Discordance among Belief, Practice, and the Literature in Infection Prevention in the NICU. CHILDREN 2022; 9:children9040492. [PMID: 35455536 PMCID: PMC9027430 DOI: 10.3390/children9040492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 03/29/2022] [Accepted: 03/30/2022] [Indexed: 11/16/2022]
Abstract
This study evaluates practices of infection control in the NICU as compared with the available literature. We aimed to assess providers’ awareness of their institutional policies, how strongly they believed in those policies, the correlation between institution size and policies adopted, years of experience and belief in a policy’s efficacy, and methods employed in the existing literature. An IRB-approved survey was distributed to members of the AAP Neonatal Section. A systematic review of the literature provided the domains of the survey questions. Data was analyzed as appropriate. A total of 364 providers responded. While larger NICUs were more likely to have policies, their providers are less likely to know them. When a policy is in place and it is known, providers believe in the effectiveness of that policy suggesting consensus or, at its worst, groupthink. Ultimately, practice across the US is non-uniform and policies are not always consistent with best available literature. The strength of available literature is adequate enough to provide grade B recommendations in many aspects of infection prevention. A more standardized approach to infection prevention in the NICU would be beneficial and is needed.

Abstract
OBJECTIVE To quantitatively evaluate relationships between infection preventionists (IPs) staffing levels, nursing hours, and rates of 10 types of healthcare-associated infections (HAIs). DESIGN AND SETTING An ambidirectional observation in a 528-bed teaching hospital. PATIENTS All inpatients from July 1, 2012, to February 1, 2021. METHODS Standardized US National Health Safety Network (NHSN) definitions were used for HAIs. Staffing levels were measured in full-time equivalents (FTE) for IPs and total monthly hours worked for nurses. A time-trend analysis using control charts, t tests, Poisson tests, and regression analysis was performed using Minitab and R computing programs on rates and standardized infection ratios (SIRs) of 10 types of HAIs. An additional analysis was performed on 3 stratifications: critically low (2-3 FTE), below recommended IP levels (4-6 FTE), and at recommended IP levels (7-8 FTE). RESULTS The observation covered 1.6 million patient days of surveillance. IP staffing levels fluctuated from ≤2 IP FTE (critically low) to 7-8 IP FTE (recommended levels). Periods of highest catheter-associated urinary tract infection SIRs, hospital-onset Clostridioides difficile and carbapenem-resistant Enterobacteriaceae infection rates, along with 4 of 5 types of surgical site SIRs coincided with the periods of lowest IP staffing levels and the absence of certified IPs and a healthcare epidemiologist. Central-line-associated bloodstream infections increased amid lower nursing levels despite the increased presence of an IP and a hospital epidemiologist. CONCLUSIONS Of 10 HAIs, 8 had highest incidences during periods of lowest IP staffing and experience. Some HAI rates varied inversely with levels of IP staffing and experience and others appeared to be more influenced by nursing levels or other confounders.

Abstract
BACKGROUND Given the changing nature of infection prevention and control (IPC), appropriate infection preventionist (IP) staffing needs to be established. In this study, we aimed to describe current IP staffing levels and IPC department resources in U.S. acute care hospitals. METHODS These data came from the 2015 MegaSurvey conducted by the Association of Professionals in Infection Prevention and Epidemiology. Descriptive statistics and bivariate analyses were conducted to examine differences in respondent, facility, and department characteristics by facility size (average inpatient census ≤100 vs >100). RESULTS Data from 1623 respondents were included. Most (72%) had single-site responsibilities and dedicated 76%-100% of their job to IPC (68%). The overall median IP staffing was 1.25 IPs per 100 inpatient census (interquartile range = 1.81). Almost half (46%) represented facilities with daily inpatient census ≤100; the average number of IPs in these facilities was 1.1 (standard deviation = 0.7). The reported number of IPs increased steadily with higher patient census. Significant differences were observed in IP staffing, responsibilities, and support to the IPC department between smaller and larger hospitals. CONCLUSIONS This study represents the current snapshot of IP staffing and IPC resources in acute care hospitals. Findings indicate important differences between large and small facilities in staffing and IPC resources. The field of infection prevention would benefit from a comprehensive assessment of IPC department staffing and resource needs.

Abstract
BACKGROUND Previous literature has linked the level and types of staffing of health facilities to the risk of acquiring a health care-associated infection (HAI). Investigating this relationship is challenging because of the lack of rigorous study designs and the use of varying definitions and measures of both staffing and HAIs. METHODS The objective of this study was to understand and synthesize the most recent research on the relationship of hospital staffing and HAI risk. A systematic review was undertaken. Electronic databases MEDLINE, PubMed, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for studies published between January 1, 2000, and November 30, 2015. RESULTS Fifty-four articles were included in the review. The majority of studies examined the relationship between nurse staffing and HAIs (n = 50, 92.6%) and found nurse staffing variables to be associated with an increase in HAI rates (n = 40, 74.1%). Only 5 studies addressed non-nurse staffing, and those had mixed results. Physician staffing was associated with an increased HAI risk in 1 of 3 studies. Studies varied in design and methodology, as well as in their use of operational definitions and measures of staffing and HAIs. CONCLUSION Despite the lack of consistency of the included studies, overall, the results of this systematic review demonstrate that increased staffing is related to decreased risk of acquiring HAIs. More rigorous and consistent research designs, definitions, and risk-adjusted HAI data are needed in future studies exploring this area.

Characteristics of late-onset sepsis in the NICU: does occupancy impact risk of infection? J Perinatol 2016; 36:753-7. [PMID: 27149054 DOI: 10.1038/jp.2016.71] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Revised: 03/22/2016] [Accepted: 03/28/2016] [Indexed: 01/23/2023]
Abstract
OBJECTIVE Infants in neonatal intensive care units (NICUs) are vulnerable to a variety of infections, and occupancy in the unit may correlate with risk of infection. STUDY DESIGN A retrospective cohort of infants admitted to the NICUs between 1997 and 2014. Survival analysis was used to model the relative hazard of sepsis infection in relation to two measures of occupancy: 1) the average census and 2) proportion of infants <32 weeks gestation in the unit. RESULT There were 446 (2.3%) lab-confirmed cases of bacterial or fungal sepsis, which steadily declined over time. For each additional percentage of infants <32 weeks gestation, there was an increased hazard of 2% (hazard ratio 1.02, 95% confidence interval: 1.00, 1.03) over their NICU hospitalization. Census was not associated with risk for infection. CONCLUSION During times of a greater proportion of infants <32 weeks gestation in the NICU, enhanced infection-control interventions may be beneficial to further reduce the incidence of infections.

Abstract
OBJECTIVE Assess association of NICU size, and occupancy rate and resource utilization at admission with neonatal outcome. STUDY DESIGN Retrospective cohort study of 9978 infants born at 23-32 weeks gestation and admitted to 23 tertiary-level Canadian NICUs during 2010-2012. Adjusted odds ratios (AOR) were estimated for a composite outcome of mortality/any major morbidity with respect to NICU size, occupancy rate and intensity of resource utilization at admission. RESULTS A total of 2889 (29%) infants developed the composite outcome, the odds of which were higher for 16-29, 30-36 and >36-bed NICUs compared with <16-bed NICUs (AOR (95% CI): 1.47 (1.25-1.73); 1.49 (1.25-1.78); 1.55 (1.29-1.87), respectively) and for NICUs with higher resource utilization at admission (AOR: 1.30 (1.08-1.56), Q4 vs Q1) but not different according to NICU occupancy. CONCLUSION Larger NICUs and more intense resource utilization at admission are associated with higher odds of a composite adverse outcome in very preterm infants.

Abstract
This study describes the association between antibiotic resistance of bacteria causing neonatal bloodstream infection (BSI) and neonatal age to inform empirical antibiotic treatment guidelines. Antibiotic resistance data were analysed for 14 078 laboratory reports of bacteraemia in neonates aged 0-28 days, received by the Health Protection Agency's (now Public Health England) voluntary surveillance scheme for England and Wales between January 2005 and December 2010. Linear and restricted cubic splines were used in logistic regression models to estimate the nonlinear relationship between age and resistance; the significance of confounding variables was assessed using likelihood ratio tests. An increase in resistance in bacteria causing BSI in neonates aged <4 days was observed, which was greatest between days 2-3 and identified an age (4-8 days, depending on the antibiotic) at which antibiotic resistance plateaus to almost unchanging levels. Our results indicate important age-associated changes in antibiotic resistance and support current empirical treatment guidelines.

Abstract
Background Very low birthweight (VLBW) newborns on neonatal intensive care units (NICU) are at increased risk for developing central venous catheter-associated bloodstream infections (CVC BSI). In addition to the established intrinsic risk factors of VLBW newborns, it is still not clear which process and structure parameters within NICUs influence the prevalence of CVC BSI. Methods The study population consisted of VLBW newborns from NICUs that participated in the German nosocomial infection surveillance system for preterm infants (NEO-KISS) from January 2008 to June 2009. Structure and process parameters of NICUs were obtained by a questionnaire-based enquiry. Patient based date and the occurrence of BSI derived from the NEO-KISS database. The association between the requested parameters and the occurrance of CVC BSI and laboratory-confirmed BSI was analyzed by generalized estimating equations. Results We analyzed data on 5,586 VLBW infants from 108 NICUs and found 954 BSI cases in 847 infants. Of all BSI cases, 414 (43%) were CVC-associated. The pooled incidence density of CVC BSI was 8.3 per 1,000 CVC days. The pooled CVC utilization ratio was 24.3 CVC-days per 100 patient days. A low realized staffing rate lead to an increased risk of CVC BSI (OR 1.47; p=0.008) and also of laboratory-confirmed CVC BSI (OR 1.78; p=0.028). Conclusions Our findings show that low levels of realized staffing are associated with increased rates of CVC BSI on NICUs. Further studies are necessary to determine a threshold that should not be undercut.

Abstract
AIMS The aims of this study were to compare rates of late-onset sepsis (LOS) in very preterm or very low birthweight infants before and after relocation to a new nursery and to determine risk factors for LOS. METHODS The study was undertaken at The Royal Women's Hospital, Melbourne, which relocated to a new site in June 2008. Infants with birthweight <1500 g or <32 weeks' gestation, born between July and December 2007 (n= 149) and July and December 2008 (n= 152) were included. Each septic episode was identified from blood cultures taken from patients >48 h after birth and was categorised as definite, probable, uncertain or no sepsis. RESULTS Overall, 117 infants had 218 septic episodes. The proportion of infants with clinical LOS decreased from 29.5% in 2007 to 22.4% in 2008 after the relocation, although this was not statistically significant. There was a significant (P < 0.05) reduction in the severity (definite LOS = most severe) of sepsis in 2008 compared with 2007, and in rates of coagulase-negative staphylococcal LOS. Significant risk factors for LOS were: lower birthweight (g; mean -351, 95% confidence interval (CI) -446, -256); lower gestational age (weeks; mean -2.3, 95% CI -2.8, -1.7) and presence of a percutaneous inserted central catheter (odds ratio (OR) 2.56, 95% CI 1.03, 6.67). CONCLUSIONS There was a significant reduction in the severity of LOS in very preterm and/or very low birthweight infants that correlated with the relocation from the old to new nursery. Smaller and more immature infants with percutaneous central catheters were more at risk.

Abstract
BACKGROUND Because greater percentages of women deliver at hospitals without high-level NICUs, there is little information on the effect of delivery hospital on the outcomes of premature infants in the past 2 decades, or how these effects differ across states with different perinatal regionalization systems. METHODS A retrospective population-based cohort study was constructed of all hospital-based deliveries in Pennsylvania and California between 1995 and 2005 and Missouri between 1995 and 2003 with a gestational age between 23 and 37 weeks (N = 1328132). The effect of delivery at a high-level NICU on in-hospital death and 5 complications of premature birth was calculated by using an instrumental variables approach to control for measured and unmeasured differences between hospitals. RESULTS Infants who were delivered at a high-level NICU had significantly fewer in-hospital deaths in Pennsylvania (7.8 fewer deaths/1000 deliveries, 95% confidence interval [CI] 4.1-11.5), California (2.7 fewer deaths/1000 deliveries, 95% CI 0.9-4.5), and Missouri (12.6 fewer deaths/1000 deliveries, 95% CI 2.6-22.6). Deliveries at high-level NICUs had similar rates of most complications, with the exception of lower bronchopulmonary dysplasia rates at Missouri high-level NICUs (9.5 fewer cases/1000 deliveries, 95% CI 0.7-18.4) and higher infection rates at high-level NICUs in Pennsylvania and California. The association between delivery hospital, in-hospital mortality, and complications differed across the 3 states. CONCLUSIONS There is benefit to neonatal outcomes when high-risk infants are delivered at high-level NICUs that is larger than previously reported, although the effects differ between states, which may be attributable to different methods of regionalization.

Abstract
OBJECTIVE In neonatal intensive care units (NICUs), monitoring hospital-acquired bloodstream infection (BSI) is critical to alert clinicians to variations in the incidence of infection between units and over time. We demonstrate a toolkit of monitoring techniques that account for case mix and could be implemented using routinely available clinical data. This toolkit could enable quality of care comparisons between hospitals to facilitate the sharing of improved practices. DESIGN Prospective study over 4 years. SETTING AND PATIENTS Babies admitted to 2 tertiary London NICUs. METHODS We derived expected numbers of BSI episodes using a Poisson regression risk model adjusting for variations in birth weight, transfers to the NICU from other hospitals, postnatal age, and days spent at each National Health Service level of care. We compared observed and expected numbers of BSI episodes using 2 monitoring techniques: standardized infection ratios (SIRs) and the sequential probability ratio test (SPRT). RESULTS Using the SIR method, observed BSI incidence increased over expected incidence in 2002 at both NICUs, but this increase did not reach statistical significance at the 1% level. Using the SPRT method, neither unit showed a clinically important increase or decrease, defined as a 30% deviation from expected incidence. CONCLUSIONS Risk-adjusted BSI monitoring can be performed using routine hospital data. NICUs could use SIRs for an annual look back at infection incidence and SPRTs for prospective, quarterly monitoring. The SIR and the SPRT methods have different strengths, and both could help clinicians improve infection control and patient care in NICUs.

Abstract
BACKGROUND Although reports of reduced nosocomial infections (NI) in very low birth weight infants have been published, the durability of these gains and changes in secondary outcomes, and clinical practices have less often been published. METHODS This was a retrospective, observational study of NI reduction in very low birth weight infants at two hospital campuses. The intervention began in 2005 with our renewed quality improvement efforts to reduce NI. We compared outcomes before (2000-2005) and after (2006-2009) the intervention by using univariate and multiple regression analyses. RESULTS We reduced NI by 50% comparing 2000-2005 to 2006-2009 (23.6% vs 11.6%, P < .001). Adjusting for covariates, the odds ratio for NI was 0.33 (confidence interval, 0.26 - 0.42, P < .001) in the more recent era. NI were lower even in infants with birth weight 501-1000 grams (odds ratio = 0.38, confidence interval, 0.29 - 0.51, P < .001). We also reduced bronchopulmonary dysplasia (30.2% vs 25.5%, P = .001), median days to regain birth weight (9 vs 8, P = .04), percutaneously placed central venous catheter use (54.8% vs 43.9%, P = .002), median antibiotic days (8 vs 6, P = .003), median total central line days (16 vs 15, P = .01), and median ventilator days (7 vs 5, P = .01). We sustained improvements for three years. CONCLUSIONS Quality improvement efforts were associated with sustained reductions in NI, bronchopulmonary dysplasia, antibiotic use, central line use, and ventilator days.

Abstract
Late-onset sepsis in premature infants is a major cause of morbidity, mortality, and increased medical costs. Risk factors include low birth weight, low gestational age, previous antimicrobial exposure, poor hand hygiene, and central venous catheters. Methods studied to prevent late-onset sepsis include early feedings, immune globulin administration, prophylactic antimicrobial administration, and improved hand hygiene. In this review, we will outline the risk factors for development of late-onset sepsis and evidence supporting methods for prevention of late-onset sepsis in premature infants.

Abstract
Comparisons of bacteraemia incidence between neonatal intensive care units (NICUs) can identify centres with effective infection control, whose practices can be shared with other units. For fair comparisons, infection incidence must be risk-adjusted to control for differences between centres in the vulnerability of babies and the intensity of invasive procedures which can introduce infection. We reviewed risk adjustment methods for between-NICU comparisons of bacteraemia incidence, both in the published literature and in regional and national NICU infection monitoring systems. PubMed and Embase were searched for studies reporting risk-adjusted bacteraemia incidence in more than one NICU. An internet search found NICU infection monitoring systems in Western industrialised countries. In all nine studies that met the inclusion criteria, risk adjustment reduced but did not eliminate variation in bacteraemia incidence between NICUs. In both the studies and the regional monitoring systems, adjustment for baby susceptibility generally involved stratification by factors measured at birth. Adjustment for Length of stay and invasive procedures involved reporting incidence by days with a device, such as central venous catheter days. Methods for NICU infection monitoring lack consistency. Adjustment for factors measured at birth fails to capture changes in susceptibility throughout admission and adjustment for device days does not adequately reflect risk to babies not treated with the device. Further research should address variation in risk for all babies throughout their NICU stay.

Abstract
In the past 10 years, many researchers have examined relationships between hospital staffing and patients' risk of health care-associated infection (HAI). To gain understanding of this evidence base, a systematic review was conducted, and 42 articles were audited. The most common infection studied was bloodstream infection (n=18; 43%). The majority of researchers examined nurse staffing (n=38; 90%); of these, only 7 (18%) did not find a statistically significant association between nurse staffing variable(s) and HAI rates. Use of nonpermanent staff was associated with increased rates of HAI in 4 studies (P<.05). Three studies addressed infection control professional staffing with mixed results. Physician staffing was not found to be associated with patients' HAI risk (n=2). The methods employed and operational definitions used for both staffing and HAI varied; despite this variability, trends were apparent. Research characterizing effective staffing for infection control departments is needed.

Abstract
Neonates are one of the highest risk groups of hospitalized patients for sepsis. There is a wide variation in the incidence and microbial causes of late-onset neonatal sepsis, owing to differences in both patient populations and standards of care in the individual neonatal units. Stratification according to risk factors is required to allow the meaningful comparison of infection rates between units. Knowledge of risk factors is also important in order to target interventions on high-risk aspects of neonatal care. Few independent risk factors for late-onset sepsis have been identified, the most common being birth gestational age and parenteral nutrition. Further work is required to validate that these observations can be generalized, and that they could, therefore, be used to stratify infection rates in multicenter surveillance schemes.

Abstract
Monitoring infection rates is increasingly regarded as an important contributor to safe and high quality health care, especially in intensive care settings. Early-onset neonatal sepsis rates are an important indicator of ante- and intra-partum care, especially as medicalisation of obstetric practice increases. However, surveillance of late-onset neonatal sepsis is required to monitor the quality of Neonatal Intensive Care Unit (NICU)-related care. Infection surveillance on NICUs presents a number of unique challenges, including defining infections, the preponderance of coagulase-negative staphylococci as both pathogens and commensals, and allowing for the influence of important risk factors. Ideally an infection surveillance programme should permit benchmarking of infection rates, and multi-centre programmes have been reported to decrease the incidence of healthcare-associated infections on NICUs. However, further research is required to identify the most clinically- and cost-effective means of surveying NICU-acquired infections before a national programme can be implemented. Until then, considerable value can be obtained from local infection surveillance.
