Retrospectively patient-reported pre-event health status showed strong association and agreement with contemporaneous reports.

OBJECTIVE: The unpredictability of the occurrence of illnesses and injuries leading to most emergency admissions to hospital makes it impossible prospectively to collect preadmission patient-reported outcome measures (PROMs). Our aims were to review the evidence for using retrospective PROMs to determine pre-event health status and the validity of using general population norms instead of retrospective PROMs. STUDY DESIGN AND SETTING: Searches of Medline, PsycINFO, Embase, Global Health, and Health Management information. Six studies met the inclusion criteria for the first aim, and 11 studies addressed the second aim. Narrative syntheses were conducted. RESULTS: Strong associations were found between retrospective and contemporary PROMs in 21 of 30 comparisons (correlation coefficients over 0.68) and 20 of 24 showed strong agreement for continuous measures (intraclass correlations over 0.75). Categorical measures revealed only fair to moderate levels of agreement (kappa 0.3-0.6). Associations were stronger for indices than for individual items and for shorter time intervals. The direction of differences was inconsistent. Retrospective PROMs reported by elderly patients were similar to the general population but younger adults had been healthier. CONCLUSION: Retrospective collection offers a means of assessing PROMs in unexpected emergency admissions. However, further research is needed to establish the best policy for their use

Relationship between patient reported experience (PREMs) and patient reported outcomes (PROMs) in elective surgery.

OBJECTIVE: Our aim was to see if the reporting of better experiences by elective surgical patients was associated with better outcomes (effectiveness and safety). The objectives were to: describe the distribution of experience scores and any association with patients' characteristics; determine the relationship of experience with effectiveness and with safety; and explore the influence of patient characteristics, year and provider on the relationship between experience and effectiveness. METHODS: Patients undergoing one of three procedures from 2010 to 2012 in England who completed a patient reported outcome measure (PROM) questionnaire before and after surgery and a patient reported experience measure (PREM) questionnaire. Data on 4089 hip replacement patients, 4501 knee replacements and 1793 groin hernia repairs. Regression analysis was used to examine associations between disease-specific and generic PROMs and PREMs. RESULTS: There was a weak positive association between experience and effectiveness for all three procedures (correlation coefficient with disease-specific PROMs for hip and knee replacements 0.2 and with EQ-5D 0.1 for all three procedures). The aspect of experience most strongly associated with a better outcome was the level of communication with and trust in their doctor. A higher experience score of 1 SD (about 1.5 on a 10-point scale) was associated with about 30% less likelihood of the patient reporting a complication. There was no difference between the eight dimensions of experience. All the relationships observed were consistent over time, between different types of patients (age, sex, socioeconomic status) and between providers. CONCLUSIONS: Patients distinguish between the three domains of quality when reporting their experience and outcome. If the weak positive associations between domains were shown to be causal, there would be implications for maximising performance measures for providers

Do patient-reported outcomes offer a more sensitive method for comparing the outcomes of consultants than mortality? A multilevel analysis of routine data.

BACKGROUND: Patient-reported outcome measures (PROM) might be better for comparing consultant surgeons' outcomes than mortality. OBJECTIVES: To describe variation in outcomes between consultants, compare the number of outlying consultants according to different measures, explore the effect that the hospital in which a consultant works has on their outcomes and determine the scope for improving outcomes by reducing variation between consultants. METHOD: Consultants performing hip replacement (n=948), knee replacement (1130) and hernia repair (974) in National Health Service hospitals in England in 2009-2012; disease-specific and generic PROMs and complications; fixed-effects and multilevel models to assess consultant outcomes, were all compared. Influence of patient factors and hospital factors was assessed. RESULTS: Fixed-effects models showed that most consultants are 'as or better than expected'. However, unlike with mortality, some consultants are more than three SDs 'worse than expected' according to disease-specific PROMs (2.4% for hip and 1.2% for knee replacement), generic PROMs (1.2% and 1.0%) and incidence of complications (1.8% and 0.8%). The proportion of consultants worse than expected is less with random-effects models. Controlling for hospital factors reduced the proportion further. After controlling for known patient characteristics, consultants and hospitals contribute little towards variation in patient outcomes. CONCLUSIONS: PROMs offer a more appropriate and sensitive method for comparing consultants' outcomes. The influence of hospitals must be considered to ensure comparisons are meaningful. Improvements will be achieved by shifting the distribution of consultants rather than by reducing variation between them

Can Patient Reported Outcomes (PROs) from Population Surveys Provide Accurate Estimates of Pre-Admission Health Status of Emergency Hospital Admissions?

INTRODUCTION: The use of PROs for assessing the outcomes of emergency hospital admissions requires a means of estimating patients' pre-admission health status. A possible alternative to asking patients to recall how their health was before the incident causing admission is to use estimates derived from matched samples from population surveys. Our aims were to explore the impact of different methods of matching and to compare the results with estimates based on retrospective reporting. METHODS: First, elective hip arthroplasty patients were matched to respondents to the General Practice Patient Survey using age, sex, socio-economic status and number of comorbidities. The impact of restricting matching for locality and specific co-morbidities was explored. Second, the best matching method was applied to emergency admissions for laparotomy and for percutaneous coronary intervention (PCI) after acute myocardial infarction. Data were stratified by patient characteristics. Differences in mean EQ-5D scores between the patients and matched population respondents were tested using t tests. RESULTS: Modifying the most basic form of matching by also taking locality and the specific comorbid conditions into account made no significant difference to the mean EQ-5D score for hip arthroplasty patients. Even using the most detailed matching possible, patients' mean EQ-5D score was significantly different to that of the general population for all three cohorts. The difference was greatest for elective hip arthroplasty (0.22 v 0.64), less so for emergency laparotomy (0.56 v 0.72) and least for PCI (0.79 v 0.71). This reflects hip arthroplasty patients having a long-standing condition characterised by pain and limited mobility, whereas the other two cohorts may have enjoyed reasonable health until an unexpected acute episode led to their emergency admission. CONCLUSION: Routine PRO data acquired from population surveys cannot be used as an accurate alternative to retrospectively reported PROMs by patients during their emergency admission episode

Transferring the Benefits of Water Quality Enhancements in Small Catchments

The Water Framework Directive (WFD) sets targets of "Good Ecological Status" for water bodies across the EU. Environmental regulatory authorities must undertake economic analysis of all water bodies as part of the process of drawing up catchment management plans. In this paper, we test the transferability of benefit estimates across the kinds of smaller catchments where original benefits estimation is unlikely to be undertaken on grounds of costs. This is done in a context where agricultural-source nonpoint pollution and irrigation water abstraction are the main threats to ecological status.Resource /Energy Economics and Policy,
