Prevalence of preoperative anxiety and its contributing factors in adult patients undergoing elective orthopaedic surgery at an academic hospital in South Africa: a pilot study

Preoperative anxiety potentially results in perioperative anaesthetic complications. This study aimed to determine the prevalence of preoperative anxiety in adult patients scheduled to undergo elective orthopaedic surgery at an academic hospital in South Africa and identify contributory factors. Methods: This cross-sectional study included all patients scheduled for elective orthopaedic surgery the following day from 25 July to 3 November 2021. An adapted version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) was used. Four questions determined the patients' anxiety and two questions their desire for more information about their forthcoming anaesthesia and surgery. A 5-point Likert scale was used to capture the patients' responses to the APAIS questions. Data on other possible contributory factors to preoperative anxiety were collected using a questionnaire. Results: Of the 88 patients, 82 (93.2%) were included in the study. A total of 40 (48.8%) patients had an APAIS score of ≥ 11, indicating anxiety. A high need-for-information score (≥ 8) was found in 31 (37.8%) patients. A significant association between patients with a higher anxiety score and a higher need-for-information score (p = 0.0063) was identified. Other non-significant factors associated with a higher anxiety score included a lower level of education and no postoperative home support. Conclusion: Patients with a high need for information tended to be more anxious on the day before surgery. The APAIS could be introduced in preoperative ward admissions to identify these patients and provide an appropriate level of counselling about their planned procedure. Counselling might reduce their preoperative anxiety, but further research needs to confirm this assertion. Larger studies are recommended to determine the influence of other factors contributing to preoperative anxiety

A prospective descriptive study on emergency medicines used most frequently from the emergency medicine packs at Universitas Academic Hospital and the associated financial loss of expired emergency medicines

Resuscitation trolleys with equipment and medicines for emergencies are required in all clinical areas in hospitals. Emergency medicines kept separately are more likely to expire than non-emergency medicines, as these are generally used less frequently. An updated list of essential emergency medicines was implemented in 2016 at an academic hospital in central South Africa. The aim of this study was to determine the frequency of both the use and the expiry, with associated financial losses, of the emergency medicines on this list. Methods: A prospective, descriptive study was conducted over a six-month period in 2019. Forms accompanying the emergency packs were returned to the pharmacy whenever packs expired or were opened. These forms were collected and the type and quantity of medicines either used or expired were recorded. Results: In total, 168 of the returned forms were included. The most frequently used emergency medicines were adrenaline, sodium bicarbonate and Ringer's lactate. Adrenaline use was recorded on 52.8% and 25% of the forms from the adult/paediatric and neonatal emergency packs, respectively. Medicines that were never used included: betamethasone, Darrow's half-strength solution and most of the neonatal pack medications. Neonatal emergency medicine packs were rarely used and the neonatal fluid packs were never used. The total cost of the expired medicines was R7 960.29 (US$569.41 at the time of the study). Adrenaline was the medication that expired most frequently but the greatest financial losses occurred from expired sodium bicarbonate. Conclusion: The total financial losses were low but can be reduced further. The contents of the emergency packs should be reviewed to possibly reduce the amount of items used infrequently. Also, the removal of those items not recommended in emergency care guidelines could be considered. Ensuring the policy was followed of returning unused medicines close to expiry and redistributing these to high-use areas would further reduce wastage

Steps walked whilst at work, by University of the Free State medical registrars: an exploratory study

Background: Doctors may have physical disabilities affecting their mobility. If they wish to specialise, they need information regarding mobility requirements for various specialities to help them select an appropriate speciality. No research has been published on the differences in physical activity demands in different medical specialities. Objective: The aim of this study was to compare the physical activity of medical registrars from six specialist departments at a South African academic hospital. The inference was that those specialities where registrars walked the most would be more challenging for those with physical disabilities, thereby limiting mobility. Methods: The number of steps walked from 07:00 to 16:00 each day was measured, using Yamax CW-701 pedometers. Kruskall-Wallis tests were used to compare the steps taken in different specialities with the level of significance set at 0.05. Results: Twenty registrars participated in the study. Significant differences in the number of steps walked per day were observed between those from different specialities (p < 0.001). Surgery, paediatric and internal medicine registrars walked the most steps per day (median of 5 991, and 5 880, 5 489, respectively). Anaesthesiology and radiology registrars walked a median of 4 521 and 3 926 steps, respectively. Registrars in obstetrics and gynaecology walked the least steps (median of 1 918). There was considerable variation in steps between participants within a department, and for the same participants on different days. Conclusion: Registrars appeared to be more physically active in some medical specialities than others, in terms of mobility. The wide intra-speciality variation is probably related to differing daily duties. Future studies should include types of work duties (e.g. sedentary vs high physical mobility), cover more specialities, and include more participants.

Intravenous paracetamol ­ waste not, want not: a retrospective audit on the appropriate use of intravenous paracetamol at Universitas Academic Hospital Complex­Bloemfontein

Background: Paracetamol can be given both orally and intravenously (IV) with similar clinical efficacy, but the IV formulation is 360 times more expensive. IV paracetamol is therefore only recommended when the oral route is not available. This study investigated whether IV paracetamol was being used appropriately and whether there had been a change in prescribing patterns between 2008 and 2015 after the introduction and update of a prescribing protocol at an academic hospital complex in Bloemfontein, South Africa. Methods: A retrospective comparative audit of patient files was undertaken. The prescribing and administration habits of IV paracetamol were compared for two consecutive months, seven years apart, including 88 and 83 patients, respectively, who had received IV paracetamol. Results: IV paracetamol was administered appropriately in 37.5% of patients in 2008 and in 43.4% of patients in 2015 (p = 0.43). There was an improvement in the duration that IV paracetamol was prescribed for, which decreased from a median two days in 2008 to one day (p < 0.01) in 2015. In total, 55 (32.4%) patients had a concomitant oral and IV paracetamol prescription, of which 37 (21.6%) patients also received concomitant paracetamol administration. Twenty patients exceeded the 24-hour maximum dose. Seventeen patients weighed less than 40 kg; six of these patients (three paediatric and three adult) did not receive the correct weight adjusted dose of paracetamol, 15 mg/kg, resulting in excessive doses of paracetamol being administered (21­ 32.3 mg/kg). Conclusions: Patients are receiving IV paracetamol when the oral route is available; this is an unnecessary waste of money. Excessive doses of paracetamol were administered due to concomitant oral and IV paracetamol prescription and administration, and a failure to calculate dose of paracetamol according to body weight in low body weight patients. Further remedial interventions are therefore required

Preoperative fasting times: Prescribed and actual fasting times at Universitas Hospital Annex, Bloemfontein, South Africa

Background. Guidelines recommend a preoperative fasting period of 6 hours for solid food and 2 hours for clear fluids. Because of fixed meal times and imprecise operation starting times, patients often fast for an extended period of time.Objective. To investigate the prescribed preoperative fasting times, and the actual duration of fasting, compared with the internationally accepted fasting times for solid food and clear fluids.Methods. Patients (N=105) aged 14 - 60 years, who were scheduled for elective surgery in the morning session (list starting time 07h00), were included in this prospective study. On arrival in theatre, all patients were asked when they last ate and drank. Anaesthetic records were used to determine the prescribed fasting times and operation starting times. Results. For solids, patients were most frequently prescribed to start fasting from 22h00 to 00h00 (53.3% and 39.1%, respectively). No patient fasted <8 hours. The median duration of fasting was 14 hours and 45 minutes (range 9 hours and 45 minutes - 19 hours and 5 minutes). For fluids, patients were most frequently prescribed to start fasting from 05h00 (46.7%), 00h00 (27.6%) and 22h00 (7.6%). In practice, no patient ingested fluids after 22h30 or <9 hours preoperatively. The median fasting time for oral fluids was 13 hours and 25 minutes (range 9 hours and 37 minutes - 19 hours and 5 minutes).Conclusion. Most patients started fasting too early preoperatively, consequently withholding food and oral fluids for longer than recommended. An increased awareness regarding complications of unnecessarily long fasting times, and interventions to correct this problem, is required

'Look and Lletz/' ­ a Chris Hani Baragwanath Hospital experience

Objectives. An audit was undertaken of a 'colposcopy and treatment' clinic between April 2003 and December 2006; to determine: (i) the frequency of overtreatment with Papanicolaou smear on its own; colposcopy on its own or a combination of the two methods; (ii) differences in overtreatment between patients who are HIV positive and those who are HIV negative; and (iii) the short term complications of Lletz (large loop excision of the transformation zone) at this clinic. Design. A retrospective analysis of data from the colposcopy clinic database of patients; who were referred according to national guidelines. Setting. Patients who are referred to Chris Hani Baragwanath hospital. Results. Normal histology was found in 1.3 of patients; and cervical intraepithelial neoplasia (CIN) 1 or human papillomavirus (HPV) in 8.4. The overall complication rate was 3. Conclusion. The high loss to follow-up and the low early complication rate together with an acceptable overtreatment rate make this a justifiable approach in our situation. HIVnegative women were more likely to be overtreated than HIVpositive patients (p=0.03)

Obstetric Anaesthesia : the Source of the Crisis

The Saving Mothers Reports have consistently shown that; out of all the provinces of South Africa; the Free State has one of the highest rates of maternal deaths arising from anaesthesia.The province's Department of Health requested the University of the Free State's Department of Anaesthesiology to investigate the problem. We examined possible factors; including training and experience of doctors administering anaesthesia; availability of suitable anaesthetic drugs and equipment; and use of regional anaesthesia. All the level 1 and 2 hospitals in which caesarean sections (CSs) were being performed were investigated. The foremost problems identified were lack of training andexperience in administering obstetric anaesthesia; and lack of senior anaesthetic assistance
