Hackathons as a means of accelerating scientific discoveries and knowledge transfer.

Scientific research plays a key role in the advancement of human knowledge and pursuit of solutions to important societal challenges. Typically, research occurs within specific institutions where data are generated and subsequently analyzed. Although collaborative science bringing together multiple institutions is now common, in such collaborations the analytical processing of the data is often performed by individual researchers within the team, with only limited internal oversight and critical analysis of the workflow prior to publication. Here, we show how hackathons can be a means of enhancing collaborative science by enabling peer review before results of analyses are published by cross-validating the design of studies or underlying data sets and by driving reproducibility of scientific analyses. Traditionally, in data analysis processes, data generators and bioinformaticians are divided and do not collaborate on analyzing the data. Hackathons are a good strategy to build bridges over the traditional divide and are potentially a great agile extension to the more structured collaborations between multiple investigators and institutions.

Paediatric acute lymphoblastic leukaemia and caesarean section: A report from the United Kingdom Childhood Cancer Study (UKCCS).

BACKGROUND: Reports have suggested that children born by caesarean initiated before labour onset may be at increased risk of developing acute lymphoblastic leukaemia (ALL). However, with most data being derived from case-control study interviews, information on the underpinning reasons for caesarean section is sparse, and evidence is conflicting. OBJECTIVES: Use clinical records compiled at the time of delivery to investigate the association between childhood ALL and caesarean delivery; examining timing in relation to labour onset, and reasons for the procedure. METHODS: Data are from the UK Childhood Cancer Study, a population-based case-control study conducted in the 1990s, when caesarean section rates were relatively low, in England, Scotland, and Wales. Children with ALL were individually matched to two controls on sex, date of birth, and region of residence. Information on mode of delivery and complications was abstracted from obstetric records. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression models adjusted for matching variables and relevant covariates. RESULTS: Around 75% of the 1034 cases and 1914 controls were born through unassisted vaginal delivery. Caesarean delivery was as frequent in cases and controls (OR 1.07, 95% CI 0.84, 1.36). No association was observed between ALL and caesarean delivery either during or before labour, with adjusted ORs of 1.08 (95% CI 0.78, 1.48) and 1.09 (95% CI 0.78, 1.53), respectively. For B-cell ALL, the ORs were 1.14 (95% CI 0.81, 1.59) for caesarean during labour and 1.21 (95% CI 0.85, 1.72) for prelabour. The underpinning reasons for caesarean delivery differed between cases and controls; with preeclampsia, although very rare, being more common amongst cases born by caesarean (OR 8.91, 95% CI 1.48, 53.42). CONCLUSIONS: Our obstetric record-based study found no significant evidence that caesarean delivery increased the risk of childhood ALL, either overall or when carried out before labour.

Roles of the underlying cause of delivery and gestational age on long-term child health.

BACKGROUND: Clinical conditions leading to delivery are heterogeneous. However, most studies examining the short- and long-term consequences of birth on child health only consider gestational age at delivery, not the underlying cause. OBJECTIVE: To examine the effect of both gestational age at delivery and underlying cause of delivery on child health outcomes. METHODS: This population-based retrospective cohort study of singleton infants born in Alberta (April 2004-March 2005) used linked administrative and perinatal data to identify birth subtypes by underlying cause (infection/inflammation (I/I), placental dysfunction (PD), both, or neither), gestational age at delivery, and child health outcomes (neonatal morbidity and mortality, paediatric complex chronic conditions, and neurodevelopmental disorders and disabilities). Poisson regression with robust variance was used to assess differences in the (adjusted) risk ratio (RR) of each outcome by gestational age, and by cause of delivery. The roles of gestational age and cause of delivery were examined using mediation analysis methods. RESULTS: A total of 38,192 children were included, with 66.7% experiencing neither I/I nor PD (I/I: 4.0%, PD: 27.5%, both: 1.8%). Infants born preterm had higher risk of all outcomes compared to those born at term and late-term. Infants with exposure to both causes had higher risk of all outcomes (neonatal morbidity, RR 8.96, 95% confidence interval [CI] 7.55, 10.63; paediatric complex chronic conditions, RR 3.94, 95% CI 3.08, 5.05; and neurodevelopmental disorders, RR 1.58, 95% CI 1.37, 1.84). The effect of underlying cause of delivery on child health outcomes was partially explained by gestational age, more in cases involving I/I than in those involving PD alone. CONCLUSIONS: Short- and long-term child health outcomes differ by the underlying cause leading to delivery, as well as the gestational age at delivery. Having a clearer prognosis for infants may promote the use of clinical interventions earlier for children at increased risk.

Exposure to Asian dust within a few days of delivery is associated with placental abruption in Japan: a case-crossover study.

OBJECTIVE: Asian dust is a natural phenomenon in which dust particles are transported from desert areas in China and Mongolia to East Asia. Short-term exposure to Asian dust has been associated with cardiovascular disease through mechanisms such as systemic inflammation. Because inflammation is a potential trigger of placental abruption, exposure may also lead to abruption. We examined whether exposure to Asian dust was associated with abruption. DESIGN: A bi-directional, time-stratified case-crossover design. SETTING AND POPULATION: From the Japan Perinatal Registry Network database, we identified 3014 patients who delivered singleton births in hospitals in nine Japanese prefectures from 2009 to 2014 with a diagnosis of placental abruption. METHODS: Asian dust levels were measured at Light Detection and Ranging monitoring stations, and these measurements were used to define the Asian dust days. As there was no information on the onset day of abruption, we assumed this day was the day before delivery (lag1). MAIN OUTCOME MEASURES: Placental abruption. RESULTS: During the study period, the Asian dust days ranged from 15 to 71 days, depending on the prefecture. The adjusted odds ratio of placental abruption associated with exposure to Asian dust was 1.4 (95% confidence interval = 1.0, 2.0) for cumulative lags of 1-2 days. Even after adjustment for co-pollutant exposures, this association did not change substantially. CONCLUSIONS: In this Japanese multi-area study, exposure to Asian dust was associated with an increased risk of placental abruption. TWEETABLE ABSTRACT: Exposure to environmental factors such as Asian dust may be a trigger of placental abruption.

Assessing Community Health Information Systems: Evidence from Child Health Records in Food Insecure Areas of the Ethiopian Highlands.

OBJECTIVES: This study assessed the completeness of child health records maintained and collected within community health information system in Ethiopia. METHODS: A household listing was carried out in 221 enumeration areas in food insecure areas of Ethiopia to determine the presence of a child less than 24-months. This list of children was then compared against the information stored at the local health posts. A household survey was administered to a sample of 2155 households that had a child less than 24-months of age to assess determinants and consequences of exclusion from the health post registers. RESULTS: Out of the 10,318 children identified during the listing, 36% were found from the health post records. Further analysis based on the household survey data indicated that health posts that had adopted nationally recommended recordkeeping practices had more complete records (p < 0.01) and that children residing farther from health posts were less likely to be found from the registers (p < 0.05). Mothers whose child was found from the registers were more likely to know a health extension worker (p < 0.01), had a contact with one (p < 0.01), and their child was more likely to have received growth monitoring (p < 0.05). CONCLUSIONS FOR PRACTICE: The incompleteness of the data collected at the health posts poses a challenge for effective implementation of the national health extension program and various complementary programs in Ethiopia.

Single screening versus conventional double screening for study selection in systematic reviews: a methodological systematic review.

BACKGROUND: Stringent requirements exist regarding the transparency of the study selection process and the reliability of results. A 2-step selection process is generally recommended; this is conducted by 2 reviewers independently of each other (conventional double-screening). However, the approach is resource intensive, which can be a problem, as systematic reviews generally need to be completed within a defined period with a limited budget. The aim of the following methodological systematic review was to analyse the evidence available on whether single screening is equivalent to double screening in the screening process conducted in systematic reviews. METHODS: We searched Medline, PubMed and the Cochrane Methodology Register (last search 10/2018). We also used supplementary search techniques and sources ("similar articles" function in PubMed, conference abstracts and reference lists). We included all evaluations comparing single with double screening. Data were summarized in a structured, narrative way. RESULTS: The 4 evaluations included investigated a total of 23 single screenings (12 sets for screening involving 9 reviewers). The median proportion of missed studies was 5% (range 0 to 58%). The median proportion of missed studies was 3% for the 6 experienced reviewers (range: 0 to 21%) and 13% for the 3 reviewers with less experience (range: 0 to 58%). The impact of missing studies on the findings of meta-analyses had been reported in 2 evaluations for 7 single screenings including a total of 18,148 references. In 3 of these 7 single screenings - all conducted by the same reviewer (with less experience) - the findings would have changed substantially. The remaining 4 of these 7 screenings were conducted by experienced reviewers and the missing studies had no impact or a negligible on the findings of the meta-analyses. CONCLUSIONS: Single screening of the titles and abstracts of studies retrieved in bibliographic searches is not equivalent to double screening, as substantially more studies are missed. However, in our opinion such an approach could still represent an appropriate methodological shortcut in rapid reviews, as long as it is conducted by an experienced reviewer. Further research on single screening is required, for instance, regarding factors influencing the number of studies missed.

The importance of including aliases in data linkage with vulnerable populations.

BACKGROUND: Records pertaining to individuals whose identity cannot be verified with legal documentation may contain errors, or be incorrect by intention of the individual. Probabilistic data linkage, especially in vulnerable populations where the incidence of such records may be higher, must be considerate of the usage of these records. METHODS: A data linkage was conducted between Queensland Youth Justice records and the Australian National Death Index. Links were assessed to determine how often they were made using the unverified (alias) records that would not have been made in their absence (i.e. links that were not also made using solely verified records). Anomalies in the linked records were investigated in order to make evaluations of the sensitivity and specificity of the linkage, compared to the links made using only verified records. RESULTS: From links made using verified records only, 1309 deaths were identified (2.6% of individuals). Using alias records in addition, the number of links increased by 16%. Links made using alias records only were more common in females, and those born after 1985. Different records belonging to the same individual in the justice dataset did not link to different death records, however there were instances of the same death record linking to multiple cohort individuals. CONCLUSIONS: The inclusion of aliases in data linkage in youths involved in the justice system increased mortality ascertainment without any discernible increase in false positive matches. We therefore conclude that alias records should be included in data linkage procedures in order to avoid biased attenuation of ascertainment in vulnerable populations, leading to the concealment of health inequality.

National Characteristics of Emergency Medical Services Responses for Older Adults in the United States.

OBJECTIVE: Older adults, those aged 65 and older, frequently require emergency care. However, only limited national data describe the Emergency Medical Services (EMS) care provided to older adults. We sought to determine the characteristics of EMS care provided to older adults in the United States. METHODS: We used data from the 2014 National Emergency Medical Services Information System (NEMSIS), encompassing EMS response data from 46 States and territories. We excluded EMS responses for children <18 years, interfacility transports, intercepts, non-emergency medical transports, and standby responses. We defined older adults as age ≥65 years. We compared patient demographics (age, sex, race, primary payer), response characteristics (dispatch time, location type, time intervals), and clinical course (clinical impression, injury, procedures, medications) between older and younger adult EMS emergency 9-1-1 responses. RESULTS: During the study period there were 20,212,245 EMS emergency responses. Among the 16,116,219 adult EMS responses, there were 6,569,064 (40.76%) older and 9,547,155 (59.24%) younger adults. Older EMS patients were more likely to be white and the EMS incident to be located in healthcare facilities (clinic, hospital, nursing home). Compared with younger patients, older EMS patients were more likely to present with syncope (5.68% vs. 3.40%; OR 1.71; CI: 1.71-1.72), cardiac arrest/rhythm disturbance (3.27% vs. 1.69%; OR 1.97; CI: 1.96-1.98), stroke (2.18% vs. 0.74%; OR 2.99; CI: 2.96-3.02) and shock (0.77% vs. 0.38%; OR 2.02; CI: 2.00-2.04). Common EMS interventions performed on older persons included intravenous access (32.02%), 12-lead ECG (14.37%), CPR (0.87%), and intubation (2.00%). The most common EMS drugs administered to older persons included epinephrine, atropine, furosemide, amiodarone, and albuterol or ipratropium. CONCLUSION: One of every three U.S. EMS emergency responses involves older adults. EMS personnel must be prepared to care for the older patient.

[Applying the Diffusion of Innovation Theory to Improve the Prevalence of Use of a Disease Management Information System].

BACKGROUND & PROBLEMS: The unit promoted the use of a disease management information system, but lacked consensus regarding its use. The problems that were identified included: the business-oriented design of the information system, lack of education and training, dual-track operations, and awkward operation interface. Use of the information system among nurses in the unit had thus decreased over time. PURPOSE: To increase the prevalence of use of the disease management information system. RESOLUTIONS: The diffusion of innovation theory was applied to strengthen the innovative characteristics of the disease management information system. The improvement measures adopted included: incorporation of recommendations, revision of the information system, provision of testing, arranging education and training sessions for the nurses, implementation of a regular audit system, and the revision of standard operating procedures. RESULTS: The prevalence of use of the disease management information system increased from 33.3% pretest to 100% posttest. CONCLUSIONS: This project applied the diffusion of innovation theory to strengthen the innovative characteristics of the disease management information system, guide the nurses to adapt and change, and improve their use of and satisfaction with the disease management information system.

Evaluating Nurses' Satisfaction With Two Nursing Information Systems.

Evaluating user satisfaction is one of the methods to ensure the usability of information systems. Considering the importance of nursing information systems in patient health, the objective of this study is to evaluate nurses' satisfaction with two widely used nursing information systems (Peyvand Dadeh and Tirazhe) in Iran. This descriptive-analytical study was done on 230 nurses in all teaching hospitals of Kerman University of Medical Sciences in 2015. Data were collected using an augmented version of a questionnaire developed by IBM. Data were analyzed by SPSS.16 using descriptive and analytical statistical methods including t test, analysis of variance, and Pearson correlation coefficient. The mean of overall satisfaction with the two systems was 61 ± 2.2 and 74 ± 2.4, respectively. The mean of satisfaction with different systems dimensions, that is, ease of use, information quality, and interface quality, was, respectively, 24 ± 1.9, 26 ± 9.7, and 12 ± 4.7 for Tirazhe and 29 ± 1.1, 39 ± 1.04 and 13 ± 5.3 for Peyvand Dadeh system. Nurses' satisfaction with both systems was at a medium level. The majority of nurses were relatively satisfied with the information quality and user interface quality of these systems. The results suggest that designing nursing information systems in accordance with their users' need improves usability. Hence, policy and decision makers of healthcare institutions should invest on usability when purchasing such systems.

Investigation of the Effects of a Nursing Information System by Using the Technology Acceptance Model.

The purposes of this study are to investigate the effectiveness of implementing a nursing information system and to discuss several issues affecting its successful deployment from the perspectives of nurses, the major users of the system. The methodology was based on the theory of the technology acceptance model. This study adopted a cross-sectional study method to survey and collect data. In total, 167 questionnaires were distributed to subjects. Approximately 94.6%, or 158 valid questionnaires, were collected. The data were analyzed using SPSS and PLS software.The data analysis indicated that the factors that most significantly influenced the willingness of nurses to use the nursing information system were their degrees of satisfaction with the system and their perceptions of its usefulness. A nursing information system that can provide functions that are useful and convenient and that facilitate the avoidance of tedious repetitive writing and improve the quality of provided care can encourage nurse satisfaction with the system and thus stimulate their interest in using it for their work. The ease of use of the system can also affect the willingness of nurses to use it.

A Nursing Pain Assessment and Record Information System: Design and Application in the Oncology Department.

Pain is an unpleasant sensory and emotional feeling accompanying existing, impending, or potential tissue damage. Valid pain assessment and standardized pain documentation are important in oncology pain management; however, they are still deficient. Thus, we developed a pain assessment and record information system for nurses in the oncology department and implemented a questionnaire survey to evaluate users' acceptance of the system. The pain assessment system focused on usability and efficiency to provide a modified workflow that was safe, less time-consuming, patient centered, enjoyable, and efficient. The pain assessment and record chart types in the system enabled greater standardization of pain assessments and records. The application of the system greatly improved the efficiency of nursing in the oncology department, guiding nurses in an accurate and comprehensive patient pain assessment and contributing significantly to further improvement in pain care standards and care decisions. Nurses and doctors surveyed reported a high degree of satisfaction with factors such as saving time and improving the capacity of pain control, suggesting that the system enhanced the quality of pain management. Through this system, we can promote pain management, improving care quality for patients.

Online information search behaviour of physicians.

BACKGROUND: Although doctors increasingly engage in online information seeking to complement their medical practice, little is known regarding what online information sources are used and how effective they are. OBJECTIVE: Grounded on self-determination and needs theory, this study posits that doctors tend to use online information sources to fulfil their information requirements in three pre-defined areas: patient care, knowledge development and research activities. Fulfilling these information needs is argued to improve doctors' perceived medical practice competence. METHODS: Performing PLS-SEM analysis on primary survey data from 303 medical doctors practicing in four major Greek hospitals, a conceptual model is empirically tested. RESULTS: Using authoritative online information sources was found to fulfil all types of information needs. Contrarily, using non-authoritative information sources had no significant effect. Satisfying information requirements relating to patient care and research activities enhanced doctors' perceptions about their medical practice competence. In contrast, meeting knowledge development information needs had the opposite result. DISCUSSION: Consistent with past studies, outcomes indicate that doctors tend to use non-authoritative online information sources; yet their use was found to have no significant value in fulfilling their information requirements. CONCLUSIONS: Authoritative online information sources are found to improve perceived medical practice competence by satisfying doctors' diverse information requirements.

A Systematic Review of Techniques and Sources of Big Data in the Healthcare Sector.

The main objective of this paper is to present a review of existing researches in the literature, referring to Big Data sources and techniques in health sector and to identify which of these techniques are the most used in the prediction of chronic diseases. Academic databases and systems such as IEEE Xplore, Scopus, PubMed and Science Direct were searched, considering the date of publication from 2006 until the present time. Several search criteria were established as 'techniques' OR 'sources' AND 'Big Data' AND 'medicine' OR 'health', 'techniques' AND 'Big Data' AND 'chronic diseases', etc. Selecting the paper considered of interest regarding the description of the techniques and sources of Big Data in healthcare. It found a total of 110 articles on techniques and sources of Big Data on health from which only 32 have been identified as relevant work. Many of the articles show the platforms of Big Data, sources, databases used and identify the techniques most used in the prediction of chronic diseases. From the review of the analyzed research articles, it can be noticed that the sources and techniques of Big Data used in the health sector represent a relevant factor in terms of effectiveness, since it allows the application of predictive analysis techniques in tasks such as: identification of patients at risk of reentry or prevention of hospital or chronic diseases infections, obtaining predictive models of quality.

Innovative Power of Health Care Organisations Affects IT Adoption: A bi-National Health IT Benchmark Comparing Austria and Germany.

Multinational health IT benchmarks foster cross-country learning and have been employed at various levels, e.g. OECD and Nordic countries. A bi-national benchmark study conducted in 2007 revealed a significantly higher adoption of health IT in Austria compared to Germany, two countries with comparable healthcare systems. We now investigated whether these differences still persisted. We further studied whether these differences were associated with hospital intrinsic factors, i.e. the innovative power of the organisation and hospital demographics. We thus performed a survey to measure the "perceived IT availability" and the "innovative power of the hospital" of 464 German and 70 Austrian hospitals. The survey was based on a questionnaire with 52 items and was given to the directors of nursing in 2013/2014. Our findings confirmed a significantly greater IT availability in Austria than in Germany. This was visible in the aggregated IT adoption composite score "IT function" as well as in the IT adoption for the individual functions "nursing documentation" (OR = 5.98), "intensive care unit (ICU) documentation" (OR = 2.49), "medication administration documentation" (OR = 2.48), "electronic archive" (OR = 2.27) and "medication" (OR = 2.16). "Innovative power" was the strongest factor to explain the variance of the composite score "IT function". It was effective in hospitals of both countries but significantly more effective in Austria than in Germany. "Hospital size" and "hospital system affiliation" were also significantly associated with the composite score "IT function", but they did not differ between the countries. These findings can be partly associated with the national characteristics. Indicators point to a more favourable financial situation in Austrian hospitals; we thus argue that Austrian hospitals may possess a larger degree of financial freedom to be innovative and to act accordingly. This study is the first to empirically demonstrate the effect of "innovative power" in hospitals on health IT adoption in a bi-national health IT benchmark. We recommend directly including the financial situation into future regression models. On a political level, measures to stimulate the "innovative power" of hospitals should be considered to increase the digitalisation of healthcare.

The Contribution of Sociotechnical Factors to Health Information Technology-Related Sentinel Events.

BACKGROUND: An understanding of how health information technology (health IT) can contribute to sentinel events is necessary to learn how to safely implement and use health IT. An analysis was conducted to explore how health IT may contribute to adverse events that result in death or severe harm to the patient. METHODS: For 3,375 de-identified sentinel events voluntarily reported to The Joint Commission between January 1, 2010, and June 30, 2013, categorical and keyword queries were used to search for potential health IT-related events. Each of the identified events was reviewed on the basis of findings from root cause analyses (RCAs) to determine if health IT contributed to or caused the event, and if so, how and why. The contributing factors were classified using a composite of existing classification schemes. RESULTS: A total of 120 health IT-related sentinel events (affecting 125 patients) were identified. More than half resulted in patient death, 30% resulted in unexpected or additional care, and 11% resulted in permanent loss of function. The three most frequently identified event types were (1) medication errors, (2) wrong-site surgery (including the wrong side, wrong procedure, and wrong patient), and (3) delays in treatment. Contributing factors were most frequently associated with the human-computer interface, workflow and communication, and clinical content-related issues. CONCLUSIONS: The classification of health IT-related contributing factors indicates that health IT-related events are primarily associated with the sociotechnical dimensions of human-computer interface, workflow and communication, and clinical content. Improved identification of health IT-related contributing factors in the context of the sociotechnical dimensions may help software developers, device manufacturers, and end users in health care organizations proactively identify vulnerabilities and hazards, ultimately reducing the risk of harm to patients.

A Patient-Centered Framework for Evaluating Digital Maturity of Health Services: A Systematic Review.

BACKGROUND: Digital maturity is the extent to which digital technologies are used as enablers to deliver a high-quality health service. Extensive literature exists about how to assess the components of digital maturity, but it has not been used to design a comprehensive framework for evaluation. Consequently, the measurement systems that do exist are limited to evaluating digital programs within one service or care setting, meaning that digital maturity evaluation is not accounting for the needs of patients across their care pathways. OBJECTIVE: The objective of our study was to identify the best methods and metrics for evaluating digital maturity and to create a novel, evidence-based tool for evaluating digital maturity across patient care pathways. METHODS: We systematically reviewed the literature to find the best methods and metrics for evaluating digital maturity. We searched the PubMed database for all papers relevant to digital maturity evaluation. Papers were selected if they provided insight into how to appraise digital systems within the health service and if they indicated the factors that constitute or facilitate digital maturity. Papers were analyzed to identify methodology for evaluating digital maturity and indicators of digitally mature systems. We then used the resulting information about methodology to design an evaluation framework. Following that, the indicators of digital maturity were extracted and grouped into increasing levels of maturity and operationalized as metrics within the evaluation framework. RESULTS: We identified 28 papers as relevant to evaluating digital maturity, from which we derived 5 themes. The first theme concerned general evaluation methodology for constructing the framework (7 papers). The following 4 themes were the increasing levels of digital maturity: resources and ability (6 papers), usage (7 papers), interoperability (3 papers), and impact (5 papers). The framework includes metrics for each of these levels at each stage of the typical patient care pathway. CONCLUSIONS: The framework uses a patient-centric model that departs from traditional service-specific measurements and allows for novel insights into how digital programs benefit patients across the health system. TRIAL REGISTRATION: N/A.

Information Needs of Men with Localized Prostate Cancer During Radiation Therapy.

The purpose of this study was to describe how patient information needs change over the course of receiving radiation therapy for prostate cancer. Convenience sampling was utilized to recruit men with stage I-III prostate cancer. A longitudinal repeated measures design was implemented for this pilot study. Patients were presented with 36 paired comparisons, each asking the participant to choose the most important information topic(s) for today. Following completion of the survey instruments, the clinic nurse delivered the four top-ranked information topic handouts to each patient with brief instruction on how to use the handouts. Over the course of 6 months, we were able to recruit 35 men. The four highest priority topics across all four sessions were prognosis, stage of disease, treatment options, and side effects. Our results suggest trends in the information priorities that men hold over the course of radiation treatment. The information priorities do appear to shift over time, notably prognosis concerns and risk for family members continued to rise over time, while side effect information declined. These findings will extend an already strong foundation of evidence for preparatory information in radiation therapy. Furthermore, these findings will strengthen current evidence that computerized assessment of patient self-report information is feasible and an important adjunct to clinical practice.

Nursing Information Systems Requirements: A Milestone for Patient Outcome and Patient Safety Improvement.

Considering the integral role of understanding users' requirements in information system success, this research aimed to determine functional requirements of nursing information systems through a national survey. Delphi technique method was applied to conduct this study through three phases: focus group method modified Delphi technique and classic Delphi technique. A cross-sectional study was conducted to evaluate the proposed requirements within 15 general hospitals in Iran. Forty-three of 76 approved requirements were clinical, and 33 were administrative ones. Nurses' mean agreements for clinical requirements were higher than those of administrative requirements; minimum and maximum means of clinical requirements were 3.3 and 3.88, respectively. Minimum and maximum means of administrative requirements were 3.1 and 3.47, respectively. Research findings indicated that those information system requirements that support nurses in doing tasks including direct care, medicine prescription, patient treatment management, and patient safety have been the target of special attention. As nurses' requirements deal directly with patient outcome and patient safety, nursing information systems requirements should not only address automation but also nurses' tasks and work processes based on work analysis.

Factors Associated With Provider Reporting of Child and Adolescent Vaccination History to Immunization Information Systems: Results From the National Immunization Survey, 2006-2012.

CONTEXT: Use of Immunization information systems (IISs) by providers can improve vaccination rates by identifying missed opportunities. However, provider reporting of children's vaccination histories to IISs remains suboptimal. OBJECTIVE: To assess factors associated with provider reporting to an IIS. DESIGN: Analysis of 2006-2012 National Immunization Survey (NIS) and NIS-Teen data. NIS and NIS-Teen are ongoing random-digit-dial telephone surveys of households with children and adolescents, respectively, followed by a mail survey to providers to obtain the patient's vaccination history. SETTING AND PARTICIPANTS: A total of 115 285 children aged 19 to 35 months and 83 612 adolescents aged 13 to 17 years and their immunization providers in the United States. MAIN OUTCOME MEASURES: The percentage of children and adolescents with 1 or more providers reporting to or obtaining vaccination information from their local IISs. Multivariable logistic regression was used to examine patient and provider factors associated with provider reporting to IISs and adjusted prevalence of children and adolescents with 1 or more providers reporting to IISs. RESULTS: In 2012, 79.4% of children and 77.4% of adolescents had 1 or more providers report any of their vaccination data to an IIS, and 41.9% of children and 51.5% of adolescents had providers who obtained any of their vaccination histories from an IIS. During 2006-2012, children and adolescents were more likely to have any of their vaccination data reported to an IIS if they received care from all public versus all private providers (children: 84.4% vs 69.6%, P < .0001; adolescents: 84.6% vs 66.4%, P < .0001), had 1 or more providers who ordered vaccines from a state or local health department (children: 76.7% vs 59.5%, P < .0001; adolescents: 77.0% vs 55.6%, P < .0001), or had 1 or more providers obtain vaccination information from the IIS (children: 86.1% vs 71.2%, P < .0001; adolescents: 83.7% vs 64.6%, P < .0001). CONCLUSIONS: Health department staff should target providers less likely to use IIS services, including private providers, and providers not ordering vaccines from health departments to ensure they use IIS services.
