Discussing risks and benefits of treatments or care options is becoming an increasingly important part of modern health care. This paper reviews the literature about manipulations of risk and benefit information in the clinical setting. There is a paucity of evidence in this field, particularly when examining specific manipulations. Only three categories of manipulation had three or more studies. The available evidence shows that the way information is presented can have significant effects on decisions made. The largest effects are evident when relative risk information is presented, as compared with absolute risk data. In addition, "loss framing" is more effective in influencing screening uptake behaviors than "gain framing" (odds ratio 1.18 [95% confidence interval 1.01-1.38]). There is also a pattern of evidence from studies comparing simpler with more complex information, more data with less, and those comparing numerical with verbal descriptions of risks. These studies suggest that providing more information, and which is more understandable to the patient, is associated with improved patient knowledge and a greater wariness to take treatments or participate in trials. These findings can contribute to efforts to improve communication between professionals and patients.

Computer users' postures and associations with workstation characteristics.

This investigation tested the hypotheses that (1) physical workstation dimensions are important determinants of operator posture, (2) specific workstation characteristics systematically affect worker posture, and (3) computer operators assume "neutral" upper limb postures while keying. Operator head, neck, and upper extremity posture and selected workstation dimensions and characteristics were measured among 379 computer users. Operator postures were measured with manual goniometers, workstation characteristics were evaluated by observation, and workstation dimensions by direct measurement. Considerably greater variability in all postures was observed than was expected from application of basic geometric principles to measured workstation dimensions. Few strong correlations were observed between worker posture and workstation physical dimensions; findings suggest that preference is given to keyboard placement with respect to the eyes (r = 0.60 for association between keyboard height and seated elbow height) compared with monitor placement with respect to the eyes (r = 0.18 for association between monitor height and seated eye height). Wrist extension was weakly correlated with keyboard height (r = -0.24) and virtually not at all with keyboard thickness (r = 0.07). Use of a wrist rest was associated with decreased wrist flexion (21.9 versus 25.1 degrees, p < 0.01). Participants who had easily adjustable chairs had essentially the same neck and upper limb postures as did those with nonadjustable chairs. Sixty-one percent of computer operators were observed in nonneutral shoulder postures and 41% in nonneutral wrist postures. Findings suggest that (1) workstation dimensions are not strong determinants of at least several neck and upper extremity postures among computer operators, (2) only some workstation characteristics affect posture, and (3) contrary to common recommendations, a large proportion of computer users do not work in so-called neutral postures.

The effectiveness of one-to-one risk communication interventions in health care: a systematic review.

OBJECTIVES: To assess whether risk-communication interventions are associated with changes in patient knowledge, attitudes, and behaviors, and to identify aspects of these interventions that modify these effects. DESIGN: Systematic review. DATA SOURCES: 96 studies from the period 1985-1996 retrieved by electronic searching of eight databases, hand searching of four journals, contacting key authors, and reference list searching. MAIN OUTCOME MEASURES: The effect size of the principal outcome was identified from each study. Outcomes measuring behavioral change were preferred; if these were not available, knowledge, anxiety, or risk perceptions were used, according to the focus of the study. Data were available to calculate the principal effect sizes for 82 of the studies. ANALYSIS: Meta-regression. RESULTS: The methodologic qualities of the studies varied. Nevertheless, risk-communication interventions generally had positive (beneficial) effects. Interventions addressing treatment choices were associated with larger effects than were those in other contexts, such as prevention or screening. Interventions using individual risk estimates were associated with larger effects than were those using more general risk information. Two design variables were identified as effect modifiers: randomized controlled trials were associated with smaller effects than other designs, and dichotomous outcomes were associated with larger effects than continuous outcomes. CONCLUSIONS: Risk communication interventions may be most productive if they include individual risk estimates in the discussion between professional and patient. Patient decisions about treatment appear more amenable to change by these interventions than attendance for screening or modification of risky behavior.

How should effectiveness of risk communication to aid patients' decisions be judged? A review of the literature.

Risk-communication interventions are associated with benefits at both the individual and the public health level. However, the types of outcomes used to assess the effectiveness of risk-communication interventions vary greatly. This makes synthesis of the research in systematic review difficult, and limits both the implementation of advances in clinical practice and further research. This article reviews the outcomes used in risk-communication publications, particularly those addressing individual decisions about treatment. From the traditional cognitive and behavioral research outcomes of patient knowledge, risk perception, and compliance, the emphasis has shifted towards more affective outcomes, including satisfaction, assessment of the information provided and the decision-making process, and certainty about whether the best option has been chosen. These affective outcomes may be more specific and sensitive measures for risk-communication research. Further development and validation of measurement scales to address these issues is needed.

Patellofemoral pain syndrome. A critical review of the clinical trials on nonoperative therapy.

Many therapies have been advocated for treating patellofemoral pain, which suggests little consensus on optimal treatment. We reviewed the high-quality evidence for successful treatment of patellofemoral syndrome based on successful outcome information. To achieve this goal, we undertook a systematic search and critical appraisal of the literature on patellofemoral pain syndrome. Our definition of patellofemoral pain syndrome was broad and included patients with cartilage damage. We found five randomized controlled trials and some follow-up studies. The prognoses for most new cases of patellofemoral pain syndrome are good, although a proportion of patients with this syndrome will have persistent symptoms. Quadriceps muscle exercises were effective in treating this condition, and knee braces were not. Both prostheses and intramuscular glycosaminoglycan polysulfate had encouraging results for patients; however, these results need confirmation. There were many studies of biomechanics, which indicates that there is an assumption that an alteration of abnormal biomechanics would result in clinical benefit. Studies are needed that place more emphasis on the therapeutic benefit. There is limited evidence on which to base therapy, and there needs to be more high-quality research. Studies need to be longer, account for factors that predispose the patients, and have a more standardized means of assessing outcomes.

Autonomic dysfunction in patients with human immunodeficiency virus infection.

Autonomic function tests have been recorded in 40 male homosexual patients with serum antibodies to human immunodeficiency virus (HIV) and 12 male homosexuals without such antibodies. Abnormalities of autonomic function were found in 15 of 31 patients without other recognized reasons for autonomic dysfunction. Four patients had two or more test abnormalities. The profile of these abnormalities was found to be different from that of autonomic neuropathy associated with diabetes and other disorders and was consistent with the presence of sympathetic overactivity. Abnormalities in autonomic function were particularly associated with clinically identifiable neurological complications of HIV infection.

HIV in UK prisons: a review of seroprevalence, transmission and patterns of risk.

Prisons contain individuals at high risk of HIV infection, notably through intravenous drug use. For complex political, social and legal reasons penal institutions in the UK are unable to provide condoms and clean needles. The outbreak of HIV and hepatitis B that occurred in a Scottish prison in 1993 focused attention on the potential problems. Debate about the issue is hampered by a lack of useful information. Current data about risk behaviour and seroprevalence is reviewed, and compared with experience in other countries. Injecting drug use in prison appears to be common, and the majority who inject in prison share equipment, which can be used many times. Sexual activity may be a smaller risk factor, but does occur between men in prison. In addition, prisoners appear to have high rates of partner change between sentences. The true prevalence of HIV in UK prisons is difficult to assess, but the available data suggest it is between 0.1 and 4.5%, lower than in Southern Europe and the USA. A window of opportunity still exists to prevent further outbreaks of HIV in UK penal institutions and to maintain these low prevalence rates. Strenuous, and possibly unpalatable measures are needed now.
