Objective
To systematically review existing literature regarding patient engagement technologies used in the inpatient setting.Methods
PubMed, Association for Computing Machinery (ACM) Digital Library, Institute of Electrical and Electronics Engineers (IEEE) Xplore, and Cochrane databases were searched for studies that discussed patient engagement (‘self-efficacy’, ‘patient empowerment’, ‘patient activation’, or ‘patient engagement’), (2) involved health information technology (‘technology’, ‘games’, ‘electronic health record’, ‘electronic medical record’, or ‘personal health record’), and (3) took place in the inpatient setting (‘inpatient’ or ‘hospital’). Only English language studies were reviewed.Results
17 articles were identified describing the topic of inpatient patient engagement. A few articles identified design requirements for inpatient engagement technology. The remainder described interventions, which we grouped into five categories: entertainment, generic health information delivery, patient-specific information delivery, advanced communication tools, and personalized decision support.Conclusions
Examination of the current literature shows there are considerable gaps in knowledge regarding patient engagement in the hospital setting and inconsistent use of terminology regarding patient engagement overall. Research on inpatient engagement technologies has been limited, especially concerning the impact on health outcomes and cost-effectiveness. 相似文献2.

Objective
To compare the pattern of jaundice resolution among children with severe malaria treated with quinine and artemether.Methods
Thirty two children who fulfilled the inclusion criteria were recruited for the study from two hospitals with intensive care facilities. They were divided into two groups; ‘Q’ and ‘A’, receiving quinine and artemether, respectively. Jaundice was assessed by clinical examination.Results
Sixteen out of 32 children recruited (representing 50%) presented with jaundice on the day of recruitment. The mean age was (7.00°C2.56) years. On day 3, four patients in ‘A’ and six patients in ‘Q’ had jaundice. By day 7, no child had jaundice.Conclusion
The study has shown that both drugs resolve jaundice although artemether relatively resolves it faster by the third day. 相似文献3.
Background
Syndrome ‘X’, a clustering of impaired glucose tolerance (IGT), raised blood pressure, raised serum triglycerides and low HDL-cholesterol, occurring under the influence of insulin resistance and resultant hyperinsulinaemia, has been hypothesised to be a major risk factor for ischaemic heart disease (IHD). However, there is a lack of research based evidence in this field, in our country.Methods
The study was a cross-sectional analytical epidemiological design of 614 healthy Indian Army personnel, aged 35 years and above, selected by random sampling.Results
The study indicated that there is a statistically significant (p < 0.001) clustering between fasting hyperinsulinaemia, raised blood pressure, IGT, raised triglycerides and low HDL. The prevalence of syndrome ‘X’ was 8.47% (95% CI 6.27% to 10.47%). Initial univariate and subsequent multivariate analysis using multiple logistic regression method, indicated that predictors of syndrome ‘X’ were increasing age, overweight, increasing central (abdominal) obesity, lack of adequate physical exercise and low level of physical fitness. Presence of syndrome ‘X’ increased the risk of resting ECG changes suggestive of coronary insufficiency (OR = 6.29, p < 0.001).Conclusion
Based on the findings, recommendations for prevention of this syndrome have been submitted.Key Words: Syndrome ‘X’, Insulin resistance syndrome, Ischaemic heart disease, Coronary Risk factors, Military personnel 相似文献4.
Background
The difficulty with insecticide treated mosquito nets is that in military operation, it may not be practical for the personnel to carry mosquito nets with them. In mobile military operations, availability of pre-treated ‘patches of cloth’ or ‘bands’, which can be applied over the uniform at strategic sites, could be a feasible alternative.Methods
A double blind randomised controlled trial was undertaken among troops deployed in counter-insurgency operations in the northeastern parts of the country, to assess the efficacy of synthetic pyrethroid pretreated patches in reducing man mosquito contact, as compared to conventional repellents.Result
The study indicated that pretreated patches, when affixed over the uniform, provided significantly higher protection from mosquito bites, when used in addition to the conventional repellents.Conclusion
The study recommends that synthetic pyrethroid treated patches be made available to troops operating in highly malarious areas.Key Words: Synthetic pyrethroid treated patches, Man-mosquito contact 相似文献5.
Background
The successful conduct of fiberoptic aided intubation is dependent upon effective local anaesthesia. The aim of the study was to compare three different methods of anaesthetizing the airway.Methods
60 adult patients (American Society of Anaesthesiologists status I-III and Mallampati class III & IV), scheduled for elective surgery, received sedation followed by spraying of the nares and posterior pharyngeal wall with 4% lignocaine. Thereafter the patients received 4 ml of 4% lignocaine either by transtracheal injection (n=20, group A), via intubating fiberscope (Pentax F1-10P2) using ‘spray as you go’ technique (n=20, group B) or by nebulizer (Devilbiss 5610W) 20 min before intubation, (n=20, group C). Patients were asked to score the procedure using visual analog scale (VAS) and severity scores. Episodes of coughing, choking, stridor, extra / total local anaesthetic used and intubation times were recorded. Patients were monitored continuously for vital parameters.Results
Group B patients showed better VAS scores with shorter intubation times and had a lower incidence of coughing and choking. The endoscopists’ VAS scores also showed a preference for group B.Conclusion
In conclusion the ‘spray as you go’ technique was safe, provided effective local anaesthesia and was preferred by both patients and endoscopists.Key Words: Awake intubation, Difficult airway, Fiberoptic intubation 相似文献6.

Background
Craniotomy and excision of tumours can produce neurological deficits if the tumour is located close to eloquent areas of the brain. One technique of overcoming this problem is to keep the patient ‘awake’ during surgery.Methods
Eight patients with intra cranial space occupying lesions (ICSOL) were operated ‘awake’, using a combination of skull block with sedation and analgesia. A mixture of 0.125% bupivacaine and 0.5% lignocaine was used for various nerve and field blocks. Midazolam, fentanyl and propofol in titrated doses were used to achieve conscious sedation.Result
The procedure was successful in all the patients. They tolerated the procedure well and were able to follow the commands intraoperatively as desired. There were no significant complications.Conclusion
Awake craniotomy with skull blocks with sedation and analgesia is a well established procedure. It requires a good rapport between surgeon, anaesthesiologist and the patient.Key Words: Awake craniotomy, Skull block, Sedation, Analgesia 相似文献7.
Background
In patients with Polycystic Ovarian Syndrome (PCOS), resolution of infertility is an important goal of treatment. Wedge resection of the ovaries described as a means to achieve this was practiced in the middle of twentieth century. With the advent of endoscopic surgery, surgical approach for the same condition has been modified. Multi point biopsy, multiple needle puncture, electofulguration and laser fulguration are being tried in the context of PCOS. This project was taken up to evaluate the scope of electo fulguration in clomiphene resistant PCOS.Methods
Forty patients who did not show sonographic evidence of ovulation with clomiphene citrate (CC) 100mg OD for 05 days in two cycles were subjected to laparoscopy. The patients who did not show any pelvic factor for infertility were alternately assigned to electro - fulguration treatment of ovaries or no fulguration during laparoscopy. These were designated as ‘Lap EC’ & ‘Only CC’ group respectively. For ‘Only CC’ group’ stimulation with CC was continued for four cycles with a higher dose 150 mg OD for 05 days. Lap EC group were subjected to CC 100mg OD for 5 days for two cycles in case of non achievement of ovulation in the first two drug free cycles following EC. Folliculometry, HCG administration and Intra Uterine Insemination (IUI) was performed for both groups.Results
Total percentage of ovulatory cycles were 51.8% in EC group compared to 5.26% in the CC group. Overall pregnancy rate of 30% was achieved in the Lap EC group as compared to only 10% in the CC group (p<0.05).Conclusion
Laparoscopic electrofulguration of ovaries increases the chances of ovulation and conception. This being a cheaper one time procedure as compared to other expensive ovulation inducing agents, should be the preferred mode and the primary procedure wherever polycystic ovaries are encountered while evaluating a case of infertility by laparoscopy.Key Words: Infertility, PCOS, Electrofulguration 相似文献8.

Background
The electronic exchange of health information among healthcare providers has the potential to produce enormous clinical benefits and financial savings, although realizing that potential will be challenging. The American Recovery and Reinvestment Act of 2009 will reward providers for ‘meaningful use’ of electronic health records, including participation in clinical data exchange, but the best ways to do so remain uncertain.Methods
We analyzed patient visits in one community in which a high proportion of providers were using an electronic health record and participating in data exchange. Using claims data from one large private payer for individuals under age 65 years, we computed the number of visits to a provider which involved transitions in care from other providers as a percentage of total visits. We calculated this ‘transition percentage’ for individual providers and medical groups.Results
On average, excluding radiology and pathology, approximately 51% of visits involved care transitions between individual providers in the community and 36%–41% involved transitions between medical groups. There was substantial variation in transition percentage across medical specialties, within specialties and across medical groups. Specialists tended to have higher transition percentages and smaller ranges within specialty than primary care physicians, who ranged from 32% to 95% (including transitions involving radiology and pathology). The transition percentages of pediatric practices were similar to those of adult primary care, except that many transitions occurred among pediatric physicians within a single medical group.Conclusions
Care transition patterns differed substantially by type of practice and should be considered in designing incentives to foster providers'' meaningful use of health data exchange services. 相似文献10.
Background
This study was undertaken to study the motivational factors leading to voluntary blood donation and understanding the psychosocial variables of blood donors.Methods
300 blood donors were selected by systematic random sampling method.Result
It was observed that most of the voluntary donors were males (89.3%) and belonged to age group 16-25 years (48%). Most of the donors (93.46%) had studied upto high school and above and 84.33% of the donors belonged to the middle class. 27% of the donors had donated blood previously. The common motivational factors to donate blood were for ‘a good cause'', ‘for the society’ and ‘to save a life''. 4.67% of them donated blood for self satisfaction.Conclusion
Motivation, recruitment and retention of voluntary blood donors are important criteria to achieve safe blood donation.Key Words: Motivation, Psychosocial, Voluntary, Blood Donors 相似文献11.

Objectives
To test the feasibility of using text mining to depict meaningfully the experience of pain in patients with metastatic prostate cancer, to identify novel pain phenotypes, and to propose methods for longitudinal visualization of pain status.Materials and methods
Text from 4409 clinical encounters for 33 men enrolled in a 15-year longitudinal clinical/molecular autopsy study of metastatic prostate cancer (Project to ELIminate lethal CANcer) was subjected to natural language processing (NLP) using Unified Medical Language System-based terms. A four-tiered pain scale was developed, and logistic regression analysis identified factors that correlated with experience of severe pain during each month.Results
NLP identified 6387 pain and 13 827 drug mentions in the text. Graphical displays revealed the pain ‘landscape’ described in the textual records and confirmed dramatically increasing levels of pain in the last years of life in all but two patients, all of whom died from metastatic cancer. Severe pain was associated with receipt of opioids (OR=6.6, p<0.0001) and palliative radiation (OR=3.4, p=0.0002). Surprisingly, no severe or controlled pain was detected in two of 33 subjects’ clinical records. Additionally, the NLP algorithm proved generalizable in an evaluation using a separate data source (889 Informatics for Integrating Biology and the Bedside (i2b2) discharge summaries).Discussion
Patterns in the pain experience, undetectable without the use of NLP to mine the longitudinal clinical record, were consistent with clinical expectations, suggesting that meaningful NLP-based pain status monitoring is feasible. Findings in this initial cohort suggest that ‘outlier’ pain phenotypes useful for probing the molecular basis of cancer pain may exist.Limitations
The results are limited by a small cohort size and use of proprietary NLP software.Conclusions
We have established the feasibility of tracking longitudinal patterns of pain by text mining of free text clinical records. These methods may be useful for monitoring pain management and identifying novel cancer phenotypes. 相似文献12.
Objective
To evaluate the validity of, characterize the usage of, and propose potential research applications for International Classification of Diseases, Ninth Revision (ICD-9) tobacco codes in clinical populations.Materials and methods
Using data on cancer cases and cancer-free controls from Vanderbilt''s biorepository, BioVU, we evaluated the utility of ICD-9 tobacco use codes to identify ever-smokers in general and high smoking prevalence (lung cancer) clinic populations. We assessed potential biases in documentation, and performed temporal analysis relating transitions between smoking codes to smoking cessation attempts. We also examined the suitability of these codes for use in genetic association analyses.Results
ICD-9 tobacco use codes can identify smokers in a general clinic population (specificity of 1, sensitivity of 0.32), and there is little evidence of documentation bias. Frequency of code transitions between ‘current’ and ‘former’ tobacco use was significantly correlated with initial success at smoking cessation (p<0.0001). Finally, code-based smoking status assignment is a comparable covariate to text-based smoking status for genetic association studies.Discussion
Our results support the use of ICD-9 tobacco use codes for identifying smokers in a clinical population. Furthermore, with some limitations, these codes are suitable for adjustment of smoking status in genetic studies utilizing electronic health records.Conclusions
Researchers should not be deterred by the unavailability of full-text records to determine smoking status if they have ICD-9 code histories. 相似文献13.

Objective
Without careful attention to the work of users, implementation of health IT can produce new risks and inefficiencies in care. This paper uses the technology use mediation framework to examine the work of a group of nurses who serve as mediators of the adoption and use of a barcode medication administration (BCMA) system in an inpatient setting.Materials and methods
The study uses ethnographic methods to explore the mediators'' work. Data included field notes from observations, documents, and email communications. This variety of sources enabled triangulation of findings between activities observed, discussed in meetings, and reported in emails.Results
Mediation work integrated the BCMA tool with nursing practice, anticipating and solving implementation problems. Three themes of mediation work include: resolving challenges related to coordination, integrating the physical aspects of BCMA into everyday practice, and advocacy work.Discussion
Previous work suggests the following factors impact mediation effectiveness: proximity to the context of use, understanding of users'' practices and norms, credibility with users, and knowledge of the technology and users'' technical abilities. We describe three additional factors observed in this case: ‘influence on system developers,’ ‘influence on institutional authorities,’ and ‘understanding the network of organizational relationships that shape the users'' work.’Conclusion
Institutionally supported clinicians who facilitate adoption and use of health IT systems can improve the safety and effectiveness of implementation through the management of unintended consequences. Additional research on technology use mediation can advance the science of implementation by providing decision-makers with theoretically durable, empirically grounded evidence for designing implementations. 相似文献14.

Words and statements that depict how activities and attitudes of health professionals may expose TB patients to stigmatizationResults
Five interrelated ways by which activities and attitudes of health professionals may expose TB patients to stigmatization in the community were identified in data: TB control practices; fear-based responses to TB; inappropriate health education messages; medical licensing for sellers; and prohibition of burial rites.Conclusions
The findings may explain the diagnostic delay and low TB case detection rate in Ghana. This calls for intensification of education on TB and regular organization of refresher courses and possibly retraining of health professionals in TB control and management. When health professionals are seen to be treating TB patients as ‘normal’ individuals, it has the potential of changing the society''s perception about the disease. 相似文献15.

Objective
To describe a system for determining the assertion status of medical problems mentioned in clinical reports, which was entered in the 2010 i2b2/VA community evaluation ‘Challenges in natural language processing for clinical data’ for the task of classifying assertions associated with problem concepts extracted from patient records.Materials and methods
A combination of machine learning (conditional random field and maximum entropy) and rule-based (pattern matching) techniques was used to detect negation, speculation, and hypothetical and conditional information, as well as information associated with persons other than the patient.Results
The best submission obtained an overall micro-averaged F-score of 0.9343.Conclusions
Using semantic attributes of concepts and information about document structure as features for statistical classification of assertions is a good way to leverage rule-based and statistical techniques. In this task, the choice of features may be more important than the choice of classifier algorithm. 相似文献16.
Objective
To identify challenges in mapping internal International Classification of Disease, 9th edition, Clinical Modification (ICD-9-CM) encoded legacy data to Systematic Nomenclature of Medicine (SNOMED), using SNOMED-prescribed compositional approaches where appropriate, and to explore the mapping coverage provided by the US National Library of Medicine (NLM)''s SNOMED clinical core subset.Design
This study selected ICD-CM codes that occurred at least 100 times in the organization''s problem list or diagnosis data in 2008. After eliminating codes whose exact mappings were already available in UMLS, the remainder were mapped manually with software assistance.Results
Of the 2194 codes, 784 (35.7%) required manual mapping. 435 of these represented concept types documented in SNOMED as deprecated: these included the qualifying phrases such as ‘not elsewhere classified’. A third of the codes were composite, requiring multiple SNOMED code to map. Representing 45 composite concepts required introducing disjunction (‘or’) or set-difference (‘without’) operators, which are not currently defined in SNOMED. Only 47% of the concepts required for composition were present in the clinical core subset. Search of SNOMED for the correct concepts often required extensive application of knowledge of both English and medical synonymy.Conclusion
Strategies to deal with legacy ICD data must address the issue of codes created by non-taxonomist users. The NLM core subset possibly needs augmentation with concepts from certain SNOMED hierarchies, notably qualifiers, body structures, substances/products and organisms. Concept-matching software needs to utilize query expansion strategies, but these may be effective in production settings only if a large but non-redundant SNOMED subset that minimizes the proportion of extensively pre-coordinated concepts is also available. 相似文献17.
Background and objective
Providing patients access to their medical records offers many potential benefits including identification and correction of errors. The process by which patients ask for changes to be made to their records is called an ‘amendment request’. Little is known about the nature of such amendment requests and whether they result in modifications to the chart.Methods
We conducted a qualitative content analysis of all patient-initiated amendment requests that our institution received over a 7-year period. Recurring themes were identified along three analytic dimensions: (1) clinical/documentation area, (2) patient motivation for making the request, and (3) outcome of the request.Results
The dataset consisted of 818 distinct requests submitted by 181 patients. The majority of these requests (n=636, 77.8%) were made to rectify incorrect information and 49.7% of all requests were ultimately approved. In 6.6% of the requests, patients wanted valid information removed from their record, 27.8% of which were approved. Among all of the patients requesting a copy of their chart, only a very small percentage (approximately 0.2%) submitted an amendment request.Conclusions
The low number of amendment requests may be due to inadequate awareness by patients about how to make changes to their records. To make this approach effective, it will be important to inform patients of their right to view and amend records and about the process for doing so. Increasing patient access to medical records could encourage patient participation in improving the accuracy of medical records; however, caution should be used. 相似文献18.

Objectives
To determine the frequency with which computerized alerts occur and the proportion triggered as a result of prescribers not utilizing e-prescribing system functions.Methods
An audit of electronic inpatient medication charts at a teaching hospital in Sydney, Australia, was conducted to identify alerts fired, to categorize the system functions used by prescribers, and to assess if use of short-cut system functions could have prevented the alerts.Results
Of the 2209 active orders reviewed, 600 (27.2%) triggered at least one alert. Therapeutic duplication alerts were the most frequent (n=572). One third of these (20.2% of all alerts) was ‘technically preventable’ and would not have fired if prescribers had used a short-cut system function to prescribe. Under-utilized system functions included the option to ‘MODIFY’ existing orders and use of the ‘AND’ function for concurrent orders. Pregnancy alerts, set for women aged between 12 and 55 years, were triggered for 43% of drugs ordered for this group.Conclusion
Developers of decision support systems should test the extent to which technically preventable alerts may arise when prescribers fail to use system functions as designed. Designs which aim to improve the efficiency of the prescribing process but which do not align with the cognitive processes of users may fail to achieve this desired outcome and produce unexpected consequences such as triggering unnecessary alerts and user frustration. Ongoing user training to support effective use of e-prescribing system functions and modifications to the mechanisms underlying alert generation are needed to ensure that prescribers are presented with fewer but more meaningful alerts. 相似文献19.
Objective
To foster informed decision-making about health social networking (SN) by patients and clinicians, the authors evaluated the quality/safety of SN sites'' policies and practices.Design
Multisite structured observation of diabetes-focused SN sites.Measurements
28 indicators of quality and safety covering: (1) alignment of content with diabetes science and clinical practice recommendations; (2) safety practices for auditing content, supporting transparency and moderation; (3) accessibility of privacy policies and the communication and control of privacy risks; and (4) centralized sharing of member data and member control over sharing.Results
Quality was variable across n=10 sites: 50% were aligned with diabetes science/clinical practice recommendations with gaps in medical disclaimer use (30% have) and specification of relevant glycosylated hemoglobin levels (0% have). Safety was mixed with gaps in external review approaches (20% used audits and association links) and internal review approaches (70% use moderation). Internal safety review offers limited protection: misinformation about a diabetes ‘cure’ was found on four moderated sites. Of nine sites with advertising, transparency was missing on five; ads for unfounded ‘cures’ were present on three. Technological safety was poor with almost no use of procedures for secure data storage and transmission; only three sites support member controls over personal information. Privacy policies'' poor readability impedes risk communication. Only three sites (30%) demonstrated better practice.Limitations
English-language diabetes sites only.Conclusion
The quality/safety of diabetes SN is variable. Observed better practice suggests improvement is feasible. Mechanisms for improvement are recommended that engage key stakeholders to balance autonomy, community ownership, conditions for innovation, and consumer protection. 相似文献20.
