Evolution of Investigating Informed Assent Discussions about CPR in Seriously Ill Patients.

CONTEXT: Outcomes after cardiopulmonary resuscitation (CPR) remain poor. We have spent 10 years investigating an "informed assent" (IA) approach to discussing CPR with chronically ill patients/families. IA is a discussion framework whereby patients extremely unlikely to benefit from CPR are informed that unless they disagree, CPR will not be performed because it will not help achieve their goals, thus removing the burden of decision-making from the patient/family, while they retain an opportunity to disagree. OBJECTIVES: Determine the acceptability and efficacy of IA discussions about CPR with older chronically ill patients/families. METHODS: This multi-site research occurred in three stages. Stage I determined acceptability of the intervention through focus groups of patients with advanced COPD or malignancy, family members, and physicians. Stage II was an ambulatory pilot randomized controlled trial (RCT) of the IA discussion. Stage III is an ongoing phase 2 RCT of IA versus attention control in in patients with advanced chronic illness. RESULTS: Our qualitative work found the IA approach was acceptable to most patients, families, and physicians. The pilot RCT demonstrated feasibility and showed an increase in participants in the intervention group changing from "full code" to "do not resuscitate" within two weeks after the intervention. However, Stages I and II found that IA is best suited to inpatients. Our phase 2 RCT in older hospitalized seriously ill patients is ongoing; results are pending. CONCLUSIONS: IA is a feasible and reasonable approach to CPR discussions in selected patient populations.

Comparison between short and long-term outcomes after minimally invasive versus open primary liver resections for hepatocellular carcinoma: A 1:1 matched analysis.

BACKGROUND: This study aims to compare the short- and long-term outcomes of patients undergoing minimally invasive liver resection (MILR) versus open liver resection (OLR) for nonrecurrent hepatocellular carcinoma (HCC). METHODS: Review of 204 MILR and 755 OLR without previous LR performed between 2005 and 2018. 1:1 coarsened exact matching (CEM) and 1:1 propensity-score matching (PSM) were performed. RESULTS: Overall, 190 MILR were well-matched with 190 OLR by PSM and 86 MILR with 86 OLR by CEM according to patient baseline characteristics. After PSM and CEM, MILR was associated with a significantly longer operation time [230 min (interquartile range [IQR], 145-330) vs. 160 min (IQR, 125-210), p < .001] [215 min (IQR, 135-295) vs. 153.5 min (120-180), p < .001], shorter postoperative stay [4 days (IQR, 3-6) vs. 6 days (IQR, 5-8), p = .001)] [4 days (IQR, 3-5) vs. 6 days (IQR, 5-7), p = .004] and lower postoperative morbidity [40 (21%) vs. 67 (35.5%), p = .003] [16 (18.6%) vs. 27 (31.4%), p = .036] compared to OLR. MILR was also associated with a significantly longer median time to recurrence (70 vs. 40.3 months, p = .014) compared to OLR after PSM but not CEM. There was no significant difference in terms of overall survival and recurrence-free survival. CONCLUSION: MILR is associated with superior short-term postoperative outcomes and with at least equivalent long-term oncological outcomes compared to OLR for HCC.

Critical Appraisal of the Impact of Individual Surgeon Experience on the Outcomes of Minimally Invasive Distal Pancreatectomies: Collective Experience of Multiple Surgeons at a Single Institution.

BACKGROUND: Presently, there are limited studies analyzing the learning experience of minimally invasive distal pancreatectomies (MIDPs) and these frequently focused on a single surgeon or institution learning curve. This study aims to critically analyze the impact of individual surgeon experience on the outcomes of MIDP based on the collective experiences of multiple surgeons at a single institution. METHODS: A retrospective review of 90 consecutive MIDP from 2006 to 2018 was performed. These cases were performed by 13 surgeons over various time periods. The cohort was stratified into 4 groups according to individual surgeon experience. The case experience of these surgeons was as follows: <5 cases (n=8), 6 to 10 cases (n=2), 11 to 15 cases (n=2), and 30 cases (n=1). RESULTS: The distribution of the 90 cases were as follows: experience <5 cases (n=44), 6 to 10 cases (n=20), 11 to 15 cases (n=11), and 15 cases (n=15). As individual surgeons gained increasing experience, this was significantly associated with increasingly difficult resections performed, increased frequency of the use of robotic assistance and decreasing open conversion rates (20.5% vs. 100% vs. 9.1% vs. 0%, P=0.038). There was no significant difference in other perioperative outcomes. These findings suggest that the outcomes of MIDP in terms of open conversion rate could be optimized after 15 cases. Subset analyses suggested that the learning curve for MIDP of low difficulty was only 5 cases. CONCLUSION: MIDP can be safely adopted today and the individual surgeon learning curve for MIDP of all difficulties in terms of open conversion rate can be overcome after 15 cases.

Validation and Clinical Application of Interferon-Gamma Release Assay for Diagnosis of Latent Tuberculosis Infection in Children.

BACKGROUND: India has the highest tuberculosis (TB) burden, accounting for one-fifth of the global incidence and two-third of the cases in Southeast Asia with an estimated 1.9 million new cases every year. Identifying and treating latent TB infection (LTBI) can reduce the risk of development of active disease by up to 90%, thereby decreasing a major burden to the prevalence of the disease, and thus reducing potential sources in future. AIM: Early diagnosis of LTBI by tuberculin skin test (TST) and a newer interferon-gamma release assay (IGRA). MATERIALS AND METHODS: Seventy-seven clinically asymptomatic household contacts (≤18 years) of confirmed pulmonary TB patients were enrolled to compare the performance of TST and IGRA to diagnose LTBI. At baseline, all participants underwent testing for IGRA and TST. RESULTS: TST showed positivity of 22%, while IGRA demonstrated positivity of 40% in the diagnosis of latent TB. Kappa value at 95% confidence interval was 0.4753, indicates a moderate agreement between the two tests. This indicates that IGRA is a better predictor of latent TB. Maximum positive percentage was in the age group of 16-18 years in both the tests followed by 1-5 years. AIM: Early diagnosis of LTBI by tuberculin skin test (TST) and a newer interferon-gamma release assay (IGRA).

Prediction of Hepatocellular Carcinoma Recurrence Beyond Milan Criteria After Resection: Validation of a Clinical Risk Score in an International Cohort.

OBJECTIVE: This study aims to validate a previously reported recurrence clinical risk score (CRS). SUMMARY OF BACKGROUND DATA: Salvage transplantation after hepatocellular carcinoma (HCC) resection is limited to patients who recur within Milan criteria (MC). Predicting recurrence patterns may guide treatment recommendations. METHODS: An international, multicenter cohort of R0 resected HCC patients were categorized by MC status at presentation. CRS was calculated by assigning 1 point each for initial disease beyond MC, multinodularity, and microvascular invasion. Recurrence incidences were estimated using competing risks methodology, and conditional recurrence probabilities were estimated using the Bayes theorem. RESULTS: From 1992 to 2015, 1023 patients were identified, of whom 613 (60%) recurred at a median follow-up of 50 months. CRS was well validated in that all 3 factors remained independent predictors of recurrence beyond MC (hazard ratio 1.5-2.1, all P < 0.001) and accurately stratified recurrence risk beyond MC, ranging from 19% (CRS 0) to 67% (CRS 3) at 5 years. Among patients with CRS 0, no other factors were significantly associated with recurrence beyond MC. The majority recurred within 2 years. After 2 years of recurrence-free survival, the cumulative risk of recurrence beyond MC within the next 5 years for all patients was 14%. This risk was 12% for patients with initial disease within MC and 17% for patients with initial disease beyond MC. CONCLUSIONS: CRS accurately predicted HCC recurrence beyond MC in this international validation. Although the risk of recurrence beyond MC decreased over time, it never reached zero.

Telemedicine as a tool to provide family conferences and palliative care consultations in critically ill patients at rural health care institutions: a pilot study.

BACKGROUND: Many critically ill patients who transfer from rural hospitals to tertiary care centers (TCCs) have poor prognoses, and family members are unable to discuss patient prognosis and goals of care with TCC providers until after transfer. AIM: Our TCC conducted teleconferences prior to transfer to facilitate early family discussions. DESIGN/SETTING: We conducted a retrospective review of these telemedicine family conferences among critically ill patients requested for transfer which occurred from December 2008 to December 2009 at our TCC. Outcomes for each patient and detailed descriptions of the conference content were obtained. We also assessed limitations and attitudes and satisfaction with this intervention among clinicians. RESULTS: During the 12-month period, 12 telemedicine consultations were performed. Of these patients, 10 (83%) died in the 30 days following the request for transfer. After the telemedicine consultation, 8 (67%) patients were transferred to our TCC from their respective hospitals, while 4 (33%) patients continued care at their regional hospital and did not transfer. Of the patients who transferred to TCC, 7 (88% of those transferred) returned to their community after a stay at the TCC. CONCLUSION: This study demonstrates that palliative care consultations can be provided via telemedicine for critically ill patients and that adequate preparation and technical expertise are essential. Although this study is limited by the nature of the retrospective review, it is evident that more research is needed to further assess its applicability, utility, and acceptability.

Cardiopulmonary resuscitation among mechanically ventilated patients.

PURPOSE: To evaluate the outcomes, including long-term survival, after cardiopulmonary resuscitation (CPR) in mechanically ventilated patients. METHODS: We analyzed Medicare data from 1994 to 2005 to identify beneficiaries who underwent in-hospital CPR. We then identified a subgroup receiving CPR one or more days after mechanical ventilation was initiated [defined by ICD-9 procedure code for intubation (96.04) or mechanical ventilation (96.7x) one or more days prior to procedure code for CPR (99.60 or 99.63)]. RESULTS: We identified 471,962 patients who received in-hospital CPR with an overall survival to hospital discharge of 18.4 % [95 % confidence interval (CI) 18.3-18.5 %]. Of those, 42,163 received CPR one or more days after mechanical ventilation initiation. Survival to hospital discharge after CPR in ventilated patients was 10.1 % (95 % CI 9.8-10.4 %), compared to 19.2 % (95 % CI 19.1-19.3 %) in non-ventilated patients (p < 0.001). Among this group, older age, race other than white, higher burden of chronic illness, and admission from a nursing facility were associated with decreased survival in multivariable analyses. Among all CPR recipients, those who were ventilated had 52 % lower odds of survival (OR 0.48, 95 % CI 0.46-0.49, p < 0.001). Median long-term survival in ventilated patients receiving CPR who survived to hospital discharge was 6.0 months (95 % CI 5.3-6.8 months), compared to 19.0 months (95 % CI 18.6-19.5 months) among the non-ventilated survivors (p < 0.001 by logrank test). Of all patients receiving CPR while ventilated, only 4.1 % were alive at 1 year. CONCLUSIONS: Survival after in-hospital CPR is decreased among ventilated patients compared to those who are not ventilated. This information is important for clinicians, patients, and family members when discussing CPR in critically ill patients.

Multiple in-hospital resuscitation efforts in the elderly.

OBJECTIVES: The objective of this study was to determine the characteristics and survival rates of patients receiving cardiopulmonary resuscitation more than once during a single hospitalization. DESIGN: We analyzed inpatient Medicare data from 1992 to 2005 identifying beneficiaries 65 years old and older who underwent cardiopulmonary resuscitation more than once during the same hospitalization. MEASUREMENTS: We examined patient and hospital characteristics, survival to hospital discharge, factors associated with survival to discharge, median survival, and discharge disposition. RESULTS: We analyzed data from 421,394 patients who underwent cardiopulmonary resuscitation during the study period. Four lakh thirteen thousand four hundred three patients received cardiopulmonary resuscitation once during a hospitalization and survival was 17.7% with median survival after discharge being 20.6 months. There were 7,991 patients who received cardiopulmonary resuscitation more than once during the same hospitalization; 8.8% survived the efforts, and median survival after leaving the hospital was 10.5 months. Patients who received more than one episode of cardiopulmonary resuscitation during a hospitalization were significantly less likely to go home after discharge. Greater age, black race, higher burden of chronic illness, and receiving cardiopulmonary resuscitation in a larger or metropolitan hospital were associated with lower survival among patients receiving cardiopulmonary resuscitation more than once. CONCLUSIONS: Undergoing multiple cardiopulmonary resuscitation events during a hospitalization is associated with substantially reduced short- and long-term survival compared with patients who undergo cardiopulmonary resuscitation once. This information may be useful to clinicians when discussing end-of-life care with patients and families of patients who have experienced return of spontaneous circulation following in-hospital cardiopulmonary resuscitation but remain at risk for recurrent cardiac arrest.

OPTN gene: profile of patients with glaucoma from India.

PURPOSE: Optineurin gene (OPTN) mutations are reported in primary open angle glaucoma patients (POAG) from different populations. The coding and noncoding regions of OPTN were screened for mutations in 100 Indian high tension glaucoma patients (HTG). The frequency of the OPTN M98K mutation in an additional 120 patients (70 HTG and 50 normal tension glaucoma [NTG]) was analyzed by restriction enzyme digestion. METHODS: The HTG patients (about 40 years of age) were characterized by open angles on gonioscopy, with raised intraocular pressure (IOP) more than 21 mmHg (<21 mmHg on office diurnal phasing for NTG), and typical glaucomatous disc changes with corresponding visual field defects in the absence of any secondary cause. One hundred HTG patients and controls were screened for OPTN mutations by direct sequencing using an ABI prism 310/3100 Avant genetic analyzer. The M98K status was analyzed by restriction enzyme digestion with StuI. A genotype/phenotype correlation was also attempted for OPTN sequence alterations with clinical parameters such as age at diagnosis, intraocular pressure, cup:disc ratio, etc. The putative change in the transcription factor binding site for the IVS7 +24G>A polymorphism was attempted with AliBaba software (version 2.1). RESULTS: Six sequence alterations were observed in the 100 POAG patients by direct sequencing. The M98K substitution was observed in a total of 10 patients (7/170 HTG and 3/50 NTG) contributing to 4.1% in HTG and 6% in the NTG group and not in the controls. The IVS7+24G>A nucleotide change showed a significant difference in the HTG group (7/100) when compared to the control group (0/100) and found to be associated with increased IOP at diagnosis (p=0.03). The IVS7+24G>A polymorphism resulted in the creation of binding sites for transcription factors NF-1 and CPE that were not present in the wild type. CONCLUSIONS: The current study suggests a possible role of SNPs rather than mutations in OPTN in POAG pathology in the Indian population.

Hepatitis A outbreak in Hulu Langat District, Selangor State, Malaysia during April--October 2002.

A Hepatitis A outbreak occurred in Mukim Hulu Langat, Hulu Langat district from April 2002 to October 2002. Of the 51 cases notified, most were among students and the ethnic groups involved were Malays and the Orang Asli (local indigenous community). Epidemiological investigations revealed that the cases were localized along rivers used for recreational activities in this area. River water analysis indicated human faecal contamination and it was believed that the contamination was due to the Orang Asli community living upstream. This occurred due to lack of toilet facilities, water at point of use and the existing traditional practices of the Orang Asli community. Control measures instituted were intense health education to the Orang Asli to avoid using the rivers for defecation, multi agency efforts to provide sanitary toilets and adequate water to the villages affected. Future measures include conducting a sero- prevalence survey to determine the feasibility of Hepatitis A immunization to the susceptible population in this area. The outbreak that began in April 2002 was controlled by October 2002.

Dengue fever epidemic in Chennai--a study of clinical profile and outcome.

Children with dengue fever presenting to the Institute of Social Pediatrics, Government Stanley Hospital, during the months of October to December 2001, were prospectively followed up for clinical profile and outcome. Commonest clinical features were fever, vomiting, bleeding, body pain and hepatomegaly. Elevated liver enzymes and low platelet counts were common laboratory findings in dengue. Hepatomegaly, positive tourniquet test, elevated haematocrit and thrombocytopenia were more common in DHF and DSS group. Retro-orbital pain was slightly more in DHF and DSS groups and there was a tendency for DSS to present at an earlier age. There was no correlation between platelet counts and bleeding in classical dengue cases.
