Disparities in women's health and health care experiences in the United States and Israel: findings from 1998 National Women's Health Surveys

Incidence and predictors of critical events during urgent air-medical transport

BACKGROUND

Little is known about the risks of urgent air-medical transport used in regionalized health care systems. We sought to determine the incidence of in-transit critical events and identify factors associated with these events.

METHODS

We conducted a population-based, retrospective cohort study using clinical and administrative data. We included all adults undergoing urgent air-medical transport in the Canadian province of Ontario between Jan. 1, 2004, and May 31, 2006. The primary outcome was in-transit critical events, which we defined as death, major resuscitative procedure, hemodynamic deterioration, or inadvertent extubation or respiratory arrest.

RESULTS

We identified 19 228 patients who underwent air-medical transport during the study period. In-transit critical events were observed in 5.1% of all transports, for a rate of 1 event per 12.6 hours of transit time. Events consisted primarily of new hypotension or airway management procedures. Independent predictors of critical events included female sex (adjusted odds ratio [OR] 1.3, 95% confidence interval [CI] 1.1-1.5), assisted ventilation before transport (adjusted OR 3.0, 95% CI 2.3-3.7), hemodynamic instability before transport (adjusted OR 3.2, 95% CI 2.5-4.1), transport in a fixed-wing aircraft (adjusted OR 1.5, 95% CI 1.2-1.8), increased duration of transport (adjusted OR 1.02 per 10-minute increment, 95% CI 1.01-1.03), on-scene calls (adjusted OR 1.7, 95% CI 1.4-2.1) and type of crew (adjusted OR 0.6 for advanced care paramedics v. critical care paramedics, 95% CI 0.5-0.7).

INTERPRETATION

Critical events occurred in about 1 in every 20 air-medical transports and were associated with multiple risk factors at the patient, transport and system levels. These findings have implications for the refinement of training of paramedic transport crews and processes for triage and transport.

Is universal coverage a solution for disparities in health care? Findings from three low-income provinces of Thailand

The policy on universal coverage (UC) of health care has been adopted and implemented incrementally by the government of Thailand since April 2001 with the aim of providing the access to care for the uninsured population. The success of UC, however, depends on how effective its design and implementation arrangements are in reaching population and affecting households' health seeking behavior and abilities to take up benefits of UC. The results from the household survey of 1834 respondents conducted in three low-income provinces (Tak, Sakol Nakorn, Narathiwat) show that the Gold card with exemption scheme was pro-poor while other insurance schemes tended to favor the rich with 2.6% of respondents reported having more than one type of health insurance coverage and 8.9% without health insurance. The insurance status had statistically significant association with health care use, and knowledge on family planning method and sexually transmitted diseases. Additionally, consumer preferences and socioeconomics factors are a key to disparities in health care utilization.

Perceived need and receipt of outpatient mental health services. Factors affecting access in Israeli HMOs

The finance and provision of care have been suggested as variables that affect the utilization of mental health services. This study compared perceived need and receipt of outpatient mental health services in a staff-model health maintenance organization (HMO) and in three HMOs with preferred provider organization (PPO) arrangements. A national random phone survey (n = 1,394) of perceived need for and receipt of mental health assistance was conducted in Israel in 1995. Health care is provided by four HMOs that differ in mental health benefits, utilization management (i.e., prior authorization and referral requirements), and availability of mental health services (i.e., pool of providers and geographic dispersal). About one-quarter of the respondents had perceived a need for help at some time in their life. Significantly fewer respondents from the HMO with a small pool of providers got help (20%) than respondents from the other HMOs, which had almost identical rates of obtaining care (40.3%, 37.3% and 40.3%). Providing generous outpatient mental health care benefits does not appear to increase the proportion of persons in need who get help. However, severely limiting the availability of services does reduce the proportion of persons getting care. Implications for regulating insurers are discussed.
