Abstract

Background

Prison health care in England, including primary care, is now incorporated into the National Health Service; the impetus for the change is in part due to concern about standards of health care within prisons. The demographic characteristics and health status of patients within prisons are relatively well understood, as are the problems faced by health care professionals. Less is known about current health care provision.

Aims

To describe the organisation of primary health care and specialised services in prisons and compare services available to different types of prison.

Method

A piloted questionnaire was sent to the governors of all prisons in England and Wales for completion by the health care manager.

Findings

Completed questionnaires were received from 122 (89%) of 138 prisons. The survey showed a low use of information technology (IT). Problems were reported with the recruitment and retention of general nurses in more than 50% of prisons. Prisoners in category A/B (higher security) prisons had available to them a greater range of health care services compared with those in other prisons. The results suggest that provision of services for chronic diseases and improvements in IT are needed. Problems with the recruitment and retention of general nurses need addressing. The reasons why lower-security prisoners are receiving a narrower range of specialised health care services compared with higher-security prisoners need justifying.

Introduction

Since April 2006 health care services in prisons in England and Wales have become part of the National Health Service (NHS) with general practitioners (GPs) responsible for medical primary care services. The delivery of health care, training for GPs and research in this setting are now therefore explicitly part of general practice as a discipline.

The move to mainstream or normalise care in prisons follows concerns about poor provision of care in prisons (Reed and Lyne, Reference Reed and Lyne1997). Policy documents relating to primary care provision within prisons stress two related themes: that patients within prisons should receive the equivalent level of care available outside and that primary care trusts (PCTs) should commission services within prisons (Department of Health and HM Prison Service, 2002; Department of Health and Home Office, 2007).

The prison population is currently about 80 261, of which 4370 are female and 12 777 are on remand (National Offender Management Service, 2007). Patients in prison are predominately male, young (White et al., Reference White and Park1999) and from areas of high deprivation (Singleton et al., Reference Singleton and Meltzer1998). Although comparisons with similar groups outside prison are not straightforward, patients inside prison are reported to have high consultation rates (Twaddle, Reference Twaddle1976), a high prevalence of chronic diseases such as asthma (Butler et al., Reference Butler and Kariminia2004) and hypertension (Olubodun, Reference Olubodun1996), greater prevalence of diseases resulting from illegal drug use such as hepatitis B and C (Butler et al., Reference Butler and Dolan1997; Maher et al., Reference Maher and Chant2004; Boutwell et al., Reference Boutwell and Allen2005) and a higher prevalence of mental health problems (Butler et al., Reference Butler and Allnutt2005). Older patients have relatively poorer health compared with same-aged groups outside prison, and the prison system is not designed to accommodate their needs (Docherty, 2007). Young offenders have greater physical and psychosocial problems compared with non-offenders of the same age (Macdonald, 2006). Female patients also have relatively poor health and distinctive health needs (Harris et al., Reference Harris and Hek2007). Patients themselves report difficulties accessing outside care, deficiencies in medical care within prisons and fears about dying in prison (Pettinari, 1996). They feel less reassured during consultations than patients outside prisons (Martin et al., Reference Martin and Russell1991).

Difficulties faced by health care staff have also been well described. These include problems concerning truthfulness in consultations (Pettinari, 1996) and working in an organisation where health care is not the main priority (Department of Health, 1999). There is a high turnover of patients (White et al., Reference White and Park1999) and currently, of sentenced prisoners, 5500 are serving sentences of six months or less (National Offender Management Service, 2007). Other problems include deficiencies in care provision outside (Birmingham, Reference Birmingham2003), professional isolation (Department of Health and HM Prison Service, 2001) and specific problems such as hunger strikes and dirty protests (smearing of faeces) (Gray et al., Reference Gray and Pearce2006). Although there is a need for provision of health-promoting services by nurses in prisons, as well as assessing need and treatment of health care problems, the organisation within prisons may make this difficult to achieve (Condon et al., Reference Condon, Hek and Harris2007). The daily routine work of doctors within prisons includes the need to quickly assess large numbers of people newly admitted to prisons, including drug withdrawal symptoms (Marteau and Farrell, Reference Marteau and Farrell2005).

Less is known about patterns of health care organisation within prisons, particularly primary care services. We undertook, on behalf of the Department of Health, to audit health care provision to prisons and to collect data about the types of prison. Our aims were to describe the nature of services within prisons and to determine what services are associated with which types of prison.

Methods

A postal survey was conducted in all 138 prisons in England and Wales, including adult and young offender institutions. The survey questionnaire was based on a questionnaire previously used to investigate the quality of care among general practices in England (Campbell et al., Reference Campbell and Hann2001), modified to be applicable for prisons by the Primary Care Research Interest Group of the National Prison Health Research Network. Included were questions about the provision of services applicable to prison populations but not usually to mainstream general practice. The full list of these is given in Table 2, and we have termed them, ‘specialised services’. The questionnaire gathered information about the number and types of primary health care staff serving in prisons and the organisation of care for five common chronic diseases – diabetes, heart disease, asthma, hepatitis and anxiety/depression – and was piloted for acceptability and clarity by health care managers at two prisons.

The questionnaire was sent to all prisons in October 2005. A written reminder was sent after three weeks. Those who did not respond within a further three weeks received one or more telephone reminders.

Statistical analysis

Individual questionnaire items were analysed descriptively. Other analyses used regression techniques to investigate service provision and health care staff support in relation to prison characteristics. These analyses utilised a number of variables constructed as below.

Specialised services provision

For each prison, provision was measured as the number of specialised services present out of the 13 (Table 2). We excluded mother-and-baby units, as these only applied to women’s prisons.

Primary care provision

We defined a ‘full’ primary care service for diabetes, heart disease, asthma or hepatitis as one with a patient register, written guidelines and a recall system – features expected of such a service outside of prison. For anxiety/depression we defined a full service to have ‘talk therapies’ and ‘self-help’ materials. Each prison was assigned a score, out of 5, based on the number of ‘full’ chronic care services it provided. In addition, each prison was assigned a score out of 7, based on the number of ‘full’ chronic care services it provided plus the existence of on-site out-of-hours care and/or an on-site pharmacy service (Table 2).

GP support

Measured as the number of GP surgeries provided per week per 100 prisoners.

Nurse support

The number of nurse sessions provided per week per 100 prisoners. A ‘session’ pertains to half-a-day, with a full-time nurse working for 10 sessions a week. In all, 79 (65%) prisons provided reliable data on nurse sessions. We used the mean number of sessions per nurse for this group to impute session numbers for another 36 (30%) prisons that reported nurse numbers but not sessions per se.

The prison characteristics were:

Size of prison: From inspection of the distribution of prisoner numbers, prisons were divided into three categories of size: small (<400 prisoners); medium (400–699); large (700 plus).

Prison type: We classified the prisons into six types. Adult male prisoners are assigned a security category from ‘A’ to ‘D’, with ‘A’ representing the highest risk. We coded these prisons according to the prisoners presenting the highest security risk (remand prisoners are classed as category ‘B’). Female prisoners and young offenders are not security classified. We therefore treated women’s prisons and young offender institutions as two further distinct categories.

Three sets of analyses were conducted to assess: (1) the influence of prison characteristics (size and type) on the provision of specialised and primary care services; (2) the influence of prison characteristics on GP and nurse staffing levels; and (3) the influence of staffing levels on the provision of chronic disease services, both before and after controlling for prison characteristics. We hypothesised that more staff would result in better organisation of chronic disease services; therefore, this analysis used numbers of GP surgeries and nurse sessions, rather than rates per 100 prisoners.

For outcomes in the form of a count (number of specialised services, number of primary care services, number of chronic services) we applied multivariate Poisson regression. In all cases, the data showed a good fit to the hypothesised Poisson distribution. For staffing support outcomes we applied multivariate linear regression. To examine effects of prison type, we first compared all types, then if this test was significant, performed a sub-test between the four categories of adult male prison.

Prison size was missing in 24 (20%) cases, and prison type in 4 (3%). We dealt with this by treating missing cases as a separate group. This allowed us to include these prisons in the analysis, though we do not report the results for these groups. For simplicity, we excluded the single mixed-sex prison from the regression analysis.

All analyses were conducted using Stata Version 9 (Stata Corporation, College Station, TX, USA) and since this was an exploratory analysis an alpha level of 5% was used throughout.

Results

Of the 138 prisons, 122 (88%) responded in time to be included in the analysis. Basic descriptives of the sample are given in Table 1.

Figures are number (%).

bIncludes one mixed-gender prison.

Specialised services

Prisons were asked to indicate from a list which specialised services they had available (Table 2). About half reported an on-site in-patient unit with an average number of 17 beds (range 1–38). Most indicated they had available mental health in-reach team and CARATS (Counselling, Assessment, Referral, Advice and Throughcare Services). Methadone maintenance was offered by just over one-third of prisons. Prisons provided a median of 5 out of 13 specialised services, though the range was very broad with two providing none, and two providing all 13.

cPossesses a patient register, recall system and written guidelines.

dTalk therapies and self-help materials available.

Primary care services

Prisons offered a median of 5 surgeries per week (Table 3), with a minority (17%) offering 10. The most common appointment time allocation offered for routine appointments was ‘variable’ (66%) followed by ‘10 min’ (26%), suggesting a greater degree of flexibility in arrangements for numbers of patients seen in a particular surgery and perhaps also reflecting the lack of information technology (IT) (discussed below) compared with outside general practices. GP support was variable, ranging between 0.26 and 4.8 surgeries per week per 100 prisoners, with a mean of 1.6. Nursing support was even more variable; some prisons reported no nursing support and others up to 56 sessions per week per 100 prisoners (mean 14.7). Prisons with no nursing support had all nursing posts vacant at the time of survey.

a‘Don’t know’ responses excluded.

Out-of-hours care was most commonly organised via an ‘in-house’ scheme (30%), followed by a variety of PCT schemes (28%) or a deputising service (20%). In all, 37% obtained their pharmacy service from ‘another’ prison, while 25% had on-site pharmacists; community pharmacists, hospital pharmacists and others accounted for the remainder.

Only 9% of prisons described themselves as being ‘paper light’, with clinical information entered directly onto a computer – a marker of IT use. Almost all prisons could ensure transfer of medical records between prisons, but 73% had no system for transferring medical records in from the community.

More than a half of all prisons provided full diabetes and asthma services: and nearly half provided a hepatitis service; but only about one-quarter had a full service for ischaemic heart disease (Table 2). Only around a third held registers of chronic patients in an electronic form. With the exception of heart disease, around two-thirds of prisons had a designated lead for each chronic condition, usually a nurse, and about a half held special clinics. Less than a quarter of prisons had audited any of their chronic disease services in the last two years.

More than half provided both talk therapies and self-help materials for patients with anxiety or depression (Table 2). Talk therapies were delivered by a mixture of providers such as Community Psychiatric Nurses, psychologists and counsellors.

Vacancies

Although there were a large variety of different staff vacancies and eight prisons had vacancies for GPs, the major difficulty appeared to be with general nurses. In all, 64 (52%) prisons were looking for one or more general nurses to work full or part time. Across all prisons, there were a total of 200 vacancies for nurses.

Arrangements for governance and complaints

Of the 115 prisons who knew whether or not they had carried out a recent satisfaction survey, 56 (49%) had done so. Almost all stated they had leads for clinical governance and most said they had a formal system for dealing with complaints. About 80% stated they had formal meetings to discuss critical events.

Factors associated with service provision

Number of specialised services

In multivariate regression, specialised service provision was related to both prison type (P < 0.001) and prison size (P = 0.007). The differences between category A to D prisons alone were also significant (P < 0.001) (Table 4). Figure 1 shows the adjusted mean numbers of specialised services for each type and size of prison. Categories A and B and women’s prisons provided the widest variety of specialised services, on average around twice as many services as categories C and D. Medium-sized prisons had on average around 30% (10–60%) more specialised services, and large prisons 50% (20–100%) more, than small prisons.

Number of primary care services

There was no evidence that provision of primary care services was in any way influenced by prison characteristics.

Factors associated with level of GP and nurse support

GP support was highest at women’s prisons and lowest at category C prisons (P < 0.001), with averages of 2.4 (2.0–2.8) and 1.2 (0.9–1.4) surgeries per week per 100 prisoners, respectively (Figure 2 and Table 5). Differences between category A to D prisons were non-significant (P = 0.076). Small prisons held more surgeries pro rata than medium or large prisons (P < 0.001). Nurse support was also highest at women’s prisons (P < 0.001), by a wide margin, and slightly elevated at category A and B compared with category C and D prisons (P = 0.004). Nursing support, like GP support, was lower at medium and large prisons (P = 0.039).

Factors associated with chronic disease care

Provision of chronic disease services was not associated with either GP or nurse staffing levels either before (P = 0.124 and P = 0.199, respectively) or after (P = 0.086 and P = 0.285) adjustment for prison characteristics.

Discussion

Implications

The use of IT, including electronic records, was low. IT facilitates the structured care necessary for high-quality chronic disease management (Balas et al., Reference Balas and Weingarten2000; Bodenheimer et al., Reference Bodenheimer and Wagner2002; Weingarten et al., Reference Weingarten and Henning2002). Lack of IT potentially excludes prisoners from receiving an equivalent level of care compared to patients outside. The absence of systems for obtaining medical records from general practices outside is also concerning.

We chose fairly minimal standards to define a ‘full’ service for chronic diseases. Although we lack hard evidence, we would expect almost all practices outside prison to meet these criteria, whereas substantial numbers of prisons did not. The service was particularly poorly developed for heart disease. This may reflect the absence of patients with heart disease in some prisons, though all are likely to have some patients at some time. Although there are known problems with high prisoner turnover rates (White et al., Reference White and Park1999), high-quality primary care depends on good recall systems for diabetes, heart disease and asthma. Even for diabetes, where the practice of regular recall is well known and in which the benefits of structured care have been established in the prison context itself (MacFarlane et al., Reference MacFarlane and Gill1992), one-quarter of prisons had no recall system.

The low use of methadone maintenance therapy is worrying, given the known benefits including reduction in mortality rates and incarceration rates (Farrell et al., Reference Farrell1994), and needs addressing. The high level of mental health problems in prisoners (Birmingham, Reference Birmingham2003) makes the absence of talk therapies in a third of the prisons surprising. The cost of transporting prisoners to community-based facilities for treatment is generally prohibitively high (Department of Health and HM Prison Service, 2006); hence, patients in prisons without on-site services are likely to have no access at all.

Over 50% of prisons reported one or more vacancies for general nurses. While some prisons might have been actively recruiting new nurses, for example, in connection with moving provision from the prison service to the NHS, this would not fully explain why general nurse vacancies were higher than those for other staff. It may be that there are particular difficulties with recruitment or retention, or both, of general nurses. General practices outside prisons rely increasingly on nurse-led care provision (Woodroffe, Reference Woodroffe2006); the shortage of nurses in prisons is likely to impact significantly on what is achievable in prisons.

Not all differences between community and prison indicated worse prison health care. Many prisons had systems in place to deal with the management of hepatitis, which would be rare in general practice outside prison, and this may indicate appropriate targeting of services to patient need. The variety of schemes to provide out-of-hours care and pharmacy provision may reflect the need for local pragmatic arrangements in these areas.

Compared with small prisons, medium and larger prisons had a wider range of specialised services. The range of primary care services provided was similar across prisons, although GP and nurse support, relative to prisoner numbers, were lower in large- and medium-sized prisons than smaller ones. There may be economies of scale whereby the levels of staffing required to meet the need reduces as prisoner numbers increase.

Most prisons hold adult males, who are categorised by security rating. Prisoner security rating was related to specialised services but did not appear to influence provision of primary care services. Category A and B prisons provided the widest range of specialised services, considerably more than categories C and D, although only marginally more than women’s prisons. Many of the specialised services address mental health and substance abuse issues, and it is possible that patients in category A/B prisons have more of these kinds of needs compared with patients in other prisons, or that their needs can only be met within the prison environment because of security concerns. However, it is not self-evident whether male patients in category C/D prisons should receive a narrower range of specialised services simply because of their lower-security status.

Women’s prisons had relatively high levels of health care support, including both GP and nurse support, even after adjustment for size. Patterns of vacancies cannot explain this result, as the data show that vacancies were more common at women’s prisons.

Strengths and limitations of the study

We obtained a good response rate, and the survey is likely to be representative of prisons as a whole. Prison size was missing for 20% of units, and data on nurse sessions had to be imputed for a sizable number, making the results for these variables less reliable.

Although the survey methodology is useful in providing a broad overview, further in-depth study of some of the findings would be useful. This would include the extent of the apparent problems with nurse provision.

The survey relies on self-report rather than on observed activity. A key assumption is that health care managers were aware of the full breadth of services being delivered within their prison, which may not be true. The general view is that self-report tends to over-estimate or over-value available services (Ewing et al., Reference Ewing, Selassie, Lopez and McCutcheon1999); thus, the true extent of problems may be greater than identified in this survey. Because this was an exploratory study, we used an alpha level of 5%, but recognised that the number of statistical tests conducted is likely to have generated some spurious chance associations.

Implications for future research

The survey points to the need to investigate more fully why primary care provision for chronic diseases in prisons is likely to be poorer than in the community and to develop effective means to close this gap. Areas of note include the use of IT systems and nurse recruitment and retention, which may act as potential constraints on service development in prisons. Although there is international evidence about primary health care needs of prisoners (Watson et al., Reference Watson, Stimpson and Hostick,2004), there is, to our knowledge, a lack of evidence about primary health care provision in prisons worldwide; research enabling comparisons to be made would be useful. Although prisoners’ views of health care services have been investigated, there is a lack of knowledge about patient self-management of chronic diseases in prison and how best to promote self-care. There is a need also to understand why patients in some types of prisons, notably large prisons and category A/B prisons, appear to have access to a wider range of specialised services than those in other types of prisons.

Acknowledgements

We are very grateful to the health care managers who undertook to complete the questionnaire. The survey was funded through the Prison Health Research Network.

The survey was essentially a ‘self-report audit’ of existing prison services by the Department of Health. The investigators were acting as the government’s agents in conducting the audit. As such, the project was exempt from the need for Research Governance or Ethics Committee approval.
