Blockchain Primer
Published in Salvatore Volpe, Health Informatics, 2022
Full nodes are essential to the overall security and validity of the blockchain network and have two responsibilities that differentiate them from other types of nodes. A full node inspects and validates each digital signature in every transaction to authenticate the transaction. A digital signature is usually the private key the sender of the transaction uses to sign each transaction. Full nodes are not miners, which is a common misconception.

One of the main aims of RT object visualisation is for the clinical oncologist to review plans, dose and images and give their approval to the plan that has been produced. Once treatment has started, the clinical oncologist may view the portal images in conjunction with planning reference images and give their approval for treatment to continue. The approval status of radiotherapy objects is very important and is included within the DICOM standard. It should be possible for clinicians to approve objects with an electronic signature and for this approval status to be clearly indicated.

An application to cremate is done by a relative or executor filling in the prescribed form. This requires him/her to confirm that the deceased expressed no wish not to be cremated. Following this, under normal circumstances, signatures are required by three registered medical practitioners; all three need to identify and examine the body (see Chapter 32). The three must be: a doctor who attended the deceased during their last illnessa second independent doctor with no close relationship to the first doctora third doctor known as the Medical Referee of the Crematorium.

Successful enrollment of a patient for PAP services often requires involvement from several different players—the 4Ps: Patient, Physician, Pharmaceutical Company, and Pharmacy (Figure 1). Most programs require a healthcare provider, patient, or both to complete an application form; a doctor’s signature is almost always required (17). The majority of programs require patients to submit a prescription, ICD code or physician license number as part of the application process (2), therefore all should be included in the application to prevent delays. Healthcare providers should clearly document the need for the prescription, including what medications have been tried/failed and why alternative medications are not suitable or are contraindicated (17). To streamline the process, a prescription coordinator can be added to the team. Having a medical assistant or other dedicated office staff member can help to further expedite the process.
Ethical Challenges in Advance Care Planning During the COVID-19 Pandemic

Advance care planning has been promoted as a part of routine care with family practitioners for many years but may be even more valuable now for those persons at higher risk of severe illness from COVID-19. The ideal setting for advance care planning conversations during the COVID-19 pandemic may be at home during a telehealth visit with one’s physician. Here, there would be an opportunity for patients to ask the physician any questions they might have about the documentation. Depending on the jurisdiction, the patient and physician could also work together to bring in additional people electronically to witness the patient’s signature without relying on a notary. Additionally, patients could discuss their choices with family. This would allow time for patients to share their reflections and inform family members of their wishes prior to any acute event. Residents of nursing homes and assisted-living facilities, and healthcare workers with high exposure risks ought to be a primary target for this community-centered intervention (Curtis 2020).
Public and private surgeon attitude towards informed consent
Published in Alexandria Journal of Medicine, 2018
A considerable number of medical researches has been conducted recently on the consent process. Most of them focused on patients – doctors' attitudes towards consent.13,14 The notion of informed consent is usually more related to surgical specialties than other clinical specialties because patient should decide to participate into surgery and permissiveness for surgeons to operate on them.15 Advanced surgery has been practiced for long time in state of Kuwait. Yet, to our knowledge, no studies have been conducted to examine surgeons' attitudes towards informed consent in Kuwait. Kuwait has introduced compulsory medical consent to be given by patients before any procedure. According to the this document, doctors should inform patients about medical protocols and options available for the case before getting patient signature prior to any medical procedure. Doctors also should provide all information, including possible risks. This would be mandatory in public as well as private hospitals and clinics.16 This has been documented by Ministerial decree No. 307/2015.17
