Gaps in governance: protective mechanisms used by nurse leaders when policy and practice are misaligned

BACKGROUND

Due to large geographical distances, the telephone is central to enabling rural Australian communities to access care from their local health service. While there is a history of rural nurses providing care via the telephone, it has been a highly controversial practice that is not routinely documented and little is known about how the practice is governed. The lack of knowledge regarding governance extends to the role of Directors of Nursing as clinical leaders charged with the responsibility of ensuring practice safety, quality, regulation and risk management. The purpose of this study was to identify clinical governance processes related to managing telephone presentations, and to explore Directors of Nursing perceptions of processes and clinical practices related to the management of telephone presentations to health services in rural Victoria, Australia.

METHODS

Qualitative documentary analysis and semi structured interviews were used in the study to examine the content of health service policies and explore the perceptions of Directors of Nursing in eight rural health services regarding policy content and enactment when people telephone rural health services for care. Participants were purposively selected for their knowledge and leadership role in governance processes and clinical practice. Data from the interviews were analysed using framework analysis. The process of analysis resulted in the identification of five themes.

RESULTS

The majority of policies reviewed provided little guidance for managing telephone presentations. The Directors of Nursing perceived policy content and enactment to be largely inadequate. When organisational structures failed to provide appropriate governance for the context, the Directors of Nursing engaged in protective mechanisms to support rural nurses who manage telephone presentations.

CONCLUSIONS

Rural Directors of Nursing employed intuitive behaviours to protect rural nurses practicing within a clinical governance context that is inadequate for the complexities of the environment. Protective mechanisms provided indicators of clinical leadership and governance effectiveness, which may assist rural nurse leaders to strengthen quality and safe care by unlocking the potential of intuitive behaviours. Kanter's theory of structural power provides a way of conceptualising these protective mechanisms, illustrating how rural nurse leaders enact power.

Telephone support for women during pregnancy and the first six weeks postpartum

BACKGROUND

Telephone communication is increasingly being accepted as a useful form of support within health care. There is some evidence that telephone support may be of benefit in specific areas of maternity care such as to support breastfeeding and for women at risk of depression. There is a plethora of telephone-based interventions currently being used in maternity care. It is therefore timely to examine which interventions may be of benefit, which are ineffective, and which may be harmful.

OBJECTIVES

To assess the effects of telephone support during pregnancy and the first six weeks post birth, compared with routine care, on maternal and infant outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (23 January 2013) and reference lists of all retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials, comparing telephone support with routine care or with another supportive intervention aimed at pregnant women and women in the first six weeks post birth.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed studies identified by the search strategy, carried out data extraction and assessed risk of bias. Data were entered by one review author and checked by a second. Where necessary, we contacted trial authors for further information on methods or results.

MAIN RESULTS

We have included data from 27 randomised trials involving 12,256 women. All of the trials examined telephone support versus usual care (no additional telephone support). We did not identify any trials comparing different modes of telephone support (for example, text messaging versus one-to-one calls). All but one of the trials were carried out in high-resource settings. The majority of studies examined support provided via telephone conversations between women and health professionals although a small number of trials included telephone support from peers. In two trials women received automated text messages. Many of the interventions aimed to address specific health problems and collected data on behavioural outcomes such as smoking cessation and relapse (seven trials) or breastfeeding continuation (seven trials). Other studies examined support interventions aimed at women at high risk of postnatal depression (two trials) or preterm birth (two trials); the rest of the interventions were designed to offer women more general support and advice.For most of our pre-specified outcomes few studies contributed data, and many of the results described in the review are based on findings from only one or two studies. Overall, results were inconsistent and inconclusive although there was some evidence that telephone support may be a promising intervention. Results suggest that telephone support may increase women's overall satisfaction with their care during pregnancy and the postnatal period, although results for both periods were derived from only two studies. There was no consistent evidence confirming that telephone support reduces maternal anxiety during pregnancy or after the birth of the baby, although results on anxiety outcomes were not easy to interpret as data were collected at different time points using a variety of measurement tools. There was evidence from two trials that women at high risk of depression who received support had lower mean depression scores in the postnatal period, although there was no clear evidence that women who received support were less likely to have a diagnosis of depression. Results from trials offering breastfeeding telephone support were also inconsistent, although the evidence suggests that telephone support may increase the duration of breastfeeding. There was no strong evidence that women receiving telephone support were less likely to be smoking at the end of pregnancy or during the postnatal period.For infant outcomes, such as preterm birth and infant birthweight, overall, there was little evidence. Where evidence was available, there were no clear differences between groups. Results from two trials suggest that babies whose mothers received support may have been less likely to have been admitted to a neonatal intensive care unit (NICU), although it is not easy to understand the mechanisms underpinning this finding.

AUTHORS' CONCLUSIONS

Despite some encouraging findings, there is insufficient evidence to recommend routine telephone support for women accessing maternity services, as the evidence from included trials is neither strong nor consistent. Although benefits were found in terms of reduced depression scores, breastfeeding duration and increased overall satisfaction, the current trials do not provide strong enough evidence to warrant investment in resources.

Remote care by telemedicine in the ICU: many models of care can be effective

PURPOSE OF REVIEW

Telemedicine, by the use of audiovisual technologies, is increasingly being used to assist in patient care by ICUs unable to be staffed by consultant intensivists. This review discusses the recent evaluation of these services and their potential role in managing intensive care patients.

RECENT FINDINGS

Models of care range from complete remote 24 h surveillance requiring direct video observation to a consultation liaison service only requiring conventional telephone links. There has been a rapid adoption of such services especially in North America where access to on-site intensive care specialists is limited for the volume of intensive care being undertaken. Early work suggests savings in terms of cost and length of stay with an improvement in compliance with care protocols. However, later work is not as supportive of such services, possibly related to differing care infrastructures and the organization of individual units. The key task is to ascertain the most appropriate service requirements that would assist in care for a given patient circumstance.

SUMMARY

Clear benefits of ICU-telemedicine systems remain unclear but at least the systems appear safe. Formal reviews of the impacts and contribution of ICU telemedicine to processes of care, the effects on unit staffing, hospital organization, and the healthcare region are needed. However, ICU-telemedicine is available and being embraced by some, especially to deal with the tyranny of distance.
