Emergency urolithiasis management at a national level: exploring the need for a care pathway.

BACKGROUND: Urolithiasis is a common urological presentation1. A total of 25-49 million people in Europe live with symptomatic stone disease, with the incidence increasing1. AIMS: To examine length of stay (LOS) and transfer patterns for patients presenting with urolithiasis to Irish Model 2/3 hospitals without a specialist urology service, compared with those who present to a model 4 hospital with an on-site urology service. METHODS: Using the National Quality Assurance & Improvement System (NQAIS), we assessed patients presenting with urolithiasis, nationally from January 2016 to December 2019. RESULTS: During the study period, there were 11,856 emergency presentations with urolithiasis. A total of 6510 (54.9%) presented to model 4 hospitals, while 5346 (45.1%) presented to model 2/3 hospitals. A total of 874 (16.35%) patients required transfer from model 2/3 hospital to a model 4 hospital for further management. Those transferred from model 2/3 hospitals spent a mean of 3.68 days awaiting transfer and had a mean LOS of 3.88 days in the model 4 hospital. A total of 7.56 days compared with a mean LOS of 2.9 days for those presenting directly to a model 4 hospital. CONCLUSION: At a national level in Ireland, many patients with urolithiasis present to hospitals that are unable to cater for their needs. Patients presenting with urolithiasis to model 2/3 hospitals have significantly longer LOS compared with patients who present directly to a model 4 hospital. A formal 'stone pathway' is required to provide timely care for these patients2-such a pathway would provide better patient care and result in improved bed utilisation.

Does clinical validation and the implementation of new models of outpatient service delivery have the potential to reduce waiting lists? A pilot study in Letterkenny University Hospital.

INTRODUCTION: The traditional outpatient paradigm of seeing patients prior to diagnostic tests and treatment is unsustainable without additional funding. New models of service delivery such as "one-stop clinics", direct access to diagnostics and advanced nurse practitioner (ANP)-led clinics have the potential to improve the efficiency of existing services. METHODS: To determine the most effective changes to improve service provision, the reasons for encounter (RFE) to a urology clinic were assessed using the International Classification Primary Care. To test these changes, a clinical validation process was performed on existing waiting patients waiting ≥ 15 months. Direct access to diagnostics and an ANP-led clinic were introduced. The impact of this validation process was measured prospectively using independently-collated National Treatment Purchase Fund waiting list data. RESULTS: From January to December 2017, 1114 new patients were referred. The 3 most frequent RFEs were haematuria, urinary frequency/urgency and cystitis and accounted for 48% of referrals overall. A new outpatient pathway, combining direct access to diagnostics and an ANP-led clinic, was implemented on 508 existing patients waiting ≥ 15 months. The validation process resulted in referral directly to a consultant-led clinic in 36%, to an ANP-led clinic in 12%, direct access to diagnostics in 38% and removal in 13%. This change was implemented in July 2017 and there was a 76% reduction in the number of patients waiting ≥ 12 months by December 2017. CONCLUSION: New models of outpatient service delivery have the potential to reduce existing waiting lists and could be implemented in other Irish hospital groups.

Should all paediatric appendicectomies be performed in a specialist or high-volume setting?

INTRODUCTION: Acute appendicitis is a common surgical emergency in children. The majority of appendicectomies in children are performed by general surgeons, rather than specialist paediatric surgeons. AIM: To assess the impact of hospital specialization, hospital volume, and surgeon volume on outcomes for children undergoing appendicectomy in Ireland. METHODS: NQAIS (National Quality Assurance and Improvement System) data for all appendicectomies performed on children in Ireland between January 2014 and November 2017 was examined. Hospitals were categorized as specialist paediatric centres (SPCs), high-volume general (HVGHs), moderate-volume general (MVGHs), or low-volume general (LVGHs) by annual case volume. Similarly, surgeons were categorized as high-volume (HVSs), moderate-volume (MVSs), or low-volume (LVSs) by annual volume. Data relating to patient demographics, type of surgery (open/laparoscopic/laparoscopic converted to open), length of stay (LOS), mortality, admission to critical care, and readmission rates were collected and analysed. RESULTS: About 9593 appendicectomies were performed in 21 hospitals by 134 surgeons. Patients in SPCs had lowest overall rates of laparoscopic surgery (48% v 66% (HVGHs) v 70% (MVGHs) v 57%(LVGHs), p < 0.001). In SPCs 30-day readmission rates were lower for younger children (5.3% for 5-8-year olds v 6.7% (HVGHs) v 7.3%(MVGHs) v 10.5% (LVGHs), p = 0.023). HVSs performed more laparoscopic appendicectomies on younger patients (0-4 years: 40% v 6% (MVSs) v 17%(LVSs), p < 0.001) but performed the least on older children (13-16 years: 76% v 82%(MVSs) v 82%(LVSs), p < 0.001). CONCLUSION: Children younger than 8 years undergoing appendicectomy in HVGHs or SPCs, or by HVSs, have marginally better outcomes. In older children, marginally shorter in-hospital stays and higher laparoscopic rates are seen in those looked after outside of high-volume or specialist units. Our results show that nonspecialist centres provide an essential, and safe, service to paediatric patients with acute appendicitis.

Patient satisfaction reporting-a cohort study comparing reporting of patient satisfaction pre- and post-discharge from hospital.

BACKGROUND: Patients' satisfaction reporting is important for assessing the quality of care in surgical practice. Post-discharge questionnaire reporting is considered best practice; however, the logistics of this method remains problematic. AIMS: To examine patient satisfaction response rates prior to and following discharge from the hospital in a general surgery department. METHODS: Two patient groups were examined: group 1-questionnaires were completed by patients prior to discharge; and group 2-questionnaires were posted to patients following discharge and were advised to return the questionnaire in a given time frame. The questionnaire design was based on the WHO strategy on measuring responsiveness guidelines tailored to a population of surgical patients. RESULTS: Four hundred and fifty patients were examined [group 1 (N = 150); group 2 (N = 300)]). Results from pre- and post-discharge questionnaires were similar in almost all parameters. The response rate dropped significantly in group 2, and the cost was also significantly higher. CONCLUSIONS: There were no significant differences in reporting between pre- and post-discharge questionnaire responses. As pre-discharge reporting is more efficient, less costly and has a higher response rate, this should be considered the preferred practice in patient satisfaction assessments.

Over-admission and over-treatment of patients with cellulitis: a 5-year audit against international guidelines.

BACKGROUND/AIMS: Application of evidence-based guidelines in the management of cellulitis is poorly studied in Ireland and it is observed that current admission and prescription practices in this country vary widely from internationally accepted standards of care. We aimed to examine the management of cellulitis with regard to hospital admission and initial antibiotic therapy. METHODS: A retrospective audit of patients admitted with cellulitis from 2013 to 2017 in an Irish district general hospital. Exclusion criteria included specialist regions of the body and surgical site infections. Appropriateness of admission and management was compared against international guidelines (Clinical Research Efficiency Support Team (CREST) and Infectious Disease Society of America (IDSA)). RESULTS: Five hundred twenty emergency admissions with cellulitis were analysed. Thirty-five percent (n = 182) were deemed inappropriate admissions compared with CREST and IDSA guidelines, with an estimated cost of €152,203 per annum. Ninety-six percent (n = 501) of patients with cellulitis were treated with a combination of flucloxacillin and benzylpenicillin, despite level 1 evidence showing combination therapy to provide no benefit over appropriate monotherapy. CONCLUSIONS: There is a significant discrepancy between current clinical practice and international guidelines for the management of cellulitis in Ireland; local guidelines are not in keeping with newer evidence and there is a lack of national guidelines for this common condition. Closer adherence to international guidelines would significantly reduce costs by reducing unnecessary admissions and initial monotherapy would improve antibiotic stewardship. This study shows a clear need for local institutions to re-examine antibiotic guidelines to ensure the HSE provides effective evidence-based treatment in the correct setting.

Risk factors for surgical site infection following colorectal resection: a multi-institutional study.

INTRODUCTION: Surgical site infection (SSI) is an infection occurring in an incisional wound within 30 days of surgery and significantly affects patients undergoing colorectal surgery. This study examined a multi-institutional dataset to determine risk factors for SSI following colorectal resection. METHODS: Data on 386 patients who underwent colorectal resection in three institutions were accrued. Patients were identified using a prospective SSI database and hospital records. Data are presented as median (interquartile range), and logistic regression analysis was used to identify risk factors. RESULTS: Patients (21.5%) developed a postoperative SSI. The median time to the development of SSI was 7 days (5-10). Of all infections, 67.5% were superficial, 22.9% were deep and 9.6% were organ space. In univariate analysis, an ASA grade of II (RR 0.6, CI 0.3-0.9, P = 0.019), having an elective procedure (RR 0.4, CI 0.2-0.6, P < 0.001), using a laparoscopic approach (RR 0.5, CI 0.3-0.9, P = 0.019), having a daytime procedure (RR 0.3, CI 0.1-0.7, P = 0.006) and having a clean/contaminated wound (RR 0.4, CI 0.2-0.7, P = 0.001) were associated with reduced risk of SSI. In multivariate analysis, an ASA grade of IV (RR 3.9, CI 1.1-13.7, P = 0.034), a procedure duration over 3 h (RR 4.3, CI 2.3-8.2, P < 0.001) and undergoing a panproctocolectomy (RR 6.5, CI 1.0-40.9, P = 0.044) were independent risk factors for SSI. Those who developed an SSI had a longer duration of inpatient stay (22 days [16-31] vs 15 days [10-26], P < 0.001). CONCLUSIONS: Patients who develop an SSI have a longer duration of inpatient stay. Independent risk factors for SSI following colorectal resection include being ASA grade IV, having a procedure duration over 3 h, and undergoing a panproctocolectomy.

Preoperative hypoalbuminemia is an independent risk factor for the development of surgical site infection following gastrointestinal surgery: a multi-institutional study.

BACKGROUND: Surgical site infection (SSI) is an infection occurring in an incisional wound within 30 days of surgery and significantly effects patient recovery and hospital resources. OBJECTIVE: This study sought to determine the relationship between preoperative serum albumin and SSI. METHODS: A study of 524 patients who underwent gastrointestinal surgery in 4 institutions was performed. Patients were identified using a prospective SSI database and hospital records. Serum albumin was determined preoperatively in all patients. Hypoalbuminemia was defined as albumin <30 mg/dL. Data are presented as median (interquartile range) and a difference between groups was examined using Mann-Whitney U and Fisher exact test and multiple logistic regression analysis. RESULTS: A total of 105 patients developed a SSI (20%). The median time to the development of SSI was 7 (5-10) days. Having an emergency procedure (P = 0.003), having a procedure over 3 hours in duration (P = 0.047), being American Society of Anaesthetics grade 3 (P = 0.03) and not receiving preoperative antibiotics (P = 0.007) were associated with SSI while having a laparoscopic procedure reduced the likelihood of SSI (P = 0.004). Patients who developed a SSI had a lower preoperative serum albumin (30 [25-34.5] vs. 36 [32-39], P < 0.001). On multivariate analysis, hypoalbuminemia was an independent risk factor for SSI development (relative risk, RR = 5.68, 95% confidence interval: 3.45-9.35, P < 0.001). Albumin <30 mg/dL was associated with an increased rate of deep versus superficial SSI (P = 0.002). The duration of inpatient stay was negatively correlated with preoperative albumin (R = -0.319, P < 0.001). CONCLUSIONS: Hypoalbuminemia is an independent risk factor for the development of SSI following gastrointestinal surgery and is associated with deeper SSI and prolonged inpatient stay.

Emergency first presentation of colorectal cancer predicts significantly poorer outcomes: a review of 356 consecutive Irish patients.

PURPOSE: Colorectal cancer commonly presents first as an emergency and is likely to be complicated by bowel obstruction/perforation requiring more difficult procedures, with poorer outcomes. Analysis of all of the procedures performed on patients diagnosed in Wexford General Hospital, Ireland, during the period 2000 to 2006 was carried out to validate this hypothesis in our western European population. METHODS: Retrospective analysis of a prospectively maintained database of patient demographics, diagnosis, procedures, and mode of presentation (elective, emergency) was undertaken. RESULTS: A total of 356 patients with colorectal cancer underwent 498 procedures during the years 2000 to 2006. Eighty-four emergency endoscopies and 100 emergency bowel resections were performed. Obstructive lesions were more likely to require emergency resection (P < 0.001). Median survival time for patients treated electively was 82 months vs. 59 months for patients treated on an emergency basis. CONCLUSIONS: Of all colonic resections, 34 percent were carried out as emergencies and were significantly more likely to be complicated by obstruction or perforation (P < 0.001). Emergency resections were associated with a significantly poorer perioperative mortality and five-year survival rate (P < 0.001). Forty-one percent of colorectal cancers diagnosed at endoscopy were first seen emergently. These data raise concerns regarding public awareness of colorectal cancer and resource allocation and reemphasize the need for a national colorectal screening program.
