Redesign and modernisation of an NHS cataract service (Fife 1997-2004): multifaceted approach

Review of referrals reveal the impact of referral content on the triage and management of ophthalmology wait lists

OBJECTIVES

Many chronic eye conditions are managed within public hospital ophthalmology clinics resulting in encumbered wait lists. Integrated care schemes can increase system capacity. In order to direct implementation of a public hospital-based integrated eye care model, this study aims to evaluate the quality of referrals for new patients through information content, assess triage decisions of newly referred patients and evaluate the consistency of referral content for new patients referred multiple times.

DESIGN

A retrospective and prospective review of all referral forms for new patients referred to a public hospital ophthalmology clinic between January 2016 and September 2017, and September 2017 and August 2018, respectively.

SETTING

A referral-only public hospital ophthalmology clinic in metropolitan Sydney, Australia.

PARTICIPANTS

418 new patients on existing non-urgent wait lists waiting to be allocated an initial appointment, and 528 patients who were newly referred.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was the information content of referrals for new patients. The secondary outcomes were triage outcomes for new incoming referrals, and the number of new patients with multiple referrals.

RESULTS

Of the wait-listed referrals, 0.2% were complete in referral content compared with 9.8% of new incoming referrals (p<0.001). Of new incoming referrals, 56.7% were triaged to a non-urgent clinic. Multiple referrals were received for 49 patients, with no change in the amount of referral content.

CONCLUSIONS

Most referrals were incomplete in content, leading to triage based on limited clinical information. Some new patients were referred multiple times with their second referral containing a similar amount of content as their first. Lengthy wait lists could be prevented by improving administrative processes and communication between the referral centre and referrers. The future implementation of an integrated eye care model at the study setting could sustainably cut wait lists for patients with chronic eye conditions.

Cataract Surgery Redesign: Meeting Increasing Demand, Training, Audit and Patient-Centered Care

Objective

The demand for cataract surgery in Fife (a well-defined region in southeast Scotland) was steadily increasing over 15 years. Cataract surgery was therefore being outsourced to meet demand with consequences on list mix, training needs, patient experience and staff morale. We aimed to redesign our services to meet local demand, retain a patient-centered service and continue to fulfil training needs.

Methods

We quantified cataract surgery delivery over an 18-month period: before, during and after redesign of services. We studied numbers of operations, trainee cases and number of outsourced cases. We also considered the economic implications of the redesign.

Results

We studied three periods (each of six months duration): before redesign (BR), redesign period (RP) and post-redesign (PR). Data were collected on total operation numbers, number of cases performed by trainees, and numbers performed out with normal working hours (weekend lists) and external providers. An economic analysis examined the cost of outsourcing cataracts during BR and RP and the costs of the redesign, including building, equipment and additional nursing staff.

Conclusion

Regional fulfilment of cataract surgery provision remains a continuous challenge within the NHS. We show that with minimal investment, smart redesign process and collaborative working, increased local provision is possible while fulfilling trainee needs and achieving the necessary clinical audits and national standards.

Day care versus in-patient surgery for age-related cataract

BACKGROUND

Age-related cataract accounts for more than 40% of cases of blindness in the world with the majority of people who are blind from cataract living in lower income countries. With the increased number of people with cataract, it is important to review the evidence on the effectiveness of day care cataract surgery.

OBJECTIVES

To provide authoritative, reliable evidence regarding the safety, feasibility, effectiveness and cost-effectiveness of day case cataract extraction by comparing clinical outcomes, cost-effectiveness, patient satisfaction or a combination of these in cataract operations performed in day care versus in-patient units.

SEARCH METHODS

We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2015, Issue 7), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to August 2015), EMBASE (January 1980 to August 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to August 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 17 August 2015.

SELECTION CRITERIA

We included randomised controlled trials comparing day care and in-patient surgery for age-related cataract. The primary outcome was the achievement of a satisfactory visual acuity six weeks after the operation.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We collected adverse effects information from the trials.

MAIN RESULTS

We included two trials. One study was conducted in the USA in 1981 (250 people randomised and completed trial) and one study conducted in Spain in 2001 (1034 randomised, 935 completed trial). Both trials used extracapsular cataract extraction techniques that are not commonly used in higher income countries now. Most of the data in this review came from the larger trial, which we judged to be at low risk of bias.The mean change in visual acuity (in Snellen lines) of the operated eye four months postoperatively was similar in people given day care surgery (mean 4.1 lines standard deviation (SD) 2.3, 464 participants) compared to people treated as in-patients (mean 4.1 lines, SD 2.2, 471 participants) (P value = 0.74). No data were available from either study on intra-operative complications.Wound leakage, intraocular pressure (IOP) and corneal oedema were reported in the first day postoperatively and at four months after surgery. There was an increased risk of high IOP in the day care group in the first day after surgery (risk ratio (RR) 3.33, 95% confidence intervals (CI) 1.21 to 9.16, 935 participants) but not at four months (RR 0.61, 95% CI 0.14 to 2.55, 935 participants). The findings for the other outcomes were inconclusive with wide CIs. There were two cases of endophthalmitis observed at four months in the day care group and none in the in-patient group. The smaller study stated that there were no infections or severe hyphaemas.In a subset of participants evaluated for quality of life (VF14 questionnaire) similar change in quality of life before and four months after surgery was observed (mean change in VF14 score: day care group 25.2, SD 21.2, 150 participants; in-patient group: 23.5, SD 25.7, 155 participants; P value = 0.30). Subjective assessment of patient satisfaction in the smaller study suggested that participants preferred to recuperate at home, were more comfortable in their familiar surroundings and enjoyed the family support that they received at home. Costs were 20% more for the in-patient group and this was attributed to higher costs for overnight stay.

AUTHORS' CONCLUSIONS

This review provides evidence that there is cost saving with day care cataract surgery compared to in-patient cataract surgery. Although effects on visual acuity and quality of life appeared similar, the evidence with respect to postoperative complications was inconclusive because the effect estimates were imprecise. Given the wide-spread adoption of day care cataract surgery, future research in cataract clinical pathways should focus on evidence provided by high quality clinical databases (registers), which would enable clinicians and healthcare planners to agree clinical and social indications for in-patient care and so make better use of resources.

Cataract surgery: factors influencing decision to treat and implications for training (south-east Scotland 2008-2014)

PURPOSE

To describe the population referred for cataract surgery, identify factors that influenced decision to treat, and patients suitable for ophthalmic training.

PATIENTS AND METHODS

A total of 2,693 consecutive referrals over 6 years were interrogated using Business Objects software on cataract electronic patient records.

RESULTS

A total of 2,693 patients were referred for cataract surgery (group A). Of these patients 2,132 (79%) had surgery (group B) and 561 (21%) did not (group C). Age for group B vs group C: 672 (32%) vs 115 (20%) ≤69 years, P<0.001; 803 (38%) vs 225 (40%) 70-79 years, P=0.48; 586 (27%) vs 203 (36%) 80-89 years, P<0.05; 71 (3%) vs 18 (3%) ≥90 years, P=1.0. Visual acuity, group B vs group C: 556 (26%) vs 664 (59%) 6/12 or better; 1,275 (60%) vs 367 (33%) 6/18-6/60; 266 (12%) vs 64 (6%) counting fingers or worse, P<0.05. Medical history for group B vs C: cognitive impairment: 55 (2.6%) vs 29 (5.2%), P<0.05; cardiovascular accident: 158 (7.4%) vs 60 (10.7%), P<0.05; diabetes: 372 (17.4%) vs 96 (17.1%), P=0.87; COPD/asthma: 382 (17.9%) vs 93 (16.6%), P=0.53; heart disease: 535 (25.1%) vs 155 (27.6%), P=0.35; hypertension: 971 (45.5%) vs 263 (46.9%), P=0.73. Ocular history for group B vs C was significant (P<0.05) for age-related macular degeneration 255 (12.0%) vs 93 (16.6%), other macular pathology 38 (1.8%) vs 25 (4.5%), corneal pathology 92 (4.3%) vs 36 (6.4%), amblyopia 37 (1.7%) vs 22 (3.9%). Detailed data on presenting complaint, ophthalmic history, and social status is discussed.

CONCLUSION

We observed that surgery at a younger age with good levels of visual acuity was a factor in deferring cataract surgery. Cognitive impairment, cardiovascular accident, amblyopia, corneal and macular pathology significantly affected decision not to operate. We estimate that 80% of patients would be suitable for ophthalmic training.

Transformational change: nurses substituting for ophthalmologists for intravitreal injections - a quality-improvement report

BACKGROUND

The dramatic increase in need for anti-vascular endothelial growth factor (anti-VEGF) intravitreal therapy in the treatment of retinal disease and the absence of an equivalent increase in ophthalmologists to undertake such intravitreal injections created a patient-safety risk. Timing of intravitreal therapy (IVT) is critical to prevent vision loss and local clinics lacked capacity to treat patients appropriately. We aimed to improve capacity for IVT by nurse injections.

MATERIALS AND METHODS

A multidisciplinary prospective service-improvement process was undertaken at two adjacent general hospitals in the northwest of England. IVT injections by nurses were a principal component of solution development. After we had obtained appropriate institutional approval, experienced ophthalmic nurses were trained, supervised, and assessed to undertake IVT. Ophthalmologists directly supervised the first 200 injections, and a retina specialist was always on site.

RESULTS

Nurses undertook 3,355 intravitreal injections between June 2012 and November 2013, with minor adverse events (0.3% subconjunctival hemorrhage and corneal abrasion). There were no patient complaints at either hospital.

CONCLUSION

Experienced ophthalmic nurses quickly learned how to perform such injections safely. IVT by nurses was well accepted by patients and staff. Hospital A trained three nurses sequentially for improved flexibility in scheduling. Novel use of appropriately trained non-medical staff can improve efficiency and access in an overburdened service with time-sensitive disease. Retinal assessment was undertaken by ophthalmologists only. Improved access to IVT is important, as treatment with anti-VEGF therapy reduces blindness at population levels.

Application of Six Sigma methodology to a cataract surgery unit

PURPOSE

The article's aim is to focus on the application of Six Sigma to minimise intraoperative and post-operative complications rates in a Turkish public hospital cataract surgery unit.

DESIGN/METHODOLOGY/APPROACH

Implementing define-measure-analyse-improve and control (DMAIC) involves process mapping, fishbone diagrams and rigorous data-collection. Failure mode and effect analysis (FMEA), pareto diagrams, control charts and process capability analysis are applied to redress cataract surgery failure root causes.

FINDINGS

Inefficient skills of assistant surgeons and technicians, low quality of IOLs used, wrong IOL placement, unsystematic sterilisation of surgery rooms and devices, and the unprioritising network system are found to be the critical drivers of intraoperative-operative and post-operative complications. Sigma level was increased from 2.60 to 3.75 subsequent to extensive training of assistant surgeons, ophthalmologists and technicians, better quality IOLs, systematic sterilisation and air-filtering, and the implementation of a more sophisticated network system.

PRACTICAL IMPLICATIONS

This article shows that Six Sigma measurement and process improvement can become the impetus for cataract unit staff to rethink their process and reduce malpractices. Measuring, recording and reporting data regularly helps them to continuously monitor their overall process and deliver safer treatments.

ORIGINALITY/VALUE

This is the first Six Sigma ophthalmology study in Turkey.

Beliefs about responsibilities, the aims of therapy and the structure of the therapy process: a qualitative study of caseload management issues in child health occupational therapy

BACKGROUND

Individual therapists' behaviour contributes to overall caseload management in therapy services. Therapists' caseload management (i.e. actions in relation to assessment, treatment and discharging) is likely to relate to their beliefs about caseload management; it may be possible to change therapists' caseload management by changing their beliefs. This study explored children's occupational therapists' beliefs about caseload management with a view to designing a caseload management intervention.

METHODS

Twenty-five therapists from six NHS Scotland Health Boards were interviewed using a semi-structured format. Interviews were transcribed verbatim, and the interview transcripts were analysed for emerging themes. A proportion of transcripts were independently read and coded, and the themes were validated through critical discussion.

RESULTS

Key issues emerged concerning therapists' beliefs about their responsibilities, the aims of therapy and the structure of the therapy process. Therapists expressed a strong sense of professional duty/responsibility, but the interpretations of what this duty/responsibility was differed between therapists. For example, therapists expressed highly contrasting beliefs about the goals and purpose of therapy and the ways in which therapy processes should be structured. Some therapists promoted an approach structured around clients' goals, while others focused more on relationship building.

CONCLUSIONS

Therapists' beliefs about caseload management differ considerably; these differences could translate to variation in therapists' intentions and behaviours. Implications for practice, policy and future research were identified, as were implications for the way clinicians' caseload management is theorized.

Day care versus in-patient surgery for age-related cataract

BACKGROUND

Age-related cataract accounts for more than 40% of cases of blindness in the world with the majority of people who are blind from cataract found in the developing world. With the increased number of people with cataract there is an urgent need for cataract surgery to be made available as a day care procedure.

OBJECTIVES

To provide reliable evidence for the safety, feasibility, effectiveness and cost-effectiveness of cataract extraction performed as day care versus in-patient procedure.

SEARCH STRATEGY

We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 5), MEDLINE (January 1950 to May 2011), EMBASE (January 1980 to May 2011), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 23 May 2011.

SELECTION CRITERIA

We included randomised controlled trials comparing day care and in-patient surgery for age-related cataract. The primary outcome was the achievement of a satisfactory visual acuity six weeks after the operation.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Adverse effects information was collected from the trials.

MAIN RESULTS

We included two trials (conducted in Spain and USA), involving 1284 people. One trial reported statistically significant differences in early postoperative complication rates in the day care group, with an increased risk of increased intraocular pressure, which had no clinical relevance to visual outcomes four months postoperatively. The mean change in visual acuity (Snellen lines) of the operated eye four months postoperatively was 4.1 (standard deviation (SD) 2.3) for the day care group and 4.1 (SD 2.2) for the in-patient group and not statistically significant. The four-month postoperative mean change in quality of life score measured using the VF14 showed minimal differences between the two groups. Costs were 20% more for the in-patient group and this was attributed to higher costs for overnight stay. One study only reported hotel costs for the non-hospitalised participants making aggregation of data on costs impossible.

AUTHORS' CONCLUSIONS

This review provides some evidence that there is a cost saving but no significant difference in outcome or risk of postoperative complications between day care and in-patient cataract surgery. This is based on one detailed and methodologically sound trial conducted in the developed world. The success, safety and cost-effectiveness of cataract surgery as a day care procedure appear to be acceptable. Future research may well focus on evidence provided by high quality clinical databases and registers which would enable clinicians and healthcare planners to agree clinical and social indications for in-patient care and so make better use of resources, by selecting day case surgery unless these criteria are met.

Clinicians' caseload management behaviours as explanatory factors in patients' length of time on caseloads: a predictive multilevel study in paediatric community occupational therapy

BACKGROUND

Long waiting times and large caseloads are a challenge to children's therapy services internationally. Research in hospital-based healthcare indicates that waiting times are a function of throughput, and that length of care episode is related to clinicians' caseload management behaviour (i.e. actions at assessment, treatment, post-treatment, and discharge). There have been few attempts to study this in community health services. The present study investigated whether community occupational therapists' behaviour predicts children's length of time (LoT) on caseloads.

METHODS

Retrospective survey of case notes of children recently discharged from occupational therapy services. Using cluster random sampling, case notes were drawn from therapy records in six NHSScotland Health Boards. Data about therapists' behaviours of assessing, treating, reviewing and discharging, together with child characteristics, were used to construct regression models of factors related to LoT.

RESULTS

Twenty-six therapists [median(IQR) time in paediatrics 8(6-13) years] and 154 of their cases [mean(SD) age 7(3) years; median(IQR) LoT 10(3-21)] were included. A multi-level model, adjusting for clustering, for therapists' actions of communicating assessment outcomes to parents, providing treatment, and placing the child on review, and for a diagnosis of cerebral palsy, explained 44% of variation in LoT.

CONCLUSIONS

Occupational therapists' caseload management behaviours are associated with children's LoT on caseloads. Further research is required to investigate the direction of relationships between therapists' behaviours and LoT; and the relationships between contextual factors, therapists' caseload management behaviours and LoT. Further exploration of therapists' beliefs about caseload management could also be useful in identifying possible factors contributing to variation between therapists.

Cataract surgery rates in latin america: a four-year longitudinal study of 19 countries

PURPOSE

To collect cataract surgery rates data in 19 Latin American countries over a 4-year period as data published to date have been limited.

METHODS

Cataract surgery rates were obtained from National Society of Ophthalmology, National VISION 2020/Prevention of Blindness Committee and Ministry of Health representatives for each country for 2005 to 2008. Economic (gross national income per capita) and other data were collected from publicly available databases. Linear and power correlations between gross national incomes and cataract surgery rates were calculated.

RESULTS

Over the study period, most countries increased their cataract surgery rates, with the largest increases observed for Venezuela (186%), Nicaragua (183%), Costa Rica (100%), Uruguay (97%), and Peru (88%). Mean cataract surgery rates for 2005, 2006, 2007, and 2008 for the ensemble of countries were 1545, 1684, 1660, and 1822 per million population, respectively, with a growth over the study period of 17.9%, concurrent with an increase of 57 million (11.5%) in the population. A good correlation between cataract surgery rate and gross national income per capita was found (P < .001).

CONCLUSIONS

Although progress is being made in the region, the cataract surgery rates represent only one parameter. When they are examined in the context of cataract surgical coverage it is clear that substantial proportions of bilaterally blind persons are still not receiving surgery.

Cataract surgery in the United Kingdom: a postal survey

PURPOSE

A postal questionnaire study to evaluate the current practice of cataract surgery delivery in the United Kingdom including strategies for postoperative review was performed.

METHODS

A cataract questionnaire was sent to all hospital departments delivering ophthalmic services in the United Kingdom based on a list from the Royal College of Ophthalmologists. It included questions about the staffing level, number of cases operated on per list, and the different strategies employed postoperatively. The results were statistically analyzed.

RESULTS

A total of 248 questionnaires were sent and 106 (43%) replies were received. The mean number of consultant teams was 11 (2-20). The average number of cases per list was 6-7 (range 4-9). In 65 hospitals, all patients are reviewed postoperatively in the hospital and some consultant teams review patients postoperatively in 18 hospitals. In 15 hospitals, patients were seen by the community optician. Most hospitals review their patients postoperatively within the first 3 weeks with more hospitals seeing them at 2-3 weeks. A wide variety of health professionals review the postoperative cases and they include doctors, nurses, and opticians (in house and community).

CONCLUSIONS

There are varied practices for cataract surgery in the United Kingdom including the number of cases on the list and postoperative review protocols. There is room for better service organization in some hospitals in terms of patient flow and better use of medical staff time to improve output.

Optimising waiting: a view from the English National Health Service

Recent authors have proposed that waiting times for elective treatment should be reduced to the point where the costs of doing so exceed the benefits. This paper considers how this criterion could be put into effect. Taking benefits first it argues that these could be estimated in three different ways - social cost benefit, clinical and user valuation - that would not necessarily produce consistent results and hence a choice has to be made between them. It then considers the costs of reducing waits and argues, citing relevant evidence, that these may range widely according to whether or not reductions can be achieved through simple management measures or whether more long-term capacity is required. It concludes therefore that the apparently simple criterion proposed for defining the point where waiting times are optimal is hard to establish. Choice of criterion must be made in the light of the overall values that a given health care system is intended to promote.

Introduction of a day-case laparoscopic cholecystectomy service in the UK: a critical analysis of factors influencing same-day discharge and contact with primary care providers

INTRODUCTION

The objective of this study was to determine the safety and acceptability of the implementation of a day-case laparoscopic cholecystectomy (LC) service in a large UK teaching hospital, and analyse factors influencing contact with primary care providers. Wide-spread introduction of day-case LC in the UK is a major target of healthcare providers. However, few centres have reported their experience. In the US, out-patient surgery for LC has been reported, though many groups have utilised 24-h observation units to facilitate discharge. Concerns remain amongst surgeons regarding the feasibility and acceptability of the introduction of day-case LC in the UK.

PATIENTS AND METHODS

Comprehensive care and operative data were prospectively collected on the first 106 consecutive day-case procedures in our hospital. Postoperative recovery was monitored by telephone questionnaire on days 2, 5 and 14, including complications, satisfaction and general practitioner consultation.

RESULTS

A total of 106 patients were admitted for day-case LC, of whom 84% were discharged on the day of surgery. Patient satisfaction rate was 94% in both the successful day-case and the admitted patients. Mean operation time was 62 min, with an average total stay on the day-care unit of 426 min. Training-grade surgeons performed 31% of operations. Both the readmission rate after surgery and rate of conversion to open surgery were 2%. Advice from primary healthcare providers was sought by 33% of patients within the first 14 postoperative days.

CONCLUSIONS

Introduction of day-case LC in the UK is feasible and acceptable to patients. The potential burden to primary care providers needs further study.

Surgery for cataract

Reorganisation of in-house services is an efficient way to improve quality and increase volume

Day care versus in-patient surgery for age-related cataract

BACKGROUND

Age-related cataract accounts for more than 40% of cases of blindness in the world with the majority of people who are blind from cataract found in the developing world. With the increased number of people with cataract there is an urgent need for cataract surgery to be made available as a day care procedure.

OBJECTIVES

To provide reliable evidence regarding the safety, feasibility, effectiveness and cost-effectiveness of cataract extraction performed as day care versus in-patient procedure.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials - CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) on The Cochrane Library (Issue 3 2004), MEDLINE (1966 to July 2004), EMBASE (1980 to August 2004) and LILACS (July 2004).

SELECTION CRITERIA

This review includes randomised controlled trials comparing day care and in-patient surgery for age-related cataract. The primary outcome was the achievement of a satisfactory visual acuity six weeks after the operation.

DATA COLLECTION AND ANALYSIS

Although two trials are included in the review, adequate data were available for only one trial and therefore pooling of data from studies was not attempted. A descriptive summary is presented.

MAIN RESULTS

Two trials, involving a total of 1284 people, are included in this review. One trial reported statistically significant differences in early postoperative complication rates in the day care group, with an increased risk of increased intraocular pressure, which had no clinical relevance to visual outcomes four months postoperatively. The mean change in visual acuity (Snellen lines) of the operated eye four months postoperatively was 4.1 (standard deviation (SD) 2.3) for the day care group and 4.1 (SD 2.2) for the in-patient group and not statistically significant. The four-month postoperative mean change in quality of life score measured using the VF14 showed minimal differences between the two groups. Costs were 20% more for the in-patient group and this was attributed to higher costs for overnight stay. One study only reported hotel costs for the non-hospitalised participants making aggregation of data on costs impossible.

AUTHORS' CONCLUSIONS

This review provides some evidence that there is a cost saving but no significant difference in outcome or risk of postoperative complications between day care and in-patient cataract surgery. This is based on one detailed and methodologically sound trial conducted in the developed world. The success, safety and cost-effectiveness of cataract surgery as a day care procedure appear to be acceptable but additional well-designed trials are required to confirm these perceptions.
