Decolonization to Reduce Postdischarge Infection Risk among MRSA Carriers.

BACKGROUND: Hospitalized patients who are colonized with methicillin-resistant Staphylococcus aureus (MRSA) are at high risk for infection after discharge. METHODS: We conducted a multicenter, randomized, controlled trial of postdischarge hygiene education, as compared with education plus decolonization, in patients colonized with MRSA (carriers). Decolonization involved chlorhexidine mouthwash, baths or showers with chlorhexidine, and nasal mupirocin for 5 days twice per month for 6 months. Participants were followed for 1 year. The primary outcome was MRSA infection as defined according to Centers for Disease Control and Prevention (CDC) criteria. Secondary outcomes included MRSA infection determined on the basis of clinical judgment, infection from any cause, and infection-related hospitalization. All analyses were performed with the use of proportional-hazards models in the per-protocol population (all participants who underwent randomization, met the inclusion criteria, and survived beyond the recruitment hospitalization) and as-treated population (participants stratified according to adherence). RESULTS: In the per-protocol population, MRSA infection occurred in 98 of 1063 participants (9.2%) in the education group and in 67 of 1058 (6.3%) in the decolonization group; 84.8% of the MRSA infections led to hospitalization. Infection from any cause occurred in 23.7% of the participants in the education group and 19.6% of those in the decolonization group; 85.8% of the infections led to hospitalization. The hazard of MRSA infection was significantly lower in the decolonization group than in the education group (hazard ratio, 0.70; 95% confidence interval [CI], 0.52 to 0.96; P=0.03; number needed to treat to prevent one infection, 30; 95% CI, 18 to 230); this lower hazard led to a lower risk of hospitalization due to MRSA infection (hazard ratio, 0.71; 95% CI, 0.51 to 0.99). The decolonization group had lower likelihoods of clinically judged infection from any cause (hazard ratio, 0.83; 95% CI, 0.70 to 0.99) and infection-related hospitalization (hazard ratio, 0.76; 95% CI, 0.62 to 0.93); treatment effects for secondary outcomes should be interpreted with caution owing to a lack of prespecified adjustment for multiple comparisons. In as-treated analyses, participants in the decolonization group who adhered fully to the regimen had 44% fewer MRSA infections than the education group (hazard ratio, 0.56; 95% CI, 0.36 to 0.86) and had 40% fewer infections from any cause (hazard ratio, 0.60; 95% CI, 0.46 to 0.78). Side effects (all mild) occurred in 4.2% of the participants. CONCLUSIONS: Postdischarge MRSA decolonization with chlorhexidine and mupirocin led to a 30% lower risk of MRSA infection than education alone.

Staphylococcus epidermidis Bacteremia Induces Brain Injury in Neonatal Mice via Toll-like Receptor 2-Dependent and -Independent Pathways.

BACKGROUND: Staphylococcus epidermidis causes late-onset sepsis in preterm infants. Staphylococcus epidermidis activates host responses in part via Toll-like receptor 2 (TLR2). Epidemiologic studies link bacteremia and neonatal brain injury, but direct evidence is lacking. METHODS: Wild-type and TLR2-deficient (TLR2-/-) mice were injected intravenously with S. epidermidis at postnatal day 1 prior to measuring plasma and brain cytokine and chemokine levels, bacterial clearance, brain caspase-3 activation, white/gray matter volume, and innate transcriptome. RESULTS: Staphylococcus epidermidis bacteremia spontaneously resolved over 24 hours without detectable bacteria in the cerebrospinal fluid (CSF). TLR2-/- mice demonstrated delayed S. epidermidis clearance from blood, spleen, and liver. Staphylococcus epidermidis increased the white blood cell count in the CSF, increased interleukin 6, interleukin 12p40, CCL2, and CXCL1 concentrations in plasma; increased the CCL2 concentration in the brain; and caused rapid (within 6 hours) TLR2-dependent brain activation of caspase-3 and TLR2-independent white matter injury. CONCLUSIONS: Staphylococcus epidermidis bacteremia, in the absence of bacterial entry into the CSF, impairs neonatal brain development. Staphylococcus epidermidis bacteremia induced both TLR2-dependent and -independent brain injury, with the latter occurring in the absence of TLR2, a condition associated with an increased bacterial burden. Our study indicates that the consequences of transient bacteremia in early life may be more severe than commonly appreciated, and our findings may inform novel approaches to reduce bacteremia-associated brain injury.

Incidence and Patterns of Extended-Course Antibiotic Therapy in Patients Evaluated for Lyme Disease.

BACKGROUND: Most patients with Lyme disease (LD) can be treated effectively with 2-4 weeks of antibiotics. The Infectious Disease Society of America guidelines do not currently recommend extended treatment even in patients with persistent symptoms. METHODS: To estimate the incidence of extended use of antibiotics in patients evaluated for LD, we retrospectively analyzed claims from a nationwide US health insurance plan in 14 high-prevalence states over 2 periods: 2004-2006 and 2010-2012. RESULTS: As measured by payer claims, the incidence of extended antibiotic therapy among patients evaluated for LD was higher in 2010-2012 (14.72 per 100 000 person-years; n = 684) than in 2004-2006 (9.94 per 100 000 person-years; n = 394) (P < .001). Among these patients, 48.8% were treated with ≥2 antibiotics in 2010-2012 and 29.9% in 2004-2006 (P < .001). In each study period, a distinct small group of providers (roughly 3%-4%) made the diagnosis in >20% of the patients who were evaluated for LD and prescribed extended antibiotic treatment. CONCLUSIONS: Insurance claims data suggest that the use of extended courses of antibiotics and multiple antibiotics in the treatment of LD has increased in recent years.

Effect of nonpayment for preventable infections in U.S. hospitals.

BACKGROUND: In October 2008, the Centers for Medicare and Medicaid Services (CMS) discontinued additional payments for certain hospital-acquired conditions that were deemed preventable. The effect of this policy on rates of health care-associated infections is unknown. METHODS: Using a quasi-experimental design with interrupted time series with comparison series, we examined changes in trends of two health care-associated infections that were targeted by the CMS policy (central catheter-associated bloodstream infections and catheter-associated urinary tract infections) as compared with an outcome that was not targeted by the policy (ventilator-associated pneumonia). Hospitals participating in the National Healthcare Safety Network and reporting data on at least one health care-associated infection before the onset of the policy were eligible to participate. Data from January 2006 through March 2011 were included. We used regression models to measure the effect of the policy on changes in infection rates, adjusting for baseline trends. RESULTS: A total of 398 hospitals or health systems contributed 14,817 to 28,339 hospital unit-months, depending on the type of infection. We observed decreasing secular trends for both targeted and nontargeted infections long before the policy was implemented. There were no significant changes in quarterly rates of central catheter-associated bloodstream infections (incidence-rate ratio in the postimplementation vs. preimplementation period, 1.00; P=0.97), catheter-associated urinary tract infections (incidence-rate ratio, 1.03; P=0.08), or ventilator-associated pneumonia (incidence-rate ratio, 0.99; P=0.52) after the policy implementation. Our findings did not differ for hospitals in states without mandatory reporting, nor did it differ according to the quartile of percentage of Medicare admissions or hospital size, type of ownership, or teaching status. CONCLUSIONS: We found no evidence that the 2008 CMS policy to reduce payments for central catheter-associated bloodstream infections and catheter-associated urinary tract infections had any measurable effect on infection rates in U.S. hospitals.

Intervention to reduce transmission of resistant bacteria in intensive care.

BACKGROUND: Intensive care units (ICUs) are high-risk settings for the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE). METHODS: In a cluster-randomized trial, we evaluated the effect of surveillance for MRSA and VRE colonization and of the expanded use of barrier precautions (intervention) as compared with existing practice (control) on the incidence of MRSA or VRE colonization or infection in adult ICUs. Surveillance cultures were obtained from patients in all participating ICUs; the results were reported only to ICUs assigned to the intervention. In intervention ICUs, patients who were colonized or infected with MRSA or VRE were assigned to care with contact precautions; all the other patients were assigned to care with universal gloving until their discharge or until surveillance cultures obtained at admission were reported to be negative. RESULTS: During a 6-month intervention period, there were 5434 admissions to 10 intervention ICUs, and 3705 admissions to 8 control ICUs. Patients who were colonized or infected with MRSA or VRE were assigned to barrier precautions more frequently in intervention ICUs than in control ICUs (a median of 92% of ICU days with either contact precautions or universal gloving [51% with contact precautions and 43% with universal gloving] in intervention ICUs vs. a median of 38% of ICU days with contact precautions in control ICUs, P<0.001). In intervention ICUs, health care providers used clean gloves, gowns, and hand hygiene less frequently than required for contacts with patients assigned to barrier precautions; when contact precautions were specified, gloves were used for a median of 82% of contacts, gowns for 77% of contacts, and hand hygiene after 69% of contacts, and when universal gloving was specified, gloves were used for a median of 72% of contacts and hand hygiene after 62% of contacts. The mean (±SE) ICU-level incidence of events of colonization or infection with MRSA or VRE per 1000 patient-days at risk, adjusted for baseline incidence, did not differ significantly between the intervention and control ICUs (40.4±3.3 and 35.6±3.7 in the two groups, respectively; P=0.35). CONCLUSIONS: The intervention was not effective in reducing the transmission of MRSA or VRE, although the use of barrier precautions by providers was less than what was required.

Developing a pathway for high-value, patient-centered total joint arthroplasty.

BACKGROUND: Total joint arthroplasty (TJA) is one of the most widely performed elective procedures; however, there are wide variations in cost and quality among facilities where the procedure is performed. QUESTIONS/PURPOSES: The purposes of this study were to (1) develop a generalizable clinical care pathway for primary TJA using inputs from clinical, academic, and patient stakeholders; and (2) identify system- and patient-level processes to provide safe, effective, efficient, and patient-centered care for patients undergoing TJA. METHODS: We used a combination of quantitative and qualitative methods to design a care pathway that spans 14 months beginning with the presurgical office visit and concluding 12 months after discharge. We derived care suggestions from interviews with 16 hospitals selected based on readmission rates, cost, and quality (n = 10) and author opinion (n = 6). A 32-member multistakeholder panel refined the pathway during a 1-day workshop. Participants were selected based on leadership in orthopaedic (n = 4) and anesthesia (n = 1) specialty societies; involvement in organizations specializing in safety and high reliability care (n = 3), lean production/consumption of care (n = 3), and patient experience of care (n = 3); membership in an interdisciplinary care team of a hospital selected for interviewing (n = 8); recent receipt of a TJA (n = 1); and participation in the pathway development team (n = 9). RESULTS: The care pathway includes 40 suggested processes to improve care, 37 techniques to reduce waste, and 55 techniques to improve communication. Central themes include standardization and process improvement, interdisciplinary communication and collaboration, and patient/family engagement and education. Selected recommendations include standardizing care protocols and staff roles; aligning information flow with patient and process flow; identifying a role accountable for care delivery and communication; managing patient expectations; and stratifying patients into the most appropriate care level. CONCLUSIONS: We developed a multidisciplinary clinical care pathway for patients undergoing TJA based on principles of high-value care. The pathway is ready for clinical testing and context-specific adaptation. LEVEL OF EVIDENCE: Level V, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Temporal trends in rates of patient harm resulting from medical care.

BACKGROUND: In the 10 years since publication of the Institute of Medicine's report To Err Is Human, extensive efforts have been undertaken to improve patient safety. The success of these efforts remains unclear. METHODS: We conducted a retrospective study of a stratified random sample of 10 hospitals in North Carolina. A total of 100 admissions per quarter from January 2002 through December 2007 were reviewed in random order by teams of nurse reviewers both within the hospitals (internal reviewers) and outside the hospitals (external reviewers) with the use of the Institute for Healthcare Improvement's Global Trigger Tool for Measuring Adverse Events. Suspected harms that were identified on initial review were evaluated by two independent physician reviewers. We evaluated changes in the rates of harm, using a random-effects Poisson regression model with adjustment for hospital-level clustering, demographic characteristics of patients, hospital service, and high-risk conditions. RESULTS: Among 2341 admissions, internal reviewers identified 588 harms (25.1 harms per 100 admissions; 95% confidence interval [CI], 23.1 to 27.2) [corrected]. Multivariate analyses of harms identified by internal reviewers showed no significant changes in the overall rate of harms per 1000 patient-days (reduction factor, 0.99 per year; 95% CI, 0.94 to 1.04; P=0.61) or the rate of preventable harms. There was a reduction in preventable harms identified by external reviewers that did not reach statistical significance (reduction factor, 0.92; 95% CI, 0.85 to 1.00; P=0.06), with no significant change in the overall rate of harms (reduction factor, 0.98; 95% CI, 0.93 to 1.04; P=0.47). CONCLUSIONS: In a study of 10 North Carolina hospitals, we found that harms remain common, with little evidence of widespread improvement. Further efforts are needed to translate effective safety interventions into routine practice and to monitor health care safety over time. (Funded by the Rx Foundation.).

Health information management and perceptions of the quality of care for children with tracheotomy: a qualitative study.

BACKGROUND: Children with tracheotomy receive health care from an array of providers within various hospital and community health system sectors. Previous studies have highlighted substandard health information exchange between families and these sectors. The aim of this study was to investigate the perceptions and experiences of parents and providers with regard to health information management, care plan development and coordination for children with tracheotomy, and strategies to improve health information management for these children. METHODS: Individual and group interviews were performed with eight parents and fifteen healthcare (primary and specialty care, nursing, therapist, equipment) providers of children with tracheotomy. The primary tracheotomy-associated diagnoses for the children were neuromuscular impairment (n = 3), airway anomaly (n = 2) and chronic lung disease (n = 3). Two independent reviewers conducted deep reading and line-by-line coding of all transcribed interviews to discover themes associated with the objectives. RESULTS: Children with tracheotomy in this study had healthcare providers with poorly defined roles and responsibilities who did not actively communicate with one another. Providers were often unsure where to find documentation relating to a child's tracheotomy equipment settings and home nursing orders, and perceived that these situations contributed to medical errors and delayed equipment needs. Parents created a home record that was shared with multiple providers to track the care that their children received but many considered this a burden better suited to providers. Providers benefited from the parent records, but questioned their accuracy regarding critical tracheotomy care plan information such as ventilator settings. Parents and providers endorsed potential improvement in this environment such as a comprehensive internet-based health record that could be shared among parents and providers, and between various clinical sites. CONCLUSIONS: Participants described disorganized tracheotomy care and health information mismanagement that could help guide future investigations into the impact of improved health information systems for children with tracheotomy. Strategies with the potential to improve tracheotomy care delivery could include defined roles and responsibilities for tracheotomy providers, and improved organization and parent support for maintenance of home-based tracheotomy records with web-based software applications, personal health record platforms and health record data authentication techniques.

Impact of the ventilator bundle on ventilator-associated pneumonia in intensive care unit.

OBJECTIVE: The ventilator bundle is being promoted to prevent adverse events in ventilated patients including ventilator-associated pneumonia (VAP). We aimed to: (i) examine adoption of the ventilator bundle elements; (ii) determine effectiveness of individual elements and setting characteristics in reducing VAP; (iii) determine effectiveness of two infection-specific elements on reducing VAP; and, (iv) assess crossover effects of complying with VAP elements on central line-associated bloodstream infections. DESIGN: Cross-sectional survey. SETTING: Four hundred and fifteen ICUs from 250 US hospitals. PARTICIPANTS: Managers/directors of infection prevention and control departments. INTERVENTIONS: Adoption and compliance with ventilator bundle elements. MAIN OUTCOME MEASURES: VAP rates. RESULTS: The mean VAP rate was 2.7/1000 ventilator days. Two-thirds (n = 284) reported presence of the full ventilator bundle policy. However, only 66% (n = 188/284) monitored implementation; of those, 39% (n = 73/188) reported high compliance. Only when an intensive care unit (ICU) had a policy, monitored compliance and achieved high compliance were VAP rates lower. Compliance with individual elements or just one of two infection-related element had no impact on VAP (ß = -0.79, P= 0.15). There was an association between complying with two infection elements and lower rates (ß = -1.81, P< 0.01). There were no crossover effects. Presence of a full-time hospital epidemiologist (HE) was significantly associated with lower VAP rates (ß = -3.62, P< 0.01). CONCLUSIONS: The ventilator bundle was frequently present but not well implemented. Individual elements did not appear effective; strict compliance with infection elements was needed. Efforts to prevent VAP may be successful in settings of high levels of compliance with all infection-specific elements and in settings with full-time HEs.

Impact of enhanced infection control at 2 neonatal intensive care units in the Philippines.

BACKGROUND: The growing burden of neonatal mortality associated with hospital-acquired neonatal sepsis in the developing world creates an urgent need for cost-effective infection-control measures in resource-limited settings. METHODS: Using a before-and-after comparison design, we measured how rates of staff hand-hygiene compliance, colonization with drug-resistant pathogens (defined as ceftazidime- and/or gentamicin-resistant gram-negative bacilli and drug-resistant gram-positive cocci), bacteremia, and overall mortality changed after the introduction of a simplified package of infection-control measures at 2 neonatal intensive care units (NICUs) in Manila, The Philippines. RESULTS: Of all 1827 neonates admitted to the NICU, 561 (30.7%) arrived from delivery already colonized with drug-resistant bacteria. Of the 1266 neonates who were not already colonized, 578 (45.6%) became newly colonized with drug-resistant bacteria. Of all 1827 neonates, 358 (19.6%) became bacteremic (78.2% were infected with gram-negative bacilli) and 615 (33.7%) died. Of 2903 identified drug-resistant colonizing bacteria, 85% were drug-resistant gram-negative bacilli (predominantly Klebsiella species, Pseudomonas species, and Acinetobacter species) and 14% were methicillin-resistant Staphylococcus aureus. Contrasting the control period with the intervention period at each NICU revealed that staff hand-hygiene compliance improved (NICU 1: relative risk, 1.3; 95% confidence interval 1.1-1.5; NICU 2: relative risk, 1.6; 95% confidence interval, 1.4-2.0) and that overall mortality decreased (NICU 1: relative risk, 0.5; 95% confidence interval, 0.4-0.6; NICU 2: relative risk, 0.8; 95% confidence interval, 0.7-0.9). However, rates of colonization with drug-resistant pathogens and of sepsis did not change significantly at either NICU. DISCUSSION: Nosocomial transmission of drug-resistant pathogens was intense at these 2 NICUs in The Philippines; transmission involved mostly drug-resistant gram-negative bacilli. Infection-control interventions are feasible and are possibly effective in resource-limited hospital settings.

Controlled evaluation of Bactec Peds Plus/F and Bactec lytic/10 anaerobic/F media for isolation of Salmonella enterica serovars typhi and paratyphi A from blood.

We compared anaerobic lytic (AL) and pediatric aerobic resin-containing (Peds Plus/F) blood culture media for the isolation of Salmonella enterica serotype Typhi or Paratyphi A from children. The yields from AL and Peds Plus/F media were the same with equal volumes of blood, but recovery was faster from AL medium than Peds Plus/F medium (10.7 and 16.4 h, respectively) (P < 0.001).

Parent-driven technology for decision support in pediatric emergency care.

BACKGROUND: A quasi-experimental intervention study composed of control and intervention periods was conducted to determine if a parent-driven health information technology influenced completeness of documentation and adherence to evidence-based emergency care for children. METHODS: Structured chart abstraction was used to assess documentation and correctness of clinical actions at test ordering, medication prescribed for disease, and medication ordered for pain in a tertiary care pediatric emergency department and a suburban general emergency department. During the intervention periods, parents of children who presented with complaints related to otitis media, urinary tract infection, head trauma, or asthma entered data into a health information technology (ParentLink), which produced treatment plans in the context of evidence-based guidelines. RESULTS: Of 1,410 subjects analyzed, 1,072 (76%) were assigned to one of four disease categories: urinary tract infection (22%), otitis media (20%), asthma (11%) and head trauma (47%). During ParentLink use, documentation of pain significantly improved (28% incomplete [control] versus 15% [intervention], p = .003). Incorrect actions for pain treatment decreased, but not significantly (33% [control] versus 24% [intervention], p = .13). ParentLink did not influence actions for test ordering or prescribing for disease. DISCUSSION: Parent-driven health information technology intended to translate parents' knowledge into clinical practice and to support evidence-based care suggested a trend toward modest impact on pain management but did not demonstrate broad effects across diseases or care processes. The emergence and proliferation of personally controlled health records (PCHRs) presents opportunities for patients and parents to control their medical profiles. Although ParentLink is not a comprehensive PCHR, it represents a step in incorporating parent-derived information into medical decision making.

The impact of measurement changes on evaluating hospital performance: The case of catheter-associated urinary tract infections.

Catheter-associated urinary tract infections in 592 hospitals immediately declined after federal value-based incentive program implementation, but this was fully attributable to a concurrent surveillance case definition revision. Post revision, more hospitals had favorable standardized infection ratios, likely leading to artificial inflation of their performance scores unrelated to changes in patient safety.

A Collaborative Multicenter QI Initiative to Improve Antibiotic Stewardship in Newborns.

OBJECTIVES: To determine if NICU teams participating in a multicenter quality improvement (QI) collaborative achieve increased compliance with the Centers for Disease Control and Prevention (CDC) core elements for antibiotic stewardship and demonstrate reductions in antibiotic use (AU) among newborns. METHODS: From January 2016 to December 2017, multidisciplinary teams from 146 NICUs participated in Choosing Antibiotics Wisely, an Internet-based national QI collaborative conducted by the Vermont Oxford Network consisting of interactive Web sessions, a series of 4 point-prevalence audits, and expert coaching designed to help teams test and implement the CDC core elements of antibiotic stewardship. The audits assessed unit-level adherence to the CDC core elements and collected patient-level data about AU. The AU rate was defined as the percentage of infants in the NICU receiving 1 or more antibiotics on the day of the audit. RESULTS: The percentage of NICUs implementing the CDC core elements increased in each of the 7 domains (leadership: 15.4%-68.8%; accountability: 54.5%-95%; drug expertise: 61.5%-85.1%; actions: 21.7%-72.3%; tracking: 14.7%-78%; reporting: 6.3%-17.7%; education: 32.9%-87.2%; P < .005 for all measures). The median AU rate decreased from 16.7% to 12.1% (P for trend < .0013), a 34% relative risk reduction. CONCLUSIONS: NICU teams participating in this QI collaborative increased adherence to the CDC core elements of antibiotic stewardship and achieved significant reductions in AU.

Risk factors in preventable adverse drug events in pediatric outpatients.

OBJECTIVE: To determine whether there are racial/ethnic, socioeconomic, parental linguistic, or parental educational disparities in children who experienced an adverse drug event (ADE) in the ambulatory setting. STUDY DESIGN: We conducted a prospective cohort study of pediatric patients <21 years seen during 2-month study periods from July 2002 to April 2003 at 6 office practices in Boston. The primary outcome measure was ADEs. Descriptive analysis of patient characteristics and types of ADEs experienced was followed by multivariate analysis to determine risk factors associated with presence of a preventable ADE. RESULTS: A total of 1689 patients receiving 2155 prescriptions were analyzed via a survey and chart review. Overall, 242 children (14%) experienced an ADE, of which 55 (23%) had a preventable ADE and 186 (77%) had a non-preventable ADE. In multivariate analysis, children with multiple prescriptions (odds ratio, 1.46; 95% CI, 1.01-2.11) were at increased risk of having a preventable ADE, controlling for parental education, racial/ethnic, English proficiency, practice type, and duration of care. CONCLUSIONS: Children with multiple prescriptions are at increased risk of having a preventable ADE. Further attention should be directed toward improved communication among healthcare providers and patients.

The Impact of the Medicaid Healthcare-Associated Condition Program on Mediastinitis Following Coronary Artery Bypass Graft.

OBJECTIVEIn 2012, the Centers for Medicare and Medicaid Services expanded a 2008 program that eliminated additional Medicare payment for mediastinitis following coronary artery bypass graft (CABG) to include Medicaid. We aimed to evaluate the impact of this Medicaid program on mediastinitis rates reported by the National Healthcare Safety Network (NHSN) compared with the rates of a condition not targeted by the program, deep-space surgical site infection (SSI) after knee replacement.DESIGNInterrupted time series with comparison group.METHODSWe included surveillance data from nonfederal acute-care hospitals participating in the NHSN and reporting CABG or knee replacement outcomes from January 2009 through June 2017. We examined the Medicaid program's impact on NHSN-reported infection rates, adjusting for secular trends. The data analysis used generalized estimating equations with robust sandwich variance estimators.RESULTSDuring the study period, 196 study hospitals reported 273,984 CABGs to the NHSN, resulting in 970 mediastinitis cases (0.35%), and 294 hospitals reported 555,395 knee replacements, with 1,751 resultant deep-space SSIs (0.32%). There was no significant change in incidence of either condition during the study. Mediastinitis models showed no effect of the 2012 Medicaid program on either secular trend during the postprogram versus preprogram periods (P=.70) or an immediate program effect (P=.83). Results were similar in sensitivity analyses when adjusting for hospital characteristics, restricting to hospitals with consistent NHSN reporting or incorporating a program implementation roll-in period. Knee replacement models also showed no program effect.CONCLUSIONSThe 2012 Medicaid program to eliminate additional payments for mediastinitis following CABG had no impact on reported mediastinitis rates.Infect Control Hosp Epidemiol 2018;39:694-700.

Prospective surveillance for surgical site infection in St. Petersburg, Russian Federation.

OBJECTIVE: To assess the risk-adjusted incidence and predictors of surgical site infections (SSIs). DESIGN: Prospective, multicenter, observational cohort study. SETTING: Seven surgical departments at 3 urban academic hospitals in St. Petersburg, Russian Federation. PATIENTS: All patients had surgery performed between January 15 and May 12, 2000. A total of 1,453 surgical procedures were followed up. Medical records were unavailable for less than 3% of all patients; patients were not excluded for any other reason. The mean patient age was 49.3 years, 61% were female, and 34% had an American Society of Anesthesiologists physical status classification (hereafter, "ASA classification") of at least 3. Surgery for 45% of the patients was emergent. RESULTS: In all, 138 patients (9.5%) developed SSI, for a rate that was approximately 3.5 times the risk-stratified rates in the United States. Male sex (odds ratio [OR], 1.54), ASA classifications of 3 (OR, 3.7) or 4 (OR, 5.0), longer duration of surgery (OR, 2.2), and wound classes of 3 (OR, 5.5) or 4 (OR, 14.3) were associated with increased SSI risk in multivariate analysis. Endoscopic surgery was associated with a lower risk of SSI (OR, 0.23). Antibiotic prophylaxis was used in 0%-33% of operations, and 69% of uninfected patients received antibiotics after the operation. CONCLUSIONS: The SSI rates are significantly higher than previously reported. Although this finding may be attributable to inadequate antibiotic prophylaxis, local infection control and surgical practices may also be contributors. Use of antibiotic prophylaxis should be encouraged and the effect of local practices further investigated. Active SSI surveillance should be expanded to other parts of the Russian Federation.

Quality of health care for children: role of health and chronic illness in inpatient care experiences.

OBJECTIVE: To assess how parent reports about the inpatient care of their children vary according to the health status of children with and without chronic conditions. DESIGN: We analyzed parent responses to the Picker Institute Pediatric Inpatient Survey. SETTING: Thirty-nine hospitals between January 1, 1997, and December 31, 1999. PARTICIPANTS: Overall, 12 562 parents of children who received inpatient care at participating hospitals. Main Outcome Measure Parent rating of overall quality of care. RESULTS: Fifty-one percent of parents reported that their child had a chronic condition. Quality-of-care ratings varied according to health status and the presence of chronic conditions. Parents of children in the worst (fair or poor) health without chronic conditions reported lower quality of care (P < .001) and more care problems (P < .001) than did those with chronic conditions. Parents of children in the best (excellent, very good, or good) health tended to rate care highly, whether or not their children had chronic conditions. In a multivariable model, the decrement in perceived quality of care associated with poorer health was greater for those without than for those with chronic conditions (P < .001). CONCLUSIONS: Although children in poor health are at risk for experiencing a lower quality of health care, parents of such children who have chronic conditions report fewer care-related problems. This may be owing to the more frequent health care interactions and better continuity of care for children with chronic conditions.
