Understanding how rapid response systems may improve safety for the acutely ill patient: learning from the frontline

Introduction Rapid response systems (RRSs) have been introduced to facilitate effective ‘rescue’ of seriously ill patients on hospital wards. While research has demonstrated some benefit, uncertainty remains regarding impact on patient outcomes. Little is known about the relationship between social contexts and the application of the RRS. Design This comparative case study of the RRS within the medical services of two UK hospitals used ethnographic methods over a 12-month period in 2009, including observation (ward work and shadowing medical staff = 150 h), interviews with doctors, ward and critical care nurses, healthcare assistants, safety leads and managers (n=35), documentary review and analysis of routine data. Data were analysed using NVivo software. Results The RRS reduced variability in recording, recognition and response behaviour. The RRS formalised understandings of deterioration and provided a mandate for escalating care across professional and hierarchical boundaries. However, markers of deterioration not assimilated into risk scores were marginalised and it was harder for staff to escalate care without the ‘objective evidence’ provided by the score. Contextual features (eg, leadership, organisational culture and training) shaped implementation, utilisation and impact of the RRS. Reporting and feedback of audit data enabled learning about ‘selected’ escalation work on the wards. Difficulties with referral upwards and across medical boundaries were reported by junior medical staff. Conclusion Locating a RRS within a pathway of care for the acutely ill patient illustrates the role of these safety strategies within the social organisation of clinical work. There is a need to broaden the focus of inquiry from detection and initiation of escalation (where the strategies are principally directed) towards team response behaviour and towards those medical response practices which to date have escaped scrutiny and monitoring.

Women's safety alerts in maternity care: is speaking up enough?

Patients’ contributions to safety include speaking up about their perceptions of being at risk. Previous studies have found that dismissive responses from staff discouraged patients from speaking up. A Care Quality Commission investigation of a maternity service where serious incidents occurred found evidence that women had routinely been ignored and left alone in labour. Women using antenatal services hesitated to raise concerns that they felt staff might consider irrelevant. The Birthplace in England programme, which investigated the quality and safety of different places of birth for ‘low-risk’ women, included a qualitative organisational case study in four NHS Trusts. The authors collected documentary, observational and interview data from March to December 2010 including interviews with 58 postnatal women. A framework approach was combined with inductive analysis using NVivo8 software. Speaking up, defined as insistent and vehement communication when faced with failure by staff to listen and respond, was an unexpected finding mentioned in half the womens interviews. Fourteen women reported raising alerts about safety issues they felt to be urgent. The presence of a partner or relative was a facilitating factor for speaking up. Several women described distress and harm that ensued from staff failing to listen. Women are speaking up, but this is not enough: organisation-focused efforts are required to improve staff response. Further research is needed in maternity services and in acute and general healthcare on the effectiveness of safety-promoting interventions, including real-time patient feedback, patient toolkits and patient-activated rapid response calls.

Value of a modified early obstetric warning system (MEOWS) in managing maternal complications in the peripartum period: an ethnographic study

Objective To explore implementation of the modified early obstetric warning system (MEOWS) in practice to further understanding about the influence of contextual factors. Methods An ethnographic study using observations (>120 h), semi-structured interviews (n=45) and documentary review was performed in the maternity services in two UK hospitals over a 7-month period. Doctors, midwives and managers participated in the study and data were analysed thematically. Results For women admitted to hospital in the antenatal and postnatal period with an established risk of morbidity, the MEOWS enabled communication about vital signs from junior to senior midwives and obstetricians. The trigger prompts helped shape shared understandings of maternal complications. However, midwifery and obstetric staff questioned the added value of an extra chart in the postnatal period given the low incidence of maternal complications and the resulting increase in workload. In an effort to prioritise workload demands and respond to the immediate needs of both women and their babies, midwives exercised professional discretion regarding its use. However, discretionary use of MEOWS meant the loss of a potential universal safety net for detection of deterioration. Conclusions Despite a decade of use in acute settings, research into the effectiveness of early warning systems still yields conflicting results. Widespread policy support for the MEOWS is based on its intuitive appeal and no validated system for use in the maternity population currently exists. Our findings suggest that, while the MEOWS has value in structuring the surveillance of hospitalised women with an established risk of morbidity, the complexities of managing risk and safety within the maternity pathway, the associated opportunity costs of MEOWS and variation in implementation currently call into question its role for routine use.

Supporting patient safety: Examining communication within delivery suite teams through contrasting approaches to research observation

OBJECTIVE to explore the nature of intra- and interprofessional communication on delivery suites, with a particular focus on patient safety. DESIGN longitudinal study using contrasting forms of observation: ethnographic methods alongside the highly structured Interaction Process Analysis (IPA) framework. SETTING four contrasting delivery suites offering different models of care and serving different populations: two in the north of England and two in London. PARTICIPANTS the multidisciplinary delivery suite teams and visiting professionals from related areas. KEY FINDINGS the ethnographic observations and quantitative findings combine to highlight four principal areas relating to communication: communication underpinning collaboration; effects of workload pressures on communication practices; interprofessional communication; and the influence of architecture on communication. Contextual factors (e.g. case acuity, client throughput, model of care) underscore some inter site differences and attention is drawn to implications for safety. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE the use of complementary methods aided exploration of communication in the complex environment of the delivery suite. The findings reflect the complexity of communication patterns and the multiple influences on patterns and norms. Interprofessional tensions, workload pressures and the design of the environment can restrict communication, with implications for safety. As such, these findings have implications for policy in that safety solutions which focus efforts on standardising communication need to be located within wider strategies that also address structural and organisational networks and influences.

The role of patients and their relatives in ‘speaking up’ about their own safety – a qualitative study of acute illness

Poor recognition of and response to acute illness in hospitalized patients continues to cause significant harm despite the implementation of safety strategies such as early warning scores. Patients and their relatives may be able to contribute to their own safety by speaking up about changes in condition, but little is known about the factors that influence this. This study examined the experiences and views of patients and their relatives to determine the potential for involvement in promoting their own safety.

A methodological study to compare survey-based and observation-based evaluations of organisational and safety cultures and then compare both approaches with markers of the quality of care.

BACKGROUND Patient safety concerns have focused attention on organisational and safety cultures, in turn directing attention to the measurement of organisational and safety climates. OBJECTIVES First, to compare levels of agreement between survey- and observation-based measures of organisational and safety climates/cultures and to compare both measures with criterion-based audits of the quality of care, using evidence-based markers drawn from national care standards relating to six common clinical conditions. (This required development of an observation-based instrument.) Second, to examine whether observation-based evaluations could replace or augment survey measurements to mitigate concerns about declining response rates and increasing social desirability bias. Third, to examine mediating factors in safety and organisational climate scores. DESIGN The study had three strands: (A) a postal questionnaire survey to elicit staff perceptions of organisational and safety climates, using six prevalidated scales; (B) semistructured non-participant observation of clinical teams; and (C) a retrospective criterion-based audit carried out by non-clinical auditors to minimise hindsight bias. Standardised summary scores were created for each strand, and pairs of measurements were compared (strand A with strand B, strand A with strand C, and strand B with strand C) using Bland-Altman plots to evaluate agreement. Correlations were also examined. Multilevel modelling of Strand A scores explored mediating factors. SETTING AND PARTICIPANTS Eight emergency departments and eight maternity units in England, UK. INTERVENTIONS None. MAIN OUTCOME MEASURES Examination of feasibility, correlation and agreement. RESULTS Strand A: the overall response rate was 27.6%, whereas site-specific rates ranged from 9% to 47%. We identified more mediating factors than previous studies; variable response rates had little effect on the results. Organisational and safety climate scores were strongly correlated (r = 0.845) and exhibited good agreement [standard deviation (SD) differences 0.449; 14 (88%) within ± 0.5; one large difference]. Two commonly used scales had high levels of positive responses, suggesting positive climates or social desirability bias. Strand B: scoring on a four-point scale was feasible. Observational evaluation of teamwork culture was good but too limited for evaluating organisational culture. Strand C: a total of 359-399 cases were audited per condition. The results varied widely between different markers for the same condition, so selection matters. Each site performed well on some markers but not others, with few consistent patterns. Some national guidelines were contested. Comparisons: the comparison of safety climate (survey) and teamwork culture (observation) revealed a moderately low correlation (r = 0.316) and good agreement [SD differences 1.082; 7 (44%) within ±0.5; one large difference]. The comparison of safety climate (survey) and performance (audit) revealed lower correlation (r = 0.150, i.e. relationship not linear) but reasonably good agreement [SD differences 0.992; 9 (56%) within ± 0.5; two large differences]. Comparisons between performance (audit) and both organisational climate (survey) and teamwork culture (observation) showed negligible correlations (< 0.1) but moderately good agreement [SD differences 1.058 and 1.241; 6 (38%) and 7 (44%) within ± 0.5; each with two large differences (at different sites)]. Field notes illuminated large differences. CONCLUSIONS Climate scores from staff surveys are not unduly affected by survey response rates, but increasing use risks social desirability bias. Safety climate provides a partial indicator of performance, but qualitative data are needed to understand discrepant results. Safety climate (surveys) and, to a lesser degree, teamwork culture (observations) are better indicators of performance than organisational climate (surveys) or attempts to evaluate organisational culture from time-limited observations. Scoring unobtrusive, time-limited observations to evaluate teamwork culture is feasible, but the instrument developed for this study needs further testing. A refined observation-based measure would be useful to augment or replace surveys. FUNDING The National Institute for Health Research Health Technology Assessment programme.

The social practice of rescue: the safety implications of acute illness trajectories and patient categorisation in medical and maternity settings

Abstract The normative position in acute hospital care when a patient is seriously ill is to resuscitate and rescue. However, a number of UK and international reports have highlighted problems with the lack of timely recognition, treatment and referral of patients whose condition is deteriorating while being cared for on hospital wards. This article explores the social practice of rescue, and the structural and cultural influences that guide the categorisation and ordering of acutely ill patients in different hospital settings. We draw on Strauss et al.s notion of the patient trajectory and link this with the impact of categorisation practices, thus extending insights beyond those gained from emergency department triage to care management processes further downstream on the hospital ward. Using ethnographic data collected from medical wards and maternity care settings in two UK inner city hospitals, we explore how differences in population, cultural norms, categorisation work and trajectories of clinical deterioration interlink and influence patient safety. An analysis of the variation in findings between care settings and patient groups enables us to consider socio‐political influences and the specifics of how staff manage trade‐offs linked to the enactment of core values such as safety and equity in practice.

Working for patient safety: a qualitative study of women’s help-seeking during acute perinatal events

BackgroundWomen and their relatives can play an important role in early detection and help seeking for acute perinatal events. Recent UK reports indicate that patient-professional partnership in ‘working for safety’ can be difficult to achieve in practice, sometimes with catastrophic consequences. This research explored the experiences of women and relatives who had experienced early warning signs about their condition and sought help in escalating care.MethodsSecondary analysis of case study data which included qualitative interviews with 22 women purposively sampled on account of experiencing a step up in care and 4 of their relatives from two NHS Trusts in England during 2010. Analysis focused on the type of safety work participants engaged in, and the opportunities and challenges reported by women and family members when negotiating safety at home and in hospital.ResultsWomen and relatives took on a dual responsibility for self-diagnosis, self-care and seeking triage, whilst trying to avoid overburdening stretched services. Being informed, however, did not necessarily enable engagement from staff and services. The women’s narratives highlighted the work that they engaged in to build a case for clinical attention, the negotiations that took place with health care professionals and the strategies women and partners drew on (such as objective signs and symptoms, use of verbal insistence and repetition) to secure clinical help. For some women, the events left them with a lasting feeling that their concerns had been disregarded. Some described a sense of betrayal and loss of trust in an institution they believed had failed to care for them.ConclusionThe notion of ‘safety partnerships’ which suggests a sense of equality and reciprocity was not borne out by our data, especially with regards to the experiences of teenage women. To enable women and families to secure a rapid response in clinical emergencies, strategies need to move beyond the provision of patient information about warning signs. Effective partnerships for safety may be supported by system level change such as improved triage, continuity of care, self-referral pathways and staff training to address asymmetries of power that persist within the health system.

A narrative synthesis of factors that affect women speaking up about early warning signs and symptoms of pre-eclampsia and responses of healthcare staff

BackgroundOne of the challenges for treating pre-eclampsia and preventing further deterioration is determining how best to enable early detection. If women or their partners and families are able to raise early warnings about potential signs and symptoms of pre-eclampsia in pregnancy, birth and in the postnatal period, women may be able to receive earlier intervention to prevent severe pre-eclampsia from developing. The aim of this study was to improve understanding of factors affecting the ability of women to recognise symptoms and signs of pre-eclampsia/eclampsia and seek appropriate medical help and factors affecting health care professionals’ responses to women and their families who ‘speak up’ about early warning signs and symptoms.MethodsA narrative synthesis was conducted of evidence relevant to address the research question. The following electronic data bases were searched for qualitative studies which met inclusion criteria from January 1980 to April 2016; Medline, CINAHL, HMIC, PsycINFO, Embase, BNI, ASSIA, Scopus, Maternity and Infant Care, Web of Science, Google Scholar, Cochrane, JBI and IBSS with the support of an Information Service Consultant.ResultsFollowing thematic analysis, three themes were identified; 1: Women’s understanding and knowledge of pre-eclampsia/eclampsia; 2: Factors affecting help seeking behaviour from perspectives of women and their families’; 3: Factors affecting staff response. There was widespread lack of knowledge and understanding of signs and symptoms of pre-eclampsia/eclampsia among women and their families, with some women not exhibiting signs and symptoms of pre-eclampsia or unable to distinguish them from ‘normal’ pregnancy changes.ConclusionsWomen and their families not only need to be made aware of signs and symptoms of pre-eclampsia/eclampsia but also require information on the most effective ways to seek urgent medical assessment and care. Some women did not experience prodromal signs and symptoms, which raises concerns about how women and families can detect early onset, and is an issue which needs further exploration. There is very limited research exploring clinical staff response to women who raise concerns about their health when experiencing symptoms and signs of pre-eclampsia/eclampsia with further research needed if safety and quality of care are to be improved.

Employing the arts for knowledge production and translation: Visualizing new possibilities for women speaking up about safety concerns in maternity

This project used animated film to translate research findings into accessible health information aimed at enabling women to speak up and secure professional help for serious safety concerns during pregnancy and after birth. We tested as proof of concept our use of the arts both as product (knowledge production) and process (enabling involvement).
