RESUMO

BACKGROUND: Little is known about the subjective experience of breast cancer survivors after primary treatment. However, these experiences are important because they shape their communication about their illness in everyday life, usage and acceptance of healthcare, and expectations of new generations of patients. The present study investigated this topic by combining qualitative and quantitative methods. METHODS: Breast cancer survivors in Bavaria, Germany were mailed a questionnaire up to seven years after enrolment into a randomised controlled clinical trial and start of their therapy. This enquired about their worst experiences during the breast cancer episode, positive aspects of the illness and any advice they would give to newly diagnosed patients. A category system for themes was systematically created and answers were categorised by two independent raters. Frequencies of key categories were then quantitatively analysed using descriptive statistics. In addition, local treating physicians gave their opinion on the response categories chosen by their patients. RESULTS: 133 (80%) of 166 eligible patients who survived up to seven years returned the questionnaire. The most prominent worst experience reported by survivors was psychological distress (i.e. anxiety, uncertainty; prevalence 38%) followed by chemotherapy (25%), and cancer diagnosis (18%). Positive aspects of the illness were reported by 48% with the most frequent including change in life priorities (50%) and social support (22%). The most frequent advice survivors gave was fighting spirit (i.e. think positive, never give up; prevalence 42%). Overall, physicians' estimates of the frequency of these responses corresponded well with survivors' answers. CONCLUSIONS: Although physicians' understanding of breast cancer patients was good, psychological distress and chemotherapy-related side effects were remembered as particularly burdensome by a substantial part of survivors. On the one hand, patients' quality of life needs to be assessed repeatedly during medical follow-up to identify such specific complaints also including specific recommendations to the physician for targeted psychosocial and medical support. On the other hand the advices and positive aspects of the disease, reported by the survivors, can be used to promote positive ways of coping with the illness.

RESUMO

BACKGROUND: In addition to their antimicrobial activity, antibiotics modulate cellular host defence. Granulocyte-colony stimulating factor (G-CSF) is also a well known immunomodulator; however little is known about the interactions of G-CSF with antibiotics. We investigated in septic rats the effects of two antibiotic combinations with G-CSF. METHODS: In two clinic modelling randomised trials (CMRTs), male Wistar rats were anesthetized, given antibiotic prophylaxis, had a laparotomy with peritoneal contamination and infection (PCI), and were randomly assigned (n = 18 rats/group) to: 1) PCI only; 2) PCI+antibiotic; and, 3) PCI+antibiotic+G-CSF prophylaxis (20 mug/kg, three times). This sequence was conducted first with 10 mg/kg coamoxiclav, and then with ceftriaxone/metronidazole (Cef/met, 10/3 mg/kg). In additional animals, the blood cell count, migration and superoxide production of PMNs, systemic TNF-alpha and liver cytokine mRNA expression levels were determined. RESULTS: Only the combination coamoxiclav plus G-CSF improved the survival rate (82 vs. 44%, p < 0.001). Improved survival with this combination was accompanied by normalised antimicrobial PMN migratory activity and superoxide production, along with normalised systemic TNF-alpha levels and a reduced expression of TNF-alpha and IL-1 in the liver. CONCLUSION: There are substantial differences in the interaction of antibiotics with G-CSF. Therefore, the selection of the antibiotic for combination with G-CSF in sepsis treatment should be guided not only by the bacteria to be eliminated, but also by the effects on antimicrobial functions of PMNs and the cytokine response.

RESUMO

BACKGROUND AND AIMS: A system for quality of life (QoL) diagnosis and therapy in breast cancer patients was developed according to the Medical Research Council (MRC) framework of complex interventions. Along MRC's five phases in the continuum of evidence, the present paper deals with phase I: modeling (i.e., delineating the conceptual, methodological, and logistic requirements). BASIC ELEMENTS: Theoretical background is a new conceptualization of QoL that provides a rational basis to diagnose "diseased" QoL. A care pathway as the central part of modeling is composed of the following interrelated structural elements: patients (n = 170), clinicians (n = 10), experts in a quality of life unit (n = 5), coordinating practitioners (n = 38), local opinion leaders (n = 12), and professional therapists for QoL enhancing therapies (n = 75). Networking of these structural elements was achieved by clinical algorithm. In the clinical center, the patient and doctor delivered a questionnaire (EORTC) and health status report. The QoL unit transformed it into a profile and experts' report. The coordinating practitioner transformed the latter into a decision on QoL therapy and the care pathway ended with the professional therapists. Implementation of this system used a multifaceted strategy including educational outreach visits, local opinion leaders, and quality circles. CONCLUSION: The suffering cancer patient is the main focus of this QoL diagnosis and therapy system. It will have to pass the rigorous test of a definitive randomized trial.

RESUMO

BACKGROUND: We aimed to improve the postoperative outcome of high-risk patients (American Society of Anesthesiologists class 3 and 4) recovering from colorectal cancer surgery by using recombinant human G-CSF (filgrastim) as perioperative prophylaxis. METHODS: In a double-blinded, placebo-controlled trial, 80 patients undergoing left-sided colorectal resection were randomized to filgrastim or placebo. Filgrastim (5 mug/kg) or placebo was administered in the afternoon on day -1, 0, and +1 relative to the operation. Primary endpoints were in a hierarchic order: quality of life (QoL) over time (determined at discharge, 2 and 6 months after operation with the European Organization for Research and Treatment of Cancer questionnaire) and the McPeek recovery score, which measures death and duration of stays in the intensive care unit and hospital. Predefined secondary endpoints were global QoL, subdomains of QoL, postoperative recovery, duration of stay, 6-month overall survival, complication rates, and cellular and immunologic parameters. RESULTS: There were no significant differences in both primary endpoints between the treatment groups. A significant improvement (P < .05) was obtained by filgrastim prophylaxis in the QoL subdomain family life /- social functioning,; thus, more patients recovered to their preoperative state (14 vs 4 with placebo) as determined by structured interviews. Duration of hospital stay (14 vs 12 days) and noninfectious complications were decreased from 8% to 3%. CONCLUSIONS: High-risk patients undergoing major operation for colorectal cancer profited from filgrastim prophylaxis with regard to duration of hospital stay, noninfectious complications, social QoL, and subjective recovery from operation. These endpoints, however, were secondary, and the primary endpoints (overall QoL and the McPeek index) did not show comparable benefits. A new confirmatory trial with the successful endpoints of this trial, as well as a cost analysis, will be needed to confirm the results before a general recommendation for the prophylactic use of G-CSF in high-risk cancer patients can be given.

RESUMO

BACKGROUND: The project conducted at the Tumour Centre in Regensburg aims to integrate quality of life (QL) diagnostics with the therapy of breast cancer patients and to evaluate the efficacy of QL diagnostics in the context of a randomized clinical trial. METHODS: The Regensburg Tumour Centre provides the infrastructure of the present project (telemedicine, project groups, quality circle). The treatment of breast cancer patients is based on the recent national breast cancer therapy guideline, including assorted QL-enhancing therapy options such as pain therapy, physiotherapy and lymphatic drainage, psychotherapy, social counselling and rehabilitation, nutrition and sports. During an implementation phase a new method of QL diagnostics has been developed. Five experts with varying professional background use the individual patient's QL profile and clinical and socio-demographic information in order to generate a QL report including a treatment recommendation. The study is designed as a two- arm randomized clinical trial with one test group (communication of the QL findings to the co-ordinating physician) and a control group (no communication). Patients with newly diagnosed breast cancer who are treated in the study region by one of the co-ordinating doctors will be included in this randomized study. At designated points in time QL assessments (EORTC QLQ-C30 plus BR23) will be conducted over a 12-months period. EXPECTED RESULTS: We expect that patients in the test group will experience a lower amount of QL deficits at the end of the study period (M = 1, SD = 2) than patients in the control group (M = 2, SD = 2). The statistical confirmation of this expected effect requires a total sample size of N = 200 (n = 100 vs. n = 100, alpha = 5% [two-tailed], beta = 10%). CONCLUSIONS: This is the first study to evaluate a new form of QL diagnostics in the complexity of a real patient care environment, and it promises to make the inclusion of the quality of life concept into the current breast cancer treatment guideline more tangible.

RESUMO

The Program for National Disease Management Guidelines (German DM-CPG Program) was established in 2002 by the German Medical Association (umbrella organization of the German Chambers of Physicians) and joined by the Association of the Scientific Medical Societies (AWMF; umbrella organization of more than 150 professional societies) and by the National Association of Statutory Health Insurance Physicians (NASHIP) in 2003. The program provides a conceptual basis for disease management, focusing on high-priority health-care topics and aiming at the implementation of best practice recommendations for prevention, acute care, rehabilitation and chronic care. It is organized by the German Agency for Quality in Medicine, a founding member of the Guidelines International Network (G-I-N). The main objective of the German DM-CPG Program is to establish consensus of the medical professions on evidence-based key recommendations covering all sectors of health-care provision and facilitating the coordination of care for the individual patient through time and across interfaces. Within the last year, DM-CPGs have been published for asthma, chronic obstructive pulmonary disease, type 2 diabetes, and coronary heart disease. In addition, experts from national patient self-help groups have been developing patient guidance based upon the recommendations for health-care providers. The article describes background, methods, and tools of the DM-CPG Program, and is the first of a publication series dealing with innovative recommendations and aspects of the program.

RESUMO

It is rather counterproductive to get caught up in never ending discussions on what quality of life (QOL) is and whether it can be assessed. This article is based on the idea that it is much more important to improve the conceptual frameworks that allow the use of the QOL concept in clinical practice. Survival of the QOL concept within the medical community will depend on its contributions to a better understanding of patients and to improving patient care. It is important to accept that QOL should not be viewed in isolation but in synopsis, with other psychologic concepts and clinical data. We propose a profile format that presents QOL data in a way that is easily accessible for clinicians, allowing action to be taken immediately. QOL profiles are never a substitute but a starting point for a patient-doctor interaction. A profile driven interaction has the potential to be structured, efficient, and leading to action.

RESUMO

BACKGROUND: Medical treatment in patient-centred care in oncology is broadly managed and regulated in terms of guideline development, cancer centres, and quality assurance by cancer registries. In contrast to this quality management cycle (PDCA), there are no equal standards for patient-reported outcomes like quality of life (QoL). Therefore, the Tumour Centre Regensburg e.V., a population-based regional cancer registry covering a population of more than 2.2 million people in the Upper Palatinate and Lower Bavaria, Germany, designed and implemented a QoL pathway. In a complex intervention with QoL diagnosis and therapy (multidimensional therapeutic network), effectiveness for patients with breast cancer has been demonstrated. To provide local tailored QoL diagnosis and therapy to other cancer patients as well, external validity needs to be extended by adapting the QoL pathway to another tumour entity. METHODS/DESIGN: The QoL pathway will be tested for colorectal cancer patients in a pragmatic randomised controlled trial. Two hundred twenty primary colorectal cancer patients, surgically treated in one of four hospitals, will be included. QoL is measured in all patients 0, 3, 6, 12, and 18 months after surgery (European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, QLQ-CR29). In the intervention group, QoL scores are transformed into a QoL profile. This is sent to the coordinating practitioner (general practitioner, internist, or oncologist) with an expert report including treatment recommendations for QoL deficits. The control group receives routine follow-up care attending the guideline recommendations for colorectal cancer without profile or expert report. At the primary endpoint (12 months), the rates of patients with diseased QoL in both groups are compared. DISCUSSION: This randomised trial is the first complex intervention investigating the effectiveness of an intervention with QoL diagnosis and tailored QoL therapy in colorectal cancer patients. The results will show if this QoL pathway improves the patients' QoL during follow-up care of their disease. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02321813 (registered December 2014).

RESUMO

Hypertension is proposed as a risk factor among others (high age, diabetes mellitus, and pre- and intraoperative bleeding) for adverse outcomes, such as severe infections, leading to sepsis and to multiple organ failure as the most deleterious complication. Hypertension was modeled with spontaneous hypertensive rats (SHR) and Dahl salt-sensitive (DS) rats and the infective complication by polymicrobial, peritoneal contamination, and infection (PCI). The concept of clinic modeling randomized trials was used to simulate clinical complexity, including a relevant antibiotic prophylaxis in combination with granulocyte-colony stimulating factor (G-CSF) and clinical trial conditions. Outcome parameters were: survival, systemic cytokines (protein), and organ-specific cytokine levels (mRNA). With low complexity (no prophylaxis), 28% of the animals in the Wistar and 50% in the SHR group survived (P=0.17). Tumor necrosis factor-alpha levels were lower in the liver of SHR vs. Wistar rats with PCI (P<0.01). The anti-inflammatory cytokine interleukin (IL)-10 was expressed on a higher level in SHR with PCI compared with Wistar rats (P<0.01). With increased complexity (antibiotic and G-CSF prophylaxis) the survival rate was increased from 50% in Wistar rats to 89% in SHR (P<0.01) and the mRNA expression of IL-6 was decreased in the kidney of SHR (P<0.05). Survival rate was 44% in the DS rats vs. 67% of the Wistar rats (P=0.18). The mRNA expression of tumor necrosis factor-alpha and IL-10 was reduced (P<0.01) by pretreatment in the liver of DS rats with PCI. The hypertensive, genetically distinct SHR and DS rats express different patterns of pro- and anti-inflammatory cytokine levels after PCI. G-CSF and antibiotic prophylaxis increases only in SHR survival and decreases IL-6 mRNA expression in the kidney significantly.

RESUMO

BACKGROUND: A previous upper-gastrointestinal bleeding trial showed that patients treated with repeated fibrin glue injection for upper-gastrointestinal bleeding have significantly less rebleeding than those treated with polidocanol. OBJECTIVE: To analyse the cost and effectiveness of repeated fibrin glue injection and to investigate whether these results change physicians' attitudes. DESIGN: A retrospective random sample of five hospitals from the previous study, collection of cost identification, and follow-up data on 320 patients (155 in the polidocanol group, 165 in the fibrin glue group). METHODS: An incremental cost-effectiveness analysis and comparison of outcomes was performed using chi-squared tests and Kaplan-Meier survival analysis. A survey was carried out using a questionnaire in the five hospitals on local guidelines for management of ulcer bleeding, and its results were analysed qualitatively. The measure of effectiveness is the number of prevented rebleedings. Further variables were length of hospital stay and length of intensive care unit (ICU) stay. RESULTS: The cost for the prevention of one additional rebleeding by repeated fibrin glue treatment amounts to 14,316 +/- 4981 euros (incremental cost-effectiveness ratio). There were no significant differences in length of stays in ICU or in hospital. The physicians did not change their management plans for patients with upper-gastrointestinal bleeding. In a survey, it was seen that other factors, such as local guidelines, attitudes towards new treatment options, and ease of handling of drugs, are more important than a result of a single study for a behavioural change of the doctors. CONCLUSIONS: The study was not designed prospectively to address a pharmacoeconomic question. As relevant variables (e.g. length of ICU stay) could not be reliably ascertained retrospectively, this may lead to biased estimates of the incremental cost-effectiveness ratio.

RESUMO

Quality of life (QoL) is an important outcome measure in clinical studies, but interpretation is hindered by incompleteness of data. We addressed this issue in a population-based cohort study of 146 patients with newly diagnosed rectal cancer. QoL was assessed by means of European Organization for the Research and Treatment of Cancer questionnaires at discharge from hospital after primary treatment and then every 3 months for 2 years. In parallel, objective clinical data were documented. Analyses were conducted in three steps: participants versus non-participants with QoL-assessment; poor compliers who filled in only one or two questionnaires (n=20) versus good compliers who filled in all or nearly all questionnaires (n=18); and the proportion of missing forms and critical (very poor) QoL scores in risk patients versus non-risk patients over the course of 2 years. Non-participants and poor compliers were older, were more likely to receive palliative (rather than curative) treatment, and had worse scores for physical status. Tumour progression and therapeutic interventions were more frequent in poor compliers than in good-compliers. Patients with risk factors (age 475 years, poor physical status, palliative treatment) were more likely to have missing questionnaires and critical QoL scores in respect of physical functioning and global quality of life over the course of 2 years. Missing values for QoL have clinical as well as methodological implications, because QoL scores can enhance a clinician's insight. Unwillingness to fill in a questionnaire is an indicator of serious illness. Studies that report sample statistics without specifying compliance rates and the characteristics of non-compliers will give a misleadingly positive picture.

RESUMO

Systematically developed, evidence- and consensus-based guidelines are important tools for improving health care services. The effectiveness of a guideline does not only relate to its methodological quality but also to the implementation strategy used. The following paper describes the systematic development of a strategy for implementing and evaluating the guideline "Early Detection of Breast Cancer in Germany" as part of a national project. A multi-faceted systematic implementation strategy has been developed addressing existing barriers and building on projects that have recently been introduced in Germany to improve the early detection and management of breast cancer. The aim is to induce behavioural changes in women as healthcare recipients and physicians as healthcare providers, both involved in the medical decision-making process within the scope of the guideline. Furthermore, it supports organisational changes to assure compliance with the guideline by means of quality assurance and quality management. To ensure evaluation of the implementation process a set of quality indicators have been identified for the baseline assessment of structures, provider performance and outcomes. Both the effectiveness of the implementation process and the effectiveness of the guideline itself will be measured by using the same set of indicators for reevaluation within a pre-defined time interval of 18 months. The quasi-experimental design of this uncontrolled before and after implementation study outlined in the present paper allows the assessment of clinically relevant changes using quality indicators that measure the effectiveness of the guideline on a national level.

RESUMO

The aim of this evidence-, consensus- and outcome-based good clinical practice guideline is to help physicians, and women in making appropriate healthcare decisions about the early detection of breast cancer. The principle of early detection of breast cancer comprises the detection and diagnosis of pre-malignant breast tumours (UICC stage 0, carcinoma in situ) with a possible cancer risk reduction and the detection and diagnosis of breast cancer at an early stage (UICC stage 1) with a scientifically proven 90% chance of cure. By establishing a nation-wide comprehensive quality assurance program for the early detection of breast cancer this guideline lays the foundation for a timely reduction of breast cancer mortality and achievement of cure with less impairment of patient's quality of life. It would appear that this guideline makes major improvements in women's healthcare feasible.

RESUMO

Utility is a concept that originates from utilitarianism, a highly influential philosophical school in the Anglo-American world. The cornerstone of utilitarianism is the principle of maximum happiness or utility. In the medical sciences, this utility approach has been adopted and developed within the field of medical decision making. On an operational level, utility is the evaluation of a health state or an outcome on a one-dimensional scale ranging from 0 (death) to 1 (perfect health). By adding the concept of expectancy, the graphic representation of both concepts in a decision tree results in the specification of expected utilities and helps to resolve complex medical decision problems. Criticism of the utility approach relates to the rational perspective on humans (which is rejected by a considerable fraction of research in psychology) and to the artificial methods used in the evaluation of utility, such as Standard Gamble or Time Trade Off. These may well be the reason why the utility approach has never been accepted in Germany. Nevertheless, innovative concepts for defining goals in health care are urgently required, as the current debate in Germany on "Nutzen" (interestingly translated as 'benefit' instead of as 'utility') and integrated outcome models indicates. It remains to be seen whether this discussion will lead to a re-evaluation of the utility approach.

RESUMO

OBJECTIVE: We evaluated the effects of a granulocyte-colony stimulating factor (G-CSF) prophylaxis in two clinically relevant situations, hemorrhage on the day before infection (e.g., trauma) and acute hemorrhage followed subsequently by infection (e.g., operative complication). A two-hit model of hemorrhage and polymicrobial peritoneal contamination and infection (PCI) was used to assess the influence of G-CSF on the outcome, bacterial clearance, and cytokine pattern. DESIGN: Clinic modeling randomized laboratory trial. SETTING: University laboratory. SUBJECTS: One hundred thirty-two male rats. INTERVENTIONS: In trial 1 we compared a) preoperative PCI only; b) preoperative hemorrhage plus PCI; and c) hemorrhage plus PCI plus G-CSF prophylaxis (n=18 rats/group). In trial 2, intraoperative hemorrhage was assessed with the same trial design. Primary end point was survival at 120 hrs. In trial 2 additionally, six rats per group and six naive control rats were used for secondary end point analysis. MEASUREMENTS AND MAIN RESULTS: Primary end point was mortality at 120 hrs. Secondary end points were granulocyte counts, bacterial clearance, and local cytokine levels. In trial 1 survival rate was 56% after PCI only, 17% after hemorrhage plus PCI, and 61% after hemorrhage plus PCI plus G-CSF (p<.01). In trial 2 survival rate was 33% after PCI only, 17% after hemorrhage plus PCI, and 50% after hemorrhage plus PCI plus G-CSF (p<.05). In trial 2, neutrophil counts were doubled to 66% 1 hr after hemorrhage (p<.05), colony-forming units of microbes in the lung and liver were halved to 166+/-56 and 134+/-28 colony-forming units (p<.05 for liver), and the macrophage inflammatory protein-2 expression in the lung was halved to 0.88+/-0.06 pg of complementary DNA (p<.05) by G-CSF prophylaxis compared with hemorrhage and PCI. CONCLUSIONS: Hemorrhage (first hit) sensitized the host for a second hit of polymicrobial PCI independent of the timing. G-CSF prophylaxis improved survival and clearance of microbes and reduced the proinflammatory chemokine macrophage inflammatory protein-2 in the lung.

RESUMO

OBJECTIVES: Improvements in the life expectancy of women with breast cancer raise important questions how to improve quality of life (QoL) for women sustaining complications and side effects of cancer treatment. The presented study examined the prevalence of arm morbidity in a cohort of primary breast cancer patients over time as a result of the extent of axillary lymph node dissection. Of particular interest is the question of using a recognized QoL assessment instrument at defined assessment points as an endpoint criteria of oncological treatment. METHODS: A prospective, population-based, longitudinal cohort study of patients with primary breast cancer was performed (n = 389). QoL data (EORTC QLQ C30 + BR23) and clinical data were assessed at designated time points. Primary endpoint of this analysis was patient reported arm morbidity assessed with the three-idem scale in the BR 23 (swelling, moving, pain). RESULTS: 20% of the patients evidenced considerable impairments in arm functioning. Arm morbidity was significantly related to the number of lymph nodes dissected (P < 0.002 entire cohort, P < 0.001 lymph node negatives) and was independent of age, stage of the disease, kind of breast surgery and radiation treatment. Early impairments in arm functioning (below 50 score values) assessed within 6 months after axillary surgery was a good predictor for late arm morbidity at 12 months RR 11.5 (CI 95% 4.7-28.4), 24 months RR 6.0 (CI95% 2.8-13.3) and 36 months RR 3.8 (CI 95% 1.8-7.9). CONCLUSIONS: Arm morbidity after axillary surgery is a severe and chronic condition affecting many breast cancer patients. The recognized QoL assessment instrument depict patients with severe impairments in arm functioning after axillary lymph node dissection and predict late arm morbidity. To increase patients' quality of life it thus may serve as a valid assessment tool for screening, allowing early referral for treatment and monitoring.
