Task and Workflow Mapping in Internal Medicine Hospital Departments: Implications for Operational and Digital Transformation in A Large Tertiary Medical Center
This study utilizes structured observational data from a large tertiary medical center to map task distribution and workflow patterns across internal medicine wards, revealing that a significant portion of work consists of non-value-adding activities and misaligned scope-of-practice, thereby providing an empirical foundation for operational redesign and digital transformation.

Imagine a busy hospital ward as a giant, high-stakes kitchen during the dinner rush. You have the head chefs (senior doctors), the line cooks (residents and interns), the dishwashers and prep staff (nurses and aides), and the waitstaff who manage the orders (clerks and support staff).
The goal is to feed the patients (provide care) efficiently. But what if the head chefs were spending half their time washing dishes, and the dishwashers were trying to figure out the secret recipes? That's essentially what this study found.
Here is a simple breakdown of the research, using everyday analogies:
The Big Picture: What They Did
Researchers from Sheba Medical Center in Israel decided to stop guessing how the hospital kitchen worked and started watching it in real life. They didn't just ask people what they thought they did; they stood in the wards for 232 hours (over 9 full days) and wrote down every single action taken by 10 different types of staff members.
They tracked 2,481 individual actions and sorted them into 168 different types of tasks. Think of it like taking a high-speed video of the kitchen, pausing it thousands of times, and labeling every single move.
The Three Types of "Work"
The researchers sorted everything they saw into three buckets, similar to how you might sort chores at home:
- Direct Care (The "Cooking"): These are tasks that actually heal the patient, like examining a wound or deciding on a medication.
- Result: Only 39% of all the time spent was actually "cooking."
- Necessary but Non-Value-Adding (The "Prep and Cleanup"): These are things you have to do to keep the kitchen running, like washing the cutting board, checking the fridge, or writing down the menu. They don't feed the customer directly, but the kitchen can't function without them.
- Result: 43% of the time was spent here.
- Pure Waste (The "Dropped Spoons"): These are tasks that add no value at all, like walking back and forth to find a pen that was lost, or redoing a form because it was filled out wrong.
- Result: 18% of the time was wasted.
The "Chef" Problem: Who is Doing What?
The study looked at whether the right people were doing the right jobs. They used a concept called "Top of License," which is like asking: "Is this person using their full training, or are they doing a job a less-trained person could do?"
- The Senior Chefs (Specialists): They were mostly doing high-level cooking (75% of their time). Good.
- The Line Cooks (Residents & Interns): Here is the problem. Even though they are trained to be chefs, 52% to 79% of their time was spent on "prep and cleanup" (paperwork, coordination, logistics). They were spending more time washing dishes than cooking.
- The Support Staff: Interestingly, some support staff were doing tasks that actually required a doctor's license, while others were doing tasks that didn't require any medical training at all.
The "Pareto" Rule: The 20% That Does 80% of the Work
The researchers found a pattern known as the Pareto Principle (or the 80/20 rule).
- They found 168 different types of tasks.
- However, just 34 of those tasks (about 20% of the types) made up 67% of all the work done in the ward.
What were these top 34 tasks?
They weren't complex medical miracles. They were mostly:
- Distributing meals.
- Talking to patients and their families.
- Updating patient lists on a computer.
- Moving test samples.
- Writing notes.
The Analogy: Imagine a construction site where the master architect spends 70% of their day carrying bricks and sweeping the floor, while the actual design work gets done in the remaining 30% of the time. The study found that hospital wards are full of "architects carrying bricks."
The "Solution Shop" vs. The "Assembly Line"
The study used a framework to describe how doctors work:
- Solution Shop: This is where a doctor uses their brain to solve a unique, complex mystery (like a detective).
- Production Line: This is where a doctor follows a standard recipe or checklist (like an assembly line worker).
The Finding:
- Senior doctors were mostly working in the Solution Shop (solving mysteries).
- Residents and interns were mostly working on the Production Line (following checklists and doing routine tasks).
- 79% of all doctor-related work was "Production Line" work. This suggests that a huge chunk of what doctors do is actually routine and could potentially be done by someone else or automated.
The Root Cause: The "Glue" is Missing
The study concluded that the main reason for this mess isn't that the doctors aren't smart enough or that the patients are too sick. The problem is coordination.
- Informal Chaos: The hospital relies too much on people talking to each other, running back and forth, and remembering things verbally. There isn't a strong system to handle the "prep and cleanup" work.
- Role Confusion: Because the system is messy, highly trained doctors end up doing low-level tasks just to keep the patient moving. They become the "glue" holding the broken system together, which is exhausting and inefficient.
The Bottom Line
The paper argues that to fix the hospital, you don't just need more doctors or better technology. You need to redesign the workflow.
You need to take the "assembly line" tasks (like meal distribution, basic updates, and logistics) and give them to the right people (support staff, technology, or different roles) so that the highly trained doctors can actually focus on the "mystery solving" (diagnosing and treating) that they are trained for.
In short: The hospital kitchen is currently run by the head chef washing dishes. The study says, "Let's hire a dishwasher, give the chef a pen and a recipe book, and let them actually cook."
