Developing population health research priorities in Asian city state: Results from a multi-step participatory community engagement.

OBJECTIVES: To identify a broad range of research priorities to inform the studies seeking to improve population health outcomes based on the engagement of diverse stakeholders. METHODS: A multi-step, participatory and mixed-methods approach was adopted to solicit and structure the investigative themes from diverse stakeholders. The priority setting exercise involved four key phases: (1) feedback from community leadership; (2) interim ranking survey and focus group discussions during the population health symposium; (3) individual in-depth interviews with stakeholders in the community; and (4) synthesis of the research priorities from the multistep process. RESULTS: Diverse stakeholders in Singapore, comprising community partnership leaders, health care and social service providers, users of population health services, patients and caregivers, participated in the research priority setting exercise. Initial 14 priorities were identified from six community leadership feedback, 42 survey responses, two focus groups (n = 16) and 95 in-depth interviews. The final integrated research agenda identified six priorities: empower residents and patients to take charge of their health; improve care transition and management through relationship building and communication; enhance health-social care interface; improve respite care services for long-term caregivers; develop primary care as a driving force for care integration; and capacity building for service providers. Selected research questions in each priority area were also generated to develop novel models of care, foster collaboration, implement optimal services and enhance understanding of the end users' care needs. CONCLUSIONS: This study illuminates that greater community engagement in research priority setting for population health can facilitate the formulation of evidence-based research agendas that matter to the care providers and service users in the community. The outcomes derived from this exercise will help focus researchers' efforts through which meaningful gains can be made for population health.

Evaluation of a practical expert defined approach to patient population segmentation: a case study in Singapore.

BACKGROUND: Segmenting the population into groups that are relatively homogeneous in healthcare characteristics or needs is crucial to facilitate integrated care and resource planning. We aimed to evaluate the feasibility of segmenting the population into discrete, non-overlapping groups using a practical expert and literature driven approach. We hypothesized that this approach is feasible utilizing the electronic health record (EHR) in SingHealth. METHODS: In addition to well-defined segments of "Mostly healthy", "Serious acute illness but curable" and "End of life" segments that are also present in the Ministry of Health Singapore framework, patients with chronic diseases were segmented into "Stable chronic disease", "Complex chronic diseases without frequent hospital admissions", and "Complex chronic diseases with frequent hospital admissions". Using the electronic health record (EHR), we applied this framework to all adult patients who had a healthcare encounter in the Singapore Health Services Regional Health System in 2012. ICD-9, 10 and polyclinic codes were used to define chronic diseases with a comprehensive look-back period of 5 years. Outcomes (hospital admissions, emergency attendances, specialist outpatient clinic attendances and mortality) were analyzed for years 2012 to 2015. RESULTS: Eight hundred twenty five thousand eight hundred seventy four patients were included in this study with the majority being healthy without chronic diseases. The most common chronic disease was hypertension. Patients with "complex chronic disease" with frequent hospital admissions segment represented 0.6% of the eligible population, but accounted for the highest hospital admissions (4.33 ± 2.12 admissions; p < 0.001) and emergency attendances (ED) (3.21 ± 3.16 ED visits; p < 0.001) per patient, and a high mortality rate (16%). Patients with metastatic disease accounted for the highest specialist outpatient clinic attendances (27.48 ± 23.68 visits; p < 0.001) per patient despite their relatively shorter course of illness and high one-year mortality rate (33%). CONCLUSION: This practical segmentation framework can potentially distinguish among groups of patients, and highlighted the high disease burden of patients with chronic diseases. Further research to validate this approach of population segmentation is needed.

Severe acute respiratory syndrome in a naval diver.

Severe acute respiratory syndrome (SARS) is a highly infectious, rapidly progressive, emerging disease. Early diagnosis and preventive measures are key for treatment and minimization of secondary spread. In the context of the armed forces, aggressive containment measures are essential to prevent an outbreak. In this study, we present the first reported case, to our knowledge, of SARS in a naval diver. The special physical requirements for divers and the potential complications associated with deep sea diving necessitate extensive investigation before certification of fitness for diving after SARS. In the early recovery period, potential problems during diving are caused by inadequate lung ventilation in relation to exercise level and increased breathing resistance attributable to weak respiratory muscles, with corresponding risk of hypoxia and hypercapnia, as well as decreased ability to respond to nonrespiratory problems during diving. Problems in the late recovery period include increased risk of diving complications (such as pulmonary barotrauma) resulting from fibrosis and scarring within the lung parenchyma, which are known complications of SARS. From our experience, we suggest that computed tomographic scans of the thorax, lung function tests, and careful follow-up monitoring should play a vital role in the assessment of patients during the convalescent period, before certification of fitness to dive.

Coordination and resource maximization during disaster relief efforts.

INTRODUCTION: In the aftermath of the Earthquake and Tsunami in Southeast Asia, many relief organizations sent medical aid to affected areas. OBJECTIVE: The aim of this paper is to examine the mix of healthcare workers resulting from an influx of aid to Meulaboh, Indonesia, and how they met local healthcare needs. METHODS: Data were collected from the registration center for relief organizations in Meulaboh and daily hospital meetings on healthcare needs and available workers. RESULTS: Prior to the Tsunami, there were 14 doctors and 120 nurses in the hospital. By the third week after the Tsunami, there were 21 surgeons performing 10 surgeries daily, and >20 non-surgical doctors in the 90-bed hospital. There were <70 nurses available during the month after the Tsunami, which was insufficient for the needs of the hospital. In the town of Meulaboh, the number of doctors exceeded the number of nurses, while public health workers comprised <5% of the healthcare workers. CONCLUSION: An initial disaster-coordinating agency, formed by the United Nations (UN) in conjunction with affected countries, should link actively with relief organizations. This will optimize help in meeting local needs, and direct relief to where it is needed most.

Airway and ventilatory equipment in field anesthesia: what's new?

Advances in medical technology provide the modern day field anesthetist with the extra edge to meet the challenges faced in the harsh environment of the battlefield and enhance the survivability of casualties. The tasks of triage, resuscitation, and administration of anesthesia can be facilitated with the use of new airway devices, portable ventilators, and monitoring devices. Before such equipment is used in the field, the anesthetist must carefully weigh the advantages and disadvantages and must be cognizant of the limitations of individual devices in different environmental settings. These devices should ideally be portable, lightweight, rugged in construction, durable, easy to use (requiring minimal training and supervision), readily replaceable, and cost-effective.
