Understanding Community Demographics Essay
Health care leaders need to understand community demographics in order to plan for population health including changing demographics across a continuum. On which aspects of the demographic continuum should healthcare leaders focus? Why is this focus important?Understanding Community Demographics Essay
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.Understanding Community Demographics Essay
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
Patient demographics form the core of the data for any medical institution. They allow for the identification of a patient and his categorization into categories for the purpose of statistical analysis. In my work I have found that there are more or less 5 different ways of interpreting the term “demographics.”Understanding Community Demographics Essay
- Date of birth, gender (Ref: Google Health)
- Birth year, gender, country, postal code, ethnicity, blood type (Ref: Microsoft Health Vault: Personal Demographic Information, Basic Demographic Information)
- (A or B) + Contact information (Name, Phone, Address)
- C + Emergency contact information, family doctor, insurance provider data
- (C or D) + Allergies, major diagnoses, major medical history
Now here is the problem: somewhere around item C, the definition of patient demographics starts to get polluted with items such as patient and emergency contact information and patient medical record data. There is a very good reason for this concept drift to have occurred in practice and I’ll break it down as to why it happened.
We can agree that date of birth and gender creates the most classic type of demographic. We can all remember reading news articles about key demographics such as males aged 55-65. Add in ethnicity and some geographical elements such as country and postal code and we have most of the classic of categories. Google Health and Microsoft Health Vault have been careful to adhere to this formal definition.Understanding Community Demographics Essay
In the medical domain, however, there are additional elements that can be used to categorize patients, such as patients with a particular medical condition, allergy or past medical event, e.g. coronary bypass surgery in 1999. I would caution against including these as core demographics though. The reason for this is that they are specific enough that they can be called something else. Even Microsoft Health Vault felt the pressure and included blood type in one of its demographic “things” and this is probably because the term sometimes acts as a catchall and they didn’t know where else to put it.
The term patient demographics, therefore, should be used primarily for the same data items as marketing people use. Everything else has a different name like patient contact information, emergency contact information, family doctor, insurance provider information, etc.
A word of caution though, medical people will almost always include patient contact information when talking about patient demographics. There’s probably no traceable reason why this has happened, but if it helps, patient contact information (+ identifiers) does make it possible to divide the patient population into groups of 1 and this is needed to count how many people belong to the real demographic categories.Understanding Community Demographics Essay
