Abstract

Some doctors with severe congenital colour vision deficiency (CCVD) may experience difficulty in colour discrimination that can affect their decision-making. In the absence of evidence-based guidelines, learners with CCVD are arbitrarily debarred from specialising in some disciplines. This cross-sectional, anonymous, questionnaire-based study asked specialists from all over the country if doctors with CCVD should avoid specialising in their respective disciplines. Of 218 responses, 80 (36.7%) said they should avoid it, citing colour discrimination as critical. The 32 (14.7%) participants who were unsure and 106 (48.6%) who said that CCVD would not be a problem gave reasons that mirrored those in the literature: the degree of deficiency is variable; experience helps; automation, history-taking, close observation, good illumination, contrast, touch, and peer-corroboration can reduce dependency on colour. Awareness of the deficiency and finding ways to compensate for it during training may mitigate errors and safeguard patients. Instead of blocking people with CCVD from admission to some specialties, specialists should consider these findings and support learners who are aware of their deficiency and still wish to specialise in a particular discipline.

Introduction

Colour is an important diagnostic criterion in many clinical and laboratory situations (1, 2, 3, 4, 5). The literature shows that doctors with colour vision deficiency (CVD) may experience difficulties in colour discrimination during practice; conversely, it is also seen that over time they are able to perform reasonably well by using other important clues (6, 7, 8). In India, students with congenital colour vision deficiency (CCVD) are not debarred from joining the undergraduate medical course; thereafter, in the absence of uniform guidelines on their fitness to join a postgraduate course, they may face a stumbling block when a postgraduate admissions committee debars them on the grounds of their having a deficiency in colour vision. In the absence of evidence-based guidelines, decisions to debar them from joining a specialisation of their choice are based on arbitrary grounds and are made by specialists who do not themselves have CCVD. These decisions risk being challenged in the courts (9). This study seeks to examine what specialists perceive about the issue of students with CCVD joining medicine and whether they feel that CVD could hamper practice in their particular specialty. The study might help in formulating an advisory for students with CVD until a better-informed advisory can be prepared, once more physicians with CVD come forward without fear of stigma to share their experiences.

Methods

This was a cross-sectional, observational, online study using a questionnaire, conducted from June 2018 to March 2019. Specialists from all disciplines were recruited through social media, from medical education and other listservs and through email, using a flyer. They were requested to complete the questionnaire only if they fulfilled all three inclusion criteria: had completed their post-graduation; were working in the field of their specialisation for at least eight years after post-graduation; and were based in India. The flyer detailed the need for the study and the procedures involved. Participants were directed via a link to a questionnaire on Google forms that sought to assess, among other things, their perceptions on whether CCVD could hamper practice in their own specialty. Overall, less than 10 minutes of participation was required at a time that suited their convenience.

Sample size

For the purpose of calculating sample size, we considered respondents as belonging to one of three groups: Pre- and Para-clinical (PP: Anatomy, Physiology, Biochemistry, Pathology, Pharmacology, Forensic Medicine, and Microbiology), Medical specialties (MM: Community Medicine, General Medicine, Dermatology, Radiology, Psychiatry, Paediatrics, and Anaesthesiology) and Surgical specialties (SS: Ophthalmology, Otorhinolaryngology, General Surgery, Obstetrics & Gynaecology, and Orthopaedics).

In the absence of historical data, we took the chance that 50% of respondents might say that learners with CCVD should not join their specialty. Thus, keeping 10% absolute error as acceptable, the sample size for each group was calculated to be at least 100. However, since there are generally fewer faculty in the pre- and para-clinical streams, and there are fewer broad specialties in surgical as compared to medical disciplines, we determined that we needed to recruit 75 respondents from PP, 75 from SS, and 100 from MM specialties (Total 250 respondents).

Ethics

Waiver of ethics clearance was received from the authors’ institutions in view of the online method of data collection where identifying data and face-to-face interaction was not sought (IEC-HR/2018/33/3/ and 242(16/2018)/IEC/PGIMER/RMLH/718/18). The study was thus completely confidential. There was no risk involved for the participants, and they were free to withdraw from the research at any time, without any penalty. The data was securely downloaded and maintained in a password-protected Excel document.

Data analysis

A descriptive analysis was done: proportions, averages, and standard deviations were calculated using SPSS version 16. Association between responses (Yes/No) and the different items of the questionnaire were determined using the Chi-square and Fisher Exact test.

Results

The number of respondents was 251, of whom 218 (86.9 %) fulfilled all three eligibility criteria. The responses of the 218 participants with respect to the primary objective – should medical students with CCVD join their specialty? [should not: n = 80 (36.7%); unsure: n = 32 (14.7%); should join: n = 106 (48.6%)] – were found to be comparable with those of the 33 who did not fulfill all three criteria [should not: n = 9 (27.3%); unsure: n = 2 (6.1%); should join: n = 22 (66.7%); p=0.15)]. Nevertheless, we chose to stay committed to the original inclusion criteria; thus, the following results pertain to 218 respondents. Of some interest was one ineligible respondent who did not continue in the profession after graduating because of CCVD. The observations of this participant (Respondent-X) are also presented.

There were 65 respondents (29.8 %) from the PP specialties [Anatomy = 8, Biochemistry = 11, Physiology = 17, Pathology = 12, Microbiology = 5, Pharmacology = 7, and Forensic medicine and Toxicology = 7]. MM comprised 86 (39.5 %) respondents [Community Medicine = 9, General medicine = 5, Paediatrics = 11, Anaesthesia = 35, Dermatology = 6, Psychiatry = 1, Radiology = 6, Superspecialties = 13]. SS [Ophthalmology = 19, Otorhinolaryngology = 9, General surgery = 8, Obstetrics and Gynaecology = 15, Orthopaedics = 6, Superspecialties = 10] had 67 (30.7 %) respondents.

One person in each broad group had been diagnosed with CCVD (one Forensic Medicine specialist, one paediatrician, and one ophthalmologist). In addition, three people (an anatomist, a biochemist, and a microbiologist) in group PP, and a paediatrician in group MM suspected that they might be colour vision deficient (CCVD-unconfirmed ) but had not got themselves tested.

Based on their own experience during the medical course, only 33 (15.1%) participants felt that students with CCVD should avoid it. Respondent-X, too, shared that opinion. Most others (n = 140; 64.2% – including two of the three doctors with CCVD and all four CCVD-unconfirmed, opined that they should be allowed to join, while 45 (20.6% – including the Forensic Medicine specialist with CCVD) said they were not sure about it.

When asked if, based on their experience in their own specialty, students with CCVD should avoid taking up their specialty, overall, 106 (48.6%) respondents thought they should specialise in it if interested. Eighty (36.7%) respondents said no, while 32 (14.7%) said they were unsure. The reasons they gave for their choices are summarised in Table 1. Some respondents gave no reason.

Nearly half (106; 48.6%) of the respondents felt that, over time or with training, doctors with CVD could learn to use colour-independent cues (like detailed history, brightness and contrast, close observation, touch, etc.) to avoid errors in their particular specialty. This included two CCVD-unconfirmed (a microbiologist and a paediatrician) and all three respondents who were diagnosed with CCVD. More than one-third of the respondents (80; 36.7%) were unsure about the potential for this [including two CCVD-unconfirmeds (an anatomist and a biochemist), and Respondent X].

When asked whether they would be comfortable if their diagnostic report was signed by a microbiologist / pathologist / biochemist / haematologist / radiologist with CCVD, many said no (126; 57.8%) and 41(18.8%) were unsure. On the other hand, when asked whether they would be comfortable if they knew that their treating physician had CVD, about half said yes (110; 50.5%), while 32 (14.7%) were unsure. Finally, with respect to CCVD surgeons, 122 (56.0%) said they would not be comfortable if their treating surgeon had CCVD, while 36 (16.5%) felt unsure. Their reasons, paraphrased for brevity, are displayed in Tables 2–4. Some respondents gave no reason.

Based on their experience during their MBBS postings in the various departments, respondents were asked to indicate all the specialties that they thought a doctor with CCVD could have difficulty in. They were requested to select all that they thought were applicable. Their choices are displayed in Table 5.

Discussion

We recruited physicians from all over the country to give their opinion on whether a person with CCVD would be able to perform in their specialty or not. Ideally, such a study should have involved people with CCVD, and we had hoped that, since their identity was not solicited, many such doctors would respond. That was not the case; however, while seven is a disappointingly small number, the proportion is not unexpected – at about 3.2% (7/218 eligible respondents; 8/251 total respondents), this compares well with a previous study on medical students, where the prevalence of CCVD was found to be 3.4% of the 1022 students screened by the Ishihara test (1).

We were intrigued about why the four doctors who suspected they had CCVD had not got themselves tested. It highlights that all universities do not mandate testing during admission to the course. Why the respondents did not voluntarily ask for testing may be due to the stigma associated with the diagnosis; the fact that they were managing fine in practice and felt no need to get labeled; or, perhaps, the test was not easily accessible where they practised (10, 11, 12). Since we did not record identifying data in the questionnaire, it was not possible for us to inquire after the real reason, nor could we confirm through testing if they indeed had CCVD, so we thought it best not to speculate any further on this aspect.

Respondents’ views on people with CCVD in medicine

CCVD and the undergraduate course

As far as people with CCVD joining the medical course was concerned, only 15% were unequivocally opposed to it. Of the eligible doctors with CCVD/CCVD-unconfirmed, six out of seven endorsed their inclusion in the course, while one was uncertain. Respondent-X, however, opposed it. This was a person who had changed professions because of the CCVD. It is impossible to say what motivated the move out of medicine, but some thoughts are: he may have had a greater severity of CVD; may have faced stigma during the course; may not have been offered positive counseling or mentoring, or, on the contrary, may have received advice to quit; he and/or his teachers may not have known about the concept of reasonable accommodation for the congenital deficiency (2, 5, 7, 10, 13). Reasonable accommodation, a relatively recent concept in the Indian consciousness, refers to making appropriate degrees of adjustments, within reasonable limits that do not burden the institution/department/faculty, so that learners with CCVD are able to mitigate any disadvantage due to their disability (12). Indeed, teachers could assist learners in finding ways to use cues other than colour (contrast, morphology, texture, etc) early in the medical course (7, 14). We speculate that Respondent-X might have stayed on in the profession if support and reasonable accommodation had been provided, assuming that he would have been open to declaring his condition to the faculty. For all we know, he might have ended up doing very well as a medical practitioner (7).

CCVD and the postgraduate course

The same optimism was not seen when it came to specialty choices – only about half the respondents believed their specialty would be viable for learners with CCVD to practise in. The reasons they gave were illuminating. Broadly, the naysayers stated that it would cause difficulty in recognising coloured cues and colour changes (in the laboratory, in clinics, on alarms and monitors, and during surgery), including in the diagnosis of bleeding. The impression was that colour was paramount in the practice of medicine. It certainly is, but diagnosis is a complex process and involves many other factors apart from colour (5, 15); besides, there are ways to circumnavigate the limitations which have been described in the literature and were also brought out by the other respondents in our study; these are discussed below.

The fear of the naysayers was counterbalanced by those who believed that CCVD would not impact practice in their specialty because of the automation of tests and advanced monitoring equipment – some with audible signals; moreover, one could effectively focus on colour-independent signs and patterns to compensate for the CCVD. Most encouraging was their outlook that people with CCVD adapt to their deficiency and that their skills are honed through repetitive, reflective practice. This information is augmented by their belief (nearly half the respondents, including the three with diagnosed CCVD) that, over time or with training, doctors with CCVD could learn to use colour-independent cues (like detailed history, brightness and contrast, close observation, touch, etc.) to avoid errors. Others also felt that people with CCVD have their own ways of perceiving colours and noticing colour changes which are different from those of colour normal individuals. Some seemed to understand that the type and degree of CCVD would dictate how much it affected practice. Five respondents, who had worked with doctors with CCVD, were particularly confident of their ability to manage competently. This belief mirrors that from around the globe where physicians – some of them with CCVD – write about ways of coping so as to maximise competence and minimise risk to patients (1, 2, 3, 4, 13, 16). Also encouraging was the fact that some respondents with CCVD and CCVD-unconfirmeds (two paediatricians, one forensic medicine specialist, and one microbiologist) felt there would be no problem if a person with CCVD took up practice in their specialty. They could have been biased in favour of others with the condition; however, as shown earlier, the literature supports them.

CCVD and medical practice

To get an in-depth idea of how respondents really viewed the issue, we asked if they would be comfortable being tested/examined/operated on by a doctor with CCVD. Again, as mentioned earlier, at least half said they would not be comfortable when it came to their own health; the reasons they gave (Table 2) seem to centre around their belief that diagnostics and medical/surgical interventions were heavily dependent on an ability to distinguish colour differences. On the other hand, those who were unsure and those who were completely comfortable with the idea gave reasons that suggested they recognized the following with respect to doctors with CCVD (Tables 3 and 4, including some respondents with CCVD/CCVD- unconfirmed): the degree of deficiency is variable; the condition being congenital, people have adapted to a different way of seeing by the time they join medicine; repeated practice and attention to other details/clinical cues and to symptoms and signs help; availability of sophisticated instruments and equipment precludes the need for excellent colour vision; and working in teams allows peer consultation in case of doubt. This is indeed the case as the literature shows (1, 2, 3, 8, 13, 16, 17, 18).

The “safe” disciplines

Table 5 suggests that there are many clinical disciplines (lower half of the list) that most respondents think are not likely to pose problems to a practitioner with CCVD. However, other disciplines are likely to be difficult for a person with CCVD: in order of greater to lesser difficulty, these are Ophthalmology, General Surgery, Dermatology, Obstetrics and Gynecology and Otorhinolaryngology. Similarly, pre- and para-clinical subjects like Pathology and Microbiology could be problematic. Though some of the reasons our respondents gave are supported by the literature (see preceding paragraph), this list is based on the subjective opinion of practitioners and may not represent reality; moreover, two of the reasons they gave make lists such as this one redundant: the degree of deficiency is variable, and no one discipline is exclusively and entirely dependent on colour vision (2, 10).

To exemplify this, consider a few of the disciplines at the top of the “problematic” Table 5. The concerns of our participants with Pathology and Microbiology is understandable since both depend on special stains to an extent, which might be problematic if the stains fall in the colour spectrum that is affected; however, the disciplines depend even more on a sound knowledge of morphology (8, 14) and on the associated clinical history (5, 19). Moreover, the acumen can be strengthened with the use of filters that may help people with CCVD (18) and by sharing the diagnostic test results for peer corroboration (these days, this can be done virtually if the colour deficient diagnostician works in isolation) (8). Biochemistry is lower down in the list of undesirable specialties, probably because respondents believed that automation of biochemical tests makes colour vision redundant.

Ophthalmology and General Surgery are the next two specialties in the list. For ophthalmologists with a severe deficiency, problems may arise when it comes to detecting pigment versus blood in a fundus examination, although this differentiation can be aided with the red-free filter available in the Ophthalmoscope (16). There may still be difficulty in noticing the colour of a bruise and colour changes of the conjunctiva or sclera in conjunctivitis, anaemia, or jaundice; however, a high index of suspicion based on the history and other findings can circumvent errors. Many surgical interventions on the anterior segment involve minimal to no bleeding (cataract surgery, especially phacoemulsification, and corneal laser procedures, for example), allowing eye surgeons with CCVD to flourish in these sub-specialties. As reported by an optometrist with CCVD and others, it is entirely possible to choose an area of Ophthalmology in which to practise safely: one that does not depend on a critical ability to discriminate between colours (16, 20). Though our respondents felt it would need good colour discrimination, general surgery has not been reported in the literature as being a problem for people with CCVD. Apart from a difficulty in detecting bile or blood in vomitus, or blood in stools, no other difficulty has been attributed to CCVD. Indeed, taking an example from real life, a well-respected and prolific surgeon with CCVD who is credited with establishing the field of Gastrointestinal Surgery in the country decades ago has openly shared the fact that he has CCVD (21, 22). Apparently, an understanding of one’s particular deficiency, followed by practice to mitigate its influence on decision-making and using of other cues, including a knowledge of anatomy and good illumination, is the way to practise safely (1, 3, 20). The strategies discussed in this section could be broadly applied to all surgical disciplines. In addition, with the advent of robotic technology to assist surgeons, where the surgical field is displayed on a computer screen, perhaps filters can be inbuilt to help compensate for colour deficiency. With awareness, with practice, and with the use of technology, CCVD could well turn out to be nothing more than a “mild inconvenience” (8). The fact that CCVD is not classified as a specified disability in the Rights of Persons with Disabilities Act, 2016, reinforces this concept (23).

In the field of Dermatology, as in other medical specialties, detecting the presence or defining the extent of erythema could be a problem; however, paying attention to symptoms, to the morphology of the lesion and its location, and to the surface of the skin, using filters and good illumination, and asking for corroboration, sometimes even from the patient, are all ways to minimise errors (7, 8, 16, 18).

Convincing trainers to provide reasonable accommodation to learners with CCVD

The evidence – discussed in the preceding paragraphs – in support of safe practice by doctors with CCVD, who are aware of the condition and take care to compensate for it, may give a direction to the opinions of those who are unsure if training and experience could help. The key is to be aware of the colour deficiency and to learn to compensate for it. Learners with CCVD do make more errors under study conditions than those with normal colour vision (1, 8, 15, 17); however, it may not directly translate into having an adverse impact on diagnosis and treatment at the bedside or in the operation theatre (5, 19). After all – and this needs to be understood –even people with normal colour vision make errors (1); also, it is recognised that medical errors occur when multiple factors converge (24). During the medical course, learners could be encouraged to explore their limitations, if any; be given compensatory time where needed (say 15 minutes extra per hour for histology exams); allowed the use of colour vision aids like filters and screens; and be helped to find other cues/creative ways to compensate for the CCVD. This accommodation, made within reasonable limits, would be of enormous help in building confidence, and it may prevent errors.

Potential accommodations include the use of gray-scale microscopes; assistive technology with Daltonising algorithms, Chromagen and true colour-display technology; close observation and cross checking; using green instead of red laser pointers; and ensuring black coloured arrows and pointers on lecture slides, among others (25).

Following an ethical path where health practitioners with CCVD are concerned

The data shows that the specialization options for a medical student with CCVD are not as limited as one might imagine; however, the disparity in the views within departments means that, in the absence of policy guidelines, whether students ultimately get to join the specialty of their choice depends on who is sitting at the decision-making table. If it is a person who believes that colour is not only a critical but also a non-negotiable requirement for practice in that specialty, then the learner is doomed. This, indeed, happens; two of the authors (UD and SS) have been approached by physicians with CCVD who were denied residency jobs (personal communications). Contrast this with a decision-maker who believes that colour is only one of many tools available to a practitioner; that non–colour-dependent cues are equally important; and that learners with CCVD have mechanisms in place, from birth onward, that allow them to function fairly well in a way that is different from the behaviour of people with normal colour vision. In such a case, the learner would be able to specialize in the subject of his choice. It seems unfair to base other peoples’ careers on one’s arbitrary beliefs, but this does happen. Members of admissions committees, of medical boards, and of job selection committees are not entirely to blame since the country does not yet have a clear-cut policy on which specialties a person with CCVD can train for or work in. In the absence of guidelines, members must use their own judgment – but as we can see from our own data, the decisions could go either way.

How do we decide who is right? Undeniably, patient safety is important, as highlighted by some of the naysayers, but where is the evidence that doctors with CCVD endanger patients? On the contrary, there are reports of eminent and competent doctors who, incidentally, also have CCVD (14, 21, 22). When we speak of potential limitations due to CCVD, do we stop to consider the advantages that colour deficiency may bestow (26)? Do we consider how much benefit would accrue from making a reasonable accommodation for learners until they learn to navigate the deficiency as applied to the practice of medicine? After all, they have already been navigating a world that is geared for colour normal individuals and not for universal access. And they have been adapting to the requirements of such a world since the day they were born, compensating in cognitive and several other ways for the deficiency (13, 27). Is it fair to consider their way of seeing colours as abnormal and hence to suggest it be treated? While the Medical Council of India is silent on the matter of treatment, the Indian Nursing Council has declared that such students could join the nursing course provided that they wore colour corrective contact lenses or spectacles (28). The decision may not be without its own ethical dilemma. Persons who have spent the first two decades or so of life adjusting to a certain way of seeing colours, may find that corrective lenses impact their learning because now the colours they see are completely new to them. It is important to understand that they did not become colour blind the day they were tested, but have always been that way since birth. That is their normal, they grew up with it, their brains developed around it. A new spectrum may confuse and shock the brain (27). Regulators need to determine if it would be fair to force learners to take on a whole new colour spectrum when, for all we know, they may make no errors with their usual spectrum. Far from helping them, colour corrective lenses and spectacles may be counterproductive and may remove all the advantages they have acquired with respect to other senses like touch and other clues like hue and luminescence. Besides, existing colour-corrective glasses are costly and bulky, and do not lend themselves to use with other vision correcting lenses (29). Perhaps, instead of enforcing the use of aids, the aid could be suggested, and teachers and the individual learner could collaborate to decide if the aids help or hinder. Keeping in mind the variability of the colour spectrum in each person with CCVD, it is prudent to appreciate that one size may not fit all. Without the dominance of colour, all the other attributes are enhanced (surface, texture, transparency). This could be an advantage – would doctors with CCVD be better placed to pick up subtle differences between normal and abnormal? We don’t know. Who are we to decide? Who is to say that, when colour-normal providers make mistakes, it is nothing to do with the fact that their colour dominance distracts them from seeing other important things? It is worth reproducing here what some of our respondents said:

“Some doctors are careless even if they can see colours. I would prefer a thorough doctor with CCVD to a physician who takes me for granted.”

“Color perception cannot be the only criteria to determine capability of a doctor.”

“Have undergone umpteen diagnostic tests and radiological investigations since birth – and am still alive. We never tried to find out who all were color blind – possibly there were a few.”

The voices of doctors with CCVD

The only way to answer these questions is to study more doctors with CCVD – the best way to do that is by having more doctors with CCVD across the board in the healthcare field and by removing fear of stigma so that they share their experiences. If our participants are to be believed, their colleagues with CCVD posed no risk to patients. It would be best if we could hear from more doctors who are colour blind. They are welcome to share openly; however, they might inadvertently expose themselves to stigma and to a possible witch-hunt where they could selectively be asked to prove their competency. Perhaps an anonymous study can be designed to figure this out. Certainly, as mentioned earlier, we had hoped to hear from more doctors with CCVD, but that did not happen for the reasons mentioned previously. We request healthcare providers with CCVD to reach out to us.

Strengths and limitations of the study

The sample size of this study is large enough to warrant generalisation of its results across the country. Participants had enough post-specialisation experience to make their responses valuable. Even though only a few of the participants themselves had CCVD, we had representation from PP, as also from MM and SS specialties, allowing a glimpse of how each broad group viewed the dilemma of CCVD in medicine. On the flip side, this was an online, anonymous survey and may not have been able to capture as much information as a face-to-face interview may have done. A focus group discussion might have helped determine lived experiences, experiences with ableist microaggression from peers and faculty, and adjustments made over time by participants with CCVD. Some participants may not have had enough knowledge about CCVD and may have given generic responses; however, the responses also indicated the reverse – that a number of respondents were aware of the nuances of CVD. Being anonymous, we have no way to reach out to the participants with CCVD for their degree of deficiency or for follow-up discussions; however, we are hopeful that those who wish to share their experiences and their learning and coping mechanisms will reach out to us so as to settle this matter once and for all

Conclusions

Our respondents varied in their opinions with respect to people with CCVD in medicine; the insights they provided were useful in formulating an advisory. For the time being, until we learn more about how providers’ CCVD impacts patient care in each specialty, CCVD should not be a barrier to practising in any specialty of medicine. Rather than blocking medical students from joining a postgraduate course that they are otherwise eligible for, they could be encouraged, while still undergraduates, to explore their particular grade of CCVD for any difficulty it could cause during practice. They need to be open to sharing, and teachers and peers should be open to supporting them and providing reasonable accommodation so that they find ways to compensate for their particular colour spectrum. Learning this in a supported environment can prepare them for safe care in real life when they work with patients. This is the responsibility of the faculty departments, institutions, regulatory bodies, and governments, keeping in mind the rights of people with CCVD to practise medicine within the realms of patient safety. Depending on how confident they feel after training, they should make informed decisions about which specialty they can be most comfortable practising safely in. There is a need to train faculty in the tenets of reasonable accommodation and also to provide opportunities to undergraduate learners with CCVD to shadow physicians in the specialty of their choice before making the decision to train in it.

Funding support: none.

Conflict of interest: Dr Upreet Dhaliwal has first degree relatives with CCVD. They are not medical practitioners. Their non-medical career choices, in their own words, were not influenced by the CCVD, but were dictated by their areas of interest.
