Read The Following Case Studyben Davis Had Just Completed An Intens
Read the following case study. Ben Davis had just completed an intensive course in Statistical Thinking for Business Improvement, which was offered to all employees of a large health maintenance organization. There was no time to celebrate, however, because he was already under a lot of pressure. Ben works as a pharmacist's assistant in the HMO's pharmacy, and his manager, Juan de Pacotilla, was about to be fired. Juan's dismissal appeared to be imminent due to numerous complaints, and even a few lawsuits over inaccurate prescriptions.
Juan now was asking Ben for his assistance in trying to resolve the problem, preferably yesterday! "Ben, I really need your help! If I can't show some major improvement or at least a solid plan by next month, I'm history." "I'll be glad to help, Juan, but what can I do? I'm just a pharmacist's assistant." "I don't care what your job title is; I think you're just the person who can get this done. I realize I've been too far removed from day-to-day operations in the pharmacy, but you work there every day.
You're in a much better position to find out how to fix the problem. Just tell me what to do, and I'll do it." "But what about the statistical consultant you hired to analyze the data on inaccurate prescriptions?" "Ben, to be honest, I'm really disappointed with that guy. He has spent two weeks trying to come up with a new modeling approach to predict weekly inaccurate prescriptions. I tried to explain to him that I don't want to predict the mistakes, I want to eliminate them! I don't think I got through, however, because he said we need a month of additional data to verify the model, and then he can apply a new method he just read about in a journal to identify 'change points in the time series,' whatever that means.
But get this, he will only identify the change points and send me a list; he says it's my job to figure out what they mean and how to respond. I don't know much about statistics -- the only thing I remember from my course in college is that it was the worst course I ever took-- but I'm becoming convinced that it actually doesn't have much to offer in solving real problems. You've just gone through this statistical thinking course, though, so maybe you can see something I can't. To me, statistical thinking sounds like an oxymoron. I realize it's a long shot, but I was hoping you could use this as the project you need to officially complete the course." "I see your point, Juan.
I felt the same way, too. This course was interesting, though, because it didn't focus on crunching numbers. I have some ideas about how we can approach making improvements in prescription accuracy, and I think this would be a great project. We may not be able to solve it ourselves, however. As you know, there is a lot of finger-pointing going on; the pharmacists blame sloppy handwriting and incomplete instructions from doctors for the problem; doctors blame pharmacy assistants like me who actually do most of the computer entry of the prescriptions, claiming that we are incompetent; and the assistants tend to blame the pharmacists for assuming too much about our knowledge of medical terminology, brand names, known drug interactions, and so on.
It sounds like there's no hope, Ben!" "I wouldn't say that at all, Juan. It's just that there may be no quick fix we can do by ourselves in the pharmacy. Let me explain how I'm thinking about this and how I would propose attacking the problem using what I just learned in the statistical thinking course."

The case study presents a complex problem involving prescription inaccuracies within a healthcare organization, emphasizing the need for a strategic approach rooted in statistical thinking to effect meaningful improvements. Ben Davis, recently trained in statistical thinking for business improvement, seeks to address this pervasive issue by applying principles learned in his course, focusing less on raw data analysis and more on systemic and process-oriented solutions.
The primary challenge lies in the interdepartmental finger-pointing among pharmacists, doctors, and pharmacy assistants, which has hindered effective problem-solving. Traditional approaches, such as predictive modeling mentioned by the external consultant, have failed to yield actionable insights, especially since their focus was on forecasting errors rather than eliminating them. This highlights a fundamental aspect of statistical thinking: understanding variability and root causes rather than just outcomes. Statistical thinking encourages a shift from reactive to proactive problem-solving, emphasizing understanding process variation and identifying systemic issues that contribute to errors.
Ben's perspective indicates a need to adopt a holistic, systems-based approach aligned with statistical thinking principles. He recognizes that prescription errors result from multiple sources, including handwriting legibility, incomplete physician instructions, pharmacy entry processes, and assumptions about medical knowledge. Therefore, interventions should target the entire process rather than isolated symptoms. Techniques like process mapping, root cause analysis, and control charts can be instrumental in recognizing patterns and inconsistencies, providing insights that lead to targeted improvements.
For instance, implementing standardized prescription formats and training can reduce variability caused by handwriting issues. Incorporating checklists or automated verification systems can minimize human errors during data entry. Furthermore, fostering collaborative communication among pharmacists, doctors, and assistants can clarify expectations and responsibilities, dismantling blame culture and promoting shared accountability. This aligns with the statistical thinking principle of viewing the process as a system and seeking to alter or improve that system rather than merely punishing individual errors.
Additionally, tracking process performance through control charts can identify specific points in the workflow where errors spike, revealing systemic vulnerabilities. Such data-driven insights help management decide where to focus resources for maximum impact. Continuous monitoring allows for iterative improvements, fostering a culture of learning and adaptation rather than blame.
In essence, the approach proposed by Ben combines statistical thinking with operational strategies, emphasizing understanding the process, reducing variability, and fostering collaboration. While data collection and advanced modeling may be valuable, initial steps should prioritize systemic analysis, process control, and communication improvements. This methodology not only addresses immediate errors but also establishes a sustainable framework for ongoing quality improvement in the pharmacy, ultimately leading to reduced inaccuracies and enhanced patient safety.
