PDCA vs PDSA, A Quality Improvement Cycle For Hospitals

Every healthcare center such as hospitals seem to work in chaos. But when they adapt to PDSA or PDCA, they happen to improve the quality of their working. They have Plan, Do, Study, Act or they have Plan, Do, Check and Act.

PDCA and PDSA describe the same cycle. The only difference is the third step. PDCA calls it Check: did the change produce the result we predicted? PDSA calls it Study: what did we learn from running the change, including the things we did not expect? The shift from checking to studying is small in wording and large in mindset. Check asks whether a target was hit. Study asks why the result came out the way it did, so the next cycle is smarter. In practice hospitals use both terms, and many quality teams treat PDSA as the more reflective version of the same idea.

Neither cycle is run once. The loop is meant to turn repeatedly, each pass refining the change, which is why both are drawn as circles rather than straight lines. A problem well defined, the workshop teaching goes, is a problem half solved, and the cycle is built to keep sharpening that definition.

The planning phase. The phase one. it is this phase where most work takes place. It is also guide for other phases. Here most of the weak projects fail. It means define the exact problem and find the actual cause before even finding a solution. This includes observation, gathering data, walking the area physically, taking direct responses from the patients, people with them. Through this the evidence can be collected, including photographs. Then the specifics are written down. The who, what, where and when are written down. For eg. If this gets skipped and the team tries to fix a symptom, counselling the night nurse after the process of medication errors, the team might miss the real cause.

Which might be a nurse-to-patient ratio or a distracting ward environment. The seven quality control tools belong here, helping a team move from a vague complaint to a measured, defined problem.

The Do phase is where a chosen solution is generated, selected and implemented, usually as a small pilot rather than a hospital-wide rollout. A pilot keeps the risk contained and the learning fast. If a fast-track lane for routine follow-up patients is the idea, it is tested on one shift or one clinic first, not imposed across the whole outpatient department on day one.

This phase evaluates the pilot’s actual results against what the team predicted. Did the fast-track lane reduce waiting time, and by how much? In PDCA this is a check against the target. In PDSA it is a study: the team also asks what happened that it did not predict, what surprised it, and what that implies. This is the step that separates a genuine improvement from a change that merely felt productive.

The Act phase takes a successful change and makes it permanent: formal protocols, staff training and compliance monitoring. It also includes periodic audits by the quality department, because systems drift back to old habits without them. A change that is not standardised and audited is not an improvement, it is a temporary effort that quietly reverses once attention moves elsewhere.

The clearest way to see the cycle is a rapid PDSA sprint of the kind run at the HOPECON X Jeevan Parul workshop, where Master of Hospital Administration scholars were given live hospital problems and real baselines.

One team selected the outpatient waiting time for a routine consultation for improvement. The baseline average was forty-five minutes, and the target was twenty minutes or less. The day had two peaks of patient complaints that occurred at the first two hours in the morning, and the process waste was connected to the frequent movement of patients from the registration to consultation area. The situation was complicated by the fact that the selected scope for improvement did not allow any additional human resources and significant capital investments. The team designed a new pathway for follow-up patients, including a special fast-track and improved signage, tested it, and started standardizing after verifying that the waiting time met the target of twenty minutes or less.

Another team selected the length of a discharge process. The baseline average was 11:11 in the morning against the target of before 10:30. The team analyzed the volume of discharges on Mondays and Thursdays and found that the duration varied depending on the number of discharges per day. On the Monday in question, there were eighteen discharges, on average, at 10:45. Meanwhile, on Thursday, twenty-two discharges resulted in discharges at 11:40. The length of the process was limited by reconciliation of medications and the readiness of patients’ families to leave. The team planned to implement the discharge process planning at least twenty-four hours in advance and standardized a discharge checklist to be utilized at the start of discharge process in the morning. It can be seen that both projects used the PDSA cycle, utilized data-driven decision-making, and were standardized after being tested against a specific target.

PDCA and PDSA are not academic ornaments. These are practical lessons. The learning is gained through operating method. It is at the accredited hospitals where they are supposed to show how the functioning happens, and how the problems are fixed with a documented process. Students learn the process and learn how to run the cycle. They gain the skills of hospital operations. With this they can define problems precisely, test a change safely, measure the work done till now and lock in what works.

It is also where a business-ready instinct shows up in a clinical setting, a graduate who can see a broken process and build a measured fix around it is the one who ends up improving systems, not just staffing them. Learn about how hospitals work with healthcare management, hospital administration, and BBA in healthcare management.

The improvement cycle is embedded in the quality-management curriculum at the Parul Institute of Public Health and is facilitated through workshops such as HOPECON X Jeevan Parul conducted with the support of the Consortium of Accredited Healthcare Organisations and Parul Sevashram Hospital. Parul University, which is NAAC A++ accredited with a 3.55 CGPA, offers healthcare education with a focus on a functioning hospital system and the Pragya advanced skills and simulation centre, meaning that PDSA sprints can be grounded in actual baselines, not hypothetical scenarios. Dr. Geetika Madan Patel, Vice President and Medical Director at Parul University, views quality and patient safety as integral to a healthcare leader’s education, with the frameworks in question representing public-domain quality concepts that were showcased by visiting resource persons such as Dr. Babu Narayanan and Dr. Dhanya Michael during the event, hosted by Parul University faculty members Dr. Partha Sarthi Ganguly and Dr. Damini Joshi.
