Compliance to the South African ventral hernia guidelines: inaugural results from the HIG(SA) registry.

BACKGROUND: The Hernia Interest Group (HIG) of South Africa (SA), following the publication of their inguinal and ventral hernia guidelines (in 2015 and 2016 respectively), developed a hernia registry, the HIG(SA) hernia registry. METHODS: A retrospective analysis of the prospectively maintained HIG(SA) hernia registry from 1 February 2019 to 29 February 2020. Compliance to six recommendations made in the HIG(SA) ventral hernia guidelines were assessed in both the public and private healthcare systems. RESULTS: Three hundred and fifty-three ventral hernia repair cases were included in the study. Fifty-four per cent were private and 46% were public sector cases. Laparoscopic repair for patients with a BMI > 35 kg/m2 occurred in 38% of eligible cases and a minimum 5 cm of mesh overlap was achieved in 50% of cases. Overall, 80% of elective cases occurred in non-smokers; 97% of the intraperitoneal on-lay mesh (IPOM) repairs used composite mesh; 96% of ventral hernias with defects of larger than 2 cm and 95% of incisional hernias were repaired with mesh. Non-smokers undergoing repair numbered 72% in public and 85% in private practice, p = 0.01. CONCLUSION: Ventral hernia repair practices in SA facilities overall had good compliance to four out of the six HIG(SA) ventral hernia guidelines highlighted for the purposes of this study. The two guidelines that had poor compliance overall were 'laparoscopic repair for patients with a BMI of > 35 kg/m2' and 'ensuring a mesh overlap of 5 cm'. The public sector had higher rates of current smokers undergoing elective ventral hernia repair.

Estimating the surgical backlog from the COVID-19 lockdown in South Africa: A retrospective analysis of six government hospitals.

BACKGROUND: The COVID-19 pandemic reached South Africa (SA) in March 2020. A national lockdown began on 27 March 2020, and health facilities reduced non-essential activity, including many surgical services. PRIMARY OBJECTIVE: to estimate the COVID-19 surgical backlog in Western Cape Province, SA, by comparing 2019 and 2020 general surgery operative volume and proportion at six district and regional hospitals. SECONDARY OBJECTIVE: to compare the operative volume of appendicectomy, laparoscopic cholecystectomy, cancer and trauma between the 2 years. METHODS: This was a retrospective study of general surgery operations from six SA government hospitals in the Western Cape. Data were obtained from electronic operative databases or operative theatre logbooks from 1 April to 31 July 2019 and 1 April to 31 July 2020. RESULTS: Total general surgery operations decreased by 44% between 2019 (n=3 247) and 2020 (n=1 810) (p<0.001). Elective operations decreased by 74% (n=1 379 v. n=362; p<0.001), and one common elective procedure, laparoscopic cholecystectomy, decreased by 68% (p<0.001). Emergency operations decreased by 22% (n=1 868 v. n=1 448; p<0.001) and trauma operations by 42% (n=325 v. n=190; p<0.001). However, non-trauma emergency operations such as appendicectomy and cancer did not decrease. The surgical backlog for elective operations after 4 months from these six hospitals is 1 017 cases, which will take between 4 and 14 months to address if each hospital can do one additional operation per weekday. CONCLUSIONS: The COVID-19 pandemic has created large backlogs of elective operations that will need to be addressed urgently. Clear and structured guidelines need to be developed in order to streamline the reintroduction of full surgical healthcare services as SA slowly recovers from this unprecedented pandemic.

Building a national hernia registry in South Africa: initial ventral hernia repair results from a diverse healthcare sector.

PURPOSE: The purpose of this paper was to introduce a new registry in a developing country by describing the demographics, management and 30-day outcomes of patients undergoing ventral hernia repair in the public and private healthcare sectors of South Africa. METHODS: This study was a retrospective review of a prospectively maintained hernia registry from the 1st of February 2019 to 29th of February 2020. RESULTS: 353 ventral hernia repair cases were recorded of which 47% were incisional hernias and the remainder were primary hernias. The median age was 54 years with even distribution of males and females. Half of the patients were obese with a median BMI of 31 kg/m2. The private sector performed 190 cases (54%) and the public sector 163 cases (46%). The public sector had more current smokers undergoing elective repairs, 28% vs 15%, p = 0.01 and performed more emergency repair cases, 21% vs 8%, p < 0.01. The majority (89%) of hernias were repaired with mesh and one-third were repaired laparoscopically. 30 day follow up was obtained in 30% of cases, the private sector had better follow up rates (42% vs 14%). CONCLUSION: Participation in the HIG (SA) registry was low with poor follow up over the first year. Ongoing prospective data capture on the HIG (SA) hernia registry will continue to provide further insights into hernia repair practices in South Africa.

Changes in surgical practice in 85 South African hospitals during COVID-19 hard lockdown.

BACKGROUND: In preparation for the COVID-19 pandemic, South Africa (SA) began a national lockdown on 27 March 2020, and many hospitals implemented measures to prepare for a potential COVID-19 surge. OBJECTIVES: To report changes in SA hospital surgical practices in response to COVID-19 preparedness. METHODS: In this cross-sectional study, surgeons working in SA hospitals were recruited through surgical professional associations via an online survey. The main outcome measures were changes in hospital practice around surgical decision-making, operating theatres, surgical services and surgical trainees, and the potential long-term effect of these changes. RESULTS: A total of 133 surgeons from 85 hospitals representing public and private hospitals nationwide responded. In 59 hospitals (69.4%), surgeons were involved in the decision to de-escalate surgical care. Access was cancelled or reduced for non-cancer elective (n=84; 99.0%), cancer (n=24; 28.1%) and emergency operations (n=46; 54.1%), and 26 hospitals (30.6%) repurposed at least one operating room as a ventilated critical care bed. Routine postoperative visits were cancelled in 33 hospitals (36.5%) and conducted by telephone or video in 15 (16.6%), 74 hospitals (87.1%) cancelled or reduced new outpatient visits, 64 (75.3%) reallocated some surgical inpatient beds to COVID-19 cases, and 29 (34.1%) deployed some surgical staff (including trainees) to other hospital services such as COVID-19 testing, medical/COVID-19 wards, the emergency department and the intensive care unit. CONCLUSIONS: Hospital surgical de-escalation in response to COVID-19 has greatly reduced access to surgical care in SA, which could result in a backlog of surgical needs and an excess of morbidity and mortality.

The developing world of pre-operative optimisation: a systematic review of Cochrane reviews.

Pre-operative optimisation is a heterogenous group of interventions aimed at improving peri-operative outcomes. To understand the evidence for pre-operative optimisation in the developing world, we systematically reviewed Cochrane reviews on the topic according to the Human Developmental Index (HDI) of the country where patient recruitment occurred. We used summary statistics and cartograms to describe the HDI, year of publication, timing of pre-operative intervention and risk of bias associated with each included trial. We assessed the impact of multinational trials on the risk of bias introduced by countries of differing HDI. Four-hundred and nine trials representing 51 countries and 89,389 randomly allocated participants were summarised in this review. Four-hundred and nineteen out of 451 (93%) trial populations (i.e. a group of study participants from one country) were from high and very high HDI countries. The median (IQR [range]) HDI of countries were 0.862 (0.806-0.892 [0.445-0.949]). Three of the 409 included trials were multinational, representing 32 countries and 37,736 out of 89,389 (42.2%) included participants. Africa was the least represented continent, with only 4 included trials and 566 participants, of which 62.3% were from one multinational trial. The overall risk of bias was high or unclear in 381 out of 409 (93%) trials. Inclusion of multinational trials decreased the proportion of trial populations introducing high or unclear risk of bias by 9.4% (95%CI 5.1-13.7; p < 0.0001). Half of the world's population live in low- and middle-HDI countries. This population is poorly represented in systematically reviewed evidence on pre-operative optimisation. Multinational trials increase the knowledge contribution from low- and middle-HDI countries and decrease risk of bias in systematic reviews.
