The creation of a professional college for policing â€“ part of the professionalisation agenda â€“ is an opportunity to work towards becoming evidence based. This is something that has been made clear to me over the last two months and something Iâ€™ve been arguing for years, incidentally! We can look around and see that the College and individual police forces are trying to engage academics to bring research skills into policing and actively build that evidence base. West Midlands Police and the Metropolitan Police are just two forces hosting research fairs and inviting academics into their organisation with the aim of understanding what works in policing â€“ and why?
Evidence is key to this â€“ being the police, we should be concerned about the standard and quality of our evidence, shouldnâ€™t we?! We are in criminal trials â€“ why havenâ€™t we been overly concerned with it terms of evaluating interventions? We see examples all around us where evidence is not being brought to bear on the claims we make â€“ again and again, I see this in policing and mental health. For example, that the Centre for Mental Health, in writing various documents about liaison and diversion services, has said, â€œthe evidence for liaison and diversion is just not there.â€ It doesnâ€™t mean there is evidence of it not â€˜workingâ€™ â€“ whatever that means â€“ it just means we havenâ€™t (yet) gathered the data to show it works. Let me show you another example of where weâ€™re not relying upon evidence.
I have repeatedly heard in the last two months that â€˜street triage is saving officer timeâ€™ and other claims implying the same. You can see for yourself in the recent HMIC report â€˜Core Businessâ€™ (2014, p116) â€“ there is clear wording that the introduction of street triage has seen average assessment times for 136 fall â€˜from eight hours to fiveâ€™. We see the same report imply that street triage has reduced the time spent dealing with the consequences of section 136 detentions and an example is given of a force where over 13,000 hours of time was spent in 2013 waiting for assessments. (This amount of time has more than doubled in two years, incidentally â€“ so we can all agree that the force concerned will want to do something about the ever-increasing tacit consumption of their resources by the mental health system.)
So does it actually save time? â€“ and is that actually the point of it?!
THE EVIDENCE FRAMEWORK
Let me firstly suggest that the evidence you would want to gather around you concerning street triage will be highly dependent upon what you see as the point of it all. If youâ€™re wondering about the time it saves you will need to know certain data; if there are other objectives, youâ€™ll need other data. To test the proposition that it saves time, you would look to gather proper evidence about time spent on s136 and time spent undertaking new â€˜street triageâ€™ approaches.
Then â€“ and only then! â€“ can you start to work out what impact street triage has had. The factors mentioned so far are only those you would need to start evaluating the impact on the police â€“ and Iâ€™ve cut short the list of things youâ€™d probably examine! I could go on and on if we start to think about the impact on health and social care. I repeat the point: you have to be asking yourself evaluation or research questions which address the issue â€œWhat are you trying to achieve by this scheme.â€ What is your objective or objectives?
WORDS AND DEEDS
This is really important to any evaluation: we need to be clear about what weâ€™re actually trying to achieve because otherwise, how do you know whether youâ€™ve succeeded? I heard recently that street triage is about â€˜reducing the use of s136 â€“ the endâ€™. Thatâ€™s fine â€“ so if thatâ€™s what youâ€™re trying to achieve, why are street triage schemes busy trying to do other things? Are they just over-resourced for their main purpose and kindly helping out with other extraneous â€˜stuffâ€™ or were they actually always there for a broader purpose? This question is really important and in no way flippant â€“ because it affects the research and evaluation questions you ask yourself in relation to which you then draw on or seek out particular quantitative and / or qualitative data.
One other area told me â€œWeâ€™re trying to reduce the use of police cells.â€ Great â€“ who could object to that? But please tell me why street triage is being done in areas that werenâ€™t really using the cells anyway? It really must be about other, broader issues, otherwise areas like Birmingham wouldnâ€™t be doing it at all â€“ there was cell no usage to reduce! Reduction in the use of the power AND a reduction in reliance upon police cells? â€“ still doesnâ€™t explain why triage services then do things that achieve neither purpose and it doesnâ€™t allow you to pose a proper research hypothesis that can be tested by proper inquiry.
If the activity of street triage schemes is undertaken somewhere other than in public streets, then itâ€™s clear we must be trying to achieve something else â€“ as well or instead. So what is it we are trying to do? That needs to be part of your evidence base as you assess these things. I admit that I personally have long since stopped judging schemes by what they say they are trying to do â€“ I look instead at what they are actually spending their time doing.
Points about mental health street triage from various areas:, they are not responding in their multi-agency vehicle to most of the incidents they are contacted about; they are â€˜dealingâ€™ with incidents (often from afar) that are two-thirds of the time being hosted in peopleâ€™s private homes; triage is seeking to avoid s136 usage but that was only ever a possibility in one-third of the incidents they attend and it seems to be occurring in areas regardless of whether the cells are being relied upon as a place of safety or not and irrespective of how that police force is perceived to be using the legislation in the first place.
So itâ€™s about some else or something far broader, otherwise they wouldnâ€™t be wasting their time on extraneous â€˜stuffâ€™. Iâ€™ll let you decide for yourself what you think itâ€™s about!
What I do know is this: a police officer works for 2,080 hours a year (without working any overtime). So we can look at the various schemes and work out how many hours and pounds are being expended in providing it. (Letâ€™s just stick with the police service, for now.) We can then look at the reductions in the use of the power and the use of the cells and work out the time and / or money saved. Letâ€™s say, that a force with 1,000 detentions per year reduced s136 use by 40%, therefore avoiding 400 instances of two officers sitting in a place of safety pending assessment by an AMHP and a Doctor.
If the average wait was four hours per detainee after the half hour that the Royal College of Psychiatry standards suggest the police should spend handing over, we can then do the maths â€”
400 (avoided detentions) x 2 (police officers per detention) x 4 (hours spent waiting per detainee) = 3,200hrs saved. If your street triage scheme requires four full time equivalent police constables to deliver this, then you are expending 8,320 hours to achieve this. If youâ€™re new improved arrangements also mean that you reduce the average wait from 4hrs to 3hrs, you can recalibrate that answer to suggest that 2,400hrs were saved, but that you also saved time for those detentions that still occured.
600 remaining detentions) x2 (police officers per detention) x 1 (hour saved by reduced waiting times) = 1,200hrs saved. So you can celebrate a total of 3,600hrs saved overall before moving on to â€˜do the mathsâ€™ for the health and social care investment, versus saving and pose that back against your new operating model.
You could also work out the custody time saved if police cells were still being used. Where a street triage scheme brought about end of custody being used as a place of safety after previously having seen 250 detentions per year in the cells, averaging 10hrs each, you can calculate the implications and therefore the cost. Half an hour of a sergeantâ€™s time saved per detainee booking them in, 5 minutes of a custody sergeantâ€™s time for every subsequent hour in custody; one consultation by a police doctor; 5 minutes for every hour in custody for a detainee to be attended to by the custody assistants and 10hrs of someone undertaking level three or level four observations in custody. Forces model this time and cost different â€“ for our purposes, Iâ€™m simply making the point that you could calculate it.
REDUCING 136 AND CELL USAGE
So if weâ€™re trying to reduce s136 usage: Great, weâ€™ve reduced it by 40% â€“ job done. But we canâ€™t claim in our hypothetical model that it has actually saved time. It is actually costing you time: because in order to save 3,600hrs overall, you are posting four FTE constables to the position and expending 8,320 hours of effort. This is a net loss totalling 4,720hrs â€“ in other words it is more than two full time officers for the area where the scheme works. Well done.
Police time is FAR from being the only important thing in these issues, however â€“ but the point Iâ€™m making is that we are claiming we need to be evidence based and claiming we save officer time when we actually seem to be spending it! But what price human dignity, less restrictive assessment options, faster responses to incidents of mental health crisis care by the health service? â€¦â€¦. ALL of these things are not easily measured in terms of hours and pounds so perhaps the emphasis should be on these positive outcomes and greater human dignity which is worth paying for (up to a point, given that budgets are finite).
I was talking to professionals today at a Crisis Care Concordat meeting asked them â€˜How many people in your area ask for urgent help whilst in crisis?â€™ (accepting that â€˜crisisâ€™ isnâ€™t defined.) No-one knew â€“ itâ€™s fair to say no-one knows in any area! But if we donâ€™t know how many attempts are made to seek crisis support, how can we tell how many of these incidents were managed correctly, at the first time of asking? How can we evaluate whether crisis demand for the police today, is failure demand from attempts to access support via the CrisisTeam earlier today or yesterday. How many people whoâ€™ve attempted to access Accident & Emergency today, had attempted to access their GP or Community Mental Health Team before self-presenting?
No-one knows. So we probably need to take crisis care back even further and ask even more fundamental questions about what weâ€™re trying to achieve before we can put street triage in itâ€™s proper context and determine that itâ€™s an answer to something â€“ but only after it is properly evaluated and we have evidence, not anecdote!
