WHAT ARE SOME POTENTIAL RISKS AND CHALLENGES THAT COULD ARISE WHEN IMPLEMENTING AI IN HEALTHCARE

Leave a reply

As with the introduction of any new technology, implementing artificial intelligence in healthcare comes with certain risks and challenges that must be carefully considered and addressed. Some of the major risks and challenges that could arise include:

Privacy and security concerns – One of the biggest risks is around privacy and security of patients’ sensitive health information. As AI systems are collecting, analyzing, and having access to massive amounts of people’s personal health records, images, genetic data, there are risks of that data being stolen, hacked, or inappropriately accessed in some way. Strict privacy and security protocols would need to be put in place and constantly improved to mitigate these risks as threats evolve over time. Consent and transparency around how patient data is being used would also need to be thoroughly addressed.

Bias and unfairness – There is a risk that biases in the data used to train AI systems could negatively impact certain groups and lead to unfair, inappropriate, or inaccurate decisions. For example, if most of the data comes from one demographic group, the systems may not perform as well on other groups that were underrepresented in the training data. Careful consideration of issues like fairness, accountability, and transparency would need to be factored into system development, testing, and use. Oversight mechanisms may also need to built-in to identify and address harmful biases.

Clinical validity and safety – Before being implemented widely for clinical use, it will need to be thoroughly determined through testing and regulatory review that AI tools are in fact clinically valid and deliver the promised benefits without causing patient harm or introducing new safety issues. Clinical effectiveness for the intended uses and patient populations would need to be proven through well-designed validation studies before depending on these systems for high-risk medical decisions. Unexpected or emergent behaviors of AI especially in complex clinical scenarios could pose risks that are difficult to anticipate in advance.

Overreliance on and trust in technology – As with any automation, there is a risk that clinicians and patients could become overly reliant on AI tools and trust them more than is appropriate or advisable given their actual capabilities and limitations. Proper integration into clinical workflow and oversight would need to ensure humans still maintain appropriate discretion and judgment. Clinicians will need education around meaningful use of these technologies. Patients could also develop unreasonable trust or expectations of what these systems can and cannot do which could impact consent and decisions about care.

Job disruption – There are concerns that widespread use of AI for administrative tasks like typing notes or answering routine clinical questions could significantly disrupt some healthcare jobs and professions. This could particularly impact low and middle-skilled workers like medical transcriptionists or call center operators. On the other hand, new high-skilled jobs focused more on human-AI collaboration may emerge. Health systems, training programs, and workers would need support navigating these changes to ensure a just transition.

Accessibility – For AI healthcare technologies to be successfully adopted, implemented, and have their intended benefits realized, they must be highly accessible and useable by both clinical staff and diverse patient populations. This means considering factors like user interface design, multiple language support, accommodations for disabilities like impaired vision or mobility, health literacy of patients, digital access and divide issues. Without proper attention to human factors and inclusive design, many people risk being left behind or facing new challenges in accessing and benefitting from care.

Lack of interoperability – For AI systems developed by different vendors to be effectively integrated into healthcare delivery, they will need to seamlessly interoperate with each other as well as existing clinical IT systems for things like EHRs, imaging, billing and so on. Adopting common data standards, application programming interfaces and approaches to semantic interoperability between systems will be important to overcome this challenge and avoid data and technology silos that limit usefulness.

High costs – Initial investment and ongoing costs of developing, validating, deploying and maintaining advanced AI technologies may be prohibitive for some providers, particularly those in underserved areas or serving low-income populations. Public-private partnerships and programs would likely need to help expand access. Reimbursement models by payers will also need to incentivize appropriate clinical use of these tools to maximize their benefits and cost-effectiveness.

For AI to reach its potential to transform healthcare for the better it will be critical to have thoughtful consideration, planning and policies around privacy, safety, oversight, fairness, accessibility, usability, costs and other implementation challenges throughout the process from research to real-world use. With diligence, these risks can be mitigated and AI’s arrival in medicine can truly empower both patients and providers. But the challenges above require a thoughtful, evidence-based and multidisciplinary approach to ensure its promise translates into real progress.

WHAT ARE SOME POTENTIAL LIMITATIONS OF USING SELF REPORT MEASURES IN THIS STUDY

Leave a reply

One of the biggest potential limitations of self-report measures is biases related to social desirability and impression management. There is a risk that participants may not report private or sensitive information accurately because they want to present themselves in a favorable light or avoid embarrassment. For example, if a study is examining symptoms of depression, participants may under-report how frequently they experience certain feelings or behaviors because admitting to them would make them feel badly about themselves. This type of bias can threaten the validity of conclusions drawn from the data.

Another limitation is recall bias, or errors in a person’s memory of past events, behaviors, or feelings. Many self-report measures ask participants to reflect on periods of time in the past, sometimes going back years. Human memory is fallible and can be inaccurate or incomplete. For events farther back in time, details may be forgotten or reconstructed differently than how they actually occurred. This is a particular problem for retrospective self-reports but can also influence current self-reports if questions require remembering specific instances rather than overall frequencies. Recall bias introduces noise and potential inaccuracy into the data.

Response biases related to self-presentation are not the only potential for socially desirable responding. There is also a risk of participants wanting to satisfy the researcher or meet perceived demands of the study. They may provide answers they think the experimenter wants to hear or will make the study turn out as expected, rather than answers that fully reflect their genuine thoughts, feelings, and experiences. This threatens the validity of inferences about psychologically meaningful constructs if responses are skewed by a desire to please rather than a candid report of subjective experience.

Self-report measures also rely on the assumption that individuals have reliable insight into their own thoughts, behaviors, traits, and other private psychological experiences. There are many reasons why a person’s self-perceptions may not correspond perfectly with reality or with objective behavioral observations. People are not always fully self-aware or capable of accurate self-analysis and self-diagnosis. Their self-views can be biased by numerous cognitive and emotional factors like self-serving biases, selective attention and memory, projection, denial and reaction formation, and more. Relying only on self-report removes the capability for cross-validation against more objective measures or reports from knowledgeable others.

Practical difficulties inherent to the self-report format pose additional limitations. Ensuring participants interpret vague or complex questions as intended can be challenging without opportunity for clarification or explanation by the researcher. Response scales may not provide optimal sensitivity and precision for measuring psychological constructs. Question order effects, question wording choices, and other superficial qualities of the measure itself can unduly influence responses independent of the intended latent variables. And low literacy levels, language barriers, or limited attention and motivation in some participants may compromise reliability and validity if questions are misunderstood.

An issue that affects not just the accuracy but also the generalizability of self-report findings is that the psychological experience of completing questionnaires may itself shape responses in unforeseen ways. The act of self-reflection and item consideration activates certain cognitive and affective processes that do not mirror real-world behavior. And researchers cannot be sure whether measured constructs are elicited temporarily within the artificial context of research participation or indicative of patterns that generalize to daily life outside the lab. Ecological validity is challenging to establish for self-report data.

Practical difficulties also emerge from logistical demands of obtaining and interpreting self-report data. Large sample sizes are usually required to achieve sufficient statistical power given the noisiness of self-report. But recruitment and full participation across numerous multi-item measures poses challenges for both researchers and subjects. Substantial time, resources and effort are required on the part of researchers to develop quality measures, administer them properly, screen responses for quality, handle missing data, and quantitatively reduce information from numerous items into interpretable scores on underlying dimensions.

Some key limitations of self-report methods include issues with biases that threaten validity like social desirability, recall bias, and response bias to please researchers. Additional difficulties emerge from lack of objective behavioral measures for comparison or validation, imperfect self-awareness and insight, susceptibility to superficial qualities and context of the measures themselves, questionable generalizability beyond research contexts, and substantial logistical and resource demands for quality data collection and analysis. Many of these are challenging, though not impossible, to control for or address through research design features and statistical methods. Researchers using self-report must carefully consider these issues and their potential impact on drawing sound scientific conclusions from the results obtained.

WHAT ARE SOME POTENTIAL JOB LOSSES THAT COULD OCCUR WITH THE WIDESPREAD ADOPTION OF SELF DRIVING CARS

Leave a reply

The widespread adoption of self-driving vehicles has the potential to significantly impact many existing jobs. One of the largest and most obvious job categories that could see major losses is commercial drivers such as taxi drivers, ride-hailing drivers such as Uber and Lyft operators, truck drivers, and bus drivers. According to estimates from the U.S. Bureau of Labor Statistics, there are over 3.5 million Americans employed as drivers of taxi cabs and ride-hailing vehicles, heavy and tractor-trailer truck drivers, and bus drivers. With self-driving vehicles able to operate without a human driver, the need for people to operate vehicles for a living would greatly diminish.

While self-driving trucks may still require drivers as attendants initially, the role would be more supervisory than operational driving the vehicle. Over time, the job functions of commercial drivers could be eliminated altogether as technology advances. This would result in massive job losses across these commercial driving industries that currently employ millions. Commercial driving also has many ancillary jobs associated with it such as truck stop employees, repair shop workers, weight station attendants, and others that could see reduced demand. The impact would ripple through local economies that rely heavily on commercial transportation.

In addition to commercial drivers, many automotive industry jobs could be affected. Mechanics focused on repairing and maintaining human-operated vehicles may see reduced demand for their services. As self-driving vehicles rely more on software, communication systems, and sensor technologies rather than mechanical components, the needs of vehicles will change. While new technical mechanic and repair jobs may emerge to service autonomous technologies, many existing mechanic specializations could become obsolete. Manufacturing line workers building vehicles may also face risks. As vehicles require fewer human-centric components and more computers and automation, production facilities would likely require fewer workers and adopt more industrial robotics.

Complementing the mechanical and manufacturing implications are a variety of jobs in supporting industries. From vendors that serve gas stations and truck stops to motels along highways that rely on commercial driver customers, many local businesses could take an economic hit from less vehicle traffic operated by humans. Roadside assistance workers like tow truck drivers may have lower call volumes as self-driving vehicles have fewer accidents and need less aid with tasks like jump starts. Even industries like motor vehicle parts suppliers, car washes, and parking facilities could see their customer base erode over time with autonomous vehicles that require less human oversight and operation.

Insurance and finance sector jobs linked to vehicle ownership may also see reallocation. Roles associated with insuring human drivers against issues like accidents and liabilities would logically decline if robot-driven cars cause drastically fewer crashes. Auto insurance models and underwriting specialists may need to shift focus. On the lending side, banks and finance companies that currently provide loans and financing packages for vehicle purchases may originate fewer new loans as shared mobility further reduces private car ownership. Related customer service and debt collection roles could consequently contract. Real estate could additionally feel impacts, as autonomous vehicles may reduce demand for non-residential developments centered around human transportation needs from gas stations to parking decks.

While the nature of many transportation planning, urban design, traffic engineering and government regulatory jobs would transition alongside autonomous vehicle integration, overall staffing levels in these fields may not necessarily decrease. Without intervention, job losses across whole sectors like commercial driving could number in the millions. Proactive workforce retraining programs and policy will be crucial to help displaced workers transition skills and find new occupations. There would surely be many new types of jobs created to develop, deploy and maintain autonomous vehicle systems, but the costs of lost jobs may unfortunately outweigh the benefits for some time without strategies to support workers through change. Widespread autonomous vehicle adoption holds potential economic gains, but also significant risks to employment that responsible leaders must address proactively to manage impacts. The changes will be massive, and managing this transition effectively will be one of the great challenges in developing self-driving technology for the benefit of society.
