The Effects on Health Behavior and Health Outcomes of Internet-Based Asynchronous Communication Between Health Providers and Patients With a Chronic Condition: A Systematic Review

Background

In support of professional practice, asynchronous communication between the patient and the provider is implemented separately or in combination with Internet-based self-management interventions. This interaction occurs primarily through electronic messaging or discussion boards. There is little evidence as to whether it is a useful tool for chronically ill patients to support their self-management and increase the effectiveness of interventions.

Objective

The aim of our study was to review the use and usability of patient-provider asynchronous communication for chronically ill patients and the effects of such communication on health behavior, health outcomes, and patient satisfaction.

Methods

A literature search was performed using PubMed and Embase. The quality of the articles was appraised according to the National Institute for Health and Clinical Excellence (NICE) criteria. The use and usability of the asynchronous communication was analyzed by examining the frequency of use and the number of users of the interventions with asynchronous communication, as well as of separate electronic messaging. The effectiveness of asynchronous communication was analyzed by examining effects on health behavior, health outcomes, and patient satisfaction.

Results

Patients’ knowledge concerning their chronic condition increased and they seemed to appreciate being able to communicate asynchronously with their providers. They not only had specific questions but also wanted to communicate about feeling ill. A decrease in visits to the physician was shown in two studies (P=.07, P=.07). Increases in self-management/self-efficacy for patients with back pain, dyspnea, and heart failure were found. Positive health outcomes were shown in 12 studies, where the clinical outcomes for diabetic patients (HbA1c level) and for asthmatic patients (forced expiratory volume [FEV]) improved. Physical symptoms improved in five studies. Five studies generated a variety of positive psychosocial outcomes.

Conclusions

The effect of asynchronous communication is not shown unequivocally in these studies. Patients seem to be interested in using email. Patients are willing to participate and are taking the initiative to discuss health issues with their providers. Additional testing of the effects of asynchronous communication on self-management in chronically ill patients is needed.     

Intestinal ischaemia associated with carcinoid tumour: A case report with review of the pathogenesis

A case of ischaemic ileal perforation associated with a macroscopically unapparent ileal carcinoid is described. The mesenteric vessels were non-pulsatile at operation but were anatomically patent when examined by the pathologist. The characteristic elastic perivascular sclerosis of mesenteric vessels, which probably caused a functional vascular obstruction, was only discovered after the histological sections were reviewed. The true incidence of this rare condition may be higher than previously suspected because the perivascular sclerosis can easily be overlooked. Awareness of the association between carcinoid tumour and mesenteric ischaemia may lead to early surgery and an improved outcome.     

Percutaneous Myocardial Laser Revascularization

Transmyocardial laser revascularization (TMR) is an experimental procedure for intractable angina that has demonstrated clinical benefit. The majority of patients who had TMR have significant reduction of angina. TMR has been performed exclusively by thoracic and cardiac surgeons using a handhold CO₂ laser device. The development of a prototype percutaneous device that delivers mid-infrared laser energy (Ho:YAG) through a 9Fr coaxial catheter system recently has been reported. The long-term benefits of this percutaneous approach is being defined in the context of the randomized PACIFIC Trial. The initial follow-up suggested significant relief of angina in the majority of treated patients, and the results are likely to be equal or similar to those of surgical TMR. The safety data of percutaneous myocardial revascularization (PMR) with the CardioGenesis system showed exceedingly low morbidity and mortality.     

Clinical and familial study of arrhythmogenic right ventricular cardiomyopathy

Objective　To explore the characteristics of arrhythmogenic right ventricular cardiomyopathy (ARVC). Methods　Seven patients with arrhythmogenic right ventricular cardiomyopathy and 34 members of three families were studied. All patients and family members underwent history collection, clinical examination, electrocardiogram (ECG), two-dimensional echocardiography (2-DE) and a signal averaging electrocardiogram. Programmed ventricular stimulation was performed in five patients. Results　All patients and family members had normal morphologic characteristics and normal function of the left ventricular by 2-DE. Fourteen persons had abnormal findings indicating ARVC. Five had enlargement of the right ventricular with diffused hypocontractility, eight had thin and systolic bulging in the focal anterior wall with hypokinesia and one had bulging of the inferior wall. Twenty-five persons (seven patients and 18 family members) had abnormal findings in ECG. Positive ventricular late potential was recorded in 13 persons (six patients). Two to three monomorphic ventricular tachycardia (VT) with left bundle branch block (LBBB) configurations were induced in five patients. Ventricular fibrillation was induced in two patients during the electrophysiologic study (EPS). Five patients had very high pacing threshold and/or ineffective pacing in one or many regions of the right ventricle. Two members of one family died suddenly. One member was a dwarf with ARVC. Spontaneous VT with a left bundle branch block (LBBB) configuration was recorded in five patients, polymorphic VT with extremely short coupling interval in one, and premature ventricular complexes with LBBB configuration in 12 (six patients). Conclusion　Our familial study strongly suggests that ARVC may be a hereditary disease and it is helpful in the diagnosis and detection of ARVC. The most common manifestations were abnormal structure and function of the right ventricle and abnormal ECG of repolarization and ventricular arrhythmia which originates from the right ventricle.     

State of the art and recommendationsKangaroo mother care: application in a high‐tech environment

Since Kangaroo Mother Care (KMC) was developed in Colombia in the 1970s, two trends in clinical application emerged. In low income settings, the original KMC model is implemented. This consists of continuous (24 h/day, 7 days/week) and prolonged mother/parent–infant skin‐to‐skin contact; early discharge with the infant in the kangaroo position; (ideally) exclusive breastfeeding; and, adequate follow‐up. In affluent settings, intermittent KMC with sessions of one or a few hours skin‐to‐skin contact for a limited period is common. As a result of the increasing evidence of the benefits of KMC for both infants and families in all intensive care settings, KMC in a high‐tech environment was chosen as the topic for the first European Conference on KMC, and the clinical implementation of the KMC model in all types of settings was discussed at the 7th International Workshop on KMC. Kangaroo Mother Care protocols in high‐tech Neonatal Intensive Care Units (NICU) should specify criteria for initiation, kangaroo position, transfer to/from KMC, transport in kangaroo position, kangaroo nutrition, parents’ role, modification of the NICU environment, performance of care in KMC, and KMC in case of infant instability. Conclusion: Implementation of the original KMC method, with continuous skin‐to‐skin contact whenever possible, is recommended for application in high‐tech environments, although scientific evaluation should continue.     

Nutritional assessment of children with juvenile chronic arthritis

Nutritional assessment was performed in 38 children with juvenile chronic arthritis (polyarticular [15]; pauciarticular [13]; systemic [10]). This included anthropometric measurements (height, weight, mid-upper arm circumference and four skinfolds) and a 7 day weighed food record. The children were classified according to current type of arthritis which in some cases was not the same as the initial onset type. Mean height Z scores were significantly below the Z score population mean of 0 in the systemic (P = 0.02) and polyarticular (P = 0.009) groups. Mean weight Z scores were also below the mean in the polyarticular group (P = 0.001) but the systemic group did not reach significance. Mean energy intakes were significantly below the recommended dietary intake (RDI) in the systemic (P = 0.01) and polyarticular (P = 0.001) groups. Mean intakes of calcium and zinc were below the RDI of 100% in the polyarticular group (P = 0.0001). Thirteen (34%) of children were taking some form of self-prescribed vitamin and/or mineral supplement. Vitamin C was the most commonly used supplement, despite dietary intakes greatly exceeding the RDI. Nutritional assessment is essential in the management of patients with JCA, in particular those with systemic or polyarticular disease.     

Early Intravenous Indomethacin Prolongs Respiratory Support in Very Low Birth Weight Infants

ABSTRACT. Infants weighing 1500 g at birth requiring either intermittent positive pressure ventilation or continuous positive airway pressure by 12 hours of age were entered in a randomized double blind controlled trial to test the efficacy of early intravenous indomethacin therapy in preventing chronic pulmonary disease of prematurity. Of the 30 newborns enrolled, 15 were treated with indomethacin and 15 were treated with placebo at 12, 24 and 36 hours of age. The groups were similar for birth weight, gestational age, sex, hyaline membrane disease and intracranial hemorrhage. Infants in the placebo group were successfully weaned from intermittent positive pressure ventilation at an earlier age than infants in the indomethacin group ( p <0.05). Furthermore, chronic pulmonary disease of prematurity was similar in the two groups despite a reduction in the incidence of patent ductus arteriosus in the indomethacin group.
