Genetic Screens02:46

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...
Human Genetics01:28

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...
Genetic Variation01:25

Genetic Variation

Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles, which...
Genomics02:02

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Area of Science:

  • Medical Genetics
  • Healthcare Workflow Analysis

Background:

  • Clinical genetics departments manage diverse activities including patient care and research.
  • Understanding the real-time workflow is crucial for operational efficiency and financial sustainability.

Purpose of the Study:

  • To document the real-time workflow of clinical geneticists and genetic counselors in a general genetics department.
  • To analyze time allocation across patient care, research, and administrative tasks.

Main Methods:

  • Physician geneticists and genetic counselors used an electronic tool to record activities in 15-minute increments.
  • Data collection occurred over a 10-week period, including clinic hours, evenings, and weekends.

Main Results:

  • Physicians averaged 54.1 hours/week, genetic counselors 43.5 hours/week.
  • Physicians spent ~25% of clinic time on direct patient care, ~25% on other patient-related activities, and ~25% on research.
  • Genetic counselors dedicated 50% of their time to patient-related activities, including 25% to direct patient care.

Conclusions:

  • Clinical genetics is labor-intensive, with significant time dedicated to patient-related activities.
  • Limitations in genetic counselor billing contribute to the financial challenges in genetics departments.
