Bridging the gap between robotic technology and health care

Although technology and computation power have become more and more present in our daily lives, we have yet to see the same tendency in robotics applied to health care. In this work we focused on the study of four distinct applications of robotic technology to health care, named Robotic Assisted Surgery, Robotics in Rehabilitation, Prosthetics and Companion Robotic Systems. We identified the main roadblocks that are limiting the progress of such applications by an extensive examination of recent reports. Based on the limitations of the practical use of current robotic technology for health care we proposed a general modularization approach for the conception and implementation of specific robotic devices. The main conclusions of this review are: (i) there is a clear need of the adaptation of robotic technology (closed loop) to the user, so that robotics can be widely accepted and used in the context of heath care; (ii) for all studied robotic technologies cost is still prohibitive and limits their wide use. The reduction of costs influences technology acceptability; thus innovation by using cheaper computer systems and sensors is relevant and should be taken into account in the implementation of robotic systems.

The development of health technology assessment in Brazil.

OBJECTIVES The aim of this study was to describe the developing health technology assessment (HTA) activities in Brazil, both historically and in the present day. METHODS This report is a descriptive analysis based on personal experiences of the authors and on selected literature. RESULTS Interest in HTA in Brazil began in the mid-1980s. Several seminars and consultations were held, often with invited foreign participants. A cadre of people with knowledge and expertise in HTA was gradually developed. In 2003, several policies were developed by the federal government of Brazil to encourage HTA and base clinical, management, and policy decisions on HTA. During the past 5 years, institutional development has been rapid in government, private companies (mainly prepaid health plans), academia, and research institutes. Further policy changes are needed to maximize the impact of these developments. Nevertheless, although the growing network of HTA programs will have a considerable impact on Brazilian health care, further institutional development could stimulate this change. CONCLUSIONS It would be desirable if the Federal Ministry of Health of Brazil were to proceed to develop a national agency for HTA.

Papel do responsável pelos cuidados à saúde do paciente no domicílio: um estudo de caso

This work aims to identify the caregiver difficults in assisting pacients at home in order to establish recommendations to improve pacient care. A special form was developed to collect data on 103 pacients and 181 caregivers during the period of Sept. 1999 and Jan. 2000. The findings pointed out that pacients with low quality of care have a long time of dependency on care (p<0,0001). The authors believe that the quality of care to these patients can be improved if they get special attention, such as assistive technologies, and caregivers access adequate information.This work aims to identify the caregiver difficults in assisting pacients at home in order to establish recommendations to improve pacient care.

The relation between anti-hepatitis A virus antibodies and residence water access in Rio de Janeiro, Brazil.

OBJECTIVES The objective of this study was to analyse the relation between residence water access (water taps) and hepatitis A virus (HAV) antibodies, associated with socio-economic, environmental and demographic factors. METHODS A logistic regression model was used for estimating the relation between residential water access (presence of water taps inside the house) and HAV antibodies, related to confounding effects of selected variables. The odds ratios estimated by the model were used as incidence density ratios (IDR) for the analysis of the water access-antibody association. Data were obtained from a cross-sectional study on the seroprevalence of hepatitis A in 3779 volunteers from Duque de Caxias city, greater Rio de Janeiro, Brazil. Participants were selected according to an age-specified random sampling survey. RESULTS Besides water access (main variable of interest), age, monthly family income, housewife schooling, persons per room, proximity to open sewage channels and consumption water treatment were statistically associated to hepatitis A seroprevalences. An interaction between water access and proximity to open sewage channels was detected. Persons living in residences distant from an open sewage channel had a water access-antibody IDR of 2.5 (95% CI [1.4; 4.3]), in contrast to 1.1 for those living close to such channels. CONCLUSIONS Although indirectly measured through the proxy variable water access, personal hygiene, in conjunction with the absence of open sewage channels in the proximity of the residence, was an important factor for low HAV seroprevalence study population.

A record linkage process of a cervical cancer screening database

This paper aims at to present the integration of the files of the Brazilian Cervical Cancer Information System (SISCOLO) in order to identify all women in the system. SISCOLO has the exam as the unit of observation and the women are not uniquely identified. It has two main tables: histology and cytology, containing the histological and cytological examinations of women, respectively. In this study, data from June 2006 to December 2009 were used. Each table was linked with itself and with the other through record linkage methods. The integration identified 6236 women in the histology table and 1,678,993 in the cytology table. 5324 women from the histology table had records in the cytology table. The sensitivities were above 90% and the specificities and precisions near 100%. This study showed that it is possible to integrate SISCOLO to produce indicators for the evaluation of the cervical cancer screening programme taking the woman as the unit of observation.

Modelo de simulação para estimar a infraestrutura necessária à assistência oncológica no sistema público de saúde

Objective. To develop a simulation model using public data to estimate the cancer care infrastructure required by the public health system in the state of Sao Paulo, Brazil. Method. Public data from the Unified Health System database regarding cancer surgery, chemotherapy, and radiation therapy, from January 2002–January 2004, were used to estimate the number of cancer cases in the state. The percentages recorded for each therapy in the Hospital Cancer Registry of Brazil were combined with the data collected from the database to estimate the need for services. Mixture models were used to identify subgroups of cancer cases with regard to the length of time that chemotherapy and radiation therapy were required. A simulation model was used to estimate the infrastructure required taking these parameters into account. Results. The model indicated the need for surgery in 52.5% of the cases, radiation therapy in 42.7%, and chemotherapy in 48.5%. The mixture models identified two subgroups for radiation therapy and four subgroups for chemotherapy with regard to mean usage time for each. These parameters allowed the following estimated infra-structure needs to be made: 147 operating rooms, 2 653 operating beds, 297 chemo-therapy chairs, and 102 radiation therapy devices. These estimates suggest the need for a 1.2-fold increase in the number of chemotherapy services and a 2.4-fold increase in the number of radiation therapy services when compared with the parameters cur-rently used by the public health system. Conclusion. A simulation model, such as the one used in the present study, permits better distribution of health care resources because it is based on specific, local needs.

Severity of a case for outcome assessment in health care — definitions and classifications of instruments

Severity of a case is one of the ingredients in management systems. Severity adjustment systems have limitations, and confusion and diversity characterize definitions of severity of a case. These facts may be a consequence of lack of conceptual knowledge. Based on a holistic theory of health, we introduce a definition of severity of a case from a patient perspective. Here severity is characterized as having two basic components: disease severity and illness severity; and five dimensions: suffering, disabilities, risk of suffering, risk of disabilities and risk of death. A classification of instruments as measures of severity dimensions is presented. This classification is based on definition and application criteria. The articles main contribution is to combine theoretical and practical knowledge about severity of a case, which may empower implementations of outcome management systems in health care.

EUROSCAN INTERNATIONAL NETWORK MEMBER AGENCIES: THEIR STRUCTURE, PROCESSES, AND OUTPUTS

Objectives: The EuroScan International Network is a global network of publicly funded early awareness and alert (EAA) systems for health technologies. We describe the EuroScan member agency systems and methods, and highlight the potential for increased collaboration. Methods: EuroScan members completed postal questionnaires supplemented with telephone interviews in 2012 to elicit additional information and check equivalence of responses. Information was updated between March and May 2013. Results: Fifteen of the seventeen member agencies responded. The principal purpose of agencies is to inform decisions on coverage or reimbursement of health services and decisions on undertaking secondary research. The main users of information are national governments; health professionals; health services purchasers, commissioners, and decision makers; and healthcare providers. Most EuroScan agencies are small with almost half having fewer than two whole time equivalent staff. Ten agencies use both active and passive identification approaches, four use only active approaches. Most start identification in the experimental or investigational stages of the technology life cycle. All agencies assessed technologies when they are between the investigational and established, but under diffusion stages. Barriers to collaboration revolve around different system aims, purposes, and requirements; a lack of staff, finance, or opportunity; language differences; and restrictions on dissemination. Conclusions: Although many barriers to collaboration were identified, the majority of agencies were supportive of increased collaboration either involving the whole EuroScan Network or between individual agencies. Despite differences in the detailed identification processes, members thought that this was the most feasible phase to develop additional collaboration.

Uso da tecnologia como ferramenta de avaliação no cuidado clínico de recém-nascidos prematuros

OBJECTIVE: To assess the use of the Neonatal Therapeutic Intervention Scoring System (NTISS) as a tool to quantify the use of technology in neonatal intensive care units, in order to detect discrepancies in the care provided to high-risk newborn infants. METHODS: Prospective, descriptive, observational study about the use of technology in two neonatal intensive care units (one public and one private). The NTISS was calculated on a daily basis up to the discharge or death of preterm newborns with gestational age equal to or less than 32 weeks. We gathered data about prenatal clinical conditions, birth characteristics, and conditions on admission to the intensive care unit, as well as about the morbidities developed during the hospital stay. The risks of preterm newborns were adjusted by means of the Score for Neonatal Acute Physiology, Perinatal Extension, Version II (SNAPPE-II). Students t test, chi-square test, Fishers exact test, and the Mann-Whitney/Wilcoxons test were used for the descriptive analysis. The study was approved by the local Research and Ethics Committee. RESULTS: We assessed 44 newborn infants from the public intensive care unit and 52 from the private one. On admission, the severity score (SNAPPE-II) and the overall NTISS were statistically similar in both care units. The curve for the use of technology showed a gradual and progressive decreasing pattern in both care units up to the 31st day. Thereafter, there was a continuous downward trend in the private care unit, but a significant increase in the overall NTISS in the public care unit. The patients from the public care unit developed more morbidities than those from the private unit. CONCLUSION: Patients with similar clinical pictures can be treated with different levels of technological resources. This may have a direct impact on morbidities and on healthcare costs. The NTISS allowed monitoring healthcare and proved efficient in detecting discrepancies in practices that could influence clinical outcomes and operating costs.
