Views of the chairs of Scottish health boards on engagement with quality management and comparisons with English trusts

OBJECTIVE

To describe the views of the chairs of Scottish health boards on the engagement of their boards with healthcare quality and to compare them with the views of the chairs of boards of English acute trusts. The focus of the Scottish Health Boards is on providing and commissioning care, while in England the acute trusts only provide care.

METHODS

We mailed a questionnaire, based on one used in England, to the 14 health board chairs in NHS Scotland in January 2011. The results were compared with the results of a similar questionnaire given to English acute trust chairs in 2009.

RESULTS

Most chairs in Scotland (67%) prioritised oversight of quality. Quality is considered at most Board meetings (92%), taking over 20% of time for 69% of chairs. Most boards have local quality targets and feedback quality data to staff. Compared with England, boards in Scotland meet less frequently and focus less on quality (shorter discussions, less frequent data review, fewer local targets) but they are more optimistic about their board's performance.

CONCLUSIONS

Although most chairs of Scottish boards view quality as a priority, they pay less attention to it than chairs in England, possibly due to their additional role in commissioning care.

Socioeconomic differences in patient-reported outcomes after a hip or knee replacement in the English National Health Service

BACKGROUND

We investigated socioeconomic differences in patient-reported outcomes after a hip or knee replacement and the contribution of health differences beforehand.

METHODS

Our sample included 121 983 patients in England who had an operation in 2009-2011. Socioeconomic status was measured with quintiles of the ranking of areas by the English Index of Multiple Deprivation. Outcomes at 6 months were the Oxford hip or knee score (OHS or OKS) that measure pain and disability on a scale from 0 (worst) to 48 (best), and the percentage reporting no improvement in problems. Adjustment was made for age, sex, ethnicity, comorbidity, general health, revision surgery, primary diagnosis, preoperative OHS or OKS and having longstanding problems.

RESULTS

Comparing the most- with the least-deprived group, the mean OHS was 5.0 points lower and the OKS 5.4 lower. Adjusted differences, reflecting the differences in improvement in the condition, were 2.8 [95% confidence interval (CI): 2.5-3.0] on OHS and 2.4 (95% CI: 2.2-2.7) on OKS. Adjusted odds ratios for reporting no improvement were 1.4 (1.2-1.6) for the hip and 1.4 (1.3-1.5) for the knee.

CONCLUSIONS

On average, patients living in socioeconomically deprived areas had worse outcomes after surgery, partly related to preoperative differences in health and disease severity and partly to less postoperative improvement.

Relationship between patients' reports of complications and symptoms, disability and quality of life after surgery

BACKGROUND

Patient-reported complications are increasingly being used to compare the performance of surgical departments. The objectives of this study were to explore the validity of patient-reported complications and to determine their influence on patients' reports of the benefits of surgery (health gain).

METHODS

This was an observational study of patients in England who underwent hip replacement (68,391), knee replacement (77,705), inguinal hernia repair (48,199) or varicose vein surgery (16,535) during 2009-2011. Health gain was assessed with condition-specific measures of symptoms and disability (Oxford Hip Score, Oxford Knee Score, Aberdeen Varicose Vein Questionnaire), health-related quality of life (EQ-5D™ index) and a single item on the success of surgery. Adverse outcomes included four complications, readmission and further surgery.

RESULTS

There was evidence that patient-reported complications were valid. Patients with three or more co-morbid conditions reported more complications, whereas age, sex and socioeconomic status (adjusted for co-morbidity) had little, or no association. Complications were strongly associated with readmission and further surgery. Among patients reporting a complication, the Oxford Hip Score or Oxford Knee Score was about 3 points (or 15 per cent) lower than the value in patients not reporting a complication. The EQ-5D™ score was about 0·07 lower for joint replacement, 0·06 lower for hernia repair and 0·04 lower for varicose vein surgery.

CONCLUSION

Patients' reports of complications can be used for statistical comparisons of surgical departments. If the relationship between complications and health gain is causal, there is scope for improving health gain indicators after surgery by minimizing the risk of a complication.

Sociodemographic differences in the severity and duration of disease amongst patients undergoing hip or knee replacement surgery

BACKGROUND

Differences in the use of hip and knee replacement by sex, age, ethnicity or socioeconomic status may lead to differences in disease severity between those who have surgery.

METHODS

Analyses used data collected from 117,736 patients in 2009-10 via the Patient Reported Outcome Measures (PROMs) programme in England. Adjusted differences were estimated in the Oxford Hip Score (OHS) or the Oxford Knee Score (OKS), both expressed on a scale from 0 to 48, and the proportion with longstanding problems (>5 years), expressed as odds ratios (ORs).

RESULTS

Women had more severe pain and disability than men on average (difference OHS 2.3 and OKS 3.3), but less often longstanding problems. Compared with white patients, average severity was higher in South Asian patients (difference OHS 2.7 and OKS 3.0) and in black patients (difference OHS 0.9 and OKS 1.6), who also more often had longstanding problems (OR 1.40 for hip and 1.54 for knee). Patients from deprived areas had more severe disease (difference OHS 3.6 and OKS 3.3 between least and most deprived quintile).

CONCLUSIONS

There is evidence that non-white and deprived patients tend to have hip and knee replacement surgery at a later stage in the course of their disease.

Outcomes of elective surgery undertaken in independent sector treatment centres and NHS providers in England: audit of patient outcomes in surgery

OBJECTIVE

To compare characteristics of patients and outcomes after elective surgery in independent sector treatment centres (ISTCs) and NHS providers.

DESIGN

Follow-up study with outcomes reported by patients three to six months after surgery.

SETTING

25 ISTCs and 72 NHS providers in England. Population Consecutive patients undergoing hip or knee replacement (5671 in ISTCs and 14,292 in NHS), inguinal hernia repair (640 and 2023, respectively), or surgery for varicose veins (248 and 1336, respectively).

MAIN OUTCOMES

Symptoms and disability reported by patients (Oxford hip and knee scores on a 48 point scale; Aberdeen varicose vein questionnaire) and quality of life (EuroQol EQ-5D score).

RESULTS

Patients in ISTCs were healthier than those in NHS providers, had less severe preoperative symptoms, and were more affluent, though the differences were small. With adjustment, patients undergoing joint replacements in NHS providers had poorer outcomes: difference of -1.7 (95% confidence interval -2.5 to -0.9) on the Oxford hip score and -0.9 (-1.6 to -0.2) on the Oxford knee score. They more often reported complications: odds ratio 1.3 (95% confidence interval 1.1 to 1.5) for hip and 1.4 (1.2 to 1.6) for knee. There were no significant differences in outcomes after surgery for hernia or varicose veins, except that NHS patients more often reported poor results after hernia repair (1.4, 1.0 to 1.9) and additional surgery after varicose vein surgery (2.8, 1.2 to 6.8).

CONCLUSION

Patients undergoing surgery in ISTCs were slightly healthier and had less severe conditions than those undergoing surgery in NHS providers. Some outcomes were better in ISTCs, but differences were small compared with the impact ISTCs could have on the provision of elective services.

Is there value in routine screening for Cushing's syndrome in patients with diabetes?

CONTEXT

Subclinical Cushing's syndrome has been described among diabetic populations in recent years, but no consensus has emerged about the value of screening.

METHODS

We enrolled 201 consecutive patients attending our diabetes clinic and 79 controls. Patients with at least two of the following three criteria were offered screening using a 2300 h salivary cortisol test: glycosylated hemoglobin of at least 7%, body mass index of at least 25 kg/m(2), and a history of hypertension or blood pressure of at least 140/90 mm Hg. Results are expressed as mean +/- sem.

RESULTS

Mean nighttime salivary cortisol levels were similar in the two groups (8.5 +/- 1.0 nmol/liter for diabetic patients vs. 5.8 +/- 1.0 nmol/liter for controls). Forty-seven patients (23%) had a value of at least 10 nmol/liter, which was set as a conservative threshold above which further investigation would be performed. Thirty-five (75%) agreed to further testing with a 1-mg overnight dexamethasone test. Of the remaining 12 patients, 10 were followed up clinically for at least 1 yr, and no evidence was found of the syndrome evolving. In 28 patients, serum cortisol suppressed to 60 nmol/liter or less. Of the seven patients who failed this test, four agreed to a 2 mg/d 48-h dexamethasone test, with serum cortisol suppressing to 60 nmol/liter or less in all four. Three declined this test but had normal 24-h urinary free cortisol levels. No patient had clinical features of hypercortisolism.

CONCLUSIONS

The 1-3% detection rates of three recently published series have not been realized at our center where we studied a group using criteria making patients more likely to have hypercortisolism. Our results do not support the validity of screening patients without clinical features of Cushing's syndrome in the diabetes clinic.

The decision making process on public health measures related to passenger ships: the example of influenza pandemic 2009

BACKGROUND

Public health measures at sea ports have posed a challenge for public health competent authorities, especially in the context of the influenza pandemic of 2009. This paper discusses the response of authorities to notifications of infectious diseases on passenger ships and the importance of assessing the risks related to cases of influenza. It further provides options for health measures and considerations for decision making during a pandemic such as the influenza pandemic of 2009.

DISCUSSION

Prevention and control of influenza have included action taken by both competent port authorities and ships' crews. Assessing the public health risk of each event reported from ships to competent authorities at ports is important before advice is given on implementation of control measures. Public health risk assessment involves appraisal of threats to passengers and crew on board the ship as well as to the population in the community.

SUMMARY

Any public health measures taken should be necessary and proportional to the threat. Measures at ports cannot alone be effective in the prevention of the spread of a disease to the community since other means of transport play a major role. Measures taken on board ships can be effective in containing the disease. Consistent policy based on common protocols and carried out by competent authorities at local, national, European, or international levels are essential.

Preparedness for the prevention and control of influenza outbreaks on passenger ships in the EU: the SHIPSAN TRAINET project communication

Passenger ships carry a large number of people in confined spaces. A case of the new influenza A (H1N1) virus aboard a passenger ship is an expected event and would lead to rapid spread of the virus, if preventive measures are not in place. However, many cruise lines have detailed policies and procedures to deal with cases of influenza like illness (ILI). The EU SHIPSAN and SHIPSAN TRAINET projects include in their objectives guidelines for the prevention and control of communicable diseases aboard passenger ships. A literature review showed that from 1997 to 2005, nine confirmed outbreaks of influenza were linked to passenger ships, with attack rates up to 37%. It is important to establish and maintain a surveillance system for ILI aboard passenger ships, in order to systematically collect data that can help to determine the baseline illness levels. Monitoring these will enable early identification of outbreaks and allow timely implementation of control measures.

Discovering relevance knowledge in data: a growing cell structures approach

Both information retrieval and case-based reasoning systems rely on effective and efficient selection of relevant data. Typically, relevance in such systems is approximated by similarity or indexing models. However, the definition of what makes data items similar or how they should be indexed is often nontrivial and time-consuming. Based on growing cell structure artificial neural networks, this paper presents a method that automatically constructs a case retrieval model from existing data. Within the case-based reasoning (CBR) framework, the method is evaluated for two medical prognosis tasks, namely, colorectal cancer survival and coronary heart disease risk prognosis. The results of the experiments suggest that the proposed method is effective and robust. To gain a deeper insight and understanding of the underlying mechanisms of the proposed model, a detailed empirical analysis of the models structural and behavioral properties is also provided.

DI@L-log by design: an integrated tele-care communication infrastructure

A spoken dialogue system for the acquisition of type 2 diabetes mellitus (T2DM) home monitored patient data known as DI@L-log is presented. The purpose of the system is to collect weight, blood sugar and blood pressure readings from a cohort of hypertensive T2DM patients on a weekly basis using their home telephone. The recent voice-data convergence affords an arguably improved means for doctors to track patient health states at a distance in order to provide health institutions with more frequent and accurate patient profiles. Our system architecture integrates VoiceXML and the standard PSTN, with a Pan-European open source for hosting Internet telephony applications. This paper reports on recent developments in the design of DI@L-log, which aims to serve as a communication intervention that disparages the traditional paper logbook used to document readings by the patient.
