Internally developed medical equipment management system: a viable alternative.

A medical equipment management computer system, internally developed by Rhode Island Hospital, is presented. Hospital biomedical engineering departments must contend with ever-increasing regulatory requirements for patient-care equipment. Computerization is a viable solution to meeting the documentation standards dictated by healthcare governing bodies. Rhode Island Hospital's system consists of a Macintosh computer, Panorama database software, and Psion LZ64 Organiser handheld computer. Files were set up on equipment data, JCAHO-required historical documentation, service, inspections, part codes and locations, and vendor contact information. Technician inspection data recording time was reduced by approximately 30%.

What explains doctors' usage of Mobile Information and Communication Technologies? A comparison of US and Portuguese hospitals.

Doctors, either as a result of individual initiative or departmental policy, may use a number of different mobile computers. The relationship between device ownership/provision and usage is, however, rarely discussed. This paper therefore presents survey data (N=267) on mobile computer ownership and use by doctors in two Portuguese and two US hospitals, considering both devices owned by individuals and those supplied by the hospital. The results show that ownership is not clearly related to either usage pattern or frequency of use. Providing handheld computers also did not lead to higher number of users, higher frequency of use or significant differences in tasks carried out. Nevertheless, doctors owning handhelds alone or in combination with laptops used them more frequently than those using laptops alone. Differences in usage pattern proportions rather than demographics were a better indication of differences in usage frequencies and the tasks for which MICT devices were being used.

Basic microbiologic and infection control information to reduce the potential transmission of pathogens to patients via computer hardware.

Computer technology from the management of individual patient medical records to the tracking of epidemiologic trends has become an essential part of all aspects of modern medicine. Consequently, computers, including bedside components, point-of-care testing equipment, and handheld computer devices, are increasingly present in patients' rooms. Recent articles have indicated that computer hardware, just as other medical equipment, may act as a reservoir for microorganisms and contribute to the transfer of pathogens to patients. This article presents basic microbiological concepts relative to infection, reviews the present literature concerning possible links between computer contamination and nosocomial colonizations and infections, discusses basic principles for the control of contamination, and provides guidelines for reducing the risk of transfer of microorganisms to susceptible patient populations.

Mobile computing in the humanitarian assistance setting: an introduction and some first steps.

We developed a Palm operating system-based handheld computer system for admin istering nutrition questionnaires and used it to gather nutritional information among the Burmese refugees in the Mae La refugee camp on the Thai-Burma border Our experience demonstrated that such technology can be easily adapted for such an austere setting and used to great advantage. Further, the technology showed tremendous potential to reduce both time required and errors commonly encountered when field staff collect information in the humanitarian setting. We also identified several areas needing further development.

Family physicians' preferences for computerized decision-support hardware and software.

BACKGROUND: While computers are now widely used by family physicians for billing and patient registration purposes, their use as decision-support tools is still quite limited. The purpose of this study was to determine the current use of computer hardware and software by family physicians, and the characteristics these physicians desire in computerized decision-support hardware and software. METHODS: A cross-sectional survey of a random sample of 250 Michigan family physicians was undertaken in mid-1995. These physicians were asked about their current use of a variety of computer hardware and software. They were also asked to rate the value of different kinds of decision-support information potentially available by computer. The survey instrument also gathered the family physicians' preferences for design factors (both hardware and software), such as the size of a computer, the time needed to access information, and the frequency of updates. RESULTS: Word processing on desktop computers and hospital information systems are the most widely used computer applications by family physicians. Physicians are most interested in computer-based information on drugs, storage and generation of patient education materials, and accessing treatment recommendations. Most feel that semiannual or annual updates of information are adequate, and would like a uniform interface. A high percentage of physicians (84.5% of all physicians and 94.1% of younger physicians) stated that they would consider carrying a handheld computer. CONCLUSIONS: There is significant interest in several types of clinical decision-support software. Based on the results of this study, such software should have following characteristics: (1) be available for handheld as well as networked and desktop computers, (2) include drug information (particularly warnings, interactions, and side effects), (3) include overviews of treatment recommendations, (4) include patient education materials, and (5) have a uniform user interface and be updated at least annually.

Utility of palmtop computers in a residency program: a pilot study.

BACKGROUND: With advancing technology and flourishing medical information on the Internet, we studied the use of palmtop (handheld) computers by internal medicine residents. METHODS: At a university-community hospital consortium, nine internal medicine residents and their program director participated in an 8-month cohort pilot study using palmtop computers with desktop synchronization and Internet access capabilities. RESULTS: After 2 months of use, the residents had found a variety of uses for palmtop computers, such as the calendar, downloading residency-provided medical information, taking lecture notes, using a spreadsheet for common formulas, Internet/MEDLINE searching with modem access, infrared file transfer, downloading call schedules, and patient tracking. At 8 months, the residents were comfortable using palmtops on a daily basis. Technical difficulties included cumbersome modem cords, incompatible platforms and difficult Internet access at times, finding analog telephone lines in the hospital, and synchronization with home computers. CONCLUSION: Palmtop computers are useful in the residency setting, and residents are capable of devising ways to use palmtops to suit their individual needs.

Pharmacist computer skills and needs assessment survey.

BACKGROUND: To use technology effectively for the advancement of patient care, pharmacists must possess a variety of computer skills. We recently introduced a novel applied informatics program in this Canadian hospital clinical service unit to enhance the informatics skills of our members. OBJECTIVE: This study was conducted to gain a better understanding of the baseline computer skills and needs of our hospital pharmacists immediately prior to the implementation of an applied informatics program. METHODS: In May 2001, an 84-question written survey was distributed by mail to 106 practicing hospital pharmacists in our multi-site, 1500-bed, acute-adult-tertiary care Canadian teaching hospital in Vancouver, British Columbia. RESULTS: Fifty-eight surveys (55% of total) were returned within the two-week study period. The survey responses reflected the opinions of licensed BSc and PharmD hospital pharmacists with a broad range of pharmacy practice experience. Most respondents had home access to personal computers, and regularly used computers in the work environment for drug distribution, information management, and communication purposes. Few respondents reported experience with handheld computers. Software use experience varied according to application. Although patient-care information software and e-mail were commonly used, experience with spreadsheet, statistical, and presentation software was negligible. The respondents were familiar with Internet search engines, and these were reported to be the most common method of seeking clinical information online. Although many respondents rated themselves as being generally computer literate and not particularly anxious about using computers, the majority believed they required more training to reach their desired level of computer literacy. Lack of familiarity with computer-related terms was prevalent. Self-reported basic computer skill was typically at a moderate level, and varied depending on the task. Specifically, respondents rated their ability to manipulate files, use software help features, and install software as low, but rated their ability to access and navigate the Internet as high. Respondents were generally aware of what online resources were available to them and Clinical Pharmacology was the most commonly employed reference. In terms of anticipated needs, most pharmacists believed they needed to upgrade their computer skills. Medical database and Internet searching skills were identified as those in greatest need of improvement. CONCLUSIONS: Most pharmacists believed they needed to upgrade their computer skills. Medical database and Internet searching skills were identified as those in greatest need of improvement for the purposes of improving practice effectiveness.

Barriers to rural physician use of a digital health sciences library.

BACKGROUND: Rural physicians need access to quality medical information, but accessing information is difficult in rural settings. Digital health sciences libraries (DHSLs) offer the potential to make information more accessible to rural physicians. A telemedicine network was deployed to six rural hospitals in Iowa. Computers were installed allowing access to a DHSL and training sessions were held. The purpose of this study was to examine the barriers to use of a DHSL by rural physicians. METHODS: Approximately one year after deployment of the telemedicine network, physicians were surveyed using a modified critical incident technique. RESULTS: Seventy percent of the eligible physicians responded and 33% had used the DHSL. Primary barriers included insufficient training, being too time consuming to use, and distance of computers from physicians' practice sites. Non-DHSL users cited the difficulty of using the DHSL as their greatest barrier, while DHSL users cited the quality of the information resources. CONCLUSIONS: This study identifies a number of barriers that exist to rural physicians use of a DHSL. Potential solutions to these barriers are discussed. DHSLs will finally reach their potential when they can be delivered by easy to use handheld computers seamlessly integrated into the rural physician's workflow.

Hypoglycemia and the decision to drive a motor vehicle by persons with diabetes.

CONTEXT: Laboratory studies have shown impairments in driving performance among subjects with type 1 diabetes mellitus when their blood glucose (BG) level is between 2.6 and 3.6 mmol/L (47-65 mg/dL). However, to our knowledge, no data exist examining subjects' decisions to drive at various BG levels during their daily routine. OBJECTIVE: To examine type 1 diabetic subjects' decisions to drive during their daily routine based on perception of BG levels compared with actual measured BG levels. DESIGN AND SETTING: Two separate groups of patients were recruited 2 years apart from 4 academic medical centers. PARTICIPANTS: All subjects were adults with type 1 diabetes who were drivers and who performed at least 2 BG tests per day. Group 1 (initial) subjects (n = 65) had a mean (SD) age of 38.6 (8.9) years with a mean (SD) diabetes duration of 20.5 (10.6) years, were taking 38.8 (16.8) U/d of insulin, and had a mean (SD) glycosylated hemoglobin (HbA1) level of 10.0% (1.9%). Group 2 (replication) subjects (n = 93) were 35.8 (8.0) years old with a mean diabetes duration of 17.0 (10.6) years, were taking 40.0 (15.5) U/d of insulin, and had a mean (SD) HbA1 level of 8.5% (1.6%). Each subject used a handheld computer to record data on symptoms, cognitive function, insulin dosage, food, activity, estimated and actual BG levels, and whether he/she would drive. Data were entered 3 to 6 times per day for a total of 50 to 70 collections per subject during a 3- to 4-week period. MAIN OUTCOME MEASURES: Decisions to drive when subjects estimated their BG level to be less than 2.2 mmol/L (40 mg/dL), 2.2 to 2.8 mmol/L (40-50 mg/dL), 2.8 to 3.3 mmol/L (50-60 mg/dL), 3.3 to 3.9 mmol/L (60-70 mg/dL), 3.9 to 10 mmol/L (70-180 mg/dL), and more than 10 mmol/L (>180 mg/dL), and driving decisions when actual BG levels were in these ranges. RESULTS: Subjects stated they would drive 43% to 44% of the time when they estimated their BG level to be 3.3 to 3.9 mmol/L (60-70 mg/dL), and 38% to 47% of the time when their actual BG level was less than 2.2 mmol/L (40 mg/dL). Logistic regression analysis demonstrated that number of autonomic symptoms, degree of impairment on cognitive function tests, and BG level estimate predicted 76% to 80% of decisions to drive (P<.01 for all). Approximately 50% of subjects in each group decided to drive at least 50% of the time when their BG level was less than 3.9 mmol/L (70 mg/dL). CONCLUSIONS: Our data suggest that persons with type 1 diabetes may not judge correctly when their BG level is too low to permit safe driving and may consider driving with a low BG level even when they are aware of the low level. Health care professionals should counsel their patients about the risk of driving with hypoglycemia and the importance of measuring BG level before driving.

Clinical decision support and appropriateness of antimicrobial prescribing: a randomized trial.

CONTEXT: The impact of clinical decision support systems (CDSS) on antimicrobial prescribing in ambulatory settings has not previously been evaluated. OBJECTIVE: To measure the added value of CDSS when coupled with a community intervention to reduce inappropriate prescribing of antimicrobial drugs for acute respiratory tract infections. DESIGN, PARTICIPANTS AND SETTING: Cluster randomized trial that included 407,460 inhabitants and 334 primary care clinicians in 12 rural communities in Utah and Idaho (6 with 1 shared characteristic and 6 with another), and a third group of 6 communities that served as nonstudy controls. The preintervention period was January to December 2001 and the postintervention period was January 2002 to September 2003. Acute respiratory tract infection diagnoses were classified into groups based on indication for antimicrobial use. Multilevel regression methods were applied to account for the clustered design. INTERVENTION: Six communities received a community intervention alone and 6 communities received community intervention plus CDSS that were targeted toward primary care clinicians. The CDSS comprised decision support tools on paper and a handheld computer to guide diagnosis and management of acute respiratory tract infection. MAIN OUTCOME MEASURE: Community-wide antimicrobial usage was assessed using retail pharmacy data. Diagnosis-specific antimicrobial use was compared by chart review. RESULTS: Within CDSS communities, 71% of primary care clinicians participated in the use of CDSS. The prescribing rate decreased from 84.1 to 75.3 per 100 person-years in the CDSS arm vs 84.3 to 85.2 in community intervention alone, and remained stable in the other communities (P = .03). A total of 13,081 acute respiratory tract infection visits were abstracted. The relative decrease in antimicrobial prescribing for visits in the antibiotics "never-indicated" category during the post-intervention period was 32% in CDSS communities and 5% in community intervention-alone communities (P = .03). Use of macrolides decreased significantly in CDSS communities but not in community intervention-alone communities. CONCLUSION: CDSS implemented in rural primary care settings reduced overall antimicrobial use and improved appropriateness of antimicrobial selection for acute respiratory tract infections. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00235703.

Mental health problems among adults in tsunami-affected areas in southern Thailand.

CONTEXT: On December 26, 2004, an undersea earthquake occurred off the northwestern coast of Sumatra, Indonesia. The tsunami that followed severely affected all 6 southwestern provinces of Thailand, where 5395 individuals died, 2991 were unaccounted for, and 8457 were injured. OBJECTIVE: To assess the prevalence of symptoms of posttraumatic stress disorder (PTSD), anxiety, and depression among individuals residing in areas affected by the tsunami in southern Thailand as part of a public health emergency response and rapid assessment. DESIGN, SETTING, AND PARTICIPANTS: A multistage, cluster, population-based mental health survey was conducted from February 15 to 22, 2005, of random samples of displaced (n = 371) and nondisplaced persons in Phang Nga province (n = 322) and nondisplaced persons in the provinces of Krabi and Phuket (n = 368). Data were collected using an interviewer-administered questionnaire on handheld computers. A surveillance follow-up survey of the displaced persons (n = 371) and nondisplaced persons (n = 322) in Phang Na was conducted in September 2005. MAIN OUTCOMES MEASURES: Medical Outcomes Study-36 Short-Form Health Survey SF-36 to assess self-perceived general health, bodily pain, and social and emotional functioning; the Harvard Trauma Questionnaire to assess tsunami-specific traumatic events; and the Hopkins Checklist-25 to detect symptoms of anxiety and depression. RESULTS: Participation rates for displaced and nondisplaced persons in the rapid assessment survey were 69% and 58%, respectively. Symptoms of PTSD were reported by 12% of displaced and 7% of nondisplaced persons in Phang Nga and 3% of nondisplaced persons in Krabi and Phuket. Anxiety symptoms were reported by 37% of displaced and 30% of nondisplaced persons in Phang Nga and 22% of nondisplaced persons in Krabi and Phuket. Symptoms of depression were reported by 30% of displaced and 21% of nondisplaced persons in Phang Nga and 10% of nondisplaced persons in Krabi and Phuket. In multivariate analysis, loss of livelihood was independently and significantly associated with symptoms of all 3 mental health outcomes (PTSD, anxiety, and depression). In the 9-month follow-up surveillance survey of 270 (73%) displaced and 250 (80%) nondisplaced participants in Phang Nga, prevalence rates of symptoms of PTSD, anxiety, and depression among displaced persons decreased to 7%, 24.8%, and 16.7%, respectively, and among nondisplaced persons, prevalence rates decreased to 2.3%, 25.9%, and 14.3%, respectively. CONCLUSIONS: Among survivors of the tsunami in southern Thailand, elevated rates of symptoms of PTSD, anxiety, and depression were reported 8 weeks after the disaster, with higher rates for anxiety and depression than PTSD symptoms. Nine months after the disaster, the rates of those reporting these symptoms decreased but were still elevated. This information is important for directing, strengthening, and evaluating posttsunami mental health needs and interventions.

An evaluation of the relationship between mood and binge eating in the natural environment using ecological momentary assessment.

OBJECTIVE: Although many current theories of disordered eating focus on affective mechanisms, relatively little is known about the covariation of mood and eating in peoples' natural environments. This study examined the relationship between mood and binge eating behavior in the natural environment. METHOD: Twenty-seven college students with subclinical binge eating behavior self-monitored their mood on a handheld computer seven times daily for 2 weeks. RESULTS: On binge days, participants reported having significantly worse mood than on nonbinge days. When the trajectory of mood around the time of a binge was examined, no significant differences between prebinge and postbinge time were found when the entire binge day was examined. No mood differences were found between just prior to the binge (30-60 min prior to binge) compared with just after the binge (also within 30-60 min). A postbinge report indicated that reported mood immediately after a binge was worse than mood just prior to the binge. DISCUSSION: This study provides evidence that the affective experience of binge eating, when assessed in the natural environment, is negative. Furthermore, there was no evidence that binge eating was a response to an immediate or transient negative mood state or that binge eating provided relief from negative mood.

The impact of future trends in electronic data collection on musculoskeletal research and evidence-based orthopaedic care.

Electronic medical documentation systems offer the greatest potential source of data to enable the evolution to evidence-based musculoskeletal care. To this end, it is important that providers of musculoskeletal care embrace structured medical records systems that record medical information in fields thereby making data easily accessible for the purpose of later analysis. Gathering data in a structured format can be labor intensive but significant time and cost savings are realized by reduced dictation and transcription and the automated output of requisitions and correspondence. Physicians will only use structured electronic records if the system reduces overhead while at the same time minimizing their work load. Since getting information into the system is the greatest impediment to successful implementation of a structured record, the use of Web forms for previsit patient data entry and touch screen handheld computers with wireless connectivity for provider data entry will play an important role in facilitating their adoption. Ultimately, industry-standard, field-naming nomenclature for specific historical features, examination findings, and therapeutic interventions will make data in all documentation systems comparable regardless of vendor. When that day comes, every new patient assessed will be a candidate for a prospective study.

The story behind the story: physician skepticism about relying on clinical information technologies to reduce medical errors.

PURPOSE: In order to better understand physicians' perspectives about the use of clinical information technology (CIT) to reduce medical errors, we asked physicians about opportunities and issues around clinical use of computerized physician order entry (CPOE) systems, order sets within CPOE, and handheld computers (HHCs). METHODS: We conducted 10 focus groups including 71 physicians involved in technology implementation efforts across the US between April 2002 and February 2005. RESULTS: Two major themes emerged across focus groups around reliance on CIT to reduce errors: (1) can it work? and (2) at what cost to the medical profession? Within the first theme, physicians expressed concern about the appropriateness of physician-directed CIT as a solution for medical errors, concerns regarding the current technical capabilities and level of technical support for CIT solutions, and concern about the introduction of new errors. Within the second theme, physicians were particularly concerned about time efficiency and workload redistribution associated with the introduction of CIT. Across focus groups, physicians tended to generalize about the role of all IT in their lives, potentially biasing opinions about specific technologies. CONCLUSIONS: Health care organizations attempting to promote physician use of CIT are advised to deepen consideration of physicians' perspectives about technology adoption and use in order to address their concerns, reduce skepticism, and increase the likelihood of implementation success.

Computerized experience sampling method (ESMc): assessing feasibility and validity among individuals with schizophrenia.

The Experience Sampling Method (ESM) is an ecologically valid, time-sampling of self-reports developed to study the dynamic process of person-environment interactions. ESM with digital wristwatch and booklets (paper-based ESM; ESMp) has been used extensively to study schizophrenia. The present study is designed to test the feasibility and validity of using Computerized ESM (ESMc) among individuals with schizophrenia. ESMc is advantageous in allowing for recording of precise time-stamps of responses. We used PDAs ("Personal Digital Assistant"; Palm handheld computers) to collect data on momentary psychotic symptoms, mood, and thoughts over a one day period among 10 hospitalized schizophrenia patients and 10 healthy controls. ESMc was equally acceptable to both groups, with similar ratings of comfort carrying the PDAs and operating them, interference with daily activities, as well as response rates. The schizophrenia patients reported significantly higher ratings of auditory and visual hallucinations, suspiciousness, sense of unreality, lack of thought control, fear of losing control, difficulty expressing thoughts, as well as depression/sadness, loneliness and less cheerfulness. Significant inverse relationships were found among both groups between ratings of feeling cheerful and being stressed, irritated, and sad/depressed. Among the schizophrenia subjects, the correlation between ratings of suspiciousness on ESMc and Scale for Assessment of Positive Symptoms (SAPS) approached significance, as well as the link between suspiciousness and stress. Our results support the feasibility and validity of using ESMc for assessment of momentary psychotic symptoms, mood, and experiences among individuals with schizophrenia. The authors discuss the potential applications of combining ESMc with ambulatory physiological measures.

A randomized trial of electronic versus paper pain diaries in children: impact on compliance, accuracy, and acceptability.

Electronic diary assessment of pain and disability has become increasingly popular in adult chronic pain research but use of this methodology with children has received limited attention. The aim of this study was to compare two formats of a prospective daily diary (handheld computer=e-diary; paper diary=p-diary) on children's compliance, accuracy, and acceptability ratings. Sixty children, ages 8-16 (M=12.3) with headaches or juvenile idiopathic arthritis, were randomized to receive either e-diaries administered via home visits (n=30) or p-diaries (n=30) handed out during clinic visits for return by mail. Results demonstrated significant mean differences in diary entries completed between groups, with children with e-diaries completing more days (M=6.6) compared to children with p-diaries (M=3.8), P<0.001. Diaries returned by children in the p-diary group contained significantly more errors and omissions compared to diaries returned by children in the e-diary group (which contained none), P<0.001. Children rated both diary formats as highly acceptable and easy to use. A significant gender x diary format interaction (P<0.01) was found for compliance where boys demonstrated greater compliance with the e-diary format. Findings demonstrated that the e-diary was feasible to use with children and showed significantly greater compliance and accuracy in diary recording compared to traditional paper diaries in a population of children with recurrent pain.

Trait anxiety moderates the impact of performance pressure on salivary cortisol in everyday life.

Stress and negative affective states are associated with cortisol in everyday life. However, it remains unclear what types of stressors and which affective states yield these associations, and the effect of trait anxiety is unknown. This study investigates the associations of specific task-related stressors and negative affective states in everyday life with salivary cortisol, and explores the mediating and moderating role of state negative affect and trait anxiety, respectively. Salivary cortisol, subjective stress, and state negative affect were measured three times a day on 2 days in 71 participants in everyday life, using a handheld computer to collect self-reports and time stamps and an electronic device to monitor saliva sampling compliance. Stress measures comprised the experience of performance pressure and failure during daily tasks; measures of negative affect comprised worn-out, tense, unhappy, and angry. Effects were tested using multilevel fixed-occasion models. Momentary performance under pressure was related to higher momentary cortisol measures, while mean task failure was related to lower daily cortisol concentrations. The association of performance pressure with cortisol varied between subjects, and this variation was explained by trait anxiety, yielding stronger associations in participants scoring high on trait anxiety. No evidence was found for a mediating role of state negative affect. These results describe the well-documented associations of everyday stressors and affect with salivary cortisol more precisely, suggesting that performance pressure is a significant condition related to short-term changes in cortisol. Subjects scoring high on trait anxiety seem to process stress-relevant information in a way that amplifies the association of performance pressure with reactions of the hypothalamus-pituitary-adrenal axis.
