Detection and management of pornography-seeking in an online clinical dermatology atlas.

BACKGROUND: Increased use of an online educational archive of photographic dermatology case materials (DermAtlas) indicated unexpected pornography-seeking behavior and misuse. OBJECTIVE: We sought to assess the extent of archive misuse. METHODS: Web usage/request patterns were examined over a 6-month period for requests by anatomic site, diagnosis, and age group plus anatomic site. Free-text queries and referrals from external Web sites were reviewed. RESULTS: Of 7800 images, 5.5% contain genital sites. Of all requests, 11% were for anatomic sites (37% genital sites); 62% were specified for diagnoses (12% genital sites). When age group and anatomic site were specified, the relative risk of a child being requested (vs adult) was 1.48 (95% confidence interval 1.44-1.53). Of 10000 free text queries, 12% retrieved images containing genital sites. Of all referrals, 14.3% originated from nonmedical (pornography/fetish) Web sites. LIMITATIONS: Requests are mixed with legitimate queries. CONCLUSION: Online photographic dermatology archives are vulnerable to misuse. Monitoring and intervention are necessary to preserve their availability and integrity.

Error reduction in pediatric chemotherapy: computerized order entry and failure modes and effects analysis.

OBJECTIVE: To implement and evaluate the impact of computerized provider order entry (CPOE) on reducing ordering errors in pediatric chemotherapy. DESIGN: Before-and-after study from 2001 to 2004. SETTING: Pediatric Oncology in an academic medical center. INTERVENTION: Implementation of a CPOE system guided by multidisciplinary failure modes and effects analysis into pediatric chemotherapy. MAIN OUTCOME MEASURES: Completion data on chemotherapy steps of high morbidity/mortality potential if missed (as determined by attending oncologists) from 1259 pre-CPOE paper and 1116 post-CPOE pediatric chemotherapy orders. RESULTS: After CPOE deployment, daily chemotherapy orders were less likely to have improper dosing (relative risk [RR], 0.26; 95% confidence interval [CI], 0.11-0.61), incorrect dosing calculations (RR, 0.09; 95% CI, 0.03-0.34), missing cumulative dose calculations (RR, 0.32; 95% CI, 0.14-0.77), and incomplete nursing checklists (RR, 0.51; 95% CI, 0.33-0.80). There was no difference in the likelihood of improper dosing on treatment plans and a higher likelihood of not matching medication orders to treatment plans (RR, 5.4; 95% CI, 3.1-9.5). CONCLUSION: Failure modes and effects analysis-guided CPOE reduced ordering errors in pediatric chemotherapy and provided data for further improvements.

Computerized provider order entry and patient safety.

Computerized provider order entry (CPOE) and clinical decision support (CDS) are advocated health care information technologies for improving patient safety through reduction and prevention of medication errors. CPOE and DCS target specific errors in medication processes, particularly in prescribing and ordering. These are of particular importance in pediatrics, because children may be more vulnerable to prescribing errors than adults. Studies of CPOE/CDS performed at academic medical centers have demonstrated their effectiveness in reducing medication process errors in pediatrics, but scant data so far show effects on health outcomes. CPOE/CDS adoption requires significant expertise in health care processes, information technology, and change management. Adoption is a high-cost, high-risk venture with political implications.

Decreasing errors in pediatric continuous intravenous infusions.

OBJECTIVE: To evaluate the effect of a Web-based calculator and decision-support system on infusion ordering errors and to estimate error frequency in pharmacy infusion preparation. DESIGN: Data on ordering error frequency and typology were collected before and after implementation of an online infusion ordering system. Data on pharmacy preparation errors of infusions were collected. SETTING: A children's hospital at an academic medical center. PATIENTS: None. Data were abstracted from infusion orders. INTERVENTIONS: Introduction of a voluntary-use Web-based calculator into infusion ordering workflow. Observation only. MAIN OUTCOME MEASURES: Number and type of errors in handwritten and calculator-generated orders. Number and type of errors in pharmacy infusion preparation. RESULTS: Before calculator deployment, 129 sequential handwritten infusion orders were collected over 5 weeks. After deployment, of 162 sequential infusion orders, 88% (142) were calculator-generated. Calculator-generated infusion orders contained 83% fewer (p < .001) orders containing one or more errors than handwritten orders. Calculator-generated orders contained no high-risk errors (incorrect decimal, dose, or unit of measure) when compared with handwritten orders and were associated with fewer pharmacy interventions. In 118 sequential pharmacy infusion preparations over 4 wks, there were no errors observed. CONCLUSION: A Web-based calculator reduced significantly the total number of errors and eliminated all high-risk errors in the prescribing process for continuous pediatric infusions. With no observed errors in pharmacy preparation, this study provides data to support the use of computerized ordering as an independent safe and viable method for ordering continuous pediatric infusions.

Information resource preferences by general pediatricians in office settings: a qualitative study.

BACKGROUND: Information needs and resource preferences of office-based general pediatricians have not been well characterized. METHODS: Data collected from a sample of twenty office-based urban/suburban general pediatricians consisted of: (a) a demographic survey about participants' practice and computer use, (b) semi-structured interviews on their use of different types of information resources and (c) semi-structured interviews on perceptions of information needs and resource preferences in response to clinical vignettes representing cases in Genetics and Infectious Diseases. Content analysis of interviews provided participants' perceived use of resources and their perceived questions and preferred resources in response to vignettes. RESULTS: Participants' average time in practice was 15.4 years (2-28 years). All had in-office online access. Participants identified specialist/generalist colleagues, general/specialty pediatric texts, drug formularies, federal government/professional organization Websites and medical portals (when available) as preferred information sources. They did not identify decision-making texts, evidence-based reviews, journal abstracts, medical librarians or consumer health information for routine office use.In response to clinical vignettes in Genetics and Infectious Diseases, participants identified Question Types about patient-specific (diagnosis, history and findings) and general medical (diagnostic, therapeutic and referral guidelines) information. They identified specialists and specialty textbooks, history and physical examination, colleagues and general pediatric textbooks, and federal and professional organizational Websites as information sources. Participants with access to portals identified them as information resources in lieu of texts. For Genetics vignettes, participants identified questions about prenatal history, disease etiology and treatment guidelines. For Genetics vignettes, they identified patient history, specialists, general pediatric texts, Web search engines and colleagues as information sources. For Infectious Diseases (ID) vignettes, participants identified questions about patients' clinical status at presentation and questions about disease classification, diagnosis/therapy/referral guidelines and sources of patient education. For ID vignettes, they identified history, laboratory results, colleagues, specialists and personal experience as information sources. CONCLUSION: Content analysis of office-based general pediatricians' responses to clinical vignettes provided a qualitative description of their perceptions of information needs and preferences for information resource for cases in Genetics and Infectious Diseases. This approach may provide complementary information for discovering practitioner's information needs and resource preferences in different contexts.

Prevention of medication errors.

Medication error is the most frequent source of medical error that is associated with adverse events, and, in many cases, is preventable. Medication errors can occur at any step in the medication process. Medication error prevention and reduction begins with a systematic approach to their detection. An important approach to mitigating errors involves the reduction of variation in task performance using tested techniques and technologies from other industries. The most important component of error prevention and reduction is the proactive promotion of a safety culture by organizational leadership, with sustained education and support for users.

Blocking of pornography-seeking behavior in digital image libraries: adventures in the skin trade.

The escalating competition between online pornography - seeking and disseminating behaviors and technologies that attempt to reduce them creates technical, semantic and legal barriers to the legitimate discussion of and education about sensitive health issues involving sexuality, anatomy and pathology, especially when image-based knowledge is used. The effects of this competition on the use and management of an online dermatology atlas are described with a discussion on the importance of anticipating, addressing and controlling this problem while developing and maintaining image-based digital libraries and other e-Health applications.

The impact of the Internet on pediatric medicine.

The Internet has affected pediatricians and the families they serve in many ways by empowering users to manage information, and to communicate faster and more effectively. The Internet allows practitioners to store, retrieve, and manipulate patient-specific and general medical information within increasingly sophisticated integrated systems, allowing 'just-in-time' information at the point of care. Related technologies allow asynchronous, real-time, and mobile communication with colleagues, patients, and health organizations. These same technologies have empowered patients to seek health information independently from online libraries, support groups, and second opinions not previously available, creating knowledgeable and value-conscious healthcare consumers, thus evolving the nature of the physician-patient relationship. Because of these technology advances and their present and future effects on practice and patients, it is increasingly important for the general pediatrician to be aware of the potentials, practicalities, and pitfalls of the Internet with regard to general pediatrics.
