Marathon fundraising

The 2013 London marathon is in less than a week’s time. The hard slog of training behind them, most runners will be easing up, resting their legs before the real thing. Over the last few months, many will have sought training tips to improve their running, but what about the thousands of runners who are using the London marathon as a way of raining money for charity? What are some of the top tips for how they can achieve a fundraising personal best?

David Reinstein from Essex University has started an interesting discussion of research that fundraisers might find relevant. At CMPO, we have also begun looking at the rich data available from online fundraising website Justgiving.com to gain further insights into charitable fundraising.

The good news for marathon runners is that they have chosen a good event. Compared to fundraisers doing other events – cycling, parachuting, birthdays and other running events – London marathon fundraisers tend to have more donors (29 is the typical number) and raise more money overall (between £800 and £900 is typical).

Most marathon pages have a fundraising target. This seems to work. Compared to having no target, pages which specify a target amount get more donations and higher average donations. Donors clearly respond to the target – when the total amount raised gets close to the fundraiser’s goal, donors increase their donations to hit the target, but they give less once the target has been reached. With this in mind, raising the target could be one way to keep donations high.

Donors are also responsive to how much others have given. Arriving at a fundraising page, each donor can see how much other people have given and this information affects how much they give. A generous donation to a page – particularly made early on – can have a positive effect on later amounts given. Our results suggest that a one-off donation of £100 leads to around a £10 increase in the amounts given subsequently. Some of the effect comes through the fact that this kind of large donation triggers other people to match it; but there is also a wider, positive effect. Small donations, on the other hand, result in subsequent donors giving less. So, fundraisers have an additional incentive to encourage their friends, family and colleagues to be generous because of the knock-on effect that donations have on how much other people give.

Most people raising money by running in the London marathon will be relying on donations from their friends, family and colleagues. One question that Kimberley Scharf and I are looking at is how important the size of the person’s social group is – and whether you can be a successful fundraiser even if you have a relatively small social network. We capture the size of a fundraiser’s social network by the number of their Facebook friends. This may not be a perfect measure of the potential donor pool but many fundraisers do post to their Facebook pages. We find – perhaps surprisingly – that larger social networks do not translate into higher total amounts raised. Although fundraisers with more friends tend to get more donations, each donor in a large social network typically gives less, meaning that the total amount raised is roughly the same for those with a thousand-plus friends as it is for those with less than a hundred. This is true controlling for age and income and is also true for pages without a target.

There are a number of explanations for why this might be the case. One possibility is that, in a larger group of donors, each person’s donation matters less to the fundraiser and so the donors give less. It may also be the case that there are weaker relationships between the fundraiser and their friends in larger social networks. By digging further into the fundraising data, we hope to get a better understanding of the relationships between fundraisers and donors and provide further insights into what determines fundraising success.

Free to choose?

Free to choose?

Greater choice and competition in healthcare is a popular reform model. This column discusses recent research suggesting that once restrictions on choice in the UK’s NHS were lifted, patients receiving cardiac surgery became more responsive to the quality of their care. This saved lives and gave hospitals a greater incentive to improve quality.

A central plank of the NHS reforms implemented by the UK Labour government of the 2000s was the introduction of patient choice. For the first time in the history of the NHS it was mandated that patients should have a say in the choice of hospital when being referred for an elective treatment. Rather than relying entirely on their general practitioner (GP), patients were now offered a set of five hospitals to choose from. At the same time, GPs were no longer tied to a particular hospital through selective contracting agreements and could refer patients more easily to any available hospital in the country. The intention behind the reform was to make referrals more responsive to hospital quality. The argument was that this in turn would increase hospitals’ incentives to improve quality. Although most economists subscribe to the idea that more choice always constitutes an improvement, things are slightly more difficult in the case of healthcare. Contrary to most consumer goods markets, evaluating hospital quality is not a trivial task, and patients might indeed find it hard to pick the best hospital for a particular treatment. This is presumably even more of an issue in the UK, where patients are not accustomed to makingchoices in the context of healthcare.

Do referrals respond to quality?
We set out to analyse whether referral patterns did indeed become more responsive to quality after the introduction of the reform (Gaynor, Propper and Seiler 2012). As a first test for whether this is the case, we analyse whether relatively better hospitals attracted a larger number of patients for one particular procedure: elective coronary artery bypass graft (i.e., heart bypass surgery). We look at the relationship between hospital quality, as measured by patient survival rates, and market shares separately for the time periods before and after the reform. Interestingly, we find that market shares are not correlated with hospital quality pre-reform, however they show a significant correlation with patient survival in the post-reform period. This gives us a first piece of evidence suggesting that patients were indeed allocated to relatively higher-quality hospitals after the reform (but not before). The magnitude of the effect of quality on market shares is economically significant. Post-reform, a one percentage point lower mortality rate led to the hospital attracting 20 more patients every year. This corresponds to about a 5% increase in market share.

In a second step we model patient behavior at a more micro level. Instead of analysing only aggregate shares of patients at each hospital, we model hospital choice individually for each patient. This allows us to incorporate the effect of the patient’s location relative to the hospital as well as to analyse how reactions vary across different patient groups.

We find, also at this level of analysis, that patients became more sensitive to the quality of service as measured by patient survival. However the effect differs substantially across patient groups. Our results show that more severely ill patients react more strongly to the reform, i.e. they are even more likely than the average patient to end up at a high-quality hospital post-reform. In other words, we see the reform having the strongest effect for the group of patients that is presumably most in need of high-quality treatment. Similarly, we find a stronger effect of the reform on patients who reported in a survey that they were informed about the choice reform at the point of referral.

Finally, we also analyse whether poorer patients reacted differently to the reform. A major concern of skeptics of the reform was that only affluent, well-educated patients would be able to process the necessary information and make an educated choice. According to this logic the reform would therefore effectively increase inequality in quality of healthcare. Our analysis however, shows that fortunately these concerns were unfounded. We find that poorer patients reacted no differently from other income groups to the introduction of choice. They did indeed react slightly more strongly, but the difference is not statistically significant, i.e. we cannot confidently tell it apart from noise in our data.

Methodology
We then employ our statistical estimates to quantitatively evaluate the impacts of the reform. We perform the following thought experiment. We compare the actual hospital choices patients made post-reform with the hypothetical choices the same set of patients would have made prior to the reforms, i.e., had referral patterns not changed in response to the freeing of choice. Because we know the sensitivity of referrals to quality pre- and post-reform, we can calculate the probability of visiting each hospital that is available to the patient under either level of responsiveness to quality. Artificially depriving patients of the benefits of the reform allows us to see to what extent patients would have ended up in lower quality hospitals in the absence of patient choice. Using the hospitals’ patient survival rates (adjusted for differences in case-mix, i.e. the severity of the cases treated at each hospital) we find that nine fewer patients (relative to slightly over 300 deaths a year, i.e. around 3%) would have survived every year had the reform not been implemented.

Unexpected drop in mortality rates
The drop in mortality post-reform is an important effect of the introduction of patient choice that was not emphasised by policymakers. Even if the increased responsiveness of referrals to quality did not change hospitals’ performance in any way, the reallocation of patients still leads to better health outcomes. This is due to the fact that patients now visit on average a higher quality hospital from the existing distribution of quality across hospitals.

The hope of the reform was that the quality distribution itself would change due to hospitals’ increased incentives to improve quality in order to attract patients. We next analyse whether there is reason to believe that such a change in hospital quality might have happened. To get a sense of the effect of the change in referrals on hospitals, we compute the change in patient admissions to each hospital if patients had been choosing their hospitals pre-reform according to post-reform referral patterns. This thought experiment – what would have happened had the reform been adopted earlier – gives us a direct sense of how much competitive pressure hospitals found themselves facing when the choice reform kicked in. When calculating the change in market shares we find a very substantial impact for some hospitals, with one hospital losing almost 10% of its market share due to the effects of the reform. There is substantial heterogeneity in the impacts across hospitals however, with most hospitals experiencing more modest changes in market share of around 2% or 3%. There is therefore good reason to believe that at least a significant subset of hospitals had substantial incentives to improve quality in order to retain (or enhance) their market shares of patient admissions.

Do hospitals pay attention to the new system?
In a final step we directly analyse whether there is any evidence of hospitals reacting to the change in referrals by increasing quality, as measured by a fall in mortality rates. To this end we look at whether hospitals that faced the strongest pressure post-reform (as measured by the potential loss in admissions) saw a bigger decline in their mortality rates than other hospitals. We do indeed find that this is the case. Hospitals which had the biggest increases in the responsiveness of patient admissions to their mortality rates had the largest declines in mortality rates, and vice versa. This result closely mirrors related work by Cooper et al. (2011) and Gaynor et al. (2012) who show that areas with more competition experienced a larger increase in patient survival rates after the introduction of patient choice.

In summary, we assess that the reform reduced cardiac bypass surgery mortality by 3% by re-allocating patients to better hospitals. This is clearly a lower bound on the beneficial effect one might expect from allowing choice, as we look only at the effect for one particular procedure. Secondly, we find evidence suggesting that hospitals responded to increased choice by improving their quality. If this is mirrored as a hospital-wide effect, there may be substantial additional positive benefits for patients. Finally, our findings add support to earlier evidence that indicate that the choice reforms led to falls in mortality in other treatments and shorter lengths of stay without increasing hospital total costs (Gaynor et al., 2012; Cooper et al., 2011) and also to work by Bloom et al. (2010) that indicates that more competitive environments have better management practices that are in turn associated with better hospital performance.

On the benefits of competition in healthcare

February 27, 2012 3 comments

Governments faced with rising costs and growing demand are constantly searching for methods of delivering higher productivity in healthcare, or put more simply, ways of getting higher quality without increasing expenditure. The Health and Social Care Bill currently being voted on in the House of Lords has placed considerable weight on the encouragement of choice and competition.  Critics of the Bill are vociferous in arguing that a focus on choice and competition is, at best, misguided and, at worst, will lead to the whole-scale privatisation of the NHS.

In fact, a cool look at both the evidence gives a more positive picture.

First, there is the evidence from the ‘Choose and Book’ reforms of the last Labour administration. Implemented in 2006, these mandated that patients be allowed to choice from up to 5 hospitals for their treatment, and so introduced competition between healthcare providers. The evidence from these reforms broadly suggests the following.

It is clear that not all patients were offered choice, wanted it or took it up when offered. But it also appears that by 2009 around half of patients recalled being offered a choice. Hospitals rated as better – both in terms of some measures of clinical quality and in terms of having lower waiting times – before the policy reform attracted more patients and patient from further away after the reform. This suggests that the choice agenda had some effect on the selection of hospitals. More patients chose – with the help of their GPs – to go to better hospitals. Fears that patients would only choose on the basis of car parking or factors unrelated to clinical quality also appear to be ungrounded.

Did this movement of patients have any effect on outcomes? There is no systematic evidence that the choice agenda harmed patients. A study of equity post reform did not find that patients from more deprived local areas feared worse.  And recent studies have found positive news. Hospitals located in areas where patients had more choice had greater improvements in clinical quality (measured by lower death rates following admissions) and greater reductions in lengths of stay post policy than hospitals located in less competitive areas. What’s more, the hospitals in competitive markets increased their quality without increasing total operating costs or shedding staff. While reductions in death rates are a pretty crude indicator of quality and are contested, they are also used by health care regulators in many countries as a measure of hospital performance.

Second, there is evidence from the wave of mergers that the Blair administration undertook when it first came to power. Around half the acute hospitals in England were involved in a merger between 1997 and 2003. A recent study of these mergers has shown that, just as in the private sector, most of these did not realise the gains that were promised before the merger.  As mergers tend to reduce the potential for competition in a local market, these findings too suggests that there are benefits from competition in an NHS type system.

Third, findings from a recent study of management in the NHS shows that better management is associated with better outcomes in NHS hospitals and that management tends to be better where hospitals compete with each other.

Finally, from elsewhere in Europe there is also evidence which broadly supports competition. The Netherlands has had a mixed system of provision for many years and has slowly introduced competition. There is no evidence that this has massively harmed equity and is thought to have led to improvements in service delivery. In Germany and Switzerland, where providers are both public and private, the government has sought to increase competition between them.

In sum, the arguments may be more nuanced than many politicians (and perhaps health commentators) would like.  But there is no evidence from recent studies of the UK that allowing patients more choice and exposing poorly performing hospitals to the threat of their patients choosing another provider is going to lead to the whole-scale destruction of the NHS and large equity issues. On the contrary, the evidence we have to suggests that it has the power to improve outcomes for patients.

To Profit, or not for profit?

Michael Sanders

As part of David Cameron’s commitment to building a “Big Society”, as well as to engaging in some of the most sweeping cuts to public spending in living memory, there has naturally been discussion about the outsourcing of public services to private-sector organisations.

At one end of this debate is a discussion about whether any non-governmental organisation should be involved in the delivery of vital public services. At the other, perhaps more reasonable end of the debate, is a discussion about what kind of organisations should step in to fill the gap left by the state’s withdrawal from service provision – in particular, whether these organisations should be allowed to make a profit.

In education, Michael Gove, the secretary of state, is quoted in this week’s economist[1] as saying “We don’t need the profit motive”, in what may well be regarded by some as a statement of political convenience more than firmly-held belief. Nick Seddon, from Reform, a think-tank, has said “It’s a fallacy to think you can choke off the profit motive without losing momentum and innovation”.

The evidence is somewhat less certain that Mr Seddon makes out. Two large areas of spending where the government stands accused either of outsourcing to private firms or conspiring to are Education and Health, where great weight is put on the tendency of the best practitioners to “go the extra mile”, be that in the form of higher quality pastoral care or extra tuition in schools, or unpaid overtime and a superior bedside manner in hospitals. In both cases, the provision of the extra-mile of care is time consuming and often uncompensated. Evidence from researchers at the CMPO (Gregg et al (2008))[2] , suggests that in non-profit “caring” environments, workers provide on average 75 minutes extra unpaid overtime a week than do their colleagues in for-profit caring firms.

Sloan (2000)[3], in his comprehensive review of ownership forms for hospitals in the United States, found that for-profit and not-for-profit hospitals were more alike than different across a number of dimensions. Importantly for the claim that ‘innovation’ would disappear along with the profit motive, he finds (although evidence is relatively sparse), that the rate at which hospitals adopt new technologies is influenced by the extent to which they are competing with other hospitals for patients, but not by their ownership type (for profit vs. not for profit).

If it is not obvious that not-for-profit hospitals or schools would perform worse (or indeed, differently), than profit-making counterparts, this may be driven by the similarities between the people running them. Glaeser and Schleifer (2001)[4] model the utility functions for individuals forming not-for-profit firms as the same as individuals starting for-profit companies. As not-for-profits are more trusted (as the response to the government’s plans would seem to suggest), a utility maximising agent may find it preferable to run a not-for-profit “free-school” or academy, and to extract their utility in the form of perks; more control over the curriculum and timetable than in a standard school, and more “Warm Glow” from having contributed something to society. In a hospital context, this resembles the possibility of “cartels” of doctors running (not-for-profit) hospitals efficiently so as to maximise their own utility, as suggested by Sloan.

In summary, the potential hazards of not-for-profit ownership of public services, when compared with for-profit ownership, may be overstated. This appears to be a confusion of the ‘profit motive’ for an ‘efficiency motive’ – there is evidence suggesting that the latter may be achieved without the former, and that not-for-profits have a lower incentive to sacrifice non-contractible quality for more profit. Perhaps, on this occasion, Mr Gove is correct.

Price competition to be (re)introduced in the NHS

January 8, 2011 Leave a comment

Carol Propper

The Government has announced is to permit hospitals to compete on price. This dramatic shift towards a more commercial market in the NHS is announced in a single paragraph in the NHS Operating Framework for 2011-12 published last week.  Paragraph 5.43 says: “One new flexibility being introduced in 2011-12 is the opportunity for providers to offer services to commissioners at less than the published mandatory tariff price, where both commissioner and provider agree.”  It adds: “Commissioners will want to be sure that there is no detrimental impact on quality, choice or competition as a result of any such agreement.”

This problem with this innocuous sounding paragraph is that we have been here before and it doesn’t work.  The reason is that in health care, prices are easy to observe, whilst quality is not.  In these circumstances, health care commissioners and sellers, despite the hopes of the Operating Framework, end up focusing on price, raising the prospect of two-for-one deals on surgery and cut-rate consultations for certain specialties. At the same time, in order to provide services at these prices, quality suffers.

Research from CMPO showed this is precisely what happened in the internal market of the 1990s, where price competition was allowed.  Hospitals facing more competition focused on bringing down costs and lowering waiting list in order to provide what their commissioners wanted. But this was at the expense of quality and the consequence was that patients in hospitals located in competitive markets were more likely to die after an admission following a heart attack. These kind of unforeseen consequences are ikely to happen again – especially now when budgets are tight.

In making this move, Andrew Lansley is ignoring all the evidence on the impact of price competition in the hospital sector and is potentially endangering patients lives.

Healthcare competition saves lives

Governments faced with rising costs and growing demand are constantly searching for methods of delivering higher productivity in health care, or put more simply, ways of getting higher quality without increasing expenditure. One currently favoured mechanism is to encourage competition between the suppliers of care. But will this work? The appeal is simple – competition works in the rest of the economy therefore it should work in health care.

Unfortunately for politicians, the simple appeal does not necessarily translate across sectors of the economy.  There is, in fact, no strong theoretical support for competition in healthcare leading to better outcomes:  the predictions of economic theory on this issue are quite ambiguous (1). However, under certain condition, theory models do support competition: this is when prices are fixed by government and hospitals compete in terms of quality.

Testing this theory is often difficult, because competition in health care markets is endogenous to quality. The presence of a high quality hospital may mean that competitors stay out of its market. Or hospitals which are cutting edge tend to be located in urban areas and also attract sicker patients. In both of these situations it will appear that competition is associated with lower quality.  Dealing with this statistically is not easy without some kind of natural experiment, as case mix is very difficult to measure precisely.

The English National Health Service (NHS) is subject to frequent policy change as politicians use health care as part of their drive to win supporters. The last Labour administration introduced competition between health care providers as part of its drive to increase productivity in health care. In 2006 the government mandated that all patients must be offered the choice of five, and by 2008 any, hospital in the NHS for their treatment. In addition, the prices that hospitals could charge were fixed by the government in a ‘yardstick competition’ type regime.

This policy change provided a natural experiment that researchers could exploit. Hospitals compete in geographical markets because patients prefer to be treated, inter alia, closer to home. Hospitals thus vary in the extent to which they face competitive forces simply because of geography.  Exploiting this fact allowed researchers to look at outcomes pre- and post- the competition policy across different markets.

The research looked at all admissions to hospitals in the NHS – around 13 million admissions – pre- and post-policy.  It found that hospitals located in areas where patients have had more choice since the NHS reforms had higher clinical quality – as measured by lower death rates following admissions – and shorter lengths of stay than hospitals located in less competitive areas.  What’s more, the hospitals in competitive markets did this without increasing total operating costs or shedding staff.  These findings suggest that the policy of choice and competition in health care can have benefits – quality in English hospitals in areas in which more competition is possible has risen without a commensurate increase in costs (2).

One reason that the policy may be having this impact is the fact that prices are externally fixed. Research for the UK showed that when competition was introduced in the early 1990s in a regime that allowed hospitals to negotiate prices as well as quality there was a fall in clinical quality in more competitive areas. Waiting lists, however, declined for these hospitals.  This is supported by economic intuition.  Where quality is hard to observe, the elasticity of demand will be low. Waiting lists on the other hand are easy to observe. Buyers of health care will therefore have a greater elasticity of demand with respect to the latter than the former and so suppliers will tend to compete on the latter and on price, whilst shaving the less well observed clinical aspects of quality (3).

These results suggest that the details of the policy matter. Competition under fixed prices appears to have beneficial results whilst competition where hospitals bargain over price and quality do not.  This in turn has policy implications for governments who are keen on market forces in health care.  If competition is to work, price regulation has to be retained.  A free-for-all in prices would mean a return to the “internal market” of the 1990s, a regime in which hospitals competed vigorously on waiting times and ignored aspects of quality that are more difficult to measure. In addition, the tendency of the UK government to merge failing hospitals needs to be looked at carefully. Mergers are popular with finance ministries in NHS type systems because they remove what is often seen as ‘excess capacity’. However, while there are gains from removing poor managers when a hospital fails (4), removing capacity by merger will limit the extent of competition and may stifle the impetus given by competitive forces to improve outcomes for patients.
