Ethics and Patient Safety

A tertiary care hospital recently experienced a near-miss event where a patient almost received a lethal dose of concentrated potassium chloride due to an automated dispensing cabinet (ADC) stocking error. In response, the hospital administration decides to proactively evaluate the new ADC system workflow being implemented in the intensive care unit before it goes live. The quality improvement committee initiates a Failure Mode and Effects Analysis (FMEA). Arrange the following steps of the FMEA process in the correct chronological sequence.

A 48-year-old woman is admitted to the intensive care unit following a severe aneurysmal subarachnoid hemorrhage. She is currently intubated, comatose, and determined by the medical team to lack decision-making capacity. Her prognosis for meaningful neurologic recovery is exceptionally poor. The clinical team is considering transitioning to comfort-focused care, but a severe conflict arises among her visitors at the bedside. Her legally married husband, from whom she has been informally separated for three months, wishes to withdraw life support. Her 25-year-old daughter insists on continuing all aggressive medical interventions. The patient's mother is also present and requests that a tracheostomy be performed. Her older brother demands an immediate ethics committee consult to resolve the dispute. Additionally, a close friend arrives and produces a verified, signed legal document from two years ago naming the friend as the patient's designated healthcare proxy. The patient does not have a living will.

Arrange the following individuals in the correct order of their legal priority to act as the primary surrogate decision-maker for this patient, from highest (most authoritative) to lowest.

The leadership at an academic medical center is preparing to integrate a novel artificial intelligence-driven diagnostic triage software in the emergency department. To proactively identify and mitigate vulnerabilities before the software goes live, the administration initiates a Failure Mode and Effects Analysis (FMEA).

Arrange the following steps of the Failure Mode and Effects Analysis (FMEA) in the correct procedural sequence.

A 55-year-old man in the intensive care unit is receiving treatment for severe community-acquired pneumonia. The nurse retrieves a premixed medication bag from the automated dispensing cabinet and initiates an intravenous infusion. Twenty minutes later, the patient develops profound hypotension, bradycardia, and a decreased level of consciousness. A review of the medication bag reveals that the patient inadvertently received an infusion of dexmedetomidine instead of the prescribed ceftriaxone. The infusion is stopped, and the patient is successfully resuscitated with intravenous fluids and supportive care. The hospital risk management team notes that the two medications are supplied in identically sized foil pouches with similar barcode placements. Which of the following is the most appropriate next step in the management of this adverse event?

A hospital network has recently expanded its Quality and Safety Department to standardize the approach to medical errors and process improvements. The new director is conducting a workshop for department chairs on the appropriate utilization of various quality improvement and patient safety frameworks. Match each clinical safety scenario or definition with the most appropriate patient safety methodology.

A $72$-year-old woman is admitted to the hospital for a total knee arthroplasty. On postoperative day $2$, she is found unresponsive with a respiratory rate of $6$/min and pinpoint pupils. She is successfully resuscitated with intravenous naloxone and transferred to the intensive care unit. A review of the electronic health record and the patient's medical devices reveals that she was receiving continuous intravenous hydromorphone via a patient-controlled analgesia pump. The nurse had inadvertently programmed the basal rate to $2.0$ mg/hr instead of the intended $0.2$ mg/hr. The hospital's patient safety committee convenes a multidisciplinary team to perform a root cause analysis. The team completes the initial phase of the investigation, which includes securing the pump, reviewing the medical record, and interviewing all involved staff to establish a precise timeline of events.

Which of the following is the most appropriate next step for the patient safety committee?

A 75-year-old man with early-stage Alzheimer disease is evaluated in the outpatient vascular surgery clinic for a recently discovered 6.5-cm abdominal aortic aneurysm. The surgeon explains that without repair, there is a high risk of fatal rupture. The patient correctly restates his diagnosis, articulates the risks of both surgical intervention and non-operative management, and states, "I have lived a full life and I do not want to spend my remaining days recovering from a major operation. I decline the surgery." Later that day, the patient's son, who is the legally designated healthcare proxy, contacts the clinic. The son demands that the surgery be scheduled immediately, arguing that his father's dementia diagnosis renders him incapable of making this life-or-death decision. The physician has already conducted a structured capacity assessment and determined that the patient fully possesses decision-making capacity for this specific medical decision. Which of the following is the most appropriate next step in management?

The quality and safety committee at a regional medical center is analyzing a recent cluster of medication errors in the pediatric wing. Over the past two months, several nurses inadvertently administered adult-dose acetaminophen suppositories to infants, though no severe hepatotoxicity occurred. A multidisciplinary task force is formed to evaluate these incidents. During their first meeting, members brainstorm numerous contributing factors, such as identical packaging for different medication strengths, frequent alarms causing distraction, staffing shortages on weekends, and an unintuitive electronic prescribing interface. The committee coordinator suggests mapping out these identified issues into a specific visual format, grouping them under standardized headings like 'Environment,' 'Equipment,' 'People,' and 'Processes,' to better understand how they interrelate to cause the adverse events. Which of the following quality improvement tools is being described?

A 77-year-old man with advanced idiopathic pulmonary fibrosis is transported to the emergency department due to acute-on-chronic hypoxemic respiratory failure. Upon arrival, the patient is lethargic, intermittently delirious, and unable to communicate coherently. The attending physician determines he currently lacks decision-making capacity. The patient is exhibiting severe respiratory distress, and the clinical team recommends emergent intubation.

The patient's legally designated healthcare proxy—his long-term domestic partner—is present at the bedside. Shortly after, the patient's adult son arrives and presents a formalized living will signed by the patient four years ago. The document clearly states a refusal of mechanical ventilation in the setting of irreversible lung disease. The son insists the team follow the written document and provide comfort care only. The domestic partner acknowledges the document but reports that three days ago, during a period of lucidity, the patient explicitly stated he wanted "everything done, including a breathing tube," so he could survive long enough to attend his granddaughter's wedding next month. The son objects, arguing that a written, notarized document cannot be legally overridden by unverified oral claims.

Which of the following is the most appropriate next step in the management of this patient?

A 72-year-old man with end-stage chronic obstructive pulmonary disease is brought to the emergency department for severe, progressive shortness of breath over the past 24 hours. On arrival, he is lethargic, oriented only to person, and unable to engage in medical discussions. His respiratory rate is 32/min, and oxygen saturation is 74% on a non-rebreather mask. Arterial blood gas analysis reveals a pH of 7.21, PCO2 of 85 mm Hg, and PO2 of 45 mm Hg. The electronic medical record contains a valid advance directive (living will) executed 8 months ago, explicitly stating that he refuses endotracheal intubation and mechanical ventilation under any circumstances. His wife, who is legally designated as his healthcare proxy, arrives shortly after. She is visibly distressed and states, "I know what his living will says, but he has survived bad exacerbations before. I want him on a breathing machine right now. As his proxy, my decision is final." Which of the following is the most appropriate next step in management?

For each patient lacking decision-making capacity described below, identify the primary legal or ethical framework that dictates how their medical care should be directed.

An elderly patient with type 2 diabetes experiences a severe hypoglycemic seizure on the medical ward after a nurse inadvertently programs an intravenous insulin pump to deliver ten times the intended hourly rate. The patient requires emergency administration of dextrose. Arrange the following actions regarding the management, disclosure, and investigation of this medical error in the most appropriate chronological sequence.

Match each clinical scenario or surrogate decision-making description regarding end-of-life care to its corresponding legal instrument or ethical standard.

A 62-year-old man is admitted to the hospital at night with a small bowel obstruction. He has a fever, tachycardia, and localized abdominal guarding. The night-float resident decides to manage the patient conservatively with nasogastric decompression and intravenous fluids. The next morning, the day-shift resident assumes care, recognizes the signs of bowel ischemia, and immediately alerts the attending surgeon. The patient undergoes an emergency laparotomy, which reveals a strangulated bowel loop requiring resection.

Postoperatively, while the patient is intubated in the intensive care unit, the patient's legally appointed healthcare proxy asks the day-shift resident, "Why wasn't the surgery done last night? Could the bowel resection have been avoided?" The night-float resident, who is also present, privately asks the day-shift resident not to mention the delayed diagnosis to protect their career.

Which of the following is the most appropriate next step for the day-shift resident?

Dr. Chen, a physician in a large multispecialty clinic, observes that a peer colleague in her department consistently orders an extensive, unnecessary panel of proprietary laboratory tests for every healthy patient undergoing a routine annual physical. Dr. Chen discovers that the colleague has a financial stake in the laboratory company performing these tests, a conflict of interest that is not disclosed to the patients. Because there is no immediate medical danger to the patients, arrange the following actions in the ethically appropriate sequence Dr. Chen should take to address this professionalism breach.

A 58-year-old woman with widely metastatic breast cancer is admitted to the palliative care unit for management of intractable bone pain and severe dyspnea. She is intermittently confused, deeply somnolent, and currently lacks the capacity to make complex medical decisions. Her medical prognosis is poor, with an estimated survival of days to weeks. Two years ago, while fully competent, the patient executed a legal advance directive designating her longtime friend as her healthcare proxy. The document explicitly outlines her preference for comprehensive symptom management aimed at comfort, even if such measures inadvertently shorten her life. The designated proxy requests the initiation of a continuous intravenous morphine infusion to alleviate her distress. The patient's sister, who has been estranged for a decade but recently arrived at the hospital, vehemently opposes the infusion, demanding that it be withheld out of fear it will cause a fatal respiratory arrest. Which of the following is the most appropriate next step in management?

A 45-year-old man is brought to the emergency department after a severe motor vehicle collision. He is intubated, comatose, and lacks decision-making capacity. The trauma surgery team determines he requires an emergent decompressive craniectomy for a rapidly expanding epidural hematoma. The patient has no written advance directives and has not legally designated a healthcare proxy. Several family members arrive at the hospital and express differing opinions on whether to proceed with the surgery. According to the standard legal hierarchy of surrogate decision-makers, arrange the following family members in order of their priority to make medical decisions on behalf of the patient, from highest priority (first) to lowest priority (last).

A hospital quality improvement committee is reviewing various metrics to evaluate patient safety initiatives. Match each clinical metric described below to its appropriate quality measure classification.

A hospital's quality improvement committee identifies a rising incidence of central line-associated bloodstream infections (CLABSIs) across its intensive care units over the past quarter. To address this issue, the committee decides to employ the Plan-Do-Study-Act (PDSA) quality improvement model to implement a standardized daily chlorhexidine bathing protocol.

Arrange the following steps of this quality improvement initiative in the correct chronological sequence according to the PDSA cycle.

For each of the following scenarios involving end-of-life care or surrogate decision-making, identify the corresponding ethical principle, legal standard, or directive that dictates or justifies the medical approach.
