Hand Hygiene Among Health Care Workers: Is Educating Patients and Families a Feasible Way to Increase Rates?

BACKGROUND: The Centers for Disease Control and Prevention has recommended teaching patients to remind health care workers to disinfect their hands. However, cognitive impairment among patients may hamper such efforts. METHODS: The St. Louis University Mental Status (SLUMS) Examination was administered to randomly selected inpatients at the Omaha VA Medical Center in Omaha, Nebraska. We asked patients and their families about attitudes toward reminding health care workers to disinfect their hands: willingness, feeling comfortable, and feeling responsible. RESULTS: Of 143 patients, 94 completed SLUMS; 9 had normal mental status and appropriate attitudes. Overall, 16 encounters involved patients or family who were well-suited for giving reminders. CONCLUSION: Programs to encourage hospitalized adults to remind staff to perform hand hygiene may encounter barriers related to cognitive impairment and attitudes.

Implementation of a Prevention Bundle to Decrease Rates of Staphylococcus aureus Surgical Site Infection at 11 Veterans Affairs Hospitals.

Importance: While current evidence has demonstrated a surgical site infection (SSI) prevention bundle consisting of preoperative Staphylococcus aureus screening, nasal and skin decolonization, and use of appropriate perioperative antibiotic based on screening results can decrease rates of SSI caused by S aureus, it is well known that interventions may need to be modified to address facility-level factors. Objective: To assess the association between implementation of an SSI prevention bundle allowing for facility discretion regarding specific component interventions and S aureus deep incisional or organ space SSI rates. Design, Setting, and Participants: This quality improvement study was conducted among all patients who underwent coronary artery bypass grafting, cardiac valve replacement, or total joint arthroplasty (TJA) at 11 Veterans Administration hospitals. Implementation of the bundle was on a rolling basis with the earliest implementation occurring in April 2012 and the latest implementation occurring in July 2017. Data were collected from January 2007 to March 2018 and analyzed from October 2020 to June 2023. Interventions: Nasal screening for S aureus; nasal decolonization of S aureus carriers; chlorhexidine bathing; and appropriate perioperative antibiotic prophylaxis according to S aureus carrier status. Facility discretion regarding how to implement the bundle components was allowed. Main Outcomes and Measures: The primary outcome was deep incisional or organ space SSI caused by S aureus. Multivariable logistic regression with generalized estimating equation (GEE) and interrupted time-series (ITS) models were used to compare SSI rates between preintervention and postintervention periods. Results: Among 6696 cardiac surgical procedures and 16 309 TJAs, 95 S aureus deep incisional or organ space SSIs were detected (25 after cardiac operations and 70 after TJAs). While the GEE model suggested a significant association between the intervention and decreased SSI rates after TJAs (adjusted odds ratio, 0.55; 95% CI, 0.31-0.98), there was not a significant association when an ITS model was used (adjusted incidence rate ratio, 0.88; 95% CI, 0.32-2.39). No significant associations after cardiac operations were found. Conclusions and Relevance: Although this quality improvement study suggests an association between implementation of an SSI prevention bundle and decreased S aureus deep incisional or organ space SSI rates after TJAs, it was underpowered to see a significant difference when accounting for changes over time.

Adjunctive Minocycline for Treatment of Posttraumatic Stress Disorder.

INTRODUCTION: Posttraumatic stress disorder (PTSD) is a chronic, debilitating anxiety disorder. While there is evidence that antibiotics such as minocycline may help to improve symptoms in some psychiatric disorders, no human studies have evaluated their potential as a treatment for PTSD. METHODS: We present results from 4 men aged 33 to 59 years who completed a 12-week pilot, prospective, nonrandomized, open-label clinical trial of adjunctive minocycline for veterans diagnosed with PTSD. RESULTS: All 4 patients showed reduction in PTSD symptoms at the end of the 12-week study, and 3 patients showed reduction in depression symptoms. Observed changes in inflammatory biomarkers are discussed. DISCUSSION: Previous studies have reported increased inflammation in PTSD, though evidence of a potential therapeutic effect of minocycline for PTSD has not been reported previously in humans. CONCLUSION: These findings suggest that antibiotics like minocycline may help to reduce symptoms of PTSD, though further investigation is needed to confirm these findings.

Fluoroquinolones and the Risk of Aortopathy: A Systematic Review and Meta-Analysis.

INTRODUCTION: Recent studies have raised concerns that fluoroquinolone use is associated with an increased risk of aortopathy, including aortic aneurysm with and without dissection. OBJECTIVE: We performed a meta-analysis with a comprehensive literature review to further investigate this association. METHODS: This analysis was conducted per PRISMA guidelines. PubMed, Cochrane Library, ClinicalTrials.gov, Embase, Web of Science, and Google Scholar were searched for studies that included adult patients (age >18 years) exposed to fluoroquinolones or control antibiotics (amoxicillin/any other antibiotic) for urinary tract infection or pneumonia with a primary outcome of aortic aneurysm or dissection. Heterogeneity was calculated using Q statistic I2 . RESULTS: A total of 6 studies-comprised of 59% males-were included in our analysis, which showed an increased combined risk of development of aortic aneurysm and aortic dissection with quinolone exposure when compared with controls (relative risk [RR] = 2.11; 95% CI, 1.62 - 2.75; I2 = 83.700). Individual relative risk for aortic aneurysm (RR = 2.83; 95% CI, 2.02 - 3.95, I2 = 89.150) and aortic dissection (RR = 1.99; 95% CI, 1.23 - 3.06; I22 = 71.33) also were significantly increased. CONCLUSION: Compared to other antibiotics, the use of fluoroquinolones was associated with a significantly higher risk of aortic aneurysm and dissection combined.

The Struggling Infectious Diseases Fellow: Remediation Challenges and Opportunities.

Remediation of struggling learners is a challenge faced by all educators. In recognition of this reality, and in light of contemporary challenges facing infectious diseases (ID) fellowship program directors, the Infectious Diseases Society of America Training Program Directors' Committee focused the 2018 National Fellowship Program Directors' Meeting at IDWeek on "Remediation of the Struggling Fellow." Small group discussions addressed 7 core topics, including feedback and evaluations, performance management and remediation, knowledge deficits, fellow well-being, efficiency and time management, teaching skills, and career development. This manuscript synthesizes those discussions around a competency-based framework to provide program directors and other educators with a roadmap for addressing common contemporary remediation challenges.

Stenotrophomonas maltophilia Endocarditis of an Implantable Cardioverter Defibrillator Lead.

Stenotrophomonas maltophilia (S. maltophilia) is a nosocomial pathogen and a rare cause of infective endocarditis (IE). Given the intrinsic resistance to many classes of antibiotics, IE due to S. maltophilia carries significant morbidity and mortality among the cases described. Prompt identification of risk factors, particularly the use of medical devices, is necessary for the timely identification of this organism and prompt medical management. We report a case of an implantable cardioverter defibrillator (ICD) lead associated IE due to S. maltophilia and discuss the diagnosis, treatment and outcomes in relation to existing evidence.

Effect of Frequency of Changing Point-of-Use Reminder Signs on Health Care Worker Hand Hygiene Adherence: A Cluster Randomized Clinical Trial.

Importance: Although hand hygiene (HH) is considered the most effective strategy for preventing hospital-acquired infections, HH adherence rates remain poor. Objective: To examine whether the frequency of changing reminder signs affects HH adherence among health care workers. Design, Setting, and Participants: This cluster randomized clinical trial in 9 US Department of Veterans Affairs acute care hospitals randomly assigned 58 inpatient units to 1 of 3 schedules for changing signs designed to promote HH adherence among health care workers: (1) no change; (2) weekly; and (3) monthly. Hand hygiene rates among health care workers were documented at entry and exit to patient rooms during the baseline period from October 1, 2014, to March 31, 2015, of normal signage and throughout the intervention period of June 8, 2015, to December 28, 2015. Data analyses were conducted in April 2018. Interventions: Hospital units were randomly assigned into 3 groups: (1) no sign changes throughout the intervention period, (2) signs changed weekly, and (3) signs changed monthly. Main Outcomes and Measures: Hand hygiene adherence as measured by covert observation. Interrupted time series analysis was used to examine changes in HH adherence from baseline through the intervention period by group. Results: Among 58 inpatient units, 19 units were assigned to the no change group, 19 units were assigned to the weekly change group, and 20 units were assigned to the monthly change group. During the baseline period, 9755 HH opportunities were observed at room entry and 10 095 HH opportunities were observed at room exit. During the intervention period, a total of 15 855 HH opportunities were observed at room entry, and 16 360 HH opportunities were observed at room exit. Overall HH adherence did not change from baseline compared with the intervention period at either room entry (4770 HH events [48.9%] vs 3057 HH events [50.1%]; P = .14) or exit (6439 HH events [63.8%] vs 4087 HH events [65.2%]; P = .06). In units that changed signs weekly, HH adherence declined from baseline at room entry (-1.9% [95% CI, -2.7% to -0.8%] per week; P < .001) and exit (-0.8% [95% CI, -1.5% to 0.1%] per week; P = .02). No significant changes in HH adherence were observed in other groups. Conclusions and Relevance: The frequency of changing reminder signs had no effect on HH rates overall. Units assigned to change signs most frequently demonstrated worsening adherence. Considering the abundance of signs in the acute care environment, the frequency of changing signs did not appear to provide a strong enough cue by itself to promote behavioral change.

Role of environmental surveillance in determining the risk of hospital-acquired legionellosis: a national surveillance study with clinical correlations.

OBJECTIVE: Hospital-acquired Legionella pneumonia has a fatality rate of 28%, and the source is the water distribution system. Two prevention strategies have been advocated. One approach to prevention is clinical surveillance for disease without routine environmental monitoring. Another approach recommends environmental monitoring even in the absence of known cases of Legionella pneumonia. We determined the Legionella colonization status of water systems in hospitals to establish whether the results of environmental surveillance correlated with discovery of disease. None of these hospitals had previously experienced endemic hospital-acquired Legionella pneumonia. DESIGN: Cohort study. SETTING: Twenty US hospitals in 13 states. INTERVENTIONS: Hospitals performed clinical and environmental surveillance for Legionella from 2000 through 2002. All specimens were shipped to the Special Pathogens Laboratory at the Veterans Affairs Pittsburgh Medical Center. RESULTS: Legionella pneumophila and Legionella anisa were isolated from 14 (70%) of 20 hospital water systems. Of 676 environmental samples, 198 (29%) were positive for Legionella species. High-level colonization of the water system (30% or more of the distal outlets were positive for L. pneumophila) was demonstrated for 6 (43%) of the 14 hospitals with positive findings. L. pneumophila serogroup 1 was detected in 5 of these 6 hospitals, whereas 1 hospital was colonized with L. pneumophila serogroup 5. A total of 633 patients were evaluated for Legionella pneumonia from 12 (60%) of the 20 hospitals: 377 by urinary antigen testing and 577 by sputum culture. Hospital-acquired Legionella pneumonia was identified in 4 hospitals, all of which were hospitals with L. pneumophila serogroup 1 found in 30% or more of the distal outlets. No cases of disease due to other serogroups or species (L. anisa) were identified. CONCLUSION: Environmental monitoring followed by clinical surveillance was successful in uncovering previously unrecognized cases of hospital-acquired Legionella pneumonia.

Other Slow-Growing Nontuberculous Mycobacteria.

The list of clinically important slow-growing nontuberculous mycobacteria (NTM) continues to expand as new species are identified and older ones are found to be pathogenic. Based on pigment production, the strains may be classified as photochromogenic, scotochromogenic, or unpigmented. Some of these organisms are not newly discovered but have heretofore been considered virtually nonpathogenic. Previously, many were regarded as contaminants when isolated from clinical specimens. Ubiquitous in nature, many NTM have been isolated from groundwater or tap water, soil, house dust, domestic and wild animals, and birds. Most infections result from inhalation or direct inoculation from environmental sources. They are not spread from person to person. The infections may be localized or disseminated. In most cases, the optimal regimen or duration of therapy has not been firmly established. The results of in vitro susceptibility testing may be used to select a therapeutic regimen. Many experts recommend clarithromycin with companion drugs such as rifampin and ethambutol for most, but not all, slowly growing species. Aminoglycosides, clofazimine, fluoroquinolones, linezolid, pyrazinamide, or trimethoprim-sulfamethoxazole also may be effective against some strains. Immunocompetent patients with clinically significant infections with NTM usually should receive 18 to 24 months of therapy. Infected immunocompromised patients, particularly those with disseminated infection, probably should receive therapy as long as their immune systems remain impaired. Some of the species discussed include Mycobacterium alsiense, M. celatum, M. gordonae, M. haemophilum, M. kyorinense, M. malmoense, M. simiae complex, M. szulgai, M. terrae complex, M. ulcerans, and M. xenopi.

A Profile of Patients Who Fail to Keep Appointments in a Veterans Affairs Primary Care Clinic.

BACKGROUND: Missed medical appointments ("no-shows") affect both staff and other patients who are unable to make timely appointments. No-shows can be prevented through interventions that target those most at risk to miss appointments. Young age, low socioeconomic status, a history of missed appointments, psychosocial problems, and longer wait times are some predictors that previously have been associated with higher no-show rates. OBJECTIVE: To determine predictors for outpatient appointment no-shows in primary care clinics of the Veterans Affairs Nebraska-Western Iowa Health Care System. METHODS: The study included 69,908 noncancelled primary care appointments between January 1, 2012 and December 31, 2013 among patients residing in ZIP codes within the Veterans Affairs Nebraska-Western Iowa Health Care System Service Area. Age, sex, race, presence of a mental health diagnosis, previous no-show rate in the past 2 years, appointment wait time, distance to clinic, and neighborhood deprivation index were extracted or measured for each patient. RESULTS: In log-binomial models accounting for clustering by ZIP code, the strongest predictors of no-shows were age between 20 and 39 (OR compared to 60+: 3.87, 95% CI, 3.48-4.31) or between 40 and 59 (OR compared to 60+: 2.23, 95% CI, 2.05-2.43), black (OR compared to white: 2.14, 95% CI, 1.98-2.31) or other nonwhite race (OR compared to white: 1.35, 95% CI, 1.17- 1.56), male sex (OR compared to female: 1.30, 95% CI, 1.16-1.45), and presence versus absence of mental health diagnosis (OR: 1.16, 95% CI, 1.09-1.24). CONCLUSION: These findings show that individuals who are younger, nonwhite, male, or have been diagnosed with mental health issues are more likely to no-show. Interventions to improve compliance could be targeted at these individuals in order to decrease the burden of no-shows on health care systems.

Education and Communication in an Interprofessional Antimicrobial Stewardship Program.

CONTEXT: Interprofessional education/interprofessional practice (IPE/IPP) is an essential component in medical education and training. A collaborative interprofessional team environment ensures optimal patient-centered care. OBJECTIVE: To describe the implementation of 2 interprofessional antimicrobial stewardship program (ASP) teams using IPE/IPP and to assess the acceptance rate by the primary medical and surgical teams of ASP recommendations for antimicrobial interventions. METHODS: A business plan for the ASP was approved at 2 academic medical centers used for the present study. During a 3-year study period, 2 interprofessional ASP teams included an attending physician specializing in infectious disease (ID), an ID physician fellow, an ASP pharmacist, physician residents, medical students, pharmacy residents, and pharmacy students. Educational seminars were presented for all adult-admitting physicians to discuss the need for the ASP and the prospective audit and feedback process. Cases were presented for discussion during ASP/ID rounds and recommendations were agreed upon by the ASP team. A motivational interviewing face-to-face technique was frequently used to convey the ASP team recommendation to the primary medical or surgical team in a noncoercive and educational manner. The ASP team recommendations for ASP interventions were documented in the medical records. RESULTS: The overall acceptance rate of recommendations by the primary medical and surgical teams were greater than 90% (2051 of 2266). The most frequent interventions provided were streamline therapy (601), route of administration change (452), bug-drug mismatch (190), and discontinuation of therapy (179). Route of administration change was also the most frequently accepted intervention (96%). CONCLUSIONS: The motivational face-to-face communication technique was particularly useful in conveying ASP team member recommendations to the primary medical or surgical teams. Communicating recommendations as a multidisciplinary team in an educational manner seems to have resulted in to greater acceptance of recommendations.

Benefits and harms of doxycycline treatment for Gulf War veterans' illnesses: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: It has been hypothesized that certain Mycoplasma species may cause Gulf War veterans' illnesses (GWVIs), chronic diseases characterized by pain, fatigue, and cognitive symptoms, and that affected patients may benefit from doxycycline treatment. OBJECTIVE: To determine whether a 12-month course of doxycycline improves functional status in Gulf War veterans with GWVIs. DESIGN: A randomized, double-blind, placebo-controlled clinical trial with 12 months of treatment and 6 additional months of follow-up. SETTING: 26 U.S. Department of Veterans Affairs and 2 U.S. Department of Defense medical centers. PARTICIPANTS: 491 deployed Gulf War veterans with GWVIs and detectable Mycoplasma DNA in the blood. INTERVENTION: Doxycycline, 200 mg, or matching placebo daily for 12 months. MEASUREMENTS: The primary outcome was the proportion of participants who improved more than 7 units on the Physical Component Summary score of the Veterans Short Form-36 General Health Survey 12 months after randomization. Secondary outcomes were measures of pain, fatigue, and cognitive function and change in positivity for Mycoplasma species at 6, 12, and 18 months after randomization. RESULTS: No statistically significant differences were found between the doxycycline and placebo groups for the primary outcome measure (43 of 238 participants [18.1%] vs. 42 of 243 participants [17.3%]; difference, 0.8 percentage point [95% CI, -6.5 to 8.0 percentage points]; P > 0.2) or for secondary outcome measures at 1 year. In addition, possible differences in outcomes at 3 and 6 months were not apparent at 9 or 18 months. Participants in the doxycycline group had a higher incidence of nausea and photosensitivity. LIMITATIONS: Adherence to treatment after 6 months was poor. CONCLUSION: Long-term treatment with doxycycline did not improve outcomes of GWVIs at 1 year.

Limited impact of sustained simple feedback based on soap and paper towel consumption on the frequency of hand washing in an adult intensive care unit.

OBJECTIVE: To determine whether hand washing would increase with sustained feedback based on measurements of soap and paper towel consumption. DESIGN: Prospective trial with a nonequivalent control group. SETTING: Open multibed rooms in the Omaha Veterans Affairs Medical Center's Surgical Intensive Care Unit (SICU) and Medical Intensive Care Unit (MICU). SUBJECTS: Unit staff. INTERVENTION: Every weekday from May 26 through December 8, 1998, we recorded daytime soap and paper towel consumption, nurse staffing, and occupied beds in the SICU (intervention unit) and the MICU (control unit) and used these data to calculate estimated hand washing episodes (EHWEs), EHWEs per occupied bed per hour, and patient-to-nurse ratios. In addition, from May 26 through June 26 (baseline period) and from November 2 through December 8 (follow-up period), live observers stationed daily for random 4-hour intervals in the MICU and the SICU counted actual hand washing episodes (CHWEs). The intervention consisted of posting in the SICU, but not in the MICU, a graph showing the weekly EHWEs per occupied bed per hour for the preceding 5 weeks. RESULTS: Directly counted hand washing fell in the SICU from a baseline of 2.68+/-0.72 (mean +/- standard deviation) episodes per occupied bed per hour to 1.92+/-1.35 in the follow-up period. In the MICU, episodes fell from 2.58+/-0.95 (baseline) to 1.74+/-0.69. In the MICU, the withdrawal of live observers was associated with a decrease in estimated episodes from 1.36+/-0.49 at baseline to 1.01+/-0.36, with a return to 1.16+/-0.50 when the observers returned. In the SICU, a similar decrease did not persist throughout a period of feedback. Estimated hand washing correlated negatively with the patient-to-nurse ratio (r = -0.35 for the MICU, r = -0.46 for the SICU). CONCLUSIONS: Sustained feedback on hand washing failed to produce a sustained improvement. Live observers were associated with increased hand washing, even when they did not offer feedback. Hand washing decreased when the patient-to-nurse ratio increased.
