Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
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...
Production Efficiency01:01

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).
Noncompartmental Analysis: Mean Residence Time01:05

Noncompartmental Analysis: Mean Residence Time

According to statistical moment theory, mean residence time (MRT) is an important measure in pharmacokinetics. MRT can be defined as the expected mean of a probability density function distribution. It provides valuable insights into drug disposition in the body.
After the administration of a drug through intravenous bolus injection, the drug molecules are distributed throughout the body and remain there for varying periods. The MRT represents the average time these drug molecules stay in the...
Energy Budgets and Reproductive Strategies00:51

Energy Budgets and Reproductive Strategies

Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
Life Histories01:29

Life Histories

Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...

Summary

Second-year residents evaluated more patients per hour during shorter 9-hour shifts compared to 12-hour shifts. This shift length optimization can increase patient encounters for residents during emergency department training.

Area of Science:

  • Medical Education
  • Emergency Medicine
  • Healthcare Operations

Background:

  • Resident productivity generally increases with training experience.
  • The impact of shift length on resident productivity remains understudied.

Purpose of the Study:

  • To determine if shift length influences the patient evaluation rate of second-year residents.
  • To compare the productivity of residents working 9-hour versus 12-hour shifts.

Main Methods:

  • Retrospective chart review of emergency department (ED) patient encounters.
  • Inclusion of data from second-year residents working 9-hour and 12-hour shifts.
  • Statistical analysis using a 2-tailed t-test to compare patient evaluation rates.

Main Results:

  • Residents working 9-hour shifts evaluated 1.15 patients per hour, versus 1.06 patients per hour for those on 12-hour shifts.
  • Shorter shifts resulted in an estimated 10 additional patients seen per day in a 120-hour coverage ED.
  • This translates to approximately 180 additional patient encounters per resident annually.

Conclusions:

  • Shorter resident shifts (9 hours) are associated with higher patient evaluation rates per hour.
  • Optimizing shift length may enhance resident productivity and increase overall patient encounters in the ED.
