Abstract Purpose This study aimed to examine population-based trends in the incidence rate, health care consumption, and work absence with associated costs in patients with rib fractures. Methods A retrospective nationwide epidemiologic study was performed with data from patients with one or more rib fractures presented or admitted to a hospital in the Netherlands between January 1, 2015 and December 31, 2018 and have been registered in the Dutch Injury Surveillance System (DISS) or the Hospital Discharge Registry (HDR). Incidence rates were calculated using data from Statistics Netherlands. The associated direct health care costs, costs for lost productivity, and years lived with disability (YLD) were calculated using data from a questionnaire. Results In the 4-year study period, a total of 32,124 patients were registered of which 19,885 (61.9%) required hospitalization with a mean duration of 7.7 days. The incidence rate for the total cohort was 47.1 per 100,000 person years and increased with age. The mean associated direct health care costs were €6785 per patient and showed a sharp increase after the age of 75 years. The mean duration of work absence was 44.2 days with associated mean indirect costs for lost productivity of €22,886 per patient. The mean YLD was 0.35 years and decreased with age. Conclusion Rib fractures are common and associated with lengthy HLOS and work absenteeism as well as high direct and indirect costs which appear to be similar between patients with one or multiple rib fractures and mostly affected by admitted patients and age.

Abstract Background Primary health care services are the cornerstone of all health systems. Having clear data on allocated human resources is essential for planning. This work intended to map and compare the primary health care human resources of the five administrative regions (ARS) of the Portuguese public health system, so that better human resources management can be implemented. Methods The chosen design was a descriptive cross sectional study. Each of the five ARS were divided into primary health care clusters, which included several primary health care units. All of these units periodically sign a “commitment letter”, where they stand their service commitments to the covered population. This includes allocated health professionals (doctors, nurses), and the information is publicly accessible at www.bicsp.min-saude.pt. Data was collected for 2017, the year for which more commitment letters were available. Several ratios were calculated: patients/health professional; patients/doctor (family medicine specialists and residents); patients/nurse and patients/family medicine specialist. Mean, standard deviation, minimum and maximum values were calculated. Results National patients/health professional ratio was 702 with the mean of the 5 ARS calculated at 674+-7.15% (min 619, max 734) whilst the national patients/doctor ratio was 1247 with the mean of the 5 ARS calculated at 1217+-7.17% (min 1074, max 1290). National patients/nurse ratio was 1607 with the mean of the 5 ARS calculated at 1529+-13.08% (min 1199, max 1701). Finally, national patients/family medicine specialist ratio was 1711 with the mean of the 5 ARS calculated at 1650+-6,36% (min 1551, max 1795). Conclusions Human resources were differently spread across Portugal, with variations between the five ARS in all ratios. The largest differences occur between nursing staff, and may translate into inequities of access, with impact on health results. A more homogeneous human resources allocation should be implemented. Key messages Human resources in the Portuguese primary health care services are not homogeneously allocated. A better and more homogeneous allocation of human resources should be implemented to reduce access health inequities.

AbstractPurpose:Training emergency department (ED) personnel in the care of victims of mass-casualty incidents (MCIs) is a highly challenging task requiring unique and innovative approaches. The purpose of this study was to retrospectively explore the value of high-fidelity simulators in an exercise that incorporates time and resource limitation as an optimal method of training health care personnel in mass-casualty care.Methods:Mass-casualty injury patterns from an explosive blast event were simulated for 12 victims using high-fidelity computerized simulators (HFCS). Programmed outcomes, based on the nature of injuries and conduct of participants, ranged from successful resuscitation and survival to death. The training exercise was conducted five times with different teams of health care personnel (n = 42). The exercise involved limited time and resources such as blood, ventilators, and imaging capability. Medical team performance was observed and recorded. Following the exercise, participants completed a survey regarding their training satisfaction, quality of the exercise, and their prior experiences with MCI simulations. The Likert scale responses from the survey were evaluated using mean with 95% confidence interval, as well as median and inter-quartile range. For the categorical responses, the frequency, proportions, and associated 95% confidence interval were calculated.Results:The mean rating on the quality of experiences related trainee survey questions (n = 42) was between 4.1 and 4.6 on a scale of 5.0. The mean ratings on a scale of 10.0 for quality, usefulness, and pertinence of the program were 9.2, 9.5, and 9.5, respectfully. One hundred percent of respondents believed that this type of exercise should be required for MCI training and would recommend this exercise to colleagues. The five medical team (n = 5) performances resulted in the number of deaths ranging from two (including the expectant victims) to six. Eighty percent of medical teams attempted to resuscitate the “expectant” infant and exhausted the O- blood supply. Sixty percent of medical teams depleted the supply of ventilators. Forty percent of medical teams treated “delayed” victims too early.Conclusion:A training exercise using HFCS for mass casualties and employing limited time and resources is described. This exercise is a preferred method of training among participating health care personnel.

Conducting Research

Research in primary health care (PHC) is underdeveloped and scarce, especially in developing countries. It is important to understand the attitudes and aspirations of PHC physicians for the promotion of research. The aim of this study was to determine the attitudes of PHC physician managers toward research in Qassim province and to identify barriers that impede performing research in the PHC system. The study was based on social cognitive theory framework, and was pre-experimental with a ‘one-group pre-test–post-test’ design. The study participants were physician managers in PHC administration, Qassim. The participants’ attitudes were measured by adapting statements from the Attitude Towards Research scale. The intervention was the 1-day training program ‘Introduction to Research in Primary Health Care’. A total of 23 PHC physicians participated in the study. The mean age of the participants was 45.4 (±1.6) years, and the mean years of work experience was 16.2 (±2.2) years. Only one participant had an article published in a peer-reviewed journal. The results of the study showed that PHC physicians had a baseline positive attitude toward research that was further enhanced after participating in an introductory research-training program. During the pre-test, out of the total score of 63, the mean score on attitude toward research was 48.35 (±6.8) while the mean total attitude score in the post-test was 49.7 (±6.6). However, the difference was not statistically significant at P < 0.05. The item with the highest score regarded the role of research in the improvement of health care services, while the lowest-scoring item was about support from administration to conduct research. The participants recognised lack of skills, lack of training and inadequate resources as major barriers in conducting research. Our study results suggest that the PHC physicians’ positive attitudes toward research can be further improved through in-service training. To promote research in PHC in Qassim, regular research-training programs and incentives for conducting research should be provided to the PHC physicians.
