    Abstract

    Purpose: To compare a template-driven medical documentation system to undirected handwritten documentation and determine whether the template (1) decreases physician evaluation time, (2) increases gross billing, and (3) increases physician satisfaction with the documentation process.

    Methods: A prospective randomized trial of documentation with a template system (T-System for Primary Care, Dallas, TX) versus undirected handwritten documentation was conducted in 2 separate teams of a single family medicine residency program. After training, one team used the template system and the other team used undirected written documentation. Clinic visit duration was recorded. Medical records were evaluated by a blinded professional coder to assign an evaluation/management code. Clinic visit duration and coding level differences were evaluated using an independent t test. At the conclusion of the study, residents completed a questionnaire to determine physician satisfaction with the documentation tool. Survey responses were on a –2 to + 2 Likert scale. Means and standard deviations are reported.

    Results: A total of 1339 patients were included in the analysis of patient visits. There was no significant difference in clinic time between the template system and the written documentation visits. The mean visit time was 1.75 hours for both teams. For the analysis of gross billing, 1237 charts were included. The mean billing amount for written documentation was $150 and for the template system it was $163—a statistically significant difference. The physicians’ surveys favored continuing to use the template documentation method.

    Conclusions: The template medical documentation system compared with undirected written documentation produced a significantly higher bill for the visit, yielding no differences in evaluation time, and was overall positively received by the residents and faculty.

    Quality care depends on a clear and complete record, thus making medical documentation an intrinsic component of every patient encounter. There are many reasons to improve the quality of the medical record. Prior studies have suggested that the quality of documentation correlates with the quality of medical care.1,2 Quality improvement projects, research, and legal issues all rely on a complete accurate record. Coding, billing, and reimbursement depend on accurate documentation in specific areas. The process of recording a patient visit takes time, thereby affecting physician productivity and income. Time spent by physicians completing records can lengthen their day and create frustration. Family physicians use many different documentation methods today in their practices. These include undirected written charts, template-based written charts, dictation, and electronic medical records. Recent policies within the American Academy of Family Physicians, other medical specialty organizations, and from the federal government have called for a transition to an electronic medical record (EMR).3,4 Recent surveys estimate the usage of a full electronic medical record to be 15%. Cost and difficulty choosing an appropriate system are barriers to many physicians.5–7

    Research is needed to evaluate both EMR and other documentation methods. Results on paper documentation research may offer improvements applicable to many family medicine practices. Lessons learned evaluating paper documentation methods may translate to use on an EMR platform.

    The template system chosen for this study is T-System for Primary Care. It is a template-generated documentation system that was first designed for emergency care in 1996. Since then it has been used extensively across the United States. It is currently the documentation method for almost 40% of all emergency department (ED) visits in the United States and exists in both a paper and an integrated EMR format. The paper format was adapted to primary care in 2001 and is currently used by over a thousand providers. The cost of implementation is currently a $500 initial fee and then $2200 per year per provider. To study the effects of the template documentation system, we designed a prospective randomized controlled study. This study hypothesizes that the template system will (1) decrease physician evaluation time, (2) increase coding and reimbursement levels, and (3) improve physician satisfaction with the documentation record.

    Methods

    The study was performed in an inner city, county-owned, hospital-operated family medicine residency clinic. There are 2 separate teams that draw patients indiscriminately from the same undifferentiated patient population. The 2 teams are in separate but adjacent office space on the same floor of a professional office building. Both teams see equal volume. New patients are assigned to one of the 2 teams based on appointment availability. Thereafter patients are seen by the same team to which they were originally assigned. Residents are assigned to either team at the beginning of their residency and stay in that team through their 3 years of training. A total of 16 residents participated in either the template group or the control group. The clinic treats approximately 10,000 patients per year.

    One team was randomly chosen by coin toss to be the study team. The residents assigned to that team received a 1-hour training session on the template system from a company representative. All faculty physicians attended the training. The faculty worked in the same team for the duration of the study with few exceptions. Nurses and medical assistants attended the same training session because they are rotated between teams. The templates were used approximately 6 weeks before the start of data collection.

    Three template systems were reviewed before selecting one for use in the study. The selected system was chosen because of higher volume of use and greater customer support. For examples of this template system, please visit http://www.tsystem.com/Template-Systems/primary-care.asp. The template system we used is a series of 40 templates based on chief complaint. Each template includes specific symptoms based on the chief complaint(s). Additional complaints are addressed in a small narrative section. By a series of circles, checks, and backslashes the physician documents the presence or absence of each finding. A tailored review of systems is provided, and there are areas for past medical/social/family history. Relevant physical findings are listed on the template, and they are checked or backslashed to denote the presence or absence. Each of the above sections includes some blank lines for additional information. Shaded areas denote information required for higher levels of service.

    There were 2 primary outcomes measured: time of physician evaluation and billing amount. A secondary outcome was physician satisfaction. Physician evaluation time was calculated using the time the patient was placed in the room and the clinic discharge time. A power analysis indicated that a sample size of 650 patients per team had 88% power to detect a 7-minute reduction in time (a clinically relevant number). Based on current clinic volume, a study period of 6 weeks was chosen.

    To analyze billing amount, an independent trained and certified coder was hired to determine the billing amounts for all patient visits included in the study. The 1995 Health Care Financing Administration (HCFA) guidelines were used. These guidelines are often used in practice because they are less complex than a 1997 revision. The coder was given no details regarding the nature of the study nor was he shown the actual codes assigned by the family medicine department. Based on the previously published results, a sample size of 650 has a power of 80% to detect a 19% billing increase (an effect size of 0.16).

    Both physician evaluation and billing amount were checked for normality and outliers. An independent t test was used to compare both the average examination room time of the 2 teams and the average billing amount across the 2 teams.

    At the conclusion of the study a survey was given to the residents of the team using the template to measure physician satisfaction. Permission to use the survey tool was granted by the American College of Emergency Physicians and had been used in a previous study.8 Ten questions were administered using a 5-point Likert scale, with responses ranging from strongly disagree to strongly agree. A set of 3 different questions was asked of the faculty physicians using the same Likert scale. The mean response was calculated. Because this is an unvalidated opinion survey, the comparative analysis was considered secondary, and power was not determined a priori.

    All analyses and graphs were performed on SPSS 12.0 (SPSS Inc., Chicago, IL). Institutional Review Board permission was granted before onset of data collection.

    Results

    The control team included 626 patient visits with a mean billing amount of $149.63 (95% CI, 145.8 to 153.5), whereas the template team included 611 patient visits with a mean billing amount of $163.38 (95% CI, 159.0 to 167.7). The gross difference is $13.75 (95% CI, 8.0 to 19.5). An independent t test indicates that the gross billing amount is statistically significant across the 2 teams for the independent blinded standard coder (t = 4.67, df = 1235) (Figure 1). Table 1 shows the frequency for common billing codes by team. The 2 teams saw a total of 1339 patients over the specified time period. Of these, 1237 patient records were sent to the independent coder. That indicates that 102 medical records were lost to coding. Because of blinding, we were unable to determine which patients were missing the coder information, but the loss was equally distributed across the 2 teams.

    Patient visit time, based on time in room to discharge time, showed no significant difference between the control and template team. There were 694 patients in the control team and 645 patients in the template team. The mean visit time was 1.75 hours for both teams (95% CI about the zero difference is –0.65 to +0.65) (Figure 2).

    The data for each survey item is displayed in Table 2 for faculty and in Table 3 for residents. Question 1 of the faculty survey was an overall question relating to the continued use of the template system. The average score from the faculty was 1.0 on a scale from –2 to +2, where –2 indicates a response of strongly disagree and +2 indicates a strongly agree response. Question 10 of the resident survey was also a question on continuing the use of the template, and the average response was 0.5 on the same scale.

    Conclusions

    We chose to study a paper-based documentation method for many reasons. Our institution is not ready to implement electronic medical records in the family medicine residency clinic. The main barrier is cost. Although EMR will probably be adopted sometime, there is no specific target date, and we wanted to improve our documentation method now. A template-driven medical documentation system is an available product with a reasonable start up cost, and minimal training time is required. Template systems specifically include issues relevant to the chief complaint. They can remind physicians to inquire about and document important aspects of the visit. This can be an advantage, especially in a training environment. Conversely, a template is a structured format that cannot include all variables in treating a patient.

    We chose to measure the time the patient was placed in the room until the patient was discharged to represent the clinic visit time. This time was measurable in a reliable way in our clinic, yet included many variables other than the physician encounter. Our data showed no significant difference in clinic times between the 2 teams. This demonstrates that the template system can be adopted with minimal training time (1 hour) and neither adversely affects nor improves productivity.

    The coding levels shown are representative of our experience in an inner city, county hospital clinic (no lower level new patient codes—99201, 99202). There are few simple visits for new patients; they often present with a list of complaints. In addition there were few high level codes for new patients (99205). Higher level of service is more difficult to deliver and document in new patients because documentation guidelines for new patients are more extensive at the higher level of service.

    Regarding the coding data, there was significant improvement in overall billing in the team using the template system. The HCFA guidelines are a complex set of directives regarding required documentation for each evaluation and management code. Prior studies have determined that both under and over coding are common errors using these guidelines.7,8 In addition, expert coders frequently do not agree when assigning a level of service.8 This is worrisome because an accusation that a physician is coding improperly can lead to audits and penalties. Complete records with required documentation should yield better billing data by preventing both internal and payer down coding. The mean professional bill was $162 for the template team and $149 for the undirected charting groups, using the 1995 HCFA Guidelines.

    Physician satisfaction survey results show that both residents and faculty physicians involved in the study slightly favored using the template system. These results are supported by a prior study that measured satisfaction with the template in the ED 1 month and 1 year after implementation. This prior study found that satisfaction was weakly positive initially and further improved with continued use of the product.9 Further studies should address how continued use of the product affects satisfaction in the family medicine setting. In addition, physicians refer back to prior documented visits during patient follow-up. Physician satisfaction with a template system for this purpose should be studied.

    The results of our study are consistent with a similar study within an emergency medicine setting.8 The Emergency Medicine Study also used the T-System and showed improved billing but a nonstatistically insignificant decrease in patient visit time. Physician satisfaction in the Emergency Medicine Study was higher than in our setting when measured after a longer period of use.

    There are several limitations to this study and areas for further study. Both residents and faculty perceived the template documentation as slightly faster. Studying the exact time of physician evaluation rather than total patient visit time might detect a difference between the template system and the undirected format. Speed with the product might improve with continued use so repeating the measurements after longer exposure to the template might yield greater differences.

    A further limitation of our study is that it did not index diagnoses or patient complaints. We assumed similar levels of complexity of care because new patients are assigned to either of the 2 teams and subsequently followed in the same team.

    This study compared a template-driven medical documentation system to undirected written documentation. Further studies should compare template systems to other types of documentation methods including EMR. Both the residents and faculty are salaried without productivity incentives. There was no financial incentive for them to improve patient billing data. This may affect their satisfaction with the product. Studying a template-driven documentation system in a family medicine setting where billing data affects physician reimbursement might yield improved satisfaction data.

    This study looked at billing data but not reimbursement. Further study of charting methods should analyze the actual money generated related to improved billing data. A shift to billing at a higher level requires consideration of additional compliance issues. Medicare patients seen by family medicine residents must also be seen and examined by an attending physician for 99214 and 99215 levels of service.9 Local practices may require changes to policy with additional surveillance that may affect the overall generated revenue.

    This study focused on billing data, clinic visit time, and physician satisfaction. Further studies on medical documentation should include patient-oriented outcomes. These would include effects on patient satisfaction and on the patient-physician interaction.

    The challenge of finding optimal documentation tools will continue in medicine. This study compared a template-driven medical documentation system to undirected written documentation in a family medicine residency clinic. The template system was preferred by the physicians, did not affect clinic times, and improved billing data. On study completion, we chose to implement the use of the template system throughout our clinic.
