Anatomical Positions01:11

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
Chair Conformation of Cyclohexane02:02

Chair Conformation of Cyclohexane

The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is also absent owing to the perfectly staggered arrangement of bonds.
The hydrogen atoms linked to carbons are arranged in two different axial and equatorial orientations to achieve this staggered...

Normal and Tangetial Components: Problem Solving

Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².
Decision Making: Traditional Method01:14

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...
Social Loafing01:37

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated, individuals become less...
Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Summary

Provider posture affects patient time perception in emergency departments. Sitting patients overestimate bedside time, while standing providers lead to underestimation, though interaction quality remains unaffected.

Area of Science:

  • Medical Education
  • Patient Experience
  • Emergency Medicine

Background:

  • Provider posture during patient encounters is a modifiable factor.
  • Understanding patient and provider perceptions of time is crucial for effective healthcare delivery.

Purpose of the Study:

  • To investigate the impact of provider posture (seated vs. standing) on patient and provider time estimations.
  • To assess how provider posture influences patient perceptions of the provider-patient interaction.

Main Methods:

  • Randomized controlled trial involving 224 adult patients and 36 healthcare providers in an academic emergency department.
  • Providers were randomized to sit or stand during initial patient encounters.
  • Patients and providers completed questionnaires; actual encounter times were measured.

Main Results:

  • Patients in seated interactions overestimated encounter time by 1.3 minutes, while those in standing interactions underestimated by 0.6 minutes (P=.001).
  • Providers consistently overestimated time spent with patients, regardless of posture (P=.85).
  • Provider posture did not significantly affect patient perceptions of interaction quality, caring, or understanding.

Conclusions:

  • Provider posture influences patient perception of time spent at the bedside.
  • Seated providers may lead to patient overestimation of time, while standing may lead to underestimation.
  • Provider posture does not appear to impact the perceived quality of the patient-provider interaction.
