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...
Longitudinal Studies01:26

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
Methods of Documentation II: POMR01:26

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
Nursing Evaluation01:15

Nursing Evaluation

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Pharmacokinetic–Pharmacodynamic Relationship: Influence of Elimination Half-Life on Effect Duration01:23

Pharmacokinetic–Pharmacodynamic Relationship: Influence of Elimination Half-Life on Effect Duration

Drug elimination from the body primarily occurs through metabolic and excretion pathways. Hepatic metabolism transforms lipophilic drugs into hydrophilic forms for excretion, typically via enzymatic processes classified as phase I (modification) and phase II (conjugation). Renal excretion eliminates drugs and metabolites through filtration and secretion in the kidneys. Impairment in liver or kidney function can hinder these processes, delaying drug clearance and extending the drug’s half-life.
Methods of Documentation III: PIE01:21

Methods of Documentation III: PIE

Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:

Summary

Longer dental externships, specifically ten-week programs, allow dental students to perform more complex procedures and increase weekly procedure volume compared to six-week externships.

Area of Science:

  • Dental Education
  • Community Dentistry
  • Clinical Skills Development

Background:

  • Community-based dental externships are crucial for dental school curricula.
  • Previous qualitative studies indicated increased student confidence, efficiency, and independence in externships.
  • Quantitative evaluation is needed to understand these qualitative findings.

Purpose of the Study:

  • To quantitatively compare the clinical care provided by dental students in six-week versus ten-week general dentistry externships.
  • To investigate the impact of externship duration on the scope and volume of dental procedures performed.
  • To provide data supporting the enhancement of dental externship programs.

Main Methods:

  • A quantitative study comparing clinical care provided by dental students during six-week and ten-week general dentistry externships.
  • Data collection focused on the types and number of dental procedures performed.
  • Comparison of procedures performed per week and overall scope of services between the two groups.

Main Results:

  • The scope of dental services differed significantly between six-week and ten-week externships.
  • Students in ten-week externships performed more complex procedures, particularly later in their rotations.
  • Ten-week externship participants completed more procedures per week than those in six-week externships.
  • Patient visit numbers and procedures per patient did not differ, likely due to site scheduling.

Conclusions:

  • Extended externship durations (ten weeks) facilitate the performance of more complex dental procedures.
  • Longer externships contribute to increased weekly procedure volume, potentially explaining enhanced clinical confidence and skill.
  • Findings support the consideration of longer externships to optimize dental student clinical training and preparedness.
