World Patient Safety Day is observed every year on September 17. This day is declared by the World Health Organisation (WHO) to raise awareness about patient safety, promote actions to enhance safety in healthcare, and encourage stakeholders to unite for safer healthcare practices. Why Is It Important?This day also recognises the significant burden of harm that unsafe medical practices cause worldwide. Thus, it highlights the need for improved healthcare systems, practices and methods that prioritise the well-being of patients. An estimate of 134 million adverse events that occur annually in hospitals in low-and-middle-income countries, patient safety is crucial to reduce preventable harm and deaths. ThemeThis year's theme is "Improving Diagnosis for Patient Safety" with the slogan of "Get it Right, Make it Safe!"Diagnostic Safety has many aspects to it: Correct treatmentAn accurate diagnosis is crucial to determine the correct treatment. A delayed diagnosis or an inaccurate one can result in the patient not receiving the necessary medical care, which can lead to further health problems or complications. Unnecessary treatment or the prescription of medication that is not necessary can pose significant health risks.Early detection of diseases:An accurate diagnosis enables early detection of diseases. This can help treat serious health problems at an early stage, which improves the chances of recovery and can reduce healthcare costs.Resource efficiencyAn accurate diagnosis helps to use resources more efficiently. Medical resources such as time, personnel, equipment and financial resources can be used more effectively when the diagnosis is certain and accurate.TrustA reliable diagnosis helps maintain patients' trust in the healthcare system and healthcare professionals. A loss of trust can lead to uncertainty, dissatisfaction and poorer compliance with medical instructions.Patient participationWhen patients understand that their diagnosis is correct, they are more willing to actively participate in their own healthcare. This includes adhering to treatment plans, implementing lifestyle changes and collaborating with the treatment team.HistoryIn 2019, the 72nd World Health Assembly passed a resolution to establish World Patient Safety Day as a global health priority. This started WHO's global campaigns every year that focussed on various themes within patient safety such as safe childbirth, medication safety, and empowerment of patients, etc. SignificanceThis day raises awareness and educates policymakers, healthcare professionals and general public on the importance of medical safety. It also advocates for prevention of errors, and reduction of preventable harms and promotes a patient-centric care culture. Furthermore, it transcends boundaries, being a global campaign, it highlights issues across the globe, seeks global collaboration and advocates for strengthened healthcare systems.
