- ワクチン接種率の格差をなくすには 標的を絞った介入が必要である.
研究 の 目的:
- インフルエンザワクチン接種における様々な介入の有効性を包括的に評価する.
- 異なる人口集団に対して最も効果的な介入戦略を特定する.
- 世界的なインフルエンザ予防接種を強化するための証拠に基づいた勧告を提供すること.
主な方法:
- 2023年4月まで 体系的な文献検索が行われました
- インフルエンザワクチン接種における介入の有効性を評価する実験的研究が含まれています.
- 95% 信頼区間 (CI) を有するリスク比 (RR) をまとめるために,ランダム効果メタ解析を用いた.
主要な成果:
- 2,390,119人の参加者を含む合計180件の研究が分析されました.
- 予防接種率は,合計RRが1. 26 (95%CI,1. 21から1. 32) であった.
- 提供者による介入は医療従事者に対して効果的であり,受給者による介入は妊婦に対して効果的であり,高齢者や子供に対する多目的戦略は効果的であった.

Pneumonia V: Nursing management and Prevention
2.5K
Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Healthcare Associated Infections II: Preventive Measures
2.8K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Study Designs in Epidemiology
415
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions
2.4K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
