COVID-19 Pandemic Was Associated with Lower Activity but Not Higher Perioperative Mortality in a Large Eastern European Center.

BACKGROUND Surges of critically ill patients can overwhelm hospitals during pandemic waves and disrupt essential surgical activity. This study aimed to determine whether hospital mortality increased during the COVID-19 pandemic and during pandemic waves. MATERIAL AND METHODS This was a retrospective analysis of a prospective, observational, epidemiological database. All patients who underwent surgery from January 1 to December 31, 2020, were included in the analysis. The setting was a large Eastern European Surgical Center referral center of liver transplant and liver surgery, a major center of abdominal surgery. RESULTS A total of 1078 patients were analyzed, and this number corresponded to a reduction of surgical activity by 30% during the year 2020 compared with 2019. Despite an increase in surgery complexity during the pandemic, perioperative mortality was not different, and this was maintained during the pandemic wave. The pandemic (OR 1.45 [0.65-3.22], P=0.365) and the wave period (OR 0.897 [0.4-2], P=0.79) were not associated with hospital mortality in univariate analysis. In the multivariate model analysis, only the American Society of Anesthesiology (ASA) score (OR 5.815 [2.9-11.67], P<0.0001), emergency surgery (OR 5.066 [2.24-11.48], P<0.0001), and need for surgical reintervention (OR 5.195 [1.78-15.16], P=0.003) were associated with hospital mortality. CONCLUSIONS Despite considerable challenges, in this large retrospective cohort, perioperative mortality was similar to that of pre-pandemic practice. Efforts should be made to optimize personnel issues, while maintaining COVID-19-free surgical pathways, to adequately address patients' surgical needs during the following waves of the pandemic.

Background

Usual surgical activity was disrupted in the context of the new coronavirus (COVID-19) pandemic [1], particularly during the sudden surges in hospitalized patients associated with pandemic waves. These surges were expected to have a significant impact on adult elective surgeries in many countries, thus increasing perioperative mortality and the complication rate [2]. Each national health authority organized and made decisions according to local specificities, considering the COVID-19 pandemic evolution, healthcare characteristics, and other challenges [3-5]. Different recommendations concerning the postponing and cancelling of elective surgeries were proposed.

At a national level in Romania, owing to anticipated limitations in surge-response capacity, decisions were initially made to limit the number of non-urgent surgical interventions to free Intensive Care Unit (ICU) beds for patients with COVID-19 in need of ventilatory support or other specific therapies [6]. Later, hospitals were required to keep a dedicated ward and ICU beds for patients with COVID-19 as a back-up, while entire hospitals (mainly, but not limited to, those specializing in infectious diseases and pulmonology) were converted to COVID-19 facilities.

The impact of the pandemic on patient chronic pathologies and delayed surgeries has still not been very well evaluated, especially in the context of heterogenous measures and diversity of local conditions.

From the anesthesiologists’ perspective, the Romanian healthcare system has a history of chronic personnel deficits [7]; it was confronted with several challenges during the first year of the COVID-19 pandemic. The anesthesiologists are also intensive care medicine physicians and are responsible for ICU management and care, like those in various countries worldwide. Thus, the surges of critically ill patients in the successive waves of the pandemic posed challenges for staffing the operating rooms, particularly for non-urgent surgery, which were not fully addressed by emerging guidelines based on accumulating experience in other countries [8]. Medical staff volunteered or were temporarily transferred to other highly understaffed provincial hospitals due to new legislation allowing for relocation of physicians and nurses in areas under severe pressure caused by case overload [9]. Local personnel SARS-CoV-2 outbreaks required home-isolation or even hospitalization of staff members, creating further management difficulties [10]. Also, infrastructure particularities in the local ICUs caused another struggle, namely making patient isolation due to non-SARS-CoV-2 infections very difficult in a local environment with a high prevalence of antimicrobial resistance [11]. Dedicated personnel were hard to summon, which could have sometimes led to suboptimal bed use. This had an impact on surgical activity and, despite workload increase, owing to medical and administrative reasons, the chronic lack of medical staff was accentuated.

The main objective of this study was to evaluate the impact of the pandemic on perioperative mortality. The secondary objectives were (i) to evaluate the impact of wave periods on perioperative mortality; and (ii) to describe the patient profiles during the first pandemic year.

We hypothesized that diminished availability of medical personnel, restrictive surgical planning, and a lower number of available surgical ICU beds would be reflected in a higher incidence of perioperative mortality and surgical complications during the pandemic.

Material and Methods

Design

The study was a retrospective analysis of a prospective, observational, epidemiological database and was conducted in a single tertiary, university-affiliated national center, the main national center of liver transplant and liver surgery and a major center for abdominal surgery.

COVID-19 Pandemic in Romania

The timeline of the COVID-19 pandemic in Romania is illustrated in Figure 1. The pandemic was declared by the governmental authorities on March 16, 2020, when a state of emergency was issued with consequent restrictions, which had an impact on hospital activity [12]. This date was used to divide patients in our study into 2 groups by period: pandemic and non-pandemic. Furthermore, a surge in new cases with concomitant impact on ICU bed availability was registered from October 2020 until the end of 2020 (Figure 1). The patients undergoing surgery between October 1 and December 31, 2020, were treated in the context of the SARS-CoV-2 wave in data analysis. A comprehensive history of the epidemiology and legal framework of the pandemic in Romania is provided in Supplementary Table 1.

Patients and Data Collection

All patients who underwent surgery from January 1, 2020, to December 31, 2020, in our department were included. The preoperative demographical characteristics (age, sex, American Society of Anesthesiology [ASA] score) and the intraoperative data (type and length of surgery, emergency status, cancer surgery, intraoperative packed red blood cell [PRBC] transfusion) for each patient were entered in an electronic database by the anesthetist at the end of surgery. Hospital mortality was recorded using electronic records.

Statistical Analysis

Data were collected in a Microsoft Excel database and analyzed using SPSS (IBM SPSS Statistics for Windows, version 21.0; IBM Corp, Armonk, NY, USA). A 2-sided P<0.05 was considered, a priori, statistically significant. Descriptive statistics were expressed as mean±standard deviation or as median with interquartile range (IQR; 25–75%), as appropriate. Normal distribution for continuous variables was evaluated by histograms and by the Kolmogorov-Smirnoff test. The t test or Mann-Whitney test were used, as appropriate, for comparisons of continuous variables. The chi-squared test was used to compare categorical variables.

We firstly determined the variables associated with 1-year mortality through univariate logistic regression analysis. Secondly, the statistically significant variables in univariate analysis were introduced in a multivariate logistic regression model to identify independent predictors of 1-year mortality. The rule of thumb of 5 to 10 events per variable in the multivariate logistic model was applied.

Management of Missing Data

There were no missing data in our final database. Therefore, no missing data strategy was required before the statistical analysis.

Clinical Pathway of Patients

As previously proposed by experts [13], all patients were screened for SARS-CoV-2 prior to elective surgery and if they were positive, their surgeries were either postponed, if possible, or transferred to another center dedicated to managing COVID-19 in surgical patients. There was, however, a small number of patients (5 of 1078) that underwent surgery as emergencies having COVID-19; therefore, no general considerations can be made regarding increased mortality in COVID-19 patients as mentioned by other authors [14].

Results

There were 1078 surgical patients in our department in 2020. The monthly distribution of surgeries is shown in Figure 2. When compared to the previous year (2019), the number of surgical patients corresponded to a reduction of 30% in surgical activity. The cohort demographic and surgical characteristics are shown in Table 1. The mean patient age was 59±14 years and 542 (50.28%) patients were female; 655 (60.76%) patients underwent a major surgical procedure; 663 (61.45%) interventions were performed in an oncological context; 216 (20.04%) were emergency surgeries; and 693 (64.3%) had an ASA score ≥III. The overall perioperative mortality was 3.25% (35 patients). The monthly variation of recorded mortality is shown in Supplementary Figure 1.

Patients’ characteristics are shown by the extra-pandemic, pandemic, and wave periods in Table 1. A total of 757 (70.2%) patients had surgery during the pandemic, and 267 (24.76%) patients underwent surgery during the COVID-19 wave. The comparative hospital mortality during the pandemic vs the extra-pandemic period was 3.57% vs 2.49% (P=0.363), respectively. Perioperative mortality did not increase during the wave (3.88% vs 3%, P=0.532). The patient profiles seemed to be slightly different during the pandemic, with a higher proportion of major (defined as surgery exceeding 90 min) and longer surgery: 174 (54.20%) vs 481 (63.54%) patients and 130 (80–195 min) vs 150 (90–217) min, respectively. Patients pre-pandemic and during the pandemic were similar with respect to age (monthly variation is shown in Supplementary Figure 2), ASA category, proportion of emergency surgery (proportion of the emergency interventions recorded monthly are shown in Supplementary Figure 3), and need for reintervention (Supplementary Figure 4), but there were differences in ASA category between wave-period and outside-of-wave patients: there were proportionally more patients with ASA I and II during the wave: 17 (6.37%) vs 17 (3.47%), and 107 (40.07%) vs 140 (28.57%), respectively, and fewer ASA III and IV patients: 134 (50.19%) vs 274 (55.92%), and 59 (12.04%) vs 9 (3.37%), respectively (P<0.0001).

The univariate and multivariate logistic regression analyses results are shown in Table 2. In univariate analysis, major surgery, emergency intervention, reintervention, and ASA score were associated with hospital mortality. The pandemic (OR 1.45 [0.65–3.22], P=0.365) and the wave period (OR 0.897 [0.4–2], P=0.79) were not associated with hospital mortality in univariate analysis. In the multivariate model analysis, only ASA score (OR 5.815 [2.9–11.67], P<0.0001), emergency surgery (OR 5.066 [2.24–11.48], P<0.0001), and need for surgical reintervention (OR 5.195 [1.78–15.16], P=0.003) were associated with hospital mortality. The statistical significance was unchanged in sensitivity analysis, forcing the pandemic and the wave context in a multivariate model.

Discussion

In our cohort, we did not find an increased perioperative mortality during the COVID-19 pandemic, despite an increase in surgery complexity, as shown by the higher proportion of major surgery (defined as surgery longer than 90 min), as well as the longer median duration of the interventions. These results are reassuring, considering the huge pressure on ICU beds and medical personnel during the pandemic.

As expected, the elective surgery activity diminished [2]. However, the study design could not directly evaluate the mortality of delayed, rescheduled, or cancelled surgical interventions, nor medium or long-term postoperative mortality.

The decline in our surgical activity was more important following the issue of the emergency state (Figure 2). This allowed for reorganization of the activity and better distribution of local healthcare resources and adoption of pandemic precautions as generally stated.

There are some explanations for our findings that disprove the research hypothesis. Firstly, the reduction in surgical activity allowed for a better logistical and resource allocation. This was possible because our tertiary center is not involved in the main local and regional emergency pathway but provides highly specialized expertise when requested [15]. Secondly, the local medical personnel are already accustomed to difficult and continuously changing logistic conditions [7].

More major surgeries were performed during the pandemic months, which is explainable as these cases were prioritized by the restrictive surgical planning, and their proportion increased. Minor surgeries were more likely to be postponed. Also, it is possible that other centers reoriented these patients due to the already mentioned logistical issues, which led to some general hospitals becoming dedicated COVID-19 enters and closing elective surgical activity altogether [6].

The preponderance of patients with a better general condition during the wave compared with those outside the wave, as indicated by the ASA category differences, suggested there could have been a selection bias during the wave toward healthier patients with fewer comorbidities, which could maximally benefit from surgery. This was not found, however, when comparing pre-pandemic to pandemic patient characteristics.

The main outcomes did not seem to change with the wave period. This finding might be explained by the fact that it was anticipated, and the operating schedule was even more reduced. The ICU had not been overwhelmed at any time.

Perioperative bleeding was statistically different between the pre-pandemic and pandemic cohorts: 5 (1.56%) vs 9 (1.19%) patients (P<0.001), but the clinical significance was minimal, given the low incidence. Also, there was no observable impact of the wave period on bleeding. Intraoperative PRBC transfusion remained low and did not differ either between pre-pandemic and pandemic levels or in regards to the wave period, suggesting a good adherence to previously issued patient blood management recommendations, for which our institution was a pilot center [16].

The perioperative mortality in our cohort was higher than that reported in other multicenter international cohorts (3.5% vs 1.5%) [17]. However, our cohort was similar to the usual activity, showing more severe patients (higher ASA score III vs I–II) and an older population, which was not different from that of pre-pandemic months. A second explanation is that we did consider emergency surgeries, not only elective patients, as reported in this international cohort.

There has been evidence during the pandemic that providing COVID-19-free surgical pathways is beneficial for patients in terms of mortality, respiratory complications, and SARS-CoV-2 infections [18]. Given the very low number of operated COVID-19 patients, the strict adherence to preoperative screening, as well as the protocol for transfer to dedicated COVID-19 centers, we believe our results confirm this hypothesis.

However, there were considerably fewer patients who underwent surgery during the pandemic year, which also includes 2.5 months previous to the decree of the emergency state, as compared with the previous year. The effect of postponing or cancelling these surgeries has not been addressed by our study and remains a potential cause of excess mortality at a regional and national level [19].

The strength of this study is that it shows data of epidemiological and public health interest from a large Eastern European surgical center during the COVID-19 pandemic with a clear and simple methodological design. To the best of our knowledge, this is the largest Eastern European study addressing this issue.

Study Limitations

The first limitation of this study is its single-center and observational design. However, we already pointed out above that our center has a specific role in the local national healthcare system, with very specialized surgical activity.

Another limitation is the small number of variables considered in the data analysis. Other confounding factors could have had an impact on surgical mortality. Unfortunately, the database was not initially created with the purpose of exhaustively analyzing perioperative mortality. However, this limitation might generate an indiscriminative bias, affecting both pandemic and non-pandemic patients in data analysis, thus keeping the findings relevant in the current context. Also, the database was robust, without any missing data.

Ideally, the patients needed to be compared with those of the previous years, considering the same months of the year. This is another limitation of this study. However, we assumed that surgical activity is not mainly season- or month-dependent.

Conclusions

Despite considerable challenges regarding logistics and personnel, perioperative mortality was similar to pre-pandemic practices in our cohort, that of a tertiary care, academic hospital, the main center of liver transplant and a major center for abdominal surgery in an Eastern European country. This seems reassuring at a local level and should be regarded as a potential model for clinical practice. Special consideration should be given to pandemic waves, when surges of patients can lead to selection of less ill patients, with difficult to estimate consequences on mortality on a national level.

Efforts should be made to optimize personnel issues, while maintaining COVID-19-free surgical pathways to adequately address surgical needs during following waves of the pandemic.
