Introduction: COVID-19 impacted healthcare systems worldwide, and elective surgical activity was brought to a minimum. Although children were not primarily affected by the disease, pediatric urology was halted by clinical closedown and staff allocation. We aimed to document how these prioritizations affected waiting lists, and to investigate how European centers dealt with the challenge of these logistical and financial prioritizations.

Materials and Methods: This was a 1-year prospective study, starting March 2020. Participants were surveyed at 3-month intervals about waiting lists for several common procedures as well as OR capacity and funding. Further, centers retrospectively reported on surgical and outpatient activity rates during 2019–2021. Waiting list tendencies were evaluated in relation to study baseline.

Results: A marked decrease in surgical and outpatient activity was seen in the spring of 2020. Some included pediatric urology centers were able to increase their budget (15%) and staff working hours (20%) during part of the study period. Still, at the end of the study, the centers had increased the total number of patients on waiting lists with 11%, whereas the average days on waiting lists had accumulated with 73%, yielding a total of 6,102 accumulated waiting days in the study population. Centers with decreased resources had markedly negative effects on waiting lists.

Conclusions: Correlations between COVID-19 derived burdening of healthcare systems and the availability of pediatric urology greatly depends on the prioritizations made at individual centers. Ongoing monitoring of these correlations is warranted to safely avoid unnecessary negative impact on the pediatric population.

Introduction

Coronavirus disease 2019 (COVID-19) deeply impacted the activity of pediatric urology cases in Europe and has had consequences during an extended period of time. Early on in the pandemic, statements and guidelines from European and North American pediatric urological societies recommended only to perform surgery in cases of organ- or life-threatening disease during lockdown, and further suggested to reduce all outpatient clinic consultations during the first wave of the COVID-19 pandemic (13). New protocols have been established to adopt minimally invasive surgery to treat pediatric surgical and urological pathologies during this pandemic, aiming at preserving both patient's and surgeon's safety (4, 5). While these guidelines were structured to prioritize cases in relation to urgency, clinics were also facing the challenge of complying with and taking in to account the varying degrees of less urgent, however already heavily surceased, elective procedures (6).

This initiative was undertaken in order to launch a collaborative European multicenter study on the COVID-19 pandemic and how this has affected pediatric urology cases and patients related to the ERN eUROGEN work stream 1 disease areas. The primary aim of the study was to evaluate how closure of elective interventions affected the pediatric urology population by increased time and patients on the waiting list for surgical interventions. The secondary aim was to evaluate how different centers dealt with the problem of an increased caseload before and after re-opening.

By prospectively gathering data from European centers, we intended to provide an overview of the current impacts which could be used as a tool for information and political decision-making at a local, regional, or European level. Since the COVID-19 pandemic is far from over, and since new pandemics may very well arise, this paper is meant to help in the future planning for dealing with pandemics or other major crises affecting societies and health care.

Materials and Methods

This was a European multicenter study comprising 10 tertiary pediatric urological centers broadly representing most parts of western Europe (Table 1). Centers were recruited by asking representatives from all the health care providers that were part of the European reference network eUROGEN work stream 1 (rare congenital urogenital and rectal anomalies) or by direct contact with European centers fulfilling the European reference network inclusion criteria (7).

TABLE 1
www.frontiersin.org

Table 1. Participating centers with corresponding country codes and reference populations in million people.

To be included in the study, the participating center would have to be a tertiary referral center performing advanced pediatric urology cases, although not by definition exclusively. Centers should have access to pediatric intensive care units, a minimum of 1 million population base for referrals of specialized pediatric urology and/or pediatric surgery cases, and in an area where COVID-19 closedown required cancellations of all elective surgery (only running emergency and imperative cases). Chief of department in all centers approved retrieval of information regarding waiting lists to surgery and data collection, and surveys were compiled and answered by the co-author representing each center. All reported data from waiting lists was anonymized on a patient level.

The study design was a longitudinal, prospective study based on pediatric urology cases waiting lists in different European centers. Centers participated over a 13-months study period (March 2020 to April 2021). At five timepoints (March, June, October, January, and April, respectively), centers were asked to count the waiting lists within a range of predetermined elective, non-emergent and non-oncologic urological procedures (Table 2). To differentiate our results further, centers were asked to report on both the number of patients waiting and the accumulated days waiting for each procedure. Averaged cross-country European COVID-19 numbers were included as an intuitive reference to the broadscale implications of the pandemic. Data on nationwide new weekly COVID-19 admissions and completed vaccinations were gathered from the publications of the European Center for Disease Prevention and Control (8).

TABLE 2
www.frontiersin.org

Table 2. Total number of patients and mean days per person on waiting lists, for each procedure of interest and across all participating centers, presented in absolute numbers.

To investigate whether the obtained waiting list data corresponded to the actual number of surgical procedures and outpatient consultations performed, before and during the study period, all centers were requested to further retrospectively report administrative data on these activities from January 2019 throughout September 2021. To compare with pre-COVID-19 capacities, as well as normal seasonal variation, this data was presented per annum. Moreover, to compare with the corresponding outpatient activities, data on external referrals for pediatric surgical evaluation during the same period was obtained from two participating centers.

Synchronously, qualitative online surveys regarding financial, logistic, and organizational changes were obtained using Redcap® (questions asked can be found in Figure 6). The participants were surveyed at four timepoints during the study period (June, October, January, and April, respectively).

Statistics

Descriptive statistics were based on absolute numbers from reported waiting list at the five study timepoints. Given the explorative nature of our data, further advanced hypothesis testing models were not considered appropriate. Centers that were not able to provide complete waiting list data on the respective procedures for all timepoints were not included in the quantitative results.

Since data from large-volume centers might dominate the statistical tendencies in the general results, we assessed the proportional waiting list changes, to level out possible skewing from varying center sizes and operative volumes. The mean of the percentual waiting list changes from each center were assessed with reference to the study baseline (March 2020). Due to low sample-sizes and high variance in rare procedures, this was only deemed suitable for a limited number of high-volume procedures, defined in this study as >10 patients per center waiting on average at each timepoint (i.e., hypospadias, phimosis, non-descended testes, cystoscopy).

Numeric survey data is presented separately in percentages in stacked bar charts. Data and figures were analyzed using Microsoft® Office Excel 2016 and IBM® SPSS Statistics version 25.

Results

A total of 10 tertiary European centers of pediatric urology, representing a background population of 21.6 million people (individually ranging from 1.2 to 3.3 million), were included prospectively in the study. According to 2019 cross European demographics, this corresponds to a total pediatric reference population <15 years of 3.26 million (9). All participating centers experienced a complete initial COVID-19 related closedown of elective pediatric urology cases, which happened medio March 2020 (effectuated between March 3rd and 17th and ended between March 20th and September 1st, respectively).

Quantitative Data

Seven centers (70%) were able to provide complete waiting list data for all timepoints, corresponding to a reference population of 17.7 million inhabitants. Results from the total counting of waiting lists at the five study timepoints across all participating centers are first presented in absolute numbers (Figure 1, Table 2). An increase in mean days waiting was seen during spring 2020 and again during late fall. This corresponded to the fluctuations of the first and second wave of infections in Europe. The total number of patients waiting for surgery did not increase on a broadscale during the first wave of infections, however it did increase during the second wave.

Figure 1. Waiting list tendencies during the COVID-19 pandemic. Total number of patients and average days on waiting lists across all participating centers for all procedures of interests are presented in absolute numbers. Mean cross-European data on new COVID-19 admissions and completed vaccinations are shown in absolute numbers for intuitive comparison (note these should be read from secondary Y-axis).

Both the number of patients and the mean days waiting generally decreased during the summer of 2020, after the first wave of infections, whereas a corresponding decrease was not seen after the second wave. At the end of the study, the included pediatric urology centers had increased the overall number of patients on waiting lists with 11% (from 1,010 to 1,123 patients), whereas mean days on waiting list had accumulated with 73% (from 74 to 128 days) (Figure 1). Over the entire course of the study period, the total accumulation of waiting days consequently attenuated with 6,102 days within the study population.

Evaluation of the proportional changes in waiting lists for high-volume procedures generally revealed clear gradual increase in the average days spent on waiting lists at the end of the study period (increasing with 62% for cystoscopy, 45% for orchidopexy, 36% for hypospadias and 70% for foreskinplasty). The changes in waiting lists corresponded to the nationwide fluctuations in the COVID-19 pandemic, although with some possible delay between new waves of infections and increasing waiting lists (Figure 2, Supplementary Table 1). The number of patients waiting remained stable until finally increasing in some procedures during the second half of the study period (final increase of 5% for cystoscopy, 7% for orchidopexy, −9% for hypospadias and 35% for foreskinplasty). These changes corresponded to a delay in seeing patients at the outpatient clinic for planning new surgical interventions.

The mean proportional changes (in percentage) across all centers are presented with reference to study baseline (March 2020).

Seven centers (70%) were able to provide additional administrative data on performed surgical procedures and outpatient consultations. Tendencies confirmed decreased activities with a clear dip during the first pandemic wave, when compared to activity levels of 2019, corresponding to a stagnation in number of patients entering the waiting lists during the first part of the study (Figures 3, 4). When evaluating external referrals, a corresponding decrease in activity was also seen during spring 2020 (Figure 5).

Qualitative Data

All 10 centers provided full survey data from each of the four survey timepoints. Financial resources remained unreduced in ~80% of the centers during the study period but with uncertainties at the last survey. A tendency of extra funding was reported in 15% of centers during the second half of the study (Figure 6A). A tendency of lesser funding was reported in an equal number of centers (15%) and these centers were also more heavily burdened by the COVID-19 pandemics at a national level. Operating room (OR) capacity was reduced with at least 75% at 3-months after the closedown in 70% of centers, while 30% had been able to re-establish their capacity to 76–100% of normal. In approximately half of the centers a decrease in OR capacity clearly followed the first and second wave of infections in Europe (during the spring and fall of 2020, respectively) (Figure 6B). Three months after initial closedown (June 2020) 40% experienced a decrease in OR staff compared to normally, however during the remaining study period, an increasing number of centers were able to sustain or even increase the OR staff working hours to endure the increasing caseload (Figure 6C). Consequently, rather than lack of human or material resources, at the end of the study period, general ongoing COVID-19 situation was viewed as the main limiting factor for OR capacity throughout the study period in most centers (Figure 6D).

Figure 6. Compiled survey data from all centers. Each subfigure represents a question from the survey: (A) Have your financial resources changed after the Covid-19 close-down? (B) Have you now reached the same OR capacity as before close-down? (C) Have you been able to increase team-member working hours (i.e., surgeons, anesthesiologists, OR nurses and postop team), in order to decrease the waiting list? (D) What is the main limiting factor right now for full OR capacity? (E) Did you follow ESPU or national guidelines to deal with the waiting list during and after closedown?

In January 2021, 60% of centers reported a second closedown (effectuated between October 5th and December 2nd and lasting on average 2–3 months, although still ongoing in two centers at the end of the study period) with a corresponding decrease in OR capacity in almost 50% of centers. Management of waiting lists was done in accordance with various guidelines depending on each center, with ~20% of centers following ESPU guidelines and 40% following local hospital guidelines, and centers generally adhered to the same guidelines throughout the study period (Figure 6E).

Combined Quantitative and Qualitative Data

When evaluating the mean proportional changes for all high-volume procedures in relation to funding, a larger increase in number of patients waiting was seen in centers reporting on less funding in the final survey compared to centers reporting unreduced or additional funding. This tendency was not seen in relation to mean days waiting (Figure 7). Similar tendencies were seen when evaluating the proportional changes in relation to OR staff working hours; less ability to increase staff working hours at the end of the study was correlated with increased numbers of patients waiting, whereas this tendency was not seen in relation to mean number of days waiting (Figure 8).

Discussion

This European multicenter study is the first of its kind to report on prospectively gathered multicenter real-time data on the ongoing impacts of COVID-19 on elective surgeries in European pediatric urological populations. Our study presents waiting list outcomes for a variety of 17 urological procedures from tertiary European referral centers for pediatric urology within the first year of the COVID-19 pandemic, covering a population of ~22 million persons.

Since the outbreak of the COVID-19 pandemic, pediatric surgical activities has evidently been reduced worldwide (1013) and although the quality of the surgical treatment does not seem to have diminished during the pandemic (14), increased time to surgery has been documented in various urgent pediatric cases, such as acute appendicitis (15, 16) and testicular torsion (17, 18). Further, the pandemic has impacted on the training of new pediatric surgeons (19) and presumably also on non-COVID-19 related pediatric research (20). In non-urgent elective cases however, the effect of the current administrative prioritizations, halting surgical activities, has not yet been investigated prospectively on a multicenter level.

In our material we found that during the first half of the study period, the number of patients on waiting lists for most surgeries remained stable and did not increase until the second half. This is explained by a reduced intake via outpatient clinics, consequently halting new OR bookings during the initial closedown.

Later during the study period, the number of patients on waiting lists and accumulated waiting time increased for most procedures, although we did encounter tendencies that some procedures were prioritized. These procedures, although many of them performed on rare diseases with consequently small sample-sizes, often represented cases with life- or organ-threatening conditions (pyeloplasty, bladder exstrophy, heminephrectomy). Still, for now, any conclusions regarding low-volume procedures can only be speculative. However, when evaluating the proportional waiting list changes at the end of the study period, we did find a clear increase in the accumulated time waiting for all four high-volume surgeries (hypospadias, cystoscopy, foreskinplasty and orchidopexy), in addition to an increase in number of patients waiting.

Attenuated waiting lists generally reflected the first and second wave of European COVID-19 infections, and indications of compensatory activities to decrease waiting lists were seen after the first wave, during summer 2020. However, similar tendencies were not found after the second wave, where waiting list continued to increase, which may indicate an exhaustion of the center capacities, limiting the ability to compensate for attenuated waiting lists with more elective operating room time. This exposes a limit of robustness in the health care systems with regards to compensatory means that might have reached an upper limit in many centers at that time. Although the data material obtained in this study was largely explorative, allowing only for descriptive statistical analysis, the gradually attenuating waiting lists during the first year of COVID-19 were convincing, and in general corresponded to similar reports from adult surgery waiting lists in the same period (2124).

According to the survey data, OR capacity decreased in more than half of the participating centers, however, most centers were able to maintain or increase their financial budget (60–80%), as well as OR staffing (70%), during the second half of the study period. Still, at the end of the study, half of the centers still reported an OR capacity below 75%, due to an ongoing COVID-19 situation. Guideline adherence for prioritizing surgical cases, varied greatly within the study group, however, remained unchanged throughout the study period. Our findings related to high-volume cases support that prioritization was quite similar between centers, although different guidelines were used.

Not all centers reported on a 2nd closedown (60%), but waiting lists were markedly increased at the second wave, much more than after the first. This may be due to closing of elective surgeries but still performing the outpatient clinics. One of the most critical measures of the quality of a country's health care system is how long patients must wait to access medical care. Our study demonstrated a waiting time of ~2.5 months for a surgical intervention in general anesthesia before the pandemic, to more than 4 months for the average pediatric patient after 1 year of the pandemic.

Patients perspectives have been reported to play an important role in the rate of hospital contacts during the pandemic, and although this was not possible for us to evaluate in the current study, we do suspect that fear of seeking healthcare, as seen in other studies on emergency conditions, has also influenced elective waiting lists (12, 15, 17, 18, 25, 26). Several new advances have been implemented in many clinics during the pandemic, to meet with the emerging challenges. Telemedicine for one has proven to be a valuable tool in the reduction of physical outpatient activity by replacing actual meetings with either telephone, video or online consultations. Surveys have demonstrated acceptable user satisfaction rates despite short-notice introduction of the new technique (27, 28), although possibly susceptible to social and economic disparities (29). New telemedical guidelines have been proposed and might very well find a more permanent place in future pediatric practices (30).

European centers will ongoingly need to plan more elective surgeries to address the currently increased caseload. This study should be understood in the context of an ongoing worldwide health crisis from which the full impact on healthcare systems are yet to be seen, warranting further monitoring and analysis. In respect to waiting time for interventions in patients which we know have morbidity in delay for treatment, we do not have tools for estimating loss of quality of life, and neither cost related to postponing surgeries (i.e., medications, monitoring, outpatient visits, parents needing to stay home from work to take care of their child, children not attending school). It is feasible, however, that the impact of patients and parents staying home longer, while waiting for surgery, will have social, educational and economic consequences for the families, as well as possible progression of the underlying medical conditions (31).

At present, some European countries are still facing a heavy burden on healthcare due to the COVID-19 situation. In addition, we do not know how the European health care systems will react during a post-COVID-19 period, in the sense that health care workers have been exhausted by the emergency of high workload and long working hours. In addition, patients that are subjected to post-COVID-19 symptoms may cause further challenges to the healthcare systems to provide and prioritize care of patients (32, 33). By these means, pediatric urology waiting lists may further increase before it can go back to the same level as before COVID-19.

The prospective study design ensured that data was gathered consistently throughout the study period. By including a variety of centers throughout Europe, we believe that the waiting list tendencies found among the participating centers can indeed be translated to other countries and other regions or continents with similar socio-economic health resources. If looking at the whole population of the European Union (447 million), and if our data provided could represent the whole union, then an extrapolation with a 30-fold increment would represent the whole union; waiting lists could be expected to increase with 183 060 accumulated waiting days due to the pandemic (3 390 new pediatric patients waiting and an increased waiting time of 54 days).

In conclusion, closure of elective interventions affected the pediatric urology population by an increased number of patients waiting for surgery and an increase in time on waiting lists (70% longer) for surgical interventions. Some centers dealt with the problem by increasing their operating resources off-hours, however, it is still not known how many more patients will suffer from delays before it turns back to normal again. Political decision-making and unified forces will be needed to restore a reliable health care system that attends the pediatric population in a timely manner.
