    Failure to provide ACCT training to all relevant prison staff

    Wider context from the report

    “1. ACCT Training I issued a Regulation 28 Report on 4 October 2016 in relation to a death of another prisoner at HMP Winchester ████████ concerning inter alia Assessment Care and Custody and Teamwork (ACCT) training plans and received a response from the Ministry of Justice dated 12 December 2016 in which it was stated that refresher training was taking place for 48 members of staff that month and at least monthly thereafter and that 12 new prison officers were expected to complete the Prison Officer Entry Level Training course that includes training on suicide and self-harm awareness (SASH) and ACCT process before starting work at Winchester by March 2017. In an inquest starting on 13 March 2017 in relation to a death of another prisoner at HMP Winchester ████████ evidence was given by the prison governor that at August 2016 41% of staff had received ACCT training; at the date the evidence was given 61% of staff had received ACCT training; and that the aim was for 80% of staff to receive ACCT training by Autumn 2017. The Assistant Coroner issued a Regulation 28 Report on 11 April 2017 concerning inter alia ACCT training plans and received a response from the Ministry of Justice dated 21 June 2017 which stated that at the date of the letter 120 out of 162 prison officers at HMP Winchester (74%) had received ACCT training. Evidence adduced in the inquest into the death of Mr Plumstead disclosed statistics for the provision of SASH training had been completed as follows: • As at September 2016 77.29% of forward- facing prison service staff • As at September 2016 64.27% of all prison service staff • As at September 2017 72% of forward- facing prison service staff • As at September 2017 57% of prison service staff were “in date” with such training. The evidence was that the current aim is to achieve the 80% target by mid 2018. It was apparent from the evidence that due to staff turnover, a lack of trainers qualified and available to provide such training and other priorities, targets for SASH training are failing to be met and if anything the ratio of prison staff with the appropriate skills is reducing rather than increasing. This means that the risk of prisoners at risk of self harm and suicide may not be recognised by staff who have had no such training with whom they come into contact. ”

    Inadequate storage of staff interview recordings

    Wider context from the report

    “(2) Winchester Prison has been unable to produce recordings of the interviews of staff and it has been stated that due to resourcing constraints written transcripts of some of the interviews were not prepared. It is uncertain whether the relevant assistant governor will be able to give live evidence of the results of her investigation and one of the officers involved is on long term absence. The systems in place for proper storage of such recordings appear to be inadequate and the administrative processes for transcription are insufficiently resourced. ”

    Emergency cell bell system lacking call prioritisation and activation-time identification

    Wider context from the report

    “3. Emergency Cell Bells The emergency cell bell (ECB) in Mr Plumstead’s cell had been activated by his cellmate but the response to this took 10.5 minutes whereas the expected response time is 5 minutes. The evidence showed that there was and continues to be widespread misuse of ECB’s by prisoners particularly those on general wings, which leads to prison officers responding on occasions over an hour after the ECB has been activated. There are only limited sanctions available for enforcement of the proper use of the system by prisoners. The system allows no means of prioritising calls or identifying the time when the ECB has been pressed. Prisoners who have a genuine emergency have no alternative means of requesting assistance and therefore the risk is that there medical emergencies will not have a timely response and further deaths in such circumstances will occur. The current system is not fit for purpose and notices to prisoners are ineffective. ”

    Failure to retain important documents or electronic material with specific prisoner records

    Wider context from the report

    “(3) This is not the first death in custody at Winchester Prison where potentially important documents or electronic material has been mislaid or not found because they have not been retained with specific prisoner records. There is therefore a risk that future deaths at the prison occur when such omissions are repeated. ”

    Failure to train all prisoner-facing Carillion staff in self-harm and suicide prevention

    Wider context from the report

    “2. Training of All Prisoner-facing Staff The investigation into the death of Sean Plumstead, including evidence heard during the inquest, has highlighted matters of concern relating to Carillion’s past and present operations at HMP Winchester and possibly at other establishments nationally. The evidence showed that in the 18 months before Mr Plumstead’s death in September 2016, at least two Carillion staff were employed in prisoner-facing roles at the prison (in the Clothing Exchange Store) without any training in self-harm/suicide prevention (in apparent contradiction to the national policy - the Prison Service Instruction 64/2011 in its latest version). Further, one of those staff members was expected to make entries in an (ACCT) support document without having had relevant training. As of October 2017, one of those staff members has still to be trained in self-harm/suicide prevention. It remains unclear whether the (Carillion) Works Manager and other Carillion supervisors (at a local and national level) are aware of the issue. The prison have since assumed the responsibility for the training of all staff in prisoner-facing roles but there is, as yet, no clarity on the obligations and assumptions which Ministry of Justice and Carillion were operating at the material time (2015-2016) nor indeed what arrangements will pertain in the future. Indeed, I have also heard evidence that the prison do not hold training records for Carillion staff. There is therefore some division of responsibility between the prison and Carillion and a risk that training of staff is missed because of the absence of such records. I consider there is a risk arising from my investigation that there was and continues to be a gap in training which Carillion is either unaware of or unconcerned with - a gap that may continue here and elsewhere. I understand that Carillion has a contractual obligation to ensure that staff provided to the prison will be appropriately trained, but I cannot identify any requirement for self-harm/suicide management training, nor any commitment by Carillion to make staff available for such training by the prison as necessary. The apparent ambiguities in the arrangement could compromise the safety of prisoners that Carillion personnel are dealing with. I am also concerned of a risk in other prisons, where Carillion staff are directly engaging with prisoners without adequate or appropriate training in suicide and self-harm management. I invited Carillion to be an Interested Party to the inquest, a request which they declined to take up. Nevertheless, following the evidence in the inquest, the prima facie concerns have hardened. I consider Carillion has the power to take action to remedy these shortcomings and that in collaboration with the Ministry of Justice both can address these concerns and clarify responsibilities. ”
