How to Use Math in Health Care Careers
Health care professionals use math to complete a variety of medical functions. These functions range from simple data collection to complex statistical computations. Although the type of math used varies within each specific health career role, a firm grasp of mathematical principles is needed to help avoid medical error. Learning the ways that math is used in health care gives you a better understanding and appreciation for the skills needed to maintain a safe health care environment.

Take accurate measurements. Using the appropriate equipment and measurement systems is essential to gathering patient information. Know the standard units used in each collection process. For example, patient weight is generally recorded in pounds. Use conversion formulas as necessary to ensure that data is congruent. For example, use the formula C x 1.8 + 32 to convert a Celsius temperature to a Fahrenheit reading. Learn the metric units and their English system equivalents for effective conversions. Enter information into patient logs for ongoing assessment and analysis. Licensed practical nurses and certified nursing assistants commonly use this type of computational math.

Calculate medication dosages. Read the dosage guidelines to determine standard dosage ranges for the given medication. Use an accurate scale to measure the patient's weight. Enter the resulting weight into the given equation to determine the appropriate amount of medication to administer. Make conversions as necessary to conform to the equation. Although weight is generally expressed in pounds, it may be simpler to convert the measurement into kilograms. Ask another team member to verify your computation to prevent medication error. Learn the ratio/proportion method as well as the dimensional analysis method for greater confidence and accuracy in your computations. Doctors, registered nurses and pharmacists commonly use this type of computational math.

Assess laboratory tests. Compare patient test results to standardized normal values to determine abnormalities and rule out diseases. Collect and deliver an adequate amount of a patient specimen for testing. Read the analysis report, and take note of any abnormal values. Consider the degree of variation from normal present in each result. Use this information to make treatment and medication decisions. Doctors and specialists commonly use this type of comparative math.

Predict staffing needs. Track the number and "needs" levels of patients in specific units for predetermined amounts of time. The periods should cover at least one week. Find the average number of patients during each day to predict how much staff is needed to accommodate them in a 24-hour period. Scrutinize the admission and discharge times to help divide team members into appropriate shifts. Divide the total number of shift patients between the staff members. Heath care managers commonly use this type of statistical and analytical math.

Monitor facility culture. Query results for total, unique and new-patient encounters to assess the level and type of client growth. Use previous reporting-period data as a baseline for assessment. Compare these new numbers with industry averages to determine your ranking. Use these numbers to create business strategies. Health care managers and officers commonly use this type of statistical and analytical math.
