Association between community health center and rural health clinic presence and county-level hospitalization rates for ambulatory care sensitive conditions: an analysis across eight US states.

ABSTRACT:

Background

Federally qualified community health centers (CHCs) and rural health clinics (RHCs) are intended to provide access to care for vulnerable populations. While some research has explored the effects of CHCs on population health, little information exists regarding RHC effects. We sought to clarify the contribution that CHCs and RHCs may make to the accessibility of primary health care, as measured by county-level rates of hospitalization for ambulatory care sensitive (ACS) conditions.

Methods

We conducted an ecologic analysis of the relationship between facility presence and county-level hospitalization rates, using 2002 discharge data from eight states within the US (579 counties). Counties were categorized by facility availability: CHC(s) only, RHC(s) only, both (CHC and RHC), and neither. US Agency for Healthcare Research and Quality definitions were used to identify ACS diagnoses. Discharge rates were based on the individual's county of residence and were obtained by dividing ACS hospitalizations by the relevant county population. We calculated ACS rates separately for children, working age adults, and older individuals, and for uninsured children and working age adults. To ensure stable rates, we excluded counties having fewer than 1,000 residents in the child or working age adult categories, or 500 residents among those 65 and older. Multivariate Poisson analysis was used to calculate adjusted rate ratios.

Results

Among working age adults, rate ratio (RR) comparing ACS hospitalization rates for CHC-only counties to those of counties with neither facility was 0.86 (95% Confidence Interval, CI, 0.78-0.95). Among older adults, the rate ratio for CHC-only counties compared to counties with neither facility was 0.84 (CI 0.81-0.87); for counties with both CHC and RHC present, the RR was 0.88 (CI 0.84-0.92). No CHC/RHC effects were found for children. No effects were found on estimated hospitalization rates among uninsured populations.

Conclusion

Our results suggest that CHCs and RHCs may play a useful role in providing access to primary health care. Their presence in a county may help to limit the county's rate of hospitalization for ACS diagnoses, particularly among older people.

Project description:Background and objectivesAssisted peritoneal dialysis is a treatment option for individuals with barriers to self-care who wish to receive home dialysis, but previous research suggests that this treatment modality is associated with a higher rate of hospitalization. The objective of our study was to determine whether assisted peritoneal dialysis has a different rate of hospital days compared to in-center hemodialysis.Design, setting, participants, & measurementsWe conducted a multicenter, retrospective cohort study by linking a quality assurance dataset to administrative health data in Ontario, Canada. Subjects were accrued between January 1, 2004 and July 9, 2013. Individuals were grouped into assisted peritoneal dialysis (family or home care assisted) or in-center hemodialysis on the basis of their first outpatient dialysis modality. Inverse probability of treatment weighting using a propensity score was used to create a sample in which the baseline covariates were well balanced.ResultsThe study included 872 patients in the in-center hemodialysis group and 203 patients in the assisted peritoneal dialysis group. Using an intention to treat approach, patients on assisted peritoneal dialysis had a similar hospitalization rate of 11.1 d/yr (95% confidence interval, 9.4 to 13.0) compared with 12.9 d/yr (95% confidence interval, 10.3 to 16.1) in the hemodialysis group (P=0.19). Patients on assisted peritoneal dialysis were more likely to be hospitalized for dialysis-related reasons (admitted for 2.4 d/yr [95% confidence interval, 1.8 to 3.2] compared with 1.6 d/yr [95% confidence interval, 1.1 to 2.3] in the hemodialysis group; P=0.04). This difference was partly explained by more hospital days because of peritonitis. Modality switching was associated with high rates of hospital days per year.ConclusionsAssisted peritoneal dialysis was associated with similar rates of all-cause hospitalization compared with in-center hemodialysis. Patients on assisted peritoneal dialysis who experienced peritonitis and technique failure had high rates of hospitalization.

Project description:BackgroundRegional rates of hospitalization for ambulatory care sensitive conditions (ACSC) are used to compare the availability and quality of ambulatory care but the risk adjustment for population health status is often minimal. The objectives of the study was to examine the impact of more extensive risk adjustment on regional comparisons and to investigate the relationship between various area-level factors and the properly adjusted rates.MethodsOur study is an observational study based on routine data of 2 million anonymous insured in 26 Swiss cantons followed over one or two years. A binomial negative regression was modeled with increasingly detailed information on health status (age and gender only, inpatient diagnoses, outpatient conditions inferred from dispensed drugs and frequency of physician visits). Hospitalizations for ACSC were identified from principal diagnoses detecting 19 conditions, with an updated list of ICD-10 diagnostic codes. Co-morbidities and surgical procedures were used as exclusion criteria to improve the specificity of the detection of potentially avoidable hospitalizations. The impact of the adjustment approaches was measured by changes in the standardized ratios calculated with and without other data besides age and gender.Results25% of cases identified by inpatient main diagnoses were removed by applying exclusion criteria. Cantonal ACSC hospitalizations rates varied from to 1.4 to 8.9 per 1,000 insured, per year. Morbidity inferred from diagnoses and drugs dramatically increased the predictive performance, the greatest effect found for conditions linked to an ACSC. More visits were associated with fewer PAH although very high users were at greater risk and subjects who had not consulted at negligible risk. By maximizing health status adjustment, two thirds of the cantons changed their adjusted ratio by more than 10 percent. Cantonal variations remained substantial but unexplained by supply or demand.ConclusionAdditional adjustment for health status is required when using ACSC to monitor ambulatory care. Drug-inferred morbidities are a promising approach.

Project description:BackgroundResearch on community-level relationships between mental/physical health and child maltreatment is sparse.ObjectiveWe examined how rates of mental distress, physical distress, mental health professionals, and primary care physicians were related to child maltreatment report rates at the county level.Participants and settingU.S. counties from 2014 to 2017.MethodsWithin-between random effects models estimated both within-effects (i.e., longitudinal changes) and between-effects (i.e., inter-county differences) of mental distress rates, physical distress rates, mental health professional rates, and primary care physician rates and their associations with overall and age-specific maltreatment report rates, while adjusting for potential confounders.ResultsLongitudinal increases of mental distress rates marginally significantly (p < .10) increased overall maltreatment report rates (β = 0.50) and significantly (p < .05) increased age 0-5 maltreatment report rates (β = 0.84). Conversely, longitudinal increases of mental health professional rates significantly decreased overall (β = -0.38), age 0-5 (β = -0.59), and age 6-11 (β = -0.31) maltreatment report rates and marginally significantly decreased age 12-17 maltreatment report rates (β = -0.13). Between-effects of metal distress rates and mental health professional rates were mostly not significant. Neither within-effects nor between-effects of physical distress rates and primary care physician rates were significant.ConclusionsOur findings suggest that community mental distress is a risk factor for child maltreatment reports and that community availability of mental health professionals is a protective factor. Community-based strategies to address mental distress and human resource approaches to supply sufficient mental health professionals in communities may help reduce maltreatment report rates in communities. Further research is required to confirm our findings and to better understand underlying mechanisms.

Project description:BackgroundMultisectoral and public-private partnerships are critical in building the necessary infrastructure, policy, and political will to ameliorate health inequity. A focus on health equity by researchers, practitioners, and decision-makers prioritizes action to address the systematic, avoidable, and unjust differences in health status across population groups sustained over time and generations that are beyond the control of individuals. Health equity requires a collective process in shaping the health and wellbeing of the communities in which we live, learn, work, play, and grow. This paper explores multisectoral leaders' understanding of the social, environmental, and economic conditions that produce and sustain health inequity in northern Arizona, a geographically expansive, largely rural, and culturally diverse region.MethodsData are drawn from the Southwest Health Equity Research Collaborative's Regional Health Equity Survey (RHES). The RHES is a community-engaged, cross-sectional online survey comprised of 31 close-ended and 17 open-ended questions. Created to assess cross-sectoral regional and collective capacity to address health inequity and inform multisectoral action for improving community health, the RHES targeted leaders representing five rural northern Arizona counties and 13 sectors. Select open-ended questions were analyzed using an a priori coding scheme and emergent coding with thematic analysis.ResultsAlthough leaders were provided the definition and asked to describe the root causes of inequities, the majority of leaders described social determinants of health (SDoH). When leaders described root causes of health inequity, they articulated systemic factors affecting their communities, describing discrimination and unequal allocation of power and resources. Most leaders described the SDoH by discussing compounding factors of poverty, transportation, housing, and rurality among others, that together exacerbate inequity. Leaders also identified specific strategies to address SDoH and advance health equity in their communities, ranging from providing direct services to activating partnerships across organizations and sectors in advocacy for policy change.ConclusionOur findings indicate that community leaders in the northern Arizona region acknowledge the importance of multisectoral collaborations in improving health equity for the populations that they serve. However, a common understanding of health equity remains to be widely established, which is essential for conducting effective multisectoral work to advance health equity.
