Prior to beginning work on this assignment, please review the related grading rubric.

For this assignment, you will complete the Chapter 8 Case: Control of “thresholds for evaluation” (TFE’s) at Hallenvale Hospital and Chapter 9 Discussion Question 7, parts b, c, and g.

Control of TFE’s at Hallenvale Hospital Case

This case requires you to assess the infection rate at the hospital and do the following:

  • Calculate the average percent of infections.
  • Create an appropriate control chart with upper and lower control limits, plot the data in a Control Chart (using Excel), and determine if the process is in control.
  • Determine what actions management should take.
  • Determine an appropriate TFE for management to use to monitor future data.

Question 7

These questions require that you evaluate different approaches to improving process performance and develop a recommendation on how to proceed. The question and its parts are listed below. Identify and discuss what would be the most appropriate tool (e.g., 7 QC Tools used for kaizen or others) to use to attack each of these problems:

B. The publication team for an engineering department wants to improve the accuracy of its user documentation but is unsure of why documents are not error free.

C. A rental car agency is getting numerous complaints about the length of time that customers have to wait to obtain a car. They need to get a better handle on the factors that relate to the wait time.

G. A travel agency is interested in gaining a better understanding of how call volume varies by time of year in order to adjust staffing schedules.

In your recommendations for each scenario, examine techniques (e.g., a Six Sigma technique, “lean” strategies, etc.) to improve input and supplier quality, and incorporate a customer-focused approach to Quality Management concepts.

Each conclusion should incorporate at least one scholarly reference supporting the recommendations made. Across the three recommendations, use at least three scholarly sources in addition to the text.

Calculate the average percent of infections

An average is a single number taken as representative of a list of numbers. Different
concepts of average are used in different contexts. Often "average" refers to the arithmetic mean
which is the sum of the percentage (%) infections divided by how many infections cases were
reported in that period. In the case provided, the sum of the percentage number of surgeries
conducted which is 24.83% and the total infections is 55 i.e. 24.83%/55=0.45%.

Determine what actions management should take

The management should acknowledge the fact that an infection may begin at the incision
or in the blood and areas surrounding the incision. Patients undergoing surgeries may also
experience infections unrelated to the surgery undergone such as the urinary tract infection (UTI)
after undergoing a gallbladder surgery. Such infections may be attributed to the use of urinary
catheter during surgery procedures. The management should ensure high hygiene levels in the
surgery rooms and hospital environment. Policies that back such initiative may include strict
adherence to washing hands using antibacterial soaps to anyone visiting the patient rooms. An
Antibacterial Hand Cleanser may ...
