Background: Functional or quality of life questionnaires are important tools in clinical investigations. The Lysholm Knee Scoring Scale and Tegner Activity Scale are knee-specific questionnaires that are widely used to assess knee function.

Purpose: To translate both questionnaires into Thai and to assess the validity and reliability of the Thai versions of the Lysholm and adjusted Tegner scales.

Study Design: Cohort study (diagnosis); Level of evidence, 3.

Methods: The Lysholm and Tegner scales were translated into Thai by using the forward-backward translation protocol. Because cultural modifications were made to the sports used to measure activity on the Tegner scale, the authors of this study refer to the Thai version as the "Thai adjusted Tegner scale." The reliability and validity of the translated scales were evaluated by obtaining the responses of 60 consecutive patients (mean age, 40.5 years; 34 male, 26 female); the patients also completed the Thai version of the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF). Criterion validity was tested by correlating the scores from both translated questionnaires with those from the Thai IKDC-SKF, while reliability was assessed by measuring test-retest reliability and internal consistency.

Results: The Thai Lysholm scale showed a strong correlation with the Thai IKDC-SKF (r = 0.89), while the Thai adjusted Tegner scale showed a moderate correlation with the Thai IKDC-SKF (r = 0.60). The intrarater and test-retest reliability measures were excellent for the Thai Lysholm (intraclass correlation coefficient [ICC], 0.94 and 0.98, respectively) and moderate to good for the Thai adjusted Tegner (ICC, 0.73 and 0.86, respectively). The internal consistency for the Thai Lysholm was acceptable at all the time points (Cronbach alpha, 0.71-0.73).

Conclusion: The Thai Lysholm and Thai adjusted Tegner scales adequately retained the characteristics of the original versions. They can be considered reliable instruments for Thai patients with knee-related problems.

The aim of the present paper is to describe how the use of national quality registries (NQRs) for research has evolved over the past decade in Sweden. All Swedish NQRs have reported their scientific activity (publications per year in peer-reviewed scientific journals) to the Swedish Association of Local Authorities and Regions since 2009, and the present report is based on available data from 2009-2016. The yearly number of publications of the 69 registries active in 2009 has increased from 121 to 496 in 2016. Seventeen of these registries published more than 10 papers in 2016; however, 12 NQRs did not publish any papers in 2016. An additional 77 papers were published in 2016 by the 34 NQRs started after 2009. In summary, there has been a strong development of quality registry-based research in Sweden over the last decade. However, there is still room for further increase of the use of research based on NQRs in Sweden.

Background: Ice hockey and football players suffering concussions might have an increased risk for injuries afterwards. We aimed to investigate if concussions predisposed athletes for subsequent sport injuries.

Methods: Patient data were obtained from a data base established at the University Hospital in Umea, Sweden. Athletes who had suffered a concussion were included if they had been aged between 15 and 35 years of age, and played ice hockey, football (soccer), floorball and handball. They were studied in terms of all new or previous injuries during 24 months before and after their concussion. Results were compared with a control group of athletes from the same four sports with an ankle injury.

Results: Athletes with a concussion were more likely to sustain injuries compared with the control group, both before (OR 1.98. 95% CI 1.45 to 2.72) and after the concussion (OR 1.72. 95% CI 1.26 to 2.37). No increase in frequency of injury was found after a concussion compared with before. This was true for athletes in all four sports and for both sexes.

Conclusions: This study indicates that athletes sustaining a concussion may have a more aggressive or risk-taking style of play than their counterparts. Our data do not suggest that a concussion injury, per se, leads to subsequent injuries.

Purpose: The purpose of this paper is to investigate the obstacles and challenges associated with organizational monitoring and follow-up (M & F) processes related to health care quality improvement (QI) and development.

Design/methodology/approach: A longitudinal case study of a large health care organization during a system-wide QI intervention. Content analysis was conducted of repeated interviews with key actors and archival data collected over a period of four years.

Findings: The demand for improved M & F strategies, and what and how to monitor were described by the respondents. Obstacles and challenges for achieving M & F strategies that enables system-wide and coherent development were found in three areas: monitoring, processing, and feedback and communication. Also overarching challenges were found.

Practical implications: A model of important aspects of M & F systems is presented that can be used for analysis and planning and contribute to shared cognition of such systems. Approaches for systematic analysis and follow-up of identified problems have to be developed and fully incorporated in the organization’s measurement systems. A systematic M & F needs analytic and process-oriented competence, and this study highlights the potential in an organizational function with capacity and mandate for such tasks.

Originality/value: Most health care systems are flooded with a vast amount of registers, records, and measurements. A key issue is how such data can be processed and refined to reflect the needs and the development process of the health care system and how rich data can be used for improvement purposes. This study presents key organizational actor’s view on important factors to consider when building a coherent organizational M & F strategy.

BACKGROUND: To inform targeted prevention, we studied patterns of trauma recidivism and whether a first injury predicts the risk for a recurrent injury.

METHODS: In a population-based study of 98,502 adult injury events 1999-2012, at the emergency department of Umeå University Hospital, Sweden, we compared non-recidivists with recidivists in terms of patients' sex, age, type of injury and severity of the injury.

RESULTS: Thirty-six percent of all patients suffered recurrent injuries, which were associated with a higher proportion of inpatient care and more hospital days. Young men and elderly women were at the highest risk for trauma recidivism. At 20 to 24 years, men had a 2.4 (CI 95 % 2.3-2.5) higher risk than women, a 90 years old woman had almost a 10-fold higher risk for another moderate/severe injury than a 20 years old one. A fracture were associated with a hazard ratio of 1.28 (CI 95 % 1.15-1.42) among men younger than 65 years and 1.31 (CI 95 % 1.12-1.54) for men older than 65 years for a subsequent moderate/severe injury. For women younger than 65 years a fracture was associated with a hazard ratio of 1.44 (CI 95 % 1.28-1.62) for a subsequent moderate/severe injury. A sprain carries a higher risk for a new moderate/severe injury for both men and women and in both age groups; the hazard ratio was 1.13 (CI 95 % 1.00-1.26) for men younger than 65 years, 1.42 (CI 95 % 1.01-1.99) for men older than 65 years, 1.19 (CI 95 % 1.05-1.35) for women younger than 65 years and 1.26 (CI 95 % 1.02-1.56) for women older than 65 years. A higher degree of injury severity was associated with a higher risk for a new moderate/severe injury.

CONCLUSION: Trauma recidivism is common and represents a large proportion of all injured. Age and sex are associated with the risk for new injury. Injury types and severity, also have implications for future injury.

Background: The injury spectrum published in the literature has mainly been presented for a certain age group, as elderly or for a certain type of injury, as fracture and often restricted to in-hospital care cases. Our objective was to give an overview of the major types of injuries for all age groups and trends in the adult population.

Methods: We analyzed 68,159 adult injury events, which occurred between 1999 and 2008  and was treated at the Emergency Department of Umea University Hospital. All these injuries are registered in a database. The injuries were analyzed depending on frequency, type of injury, and activity at the time of injury. Incidence rates were calculated using population data from Statistics Sweden.

Results: Injury event incidence varied between 614 (2004) and 669 (2007) per 10,000 persons. The most common injury was a fracture, although contusions and wounds were also frequent. Fractures were responsible for almost three quarters of hospital days related to injury. The risk for fractures increased with age, as did contusions and concussions, whereas sprains decreased with age. Fracture incidence increased among the 50- to 59-year age group for both women and men. Fall-related injuries increased significantly for middle-aged adults. Sports-related and work injuries decreased, while injuries occurring during leisure time increased the most.

Conclusion: A fracture is the most frequent type of injury for adults and accounts for the largest proportion of the trauma care burden. Contusions are also common and responsible for a significant proportion of the in-hospital days. Injuries caused by a fall increased among middle-age adults imply a need for an extension of fall prevention programs.

Aim. Physical activity and physical capacity are important health related parameters for all age-groups. Yet, little is known about the relationship between physical activity and physical capacity amongst adolescents about to leave compulsory education. The aim of the study was to investigate how physical capacities are related to self-reported energy expenditure on physical activities at different levels of physical activity and amount of time spent sitting among graduates of upper secondary school. Methods. In total, 99 third grade students participated from upper secondary school. Levels of physical activity and the amount of time spent sitting were assessed using the International Physical Activity Questionnaire (IPAQ). The energy expenditure was calculated based on the activity determined by the IPAQ. The participants' physical capacity was tested using VO2max, muscle strength and balance measures. The relationship between physical activity and physical capacity was addressed using linear regression models. Results. There was significant relationship between Total METs and aerobic capacity (R2 = 0.15), push-ups (R2 = 0.08) and sit-ups (R2 = 0.07). A stronger significant relationship was revealed for activity performed on Vigorous activity METs for aerobic capacity (R2 = 0.23), push-ups (R2 = 0.18) and sit-ups (R2 = 0.10). The regression analyses for Moderate activity METs, Walking activity METs and time spent Sitting showed no significant relationship to any measures of physical capacity. Conclusion. For adolescents, the intensity of physical activity is of importance for achieving high aerobic capacity, and the amount of time spent sitting does not influence physical capacity.
