•without connections with health care

• A process that can lead to improving healthcare
• Equals Curiosity. “ daily informal researches”
 Questions & Answers”

• Is a part of daily healthcare professional working
 routine directly or indirectly .
Types of Researches
• Experimental: manipulation of variables.
  double blind group assignments “ response to

• Clinical : done is clinical setting. e.g
  randomized control trials.

• Descriptive : describe a group, a situations, or
  individuals. case studies, surveys,
  observation cohort.

• Laboratory: done is lab. setting. e.g basic
  science research

Research is continuous
First step
            Select a topic
            Select a topic
• Working environment (clinical observation,
  problem or challenges).

• Special topic of interest (medical condition of
  self or family member)

• Prior studies. Literature (unanswered
        studies
  question, and how to take it further)

• Study replication for novice to confirm
  previous studies and to generalize if results
  can be applied to other contexts.
Please Note topic is
• Existing knowledge about specific
  essential to determine to research need to be
  done.

• Preliminary literature review is needed to
  examine current information and help refine
  the research question.

• Research project that done without literature
  search might add nothing to the current
  knowledge and will be a waste of time,effort
  and money.

Thus research problem need to be refined by
  literature search to determine what is
  known.
Research problem &
           Question
• start with a general problem & brainstorm to
  refine into a specific focused research
  question.

• Identifying the problem is not an easy task
• what is the question to be answered?
• keep it simple and very defined problem.
• its unlikely that you will make a research
  shattering discovery. But each investigation
  can add a small pice of knowledge
To refine the problem ask
         these question

•How to improve the problem?
•What is known ( in the literature)?
•What is not known ?
•What information of data is needed to
 improve the problem ?
Example 1

A nurse noticed an
unusual number of
postoperative
infection on patients
needing post operative
ventilation.
Purpose of the study ?



Reason for the infection & to minimize
the number of infected patients
Questions to ask ?
• What DATA do we need ? ( medical records, survey
  data from, patients and staff)

• What Variables to consider:
   • Patient related ( Age- type of procedure-
      population ( gender- ethnic group ...etc)

   • Surgical team related ( sterilization, surgical
      skills, antibiotics)

• What ethical issues need to be addressed ?
• Do we need consents from patients, and IRB ?
• Do we need any financial support ? “Grant”
Possible Research questions


• Are there any
  procedural differences
  between infected and
  non infected ?

• Are there demographic
  differences between
  infected and non

• Are there care
  differences?
Example 2
A Research problem
Possible Research
          questions ?
• Information about number of graduate who do
  not practice ( male & female)?

• How many practiced & stopped?
• How many never practiced?
• What are the reasons that made them stop?
• Does type of profession have an impact on
  decision?

• What are the other factors that impact their
  decision ( age, marital status, financial,
What makes a good
       Research Question
• Is it specific enough?
• Does it answer something new or add to the
  field of knowledge or is just replication ?

• Does it build on previous researches? e.g test
  a theory.

• Is it feasible? e.g can you do it? how much
  time, money, staff & interments do you need?

• Is it ethical?
Develop a Research Question
Definition of a Literature Review



•    A survey of articles, books and other
    sources (e.g. dissertations, conference
    proceedings) relevant to a particular
    issue, area of research, or theory.




• A short description & critical evaluation
    of work critical to the topic ( strength
    and weakness)
Successful Literature
         Review :
• Gives overview of the
  available literature on
  the study topic

• Helps to determine
  what is known &
  unknown about topic

• Allow the you identify
  area of controversy

• Formulate questions
  requiring further
  research
