Abstract Aim There is significant variation in management of acute appendicitis across the UK. Despite advancements in imaging modalities, acute appendicitis is still a clinical diagnosis. The primary aim of this study was to determine the negative appendectomy rate (NAR) and secondary aim was to look for the imaging results and hospital readmission rate in case of a normal appendix. Method It is a retrospective analysis of all the patients admitted with a suspicion of acute appendicitis from Jan 2018 to April 2019. For data collection hospital medical record was used. Information about patient demographic details, blood results, outcome, operative findings, and histology of appendix if removed, was collected. For Patients having negative appendectomy, hospital admission rate was calculated. Results Total 517 patients were admitted with suspected acute appendicitis and only 45.6% (n = 236) patients underwent surgery. Females=52.1%, Males 47.9%. Mean age was 31 years. NAR was 10.6% (n = 25). (Females= 9.3%, Males=1.3%), 8.4% female patients were below 35 years of age. Patients were divided into 3 groups (Normal appendix NA, Uncomplicated appendicitis UA, complicated appendicitis CA). There was a statistically significant difference in inflammatory markers between the groups. In NA group 17/25 patients underwent prior imaging and imaging suggested acute appendicitis in 7/17 patients. Post NA hospital readmission rate was 20%, all of them were females, and gynecology opinion was sought in all of them. Conclusions The negative appendectomy rate is at 10.6%, comparable to national database. It is more common in young females due to a range of differential diagnoses.

Abstract Aims Appendicitis remains the most common acute surgical condition.  No standard guidelines for the use of imaging studies, and there is a discrepancy between the published data regarding accuracy of these modalities and our practical findings. Yet the growing number of USS reported as “appendix not visualized” has led us to rethink about the value of USS in acute appendicitis.  Methods A retrospective single centre study for all females (15-45 years) underwent emergency appendectomy for suspected acute appendicitis. Analysis of preoperative clinical, radiographic and postoperative histopathological data was done. Results 632 cases analysed over 18months, out of those 238 (37%) were females (15-45 years). USS was done in 129(54%) cases. 25(10.5) cases had both USS and CTAP. 32(13%) cases had only CTAP. The mean rate of appendix visualization in the USS was 30%(71cases) two thirds reported by radiologist versus one third by sonographers. Our negative appendectomy rate dropped from 25 to 15% after a positive scan.  Conclusions Traditional preference for ultrasound in the UK compared to CTAP in young population is mostly due to the potential hazards of irradiation, but USS commonly does not visualise the appendix in our practice (70%), and has low sensitivity and specificity for appendicitis.  However, following a positive USS, NAR dropped to 15%. Radiologists had a higher visualization rate of appendix compared to sonographers. Commitment to improve the performance of ultrasonography by allocating adequately timed sessions to the most experienced radiologists and increasing the use of low dose CT scans are possible solutions.

Negative Appendectomy Rate

(1) Background: Diagnosis of acute appendicitis (AA) remains challenging; either computed tomography (CT) is universally used or negative appendectomy rates of up to 30% are reported. Transabdominal ultrasound (TUS) as the first-choice imaging modality might be useful in adult patients to reduce the need for CT scans while maintaining low negative appendectomy (NA) rates. The aim of this study was to report the results of the conditional CT strategy for the diagnosis of acute appendicitis. (2) Methods: All patients suspected of acute appendicitis were prospectively registered from 1 January 2016 to 31 December 2018. Data on their clinical, radiological and surgical outcomes are presented. (3) Results: A total of 1855 patients were enrolled in our study: 1206 (65.0%) were women, 649 (35.0%) were men, and the median age was 34 years (IQR, 24.5–51). TUS was performed in 1851 (99.8%) patients, and CT in 463 (25.0%) patients. Appendices were not visualized on TUS in 1320 patients (71.3%). Furthermore, 172 (37.1%) of 463 CTs were diagnosed with AA, 42 (9.1%) CTs revealed alternative emergency diagnosis and 249 (53.8%) CTs were normal. Overall, 519 (28.0%) patients were diagnosed with AA: 464 appendectomies and 27 diagnostic laparoscopies were performed. The NA rate was 4.2%. The sensitivity and specificity for TUS and CT are as follows: 71.4% and 96.2%; 93.8% and 93.6%. (4) Conclusion: A conditional CT strategy is effective in reducing NA rates and avoids unnecessary CT in a large proportion of patients. Observation and repeated TUS might be useful in unclear cases.

BACKGROUND AND OBJECTIVES: Hospital readmission rate helps to highlight the effectiveness of post- discharge care. There remains a paucity of plausible age based categorization especially for ages below one year for hospital readmission rates. METHODS: Data from 2017 Healthcare cost and utilization project National readmissions database was analyzed for ages 0-18 years. Logistic regression analysis was performed to identify predictors for unplanned early readmissions. RESULTS: We identified 5,529,389 inpatient pediatric encounters which were further divided into age group cohorts. The overall rate of readmissions was identified at 3.2%. Beyond infancy, the readmission rate was found to be 6.7%. Across all age groups, the major predictors of unplanned readmission were cancers, diseases affecting transplant recipients and sickle cell patients. It was determined that reflux, milk protein allergy, hepatitis and inflammatory bowel diseases were significant comorbidities leading to readmission. Anxiety, depression and suicidal ideation depicted higher readmission rates in those older than 13 years. Across ages 1-4 yrs, dehydration, asthma and bronchitis were negative predictors of unplanned readmission. CONCLUSIONS: Thirty-day unplanned readmissions remain a problem leading to billions of tax-payer-dollars lost per annum. Effective strategies for mandatory outpatient follow-up may help the financial aspect of care while also enhancing the quality of care.

Discharge Against Medical Advice

A retrospective case note study explored readmissions to an acute psychiatric in-patient unit within six months of discharge. The study aimed to calculate a hospital readmission rate, to investigate the timing of readmissions, and to identify risk factors associated with readmission. The readmission rate was 27% with the majority of readmissions occurring within three months after discharge, suggesting the need for investigation of such early readmissions. The three factors found to predict readmission were: discharge against medical advice, number of previous admissions, and living alone or with family rather than in care. Implications for hospital service planning are considered.

Pathology Reports

The highest degrees of accuracy have been demonstrated for CT scans using rectal contrast in diagnosing appendicitis. However, the administration of rectal contrast is associated with patient discomfort and rarely, rectosigmoid perforation (0.04%). Additionally, the commonly accepted negative appendectomy rate is around 16 per cent. We performed a retrospective review of radiology, operative, and pathology reports of consecutive patients undergoing appendectomy or CT examination for appendicitis during 2006. CT scans were performed without rectal contrast. The accuracy of each type of inpatient CT examination and negative appendectomy rates were determined. Two hundred and thirty-eight patients underwent appendectomy. One hundred and thirty-four appendectomy patients (56%) received a preoperative CT scan. The negative appendectomy rates were 6.3 per cent overall, 8.7 per cent without CT examination and 4.5 per cent with CT (P = 0.3). Two hundred and forty-five inpatient CT scans were performed for suspected appendicitis with a sensitivity of 90 per cent, specificity of 98 per cent, accuracy of 94 per cent, positive predictive value of 98 per cent, and negative predictive value of 91 per cent. CT scanning without rectal contrast is effective for the diagnosis of acute appendicitis making rectal contrast, with its attendant morbidity, unnecessary. The previously acceptable published negative appendectomy rate is higher than that found in current surgical practice likely due to preoperative CT scanning.

e18513 Background: FN is an anticipated complication of consolidation with HiDAC for AML, though precise descriptions of incidence, type, and severity of infection leading to FN are lacking. Since AML patients (pts) with FN after HiDAC are routinely readmitted to the hospital, there is a likely impact on measures of quality and value in this population. Methods: Our primary aim was to define the rate of FN inpatient readmissions among all HiDAC cycles. Secondary aims included: estimating rates of all-cause readmissions, clinical (e.g., probable pneumonia per imaging) and microbiologically-documented infections, and identify pts-specific risk factors associated with readmission. Readmission per patient were modeled using Poisson regression, with means proportional to total cycles exposed, and logistic regression for the probability of FN per treatment cycle. Results: We identified 150 AML pts ≥ 18 years of age, who received at least one cycle of HiDAC consolidation (1000-3000 mg/m2 for six doses) in 2009-2016. The median age was 50 (range 19-69); 55% were female and 45% were male. For 417 HiDAC cycles analyzed (87% at 3000 mg/m2), all pts received flouroquinalone prophylaxis and the overall readmission rate was 49% (203/417), of which 86% (174/203) were for FN. Median time to FN hospital admission was 18 days (range 10-22) from the start of HiDAC. Of the 174 FN readmissions, 60% had documented infections. Of these infections, 35% were bacteremia, 29% other bacterial, 24% fungal, 6% sepsis, and 6% viral. Females had higher FN readmission rates (RR 1.7 (1.3, 2.4) p = 0.007), as did pts with higher BMI (RR 1.06 (1.01, 1.09) p = 0.005), while age and HiDAC dose were not associated with readmission. Only 34% of all readmissions were in the absence of a documented infection. Conclusions: The majority of FN readmissions were associated with clinical or microbiologically documented infections and are not avoidable. Females and pts with higher BMI were more likely to be readmitted. Readmission of AML pts following HiDAC is expected, and therefore, should be excluded from measures of value and quality.

Background: Acute appendicitis is one of the most frequent abdominal emergencies and appendectomy subsequently the most common emergency operation performed all over the world. The aim of the study is to evaluate the reliability of Clinical Diagnosis for diagnosis of acute appendicitis and correlate it with the gold standard and absolute diagnostic modality, histopathology.Methods: This is a prospective study carried out in 150 patients who were admitted under department of surgery, AFMC Pune, Maharashtra from 1st July 2014 to 31st June 2016 for a clinical diagnosis of acute appendicitis.Results: In our study overall negative appendectomy rate was 18.7% (12.37% in male and 30.19% in female). Hence in the overall females had more negative appendectomy rate compared to males. In our series a score of >7 using Alvarado system had a total sensitivity of 72.95%. While sensitivity increases to 99.18% when score of >5 used as cut-off.Conclusions:Alvarado scoring system is beneficial in decreasing negative appendectomy rate and thus reduces complication rates. It is effective in the diagnosis of acute appendicitis in both men and females but some other diagnostic modality may be necessary to ascertain the diagnosis in females along with the clinical scoring system to rule out other pelvic pathology and to reduce negative appendectomy rate in females.

Negative Appendectomy Rate

Background: Acute appendicitis (AA) has a lifetime risk of 8.3% with a consequent 23% lifetime risk of emergency appendectomy. In atypical presentation, making a clinical diagnosis is difficult, leading to a high perforation rate (PR) or misdiagnoses and high negativeappendectomy rates (NAR). This study aimed to establish NAR and explore the associated factors and possible attainable solutions to reduce it in urban referral hospitals in Tanzania. Methods: This was a crosssectional study with 91 consecutive patients, aged 10 years and older undergoing appendectomy for  suspected AA with histological evaluation of specimens. The study was powered to detect the NAR at 95% confidence level and 80% power. Results: The histological NAR was 38.5% and the perforation rate was 25.3%. The Alvarado score (AS) was rarely applied (6%), despite ademonstrated ability in this study to decrease the NAR by half. Females were four times more likely to undergo negative appendectomy than males. Conclusion: The NAR is clinically significant as about two out of every five patients undergoing emergency appendectomy for suspected AA do not require the procedure. The AS is underutilized despite a demonstrated ability to decrease the NAR. We recommend that the AS be incorporated in the management of patients with suspected appendicitis.
