                     score="0.012"

      Catheter-related infections aren&apos;t inevitable in the ICU, according to a quality initiative that maintained rates at nearly zero for three years in Michigan hospitals.&lt;br&gt;
&lt;br&gt;The maintenance phase, after initial implementation of low-tech measures such as handwashing and removal of unneeded catheters, saw no rebound in catheter-related infections, Peter J. Pronovost, MD, PhD, of Johns Hopkins, and colleagues reported online in &lt;em&gt;BMJ&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The first 18 months of their &lt;a href=&quot;http://www.medpagetoday.com/InfectiousDisease/GeneralInfectiousDisease/4771&quot; mce_href=&quot;http://www.medpagetoday.com/InfectiousDisease/GeneralInfectiousDisease/4771&quot; target=&quot;_blank&quot;&gt;Keystone ICU initiative&lt;/a&gt; dropped catheter-related interventions from a mean of 7.7 and median of 2.2 per 1,000 catheter days down to 1.3 and 0, respectively.&lt;br&gt;
&lt;br&gt;At the 36 month mark, infection rates remained almost nil, at a mean of 1.1 and median of 0 per 1,000 catheter days.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&quot;For the most part, hospitals view these infections as inevitable, as the cost of doing business, that patients are too sick, that these can&apos;t be prevented,&quot; Pronovost told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;That&apos;s just not true.&quot;&lt;/p&gt;
&lt;p&gt;Catheter-related infections are the number one cause of preventable death in hospitals and ICUs, ahead of even ventilator-related pneumonia, he noted.&lt;/p&gt;
&lt;p&gt;The changes seen at the 90 Michigan ICUs that stayed with the catheter-related infection initiative were impressive, representing one of the largest and longest improvements the field has seen.&lt;/p&gt;
&lt;p&gt;Often, quality initiatives fail on durability after the study funding and resources disappear, and hospitals are left on their own, Pronovost noted.&lt;/p&gt;
&lt;p&gt;&quot;If you push you might get some effect, but then you stop pushing  --  in other words the external control goes away  --  and the performance goes right back down,&quot; he said in an interview. &quot;It can&apos;t just be the stick that drives it.&quot;&lt;/p&gt;
&lt;p&gt;The intervention started with 103 ICUs that implemented strategies to reduce rates of catheter-related bloodstream infections rates over 18 months, with measurement and feedback of infection rates.&lt;/p&gt;
&lt;p&gt;The strategies aimed at improving execution of five evidence-based recommendations, as follows: &lt;ul&gt; &lt;li&gt;Hand washing before insertion of the catheter&lt;/li&gt; &lt;li&gt;Using gowns and full barrier precautions at catheter insertion&lt;/li&gt; &lt;li&gt;Cleaning the skin with chlorhexidine before catheter insertion&lt;/li&gt; &lt;li&gt;Avoiding the femoral site when possible&lt;/li&gt; &lt;li&gt;Removing unnecessary catheters&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Then, over the subsequent 18-month maintenance period, ICU teams were instructed to integrate this intervention into staff orientation, to collect monthly data from hospital infection control staff, and to report infection rates to physicians and others.&lt;/p&gt;
&lt;p&gt;Along with the sustained reduction in overall catheter-related infections, the researchers found a prolonged reduction in bloodstream infections that was significant during all study periods, compared to baseline.&lt;/p&gt;
&lt;p&gt;Rates decreased from a mean of 7.7 and median 2.7 of per 1,000 catheter days at baseline to 1.3 and 0, respectively, at 16 to 18 months after implementation. They remained at 1.1 and 0 at months 34 to 36 (-1% versus 18 months, 95% CI -9% to +7%).&lt;/p&gt;
&lt;p&gt;ICU teams interviewed attributed the continuously low rates to five factors: &lt;ul&gt; &lt;li&gt;Continued feedback on infection data&lt;/li&gt; &lt;li&gt;Improvements in safety culture as part of the project&lt;/li&gt; &lt;li&gt;An &quot;unremitting belief in the preventability of bloodstream infections&quot;&lt;/li&gt; &lt;li&gt;Involvement of senior leaders&lt;/li&gt; &lt;li&gt;A noncompetitive, shared goal to reduce infection rates throughout the state&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Of these, Pronovost called culture change in the ICUs the key factor to sustainability, although the researchers cautioned that which aspects contributed were not formally evaluated.&lt;/p&gt;
&lt;p&gt;They said they could not determine the impact incentive payments from Blue Cross Blue Shield of Michigan to hospitals that continued their participation  --  payments that were based on performance thresholds in subsequent years.&lt;/p&gt;
&lt;p&gt;Pronovost&apos;s team is now working to implement the quality initiative state-by-state nationwide, supported by the Agency for Healthcare Research and Technology.&lt;/p&gt;
&lt;p&gt;&quot;It seems absurd that this wouldn&apos;t be in every hospital in the country,&quot; he said in an interview. &quot;It&apos;s worked on a large scale, it&apos;s exceedingly cheap, there&apos;s no fancy technology.&quot;&lt;/p&gt;
&lt;p&gt;Success isn&apos;t only for community hospitals, Pronovost emphasized.&lt;/p&gt;
&lt;p&gt;Large, often academic, medical centers frequently express the conviction that their sicker, more complex ICU population wouldn&apos;t produce the same results, that their infections truly are inevitable, he said.&lt;/p&gt;
&lt;p&gt;&quot;To them I say, Not so,&quot; he told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;We have shown at Johns Hopkins, at the University of Michigan, at Pittsburgh, using a similar but different approach, at Tufts  --  many large academic medical centers have had dramatic reductions of these infections.&quot;&lt;/p&gt;

                     score="0.008"
                     href="http://www.medpagetoday.com/HematologyOncology/ProstateCancer/tb/18268?impressionId=1265775131834"
                     
      Men have a slightly, but statistically significant, increased risk of dying from cardiovascular disease in the year after learning they have prostate cancer, researchers found.&lt;br&gt;
&lt;br&gt;The risk was greatest in the first month after diagnosis (standardized mortality ratio 2.05, 95% CI 1.89 to 2.22), Lorelei Mucci, PhD, of Brigham and Women&apos;s Hospital in Boston, and colleagues reported online in the &lt;em&gt;Journal of the National Cancer Institute&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The study, which covered diagnoses made from 1979 through 2004, also found an overall increased risk of suicide in the year following a prostate cancer diagnosis (SMR 1.4, 95% CI 1.2 to 1.6), although the association was not significant after screening for prostate specific antigen (PSA) became widespread.&lt;br&gt;
&lt;br&gt;The findings&lt;em&gt;&lt;/em&gt; are &quot;one additional piece in weighing the pros and cons of PSA screening,&quot; Mucci said in an interview.&lt;br&gt;
&lt;br&gt;She also said that, &quot;not only do [clinicians] need to be treating the cancer, but they need to be thinking about the social support and other support that men may need to deal with this stressful event.&quot;&lt;p&gt;&lt;/p&gt;
&lt;p&gt;A previous study by Mucci&apos;s group that looked at a Swedish population found similarly increased risks of suicide and cardiovascular death following a prostate cancer diagnosis.&lt;/p&gt;
&lt;p&gt;Because PSA testing is more extensive in the U.S., increasing the number of early-stage and indolent cancers detected, the researchers wanted to see whether the results would carry over.&lt;/p&gt;
&lt;p&gt;Using the Surveillance, Epidemiology, and End Results (SEER) Program, they looked at data from 342,497 men who were diagnosed with prostate cancer from 1979 through 2004.&lt;/p&gt;
&lt;p&gt;The number of diagnoses steadily increased throughout the study period  --  from 6,106 in 1979 to 17,688 in 2004.&lt;/p&gt;
&lt;p&gt;But the percentage of cancers that were metastatic dropped from 18.2% in the pre-PSA period (1979 to 1986) to 5% in the period of widespread testing (1993 to 2004).&lt;/p&gt;
&lt;p&gt;During the study, 148 men committed suicide within one year of learning their diagnosis, higher than the 105.2 that would be expected in the general U.S. male population.&lt;/p&gt;
&lt;p&gt;The elevated risk was only evident prior to 1993, when PSA testing became more widely used. The authors suggested that this was likely because of the potentially lower degree of stress associated with the diagnosis of indolent prostate cancer.&lt;/p&gt;
&lt;p&gt;&quot;So that&apos;s reassuring,&quot; Mucci said.&lt;/p&gt;
&lt;p&gt;However, another 6,845 men died of cardiovascular disease, which was also higher than the expected 6,282.9.&lt;/p&gt;
&lt;p&gt;Contrary to the findings regarding suicide, the risk of cardiovascular death in the first month after hearing a diagnosis was significantly increased throughout the study period.&lt;/p&gt;
&lt;p&gt;Prostate cancer patients who were not married at the time of diagnosis had higher relative risks of both suicide and cardiovascular death than married patients.The authors suggested that this may be because &quot;having someone close to confide in might alleviate the psychological stress experienced from receiving a cancer diagnosis.&quot;&lt;/p&gt;
&lt;p&gt;They also observed a clear trend between higher relative risks for suicide and cardiovascular death among patients diagnosed with a metastatic tumor, which clearly would be more stressful than diagnosis of a clinically localized tumor.&lt;/p&gt;
&lt;p&gt;&quot;This finding might further explain the decreasing excess risks that have been observed in the PSA era, in which the proportion of advanced tumors was small (i.e., 18.2% metastatic tumors in the pre-PSA era and 5.0% in the PSA era),&quot; they wrote.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Risk of cardiovascular death was magnified for patients with metastatic tumors (SMR 3.22, 95% CI 2.68 to 3.84) compared with those with local or regional tumors (SMR 1.57, 95% CI 1.42 to 1.74)(&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Prostate cancer patients who were not married at the time of diagnosis had higher relative risks of both suicide and cardiovascular death than married patients.&lt;/p&gt;
&lt;p&gt;The authors acknowledged some limitations of the study, including the lack of a cancer-free group as reference and the lack of information on physical or mental health status, other prevalent disorders or comorbid illness at diagnosis, and prostate cancer treatment.&lt;/p&gt;

                     title="ADT for Prostate Cancer Raises Heart Risks"
                     score="0.007"
                     href="http://www.medpagetoday.com/Urology/ProstateCancer/tb/18250?impressionId=1265775131834"
                     
      &lt;p&gt;Androgen deprivation therapy (ADT) for prostate cancer can exacerbate cardiac risk factors and may increase the risk of heart attack and cardiac death, according to an advisory supported by four medical organizations.&lt;/p&gt;
&lt;p&gt;However, the groups did not offer specific guidelines for clinicians on when to employ ADT therapy or avoid it.&lt;/p&gt;
&lt;p&gt;Clinical trials have shown that ADT increases body weight, decreases lean mass and increases fat mass, reduces insulin sensitivity, and triggers or worsens dyslipidemia.&lt;/p&gt;
&lt;p&gt;Several studies have demonstrated a significant increase in cardiovascular death in prostate cancer patients treated with hormonal therapy or bilateral orchiectomy, although some studies have shown no association between ADT and increased cardiovascular risk, according to a report that will appear in the Feb. 16 issue of &lt;em&gt;Circulation: Journal of the American Heart Association&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Some evidence also suggests ADT may predispose men to metabolic syndrome.&lt;/p&gt;
&lt;p&gt;&quot;Based on current data, it was appropriate to conclude that there may be a relationship between ADT therapy in patients with prostate cancer and future cardiovascular risk,&quot; Glenn N. Levine, MD, of Baylor College of Medicine in Houston and chair of the advisory writing committee, said in a statement.&lt;/p&gt;
&lt;p&gt;The writing committee comprised representatives of the American Heart Association, American Urological Association, and American Cancer Society. Additionally, the American Society for Radiation Oncology endorsed the advisory.&lt;/p&gt;
&lt;p&gt;The authors&apos; review of literature showed that ADT increased cardiovascular risk in 1% to 6% of various studies&apos; patient populations. With that in mind, &quot;the decision about whether to initiate ADT should be based on weighing the benefits of therapy with this potential modest risk,&quot; Levine said.&lt;/p&gt;
&lt;p&gt;The decision to initiate ADT should remain with the physician who has responsibility for treating a patient with prostate cancer, the authors wrote. That includes patients with known cardiac disease.&lt;/p&gt;
&lt;p&gt;&quot;It is the consensus of the writing group that there is no clear indication for patients for whom ADT is believed to be beneficial to be referred to internists, endocrinologists, or cardiologists for evaluation before initiation of ADT,&quot; the authors said.&lt;/p&gt;
&lt;p&gt;&quot;The decision as to whether or not to initiate ADT in patients with cardiac disease, in whom the benefits of therapy would be weighed against any possible risks, is most appropriately made by the physician treating the patient for prostate cancer.&quot;&lt;/p&gt;
&lt;p&gt;However, the potential adverse metabolic effects warrant periodic evaluation by a patient&apos;s primary care physician, they added.&lt;/p&gt;
&lt;p&gt;Noting a lack of clinical guidance for follow-up of patients treated with ADT, the advisory authors concluded that at least an annual assessment of blood glucose and lipids seems reasonable. They also called for prospective assessment of cardiovascular risk factors before and after ADT is begun in future clinical trials.&lt;/p&gt;

                     href="http://www.medpagetoday.com/CriticalCare/Sepsis/tb/18160?impressionId=1265775131834"
                     
      Septic shock patients treated with a corticosteroid get no survival advantage from tight glucose control or addition of a second corticosteroid to provide more mineralocorticoid activity, according to results of a randomized trial.&lt;br&gt;
&lt;br&gt;Aiming for normoglycemia at 80 to 110 mg/dL rather than the standard 150 mg/dL had no impact on inhospital mortality rates (45.9% versus 42.9%, &lt;em&gt;P&lt;/em&gt;=0.50), Djillali Annane, MD, of H&amp;#244;pital Raymond Poincar&amp;#233; in Garches, France, and colleagues found.&lt;br&gt;
&lt;br&gt;Inhospital mortality was likewise similar whether patients got hydrocortisone (Solu-Cortef) alone or with the addition of fludrocortisone ([Florinef] 42.9% versus 45.8%, &lt;em&gt;P&lt;/em&gt;=0.50), they reported in the Jan. 27 issue of the &lt;em&gt;Journal of the American Medical Association&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;This aggressive treatment strategy should not be routine, the researchers recommended.&lt;/p&gt;
&lt;p&gt;These findings largely match the general lack of benefit seen with tight glycemic control in recent studies with ICU patients overall.&lt;/p&gt;
&lt;p&gt;The prematurely terminated &lt;a href=&quot;http://www.medpagetoday.com/MeetingCoverage/SCCM/5096&quot; mce_href=&quot;http://www.medpagetoday.com/MeetingCoverage/SCCM/5096&quot; target=&quot;_blank&quot;&gt;European Glucontrol Trial&lt;/a&gt; found no mortality benefit but a seven-fold higher risk of hypoglycemia with an 80 to 110 mg/dL target in the ICU.&lt;/p&gt;
&lt;p&gt;In the &lt;a href=&quot;http://www.medpagetoday.com/CriticalCare/Intensivists/13397&quot; mce_href=&quot;http://www.medpagetoday.com/CriticalCare/Intensivists/13397&quot; target=&quot;_blank&quot;&gt;NICE-SUGAR&lt;/a&gt; study, 90-day mortality was actually higher in the tight glucose control group (27.9% versus 24.9%, &lt;em&gt;P&lt;/em&gt;=0.02), although there was a trend for benefit in patients who got corticosteroids (&lt;em&gt;P&lt;/em&gt;=0.06).&lt;/p&gt;
&lt;p&gt;Glucose targets are being re-evaluated across medicine as the &quot;lower is better&quot; paradigm has had a safety asterisk added everywhere from diabetes care to the ICU, noted Richard Bergenstal, MD, American Diabetes Association president for medicine and science.&lt;/p&gt;
&lt;p&gt;&quot;All of a sudden it&apos;s becoming more than a single number,&quot; he told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;Now be it inpatient or outpatient, we&apos;re realizing that ... you have to do it while you&apos;re minimizing hypoglycemia.&quot;&lt;/p&gt;
&lt;p&gt;A more nuanced and &lt;a href=&quot;http://www.medpagetoday.com/Cardiology/Diabetes/13818&quot; mce_href=&quot;http://www.medpagetoday.com/Cardiology/Diabetes/13818&quot; target=&quot;_blank&quot;&gt;individualized&lt;/a&gt; strategy is prudent, Bergenstal agreed.&lt;/p&gt;
&lt;p&gt;The current clinical uncertainty underscores the need for large-scale international cooperation to get adequately powered trials, according to an accompanying editorial.&lt;/p&gt;
&lt;p&gt;In it, Greet Van den Berghe, MD, PhD, of the Catholic University of Leuven, Belgium, cautioned that Annane&apos;s Corticosteroids and Intensive Insulin Therapy for Septic Shock (COIITSS) study was grossly underpowered.&lt;/p&gt;
&lt;p&gt;The initial studies that led to rapid adoption of intensive insulin therapy in ICUs around the world had suggested an absolute reduction in mortality of only 3%, whereas the COIITSS study projected a 12.5% absolute benefit.&lt;/p&gt;
&lt;p&gt;More importantly, the study achieved mean glucose levels of only between 120 and 130 mg/dL in the intervention group for whom the aim was 80 to 110 mg/dL, which resulted in considerable overlap with the standard care group for whom mean levels were about 145 mg/dL.&lt;/p&gt;
&lt;p&gt;This could account for the lack of difference in outcome, Van den Berghe said.&lt;/p&gt;
&lt;p&gt;But the intensive insulin group did have &quot;markedly&quot; lower blood glucose levels for the duration of their ICU stay and spent more time in the 80 to 110 mg/dL range compared with the standard care group (both &lt;em&gt;P&lt;/em&gt;&amp;lt;0.00001), the researchers noted.&lt;/p&gt;
&lt;p&gt;Because corticosteroids further aggravate the &quot;diabetes of injury&quot; seen with septic shock, Annane&apos;s group undertook a multicenter trial of 509 adults treated for septic shock with multiple organ dysfunction over a three year period at 11 ICUs in France.&lt;/p&gt;
&lt;p&gt;Patients were randomly assigned to tight glucose control using continuous intravenous insulin infusion to target a glucose level of 80 to 110 mg/dL or conventional insulin therapy targeted to guidelines-recommended 150 mg/dL or under. They were additionally randomized to receive hydrocortisone alone (50-mg bolus every six hours) or in combination with fludrocortisone (50-&amp;#956;g tablets once daily) for seven days.&lt;/p&gt;
&lt;p&gt;Aside from the lack of inhospital mortality advantage, tight glucose control also failed to produce a benefit for the following secondary endpoints: &lt;ul&gt; &lt;li&gt;Overall survival (hazard ratio 1.04, &lt;em&gt;P&lt;/em&gt;=0.78) &lt;/li&gt; &lt;li&gt; ICU length of stay for survivors (median 10 versus nine days, &lt;em&gt;P&lt;/em&gt;=0.68)&lt;/li&gt; &lt;li&gt;Duration of hospital stay overall (24 versus 22 days, &lt;em&gt;P&lt;/em&gt;=0.87)&lt;/li&gt; &lt;li&gt;Median vasopressor-free days (four for both, P=0.58)&lt;/li&gt; &lt;li&gt;Median mechanical ventilation-free days (10 versus 13, &lt;em&gt;P&lt;/em&gt;=0.51)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Nor was there evidence for interaction with fludrocortisone in the primary endpoint (relative risk 0.89 versus 0.91 hydrocortisone alone, &lt;em&gt;P&lt;/em&gt;=0.31) or benefit in any other endpoint.&lt;/p&gt;
&lt;p&gt;The one effect of intensive insulin appeared to be an increase in episodes of severe hypoglycemia, defined by glucose falling below 40 mg/dL (mean 0.29 versus 0.14 episodes per patient, &lt;em&gt;P&lt;/em&gt;=0.003).&lt;/p&gt;
&lt;p&gt;However, having hypoglycemia did not increase the risk of death in intervention group patients compared with controls (45.2% versus 50%).&lt;/p&gt;
&lt;p&gt;The researchers cautioned that the study did not rule out a benefit from some degree of glucose control compared with none.&lt;/p&gt;
&lt;p&gt;They also noted that healthcare providers were not blinded to administration of fludrocortisone, for which no placebo was available.&lt;/p&gt;

                     title="In Prostate CA, Sexual Decline After Radiation Has Limit (CME/CE)"
                     score="0.004"
                     href="http://www.medpagetoday.com/HematologyOncology/ProstateCancer/tb/18214?impressionId=1265775131834"
                     
      &lt;p&gt;Sexual function declines in the first two years after external beam radiation therapy for prostate cancer but stabilizes thereafter, according to data from a prospective cohort study.&lt;/p&gt;
&lt;p&gt;All parameters of sexual function declined significantly (&lt;em&gt;P&lt;/em&gt;&lt;0.05) in the first two years after external-beam radiation therapy (EBRT), Richard Valicenti, MD, of the University of California Davis, and colleagues found.&lt;/p&gt;
&lt;p&gt;But for years two through six of follow-up, none of the evaluated parameters of sexual function changed significantly.&lt;/p&gt;
&lt;p&gt;Pretreatment sexual function was the strongest predictor of sexual function at any time after EBRT, the investigators reported in the January issue of the &lt;em&gt;International Journal of Radiation Oncology*Biology*Physics&lt;/em&gt;&lt;em&gt;&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Their findings debunk the perception that sexual function declines continually after radiation therapy for prostate cancer.&lt;/p&gt;
&lt;p&gt;&quot;The results of this study allow patients and their partners to have a fuller understanding of the long-term sexual side effects of EBRT, and what they can expect after treatment should aid in deciding on a treatment course,&quot; Valicenti said in a statement.&lt;/p&gt;
&lt;p&gt;Reported rates of impotency after EBRT for prostate cancer have ranged from 8% to 85%, a variation the authors attributed to the different instruments used to assess sexual function. Moreover, many studies included men who received androgen deprivation therapy in addition to EBRT, possibly masking the contributions of radiation therapy to changes in sexual function.&lt;/p&gt;
&lt;p&gt;Several recent studies have suggested that rates of sexual dysfunction increase with follow-up. However, few studies included pretreatment assessment of sexual function or conducted serial assessments of sexual function after EBRT, the authors wrote.&lt;/p&gt;
&lt;p&gt;To shed more light on the question, the investigators prospectively followed 143 men who completed a sexual function questionnaire prior to EBRT for prostate cancer and at each follow-up visit. The questionnaire assessed four domains of sexual function: sexual drive, erectile function, ejaculatory function, and overall satisfaction.&lt;/p&gt;
&lt;p&gt;The mean age of the patients was 69, median Gleason score was 6, and median total radiation dose was 73.8 Gy (range of 66.6 to 79.2 Gy).&lt;/p&gt;
&lt;p&gt;During a median four-years of follow-up, the study participants completed a total of 1,187 questionnaires. Some patients were followed for as long as eight years after EBRT.&lt;/p&gt;
&lt;p&gt;Baseline scores for sexual drive and erectile function were significantly associated with patient age (&lt;em&gt;P&lt;/em&gt;=0.003 and &lt;em&gt;P&lt;/em&gt;=0.004, respectively). Ejaculatory function was significantly associated with age, race, and marital status (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05).&lt;/p&gt;
&lt;p&gt;Scores on all four domains of sexual function, as well as the total score, declined significantly in the first two years after EBRT (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05) compared with baseline values.&lt;/p&gt;
&lt;p&gt;Investigators grouped the patients according to baseline sexual function. Analysis of scores for patients above and below the median sexual function value showed that differences in sexual function persisted over time. Regression analysis showed that baseline score was the best predictor of later scores for all of the domains assessed (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;A separate analysis of scores from years two through six showed no significant changes in any of the domains: sexual drive, &lt;em&gt;P&lt;/em&gt;=0.067; erectile function, &lt;em&gt;P&lt;/em&gt;=0.5; ejaculatory function, &lt;em&gt;P&lt;/em&gt;=0.6; and overall satisfaction, &lt;em&gt;P&lt;/em&gt;=0.44.&lt;/p&gt;
&lt;p&gt;Baseline scores indicated that 74.1% of the study participants were sexually potent before EBRT. Among those who were potent before treatment, 74.4% remained potent at one year and 70.4% at two years after EBRT. The one- and two-year potency rates differed significantly from baseline, but the investigators found no statistically significant change in potency from years two through six.&lt;/p&gt;
&lt;p&gt;&quot;Our data have indicated that the widely held opinion that sexual function has a slow, progressive decline after EBRT might be incorrect,&quot; the authors wrote in conclusion. &quot;Most sexual function decline in men undergoing EBRT for prostate cancer occurred in the first two years after treatment and all domains of sexual function, including erectile dysfunction, then appeared to stabilize.&quot;&lt;/p&gt;
