Ethical considerations and barriers to research in surgical palliative care

The effect of multiple recruitment contacts on response rates and patterns of missing data in a survey of bladder cancer survivors 6 months after cystectomy

PURPOSE

The Bladder Cancer Quality of Life Study collected detailed and sensitive patient-reported outcomes from bladder cancer survivors in the period after bladder removal surgery, when participation in survey research may present a burden. This paper describes the study recruitment methods and examines the response rates and patterns of missing data.

METHODS

Detailed surveys focusing on quality of life, healthcare decision-making, and healthcare expenses were mailed to patients 5-7 months after cystectomy. We conducted up to 10 follow-up recruitment calls. We analyzed survey completion rates following each contact in relation to demographic and clinical characteristics, and patterns of missing data across survey content areas.

RESULTS

The overall response rate was 71% (n = 269/379). This was consistent across patient clinical characteristics; response rates were significantly higher among patients over age 70 and significantly lower among racial and ethnic minority patients compared to non-Hispanic white patients. Each follow-up contact resulted in marginal survey completion rates of at least 10%. Rates of missing data were low across most content areas, even for potentially sensitive questions. Rates of missing data differed significantly by sex, age, and race/ethnicity.

CONCLUSIONS

Despite the effort required to participate in research, this population of cancer survivors showed willingness to share detailed information about quality of life, health care decision-making, and expenses, soon after major cancer surgery. Additional contacts were effective at increasing participation. Response patterns differed by race/ethnicity and other demographic factors. Our data collection methods show that it is feasible to gather detailed patient-reported outcomes during this challenging period.

Palliative surgery: incidence and outcomes

OBJECTIVES

To describe the goals of treatment, decision-making, incidence, and outcomes of surgical palliation in advanced cancer.

DATA SOURCES

Journal articles, research reports, state of the science papers, and clinical guidelines.

CONCLUSION

Surgical palliation is common in advanced cancer settings, and is indicated primarily in settings where the goals of treatment are focused on quality of life, symptom control, and symptom prevention. More research is needed to guide evidence-based best practices in palliative surgery.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses practicing in clinical and research settings have a responsibility to arm themselves with knowledge related to the indications and options of palliative procedures, and the impact of surgery on quality of life for patients and families facing advanced cancer.

Ethical conduct of palliative care research: enhancing communication between investigators and institutional review boards

Palliative care has faced moral and ethical challenges when conducting research involving human subjects. There are currently no resources to guide institutional review boards (IRBs) in applying standard ethical principles and terms-in a specific way-to palliative care research. Using as a case study a recently completed multisite palliative care clinical trial, this article provides guidance and recommendations for both IRBs and palliative care investigators to facilitate communication and attain the goal of conducting ethical palliative care research and protecting study participants while advancing the science. Beyond identifying current challenges faced by palliative care researchers and IRBs reviewing palliative care research, this article suggests steps that the palliative care research community can take to establish a scientifically sound, stable, productive, and well-functioning relationship between palliative care investigators and the ethical bodies that oversee their work.

Advancing the science of hospice care: Coalition of Hospices Organized to Investigate Comparative Effectiveness

PURPOSE OF REVIEW

There is very little high-quality evidence to guide clinical practice in hospice care. In the areas of medical therapy, patient-centered and family-centered outcomes, and patient safety, there are numerous high-impact questions for which answers are needed. Although randomized controlled trials are the gold standard for research, such trials are difficult, time consuming, and expensive to conduct in a hospice population. Moreover, they cannot examine the implementation of therapies in real-world settings. Therefore, there is a need for novel, complementary approaches to research in this unique population.

RECENT FINDINGS

This article describes the initial experience of the Coalition of Hospices Organized to Investigate Comparative Effectiveness (CHOICE). CHOICE is a national network of hospices that use electronic health record-based data collection procedures to answer key questions relevant to clinical care and policy. By using a rich source of existing data to conduct observational studies, CHOICE is able to overcome many of the most significant challenges of randomized controlled trials in hospice. However, this approach also created unique challenges related to governance and privacy concerns.

SUMMARY

CHOICE is a growing research network that has the potential to make a contribution to the science of palliative care in a hospice population.

Surgical palliative care: recent trends and developments

Palliation has been an essential, if not the primary, activity of surgery during much of its history. However, it has been only during the past decade that the modern principles and practices of palliative care developed in the nonsurgical specialties in the United States and abroad have been introduced to surgical institutions, widely varied practice settings, education, and research.

Review: a narrative review of the published ethical debates in palliative care research and an assessment of their adequacy to inform research governance

The quality of research, and the resulting quality of evidence available to guide palliative care, is dependent on the ethical decisions underpinning its design, conduct and report. Whilst much has been published debating the ethics of palliative care research, an assessment of the quality and synthesis of the central debates is not available. Such a review is timely to inform research governance. The methodology of this study is based on the principles of systematic reviews. Fifty-seven papers were reviewed following a thorough search, and were critically appraised for their literary quality, the knowledge on which they drew and the research standards they addressed. The debates identified address vulnerability, moral appropriateness, consent, gate-keeping and inclusion and research culture. The quality of debate and the sources of knowledge varied. The debate was rich in quality and knowledge with respect to the protection of the dignity, rights and safety of research participants, but less developed in relation to those of researchers and other staff. There is also little debate about the ethics of reporting of research and the ethics underpinning research leadership. A framework is offered that reconciles the ethical issues raised with potential methodological strategies identified from the review.

Surgical palliation: getting back to our roots

This article provides an overview of the approach to patients who may benefit from palliative care. While the article's details lend themselves to the treatment of complications secondary to advanced malignancies, the data herein can also be extrapolated to other chronic, terminal diseases. Guidelines for patient selection are discussed, using currently available outcomes data as a platform for the critical decision making process. Suggestions for a multidisciplinary team approach are offered, using the palliative triangle as the ideal model of communication and cooperation. Finally, methods for measuring success are detailed, along with proposals for how to better equip the surgeons of tomorrow with the knowledge and experience needed to tackle these difficult and intimate problems.

Ethical issues in research to improve the management of malignant bowel obstruction: challenges and recommendations

Research to improve the care of patients with malignant bowel obstruction (MBO) is urgently needed. In particular, there is an urgent need for high-quality descriptive research, including prospective cohort studies, as well as randomized controlled trials to define optimal management strategies. However, investigators and clinicians face numerous barriers in conducting high-quality research in this patient population. These barriers include lack of funding, difficulties in identifying eligible patients, and a variety of practical and methodological challenges of designing these studies. In addition, there are a variety of ethical challenges that arise in the design and conduct of studies of MBO and particularly in the conduct of clinical trials. In this article, we address four categories of ethical issues: study design, recruitment, informed consent, and Institutional Review Board review. For each, we outline salient issues and suggest recommendations for enhancing the ethics of MBO studies, including interventional trials.

The international conference on malignant bowel obstruction: a meeting of the minds to advance palliative care research

There is a dearth of well-designed clinical research focusing on palliative care in cancer patients, especially those who are near the end of life. Reasons for this include ethical dilemmas in conducting such trials, communication barriers between specialties, and unclear standards for best care practices. To ensure that patients with incurable illnesses are offered the best available care, it is essential to develop and disseminate research methodologies well suited to this population. Given the multidimensional and culture-dependent nature of the end-of-life experience, it is necessary to adopt an interdisciplinary approach to developing research methods. As a means of initiating the process of palliative clinical research methodology development, malignant bowel obstruction (MBO) was used as a model to develop a research protocol. Although many treatment options for MBO have been proposed, existing literature offers little guidance with regard to algorithms for optimal management. To this end, an international leaders in quality-of-life research, ethnocultural variability, palliative medicine, surgical oncology, gastroenterology, major consortium research, medical ethics, and patient advocacy/cancer survivors was convened in Pasadena, California, on November 12-13, 2004. Participants also represented the broad ethnic and racial perspectives required to develop culturally sensitive research methods. Consensus on methodological approaches was attained through vigorous debate. Using the conference-developed MBO model to implement trials will advance palliative care research.

Teaching Palliative Care and End-of-Life Issues: A Core Curriculum for Surgical Residents

BACKGROUND

Most surgical training programs have no curriculum to teach palliative care. Programs designed for nonsurgical specialties often do not meet the unique needs of surgeons. With 80-hour workweek limitations on in-hospital teaching, new methods are needed to efficiently teach surgical residents about these problems.

METHODS

A pilot curriculum in palliative surgical care designed for residents was presented in three 1-hour sessions. Sessions included group discussion, role-playing exercises, and instruction in advanced clinical decision making. Residents completed pretest, posttest, and 3-month follow-up surveys designed to measure the program's success.

RESULTS

Forty-seven general surgery residents from Brown University participated. Most residents (94%) had "discussed palliative care with a patient or patient's family" in the past. Initially, 57% of residents felt "comfortable speaking to patients and patients' families about end-of-life issues," whereas at posttest and at 3-month intervals, 80% and 84%, respectively, felt comfortable (P < .01). Few residents at pretest (9%) thought that they had "received adequate training in palliation during residency," but at posttest and at 3-month follow-up, 86% and 84% of residents agreed with this statement (P < .01). All residents believed that "managing end-of-life issues is a valuable skill for surgeons." Ninety-two percent of residents at 3-month follow-up "had been able to use the information learned in clinical practice."

CONCLUSIONS

With a reasonable time commitment, surgical residents are capable of learning about palliative and end-of-life care. Surgical residents think that understanding palliative care is a useful part of their training, a sentiment that is still evident 3 months later.

Bench-to-bedside review: human subjects research--are more standards needed?

There are many controversial issues surrounding ethics in study design and conduct of human subjects research. In this review we briefly touch on the origin of ethics in clinical research and how the current regulations and standards came into practice. We then discuss current controversies regarding informed consent, conflicts of interest, institutional review boards, and other relevant issues such as innovative procedures and quality improvement projects. The question of whether we need more standards is a very important yet challenging one to which there is no simple answer. We address this question by reviewing and commenting on relevant literature. We conclude that what is needed are not more standards per se, but rather refinement and uniformity of current standards, and their interpretation and application both to protect human subjects and to advance medicine.

Ethics of palliative surgery in patients with cancer

BACKGROUND

Surgery is an important palliative method for patients with advanced malignant disease. In addition to concerns related to clinical decision making, various moral challenges are encountered in palliative surgery. Some of these relate to the patients and their illness, others to the surgeons, their attitudes, skills and knowledge base.

METHOD AND RESULTS

Pertinent moral challenges are addressed and analysed with respect to prevailing perspectives in normative ethics. The vulnerability of patients with non-curable cancer calls for moral awareness. Demands regarding sensibility and precaution in this clinical setting represent substantial challenges with regard to the 'duty to help', benevolence, respect of autonomy and proper patient information. Moreover, variations in definition of palliative surgery as well as limited scientific evidence with respect to efficacy, effectiveness and efficiency pose methodological and moral problems. Therefore, a definition of palliative surgery that addresses these issues is provided.

CONCLUSION

Both surgical skill and much moral sensibility are required to improve palliative care in surgical oncology. This should be taken into account not only in clinical practice but also in education and research.
