How to

How To Craft A Clinical Practice Guideline

Leave a comment

All US trauma centers verified by the American College of Surgeons are required to have clinical practice guidelines (CPG). Trauma centers around the world generally have them, but may not be required to by their designating authority. But don’t confuse a policy about clinical management, say for head injury, with a real CPG. Policies are generally broad statements about how you (are supposed to) do things, whereas a CPG is a specific set of rules you use when managing a specific patient problem.

  1. Look around; don’t reinvent the wheel! This is the first mistake nearly every center makes. It seems like most want to spend hours and hours combing through the literature, trying to synthesize it and come up with a CPG from scratch. Guess what? Hundreds of other centers have already done this! And many have posted theirs online for all to see and learn from. Take advantage of their generosity. Look at several. Find the one that comes closest to meeting your needs. Then “borrow” it.
  2. Review the newest literature. Any existing CPG should have been created using the most up to date literature at the time. But that could have been several years ago. Look for anything new (and significant) that may require a few tweaks to the existing CPG.
  3. Create your draft, customizing it to your hospital. Doing things exactly the same as another center doesn’t always make sense, and it may not be possible. Tweak the protocols to match your resources and local standards of care. But don’t stray too far off of what the literature tells you is right.
  4. Make sure it is actionable. It should not be a literature summary, or a bunch of wishy-washy statements saying you could do this or consider doing that. Your CPG should spell out exactly what to do and when. (see examples below)
  5. Create a concise flow diagram. The fewer boxes the better. This needs to be easy to follow and simple to understand. It must fit on one page!
  6. Get buy-in from all services involved. Don’t try to implement your CPG by fiat. Use your draft as a launching pad. Let everyone who will be involved with it have their say, and be prepared to make some minor modifications to get buy-in from as many people as possible.
  7. Educate everybody! Start a campaign to explain the rationale and details of your CPG to everyone: physicians, nurses, techs, etc. Give educational presentations. You don’t want the eventual implementation to surprise anyone. Your colleagues don’t like surprises and will be less likely to follow along.
  8. Roll it out. Create processes and a timeline to roll it out. Give everyone several months to get used to it.
  9. Now monitor it! It makes no sense to implement something that no one follows. Create a monitoring system using your PI program. Include it in your reports or dashboards so providers can see how they are doing. And if you really want participation, let providers see how they are doing compared to their colleagues. Everyone wants to be the top dog.

Retained Hemothorax Part 4: The Practice Guideline

Leave a comment

Over the last three days, I reviewed some data on lytics at the request of some of my readers. Then I looked at a paper describing one institution’s experience dealing with retained hemothorax, including the use of VATS. But there really isn’t much out there on how to roll all this together.

Until now. The trauma group at Vanderbilt has a paper in press describing their experience with a home-grown practice guideline for managing retained hemothorax.  Here’s what it looks like:

I know it’s small, so just click it to download a pdf copy. I’ve simplified the flow a little as well.

All stable patients with hemothorax admitted to the trauma service were included over a 2.5 year period. The practice guideline was implemented midway through this study period. Before implementation, patients were treated at the discretion of the surgeon. Afterwards, the practice guideline was followed.

Here are the factoids:

  • There were an equal number of patients pre- and post-guideline implementation (326 vs 316)
  • An equal proportion of each group required an initial intervention, generally a chest tube (69% vs 65%)
  • The number of patients requiring an additional intervention (chest tube, VATS, lytics, etc) decreased significantly from 15% to 9%
  • Empyema rate was unchanged at 2.5%
  • Use of VATS decreased significantly from 8% to 3%
  • Use of catheter guided drainage increased significantly from 0.6% to 3%
  • Hospital length of stay was the same, ranging from 4 to 11 days (much shorter than the lytics studies!)

Bottom line: This is how design of practice guidelines is supposed to work. Identify a problem, typically a clinical issue with a large amount of provider care variability. Look at the literature. In general, find it of little help. Design a practical guideline that covers the major issues. Implement, monitor, and analyze. Tweak as necessary based on lessons learned. If you wait for the definitive study to guide you, you’ll be waiting for a long time.

This study did not significantly change outcomes like hospital stay or complications. But it did decrease the number of more invasive procedures and decreased variability of care, with the attendant benefits from both of these. It also dictates more selective (and intelligent) use of additional tubes, catheters, and lytics. 

I like this so much that I plan to adopt it at my center!

EAST Practice Management Guidelines: Elderly Falls Prevention

Leave a comment

The Eastern Association for the Surgery of Trauma (EAST) has published their most recent set of practice management guidelines. This one addresses prevention of falls in the elderly.

All trauma centers and trauma professionals are seeing more and more elderly patients, and the increase in the number of falls among these individuals is alarming. Most trauma centers are already engaging in some kind of prevention activity. However, their falls prevention efforts are all over the map, and there has been little guidance regarding what works and what does not.

So what can be done? The EAST practice management guideline group performed a methodical sweep of the literature to try to give us some objective information to shape prevention efforts. They addressed six specific questions. I have listed them below, with comments on what the literature shows us about the answers.

Question 1: Should bone mineral-enhancing agents be used? Conditional recommendation. A meta-analysis suggests that giving Vitamin D and calcium supplements tends to decrease fall-related injuries. The optimal dosing was not clear, but cholecalciferol doses of 400-800 IU daily and calcium dosing of 1000 to 1500 mg/day were most commonly used. There was a trend toward improved muscle strength and balance.

Question 2: Should hip protectors be used? Conditional recommendation. 
The evidence does show that wearing protectors decreases fall-related injury. However, compliance is usually an issue because they don’t look very cool. See below:

Question 3: Should exercise programs be used? Conditional recommendation. The literature on exercise routines shows a tremendous amount of variability in terms of the specific routines used. However, most studies do demonstrate a reduction in injury with implementation of an exercise program.

Question 4: Should physical environment modifications be made? Conditional recommendation. Conditions in the household are one of the biggest factors for causing falls. Clutter, throw rugs, poorly placed furniture all increase the risk of injury. The literature is extremely variable in the methods or equipment used, so the results are quite variable as well. Overall, home modifications such as grab bar placement, clutter removal, etc. appear to be of benefit.

Question 5: Should risk factor screening be used? Conditionally recommended. Screening for risk factors is not a specific intervention. However, it can and should be used to identify at-risk patients and direct interventions toward specific risk factors (see next question).

Question 6: Should multiple, tailored interventions be used? Strongly recommended. Research shows that if risk factor screening is applied to individuals or larger populations, and interventions directed at the specific factors identified are implemented, very favorable results are possible.

Bottom line: The best results I have personally seen at other trauma centers have been accomplished through risk factor screening and the use of multiple targeted interventions. Many centers address a single factor, or give talks to groups of older, non-injured patients. Although these activities may make us feel good, they probably don’t have the full effect that multifactorial interventions do, as addressed in Question 6. 

Elderly falls are a huge problem (and growing). Every trauma center should work on implementing a comprehensive and multi-factorial falls reduction program. And don’t try to reinvent the wheel. Many centers are already doing this, so don’t be shy about borrowing their program components!

EAST Practice Guideline: Rectal Trauma

Leave a comment

EAST just published their newest practice management guideline, which pertains to rectal trauma. They sought to answer three questions that pertain to nondestructive penetrating trauma to the extraperitoneal rectum. 

Trauma dogma from the 80′s and 90′s mandated that these injuries undergo three things: proximal diversion, distal rectal washout, and presacral drainage. The latter two have had waning interest over the intervening years, and questions have even been raised as to whether diversion is really necessary.

Practice Guideline Committee members at EAST performed a thorough and well documented review of the existing literature to determine what we really should be doing with these injuries.

Here are the factoids:

  • Proximal diversion. The major fear that prompts surgeons to divert is the possibility of infectious complications in the area of the rectal injury itself, or death. The literature consisted of 14 papers, most of which were retrospective and observational. Although there was no difference in mortality (about 0%), the incidence of infections doubled in patients without diversion. The recommendation was that patients with these injuries receive a proximal diverting colostomy.
  • Presacral drains. Only 17 papers addressed this question, and they were of low quality with few patients. There is not enough evidence to recommend this practice. And from a logistical standpoint, I could never figure out why this should work. The drain is placed in the presacral space, adjacent to the posterior rectum. How can this do anything for an anterior injury?
  • Distal rectal washout. In the good old days, this was performed through the distal portion of the newly created colostomy. There were all kinds of fancy ways to do it, and it required converting to lithotomy position and stationing someone (hint: intern) with a bag or bucket to catch the effluent. Very messy and unpleasant. Only 13 papers addressed this practice, and could not convincingly demonstrate a benefit. Not recommended.

Some additional tips of my own:

  • Do not violate the peritoneal reflection in the pelvis while doing the laparotomy. If the injury is isolated to the distal rectum, you will create a conduit for infection in the deep pelvis. You will have a hard time repairing an injury from above, especially in the usual narrow male pelvis. Don’t look at it; just let it heal on its own.
  • Create a standard end colostomy. Surgeons argue that a loop colostomy is convenient because it may be possible to close it later without reopening the midline incision. This is not always the case, and the bridge that is necessary to keep the loop above the skin makes colostomy care very difficult. Patients frequently complain about smelly leaks.

Bottom line: EAST guidelines are helpful in figuring out what to do in certain clinical situations, but they do not provide detailed guidance. This guideline provided answers (as best they could) to just three questions about rectal trauma. They justify not doing things that most surgeons have not been doing for some time. But don’t try to talk yourself out of not doing the diverting colostomy.

Practice Guidelines And Tincture Of Time

Leave a comment

Most trauma centers have at least a few practice guidelines to help the standardize the way they manage common injuries. Solid organ injury. Elder trauma. Chest tube management. But they are all designed for use in patients who present shortly after their injury.

What about someone who presents a day or two, or more, after their injury?  That changes the picture entirely. Most guidelines have a time component built in. A TBI protocol requires a repeat head CT after a certain period of time. Solid organ injury patients may have restricted activity or frequent vital signs for a while. 

But all too often, trauma professionals treat the patient with delayed presentation exactly the same as fresh trauma. For example, a patient falls and bumps their head. They have a persistent headache, and after two days decide to visit their local ED. The CT scan shows a small amount of subarachnoid blood in the area of the impact. Your practice guidelines says to admit for observation, frequent neruo checks, and repeat head CT in 12 hours.

Or a young male playing sports took a hit to his left flank. After 3 days, he’s just tired of the pain and comes to the ED for some pain medication. CT scan shows a grade III spleen injury with a small amount of hemoperitoneum. Your protocol says to admit, make NPO, liimit activity, and observe for 2 days.

What would I do in these cases? Think about it! If the patients had presented right after the event, they would have gone through your guideline and would have been discharged already. So I would review the images, talk to the patients about their injuries, then send them home from the ED with followup. They’ve already passed!

Bottom line: Remember, practice guidelines are not etched in stone. Variances are possible, but need to be well thought out in advance. And hopefully documented in the chart to expedite the inevitable trauma performance improvement inquiry. If the requisite amount of time has gone by, and the history and exam are reasonable, the patient has already passed your protocol. Send them home.
