Ethical Issues

981
Nurses are essential in patient care, upholding the ethical principles of their profession and effectively navigating ethical dilemmas. Neglecting ethical issues can lead to inadequate patient care, compromised therapeutic relationships, and moral distress among healthcare workers.

Models of Health Promotion and Illness Prevention I01:25

Models of Health Promotion and Illness Prevention I

2.0K
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Wilcoxon Signed-Ranks Test for Matched Pairs01:09

Wilcoxon Signed-Ranks Test for Matched Pairs

140
The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Introduction to Nonparametric Statistics01:28

Introduction to Nonparametric Statistics

725
Nonparametric statistics offer a powerful alternative to traditional parametric methods, useful when assumptions about the population distribution cannot be made. Unlike parametric tests, which require data to follow a specific distribution with well-defined parameters (such as the mean and standard deviation), nonparametric tests do not require such constraints. This makes them particularly valuable when dealing with small sample sizes, skewed data, or ordinal and categorical variables.

Sign Test for Nominal Data01:12

Sign Test for Nominal Data

101
The sign test is a nonparametric method used to evaluate hypotheses about the median of a single sample or to compare the medians of two related samples. The sign test is particularly useful when dealing with nominal data, which includes distinct categories without an inherent order, such as names, labels, and preferences. Nominal data restricts statistical analysis to evaluating population proportions rather than mean or median values that require continuous data.
For example, consider a...

Summary

Many individuals show nonmonotonic preferences for health durations, preferring shorter durations after a certain point. This challenges standard health economic models and highlights the maximum endurable time phenomenon.

Area of Science:

  • Health Economics
  • Decision Science
  • Psychometrics

Background:

  • Previous research suggests individuals may prefer shorter durations of poor health up to a maximum endurable time (MET).
  • Understanding preferences for health duration is crucial for health policy and economic modeling, particularly for quality-adjusted life years (QALYs).

Purpose of the Study:

  • To empirically test monotonicity in life duration preferences across various health states.
  • To investigate the prevalence of maximum endurable time (MET) preferences and preference reversals.

Main Methods:

  • Employed two ordinal tasks: direct choices and rankings of health episodes combining EQ-5D-3L states and durations.
  • Recruited 90 participants for experimental sessions to elicit and analyze preference patterns.
  • Quantified monotonicity violations and preference reversals between the choice and ranking tasks.

Main Results:

  • Significant rates of nonmonotonic preferences were observed, ranging from 49% (choices) to 71% (rankings) within subjects.
  • Mean nonmonotonicity rates per health state were 22% (choices) and 34% (rankings).
  • Evidence of preference reversals (1.5%-33%) and scarce transitivity violations were found.

Conclusions:

  • Nonmonotonic preferences, particularly the MET phenomenon, are prevalent in mid-range health states.
  • Observed preference reversals suggest potential limitations in using similar response scales for different tasks.
  • Findings challenge the validity of multiplicative QALY models and highlight the need for more nuanced preference elicitation.
