Albert Einstein had quoted that “Wisdom is not a product of schooling but of the lifelong attempt to acquire it” AND I say, it is only possible when data are translated to information, which is then used or practice, then they generate knowledge, and when knowledge is practiced or applied regularly; then WISDOM prevails. Instead of theoretical jargons, I am illustrating a simple example based on my experiences during my surgical practices more than 17 years ago.
Data (Input) to Information (Output) – Problem identification to verification
Most of the cases of all surgical units were experiencing post-surgical wound infection. Everyone was aware of this problem, but no one had identified the exact causes of the outbreak of wound infection. After a couple of days of intensive literature review and observation, I suspected that the cause of these infections was due to some flaws in patients’ preoperative preparation. Usually, nurses prepare patients with preoperative fasting, sedation and shaving of the surgical sites a day before. I suspected the shaving of a surgical site a day before the surgery could be a primary reason for these infections. Even though they followed the best practices for preoperative procedures, the shaving always causes invisible minor injuries in skins. These invisible injuries were a favorable environment for microbes to grow overnight, which was further aggravated by hospital wards’ dire situation in terms of cleanliness and lack of practice of patients taking shower a day before the surgery.
I interpreted the cause of the wound infection to our unit chief and mentioned that I would like to change the procedures of preparation of surgical cases. After receiving a green signal from the chief, I immediately made some minor changes in the pre-operative preparation of surgical patients in our unit. Usually, each medical officer had to stay overnight in the hospital a day before the unit’s routine surgery day. This was to ensure that all surgical cases were well prepared for the surgery the next day.
I stopped preoperative shaving of each patient a day before and requested to do shaving one to two hours before surgery in our unit. This decision served as a case-control study between units too. The results were amazing, with nearly zero wound infection in the unit. Very few post-surgical wound infections were observed in the unit compared to others. I didn’t conduct any statistical analysis or hypothesis testing.
These data and information identified the followings: i) WHAT is the issue and factors for wound infection, ii) WHO are affected or responsible for, iii) WHEN did it happen, and iv) WHERE the problem was.
Knowledge (outcome) to Wisdom (impact) – Practiced changed and instituted.
The results of before and after changing the shaving practices after comparing with other units were so convincing that the entire surgical department believed my hypothesis to be correct and decided to change the surgical site’s preoperative shaving to one to two hours before surgery. This led to a dramatic decrease in wound infections in the entire department. This practice prevented forming a favorable environment for bacterial growth. Pre-operative cleaning with iodine solution before surgery in a surgical site also complemented creating an unfavorable environment for bacterial growth. Therefore, reducing the complications and hospital stay.
Knowledge developed (HOW): Stopping to shave a day before and shaving only 2 hours before the surgery
Wisdom Prevailed (WHY): To reduce the surgical wound infection and reduce the hospital stay and the cost of patient and hospital staff.
If data and information are like a look back to the past, knowledge and wisdom are related to what we do at present and what we want to attain in the future. This example demonstrated how the data, information and knowledge help to understand the context.
