Abstract

Background:

The COVID- 19 pandemic prompted rapid development of scarce resource allocation policies (SRAP) in case demand for critical health services eclipsed capacity. We sought to test whether a brief, educational video could improve alignment of participant values and preferences with the tenets of the University of California Health's SRAP in a post hoc analysis of a randomized controlled trial (RCT) conducted during the pandemic.

Methods:

An RCT of an educational video intervention embedded in a longitudinal web-based survey conducted from May to December 2020, analyzed in August 2024. The "explainer" video intervention was approximately 6 min long and provided an overview of the mechanics and ethical principles underpinning the UC Health SRAP, subtitled in six languages. California residents were randomized to view the intervention or not, stratified by age, sex, education, racial identity, and self-reported health care worker status. Non-California residents were assigned to the control group. 1,971 adult participants were enrolled at baseline, and 939 completed follow-up. 770 participants with matched baseline and follow-up responses were analyzed. Self-reported survey assessments of values regarding components of SRAP were scored as the percentage of agreement with the UC Health SRAP as written. Participants responded to items at baseline and follow-up (approximately 10 weeks after baseline), with randomization occurring between administrations.

Results:

After the intervention, overall agreement improved by a substantial margin of 5.2% (from 3.8% to 6.6%, P <.001) for the intervention group compared to the control group. Significant changes in agreement with SRAP logistics and health factors were also observed in the intervention group relative to the control, while no significant changes were noted for social factors. Differential intervention effects were observed for certain demographic subgroups.

Conclusions:

A brief educational video effectively explains the complex ethical principles and mechanisms of the SRAP, as well as how to improve the alignment of participant values with the foundational principles of UC Health SRAP. This directly informs practice by providing a framework for educating individuals about the use of these policies during future situations that require crisis standards of care, which can, in turn, enhance agreement and buy-in from affected parties.

Strategies for Assessing and Addressing Confounding

Strategies for Assessing and Addressing Confounding

Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Group Design

Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Decision Making: P-value Method

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

The Anchoring-and-Adjustment Heuristic

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...
