Overview

I am an Academic General Practitioner, with a commitment to research on patient centred care that is relevant for decision making in clinical practice and health policy. I led the Health Services & Policy Research Group at the University of Exeter Medical School (2013-2021) and was the lead for Education and Training at the Exeter Collaboration for Academic Primary Care (APEx), NIHR School for Primary Care Research. I am presnetly Honorary Professor at the University, with main appointments as Professor of Medicine at the National University of Singapore, and Head of the Department of Family Medicine and Director of the Centre for Research in Health Systems Performance (CRiHSP) at the National University Health System, Singapore.

My research interests focus on the use of patient reports on their own health for decision making in clinical practice and health policy, and the improvement of processes of care (quality and safety), with a particular interest in patients with multiple conditions (multimorbidity). I have participated in over 50 research projects and have authored over 200 publications, including papers, books and book chapters, editorials, letters, and scientific communications and provided expert policy advice to the World Health Organization, Organization for the Economic Cooperation and Development, and NHS England, among others. I serve as Field Chief Editor for Frontiers in Health Services and Chairman of World organisation of Family Doctors (WONCA) Working Party in Quality & Safety and was elected President of the International Society for Quality of Life Research (2017-2019).

Since completing my training as a General Practitioner I have maintained active clinical practice in different countries and in a variety of environments, including developing countries for very brief periods. I am also devoted to postgraduate teaching, particularly in areas where research meets clinical practice (Applied Health Services Research, Clinical Epidemiology and Evidence Based Practice).

Broad Research Specialisms

My main areas of expertise are in patient centred care, with a particular focus on the use of measures of Patient Reported Outcomes and Experiences (development, adaptation, application, interpretation and clinical applications of PROMs, qualitative methods for content generation, psychometrics and quantitative analyses (classical test theory and Item Response Theory Models), and appraisal of instruments), multi- and co-morbidity, and quality and safety in Primary Care.

Qualifications

• BMBS (University of Barcelona, Spain)
• General Practitioner (Department of Education, Spain)
• MPH (Pompeu Fabra University, Spain)
• PhD (Pompeu Fabra University, Spain)

Career

After combining my PhD (IMIM-Hospital del Mar and Pompeu Fabra University) and my training as a General Practitioner in Barcelona, Spain, I started my post-doctoral research at the Department of Health Policy and Management, Johns Hopkins Bloomberg School of Public Health under the supervision of the late Prof. Barbara Starfield. I then joined the National Primary Care Research and Development Centre, University of Manchester led by Prof. Martin Roland, and in 2010 arrived at the Nuffield Department of Primary Care Health Sciences at the University of Oxford to set up and lead the Health Services and Policy Research Group. In September 2013, I was appointed Chair in Health Services and Policy Research at the University of Exeter Medical School. In January 2022 I took up the role of Head of Department of Family Medicine at the National University Health System in Singapore.

Hjollund NHI, Valderas JM, Kyte D, Calvert MJ (In Press). Health Data Processes: a Framework for Analyzing and Discussing Efficient Use and Reuse of Health Data with a Focus on Patient-Reported Outcome Measures (Preprint).

. UNSTRUCTURED
. The collection and use of patient health data are central to any kind of activity in the health care system. These data may be produced during routine clinical processes or obtained directly from the patient using patient-reported outcome (PRO) measures. Although efficiency and other reasons justify data availability for a range of potentially relevant uses, these data are nearly always collected for a single specific purpose. The health care literature reflects this narrow scope, and there is limited literature on the joint use of health data for daily clinical use, clinical research, surveillance, and administrative purposes. The aim of this paper is to provide a framework for discussing the efficient use of health data with a specific focus on the role of PRO measures. PRO data may be used at an individual patient level to inform patient care or shared decision making and to tailor care to individual needs or group-level needs as a complement to health record data, such as that on mortality and readmission, in order to inform service delivery and measure the real-world effectiveness of treatment. PRO measures may be used either for their own sake, to provide valuable information from the patient perspective, or as a proxy for clinical data that would otherwise not be feasible to collect. We introduce a framework to analyze any health care activity that involves health data. The framework consists of four data processes (patient identification, data collection, data aggregation and data use), further structured into two dichotomous dimensions in each data process (level: group vs patient; timeframe: ad hoc vs systematic). This framework is used to analyze various health activities with respect to joint use of data, considering the technical, legal, organizational, and logistical challenges that characterize each data process. Finally, we propose a model for joint use of health data with data collected during follow-up as a base. Demands for health data will continue to increase, which will further add to the need for the concerted use and reuse of PRO data for parallel purposes. Repeated and uncoordinated PRO data collection for the same patient for different purposes results in misuse of resources for the patient and the health care system as well as reduced response rates owing to questionnaire fatigue. PRO data can be routinely collected both at the hospital (from inpatients as well as outpatients) and outside of hospital settings; in primary or social care settings; or in the patient’s home, provided the health informatics infrastructure is in place. In the future, clinical settings are likely to be a prominent source of PRO data; however, we are also likely to see increased remote collection of PRO data by patients in their own home (telePRO). Data collection for research and quality surveillance will have to adapt to this circumstance and adopt complementary data capture methods that take advantage of the utility of PRO data collected during daily clinical practice. The European Union’s regulation with respect to the protection of personal data—General Data Protection Regulation—imposes severe restrictions on the use of health data for parallel purposes, and steps should be taken to alleviate the consequences while still protecting personal data against misuse.

. BACKGROUND
. Patient-reported measure (PRM) questionnaires were originally used in research to measure outcomes of intervention studies. They have now evolved into a diverse family of tools measuring a range of constructs including quality of life and experiences of care. Current health and social care policy increasingly advocates their use for embedding the patient voice into service redesign through new models of care such as person-centered coordinated care (P3C). If chosen carefully and used efficiently, these tools can help improve care delivery through a variety of novel ways, including system-level feedback for health care management and commissioning. Support and guidance on how to use these tools would be critical to achieve these goals.
.
.
. OBJECTIVE
. The objective of this study was to develop evidence-based guidance and support for the use of P3C-PRMs in health and social care policy through identification of PRMs that can be used to enhance the development of P3C, mapping P3C-PRMs against an existing model of domains of P3C, and integration and organization of the information in a user-friendly Web-based database.
.
.
. METHODS
. A pragmatic approach was used for the systematic identification of candidate P3C-PRMs, which aimed at balancing comprehensiveness and feasibility. This utilized a number of resources, including existing compendiums, peer-reviewed and gray literature (using a flexible search strategy), and stakeholder engagement (which included guidance for relevant clinical areas). A subset of those candidate measures (meeting prespecified eligibility criteria) was then mapped against a theoretical model of P3C, facilitating classification of the construct being measured and the subsequent generation of shortlists for generic P3C measures, specific aspects of P3C (eg, communication or decision making), and condition-specific measures (eg, diabetes, cancer) in priority areas, as highlighted by stakeholders.
.
.
. RESULTS
. In total, 328 P3C-PRMs were identified, which were used to populate a freely available Web-based database. of these, 63 P3C-PRMs met the eligibility criteria for shortlisting and were classified according to their measurement constructs and mapped against the theoretical P3C model. We identified tools with the best coverage of P3C, thereby providing evidence of their content validity as outcome measures for new models of care. Transitions and medications were 2 areas currently poorly covered by existing measures. All the information is currently available at a user-friendly web-based portal (p3c.org.uk), which includes all relevant information on each measure, such as the constructs targeted and links to relevant literature, in addition to shortlists according to relevant constructs.
.
.
. CONCLUSIONS
. A detailed compendium of P3C-PRMs has been developed using a pragmatic systematic approach supported by stakeholder engagement. Our user-friendly suite of tools is designed to act as a portal to the world of PRMs for P3C, and have utility for a broad audience, including (but not limited to) health care commissioners, managers, and researchers.

Piloting the SinergyAPS theory-based online intervention centred around the systematic patient feedback for improving patient safety in Primary Care: a mixed-methods feasibility study (Preprint).

. BACKGROUND
. Developing new strategies to support the provision of safer primary care (PC) is a major priority both internationally and in Spain, where around 3 million adverse events occur each year in the PC setting.
.
.
. OBJECTIVE
. The primary aims of this mixed-methods feasibility study were to examine the feasibility and to explore the acceptability and perceived utility of the SinergiAPS intervention, a novel low-cost and scalable theory-based online intervention to improve patient safety in PC centres, based on the use of patient feedback. The secondary aim was to examine the potential impact of the intervention to improve patient safety culture and avoidable hospitalizations in PC centres.
.
.
. METHODS
. We conducted a three-month, one-arm, feasibility trial in ten PC centres in Spain. Centres were fed back information regarding patients' experiences of safety (collected through PREOS-PC questionnaire) and were instructed to plan safety improvement actions based on it. We measured recruitment and follow-up rates, and intervention uptake (number of centres registering improvement plans). We explored the impact of the intervention on patient safety culture (MOSPSC questionnaire), and avoidable hospital admissions rate. We conducted semi-structured interviews with nine professionals to explore the acceptability and perceived utility of the intervention.
.
.
. RESULTS
. of 256 professionals invited, 120 (47%) accepted to participate and 97 completed baseline and post-intervention measures. of 780 patients invited, 585 (77%) completed the PREOS-PC questionnaire. Five centres designed 27 improvement actions. Most of the actions addressed treatment-related safety problems and consisted in the provision of training to PC providers. Compared to baseline, post-intervention MOSPSC scores were significantly higher (indicating a higher level of culture) for the safety culture synthetic index (3.36/5 at baseline vs. 3.44/5 at post-intervention (2% increase); p=0.01). No differences (p=0.11) were observed in avoidable admissions rate before (median (IQR)=0.78 (0.7 to 0.9) vs. after the intervention (0.45 (0.33 to 0.83)). The interviews revealed that the intervention was perceived as a novel strategy that could produce long-term safety improvements by raising their awareness and improving their technical knowledge about patient safety.
.
.
. CONCLUSIONS
. The proposed intervention is feasible to deliver and perceived as acceptable and useful by PC professionals if the barriers identified are addressed. The effectiveness of the refined intervention will be assessed in a trial involving 59 centres.

BMJ Open, 11(9), e046712-e046712.

Total hip arthroplasty (THA) surgery for elderly people with multimorbidity increases the risk of serious health hazards including mortality. Whether such background morbidity reduces the clinical benefit is less clear.ObjectiveTo evaluate how pre-existing health status, using multiple approaches, influences risks of, and quality of life benefits from, THA.SettingLongitudinal record linkage study of a UK sample linking their primary care to their secondary care records.ParticipantsA total of 6682 patients were included, based on the recording of the diagnosis of hip osteoarthritis in a national primary care register and the recording of the receipt of THA in a national secondary care register.Data were extracted from the primary care register on background health and morbidity status using five different constructs: Charlson Comorbidity Index, Electronic Frailty Index (eFI) and counts of comorbidity disorders (from list of 17), prescribed medications and number of primary care visits prior to recording of THA.Outcome measures(1) Postoperative complications and mortality; (2) postoperative hip pain and function using the Oxford Hip Score (OHS) and health-related quality of life using the EuroQoL (EQ)-5D score.ResultsPerioperative complication rate was 3.2% and mortality was 0.9%, both increased with worse preoperative health status although this relationship varied depending on the morbidity construct: the eFI showing the strongest relationship but number of visits having no predictive value. By contrast, the benefits were not reduced in those with worse preoperative health, and improvement in both OHS and EQ-5D was observed in all the morbidity categories.ConclusionsIndependent of preoperative morbidity, THA leads to similar substantial improvements in quality of life. These are offset by an increase in medical complications in some subgroups of patients with high morbidity, depending on the definition used. For most elderly people, their other health disorders should not be a barrier for THA.

UNLABELLED: Policy Points the 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. While there is a large amount of literature on the economic aspects of delivering primary care services, there is a need for more comprehensive overviews of this evidence. In this article, we offer such an overview. Evidence suggests that there are several strategies involving coverage, financing, service delivery, and governance arrangements which can, if implemented, have positive economic impacts on the delivery of primary care services. These include arrangements such as worker task-shifting and telemedicine. The implementation of any such arrangements, based on positive economic evidence, should carefully account for potential impacts on overall health care access and quality. There are many opportunities for further research, with notable gaps in evidence on the impacts of increasing primary care funding or the overall supply of primary care services. CONTEXT: the 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. To strengthen primary health care, policymakers need guidance on how to allocate resources in a manner that maximizes its economic benefits. METHODS: We collated and synthesized published systematic reviews of evidence on the economic aspects of different models of delivering primary care services. Building on previous efforts, we adapted existing taxonomies of primary care components to classify our results according to four categories: coverage, financing, service delivery, and governance. FINDINGS: We identified and classified 109 reviews that met our inclusion criteria according to our taxonomy of primary care components: coverage, financing, service delivery, and governance arrangements. A significant body of evidence suggests that several specific primary care arrangements, such as health workers' task shifting and telemedicine, can have positive economic impacts (such as lower overall health care costs). Notably absent were reviews on the impact of increasing primary care funding or the overall supply of primary care services. CONCLUSIONS: There is a great opportunity for further research to systematically examine the broader economic impacts of investing in primary care services. Despite progress over the last decade, significant evidence gaps on the economic implications of different models of primary care services remain, which could help inform the basis of future research efforts.
