[PMID: 37953182 DOI: 10.1016/j.jcf.2023.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 09/20/2023] [Accepted: 10/26/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND Care guidelines for cystic fibrosis (CF) have been developed to enhance consistent care and to improve health outcomes. We determined if adherence to CF care guidelines predicted P. aeruginosa incidence rates (Pa-IR) at U.S. CF centers in 2018. METHODS This cross-sectional CF Foundation Patient Registry study included 82 adult and 132 pediatric centers. Adherence to 12 guidelines was defined categorically (guideline met) or as a continuous measure (proportion of patients being treated/evaluated per guideline). Association of adherence to individual guidelines with Pa-IR, accounted for center and patient characteristics relevant to Pa-IR and were modeled using random forests and weighted-least-squares (WLS) analyses. RESULTS The mean Pa-IR was 0.2 cases/patient-years at risk (SE 0.0074) for all centers combined. Guideline adherence was lowest for ≥4 bacterial cultures/year (54% of centers) and annual oral glucose tolerance test (OGTT) (48% of centers), and highest for annual non-tuberculous mycobacteria (NTM) sputum culture (98%). The mean number of guidelines met was 6.7 and higher for pediatric (7.3) than adult (5.6) centers, (p<0.001). The number of guidelines met correlated negatively with Pa-IR (β=-0.007, p = 0.043). Macrolide prescription and annual OGTT per guideline were associated with lower and higher Pa-IR, respectively. Centers with lower center-wide lung function, higher proportion of pwCF with low body-mass index, and location in the Southwest had higher Pa-IR. CONCLUSION Overall adherence to guidelines was high except for performing ≥4 bacterial cultures/year and OGTT. Higher Pa-IR was associated with center characteristics and lower guideline adherence. The lower Pa-IR with greater adherence to guidelines suggests that focusing on quality care can positively impact Pa-IR.

Abstract
The respiratory tract of lung transplant recipients (LTR) is likely to be colonized with non-fermentative Gram-negative rods. As a consequence of the improvements in molecular sequencing and taxonomy, an increasing number of bacterial species have been described. We performed a review of the literature of bacterial infections in LTR involving non-fermentative Gram-negative rods with exclusion of Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Achromobacter spp. and Burkholderia spp. Overall, non-fermenting GNR were recovered from 17 LTR involving the following genera: Acetobacter, Bordetella, Chryseobacterium, Elizabethkinga, Inquilinus, and Pandoraea. We then discuss the issues raised by these bacteria, including detection and identification, antimicrobial resistance, pathogenesis, and cross-transmission.

Abstract
PURPOSE OF REVIEW This article reviews the impact of some of the most recent changes in clinical care management in cystic fibrosis on infection prevention practice and advice for people with cystic fibrosis. RECENT FINDINGS People with cystic fibrosis (CF) consistently highlight infection control as one of their major concerns. Infection prevention guidance and practice has facilitated successful decreases in rates of many transmissible CF pathogens. The coronavirus disease 2019 pandemic highlighted the clinical significance of respiratory viral infections and has accelerated the implementation of remote monitoring and telemedicine consultations as standard practice in CF. The continued improvement in health of the CF population is being further augmented by the introduction of new therapies, in particular cystic fibrosis transmembrane conductance regulator modulators. Infection prevention will remain pertinent to CF care, but these recent changes in clinical practice will have ongoing implications for infection prevention guidance in CF. SUMMARY Recent changes in CF clinical care have implications that will lead to further evolution of infection control practice and advice.

Abstract
BACKGROUND Barriers to implementing infection prevention and control (IP&C) practices may be experienced by healthcare workers (HCWs) caring for people with CF (PwCF), PwCF, and their families. We hypothesized that these stakeholders from CF centers with early adoption of the updated 2013 IP&C guideline would experience fewer barriers implementing selected recommendations compared to stakeholders from CF centers with delayed adoption. METHODS In 2018-2019 we surveyed HCWs and PwCF/parents from 25 CF centers to identify knowledge, attitude, and practice barriers. Each center recruited five HCWs with different occupations. Pediatric centers recruited five parents of children <18 years old and five young adults 18-21 years old. Adult centers recruited 10 adults ≥18 years old. We determined respondents' knowledge scores, the proportion who agreed with or perceived health benefits from recommendations, and reported adherence to recommendations. RESULTS Knowledge scores, perception of health benefits, and adherence to selected practices were similar among participants from centers with early vs. delayed adoption, yet generally lower for inpatient nurses. IP&C practitioners were less likely to perceive health benefits from PwCF wearing masks and HCWs wearing gowns and gloves. Among HCWs, 57% educated >75% of PwCF/parents about IP&C and 43% advised >75% of PwCF/parents to avoid socializing with other PwCF. Among PwCF/parents, 69%, 53%, and 56% reported discussions with their care teams about performing hand hygiene, avoiding socialization, or the 2013 IP&C guideline, respectively. CONCLUSIONS Our findings suggest opportunities for targeted education for specific HCW occupations and for PwCF and their families.

Abstract
BACKGROUND Multiple factors affect incident infection rates (IIR) for Pseudomonas aeruginosa (PA) and methicillin resistant Staphylococcus aureus (MRSA) at CF care centers. We assessed changes in IIR across CF centers temporally associated with the 2013 Infection/Prevention & Control guidelines controlling for center-specific factors. METHODS Using the CF Foundation Patient Registry we defined and measured changes in IIR between 2010-2012 and 2014-2016. Data were compared to non-CF rates of MRSA and resistant PA in geographically similar regions. Characteristics of each CF center (n centers: Adult 54 in 2010 to 82 in 2016. Pediatric ∼106) and their respective population were evaluated for associations with IIR and with changes in IIR between the study periods. RESULTS Across the years 35613 patients were included. Incident-infection rates for PA (mean 19.2±0.04% Pediatric, 21.2±0.07% Adult centers) were higher than for MRSA (mean 9.4±0.03% Pediatric, 7.8±0.03% Adult). The IIR decreased for MRSA (-1.54±0.54%, p<0.001) and PA (-4.77±0.63%, p<0.001) at Pediatric but only for PA (-3.20±1.31, p=0.02) at Adult centers. Except for Adult CF, MRSA rates (CF and non-CF) were highest in the South. In 2014-2016, private insurance and a higher proportion of LatinX patients at a center were associated with lower MRSA IIR while larger center size, higher proportion of LatinX, and lower mean center-wide lung function were associated with higher PA IIR. Higher IIR in 2010-2012, were predictive of a more pronounced decrease in IIR in 2014-2016 for MRSA and PA (p<0.001). Different factors indicative of lower social status (smoking, insurance, education) in 2010-2012 predicted decreases in MRSA or PA IIR. CONCLUSION Comparisons of IIR across U.S. CF centers should consider location, ethnic background and socio-economic variables of a center's population.

Stockwell RE, Wood MEL, Ballard E, Moore V, Wainwright CE, Bell SC. Current infection control practices used in Australian and New Zealand cystic fibrosis centers. BMC Pulm Med 2020; 20:16. [PMID: 31952502 PMCID: PMC6969421 DOI: 10.1186/s12890-020-1052-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Accepted: 01/10/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The 2013 update of the Infection Prevention and Control (IP&C) Guideline outlined recommendations to prevent the spread of CF respiratory pathogens. We aimed to investigate the current infection control practices used in Australian and New Zealand (NZ) CF centers. METHODS Two online surveys were distributed to Australian and NZ CF centers regarding the uptake of selected IP&C recommendations. One survey was distributed to all the Medical Directors and Lead CF Nurses and the second survey was distributed to all the Lead CF Physiotherapists. RESULTS The response rate was 60% (60/100) for medical/nursing and 58% (14/24) for physiotherapy. Over 90% (55/60) of CF centers followed CF-specific infection control guidelines and consistent infection control practices were seen in most CF centers; 76% (41/54) had implemented segregation strategies for ambulatory care and no CF centers housed people with CF in shared inpatient accommodation. However, the application of contact precautions (wearing gloves and apron/gown) by healthcare professionals when reviewing a CF person was variable between CF center respondents but was most often used when seeing CF persons with MRSA infection in both ambulatory care and hospital admission (20/50, 40% and 42/45, 93% of CF centers, respectively). Mask wearing by people with CF was implemented into 61% (36/59) of centers. Hospital rooms were cleaned daily in 79% (37/47) of CF centers and the ambulatory care consult rooms were always cleaned between consults (49/49, 100%) and at the end of the clinic session (51/51, 100%); however the staff member tasked with cleaning changed with 37% (18/49) of CF centers responding that CF multidisciplinary team (MDT) members cleaned between patients whereas at the end of the clinic session, only 12% (6/51) of the CF MDT cleaned the consult room. CONCLUSIONS Overall, Australian and NZ CF centers have adopted many recommendations from the IP&C. Although, the application of contact precautions was inconsistent and had overall a low level of adoption in CF centers. In ~ 25% of centers, mixed waiting areas occurred in the ambulatory care. Given the variability of responses, additional work is required to achieve greater consistency between centers.
