Effect of national COVID-19 lockdown on the incidence of muscle, tendon and ligament injuries and related surgical procedures in the working-aged Finnish population.

INTRODUCTION: The effect of lockdown on the incidence of fractures and severe injuries has been widely studied, whereas studies regarding muscle, tendon, and ligament injuries have not received as much attention. The aim of the study was to investigate the effect of the lockdown and later regional regulations due to the COVID pandemic on the incidence of muscle, tendon, and ligament injuries and related surgical procedures. MATERIALS AND METHODS: This study focuses on the working-age population in the catchment areas of three major Finnish hospitals. Patients were divided into three age groups 18-34, 35-50 and 51-65 years of age. Suitable injuries were retrieved from the data using appropriate ICD-10 codes and procedure codes. The monthly incidence rate ratio (IRR), with 95% confidence intervals (CI), were compared between the year 2020 and the reference years 2017-2019. RESULTS: Upper and lower extremity injury ED visits decreased by 15.7 and 8.2%. For upper extremity injuries, a decrease in incidence was observed for all three age groups in March (IRR 0.52, CI 0.33-0.80), (IRR 0.53, CI 0.31-0.91), (IRR 0.60, CI 0.38-0.95), respectively. An increase in 18-34 years of age group was detected in June (IRR 1.49, CI 1.05-2.13). Lower extremity injuries decreased in 18-34 years of age group in March (IRR 0.62, CI 0.43-0.90) and April (IRR 0.60, CI 0.42-0.87). A decrease on the incidence of surgeries was observed in April for the 35-50 (IRR 0.53, CI 0.29-0.97) and 51-65 years of age groups (IRR 0.58, CI 0.34-0.98). CONCLUSIONS: The nationwide lockdown in spring 2020 led to a notable decrease in the incidence of emergency department visits and the surgical treatment of muscle, tendon, and ligament injuries in Finland.

Trends in Emergency Department Visits and Surgeries due to Traumatic Brain Injury During the COVID-19 Pandemic in Finland

We aim to evaluate the changes in the incidence of TBI, trauma craniotomies, and craniectomies during the COVID-19 pandemic in Finland. This retrospective register study was conducted at three Finnish hospitals. We retrieved the numbers of emergency department (ED) visits, inpatient admissions, and trauma craniotomies and craniectomies due to TBI in the adult population from 2017 to 2020.We calculated the incidences per 100 000 inhabitants and compared the year 2020 to the reference years (2017–2019) by incidence rate ratios (IRR) with 95% confidence intervals. The incidence of TBI-related ED visits during the study period compared to the reference years started to decrease in March 2020 (IRR 0.86, CI: 0.73–1.02), and the lowest incidence was seen in April 2020 (IRR 0.83, CI: 0.68–1.01). The incidence of ED visits showed a second decrease in December (IRR 0.80, CI: 0.67–0.96). The incidence of concussion decreased during the national lockdown in March (IRR 0.80, CI 0.66–0.97). The incidence of ED visits due to TBI decreased after the declaration of national lockdown in spring 2020 and showed a second decrease during regional restrictions in December. In addition, the incidence of neurosurgically treated TBI decreased during restaurant restrictions in the spring.

Primary care visits due to mental health problems and use of psychotropic medication during the COVID-19 pandemic in Finnish adolescents and young adults.

BACKGROUND: Social restrictions due to COVID-19 have impacted the everyday life of adolescents and young adults, with increased levels of stress and anxiety being reported. Therefore, we report primary care visits due to mental health problems and the use of psychotropic medication in Finland. METHODS: We conducted a nationwide register-based study and included primary care visits with mental health problems (F*-class ICD-10 diagnosis) for patients aged 15-24 years. We calculated incidence for visits and used incidence rate ratios (IRR) for comparisons. Psychotropic medication purchases for patients aged 13-24 years were included. Annual psychotropic medication user prevalence per 1000 was calculated and prevalence rate ratios (PRR) with 95% confidence intervals (CI) were used for comparisons. The years 2020 and 2021 were compared to the pre-pandemic reference year 2019. RESULTS: A total of 396534 visits to primary care due to mental health problems were included. Annual visit incidences per 1000 were 151.7 in 2019, 193.6 in 2020, and 306.7 in 2021, indicating a 28% (IRR 1.28, CI 1.27-1.29) increase from 2019 to 2020 and a 102% (IRR 2.02, CI:2.01-2.04) increase from 2019 to 2021. Highest reported increases in 2020 were sleeping disorders (IRR 1.79, CI 1.72-1.87) and anxiety disorders (IRR 1.39, CI 1.37-1.42). Prevalence of antidepressant use increased by 25% (PRR 1.25, CI 1.23-1.26) in 2021. An increase was also seen in the use of antipsychotics (+ 19%, PRR 1.19. CI 1.16-1.21). CONCLUSIONS: The COVID-19 pandemic increased the need for mental health services and medication among Finnish adolescents and young adults. Our health care system needs the capacity to manage the increased number of visits, and we must be better prepared for future crises.

Birth rate among women with fear of childbirth: a nationwide register-based cohort study in Finland.

PURPOSE: The association between fear of childbirth (FOC) and subsequent birth rate is not well studied. The aim of this study is to evaluate the birth rate, and risk for second pregnancy ending in delivery among women with FOC compared to women without FOC in their first pregnancy. METHODS: Data from the National Medical Birth Register were used to evaluate the birth rate after the first pregnancy in women with FOC. Cox regression model was used to evaluate the risk for the second pregnancy ending in delivery in women with FOC compared to reference individuals without FOC. The results were interpreted with adjusted hazard ratios (aHRs) and 95% confidence intervals (CI). RESULTS: In total, 375,619 women were included in this study. Of these, 9660 (2.6%) had FOC in the first pregnancy (exposed group), and 365,959 (97.4%) had no FOC (non-exposed group). In the exposed group, 3600 (37.3%) women had second pregnancy ending in delivery during the study period, and 206,347 (56.4%) had the second pregnancy ending in delivery in the non-exposed group. The risk for the second pregnancy ending in delivery was lower among women with FOC (aHR 0.61, CI 0.59-0.63). CONCLUSIONS: FOC complicates pregnancy and delivery and is strongly associated with lower likelihood to get pregnant again. Therefore, more research should be focused on the optimal prevention of FOC using a standardized procedure of care and treatment for women with FOC.

Trends in Emergency Department Visits and Surgeries due to Traumatic Brain Injury During the COVID-19 Pandemic in Finland.

We aim to evaluate the changes in the incidence of TBI, trauma craniotomies, and craniectomies during the COVID-19 pandemic in Finland. This retrospective register study was conducted at three Finnish hospitals. We retrieved the numbers of emergency department (ED) visits, inpatient admissions, and trauma craniotomies and craniectomies due to TBI in the adult population from 2017 to 2020.We calculated the incidences per 100 000 inhabitants and compared the year 2020 to the reference years (2017-2019) by incidence rate ratios (IRR) with 95% confidence intervals. The incidence of TBI-related ED visits during the study period compared to the reference years started to decrease in March 2020 (IRR 0.86, CI: 0.73-1.02), and the lowest incidence was seen in April 2020 (IRR 0.83, CI: 0.68-1.01). The incidence of ED visits showed a second decrease in December (IRR 0.80, CI: 0.67-0.96). The incidence of concussion decreased during the national lockdown in March (IRR 0.80, CI 0.66-0.97). The incidence of ED visits due to TBI decreased after the declaration of national lockdown in spring 2020 and showed a second decrease during regional restrictions in December. In addition, the incidence of neurosurgically treated TBI decreased during restaurant restrictions in the spring.

Trends in emergency department visits due to back pain and spine surgeries during the COVID-19 pandemic in Finland.

ABSTRACT: We aim to report the incidences of ED visits due to back pain, hospitalizations, and urgent spine surgeries during the first and second waves of COVID-19 in Finland. The number of emergency department visits and hospitalizations due to back pain as well as urgent spine surgeries in the adult population was collected from hospital discharge registers for the years 2017 through 2019 (reference years) and 2020.This study was conducted at three large Finnish hospitals. The monthly incidence with 95% confidence intervals (CI) of emergency department visits and hospitalizations due to back pain and spine surgeries in the three participating hospitals were calculated and compared by incidence rate ratios (IRR).Visits to ED due to back pain decreased during the pandemic. The incidence of ED visits due to back pain was similar in February (IRR 0.95, CI: 0.82-1.10), but a decrease was seen after lockdown began (March IRR 0.67, CI: 0.57-0.78; April IRR 0.65, CI: 0.56-0.76) compared to the reference years. A second decrease in visits was seen after regional restrictions were implemented in October (IRR 0.88, CI: 0.76-1.02). The most common diagnoses were non-specific back pain, lumbar disk herniation, and back contusion. Incidence of non-specific back pain decreased during the lockdown (March IRR 0.65, CI: 0.55-0.78) and regional restrictions (October IRR 0.83, CI: 0.70-0.98), whereas the rates of other diagnoses remained unchanged, and incidences of hospitalizations and urgent spine surgeries remained stable.A clear decrease in ED visits due to back pain was seen during the first and second waves of the pandemic. This decrease was mainly the result of patients with non-specific back pain avoiding visits to the ED. The incidence of specific back pain, hospitalizations, and urgent spine surgeries remained unchanged during the pandemic.

Emergency department visits due to hand trauma and subsequent emergency hand surgery in three Finnish hospitals during the first and second waves of COVID-19 pandemic.

INTRODUCTIONS: The rate of acute hand trauma visits to emergency departments (ED) and surgeries decreased during the COVID-19 lockdown. Our aim was to analyze the influence of national lockdown during the first wave and the regional restrictions during the second wave on the rate of visits to the ED and urgent hand surgeries in Finland. METHODS: Material for this retrospective study was gathered from three Finnish hospitals All ED visits and urgent or emergency surgeries from January 2017 to December 2020 were included. Incidences per 100 000 persons with 95% confidence intervals (CI) were calculated and compared by incidence rate ratios (IRR). RESULTS: The incidence of hand injury was lower after the beginning of the lockdown in March 2020 (IRR 0.70 CI 0.63-0.78). After lockdown ended in May, the monthly incidences of ED visits returned to the reference level. During the lockdown, the incidence of fractures and dislocations was 42% lower in March (IRR 0.58 CI 0.50-0.68) and 33% lower in April 2020 (IRR 0.67 CI 0.57-0.80). The incidence of fracture repair surgeries was 43% lower in March 2020 (IRR 0.57 CI 0.35-0.93) and 41% lower in July 2020 (IRR 0.59 CI 0.36-0.98). Incidence of replantation was 49% higher in March 2020 (IRR 1.49 CI 0.53-4.20) and 200% higher in July 2020 (IRR 3.00 CI 0.68-13.2) but these increases had high uncertainty. CONCLUSIONS: The rate of ED visits due to hand injuries decreased while the rate of emergency hand operations remained unchanged during the national COVID-19 lockdown in spring. After the lockdown, the incidences returned to reference level and were unaffected by regional restrictions during the second wave of pandemic.

The effect of COVID-19 lockdown on the incidence of emergency department visits due to injuries and the most typical fractures in 4 Finnish hospitals.

BACKGROUND AND PURPOSE: COVID-19 lockdowns have affected personal mobility and behavior worldwide. This study compared the number of emergency department (ED) visits due to injuries and typical low-energy fractures in Finland during the COVID-19 lockdown period in spring 2020 to the reference period in 2019. PATIENTS AND METHODS: The data was collected retrospectively from the electronic patient records of 4 hospitals covering 1/5 of the Finnish population. We included the patients who were admitted to a hospital ED due to any injury during the lockdown period (March 18-May 31, 2020) and the reference period (March 18-May 31, 2019). We compared the differences between the average daily ED admissions in the 2 years using the zero-inflated Poisson regression model. RESULTS: The overall number of ED visits due to injuries decreased by 16% (mean 134/day vs. 113/day, 95% CI -18 to -13). The number of ED visits due to wrist fractures decreased among women aged over 50 years by 40% (CI -59 to -9). Among women, the number of ED visits due to ankle fractures decreased by 32% (CI -52 to -5). The number of ED visits due to fractures of the upper end of the humerus decreased by 52% (CI -71 to -22) among women. The number of ED visits due to hip fractures increased by 2% (CI -16 to 24). INTERPRETATION: Restrictions in personal mobility decreased the number of ED visits due to injuries during the pandemic. The effect can mainly be seen as a decreased number of the most typical low-energy fractures among women. In contrast, lockdown restrictions had no effect on the number of hip fractures.

Prioritizing Elective Surgery During the COVID-19 Pandemic Has Caused Age-Related Inequality: a Multicenter Study

The concern has been that this prioritization has resulted in age-related inequality between patients, with the older population suffering the most. The aim of this multicenter study was to examine the differences in incidence and waiting times of elective surgeries by age during the SARS-CoV-2 coronavirus disease (COVID-19) pandemic in Finland. Data on elective surgery (88 716 operations) were gathered from three Finnish public hospitals for the years 2017–2020. Surgery incidence and waiting times stratified by age groups (younger than 18, 18 to 49, 50 to 69, and 70 or older) were examined, and the year 2020 was compared to the reference years 2017–2019. The mean annual, monthly, and weekly waiting times were calculated with 95% confidence intervals (CI). The first COVID-19 wave decreased surgery incidence most prominently in patients younger than 18 (incidence rate ratio [IRR] 0.64, CI 0.60–0.68) and 70 or older (IRR 0.68, CI 0.66–0.70). After the first wave, the incidence increased in patients aged 50 to 69 and 70 or older by 22% and 29%, respectively. Among patients younger than 18, the incidence in 2020 was 15% lower. In patients younger than 18, waiting times were at mean of 43% longer in June to December compared to the reference years. In patients aged 18 to 49, 50 to 69, and 70 or older, waiting times increased in May but recovered to normal level during fall 2020. COVID-19 decreased the incidence of surgery and led to increased waiting times. Clearing of the treatment backlog started with older patients which resulted in prolonged waiting times among pediatric patients.

Incidence of pediatric injury visits decreased while trauma surgeries remained stable during the first and second waves of the COVID-19 pandemic in Finland: a register-based study.

Introduction: The COVID-19 pandemic has reduced pediatric emergency department (ED) visits and surgeries. This study evaluates the incidence of pediatric trauma ED visits and surgeries in Finland during the first and second waves of the pandemic. Methods: Three large Finnish hospitals, covering one-sixth of the Finnish pediatric population, participated. Data on all ED visits and trauma surgeries between January 2017 and December 2020 were collected from hospital discharge registers. Monthly incidences with 95% CI were calculated per 100 000 person-months by Poisson exact method and compared by incidence rate ratio (IRR). Results: During the lockdown the incidence of head injuries (IRR 0.19, 95% CI 0.04 to 0.87), sprains (IRR 0.25, 95% CI 0.14 to 0.46), and fractures (IRR 0.36, 95% CI 0.25 to 0.51) decreased in the 13-17 years age group. In the 4-12 years age group a 55% decrease (IRR 0.45, 95% CI 0.22 to 0.96) in head injuries was observed. During the period of regional restrictions a subtle decrease in head injuries was seen in the 13-17 years age group (IRR 0.26, 95% CI 0.09 to 0.78). During the lockdown in March 2020 the incidence of fractures decreased in the oldest age group (13-17 years) (IRR 0.62, 95% CI 0.46 to 0.85), while a rebound in incidence was seen at the end of the lockdown period in June. Conclusion: The nationwide lockdown and the cancellation of sports and other hobbies markedly decreased the injuries among children aged 13-17 years, while the decrease was lower among children aged 4-12 years. Cancellation of sports and hobbies did not affect patients under 4 years of age.

Emergency department visits due to coronary artery disease during COVID-19 in Finland: A register-based study.

Aims: This multi-centre study examined the effects of restricted availability of health-care services during the COVID-19 pandemic on treatment of coronary artery disease (CAD) in Finland. Methods: Data on referrals to cardiological units (n=81,008), emergency department (ED) visits (n=10,001) and hospitalisations (n=8654) for CAD were collected from three large Finnish hospitals, and incidences were calculated per 100,000 persons for the years 2017 through 2020. Year 2020 was compared to the reference years 2017-2019 by incidence rate ratios (IRR) with 95% confidence intervals (CI). Results: Referrals to cardiological units decreased after the onset of the pandemic in March to May (IRR=0.83, 95% CI 0.81-0.86). ED visits due to acute coronary syndrome decreased during the first months of the pandemic, with the overall annual incidence 2-14% lower than in the reference years. ED visits due to chronic CAD increased prominently during in April and May compared to the corresponding months in the reference years (IRR=1.49, 95% CI 1.23-1.81 in April; IRR=1.57, 95% CI 1.32-1.89 in May) and remained elevated until the end of 2020, with an increase in annual incidence of 17% (IRR=1.17, 95% CI 1.11-1.24). Conclusions: The first COVID-19 wave decreased ED visits due to acute coronary syndromes and increased those due to chronic CAD. The changes in referral and ED visit incidences during the second wave were rather modest.

Tympanostomies and tonsillar surgery in children during the COVID-19 pandemic in Finland.

OBJECTIVE: To assess the impact of social restrictions due to COVID-19 on the number of tympanostomies and tonsillar surgeries in children. METHODS: Incidences were calculated per 100 000 children for tonsillar surgery and tympanostomies in 2020 and compared to the mean incidence of referral years 2017 to 2019 by incidence rate ratios (IRR) with 95% confidence intervals (CIs). Median waiting times were also compared. RESULTS: Before the lockdown, tonsillar surgery incidence was 33.4/100000 (IRR 1.14, CI 0.76-1.71) in February 2020. After the lockdown began, the incidence of tonsillar surgery was 1.4/100000 (IRR 0.04, CI 0.01-0.15) in April. In June, tonsillar operation incidence started to increase (20.4 per 100 000). The incidence of tympanostomies was 81% lower (IRR 0.19, CI 0.09-0.39) in April 2020 and 61% lower (IRR 0.39, CI 0.22-0.69) in August 2020 than in 2017-2019. These incidence rates remained lower all year (December 2020 IRR 0.13, CI 0.05-0.33). Median waiting time for tonsillar surgery was 3.3 months in 2020 and 1.6 months in 2017 to 2019; P <.001, and for tympanostomies 1.3 months in 2020 and 1.0 months in 2017 to 2019, P <.001. The referral rate to otorhinolaryngology during the severest restrictions was 35% lower in April and May 2020 compared with the reference years. CONCLUSION: This study suggests that the restrictions against COVID-19 reduced the incidence rates of tonsil surgery and tympanostomies in children. Also, the lockdown and cancellations of elective operations in spring 2020 led to increased waiting times. These findings may help in preparing for future pandemics.Level of evidence: Level 3.

The impact of the COVID-19 pandemic on waiting times for elective surgery patients: A multicenter study.

BACKGROUND: A concern has been that health care reorganizations during the first COVID-19 wave have led to delays in elective surgeries, resulting in increased complications and even mortality. This multicenter study examined the changes in waiting times of elective surgeries during the COVID-19 pandemic in Finland. METHODS: Data on elective surgery were gathered from three Finnish public hospitals for years 2017-2020. Surgery incidence and waiting times were examined and the year 2020 was compared to the reference years 2017-2019. The mean annual, monthly, and weekly waiting times were calculated with 95% confidence intervals (CI). The most common diagnosis groups were examined separately. FINDINGS: A total of 88 693 surgeries were included during the study period. The mean waiting time in 2020 was 92.6 (CI 91.5-93.8) days, whereas the mean waiting time in the reference years was 85.8 (CI 85.1-86.5) days, resulting in an average 8% increase in waiting times in 2020. Elective procedure incidence decreased rapidly in the onset of the first COVID-19 wave in March 2020 but recovered in May and June, after which the surgery incidence was 22% higher than in the reference years and remained at this level until the end of the year. In May 2020 and thereafter until November, waiting times were longer with monthly increases varying between 7% and 34%. In gastrointestinal and genitourinary diseases and neoplasms, waiting times were longer in 2020. In cardiovascular and musculoskeletal diseases, waiting times were shorter in 2020. CONCLUSION: The health care reorganizations due to the pandemic have increased elective surgery waiting times by as much as one-third, even though the elective surgery rate increased by one-fifth after the lockdown.

Severely injured patients do not disappear in a pandemic: Incidence and characteristics of severe injuries during COVID-19 lockdown in Finland.

Background and purpose - COVID-19 lockdowns have resulted in noteworthy changes in trauma admissions. We report and compare the incidence and characteristics of severe injuries (New Injury Severity Score [NISS] > 15) during the COVID-19 lockdown in Finland with earlier years.Methods - We retrospectively analyzed incidence rate, injury severity scores, injury patterns, and mechanisms of injury of all severely injured patients (NISS >15) in 4 Finnish hospitals (Tampere University Hospital, Kuopio University Hospital, Central Finland Hospital, Mikkeli Central Hospital) during the 11-week lockdown period (March 16-May 31, 2020) with comparison with a matching time period in earlier years (2016-2018). These 4 hospitals have a combined catchment area of 1,150,000 people or roughly one-fifth of the population of Finland.Results - The incidence rate of severe injuries during the lockdown period was 4.9/105 inhabitants (95% CI 3.7-6.4). The incidence rate of severe injuries during years 2016-2018 was 5.1/105 inhabitants (CI 3.9-6.5). We could not detect a significant incidence difference between the lockdown period and the 3 previous years (incidence rate difference -0.2 (CI -2.0 to 1.7). The proportion of traffic-related accidents was 55% during the lockdown period and 51% during previous years. There were no detectable differences in injury patterns. During the lockdown period, the mean age of patients was higher (53 years vs. 47 years, p = 0.03) and the rate of severely injured elderly patients (aged 70 or more) was higher (30% vs. 16%).Interpretation - Despite heavy social restrictions, the incidence of severe injuries during the lockdown period was similar to previous years. Notably, a decline in road use and traffic volumes did not reduce the number of severe traffic accidents. Although our data is compatible with a decrease of 2.0 to an increase of 1.7 severely injured patients per 105 inhabitants, we conclude that severely injured patients do not disappear even during pandemic and stabile hospital resources are needed to treat these patients.

The effect of national lockdown due to COVID-19 on emergency department visits.

BACKGROUND: COVID-19 outbreak lead to nationwide lockdown in Finland on the March 16th, 2020. Previous data regarding to the patient load in the emergency departments during pandemics is scarce. Our aim is to describe the effect of national lockdown and social distancing on the number and reasons for emergency department (ED) visits and inpatient admissions in three large volume hospitals prior to and after the outbreak of the COVID-19 epidemic in Finland. METHODS: Data for this register-based retrospective cohort study were collected from three large ED's in Finland, covering 1/6 of the Finnish population. All patients visiting ED's six weeks before and six weeks after the lockdown were included. Pediatric and gynecological patients were excluded. Numbers and reasons for ED visits and inpatient admissions were collected. Corresponding time period in 2019 was used as reference. RESULTS: A total of 40,653 ED visits and 12,226 inpatient admissions were analyzed. The total number of ED visits decreased 16% after the lockdown, whereas the number of inpatient admissions decreased 15% (p < 0.001). This change in inpatient admissions was similar in all participating hospitals. Visits due to back or limb pain decreased 31% and infectious diseases 28%. The visit rate and inpatient admissions due to acute myocardial infarction and strokes remained stable throughout the study period. Interestingly, the rate of inpatient admissions due to psychiatric diagnoses remained unchanged, although the ED visit rate decreased by 19%. The number of ED visits (n = 282) and inpatient admissions (n = 55) due to COVID-19 remained low in the participating hospitals. CONCLUSIONS: Changes in ED visits and inpatient admissions prior to and during the early phase of the COVID-19 outbreak were unpredictable, and our results may help hospitals and especially ED's focus their resources better. Surprisingly, there was a major decrease in the rate of ED visits due to back or limb pain and not so surprisingly in infectious diseases. Rates of acute myocardial infarctions and cerebral strokes remained stable. In summary, stabile resources for the treatment of patients with severe diseases will be needed in hospitals and ED's.
