Has payment by results affected the way that English hospitals provide care? Difference-in-differences analysis

Objective To examine whether the introduction of payment by results (a fixed tariff case mix based payment system) was associated with changes in key outcome variables measuring volume, cost, and quality of care between 2003/4 and 2005/6. Setting Acute care hospitals in England. Design Difference-in-differences analysis (using a control group created from trusts in England and providers in Scotland not implementing payment by results in the relevant years); retrospective analysis of patient level secondary data with fixed effects models. Data sources English hospital episode statistics and Scottish morbidity records for 2002/3 to 2005/6. Main outcome measures Changes in length of stay and proportion of day case admissions as a proxy for unit cost; growth in number of spells to measure increases in output; and changes in in-hospital mortality, 30 day post-surgical mortality, and emergency readmission after treatment for hip fracture as measures of impact on quality of care. Results Length of stay fell more quickly and the proportion of day cases increased more quickly where payment by results was implemented, suggesting a reduction in the unit costs of care associated with payment by results. Some evidence of an association between the introduction of payment by results and growth in acute hospital activity was found. Little measurable change occurred in the quality of care indicators used in this study that can be attributed to the introduction of payment by results. Conclusion Reductions in unit costs may have been achieved without detrimental impact on the quality of care, at least in as far as these are measured by the proxy variables used in this study.

Economic evaluation of the societal costs of hepatitis B in South Korea

Background and Aims: Hepatitis B (HBV) infection remains a major public health problem in South Korea, and accounts for considerable morbidity and mortality. At present, very little is known about the cost of HBV to the South Korean health‐care system and society. The present study was therefore conducted to estimate the total annual cost of HBV infection in South Korea for a given year (1997).

Using discrete choice experiments to inform randomised controlled trials: an application to chronic low back pain management in primary care

Pain Management Programmes (PMPs) are a multi-disciplinary approach to the management of chronic low back pain (CLBP). Notwithstanding evidence of effectiveness, successful take-up of programmes requires acceptability to patients. We used a discrete choice experiment to investigate patient preferences for alternative PMPs for managing CLBP in primary care. Specifically, we estimated the probability of uptake of alternative configurations of PMPs. Potential attributes and associated levels influencing take-up were identified through a systematic literature review, survey of current PMPs, expert consultation, and focus groups. Five attributes were included: content; provider; schedule; group size; and travel time to clinic. Four hundred and fourteen questionnaires were mailed to patients attending clinics and 124 questionnaires were returned suitable for analysis. Method of delivery influenced probability of take-up, with small group sizes and low intensity programmes over a prolonged period increasing the probabilities. Travel time was also important. However, providers and contents of PMPs were not main drivers of preferences, though those with more severe pain did prefer PMPs provided by more specialists. Probability of take-up increases when PMPs better reflect patient preferences. Given preferences, resource constraints, and evidence on clinical outcomes of alternative configurations it is suggested more resource-intensive PMPs be reserved for those with the most severe and disabling pain and less intensive programmes delivered over a longer time period in smaller groups for those with less severe pain. These findings can inform future randomised trials to evaluate acceptable PMPs in primary care.Pain Management Programmes (PMPs) are a multi‐disciplinary approach to the management of chronic low back pain (CLBP).

Gaining pounds by losing pounds: preferences for lifestyle interventions to reduce obesity.

While there is evidence that weight-loss interventions reduce morbidity, indications of their acceptability are limited. Understanding preferences for lifestyle interventions will help policymakers design interventions. We used a discrete choice experiment to investigate preferences for lifestyle interventions to reduce adult obesity. Attributes focused on: the components of the programme; weight change; short-term and longer-term health gains; time spent on the intervention and financial costs incurred. Data were collected through a web-based questionnaire, with 504 UK adults responding. Despite evidence that dietary interventions are the most effective way to lose weight, respondents preferred lifestyle interventions involving physical activity. While the evidence suggests that behaviour change support improves effectiveness of interventions, its value to participants was limited. A general preference to maintain current lifestyles, together with the sensitivity of take up to financial costs, suggests financial incentives could be used to help maximise uptake of healthy lifestyle interventions. An important target group for change, men, required more compensation to take up healthier lifestyles. Those of normal weight, who will increase in weight over time if they do not change their lifestyle, required the highest compensation. Policymakers face challenges in inducing people to change their behaviour and adopt healthy lifestyles.

The push me, pull you of financial incentives and health inequalities: a mixed methods study investigating smoking cessation in pregnancy and breastfeeding

Abstract Background Financial incentives are increasingly considered to address socially patterned behaviours like smoking in pregnancy and breastfeeding. We investigated their mechanisms of action in relation to health inequalities to inform incentive intervention design. Methods The evidence syntheses we undertook were incentive effectiveness, delivery processes, barriers and facilitators to smoking cessation in pregnancy and also breastfeeding; and incentives for lifestyle behaviours. We searched Medline, Embase, CINAHL, PsycINFO, Web of Science, the Cochrane Library (all sections), MIDIRS, ASSIA, and the Trials Register of Promoting Health Interventions for studies published in English between Jan 1, 1990, and March 31, 2012, using a range of natural language, MeSH, and other index terms. Surveys were done with 1144 respondents from the general public and with 497 maternity and early-years health professionals. Qualitative interviews and focus groups were conducted with pregnant women, recent mothers, and partners in three UK settings (n=88); and with 53 service providers, 24 experts and decision makers, and 63 conference attendees. A discrete choice experiment (DCE) was conducted with 320 female current or ex-smokers. Findings Systematic reviews raised concerns about the reach of incentives, particularly to marginalised groups. Baseline characteristics for people who were eligible, approached, and recruited to studies were under-reported. Sample sizes were mostly small. Surveys revealed mixed acceptability. Less educated, white British, and women general public respondents disagreed (odds ratios [OR] 0·5≤OR Interpretation Financial incentives can help some women, but whether they will address inequalities is unclear because of concerns about reach and resistance to being pushed and pulled.

Variations in the cost of formal and informal health care for patients with advanced chronic disease and refractory breathlessness: A cross-sectional secondary analysis:

Background: Refractory breathlessness in advanced chronic disease leads to high levels of disability, anxiety and social isolation. These result in high health-resource use, although this is not quantified. Aims: To measure the cost of care for patients with advanced disease and refractory breathlessness and to identify factors associated with high costs. Design: A cross-sectional secondary analysis of data from a randomised controlled trial. Setting/participants: Patients with advanced chronic disease and refractory breathlessness recruited from three National Health Service hospitals and via general practitioners in South London. Results: Of 105 patients recruited, the mean cost of formal care was £3253 (standard deviation £3652) for 3 months. The largest contributions to formal-care cost were hospital admissions (>60%), and palliative care contributed <1%. When informal care was included, the total cost increased by >250% to £11,507 (standard deviation £9911). Increased patient disability resulting from breathlessness was associated with high cost (£629 per unit increase in disability score; p = 0.006). Increased breathlessness on exertion and the presence of an informal carer were also significantly associated with high cost. Patients with chronic obstructive pulmonary disease tended to have higher healthcare costs than other patients. Conclusion: Informal carers contribute significantly to the care of patients with advanced disease and refractory breathlessness. Disability resulting from breathlessness is an important clinical cost driver. It is important for policy makers to support and acknowledge the contributions of informal carers. Further research is required to assess the clinical- and cost-effectiveness of palliative care interventions in reducing disability resulting from breathlessness in this patient group.

Exploring preferences for symptom management in primary care: a discrete choice experiment using a questionnaire survey.

Background Symptoms are important drivers for the use of primary care services. Strategies aimed at shifting the focus away from the GP have broadened the range of primary healthcare available. Aim To explore preferences for managing symptoms and investigate trade-offs that the public are willing to make when deciding between different primary care services. Design and setting UK-wide postal questionnaire survey of 1370 adults. Method A discrete choice experiment examined management preferences for three symptoms of differing seriousness (diarrhoea, dizziness, and chest pain). Willingness-to-pay estimates compared preferences between symptoms, and by sex, age, and income. Results Preferences differed significantly between symptoms. ‘Self-care’ was the preferred action for diarrhoea and ‘consulting a GP’ for dizziness and chest pain. ‘Waiting time’ and ‘chance of a satisfactory outcome’ were important factors for all three symptoms, although their relative importance differed. Broadly, people were more prepared to wait longer and less prepared to trade a good chance of a satisfactory outcome for symptoms rated as more serious. Generally, preferences within subgroups followed similar patterns as for the whole sample, although there were differences in the relative strength of preferences. Conclusion Despite increased choices in primary care, ‘traditional’ actions of ‘self-care’ for minor symptoms and ‘GP consultation’ for more serious symptoms were preferred. The present findings suggest, however, that people may be willing to trade between different health services, particularly for less serious symptoms. Understanding the relative importance of different factors may help inform interventions aimed at changing management behaviour or improving services.

Public acceptability of financial incentives for smoking cessation in pregnancy and breastfeeding

Are socioeconomic position, work stress, and work complexity associated to mobility after retirement?Abstracts from the ICBM 2014 Meetings from the ICBM 2014 MeetingIntroduction: Attitudinal ambivalence occurs when individuals endorse both positive and negative attitudes toward the same target object. Ambivalent attitudes are particularly relevant for addictive behaviours, as these behaviours may have both positive and negative evaluations associated with them. For example, drinking alcohol may make someone relaxed but can also produce feelings of nausea. Despite this, the majority of research focused on attitudes toward addictive behaviours assume that these attitudes are either positive or negative, not positive and negative. By assessing ambivalence toward addictive behaviours, a greater understanding of the nature of attitudes underlying these behaviours can be realised. Method: A total of 247 participants (M= 28.76 years) took part in this study. A measure of potential ambivalence, which asks participants to indicate their positive and negative evaluations on split semantic differential scales, was completed for five different health behaviours: drinking on a weekday and a weekend, exercising, increasing fruit and vegetable intake and smoking. Results: Attitudes toward alcohol consumption were found to be the most ambivalent. When examining drinking behaviour, a pattern emerged suggesting that the greater the quantity of alcohol consumed, the more ambivalent participants were toward drinking. Similar patterns were found for smoking. Conclusions: The results suggest that attitudinal ambivalence is an important aspect of addictive behaviours, as participants engaging in greater levels of these behaviours also reported higher levels of ambivalence. This indicates that individuals are aware of the positives and negatives of addictive behaviours but continue to perform them anyway.Salivary cortisol and alpha-amylase (sAA) that reflect hypothalamopituitary-adrenal axis (HPA-axis) activity and sympathetic activity within the autonomic nervous system (ANS) respectively, are bio ...Introduction: Previous research has developed an 11-item self-report measure assessing activation and pressure stress among adolescents.
