Modifications of Surgical Suction Tip Geometry for Flow Optimisation: Influence on Suction-Induced Noise Pollution.

INTRODUCTION: Suction devices for clearing the surgical field are among the most commonly used tools of every surgeon because a better view of the surgical field is essential. Forced suction may produce disturbingly loud noise, which acts as a nonnegligible stressor. Especially, in emergency situations with heavy bleeding, this loud noise has been described as an impeding factor in the medical decision-making process. In addition, there are reports of inner ear damage in patients due to suction noises during operations in the head area. These problems have not been solved yet. The purpose of this study was to analyse flow-dependent suction noise effects of different surgical suction tips. Furthermore, we developed design improvements to these devices. METHODS: We compared five different geometries of suction tips using an in vitro standardised setup. Two commercially available standard suction tips were compared to three adapted new devices regarding their flow-dependent (10-2000 mL/min) noise emission (dB, weighting filter (A), distance 10 cm) and acoustic quality of resulting noises (Hamilton fast Fourier analysis) during active suction at the liquid-air boundary. Noise maps at different flow rates were created for all five suction devices, and the proportion of extracted air was measured. The geometries of the three custom-made suction tips (new models 1, 2, and 3) were designed considering the insights after determining the key characteristics of the two standard suction models. RESULTS: The geometry of a suction device tip has significant impact on its noise emission. For the standard models, the frequency spectrum at higher flow rates significantly changes to high-frequency noise patterns (>3 kHz). A number of small side holes designed to prevent tissue adhesion lead to increased levels of high-frequency noise. Due to modifications of the tip geometry in our new models, we are able to achieve a highly significant reduction of noise level at low flow rates (new model 2 vs. standard models p < 0.001) and also the acoustic quality improved. Additionally, we attain a highly significant reduction of secondary air intake (new model 2 vs. the other models p < 0.001). CONCLUSION: Improving flow-relevant features of the geometry of suction heads is a suitable way to reduce noise emissions. Optimized suction tips are significantly quieter. This may help us to reduce noise-induced hearing damage in patients as well as stress of medical staff during surgery and should lead to quieter operation theatres overall. Furthermore, the turbulence reduction and reduced secondary air intake during the suction process are expected to result in protective effects on the collected blood and thus could improve the quality of autologous blood retransfusions. We are on the way to evaluate potential benefits.

[Physicians' knowledge on cancer pain therapy : Comparison of palliative care and prehospital emergency physicians in training]. / Wissen verschiedener Arztgruppen über die Tumorschmerztherapie : Vergleich angehender Palliativ- und Notfallmediziner.

BACKGROUND: Palliative care needs a high level of expertise. In particular, there are some potential difficulties in the treatment of patients with the symptom cancer pain (for example lack of education). In Germany, various physicians are involved in cancer pain treatment but in general palliative care patients are treated by a physician who is educated in palliative medicine. In special circumstances prehospital emergency physicians and other physicians are involved in therapy decisions in palliative care patients as well. The authors surveyed different groups of physicians in Germany about their specific knowledge of cancer pain management. MATERIAL AND METHODS: A self-designed, standardized questionnaire (50 items) was given to palliative physicians in training (PP). The survey asked prospectively for knowledge on the World Health Organization (WHO) step ladder of cancer pain therapy. The results were retrolectively compared with an earlier investigation with the same background (emergency physicians in training EP). RESULTS: There was a 99.5% response rate with a total of 654 respondents (PP 185, EP 469) and 461 (70.5%) of the respondents had knowledge of the WHO step ladder for the treatment of cancer pain [PP 164/185 (88.6%), EP 297/469 (63.3%), PP versus EP p < 0.001)]. The correct numbers of therapeutic levels were known by 361/461 participants [PP 151/164 (92.1%), EP 210/297 (70.7%), p < 0.001].The EPs with a professional experience less than 5 years answered statistically significantly more questions correctly (p = 0.004). Concerning the defined parameters knowledge and professional experience, there was no statistically significant difference in the group of PP. CONCLUSIONS: The results of this study verified that the highest knowledge scores were achieved by PPs and overall, the knowledge scores showed an improvement in comparison to previous investigations. In recent years there seems to have been an improvement in education on pain treatment,for example during medical school. Whether this also leads to an improvement of patient care and the relevance of these data for the clinical practice needs to be investigated in further studies.

[Anesthesiology and palliative medicine. Structured results of a prospective questionnaire-based survey in German hospitals]. / Anästhesiologie und Palliativmedizin. Strukturelle Ergebnisse einer prospektiven Umfrage in deutschen Kliniken.

BACKGROUND: Anesthesiology departments were often integrated into the primary formation of palliative activities in Germany. The aim of this study was to present the current integration of anesthesiology departments into palliative care activities in Germany. METHODS: The objective was to determine current activities of anesthesiology departments in in-hospital palliative care. A quantitative study was carried out based on a self-administered structured questionnaire used during telephone interviews. RESULTS: A total of 168 out of 244 hospitals consented to participate in the study and the response rate was 69%. In-hospital palliative care activities were reported for most of the surveyed hospitals. Only two hospitals in the maximum level of care reported no activities. Participation in these activities by anesthesiology departments was described in up to 92%. Historically, most activities are due to the commitment of individuals, whereas the development of palliative care of cancer pain services and hospital support teams took place in the university hospitals by 2005. CONCLUSIONS: Until 2005 many university palliative care activities had their origins in cancer pain services. These were often integrated into anesthesiology departments. Currently, anesthesiology departments work as an integrative part of palliative medicine. However, it appears from the present results that there is a domination of internal medicine (especially hematology and oncology) in palliative activities in German hospitals. This allows the focus of palliative activities to be formed by subjective specialist interests. Such a state seems to be reduced by the integration of anesthesiology departments because of their neutrality with respect to faculty-specific medical interests. Advantages or disadvantages of these circumstances are not considered by the present investigation.

Prehospital emergency physicians' experiences with advance directives in Germany: a questionnaire-based multicenter study.

BACKGROUND: Palliative medical emergencies and end-of-life decisions resulting from the exacerbation of cancer account for approximately 3% of all out-of-hospital emergency applications in Germany. Therefore, prehospital emergency physicians (EP) may be confronted with advance directives and ethical and end-of-life decisions. The purpose of the study was to identify EPs' knowledge about ethical and end-of-life decisions and their legal education and experiences concerning advance directives. METHODS: Over a six-month period, we questioned all 150 EPs from three emergency medical services (Braunschweig, Göttingen und Kaiserslautern). An anonymous, self-administered questionnaire with a mixed-methods design was used. The main outcome measures included responses regarding experiences related to advance directives and end-of-life decisions in palliative care patients. For statistical assessment, EPs were divided into three categories: competent, skilled, and unskilled. RESULTS: A total of 104 EPs returned the questionnaire (response rate 69%). Eighty-nine percent of the respondents treated patients who had advance directives. The existence of an advance directive influenced the EP's therapy decision in about 77% of their encounters. Eighty-seven percent of the EPs reported the need for defined end-of-life care pathways and/or standard operating procedures. Eighty-two percent desired educational training concerning end-of-life decisions and the validity of advance directives. CONCLUSION: The prehospital emergency treatment of palliative care patients can be particularly challenging for any EP. A high percentage of the EPs in our study felt insecure in dealing with advance directives and ethical and end-of-life decisions in palliative care patients. Our results suggest that EPs may need more information and education about palliative medical care, legal issues and ethical and end-of-life decisions to provide adequate patient-oriented palliative care in prehospital emergency situations.

[Cancer pain therapy in palliative care patients: knowledge of prehospital emergency physicians in training. Prospective questionnaire-based investigation]. / Kenntnisse angehender Notfallmediziner über die Tumorschmerztherapie bei Palliativpatienten. Prospektive fragebogenbasierte Untersuchung.

BACKGROUND: Cancer diseases are often associated with acute and chronic pain. Therefore, cancer pain is a symptom frequently reported by palliative care patients with cancer diseases. Prehospital emergency physicians may be confronted with exacerbation of pain in cancer patients. The aim of this study was to evaluate the knowledge of prehospital emergency physicians in training concerning cancer pain therapy. METHODS: A total of 471 prehospital emergency physicians received a questionnaire (period of time: 2007-2009). The questionnaire was prepared for the study ("mixed methods design"). Twenty-four questions concerning cancer pain therapy (response options: scaling, open) were designed. The evaluation was done descriptively according to professional experience, field name and experience in treating patients with cancer as well. RESULTS: A total of 469 participants completed the questionnaire (response rate 99%). On average, 10.8 (SD +5.7, range 2-24) questions were answered correctly. Resident physicians answered statistically significantly more questions correctly than consultants (p=0.02). Only physicians working in internal medicine achieved statistically significantly better results than other disciplines (e.g., surgery; p=0.01). Physicians with professional experience of less than 5 years answered statistically significantly more questions correctly (p=0.004). CONCLUSIONS: The results of this study verify that emergency physicians in training have insufficient knowledge of pain therapy and end-of-life decisions. The data of this investigation suggest that more attention should be paid to education on pain therapy and end-of-life care in medical curricula. Prehospital emergency physicians may thus be better prepared to provide quality care for palliative patients.

[Out-patient and in-hospital palliative care in Germany : Comparison with emergency medical care infrastructure]. / Ambulante und stationäre palliativmedizinische Patientenversorgung in Deutschland : Vergleich zur notfallmedizinischen Infrastruktur.

BACKGROUND: In Germany, specialized out-patient palliative care systems (SPCS) are still structurally and organizationally under construction. Palliative care patients need an easy access to a qualified SPCS. The purpose of the present investigation was to show the nationwide distribution of all SPCS teams in comparison to the distribution of emergency medical systems. Possibilities for an effective structure of palliative medical care systems will be discussed in order to optimize patient care.. METHODS: All SPCS teams in Germany (according to the Guide to hospices and palliative medicine of the German Association for Palliative Care 2008/2009) were documented. A cartographic representation of the structural distribution of palliative care systems was made taking a catchment area diameter of 50 km for each SPCS team and an accessibility diameter of 20 km for every palliative ward into account. These data were compared with the nationwide distribution of emergency institutions. RESULTS: In Germany 25 SPCS teams and 198 palliative wards could be identified. In contrast there are 1,109 emergency physician locations (1,051 ground based, 58 air based). The nationwide distribution of the existing SPCS teams does not at present give exhaustive coverage in comparison to emergency medical structures. No structure which might potentially result in an exhaustive implementation of SPCS teams and palliative stations is recognizable in the analysis or distribution. CONCLUSIONS: The coverage of SPCS and in-hospital palliative care is still a theoretical construct in many regions of Germany. The number of existing SPCS teams and in-patient palliative institutions is insufficient to guarantee an exhaustive coverage of patient care as in emergency medical services. In order to achieve a higher quality of results the quality of the structure and processes must first be ensured. The distribution of palliative care should be centrally coordinated along the same lines as the emergency institutions in order to achieve a need-oriented exhaustive coverage. A surplus of care in some regions at the expense of an undersupply in other regions must be avoided. In the next step a further development and adaption of existing structures to the requirements would be a logical approach.

[Emergency medical treatment of palliative care patients at the end of life: regulatory emergency medical care framework--a case control investigation of medical intervention and advance directives]. / Notfallmedizinische Betreuung von Palliativpatienten am Lebensende : Juristische Beurteilung notfallmedizinischer Handlungsweisen - retrospektive Fallbetrachtung zur medizinischen Indikation und zum Patientenwillen.

BACKGROUND: The treatment of out-of-hospital palliative emergency care situations during cardiac arrest is a special situation. The prehospital emergency physician (EP) and the paramedic must be informed about the medical, legal, and ethical specifics of these situations, but this knowledge is not integrated within emergency medical curricula at all. We present a case study to discuss such legal and ethical specifics. METHODS: We retrospectively analysed six emergency cases with palliative care patients in the final stages of their illnesses. On the basis of these case studies, we present six different emergency cases with different regulatory frameworks for each EP and paramedic. In accordance with the Declaration of Helsinki, data were collected pseudonymously. RESULTS: The six case studies show therapeutic concepts concerning the emergency medical care of palliative care patients during cardiac arrest. The differences are apparent in the treatment given by EPs and by paramedics (such as whether to start or stop resuscitation). EPs and paramedics differ in their therapeutic approach to these specific situations (e.g. paramedics more often start resuscitation during cardiac arrest even though patients would refuse this according to their advance directives). These differences may be important for the patient and his or her caregivers. CONCLUSIONS: Every EP and paramedic may be involved in the care of palliative care patients who are at the end of their lives. EPs and paramedics do not always adapt their treatment to the will or supposed will of the patient (especially in accordance with the new German law concerning advance directives). The reasons for this usually concern legal uncertainties. Therefore, EPs and paramedics should know that different legal meanings could be important in emergency medical care therapy of palliative care patients. A written "do not resuscitate" order as an advance directive must be evaluated as a desired therapeutic limitation.

[Palliative medicine. Fifth pillar of anaesthesia departments]. / Palliativmedizin: Fünfte Säule anästhesiologischer Abteilungen?

Palliative medicine has progressed during recent years to an independent medical faculty within the German health system. Despite this development palliative care systems for out-of-hospital and in-hospital palliative care are still insufficient in Germany so that the development of necessary resources must be considered as not yet completed. To support the further national development palliative medicine can be temporarily or permanently coupled to existing departments, which can be advantageous for all concerned and last but not least be profitable to patients and their relatives. Possibilities for participation of anaesthesiologists in this area of medical care are discussed in the study reported here. Anaesthesiologists have always historically been represented in palliative medical departments, e.g. as pain specialists. In the following investigation the special possibilities of anaesthesia departments for supporting the education and development of in-hospital and out-of hospital palliative medical care departments are reported. Previous experience of co-operation between these two departments is well established. Departments of palliative medicine depend on a well working interdisciplinary co-operation between different medical disciplines (e.g. anaesthesiology, radiotherapy, surgery and oncology) and several medical professions (e.g. physicians, nurses, psychologists). The aim of palliative care therapy is to be responsible for the best possible therapy for cancer patients and to give support to their care-giving relatives. Due to the increasing establishment of palliative care procedures in Germany, departments of anaesthesiology should actively take part in the further development. Part of the responsibility of most anaesthesia departments is to practice pain management and critical care medicine, which are reasons why anaesthesiologists are predestined to be part of the system for palliative care patients and their relatives. Anaesthesia departments can be responsible for the organization of in-hospital and out-of-hospital palliative medicine and palliative care. The integration of anaesthesiological expertise into palliative medicine departments and vice versa can be a great opportunity for both medical departments and therefore represents a worthwhile engagement.

Treatment of palliative care emergencies by prehospital emergency physicians in Germany: an interview based investigation.

Palliative care medical emergencies as a consequence of advanced cancer account for approximately 3% of all prehospital emergency cases. Therefore, prehospital emergency physicians (EP) are confronted with 'end of life decisions'. No educational content exists concerning palliative medicine in emergency medicine curricula. Over the course of 6 months, we interviewed 150 EPs about their experiences in 'end of life decisions' using a specific questionnaire. The total response rate was 69% (n = 104). Most of the interviewed EPs (89%, n = 93) had been confronted with palliative care medical emergencies and expressed uncertainties in dealing with these difficult situations, especially in the area of psychosocial care of the patients (50%). The emergency treatment of palliative care patients can become a particular challenge for any EP. A large percentage of interviewed EPs felt uncertain about aspects of social care and in the assessment of decisions at the end of life. Further information and training are necessary to amenable EPs to provide adequate patient-oriented care to palliative care patients and their relatives in emergency situations.

[Emergency medical care of terminally ill patients]. / Notärztliche Versorgung von Palliativpatienten.

BACKGROUND AND OBJECTIVE: 3 % of all emergency calls in Germany are related to terminally ill cancer patients. It was the aim of this investigation to prospectively include over a lenghty period all emergency calls from cancer patients in the final stage of their disease, to elucidate the specific features of these calls and to compare them with calls of other reasons. METHODS: All "palliative emergency contacts" during a period of six years were included and compared with emergency applications of other causes. RESULTS: 63 emergency calls by cancer patients or their relatives were analysed (3.9 % of all emergency calls). The effort made and the care given to these patients differed significantly from those related to other calls (p < 0.05). Thus acute dyspnoea was the most frequent reason for an emergency call in cancer patients (33.3 % compared with 9.4 %). 93.7 % of the calls were made because of psychosocial strain among the care-giving relatives. Significantly more of these patients were able to remain at home (56.6 %) than in calls for other causes (16.1 %). CONCLUSION: Our data demonstrate that the care of cancer patients in the final stage of their disease is an important factor in emergency medicine. For this reason special knowledge of problems arising in relation to end of life care is essential.

[Palliative care patients in an advanced state of disease. Cardiopulmonary resuscitation and determination of death]. / Palliativpatienten im weit fortgeschrittenen Krankheitsstadium. Notärztliche Reanimation und Todesfeststellung.

BACKGROUND: Prehospital emergency teams will be confronted with the specific needs of resuscitation in palliative patients in whom a return of spontaneous circulation (ROSC) could be found significantly less frequently than in other emergency situations. The present investigation aims to show medical and judicial problems related to cardiopulmonary resuscitation (CPR), external examination of the corpse and death certification. METHODS: Over a 12-month period all emergency cases involving physicians in an out-of-hospital resuscitation setting in cancer patients were retrospectively analysed for indications for emergency call, situation on-site and prehospital treatment by emergency physicians, external examination of the corpse and determination of death. RESULTS: For the period mentioned 164 (2.7% of the total) emergency calls by cancer patients or their relatives were identified. In the following study 43 patients (26.2%) could be included. In 20 cases (46.5%) the emergency physicians attempted to resuscitate the patient by performing CPR. In the majority of cases (36; 83.7%) death certification and external examination of the corpse were necessary at the scene. CONCLUSIONS: Due to a reduced rate of ROSC in palliative patients, death certification and external examination of the corpse are more often necessary than in other emergency situations. Therefore every emergency physician should be familiar with the ethics of resuscitation of patients in palliative care and with external examination of the corpse to do justice to patients and their caregivers.

[The Göttingen palliative emergency card: improvement of emergency medical care for ambulatory palliative care patients. The "yellow card for rescue services"]. / Göttinger Palliativkrisenbogen: Verbesserung der notfallmedizinischen Versorgung von ambulanten Palliativpatienten. Die "Gelbe Karte für den Rettungsdienst."

Currently more and more patients with cancer will be treated at home, especially at the final stage of their disease. Relatives and nursing services will therefore be confronted with acute emergency situations concerning these patients. The handling of these acute situations may be beyond the relatives' coping capacity. For that reason the pre-hospital emergency system (2.5% of all emergency calls) will be confronted with very specific needs of these patients. Emergency situations of palliative patients at home are more predictable than other circumstances. It is thus possible to achieve a practicable preparation for such emergency situations. An individual "emergency plan" should be created for these cases.. The plan may be processed in an emergency situation. It may then be possible to avoid emergency calls and make it possible for the patient to remain at home. This promotes the patient's quality of life and his/her predominant desire to stay at home after the emergency. An advance directive should be made which records the patient's wishes. Because of the complexity of an advance directive it is essential to indicated the patient's wishes in a short and quickly read form in case an emergency arises. This is one of the reasons for producing a short version like the "Göttingen palliative emergency card". In acute situations it is then possible quickly to make known the patient's wishes The patient may be given the possibility of remaining at home after an emergency situation has been dealt with successfully.

[Treatment of oncology patients in the final stadium of disease by prehospital emergency physicians]. / Notärztliche Betreuung von Tumorpatienten in der finalen Krankheitsphase.

BACKGROUND: Presently and even more in the near future more cancer patients will be treated at home especially in the final stage of their disease. For this reason the prehospital emergency system will be confronted with the specific needs of these patients. Palliative care is not part of the German model of post-graduate training regulations for emergency medicine and palliative care teams (PCT) are only involved in the treatment of cancer patients in emergency situations. METHODS: Over a 12-month period we retrospectively analysed all emergency cases that had been categorised as final cancer stage at 2 emergency sites (one air-based, the other ground-based) involving physicians in an out-of-hospital setting. We analysed all cases for indications of emergency call, prehospital treatment and involvement of a PCT in the treatment of symptoms. RESULTS: For this period we analysed 2,765 emergency documents and identified more than 2.5% as emergency calls by cancer patients or their relatives (the majority of patients had been in the final stage of the disease). Most emergency calls occurred at times when no general practitioner was on duty and acute dyspnoea (42.7%) was the prominent diagnosis. After emergency treatment 61.8% patients had been admitted to hospital. In most settings a PCT was not involved in the treatment of palliative care patients or their relatives (92.7%). CONCLUSIONS: Our data demonstrate that care of cancer patients in the final stage of the disease is relevant in emergency medicine. These patients are in need of help based on principles of palliative care. Under these circumstances cooperation of the medical disciplines (emergency and palliative medicine) concerned seems to be necessary. This may increase the possibility for patients to stay at home for the last days of their life. Because of this we are convinced that basic knowledge of palliative care should be integrated into the German model of post-graduate training regulations for emergency care. Combining parts of the curricula (palliative and emergency medicine) it would be possible for emergency physicians to guide their treatment by the ideas and strategies of palliative care. But we are also convinced that the system of PCT should increase and become more involved in prehospital care in emergency cases of palliative care patients.

[Terminally ill tumor patients in emergency medical care]. / Der finale Tumorpatient in der notfallmedizinischen Versorgung.

We report about an emergency case of a female patient with terminal carcinoma of the ovary. On the basis of this case it becomes evident that palliative care questions are also important in emergency medicine. In this situation cooperation of the medical disciplines involved appears urgently necessary. This may allow the possibility for terminally ill patients to stay at home in the last days of life.

Instantaneous diastolic pressure-flow relationship in arterial coronary bypass grafts.

OBJECTIVE: The objective of this study was to describe the diastolic pressure-flow relationship and to assess critical occlusion pressure in arterial coronary bypass grafts in human beings. METHODS AND RESULTS: Fifteen patients were studied following elective surgical coronary artery bypass grafting. Flow in the left internal mammary artery bypass to the left anterior descending artery was measured and simultaneously, aortic pressure, coronary sinus pressure and left ventricular end-diastolic pressure were recorded. The zero-flow pressure intercept as a measure of critical occlusion pressure was extrapolated from the linear regression analysis of the instantaneous diastolic pressure-flow relationship. Mean diastolic flow was 46 +/- 17 mL min(-1), mean diastolic aortic pressure was 60.5 +/- 10.0 mmHg. Diastolic blood flow was linearly related to the respective aortic pressure in all patients (R-values 0.7-0.99). The regression lines had a mean slope of 2.1 +/- 1.2 mL min(-1) mmHg(-1). Mean critical occlusion pressure was 32.3 +/- 9.9 mmHg and exceeded mean coronary sinus pressure and mean left ventricular end-diastolic pressure by factors of 3.1 and 2.6, respectively. CONCLUSIONS: Our data demonstrate the presence of a vascular waterfall phenomenon in the coronary circulation after internal mammary artery bypass grafting. Critical occlusion pressure in arterial grafts considerably exceeds coronary sinus pressure as well as left ventricular end-diastolic pressure and should thus be used as the effective downstream pressure when calculating coronary perfusion pressure. Our data further suggest that the slope of diastolic pressure-flow relationships provides a more rational approach to assess regional coronary vascular resistance than conventional calculations of coronary vascular resistance.

[Indicators of structural quality in palliative care for cancer pain patients in Lower-Saxony]. / Palliativmedizinische Betreuung von Tumorschmerzpatienten in Niedersachsen Indikatoren der Strukturqualität.

INTRODUCTION: Palliative care in Germany fails to reach established standards. To improve this situation the Chamber of Physicians of Lower-Saxony initiated SUPPORT in 1995. Prior to interventions structural quality of care was evaluated, specifically the rate of availability of opioid-prescription-forms and the ability to treat chronic pain (defined as a construct of knowledge, attitudes and skills) were examined. METHODS: The survey was carried out using a standardized questionnaire mailed to a representative stratified sample of 1200 physicians. RESULTS: Out of 865 answering physicians (response rate 72.1%) only 36.9% had their own opioid-prescription-forms. Differentiations regarding to specialty, working place (clinic vs. private practice) and treatment of cancer pain patients during the last three months shows a better result for GPs (84.6%), internists (48.6%), gynecologists (51%) and pain specialists (66.7%). Only 33.1% of respondents claimed knowledge of the WHO-3-step-analgesic-ladder. Again the aforementioned differentiations yield somewhat better results for GPs (49.2%), internists (51.5%), gynecologists (34.7%) and pain specialists (55.6%), however only two thirds of these physicians were able to identify the correct number of steps of the WHO-algorithm. CONCLUSIONS: These results verify an insufficient structural quality in palliative care in Lower-Saxony. In the authors' opinion effective improvements can only be achieved by implementing a parallel strategy:improvement of basic knowledge in pain management with sufficient transfer of this knowledge into practice as well as raising the rate of availability of opioid-prescription-forms,and, on the other hand, establishing local palliative-care-teams with nursing and medical expertise with 24/7 on-demand availability to optimize palliative care.

[Improvement of palliative outpatient treatment of terminally ill cancer patients - SUPPORT as example - The ethically preferable alternative to euthanasia]. / Optimierung der ambulanten palliativmedizinischen Betreuung terminal kranker Tumorpatienten am Beispiel SUPPORT - ethisch zu präferierende nach aktiver Sterbehilfe.

INTRODUCTION: Industrial countries are experiencing substantial increases in cancer prevalence. While advanced cancer therapies resulted in prolonged survival most neoplasms still are incurable. Especially advanced stages of cancer are often accompanied by severe pain and other disabling symptoms. Sufficient pain and symptom control is needed to maintain a decent quality of life for cancer patients. However, expert palliative care for patients suffering from cancer pain is still insufficient. These deficits have encouraged pro-euthanasia pressure groups demanding legitimation of physician-assisted-suicide in Germany. Acting under the guise of promoting patient's autonomy these groups are gaining additional momentum from similar legislation passed in the Netherlands. METHODS: Hospice movement and specialists in palliative medicine reject euthanasia as unethical and instead push for the global development of palliative care services. To address these issues the project SUPPORT was established in the Southern part of Lower-Saxony in 1996 with approval by the local ethics committee and sponsored by the German Ministry of Health. A palliative-care-team (PCT) of nurses and physicians with expert knowledge in palliative medicine supports patients after discharge from hospital by providing state-of-the-art palliative care at home. The PCT is available as a 24/7 standby service and can be called on demand by general practitioners, members of outpatient nursing services as well as by patients and their relatives. By cooperating with the PCT these professional and lay caregivers improve their knowledge and skills regarding pain and symptom control for terminally ill patients. RESULTS: During almost 4 years of practical work more than 50 % of the patients enrolled in the project died at home compared to about 20 % under regular conditions. These data point out quite impressively that due to the PCT-interventions recurrent hospitalisations in a majority of cancer pain patients can be avoided when expert knowledge and help is available at home for patients, their relatives and caregivers whenever needed. CONCLUSION: When sufficiently supported at home by palliative experts the number of patients dying at home is reasonably higher than the rate observed under regular conditions. This would also comply with the wishes of most patients who prefer to die in the privacy of their own home. The project data suggest that the concept of SUPPORT should be capable to improve the current state of palliative medicine in other areas of Germany as well.

[Basics of drug therapy of cancer pain]. / Grundlagen der medikamentösen Tumorschmerztherapie.

Industrial countries experience a significant increase of cancer prevalence. Despite recent advances in the treatment of various types of cancer still most of the patients cannot be cured. Especially the advanced incurable stages of cancer, however, often are accompanied by severe pain. Therefore, the high demand for a sufficient pain management and symptom control seems obvious. Throughout the last decades new drugs and techniques for the management of cancer pain have been developed. Most cancer patients should experience sufficient pain-management if existing recommendations for the pharmacological treatment of cancer pain (e.g. WHO-guidelines) are followed consequently. If, nevertheless, intractable pain or ongoing disabling symptoms continue despite proper therapy, every doctor should feel himself obliged to consult an expert in palliative medicine, in order not to tolerate avoidable suffering of his patient.
