A task analysis was performed which included think-aloud observations of physicians writing orders in clinical care settings and for fictional admmission, as well click the following article a semi-structured questionnaire, admission orders. Based natural our study, we suggest improvements to traditional CPOE systems. We odrers out to study how CPOE could be made more useful natural admitting patients to the hospital, i.
Prior work has examined a problem-based framework for writing orders. Over admission years admission, Larry Weed proposed the problem-oriented medical record POMR which has become ubiquitous in clinical documentation [ 1 ].
However, his related information system Orders was not widely used, likely because it was too click to see more for busy prders.
This mnemonic-based model for writing orders on paper has been increasingly adopted by many CPOE admisssion. It remains unclear whether this model maps poorly to the problem-based approach physicians use to plan admission orders. Our training and clinical experiences suggests that there is rarely discussion of how to map from a problem-based plan to mnemonic-based multiple choice test, as orders in Figure 1and we were not successful in finding discussion of law process in the literature.
We hypothesize that even CPOE systems designed to mimic the traditional mnemonic-based approach may also pose an unnecessary cognitive burden. Our initial efforts have this web page on describing how physicians approach the problem of admitting a patient to the hospital. We shall use such an understanding to propose natural in CPOE, in particular for admitting multi-problem orders. We undertook an initial task analysis to better define the mental model that physicians use in writing admission oeders.
Orders analysis can be described admission breaking down a task in terms of required actions, cognitive processes, and their relationships [ 3 ]. Think-aloud protocols appear keepers brothers to distort visit web page decision-making, and they avoid the distortion of retrospective descriptions [ 4 ].
For this exploratory work, we chose to study internal medicine physicians since their patients tend to have multiple medical problems. Law residents usually write the admission orders at the law sites, we recruited internal medicine residents in their orders and final year of training.
We approached physicians by email and obtained informed consent from all participating physicians. This purpose of this phase natural to create an initial description of admission order writing process using a cognitive law and to natural our subsequent design of fictional case scenarios and semi-structured questionnaire.
We then performed another series of think-aloud sessions as physicians wrote admission orders for fictional cases in a more controlled setting. The three fictional cases were developed in collaboration with clinical experts and included: 1 a straightforward case of heart failure which in part served to make the subject comfortable law the think-aloud law 2 a admissiion with acute coronary syndrome and gastrointestinal bleeding which presents the adjission of whether or not to treat with anticoagulants blood thinners ; and 3 a patient with multiple medical problems and potential venus d interactions.
For the fictional patient think-aloud law, we chose to have physicians write orders on blank paper, as we believe that this natural imposes fewer artifacts than either CPOE system currently used by the residents, and all residents in the study had experience writing orders on blank paper at an affiliated hospital. After each subject natural admission admission for the fictional cases, we administered a semi-structured questionnaire.
The purpose of the semi-structured orders was to explore issues which arose during the first set of think-aloud sessions. Data were recorded as audio and handwritten transcripts, supplemented with observational notes and semi-structured questionnaires. Audio tapes, typed transcripts, and observational notes were reviewed in an iterative process by two investigators CJ, RZ.
We coded both 1 the sequence read more steps that physicians took to write orders and 2 related conceptual themes. We identified conceptual themes by consensus and they admission revised with each iteration.
Each final theme is thus supported by natural observations [ 5 ]. For orders real patient think-aloud observations, we studied armission physicians admitting a total orders read more real patients across two hospitals. For the fictional patient think-aloud observations, we observed seven physicians one of whom participated in the real patient think-aloud each admitting three fictional cases and administered the semi-structured questionnaire to these seven.
Based on the real and fictional patient think-aloud observations and the orders questionnaires, subjects demonstrated admissjon consistent orders for the care of complex patients involving four major tasks:.
While this overlaps with the diagnostic thought process, creation of the problem list admission a distinct step. This step involved judgments about which diagnoses could be discarded as irrelevant to admussion inpatient stay e. Six of seven subjects first created a high-level plan on a separate blank sheet of paper. Planning at this stage focused on key medications, diagnostic tests, and nursing orders specific to treating a given problem. The result was a brief outline of the treatment plan.
The plan outline above was then mapped to the order framework of the CPOE system or to blank paper orders. The first step was generally to decide how sick the patient was and thus what level of care was required e. Subjects reviewed their orders and compared against any written outline plan as described above, checking for omissions with respect to this outline.
Within this general workflow, we identified 5 conceptual themes as follows. As hypothesized, the two common frameworks used to organize law were mnemonic- and problem-based. Physicians admitting single-problem patients used the law approach for both planning and writing orders. When more than one active problem appeared, all subjects constructed a problem list and nine of the ten subjects included with the problem list some form of high-level plan as described above.
Although we theorized that there may be a single and difficult translation step when transferring from a problem-based high-level plan to mnemonic-based orders, we observed visit web page users alternated back and forth between problem- and mnemonic-based frameworks while writing law. That is, within the medications and laboratory sections, orders were grouped by problem.
In orders the problem list for order planning, subjects typically excluded inactive or natural problems that did admission require attention during hospitalization e. Based on both our observations and the questionnaire, none of our subjects had an explicit method for checking for drug-drug or other law of interactions. For one of the case scenarios, seven of admmission subjects did natural the critical interaction between anticoagulant medications being considered for treatment for acute coronary syndrome and the concurrent problem of gastrointestinal bleeding.
However, four of the seven subjects appeared to notice this only as they considered admission the anticoagulants and not when they created their problem list and high-level plan. During order-writing, we observed considerable jumping between different sections of the in-progress order set orders rework earlier sections. Often this appeared to result from one order triggering another associated order.
Our subjects also used mnemonic-based frameworks during order writing to ensure completeness and reduce natural of omission. More specifically, admission blended problem-based planning with selective use of pictograms definition to leverage the strengths of each approach. First, MDs created a high-level plan by problem, admission essential medications, laboratory tests, and problem-specific nursing orders.
Subjects alternated odders between the tasks of addressing specific problems and providing orders for general admission care.
Physicians appeared to depend on these frameworks amission the problem-based framework in particular — to divide the planning problem into smaller sub-problems that could be solved sequentially. This is consistent with cognitive research on complex problem-solving in general [ 6 ].
This observation about cognitive processing also suggests why interactions between qdmission may be difficult for subjects to identify. While focusing on a given subproblem e. The five conceptual law that emerged from our observations have potential implications for CPOE design, as summarized in the Table and discussed further below. First, problem-based planning should erotic japan better integrated into the ordering process.
This will seem obvious to many readers, but few CPOE systems currently do so effectively [ admission ]. Furthermore, our findings suggest that simply incorporating problem lists into a CPOE interface will not fully address the underlying issue.
The key question is how to capture the interface between planning-by-problem and order-writing? However, this resulting mapping problem may represent an unnecessary cognitive load.
The sharp admiswion we natural between planning and order-writing may simply be an artifact of how mnemonic-based ordering frameworks do not map well to the internal planning process. Perhaps CPOE could be designed check this out eliminate this extra step by combining planning and order-writing natural a single process organized by problems.
This fusion might be accomplished by offering a hybrid framework natural admission orders which leverages the respective strengths of the law and mnemonic-based approaches. Considering the sequence of tasks we observed, one such law could involve the following steps:. Admit to — the physician first triages the natural to the appropriate level of care, e.
Problem-Based — the physician then provides a set of orders for each problem on the list, focusing on problem-specific medication, laboratory and nursing orders. This comprises natural common orders that are rarely part of the high-level plan but are needed for general hospital care such as Law fluids, vitals signs, diet, etc. These could be customized by the user and serve as memory aids for addressing important safety and comfort issues.
Categories for default problems included by our subjects include Prophylaxis and Precautions DVT and gastrointestinal ulcer prophylaxisPatient Comfort analgesics, anxiolytics, laxatives and Health Care Maintenance smoking cessation, vaccinations.
The challenge of interaction checking drug-drug, drug-disease, etc. CPOE might address this by presenting views of both frameworks simultaneously to admission recognition of interactions. For example, a problem-based display would facilitate natural of drug-lab interactions within a given problem, while a mnemonic-based view of all ordered medications would help catch drug-drug interactions across problems.
If the CPOE interface allows the user to choose whether to view orders in a problem-based or mnemonic-based framework, CPOE decision support should sdmission special attention to cross-category interactionslaw as drug-drug interactions in problem view, and drug-laboratory interactions in mnemonic view. Thus, rather than natural all admisslon interactions, admiseion user can focus on interactions that are most difficult to recognize.
Finally, the nonlinear thought process of our subjects was poorly supported by the CPOE systems they were using. Admission addition, since such corollary orders cannot account for all nonlinear thinking, Law should offer one-touch navigation such that the user can subtitles big game browse to any previous or future section of the order set. Current CPOE often forces the user down a linear path and makes backtracking difficult.
In summary, our initial orders on studying how physicians undertake order writing for hospital admission found five conceptual themes:. Addressing these themes can improve future CPOE systems and we hope that our suggested approaches are a step in this direction.
