LECT 1: Research question and study design Flashcards
what are the 6 important parts of the health research cycle
burden of disease
mechanisms/associations
efficacy
effectiveness
efficiency
implementation
briefly explain what is meant by studying the “burden of disease”
identify knowledge, number, incidence, prevalence
explain the difference between efficacy and effectiveness
efficacy = ability of an intervention to produce a beneficial effect under ideal and controlled conditions, typically in a clinical trial setting
effectiveness = pertains to the extent to which a healthcare intervention achieves its intended outcomes in routine clinical practice or real-world settings
explain what is meant by efficiency in research
optimal use of resources (e.g., time, money, personnel, equipment) to achieve desired healthcare outcomes
what are the 4 factors than can helpp determine where a research paper is good or bad
quesltiy of the RC
methodology
results
interpretation of results
explain how quality of the research question can determine whether a research paper is good or bad
a good research paper will have a well-defined and clearly stated research question ( apply PICOT framework) that is relevant and important to the field
explain how methodology can determine whether a research paper is good or bad
use appropriate and rigorous methods to answer the particular PICOT research question. This includes using a study design appropriate for the question being asked and collecting and analyzing data in a systematic and unbiased way.
explain how the results can determine whether a research paper is good or bad
present clear and robust results that support the conclusions of the study.
explain how the interpretation of resutls can determine whether a research paper is good or bad
interpret the results in a logical and unbiased way, and it will address the limitations of the study
the objective/aim/purpose/goal of the study is aka
the research question
what is the definition of the general/overall research objective
Describes the “big picture” of what gap in knowledge, this research study is intended to answer
what is the definition of the specific objectives (primary)
Poses the question(s) that will be answered by the study to address the overall research objective
Should be specific and clear
This aim drives the research study plan
what is the definition of the specific objectives (secondary)
Are additional research goals that complement a study’s primary aim(s) by providing additional insights or addressing relatedresearch questions.
e.g., conduct subgroup analyses within the study population to explore whether the primary findings hold true for specific subgroups.
define hypothesis
Statement of what you think the answer to the question will be
Warden SJ, Metcalf BR, Kiss ZS, et al. Low-intensity pulsed ultrasound for chronic patellar tendinopathy: a randomized, double-blind, placebo-controlled trial. Rheumatology 2008; 47:467-71.
from this example state the overall research objective, the specific objective (PICOT) and the hypothesis
Research General Objective:
To compare the clinical efficacy of Low-Intensity Pulsed Ultrasound (LIPUS) to a placebo in the management of patellar tendinopathy symptoms among skeletally mature people
Specific Objective (PICOT):
The extent to which a (T) 12-week course of (I) daily active-LIPUS compared with (C) inactive-LIPUS (placebo) changes (O) pain level of (P) skeletally mature patients with patellar tendinopathy?
Hypothesis:
Pain levels are reduced in patients who receive daily active-LIPUS (treatment) for 12 weeks compared with individuals who receive inactive-LIPUS (placebo)
