Effects of Changes in ICU Bed Supply on ICU Utilization.

ABSTRACT: BACKGROUND:The availability of intensive care unit (ICU) beds may influence the demand for critical care. Although small studies support a model of supply-induced demand in the ICU, there is a paucity of system-wide data. OBJECTIVE:The objective of this study was to determine the relationship between ICU bed supply and ICU admission in United States hospitals. RESEARCH DESIGN:Retrospective cohort study using all-payer inpatient records from Florida, Massachusetts, New Jersey, New York, and Washington from 2010 to 2012, linked to hospital data from Medicare's Healthcare Cost Reporting Information System. SUBJECTS:Three patient groups with a low likelihood of benefiting from ICU admission-low severity patients with acute myocardial infarction and pulmonary embolism; and high severity patients with metastatic cancer at the end of life. MEASURES:We compared the risk-adjusted probability of ICU admission at hospitals that increased their ICU bed supply over time to matched hospitals that did not, using a difference-in-differences approach. RESULTS:For patients with acute myocardial infarction, ICU supply increases were associated with an increase in the probability of ICU admission that diminished over time. For patients with pulmonary embolism, there was a trend toward an association between change in ICU supply and ICU admission that did not meet statistical significance. For patients with metastatic cancer, admission to hospitals with an increasing ICU supply was not associated with changes in the probability of ICU admission. CONCLUSIONS:Increases in ICU bed supply were associated with inconsistent changes in the probability of ICU admission that varied across patient subgroups.

Project description:ObjectivesGiven finite ICU bed capacity, knowledge of ICU bed utilization during the coronavirus disease 2019 pandemic is critical to ensure future strategies for resource allocation and utilization. We sought to examine ICU census trends in relation to ICU bed capacity during the rapid increase in severe coronavirus disease 2019 cases early during the pandemic.DesignObservational cohort study.SettingThirteen geographically dispersed academic medical centers in the United States.Patients/subjectsWe obtained daily ICU censuses from March 26 to June 30, 2020, as well as prepandemic ICU bed capacities. The primary outcome was daily census of ICU patients stratified by coronavirus disease 2019 and mechanical ventilation status in relation to ICU capacity.InterventionsNone.Measurements and main resultsPrepandemic overall ICU capacity ranged from 62 to 225 beds (median 109). During the study period, the median daily coronavirus disease 2019 ICU census per hospital ranged from 1 to 84 patients, and the daily ICU census exceeded overall ICU capacity for at least 1 day at five institutions. The number of critically ill patients exceeded ICU capacity for a median (interquartile range) of 17 (12-50) of 97 days at these five sites. All 13 institutions experienced decreases in their noncoronavirus disease ICU population, whereas local coronavirus disease 2019 cases increased. Coronavirus disease 2019 patients reached their greatest proportion of ICU capacity on April 12, 2020, when they accounted for 44% of ICU patients across all participating hospitals. Maximum ICU census ranged from 52% to 289% of overall ICU capacity, with three sites less than 80%, four sites 80-100%, five sites 100-128%, and one site 289%.ConclusionsFrom March to June 2020, the coronavirus disease 2019 pandemic led to ICU censuses greater than ICU bed capacity at fives of 13 institutions evaluated. These findings demonstrate the short-term adaptability of U.S. healthcare institutions in redirecting limited resources to accommodate a public health emergency.

Project description:BackgroundDemand for Physiotherapy is on the rise due to increasing ageing population and consequent disability and morbidity. However, the costs of healthcare in developing countries are rising, and healthcare resources are limited making the supply of Physiotherapy services challenging in rural communities. Availability of Physiotherapy may help to reduce the burden of disability and enhance efficiency of healthcare systems. This study investigated the characteristics and associations of utilization and supply of community Physiotherapy in Nigeria.MethodsCross-sectional survey of 336 consenting community dwelling individuals from three selected communities in Nigeria was carried out. A three-section validated self-developed questionnaire which sought information on socio-demographics, utilization and supply of community Physiotherapy, as well as how to improve community Physiotherapy services was used. A household was used as the primary sampling unit in the study. Inferential and Descriptive statistics were used to assess the data.ResultsLifetime, 12-month and point utilization of physiotherapy was 21.7, 7.4 and 2.7% respectively. Physiotherapy utilization was significantly associated with level of education (p = 0.007), belief on pain as "spiritual" (p = 0.020) and religious belief (p = 0.001). The respondents with primary, secondary and tertiary education were 14.3, 13.9 and 26 times more likely to utilize physiotherapy services, respectively. Those who 'agree' or were 'not sure' that their religious belief was against physiotherapy were 92 and 83% less likely to utilize physiotherapy services, respectively compared with those who 'disagree'. Availability and supply of Physiotherapy services were mostly at the township teaching hospital (47.9%) and private hospitals (20.5%). The supply of Physiotherapy services within the communities was mostly on temporary basis (24.7%) and through visiting Physiotherapists (21.4%). Physiotherapy services utilized was mainly exercise (46.6%) and soft tissue mobilization (41.1%). Travel costs (32.6%), time constraints (27.9%) and work commitments (24.8%) were the constraints for Physiotherapy utilization while positive beliefs and higher education improved Physiotherapy utilization.ConclusionsUtilization and supply of Physiotherapy services in Nigerian rural community was low. Low utilization of Physiotherapy services in Nigerian rural communities were most significantly influenced by low educational status and beliefs about pain.

Project description:Background/methodsQualitative studies suggest that bed nets affect the thermal comfort of users. To understand and reduce this discomfort the effect of bed nets on temperature, humidity, and airflow was measured in rural homes in Asia and Africa, as well as in an experimental wind tunnel. Two investigators with architectural training selected 60 houses in The Gambia, Tanzania, Philippines, and Thailand. Data-loggers were used to measure indoor temperatures in hourly intervals over a 12 months period. In a subgroup of 20 houses airflow, temperature and humidity were measured at five-minute intervals for one night from 21.00 to 6.00 hrs inside and outside of bed nets using sensors and omni-directional thermo-anemometers. An investigator set up a bed net with a mesh size of 220 holes per inch 2 in each study household and slept under the bed net to simulate a realistic environment. The attenuation of airflow caused by bed nets of different mesh sizes was also measured in an experimental wind tunnel.ResultsThe highest indoor temperatures (49.0 C) were measured in The Gambia. During the hottest months of the year the mean temperature at night (9 pm) was between 33.1 C (The Gambia) and 26.2 C (Thailand). The bed net attenuated the airflow from a minimum of 27% (Philippines) to a maximum of 71% (The Gambia). Overall the bed nets reduced airflow compared to un-attenuated airflow from 9 to 4 cm sec-1 or 52% (p<0.001). In all sites, no statistically significant difference in temperature or humidity was detected between the inside and outside of the bed net. Wind tunnel experiments with 11 different mesh-sized bed nets showed an overall reduction in airflow of 64% (range 55 - 71%) compared to un-attenuated airflow. As expected, airflow decreased with increasing net mesh size. Nets with a mesh of 136 holes inch-2 reduced airflow by 55% (mean; range 51 - 73%). A denser net (200 holes inch-2) attenuated airflow by 59% (mean; range 56 - 74%).DiscussionDespite concerted efforts to increase the uptake of this intervention in many areas uptake remains poor. Bed nets reduce airflow, but have no influence on temperature and humidity. The discomfort associated with bed nets is likely to be most intolerable during the hottest and most humid period of the year, which frequently coincides with the peak of malaria vector densities and the force of pathogen transmission.ConclusionsThese observations suggest thermal discomfort is a factor limiting bed net use and open a range of architectural possibilities to overcome this limitation.

Project description:BackgroundDriven by the government's firm commitment to promoting maternal health, maternal mortality ratio (MMR) in China has achieved a remarkable reduction over the past 25 years. Paralleled with the decline of MMR has been the expansion of hospital bed supply as well as substantial reduction in hospital bed distribution inequalities, which were thought to be significant contributors to the reduction in MMR. However, evidences on the impact of hospital bed supply as well as how its distribution inequality has affected MMR remains scarce in China. Addressing this uncertainty is essential to understand whether efforts made on the expansion of healthcare resource supply as well as on improving its distribution inequality from a geographical perspective has the potential to produce measurable population health improvements.MethodsPanel data of 31 provinces in China between 2004 and 2016 were extracted from the national statistical data, including China Statistical Yearbooks, China Health Statistical Yearbooks and other national publications. We firstly described the changes in hospital bed density as well as its distribution inequality from a geographical perspective. Then, a linear mixed model was employed to evaluate the impact of hospital bed supply as well as its distribution inequality on MMR at the provincial level.ResultsThe MMR decreased substantially from 48.3 to 19.9 deaths per 100,000 live births between 2004 and 2016. The average hospital bed density increased from 2.28 per 1000 population in 2004 to 4.54 per 1000 population in 2016, with the average Gini coefficient reducing from 0.32 to 0.25. As indicated by the adjusted mixed-effects regressions, hospital bed density had a negative association with MMR (β = - 0.112, 95% CI: - 0.210--0.013) while every 0.1-unit reduction of Gini coefficient suggested 14.50% decline in MMR on average (β = 1.354, 95% CI: 0.123-2.584). Based on the mediation analysis, the association between hospital bed density or Gini coefficient with MMR was found to be significantly mediated by facility birth rate, especially during the period from 2004 to 2009.ConclusionsThis study provided empirical evidences on China's impressive success in the aspect of reducing MMR which could be attributed to the expansion of hospital beds as well as the improvement in its distribution inequality from a geographical perspective. Such findings were expected to provide evidence-based implications for long-term policy-making procedures in order to achieve rational healthcare resource allocations as well as promoting the equity and accessibility to obtaining health care from a holistic perspective. Constant efforts should be made on improving the equity in healthcare resource allocations in order to achieve the penetration of universal healthcare coverage.
