A New Drug for the New Year (Jan-04)

Out with the old drugs and in with the new! How is your doctor prescribing for you?

Imagine that you are a physician and your patient is a 55-year-old white male with high blood pressure. He has no other medical problems, is on no medications, and has completed a 1-year program of diet and exercise to control his condition, but his blood pressure remains elevated at 170/105 (140/90 is the definition of high blood pressure).

As his physician, you have to decide on a medication to prescribe him in order to lower his blood pressure. You have the following options to choose from:

Diuretics: Diuretics are medications that lower blood pressure by getting rid of excess fluid in your body, making it easier for your heart to pump. They were first introduced in the 1950s.

Beta-blockers: Beta-blockers are medications that lower blood pressure by helping the heart to relax and pump more effectively, and by also reducing heart rate. They were first introduced in the 1960s.

ACE inhibitors: Angiotensin converting enzyme (ACE) inhibitors are medications that lower blood pressure by widening blood vessels and increasing blood flow. They were first introduced in 1981.

Calcium channel blockers: Calcium channel blockers are medications that lower blood pressure by relaxing blood vessels, reducing the heart's workload, and increasing the amount of blood and oxygen that reach the heart. They were also first introduced in 1981.
 
What type of medication would you prescribe this patient?
 
  • A diuretic
  • A beta-blocker
  • An ACE inhibitor
  • A calcium channel blocker

How do you compare to the physicians surveyed?

Of the physicians surveyed, 18% chose the same medication as you did. 38% chose an ACE inhibitor, 29% chose a beta-blocker, and 11% chose a calcium channel blocker. Most physicians chose an ACE inhibitor, a newer type of medication, rather than beta-blockers or diuretics, which are older types of medication.

Why is this important? When asked how they made their decision, the majority of physicians believed that diuretics were less effective and that beta-blockers were less likely to be tolerated by a patient's body than the other medications. However, a number of important studies have shown that beta-blockers and diuretics are as effective at lowering blood pressure as newer medications like ACE inhibitors and calcium channel blockers. Studies have also shown that beta-blockers and diuretics are equally or even better tolerated than the newer types of medications. Yet, the use of beta-blockers and diuretics has declined steadily in the past 15 years in favor of the newer and more expensive types of medications.

Why do physicians believe these things when the studies say otherwise?

The answer to this question is not fully known. One possibility is that physicians may be prescribing newer medications because these are the medications actively promoted by pharmaceutical companies. By providing free samples of the newer medications for physicians to give to patients, these companies may be influencing which medications physicians actually decide to prescribe. To test this possibility, after physicians had decided between diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers, they were asked if they ever provide their patients with free medication samples from these companies to treat their high blood pressure. It was found that physicians who used free samples were more likely to believe that ACE inhibitors are more effective. This isn't proof that physicians are influenced by pharmaceutical companies when prescribing medication for high blood pressure, but it does urge us to seriously consider if physicians may need to be re-educated about the effectiveness and tolerability of beta-blockers and diuretics.

Give or take a few years (Feb-05)

A longer life may result from the amount of social support present in your life, but is the longevity due to giving or receiving that support?

Imagine that in your busy schedule each week, you typically at least have Wednesday and Saturday nights free as time to spend however you want. Recently, however, one of your close friends had her car break down and now she is wondering whether you would be willing to drive her to and from a yoga class on Wednesday nights for the next three weeks while the car is in the shop. She told you that the class is only about a 15 minute drive each way. She said that you shouldn't feel pressured, and she just thought she'd ask if you had the time to help her out.

Would you be willing to drive your friend to and from her yoga class for the next three weeks?
  • Yes, I'd take the time to help her out.
  • No, I'd keep my Wednesday nights free.
Do you think that helping out others could at all affect your health?
  • Yes
  • No

Giving vs. receiving: effects on mortality

A research team of investigators at the U of M Institute for Social Research teamed up with CBDSM investigator, Dylan Smith, to conduct a study investigating whether giving or receiving help affects longevity. The researchers noted that receiving social support is likely to be correlated with other aspects of close relationships, including the extent to which individuals give to one another. Based on this, they hypothesized that some of the benefits of social contact, sometimes attributed to receiving support from others, may instead be due to the act of giving support to others.

Using a sample of 423 married couples from the Detroit area, the investigators conducted face-to-face interviews over an 11-month period. The interviews assessed the amount of instrumental support respondents had given to and received from neighbors, friends, and relatives, as well as the amount of emotional support they had given to and received from their spouse. Instrumental support included things like helping with transportation, errands, and child care, whereas emotional support involved having open discussions with a spouse and feeling emotionally supported. Mortality was monitored over a 5-year period by checking daily obituaries and monthly death record tapes provided by the State of Michigan. To control for the possibility that any beneficial effects of giving support are due to a type of mental or physical robustness that underlies both giving and mortality risk, the investigators also measured a variety of demographic, health, and individual difference variables, including social contact and dependence on the spouse.

The investigators found that those who reported giving support to others had a reduced risk of mortality. This was true for both instrumental supoprt given to neighbors, friends, and relatives, and for emotional support given to a spouse. They also found that the relationship between receiving social support and mortality depended on other factors. Specifically, receiving emotional support appeared to reduce the risk of mortality when dependence on spouse, but not giving emotional support, was controlled. Receiving instrumental support from others actually increased the risk of mortality when giving support, but not dependence on spouse, was controlled.

What can we make of these findings?

It appears from these results that the benefits of social contact are mostly associated with giving rather than receiving. Measures that assess receiving alone may be imprecise, producing different results as a function of dependence and giving support.

Given the correlational nature of this study, it is not possible to determine conclusively that giving support accounts for the social benefit traditionally associated with receiving support. Nevertheless, the results of the present study should be considered a strong argument for the inclusion of measures of giving support in future studies of social support, and perhaps more importantly, researchers should be cautious of assuming that the benefits of social contact reside in receiving support.

It's true that when helping others out, you might have to give up some of your own time, but based on the above findings, it looks like in the long run you may end up ultimately gaining more time.

Natalie Bartnik, MPH, Research Associate, HBHE Genetics Research Group, UM School of Public Health: "Why, how and when oncologists disclose genome sequencing results in clinical practice"

Abstract: Integrating an individual’s clinical history with genome sequencing data can inform diagnostic and treatment strategies tailored to the patient’s mutational landscape. In oncology, precision medicine offers the additional opportunity to characterize novel gene targets for patients with cancer who lack known or viable targets. It is not known whether oncologists communicate sequencing results to patients, or how and why oncologists integrate sequencing profiles into clinical practice. In a survey of 43 oncologists who referred 111 patients to the MIONCOSEQ Study, we found that nearly a quarter of oncologists planned to make changes to their patient’s treatment based on genomic findings. Prominent barriers to the integration of sequencing results into clinical practice were a lack of findings with perceived clinical significance, as well as limitations in locally available clinical trials. The majority of physicians planned to communicate sequencing results to their patients, mostly via in-person clinic visits.


Michele Gornick, PhD, MICHR PTSP Postdoctoral Fellow, VA HSRD Fellow & CBSSM Research Investigator: "Information and deliberation make a difference: The public’s preferences for the return of secondary genomic findings"

Abstract: As genome sequencing becomes a part of clinical practice, how best to disclose sequencing results –including secondary findings-- raises significant issues. Expert consensus panels have been convened to provide recommendations, but what do members of the public want? In order to address this gap, we organized a deliberative democracy (DD) session to educate members of the public on genome sequencing, to engage them in dialogue about the benefits and risks of the clinical implementation of this technology, and to elicit their informed perspectives about policies governing the return of secondary findings. A significant shift in participants’ perspectives on the disclosure of adult onset conditions from the baseline survey, that remained stable after a month follow-up (response rate = 87%; Χ2(1, N=60) = 4.26, p =0.039), suggests the value of education and deliberation for the appreciation of the scientific and ethical complexities of genome sequencing.


Aaron Scherer, PhD, CBSSM Postdoctoral Fellow: "Elephants, Donkeys, and Medicine: Political Differences in Health Risk Perceptions and Adherence to Medical Recommendations"

The relationship between political ideology and health is often relegated to discussions of health care policy. But what if political ideology affects much more than health care policy preferences? I will discuss two studies that provide some initial evidence that political ideology influences our perceptions of health risks and adherence to medical recommendations. In one study examining risk communication strategies, political ideology was related to differences in perceptions of Ebola and influenza risk, as well as willingness to vaccinate against these two infectious diseases. In a second study examining beliefs in medical conspiracies, political ideology was related to differences in self-reported adherence to doctor’s recommendations and prescription use. The psychological differences between conservatives and liberals that may help illuminate why these differences exist will be discussed.

Stephanie Kukora, MD and Nathan Gollehon, MD, Fellows, Division of Neonatal-Perinatal Medicine, Department of Pediatrics, UM Mott Children’s Hospital: "Epidemiology of outpatient prenatal consultation: implications for decision-making and perinatal outcomes"

Abstract: Neonatologists provide anticipatory guidance and support decision-making for complicated pregnancies, in which poor/ambiguous prognostication can lead to over-/under-treatment.  Referral to antenatal palliative care consultation (PCC) is not standard; little is known about the basis for referral, and their role in perinatal decision-making.

117 women had outpatient neonatology consultation, with decision-making for 146 fetuses with multiple anomalies/genetic, single major anomaly, or obstetric complications. 18(12%) were given a prognosis of uniform non-survival and 41(28%) had anticipated survival with intervention. Remaining fetuses were given unknown prognoses 87(60%), some qualified “likely survivable” 17(12%) or “likely poor” 33(23%). Most prognoses aligned with outcomes, though outcomes were better than predicted in 3(2%) infants and worse in 10(7%).  Mismatches between prognosis and decision occurred in 10(7%) infants who were provided resuscitation despite “non-survival” or “likely poor” prognoses.

23 (19.7%) of the 117 mother/fetus pairs received antenatal PCC.  Prognoses included: 11(48%) non-survivable, 11(48%) unknown but likely poor, 1(4%) survivable with surgical intervention. Fetal/neonatal outcome included: fetal demise 5(22%), in-hospital death 16(70%), survival to discharge 2(9%). 22 maternal/fetal pairs with 3(13%) non-survivable and 19(86%) likely poor prognoses were not referred, but had similar outcomes: fetal demise 4(18%), in-hospital death 15(68%), survival to discharge 3(14%). Those with PCC were more likely to choose comfort-care than those without (61% vs. 18%, p < 0.01). Of non-survivors, 94% with PCC died within 4 days while 27% without PCC received >14 days of intensive care.

We identified relatively few cases of mismatch between prognosis and outcome; however, rare cases of prognostic failure warrant caution. Although allowing parents to pursue aggressive neonatal care respects autonomy, it may delay rather than prevent death. Long-term outcomes with and without PCC were similar for infants with poor prognoses, though non-survivors with PCC were more likely to have a comfort care plan and shorter time to in-hospital death.


Minnie Bluhm, PhD, MPH, Assistant Professor, School of Health Sciences, Eastern Michigan University: "Oncologists' decisions about administering late chemotherapy: What makes it so difficult?"

Abstract: Background. An estimated 20-50% of incurable cancer patients receive chemotherapy in the last 30 days of life, although little data support this practice.  Continued use of chemotherapy typically precludes hospice enrollment.  It may also result in more symptoms, increased use of aggressive treatments, and worsening quality of life.  Despite this, few studies have explored oncologists' rationales for administering chemotherapy during the last weeks of life.  The purpose of this study is to examine factors that oncologists report influence their decisions about late chemotherapy.

Methods. In-depth individual interviews were conducted with 17 oncologists using a semi-structured interview guide.  Interviews were audio-recorded and transcribed verbatim.  Transcripts were coded and content analyzed for themes and patterns.

Results.  Three key findings emerged.  1) Clinical factors drive oncologists’ late chemotherapy decisions when they point to clear treatment choices, along with patient preferences.  When clinical factors are ambiguous, non-clinical factors become more salient.  2) Late chemotherapy is patient-driven.  It is used to palliate physical and emotional symptoms and maintain patient hope, even when physical benefit is not expected.  3) Caring for dying patients is difficult and impacts oncologists and their treatment decisions.  Difficulties also cited as influences favoring treatment include: emotional exhaustion, difficulty communicating about stopping or not starting chemotherapy, overwhelming sense of responsibility for life and death, feeling badly about the limits of oncology to heal, and prognostic uncertainty.

Conclusions.  Findings reveal a nuanced understanding of why it can be so difficult for oncologists to refuse chemotherapy to patients near death.  Doing so adds to the existing burden of caring for dying patients.  Therefore, at times, oncologists prescribe chemotherapy to simply help everyone feel better, regardless of expected clinical benefits or costs.  Future work is needed on the impact of caring for dying patients on oncologists and on supportive interventions that promote optimal treatment decisions.

Danielle Czarnecki, PhD Candidate, UM Department of Sociology: "Moral Women, Immoral Technologies: How Devout Women Negotiate Maternal Desires, Religion, and Assisted Reproductive Technologies"

Abstract: Catholicism is the most restrictive world religion in its position on assisted reproductive technologies (ARTs). The opposition of the Church, combined with the widespread acceptability of ARTs in the U.S., creates a potentially profound moral dilemma for those who adhere to Church doctrine. Drawing on interviews from 33 Catholic women, this study shows that devout women have different understandings of these technologies than non or less religious women. These differences are rooted in devout women’s position of navigating two contradictory cultural schemas (Sewell 1992) —“religious” and “secular”—regarding the meaning of reproductive technologies in the contemporary U.S. Religious schemas provide devout women with different cultural resources that allow them to develop strategies to avoid the use of ARTs. Yet they must still reckon with the ideal of biological parenthood. I show how devout women draw on religious doctrine to find value and meaning in their suffering , to move beyond biological motherhood,  and to ultimately achieve a moral femininity. While religion increases the burden of reproduction for devout women, it also provides the cultural resources to resist the financial, emotional, and physical difficulties experienced by women who use ARTs.


Uchenna Ezeibe, MD, Resident Physician, UMHS Department of Pediatrics & Communicable Diseases: "Pediatric Ethics Consultation Service at a Tertiary Hospital: A Retrospective Review"

Abstract: Background: Published data about hospital ethics consultation services focus primarily on adult patients. There is little information on pediatric ethics consultations – specifically whether patient demographics were related to type and prevalence of consults.

Objective: To review recent ethics consults at a large children’s hospital and explore associations with patient demographics.

Design/Methods: We reviewed ethics consults between 7/1/2009 – 12/31/2013 at a Midwest children’s hospital. We used Armstrong Clinical Ethics Coding System 2013©, modified for pediatrics, to code consults. We collected data on patient race, age, and insurance status (private vs. public) as a proxy for socioeconomic status. We used Microsoft Excel 2013© to generate descriptive statistics.

Results:, approximately 321,713 inpatient visits, and 29 ethics consults were reviewed. Most consults (72.5%) concerned inpatients. Of these, 82% originated from 1 of 3 ICUs (neonatal, pediatric, and pediatric-cardiothoracic). The most common reasons for consultation were: 1) treatment-based decision-making (31%),); 2) end-of-life decisions (28%); & 3) substitute decision-making (24%).  The mean patient age for treatment-based and substitute decision-making consults were similar at 6.8 and 7.9 years, respectively.  Younger patients (mean age: 2.4 years) were involved in end-of-life dilemmas. Patients receiving consults differed from the general patient population in that fewer patients with consults were White (52% vs. 71%) and more were  African-American (34.5% vs 9%).  Approximately 76% of patients with ethics consults had public insurance compared to approximately 29% amongst all inpatient admissions.

Conclusion:  In this single-center retrospective review, we found that African-Americans and patients with public insurance were over-represented in receipt of ethics consultations compared to the general patient population. We also found that dilemmas about end-of-life decisions were more common for younger children. Given our small numbers, strong conclusions cannot be drawn from this data. Nevertheless, our findings do point to areas where communication between family and medical team can be improved.
 

Medical Students

Systematizing the Teaching of Medical Ethics in the Undergraduate Medical Years

Medical students at the University of Michigan encounter ethical issues throughout their four years of training.  Some are obvious – decisions at the end of life, the allocation of scarce of medical resources, challenges to patient autonomy – others are less obvious – relationships between medical residents and medical students, problems with the “hidden curriculum,” and systemic discrimination in the provision of care.  Our goal is to make students aware of the variety of ethical problems in medical care and to equip them to respond to these problems in a wise and responsible manner.

To that end, our curriculum efforts focus on extending the existing curriculum and on making the medical ethics curriculum for undergraduate medical students at UM more systematic and explicit. Because we want students to become well-versed in thinking through ethical dilemmas before they encounter them in their clinical work we weave ethics into the curriculum throughout the 4 years of their undergraduate training. We use the expertise of our CBSSM faculty to create novel curricular components that incorporate our empirical work in bioethics with our particular expertise in decision science.

Increasing Opportunities for Ethics Teaching in the Clerkship Years

Discussions During Required Clinical Rotations

We facilitate regular ethics discussions for medical students at the end of their required clinical rotations in Obstetrics and Gynecology (in the third year) and Emergency Medicine (in the fourth year). To facilitate these discussions, students prepare short essays on ethical dilemmas encountered in these clerkships.  Students are given a summary of all the issues that came up that rotation, which is used as a starting point for a discussion facilitated by a clinical faculty member trained in ethics. In addition, the Internal Medicine subinternship (an option for fourth year students) includes an ethics discussion at the end of the rotation.

These discussions allow medical students to bring up concerns with ethical dilemmas in a safe environment, teach the students about approaches to ethics, and embed training in ethical decision-making in clinical practice. This is often the first time students learn about the role of the hospital ethics committee and how they can contact them if desired.

     “That was unexpectedly awesome!"

Advanced Medical Therapeutics Ethics Module

All fourth year medical students are required to take an online Advanced Medical Therapeutics course. As part of the course, we created an ethics module that includes multiple cases that present ethical dilemmas.  Each case includes pre-recorded videos of faculty discussing the ethical aspects of the case and interactive components requiring students to choose possible solutions to the problem, after which they receive explanations of the pros and cons of their choice.

Medical Ethics Path of Excellence

CBSSM faculty work closely with the medical school to strengthen the medical ethics curriculum for Michigan medical students.  Our goal is to make students aware of the broad range of  ethical challenges facing 21st century medicine – challenges in clinical care, medical research and the design of health care delivery. Most recently, a team of CBSSM faculty developed the Medical Ethics Pathway of Excellence, an opportunity for students to receive mentored training in ethics throughout their four years of medical school.

Overview of Medical Ethics Pathway to Excellence:

  • Introduced in September 2013, the first 10 students were accepted in 2014. Twelve students joined in 2015.
  • Students apply to the Ethics Path of Excellence at the end of February during their M1 year, and continue their studies through their M4 year. Students in the POE learn to:
    • Identify ethical issues in the organization and delivery of health care
    • Implement tools and strategies to address ethical issues
    • Continue their professional education and development of the skills required for leadership
  • Highlights:
    • Before applying to the Ethics Path of Excellence, students have the opportunity to attend fourteen interactive lunchtime lectures that review various aspects of ethics in a healthcare setting. Applicants must attend a minimum of five of these lectures.
    • Students who want to serve on ethics committees and/or include ethics as part of an academic career are provided with specialized training.
    • All students participate in an individualized, independent study, culminating in a capstone project in the M4 year. Often this work includes field work at CBSSM.

Beginning in 2015, the Path of Excellence has been responsible for administering the core ethics curriculum for all of the M1 students. The Ethics Path of Excellence will continue to be a co-curricular activity until 2017 when all students will be required to choose one of the paths offered in the medical school.

“We really want to educate people to be the ethics committee consultants of the future. I think it's pretty unique to have the option of pursuing this extracurricular program because essentially it teaches you leadership skills and how to be a self-directed learner. These are skills you'll really need when you become faculty. Students can take their interest in ethics and pursue it further.”             
Lauren Smith, M.D., Associate Professor of Pathology

Lauren Smith is the Director of the Path of Excellence. Andrew Barnosky, Christian Vercler, Ed Goldman, Kathryn Moseley, Janice Firn, Sacha Montas, and Raymond De Vries are core faculty members.

Start Seeing Ethics Lunch Discussions

As part of the Medical Ethics Path of Excellence, we offer lunch time discussions of cutting-edge topics in ethics. The content of these discussions includes topics such as conscientious objection, mandatory vs. optional vaccinations, patient centered care and shared decision making.  We have also used these discussions to hold mock ethics committee meetings with discussion of a specific case. Facilitators provide a relaxed atmosphere in which students can feel comfortable asking questions and voicing opinions.

 

"It is exciting to see medical students engage with the ethical issues that arise in the clinic and the classroom.  With encouragement from us they are beginning to see that there is more to medical ethics than just the well-known issues at the beginning and end of life.  While these ethical issues are important, there are also moral consequences associated with the mundane aspects of being a student and working with patients." Raymond De Vries, PhD, Director, Ethics Education Initiative
