Arizona — Hospital Regulatory & Mandatory Reporting Guide

Arizona — Hospital Regulatory & Mandatory Reporting Guide

Arizona is a significant hospital-regulation jurisdiction because serious hospital liability is not assessed through bedside conduct alone. Arizona hospitals operate under a detailed licensing code enforced by the Arizona Department of Health Services, and that framework directly regulates administration, quality management, discharge planning, transfer, patient rights, medical records, emergency services, infection control, and disaster management. In practical litigation terms, that means a serious Arizona hospital case is rarely just a negligence case involving one provider. It is often an institutional quality-management, discharge-integrity, infection-control, emergency-response, and documentation-credibility case.

That distinction matters because Arizona does not rely primarily on a single headline hospital adverse-event statute in the same way some states do. Instead, Arizona creates institutional accountability by requiring hospitals to maintain documented administrative and quality systems, protect patient rights, create and preserve defensible records, manage discharge and transfer safely, maintain emergency capabilities, and establish infection-control systems that prevent, identify, and document infections and communicable diseases. Where the event also involves infectious disease, cluster conditions, or outbreak concerns, Arizona’s separate communicable-disease reporting rules create a second public-health-facing chronology.

As a result, strong Arizona hospital matters are often best framed not as simple malpractice cases but as institutional systems and reporting-integrity cases. The key questions usually become when the hospital recognized the seriousness of the occurrence, whether it moved through its quality-management and administrative pathways appropriately, whether discharge or transfer handling was safe and justified, whether infection-control and public-health duties were triggered, and whether the chart, the hospital’s internal response, and any regulator-facing conduct remain aligned.

Quick Authority Snapshot

Primary State Regulatory Authority

The Arizona Department of Health Services (ADHS), which licenses hospitals and enforces the Arizona health care institution licensing rules in 9 A.A.C. 10.

Core Hospital Regulatory Framework

Arizona hospitals are governed principally by 9 A.A.C. 10, Article 2, which includes rules on administration, quality management, discharge planning, transfer, patient rights, medical records, emergency services, infection control, and disaster management.

Discharge and Transfer Overlay

Arizona specifically regulates discharge planning and discharge under R9-10-209 and transfer under R9-10-211. This makes continuity-of-care, handoff, and premature discharge issues especially important in hospital litigation.

Records and Patient Rights Overlay

Arizona separately regulates patient rights under R9-10-212 and medical records under R9-10-213. That means chart instability, weak patient communication, consent-sensitive disputes, and rights-based failures carry independent institutional significance.

Infection / Public Health Overlay

Arizona regulates hospital infection control under R9-10-230 and separately requires reporting of communicable disease cases, suspect cases, occurrences, and outbreaks under 9 A.A.C. 6. Outbreak-reporting tools used by ADHS direct immediate reporting by administrators of health care institutions.

Attorney Takeaway

In Arizona, case value often turns on whether the hospital recognized the event as institutionally significant, activated quality, discharge, transfer, infection-control, and emergency systems appropriately, preserved a stable record, and kept its clinical and regulator-facing narratives consistent.

Statutory & Regulatory Architecture

9 A.A.C. 10, Article 2 — Arizona Hospital Licensure Structure

Arizona’s hospital framework is significant because it regulates the hospital as an organized institution rather than merely as a place where clinicians practice. Article 2 establishes formal requirements for hospital administration, quality systems, patient protections, records, emergency services, infection control, and disaster management. In litigation, this means a serious Arizona hospital event can be measured not only against professional standard-of-care testimony, but against whether the hospital’s licensed systems functioned in the way Arizona expects.

R9-10-203 — Administration

Arizona’s administration rule is important because it requires a hospital to function through documented policies, procedures, and accountable administrative oversight. In practice, this gives institutional significance to communication failures, policy drift, weak supervision, and fragmented response to a serious event. Many high-value cases are not driven by one bedside mistake alone; they are driven by failure of organized hospital administration when danger emerged.

R9-10-204 — Quality Management

Arizona’s quality-management rule is one of the strongest institutional-liability anchors in the state. A hospital must maintain a documented quality-management process. This matters because serious events should be analyzed not only as isolated injuries, but as tests of whether the hospital had a functioning quality structure capable of identifying, evaluating, and responding to the kind of failure that occurred. In litigation, that often becomes a major dividing line between provider-only fault and broader institutional fault.

R9-10-209 — Discharge Planning; Discharge

Arizona’s express regulation of discharge planning gives continuity-of-care cases unusual strength. When a patient is discharged prematurely, discharged without stable follow-up arrangements, sent out despite unresolved deterioration, or discharged with poor medication or return-precaution instructions, the issue is not merely whether a physician made a bad call. It is whether the hospital’s regulated discharge system functioned safely and in a manner consistent with Arizona law.

R9-10-211 — Transfer

Transfer failures are also especially important in Arizona because transfer is separately regulated. In practical litigation terms, incomplete receiving-facility communication, weak transport decision-making, inadequate stabilization before transfer, missing summaries, or contradictory handoff documentation can convert a clinical deterioration case into an institutional transfer-integrity case.

R9-10-212 — Patient Rights

Arizona’s patient-rights rule materially expands the scope of many cases. Serious hospital matters involving ignored patient or family concerns, inadequate notice, dignity violations, complaint-sensitive handling, refusal-of-treatment disputes, or coercive conduct can often be framed not only as negligence issues but as failures of patient-rights compliance. This is especially important where the hospital later claims that the patient or family was fully informed but the chart and conduct do not support that assertion.

R9-10-213 — Medical Records

Arizona’s medical-record rule gives documentation defects direct regulatory significance. In litigation, missing deterioration-window notes, inconsistent timestamps, fractured authorship, weak discharge documentation, absent handoff content, and narrative drift after the event do not merely create impeachment opportunities. They undermine the credibility of the hospital’s regulated record system itself. In high-value Arizona matters, documentation instability frequently becomes one of the most damaging institutional themes in the case.

R9-10-217 — Emergency Services

Emergency-response failures carry extra weight in Arizona because emergency services are specifically regulated. Delay in evaluation, poor triage, inadequate stabilization, weak cross-service communication, and thin emergency documentation can therefore be framed not just as individual care failures, but as breakdowns in a regulated hospital service line.

R9-10-230 — Infection Control

Arizona’s infection-control rule is one of the most important provisions for institutional-liability analysis. The hospital must establish an infection-control program designed to prevent development and transmission of infections and communicable diseases. The rule requires identification and documentation of infections, analysis of infections and communicable diseases, development of corrective measures, collection and analysis of infection-control data, actions taken related to infections and communicable diseases, and reports of communicable diseases to governing authority and state and county health departments. This gives infection and outbreak cases major systems-level depth.

Communicable Disease and Outbreak Reporting Under 9 A.A.C. 6

Arizona separately imposes public-health reporting obligations outside the hospital licensing article. Communicable disease reporting is mandated under R9-6-202, R9-6-203, and related provisions. ADHS outbreak-reporting materials direct administrators of health care institutions to report communicable disease outbreaks immediately to the local health agency. That means infection-sensitive Arizona cases may involve a second, faster, regulator-facing chronology distinct from the internal hospital record.

R9-10-232 — Disaster Management

Arizona’s disaster-management rule adds another important layer in service interruption, evacuation, environmental hazard, or infrastructure failure cases. These matters should not be treated as operational inconveniences. Where patient harm is connected to power loss, mass-casualty strain, failed emergency coordination, or hospital-wide disruption, Arizona’s disaster-management requirements allow counsel to frame the event as a systems-preparedness failure.

HAI Surveillance and Arizona’s Public Health Infrastructure

Arizona also operates within a broader healthcare-associated infection surveillance environment. CDC publishes Arizona-specific HAI progress data, and ADHS has maintained NHSN-related surveillance access and validation activity. In infection litigation, that means the case may extend beyond bedside causation into broader questions of surveillance quality, institutional trend recognition, and whether the hospital’s infection narrative fits the larger public-health and reporting environment.

Core legal reality: Arizona hospital liability often turns on whether the institution recognized the seriousness of the event, activated quality-management, discharge, transfer, emergency, and infection-control systems appropriately, preserved a stable chart, and kept its clinical and public-health narratives aligned.

High-Value Litigation Patterns in Arizona

Failure to Rescue / Delayed Recognition Cases

These are among the strongest Arizona hospital matters because they often expose both bedside negligence and institutional quality-management failure. Common patterns include delayed response to abnormal vital signs, missed sepsis progression, delayed physician notification, monitor failure, failure to act on critical laboratory values, and inadequate post-procedural observation. These cases become materially stronger when the chart suggests mounting danger but the hospital’s administrative and quality systems did not react with the urgency the situation required.

Discharge Failure and Premature Release Cases

Arizona is particularly important for discharge-sensitive litigation because discharge planning and discharge are expressly regulated. Premature discharge, poor follow-up arrangements, inadequate warning signs, weak caregiver instruction, unstable medication-transition planning, and discharge despite unresolved deterioration can become strong institutional cases rather than mere disagreements about physician judgment.

Transfer Breakdown Cases

Transfer-sensitive Arizona cases often gain value quickly because transfer is separately regulated. Delayed escalation to higher level of care, failure to stabilize before transfer, weak acceptance communication, incomplete transport documentation, or fragmented handoff can transform what appears to be a clinical case into a broader institutional continuity and transfer-integrity case.

Infection Control, Reportable Disease, and Outbreak Cases

Infection cases are especially strong in Arizona because they may implicate the hospital infection-control rule and the separate communicable-disease and outbreak reporting structure. Delayed isolation, weak infection documentation, failure to recognize a cluster, poor corrective action, contaminated equipment, resistant-organism drift, or weak reporting to state and county health authorities can broaden one infection case into a major institutional systems case.

Emergency Department and Stabilization Failures

Because Arizona expressly regulates emergency services, serious ED cases are often especially important. Delayed evaluation, weak triage, poor escalation from ED to inpatient services, inadequate stabilization, and thin emergency documentation can create both clinical and regulatory exposure. These matters are often strongest when the defense later characterizes the event as routine despite a record suggesting obvious instability.

Patient Rights, Complaint, and Communication-Sensitive Cases

Cases involving ignored patient or family warnings, inadequate explanation of condition, refusal-of-treatment conflict, dignity concerns, or complaint-sensitive administrative response can become particularly significant in Arizona because patient rights are formally regulated. These cases frequently strengthen where the hospital later asserts that communication was adequate but the chart and conduct do not support that position.

Disaster, Service Interruption, and Facility-System Cases

Arizona’s disaster-management obligations make system-interruption cases especially important. Events involving mass-casualty strain, service outage, environmental failure, or broader hospital disruption often become much stronger when patient harm can be tied to weak preparedness or poor institutional execution under emergency conditions.

Strategic lens: Arizona is not only a bad-outcome jurisdiction. It is a jurisdiction where discharge planning, transfer handling, infection-control activity, emergency response, patient-rights compliance, and record integrity often reveal whether the hospital truly recognized and managed danger as an institutional problem.

Timeline Forensics — Advanced Reconstruction of Arizona Institutional Response

Arizona cases should almost always be reconstructed through multiple interacting timelines: the clinical timeline, the administrative / quality-management timeline, the discharge or transfer timeline, the infection-control and public-health timeline, the emergency-services timeline, and the medical-record timeline. Where those timelines diverge, institutional credibility weakens quickly.

Phase 1 — Clinical Recognition

The first issue is when the hospital had enough information to know the matter had crossed out of routine clinical management and into serious-event territory. This may arise from rapid deterioration, severe infection, operative complication, failed rescue, major medication harm, transfer instability, ED decompensation, or a cluster of symptoms suggesting communicable disease. In Arizona, this recognition point matters because all later quality, discharge, infection, and public-health duties depend on whether the institution appreciated the seriousness of the event in real time.

Phase 2 — Internal Escalation

Next determine whether the event moved quickly enough from bedside staff to charge nursing, treating physicians, administration, quality personnel, infection prevention, emergency leadership, and other relevant departments. Strong Arizona cases often expose lag here. The chart reflects real danger, but the institution does not administratively behave as though it is facing a significant patient-safety event until much later.

Phase 3 — Classification Decision

This stage asks whether the hospital accurately understood what kind of event it was facing. Was it treated as routine progression when it was actually failed rescue, unstable discharge, unsafe transfer, ED stabilization failure, reportable infection, or outbreak-sensitive occurrence? In Arizona, misclassification is often where institutional weakness begins to compound because the wrong classification distorts quality review, infection response, and record development.

Phase 4 — External Reporting and Public-Health Exposure

Once the event is recognized properly, the next issue is whether the hospital activated the correct external-facing obligations. Was communicable disease reporting required under 9 A.A.C. 6? Was there a cluster or outbreak requiring immediate contact with the local health agency? Did infection-control documentation and health-department reporting align? A delayed or softened public-health chronology can become one of the strongest institutional-liability themes in the case.

Phase 5 — Operational and Corrective Response

The next stage asks what the hospital actually did. Was discharge reconsidered? Was transfer delayed until stabilization? Were infection-control corrective measures implemented? Were emergency-service resources escalated? Did quality personnel meaningfully engage? Was the chart kept current and internally consistent while the event unfolded? The strongest Arizona cases often show not only a bad event, but a weak or fragmented operational response after the hospital had enough information to act.

Phase 6 — Narrative Consistency

The final comparison is whether the chart, emergency documentation, discharge or transfer record, infection-control materials, any public-health reporting conduct, and later testimony all align. Arizona cases become especially dangerous when the medical record suggests a broader institutional problem, but the later defense narrative treats the matter as isolated and clinically unavoidable.

High-value timing question: When did the hospital have enough information to recognize the matter as a serious institutional event, and does every later step — escalation, classification, discharge or transfer handling, infection response, public-health reporting, and narrative explanation — move consistently from that point?

Federal Overlay — How CMS Standards Amplify Arizona Exposure

Arizona’s state structure is already substantial, but the strongest hospital cases often become materially more dangerous when the same facts also implicate federal Conditions of Participation. The best Arizona cases are usually those in which the same occurrence appears deficient clinically, deficient under Arizona hospital rules, and deficient under federal participation standards.

Quality Management and Governing Oversight Convergence

Arizona’s quality-management requirements align naturally with federal quality assessment and performance improvement expectations. When a serious event reveals weak institutional monitoring, poor escalation pathways, or fragmented administrative follow-through, the same facts may support both state and federal institutional-failure theories.

Discharge Planning and Continuity Convergence

Arizona’s explicit regulation of discharge planning and discharge overlaps with federal discharge-planning expectations. Inadequate follow-up, poor caregiver instruction, incomplete planning, and unstable discharge timing can therefore become objective institutional evidence rather than merely sympathetic facts.

Patient Rights and Documentation Convergence

Arizona’s patient-rights and medical-record rules also align naturally with federal patient-rights and documentation expectations. Ignored family concerns, poor notice, incomplete records, unstable chronology, and missing handoff material can therefore become objective institutional evidence rather than mere impeachment points.

Emergency Services and Stabilization Convergence

Because Arizona expressly regulates emergency services, ED-sensitive cases often overlap with federal expectations around hospital emergency capability, screening, stabilization, and coordinated response. Weak triage or poor stabilization can therefore carry dual significance.

Infection Prevention Convergence

Arizona’s infection-control requirements, communicable-disease reporting duties, outbreak-reporting tools, and HAI surveillance environment align naturally with federal infection-prevention expectations. When a hospital misses a cluster, delays isolation, or fails to respond coherently to a communicable-disease problem, exposure compounds quickly.

Federal leverage point: In Arizona, the strongest hospital cases are often those where quality-management failure, unstable discharge or transfer handling, infection-control weakness, emergency-service breakdown, and record instability all converge with federal participation standards to show that the institution’s systems were not functioning safely.

Litigation Implications — Advanced Institutional Liability Analysis

Arizona hospital litigation should not be approached as a simple negligence problem. It should be approached as a multi-document, multi-timeline, institution-level credibility problem. The strongest theories usually show that the outcome was not merely unfortunate, but that the hospital’s own operational and reporting structure exposed deeper institutional weakness.

Failure of Institutional Recognition and Escalation

One of the strongest Arizona liability themes is that the hospital did not recognize or escalate the event with the seriousness its own systems required. This may appear as delayed physician escalation, passive quality response, failure to reconsider discharge, weak infection-prevention involvement, or poor emergency-service coordination. These failures are stronger than ordinary hindsight allegations because Arizona expects organized hospital systems, not ad hoc reactions.

Discharge or Transfer Failure as a Liability Multiplier

Arizona cases often become materially more dangerous when the continuity process does not fit the clinical reality. If discharge planning was weak, if the patient was transferred without adequate stabilization or communication, or if the discharge or transfer narrative later changes, the case quickly evolves from a bedside dispute into an institutional continuity and systems-integrity failure.

Infection Surveillance and Reporting Failure

In Arizona, infection cases gain value sharply when the hospital had enough information to suspect communicable disease, cluster conditions, or outbreak-sensitive events but did not respond through infection-control documentation, corrective measures, or health-department reporting in a timely and coherent manner. These cases are often stronger than routine infection-negligence disputes because the state expects structured institutional action.

Documentation Integrity as Institutional Evidence

Arizona cases often become more dangerous when charting is unstable. When bedside notes, emergency records, transfer materials, discharge documentation, infection-control chronology, and later institutional explanations do not align, the case quickly stops being about whose expert sounds more persuasive and becomes a question of why the hospital generated different versions of the same event.

Expansion from Provider Fault to Institutional Fault

A provider-centered case can evolve into an institutional case very quickly in Arizona. The reasons are predictable: hospital rules require organized administration, quality management, discharge planning, transfer handling, patient-rights compliance, medical records, emergency services, infection control, and disaster management; public-health rules create a second reporting track in outbreak-sensitive cases; and the broader HAI surveillance environment adds institutional trend-recognition expectations. This shift often changes valuation materially because institutional-failure theories are more durable than provider-only negligence theories.

Settlement and Trial Impact

An Arizona case with weak discharge or transfer chronology, unstable records, poor infection-control response, delayed public-health contact, and a drifting institutional narrative will usually carry greater settlement pressure than a similar bedside-only negligence case. At trial, the narrative is stronger: the hospital did not merely make an error; it failed to recognize, organize, document, and respond to the event in the way Arizona’s own structure expects.

Closing litigation insight: The strongest Arizona cases show not only that the patient was harmed, but that the hospital’s own quality, discharge, transfer, infection-control, emergency, and recordkeeping framework revealed a deeper institutional failure it could not credibly explain away.

Attorney Application

For Plaintiff Counsel

  • Determine whether the event exposed a breakdown in Arizona-required hospital systems such as quality management, discharge planning, transfer handling, patient rights, infection control, emergency services, or medical records.
  • Map the bedside chronology against administrative escalation, discharge or transfer decisions, infection-control activation, and any communicable-disease or outbreak-reporting obligations.
  • Use Arizona’s discharge and transfer rules to frame continuity failures as institutional breakdowns rather than only physician judgment calls.
  • Use the infection-control rule and outbreak-reporting framework to strengthen infection and communicable-disease cases.
  • Use patient-rights rules where patients or families raised concerns that were ignored, minimized, or poorly documented.
  • Use medical-record requirements to widen charting defects into institutional credibility and compliance problems.

For Defense Counsel

  • Build a disciplined chronology showing when the hospital recognized the event and how it moved through quality, discharge, transfer, infection-control, and emergency pathways.
  • Demonstrate coherent coordination between bedside staff, administration, infection prevention, emergency leadership, and any public-health reporting obligations.
  • Address communicable-disease, cluster, outbreak, and HAI-sensitive dimensions directly where they exist rather than leaving them implicit.
  • Show that discharge and transfer decisions were real, timely, individualized, and supported by documented clinical reassessment.
  • Stabilize the institutional narrative before discovery fractures credibility across charting, emergency documentation, discharge materials, and regulator-sensitive conduct.
Best use of this guide: Arizona hospital chronology reconstruction, ADHS-sensitive discovery planning, discharge and transfer analysis, infection-control and outbreak review, institutional liability modeling, and expert packet development.

When to Engage Lexcura Summit

Arizona hospital matters often justify early clinical-regulatory review because the strongest liability themes usually emerge from the interaction between the chart, quality management, discharge planning, transfer handling, infection-control systems, communicable-disease duties, emergency response, and medical-record integrity. Lexcura Summit is typically engaged when counsel needs more than a chronology and requires disciplined analysis of causation, escalation failure, systems exposure, and reporting integrity.

Engage Early When the Case Involves:

  • Unexpected death, catastrophic injury, or major deterioration with unclear institutional escalation history
  • Failure to rescue, sepsis, delayed physician notification, or monitor failure
  • Possible hospital-acquired infection, delayed isolation, communicable-disease exposure, or weak infection surveillance
  • Outbreak-sensitive conditions or unclear Arizona public-health reporting history
  • Premature discharge, poor follow-up planning, failed transfer, or continuity breakdown
  • Emergency department delay, poor stabilization, or weak ED documentation
  • Ignored complaints, unaddressed family warnings, or patient-rights-sensitive failures
  • Documentation inconsistency suggesting institutional narrative drift
  • Potential institutional liability extending beyond one provider

What Lexcura Summit Delivers

  • Litigation-ready medical chronologies with event-sequence precision
  • Standards-of-care and escalation analysis tied to Arizona hospital rules and institutional operations
  • Institutional exposure mapping across quality management, discharge planning, transfer systems, infection control, emergency response, patient rights, and record integrity
  • Physiological causation analysis in deterioration and rescue-failure cases
  • Strategic support for deposition, mediation, discovery planning, and expert preparation
Strategic advantage: Early review helps counsel identify whether the case is fundamentally a bedside-negligence matter or a broader Arizona systems-and-reporting case with materially higher institutional value.

Closing Authority Statement

Arizona hospital liability is defined not solely by the clinical outcome, but by the institution’s ability to recognize, organize, document, and respond to serious events within a layered licensure and public-health framework. Through 9 A.A.C. 10, Article 2, Arizona imposes formal requirements governing hospital administration, quality management, discharge planning, transfer, patient rights, medical records, emergency services, infection control, and disaster management. Through 9 A.A.C. 6 and related ADHS outbreak-reporting mechanisms, Arizona separately imposes communicable-disease and outbreak-reporting duties. Through the state’s HAI surveillance environment, Arizona also places hospital infection performance within a broader public-health and benchmarking framework.

The analysis therefore begins with clinical reality. Where the medical record reflects major deterioration, severe infection, unsafe discharge, failed transfer, emergency-service breakdown, operative harm, cluster conditions, or another serious patient-safety occurrence, the hospital is expected to recognize that the event has moved beyond ordinary care variation and into institutionally significant territory. When recognition is delayed, incomplete, or internally fragmented, institutional accountability begins from a weakened position.

From that point, the inquiry advances to escalation and classification. Arizona’s structure requires hospitals to act through organized systems: administration, quality management, discharge planning, transfer handling, patient-rights protections, medical records, emergency services, infection control, and disaster management. Where the institution delays escalation, minimizes the significance of infection or outbreak signals, fails to recognize discharge or transfer risk, or allows records to become unstable, the issue is no longer limited to clinical care. It becomes a question of whether the hospital accurately understood and managed the event at all.

The next layer examines operational response. Arizona requires real quality oversight, real discharge and transfer processes, real infection-control systems, real emergency-service capability, and real record integrity. A serious case therefore does not end with whether a provider made a mistake. It extends to whether the hospital’s licensed operational systems were current, coordinated, and actually functioning when the patient needed them most.

The analysis then converges on documentation and narrative consistency. The most consequential Arizona cases are those in which the bedside chart, emergency documentation, discharge or transfer record, infection-control chronology, any communicable-disease or outbreak-reporting conduct, and the institution’s later testimony do not align. When the hospital tells one story in contemporaneous records and another through later explanation, that discrepancy becomes more than impeachment material. It becomes evidence that the institution cannot present a coherent and reliable account of what occurred.

This progression — recognition, escalation, discharge or transfer response, infection and public-health response, documentation, and narrative integrity — creates a compounding liability framework. Delayed recognition weakens escalation. Weak escalation distorts operational response. Deficient operational response destabilizes records and continuity. And unstable records and inconsistent explanations amplify exposure at every later phase of litigation.

Arizona’s structure is designed to expose precisely this kind of compounding institutional failure. It does not ask only whether harm occurred. It asks whether the hospital responded to harm in a manner consistent with its obligations to patients, regulators, public-health authorities, and its own licensed systems.

Judicial Framing:
Where a hospital fails to timely recognize a serious event, does not escalate it through quality, discharge, transfer, infection-control, emergency, recordkeeping, and reporting systems, neglects communicable-disease obligations where applicable, and advances a narrative inconsistent with the clinical record, the resulting harm is not attributable to isolated clinical judgment alone — it is attributable to institutional failure across multiple operational and regulatory layers.

Definitive Conclusion:
The most compelling Arizona hospital cases establish that liability is not created by a single adverse event, but by the institution’s cumulative failure to recognize, classify, escalate, document, discharge, transfer, report, and accurately account for that event. In these cases, the central issue is not whether an error occurred, but whether the hospital’s systems functioned with sufficient integrity to respond when it did. Where they did not, liability becomes both foreseeable and difficult to defend.
