Longitudinal Research

13.0K
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...

Comparing the Survival Analysis of Two or More Groups

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Summary

Older surgeons are associated with better patient outcomes after surgery. Increasing surgeon age correlated with a decreased risk of death, readmission, and complications, suggesting experience benefits surgical results.

Area of Science:

  • Gerontology
  • Surgical Outcomes Research
  • Health Services Research

Background:

  • Aging may impact cognitive and motor skills, but also brings experience.
  • The interplay of surgeon age and experience on surgical outcomes is not well understood.
  • This study investigates the effect of surgeon age on postoperative results.

Purpose of the Study:

  • To evaluate the association between surgeon age and postoperative outcomes.
  • To determine if older surgeons have better or worse patient outcomes.
  • To analyze the impact of surgeon experience on surgical success.

Main Methods:

  • Retrospective cohort study of over 1 million patients undergoing common surgical procedures in Canada (2007-2015).
  • Examined the link between surgeon age and a composite outcome of death, readmission, and complications.
  • Used generalized estimating equations, controlling for patient, procedure, surgeon, and hospital factors.

Main Results:

  • A 10-year increase in surgeon age was linked to a 5% relative decrease in adverse outcomes (aOR 0.95).
  • Surgeons over 65 years old had patients with 7% lower odds of adverse outcomes (aOR 0.93).
  • The association between surgeon age and reduced adverse events was nearly linear.

Conclusions:

  • Increasing surgeon age is associated with decreased rates of postoperative death, readmission, and complications.
  • Findings suggest surgeon experience, potentially linked to age, improves patient safety.
  • Further research into these mechanisms can inform surgical training, certification, and retirement policies.
