As a future advanced practice registered nurse specializing in PMHNP it is important to understand the magnitude of diagnostic and medicalerrors that are made. Cantey (2020) noted that Recent research has identified several dimensions in which a diagnostic error can occur, including patient-provider encounter, interpretation of diagnostic tests, follow-up, communication and coordination of specialist referrals, and patient’s behavior to recommended treatment (p. 582). In the provider role it is important to always stay up to date with ongoing changes in healthcare. Whether it be regulations, screenings, evidence-based practice guidelines, and CDC guidelines. In the role of a PMHNP I can take part in decreasing diagnostic errors by making sure me and my staff are up to date with the DSM-5. The last published DSM-5 was in 2013 sense then there had been updates. These updates include new references, updates to the ICD-10-CM codes and clarification to diagnostic criteria. Therefore, reviewing the DSM-5-TR and having staff review such changes is important to preventing diagnostic errors. Also, as a future APRN it is vital to establish great rapport with patients and other providers. This ensures that we establish the best treatment plan for our patients and provide patients with additional support from other professionals. Cantey (2020) noted that The large majority of diagnostic errors are not due to knowledge deficits but are related to cognitive biases, failed perception, and failed heuristics (i.e., mental shortcuts) (p. 582). According to Cantey there have been several procedures that were conducted by using cognitive debiasing to reduce diagnostic errors with nurse practitioner students. Cantey (2020) noted that Understanding the causes of errors can help nurse practitioners develop increased awareness of their own biases and therefore reduce the influences on clinical reasoning. Experts acknowledge that there is not a one size fits all strategy for debiasing, but with increased awareness and development of new strategies, the cognitive process can be improved (p. 583). I do agree that when NP’s or physicians understand this concept this can lead to better treatment for patients and will decrease malpractice suits.
