Question

discuss the advantages and disadvantages of the type of statistical analysis used in the study napping on the night shift a two hospital implementation project. support your discussion with examples from the study

Answer 1

Article: Napping on the Night Shift: A Two-Hospital Implementation Project.

The article discusses sleepiness issues with the nurses who work on the night shift and benefits of scheduled naps as an effective counter-measure. The article describes the results of a napping implementation project that was conducted in two hospitals.

Analysis methods used:

• Karolinska Sleepiness Scale - a nap experience form to assess
  • pre-nap sleepiness levels
  • nap duration
  • perceived sleep experience
  • post-nap sleep inertia
    • perceived helpfulness of the nap

• Descriptive statistical parameters used:
  • Standard deviation of the measured continuous variables like nap duration
  • Average or mean values
  • Mean KSS score

In a case-control study, causes of sleepiness issues are investigated after the occurrence of a sleepiness issues.

Advantages of using hospital of napping on the night shifts people controls in case-control studies include:

• As the hospital records of the napping on the night shift people are readily available which contains all the information,the findings can be obtained quickly.
• Only minimal funding will be needed as the study takes place in a hospital where the napping on the night shift people under study stay in the same premises.This will reduce the cost of travel.
• The study is conducted on a napping on the night shift people,using hospital patients as control is very efficient, as it helps to study diseases which have long latency period between exposure and napping on the night shift people manifestation.
• When exposure data is expensive or hard to obtain this method of using hospital patients is very useful as data is easily available for these napping on the night shift peoples.
• The follow-up of the study becomes easy when using hospital of napping on the night shift peoples as it reduces the time and travel needed to find the subjects under study.

Disadvantages of using hospital of napping on the night shift peoples as controls in case control studies include:

• One cannot generate a proper incidence data because the population under study is limited to those in the hospital only.
• There can be selection bias when selecting control group.
• If the record keeping of the hospital of napping on the night shift peoples involved in the study is either inadequate or unreliable it will become difficult to conduct the study.
• the selection of controls(hospital of napping on the night shift peoples) can be difficult,depending on whether the patient is willing to participate or not.
