All cases are constructed composites set on a fictional surgical unit. No real patient or clinician is described.
Introduction and Method
Surveillance is a word nurses use daily and rarely define. This paper analyzes it using the eight-step method of Walker and Avant (2019), which adapts the approach to concept analysis first set out by Wilson (1963). The steps are to select a concept, determine the aims of the analysis, identify its uses, determine defining attributes, construct a model case, construct additional cases, identify antecedents and consequences, and define empirical referents.
Aims of the Analysis
The aim is practical. Failure to rescue, death after a complication that could have been recognized and treated, is often traced to deterioration that was measured but not acted on. Vital signs were charted, but no one interpreted the trend. If surveillance means something more than taking measurements, its attributes should be stated precisely enough to distinguish it from routine monitoring and to be measured in studies of patient safety.
Uses of the Concept
In public health, surveillance refers to the ongoing, systematic collection, analysis and interpretation of data about disease in a population, used to plan and evaluate action. In security and ordinary speech, it means close watching of a person or place, often with the implication of suspicion. Both uses share sustained attention and the purpose of acting on what is observed.
In nursing literature, surveillance is described as the purposeful and ongoing acquisition, interpretation and synthesis of patient data for clinical decision-making. Dresser (2012) describes nursing surveillance as a process that links assessment to action and identifies it as central to preventing adverse events. Kutney-Lee et al. (2009) developed a measure of a hospital's capacity for surveillance, treating it as a property of nurses' practice environment as well as of individual nurses. The nursing use keeps the public health emphasis on interpretation and action and drops the security sense of suspicion.
Defining Attributes
Three attributes define nursing surveillance.
1. Sustained attention to one patient over time. Surveillance is not a single observation but a continuous process of attending to the same patient across hours.
2. Interpretation of cues against an expected course. The nurse compares what she observes with what should be happening for this patient at this point, and recognizes when the two diverge.
3. Readiness to act on the interpretation. Surveillance includes the intention and the means to respond, whether by intervening or by escalating to another clinician.
Model Case
A composite 64-year-old man is on a surgical unit after an open colectomy, receiving hydromorphone by patient-controlled analgesia. His nurse checks him every hour overnight. At 2 a.m. his respiratory rate is 12 and his oxygen saturation 95 percent; at 3 a.m. the rate is 10 and he is harder to rouse. She compares this with his expected course, recognizes a downward trend in rate and level of consciousness consistent with opioid effect, stops the analgesia pump per protocol, applies oxygen and calls the rapid response nurse. All three attributes are present: sustained attention across hours, interpretation against an expected course and action on that interpretation.
Borderline Case
On another night, the same patient's oxygen saturation is watched through a remote pulse oximetry system by a technician in a central station. The technician attends continuously and alerts the nurse when saturation falls below 90 percent, but cannot interpret his respiratory rate, sedation level or opioid dose. Sustained attention and readiness to act are present; interpretation against an expected course is not. This is close to surveillance but is not the whole concept.
Related Case
A nurse records the patient's vital signs every four hours as ordered. Each value is within its individual normal range, and she enters them in the chart without comparing them with earlier readings. This is monitoring: data are collected accurately, but there is no interpretation against a trend and no readiness to act. Monitoring is related to surveillance and is often mistaken for it.
Contrary Case
A nurse caring for six patients charts the man's vital signs on schedule, but the values are copied forward from the previous entry because she did not reach his room. Nothing was observed, interpreted or acted on. This case shows clearly what surveillance is not.
Why the Distinction Matters
The cases show that surveillance and monitoring differ in kind, not only in degree. Monitoring produces data; surveillance produces judgments. A unit can increase monitoring, by adding continuous pulse oximetry or more frequent vital signs, without increasing surveillance at all, if no one is positioned to interpret what the devices record. The borderline case illustrates the risk: a technician watching a screen is attentive and ready to call, but the call comes only when a single number crosses a threshold. The nurse in the model case recognized a trend in two measures, respiratory rate and level of consciousness, before either crossed a threshold. That difference, interpretation of a pattern against an expected course, is the attribute most often missing when failure to rescue is investigated, and it is the attribute technology is least able to supply.
Antecedents and Consequences
Antecedents are conditions that must exist before surveillance can occur: nursing knowledge of the expected postoperative course and of opioid effects, a workload that allows repeated contact with the patient, access to trend data and an escalation system that responds when called (Kutney-Lee et al., 2009). Consequences are the results of surveillance: earlier recognition of deterioration, timely intervention or escalation, and, at the level of the unit, lower rates of failure to rescue (Dresser, 2012).
Empirical Referents
Surveillance can be measured through indicators such as the time from the first abnormal cue documented in the record to escalation or intervention, the proportion of documented vital sign entries that include a comparison with the previous value, and the frequency of documented reassessment after an opioid dose. A study of surveillance on surgical units could adopt these indicators, which are distinct from the defining attributes because each can be counted.
This analysis has limits. It draws on a small number of nursing sources and constructs its cases in a single setting, the postoperative surgical unit, so its attributes may need adjustment in settings such as home health or critical care, where the expected course and the means of action differ. It also treats surveillance as an activity of individual nurses, while some authors describe it as a capacity of the unit or hospital. A further analysis could test whether the three attributes hold when surveillance is shared across a team. That question matters for staffing decisions, since a unit can only rely on shared surveillance if someone is clearly responsible for interpreting each patient's trend.

How this MN502 Unit 6 example is structured
An introduction states the concept and the method, citing Walker and Avant directly and noting that their approach descends from Wilson's earlier work. Aims come next, framed as a practice problem rather than an academic curiosity. The uses section is kept short on purpose, a paragraph on each non-nursing sense and then the nursing literature, so the analysis does not stall in definitions. Defining attributes follow, each argued from the literature rather than asserted. The model case contains all three attributes; a borderline case contains two, remote pulse oximetry watched by a technician who cannot interpret it; a related case examines monitoring; the contrary case shows vital signs charted on schedule with no attention to trend. Antecedents and consequences are then set in two lists, and empirical referents close the analysis with measurable indicators a later study could adopt.

MN502 Unit 6 questions, answered
How do I choose a concept for Unit 6?
Pick one that matters in your practice and has enough literature to analyze, but not so much that it has been settled many times over. Concepts such as surveillance or vigilance work because nurses use them often and define them loosely. Very broad terms like health or caring tend to overwhelm a single paper and leave the attributes vague.
Do I have to use Walker and Avant's method?
Only if your section specifies it. Rodgers's evolutionary method and other approaches are accepted in many courses, and each has different steps. Whichever you use, name it early, cite its originator directly, and follow its steps in order. Mixing methods without saying so is a common reason concept analyses lose marks.
What makes a good borderline case?
A borderline case contains most but not all of the defining attributes, so it sits just outside the concept. Its value lies in showing which attribute is essential. In the strongest samples it is the model case with one attribute removed, and the paper explains why that single loss disqualifies it from counting.
