![Page 7: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/7.jpg)
Definitions of Access & Quality
• Access to care– Timely use of personal health services to achieve the
best possible health outcomes (IOM)
• Quality health care: – Safe, effective, patient-centered, timely, efficient, and
equitable (IOM)– Accessible, family-centered, continuous, comprehensive,
coordinated, compassionate & culturally effective (AAP)
![Page 8: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/8.jpg)
Importance of Access
• Importance of Access– Ensuring the receipt of preventive services– A prerequisite for optimal management of chronic
childhood diseases– Influences children’s physical & emotional growth,
development, overall health and well being
![Page 9: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/9.jpg)
Associated Factors - Access
• Insurance (continuity, type of insurance)• Having a personal health care provider• Having a usual source of care• Race/ethnicity
![Page 10: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/10.jpg)
Associated Factors - Quality
• Race/ethnicity • Insurance• Primary household language• Income• Parental Education
![Page 11: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/11.jpg)
Prevalence in Georgia
• Access to care– Identified as a major health concern for all MCH
populations especially children in Georgia– Based on 2007 NSCH (Georgia children ages 0-17)
• 88.3% had a preventive medical visit in the past year• 58.5% received care within a medical home• Family-centered component of medical home
– HCP spends enough time (79.3%); HCP listens carefully (89.8%)– HCP provides specific needed information (87.8%)– HCP helps parent feel like a partner in care (89.0%)
![Page 12: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/12.jpg)
Gaps & Study Question
• No in-depth exploration of factors associated with access and quality of health care in Georgia
• Study Question: – What are the determinants of access to quality health
care in Georgia among children ages 4-17 years?
![Page 13: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/13.jpg)
Methods
• Study Design• Dependent Variable• Independent Variables – Andersen’s Framework• Data Analysis
![Page 14: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/14.jpg)
Study Design
• Merged dataset:– 2007 NSCH PUF (Interview completion rate: 66%)– Selected 2007 variables from the 2008 Area Resource
File– Medically Underserved Area (MUA) variable for Georgia
• Study Population– Georgia children 4-17 years of age (N = 1,397)
![Page 15: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/15.jpg)
Dependent Variable
• Access to quality health care– Access to care
• Utilization of preventive medical visit in the past year• No occasion of delay or denial of needed care in the past year
– Quality of health care• Health care provider spends enough time with child• Listens carefully to parent• Is sensitive to family values and customs• Provides specific needed information• Makes parent feel like a partner in child’s care
![Page 16: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/16.jpg)
Dependent Variable
• Access to care: Yes/No• Quality of Health Care: Higher/Moderate/Lower• Access to quality health care
– Access to higher quality care– Access to moderate quality care– Access to lower quality care– No access to care
![Page 17: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/17.jpg)
Independent Variables:Andersen’s Theoretical Framework
![Page 18: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/18.jpg)
Data Analysis
• Descriptive Statistics• Bivariable analysis (Chi-square tests)• Significant testing – alpha=0.05• Multivariable Analysis
– Multinomial logistic regression (genlogit approach)– First 2 levels of outcome were collapsed– Access to higher/moderate versus lower quality care– Access to lower quality care versus no access to care
![Page 19: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/19.jpg)
Data Analysis
• Multivariable Analysis– Domain-specific models– Full models (all domains simultaneously)– Ρ-value=0.3 for entry into models and retainership in
final models– Additional analysis on subpopulation of CSHCN (N=319)
• All analysis – SAS-callable SUDAAN 10.0.1

Discussion
• Summary of Findings• Public Health Implications• Strengths• Limitations
![Page 27: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/27.jpg)
Summary of Findings
• About a third of Georgia children ages 4-17 years had access to higher quality care
• Higher odds of having access to higher/moderate quality care (vs. lower quality care)– Environmental: No presence of vandalism– Predisposing: Being female, living in a strongly supportive
neighborhood– Enabling: Having a usual source of care– Need: CSHCN status, excellent/very good health status
![Page 28: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/28.jpg)
Summary of Findings
• Lower odds of having access to higher/moderate quality care (vs. lower quality care)– Predisposing: Black, NH and Hispanic children– Enabling:
• Children in all other categories of insurance (except ref. group)
• Children living in >100-200%, >200-300%, and above 400% of the FPL
![Page 29: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/29.jpg)
Summary of Findings• Higher odds of having access to lower quality care
– Predisposing: Black, NH & Hispanic children– Enabling:
• Children with continuous-adequate-public insurance• Children living in >200-300% and 400% of the FPL
• CSHCN population– Predisposing: Children ages 4-9yrs (higher odds of having
access to higher/moderate quality care)– Enabling: Children with a usual source of care (higher odds
of having access to lower quality care)
![Page 30: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/30.jpg)
Public Health Implications
• Insurance Coverage– Most mutable factor– Needs to be continuous and adequate– Public programs (Medicaid & Peach Care for Kids)
• Minority race/ethnicity– Cultural differences between providers and patients
![Page 31: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/31.jpg)
Public Health Implications
• CSHCN population– Outreach to older children (10-17) for regular check ups
• May help with transition plans– Training to help pediatricians feel more competent
![Page 32: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/32.jpg)
Strengths
• Composite variable of access and quality• Contextual perspective – ARF & MUA variable• State-level estimates to inform program operations• Well established theoretical framework
![Page 33: The Determinants of Timely Access to Quality Health Care](https://reader033.fdocuments.in/reader033/viewer/2022061121/546951e4af7959b6258b6fe2/html5/thumbnails/33.jpg)
Limitations
• Cross-sectional survey• Parent’s perceptions – not verified• Occurrences in the past year• Small numbers – cells had to be collapsed• Lack of multilevel modeling - - future studies
