概括
免费运输到COVID-19疫苗预约并没有增加接种率. 基于行为信息的文本提醒有效,提高了21%的COVID-19增强疫苗接种率和8%的流感疫苗接种率.
科学领域:
- 公共卫生
- 行为经济学
- 卫生政策
背景情况:
- 常规的COVID-19疫苗接种对公共健康至关重要,但接种率,特别是增强剂量,仍然不理想.
- 运输障碍被认为是影响疫苗获取和接种的重要因素.
- 提供免费运输到疫苗接种场所作为干预措施的有效性在很大程度上未得到量化.
研究的目的:
- 评估提供免费往返Lyft乘车对COVID-19疫苗接种率的影响.
- 为了比较免费运输的有效性与行为相关的短信提醒.
- 确定提高疫苗接种率的最具成本效益的策略.
主要方法:
- 这是一项大规模的随机对照试验 (大型研究),涉及美国数百万名CVS药房患者.
- 干预组包括免费的往返Lyft运输到接种疫苗的约会以及七种行为信息的短信提醒.
- 测量结果包括30天的COVID-19增强剂和流感疫苗接种量.
主要成果:
- 与标准护理相比,向疫苗接种地点提供免费的Lyft乘车在增加COVID-19疫苗接种方面没有显著的好处.
- 以行为为基础的短信提醒显著增加了30天的COVID-19提升剂的21% (1.05个百分点).
- 短信提醒也表现出积极的溢出效应,使30天流感疫苗接种增加了8% (0.34个百分点).
结论:
- 免费运输不是增加美国COVID-19疫苗接种率的成本有效策略.
- 以行为为基础的短信提醒是促进COVID-19和流感疫苗接种的高效和可扩展的干预措施.
- 未来的公共卫生政策应该优先考虑基于证据的行为干预措施, 而不是直观而有吸引力的但未经证实的方法.

Preventive Healthcare Services
1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Healthcare Associated Infections II: Preventive Measures
2.6K
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...

Immunological Memory
585
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Cancer Vaccines
351
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

The Availability Heuristic
5.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
