What effect have commissioners' policies for body mass index had on hip replacement surgery?: an interrupted time series analysis from the National Joint Registry for England.

BACKGROUND: Despite their widespread use, the impact of commissioners' policies for body mass index (BMI) for access to elective surgery is not clear. Policy use varies by locality, and there are concerns that these policies may worsen health inequalities. The aim of this study was to assess the impact of policies for BMI on access to hip replacement surgery in England. METHODS: A natural experimental study using interrupted time series and difference-in-differences analysis. We used National Joint Registry data for 480,364 patients who had primary hip replacement surgery in England between January 2009 and December 2019. Clinical commissioning group policies introduced before June 2018 to alter access to hip replacement for patients with overweight or obesity were considered the intervention. The main outcome measures were rate of surgery and patient demographics (BMI, index of multiple deprivation, independently funded surgery) over time. RESULTS: Commissioning localities which introduced a policy had higher surgery rates at baseline than those which did not. Rates of surgery fell after policy introduction, whereas rates rose in localities with no policy. 'Strict' policies mandating a BMI threshold for access to surgery were associated with the sharpest fall in rates (trend change of - 1.39 operations per 100,000 population aged 40 + per quarter-year, 95% confidence interval - 1.81 to - 0.97, P < 0.001). Localities with BMI policies have higher proportions of independently funded surgery and more affluent patients receiving surgery, indicating increasing health inequalities. Policies enforcing extra waiting time before surgery were associated with worsening mean pre-operative symptom scores and rising obesity. CONCLUSIONS: Commissioners and policymakers should be aware of the counterproductive effects of BMI policies on patient outcomes and inequalities. We recommend that BMI policies involving extra waiting time or mandatory BMI thresholds are no longer used to reduce access to hip replacement surgery.

Access to hip and knee arthroplasty in England: commissioners' policies for body mass index and smoking status and implications for integrated care systems.

BACKGROUND: Commissioning policies are in place in England that alter access to hip and knee arthroplasty based on patients' body mass index and smoking status. Our objectives were to ascertain the prevalence, trend and nature of these policies, and consider the implications for new integrated care systems (ICSs). METHODS: Policy data were obtained from an internet search for all current and historic clinical commissioning group (CCG) hip and knee arthroplasty policies and use of Freedom of Information (FOI) requests to each CCG. Descriptive analyses of policy type, explicit threshold criteria and geography are reported. Estimates were made of the uptake of policies by ICSs based on the modal policy type of their constituent CCGs. RESULTS: There were 106 current and 143 historic CCGs in England at the time of the search in June 2021. Policy information was available online for 56.2% (140/249) CCGs. With the addition of information from FOIs, complete policy information was available for 94.4% (235/249) of CCGs. Prevalence and severity of policies have increased over time. For current CCGs, 67.9% (72/106) had a policy for body mass index (BMI) and 75.5% (80/106) had a policy for smoking status for hip or knee arthroplasty. Where BMI policies were in place, 61.1% (44/72) introduced extra waiting time before surgery or restricted access to surgery based on BMI thresholds (modal threshold: BMI of 40 kg/m2, range 30-45). In contrast, where smoking status policies were in place, most offered patients advice or optional smoking cessation support and only 15% (12/80) introduced extra waiting time or mandatory cessation before surgery. It is estimated that 40% of ICSs may adopt a BMI policy restrictive to access to arthroplasty. CONCLUSIONS: Access policies to arthroplasty based on BMI and smoking status are widespread in England, have increased in prevalence since 2013, and persist within new ICSs. The high variation in policy stringency on BMI between regions is likely to cause inequality in access to arthroplasty and to specialist support for affected patients. Further work should determine the impact of different types of policy on access to surgery and health inequalities.

Commissioner, clinician, and patient experiences of a pre-surgical health optimisation programme - a qualitative study.

BACKGROUND: Health optimisation programmes are an increasingly popular policy intervention that aim to support patients to lose weight or stop smoking ahead of surgery. There is little evidence about their impact and the experience of their use. The aim of this study was to investigate the experiences and perspectives of commissioners, clinicians and patients involved in a locality's health optimisation programme in the United Kingdom. The programme alters access to elective orthopaedic surgery for patients who smoke or are obese (body mass index ≥ 30 kg/m2), diverting them to a 12-week programme of behavioural change interventions prior to assessment for surgical referral. METHODS: A thematic analysis of semi-structured interviews (n = 20) with National Health Service and Local Authority commissioners and planners, healthcare professionals, and patients using the pathway. RESULTS: Health optimisation was broadly acceptable to professionals and patients in our sample and offered a chance to trigger both short term pre-surgical weight loss/smoking cessation and longer-term sustained changes to lifestyle intentions post-surgery. Communicating the nature and purpose of the programme to patients was challenging and consequently the quality of the explanation received and understanding gained by patients was generally low. Insight into the successful implementation of health optimisation for the hip and knee pathway, but failure in roll-out to other surgical specialities, suggests placement of health optimisation interventions into the 'usual waiting time' for surgical referral may be of greatest acceptability to professionals and patients. CONCLUSIONS: Patients and professionals supported the continuation of health optimisation in this context and recognised likely health and wellbeing benefits for a majority of patients. However, the clinicians' communication to patients about health optimisation needs to improve to prepare patients and optimise their engagement.

What effect have NHS commissioners' policies for body mass index had on access to knee replacement surgery in England?: An interrupted time series analysis from the National Joint Registry.

OBJECTIVE: To assess the impact of local commissioners' policies for body mass index on access to knee replacement surgery in England. METHODS: A Natural Experimental Study using interrupted time series and difference-in-differences analysis. We used National Joint Registry for England data linked to the 2015 Index of Multiple Deprivation for 481,555 patients who had primary knee replacement surgery in England between January 2009 and December 2019. Clinical Commissioning Group policies introduced before June 2018 to alter access to knee replacement for patients who were overweight or obese were considered the intervention. The main outcome measures were rate per 100,000 of primary knee replacement surgery and patient demographics (body mass index, Index of Multiple Deprivation, independently-funded surgery) over time. RESULTS: Rates of surgery had a sustained fall after the introduction of a policy (trend change of -0.98 operations per 100,000 population aged 40+, 95% confidence interval -1.22 to -0.74, P<0.001), whereas rates increased in localities with no policy introduction. At three years after introduction, there were 10.5 per 100,000 population fewer operations per quarter aged 40+ compared to the counterfactual, representing a fall of 14.1% from the rate expected had there been no change in trend. There was no dose response effect with policy severity. Rates of surgery fell in all patient groups, including non-obese patients following policy introduction. The proportion of independently-funded operations increased after policy introduction, as did the measure of socioeconomic deprivation of patients. CONCLUSIONS: Body mass index policy introduction was associated with decreases in the rates of knee replacement surgery across localities that introduced policies. This affected all patient groups, not just obese patients at whom the policies were targeted. Changes in patient demographics seen after policy introduction suggest these policies may increase health inequalities and further qualitative research is needed to understand their implementation and impact.

Evaluating a pre-surgical health optimisation programme: a feasibility study.

BACKGROUND: Health optimisation programmes are increasingly popular and aim to support patients to lose weight or stop smoking ahead of surgery, yet there is little published evidence about their impact. This study aimed to assess the feasibility of evaluating a programme introduced by a National Health Service (NHS) clinical commissioning group offering support to smokers/obese patients in an extra 3 months prior to the elective hip/knee surgery pathway. METHODS: Feasibility study mapping routinely collected data sources, availability and completeness for 502 patients referred to the hip/knee pathway in February-July 2018. RESULTS: Data collation across seven sources was complex. Data completeness for smoking and ethnicity was poor. While 37% (184) of patients were eligible for health optimisation, only 28% of this comparatively deprived patient group accepted referral to the support offered. Patients who accepted referral to support and completed the programme had a larger median reduction in BMI than those who did not accept referral (- 1.8 BMI points vs. - 0.5). Forty-nine per cent of patients who accepted support were subsequently referred to surgery, compared to 61% who did not accept referral to support. CONCLUSIONS: Use of routinely collected data to evaluate health optimisation programmes is feasible though demanding. Indications of the positive effects of health optimisation interventions from this study and existing literature suggest that the challenge of programme evaluation should be prioritised; longer-term evaluation of costs and outcomes is warranted to inform health optimisation policy development.

Suicide Deaths in University Students in a UK City Between 2010 and 2018 - Case Series.

Background: There are longstanding concerns over the mental health and suicide risk of university students in the UK and internationally. Aims: This study aimed to identify risk factors for suicide among students attending universities in a UK city. Method: Suicide deaths between January 2010 and July 2018 were identified from university records. An audit tool was used to collate data from university records and coroners' inquest files. Results: A total of 37 student deaths were identified. Only 10.8% of the students had disclosed a mental health issue at university entry. There was strong statistical evidence that students who died by suicide were more likely to have been male, experiencing academic difficulties (repeated years, changing course, and suspension of studies were all associated with a 5-30-fold increased risk), and in need of financial support compared with other students. Limitations: The coroners' records were only available for around half of the deaths. Healthcare records were not available. Conclusion: Markers of academic and financial difficulty should be considered as flags to identify students at heightened risk. Whilst the relative risk associated with academic difficulties is high, the absolute risk is low. Improved disclosure of mental health issues at university registration could facilitate targeted support for vulnerable students.

Epidemiology of adult overweight recording and management by UK GPs: a systematic review.

BACKGROUND: Primary care guidelines for managing adult overweight/obesity recommend routine measurement of body mass index (BMI) and the offer of weight management interventions. Many studies state that this is rarely done, but the extent to which overweight/obesity is recognised, considered, and documented in routine care has not been determined. AIM: To identify the epidemiology of adult overweight documentation and management by UK GPs. DESIGN AND SETTING: A systematic review of studies since 2006 from eight electronic databases and grey literature. METHOD: Included studies measured the proportion of adult patients with documented BMI or weight loss intervention offers in routine primary care in the UK. A narrative synthesis reports the prevalence and pattern of the outcomes. RESULTS: In total, 2845 articles were identified, and seven were included; four with UK-wide data and three with regional-level data. The proportion of patients with a documented BMI was 58-79% (28-37% within a year). For overweight/obese patients alone, 43-52% had a recent BMI record, and 15-42% had a documented intervention offer. BMI documentation was positively associated with older age, female sex, higher BMI, coexistent chronic disease, and higher deprivation. CONCLUSION: BMI is under-recorded and weight loss interventions are under-referred for primary care adult patients in the UK despite the obesity register in the Quality and Outcomes Framework (QOF). The review identified likely underserved groups such as younger males and otherwise healthy overweight/obese individuals to whom attention should now be directed. The proposed amendment to the obesity register QOF could prompt improvements but has not been adopted for 2017.
