Accuracy and costs of bedside methods for confirming nasoenteral feeding tube position: a diagnostic accuracy study.

Aim: To analyze the accuracy and costs of bedside methods for confirming the position of a nasoenteral feeding tube newly inserted blindly by nurses.

Design: Diagnostic accuracy study of three clinical methods (ultrasound, epigastric auscultation, and pH measurement) compared to radiography. The direct costs of each method used to confirm the positioning of the nasoenteral tube were also measured.

Patient safety culture in times of the COVID-19 pandemic: a cross-sectional study in a hospital.

Objectives: to assess patient safety culture during the COVID-19 pandemic and identify the dimensions that need to be improved in hospital settings and which sector, open or closed, direct or indirect care, exhibits a higher level of safety culture.

Methods: a descriptive and cross-sectional study. The validated version for Brazil of the Hospital Survey on Patient Safety Culture instrument was applied to assess patient safety culture.

Agreement Between Epigastric Auscultation and pH Measurement in the Confirmation of Nasoenteral Tube Placement.

Aim: This study aimed to evaluate the agreement between epigastric auscultation and pH measurement in the confirmation of nasoenteral tube placement.

Method: A cross-sectional study carried out in a medium-sized private hospital in the interior of the state of São Paulo. Forty-nine patients who were submitted to ninety insertion procedures and confirmation of tube placement.

Impact of a quality improvement programme on the preparation and administration of medications via a nasoenteral feeding tube: 2014-2019 intervention study.

Aims: Evaluate the impact of a quality improvement programme on the reduction of feeding tube obstruction frequencies, analyse the predictive variables of this safety incident, and estimate the economic costs related to the quality improvement programme during the period from 2014 to 2019.

Methods: Plan-Do-Study-Act cycles were performed to test the changes in drug preparation and administration processes via a nasoenteral feeding tube and to evaluate the outcome, process and balance measures. Statistical control charts were elaborated, and the bottom-up direct costing methodology was used to estimate the costs of the improvement programme.

Adherence to safety barriers in medication administration: patients' perception.

Objective: to analyze the perception of patients about health professionals' adherence to safety barriers in medication administration.

Method: cross-sectional and correlational study carried out in a hospital in the countryside of São Paulo, with a total of 249 adult patients admitted to the medical clinic. An electronic form developed by the researcher was used.

Accuracy of the combined method (auscultation and pH measurement) and ultrasonography for confirmation of gastric tube placement: a study protocol for a prospective study.

Introduction: Patients using a nasogastric tube (NGT) are vulnerable to adverse events, therefore proper assessment of these patients, verification of the correct tube placement and constant monitoring by the nursing staff are strategies that can reduce adverse events and risks associated with the care. The aim of this study will be to assess the accuracy of the combined method (auscultation and pH measurement) and ultrasonography for confirmation of gastric tube placement compared with the X-ray method. A further aim will be to measure and provide evidence for the direct costs of each method of confirming NGT placement and to evaluate the impact of each method on the mean direct cost of the patient.

Quality improvement programme reduces errors in oral medication preparation and administration through feeding tubes.

Background: Patients with nasogastric/nasoenteric tube (NGT/NET) are at increased risk of adverse outcomes due to errors occurring during oral medication preparation and administration.

Aim: To implement a quality improvement programme to reduce the proportion of errors in oral medication preparation and administration through NGT/NET in adult patients.

Methods: An observational study was carried out, comparing outcome measures before and after implementation of the integrated quality programme to improve oral medication preparation and administration through NGT/NET.

Comparative analysis of the shrinkage stress of composite resins.

The aim of this study was to compare the shrinkage stress of composite resins by three methods. In the first method, composites were inserted between two stainless steel plates. One of the plates was connected to a 20 kgf load cell of a universal testing machine (EMIC-DL-500).

Transmission of composite polymerization contraction force through a flowable composite and a resin-modified glass ionomer cement.

The purpose of this study was to evaluate the individual contraction force during polymerization of a composite resin (Z-250), a flowable composite (Filtek Flow, FF) and a resin-modified glass ionomer cement (Vitrebond, VB), and the transmission of Z-250 composite resin polymerization contraction force through different thicknesses of FF and VB. The experiment setup consisted of two identical parallel steel plates connected to a universal testing machine. One was fixed to a transversal base and the other to the equipment's cross head.
