Qualitative / Qunatitative Flashcards
Qualitative
Exploratory research
Subjective, interviews with professors
Quantitative
Based on externals and objective measurements
Statistics
Main styles of qualitative research
Biography
Phenomenology - “lived experience” or phenomenon
Case study: in depth study of a single person or group
Applications of research in healthcare:
Impacted of illness and treatment Sales and marketing Patient education Patient and provider behavior Law and policy Patient satisfaction
Limitations of qualitative research
Time consuming
Internal reviewing adds more time labor and costs
Difficulty with sharing data
Anonymity is a challenge
Info may not be trustworthy
Styles of quantitative research (design)
Observational: correlational research without intervention (epidemiological)
Quasi-experimental: resembles the experimental research but lack allocation of groups or proper control. Lacks randomness, ex: affect of alcohol consumption on pregnant women- unethical
Experimental: study in which a treatment, procedure or program is intentionally introduced as a result or outcome is observed
3 components:
- Random
- Control group
- Experimental group
Styles of quantitative research (temporal cycle)
Retrospective; use of data or specimens existing at the time the research is beating submitted
Cross-sectional: collects data at a single point in time
Prospective: formulation of a hypothesis a collection of data over a defined period of time and then analyzing findings -looking forward
Limitations of qualitative research in healthcare
Time and cost are greatest limiting factors
Generalizability - only do experiment on a small population that is generalized into total population
Source of bias
1: sampling -selecting a subset of population and recruiting tp participate in the study
- Measurement - selection bias, self-reporting bias, recall bias
- Other sources of bias
Publication - finding against norm, not published
Funding bias
Lack of clinical significance
Case series/reports
Collection of reports on the treatment of a single patient or a report on a single patient
Quantitative
Case control
Quantitative
Patients who have a specific condition are compared with people who do not have the condition
Control group!!
Prospective
Retrospective
Cohort study
Identify group of patients who are already taking a particular treatment or have an exposure
“Group of possible subjects who would be feasible to follow prolonged period”
“Inclusion criteria”
RCT
Study design that randomly assigns participants into an experimental group or control group
“Randomly assigned”
Placebo group
Double blind is best
Systematic review
Summarizesthe results of available carefully designed healthcare studies (controlled trials) and provides a high level of effectiveness of healthcare interventions
“Specific search engines”
“We searched…”
Meta analysis
Statistical analysis of a large analysis of the individual studies to integrate the findings
Take several systematic reviews and statistical analysis
“Says meta analysis”
4 phases of clinical trial
Phase I: researches test on experimental drug in small group (20-80)
Phase II: trials the experimental study drug or treatment is given to larger group (100 to 300)
Phase III: group is even larger (1,000-3,000)
Phase IV: trials, post marketing studies provide additional information
