Published: August 2022

Background

Identifying caregiver availability, particularly for patients with dementia or those with a disability, is critical to informing the appropriate care planning by the health systems, hospitals, and providers. This information is not readily available, and there is a paucity of pragmatic approaches to automatically identifying caregiver availability and type.

Objective

Our main objective was to use medical notes to assess caregiver availability and type for hospitalized patients with dementia. Our second objective was to identify whether the patient lived at home or resided at an institution.

Methods

In this retrospective cohort study, we used 2016-2019 telephone-encounter medical notes from a single institution to develop a rule-based natural language processing (NLP) algorithm to identify the patient’s caregiver availability and place of residence. Using note-level data, we compared the results of the NLP algorithm with human-conducted chart abstraction for both training (749/976, 77%) and test sets (227/976, 23%) for a total of 223 adults aged 65 years and older diagnosed with dementia. Our outcomes included determining whether the patients (1) reside at home or in an institution, (2) have a formal caregiver, and (3) have an informal caregiver.

Results

Test set results indicated that our NLP algorithm had high level of accuracy and reliability for identifying whether patients had an informal caregiver (F1=0.94, accuracy=0.95, sensitivity=0.97, and specificity=0.93), but was relatively less able to identify whether the patient lived at an institution (F1=0.64, accuracy=0.90, sensitivity=0.51, and specificity=0.98). The most common explanations for NLP misclassifications across all categories were (1) incomplete or misspelled facility names; (2) past, uncertain, or undecided status; (3) uncommon abbreviations; and (4) irregular use of templates.

Conclusions

This innovative work was the first to use medical notes to pragmatically determine caregiver availability. Our NLP algorithm identified whether hospitalized patients with dementia have a formal or informal caregiver and, to a lesser extent, whether they lived at home or in an institutional setting. There is merit in using NLP to identify caregivers. This study serves as a proof of concept. Future work can use other approaches and further identify caregivers and the extent of their availability.

BACKGROUND

Digital Health Technologies (DHTs), such as electronic health records and prescribing systems, are transforming healthcare delivery around the world. The quality of information in DHTs is key to the quality and safety of care. We developed a novel Clinical Information Quality (CLIQ) Framework to assess the quality of clinical information in DHTs.

OBJECTIVE

This study explored clinicians’ perspectives on the relevance, definition, and assessment of information quality dimensions in the CLIQ Framework

METHODS

A systematic and iterative eDelphi approach was used to engage clinicians with information governance roles or interest, recruited through purposive and snowball sampling techniques. Data were collected using semi-structured online questionnaires until consensus was reached on the information quality dimensions in the CLIQ Framework. Responses on the relevance of the dimensions were summarized to inform decisions on retention of dimensions according to pre-specified rules. Thematic analysis of the free-text responses was used to revise definitions and assessment of dimensions.

RESULTS

Thirty-five clinicians from ten countries participated in the study which was concluded after the second round. Consensus was reached on all the dimensions in the CLIQ Framework i.e., accuracy, completeness, interpretability, plausibility, provenance, relevance, accessibility, portability, security, timeliness, conformance, consistency, and maintainability. A new dimension, searchability, was introduced to account for the ease of finding needed information in the DHTs. Certain dimensions were renamed, and some definitions were rephrased to improve clarity.

CONCLUSIONS

The CLIQ Framework reached a high expert consensus and clarity of language relating to the information quality dimensions. The framework can be used by healthcare professionals and institutions as a pragmatic tool for identifying and forestalling information quality problems which could compromise patient safety and quality of care.

Land cover information based on remote sensing imagery is effective information for land use management. The use of Sentinel-2 imagery is considered to be able to provide better information on land cover because it has a spatial accuracy of 10 meters. Convolutional Neural Networks is one of the deep learning methods that can be used for image interpretation in order to obtain image classification results which will later obtain information about land cover. PCA-CNN (Principal Component Analysis-Convolutional Neural Network) is a development method of the Convolutional Neural Network method which gives special treatment to the dimension reduction process in the input data. The dimension reduction process is carried out by utilizing the PCA method so that the data processing process becomes faster without losing important information so that better method performance is obtained. The PCA-CNN method is implemented on a dataset of the Situbondo district which is classified into five land cover classes. The results of the PCA-CNN method have an Overall Accuracy of 94.4% and Kappa Indeks 0,92 with 100 epochs of repeated experiments.

Published: August 2022

To determine how Zn and ractopamine hydrochloride (RAC) supplementation affect the longissimus thoracis muscle proteome in beef cattle, 48 high percentage Angus steers (494±18.2 kg) were utilized in a 2×2 factorial study design. Steers were blocked by body weight (BW) and genetic gain potential (GeneMax; Zoetis, Parsippany, NJ) into control (CON; analyzed 36 mg Zn/kg dry matter [DM]) or supranutritional Zn (SUPZN; CON+60 mg Zn/kg DM from ZnSO4+60 mg Zn/kg DM from Zn-amino acid complex; Availa Zn, Zinpro, Eden Prairie, MN) dietary treatments (ZNTRT). Starting 28 d prior to harvest, steers were blocked by BW within ZNTRT to RAC treatments (RACTRT) of 0 (NO) or 300 mg·steer−1·d−1 (RAC; Actogain 45, Zoetis). After 15 d on RACTRT, longissimus thoracis biopsies were collected from all steers for proteomic analysis. Twenty-eight steers (n=7 per treatment) were harvested at a commercial abattoir on Day 90. A ZNTRT×RACTRT effect showed SUPZN-RAC steers had a greater dressing percentage than other treatments (P≤0.02). Steers fed SUPZN had a greater hot carcass weight, carcass-adjusted final BW, overall average daily gain, and overall gain to feed (P≤0.05). Differentially abundant proteins involved in energy metabolism, muscle structure, and protein synthesis potentially indicate muscle fiber characteristic differences because of Zn and RAC supplementation.Both myosin light chain kinase 2 and eukaryotic translation initiation factor 5A-1 were more abundant in SUPZN-RAC steers than SUPZN-NO (P≤0.05) or CON-NO (P≤0.04) steers when analyzed for phosphorylation modifications. L-lactate dehydrogenase B was more abundant in SUPZN-NO steers than CON-NO (P=0.03) or CON-RAC (P=0.01) steers. In conclusion, increased Zn supplementation may be needed to optimize the hypertrophic effects of RAC through its effects on the longissimus thoracis proteome.

Noise is a longitudinal wave which is known as pressure wave. Therefore, noise is expected to disturb the stability of fluid flow. The disturbance is expected to increase the heat transfer of fluid flow. In this research, noise was applied to condenser cooling of air in a refrigeration system. Effect generated is directly measured by amount of heat capable to be released into the air passing condenser, and indirectly by the compressor energy required and coefficient of performance (COP) of refrigeration system. Experimental results indicate that noise with intensity level of 115 dB with frequency around 100–500 Hz at air velocity of 5,3 m / s increases the amount of heat capable to be released into the air which is 10,1%, reduces compressor energy to 12,8% and increases coefficient of performance (COP) by 11,4% compared to flow without noise.

Elvira Santa Cruz Ossa, Roxane: editorialismo infantil, agencia intelectual y social en el Chile moderno

Su agencia se hace observable en dos líneas: su autoconstrucción como una ‘presencia de papel’ respaldada en su trabajo editorial, y la superación de los límites del papel hacia el campo social en donde ejerció desde sus distintas formas de subjetividad: la editora, la intelectual, la maestra y la madre, todas ellas permitieron a Roxane trazar el ‘corral’ (Montes) para la infancia chilena que fuera a su vez de protección y de apertura cultural.
