ABSTRACT

OBJECTIVES: In 2022, England embarked on an ambitious reorganisation to produce an integrated health and care system, intended also to maximise population health. The newly created integrated care systems (ICSs) aim to improve quality of care, by achieving the best outcomes for individuals and populations through the provision of evidence-based services. An emerging approach for managing quality in organisations is the Quality Management System (QMS) framework. Using the framework, this study assessed how ICSs are managing and improving quality. METHODS: Four ICSs were purposively sampled, with the data collected between November 2021 and May 2022. Semi-structured interviews with system leaders (n=60) from health and social care, public health and local representatives were held. We also observed key ICS meetings and reviewed relevant documents. A thematic framework approach based on the QMS framework was used to analyse the data. RESULTS: The ICSs placed an emphasis on population health, reducing inequity and improving access. This represents a shift in focus from the traditional clinical approach to quality. There were tensions between quality assurance and improvement, with concerns that a narrow focus on assurance would impede ICSs from addressing broader quality issues, such as tackling inequalities and unwarranted variation in care and outcomes. Partnerships, a key enabler for integration, was seen as integral to achieving improvements in quality. Overall, the ICSs expressed concerns that any progress made in quality development and in improving population health would be tempered by unprecedented system pressures. CONCLUSION: It is unclear whether ICSs can achieve their ambition. As they move away from an assurance-dominated model of quality to one that emphasises openness, learning and improvement, they must simultaneously build the digital infrastructure, staff expertise and culture to support such a shift.

ABSTRACT

The Special Measures and Challenged Provider (SMCP) Regime introduced for struggling healthcare organisations in England represents a subtle shift to the scope of external regulation from performance oversight to include supporting internal service improvement. External regulation alone has a had a mixed impact on the quality of care and Vindrola-Padros and colleagues' study highlights that externally driven improvement initiatives may also struggle to succeed in turning around performance. Principally, this is due to a failure in acknowledgment that poor performance results from a myriad of external and internal factors which coalesce to impede organisational performance. A struggling organisation may be indicative of wider issues in the local health and care system. Whole systems approaches to improvement with collaboration across providers and the effective use of data may support struggling organisations but their role maybe tempered with the increased centralisation of the delivery of improvement regimes such as SMCP.

ABSTRACT

Poor-quality medicines pose a significant challenge for health systems in low- to middle-income countries (LMICs),with recent deaths in multiple countries following ingestion of substandard cough syrups emphasising the need for quality-assurance of medicines in our increasingly interconnected global markets. Research also suggests that the source (country of manufacture) and type of medicine (generic/brand) are perceived to be associated with medicine quality. This study explores perceptions of medicines quality among national stakeholders of a medicines quality assurance system (MQAS) in sub-Saharan Africa. Through semi-structured interviews (n = 29) with managers from organisations responsible for the MQAS, public-sector doctors and nurses, and regulated private-sector pharmacists in three urban centres in Senegal in 2013. A thematic approach to analysis was undertaken with themes organised under three main categories, the source of drugs, the type of medicine, and medicines storage. A key emerging theme was the perception of the inferior quality of generic medicines, especially those produced in Asia and Africa, as they were lower in cost and thus believed to be less effective in alleviating symptoms than their brand versions. Medicines in Senegal's less regulated (informal) street markets were also thought to be of poor-quality as they were not subjected to national regulatory processes or stored appropriately, resulting in exposure to direct sunlight and high temperatures. In contrast, the interviewees expressed confidence in medicines quality within the regulated sectors (public and private retail pharmacies) attributed to stringent national medicines regulation, secure medicines supply chains and adequate technical capacity to survey and analyse for medicines quality. Also, the views expressed typically described a medicine's quality in terms of its effectiveness in alleviating the symptoms of ill health (efficacy of a medicine).These perceptions may have implications for developing national medicines policy, the procurement and supply of affordable medicines and consumers' decision-making when purchasing medicines. Indeed, a proclivity for supplying and purchasing more expensive brand medicines may act as a barrier to accessing essential medicines.

ABSTRACT

OBJECTIVES: This scoping review aimed to establish the approaches employed to improving patient safety in integrated care for community-dwelling adults with long-term conditions. DESIGN: Scoping review. SETTING: All care settings. SEARCH STRATEGY: Systematic searches of seven academic and grey literature databases for studies published between 2000 and 2021. At the full-text review stage both the first and second reviewer (SW) independently assessed full texts against the eligibility criteria and any discrepancies were discussed. RESULTS: Overall, 24 studies were included in the review. Two key priorities for safety across care boundaries for adults with long-term conditions were falls and medication safety. Approaches for these priorities were implemented at different levels of an integrated care system. At the micro-level, approaches involved care primarily in the home setting provided by multi-disciplinary teams. At the meso-level, the focus was on planning and designing approaches at the managerial/organisational level to deliver multi-disciplinary care. At the macro-level, system-wide approaches included integrated care records, training and education and the development of care pathways involving multiple organisations. Across the included studies, evaluation of these approaches was undertaken using a wide range of process and outcome measures to capture patient harm and contributory factors associated with falls and medication safety. CONCLUSIONS: For integrated care initiatives to fulfil their promise of improving care for adults with long-term conditions, approaches to improve patient safety need to be instituted across the system, at all levels to support the structural and relational aspects of integrated care as well as specific risk-related safety improvements.

ABSTRACT

OBJECTIVE: A new patient safety policy, 'Learning from Deaths' (LfD), was implemented in 2017 in National Health Service (NHS) organisations in England. This study examined how contextual factors influenced the implementation of LfD policy and the ability of the programme to achieve its goals. METHODS: Semi-structured interviews were undertaken with key policymakers involved in the development of the policy, along with interviews with managers and senior clinicians in five NHS organisations responsible for implementing the policy at the local level. We also undertook non-participant observation of relevant meetings and documentary reviews of key organisation procedures and policies pertaining to LfD. RESULTS: The study findings suggest several factors that hinder or support patient safety policy implementation at a local level. These include: (a) an organisation's capacity and capability to support data collation, analysis and synthesis, (b) the dissemination of the resulting information, (c) the learning culture and hence perceptions of the purpose of LfD within an organisation, and (d) the extent of engagement in cross-organisational approaches to learning. CONCLUSIONS: Extra and intra-organisational contextual factors influence all stages of the policy implementation process from preparation and tracking to implementation support and review affecting its chances of success or failure. Successful adoption of a national patient safety policy within health care organisations can be informed by taking into consideration those factors.

ABSTRACT

In an attempt to support care integration that promotes joined up service provision and patient-centred care across care boundaries, local health and social care organisations have embarked on several initiatives and approaches. A key component of service integration is the co-location of different professional groups. In this study, we consider the extent to which co-location is an enabler for service integration by examining multi-professional community care teams. The study presents findings from a qualitative evaluation of integrated care initiatives in a borough of East London, England, undertaken between 2017 and 2018. The evaluation employed a participatory approach, the Researcher-in-Residence model. Participant observation (n = 80 hr) and both semi-structured individual (n = 16) and group interviews (six groups, n = 17 participants) were carried out. Thematic analysis of the data was undertaken. The findings show that co-location can be an effective enabler for service integration providing a basis for joint working, fostering improved communication and information sharing if conditions such as shared information systems and professional cultures (shared beliefs and values) are met. Organisations must consider the potential barriers to service integration such as differing professional identity, limited understanding of roles and responsibilities and a lack of continuity in personnel. Co-location remains an important facet in the development of multi-professional teams and local service integration arrangements, but as yet, has not been widely acknowledged as a priority in care practice. Organisations that are committed to greying care boundaries and providing joined up patient care must ensure that sufficient focus is provided at the service delivery level and not assume that decades of silo working in health and social care and strong professional cultures will be resolved by co-location.

ABSTRACT

OBJECTIVE: In recent years there has been a proliferation of patient safety policies in the United Kingdom triggered by well publicized failures in health care. The Learning from Deaths (LfD) policy was implemented in response to failures at Southern Health National Health Service (NHS) Foundation Trust. This study aims to develop a narrative to enable the understanding of the key drivers involved in its evolution and implications for future national patient safety policy development. METHODS: A qualitative study was undertaken using documentary analysis and semi-structured interviews (n = 12) with policymakers from organizations involved in the design, implementation and assurance of LfD at a system level. Kingdon's Multiple Streams Approach was used to frame the policymaking process. RESULTS: The publication of the Southern Health independent review and subsequent highlighting by the Care Quality Commission of a fragmented approach to learning from deaths across the NHS opened a 'policy window.' Under the influence of the families affected by patient safety failures and the then Secretary of State, acting as 'policy entrepreneurs,' recently developed methods for mortality review were combined with mechanisms to enhance transparency and governance. This rapidly created a framework designed to ensure NHS organizations identified remedial safety problems and could be accountable for addressing them. CONCLUSIONS: The development of LfD exhibits several common features with other patient safety policies in the NHS. It was triggered by a crisis and the need for a prompt political response and attempts to address a range of concerns related to safety. In common with other safety policies, LfD contains inherent tensions related to its primary purpose, which may hinder its impact. In the absence of formal evaluations of these policies, deeper understanding of the policymaking process offers the possibility of identifying potential barriers to goal achievement.

ABSTRACT

Integrated care has been proposed as an organising principle to address the challenges of the rising demand for care services and limited resources. There is limited understanding of the role of learning in integrated care systems. Organisational Learning (OL) theory in the guise of 'Learning Practice' can offer a lens to study service integration and reflect on some of the challenges faced by multi-professional teams in developing a learning culture. The study presents findings from two qualitative evaluations of integrated care initiatives in three East London boroughs, England, undertaken between 2017 and 2018. The evaluations employed a participatory approach, the researcher-in-residence model, to coproduce findings with frontline staff working in multi-professional teams in community care. Thematic analysis was undertaken using an adapted version of the 'Learning Practice' framework. The majority of learning in the teams was single loop i.e. learning was mainly reactive to issues that arise. Developing a learning culture in the three boroughs was hindered by the differences in the professional and organisational cultures of health and social care and challenges in developing effective structures for learning. Individual organisational priorities and pressures inhibited both the embedding of learning and effective integration of care services at the frontline. Currently, learning is not inherent in integrated care planning. The adoption of the principles of OL optimising learning opportunities, support of innovation, managed risk taking and capitalising on the will of staff to work in multidisciplinary teams might positively contribute to the development of service integration.

ABSTRACT

BACKGROUND: Buurtzorg, a model of community nursing conceived in the Netherlands, is widely cited as a promising and evidence-based approach to improving the delivery of integrated nursing and social care in community settings. The model is characterised by high levels of patient and staff satisfaction, professional autonomy exercised through self-managing nursing teams, client empowerment and holistic, patient centred care. This study aimed to examine the extent to which some of the principles of the Buurtzorg model could be adapted for community nursing in the United Kingdom. METHODS: A community nursing model based on the Buurtzorg approach was piloted from June 2017-August 2018 with a team of nurses co-located in a single general practice in the Borough of Tower Hamlets, East London, UK. The initiative was evaluated using a participatory methodology known as the Researcher-in-Residence model. Qualitative data were collected using participant observation of meetings and semi-structured interviews with nurse team members, senior managers, patients/carers and other local stakeholders such as General Practitioners (GP) and social workers. A thematic framework analysis of the data was carried out. RESULTS: Implementation of a community nursing model based on the Buurtzorg approach in East London had mixed success when assessed against its key principles. Patient experience of the service was positive because of the better access, improved continuity of care and longer appointment times in comparison with traditional community nursing provision. The model also provided important learning for developing service integration in community care, in particular, how to form effective collaborations across the care system with other health and social care professionals. However, some of the core features of the Buurtzorg model were difficult to put into practice in the National Health Service (NHS) because of significant cultural and regulatory differences between The Netherlands and the UK, especially the nurses' ability to exercise professional autonomy. CONCLUSIONS: Whilst many of the principles of the Buurtzorg model are applicable and transferable to the UK, in particular promoting independence among patients, improving patient experience and empowering frontline staff, the successful embedding of these aims as normalised ways of working will require a significant cultural shift at all levels of the NHS.

ABSTRACT

BACKGROUND: Patient and public involvement (PPI) continues to develop as a central policy agenda in health care. The patient voice is seen as relevant, informative and can drive service improvement. However, critical exploration of PPI's role within monitoring and informing medical performance processes remains limited. OBJECTIVE: To explore and evaluate the contribution of PPI in medical performance processes to understand its extent, purpose and process. SEARCH STRATEGY: The electronic databases PubMed, PsycINFO and Google Scholar were systematically searched for studies published between 2004 and 2018. INCLUSION CRITERIA: Studies involving doctors and patients and all forms of patient input (eg, patient feedback) associated with medical performance were included. DATA EXTRACTION AND SYNTHESIS: Using an inductive approach to analysis and synthesis, a coding framework was developed which was structured around three key themes: issues that shape PPI in medical performance processes; mechanisms for PPI; and the potential impacts of PPI on medical performance processes. MAIN RESULTS: From 4772 studies, 48 articles (from 10 countries) met the inclusion criteria. Findings suggest that the extent of PPI in medical performance processes globally is highly variable and is primarily achieved through providing patient feedback or complaints. The emerging evidence suggests that PPI can encourage improvements in the quality of patient care, enable professional development and promote professionalism. DISCUSSION AND CONCLUSIONS: Developing more innovative methods of PPI beyond patient feedback and complaints may help revolutionize the practice of PPI into a collaborative partnership, facilitating the development of proactive relationships between the medical profession, patients and the public.

ABSTRACT

BACKGROUND: Patient feedback is considered integral to quality improvement and professional development. However, while popular across the educational continuum, evidence to support its efficacy in facilitating positive behaviour change in a postgraduate setting remains unclear. This review therefore aims to explore the evidence that supports, or refutes, the impact of patient feedback on the medical performance of qualified doctors. METHODS: Electronic databases PubMed, EMBASE, Medline and PsycINFO were systematically searched for studies assessing the impact of patient feedback on medical performance published in the English language between 2006-2016. Impact was defined as a measured change in behaviour using Barr's (2000) adaptation of Kirkpatrick's four level evaluation model. Papers were quality appraised, thematically analysed and synthesised using a narrative approach. RESULTS: From 1,269 initial studies, 20 articles were included (qualitative (n=8); observational (n=6); systematic review (n=3); mixed methodology (n=1); randomised control trial (n=1); and longitudinal (n=1) design). One article identified change at an organisational level (Kirkpatrick level 4); six reported a measured change in behaviour (Kirkpatrick level 3b); 12 identified self-reported change or intention to change (Kirkpatrick level 3a), and one identified knowledge or skill acquisition (Kirkpatrick level 2). No study identified a change at the highest level, an improvement in the health and wellbeing of patients. The main factors found to influence the impact of patient feedback were: specificity; perceived credibility; congruence with physician self-perceptions and performance expectations; presence of facilitation and reflection; and inclusion of narrative comments. The quality of feedback facilitation and local professional cultures also appeared integral to positive behaviour change. CONCLUSION: Patient feedback can have an impact on medical performance. However, actionable change is influenced by several contextual factors and cannot simply be guaranteed. Patient feedback is likely to be more influential if it is specific, collected through credible methods and contains narrative information. Data obtained should be fed back in a way that facilitates reflective discussion and encourages the formulation of actionable behaviour change. A supportive cultural understanding of patient feedback and its intended purpose is also essential for its effective use.

ABSTRACT

OBJECTIVES: This study explores the barriers and facilitators that impact on the motivation of practitioners to participate in a quality improvement collaborative. DESIGN: A qualitative and formative evaluation using a participatory approach, the researcher-in-residence model which embraces the concept of 'coproducing' knowledge between researchers and practitioners using a range of research methods such as participant observation, interviews and documentary analysis. The design, creation and application of newly generated evidence are facilitated by the researcher through negotiation and compromise with team members. PARTICIPANTS: Senior and middle managers, doctors and nurses. SETTING: Two hospitals in Southeast England participating in a Patient Safety Improvement Collaborative and the facilitator (host) of the collaborative, based in Central London. RESULTS: The evaluation has revealed facilitators and barriers to motivation categorised under two main themes: (1) inherent motivation and (2) factors that influence motivation, interorganisational and intraorganisational features as well as external factors. Facilitators included collaborative 'champions,' individuals who drove the quality improvement agenda at a local level, raising awareness and inspiring colleagues. The collaborative itself acted as a facilitator, promoting shared learning as well as building motivation for participation. A key barrier was the lack of board engagement in the participating National Health Service organisations which may have affected motivation among front-line staff. CONCLUSIONS: Collaboratives maybe an important way of engaging practitioners in quality improvement initiatives. This study highlights that despite a challenging healthcare environment in the UK, there remains motivation among individuals to participate in quality improvement programmes as they recognise that improvement approaches may facilitate positive change in local clinical processes and systems. Collaboratives can harness this individual motivation to facilitate spread and adoption of improvement methodology and build engagement across their membership.

ABSTRACT

BACKGROUND: Assessing the quality of medicines in low-middle income countries (LMICs) relies primarily on human inspection and screening technologies, where available. Field studies and surveys have frequently utilized screening tests to analyse medicines sampled at the point of care, such as health care facilities and medicine outlets, to provide a snap shot of medicine quality in a specific geographical area. This review presents an overview of the screening tests typically employed in surveys to assess anti-malarial medicine quality, summarizes the analytical methods used, how findings have been reported and proposes a reporting template for future studies. METHODS: A systematic search of the peer-reviewed and grey literature available in the public domain (including national and multi-national medicine quality surveys) covering the period 1990-2016 was undertaken. Studies were included if they had used screening techniques to assess the quality of anti-malarial medicines. As no standardized set of guidelines for the methodology and reporting of medicine quality surveys exist, the included studies were assessed for their standard against a newly proposed list of criteria. RESULTS: The titles and abstracts of 4621 records were screened and only 39 were found to meet the eligibility criteria. These 39 studies utilized visual inspection, disintegration, colorimetry and Thin Layer Chromatography (TLC) either as components of the Global Pharma Health Fund (GPHF) MiniLab® or as individual tests. Overall, 30/39 studies reported employing confirmatory testing described in international pharmacopeia to verify the quality of anti-malarials post assessment by a screening test. The authors assigned scores for the 23 criteria for the standard of reporting of each study. CONCLUSIONS: There is considerable heterogeneity in study design and inconsistency in reporting of field surveys of medicine quality. A lack of standardization in the design and reporting of studies of medicine quality increases the risk of bias and error, impacting on the generalizability and reliability of study results. The criteria proposed for reporting on the standard of studies in this review can be used in conjunction with existing medicine quality survey guidelines as a checklist for designing and reporting findings of studies. The review protocol has been registered with PROSPERO (CRD42015026782).

ABSTRACT

This meeting report presents the key findings and discussion points of a 1-day meeting entitled 'Fake anti-malarials: start with the facts' held on 28th May 2015, in Geneva, Switzerland, to disseminate the findings of the artemisinin combination therapy consortium's drug quality programme. The teams purchased over 10,000 samples, using representative sampling approaches, from six malaria endemic countries: Equatorial Guinea (Bioko Island), Cambodia, Ghana, Nigeria, Rwanda and Tanzania. Laboratory analyses of these samples showed that falsified anti-malarials (<8 %) were found in just two of the countries, whilst substandard artemisinin-based combinations were present in all six countries and, artemisinin-based monotherapy tablets are still available in some places despite the fact that the WHO has urged regulatory authorities in malaria-endemic countries to take measures to halt the production and marketing of these oral monotherapies since 2007. This report summarizes the presentations that reviewed the public health impact of falsified and substandard drugs, sampling strategies, techniques for drug quality analysis, approaches to strengthen health systems capacity for the surveillance of drug quality, and the ensuing discussion points from the dissemination meeting.

ABSTRACT

Little is known about the quality of antibiotics despite being in high demand globally. Thirty five samples (27 brands) of the antibiotics amoxicillin (N = 20; 16 brands) and co-trimoxazole (N = 15; 11 brands), manufactured in six countries (China, Ghana, India, Ireland, Nigeria, and United Kingdom), were purchased in Ghana, Nigeria, and the United Kingdom. Their quality was assessed using German Pharma Health Fund (GPHF) MiniLab® as the screening tool-two capsules of amoxicillin (10%) and two tablets of co-trimoxazole (20%) failed the thin-layer chromatography (TLC) test. Definitive drug quality was measured using high-performance liquid chromatography-photodiode array detection (HPLC-PDA) for content of the stated active pharmaceutical ingredients (APIs) and bioavailability was determined with in vitro dissolution testing. All the samples of amoxicillin complied with U.S. Pharmacopeia (USP) tolerance limits, but 60% tablets of co-trimoxazole (purchased in Ghana and Nigeria) did not. There was disparity in the results obtained for co-trimoxazole and amoxicillin samples using the MiniLab® TLC tests. This highlights the need to invest in techniques such as HPLC-PDA and dissolution testing alongside the screening tests for assessing drug quality.

ABSTRACT

Good-quality antimalarials are crucial for the effective treatment and control of malaria. A total of 7,740 individual and packaged tablets, ampoules, and syrups were obtained from 60 randomly selected public (N = 35) and private outlets (N = 25) in Afghanistan. Of these, 134 samples were screened using the Global Pharma Health Fund (GPHF) MiniLab® in Kabul with 33/126 (26%) samples failing the MiniLab® disintegration test. The quality of a subsample (N = 37) of cholorquine, quinine, and sulfadoxine/pyrimethamine tablets was assessed by in vitro dissolution testing following U.S. Pharmacopeia (USP) monographs at a bioanalytical laboratory in London, United Kingdom. Overall, 12/32 (32%) samples of sulfadoxine/pyrimethamine and quinine were found not to comply with the USP tolerance limits. Substandard antimalarials were available in Afghanistan demonstrating that continuous monitoring of drug quality is warranted. However, in Afghanistan as in many low-income countries, capacity to determine and monitor drug quality using methods such as dissolution testing needs to be established to empower national authorities to take appropriate action in setting up legislation and regulation.

ABSTRACT

BACKGROUND: Increasing access to and targeting of artemisinin-based combination therapy (ACT) is a key component of malaria control programmes. To maximize efficacy of ACT and ensure adequate treatment outcomes, patient and caregiver adherence to treatment guidelines is essential. This review summarizes the current evidence base on ACT adherence, including definitions, measurement methods, and associated factors. METHODS: A systematic search of the published literature was undertaken in November 2012 and updated in April 2013. Bibliographies of manuscripts were also searched and additional references identified. Studies were included if they involved at least one form of ACT and reported an adherence measurement. RESULTS: The search yielded 1,412 records, 37 of which were found to measure adherence to ACT. Methods to measure adherence focused on self-report, pill counts and bioassays with varying definitions for adherence. Most studies only reported whether medication regimens were completed, but did not assess how the treatment was taken by the patient (i.e. timing, frequency and dose). Adherence data were available for four different ACT formulations: artemether-lumefantrine (AL) (range 39-100%), amodiaquine plus artesunate (AQ + AS) (range 48-94%), artesunate plus sulphadoxine-pyrimethamine (AS + SP) (range 39-75%) and artesunate plus mefloquine (AS + MQ) (range 77-95%). Association between demographic factors, such as age, gender, education and socio-economic status and adherence to ACT regimens was not consistent. Some evidence of positive association between adherence and patient age, caregiver education levels, drug preferences, health worker instructions, patient/caregiver knowledge and drug packaging were also observed. CONCLUSIONS: This review highlights the weak evidence base on ACT adherence. Results suggest that ACT adherence levels varied substantially between study populations, but comparison between studies was challenging due to differences in study design, definitions, and methods used to measure adherence. Standardising methodologies for both self-report and bioassays used for evaluating adherence of different formulations across diverse contexts would improve the evidence base on ACT adherence and effectiveness; namely, specific and measurable definitions for adherence are needed for both methodologies. Additionally, further studies of the individual factors and barriers associated with non-adherence to ACT are needed in order to make informed policy choices and to improve the delivery of effective malaria treatment.
