COVID-19 Pandemic Planning: Simulation Models to Predict Biochemistry Test Capacity for Patient Surges.

BACKGROUND: Patient surges beyond hospital capacity during the initial phase of the COVID-19 pandemic emphasized a need for clinical laboratories to prepare test processes to support future patient care. The objective of this study was to determine if current instrumentation in local hospital laboratories can accommodate the anticipated workload from COVID-19 infected patients in hospitals and a proposed field hospital in addition to testing for non-infected patients. METHODS: Simulation models predicted instrument throughput and turn-around-time for chemistry, ion-selective-electrode, and immunoassay tests using vendor-developed software with different workload scenarios. The expanded workload included tests from anticipated COVID patients in 2 local hospitals and a proposed field hospital with a COVID-specific test menu in addition to the pre-pandemic workload. RESULTS: Instrumentation throughput and turn-around time at each site was predicted. With additional COVID-patient beds in each hospital, the maximum throughput was approached with no impact on turnaround time. Addition of the field hospital workload led to significantly increased test turnaround times at each site. CONCLUSIONS: Simulation models depicted the analytic capacity and turn-around times for laboratory tests at each site and identified the laboratory best suited for field hospital laboratory support during the pandemic.

Moving in for Renovations: An Innovative Solution for Replacing End-of-Life Capital Equipment. The Michael Garron Hospital-Sunnybrook Collaborative Catheterization Laboratory Project.

Replacement of an end-of-life cardiac catheterization laboratory ("cath lab") can pose a significant challenge to a hospital, particularly in single-cath-lab institutions. The disruption in patient care requires innovative approaches to minimize the inconvenience and ensure ongoing quality of care. We describe a unique approach whereby Michael Garron Hospital (MGH) "leased" a cath lab within Sunnybrook Health Sciences Centre for a 12-week period during a cath lab replacement project at MGH. The MGH cath lab and patient recovery bay remained a completely separate entity staffed by MGH nurses and physicians, with electronic connection to the home hospital. A total of 420 patients underwent cardiac catheterization with no adverse outcomes while maintaining system efficiency and high patient and staff satisfaction. Cath lab leasing involving two cooperating hospitals is an innovative and safe way to bridge a cath lab replacement.

Is laboratory medicine ready for the era of personalized medicine? A survey addressed to laboratory directors of hospitals/academic schools of medicine in Europe.

Developments in "-omics" are creating a paradigm shift in laboratory medicine leading to personalized medicine. This allows the increase in diagnostics and therapeutics focused on individuals rather than populations. In order to investigate whether laboratory medicine is ready to play a key role in the integration of personalized medicine in routine health care and set the state-of-the-art knowledge about personalized medicine and laboratory medicine in Europe, a questionnaire was constructed under the auspices of the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) and the European Society of Pharmacogenomics and Personalised Therapy (ESPT). The answers of the participating laboratory medicine professionals indicate that they are aware that personalized medicine can represent a new and promising health model, and that laboratory medicine should play a key role in supporting the implementation of personalized medicine in the clinical setting. Participants think that the current organization of laboratory medicine needs additional/relevant implementations such as (i) new technological facilities in -omics; (ii) additional training for the current personnel focused on the new methodologies; (iii) incorporation in the laboratory of new competencies in data interpretation and counseling; and (iv) cooperation and collaboration among professionals of different disciplines to integrate information according to a personalized medicine approach.

Survey about the use of lung function testing in public hospitals in Catalonia in 2009.

BACKGROUND: Underdiagnosis is one of the problems with the greatest impact on respiratory disease management and requires specific interventions. Access to quality spirometry is especially important and is an objective of the Master Plan for Respiratory Diseases of the Department of Health of the Generalitat de Catalunya. OBJECTIVE: To determine the current use of spirometry at public hospitals in Catalonia, possible deficiencies and options for improvement. METHODS: A cross-sectional survey of 65 public hospitals in Catalonia in 2009. Descriptive analyses were developed for each public health-care region. RESULTS: A lack of uniformity was observed in the use of spirometry at the regional level (between 0,98 and 1.50 spirometries per 100 inhabitants). We identified two factors associated with a higher rate of spirometry: i) the existence of a Respiratory Medicine Department at the hospital, and ii) the existence of a set location to carry out spirometries. Several areas for improvement also were identified: quality control of the test itself, the inclusion of spirometry in electronic health-care records and continuing education programs. CONCLUSIONS: The results of this study have identified areas for improvement in spirometry programs.

A percutaneous coronary intervention lab in every hospital?

BACKGROUND: In 2001, 1176 US hospitals were capable of performing primary percutaneous coronary intervention (PCI), and 79% of the population lived within 60-minute ground transport of these hospitals. We compared these estimates with data from 2006 to explore how hospital PCI capability and population access have changed over time. METHODS AND RESULTS: We estimated the proportion of the population 18 years of age or older, living in 2006 within a 60-minute drive of a PCI-capable hospital, and we compared our estimate with a previously published report on 2001 data. Over the 5-year period, the number of PCI-capable hospitals grew from 1176 to 1695 hospitals, a relative increase of 44%; access to the procedure grew from 79.0% to 79.9% of the population, a relative increase of 1%. CONCLUSIONS: Our data indicate a large increase in the number of hospitals capable of performing PCI from 2001 to 2006, but this increase was not associated with an appreciable change in the proportion of the population with access to the procedure. In the future, more attention is needed on changes in PCI capacity over time and on the effects of these changes on outcomes of interest such as service utilization, expenditures, patient outcomes, and population health.

Against all odds: diagnosing tuberculosis in South Africa.

Clinical and logistic systems to support the timely diagnosis of tuberculosis are currently not preventing large numbers of tuberculosis deaths in South Africa. Context-appropriate systems for the diagnosis of tuberculosis are entirely dependent on effective and responsive management of human resources and an uninterrupted supply of clinical materials. Attention to these components of the tuberculosis program is urgently needed before new diagnostic technologies can be expected to impact on tuberculosis mortality in resource constrained settings.

Challenges in the organisation of a microsurgery laboratory in a low resource country.

OBJECTIVES: To highlight the problems encountered in the set up, organisation and operations of a microsurgery laboratory in a low resource tertiary care hospital in Lagos, Nigeria. METHODS: The basic infrastructural deficiencies of this setting were encountered. Significant administrative, logistic and technical obstacles needed to be overcome. The need for improvisation and flexibility in the organisation and operations of such a laboratory is highlighted. The use of locally available, cheaper variety of instruments and consumables in the microsurgery laboratories of developing countries with limited resources was demonstrated by our experience . CONCLUSION: We conclude that even in the setting of low resource tertiary centres found in many developing countries, challenges could be overcome and standard acceptable patency rates obtained in the microsurgery laboratory .

[Current infectious disease care in Spain]. / La asistencia infectológica actual en España.

Despite the specialist activity of Infectious Diseases not being officially recognised, the majority of the hospitals in the autonomous communities of Spain are equipped with structures, with significant heterogeneity among them, to be able to offer high quality care in these diseases. The main characteristics of and Infectious Diseases Department is its important healthcare activity, more than in other officially recognised medical specialities, and also its important interrelationship with other services in the hospital which is clearly horizontal healthcare. Furthermore, the aforementioned infectious disease care units have developed important activities in the arena of community and public health and, in collaboration with health authorities, contribute to the rational use of antimicrobials and the relationship with Primary Care. The future of specialists in infectious diseases, when they are officially recognised, will be the creation of clinical management units in every health institution with the objective of coordinating all the specialised health care, both in the hospital environment and in its health area of influence.

Antiretroviral treatment in resource-poor settings: what can we learn from the existing programmes in Thailand?

Here we review a number of issues of relevance to the scale-up of antiretroviral therapy in Thailand. Thailand has an estimated number of people living with HIV/AIDS of approximately 600,000. Currently less than 10% of those are receiving highly active antiretroviral therapy. Government commitment to increase the numbers of individuals being treated has increased because of advocacy from various sectors of society, most importantly from organizations of individuals living with HIV/AIDS, decreasing antiretroviral drug prices, the availability of external funds, and the example of successful treatment initiatives by non-governmental organizations, academia and the private sector. It has also been prompted by the hosting of the 2004 International AIDS Conference in Bangkok.

Situation of laboratory service and instruments in Thailand: a descriptive study from questionnaires.

Laboratory instruments are one of the main items in laboratory investment. To establish data for the situation of laboratory service and instruments in Thailand, questionnaires were randomly sent to one hundred and twenty laboratories. Sixty-three filled questionnaires from eleven university and affiliated hospitals, thirty-four government hospitals, and eighteen private hospital laboratories were sent back to the authors to be analyzed. Only the number of samples and instruments used during office hours were analyzed in this study by descriptive method. From the data it was found that the average number of personnel and tests of the university and affiliated hospital laboratories was the highest. To analyze the efficiency of the instruments used in the laboratories, the authors compared the average service number of samples or tests to the average number of samples or tests that was calculated from the instruments. The ratio of the average number of samples or tests that were calculated from the instruments and the average service number of samples or tests for chemistry and CBC were 2.13, 3.41, 5.24 and 2.33, 2.76, 3.71 in university and affiliated hospital laboratories, government hospital laboratories, and the private hospital laboratories, respectively. From the data, it was concluded that the instrument situation in laboratories of the university and affiliated hospitals was more appropriate than government hospital and private hospital laboratories. To improve the efficiency of using laboratory instruments, more concern must be given to the management of laboratory instruments and cooperation between hospitals could increase the efficiency of the instrument investment.

Diagnóstico del manejo de los desechos en los laboratorios clínicos de la CCSS / Diagnostic of management of the waste in the clinic laboratories of the CCSS

A 1997 document on budgetary Policies and Standards issued by Costa Rica's government-operated Soocialized Health Care System (CCSS) requires the State Health Clinics to comply with the stipulations included in the Enviroment Organic Law. Because the CCSS has focused its interest on achieving appropiate waste management, this study was conducted in order to find out the clinical laboratories perception and kowledge of the problem, types of waste, personnel training, and their employees hygiene and on-the-job safety.

Long-term outcome in acute myocardial infarction patients admitted to hospitals with and without on-site cardiac catheterization facilities. MITI Investigators. Myocardial Infarction Triage and Intervention.

BACKGROUND: Previous studies have documented the strong association between availability of on-site cardiac catheterization facilities and increased use of coronary angiography in patients with acute myocardial infarction (AMI). Although these studies have shown little influence of the availability of catheterization labs on hospital mortality, no long-term follow-up has been reported. METHODS AND RESULTS: From a cohort of 12,331 AMI patients admitted to 19 Seattle area hospitals, we compared long-term outcome in 7985 patients admitted to hospitals with and 4346 patients admitted to hospitals without on-site catheterization labs. During the index hospitalization, patients admitted to hospitals with on-site catheterization were more likely to undergo coronary angiography (67.1% versus 39.3%, P<.0001), coronary angioplasty (32.5% versus 13.2%, P<.0001), or coronary bypass surgery (12.5% versus 9.5%, P<.0001). At 3-year follow-up, patients admitted to hospitals with on-site catheterization labs were more likely to undergo postdischarge angiography (19.2% versus 15.2%, P=.0001) and coronary angioplasty (11.6% versus 8.2%, P<.0001). This was associated with approximately $2500.00 per patient in higher cumulative costs. Despite this higher rate of procedure use, there was no association between admission to a hospital with on-site catheterization facilities and lower long-term mortality (multivariate hazard ratio, 1.0; 95% CI, 0.93 to 1.1., the hazard being associated with admission to hospitals with on-site catheterization facilities). CONCLUSIONS: In an urban area with unconstrained patient transfer mechanisms and high overall cardiac procedure use rates, AMI patients admitted to hospitals without on-site catheterization facilities were managed with fewer procedures during hospitalization and follow-up. This more conservative treatment approach was not associated with any observed increase in long-term mortality.

The relationship between the supply of cardiac catheterization laboratories, cardiologists and the use of invasive cardiac procedures in northern New England.

OBJECTIVES: Utilization rates of coronary angiography and cardiac revascularization have been found to vary between areas. This study addresses the relationship between resource supply and procedure rates. METHODS: We compared the association of per capita catheterization laboratories, per capita cardiologists and multi-provider markets (where more than one hospital offers coronary angiography services) with the utilization rates for angiography and cardiac revascularization in northern New England, USA. Administrative data were used to capture invasive cardiac procedures. Small area analyses were used to create coronary angiography service areas. Linear regression methods were used to measure associations between the resource supply and utilization rates. RESULTS: Variation in the use of invasive cardiac procedures was strongly associated with the population-based availability of catheterization facilities and multi-provider markets and unrelated to cardiologist supply or need (as reflected in the hospitalization rates for myocardial infarction). In the multivariate model, an increase of 1 catheterization laboratory per 100,000 population was associated with an increase in the angiography rate of 1.62 per 1000 population; those service areas with multi-provider markets were associated with an additional increase in the angiography rate of 1.27 per 1000 population (R2 = 0.84, P = 0.0006). There was a moderately strong relationship between the catheterization laboratories per capita and the revascularization rates (R2 = 0.43, P = 0.029). Angiography rates were highly associated with cardiac revascularization rates: an increase in the angiography rate of 1 per 1000 population was associated with a 0.46 per 1000 increase in the cardiac revascularization rate (R2 = 0.85, P = 0.0001). CONCLUSIONS: Our work suggests that current efforts to address variation in cardiac procedures through activities such as appropriateness criteria, guidelines and utilization review are misdirected and should be redirected towards capacity, in this case the supply of catheterization facilities.
