Abstract Aim Patient‐reported outcome measures (PROMs) are increasingly used in palliative care to evaluate patients' symptoms and conditions. Healthcare providers often collect PROMs through conversations. However, the manual entry of these data into electronic medical records can be burdensome for healthcare providers. Voice recognition technology has been explored as a potential solution alleviating this burden. research on voice is lacking. This study aimed verify use machine learning...

Pain is subjective, and self-reporting pain might be challenging. Studies conducted to detect using biological signals real-time self-reports are limited. We evaluated the feasibility of collecting data on healthy females' menstrual preliminary analysis. Five adult females participated. They wore two wristwatch devices (Silmee Fitbit) a Holter ECG (electrocardiogram) during menstruation record intensity timing. Subsequently, we analyzed correlation between heart pulse rates assessed pre-...

Background/Objectives: The global nursing shortage encompasses issues such as the uneven nurse distribution in low- and middle-income countries, outflow to other retirement developed necessitating effective retention strategies. Our objective was clarify changes facility selection reasons among Japanese nurses after changing jobs personal attributes influencing selection. Methods: In January 2023, an online survey conducted licensed practical nurses, registered midwives, public health Japan....

Elucidating nurses’ work values will contribute to creating a environment consistent with individual and help them overcome challenging situations. This study aimed create short version of the Nurses’ Work Values Scale verify its psychometric properties usability among nurses, public health midwives, licensed practical nurses. The was developed in three steps. In Step 1, 12‐item scale created from original 30‐item via multidimensional item response theory based on data obtained 1587 2, we...

This study aimed to classify nurses with similar work values into subgroups by examining their intrinsic, extrinsic, social, and prestige values. Additionally, we clarified the characteristics of obtained using personal attributes, engagement, life satisfaction. Using a cross-sectional observational design, randomly sampled 52 hospitals in Tohoku region Japan conducted self-administered questionnaire survey 2600 nurses. Latent profile analysis was performed identify number subgroups. Of 1627...

Although opioids have been shown to be effective for cancer pain, opioid-induced adverse events (AEs) are common. To date, little is known about the differences in risks of AEs by opioid type. This study was performed compare prevalence across commonly used analgesic treatment Japan.This conducted as a preplanned secondary analysis multicenter prospective longitudinal inpatients with pain who received specialized palliative care relief. We assessed daily until termination follow-up. rated...

Pain assessment becomes challenging for patients unable to self-report, given the subjective nature of pain. This study introduces an automatic pain detection model utilizing biological signals from wristwatch wearables and time series data with cancer experiencing Biological were obtained 10 7 days during their hospitalization. A total 73,154 minutes 407 reports obtained. We developed classifiers detect moderate or severe above personalized goal by several machine learning algorithms using...

【目的】患者報告型アウトカムを用いて緩和ケアの質をアウトカムの視点から評価するための患者登録システムの実施可能性を検証すること.【方法】電子的データ収集による患者登録システムを2021年に8施設で運用した.1カ月間に緩和ケアチームが新規介入依頼を受けた全入院患者を前向きに登録した.症状評価はIPOSまたはESASを介入時,3日後,介入から1週間ごとに取得した.主要評価項目は患者と医療者による症状評価尺度への回答率である.【結果】318人が登録.患者の回答率は介入時59.1%,介入後37.0%で医療者の回答率は介入時98.4%,介入後70.3%だった.緩和ケアチームからは「患者の回答はサポートが必要で,タブレットよりも紙がよい」,「調査日や全体の管理が負担」などの意見が出た.【考察】実施可能性があると考えられる一方で,システムや運用方法の改善点が明らかになり,実装に向けた貴重な情報が得られた.

State transition of sodium ion selective channel on the excitable membrane was modeled by setting more than 14 subclasses closed states and three inactivated states. The temporal changes in amount species were described 20 differential equations. By applying H infinite control principle, we have computed closed, open time courses these sensitive to electrical voltage gap across membrane. present work will be available for evaluating noise filtering function channel.

Abstract Purpose: Although opioids have been shown to be effective for cancer pain, opioid-induced adverse events (AEs) are common. To date, there is very little evidence suggesting that any one opioid agonist has a substantially better AE profile than other. This study was performed compare the prevalence of AEs across commonly used analgesic treatment in Japan. Methods: conducted as preplanned secondary analysis multicenter prospective longitudinal inpatients with pain who received...
