      &lt;p&gt;SAN ANTONIO  --  Minimally invasive facet arthrodesis significantly reduced pain and improved physical function for one&lt;strong&gt; &lt;/strong&gt;year in patients with medically refractory facet arthropathy, according to data from a prospective clinical series.&lt;/p&gt;
&lt;p&gt;Most patients discontinued narcotic pain relievers, researchers reported here, and only one of 28 patients in the series had no appreciable change in pain after the noninstrumented spinal surgery.&lt;/p&gt;
&lt;p&gt;&quot;The procedure does not disrupt stabilizing ligaments or muscular structures of the posterior spine, allowing unimpeded physiotherapy for low back muscular strengthening after 16 weeks,&quot; Daniel Bennett, MD, of Integrative Treatment Centers in Denver, told attendees at the American Academy of Pain Medicine meeting.&lt;/p&gt;
&lt;p&gt;&quot;If fusion occurs, symptoms should not return, as with traditional treatment modalities, such as thermal radiofrequency neurolysis.&quot;&lt;/p&gt;
&lt;p&gt;The results have provided the foundation for a prospective, multicenter, randomized clinical trial to compare radiofrequency neurolysis and minimally invasive spine facet arthrodesis, he added.&lt;/p&gt;
&lt;p&gt;Medical management of low back pain related to facet degeneration often provides minimal pain relief and can interfere with functioning. Direct injection of anesthesia into an affected joint also leads to negligible long-term benefits, said Bennett. Radiofrequency neurolysis provides only temporary pain relief and must be repeated because of nerve regeneration.&lt;/p&gt;
&lt;p&gt;All the patients had a return of pain after previous radiofrequency neurolysis and were eligible for repeat neurolytic procedures. Affected areas were confirmed by anesthetic injection, followed by a provocatory examination.&lt;/p&gt;
&lt;p&gt;The patients underwent a standardized procedure that included a small incision at the affected area, insertion of surgical pins to stabilize the joint, use of a surgical drill to achieve joint separation, and insertion of 5-mm or 7-mm Morse tapered cortical allografts.&lt;/p&gt;
&lt;p&gt;After surgery, patients wore a rigid brace for 16 weeks, at which point they began physical therapy to strengthen back muscles.&lt;/p&gt;
&lt;p&gt;The patients received a total of 102 grafts at 51 levels, and four dislodgements (3.9%) occurred. None of the patients had a return of pain after dislodgement.&lt;/p&gt;
&lt;p&gt;&quot;Among patients who retained grafts, all showed callus formation of the posterior joint and incorporation of the cortical allograft,&quot; said Bennett.&lt;/p&gt;
&lt;p&gt;At the 52-week follow-up, the average score on a 100-point visual analog pain scale was 23, down from an average of 79 prior to the intervention. Patients&apos; scores on the Oswestry Disability Index averaged 8.32, compared with 33.46 at baseline.&lt;/p&gt;
&lt;p&gt;All but four patients discontinued narcotic medication, and the morphine dose required by those four decreased from a baseline range of 150 to 360 mg to a range of 10 to 30 mg at one year.&lt;/p&gt;

                     title="Helmets Linked to Reduced Head Injury Risk in Alpine Sports (CME/CE)"
                     score="0.008"
                     href="http://www.medpagetoday.com/Neurology/HeadTrauma/tb/18227?impressionId=1265752808103"
                     
      Skiers and snowboarders have a significantly lower risk of head injury if they wear helmets, a meta-analysis showed.&lt;br&gt;
&lt;br&gt;In a pooled analysis of nine studies, helmet wearers were 35% less likely to suffer a head injury than those without helmets (OR 0.65, 95% CI 0.55 to 0.79), Brent Hagel, PhD, of the University of Calgary in Alberta, and colleagues reported online in the &lt;em&gt;Canadian Medical Association Journal&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The association was significant for skiers and snowboarders alike.&lt;br&gt;
&lt;br&gt;Although there has been some concern that use of a helmet could increase the risk of neck injury because of the extra weight it adds to the head, especially with children, the studies did not confirm any danger.&lt;/p&gt;
&lt;p&gt;&quot;Based on our findings, we encourage the use of helmets among skiers and snowboarders,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;Various reports have estimated that 9% to 19% of injuries that occur on the slopes are head injuries and 1% to 4% are neck injuries.&lt;/p&gt;
&lt;p&gt;Traumatic brain injury is the leading cause of death and serious injury among skiers and snowboarders.&lt;/p&gt;
&lt;p&gt;A recent example was the training accident of U.S. Olympic hopeful snowboarder Kevin Pearce, who suffered a severe traumatic brain injury when he fell and hit his head on the edge of a half pipe on New Year&apos;s Eve. He was wearing a helmet.&lt;/p&gt;
&lt;p&gt;Although injury prevention efforts in alpine activities have focused on helmets, there were no systematic reviews of their effectiveness, the new study&apos;s authors noted.&lt;/p&gt;
&lt;p&gt;So Hagel and colleagues assembled data from 10 case-control studies, one case-control/case-crossover study, and one cohort study, totalling 9,829 participants who were wearing helmets and 36,735 who weren&apos;t. The studies evaluated head injury, neck injury, or both.&lt;/p&gt;
&lt;p&gt;In addition to protecting adults from head injury, the researchers found, helmets also appeared to protect children younger than 13 (OR 0.39, 95% CI 0.23 to 0.65).&lt;/p&gt;
&lt;p&gt;While two of four studies looking at potentially severe head trauma  --  resulting in referral to an emergency physician or hospital for treatment or evacuation by ambulance  --  found a reduced risk in those wearing helmets, the other two found no effect.&lt;/p&gt;
&lt;p&gt;There was some evidence that risk of head injury was reduced for males wearing helmets, but not for females, although sex was not found to be a significant modifier of the relationship between helmet use and injury risk (&lt;em&gt;P&lt;/em&gt;=0.09).&lt;/p&gt;
&lt;p&gt;Helmet use was not associated with risk of neck injury, even among children, which &quot;is consistent with biomechanical data showing no increase in neck loads associated with helmet use in simulated snowboarding falls,&quot; the researchers noted in the journal.&lt;/p&gt;
&lt;p&gt;The meta-analysis had some limitations, they wrote, including the moderate methodologic quality of the included studies, two different approaches for determining control groups (noninjured skiers and snowboarders versus those with injuries not involving the head or neck), the inclusion of English-language studies only, and variations in confounders, definitions of head injury, and places of and personnel involved in diagnosis.&lt;/p&gt;
&lt;p&gt;In addition, the researchers were unable to examine the results in terms of the design, quality, or fit of the helmets for cases.&lt;/p&gt;
&lt;p&gt;&quot;Methodologically rigorous research is required to determine which types of helmets provide the best protection,&quot; they wrote.&lt;/p&gt;

He also holds a Population Health Investigator Award from the Alberta Heritage Foundation for Medical Research and a New Investigator Award from the Canadian Institutes of Health Research.&lt;/p&gt;&lt;p&gt;One of his co-authors holds a doctoral studentship from the Alberta Heritage Foundation for Medical Research.&lt;/p&gt;&lt;p&gt;The authors reported no conflicts of interest.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

      &lt;p&gt;Doctor&apos;s Orders&lt;em&gt; is a feature in the collaboration between &lt;/em&gt;MedPage Today &lt;em&gt;and&lt;/em&gt; ABC News&lt;em&gt;. In this monthly segment we explore medical issues of interest to physicians and their patients alike. This month, we look at addiction and addictive behaviors, and what neuroimaging studies have revealed about why it&apos;s so hard to break bad habits. &lt;/em&gt;&lt;/p&gt;&lt;hr&gt;

&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;By the end of January, many New Year&apos;s resolutions have been tossed out with the leftover holiday cookies. That&apos;s because change is hard  --  and neuroscientists are learning why.&lt;br&gt;
&lt;br&gt;Advances in neuroimaging have enabled researchers to peer inside the brains of addicts and patients with addictive behaviors. They can see in real-time what gets patients hooked: how the brain&apos;s reward system  --  based largely on the neurotransmitter dopamine  --  thirsts for more, while inhibitory control centers experience a system failure.&lt;br&gt;
&lt;br&gt;The pattern is similar across all kinds of behaviors  --  from cocaine and tobacco addiction to overeating. That&apos;s why changing your mind may be the first step toward breaking a habit, but altering the brain&apos;s neural machinery is the real challenge.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Hijacked Pathways&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Drug-taking and other addictive behaviors &quot;hijack&quot; the brain&apos;s reward system, says Petros Levounis, MD, director of the Addiction Institute of New York at St. Luke&apos;s and Roosevelt Hospitals in Manhattan.&lt;/p&gt;
&lt;p&gt;In normal patients, dopamine plays a major role in motivation and reward, surging before and during a pleasurable activity  --  say, eating or sex  --  to make patients want to repeat a behavior that&apos;s crucial to the survival of the species.&lt;/p&gt;
&lt;p&gt;Dopaminergic pathways connect the limbic system, responsible for emotion, with the hippocampus, etching rewarding behaviors into the brain by creating strong, salient memories.&lt;/p&gt;
&lt;p&gt;The problem arises when the memory and the craving to recapture it takes over a person&apos;s life.&lt;/p&gt;
&lt;p&gt;&quot;Imagine what a strong hold these hijacked reward pathways take on our brains and our whole existence when they&apos;re so closely connected, geographically and anatomically speaking, with our memories and our emotions,&quot; Levounis says.&lt;/p&gt;
&lt;p&gt;As the dopamine surge repeats and repeats, it gains speed, but the brakes begin to fail: Normal function in the brain&apos;s frontal lobes, responsible for inhibitory control and executive functioning (read: willpower), tends to decrease in addicts.&lt;/p&gt;
&lt;p&gt;&quot;Ultimately,&quot; Levounis says, &quot;the war on drugs is a war between the hijacked reward pathways that push the person to want to use, and the frontal lobes, which try to keep the beast at bay. That is the essence of addiction.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Similar Patterns&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;These neural pathways have been well studied in the brains of hardcore addicts. Now, researchers say they see similar pathways involved in other bad behaviors.&lt;/p&gt;
&lt;p&gt;Gene-Jack Wang, MD, of Brookhaven National Laboratory on New York&apos;s Long Island, has conducted several brain imaging studies of obese patients using PET-CT scans.&lt;/p&gt;
&lt;p&gt;The scans have revealed similarities in brain activity  --  or a lack thereof  --  between patients addicted to cocaine or alcohol, and those &quot;addicted&quot; to eating. Normally, the PET scan lights up when a contrast of radioactive glucose is metabolized, revealing an area of red activity in the center of the brain.&lt;/p&gt;
&lt;p&gt;But in both drug-addicted and obese patients, the scans show very little red activity, because there aren&apos;t enough receptors to which the radioactive glucose can bind. Wang says the decreased availability of dopamine receptors is the brain&apos;s way of coping with a constant dopamine overload.&lt;/p&gt;
&lt;p&gt;&quot;If a person constantly has an excess of dopamine, the brain will down-regulate,&quot; Wang says, explaining the principle commonly referred to as tolerance. &quot;Once the system is down-regulated, we have to do more in order to get the same amount of feeling in our normal state.&quot;&lt;/p&gt;
&lt;p&gt;Thus, obese patients &quot;will want to eat more in order to compensate for their down-regulated system.&quot;&lt;/p&gt;
&lt;p&gt;In other experiments, Wang and his colleagues have also found that a higher body mass index (BMI) correlated with lower prefrontal cortex function  --  the area associated with inhibitory control.&lt;/p&gt;
&lt;p&gt;&quot;If they&apos;re obese,&quot; Wang said, &quot;they have a problem controlling their eating behaviors.&quot;&lt;/p&gt;
&lt;p&gt;Those studies also revealed that a higher BMI was linked to a decrease in memory and executive functioning.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Out of Control&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Ed Susman was 293 pounds when he decided to join a clinical trial for an investigational weight-loss drug and chronicle his year-long experience for &lt;em&gt;MedPage Today&lt;/em&gt;. (See &lt;a href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; mce_href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; target=&quot;_blank&quot;&gt;Journalist Participant to Present Insider View of Weight-Loss Trial&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Eating, to him, was a &quot;compulsion&quot;  --  as was biting his nails, a habit he picked up at age 4.&lt;/p&gt;
&lt;p&gt;Over the course of the trial, not only did Susman lose 52 pounds, he also stopped his nail-biting.&lt;/p&gt;
&lt;p&gt;He doesn&apos;t yet know if he was in the drug arm of the trial, but he strongly suspects he wasn&apos;t experiencing a placebo effect.&lt;/p&gt;
&lt;p&gt;&quot;I believe I was on the drug because it controlled a compulsion that I had had for 50 years,&quot; Susman says of the nail-biting. &quot;This stopped it cold.&quot;&lt;/p&gt;
&lt;p&gt;Unfortunately, he says, the same didn&apos;t happen with his eating habits, but he&apos;s gained back only 10 of those 52 pounds in the year since his participation in the trial ended.&lt;/p&gt;
&lt;p&gt;The still-investigational drug is lorcaserin  --  a combination of benzazepine and hydrochloride, two neurological agents. Susman says it is &quot;supposed to improve your willpower, your ability to overcome compulsions.&quot;&lt;/p&gt;
&lt;p&gt;Lorcaserin is a selective 5-HT&lt;sub&gt;2C&lt;/sub&gt; receptor agonist, working through the serotonin system, which regulates appetite, mood, and motor behavior.&lt;/p&gt;
&lt;p&gt;Two other investigational obesity drugs target the dopamine reward system  --  Contrave, which is a combination of bupropion and naltrexone, and Qnexa, which combines phentermine and topiramate.&lt;/p&gt;
&lt;p&gt;&quot;Some medications that have used similar dopamine modulation, until now, have failed,&quot; Wang said. &quot;These two companies are using the command of the modulation of the dopamine system with other neurological systems, such as the opiate or norepinephrine system. According to the trials, they&apos;ve been very effective.&quot;&lt;/p&gt;
&lt;p&gt;Wang called the new medications &quot;a bright light for the treatment of obesity.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Kicking the Habit&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Basically, the idea of medications that act on the dopamine system is &quot;to cool down those reward pathways,&quot; Levounis says. There are two strategies for doing so: an agonist strategy, or an antagonist strategy.&lt;/p&gt;
&lt;p&gt;The agonist strategy is &quot;feeding the beast, providing activity in the cell so that the cravings go down,&quot; Levounis said. Classic examples are nicotine patches, or methadone for opioid dependence.&lt;/p&gt;
&lt;p&gt;On the other hand, the antagonist strategy is to block the receptors. Naltrexone, for example, will block opioid receptors so that the drug addict won&apos;t feel anything if he or she attempts to get high.&lt;/p&gt;
&lt;p&gt;&quot;After a while, you say, &apos;This is not worth my time, my money, my trouble,&apos; so you stop using,&quot; Levounis explains.&lt;/p&gt;
&lt;p&gt;These have been the two main strategies in addiction pharmacotherapy, but there&apos;s now a &quot;third avenue&quot;  --  the partial agonist approach.&lt;/p&gt;
&lt;p&gt;The partial agonist is one molecule that blocks most receptors while still providing just a little bit of an &quot;oomph&quot; to calm cravings. That&apos;s how varenicline (Chantix) helps smokers quit, and how buprenorphine gets junkies off heroin or other opioids.&lt;/p&gt;
&lt;p&gt;But what about inhibitory control? What if medications could ramp up will power?&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s an area of active research,&quot; Levounis says. &quot;There are some medications proposed, but nothing to write home about.&quot;&lt;/p&gt;
&lt;p&gt;He said treatment is typically twofold. For addicts, psychiatrists will try to &quot;cool down&quot; the reward pathways, often with medication. Then, they target the diminished frontal lobes.&lt;/p&gt;
&lt;p&gt;&quot;We try to beef up the frontal lobes as much as we can, and we do that with psychotherapy,&quot; Levounis said.&lt;/p&gt;
&lt;p&gt;Researchers agree that psychotherapy is key to regaining self-control, and it&apos;s the predominant treatment used in patients with addictive behaviors.&lt;/p&gt;
&lt;p&gt;Mark Smaller, PhD, a psychoanalyst in private practice in Chicago, said psychotherapy often reveals an underlying cause for an addiction or compulsive behavior. Usually, it&apos;s anxiety or depression.&lt;/p&gt;
&lt;p&gt;Acknowledging those problems may help change behaviors. Once they&apos;re realized, a patient can start working against them, with the help of the brain&apos;s own neuroplasticity. Essentially, neurons can disconnect and reconnect, or loosen their connections and tighten them, which often manifests in noticeable change.&lt;/p&gt;
&lt;p&gt;&quot;[Psychological] insights can actually begin to change brain chemistry and diffuse compulsions,&quot; he said. &quot;If you address those issues, you can have a positive impact on your life that can change the chemistry of your brain.&quot;&lt;/p&gt;
&lt;p&gt;Smaller said it &quot;creates a new psychological  --  if not neurological  --  structure that can help regulate behavior.&quot;&lt;/p&gt;
&lt;p&gt;Although research on neuroplasticity is relatively young, the concept of &quot;rewiring&quot; the brain is not new.&lt;/p&gt;
&lt;p&gt;In fact, too often, the electrician metaphor has been employed as an excuse for indulging, an explanation for a New Year&apos;s resolution deferred: &quot;I can&apos;t stop eating chocolate, I&apos;m just not wired that way.&quot;&lt;/p&gt;

                     score="-0.004"
                     href="http://www.medpagetoday.com/Neurology/HeadTrauma/tb/18000?impressionId=1265752808103"
                     
      Whether a clinician calls a mild traumatic brain injury a concussion or not appears to influence how serious the injury is considered to be, researchers found.&lt;br&gt;
&lt;br&gt;Among children admitted for a traumatic brain injury, those who were told they had a concussion were discharged significantly earlier (OR 1.49, 95% CI 1.15 to 1.94) and returned to school sooner (OR 2.42, 95% CI 1.56 to 3.73) than those who were not given the label, Carol DeMatteo, MSc, of McMaster University in Hamilton, Ontario, and colleagues reported in the February issue of &lt;em&gt;Pediatrics&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The trends remained significant even after adjusting for the severity of the head injury and the presence of other injuries.&lt;/p&gt;
&lt;p&gt;&quot;We suggest that the [concussion] label itself conveys a message and also directs outcomes,&quot; the researchers wrote. &quot;If we want to encourage full reporting with subsequent adequate management and convalescence, perhaps we should use the term &apos;mild traumatic brain injury.&apos;&quot;


 &lt;p&gt;Disagreeing was Kenneth Perrine, PhD, a neuropsychologist at Hackensack University Medical Center in New Jersey.
    &lt;p&gt;&quot;Granted, concussion is by definition a mild brain injury, but it&apos;s so transient that I think it would be a disservice both to the public and for research to continue to confuse mild traumatic brain injury with concussion,&quot; said Perrine, who was not involved in the study.
    &lt;p&gt;He said a true concussion is characterized by feeling like one is in a fog, fatigue, sensitivity to light and sound, headache, blurred vision or other visual disturbances, and feeling off balance.
    &lt;p&gt;A mild traumatic brain injury, on the other hand, has longer-lasting effects and is not usually accompanied by concussion symptoms. Retrograde amnesia, post-traumatic amnesia, and more severe memory loss would occur, he said.
    &lt;p&gt;&quot;They are two distinct entities both from what we call it and from a prognostic standpoint,&quot; said Perrine, who is also consulting neuropsychologist for the New York Jets.
    &lt;p&gt;But, although the term concussion is used widely in clinical records and has garnered much attention in recent years because of head injuries to athletes at all levels of sports, an accepted definition does not exist, according to DeMatteo and her colleagues.&lt;/p&gt;



&lt;p&gt;&quot;Clinicians may use the concussion label because it is less alarming to parents than the term &quot;mild brain injury,&quot; with the intent of implying that the injury is transient with no signi&amp;#64257;cant long-term health consequences,&quot; they said.&lt;/p&gt;

&lt;p&gt;Commenting on the study, Wendy Wright, MD, a neurologist at Emory University in Atlanta, said in an e-mail, &quot;This study puts a spotlight on the issue that concussion is not always taken as seriously as it should be, partly because concussion encompasses a spectrum of disease.&quot;&lt;/p&gt;
&lt;p&gt;She said parents, coaches, teammates, and the individual with the concussion may not believe the injury is serious because symptoms are transient.&lt;/p&gt;
&lt;p&gt;That perception appears to be held by both clinicians and parents alike. DeMatteo and colleagues noted in the journal that during recruitment of the current study, both groups were heard saying, &quot;He doesn&apos;t have a head injury, he has a concussion.&quot;&lt;/p&gt;
&lt;p&gt;However, Wright said, &quot;it must be noted that concussion means brain injury.&quot;&lt;/p&gt;


&lt;p&gt;To explore how the term is used clinically, DeMatteo and colleagues analyzed the records of 434 children admitted to McMaster Children&apos;s Hospital with a diagnosis of acquired brain injury.&lt;/p&gt;
&lt;p&gt;Of those determined to have a traumatic brain injury, 72.7% had a mild injury according to the Glasgow Coma Scale. Nearly one-third (32.4%) were said to have a concussion.&lt;/p&gt;
&lt;p&gt;The concussion label was more likely to be given to children with a mild injury (&lt;em&gt;P&lt;/em&gt;=0.03), but the association was weak, according to the researchers, and nearly one-quarter (24%) of children with moderate or severe scores were also said to have a concussion.&lt;/p&gt;
&lt;p&gt;&quot;This leads one to question the use of the term as being reflective of mild injury and again supports the existence of confusion about what a concussion really is and how the term should best be used in the care of children,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;Our findings, both in the return-to-school data and the phenomenon we experienced during recruitment, suggest that if a child is given a diagnosis of concussion, then the family is less likely to consider it as a brain injury,&quot; the researchers said.&lt;/p&gt;
&lt;p&gt;They acknowledged some limitations of the study, including the fact that data from medical charts may have had missing information and a lack of control over the validity of measurements and that their use of only a single center might influence the results.&lt;/p&gt;
&lt;p&gt;Further, they wrote, some measures, such as CT frequency, might be inflated because only children who were admitted to the hospital were included in the study. &lt;ul&gt; &lt;/ul&gt;&lt;/p&gt;

The &lt;em&gt;CanChild&lt;/em&gt;&lt;em&gt;&lt;/em&gt; Center for Childhood Disability Research is supported by the Ontario Ministry of Health and Long-Term Care.&lt;/p&gt;&lt;p&gt;The authors reported that they had no relevant financial disclosures to make.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

      &lt;p&gt;MIAMI BEACH  --  Elderly patients sedated with morphine or haloperidol (Haldol) in surgical intensive care units were less likely to to be discharged to their homes and more likely to be discharged to a nursing facility than patients given other sedatives, often resulting in a poorer quality of life, researchers reported here.&lt;/p&gt;
&lt;p&gt;Patients who received morphine were 2.57 times more likely to be discharged to a nursing home, rehabilitation center, or a skilled nursing facility (&lt;em&gt;P&lt;/em&gt;=0.029), Carrie Miller, MS, CRNP of the Hospital of the University of Pennsylvania in Philadelphia, told attendees at the annual meeting of the Society of Critical Care Medicine.&lt;/p&gt;
&lt;p&gt;Patients who were given haloperidol were 12.46 times more likely to be discharged to one of those facilities rather than to their home.&lt;/p&gt;
&lt;p&gt;Similarly, the risk of having a significantly reduced function from baseline admission was five times greater if the patient had received haloperidol (&lt;em&gt;P&lt;/em&gt;=0.044) and 2.76 times more likely if the patient had received morphine (&lt;em&gt;P&lt;/em&gt;=0.011), Miller said.&lt;/p&gt;
&lt;p&gt;&quot;While older adults frequently require medications to treat pain, anxiety, and delirium, little is know about the effects these medication have on older adults&apos; functional ability or quality of life,&quot; Miller said.&lt;/p&gt;
&lt;p&gt;To shed some light on the question, she and her colleagues evaluated 114 patients in three surgical ICUs. Mean age was about 75, some 60% were men, and 85% were white. Overall, 37% were undergoing general surgical procedures, while 35% had undergone vascular procedures and 16% were trauma patients.&lt;/p&gt;
&lt;p&gt;Patients&apos; level of consciousness and delirium status were assessed daily and information about medication use was gleaned from the ICU flow sheet and the computerized administration record.&lt;/p&gt;
&lt;p&gt;The most frequently used narcotic in the surgical ICU was fentanyl (Duragesic), administered to 77 patients; the most frequently used sedative was midazolam (Versed); and the most frequently used antipsychotic was haloperidol.&lt;/p&gt;
&lt;p&gt;Miller and her colleagues noted that use of propofol (Diprivan) appeared to be associated with better outcomes as far as discharge to one&apos;s home was concerned.&lt;/p&gt;
&lt;p&gt;They noted that there was &quot;considerable discrepancy&quot; between medication usage and dosage recorded on the patients&apos; flow sheet and medication administration record. &quot;Researchers and clinicians should consider that administered prn medications may not always be recorded on the nursing flow sheet,&quot; they concluded.&lt;/p&gt;
&lt;p&gt;The study did not control for confounding variables such as the severity of illness or comorbidities that may have affected outcomes, Miller said.&lt;/p&gt;
&lt;p&gt;&quot;This is an interesting study,&quot; said Suzan Streichenwein, MD, a private practice geriatric psychiatrist in West Palm Beach, Fla. &quot;It would be valuable for future studies to include the severity of illness or more specific details about the type of surgery relative to the dosages of morphine used and its influence on the discharge functional outcomes.&lt;/p&gt;
&lt;p&gt;&quot;Tests diagnosing mild cognitive impairment and/or dementia preop versus postop as well as the time period under anesthesia in relation to outcomes would also be helpful,&quot; said Streichenwein, who was not involved in the study.&lt;/p&gt;
&lt;p&gt;Streichenwein told &lt;em&gt;MedPage Today&lt;/em&gt; that other possible confounding factors require further studies in this area.&lt;/p&gt;
