Introduction
Worldwide prison population is growing at a rate that exceeds the rate of population growth [
1], it is estimated 11 million people are incarcerated in correctional facilities, and health-care provision in correctional systems is challenging [
2]. Prisons are not healthy places, the prisoners have a high prevalence of communicable diseases, noncommunicable diseases, and mental health problems, and many unhealthy conditions, such as overcrowding and poor hygiene, are common [
3]. In Australia, prison inmates have a history of high levels of drug use prior to imprisonment [
4]. Almost two in three prison entrants reported using illicit drugs in the prior year [
5]. In general, the health of prison inmates tends to be worse than in the general population, particularly among those who use drugs [
6].
According to Winkelman et al. [
7] reviewed the universal health coverage and incarceration, they concluded that the health care in prisons was often below the community standard and was independent of health coverage and financing in the general population. In the USA and Australia, where individuals in prison are excluded from public health insurance programmes [
7‐
9]. In USA, there is a great challenge for the delivery of health care for incarcerated individuals is that many correctional systems require high co-payments for health care which will be a barrier for accessibility [
2]. In Norway, a social health care system which they enforce the universal public insurance and restorative justice principles for the prisoners [
9].
Despite the importance of prison health care, little is known about how prison health services and governance in the previous studies [
9]. Generally, the data of healthcare for the prisoners is inadequate, even in high-income countries, prison health information systems are often archaic in nature, relying on paper-based records and needed to restructure [
7]. However, as the United Nations Basic Principles for the Treatment of Prisoners [
10] indicate that: “Prisoners shall have access to the health services available in the country without discrimination on the grounds of their legal situation” (Principle 9). The European Prison Rules also states that the general principle is that prisoners should enjoy an equivalent standard of care to persons outside prisons [
11]. Good prison healthcare governance is essential for addressing health inequity, improving the health of broader communities and improving health care in prisons [
12]. Therefore, it is necessary to understand the healthcare provision for this group of people, to insure they have the same right to health care as everyone else.
According to the World Prison Brief data [
13], total prison population (including pre-trial detainees / remand prisoners) was 54,448, and prison population rate (per 100,000 of national population) was 231 in June, 2022. There were 49 correction establishments / institutions which included 24 prisons, 12 detention houses, 2 juvenile detention and classification houses, 2 juvenile reformatory schools, 2 juvenile correctional-educational schools, 3 vocational training institutes and 4 drug abstention and treatment centers. The Taiwan Prison Act [
14], the supervisory authority of prisons is the Agency of Corrections, Ministry of Justice, and the law stimulates that “Prisons should monitor the physical and mental conditions of inmates and manage their medical treatment, preventive healthcare, screening, prevention of communicable diseases, and food hygiene.” A prison may, based on its size, can set up medical unit to process disease treatment, preventive healthcare measures, screening, prevention of communicable diseases, and dietary sanitation for inmates.
Sometimes, prisoners do not receive the medical care they need and to which they are entitled to while they are incarcerated [
15]. The Madrid Recommendation from the World Health Organization states that health protection in prisons is essential for public health and called for the support and encouragement of countries and organizations to develop a comprehensive health program within all prisons [
16]. Therefore, reorienting health service provisions, such as approaches emphasizing the importance of the early identification of key symptoms and risk factors, for prisoners is vital for the improvement of their health [
17].
Although routine in the community, patient satisfaction surveys are relatively rare in prison settings [
18]. Satisfaction surveys can provide useful insight into the experiences and expectations of patients and provide information that can help focus on the areas of patient experience that greatly impact on health outcomes [
19]. Medical achievements and National Health Insurance (NHI) have led Taiwan to have one of the most excellent health care systems in the world. In order to extend the coverage of the NHI system, prison inmates were included in the system in January 2013. When a prisoner in Taiwan suffers from a disease, the corrections agency shall comply with relevant laws and regulations to invite physicians to conduct a careful diagnosis and subsequent treatment within the institution, and the prisoner should have priority in seeking medical treatment in the correctional institution. There are more than 100 prisons’ clinics in correctional institutions under Taiwan’s current NHI scheme. Mainstreaming health care in prisons is a vital health care policy in correctional institutions that provides equal health care accessibility and availability to inmates as well as the general population. To protect the health rights of prison inmates, it is necessary to assess the effectiveness of and satisfaction with the NHI system for this group of people. Therefore, this study surveyed the profile of detention clinic care provision and patient satisfaction to examine their associated factors among drug-using inmates in a prison detention center in Taiwan.
Methods
Design and research participants
This study had a cross-sectional design. The study population included a total of 750 male drug-using inmates in a prison detention center to observe drug abuse, treatment, and prison rehabilitation in north Taiwan. The research subjects were drug-using inmates recruited from this detention center in November 2013, excluding a total of 65 inmates with court appearances, medical treatments, family interviews, foreigners who participated in technical training classes, and 100 drug-using inmates imprisoned within the prior two weeks. The remaining 585 drug inmates, including 137 undergoing rehabilitation, 133 undergoing drug addiction treatment, 307 who were already sentenced, and 8 under quarantine, were recruited for this study. This article presents a general survey of the study. Five inmates refused to provide informed consent; therefore, 580 questionnaires were analyzed.
Research Ethics and Protection
This study was reviewed and approved by the Institutional Review Board of Tri-Service General Hospital, National Defense Medical Center (TSGHIRB approval number: 2-102-05-082). The questionnaire was completed anonymously to ensure the respondents’ privacy and that the data’s confidentiality was maintained in accordance with individual laws. It was stipulated that the questionnaire’s content did not contain case statements, only for overall statistical analysis, and did not affect any rights of the prison inmate, and written informed consent was obtained from all subjects.
This study used a self-designed structural questionnaire as a survey tool. The questionnaire framework was based on the Andersen Behavioral Model and Access to Medical Care [
20,
21] as the theoretical basis and assessed the inmates according to their tendencies (i.e., predisposing factors), abilities (i.e., enabling factors), and medical care utilization needs (i.e., need factors). The Andersen health care utilization model is a conceptual model aimed at demonstrating the factors that lead to the use of health services. In practice, this study adopted this model to understand how and why participants use detention clinic care services, to assess inequality in access to detention clinic care services, and to examine the determinants that allow for equitable access to care. To understand the research subjects’ satisfaction with the prison’s medical treatment, the Patient Satisfaction Questionnaire Short Form (PSQ-18) [
22], developed by the RAND Corporation, was used as the basis of the short scale of patient satisfaction including aspects such as overall satisfaction, medical technology quality, interpersonal communication, communication, financial issues, accessibility, and convenience of consultation time. The PSQ-18’s internal consistency reliability and correlation was 0.9, the satisfaction degree used Likert’s five-point method of 1–5 points for a total of 90 points. In summary, the PSQ-18 scale is a concise, validated tool that may be applied to various settings as well as to compare interventions such as in primary care and the detention clinic care department. This study added two questions from a self-made questionnaire to ask respondents about their satisfaction with the prison’s medical lab examinations and pharmacy prescriptions; thus, the total medical satisfaction score was 100 points.
Questionnaire validity and reliability
To improve the validity and relatability of this study, the expert surface validity method (n = 5) was used to improve the questionnaire’s suitability, adequality, and readability upon completion of the questionnaire’s content design. Cronbach’s α coefficient analysis was conducted using the SPSS statistical software’s reliability analysis. The overall questionnaire’s Cronbach’s α coefficient was 0.754.
Data Processing Method
After checking and debugging, the data were decoded and entered into the Microsoft Excel 2007 software according to the decoding book’s compilation. The statistical data analysis was conducted based on the research purpose and assumptions with the SPSS for Windows 20.0 statistical package software. The main statistical methods included descriptive statistics and inferential statistics. Single-variable analysis via the statistical chi-squared test was used to explore whether there were significant correlations between basic demographic characteristics, health behaviors, economic status, health status, and detention care satisfaction. The multiple logistic regression method was used to explore the associated factors that affected satisfaction with detention clinic care utilization. The regression model uses the Andersen’s behavioral model as a simple guide to choose variables related to medical care accessibility – predisposing, enabling, need’s factors. All the results were considered statistically significant at p ≤ 0.05.
Discussion
Imprisonment affects the health and health needs of prisoners, and evidence-based prison health services can be provided for all inmates needing treatment, care, and prevention [
23]. Stone et al. [
24] stated that many correctional facilities, however, are not able to fully engage in continuous quality improvement activities mainly because of a lack of current, relevant quality models and benchmarks to serve as a basis for evaluation. However, PSQ-18 is an effective tool that is streamlined and suitable for various situations and comparative interventions [
25], such as general practitioners [
26], ophthalmology clinics [
27], and psychiatry clinics [
28], and is applied in different countries [
29,
30]. To evaluate the impact of the prison’s primary medical care, the PSQ-18 short form scale was used to assess the subjects’ satisfaction with the prison’s medical service. The present study found that nearly 70% of the subjects used the prison’s clinic care, including 68.6% in family medicine, 13.9% in dentistry, and 9.2% in psychiatry. The results were generally consistent with other studies in Taiwan [
31,
32], but the psychiatric care use was slightly lower.
This study revealed that most of the subjects came from low economic status families, consistent with another study [
5] that concluded that those in contact with the criminal justice system had higher rates of homelessness and unemployment and often came from socioeconomically disadvantaged backgrounds. This study also reported that 36.4% of the subjects were diagnosed with chronic diseases in the prior year. The Australian statistics showed that almost one-half (45%) of female entrants had a history of chronic conditions, compared with almost 3 in 10 (28%) of male subjects [
5]. The US Department of Justice also reported that prisoners and jail inmates were more likely than the general population to report ever having a chronic condition or an infectious disease [
33].
Compared with the US patient satisfaction survey based on the PSQ-18 scale [
22], the present results show that the inmates’ detention clinic care satisfaction was lower than the scale’s norms. Many previous studies have also indicated lower patient satisfaction among prison inmates. In a Norwegian study, prison inmates’ satisfaction with the health services provided were low compared with patient satisfaction in other health areas, particularly in the health service resources and quality of drug abuse treatment [
34]. According to more than 100,000 inmates surveyed in the US, more than one-half were satisfied or very satisfied with the health care they received while incarcerated. In jails, 51% of the inmates surveyed reported being satisfied or very satisfied and in prisons it was 56% of those surveyed [
33]. The results of a patient satisfaction survey conducted in the Connecticut prison system revealed that 43% of the inmates reported satisfaction with their health care [
18]. In general, the prison group reported significantly lower satisfaction compared to the community group in illicit drug treatment [
35].
The multiple logistic regression model in this survey indicates that service satisfaction provided by the detention care are associated with participant’s disposing factor - those will serve prison sentences, enabling factors such as those with custodial deposits (economic status), and the need factors such as the inmates undergoing drug addiction treatment, self-reported health status, and meet their physical health needs will also affect their perception to healthcare satisfaction. These factors needed to pay much attention in detention clinic to improve quality care for this group of people.
Taiwan’s NHI scheme may be said to be a high-performing health care system compared to many other health care systems around the world. Many characteristics contributing to the NHI’s high performance include the single payer system, used to set and regulate fees, and the imposition of a global budget system that caps total NHI expenditure [
36]. The public’s satisfaction with the Taiwanese NHI has been high; it averaged around 80% in 2014 [
37]. This study found that the highest satisfactory score was the financial aspects, and the lowest was time spent with doctors. Prison inmates have been included in Taiwan’s NHI system since January 2013. The problem associated with a short supply of medical services has since been greatly improved, and with the NHI’s financing mechanism and proper control and management, inmates, too, can have access to the reasonable use of health care resources [
38]. General speaking, this health policy removed economic obstacles, making the subjects’ access to health care easier and, therefore, it was more satisfactory than the other factors. The other factor of limited health care consultation time in the prison illustrates the subjects’ demand for quality medical care and human rights protections. Thomson et al. [
39] reported that health care provided in prisons was shifting from a basic level of care to a greater role in inmate health and identified prison inmates’ challenges and barriers to health care. The future top issues in prisons might be the confidentiality of medical information, standards of care, mental disorders and disabilities, and substance abuse and treatment [
40].
Due to the specific needs of drug inmates, this study also assessed their satisfaction with the pharmacy services, and the results demonstrated that the satisfaction score was higher than the original seven subscales. The main reasons may be the high accessibility and affordability of these services, and one full-time pharmacist to provide services in the institution. The inmates can collect prescriptions immediately rather than waiting long for the medicines. There is good evidence to support the expanding role of pharmacists as primary care providers through activities such as direct patient care, health care clinics, and medication management in the corrections setting [
41].
This study’s limitations were as follows: The survey subjects were required to sign an interview consent form. The subjects may have been concerned about their privacy and their own rights and interests, which could have affected the credibility of their answers to sensitive questions. As the questionnaire involved self-reported data, recall bias might also have occurred. There are many issues did not considered in this survey which might affect their healthcare needs and satisfaction, such as lacking of health conditions of the participants, undergoing withdrawal management and being sentenced to prison, key contextual factors etc. Although the PSQ-18 scale is an adaptable, reliable, and validated tool for use in various settings [
42], including Asian countries such as Hong Kong [
43], China [
44], Malaysia [
45], Thailand [
46], and the Philippines [
47]. There are a few studies that have been conducted in Taiwan that can be used as a comparison for this study. However, this study was one of the first to assess patient satisfaction among drug-using inmates in Taiwan, so the data can provide useful information for future health care policy initiatives to improve their quality of care.
