Overview
What is mobile in mobile health: the clinician, the nurse, or the information? Why should information move? What role does mobile health play in hospital information management? This article addresses those questions. Clinical incidents in hospitals can have high safety significance. As a practicing physician, I see that many staff participate in care delivery; when many people are involved, the risk of safety or quality incidents increases. Compared with other industries, healthcare risk levels are very high, so improving medical safety and quality is a major IT challenge.
IT should help hospitals improve patient safety and quality of care. Key goals include continuous improvement of clinical quality, better patient experience, and refined modern hospital operations across staff, finance, and supplies. Information systems play an essential role in achieving these goals.
Closed-Loop Management Ensures the "Five Rights"
Is IT the solution to these challenges? Beyond narrow electronic medical records, EMR maturity is often graded on a 0–7 scale. Level 6 focuses on safety and quality: all information is recorded and structured, clinical decision support systems (CDSS) are in place, and closed-loop management exists. When a physician issues an order and the patient receives therapy, the entire process becomes a closed loop that enables verification of the five rights: correct patient, correct time, correct medication, correct route, and correct dose. Achieving this largely eliminates medication errors. HMISS established the EMR grading standard years ago and level 6 emphasizes safety and quality. Ensuring safety and quality should be the ultimate goal of digitization; beyond that is standardization, which I view as the highest development direction for health information systems.
1. What Is Closed-Loop Management?
Closed-loop management means the entire clinical process is electronically recorded: from outpatient physician orders to pharmacy dispensing or automated dispensing, to confirmation of patient identity and final administration. Each step is logged so any problem can be traced to a specific link in the chain. In HMISS evaluation, level 6 indicates such closed-loop capabilities. Even in advanced healthcare systems internationally, not all hospitals have reached this level.
2. Mobile Health Focused on Safety and Quality
IT is only one part of improving hospital quality. Historically hospitals required physicians and nurses to guarantee quality and safety, but they only control specific points in a broader system. A hospital comprises three levels: the hospital management systems (supply chain, consumables, equipment), the clinical process (team workflows and institutional rules), and measurable quality improvement. IT is as fundamental as utilities like water and electricity at the hospital level.
Peking University People's Hospital (People's Hospital) implemented mobile health primarily to improve safety and quality, addressing three levels: 1) enabling end-to-end traceability to close the loop so the last step of medication administration is captured in the information system; 2) enabling point-of-care verification of patient identity and treatment to prevent errors; and 3) enabling statistical analysis and root-cause evaluation of adverse events to improve clinical quality. These are the main relationships between mobile health and clinical care.
Previously, hospital IT was office-centric and desktop-based. Information systems stopped at the office; there was no digitization at the bedside. To complete the last 20 meters of clinical informatics, systems must reach the bedside. Without that, many medication errors persist. U.S. data on medication incidents without IT support show that 39% result from physician ordering errors (wrong drug, wrong dose, missed allergies), 12% arise from transcription or nurse execution errors, 11% from pharmacy dispensing errors, and 38% from bedside administration. A mobile system should aim to eliminate these errors rather than using tablets as a showpiece.
3. Mobile Nursing Has Higher Priority Than General Mobile Health
I have not seen a company in China that provides complete medication lifecycle records: every tablet prescribed, when the pharmacist picked it from the shelf, which nurse received it, which patient was given the medication, and confirmation of ingestion. Where such records exist, they are often incomplete. Many hospitals use unit-dose packaging machines with barcode labels, but bedside verification is frequently omitted. The clinical protocol known as the "three checks and seven rights" is thus undermined in practice. Some hospitals do not even retain clear packaging labels, which can result in medication mix-ups. In 2009 People’s Hospital experienced a fatal medication error. Preventing such errors justifies the investment. Therefore, I consider mobile nursing a higher priority than other mobile health initiatives.
Measures to Ensure Effective Mobile Nursing
In July 2010 we began implementing mobile nursing, covering operating room handovers, blood product transfers, and ward medication administration. The primary devices were PDAs; we selected industrial-grade mobile devices from Motorola for durability and reliability. The hospital has roughly 53,000 annual discharges, so industrial-grade hardware was a priority.
Operationally, medication dispensing and preparation must be performed with two nurses, each using a PDA to verify medications. Previously the "three checks and seven rights" protocol was often poorly implemented due to staffing and workflow pressures. With PDA-assisted barcode scanning of patient wristbands, the system alerts automatically for mismatches. If a medication does not match the order, if the order does not exist, or if the administration is outside the correct timing window, the system blocks or flags the action.
For specimen collection and laboratory compliance with ISO 15189 standards, PDAs record whether a test is indicated, confirm the patient identity, and timestamp the draw without adding nurse workload. For nursing rounds, nurses scan patient wristbands and use infrared scanning of bedside cards to verify they reached the bedside, ensuring rounds are performed. Admission time is recorded when the nurse scans the wristband at the bedside, providing a more accurate timestamp than administrative admission time.
Sterile supply management is included in the closed loop: from cleaning and packaging to sterilization and issue, each package is traceable. We can identify which washer or sterilizer processed an item, who packaged it, who sterilized it, and who issued it. During dressing changes staff scan patient wristbands so that any cross-contamination or sterilization failure can be traced.
Nursing documentation was reorganized to reduce workload: many records were structured as selectable items rather than free text. Nurses can scan a patient wristband and document education items from preset lists; each item is checked off and timestamped. This captures individual actions and allows supervision of completed tasks.
When an order is executed successfully, it is visible to the physician in real time. Vital signs capture, temperature charting, high-risk patient alerts, and analytics are all integrated. To ensure system use, we defined monitoring indicators. For example, with about 1,700 inpatients at a given time, we monitor whether admission scans were completed for each patient. From April onward, we required monitoring of all nurses and tracked completion rates. Missing scans are investigated individually. Noncompliance reasons fall into three categories: medication prepared outside the ward, emergency resuscitation, and crisis situations where verification may be bypassed. Identifying these categories provides reasonable assurance that missing actions are justified.
Health education and some nursing records revealed gaps. For example, patient education was often performed only at initial admission and not repeated, so completion rates were inaccurate. Routine nursing documentation schedules (level 1: daily; level 2: twice weekly) must be enforced and audited.
