Patient experiences and perspectives of health service access for carpal tunnel syndrome in Aotearoa New Zealand: a normalisation process theory-informed qualitative study

BACKGROUND

Early access to care for carpal tunnel syndrome (CTS) can avoid higher rates of surgery and permanent harm yet is often delayed, particularly for populations more likely to underutilise care.

OBJECTIVE

We sought to explore patient experiences and perspectives of health service access for CTS to inform an equity-focussed co-design of a health service for improving early care access.

METHODS

In this Normalisation Process Theory (NPT)-informed qualitative study we conducted semistructured in-depth interviews with 19 adults with experience of CTS. Recruitment prioritised New Zealand Māori, Pasifika, low-income, and rural populations. Data were analysed using deductive then inductive thematic analysis.

RESULTS

We identified five major themes: (1) the 'Significant Impact of CTS' of the sense-making and relational work to understand the condition, deciding when to get care, compelling clinicians to provide care, and garnering help from others; (2) 'Waiting and Paying for Care'- the enacting, relational, and appraising work to avoid long wait times unless paying privately, particularly where quality of care was low, employment relations poor, or injury compensation processes faltered; (3) circumstances of 'Occupation and CTS Onset' whereby the burden of proof to relate onset of CT symptoms to occupation created excessive relational and enacting work; (4) the 'Information Scarcity' of good information about CTS and the high relational and appraising work associated with using online resources; (5) 'Negotiating Telehealth Perspectives' where telehealth was valued if it meant earlier access for all despite the challenges it held for many.

CONCLUSION

Quality, culturally and linguistically responsive information and communication from clinicians and health services will improve equitable early access to CTS care including realising the potential of telehealth modes of care. Policy changes that reduce individual burden of proof in injury compensation claims processes, enable time off work to attend health appointments, and increase public funding for surgical resources would improve early access to CTS care particularly for Māori and Pacific populations and those in small and rural workplaces. NPT is valuable for understanding where opportunities lie to reduce inequitable delays to accessing care including the impact of racism, particularly for populations more likely to underutilise care.

Clinicians' Experiences and Perspectives about a New Lung Cancer Referral Pathway in a Regional Health Service

Introduction

Development and implementation of the Townsville Lung Cancer Referral Pathway [TLCRP] aims to reduce delays and improve referral patterns of people with suspected lung cancer in north Queensland, Australia. Reported in this paper is the experiences and perspectives of general practitioners [GPs] and specialists of the TLCRP.

Methods

This was a descriptive qualitative study nested within a larger project evaluating TLCRP, utilising a broader implementation science framework. In-depth, semi-structured interviews with GPs and specialists were conducted. An iterative, inductive thematic analysis of interview transcripts was used to derive key codes, then grouped into themes regarding participant experiences and perceptions.

Results

Data analysis identified two major themes and several sub-themes. The major themes were variation in the uptake of TLCRP and enhancing coordinated care and communication.

Discussion

Several enablers and barriers to implementing TLCRP were identified. Barriers to adaptation of TLCRP included lack of clinical time, resistance to changing referral patterns, lack of familiarity or experience with HealthPathways and technology issues.

Conclusion

Emerging themes from this study may be used to reduce the barriers and improve uptake of TLCRP and other health care pathways in the local health service and may have wider relevance in other settings.

Cardiac interventions in Wales: A comparison of benefits between NHS Wales specialties

OBJECTIVES

The study aimed to assess if specialised healthcare service interventions in Wales benefit the population equitably in work commissioned by the Welsh Health Specialised Services Committee (WHSSC).

APPROACH

The study utilised anonymised individual-level, population-scale, routinely collected electronic health record (EHR) data held in the Secure Anonymised Information Linkage (SAIL) Databank to identify patients resident in Wales receiving specialist cardiac interventions. Measurement was undertaken of associated patient outcomes 2-years before and after the intervention (minus a 6-month clearance period on either side) by measuring events in primary care, hospital attendance, outpatient and emergency department. The analysis controlled for comorbidity (Charlson) and deprivation (Welsh Index of Multiple Deprivation), stratified by admission type (elective or emergency) and membership of top 5% post-intervention costs. Costs were estimated by multiplying events by mean person cost estimates.

RESULTS

We identified 5,999 percutaneous coronary interventions (PCI) and 1,640 coronary artery bypass graft (CABG) between 2014-06-01 to 2020-02-29. The ratio of emergency to elective interventions was 2.85 for PCI and 1.04 for CABG. In multivariate analysis significant associations were identified for comorbidity (OR = 1.52, CI = (1.01-2.27)), deprivation (OR = 1.34, CI = (1.03-1.76)) and rurality (OR = 0.81, CI = (0.70-0.95)) for PCI interventions, and comorbidity (OR = 1.47, CI = (1.10-1.98)) for CABG. Higher costs post-intervention were associated with increased comorbidity for PCI and CABG in the top 5% cost groups, but for PCI this was not seen outside the top 5%. For PCI, moderate cost increase was associated with increased deprivation, but the picture was more mixed following CABG interventions. For both interventions, lower costs post intervention were seen in rural locations.

CONCLUSION

We identified and compared health outcomes for selected specialist cardiac interventions amongst patients resident in Wales, with these methods and analyses, providing a template for comparing other cardiac interventions.

Impact and outcome evaluation of HealthPathways: a scoping review of published methodologies

INTRODUCTION The HealthPathways programme is an online health information system used mainly in primary health care to promote a consistent and integrated approach to patient care. AIM The aim of this study is to perform a scoping review of the methodologies used in published impact and outcomes evaluations of HealthPathways programmes. METHODS The review included qualitative, quantitative or mixed-methods evaluations of the impact or outcome of HealthPathways. MEDLINE, Embase, CINAHL and Web of Science databases were searched. Seven programme aims were identified in the impact and outcome evaluation: (1) increased awareness and use of HealthPathways; (2) general practitioners are supported to adopt best practice, patient-centred care; (3) increased appropriate use of resources and services; (4) improved quality of referrals; (5) enhanced consistent care and management of health conditions; (6) improved patient journeys through the local health system; and (7) reduction in health-care cost and increased value for money. RESULTS Twenty-one studies were included in the final review; 15 were research papers and six were reports. 'Increased awareness and use of HealthPathways' was the most frequent programme aim evaluated (n = 12). Quantitative and qualitative research methodologies, as well as prospective and retrospective data collections, have been adopted to evaluate the impact and outcome of HealthPathways. DISCUSSION Assessing the impacts and outcomes of HealthPathways may be challenging due to limitations in primary data and the interconnectedness of change across the measured aims. Each aim may therefore require specific methodologies sensitive enough to capture the impact that HealthPathways are making over time.

Economic Analysis of Specialist Referral Patterns in Mackay, Queensland Following HealthPathways Implementation

INTRODUCTION

HealthPathways is a clinical information portal developed in New Zealand that enables general practitioners to manage and refer their patients in a local context. We analyzed specialist outpatient appointment costs in Mackay, Queensland before and after HealthPathways implementation.

METHODS

We retrospectively examined specialist outpatient costs for patients referred by Mackay general practitioners for conditions with varying levels of HealthPathways implementation. Ranked from most clinical pathways available to none, chronic diabetes, cardiology, respiratory, and urology visits from January to March 2015, pre-pathways, and January to March 2017, post-pathways, were assessed. Monte Carlo simulation was used to estimate cost changes. Per-visit costs were multiplied by visit numbers to estimate policy impact.

RESULTS

The mean cost per visit increased from $220 to $305 for diabetes and $270 to $323 for respiratory, and decreased from $296 to $257 for cardiology and $444 to $293 for urology. The policy impact for each disease group over 3 months after accounting for visit numbers was a likely saving of $30 360 for diabetes and $10 270 for cardiology, and a likely cost increase of $24 449 for respiratory and $20 536 for urology.

CONCLUSIONS

We observed that conditions with more comprehensive clinical pathways cost Mackay HHS substantially less following implementation. Costs for low and no pathway implementation referrals increased slightly over the same period.
