RESUMEN
In the recent past, in order to achieve our national goal of 'health for all', National Medical Commission and Government of India made competency based medical education (CBME) mandatory in all Indian medical colleges. By undergoing CBME, the Indian Medical Graduate is expected to achieve the five roles of Clinician, Communicator, Leader and Member of the health care, Professional and Lifelong learner. This article is an overview of CBME, its relevant terminologies and knowledge-gaps. The purpose is to share these changes in medical education with practicing Otolaryngologists of India. It also discusses the various challenges regarding this already- suggested implementation process for clinical academicians, which could be counterproductive to the expected national aim and goal.
RESUMEN
Background/Objectives: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis is a significant cause of hospital admission and the leading reason for admission to the ICU and is associated with high mortality. Vitamin D has shown promising immunomodulatory effects by upregulating the antimicrobial peptide, cathelicidin. However, previous studies analysing the use of calcitriol in sepsis have shown variable results and did not utilise APACHE II (Acute Physiology and Chronic Health Evaluation II) scores as endpoints. This study evaluates the efficacy of intramuscular calcitriol in patients admitted to the ICU with sepsis, focusing on its impact on APACHE II scores. The primary aim was to determine if intramuscular calcitriol improved APACHE II scores from day 1 to day 7 or discharge from the ICU, whichever was earlier. Secondary outcomes included 28-day mortality, ventilator days, vasopressor days, ICU stay length, adverse events, and hospital-acquired infections in ICU patients. Methods: This was a triple-blinded phase III randomised control trial. A total of 152 patients with suspected sepsis were block-randomised to receive either intramuscular calcitriol (300,000 IU) (n = 76) or a placebo (n = 76). The trial was registered with the Clinical Trials Registry-India (CTRI No: CTRI 2019/01/17066) following ethics committee approval and was not funded. Results: There was no significant difference in APACHE II scores between the calcitriol and placebo groups from day 1 to day 7 (p = 0.382). There were no significant changes in 28-day mortality (14.4% vs. 17%, p = 0.65), number of days on a ventilator (5 vs. 5, p = 0.84), number of days on vasopressors (3 vs. 3, p = 0.98), length of ICU stay (10 days vs. 11 days, p = 0.78), adverse events (27.6% vs. 19.7%, p = 0.25), and hospital-acquired infections (17.1% vs. 15.8%, p = 0.82). Conclusions: There was no effect of intramuscular calcitriol in patients admitted to the ICU with sepsis.
RESUMEN
Endoscopic adenoidectomy with powered instruments,a challenge in resource-constraint developing countries, has been on the rise. To evaluate conventional curettage as compared to endoscopic assisted adenoidectomy in the successful management of adenoid enlargement. A randomized controlled double-blinded study among children undergoing adenoidectomywas done. Primary outcomes were assessed by pre- and postoperative evaluation with a symptoms questionnaire and fiberoptic nasal endoscopy. There were 71 children aged 3-15 years, majority having grade III adenoids. Conventional adenoidectomy was done by the surgeon who was blinded to preoperative adenoid status. Patients were randomized to two groups, 35in conventional curettage where no further on-table intervention was done. Check endoscopyof the remaining 36 patients, formingthe second group, revealed residual grade III adenoidsin 5.6%. They underwentcompletion adenoidectomyendoscopically. By the 12th postoperative week, nasal endoscopy noted that 39.3% had grade I/II and 8.8% had grade I in the conventional and endoscopic groups respectively. Thoughstatistically significant, all pre-op symptoms settled except sleep-related ones which persisted in both groups (25% versus 14.7) with no complications in either group. Relief of all symptoms other than sleep-related ones, was achieved despite residual adenoids being up to grade II in both conventional and endoscopic group. This suggests non-obstructive causes in a subset of these patients. Conventional adenoid curettage is comparable to endoscopic adenoidectomy by cold method among children aged three and above. Complete adenoidclearance for achieving 'anatomical success' appears not to be necessary for 'clinical success'.
RESUMEN
Oral iron is the mainstay of treating iron deficiency anemia. Recent studies indicate better fractional iron absorption with alternate day supplementation. However, the optimal supplementation strategy is unclear. We compared effectiveness of daily versus alternate day supplementation of oral iron for treatment of iron deficiency anemia. This double blind, active control, randomized controlled trial was conducted on two hundred adults having hemoglobin 10 g/dL or less with microcytic hypochromic anemia and/or serum ferritin below 50 ng/mL. They were randomized to receive either two Ferrous sulfate tablets containing 60 mg elemental iron (120 mg total) on alternate days or single tablet of 60 mg elemental iron daily for 8 weeks. Primary outcome was mean change in hemoglobin at week 8 from baseline. Mean hemoglobin was 6.53 (± 1.89) and 6.68 (± 1.89) g/dL in the alternate day and daily arms respectively. Mean change in hemoglobin was + 1.05 ± 1.34 g/dL in alternate day arm and + 1.36 ± 1.51 g/dL in daily arm (p = 0.47) at week 8. There were no statistically significant differences between the arms with respect to any secondary outcome. There is no significant difference between alternate day and daily iron administration in improving hemoglobin. Randomized controlled trials enrolling more participants for longer periods of supplementation and evaluating clinically relevant outcomes like change in hemoglobin may be useful in identifying the ideal dosing strategy.Trial Registration: Clinical Trial Registry of India (CTRI/2019/01/017169).

BACKGROUND: The mechanisms that control local and systemic inflammation in scrub typhus have only been partially elucidated. The wingless (Wnt) signaling pathways are emerging as important regulators of inflammation and infection, but have not been investigated in scrub typhus. METHODOLOGY/PRINCIPAL FINDINGS: Plasma levels of secreted Wnt antagonists (i.e. DKK-1, sFRP-3, WIF-1 and SOST) were analyzed in patients with scrub typhus (n = 129), patients with similar febrile illness without O. tsutsugamushi infection (n = 31), febrile infectious disease controls, and in healthy controls (n = 31) from the same area of South India, and were correlated to markers of inflammation, immune and endothelial cell activation as well as for their association with organ specific dysfunction and mortality in these patients. We found i) Levels of SOST and in particular sFRP-3 and WIF-1 were markedly increased and DKK-1 decreased in scrub typhus patients at admission to the hospital compared to healthy controls. ii) In recovering scrub typhus patients, SOST, sFRP-3 and WIF-1 decreased and DKK-1 increased. iii) SOST was positively correlated with markers of monocyte/macrophage and endothelial/vascular activation as well as with renal dysfunction and poor outcome iv) Finally, regulation of Wnt pathways by O. tsutsugamushi in vitro in monocytes and ex vivo in mononuclear cells isolated from patients with scrub typhus, as evaluated by gene expression studies available in public repositories, revealed markedly attenuated canonical Wnt signaling. CONCLUSIONS/SIGNIFICANCE: Our findings suggest that scrub typhus is characterized by attenuated Wnt signaling possibly involving dysregulated levels of several secreted pathway antagonists. The secreted Wnt antagonist SOST was strongly associated with renal dysfunction and poor prognosis in these patients.

Multidisciplinary treatment and multimodal analgesia are the approach to reduce mortality and morbidity of breast cancer. Pectoral nerve block (PECS I and II) is one of the modes of analgesia advocated. The primary aim is to find the risks and benefits of the block in providing analgesia for intraoperative and immediate postoperative cancer-related breast surgery and total morphine consumption. The secondary aim is to evaluate, any additional knowledge acquired, in the reduction of persistent chronic pain state and cancer recurrence, during the time frame studied. The study was conducted after the approval of the ethics committee and National Registry, and included patients of ASA I and II undergoing mastectomy surgery with axillary clearance, under general anesthesia, during the period of 2017 to 2018. A total of 60 patients were recruited, randomizing them into two groups: group 1 (n = 30): ultrasound-guided PECS I (0.2 ml/kg) and PECS II (0.4 ml/kg) block, post-induction with 0.25% levobupivacaine, maximum dose of 2 mg/kg; group 2 (n = 30): no block, only general anesthesia. Intraoperatively, vitals were monitored at regular intervals and analgesics given as per response. Postoperatively, pain was assessed using the numerical pain score and arm abduction score, until discharge. Data collected was analyzed and interpreted using statistical methods. Patients were followed up telephonically, until six months for any chronic pain and cancer recurrence instances. The PECS block group used less morphine intra and postoperatively, which was statistically significant (p = 0.0001). Group 1- Had a significant decrease in the mean intraoperative systolic blood pressure (p = 0.03). There was significant improvement in the arm abduction in the test group as compared to that in the control group (p = 0.001). The average time for block performance was 7.9 min and no complications were observed. No patients in the study groups reported chronic pain or cancer recurrence issues. The two-level PECS block is safe, effective, reliable, and easy to perform. Clinical Trial Registration Number: CTRI/2017/11/010630.
RESUMEN
OBJECTIVE: An independent external evaluation of the International Clinical Epidemiology Network (INCLEN) research program to emphasize the public health significance of childhood pneumonia in India. METHOD: An independent evaluation based on desk reviews of available documents and reports, site visits to study sites, and structured interviews with study investigators, technical advisory group (TAG) members, INCLEN staff and the donor agency. FINDINGS: The program elicited responses from a range of investigators across India. The selection process was transparent and objective, and the selected projects were of public health significance. The support provided through the program strengthened research capacity and improved study outputs. However, the available expertise was not fully exploited and protocol deviations in a few studies resulted in suboptimal outputs. CONCLUSIONS: The program represented a new and positive paradigm for research support in India, though a few improvements may result in greater impact for future programs.

PURPOSE: To investigate the epidemiology of invasive pneumococcal disease (IPD), prevalent serotypes, and pattern of antimicrobial resistance (AMR) in Indian adults. METHODS: Prospective laboratory based surveillance of IPD was carried out in >18 years age group between January 2007 and July 2017, from a tertiary care hospital in South India. All Streptococcus pneumoniae culture positives from blood, CSF and sterile body fluids were characterized to identify the serotypes and AMR. RESULTS: A total of 408 IPD cases were characterized in this study. The overall case fatality rate in this study was 17.8% (95% confidence interval (CI): 14.1, 22.4). Pneumonia (39%), meningitis (24.3%), and septicaemia (18.4%) were the most common clinical conditions associated with IPD. Serotypes 1, 3, 5, 19F, 8, 14, 23F, 4, 19A and 6B were the predominant serotypes in this study. Penicillin non-susceptibility was low with 6.4% CONCLUSION: Serotype data from this study helped in accurate estimation of pneumococcal conjugate vaccine-13 and pneumococcal polysaccharide vaccine-23 protective coverage against serotypes causing IPD in India as 58.7% (95% CI: 53.8, 63.4) and 67.4% (95% CI: 62.7, 71.8) respectively. Penicillin non-susceptibility in meningeal IPD cases is 27.4%. Empirical therapy for meningeal IPD must be cephalosporin in combination with vancomycin since cefotaxime non-susceptibility in meningeal IPD is 9.9.

BACKGROUND: Admission of a patient to an intensive care unit (ICU) can result in tremendous stress to family caregivers not only because of the need to provide physical and emotional support to the sick relative, but also due to the burden of decision-making on behalf of the critically ill person. We enquired about family caregivers' perspectives on intensive care, the challenges they faced with decision-making and their perceptions on the nature of their interactions with healthcare providers. METHODS: We used maximum variation sampling and enrolled 20 consenting caregivers for semi-structured interviews. Each interview, based on an interview guide, took 30-40 minutes and was conducted in a private place within the hospital premises. All interviews were recorded, transcribed verbatim and entered into a qualitative software (NVivo) for analysis. RESULTS: The three emergent themes of analysis were (i) understanding about ICU, (ii) decision-making concerning ongoing treatment; and (iii) relationship with healthcare-providers. Some respondents saw the intensive care as an expensive facility for seriously ill patients while others were not so clear. The family's relationship with the patient and their financial status were seen as important deciding factors in continuing treatment. Decision-making was a complex and emotional issue and doctors were held in awe and seen as the main deciding authority. The importance of doctors being compassionate and communicative was stressed. CONCLUSION: Our study highlights the problems faced by family caregivers and of the need to improve their satisfaction through clear and simple communication strategies.

PURPOSE: Pneumococcal meningitis is a life-threatening infection, requiring prompt diagnosis and effective treatment. Penicillin resistance in pneumococcal infections is a concern. Here, we present the antibiotic susceptibility profile of pneumococcal meningeal isolates from January 2008 to August 2016 to elucidate treatment guidelines for pneumococcal meningitis. MATERIALS AND METHODS: Invasive pneumococcal isolates from all age groups, were included in this study. Minimum inhibitory concentrations for the isolates were identified by agar dilution technique and VITEK System 2. Serotyping of isolates was done by co-agglutination technique. RESULTS: Out of 830 invasive pneumococcal isolates, 167 (20.1%) isolates were from meningeal infections. Cumulative penicillin resistance in pneumococcal meningitis was 43.7% and cefotaxime non-susceptibility was 14.9%. Penicillin resistance amongst meningeal isolates in those younger than 5 years, 5-16 years of age and those aged 16 years and older was 59.7%, 50% and 27.3%, respectively, with non-susceptibility to cefotaxime in the same age groups being 18%, 22.2% and 10.4%. Penicillin resistance amongst pneumococcal meningeal isolates increased from 9.5% in 2008 to 42.8% in 2016, whereas cefotaxime non-susceptibility increased from 4.7% in 2008 to 28.5% in 2016. Serotypes 14, 19F, 6B, 6A, 23F, 9V and 5 were the most common serotypes causing meningitis, with the first five accounting for over 75% of resistant isolates. CONCLUSIONS: The present study reports increasing penicillin resistance and cefotaxime non-susceptibility to pneumococcal meningitis in our setting. This highlights the need for empiric therapy with third-generation cephalosporins and vancomycin for all patients with meningitis while awaiting results of culture and susceptibility testing.

BACKGROUND: Meningococcal disease can lead to death or disability within hours after onset. Pre-admission antibiotics aim to reduce the risk of serious disease and death by preventing delays in starting therapy before confirmation of the diagnosis. OBJECTIVES: To study the effectiveness and safety of pre-admission antibiotics versus no pre-admission antibiotics or placebo, and different pre-admission antibiotic regimens in decreasing mortality, clinical failure, and morbidity in people suspected of meningococcal disease. SEARCH METHODS: We searched CENTRAL (6 January 2017), MEDLINE (1966 to 6 January 2017), Embase (1980 to 6 January 2017), Web of Science (1985 to 6 January 2017), LILACS (1982 to 6 January 2017), and prospective trial registries to January 2017. We previously searched CAB Abstracts from 1985 to June 2015, but did not update this search in January 2017. SELECTION CRITERIA: Randomised controlled trials (RCTs) or quasi-RCTs comparing antibiotics versus placebo or no intervention, in people with suspected meningococcal infection, or different antibiotics administered before admission to hospital or confirmation of the diagnosis. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data from the search results. We calculated the risk ratio (RR) and 95% confidence interval (CI) for dichotomous data. We included only one trial and so did not perform data synthesis. We assessed the overall quality of the evidence using the GRADE approach. MAIN RESULTS: We found no RCTs comparing pre-admission antibiotics versus no pre-admission antibiotics or placebo. We included one open-label, non-inferiority RCT with 510 participants, conducted during an epidemic in Niger, evaluating a single dose of intramuscular ceftriaxone versus a single dose of intramuscular long-acting (oily) chloramphenicol. Ceftriaxone was not inferior to chloramphenicol in reducing mortality (RR 1.21, 95% CI 0.57 to 2.56; N = 503; 308 confirmed meningococcal meningitis; 26 deaths; moderate-quality evidence), clinical failures (RR 0.83, 95% CI 0.32 to 2.15; N = 477; 18 clinical failures; moderate-quality evidence), or neurological sequelae (RR 1.29, 95% CI 0.63 to 2.62; N = 477; 29 with sequelae; low-quality evidence). No adverse effects of treatment were reported. Estimated treatment costs were similar. No data were available on disease burden due to sequelae. AUTHORS' CONCLUSIONS: We found no reliable evidence to support the use pre-admission antibiotics for suspected cases of non-severe meningococcal disease. Moderate-quality evidence from one RCT indicated that single intramuscular injections of ceftriaxone and long-acting chloramphenicol were equally effective, safe, and economical in reducing serious outcomes. The choice between these antibiotics should be based on affordability, availability, and patterns of antibiotic resistance.Further RCTs comparing different pre-admission antibiotics, accompanied by intensive supportive measures, are ethically justified in people with less severe illness, and are needed to provide reliable evidence in different clinical settings.

AIM: To study the impact of hospital-acquired infections (HAIs) on cost and outcome from intensive care units (ICU) in India. METHODS: Adult patients (> 18 years) admitted over 1-year, to a 24-bed medical critical care unit in India, were enrolled prospectively. Treatment cost and outcome data were collected. This cost data was merged with HAI data collected prospectively by the Hospital Infection Control Committee. Only infections occurring during ICU stay were included. The impact of HAI on treatment cost and mortality was assessed. RESULTS: The mean (± SD) age of the cohort (n = 499) was 42.3 ± 16.5 years. Acute physiology and chronic health evaluation-II score was 13.9 (95%CI: 13.3-14.5); 86% were ventilated. ICU and hospital length of stay were 7.8 ± 5.5 and 13.9 ± 10 d respectively. Hospital mortality was 27.9%. During ICU stay, 76 (15.3%) patients developed an infection (ventilator-associated pneumonia 50; bloodstream infection 35; urinary tract infections 3), translating to 19.7 infections/1000 ICU days. When compared with those who did not develop an infection, an infection occurring during ICU stay was associated with significantly higher treatment cost [median (inter-quartile range, IQR) INR 92893 (USD 1523) (IQR 57168-140286) vs INR 180469 (USD 2958) (IQR 140030-237525); P < 0.001 and longer duration of ICU (6.7 ± 4.5 d vs 13.4 ± 7.0 d; P < 0.01) and hospital stay (12.4 ± 8.2 d vs 21.8 ± 13.9 d; P < 0.001)]. However ICU acquired infections did not impact hospital mortality (31.6% vs 27.2%; P = 0.49). CONCLUSION: An infection acquired during ICU stay was associated with doubling of treatment cost and prolonged hospitalization but did not significantly increase mortality.
RESUMEN
Background: Since the time of NACO Antiretroviral (ART) roll-out, generic ART has been the mainstay of therapy. There are many studies documenting the efficacy of generic ART but with the passage of time, failure of therapy is on the rise. As institution of second line ART has significant financial implications both for a program and for an individual it is imperative that we determine factors which contribute towards treatment failure in a cohort of patients on generic antiretroviral therapy. Methodology: This was a nested matched case-control study assessing the predictors for treatment failure in our cohort who had been on Anti-retroviral therapy for at least a year. We identified 42 patients (Cases) with documented treatment failure out of our cohort of 823 patients and 42 sex, age and duration of therapy-matched controls. Using a structured proforma, we collected information from the out-patient and in-patient charts of the Infectious Diseases clinic Cohort in CMC, Vellore. A set of predetermined variables were studied as potential risk factors for treatment failure on ART. Results: Univariate analysis showed significant association with 1) Self-reported nonadherence<95% [OR 12.81 (95%CI 1.54-281.45)]. 2) Treatment interruptions in adherent cases (OR 9.56 (95% CI 1.11-213.35)]. 3) Past inappropriate therapies [OR 9.65 (95% CI 1.12-215.94)]. 4) Diarrhoea [OR 16.40 (95% CI 2.02-3.55.960]. 5) GI opportunistic infections (OR 11.06 (95% CI 1.31 -244.27)] and 6) Drug Toxicity [OR 3.69 (95% CI 1.15-12.35).In multiple logistic regression analysis, we found independent risk factors of treatment failure to be: Self-reported non-adherence (<95%) with OR 15.46(95%CI 1.55 - 154.08), drug toxicity - OR 4.13(95%CI 1.095 - 15.534) and history of diarrhoea - OR 23.446(95%CI 2.572 - 213.70). Conclusion: This study reveals that besides adherence to therapy, presence of diarrhoea and occurrence of drug toxicity are significant risk factors associated with failure of anti-retroviral therapy. There is a need for further prospective studies to assess their role in development of treatment failure on ART and thus help development of targeted interventions.

OBJECTIVES: To evaluate the degree of agreement between the intraoperative frozen section (FS) reporting of central nervous system (CNS) tumors and final histopathological diagnosis based on permanent paraffin section. METHODS: All CNS tumor cases with a diagnosis at FS and subsequent permanent section (n = 261) taken from 2007 to 2012 were retrospectively reviewed. Twenty percent of FS were double-checked by a senior pathologist as part of the study and the intraobserver agreement between the pathologist and the agreement between final report, and initial FS report was estimated by the intraclass correlation coefficient (ICC). RESULTS: A total of 261 cases were reviewed. The most common diagnosis was glioblastoma (grade IV) and meningioma (grade I-II) forming 45.6% of cases. Fifty-three cases were subjected to intraobserver agreement of histological diagnosis. There was nearly perfect intraobserver agreement on histopathology (ICC = 0.9). Out of 261 cases, 224 cases showed a strong agreement between the FS diagnosis and final histological diagnosis (ICC = 0.747). A discrepancy between the FS and final diagnosis were found in eight cases. The disagreement did not relate to any specific tumor type. However, in three cases, the discrepancy was in the grading of the glioma. In 29 cases, a definite opinion could not be given on FS as the samples examined were nonrepresentative. CONCLUSIONS: Histopathological slides classified by World Health Organization criteria of CNS tumors had excellent intraobserver agreement. Our results show a moderate to high degree of agreement in the intraoperative diagnosis of CNS lesions using FS. However, there are limitations, and some lesions are a diagnostic challenge. There is a need to improve our diagnostic skills and knowledge of possible errors and establish better communication with neurosurgeons.
RESUMEN
For accurate and earlier detection of invasive pneumococcal serogroup/serotypes from India, we have rearranged the African sequence of multiplex PCR provided by the Centers for Disease Control and Prevention, USA. This modified approach can successfully be adapted for earlier serotype detection of 95% of the pneumococcal strains prevalent in India.

OBJECTIVES: The majority of patients in India access private sector providers for curative medical services. However, there is scanty information on the cost of treatment of critically ill patients in this setting. The study evaluates the cost and extent of financial subsidy required for patients admitted to an intensive care unit (ICU) in India. METHODS: Data on direct medical, direct nonmedical, and indirect cost were prospectively collected from critically ill patients admitted to a tertiary teaching hospital in India. Willingness-to-pay (WTP) amount was obtained from the next-of-kin following admission and the actual cost paid by the family at discharge was recorded. RESULTS: The main diagnoses (n = 499) were infection (26 percent) and poisoning (21 percent). The mean APACHE-II score was 13.9 (95 percent confidence interval [CI], 13.3-14.5); 86 percent were ventilated. ICU stay was 7.8 days (95 percent CI, 7.3-8.3). Hospital mortality was 27.9 percent. Direct medical cost accounted for 77 percent (US$ 2164) of the total treatment cost (US$ 2818). Indirect cost and direct nonmedical cost contributed to 19 percent (US$ 547.5) and 4 percent (US$ 106.5), respectively. Average total and daily ICU cost were US$ 1,897 and US$ 255, respectively. Although the family's WTP was 53 percent (US$ 1146; 95 percent CI, 1090-1204) of direct medical cost, their final contribution was 67.7 percent (US$ 1465; 95 percent CI, 1327-1604). CONCLUSIONS: The cost of an ICU admission in our setting is US$ 2818. Although the family's contribution to expenses exceeded their initial WTP, a substantial subsidy (33 percent) is still required. Alternate financing strategies for the poor and optimization of ICU resources are urgently required.

BACKGROUND: Trauma is an increasing cause of morbidity and mortality in India. This study was done to improve the understanding of the mode of trauma, severity of injuries, and outcome of trauma victims in our hospital. MATERIALS AND METHODS: This was a retrospective observational study of all adult trauma patients more than 18-year-old presenting to our emergency department (ED). Details of the incident, injuries, and outcome were noted. RESULTS: The ED attended to 16,169 patients during the 3-month study period with 10% (1624/16,169) being adult trauma incidents. The gender distribution was 73.6% males and 26.4% females. The mean age was 40.2 ± 16.7 years. The median duration from time of incident to time of arrival to the ED was 3 h (interquartile range [IQR]: 1.5-6.5) for priority one patients, 3 h (IQR: 1.5-7.7) for priority two patients, and 1.5 h (IQR: 1-7) for priority three patients. The average number of trauma incidents increased by 28% during the weekends. Road traffic accident (RTA) (65%) was the most common mode of injury, followed by fall on level ground (13.5%), fall from height (6.3%), work place injuries (6.3%), and others. Traumatic brain injury was seen in 17% of patients while 13.3% had polytrauma with two-wheeler accidents contributing to the majority. The ED team alone managed 23.4% of patients while the remaining 76.6% required evaluation and treatment by the trauma, surgical teams. The in-hospital mortality rate was 2.3%. Multivariate analysis showed low Glasgow coma score (odds ratio [OR]: 0.65, 95% confidence interval [CI]: 0.55-0.76, P < 0.001) and high respiratory rate (OR: 1.15, 95% CI: 1.07-1.24, P < 0.001) to be independent predictors of mortality among polytrauma victims. CONCLUSIONS: RTA and falls are the predominant causes of trauma. A simple physiological variable-based scoring system such as the revised trauma score may be used to prioritize patients with polytrauma.
RESUMEN
RATIONALE: Intensive care unit (ICU) treatment costs pose special challenges in developing countries. OBJECTIVES: To determine the prognostic value of the "utility" score and evaluate the relationship of willingness to pay assessment to utility score during ICU admission. METHODS: We performed a prospective study spanning 12 months in a 24-bed medical ICU in India. Treatment cost was estimated by direct measurement. Global utility score was assessed daily by healthcare providers on a Likert scale (0-1 in increments of 0.1, with 0 indicating death/severe disability and 1 indicating cure/perfect health). The sensitivity, specificity, and likelihood ratios of utility in predicting ICU mortality was calculated. Receiver operating characteristic curves were generated to compare Day 2 utility with APACHE II. The caregiver's willingness to pay for treatment was assessed on alternate days using the bidding method by presenting a cost bid. Based on the response ("yes" or "no"), bids were increased or decreased in a prespecified manner until a final bid value was reached. Simultaneously, treating doctors were asked how much institutional funds they would be willing to spend for treatment. MEASUREMENTS AND MAIN RESULTS: Primary diagnosis in 499 patients included infection (26%) and poisoning (21%). The mean (SD) APACHE II score was 13.9 (5.8); 86% were ventilated. ICU stay was 7.8 (5.5) days. ICU mortality was 23.9% (95% confidence interval, 20.3-27.8). Survival without disability was 8.3% (2/24) for Day 2 utility score ≤0.3 and 95.8% (53/56) for Day 5 score >0.8 (P < 0.001). The likelihood ratio to predict mortality increased as utility values decreased and was highest (5.85) for utility 0.2. Area under the receiver operating characteristic curves for utility and APACHE II were similar. Willingness to pay by the caregiver was 53% of treatment cost and was not influenced by utility. Willingness to pay by ICU doctors showed an inverted U-shaped relationship with utility. CONCLUSIONS: Utility scores help prognosticate, with Day 2 score ≤0.3 associated with poor outcome and ≥0.8 Day 5 score with survival. The caregiver's willingness to pay was inadequate to meet treatment cost. ICU doctors were willing to spend more for moderate utility scores than for very high or low utility values. Further prospective studies are needed to optimize the utilization of scarce ICU resources by identifying patients for appropriate step-down care using utility and willingness to pay.
