A Perspective on a Quality Management System for AI/ML-Based Clinical Decision Support in Hospital Care.

Although many artificial intelligence (AI) and machine learning (ML) based algorithms are being developed by researchers, only a small fraction has been implemented in clinical-decision support (CDS) systems for clinical care. Healthcare organizations experience significant barriers implementing AI/ML models for diagnostic, prognostic, and monitoring purposes. In this perspective, we delve into the numerous and diverse quality control measures and responsibilities that emerge when moving from AI/ML-model development in a research environment to deployment in clinical care.

Practice-Level Association between Antibiotic Prescribing and Resistance: An Observational Study in Primary Care.

A direct relation between antibiotic use and resistance has been shown at country level. We aim to investigate the association between antibiotic prescribing for patients from individual Dutch primary care practices and antibiotic resistance of bacterial isolates from routinely submitted urine samples from their patient populations. Practices' antibiotic prescribing data were obtained from the Julius Network and related to numbers of registered patients.

Oseltamivir-resistant pandemic A(H1N1) 2009 influenza viruses detected through enhanced surveillance in the Netherlands, 2009-2010.

Enhanced surveillance of infections due to the pandemic A(H1N1) influenza virus, which included monitoring for antiviral resistance, was carried out in the Netherlands from late April 2009 through late May 2010. More than 1100 instances of infection with the pandemic A(H1N1) influenza virus from 2009 and 2010 [A(H1N1) 2009] distributed across this period were analyzed. Of these, 19 cases of oseltamivir-resistant virus harboring the H275Y mutation in the neuraminidase (NA) were detected.

Modelling of early viral kinetics and pegylated interferon-alpha2b pharmacokinetics in patients with HBeag-positive chronic hepatitis B.

Background: Pegylated interferon alpha2b (PEG-IFN-alpha(2b) is effective for the treatment of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B, although its mechanism of action remains unclear. HBeAg loss is achieved in 36% of patients after one year of PEG-IFN-alpha2b treatment and combination therapy with lamivudine is not superior to PEG-IFN-alpha2b monotherapy.

Methods: Early pharmacokinetics and viral kinetics were analysed in patients treated for 52 weeks with PEG-IFN-alpha2b with or without lamivudine.

Pseudo-outbreak of hepatitis B virus infection associated with contamination of a semiautomatic cap remover.

A pseudo-outbreak of hepatitis B virus caused by cross-contamination from a semiautomatic cap remover for blood collection tubes is reported. The source of the outbreak was elucidated by using basic epidemiological methods. Laboratories should always be critical about their results in order to identify contamination problems.

Outbreak of infection with a multiresistant Klebsiella pneumoniae strain associated with contaminated roll boards in operating rooms.

An outbreak with a multiresistant Klebsiella pneumoniae (MRKP) strain among seven patients admitted to the adult intensive care unit (ICU) of a regional teaching hospital in The Netherlands was investigated. Epidemiologic investigations revealed a short delay between an operation and the acquisition of the MRKP strain. A case-control study comprising 7 cases and 14 controls was conducted to identify the risk factors associated with the acquisition of the MRKP strain.

High percentage of methicillin-resistant Staphylococcus aureus isolates with reduced susceptibility to glycopeptides in The Netherlands.

While testing the in vitro activities of 14 antimicrobial agents against 107 methicillin-susceptible Staphylococcus aureus (MSSA) and 250 methicillin-resistant S. aureus (MRSA) isolates collected in The Netherlands, we found to our surprise that 19 (7.6%) MRSA isolates were suspected of having reduced susceptibilities to the glycopeptides when the Etest system (AB Biodisk, Solna, Sweden) was used with a large inoculum (no.

Use of multienzyme multiplex PCR amplified fragment length polymorphism typing in analysis of outbreaks of multiresistant Klebsiella pneumoniae in an intensive care unit.

We developed and optimized a new modified amplified fragment length polymorphism (AFLP) typing method to obtain a multibanding fingerprint that can be separated by agarose gel electrophoresis. Both to maximize the discriminatory power and to facilitate the computer-assisted analysis, bacterial DNA was digested with four different restriction enzymes. After ligation of adaptors to the DNA fragments, PCR testing of various single primers was performed.
