The Efficacy Of Dermoscopy: Part 2

by The DermEngine Team on Mar 19, 2018

In The Efficacy Of Dermoscopy: Part 1,  we investigated the accuracy of diagnoses with the use of digital dermoscopes like MoleScope II in contrast to without the use of such a device. From here, cost-effectiveness was briefly speculated with the conclusion that further research was necessary. Part two will provide a more comprehensive look at this second point while discussing potential methods for improvement of care in the field of dermatology.

What About Cost-Effectiveness?

Although it can be determined that the use of a digital dermoscope increases diagnostic accuracy, studies pointing to cost-effectiveness of the device are not as conclusive.  For example, one study found that the diagnosis of melanoma by dermatoscopy-trained dermatologists resulted in an increase of quality-adjusted years of life (decrease in morbidity and/or mortality) in addition to a reduction in costs.1

Supporting these conclusions, a group of researchers in Deutschland set out to determine the diagnostic accuracy and cost efficacy of dermoscopy in primary care. The study found that the probability of a correct diagnosis was approximately 1.25 times higher when using a dermatoscope and appeared to be cost effective. The study goes on to state that although no tool can (yet) allow for a 100% accurate diagnosis rate, they recommended the use of a digital dermoscope for all dermatologists.2
MoleScope II - Advanced Dermatoscopes

In contrast, another study found that due to an absence of evidence it was inconclusive in determining the reality or rate of cost-effectiveness from the use of dermatoscopes in the practice of dermatologists. However, it is important to note that in contrast to the findings above, this study went on to conclude that “no conclusions can be drawn on the impact of dermoscopy on clinical outcomes [or] diagnostic accuracy in detecting non-melanoma skin cancers”.3

Areas For Improvement

Due to the evidence favoring the use of dermoscopy for diagnosis accuracy and cost-effectiveness, it creates the question of what else can be done to enhance these traits? Although an open-ended question, there are many tools and software specifically designed to enhance dermatoscopy (especially in the areas of support and streamlining workflows).

Challenges that these technologies could improve include:

  • Dermatologist shortage/wait times: Studies show that countries like the United States are experiencing an extreme dermatologist shortage, with some patients being forced to wait upwards of six months. By utilizing teledermoscopy software, professionals can avoid unnecessary in-clinic visits, organize their workload, and remain accessible to a wider range of patients.
  • Physical paperwork overload: Research demonstrates that physicians spend nearly 50% of their time on desk/paper work. By utilizing a dermatology EMR software that stores all of their patient data in a centralized location while providing valuable insights for business intelligence, experts can remain organized and focus on their patients while enhancing their practice.
  • Manual imaging: In many cases, patients (especially those with a history or high risk of developing skin cancer) may have a large number of spots which prove daunting and time-consuming to image, document and organized (especially for follow up appointments). By using intelligent total body photography software, dermatologists can utilize mole mapping technology to automatically transfer a patient's spots to a 3D Body Map for optimized imaging.
  • Challenging cases: In many scenarios, physicians and dermatologists alike could use support from their colleague or an expert to support their clinical decisions. Smart tools like Visual Search are powered by machine learning to provide visually similar images to your submitted case while providing valuable insights into potential diagnoses and risk of malignancy. This is an excellent clinical decision support tool  and learning resource for the continued education of experts.

Doctors discussing medical plan

Examples such as these demonstrate that optimizing dermatology diagnosis accuracy and cost-effectiveness is not limited to the dermoscope itself. Rather, there are a wide variety of opportunities to optimize the practice of medical professionals. Intelligent dermatology software like DermEngine provide advanced solutions to these challenges in an all-in-one advanced solution, with the potential to enhance cost effectiveness, workflows, organization, patient relationships, and accessibility to medical professionals.


In conclusion, research (mostly) suggests that the mobile dermoscope is indeed a cost-effective tool for dermatologists to use. Studies demonstrate that in addition to enhancing diagnostic accuracy and early detection (thus lowering costs associated with expensive late-stage treatments for conditions such as melanoma). Although this two-part article has concluded that advanced dermoscopy is an essential component to optimizing the practice of dermatologists, it will be important to monitor where technologies (particularly in artificial intelligence (AI) will lead the dermatology industry in the future.
