Introduction

The most common and distressing symptoms, which follow anaesthesia and surgery are pain and emesis. The consequences of Postoperative Nausea and Vomiting (PONV) are physical, surgical and anaesthetic complications. It is not just only for patients but also do have financial implications for the hospitals or institutions providing the service [1]. Anesthetic techniques has become considerably safe and changed over time, hence currently anti-emetic is considered as an important part of ‘triads of anesthesia’. Even though the prevalence of PONV was found to be 36.6%, as reported on a study done in this area, prevention and optimal management of PONV remain neglected in the routine anaesthetic part of anesthetic management [2].

There are several international accepted standards recommended for prevention and management of PONV. Consensus guidelines, produced in 2019 suggest treating only higher risk patients with prophylactic anti-emetics which can be estimated based on assessment of four risk factors the guideline does not apply to pregnant women [3]. Treating according to risk will result in better treatment and cost reduction, therefore; this audit is important to identify areas of good practice and gaps where improvements need to be done based on the standards.

Aim

To assess the extent of adaption and application of international consensus guidelines regarding risk assessment and prophylactic management of PONV; whereby to identify the gap and used to improve safe and quality practice of anaesthetic services [4,5].

Objectives

• To identify the number of responsible clinical practitioners who aware of the optimal approach for prevention and therapy of PONV in various patient populations.

• To determine the amount of responsible practitioners who know and use any method to assess risk factors for PONV.

• To describe the ratio of responsible practitioners who used to manage PONV with prophylaxis anti-emetics for high risk patients.

• To find out relative amount of responsible practitioners who adopt with best regimen choice and timing of antiemetic administration.

• To determine the ratio of anesthetists who had just used the optimal approach and anesthetic intervention options to reduce the baseline risks for PONV Figure 1.

Figure 1. Analysis template relative result out puts in graph.

• To improve comprehensive post-anaesthesia care outcomes for patients who just had anaesthesia, sedation or analgesia care Table 1.

Data collection method

Prospective data collection done through subjective sampling and retrospective chart review based on the structured qualitative data collection tool with yes or no interpretation for descriptive analysis (Figure 2A and Figure 2B). Re-audit should also be considered for bringing good progress of implementation and for better patient satisfaction by which; safe Figure 3. Quality and comprehensive anaesthetic services will be improved in the hospital.

Areas of good practice

For all observations of the data set regarding to practitioners need to identify which patients should receive prophylactic anti-emetics during surgery; it has shown significant positive replies, even though it’s not being applied as seen with other standards [5]. Good audit performance results have seen also on guidelines that a clinician shall recognize that for all surgical patients. A PONV risk score should be calculated and one should know determine the optimal choice and timing of antiemetic administration Table 4.

Conclusion

Again satisfactory percent of positive reply meets to the guideline in regard to identifying the most effective antiemetic monotherapy and combination therapy regimens to be best given. There are significantly high gap and markedly less audit performance mainly for three standards set. Which are regarding; one on adoption with how many of the risk factors considered for identifying high risk groups, and the other on the option and practice of optimal anaesthetic approaches in concern with baseline main risk factors. Moreover, considerable gap for a guideline in regard with the routine use prophylaxis anti-emetics to prevent and best manage PONV for high risk patients when indicated.
