Explicit rationing of elective services: implementing the New Zealand reforms

A novel multi-criteria decision-making approach for prioritization of elective surgeries through formulation of “weighted MeNTS scoring system”

Background

Publicly funded healthcare system has long non-manageable elective surgery waiting lists due to the non-existence of systematic mathematical modelling that can assess the relative priority of patients on elective surgery waiting lists thus denying the provision of surgical support to the patients with higher urgency. Mostly the patients of general surgery are entertain with highly subjective “time-honoured” methods that are inadequate to measure and compare the urgency of surgical procedure.

Objective

A methodology of assigning priorities to patients on elective surgery waiting lists has been presented in this paper using weighted criteria objectives. The objectives hve been chosen and assigned weights based on hospital conditions, and in consultation with the surgeons in hospital in Pakistan.

Methods

The proposed methodology presents two working contributions; first, a scoring mechanism based on MeNTS scoring system with weighted criterion that objectively translate the condition of patient prior to the surgical procedure; and second, a patient prioritization methodology to select patients for surgeries according to the corresponding scores. Detailed simulation results from actual patient data have been presented to evaluate the effectiveness of the proposed methodology, and its applicability and ease of use has been tested in real-time by surgeons while providing consultations to their patients.

Results

The proposed methodology outperforms the traditional “first-come-first-serve” methodology as there was a 30% reduction in average waiting time in elective surgery waiting lists (from 4.246 to 2.956 days) with 103 (90%) of patients being entertained before or within the unprioritized surgeries time span, with 94 patients having surgery within 1 day of being on waiting list (an increase of 47 patients). Moreover, transparency and equity were also found in the adaptation of this strategy to prioritize the elective surgery patients.

Conclusions

Prioritizing patients on elective surgery waiting lists is an important concern in surgical field. In most of the methodologies presented in earlier research, prioritization of patients for surgery is carried out subjectively. This study shows that the proposed technique has the potential to decrease the waiting times for patients on elective surgery waiting lists, as well as be presented as an objective methodology for preparing the elective surgery waiting lists to increase the transparency in waiting list.

CUP study: protocol for a comparative analysis of centralised waitlist effectiveness, policies and innovations for connecting unattached patients to primary care providers

INTRODUCTION

Access to a primary care provider is a key component of high-functioning healthcare systems. In Canada, 15% of patients do not have a regular primary care provider and are classified as 'unattached'. In an effort to link unattached patients with a provider, seven Canadian provinces implemented centralised waitlists (CWLs). The effectiveness of CWLs in attaching patients to regular primary care providers is unknown. Factors influencing CWLs effectiveness, particularly across jurisdictional contexts, have yet to be confirmed.

METHODS AND ANALYSIS

A mixed methods case study will be conducted across three Canadian provinces: Ontario, Québec and Nova Scotia. Quantitatively, CWL data will be linked to administrative and provider billing data to assess the rates of patient attachment over time and delay of attachment, stratified by demographics and compared with select indicators of health service utilisation. Qualitative interviews will be conducted with policymakers, patients, and primary care providers to elicit narratives regarding the administration, use, and access of CWLs. An analysis of policy documents will be used to identify contextual factors affecting CWL effectiveness. Stakeholder dialogues will be facilitated to uncover causal pathways and identify strategies for improving patient attachment to primary care.

ETHICS AND DISSEMINATION

Approval to conduct this study has been granted in Ontario (Queens University Health Sciences and Affiliated Teaching Hospitals Research Ethics Board, file number 6028052; Western University Health Sciences Research Ethics Board, project 116591; University of Toronto Health Sciences Research Ethics Board, protocol number 40335), Québec (Centre intégré universitaire de santé et de services sociaux de l'Estrie, project number 2020-3446) and Nova Scotia (Nova Scotia Health Research Ethics Board, file number 1024979).

Designing centralized waiting lists for attachment to a primary care provider: Considerations from a logic analysis

Access to a regular primary care provider is essential to quality care. In Canada, where 15 % of patients are unattached (i.e., without a regular provider), centralized waiting lists (CWLs) help attach patients to a primary care provider (family physician or nurse practitioner). Previous studies reveal mechanisms needed for CWLs to work, but focus mostly on CWLs for specialized health care. We aim to better understand how to design CWLs for unattached patients in primary care. In this study, a logic analysis compares empirical evidence from a qualitative case study of CWLs for unattached patients in seven Canadian provinces to programme theory derived from a realist review on CWLs. Data is analyzed using context-intervention-mechanism-outcome configurations. Results identify mechanisms involved in three components of CWL design: patient registration, patient prioritization, and patient assignment to a provider for attachment. CWL programme theory is revised to integrate mechanisms specific to primary care, where patients, rather than referring providers, are responsible for registering on the CWL, where prioritization must consider a broad range of conditions and characteristics, and where long-term acceptability of attachment is important. The study provides new insight into mechanisms that enable CWLs for unattached patients to work.

Developing a prioritisation framework for patients in need of coronary artery angiography

BACKGROUND

Effective waiting list management and comprehensive prioritisation can provide timely delivery of appropriate services to ensure that the patient needs are met and increase equity in the provision of health services. We developed a prioritisation framework for patients in need of coronary artery angiography (CAA).

METHODS

We used a multi-methods approach to elicit effective factors that affect CAA patient prioritisation. Qualitative data wase collected using semi-structured interviews with 15 experts. The final set of factors was selected using experts' consensus through modifed Delphi technique. The framework was finalised during expert panel meetings.

RESULTS

212 effective factors were identified based on the literature review, interviews, and expert panel discussion of them, 37 factors were selected for modifed Delphi study. Following two rounds of Delphi discussions, seven final factors were selected and weighed by ten experts using pair-wise comparisons. The following weights were given: the severity of pain and symptoms (0.22), stress testing (0.18), background diseases (0.15), number of myocardial infarctions (0.15), waiting time (0.10), reduction of economic and social performance (0.12), and special conditions (0.08).

CONCLUSION

Clinical effective factors were important for CAA prioritisation framework. Using this framework can potentially lead to improved accountability and justice in the health system.

Effects of vitamin D supplementation on apolipoprotein A1 and B100 levels in adults: Systematic review and meta-analysis of controlled clinical trials

Cardiovascular disease (CVD) is a leading cause of death around the world. According to the studies, apolipoproteins A1 and B100 play crucial role in CVD development and progression. Also, findings have indicated the positive role of vitamin D on these factors. Thus, we conducted the present meta-analysis of randomized controlled trials (RCTs) to demonstrate the impact of vitamin D supplementation on apolipoproteins A1 and B100 levels in adults. PubMed and Scopus databases and Google Scholar were searched up to 21 December 2020. Relevant articles were screened, extracted, and assessed for quality based on the Cochrane collaboration's risk of bias tool. Data analysis conducted by random-effect model and expressed by standardized mean difference (SMD). The heterogeneity between studies was assessed by I-squared (I2) test. Subgroups and sensitivity Analyses were also conducted. Seven RCTs were identified investigating the impact of vitamin D on Apo A1 levels and six on Apo B100 levels. The findings showed the insignificant effect of vitamin D supplementation on Apo A1 (SMD=0.26 mg/dL; 95% confidence interval (CI), -0.10, 0.61; P = 0.155) and Apo B100 (standardized mean difference (SMD)=-0.06 mg/dL; 95% CI, -0.24, 0.12; P = 0.530) in adults. There was a significant between-study heterogeneity in Apo A1 (I2=89.3%, P < 0.001) and Apo B100 (I2 = 57.1%, P = 0.030). However, significant increase in Apo A1 in daily dosage of vitamin D (SMD=0.56 mg/dL; 95% CI, 0.02, 1.11; P = 0.044) and ≤12 weeks of supplementation duration (SMD=0.71 mg/dL; 95% CI, 0.08, 1.34; P = 0.028) was observed. No significant effects of vitamin D on Apo A1 and Apo B100 levels after subgroup analysis by mean age, gender, study population, dosage and duration of study. Overall, daily vitamin D supplementation and ≤12 weeks of supplementation might have beneficial effects in increasing Apo A1 levels, however, future high-quality trials considering these a primary outcome are required.

The Waiting Game - How Cooperation Between Public and Private Hospitals Can Help Reduce Waiting Lists

Prolonged waiting to access health care is a primary concern for nations aiming for comprehensive effective care, due to its adverse effects on mortality, quality of life, and government approval. Here, we propose two novel bargaining frameworks to reduce waiting lists in two-tier health care systems with local and regional actors. In particular, we assess the impact of 1) trading patients on waiting lists among hospitals, the 2) introduction of the role of private hospitals in capturing unfulfilled demand, and the 3) hospitals’ willingness to share capacity on the system performance. We calibrated our models with 2008–2018 Chilean waiting list data. If hospitals trade unattended patients, our game-theoretic models indicate a potential reduction of waiting lists of up to 37%. However, when private hospitals are introduced into the system, we found a possible reduction of waiting lists of up to 60%. Further analyses revealed a trade-off between diagnosing unserved demand and the additional expense of using private hospitals as a back-up system. In summary, our game-theoretic frameworks of waiting list management in two-tier health systems suggest that public–private cooperation can be an effective mechanism to reduce waiting lists. Further empirical and prospective evaluations are needed.

Barriers and facilitators for implementation of a patient prioritization tool in two specialized rehabilitation programs

INTRODUCTION AND AIMS

Prioritization tools aim to manage access to care by ranking patients equitably in waiting lists based on determined criteria. Patient prioritization has been studied in a wide variety of clinical health services, including rehabilitation contexts. We created a web-based patient prioritization tool (PPT) with the participation of stakeholders in two rehabilitation programs, which we aim to implement into clinical practice. Successful implementation of such innovation can be influenced by a variety of determinants. The goal of this study was to explore facilitators and barriers to the implementation of a PPT in rehabilitation programs.

METHODS

We used two questionnaires and conducted two focus groups among service providers from two rehabilitation programs. We used descriptive statistics to report results of the questionnaires and qualitative content analysis based on the Consolidated Framework for Implementation Research.

RESULTS

Key facilitators are the flexibility and relative advantage of the tool to improve clinical practices and produce beneficial outcomes for patients. Main barriers are the lack of training, financial support and human resources to sustain the implementation process.

CONCLUSION

This is the first study that highlights organizational, individual and innovation levels facilitators and barriers for the implementation of a prioritization tool from service providers' perspective.

A systematic review of patient prioritization tools in non-emergency healthcare services

BACKGROUND

Patient prioritization is a strategy used to manage access to healthcare services. Patient prioritization tools (PPT) contribute to supporting the prioritization decision process, and to its transparency and fairness. Patient prioritization tools can take various forms and are highly dependent on the particular context of application. Consequently, the sets of criteria change from one context to another, especially when used in non-emergency settings. This paper systematically synthesizes and analyzes the published evidence concerning the development and challenges related to the validation and implementation of PPTs in non-emergency settings.

METHODS

We conducted a systematic mixed studies review. We searched evidence in five databases to select articles based on eligibility criteria, and information of included articles was extracted using an extraction grid. The methodological quality of the studies was assessed by using the Mixed Methods Appraisal Tool. The article selection process, data extraction, and quality appraisal were performed by at least two reviewers independently.

RESULTS

We included 48 studies listing 34 different patient prioritization tools. Most of them are designed for managing access to elective surgeries in hospital settings. Two-thirds of the tools were investigated based on reliability or validity. Inconclusive results were found regarding the impact of PPTs on patient waiting times. Advantages associated with PPT use were found mostly in relationship to acceptability of the tools by clinicians and increased transparency and equity for patients.

CONCLUSIONS

This review describes the development and validation processes of PPTs used in non-urgent healthcare settings. Despite the large number of PPTs studied, implementation into clinical practice seems to be an open challenge. Based on the findings of this review, recommendations are proposed to develop, validate, and implement such tools in clinical settings.

How the design and implementation of centralized waiting lists influence their use and effect on access to healthcare - A realist review

CONTEXT

Many health systems have centralized waiting lists (CWLs), but there is limited evidence on CWL effectiveness and how to design and implement them.

AIM

To understand how CWLs' design and implementation influence their use and effect on access to healthcare.

METHODS

We conducted a realist review (n = 21 articles), extracting context-intervention-mechanism-outcome configurations to identify demi-regularities (i.e., recurring patterns of how CWLs work).

RESULTS

In implementing non-mandatory CWLs, acceptability to providers influences their uptake of the CWL. CWL eligibility criteria that are unclear or conflict with providers' role or judgement may result in inequities in patient registration. In CWLs that prioritize patients, providers must perceive the criteria as clear and appropriate to assess patients' level of need; otherwise, prioritization may be inconsistent. During patients' assignment to service providers, providers may select less-complex patients to obtain CWLs rewards or avoid penalties; or may select patients for other policies with stronger incentives, disregarding the established patient order and leading to inequities and limited effectiveness.

CONCLUSION

These findings highlight the need to consider provider behaviours in the four sequential CWL design components: CWL implementation, patient registration, patient prioritization and patient assignment to providers. Otherwise, CWLs may result in limited effects on access or lead to inequities in access to services.

Area deprivation and attachment to a general practitioner through centralized waiting lists: a cross-sectional study in Quebec, Canada

BACKGROUND

Access to primary healthcare is an important social determinant of health and having a regular general practitioner (GP) has been shown to improve access. In Canada, socio-economically disadvantaged patients are more likely to be unattached (i.e. not have a regular GP). In the province of Quebec, where over 30% of the population is unattached, centralized waiting lists were implemented to help patients find a GP. Our objectives were to examine the association between social and material deprivation and 1) likelihood of attachment, and 2) wait time for attachment to a GP through centralized waiting lists.

METHODS

A cross-sectional study was conducted in five local health networks in Quebec, Canada, using clinical administrative data of patients attached to a GP between June 2013 and May 2015 (n = 24, 958 patients) and patients remaining on the waiting list as of May 2015 (n = 49, 901), using clinical administrative data. Social and material area deprivation indexes were used as proxies for patients' socio-economic status. Multiple regressions were carried out to assess the association between deprivation indexes and 1) likelihood of attachment to a GP and 2) wait time for attachment. Analyses controlled for sex, age, local health network and variables related to health needs.

RESULTS

Patients from materially medium, disadvantaged and very disadvantaged areas were underrepresented on the centralized waiting lists, while patients from socially disadvantaged and very disadvantaged areas were overrepresented. Patients from very materially advantaged and advantaged areas were less likely to be attached to a GP than patients from very disadvantaged areas. With the exception of patients from socially disadvantaged areas, all other categories of social deprivation were more likely to be attached to a GP compared to patients from very disadvantaged areas. We found a pro-rich gradient in wait time for attachment to a GP, with patients from more materially advantaged areas waiting less than those from disadvantaged areas.

CONCLUSION

Our findings suggest that there are socio-economic inequities in attachment to a GP through centralized waiting lists. Policy makers should take these findings into consideration to adjust centralized waiting list processes to avoid further exacerbation of health inequities.

Centralized Waiting Lists for Unattached Patients in Primary Care: Learning from an Intervention Implemented in Seven Canadian Provinces

Introduction

Centralized waiting lists (CWLs) are one solution to reduce the problematic number of patients without a regular primary care provider. This article describes different models of CWLs for unattached patients implemented in seven Canadian provinces and identifies common issues in the implementation of these CWLs.

Methods

Logic models of each province's intervention were built after a grey literature review, 42 semi-structured interviews and a validation process with key stakeholders were performed.

Results

Our analysis across provinces showed variability and common features in the design of CWLs such as same main objective to attach patients to a primary care provider; implementation as a province-wide program with the exception of British Columbia; management at a regional level in most provinces; voluntary participation for providers except in two provinces where it was mandatory for providers to attach CWL patients; fairly similar registration process across the provinces; some forms of prioritization of patients either using simple criteria or assessing for vulnerability was performed in most provinces except New Brunswick.

Conclusion

Despite their differences in design, CWLs implemented in seven Canadian provinces face common issues and challenges regarding provider capacity to address the demand for attachment, barriers to the attachment of more vulnerable and complex patients as well as non-standardized approaches to evaluating their effectiveness. Sharing experiences across provinces as CWLs were being implemented would have fostered learning and could have helped avoid facing similar challenges.

General Surgery Prioritization Tool: a pilot study

BACKGROUND

The prioritization of elective surgical wait-lists remains a contentious issue. Multiple new tools and systems have been developed to attempt to reliably prioritize patients. This study pilots one such system, the General Surgery Prioritization Tool and compares it to the existing triage system of clinical judgement. The aim was to determine if the new tool reflects clinical judgement. Secondary aims were to assess for any bias in its application to different patient groups or its application by different scorers.

METHOD

A cohort of 392 patients was identified who were wait-listed for non-cancer elective surgery between July 2015 and February 2016. The General Surgery Prioritization Tool was applied after traditional prioritization using clinical judgement. The scores produced by the new tool were compared to the clinical judgement categories. Differences in scores based on gender, ethnicity, age, surgical condition and surgeon were then analysed.

RESULTS

There was statistically significant correlation in the new tool scores with traditional triage groups (P < 0.0001). There were no statistically significant differences in mean scores attributable to gender, age or ethnicity. There were minimal differences in mean scores between common surgical conditions. Except for one outlier the mean scores were consistent across 17 surgeons.

CONCLUSION

This pilot study has found the General Surgery Prioritization Tool to reflect clinical judgement and to be generalizable by age, gender, ethnicity and prioritizing surgeon. The tool is at least as clinically reliable as traditional methods in the triage for elective general surgery with the advantage of being a more explicit process.

Impact on hospital performance of introducing routine patient reported outcome measures in surgery

Objectives

To determine the impact of introducing patient reported outcome measures (PROMs) on the selection of patients for surgery and on outcome for four elective operations (hip replacement, knee replacement, varicose vein surgery and groin hernia repair).

Methods

Patient-level data from the National PROMs programme for England from April 2009 to March 2012 were analysed to determine the extent of change in mean preoperative scores and mean adjusted postoperative scores using disease-specific and generic PROMs assessed using standardized effect sizes (SESs). Variation between providers was determined by intra-class correlation coefficients for each time period. Consistency in outlier ratings was tested using weighted Kappa statistics.

Results

There was little apparent impact. Preoperative severity increased slightly for two procedures only: varicose vein surgery (SES disease-specific PROM 0.10; generic PROM −0.07) and to a lesser extent for hip replacement (SES disease-specific PROM −0.03). There was little inter-provider variation and it did not change significantly over time. There were also slight improvements in outcomes for hip and knee replacement (SES for disease-specific and generic PROMs 0.03) though not for hernia repair and a slight worsening for varicose vein surgery. The extent of variation in performance between providers was unchanged. The proportion of providers deemed to be outliers did not change over time. There was only moderate consistency in those providers deemed to be outliers for hip and knee replacement (Kappa 0.31–0.47) and it was even weaker for the other two procedures. Although 35% of providers of hip replacement were outliers in at least one year, only 6% were consistently outliers. Such inconsistency may be partly due to regression to the mean.

Conclusions

The minimal impact that the routine use and feedback of PROMs had on provider behaviour during the initial years suggests that more attention needs to be paid to how results are communicated and to the provision of advice as to what action may be taken.

A messy reality: an analysis of New Zealand's elective surgery scoring system via media sources, 2000-2006

Waiting lists for elective procedures are a characteristic feature of tax-funded universal health systems. New Zealand has gained a reputation for its 'booking system' for waiting list management, introduced in the early-1990s. The New Zealand system uses criteria to 'score' and then 'book' qualifying patients for surgery. This article aims to (i) describe key issues focused on by the media, (ii) identify local strategies and (iii) present evidence of variation. Newspaper sources were searched (2000-2006). A total of 1199 booking system stories were identified. Findings demonstrate, from a national system perspective, the extraordinarily difficult nature of maintaining overall control and coordination. Equity and national consistency are affected when hospitals respond to local pressure by reducing access to elective treatment. Findings suggest that central government probably needs to be closely involved in local-level management and policy adjustments; that through the study period, the New Zealand system appears to have been largely out of the control of government; and that governments elsewhere may need to be cautious when considering developing similar systems. Developing and implementing scoring and booking systems may always be a 'messy reality' with unintended consequences and throwing regional differences in service management and access into stark relief.

The (non) use of prioritisation protocols by surgeons

Priority setting and rationing is a dominant feature of contemporary health policy. In New Zealand, clinical priority assessment criteria (CPAC) tools have been developed to make access to elective surgery more equitable and efficient. Research was undertaken to identify how surgeons used these tools in the consultation. Forty-seven consultations with 15 different surgeons have to date been video- and audio-recorded. There were no instances where CPAC tools were explicitly used in the consultation. Drawing on the methodology of conversation analysis and the concept of news delivery as developed by Maynard, this paper argues that the delivery of diagnoses and treatment plans can usefully be seen in part as the delivery of bad or good news. Using three case studies to illustrate the argument, it is suggested that the interactional work required in the delivery of such news challenges the ability of clinicians to use protocols such as CPAC. The analysis sheds light on important consultation processes that need to be more carefully considered when designing interventions to influence clinician behaviour. In order to influence the behaviour of clinicians to achieve policy goals, greater attention needs to be paid to the interactional demands of the consultation process.

Public health and the cult of humanity: a neglected Durkheimian concept

Public health researchers have used a number of concepts derived from the work of Durkheim, such as anomie and social capital. One concept that has not been deployed in public health discourses is that of the cult of humanity - Durkheim's religion in a society organised around organic solidarity. This paper discusses Durkheim's views on religion and science, and the cult of humanity. The cult of humanity is characterised as having humanity at the centre of worship and combining elements of religion and science. Medicine and complementary therapies are identified as possible candidates to fulfil the role of the cult of humanity, but the institution of public health seems to be a particularly apt candidate. The paper concludes by discussing the way in which this analysis provides insight into the dual advocacy and academic functions of public health, the tension between individual choice and constraint and the buffering role of public health in relation to other social institutions.

Economic modeling of methods to stimulate quality improvement

OBJECTIVE

This paper uses an economic model to compare three methods for stimulating quality improvement: payment incentives, competition for patients, and emphasis on professional ethics.

DESIGN

Use an economic model to simulate the impact on quality distortions (risk selection) of differences in payment incentives, competition for patients, and emphasis on professional ethics.

SETTING

Health care policymakers in many countries seek to use incentives and competition to spur quality improvement. However, strong incentives often promote risk selection: insurers and providers financially benefit from distorting quality to attract profitable patients.

RESULTS

The analysis suggests that intense competition for patients and strong financial rewards for cost control can exacerbate quality distortions and compromise social solidarity.

CONCLUSIONS

Carefully regulated competition and mixed forms of provider payment (risk sharing) appear to be the best options. Moreover, designing competition, regulation, payment, and other forms of health policy to promote suppliers' professional ethics can help society to reap the quality and efficiency benefits of competition and incentives without sacrificing social solidarity.
