Preventing failed appointments in general dental practice: a comparison of reminder methods.

OBJECTIVE: To test the effectiveness of different systems of reminding patients about their appointments in order to reduce the rate of failed attendance. The expense in implementing a reminder system for patients was also estimated. DESIGN: A clinical study in a single-handed dental practice. SUBJECTS: Patients were reminded about their appointment using either postal, manual telephone or automated telephone reminders (or all three combined). A control group received no reminders. 500 patient attendances were recorded in each group. RESULTS: Patients failed to attend for 130 of the 2500 appointments considered in the study. There was a significant reduction in the failed attendance rate from 9.4% (with no reminder) to a minimum of 3% when a reminder was given to the patient before the appointment. However, there was no significant difference among the four reminder test groups, indicating that the form of the reminder made no difference to the failure rate. CONCLUSIONS: Reminding patients using postal or manual telephone techniques is effective at improving attendance. All of the reminder methods, telephone and postal, provided net cost savings rather than additional costs.

Management of patients with diabetes through information technology: tools for monitoring and control of the patients' metabolic behavior.

BACKGROUND: The junction of telemedicine home monitoring with multifaceted disease management programs seems nowadays a promising direction to combine the need for an intensive approach to deal with diabetes and the pressure to contain the costs of the interventions. Several projects in the European Union and the United States are implementing information technology-based services for diabetes management using a comprehensive approach. Within these systems, the role of tools for data analysis and automatic reminder generation seems crucial to deal with the information overload that may result from large home monitoring programs. The objective of this study was to describe the automatic reminder generation system and the summary indicators used in a clinical center within the telemedicine project M2DM, funded by the European Commission, and to show their usage during a 7-month on-field testing period. METHODS: M2DM is a multi-access service for management of patients with diabetes. The basic functionality of the technical service includes a Web-based electronic medical record and messaging system, a computer telephony integration service, a smart-modem located at home, and a set of specialized software modules for automated data analysis. The information flow is regulated by a software scheduler, called the Organizer, that, on the basis of the knowledge on the health care organization, is able to automatically send e-mails and alerts notifications as well as to commit activities to software agents, such as data analysis. Thanks to this system, it was possible to define an automatic reminder system, which relies on a data analysis tool and on a number of technologies for communication. Within the M2DM system, we have also defined and implemented a number of indexes able to summarize the patients' day-by-day metabolic control. In particular, we have defined the global risk index (GRI) of developing microangiopathic complications. RESULTS: The system for generating automatic alarms and reminders coupled with the indexes for evaluating the patients' metabolic control has been used for 7 months at the Fondazione Salvatore Maugeri (FSM) in Pavia, Italy. Twenty-two patients (43 +/- 16 years old, 12 men and 10 women) have been involved; six dropped out from the study. The average number of monthly automatic messages was 29.44 +/- 9.83, i.e., about 1.8 messages per patient per month. The number of monthly alarm reminders generated by the system was 16.44 +/- 4.39, so that the number of alarms per patient was about 1. The number of messages sent by patients and physicians during the project was about 13 per month. The GRI analysis shows, during the last trimester, a slight improvement of the performance of the FSM clinic, with a decrease in the percentage of badly controlled values from 33% to 27%. Finally, we found the presence of a linear increasing correlation between the mean GRI values and the number of alarms generated by the system. CONCLUSIONS: A telemedicine system may incorporate features that make it a suitable technological backbone for implementing a disease management program. The availability of data analysis tools, automated messaging system, and summary indicators of the effectiveness of the health care program may help in defining efficient clinical interventions.

Patient reminder and patient recall systems to improve immunization rates.

BACKGROUND: Immunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result of low immunization rates, vaccine-preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care and large demands on primary care physicians, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. A common theme across immunization programs in all nations involves the challenge of determining the denominator of eligible recipients (e.g. all children who should receive the measles vaccine) and identifying the best strategy to ensure high vaccination rates. Strategies have focused on patient-oriented interventions (e.g., patient reminders), provider interventions and system interventions. One intervention strategy involves patient reminder and recall systems. OBJECTIVES: To assess the effectiveness of patient reminder and recall systems in improving immunization rates and compare the effects of various types of reminders in different settings or patient populations. SEARCH STRATEGY: A systematic search was performed for the initial review using MEDLINE (1966-1998) and four other bibliographic databases: EMBASE, PsychINFO, Sociological Abstracts, and CAB Abstracts. Authors also performed a search of The Effective Practice and Organisation of Care (EPOC) register in April 2001 to update the review. Two authors reviewed the lists of titles and abstracts and used the inclusion criteria to mark potentially relevant articles for full review. The reference lists of all relevant articles and reviews were back searched for additional studies. Publications of abstracts, proceedings from scientific meetings and files of study collaborators were also searched for references. In December 2004 the EPOC register was searched to identify relevant articles to update the review. SELECTION CRITERIA STUDY DESIGN: Randomized controlled trials (RCT), controlled before and after studies (CBA) and interrupted time series (ITS) studies written in English. TYPES OF PARTICIPANTS: Health care personnel who deliver immunizations and children (birth to 18 years) or adults (18 years and up) who receive immunizations in any setting. TYPES OF INTERVENTIONS: Any intervention that falls within the EPOC scope (See Group Details) and that includes patient reminder or recall systems, or both, in at least one arm of the study. TYPES OF OUTCOME MEASURES: Immunization rates or the proportion of the target population up-to-date on recommended immunizations. Outcomes were acceptable for either individual vaccinations (e.g. influenza vaccination) or standard combinations of recommended vaccinations (e.g. all recommended vaccinations by a specific date or age). DATA COLLECTION AND ANALYSIS DATA COLLECTION: Each study was read independently by two reviewers. Disagreements between reviewers were resolved by a formal reconciliation process to achieve consensus. ANALYSIS: Results are presented for individual studies as relative rates for randomized controlled trials and as absolute changes in percentage points for controlled before and after studies. Pooled results for RCTs only were presented using the random effects model. MAIN RESULTS: Five new studies were added for this update. Increases in immunization rates due to reminders were in the range of 1 to 20 percentage points. Reminders were effective for childhood vaccinations (OR = 1.45, 95% CI =1.28, 1.66), childhood influenza vaccinations (OR = 2.87, 95% CI = 1.65, 4.98), adult pneumococcus, tetanus, and Hepatitis B (OR = 2.19, 95% CI = 1.21, 3.99), and adult influenza vaccinations (OR = 1.66, 95% CI = 1.31, 2.09). All types of reminders were effective (postcards, letters, telephone or autodialer calls), with telephone being the most effective but most costly. AUTHORS' CONCLUSIONS: Patient reminder and recall systems in primary care settings are effective in improving immunization rates within developed countries.

Computerized decision support systems in primary care.

Computerized decision support can be passive or active. Passive decision support occurs when a computer facilitates access to relevant patient data or clinical knowledge for interpretation by the physician. Examples include CPR systems and reference texts or literature databases on CD-ROM. Effective passive decision support may ultimately prove to have a significant impact on physician decision making, but its potential to do so has been largely unexplored. Active decision support implies some higher level of information processing, or inference, by the computer. Examples include reminder / alert systems and diagnostic decision support systems. Inference processing in active decision support systems is generally rule-based, but probabilistic inference has been successfully used as well. Reminder systems have been consistently demonstrated to improve dramatically physician guideline compliance, generally by reducing oversight or error. The same potential for large-scale, systematic impact on physician decision-making by diagnostic decision support systems probably does not exist, but these systems may prove to be extremely useful in individual cases. Current applicability of diagnostic decision support systems to primary care is limited by the incompleteness and inaccuracies of the knowledge bases of these systems with respect to primary care. The applicability of computerized decision support in general to primary care is limited by more practical considerations. Widespread computerized decision support will not occur without CPR systems coupled with appropriate data standards and nomenclatures that will permit decision support tools to be accessed effortlessly during the routine process of patient care.

A computer-based maintenance reminder and record-keeping system for clinical laboratories.

"Maintenance" is all the activity an organization devotes to keeping instruments within performance specifications to assure accurate and precise operation. The increasing use of complex analytical instruments as "workhorses" in clinical laboratories requires more maintenance awareness by laboratory personnel. Record-keeping systems that document maintenance completion and that should prompt the continued performance of maintenance tasks have not kept up with instrumentation development. We report here a computer-based record-keeping and reminder system that lists weekly the maintenance items due for each work station in the laboratory, including the time required to complete each item. Written in BASIC, the system uses a DATABOSS data base management system running on a time-shared Digital Equipment Corporation PDP 11/60 computer with a RSTS V 7.0 operating system.

Improving timely surgical antibiotic prophylaxis redosing administration using computerized record prompts.

BACKGROUND: Timely prophylactic antibiotic administration aids in preventing postoperative superficial surgical site infections. However, during lengthy surgical procedures, redosing of prophylactic antibiotics may be unintentionally omitted. We assessed the utility of a computerized reminder as part of the anesthesia charting system to increase the rate of timely intraoperative prophylactic antibiotic redosing. METHODS: A retrospective observational analysis was performed on consecutive patients undergoing non-cardiac surgical procedures at a university-affiliated hospital prior to and after the institution of a computerized reminder system. The reminder system presented the clinician with a series of on-screen dialog boxes prior to the redose time for the specific prophylactic antibiotic administered preoperatively. Antibiotic redosing was defined as appropriate if it occurred within 30 min prior to or after the due time, calculated as twice the half-life of the specific antibiotic. Patients were excluded if the case duration was less than twice the half-life of the administered prophylactic antibiotic, or if no prophylactic antibiotic was given. RESULTS: A total of 287 cases were included in the study (148 pre-intervention, 139 post-intervention). Patient age, case length, and American Society of Anesthesiologists (ASA) score stratification did not differ between the groups. Use of the reminder system resulted in an increase in the appropriate redosing of antibiotics from 20% prior to institution of the reminder to 58% after institution (p < 0.001). CONCLUSIONS: A computerized reminder system is an effective tool to assist in appropriate intraoperative redosing of prophylactic antibiotics during lengthy surgical procedures.

Characteristics and consequences of drug allergy alert overrides in a computerized physician order entry system.

OBJECTIVE: The aim of this study was to determine characteristics of drug allergy alert overrides, assess how often they lead to preventable adverse drug events (ADEs), and suggest methods for improving the allergy-alerting system. DESIGN: Chart review was performed on a stratified random subset of all allergy alerts occurring during a 3-month period (August through October 2002) at a large academic hospital. MEASUREMENTS: Factors that were measured were drug/allergy combinations that triggered alerts, frequency of specific override reasons, characteristics of ADEs, and completeness of allergy documentation. RESULTS: A total of 6,182 (80%) of 7,761 alerts were overridden in 1,150 patients. In this sample, only 10% of alerts were triggered by an exact match between the drug ordered and allergy listed. Physicians' most common reasons for overriding alerts were "Aware/Will monitor" (55%), "Patient does not have this allergy/tolerates" (33%), and "Patient taking already" (10%). In a stratified random subset of 320 patients (28% of 1,150) on chart review, 19 (6%) experienced ADEs attributed to the overridden drug; of these, 9 (47%) were serious. None of the ADEs was considered preventable, because the overrides were deemed clinically justifiable. The degree of completeness of patients' allergy lists was highly variable and generally low in both paper charts and the CPOE system. CONCLUSION: Overrides of drug-allergy alerts were common and about 1 in 20 resulted in ADEs, but all of the overrides resulting in ADEs appeared clinically justifiable. The high rate of alert overrides was attributable to frequent nonexact match alerts and infrequent updating of allergy lists. Based on these findings, we have made specific recommendations for increasing the specificity of alerting and thereby improving the clinical utility of the drug allergy alerting system.

Practitioners' views on computerized drug-drug interaction alerts in the VA system.

OBJECTIVES: To assess Veterans Affairs (VA) prescribers' and pharmacists' opinions about computer-generated drug-drug interaction (DDI) alerts and obtain suggestions for improving DDI alerts. DESIGN: A mail survey of 725 prescribers and 142 pharmacists from seven VA medical centers across the United States. MEASUREMENTS: A questionnaire asked respondents about their sources of drug and DDI information, satisfaction with the combined inpatient and outpatient computerized prescriber order entry (CPOE) system, attitude toward DDI alerts, and suggestions for improving DDI alerts. RESULTS: The overall response rate was 40% (prescribers: 36%; pharmacists: 59%). Both prescribers and pharmacists indicated that the CPOE system had a neutral to positive impact on their jobs. DDI alerts were not viewed as a waste of time and the majority (61%) of prescribers felt that DDI alerts had increased their potential to prescribe safely. However, only 30% of prescribers felt DDI alerts provided them with what they needed most of the time. Both prescribers and pharmacists agreed that DDI alerts should be accompanied by management alternatives (73% and 82%, respectively) and more detailed information (65% and 89%, respectively). When asked about suggestions for improving DDI alerts, prescribers most preferred including management options whereas pharmacists most preferred making it more difficult to override lethal interactions. Prescribers and pharmacists reported primarily relying on electronic references for general drug information (62% and 55%, respectively) and DDI information (51% and 79%, respectively). CONCLUSION: Respondents reported neutral to positive views regarding the effect of CPOE on their jobs. Their opinions suggest DDI alerts are useful but still require additional work to increase their clinical utility.

A real-time, mobile phone-based telemedicine system to support young adults with type 1 diabetes.

Telemedicine systems have been proposed as a means of supporting people with diabetes in the self-management of their condition. Requirements for monitoring parameters of care, including glycaemic control, extent of analysis and interpretation of data, patient-clinician contacts, and involvement of a multidisciplinary care team with effective communication, can be addressed by telemedicine systems. We describe the development and implementation of an innovative real-time telemedicine system based around transmission and feedback of data to and from a mobile phone. Proprietary Java-based programs were used to link a blood glucose meter to a mobile phone. In addition to immediate transmission of blood glucose data, information about insulin dose, eating patterns and physical exercise were collected. Immediate feedback to the phone included a colour histogram to draw attention to levels of control over glycaemia over the previous two weeks. Clinicians supporting patients had access to summary screens identifying users not testing, and those with levels of blood glucose outside pre-defined limits. More detailed graphical displays of data were used to provide data about control of insulin dose and the degree to which it was modified in response to diet and exercise. The system has been evaluated in a clinical trial conducted in secondary care and is now being adapted for use in a trial in primary care, which is designed to assess its effectiveness in providing integrated management for the patient, general practitioner and pharmacist.

Using information technology to improve the health care of older adults.

The high burden of illness and frailty common among our growing population of older adults often results in fragmentation of care across providers and health care systems, increasing the complexity and costs of caring for these patients. Information technology offers one way to meet this challenge. Scientists at the Regenstrief Institute have more than a quarter-century of experience in using medical informatics to support clinicians in the day-to-day care of older adults. Their research has progressed through several evolutionary cycles, beginning with the acquisition of relevant data and moving to studies of the most efficient and effective mechanisms that bring information to bear at the time of clinical decision making. Information technology designed with the input of the end user has the greatest promise of changing provider behavior because it balances technological challenges with the cultural context of the practice environment. One topic of active research is information technology to support transitions of care among sites and providers. These transitions place older adults at increased risk for avoidable illness, death, and health care costs. Information systems that improve communication among providers during these transitions have the potential to improve safety and reduce costs.
