moreBackground In an attempt to discern lessons to improve future pandemic responses, this study measured the effects of the COVID-19 pandemic on essential public health services (EPHSs) related to primary health care (PHC) and outpatient department (OPD) utilisation, antiretroviral treatment (ART) commencement, drug-susceptible tuberculosis (DS-TB) con rmation and treatment commencement, and Bacillus Calmette-Guérin (BCG) coverage, in the Free State province of South Africa during January 2019 to March 2021. Methods A pre-post study design comparing EPHS performance between 2019 and 2020/21 was employed. Routinely collected data were analysed. An interrupted time series analysis was used to measure changes in service use and outcomes from January 2019 to March 2021. Median changes were compared using Wilcoxon sign ranked tests. A 5% statistical signi cance level was considered Results Over the study period, the median values for the annual number of PHC visits was 1.8, 55.3% for unreferred OPD visits, 69.4% for ART commencement, 95.1% and 18.7% for DS-TB con rmation and treatment commencement respectively, and 93.7% for BCG coverage. While BCG coverage increased by 5.85% (p=0.0101), declines were observed in PHC utilisation (10.53%; p=0.0010), unreferred OPD visits (12.05%; p=0.0006), ART commencement (9.53%; p=0.0174), and DS-TB con rmation (5.24%; p≥0.050) and treatment commencement (3.80%; p≥0.050). Given the importance of PHC in addressing a new pandemic, along with the existing HIV and TB epidemics-as well as the entire quadruple burden of disease-in South Africa, the nding that the PHC utilisation rate statistically signi cantly decreased in the Free State post-COVID-19 commencement is particularly concerning. Conclusions The lessons learned from this retrospective review attest to a measure of resilience in EPHS delivery in the Free State in as far as a signi cant hike in BCG vaccination over the study period, 2019-2020/21 was observed. As evidenced by a declines in PHC service utilisation, the decreased numbers of new patients commencing ART and lower con rmed DS-TB case and DS-TB treatment commencement rates, we also learned that EPHS delivery in the province was fragile. Background The COVID-19 virus infected more than 600 million and killed more than 6.5 million people [1]. With the end of the pandemic in sight [2-4], it is prudent to assess its effects on health care systems to identify challenges in order to strike a balance between managing emergencies and maintaining essential public health services (EPHSs) in the future [5-11]. After declaring the COVID-19 outbreak a global pandemic on 11 March 2020, on 1 June 2020 the World Health Organization (WHO) provided operational guidance to avert indirect morbidity and mortality and prevent acute exacerbations of chronic conditions when services are disrupted. Although the WHO [11 p. 6] emphasised certain high-priority health service areas-such as essential prevention and treatment services for communicable diseases, including immunisations-it stressed that countries should identify context-relevant EPHSs to be prioritised for continuation during the acute phase of the COVID-19 pandemic. South Africa embarked on a rapid COVID-19 response, characterised by the temporary suspension of research, diversion of key HIV and TB control resources, and regulation of patient access to health care facilities (12]. Early in the COVID-19 pandemic, an assessment of its impact on access to publicsector health care in South Africa indicated a sharp reduction in primary health care (PHC) utilisation [13]. Based on analysis of routine health care utilisation data from the District Health Information System (DHIS), this study reported that the pandemic had a considerable in uence on healthcare utilisation during April and May 2020 when strict lockdown regulations were in effect. There was dramatic impact on total and under 5 utilisation of PHC, as well as HIV testing. However, early access to antenatal care was only somewhat affected and recovered quite quickly after this period. Based on data routinely collected via the DHIS in 2019 and 2020, Pillay et al. (2021) analysed the impact of the COVID-19 pandemic in South Africa and reported that the severely restrictive lockdowns to reduce transmission and limit the number of patients requiring hospitalisation had mixed consequences for routine health services [14]. The services most seriously affected were early child care, access to contraceptives, and testing for HIV and TB. While a wide variation of measurable effects on EPHSs were observed, this varied by type of service, province and district. The full extent of the impact of the COVID-19 on the EPHS spectrum in South Africa is not yet clear. This study aimed to address the need for evidence on the impact of COVID-19 on EPHSs in the Free State province. In order to learn lessons to mitigate the impact of future pandemics on EPHSs, the objectives were to establish the effects of COVID-19 on EPHSs related to 1) PHC and 2) outpatient department (OPD) utilisation, 3) the antiretroviral treatment (ART) commencement rate, 4) the drug-susceptible tuberculosis (DS-TB) con rmed rate, 5) the DS-TB treatment commencement rate, and 6) Bacillus Calmette-Guérin (BCG) coverage during January 2019 to March 2021. The DS-TB con rmed and treatment commencement and BCG coverage rates respectively relate to the overall global agenda to improve TB diagnosis, care, and prevention [15, 16]. The ART commencement rate relates to one component (care or treatment) of the global agenda to improve HIV diagnosis, care, and treatment [17]. Methods Setting One of the country's nine provinces, the Free State is located in inland South Africa. The province had a population of 2 928 903 million in 2020 [18] and accommodated about 5% of the public health sector dependant population in the country, of whom more than 80% are African [19]. The province is confronted with serious public health systems challenges, including fragmentation of service delivery [20, 21]. The majority of the citizens are historically
