Validation of the Incidence of Reported Periprosthetic Joint Infections in Total Hip and Knee Arthroplasty in the Dutch Arthroplasty Register

The Journal of Arthroplasty (2023)

Mirthe H. W. van Veghel Maartje Belt Anneke Spekenbrink–Spooren Martijn F. L. Kuijpers Tjallie van der Kooi

Arthroplasty registers underreport the incidence of periprosthetic joint infections (PJIs). We validated the incidence of reported PJIs in total hip arthroplasties (THAs) and total knee arthroplasties (TKAs) in the Dutch Arthroplasty Register (LROI) using data from the Dutch National Nosocomial Surveillance Network (PREZIES).

Improved individual hand hygiene compliance with a multimodal hand hygiene intervention – the results of the PROHIBIT (Prevention of Hospital Infections By Intervention and Training) project

Antimicrobial Resistance and Infection Control (2015)

Tjallie van der Kooi Henny P. A. Boshuizen Sabine C. de Greeff Hajo Grundmann Walter Zingg

The PROHIBIT study aimed at inventorying and analysing national and local infection prevention activities in Europe and to test two interventions of proven efficacy in central venous catheter (CVC) bloodstream infection (CRBSI) reduction: a multimodal CVC bundle and a multimodal hand hygiene (HH) improvement strategy.

Antibiotic use and other risk factors at hospital level for outbreaks with Clostridium difficile PCR ribotype 027

Journal of Medical Microbiology (2008)

Tjallie van der Kooi Maike Koningstein A. D. Lindemans Daan W. Notermans Ed J. Kuijper

The first Dutch outbreak due to Clostridium difficile ribotype 027 was observed in mid-2005; by the end of that year, eight hospitals were affected. To study the relationship between hospital-wide antibiotic use and the incidence of 027-linked C. difficile-associated disease (CDAD) three study groups were made: group A, all eight hospitals with an 027-associated epidemic; group B, five of a total of six hospitals with occasional 027 cases, without an increase in CDAD; and group C, ten randomly selected hospitals with no reported 027 epidemics or isolated 027 cases. Quarterly data on CDAD incidences, hygiene measures and the use of fluoroquinolones, second- and third-generation cephalosporins, extended-spectrum penicillins, penicillins with beta-lactamase inhibitors, carbapenems, lincomycins and macrolides were collected for 2004 and 2005, and divided into pre-epidemic and epidemic periods. Using a multilevel Poisson regression analysis, CDAD incidence was linked to antibiotic use in the previous quarter and to certain hygiene measures. In the pre-epidemic period, the total use of the studied antibiotics was comparable between affected and unaffected hospitals. Higher use of second-generation cephalosporins, macrolides and all of the studied antibiotics were independently associated with a small increase in CDAD incidence [relative risk (95% confidence interval): 1.14 per increase of 100 defined daily doses per 10,000 bed days (1.06-1.23), 1.10 (1.01-1.19) and 1.02 (1.01-1.03), respectively]. However the effect was too small to predict which hospitals might be more prone to 027-associated outbreaks.

The Role of Streptococcus Agalactiae in Surgical Site and Non-Invasive Bacterial Infections: A Systematic Review and Meta-Analysis

SSRN Electronic Journal (2018)

Simon M. Collin Nandini Shetty Rebecca Guy Victoria Nyawira Nyaga Ann Bull

Background: Group B streptococcal (GBS; Streptococcus agalactiae) disease epidemiology outside of pregnancy and the neonatal period is poorly characterised. We aimed to quantify the role of GBS as a cause of surgical site and non-invasive infections at all ages.

Hand hygiene improvement of individual healthcare workers: results of the multicentre PROHIBIT study

Antimicrobial Resistance and Infection Control (2022)

Tjallie van der Kooi Hugo Sax Hajo Grundmann Didier Pittet Sabine C. de Greeff

Abstract Background Traditionally, hand hygiene (HH) interventions do not identify the observed healthcare workers (HWCs) and therefore, reflect HH compliance only at population level. Intensive care units (ICUs) in seven European hospitals participating in the “Prevention of Hospital Infections by Intervention and Training” (PROHIBIT) study provided individual HH compliance levels. We analysed these to understand the determinants and dynamics of individual change in relation to the overall intervention effect. Methods We included HCWs who contributed at least two observation sessions before and after intervention. Improving, non-changing, and worsening HCWs were defined with a threshold of 20% compliance change. We used multivariable linear regression and spearman’s rank correlation to estimate determinants for the individual response to the intervention and correlation to overall change. Swarm graphs visualized ICU-specific patterns. Results In total 280 HCWs contributed 17,748 HH opportunities during 2677 observation sessions. Overall, pooled HH compliance increased from 43.1 to 58.7%. The proportion of improving HCWs ranged from 33 to 95% among ICUs. The median HH increase per improving HCW ranged from 16 to 34 percentage points. ICU wide improvement correlated significantly with both the proportion of improving HCWs (ρ = 0.82 [95% CI 0.18–0.97], and their median HH increase (ρ = 0.79 [0.08–0.97]). Multilevel regression demonstrated that individual improvement was significantly associated with nurse profession, lower activity index, higher nurse-to-patient ratio, and lower baseline compliance. Conclusions Both the proportion of improving HCWs and their median individual improvement differed substantially among ICUs but correlated with the ICUs’ overall HH improvement. With comparable overall means the range in individual HH varied considerably between some hospitals, implying different transmission risks. Greater insight into improvement dynamics might help to design more effective HH interventions in the future.

P004: Implementing an extensive central venous catheter bundle in the Ospedale Papa Giovanni XXIII (formerly Ospedali riuniti) of Bergamo, Italy: experiences and impact

Antimicrobial Resistance and Infection Control (2013)

Alfredo Raglio Tjallie van der Kooi Giuseppe Galbiati F Averara A Serna Ortega

As a participant in the PROHIBIT study (Prevention of Hospital Infections by Intervention and Training) our hospital was randomized to evaluate an extensive central venous catheter (CVC) bundle in the intensive care (ICU). Bundle compliance and catheter-related blood stream infections (CRBSI) incidence were monitored.
