Effectiveness of a quality improvement collaborative in reducing time to surgery for patients requiring emergency cholecystectomy

Outcomes after index cholecystectomy: a UK longitudinal multi-centre cohort Study

PURPOSE

International guidelines for management of acute biliary pathology recommend emergency cholecystectomy (EmC), citing improved outcomes compared to elective cholecystectomy (ElC) based on trials which may not reflect the capacity constraints in clinical practice, nor selection based on multiple prior attendances with emergency biliary pathology or attendances following a decision for ElC. We therefore conducted a longitudinal retrospective study evaluating all attendances with biliary pathology prior to cholecystectomy with the aim of assessing whether EmC is justified in this context.

METHODS

Data was collected on patients undergoing cholecystectomy between 2016 and 2021 at four centres. Patients who had an emergency presentation with a biliary pathology prior to cholecystectomy up to 2010 were included. Patients were divided into EmC and ElC groups, EmC was defined as cholecystectomy occurring during an emergency admission with biliary pathology. Multilevel regression modelling was used to identify independent predictors for time to surgery from index presentation, number of re-attendances and length of stay (LoS).

RESULTS

2,056 patients were included: 1,786 (86.9%) had ElC and 270 (13.1%) EmC. EmC was independently associated with a reduction in time to surgery (-112.32 days [95% CI -140.22 to -84.42]). However, there was a significant increase in both post-operative and overall LoS (+ 3.34 days [95% CI 1.81-4.86]) across all admissions with EmC. EmC did not significantly reduce rates of emergency re-attendance prior to surgery overall.

CONCLUSION

Although EmC reduces time to surgery, it does not reduce the number of emergency re-attendances and increases LoS. In the context of limited emergency theatre capacity, it may be beneficial to prioritise those who benefit most from EmC.

Management and patient outcomes following admission with acute cholecystitis in Ireland: A national registry-based study

INTRODUCTION

Acute cholecystitis is a common general surgical emergency, accounting for 3-10 % of all patients attending with acute abdominal pain. International guidelines suggest that emergency cholecystectomy is the treatment of choice for uncomplicated acute cholecystitis where feasible. There is a paucity of published data on the uptake of emergency cholecystectomy in Ireland.

AIM

The aim of this study was to evaluate the management of acute cholecystitis in Ireland and to establish the rate of emergency cholecystectomy performed.

METHODS

All patients with acute cholecystitis presenting to public hospitals in Ireland between January 2017 and July 2023 were identified using the National Quality Assurance and Improvement System (NQAIS). Data were collected on patient demographics, co-morbidities, length of stay, operative intervention, endoscopic intervention, critical care admissions, in-patient mortality, and readmissions. Propensity score matched analysis and logistic regression were performed to account for selection bias in comparing patients managed with cholecystectomy and those managed conservatively.

RESULTS

20,886 admission episodes were identified involving 17,958 patients. 3585 (20 %) patients underwent emergency cholecystectomy in total. 3436 (96 %) of these were performed laparoscopically, with 140 (4 %) requiring conversion to an open procedure, and common bile duct injuries occurring in 4 (0.1 %) of patients. In comparison to patients treated conservatively, patients who underwent cholecystectomy were younger (median 50 v 60 years, p < 0.001) and more likely to be female (64 % v 55 % p < 0.001). Following propensity score matched analysis, those who had an emergency cholecystectomy had reduced length of stay (LOS) (median 5 days (IQR 3-8) v 6 days (interquartile range (IQR) 3-10), p < 0.001) and fewer readmissions to hospital (282 (8 %) v 492 (14 %), p < 0.001). On logistic regression, age >65 (OR 1.526), CCI >3 (OR 2.281) and non-operative management (OR 1.136) were significant risk factors for adverse outcome.

CONCLUSION

Uptake of emergency cholecystectomy in Ireland remains low, and is carried out on a younger, fitter cohort of patients. In those patients, however, it is associated with improved outcomes for cholecystitis compared to conservative management, including shorter LOS and reduced readmission rates for matched cohorts.

Audit of Emergency Laparoscopic Cholecystectomy in a District General Hospital

Introduction  Acute gallstone diseases are common surgical emergencies, accounting for approximately one-third of emergency surgical admissions. Laparoscopic cholecystectomy is the standard choice of treatment for gallstone diseases and is currently one of the most commonly performed surgical procedures in the United Kingdom. Majority of these procedures are carried out as elective cases. National Institute of Clinical Excellence (NICE) guidelines and other upper gastrointestinal surgery specialty bodies encourage early emergency surgery in acute symptomatic gallstone disease. We assessed emergency laparoscopic cholecystectomies performed at Birmingham Heartlands Hospital, United Kingdom and compared the practice against NICE and British Benign Upper Gastrointestinal Surgery Society (BBUGSS) recommendations. Methods This is a snapshot retrospective audit, assessing emergency laparoscopic cholecystectomy practice over a nine-month period from November 2022 to July 2023. Variables assessed were demographics, duration of symptoms prior to surgery, imaging modality, indications, C-reactive protein (CRP) levels, operative difficulty, intraoperative and postoperative complications, length of hospital stay and readmission rates. These variables were compared against both NICE and BBUGSS standards. We aimed to establish baseline data to encourage emergency laparoscopic cholecystectomies in our hospital and reduce repeated hospital visits for patients with acute gallbladder disease. Results Forty-eight patients had emergency laparoscopic cholecystectomy in the period reviewed, mean age was 44.3 years and females accounted for approximately 71% (n=34) of the group. 66.7% (n=32) of patients had their surgery within seven days of diagnosis with acute gallstone disease; 50% (n=24) of patients had no adverse intraoperative event. No patient had biliary tract injury despite a high number of difficult cases. Overall there was no correlation between duration before surgery and intraoperative difficulty or readmission rates.

Effectiveness of quality improvement collaboratives in UK surgical settings and barriers and facilitators influencing their implementation: a systematic review and evidence synthesis

BACKGROUND

High-quality surgical care is vital to deliver the excellent outcomes patients deserve following surgical treatment. Quality improvement collaboratives (QICs) are based on a multicentre model for improving healthcare. They are increasingly used but their effectiveness in the context of surgical services is unclear. This review assessed effectiveness of QICs in National Health Service (NHS) surgical settings, and identified factors that influenced implementation.

METHODS

A systematic search of MEDLINE and EMBASE, as well as grey literature, was conducted in January 2022 to identify evaluations of QICs in NHS surgical settings. Data were extracted on the intervention, setting, study results and factors that were identified as facilitators or barriers. These were coded using the Consolidated Framework for Implementation Research (CFIR). The quality of study reports was assessed using Quality Improvement Minimum Criteria Set.

RESULTS

Fifteen reports on 10 QICs met inclusion criteria. The evaluations used study designs of different strength, with one using a stepped-wedge randomised controlled trial (RCT). Eight studies reported the QIC had been successful in achieving their principal aims, which covered a mix of patient outcomes and process indicators. The study based on the RCT found the QIC was not successful (no improvement in patient outcomes). Each article reported a range of facilitators and barriers to effectiveness of implementation of the QIC, which were spread across the CFIR domains (intervention, outer setting, inner setting, individuals and process). There were few barriers reported in the intervention domain that related to the QIC. There was no clear relationship between numbers of facilitators and barriers reported and effectiveness.

CONCLUSIONS

Studies have reported QICs to be effective in increasingly complex contexts, but their results must be treated with caution. The evaluations often used weak study designs and the quality of reports was variable. Evaluation with strong study design should be integral to future QICs.

Specialist-led urgent cholecystectomy for acute gallstone disease

BACKGROUND

Despite overwhelming evidence of the clinical and financial benefit of urgent cholecystectomy, there is variable enthusiasm and uptake across the UK. In 2014, following the First National Emergency Laparotomy Audit Organisational Report, we implemented a specialist-led urgent surgery service, whereby all patients with gallstone-related pathologies were admitted under the direct care of specialist upper gastrointestinal surgeons. We have analysed 5 years of data to investigate the results of this service model.

METHODS

Computerised operating theatre records were interrogated to identify all patients within a 5-year period undergoing cholecystectomy. Patient demographics, admission details, length of stay, duration of surgery, and complications were analysed.

RESULTS

Between 01/01/2016 and 31/12/2020, a total of 4870 cholecystectomies were performed; 1793 (36.8%) were urgent cases and 3077 (63.2%) were elective cases. All cases were started laparoscopically; 25 (0.5%) were converted to open surgery-14 of 1793 (0.78%) urgent cases and 11 of 3077 (0.36%) elective cases. Urgent cholecystectomy took 20 min longer than elective surgery (median 74 versus 52 min). No relevant difference in conversion rate was observed when urgent cholecystectomy was performed within 2 days, between 2 and 4 days, or greater than 4 days from admission (P = 0.197). Median total hospital stay was 4 days.

CONCLUSION

Urgent laparoscopic cholecystectomy is safe and feasible in most patients with acute gall bladder disease. Surgery under the direct care of upper gastrointestinal specialist surgeons is associated with a low conversion rate, low complication rate, and short hospital stay. Timing of surgery has no effect on conversion rate or complication rate.

Clinical effectiveness and cost-effectiveness of emergency surgery for adult emergency hospital admissions with common acute gastrointestinal conditions: the ESORT study

Background

Evidence is required on the clinical effectiveness and cost-effectiveness of emergency surgery compared with non-emergency surgery strategies (including medical management, non-surgical procedures and elective surgery) for patients admitted to hospital with common acute gastrointestinal conditions.

Objectives

We aimed to evaluate the relative (1) clinical effectiveness of two strategies (i.e. emergency surgery vs. non-emergency surgery strategies) for five common acute conditions presenting as emergency admissions; (2) cost-effectiveness for five common acute conditions presenting as emergency admissions; and (3) clinical effectiveness and cost-effectiveness of the alternative strategies for specific patient subgroups.

Methods

The records of adults admitted as emergencies with acute appendicitis, cholelithiasis, diverticular disease, abdominal wall hernia or intestinal obstruction to 175 acute hospitals in England between 1 April 2010 and 31 December 2019 were extracted from Hospital Episode Statistics and linked to mortality data from the Office for National Statistics. Eligibility was determined using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnosis codes, which were agreed by clinical panel consensus. Patients having emergency surgery were identified from Office of Population Censuses and Surveys procedure codes. The study addressed the potential for unmeasured confounding with an instrumental variable design. The instrumental variable was each hospital’s propensity to use emergency surgery compared with non-emergency surgery strategies. The primary outcome was the ‘number of days alive and out of hospital’ at 90 days. We reported the relative effectiveness of the alternative strategies overall, and for prespecified subgroups (i.e. age, number of comorbidities and frailty level). The cost-effectiveness analyses used resource use and mortality from the linked data to derive estimates of incremental costs, quality-adjusted life-years and incremental net monetary benefits at 1 year.

Results

Cohort sizes were as follows: 268,144 admissions with appendicitis, 240,977 admissions with cholelithiasis, 138,869 admissions with diverticular disease, 106,432 admissions with a hernia and 133,073 admissions with an intestinal obstruction. Overall, at 1 year, the average number of days alive and out of hospitals at 90 days, costs and quality-adjusted life-years were similar following either strategy, after adjusting for confounding. For each of the five conditions, overall, the 95% confidence intervals (CIs) around the incremental net monetary benefit estimates all included zero. For patients with severe frailty, emergency surgery led to a reduced number of days alive and out of hospital and was not cost-effective compared with non-emergency surgery, with incremental net monetary benefit estimates of –£18,727 (95% CI –£23,900 to –£13,600) for appendicitis, –£7700 (95% CI –£13,000 to –£2370) for cholelithiasis, –£9230 (95% CI –£24,300 to £5860) for diverticular disease, –£16,600 (95% CI –£21,100 to –£12,000) for hernias and –£19,300 (95% CI –£25,600 to –£13,000) for intestinal obstructions. For patients who were ‘fit’, emergency surgery was relatively cost-effective, with estimated incremental net monetary benefit estimates of £5180 (95% CI £684 to £9680) for diverticular disease, £2040 (95% CI £996 to £3090) for hernias, £7850 (95% CI £5020 to £10,700) for intestinal obstructions, £369 (95% CI –£728 to £1460) for appendicitis and £718 (95% CI £294 to £1140) for cholelithiasis. Public and patient involvement translation workshop participants emphasised that these findings should be made widely available to inform future decisions about surgery.

Limitations

The instrumental variable approach did not eliminate the risk of confounding, and the acute hospital perspective excluded costs to other providers.

Conclusions

Neither strategy was more cost-effective overall. For patients with severe frailty, non-emergency surgery strategies were relatively cost-effective. For patients who were fit, emergency surgery was more cost-effective.

Future work

For patients with multiple long-term conditions, further research is required to assess the benefits and costs of emergency surgery.

The problem with dichotomizing quality improvement measures

The Anesthesia Quality Institute (AQI) promotes improvements in clinical care outcomes by managing data entered in the National Anesthesia Clinical Outcomes Registry (NACOR). Each case included in NACOR is classified as “performance met” or “performance not met” and expressed as a percentage for a length of time. The clarity associated with this binary classification is associated with limitations on data analysis and presentations that may not be optimal guides to evaluate the quality of care. High compliance benchmarks present another obstacle for evaluating quality. Traditional approaches for interpreting statistical process control (SPC) charts depend on data points above and below a center line, which may not provide adequate characterizations of a QI process with a low failure rate, or few possible data points below the center line. This article demonstrates the limitations associated with the use of binary datasets to evaluate the quality of care at an individual organization with QI measures, describes a method for characterizing binary data with continuous variables and presents a solution to analyze rare QI events using g charts.

PreciSSIon - a collaborative initiative to reduce surgical site infection after elective colorectal surgery

AIM

Surgical site infection (SSI) is common after colorectal surgery but most hospitals do not know their SSI rates. Approximately half of SSI occur after discharge and post-discharge surveillance is needed for accurate measurement. Peri-operative care bundles are known to reduce SSI. PreciSSion is a collaboration between seven hospitals in the West of England. The aims were to establish reliable SSI measurement after elective colorectal surgery using 30-day patient-reported outcome measures and to implement an evidence-based 4-point care bundle that had already demonstrated a reduction in SSI in a local hospital. The bundle included: 2% chlorhexidine skin preparation, a second dose of antibiotic after 4 hours, use of a dual-ring wound protector and antibacterial sutures for abdominal wall closure.

METHOD

30-day patient-reported SSI was undertaken using the Public Health England Questionnaire and response rates recorded. Baseline SSI was measured during November 2019 - May 2020 and continued after implementation of the care bundle until March 2021. Bundle compliance was also measured.

RESULTS

Average questionnaire response rate was 81%. Average compliance was 92%, 96%, 79% and 85% for each element of the bundle respectively. Baseline SSI was 8-30%. Six of seven hospitals reduced SSI and the regional average SSI rate almost halved from 18% (1447 patients) to 9.5% (1247 patients).

CONCLUSION

We have demonstrated that a care bundle developed in a single hospital can be adopted and spread and the reduction in SSI after elective colorectal surgery can be replicated in other hospitals and deliver results within 18 months.

Clinical Impact of a Quality Improvement Program Including Dedicated Emergency Radiology Personnel on Emergency Surgical Management: A Propensity Score-Matching Study

Objective

To investigate the clinical impact of a quality improvement program including dedicated emergency radiology personnel (QIP-DERP) on the management of emergency surgical patients in the emergency department (ED).

Materials and Methods

This retrospective study identified all adult patients (n = 3667) who underwent preoperative body CT, for which written radiology reports were generated, and who subsequently underwent non-elective surgery between 2007 and 2018 in the ED of a single urban academic tertiary medical institution. The study cohort was divided into periods before and after the initiation of QIP-DERP. We matched the control group patients (i.e., before QIP-DERP) to the QIP-DERP group patients using propensity score (PS), with a 1:2 matching ratio for the main analysis and a 1:1 ratio for sub-analyses separately for daytime (8:00 AM to 5:00 PM on weekdays) and after-hours. The primary outcome was timing of emergency surgery (TES), which was defined as the time from ED arrival to surgical intervention. The secondary outcomes included ED length of stay (LOS) and intensive care unit (ICU) admission rate.

Results

According to the PS-matched analysis, compared with the control group, QIP-DERP significantly decreased the median TES from 16.7 hours (interquartile range, 9.4–27.5 hours) to 11.6 hours (6.6–21.9 hours) (p < 0.001) and the ICU admission rate from 33.3% (205/616) to 23.9% (295/1232) (p < 0.001). During after-hours, the QIP-DERP significantly reduced median TES from 19.9 hours (12.5–30.1 hours) to 9.6 hours (5.7–19.1 hours) (p < 0.001), median ED LOS from 9.1 hours (5.6–16.5 hours) to 6.7 hours (4.9–11.3 hours) (p < 0.001), and ICU admission rate from 35.5% (108/304) to 22.0% (67/304) (p < 0.001).

Conclusion

QIP-DERP implementation improved the quality of emergency surgical management in the ED by reducing TES, ED LOS, and ICU admission rate, particularly during after-hours.

Outcomes of Acute Gallstone Disease During the COVID-19 Pandemic: Lessons Learnt

Introduction

This study aims to compare the patient demographics and management of acute manifestations of gallstone disease during the COVID-19 pandemic with an equivalent period in 2019 and assess the differences in recurrence patterns throughout the first and second waves of the pandemic in the UK.

Methods

A retrospective cohort study of all adult patients aged >16 years presenting to the emergency department at a large District General Hospital with symptoms related to gallstones. Data were obtained from electronic patient records. The primary outcomes were incidence and management of gallstone disease, while secondary outcomes studied included length of stay, readmission rate, and recurrence. Data were tabulated and analyzed using Excel (Microsoft, 2016 version). Chi-square and t-test were used as appropriate. One way ANOVA test was used to compare data of three groups.

Results

Fifty-one patients presented during the period of first-wave and 105 patients during the second wave as compared to 71 patients in the study period in 2019. The median age of patients during the first wave of COVID was significantly higher than pre-COVID in the second wave. During both the waves of the pandemic, there was no significant difference in patients presenting with cholecystitis compared with 2019 (47 and 94 in the first and second wave, respectively, versus 60 in 2019; p-value 0.39). There was no significant increase in the use of cholecystostomy, and the use of radiological investigations was comparable. There was no significant difference in recurrence and readmissions. The majority of the patients still await surgery.

Conclusion

During the pandemic, older patients with higher co-morbidity presented with acute gallstone disease. Conservative management was effective in the management of these patients.

Short and long term outcomes of laparoscopic fenestrating or reconstituting subtotal cholecystectomy versus laparoscopic total cholecystectomy in the management of acute cholecystitis

BACKGROUND

Strasberg proposed classifying subtotal cholecystectomy techniques into fenestrating (fSC) and reconstituting (rSC) subtypes. The aim of this study is to compare our outcomes of laparoscopic subtotal cholecystectomies of both subtypes against laparoscopic total cholecystectomy (TC) in difficult emergency laparoscopic cholecystectomies.

METHODS

Patients undergoing emergency laparoscopic cholecystectomy were identified over 2 years and all Nassar scale 3 and 4 cholecystectomies were included for analysis.

RESULTS

108 fSC and 24 rSC were compared against 317 TC. Patients undergoing fSC and rSC were older and more likely to be male. fSC (128 min) and rSC (141 min) recorded longer median operative times than TC (109). Post-operative ERCP was more common after rSC (16.7%). Patients undergoing fSC (2 days) and rSC (3.5 days) had longer post-operative stays. Bile leaks were more likely in fSC (9.3%) and rSC (8.3%) compared to TC (1.9%), Long term morbidity was higher in the rSC group (12.5% vs 10%). And these were solely due to gallbladder remnant complications.

CONCLUSION

Laparoscopic fSC and rSC techniques are associated with a higher rate of bile leaks and rSC has more long term morbidty as compared to TC.

Regional variations in Sweden over time regarding the surgical treatment of acute cholecystitis: a population-based register study

OBJECTIVE

To provide optimal health care for patients with acute cholecystitis in need of acute cholecystectomy, resource allocation has to be optimized. The aim of this study was to assess possible regional inequity regarding the treatment of acute cholecystitis and explore regional differences in the management of acute cholecystitis.

METHODS

Data were retrieved from the Swedish National Register for Gallstone Surgery and Endoscopic Retrograde CholangioPancreatography. Between January 2010 and December 2019, 22,985 patients who underwent cholecystectomy for acute cholecystitis and without prior history of acute cholecystitis were included in the study. The ratio of cholecystectomies with acute cholecystitis performed within two days of admission to hospital compared to population density was studied. Furthermore, the proportion of acute performed cholecystectomies within two days of admission in regions, with or without tertiary care centers, was also examined.

RESULTS

No correlation between population density and proportion of acute performed cholecystectomies was found. Regions without tertiary care centers had a higher proportion of acute cholecystectomies performed within two days (5-10%). The difference in the ratio of acute cholecystectomies within two days of admission was significant for all years investigated except 2010.

CONCLUSIONS

The presence of a tertiary referral center within the region had a greater influence than the population density on the chance of undergoing acute cholecystectomy for patients with acute cholecystitis. There are several potential explanations for this, one being an interference of the needs of patients requiring tertiary referral center care with the needs of patients in need of acute care surgery.

The Impact of Hospital Level of Care on the Management of Acute Cholecystitis: a Population-Based Study

BACKGROUND

The organization of healthcare could have an impact on the outcome of patients treated for acute cholecystitis (AC). The aim of this study was to analyze the way in which patients with AC are managed relative to the level of care by the treating hospital.

METHODS

Data were collected from the Swedish Register for Gallstone Surgery and ERCP (GallRiks). Cholecystectomies between 2010 and 2019 were included. The inclusion criterion was acute cholecystectomy in patients with AC operated at either tertiary referral centers (TRCs) or regional hospitals.

RESULTS

A total of 24,194 cholecystectomies with AC met the inclusion criterion. The time between admission and acute surgery was significantly elongated at TRCs compared with regional hospitals (2.2 ± 1.7 days vs. 1.6 ± 1.4 days, mean ± SD; p < 0.0001). Patients with a history of AC were more frequent at TRC (10.1% vs. 8.9%, p < 0.0056) and had a higher adverse event rate compared with those at regional hospitals (OR 1.61; CI 1.40-1.84, p < 0.0001). Surprisingly, an increased number of hospital beds correlated slightly with an increased number of days between admission and surgery (R² = 0.132; p = 0.0075).

CONCLUSION

Compared with regional hospitals, patients with AC had to wait longer at TRCs before surgery. A history of AC significantly increased the risk of adverse events. These findings indicate that logistic and organizational aspects of hospital care may affect the management of patients with AC. However, whether these findings can be generalized to healthcare organizations outside Sweden requires further investigation.

Variation in the rates of emergency surgery amongst emergency admissions to hospital for common acute conditions

Background

This paper assesses variation in rates of emergency surgery (ES) amongst emergency admissions to hospital in patients with acute appendicitis, cholelithiasis, diverticular disease, abdominal wall hernia, and intestinal obstruction.

Methods

Records of emergency admissions between 1 April 2010 and 31 December 2019 for the five conditions were extracted from Hospital Episode Statistics for 136 acute National Health Service (NHS) trusts in England. Patients who had ES were identified using Office of Population Censuses and Surveys (OPCS) procedure codes, selected by consensus of a clinical panel. The differences in ES rates according to patient characteristics, and unexplained variations across NHS trusts were estimated by multilevel logistic regression, adjusting for year of emergency admission, age, sex, ethnicity, diagnostic subcategories, index of multiple deprivation, number of co-morbidities, and frailty.

Results

The cohort sizes ranged from 107 325 (hernia) to 268 253 (appendicitis) patients, and the proportion of patients who received ES from 11.0 per cent (diverticular disease) to 92.3 per cent (appendicitis). Older patients were generally less likely to receive ES, with adjusted odds ratios (ORs) of ES for those aged 75–79 versus those aged 45–49 years: 0.34 (appendicitis), 0.49 (cholelithiasis), 0.87 (hernia), and 0.91 (intestinal obstruction). Patients with diverticular disease aged 75–79 were more likely to receive ES than those aged 45–49 (OR 1.40). Variation in ES rates across NHS trusts remained after case mix adjustment and was greatest for cholelithiasis (trust median 18 per cent, 10th to 90th centile 7–35 per cent).

Conclusion

For patients presenting as emergency hospital admissions with common acute conditions, variation in ES rates between NHS trusts remained after adjustment for demographic and clinical characteristics. Age was strongly associated with the likelihood of ES receipt for some procedures.

Is there seasonal variation in gallstone related admissions in England?

BACKGROUND

Gallstone related pathology (GRP) accounts for a significant proportion of general surgery admissions. The aim of this study is to investigate if seasonal variation for GRP admissions exist in England allowing improved resource allocation and planning.

METHODS

This multicentre retrospective cohort study included only emergency adult (≥18 years old) admissions to acute secondary care with ICD-10 codes associated with gallstones between 01/01/2010 to 31/12/2019 in England using Hospital Episode Statistics data. Seasons were defined according to United Kingdom Met Office.

RESULTS

A total of 396 879 GRP related admissions were recorded during the specified period, accounting for 1.44% of all emergency admissions. Our study suggests a significant seasonal peak in Summer (n = 102 620) based cumulative admissions per season and a linear regression model (p < 0.001), followed by Autumn (n = 102 267), then Spring (n = 97 807) and finally Winter (n = 94 185). Spectral analysis confirmed there is seasonality in the emergency GRP admissions every 12 months. A forecasting model was shown to be reliable; all observed admissions for 2019 were within the 95% prediction intervals for each month for the proportion of emergency GRP admissions.

CONCLUSION

Resource allocation towards the Summer months to target seasonal peaks in GRP should be considered.

Evaluating quality in clinical care

Defining and maintaining quality is essential to surgical practice. It is only through structured approaches to assessing outcomes that we can ensure that optimal care is delivered. This article will define quality in healthcare and discuss assessment models with reference to pertinent surgical literature. National initiatives are discussed with a critical appraisal of their role and effectiveness. We discuss the aim of quality improvement initiatives and comment on reporting of outcomes. The difficult question of how to maintain quality during a crisis, such as an infectious disease pandemic, is addressed.

Understanding the influences on successful quality improvement in emergency general surgery: learning from the RCS Chole-QuIC project

BACKGROUND

Acute gallstone disease is the highest volume Emergency General Surgical presentation in the UK. Recent data indicate wide variations in the quality of care provided across the country, with national guidance for care delivery not implemented in most UK hospitals. Against this backdrop, the Royal College of Surgeons of England set up a 13-hospital quality improvement collaborative (Chole-QuIC) to support clinical teams to reduce time to surgery for patients with acute gallstone disease requiring emergency cholecystectomy.

METHODS

Prospective, mixed-methods process evaluation to answer the following: (1) how was the collaborative delivered by the faculty and received, understood and enacted by the participants; (2) what influenced teams' ability to improve care for patients requiring emergency cholecystectomy? We collected and analysed a range of data including field notes, ethnographic observations of meetings, and project documentation. Analysis was based on the framework approach, informed by Normalisation Process Theory, and involved the creation of comparative case studies based on hospital performance during the project.

RESULTS

Chole-QuIC was delivered as planned and was well received and understood by participants. Four hospitals were identified as highly successful, based upon a substantial increase in the number of patients having surgery in line with national guidance. Conversely, four hospitals were identified as challenged, achieving no significant improvement. The comparative analysis indicate that six inter-related influences appeared most associated with improvement: (1) achieving clarity of purpose amongst site leads and key stakeholders; (2) capacity to lead and effective project support; (3) ideas to action; (4) learning from own and others' experience; (5) creating additional capacity to do emergency cholecystectomies; and (6) coordinating/managing the patient pathway.

CONCLUSION

Collaborative-based quality improvement is a viable strategy for emergency surgery but success requires the deployment of effective clinical strategies in conjunction with improvement strategies. In particular, achieving clarity of purpose about proposed changes amongst key stakeholders was a vital precursor to improvement, enabling the creation of additional surgical capacity and new pathways to be implemented effectively. Protected time, testing ideas, and the ability to learn quickly from data and experience were associated with greater impact within this cohort.
