Sustained health-economic effects after reorganisation of a Swiss hospital emergency centre: a cost comparison study

Incidence and costs of hypoglycemia in insulin-treated diabetes in Switzerland: A health-economic analysis

AIMS

We assess the incidence and economic burden of severe and non-severe hypoglycemia in insulin-treated diabetes type 1 and 2 patients in Switzerland.

METHODS

We developed a health economic model to assess the incidence of hypoglycemia, the subsequent medical costs, and the production losses in insulin-treated diabetes patients. The model distinguishes between severity of hypoglycemia, type of diabetes, and type of medical care. We used survey data, health statistics, and health care utilization data extracted from primary studies.

RESULTS

The number of hypoglycemic events in 2017 was estimated at 1.3 million in type 1 diabetes patients and at 0.7 million in insulin-treated type 2 diabetes patients. The subsequent medical costs amount to 38 million Swiss Francs (CHF), 61 % of which occur in type 2 diabetes. Outpatient visits dominate costs in both types of diabetes. Total production losses due to hypoglycemia amount to CHF 11 million. Almost 80 % of medical costs and 39 % of production losses are due to non-severe hypoglycemia.

CONCLUSIONS

Hypoglycemia leads to substantial socio-economic burden in Switzerland. Greater attention to non-severe hypoglycemic events and to severe hypoglycemia in type 2 diabetes could have a major impact on reducing this burden.

Short- and intermediate-term effects of a hospital-integrated walk-in clinic on emergency department-visits and case mix

BACKGROUND AND IMPORTANCE

Emergency department (ED) admissions have been rising over the last decades, especially in countries without any effective gate-keeping functions. Integration of walk-in clinics into the hospital might reduce ED-visits. Over a longer period, however, the additional service of a walk-in clinic might attract even more patients, nullifying an initial decrease in patients for the ED.

OBJECTIVES, DESIGN, SETTINGS AND PARTICIPANTS

This study aimed to determine short- and intermediate-term changes after the implementation of a hospital-integrated walk-in clinic. This is an observational study using routinely-collected health data. Study setting was the ED of a large tertiary care hospital in Austria, a country with universal health care and no regulations regarding level of care.

OUTCOMES MEASURE AND ANALYSIS

ED-visits were compared between before (2015) and after (2017 and 2018) establishment of a hospital-integrated walk-in clinic.

MAIN RESULTS

Total ED-visits decreased from 87,624 in 2015 to 67,479 in 2017, and 67,871 in 2018 (p < 0.001), mainly due to a decrease in non-urgent (ESI 4 & 5) cases (45,715 (54.1%) in 2015; 33,142 (51.3%) in 2017; 30,846 (47.5%) in 2018; short term OR non-urgent vs. urgent: 0.89 (95% CI 0.88-0.91); intermediate term OR urgent vs. non-urgent: 0.76 (95% CI 0.78-0.75)). A total of 2611 (13%) (2017) and 1714 (8.5%) (2018) patients were referred back to the ED.

CONCLUSIONS

After the introduction of the walk-in clinic, ED-visits declined significantly. This remained stable over a two-year period. Reduction in ED-visits was mainly due to low-acuity patients not requiring admission to the hospital.

Adjacent Primary Care May Reduce Less Urgent Pediatric Emergency Department Visits

Aims: Pediatric emergency department (ED) overcrowding is a challenge. This study was designed to evaluate if a hospital-integrated primary care unit (HPCU) reduces less urgent visits at a pediatric ED. Methods: This retrospective cross-sectional study was carried out at a university hospital in Sweden, where the HPCU, open outside office hours, had been integrated next to the ED. Children seeking ED care during 4-week high- and low-load study periods before (2012) and after (2015) implementation of the HPCU were included. Information on patient characteristics, ED management, and length of ED stay was obtained from hospital data registers. Results: In total, 3216 and 3074 ED patient visits were recorded in 2012 and 2015, respectively. During opening hours of the HPCU, the proportions of pediatric ED visits (28% lower; P < .001), visits in the lowest triage group (36% lower; P < .001), patients presenting with fever (P = .001) or ear pain (P < .001), and nonadmitted ED patients (P = .033), were significantly lower in 2015 than in 2012, whereas the proportion of infants ≤3 months was higher in 2015 (P < .001). Conclusions: By enabling adjacent management of less urgent pediatric patients at adequate lower levels of medical care, implementation of a HPCU outside office hours may contribute to fewer and more appropriate pediatric ED visits.

Recent trends and variations in general practitioners' involvement in accident care in Switzerland: an analysis of claims data

Background

As in other countries, there is concern and some fragmentary evidence that GPs’ central role in the Swiss healthcare system as the primary provider of care might be changing or even be in decline. Our study gives a systematic account of GPs’ involvement in accident care from 2008 to 2016 and identifies changes in GPs’ involvement in this typical field of primary care: how frequently GPs were involved along the care pathway, to what extent they figured as initial care provider, and what their role in the care pathway was.

Methods

Using a claims dataset from the largest Swiss accident insurer with two million accident cases, we constructed individual care pathways, i.e., when and from which providers patients received care. We calculated probabilities for the involvement of various care provider groups, for initial care provision, and for the role of GPs in patients’ care pathways, adjusted for injury and patient characteristics using multinomial regression.

Results

In 2014, GPs were involved in 70% of all accident cases requiring outpatient care but no inpatient stay, and provided initial care in 56%. While involvement stayed at about the same level for accidents occurring from 2008 to 2014, the share of accidents where GPs provided initial care decreased by 4 percentage points. The share of cases where GPs acted as sole care provider decreased by 7 percentage points down to 44%. At the same time, accident cases involving care from an ED at any point in time increased from 38 to 46% and the share receiving initial care from an ED from 30 to 35 percentage points – apparently substituting for the declining involvement of GPs in initial care. GPs’ involvement in accident care is higher in rural compared to urban regions, among elderly compared to younger patients, and among Swiss compared to non-Swiss citizens.

Conclusions

GPs play a key role in accident care with considerable variation depending on region and patient profile. From 2008 to 2014, there is a remarkable decline in GPs’ provision of initial care after an accident. This is a strong indication that the GPs’ role in the Swiss healthcare system is changing.

Preferences for centralised emergency medical services: discrete choice experiment

OBJECTIVES

It is desirable that public preferences are established and incorporated in emergency healthcare reforms. The aim of this study was to investigate preferences for local versus centralised provision of all emergency medical services (EMS) and explore what individuals think are important considerations for EMS delivery.

DESIGN

A discrete choice experiment was conducted. The attributes used in the choice scenarios were: travel time to the hospital, waiting time to be seen, length of stay in the hospital, risks of dying, readmission and opportunity for outpatient care after emergency treatment at a local hospital.

SETTING

North East England.

PARTICIPANTS

Participants were a randomly sampled general population, aged 16 years or above recruited from Healthwatch Northumberland network database of lay members and from clinical contact with Northumbria Healthcare National Health Service Foundation Trust via Patient Experience Team.

PRIMARY AND SECONDARY OUTCOME MEASURES

Analysis used logistic regression modelling techniques to determine the preference of each attribute. Marginal rates of substitution between attributes were estimated to understand the trade-offs individuals were willing to make.

RESULTS

Responses were obtained from 148 people (62 completed a web and 86 a postal version). Respondents preferred shorter travel time to hospital, shorter waiting time, fewer number of days in hospital, low risk of death, low risk of readmission and outpatient follow-up care in their local hospital. However, individuals were willing to trade off increased travel time and waiting time for high-quality centralised care. Individuals were willing to travel 9 min more for a 1-day reduction in length of stay in the hospital, 38 min for a 1% reduction in risk of death and 112 min for having outpatient follow-up care at their local hospital.

CONCLUSIONS

People value centralised EMS if it provides higher quality care and are willing to travel further and wait longer.

Urgent care centre in Sweden-the integration of teams and perceived effects

An urgent care centre (UCC) is an upcoming trend in Swedish health care. Although UCCs have been established in other countries, their effectiveness and value have not yet been studied in Sweden. The aim of this study was to investigate the interaction between the UCC and emergency department (ED) by using validated evaluation models. One adult ED (AED) and one child ED (CED), together with a newly established UCC nearby, were included in this study. The interaction between the UCC team and the ED teams was studied by using two evaluation models: one for evaluation of integration and the other one for the evaluation of the effects, in terms of perceived relief of the ED after the establishment of the UCC. It was evident that integration was achieved early on in the course of the follow-up. However, the perception of integration varied between low (EDs) and high collaboration (UCC). All respondents of the EDs indicated relief, in terms of pace and pressure on the ED since the UCC was established. This study indicates that the grade of integration and collaboration between UCC and ED can be achieved automatically and very early during the establishment. It also shows that UCCs can be a competent complement to EDs and alleviate some of the heavy pressure placed on EDs due to ED overcrowding.

Interventions to reduce emergency department utilisation: A review of reviews

OBJECTIVE

To describe policy interventions that have the objective to reduce ED use and to estimate their effectiveness.

METHODS

Narrative review by searching three electronic databases for scientific literature review papers published between 2010 and October 2015. The quality of the included studies was assessed with AMSTAR, and a narrative synthesis of the retrieved papers was applied.

RESULTS

Twenty-three included publications described six types of interventions: (1) cost sharing; (2) strengthening primary care; (3) pre-hospital diversion (including telephone triage); (4) coordination; (5) education and self-management support; (6) barriers to access emergency departments. The high number of interventions, the divergent methods used to measure outcomes and the different populations complicate their evaluation. Although approximately two-thirds of the primary studies showed reductions in ED use for most interventions the evidence showed contradictory results.

CONCLUSION

Despite numerous publications, evidence about the effectiveness of interventions that aim to reduce ED use remains insufficient. Studies on more homogeneous patient groups with a clearly described intervention and control group are needed to determine for which specific target group what type of intervention is most successful and how the intervention should be designed. The effective use of ED services in general is a complex and multi-factorial problem that requires integrated interventions that will have to be adapted to the specific context of a country with a feedback system to monitor its (un-)intended consequences. Yet, the co-location of GP posts and emergency departments seems together with the introduction of telephone triage systems the preferred interventions to reduce inappropriate ED visits while case-management might reduce the number of ED attendances by frequent ED users.

Referral outcomes of attendances at general practitioner led urgent care centres in London, England: retrospective analysis of hospital administrative data

OBJECTIVE

To identify patient and attendance characteristics that are associated with onwards referral to co-located emergency departments (EDs) or other hospital specialty departments from general practitioner (GP) led urgent care centres (UCCs) in northwest London, England.

METHODS

We conducted a retrospective analysis of administrative data recorded in the UCCs at Charing Cross and Hammersmith Hospitals, in northwest London, from October 2009 to December 2012. Attendances made by adults resident in England were included. Logistic regression was used to model the associations between the explanatory variables-age; sex; ethnicity; socioeconomic status; area of residence; distance to UCC; GP registration; time, day, quarter, year; and UCC of attendance-and the outcome of onwards referral to the co-located EDs or other hospital specialty departments.

RESULTS

Of 243 042 included attendances, 74.1% were managed solely within the UCCs without same day referral to the EDs (16.8%) or other hospital specialty departments (5.7%), or deferred referral to a fracture, hand management or soft tissue injury management clinic (3.3%). The adjusted odds of onwards referral was estimated to increase by 19% (OR 1.19, 95% CI 1.18 to 1.19) for a 10 year increase in a patient's age. Men, patients registered with a GP and residents of less socioeconomically deprived areas were also more likely to be referred onwards from the UCCs.

CONCLUSIONS

The majority of patients, across each category of all explanatory variables, were managed solely within the UCCs, although a large absolute number of patients were referred onwards each year. Several characteristics of patients and their attendances were associated with the outcome variable.
