Urgent Care Centers (UCCs) are a recent innovation in the American system of health care delivery. The number of UCCs has increased significantly in recent years. Many researchers point out that the rapid growth of UCCs is expected to escalate during the next few decades. This growth will create more competition among providers of these facilities in the health care market, and the competition could lead to an uneven distribution of UCCs within cities. While health officials and planners are interested in attracting more patients by expanding UCC services, they are often unfamiliar with the factors that go into site selection decisions. Understanding the factors influencing UCC location is crucial to explaining why UCCs cluster in certain urban areas, while other areas are under-served. It is also important for providers who want to enhance accessibility of special population segments to UCC locations. This study uses the Portland metropolitan area as a case study. Due to the lack of access to providers' propriety data, the specific problem targeted here uses publicly available data as a proxy for providers' data to determine the factors influencing UCC location. The essence of this research is to show how these factors explain and predict existing locations of UCCs and to find out how well this publicly available data explains UCC providers' locational behavior. Most of the data for this study is provided by Metro of Portland. Other data are collected utilizing surveys and data from different public agencies and published reports. Logit analysis is used to find out which factors explain existing UCC location. The empirical findings of this research substantiate the existence of a strong relationship between the location of UCCs and land use factors. This study highlights the complexity and importance of understanding the factors influencing the location of UCCs. It rejects prior arguments that UCC location is influenced by some demographic and socioeconomic factors, while it introduces land use factors as the major determinants of UCC location. However, this study concluded that land use factors influence considered a rare phenomena that should be carried out for future research and that demographic factors may still have an indirect effect on UCC location.

O absenteísmo, ou seja, a falha no atendimento (FA) ou não atendimento (NA) dos usuários nos serviços de saúde do Sistema Único de Saúde (SUS) é um assunto de crescente interesse devido ao grande número de pessoas aguardando atendimento e ao contexto econômico atual. A problemática acarreta prejuízos a todos envolvidos, pois prolonga a conclusão diagnóstica, prejudica o tratamento, diminui a produtividade do prestador, causa aumento de tempo na espera por atendimento dos demais usuários e desperdício de recursos públicos. Portanto, o objetivo deste estudo foi compreender os motivos do absenteísmo nos serviços de saúde e as estratégias praticadas para a redução de falhas no atendimento. Trata-se de pesquisa qualitativa, com desenho de estudo de caso descritivo-exploratório, baseado em entrevistas semi-estruturadas e grupo focal. A coleta de dados visou a identificar diferentes opiniões e explicações para o absenteísmo, as estratégias e perspectivas utilizadas pelas equipes de saúde da AME e das secretarias de saúde de quatro municípios. Foram selecionados quatro casos traçadores para evidenciar experiências típicas, ou seja, dois municípios que pudessem demonstrar uma dinâmica mais exitosa no controle do absenteísmo e outros dois representantes de experiências menos exitosas. A análise permitiu representar o perfil dos serviços locais \"em situação\", discutindo estratégias, processos de trabalho, facilidades e dificuldades. Foi possível evidenciar as diferentes características e fluxos nos quatro municípios estudados, bem como a pequena ou inexistente discussão sobre o absenteísmo. Durante as entrevistas, nenhum dos entrevistados sabia ao certo a taxa de falha de atendimento e demonstraram-se surpresos quando informados de que são em média 560 consultas especializadas perdidas por mês. Todos concordaram que devem ser adotadas estratégias de prevenção ao absenteísmo, e, principalmente, esses dados devem ser divulgados à população. Concordaram ainda que outros setores podem e devem ser copartícipes na efetivação de uma rede local de atenção à saúde, no registro do fluxo dos usuários, utilizando diferentes espaços para a promoção da frequência ao atendimento e educação em saúde. Foram compartilhadas várias estratégias e propostas de mudança para reorganização municipal e alteração nos fluxos de trabalho, bem como comunicação entre os serviços e os usuários. Este estudo proporcionou a oportunidade de discussão entre os envolvidos no processo de acesso aos serviços de saúde do AME Araçatuba. Permitiu a reflexão sobre responsabilidades e papéis dos atores no processo. O folder produzido a partir desta pesquisa e apoiado pela revisão bibliográfica será utilizado na capacitação de profissionais, com a finalidade de subsidiar o planejamento em saúde e melhorar a assistência proposta ao usuário do SUS. / Absenteeism, that is, the non-attendance of users in health services of Unified Health System is a subject of growing interest due to large number of people waiting for care and current economic context. The problem entails damages to all involved, since it prolongs the diagnostic conclusion, impairs the treatment, decreases the provider\'s productivity, causes an increase in waiting time for other users\' attention, and wastage of public resources. Therefore, the aim in this study was to understand the reasons for absenteeism in health services and the strategies used to reduce service failures. It is qualitative research, in the design of the case study, descriptive-exploratory based on interstructure interviews and focal group. The interview is a technique of collecting data through group interactions, mediated by a facilitator, to encourage the formation of opinions on the absenteeism, strategies and perspectives of the health teams. Four tracer cases were selected to show typical experiences, that is, two municipalities that could demonstrate the most successful dynamics in control of absenteeism and two other less successful representatives of the same. The analysis allowed to represent the profile of local services \"in situation\", discussing strategies, work processes, facilities, and difficulties. It was possible to show the different characteristics and flows between the four municipalities studied and how little or no discussion about absenteeism is available. During the interview, none of municipalities interviewed knew for certain that the rate of service failure was surprising when informed that they are on average 560 specialized consultations lost per month. All agreed that strategies should be taken, and especially, these data should be made public. They also agree that other sectors can and should be partners in the implementation of the local health care network, in execution of flow users, use of other spaces for awareness, and education in health. Several strategies and proposals for change have been shared for municipal reorganization and changes in workflows and communication between services and users. This study provided the opportunity for discussion among those involved in the process of access to the health services of Ambulatory Care of Araçatuba. It allowed for reflection on the responsibilities and roles of actors in the process. The folder produced from this research and supported by bibliographic review will be used to train professionals, with the purpose of subsidizing health planning and improving the proposed assistance to Unified Health System users.

This project was done with the vision that it would simplify and improve outpatient treatment of substance abusers through a rehabilitation software program with 24-7 access availability. By developing an easy-to-use interface for out-patient substance abuse patients, they along with their counselors, administrators and insurance agencies, will be able to facilitate continuous communication during the course of a patient's treatment.
