Module 1
Prevalence and incidence are a common phenomenon in epidemiology and disease
investigation assessment impact. Prevalence measures a disease condition over a period of
time either at a given point in time of periodic prevalence. Periodic prevalence provides a
better measure of the disease with its load case having new cases and dates between the time
frames. It is often more meaningful when reporting the number of cases as a fraction of the
total population. Incidence measures the rate of new or diagnosed cases of the diseases. It is
beneficial when reported as a fraction of the general populations, (Rotham, Greenland &
Lash, 2008; Woodward, 2013).
In this case, policy formulations are best formulated based on prevalence rates of
obesity. This gives the actual observation of all the live cases during the time of assessments.
Prevalence estimation is key and plays a crucial role in policy formulation. This will inform
assessment on the number of the population likely to face obesity
The second scenario entails the number of the of corona-virus outbreak incidence in
Australia offering meaningful information of the disease occurrence trend. Incidences report
on such diseases establish disease occurrence at a particular point in time. This will be crucial
in offering an assessment of the status of the disease in the population, thus offering a better
approach to the management of the coron-avirus outbreak.
Module 2
Topic 1
Observational studies are designs which offer a description of patterns of disease
occurring in various setups. The descriptive study design will be beneficial in this scenario so
as to assess the association of work-related factors and mental health, (Von Elm et al., 2007).
Descriptive studies are crucial in providing knowledge about workload and mental health.
This design is beneficial in public health fields in assessing segments of populations whom
education and prevention programs can be targeted and further aid in the allocation of
resources to mitigate the health impact being observed.
Topic 2
Title of your research:assessment of new drugs regime offers better nursing outcomes
than generic drugs in cancer management for cancer patients diagnosed with colon cancer.
Intervention: patients diagnosed with cancer with not less than 3 months of medication
history.
The comparator (placebo/active component): administration of new drug regime and
generic drug treatment option for cancer
3
Allocation concealment:the patients will be given a unique number which identifies
then both groups are treated equally and the two groups separated ready for treatment
allocation. The control and cancer group patients will be offered the same treatment options
which are similar in shape, colour, and size which acts as a placebo.
Sequence generation (Random/non-random): random selection of the study subjects
will apply to be applicable in this study assessment
Blinding:The participants will be single-blinded as they will not know which
medications they have been provided. The nursing person in charge will monitor and
document in the checklist patient progress and feedback to assess health outcomes.
Module 3
Topic 1
True positivea=360; this refers to the positives which were correctly labeled as having
the disease
False positiveb=230; these entail the negatives which were incorrectly labeled by the
tests.
False negativesc=390; these entails the positives which were wrongly labeled as
negatives
True negativesd=20;these are true negatives which were correctly labeled by the tests.
Sensitivity = this is a measure of actual positives having the disease which are correctly
identified.
Specificity = this refers to the proportion of actual negatives measurement which is
correctly identified
Sensitivity = A/(A+C) X100

= 360/(360+390)%
= 48%
Specificity = D/(D+B)X100
= 20/(20+230)%
= 80%
Topic 2; surveillance
Disease surveillance is an epidemiological event which the diseases are monitored in
