RESUMO

Background: Use of telemedicine for healthcare delivery in the emergency department can increase access to specialized care for pediatric patients without direct access to a children's hospital. Currently, telemedicine is underused in this setting. Objectives: This pilot research project aimed to evaluate the perceived effectiveness of a telemedicine program in delivering care to critically ill pediatric patients in the emergency department by exploring the experiences of parents/caregivers and physicians. Methods: Sequential explanatory mixed methods were employed, in which quantitative methods of inquiry were followed by qualitative methods. Data were collected through a post-used survey for physicians, followed by semi-structured interviews with physicians and parents/guardians of children treated through the program. Descriptive statistics were used to analyze the survey data. Reflexive thematic analysis was used to analyze interview data. Results: The findings describe positive perceptions of telemedicine for emergency department pediatric care, as well as barriers and facilitators to its use. The research also discusses implications for practice and recommendations for overcoming barriers and supporting facilitators when implementing telemedicine programming. Conclusion: The findings suggest that a telemedicine program has utility and acceptance among parents/caregivers and physicians for the treatment of critically ill pediatric patients in the emergency department. Benefits recognized and valued by both parents/caregivers and physicians include rapid connection to sub-specialized care and enhanced communication between remote and local physicians. Sample size and response rate are key limitations of the study.

RESUMO

The spread of SARS-COVID 19 infection has resulted in accelerated efforts at development and dissemination of vaccines throughout the globe. These vaccines have different mechanisms of actions and their efficacy and side effects are being monitored. There have been rare reports in literature of thyroid dysfunction after COVID-19 vaccine administration. Sub-acute thyroiditis is one such complication which can arise as a rare side-effect of vaccination. This has also been reported as a symptom of COVID-19 infection. Clinical features include fever, neck pain, palpitations and weight loss. We report sub-acute thyroiditis in a 50-year-old male who presented with symptoms suggestive of thyroid abnormality one day after receiving the inactivated COVID-19 vaccine (CoronaVac Sinovac-Biotech Ltd).

RESUMO

OBJECTIVES: Sepsis is a life-threatening medical emergency. There is a paucity of information on whether quality improvement approaches reduce the in-hospital sepsis caseload or save lives and decrease the healthcare system and society's cost at the provincial/national levels. This study aimed to assess the outcomes and economic impact of a province-wide quality improvement initiative in Canada. DESIGN: Retrospective population-based study with interrupted time series and return on investment analyses. SETTING: The sepsis cases and deaths averted over time for British Columbia were calculated and compared with the rest of Canada (excluding Quebec and three territories). PATIENTS: Aggregate data were obtained from the Canadian Institute for Health Information on risk-adjusted in-hospital sepsis rates and sepsis mortality in acute care sites across Canada. INTERVENTIONS: In 2012, the British Columbia Sepsis Network was formed to reduce sepsis occurrence and mortality through education, knowledge translation, and quality improvement. MEASUREMENTS AND MAIN RESULTS: A return on investment analysis compared the financial investment for the British Columbia Sepsis Network with the savings from averted sepsis occurrence and mortality. An estimated 981 sepsis cases and 172 deaths were averted in the post-British Columbia Sepsis Network period (2014-2018). The total cost, including the development and implementation of British Columbia Sepsis Network, was $449,962. Net savings due to cases averted after program costs were considered were $50.6 million in 2018. This translates into a return of $112.5 for every dollar invested. CONCLUSIONS: British Columbia Sepsis Network appears to have averted a greater number of sepsis cases and deaths in British Columbia than the national average and yielded a positive return on investment. Our findings strengthen the policy argument for targeted quality improvement initiatives for sepsis care and provide a model of care for other provinces in Canada and elsewhere globally.

RESUMO

Here, we introduce the current stage and future directions of the wireless infrastructure of the Korea Research Environment Open NETwork (KREONET), a representative national research and education network in Korea. In 2018, ScienceLoRa, a pioneering wireless network infrastructure for scientific applications based on low-power wide-area network technology, was launched. Existing in-service applications in monitoring regions, research facilities, and universities prove the effectiveness of using wireless infrastructure in scientific areas. Furthermore, to support the more stringent requirements of various scientific scenarios, ScienceLoRa is evolving toward ScienceIoT by employing high-performance wireless technology and distributed computing capability. Specifically, by accommodating a private 5G network and an integrated edge computing platform, ScienceIoT is expected to support cutting-edge scientific applications requiring high-throughput and distributed data processing.

RESUMO

BACKGROUND: A significant concern for rural patients is the cost of travel outside of their community for specialist and diagnostic care. Often, these costs are transferred to patients and their families, who also experience stress associated with traveling for care. We sought to examine the rural patient experience by (1) estimating and categorizing the various out of pocket costs associated with traveling for healthcare and (2) describing and measuring patient stress and other experiences associated with traveling to seek care, specifically in relation to household income. METHODS: We have designed and administered an online, retrospective, cross-sectional survey seeking to estimate the out-of-pocket (OOP) costs and personal experiences of rural patients associated with traveling to access health care in British Columbia. Respondents were surveyed across five categories: Distance Traveled and Transportation Costs, Accommodation Costs, Co-Traveler Costs, Lost Wages, and Patient Stress. Bivariate relationships between respondent household income and other numerical findings were investigated using one-way ANOVA. RESULTS: On average, costs for respondents were $856 and $674 for transport and accommodation, respectively. Strong relationships were found to exist between the distance traveled and total transport costs, as well as between a patient's stress and their household income. Patient perspectives obtained from this survey expressed several related issues, including the physical and psychosocial impacts of travel as well as delayed or diminished care seeking. CONCLUSIONS: These key findings highlight the existing inequities between rural and urban patient access to health care and how these inequities are exacerbated by a patient's overall travel-distance and financial status. This study can directly inform policy related efforts towards mitigating the rural-urban gap in access to health care.

RESUMO

BACKGROUND: Potentially inappropriate use of antipsychotics (PIUA) raises serious concerns about safety, quality, and cost of care for residents in long-term care (LTC). OBJECTIVE: This study aimed to estimate the cost-effectiveness of the Call for Less Antipsychotics in Long-Term Care (Clear) initiative compared with the status quo (pre-Clear, baseline). METHODS: A model-based cost-utility analysis, from a public-payer perspective in British Columbia, was conducted using secondary data of residents in LTC homes from 2013 to 2019. Residents' health resource utilization and quality-adjusted life-year (QALY) measures were extracted from multiple administrative databases. Six Markov states were modelled for post-antipsychotic progression representing PIUA, appropriate use of antipsychotic, complete withdrawal, and death. The primary outcome was the incremental cost per QALY gained. RESULTS: A cohort of 35,669 residents was included in the primary analysis. The Clear initiative, over 10 years, was estimated to have an incremental cost-effectiveness ratio (ICER) of CA$26,055 (2020 Canadian dollars) per QALY gained at an incremental cost of CA$5211 per resident and a QALY gain of 0.20. In the subgroup analyses, our findings were even more favourable for Clear wave 2 (ICER of CA$24,447 per QALY gained) and Clear wave 3 (ICER of CA$25,933 per QALY gained). At a willingness-to-pay of CA$50,000 per QALY gained, the probabilities of Clear waves 2 and 3 were 82% cost-effective. CONCLUSION: This study demonstrated incremental costs and yielded favourable ICERs for Clear compared with the baseline. More research is needed to understand the level of support for individual care homes to sustain the Clear initiative in the long run.

RESUMO

Smartphones are now commonly used, for virtual outpatient consultations, to help reduce disease transmission during the COVID-19 pandemic. Nosocomial spread of COVID 19 and hospital acquired infections are usually from staff or students to patients. Reducing non- essential staff numbers on ward rounds may reduce the risk. We describe the novel use of smartphones, with Microsoft Teams, to live stream inpatient interactions, radiological images, pathology results, charts and patient review between an office-based and ward team (virtual ward round) and for teaching medical students in secondary care. After Research and Ethics, Digital services and Information Governance approval we compared a smartphone and head-worn device (Realwear HMT-1). Data collection was by participant questionnaire. Statistical analysis was performed using the Mann - Whitney test. There was no statistically significant difference in audio and video feed quality between the smart phone (p value = 0.3) and Realwear device (p value = 0.41). However the smartphone was preferred during ward rounds and was 85% cheaper than the Realwear device. Urology medical staff numbers on the ward were reduced by 50%. Ward round efficiency improved as administrative tasks could be performed by the office team during the virtual ward round. Virtual ward rounds using smartphones can facilitate remote communication between staff, students and patients. Staff in isolation or shielding can also assist front line colleagues from home. Smarter use of the smart phone may help reduce staff numbers on wards and reduce the number COVID-19 and nosocomial infections, potentially reducing morbidity and mortality locally and globally.

RESUMO

In this paper, we have given the design and development of a new wearable device that assists visually impaired individuals to travel independently and confidently. The newly proposed device is based on range-based sensors and would work effectively in both indoor and outdoor conditions. It is constructed in the form of two separate modules; one module is designed such that it can be attached to the waist belt of the user, and the other module is designed to wear it on ankle of the user. Both the modules communicate with each other using wireless communication and can cover the full front environment of the user. The information about the front environment is transmitted to the user, via headphone, by sending a set of voice instructions, stored in a memory card added in the belt module. In order to use the device in crowd mode, appropriate networking techniques were also implemented in the prototype such that the interference of two or more devices in the close vicinity can be avoided. In the end, effectiveness of the device is analyzed and proved by conducting experiments and obtaining statistical results.

RESUMO

BACKGROUND: Japanese encephalitis (JE) occurs in fewer than 1% of JE virus (JEV) infections, often with catastrophic sequelae including death and neuropsychiatric disability. JEV transmission in Pakistan was documented in 1980s and 1990s, but recent evidence is lacking. Our objective was to investigate JEV as a cause of acute encephalitis in Pakistan. METHODS: Persons aged ≥1 month with possible JE admitted to two acute care hospitals in Karachi, Pakistan from April 2015 to January 2018 were enrolled. Cerebrospinal fluid (CSF) or serum samples were tested for JEV immunoglobulin M (IgM) using the InBios JE DetectTM assay. Positive or equivocal samples had confirmatory testing using plaque reduction neutralization tests. RESULTS: Among 227 patients, testing was performed on CSF in 174 (77%) and on serum in 53 (23%) patients. Six of eight patient samples positive or equivocal for JEV IgM had sufficient volume for confirmatory testing. One patient had evidence of recent West Nile virus (WNV) neurologic infection based on CSF testing. One patient each had recent dengue virus (DENV) infection and WNV infection based on serum results. Recent flavivirus infections were identified in two persons, one each based on CSF and serum results. Specific flaviviruses could not be identified due to serologic cross-reactivity. For the sixth person, JEV neutralizing antibodies were confirmed in CSF but there was insufficient volume for further testing. CONCLUSIONS: Hospital-based JE surveillance in Karachi, Pakistan could not confirm or exclude local JEV transmission. Nonetheless, Pakistan remains at risk for JE due to presence of the mosquito vector, amplifying hosts, and rice irrigation. Laboratory surveillance for JE should continue among persons with acute encephalitis. However, in view of serological cross-reactivity, confirmatory testing of JE IgM positive samples at a reference laboratory is essential.

RESUMO

There are few therapeutic options available for the treatment of recurrent meningiomas that have failed treatment with surgery and external-beam radiation therapy (EBRT). As additional EBRT is clinically risky, brachytherapy offers an important alternative for optimizing local control. In skull base meningiomas, the endoscopic endonasal approach (EEA) has demonstrated an excellent extent of resection. However, in the case of recurrent, atypical, or residual meningiomas, the EEA alone may not be adequate to address microscopic, residual, highly proliferative disease. In this situation, local radioactive seed brachytherapy has been shown to improve control, but few reports of this technique exist. A 48-year-old right-handed man presented on multiple occasions with recurrence of an anaplastic skull base meningioma, after multiple prior gross-total resections and multiple rounds of radiotherapy had failed. The authors performed a maximally safe neurosurgical tumor resection via EEA supplemented by the intraoperative implantation of 131Cs low-dose permanent brachytherapy seeds. They describe a technique for permanent implantation of brachytherapy seeds and provide operative video of this technique. The authors submit that utilizing this technique in combination with EEA tumor resection renders a minimally invasive approach to improving local control in a patient with a recurrent anaplastic or atypical meningioma of the skull base.

RESUMO

Pakistani women suffer the highest rate of maternal mortality in South Asia. A lack of comprehensive knowledge about maternal and newborn health (MNH) services costs impedes policy decisions to maximize the benefit from existing, as well as emerging, MNH interventions in Pakistan. We compared MNH service costs at different levels of care. A cross-sectional survey was conducted during January to March 2016 as part of a large economic evaluation in Sindh, Pakistan. Health providers and facilities were selected from a sampling frame, inclusive of public and private sectors. This study utilized a broad perspective (i.e. costs to the health system and patients/families). The unit costs of MNH services were determined through a simultaneous allocation method in the public facilities; and patient billing department in the private facilities. Descriptive analysis was performed, and an analysis of variance (ANOVA) test was applied to compare overall mean costs both within and between health facilities. A total of 31 eligible health providers and facilities (n = 25 in private; n = 7 in public) were included in the final analysis. An ambulatory visit (AV) for routine antenatal care (ANC) costs $3.6 and $0.9 at secondary- and tertiary-level public facilities, respectively. In the private sector, the costs of an AV for ANC were slightly less ($2.8) at secondary-level and much higher ($6) at tertiary-level facilities compared to the public sector. Diagnostic test costs were much higher in private facilities. The average costs of inpatient admissions were $30.5 at general ward (GW), and $151 at the intensive care unit (ICU) in public facilities. In-patient admissions costs were lower such as $9.3 at GW and $36.5 at ICU in private facilities. Understanding cost is critical to guide decisions of resource allocation within the public sector; and risk mitigation for excessive OOP costs through third party payer for services in the private sector.

RESUMO

OBJECTIVE: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy. METHODS: From January 2011 to December 2016, 763 patients underwent aortic valve replacement with bioprostheses; of these, 139 received a Perceval S sutureless valve (Group A) and 624 received a Perimount Magna Ease valve (Group B). These groups were further divided into A1 (isolated Perceval AVR), A2 (Perceval AVR with coronary artery bypass grafting [CABG]), B1 (isolated conventional stented bioprosthesis), and B2 (conventional stented bioprosthesis + CABG). RESULTS: Patients in Group A were older (mean 74 years vs. 71 years; P<0.0001), predominantly women (53% vs. 32%; P<0.0001), had a higher logistic EuroSCORE (3.26 vs. 2.43; P<0.001), more preoperative atrial fibrillation (20% vs. 13%; P=0.03), and had a lower reopening rate for bleeding (2.1% vs. 6.7%; P=0.04). Compared to Group B1, Group A1 had shorter cross-clamp (mean 40 min vs. 57 min; P≤0.0001) and bypass times (mean 63 min vs. mean 80 min; P=0.02), and they bled less postoperatively (mean 295 ml vs. mean 393 ml; P=0.002). The mean gradient across Perceval valve was 12.5 mmHg while its effective orifice area was 1.5 cm2. CONCLUSION: In our retrospective study of 763 patients, sutureless valve group patients are older, mostly women, more symptomatic preoperatively, and have higher logistic EuroSCORE. They have shorter cross-clamp and bypass times, less postoperative bleeding, and reduced incidence of reopening. Further studies are needed to evaluate the clinical benefits in short, mid, and long-terms.

RESUMO

INTRODUCTION: The incidence of postoperative thrombocytopenia after aortic valve replacement (AVR) with the Perceval S Sutureless bioprosthesis remains unclear. The aim of this study was to report thrombocytopenia associated with the use of sutureless AVR. METHODS: The data was collected retrospectively for patients who had isolated AVR with sutureless Perceval S valve (Group A: 72 patients) and was compared with patients who underwent isolated sutured AVR with Perimount Magna Ease Bioprosthesis (Group B: 101 patients) in our institution between June 2014 and January 2017. RESULTS: Cardiopulmonary bypass and cross-clamp time were significantly shorter in group A. Maximum drop in platelet count was 58% mean (day 2.3) in group A versus 44% mean (day 1.7) in group B (P=0.0001). Absolute platelet count on postoperative day 1-6 in group A was significantly less than in group B (P≤0.05). Platelet count recovered to preoperative value in 44% patients in group B versus only in 26% patients in group A at discharge (P=0.018). Moderate thrombocytopenia occurs more often in group A (41% vs. 26%) (P=0.008) while severe thrombocytopenia (<50 x 109) was observed in 6% in group A but never in group B. Platelets (P=0.007) and packed red blood cells (P=0.009) transfusion was significantly higher in the group A. CONCLUSION: The implantation of sutureless Perceval aortic valves was associated with a significant drop in platelet count postoperatively with slow recovery and higher platelets and packed red blood cells transfusion requirements. A prospective randomised trial is needed to confirm our findings.

RESUMO

OBJECTIVE: The aim of this retrospective study is to evaluate the safety and performance of the Perceval sutureless valve in patients undergoing aortic valve replacement. We report the 30-day clinical outcomes of 139 patients. METHODS: From January 2014 to December 2016, 139 patients underwent sutureless aortic valve replacement. Their operation notes, National Adult Cardiac Surgery Database and perioperative transoesophageal echocardiography findings were studied retrospectively. RESULTS: Ninety-two patients underwent isolated aortic valve replacement (group A) with Perceval valve and 47 patients had combined procedures of aortic valve replacement and coronary artery bypass grafting (group B). The patients received a size S (n=23), M (n=39), L (n=42) or XL (n=35) prosthesis. Perceval valve was successfully implanted in 135 (97.1%) patients. Mean cross-clamping time and bypass time were 40 and 63 minutes for isolated cases, while 68 and 107 minutes for combined cases. Three (2.1%) patients died within 30 days. Four patients suffered stroke and 5 patients went into acute renal failure. Median intensive care unit and hospital stay was 2 and 8.5, respectively. Four valves were explanted due to significant paravalvular leak after surgery. Five patients had permanent pacemaker as a result of complete heart block and mean postoperative drainage was 295 mL for isolated case and 457 mL for combined cases. The mean gradient across Perceval valve was 12.5 mmHg while its effective orifice area was 1.5 cm2. CONCLUSION: Early postoperative results showed that Perceval valve is safe. Further follow up is needed to evaluate the long-term outcome with this bioprosthesis.

Results: Ninety-two patients underwent isolated aortic valve replacement (group A) with Perceval valve and 47 patients had combined procedures of aortic valve replacement and coronary artery bypass grafting (group B). The patients received a size S (n=23), M (n=39), L (n=42) or XL (n=35) prosthesis. Perceval valve was successfully implanted in 135 (97.1%) patients. Mean cross-clamping time and bypass time were 40 and 63 minutes for isolated cases, while 68 and 107 minutes for combined cases. Three (2.1%) patients died within 30 days. Four patients suffered stroke and 5 patients went into acute renal failure. Median intensive care unit and hospital stay was 2 and 8.5, respectively. Four valves were explanted due to significant paravalvular leak after surgery. Five patients had permanent pacemaker as a result of complete heart block and mean postoperative drainage was 295 mL for isolated case and 457 mL for combined cases. The mean gradient across Perceval valve was 12.5 mmHg while its effective orifice area was 1.5 cm2. Conclusion: Early postoperative results showed that Perceval valve is safe. Further follow up is needed to evaluate the long-term outcome with this bioprosthesis.

RESUMO

BACKGROUND: Understanding cost-drivers and estimating societal costs are important challenges for economic evaluation of health technologies in low- and middle-income countries (LMICs). This study assessed community experiences of health resource usage and perceived cost-drivers from a societal perspective to inform the design of an economic model for the Community Level Interventions for Pre-eclampsia (CLIP) trials. METHODS: Qualitative research was undertaken alongside the CLIP trial in two districts of Sindh province, Pakistan. Nine focus groups were conducted with a wide range of stakeholders, including pregnant women, mothers-in-law, husbands, fathers-in-law, healthcare providers at community and health facility-levels, and health decision/policy makers at district-level. The societal perspective included out-of-pocket (OOP), health system, and program implementation costs related to CLIP. Thematic analysis was performed using NVivo software. RESULTS: Most pregnant women and male decision makers reported a large burden of OOP costs for in- and out-patient care, informal care from traditional healers, self-medication, childbirth, newborn care, transport to health facility, and missed wages by caretakers. Many healthcare providers identified health system costs associated with human resources for hypertension risk assessment, transport, and communication about patient referrals. Health decision/policy makers recognized program implementation costs (such as the mobile health infrastructure, staff training, and monitoring/supervision) as major investments for the health system. CONCLUSIONS: Our investigation of care-seeking practices revealed financial implications for families of pregnant women, and program implementation costs for the health system. The societal perspective provided comprehensive knowledge of cost drivers to guide an economic appraisal of the CLIP trial in Sindh, Pakistan.

RESUMO

BACKGOUND: A higher incidence of neonatal tetanus implies failure of the vaccination program in Pakistan. OBJECTIVES: The objective of this study was to assess knowledge, attitudes and practices related to tetanus toxoid (TT) vaccine in women of childbearing age. METHODS: We performed a cross-sectional survey in peri-urban Karachi, Pakistan, among women of childbearing age, stratified into three mutually exclusive groups as: married pregnant; married non-pregnant; and unmarried. Descriptive and inferential analyses were performed to estimate vaccine coverage and knowledge attributes. RESULTS: A total of 450 women participated, of which the largest proportion were married and non-pregnant (n = 185/450, 41%). Over 50% of women (n = 258/450) had not received TT vaccine. Most unmarried women (n = 139, 97%) were unvaccinated. Non-vaccination predictors included: women aged <25 years without any formal education (adjusted odds ratio [OR], 2.1; 95% confidence interval [CI], 1.0-4.4), lack of knowledge about free vaccination (adjusted OR, 4.0; 95% CI, 1.64-10.20), poor knowledge of tetanus disease/vaccination (adjusted OR, 4.6; 95%, 2.2-9.6), living with extended family (adjusted OR, 2.0; 95% CI, 1.04-3.96); family non-supporting vaccination (adjusted OR, 5.7; 95% CI, 2.3-13.9); and husband/other family member deciding upon issues related to women's health (adjusted OR, 2.9; 95% CI, 1.3-6.6). CONCLUSION: Low coverage of TT vaccine is largely influenced by poor knowledge, family structure and family decision-making in the local communities of Pakistan.

RESUMO

BACKGROUND: Maternal mortality ratio is 276 per 100,000 live births in Pakistan. Eclampsia is responsible for one in every ten maternal deaths despite the fact that management of this disease is inexpensive and has been available for decades. Many studies have shown that health care providers in low and middle-income countries have limited training to manage patients with eclampsia. Hence, we aimed to explore the knowledge of different cadres of health care providers regarding aetiology, diagnosis and treatment of pre-eclampsia and eclampsia and current management practices. METHODS: We conducted a mixed method study in the districts of Hyderabad and Matiari in Sindh province, Pakistan. Focus group discussions and interviews were conducted with community health care providers, which included Lady Health Workers and their supervisors; traditional birth attendants and facility care providers. In total seven focus groups and 26 interviews were conducted. NVivo 10 was used for analysis and emerging themes and sub-themes were drawn. RESULTS: All participants were providing care for pregnant women for more than a decade except one traditional birth attendant and two doctors. The most common cause of pre-eclampsia mentioned by community health care providers was stress of daily life: the burden of care giving, physical workload, short birth spacing and financial constraints. All health care provider groups except traditional birth attendants correctly identified the signs, symptoms, and complications of pre-eclampsia and eclampsia and were referring such women to tertiary health facilities. Only doctors were aware that magnesium sulphate is recommended for eclampsia management and prevention; however, they expressed fears regarding its use at first and secondary level health facilities. CONCLUSION: This study found several gaps in knowledge regarding aetiology, diagnosis and treatment of pre-eclampsia among health care providers in Sindh. Findings suggest that lesser knowledge regarding management of pre-eclampsia is due to lack of refresher trainings and written guidelines for management of pre-eclampsia and presentation of fewer pre-eclamptic patients at first and secondary level health care facilities. We suggest to include management of pre-eclampsia in regular trainings of health care providers and to provide management protocols at all health facilities. TRIAL REGISTRATION: NCT01911494.
