And it really disappointed me that a lot of that I had to do manually. GP15mid Respondents reported that involvement with PRISM usually fell to a single individual within the practice, who would then disseminate the information to others at practice or multidisciplinary meetings. Respondents reported that they shared the PRISM information (patient lists with risk scores) within the practice through routine practice meetings. Some respondents, particularly from practices that received PRISM closer to the QOF deadline, said that they divided the list of high-risk patients among the partners and worked individually: We had another meeting then, to just discuss the patients who we were going to see. GP15mid In most practices, few staff other than those taking the lead on PRISM were reported as making direct use of PRISM. Several of the practices were short of GPs because of illness, retirement or maternity leave. Respondents were concerned that other practice staff did not have the capacity or skills to take on more patients and also reported cuts in community services and outpatient clinics. Many respondents reported in the end of study interviews that they had not accessed the PRISM data after practices completed and submitted their QOF reports. A small number of respondents said they had planned to keep using PRISM, but technical problems or lack of time meant they were no longer using it. Only two practices reported that they were still using PRISM at the time of the end-of-trial interviews. How the Predictive RIsk Stratification Model affected the way general practitioners responded to patient needs General practitioners said that the QOF process encouraged them to intervene with identified high-risk patients. They made an effort to respond with different or additional activities for the small percentage of at-risk patients they selected from the top PRISM tier. All respondents reported carrying out an extra level of review and care to fine-tune the existing treatments that these high-risk patients already received. However, they were concerned that teams did not have the resources to respond to more activity and questioned whether or not patients were actually followed up: 86 NIHR Journals Library www. So, consequently, the work had a fairly negative impact. GP08end In other instances, GPs felt that patients were already optimally managed and they used the contact to provide reassurance: Some of them we were doing everything we could and it was just telling them that we were as well. GP03end Some practices used the opportunity to inform patients about ways to better self-manage. Two practices (10 and 11) identified frequent ED attenders and discussed, with patients and family members, other ways of managing crises. Practice 19 asked the nurse to talk with patients about issues such as identifying infections, weight management and spotting early warning signs: We got these patients and tried to (take) more time in educating them. GP19end Some GPs focused on non-medical needs which could reduce the chances of a patient deteriorating, by referring patients to other care agencies and encouraging families to self-refer. However, they admitted that it was difficult to engage other services, especially if the care was preventative rather than reactive:. GP13end Practice 3 changed arrangements to allow high-risk patients to always see the GP of their choice and flagged this arrangement on their notes and for receptionists to see when arranging appointments, so patients received continuity of care. Practice 6 made up emergency drug, steroid and antibiotic packs for identified patients to use at weekends and bank holidays if they felt their health was deteriorating. So we can structure that and do it, so rather than twice daily medication, give her once daily medication and solve the problem.
