Critical Care: Where’s the Evidence for Central Venous Pressure Monitoring?

Editor’s note: This post is by Anne Dabrow Woods, MSN, RN, CRNP, who is AJN‘s publisher and chief nurse and publisher of Wolters Kluwer Health Medical Research. It was originally published on the blog of Lippincott’s Evidence-Based Practice Network.

I read with interest the article “Central Venous Pressure Monitoring: Where’s the Evidence?” (purchase required for nonsubscribers) in the January issue of AJN. It’s part of a series called Critical Analysis, Critical Care, which will appraise the evidence regarding common critical care practices. So much of what we do in nursing is not based on evidence but on how we have always done things in practice—or on research that was not credible.

This article looks at the evidence supporting the use of central venous pressure (CVP) monitoring alone to guide treatment decisions for patients. According to the article, a 2008 systematic review by Marik and colleagues concluded that CVP is not an accurate indicator of intravascular volume, nor is it an accurate predictor of fluid responsiveness (whether a patient will respond to a fluid bolus with an increase in stroke volume). The authors of the AJN article critically appraised the evidence and determined the following:

Diabetes Plus Marijuana Plus Medical Errors Minus Nursing Blogs

What’s new in health care news this week?

Diabetes everywhere. There’s an entire Health Affairs issue devoted to the topic of “Confronting the Growing Diabetes Crisis.” It looks at many interrelated issues, such as the personal financial burden of having diabetes over the course of a lifetime, whether it’s best to put scarce health care resources into focusing on prevention or treatment, models for community-based lifestyle programs for those with type 2 diabetes, the positive effects of the Affordable Care Act on giving those with diabetes access to affordable health insurance and crucial care, genetic factors related to type 2 diabetes, and a great deal more. Inevitably, many of the articles focus on type 2 diabetes, which is so closely linked to America’s obesity epidemic.

Joint studies. SmokeCartel reported this week on a large government study showing that, whatever one believes about marijuana’s psychological effects or the efficacy of its various medical uses, long-term marijuana smoking—at least one joint per day, every day of the year—does not impair lung function or contribute to the development of COPD. Will this change anyone’s mind about whether this drug is evil, a panacea for all ills, or somewhere in between? Probably not.

Unreported harm. The Office of the Inspector General (OIG) of the U.S. Department of Health and Human Services issued a report last week stating that only 14% of medical errors and other events that harm Medicare patients were reported by hospital employees. The report calls for improving reporting systems and the […]

Nurses Know

It happened back in 1976, but I still remember the sound of the distant ambulance. Why was I lying in the grass and the weeds? Hadn’t I been in the car, driving home from the Visiting Nurse Association along the country road?

So begins the January Reflections essay, “Nurses Know.” By Lois Gerber, it’s one patient’s vivid story of the many crucial roles that nurses played in her care—and it’s free, so have a look and let us know what you think. For those of you who write or who think you have a strong story to tell about nurses, nursing, or some aspect of health care, Reflections submission guidelines can be found here.—JM, senior editor/blog editor

Health Technology Hazards: Top 10 for 2012

Advances in health technology can save patients’ lives, but can also cause harm, as the recent Ecri Institute report, Top 10 Technology Hazards for 2012, reminds us. Here’s a snapshot of the hazards nurses should be focusing on, and some suggestions they give on how to prevent them.

1. Alarm hazards
The risk: With nurses being constantly bombarded by bells, it’s easy to see how alarm fatigue can set in, leading to desensitization, nurses being unable to distinguish the urgency level of alarms, and improper alarm adjusting.

Some suggestions: According to the report, a facility should look at the big picture, examining the entire alarm environment when setting up an alarm-management system. Alarm notification and response protocols should be developed to ensure that each alarm will be recognized, that the appropriate caregiver will be notified, and that the alarm will be promptly addressed. Policies should also be established to control alarm silencing, modification, and disabling.

2. Radiation exposure
The risk: High levels of radiation used during radiation therapy can cause serious harm if errors occur, including damage to normal tissue and organs. And despite radiation levels being lower in diagnostic settings, the increasing number of patients undergoing diagnostic radiography may reveal more risks in the future.

Some suggestions: The report suggests that adequate […]

Second Chances

By Marcy Phipps, RN, a regular contributor to this blog. Her essay, “The Soul on the Head of a Pin,” was published in the May 2010 issue of AJN.

I first met Ella (name and some details have been changed) when she was my patient in the intensive care unit. She’d been riding in a car she wasn’t supposed to be riding in, heading to a party she wasn’t supposed to be going to, high on drugs and not wearing a seatbelt when she was involved in a high-speed crash that left her with broken bones and internal injuries. She was in the ICU for more than a month.

Her situation wasn’t that remarkable. Ella could easily represent a common category of ICU admissions—the young adult who is often described by her parents as a “good girl,” yet who lives wildly, fearless and flip, taking risks as if consequences will never apply. I feel particularly protective of these patients, mostly because I relate to them, on some level. I remember the sense of invincibility that came with youth, and when I’m caring for these girls I often marvel at consequences I avoided in my own life. I shake my head at my younger self, alternating between […]
