Informatics in Primary Care最新文献

Background: In primary care settings, users often rely on vendors to provide support for health information technology (HIT). Yet, little is known about the vendors' perspectives on the support they provide, how support personnel perceive their roles, the challenges they face and the ways they deal with them.

Objective: To provide in-depth insight into an electronic medical record (EMR) vendor's perspective on end-user support.

Methods: As part of a larger case study research, we conducted nine semi-structured interviews with help desk staff, trainers and service managers of an EMR vendor, and observed two training sessions of a new client.

Results: With a growing client base, the vendor faced challenges of support staff shortage and high variance in users' technical knowledge. Additionally, users sometimes needed assistance with infrastructure, and not just software problems. These challenges sometimes hindered the provision of timely support and required supporters to possess good interpersonal skills and adapt to diverse client population.

Conclusion: This study highlights the complexity of providing end-user support for HIT. With increased adoption, other vendors are likely to face similar challenges. To deal with these issues, supporters need not only strong technical knowledge of the systems, but also good interpersonal communication skills. Some responsibilities may be delegated to super-users. Users may find it useful to hire local IT staff, at least on an on-call basis, to provide assistance with infrastructure problems, which are not supported by the software vendor. Vendors may consider expanding their service packages to cover these elements.

Background: The internet can provide evidence-based patient education to overcome time constraints of busy ambulatory practices. Health information prescriptions (HIPs) can be effectively integrated into clinic workflow, but compliance to visit health information sites such as MedlinePlus is limited.

Objective: Compare the efficacy of paper (pHIP) and email (eHIP) links to deliver HIPs; evaluate patient satisfaction with the HIP process and MedlinePlus information; assess reasons for noncompliance to HIPs.

Method: Of 948 patients approached at two internal medicine clinics affiliated with an academic medical centre, 592 gave informed consent after meeting the inclusion criteria. In this randomised controlled trial, subjects were randomised to receive pHIP or eHIP for accessing an intermediate website that provided up to five MedlinePlus links for physician-selected HIP conditions. Patients accessing the intermediate website were surveyed by email to assess satisfaction with the health information. Survey non-responders were contacted by telephone to determine the reasons for no response.

Results: One hundred and eighty-one patients accessed the website, with significantly more 'filling' eHIP than pHIP (38% vs 23%; P < 0.001). Most (82%) survey respondents found the website information useful, with 77% favouring email for future HIPs delivery. Lack of time, forgot, lost instructions or changed mind were reasons given for not accessing the websites.

Conclusions: Delivery of MedlinePlus-based HIPs in clinic is more effective using email prescriptions than paper. Satisfaction with the HIP information was high, but overall response was low and deserves further investigation to improve compliance and related outcomes.

Background: Major initiatives are underway in Canada which are designed to increase electronic medical record (EMR) implementation and maximise its use in primary health care. These developments need to be supported by sufficient evidence from the literature, particularly relevant research conducted in the Canadian context.

Objectives: This study sought to quantify this lack of research by: (1) identifying and describing the primary health care EMR literature; and (2) comparing the Canadian and international primary healthcare EMR literature on the basis of content and publication levels.

Methods: Seven bibliographic databases were searched using primary health care and EMR keywords. Publication abstracts were reviewed and categorised. First author affiliation was used to identify country of origin. Proportions of Canadian- and non-Canadian-authored publications were compared using Fisher's exact test. For countries having 10 or more primary healthcare EMR publications, publications per 10 000 researchers were calculated.

Results: After exclusions, 750 publications were identified. More than one-third used primary healthcare EMRs as a study data source. Twenty-two (3%) were Canadian-authored. There were significantly different publication levels in three categories between Canadian- and non-Canadian-authored publications. Based on publications per researchers, the Netherlands ranked first, while Canada ranked eighth of nine countries with 10 or more publications.

Conclusions: A relatively small body of literature focused on EMRs in primary health care exists; publications by Canadian authors were low. This study highlights the need to develop a strong evidence base to support the effective implementation and use of EMRs in Canadian primary health care.

Background: Adverse drug events may occur as a result of drug-drug interactions (DDIs). Information technology (IT) systems can be an important decision-making tool for healthcare workers to identify DDIs.

Objective: The aim of the study is to analyse drug prescriptions in our main hospital units, in order to measure the incidence and severity of potential DDIs. The utility of clinical decision-support systems (CDSSs) and computerised physician order entry (CPOE) in term of alerts adherence was also assessed. DDIs were assessed using a Micromedex® healthcare series database.

Methods: The system, adopted by the hospital, generates alerts for prescriptions with negative interactions and thanks to an 'acknowledgement function' it is possible to verify physician adherence to alerts. This function, although used previously, became mandatory from September 2010. Physician adherence to alerts and mean monthly incidence of potential DDIs in analysed units, before and after the mandatory 'acknowledgement function', were calculated.

Results: The intensive care unit (ICU) registered the greatest incidence of potential DDIs (49.0%), followed by the abdominal surgery unit and dialysis (43.4 and 42.0%, respectively). The cardiothoracic surgery unit (41.6%), step-down unit (38.3%) and post-anaesthesia care unit (30.0%) were comparable. The operating theatre and endoscopy registered the fewest potential DDIs (28.2 and 22.7%, respectively). Adherence to alerts after the 'acknowledgement function' increased by 25.0% in the ICU, 54.0% in the cardiothoracic surgery unit, 52.5% in the abdominal surgery unit, 58.0% in the stepdown unit, 67.0% in dialysis, 51.0% in endoscopy and 48.0% in the post-anaesthesia care unit. In the operating theatre, adherence to alerts decreased from 34.0 to 30.0%. The incidence of potential DDIs after mandatory use of the 'acknowledgement function' decreased slightly in endoscopy (-2.9%), the abdominal surgery unit (-2.7%), dialysis (-1.9%) and the step-down unit (-1.4%).

Conclusions: Improving DDI alerts will improved patient safety by more appropriately alerting clinicians.

Background: With the adoption of electronic medical records by medical group practices, there are opportunities to improve the quality of care for patients discharged from hospitals. However, there is little guidance for medical groups outside integrated hospital systems to automate the flow of patient information during transitions in care.

Objective: To describe the technological resources, expertise and time needed to develop an automated system providing information to ambulatory physicians when their patients are discharged from hospitals to home.

Development: Within a medical group practice, we developed an automated alert system that provides notification of discharges, reminders of the need for follow-up visits, drugs added during inpatient stays, and recommendations for laboratory monitoring of high-risk drugs. We tracked components of the information system required and the time spent by team members. We used USA national averages of hourly wages to estimate personnel costs.

Application: Critical components of the information system are notifications of hospital discharges through an admission, discharge and transfer registration (ADT) interface, linkage to the group's scheduling system, access to information on pharmacy dispensing and lab tests, and an interface engine. Total personnel cost was $76,314. Nearly half (47%) was for 614 hours by physicians who developed content, provided overall project management, and reviewed alerts to ensure that only 'actionable' alerts would be sent.

Conclusion: Implementing a system to provide information about hospital discharges requires strong internal informatics expertise, cooperation between facilities and ambulatory providers, development of electronic linkages, and extensive commitment of physician time.

Background: The advent of more mobile, more reliable, and more affordable videoconferencing technology finally makes it realistic to offer remote foreign language interpretation in the office setting. Still, such technologies deserve proof of acceptability to clinicians and patients before there is widespread acceptance and routine use.

Objective: We sought to examine: (1) the audio and video technical fidelity of iPad/Facetime(TM) software, (2) the acceptability of videoconferencing to patients and clinicians.

Methods: The convenience sample included Spanish-speaking adult patients at a community health care medicine clinic in 2011. Videoconferencing was conducted using two iPads(TM) connecting patient/physician located in the clinic examination room, and the interpreter in a remote/separate office in the same building. A five-item survey was used to solicit opinions on overall quality of the videoconferencing device, audio/video integrity/fidelity, perception of encounter duration, and attitude toward future use.

Results: Twenty-five patients, 18 clinicians and 5 interpreters participated in the project. Most patients (24/25) rated overall quality of videoconferencing as good/excellent with only 1 'fair' rating. Eleven patients rated the amount of time as no longer than in-person, and nine reported it as shorter than inperson. Most patients, 94.0% (24/25), favoured using videoconferencing during future visits. For the 18 clinicians, the results were similar.

Conclusions: Based on our experience at a singlesite community health centre, the videoconferencing technology appeared to be flawless, and both patients and clinicians were satisfied. Expansion of videoconferencing to other off-site healthcare professionals should be considered in the search for more cost-effective healthcare.

Background: Electronic medical records (EMRs) have the potential to improve the provision of preventive care by allowing general practitioners (GPs) to track and recall eligible patients and record testing for feedback on their service provision.

Objective: This study evaluates the effect of an educational intervention and feedback tool designed to teach GPs how to use their EMRs to improve their provision of preventive care.

Methods: A randomised controlled trial comparing rates of mammography, Papanicolaou tests, faecal occult blood tests and albumin creatinine ratios one-year pre- and post-intervention was conducted. Nine primary care practices (PCPs) representing over 30 000 patients were paired by practice size and experience of GPs, and randomly allocated to intervention or control groups. Physicians at the four intervention practices received a two-hour feedback session on their current level of preventive care and training to generate eligible patient lists for preventive services from their EMR database.

Results: One-year post-intervention results provided no evidence of a difference. The intervention was not a significant predictor of the one-year postintervention test rates for any of the four tests. On average, the intervention practices increased postintervention test rates on all tests by 16.8%, and control practices increased by 22.3%.

Conclusion: The non-significant results may be due to a variety of reasons, including the level of intensity of the educational intervention, the cointervention of a government programme which provided incentives to GPs meeting specific targets for preventive care testing or the level of recording of tests performed in the EMR.

Background: A computer-assisted history-taking system (CAHTS) is a tool that aids clinicians in gathering data from patients to inform a diagnosis or treatment plan. Despite the many possible applications and even though CAHTS have been available for nearly three decades, these remain underused in routine clinical practice.

Objective: Through an interpretative review of the literature, we provide an overview of the field of CAHTS, which also offers an understanding of the impact of these systems on policy, practice and research.

Methods: We conducted a search and critique of the literature on CAHTS. Using a comprehensive set of terms, we searched: MEDLINE, EMBASE, The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, The Cochrane Central Register of Controlled Trials, The Cochrane Methodology Register, Health Technology Assessment Database and the NHS Economic Evaluation Database over a ten-year period (January 1997 to May 2007) to identify systematic reviews, technical reports and health technology assessments, and randomised controlled trials.

Results: The systematic review of the literature suggests that CAHTS can save professionals' time, improve delivery of care to those with special needs and also facilitate the collection of information, especially potentially sensitive information (e.g. sexual history, alcohol consumption). The use of CAHTS also has disadvantages that impede the process of history taking and may pose risks to patients. CAHTS are inherently limited when detecting non-verbal communication, may pose irrelevant questions and frustrate the users with technical problems. Our review suggests that barriers such as a preference for pen-and-paper methods and concerns about data loss and security still exist and affect the adoption of CAHTS. In terms of policy and practice, CAHTS make input of data from disparate sites possible, which facilitates work from disparate sites and the collection of data for nationwide screening programmes such as the vascular risk assessment programme for people aged 40-74, now starting in England.

Conclusions: Our review shows that for CAHTS to be adopted in mainstream health care, important changes should take place in how we conceive, plan and conduct primary and secondary research on the topic so that we provide the framework for a comprehensive evaluation that will lead to an evidence base to inform policy and practice.

Background: The incorrect use of medications may result from improper prescribing. The poor interface and design of computerised physician order entry (CPOE) systems may contribute. To improve the quality of electronic drug prescription, ePrescribing, there is a need for an evaluation model that is able to assess the quality of the CPOE, focusing on usability.

Objective: To develop and apply a model to evaluate the usability of different CPOEs used for ePrescribing in electronic health records (EHRs) in primary care.

Method: An evaluation model for CPOEs was designed by assembling existing quality criteria for ePrescribing, supplemented with new criteria. The evaluation model was used to assess CPOEs from seven EHRs in primary care.

Results: The evaluation model included five categories comprising 73 single criteria. The model was found to be easy to use, and facilitated the assessment process. Evaluation of the EHRs revealed differences and similarities between the systems. None of the CPOEs was perfect in that all of them had distinct shortcomings. The most prominent deficiencies were a non-intuitive interface and incorrect dosage function.

Conclusion: The model developed might be used not only to evaluate usability in ePrescribing, but also as a basis for studying the usability of other CPOEs. To reduce the risk of drugs being prescribed with incorrect dosages, the most urgent improvement is the development of a more consistent and intuitive interface for the EHRs and an improvement in the dosage function.
