Driving Efficiency Improvement (EI): Exploratory Analysis of a Centralised Model in New South Wales

Introduction

Public healthcare systems face rising demand coupled with reducing funding growth rates, necessitating ongoing approaches to efficiency improvement (EI). Centrally coordinated EI approaches l may support EI leaders, yet few such approaches exist internationally. This study provides evidence to inform system-wide EI by harnessing understanding of the perceptions, role demands and support requirements of key EI stakeholders in the centralised EI model implemented in New South Wales.

Methods

A purposive sample of key informants within NSW Health with responsibility for EI in their organisation were invited to participate. Semi-structured interviews were conducted, recorded and transcribed. A thematic analysis was undertaken using a theoretical deductive approach.

Results

Seventeen respondents participated who occupied EI leadership roles in metro (8) and rural (6) health services as well as non-clinical support (3) services. Four primary themes emerged on the perceptions and experiences of participants in 1. holding a unique skillset which enables them to undertake EI; 2. inheriting EI accountabilities as additional duties rather than holding dedicated EI roles; 3. the importance of senior support for EI success; and 4. feelings of isolation in undertaking EI. An additional underpinning theme that EI is not well conceptualized in public health systems also emerged, whereby EI planners felt that frontline staff generally do not consider efficiency as a component of their duties.

Conclusion

EI leaders provide points of authority, experience and influence across organisations within public health systems. This study finds that EI planners possess a unique skillset, can feel isolated both within their health organisation and within the broader public health system and believe that EI is poorly conceptualized amongst health staff. Centralised support for EI stakeholders across a public health system can promote knowledge sharing and capability development. Addressing the role and support requirements of key EI stakeholders is essential.

Supporting efficiency improvement in public health systems: a rapid evidence synthesis

Background

Public health systems internationally are under pressure to meet increasing demand for healthcare in the context of increasing financial resource constraint. There is therefore a need to maximise health outcomes achieved with public healthcare expenditure. This paper aims to establish and synthesize the contemporary evidence base for approaches taken at a system management level to improve efficiency.

Methods

Rapid Evidence Assessment (REA) methodology was employed. A search strategy was developed and applied (PUBMED, MEDLINE) returning 5,377 unique titles. 172 full-text articles were screened to determine relevance with 82 publications included in the final review. Data regarding country, study design, key findings and approaches to efficiency improvement were extracted and a narrative synthesis produced. Publications covering health systems from developed countries were included.

Results

Identified study designs included policy reviews, qualitative reviews, mixed methods reviews, systematic reviews, literature reviews, retrospective analyses, scoping reviews, narrative papers, regression analyses and opinion papers. While findings revealed no comprehensive frameworks for system-wide efficiency improvement, a range of specific centrally led improvement approaches were identified. Elements associated with success in current approaches included dedicated central functions to drive system-wide efficiency improvement, managing efficiency in tandem with quality and value, and inclusive stakeholder engagement.

Conclusions

The requirement for public health systems to improve efficiency is likely to continue to increase. Reactive cost-cutting measures and short-term initiatives aimed only at reducing expenditure are unlikely to deliver sustainable efficiency improvement. By providing dedicated central system-wide efficiency improvement support, public health system management entities can deliver improved financial, health service and stakeholder outcomes.

Matching the production of doctors with national needs

CONTEXT

Matching the supply of health workers to need is necessary if a health system is to be sustainable, affordable and fit for purpose. On the 30th anniversary of the 1988 Edinburgh Declaration of the World Federation for Medical Education, levels of compliance with the 10th recommendation, 'Ensure admission policies that match the numbers of students trained with national needs for doctors', warrant review. There are two domains to such a review, concerning, respectively, how well these health needs are known, and whether workforce supply is well matched.

METHODS

This is a literature review-based analysis of extant health system planning, which underpins current understanding of national health needs and of the consequent alignment of student selection processes.

RESULTS

The core finding is that national need for doctors, and any other health workers, is not confidently known for any jurisdiction. Consequently, validation of student selection processes is impossible against this endpoint and data to validate these processes against the alternative endpoint of a positive impact on health outcomes do not exist. Data do exist to suggest some student selection processes result in desirable career and career location uptakes.

Creation of an Online Wiki Improves Post-Operative Surgical Protocol Adherence in Arthroplasty Patients

BACKGROUND

Perioperative care pathways are tools used in high-volume clinical settings to standardize care, reduce variability, and improve outcomes. However, the mechanism by which the information is transmitted to other caregivers is often inconsistent and error-prone. At our institution, we developed an online, user-editable ("wiki") database to communicate post-operative protocols. The purpose of this study is to evaluate the hypothesis that implementation of the wiki would improve protocol adherence and reduce unintentional deviations inpatient care.

METHODS

We conducted a retrospective review of patients who underwent primary lower extremity arthroplasty at our institution during three 6-month time periods including immediately before, 6 months after, and 2 years following introduction of the wiki. Adherence to defined perioperative care pathways (laboratory studies, post-operative imaging, perioperative antibiotics, and inpatient pain medications) was compared between the groups.

RESULTS

After wiki implementation, adherence to protocols improved significantly for laboratory orders (P < .0001), imaging (P < .001), pain control regimen (P = .03), and overall protocol adherence (P < .001). Improvements were seen in some areas almost immediately, while others did not show improvements until 2 years after implementation. Costs associated with unnecessary testing were reduced by 82%.

CONCLUSION

Development of an online wiki for tracking post-operative protocols improves care pathway adherence and reduces variability in care while lowering costs associated with unnecessary testing, although some benefits may not be immediately realized. Several practical barriers to implementing the wiki are also discussed, along with proposed solutions.

Total hip replacement and surface replacement for the treatment of pain and disability resulting from end-stage arthritis of the hip (review of technology appraisal guidance 2 and 44): systematic review and economic evaluation

BACKGROUND

Total hip replacement (THR) involves the replacement of a damaged hip joint with an artificial hip prosthesis. Resurfacing arthroplasty (RS) involves replacement of the joint surface of the femoral head with a metal surface covering.

OBJECTIVES

To undertake clinical effectiveness and cost-effectiveness analysis of different types of THR and RS for the treatment of pain and disability in people with end-stage arthritis of the hip, in particular to compare the clinical effectiveness and cost-effectiveness of (1) different types of primary THR and RS for people in whom both procedures are suitable and (2) different types of primary THR for people who are not suitable for hip RS.

DATA SOURCES

Electronic databases including MEDLINE, EMBASE, The Cochrane Library, Current Controlled Trials and UK Clinical Research Network (UKCRN) Portfolio Database were searched in December 2012, with searches limited to publications from 2008 and sample sizes of ≥ 100 participants. Reference lists and websites of manufacturers and professional organisations were also screened.

REVIEW METHODS

Systematic reviews of the literature were undertaken to appraise the clinical effectiveness and cost-effectiveness of different types of THR and RS for people with end-stage arthritis of the hip. Included randomised controlled trials (RCTs) and systematic reviews were data extracted and risk of bias and methodological quality were independently assessed by two reviewers using the Cochrane Collaboration risk of bias tool and the Assessment of Multiple Systematic Reviews (AMSTAR) tool. A Markov multistate model was developed for the economic evaluation of the technologies. Sensitivity analyses stratified by sex and controlled for age were carried out to assess the robustness of the results.

RESULTS

A total of 2469 records were screened of which 37 were included, representing 16 RCTs and eight systematic reviews. The mean post-THR Harris Hip Score measured at different follow-up times (from 6 months to 10 years) did not differ between THR groups, including between cross-linked polyethylene and traditional polyethylene cup liners (pooled mean difference 2.29, 95% confidence interval -0.88 to 5.45). Five systematic reviews reported evidence on different types of THR (cemented vs. cementless cup fixation and implant articulation materials) but these reviews were inconclusive. Eleven cost-effectiveness studies were included; four provided relevant cost and utility data for the model. Thirty registry studies were included, with no studies reporting better implant survival for RS than for all types of THR. For all analyses, mean costs for RS were higher than those for THR and mean quality-adjusted life-years (QALYs) were lower. The incremental cost-effectiveness ratio for RS was dominated by THR, that is, THR was cheaper and more effective than RS (for a lifetime horizon in the base-case analysis, the incremental cost of RS was £11,284 and the incremental QALYs were -0.0879). For all age and sex groups RS remained clearly dominated by THR. Cost-effectiveness acceptability curves showed that, for all patients, THR was almost 100% cost-effective at any willingness-to-pay level. There were age and sex differences in the populations with different types of THR and variations in revision rates (from 1.6% to 3.5% at 9 years). For the base-case analysis, for all age and sex groups and a lifetime horizon, mean costs for category E (cemented components with a polyethylene-on-ceramic articulation) were slightly lower and mean QALYs for category E were slightly higher than those for all other THR categories in both deterministic and probabilistic analyses. Hence, category E dominated the other four categories. Sensitivity analysis using an age- and sex-adjusted log-normal model demonstrated that, over a lifetime horizon and at a willingness-to-pay threshold of £20,000 per QALY, categories A and E were equally likely (50%) to be cost-effective.

LIMITATIONS

A large proportion of the included studies were inconclusive because of poor reporting, missing data, inconsistent results and/or great uncertainty in the treatment effect estimates. This warrants cautious interpretation of the findings. The evidence on complications was scarce, which may be because of the absence or rarity of these events or because of under-reporting. The poor reporting meant that it was not possible to explore contextual factors that might have influenced study results and also reduced the applicability of the findings to routine clinical practice in the UK. The scope of the review was limited to evidence published in English in 2008 or later, which could be interpreted as a weakness; however, systematic reviews would provide summary evidence for studies published before 2008.

CONCLUSIONS

Compared with THR, revision rates for RS were higher, mean costs for RS were higher and mean QALYs gained were lower; RS was dominated by THR. Similar results were obtained in the deterministic and probabilistic analyses and for all age and sex groups THR was almost 100% cost-effective at any willingness-to-pay level. Revision rates for all types of THR were low. Category A THR (cemented components with a polyethylene-on-metal articulation) was more cost-effective for older age groups. However, across all age-sex groups combined, the mean cost for category E THR (cemented components with a polyethylene-on-ceramic articulation) was slightly lower and the mean QALYs gained were slightly higher. Category E therefore dominated the other four categories. Certain types of THR appeared to confer some benefit, including larger femoral head sizes, use of a cemented cup, use of a cross-linked polyethylene cup liner and a ceramic-on-ceramic as opposed to a metal-on-polyethylene articulation. Further RCTs with long-term follow-up are needed.

Quality in orthopaedic surgery--an international perspective: AOA critical issues

Quality is a hallmark of health care, although it is difficult to come to a consensus on who gets to define what "quality health care" is. Most health-care workers enter this field with the goal of improving the health of their patients (and the community), and while everyone tries to do the best job possible, we must continuously seek better methods and techniques for achieving better outcomes. The passion for continuous improvement is fundamental, but passion is not sufficient by itself. There is substantial opportunity to improve quality and reduce cost in health care. Multidisciplinary teams that include physicians, nurses, and other ancillary care providers have led to decreased waiting times to see specialists and have also led to better management of chronic disease. By including ancillary care, providers can increase cancer-screening rates and have the potential to decrease readmissions. Moreover, the addition of hospitalists and physician assistants can produce quality and efficiency outcomes that are commensurate with those enjoyed by traditional house staff. However, truly improving performance is difficult due to questions about how we define "quality," design care processes, measure inputs and outputs, develop multi-stakeholder collaborations, and develop incentive programs for delivering "good" care. There is a definite need for more thorough and robust studies of the impact of pay-for-performance programs, with the inclusion of ancillary care providers. Current research has not shown that there is not enough evidence to be able to determine what incentive structure might "work" in a particular health-care system. Payment systems will continue to evolve to incentivize greater collaboration among providers to yield higher-quality, lower-cost care. Future efforts will necessitate the need for strong physician leadership in helping to develop an optimal care team that is as patient-centered as possible. Technology adds dimensions of capability to making improvement real and systematic, as well as providing safer care with fewer errors and better adherence to proven best practices. The drive for quality with technology produces better clinical outcomes and maximizes efficiencies and financial metrics of organizational performance. Technology also adds capabilities for capturing key metrics and reporting them back to clinicians and others. Improved data transparency informs those who can actually do things differently to produce better results and outcomes. While health-care entities strive to focus on quality of care, measuring and reporting such care in a meaningful way are difficult. The best chance of improving overall care for patients is through the adoption of systems that improve coordination and continuity, not by health-care staff working harder. Only through collaboration and integration can health care incorporate a culture for improving quality and patient safety.

Improving the productivity of elective surgery through a new 'package of care'

In response to a need to improve the productivity and throughput of elective surgical services, one district health board (DHB) in New Zealand has introduced a 'package of care' (POC) in which incentive-based, risk-sharing contracts were developed collaboratively between DHB managers, surgeons and anaesthetists. The POC includes throughput targets and facilitates consistent surgical teams and the cohorting of patients. Whilst many staff are very supportive of the POC, some are of the view that it conflicts with the ideals and principles of working in a public health system, and creates inequities amongst the hospital staff. Analysis indicates that, after controlling for age, casemix and complexity the POC has resulted in shorter theatre times, shorter lengths of stay and lower average inpatient event costs compared with standard care at the public hospital. An unintended consequence could be that the POC may encourage throughput of less complex cases at the expense of more complex cases. The average complexity and range of cases performed publicly should be carefully monitored to ensure this does not occur.
