Determinants of Care Seeking for Persons with Low Back and Neck Pain Treated By Physicians, Chiropractors or Physical Therapists

Chevan, Julia 01 January 2006 (has links)
Low back and neck pain are frequent reasons for adults to seek healthcare. Three types of practitioners are commonly used in the United States: physicians, chiropractors and physical therapists. In this study, Andersen's "Behavioral Model of Health Services Utilization" is used to examine care seeking and provider selection. Estimates of back and neck pain prevalence in the United States are presented as well as care seeking rates and care consumption estimates for patients who used the three providers of interest. Multivariate regression analyses are presented that model the variables that most influence care seeking and provider selection.Cases with the conditions of low back pain and neck pain were drawn from the Medical Expenditure Panel Survey Panel 6 participants. Episodes of care and non-care were defined and the provider used during an episode was identified.Determinants of care seeking for low back pain included MSA status, insurance coverage, perceived health status, number of comorbidities and number of episodes. Determinants of care seeking for neck pain included insurance coverage and number of episodes. When condition was included in the analysis, it was a determinant of care seeking. All of these variables are enabling factors or need factors in Andersen's model.In the analysis of provider selection for low back pain, variables that determined the provider from whom care was sought included patient age, gender, race, ethnicity, marital status, MSA status, insurance coverage, perceived health status, if the condition was disabling and number of episodes. In the analysis of provider selection for neck pain, variables that determined the provider from whom care was sought included patient ethnicity, marital status, and if the condition was disabling.Andersen's Behavioral Model adequately predicts care seeking in LBP and NP with enabling and need factors playing a predominant role. In terms of equity of access this finding indicates a problem of access to care for persons who were uninsured. In the case of provider selection, all the constructs from the model were found to have a role in prediction indicating that access may be inequitable in the case of some providers.

Integrating Health Care Systems to Maintain Quality Care and to Manage Cost

Noble, Marilynn 01 January 2019 (has links)
The rising cost of health care in the Philippines is a concern for the Department of Defense and TRICARE beneficiaries. The purpose of this quantitative cross-sectional research study was to determine the efficacy and acceptability of a different method to deliver health care to increase access to health care and decrease out-of-pocket costs while maintaining quality of care for TOP Standard beneficiaries who receive health care under the Philippine Demonstration. Secondary data was used to determine the acceptability of an alternative reimbursement methodology to decrease cost but maintain access to quality care. The Andersen's behavioral health care model and the Donabedian quality health care model were used to interpret the study results. A data set of 180 participants was evaluated using a cross-sectional quantitative methodology. Two Spearman correlations were used to examine the relationship between financial burden and satisfaction (r = .41, p < .001) and financial burden and confidence (r = .44, p < .001). Linear and binary regressions assessed the effects of age and gender on satisfaction with health care finder functionality when requesting a waiver (F (2,26) = 1.22, p = .313, R2 = .09). A computation of one-sample t-tests to determine the impact of a closed network, beneficiary out-of-pocket cost, and quality health care in Demonstration areas found the beneficiaries were satisfied with the demonstration. An analysis of the claims data pre and post demonstration showed a difference in the patients' out-of-pocket expenses and the acceptability and preference for a closed network. Social change was demonstrated by a decrease in the cost for TRICARE standard beneficiaries in the Philippines.

“it’s here, but you can’t always get to it”: the experience of women in prison with gynecological care

Sabbagh Steinberg, Nadia G 01 December 2018 (has links)
Since the war on drugs in the 1980s, the United States has seen an exponential rise in the number of imprisoned individuals. This increase has been particularly dramatic for women. Nationwide, the population of women in prison has grown by 834% over the past 40 years, more than double the growth rate of men. Compared with incarcerated men, women in prison have higher rates of substance abuse, histories of physical and sexual abuse, mental illness, infectious disease and chronic illness. Most women in prison are defined by a challenging intersection of lower socioeconomic status and largely racial, ethnic, and minority gender status. This combination of identity factors both contributes to their health disparities and influences their experiences with health care. Given that the majority of women in prison are of reproductive age, gynecological care is a central aspect of women’s overall health care. However, women in prison are a small minority of the overall incarcerated population, and because of this, their gender-specific health needs are frequently unacknowledged. Using a feminist epistemology, this qualitative multiple case study provides an examination of the experiences of women before prison and in prison with gynecological care and prison staff’s experiences providing this care. The Gelberg Andersen Behavioral Model for Vulnerable Populations is adapted here for the study of women in prison. The model explains factors enabling and impeding women’s utilization of health care services, including previous health care experiences, prison infrastructure, and personal autonomy. Women in contact with the criminal justice system face difficulties accessing health care both outside and inside prison. Barriers on the outside included lack of health insurance, being addicted to drugs, and prioritizing children’s needs first. On the inside women cited a lack of confidentiality, the absence of trust in providers, and the inability to participate in treatment decision-making. In the case of women in prison, multiple external oppressions result in internalized negative beliefs. Such feelings of powerlessness, lack of control, curtailed agency, and threatened self-worth ultimately influence how women experience gynecological care in prison. Policy, practice and research implications are provided to meet the gender specific health needs of women in prison.

On the distribution of the time to ruin and related topics

Shi, Tianxiang 19 June 2013 (has links)
Following the introduction of the discounted penalty function by Gerber and Shiu (1998), significant progress has been made on the analysis of various ruin-related quantities in risk theory. As we know, the discounted penalty function not only provides a systematic platform to jointly analyze various quantities of interest, but also offers the convenience to extract key pieces of information from a risk management perspective. For example, by eliminating the penalty function, the Gerber-Shiu function becomes the Laplace-Stieltjes transform of the time to ruin, inversion of which results in a series expansion for the associated density of the time to ruin (see, e.g., Dickson and Willmot (2005)). In this thesis, we propose to analyze the long-standing finite-time ruin problem by incorporating the number of claims until ruin into the Gerber-Shiu analysis. As will be seen in Chapter 2, many nice analytic properties of the original Gerber-Shiu function are preserved by this generalized analytic tool. For instance, the Gerber-Shiu function still satisfies a defective renewal equation and can be generally expressed in terms of some roots of Lundberg's generalized equation in the Sparre Andersen risk model. In this thesis, we propose not only to unify previous methodologies on the study of the density of the time to ruin through the use of Lagrange's expansion theorem, but also to provide insight into the nature of the series expansion by identifying the probabilistic contribution of each term in the expansion through analysis involving the distribution of the number of claims until ruin. In Chapter 3, we study the joint generalized density of the time to ruin and the number of claims until ruin in the classical compound Poisson risk model. We also utilize an alternative approach to obtain the density of the time to ruin based on the Lagrange inversion technique introduced by Dickson and Willmot (2005). In Chapter 4, relying on the Lagrange expansion theorem for analytic inversion, the joint density of the time to ruin, the surplus immediately before ruin and the number of claims until ruin is examined in the Sparre Andersen risk model with exponential claim sizes and arbitrary interclaim times. To our knowledge, existing results on the finite-time ruin problem in the Sparre Andersen risk model typically involve an exponential assumption on either the interclaim times or the claim sizes (see, e.g., Borovkov and Dickson (2008)). Among the few exceptions, we mention Dickson and Li (2010, 2012) who analyzed the density of the time to ruin for Erlang-n interclaim times. In Chapter 5, we propose a significant breakthrough by utilizing the multivariate version of Lagrange's expansion theorem to obtain a series expansion for the density of the time to ruin under a more general distribution assumption, namely when interclaim times are distributed as a combination of n exponentials. It is worth emphasizing that this technique can also be applied to other areas of applied probability. For instance, the proposed methodology can be used to obtain the distribution of some first passage times for particular stochastic processes. As an illustration, the duration of a busy period in a queueing risk model will be examined. Interestingly, the proposed technique can also be used to analyze some first passage times for the compound Poisson processes with diffusion. In Chapter 6, we propose an extension to Kendall's identity (see, e.g., Kendall (1957)) by further examining the distribution of the number of jumps before the first passage time. We show that the main result is particularly relevant to enhance our understanding of some problems of interest, such as the finite-time ruin probability of a dual compound Poisson risk model with diffusion and pricing barrier options issued on an insurer's stock price. Another closely related quantity of interest is the so-called occupation times of the surplus process below zero (also referred to as the duration of negative surplus, see, e.g., Egidio dos Reis (1993)) or in a certain interval (see, e.g., Kolkovska et al. (2005)). Occupation times have been widely used as a contingent characteristic to develop advanced derivatives in financial mathematics. In risk theory, it can be used as an important risk management tool to examine the overall health of an insurer's business. The main subject matter of Chapter 7 is to extend the analysis of occupation times to a class of renewal risk processes. We provide explicit expressions for the duration of negative surplus and the double-barrier occupation time in terms of their Laplace-Stieltjes transform. In the process, we revisit occupation times in the content of the classical compound Poisson risk model and examine some results proposed by Kolkovska et al. (2005). Finally, some concluding remarks and discussion of future research are made in Chapter 8.
