u03a1 Calculations Template
Perform the following calculations. Submit this document as an attachment to assignment u03a1.
1 – Population Description
The following vital statistics are demonstrated within a population:
- Total midyear population = 25,000.
- Population 65+ years old = 2,500.
- Number of live births = 300.
- Total deaths (for all causes) = 250.
- Deaths in infants less than 1 year old = 3.
- Deaths in persons 65+ years old = 75.
Complete the following calculations:
- Birth rate per 1,000 =
- Mortality rate per 1,000 =
- Infant mortality rate per 1,000 =
- Mortality rate for 65+ years old per 1,000 =
2 – Birth and Death Rates
Below you will find information on births in the community served by your system of hospitals.
Complete the calculations for birth rate, overall death rate, and infant mortality rates below:
| Population Size | 255,078,000 |
| Approximate number of live births | 4,065,014 |
| Number of deaths (all ages) | 2,175,631 |
| Approximate number of deaths in infants under 1 year of age | 34,553 |
Note: Show your work (write out your calculations).
- Birth rate:
- Overall dealth rate per 100,000:
- Infant mortality rate per 1,000:
3 – Accidents
The emergency room chief resident at the system’s leading hospital for accidents and trauma believes that the age group comprising persons age 62 and older is the most prone to accidents.The category that holds the second greatest risk is 6- to 14-year-olds.
The chief resident has been collecting the following data on 82 patients who have presented to the ER over the past year and would like you to review and comment.
Review this information and indicate if you agree with the chief. Include a comment regarding the validity of the conclusion (include reasons why or why not):
| Age in Years | Number of Accidents |
| 0–2 | 5 |
| 3–5 | 6 |
| 6–14 | 18 |
| 15–21 | 8 |
| 22–31 | 5 |
| 32–41 | 8 |
| 42–51 | 7 |
| 52–61 | 4 |
| 62 and over | 21 |
Comment on the chief resident’s interpretation of the data:
The chiefs interpretation is quite misleading. From what I gathered, the chief is concluding that indivuduals of age 6-14 and 62 yrs of age or older are more susceptible to car accidents than any other age group, which is not true. Anyone of any age can be prone to an accident. However, I do believe the age groups that chief mentioned might be more susceptible to obtaining more bodily injury assuming the amount of trauma/impact being less than average. In other words individuals of 6-14 and 62 and older age range may have less body resistance than other age ranges surveyed. I do believe that chief’s interpretation would be more agreeable if he would have simply concluded “the average age range of individuals seen in the ER due to accidents are between the age ranges of 6-14 and 62 and older.
4 – Heart Disease
Heart disease is one of the leading causes of death in the United States. One of the hospitals in the system must be evaluated on the prevalence of cardiovascular disease.
100,000 patients are seen annually at the hospital. During the year, 1,000 people died there. Upon review of this information it was determined that 300 of those patients were diagnosed with cardiovascular disease and 60 of those patients died due to cardiovascular disease.
Calculate the prevalence of cardiovascular disease in the hospital.
5 – Hypertension
Hypertension is one of the risk factors for stroke. You have been collecting information on the patients of a hospital who have been exhibiting symptoms of hypertension over the last five years. You had 1,000 male patients aged 40–45.
Complete the following calculations and provide an explanation of your findings:
The study began with 1,000 men (ages 40–45). Of the 1,000 men, 50 are already hypertensive. The remaining 950 are tracked over five years, during which time 64 more men develop hypertension. (Assume there is no loss to follow-up or death due to competing risks).
- Determine the prevalence of hypertension at the beginning of the study.
- 50
- Calculate the five-year incidence proportion (risk) of hypertension.
- Initial: 50
- New: 64×5=320
- Five-year inicidence proportion=320/50=6.4
- Calculate the incidence rate of hypertension in the cohort with and without an actuarial adjustment. Did the actuarial adjustment make a difference? Explain your answer.
- With the adjustment: 320+50=370 370/1000=.37
- Without the adjustment: 320/1000=.32
6 – Infections
Nosocomial infections are on the rise and are costly to the organization. You must calculate the prevalence and incidence of the infections to get a better grasp of what clinical and countermeasures need to be taken at the hospitals.
Complete the calculation below and include a narrative interpreting the results of your calculations.
(Population = 82,438,000)
| Cause of Admission | Number of admits | Proportional Case Ratio (%) | Cause-specific rate per 100,000 |
| Accidents and adverse effects | 26,526 | 21.53 | 32.18 |
| Malignant neoplasms | 22,228 | 18.04 | 26.96 |
| HIV infection | 21,747 | 17.65 | 26.38 |
| Diseases of the heart | 15,822 | 12.84 | 19.19 |
| Homicide and legal intervention | 12,372 | 10.04 | 15.01 |
| Suicide | 12,281 | 9.97 | 14.9 |
| Chronic liver disease and cirrhosis | 4,449 | 3.61 | 5.4 |
| Cerebrovascular diseases | 3,343 | 2.71 | 4.06 |
| Diabetes mellitus | 2,211 | 1.79 | 2.68 |
| Pneumonia and influenza | 2,203 | 1.79 | 2.67 |

Executive Summary – Create a Separate Document
Now that you have completed all of the calculations, develop a two- to three-page executive summary for the annual report detailing the findings on the calculations. Address the following questions:
- Why is this information important to the hospitals in the system?
- What might this information be used for in the organization?
