**1. Introduction**

*"To err is human & not to err is not a hype, but an achievable ability"*

Delivering the right care at the right time in the right setting is the core mission of Hospitals. Hospitalization has its inherent complications and medical errors can further compromise patient safety. Institute of Medicine's sentinel report "To Err is Human: Building a Safer Health System" is a worldwide inspiration wonderful [1]. The report advanced patient safety and stimulated dedicated research funding to this essential aspect of patient care. Since then, highly effective interventions have been developed and adopted for hospital-acquired infections and medication safety [2]. Progress and perfection in addressing other hospital adverse events is desirable.

Medical errors are a serious public health problem. Patient safety is fundamental to high-quality patient care. Preventive strategies for patient safety are the need of the hour.

Hospitals provides an opportunity for practicing preventive medicine. Two important areas are (i) to make treatment and hospitalization free from side-effects (like bed rest/immobility complications, nosocomial infections, treatment sideeffects, etc) (ii) obviate medical errors. Although the scope of preventive medicine in hospitals is wide, we need to focus on important issues on priority.

There is growing awareness of the frequency, causes, and consequences of errors as well as side effects in medicine, all for progress for perfection. All this makes it important that we devise workable solutions – the prevention strategies.

*"Trying to ensure the safest possible patient care is as old as medicine itself" 'Primum non nocere' (First, do no harm) is one of the core principles of medical practice.*

#### **1.1 Why hospitals?**

Hospitals should be on the top of priority list. This is because medical errors may occur in different health care settings, and those that happen in hospitals can have serious consequences [3]. Health care organizations are struggling universally to identify and remediate safety-related challenges.
