Informed consent for pediatric leukemia research: clinician perspectives

BACKGROUND

Good, fully informed consent is critical to the ethical conduct of clinical cancer research. The authors examined clinician perspectives on informed consent for pediatric research by surveying clinicians at five major medical centers that routinely enroll patients in Children's Cancer Group studies.

METHODS

Building on a pilot study, a questionnaire was designed to elicit clinicians' general opinions, approaches, and suggestions related to informed consent in pediatric leukemia trials. Questionnaires were mailed to 132 clinicians. Eighty-nine questionnaires were returned, along with 13 nonparticipant forms notifying us of the clinician's inability to participate because of a lack of experience in pediatric informed consent. The response rate was 75%.

RESULTS

Providing information so that families can decide about study entry was ranked as the most important goal of the informed consent process, whereas parents' state of shock was rated the most significant obstacle to good informed consent. Clinicians cited high levels of parental comprehension of key aspects of clinical research studies and reported information overload and increased anxiety as effects of the informed consent process on parents. Several key items were associated with clinicians' gender, race, and professional experience. Finally, one open-ended question yielded 126 suggestions for how to improve the informed consent process that were grouped into 10 meaningful categories.

CONCLUSIONS

Clinicians report a range of approaches, opinions, concerns, and suggestions for improving the informed consent process. The article proposes that their views and suggestions be integrated with those of parents and patients in attempts to survey and improve informed consent in pediatric oncology.

Impact of a guideline-based disease management team on outcomes of hospitalized patients with congestive heart failure

BACKGROUND

Congestive heart failure is the most common reason for hospitalization in the United States, and guidelines to improve the quality of care for patients with congestive heart failure have been developed. However, adherence is typically low. We hypothesized that a guideline-based care management team would result in greater quality and efficiency of care than guidelines alone.

METHODS

A faculty cardiologist and nurse care manager at an academic medical center reviewed each patient's data and made guideline-based recommendations. Hospital length of stay, total costs, and use of recommended guidelines were compared between 173 patients before team implementation but with available guidelines, 283 care-managed patients, and 126 concurrent non-care-managed patients.

RESULTS

Care-managed patients achieved higher rates of use of angiotensin-converting enzyme inhibitor than baseline or non-care-managed patients (95%, 60%, and 75%, respectively; P<.001), as well as increased adherence to guidelines for daily weight monitoring and assessment of left ventricular function. Hospital length of stay was lower (median, 3, 4, and 5 days, respectively; P<.001) as were costs of hospitalization (median, $2934, $3209, and $4830, respectively; P<.01). These differences persisted after adjustment for severity of illness.

CONCLUSIONS

When compared with dissemination of guidelines alone, an active care management approach was associated with significant improvements in quality and efficiency of care for hospitalized patients with congestive heart failure.

Design and implementation of an inpatient disease management program

OBJECTIVE

To describe the development and implementation of an inpatient disease management program.

STUDY DESIGN

Prospective observational study.

PATIENTS AND METHODS

On the basis of opportunities for improving quality or efficiency of inpatient and emergency department care, 4 diagnoses, including congestive heart failure (CHF), gastrointestinal hemorrhage, community-acquired pneumonia and sickle-cell crisis were selected for implementation of a disease management program. For each diagnosis, a task force assembled a disease management team led by a "physician champion" and nurse care manager and identified opportunities for improvement through medical literature review and interviews with caregivers. A limited number of disease-specific guidelines and corresponding interventions were selected with consensus of the team and disseminated to caregivers. Physician and nurse team leaders were actively involved in patient care to facilitate adherence to guidelines.

RESULTS

For quarter 2 to 4 of 1997, there were improvements in angiotensin-converting enzyme inhibitor use, daily weight compliance, assessment of left ventricular function, hospital costs, and length of stay for care-managed patients with CHF. Differences in utilization-related outcomes persisted even after adjustment for severity of illness. For the other 3 diagnoses, the observational period was shorter (quarter 4 only), and hence preliminary data showed similar hospital costs and length of stay for care-managed and noncare-managed patients.

CONCLUSIONS

An interdisciplinary approach to inpatient disease management resulted in substantial improvements in both quality and efficiency of care for patients with CHF. Additional data are needed to determine the program's impact on outcomes of other targeted diagnoses.
