model was used to assess the QOL, QOL domains, and pain severity changes over time adjusted for age, place of residence, marital status, and Karnofsky Performance Status score at baseline. We classified the change over time in three qualitative groups (deterioration, improvement, or trivial/no difference). We considered it clinically relevant if patients had a 10-point difference.

Results

The mean age of included patients (n = 159) was 50 years. Most lived in an urban area (72.3%), had low education (71.7%), and were married (81.8%). The repeated measures ANOVA showed that the QOL score, emotional functioning, fatigue, dyspnea, appetite loss, constipation, and VAS pain score remained stable over the 6-months period. In contrast: physical functioning declined (medium to large deterioration (-19.8 (95% CI -27.2 to -12.5)) between T0 to T2), however there was an improvement in the insomnia domain (medium improvement (-13.4 (95% CI -19.9 to -6.9)) between T0 to T2).

Conclusions

Our findings indicated that advanced stage breast cancer patients adapted well to palliative oncology treatment over six months of observation. There was deterioration in physical functioning, but improvement in insomnia. However, more attention is needed from clinicians to achieve improvement in the overall QOL score and specific QOL domains.

Key messages

• Focusing on improvement overall QOL score and specific QOL domains will lead to better advanced stage breast cancer patients’ satisfaction and care.

• Information is limited on palliative treatment satisfaction in low and lower middle-income countries, therefore this study has important impact on further policy considerations in Indonesia.

[Platelet function disorder in trauma patients, an underestimated problem? Results of a single center study]

BACKGROUND

Plasmatic coagulation disorders in trauma patients are common and their management is subject to current guidelines. Less evidence exists for platelet function. Although it is known that several trauma-associated factors have a negative influence on platelet function, routine monitoring has not yet become established.

METHODS

A retrospective single center study was carried out at a German level 1 trauma center from 2010 to 2016. In all patients fulfilling the requirements for the German Trauma Society (DGU) Traumaregister® who were admitted directly from the scene of the incident, platelet function was analyzed using the Platelet Function Analyzer (PFA 100®) with adenosine diphosphate (ADP) and epinephrine as activation factors. After exclusion of patients with intake of long-term anticoagulant and antiaggregant medication, possible influencing factors of a reduced platelet function were identified.

RESULTS

The results from 310 patients (44.0 ± 14.7 years, 76% male, Injury Severity Score, ISS 28.4 ± 14.2 points) were available. A delayed platelet activation was found in 25.5% using ADP and 31% using epinephrine. Laboratory parameters indicated a greater blood loss. Prolonged closure times were associated with an increased transfusion rate of packed red blood cell concentrates and a higher mortality rate. Logistic regression revealed hemoglobin (Hb) and fibrinogen levels at admission to be independent predictors for a decreased platelet activation in the assay with ADP (p < 0.001, Cohen's f = 0.61) and with epinephrine (p < 0.001, f = 0.42).

CONCLUSION

Approximately one quarter to one third of primarily admitted trauma patients without long-term anticoagulation medication showed a delayed platelet activation in the PFA-100 test. By considering all trauma patients an even higher rate can be expected. The Hb and fibrinogen levels at admission can be helpful to estimate platelet disorders. The development of platelet assays to guide the resuscitation of individual patients seems to be absolutely necessary. The contribution of platelet disorders to trauma-induced coagulopathy is not sufficiently understood. Regarding the importance assigned to platelet transfusion or administration of desmopressin, these aspects should be the subject of further research.

Wie würden Sie entscheiden?

Die Patientenaufklärung ist mittlerweile auch in Arztkreisen zu einer allseits anerkannten und zentralen ärztlichen Verpflichtung geworden. Die Patientenaufklärung in Klinik und Praxis zählt neben der standardgemäßen Behandlung und der Dokumentation zu den Kardinalpflichten des ärztlichen Berufes. Auch der Gesetzgeber hat die Patientenaufklärung mit den Bestimmungen des Patientenrechtegesetzes zu einem zentralen Element der ärztlichen Behandlung erhoben. Ungeachtet dessen gibt es nach wie vor eine Vielzahl von sog. Arzthaftungsklagen, die sich auf eine Verletzung der ärztlichen Aufklärungspflicht stützen und damit in vielen Fällen Erfolg haben.

Vorsicht bei Patientenfotos und Videodokumentation im Vortrag, bei Publikationen oder auf der Praxishomepage

Bei medizinisch-wissenschaftlichen Vorträgen, bei ärztlichen Fort- und Weiterbildungsveranstaltungen, in Fachzeitschriften und auch in der medizinischen Forschung werden regelmäßig Abbildungen von Patienten zur Veranschaulichung von Krankheitsbildern, Behandlungsverfahren oder intraoperativer Situationen verwendet. Dies geschieht in Form der Präsentation von Röntgenbildern, intraoperativen Foto- oder Videoaufnahmen oder Bildern von Körperteilen. Auch bei der Darstellung einzelner ärztlicher Tätigkeiten oder Behandlungsverfahren ist es jedenfalls für bestimmte Eingriffe zulässig, Vorher- und Nachher-Bilder von Patienten auf der Praxishomepage zu veröffentlichen oder in der Praxis oder bei Vorträgen vorzustellen. Die Verwendung und Präsentation solcher Bilder von Patienten oder Abbildungen von Körperteilen ist gerade in der ärztlichen Ausbildung, bei Vorträgen und auch in wissenschaftlichen Publikationen geradezu an der Tagesordnung und selbstverständlich. Dennoch sollte man sich dabei im Klaren darüber sein, dass die Rechte der abgebildeten Persönlichkeiten und derjenigen, welche die Abbildungen (Fotos, Röntgenbilder etc.) hergestellt haben, nicht verletzt werden dürfen. Welche Aspekte hierbei zu beachten sind und wie man sich vor Ansprüchen Dritter auf Unterlassung und Schadensersatz am besten schützen kann, stellen wir im nachfolgenden Beitrag vor:

Rechtliche Aspekte der Digitalisierung in der Medizin

Die Digitalisierung unserer Gesellschaft, unseres Handelns und unseres Denkens wird allerorten diskutiert; in Anlehnung an ein literarisch bekannt gewordenes gallisches Dorf könnte man meinen, dass sich nur wenige Unbeugsame dem digitalen Zeitalter entgegenstemmen. Auch und gerade im Gesundheitswesen ist die Digitalisierung derzeit eines der brennendsten Themen in der Gesundheitspolitik und in aktuellen Gesetzgebungsverfahren. So hat die Bundesregierung im Koalitionsvertrag vom 14.03.2018 festgehalten, dass bis 2020 ein Aktionsplan mit konkreten Maßnahmen entwickelt werden soll. Auch die aktuellen Diskussionen um die Einführung und den Nutzungsumfang der elektronischen Gesundheitskarte dominieren weiterhin in den Medien. Nicht zu vergessen ist auch die Debatte um die Lockerung des Fernbehand-lungsverbotes, für welche sich eine große Mehrheit auf dem 121. Ärztetag im Mai 2018 ausgesprochen hat. Letztlich nimmt das Thema Digitalisierung durch die damit einhergehenden datenschutzrechtlichen Fragen an Fahrt auf; wer denkt dieser Tage dabei nicht an die EU-Datenschutzgrundverordnung (DSGVO) und die Neufassung des Bundesdatenschutzgesetzes (BDSG)?

The effectiveness of the paclitaxel-coated Luminor® balloon catheter versus an uncoated balloon catheter in superficial femoral and popliteal arteries in preventing vessel restenosis or reocclusion: study protocol for a randomized controlled trial

BACKGROUND

The aim of this investigator-initiated trial is to evaluate the safety and efficacy of the novel Luminor® paclitaxel-coated drug-eluting balloon (DEB) catheter (iVascular, S.L.U., Barcelona, Spain) in inhibiting restenosis and in ensuring long-term vascular patency.

METHODS/DESIGN

This is a multicenter randomized controlled trial to evaluate the Luminor® paclitaxel-coated DEB catheter for stenotic or occlusive lesions (length ≤15 cm) in the superficial femoral artery (SFA) and the popliteal artery (PA) up to the P1 segment compared to the noncoated, plain old balloon angioplasty (POBA) catheter. In total 172 subjects will be treated with either the DEB catheter or the POBA catheter in 11 German study centers in a 1:1 randomization study design. The primary endpoint is late lumen loss (LLL) at 6 months. Secondary endpoints are patency rate, target lesion/vessel revascularization, quality of life (assessed with the Walking Impairment Questionnaire (WIQ) and the EQ-5D), change of Rutherford stage and ankle-brachial index, major and minor amputation rate at the index limb, number of dropouts and all-cause mortality.

DISCUSSION

EffPac represents a randomized controlled trial that will provide evidence on the effectiveness of the Luminor® paclitaxel-coated DEB catheter for the reduction of restenosis compared to the POBA catheter for the SFA and the PA. The results of EffPac will allow direct comparison to other already-completed RCTs applying paclitaxel-coated DEBs from different manufacturers with different coating technologies in the same target vessel.

TRIAL REGISTRATION

ClinicalTrials.gov Identifier: NCT02540018 , registered on 17 August 2015. Protocol version: CIP Version Final04, 11 February 2016. EUDAMED No: CIV-15-03-013204.

[Adherence to Phase III Cardiac Rehabilitation Programs: A Prospective, Randomized Comparison between a Conventionally Conducted Program and a Tai Chi-Based Program]

INTRODUCTION

In patients with cardiac diseases, lifestyle changes such as an increase in physical activity are recommended to prevent further cardiac events. In Germany this is possible by attending outpatient heart groups. A problem inherent in these programs is the lack of adherence since more than two thirds of patients stop attending cardiac rehabilitation programs after six months. An alternative to the conventional implementation of heart groups is Tai Chi, which was found to improve adherence to cardiac rehabilitation programs in international studies.

METHODS

Patients were randomly assigned to a conventional heart group or a heart group with Tai Chi exercises. At the beginning of the study, a medical history was taken and physical and instrumental tests were carried out, including an assessment of anxiety/depression (HADS questionnaire) and physical well-being (SD-12). Follow-up tests were performed every three months.

RESULTS

Patients were 62.6 ± 8.5 years old, the mean BMI was 28.6 ± 62 kg/m(2), and the proportion of women was 29.8 %. The groups were different in terms of age (conventional heart group: 65.0 ± 7.5; Tai Chi group: 59.9 ± 8.9 years). Therefore, age-adjusted analyses were performed in addition to the planned analyses. Regarding the primary endpoint of the study, there was no difference between the groups. After twelve months, 50 % of subjects were active in the Tai Chi group and 48 % in the conventional heart group (odds ratio 0.92, p = 0.891). After adjustment for age by logistic regression, the odds ratio was 0.47 (p = 0.285). Furthermore, both the participation period in weeks (Tai Chi group: 43.3 ± 26.0; conventional group: 45.5 ± 24.2, p = 0.766) and the participation rate (Tai Chi group: 66.8 ± 19.2 % Tai Chi, conventional group: 76.3 ± 16.5 %, p = 0.074) did not differ between the two groups. A further analysis showed a non-significant trend for improvement of anxiety, depression and physical well-being in the Tai Chi group compared with the conventional group.

CONCLUSION

The insight gained in international studies regarding a better adherence to Tai Chi-guided prevention programs was not transferable to heart group participants from Germany. However, there was a trend regarding a better mental condition in the Tai Chi group.
