RESUMEN

Introducción:

La COVID-19 se propaga por vías respiratorias y aerosoles. La pandemia originada por esta enfermedad causa pánico, miedo y estrés en todos los estratos de la sociedad. Al igual que todas las demás profesiones médicas, los dentistas, particularmente los endodoncistas, que están muy expuestos a los aerosoles, pueden mostrar estrés.

Objetivo:

Encuestar a los endodoncistas indios para comprender mejor sus niveles de estrés psicológico durante el confinamiento de la India durante la pandemia de la COVID-19.

Métodos:

Del 8 de abril al 16 de abril de 2020 se realizó una encuesta cerrada en las redes sociales de endodoncia. Se utilizó la técnica de muestreo de bola de nieve. Asimismo, se recolectaron datos demográficos básicos, entorno de práctica y otras informaciones relevantes. El estrés psicológico y la angustia percibida se calcularon a través del índice de angustia peritraumática COVID-19 y la escala de estrés percibido. El análisis de regresión multinomial se realizó para estimar la tasa de riesgo relativo y p ≤ 0,05 se consideró significativo.

Resultados:

Este estudio tuvo 586 endodoncistas indios que completaron esta encuesta. De estos, 311 (53,07 %) eran hombres, 325 (55 %) en el grupo de edad de 25-35 años, 64 % en áreas urbanas, 13,14 % en prácticas individuales y un cuarto de ellos eran residentes. Las mujeres endodoncistas tenían un alto estrés percibido (RRR = 2,46, p = 0,01) en comparación con los hombres, medido por PSS. Los endodoncistas más jóvenes < 25 años (RRR = 9,75; p = 0,002) y 25-35 años (RRR = 4.60; p = 0,004) en comparación con el grupo de edad > 45 años tenían más angustia. Los consultores exclusivos tuvieron RRR = 2,90, p = 0,02, para la angustia leve a moderada en comparación con la normal. Se consideran los factores que impulsan este fenómeno.

Conclusiones:

Durante el cierre debido a la COVID-19, los endodoncistas indios 1-en-2 tuvieron angustia, según lo medido por CPDI y 4 de cada 5 percibieron estrés, según lo indicado por PSS. Nuestro modelo identificó ciertos factores que impulsan el (des)estrés, lo que ayudaría a los formuladores de políticas a iniciar una respuesta adecuada.

ABSTRACT

Background:

The novel 2019 COVID-19 spreads by respiratory and aerosols. COVID-19 driven pandemic causes panic, fear and stress among all strata of society. Like all other medical professions, dentists, particularly endodontists, who are highly exposed to aerosols would be exposed to stress.

Objective:

To survey the Indian endodontists to better understand their levels of psychological stress during the Indian lockdown COVID-19 Pandemic.

Methods:

From 8th April to 16th April 2020, we conducted an online survey in closed endodontic social media using snowball sampling technique, collecting basic demographic data, practice setting and relevant data. Psychological stress and perceived distress were collected through COVID-19 Peri-traumatic Distress Index and Perceived stress scale. Multinomial regression analysis was performed to estimate relative risk rate and p ≤ 0.05 was considered significant.

Results:

This study had 586 Indian endodontists completing this survey across India. Of these, 311(53.07 %) were males, 325(55 %) in the age group of 25-35 years, 64 % in urban areas, 13.14 % in solo-practice and a fourth of them were residents. Female endodontists had high perceived stress (RRR = 2.46, p = 0.01) as compared to males, as measured by PSS. Younger endodontists < 25 years (RRR = 9.75; p = 0.002) and 25-35years (RRR = 4.60; p = 0.004) as compared with > 45 years age-group had more distress. Exclusive consultants had RRR = 2.90, p = 0.02, for mild-to-moderate distress as compared to normal. Factors driving this phenomenon are considered.

Conclusions:

During the lock down due to COVID-19, 1-in-2 Indian endodontists had distress, as measured by CPDI and 4-in-5 of them had perceived stress, as indicated by PSS. Our model identified certain factors driving the (dis)stress, which would help policy framers to initiate appropriate response.

Background

The current pandemic, attributed to a novel severe acute respiratory syndrome coronavirus 2 (SARS CoV2) better known as COVID-19, has affected dental practice, like all other medical services. This virus strain bears a striking resemblance to the 21st century viruses like SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV). COVID-19 is reported to be a zoonotic virus, with bats being the possible origin and pangolins as probable intermediate host. The first transmission probably occurred in an exotic meat rich wet market in Wuhan, China. Following this animal-to-human transmission, the COVID-19 has been spread by human-to-human contact. The interpersonal contact occurs mainly via respiratory droplets/aerosols, saliva and or contact. The role of fecal-oral transmission, through fomites or vertical transmission are yet to be confirmed. Both symptomatic and asymptomatic patients spread the virus, but the latter, may act as super-spreaders, as they do not have symptoms and remain active in the community. The incubation period of COVID-19 is reported to be about 5 to 6 days, with up to 14 days have been reported and this is widely used as cut off days for medical observation and quarantine.1

In India, the first confirmed case of COVID-19 was reported on January 30, 2020.2 As a containment initiative, the nation was placed on a total lock down since early hours of 25th March 2020.3 With the start of phase-1 lockdown, all diagnosed cases of COVID-19 underwent contact tracing and potential contacts, including Health Care Workers (HCW) were quarantined or isolated. As of the writing of this article, the nation continues to be under lockdown as phase-2/3till 3rd May 2020 and the total number of cases on 22nd April 2020 morning, was 19984 COVID-19 positive cases including 640 deaths (http://www.mohfw.gov.in).

Oral health care involves use of aerosol producing devices as well as working in close proximity with the oral mucosa and secretions. The risk of cross infection could be high between dental practitioners and COVID-19 patients.4,5 Following the universal norms, societal and government advisory, most of the dental practices and hospitals in India, have closed operation since 25th March. Only emergency and urgent cases were taken up. Even in such instances, strict and effective infection control protocols were to be followed.4,6,7 In spite of such universal precautions, when a COVID-19 patient or a carrier is treated, the risk of aerosol induced spread of virus appears to higher, creating numerous hot-sites of virus deposition in the operatory.8,9 Among dentists, there is a constant, looming anxiety of encountering a COVID-19 infected patient especially when there is lack or limited of access to personal protective equipment, no proper standard protocol for management and possibility of incurring financial implications in the future due to decreased clinical operation hours.6

Endodontists, who are dental specialists (trained primarily to save the decayed tooth, often through root canal treatment) are at greater risk to encounter the cross-infection because of employment of high-speed rotary instruments generating large volume of aerosols and splatter of saliva, during treatment, increasing the probability of nosocomial spread of COVID-19 . This could endanger endodontists, their patients and the community that they serve.7,10

Widespread of disease, in short time, creates stress and has a psychological impact. In the present COVID-19 crisis, a Chinese general population survey documented more than a third of the respondents manifested psychological stress with 5 % experiencing severe distress.11 Among Indians, in a small general public survey, 80 % of the respondents were preoccupied with the thoughts of COVID-19, while sleep difficulties (12.5 %), paranoid about acquiring COVID-19 infection (37.8 %) and distress (36.4 %) were also reported. There was a perceived mental healthcare need in at least 80 % of participants.12

A study among Chinese HCW exposed to COVID-19 patients reported distress (75 %), depression (50 %), anxiety (45 %), and insomnia(34 %).14 During the SARS COV pandemic, HCW feared contagion and infection of their family, friends, colleagues, were reluctant to work and even contemplated resignation.14 They experienced great deal of stress, anxiety and depression due to lurking uncertainty.15

Till date, the psychological stress perception due to COVID-19 has not been assessed among Indian endodontists though they fall under high-risk group for this infection. This manuscript intends to address this lacunae, from this part of the world. The present study evaluated the patterns of perceived psychological (dis)stress among the Indian endodontists and understand the factors associated with it.

Methods

A pan-Indian online survey for assessing the psychological stress among Indian endodontists was organized during 8th-16th April, 2020. This coincided with the last days of phase1 of Indian lock down and initial days of the extension of lockdown. The exemption for this survey was sought from primary author’s institutional review committee as this was an anonymous survey with no personal identification collected out and carried out during a humanitarian emergencies and disaster, as per Indian Council of Medical Research guidelines.

This self-reportable form in English was designed using simple Google forms and the link shared among Indian endodontists through several endodontic specific, closed social media forums, using snowball-sampling technique. Anonymity was ensured and no personal identification, such as IP address, email IDs or details of COVID-19 exposure were collected. The basic demographics of gender, age group in years (> 25, 25 to 35, 36-45, 45 and above), dental practice setting (solo practice- stand-alone practice engaging in endodontics and all dental treatment; private solo practice with other endodontic consultations and or part of a group practice (PSPC/GP); Consultations - consulting for endodontics exclusively at more than 1 clinic; Teaching and Practice - engaged in academics as well as clinical endodontic practice privately; Trainee under supervision - Residents or postgraduates of endodontics at a recognized dental institution, leading to master’s degree in endodontics) and experience after MDS (Trainee/PG student in endodontics, 0 to 5 years, 6 to 10 years and above 10 years) in years were collected. This survey used 2 previously validated questionnaires - COVID-19 Peritraumatic Distress Index (CPDI) and Perceived Stress Scale (PSS).12,16

The CPDI scale measured the frequency of anxiety, depression, specific phobias, cognitive change, avoidance and compulsive behavior, physical symptoms and loss of social functioning in the past week, quantifying on a scale of 0 to 100. A CPDI score of ≤ 27 had low or no distress, 28 to 51 indicates mild to moderate distress and score ≥ 52 indicates severe distress.12 The PSS inquired about thoughts and feelings, quantified as a scale of 0 to 40 with a score between 0-13 as low perceived stress (PS), 14-26 as moderate PS and 27- 40 was considered to have high PS.17

The data thus captured were entered and analyzed using Stata software, version 14.1 for Windows (Stata Corp, College Station, Texas). Descriptive statistics mean with standard deviation (SD), median for continuous variables and proportions with 95 % confidence interval (CI) for categorical variables was calculated. Association of demographic variables with PS and distress levels obtained by PSS and CPDI scales is assessed by Pearson χ2 test. Magnitude of association of demographic variable with levels of PS/distress was analyzed using multinomial logistic regression and presented as relative risk ratios (RRR) with 95 % CI. Hosmer-Lemeshow goodness-of fit-test was used to assess the model fit. The correlation between the two scales was analyzed using Pearson correlation test. An attempt was also made to differentiate the (dis)stress levels between the phase-1 period (8th April to 14th April 10:00 AM) and after the phase-2 lock down announcement (after 14th April 10:05 AM) using 2-sample T test. In all instances, p < 0.05 were considered statistically significant.

Results

This survey received a total of 586 valid responses from endodontists across India during the study period. Of them 311 (53.07 %) were males and 325(55 %) of the respondents belonged to the age group of 25-35 years. Predominantly the endodontists practiced in urban area (64 %), engaging in solo practice (13.14 %), private & group practice along with consultations (PSPC/GP-23.21 %), only consultations (8.02 %) and academics along with clinical practice (27.65 %). Twenty seven percent of the respondents were endodontic postgraduate students. One fourth (26.79 %) of the respondents had more than 10 years of post Master Degree experience. Among the participants, only 6.48 % used rubber dam always in their regular practice (Table-1).

The correlation coefficient (r) between PSS and CPDI was 0.627 with p < 0.0001. The Cronbach’s α score for PSS was 0.8 and 0.921 for the CPDI. The mean (SD) score for PSS and CPDI was 17.46 (6.73) and 29.91(15.92) respectively. PSS documented perceived moderate PS (score 14-26) among 406 (69.28 %) and high PS in 63 (10.75 %) respondents, whereas CPDI recorded 224 (38.23 %) and 80 (13.65 %) experienced mild-moderate and severe distress respectively (Fig. 1). The distribution of mean (SD), median PSS and CPDI scores for demographic variables are provided in table 1.

An initial analysis using contingency test based on the Pearson χ2 test was conducted to identify the association of stress/distress levels with demographic factors such as gender, age group, practice setting and post Master Degree experience. Almost all the demographic factors were significantly (p < 0.05) associated with the different levels in PSS and CPDI scales (Table 2). As rubber dam usage was skewed among the respondents, it was not considered for further analysis as it could seed bias. As place of practice was not significant among CPDI, it was removed from further analysis.

In the univariate analysis, demographic factors associated with PSS scale (comparison of high vs. low PS) showed females(RRR = 3.47; p < 0.001), specialists employed through only consultations (RRR = 7.18;P = 0.006), postgraduate students under supervised training (RRR = 3.02; p = 0.03), individuals in the age group of < 25 years (RRR = 8.75; p = 0.006), 25-35 years (RRR = 9.64;P < 0.001), specialists with < 5 years of work experience (RRR = 10.52; p < 0.0001) and postgraduate students (RRR = 8.02; p < 0.0001) were significantly associated with increased risk for high PS. Similar trend of association with demographic factors was observed when moderate PS was compared with low PS (Table 3). Multivariate analysis was carried out assessing the factors influencing the PSS scale, for the high PS, as compared to low PS. The model fit test (χ2 = 45.41, p = 0.41), suggested that the model showed adequately fit for the covariates used. Female endodontists (RRR = 2.46, p = 0.01) were significantly associated with an increased risk of high PS as compared to males. Although specialist employed through only consultations was associated with risk of high PS (RRR = 3.59, p = 0.08), it was statistically at borderline significance. Younger age group (25-35years) individuals were observed to experience increased high PS in comparison with older age group (> 45 years) and findings were statistically significant (Table 4).

Univariate analysis of demographic factors associated with CPDI scale (comparison of severe vs. normal distress) documented females (RRR = 1.86; p = 0.01), individuals in the age group of < 25 years (RRR = 6.64; p = 0.003), 25-35 years (RRR = 4.82; p = 0.001), endodontists consulting at clinics only (RRR = 3.99; p = 0.006), specialist with less than 5 years of post Master Degree experience (RRR = 8.54; p < 0.0001) and postgraduate students (RRR = 4.01; p = 0.002) experienced significantly severe distress level. Comparison of mild to moderate with normal distress estimated similar magnitude of associations (Table 3). A model built for multivariate analysis showed adequate fit (χ2 = 59.46; p = 0.06) for the covariates used. In the multivariate analysis, younger age, particularly among the age group of < 25 (RRR = 9.75; p = 0.002), 25-35 years (RRR = 4.60; p = 0.004) in comparison with > 45 years age and postgraduate students under supervised training (RRR = 0.35; p = 0.02) in comparison with solo practitioners had significantly higher risk of severe distress. Specialist employed through only consultations was associated with higher risk for both mild to moderate (RRR = 2.90; p = 0.02) with statistical significance while the severe distress (RRR = 2.34; p = 0.11), was not statistically significant (Table 4).

The mean PSS score in phase-1 period (n = 515) was 18.28 ± 6.45 (17.72 - 18.84) while the same after announcement of phase-2 lockdown (n = 71) was 21.18 ± 6.86 (19.56 - 22.81) with the p = 0.0005. For the CDPI, the scores were 30.96 ± 15.85 (29.59 - 32.33) and 36.18 ± 18.87 (31.72 - 40.65) respectively with p = 0.0113.

Discussion

The social or physical distancing and other COVID-19 restrictions have caused significant disruption globally. This disruptions extends from individuals to families, communities, and whole countries. This disruption also has altered previous familiar concepts and added complexities in all walks of life.17 Mental health issues among HCW in COVID-19 situation has been documented.18,19,20 This altered mental health status stems from several aspects of disturbance from routine. This includes social isolation, interpersonal distancing, heightened need for infection control procedures domestics and at dental operatory, fear of contagion, public perception of COVID-19 stigma, concerns for self/family well-being, potential of acing emotionally charged clinical environments, possible unrealistic public expectations, prevalent cynicism, possibility of patient safety incidents, procedural errors, decreased access to protection gears, lower quality of para-service provision, along with core issues of financial insecurity and potential loss of income.21 Economic impact of COVID-19 pandemic is at a personal, community, national and global level. This burden cannot be underestimated, as it could potentially influence on all other spheres of life.22 Dentists and Endodontists, as an integral part of the society, are not immune from all these impacts. There is dearth of evidence of perceived stress (PS) and distress among dentists, particularly among endodontists, (irrespective of COVID-19 exposure) who are at the highest risk of cross infection.23) For this very purpose, we used two scales, a time tested PSS scale and new, COVID-19 specific CPDI scale were used. Both have been used and published in peer reviewed literature and been accepted, with the former being used for more than three decades. As there was a statistically significant correlation, it could be safely inferred that the COVID-19 scale is reflective of the self-reported psychological distress in COVID-19 situation. However, as the PSS scores have not been used previously in COVID-19 related literature, rendering it impossible to be compared with pertinent literature in this manuscript.

The mean score of CPDI for this exclusive Indian endodontic cohort was 29.91 ± 15.92 which is greater than the Chinese general population 23.65 ± 15.45 but lower than that of Iranian population (34.54 ± 14.92).11,24 The psychological distress among Indian endodontists, during the time of COVID-19 by CPDI was 51.88 % (38.23 % mild to moderate and 13.65 % - severe distress) while estimates of distress from Chinese population (by CPDI) was 35 % (29.29 % mild-to-moderate; 5.14 % severe) and Iranians was 61 %(47.0 % mild-to-moderate; 14.1 % severe).11,24) The difference could be multifold - primarily that the present study had a homogenous cohort of endodontists whereas the Chinese and Iranian cohorts comprised of general public. The other reason is that Chinese and Iranian had a significant number of population infected with COVID-19, unlike India.3,11,24 The biological, anthropological, immunological, socio-demographic and cultural variations could also be accountable. Like the Chinese study, Indian Women endodontists had higher extent of stress while age group is not in agreement with Chinese study.11 Like the Iranian finding, the predictors of distress in India vary from those in China and Iran.11,24 When the PSS was employed, 80 % (69.28 % - moderate; 10.75 % - severe) of Indian endodontists suffered from stress during COVID-19 situation. This is 235 % higher than that of the Indian general public during the same situation.12 The PS proportions are similar to Chinese HCW who were exposed to COVID-19 patients.13

Rubber dam usage among Indian endodontics is skewed, with only 6.48 % of the cohort regularly using it. Also, there are conflicting evidences about the rubber dam’s efficacy in alteration microbial load in aerosols as compared to non-rubber dam use.25,26 Hence, rubber dam usage characteristic was not used in further analysis.

The association of gender, age group, area of practice, practice setting and experience were statistically significant between the levels of (dis)stress using PSS and CPDI. (Table2) As there is no pertinent literature, the present results cannot be supported or refuted.

In the univariate analysis, significance with gender reflects the fact that women, particularly female doctors are vulnerable to distress, which is similar to Chinese cohort.(11, 27) Probably, this COVID-19 adds to the pre-existing stressors.27,28 The significance of gender, was lost in multivariate analysis except for PSS High to low stress comparison, where female endodontists are twice likely to experience high stress than their male counterparts. However, in CPDI, there is no significance (Table 3).

Age group had a statistically significant association with risk of PS/distress, in both the PSS and CDPI. It was found that younger age groups < 25 years, 25-35 years had 3 to 5 times higher risk of moderate and severe PS (PSS scale) in comparison with older age group (> 45 years). Interestingly, 25-35 years age group experienced relatively more stress than < 25 years group. Similarly, according to CPDI, comparatively to > 45 years group, < 25 years and 25-35 years had 9 and 4 times higher risk of severe distress respectively. This is not in concordance with Chinese public where, older population had higher distress.11 It has been reported that age is an important factor in stress and stress reaction.29,30,31 In India, as the age advances, endodontists, possibly acquire financial security and thus have limited stress reaction as opposed to their younger counterparts, who are in the process of financially establishing themselves. The financial uncertainty that the present COVID-19 brings could be a possible reason to this phenomenon.6

Area of practice was significant in association for PSS while for CPDI it was not (Table2). India is known to have skewed distribution of dentist and the urban-rural divide exists for a variety of reasons.31 Possibly, the variation in demographics and dominant stressors could also contribute to this phenomenon. As there was not much significance, this factor was eliminated from further analysis.

Experience post-MDS and age appears to be highly related in terms of clinical decision making skills and job satisfaction, perhaps that comes with experiencing different clinical situations and facing odds - clinically as well at personal front. Hence, with increasing experience, endodontists would be more likely to handle stress efficiently than a novice.32,33 In the present study, experience in endodontics had significant magnitude of association, especially postgraduate students and < 5 years of experience. Since experience post-MDS and age were collinear, this was not included in subsequent model analysis.

Practice setting had a significant influence on the model wherein Endodontists who were exclusively consultants had constantly expressed increased risk for perceived stress (RRR = 5.15 to 8.75, in various situations) as compared to their peers. Practice setting plays a vital role in stress. The stress and job satisfaction levels in group practice or those with multiple models of endodontic practice as compared with solo practice to consultants may vary.29 As compared to stand alone practice endodontists, those pursuing exclusively consultation (more than 1 clinic) had 3 times elevated risk of severe PS/distress levels in both of PSS or CDPI. This probably indicates that financial implication posed by COVID-19 situation is a driver of the (dis)stress. This is further highlighted by the significant difference in PSS and CDPI scores during phase-1 and after announcement of phase-2.

All other practice settings, excluding postgraduate students (trainees) and consultants, would have additional avenues of income. Endodontists who rely exclusively on consultations, would not have means or would find it very difficult to practice endodontics during COVID-19 situation. This sudden, downward spiral in income could be major driving force for the elevated (dis)stress in this subgroup. It is also observed that trainee endodontists also have elevated risk of stress as compared to solo practitioners. It has been documented that the dental students have higher stress.30 In the present situation, shifting to a different platform of education, risk of contagion, fear or uncertainty of education and future practice avenues may cause an acute stress on the endodontic trainees/residents. This is captured by the PSS while in CPDI, they have a RRR of 1.67 (mild-moderate to normal) and 0.35 (severe to normal) as compared to solo practitioner, albeit without statistical significance, indicating this stress may not be exclusive to COVID-19 .30 In the model age, gender, and practice setting had varying degree of risk with statistical significance.

In COVID-19 situation, as compared to Indian public (34 %), Indian endodontists in present cohort exhibit higher degree of perceived stress and about 4 in 5 Indian endodontists are perceiving COVID-19 to be a major stressor.13 The CPDI model analysis indicate the age and practice setting are major determinants of the distress. It could be postulated that the financial insecurity and fear for getting COVID-19 infection through dental operatory aerosol, as one of the possible major driving force of the distress among endodontists.

There is also news report of brewing concerns among Indian public for the need of dental clinics to carter for their urgent oral care needs. Given this scenario, such news could incrementally add to the existing cynic concern among Indian endodontists. Even otherwise, stress is common in Indian dentists.34 This distress (stress and distress often used interchangeably, in present context), could be a transient phenomenon related to COVID-19. This may subside when the COVID-19 situation dampens or when endodontists learn and adapts to COVID-19. But if this distress is in excess, as observed in about 13 % of endodontists or persists well after COVID-19 fades, it would need to be viewed as a part of a pathological psychological process, which would need professional help.35 The impact of the COVID-19 on Indian endodontists with features of insomnia, irritability, anxiety, depression, somatoform manifestation has to be carefully screened to identify and treat evolving mental disorders, especially in the most vulnerable ones.

The limitation of this study would include self-reporting bias, non-consideration of Indian states (as the whole country was under lockdown, unlike China), role of other stressors and COVID-19 exposure. Further studies, in this direction have to explore role of other possible confounders as well as factor that could meaningfully add to present models.

Conclusions

Psychological (dis)stress among Indian endodontists in COVID-19 situation are presented for the first time, to the best of our knowledge. As compared to public, there is higher prevalence of stress among Indian endodontists. Those endodontists that are either trainee or those who exclusively go for consultations, females and younger aged have higher risk for (dis)stress. The endodontic and dental key opinion leaders need to factor in the high degree of (dis)stress among endodontists, evolve policies and guidelines such that there is provision for care after the initial coping. They need to work with authorities to develop and coordinate profession focused psychological first aid with adequate space for monitoring, screening, referral and targeted intervention such that the (dis)stress is reduced. The focus should be developing COVID-19 lock down exit strategies for dentists, formulating better working protocols for sterilization/disinfection, cheaper, faster, reliable screening and diagnostic tools, making barrier materials available and a robust mental health support system.
