Background: Preoperative anxiety is a common occurrence in patients presenting for surgery with a reported incidence of up to 80%. Increased preoperative anxiety has been associated with increased morbidity. Provision of information relating to surgery and anaesthesia to patients has been proven to have benefit in allaying anxiety. However, the best format of information dissemination remains unknown. Objective: To determine the effect of video information in addition to the pre-anaesthetic review on the mean preoperative State anxiety inventory (STAI-S) score in adult patients presenting for elective caesarean section under spinal anaesthesia at Aga Khan University Hospital, Nairobi (AKUHN), and to determine the prevalence of preoperative anxiety in the obstetric population presenting for elective caesarean section at AKUHN. Methods: Thirty-seven adult patients booked for elective caesarean section under spinal anesthesia were randomly assigned to one of two groups. In the study arm; a video was shown to the participants in addition to the standard pre-anaesthetic review. In the control arm the participants only had a standard pre-anaesthetic review. Results: The mean STAI-T score in the sampled population was 45.64 (SD 5.625). The mean baseline STAI-S score was 46.32 (SD 4.911). There was no statistically significant difference in change in STAI score between the video and control arms (p>0.05). Conclusion: On the basis of this study among this population, there was no benefit demonstrated from the use of an information video about spinal anaesthesia on anxiety levels in obstetric patients presenting for a first time spinal. Keywords: Video-based information; anxiety inventory scores; elective caesarean section.

ObjectivesThe use of preoperative triage questionnaires is an innovative way to mitigate the shortage of anaesthesiologists and to identify and refer high-risk patients early for evaluation. This study evaluates the diagnostic accuracy of one such questionnaire in identifying high-risk patients in a Sub-Saharan population.DesignDiagnostic accuracy studySettingThe study was conducted in a preanaesthesia assessment clinic in a tertiary referral hospital in Sub-Saharan Africa.ParticipantsThe study had a sample size of 128, including all patients above the age of 18 scheduled for elective surgery under any modality of anaesthesia other than local anaesthesia presenting to the preanaesthesia clinic. Patients scheduled for cardiac and major non-cardiac surgery and those non-literate in English were excluded.Outcome measuresThe sensitivity of the preanaesthesia risk assessment tool (PRAT) was the primary outcome measure. Other outcome measures were specificity, positive predictive value and negative predictive value.ResultsMajority of patients were young and women with a mean age of 36 referred for obstetric and gynaecological procedures. The sensitivity of the PRAT in identifying high-risk patients was at 90.6% with 95% CI (76.9 to 98.2) in this current study while the specificity, negative predictive value (NPV) and positive predictive value (PPV) were 37.5% with 95% CI (24.0 to 43.7), 92.3% with 95% CI (77.7 to 97.0) and 32.6% with 95% CI (29.6 to 37.3) respectively.ConclusionThe PRAT has a high sensitivity and may be used as a screening tool in identifying high risk patients to refer to the anaesthesiologist early before surgery. Adjusting the high risk criteria to fit the anaesthesiologists’ assessments may improve the specificity of the tool.
