Does gatekeeping control costs for privately insured children? Findings from the 1996 medical expenditure panel survey

Effect of Having a Usual Source of Care on Medical Expenses - Using the Korea Health Panel Data

BACKGROUND

There is a controversy about the effect of having a usual source of care on medical expenses. Although many studies have shown lower medical expenses in a group with a usual source of care, some have shown higher medical expenses in such a group. This study aimed to empirically demonstrate the effect of having a usual source of care on medical expenses.

METHODS

The participants included those aged 20 years and older who responded to the questionnaire about "having a usual source of care" from the Korean Health Panel Data of 2012, 2013, and 2016 (6,120; 6,593; and 7,598 respectively). Those who responded with "I do not get sick easily" or "I rarely visit medical institutions" as the reasons for not having a usual source of care were excluded. The panel regression with random effects model was performed to analyze the effect of having a usual source of care on medical expenses.

RESULTS

The group having a usual source of care spent 20% less on inpatient expenses and 25% less on clinic expenses than the group without a usual source of care. Particularly, the group having a clinic-level usual source of care spent 12% less on total medical expenses, 9% less on outpatient expenses, 35% less on inpatient expenses, and 74% less on hospital expenses, but 29% more on clinic expenses than the group without a usual source of care.

CONCLUSION

This study confirmed that medical expenses decreased in the group with a usual source of care, especially a clinic-level usual source of care (USC), than in the group without a usual source of care. Encouraging people to have a clinic-level USC can control excessive medical expenses and induce desirable medical care utilization.

Impact of GP gatekeeping on quality of care, and health outcomes, use, and expenditure: a systematic review

BACKGROUND

GPs often act as gatekeepers, authorising patients' access to specialty care. Gatekeeping is frequently perceived as lowering health service use and health expenditure. However, there is little evidence suggesting that gatekeeping is more beneficial than direct access in terms of patient- and health-related outcomes.

AIM

To establish the impact of GP gatekeeping on quality of care, health use and expenditure, and health outcomes and patient satisfaction.

DESIGN AND SETTING

A systematic review.

METHOD

The databases MEDLINE, PreMEDLINE, Embase, and the Cochrane Library were searched for relevant articles using a search strategy. Two authors independently screened search results and assessed the quality of studies.

RESULTS

Electronic searches identified 4899 studies (after removing duplicates), of which 25 met the inclusion criteria. Gatekeeping was associated with better quality of care and appropriate referral for further hospital visits and investigation. However, one study reported unfavourable outcomes for patients with cancer under gatekeeping, and some concerns were raised about the accuracy of diagnoses made by gatekeepers. Gatekeeping resulted in fewer hospitalisations and use of specialist care, but inevitably was associated with more primary care visits. Patients were less satisfied with gatekeeping than direct-access systems.

CONCLUSION

Gatekeeping was associated with lower healthcare use and expenditure, and better quality of care, but with lower patient satisfaction. Survival rate of patients with cancer in gatekeeping schemes was significantly lower than those in direct access, although primary care gatekeeping was not otherwise associated with delayed patient referral. The long-term outcomes of gatekeeping arrangements should be carefully studied before devising new gatekeeping policies.

A qualitative study of the difficulties in reaching sustainable universal health insurance coverage in Iran

OBJECTIVE To understand the Iranian health financing system and provide lessons for policy makers about achieving universal coverage. METHODS Twenty-five interviewees from seven major health insurance companies were selected for a qualitative study in 2007. Using a semi-structured interview, three main tasks of the health financing system (revenue collection, risk pooling and purchasing) were investigated. A framework method was applied for the data analysis. RESULTS The results of the study show the following seven major obstacles to universal coverage: unknown insured rate; regressive financing and non-transparent financial flow; fragmented and non-compulsory system; non-scientifically designed benefit package; non-health-oriented and expensive payment system; uncontrolled demands; and administrative deficiency. A long-term systematic plan is required to address the above problems.

The effect of nonmedical factors on variations in the performance of colonoscopy among different health care settings

BACKGROUND

Previous published studies have shown significant variations in colonoscopy performance, even when medical factors are taken into account. This study aimed to examine the role of nonmedical factors (ie, embodied in health care system design) as possible contributors to variations in colonoscopy performance.

METHODS

Patient data from a multicenter observational study conducted between 2000 and 2002 in 21 centers in 11 western countries were used. Variability was captured through 2 performance outcomes (diagnostic yield and colonoscopy withdrawal time), jointly studied as dependent variables, using a multilevel 2-equation system.

RESULTS

Results showed that open-access systems and high-volume colonoscopy centers were independently associated with a higher likelihood of detecting significant lesions and longer withdrawal durations. Fee for service (FFS) payment was associated with shorter withdrawal durations, and so had an indirect negative impact on the diagnostic yield. Teaching centers exhibited lower detection rates and longer withdrawal times.

CONCLUSIONS

Our results suggest that gatekeeping colonoscopy is likely to miss patients with significant lesions and that developing specialized colonoscopy units is important to improve performance. Results also suggest that FFS may result in a lower quality of care in colonoscopy practice and highlight the fact that longer withdrawal times do not necessarily indicate higher quality in teaching centers.

Matching risk and resources in high-risk pregnancies

OBJECTIVE

To evaluate the joint impact of pregnancy risk and the timing of referral of high-risk pregnancies from obstetricians to maternal fetal medicine (MFM) sub-specialists on gestational age (GA) at delivery.

METHODS

For the period 1992-2002, 2567 consecutive deliveries from pregnancies of at least 23 weeks gestational age (GA) from a community-level sub-specialty perinatal center were studied. A multiple regression model was developed specifying the impact of various risk factors and referral timing.

RESULTS

Prior pregnancy risk was inversely related to GA at birth. Referral timing, operationalized as a continuous variable, did not have a significant additive impact on GA at birth, but several dummy-variable interaction effects combining risk factors and referral before 20 weeks as a dichotomy were significant.

CONCLUSION

There are identifiable risks that occur either before the pregnancy or early into it that should lead to early referral to a sub-specialist because of their impact on GA at birth. Early referral is an important tactic in a larger preterm prevention strategy, but it needs to be embedded in a broader maternal-fetal health initiative in which both generalists and sub-specialists play important roles.

Health care expenditures of immigrants in the United States: a nationally representative analysis

OBJECTIVES

We compared the health care expenditures of immigrants residing in the United States with health care expenditures of US-born persons.

METHODS

We used the 1998 Medical Expenditure Panel Survey linked to the 1996-1997 National Health Interview Survey to analyze data on 18398 US-born persons and 2843 immigrants. Using a 2-part regression model, we estimated total health care expenditures, as well as expenditures for emergency department (ED) visits, office-based visits, hospital-based outpatient visits, inpatient visits, and prescription drugs.

RESULTS

Immigrants accounted for $39.5 billion (SE=$4 billion) in health care expenditures. After multivariate adjustment, per capita total health care expenditures of immigrants were 55% lower than those of US-born persons ($1139 vs $2546). Similarly, expenditures for uninsured and publicly insured immigrants were approximately half those of their US-born counterparts. Immigrant children had 74% lower per capita health care expenditures than US-born children. However, ED expenditures were more than 3 times higher for immigrant children than for US-born children.

CONCLUSIONS

Health care expenditures are substantially lower for immigrants than for US-born persons. Our study refutes the assumption that immigrants represent a disproportionate financial burden on the US health care system.

Health Care for Children and Youth in the United States: 2002 Report on Trends in Access, Utilization, Quality, and Expenditures

OBJECTIVE

To examine changes in insurance coverage, health care utilization, perceived quality of care, and expenditures for children and youth in the United States using data from 1987-2001.

METHODS

Three national health care databases serve as the sources of data for this report. The Medical Expenditure Panel Survey (1996-2001) provides data on insurance coverage, utilization, expenditures, and perceived quality of care. The National Medical Expenditure Survey (1987) provides additional data on utilization and expenditures. The Nationwide Inpatient Sample (1995-2000) from the Healthcare Cost and Utilization Project provides information on hospitalizations.

RESULTS

The percent of children uninsured for an entire year declined from 10.4% in 1996 to 7.7% in 1999. Most changes in children's health care occurred between 1987 and the late 1990s. Overall utilization of hospital-based services has declined significantly since 1987, especially for inpatient hospitalization. Several of the observed changes from 1987 varied significantly by type of health insurance coverage, poverty status, and geographic region. Quality of care data indicate some improvement between 2000 and 2001, which varies by insurance coverage. Overall, mean length of stay of hospitalizations did not change significantly from 1995 to 2000, but changes in the prevalence of hospitalizations and the length of stay associated with age-specific diagnoses were evident during this time period.

CONCLUSIONS

Health care for children and youth has changed significantly since 1987, with most of the changes occurring between 1987 and 1996. Insurance coverage has improved, the site of care has shifted toward ambulatory sites, hospital utilization has declined, and expenditures on children as a proportion of total expenditures have decreased. Variation in these changes is evident by insurance status, poverty, and region.
