Use of a Clinical Audit System in Implementing Surviving Sepsis Campaign Guidelines in Patients With Peritonitis.

Background Sepsis is the predominant cause of morbidity and mortality in patients with peritonitis. "Surviving Sepsis Campaign" (SSC) is an international effort in reducing mortality based on evidence-based guidelines. This study aims to assess the impact of audit-based feedback in a Plan-Do-Study-Act (PDSA) format on improving the implementation of the SSC guidelines in patients with generalized peritonitis at our center. Methods This prospective observational study was conducted in four audit cycles in PDSA format. Multi-departmental inputs were taken to suggest modifications in practice. A questionnaire-based analysis of reasons for non-compliance was performed to find out the opinions and reasons for non-compliance. Morbidity, mortality, and the length of ICU and hospital stay among these patients were also analyzed. Results Baseline compliance with intravenous (IV) bolus administration, central venous pressure (CVP)-guided fluids, and inotropes support when indicated were 100%. Over the course of the three audit cycles, statistically significant improvement in compliance was noted for obtaining blood cultures before antibiotics, antibiotic administration within three hours of presentation, and serum lactate measurement. Overall bundle compliance improved from 9.2% to 64.7% by the end of audit cycle III. Conclusions This study demonstrates that audit-based feedback is a dependable means of improving compliance with SSC guidelines. It brings about improvement by educating users, modifying their behavior through feedback, and enhances process improvement by identifying and correcting systemic deficiencies in the organization.

Hereditary Medullary Thyroid Carcinoma: Genotype, Phenotype and Outcomes in a North Indian Cohort.

BACKGROUND: Aggressiveness of hereditary medullary thyroid carcinoma (hMTC) has been conventionally described to correlate with American Thyroid Association (ATA) risk groups based on RET mutations. Recent evidence increasingly contradicts this notion. We studied the RET genotype and its correlation with disease phenotype and survival outcomes in a cohort of hMTC patients. METHODS: In a retrospective cohort of 55 hMTC patients from 23 families treated at a north Indian tertiary care institute over 15-years, RET genotype was correlated with disease phenotype (clinical, biochemical, and pathological attributes) and outcomes in terms of biochemical cure (normalization of serum calcitonin), structural cure, overall survival (OS) and disease specific survival (DSS). RESULTS: Forty-nine patients had Multiple Endocrine Neoplasia (MEN)-type 2A syndrome, 02 had MEN-2B, and 4 had familial MTC. Two patients belonged to highest ATA risk, 41 to high-risk, and 12 to moderate risk categories. Age of the patients or stage of disease at presentation did not differ significantly between the ATA risk groups. Though the baseline serum calcitonin was significantly higher in highest risk category, the biochemical cure rates were not significantly different. At a median follow up of 48 months (Inter-quartile range 18-84, range 12-192) structural cure rates in ATA moderate and high risk groups were significantly higher than highest risk group (p = 0.04). No significant difference in OS between the three ATA groups of hMTC among the patients who underwent surgical treatment was observed (p = 0.098). CONCLUSIONS: The ATA moderate and high risk groups have better structural cure rates compared to ATA highest risk group. The biochemical cure and overall survival rates did not significantly differ between ATA risk-groups, and were impacted by the disease stage at presentation. The current ATA risk-groups do not reliably predict the outcomes in terms of biochemical cure and survival in hMTC patients.

Low-cost Fluorescein as an Alternative to Radio-colloid for Sentinel Lymph Node Biopsy-a Prospective Validation Study in Early Breast Cancer.

BACKGROUND: Sentinel lymph node biopsy (SLNB) using radio-pharmaceutical (RP) and a blue dye is gold standard for axillary staging in clinically node-negative early breast cancer. High costs and limited availability of RP and/or gamma probe are major deterrents in performing SLNB in developing countries. Fluorescence-guided SLNB can obviate the need for RP and gamma probe. Fluorescein is an inexpensive fluorescent lymphatic tracer. In this study, we compared SLN identification rate (SLN-IR) and false negative rates (FNR) of fluorescein-guided SLNB and radio-guided SLNB using 99mTc-Sulfur-colloid, in isolation, or in combination with methylene blue dye (MBD). METHODS: Sixty-five cN0 early and large operable breast cancer patients underwent validation SLNB using fluorescein (and blue LED light), 99mTc-Sulfur-colloid (and gamma probe) and MBD. Inj Fluorescein 4% was injected, 1 ml each peri-tumoral and sub-areolar five minutes before axillary incision. Axillary dissection was performed irrespective of SLNB histology. The SLN-IR and FNR with various tracers and their combinations were compared. RESULTS: The mean number of SLNs identified was 3.5 ± 1.8 (range 1-6). The SLN-IR using RP alone was 94%, fluorescein alone was 92%, and MBD alone was 82%. The SLN-IR using fluorescein plus MBD combination was 95.4%, compared to 97% using MBD plus RP combination. FNR was 6.3% using fluorescein plus MBD, as well as RP plus MBD combinations. CONCLUSIONS: SLN-IR of > 90% and SLN-FNR of < 10% using fluorescein plus MBD combination are in acceptable range, and are comparable to that of RP plus MBD combination. Fluorescein can replace RP for performing SLNB, in combination with MBD.

Genetic Profile of Indian Pheochromocytoma and Paraganglioma Patients - A Single Institutional Study.

BACKGROUND AND AIMS: Pheochromocytomas (PCCs) and Paragangliomas (PGL) are rare catecholamine producing tumors that may present in sporadic or familial settings. Despite vast strides in understanding of PCC/PGL genetics in the last two decades, there is a dearth of information from India. The aim here is to study the prevalence of genetic mutations in Indian PCC/PGL patients. SETTINGS AND DESIGN: Tertiary care academic hospital; prospective study. METHODS: 50 histopathologically diagnosed PCC/PGL patients formed the study group. Clinical, biochemical, pathological attributes and outcomes were documented and the phenotype was compared to the genotype. Succinyl dehydrogenase (SDH), Re-Arranged during Transfection (RET), Von-Hippel-Lindau (VHL) and NeuroFibromatosis-1 (NF1) mutations were studied. Additionally, immunohistochemisty for SDHB was also done, and the results compared to mutational analysis of SDH by MLPA (Multiplex Ligation-dependent Probe Activation). STATISTICAL ANALYSIS: Independent samples t-test and Fisher's exact test were used as appropriate. P values ≤0.05 were considered statistically significant. RESULTS: The mean age was 34.3 years. Of the 50 patients, 27 were males and 23 females. 10 patients (20%) in all were detected to have a genetic mutation. 6 patients possessed a RET mutation, while two had VHL mutations. No patient presented with a NF1 mutation. 2 patients had a SDH mutation, and Immunohistochemistry for SDHB correlated with mutational analysis for these patients. CONCLUSIONS: The proportion of patients with a familial variant of PCC/PGL is more than what the historic "Rule of Ten" suggests. Our study found that one in five patients have a genetic mutation. PCC/PGL patients with genetic mutations not only require more stringent follow-up, but also screening of family members.
