Abstract
The authors propose a new checklist model adapted for ambulatory oral surgery procedures based on the ‘surgical checklist’ proposed by the WHO. The proposed document contains 18 items divided into two sets: those that must be verified before beginning surgery and those that must be verified after its completion, but prior to the patient’s departure from the site where the surgery is performed. A checklist is an easy-to-use tool that requires little time but provides order, logic and systematization taking into account certain basic concepts to increase the level of patient safety. The authors think that the result is a checklist that is easy to complete and ensures that key patient safety-related matters are dealt with in this field of surgery.
Patient safety has emerged as an important topic in recent years. Although the damage that could be caused by health care has always been known (Hippocrates: ‘ primum non nocere ’), it was not until the 1990s that awareness of the importance and quantification of this problem increased. The classical work by L eape et al. , completed in 1993, demonstrated that, of all adverse events reported, two-thirds were preventable. Another fundamental study that increased awareness about the importance of this problem was the one completed by the Institute Of Medicine (IOM) in 1999, which demonstrated that 44,000–98,000 unnecessary deaths occurred in the USA in 1997. These data led to concern amongst professionals, political organizations and health care authorities, leading to the increase in studies and measures aimed at improving patient safety over the last 10 years.
All the studies indicate the prescription and administration of drugs as a cause for the increased number of adverse events, as well as surgical activity, nosocomial infections and perioperative complications . Since the advent of surgery, there has been an awareness of the potential damage it could cause. The data on surgical complications collected in industrialized nations show that the perioperative death rate is 0.4–0.8%, whilst the rate of major complications is 3–17% . In industrialized nations, nearly half of all adverse events are related to surgical care . Of these cases, at least half are avoidable .
In the light of these data, in 2007, the World Alliance for Patient Safety (which forms part of the World Health Organization) established the ‘Global Patient Safety Challenge: Safe Surgery Saves Lives’ as its second central objective. This change focused on four large topics: the prevention of surgical wound infections, safe anaesthesia, safe surgical equipment and the measurement of surgical services. As a part of this initiative, the World Alliance for Patient Safety launched the ‘Surgical Safety Checklist’ in June 2008. This checklist was proposed as a simple, easy-to-use tool to ensure that key patient safety measures are implemented. The development of this checklist was based on three principles: simplicity, widespread applicability and measurability . These three principles had to facilitate the dissemination of its use around the world.
The checklist’s effectiveness in increasing surgical safety for patients has been greatly demonstrated .
The document presented in the form of the checklist ( Appendix A ) places an emphasis on the need to adapt the checklist to the wide-ranging circumstances, customs and specializations involved in surgical activity . From this perspective, the authors examine its adaptation to the field of ambulatory oral surgery. This activity possesses certain peculiarities that make it different from major surgery in hospitals, the activity that the checklist of the World Alliance for Patient Safety mainly addresses. Some of its special characteristics include the following. First, its ambulatory nature means there is a lack of control over compliance with the preoperative instructions and any possible postoperative complications. Second, is the major use of local or locoregional anaesthesia, sometimes with the support of sedation procedures. Third, the fact that these procedures are performed at many small public and private centres. This dispersion makes it more difficult to collect data on adverse events and spread the culture of patient safety. Fourth, the limited number of health care staff members who usually take part in this type of surgery, for example when anaesthesia is local or locoregional, it is often administered by the professional without the assistance of an anaesthesiologist. The number of auxiliary staff members also tends to be lower than in hospital surgeries and because of this, the presence of an outside observer is infrequent. Fifth, the limited scope of most of these surgical procedures. Although most meet the requirements established by WHO to be defined as major surgery , they tend not to be as invasive as in other fields of surgical activity.
Given these special characteristics, the need arose to adapt the checklist proposed by the World Alliance for Patient Safety to ambulatory oral surgery, thereby respecting the principles of simplicity, ease of use and ‘measurability’. Proposing a checklist that fulfils these conditions and which is adapted to the specific world of ambulatory oral surgery is the objective of this work.
Methods
Proposed document ( Appendix A )
The document contains 18 items that must be verified, some by the auxiliary staff members in charge of the checklist and others by the professional, with a third set verified by both. The 18 items are divided into two sets: those that must be verified before beginning the surgery and those that must be verified after completing it, but always before the patient leaves the premises where the surgery has been performed. Depending on the item in question, the verification must be performed by the dentist and/or the dental assistant (‘dental assistant’ means the clinic’s auxiliary personnel with specific training in dental care) ( Table 1 ).
Items to check before beginning surgery |
1. Verification of patient identity (by the dental assistant and the professional). |
2. Verification of the procedure to be performed (by the dental assistant and the professional). |
3. Verification of the surgery area (by the dental assistant and the professional). |
4. Verification that the clinical background and radiographic records are available (by the dental assistant and the professional). |
5. Verification of the existence of properly completed informed consent documents (by the dental assistant and the professional). |
6. Verification that the operating room has been properly prepared: |
6.1. Surgical area prepared (by the dental assistant and the professional). |
6.1.1. Verification of the asepsis of all surfaces surrounding the patient that may come into contact with the professional’s hands (e.g. handle of a light fixture, handheld items, buttons on equipment, and hoses) (by the dental assistant). |
6.2. Availability of all the surgical instruments necessary for the procedure and verification of its sterilization labelling (by the dental assistant and the professional). |
6.3. Availability of all the materials to be used (e.g. implants, material for grafts, and sutures) (by the dental assistant and the professional). |
6.4. Operation of the mechanical instruments (by the dental assistant): |
6.4.1. Surgical aspiration. |
6.4.2. Rotating instruments. |
6.4.3. Other instruments (e.g. electric, ultrasonic). |
7. In the event of using sedation by medicinal gases: |
7.1. Verifying that the device is working properly (by the dental assistant). |
7.2. Verifying the levels of gas in gas tanks and expiration dates (by the dental assistant). |
8. Verification in the clinical record of prior pathologies and drugs taken by the patient that might interfere during the course of the surgery (by the professional). |
9. Verification of the non-existence of allergies or intolerances that might interfere throughout the course of the surgery (by the professional). |
10. Verification of the patient’s proper compliance with the pre-operative instructions (e.g. antibiotic prophylaxis, anticoagulant treatments) (by the professional). |
11. Verification of the location of and easy access to materials for clinical emergencies (by the dental assistant and the professional). |

17. Verification or the orderly removal of all the potentially contaminating instruments and materials (by the dental assistant). |
18. Reporting of any technical problem detected during the procedure, for its correction (by the dental assistant). |
