The hospital and all figures are composite and bracketed where they are the student's own; the evaluation framework and research cited are published.
Why This Framework
The framework was chosen before any data were gathered, so that the evaluation could not select only flattering measures. DeLone and McLean's updated model of information systems success asks six separate questions, each taken in turn below: how well the system itself performs, how good its information is, how good the support around it is, whether nurses actually rely on it, whether they are content with it, and what it achieves for patients and staff (DeLone & McLean, 2003). It fits this system because it separates three questions that can come apart: whether a system runs well, whether it is used, and whether its use produces benefit. A pump integration can be widely used and still fail patients if the data it sends are wrong, or run flawlessly and be bypassed by nurses who do not trust it. Each dimension below is measured with the best available source, and weaker sources are labeled as such.
System Quality
Measure: share of auto-programming attempts that fail for technical reasons. Result: [9.8] percent of attempts in month six failed, most because the pump lost its wireless connection. Failures clustered in [three] rooms at the ends of two halls and in the hour after shift change, when many pumps reconnect at once. Reading: the system works most of the time, but its failures are predictable in place and time, which means they can be fixed.
Information Quality
Measure: point prevalence audits, in which every running infusion on the audit day is checked against its active order for drug, concentration, dose, rate and patient. Result: before integration, [89] discrepancies among [612] running infusions, 14.5 percent. At six months, [36] among [588], 6.1 percent. Reading: the largest safety gain. Most of the remaining discrepancies involved infusions programmed manually after a fallback, or titrations entered by hand.
Service Quality
Measure: time to resolve help desk tickets about the integration, and nurses' ratings of support. Result: median resolution of [26] hours; [41] percent of tickets reopened. Night shift reports went unanswered until morning in most cases. Reading: support is the weakest dimension, and night support in particular, because the informatics team works days and the vendor line is not staffed by clinicians.
Use
Measure: share of eligible infusion starts that are auto-programmed. Result: 14,368 of 18,420 eligible starts in month six, 78.0 percent. Use varied by unit from [64] to [89] percent. Reading: high but uneven use, and use alone says nothing about whether the auto-programmed values were correct.
User Satisfaction
Measure: a short survey of nurses on the six integrated units, [212] of [340] responding. Result: [72] percent agreed the integration made infusion programming safer; [58] percent agreed it saved time; [44] percent agreed that it added steps they did not have before, most often the channel scan and the flowsheet validation. Reading: perception, not measurement. It is useful for knowing where nurses feel friction, and it points to the added steps as the main complaint.
Net Benefits
Measure: changes in patient safety and work, drawing on the other dimensions. Result: fewer infusion discrepancies; documentation of running rates available immediately rather than when a nurse returned to the workstation; and, a finding the old process could not produce, [four] events in six months in which pump data posted to the wrong patient's chart.
The New Risk: Wrong-Chart Association
The wrong-chart events deserve their own section because they are a new kind of error created by the system. In each case, a pump channel had been associated with one patient and not released when the pump moved to another bed. The running rate from the second patient's infusion then posted to the first patient's flowsheet. In two cases, a nurse noticed a rate on a patient who had no active infusion; in the other two, the discrepancy was found in retrospective review. No patient was harmed, but the error is invisible to the nurse at the bedside, because the pump itself shows the correct rate; only the record is wrong.
A sociotechnical view expects this. Health information technology changes work in complex ways, and a new system brings failure modes of its own, born where devices, software, clinicians, routines and the institution meet (Sittig & Singh, 2010). National guidance on smart pumps also calls for processes to confirm pump and patient association and to monitor interoperability data for errors (Institute for Safe Medication Practices, 2020).
How the Dimensions Relate
The model's value lies in how its dimensions connect, and the figures show those connections here. System quality limits use: on the units with the worst wireless coverage, auto-programming ran on as few as [64] percent of starts. Use drives information quality: most remaining discrepancies occurred on infusions programmed by hand, so every point of use gained is likely to remove discrepancies. Service quality shapes satisfaction: nurses on nights, who waited longest for help, reported the lowest agreement that the system saved time. And net benefit depends on all of them at once, including a failure, wrong-chart posting, that none of the other dimensions would reveal on its own. An evaluation that reported only the 78 percent use figure, which is the number leadership most often cites, would have missed every one of these links.
Overall Judgment
The integration is succeeding on its central purpose. Information quality improved substantially, consistent with reports from other hospitals that implemented interoperability (Biltoft & Finneman, 2018). Use is high. But the evaluation finds three weaknesses that a use-only report would hide: predictable wireless failures, weak support at night, and a new wrong-chart error that the bedside view cannot detect.
Recommendations
1. Fix the connection dead zones and stagger pump reconnection after shift change.
2. Provide night-shift support through an on-call informatics nurse for the next three months.
3. Require release of pump associations at every transfer, and add an automated alert when a pump channel remains associated with a patient who has left the unit.
4. Repeat the point prevalence audit quarterly, and add an audit of flowsheet infusion data against pump logs to catch wrong-chart postings.
5. Report all six dimensions to the steering committee each quarter, so that a rise in use is never read on its own as a rise in safety.

How this NU515 Unit 3 example is structured
An evaluation framework is chosen before any data, so the paper cannot select only flattering measures. DeLone and McLean's model fits because it separates whether a system runs well from whether it is used and whether use produces benefit; the three can diverge. Each dimension is measured with the best available source, and weaker sources, such as a satisfaction survey, are labeled as perception. Safety evidence carries the most weight, and the audit is described with its method: every running infusion on audit days checked against its order. The new-risk section receives the same care as the benefits, since stale associations are a hazard the old manual workflow could not produce. Burden is reported by unit type rather than averaged, because intensive care nurses titrate often and gained least. A balanced verdict follows: keep the integration and fix it.

NU515 Unit 3 questions, answered
What is the DeLone and McLean model?
An information systems success model first published in 1992 and updated by DeLone and McLean in 2003. The updated version links system quality, information quality and service quality to use and user satisfaction, which together produce net benefits. The sample uses it because it keeps usage from standing in for success, a distinction that matters when a system is used widely but misfiles data.
What is a point prevalence audit of infusions?
A snapshot check in which every running infusion on selected units is compared with its active order at one moment: drug, concentration, rate, dose and patient. It measures discrepancies directly rather than relying on error reports, which undercount. The sample runs audits before and after integration so the two rates can be compared, and it reports the count behind each percentage.
Should an evaluation recommend removing a system?
Only if the evidence supports it. The sample finds a clear safety gain alongside real problems and recommends keeping the integration while fixing wireless coverage, disassociation workflow and library mismatches. An evaluation ending in removal needs evidence that harm outweighs benefit. Most evaluations end, like this one, with targeted improvements tied to measured weaknesses.
