Use of email in a family practice setting: opportunities and challenges in patient- and physician-initiated communication.

BACKGROUND: Electronic mail (email) has the potential to improve communication between physicians and patients. METHODS: We conducted two research studies in a family practice setting: 1) a brief, anonymous patient survey of a convenience sample to determine the number of clinic patients receptive to communicating with their physician via email, and 2) a randomized, controlled pilot study to assess the feasibility of providing health education via email to family practice patients. RESULTS: Sixty-eight percent of patients used email, and the majority of those (80%) were interested in using email to communicate with the clinic. The majority also reported that their email address changed less frequently than their home address (65%, n = 173) or telephone number (68%, n = 181). Forty-two percent were willing to pay an out-of-pocket fee to have email access to their physicians. When evaluating email initiated by the clinic, 26% of otherwise eligible patients could not participate because they lacked email access; those people were more likely to be black and to be insured through Medicaid. Twenty-four subjects agreed to participate, but one-third failed to return the required consent form by mail. All participants who received the intervention emails said they would like to receive health education emails in the future. CONCLUSION: Our survey results show that patients are interested in email communication with the family practice clinic. Our feasibility study also illustrates important challenges in physician-initiated electronic communication. The 'digital divide' - decreased access to electronic technologies in lower income groups - is an ethical concern in the use of email for patient-physician communication.

Interpretation of congruent and incongruent affective communications in paranoid schizophrenia.

OBJECTIVES: It was hypothesized that people with paranoid schizophrenia would differ from depressed and normal participants in their interpretation of complex communications in which the affect conveyed verbally was either congruent or incongruent with the affect conveyed non-verbally. DESIGN: A 3 (group) x 3 (positive, negative, neutral facial expression) x 3 (positive, negative, neutral verbal content) experimental design was used. There were eight participants per group, and the paranoid and depressed groups comprised inpatients in an acute psychiatric facility for either their first or second psychiatric episode. METHODS: Participants, tested individually, were asked to interpret the affect conveyed by the various communications presented. RESULTS: All participants interpreted most of the communications in a similar way. Paranoid schizophrenia patients, however, differed in their interpretation of communications in which negative feelings were expressed verbally. In contrast to both the normal and depressed groups, the paranoid schizophrenia group interpreted these communications as virtually devoid of any affect whatsoever. CONCLUSIONS: Paranoid schizophrenia patients show an information-processing bias in response to communications involving both congruent and incongruent negative verbal content. It is not obvious why the bias observed would be specific to negative verbal messages and not extend to negative non-verbal messages. Replication and further study are required.

Linear optoacoustic underwater communication.

The linear mechanism for optical-to-acoustic energy conversion is explored for optoacoustic communication from an in-air platform or surface vessel to a submerged vessel such as a submarine or unmanned undersea vehicle. The communication range that can be achieved is addressed. A number of conventional signals used in underwater acoustic telemetry applications are shown to be capable of being generated experimentally through the linear optoacoustic regime conversion process. These results are in agreement with simulation based on current theoretical models. A number of practical issues concerning linear optoacoustic communication are addressed that lead to a formulation of a linear-regime optoacoustic communication scheme. The use of oblique laser beam incidence at the air-water interface to obtain considerable in-air range from the laser source to the in-water receiver is addressed. Also, the effect of oblique incidence on in-water range is examined. Next, the optimum and suboptimum linear optoacoustic sound-generation techniques for selecting the optical wavelength and signaling frequency for optimizing in-water range are addressed and discussed. Optoacoustic communication techniques employing M-ary frequency shift keying and multifrequency shift keying are then compared with regard to communication parameters such as bandwidth, data rate, range coverage, and number of lasers employed.

[The critical patient and communication: the vision of the family regarding the nursing team].

Communication is considered an important variable in the care of critical patients and their families, whose difficulty concerning communication is expressed in the literature. The purpose of this survey was to verify what is considered adequate communication with the nursing team in the perception of the critical patient's family. This is an exploratory and field study carried out at the Intensive Care Unit of the University of São Paulo's Hospital Universitário. The population surveyed was comprised of 13 relatives of critical patients. The data was collected in November of 2003 and analyzed according to Bardin proposal. Communication was considered adequate when it was a means for information - the information was clear and objective, doubts were clarified, orientation was provided and communication was a form of humanizing health care - and there was verbal communication even when the patient was sedated, with somebody as a reference whom the relatives could resort to.

An Internet-based patient-provider communication system: randomized controlled trial.

BACKGROUND: Internet-based interactive websites for patient communication (patient portals) may improve communication between patients and their clinics and physicians. OBJECTIVE: The aim of the study was to assess the impact of a patient portal on patients' satisfaction with access to their clinic and clinical care. Another aim was to analyze the content and volume of email messages and telephone calls from patients to their clinic. METHODS: This was a randomized controlled trial with 606 patients from an academic internal medicine practice. The intervention "portal" group used a patient portal to send secure messages directly to their physicians and to request appointments, prescription refills, and referrals. The control group received usual care. We assessed patient satisfaction at the end of the 6-month trial period and compared the content of telephone and portal communications. RESULTS: Portal group patients reported improved communication with the clinic (portal: 77/174 [44%] "a little better" or "a lot better;" control: 18/146 [12%]; chi2 = 38.8, df = 1, P < .001) and higher satisfaction with overall care (portal: 103/174 [59%] "very good" or "excellent;" control: 78/162 [48%]; chi2 = 4.1, df = 1, P = .04). Portal group patients also reported higher satisfaction with each of the portal's services. Physicians received 1 portal message per day for every 250 portal patients. Total telephone call volume was not affected. Patients were more likely to send informational and psychosocial messages by portal than by phone. Of all surveyed patients, 162/341 (48%) were willing to pay for online correspondence with their physician. Of those willing to pay, the median amount cited was 2 USD per message. CONCLUSIONS: Portal group patients demonstrated increased satisfaction with communication and overall care. Patients in the portal group particularly valued the portal's convenience, reduced communication barriers, and direct physician responses. More online messages from patients contained informational and psychosocial content compared to telephone calls, which may enhance the patient-physician relationship.

Imaging-guided catheter drainage of abdominal collections with fistulous pancreaticobiliary communication.

OBJECTIVE: Our aim was to study the success of percutaneous imaging-guided catheter drainage of abdominal collections with documented fistulous pancreaticobiliary communication. MATERIALS AND METHODS: Fifty-seven patients (age range, 23-88 years) with abdominal collections who underwent imaging-guided catheter drainage were included in this retrospective study. These collections showed communication with either the pancreatic duct (n = 15) or the biliary duct (n = 42) on imaging. The imaging guidance included CT (n = 40), sonography (n = 17), and fluoroscopy (n = 4), either alone or in combination. The success of catheter drainage was described as resolution of the collection on follow-up imaging and clinical improvement. Other treatments directed toward management of leaks or collections were also recorded. RESULTS: The success rates of catheter drainage for abdominal collections with biliary and pancreatic ductal communication were 93% (39/42) and 67% (10/15), respectively. The difference was statistically significant (p = 0.01). The three complications seen in this study were pneumothorax in one patient, bowel perforation in one, and death in one. The drainage catheter was upsized in five patients and an additional catheter was needed in nine patients. CONCLUSION: Imaging-guided catheter drainage is a clinically useful option for drainage of abdominal collections that have pancreaticobiliary communications. The success rate is significantly better for collections with biliary communication than for those with pancreatic communication.

Analysis of motor fibers in the communicating branch between the cervical nerves and the spinal accessory nerve to innervate trapezius in the rat.

The communicating branch between the ventral rami of cervical nerves and the spinal accessory nerve (SAN) has been reported to also send motor fibers to supply the trapezius. However, the motor fiber type of the communicating branch and its peripheral distribution are still unclear. To determine the fiber elements within the branch and its peripheral distribution of the motor fibers in the trapezius, the anterograde tracing method was used in this study. The results show that a few a motor end plates from the communicating branch were observed on the extrafusal fibers, while in the muscle spindle the motor elements from the communicating branch were distributed to the polar portions of the intrafusal fibers. These results indicated that the motor fibers passing through the communicating branch to supply the trapezius are mainly y motor fibers, with some a motor fibers. Moreover, the a and y motor fibers from the communicating branch were observed in the clavotrapezius, acromiotrapezius and the rostral part of spinotrapezius. These findings also correlate with the clinical observation indicating that even when the spinal accessory nerve is injured, the trapezius is still capable of slight movement.

Enhancing doctor-patient communication using email: a pilot study.

BACKGROUND: The doctor-patient relationship has been eroded by many factors. Would e-mail enhance communication and address some of the barriers inherent to our medical practices? METHODS: Of our study population, 4 physicians offered e-mail communication to participating patients and 4 did not. Both patients and physicians completed questionnaires regarding satisfaction, perceived quality, convenience, and promptness of the communication. RESULTS: Patient satisfaction significantly increased in the e-mail group compared with the control group in the areas of convenience (P < .0001) and the amount of time spent contacting their physician (P < .0001). Physician satisfaction in the e-mail group increased regarding convenience, amount of time spent on messages, and volume of messages. The response time was longer with e-mail. When asked if patients should be able to e-mail their physicians, most patients in the e-mail group and all but 2 of the physicians in the non-e-mail group responded "yes." CONCLUSION: E-mail communication was found to be a more convenient form of communication. Satisfaction by both patients and physicians improved in the e-mail group. The volume of messages and the time spent answering messages for the e-mail group physicians was not increased. E-mail has the potential to improve the doctor-patient relationship as a result of better communication.

Cerebral blood flow and ICP patterns in patients with communicating hydrocephalus after aneurysm rupture.

Cerebral blood flow (CBF) was measured, the intracranial pressure (ICP) was continuously recorded, and the ventricular system size was evaluated on serial computerized tomography scans in 43 patients. These patients all had communicating hydrocephalus after subarachnoid hemorrhage (SAH) from rupture of an intracranial aneurysm. The studies were carried out both in the acute stage (within 7 days after SAH) and in the communicating hydrocephalus stage. In patients in the acute stage who had no ventricular dilatation, but who later developed communicating hydrocephalus, the mean CBF was reduced; lower CBF was associated with poorer clinical grades and a higher resting pressure range. Communicating hydrocephalus produced a significant decrease in CBF. The ICP tracing showed continuing plateau waves in conjunction with B-waves in patients in whom recordings were begun within 63 days after SAH. In general, patients with more dilated ventricular systems, with less frequent ICP irregularities, and with lower resting pressure ranges had a more marked decrease in CBF. A significant decrease in CBF was also found in patients with diffuse vasospasm in comparison to those without vasospasm. Patients with communicating hydrocephalus in whom ICP recordings were started more than 6 months after SAH showed no ICP irregularities. In these patients, a mean CBF of less than 25 ml/100 gm/min and a markedly low resting pressure range were observed. Shunting procedures were never effective in any of these patients. The results suggest that, in patients with communicating hydrocephalus, a mean CBF below this level may cause irreversible damage to the brain tissue in the terminal stage, and may inhibit the cerebral vasomotor reaction that participates in the development of ICP irregularities.

Communication between malignant glioma cells and vascular endothelial cells through gap junctions.

OBJECT: Extensive invasion and angiogenesis are hallmark features of malignant gliomas. Communication between malignant glioma cells and surrounding astrocytes occurs, resulting in transformation of the astrocytic phenotype. In the present study, the authors examined whether malignant glioma cells and vascular endothelial cells (VECs) communicate through the formation of gap junctions and whether this communication influences angiogenesis. METHODS: Connexin43 (Cx43), a gap junction protein expressed in glioma cells, was identified in human umbilical VECs (HUVECs). Immunocytochemical staining for Cx43 demonstrated immunoreactive plaques at areas of cell-cell contact among HUVECs as well as between HUVECs and Cx43-expressing malignant glioma cells. Dye transfer, performed using the gap junction-permeable dye dicarboxy-dichlorofluorescein diacetate (CDCF), among these cocultures indicated that these were functional communications. Calcium signaling also occurred from malignant glioma cells to HUVECs. Tube formation by HUVECs cocultured with Cx43-transfected T98G malignant glioma cells (T98G-Cx43 cells) or with U87MG malignant glioma cells, which naturally express Cx43, was significantly increased compared with tube formation by HUVECs alone. The difference in tube formation by HUVECs cocultured with empty vector-transfected T98G glioma cells (T98G-mock cells) or with Cx43-deficient U373MG malignant glioma cells and tube formation by HUVECs alone was not statistically significant. Furthermore, the concentration of vascular endothelial growth factor (VEGF), an angiogenic factor important for the induction of angiogenesis and blood vessel formation, was significantly higher in medium harvested from cultures of T98G-Cx43 cells than in that harvested from cultures of control T98G-mock cells. Human malignant glioma U87MG cells also secreted increased concentrations of VEGF as compared with HUVECs alone. Nevertheless, there was no statistically significant difference in tube formation by HUVECs cultured in medium conditioned by either Cx43-expressing or Cx43-deficient glioma cells, suggesting that the direct gap junction communication between glioma cells and HUVECs may play a much more significant role than the increased VEGF secretion in vascular tube formation in this assay. CONCLUSIONS: These results indicate that functional gap junction formation between human malignant glioma cells and VECs occurs. This communication appears to influence tumor angiogenesis. Targeting gap junction signaling may offer a potential mechanism for therapy in patients with these tumors.

Prenatal diagnosis of ventriculocoronary arterial communication in fetuses with hypoplastic left heart syndrome.

OBJECTIVE: The purpose of this series was to describe the fetal echocardiographic findings in hypoplastic left heart syndrome with aortic atresia and ventriculocoronary arterial communication and implications of these findings. METHODS: We describe 2 fetuses with hypoplastic left heart syndrome with ventriculocoronary arterial communication diagnosed at 29 and 20 weeks' gestation, respectively. The underlying cardiac anatomy consisted of a hypoplastic left heart and mitral stenosis with aortic atresia. We used color Doppler and pulsed Doppler sonography on the surface of the myocardium to specifically look for coronary arterial flow. RESULTS: By color Doppler sonography, ventriculocoronary arterial communication was shown between the left ventricular cavity and the left coronary artery with characteristic bidirectional flow on pulsed Doppler examination. There was no mitral regurgitation. The left ventricular myocardium was substantially hypertrophied. The first patient underwent surgical Norwood palliation and died after a prolonged postoperative course. The second patient underwent stenting of the arterial duct and bilateral pulmonary artery banding in the catheterization laboratory but died after a few weeks. Implications of ventriculocoronary arterial communication in association with hypoplastic left heart syndrome are discussed. CONCLUSIONS: It is possible to accurately diagnose ventriculocoronary arterial communication on fetal echocardiography. The presence of ventriculocoronary arterial communication is seen exclusively in a subgroup of patients with an aortic atresia and mitral stenosis variant of hypoplastic left heart syndrome. The prognosis is poor in this subgroup of patients.

Architecture models to facilitate communication of clinical information.

This is an account of the development and use of a context model for facilitating the communication of clinical information. Its function is to articulate the principle of context within a reference architecture for the Electronic Health Care Record (EHCR). The work required a re-examination of established models of communication, the purpose being to use them to support an architecture that could be reasonably expected to accommodate future, and by definition unforeseeable, developments in EHCR communication. The Context Model is built upon seven recognized constituents of communication. These constituents, although having their origin in the engineering of signal communication, have been found to be useful for explication both in the verbal and textual communication of narratives between people. The electronic health care record architecture supported by the model is the European prestandard ENV13606-1.

[Structural peculiarities of the human cerebral communicating arteries and their repercussion in encephalic vascular pathology].

INTRODUCTION: The cerebrovascular accidents are one of the most frequent causes of morbimortality. Most of them are caused for the break of aneurysms in communicating arteries. The weak structure of these vessels explain the reason of these accidents. OBJECTIVE: The reason of this paper is study the organization of communicating arteries as cause of this fragility. Material and methods. The material of this study is composed of 61 human cerebral communicating arteries, grouped in decades. The study has been carried out by histological routine. RESULTS: In general the structure of cerebral communicating arteries is characterized for the thinness and irregularity of the wall. In the childhood the internal elastic membrane and tunica media show thicker, while in young and adult people appear elastic fibers and reticulin as well as smooth muscle cells in tunica media. In adulthood (50 60 years) collagen in adventicia occupies tunica media, and adventicia is weaked. There are frequent media defects in these communicating arteries, that are usually repaired for conjunctive tissue stopper with abundance of collagen fibers. Starting from 4th decade the internal elastic membrane shows a great number of fenestrae through muscle and fiber tissue of media occupying subintimal space. Doubtless media defects mean the most severe threat of vascular outbreak. CONCLUSION: The structural evolution with the age of communicating arteries, with predominance of collagen over elastin and reticulin, could be their reason of fragility.

Influence of different stages of the oestrous cycle on cumulus-oocyte communications in canine oocytes: effects on the efficiency of in vitro maturation.

The aim of this study was to investigate the effects of different stages of the oestrous cycle on the communications between dog oocytes and cumulus cells, as well as their possible relationships with the meiotic competence of oocytes matured in vitro. Ovaries were harvested from bitches undergoing anoestrus or late pro-oestrus. Maturation of cumulus-oocyte complexes (COCs) was performed in TCM-199 with 0.3% (w/v) BSA, 0.5 iu FSH ml-1 and 0.5 iu LH ml-1 for 72 h. At the time of collection (0 h), and after 24, 48 or 72 h of culture, some oocytes were stained with Lacmoid to evaluate the nuclear stage of maturation. At 0, 24 or 48 h of in vitro maturation (IVM), oocytes were microinjected (n = 84) with a 3% (w/v) Lucifer yellow solution to evaluate the presence of cumulus-oocyte communications through gap junctions. At t = 0, communications were open in 89% of COCs collected during late pro-oestrus, whereas such communications were not evident in any of the oocytes collected during anoestrus. Communications remained permeable for the first 24 h of maturation in many late pro-oestrous oocytes (67%), whereas no fluorescence diffusion was observed at 48 h of maturation. The presence of cumulus-oocyte communications in late pro-oestrous oocytes was accompanied by their ability to resume meiosis and reach telophase I or metaphase II at higher rates than in oocytes collected during anoestrus (11.1% versus 0%, respectively; P < 0.01). These results indicate that, during anoestrus, there are no permeable gap junctions between oocytes and surrounding cumulus cells at the time of isolation from the ovary. This finding indicates that such oocytes are unsuitable for IVM, as confirmed by their inability to reach telophase I or metaphase II in culture. In contrast, a positive correlation was observed between the presence of permeable gap junctions and meiotic competence in COCs isolated at late pro-oestrus. However, the small proportion of oocytes reaching telophase I and metaphase II indicates that further efforts to define better culture conditions are still required.

[Adjustable interatrial communication in management of severe congenital heart disease].

OBJECTIVE: To assess the use of adjustable interatrial communication in patient with severe congenital heart disease undergoing open heart surgery. METHODS: From February 1998 to June 1999, 13 patients with severe and complex congenital heart disease underwent open heart surgery. Seven patients underwent total cavopulmonary connection, five patients repair of Ebstein's anomaly, and one patient right atrial-pulmonary connection. Adjustable interatrial communication was made in all patients. Four patients had the communication closed at the time of operation, 4 patients had the communication opened at the time of operation, and 5 patients had the communication adjusted and closed postoperatively. RESULTS: All patients had a smooth postoperative process. There were no postoperative death and no severe postoperative complications. CONCLUSION: Adjustable interatrial communication for the patients undergoing modified Fontan procedure or correction of Ebstein's anomaly may be advantageous.

[Communication and language in the autistic spectrum: autism and dysphasia].

INTRODUCTION: The alterations of language and communication seen in children with autistic spectrum disorders (TEA) have some similar and some dissimilar features to those seen in children with specific language disorders (TEL). The basic disorder of TEA seems to be due to alterations in the social and mental use of codes of communication, both verbal and non verbal. Children with TEL however have better non verbal and practical abilities. OBJECTIVE: In view of this, we decided to determine the qualitative difference in function in communication and language between the two populations. PATIENTS AND METHODS: The great heterogeneity between persons with autistic spectrum disorders and even variation between individuals makes investigation of large groups difficult. It is therefore necessary to study individual cases or groups with small numbers. If we fix our attention on language and communication, it is important to define subtypes of function with the population affected by the autistic spectrum of disorders at an early age, in the fields of communication, receptive language and expressive language in our small sample of persons; taking the normal course of development in each field as the parameter for comparison. This is a pilot study within a long term research project. RESULTS: The results reported here are the preliminary findings of what will be a more extensive study with fuller analysis of the results. CONCLUSIONS: The preliminary findings suggest that there are different linguistic and communication function profiles in the different populations compared.

Husband-wife communication and family planning practices among Malay married couples in Mukim Rusila, Terengganu.

The role of husband-wife communication in the practice of family planning was studied among the rural Malay couples in Mukim Rusila, Terengganu. It was a cross-sectional study in which a cluster sampling was used to select the study sample. A total of 193 (100.0%) wives and 74 (38.3%) husbands responded to a face-to-face interview. Visual Analogue Scale was used to measure the level of husband-wife communication. Husband-wife communication score was lower on family planning compared to other matters. There was a significant fair agreement on the scores between the husbands and the wives (p > 0.05) on family planning. There was a significant association between husband-wife communication on family planning and the current practice of family planning (p = 0.002). The 'likelihood' that couples who had had good husband-wife communication to practice family planning was about 2.8 times higher compared to those couples with poor husband-wife communication (95% C.I.: 1.4, 5.3). Further research need to be carried out, as the study was limited by certain constraints.

[A study on the communication between the pectoral nerve and the extramural nerve branches of the intercostal nerves].

Kumaki et al. (1979) defined the extramural nerve as the rudimentary sensory nerve which appeared on the upper thoracic wall; it branched off the root of the lateral cutaneous nerve of the second, third or fourth intercostal nerve, ran inferomedially adhering to the fascia of the intercostalis externus muscle and ended supplying the membrane covering the adjacent rib. They also stated that the extramural nerve (Rxm) occasionally became a cutaneous nerve which pierced the pectoralis muscles and supplied the skin covering the thoracic wall similar to the lateral cutaneous nerve (Rcl) or the anterior cutaneous nerve (Rca). Further, they proposed that the muscular nerves to the obliquus externus abdominis muscle which are usually situated below the fifth rib might be considered a part of this Rxm series. Although the definition of Rxm is still not widely accepted, Rxm is thought to be a key morphological factor influencing the variations of peripheral nerve arrangement on the thoracic wall. In the student course of gross anatomy dissection at Iwate Medical University School of Medicine during the years 1987-1991, three cases of Rxm communicating with the pectoral nerve and supplying the pectoralis major muscle were observed. Some cases have been reported in which Rcl innervates part of the pectoral muscles. However, the communication between the pectoral nerve and Rxm has not yet been discussed. Therefore, to clarify the morphological significance of the communication between Rxm and the pectoral nerve, the branching pattern and the distribution of the pectoral nerves were extensively investigated and the intramuscular nerve supply of some pectoral nerves, especially the pectoral nerves which communicated with Rxm, was examined in detail under a stereomicroscope. The results are summarized as follows: 1. In the first case, Rxm of the second intercostal nerve originated from Rcl, ran inferomedially adhering to the fascia of the intercostalis externus muscle and pierced the origin of the pectoralis minor muscle at the third intercostal space. Then Rxm turned superolaterally to communicate with a pectoral nerve which originated from the loop composed of the lateral and medial pectoral nerves and passed inferior to the pectoralis minor muscle. After communication, the pectoral nerve with Rxm supplied the caudalmost part of the sternocostal portion of the pectoralis major muscle. In the second case, a similar branch of Rxm of the second intercostal nerve passed inferior to the pectoralis minor muscle.(ABSTRACT TRUNCATED AT 400 WORDS)
